It cannot meet the gap step adjustment in other areas or directions of the tailgate, and the adjustment is quite limited. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a vehicle that solves the technical problem in the prior art where the gap between the vehicle tailgate and the vehicle body can only be adjusted in the left-right direction, resulting in significant limitations in gap adjustment.

[0005] On the one hand, this application provides a vehicle tailgate limiting structure, which is disposed between the tailgate side panel and the vehicle body side panel. The vehicle tailgate limiting structure includes a first limiting component and a second limiting component.

[0006] The first limiting component has a first limiting end, which can switch between multiple adjustment positions along a first preset direction, the first preset direction being parallel to the direction from the first limiting component toward or away from the second limiting component; the first limiting component is used to be installed on the side panel of the rear door;

[0007] The second limiting component has a second limiting end, which can abut against the first limiting end when the vehicle tailgate is in a closed state; the second limiting component is used to be installed on the side of the vehicle body, and the second limiting component can move along a second preset direction, which is perpendicular to the first preset direction.

[0008] In one embodiment, the second limiting component can also move along a third preset direction, which is a direction toward or away from the first limiting component.

[0009] In one embodiment, the first limiting end is formed with a first limiting surface, which is gradually tapered in the direction toward the second limiting component; the second limiting end is formed with a second limiting surface, which is arranged around an axis parallel to the first preset direction to form a curved surface with an opening, and the first limiting surface can abut against the second limiting surface.

[0010] In one embodiment, the first limiting component includes a first mounting member and a first limiting member movably connected to the first mounting member. The first limiting member is threaded to the first mounting member about its own central axis, and the central axis of the first limiting member is parallel to the first preset direction. The first limiting end is formed at the end of the first limiting member opposite to the first mounting member. The first mounting member is used to connect to the back door side panel.

[0011] In one embodiment, the first limiting surface is a conical surface surrounding the central axis of the first limiting member.

[0012] In one embodiment, the second limiting component includes a second mounting member and a second limiting member connected to the second mounting member, the second limiting end being formed in the second limiting member, and the second limiting end being able to engage with the first limiting end when the vehicle tailgate is in a closed state; the second mounting member is used to be movably mounted on the vehicle side panel, and the second mounting member is able to move relative to the vehicle side panel along a second preset direction.

[0013] In one embodiment, the vehicle tailgate limiting structure further includes a locking adjustment assembly connected between the second limiting assembly and the vehicle side panel, for adjusting the movement of the second limiting assembly relative to the vehicle side panel along the second preset direction, and for fixing the second limiting assembly to the vehicle side panel.

[0014] In one embodiment, the locking adjustment assembly includes a first locking member with external threads and a second locking member with internal threads. The first locking member is inserted into the second limiting assembly and the vehicle side panel. The second locking member is threadedly connected to the insertion end of the first locking member. The vehicle side panel has an adjustment hole, the opening of which extends along the second preset direction, and the first locking member is inserted into the adjustment hole.

[0015] On the other hand, embodiments of this application also provide a vehicle, including a body and a tailgate disposed on the body, the tailgate having a tailgate side panel, the body having a body side panel, the vehicle further including at least one vehicle tailgate limiting structure as described in any of the above claims, the first limiting component being mounted on the tailgate side panel; and the second limiting component being mounted on the body side panel.

[0016] In one embodiment, the vehicle includes two tailgate limiting structures, the tailgate sidewalls having opposing side walls along the width of the vehicle body, and two first limiting components respectively installed on the side walls of the tailgate sidewalls; the vehicle body sidewalls having opposing side walls along the width of the tailgate, and two second limiting components respectively installed on the side walls of the vehicle body sidewalls.

