[0007] In an optional embodiment, the sliding door includes a sliding door body and a movable hinge connected together. The movable hinge connects the sliding door mounting structure and the sliding door body.

[0030] Please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the limiting structure of an existing sliding door in the fully closed position. Figure 7 This is a schematic diagram of the limiting structure of an existing sliding door in the fully open position. To limit the sliding door 10 in both the fully open and fully closed positions, the existing technology uses two limiting blocks: a fully closed limiting block 40 and a fully open limiting block 50. Specifically, the fully closed limiting block 40 and the fully open limiting block 50 are located at different positions on the bottom of the vehicle body. When the sliding door 10 is in the fully closed position, the fully closed limiting block 40 abuts against the sliding door 10, using friction to limit the sliding door 10 in the fully closed position. When the sliding door 10 is in the fully open position, the fully open limiting block 50 cooperates with the sliding door in the opening direction of the sliding door 10 to limit its opening and prevent the sliding door 10 from opening too wide.
[0031] As described above, the existing sliding door limiting assembly uses two limiting blocks to achieve the limiting of the sliding door 10 in the fully closed and fully open positions. However, assembling these two limiting blocks is cumbersome and time-consuming, and they also negatively impact the aesthetic design of the sliding door. It should be noted that... Figure 6 and Figure 7 The exemplary figures of the embodiments in this application are only used to assist in the illustration of the prior art, and in fact, they do not represent the actual solutions of the prior art.
[0032] Therefore, please refer to Figures 1 to 4 This application provides a vehicle (not shown) including a sliding door limiting assembly. The sliding door limiting assembly includes a sliding door 10, a sliding door mounting structure, and a limiting block 20. The sliding door 10 is mounted on the sliding door mounting structure and is slidable relative to the sliding door mounting structure. The limiting block 20 is disposed on the sliding door mounting structure and includes a first limiting part 21 and a second limiting part 22. The sliding door 10 has an open position and a closed position. In the open position, the first limiting part 21 engages with the sliding door 10 in the opening direction, and in the closed position, the second limiting part 22 engages with the sliding door 10 in the closing direction.
[0033] By setting a limiting block 20, which integrates a first limiting part 21 and a second limiting part 22, the sliding door 10 is limited in both the open and closed positions. That is, the limiting block 20 can provide bidirectional constraint on the sliding door 10. Compared with the traditional design of two independent limiting blocks 20, the integrated limiting block 20 provided in this application only uses one independent limiting block 20, which can ensure that the opening and closing range of the sliding door 10 is within a safe and controllable range, and is conducive to saving costs and assembly time.
[0034] It should be noted that the "open position" refers to the fully open position of the sliding door 10 relative to the vehicle body, that is, the extreme open position of the sliding door 10. When the sliding door 10 is in this position, the user cannot continue to move the sliding door in the opening direction. The "closed position" refers to the fully closed position of the sliding door 10 relative to the vehicle body. When the sliding door 10 is in this position, the sliding door 10 completely closes the vehicle's entry and exit passage, and the user cannot enter or exit the vehicle through this sliding door. However, it is not limited to this; for example, the "open position" can also refer to the half-open position of the sliding door 10. In addition, the vehicle also includes the body, and the structural part of the body used to install the sliding door 10 is the sliding door mounting structure.
[0035] The sliding door 10 can open and close in the direction of the vehicle's length (wherein the sliding door 10 is located). Figure 1 The X-direction can also be the vehicle's height direction (in the center X direction). Figure 1(Z-direction). In this embodiment, the opening and closing directions of the sliding door 10 both refer to the length direction of the vehicle. The limiting block 20 is made of flexible material, including but not limited to rubber, to achieve elastic limiting and reduce abnormal noise during the limiting process.
[0036] In one embodiment, the first limiting part 21 includes a first limiting surface, which is perpendicular to the opening direction of the sliding door 10. In the open position, the first limiting surface and the sliding door 10 are in a limiting engagement along the opening direction of the sliding door 10.
[0037] Specifically, the first limiting surface is along the height direction of the vehicle ( Figure 1 Extending in the Z-direction and the width direction (not shown), when the sliding door 10 slides to the open position, the sliding door 10 abuts against the first limiting surface, so that the sliding door 10 cannot continue to slide in the opening direction, thereby limiting the sliding door 10 in the opening direction.
