Battery cover locking mechanism

The present invention relates to a battery cover locking mechanism, and more particularly to a battery cover locking mechanism for 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 such portable electronic devices use batteries as their energy source. Such batteries are typically installed in a portable electronic device by a battery cover that is inserted into the body of the portable electronic device housing to provide electrical energy thereto. During the use of the portable electronic device, it is often necessary to replace the battery of the portable electronic device. Therefore, the battery cover of the conventional portable electronic device generally needs to be easily disassembled and assembled to replace the battery. The battery cover latch structure of the portable electronic device is generally fastened to the body by using a hook and a buckle structure, that is, a hook and a lock pin are arranged on the battery cover, and a card slot and a buckle are arranged on the housing. The keyhole is used to 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. The battery cover is easy to operate when disassembling and assembling, but has many components and high manufacturing cost.

In view of this, it is necessary to provide a battery cover locking mechanism with fewer components and convenient operation. A battery cover locking mechanism includes a housing, a battery cover covering the housing, at least one hook disposed on the housing, at least one clamping hole disposed on the battery cover, and rotatably mounted on the battery An operating button of the cover, the operating button is provided with at least one curved end, and the hook is locked in the holding hole to lock the battery cover on the housing, and the rotating operation button rotates relative to the battery cover, so that The curved end pushes the hook to unlock relative to the latching hole. Compared with the prior art, the battery cover locking mechanism realizes the locking of the battery cover and the casing by the card provided on the casing and the holding hole provided in the battery cover, and is rotatably mounted on the battery. The hook of the cover body pushes against the hook provided on the casing to realize opening of the battery cover and the casing. The battery cover locking mechanism has fewer components and is convenient to operate.

A cylindrical protrusion 231 is protruded from the bottom wall (not shown) of the groove of the mounting groove 23. The projections 231 are adjacent and located below the opening 22. A first circular hole 232 is recessed in the protrusion 231. The mounting groove 23 and the slot sidewall (not labeled) opposite to the opening 22 extend a stop 234 toward the opening 22 . The stopper 234 is offset from the card slot 221 and spaced apart from the projection 231 by a certain interval. The shape and size of the fixing plate 24 are substantially equal to the notches of the mounting groove 23, and can be covered on the mounting groove 23 to close the notch. The fixing plate 24 is recessed with a second circular hole 241 corresponding to the first circular hole 232 of the protrusion 231. The fixing plate 24 further defines two through-hole rectangular locking holes 26 corresponding to the two hooks 15 on the casing 10. The operation key 30 includes a cam-shaped body 31, two curved ends 32, two thrust blocks 33, a first shaft body 35 and a second shaft body 36. The sheet body 31 is provided with two opposing surfaces 310. The two curved ends 32 are opposite ends of the sheet body 31 and are connected to the two surfaces 310. A portion of the curved end portion 32 is provided with a plurality of tooth portions 321 for increasing the operation of the operation keys 30. The friction between the human hand and the operation key 30. The two abutting blocks 33 are respectively formed by extending from the two arcuate ends 32 away from the sheet body 31, and the two abutting blocks 33 are staggered. The first shaft body 35 and the second shaft body 36 are cylindrical and protruded from the two surfaces 310 respectively, and are located at the center of the sheet body 31 and aligned vertically. As shown in FIG. 3 , the operation key 30 is first mounted in the mounting slot 23 , and the second shaft 36 of the operation key 30 is rotatably mounted in the first circular hole 232 of the battery cover 20 . The resisting block 33 is in contact with the stopper 234; the operating button 30 has the curved end 32 of the tooth portion 321 exposed from the opening 22 to the outside of the battery cover 20; and the fixing plate 24 is covered in the mounting slot The first shaft body 35 is rotatably mounted in the second circular hole 241. When the battery cover 20 is mounted on the housing 10, the two hooks 15 pass through the two latching holes 26, and the hook portion 151 is engaged in the latching hole 26. At this time, the operation button 30 The two hooks 15 are located between the two hooks 15 and the hook portions 151 are respectively abutted against the two curved ends 32. The two resisting blocks 33 are respectively abutted against the stoppers 234 and the card slots 221, so that the battery cover 20 is locked. On the housing 10. Referring to FIG. 4, when the battery cover 20 is opened, the arcuate end 32 of the operation key 30 is provided with the toothed portion 321 so that the operation key 30 is provided by the first shaft body 35 and the second shaft. The body 36 is rotated such that the arcuate end 32 abuts against the hook portion 151 of the second hook 15 to be unlocked, thereby unlocking the latching hole 26, thereby opening the battery cover 20. The housing 10 of the battery cover locking mechanism is locked by the hook 15 and the battery cover 20, and the battery cover 20 and the housing 10 are opened by rotating the operation key 30 provided with the pressing block 33. .
