Abstract
The utility model provides an anti-collision structure for car door, which is longitudinally welded with an anti-collision beam on the skin welding assembly of the car door to strengthen the anti-collision performance of the car door. The two ends of the anti-collision beam are joint and fixedly welded with the skin welding assembly of the car door via a big plane structure, the middle of the anti-collision beam is provided with stiffeners, and the stiffeners are two stiffeners in parallel that penetrate the beam. The car door anti-collision strength is strengthened via the structures, so the car door anti-collision structure can effectively absorb the kinetic energy from lateral collision, guarantee the safety of front-row driver and passengers, and has excellent welding joint craftwork.
Description
Technical field
The utility model belongs to the auto body collision protection structure.
Background technology
Along with the development of society, people are more and more higher to the safety performance requirement of car, require it can bear tests such as strict central collision, side impact, and chaufeur and passenger's safety is guaranteed.In order to satisfy the side impact requirement, normally the longeron of vehicle side is strengthened design, car door is not then done too much must be considered, make car door become crash-proof weak link.
The car door anti-collision crossbeam that claims us to design following structure strengthens the crashproof function of car door.Actv. has guaranteed the anti-collision energy absorption performance of car door on the structure.
Summary of the invention
The purpose of this utility model is to provide a kind of sedan door collision protection structure at the deficiency of prior art existence, makes car door opposing intensity when being hit big, and energy-absorbing effect is good, helps guaranteeing chaufeur and passenger's safety.
The technical solution of the utility model is as follows:
A kind of sedan door collision protection structure includes car door inside panel welding assembly, and horizontal welding has a crashproof crossbeam on car door inside panel welding assembly, in order to increase the crashworthiness of car door.
The two ends of crashproof crossbeam are welded the part overlap joint welding that links to each other on the assembly with big planar structure and car door inside panel and are fixed, and the overlap joint gap is little, firm welding.
Is provided with reinforced rib in the middle of the crashproof crossbeam, and reinforced rib is two arranged side by side, crosses the crossbeam length overall, make crashproof beam strength height like this, energy-absorbing effect is obvious.
Can increase car door anti-collision intensity by these structures, actv. absorbs the kinetic energy from side collision.Guarantee front-seat chaufeur and passenger's safety, and had good welding attaching process.
Description of drawings
Fig. 1 is a sedan door collision protection structure scheme drawing;
Fig. 2 is the A-A cross section structure scheme drawing of crashproof crossbeam.
The specific embodiment
Referring to Fig. 1, the sedan door collision protection structure includes car door inside panel welding assembly 1 and crashproof crossbeam 2, and crashproof crossbeam 2 horizontal welding are on car door inside panel welding assembly 1, the welding two ends are big planar structure A, B, and are fixing with the part overlap joint welding that links to each other on the car door inside panel welding assembly 1.
Referring to Fig. 2, be provided with two reinforced ribs 3 arranged side by side in the middle of the crashproof crossbeam 2, pass across the crossbeam length overall.
