The invention provides a positioning device.

In an embodiment of the present invention, as shown in fig. 1 to 3, the positioning device includes a housing 100, a device body 200, and a sealing member 300, wherein the housing 100 is provided with a mounting cavity 110, and a signal hole 140 communicating with the mounting cavity 110 is formed; the device main body 200 is arranged in the installation cavity 110; the sealing member 300 is disposed outside the housing 100 and is movable relative to the housing 100 to have a first position and a second position; in the first position, the seal 300 seals the signal aperture 140 to seal the mounting cavity 110; in the second position, the signal hole 140 is exposed outside the housing 100, and the mounting cavity 110 is communicated with the external environment through the signal hole 140, so that the device main body 200 can emit a positioning signal through the signal hole 140.

It will be appreciated that when the positioning device works, the signal hole 140 needs to be exposed, and no shielding exists between the device body 200 and the signal hole 140 in the mounting cavity 110, so that the device body 200 can emit the positioning signal through the signal hole 140. However, the signal hole 140 is exposed, which easily causes external water to enter the mounting cavity 110, thereby shorting the circuit structure of the device body 200. In the technical scheme of the invention, the sealing element 300 is movably arranged at the outer side of the shell 100, and when the positioning device has no water inflow risk, the sealing element 300 can be stably positioned at the second position, so that the signal hole 140 is exposed at the outer side of the shell 100, and the positioning device can work normally; when water is met, the sealing element 300 can move to the first position to seal the signal hole 140, so that the influence on the circuit structure of the device main body 200 caused by excessive water inflow in the mounting cavity 110 is avoided. Therefore, the invention improves the tightness of the positioning device when meeting water, thereby improving the waterproof performance of the positioning device, being beneficial to reducing the probability of failure of the device main body 200 of the positioning device, avoiding frequent maintenance or replacement of the device main body 200, and reducing the maintenance cost of the positioning device.

Further, in the present embodiment, as shown in fig. 1 to 3, the sealing member 300 includes a first sealing member 310, and in the first position, the first sealing member 310 is inserted into and seals the signal hole 140. In this embodiment, the shape of the first sealing member 310 is matched with the shape of the signal hole 140, the first sealing member 310 is inserted into the signal hole 140, and the outer periphery of the first sealing member 310 abuts against the inner periphery of the signal hole 140, so that the signal hole 140 can be sealed. Of course, in other embodiments, the sealing member 300 may be disposed to cover the signal hole 140 outside the housing 100 in the first position, so as to seal the signal hole 140.

Further, in this embodiment, as shown in fig. 1 to 3, the seal 300 further includes a second seal 320, the second seal 320 is provided with a first guide hole 321, an axial direction of the first guide hole 321 is parallel to an axial direction of the signal hole 140, the first seal 310 is movably disposed in the first guide hole 321, and the second seal 320 abuts against an outer side of the housing 100; in the second position, the second sealing member 320 is disposed away from the signal hole 140, so that the signal hole 140 is exposed outside the housing 100; in the first position, the first guiding hole 321 is opposite to the signal hole 140, so that the first sealing member 310 can be inserted into the signal hole 140. It will be appreciated that the second position of the seal 300 corresponds to the second seal 320 being in a position that does not block the signal aperture 140, and the first seal 310 being opposite the housing 100 outside the signal aperture 140 and being at least partially within the first guide aperture 321 of the seal 300; the first position of the sealing member 300 corresponds to the second sealing member 320 being located opposite to the first guide hole 321 and the signal hole 140, and the first sealing member 310 being inserted into and sealing the signal hole 140. That is, the second positions of the first seal 310 and the second seal 320 are located at the sides of the signal hole 140, the second seal 320 drives the first seal 310 to move toward the signal hole 140, and when the second seal 320 moves to the first guide hole 321 and the signal hole 140 to be opposite, that is, to reach the first position, the first seal 310 is inserted into the signal hole 140, that is, to reach the first position, thereby sealing the signal hole 140. In this embodiment, by providing the second sealing member 320, the movement of the first sealing member 310 can be better guided, and the second sealing member 320 abuts against the outer side of the housing 100, so that external water cannot enter the signal hole 140 through between the second sealing member 320 and the housing 100, which is beneficial to improving the sealing effect on the signal hole 140. Of course, in other embodiments, a guide groove may be provided on the housing 100 to guide the movement of the first seal 310 from the second position to the signal hole 140.

