[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-4The water cooling unit for the truck power battery assembly shown includes a water cooling unit 1, a plurality of mounting blocks 2 are symmetrically arranged at the bottom of the water cooling unit 1, and bolts 3 for fixing the position of the water cooling unit 1 are inserted through the middle of the mounting blocks 2.

[0021] The limiting component 4 is used to limit the movement of the bolt 3. The limiting component 4 includes a positioning block 401 fixedly connected to the top of the mounting block 2. A limiting ring 402 is sleeved on the middle part of the bolt 3. A pressing block 405 for pressing the limiting ring 402 is provided on the top of the positioning block 401.

[0022] It should be noted that the water-cooling unit 1 is an existing water-cooling unit. When in use, a fan is used to pass air through the cooler to take away the heat generated during the refrigeration process. When the position of the water-cooling unit 1 needs to be fixed, the position of the water-cooling unit 1 is first moved to the desired position so that the mounting block 2 at the bottom of the water-cooling unit 1 is fitted with the power battery frame. A hole for the bolt 3 to pass through is opened in the middle of the mounting block 2. When the position of the mounting block 2 needs to be fixed, the position of the mounting block 2 is fixed by the bolt 3.

[0023] Specifically, a sliding groove 403 is provided at the top of the positioning block 401, and the limiting ring 402 is inserted and connected inside the sliding groove 403. A through hole 404 is provided in the middle of the pressing block 405, and the bolt 3 is inserted and connected inside the through hole 404. A through hole is provided on the inner wall of the bottom end of the sliding groove 403, and the bolt 3 is inserted and connected inside the through hole. A fixing component 5 is provided at the connection between the pressing block 405 and the positioning block 401, and the fixing component 5 is used to fix the position of the pressing block 405.

[0024] It should be noted that the positioning block 401 is fixed to the top of the mounting block 2 by welding; the limiting ring 402 is annular and is fixed to the middle of the bolt 3 by welding when in use. The sliding groove 403 opened at the top of the positioning block 401 is adapted to the limiting ring 402, so that the limiting ring 402 can slide inside the sliding groove 403; the through-hole opened at the bottom end of the sliding groove 403 is interconnected with the hole opened on the mounting block 2, so that the bottom end of the bolt 3 can pass through the mounting block 2; the diameter of the through-hole is smaller than the outer diameter of the limiting ring 402, so that the limiting ring 402 cannot pass through the sliding groove 403 through the through-hole, and the pressing block 405 is used to limit the upward movement of the limiting ring 402, and the pressing block 405 is used to limit the moving distance of the limiting ring 402 and the bolt 3 to avoid the bolt 3 from moving at will.

[0025] Specifically, the fixing component 5 includes a connecting block 502 that is centrally and symmetrically fixedly connected to the bottom end of the pressing block 405, and a clamping block 503 for fixing the position of the pressing block 405 is provided on one side of the connecting block 502. A plurality of connecting grooves 501 are centrally and symmetrically provided on the top of the positioning block 401. The connecting block 502 is inserted and connected to the inside of the connecting groove 501, and a clamping hole 505 is provided on the inner wall of one side of the connecting groove 501. The clamping block 503 is inserted and connected to the inside of the clamping hole 505, and an inclined groove 504 is provided at the bottom of the clamping block 503.

[0026] It should be noted that the connecting block 502 is made of a deformable material, such as plastic. When the position of the pressing block 405 needs to be fixed, the pressing block 405 is first moved to the top of the positioning block 401, and the connecting block 502 at the bottom of the pressing block 405 is aligned with the connecting groove 501 opened at the top of the positioning block 401, and the connecting block 502 is inserted into the interior of the connecting groove 501. When the inclined groove 504 at the bottom of the clamping block 503 is pressed against the inner wall of one side of the connecting groove 501, the connecting block 502 will be squeezed and deformed, so that the connecting block 502 and the clamping block 503 are both inserted into the interior of the connecting groove 501, and the connecting block 502 is continued to be moved. 02, when the clamping block 503 on one side of the connecting block 502 moves to align with the clamping hole 505, the connecting block 502 recovers its deformation and moves the clamping block 503 to the inside of the clamping hole 505, and fixes the position of the connecting block 502 by the clamping block 503, and fixes the position of the pressing block 405 by the connecting block 502 in the fixed position; when it is necessary to remove the pressing block 405 from the top of the positioning block 401, press the clamping block 503 out of the clamping hole 505, continue to move the pressing block 405, and move the connecting block 502 and the clamping block 503 out of the connecting groove 501 together, so as to remove the pressing block 405 from the positioning block 401.
