Technical Field
[0001] This application relates to the field of vehicle component technology, and in particular to a buffer assembly, a door system, and a vehicle. Background Technology
[0002] In vehicle door systems, buffer components are typically used to cushion the doors. For example, a pair of buffer blocks are placed at the gooseneck hinge of the trunk lid to ensure that the trunk lid stops smoothly at the top and to prevent the lid from opening too wide.
[0003] Different car models have different door opening inertia, which also affects the stiffness curve requirements of the buffer components. Currently, the stiffness curve of the buffer components is difficult to adjust flexibly, and buffer components with different stiffness curves need to be developed separately for different car models, which is costly.

[0005] To address the aforementioned issues, this application provides a buffer assembly applied to a vehicle door system. The vehicle door system includes a support portion and a door. The buffer assembly is disposed between the support portion and the door. The buffer assembly includes a main body portion, a buffer portion, and a blocking portion. The main body portion forms an accommodating space and has an opening connecting the accommodating space and the outside. The buffer portion is disposed within the accommodating space and is elastic. The blocking portion is disposed at the opening and is connected to the main body portion to seal the opening.
[0006] In some embodiments, the main body is formed with a groove surrounding the opening, the radial dimension of the blocking portion is larger than the radial dimension of the opening, and the blocking portion is engaged in the groove.
[0007] In some embodiments, the support portion is provided with a mounting hole, and the shielding portion is provided with a snap-fit portion on the side opposite to the buffer portion, the snap-fit portion being used to snap into the mounting hole.
[0008] In some embodiments, the snap-fit portion is formed with a relief groove recessed toward the blocking portion, the sidewall of the snap-fit portion is configured to deform toward the relief groove under the pressure of the mounting hole, and a receiving groove surrounding the relief groove is formed on the outer periphery of the snap-fit portion. When the snap-fit portion is engaged in the mounting hole, the bottom wall of the receiving groove abuts against the mounting hole.
[0009] In some embodiments, the radial dimension of the end of the body portion away from the opening is smaller than that of the end of the body portion facing the opening.
[0010] In some embodiments, the radial dimension of the main body increases in the opening direction of the opening.
[0011] In some embodiments, the side wall of the main body is provided with a vent that connects the accommodating space to the outside.
[0012] In some embodiments, there are two vent holes, which are arranged at a distance from each other.

[0014] To address the aforementioned problems, this application provides a vehicle that includes the aforementioned door system.
[0015] Compared with existing technologies, the buffer assembly provided in this application is applied to a vehicle door system. The vehicle door system includes a support and a door.

The main body forms an accommodating space and has an opening connecting the accommodating space to the outside. The buffer part is disposed within the accommodating space and is elastic. The blocking part is disposed at the opening and is connected to the main body to seal the opening. Through the above implementation, the blocking part cooperates with the main body to allow the buffer part to be disposed within the accommodating space, thereby facilitating the buffer part to provide elasticity and stiffness to the entire buffer assembly, thus achieving buffering between the door and the support. Therefore, without changing the main body and the blocking part, the overall elasticity and stiffness of the buffer assembly can be adjusted simply by replacing the buffer parts with different elasticities and stiffnesses.

[0035] In vehicle door systems, buffer components are typically used to cushion the doors. For example, a pair of buffer blocks are placed at the gooseneck hinge of the trunk lid to ensure that the trunk lid stops smoothly at the top and to prevent the lid from opening too wide.
[0036] Different car models have different door opening inertia, which also affects the stiffness curve requirements of the buffer components. Currently, the stiffness curve of the buffer components is difficult to adjust flexibly, and buffer components with different stiffness curves need to be developed separately for different car models, which is costly.
[0037] This application provides a vehicle, please refer to... Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle according to one or more embodiments of this application.
[0038] Vehicle 1 includes a door system 2. Vehicle 1 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Vehicle 1 can be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. Vehicle 1 is equipped with a door system 2, which provides protection for vehicle 1 and separates the interior space of vehicle 1 from the outside world.