Further, in the present embodiment, as shown in fig. 1 to 3, the positioning device further includes an expansion member 410 disposed outside the housing 100, the expansion member 410 is located on a side of the sealing member 300 in the second position away from the signal hole 140, and the expansion member 410 can drive the sealing member 300 from the second position to the first position. Specifically, in the second position, the expansion members 410 of the signal holes 140 are disposed on opposite sides of the second sealing member 320, and when the positioning device encounters water, the expansion members 410 can expand to drive the second sealing member 320 to move in a direction away from the expansion members 410, so that the second sealing member 320 can drive the first sealing member 310 to move in a direction close to the signal holes 140 until the first guiding holes 321 are opposite to the signal holes 140, the first sealing member 310 is inserted into the signal holes 140, and the sealing member 300 reaches the first position under the driving of the expansion members 410, thereby sealing the signal holes 140. Wherein the expansion member 410 may be an expansion rubber or an expansion sponge, etc. Of course, in other embodiments, the second sealing member 320 may be made of an expandable material, and the second sealing member 320 expands when it encounters water, so as to drive the first sealing member 310 to move to a position opposite to the signal hole 140; or the sensor detects that the positioning device has no water inflow risk, the second sealing element 320 is pushed to the first position from the second position by the pushing arm, specifically, one end of the pushing arm is rotatably connected to the housing 100, the other end of the pushing arm is connected to the sealing element 300, in the second position, the pushing arm is located at one side of the sealing element 300 away from the signal hole 140 and is inclined to the distribution direction of the sealing element 300 and the signal hole 140, when the sensor detects that the outside of the housing 100 is exposed to the environment with excessive water, the pushing arm is driven to rotate around the housing 100, and the pushing arm swings in a trend gradually parallel to the distribution direction of the sealing element 300 and the signal hole 140, so that the sealing element 300 can be pushed towards the direction of the signal hole 140, and the sealing element 300 can move to the first position.

Further, in the present embodiment, as shown in fig. 1, a first limiting protrusion 120 is disposed outside the housing 100, the first limiting protrusion 120 is located on a side of the expansion member 410 away from the sealing member 300, and in the second position, two opposite sides of the expansion member 410 are respectively abutted against the first limiting protrusion 120 and the sealing member 300 (i.e. the second sealing member 320). In this way, once the expansion member 410 expands when encountering water, the second sealing member 320 can be pushed to move to a position close to the signal hole 140, which is beneficial to improving the sensitivity of the waterproof structure of the positioning device and guaranteeing the waterproof performance of the positioning device. Of course, in other embodiments, when the second sealing member 320 is at the second position, the two opposite sides of the expansion member 410 are spaced apart from the first limiting protrusion 120 or the second sealing member 320, and the expansion member 410 pushes the second sealing member 320 only when the water content in the external environment reaches a certain level, so that the second sealing member 320 cannot move when the water content in the external environment is insufficient to interfere with the circuit structure of the device subject, so that the second sealing member 320 can be prevented from shielding the signal hole 140 and affecting the device main body 200 to emit the positioning signal.

Further, in the present embodiment, as shown in fig. 1, a second limiting protrusion 130 is disposed outside the housing 100, in the second position, the second limiting protrusion 130 is located at a side of the signal hole 140 away from the sealing member 300, and in the first position, the sealing member 300 abuts against the second limiting protrusion 130. Specifically, the second sealing element 320 abuts against the second limiting protrusion 130 when in the first position, so that excessive expansion of the expansion element 410 can be avoided, even if the expansion element 410 still has an abutting force on the second sealing element 320 after the second sealing element 320 reaches the first position, the second sealing element 320 can be stably located in the first position under the limitation of the second limiting protrusion 130, and the first sealing element 310 can be correspondingly stably located in the first position, so that effective sealing of the signal hole 140 is ensured. Of course, in other embodiments, a limiting groove may be formed on the outer side of the housing 100, and when the second sealing member 320 reaches the first position, the side of the expansion member 410 near the signal hole 140 abuts against the groove wall of the limiting groove, so that the expansion member 410 cannot push the second sealing member 320.

In this embodiment, as shown in fig. 1 to 3, the second sealing element 320 and the expansion element 410 are respectively provided with a ring shape, wherein a plurality of holes are provided on the expansion element 410 along the circumferential direction at intervals to increase the expansion speed of the expansion element 410, and further, the first limiting protrusion 120 and the second limiting protrusion 130 may be respectively provided with a ring shape to better realize the limiting function.

Further, in this embodiment, as shown in fig. 3, the first sealing member 310 is provided with a first magnetic member 311, and a second magnetic member 510 for attracting with the first magnetic member 311 is disposed in the mounting cavity 110, so as to drive the first sealing member 310 to be inserted into the signal hole 140 when the first guiding hole 321 is opposite to the signal hole 140. Thus, when the second sealing member 320 moves to the first position, the first magnetic member 311 is attracted by the second magnetic member 510, and the first magnetic member 311 can drive the first sealing member 310 to be inserted into the signal hole 140, so as to seal the signal hole 140. Of course, in other embodiments, the second sealing member 320 may be provided with a magnet that repels the first magnetic member 311, and in the second position, the first sealing member 310 is repelled to be in contact with the outer wall of the housing 100, and in the first position, the first guiding hole 321 is opposite to the signal hole 140, and under the repulsion of the magnet, the first magnetic member 311 can also drive the first sealing member 310 to be inserted into the signal hole 140.

