Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a sliding door assembly and a vehicle. Background Technology

[0002] In vehicle design, when a horizontally sliding door is used as a door, its lower part is usually connected to the vehicle body via a lower hinge.

[0003] During vehicle assembly or use, the gap between the sliding door and the vehicle body may become uneven, too large, or too small. To correct these gap issues, it is usually necessary to adjust the relative position of the sliding door and the lower hinge. However, this adjustment requires loosening the mounting bolts connecting the sliding door and the lower hinge. Due to the significant weight of the sliding door and the loss of bolt restraint, the door may sag or shift. In practice, at least two people are required to work together: one person holds and stabilizes the sliding door, while the other simultaneously adjusts the position of the lower hinge and attempts to retighten the bolts. The entire adjustment process requires repeated attempts, alignment, and tightening. This method of adjustment is cumbersome and inefficient. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a sliding door assembly and a vehicle.

[0005] The first aspect of this application provides a sliding door assembly, including:

[0006] Sliding door with adjustment holes;

[0007] A hinge is provided on one side of the sliding door, and the hinge is provided with mounting holes;

[0008] The pin assembly includes a connecting plate, a connecting shaft, an eccentric pin, and a limiting member. The connecting shaft and the eccentric pin are respectively connected to both sides of the connecting plate. The connecting shaft is rotatably inserted into the assembly hole, and the eccentric pin is inserted into the adjustment hole. The connecting shaft and the connecting plate are concentrically arranged, and the eccentric pin is eccentrically arranged with respect to the connecting plate.

[0009] A first clamping surface is formed on the connecting disc or the connecting shaft. The limiting member is connected to the end of the connecting shaft away from the connecting disc, and a second clamping surface is formed on the limiting member. The second clamping surface and the first clamping surface clamp the hinge. Rotating the limiting member causes the connecting shaft to rotate against the clamping force of the first clamping surface and the second clamping surface, and the connecting shaft causes the eccentric pin to rotate eccentrically to drive the sliding door to move relative to the hinge in a first direction.

[0010] Optionally, the end of the connecting shaft away from the connecting disc is threaded, and the limiting member includes a nut, which is threadedly connected to the connecting shaft.

[0011] Optionally, a baffle is provided between the nut and the hinge, the baffle is sleeved on the connecting shaft and forms the second clamping surface, the second clamping surface abuts against the hinge.

[0012] Optionally, the nut is provided with a first positioning hole in the radial direction, and the connecting shaft is provided with a second positioning hole in the radial direction. The positioning pin is inserted into the first positioning hole and the second positioning hole to make the nut and the connecting shaft form a circumferential limit.

[0013] Optionally, the connecting shaft is a stepped shaft, the mounting hole is a stepped hole, the stepped surface of the stepped shaft forms the first clamping surface, and the first clamping surface abuts against the stepped surface of the stepped hole.

[0014] Optionally, the adjusting hole is an oblong hole, and the eccentric pin is slidably inserted into the oblong hole.

[0015] Optionally, the adjustment hole extends in a horizontal direction.

[0016] Optionally, the sliding door has a scale line on the side near the hinge, and the hinge has a reading part for reading the scale line.

[0017] Optionally, the hinge includes a hinge plate and a main body connected to the bottom side of the hinge plate, and the mounting hole is provided on the hinge plate;

[0018] The hinge plate is fixedly connected to the sliding door by multiple fasteners. The hinge plate is provided with multiple mounting holes corresponding to the multiple fasteners, and the multiple mounting holes are arranged around the assembly hole.

[0019] A second aspect of this application provides a vehicle including a sliding door assembly as described in any of the preceding claims.

[0020] The technical solution provided in this application has the following advantages compared with the prior art:

