Description

Technical Field

[0001] This utility model belongs to the field of battery assembly repair technology, specifically relating to a battery assembly flipping stand. Background Technology

[0002] When a battery pack is damaged, repair personnel are required to perform repairs. Current repair methods typically involve placing the battery on a vehicle lift. This method has the following drawbacks: 1. The battery cannot be secured on the lift, increasing the risk of accidents for repair personnel; 2. Because exterior repairs involve welding, grinding, and painting, the lift is fixed and cannot be moved, forcing these operations to be performed on the lift, which poses significant health risks and environmental hazards; 3. Repair personnel must maintain a tilted posture, increasing the risk of occupational diseases. Therefore, a battery pack tilting platform is proposed to address these shortcomings. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a battery assembly flipping platform to solve the problem that the maintenance of the battery assembly is inconvenient when it is placed on a lift in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A battery assembly flipping platform includes a platform body, a support mechanism, and a worm gear rotating assembly. The platform body is used to fix the battery assembly, and the worm gear rotating assembly is used to drive the platform body to rotate on the support mechanism.

[0006] The main body of the platform includes symmetrically arranged sliding plates, each equipped with an adjusting threaded rod slidably connected to the sliding plate. Adjusting nuts are provided on the adjusting threaded rods on both sides of the end of each sliding plate, and a fixing block is provided in the middle of each adjusting threaded rod.

A fixing bolt is provided at the other end of each slider to fix the battery assembly's fixing part to the slider. Fixing plates are symmetrically arranged on the outer surface of each sliding plate, with locking screws between the fixing plates. A connecting block is provided at the other end of each slider, with one end fixed to the slider and the other end slidably connected to the locking screw. Locking nuts are provided on the locking screws on both sides of the connecting block.

[0007] Furthermore, the support mechanism includes symmetrically arranged base plates, on which columns are provided. One end of each of the two columns is fixedly connected to the base plate. The other end of one column is provided with a rotating shaft, which is fixedly connected to a fixed block. The worm gear rotating assembly is fixed to the other end of the other column, and the output shaft of the worm gear rotating assembly is fixed to the other fixed block.

[0008] Furthermore, the worm gear rotating assembly also includes a housing, a worm gear, a worm, a drive shaft, and a turntable.

[0021] like Figures 1-3 As shown, a battery assembly flipping platform includes a platform body, a support mechanism, and a worm gear rotating assembly. The platform body is used to fix the battery assembly 20, and the worm gear rotating assembly is used to drive the platform body to rotate on the support mechanism.

[0022] The main body of the platform includes symmetrically arranged slide plates 9. The length of each slide plate 9 should be greater than the length of a typical battery assembly 20. Each symmetrically arranged slide plate 9 is equipped with an adjusting threaded rod, which is slidably connected to the slide plate 9. Adjusting nuts 8 are provided on the adjusting threaded rods on both sides of the end of each slide plate 9. A fixing block 6 is provided in the middle of each adjusting threaded rod. Each slide plate 9 is equipped with several sliders 14, which are slidably connected to the slide plate 9 in the middle. A fixing bolt 15 is provided on the other end of each slider 14. The fixing bolt 15 is used to fix the fixing part 21 of the battery assembly 20 to the mounting plate 9. On the slider 14 (it is easy to understand that the position where the fixing part 21 and the end of the slider 14 contact each other can be set according to the actual situation, as long as the fixing bolt 15 can be locked, which will not be elaborated here), the outer side of the slide plate 9 is symmetrically provided with fixing plates 16, and locking screws 17 are provided between the fixing plates 16. The other end of the slider 14 is provided with a connecting block 19. One end of the connecting block 19 is fixed to the slider 14, and the other end of the connecting block 19 is slidably connected to the locking screw 17. Locking nuts 18 are provided on the locking screws 17 on both sides of the connecting block 19.

[0023] The working principle of the above technical solution is as follows:

[0024] First, adjust the position of the slide plate 9 on the adjusting screw 7 according to the width of the battery assembly 20. That is, adjust it by sliding until the distance between the two symmetrically arranged slide plates 9 matches the width of the battery assembly 20 (this means that the fixing part 21 in the width direction of the battery assembly 20 can be fixed on the slider 14). Then, use the lifting assembly to lift the battery assembly 20 above the guard plate. Then, adjust the position of the slider 14 on the slide plate 9 so that the end of the slider 14 corresponds to the position of the battery fixing part 21. Then, lock the position of the slider 14 with the locking nut 18. Then, lower the battery assembly 20 with the lifting assembly so that the fixing part 21 contacts the end of the slider 14. Finally, fix the battery assembly 20 on the stand with the fixing bolt 15.

