Technical Field

[0001] This utility model relates to the field of cover plate technology, specifically to a stamped lightweight cover plate structure. Background Technology

[0002] Stamping is a metal sheet processing technology that uses pressure to shape sheet metal into the desired shape. It is widely used in fields such as automobile manufacturing. The process is usually divided into two stages: preparation and stamping, in order to efficiently produce high-precision parts. Lightweighting is a technical concept that improves performance by reducing the weight of a product. Its core goal is to optimize weight while ensuring strength and function.

[0003] Lightweight cover plates have a wide range of applications. In the battery field, motor cover plates are made of magnesium alloy (30% lighter than aluminum alloy), and the surface micro-arc oxidation technology solves the corrosion problem. At high temperatures, the battery range degradation is reduced by 10%, which can improve the battery stability. In the existing technology, when the cover plate is hit, cracks are generated at the cover plate joint due to material shrinkage or vibration, which damages the waterproof seal. This can lead to a short circuit between the battery and the cover plate, which in turn affects the battery's service life. Utility Model Content

[0023] 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.

[0024] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A lightweight stamped cover structure includes a cover plate 1, a buffer plate 2 at the bottom of the cover plate 1, and two support blocks 10 fixedly connected to the bottom of the cover plate 1. A locking assembly is provided outside the support blocks 10, comprising two positioning blocks 11 respectively disposed outside the two support blocks 10. A return spring 12 is fixedly connected to the outside of each positioning block 11. An L-shaped rod 13 is fixedly connected to the end of the return spring 12 away from the positioning block 11. A limit rod 14 is fixedly connected to the side of the support block 10 closest to the positioning block 11. The limit rod 14 and the L-shaped rod... 13. The top of the buffer plate 2 has two rectangular grooves 9, and the inside of the rectangular grooves 9 is fixedly connected to a locking block 15. The top of the cover plate 1 has two threaded holes 7, and the inner circular wall of the threaded holes 7 is threaded with screws 6. The screws 6 are fixedly connected to the pressing block 8. The top of both the cover plate 1 and the buffer plate 2 has two limiting holes 4. The top of the cover plate 1 is fixedly connected to two insulating rings 3. The bottom of the cover plate 1 is fixedly connected to two rubber rings 5. The bottom of the rubber rings 5 ​​is fixedly connected to the buffer plate 2. The end of the limiting rod 14 away from the support block 10 is fixedly connected to a limiting cap 18.

[0025] By using the screw 6, when the cover plate 1 needs to be removed, the screw 6 is rotated clockwise, and the screw 6 moves along the inner wall of the threaded hole 7 towards the buffer plate 2. Then, the pressing block 8 moves towards the buffer plate 2, and the L-shaped rod 13 rotates counterclockwise around the pressing block 8. Then, the return spring 12 moves towards the positioning block 11. When the bottom of the L-shaped rod 13 leaves the locking block 15, the cover plate 1 can be removed. Then, the elastic potential energy generated by the compression of the return spring 12 causes the L-shaped rod 13 to move away from the positioning block 11, and the L-shaped rod 13 returns to its original position. After removal, the screw 6 is rotated counterclockwise, and the screw 6 moves along the inner wall of the threaded hole 7 away from the buffer plate 2. When the pressing block 8 is in contact with the top of the L-shaped rod 13, the rotation of the pressing block 8 stops. Through the above operation, the cover can be quickly fixed and removed, so as to improve the stability of the cover plate 1 and the buffer plate 2 and reduce the working time of the staff.

[0026] When further fixing of the cover plate 1 is required, the support block 10 is moved towards the buffer plate 2 via the support block 10, causing the support block 10 to move inside the rectangular groove 9. This causes the positioning block 11, the return spring 12, the pressing block 8, and the L-shaped rod 13 to move towards the buffer plate 2. Subsequently, the L-shaped rod 13 moves towards the locking block 15 and then rotates counterclockwise around the pressing block 8. This causes the return spring 12 to move towards the positioning block 11. When the bottom of the L-shaped rod 13 passes the locking block 15, the elastic potential energy generated by the compression of the return spring 12 causes the L-shaped rod 13 to move away from the positioning block 11, thus locking the return spring 12. The cover plate 1 and the buffer plate 2 are then fixed, which improves the supporting force of the cover plate 1 and the buffer plate 2 and prevents the battery from colliding with the cover plate 1 and short-circuiting when the battery is bumped, thereby affecting the battery's service life.