Further, in this embodiment, as shown in fig. 1 and 2, the positioning device further includes a first elastic member 322, two ends of the first elastic member 322 are respectively connected to the housing 100 and the second sealing member 320, and the second sealing member 320 has a tendency to be maintained in the second position under the action of the first elastic member 322. When the second sealing element 320 is at the first position, the first elastic element 322 is correspondingly in an elastic deformation state, when the second sealing element 320 is at the second position, the first elastic element 322 can be in a natural state or in an elastic deformation state, however, the deformation amount at this time is smaller than the deformation amount corresponding to the first elastic element 322 when the second sealing element 320 is at the first position, the elastic force of the first elastic element 322 received by the second sealing element 320 is counteracted by the pushing force of the expansion element 410, so when the expansion element 410 is in the original state, the first elastic element 322 can limit the movement of the second sealing element 320 to the first position, the second sealing element 320 can be stably at the second position, and the second sealing element 320 is prevented from shielding the signal hole 140, and the device main body 200 is affected to emit positioning signals. When the expansion member 410 begins to expand to push the second sealing member 320, the pushing force applied to the second sealing member 320 exceeds the elastic member applied by the first elastic member 322, so that the second sealing member 320 can move like the first position. Of course, in other embodiments, the side of the expansion element 410 away from the second sealing element 320 is fixedly connected to the housing 100, and the side of the expansion element 410 close to the second sealing element 320 is connected to the second sealing element 320, so that the second sealing element 320 can be stably located in the second position when the expansion element 410 is in the original state.

Further, in this embodiment, as shown in fig. 1 to 3, the positioning device further includes a second elastic member 312, two ends of the second elastic member 312 are respectively connected to the first sealing member 310 and the second sealing member 320, and in the second position, the second elastic member 312 can apply an elastic force to the first sealing member 310 to limit the first sealing member 310 from being separated from the first guiding hole 321. Specifically, one end of the first seal member 310 abuts against the outer wall of the housing 100, so that the first seal member 310 is pressed by the housing 100, and the other end is pressed by the elastic force of the second elastic member 312, so that the elastic force and the pressing force of the first seal member 310 can be offset in the axial direction of the first guide hole 321, and the first seal member 310 can be stably located at the second position without being separated from the first guide hole 321. Of course, in other embodiments, a limiting protrusion may be disposed on a side of the first guiding hole 321 away from the housing 100 to limit the first sealing member 310 from being separated from the first guiding hole 321.

Further, in this embodiment, as shown in fig. 3, a water absorbing member 420 disposed in the mounting cavity 110 to avoid the signal hole 140 is further disposed. Thus, when the external environment impacts the positioning device with too much water, water enters the mounting cavity 110 before the sealing member 300 reaches the first position, and the water absorbing member 420 can absorb the water without affecting the circuit structure of the device body 200. And, the water absorbing member 420 is disposed so as to avoid the signal hole 140, that is, the water absorbing member 420 does not block the device body 200 from emitting the positioning signal through the signal hole 140. Of course, in other embodiments, a water blocking wall may be provided on the periphery of the device body 200, and the device body 200 may be protected when water is slightly introduced into the installation cavity 110.

Without loss of generality, as shown in fig. 2, the housing 100 has a first end wall 101, a second end wall 102, and a side wall 103 connecting the first end wall 101 and the second end wall 102, the first end wall 101, the second end wall 102, and the side wall 103 enclose to form the mounting cavity 110, the device body 200 is disposed on an inner side of the first end wall 101, the first limiting protrusion 120 is located on a side of the second limiting protrusion 130 near the second end wall 102, the signal hole 140 is opened on the side wall 103, and the water absorbing member 420 is disposed opposite to the side wall 103 and avoiding the signal hole 140. In this way, the water absorbing member 420 can absorb water entering from the signal hole 140 more quickly to prevent water from rushing into the inside of the installation cavity 110.

Further, in this embodiment, as shown in fig. 3, a limiting member 500 is further disposed in the installation cavity 110, the limiting member 500 is disposed opposite to the wall of the housing 100 in which the signal hole 140 is disposed, the water absorbing member 420 is disposed between the limiting member 500 and the wall of the housing 100, and the limiting member 500 is movably disposed in the installation cavity 110 so as to have a third position and a fourth position; the space between the stopper 500 and the wall of the housing 100 in the third position is larger than the space between the stopper 500 and the wall of the housing 100 in the fourth position; the limiter 500 is correspondingly in the third position when the seal 300 is in the first position, and the limiter 500 is correspondingly in the fourth position when the seal 300 is in the second position. That is, the stopper 500 is disposed with respect to the sidewall 103 of the housing 100, the water absorbing member 420 is disposed between the sidewall 103 of the housing 100 and the stopper 500, when the stopper 500 is in the fourth position, the space between the stopper 500 and the sidewall 103 of the housing 100 is smaller, that is, the space of the side of the stopper 500 facing away from the water absorbing member 420 can be larger, the apparatus body 200 is also mounted therebetween, thus, the apparatus body 200 can be easily detached and mounted and the air fluidity can be improved, and when the stopper 500 is in the third position, the space between the stopper 500 and the sidewall 103 of the housing 100 is larger, the volume of the water absorbing member 420 which can be expanded is larger, that is, more water can be absorbed, which is advantageous for improving the waterproof performance of the positioning apparatus.
