Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and more specifically, relates to a sliding door hinge mechanism and a vehicle. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important part of the sustainable development of the automotive industry.

[0003] Some vehicles use sliding doors, which are typically connected to the vehicle body via a hinge mechanism. The sliding door is guided by a guide rail within the hinge mechanism to open and close. Currently, one end of the guide rail in most hinge mechanisms is curved inwards towards the vehicle body, allowing the sliding door to move inwards to close or outwards to open when it reaches the desired position. However, this curved guide rail occupies a significant amount of space in the width direction of the vehicle. Utility Model Content

[0004] The purpose of this application is to provide a sliding door hinge mechanism and a vehicle to improve the problem in the related art where the curved guide rail of the sliding door hinge mechanism occupies a large amount of space in the width direction of the vehicle.

[0005] In a first aspect, embodiments of this application provide a sliding door hinge mechanism, including:

[0006] The guide rail extends along the first direction;

[0007] Linkage rod, used to connect sliding doors;

[0008] The support is slidably mounted on the guide rail, and the connecting rod is hinged to the support so that the connecting rod can be folded or unfolded relative to the guide rail.

[0009] A locking structure is used to lock the connecting rod in the deployed state as the support moves along the guide rail.

[0010] In the technical solution of this application embodiment, by hinged to the support and slidably mounted on the guide rail, the link can be folded and unfolded. A locking structure is set to lock the link in the unfolded state. Thus, during use, the distance between the sliding door and the vehicle body can be adjusted by switching the state of the link. In this way, a guide rail that extends in a straight line can be used without bending the end of the guide rail, thereby reducing the space occupied in the width direction of the vehicle.

[0011] In some embodiments, the connecting rod is provided with a locking hole, and the locking structure includes a locking pin and a guide member for guiding the locking pin in and out of the locking hole. The locking pin is mounted on a support, and the guide member is mounted on a guide rail.

[0012] The above technical solution guides the locking pin into the locking hole on the linkage to lock the linkage's position. It has a simple structure, is easy to manufacture, and can reduce the risk of sliding doors colliding with the vehicle body during use.

[0013] In some embodiments, the guide rail has opposing start and end ends, and the guide includes a first segment, a second segment, and a third segment arranged sequentially; the first segment is disposed near the start end for keeping the locking pin out of the lock hole; the second segment extends from the first segment toward the end end and toward the support for moving the locking pin in and out of the lock hole; the third segment extends from the second segment toward the end end for keeping the locking pin inserted into the lock hole.

[0014] The above technical solution sets the guide component into three segments: the first segment, the second segment, and the third segment. The structure is simple, easy to manufacture, and low in cost.

[0015] In some embodiments, the first segment is smoothly connected to the second segment; and / or, the second segment is smoothly connected to the third segment.

[0016] The above technical solution allows for a smooth transition from the first segment to the second segment, facilitating the movement of the locking pin between the two segments. Similarly, a smooth transition from the second segment to the third segment facilitates the movement of the locking pin between the two segments.

[0017] In some embodiments, the support is provided with a first elastic element, which is used to push the locking pin in the direction of the guide element.

[0018] The above technical solution uses a first elastic element to push the locking pin in the direction of the guide element, which facilitates the locking pin to hold the guide element so that when the support moves from the second section to the first section, the locking pin can be pushed out of the lock hole. The structure is simple and easy to manufacture.

[0019] In some embodiments, a support plate is provided on one side of the connecting rod, and a lock hole is provided on the support plate.

[0020] The above technical solution involves setting a support plate on the connecting rod and setting a lock hole on the support plate, which facilitates the processing and manufacturing of the lock hole and the layout of the lock hole.

[0021] In some embodiments, the sliding door hinge mechanism includes a locking structure for locking the support in a first position, which is the position of the support when the link is in a folded state.

[0022] By using the above technical solution, a locking structure is set to lock the support in the first position so that the sliding door can be locked in the closed position during use, so as to facilitate the closing or opening of the sliding door.

[0023] In some embodiments, the support is provided with a stop bar, and the locking structure includes a locking block and a locking assembly of the locking block. The locking block is rotatably mounted on the guide rail, and a groove is provided on the locking block for the stop bar to be inserted. The locking assembly is mounted on the guide rail.

[0024] The above technical solution involves setting a groove on the locking block so that the stop bar is placed in the groove, allowing the locking block to stop the stop bar; the locking block is rotatably mounted on the guide rail so that the locking block can be rotated so that the stop bar can slide out of the groove of the locking block, allowing the support to move along the guide rail; and a locking assembly is provided to lock the angle of the locking block so as to lock the stop bar, thereby locking the position of the support.

[0025] In some embodiments, the locking assembly includes a locking protrusion that is elastically mounted on a guide rail, and a first locking groove on the locking block; when the locking protrusion is placed in the first locking groove, the angle of the locking block is locked, and the depth direction of the groove is set at an angle with the first direction; the connecting rod is provided with an unlocking structure for pushing the locking protrusion out of the first locking groove.

[0026] The above technical solution involves setting a first slot on the lock block and setting a protrusion to insert into the first slot to lock the angle of the lock block. The structure is simple, easy to process and manufacture, and can stably lock the angle of the lock block. An unlocking structure is set to allow the protrusion to exit the first slot, thereby unlocking the lock block so that the lock block can rotate and the support can move along the guide rail.

[0027] In some embodiments, the unlocking structure includes a top block for pushing the top latch out of the first slot when the link rotates from a folded state to an unfolded state, the top block being mounted on the link.

[0028] The above technical solution involves setting a top block on the connecting rod to push the top block out of the first slot, thereby unlocking the angle of the locking block. The structure is simple and easy to manufacture and assemble.

[0029] In some embodiments, a pressure plate is provided on one side of the connecting rod, and a top block is provided on the pressure plate.

[0030] The above technical solution involves setting a pressure plate and placing the top block on the pressure plate, which facilitates the positional layout of the top block and allows for proper pushing and locking of the protrusion.

[0031] In some embodiments, the locking block is provided with a second slot; when the protrusion is placed in the second slot, the angle of the locking block is locked and the depth direction of the groove is aligned with the first direction; the unlocking structure is also used to push the protrusion out of the second slot during the process of the support moving to the first position.

[0032] By using the above technical solution, a second slot is provided on the locking block, so that the locking block is locked in the second slot, and the depth direction of the groove is consistent with the first direction. Thus, when the support moves the stop rod out of the groove, the angle of the locking block can remain unchanged, so that when the support moves back, it can drive the stop rod into the groove.

[0033] In some embodiments, the locking assembly includes a support rod rotatably mounted on a guide rail and a second elastic member that elastically pushes the support rod toward the locking block side, with the locking protrusion extending onto the support rod.

[0034] The above technical solution uses a support rod to support the locking protrusion, which facilitates the support and installation of the locking protrusion. A second elastic element is set to push the support rod, so as to elastically push the locking protrusion towards the locking block. The structure is simple and easy to assemble.

[0035] In some embodiments, the support rod is provided with a protrusion for the unlocking structure to push against. One end of the support rod is rotatably connected to the guide rail. The locking protrusion and the protrusion are located on the same side of the connection between the support rod and the guide rail. The protrusion is provided to protrude from the side of the support rod toward the unlocking structure.

[0036] The above technical solution involves setting a protrusion on the support rod to unlock the structure and push it up, thereby moving the support rod and the locking protrusion, which facilitates operation. Positioning the locking protrusion and the protrusion on the same side of the connection between the support rod and the guide rail facilitates layout and assembly.

