Abstract
The utility model discloses an air spring bumper, which comprises a bumper and an air spring structure. Wherein, the air spring structure is composed of a cylinder rod, a cylinder sleeve, a vent hole and a damping spring with a simple structure. A popularity of air spring can be arranged at the front and back end and other parts prone to undergo collision for vehicles, thus bringing great convenience. In case of accident and bumper collision, the cylinder rod is propelled into the cylinder sleeve to make the air in the cylinder sleeve discharged through the vent hole, release impact energy, effectively relieve collision seriousness and reduce injury by releasing impact energy through the damping spring.
Description
Technical field the utility model relates to a kind of vehicle bumper, especially has the vehicle bumper of air bellow structure.
The background technology vehicle is just popularized along with the progressively raising of people's life.But traffic accident is also in rising trend.How avoiding traffic accident, perhaps alleviate the collision degree as far as possible when having an accident, to reduce damage, is an important problem.
Chinese patent CN1204599 number disclosed " the forward and backward formula safety air bag shock absorber of putting of automobile " patent (application number: CN98115842.0), form by adapter plate and gascollecting cap cylinder, open valve, exhaust pump and pipeline etc. that safety air bag and safety air bag front end buffering outer cover and safety air bag rear side link; When the driver thinks that the vehicle driven inevitably or may take place to bump against with other vehicle the time, opens this device, it is extrapolated that gas makes safety air bag cushion outer cover; Bump against when taking place,, can reduce the impulsive force of vehicle when front and rear direction collides, passengers inside the car are played the safety guard-safeguard effect better, the damage rate of vehicle is reduced because the effect of safety air bag shock absorber is arranged.The weak point of this patent is: form complex structure by adapter plate and gascollecting cap cylinder, open valve, exhaust pump and pipeline etc. that safety air bag and safety air bag front end buffering outer cover and safety air bag rear side link; Safety air bag is too soft, and to alleviate degree limited to very stiff and demanding between the vehicle.
Chinese patent CN86205353 number disclosed " automobile safety device " patent (application number: CN86205353), comprise electric ignition loop, gunpowder firing device, guard net, gas wall, gas wall charge valve, gas cylinder and brake valve.Automobile in running at high speed, when running into emergency situation, driver's demand working electric ignition circuit switching; Light the gunpowder firing device; by the thrust that powder burning produced; the scalability guard net that will be positioned at car the place ahead struts; because the effect of Backlash; gas wall charge valve and brake valve be action simultaneously also, accomplishes not only to brake but also can protect car the place ahead pedestrian in time, avoids because the traffic accident that automobile inertial causes; device action speed is fast, and is easy to operate.The weak point of this patent is: can not be quick-fried with quick-fried system, because the thrust that the burning of gunpowder firing device is produced may injure driver or pedestrian; And the driver can not guarantee to grasp the emergency situation and the sense of propriety on the opportunity of igniting.
The purpose of this utility model is exactly that a kind of vehicle air spring bumper/spoiler simple in structure will be provided, and alleviates the collision degree when having an accident as far as possible, to reduce damage.
The utility model content in order to achieve the above object, the vehicle air spring bumper/spoiler that the utility model provides is except comprising parts such as insuring bar body, also comprise the air bellow structure: the air bellow structure is made up of piston rod, cylinder sleeve, air extractor vent, recoil spring, wherein, cylinder sleeve is fastened on the vehicle chassis; Insurance bar body and piston rod are for being fastenedly connected; Air extractor vent is positioned on the cylinder sleeve; Recoil spring connects piston rod head and cylinder sleeve bottom, plays shock absorbing and reset response.When the present invention used, piston rod, cylinder sleeve and air extractor vent were formed air bellow, added recoil spring and formed the multi-buffer structure; When vehicle had an accident, the insurance bar body was impacted, and the compressing piston rod moves in cylinder sleeve, thereby forced the air in the cylinder sleeve to discharge impact force by the air extractor vent discharge, simultaneously, also discharged impact force by the compression recoil spring.
For further making the utility model be convenient to use, cylinder sleeve be fastened on the vehicle chassis form for be threaded, rivet connects or weld; The form that insurance bar body and piston rod are fastenedly connected for be threaded, rivet is connected or weld.
The vehicle air spring bumper/spoiler that the utility model provides has a significant effect: except comprising parts such as insuring bar body, also comprises the air bellow structure, forms by piston rod, cylinder sleeve, air extractor vent, recoil spring, and simple in structure; The air bellow structure has a plurality of, can be placed in vehicle front, rear end or other position that easily bumps, and is easy to use; When having an accident, when vehicle has an accident, the insurance bar body is impacted, the compressing piston rod moves in cylinder sleeve, thereby force the air in the cylinder sleeve to discharge impact force, simultaneously, also discharge impact force by the compression recoil spring by the air extractor vent discharge, can effectively alleviate the collision degree, reduce damage.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing is represented square section of the present utility model scheme drawing.
Structure shown in the drawings comprises: cylinder sleeve (1), piston rod (2), insurance bar body (3), air extractor vent (4), recoil spring (5), vehicle chassis (6).
The vehicle air spring bumper/spoiler that specific embodiment the utility model provides is except comprising parts such as insuring bar body (3), also comprise the air bellow structure: the air bellow structure is made up of piston rod (2), cylinder sleeve (1), air extractor vent (4), recoil spring (5), wherein, cylinder sleeve (1) is fastened on the vehicle chassis (6); Insurance bar body (3) and piston rod (2) are for being fastenedly connected; Air extractor vent (4) is positioned on the cylinder sleeve (1); Recoil spring (5) connects piston rod (2) head and cylinder sleeve (1) bottom, plays shock absorbing and reset response.When the present invention used, piston rod (2), cylinder sleeve (1) and air extractor vent (4) were formed air bellow, added recoil spring (5) and formed the multi-buffer structure; When vehicle has an accident, insurance bar body (3) is impacted, and compressing piston rod (2) moves in cylinder sleeve (1), discharges impact force thereby force the interior air of cylinder sleeve (1) to be discharged by air extractor vent (4), simultaneously, also discharge impact force by compression recoil spring (5).
For further making the utility model be convenient to use, cylinder sleeve (1) be fastened on the vehicle chassis (6) form for be threaded, rivet connects or weld; The form that insurance bar body (3) is fastenedly connected with piston rod (2) for be threaded, rivet is connected or weld.
The utility model protection domain relates to all changes form recited above.
