Description

Technical Field

[0001] This application relates to the field of vehicle cushioning technology, specifically to a cushioning mechanism and a vehicle. Background Technology

[0002] Buffer mechanisms serve to reduce vibration, improve the sound quality of modal door opening and closing, and protect surrounding components. They are commonly installed in the engine compartment, trunk, and door opening mechanisms of automobiles. Fixed buffer mechanisms are the most common type, but their buffer height is not adjustable. Because the dimensions of various body parts vary within a certain range during actual automobile production, fixed buffer mechanisms may not match the surrounding components or meet design requirements after installation, thus affecting the vehicle's performance. Utility Model Content

[0003] In view of the above, it is necessary to provide a buffer mechanism and vehicle that can adjust the buffer height.

[0004] In a first aspect, embodiments of this application provide a buffer mechanism, comprising: a mounting base including a plurality of abutments, the plurality of abutments being spaced apart and surrounding to form a receiving groove; an adjusting member movably disposed within the receiving groove, one end of the adjusting member extending out of the receiving groove; a buffer member disposed at the end of the adjusting member extending out of the receiving groove; and a locking member movably sleeved on the outer periphery of the plurality of abutments, the locking member having a flexible pressing portion and a pushing portion that flexibly abut against the outer wall of the adjusting member, the pushing portion being disposed on the side of the flexible pressing portion away from the buffer member, and a guide slope being provided at the end of the abutment near the buffer member, the pushing portion abutting against the guide slope.

[0005] During installation, the aforementioned buffer mechanism is first placed in the receiving groove, with the end of the adjusting member extending out of the receiving groove at its maximum distance from the mounting base. Then, the locking member is fitted onto the outer periphery of the supporting body, and the flexible pressing part flexibly presses against the outer wall of the adjusting member, keeping it stationary. At this time, the pushing part does not press against the guide slope. Next, the mounting base is secured to the vehicle's load-bearing component, causing the vehicle's moving component to move towards the mounting base. The moving component pushes against the buffer, causing the adjusting member to move within the receiving groove and press the buffer at the desired height. Then, the moving component is moved away from the mounting base to reset its position. Finally, the locking member moves away from the buffer, the pushing part presses against the guide slope, and the end of the supporting body near the buffer moves towards the adjusting member, causing the end of the supporting body near the buffer to press against the adjusting member, thus locking the adjusting member to the mounting base.

[0006] By setting multiple spaced abutments, sufficient space is provided for the abutment to move near the buffer. The adjustable and movable component effectively addresses dimensional deviations in various vehicle body parts during actual production, allowing for adjustment of the buffer height based on installation requirements, thus adapting to vehicles with different buffer height needs. A flexible pressing part, utilizing the elastic deformation properties of flexible materials, tightly conforms to the outer wall of the adjusting component, preventing loosening. A guide slope at the abutment's end near the buffer allows for engagement with the pushing part; as the pushing part slides along the guide slope, its movement is converted into movement of the abutment towards the adjusting component, thereby securing the adjusting component firmly.

[0007] In one possible implementation, the locking member has a first internal thread, which is located on the side of the pushing part away from the flexible pressing part. The outer side wall of the plurality of supporting bodies has a first external thread that mates with the first internal thread, and the first external thread and the first internal thread are connected.

[0008] In one possible implementation, the outer side wall of the adjusting member is provided with a second external thread, and the inner side wall of the plurality of abutments is provided with a second internal thread that mates with the second external thread, and the second internal thread and the second external thread are connected.

[0009] In one possible implementation, the mounting base further includes a retaining portion, the outer wall of which is provided with retaining bodies; one end of each retaining body is connected to the retaining portion.

[0010] In one possible implementation, the mounting base further includes a guide portion disposed within the receiving groove and connected to the retaining portion, one end of the guide portion extending into the adjusting member.

[0011] In one possible implementation, the mounting base further includes a stop portion connected to the outer periphery of the retaining portion and disposed between the retaining body and the receiving portion.

