Abstract
The utility model relates to a collision resistant automobile bumper which is characterized in that a rubber front plate is arranged in front of a bearing frame, a spring is assembled between the bearing frame and the rubber front plate, the bearing frame is penetrated with a plurality of spring limiting threaded rods provided with slope-shaped teeth, the front end of each spring limiting threaded rod is connected with a limiting plate, and the bearing frame is assembled with a stop member with displacement. The stop end of the stop member contacts the slope-shaped teeth of the spring limiting threaded rods. The other end of the stop member is connected with a driving device. When the automobile is collided, the utility model can damp and weaken the external force, reduce the damage or abandonment of automotive bodies, which is caused by traffic accidents, and raise drivers and passengers' running safety.
Description
The utility model belongs to a kind of Federal bumper, particularly a kind of crash-worthiness Federal bumper.
Bumper/spoiler all is equipped with in the front end or the rear end of various types of automobiles at present, its material adopts relatively thinner steel plate or plastics to make, and is a kind of decorative fitting actually, when seeing the auto against accident often, bumper/spoiler does not have safety effect at all, causes automobile body damage in various degree.
The purpose of this utility model provides a kind of crash-worthiness Federal bumper, when automobile is collided, can cushion and weaken external force, reduces the car body damage that causes owing to traffic accident or scraps raising driver and conductor's travel safety.
The purpose of this utility model is achieved in that it comprises heavy frame, and its technical scheme main points are: the place ahead of heavy frame is provided with the rubber header board, assembles spring between heavy frame and rubber header board; Install the spacing screw rod of several springs with slope tooth on heavy frame, the spacing screw front end of spring connects positioning plate, the retainer of assembling energy displacement on heavy frame, and the slope tooth of the spacing screw rod of retainer stop end connect spring, the other end connects actuating device.
The affixed stop collar in end of the spacing screw rod of above-mentioned spring.
The inner affixed heavy frame of above-mentioned spring.
Principle of work: during installation, heavy frame of the present utility model and car chassis front and rear portions be fixed together to get final product.When automobile was collided, the rubber header board was stressed and pass to the positioning plate of the spacing screw front end of spring, and the positioning plate compression spring weakens and cushioned impact force, and automobile body can not be damaged.The positioning plate compression spring retraction of collision rear spring spacing screw rod, because the unidirectional stop of retainer, the spacing screw rod of spring is fixed on the certain position can not resilience, has avoided because the destruction that bounce-back causes car body.When needs restore to the original state, handle actuating device and make the retainer cross travel, stop end breaks away from the slope tooth of the spacing screw rod of spring, the spacing screw rod of spring loses the limiting force to spring, spring recovers ortho states, positioning plate also returns to the home position, thereby will be by collision and the rubber header board jack-up under the localized indentation is restored.Enter a next mode of operation for the treatment of.
The utility model has the advantages that: when automobile is subjected to the external force collision, can cushion and weaken external force, the car body that minimizing causes owing to traffic accident damages or scraps, can make common collision accident reduce 80%, pernicious collision accident reduces 60%, improved automobile and driver and conductor's safety, and simple in structure, easy for installation.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is a kind of mounting structure scheme drawing of retainer.
Fig. 3 is a retainer similar alternative arrangements scheme drawing.
See Fig. 1,2, embodiment 1 concrete structure is as follows: on the spacing screw rod 6 of spring slope tooth is arranged, its front end welded limiting plate 4, pocketed springs 3 on the screw rod, spring 3 adopts the column type spring, can also adopt the waist drum type spring of two major diameter, middle minor diameter, and compression degree is bigger.The spacing screw rod 6 of spring passes freely through the heavy frame 5 of steel plate materials; Rubber header board 2 integral body are walked around the side from the front, in spring, the spacing screw rod of spring etc. is coated on, become external packing and be fixedly connected on heavy frame 5, positioning plate 4 had both played the effect that is subjected to external force compression spring 3, played the effect of support rubber header board 2 behind the spring reset again.Retainer 9 is slidingly mounted on the heavy frame 5 of the spacing screw rod of spring 6 both sides, and retainer 9 is Metal Flake, and its stop end perk peaks in the slope tooth groove of the spacing screw rod of spring, and the spring after the compression can not be rebounded.Chute 10 is arranged on the heavy frame 5, and retainer is slidingly mounted in the chute.See Fig. 3, also can adopt following mounting structure: have 18, two screws 17 of osed top long sliding hole on the retainer 9 and pass long sliding hole, be installed on the heavy frame 5, locking plate 9 slides on screw.Retainer 9 is hinged with the drive spindle 11 of actuating device, and drive spindle 11 is hinged on the heavy frame 5 by fulcrum 12, and the other end of drive spindle 11 and connecting rod 14 are hinged, the lever 15 of rod hinge connection band plate handle 16; Connecting rod 14 connects retracing spring 13.At the fastening suit rubber of the inner end stop collar 7 of the spacing screw rod 6 of spring, too much slip over heavy frame 5 to prevent the spacing screw rod 6 of spring.The rubber stop collar can also be set, but the inner of each spring must be welded on the heavy frame 5.Be positioned at heavy frame 5 both sides turn of bilges, the spacing screw rod of spring is not set, and adopt slide bar 1, therefore also save retainer.
Claims (3)
1, a kind of crash-worthiness Federal bumper, it comprises heavy frame, it is characterized in that: the place ahead of heavy frame is provided with the rubber header board, assembles spring between heavy frame and rubber header board; Install the spacing screw rod of several springs with slope tooth on heavy frame, the spacing screw front end of spring connects positioning plate, the retainer of assembling energy displacement on heavy frame, and the slope tooth of the spacing screw rod of retainer stop end connect spring, the other end connects actuating device.
2, bumper/spoiler according to claim 1 is characterized in that: the affixed stop collar in the end of the spacing screw rod of spring.
