Description

Technical Field

[0001] This application relates to the field of folding mechanism design technology, specifically to a folding mechanism, a vehicle roof, and a vehicle. Background Technology

[0002] Existing folding mechanisms typically employ a motor-driven slider to move, which in turn moves a foldable substrate (which can be any foldable structure such as tarpaulin, leather, paper, or plastic sheet). The foldable substrate unfolds or folds during the movement, and the existing slider remains in a movable state. When the foldable substrate stops at a midway point, the movable slider may slip due to external influences, making it impossible for the substrate to be fixed at the midway point.

[0003] There is currently no effective solution to the aforementioned technical problems. Utility Model Content

[0004] This application provides a folding mechanism, a vehicle roof, and a vehicle, aiming to improve the problem in the prior art that foldable substrates cannot stop in the middle position during use.

[0005] According to one aspect of the embodiments of this application, a folding mechanism is provided, comprising: a sliding guide rail, on which a plurality of locking spaces are provided, the plurality of locking spaces being spaced apart along the length direction of the sliding guide rail; and a locking assembly, comprising a plurality of locking assemblies, each locking assembly corresponding to a plurality of locking spaces, the locking assembly including a locking slider and a locking member, at least a portion of the locking member being disposed within the locking space, the locking member being movably disposed along the depth direction of the locking space, so that the locking member has an avoidance position and a locking position, when the locking member is in the locking position, the locking member locks the locking slider in the current position, and when the locking member is in the avoidance position, the locking slider is slidable along the sliding guide rail; wherein, the plurality of locking sliders are all used to connect to a foldable substrate, and the sliding of the locking sliders along the sliding guide rail can drive the foldable substrate to perform folding and unfolding movements.

[0006] The embodiments of this application achieve the following technical effects: the one-to-one correspondence between the locking space and the locking components enables individual locking of multiple positions of the foldable substrate. When the locking component locks the locking slider, the movement of the locking slider is restricted, thereby fixing the position of the foldable substrate. When the locking slider is unlocked, the locking slider can drive the foldable substrate to move along the sliding guide rail, realizing the folding or unfolding of the foldable substrate. Since there are multiple locking components, the state of each locking component can be adjusted as needed to lock and release the locking components at different positions on the sliding guide rail, thereby realizing the partial folding of the foldable substrate. This allows the foldable substrate to have a partially open state between fully open and fully closed. Furthermore, the size of the opening in the partially open state can be adjusted according to actual needs, achieving the purpose of adjusting the degree of opening of the foldable substrate according to user needs and fixing the foldable substrate in the current state, solving the problem in the prior art that the foldable substrate cannot stop in the middle position during use.

[0007] Furthermore, the folding mechanism also includes a drive slider, which is slidably disposed along the sliding guide rail. During the sliding process of the drive slider, the drive slider can drive the locking member to move from the locking position to the avoidance position, thereby unlocking the locking slider.

[0008] The above-mentioned optional embodiments of this application achieve the following technical effects: the setting of the driving slider allows the locking and unlocking of the locking component to be switched by simply operating the driving slider, making the state switching of the locking component more convenient.

[0009] Furthermore, along the length of the sliding guide rail, adjacent locking sliders and driving sliders are connected by a linkage assembly. The locking slider and driving slider slide along the sliding guide rail, which can drive the linkage assembly to fold and unfold. At least one of the linkage assembly, locking slider, and driving slider is connected to the foldable substrate.

[0010] The above-mentioned optional embodiments of this application achieve the following technical effects: The linkage assembly can connect multiple locking sliders into a linkage mechanism, that is, two adjacent locking sliders can be linked when they are in the unlocked state, avoiding the need to drive each locking slider individually when they are in an isolated state, making the control of the foldable substrate more convenient and faster. At the same time, the locking slider adjacent to the driving slider is also connected to the driving slider through the linkage assembly, so that the movement of the driving slider can be transmitted to the other locking sliders through the adjacent locking sliders, thereby achieving the technical effect that the movement of one driving slider drives multiple locking sliders to follow the movement, reducing the operating cost of each locking component.

[0011] Furthermore, the sliding guide rail has an unfolding end and a folding end that are arranged opposite to each other along the length direction of the sliding guide rail. The driving slider has an initial position. When the driving slider is in the initial position, the driving slider is on the side of the locking component near the unfolding end that is away from the other locking components. During the process of the driving slider moving from the unfolding end to the folding end, the driving slider drives the locking component to switch to the avoidance position and drives the locking slider to move towards the folding end so that the foldable substrate can fold. During the process of the driving slider moving from the folding end to the unfolding end, the locking slider moves synchronously so that the foldable substrate can unfold.

