In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

Generally, the camera lens will inevitably shake and cause the picture to be blurred during shooting. Especially for the camera lens of smartphones, medical equipment, vehicle-mounted equipment, etc., the shaking amplitude during shooting is large, and it is difficult to satisfy users. The need for high-quality shooting. A common solution is to provide a driving mechanism on the lens or the photosensitive element to control the movement of the lens group or the photosensitive element, thereby compensating for the effects of shooting jitter. However, due to the large weight and size of the lens and the photosensitive element, it is still difficult to achieve an anti-shake effect higher than one axis (for example, two-axis) after cooperating with the driving mechanism, resulting in poor image anti-shake effect. To this end, the embodiments of the present application provide an anti-shake component, a camera module, and an electronic device to solve the problem of insufficient anti-shake performance caused by poor matching of the current anti-shake structure.

Referring to FIGS. 1 and 2, in an embodiment of the present application, the anti-shake assembly 10 includes a first light path changing element 110 and a second light path changing element 120 arranged adjacently. In this embodiment, the first light path changing element 110 and the second light path changing element 120 both have a triangular prism structure, or the triangular prism structure can be understood as a triangular prism structure. The first light path changing element 110 has a first rotation axis 1104, and the first light path changing element 110 can rotate around the first rotation axis 1104, the second light path changing element 120 has a second rotation axis 1204, and the second light path changing element 120 can Rotating around the second rotation axis 1204, the first rotation axis 1104 is perpendicular to the second rotation axis 1204. The first light path changing element 110 includes a first reflecting surface 1102, and the second light path changing element 120 includes a second reflecting surface 1202. The first reflecting surface 1102 is used for reflecting incident light to the second reflecting surface 1202, and the second reflecting surface 1202 is used for To reflect the incident light out of the anti-shake component 10.

Figures 1 and 2 show direction A, direction B and direction C, while direction-A is the opposite direction of direction A, direction-B is the opposite direction of direction B, and direction-C is the opposite direction of direction C. This application The direction A of is only a reference direction, and the direction A can actually be any direction. Direction A, direction B, and direction C are perpendicular to each other. In one embodiment, the first rotation axis 1104 is parallel to the direction C, and the second rotation axis 1204 is parallel to the direction A. Correspondingly, the first reflecting surface 1102 can rotate around the first rotation axis 1104, and the second reflecting surface 1202 can rotate around the second rotation axis 1204. The first reflective surface 1102 can reflect the light incident in the direction A, so that the incident light is reflected to the second reflective surface 1202 in the direction B, and the second reflective surface 1202 can reflect the light from the first reflective surface 1102 in the direction C to prevent Tremor component 10. At the same time, the angle of light reflection can be changed by adjusting the angle at which the first reflecting surface 1102 rotates around the first axis of rotation 1104; similarly, the angle of light incident on the second reflecting surface 1202 can be changed by controlling the angle at which the second reflecting surface 1202 rotates around the second axis of rotation 1204. The angle of light reflection at the reflecting surface 1202. As mentioned above, by controlling the rotation direction and the rotation amplitude of the first reflective surface 1102 and the second reflective surface 1202, the exit direction and exit angle of the emitted light from the anti-shake assembly 10 can be adjusted so that the exit light on the virtual imaging surface is perpendicular to each other. Adjustable displacement occurs in the two directions of, so the anti-shake component 10 can bring a dual-axis anti-shake effect to the camera module.

The solution that the first rotation axis 1104 is perpendicular to the second rotation axis 1204 is only one of the preferred solutions of the present application. In other embodiments, the first rotation axis 1104 and the second rotation axis 1204 are not parallel to each other, for example, the first rotation axis 1104 and the second rotation axis 1204 are at 10°, 20°, 30°, or 45°. Angle. Although the above arrangement may cause one of the first light path changing element 110 and the second light path changing element 120 to rotate, the light finally emitted from the anti-shake assembly 10 will be offset in two mutually perpendicular directions, However, through the analysis of the algorithm in the driving system, the rotation of the other reflecting unit can be adjusted synchronously, so that the deviation of the light in the unexpected direction can be corrected, and finally the emitted light is only deviated in a certain expected direction.

