The present invention relates to a battery accommodating structure of a portable electronic device, and more particularly, to include a stopper that prevents the battery from being inserted in the reverse direction, thereby preventing damage or deformation of the connection terminal of the portable electronic device due to the reverse insertion of the battery. Does not relate to a battery housing structure.

Recently, a widely used digital camera, a portable multimedia player (PMP), a notebook PC, a mobile phone such as a mobile phone is equipped with a battery for power supply. Since such portable electronic devices must be easy to carry, the battery must not only stably supply power to the portable electronic device but also maintain the state in which the battery is mounted on the portable electronic device.

Since a battery inserted to be detachably inserted into a portable electronic device may be inserted in a reverse direction of a power source, a user should be careful when inserting the battery into the portable electronic device. In a typical portable electronic device, the electrode terminals formed on the battery are asymmetrically disposed in order to prevent the polarity of the power supply of the battery from being reversed.

However, even when the electrode terminals of the battery are asymmetrically disposed, it is not preferable that the battery is inserted in the reverse direction. The reason is that a connection terminal electrically connected to the electrode terminal of the battery is installed inside the battery chamber accommodating the battery in the portable electronic device because damage or deformation of the connection terminal may occur due to the battery being inserted in the reverse direction. .

Manufacturers of portable electronic devices display guide text or pictures on the portable electronic device to guide users in the correct battery installation direction, but users who do not understand these guides can insert the battery in the reverse direction. Often the terminal is damaged or deformed.

After the battery is inserted in the reverse direction, a connection terminal connected to the battery may be damaged and a chattering phenomenon may occur between the battery and the connection terminal even when the battery is inserted in the forward direction. Chattering refers to sudden voltage fluctuations occurring at the point of contact between the battery and the connection terminal, and the chattering involves a sudden change in the supply and interruption of current at microsecond periods. Such chattering may cause the CPU to operate abnormally, causing a whitening phenomenon in which the screen is displayed in white, a normal initialization of the CPU, or a sudden power off.

In order to fundamentally block the operation in which the battery is inserted in the reverse direction, a technique of forming a protrusion in the battery chamber and a groove corresponding to the protrusion may be used in the battery. According to this structure, the protrusion is inserted into the groove only when the battery is normally inserted into the battery chamber, and the insertion operation of the battery is blocked by the protrusion when the battery is inserted in the reverse direction.

However, in order to apply such a technique, the structure of the battery must be modified, which entails an increase in cost and a general battery cannot be adopted. In addition, since a protrusion or the like must be formed in a chamber for accommodating a battery in the portable electronic device, it may act as a limiting factor in the design of the portable electronic device.

It is an object of the present invention to provide a battery accommodating structure in which a battery is not inserted in a reverse direction in a portable electronic device.

When the battery 10 is inserted through the opening 21 of the case 20 and accommodated in the chamber 24 of the case 20, the connection terminal 22 of the case 20 is connected to the terminal portion 12 of the battery 10. By being connected to, the power of the battery 10 can be supplied to the portable electronic device.

On the other side of the case 20, the pressing pin 30 is installed to be slidable. The pressing pin 30 is installed to be movable in a direction protruding outward from the other side of the case 20.

When the battery 10 is inserted into the case 20 in the forward direction, one end 31 of the pressure pin 30 is pressed by one side surface 13 of the battery 10 to move to the outside from the other side of the case 20. Protrudes toward. When the battery 10 is inserted into the case 20 in the reverse direction, one end of the pressing pin 30 is inserted into the recess 11 of the battery 10 to maintain a stopped state with respect to the case 20.

On the other side of the case 20, the moving plate 40 is installed to be slidable. The moving plate 40 is installed to slide in a direction crossing the direction in which the battery 10 is inserted. The moving plate 40 may slide by being pressed by the pressing pin 30. The through plate 42 is formed in the moving plate 40 so that the connection terminals 22 of the case 20 are inserted into the case 20.

In order to interact with the moving plate 40 and the pressure pin 30, the inclined surface 32 is formed on the surface facing the moving plate 40 of the pressure pin 30. In addition, a portion of the movable plate 40 is bent to form a hardened portion 41. When one end 31 of the pressing pin 30 is pressed by the battery 10, the inclined surface 32 of the pressing pin 30 presses the inclined portion 41 of the moving plate 40 to move the moving plate 40. This sliding movement is performed.

The stopper 50 is installed in the other side of the case 20 so as to be movable toward the moving plate 40. The stopper 50 is inserted into the guide part 27 formed inside the case 20, and when pressed by one side surface 13 of the battery 10, the other side of the case 20 along the guide part 27. Sliding in the direction toward the outside can be moved.

The stopper 50 is provided with protrusions 51 and 52 corresponding to the through holes 42 of the moving plate 40. Therefore, depending on the position of the movable plate 40, the protrusions 51 and 52 may move through the through hole 42 by the stopper 50 moving along the guide portion 27, and the movement of the protrusions 51 and 52 may be reduced. It may be blocked by the moving plate 40.