[0021] The sliding door assembly provided in this embodiment has an adjustment hole on the sliding door and an assembly hole on the hinge. The connecting shaft of the pin assembly passes through the assembly hole, and the eccentric pin is inserted into the adjustment hole. A limiting member is connected to the connecting shaft, so that the first clamping surface and the second clamping surface clamp the hinge. When the limiting member is not subjected to external force, the clamping force of the first clamping surface and the second clamping surface restricts the rotation of the connecting shaft. When it is necessary to adjust the relative position of the sliding door and the hinge in the first direction, an external force is applied to the limiting member, so that the connecting shaft overcomes the clamping force and drives the eccentric pin to rotate. The eccentricity between the eccentric pin and the connecting shaft is converted into a thrust along the first direction, so that the eccentric pin pushes the sliding door to move along the first direction. The pin assembly is clamped on the hinge, so that the pin assembly can maintain a stable position when it is not subjected to external force. Moreover, when adjusting the position of the sliding door, the clamping force can share part of the weight of the sliding door, reducing the force required to maintain the position of the sliding door. Workers can use tools to drive the limit component to rotate with one hand, causing the eccentric pin to rotate eccentrically and drive the sliding door to move in the first direction. This simplifies the operation of adjusting the relative position of the sliding door and the vehicle body, avoids the need for multiple people to cooperate when adjusting the position of the sliding door, reduces the workload of adjusting the sliding door, and improves the assembly efficiency of the sliding door.

[0032] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0034] Reference Figures 1 to 7 As shown, the first aspect of this application provides a sliding door assembly, including: a sliding door 1 with an adjustment hole 11; a hinge 2 disposed on one side of the sliding door 1, and the hinge 2 having an assembly hole 21; and a pin assembly 3 including a connecting plate 31, a connecting shaft 32, an eccentric pin 33, and a limiting member 34. The connecting shaft 32 and the eccentric pin 33 are respectively connected to both sides of the connecting plate 31. The connecting shaft 32 rotatably passes through the assembly hole 21, and the eccentric pin 33 is inserted into the adjustment hole 11. The connecting shaft 32 and the connecting plate 31 are concentrically arranged. The eccentric pin 33 is eccentrically positioned with the connecting plate 31; a first clamping surface is formed on the connecting plate 31 or the connecting shaft 32; a limiting member 34 is connected to the end of the connecting shaft 32 away from the connecting plate 31, and a second clamping surface is formed on the limiting member 34; the second clamping surface and the first clamping surface clamp the hinge 2; rotating the limiting member 34 causes the connecting shaft 32 to rotate against the clamping force of the first clamping surface and the second clamping surface, and through the connecting shaft 32, the eccentric pin 33 is eccentrically rotated to drive the sliding door 1 to move relative to the hinge 2 in the first direction.

[0035] Specifically, the sliding door 1 is the door of the vehicle. An adjustment hole 11 is opened at the bottom of the door body of the sliding door 1. The adjustment hole 11 is a through hole on the sliding door 1. The size of the adjustment hole 11 can be larger than the size of the eccentric pin 33, so that the eccentric pin 33 can move within a certain range in the adjustment hole 11. As long as the eccentric pin 33 abuts against the inner wall of the top side of the adjustment hole 11, the eccentric pin 33 can be eccentrically rotated around the connecting shaft 32, and the eccentric pin 33 can push the sliding door 1 to move relative to the hinge 2 in the first direction.

[0036] Figure 1 and Figure 2 The direction indicated by the middle arrow is the first direction a, which is perpendicular to the chassis structure of the vehicle body used to connect the hinge 2. When the sliding door 1 moves relative to the hinge 2 along the first direction a, the gap between the sliding door 1 and the vehicle body can be increased or decreased to correct the gap problem between the sliding door 1 and the vehicle body.

[0037] The hinge 2 mentioned above is fixed to the side of the vehicle chassis. Multiple through holes 24 are typically provided on the hinge 2 as mounting holes 24. A bolt is installed in each mounting hole 24 to connect to the sliding door 1. Tightening the bolts fixes the hinge 2 to the sliding door 1. During assembly, the vehicle body is usually placed on a horizontal surface. After the sliding door 1 is connected to the hinge 2, the relative position of the sliding door 1 and the vehicle body needs to be adjusted vertically to adjust the gap between them, i.e., the first direction a is the vertical direction. The weight of the sliding door 1 itself causes it to move downwards relative to the vehicle in the vertical direction. The vertical movement of the sliding door 1 relative to the hinge 2 requires overcoming a clamping force, which can share some of the weight of the sliding door 1, reducing the force required for the operator to maintain the position of the sliding door 1.

