[0021] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.
[0022] See also Figure 1-Figure 3 In order to solve the problems in the prior art, the present invention provides a rear anti-collision beam assembly structure 1 for an automobile. The rear anti-collision beam assembly structure 1 includes an anti-collision beam body 11 and a connecting sleeve assembly 12. The connecting sleeve assembly 12 includes a sleeve 121, a flange plate 122, a fixing plate 123, a buffer cylinder 124, a buffer spring 125 and a buffer plate 126. One end of the sleeve 121 is fixedly connected to the side of the anti-collision beam body 11 for plug-in connection with the automobile longitudinal beam. The flange plate 122 is located at the other end of the sleeve 121 and is spot-welded to the sleeve 121. The fixed plate 123 is located between the anti-collision beam body 11 and the flange plate 122 and is fixedly connected to the sleeve 121. The buffer cylinder 124 is installed on the side of the fixed plate 123 close to the flange plate 122. After the buffer cylinder 124 is extended, a buffer gap is formed between the flange plate 122. The buffer plate 126 and the buffer spring 125 are both located inside the sleeve 121. A baffle 1211 is fixed on the side of the sleeve 121 close to the anti-collision beam body 11. The two ends of the buffer spring 125 are respectively held between the buffer plate 126 and the baffle 1211.
[0023] By fixing the sleeve 121 on the anti-collision beam body 11 and arranging a buffer spring 125 in the sleeve 121, when the rear anti-collision beam assembly structure 1 is installed on the car, the longitudinal beam on the car is plugged into the sleeve 121, and the buffer spring 125 abuts against the buffer plate 126 so that the buffer plate 126 abuts against the end of the longitudinal beam, and then the rear anti-collision beam assembly structure 1 is squeezed to make the flange plate 122 fit on the tail plate of the car, and the flange plate 122 is fixedly connected to the tail plate of the car by bolts. , thereby realizing the installation of the rear anti-collision beam assembly structure 1 at the rear of the automobile. Since the flange plate 122 and the sleeve 121 are connected by spot welding, when a minor rear-end collision occurs, the rear anti-collision beam assembly structure 1 can be slightly displaced relative to the longitudinal beam under the support of the buffer spring 125 on the longitudinal beam, so as to absorb the impact force of the rear vehicle on the automobile, thereby reducing the damage to the rear vehicle and avoiding the rigid contact between the rear vehicle and the rear anti-collision beam assembly structure 1 of the automobile, thereby aggravating the damage to the rear vehicle.
[0024] By fixing the fixing plate 123 on the sleeve 121 between the flange plate 122 and the anti-collision beam body 11, and arranging a buffer oil cylinder 124 between the flange plate 122 and the fixing plate 123, when a major rear-end collision occurs in the automobile, the anti-collision beam body 11 is subjected to a major impact, so that the spot welding between the flange plate 122 and the sleeve 121 is desoldered, and the sleeve 121 and the flange plate 122 can slide relative to each other, that is, the anti-collision beam body 11 drives the sleeve 121 to move under the action of the collision, and the flange plate 122 is fixed on the automobile tailboard and positioned The position remains unchanged, so that the spot welding between the flange plate 122 and the sleeve 121 is de-soldered, and then part of the impact force is absorbed when the flange plate 122 and the sleeve 121 are de-soldered. When the sleeve 121 is displaced, it drives the fixed plate 123 and the buffer cylinder 124 to displace synchronously. When the buffer cylinder 124 contacts the flange plate 122, the buffer cylinder 124 retracts and absorbs the impact force again, so as to further reduce the damage to the rear vehicle and avoid the rigid contact between the rear vehicle and the rear anti-collision beam assembly structure 1 of the automobile, which aggravates the damage to the rear vehicle.
[0025] Compared with the rear anti-collision beam in the prior art, the rear anti-collision beam assembly structure 1 of the utility model can cause the anti-collision beam body 11 to be slightly displaced under the action of the buffer spring 125 in the event of a minor vehicle rear-end collision, so that the buffer spring 125 absorbs the impact force during the rear-end collision and reduces the damage to the rear vehicle. In the event of a major vehicle rear-end collision, the sleeve 121 and the flange plate 122 are de-soldered, and the anti-collision beam body 11 drives the fixed plate 123 and the buffer cylinder 124 to be displaced synchronously, and the buffer cylinder 124 retracts when the buffer cylinder 124 contacts the flange plate 122 to absorb part of the impact force under the action of the buffer cylinder 124. At the same time, the buffer spring 125 is compressed when the anti-collision beam body 11 is displaced to absorb part of the impact force under the action of the buffer spring 125, thereby reducing the damage to the rear vehicle and reducing the injury rate of people and vehicles in rear-end collision accidents.