Guide inclined surfaces 53 and 54 are formed on the protrusions 51 and 52 of the stopper 50, and guide inclined portions 43 and 44 corresponding to the guide inclined surfaces 53 and 54 are formed on the moving plate 40, respectively. do. When the movable plate 40 is slid, the guide inclined surfaces 53 and 54 of the protrusions 51 and 52 are in sliding contact with the guide inclined portions 43 and 44 of the movable plate 40, so that the stopper 50 is moved. Can move smoothly.

An elastic support 45 is formed at one end of the moving plate 40. The elastic support 45 is formed by bending one end of the movable plate 40. The support wall 28 is formed at the other side of the case 20 corresponding to the elastic support 45. The elastic support portion 45 serves to elastically support the moving plate 40 with respect to the support wall portion 28 by contacting the support wall portion 28.

Due to the configuration of the elastic support 45, the moving plate 40 is kept pressed toward the other end, and when the moving plate 40 is pressed by the pressing pin 30, the elastic support of the moving plate 40 As the 45 is compressed, the movable plate 40 can slide toward one end.

A spring 29, which is an elastic means for elastically supporting the battery 10 in the direction toward the opening 21, is disposed inside the other side of the case 20. Since the spring 29 presses the battery contained in the chamber 24 of the case 20 toward the opening 21, when the user manipulates the lever 60, the battery 10 is driven by the force of the spring 29. Protrudes out of 20.

Since the lever 60 is elastically rotated about the pivot pin 61, the user can manipulate the lever 60 when the user inserts or removes the battery 10 into the battery accommodating structure. The lever 60 functions to support the other side of the battery 10 inserted into the case 20.

The operation of the battery accommodating structure having the above-described configuration will be described below.

3 is a bottom perspective view illustrating a state before a battery is inserted into the battery accommodating structure of FIG. 1, FIG. 4 is a bottom perspective view illustrating a state in which a battery is inserted into the battery accommodating structure of FIG. 1, and FIG. 5 is FIG. 3. FIG. 6 is a partial perspective view illustrating a top view of the battery accommodating structure of FIG. 4, and FIG. 7 is a front perspective view illustrating the battery accommodating structure of FIG. 3, and FIG. 8 is a front sectional view showing a state in which the battery is inserted in the battery accommodating structure of FIG. 7 in the forward direction.

3, 5, and 7 is a state in which the movable plate 40 is elastically supported with respect to the support wall part 28 by the elastic support part 45. As shown in FIG. In this state, the pressing pin 30 is pressed by the inclined portion 41 of the moving plate 40 and inserted into the case 20. In this state, since the protrusions 51 and 52 of the stopper 50 come into contact with the moving plate 40, the movement of the stopper 50 is limited.

When the battery 10 is inserted in the forward direction through the opening 21 of the case 20, the battery 10 is accommodated in the chamber 24 as shown in FIG. 4. When the battery 10 is fully inserted into the chamber 24, the lever 60 of the case 20 rotates toward the opening 21 to support the other side of the battery 10. The battery 10 may be stably maintained inside the case 20 due to the action of the lever 60.

Insertion of the battery 10 in the forward direction means insertion in a predetermined direction to match the polarity of the terminal portion 12 formed in the battery 10, inserting in the reverse direction is inserted in a direction opposite to the predetermined direction Means that. The battery accommodating structure according to the embodiment of the present invention allows the battery 10 to be received inside the case 20 only when the battery 10 is inserted into the case 20 in the forward direction, and the battery 10 is reversed. When inserted, the battery 10 is not accommodated in the case 20.

When the battery 10 is inserted into the case 20 in the forward direction, as shown in FIG. 6, the pressing pin 30 presses the moving plate 40 so that the moving plate 40 faces the support wall 28. As far as sliding moves. The operation of each component at this time can be clearly understood through FIG.

When the battery 10 is inserted into the case 20 in the forward direction, one side 13 of the battery 10 presses one end of the pressing pin 30. Thus, the inclined surface 32 of the pressing pin 30 presses the inclined portion 41 of the moving plate 40 so that the elastic support portion 45 of the moving plate 40 is compressed toward the support wall portion 28. The moving plate 40 is slidably moved relative to the case 20 which is fixed. That is, the moving plate 40 slides by a predetermined distance toward the right side in FIG. 8.

When the movable plate 40 slides to the right, each of the protrusions 51 and 52 of the stopper 50 protrudes toward the outside of the other side of the case 20 through the through hole 42 of the movable plate 40. Can be. At this time, the guide inclined surfaces 53 and 54 of the stopper 50 slide in contact with the guide inclined portions 43 and 44 of the moving plate 40 so that the protrusions 51 and 52 pass through holes 42 of the moving plate 40. ) Can be made smoothly.

When the protrusions 51 and 52 of the stopper 50 pass through the through hole 42, the terminal portion 12 of the battery 10 is in contact with the connection terminal 22. As a result, power of the battery 10 may be supplied to the portable electronic device.