[0038] In a further embodiment, please refer to Figure 1 and Figure 3 The sliding door 10 includes a sliding door body 11 and a movable hinge 12. The movable hinge 12 connects the sliding door mounting structure and the sliding door body 11, allowing the sliding door body 11 to move relative to the sliding door mounting structure. In the open position, a first limiting surface engages with the movable hinge 12 in the opening direction of the sliding door body 11. Specifically, in the open position, the first limiting surface and the movable hinge are in contact with each other, preventing the movable hinge from moving in the opening direction of the sliding door, thereby limiting the sliding door 10.
[0039] In one embodiment, the second limiting portion 22 is perpendicular to the closing direction of the sliding door 10. Figure 2 The second limiting part 22 protrudes towards the sliding door 10 in the Y direction. In the closed position, the second limiting part 22 abuts against the sliding door 10 in the protruding direction. That is, when the sliding door 10 is in the closed position, the second limiting part 22 and the sliding door 10 are pressed against each other. Due to the pressing, there is a frictional force between the second limiting part 22 and the sliding door 10 in the closing direction of the sliding door 10. The second limiting part 22 limits the sliding door 10 through the frictional force between it and the sliding door 10.
[0040] In one embodiment, a plurality of raised ribs 221 are provided at the point where the second limiting part 22 abuts against the sliding door 10, and the raised ribs 221 are spaced apart along the closing direction of the sliding door 10. Since the open position is the fully open position of the sliding door 10, which is only used under extreme conditions and has a low frequency of use, while the closed position of the sliding door 10 has a higher frequency of use and is a frequently used contact surface, multiple raised ribs 221 are provided at the point where the second limiting part 22 abuts against the sliding door 10, rather than the entire surface. This improves the elasticity of the second limiting part 22, thereby enhancing the stability of the contact and the quietness during operation. Furthermore, by spaced the raised ribs 221 along the closing direction of the sliding door 10, it is easier for the sliding door 10 to compress the raised ribs 221 when closing, thereby increasing the contact force between the raised ribs 221 and the sliding door 10, and thus improving the reliability of the limiting function of the sliding door 10 in the closed position.
[0041] In one embodiment, the sliding door 10 includes a limiting mating surface, which has a concave surface and a convex surface. At least two of the convex ribs 221 have different protrusion lengths. In the closed position, the convex rib 221 with the longer protrusion length abuts against the concave surface, and the convex rib 221 with the shorter protrusion length abuts against the convex surface, so that all the convex ribs 221 fit against the limiting mating surface, thereby improving the reliability of the sliding door 10 in the closed position.
[0042] like Figure 4 In the illustrated embodiment, the second limiting part 22 has three protruding ribs 221 on the side facing the sliding door 10. The length of the rib 221 located in the middle position is shorter than the length of the remaining two ribs 221, so as to adapt to the convex and concave surfaces of the sliding door 10, and so that all three ribs 221 abut against the limiting mating surface of the sliding door. Of course, in some other embodiments, the number of ribs 221 is not limited to three, and the specific length of the multiple ribs 221 depends on the limiting mating surface of the sliding door. Those skilled in the art can set the length of multiple ribs according to actual needs, all of which are covered within the protection scope of this application.
[0043] In one embodiment, the sliding door limiting assembly further includes a mounting base 30 installed on the sliding door mounting structure. The mounting base 30 includes a receiving cavity 31, in which the limiting block 20 is received. By providing the mounting base 30, it is convenient to install the limiting block 20 and protect the limiting block 20. On the other hand, the mounting block can be used to support the limiting block 20 and limit its engagement with the sliding door 10 in the open or closed position.
[0044] Specifically, the mounting base 30 has a semi-enclosed structure to form the aforementioned receiving cavity 31. The mounting base 30 is also provided with mounting holes 32 for connection with the sliding door mounting structure bolts 60 to improve installation efficiency.
[0045] like Figure 5 In the embodiment shown, Figure 5 for Figure 1 The diagram shows an exploded view of the structure. The mounting base 30 has a semi-enclosed structure, with openings in the X and Y directions. The limiting block 20 is positioned within the cavity defined by the semi-enclosed structure. The semi-enclosed structure extends along... Figure 5 Mounting plates extend vertically (Z-direction) from the mounting base 30, and each mounting plate has mounting holes 32 for screwing in bolts 60, thus facilitating the installation of the mounting base 30. Furthermore, to ensure the reliability of the mounting base 30, mounting holes 32 for screwing in bolts 60 are also provided on the base plate forming the semi-enclosed structure. As described above, the mounting base in this embodiment achieves connection by using three mounting holes for screwing in bolts 60. This installation method ensures installation strength and reliability while also facilitating disassembly and assembly by workers.
