Battery cover lock structure

The present invention relates to a battery cover latch structure, and more particularly 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 have to be replaced with energy consumption, so that the battery can be easily installed. 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 pair of hooks are arranged at one end of the battery cover, and a latch pin is disposed at the other end, corresponding to one end of the body. One pair of card slots, and the other end is provided with a buttonhole. When installing, first insert the hook of the battery cover into the card slot of the body, and then rotate the battery cover with the card slot as the axis toward the body and press the battery cover until the card lock pin of the battery cover is locked into the lock hole of the body. .

Although the battery cover is tightly and firmly combined with the body after installation, the disassembly and assembly is laborious, the operation is inconvenient, and the excessive force may damage the battery cover, and even in a serious case, the damage of the portable electronic device may be caused.

In view of this, it is necessary to provide a battery cover latch structure that is easy to operate.

A battery cover latch structure includes a body, a battery cover, a button and a reset member, the electric The battery cover has a latching member, and the button is provided with a claw. The resetting member comprises two pieces, each of the plurality of sheets comprises a latching portion and a connecting portion perpendicularly connected to the latching portion, the card The holding portion is fixed on the body, and the connecting portion is embedded in the button, so that the claw can be detachably engaged with the locking member.

Compared with the prior art, the battery cover latch structure of the present invention provides an elastic force and a restoring force to the button by the resetting member, and the jaw is separated from the latching member by simply pressing the button when the battery cover is disassembled. In order to achieve the purpose of unlocking, the operation is relatively labor-saving.

The invention discloses a battery cover latch structure, which is applied to a portable electronic device such as a mobile phone. In the preferred embodiment, a mobile phone is taken as an example for description.

Referring to FIG. 1 and FIG. 2 , the battery cover latch structure 10 of the present invention includes a body 11 , a battery cover 12 , a button 13 and a reset piece 14 .

The body 11 has a top wall 111 , a bottom wall 112 opposite to the top wall 111 , and a left side wall 113 and a right side wall 114 connecting the top wall 111 and the bottom wall 112 . The top wall 111, the bottom wall 112, the left side wall 113, and the right side wall 114 define a rectangular receiving groove 115 for accommodating the battery of the mobile phone ( The figure is not shown) and electronic components such as circuit boards (not shown). A rectangular notch 116 is defined in the bottom wall 112. The notch 116 is in communication with the receiving groove 115. Two positioning posts 118 are protruded from the body 11 adjacent to the notch 116.

The battery cover 12 is used to cover the receiving slot 115 of the body 11 to shield the battery. The battery cover 12 has a substantially rectangular sheet shape and has a bottom wall 121 and a peripheral wall 122 bent from a periphery of the bottom wall 121. A snap member 124 protrudes from a side of the short side of the bottom wall 121 of the battery cover 12 . The latching member 124 includes an arm portion 1242 and an extending portion 1244. The arm portion 1242 is substantially a rectangular body. The extending portion 1244 extends perpendicularly from one end of the arm portion 1242. A surface of the extending portion 1244 defines a rectangular opening 1246.

The button 13 includes a pressing portion 131 and a claw 132. The pressing portion 131 has a substantially stepped plate shape and has a pressing surface 1311 and an opposite bottom surface 1312. The pressing portion 131 has a flange 1314 on the circumferential side thereof. The claw 132 is substantially in the shape of an "L", and is protruded from the bottom surface 1312. A hook 134 extends perpendicularly from the end of the claw 132. The claw 132 has elasticity for being caught on the clip 124 of the battery cover 12.

The reset member 14 includes a two-piece body 16 and a connecting piece 19. Each of the bodies 16 includes a latching portion 162 , a connecting portion 163 and a resilient piece 164 . The holding portion 162 has a rectangular sheet shape and a through hole 1628 is formed in the surface thereof. The connecting portion 163 extends vertically from one end of the latching portion 162. The engaging portion 162 and the connecting portion 163 form a curved corner 1626. The corner 1626 can be elastically deformed by an external force, and can be restored to its original state after the external force is removed. The elastic piece 164 extends from one end of the connecting portion 163 and is bent into a substantially "L" shape. The elastic piece 164 includes a first folded edge 1642 and a second folded edge 1644 extending perpendicularly from the first folded edge 1642. The connecting pieces 19 are vertically connected to the two bodies 16 to constitute the resetting member 14. Referring to FIG. 3, the reset member 14 has the connecting piece 19, the connecting portion 163 and the first folded edge 1642 embedded in the button 13 by insert molding.

Please refer to FIG. 4 and FIG. 5 together. When assembling, the resetting member 14 is firstly passed through the through hole 1628 and the two positioning posts. The button 118 is fixed to the body 11 and the pressing portion 131 of the button 13 is received on the notch 116. At this time, the restoring member 14 presets an elastic force so that the flange 1314 of the button 13 is tightly pressed against the inner side of the bottom wall 112 of the body 11, so that the battery cover latching structure 10 is installed.

When the battery cover 12 is to be placed on the body 11, the battery cover 12 is first aligned with the receiving slot 115, and the battery cover 12 is pressed to pass the hook 134 through the rectangular opening 1246 and resist the On the surface of the extension 1244. At this time, the second flange 1644 of the elastic piece 164 abuts against one end of the extending portion 1244.

Referring to FIG. 6 , when the battery cover 12 is to be opened, only the pressing surface 1311 of the button 13 is pressed to move the button 13 in the direction of the receiving groove 115 against the elastic force of the resetting member 14 . At the same time, the second flange 1644 of the elastic piece 164, the locking portion 162 and the corner 1626 between the connecting portion 163 are elastically deformed until the hook 134 is disengaged from the rectangular opening 1246 to open the battery cover 12. At this time, the button 13 is released, and the button 13 is returned to the initial state.

It can be understood that the elastic piece 164 can be omitted, and the force for the button 13 to return to the initial state is provided by the elastic deformation force generated between the catching portion 162 and the connecting portion 163.

The battery cover latch structure 10 of the present invention provides an elastic force and a restoring force to the button 13 by the resetting member 14. When the battery cover is disassembled, the button 13 can be pressed to separate the claw from the latching member. Reach the purpose of unlocking.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
