Description

Technical Field

[0001] The utility model relates to the technical field of battery cover disassembly and assembly, in particular to an installation structure of a battery cover. Background Art

[0002] In daily life, using button batteries to power electronic devices is a relatively common power supply method. When the electronic device runs out of power, the battery cover can be opened to replace the button battery inside.

[0003] Chinese Patent No. 201320177928.8 discloses a battery cover for a remote control, including a body. The body is plate-shaped, one end of the body is warped inward to form a warped edge, an insertion block is provided on the back of the warped edge, the insertion block is integrally formed with the body, and a circular arc-shaped notch is provided at the front edge of the other end of the body, and three convex ribs with different lengths are provided above the circular arc-shaped notch.

[0004] For dust prevention and aesthetics, after the battery cover slides to cover and be snap-fitted and limited with the housing, it is completely attached to the housing, lacking a force application point, making it difficult to remove the battery cover. In the above solution, a circular arc-shaped notch and convex ribs are provided to increase the force application points on the battery cover, facilitating driving the battery cover to slide to release the snap connection with the housing and opening the battery cover.

[0005] However, for the opening method of the battery cover in a detachable button battery, there are specific standards in the CE certification, and two independent and combined actions are required to open the battery cover to ensure the safety of use. However, in the above solution, the battery cover can be opened only by applying force on the convex ribs or the circular arc-shaped notch to drive the battery cover to slide and release the snap connection, which does not meet the safety standards. Summary of the Utility Model

[0006] Aiming at the disadvantage that the battery cover can be directly opened by a single step of applying force on the convex ribs or the circular arc-shaped notch to drive the battery cover to slide and release the snap connection in the prior art, with relatively low safety, the utility model provides an installation structure of a battery cover.

[0007] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0008] An installation structure of a battery cover, including a housing provided with a battery cavity, and a battery cover detachably snap-fitted on the housing and closing the battery cavity after snap-fitting. After the battery cover is snap-fitted with the housing, the contact surfaces of the two are attached, and there is a buckle groove between the two to facilitate separating the two. An occlusion member that can be inserted into or detached from the buckle groove elastically extends on the housing, and when the occlusion member is inserted into the buckle groove, the occlusion member completely occludes the side of the buckle groove located outside the outer wall of the battery cover.

[0009] With the above solution, since the contact surface between the battery cover and the shell is fitted, and the battery cover itself is relatively thin and has a smooth surface, it is difficult to apply force. Therefore, the buckle groove is used as a force application point to apply external force to release the clamping connection between the battery cover and the shell, so as to separate the two. When the buckle groove is located on one side of the outer wall of the battery cover and is completely blocked by the shielding member, there is no force application point on the battery cover, making it difficult to open the battery cover. When removing the battery cover, it is necessary to first cause the shielding member to elastically retract to expose the buckle groove as a force application point, and then apply force on the buckle groove to drive the battery cover away from the shell to release the clamping connection with the shell. The removal of the battery cover can only be achieved by exposing the force application point and driving the battery cover to move upward, two independent and combined actions, to ensure safety and meet the standards in CE certification.

[0010] Preferably, a boss is provided on the upper end surface of the shell, a groove for inserting the boss is provided on the side of the battery cover close to the shell, the shielding member is elastically extended horizontally on the outer wall of the boss, and a buckle groove is provided on the battery cover and connected to the groove.

[0011] By adopting the above scheme, a boss is provided, and the size of the boss is smaller than the shell. When the battery cover is closed on the boss so that its bottom surface is in contact with the upper end surface of the shell, there is still a part of the upper end surface of the shell that is not blocked by the battery cover as the force point of the shell, which makes it easier to open the battery cover. That is, when opening the battery cover, the buckle groove is first exposed as the force point of the battery cover, and the upper end surface of the shell is used as the force point on the shell. Applying force to both of them facilitates the separation of the battery cover and the shell.

[0012] Preferably, a spring sheet fixedly connected to the shielding member and the boss is provided between the shielding member and the boss. As the spring sheet is compressed or reset, the shielding member is completely separated from or inserted into the buckle groove and completely covers the buckle groove on one side of the outer wall of the battery cover.

[0013] By adopting the above scheme, a flat tool is used to apply external force to the shielding member to drive it to retract until the buckle groove is exposed, and the spring sheet deforms to generate elastic force; when the external force is removed, under the action of the resetting elastic force of the spring sheet, the shielding member extends out and is inserted into the buckle groove, completely covering the buckle groove located on one side of the outer wall of the battery cover.

[0014] Preferably, a buckling structure is provided between the boss and the battery cover, and the buckling structure comprises a card slot recessed on the outer side wall of the boss and a card block protruding on the inner side wall of the groove and capable of being inserted into or detached from the card slot.

[0015] With the above solution, the card block is inserted into the card slot for clamping and limiting after being squeezed and slid with the boss. When the battery cover is opened, sufficient external force can be applied to drive the card block to be squeezed and slid with the card slot and then detach from the card slot.

[0016] Preferably, the upper end surface of the boss is provided with a first extrusion inclined surface that is extrusion-slidably engaged with the clamping block when the battery cover is closed. The upper end surface of the clamping block is provided with a second extrusion inclined surface that is extrusion-slidably engaged with the card slot when the battery cover is disassembled. The card slot is provided with a mating inclined surface that cooperates with the second extrusion inclined surface.

[0017] With the above solution, when the battery cover is closed, the clamping block and the first extrusion inclined surface are extrusion-slidably engaged to cause the clamping block to slightly deform outward until it slides to face the card slot, and then it returns to its original state and is inserted into the card slot for clamping. When removing the battery cover, the second extrusion inclined surface and the mating inclined surface are extrusion-slidably engaged to drive the clamping block to slightly deform and disengage from the card slot until it slides away from the boss and then returns to its original state.

[0018] Preferably, a plurality of groups of clamping blocks and card slots are circumferentially spaced around the boss.

[0019] With the above solution, setting a plurality of groups ensures the clamping strength between the battery cover and the housing.

[0020] Preferably, a guiding structure for preventing the battery cover from rotating during the closing process is provided between the boss and the groove. The guiding structure includes a guiding block protruding from the inner side wall of the groove and a guiding groove provided on the boss for the guiding block to insert and guide linear movement.

[0021] With the above solution, before the battery cover is closed, the guiding block and the guiding groove are aligned. At this time, the clamping block and the card slot are aligned. During the closing process, the guiding block is inserted into the guiding groove and is guided and slidably engaged with the guiding groove, avoiding the misalignment of the clamping block and the card slot caused by the rotation of the battery cover, and ensuring that the clamping block is smoothly inserted into the card slot for clamping.

[0022] Since the present utility model adopts the above technical solutions, it has remarkable technical effects: Since the contact surface between the battery cover and the housing is fitted, and the battery cover itself is thin and has a smooth surface, it is difficult to apply force. Therefore, the buckle groove is used as a force application point to apply an external force to release the clamping between the battery cover and the housing so that the two are separated. When the buckle groove on one side of the outer wall of the battery cover is completely blocked by the shielding member, there is no force application point on the battery cover, making it difficult to open the battery cover. When disassembling the battery cover, it is necessary to first drive the shielding member to elastically retract until the buckle groove is exposed as a force application point, and then apply force to the buckle groove to drive the battery cover to move away from the housing to release the clamping with the housing. The disassembly of the battery cover can be achieved by two independent and combined actions of exposing the force application point and driving the battery cover to move upward, ensuring safety and meeting the standards in the CE certification.
