AI Technical Summary
Traditional port tractor battery box anti-collision structures are difficult to provide sufficient anti-collision performance while taking into account heat dissipation performance, and they are also prone to blocking heat dissipation holes, affecting heat dissipation efficiency.
A structure including a first anti-collision plate and a second anti-collision plate was designed. The impact force was absorbed by the combination of spring, slide bar and damping sleeve, and ventilation holes were set on the anti-collision plate to ensure heat dissipation and prevent the heat dissipation holes from being blocked.
This improves the impact resistance of the battery box while maintaining good heat dissipation performance, preventing the heat dissipation holes from being blocked, and enhancing the operational reliability of the battery box.

Technical Field
[0001] This utility model relates to the field of port tractor battery boxes, specifically a collision protection structure for port tractor battery boxes. Background Technology
[0002] In port operations, new energy port tractors rely on battery packs for power, and the safety and heat dissipation performance of the battery housing directly affect the reliability of vehicle operation. In the port environment, tractors need to frequently shuttle between loading and unloading areas and stacking areas, and are prone to collisions with containers, stacks of goods or other equipment. Therefore, the battery housing must have reliable collision protection capabilities. Traditional port tractor battery pack anti-collision structures mostly use integral metal protective shells or fixed anti-collision beams. While these provide some impact protection, their heavy structure and close fit to the battery pack not only increase the vehicle load but also obstruct the battery pack's heat dissipation vents, hindering heat dissipation and significantly reducing cooling efficiency. Some improved structures adopt a perforated design to balance heat dissipation, but at the expense of impact resistance, making them unable to withstand the impacts of complex port conditions. Therefore, a new anti-collision structure for port tractor battery packs is needed to solve these problems. Utility Model Content

A second push rod 13 is fixedly installed on one side of the second anti-collision plate 7 via a bracket. One side of the second push rod 13 is in contact with the surface of the second trapezoidal plate 11. A damping sleeve 14 is fixedly installed on the top of the battery box body 2. Several damping sleeves 14 are provided. A damping rod 15 is slidably connected inside the damping sleeve 14. The surface of the damping rod 15 and the surface of the damping sleeve 14 are both made of rubber. The surface of the damping rod 15 and the inner wall of the damping sleeve 14 are interference-fitted. The top of the damping rod 15 is fixedly installed at the bottom of the top plate 9. The surface of the damping rod 15 is in close contact with the inner wall of the damping sleeve 14. By setting the first anti-collision plate 6 and the second anti-collision plate 7, the first anti-collision plate 6 or the second anti-collision plate 7 can drive the sliding rod 5 to move into the sleeve 3 when it is impacted. The movement of the sliding rod 5 can compress the first spring 4, achieving the effect of absorbing the impact force for the first time. At the same time, the movement of the first anti-collision plate 6 or the second anti-collision plate 7 can drive the first push rod 12 or the second push rod 13 to move. The movement of the first push rod 12 or the second push rod 13 can cause the top plate 9 to rise by contacting the second trapezoidal plate 11 or the first trapezoidal plate 10. The rise of the top plate 9 can pull the ropes of multiple second springs 8, achieving the effect of absorbing the impact force for the second time. At the same time, the rise of the top plate 9 drives the damping rod 15 to rise. The rise of the damping rod 15 can achieve the effect of further absorbing the impact force by rubbing against the inner wall of the damping sleeve 14, effectively improving the anti-collision performance of the battery box body 2.
[0016] Specifically: the surface of the first anti-collision plate 6 is provided with a first vent hole 16, and a plurality of first vent holes 16 are provided; the surface of the second anti-collision plate 7 is provided with a second vent hole 17, and a plurality of second vent holes 17 are provided. By setting the first anti-collision plate 6 and the second anti-collision plate 7 and ensuring that the first anti-collision plate 6 and the second anti-collision plate 7 are not in contact with the battery box body 2, the effect of preventing the blockage of the heat dissipation holes on the surface of the battery box body 2 is achieved. Furthermore, by opening the first vent holes 16 and the second vent holes 17 on the surfaces of the first anti-collision plate 6 and the second anti-collision plate 7, air can circulate through the first vent holes 16 and the second vent holes 17 within the first anti-collision plate 6 and the second anti-collision plate 7, further reducing the impact on the heat dissipation of the battery box body 2.
[0017] Working Principle: This utility model is a collision protection structure for a port tractor battery box. By setting a first collision protection plate 6 and a second collision protection plate 7, when impacted, the first or second collision protection plate 6 can drive the sliding rod 5 to move into the sleeve 3. The movement of the sliding rod 5 compresses the first spring 4, achieving the effect of initial absorption of the impact force. Simultaneously, the movement of the first or second collision protection plate 6 or the second collision protection plate 7 can drive the first push rod 12 or the second push rod 13 to move. The movement of the first push rod 12 or the second push rod 13 can cause the top plate 9 to rise by contacting the second trapezoidal plate 11 or the first trapezoidal plate 10. The rise of the top plate 9 can pull the ropes of multiple second springs 8, achieving the effect of secondary absorption of the impact force. Simultaneously, the rise of the top plate 9... The dynamic damping rod 15 rises, and the rising damping rod 15 can further absorb the impact force by rubbing against the inner wall of the damping sleeve 14, effectively improving the anti-collision performance of the battery box body 2. Furthermore, by setting the first anti-collision plate 6 and the second anti-collision plate 7 and ensuring that the first anti-collision plate 6 and the second anti-collision plate 7 are not in contact with the battery box body 2, the heat dissipation holes on the surface of the battery box body 2 are prevented from being blocked. Moreover, by opening the first vent 16 and the second vent 17 on the surface of the first anti-collision plate 6 and the second vent 17, air can circulate through the first vent 16 and the second vent 17 within the first anti-collision plate 6 and the second anti-collision plate 7, further reducing the impact on the heat dissipation of the battery box body 2.
