[0023] Specifically, during the maintenance of the power battery pack, the difficulties in loading, unloading, adjusting and repairing operations are mainly reflected in the fact that a lot of time and manpower are required, and there are safety hazards. In order to solve these problems, the present application proposes to simplify the loading, unloading and adjustment process of the power battery pack by combining the lifting device 2 and the flipping device 3. The lifting device 2 realizes the vertical movement of the power battery pack through the cooperation of the lifting plate 21 and the lifter 22, thereby reducing the manpower burden. The flipping device 3 realizes the flipping operation of the power battery pack through the cooperation of the flipping frame 31 and the motor 32, thereby ensuring the stability and safety of the battery pack during the flipping process.

[0024] As can be seen from the above, the power battery pack maintenance stand proposed in this application effectively solves the problem of difficult loading, unloading, adjustment and flipping operations of the power battery pack during the maintenance process through the combination of the lifting device 2 and the flipping device 3. Existing power battery maintenance stands mostly adopt a purely mechanical form, which takes a long time to operate and requires a lot of manpower, and there are safety hazards. The technical solution of this application drives the flip frame 31 through the motor 32 to realize the automatic flipping operation of the power battery pack, reducing the manpower demand and improving the operation efficiency and safety.

[0025] Continue to see Figure 3In this embodiment, the flip frame 31 includes two longitudinal rods 311 and two cross rods 312, the two longitudinal rods 311 and the two cross rods 312 form a rectangular frame structure with an inner hole 34, the two longitudinal rods 311 are rotatably connected to the platform body 1, the two cross rods 312 are slidably connected between the two longitudinal rods 311, the spacing between the two cross rods 312 is slidably adjusted, and a locking piece for fixing each other is provided between the longitudinal rods 311 and the cross rods 312. The flip frame 31 is composed of two longitudinal rods 311 and two cross rods 312, forming a rectangular frame structure with an inner hole 34, and this design provides a stable structural foundation. The two longitudinal rods 311 are rotatably connected to the platform body 1, so that the entire frame can be flipped. The sliding connection and spacing adjustment function between the cross rods 312 and the longitudinal rods 311 enable the frame to flexibly adapt to power battery packs of different sizes. The locking piece provides a fixing mechanism to ensure the stability of the frame after adjustment. Through the combination of these technical features, the stability and flexibility adjustment of the flip frame 31 are achieved.

[0026] In this embodiment, sleeves 313 are provided at both ends of the cross bar 312, and the sleeves 313 are slidably connected to the longitudinal bar 311. The sleeves 313 are provided at both ends of the cross bar 312, and the sleeves 313 are slidably connected to the longitudinal bar 311, so that the sliding connection of the cross bar 312 on the longitudinal bar 311 can be achieved, thereby facilitating the adjustment of the position of the cross bar 312 and ensuring that the connector 33 can accurately fix the power battery pack. This design simplifies the adjustment process of the cross bar 312, reduces the difficulty of operation, and improves the maintenance efficiency. The sleeve 313 can be made of a variety of materials, such as metal or high-strength plastic, to ensure its durability and reliability during use. The interior of the sleeve 313 can be designed as a sliding fit structure that matches the external shape of the longitudinal bar 311 to ensure the smoothness and stability of the sliding process.

[0027] In the present embodiment, the two ends of the longitudinal rod 311 are provided with anti-dropping blocks 314 for abutting against the sliding sleeve 313. The anti-dropping blocks 314 are used to prevent the sliding sleeve 313 from slipping off the longitudinal rod 311, ensuring the stability and safety of the cross bar 312 on the longitudinal rod 311, thereby solving the problem of the sliding sleeve 313 falling off. The anti-dropping blocks 314 can adopt a variety of structural forms, for example, they can be a block structure fixed to the two ends of the longitudinal rod 311 by screws, or they can be a convex part integrally formed with the longitudinal rod 311. The material of the anti-dropping blocks 314 can be selected from metal, plastic, etc., and the specific selection can be adjusted according to actual needs. The size and shape of the anti-dropping blocks 314 can also be designed according to the size and shape of the sliding sleeve 313 to ensure that it can effectively abut against the sliding sleeve 313 to prevent slipping.

