For a better understanding of the present teachings, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Examples
As shown in figures 1 to 3, the foam crash-proof energy absorption block for the automobile bumper comprises
The buffer structure comprises a first buffer block 10 made of foaming materials, wherein two ends of the first buffer block 10 are provided with arc structures, and grooves 11 with outward openings are arranged on the first buffer block 10 at intervals; the second buffer block 12 made of foaming material is combined with the first buffer block 10, and the density of the second buffer block 12 is greater than that of the first buffer block 10; the second buffer block 12 is provided with a honeycomb structure, and the upper part and the lower part of the inner side of the second buffer block 12 are respectively extended inwards to form a mounting plate 13; the upper mounting plate 13 and the lower mounting plate 13 and the second buffer block 12 jointly form a mounting groove 14, and the mounting plates 13 are bent to form a clamping part 15; the buffer device 16 is arranged in the groove 11, and the buffer device 16 is lower than the opening of the groove 11; and the skin 17 is wrapped on the first buffer block 10 and the second buffer block 12. The densities of the first and second buffer blocks 10 and 12 are different, and thus the buffer levels of the first and second buffer blocks 10 and 12 are different. The density of the first buffer block 10 is less than that of the second buffer block 12, so that the foam anti-collision energy absorption blocks used in the automobile bumper have different buffering effects, and therefore, the buffering effect is better, and pedestrians can be better protected. The first buffer block 10 with low density is firstly stressed during collision, so that pedestrians can be better protected during collision. The first buffer block 10 firstly buffers, then the buffer device 16 in the groove 11 on the first buffer block 10 continuously absorbs energy, and releases energy when reaching a set value, so that the foam anti-collision energy-absorbing block used in the automobile bumper has higher safety. Therefore, the first buffer block 10, the second buffer block 12 and the buffer device 16 all have the buffer effect, so that multi-stage buffering is realized, and the safety is higher. The mounting groove 14 makes the foam anti-collision energy-absorbing block used in the automobile bumper only needs to be clamped into the mounting groove 14 when being mounted, and other metal is not needed for auxiliary mounting, so that the mounting is convenient, and pedestrians can be better protected. The first buffer block 10 of covering 17 parcel and second buffer block 12 for first buffer block 10 and second buffer block 12 still are a whole after being collided in the time of the collision, can not drop because of cracked, can continue to exert the effect of buffering, and then make the effect of buffering better, and the security is higher. The two ends of the first buffer block 10 have a circular arc structure, and the circular arc structure can protect the side surface and provide more comprehensive buffering. The design of joint portion 15 makes mounting groove 14 be difficult to drop when installing with the car bumper, and is convenient, simple.
Preferably, the foam anti-collision energy-absorbing block used in the automobile bumper is made of the same or different foaming materials of the first buffer block 10 and the second buffer block 12, and the foaming material is one of polyethylene, polypropylene and polyurethane.
Preferably, the first buffer block 10 has a circular arc structure in the middle and protrudes outwards. The structure of the circular arc can be decomposed by the collision force of the structure of the circular arc when being collided, and the buffering effect can be better.
Preferably, in the foam crash-absorbing block for use in a bumper of an automobile, the cushioning device 16 is an air bag or a water bag. When the pressure applied to the cushioning device 16 exceeds a set value, the cushioning device will rupture to release energy, thereby achieving the effect of protecting pedestrians.
Further, the foam anti-collision energy absorption block used in the automobile bumper is characterized in that a cover plate 18 covers the groove 11, and the manufacturing material of the cover plate 18 is the same as that of the first buffer block 10. The cover plate 18 can prevent the buffer device 16 from shaking, and the surface of the first buffer block 10 is smooth and has strong integrity after being covered.
To sum up, the utility model discloses a design focus lies in, and it is different because the density of first buffer block 10 and second buffer block 12, consequently first buffer block 10 and second buffer block 12 combine the back, have multistage buffering effect. Meanwhile, the second buffer block 12 has a honeycomb structure, and the honeycomb structure has good buffering performance, so that the first buffer block 10 and the second buffer block 12 are combined to achieve better buffering effect, are safer and can better protect pedestrians. The cushioning device 16 in the groove 11 of the first cushion block 10 can absorb energy during a collision, thereby adding a heavy cushioning protection. Therefore, the foam anti-collision energy absorption block used in the automobile bumper has triple buffering, so that the buffering effect is good, and the safety is higher.
The first buffer block 10 of covering 17 parcel and second buffer block 12 for first buffer block 10 and second buffer block 12 still are a whole after being collided in the time of the collision, can not drop because of cracked, can continue to exert the effect of buffering, and then make the effect of buffering better, and the security is higher.
Two piece upper and lower mounting panels 13 constitute a mounting groove 14 with second buffer block 12 jointly, and mounting panel 13 bending forms a joint portion 15 for only need with mounting groove 14 card go into car bumper can in the installation, need not the supplementary installation of other metals, consequently simple to operate, protection pedestrian that can be better.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
