Rear bumper be based on metal material, with the steel plate punched that thickness is more than 3 millimeters into U-lag steel, surface treatment chromium plating, with
Longitudinal beam is riveted or welded together, and has one section of larger gap with vehicle body, seems that an additional part up is taken a fancy to
Go very unsightly.
Automobile front/rear collision bumper is in addition to keeping original defencive function at present, also to pursue with the harmony of car body moulding with
It is unified, the lightweight of pursuit itself.The front/rear collision bumper of car is all that people are referred to as plastic bumper made of plastics.Due to
Plastic bumper is used made of hard plastic, so without preferable buffering effect, if vehicle front bumper arrangement
When being collided with other vehicles or building, then strong vibrations can be brought to the passenger on car, seriously can then hurt and multiply
Visitor.
For example, Chinese patent literature CN206067689U once disclosed a kind of automobile front beam, including bumper body,
The main protection plate that middle part is provided with the top of bumper body and the side protection board for being arranged on both sides, set on the safeguard of side
There is headlight standing groove, the headlight standing groove surrounding is provided with headlight shock-absorbing protecting block, car plate is provided with the main protection plate
Putting hole, the car plate putting hole surrounding are provided with LED standing groove, and the bumper body is provided at both ends with fog lamp placement
Groove, the fog lamp standing groove surrounding are provided with fog lamp shock-absorbing protecting block；The bumper body, main protection plate and side protection board are equal
It is made up of painting protective layer, painting layer, metallic plate fixed bed, elastic metal layer and protection bottom.And for example CN205997830U
Disclose a kind of new automobile front bumper, including shell, bumper body, reinforcement, cushion, energy absorbing component, connecting plate,
Front longitudinal, car puller hook mounting hole, car puller hook, are provided with car puller hook mounting hole on the upside of the shell, in the car puller hook mounting hole
Car puller hook is installed, the car puller hook side connects through cushion with bumper body, and the car puller hook is Collapsible structure,
The car puller hook includes towing hook hole, expansion link, top cover, and car puller hook mounting hole, car puller hook are offered on shell of the present utility model
Car puller hook is installed in mounting hole, the car puller hook includes expansion link, and expansion link is Collapsible structure, opens top cover when deployed,
Expansion link is pulled out, rope is tied up in towing hook hole, is easy to the dragging of automobile, because car puller hook and bumper body are connected to one
Rise, be easy to movement of the utility model with motor vehicles bodies during dragging.
Although each especially feature and advantage, its collision prevention function is unsatisfactory for above-mentioned front bumper.Therefore, how to make
Make a kind of bumper bar that can be brought and preferably buffer, turn into current need most and solve the problems, such as.
