[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0021] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0022] refer to Figure 1-3 A new energy vehicle battery box body with anti-collision function comprises a battery box body 1, a reinforcing beam 2 is arranged inside the battery box body 1, a plurality of threaded holes are opened on the upper end surface of the reinforcing beam 2, a car battery body 3 is arranged on the upper end surface of the reinforcing beam 2, both sides of the car battery body 3 are fixedly connected with L-shaped connecting blocks 4, and the two L-shaped connecting blocks 4 are fixedly connected to the reinforcing beam 2 by two bolts matching the threaded holes, an anti-collision frame 5 is slidably connected to the side wall of the battery box body 1, four supporting steel beams 6 are fixedly connected to the inner wall of the anti-collision frame 5, and the upper end surfaces of the four supporting steel beams 6 are welded to the lower end surface of the battery box body 1, and a top frame cover 7 is arranged on the upper end surface of the anti-collision frame 5, and screw holes are opened on the top frame cover 7 and the side walls of the anti-collision frame 5, and the top frame cover 7 is fixedly connected to the anti-collision frame 5 by a plurality of screws matching the screw holes.

[0023] By providing the anti-collision frame 5 and the supporting steel beam 6, the anti-collision frame 5 and the four supporting steel beams 6 can protect the automobile battery body 3 from the bottom impact after the automobile battery body 3 is installed in the battery box body 1, thereby improving the protection capability of the battery box body 1 for the automobile battery body 3 installed on the reinforcing beam 2;

[0024] Furthermore, a plurality of buffer springs 9 are fixedly connected at equal intervals on the inner wall of the top frame cover 7 , and a buffer block 10 is fixedly connected to the lower end surfaces of the plurality of buffer springs 9 .

[0025] By providing a plurality of buffer springs 9 and buffer blocks 10, when the lower end of the anti-collision frame 5 is deformed and the four supporting steel beams 6 lift the battery box body 1 upward, the vehicle battery body 3 will lift the buffer block 10 in the direction of the plurality of buffer springs 9 and compress the plurality of buffer springs 9. The plurality of buffer springs 9 and the buffer block 10 can make the vehicle battery body 3 rigidly collide with the top frame cover 7 when being lifted, so as to further protect the vehicle battery body 3 in the battery box body 1;

[0026] Furthermore, the buffer block 10 is a polypropylene foam board, and the buffer block 10 is rectangular.

[0027] By setting the buffer block 10 as a polypropylene foam board, the polypropylene foam has good toughness and shock absorption performance, which can reduce the friction between the vehicle battery body 3 and the surface of the buffer block 10 when the vehicle battery body 3 contacts the buffer block 10;

[0028] Furthermore, the four supporting steel beams 6 are all H-shaped, and the four supporting steel beams 6 are all carbon structural steel beams.

[0029] By setting the four supporting steel beams 6 as H-shaped carbon structural steel beams, the H-shape enables each part of the supporting steel beam 6 to be arranged at right angles, so that the four supporting steel beams 6 have high-strength bending resistance in all directions, and the structural strength of the four supporting steel beams 6 is higher;

[0030] Furthermore, the reinforcing beam 2 is a carbon alloy steel beam, and the reinforcing beam 2 is welded to the inner wall of the battery box body 1 .

[0031] By setting the reinforcing beam 2 welded to the inner wall of the battery box body 1 as a carbon alloy steel beam, the carbon alloy steel beam has good weldability and high strength and hardness, which is more conducive to the welding of the reinforcing beam 2 in the battery box body 1;

[0032] Furthermore, two ventilation holes 8 are provided on the upper end surface of the top frame cover 7 , and the anti-collision frame 5 and the top frame cover 7 are both connected to the outside through the two ventilation holes 8 .

[0033] By providing two ventilation strip holes 8 , the inner cavity formed by the anti-collision frame 5 and the top frame cover 7 can be connected to the outside air, so that the heat generated by the vehicle battery body 3 during operation can be dissipated outwards through the two ventilation strip holes 8 .

[0034] Working principle of the utility model: after the automobile battery body 3 is fixedly installed on the reinforcing beam 2 by two L-shaped connecting blocks 4 through the cooperation of bolts and threaded holes, when the bottom of the automobile is violently bumped, the impact from the lower end of the battery box body 1 will first hit the anti-collision frame 5 on the outside of the battery box body 1, and the anti-collision frame 5 absorbs the impact force and deforms while resisting the impact, so that the lower end of the anti-collision frame 5 is squeezed in the direction of the battery box body 1, and at the same time, the two sides of the anti-collision frame 5 will deform in the direction away from the battery box body 1, and when the lower end of the anti-collision frame 5 is squeezed in the direction of the battery box body 1, the four supporting steel beams 6 will lift the position of the battery box body 1 in the anti-collision frame 5 toward the direction of the top frame cover 7, so that the automobile battery body 3 is as far away as possible from the lower end of the anti-collision frame 5 that is deformed due to the impact, so as to achieve the purpose of protecting the automobile battery body 3;

[0035] Compared with the prior art, by providing an anti-collision frame 5 and a supporting steel beam 6, after the automobile battery body 3 is installed in the battery box body 1, the anti-collision frame 5 and the four supporting steel beams 6 can resist the impact from the bottom, thereby improving the protection capability of the battery box body 1 for the automobile battery body 3 installed on the reinforcing beam 2.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
