Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a self-locking screw device for battery assembly. Background Technology

[0002] Battery assembly is a complex process involving multiple steps and the precise combination of components to ensure the performance, safety, and reliability of the final product. It requires the use of bolts and screws to assemble different parts together.

[0003] In current battery assembly technology, individual cells are typically grouped according to design requirements and connected in series or parallel to form battery modules through welding or mechanical connections. The modules are then installed into the battery casing, along with the battery management system and related wiring harnesses. Next, the battery cover is positioned and fixed to the top of the casing. Nuts are aligned with the mounting holes on the battery cover manually or using automated equipment. Bolts are then passed through the battery cover and BMS components and screwed into the nuts to complete the tightening. However, current battery assembly technology requires manual visual positioning of the screw holes to align the bolts and nuts with the mounting holes, which is time-consuming. Furthermore, when manually lifting the nuts and bolts for threaded connection, the nuts are easily squeezed and displaced by the bolts, potentially causing them to fall into the battery assembly and cause damage.

[0004] Therefore, there is a need for a self-locking screw device for battery assembly that can automatically lift and align the nut with the bolt. Utility Model Content

[0005] To overcome the shortcomings of existing battery assembly technology, which requires manual visual positioning of screw holes to align bolts and nuts with mounting holes, is time-consuming, and when manually lifting the nut and bolt for threaded connection, the nut is easily squeezed and displaced by the bolt, causing it to fall into the battery assembly and cause damage, this utility model provides a self-adaptive screw-locking device for battery assembly that can automatically lift the nut and align it with the bolt.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: A self-locking screw device for battery assembly, comprising a base, a support plate, a product placement seat, a battery pack, a battery management system (BMS), a battery cover, and a support frame. Two support plates are fixedly connected to the base. The product placement seat is fixedly connected to the base, and a battery pack is placed on the product placement seat. The battery pack is equipped with a BMS. The support frame is fixedly connected to the base, and the battery cover is placed on the support frame. The device also includes a first mounting base, a slide rail, a slider, a second mounting base, a fixing block, a guide frame, a third mounting base, a feeding plate, a fixing base, a fixing rod, a push rod, and a connecting rod. The two support plates... A first mounting base is fixedly connected to the first mounting base. Two slide rails are mounted on the first mounting base, and sliders are slidably mounted on the slide rails. A second mounting base is installed between the two sliders. Two fixing blocks are fixedly connected to the second mounting base. Two guide frames are fixedly connected to the first mounting base. The fixing blocks slide on adjacent guide frames. A third mounting base is fixedly connected to the second mounting base. A feeding plate is fixedly connected to the third mounting base. The feeding plate has multiple placement slots. A fixing seat is fixedly connected to the first mounting base. A fixing rod is rotatably mounted on the fixing seat. A push rod is fixedly connected to the fixing rod. A connecting rod is rotatably mounted on the fixing rod. The connecting rod is rotatably connected to the second mounting base.

[0007] In a preferred embodiment of the present invention, the device further includes a clamp, a fixed cover plate, and a connecting block. The clamp is provided on the support frame, and the clamp has multiple first through holes. The connecting block is fixedly connected to the clamp, and the fixed cover plate is rotatably provided on the connecting block. The fixed cover plate has multiple second through holes.

[0008] In a preferred embodiment of the present invention, a fixing plate, a limiting protrusion, and a rotating shaft are further included. The rotating shaft is rotatably mounted on the fixing plate, and the base is fixedly connected to the rotating shaft. The limiting protrusion is fixedly connected to the fixing plate, and a limiting groove is opened on the base, allowing the limiting protrusion to slide within the limiting groove.

[0009] In a preferred embodiment of the present invention, a rubber sleeve is also included, and the push rod is fitted with a rubber sleeve.

[0010] In a preferred embodiment of the present invention, a support rod is further included, and the support rod is fixedly connected to the first mounting base.

[0011] In a preferred embodiment of this utility model, the limiting groove is arc-shaped.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By rotating the push rod, the fixed rod and the connecting rod are driven to rotate. While the connecting rod rotates, it squeezes the second mounting seat to move to the right. While the second mounting seat moves to the right, it drives the third mounting seat, the feeding plate, the two sliders and the two fixed blocks to move to the right. The movement of the feeding plate drives the nut in the placement slot to move into the battery cover. This allows the nut to automatically align with the mounting hole on the battery cover, thus eliminating the need for manual positioning of the bolt hole and preventing the nut from falling into the battery pack and causing damage during manual installation.

[0013] 2. By rotating the fixed cover plate and pushing the battery cover into the clamp, the fixed cover plate is rotated back to its original position so that the fixed cover plate covers the battery cover and the first through hole and the second through hole correspond to the screw holes on the battery cover. Then the bolts are inserted into the first through hole and the second through hole. This can improve the bolt locking efficiency without additional visual positioning or mechanical adjustment.

