[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Example:

[0031] Please combine Figure 1-5 , a conveniently assembled automotive power battery pack assembly of this embodiment includes an assembly table 1, an auxiliary groove 2 is opened in the middle of the upper surface of the assembly table 1, a positioning component 3 is arranged inside the auxiliary groove 2, and a battery pack module 4 is arranged on the upper surface of the assembly table 1;

[0032] The positioning assembly 3 includes a movable slider 301, which is slidably connected to both sides of the auxiliary groove 2, and a positioning clamp 302 is fixedly connected to the top of the movable slider 301. The positioning clamp 302 is slidably connected to the upper surface of the assembly table 1 through the movable slider 301. A positive and negative threaded rod 303 is arranged inside the movable slider 301. One end of the positive and negative threaded rod 303 is rotatably connected to the inner wall of the auxiliary groove 2 through a bearing, and the other end of the positive and negative threaded rod 303 is fixedly connected to an operating handle 304. Through the design of the positioning clamp 302, the battery pack module 4 can be accurately positioned. For positioning and fixing, the movable slider 301 can slide in the auxiliary groove 2, so that the positioning clamp 302 can adapt to battery pack modules 4 of different sizes and shapes. The battery pack module 4 is firmly fixed on the assembly table 1 during the assembly process, reducing the risk of assembly errors due to instability, making the assembly process of the battery pack module 4 simpler and faster, and helping to improve work efficiency on the production line. By using the forward and reverse threaded rods 303 to control the movement of the movable slider 301, precise positioning can be achieved, and the threaded connection also provides better rigidity and repeatability. Positioning accuracy.

[0033] There are three battery pack modules 4, which are respectively arranged on both sides and the middle of the upper surface of the assembly table 1. The symmetrical distribution of the three battery pack modules 4 helps to improve the stability and balance of the entire system and reduce the safety hazards caused by unstable center of gravity during the assembly process.

[0034] Both sides of the outer surface of the battery pack module 4 are fixedly connected with a connecting sleeve 5, and an assembly rod 6 is arranged inside the connecting sleeve 5. The combination of the connecting sleeve 5 and the assembly rod 6 can enhance the stability of the battery pack module 4 and prevent displacement or overturning during the assembly process. The assembly rod 6 can provide additional structural support to improve the overall strength of the battery pack module 4 so that it can withstand greater pressure and impact.

[0035] Both ends of the assembly rod 6 are threadedly connected with hexagonal bolts 7. When the battery pack module 4 needs to be maintained or replaced, the hexagonal bolts 7 can be quickly unscrewed to disassemble the assembly rod 6 and the battery pack module 4.

[0036] A protective shell 8 is provided on the top of the battery pack module 4, and a limit pin 9 is provided on the upper surface of the protective shell 8. The protective shell 8 can protect the battery pack module 4 from external impact, scratches and pollution, thereby extending the service life of the battery pack.

[0037] There are four limit pins 9, which are respectively arranged at the four corners of the upper surface of the protective shell 8. The limit pins 9 are arranged at the four corner points so that the force applied to the protective shell 8 can be evenly distributed in all directions, thereby improving the overall stability. The four limit pins 9 are convenient for the operator to operate from four directions at the same time, simplifying the installation and disassembly process and improving work efficiency.

[0038] The top of the limit pin 9 is engraved with an external thread, the bottom of the limit pin 9 is set on the surface of the battery pack module 4, and the top of the limit pin 9 is threadedly connected with a positioning ring 10. Through the moderate tightening of the positioning ring 10, the limit pin 9 can be prevented from being damaged due to excessive tightening and the battery pack module 4 from being loosened due to excessive loosening.

[0039] The implementation principle of an automobile power battery pack assembly that is convenient to assemble in the embodiment of the present application is as follows: a person first places the battery pack module 4 to be assembled on the surface of the assembly table 1, and then rotates the operating handle 304 to rotate the positive and negative threaded rod 303. Since the threads engraved on both sides of the positive and negative threaded rod 303 are opposite, the positioning clamp 302 moves toward the middle to clamp and position the battery pack module 4. The movable slider 301 can slide in the auxiliary groove 2, so that the positioning clamp 302 can adapt to battery pack modules 4 of different sizes and shapes. The battery pack module 4 is firmly fixed on the assembly table 1 during the assembly process, reducing the risk of assembly errors caused by instability, making the assembly process of the battery pack module 4 simpler. It is simple and fast, which helps to improve the work efficiency on the production line. By using the positive and negative threaded rods 303 to control the movement of the movable slider 301, precise positioning can be achieved. At the same time, the threaded connection also provides good rigidity and repeatable positioning accuracy. The combination of the connecting sleeve 5 and the assembly rod 6 can enhance the stability of the battery pack module 4 and prevent displacement or overturning during the assembly process. The assembly rod 6 can provide additional structural support to improve the overall strength of the battery pack module 4 and enable it to withstand greater pressure and impact. The top of the limit pin 9 is threadedly connected with a positioning ring 10. Through the moderate tightening of the positioning ring 10, the battery pack module 4 caused by excessive tightening of the limit pin 9 can be prevented from being damaged, or the battery pack module 4 caused to be loose due to excessive loosening.
