[0002] With the popularity of automobiles, people have higher and higher requirements for automobile safety. Among them, the anti-collision beam device on the car is a device that absorbs collision energy when the vehicle is hit.

DETAILED DESCRIPTION
[0016] A buffer automobile anti-collision beam, the specific structure of which is as follows Figure 1 As shown, it includes a buffer beam 1 and a main beam 9 located inside the buffer beam, and buffer springs 3 are fixedly installed at both ends of the buffer beam and the main beam. During the specific installation, a spring mounting seat 15 can be fixedly installed on the buffer beam and the main beam respectively, and a limiting column 14 is provided on the spring mounting seat, and then the buffer spring is mounted on the two limiting columns.
[0017] Two buffer beam limiting grooves 4 are provided in the middle of the inner surface of the buffer beam, and two main beam limiting grooves 8 are provided on the outer surface of the main beam. Buffer beam sliders 7 are respectively installed in the two buffer beam limiting grooves, and main beam sliders 11 are respectively installed in the two main beam limiting grooves. A buffer beam arc spring piece 6 is fixedly connected between the two buffer beam sliders. The buffer beam arc spring piece and the buffer beam slider can be fixed by welding, or by bolts or other fixing methods.
[0018] The main beam arc spring piece 10 is fixedly connected between the two main beam sliders, and the buffer beam arc spring piece and the main beam arc spring piece are arranged back to back to form a butterfly shape. The main beam arc spring piece and the main beam slider can be fixed by welding, bolts or other fixing methods.
[0019] Since the arc-shaped spring piece of the buffer beam and the arc-shaped spring piece of the main beam are arranged back to back to form a butterfly shape, no connection is required between the two, so the structure is relatively simple and the installation is relatively convenient.
[0020] When the buffer beam is hit at high speed, the arc spring piece of the buffer beam will be squeezed, and then the arc spring piece of the main beam will be squeezed. Since the arc spring piece of the buffer beam is installed between the two buffer beam sliders, and the arc spring piece of the main beam is installed between the two main beam sliders, when the two arc spring pieces of the buffer beam and the arc spring piece of the main beam are squeezed, their curvature will gradually decrease, and the slider will move along the corresponding limit slide groove to absorb and reduce the impact energy. The dual effect of the buffer spring and the buffer spring can effectively absorb and reduce most of the impact energy when the vehicle collides at high speed, preventing damage to the vehicle and personnel.
[0021] Furthermore, the top of the arc-shaped spring piece of the buffer beam and the arc-shaped spring piece of the main beam and the lower edge of the arc-shaped structure are both planar structures. The arc-shaped spring piece of the buffer beam is fixedly connected to the buffer beam slider at the plane of its lower edge, and the arc-shaped spring piece of the main beam is fixedly connected to the main beam slider at the plane of its lower edge.
[0022] The top of the arc structure of the arc spring piece of the buffer beam and the arc spring piece of the main beam is a flat structure, so that the contact area between the arc spring piece of the buffer beam and the arc spring piece of the main beam is relatively large, and the operation is relatively stable during the buffering process. The lower edge of the arc structure of the arc spring piece of the buffer beam and the arc spring piece of the main beam is a flat structure, which is convenient for connection with the corresponding slider. Optimally, the arc spring piece of the buffer beam and the arc spring piece of the main beam are made of metal materials, which is easy to manufacture. In addition, the arc spring piece of the buffer beam and the arc spring piece of the main beam have a certain strength and can undergo elastic deformation when the impact force reaches a certain level, effectively absorbing the impact energy.
[0023] Furthermore, the buffer beam is provided with a plurality of energy absorption holes 2, which further enhances the buffering energy absorption effect of the buffer beam. Furthermore, a reinforcing rib 5 is fixedly installed on the inner surface of the buffer beam along the extension direction, and the buffer beam limit slide groove is provided on the reinforcing rib, which not only enhances the strength of the buffer beam, but also facilitates the installation of the buffer beam arc spring.
[0024] Furthermore, a damper 12 is fixedly installed on the inner surface of the main beam, and a connecting plate 13 is fixedly installed on the end of the damper, which further forms a third level of buffering and energy absorption for the vehicle, thereby reducing damage to the vehicle and personnel.
[0025] In summary, the buffering automobile anti-collision beam proposed by the utility model has a simple structure and is easy to install. It can also reduce most of the impact energy when a vehicle collides at high speed through multiple shock-absorbing and energy-absorbing effects, thereby preventing damage to the vehicle and personnel.
[0026] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
