Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a tailgate buffer seat with automatically adjustable length. Background Technology

[0002] As an important component of the car tailgate system, the buffer pad's main function is to cushion the impact between the tailgate and the car body sheet metal, preventing paint peeling or even deformation caused by the impact. Currently, the buffer pads on vehicle tailgates mainly use threaded rubber pads or similar devices that adjust the height via threads. However, rubber pads are solid and dense rubber, with small compression and large rebound force. In addition, the height of the rubber pads needs to be manually adjusted. When the height is adjusted too high, the tailgate closing force is too large, and the opening noise is loud. When the height is adjusted too low, it cannot effectively support the tailgate, causing the tailgate to vibrate when closing and making abnormal noises when driving on bumpy roads. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a back door buffer seat with automatically adjustable length.

[0004] The automatically adjustable length rear door buffer seat provided by this utility model adopts the following technical solution:

[0005] An automatically adjustable length rear door cushion includes a cushioning pad, a base mounted on a telescopic assembly, the base being mounted on the rear door, and the telescopic assembly connecting the base and the cushioning pad.

[0006] Furthermore, the telescopic assembly includes a movable cylinder, a fixed cylinder, and a buffer spring. One end of the movable cylinder is connected to a buffer pad, and the other end is slidably inserted into the fixed cylinder. The buffer spring is located inside the fixed cylinder, and its two ends respectively abut against the end of the movable cylinder and the inner bottom of the fixed cylinder. The fixed cylinder is mounted on the base.

[0007] Furthermore, guide grooves are provided on both sides of the fixed cylinder along its own length direction, and guide blocks that slide in the guide grooves are provided on both sides of the end of the movable cylinder away from the buffer pad.

[0008] Furthermore, the base is provided with a guide rod (21) coaxial with the fixed cylinder, and the guide rod (21) passes through the bottom of the movable cylinder.

[0009] Furthermore, the base and the fixed cylinder are connected by threads.

[0010] Furthermore, the base 2 is provided with an installation groove for mounting the fixed cylinder 32, and the fixed cylinder 32 is threadedly connected to the groove wall of the installation groove.

[0011] Furthermore, the shrunk base is equipped with a buckle for connecting to the rear door.

[0012] In summary, this utility model has at least one of the following beneficial effects: the buffer pad is made of rubber, which has a good buffering effect; at the same time, the buffer pad is installed on the back door through a telescopic component, and the height of the buffer pad can be adjusted through the telescopic component.

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0018] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0019] This utility model discloses a back door buffer seat with automatically adjustable length. (See reference...) Figure 1-2 The automatically adjustable length rear door buffer seat includes a buffer pad 1, a base 2, and a telescopic component 3. The base 2 is installed on the rear door, and the telescopic component 3 connects the base 2 and the buffer pad 1. The buffer pad 1 is made of rubber and has a good buffering effect. At the same time, the buffer pad 1 is installed on the rear door through the telescopic component 3, and the height of the buffer pad 1 can be adjusted through the telescopic component 3.

[0020] In this embodiment, the telescopic component 3 includes a movable cylinder 31, a fixed cylinder 32, and a buffer spring 33. One end of the movable cylinder 31 is connected to the buffer pad 1, and the other end is slidably inserted into the fixed cylinder 32. The buffer spring 33 is located inside the fixed cylinder 32, and its two ends respectively abut against the end of the movable cylinder 31 and the inner bottom of the fixed cylinder 32. The fixed cylinder 32 is disposed on the base 2. When the back door squeezes the buffer pad 1, the movable cylinder 31 moves inside the fixed cylinder 32, compressing the buffer spring 33. The buffer spring 33 can play a supporting and buffering role, and can provide continuous rebound force support for the back door, thus having a better buffering effect.

[0021] In this embodiment, guide grooves 34 are provided on both sides of the fixed cylinder 32 along its length direction, and guide blocks 35 that slide within the guide grooves 34 are provided on both sides of the movable cylinder 31 away from the buffer pad 1. During the movement of the movable cylinder 31, the guide blocks 35 move within the guide grooves 34. At the same time, the guide grooves 34 do not penetrate the side wall of the fixed cylinder 32. Therefore, the guide grooves 34 can limit the guide blocks 35, preventing the limit blocks 35 from drawing out of the guide grooves 34, and thus limiting the movable cylinder 31.

[0022] In this embodiment, the base 2 is provided with a guide rod 21 coaxial with the fixed cylinder 32. The guide rod 21 passes through the bottom of the movable cylinder 31, and the bottom of the movable cylinder 31 is provided with a through hole through which the guide rod 21 can just pass, so that the movable cylinder 31 can move along the guide rod 21.

[0023] In this embodiment, the base 2 and the fixed cylinder 32 are connected by threads, which makes it convenient to install the fixed cylinder 32 on the base 2.

[0024] In this embodiment, the base 2 is provided with an installation groove for installing the fixed cylinder 32. The fixed cylinder 32 is threadedly connected to the groove wall of the installation groove. Rotating the fixed cylinder 32 can install the fixed cylinder 32 on the base 2 or remove it from the base 2, making installation and removal more convenient.

[0025] In this embodiment, the shrink base 2 is provided with a buckle 22 for connecting with the back door. The base 2 is snapped onto the back door by the buckle 22, so as to realize the quick-release installation of the base 2.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
