specific Embodiment approach 1

[0017] Specific Embodiment 1: The energy-absorbing box based on the pneumatic muscle in this embodiment includes an energy-absorbing box 1, a pneumatic muscle 2 and a fixing seat 3, and at least one guide rail hole is opened in the box body along the longitudinal direction of the energy-absorbing box 1, and the guide rail hole A pneumatic muscle 2 is installed in the center, and an air guide tube 6 is connected to the pneumatic muscle 2. The axial direction of the pneumatic muscle 2 is parallel to the longitudinal direction of the energy-absorbing box 1. One end of the pneumatic muscle 2 is inserted into the fixing seat 3 and fixed by a rivet 4. The pneumatic muscle The other end of 2 is placed in the guide rail 5 and slides in the guide rail 5 along the constraint direction with the active contraction of the pneumatic muscle 2. There is a gap to accommodate the expansion of the pneumatic muscle 2 between the pneumatic muscle 2 and the hole wall of the guide rail hole.

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the crash box 1 has a bellows structure.

[0021] The section of the corrugated crash box described in this embodiment is a cylindrical structure with continuous corrugations.

specific Embodiment approach 3

[0022] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 or 2 is that a guide rail hole is opened in the box body along the longitudinal direction of the energy-absorbing box 1, and the pneumatic muscle 2 and the shaft of the pneumatic muscle 2 are installed in the guide rail hole. To coincide with the central axis of the crash box 1.

[0023] The schematic diagram of the structure of the energy-absorbing box based on the pneumatic muscle described in this embodiment is as follows: Figures 1 to 3 shown.

Abstract

The invention discloses an energy absorption box based on a pneumatic muscle, and relates to an energy absorption box. The energy absorption box based on the pneumatic muscle aims at solving the problems that the energy absorption performance of an existing energy absorption box needs to be improved, and the weight of the existing energy absorption box is large. The energy absorption box based onthe pneumatic muscle comprises an energy absorption box body, the pneumatic muscle and a fixing base, wherein at least one guiding rail hole is formed in the box body in the longitudinal direction ofthe energy absorption box body, the pneumatic muscle is installed in the guiding rail hole, the axial direction of the pneumatic muscle is parallel to the longitudinal direction of the energy absorption box body, one end of the pneumatic muscle is inserted into the fixing base and fixed through rivets, the other end of the pneumatic muscle is arranged in guiding rails and slides in the constraintdirection in the guiding rails along with active contraction of the pneumatic muscle, and a gap for containing pneumatic muscle expansion is reserved between the pneumatic muscle and the hole wall ofthe guiding rail hole. According to the energy absorption box based on the pneumatic muscle, a pneumatic muscle mechanism is introduced into the energy absorption box, active contraction of the pneumatic muscle is excited in a self-adaption mode through a pneumatic control system, the whole rigidity of the energy absorption box system can be changed, and the mass of the pneumatic muscle is light.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an energy-absorbing box. Background technique [0002] At present, various types of vehicles, such as automobiles, trains, etc., are more prone to collisions and accidents due to the increasing speed of operation. The violent collisions in such accidents will cause unbearable losses to the lives and properties of the public. With the improvement of the economy and living standards, people are increasingly using cars as a means of travel and as an important part of the passive safety of cars. When a collision occurs, the energy-absorbing box absorbs the energy transmitted by the anti-collision beam through a series of deformations. , and when the energy exceeds its bearing range, the energy is transferred to other body safety components in time, so as to reduce the damage to the body and the injury of personnel in collision accidents. With the increasing number of...
