[0036] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0038] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0039] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0040] like Figure 1 and Figure 2 As shown, this application embodiment provides a buffer 1, which can be applied to a vehicle. The buffer 1 is installed on the object to be installed on the vehicle, such as a tailgate trim panel 2 or a coat rack 3. By installing the buffer 1 on the tailgate trim panel 2 and / or the coat rack 3, the tailgate trim panel 2 and the coat rack 3 can make contact through the buffer 1. The buffer 1 includes a first main body 11, a second main body 12, and a connecting part 13. The first main body 11 and at least one second main body 12 are connected by the connecting part 13. At least a portion of the first main body 11 is capable of elastic deformation. A limiting recess 14 is provided between the first main body 11 and the second main body 12. The limiting recess 14 is recessed along the length direction X and / or the width direction Y of the buffer 1. During installation, the tailgate trim panel 2 or the coat rack 3 can extend into the limiting recess 14 so that the buffer 1 can engage with the tailgate trim panel 2 or the coat rack 3. The first main body 11 is provided with a flange 15 at one end near the limiting recess 14. The flange 15 is inclined in the direction of approaching the limiting recess 14, and the flange 15 can elastically deform in the direction of approaching or moving away from the limiting recess 14.

[0041] During installation, the buffer 1 engages with the object to be installed via the limiting recess 14. At this time, the flange 15 abuts against the object to be installed and deforms in a direction away from the limiting recess 14. The deformation of the flange 15 generates a restoring force, causing the flange 15 to tend to move closer to the limiting recess 14, so that the second main body 12 can cooperate with the flange 15 to clamp the object to be installed located in the limiting recess 14, thereby increasing the stability of the connection between the buffer 1 and the object to be installed.

[0042] By incorporating buffer 1, a cushioning and shock-absorbing function can be achieved, thereby reducing the possibility of the object to be installed shaking or generating noise. It also reduces the possibility of damage caused by bumps or knocks.

[0043] like Figure 3 As shown, in one possible implementation, the flange 15 is disposed along the circumference of the first main body portion 11.

[0044] This design allows the buffer 1 to contact the object to be installed along the circumference of the first main body 11 via the flange 15, thereby increasing the contact area between the buffer 1 and the object. This improves the stability of the buffer 1 installation and better meets practical usage requirements. Simultaneously, when the buffer 1 tilts, the deformation of the flanges 15 on different sides differs, resulting in different restoring forces. The flange 15 on the side of the tilt exhibits greater deformation and a larger restoring force, while the flange 15 on the other side exhibits less deformation and a smaller restoring force. Therefore, the different forces on different sides of the buffer 1 allow the restoring force to move the buffer 1 in the opposite direction of the tilt, returning it to its original position. This design improves the installation accuracy of the buffer 1 and better meets practical usage requirements.

[0045] In one possible implementation, the flange 15 forms an angle with the height direction Z of the buffer member 1, the angle being 20° to 30°. The angle between the flange 15 and the height direction Z of the buffer member 1 can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, etc. The flange 15 can be inclined outwards.

[0046] When the angle between the flange 15 and the height direction Z of the buffer 1 is less than 20°, the tilt angle of the flange 15 is too small, making it difficult to deform during use, which increases installation difficulty and affects installation efficiency. When the angle between the flange 15 and the height direction Z of the buffer 1 is greater than 30°, the tilt angle of the flange 15 is too large, resulting in a smaller deformation of the flange 15 during installation, a smaller restoring force, and a poor effect of the flange 15 on improving the installation stability of the buffer 1. Therefore, the tilt angle of the flange 15 can be between 20° and 30° to facilitate the installation of the buffer 1 while also improving the installation stability of the buffer 1.

[0047] In one possible implementation, the flange 15 has a size of 1 mm to 3 mm along the length direction X or width direction Y of the buffer member 1. The size of the flange 15 can be 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, etc.

[0048] When the flange 15 is less than 1 mm, its size is too small and has little effect on improving the installation stability of the buffer 1. When the flange 15 is greater than 3 mm, its size is too large, which will increase the volume of the buffer 1, occupy more space, and increase costs. Therefore, the size of the flange 15 can be between 1 mm and 3 mm.

[0049] In one possible implementation, the flange 15 can be 1 mm to 3 mm in size along the height direction Z of the buffer 1.

[0050] When the flange 15 is less than 1 mm, its size is too small and has little effect on improving the installation stability of the buffer 1. When the flange 15 is greater than 3 mm, its size is too large, which will increase the volume of the buffer 1, occupy more space, and increase costs. Therefore, the size of the flange 15 can be between 1 mm and 3 mm.

[0051] In one possible implementation, the flange 15 can be a ring structure, forming an approximate funnel-shaped structure, that is, the cross-sectional area of ​​the area enclosed by the flange 15 gradually increases along the direction away from the first main body 11.

[0052] like Figure 1 As shown, in one possible implementation, the end of the first main body 11 away from the limiting recess 14 is provided with an arc-shaped surface. In use, the arc-shaped surface is used to contact other components.

[0053] By providing an arc-shaped surface to the first main body 11, it is easier for the first main body 11 to contact other components. At the same time, compared with a flat surface, the arc-shaped surface can better transmit forces when in contact with other components, so that the arc-shaped surface is stressed as a whole. This helps to improve the structural strength of the first main body 11, reduce the possibility of deformation or damage to the first main body 11 during use, and better meet the actual use requirements.

[0054] like Figure 3 As shown, in one possible implementation, the first main body 11 includes a cavity, that is, the first main body 11 can be a hollow structure.

