Abstract
The utility model provides an automobile collision energy-absorbing device. An anti-collision rod is arranged at the front part of an automobile body by an anti-collision rod oil cylinder or a dowel bar, and the front part of the automobile body is connected with an energy-absorbing oil cylinder or an elastic steel plate by an oil duct or the dowel bar; and the elastic steel plate or the energy-absorbing oil cylinder are fixed on a frame of the automobile body. The automobile collision energy-absorbing device can be used for transferring the backward acting force generated when the automobile body is collided to the elastic steel plate by the anti-collision rod through the oil duct or the dowel bar, so that the elastic steel plate is deformed for absorbing the energy generated by collision, thus protecting the safety of the automobile body and passengers. The automobile collision energy-absorbing device has good effects of energy absorption and anti collision, and is suitable for being installed and used on the moving vehicles.
Description
Technical field
The utility model provides the safety device of mechanical field, specifically the automobile impacting energy absorption device.
Background technology
Before the utility model proposes, automobile adopts built-in crash bar aspect crashproof, protection occupant, make automobile when being clashed into, and makes the car body distortion, thus the protection occupant.But because its mechanism is hidden in the vehicle frame of car body, be subjected to the restriction of vehicle frame shape and car body outward appearance,, therefore when car body bumps, still can destroy car body so can not fully reach the absorption Impact energy, limited to occupant's protection abilities.
Summary of the invention
In order to overcome the shortcoming of existing anti-collision device for automobile, the utility model provides the automobile impacting energy absorption device.This device solves the technical purpose of automobile impacting energy-absorbing by the effect of buffer arm and energy-absorbing oil cylinder and elastic plate.
The scheme that the utility model technical solution problem is adopted is: the front portion at car body is equipped with buffer arm by buffer arm oil cylinder or dowel bar, and be connected with energy-absorbing oil cylinder or spring steel plate by oil guide pipe or dowel bar, spring steel plate or energy-absorbing oil cylinder are fixed on the vehicle body frame.
Good effect: the application force backward that the utility model is produced when by buffer arm car body being subjected to clashing into is delivered on the spring steel plate by oil guide pipe or dowel bar, makes its distortion, absorbs Impact energy, thus protection car body and occupant.Has the effective effect of energy-absorbing anti-collision.Suit on driving vehicle, to install and use.
Description of drawings
Fig. 1 is the utility model embodiment 1 structure principle chart
Fig. 2 is the utility model embodiment 2 structure principle charts
Among the figure, 1. car body, 2. buffer arm, the 2.1. dowel bar, 3. the buffer arm oil cylinder 4. connects oil pipe, 5. energy-absorbing oil cylinder, 6. spring steel plate.
The specific embodiment
By at car body installed in front buffer arm; and the thrust backward that is produced will clash into the time is transmitted its thrust backward by buffer arm oil cylinder and oil guide pipe or dowel bar; act on the energy-absorbing oil cylinder; the energy-absorbing oil cylinder acts on the power of being transmitted on the spring steel plate again; make the spring steel plate distortion; absorb the energy that impact produced, thereby keep indeformable in the car body, protection vehicle and occupant's safety.
Embodiment 1
According to shown in Figure 1, two buffer arm oil cylinders, captive joint buffer arm 2 on oil cylinder are installed in the front portion of car body 1, be connected with oil guide pipe 4 at the oil cylinder opposite side, and be connected with energy-absorbing oil cylinder 5, the energy-absorbing oil cylinder is installed in the middle part of spring steel plate 6, and unisexuality steel plate two ends are fixed on the vehicle frame of car body.
According to shown in Figure 2, the end side that connects bar in the buffer arm 2 ， Zai Xu by two dowel bars 2.1 in car body 1 front portion is connected with the two ends of spring steel plate 6, and spring steel plate is installed on the energy-absorbing oil cylinder, and its tail end is installed in the rear end of vehicle body frame.
Spring steel plate is the plate object that is the convex-concave bending, and when the energy-absorbing oil cylinder was fixed on the front side of spring steel plate, spring steel plate was convex, and when the energy-absorbing oil cylinder was fixed on the rear side of spring steel plate, spring steel plate was spill.
When spring steel plate was subjected to clashing into, the effect that is subjected to energy-absorbing oil cylinder or dowel bar produced elastic deformation, thereby absorbed the destructive effect that is caused with buffering percussive force.
Claims (2)
1, automobile impacting energy absorption device, it is characterized in that: the front portion at car body (1) is equipped with buffer arm (2) by buffer arm oil cylinder (3) or dowel bar (2.1), wherein be connected with energy-absorbing oil cylinder (5) by oil guide pipe with buffer arm oil cylinder (3), the energy-absorbing oil cylinder is fixed on the middle part of spring steel plate (6), and the spring steel plate two ends are fixed on the vehicle body frame; And dowel bar is connected the two ends of spring steel plate, and spring steel plate middle part institute bonded assembly energy-absorbing oil cylinder is fixed on the vehicle body frame.
2, automobile impacting energy absorption device according to claim 1, it is characterized in that: spring steel plate is the plate object that is the convex-concave bending, and when the energy-absorbing oil cylinder was fixed on the front side of spring steel plate, spring steel plate was convex, when the energy-absorbing oil cylinder was fixed on the rear side of spring steel plate, spring steel plate was spill.