[0037] In some embodiments, the protrusion is located at the other end of the support rod, and the locking protrusion is located in the middle region of the support rod.

[0038] The above technical solution facilitates the setting of the protrusion's position so that the unlocking structure can push the protrusion, and also makes it easier to set the position of the unlocking structure.

[0039] In some embodiments, the side of the protrusion facing the other end of the support rod has a guide ramp.

[0040] The above technical solution provides a guide slope on the protrusion, which facilitates the unlocking structure to move away from the protrusion and cause the support rod to spring back, or to move onto the protrusion to press against the protrusion to unlock.

[0041] In some embodiments, the locking structure includes a support plate, a locking block and a locking assembly, all mounted on the support plate, which is mounted on a guide rail.

[0042] By using the above technical solution, a support plate is set up to support the lock block and the locking assembly, which allows for the separate assembly of the locking structure and then the whole assembly is installed on the guide rail, which facilitates assembly.

[0043] In some embodiments, the sliding door hinge mechanism further includes a first stop structure mounted on one end of the guide rail for limiting the support from moving to a position at one end of the guide rail; and / or, the sliding door hinge mechanism further includes a second stop structure mounted on the other end of the guide rail for limiting the support from moving to a position at the other end of the guide rail.

[0044] The above technical solution allows the first stop structure to limit the movement of one end of the support guide rail. A second stop structure can be used to limit the movement of the other end of the support guide rail.

[0045] In some embodiments, the guide rail is provided with a slide groove extending in a first direction, the two side walls of the slide groove are an upper side wall and a lower side wall, and a guide portion is provided on the upper side wall; a bearing wheel is installed on the support, the bearing wheel is placed in the slide groove and supported on the lower side wall, and a guide structure is installed on the support, the guide structure being slidably installed on the guide portion.

[0046] The above technical solution involves installing a bearing wheel on the support to support the support on the guide rail and allow the support to move flexibly along the guide rail; a guide part is installed on the upper side wall, and a guide structure is installed on the support to guide the support to move flexibly along the guide rail, thereby reducing the risk of the bearing wheel detaching from the slide groove.

[0047] Secondly, embodiments of this application provide a vehicle including a sliding door hinge mechanism as described above.

[0048] The above description is only an overview of the technical solution of this application.

[0069] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0070] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0071] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0072] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0073] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0074] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces). "Several" means one or more, unless otherwise explicitly specified.

[0075] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0076] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

For example, among three components A1, A2, and B, the distance between A1 and B is greater than the distance between A2 and B. Therefore, A2 is closer to B than A1, meaning A2 is adjacent to B, or B is adjacent to A2. Similarly, when there are multiple components C, namely C1, C2, ..., C... N If one of the C components, such as C2, is closer to the B component than the other C components, then B is adjacent to C2, or C2 is adjacent to B.

[0079] As vehicles evolve, users are demanding higher levels of comfort in their driving experience. Sliding doors are doors that move smoothly on a vehicle, taking up minimal space on the side of the vehicle when open, making it easier for users to get in and out, and are therefore widely used in many vehicles.

[0080] Sliding doors are typically connected to the vehicle body via a hinge mechanism. This mechanism generally includes a guide rail and a support that slides along the rail. The support is hinged to the sliding door, and its movement along the rail opens and closes the door. However, this type of hinge mechanism requires the front end of the guide rail to bend inwards towards the vehicle body. This allows the support to move forward, closing the door inwards. Conversely, as the support moves from the front to the rear of the guide rail, it gradually moves outwards, moving the door to the outside of the vehicle body before moving backwards to open it. This hinge mechanism, because the guide rail needs to bend inwards, occupies a significant amount of space in the vehicle's width direction, affecting the layout of other components. Especially for new energy vehicles, the bent guide rail often encroaches on the installation space for the battery pack, making battery placement difficult or limiting the use of smaller battery packs and reducing battery capacity.

[0081] Based on the above considerations, and to address the issue of the curved guide rail design in related technologies for sliding door hinge mechanisms occupying significant space in the vehicle's width direction, this application provides a sliding door hinge mechanism. This mechanism utilizes a connecting rod to connect the sliding door, with the connecting rod hinged to a support. The support is slidably mounted on a guide rail, allowing the connecting rod and support to move along the guide rail. The connecting rod can also rotate on the support, either towards the guide rail (in a folded state) or away from the guide rail (in an unfolded state). This folded state, when the connecting rod supports the sliding door, minimizes the distance between the sliding door and the guide rail. In the unfolded state, the distance between the sliding door and the guide rail increases. When the sliding door is at the doorway, the linkage can be rotated to fold, moving the door towards the vehicle to close it. Once closed, the door can be pushed outwards to unfold the linkage, moving the door to the outside of the vehicle and allowing it to move along the guide rail to open. This allows the use of a straight guide rail, eliminating the need for bending and reducing the space occupied in the vehicle's width direction. A locking mechanism locks the linkage in the unfolded state as the support moves along the guide rail, ensuring the sliding door remains locked to the outside of the vehicle during movement.

[0082] The technical solutions described in the embodiments of this application are applicable to various devices that use sliding doors, such as automobiles, subways, platform screen doors, ships, and other occasions or equipment where sliding doors can be used.

[0083] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 100 provided in some embodiments of this application. The vehicle 100 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicle 100 includes a body 110 and a chassis 120. The body 110 is connected to the chassis 120 and is mounted on the chassis 120, providing driving and passenger space, and protecting power components, electrical components, etc., on the chassis 120. Furthermore, the body 110 and chassis 120 can be manufactured separately to facilitate processing and manufacturing, reduce the manufacturing difficulty of the vehicle 100, and facilitate assembly, improving assembly efficiency.

[0084] The vehicle 100 has a battery device 121 installed inside, which may be located at the bottom, front, or rear of the vehicle 100. The battery device 121 can be used to power the vehicle 100; for example, it can serve as the vehicle 100's operating power source. The vehicle 100 may also include a controller 123 and a motor 122. The controller 123 controls the battery device 121 to supply power to the motor 122, for example, to meet the power needs of the vehicle 100 during starting, navigation, and driving.

[0085] In some embodiments, the battery device 121 can not only serve as the operating power source for the vehicle 100, but also as the driving power source for the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0086] In some embodiments, the battery device 121 may be integrated into the chassis 120 to improve the integration of the chassis 120. In some embodiments, the battery device 121 may also be installed in the vehicle body 110.

[0087] In some embodiments, the motor 122 may be integrated into the chassis 120 to improve the integration of the chassis 120.

[0088] In some embodiments, the controller 123 may be integrated into the chassis 120 to improve the integration of the chassis 120. In some embodiments, the controller 123 may also be installed in the body 110.

[0089] Please see Figure 1In some embodiments, the vehicle 100 has multiple orientations, including up, down, front, rear, left, and right, all of which are based on the orientation of the vehicle 100. That is, the direction from the front to the rear of the vehicle is the front-to-back direction, the direction from the roof to the bottom of the vehicle is the top-to-bottom direction, and the driver's seat and passenger seat are arranged in a left-right direction. For example, the front-to-back direction of the vehicle 100 is also called the length direction, which is the X direction; the left-to-right direction of the vehicle 100 is also called the width direction, which is the Y direction; and the height direction of the vehicle 100 is also called the vertical direction, which is the Z direction. Accordingly, in the forward-backward direction (X) of vehicle 100, the forward direction refers to the direction vehicle 100 faces forward, i.e., forward is the F direction; the backward direction refers to the direction vehicle 100 faces rearward, i.e., rear is the B direction. In the left-right direction (Y) of vehicle 100, the right direction refers to the direction vehicle 100 faces to the right, i.e., right is the R direction; the left direction refers to the direction vehicle 100 faces to the left, i.e., left is the L direction. In the height direction (Z) of vehicle 100, the upward direction refers to the direction vehicle 100 faces upward, i.e., upward is the U direction; the downward direction refers to the direction vehicle 100 faces downward, i.e., downward is the D direction. The directions of chassis 120 are consistent with those of vehicle 100. The directions of body 110 are consistent with those of vehicle 100.