[0028] In this embodiment, the locking member includes a locking screw, which is threaded on the sleeve 313 and abuts against the longitudinal rod 311. By setting the locking screw, the fixation between the sleeve 313 and the longitudinal rod 311 is achieved, thereby solving the problem of fixing the cross bar 312 and the longitudinal rod 311 of the power battery pack maintenance stand during the maintenance process. Through the action of the locking screw, the sleeve 313 can be effectively prevented from sliding on the longitudinal rod 311, ensuring a stable connection between the cross bar 312 and the longitudinal rod 311 during the maintenance process, thereby improving the safety and efficiency of the operation. The locking screw can be implemented in a variety of ways, such as using a standard threaded screw, or a screw with an anti-loosening design, to ensure that a stable locking effect can be maintained during long-term use.

[0029] In this embodiment, at least one connector 33 is provided on the crossbar 312, and the connector 33 is slidably connected to the crossbar 312 along the length direction of the crossbar 312. The connector 33 is allowed to slide freely on the crossbar 312, so that the position of the connector 33 can be adjusted as needed. This design can easily adjust the position of the connector 33 to adapt to power battery packs of different sizes and shapes, thereby improving the flexibility and applicability of the maintenance bench. At least one connector 33 is provided on the crossbar 312, wherein the connector 33 is connected to the crossbar 312 through a sliding mechanism. The sliding mechanism can be implemented in the form of a slide rail, a slider or a roller. For example, the slide rail can be set on the side of the crossbar 312, and the connector 33 cooperates with the slide rail through a slider so that it can slide along the length direction of the crossbar 312. As a preferred embodiment, the sliding mechanism may also include a locking device for fixing the connector 33 after it slides to a predetermined position to prevent accidental movement during operation. The connector 33 is a bolt fastener.

[0030] Continue to see Figure 2 and Figure 4 In this embodiment, a speed reduction mechanism is also installed on the gantry body 1, and the input end of the speed reduction mechanism is connected to the rotating shaft of the motor 32, and the output end of the speed reduction mechanism is connected to the flip frame 31. By installing the speed reduction mechanism on the gantry body 1, the rotating shaft of the motor 32 transmits power to the flip frame 31 through the speed reduction mechanism, which can effectively control the rotation speed of the flip frame 31 and provide sufficient torque to flip the power battery pack safely and stably. The setting of the speed reduction mechanism enables the motor 32 to drive the flip frame 31 at a lower speed and higher torque, thereby solving the speed control and torque transmission problems of the power battery pack maintenance gantry during the flipping process, and improving the safety and efficiency of the maintenance operation.

[0031] In this embodiment, the reduction mechanism is a gear reduction mechanism 4, which includes a sun gear 41, a star gear 42 and an inner gear ring 43. The sun gear 41 is fixedly connected to the rotating shaft of the motor 32, and the star gear 42 is meshed between the sun gear 41 and the inner gear ring 43. The inner gear ring 43 is fixedly connected to the flip frame 31. Through such a structural design, the high-speed rotation of the motor 32 is decelerated by the gear reduction mechanism 4 and then transmitted to the flip frame 31, so that the flip frame 31 can be flipped at a lower speed, thereby solving the deceleration problem when the motor 32 drives the flip frame 31, and ensuring the stability and safety of the flip operation. Specifically, the implementation of the gear reduction mechanism 4 may include the following variants: First, the sun gear 41 may be made of high-strength alloy material to improve its wear resistance and service life. Secondly, the number of teeth of the star gear 42 can be adjusted according to actual needs to change the reduction ratio to meet different flip speed requirements. The inner gear ring 43 can also be modularly designed for easy replacement and maintenance. In addition, the lubrication system of the gear reduction mechanism 4 can adopt an automatic lubrication device to reduce the maintenance workload and extend the service life.

[0032] Continue to see Figure 1 In this embodiment, a movable universal wheel 5 is provided at the bottom of the stand body 1. By providing the movable universal wheel 5 at the bottom of the stand body 1, the stand body 1 can be conveniently moved, thereby solving the problem of the inconvenient movement of the power battery pack maintenance stand. By increasing the mobility of the stand, the maintenance operation of the power battery pack is made more flexible and convenient, the use of manpower is reduced, and the work efficiency and safety are improved. The setting of the movable universal wheel 5 can be implemented in a variety of ways. For example, the universal wheel can be made of high-strength material to ensure sufficient strength and durability when carrying the weight of the power battery pack. Furthermore, the universal wheel can be equipped with a brake device to fix the stand when necessary to increase the safety of the operation. As a preferred embodiment, the universal wheel can be fixed to the bottom of the stand body 1 by bolts or welding to ensure its stability and reliability.