Specifically, in one embodiment, both the first light path changing element 110 and the second light path changing element 120 are in a right-angle prism structure. The first light path changing element 110 includes two opposite bottom surfaces that are right-angled triangles and are parallel to each other, a first side surface 1110 corresponding to the long side of the bottom surface, a second side surface 1120 and a third side surface 1130 respectively corresponding to the two short sides of the bottom surface; The two light path changing elements 120 include two opposite bottom surfaces of right triangles, a fourth side surface 1240 corresponding to the long side of the bottom surface, and a fifth side surface 1250 and a sixth side surface 1260 respectively corresponding to the two short sides of the bottom surface. The first side surface 1110 forms the first reflective surface 1102 of the first light path changing element 110, and the fourth side surface 1240 is the second reflective surface 1202 of the second light path changing element 120. The first reflective surface 1102 and the second reflective surface 1202 may be The metal plating layer with high reflectivity is formed. When the reflectivity in this application is greater than 80%, it can be understood as high reflectivity. The bottom surface of the first light path changing element 110 is perpendicular to the bottom surface of the second light path changing element 120, and the second side surface 1120 of the first light path changing element 110 faces the fifth side surface 1250 of the second light path changing element 120.

In the embodiment of the present application, for the convenience of description, the third side surface 1130 may be used as the incident surface of the anti-shake assembly 10 and the sixth side surface 1260 may be used as the exit surface of the anti-shake assembly 10. In addition, the direction A, the direction B, and the direction C are perpendicular to each other, and in an ideal situation, the first rotation axis 1104 is parallel to the direction C, and the second rotation axis 1204 is parallel to the direction A. The three side edges of the first light path changing element 110 are parallel to each other, and are always parallel to the first rotation axis 1104 when rotating around the first rotation axis 1104; the three side edges of the second light path changing element 120 are parallel to each other and are moving around the second The rotating shaft 1204 is always parallel to the second rotating shaft 1204 when rotating.

Further, in an initial state, the first side surface 1110 and the fifth side surface 1250 form an angle of 45°. At this time, external light can enter the first light path changing element 110 from the third side surface 1130 in the direction A, and the incident light will be internally reflected when it reaches the first side surface 1110, and is reflected in the direction B to the second side surface 1120 to be reflected from The first light path changing element 110 exits, the light emitted from the first light path changing element 110 enters the second light path changing element 120 from the fifth side surface 1250, and then internal reflection occurs when it reaches the fourth side surface 1240, and is reflected in the direction C to the first The six sides 1260 emit light from the second light path changing element 120.

At this time, when the anti-shake component 10 moves in the B direction or the -B direction relative to the subject, the light from the subject will be offset from the original path after being reflected by the first reflecting surface 1102. The rotation of the first light path changing element 110 can be controlled to change the reflected light path of the light, so as to compensate for the reflected light path, so that the final imaged image can be restored to the original position. Correspondingly, when the anti-shake component 10 moves in the C direction or the -C direction relative to the subject, the light from the subject will be offset from the original path after being reflected by the second reflecting surface 1202. The second light path changing element 120 can be controlled to rotate to change the reflected light path of the light, thereby compensating for the reflected light path, so that the final imaged image can be restored to the original position. Therefore, by controlling the rotation of the first light path changing element 110 and the second light path changing element 120, the incident light can be deflected in mutually perpendicular directions when being reflected by the first reflecting surface 1102 and the second reflecting surface 1202, and passing through The rotation direction and amplitude of the first light path changing element 110 and the second light path changing element 120 are compensated for the shaking during shooting, so that the effect of dual-axis anti-shake can be realized.

On the other hand, since the first light path changing element 110 and the second light path changing element 120 in the above-mentioned anti-shake assembly 10 are arranged adjacently, the two can be assembled into one part before being applied to the camera module. The vertical alignment between the rotating shafts facilitates the installation of the module and the accuracy of the anti-shake effect, and at the same time can improve the complex optical path calibration process in the later module assembly. Above, the anti-shake component 10 can provide excellent optical anti-shake function for the camera module

It should be noted that due to process errors, the descriptions of parallel and vertical in the embodiments of this application are only solutions in an ideal state. It should be understood that roughly parallel and roughly vertical should also be regarded as belonging to this application, respectively. The description of parallel and perpendicular within the category. For example, an angular deviation of 0-5° from the ideal state should also be considered in the category of parallel and perpendicular. At the same time, it should be noted that the direction A, direction B, and direction C are used as reference directions, and the vertical relationship between the three should be regarded as a strict vertical relationship in an ideal state.