[0038] Of course, in some assembly conditions, the vehicle body can be tilted relative to the horizontal plane. In this case, when adjusting the gap between the sliding door 1 and the vehicle body, the sliding door 1 needs to move relative to the hinge 2 in a direction perpendicular to the chassis of the vehicle body. That is, the first direction a is perpendicular to the chassis of the vehicle body used to install the hinge 2. With the chassis of the vehicle tilted and the first direction a also tilted relative to the horizontal plane, the weight of the sliding door 1 has a component in the first direction a, so that the sliding door 1 will still move downward relative to the vehicle body under its own weight. However, the movement of the sliding door 1 relative to the hinge 2 along the first direction a requires overcoming the clamping force, so that the clamping force can share part of the weight of the sliding door 1, reducing the force required for the operator to maintain the position of the sliding door 1.

[0039] When adjusting the position of the sliding door 1 and the hinge 2, loosen the bolts while keeping the bolts connected to the sliding door 1. The sliding door 1 is connected to the hinge 2 by multiple bolts. Rotate the pin assembly 3, and the connecting shaft 32 drives the eccentric pin 33 to rotate. The eccentric pin 33 abuts against the inner wall of the adjustment hole 11, so that the eccentric pin 33 pushes the sliding door 1 to move relative to the hinge 2 in the first direction a, thereby adjusting the gap between the sliding door 1 and the vehicle body.

[0040] The aforementioned mounting hole 21 is provided on the hinge 2. The diameter of the mounting hole 21 is slightly larger than the diameter of the connecting shaft 32, so that the connecting shaft 32 can rotate in the mounting hole 21.

[0041] The connecting plate 31 can be a circular structure or a rectangular plate. The connecting shaft 32 and the eccentric pin 33 can be fixedly installed on both sides of the connecting plate 31 by welding. Alternatively, the connecting plate 31, the connecting shaft 32 and the eccentric pin 33 can be integrated into a single structure and formed by injection molding in a mold.

[0042] The movement trajectory of the eccentric pin 33 is circular, which is the first circle. The first circle is divided into two arcs in the first direction a. When the eccentric pin 33 moves from one end to the other on the upper arc, the position of the eccentric pin 33 in the first direction a first rises and then falls. When the eccentric pin 33 moves from one end to the other on the lower arc, the position of the eccentric pin 33 in the first direction a first falls and then rises.

[0043] The axis of the connecting shaft 32 coincides with the central axis of the connecting plate 31, and the axis of the eccentric pin 33 is spaced apart from and parallel to the central axis of the connecting plate 31, so that the eccentric pin 33 is eccentrically positioned relative to the connecting shaft 32. Therefore, when the connecting shaft 32 rotates around its own axis, the eccentric pin 33 can also rotate around the axis of the connecting shaft 32, causing the eccentric pin 33 to displace in the first direction a, thereby enabling the eccentric pin 33 to drive the sliding door 1 to move relative to the hinge 2.

[0044] The limiting member 34 can be a nut. The outer wall of the end of the connecting shaft 32 away from the connecting plate 31 is threaded. The nut is threaded with the connecting shaft 32, so that the limiting member 34 can be installed on the connecting shaft 32. The side of the connecting plate 31 facing the connecting shaft 32 is the first clamping surface, and the side of the nut near the hinge 2 is the second clamping surface. When the nut is tightened, the second clamping surface abuts against one side of the hinge 2. The reaction force of the hinge 2 on the first clamping surface is applied to the connecting shaft 32, causing the first clamping surface on the connecting plate 31 to move towards the hinge 2 to abut against the hinge 2, so that the first clamping surface and the second clamping surface clamp the hinge 2.

[0045] Alternatively, the limiting component 34 can be a buckle. The buckle is engaged with the end of the connecting shaft 32 away from the connecting plate 31. The side of the buckle facing the hinge 2 is the second clamping surface, and the side of the connecting plate 31 facing the connecting shaft 32 is the first clamping surface. The first and second clamping surfaces abut against the hinge 2. The friction between the buckle and the connecting shaft 32 ensures that the first and second clamping surfaces remain in contact with the hinge 2, so that the connecting shaft 32 needs to overcome the clamping force of the first and second clamping surfaces when it rotates.

[0046] The aforementioned assembly hole 21 may be provided with a stepped structure, the connecting shaft 32 has a stepped abutment portion, the side of the abutment portion near the limiting member 34 is the first clamping surface, the second clamping surface of the limiting member 34 abuts against one side of the hinge 2, the connecting shaft 32 passes through the assembly hole 21, and the second clamping surface of the abutment portion abuts against the stepped structure in the assembly hole 21.