[0090] In some embodiments, please refer to Figure 1 The vehicle body 110 is provided with a doorway 1101, which is an opening or doorway structure on the vehicle body 110 for users to enter and exit the vehicle 100. A sliding door 111 is installed on the vehicle body 110, which is used to close at the doorway 1101 to achieve door closure. The sliding door 111 is installed on the vehicle body 110 via a sliding door hinge mechanism 20, which supports and guides the movement of the sliding door 111.

[0091] Please see Figures 1 to 12 According to some embodiments of this application, this application provides a sliding door hinge mechanism 20, including a guide rail 21, a connecting rod 22, a support 23, and a locking structure 24; the guide rail 21 extends along a first direction; the connecting rod 22 is used to connect to the sliding door 111; the support 23 is slidably mounted on the guide rail 21, and the connecting rod 22 is hinged to the support 23 so that the connecting rod 22 is folded or unfolded relative to the guide rail 21; the locking structure 24 is used to lock the connecting rod 22 in the unfolded state during the movement of the support 23 along the guide rail 21.

[0092] The guide rail 21 is a mechanical element used to guide and support moving parts. It is usually installed on mechanical equipment or structures to ensure that the moving parts can move smoothly and accurately along a predetermined path. The guide rail 21 can be made of materials such as steel or aluminum alloy. The guide rail 21 can be shaped like a rod or a strip. Of course, a groove structure can also be provided in the guide rail 21 to serve as a slide, thereby positioning and supporting the support 23, facilitating the movement of the support 23 along the guide rail 21. The first direction is the direction along the length of the guide rail 21. Since the guide rail 21 guides the movement of the sliding door 111, the first direction is also the direction in which the sliding door 111 moves. When the sliding door hinge mechanism 20 is applied to the vehicle 100 and the sliding door 111 moves back and forth, the first direction is generally the back and forth direction of the vehicle 100.

[0093] Link 22 refers to a rod-shaped or strip-shaped structural component of a certain length used to connect two objects. Link 22 can be made of materials such as steel or aluminum alloy. When link 22 is used to connect the sliding door 111, it means that the sliding door 111 is connected to link 22, which drives the sliding door 111 to move, and also provides some support to the sliding door 111.

[0094] Support 23 refers to the structure that supports connecting rod 22, which is used to connect to sliding door 111, thereby providing some support to sliding door 111 via support 23. Support 23 is slidably mounted on guide rail 21, meaning that support 23 is installed on guide rail 21 and can move along guide rail 21. The movement of support 23 along guide rail 21 drives connecting rod 22 to move along guide rail 21, thus guiding the movement of sliding door 111 during use.

[0095] As an example, a slider can be provided on the support 23 and mounted on the guide rail 21 to allow the support 23 to slide on the guide rail 21. As an example, a roller can be provided on the support 23 and mounted on the guide rail 21 to allow the support 23 to slide on the guide rail 21. As an example, if the guide rail 21 is a strip, a groove or hole can be provided on the support 23 to fit onto the guide rail 21, allowing the support 23 to slide on the guide rail 21. As an example, if the guide rail 21 has a groove structure, the support 23 can have a sliding part adapted to be disposed in the groove structure, so that the sliding part is placed in the groove structure, allowing the support 23 to slide on the guide rail 21.

[0096] A hinge is a connection between two or more objects that is linked together by a specific point or area of ​​connection, allowing these objects to move relative to each other to a certain extent around that point. For example, a hinged connection could be achieved by connecting two objects rotatably via a shaft. Another example is a hinged connection, where two objects are rotatably connected via a hinge. Yet another example is a hinged connection, where two objects are connected via a universal joint.

[0097] The connecting rod 22 is hinged to the support 23, so that the support 23 can drive the connecting rod 22 to move and support the connecting rod 22 to a certain extent. The connecting rod 22 can rotate relative to the support 23, thereby allowing the connecting rod 22 to rotate relative to the guide rail 21.

[0098] Folding or unfolding link 22 relative to guide rail 21 means that link 22 rotates on support 23 such that the end of link 22 away from support 23 moves towards guide rail 21. The state where link 22 is in the folded state is when the end of link 22 away from support 23 is closest to guide rail 21. Conversely, rotating link 22 on support 23 such that the end of link 22 away from support 23 moves away from guide rail 21 is in the unfolded state, when the distance between the end of link 22 away from support 23 and guide rail 21 is maximized. In other words, folding or unfolding link 22 relative to guide rail 21 means that link 22 can be in a folded state or an unfolded state relative to guide rail 21.

[0099] Locking structure 24 refers to a structure that can lock the connecting rod 22, keeping it in the extended state. As an example, locking structure 24 can be a snap-fit ​​structure, locking the connecting rod 22 to keep it in the extended state. As another example, locking structure 24 can be a spring-loaded ball, using the spring-loaded ball to hold the connecting rod 22 in place, locking it in the extended state. A spring-loaded ball is a mechanical component commonly used to connect, fix, or adjust parts in equipment. A spring-loaded ball generally consists of a bead-like structure made of elastic metal or plastic, capable of clamping, positioning, or releasing through compression or extension. A spring-loaded ball typically includes a ball body, an elastic element, and a base; the ball body is the main load-bearing part, often spherical or hemispherical in shape; the elastic element provides elastic support, allowing the ball body to rebound under pressure; common materials include spring steel, stainless steel, or highly elastic plastics; the base is used to fix the position of the spring-loaded ball, preventing it from shifting during use. The spring-loaded ball provides support through its internal elastic element. When an external force is applied to the bead, the elastic element is compressed, and the bead contracts inward; when the external force is removed, the elastic element returns to its original shape, and the bead pops out again and locks into the predetermined position.

[0100] In the technical solution of this application embodiment, by hinged link 22 to support 23 and slidably mounted support 23 on guide rail 21, link 22 can be folded and unfolded. Locking structure 24 is provided to lock link 22 in unfolded state. Thus, in use, the distance between sliding door 111 and vehicle body 110 can be adjusted by switching the state of link 22. In this way, a straight-extending guide rail 21 can be used without bending the end of the guide rail 21, thereby reducing the space occupied in the width direction of vehicle 100.

[0101] In some embodiments, please refer to Figures 3 to 5 , Figure 10 and Figure 12 The connecting rod 22 is provided with a locking hole 2211. The locking structure 24 includes a locking pin 241 and a guide 242 that guides the locking pin 241 in and out of the locking hole 2211. The locking pin 241 is installed on the support 23 and the guide 242 is installed on the guide rail 21.

[0102] The lock hole 2211 refers to a hole structure provided on the connecting rod 22 into which the locking pin 241 can be inserted. As an example, the lock hole 2211 can be directly provided on the main body of the connecting rod 22; that is, the hole structure is directly provided on the main body of the connecting rod 22. Alternatively, a protruding structure can be provided on the connecting rod 22, and the hole structure can be provided on this structure to form the lock hole 2211.

[0103] Locking pin 241 refers to the pin structure used to lock the connecting rod 22. Locking pin 241 can be cylindrical, elongated, or other shapes. Locking pin 241 can be made of materials with a certain strength, such as steel or aluminum alloy.

