Abstract
The utility model relates to a safety protective device, the prior trucks have the shortcomings of large wheel diameter, high chassis and no safeguard in the rear of the compartment, when a rear-end accident is occurred, the car driving at the back rushes under the tail of the car and causes fatal car crash due to the low head of the car. The utility model is characterized in that: the front end of a spare tire bracing arm is fixed at a longeron of the vehicle, a spare tire fixing plate at the rear end is fixed under the chassis at the tail of the vehicle with a tire chain and a stabilizing spring at the rear end by utilizing the lever principle of the connecting piece and the spare tire height adjustment block; the spare tire is fixed under the spare tire fixing plate by a bolt and is not more than 0.3 meters from the ground; the rubber part of the tire is extended out the rear of the compartment; the utility model is a tire anti-impact safety protection device which has the advantages of simple structure, convenient installation, good safety performance and low cost.
Description
When the utility model relates to a kind of rear-end collision accident, the protective device of protection safety of person vehicle, a kind of automobile tail that is installed in of definitely saying so, the return shock safety device that is assembled into by spare tyre.
Present load-carrying vehicle, truck, passenger vehicle, container car in usefulness, its vehicle wheel footpath is big, chassis, compartment height, chassis member rear end and compartment tail end have certain distance, spare tyre under the longeron and ground-surface height, and do not have any protective device with the nearly 0.8 meter space of the distance of compartment afterbody; And roadlice its take turns the footpath less, the chassis is low, headstock generally is lower than 0.5 meter apart from floor level.Two kinds of vehicles at running on expressway, because the car speed per hour is often per hour more than 100 kilometers, if with load-carrying vehicle generation rear-end collision, car will be rushed under the tailstock of car in front, when fierce the collision takes place in crash-resistant longeron afterbody of its headstock and automobile or compartment, even the luxury car of safety air bag is housed, also can cause the pernicious traffic accident of car crash.
Goal of the invention of the present utility model is: a kind of automobile tail that is installed in is provided, at ordinary times as changing of tire, and when rear-end collision takes place, can protects the spare tyre formula return shock safety device of safety of person vehicle effectively.
The objective of the invention is to realize: automobile tail spare tyre formula return shock safety device by the enforcement following technical proposals, comprise by spare tyre, the spare tyre adapter plate, the spare tyre hold-down arm, assemblies such as spare tyre stabilizing spring constitute, it is characterized in that: the preceding end connection of spare tyre hold-down arm is fixed on the longeron on chassis, its rear end is fixed on has the spare tyre bolt of rear end plate, on the spare tyre adapter plate of anti-slipping chain perforation and spare tyre stabilizing spring mount pad, this adapter plate is by the attaching parts of chassis member and the lever principle of spare tyre height adjustment card, and the anti-slipping chain and the spare tyre stabilizing spring of rear end, it is stabilized under the tail end chassis, spare tyre is then by the spare tyre bolt of rear end plate on the spare tyre adapter plate, and the hanger bar of anti-slipping chain end, be fixed in the spare tyre adapter plate below.Additional technical feature is: 1. spare tyre lift span and the anti-slipping chain on the compartment base, both can be used for lifting by crane spare tyre, and be convenient to fix with the spare tyre bolt of rear end plate, can help to adjust the height of spare tyre adapter plate again; 2. in the bottom of spare tyre adapter plate, by preventing spare tyre friction support frame, device prevents the spare tyre friction wheel, and the diameter of wheel requires the thickness greater than spare tyre, about 0.33 meter; 3. between the chassis member and spare tyre hold-down arm of the tailstock, spare tyre height adjustment card is installed, it is 0.3 meter apart from ground-surface minimum altitude that this card is adjusted spare tyre; 4. be stabilized in the spare tyre under the tailstock chassis, its rubber partly requires to stretch out the compartment tail end.Safety precaution principle of the present utility model is: by forming spare tyre stabilizing spring, spare tyre bolt of rear end plate on single-piece spare tyre hold-down arm, the spare tyre adapter plate, be contained in the spare tyre lift span on the compartment base with the spare tyre adapter plate, and have an anti-slipping chain of hanger bar, spare tyre is stabilized under the tailstock chassis, keep the height with 0.3 meter on ground, and the rubber of tire is partly stretched out the compartment tail end.Like this; when at the small passenger car of running on expressway, passenger vehicle, flush car and this automobile generation rear-end impact; because the height of front truck afterbody spare tyre approximates the height of back headstock bumper/spoiler; therefore the back car can not be rushed under the compartment of front truck; back car is to the afterbody spare tire of front truck bump the time; also produced the anti-force of spare tire, thereby protected the safety of person vehicle of back car effectively the back car.
Advantage of the present utility model is: spare tire had both been made change of wheels and had been used, the core component of double as protective device again, and outstanding feature such as it is simple to have an apparatus structure, installs, easy to maintenance, and the safety precaution performance is good, and is cheap for manufacturing cost, easy to utilize.
Mark among rear-end collision figure figure when the utility model has following accompanying drawing: Fig. 1 not have safety device for safeguard function scheme drawing Fig. 5 for automobile tail for apparatus structure birds-eye view Fig. 4 for apparatus structure installation left view Fig. 3 for apparatus structure installation front view Fig. 2: 1 is spare tyre, 2 is the spare tyre adapter plate, 3 is the spare tyre hold-down arm, 4 is the attaching parts of hold-down arm front end and chassis member, 5 is spare tyre height adjustment card, 6 is spare tyre stabilizing spring mount pad, 7 are anti-slipping chain perforation (the cross symbol in the hole is labeled as anti-slipping chain), 8 is the hanger bar of anti-slipping chain end, 9 is the spare tyre bolt of rear end plate, 10 is anti-slipping chain, 11 is the spare tyre stabilizing spring, 12 prevent spare tyre friction support frame for being contained in below the spare tyre adapter plate, 13 for preventing the spare tyre friction wheel, and 14 is the car chassis longeron, and 15 is the compartment base, 16 is automobile tail light, and 17 is the spare tyre lift span.
