Description

Technical Field

[0001] The present application relates to the field of electric vehicle technology, and in particular to an electric vehicle frame structure with high battery safety. Background Art

[0002] With the development of technology, electric vehicles have become an essential means of transportation in our daily lives. Especially in first- and second-tier cities and some individual cities, due to the ban on motorcycles, electric bicycles and electric motorcycles have been widely used, which are more environmentally friendly. At the same time, the safety of electric vehicle batteries is crucial for electric vehicles. Ensuring battery safety can prevent lead-acid batteries and lithium batteries from catching fire or exploding more easily during use.

[0003] During the driving process of common electric vehicles, they are too bumpy or involved in traffic accidents, causing the part where the battery is stored to be impacted. Without buffering, the battery is prone to catch fire or explode, resulting in economic losses to the riders and affecting the safety of the riders. Utility Model Content

[0004] In order to improve the safety of the battery in the electric vehicle, the present application provides an electric vehicle frame structure with high battery safety.

[0005] An electric vehicle frame structure with high battery safety provided by the present application adopts the following technical solutions:

[0006] An electric vehicle frame structure with high battery safety includes a main body of the electric vehicle frame. A placement box is provided on the main body of the electric vehicle frame. A battery body is arranged in the placement box. Buffer components are arranged on opposite sides of the battery body. A number of fixing blocks are arranged on opposite sides of the battery body. The buffer components correspond to the fixing blocks one by one. The buffer component includes a limiting block and a compression spring. A through hole for the limiting block to pass through is formed on the fixing block. The fixing block slides along the length direction of the limiting block. One end of the limiting block is arranged on the inner wall of the placement box. The compression spring is sleeved on the limiting block. The elastic force direction of the compression spring is vertical.

[0007] By adopting the above technical solutions, the battery body is arranged in the placement box. The limiting block makes the sliding of the battery body stable. When the electric vehicle is bumpy or the placement box is impacted, the compression spring drives the battery body to slide through the compression spring, so that the battery body is not easily damaged in the placement box due to bumps or impacts on the placement box. The battery body is not prone to catch fire or explode, and the safety of the battery in the electric vehicle is improved.

[0008] Optionally, an anti-detachment block is arranged on the limiting block. The outer diameter of the anti-detachment block is larger than the outer diameter of the compression spring. One end of the compression spring is arranged on the fixing block, and the other end is arranged on the surface of the anti-detachment block close to the fixing block.

[0009] By adopting the above technical solution, the anti-disengagement block limits the distance that the compression spring drives the battery body to slide, preventing the battery body from sliding too far and disengaging from the placement box.

[0010] Optionally, stabilizing blocks are provided on the opposite inner walls of the placement box.

[0011] By adopting the above technical solution, when the electric vehicle jolts or the placement box is impacted, the elastic force of the compression spring cannot be guaranteed to be consistent. The stabilizing blocks enable the battery body to slide stably and are not prone to deviation during sliding.

[0012] Optionally, a shock-absorbing spring is provided at one end of the stabilizing block close to the battery body. The elastic force direction of the shock-absorbing spring is horizontal. A connecting block is provided at the end of the shock-absorbing spring far from the stabilizing block, and the connecting block abuts against the battery body.

[0013] By adopting the above technical solution, the shock-absorbing spring can absorb the impact force of the battery body deviation and play a buffering effect.

[0014] Optionally, a sealing cover plate is provided on the top of the placement box.

[0015] By adopting the above technical solution, after the battery body is placed in the placement box, the sealing cover plate seals the placement box, with good sealing performance, and the battery body is not easily disengaged from the placement box.

[0016] Optionally, both the placement box and the sealing cover plate are made of an aluminum alloy structure with a flame-retardant effect.

[0017] By adopting the above technical solution, if the battery body is damaged and explodes and catches fire, the aluminum alloy structure with a flame-retardant effect can effectively prevent the fire from spreading too fast and improve the safety of personnel.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The buffer assembly is not likely to damage the battery body, and the battery body is not easily ignited or exploded, improving the safety of the battery in the electric vehicle;

[0020] 2. The anti-disengagement block prevents the battery body from disengaging from the placement box;

[0021] 3. The stabilizing blocks prevent the battery body from deviating during sliding. Description of the Drawings

Specific implementation mode

[0027] The following further elaborates on this application in detail with reference to the drawings and embodiments.

[0028] The embodiment of this application discloses an electric vehicle frame structure with high battery safety. Refer to Figure 1 , Figure 2 , Figure 3 , the electric vehicle frame structure with high battery safety includes the main body 1 of the electric vehicle frame. A placement box 2 is fixed on the main body 1 of the electric vehicle frame. A battery body 3 is fixed in the placement box 2. Buffer assemblies 4 are arranged on opposite sides of the battery body 3. Two fixed blocks 51 are respectively fixed on opposite sides of the bottom and top of the battery body 3. The buffer assemblies 4 correspond to the fixed blocks 51 one by one.

[0029] Refer to Figure 2 , Figure 3 , the buffer assembly 4 includes a limit block 41 and a compression spring 42. A through hole 52 for the limit block 41 to pass through is opened on the fixed block 51. The fixed block 51 slides along the length direction of the limit block 41. One end of the limit block 41 is fixed on the inner wall of the placement box 2. The compression spring 42 is sleeved on the limit block 41. The elastic force direction of the compression spring 42 is vertical. An anti - detachment block 53 is fixed on the limit block 41. The outer diameter of the anti - detachment block 53 is larger than the outer diameter of the compression spring 42. One end of the compression spring 42 is fixed on the fixed block 51, and the other end is fixed on the surface of the anti - detachment block 53 close to the fixed block 51.

[0030] Refer to Figure 1 , Figure 3 , Figure 4 , stabilizing blocks 6 are fixed on opposite inner walls of the placement box 2. A shock - absorbing spring 7 is fixed at one end of the stabilizing block 6 close to the battery body 3. The elastic force direction of the shock - absorbing spring 7 is horizontal. One end of the shock - absorbing spring 7 far from the stabilizing block 6 is fixed with a connecting block 8, and the connecting block 8 abuts against the battery body 3.
