Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts application technology, and in particular to a socket-type automotive rear bumper shock absorber. Background Technology
[0002] The rear bumper is an important safety component at the rear of a vehicle. In the event of a collision, the rear bumper can absorb and disperse the impact energy, thereby reducing injury to the rear structure of the vehicle and the occupants.
[0003] Currently, most automotive rear bumper shock absorbers on the market are installed using adhesive or bolt fixing methods. Adhesive methods suffer from weak adhesion and are prone to detachment after prolonged use or under significant external impact. Bolt fixing is cumbersome, requiring drilling holes in the rear bumper, which not only damages the original structure of the bumper but also increases installation costs and time. Furthermore, existing shock absorber pads are integrated units, resulting in limited shock absorption and failing to fully meet the cushioning needs of vehicles in complex collision situations. Therefore, this utility model proposes a socket-type automotive rear bumper shock absorber pad. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a sleeve-type automotive rear bumper shock absorber. By sleeved on the end face of the shock absorber, and honeycomb holes are provided at the connection, the stability of the connection can be increased and the toughness during use can be improved by utilizing the characteristics of hexagonal honeycomb holes. A buffer is provided at the connection between the shock absorber and the sleeve, so that when the sleeve is subjected to external impact, it can transfer part of the impact force to the buffer, thereby absorbing the external impact force in conjunction with the energy absorption of the honeycomb holes and improving the shock absorption effect.
[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a sleeve-type automotive rear bumper shock absorber pad is provided, including a shock absorber pad body, wherein a sleeve part is snapped into the top of the shock absorber pad body, and the bottom of the sleeve part extends into the interior of the shock absorber pad body.
[0006] A buffer element is fitted onto the outer wall of the sleeve near the main body of the shock-absorbing pad, and the buffer element is tightly fitted against the top of the main body of the shock-absorbing pad.
[0007] The present invention is further configured such that: the inner wall of the shock-absorbing pad body is evenly provided with multiple anti-slip grooves near the bottom position, and the inner wall of the multiple anti-slip grooves is arc-shaped.
[0008] The above technical solution facilitates the installation of the shock-absorbing pad body, and during the fitting and fixing process, the internal anti-slip grooves can be used to improve the connection between the shock-absorbing pad body and the rear bumper.
[0009] The present invention is further configured such that: the sleeve part includes a fixing block, the bottom of the fixing block is fixedly connected to a hollow connecting part, the connecting part is uniformly provided with a plurality of honeycomb holes in the circumferential direction, the top of the fixing block is fixedly connected to a first elastic part, the first elastic part is connected to a second elastic part, the center of the second elastic part is fixedly connected to a transmission part, and the top of the transmission part is fixedly connected to an impact part.
[0010] Through the above technical solution, the connecting part can fix the sleeve part to the shock-absorbing pad body, while the impact part can easily contact the external impact component, thus making it easy to receive the external impact force. The impact force is transmitted to the transmission part, the second elastic part and the first elastic part in sequence, and finally to the entire fixed block. At this time, the characteristics of the honeycomb holes are used to ensure the strength and a certain toughness when subjected to impact force.
[0011] The present invention is further configured such that: the connecting part extends to the connecting groove opened at the top of the shock-absorbing pad body, and is fixedly connected to the positioning block by engaging with the inner wall of the connecting groove through honeycomb holes.
[0012] The above technical solution facilitates the connection of the sleeve to the positioning block by using the honeycomb holes during installation, thereby stably installing the sleeve inside the shock-absorbing pad body and preventing it from falling off during use.
[0013] The present invention is further configured such that the connection between the first elastic part and the second elastic part is an arc-shaped elastic transition connection.
[0014] The above technical solution facilitates the transfer of force from the second connecting part to the first elastic part, and the force is weakened by the arc-shaped connection.
[0015] The present invention is further configured such that the bottom of the transmission part and the bottom of the second elastic part are provided in an arc-shaped elastic transition.
[0016] The above technical solution facilitates the transmission part to extend and compress into the sleeve part by utilizing the arc-shaped connection between it and the first elastic part when subjected to external impact, and weakens the force by utilizing the arc-shaped connection.
[0017] The present invention is further configured such that: the buffer component includes two collars, and multiple buffer parts are fixedly connected to the opposite surfaces of the two collars, and the multiple buffer parts are evenly distributed in a circumferential direction.