[0017] The beneficial effects of the vehicle tailgate limiting structure and vehicle of this application compared with the prior art are as follows: Compared with the prior art, in this vehicle tailgate limiting structure and vehicle, by adding this limiting structure between the tailgate side panel and the vehicle body side panel, the first limiting end of the first limiting component installed on the tailgate side panel can be adjusted in a first preset direction. In addition, the second limiting component installed on the vehicle body side panel can be adjusted in a second preset direction, thereby achieving the purpose of adjusting the contact position, interference amount and squeezing force between the first limiting end and the second limiting end. Based on the principle of action and reaction forces, the tailgate can move relative to the vehicle body in the vehicle width direction, the vehicle vertical direction and the vehicle front and rear direction. The tailgate position adjustment has six degrees of freedom: up, down, left, right, front and rear. The tailgate position adjustment is more flexible. In the later use of the vehicle, when the tailgate has a gap in any direction relative to the vehicle body, the gap can be adjusted, greatly reducing the limitation of gap adjustment.

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] With technological advancements and rising aesthetic standards, the requirements for automotive exterior quality are becoming increasingly stringent. Consequently, the requirements for gaps and clearances between various areas of the vehicle are also increasing, particularly regarding the gap between the tailgate side panel and the body side panel.

[0030] The tailgate side panel refers to the circumferential edge sheet metal structure of the tailgate; the body side panel refers to the circumferential sheet metal structure at the tailgate opening position. When the tailgate is closed, the surface of the circumferential edge sheet metal structure of the tailgate will be parallel to the surface of the circumferential sheet metal structure at the tailgate opening position. Ideally, the tailgate side panel will abut against the body side panel without gaps to achieve the purpose of sealing the vehicle's luggage compartment (also known as the trunk). However, in actual application, when the tailgate is closed, a gap will form between the tailgate side panel and the body side panel.

[0031] Because the tailgate of existing vehicles is connected to the body by hinges, loose hinges can cause serious asymmetry in the gaps between the two sides of the tailgate and the two sides of the body, affecting the appearance and even causing interference between the tailgate side panel and the body side panel, affecting the use of the vehicle.

[0032] Therefore, a limiting structure is added between the tailgate and the body of the vehicle to adjust the gap between the tailgate and the body. However, the limiting structure of the tailgate or trunk lid of the existing vehicle can only limit the gap along the left and right or width direction of the body to adjust the gap between the tailgate and the sides of the body. It cannot meet the gap step adjustment in other areas or directions of the tailgate, and the adjustment is quite limited.

[0033] Considering the above problems, the vehicle tailgate limiting structure of this application can not only realize the gap adjustment between the tailgate and the vehicle body along the width direction (or the left and right direction of the vehicle body), but also realize the adjustment of the tailgate relative to the vehicle body along the vertical and horizontal directions of the vehicle body. That is, it realizes the limiting adjustment of the tailgate relative to the vehicle body in six degrees of freedom in the width direction (left and right direction), the horizontal direction, and the vertical direction, with a wider adjustment range and more flexible adjustment.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0035] Reference Figure 1-3 As shown, this application embodiment provides a vehicle tailgate limiting structure, disposed between the tailgate side panel 4 and the vehicle body side panel 3. The vehicle tailgate limiting structure includes a first limiting component 1 and a second limiting component 2. The first limiting component 1 has a first limiting end, which can switch between multiple adjustment positions along a first preset direction Y. The first preset direction Y is parallel to the direction from the first limiting component 1 toward or away from the second limiting component 2. The first limiting component 1 is used to be installed on the tailgate side panel 4. The second limiting component 2 has a second limiting end, which can abut against the first limiting end when the tailgate is in a closed state. The second limiting component 2 is used to be installed on the vehicle body side panel 3, and the second limiting component 2 can move along a second preset direction X, which is perpendicular to the first preset direction Y.

