Problems solved by technology
The main reason is that the metal bumper is heavy. If it is used, it will inevitably increase the weight of the vehicle body, and then increase the fuel consumption. Therefore, most manufacturers try not to use it, or use small-sized, light-weight bumpers
In addition, due to the high rigidity of the metal bumper, the cushioning effect is poor when encountering a collision, which leads to the expansion of accident losses.

Embodiment Construction
[0024] Such as figure 1 , figure 2 As shown, the motor vehicle protective block disclosed by the present invention is composed of an outer rubber block 1 and a bottom rubber block 2, and the two are stacked together. The two ends of the bottom rubber block 2 have holes 3 for easy installation, which can be directly connected with the automobile beam, longitudinal beam, chassis, body and other parts, which can effectively reduce the impact force from different directions, thereby improving the safety performance of the automobile.
[0025] Such as image 3 , Figure 4 As shown, the superposition of the outer rubber block 1 and the primer block 2 is achieved through the cooperation of the connecting pins 4 respectively located on the primer block and the outer rubber block and the corresponding connecting holes. That is, the connecting pin on the primer block cooperates with the connecting hole on the outer rubber block, or the connecting pin on the outer rubber block cooper...

The invention relates to the technical field of safe collision prevention of motor vehicles, in particular to a protection block of a motor vehicle and a manufacturing process thereof. The protection block is provided with an external rubber block and a bottom rubber block, wherein the elastic modulus of the bottom rubber block is more than that of the external rubber block; the two rubber blocks are superposed; the external rubber block mainly comprises the following raw materials: butadiene rubbers, natural rubbers, zinc oxide, stearic acid, vaseline, pine tar oil, sulfur and the like; and the bottom rubber block comprises the following raw material: polyurethaneWHT-1570IO. The manufacturing process comprises the steps of external rubber block processing, bottom rubber block processing and integral forming. The protection block and the manufacturing process have the following beneficial effects: the external rubber block and the bottom rubber block are respectively manufactured from two materials with different hardness; and the protection block can absorb the impact energy and buffer and resist strong impact and can inhibit resonance surge through interaction of the two rubber blocks, thus having good comprehensive collision defence effect.
Description
technical field [0001] The invention relates to the technical field of motor vehicle safety anti-collision, in particular to a motor vehicle protection block and a manufacturing process thereof. technical background [0002] The motor vehicle anti-collision products used in the market at present, its practical performance is unsatisfactory. Generally, automobile bumpers or improved bumpers in the traditional sense have unsatisfactory anti-collision effects, and are more decorative. The main reason is that the metal bumper is heavy. If it is used, it will increase the weight of the vehicle body, which will lead to an increase in fuel consumption. Therefore, most manufacturers try not to use it, or choose bumpers with small specifications and lightweight materials. In addition, due to the high rigidity of the metal bumper, the cushioning effect is poor when encountering a collision, which causes the expansion of the accident loss. Contents of the invention [0003] The obj...
