Abstract
The utility model is a vehicle secondary buffer bumper comprising a main spring (8) mounted at the front end of the vehicle body (1), wherein a support rod (5) is fixedly mounted at the front end of the main spring; a plastic bumper body (6) is fixedly mounted at the front end of the support rod (5); and a plurality of buffer springs (7) in the front-and-back direction are mounted in the plastic bumper body (6). In case of collision on the front surface, the plastic bumper body internally with the spring plays a role in primary buffering; and the plastic bumper body and the support rod can press the main spring backwards as secondary buffering. The two buffering processes successfully prolong the duration of impact and absorb impact force.
Description
Technical field
The utility model relates to a kind of vehicle bumper.
Background technology
The automotive front end operated by rotary motion has bumper/spoiler, is used for alleviating, absorbing the impact when colliding.The loss that is subject in collision in order to reduce vehicle as far as possible, design engineer generally concentrate on energy above the intensity of strengthening vehicle frame front end position, make its distortion when being collided in allowed limits.The shortcoming of doing like this is: bumper is complicated, and manufacturing cost is high, and does not eventually break away from the rigid collision of vehicle.When especially having an accident, will be more serious to the infringement of collision thing.
The utility model content
Technical problem to be solved in the utility model is, a kind of vehicle secondary buffer bumper is provided, and can more effectively absorb impact when being subject to frontal impact, has better buffering effect, reduces the infringement to the collision thing.To overcome the defective of existing vehicle bumper.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that adopts:
The vehicle secondary buffer bumper, it is characterized in that: comprise be used to the main spring that is installed in the car body front end, front end at described main spring is installed with strut bar, and described strut bar front end is installed with plastics thick stick body, and the recoil spring of some front and back trend is installed in described plastics thick stick body.
Offer some slotted eyes on the sidewall of described strut bar, be installed with the lock-bit spring at the inwall of described slotted eye, the outer end of described lock-bit spring is installed with the tongue pin; Described strut bar outside cover has the draw-in groove cylinder, and the rear end of described draw-in groove cylinder is fixedly installed in the car body front end, is provided with several at the inwall of described draw-in groove cylinder and is used for the draw-in groove that cooperates with described tongue pin.
Good effect of the present utility model is:
When frontal impact occured, the plastics thick stick body that is built-in with spring played for the first time buffer action, and plastics thick stick body pushes main spring backward together with strut bar, and this is to cushion for the second time.Twice buffering course successfully increased the time length that impacts and absorbed impulsive force.In second time buffering course, the tongue pin on the strut bar backward moving blockage is connected in the draw-in groove on the draw-in groove cylinder inwall, thereby the position of restriction bumper/spoiler avoids bumper/spoiler to eject forward, has reduced the infringement to collision object.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprise be installed in car body 1 front end about two main springs 8, front end at described main spring 8 is installed with strut bar 5, and described strut bar 5 front ends are installed with plastics thick stick body 6, and the recoil spring 7 of some front and back trend is installed in described plastics thick stick body 6.Sidewall at described strut bar 5 offers some slotted eyes, is installed with lock-bit spring 4 at the inwall of described slotted eye, and the outer end of described lock-bit spring 4 is installed with tongue pin 3.Described tongue pin 3 is not in the situation that be subjected to external force for stretch out shape outside slotted eye.
Described strut bar 5 outsides covers has draw-in groove cylinder 2, the rear end of described draw-in groove cylinder 2 to be fixedly installed in car body 1 front end, is provided with several at the inwall of described draw-in groove cylinder 2 and is used for the draw-in groove that cooperates with described tongue pin 3.
When frontal impact occured, the plastics thick stick body 6 that is built-in with recoil spring 7 played for the first time buffer action, if impact is enough large, plastics thick stick body 6 pushes main spring 8 backward together with strut bar 5, and this is to cushion for the second time.In second time buffering course, the tongue pin 3 on the strut bar 5 backward moving blockage is connected in the draw-in groove on the draw-in groove cylinder inwall, thereby the position of restriction bumper/spoiler is avoided whole bumper/spoiler to eject forward, thereby reduced the injury to collision object.
