[0031] Embodiment 1:
[0032] Figures 1-9The utility model provides a kind of mobile phone model machine structure of rear cover replacement provided by the utility model, including front cover 1 and rear cover 2, front cover 1 and rear cover 2 are connected each other by buckle cooperation mode, the back of front cover 1 is equipped with installation groove 4, the side of the bottom of installation groove 4 is equipped with buckle groove 41, installation groove 4 is vertically configured, buckle groove 41 is horizontally configured, installation groove 4 is communicated with buckle groove 41, the section of both is '' L '' type, the front of rear cover 2 is equipped with clasp 3, clasp 3 is connected in the inside of the edge of rear cover 2, clasp 3 includes movable part 31 and bending part 32 connected with each other, wherein movable part 31 is directly connected with rear cover 2, the edge of rear cover 2 has bending tenacity, pressing the edge of rear cover 2 will make it slightly bend, clasp 3 will also be slightly offset, when in this pressing state, entire clasp 3 can pass through installation groove 4 until the bottom of installation groove 4, then loosen the edge of rear cover 2, rear cover 2 then restores to relaxed state, at this time, bending part 32 is clamped into buckle groove 41, rear cover 2 is fixed on the back of front cover 1.
[0033] Clasp 3, installation groove 4 constitute a group of installation components, two groups of installation components are configured in the embodiment, and symmetrically arranged on the left and right sides of model machine, just can be adapted to single-handedly grip rear cover 2 when two side edges of rear cover 2 are forced simultaneously.
[0034] Magnet 42 is additionally provided on the groove wall of buckle groove 41, and iron sheet 33 is correspondingly provided at the end of bending part 32. After bending part 32 is embedded in buckle groove 41, magnet 42 attracts iron sheet 33, thereby strengthening the connection between bending part 32 and buckle groove 41, and ensuring that bending part 32 will not come out of buckle groove 41.
[0035] In order to facilitate the cooperation of clasp 3 and installation groove 4, and the cooperation of entire front cover 1 and rear cover 2, positioning devices are respectively arranged on front cover 1 and rear cover 2. Specifically, positioning groove 11 is arranged on the back of front cover 1, and positioning column 21 cooperating with positioning groove 11 is arranged on the front of rear cover 2. During installation, positioning column 21 is first aligned with positioning groove 11 and inserted, and after slightly shaking rear cover 2 to feel that positioning column 21 has been inserted to achieve positioning effect, clasp 3 is continuously installed.
[0036] Positioning groove 11 has four and is separately arranged at the corners of front cover 1, and positioning column 21 also has four and is separately arranged at the corners of rear cover 2, to ensure that the force is uniform during positioning and installation.
[0037] The model machine usually needs to embed a counterweight in the interior, in the embodiment, a counterweight cavity is formed between the front cover 1 and the rear cover 2, the counterweight is arranged in the counterweight cavity, and at least four limiting blocks 22 are arranged on the side of the rear cover 2 facing the front cover 1. The main function of the limiting blocks 22 is to ensure that the counterweight can be accurately placed at a predetermined position in the counterweight cavity and effectively prevent displacement of the counterweight due to external vibration or shaking during operation of the equipment. The limiting blocks 22 provide fixed support by being in contact with the counterweight, so that the counterweight can remain stable even if the equipment is subjected to external impact, thereby ensuring stable center of gravity of the model machine.
[0038] The limiting blocks 22 are in the shape of a circular truncated cone with the upper part being narrow and the lower part being wide. The design of the circular truncated cone can better adapt to the shape of the counterweight and provide more uniform pressure distribution, thereby providing a guiding effect when the counterweight is installed.
[0039] Installation process:
[0040] Pick up the rear cover 2, align the four positioning columns 21 on the front of the rear cover 2 with the four positioning grooves 11 on the back of the front cover 1, and gently move the rear cover 2 close to the front cover 1 so that the positioning columns 21 are smoothly inserted into the positioning grooves 11. Slightly shake the rear cover 2 to confirm that the positioning columns 21 have been completely inserted into the positioning grooves 11. Hold the two side edges of the rear cover 2 with both hands and press inward with uniform force. At this time, the side edges of the rear cover 2 will slightly bend due to the bending flexibility, causing the movable part 31 of the hook 3 to shift, and the bending part 32 can smoothly pass through the installation groove 4 on the front cover 1. Then press the rear cover 2 tightly against the front cover 1, and the hook 3 reaches the bottom of the installation groove 4. After releasing the pressure on the side edges of the rear cover 2, the side edges of the rear cover 2 return to their original state, and the hook 3 also returns to its original position, and the bending part 32 is embedded in the buckling groove 41 at the bottom of the installation groove 4. At this time, the magnet 42 in the buckling groove 41 will attract the iron sheet 33 at the end of the bending part 32 of the hook 3, further reinforcing the connection between the bending part 32 and the buckling groove 41, and ensuring that the hook 3 will not come out of the buckling groove 41. Finally, check whether the rear cover 2 has been completely fixed by gently shaking it, and the installation of the rear cover 2 is completed after confirming that it is correct. If it is necessary to disassemble the rear cover 2, simply repeat the action of pressing the side edges of the rear cover 2 to make the hook 3 come out of the buckling groove 41, and then gently pull out the rear cover 2. This design makes the replacement of the rear cover 2 simple and fast, and facilitates the replacement of different styles of rear covers 2 according to different display requirements.
[0041] The above description is only an optional embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection range of the present application.