[0014] 3. By rotating the base, the base drives the rotating shaft and all its components to rotate. The limiting protrusion and limiting groove limit the rotation angle of the base, which makes it easier to tighten the screws and bolts on the side of the battery cover, thereby speeding up the tightening efficiency.

The device also includes a first mounting base 13, a slide rail 14, a slider 15, a second mounting base 16, a fixing block 17, a guide frame 18, a third mounting base 19, a feeding plate 20, a fixing base 22, a fixing rod 23, a push rod 24, and a connecting rod 25. The first mounting base 13 is fixedly connected between the two support plates 2. The top of the first mounting base 13... A slide rail 14 is symmetrically installed front and back. A slider 15 is slidably installed on the slide rail 14. A second mounting base 16 is installed between two sliders 15. Fixing blocks 17 are fixedly connected to the front and back sides of the top of the second mounting base 16. A guide frame 18 is symmetrically fixedly connected to the top right side of the first mounting base 13. The fixing blocks 17 slide on the adjacent guide frame 18. A third mounting base 19 is fixedly connected to the second mounting base 16. A feeding plate 20 is fixedly connected to the third mounting base 19. Two placement slots 21 are symmetrically opened on the right side of the feeding plate 20. A fixing base 22 is fixedly connected to the top left side of the first mounting base 13. A fixing rod 23 is rotatably installed on the fixing base 22. A push rod 24 is fixedly connected to the fixing rod 23. A connecting rod 25 is rotatably installed on the upper part of the fixing rod 23. The lower end of the connecting rod 25 is rotatably connected to the second mounting base 16.

[0023] See Figure 1 , Figure 3 and Figure 4 As shown, it also includes a rubber sleeve 31, which is fitted onto the push rod 24. The rubber sleeve 31 increases the grip comfort of the push rod 24.

[0024] See Figure 3 and Figure 4 As shown, it also includes a support rod 2001. The support rod 2001 is fixedly connected to the first mounting base 13. The support rod 2001 supports the feeding plate 20 and prevents the feeding plate 20 from tilting.

[0025] When using this device, first place the battery pack 4 on the product placement seat 3, then place the battery cover 501 on the support frame 6. Next, place the nuts into the four placement slots 21 on the feeding plate 20, and then rotate the push rod 24. The push rod 24 drives the fixed rod 23 to rotate, and the fixed rod 23 drives the connecting rod 25 to rotate. While the connecting rod 25 rotates, it presses the second mounting seat 16 to move to the right. While the second mounting seat 16 moves to the right, it drives the third mounting seat 19, the feeding plate 20, the two sliders 15, and the two fixed blocks 17 to move to the right. The sliders 15 slide on the slide rail 14, the fixed blocks 17 slide on the guide frame 18, and the feeding plate 20 moves... The nut in the placement slot 21 is moved into the battery cover 501, so that the nut is automatically aligned with the mounting hole on the battery cover 501. This eliminates the need for manual positioning of the bolt holes and avoids the nut falling into the battery pack 4 and causing damage during manual installation. Then, the bolt is placed into the bolt hole on the battery cover 501 and passes through the mounting hole on the electronic component to be installed inside the battery cover 501. Finally, the bolt is turned so that it is screwed into the nut. After installation, the battery cover 501 is placed on the battery pack 4 to protect the BMS5. Then, the screws on the battery cover 501 are tightened to fix it to the battery pack 4.

[0026] Example 2: Based on Example 1, refer to Figure 1 and Figure 2 As shown, it also includes a clamp 8, a fixed cover plate 10, and a connecting block 12.

The fixed cover plate 10 is rotatably provided on the connecting block 12. Two second through holes 11 are opened on the front and back sides of the top of the fixed cover plate 10. The first through holes 9 and the second through holes 11 correspond to the mounting holes on the battery cover 501.

[0027] Before placing the battery cover 501 on the support frame 6, rotate the fixing cover plate 10 and push the battery cover 501 into the clamp 8. Then rotate the fixing cover plate 10 back to its original position so that the fixing cover plate 10 covers the battery cover 501 and the first through hole 9 and the second through hole 11 correspond to the screw holes on the battery cover 501. Then insert the bolts into the first through hole 9 and the second through hole 11. This can improve the bolt locking efficiency without additional visual positioning or mechanical adjustment.

[0028] See Figure 5 As shown, it also includes a fixed plate 28, a limiting protrusion 29 and a rotating shaft 30. The rotating shaft 30 is rotatably arranged in the middle of the fixed plate 28.