[0104] The guide 242 is a structural component that can guide or drive the locking pin 241 to move. The guide 242 can be a plate-shaped component, a rod-shaped component, or other structural components. The guide 242 guides the locking pin 241 in and out of the lock hole 2211. When the locking pin 241 is inserted into the lock hole 2211, the connecting rod 22 is locked in the unfolded state. When the locking pin 241 is removed from the lock hole 2211, the connecting rod 22 can rotate on the support 23.

[0105] Locking pin 241 is mounted on support 23 to be supported by support 23. Since locking pin 241 can enter lock hole 2211, it is movably mounted on support 23. As an example, a hole structure can be provided on support 23 to insert locking pin 241 into the hole structure, thus mounting locking pin 241 on support 23, and locking pin 241 can move axially to enter and exit lock hole 2211. As an example, a bushing can be provided on support 23, and locking pin 241 can be inserted into the bushing to allow locking pin 241 to enter lock hole 2211. As an example, locking pin 241 can also be mounted on support 23 by an elastic element so that locking pin 241 can enter and exit lock hole 2211. Locking pin 241 is installed on support 23. When locking pin 241 is inserted into locking hole 2211, it can remain inserted into locking hole 2211 during the movement of support 23 along guide rail 21, so that connecting rod 22 is locked in the unfolded state during the movement of support 23 along guide rail 21.

[0106] The above technical solution guides the locking pin 241 into the locking hole 2211 on the connecting rod 22 through the guide member 242, so as to lock the position of the connecting rod 22. The structure is simple and easy to process and manufacture. Moreover, it can reduce the risk of the sliding door 111 colliding with the vehicle body 110 during use.

[0107] In some embodiments, please refer to Figures 1 to 5 , Figure 8 , Figure 10 and Figure 12 The guide rail 21 has a starting end 2101 and a ending end 2102. The guide member 242 includes a first segment 2421, a second segment 2422 and a third segment 2423 arranged sequentially. The first segment 2421 is arranged near the starting end 2101 to keep the locking pin 241 out of the lock hole 2211. The second segment 2422 extends from the first segment 2421 toward the ending end 2102 and toward the support 23 to move the locking pin 241 in and out of the lock hole 2211. The third segment 2423 extends from the second segment 2422 toward the ending end 2102 to keep the locking pin 241 inserted into the lock hole 2211.

[0108] The starting end 2101 is one end of the guide rail 21, and the ending end 2102 is the other end of the guide rail 21. The starting end 2101 and the ending end 2102 are opposite ends in length of the guide rail 21. In application, the starting end 2101 is the end of the guide rail 21 where the support 23 is located when the sliding door 111 is in the closed state; the ending end 2102 is the end of the guide rail 21 where the support 23 is located when the sliding door 111 is in the fully open state.

[0109] The first segment 2421 is a region of the guide member 242 near the starting end 2101. The second segment 2422 is a region of the guide member 242 connected to the first segment 2421. The third segment 2423 is a region of the guide member 242 connected to the end of the second segment 2422 away from the first segment 2421.

[0110] The guide 242 includes a first segment 2421, a second segment 2422 and a third segment 2423 arranged in sequence, which divides the guide 242 into three segments in length, namely the first segment 2421, the second segment 2422 and the third segment 2423.

[0111] The first segment 2421 being positioned near the starting end 2101 means that the first segment 2421 is located at one end of the starting end 2101 of the guide rail 21.

[0112] The first segment 2421 is used to keep the locking pin 241 out of the lock hole 2211. This means that the support 23 moves to the starting end 2101 near the guide rail 21. Correspondingly, the first segment 2421 of the guide member 242 guides the locking pin 241 to be kept out of the lock hole 2211.

[0113] The second segment 2422 is extended from the first segment 2421 toward the end 2102 and the support 23. This means that the second segment 2422 is inclined in the first direction and extends inclinedly from the beginning 2101 toward the end 2102 and the support 23.

[0114] The second section 2422 is used to move the locking pin 241 in and out of the lock hole 2211. This means that the support 23 moves on the guide rail 21 within the corresponding area of ​​the second section 2422. Correspondingly, the locking pin 241 moves along the second section 2422. When the locking pin 241 moves from the third section 2423 towards the first section 2421 within the second section 2422, it causes the locking pin 241 to exit the lock hole 2211. When the locking pin 241 moves from the first section 2421 towards the third section 2423 within the second section 2422, it keeps the locking pin 241 inserted into the lock hole 2211.

[0115] The above technical solution sets the guide 242 into a first segment 2421, a second segment 2422, and a third segment 2423, which has a simple structure, is easy to manufacture, and has a low cost.

[0116] In some embodiments, the locking structure 24 includes a press-type elastic self-locking mechanism and a pressing member. The press-type elastic self-locking mechanism is mounted on a support 23, while the pressing member is mounted on a guide rail 21. The support 23 moves along the guide rail 21 from the starting end 2101 toward the ending end 2102. When passing the pressing member, the pressing member actuates the press-type elastic self-locking mechanism, causing the shaft of the press-type elastic self-locking mechanism to extend and insert into the lock hole 2211, thereby locking the connecting rod 22 in the extended state. The support 23 moves along the guide rail 21 from the ending end 2102 toward the starting end 2101. When passing the pressing member, the pressing member actuates the press-type elastic self-locking mechanism, causing the shaft of the press-type elastic self-locking mechanism to retract and exit the lock hole 2211, allowing the connecting rod 22 to rotate relative to the support 23. The press-type elastic self-locking mechanism can be a press-to-release self-locking structure similar to a ball pen, or a press-to-locking structure similar to a self-locking switch. A pressing component refers to a structural component that can actuate a press-type elastic self-locking mechanism. Pressing components can be block-shaped, plate-shaped, or rod-shaped, etc.

[0117] In some embodiments, please refer to Figures 3 to 5 , Figure 10 and Figure 12 The first segment 2421 and the second segment 2422 are smoothly connected.

[0118] The smooth transition between the first segment 2421 and the second segment 2422 means that the connection between the first segment 2421 and the second segment 2422 is arc-shaped or curved, so that there are no sharp edges between the first segment 2421 and the second segment 2422, allowing the locking pin 241 to move flexibly between the first segment 2421 and the second segment 2422.

[0119] The above technical solution allows for a smooth transition from the first segment 2421 to the second segment 2422, facilitating the movement of the locking pin 241 between the first segment 2421 and the second segment 2422.

[0120] In some embodiments, the second segment 2422 and the third segment 2423 are smoothly connected.

[0121] The smooth transition between the second segment 2422 and the third segment 2423 means that the connection between the second segment 2422 and the third segment 2423 is arc-shaped or curved, so that there are no sharp edges between the second segment 2422 and the third segment 2423, allowing the locking pin 241 to move flexibly between the second segment 2422 and the third segment 2423.

[0122] The above technical solution allows for a smooth transition from the second segment 2422 to the third segment 2423, facilitating the movement of the locking pin 241 between the second segment 2422 and the third segment 2423.

[0123] In some embodiments, the first segment 2421 is smoothly connected to the second segment 2422, and the second segment 2422 is smoothly connected to the third segment 2423, so that the guide 242 guides the locking pin 241 to move smoothly.

[0124] In some embodiments, please refer to Figures 3 to 5 , Figure 10 and Figure 12 The support 23 is provided with a first elastic element 243, which is used to push the locking pin 241 in the direction of the guide 242.

