Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body bottom plates, in particular to a high-strength anti-collision vehicle body bottom plate with a buffer mechanism. Background Art

[0002] The frame is used as the load-bearing matrix of the vehicle, and is used by trucks, medium-sized and below passenger cars, and mid-to-high-end and high-end cars. It supports all the spring-mounted mass-related parts such as the engine, clutch, transmission, steering gear, non-load-bearing body and cargo box. For this reason, the frame should have sufficient bending rigidity so that the relative positions of the related mechanisms on it remain unchanged during the driving process of the vehicle and the deformation of the body is minimized. However, there are still certain problems when using the existing body floor:

[0003] For example, a body floor of a vehicle frame with announcement number CN203864795U has a technical solution as follows: including a transmission shaft channel, a floor, a door sill and a frame, the transmission shaft channel is connected to the floor, the floor is connected to the frame, the transmission shaft channel is placed at the front end of the floor, the door sill is placed at the rear end of the frame, and the frame includes a front end, a middle part and a rear end. The body floor of this frame has a simple structure, allowing the buffer arm to have a certain elastic deformation, which can absorb the impact from uneven roads and reduce the noise inside the car. The widening of the middle part of the frame is beneficial to improving the lateral stability of the car and shortening the overhang length of the device on the outer side of the frame longitudinal beam. However, when the existing body floor is hit by external force, it cannot buffer the body frame from multiple angles, so that excessive impact will cause damage to the body floor and affect the safety of the people in the car.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In response to the above problems, an innovative design was carried out based on the original body floor. Utility Model Content

[0015] Preferably, slide grooves are provided on the left and right sides of the movable block, and buffer blocks are horizontally installed inside the slide grooves.

[0016] With the above technical solution, when the first spring is squeezed and the moving block drives the buffer block to touch the first support plate and the second support plate, the buffer block will slide in the left and right directions, thereby providing a buffer force for the impact.

[0017] Preferably, the front and rear sides of the buffer block are provided with limiting grooves, and the limiting grooves are in an inverted "V" shape, and limiting columns are provided inside the limiting grooves.

[0018] With the above technical solution, when the buffer block collides with the first support plate and the second support plate, the limiting column moves up and down according to the shape of the limiting groove, converting the horizontal force into the vertical force.

When the convex part of the second protective plate 2 is hit by an external force, the horizontal parts on the left and right sides share a part of the force, and then the impact is buffered by the second elastic sheet 4, which plays a certain anti-collision role for the side impact of the vehicle body.

When the moving block 10 drives the buffer block 13 to touch the first support plate 5 and the second support plate 6, the buffer block 13 will slide in the left and right directions, thereby providing a buffer force for the impact. When the buffer block 13 collides with the first support plate 5 and the second support plate 6, the limiting column 15 moves up and down according to the shape of the limiting groove 14, converting the horizontal force into the vertical force, driving the support rod 16 and the extrusion block 17 to move downward, and the bottom of the extrusion block 17 can be supported by an elastic support, and the second spring 18 can drive the support rod 16 to reset, using elastic potential energy to buffer the vertical force, thereby ensuring the impact buffering effect on the vehicle body or the rear end.