[0036] in, Figure 1 This is a schematic diagram of the vehicle tailgate limiting structure provided in an embodiment of this application. Figure 1 A schematic diagram showing the connection between the limiting structure hidden behind the tailgate side panel 4 and the vehicle body side panel 3 is shown. Figure 2 This is a schematic diagram of the vehicle tailgate limiting structure provided in an embodiment of this application. Figure 2 The diagram shows the structure of the first limiting component 1 and the second limiting component 2 cooperating when the vehicle tailgate is closed. Figure 3 This is a front view of the vehicle tailgate limiting structure provided in the embodiments of this application. Figure 3 The connection state of the first limiting component 1 and the second limiting component 2 is shown when the vehicle tailgate is closed. Figure 4This is a schematic diagram of the connection between the first limiting component 1 and the rear door side panel 4; Figure 5 A three-dimensional structural diagram showing the connection between the second limiting component 2 and the vehicle side panel 3; Figure 6 A sectional view showing the connection between the second limiting component 2 and the vehicle side panel 3; Figure 7 A sectional view showing the connection between the second mounting component 21 and the vehicle body side panel 3; Figure 8 This is a schematic diagram of the assembly of the limiting structure and the vehicle side panel 3 according to two embodiments of this application.

[0037] It should be noted that the position switching of the first limiting component 1 in the first preset direction Y and the movement of the second limiting component in the second preset direction X are both limited when the back door is closed.

[0038] Specifically, the first limiting component 1 has a movable first limiting end, which can switch between multiple adjustment positions along a first preset direction Y. The first limiting end can switch between multiple adjustment positions along a direction toward or away from the second limiting component 2. It can be understood that the first limiting end can reciprocate relative to the back door side panel 4 along the first preset direction Y, and during the movement of the first limiting end, the first limiting end can be locked in multiple adjustment positions, thereby realizing the extension and retraction of the first limiting end on the first limiting component 1.

[0039] Combination Figure 3 and Figure 4 As shown, a first limiting surface 13 is formed on the first limiting end. The first limiting surface 13 is a surface used to abut against the second limiting surface 23 of the second limiting component 2. The first limiting surface 13 can be a plane or a curved surface. When the first limiting surface 13 is a plane, the first limiting surface 13 forms a preset angle with the first preset direction Y. When the first limiting surface 13 is a curved surface, the tangent at each position of the first limiting surface 13 forms a preset angle with the first preset direction Y. For example, when the first limiting surface 13 is a conical surface, half of the cone angle is the preset angle formed by the first limiting surface 13 and the first preset direction Y.

[0040] It can be seen that the surface of the vehicle side panel 3 (referring to the surface where the second limiting component is installed) generally has a certain angle of inclination with the horizontal direction. This angle of inclination varies depending on the vehicle model. Generally, combined with Figure 1 and Figure 8 As shown, the surface of the vehicle side panel 3 has an inclination angle of 30°-60° relative to the vehicle's driving plane. When the vehicle is on a horizontal plane, the vehicle's driving plane and the horizontal plane are both on the same plane. Therefore, it can be understood that when the tailgate is closed with the vehicle body, the surface of the tailgate side panel 4 (referring to the surface where the first limiting component is installed) will be parallel to the surface of the vehicle side panel 3, so that the surface of the tailgate side panel 4 also has an inclination angle of 30°-60° with the horizontal direction.

[0041] Understandably, when the tailgate is closed, the first preset direction Y can be a direction perpendicular to the surface of the vehicle side panel 3. The first preset direction Y can be decomposed into a direction parallel to the front and rear of the vehicle and a direction perpendicular to the top and bottom of the vehicle. In other words, the tailgate moving along the first preset direction Y means that the tailgate moves along the front and rear and top and bottom of the vehicle.

[0042] Combination Figure 4 As shown, the first limiting component 1 is installed on the surface of the tailgate side panel 4, and the first preset direction Y is perpendicular to the surface of the tailgate side panel 4 where the first limiting component 1 is installed. That is, the movement direction of the first limiting end is perpendicular to the surface of the tailgate side panel 4.