[0125] The first elastic element 243 refers to a structural element with elasticity, such as a spring, a sheet, a bellows, etc.

[0126] By using the above technical solution, the first elastic member 243 is set to push the locking pin 241 in the direction of the guide member 242, which makes it easier for the locking pin 241 to hold the guide member 242, so that when the support 23 moves from the second section 2422 to the first section 2421, the locking pin 241 can be pushed out of the lock hole 2211. The structure is simple and easy to manufacture.

[0127] In some embodiments, the guide 242 may be a plate-shaped member, and the first elastic member 243 pushes the locking pin 241 against the plate-shaped guide 242 so that the support 23 moves along the guide rail 21, and the plate-shaped guide 242 presses against the locking pin 241, so that the locking pin 241 moves in and out of the lock hole 2211.

[0128] In some embodiments, the guide member 242 is a plate-shaped member, and a slide hole can be provided on the guide member 242. The locking pin 241 is slidably placed in the slide hole, so that as the support 23 moves along the guide rail 21, the locking pin 241 is driven to enter and exit the locking hole 2211 through the side wall of the slide hole.

[0129] In some embodiments, the guide member 242 uses a rod-shaped member, and a ring can be provided on the locking pin 241 to fit onto the rod-shaped member, so that as the support 23 moves along the guide rail 21, the locking pin 241 is driven to move in and out of the lock hole 2211 by the rod-shaped member.

[0130] In some embodiments, please refer to Figures 3 to 5 , Figure 8 , Figure 10 and Figure 12A ball bearing 244 is mounted on one end of the locking pin 241 near the guide member 242. The ball bearing 244 abuts against the guide member 242 to slide flexibly on the guide member 242, thereby facilitating the guide member 242 to press the locking pin 241 into and out of the lock hole 2211. As an example, a ball socket can be provided on the locking pin 241, and the ball bearing 244 can be installed in the ball socket to achieve the installation of the ball bearing 244 on the locking pin 241. As an example, a ball seat 245 can be installed on the locking pin 241 to install the ball bearing 244 on the locking pin 241.

[0131] In some embodiments, please refer to Figures 3 to 5 , Figure 8 , Figure 10 and Figure 12 A support plate 221 is provided on one side of the connecting rod 22, and a lock hole 2211 is provided on the support plate 221.

[0132] Support plate 221 refers to the plate extending from connecting rod 22. Support plate 221 can be made of materials such as steel and aluminum alloy. Of course, support plate 221 can also be made of materials such as rigid plastic, ceramic, and carbon fiber. As an example, support plate 221 and connecting rod 22 can be integrally formed, that is, a plate-like part extends from connecting rod 22 to form support plate 221. As an example, support plate 221 can also be made separately and then welded or fixed to connecting rod 22 with fasteners.

[0133] The lock hole 2211 is provided on the support plate 221, which means that the support plate 221 has a hole structure to serve as the lock hole 2211. Providing the lock hole 2211 on the support plate 221 facilitates processing and manufacturing, and also facilitates the placement of the lock hole 2211.

[0134] Through the above technical solution, a support plate 221 is set on the connecting rod 22, and a lock hole 2211 is set on the support plate 221, which facilitates the processing and manufacturing of the lock hole 2211 and the position layout of the lock hole 2211.

[0135] In some embodiments, a lock hole 2211 may also be provided directly on the connecting rod 22.

[0136] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The sliding door hinge mechanism 20 includes a locking structure 25 for locking the support 23 in a first position, which is the position of the support 23 when the connecting rod 22 is in a folded state.

[0137] The locking structure 25 refers to a structure used to lock the support 23 in position on the guide rail 21. As an example, the locking structure 25 can use a snap-fit, which engages the support 23 when it moves to the first position, thus locking the support 23 in that position. Alternatively, the locking structure 25 can use a ball bearing, which abuts against the support 23 when it moves to the first position, thus locking the support 23 in that position.

[0138] The first position is the position of the support 23 when the connecting rod 22 is in the folded state. When the support 23 moves to the guide rail 21 near its starting end 2101, the connecting rod 22 will rotate to the folded state. Therefore, the first position is the position on the guide rail 21 near the starting end 2101.

[0139] By using the above technical solution, a locking structure 25 is set to lock the support 23 in the first position so that the sliding door 111 can be locked in the closed position during use, so as to facilitate the closing or opening of the sliding door 111.

[0140] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The support 23 is provided with a stop bar 233. The locking structure 25 includes a locking block 251 and a locking assembly 252 for locking the locking block 251. The locking block 251 is rotatably mounted on the guide rail 21. The locking block 251 has a groove 2511 for the stop bar 233 to be inserted into. The locking assembly 252 is mounted on the guide rail 21.

[0141] The stop bar 233 refers to a rod-shaped or column-shaped structural component. The stop bar 233 can be made of materials such as steel or aluminum alloy. Alternatively, it can be made of materials such as rigid plastic, ceramic, or carbon fiber. As an example, the stop bar 233 and the support 23 can be integrally molded. Alternatively, the stop bar 233 can be manufactured separately and then welded or fixed to the support 23 using fasteners.

[0142] Locking block 251 refers to a block-shaped component that can move the stop lever 233 to lock the support 23 in position. Locking block 251 can be made of materials such as steel and aluminum alloy. Of course, locking block 251 can also be made of materials such as hard plastic, ceramic, and carbon fiber.

[0143] The locking block 251 is rotatably mounted on the guide rail 21, meaning that the locking block 251 is mounted on the guide rail 21 and can rotate on the guide rail 21. As an example, the locking block 251 can be rotatably mounted on the guide rail 21 via a shaft. As an example, the locking block 251 can be rotatably mounted on the guide rail 21 via a hinge.

[0144] The groove 2511 refers to the groove structure provided on the locking block 251. The groove 2511 is provided on the locking block 251 so that when the stop rod 233 is placed in the groove 2511, the stop rod 233 is limited, thereby locking the support 23.

[0145] The locking assembly 252 refers to a structure used to lock the locking block 251 to prevent its rotation. The locking assembly 252 is mounted on a guide rail 21 for support. As an example, the locking assembly 252 can use a pin, with a corresponding locking hole on the locking block 251. The pin is placed in the locking hole to lock the locking block 251. This type of locking assembly 252 can limit the rotation of the locking block 251 to a certain extent, but under external force, it can also push the pin out of the locking hole, allowing the locking block 251 to rotate. As an example, the locking assembly 252 can use an elastic block to block the locking block 251, thus limiting its rotation. This type of locking assembly 252 can also limit the rotation of the locking block 251 to a certain extent, but under external force, it can also push the locking block 251 away from the elastic block, allowing it to rotate.

[0146] The support 23 slides on the guide rail 21, causing the stop bar 233 to move along the guide rail 21. As the support 23 moves toward the first position, the stop bar 233 enters the groove 2511. During the movement of the support 23 to the first position, the stop bar 233 pushes the side wall of the groove 2511. Since the locking block 251 is rotatably mounted on the guide rail 21, it can be pushed to rotate until the locking assembly 252 locks the locking block 251, thus restricting its rotation. The support 23 then reaches the first position. To move the support 23 away from the first position, the support 23 is moved, forcing the stop bar 233 to push the locking block 251 to rotate and disengage from the locking assembly 252, so that the stop bar 233 leaves the groove 2511, allowing the support 23 to move along the guide rail 21 and leave the first position.