[0012] In one possible implementation, the mounting base further includes an adhesive-coated structure that covers the outer periphery of the stop portion.

[0013] In one possible implementation, the mounting base further includes a seal connected to the stop and disposed between the stop and the retaining body.

[0014] In one possible implementation, the end of the adjusting member extending out of the mounting base has a protrusion structure, and the buffer member has a groove adapted to the protrusion structure, the groove being sleeved on the outer periphery of the protrusion structure; or the end of the adjusting member extending out of the mounting base has a groove, and the buffer member has a protrusion structure adapted to the groove, the groove being sleeved on the outer periphery of the protrusion structure.

[0015] Secondly, embodiments of this application provide a vehicle, including: a load-bearing component; a movable component disposed on one side of the load-bearing component; and the aforementioned buffer mechanism, wherein the mounting seat is held in place by the load-bearing component.

[0016] The vehicle of this application includes the aforementioned buffer mechanism. During installation, the adjusting member is first placed in the receiving groove, with the distance between the end of the adjusting member extending out of the receiving groove and the mounting seat being at its maximum. Then, the locking member is sleeved on the outer periphery of the abutment body, and the flexible pressing part flexibly presses against the outer wall of the adjusting member, keeping the adjusting member stationary, while the pushing part does not abut against the guide slope. Next, the mounting seat is clamped onto the vehicle's load-bearing component, causing the vehicle's moving component to move toward the mounting seat. The moving component pushes against the buffer member, thereby moving the adjusting member within the receiving groove and pressing the buffer member to the required height. Then, the moving component is moved away from the mounting seat, resetting the moving component. Finally, the locking member moves away from the buffer member, the pushing part abuts against the guide slope, and the end of the abutment body near the buffer member moves toward the adjusting member, thereby locking the adjusting member to the mounting seat.

[0017] By setting multiple spaced abutments, sufficient space is provided for the abutment to move near the buffer. The adjustable and movable component effectively addresses dimensional deviations in various vehicle body parts during actual production, allowing for adjustment of the buffer height based on installation requirements, thus adapting to vehicles with different buffer height needs. A flexible pressing part, utilizing the elastic deformation properties of flexible materials, tightly conforms to the outer wall of the adjusting component, preventing loosening. A guide slope at the abutment's end near the buffer allows for engagement with the pushing part; as the pushing part slides along the guide slope, its movement is converted into movement of the abutment towards the adjusting component, thereby securing the adjusting component firmly.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1This application provides a buffer mechanism 100 for providing cushioning between a load-bearing component (not shown) and a moving component (not shown) of a vehicle (not shown). In this embodiment, the load-bearing component is the vehicle body, and the moving component is the vehicle cover. It is understood that in other embodiments, the mounting base 10 can be secured to the vehicle cover. It is also understood that in other embodiments, the buffer mechanism 100 can be applied to other mechanical devices. Specifically, the buffer mechanism 100 includes a mounting base 10, an adjusting member 20, a buffer member 30, and a locking member 40.

[0028] Please see Figure 2 , Figure 3 and Figure 5 The mounting base 10 includes multiple abutment bodies 121, which are spaced apart and surround to form a receiving groove 122. An adjusting member 20 is movably disposed within the receiving groove 122, with one end of the adjusting member 20 extending out of the mounting base 10. A buffer member 30 is disposed at the end of the adjusting member 20 extending out of the mounting base 10. A locking member 40 is movably sleeved on the outer periphery of the multiple abutment bodies 121. The locking member 40 has a flexible pressing part 44 and a pushing part 42 that flexibly abut against the outer wall of the adjusting member 20. The pushing part 42 is disposed on the side of the flexible pressing part 44 facing away from the buffer member 30. A guide slope 1211 is provided at the end of the abutment body 121 near the buffer member 30, and the pushing part 42 abuts against the guide slope 1211. The adjusting member 20 can be slidably disposed within the mounting base 10 or rotatably disposed within the mounting base 10.

