[0002] With the rapid development of the automobile industry, electric vehicles are becoming more and more popular, and the demand for replacement and maintenance of automobile battery packs is also growing. In the field of automobile repair and maintenance, equipment for replacement and maintenance of automobile battery packs continues to emerge to improve maintenance efficiency and ensure maintenance quality. Existing automobile battery pack replacement and maintenance equipment usually has a basic replacement and maintenance platform that can meet the needs of disassembling the automobile battery and placing it on the platform for subsequent operations. However, this type of equipment has exposed some problems that need to be solved in actual use;

[0003] When performing replacement and maintenance operations on car batteries, the disassembled car batteries are placed on the replacement and maintenance table. Since various external forces will inevitably be applied to the battery during the operation, such as the touch of maintenance tools, misoperation by maintenance personnel, etc., the car battery is easily displaced. When the external force is large, the car battery may even fall off the replacement and maintenance table, causing battery damage. This not only increases the maintenance cost, but also may not be able to restore the vehicle to normal use in time due to battery damage, causing inconvenience to users. In addition, in the use scenarios of the equipment, it is often necessary to move the replacement and maintenance table. Whether moving the equipment to a suitable maintenance station or transferring it between different maintenance areas, the inertia during the movement and the impact force generated by accidental collisions that may be suffered during the movement will put the car battery placed on the replacement and maintenance table at risk of displacement and falling. Once the car battery falls, in addition to the possible physical damage to the battery itself, it may also cause damage to the internal structure of the battery, affecting the battery performance and safety, and may even cause safety accidents;

[0019] Battery replacement and maintenance operations: After completing the battery fixation, the auto repair personnel can replace or maintain the car battery. At this time, the tools placed in the tool storage box on the bottom plate can be used at any time, which is convenient for the auto repair personnel to perform related operations. During the operation, if the clamping protection device is not needed, rotate the internal thread locking sleeve A and the internal thread locking sleeve B to separate them from the anti-slip block A and the anti-slip block B, and the metal clamping strip A and the metal clamping strip B can be rotated to a downward vertical state through the sleeve hole, which will not hinder the operation of the auto repair personnel. After the operation is completed, reverse the clamping protection device to restore it to its initial state for the next use.

[0020] Compared with the prior art, the present invention provides a device and method for quickly replacing and maintaining a vehicle battery pack, which has the following beneficial effects:

[0021] The present invention adds a new type of clamping protection device on both sides of the center of the bottom end of the replacement and maintenance platform.

The automobile battery pack quick replacement and maintenance device according to claim 8, characterized in that: The hydraulic lifter (14) can drive the replacement maintenance platform (9) to move up and down through the hydraulic shaft and the metal fixed shaft sleeve (15), and the plurality of metal lifting sleeves (7) can move up and down synchronously outside the support bracket (1), and the plurality of metal lifting sleeves (7) are mutually connected with reinforcing connecting rods at the center.

8. The automobile battery pack quick replacement and maintenance device according to claim 1, characterized in that: A plurality of downwardly recessed long grooves (10) are equidistantly arranged inside the top of the replacement and maintenance platform (9), and anti-slip strips (11) are fixed in each of the plurality of long grooves (10), and the top outer wall of the anti-slip strip (11) protrudes above the top outer wall of the replacement and maintenance platform (9).

9. A method for rapid replacement and maintenance of an automotive battery pack according to any one of claims 1 to 8, characterized in that: Equipment movement and positioning: After the car is lifted by the lift, the operator holds the push-pull handrails (8) welded on the left and right ends of the replacement maintenance platform (9), and uses the flexible steering function of the universal wheels (6) at the bottom of the support bracket (1) to push the equipment to the bottom of the lifted car battery module. Since the outer corners of the push-pull handrails (8) are arc-surface passivated, they are ergonomic, making it more comfortable for the operator to push, and can effectively avoid accidental injuries. After reaching the appropriate position, the equipment is fixed by the brake function of the universal wheels (6); Height adjustment: If it is necessary to adjust the height of the replacement maintenance platform (9), operate the hydraulic lifter (14). When the hydraulic system inside the hydraulic lifter (14) pushes the hydraulic shaft to move upward, the replacement maintenance platform (9) is driven to rise through the metal fixed shaft sleeve (15); when the hydraulic shaft moves downward, the replacement maintenance platform (9) is lowered accordingly. In this process, multiple metal lifting sleeves (7) move up and down synchronously on the outside of the support bracket (1), and the reinforced connecting rods at the center of the multiple metal lifting sleeves (7) ensure the stability and integrity of the replacement maintenance platform (9) during the lifting process, so that it can accurately reach the required height, such as fitting to the bottom of the car battery or descending to a height that is convenient for operation; Battery fixing: After the replacement maintenance table (9) rises to the top and fits against the bottom of the car battery, the clamping protection device (12) is operated to fix the car battery. The anti-slip block A (17) and the anti-slip block B (23) are driven by rotating the manual operating rod (25), so that the adjustable long rod screw A (19) and the adjustable long rod screw B (21) rotate clockwise and counterclockwise in the internal thread fixing long cylinder (20) and move forward and backward. After adjusting to the appropriate position, the metal clamping strip A (18) and the metal clamping strip B (22) are respectively tightly fitted on the left and right sides of the car battery. The front and rear ends of both sides firmly fix the automobile battery on the replacement maintenance table (9). During this process, if the position of the metal clamping strip A (18) and the metal clamping strip B (22) needs to be adjusted, the internal thread locking sleeve A (16) and the internal thread locking sleeve B (24) can be rotated to move forward and backward outside the adjustable long rod screw A (19) and the adjustable long rod screw B (21), and cooperate with the anti-slip block A (17) and the anti-slip block B (23) to achieve the position adjustment and fixation of the metal clamping strip A (18) and the metal clamping strip B (22); Battery replacement and maintenance operation: After the battery is fixed, the auto repair personnel can replace or maintain the car battery. At this time, the tools placed in the tool storage box (4) on the bottom plate (3) can be used at any time, which is convenient for the auto repair personnel to perform related operations. During the operation, if the clamping protection device (12) is not needed, the internal thread locking sleeve A (16) and the internal thread locking sleeve B (24) are rotated to separate them from the anti-slip block A (17) and the anti-slip block B (23), and the metal clamping strip A (18) and the metal clamping strip B (22) can be rotated to a downward vertical state through the sleeve hole, which will not hinder the operation of the auto repair personnel. After the operation is completed, the clamping protection device (12) is reversed to restore it to its initial state for the next use.
