An embodiment of the present invention provides a tire impact guide apparatus, as shown in fig. 1 to 7, including: a guide rail 10 and a shear block 20;
the first side of the guide rail 10 is fixedly arranged at a first position of the bottom of the front vehicle body of the vehicle, the first side of the shear block 20 is fixedly arranged at a second position of the bottom of the front vehicle body of the vehicle, the first position is the bottom of a fire wall of the vehicle, the second position is the lower hinge position of a connecting column of the vehicle, the fire wall is positioned at the bottom of the front vehicle body of the vehicle, the lower hinge of the connecting column is positioned at the bottom of the front vehicle body of the vehicle, and the connecting column is used for connecting the roof and the front cabin of the vehicle;
the second side surface of the guide rail 10 is fixedly connected with the first side surface of the shear block 20, and the second side surface of the guide rail 10 is perpendicular to the first side surface of the guide rail 10;
the third side surface of the guide rail 10 is in a curved surface shape, the protruding height of the third side surface of the guide rail 10 gradually decreases from one end far away from the shear block 20 to one end close to the shear block 20, the third side surface of the guide rail 10 is flush with the second side surface of the shear block 20 at one end close to the shear block 20, the third side surface of the guide rail 10 and the first side surface of the guide rail 10 are opposite side surfaces, and the second side surface of the shear block 20 is perpendicular to the first side surface of the shear block 20;
when the vehicle collides with the tire and the tire of the vehicle collides with the tire impact guide device under the action of external force, the guide rail 10 is used for guiding the tire and the rim of the vehicle to slide to the outer side of the vehicle body, and the shear block 20 is used for cutting off the connection structure between the rim and the knuckle so as to separate the vehicle and the tire.
In this embodiment, the above-mentioned tire impact guiding device includes the guide rail 10 and the shear block 20, wherein, the first side of the guide rail 10 is fixed and set up in the bottom of the vehicle firewall, the first side of the shear block 20 is fixed and set up in the lower hinge position of the vehicle connecting column, the guide rail 10 is in the curve that prevents the tire from sliding to the inside of the vehicle body, therefore through this structural arrangement, in the event that the vehicle collides with the above-mentioned tire impact guiding device in a biased way, and the tire of the vehicle impacts the above-mentioned tire impact guiding device under the action of external force, the tire of the vehicle can slide to the outside of the vehicle body along the guide rail 10, and the arrangement of the guide rail 10 can also prevent the tire of the vehicle from sliding to the inside of the vehicle body, when the tire slides to the position close to the connecting column, and in the event of striking the shear block 20, the connection structure between rim and knuckle can be cut off for the tire separates from the vehicle, thus reduce the impact of the tire to the vehicle, reduce the impact load of the driver in the vehicle, and further improve the safety when the vehicle impacts with the obstacle avoidance.
It should be noted that, the curvature of the third side of the guide rail 10 may be set by a person according to the size of the vehicle component and the actual working condition, which is not limited to the embodiment of the present invention.
It should be understood that the first side of the guide rail 10 may be fixed to the first position of the front underbody of the vehicle by welding, and likewise, the first side of the shear block 20 may be fixed to the second position of the front underbody of the vehicle by welding, and the connection stability between the tire impact guiding device and the vehicle may be improved by the fixation by welding, and in another alternative embodiment, the first side of the guide rail 10 may be fixed to the first position of the front underbody of the vehicle by screwing, and likewise, the first side of the shear block 20 may be fixed to the second position of the front underbody of the vehicle by screwing.
Similarly, the guide rail 10 and the cutout 20 may be fixed by welding.
It will be appreciated that the third side of the rail 10 is flush with the second side of the shear block 20 at the end adjacent the shear block 20, i.e. in the event of an offset collision of the vehicle, the tyre is moved by the rail 10 towards the side adjacent the shear block 20, the shear block 20 may sever the connection between the rim and the knuckle under the effect of the external force of the collision, such that the tyre is separated from the vehicle, if the third side of the rail 10 is not flush with the second side of the shear block 20 at the end adjacent the shear block 20, for example: the third side of the guide rail 10 is not coplanar with the second side of the shear block 20 at the end near the shear block 20, which may cause the tire to fail to reach the designated area, and thus the shear block 20 fails to cut off the connection structure between the rim and the knuckle, so that the tire cannot be separated from the vehicle.

Optionally, two opposite sides 14 of the third side of the rail 10 perpendicular to the first side of the shear block 20 are blade-shaped;
wherein, in the case that the vehicle collides with the tire of the vehicle in an offset manner and the tire of the vehicle collides with the tire impact guide by an external force, the opposite side edges 14 serve to reduce the contact surface of the tire with the guide rail so that the tire of the vehicle slides to the outside of the vehicle body.
In this embodiment, it can be understood that the third side of the guide rail 10 is formed in a blade shape parallel to the two opposite sides 14 of the tire sliding track, and by this structure, the friction force of the tire when contacting the guide rail 10 during sliding can be reduced, so that the tire of the vehicle can slide to the outside of the vehicle more easily in the event of an offset collision of the vehicle, and then is separated from the vehicle body after impacting the shear block 20, thereby improving the safety of the vehicle in the event of an offset collision.
The sharpness of the blade-like structure of the two opposite sides 14 requires the relevant personnel to evaluate, and the optimal blade shape is selected to reduce the friction force when the tire slides without damaging the tire.
