One or more embodiments of this description disclose a car front end protector, including crossbeam 1, the place ahead of crossbeam 1 is provided with a plurality of bumpers 3, and a plurality of bumpers 3 are arranged along crossbeam 1's length direction equidistance, bumper 3 articulates towards crossbeam 1's one side both ends has connecting rod 7, two connecting rod 7 is "eight" font and distributes, crossbeam 1 is fixed with slide rail 2 towards one side of bumper 3, slide rail 2 is on a parallel with crossbeam 1's length direction, connecting rod 7 is close to the one end of slide rail 2 and articulates there is slider 10, slider 10 is located slide rail 2 upper end and rather than sliding connection, a plurality of springs of a fixedly connected with 8 between bumper 3 and crossbeam 1.

As shown in fig. 1-3, this car front end protector includes crossbeam 1, crossbeam 1 the place ahead is provided with a plurality of bumpers 3, bumper 3 arranges along 1 length direction equidistance of crossbeam, bumper 3 sets up independently, non-fixed connection between the adjacent bumper 3, bumper 3 articulates towards one side both ends of crossbeam 1 has connecting rod 7, two connecting rod 7 are "eight" font, still be fixed with slide rail 2 on the crossbeam 1, slide rail 2 sets up along 1 length direction of crossbeam, 2 accessible bolted connection's of slide rail mode and crossbeam 1 fixed connection, connecting rod 7 is close to the one end of slide rail 2 and articulates there is slider 10, slider 10 sets up on slide rail 2, slider 10 can be fixed with a plurality of springs 8 between slide bumper 3 and the crossbeam 1 along the length direction of slide rail 2.

The use principle of the front bumper 3 of the present invention is: when the vehicle front end takes place local collision, only can strike local bumper 3, and bumper 3 not in the striking area is then not influenced, and bumper 3 receives the striking back, bumper 3 moves towards crossbeam 1, because the supporting role of two connecting rods 7, make the power of bumper 3 striking point dispersed, the even impact force that absorbs bumper 3 of a plurality of springs 8 simultaneously, bumper 3 can reduce the impact force to crossbeam 1 when striking crossbeam 1 like this, enlarge striking area, reduce crossbeam 1 damage degree, and every bumper 3 independently sets up, in the maintenance process after striking like this, change the damage bumper 3 can, need not whole change.

Compared with the traditional bumper 3 of the automobile, the front bumper 3 of the invention reduces the maintenance difficulty and the maintenance cost, has good protection effect and is suitable for standardized production.

In some optional embodiments, the bumper 3 is rectangular plate-shaped, the number of the springs 8 between each bumper 3 and the cross beam 1 is four, and four springs 8 are respectively fixed at four corners of the bumper 3, so that the buffering effect and the uniformity are improved.

In some alternative embodiments, a second spring 9 is fixed between two sliders 10 at the proximal ends of two adjacent bumpers 3, two fixing plates 4 are arranged at two ends of the sliding rail 2, and a second spring 9 is fixed between two sliders 10 at the distal ends of two bumpers 3 at the end of the cross beam 1 and two fixing plates 4 respectively.

When a local collision occurs, the bumper 3 moves towards the cross beam 1, the two sliders 10 move away from each other, the first spring 8 absorbs collision energy, and when the sliders 10 move away from each other, the springs between the sliders 10 and the adjacent sliders are compressed, so that the collision energy is further absorbed and alleviated.

In some optional embodiments, a plurality of mounting holes 14 aligned with the center of the bumper 3 are formed in the cross beam 1, a piston cylinder 12 is embedded into the mounting holes 14, a piston 11 connected in a sliding manner is arranged inside the piston cylinder 12, a piston rod 6 is arranged on one side, facing the bumper 3, of the piston 11, a plurality of avoidance ports 17 aligned with the center of the bumper 3 are formed in the slide rail 2, the piston rod 6 penetrates the avoidance ports 17 and is connected with the middle of the bumper 3, air bags 15 fixed on the slide rail 2 are arranged on two sides of the avoidance ports 17, one end, far away from the bumper 3, of the piston cylinder 12 is connected with two inflation tubes 13, the two inflation tubes 13 penetrate the cross beam 1 and are respectively communicated with the two air bags 15, an exhaust pipe 16 is arranged on the air bags 15, and an outlet sleeve of the exhaust pipe 16 is provided.

When striking, bumper 3 moves towards crossbeam 1, piston rod 6 drives piston 11 and moves towards piston rod 6 bottom, along with piston 11's removal, the inside air of piston rod 6 is by gas tube 13 entering gasbag 15 in, make gasbag 15 inflation, bumper 3 strikes on gasbag 15 earlier, the film of blast pipe 16 export cover is disposable, after bumper 3 struck gasbag 15, the inside air breaks the film and slowly releases, gasbag 15 becomes flat simultaneously, gasbag 15 further cushions bumper 3, the reduction is to crossbeam 1's destructiveness.

In some alternative embodiments, the piston rod 6 is hinged to both ends of the bumper 3 and the piston 11, so that the piston rod 6 has a certain rotatability, so that when the impact angle is not in a front direction towards the bumper 3, the piston rod 6 can urge the piston 11 to move towards the bottom of the piston cylinder 12 even if the piston rod is inclined, and the air bag 15 is expanded.

In some alternative embodiments, a flame-retardant pad 5 is fixed to the side of the bumper 3 facing away from the cross member 1, so as to reduce the risk of combustion occurring after an impact.