[0043] Combination Figure 3 and Figure 5 As shown, the second limiting component 2 is installed on the surface of the vehicle side panel 3. The second limiting component 2 can move along the second preset direction X. It can be seen that the second limiting component 2 can move relative to the vehicle side panel 3. The second limiting component 2 is movably connected to the vehicle side panel 3. That is to say, the second limiting component 2 can move along the second preset direction X relative to the vehicle side panel 3 to multiple fixed positions for adjusting the position of the second limiting component 2 in the vehicle width direction. Wherein, the second preset direction X is perpendicular to the first preset direction Y. It can be understood that the second preset direction X is parallel to the width direction of the vehicle. That is to say, the second limiting component 2 can reciprocate relative to the vehicle side panel 3 in the width direction of the vehicle. And during the movement of the second limiting component 2, the second limiting component 2 can be locked in multiple fixed positions. It can be understood that when the first limiting end of the first limiting component 1 moves to any adjustment position, it can be matched and abutted against the second limiting end of the second limiting component 2.

[0044] The second limiting surface 23 is the surface that directly interacts with the second limiting component 2 when it is connected to the first limiting component 1. The second limiting surface 23 can be a plane or a curved surface, but it cannot be the surface that does not change its contact position with the first limiting surface 13 when the position of the second limiting component 2 relative to the side wall 3 of the vehicle body changes. It is understood that this limiting structure is used to adjust the position of the tailgate relative to the vehicle body. Therefore, when the position of the first limiting end of the first limiting component 1 and / or the position of the second limiting end of the second limiting component 2 changes, it will affect the meshing or contact position of the first limiting surface 13 and the second limiting surface 23, thereby causing a change in the spatial position of the first limiting component 1, that is, causing the tailgate to be displaced relative to the vehicle body in the first preset direction Y and the second preset direction X, thereby achieving the purpose of adjusting the gap between the tailgate and the vehicle body.

[0045] The process of adjusting the tailgate along the width direction (left and right direction) of the vehicle body using this limiting structure is as follows: Adjusting the fixed position of the second limiting component 2 in the second preset direction X, that is, adjusting the movement of the second limiting component 2 along the second preset direction X. At this time, the position of the second limiting surface 23 changes. When the tailgate is closed, the contact position and the squeezing force of the first limiting surface 13 and the second limiting surface 23 change, so that the first limiting end is subjected to a force in the second preset direction X. Therefore, the first limiting end, the first limiting component 1, and the tailgate will move together in the second direction, thereby changing the relative position of the tailgate and the vehicle body in the second preset direction X, so as to achieve the purpose of adjusting the gap between the tailgate and the width direction of the vehicle body.

[0046] For example, when the second limiting component 2 is located on the side panel 3 of the vehicle body on the left side of the trunk opening, when the second limiting component 2 moves to the left, the amount of interference between the first limiting end and the second limiting component 2 decreases (the amount of interference between the first limiting surface 13 and the second limiting surface 23 decreases). That is, the rightward force exerted by the second limiting component 2 on the first limiting end decreases, which reduces the rightward displacement of the tailgate. In other words, the tailgate will move to the left relative to the vehicle body, and vice versa, thereby achieving the purpose of adjusting the gap between the tailgate and the vehicle body in the width direction.

[0047] The process of adjusting the tailgate along the front-rear and vertical directions of the vehicle body using this limiting structure is as follows: the adjustment position of the first limiting end in the first preset direction Y is adjusted, that is, the extension or retraction of the first limiting end along the first preset direction Y is adjusted. At this time, the position of the first limiting surface 13 changes. When the tailgate is closed, the contact position and the squeezing force of the first limiting surface 13 and the second limiting surface 23 change, so that the first limiting end is subjected to a force in the first preset direction Y. Therefore, the first limiting end, the first limiting component 1 and the tailgate will move together in the front-rear and vertical directions of the vehicle body, thereby changing the relative position of the tailgate with respect to the vehicle body in the front-rear and vertical directions of the vehicle body, so as to achieve the purpose of adjusting the gap between the tailgate and the vehicle body in the front-rear and vertical directions.

[0048] For example, when the first limiting end extends, the tailgate will move to the rear of the vehicle and also move to the top of the vehicle; when the first limiting end retracts, the tailgate will move to the front of the vehicle and also move to the bottom of the vehicle.

