Abstract
The utility model discloses a passenger-protecting beam for a sports utility vehicle (SUV). The passenger-protecting beam comprises a shank beam and a thigh beam, wherein the shank beam is arranged on a lower beam of a water tank, and the thigh beam is arranged on an upper beam of the water tank. By means of the technical scheme, compared with the prior art, the passenger-protecting beam meets the requirement on protecting the leg of a passenger in collision. When the shank of the passenger collides with and the vehicle, foams are compressed to play a role of buffering and energy absorption; simultaneously, the shank beam deforms, the load is transferred, the impact speed is lowered, and when the movement reaches a certain degree, the lower portion of the shank of the passenger is bounced up, thereby reducing the bending angle of the leg; and after the shank is bounced up, the thigh of the passenger moves forward to contact grids, and at this time, the thigh beam prevents the legs from moving forward, thereby effectively controlling the bending angle of the leg and achieving the aim of protecting the leg of the passenger.
Description
Technical field
The utility model relates to automobile component, and specifically, the utility model relates to a kind of pedestrian protecting crossbeam of the SUV of being used for vehicle.
Background technology
China's auto trade develop rapidly, automobile pollution increases fast, but because China's road still belongs to the mixed type traffic, self-propelled vehicle, pedestrian many places are in same road, this has just increased the probability of China pedestrian and the generation of collision of motor-driven vehicles accident.According to the data display of China Automotive Technology & Research Center, China's toll on traffic occupies first place in the world for several years running, and once surpasses 100,000 people, and wherein pedestrian's dead ratio surpasses 40%.Therefore, vehicle seems extremely important to pedestrian's injury to the development pedestrian protection in the accident to reduce.
The fender guard of shank generally is on the position of safety lever, to add foam under the pedestrian protecting, is used for buffering and energy-absorbing to shank; And add a shank crossbeam in the lower end also is common way, is mainly used in the control knee angle of bend.But for the SUV vehicle, because angle of attach is bigger, the position of shank crossbeam is very high, and at this moment the shank crossbeam can not well play the purpose that reduces angle of bend, and this just needs to adopt a kind of new way to control knee angle of bend.
The utility model content
The utility model technical matters to be solved provides a kind of pedestrian protecting crossbeam of the SUV of being used for vehicle, to reach the purpose that in collision, can protect pedestrian's shank.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of pedestrian protecting crossbeam of the SUV of being used for vehicle, comprise the shank crossbeam that is installed on the water tank cross sill, and comprise that also another is located at the thigh crossbeam on the water tank entablatrance.
Said thigh crossbeam is to be made up of the hollow tubular of two arcs of bonded assembly up and down.
The bending direction of said hollow tubular is consistent with the bending direction of said shank crossbeam.
Two described hollow tubulars are to stagger to be provided with in the horizontal direction.
The material of said thigh crossbeam is plastics.
The material of said shank crossbeam is plastics.
The utility model adopts technique scheme, compared with prior art, satisfied the SUV vehicle can be protected pedestrian's shank in collision requirement, and when shank and collision happens, foam is compressed the effect of playing buffering energy-absorbing instantly; Simultaneously, the shank crossbeam deforms, and with loading transfer, reduces velocity of impact, moves to certain phase shank crossbeam and is upspring in the shank bottom, has reduced angle of bend; And after shank upspring, thigh travelled forward and contacts with grid, and at this moment the thigh crossbeam blocks shank and travels forward, thereby actv. has been controlled angle of bend, reaches the purpose of shank under the protection pedestrian.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the thigh crossbeam of the utility model;
Fig. 3 is the A-A cutaway view among Fig. 2;
Fig. 4 is the side-looking structural representation of the thigh crossbeam of the utility model;
Mark among the above-mentioned figure is: 1, water tank entablatrance; 2, thigh crossbeam; 3, bumper/spoiler foam; 4, shank crossbeam; 5, water tank cross sill.
The specific embodiment
As shown in Figure 1, a kind of pedestrian protecting crossbeam that is used for the SUV vehicle of the utility model comprises that the shank crossbeam 4 that is installed on the water tank cross sill 5 is located at the thigh crossbeam 2 on the water tank entablatrance 1 with another.Thigh crossbeam 2 combines bumper/spoiler foam 3 and shank crossbeam 4, constitutes pedestrian protection, is used for protecting pedestrian's shank.Bumper/spoiler foam 3 plays the effect of energy-absorbing buffering, can effectively reduce the acceleration/accel of shank; Instantly when shank and collision happens, foam is compressed the effect of playing buffering energy-absorbing; Simultaneously, shank crossbeam 4 deforms, and with loading transfer, reduces velocity of impact, moves to certain phase shank crossbeam 4 and is upspring in the shank bottom, has reduced angle of bend; And after shank upspring, thigh travelled forward and contacts with grid, and at this moment thigh crossbeam 2 blocks shank and travels forward, thereby actv. has been controlled angle of bend, reaches the purpose of shank under the protection pedestrian.
The structure of concrete thigh crossbeam 2 is described below:
(1) like Fig. 2, Fig. 3 and shown in Figure 4; It is that the 20mm hollow tubular is formed by connecting up and down that thigh crossbeam 2 adopts two external diameters; Guaranteed can meet the demands on the intensity, can not block the air inlet of grid simultaneously again because cross-sectional area is big, overall beam adopts lighter plastic material; The shape of crossbeam can be done camber along vehicle structure, and promptly the bending direction of the bending direction of hollow tubular and shank crossbeam 4 is consistent, and two hollow tubulars are to stagger to be provided with in the horizontal direction.
(2) as shown in Figure 1, thigh crossbeam 2 is to be installed on the water tank entablatrance 1 through support, is used for controlling knee angle of bend in collision, and through the CAE checking computations, this crossbeam actv. in collision process has blocked huckle and travelled forward, and knee angle of bend significantly reduces.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
Claims (6)
