Embodiment Construction

[0022] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0023] A non-load-bearing light truck front-end collision energy-absorbing system, mainly composed of figure 1 The energy-absorbing beam A at the front end of the girder in image 3 The secondary energy-absorbing beam B at the front end of the girder and Figure 5 The cab front end energy-absorbing longitudinal beam C is composed.

[0024] combine figure 1 , figure 2 As shown, the energy-absorbing beam A at the front end of the girder is mainly composed of the web 1 of the energy-absorbing beam and the outer plate 2 of the energy-absorbing beam. The thickness of the web 1 of the energy-absorbing beam and the outer plate 2 of the energy-absorbing beam are both 2.0mm, and the material is 340 / 590DP. To install the energy-absorbing beam A at the front end of the girder, first cut off the light truck girder 6 from the front position of the girder part br...

Abstract

The invention discloses a front-end collision energy absorption system of a non-loading type light truck. The front-end collision energy absorption system comprises a girder front-end energy absorption beam, a girder front-end secondary energy absorption beam and a cab front-end energy absorption longitudinal beam, wherein the girder front-end energy absorption beam comprises an energy absorption beam web plate and an energy absorption beam outer plate; a light-truck girder is cut off from the position in front of a girder part bracket where a vehicle body and the girder are suspended to the position of a front anti-collision C-shaped beam and is replaced with the girder front-end energy absorption beam; the girder front-end secondary energy absorption beam comprises a secondary energy absorption inner plate and a secondary energy absorption outer plate; a right-angle triangular shape is formed by surrounding the girder front-end energy absorption beam, the girder front-end secondary energy absorption beam and the front anti-collision C-shaped beam; a front-end energy absorption longitudinal beam outer plate of the cab front-end energy absorption longitudinal beam adopts a U-shaped section-variable panel with the height which is gradually increased from front to back; the front-end energy absorption longitudinal beam outer plate is used for covering and fixing a part, located on a cab front boarding, of a cab front-end floor longitudinal beam. Under the condition that the shape is not changed and the front-end energy absorption distance is not increased, the front-end collision energy absorption effect of the non-loading type light truck is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile anti-collision, and in particular relates to a front-end collision energy-absorbing system for non-load-bearing light trucks. Background technique [0002] The newly revised GB11551-2014 "Automobile Frontal Collision Occupant Protection" regulation put forward for the first time the requirements for light trucks to meet the frontal collision. For non-load-bearing light trucks in the current market, there are generally problems such as short front energy absorption distance, poor energy absorption effect and single force transmission path. , The front longitudinal beam is not easy to crush and deform to absorb impact energy, which makes it extremely difficult for this model to pass the above regulations. However, the manufacturer is unwilling to increase the energy-absorbing distance of the front end due to the constraints of the external shape and cost control factors. It is necessary to provi...