[0047] Both the first clamping surface and the second clamping surface abut against the hinge 2. The force exerted by the first clamping surface and the second clamping surface on the hinge 2, together with the static friction force on the first clamping surface and the second clamping surface, constitutes the clamping force. When the pin assembly 3 rotates, it needs to overcome the clamping force to rotate. When the limiting member 34 is not subjected to external force, the clamping force can keep the connecting shaft 32 stable in the assembly hole 21.

[0048] When adjusting the relative position of the sliding door 1 and the hinge 2, the connecting shaft 32 needs to overcome the clamping force to rotate. Usually, a driving force is applied to the limiting member 34 to drive the connecting shaft 32 to rotate. After the sliding door 1 moves to the desired position, a force needs to be continuously applied to the limiting member 34 to maintain the position of the sliding door 1. At this time, the clamping force can share part of the weight of the sliding door 1, reducing the force required to maintain the position of the sliding door 1.

[0049] In specific use, the sliding door assembly provided in this application embodiment has the hinge 2 installed on the vehicle body, the connecting shaft 32 passing through the assembly hole 21, the eccentric pin 33 plugged into the adjustment hole 11, the limiting member 34 connected to the connecting shaft 32, and the hinge 2 and the sliding door 1 connected to each other by fasteners.

[0050] When it is necessary to adjust the relative position of sliding door 1 and hinge 2 in the first direction a to correct the gap between sliding door 1 and the vehicle body, first loosen the fasteners to allow a certain range of movement between sliding door 1 and hinge 2. Use a wrench to rotate the limiting member 34. The driving force applied by the wrench to the limiting member 34 drives the connecting shaft 32 to rotate. The rotation of the connecting shaft 32 drives the eccentric pin 33 to rotate eccentrically around the axis of the connecting plate 31. The eccentricity between the eccentric pin 33 and the connecting shaft 32 is converted into a vertical thrust, which pushes the sliding door 1 to move up and down relative to the hinge 2. After the sliding door 1 moves to the desired position, the operator continuously applies force to the wrench with one hand to keep the position of the sliding door 1 stable by applying continuous force to the limiting member 34. The other hand holds a power tool or screwdriver to tighten the fasteners so that the hinge 2 and the sliding door 1 are fixedly connected by the fasteners.

[0051] The sliding door assembly provided in this embodiment has an adjustment hole 11 on the sliding door 1 and an assembly hole 21 on the hinge 2. The connecting shaft 32 of the pin assembly 3 passes through the assembly hole 21, and the eccentric pin 33 is inserted into the adjustment hole 11. The limiting member 34 is connected to the connecting shaft 32, so that the first clamping surface and the second clamping surface clamp the hinge 2. When the limiting member 34 is not subjected to external force, the clamping force of the first clamping surface and the second clamping surface restricts the rotation of the connecting shaft 32. When it is necessary to adjust the relative position of the sliding door 1 and the hinge 2 in the first direction a, an external force is applied to the limiting member 34, so that the connecting shaft 32 overcomes the clamping force and drives the eccentric pin 33 to rotate. The eccentricity between the eccentric pin 33 and the connecting shaft 32 is converted into a thrust along the first direction a, so that the eccentric pin 33 pushes the sliding door 1 to move along the first direction a. The pin assembly 3 is clamped onto the hinge 2, ensuring its stable position when not subjected to external force. Furthermore, when adjusting the position of the sliding door 1, the clamping force can share some of the sliding door 1's weight, reducing the force required to maintain its position. Workers can use tools to drive the limiting member 34 to rotate with one hand, causing the eccentric pin 33 to rotate eccentrically and drive the sliding door 1 to move along the first direction a. This simplifies the operation of adjusting the relative position of the sliding door 1 to the vehicle body, avoids requiring multiple people to cooperate when adjusting the sliding door 1, reduces the workload of adjusting the sliding door, and improves the assembly efficiency of the sliding door 1.

[0052] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the end of the connecting shaft 32 away from the connecting disc 31 is threaded, and the limiting member 34 includes a nut, which is threadedly connected to the connecting shaft 32.