[0025] This configuration allows for adjustment of the position of the slide plate 9 on the adjusting screw 7, making it suitable for battery assemblies 20 of different widths. Simultaneously, the position of each slider 14 can be adjusted independently. Since the adjustment is achieved by clamping the slider onto the screw with the locking nut 18, each slider 14 can be adjusted to any position on the slide plate 9 for fixation. This high adjustment precision results in high matching accuracy with the fixing part 21 of the battery assembly 20. Therefore, each slider 14 can precisely correspond to the fixing part 21 of the battery assembly 20, providing excellent fixation. In summary, this flip stand is suitable for fixing different models of battery assemblies 20, offering strong practicality and excellent fixation. Furthermore, the battery assembly 20 can rotate 360 ​​degrees on this flip stand, facilitating easy adjustment of its position and simplifying maintenance.

[0026] In one feasible embodiment, the support mechanism includes symmetrically arranged base plates 1, on which columns 3 are mounted. One end of each column 3 is fixedly connected to the base plate 1, and the other end of one column 3 is equipped with a rotating shaft 5, which is fixedly connected to a fixed block 6. A worm gear rotating assembly is fixed to the other end of the other column 3, and the output shaft 11 of the worm gear rotating assembly is fixed to another fixed block 6. The columns 3 suspend the main body of the platform, thereby facilitating its rotation. Of course, the height of the columns 3 should be greater than the width of a typical battery assembly 20, so that it will not interfere with the ground during rotation.

[0027] In one feasible embodiment, the worm gear rotating assembly further includes a housing 10, a worm gear (not shown), a worm (not shown), a drive shaft 13, and a turntable 12. The worm gear is rotatably connected within the housing 10 and is meshed with the worm. One end of the drive shaft 13 is fixed to the worm, and the other end extends to the outside of the housing 10. The turntable 12 is fixed to the end of the drive shaft 13 located outside the housing 10. One end of the output shaft 11 is fixed to the worm gear, and the other end of the output shaft 11 extends out of the housing 10 and is fixed to the connecting block 19. It is easy to understand that the working principle of the worm gear rotating assembly controlling the rotation of the frame body is existing technology and will not be elaborated upon here. In this technical solution, by manually rotating the turntable 12, the drive shaft 13 is driven to rotate, which in turn drives the worm to rotate, which in turn drives the worm gear to rotate, which in turn drives the output shaft 11 to rotate, which in turn drives the fixed block 6 to rotate, and ultimately drives the entire frame body to rotate on the support assembly. At the same time, it's easy to understand that the worm gear has a self-locking effect, preventing reverse rotation after angle adjustment, thus ensuring the safety and reliability of the mechanical transmission. Of course, components such as pins can also be installed to block the reverse rotation of turntable 12; the appropriate option can be selected based on the actual situation, which will not be elaborated upon here.

[0028] In one feasible method, a number of rollers 2 are provided on the bottom surface of the fixed plate 16. The rollers 2 are universal wheels with a self-locking structure. The universal wheels facilitate the movement of the flipping platform, making it easier to move the repaired battery assembly 20 to areas such as the paint booth for subsequent repairs, making it more convenient to use.

[0029] In one feasible embodiment, diagonal braces 4 are provided on both sides of the column 3, with the two ends of the diagonal braces 4 fixed to the base plate 1 and the column 3 respectively, which can enhance the load-bearing capacity of the column 3 and ensure the safety and stability of the tilting platform.

[0030] It should be noted that although there are existing technology for rotating test benches for battery assembly repair, such as a power battery pack rotating test bench with patent number CN204165739U, which includes a test bench body, a support mechanism and a rotating mechanism, the test bench body is fixed to the base surface by the support mechanism and the rotating mechanism is placed on the support mechanism. While existing flip-over platforms in patents can achieve a certain degree of fixation and flipping of battery assemblies, they suffer from the following problems during use: Different battery assemblies have different widths, and the width of the platform body in existing patents is adjusted via connecting holes and mounting holes. This adjustment is inconvenient and lacks precision (because there is a gap between adjacent mounting holes, the minimum adjustment precision is the gap between two mounting holes; even after adjustment, the width may not match the battery assembly width). Therefore, it is unsuitable for repairing different battery assemblies, leading to inconvenience during use. Furthermore, existing patents use waist holes of varying lengths to accommodate different mounting point (mounting part) positions of the power battery. This method is only suitable for battery assemblies with small differences in mounting points, not for battery assemblies with significant differences in mounting points. The flip-over platform design in this application perfectly solves the technical problems existing in existing patents, resulting in better performance.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