[0147] Through the above technical solution, a groove 2511 is provided on the locking block 251, so that the stop bar 233 is placed in the groove 2511, so that the locking block 251 blocks the stop bar 233; the locking block 251 is rotatably mounted on the guide rail 21, so that the locking block 251 can be rotated so that the stop bar 233 can slide out of the groove 2511 of the locking block 251, so that the support 23 can move along the guide rail 21; and a locking assembly 252 is provided to lock the angle of the locking block 251 to lock the stop bar 233, thereby locking the position of the support 23.

[0148] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11The locking assembly 252 includes a locking protrusion 2522, which is elastically mounted on the guide rail 21. The locking block 251 is provided with a first locking groove 2512. When the locking protrusion 2522 is placed in the first locking groove 2512, the angle of the locking block 251 is locked, and the depth direction of the groove 2511 is set at an angle with the first direction. The connecting rod 22 is provided with an unlocking structure 26 for pushing the locking protrusion 2522 out of the first locking groove 2512.

[0149] The latching protrusion 2522 refers to a block-shaped or protruding structure that can hold the locking block 251. The latching protrusion 2522 can be a protruding structure provided on a plate, rod, or other structure to facilitate its support and installation. The latching protrusion 2522 can also be fixed to an elastic element, which supports the latching protrusion 2522.

[0150] The phrase "the latch 2522 is elastically mounted on the guide rail 21" means that the latch 2522 is supported on the guide rail 21 and can move elastically relative to the guide rail 21. As an example, the latch 2522 can be mounted on an elastic element, which is then mounted on the guide rail 21, thus achieving elastic mounting of the latch 2522 on the guide rail 21. The elastic element can be a spring, a spring sheet, a rubber block, etc. As another example, the latch 2522 can be slidably mounted on the guide rail 21, and an elastic element can be provided on the guide rail 21 to elastically push the latch 2522 towards the locking block 251, thereby achieving elastic mounting of the latch 2522 on the guide rail 21.

[0151] The first slot 2512 refers to the slot structure provided on the locking block 251. The first slot 2512 can be provided on the peripheral side of the locking block 251. The first slot 2512 can also be provided on the side of the locking block 251.

[0152] With the protrusion 2522 positioned in the first slot 2512, the angle of the locking block 251 is locked, and the depth direction of the groove 2511 is set at an angle to the first direction. That is, when the protrusion 2522 is inserted into the first slot 2512, the locking block 251 is locked in position by the cooperation between the protrusion 2522 and the first slot 2512, thus restricting the rotation of the locking block 251. The depth direction of the groove 2511 is set at an angle to the first direction, that is, the depth direction of the groove 2511 is not parallel to the first direction. In this way, when the stop bar 233 is located in the groove 2511, the risk of the stop bar 233 falling out of the groove 2511 can be effectively reduced, thereby locking the position of the support 23.

[0153] The unlocking structure 26 refers to a structure that can push the latching protrusion 2522 away from the locking block 251. The unlocking structure 26 is provided on the connecting rod 22. The unlocking structure 26 on the connecting rod 22 for pushing the latching protrusion 2522 out of the first slot 2512 means that the unlocking structure 26 is located on the connecting rod 22, allowing the connecting rod 22 to move and rotate the unlocking structure 26. When the connecting rod 22 rotates to the unfolded state, it can drive the unlocking structure 26 to rotate, causing the unlocking structure 26 to push the latching protrusion 2522 out of the first slot 2512, so that the support 23 can move, allowing the stop rod 233 to drive the locking block 251 to rotate. The unlocking structure 26 can be a rod-shaped, block-shaped, or plate-shaped component provided on the connecting rod 22; any structure that allows the latching protrusion 2522 to move only when the connecting rod 22 rotates to the unfolded state is sufficient.

[0154] The above technical solution provides a first slot 2512 on the locking block 251 and a protrusion 2522 to be inserted into the first slot 2512 to lock the angle of the locking block 251. The structure is simple, easy to manufacture, and can stably lock the angle of the locking block 251. An unlocking structure 26 is provided to allow the protrusion 2522 to exit the first slot 2512, thereby unlocking the locking block 251 so that the locking block 251 can rotate, and the support 23 can move along the guide rail 21.

[0155] In some embodiments, when the latching protrusion 2522 is placed in the first latching groove 2512, the angle of the locking block 251 is locked, and the depth direction of the groove 2511 is set perpendicular to the first direction so that the locking block 251 can better lock the stop bar 233.

[0156] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The unlocking structure 26 includes a top block 261 for pushing the top latch 2522 out of the first latch 2512 when the link 22 is rotated from the folded state to the unfolded state. The top block 261 is mounted on the link 22.

[0157] Top block 261 refers to a block-shaped component installed on connecting rod 22. Top block 261 can be directly installed on connecting rod 22, or indirectly installed on connecting rod 22 through supporting structural components.

[0158] The top block 261 is used to push the locking protrusion 2522 out of the first slot 2512 when the connecting rod 22 rotates from the folded state to the unfolded state. This means that the connecting rod 22 rotates to the unfolded state, so as to drive the top block 261 to rotate and push the locking protrusion 2522 to move out of the first slot 2512, thereby unlocking the locking block 251 so that the locking block 251 can rotate.

[0159] The above technical solution involves setting a top block 261 on the connecting rod 22 to push the top protrusion 2522 out of the first slot 2512, thereby unlocking the angle of the locking block 251. The structure is simple and easy to manufacture and assemble.

[0160] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 A pressure plate 262 is provided on one side of the connecting rod 22, and a top block 261 is provided on the pressure plate 262.

[0161] Pressure plate 262 refers to a plate extending from connecting rod 22. Pressure plate 262 can be made of materials such as steel or aluminum alloy. Of course, pressure plate 262 can also be made of materials such as rigid plastic, ceramic, or carbon fiber. As an example, pressure plate 262 and connecting rod 22 can be integrally molded, meaning that a plate-like component extends from connecting rod 22 to form pressure plate 262. As an example, pressure plate 262 can also be manufactured separately and then welded or fixed to connecting rod 22 using fasteners.

[0162] The top block 261 being provided on the pressure plate 262 means that the pressure plate 262 has a top block 261. As an example, the top block 261 and the pressure plate 262 can be integrally formed for ease of manufacturing. As an example, the top block 261 can also be manufactured separately and then welded or fixed to the pressure plate 262 using fasteners. Fasteners can be structural components such as screws and rivets.

[0163] Through the above technical solution, a pressure plate 262 is set and a top block 261 is placed on the pressure plate 262, which facilitates the position layout of the top block 261 so as to facilitate the movement of the push-top bracket 2522.

[0164] In some embodiments, when the connecting rod 22 is provided with a support plate 221 and a pressure plate 262, the support plate 221 can be fixedly connected to the pressure plate 262.

[0165] In some embodiments, when the support plate 221 is connected to the pressure plate 262, the lock hole 2211 can penetrate the pressure plate 262 to allow the locking pin 241 to enter and exit.

[0166] In some embodiments, the support plate 221 and the pressure plate 262 on the connecting rod 22 can be the same plate. That is, a plate is provided on the connecting rod 22, which serves as both the support plate 221 and the pressure plate 262.

[0167] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11The locking block 251 is provided with a second slot 2513; when the protrusion 2522 is placed in the second slot 2513, the angle of the locking block 251 is locked and the depth direction of the groove 2511 is consistent with the first direction; the unlocking structure 26 is also used to push the protrusion 2522 out of the second slot 2513 during the process of the support 23 moving to the first position.

[0168] The second slot 2513 refers to the slot structure provided on the locking block 251. The second slot 2513 can be provided on the peripheral side of the locking block 251. The second slot 2513 can also be provided on the side of the locking block 251.

