Abstract

A pneumatic tire bumper and safety vehicle having the pneumatic tire bumper. The pneumatic tire bumper comprises a bumper frame (5) and a pneumatic tire (13) provided therein with a cavity (12) and arranged on the bumper frame (5). The pneumatic tire bumper is arranged on the front and/or rear of a vehicle body. The pneumatic tire bumper is arranged on the vehicle body via telescoping arms at the centers of front and rear vehicle beams (23) and support beams (16) on two sides thereof. This utilizes the load-bearing and pressure-resistant performances of the pneumatic tire on the bumper to cushion and absorb forces of impact during a collision, protects vehicle frame structures in the front and rear of the vehicle body, increases safety protection for an occupant in the vehicle, reduces collision and injuries of a pedestrian outside the vehicle, and effectively solves the difficult problem of poor collision safety in various flat front vehicles due to the lack of an absorption-deformation area in the front of the vehicle.

Description

Inflatable tire bumper and safety car with the same

The present invention relates to a safety device and a safety vehicle for an automobile part and an automobile field, and more particularly to a pneumatic tire bumper and a safety vehicle with the pneumatic tire bumper. Background technique

Car safety is divided into active safety and passive safety, and passive safety is also called collision safety. Active safety involves driving maneuverability, while passive safety plays a major role in car safety. Vehicle passive safety technology is mainly divided into two categories: Body structure: cushioning and energy absorption; vehicle occupant protection: seat belt, airbag, safety steering system, safety seat, etc.; body structure in buffering, absorbing and reducing impact impact The force plays a major role, and the occupant protection in the car plays a secondary role in protection. The bumpers on the front and rear sides of the body are part of the body structure. The front bumper of the car has only a very limited cushioning and absorbing impact force, and its safety is limited to low-speed collision. With the rapid development of the expressway, the speed of the car has increased greatly, and the speed of collision of the car has also increased greatly. The impact of the existing bumper on the strong impact force is extremely likely to collapse and damage, which greatly threatens the safety of the occupants in the car. . Therefore, the existing car bumpers are no longer insured, and their safety effects and reliability have far exceeded the objective actual needs. New bumpers must be developed to meet modern driving safety. Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a pneumatic tire bumper which can withstand pressure against impact and cushion and absorb strong impact force during strong impact, and can greatly improve the safety performance of the front and rear side structures of the vehicle body.

Another object of the present invention is to provide a safety car with a pneumatic tire bumper that can withstand shock and cushioning, absorbs the violent impact force during strong impact, and makes the front and rear side structures of the vehicle body not damaged. Fully protect the safety of drivers and passengers inside the car.

The invention provides a pneumatic tire bumper, which is characterized in that it comprises a bar frame, a pneumatic tire with a cavity provided on the bar frame, a filling air cavity in the pneumatic tire cavity, and a pneumatic tire through the bumper The powerful pressure-resistance and non-deformation performance cushions and absorbs the impact force during collision, thus protecting the front and/or rear bumper from crushing damage.

The pneumatic tire bumper bar frame is an arc frame, and the outer surface of the bar frame is set to be concave inward The two ends of the bar frame are respectively provided with a spiral head, and the spiral head is provided with a vertical long through hole, and a fixed card seat matched with the pneumatic tire is fixed on the inner side of the screw head, above the bar frame, the bar frame is The upper support plate and the lower support plate are respectively arranged under the shape of the bar frame, and the upper support plate and the lower support plate are respectively provided with fork ends respectively, and the pneumatic tire is supported on the concave surface of the outer surface of the bar frame on.

The vertical through hole on the screw head of the bar is set as two long through holes.

The forks at the ends of the upper and lower supports of the bar are set as double forks.

The two ends of the pneumatic tire are respectively provided with a plug, and the plug is engaged with the fixed card seat on the screw head of the bar frame, and the plug is fixed to the spiral through the snap ring and the fixing nail outside the plug On the head, the pneumatic tire is fixed to the bar frame.

The present invention provides a safety vehicle with the pneumatic tire bumper, including a vehicle body, wherein the front and rear sides of the vehicle body are inflated through a telescopic arm in the middle of the vehicle beam and a bolster on both sides of the telescopic arm. a tire bumper, the inflatable tire bumper slightly protrudes from the front and rear sides of the vehicle body, the pneumatic tire bumper includes a bar frame, and a pneumatic tire with a cavity on the concave surface of the bar frame, by making full use of the pneumatic tire on the bumper The pressure-resistant and anti-deformation performance cushions and absorbs the impact force during collision, thereby protecting the frame structure on the front and rear sides of the vehicle body from crushing and damage.

The telescopic arm is a first link and a second link which are hinged into an X shape, and the front ends of the two links are respectively passed through the left and right first hinge axes and the left fixed on the bar frame. The right first seat is hinged, and the rear ends of the two links are hinged to the left and right second seats fixed on the cross member of the vehicle through the left and right second hinge shafts, and the middle portions of the two links pass through The three-hinge shaft is hinged to a third seat fixed in the middle of the vehicle beam, and the hinge points of the first link and the second link are connected to a central spring located on the third seat to constitute a telescopic frame.

One ends of the bolsters on both sides of the telescopic arm are fixed on the bases on both sides of the telescopic arm on the bar frame, and the other end of the bolster and the section of the bolster are respectively placed in the side rails of the two sides, so as to The bar frame is supported, and under the action of the telescopic arm, the bar frame is moved back and forth along the longitudinal beam of the car to realize the expansion and contraction of the bar frame.

The present invention has the following advantages and effects: Compared with the protection effect of the bumper structure on the front and rear sides of the modern automobile body, and the limited absorption energy, the present invention provides inflation on the front and rear sides of the automobile body through the above scheme. The tire bumper makes full use of the strong pressure-bearing anti-collision performance of the pneumatic tire on the bumper to cushion and absorb the impact force during the collision, so as to protect the structure of the front and rear of the frame from the impact force. The damage will be greatly improved, and the safety and protection effect on the safety of the occupants and passengers in the vehicle will be greatly improved, and the triple safety effect of anti-collision, car protection and car protection will be achieved. The invented front and rear gram tire bumpers can be passively retracted after being hit, so that the impact damage to pedestrians and objects outside the vehicle can be effectively reduced, and the safety of pedestrians and objects outside the vehicle can be improved. The invention is applicable to various existing types of vehicles, such as a car, an MPV, an SUV, a commercial vehicle, etc., in particular, can better solve the problem that the collision safety of various flat head cars is lacking due to the lack of energy absorption deformation zone of the front end, thereby greatly improving the flat head. The collision safety of passenger cars and commercial vehicles is actually a safety car with a high reliability body structure. BRIEF DESCRIPTION OF THE DRAWINGS
