[0002] A battery cover is a component in electronic devices used to cover the battery compartment, protect the battery, and ensure stable operation of the device. It is typically located at the rear or bottom of the device, serving a sealing, protective, and securing function. The screw-proof structure on the battery cover's plastic component is primarily used to ensure the battery cover remains securely connected to the device during use, preventing it from loosening or falling off due to vibration, external force, or prolonged use. Existing technologies often use retaining rings to limit the screw's movement from the battery cover, but this adds extra production costs and complicates the manufacturing process. Furthermore, it prevents the screw from springing back when it is in the open position, reducing the operator's efficiency in assembling and disassembling the battery cover. Therefore, we propose a structure that automatically springs the screw back from the battery cover's plastic component, preventing it from falling off. Utility Model Content

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-3As shown, the present invention proposes a structure for a screw to automatically pop up from the battery cover and prevent it from falling off, including a battery box 1, a battery cover 2, and a screw 3. The screw 3 includes a nut 31, a smooth post 32 is provided below the nut 31, one end of the smooth post 32 is installed corresponding to one side of the nut 31, and one end of the smooth post 32 is fixedly connected to one side of the nut 31. A threaded post 33 is provided at one end of the smooth post 32 away from the nut 31, the other end of the smooth post 32 is installed corresponding to one end of the threaded post 33, and the other end of the smooth post 32 is fixedly connected to one end of the threaded post 33. The nut 31, the smooth post 32, and the threaded post 33 are integrally formed.

[0020] The battery cover 2 has an assembly groove 4, and the bottom inner wall of the assembly groove 4 has a post hole 5. The outer ring of the smooth post 32 fits into the inner wall of the post hole 5. The smooth post 32 is installed correspondingly to the post hole 5. The outer ring of the threaded post 33 abuts against one side of the battery cover 2. The threaded post 33 abuts against one side of the battery cover 2 through its external thread, thereby preventing the screw 3 from detaching from the battery cover 2. At the same time, it avoids the traditional snap ring structure, reducing production costs and processes. A return spring 6 is provided in the assembly groove 4. One end of the return spring 6 is installed correspondingly to the inner wall of the assembly groove 4 and is fixedly connected to the inner wall of the assembly groove 4. The other end of the return spring 6 abuts against the lower side of the nut 31. When the return spring 6 is in the initial state, it can... Nut 31 is lifted up, so that the external thread of threaded post 33 abuts against one side of battery cover 2, making it easy for the operator to disassemble and assemble the battery cover. Return spring 6 is sleeved on the outside of smooth post 32. Smooth post 32 is slidably connected to post hole 5. Nut groove 7 is opened in battery box 1. One side of nut groove 7 is opened on battery box 1. Nut 8 is set in nut groove 7. The outer periphery of nut 8 is installed corresponding to the inner wall of nut groove 7. The mounting end of nut 8 is fixedly connected to the inner wall of nut groove 7. When screw 3 is in the locked state, threaded post 33 is installed corresponding to nut 8. When screw 3 is in the locked state, threaded post 33 is threadedly connected to nut 8. The setting of nut 8 can cooperate with screw 3 to fasten battery box 1 and battery cover 2.

[0021] When screw 3 is in the open state, the threaded post 33 is disengaged from nut 8 and located between the opening groove 9 and battery cover 2. When screw 3 is in the open state, the opening groove 9 can ensure that screw 3 avoids the situation where the battery cover 2 cannot be opened due to space constraints when the battery cover 2 is moved horizontally.

[0022] In this embodiment, when the operator needs to assemble the battery cover 2 and the battery box 1, the operator aligns the positions of the battery cover 2 and the battery box 1, and then presses the nut 31 down so that the nut 31 drives one end of the threaded post 33 to align with the inner ring of the nut 8 through the smooth post 32. Then the operator rotates the nut 31 so that the threaded post 33 and the nut 8 are threadedly connected. When the threaded post 33 and the nut 8 are fully assembled, the battery cover 2 and the battery box 1 are in a tight assembly state, and at the same time, the return spring 6 is in a compressed state.

[0023] When the operator needs to remove the battery cover 2 from the battery box 1, the operator first rotates the nut 31. The rotation of the nut 31 drives the threaded post 33 to rotate through the smooth post 32, causing the threaded post 33 to disengage from the nut 8. When the threaded post 33 disengages from the nut 8, the screw 3 springs up under the reset action of the return spring 6, and the smooth post 32 slides in the post hole 5. At this time, the threaded post 33 is located in the opening groove 9. Finally, the operator pulls the battery cover 2 to one side to disengage the battery cover 2 from the battery box 1.

[0024] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
