Problems solved by technology

[0003] A rear-end collision of a small vehicle is usually the contact between the front and the rear. Although it will cause damage to the car, the probability of personal injury is small, unless the speed is too fast
However, when a small vehicle collides with a large loaded vehicle, the front of the small vehicle enters the bottom of the large vehicle, the A-pillar of the small vehicle comes into contact with the interior of the large vehicle, the A-pillar breaks or bends, and the interior of the large vehicle invades. The cab of a small vehicle, causing the death of the driver
However, the energy-absorbing position of the front of the small vehicle cannot collide and absorb energy, resulting in the airbag of the small vehicle not being able to detonate normally, which further increases the death probability of the driver of the small vehicle

Embodiment 1

[0039] A vehicle bottom suspension device, comprising two connectors 1 installed on the outside of the longitudinal beam, the connectors 1 are in the shape of a "C"; screws 101 are screwed into the top of the connectors 1, and the screws 101 are screwed into Finally, against the longitudinal beam, the connecting piece 1 is fixed at this time, and a T-shaped steel plate 2 is installed at the bottom of the connecting piece 1, and a bolt 102 is fitted between the steel plate 2 and the connecting piece 1; The lower end of the steel plate 2 is provided with a casing 201, and the casing 201 is vertically arranged, and a steel rod 3 is inserted in the casing 201, and the transition fit between the steel rod 3 and the casing 201, so that The front end of the steel rod 3 is processed with an end portion 301, the diameter of the end portion 301 is larger than the diameter of the steel rod 3, and a head spring 4 is assembled on the steel rod 3, and the spring 4 acts on the Between the en...

Embodiment 2

[0041] A support plate 9 is assembled between the bottoms of the two connectors 1, the bolts 102 pass through the support plate 9, and the middle position of the support plate 9 is concaved to form a concave plate portion 901; The upper end flange of the horizontal plate 5 is connected with a base 10, and the upper end of the base 10 has a force plate 11; a passive brake plate 12 made of rubber is installed at the bottom of the concave plate part 901, and the passive brake plate 12 A first bolt 13 is fitted between the concave plate part 901 , and a plurality of brake pads 14 are arranged longitudinally and equidistantly on the bottom of the passive brake plate 12 . When the spare tire 7 is hit, the horizontal plate 5 Move backward, at this time, the force plate 11 moves to the rear side and acts on the brake pad 14. After the brake pad 14 in contact with it is deformed, the force plate 11 continues to contact the rear brake pad 14; The distance between the two brake pads 14 i...

Embodiment 3

[0043] A plurality of ribs 911 are welded between the support plate 9 and the concave portion 901; the design of the ribs 911 is mainly to increase the structural strength at the transition position between the support plate 9 and the concave portion 901.

Abstract

The invention discloses a vehicle bottom hanging device and a using method thereof. The vehicle bottom hanging device comprises two connecting pieces installed on the outer sides of a longitudinal beam, and each connecting piece is in a C shape; screws are screwed into the tops of the connecting pieces and abut against the longitudinal beam after being screwed into the connecting pieces, the connecting pieces are fixed at the moment, a T-shaped steel plate is installed at the bottom of each connecting piece, and bolts are arranged between the steel plates and the connecting pieces in a matchedmode; and a sleeve is arranged at the lower end of each steel plate. After the device is provided with a spare tire, the head of a small vehicle collides with the spare tire after entering the device, an air bag of the vehicle is detonated, meanwhile, the entering depth of the small vehicle is reduced, the spare tire is soft and deformable, and therefore vehicle damage can be reduced.

Description

technical field [0001] The invention relates to a vehicle bottom suspension device and a using method. Background technique [0002] Rear-end collision refers to the behavior that the front of the rear vehicle collides with the rear of the front vehicle when vehicles traveling in the same lane are following behind. It is mainly caused by the follow-up distance being less than the minimum safety distance and the slow response of the driver or the poor performance of the braking system. [0003] A rear-end collision of a small vehicle is usually the contact between the front and the rear. Although it will cause damage to the car, the probability of personal injury is small unless the speed of the vehicle is too fast. However, when a small vehicle collides with a large loaded vehicle, the front of the small vehicle enters the bottom of the large vehicle, the A-pillar of the small vehicle comes into contact with the interior of the large vehicle, the A-pillar breaks or bends, a...