[0039] Combination Figure 2 , Figure 2 This is a schematic diagram of the structure of a door system according to one or more embodiments of this application.
[0040] To address the aforementioned issues, this application provides a vehicle door system 2, which includes a support 3, a door 4, and a buffer assembly 5, with the buffer assembly 5 disposed between the support 3 and the door 4. The door 4 separates the interior space of the vehicle 1 from the outside world. For example, the door 4 can be the trunk lid of the vehicle 1. The door 4 can be opened or closed; when closed, the door 4 separates the interior space of the trunk from the outside world. The support 3 provides support for the door 4 and, in conjunction with the door 4, forms the interior space of the vehicle 1. It is understood that the door 4 will collide with the support 3 during opening and closing. The buffer assembly 5, located between the door 4 and the support 3, provides cushioning between them, reducing the risk of damage to the door 4 and the support 3, and improving the stability of the vehicle door system 2.
[0041] Combination Figures 2-7 As shown, Figure 3 This is a first structural schematic diagram of a buffer component according to one or more embodiments of this application; Figure 4 This is a second structural schematic diagram of a buffer assembly according to one or more embodiments of this application; Figure 5 It is based on Figure 4 The diagram shows a cross-sectional view of the buffer assembly along the AA direction; Figure 6 This is a first exploded schematic diagram of a buffer component according to one or more embodiments of this application; Figure 7 This is a second exploded view of a buffer assembly according to one or more embodiments of this application; Figure 8 This is a first structural schematic diagram of the shielding portion and the snap-fit portion of a buffer assembly according to one or more embodiments of this application; Figure 9 This is a second structural schematic diagram of the shielding portion and the snap-fit portion of the buffer assembly according to one or more embodiments of this application.
[0042] To address the aforementioned issues, this application provides a buffer assembly 5 applied to a vehicle door system 2. The vehicle door system 2 includes a support portion 3 and a door 4. The buffer assembly 5 is disposed between the support portion 3 and the door 4. The buffer assembly 5 includes a main body portion 10, a buffer portion 20, and a blocking portion 30. The main body portion 10 forms an accommodating space 11 and has an opening 12 connecting the accommodating space 11 to the outside. The buffer portion 20 is disposed within the accommodating space 11 and is elastic. The blocking portion 30 is disposed at the opening 12 and is connected to the main body portion 10 to block the opening 12.
[0043] The main body 10 forms an accommodating space 11, providing support and protection for the buffer part 20. The main body 10 may have a certain rigidity, thus cooperating with the buffer part 20 to provide rigidity for the buffer assembly 5. The main body 10 may be elastic, and its material may include, but is not limited to, EPDM (ethylene propylene diene monomer rubber). The buffer part 20 is elastic, thereby allowing the buffer assembly 5 to better provide cushioning between the support part 3 and the door 4. The material of the buffer part 20 may include, but is not limited to, rubber. It is understood that buffer parts 20 with different stiffness curves can provide different stiffness curves for the buffer assembly 5. The overall stiffness curve of the buffer assembly 5 can be adjusted by replacing buffer parts 20 with different stiffness curves. The buffer part 20 can be of any shape; for example, it can be spherical, cylindrical, square, etc. It should be noted that by changing the shape of the buffer part 20, the stiffness curve of the buffer assembly 5 can also be changed, thereby allowing the buffer assembly 5 to match the cushioning requirements of different models of door systems 2. The main body 10 and the buffer part 20 are separately arranged. It is worth noting that, compared with the prior art, which develops independent integrated buffer blocks for different models of door systems 2, this application can flexibly adjust the stiffness curve of the buffer assembly 5 by only replacing the buffer part 20. The structure is simple and cost-effective. The blocking part 30 is provided at the opening 12 of the main body 10, thereby cooperating with the main body 10 to restrict the buffer part 20 in the accommodating space 11, improving the stability of the buffer part 20. The blocking part 30 can be provided inside or outside the accommodating space 11. For example, the blocking part 30 can be locked inside the accommodating space 11 to block the opening 12, or covered outside the accommodating space 11 to block the opening 12.