[0029] In this embodiment, during installation of the buffer mechanism 100, the adjusting member 20 is first placed in the receiving groove 122, with the distance between the end of the adjusting member 20 extending out of the receiving groove 122 and the mounting base 10 at its maximum. Then, the locking member 40 is fitted onto the outer periphery of the supporting body 121, and the flexible pressing part 44 flexibly presses against the outer wall of the adjusting member 20, keeping the adjusting member 20 stationary. At this time, the pushing part 42 does not abut against the guide slope 1211. Next, the mounting base 10 is secured to the vehicle's load-bearing component, causing the vehicle's moving component to move towards the mounting base 10. The moving part pushes the buffer 30 to move, thereby moving the adjusting part 20 within the receiving groove and pressing the buffer 30 to the required height. Then, the moving part moves away from the mounting base 10 to reset the moving part. Finally, the locking part 40 moves away from the buffer 30, and the pushing part 42 abuts against the guide slope 1211 and moves the end of the holding body 121 near the buffer 30 toward the adjusting part 20, thereby locking the adjusting part 20 to the mounting base 10.

[0030] By setting multiple spaced abutments 121, sufficient space can be provided for the abutment 121 to move near the buffer 30. By setting a movable and height-adjustable adjusting member 20, the deviation in the dimensions of various parts of the car body in actual production can be effectively addressed. The buffer height of the buffer 30 can be adjusted according to the actual installation situation to adapt to vehicles with different buffer height requirements. By setting a flexible pressing part 44, the flexible pressing part 44 can fit tightly against the outer wall of the adjusting member 20 using the elastic deformation characteristics of the flexible material, preventing the adjusting member 20 from loosening. By setting a guide slope 1211 at the end of the abutment 121 near the buffer 30, it can cooperate with the pushing part 42. When the pushing part 42 slides along the guide slope 1211, it can convert its own movement into the movement of the abutment 121 towards the adjusting member 20, thereby making the abutment 121 abut against the adjusting member 20 and achieving a firm lock on the adjusting member 20.

[0031] Existing adjustable buffer mechanisms can adjust their height to a suitable position to ensure good vehicle appearance and performance when there are certain deviations in the dimensions of environmental components (various parts of the vehicle body). During vehicle assembly, it is necessary to ensure that the buffer part has zero or minimal contact with the environmental components. Excessive contact can cause deformation or difficulty in closing of the door or hood, while no contact will cause the buffer energy absorption function to fail. Existing adjustable buffer mechanisms can be manually adjusted in height after assembly to achieve the designed matching state. However, because the conditions of different vehicles are different, the amount of adjustment required varies. A single vehicle may require multiple adjustments to achieve a proper match, or errors may occur during adjustment, resulting in a discrepancy between the actual height and the required height. This makes installation cumbersome, inefficient, and time-consuming.

[0032] In this embodiment, the buffer mechanism 100 is installed by moving the moving part toward the mounting base 10. The moving part pushes the buffer 30 to move, thereby moving the adjusting part 20 within the mounting base 10. This adjusts the height of the end of the adjusting part 20 extending out of the mounting base 10 relative to the mounting base 10. In other words, during installation, after the moving part presses the buffer 30 to the required buffer height, the adjusting part 20 is locked to the mounting base 10 simply by the locking part 40. This reduces the number of adjustments, simplifies the operation, and makes installation quick and efficient.

[0033] In one possible implementation, the locking member 40 is provided with a first internal thread 411, which is located on the side of the pushing part 42 away from the flexible pressing part 44. The outer side wall of the plurality of supporting bodies 121 is provided with a first external thread 1212 that mates with the first internal thread 411. The first external thread 1212 and the first internal thread 411 are connected.