When describing the light path, the propagation of light in a certain direction does not mean that the propagation direction must be parallel to that direction. In fact, when the propagation direction of the light is in an acute angle relationship with a certain direction, it can also be said that the light propagates in that direction.

In addition, the first light path changing element 110 and the second light path changing element 120 described in some embodiments of the present application are in a triangular prism structure or a plane mirror structure, which does not mean that they are strictly a triangular prism structure or a plane mirror structure. In order to drive the first light path changing element 110 and the second light path changing element 120 to rotate, the first light path changing element 110 and the second light path changing element 120 need to be additionally provided with a supporting structure and a driving structure in structure.

In some embodiments, the first light path changing element 110 and the second light path changing element 120 both have a right-angled triangular prism structure. The right-angled prism structure of the first light path changing element 110 and the second light path changing element 120 is only an ideal structure. In some embodiments, the first light path changing element 110 and the second light path changing element 120 may be prisms with an acute triangle bottom surface or The bottom surface is a triangular prism with an obtuse angle. And when the bottom surface of the prism structure is not a non-isosceles triangle, the two short sides of the same bottom surface can be the same in length or different in length. The setting of the triangular prism structure can be adapted to the common camera module structure, which is convenient for assembly. In comparison, the triangular prism structure has greater inertia, which can effectively prevent the first optical path changing element 110 and the second optical path changing element 120 from being too sensitive when rotating, and avoiding the compensation speed of the optical path faster than the jitter of the module. Speed can not achieve effective anti-shake effect.

In addition to the above-mentioned arrangement of the second side 1120 facing the fifth side 1250, the first light path changing element 110 and the second light path changing element 120 can also be arranged in other ways, so as to bring different effects to the anti-shake assembly 10.

Further, in some embodiments, the first optical path changing element 110 is provided with a first rotating column 1112, the first rotating column 1112 is arranged on the outside of the triangular prism structure and on the first side surface 1110, and the first optical path changing element 110 can circulate around. The first rotating column 1112 rotates, and the axis of the first rotating column 1112 serves as the first rotating shaft 1104; the second optical path changing element 120 is provided with a second rotating column 1242, and the second rotating column 1242 is arranged on the outside of the triangular prism structure. On the fourth side surface 1240, the second light path changing element 120 can rotate around the second rotating column 1242, and the axis of the second rotating column 1242 serves as the second rotating shaft 1204. In addition, the first rotating column 1112 is disposed on the first side surface 1110 and is parallel to the side edge of the first light path changing element 110, and the second rotating column 1242 is disposed on the fourth side surface 1240 and is parallel to the side edge of the second light path changing element 120, Since the first light path changing element 110 reflects the incident light to the second light path changing element 120 by internal reflection, disposing the first rotating column 1112 on the first side surface 1110 will not significantly affect the light on the first light path changing element 110. Reflection in. On the contrary, by arranging the first rotating column 1112 at a position close to the first reflecting surface 1102, the rotation range of the first light path changing element 110 can be reasonably controlled under the premise of ensuring that the first light path changing element 110 has a proper angle of rotation. The anti-shake component 10 only needs to reserve a small rotation space to enable the first optical path changing element 110 to have a reasonable rotation angle range, thereby achieving the expected optical anti-shake effect, and effectively reducing the anti-shake component 10 volume. Similarly, arranging the second rotating column 1242 at a position close to the second reflecting surface 1202 also has the same effect, which will not be repeated here.

3, in some embodiments, the bottom surface of the first light path changing element 110 is perpendicular to the bottom surface of the second light path changing element 120, and the first side surface 1110 faces the fourth side surface 1240, but only part of the first side surface 1110 corresponds to the second side surface. 1120. At the same time, the side edge of the first light path changing element 110 is perpendicular to the side edge of the second light path changing element 120, the first rotation axis 1104 is parallel to the side edge of the first mirror, and the second rotation axis 1204 is parallel to the second reflection. The side edge of the mirror. In particular, the first side surface 1110 serves as both the incident surface and the exit surface of the first light path changing element 110, and the fourth side surface 1240 serves as the entrance surface and the exit surface of the second light path changing element 120 at the same time. In addition, the second side surface 1120 and the third side surface 1130 form a first reflecting surface 1102, the second side surface 1120 is used to reflect incident light to the third side surface 1130, and the third side surface 1130 is used to reflect incident light to the fifth side surface 1250; The fifth side surface 1250 and the sixth side surface 1260 form a second reflective surface 1202, and the fifth side surface 1250 is used to reflect incident light to the sixth side surface 1260.

