Problems solved by technology

However, the main function of the front sub-frame of the current vehicle is to connect the front axle with the engine, and at the same time serve as the fulcrum of the front suspension to slow down the vibration of the vehicle body during driving. Basically, there is no energy-absorbing design. The structural integrity of the cabin does not contribute much to crash safety

Embodiment Construction

[0020] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0021] like Figure 1 to Figure 4 As shown, an energy-absorbing front sub-frame is a double "Y"-shaped frame-type front sub-frame. On the basis of not affecting the loading and installation requirements of the front sub- The front section of the longitudinal beam assembly on the left and right sides of the subframe is equipped with energy-absorbing grooves to fully absorb energy, and the rear section is designed with a bifurcated structure, which can transmit loads stably on the basis of ensuring the energy absorption of the front section.

[0022] The specific structure of the energy-absorbing front sub-frame is as follows: it includes the front beam assembly 1, the rear beam assembly 2, the right longitudinal beam assembly 3 and the left longitudinal beam assembly 4; among them, the right lon...

Abstract

The invention discloses an energy-absorbing type front subframe comprising a front beam assembly, a rear beam assembly, a right girder assembly and a left girder assembly, wherein the right girder assembly and the left girder assembly are arranged between the front beam assembly and the rear beam assembly, the front section of the right girder assembly and the front section of the left girder assembly are respectively provided with an energy-absorbing groove, and the rear section of the right girder assembly and the rear section of the left girder assembly are in bifurcate structures. When the front portion of a vehicle is collided, the front sections of the girder assemblies can generate stable step-by-step collapse under a guide function of the energy-absorbing grooves and a strong supporting function of the bifurcate structures of the rear sections of the girder assemblies, and can fully absorb energy. Meanwhile, the rear sections of the girder assemblies are not prone to being bent and deformed and force can be stably transmitted to a door sill and a bottom plate girder so that the energy can be absorbed and consumed, completeness of a passenger cabin can be maintained, and life safety of passengers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile frames, in particular to an energy-absorbing front auxiliary frame. Background technique [0002] During a vehicle frontal collision, protecting the life safety of the occupants is the goal of passive safety design, and maintaining the structural integrity of the occupant compartment is the core of occupant protection. Ensuring the integrity of the passenger compartment requires the vehicle's front structure to adequately absorb crash energy. [0003] When the front of the vehicle collides, relying entirely on the front longitudinal beams of the vehicle body frame cannot fully absorb the energy during the frontal collision of the vehicle. Therefore, it is necessary to provide a second or even a third longitudinal load transfer path for the body structure to dissipate the impact energy. It is a practical and effective means to use the front subframe to achieve load transmission and absorb more ...
