[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4As shown, a flexible connection power battery pack busbar structure includes a battery body 1 and a protective cover 2. A connection auxiliary mechanism 5 is provided at the upper end of the protective cover 2. The connection auxiliary mechanism 5 includes a guide frame 51 fixedly connected to the upper end of the protective cover 2. A contact rod 52 is installed inside the guide frame 51. A sliding groove 53 is opened at one end of the guide frame 51. A moving frame 54 is slidably connected to the outer side of the guide frame 51. A contact block 55 is slidably connected to the inner side of the sliding groove 53. A mounting frame 56 is fixedly connected to the upper end of the moving frame 54. A winding rod 57 is slidably connected to the inner side of the mounting frame 56. A first internal thread ring 59 is threaded on the outer side of the winding rod 57 near the mounting frame 56. A connecting groove 58 is opened on the outer side of the winding rod 57 near the first internal thread ring 59. A second internal thread ring 510 is threadedly connected to the other outer side of the winding rod 57 near the mounting frame 56.

[0015] In this embodiment, one end of the winding rod 57 is fixedly connected to a baffle 511. The contact rod 52 penetrates the interior of the protective cover plate 2 and is fixedly connected to the protective cover plate 2. The lower end of the contact rod 52 is installed inside the battery body 1. The movable frame 54 is U-shaped. One end of the contact block 55 is fixedly connected to the inner wall of the movable frame 54. There are two sets of sliding grooves 53 and movable frames 54. One end of the first internal threaded ring 59 is in contact with one end of the mounting frame 56, and one end of the second internal threaded ring 510 is in contact with the other end of the mounting frame 56. The center lines of the winding rod 57, the first internal threaded ring 59, the second internal threaded ring 510, and the baffle 511 are located on the same straight line. There are two sets of connecting auxiliary mechanisms 5.

[0016] Specifically, by twisting the first internal threaded ring 59 and the second internal threaded ring 510, the first internal threaded ring 59 moves away from the mounting bracket 56 along the winding rod 57, and the second internal threaded ring 510 moves away from the mounting bracket 56 along the winding rod 57. Then, by pushing the winding rod 57, the winding rod 57 moves within the mounting bracket 56, thus adjusting the position of the connecting groove 58 corresponding to the battery body 1. Then, by twisting the first internal threaded ring 59 and the second internal threaded ring 510 in the opposite direction, the first internal threaded ring 59 and the second internal threaded ring 510 come into contact with the mounting bracket 56, thereby limiting the winding rod 57. Then, the wire is wound into the connecting groove 58, and the wire is wound around the surface of the winding rod 57. At the same time, the moving frame 54 is pulled, and the moving frame 54 slides along the guide frame 51, and the moving frame 54 drives the contact block 55 to slide within the sliding groove 53, thus moving the winding rod 57. The wire is moved to a suitable position and then connected to the inside of the contact rod 52, thus connecting the wire to the protective cover 2. Since the wire is wound around the outside of the winding rod 57, it is positioned above the battery body 1, preventing direct contact between the wire and the battery body 1, thereby improving the overall safety of the battery body 1. By sliding the winding rod 57 inside the mounting bracket 56 and pulling the moving bracket 54 along the guide bracket 51, the winding rod 57 moves the connecting groove 58, changing the position of the connecting groove 58 relative to the battery body 1. The wire is then wound around the connecting groove 58, so that the wire is wound around the outside of the winding rod 57, which facilitates positioning the wire above the battery body 1, suspending the wire and preventing direct contact between the wire and the battery body 1, thus improving the overall safety of the battery body 1.

[0017] In this embodiment, the protective cover 2 is installed at the upper end of the battery body 1, the lower end of the battery body 1 is equipped with a support base 3, and the front end of the battery body 1 is equipped with a stabilizing frame 4. The protective cover 2 and the support base 3 correspond to each other.

[0018] Specifically, first, the support base 3 is placed in the designated position, and the battery body 1 is positioned in the designated position. The protective cover 2 and the support base 3 protect the upper and lower ends of the battery body 1 to prevent the upper and lower ends of the battery body 1 from being impacted.

[0019] Working principle: In use, first place the support base 3 in the designated position, ensuring the battery body 1 is in the designated position, and that the protective cover 2 and support base 3 protect the upper and lower ends of the battery body 1 from impact. Then, twist the first internal thread ring 59 and the second internal thread ring 510, causing the first internal thread ring 59 to move along the winding rod 57 away from the mounting bracket 56, and the second internal thread ring 510 to move along the winding rod 57 away from the mounting bracket 56. Then push the winding rod... By winding the rod 57, the rod 57 moves within the mounting bracket 56, adjusting the position of the connecting groove 58 corresponding to the battery body 1. Then, by reversing the first internal thread ring 59 and the second internal thread ring 510, they come into contact with the mounting bracket 56, thus limiting the winding rod 57. The wire is then wound into the connecting groove 58 and onto the surface of the winding rod 57. Simultaneously, the moving bracket 54 is pulled, causing it to slide along the guide bracket 51. The moving frame 54 drives the contact block 55 to slide within the sliding groove 53, thereby moving the winding rod 57 and moving the wire to a suitable position. Then, the wire is connected to the inside of the contact rod 52, thus connecting the wire to the protective cover 2. Since the wire is wound around the outside of the winding rod 57, it is positioned above the battery body 1, preventing direct contact between the wire and the battery body 1, thus improving the overall safety of the battery body 1. By sliding the winding rod 57 inside the mounting frame 56 and pulling the moving frame 54 along the guide frame 51, the winding rod 57 moves the connecting groove 58, changing the position of the connecting groove 58 relative to the battery body 1. The wire is then wound around the connecting groove 58, so that the wire is wound around the outside of the winding rod 57, making it easy to position the wire above the battery body 1, thus suspending the wire and preventing direct contact between the wire and the battery body 1, thereby improving the overall safety of the battery body 1.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
