specific Embodiment approach 1

[0033] Specific implementation mode one: as figure 1 As shown, a bumper with anti-mis-collision and instantaneous impact resistance is installed on the car body bracket 9. The bumper includes a bumper body 1, a connecting rod shaft 2 and a buffer assembly. The buffer assembly is fixedly connected to the bracket 9. The bumper body 1 is movably connected to the buffer assembly through the connecting rod shaft 2. Car body support 9 is that the front portion of parts such as vehicle body or car chassis can be used as the structure that fixes, and bar body 1 is the part that protects automobile from the outside of bumper, and buffer assembly is the structure that plays buffering effect as the name suggests, when bar body 1 and After a slight short-stroke collision outside, the buffer assembly allows the bumper body 1 to retreat, so that the car does not have a rigid collision with the outside world, and plays a role in protecting the appearance of the bumper body 1. "Slight short-s...

specific Embodiment approach 2

[0043] Embodiment 2: The bumper includes a bar body 1 , a connecting rod shaft 2 and a buffer assembly, the buffer assembly is fixedly connected to the bracket 9 , and the bar body 1 is movably connected to the buffer assembly through the connecting rod shaft 2 . The lever body 1 includes a collision block 11 and a shaft seat 12. One end of the shaft seat 12 is fixedly connected with the collision block 11, and one end is provided with a shaft hole 121. One end of the connecting rod shaft 2 is inserted into the shaft hole 121, and one end is connected with the buffer assembly. The shaft hole 121 There is a first elastic body 122 inside, one end of the first elastic body 122 abuts against the end of the connecting rod shaft 2, and one end abuts against the bottom of the shaft hole 121, and the side wall of the shaft hole 121 is also provided with a pin hole 123, the pin hole 123 is provided with a slider pin 124 and a second elastic body 125, the slider pin 124 is installed in t...

Abstract

The invention discloses a bumper capable of preventing accidental collisions and resisting instantaneous impact. The bumper is installed on a vehicle body support, and comprises a bumper body, a connecting rod shaft and a buffering assembly, wherein the buffering assembly is fixedly connected to the support, the bumper body is movably connected to the buffering assembly through the connecting rodshaft, the buffering assembly can be two bumper bodies which are connected together through an oil way, and can also be a bumper body internally filled with a non-Newtonian fluid, and the flow of a working medium is realized through two pistons inside the buffering assembly. After a slight short stroke collision occurs between the bumper body and the outside, the buffering assembly allows the bumper body to retreat, so that no rigid collision occurs between a vehicle and the outside, and the effect of protecting the appearance of the bumper body is achieved; and the buffering assembly does notprovide a buffering function any more when a larger stroke or strong collision occurs between the bumper body and the outside, the connection between the bumper body and a vehicle body is changed tobe rigid, and the function of a traditional bumper is achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a bumper for preventing accidental collision and resisting instantaneous impact. Background technique [0002] The car bumper is a very important part of the car body. It not only has a decorative function, but also can absorb and alleviate the external impact when the car collides violently with the outside world, protecting the car body and the people inside the car. [0003] In the prior art, the bumper is rigidly installed on the vehicle body, and resists the impact force through its own structural rigidity, but sometimes the driver may make a mistake due to the distance judgment when parking against the wall or slowly parking to wait for traffic lights. A slight bump into the front object, although the main functional structure of the bumper will not be damaged, but the appearance of the bumper will be damaged. If the rigid structure and rigid fixing of the bumper are changed to a...
