DETAILED DESCRIPTION
[0027] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application.
[0028] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, and are not limited to the number of objects, for example, the first object can be one or more.
[0029] It should be understood that "some embodiments" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.
[0030] The sliding door buffer structure and the vehicle provided by the present application will be described in detail below by listing specific embodiments.
[0031] With reference to Figures 1 to 4 The embodiment of the present application provides a sliding door buffer structure, which comprises a base 1, a buffer 2 and an adjusting mechanism. The base 1 is used for connecting with a vehicle body, the buffer 2 is used for buffering the acting force in the opening process of the sliding door, and the adjusting mechanism is connected with the base 1 and the buffer 2 respectively to adjust the position of the buffer 2 relative to the base 1.
[0032] Specifically, the sliding door buffer structure is suitable for a vehicle with a sliding door, such as some MPV (Multi-Purpose Vehicle) or commercial vehicle, etc. The door of this type of vehicle is opened or closed in a sliding form, that is, a sliding door. Compared with a rotating door, the sliding door can greatly reduce the space size required when the door is opened, improve the stress state of the vehicle body, and facilitate the entry and exit of passengers. Specifically, the sliding door is provided with an upper guide rail and a lower guide rail on both sides, and a sliding block is arranged in the upper guide rail and the lower guide rail respectively. The sliding door is connected with the sliding block, and the opening or closing of the sliding door is realized by the sliding of the sliding block in the upper guide rail and the lower guide rail. The sliding door buffer structure of the embodiment of the utility model is arranged at the end of the upper guide rail and the lower guide rail, and is used for contacting the sliding block during the opening of the sliding door, thereby buffering the sliding block, so as to realize the buffering of force during the opening of the sliding door.
[0033] The sliding door buffer structure of the embodiment of the utility model comprises a base 1, a buffer piece 2 and an adjusting mechanism. The base 1 can be processed from a hard material such as metal or alloy, has good strength and rigidity, and is used for being connected with the vehicle body, as shown in the drawing. Figures 1 to 3 The side of the base 1 away from the buffer piece 2 is provided with a connecting piece 11 which protrudes from the surface of the base 1. The connecting piece 11 can be arranged in the connecting hole of the vehicle body, so as to realize the fixed connection of the base 1 and the vehicle body. In some embodiments, the bottom of the connecting piece 11 can be provided with a barb structure, so as to realize the limiting effect after the connecting piece 11 is arranged in the connecting hole of the vehicle body, thereby avoiding the disconnection of the connecting piece 11, and ensuring the connection reliability of the base 1 and the vehicle body. The buffer piece 2 can be processed from a material with elastic deformation capacity such as silica gel or rubber. The buffer piece 2 is used for abutting against the sliding block in the upper guide rail and the lower guide rail during the opening of the sliding door, so as to realize the buffering of force during the opening of the sliding door.
[0034] The adjusting mechanism is movably connected with the base 1 and the buffer piece 2 respectively. The adjusting mechanism can adjust the position of the buffer piece 2 relative to the base 1, so as to realize the change of the position of the buffer piece 2. In some embodiments, the adjusting mechanism can be a telescopic rod. One end of the adjusting mechanism is fixedly connected with the base 1, and the other end is fixedly connected with the buffer piece 2. The adjusting mechanism makes the buffer piece 2 move relative to the base 1 through the telescopic movement of the adjusting mechanism, so as to realize the change of the position of the buffer piece 2. In some embodiments, the adjusting mechanism can be a sliding piece arranged on the base 1. The buffer piece 2 is fixedly connected with the sliding piece. The sliding piece slides relative to the base 1 to drive the movement of the buffer piece 2, so as to realize the change of the position of the buffer piece 2. In some embodiments, the adjusting mechanism can be a connecting rod mechanism. The connecting rod mechanism is hingedly connected with the base 1 and the buffer piece 2 respectively. Under the action of the connecting rod mechanism, the buffer piece 2 can move relative to the base 1, so as to realize the change of the position of the buffer piece 2. Of course, the adjusting mechanism can also have other structural forms, and the embodiment of the utility model does not make any limitation in this regard.