[0044] Through the above-described embodiments, the shielding part 30, in conjunction with the main body part 10, allows the buffer part 20 to be disposed within the accommodating space 11. This facilitates the buffer part 20 in providing elasticity and rigidity to the buffer assembly 5 as a whole, thereby achieving buffering between the door 4 and the support part 3. Thus, without replacing the main body part 10 and the shielding part 30, the overall elasticity and rigidity of the buffer assembly 5 can be adjusted simply by replacing the buffer part 20 with different elasticity and rigidity. This improves the flexibility and applicability of the stiffness curve of the buffer assembly 5, eliminating the need to develop different buffer assemblies 5 for different models of door 4. The structure is simple and cost-effective.
[0045] In some embodiments, the main body 10 has a groove 13 surrounding the opening 12, and the radial dimension of the blocking portion 30 is larger than the radial dimension of the opening 12, and the blocking portion 30 is engaged in the groove 13. Exemplarily, an annular groove 13 may be formed around the opening 12 in the circumferential direction. The radial dimension of the annular groove 13 matches the radial dimension of the blocking portion 30, and the radial dimension of the blocking portion 30 is larger than the radial dimension of the opening 12, thereby facilitating the engagement of the blocking portion 30 in the groove 13, improving the connection stability between the blocking portion 30 and the main body 10, and reducing the risk of the buffer portion 20 dislodging from the receiving space 11.
[0046] In some embodiments, the radial dimension of the end of the main body 10 away from the opening 12 is smaller than that of the end of the main body 10 facing the opening 12. It is understood that the main body 10 can contact the door 4 through the end away from the opening 12 and the support 3 through the other end. The smaller radial dimension of the end of the main body 10 away from the opening 12 increases the contact area between the main body 10 and the support 3, thereby improving the connection stability between the buffer assembly 5 and the support 3.
[0047] In some embodiments, the radial dimension of the main body 10 increases gradually in the opening direction x1 of the opening 12. Specifically, the radial dimension of the main body 10 can gradually increase in the opening direction x1, thereby improving the structural strength of the main body 10 and enabling the buffer assembly 5 to better buffer between the support 3 and the door 4.
[0048] In some embodiments, the side wall of the main body 10 is provided with a vent 14 that connects the accommodating space 11 to the outside. It is understood that when the door 4 and the support 3 are pressing the buffer assembly 5, the main body 10 will be compressed to a certain extent, reducing the volume of the accommodating space 11. By providing the vent 14, it is convenient for gas exchange between the inside of the accommodating space 11 and the outside, thereby alleviating the risk that the gas inside the accommodating space 11 cannot be discharged, and that the air pressure inside the accommodating space 11 is too high when the main body 10 is compressed, which may weaken the buffering effect of the buffer assembly 5.
[0049] In some embodiments, there are two vent holes 14, which are arranged relatively spaced apart. It is understood that setting the number of vent holes 14 to two and arranging them relatively spaced apart further facilitates the exchange of gas within the accommodating space 11 with the outside, increases the speed at which gas is discharged from the accommodating space 11 during the compression of the main body 10, and increases the speed at which outside gas enters the accommodating space 11 to balance the air pressure inside and outside the accommodating space 11 during the recovery of the shape of the main body 10, thereby reducing the impact of air pressure changes inside the accommodating space 11 on the buffering effect.
[0050] In some embodiments, the support portion 3 is provided with a mounting hole 31, and the shielding portion 30 is provided with a snap-fit portion 40 on the side opposite to the buffer portion 20. The snap-fit portion 40 is used to snap into the mounting hole 31. The snap-fit portion 40 is connected to the shielding portion 30. In some applications, the snap-fit portion 40 and the shielding portion 30 are integrally formed. It can be understood that the snap-fit portion 40 can snap into the mounting hole 31 on the support portion 3, thereby facilitating the fixed connection between the buffer assembly 5 and the support portion 3 through the snap-fit portion 40, improving the connection stability between the buffer assembly 5 and the support portion 3, and thus improving the buffering effect of the buffer assembly 5 between the support portion 3 and the door 4.