[0053] With this configuration, the nut is threaded onto the connecting shaft 32. Tightening the nut generates an axial locking force, causing the first and second clamping surfaces to press against the hinge 2, ensuring that there is no wobbling between the hinge 2 and the pin assembly 3. By adjusting the tightness of the nut to adjust its position on the connecting shaft 32, the clamping force of the first and second clamping surfaces can be controlled, thus balancing adjustment flexibility and operational stability. Reversing the rotation of the nut will separate it from the connecting shaft 32, facilitating the removal of the pin assembly 3 from the hinge 2.

[0054] Specifically, an external thread is machined on the outer wall of the connecting shaft 32, and a nut is fitted onto the connecting shaft 32 to make the nut threadedly connected to the connecting shaft 32. When the nut is tightened, the nut can move toward the connecting plate 31. A stop block can be provided at the end of the external thread near the connecting plate 31. The nut is tightened to the stop block and abuts against the stop block. At this time, the nut abuts against the hinge 2. The force applied to the nut in the tightening direction is transmitted to the connecting shaft 32 through the stop block, so that the nut and the connecting shaft 32 rotate together.

[0055] The aforementioned nut is subjected to a force along the tightening direction to drive the connecting shaft 32 to rotate. When the connecting shaft 32 rotates one revolution, the eccentric pin 33 also rotates one revolution. When the eccentric pin 33 rotates, it will drive the sliding door 1 to move along the first direction a. When the rotation angle of the eccentric pin 33 is too large and the sliding door 1 misses the required position, the force is continued to be applied to the nut along the tightening direction, so that the eccentric pin 33 drives the sliding door 1 to move to the required position in the subsequent rotation, or so that the eccentric pin 33 drives the sliding door 1 to move to the required position in the next rotation cycle.

[0056] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, a baffle 35 is provided between the nut and the hinge 2. The baffle 35 is sleeved on the connecting shaft 32 and forms a second clamping surface, which abuts against the hinge 2.

[0057] With this design, the baffle 35 reduces the pressure of the nut on the hinge 2, preventing the nut from scratching the surface of the hinge 2 or causing local deformation of the hinge 2 when tightening, thus extending the life of the hinge 2.

[0058] Specifically, the baffle 35 is an annular plate, which is sleeved on the connecting shaft 32. The baffle 35 is located between the nut and the hinge 2, and the side of the baffle 35 facing the hinge 2 is the second clamping surface. When the nut is tightened, pressure is applied to the baffle 35 towards the hinge 2 so that the second clamping surface abuts against the hinge 2.

[0059] In some embodiments, the nut is provided with a first positioning hole in the radial direction, the connecting shaft 32 is provided with a second positioning hole in the radial direction, and the positioning pin is inserted into the first positioning hole and the second positioning hole so that the nut and the connecting shaft 32 form a circumferential limit.

[0060] Specifically, hinge 2, being a standard component, maintains a stable thickness. A second positioning hole can be drilled at a predetermined position on connecting shaft 32 based on the thickness of hinge 2. When the nut is connected to connecting shaft 32 and moves to a position where both the first and second clamping surfaces abut against hinge 2, the second positioning hole is located on the side of hinge 2 facing away from sliding door 1 and is coaxial with the first positioning hole. A positioning pin is inserted into the first and second positioning holes to maintain a stable relative position between the nut and connecting shaft 32. The nut can synchronously drive connecting shaft 32 to rotate when rotating clockwise or counterclockwise.

[0061] Alternatively, after tightening the nut onto the connecting shaft 32, drill holes in the nut and connecting shaft 32 to form a first positioning hole and a second positioning hole. Insert the positioning pin into the first positioning hole and the second positioning hole to fix the nut and connecting shaft 32 to each other.

[0062] Reference Figures 4 to 7 As shown, in some embodiments, the connecting shaft 32 is a stepped shaft, the mounting hole 21 is a stepped hole, the stepped surface of the stepped shaft forms a first clamping surface, and the first clamping surface abuts against the stepped surface of the stepped hole.

[0063] With this configuration, the stepped hole and the stepped shaft have a specific insertion direction when they are engaged. That is, the stepped shaft can only be inserted into the stepped hole from the end of the stepped hole facing the sliding door 1, ensuring that the eccentric pin 33 is on the side of the hinge 2 facing the sliding door 1, and preventing the pin assembly 3 from being installed in reverse on the hinge 2.