[0035] In practical applications, under the influence of machining errors and motion errors, the sliding blocks of some sliding doors may not collide with the buffer structures at the ends of the upper and lower guide rails at the same time, resulting in a gap between one of the sliding blocks and the buffer structure. Under the influence of the gap, the sliding door is prone to shaking in the fully open state, affecting the driving experience of passengers. In the prior art, the buffer structures at the ends of the upper and lower guide rails are mostly fixed structures, and the positions of the buffer structures cannot be adjusted, so that the gap between the sliding blocks and the buffer structures cannot be improved, and it is difficult to meet the functional requirements of the sliding door anti-shaking. However, in the buffer structure of the sliding door buffer structure in the embodiments of the present application, the buffer piece 2 can move relative to the base 1 through the adjusting mechanism to adjust the position of the buffer piece 2. If the buffer structure and the sliding block in the lower guide rail are in full contact in the fully open state of the sliding door, and there is a 3mm error between the buffer structure and the sliding block in the upper guide rail, the sliding door buffer structure of the present application can be arranged at the end of the upper guide rail. The buffer piece 2 is adjusted to move 3mm relative to the base 1 through the adjusting mechanism to compensate for the gap between the sliding block in the upper guide rail and the buffer structure, so that the sliding block is in full contact with the buffer piece 2, thereby ensuring that the sliding blocks in the upper and lower guide rails can fully contact the buffer structure at the end of the guide rail, so that the buffer structure can effectively limit and buffer, thereby preventing the sliding door from shaking in the fully open state and improving the driving experience of passengers.
[0036] It should be noted that if there is a gap between the buffer structure and the sliding block in the upper guide rail in the fully open state of the sliding door, the buffer structure at the end of the upper guide rail can adopt the sliding door buffer structure in the embodiments of the present application. If there is a gap between the buffer structure and the sliding block in the lower guide rail in the fully open state of the sliding door, the buffer structure at the end of the lower guide rail can adopt the sliding door buffer structure in the embodiments of the present application. Of course, in some embodiments, the sliding door buffer structure in the embodiments of the present application can also be used at the ends of the upper and lower guide rails to improve the flexibility of the buffer structure. The position of the buffer piece 2 in the buffer structure can be reasonably adjusted according to the use of the sliding door to ensure that the sliding blocks in the upper and lower guide rails can fully contact the buffer piece 2 in the fully open state of the sliding door, effectively preventing the sliding door from shaking in the fully open state.
[0037] Optionally, with reference to Figures 1 to 4 , the adjusting mechanism is a connecting rod mechanism, the connecting rod mechanism comprises a main connecting rod 3 and a first auxiliary connecting rod 4; the main connecting rod 3 is arranged in a first direction and movably connected with the base 1; one end of the first auxiliary connecting rod 4 is hingedly connected with the main connecting rod 3, and the other end is hingedly connected with the buffer piece 2; the main connecting rod 3 moves relative to the base 1 in the first direction to drive the first auxiliary connecting rod 4 to rotate relative to the main connecting rod 3, and the first auxiliary connecting rod 4 drives the buffer piece 2 to move in a second direction in the process of rotating relative to the main connecting rod 3, wherein the second direction is perpendicular to the first direction.
[0038] Specifically, the first direction is as shown by the X direction in Figures 1 to 4 , the second direction is as shown by the Y direction in Figures 1 to 4 , the second direction Y is perpendicular to the first direction X, wherein the "perpendicular" in the embodiment of the utility model includes not only the absolute perpendicular case, but also the approximately perpendicular case in the general cognition, such as the state that the included angle between the first direction X and the second direction Y is 89°-91°, which is regarded as the state that the first direction X and the second direction Y are perpendicular to each other. The main connecting rod 3 is arranged along the first direction X and is movably connected with the base 1, and the movable connection mode includes but is not limited to rotary connection, sliding connection, clearance fit and the like, and the specific connection mode is not limited in the embodiment of the utility model. One end of the first auxiliary connecting rod 4 is hinged with the main connecting rod 3, and the other end is hinged with the buffer 2, that is, the first auxiliary connecting rod 4 can rotate relative to the main connecting rod 3 and can also rotate relative to the buffer 2. In actual application, personnel can adjust the movement of the main connecting rod 3 along the first direction X relative to the base 1, and in the process that the main connecting rod 3 moves along the first direction X relative to the base 1, the first auxiliary connecting rod 4 will be driven to rotate relative to the main connecting rod 3, and in the process that the first auxiliary connecting rod 4 rotates relative to the main connecting rod 3, the buffer 2 will be driven to move along the second direction Y, so as to convert the movement of the main connecting rod 3 along the first direction X into the movement of the buffer 2 along the second direction Y, and realize the adjustment of the position of the buffer 2.
[0039] In the embodiment of the utility model, the adjusting mechanism adopts a connecting rod mechanism, and through the hinged relationship between the main connecting rod 3 and the first auxiliary connecting rod 4, the movement of the main connecting rod 3 along the first direction X can be converted into the movement of the buffer 2 along the second direction Y, so as to realize the adjustment of the position of the buffer 2. Since the upper guide rail and the lower guide rail of the sliding door are arranged along the second direction Y, the direction of the impact force on the buffer 2 from the sliding block is also the second direction Y, and in this adjustment mode, the connecting rod mechanism helps to further relieve the impact force on the buffer 2, thereby improving the buffering capacity of the buffer 2. Through testing, in this adjustment mode, the buffer 2 can withstand an impact load of about 1KN in the fully open state of the sliding door, which meets the use requirements of the sliding door on most vehicles. At the same time, this adjustment mode helps to save the size of the upper guide rail and the lower guide rail along the second direction Y, that is, to save the space in the length direction of the vehicle, thereby being beneficial to the optimization and improvement of the vehicle.