[0049] In this embodiment, by adding this limiting structure between the tailgate side panel 4 and the vehicle body side panel 3, the first limiting end of the first limiting component 1 installed on the tailgate side panel 4 can be adjusted in the first preset direction Y. In addition, the second limiting end of the second limiting component 2 installed on the vehicle body side panel 3 can be adjusted in the second preset direction X. This achieves the purpose of adjusting the contact position, interference amount, and squeezing force between the first limiting surface 13 and the second limiting surface 23. Based on the principle of action and reaction forces, the tailgate can move relative to the vehicle body in the vehicle width direction, the vehicle vertical direction, and the vehicle front and rear direction. The tailgate position adjustment has six degrees of freedom: up, down, left, right, front, and rear. The tailgate position adjustment is more flexible. During the later use of the vehicle, when the tailgate has a gap in any direction relative to the vehicle body, the gap can be adjusted, greatly reducing the limitation of gap adjustment.

[0050] In one embodiment, reference Figure 3 and Figure 5-7 As shown, the second limiting component 2 can also move along a third preset direction Z, which is the direction toward or away from the first limiting component 1.

[0051] Specifically, after the second limiting component 2 is installed on the vehicle body, the third preset direction Z is perpendicular to the surface of the vehicle side panel 3. When the surface of the vehicle side panel 3 is a complex curved surface, the surface of the vehicle side panel is the surface on which the second limiting component 2 is installed, and the third preset direction Z is perpendicular to the surface of the vehicle side panel 3 where the second limiting component 2 is installed.

[0052] Generally, the tilt angle of the surface of the vehicle side panel 3 relative to the vehicle's driving plane is 30°-60°. The third preset direction Z is perpendicular to the surface of the vehicle side panel 3. Therefore, it can be known that the angle between the third preset direction Z and the vehicle's driving plane is 30°-60°.

[0053] It should be noted that when the tailgate is closed, the third preset direction Z is the direction perpendicular to the surface of the vehicle side panel 3. The third preset direction Z can be decomposed into a direction parallel to the front and rear of the vehicle and a direction perpendicular to the top and bottom of the vehicle. In other words, the tailgate moving along the third preset direction Z means that the tailgate moves along the front and rear direction and the top and bottom direction of the vehicle.

[0054] When the tailgate is closed, the third preset direction Z is parallel to the first preset direction Y. The movement of the second limiting end of the second limiting component 2 along the third preset direction Z has the same effect as the movement of the first limiting end along the first preset direction Y. That is, the movement of the second limiting component 2 along the third preset direction Z will cause the tailgate to move along the front-rear direction and the up-down direction of the vehicle body.

[0055] Specifically, the height position of the second limiting component 2 in the third preset direction Z is adjusted, that is, the outward protrusion height of the end of the second limiting component 2 relative to the surface of the vehicle side panel 3 in the third preset direction Z is adjusted. At this time, the position of the second limiting surface 23 changes. When the tailgate is closed, the contact position and the squeezing force of the first limiting surface 13 and the second limiting surface 23 change. The first limiting end is subjected to a change in the force in the third preset direction Z. Therefore, the first limiting end, the first limiting component 1 and the tailgate will move together in the front-rear direction and the vertical direction of the vehicle body, thereby changing the relative position of the tailgate with respect to the vehicle body in the front-rear direction and the vertical direction of the vehicle body, so as to achieve the purpose of adjusting the gap between the tailgate and the vehicle body in the front-rear direction and the vertical direction.

[0056] For example, when the protrusion height of the second limiting component 2 relative to the surface of the vehicle side panel 3 increases (that is, when the second limiting component 2 is adjusted to extend outward relative to the vehicle side panel 3), the tailgate will move backward and upward relative to the vehicle. When the protrusion height of the second limiting component 2 relative to the surface of the vehicle side panel 3 decreases (that is, when the second limiting component 2 is adjusted to retract relative to the vehicle side panel 3), the tailgate will move forward and downward relative to the vehicle.