[0034] In this embodiment, the locking member 40 is provided with a sleeve hole 41 that is sleeved on the outer periphery of a plurality of supporting bodies 121. The flexible pressing part 44, the pushing part 42 and the first internal thread 411 are all provided on the hole wall of the sleeve hole 41. The flexible pressing part 44 is a rubber ring and the pushing part 42 is a protrusion-shaped structure.

[0035] In this embodiment, the first internal thread 411 inside the locking member 40 and the first external thread 1212 on the outer side wall of the supporting body 121 cooperate with each other to form a threaded connection structure. By rotating the locking member 40, the locking member 40 can be controlled to move along the supporting body 121 using the thread transmission principle, so that the pushing part 42 gradually pushes against the guide slope 1211, thereby realizing the supporting body 121's support and locking of the adjusting member 20; and the self-locking characteristic of the threaded connection can ensure that the adjusting member 20 is always in a stable locked state.

[0036] During installation, the adjusting element 20 is in the position Figure 4 In the state where the adjusting member 20 extends out of the mounting base 10, first, the retaining body 111 is held in the retaining hole of the bearing member, then the moving member is moved toward the mounting base 10, and the moving member pushes against the buffer member 30 to move, thereby moving the adjusting member 20 within the mounting base 10 until the buffer member 30 is pressed to the required height, then the moving member is moved away from the mounting base 10 to reset the moving member, and finally the locking member 40 locks the adjusting member 20 to the mounting base 10.

[0037] In one possible implementation, the outer periphery of the locking member 40 is provided with a plurality of parallel first anti-slip grooves 43, each first anti-slip groove 43 extending along the axis of the locking member 40, so that the locking member 40 can be easily rotated manually to move the locking member 40 along the support body 121.

[0038] In one possible implementation, the outer side wall of the adjusting member 20 is provided with a second external thread 21, and the inner side wall of the plurality of abutments 121 is provided with a second internal thread 1213 that mates with the second external thread 21, and the second internal thread 1213 is connected to the second external thread 21.

[0039] In this embodiment, the second external thread 21 on the outer side wall of the adjusting member 20 and the second internal thread 1213 on the inner side wall of the supporting body 121 cooperate with each other to form a threaded connection structure. When the adjusting member 20 rotates, the height of the adjusting member 20 extending out of the mounting base 10 can be adjusted conveniently and quickly by utilizing the thread transmission principle; and the self-locking characteristic of the threaded connection can ensure that the adjusted height remains stable.

[0040] During installation, after the locking member 40 locks the adjusting member 20 to the mounting base 10, the adjusting member 20 can also be rotated to a certain angle to change its height along the thread direction, so that the buffer member 30 can be moved to the required height to obtain the corresponding matching (gap or interference) state.

[0041] In one possible implementation, the mounting base 10 further includes a retaining portion 11, the outer side wall of which is provided with retaining bodies 111; one end of each abutment 121 is connected to the retaining portion 11.

[0042] In this embodiment, by holding the holding body 111 of the holding part 11 to the bearing component, the mounting base 10 can be securely held to the bearing component, ensuring the installation reliability of the buffer mechanism 100.

[0043] In this embodiment, the holding part 11 further includes a fixing body 112, which is generally a cuboid structure. In other embodiments, the fixing body 112 may also be a columnar structure, but is not limited thereto. The holding body 111 is generally a sheet-like structure. There are multiple holding bodies 111, which are evenly distributed around the periphery of the fixing body 112. An opening 1121 is provided on the outer wall of the fixing body 112. The holding body 111 is disposed in the opening 1121. One end of the holding body 111 is fixedly connected to the holding part 11, and the other end of the holding body 111 protrudes from the outer wall of the holding body 111 and can move into the opening 1121 to be held in the bearing component.

[0044] In this embodiment, the mounting base 10 further includes a receiving portion 12, which is composed of a plurality of supporting bodies 121. The supporting bodies 121 are generally sheet-like structures and are arranged in a ring.

