Device for buffering striking force

Abstract

The invention discloses a device for buffering a striking force. The device comprises a collision part (1) and a fixing part (2), and is of an integral structure formed on one-time extrusion, wherein the collision part (1) comprises an inner layer (3) and an outer layer (4), the part between the inner layer (3) and the outer layer (4) is divided into cavities (6) by partition bars (5), and the outer layer of the collision part is circular-arc-shaped, and the arc surface protrudes outwards. According to the device for buffering the striking force, the manufacturing cost is low, the manufacturing is easy, the mounting is convenient, the structure is simple, particularly, the impact force caused by collision is buffered effectively, the damage to automobiles, ships or other machines adopting the device for buffering the striking force can be lowered, and the safety of people can be ensured.

Description

technical field [0001] The invention relates to a device for reducing collision force, in particular to a device for reducing collision force for vehicles and ships, such as vehicle bumpers or ship fenders, and is also suitable for other places that need to prevent collision force, such as expressway guardrails , Port guardrails, etc. Background technique [0002] Vehicles or ships are prone to collisions during use. When collisions occur, major accidents are often caused by unreasonable or no protective devices on the outside of the hull or car body, resulting in casualties and property losses. [0003] The 2011 China Automobile Industry Economic Operation Announcement released by the Ministry of Industry and Information Technology shows that in 2011, China's auto market achieved steady growth, and both auto production and sales exceeded 18.4 million units, setting a new global historical record. According to statistics from China Association of Automobile Manufacturers, C...