[0055] This design allows the first main body 11 to deform, thereby improving its shock absorption and buffering effect and better meeting actual usage requirements.

[0056] like Figure 1 As shown, in one possible implementation, the cross-sectional area of ​​the second main body portion 12 gradually decreases along the direction away from the limiting recess 14.

[0057] During installation, the second main body 12 can serve as a guide, allowing it to pass through the mounting hole 21 of the object to be installed. It deforms during the process of passing through the mounting hole 21 and returns to its original shape when it passes through the mounting hole 21.

[0058] This design allows at least a portion of the second main body 12 to be tapered, forming a guiding structure during installation. This guides the second main body 12 as it passes through the mounting hole 21. Blind installation is possible, reducing the difficulty of installing the buffer 1 and improving installation efficiency.

[0059] like Figure 2 As shown, in one possible embodiment, the second main body portion 12 includes a first body portion 121 and a second body portion 122 connected to each other. The first body portion 121 is located at the end of the second body portion 122 away from the limiting recess 14 and extends along the height direction Z of the buffer member 1. The cross-sectional area of ​​the second body portion 122 gradually decreases along the direction away from the limiting recess 14, that is, along the direction close to the first body portion 121, the cross-sectional area of ​​the second body portion 122 gradually decreases, and the second body portion 122 is used to form a tapered structure. The cross-sectional area of ​​the first body portion 121 is not greater than the cross-sectional area of ​​the second body portion 122 at the end close to the first body portion 121.

[0060] During installation, the first body part 121 can be used as a pulling part. The first body part 121 first passes through the mounting hole 21 of the object to be installed. The operator can pull the buffer 1 from the other side of the object to be installed through the first body part 121 so that the second body part 122 can pass through the mounting hole 21 and install the buffer 1 in place.

[0061] The first body part 121 can be used as a pulling part to facilitate the operator to install the buffer 1, which helps to reduce the installation difficulty of the buffer 1 and better meets the actual use needs.

[0062] like Figure 3 As shown, in one possible implementation, the buffer 1 may include at least two second main body portions 12. Each second main body portion 12 is arranged sequentially along the length direction X or the width direction Y of the buffer 1.

[0063] During installation, each of the second main body parts 12 can pass through the corresponding mounting hole 21.

[0064] In one possible implementation, the number of mounting holes 21 may correspond to the number of second body portions 12.

[0065] By setting at least two second main body parts 12, the stability of the buffer 1 during installation can be improved, and the possibility of the buffer 1 rotating around its own height direction Z can be reduced, which is more in line with actual usage requirements.

[0066] Based on the buffer 1 involved in the above embodiments, this application also provides a vehicle. The vehicle may include the buffer 1 involved in any of the above embodiments. Since the buffer 1 has the above technical effects, the vehicle including the buffer 1 also has the corresponding technical effects, which will not be repeated here.

[0067] like Figure 4 and Figure 5 As shown, in one possible implementation, the vehicle may include a tailgate trim panel 2 and a coat rack 3. The tailgate trim panel 2 and / or coat rack 3 are provided with mounting holes 21, through which the buffer 1 can be mounted to the tailgate trim panel 2 or the coat rack 3. When the buffer 1 is mounted on the tailgate trim panel 2, the first main body portion 11 and the second main body portion 12 are located on opposite sides of the tailgate trim panel 2, the connecting portion 13 is located in the mounting hole 21, the tailgate trim panel 2 can extend into the limiting recess 14, the flange 15 abuts against the tailgate trim panel 2 and is in a deformed state, and the first main body portion 11 is used to abut against the coat rack 3. Along the direction closer to the second main body portion 12, the cross-sectional area of ​​the mounting hole 21 gradually decreases.

[0068] When the buffer 1 is installed on the coat rack 3, the first main body 11 and the second main body 12 are located on opposite sides of the coat rack 3, the connecting part 13 is located in the mounting hole 21, the coat rack 3 can extend into the limiting recess 14, the flange 15 abuts against the coat rack 3 and is in a deformed state, and the first main body 11 is used to abut against the tailgate trim panel 2. Along the direction close to the second main body 12, the cross-sectional area of ​​the mounting hole 21 gradually decreases.

[0069] The second main body 12 can extend into the mounting hole 21 along the end with the larger cross-sectional area and extend out from the end with the smaller cross-sectional area. This design allows the mounting hole 21 to have a guiding function, reducing the installation difficulty of the buffer 1.

[0070] By setting a buffer 1 on the tailgate panel and / or coat rack 3, the coat rack 3 and the tailgate panel 2 can contact each other through the buffer 1. When the coat rack 3 and the tailgate panel 2 move relative to each other, the buffer 1 can play a role in buffering and shock absorption, thereby reducing the possibility of collision between the coat rack 3 and the tailgate panel 2, which may cause damage or noise. This is beneficial to improving the user experience and is more in line with actual usage needs.

[0071] The material of buffer 1 can be TPO or similar materials. TPO has good elastic deformation ability and wear resistance, which is more in line with actual use requirements.

[0072] like Figure 2 As shown, taking the example of the buffer 1 being installed on the tailgate trim panel 2, the buffer 1 can interfere with the coat rack 3. Figure 2 To illustrate the interference between the buffer 1 and the coat rack 3 (the deformed structure of the buffer 1 is not shown), the interference size can range from 3 mm to 8 mm, allowing the buffer 1 to undergo elastic deformation. The interference size can be 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm, etc.
