[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 6 As shown, the utility model provides a battery module anti-collision tooling, which is applied to a battery module body 1, comprising:

[0026] A clamping assembly, which is arranged on the battery module body 1 and is used to fix different battery module bodies 1;

[0027] Among them, the adjustment component includes a splint 2, which is distributed at the corners of the battery module body 1. A connecting rod 3 is installed on the outside of the splint 2, and a mounting frame 4 is installed on the end of the connecting rod 3. A round rod 5 is sleeved inside the mounting frame 4, and a movable frame 6 is sleeved on one side of the mounting frame 4. A threaded rod 8 is threadedly connected to the outside of the movable frame 6, and a pressure block 7 is connected to the end of the movable frame 6. The outer surface of the round rod 5 is connected to a mounting shaft 9, and a cylinder 10 and a movable rod 11 are respectively installed on the outside of the two mounting shafts 9 on one side, and a rotating shaft 12 is threadedly connected between the two mounting shafts 9 on the other side.

[0028] The mounting frame 4 can be moved along the outer surface of the round rod 5, so that the distance between the two adjacent clamps 2 can be controlled by the connecting rod 3. At the same time, through the cooperation between the threaded rod 8 and the movable frame 6, the threaded rod 8 will drive the movable frame 6 to move along the inner side of the mounting frame 4 when rotating, so that the pressure block 7 can be driven to squeeze the outer surface of the round rod 5, and then the movement of the connecting rod 3 and the round rod 5 can be limited, so as to facilitate the control of the clamp 2 to move to the corners of the battery module body 1. At the same time, through the cooperation between the rotating shaft 12 and the mounting shaft 9, and the cooperation between the movable rod 11 and the cylinder 10, when the rotating shaft 12 rotates, it will drive the two mounting shafts 9 to move toward or away from each other, so that it can clamp the battery module bodies 1 of different thicknesses, and then it can be installed on battery module bodies 1 of different sizes, thereby improving its scope of application.

[0029] A notch 13 is provided inside the clamping plate 2 , a return spring 14 and a round block 15 are sleeved inside the notch 13 , a connecting shaft 16 is installed on one side of the round block 15 , and a protective plate 17 is installed on the end of the connecting shaft 16 .

[0030] Through the cooperation between the round block 15 and the slot 13, the round block 15 can move along the inner wall of the slot 13, and the round block 15 will be supported by the elastic force of the return spring 14. When the protective plate 17 is squeezed, the round block 15 will be driven by the connecting shaft 16 to compress the return spring 14, so that the return spring 14 will absorb the impact force, and the friction force between the round block 15 and the slot 13 will form friction damping, so that it consumes the elastic force released by the return spring 14.

[0031] The clamping plate 2 is in press contact with the battery module body 1 , and the pressing block 7 is in press contact with the round rod 5 .

[0032] Through the cooperation between the clamping plate 2 and the battery module body 1, the battery module body 1 can be clamped by the clamping plate 2 at the corners, and at the same time, through the cooperation between the pressing block 7 and the round rod 5, the mounting frame 4 and the round rod 5 will be positioned, thereby limiting the movement of the clamping plate 2.

[0033] The end of the threaded rod 8 is in press contact with the mounting frame 4 , and the mounting frame 4 is in press contact with the outer side of the battery module body 1 .

[0034] Through the cooperation between the threaded rod 8 and the movable frame 6, the threaded rod 8 will move along the inside of the movable frame 6. When the threaded rod 8 squeezes the mounting frame 4, it will drive the movable frame 6 to move along the inside of the mounting frame 4, so that the movable frame 6 can drive the pressing block 7 to squeeze the outer surface of the round rod 5, so that the position of the connecting rod 3 and the mounting frame 4 can be adjusted, so that several groups of mounting frames 4 can be controlled to clamp the outer side of the battery module body 1.

[0035] The outer surface of the rotating shaft 12 is provided with two sections of threads, the directions of the two sections of threads are opposite and are located at two ends of the rotating shaft 12 .

[0036] By setting two opposite threads on the outer surface of the rotating shaft 12, the rotating shaft 12 will drive the two sets of mounting shafts 9 to move toward or away from each other when rotating, so as to control the distance between the upper and lower sets of clamping plates 2 to adapt to battery module bodies 1 of different sizes.

[0037] The cylinder 10 is sleeved with the movable rod 11 .

[0038] Through the cooperation between the cylinder 10 and the movable rod 11 , the movable rod 11 will move up and down along the inner wall of the cylinder 10 when the rotating shaft 12 rotates.

[0039] The return spring 14 is elastically supported between the notch 13 and the round block 15 .

[0040] The design of the return spring 14 allows the round block 15 to have good elastic return performance. At this time, since the return spring 14 is in a compressed state, an elastic force is applied to the round block 15 , so that the protective plate 17 can be supported through the connecting shaft 16 .

[0041] The outer surface of the round block 15 is rough, and the outer surface of the protective plate 17 is bonded with rubber.

[0042] Through the design of the round block 15, since the outer surface of the round block 15 is rough, the friction between the round block 15 and the notch 13 can be controlled to form friction damping, thereby offsetting a part of the force absorbed by the return spring 14, and playing a buffering role when impacted.

[0043] The working principle and use process of this utility model:

[0044] Through the cooperation between the mounting frame 4 and the round rod 5, the mounting frame 4 can be moved along the outer surface of the round rod 5, so that the distance between the two adjacent clamps 2 can be controlled by the connecting rod 3. After the clamps 2 move to the edge of the battery module body 1, the staff can rotate the threaded rod 8. When the threaded rod 8 rotates, it will drive the movable frame 6 to move along the inner side of the mounting frame 4, thereby driving the pressure block 7 to squeeze the outer surface of the round rod 5 to limit the clamps 2, and clamp the outer side of the battery module body 1 through the mounting frame 4. Then the staff can rotate the rotating shaft 12. Through the cooperation between the rotating shaft 12 and the mounting shaft 9, and the cooperation between the movable rod 11 and the cylinder 10, when the rotating shaft 12 rotates, it will drive the two mounting shafts 9 to move toward or away from each other, so that it can drive the clamps 2 to clamp the battery module bodies 1 of different thicknesses, and then it can be installed on battery module bodies 1 of different sizes, thereby improving its scope of application.
