Description of the Invention: [Technical Field] 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. [Prior Art] Portable electronic devices such as mobile phones and personal digital assistants (PDAs) have a wide range of applications, and such portable electronic devices use batteries as their energy source. Such batteries are typically installed in a portable electronic device by means of a battery cover that is plugged into the body of the portable electronic device to provide electrical energy thereto. In the use of portable electronic devices, it is often necessary to replace the battery of the portable electronic device. The battery cover of the conventional portable electronic device generally needs to be easily disassembled and assembled to replace the battery. The battery cover of the conventional mobile phone is generally in the shape of a cover, and includes a main body, an end portion, two side walls, and a bottom wall. The main sheet body has a substantially rectangular plate shape, and the two side walls and a bottom wall are respectively bent by the edge of the main sheet body. Both ends of the bottom wall are respectively connected to the two side walls. The bottom wall is provided with two hooks for engaging with the recesses of the mobile phone body; and the end of the battery cover opposite to the bottom wall extends: a card block for engaging with the body slot of the mobile phone. When arranging, first align the end and the two side walls of the battery cover with the mobile phone body, the second card is aligned with the card slot of the body, and then push the battery cover toward the two blocks, and one of the covers is stuck in the card. In the slot, the side wall is attached to the peripheral wall of the mobile phone body, and the two hooks of the bottom wall of the battery cover are engaged in the recess of the body. Requires 8 201016982 When removing the battery cover, push the battery cover and reverse the above steps. : However, although this kind of structure can realize the function of disassembling and assembling the battery cover at any time, the battery cover and the body are relatively slippery when the battery cover is attached to the body after the battery cover is attached to the body. The lock is not stable enough. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a battery cover locking mechanism that is securely locked and simple in structure. A battery cover locking mechanism for locking a battery cover to a housing, comprising a first mounting portion disposed on the body, a second mounting portion disposed on the battery cover, an elastic body and an operating member.

The second open end 2111 of the accommodating groove 211 and the first open end 1201 of the first accommodating groove 120 on the first mounting portion 12 form a space. In addition, the pressing operation member 15 is provided with the end of the clamping portion 151. The ring portion 140 of the elastic body 14 is biased toward the abutting end 141 with respect to the elastic end 142, so that the buckle 152 end of the operating member 15 is away from the protrusion. 1231 is in the open state. Finally, the operating member 15 is released, and the elastic restoring force of the elastic end 142 of the elastic body 14 abuts against the opposite end of the operating member 15 and the buckle 152 in a direction away from the first receiving groove 12, so that the buckle 152 is pressed downward. Therefore, it is fastened to the engaging block 212. At this time, the protrusion 1231 of the second resisting block 123 is abutted between the hinged end 153 of the operating member 15 and the buckle 152, and the elastic force of the elastic body 14 is blocked to maintain the operating member 15 in a balanced state. Thus, the operating member 14 is placed in the space formed by the second mounting portion 21 and the first mounting portion 12 and the battery cover 20 is locked to the housing 10. 14 201016982 Operation t and main body 1Fig. 5 'When the battery cover 20 is opened, the elastic end 142 of the body 14 is pressed close to the abutment... the operating member 5 is rotated by the shaft ί3; the card of the operating member 15 Buckle 152 out of the second battery ^ From? The block 212 of the second mounting portion 21 is unlocked. This is unlocked from the housing 10. Finally, the battery cover 2〇 is slid toward the bottom wall of the casing 20 so that the two bumps 205 of the battery cover 2 are slid out from the two slots 107 of the casing 1 and the bottom end wall 2 of the battery cover 2 The upper two jaws 206 slide out of the two engaging recesses 1 〇 9 of the housing 1 to obtain the battery cover 20. It can be understood that the hinge shaft 13 and the two clamping blocks 122 can be made of an elastic material, and can be appropriately deformed and restored during assembly. In the embodiment, the hinge shaft 13 and the two clamping blocks 1220 are easily assembled. The battery cover locking mechanism is rotatably mounted on the housing 1 and the battery cover operating member 15 by opening or closing the engagement with the hinge shaft 13 to realize the battery cover 20 and the housing 1 Open and lock on. The battery cover locking mechanism can prevent the cover body from sliding relative to the body in the direction in which the body is mounted, and has a simple structure and convenient operation.