[0051] In some embodiments, the snap-fit portion 40 is formed with a relief groove 41 recessed toward the blocking portion 30, and the sidewall of the snap-fit portion 40 is configured to deform toward the relief groove 41 under the pressure of the mounting hole 31. A receiving groove 42 surrounding the relief groove 41 is formed on the outer periphery of the snap-fit portion 40. When the snap-fit portion 40 is snapped into the mounting hole 31, the bottom wall of the receiving groove 42 abuts against the mounting hole 31. For example, during the process of engaging the snap-fit part 40 into the mounting hole 31, the snap-fit part 40 enters the mounting hole 31, and the radial dimension of part of the snap-fit part 40 is larger than the radial dimension of the mounting hole 31. The sidewall of the snap-fit part 40 deforms toward the relief groove 41 under the pressure of the mounting hole 31, thereby facilitating the snap-fit part 40 to pass through the mounting hole 31. During the passage process, when the receiving groove 42 corresponds to the mounting hole 31, the sidewall of the mounting hole 31 enters the receiving groove 42 and abuts against the bottom wall of the receiving groove 42, thereby facilitating the snap-fit part 40 to engage with the mounting hole 31. It should be noted that on the side of the receiving groove 42 away from the blocking part 30, the maximum radial dimension of the snap-fit part 40 can be set according to actual needs. For example, snap-fit parts 40 with different radial dimensions can be set according to the radial dimension of the mounting hole 31. With the main body 10 and the buffer part 20 unchanged, by replacing different snap-fit parts 40, the buffer assembly 5 can be adapted to different mounting holes 31, further improving the adaptability of the buffer assembly 5 and saving costs. Figures 7-8As shown, the maximum radial dimension of the snap-fit portion 40 can be either a first dimension D1 or a second dimension D2, where the second dimension D2 is larger than the first dimension D1. In scenarios where the snap-fit portion 40 and the shielding portion 30 are integrally formed, the snap-fit portion 40 and the shielding portion 30 can be replaced together. In some applications, the maximum radial dimension of the snap-fit portion 40 can be set to correspond one-to-one with the stiffness curve of the buffer portion 20. For example, a buffer portion 20 with a specific stiffness curve is set to correspond with a snap-fit portion 40 with a specific maximum radial dimension. This allows operators to understand the corresponding model and stiffness curve of the buffer assembly 5 simply by observing the radial dimension of the snap-fit portion 40, without having to directly observe the buffer portion 20, thus reducing the risk of installation errors.
[0052] In summary, the buffer assembly 5 provided in this application is applied to a door system 2. The door system 2 includes a support 3 and a door 4. The buffer assembly 5 is disposed between the support 3 and the door 4. The buffer assembly 5 includes a main body 10, a buffer part 20, and a blocking part 30. The main body 10 forms an accommodating space 11 and has an opening 12 that connects the accommodating space 11 to the outside. The buffer part 20 is disposed within the accommodating space 11 and is elastic. The blocking part 30 is disposed at the opening 12 and is connected to the main body 10 to block the opening 12. Through the above-described embodiments, the shielding part 30, in conjunction with the main body part 10, allows the buffer part 20 to be disposed within the accommodating space 11. This facilitates the buffer part 20 in providing elasticity and rigidity to the buffer assembly 5 as a whole, thereby achieving buffering between the door 4 and the support part 3. Thus, without replacing the main body part 10 and the shielding part 30, the overall elasticity and rigidity of the buffer assembly 5 can be adjusted simply by replacing the buffer part 20 with different elasticity and rigidity. This improves the flexibility and applicability of the stiffness curve of the buffer assembly 5, eliminating the need to develop different buffer assemblies 5 for different models of door 4. The structure is simple and cost-effective.
