The outer side of the first buffer rod 603 is located between the contact plate 604 and the buffer plate 602 and is sleeved with a first elastic member 605. When the support B-pillar 4 is hit The anti-collision shell 601 is subjected to impact force, and the anti-collision shell 601 performs a buffering treatment on the impact force. Then, the contact plate 604 in the impacted area moves toward the position of supporting the B-pillar 4, and the elastic member is squeezed to shorten. At the same time, the impact force is buffered for the second time through the first buffer rod 603, and the double buffering treatment is performed to reduce the impact on the vehicle.

When the supporting C-pillar 5 is hit, the outer baffle 702 is impacted and the anti-seismic effect of the second anti-collision component 7 is improved through the polyurethane foam plastic pad. The cross frame 705 and the second buffer rod 706 are helpful to disperse the impact force and improve the impact resistance of the automobile frame.

[0020] Specifically, the first buffer rod 603 includes a support cylinder 6031, in which a support rod 6032 is arranged, and a sealing cover 6033 is arranged at one end of the support cylinder 6031 inserted into the support rod 6032, and a piston 6034 is arranged at one end of the support cylinder 6031 inserted into the support rod 6032, and the inner cavity of the support cylinder 6031 is located on both sides of the piston 6034 and is respectively set as a first hydraulic cavity 6035 and a second hydraulic cavity 6036, and a second elastic member 6037 is arranged between the inner side wall of the inner cavity of the support cylinder 6031 on the side away from the sealing cover 6033 and the piston 6034. When one end of the support rod 6032 is impacted, the support rod 6032 pushes the piston 6034 to move between the first hydraulic cavity 6035 and the second hydraulic cavity 6036, and the piston 6034 is supported by the second elastic member 6037. When the impact force is weakened, the squeezed second elastic member 6037 undergoes elastic deformation, so that the force on the support rod 6032 is balanced.

[0021] Specifically, the first hydraulic chamber 6035 and the second hydraulic chamber 6036 are connected, and hydraulic oil is stored in the first hydraulic chamber 6035 and the second hydraulic chamber 6036. As the piston 6034 moves, the hydraulic oil in the first hydraulic chamber 6035 and the second hydraulic chamber 6036 is forced to flow, thereby reducing the impact force and effectively maintaining the balance and stability of the entire frame.

[0022] Specifically, the first buffer rod 603 and the second buffer rod 706 have the same structure.

[0023] Specifically, the anti-collision shell 601 includes a first anti-collision layer 6011 and a second anti-collision layer 6012, the first anti-collision layer 6011 is arranged on the outside of the second anti-collision layer 6012, and an energy absorption plate is arranged between the first anti-collision layer 6011 and the second anti-collision layer 6012, the energy absorption plate is arranged in an M shape, and the M-shaped energy absorption plate is interwoven with the first anti-collision layer 6011 and the second anti-collision layer 6012 to form a triangle to improve the strength of the second anti-collision component 7, prevent the supporting B-pillar 4 from deformation, and ensure the survival space of the people in the car.

[0024] Specifically, the contact plate 604 fits with the outer side wall of the support B-pillar 4 , thereby increasing the contact area between the contact plate 604 and the outer side wall of the support B-pillar 4 and dispersing the impact when subjected to force.

[0025] Specifically, the filling cavity 703 is filled with a polyurethane foam pad, which is beneficial to improving the anti-vibration effect of the second anti-collision component 7, has a simple structure, and is easy to replace.

[0026] Working principle: When the present invention is used, if the vehicle is accidentally hit during driving, when the supporting B-pillar 4 is hit, the anti-collision shell 601 is subjected to impact force, and the anti-collision shell 601 performs a buffering treatment on the impact force, and then the contact plate 604 in the impacted area moves toward the position of the supporting B-pillar 4, the elastic member is squeezed to shorten, and at the same time, the impact force is buffered for a second time through the first buffer rod 603. The double buffering treatment can reduce the impact on the vehicle, and at the same time, the contact area with the outer wall of the supporting B-pillar 4 is increased by the contact plate 604, so as to disperse the impact when the force is applied, and an energy-absorbing plate is arranged between the first anti-collision layer 6011 and the second anti-collision layer 6012. The M-shaped energy-absorbing plate is interwoven with the first anti-collision layer 6011 and the second anti-collision layer 6012 to form a triangle to increase the strength of the second anti-collision component 7, prevent the supporting B-pillar 4 from deforming, and ensure the safety of the people in the vehicle. There is storage space. When the supporting C-pillar 5 is hit, the outer baffle 702 improves the anti-seismic effect of the second anti-collision component 7 through the polyurethane foam plastic pad after the impact. The cross frame 705 and the second buffer rod 706 are conducive to dispersing the impact force and improving the impact resistance of the automobile frame. When one end of the support rod 6032 is hit, the support rod 6032 pushes the piston 6034 to move between the first hydraulic chamber 6035 and the second hydraulic chamber 6036, and the piston 6034 is supported by the second elastic member 6037. As the piston 6034 moves, the hydraulic oil in the first hydraulic chamber 6035 and the second hydraulic chamber 6036 is forced to flow, thereby reducing the impact force and effectively maintaining the balance and stability of the entire frame. When the impact force is weakened, the squeezed second elastic member 6037 undergoes elastic deformation, so that the support rod 6032 is subjected to balanced force.
