Abstract
The utility model relates to a school bus rear wall anticollision power-absorbing buffer device which is characterized by being arranged between a rear bumper and a rear beam and fixed on end portions of the rear beam and a longitudinal beam, wherein the buffer device comprises a supporting frame in a framework structure shaped like a Chinese character 'ao' and a rectangular anticollision board which is transversely arranged and fixed on the supporting frame, the overall anticollision board is of a wavy structure, the left end and the right end of the anticollision board are fixed on a transverse structure on the front portion of the supporting frame, and a longitudinal structure on the rear portion of the supporting frame is fixed at two ends of the rear beam. The school bus rear wall anticollision power-absorbing buffer device has the advantages that the supporting frame is formed by the wavy anti-collision board and square tubes, the anti-collision board and the supporting frame, the supporting frame and the longitudinal beam, and the supporting frame and the rear beam are in fixed connection in a welded mode, so that the supporting frame plays a role of secondary buffer action by conducting force applied on the anti-collision board, that is, the supporting frame damages and disburdens a part of impact force conducted to the longitudinal beam, reduces deformative damage caused by collision force to the longitudinal beam and a car body, and improves the safety of the school bus.
Description
Technical field
The utility model relates to the vehicular spare parts field, especially a kind of school bus back wall anti-collision energy absorption shock absorber.
Background technology
The meaning of back buffer beam is exactly the device that vehicle bears impact for the first time, is exactly that a bit stressed whole body is stressed in that an important idea is arranged aspect the vehicle body passive security.The some positions that are exactly frankly speaking car body have been subject to bump, and iff allowing this position go holding capacity, the protection effect that reaches so can be very poor.If when certain a bit is subject to power, allow whole skeleton structure go holding capacity, then can reduce to greatest extent an intensity of force that point is suffered, particularly the rear anti-crash girder steel just plays effect clearly here, but only depend on the rigidity collision prevention girders very undesirable aspect energy-absorbing buffering, domestic passenger vehicle does not mostly have better Anticollision Measures, and wherein school bus is particularly paid attention to safety measure, and domestic school bus does not all have good rear portion anticollision device unfortunately.
The utility model content
The purpose of this utility model provides a kind of safer aspect the crashproof buffering energy-absorbing, reliable and easily school bus back wall anti-collision energy absorption shock absorber is installed.
In order to finish above-mentioned purpose, the technical solution adopted in the utility model is:
School bus back wall anti-collision energy absorption shock absorber, described shock absorber is arranged between rear bumper and the after cross member and is fixed on the end of after cross member and longeron, shock absorber comprises bracing frame and the horizontally set of concave shape framed structure and is fixed on rectangle Crashworthy plate on the bracing frame, Crashworthy plate integral body is wavy shaped configuration, the two ends, the left and right sides of Crashworthy plate are fixed on the transversary of bracing frame front portion, and the longitudinal construction at bracing frame rear portion is fixed on the two ends of after cross member.
Described bracing frame is fixedly formed by square tube.
The horizontal section of described Crashworthy plate is the wave structure of rectangle.
The fixed form of described Crashworthy plate and bracing frame, bracing frame and longeron, bracing frame and after cross member is welding.
The beneficial effects of the utility model are: the bracing frame that corrugated Crashworthy plate is set between rear bumper and after cross member, is comprised of square tube, the fixed form of Crashworthy plate and bracing frame, bracing frame and longeron, bracing frame and after cross member is welding, make bracing frame play the level 2 buffering effect of the stressed backward longeron conduction of Crashworthy plate---by the impulsive force of bracing frame self damage removal part to the longeron conduction, reduce as far as possible impact to the distortion infringement of longeron, vehicle body, improved the buffering energy-absorbing ability of school bus, the safety that has greatly improved school bus.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, rear bumper, 2, after cross member, 3, longeron, 4, bracing frame, 5, Crashworthy plate.
The specific embodiment
The utility model is school bus back wall anti-collision energy absorption shock absorber, the bracing frame that corrugated Crashworthy plate is set between rear bumper and after cross member, is formed by square tube, the fixed form of Crashworthy plate and bracing frame, bracing frame and longeron, bracing frame and after cross member is welding, make bracing frame play the level 2 buffering effect of the stressed backward longeron conduction of Crashworthy plate---by the impulsive force of bracing frame self damage removal part to the longeron conduction, reduce as far as possible impact to the distortion infringement of longeron, vehicle body, improved the buffering energy-absorbing ability of school bus, the safety that has greatly improved school bus.
Below in conjunction with accompanying drawing the utility model is described further.
Specific embodiment, as shown in Figure 1, school bus back wall anti-collision energy absorption shock absorber, shock absorber is arranged between rear bumper 1 and the after cross member 2 and is weldingly fixed on the end of after cross member 2 and longeron 3, shock absorber comprises bracing frame 4 and horizontally set and is weldingly fixed on rectangle Crashworthy plate 5 on the bracing frame 4, bracing frame 4 is fixed into the concave shape framed structure by square tubes soldering, Crashworthy plate 5 whole horizontal sections for wavy shaped configuration and Crashworthy plate 5 are the wave structure of rectangle, the two ends, the left and right sides of Crashworthy plate 5 are weldingly fixed on the transversary of bracing frame 4 front portions, the longitudinal construction at bracing frame 4 rear portions is weldingly fixed on the two ends of after cross member 2, Crashworthy plate 5 and bracing frame 4, bracing frame 4 and longeron 3, bracing frame 4 is welding with the fixed form of after cross member 2.The bracing frame that corrugated Crashworthy plate is set between rear bumper and after cross member, is formed by square tube, the fixed form of Crashworthy plate and bracing frame, bracing frame and longeron, bracing frame and after cross member is welding, make bracing frame play the level 2 buffering effect of the stressed backward longeron conduction of Crashworthy plate---by the impulsive force of bracing frame self damage removal part to the longeron conduction, reduce as far as possible impact to the distortion infringement of longeron, vehicle body, improved the buffering energy-absorbing ability of school bus, the safety that has greatly improved school bus.