[0046] In one embodiment, the mounting base 30 further includes a first opening and a second opening communicating with the receiving cavity 31. In the open position, the first limiting part 21 engages with the sliding door 10 at the first opening, and in the closed position, the second limiting part 22 engages with the sliding door 10 at the second opening. Thus, when the sliding door 10 needs to be limited, the limiting block 20 can engage normally with the sliding door 10 without being affected by the mounting base 30. Furthermore, when the limiting block 20 engages with the sliding door 10, regardless of whether it is in the closed or open position, the inner wall of the receiving cavity 31 can support the limiting block 20 against the force from the sliding door 10, thereby improving the reliability of the sliding door 10's limiting function.
[0047] In one embodiment, the limiting block 20 further includes a first locking portion 23 and a second locking portion 24, and the mounting base 30 further includes a first locking engagement portion and a second locking engagement portion 33, wherein the first locking portion 23 engages with the first locking engagement portion, and the second locking portion 24 engages with the second locking engagement portion 33.
[0048] In this configuration, the first engaging portion 23 and the first engaging mating portion generate a first engaging force, while the second engaging portion 24 and the second engaging mating portion 33 generate a second engaging force. The direction of the first engaging force is opposite to the direction of force on the first limiting portion 21, and the direction of the second engaging force is opposite to the direction of force on the second limiting portion 22. Thus, when the first limiting portion 21 and the second limiting portion 22 are subjected to force during the limiting engagement, the first engaging force and the second engaging force can support the first limiting portion 21 and the second limiting portion 22 to remain in the limiting position, thereby improving the reliability of the limiting action.
[0049] like Figure 4In the illustrated embodiment, the first engaging portion 23 is a slot, and the first engaging mating portion is a protrusion. The protrusion engages within the slot to form a first engaging force along the opening direction of the sliding door. The second engaging portion 24 is a strip, and the second engaging mating portion 33 is a hole. The strip passes through the hole to form a second engaging force perpendicular to the sliding door 10. It can be understood that the second limiting portion 22 and the sliding door 10 achieve a limiting engagement through a pressing force along the Y direction. The direction of the second engaging force is also Y-direction. Therefore, the second engaging force can support the limiting engagement of the second limiting portion 22 and the sliding door 10 in the closed position, improving the limiting reliability of the sliding door 10 in the closed position. Similarly, the first limiting portion 21 and the sliding door 10 achieve a limiting engagement through a pressing force along the opening direction of the sliding door (… Figure 2 The first locking force (as shown in the X direction) is a limiting fit, and the direction of the first locking force is also the opening direction of the sliding door. Therefore, the first locking force can support the limiting fit between the first limiting part 21 and the sliding door 10 in the open position, thereby improving the limiting reliability of the sliding door 10 in the open position.
[0050] For further information, please refer to the following: Figure 5 The locking strip includes a first end 241 and a second end 242. When the locking strip engages with the locking hole, the first end 241 engages with the locking hole, and the second end 242 extends out of the locking hole and extends in a direction away from the first end 241. Thus, when assembling the limiting block 20 and the mounting base 30, the second end 242 can be passed through the locking hole first, and then the worker can hold the second end 242 and pull it in a direction away from the first end 241 to engage with the locking hole. This design simplifies the installation of the limiting block 20 and the mounting base 30, avoiding overly complex parts and connections, making the assembly process more intuitive and easier to understand. Furthermore, it reduces the difficulty and complexity for workers during assembly, thereby improving the assembly efficiency of the limiting block and the mounting base.
[0051] Specifically, both the first end 241 and the second end 242 can have rectangular cross-sections, and the locking hole is also rectangular in shape. The cross-sectional dimension of the second end 242 is smaller than that of the first end 241, allowing the second end 242 to pass smoothly through the locking hole. The locking hole and the cross-sectional dimension of the second end 242 are matched to achieve a snap-fit engagement. In other embodiments, the shapes of the locking hole, the first end 241, and the second end 242 can be square, circular, trapezoidal, or other varied and irregular shapes. It is understood that in these embodiments, the second end 242 must be able to pass through the locking hole, and the locking hole and the first end 241 must be able to achieve a snap-fit engagement.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