[0057] In this embodiment, by adding a second limiting component 2 to move relative to the side wall 3 of the vehicle body along a third preset direction Z, the purpose of further adjusting the gap between the tailgate and the vehicle body in the front-rear direction and the vertical direction can be achieved. The position of the second limiting component 2 is lower, making the adjustment more comfortable and convenient.

[0058] In one embodiment, reference Figure 2-4 As shown, the first limiting end has a first limiting surface 13, which is gradually tapered in the direction toward the second limiting component 2; the second limiting end has a second limiting surface 23, which is arranged around an axis parallel to the first preset direction Y to form an open curved surface, and the curved surface forms a groove wall with an opening, so that the first limiting surface 13 can abut against the second limiting surface 23.

[0059] Specifically, the first limiting surface 13 is gradually tapered in the direction toward the second limiting component 2, meaning that the first limiting surface 13 is gradually tapered in the first preset direction Y and in the direction away from the back door side panel 4. The first limiting surface 13 is a conical surface that gradually tapes in the direction away from the back door side panel. For example, the first limiting surface 13 can be a conical surface.

[0060] The second limiting component 2 can have a receiving groove. In addition to the groove that can be opposite to the first limiting end (which can be called the upper groove), the receiving groove also has another groove (which can be called the lateral groove) formed on its side. The other groove can also be called the opposing groove or the opposing slot. Therefore, the groove wall of the receiving groove forms the above-mentioned curved surface. It can be seen that the cross-section of the receiving groove is "U" shaped, and the groove wall of the receiving groove is the second limiting surface 23.

[0061] The wall of the receiving groove can be gradually narrowed from the upper opening towards the bottom, so that the wall of the receiving groove forms a conical surface or an inclined curved surface to match the first limiting surface 13 of the first limiting end, forming a surface contact, increasing the contact area between the first limiting surface 13 and the second limiting surface 23, so that the second limiting member 22 supports the first limiting member 12 more stably.

[0062] In one embodiment, reference Figure 3-5 As shown, the first limiting component 1 includes a first mounting member 11 and a first limiting member 12 movably connected to the first mounting member 11. The first limiting member 12 is threaded to the first mounting member 11 around its own central axis, and the central axis of the first limiting member 12 is parallel to the first preset direction Y. A first limiting end is formed at one end of the first limiting member 12 that is away from the first mounting member 11. The first mounting member 11 is used to connect with the back door side panel 4.

[0063] Specifically, the first mounting member 11 may adopt a shell structure, a solid structure, or a frame structure; the first mounting member 11 extends in a columnar shape, and the central axis of the first mounting member 11 is parallel to the first preset direction Y, so the first limiting member 12 can reciprocate along the central axis of the first mounting member 11.

[0064] The first mounting component 11 can be fixedly connected to the side panel of the rear door using welding, bolt assembly, latch or locking pin or other structures.

[0065] The first limiting member 12 is threadedly connected to one end of the first mounting member 11 that extends outward from the back door side panel 4. The rotation axis of the first limiting member 12 relative to the first mounting member 11 is the central axis of the first limiting member 12. When the first limiting member 12 rotates clockwise or counterclockwise, the first limiting member 12 can extend or retract relative to the first mounting member 11 along the first preset direction Y.

[0066] The telescopic end of the first limiting member 12 is the first limiting end. The first limiting end can move closer to or further away from the second limiting component 2 along the first preset direction Y to adjust the amount of interference between the first limiting member 12 and the second limiting component 2, so as to adjust the moving position of the first limiting member 12 and the back door.

[0067] Furthermore, the first limiting surface 13 is a conical surface formed at the first limiting end and surrounding the central axis of the first limiting member 12. Therefore, the first limiting member 12 can adopt a conical block or column structure, and its conical surface is the first limiting surface 13.

[0068] In this embodiment, the first limiting component 1 is connected by a threaded connection between the first mounting part 11 and the first limiting part 12, which enables the first limiting part 12 to move relative to the first mounting part 11 and the back door. This makes adjustment convenient, saves adjustment time, and improves adjustment efficiency.

