DETAILED DESCRIPTION
[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
[0015] like Figure 1-2 A bumper support connection structure shown in the figure comprises an arc-shaped buffer plate 1 located between the bumper and the front end of the vehicle body, the buffer plate 1 has the same arc as the inner wall of the bumper and matches the length, a reinforcing rib plate 2 is welded in the middle of the outer wall of the buffer plate 1 close to the front end of the vehicle body, a slide groove extending to both sides is opened in the middle of the reinforcing rib plate 2, a buffer member sliding along the long axis direction of the buffer plate 1 is embedded in the slide groove, a connecting member extending to the outside of the slide groove is fixed in the middle of the buffer member, the connecting member is connected to the front end of the vehicle body, and buffer auxiliary members connected to both ends of the buffer plate 1 are installed on both sides of the reinforcing rib plate 2;
[0016] A buffer rubber pad 3 is attached to the middle of the outer wall of the buffer plate 1 close to the bumper;
[0017] Furthermore, a plurality of screw holes 12 for installation are provided on the buffer plate 1. During installation, the buffer plate 1 is partially connected to the vehicle bumper using bolts and other tools, and the buffer plate 1 is placed on the inner side of the vehicle bumper so that the buffer rubber pad 3 on the front side of the buffer plate 1 fits against the inner wall of the bumper and supports the bumper. The buffer plate 1 is then connected to the front end of the vehicle body through a connecting piece to complete the support and connection of the bumper.
[0018] After installation, when the vehicle bumper collides and generates impact forces in different directions, the buffer plate 1 can utilize the buffer parts and buffer auxiliary parts that slide back and forth, and cooperate with the bumper to perform multi-directional buffering and energy release, thereby reducing damage to the front end of the vehicle body.
[0019] The slide groove includes an inner slide groove 4 and an outer slide groove 5, the inner slide groove 4 is located inside the reinforcing rib plate 2, the outer slide groove 5 is located on the surface of the reinforcing rib plate 2, the diameter of the inner slide groove 4 is greater than the diameter of the outer slide groove 5, and the inner slide groove 4 and the outer slide groove 5 are integrated;
[0020] The buffer member includes a slider 6 that matches the inner wall of the inner slide groove 4. The slider 6 slides along the direction of the inner slide groove 4. A first nitrogen spring 7 is connected to each end of the slider 6. The other end of the nitrogen spring is fixed to the end of the inner slide groove 4.
[0021] On the basis of the above, the movement of the slider 6 in the inner slide groove 4 is restricted by the first nitrogen springs 7 on both sides. When the bumper is hit by an external force and pushes the bumper to move, causing the buffer plate 1 to be partially displaced, since the buffer component and the buffer auxiliary component are connected to the front end of the vehicle body, the buffer component and the buffer auxiliary component will be partially displaced to buffer the impact force and release energy.
[0022] Furthermore, the reinforcing rib rod part can not only improve the overall strength of the buffer plate 1 , but also facilitate the connection and cooperation between the buffer component and the buffer auxiliary component and the buffer plate 1 .
[0023] The connecting member comprises a connecting block 8 fixed on the surface of the slider 6, the end of the connecting block 8 is movably hinged with a connecting plate 9, and the connecting plate 9 is connected to the front end of the vehicle body;
[0024] The buffer auxiliary component includes a second nitrogen spring 10 fixed at both ends of the reinforcing rib plate 2, the second nitrogen spring 10 is perpendicular to the surface of the reinforcing rib plate 2, a buffer spring 11 is installed at the end of the second nitrogen spring 10, and the other end of the buffer spring 11 is connected to the end of the buffer plate 1.
[0025] Furthermore, an opening is set on the connecting plate 9, and the connecting plate 9 is connected to the front end of the vehicle body using bolts or other workpieces, so that after the bumper is installed, the buffer plate 1 is partially located between the bumper and the front end of the vehicle body, forming a buffer energy release area to reduce the impact force received by the vehicle body during a collision.
[0026] On the basis of the above, when the bumper collides, the impact forces in multiple directions can be released through the buffer plate 1. The two ends of the buffer plate 1 are buffered and released by the second nitrogen spring 10 and the buffer spring 11, and the front and front forces will cause the buffer plate 1 and the bumper to shift. In this process, the buffer plate 1 part can change a certain angle through the movable hinged connecting plate 9 and the connecting block 8, and the slider 6 can squeeze the first nitrogen spring 7 in the inner slide groove 4 for displacement, so as to buffer and release the impact force and reduce the damage to the vehicle body caused by the impact force.
[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
