Abstract
The utility model relates to a buffer for vehicle collision, which is composed of a safety cross bar, a guide rod, a front stage buffering spring group, a guide rod barrel, a rear stage buffering spring group and locking mechanism for impact force absorption. The guide rod barrel is fixedly arranged on a vehicle girder; the guide rod provided with step faces is sheathed in the guide rod barrel, and is hinged with the safety cross bar; the front and the rear stage buffering spring groups are respectively sheathed on the guide rod; the locking mechanism is composed of a latch pin with an inclined plane, a compression spring and the skewed teeth of the guide rod. Because of the adoption of the front and the rear stage buffering spring groups which work orderly, the utility model has good buffering effect which is superior to that of the existing similar device, avoids the rebound phenomenon because of the arrangement of the locking mechanism, and increases the safety performance because of the additional arrangement of an automatic brake mechanism.
Description
The utility model relates to a kind of automobile head-on collision shock absorber.
Notification number is that the Chinese utility model patent of CN2178661Y has provided a kind of automobile head-on collision shock absorber, mainly hold to hit plate and be arranged on and hold the compression spring that hits between plate and the mount pad and constitute by the mount pad that is connected with crossbeam, combined type, can prevent the accident and the loss that cause because of car collision, and simple in structure, make easily, but what this utility model adopted is the single-stage compression spring buffer, so crashproof effect is limited, and does not absorb the member that impacts, easily produce rebound phenomena.
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of good buffer effect is provided and the automobile head-on collision shock absorber of rebound phenomena can not take place.
The purpose of this utility model is achieved through the following technical solutions.This automobile head-on collision shock absorber is the left-right symmetric structure, by bumper transverse bar, guide rod, prime recoil spring group, the guide rod tube, the lockout mechanism of back level recoil spring group and absorption impulsive force is formed, the guide rod tube is fixedly mounted on the automotive frame, guide rod one end is hinged on the bumper transverse bar, the other end is provided with step surface and is inserted in the guide rod tube, its termination is stretched out guide rod tube bottom surface and is provided with tightening nut, prime recoil spring group is enclosed within on the guide rod between bumper transverse bar and guide rod tube end face, back level recoil spring is mounted on and is enclosed within on the guide rod step surface in the guide rod tube, lockout mechanism is by band inclined-plane tongue pin, helical teeth on stage clip and the guide rod is formed, tongue pin and stage clip are fixedly mounted on the automotive frame, in the helical teeth on the tongue pin insertion guide rod.
For further realizing the purpose of this utility model, this automobile head-on collision shock absorber also is provided with automatic brake mechanism, form by dowel bar, lever and brake lever, lever is hinged on the crossbeam, and with hinged always be fulcrum, its two ends link to each other with dowel bar and brake lever respectively, and the other end of dowel bar is hinged on the bumper transverse bar, and the other end of brake lever then with in the automobile is established brake gear and joined.
The automobile head-on collision shock absorber that the utility model provides, because of having adopted forward and backward two-stage recoil spring group, each spring is worked successively, make buffering effect better, impulsive force when the setting of lockout mechanism makes it can absorb head-on collision, prevent rebound phenomena, the setting of automatic brake mechanism has improved its safety performance more.
Figure 1 shows that automobile head-on collision shock absorber integral structure scheme drawing.
Fig. 2 is a recoil spring group scheme drawing.
Provide specific embodiment of the present utility model below in conjunction with Figure of description, as shown in Figure 1.This automobile head-on collision shock absorber is the left-right symmetric structure, Fig. 1 is a left side constructional drawing, by bumper transverse bar (1), guide rod (2), prime recoil spring group (3), guide rod tube (12), the lockout mechanism of back level recoil spring group (13) and absorption impulsive force is formed, guide rod tube (12) is fixedly mounted on the automotive frame (7) by connecting element (10), guide rod (2) one ends are hinged on the bumper transverse bar (1), the other end is provided with step surface and is inserted in the guide rod tube (12), its termination is stretched out guide rod tube (12) bottom surface and is provided with tightening nut (11), prime recoil spring group (3) is enclosed within on the guide rod (2), be positioned between bumper transverse bar (1) and guide rod tube (12) end face, as shown in Figure 2, prime recoil spring group (3) is by three stage clips (3-1) that length is different, (3-2) and (3-3) form, when taking place, the automobile head-on collision is compressed buffering successively, back level recoil spring group (13) is located at and is enclosed within the guide rod tube (12) on guide rod (2) step surface, this spring assembly also is made up of three different stage clips of length, but its longest one each stage clip that is shorter in length than prime spring assembly (3), lockout mechanism is by band inclined-plane tongue pin (5), helical teeth (4) on stage clip (6) and the guide rod (2) is formed, tongue pin (5) and stage clip (6) are fixedly mounted on the automotive frame (7), in the helical teeth (4) on tongue pin (5) the insertion guide rod (2), automatic brake mechanism is by dowel bar (14), lever (8) and brake lever (9) are formed, lever (8) is hinged on the automotive frame (7), and be fulcrum with the hinge-point, its two ends link to each other with dowel bar (14) and brake lever (9) respectively, the other end of dowel bar is hinged on the bumper transverse bar (1), and the other end of brake lever (9) then with in the automobile is established brake gear and joined.The utility model principle of work is as follows: when car collision, insurance cross bar (1) forces guide rod (2) to be pressed in the guide rod tube (12), each stage clip of prime recoil spring group (3) is compressed buffering successively, because the effect of lockout mechanism tongue pin (5) and helical teeth (4), make guide rod (2) can only be pressed into and can't oppositely eject, thereby absorbed the impulsive force that the automobile head-on collision produces, avoided the rebound phenomena after the buffering, after prime recoil spring group (3) was compressed to a certain degree, back each stage clip of level spring assembly (13) entered mode of operation again successively and plays buffer action.Automatic brake mechanism drives lever (8) by dowel bar (14) and rotates, thereby drives brake lever (9) pulling brake.