[0069] In one embodiment, reference Figure 2 , Figure 3 and Figure 5 As shown, the second limiting component 2 includes a second mounting member 21 and a second limiting member 22 connected to the second mounting member 21. The second limiting end is formed in the second limiting member 22 and can be inserted and cooperated with the first limiting end when the vehicle tailgate is in the closed state. The second mounting member 21 is used to be movably mounted on the vehicle side panel 3 and can move relative to the vehicle side panel 3 along a second preset direction X.

[0070] Specifically, the second limiting member 22 has a receiving groove, the groove wall of which is the second limiting surface 23. The groove wall of the receiving groove facing the middle of the vehicle body is provided to form an opposing groove. The first limiting end is inserted into the receiving groove, and the first limiting surface 13 can abut against the groove wall of the receiving groove.

[0071] Combination Figure 6 As shown, the second mounting component 21 adopts a seat structure and is movably connected to the vehicle side panel 3. The second mounting component 21 and the vehicle side panel 3 can be connected by the locking adjustment assembly 5 described below. For details, please refer to the following structural description of the locking adjustment assembly 5.

[0072] Combination Figure 8 As shown, relative to the vehicle body, the second preset direction X can be the width direction of the vehicle body. Therefore, the movement of the second mounting member 21 along the second preset direction X is the movement of the second mounting member 21 relative to the side wall 3 of the vehicle body along the width direction of the vehicle body. For example, the second mounting member 21 moves towards the middle area of ​​the vehicle body along the width direction of the vehicle body, or the second mounting member 21 moves towards the outer side of the vehicle body along the width direction of the vehicle body.

[0073] The second limiting member 22 is fixedly connected to the second mounting member 21, and the fixing method includes welding, bolt assembly connection, buckle connection or locking pin connection, etc.

[0074] The groove wall of the receiving groove forms the second limiting surface 23, and the opposing groove is formed by the through-hole of one side of the receiving groove near the middle of the vehicle body. The opposing groove can also be called the side groove of the receiving groove, and the side groove is opened towards the middle of the vehicle body.

[0075] In this embodiment, the first limiting end is inserted into the receiving groove to achieve the contact between the first limiting surface 13 and the second limiting surface 23. Therefore, by adjusting the position of the second mounting member 21 along the second preset direction X, the contact position and interference between the first limiting surface 13 and the second limiting surface 23 can be changed, thereby achieving the position adjustment of the first limiting end, the first limiting member 12 and the tailgate, so as to achieve the purpose of adjusting the gap between the tailgate and the vehicle body.

[0076] In one embodiment, reference Figure 5 and Figure 6 and Figure 7 As shown, the vehicle tailgate limiting structure also includes a locking adjustment component 5, which is connected between the second limiting component 2 and the vehicle side panel 3 to adjust the movement of the second limiting component 2 relative to the vehicle side panel 3 along the second preset direction X, and to fix the second limiting component 2 and the vehicle side panel 3.

[0077] Specifically, refer to Figure 6 and Figure 7 As shown, the locking adjustment assembly 5 includes a first locking member 52 with external threads, a second locking member 51 with internal threads, and an adjustment pad 53 connected between the second mounting member 21 and the vehicle side panel 3. The first locking member 52 is inserted into the second mounting member 21 and the vehicle side panel 3 in the second limiting assembly 2. The second locking member 51 is threadedly connected to the insertion end of the first locking member 52. The vehicle side panel 3 has an adjustment hole, the opening of which extends along the second preset direction X, and the first locking member 52 is inserted into the adjustment hole.

[0078] Specifically, the first locking member 52 can be a bolt, and the second locking member 51 can be a nut. Through holes are provided at corresponding positions on the second mounting member 21 and the vehicle side panel 3. The first locking member 52 is inserted into the through hole, and its insertion end is threadedly connected to the second locking member 51 to fix the second mounting member 21 and the vehicle side panel 3. By changing the thickness of the adjusting shim 53, the outward protrusion height of the second mounting member 21 and the second limiting member 22 relative to the surface of the vehicle side panel 3 can be adjusted, thereby achieving the purpose of adjusting the movement of the second limiting assembly 2 relative to the vehicle side panel 3 along the third preset direction Z.