[0027] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The bottom of the cover plate 1 is fixedly connected to two cross blocks 16, and the top of the buffer plate 2 is provided with two cross grooves 17, with the cross blocks 16 and the cross grooves 17 being movably connected.

[0028] With the cover plate 1 in place, when it needs to be installed, first align the cover plate 1 with the top of the battery casing, then align the two limiting holes 4 with the positive and negative terminals of the battery, and move the limiting holes 4 towards the buffer plate 2. Then, the cross block 16 moves along the inside of the cross groove 17 towards the rubber ring 5, thus completing the initial positioning and engagement of the cover plate 1 and the buffer plate 2. When the battery needs to be repaired, move the cover plate 1 away from the buffer plate 2, so that the limiting holes 4 move away from the buffer plate 2. Then, the cross block 16 moves along the inside of the cross groove 17 away from the rubber ring 5. Through the above operations, the fixing, installation and removal of the cover plate 1 can be completed quickly, improving the work efficiency of the staff.

[0029] Working principle: Please refer to Figures 1-6 As shown, by using the screw 6, when the cover plate 1 needs to be removed, the screw 6 is rotated clockwise, and the screw 6 moves along the inner wall of the threaded hole 7 towards the buffer plate 2. Then the pressing block 8 moves towards the buffer plate 2, and the L-shaped rod 13 starts to rotate counterclockwise around the pressing block 8. Then the return spring 12 moves towards the positioning block 11. When the bottom of the L-shaped rod 13 leaves the locking block 15, the cover plate 1 can be removed. Then the elastic potential energy generated by the compression of the return spring 12 causes the L-shaped rod 13 to move away from the positioning block 11, and the L-shaped rod 13 returns to its original position. After removal, the screw 6 is rotated counterclockwise, and the screw 6 moves along the inner wall of the threaded hole 7 away from the buffer plate 2. When the pressing block 8 is in contact with the top of the L-shaped rod 13, the rotation of the pressing block 8 stops. Through the above operation, the cover can be quickly fixed and removed, so as to improve the stability of the cover plate 1 and the buffer plate 2 and reduce the working time of the staff.

[0030] When further fixing of the cover plate 1 is required, the support block 10 is moved towards the buffer plate 2 via the support block 10, causing the support block 10 to move inside the rectangular groove 9. This causes the positioning block 11, the return spring 12, the pressing block 8, and the L-shaped rod 13 to move towards the buffer plate 2. Subsequently, the L-shaped rod 13 moves towards the locking block 15 and then rotates counterclockwise around the pressing block 8. This causes the return spring 12 to move towards the positioning block 11. When the bottom of the L-shaped rod 13 passes the locking block 15, the elastic potential energy generated by the compression of the return spring 12 causes the L-shaped rod 13 to move away from the positioning block 11, thus locking the return spring 12. The cover plate 1 and the buffer plate 2 are then fixed, which improves the supporting force of the cover plate 1 and the buffer plate 2 and prevents the battery from colliding with the cover plate 1 and short-circuiting when the battery is bumped, thereby affecting the battery's service life.

[0031] With the cover plate 1 in place, when it needs to be installed, first align the cover plate 1 with the top of the battery casing, then align the two limiting holes 4 with the positive and negative terminals of the battery, and move the limiting holes 4 towards the buffer plate 2. Then, the cross block 16 moves along the inside of the cross groove 17 towards the rubber ring 5, thus completing the initial positioning and engagement of the cover plate 1 and the buffer plate 2. When the battery needs to be repaired, move the cover plate 1 away from the buffer plate 2, so that the limiting holes 4 move away from the buffer plate 2. Then, the cross block 16 moves along the inside of the cross groove 17 away from the rubber ring 5. Through the above operations, the fixing, installation and removal of the cover plate 1 can be completed quickly, improving the work efficiency of the staff.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