[0169] With the protrusion 2522 positioned in the second slot 2513, the angle of the locking block 251 is locked, and the depth direction of the groove 2511 is aligned with the first direction. That is, when the protrusion 2522 is inserted into the second slot 2513, the locking block 251 is locked in position by the cooperation between the protrusion 2522 and the second slot 2513, thus restricting the rotation of the locking block 251. This allows the depth direction of the groove 2511 to be aligned with the first direction, so that the stop bar 233 can be moved out of the groove 2511, allowing the support 23 to move along the guide rail 21, or the support 23 to move toward the locking block 251, and the stop bar 233 to enter the groove 2511.

[0170] The unlocking structure 26 is also used to push the protrusion 2522 out of the second slot 2513 during the process of the support 23 moving to the first position. Then the support 23 moves towards the first position on the guide rail 21, and when the stop bar 233 enters the groove 2511, the unlocking structure 26 pushes the protrusion 2522 out of the second slot 2513 so that the locking block 251 can rotate. Thus, when the support 23 reaches the first position, the stop bar 233 drives the locking block 251 to rotate and causes the first slot 2512 of the locking block 251 to rotate to the position corresponding to the protrusion 2522. Then, when the connecting rod 22 rotates to the folded state, the protrusion 2522 can be placed in the first slot 2512.

[0171] Through the above technical solution, a second slot 2513 is provided on the locking block 251, so that the locking protrusion 2522 is placed in the second slot 2513 to lock the locking block 251 in the groove 2511. The depth direction is consistent with the first direction. So that when the support 23 drives the stop bar 233 to move out of the groove 2511, the angle of the locking block 251 can remain unchanged, so that when the support 23 moves back, it can drive the stop bar 233 into the groove 2511.

[0172] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11The locking assembly 252 includes a support rod 2521 rotatably mounted on the guide rail 21 and a second elastic member 2524 that elastically pushes the support rod 2521 toward the locking block 251. The locking protrusion 2522 is provided on the support rod 2521.

[0173] Support rod 2521 refers to the rod used to support the locking protrusion 2522. Support rod 2521 can be made of materials such as steel and aluminum alloy. Of course, support rod 2521 can also be made of materials such as rigid plastic, ceramic, and carbon fiber.

[0174] A latching protrusion 2522 is provided on the support rod 2521 to support the latching protrusion 2522 and to move the latching protrusion 2522. As an example, the latching protrusion 2522 and the support rod 2521 can be integrally formed, meaning that a protruding structure extends from the support rod 2521 to form the latching protrusion 2522. As an example, the support rod 2521 and the latching protrusion 2522 can also be manufactured separately and then welded or connected using fasteners.

[0175] The support rod 2521 is rotatably mounted on the guide rail 21, meaning that the support rod 2521 is mounted on the guide rail 21 and can rotate relative to the guide rail 21. The support rod 2521 can be rotatably mounted on the guide rail 21 through structures such as ball joints, shafts, and hinges.

[0176] The second elastic element 2524 refers to a structural component with elasticity. The second elastic element 2524 can be a spring, a sheet, an elastic rope, etc. The second elastic element 2524 elastically pushes the support rod 2521 towards the locking block 251, and elastically pushes the locking protrusion 2522 towards the locking block 251.

[0177] The above technical solution provides a support rod 2521 to support the latching protrusion 2522, facilitating the support and installation of the latching protrusion 2522. A second elastic element 2524 is provided to push the support rod 2521, thereby elastically pushing the latching protrusion 2522 toward the locking block 251. The structure is simple and easy to assemble.

[0178] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The support rod 2521 is provided with a protrusion 2523 for the unlocking structure 26 to push. One end of the support rod 2521 is rotatably connected to the guide rail 21. The locking protrusion 2522 and the protrusion 2523 are located on the same side of the connection between the support rod 2521 and the guide rail 21. The protrusion 2523 protrudes from the support rod 2521 toward the unlocking structure 26.

[0179] The protrusion 2523 refers to a block-shaped or convex structure that can be actuated by the unlocking structure 26. The support rod 2521 is provided with the protrusion 2523 so that the unlocking structure 26 can actuate, thereby pushing the support rod 2521 and the locking protrusion 2522 thereon to rotate. In some embodiments, the unlocking structure 26 can also directly push the support rod 2521 to rotate.

[0180] The rotatable connection between one end of the support rod 2521 and the guide rail 21 means that the connection point between the support rod 2521 and the guide rail 21 is located at one end of the support rod 2521. Accordingly, the support rod 2521 rotates around its connection point with the guide rail 21.

[0181] The locking protrusion 2522 and the protrusion 2523 are located on the same side of the connection between the support rod 2521 and the guide rail 21. Accordingly, the locking protrusion 2522 and the protrusion 2523 can rotate in the same direction. The protrusion 2523 protrudes from the side of the support rod 2521 toward the unlocking structure 26, so that the unlocking structure 26 can push the protrusion 2523 to move, thereby pushing the support rod 2521 and the locking protrusion 2522 to move.

[0182] Through the above technical solution, a protrusion 2523 is provided on the support rod 2521 so that the unlocking structure 26 can push up to drive the support rod 2521 and the locking protrusion 2522 to move, which is convenient for operation; the locking protrusion 2522 and the protrusion 2523 are located on the same side of the connection between the support rod 2521 and the guide rail 21, which can facilitate the layout and assembly.

[0183] In some embodiments, the middle part of the support rod 2521 can be rotatably connected to the guide rail 21, and the locking protrusion 2522 and the protrusion 2523 can be respectively disposed at opposite ends of the support rod 2521. Correspondingly, an annular platform can be provided on the locking block 251, and a first locking groove 2512 and a second locking groove 2513 can be provided on the inner wall of the annular platform. The locking protrusion 2522 extends into the annular platform so as to be placed into the first locking groove 2512 or the second locking groove 2513 to lock the locking block 251.

[0184] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The protrusion 2523 is located at the other end of the support rod 2521, and the locking protrusion 2522 is located in the middle area of ​​the support rod 2521.

[0185] The protrusion 2523 located at the other end of the support rod 2521 means that the protrusion 2523 is located on the support rod 2521 at the end away from the connection between the support rod 2521 and the guide rail 21.

[0186] The middle area refers to the area on the support rod 2521 excluding the two ends.

[0187] The above technical solution facilitates the setting of the position of the protrusion 2523, and the torque required to push the protrusion 2523 is small, so that the unlocking structure 26 can push the protrusion 2523, and it is also convenient to set the position of the unlocking structure 26.

[0188] In some embodiments, the locking protrusion 2522 may be provided at the other end of the support rod 2521, and the protrusion 2523 may be provided in the middle region of the support rod 2521, so that when the protrusion 2523 is pushed, the locking protrusion 2522 has a larger displacement.

[0189] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The protrusion 2523 has a guide slope 25231 on the side facing the other end of the support rod 2521.

[0190] The guide slope 25231 refers to the slope that is set on one side of the protrusion 2523 and is inclined in the direction of the length of the support rod 2521.

[0191] With the above technical solution, a guide slope 25231 is provided on the protrusion 2523. During the movement of the support 23 along the guide rail 21, it is convenient for the unlocking structure 26 to move away from the protrusion 2523 so that the support rod 2521 can rebound, or move to the protrusion 2523 to press the protrusion 2523 to unlock.

[0192] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 11 The locking structure 25 includes a support plate 253, a locking block 251 and a locking assembly 252, all of which are mounted on the support plate 253. The support plate 253 is mounted on the guide rail 21.

