The curved beams 2 include a beam body 203. Both sides of the beam body 203 are tilted downward. The middle portion of the beam body 203 is provided with an upwardly curved arc structure 201. The upward deformation force of the arc structure 201 is used to counteract the downward pressure of the battery module. Extension plates 202 are integrally provided on both sides of the beam body 203. The top of the extension plate 202 is fixedly connected to the outer side of the liquid cooling plate 1 by a locking mechanism 3 for connection and fixation.

[0022] The liquid cooling plate 1 includes a plate body 100, and a plurality of circular plates 101 fixedly mounted on the bottom of the plate body 100. The sides of two adjacent circular plates 101 close to each other are buckled together, wherein the sides of two adjacent circular plates 101 close to each other are fixedly connected with L-shaped clips 103, and the two adjacent L-shaped clips 103 are symmetrically arranged and buckled with each other. The connection between the two adjacent circular plates 101 is achieved by the corresponding two L-shaped clips 103. The bottom of the L-shaped clip 103 located in the middle is in movable contact with the top of the corresponding arc-shaped structure 201, and the top of the arc-shaped structure 201 is in movable contact with the bottom of the corresponding circular plate 101 located in the middle. The sides of the two circular plates 101 located on both sides that are away from each other are integrally provided with outer edges 102.

[0023] The locking mechanism 3 includes a double-headed T-shaped bolt 301, and a square nut 304 is fixedly installed at the bottom of the extension plate 202. The double-headed T-shaped bolt 301 is threadedly sleeved in the corresponding square nut 304, and the outer edge 102 is movably sleeved on the corresponding double-headed T-shaped bolt 301, wherein the top of the outer edge 102 is provided with a movable hole, the double-headed T-shaped bolt 301 is located in the corresponding movable hole and movably contacts the inner wall of the movable hole, the top inner wall of the double-headed T-shaped bolt 301 is movably contacted with the top of the corresponding outer edge 102, and the bottom of the outer edge 102 is movably contacted with a pad 302 threadedly sleeved on the corresponding double-headed T-shaped bolt 301, wherein the top of the pad 302 is provided with a bolt hole, and the bolt hole is threadedly connected to the corresponding double-headed T-bolt 301, and the pad 302 rotates The screw thread on the stud 301 is provided with a first nut 303 located above the corresponding outer edge 102, and the first nut 303 is reserved for use when assembling the box cover. The square nut 304, the stud 301 and the screw thread on the stud 302 cooperate with the spacer 302 to realize the connection and fixation between the liquid cooling plate 1 and the curved beam 2; the utility model utilizes the pre-bent deformation force of the arc structure 201 on the curved beam 2 provided at the bottom to resist the downward pressure of the battery module, so that the deformation of the liquid cooling plate 1 is effectively controlled. Compared with the prior art method of relying solely on increasing the thickness of the material itself to bear the load, this solution is both clever and cost-effective, and meets the use requirements.

[0024] Working principle: When the bending beam 2 and the liquid cooling plate 1 are not assembled, the liquid cooling plate 1 is placed on the top of the bending beam 2. At this time, the arc structure 201 on the bending beam 2 is in active contact with the circular plate 101 and the L-shaped buckle 103 in the middle of the liquid cooling plate 1. At the same time, the stud T-bolt 301 is screwed into the corresponding square nut 304. Then, the stud T-bolt 301 is continued to be rotated. While rotating, the stud T-bolt 301 moves downward until its top inner wall contacts the top of the corresponding outer edge 102. Then, the support height of the pad 302 is adjusted according to the curvature of the bending beam 2. During adjustment, the corresponding pad 302 is rotated in the forward direction. The pad 30 rotates and moves upward on the corresponding stud T-bolt 301, so that the top of the pad 302 gradually contacts the corresponding outer edge 102. At this time, the pad 302 is used to The bottom of the outer edge 102 is supported, and the connection between the curved beam 2 and the two sides of the liquid cooling plate 1 is tightened by cooperating with the square nut 304, the stud T-bolt 301 and the spacer 302. At this time, the curved beam 2 has an upward supporting force on the liquid cooling plate 1, and the first nut 303 is reserved for use when assembling the box cover. After the battery module is assembled, the liquid cooling plate 1 is subjected to downward pressure. The downward pressure and the upward supporting force of the curved beam 2 on the liquid cooling plate 1 are neutralized to a certain extent, so that the deformation of the liquid cooling plate 1 is reduced, which can effectively reduce the situation where the liquid cooling plate 1 is greatly deformed during use. In addition, this method uses the pre-bent deformation force of the curved beam 2 itself to counteract the downward pressure of the battery module, so that the deformation of the liquid cooling plate 1 is effectively controlled. Compared with the existing method of relying solely on increasing the thickness of the material itself to bear the load, its cost is significantly reduced.

[0025] In addition, the pre-bending parameters of the arc structure 201 on the curved beam 2 are determined by simulation using mechanical simulation software. For example, if the weight of the battery is set to 350KG, the liquid cooling plate 1 below the battery will be deformed by 3mm under pressure. At this time, the bottom curved beam 2 is added. The curved beam 2 offsets the downward pressure of the battery, thereby reducing the deformation of the liquid cooling plate 1. By adjusting the upward bending parameters of the arc structure 201 on the curved beam 2, the deformation of the liquid cooling plate 1 can be controlled within 1mm.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, including but not limited to the structural form, material, thickness, etc. of the curved beam, which should be covered within the protection scope of the present invention.