[0018] The above technical solution utilizes the collars at both ends to fit onto the connecting part, which can absorb the force generated by the compression of the connecting part.
[0019] The present invention is further configured such that the buffer parts are arranged in a cross configuration, and the cross connection is arc-shaped.
[0020] The above technical solution utilizes a cross-shaped arrangement, allowing the material to undergo plastic deformation through the cross space when subjected to compression, and thus absorb the impact force.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. The present invention proposes a sleeve-type automotive rear bumper shock absorber pad, which has a sleeve part sleeved on the end face of the shock absorber pad and honeycomb holes provided at the connection. By utilizing the characteristics of hexagonal honeycomb holes, the stability of the connection can be increased and the toughness during use can be improved.
[0023] 2. The present invention proposes a socket-type automotive rear bumper shock absorber pad, which provides a buffer at the connection between the shock absorber pad and the socket, so that when the socket is subjected to external impact, it can transfer part of the impact force to the buffer, thereby absorbing the external impact force in conjunction with the energy absorption of the honeycomb holes and improving the shock absorption effect.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0032] like Figures 1-4 As shown, a sleeve-type automotive rear bumper shock absorber includes a shock absorber body 1. The inner wall of the shock absorber body 1 is evenly provided with multiple anti-slip grooves 11 near the bottom. The inner walls of the multiple anti-slip grooves 11 are all arc-shaped, which facilitates the connection between the shock absorber body 1 and the rear bumper by utilizing the internal anti-slip grooves 11 when the shock absorber body 1 is installed and fixed.
[0033] like Figures 3-5 As shown, a sleeve part 2 is snapped onto the top of the shock-absorbing pad body 1, and the bottom of the sleeve part 2 extends into the interior of the shock-absorbing pad body 1. The sleeve part 2 includes a fixing block 21, and a hollow connecting part 22 is fixedly connected to the bottom of the fixing block 21. The connecting part 22 extends into a connecting groove 12 opened at the top of the shock-absorbing pad body 1, and a positioning block 13 is fixedly connected to the inner wall of the connecting groove 12 through honeycomb holes 23. This allows the sleeve part 2 to be snapped onto the positioning block 13 using the honeycomb holes 23 during installation, thus stably installing the sleeve part 2 inside the shock-absorbing pad body 1 and preventing it from falling off during use. The connecting part 22 has multiple honeycomb holes 23 evenly opened in the circumferential direction. A first elastic part 24 is fixedly connected to the top of the fixing block 21, and a second elastic part 25 is connected to the first elastic part 24. The connection between the first elastic part 24 and the second elastic part 25 is an arc-shaped elastic transition connection, which facilitates the second connecting part 25 to absorb the force. The force is transmitted to the first elastic part 24, and the force is weakened by the arc-shaped connection. The center of the second elastic part 25 is fixedly connected to the transmission part 26. The bottom of the transmission part 26 and the bottom of the second elastic part 25 are set in an arc-shaped elastic transition, so that when the transmission part 26 is subjected to external impact, it can extend and squeeze into the sleeve part 2 by the arc-shaped connection with the first elastic part 25, and weaken the force by the arc-shaped connection. The top of the transmission part 26 is fixedly connected to the impact part 27. The sleeve part 2 can be fixed to the shock-absorbing pad body 1 by the connection part 22, and the impact part 27 can easily contact the external impact member, so as to easily receive the external impact force. The impact force is transmitted to the transmission part 26, the second elastic part 25 and the first elastic part 24 in sequence, and finally to the entire fixed block 21. At this time, the characteristics of the honeycomb hole 23 are used to ensure strength and a certain toughness when subjected to impact force.
[0034] like Figure 3 and Figure 6As shown, a buffer member 3 is fitted onto the outer wall of the sleeve part 2 near the shock-absorbing pad body 1, and the buffer member 3 is tightly fitted against the top of the shock-absorbing pad body 1. The buffer member 3 includes two collars 31, and multiple buffer parts 32 are fixedly connected to the opposite surfaces of the two collars 31. The buffer parts 32 are arranged in a cross pattern, and the cross connection is arc-shaped. By using the cross arrangement, when subjected to compression, they can generate plastic deformation through the cross space and absorb the impact force. The multiple buffer parts 32 are evenly distributed in the circumferential direction. The collars 31 at both ends are fitted onto the connecting part 22, which can receive the force generated after the sleeve part 2 is compressed, thereby absorbing it.
