Abstract
The utility model discloses an automatic extending passenger car bumper. The automatic extending passenger car bumper is characterized by comprising a corrugated plate thin-wall beam, an electrically controlled hydraulic telescopic energy absorber, a corrugated pipe, a buffer material, a guide rail and a wind screen; the corrugated plate thin-wall beam is arranged on the forefront, the wind screen and the buffer materials are arranged behind the corrugated plate thin-wall beam, the corrugated pipe is connected with the electrically controlled hydraulic telescopic energy absorber by use of a rotating pin, and after collision, the electrically controlled hydraulic telescopic energy absorber is still capable of sliding backwards along the guide rail. The automatic extending passenger car bumper adopts three-level buffer based on corrugated pipe energy adsorption in combination with a circular thin-wall plate and a hydraulic mechanism, and the corrugated pipe energy adsorption, the circular thin-wall plate and the hydraulic mechanism are combined reasonably to achieve excellent buffering energy adsorption effect. The automatic extending passenger car bumper is arranged on the front part of a vehicle to achieve the effects of increasing an impacting distance and improving frontal impact response; the automatic extending passenger car bumper is simple and compact in structure, low in cost, high in reliability and convenient to control, and thus can be widely applied to the development of passenger cars of various model numbers and the security improvement of old car models.
Description
Technical field
The utility model relates to a kind of automotive front collision energy-absorbing device, relates in particular to a kind of auto-extending formula passenger vehicle bumper.
Background technology
At present, highway in China is built continuing to increase of dynamics, has greatly promoted the fast development of highway passenger transportation.Add up according to Department of Transportation: the whole year in 2010, highway transports passenger and reaches 306.3 hundred million person-times, account for 93.38%, 2011 year of various forms of transport passenger traffic total amount this than classifying 93.21% as, and ton-kilometerage volume also accounts for " half of the country " of total turnover volume.On vehicle forms, within 2010, large-scale passenger train recoverable amount is 24939,58191 of other type vehicles in use.In the critical role of highway passenger transportation in passenger transportation highlights day by day, traffic safety problem is following, becomes lasting, the fast-developing neck bottle of restriction highway passenger transportation.The passenger vehicle head-on crashs such as rear-end collision happen occasionally, and cause vehicle and personal damage, and the anterior buffering energy-absorbing poor effect of existing passenger vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of auto-extending formula passenger vehicle bumper, overcomes existing passenger vehicle front energy-absorbing space little, the short shortcoming of collision ranging coverage.
A kind of auto-extending formula passenger vehicle bumper, it is characterized in that: comprise corrugated sheet thin-walled beam, the flexible energy absorption device of electric-controlled hydraulic, bellows, padded coaming, guide rail, air baffle, corrugated sheet thin-walled beam is placed in forefront, air baffle and padded coaming below, bellows connects by the flexible energy absorption device of rotation pin and electric-controlled hydraulic, and after collision, the flexible energy absorption device of electric-controlled hydraulic can also slide backward along guide rail.
A kind of auto-extending formula passenger vehicle bumper, is characterized in that: corrugated sheet thin-walled beam is the weldment of corrugated sheet and thin-walled steel plate, corrugated sheet cross section is semicircle tubulose steel body.
A kind of auto-extending formula passenger vehicle bumper, it is characterized in that: this device is installed on passenger-carrying chassis, realized the flexible operating mode of this device by the flexible energy absorption device of electronic system control electric-controlled hydraulic, when reaching certain speed of a motor vehicle, the bellows of this device can be stretched out by passenger vehicle, form alert status, make passenger vehicle in the time of head-on crash, there is good cushion characteristic, reach the effect of best anti-central collision, lower than in a certain speed of a motor vehicle a period of time or when passenger vehicle stops automatically by its withdrawal.
The utility model adopts three grades of bufferings, take bellows energy-absorbing as basis, and in conjunction with Circular Thin plate, hydraulic gear, they is reasonably combined, thereby plays good buffering energy-absorbing effect.Compared with prior art, its advantage is: 1, can effectively solve passenger vehicle central collision time, and the problem of front energy-absorbing insufficient space; 2, can be by the energy of collision by bellows and hydraulic efficiency pressure system consumption; 3, have simple in structure, easy to use, easy-maintaining and replacing, the feature such as room for improvement is large, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. guide rail, the 2. flexible energy absorption device of electric-controlled hydraulic, 3. rotation pin, 4. bellows, 5. padded coaming, 6. corrugated sheet thin-walled beam, 7. air baffle.
The specific embodiment
Now be described with reference to the accompanying drawings the embodiment of the utility model structure:
A kind of auto-extending formula passenger vehicle bumper, it is characterized in that: comprise corrugated sheet thin-walled beam 6, the flexible energy absorption device 2 of electric-controlled hydraulic, bellows 4, padded coaming 5, guide rail 1, air baffle 7, corrugated sheet thin-walled beam 6 is placed in forefront, air baffle 7 and padded coaming 5 below, bellows 4 connects by the flexible energy absorption device 2 of rotation pin 3 and electric-controlled hydraulic, and after collision, the flexible energy absorption device 2 of electric-controlled hydraulic can also slide backward along guide rail 1.Corrugated sheet thin-walled beam 6 is the weldment of corrugated sheet and thin-walled steel plate, and corrugated sheet cross section is semicircle tubulose steel body.The utility model is installed on passenger-carrying chassis, realize flexible operating mode of the present utility model by the flexible energy absorption device 2 of electronic system control electric-controlled hydraulic, in the time that reaching certain speed of a motor vehicle, bellows 4 of the present utility model can be stretched out by passenger vehicle, form alert status, make passenger vehicle in the time of head-on crash, there is good cushion characteristic, reach the effect of best anti-central collision, lower than in a certain speed of a motor vehicle a period of time or when passenger vehicle stops automatically by its withdrawal.Operative body of the present utility model is bellows 4 energy absorption devices.In the time of passenger vehicle and other vehicles or object generation head-on crash, first contacted with corrugated sheet thin-walled beam 6 by collision body, corrugated sheet thin-walled beam 6 crimp under the effect of impact (I level buffering), energy is delivered to bellows 4 then, cause bellows 4 compressive deformations and absorb most energy (II level buffering), residue residual amount of energy promotes rear slider and moves backward along guide rail 1, and the flexible energy absorption device 2 of last electric-controlled hydraulic resists and absorbs last residual amount of energy (III level buffering).In addition, also have the layout of some bolt parts on the utility model assembly, they also can absorb part energy at stress deformation or in fractureing, and therefore, the utility model releases energy for buffering and the bounce-back potential energy that reduces car body has good effect.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes identical, should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
