Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a fixed charger having an anti-theft function according to the present invention.

As shown in FIG. 1, the stationary charger has an accommodating groove 12 on an upper surface of the charger main body 10, and a connector 14 is installed at the bottom of the accommodating groove 12, and the accommodating groove 12 is provided. Both sides of the) have a configuration in which the opening hole 16 is formed.

The mobile communication terminal in which the battery 22 is mounted on the main body 20 is seated in the receiving groove 12 of the charger main body 10 and connected to the connector 14 to perform charging.

Locking grooves 24 are formed at both sides of the terminal body 20, and locking pieces 32 are provided in both opening holes 16 of the charger main body 10 so as to be accessible. The locking piece 32 is inserted into the locking groove 24 of the terminal body 10 when the mobile communication terminal is seated in the receiving groove 12 of the charger body 10 by the driving device 100. The mobile communication terminal can be separated from the charger main body 10 by being locked (locked) to prevent the terminal body 20 from being separated or released in the locked state (locked).

In FIG. 1, the member number '18' is an 'input key part'. As described later, the input key unit 18 is driven by inputting a password to release the locking piece 32 that is locked (locked) while being inserted into the locking groove 24 of the terminal body 20. For controlling the device 100.

2 and 3 show a detailed embodiment of the above-described driving device 100 as a structure inside the charger according to the present invention.

As shown in Figures 2 and 3, in a specific embodiment of the present invention, the drive device 100 includes a locking arm 30 which is installed on both sides of the inside of the charger body (10). One end of the locking arm 30 is provided with the engaging piece 32 described above.

The locking arm 30 is pivotally installed at an intermediate portion thereof by a hinge shaft 34. As the locking arm 30 rotates about the hinge shaft 34, a locking piece 32 provided at one end thereof is charged to the charger. It enters and exits through the opening hole 16 of the main body 10. Therefore, the locking piece 32 is locked or released in a state where the locking piece 32 is inserted into the locking groove 24 of the terminal body 20 as the locking arm 30 is restrained or released.

In a preferred embodiment of the present invention, the slide arm 40 is connected to the other end of the locking arm 30 described above. The slide arm 40 is installed to enable left and right linear motion, and the locking arm 30 is rotated by the linear motion thereof. Accordingly, the locking arm 30 is restrained or released by restraining or releasing the slide arm 40, and the locking piece 32 is restrained or released in accordance with the restraint or release of the locking arm 30.

Specifically, a protruding pin 42 is formed at an end of the slide arm 40, and a long groove 36 is formed at the locking arm 30, so that the protruding pin 42 is formed at the long groove 36. It has a structure that allows sliding movement. Therefore, when the slide arm 40 is linearly moved left and right, the pivoting pin 42 of the slide arm 40 slides along the long groove 36 to rotate the locking arm 30. It becomes possible. Here, the locking arm 30 is supported by the elastic member 50, the force to rotate in the direction in which the hook 32 formed at one end thereof protrudes into the opening hole 16 of the charger body 10 Receive.

In the present invention as described above, the hook 32 of the locking arm 30 is inserted into the opening hole 16 of the charger body 10 is inserted into both locking grooves 24 of the terminal body 20 When the slide arm 40 is restrained from linear movement, the locking arm 30 is locked so as not to rotate. The inability to rotate the locking arm 30 means that the hook 32 of the locking arm 30 cannot move while being inserted into the locking groove 24 of the terminal body 20 so that the terminal body 20 is locked. Means that.

In the embodiment shown in the figure, as the restraining and releasing means for restraining or releasing the slide arm 40, the restraining lever 60 restraining the slide arm 40 and the restraining lever 60 are used. An actuator 70 for operating is included. More specifically, a locking groove 44 is formed at the end of the slide arm 40, and a locking protrusion 62 is inserted into the locking groove 44 at the end of the restraining lever 60. Therefore, the locking projection 62 is inserted into or removed from the locking groove 44 of the slide arm 40 by the up and down linear reciprocating motion of the restraining lever 60 by the actuator 70. The slide arm 40 is thereby locked or released.

In a preferred embodiment of the present invention, an electromagnet is used as the actuator 70. The actuator 70 made of the electromagnet is provided to face the end of the restraint lever 60. Therefore, when a current is supplied to the actuator 70, an electromagnet is magnetized, and the locking projection 62 of the restraining lever 60 is pulled by pulling the restraining lever 60 toward the slide arm 40 by its magnetic force. It is configured to be inserted into the locking groove 44 of the slide arm 40. Here, the restraining lever 60 may be made of a magnetic body so that a magnetic force acts. Otherwise, the end of the restraint lever 60 may be provided with a permanent magnet 64 or magnetic material. In addition, a return spring 80 is connected to the restraint lever 60. The return spring 80 provides a biasing force that attempts to move the restraint lever 60 to the opposite side of the slide arm 40. Therefore, to release the restraint of the slide arm 40, when the current flowing through the actuator 70 is blocked, the restraining lever 60 is moved from the slide arm 40 by the elastic force of the return spring 80. Pulled in the direction of departure.

In a preferred embodiment of the present invention, the interruption of the current flowing through the actuator 70 is performed by a control device including a control module 90.

When the mobile communication terminal is seated on the charger main body 10, the control module 90 locks the seated terminal by applying a current to the actuator 70. When the mobile communication terminal is seated on the charger main body 10, the connector 14 of the charger main body 10 is electrically connected to the battery of the terminal, thereby recognizing that current flows from the charger to the terminal side. . In this case, the control module 90, when the mobile communication terminal is seated in the charger main body 10 and the current flows in the battery of the mobile communication terminal, it is programmed to recognize the current and apply the current to the actuator 70. Can be set.