Hereinafter, the operation state when the battery 10 is inserted into the case 20 in the reverse direction.

FIG. 9 is a front cross-sectional view illustrating a state in which a battery is inserted in the battery housing structure of FIG. 8 in a reverse direction, and FIG. 10 is an operation state diagram illustrating an opening of the battery housing structure of FIG. 9.

When the battery 10 is inserted into the case 20 in the reverse direction, one of the recesses 11 in which the terminal portion 12 of the battery 10 is formed corresponds to the position of the pressing pin 30. Therefore, in FIG. 8, one side 13 of the battery 10 presses one end of the pressing pin 30, whereas in FIG. 9, one end of the pressing pin 30 is inserted into the recess 11 of the battery 10. There is no action that the pressing pin 30 is pressed toward the moving plate 40 by the battery 10.

If the pressing pin 30 is not pressed, the movable plate 40 does not move, but is elastically supported toward the left side in FIG. 9 by the elastic support 45. At this time, even if a user applies a pressing force for continuously pushing the battery 10 into the case 20, the stopper 50 pressurized by the side surface 13 of the battery 10 is moved by the moving plate 40. Is blocked. That is, since the moving plate 40 does not move, the position of the through hole 42 of the moving plate 40 does not correspond to the position of the protrusions 51 and 52 of the stopper 50. Therefore, the protrusions 51 and 52 of the stopper 30 contact the moving plate 40 to limit the movement of the stopper 50 toward the moving plate 40 of the battery 10.

As such, when the battery 10 is inserted into the case 20 in the reverse direction, the other side of the battery 10 is inserted into the case 20 as shown in FIG. 10 even if a user applies a forced force to the battery 10. It is not inserted completely. In this state, the lever 60 cannot be rotated to fix the battery 10.

In addition, since the movement of the stopper 50 is blocked by the moving plate 40 when the battery 10 is inserted in the reverse direction, the movement toward the moving plate 40 of the battery 10 is limited, so that one side of the battery 10 is provided. The surface 13 is not in contact with the connecting terminals 22. Therefore, even when the battery 10 is inserted in the reverse direction, the phenomenon that the connection terminal 22 is deformed or damaged does not occur.

FIG. 11 is a front cross-sectional view illustrating a state in which a battery is inserted into a battery accommodating structure according to another embodiment of the present invention in a forward direction, and FIG. 12 illustrates a state in which the battery is inserted in the battery accommodating structure shown in FIG. 11 in a reverse direction. It is the front section.

The battery receiving structure according to the embodiment shown in FIGS. 11 and 12 is similar in overall configuration to the battery receiving structure according to the above-described embodiment, but the pressing pin 30 is inserted when the battery 10 is inserted in the reverse direction. The configuration of the groove 111 is modified.

That is, in the embodiment shown in FIG. 9, when the battery 10 is inserted in the reverse direction, one end of the pressing pin 30 is inserted into the recess 11 in which the terminal part 12 of the battery 10 is disposed. In contrast, in the battery accommodating structure according to the embodiment shown in FIGS. 11 and 12, when the battery 10 is inserted in the reverse direction, the pressing pin 30 is inserted into a separate recess 111 in which the terminal part 12 is not disposed. One end is inserted, the pressing pin 30 maintains a stationary state with respect to the case (20).

As shown in FIG. 11, when the battery 10 is inserted in the forward direction, one end of the pressing pin 30 is pressed by one side surface 13 of the battery 10. Thus, the moving plate 40 slides by the pressing pin 30, and the protrusion of the stopper 50 passes through the through hole of the moving plate 40. As a result, the battery 10 may move toward the moving plate 40, so that the terminal portion 12 and the connection terminal 22 of the battery 10 are connected.

As shown in FIG. 12, when one end of the pressing pin 30 is inserted into the recess 111 of the battery 10 when the battery 10 is inserted in the reverse direction, the pressing pin 30 stops with respect to the case 20. The moving plate 40 is not pressurized while maintaining the closed state. The moving plate 40 is elastically supported toward the left side in FIG. 12 with respect to the support wall portion 28 due to the action of the elastic support portion 45. Since the stopper 50 is blocked by the moving plate 40, the movement of the battery 10 that presses the rear of the stopper 50 is also limited. Therefore, even if a user applies a forcible force to the battery 10 in this state, the battery 10 can no longer move so that the terminal portion 12 and the connection terminal 22 of the battery 10 do not contact each other.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the appended claims.

The battery accommodating structure of the present invention as described above has a stopper that is fixed when the battery is inserted in the reverse direction and blocks the insertion of the battery, so that the battery is not inserted in the reverse direction.

In addition, even if a user applies a force to insert the battery in the reverse direction, the movement of the battery is limited by the stopper, so that the connection terminal of the portable electronic device connected to the battery is not damaged or deformed.

In addition, the battery accommodating structure of the present invention can prevent damage and deformation of the connection terminal due to reverse insertion of the battery without significantly modifying the shape of the chamber and the battery accommodating the battery, and thus can accommodate a standard battery.
