[0002] The front panel assembly is an important component of the cab. It mainly ensures the torsional rigidity of the vehicle body, improves collision safety, and controls the rearward displacement of the cab front panel after a collision. The structural design of the front panel assembly should not only meet the functional requirements of accessory installation, but also improve processability so that it has good welding performance on the production line. The front panel should have sufficient rigidity and strength to ensure the safety of the occupants.

[0003] However, the existing front panel body is produced by block processing and reassembly, which results in a loss of impact resistance of the front panel assembly. After the car front panel encounters a collision, it is very easy to deform and squeeze the space inside the car, causing certain safety hazards. At the same time, the air flow performance is low, resulting in poor heat insulation effect of the front panel.

[0004] Therefore, it is particularly important to design an impact-resistant front panel assembly to solve the above-mentioned defects. Utility Model Content

[0022] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figures 1-4 , the utility model provides a technical solution:

[0025] The anti-collision front panel assembly includes a front panel body 1, a buffer cavity 2 is opened at the top of the front panel body 1, a buffer plate 3 is movably installed inside the buffer cavity 2, a reinforcing plate 4 is fixedly connected to the middle of the inner side of the front panel body 1, a deformation cavity 5 is formed on the inner side of the reinforcing plate 4, a pressure plate 6 is fixedly connected to the top of the deformation cavity 5, a buffer mechanism 7 is fixedly installed between the pressure plate 6 and the front panel body 1, and a guide plate 8 is fixedly connected to the inner side of the front panel body 1 and on the left and right sides of the reinforcing plate 4.

[0026] First, the upper and lower ends of the buffer cavity 2 are fixedly connected with the connecting box 201, and the upper and lower ends of the buffer plate 3 are slidably connected to the inside of the connecting box 201 through the connecting edge 301. When the front panel body 1 is hit, the connecting edges 301 at the upper and lower ends of the buffer plate 3 slide on the inner side of the connecting box 201, so that the arc-shaped buffer plate 3 on the inner side of the buffer cavity 2 absorbs energy through deformation, thereby improving the impact resistance of the front panel body 1.

[0027] Furthermore, a plurality of first springs 302 are movably mounted on one end of the connecting edge 301 located inside the connecting box 201, and the plurality of first springs 302 are evenly spaced between the connecting edge 301 and the connecting box 201. When the connecting edge 301 slides inside the connecting box 201, it squeezes the plurality of evenly distributed first springs 302, and utilizes the contraction deformation of the plurality of first springs 302 to further absorb the impact force, thereby further improving the anti-impact effect of the front panel main body 1.

[0028] Then, the left and right ends of the pressure plate 6 are fixedly connected to the inner side of the reinforcing plate 4, and multiple groups of connecting ribs 601 are fixedly connected between the pressure plate 6 and the reinforcing plate 4. The reinforcing plate 4 can directly improve the structural strength of the front panel body 1. When the front panel body 1 is subjected to a large impact, the top of the reinforcing plate 4 is located at the bend of the front panel body 1 and will first absorb energy through deformation. The buffer mechanism 7 can absorb most of the potential energy to reduce the impact of the impact. As the impact force increases, the pressure plate 6 and the multiple groups of connecting ribs 601 can absorb energy through deformation, thereby greatly improving the anti-impact effect of the front panel body 1. At the same time, the inner side of the buffer cavity 2 can increase air circulation to help take away heat, thereby reducing the temperature of the front panel body 1 and further improving the heat insulation effect of the front panel body 1.

[0029] Furthermore, the buffer mechanism 7 includes a slide rod 701 fixedly connected to the inner side of the reinforcing plate 4, and the left and right ends of the slide rod 701 are slidably connected to the slide sleeve 702. The outer side of the slide rod 701 and the side opposite to the two sets of slide sleeves 702 are both provided with a second spring 703. The outer sides of the two sets of slide sleeves 702 are rotatably connected to the transmission rod 704. A connector 705 is fixedly connected between the two sets of transmission rods 704. The end of the connector 705 close to the pressure plate 6 is fixedly connected to the extrusion plate 706. When the main body of the current enclosure is After a large impact, the top end of the reinforcing plate 4 located at the bend of the front panel body 1 will first absorb energy by deformation. When the top end of the reinforcing plate 4 is deformed, it will directly act on the pressure plate 6 to compress the space between the pressure plate 6, so that the pressure plate 6 will push the extrusion plate 706, and the sliding sleeve 702 will slide on the outside of the sliding rod 701 under the transmission of the transmission rod 704. Under the compression deformation of the second spring 703, the impact force is further buffered, thereby greatly improving the impact resistance of the front panel body 1.

[0030] Secondly, a connecting sleeve 707 is fixedly connected to the middle of the sliding rod 701, and a buffer pad 708 is fixedly connected to the side of the connecting sleeve 707 close to the connecting head 705. When the space between the reinforcing plate 4 and the pressure plate 6 is compressed, the connecting head 705 will gradually approach the buffer pad 708, and the buffer pad 708 will press against the connecting head 705 to further buffer the impact force, and at the same time protect the sliding rod 701, so that the sliding rod 701 will not bend and be damaged immediately, and the sliding sleeve 702 will slide on its outer side as much as possible to push the second spring 703 to absorb energy, thereby further improving the impact resistance of the front panel body 1.

[0031] Finally, multiple groups of guide tubes 801 are fixedly connected to the outside of the guide plate 8, and the multiple groups of guide tubes 801 are evenly spaced outside the guide plate 8. The multiple groups of guide tubes 801 outside the guide plate 8 can increase air circulation and help take away heat, thereby reducing the temperature of the front panel body 1 and further improving the heat insulation effect of the front panel body 1. At the same time, the guide plate 8 and the guide tubes 801 can be used to strengthen the bending part of the front panel body 1, further improving the impact resistance of the front panel body 1.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the front panel body 1 is hit, the connecting edges 301 at the upper and lower ends of the buffer plate 3 slide on the inner side of the connecting box 201, so that the arc-shaped buffer plate 3 on the inner side of the buffer cavity 2 absorbs energy through deformation. When the connecting edges 301 slide inside the connecting box 201, they squeeze multiple groups of evenly distributed first springs 302, and the multiple groups of first springs 302 shrink and deform to further absorb the impact force. When the front panel body 1 is hit hard, the top end of the reinforcing plate 4 located at the bend of the front panel body 1 will first absorb energy through deformation, and the buffer mechanism 7 can absorb most of the potential. It can reduce the impact of the collision, and as the impact force increases, the pressure plate 6 and the multiple groups of connecting ribs 601 can absorb energy through deformation. The guide plate 8 and the guide tube 801 can be used to strengthen the bending part of the front panel body 1, further improving the anti-collision effect of the front panel body 1. At the same time, the multiple groups of guide tubes 801 on the inner side of the buffer cavity 2 and the outer side of the guide plate 8 can increase air circulation and help take away heat, thereby reducing the temperature of the front panel body 1. The entire operation process is simple and convenient. Compared with the existing front panel assembly, the utility model can improve the anti-collision effect and heat insulation effect of the front panel assembly through design.
