Abstract
The utility model is mainly applied in cars and other motor vehicles to decrease the accidental colliding force and protect the cabin and the body, which comprises 1 a rubber cushion, 2 a steel protective board, 3 springs, 4 a support rack board, and 5 a support rack. The springs decide the effective buffer force of the whole bumper, that's to say the resultant force of the six springs equals to the effective elastic force that the colliding enables to alleviate. The effective elastic force is requires to have a direct ratio to the total weight of the car and usually about 80 percent of the total weight. The ratio can be adjusted. The steel protective board and the support rack board are required to keep from deforming under two-time effective elastic force. The support rack used to connect the bumper with the main car girder is required to bear above three-time effective elastic force. The effective rebound range is adjusted in the scale of 6 cm to 10 cm according to the vehicles. The location of the bumper under maximum compressing is required to be at least 5 cm longer than the car body for prevent the car body from shock. The utility model achieves the best efficiency when the vehicle with the noble bumper meets knocking, reversing or colliding in medium/low speed.
Description
Affiliated technical field:
The utility model relates to the bumper system of installing on the car, can slow down the destructive force of car when being subjected to clashing into and outer the decoration.
Background technology:
Present known car bumper is many to be made by plastic material, and fragile, though play decoration function, headstock, tailstock bump in traffic accident itself is frangible, again automobile itself is not had the too big effect of buffering and protection, easily the automobile and the person is caused damage.
Summary of the invention:
In order to overcome the rapid wear unprotect of existing car bumper, the utility model designs a kind of bumper/spoiler and not only rises certain ornamentally but also can slow down impact, has protected whole damageable zone of car and main body again.
The technical solution adopted in the utility model is: at the bumper/spoiler skin, use flexible soft rubber shell, be contained on the steel integral protection plate, by the damping spring that 6 or 8 symmetries are installed, be connected a whole steel and install on the frame plate, pass through mounting bracket again, be connected on the load-bearing main body beam of car bottom, make the headstock and the tailstock when being subjected to extraneous bump,, behind the abundant damping, buffering of spring impulsive force is born among car integral body by the soft rubber shell.
The beneficial effects of the utility model are: playing the equal decoration of outward appearance simultaneously, can be to the impact damping and the buffering at bumper/spoiler place, thus reduce destruction to automobile and personal safety, and the repetition durability is arranged.
Description of drawings:
Below in conjunction with accompanying drawing and example, the utility model is further specified.
Fig. 1 is first kind of design-calculated elevation profile of bumper/spoiler constructional drawing.
Fig. 2 is the internal structure section plan of Fig. 1.
Fig. 3 is second kind of design-calculated elevation profile of bumper/spoiler constructional drawing.
Fig. 4 is the side sectional view of first kind of design drawing 1.
Among the figure 1, rubber fender, 2, the steel guar plate, 3, damping spring, 4, frame plate is installed, 5, mounting bracket.
The specific embodiment:
In Fig. 1 rubber fender (1), steel guar plate (2) damping spring (3) is installed frame plate (4) and mounting bracket (5) opsition dependent is connected to an integral body with screw, rubber fender (1) is answered the flexible and wear-resisting shell decoration function that rises again, total effective pressure of 6 or 8 symmetrical mounting spring should be directly proportional with the total weight of various installation car, should debug between spring pressure 80% car weight amount.Steel guar plate (2) and frame plate (4) is installed and mounting bracket (5) should select for use be difficult for deformation strength much larger than spring pressure and automobile total weight the sheet metal more than 3 times.
Damping spring in Fig. 3 (3) has adopted alternative arched spring.Other design is basic identical.
Mounting bracket in Fig. 1 (5) when headstock, the tailstock are installed, answer direct connection the main body bearing beam of car to make it main body the most nearby stressed.
Claims (5)
1, this car bumper is by the installation that is linked in sequence of rubber fender, steel guar plate, damping spring, installation frame plate, mounting bracket, it is characterized in that shell is elastomeric rubber fender, protect and be rolled in steel guar plate skin, damping spring is installed on guar plate and installs between the frame plate, body pillar that frame plate is connected car by hard metal mounting bracket is installed the most nearby.
2, according to the described bumper/spoiler of claim 1, it is characterized in that: rubber fender is wrapped in whole bumper/spoiler skin, plays to slow down and impacts and the top layer rubs and the bumper skin effect.