[0079] In this embodiment, the adjustment hole is a through hole opened in the side panel 3 of the vehicle body, used to insert the first locking member 52. The opening of the adjustment hole extends along the second preset direction X. Therefore, it can be known that the opening of the adjustment hole has a preset width in the second preset direction X. Thus, the first locking member 52 can move in the adjustment hole along the second preset direction X. Therefore, the second mounting member 21 can move to multiple positions along the first preset direction Y. The first locking member 52 can fix the second mounting member 21 to the side panel 3 of the vehicle body in each position, so as to achieve the purpose of adjusting the movement of the second mounting member 21 and the second limiting member 22 in the second preset direction X.

[0080] This application also provides a vehicle, combined with Figure 8 As shown, the vehicle includes a body and a tailgate disposed on the body. The tailgate has a tailgate side panel 4, and the body has a body side panel 3. The vehicle also includes at least one tailgate limiting structure as described in the above embodiment. A first limiting component 1 is installed on the tailgate side panel 4, and a second limiting component 2 is installed on the body side panel 3.

[0081] The tailgate side panel 4 generally has three sides, forming an angle of approximately 270°. Correspondingly, the trunk opening side panel 3 generally has three sides, also forming an angle of approximately 270°. The tailgate limiting structure can be installed at any position on the extended length of the tailgate side panel 4 and the side panel 3, but the positions of the first limiting component 1 and the second limiting component 2 must be opposite to each other to abut against each other.

[0082] In this embodiment, by adding this limiting structure between the tailgate side panel 4 and the vehicle body side panel 3, the first limiting end of the first limiting component 1 installed on the tailgate side panel 4 can be adjusted in the first preset direction Y. In addition, the second limiting component 2 installed on the vehicle body side panel 3 can be adjusted in the second preset direction X. This achieves the purpose of adjusting the contact position, interference amount, and squeezing force between the first limiting surface 13 and the second limiting surface 23. Based on the principle of action and reaction forces, the tailgate can move relative to the vehicle body in the vehicle width direction, the vehicle vertical direction, and the vehicle front and rear direction. The tailgate position adjustment has six degrees of freedom: up, down, left, right, front, and rear. The tailgate position adjustment is more flexible. During the later use of the vehicle, when the tailgate has a gap in any direction relative to the vehicle body, the gap can be adjusted, greatly reducing the limitation of gap adjustment.

[0083] In one embodiment, reference Figure 8As shown, the vehicle includes two tailgate limiting structures. The tailgate side panel 4 has two opposing side walls along the width direction of the vehicle body, and two first limiting components 1 are respectively installed on the two side walls of the tailgate side panel 4. The vehicle body side panel 3 has two opposing side walls along the width direction of the tailgate, and two second limiting components 2 are respectively installed on the two side walls of the vehicle body side panel 3.

[0084] Specifically, both first limiting components 1 are installed on the tailgate side panel 4, and the two first limiting components 1 are arranged opposite each other in the width direction of the vehicle body. That is to say, the line connecting the two first limiting components 1 is perpendicular to the length direction of the vehicle body.

[0085] Both second limiting components 2 are installed on the side panel 3 of the vehicle body, and the two second limiting components 2 are arranged opposite each other in the width direction of the tailgate, which is also the width direction of the vehicle body. In other words, the line connecting the two second limiting components 2 is perpendicular to the length direction of the vehicle body; the opposing slots of the two second limiting components 22 are arranged opposite each other.

[0086] In this embodiment, two limiting structures are provided on both sides of the vehicle body side panel 3. The two limiting structures can be adjusted in the same direction, or the limiting structure on one side can be adjusted according to the size of the gap, making the limiting structure more flexible in adjusting the gap.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
