Battery cover lock structure

The invention relates to a battery cover latch structure, in particular to a battery cover latch structure applied to a portable electronic device such as a mobile phone.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used, and batteries that provide energy for portable electronic devices need to be replaced as energy is consumed. In order to make it easy to open the battery cover that is fastened to the battery when the battery is replaced, many battery cover latch structures have been designed.

The battery cover latch structure of the conventional portable electronic device is mostly clamped on the body by using a hook and a buckle structure, that is, a hook and a lock pin are arranged on the battery cover, corresponding to the card slot and the buckle on the housing. a hole to thereby secure the battery cover to the housing. The battery cover is tightly and firmly combined with the housing after installation, but it is laborious and inconvenient to disassemble. Another battery cover latch structure is provided with an ejector device, a button and an elastic component, and the button is provided with a latching portion, the elastic component is resisted between the button and the body, and the latching portion is slid on the body by the button and the battery The latching member is engaged or disengaged, and the ejector device is disposed between the body and the battery cover for ejecting the battery cover, and the elastic member of the elastic member is mostly a spring or a spring. This type of battery cover is easy to operate when disassembled, but the rebound mechanism takes up a relatively large space. Especially for small portable electronic devices, it is difficult to guarantee the card lock The structure has sufficient travel space and a rebound mechanism.

In view of this, it is necessary to provide a battery cover latch structure that occupies less space.

A battery cover latch structure for detachably mounting a battery cover on a casing, the battery cover latch structure comprising a button, a mounting portion disposed on the casing, and a hook disposed on the battery cover And an elastic body, the button comprises a mounting protrusion, the mounting protrusion is provided with a through hole penetrating the mounting protrusion and a post, the mounting part comprises a button hole for accommodating the button and setting a clamping block on opposite sides of the button hole; the elastic body passes through the through hole of the mounting protrusion and the two ends thereof are respectively clamped on the holding block of the mounting portion; the button slides on the housing The hook of the battery cover and the post of the button are locked or unlocked.

Compared with the prior art, the battery cover latch structure locks or unlocks the battery cover and the housing by engaging the button of the button with the card member of the battery cover by the sliding of the button and the housing. In addition, the elastic body of the battery cover latch structure passes through the mounting protrusion of the button and is clamped to the holding block of the mounting portion. The battery cover latch has fewer structural components, and the relatively small occupied space, and the battery cover structure is relatively simple to operate when opened and closed.

The blocks 1113, 1114 are between the inner wall of the top wall 111.

Referring to FIG. 7 and FIG. 8 together, when the button 15 is assembled to the housing 11, the elastic body 17 is first passed through the through hole 1547 and the recess 1548 of the button 15. The button 15 with the elastic body 17 is then received in the button hole 1111 of the mounting portion 112 by the inside of the top wall 111. The pressing surface 1511 of the button 15 passes through the button hole 1111 to expose the casing 11. The bottom surface 1533 of the mounting protrusion 153 of the button 15 abuts against the second holding strip 1116 of the mounting portion 112, and the opening of the counterbore 1543 on the bottom surface 1533 is in communication with the notch 1112 of the mounting portion 112. The connecting portion 1522 and the extending portion 1524 of the resisting rib 152 of the button 15 abut against the first holding strip 1115 of the mounting portion 112. The two ends of the elastic body 17 are respectively accommodated in the gaps 1117, 1118 and are clamped on the top surfaces of the two holding blocks 1113, 1114 and the housing 11. Between the inner walls of 111. The two lugs 155 of the button 15 are respectively clamped on the bottom of the holding block 1113 and the card slot 1119. That is, the assembly of the button 15 and the housing 11 is completed.

When the battery cover 13 is to be placed on the housing 11, the battery cover 13 is mounted on the mating portion 121 of the housing 11, wherein the main body 131 and the top end portion 133 of the battery cover 13 are The third side wall 135 and the fourth side wall 137 are respectively disposed on the panel 110, the top wall 111, the first side wall 114 and the second side wall 115 of the housing 11, and the battery cover 13 and the top end 131 are opposite to each other at the end. On the support portion 120 of the body 11. The battery cover 13 hook member 134 passes through the notch 1112, and the hook portion 1341 and the post 1545 of the button 15 latch the button hole, so that the battery cover 13 is fastened to the housing 11.

As shown in FIG. 9, when the battery cover 13 is to be opened, the pressing portion 151 of the button 15 is pressed to cause the button 15 to move the elastic body 17 to the inside of the casing 11, so that the hook portion 1341 of the battery cover 13 and the button 15 are stuck. The column 1545 is unlocked, at which time the battery cover 13 and the housing 11 are locked and unlocked. In addition, the holding blocks 1113 and 1114 give the elastic body 17 a force opposite to the direction in which the button 15 moves, and the through hole 1547 serves as a fulcrum of the elastic body 17 to bend the elastic body 17. The restoring force generated by the elastic deformation of the elastic body 17 acts on the button 15 to return to the initial position. The user can remove the battery cover 13 from the housing 11 with a finger.

The battery cover latch structure engages the latch 1548 of the button 15 with the hook portion 1341 of the battery cover 13 by the button 15 and the fixed button 15 in the elastic body 17 of the housing 11, thereby clamping the battery cover 13 When the casing 11 is detached, the pressing portion 151 of the button 15 is pressed to cause the button 15 to move the elastic body 17 to the inside of the casing 11, so that the hook portion 1341 of the battery cover 13 is disengaged from the post 1545 of the button 15. The battery cover 13 is locked with the housing 11 to be unlocked.