In the above structure, the light incident on the anti-shake component 10 in the direction B will also enter the first optical path changing element 110 from the first side 1110 in the direction B, and the incident light will sequentially occur on the second side 1120 and the third side 1130. Reflected and exit from the first side surface 1110 to the fourth side surface 1240 in the direction -B to enter the second light path changing element 120. The light incident to the second light path changing element 120 then sequentially on the fifth side surface 1250 and the sixth side surface 1260 Internal reflection occurs, and finally exits from the fourth side surface 1240 in the direction B to leave the anti-shake assembly 10. In addition, by controlling the rotation direction and the rotation amplitude of the first light path changing element 110 and the second light path changing element 120, the light emitted from the fourth side surface 1240 can be shifted in two mutually perpendicular directions, thereby realizing double Shaft anti-shake effect.

In some embodiments, the first side surface 1110 also faces the second side surface 1120, but at this time, the first side surface 1110 forms a first reflective surface 1102, and the second side surface 1120 serves as a second reflective surface 1202. The first light path changing element 110 When the external light enters the first side surface 1110, external reflection occurs, and when the external light enters the second side surface 1120, external reflection occurs as well. The first rotation axis 1104 and the second rotation axis 1204 are respectively parallel to the side edges of the first light path changing element 110 and the second light path changing element 120. At this time, the light from the subject will occur when it is incident on the first reflecting surface 1102. It is externally reflected and reflected to the second reflective surface 1202, and then external reflection also occurs on the second reflective surface 1202, so that the second reflective surface 1202 is finally reflected out of the anti-shake assembly 10. In addition, by controlling the rotation direction and the rotation amplitude of the first light path changing element 110 and the second light path changing element 120, the light reflected by the fourth side surface 1240 can be shifted in two mutually perpendicular directions, thereby realizing double Shaft anti-shake effect. In the above structure, the incident light can be reflected externally on the first side surface 1110 and the fourth side surface 1240 in turn, that is, the incident light beam is directly reflected on the external surfaces of the first light path changing element 110 and the second light path changing element 120, without Entering the inside of the prism structure can effectively reduce the light loss, so that the anti-shake component 10 can avoid the reduction of light flux while achieving the anti-shake function, thereby improving the image quality.

In addition to the triangular prism structure, at least one of the first light path changing element 110 and the second light path changing element 120 may also have other structures with a planar reflective surface, as long as the planar reflective surface can serve as the first reflective surface 1102 or the second reflective surface 1202 is fine. In some embodiments, the structure with a flat reflecting surface may be a flat reflecting mirror structure. The flat reflecting mirror includes a front surface and a rear surface parallel to each other, and the front surface or the rear surface can be used as the above-mentioned flat reflecting surface.

In one embodiment, the first light path changing element 110 and the second light path changing element 120 are both in a plane mirror structure, and the front surface of the first light path changing element 110 faces the front surface of the second light path changing element 120, and the back surface serves as The first reflective surface 1102 and the rear surface of the second optical path changing element 120 serve as the second reflective surface 1202. In comparison, the flat mirror structure has a small volume, which can also effectively reduce the volume of the anti-shake assembly 10, which is beneficial to the miniaturized design and assembly of the anti-shake assembly 10. In this embodiment, the first rotating column 1112 may be disposed on the back surface of the first light path changing element 110, and the second rotating column 1242 may be disposed on the back surface of the second light path changing element 120. In other embodiments, the positions of the first rotating column 1112 and the second rotating column 1242 are not limited to the above embodiments, as long as the first light path changing element 110 and the second light path changing element 120 can be rotated in the desired direction. .

