Description

Technical Field

[0001] The utility model belongs to the technical field of automobile machinery, in particular to an automobile machinery anti-collision buffer device. Background Art

[0002] With the continuous increase in car ownership, traffic accidents are becoming more frequent. In a vehicle collision, the impact force often causes serious damage to the vehicle and its occupants. Existing vehicle anti-collision devices mostly focus on strengthening the vehicle structure or providing in-vehicle protection measures such as airbags. However, there is still room for improvement in their ability to cushion and absorb energy during a collision.

[0003] For example, the patent with announcement number CN221938176U discloses an anti-collision buffer device for automobile machinery. When the buffer frame is subjected to external collision, the positioning column can be pushed downward, and the first spring is compressed at the same time to achieve the first buffering and anti-collision. The bearing capacity of the buffer frame can be enhanced by the reinforcing plate. Secondly, the arc plate can protect the left and right corners of the automobile machinery, and the elastic action of the third spring can further achieve the buffering effect, thereby achieving a buffering effect on the front and left and right corners of the automobile machinery, thereby achieving a comprehensive anti-collision and buffering effect.

[0004] However, the above structure is only cushioned by springs and cushions, and its structure is also a rigid structure, lacking an energy-absorbing structure. When the impact force is too large, the structure is easily deformed, resulting in damage to the cushioning structure and affecting the overall cushioning effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing anti-collision structure is relatively simple and is easily deformed when subjected to a large impact, thereby affecting the normal buffering function.

[0006] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a mechanical anti-collision buffer device for an automobile, comprising a support plate, a mounting plate provided on the support plate, and a connecting energy release mechanism and a guide buffer mechanism arranged on the support plate; the connecting energy release mechanism comprises a slide groove and a buffer block, the slide groove is arranged on the support plate, the top wall of the slide groove is penetrated by a movable groove, a slider is provided for sliding in the slide groove, the slider is connected to the guide buffer mechanism, a connecting plate is fixed on the slider, a push plate is provided at the end of the connecting plate, and the buffer block is connected to both ends of the support plate.

[0007] Furthermore, an energy release cavity is provided in the connected buffer connection block, an energy release box is provided in the energy release cavity, and the push plate is movably plugged into the energy release cavity.

[0008] Furthermore, sleeves are provided at both ends of the support plate, plug-in blocks are provided on the side walls at both ends of the support plate, and the buffer blocks are plugged into the sleeves.

[0009] Furthermore, the guide buffer mechanism includes a guide rod and an anti-collision plate. The guide rod is movable and passes through both ends of the support plate. A limit block is provided at the bottom end of the guide rod. The anti-collision plate is connected to the top end of the two groups of guide rods. A spring is provided between the anti-collision plate and the support plate. The spring is sleeved on the guide rod. A damper is connected between the support plate and the anti-collision plate. The damper is symmetrically provided in multiple groups.

[0010] Preferably, a push rod is hinged on the slider, and the push rod passes through the movable slot and is hinged to the anti-collision plate.

[0011] Preferably, a buffer plate is provided on the anti-collision plate, and the material of the buffer plate is rubber.

[0012] Preferably, air holes are provided on the side walls of the energy release chamber.

[0013] The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides an automobile mechanical anti-collision buffer device, which, by setting an energy release chamber and an energy release box, can transmit the impact to the connecting plate and the push plate through the push rod and the slider when the anti-collision plate is impacted, and utilizes the push plate to extrude the energy release box, and effectively absorbs and dissipates a large amount of collision energy through the deformation, extrusion and fracture of the energy release box itself, avoiding the device directly bearing the impact and causing structural deformation, and cooperates with the damper and spring to further improve the anti-collision buffer effect, and through the replaceable structure of the buffer block, the device can be replaced and reused when it is not deformed.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-4As shown, the utility model proposes an automobile mechanical anti-collision buffer device, including a support plate 1, a mounting plate 2 is provided on the support plate 1, and also includes a connection energy release mechanism 3 and a guide buffer mechanism 4 provided on the support plate 1; the connection energy release mechanism 3 includes a slide 5 and a buffer block 6, the slide 5 is provided on the support plate 1, the top wall of the slide 5 is penetrated by a movable groove 7, a slider 8 is provided for sliding in the slide 5, the slider 8 is connected to the guide buffer mechanism 4, a connecting plate 9 is fixed on the slider 8, and a push plate 10 is provided at the end of the connecting plate 9, the buffer block 6 is connected to both ends of the support plate 1, and an energy release cavity 11 is provided in the connected buffer block 6, which releases energy. There are air holes 22 on the side wall of the cavity 11, and an energy release box 12 is provided in the energy release cavity 11. The push plate 10 is movably inserted in the energy release cavity 11. When the guide buffer mechanism 4 is impacted, the slider 8 is driven to move by the connection, pushing the connecting plate 9 and the push plate 10. The push plate 10 extends into the energy release cavity 11 and squeezes the energy release box 12. The energy release box 12 is composed of a plurality of honeycomb-shaped aluminum energy absorption boxes nested in each other. When the energy absorption box is squeezed and collided by the push plate 10, it can effectively absorb and dissipate a large amount of collision energy through its own deformation, extrusion and fracture, thereby reducing the impact transmitted to the mounting plate 2 and the vehicle machinery.

[0022] like Figure 1 and 3 As shown, sleeves 13 are provided at both ends of the support plate 1, and plug blocks 14 are provided on the side walls of both ends of the support plate 1. The buffer block 6 is inserted into the sleeve 13. The buffer block 6 is inserted into the sleeve 13 and limited by the plug blocks 14 and connected by bolts. This can facilitate the disassembly, assembly and replacement of the buffer block 6 and can be reused when the device structure is not deformed or damaged.

[0023] like Figure 1 and 2 As shown, the guide buffer mechanism 4 includes a guide rod 15 and an anti-collision plate 16. The guide rod 15 is movable through the two ends of the support plate 1. A limit block 17 is provided at the bottom end of the guide rod 15. The anti-collision plate 16 is connected to the top of the two groups of guide rods 15. A buffer plate 21 is provided on the anti-collision plate 16. The buffer plate 21 is made of rubber. A push rod 20 is hinged on the slider 8. The push rod 20 passes through the movable slot 7 and is hinged to the anti-collision plate 16. A spring 18 is provided between the anti-collision plate 16 and the support plate 1. The spring 18 is sleeved on the guide rod 15. A damper 19 is connected between the support plate 1 and the anti-collision plate 16. The damper 19 is symmetrically arranged in multiple groups. When the anti-collision plate 16 is impacted, it drives the guide rod 15 to move, and at the same time squeezes the spring 18 and the damper 19. The spring 18 and the damper 19 can reduce part of the impact. When the anti-collision plate 16 moves, it drives the push rod 20 to move, and the push rod 20 is used to push the slider 8 to move, thereby releasing the impact, reducing the direct impact on the support plate 1, and preventing the support plate 1 from being deformed due to excessive force to a certain extent.

[0024] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