[0064] Specifically, the connecting shaft 32 can include a first shaft 321 and a second shaft 322 coaxially arranged. The second shaft 322 is fixedly connected to the connecting disk 31, and the first shaft 321 is connected to the end of the second shaft 322 away from the connecting disk 31. The diameter of the first shaft 321 is smaller than the diameter of the second shaft 322, so that the first shaft 321 and the second shaft 322 form a stepped shaft. The side of the second shaft 322 away from the connecting disk 31 is the first clamping surface.

[0065] An annular boss 211 is formed in the aforementioned assembly hole 21. The annular boss 211 is located at the end of the inner wall of the assembly hole 21 away from the sliding door 1. The first shaft 321 passes through the annular boss 211. The side of the annular boss 211 near the sliding door 1 is a stepped surface. When the connecting shaft 32 passes through the assembly hole 21, the first shaft 321 passes through the inside of the annular boss 211. The second shaft 322 is located on the side of the annular boss 211 near the sliding door 1, and the first clamping surface on the second shaft 322 abuts against the stepped surface of the annular boss 211.

[0066] Reference Figures 4 to 7 As shown, in some embodiments, the adjustment hole 11 is an oblong hole, and the eccentric pin 33 is slidably inserted into the oblong hole.

[0067] With this configuration, the horizontal displacement of the eccentric pin 33 will cause the eccentric pin 33 to slide within the elongated hole, reducing the force exerted on the sliding door 1 in the horizontal direction when the eccentric pin 33 moves along a circular trajectory.

[0068] Specifically, the adjustment hole 11 is an elongated hole extending on the sliding door 1, and the eccentric pin 33 can slide in the elongated hole along the extension direction of the elongated hole; the elongated hole can be extended perpendicular to the first direction a, or it can be extended along the first direction a, or the extension direction of the elongated hole can be angled with the first direction a.

[0069] When the eccentric pin 33 moves along a circular trajectory, it abuts against the inner walls of the top and bottom sides of the elongated hole. The vertical movement of the eccentric pin 33 will exert a vertical force on the inner walls of the top and bottom sides of the elongated hole. The horizontal movement of the eccentric pin 33 will cause it to slide inside the elongated hole.

[0070] Reference Figures 4 to 7 As shown, in some embodiments, the extension direction of the adjustment hole 11 is perpendicular to the first direction a. With this configuration, the eccentric pin 33 moves on a circular trajectory, and the displacement of the eccentric pin 33 in the direction perpendicular to the first direction a is within the adjustment hole 11, so that the eccentric pin 33 will only drive the sliding door 1 to move in the first direction a during rotation.

[0071] Specifically, the adjustment hole 11 extends horizontally. The two ends of the adjustment hole 11 are respectively on the circular trajectory where the eccentric pin 33 moves. During the movement of the eccentric pin 33 on the circular trajectory, the displacement of the eccentric pin 33 perpendicular to the first direction a is within the adjustment hole 11, so that when the eccentric pin 33 rotates, it will only drive the sliding door 1 to move in the first direction a.

[0072] Reference Figures 4 to 7 As shown, in some embodiments, the sliding door 1 has a scale line on the side near the hinge 2, and the hinge 2 has a reading part for reading the scale line.

[0073] With this setup, the distance between hinge 2 and sliding door 1 can be accurately quantified through the cooperation of the reading section and the scale lines, thereby improving the accuracy of adjusting the relative position of sliding door 1 and hinge 2.

[0074] Specifically, the scale line extends along the first direction a, and the top edge of the hinge 2 can be selected to form a reading part. The scale line is set at a position opposite to the top edge of the hinge 2. When the hinge 2 and the sliding door 1 move relative to each other in the first direction, the top edge of the hinge 2 moves to different positions of the scale line, and the relative position of the hinge 2 and the sliding door 1 can be accurately read through the scale line.

[0075] Alternatively, the reading section can be a pointer located on the edge of the hinge 2. The pointer points to the scale line. When the sliding door 1 moves relative to the hinge 2 in the first direction a, the pointer moves relative to the sliding door 1 and moves on different scales.