Then, the unlocked terminal is released by cutting off the current applied to the actuator 70. In a preferred embodiment of the present invention, it is preferable that the interruption of the current supplied to the actuator 70 is performed by the terminal user inputting the password by the password input means. The input of the password may be operated by the input key unit 18 provided in the charger main body 10 or by using an input key of the mobile communication terminal 20.

Therefore, when the actuator 70 is operated by the control module 90, when the mobile communication terminal is seated in the charger main body 10 and current flows in the battery of the terminal, the actuator 70 recognizes this. This can be realized by applying a current to the mobile terminal or checking the password when the password is input from the mobile communication terminal or the input key unit 18, and setting the program in advance to cut off the current applied to the actuator 70.

4 is a view illustrating a locking mechanism freely moving before mounting the mobile communication terminal to the charger. That is, in the state where the terminal is not installed in the charger main body 10, since the electric current is not applied to the actuator 70, an electromagnet is not magnetized. Therefore, the restraining lever 60 is pulled in the direction away from the slide arm 40 by the return spring 80, so that the engaging projection 62 of the restraining lever 60 is engaged with the engaging groove (of the slide arm 40). The slide arm 40 is freed from 44. Therefore, the slide arm 40 is free to move left and right linearly. In this way, as the slide arm 40 is free to move linearly, the locking arm 30 can also be freely rotated. By the way, the locking arm 30 maintains a state in which the locking piece 32 formed at one end thereof by the elastic member 50 is pulled into the opening hole 16 of the charger main body 10. Therefore, while the terminal body 20 is mounted in the receiving groove 12 of the charger main body 10, the battery 22 and the terminal main body 20 side of the terminal push the locking piece 32 outward. As a result, the locking arm 30 overcomes the elastic force of the elastic member 50 and rotates outward, thereby allowing the terminal to be mounted in the receiving groove 12 of the charger body 10.

As described above, when the terminal main body 20 is completely mounted in the receiving groove 12 of the charger main body 10, as shown in FIG. 5 (or FIG. 3), the locking of the terminal main body 20. The groove 24 and the locking piece 32 of the locking arm 30 coincide with each other. At this time, since the locking arm 30 is pulled by the elastic member 50, the locking piece 32 of the locking arm 30 is inserted into the locking groove 24 of the terminal body 20. Thus, the terminal body 20 is supported by the elastic force of the elastic member 50.

As such, when the terminal main body 20 is completely mounted in the charger main body 10, a current is supplied to the battery 22 to perform charging. At the same time, when a current is applied to the actuator 70 by the control module 90, the actuator 70 is magnetized, and the restraint lever 60 is pulled by the magnetic force. When the restraint lever 60 is pulled, the engaging protrusion 62 of the restraint lever 60 is inserted into the engaging groove 44 of the slide arm 40, so that the slide arm 40 cannot move left and right. Locked. When the slide arm 40 is locked, since the protruding pin 42 of the slide arm 40 is coupled to the long groove 36 of the locking arm 30, the locking arm 30 can also be rotated. There will be no. When the locking arm 30 cannot be rotated, the locking piece 32 of the locking arm 30 cannot move while being inserted into the locking groove 24 of the terminal body 20, so that the terminal body 20 is locked. do.

As shown in FIG. 6, when the battery 22 is charged and then the terminal is disconnected from the charger, when the current applied to the actuator 70 is blocked, the magnetic force of the actuator 70 is lost. When the magnetic force of the actuator 70 is lost, since the force for pulling the restraint lever 60 is removed, the restraint lever 60 is moved back to its original position by the return spring 80. When the restraining lever 60 moves to the original position, the restraining protrusion 62 of the restraining lever 60 is separated from the catching groove 44 of the slide arm 40, thereby releasing the restraint of the slide arm 40. Accordingly, the restraint of the locking arm 30 is also released. Therefore, when the terminal is lifted from the charger main body 10, the locking piece 32 of the locking arm 30 is pushed outward by the lifting force and is released from the locking groove 24 of the terminal main body 20.

Figure 7 is a flow chart for the preferred process of controlling the current applied to the actuator 70 which is the electromagnet in the stationary charger according to the present invention.

As described above, locking and releasing of the terminal are performed by interrupting a current applied to the actuator 70, and the interruption of the current is performed by the terminal being mounted in the charger, and from the input key 18 or the terminal of the charger. This can be done as a password is entered.

That is, as shown in FIG. 7, when it is confirmed that the mobile communication terminal is mounted on the charger main body 10 (step 201), current is applied to the actuator 70 which is an electromagnet (202) to lock the terminal to the charger main body 10. Let's do it. When the terminal is seated on the charger main body 10, current is supplied to the battery 22 side, so whether the terminal is mounted on the charger main body 10 can be confirmed by recognizing whether or not the current is supplied to the battery 22 side. have.

After the charging is performed, if a password is input from the terminal or the input key 18 (step 203), it is checked whether the input password matches the password set in advance (step 204) and matches the password set in advance. By blocking the current applied to the actuator 70 which is the electromagnet (step 205), the locked state of the terminal is released.

In the foregoing description, specific embodiments of the present invention shown in the accompanying drawings have been described in detail, but this is only an example and the protection scope of the present invention is not limited thereto. In addition, the embodiments of the present invention as described above can be variously modified and equivalent other embodiments by those of ordinary skill in the art within the technical spirit of the present invention, such modifications and equivalent other embodiments are It goes without saying that it belongs to the appended claims of the invention.

As described above, the present invention can lock the mobile communication terminal while it is mounted in the charger, thereby preventing the mobile communication terminal from being stolen or randomly detached from the charger against the user's intention.