[0040] Optionally, referring to Figure 1 and Figure 2 , the first auxiliary connecting rod 4 includes a first connecting rod 41 and a second connecting rod 42; the first connecting rod 41, the second connecting rod 42 and the main connecting rod 3 constitute a triangular structure.
[0041] Specifically, one end of the first link rod 41 and the second link rod 42 is hinged with the main link rod 3, and the other end is hinged with the buffer 2, one of the first link rod 41 and the second link rod 42 cannot produce the movement in the first direction X between the main link rod 3, and the other can produce the movement in the first direction X between the main link rod 3. For example, in the embodiment, the second link rod 42 is arranged between the main link rod 3 and cannot produce the movement in the first direction X, and the first link rod 41 can produce the movement in the first direction X between the main link rod 3, so that in the process of the main link rod 3 moving in the first direction X, the buffer 2 moves in the second direction Y under the driving of the second link rod 42, and the first link rod 41 rotates relative to the main link rod 3 and moves in the first direction X relative to the main link rod 3, so as to ensure that the link rod mechanism can work normally. Wherein, the second link rod 42 can be hinged with the end of the main link rod 3, so as to save the size of the main link rod 3 in the first direction X.
[0042] The first link rod 41, the second link rod 42 and the main link rod 3 form a triangular structure, and in the process of the first link rod 41 and the second link rod 42 moving relative to the main link rod 3, the first link rod 41 and the second link rod 42 are always in a triangular structure with the main link rod 3, thereby helping to improve the stability of the movement process of the link rod mechanism and the stability in the adjustment process of the buffer 2.
[0043] Optionally, referring to Figures 1 to 4 , the link rod mechanism further comprises a second auxiliary link rod 5; one end of the second auxiliary link rod 5 is hinged with the main link rod 3, and the other end is hinged with the base 1; the main link rod 3 moves relative to the base 1 in the first direction to drive the second auxiliary link rod 5 to rotate relative to the main link rod 3.
[0044] Specifically, on the basis of the first auxiliary link rod 4 being hinged with the main link rod 3, the link rod mechanism further comprises a second auxiliary link rod 5, one end of the second auxiliary link rod 5 is hinged with the main link rod 3, and the other end is hinged with the base 1, that is, the second auxiliary link rod 5 can rotate relative to the main link rod 3 and also can rotate relative to the base 1. In the process of the personnel adjusting the main link rod 3 moving in the first direction X relative to the base 1, the main link rod 3 will drive the second auxiliary link rod 5 to rotate relative to the main link rod 3, and the process of the second auxiliary link rod 5 rotating relative to the main link rod 3 will change the position of the main link rod 3 relative to the base 1, thereby realizing the adjustment of the position of the main link rod 3. As shown in Figure 1 and Figure 2 , under the action of the second auxiliary link rod 5, the main link rod 3 will move in the second direction Y, thereby driving the first auxiliary link rod 4 and the buffer 2 to move in the second direction Y, expanding the adjustment range of the link rod mechanism, so as to realize the larger range adjustment of the buffer 2 in the limited space, thereby helping to improve the adjustment efficiency of the sliding door buffer structure.
[0045] Optionally, referring to Figure 1 andFigure 2 The second sub-connecting rod 5 comprises a third connecting rod 51 and a fourth connecting rod 52; the third connecting rod 51, the fourth connecting rod 52 and the main connecting rod 3 form a triangular structure.

Among them, the fourth connecting rod 52 can be hinged to the end of the main connecting rod 3 to save the size of the main connecting rod 3 along the first direction X. Similarly, the third connecting rod 51, the fourth connecting rod 52 and the main connecting rod 3 also form a triangular structure, and the third connecting rod 51 and the fourth connecting rod 52 always form a triangular structure with the main connecting rod 3 during the movement of the third connecting rod 51 and the fourth connecting rod 52 relative to the main connecting rod 3, thereby helping to improve the stability of the connecting rod mechanism during movement and the stability of the buffer 2 during adjustment.
[0047] Optionally, referring to Figure 1 and Figure 2 , the connecting rod mechanism further comprises a fixing member; the fixing member is fixedly connected with the main connecting rod 3, and the first sub-connecting rod 4 and the second sub-connecting rod 5 are respectively hinged to the fixing member.