[0076] Reference Figures 1 to 3 As shown, in some embodiments, the hinge 2 includes a hinge plate 22 and a main body 23 connected to the bottom side of the hinge plate 22. The mounting hole 21 is provided on the hinge plate 22. The hinge plate 22 is fixedly connected to the sliding door 1 by a plurality of fasteners. The hinge plate 22 is provided with a plurality of mounting holes 24 corresponding to the plurality of fasteners. The plurality of mounting holes 24 are arranged around the mounting hole 21.

[0077] With this configuration, the hinge plate 22 is connected to the sliding door 1, increasing the contact area between the hinge 2 and the sliding door 1. Furthermore, the multiple connection points between the hinge plate 22 and the sliding door 1 enhance the stability of the connection. When the hinge 2 moves relative to the sliding door 1, the bolts in the multiple mounting holes 24 evenly distribute the force applied by the sliding door 1, improving the trajectory stability of the hinge 2 and the sliding door 1 during relative movement.

[0078] Specifically, the hinge plate 22 is a panel structure, and the main body 23 includes sliding structures such as pulleys and guide rails. The sliding structure is slidably connected to the vehicle body, and the hinge plate 22 is fixedly connected to the sliding structure. The hinge plate 22 is provided with multiple through holes as mounting holes 24, and the sliding door 1 is provided with multiple screw holes. The multiple screw holes are set one-to-one with the multiple mounting holes 24. Each mounting hole 24 is provided with a bolt, and the bolt is threadedly connected to the corresponding screw hole to fix the hinge plate 22 to the sliding door 1 through multiple bolts.

[0079] The hinge plate 22 can be provided with three mounting holes 24, so that there are three connection points between the hinge plate 22 and the sliding door 1. The three mounting holes 24 are arranged in a triangle. The assembly hole 21 is provided between two mounting holes 24 along the first direction a, and the assembly hole 21 is provided between two mounting holes 24 that are perpendicular to the first direction a.

[0080] A second aspect of this application provides a vehicle including a sliding door assembly as described in any of the preceding claims.

[0081] Specifically, when the sliding door assembly described above is used in the vehicle, during the assembly of the sliding door 1, by applying force to the limiting member 34, the connecting shaft 32 can be driven to rotate, thereby causing the eccentric pin 33 to rotate eccentrically, so as to adjust the relative position of the sliding door 1 and the hinge 2 in the first direction a, simplifying the operation of adjusting the position of the sliding door 1 and improving the assembly efficiency of the sliding door 1.

[0082] In the specific use of the sliding door assembly provided in this application embodiment and the vehicle, the vehicle chassis is horizontally positioned, with the vertical direction as the first direction a. The main body 23 of the hinge 2 is slidably connected to the vehicle body, and multiple bolts are passed through multiple mounting holes 24 and connected to the sliding door 1. The connecting shaft 32 is inserted into the assembly hole 21, so that the stepped shaft and the stepped surface abut against each other, and the eccentric pin 33 is inserted into the adjustment hole 11. The nut of the limiting member 34 is connected to the connecting shaft 32 so that the first clamping surface and the second clamping surface clamp the hinge plate 22. At this time, the positioning pin is inserted into the first positioning hole and the second positioning hole, so that the nut is fixedly connected to the connecting shaft 32. The hinge plate 22 and the sliding door 1 are connected to each other by multiple bolts.

[0083] When it is necessary to adjust the relative position of the sliding door 1 and hinge 2 in the vertical direction to correct the gap between the sliding door 1 and the vehicle body, first loosen the bolts in the mounting hole 24 to allow a certain range of movement between the sliding door 1 and hinge 2. Use a wrench to rotate the nut. The driving force applied by the wrench to the nut drives the connecting shaft 32 to rotate. The rotation of the connecting shaft 32 drives the eccentric pin 33 to rotate eccentrically around the axis of the connecting plate 31. The vertical displacement of the eccentric pin 33 applies a force to the top and bottom inner walls of the adjusting hole 11, so that the eccentric pin 33 pushes the sliding door 1 to move up and down relative to the hinge 2 in the vertical direction. The horizontal displacement of the eccentric pin 33 causes the eccentric pin 33 to slide in the adjusting hole 11.

[0084] After the sliding door 1 is moved to the desired position, the worker applies continuous force to the wrench with one hand to keep the nut under continuous force and stabilize the position of the sliding door 1, while holding a power tool or screwdriver with the other hand to tighten the bolt so that the hinge 2 is fixedly connected to the sliding door 1 by the bolt.