It can be seen from the above embodiments that the incident light in some embodiments enters the first light path changing element 110 to achieve internal reflection inside the first light path changing element 110, and is reflected to the second reflecting surface 1202; while in other embodiments The incident light in the first light path changing element 110 is externally reflected on the outer surface of the first light path changing element 110 to be reflected to the second reflective surface 1202. It is understandable that, in one embodiment, by providing a reflective coating on a certain side surface of the first light path changing element 110, the side surface can reflect light from both sides to form the first reflective surface 1102, that is, it can reflect The light from the inside of the first light path changing element 110 (internal reflection) can also reflect the light from the outside of the first light path changing element 110 (external reflection). In addition to providing a reflective coating, the first reflective surface 1102 can also be formed by making a certain side surface capable of reflecting light in any manner. Of course, for structures with special reflective light paths, such as the above-mentioned solution using a triangular prism structure to achieve two internal reflections, reflective coatings can also be used to make the two sides of the triangular prism structure reflect light from the inside of the triangular prism structure. Therefore, the two side surfaces can jointly form the first reflective surface 1102. At this time, the first side surface 1110 has a high transmittance to incident light, for example, it can transmit more than 80% of light. Correspondingly, the arrangement of the second reflecting surface 1202 in the second light path changing element 120 of some embodiments may also be the same as that of the first reflecting surface 1102. The specific details of the second reflecting surface 1202 will not be repeated here. In addition, The fourth side surface 1240 has a high transmittance to the light from the first light path changing element 110, for example, it can transmit more than 80% of the light.

In terms of driving and rotating support, in some embodiments, the anti-shake assembly 10 includes a housing on which at least one magnet and two elastic pieces are provided, and the first light path changing element 110 and the second light path changing element 120 are both provided with Coil. The two elastic pieces abut against the first light path changing element 110 and the second light path changing element 120, respectively, and the coils on the first light path changing element 110 and the second light path changing element 120 can be matched with the magnet, so that the coil can be generated with the magnet after being energized. The magnetic force acts to drive the rotation of the first light path changing element 110 and the second light path changing element 120, and the elastic sheet can stabilize, buffer and reset the first light path changing element 110 and the second light path changing element 120. The position of the coil on the first light path changing element 110 and the second light path changing element 120 is not unique, as long as it does not hinder the rotation of the reflecting unit and hinder the propagation of incident and outgoing light. On the other hand, in some embodiments, when the first light path changing element 110 is provided with a first rotating column 1112 and the second light path changing element 120 is provided with a second rotating column 1242, the first rotating column 1112 will be connected to the anti-rotation On the shell of the anti-shake assembly 10, the second rotating column 1242 is also rotatably connected to the shell of the anti-shake assembly 10.

Referring to FIG. 4, some embodiments of the present application further provide a camera module 20, which includes a lens assembly 210, a photosensitive element 220, and the anti-shake assembly 10 in any one of the above embodiments. Wherein, the lens assembly 210 includes one, two or more lenses, and the optical axis of each lens should be in the same straight line to achieve alignment. The lens assembly 210 is disposed on the exit light path of the anti-shake assembly 10 to correspond to the second reflective surface 1202. The second reflective surface 1202 can direct the light from the first reflective surface 1102 (not shown in the figure due to the viewing angle) to the direction C Reflected to the lens assembly 210. In addition, the photosensitive element 220 is disposed on the image side of the lens assembly 210 to receive light from the second reflecting surface 1202 and adjusted by the lens assembly 210. The photosensitive surface of the photosensitive element 220 can be regarded as the camera module 20. The imaging surface. The photosensitive element 220 may be a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor). At this time, by adjusting the rotation direction and angle of the first light path changing element 110 and the second light path changing element 120, the deviation of the image of the subject on the imaging surface can be controlled, so that the final imaging on the photosensitive element 220 can be achieved. Shake compensation in two mutually perpendicular directions to achieve dual-axis anti-shake function.

Referring to FIG. 5, in other embodiments, the lens assembly 210 may also be disposed on the incident light path of the first light path changing element 110, that is, the first light path changing element 110 is disposed on the image side of the lens assembly 210, and the photosensitive element 220 is disposed at The exit light path of the second light path changing element 120 (not shown due to viewing angle reasons). The light from the subject will reach the first reflecting surface 1102 after being adjusted by the lens assembly 210, the light will reach the second reflecting surface 1202 after being reflected by the first reflecting surface 1102, and finally be reflected by the second reflecting surface 1202 to the photosensitive element 220.
