[0002] With the popularization and upgrading of electronic devices, the function and performance of cover plates have become increasingly important. Cover plates are not only for the protection of appearance, but also bear multiple functions such as impact resistance and electromagnetic interference. Although traditional plastic materials are lightweight and low cost, they are insufficient in terms of strength and protection.

[0003] The covers of electronic devices inside modern electronic devices are usually fixed with screws or bolts, which makes assembly troublesome, maintenance and repair inconvenient, and the complex structure makes it easy to lose the fixing bolts. To address this, we propose a cover for electronic devices. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 A cover plate for an electronic device includes a bottom frame 1 and a top cover plate 2 that are fitted together, a fixing member 3 located in the middle, and a spring member 4. The bottom frame 1 has a hollow fitting frame 7 at the center of one end face corresponding to the top cover plate 2, and the top cover plate 2 has a hollow fitting frame 10 that fits and engages with the fitting frame 7 at one end face corresponding to the bottom frame 1. The bottom frame 1 has two spring members 4 that are symmetrically distributed along an axis, and the bottom frame 1 has two fixing members 3 that are symmetrically distributed along an axis that engage with the spring members 4 on the side.

[0022] Furthermore, the bottom frame 1 has a rectangular axisymmetric structure, and the two symmetrical ends of the bottom frame 1 corresponding to the connecting spring 4 are provided with fixing chambers 5. The side of the bottom frame 1 facing away from the top cover plate 2 and perpendicular to the two fixing chambers 5 is provided with an extension plate 8. The two ends of the extension plate 8 are provided with connecting holes 9 distributed in an axisymmetric manner. The end face of the bottom frame 1 facing away from the top cover plate 2 is provided with a sealing groove 6. The fixing chambers 5 can limit and fix the spring 4, and also fix the fixing part 3. The axisymmetrically distributed connecting holes 9 can be effectively connected to the circuit board of the electronic device.

[0023] Furthermore, the top cover 2 is composed of a second mating frame 10 and a rectangular plate 11 fixedly connected together. The rectangular plate 11 is located at the top of the second mating frame 10, and the rectangular plate 11 has connecting blocks 12 on two opposite sides of one end face of the second mating frame 10. The connecting blocks 12 have rotating holes 13 inside. The second mating frame 10 and the first mating frame 7 can effectively isolate electronic devices that require special protection, ensuring the safety of the electronic devices that require special protection.

[0024] Furthermore, the fixing member 3 is connected to two axisymmetrically distributed limiting blocks 14 on one end face of the top cover plate 2, which are parallel to the rectangular plate 11. A rotating connecting rod 15 that is connected to the rotating hole 13 is provided between the two limiting blocks 14. The fixing member 3 is connected to one end face of the bottom frame 1, which is connected to the spring member 4. A set of spring group 17 is welded to one end of the fixing member 3 near the end face of the locking block 16, which is parallel to the second mating frame 10. The end of the spring group 17 away from the locking block 16 is provided with a mating plate 18 that is welded to the second mating frame 10. When the spring group 17 is protecting the electronic device, it is in a compression device, which effectively ensures that the locking block 16 can be connected inside the fixing compartment 5.

[0025] Furthermore, the spring component 4 is composed of three parts: mating plate 219, spring assembly 20, and mating plate 31. The middle structure of the spring component 4 is spring assembly 20. The mating plate 219 and mating plate 31 are both snapped into the inside of the fixing chamber 5, and the mating plate 219 can contact and engage with the snapping block 16 of the fixing component 3.

[0026] Furthermore, mating plate 29 and mating plate 3 21 are welded to both ends of spring assembly 20 respectively. Spring assembly 20 is composed of two rows of four springs at equal intervals. Spring assembly 20 is always in a compressed state, effectively ensuring the fixation of snap-fit ​​block 16.

[0027] Working principle: The cover plate of the electronic device is correctly installed according to the diagram. Around the electronic device requiring special protection inside the device, there are openings that are fixed to the bottom frame 1 using matching screws. A sealing groove 6 is provided between the end face of the bottom frame 1 and the bottom circuit board to hold a rubber sealing ring. Therefore, the electronic device requiring special protection is placed in the mating frame 7 inside the bottom frame 1. Springs 4 are located inside the two symmetrically distributed fixing chambers 5 of the bottom frame 1. The operator compresses the fixing pieces 3 on the two opposite end faces of the top cover plate 2 by hand and aligns the mating frame 10 of the top cover plate 2 with the mating frame 7 of the bottom frame 1 for insertion. At this time, the two ends of the fixing part 3 effectively compress the spring part 4 inside the fixing chamber 5. After the snap-fit ​​block 16 of the fixing part 3 is fully inserted into the interior of the fixing chamber 5, the staff releases the fixing part 3. Both the fixing part 3 and the spring part 4 rebound, and the mating frame 7 of the fixing part 3 is snapped into the interior of the fixing chamber 5. Thus, the electronic device that needs special protection is effectively protected, effectively preventing collisions and providing dust protection. When the internal electronic device needs to be repaired or maintained, the staff only needs to compress the fixing parts 3 at both ends of the top cover 2 and compress the top cover 2 downward as a whole, and then pull it out. This effectively improves the efficiency of repair and maintenance and reduces time costs.