[0193] Support plate 253 refers to a plate used for installation and support. Support plate 253 can be made of materials such as steel and aluminum alloy. It can also be made of materials such as plastic and ceramic.

[0194] Both the locking block 251 and the locking assembly 252 are mounted on the support plate 253 so that the support plate 253 can support the locking block 251 and the locking assembly 252, thereby making the locking structure 25 a whole for easy assembly.

[0195] By using the above technical solution, a support plate 253 is set to support the locking block 251 and the locking assembly 252, which can realize the separate assembly of the locking structure 25 and then the whole assembly is installed on the guide rail 21, which facilitates assembly.

[0196] In some embodiments, the locking block 251 and the locking assembly 252 can be directly mounted on the guide rail 21.

[0197] In some embodiments, please refer to Figures 1 to 4 The sliding door hinge mechanism 20 also includes a first stop structure 214, which is installed at one end of the guide rail 21 to limit the support 23 from moving to the position at one end of the guide rail 21.

[0198] The first stop structure 214 refers to a structure used to limit the movement position of the starting end 2101 of the guide rail 21 from the support 23. The first stop structure 214 can be a structural component in the shape of a plate, block, column, etc.

[0199] The first stop structure 214 is installed at one end of the guide rail 21, which means that the first stop structure 214 is fixed to one end of the guide rail 21 by welding, fastener connection or other means.

[0200] One end of the guide rail 21 is the starting end 2101 of the guide rail 21.

[0201] The first stop structure 214 is used to limit the position of the support 23 to one end of the guide rail 21. This means that when the support 23 moves along the guide rail 21 towards the starting end 2101, it contacts the first stop structure 214 to prevent the support 23 from moving further, thus limiting the position of the support 23 towards the starting end 2101.

[0202] The above technical solution allows the first stop structure 214 to limit the position of one end of the support 23 moving towards the guide rail 21.

[0203] In some embodiments, the first stop structure 214 is provided with a first buffer pad 2141 to buffer the impact of the support 23. The first buffer pad 2141 can be made of elastic structures such as rubber pads and silicone pads.

[0204] In some embodiments, when the sliding door hinge mechanism 20 includes a locking structure 25 and a first stop structure 214, the first stop structure 214 can cooperate with the locking structure 25 to limit the position of the support 23 moving toward the starting end 2101, and the first stop structure 214 can also protect the locking structure 25 to reduce the risk of the locking structure 25 being damaged by the impact of the support 23 moving.

[0205] In some embodiments, the sliding door hinge mechanism 20 further includes a second stop structure 215, which is mounted on the other end of the guide rail 21 to limit the support 23 from moving to the position of the other end of the guide rail 21.

[0206] The second stop structure 215 refers to a structure used to limit the movement of the end 2102 of the guide rail 21 from the support 23. The second stop structure 215 can be a structural component in the shape of a plate, block, column, etc.

[0207] The second stop structure 215 is installed at one end of the guide rail 21, which means that the second stop structure 215 is fixed to the other end of the guide rail 21 by welding, fastener connection or other means.

[0208] The other end of guide rail 21 is the end 2102 of guide rail 21.

[0209] The second stop structure 215 is used to limit the support 23 from moving to the other end of the guide rail 21. This means that when the support 23 moves along the guide rail 21 towards the end 2102, it contacts the second stop structure 215, thereby preventing the support 23 from moving further and limiting the position of the support 23 towards the end 2102.

[0210] The above technical solution allows the first stop structure 214 to limit the movement of one end of the support 23 to the guide rail 21. The second stop structure 215 can be used to limit the movement of the other end of the support 23 to the guide rail 21.

[0211] In some embodiments, the second stop structure 215 is provided with a second buffer pad to buffer the impact of the support 23. The second buffer pad can be made of elastic materials such as rubber pads or silicone pads.

[0212] In some embodiments, please refer to Figures 3 to 5 The guide rail 21 is provided with a slide groove 210 extending along the first direction. The two side walls of the slide groove 210 are an upper side wall 211 and a lower side wall 212, respectively. A guide portion 213 is provided on the upper side wall 211. A bearing wheel 231 is installed on the support 23. The bearing wheel 231 is placed in the slide groove 210 and supported on the lower side wall 212. A guide structure 232 is installed on the support 23. The guide structure 232 is slidably installed on the guide portion 213.

[0213] The slide groove 210 is a groove structure provided on the guide rail 21. The slide groove 210 extending along the first direction means that the direction in which the length of the slide groove 210 is located is parallel to the first direction.

[0214] The depth direction of the groove 210 refers to the direction from the groove opening to the bottom of the groove 210. The depth direction of the groove 210 is perpendicular to the first direction. The width direction of the groove 210 refers to the direction from one sidewall of the groove 210 to the other sidewall.

[0215] The height direction Z refers to the height direction of the sliding door hinge mechanism 20 in application. For example, if the sliding door hinge mechanism 20 is applied to vehicle 100, the height direction is the height direction Z of vehicle 100. In application, the width of the sliding door hinge mechanism 20 is parallel to the height direction Z.

[0216] The upper sidewall 211 and the lower sidewall 212 refer to the opposite sidewalls of the groove 210. In the application, the upper sidewall 211 is located above the lower sidewall 212.

[0217] The guide part 213 refers to the structural part provided on the upper side wall 211 that can play a guiding or directing role.

[0218] The support roller 231 refers to the roller used to support the support 23. The support roller 231 is placed in the slide groove 210 so that the support roller 231 is positioned and guided to move by the slide groove 210.

[0219] The bearing wheel 231 is supported on the lower side wall 212, which means that the bearing wheel 231 is placed in the groove 210. In application, the lower side wall 212 is located below the upper side wall 211 in the height direction Z. In this way, the bearing wheel 231 can be supported on the lower side wall 212, and the lower side wall 212 supports the bearing wheel 231, thereby supporting the support 23 and the connecting rod 22.

[0220] The guide structure 232 refers to the structure that guides the movement of the bearing wheel 231. The guide structure 232 installed on the support 23 means that the guide structure 232 is supported on the support 23 so as to guide the movement of the support 23.

[0221] The guide structure 232 is slidably mounted on the guide portion 213 to guide the movement of the structure 232 via the guide portion 213. As an example, the guide portion 213 can be a baffle 2131 provided on the upper sidewall 211. The guide structure 232 includes a guide wheel 2321 mounted on the support 23, which abuts against the baffle 2131, thereby guiding the guide wheel 2321 to move the bearing wheel 231. This also effectively reduces the risk of the bearing wheel 231 detaching from the slide groove 210. As an example, the guide portion 213 can be a slide rail, and the guide structure 232 can use a slider. The slider is mounted on the slide rail to guide its movement, thereby guiding the support 23 to move. The cooperation between the slider and the slide rail further reduces the risk of the bearing wheel 231 detaching from the slide groove 210.

The unlocking structure 26 includes a pressure plate 262 and a top block 261. The top block 261 is disposed on the pressure plate 262, and the pressure plate 262 is connected to the connecting rod 22.

[0224] By hinged link 22 to support 23 and slidably mounted support 23 on guide rail 21, link 22 can be folded and unfolded. In use, link 22 can be locked in the unfolded state as support 23 moves along guide rail 21. In the folded state, the position of support 23 can be locked. By switching the state of link 22, the distance between sliding door 111 and vehicle body 110 can be adjusted, so that guide rail 21 can be used in a straight line without bending the end of guide rail 21, thereby reducing the space occupied in the width direction of vehicle 100.

[0225] According to some embodiments of this application, this application also provides a vehicle 100, including a sliding door hinge mechanism 20 as described above.