[0026] In an embodiment of the present utility model, a socket is provided in the middle of the flange plate 122 for plugging into the sleeve 121, and welding points fixedly connected to the sleeve 121 are formed around the socket. The flange plate 122 is fixed to the sleeve 121 through the welding points. When the anti-collision beam body 11 is impacted, the flange plate 122 can be desoldered from the sleeve 121, so that the flange plate 122 and the sleeve 121 can be desoldered under different impact forces on the anti-collision beam body 11, so as to avoid excessive impact force causing increased damage to the vehicle behind.
[0027] In an embodiment of the present utility model, a protruding slide rail 111 is provided on the side of the anti-collision beam body 11, and a slide groove 1212 is provided at the end of the sleeve 121 away from the flange plate 122. The sleeve 121 is slidably connected to the slide rail 111 through the slide groove 1212, so that the rear anti-collision beam assembly structure 1 can be installed on cars of different widths by adjusting the position of the sleeve 121 on the slide rail 111, thereby improving the adaptability of the rear anti-collision beam assembly structure 1, and there is no need to develop rear anti-collision beam assembly structures of different sizes for each model.
[0028] In an embodiment of the present utility model, the connecting sleeve assembly 12 also includes a positioning bolt 127, and the upper and lower surfaces of the slide rail 111 are arranged with positioning holes 1111 in an array. The positioning bolts 127 pass through the upper and lower sides of the sleeve 121 respectively and are held in the positioning holes 1111. When the rear anti-collision beam assembly structure 1 is installed on different vehicle models, the position of the sleeve 121 on the slide rail 111 is adjusted according to the vehicle model, and the positioning bolts 127 pass through the sleeve 121 and are held against the positioning holes 1111 to keep the position of the sleeve 121 on the slide rail 111 fixed, so that the rear anti-collision beam assembly structure 1 can be installed on the corresponding vehicle model, thereby improving the installation adaptability of the rear anti-collision beam assembly structure 1 on different vehicle models.
[0029] In an embodiment of the present utility model, a rib plate 128 is provided on the surface of the fixing plate 123 away from the flange plate 122, and the two right-angled sides of the rib plate 128 are respectively fixed on the fixing plate 123 and the sleeve 121, so as to strengthen the connection firmness between the fixing plate 123 and the sleeve 121 under the action of the rib plate 128. Therefore, in a major rear-end collision, the fixing plate 123 can provide support for the buffer cylinder 124 under the action of the rib plate 128, and absorb the impact force under the action of the buffer cylinder 124, thereby reducing the damage to the rear vehicle.
[0030] In an embodiment of the present invention, an array of ribs 128 are arranged around the sleeve 121 and fixedly connected to the fixing plate 123, so as to provide support for multiple directions of the fixing plate 123 under the action of multiple ribs 128, thereby further strengthening the connection firmness between the fixing plate 123 and the sleeve 121.
[0031] In an embodiment of the present invention, an array of buffer cylinders 124 is arranged around the sleeve 121 and fixedly connected to the fixed plate 123, so that in the event of a major rear-end collision, multiple buffer cylinders 124 will simultaneously abut against the flange plate 122 and retract at the same time, thereby further enhancing the absorption effect of the impact force under the action of multiple buffer cylinders 124 and reducing the damage to the rear vehicle.
[0032] In an embodiment of the present invention, a buffer pad is provided on one side of the flange plate 122 close to the buffer cylinder 124 to absorb the impact force under the flexible contact between the buffer pad plate and the buffer cylinder 124, thereby avoiding the deformation of the flange plate 122 caused by the rigid contact between the flange plate 122 and the buffer cylinder 124.
[0033] In an embodiment of the present invention, the sleeve 121 includes any one of a round sleeve 121 and a square sleeve 121 to adapt to longitudinal beams of different shapes, thereby enabling the rear anti-collision beam assembly structure 1 to be installed on vehicles with longitudinal beams of different shapes.