[0045] In one possible implementation, the mounting base 10 further includes a guide portion 13, which is disposed within the receiving groove 122 and connected to the holding portion 11, with one end of the guide portion 13 extending into the adjusting member 20. Specifically, the guide portion 13 has a columnar structure, such as a pin, and is located in the middle of the receiving groove 122.

[0046] In this embodiment, the guide part 13 is connected to the holding part 11 and is disposed in the receiving groove 122, and one end of it extends into the adjusting member 20. It can provide precise guidance for the movement of the adjusting member 20, ensuring that the adjusting member 20 moves smoothly and steadily relative to the mounting base 10 along the predetermined direction, thereby improving the accuracy of height adjustment.

[0047] In one possible implementation, the mounting base 10 further includes a stop portion 14, which is connected to the outer periphery of the holding portion 11 and is disposed between the holding body 111 and the receiving portion 12, for blocking the locking member 40. Specifically, the stop portion 14 has an annular structure.

[0048] In this embodiment, the stop part 14 is disposed between the retaining body 111 and the receiving part 12, which can accurately limit and stop the locking member 40 and prevent the locking member 40 from moving excessively.

[0049] In one possible implementation, the mounting base 10 further includes an adhesive-coated structure 15 that covers the outer periphery of the stop portion 14. Specifically, the adhesive-coated structure 15 is annular and made of a flexible material, such as silicone.

[0050] In this embodiment, the rubber-coated structure 15 on the outer periphery of the stop portion 14 can press against the bearing component and cover the retaining hole, which can effectively prevent dust, moisture, foreign objects and the like from entering the bearing component through the retaining hole.

[0051] In one possible implementation, the mounting base 10 further includes a seal 16, which is connected to the stop portion 14 and disposed between the stop portion 14 and the retaining body 111. Specifically, the seal 16 is an annular sealing foam.

[0052] In this embodiment, the sealing member 16 is connected between the stop part 14 and the retaining body 111, and can be pressed against the retaining hole to ensure the sealing of the retaining hole and further prevent dust, moisture, foreign objects and the like from entering the bearing component.

[0053] In one possible implementation, the end of the adjusting member 20 extending out of the mounting base 10 is provided with a protruding structure 22, and the buffer member 30 is provided with a groove 31 adapted to the protruding structure 22, the groove 31 being sleeved on the outer periphery of the protruding structure 22.

[0054] Specifically, there are multiple raised structures 22, and these raised structures 22 can be different. The raised structure 22 can be an annular convex wall around the adjusting member 20, an annular flange connected to the end of the annular convex wall, or an annular convex ring connected to the end of the adjusting member 20. The buffer member 30 is made of silicone and has a cylindrical structure.

[0055] In this embodiment, the internal groove 31 of the buffer 30 can cover the multiple protrusions 22 of the adjusting member 20 to achieve the locking between the buffer 30 and the adjusting member 20.

[0056] In one possible implementation, the outer periphery of the buffer member 30 is provided with a plurality of parallel second anti-slip grooves 32, each of which extends along the axis of the buffer member 30. This allows the buffer member 30 to be rotated easily, thereby causing the adjusting member 20 to rotate.

[0057] In one possible implementation, the end of the adjusting member 20 extending out of the mounting base 10 is provided with a groove 31, and the buffer member 30 is provided with a protruding structure 22 adapted to the groove 31, with the groove 31 sleeved on the outer periphery of the protruding structure 22. In this way, the groove 31 inside the adjusting member 20 can cover the multiple protruding structures 22 of the buffer member 30, realizing the locking between the buffer member 30 and the adjusting member 20.

[0058] An embodiment of this application provides a vehicle (not shown), including a load-bearing component, a movable component, and a buffer mechanism 100. The movable component is located on one side of the load-bearing component, and a mounting seat 10 is held in place by the load-bearing component. The vehicle can be a gasoline-powered car, an electric car, a tram, etc., the load-bearing component can be the vehicle body, and the movable component can be a vehicle cover.