[0012] The above-mentioned optional embodiments of this application achieve the following technical effects: When the drive slider is in the initial position, that is, at the unfolded end of the sliding guide rail, the foldable substrate is in a completely closed state. When the drive slider moves from the unfolded end to the folded end, the drive slider will unlock each locking slider in sequence and drive each locking slider to move synchronously towards the folded end, thereby realizing the folding of the foldable substrate. During this movement, the drive slider can stop at any position as needed. At this time, the locking slider that has not yet been unlocked is still locked so that the corresponding part of the foldable substrate unfolds. The unlocked locking slider follows the movement of the drive slider and stops at the current position. The corresponding other part of the foldable substrate folds, realizing the partial open state of the foldable substrate. When the drive slider unlocks and drives all the locking sliders to move to the folded end, the foldable substrate is in a completely open state. When the foldable substrate needs to switch from a completely open state to a completely closed state, the drive slider moves in the opposite direction. When the drive slider moves, due to the setting of the linkage assembly, each locking slider moves along with it, and each locking slider is locked by the locking member when it moves to the corresponding locking member. When the drive slider returns to the unfolded end, the foldable substrate switches to a completely closed state. In this embodiment, the foldable substrate can be folded and unfolded simply by operating the drive slider to move along the length of the sliding guide and stop at a designated position. Furthermore, during the movement, each locking slider moves sequentially according to its positional order with the drive slider, making the overall movement process orderly and less prone to interference between them.

[0013] Furthermore, in each locking assembly, a first mating part is provided on the locking slider, and a second mating part is provided on the locking member. One of the first mating part and the second mating part is a mating groove, and the other of the first mating part and the second mating part is a mating protrusion. When the locking member is in the locking position, the mating protrusion extends into the mating groove. When the locking member is in the clearance position, the mating protrusion separates from the mating groove.

[0014] The above-mentioned optional embodiments of this application achieve the following technical effects: the locking member and the sliding guide rail are connected in a relatively fixed manner. When the locking member is in the locked position, the mating groove and the mating protrusion correspond, so that the mating protrusion is inserted into the mating groove, thereby fixing the locking member and the locking slider relatively, thus fixing the locking slider in the current position. When the locking member is in the avoidance position, the mating groove and the mating protrusion are misaligned, and the mating protrusion cannot be inserted into the mating groove. At this time, the locking member cannot be fixedly connected with the locking slider, and the locking slider still maintains a free sliding state. The mating setting of the mating groove and the mating protrusion can provide a large biting force, so that the connection between the locking member and the locking slider is stable.

[0015] Furthermore, each of the first mating parts is offset in the width direction of the sliding guide rail.

[0016] The above-mentioned optional embodiments of this application achieve the following technical effects: by setting misaligned first mating parts on different locking components, each locking slider can only be locked by its corresponding locking member, and cannot be locked by the locking members of other locking components. When each locking slider moves along the sliding guide rail, it can be fixed at a designated position on the sliding guide rail, ensuring that the foldable substrate can achieve smooth opening and closing actions.

[0017] Furthermore, a locking base is provided within the locking space, and the locking component includes a locking pin with a second mating part. The locking pin can move along the depth direction of the locking space to switch the locking component between a clearance position and a locking position. The locking pin is connected to the locking base through an elastic element. When the locking pin is in the clearance position, the elastic element is in a compressed state, and when the locking pin is in the locking position, the elastic element is in a free state.

[0018] The above-mentioned optional embodiments of this application achieve the following technical effects: the elastic element in its natural state can ensure that the locking pin is in the locking position to lock the locking slider. When the driving slider presses the locking pin down to the avoidance position, the elastic element is compressed. Due to the automatic return function of the elastic element, after the driving slider leaves, the elastic element will automatically return the locking pin to the locking position, ensuring that each locking slider is in the state of being locked by the locking pin when there is no movement intervention of the driving slider, avoiding the problems of tarpaulin shaking and abnormal noise of parts caused by the locking slider being in a free movement state.

[0019] Furthermore, the locking pin has a connecting space. When the locking pin is in the locked position, at least part of the locking slider extends into the connecting space, and a second mating part is provided on the side wall of the connecting space.

[0020] The above-mentioned optional embodiments of this application achieve the following technical effects: the connecting space can be used to accommodate at least part of the locking slider, further realizing the limiting of the locking slider and improving the locking stability of the locking slider.

[0021] Furthermore, the locking slider includes a slider body, the slider body has an avoidance channel, the avoidance channel has an avoidance opening on the side facing the bottom of the sliding guide rail, and the side wall of the avoidance channel away from the avoidance opening has a first mating part, wherein the first mating part is a mating groove and the second mating part is a mating protrusion. When the locking pin is in the locking position, the mating protrusion extends into the mating groove.

[0022] The above-mentioned optional embodiments of this application achieve the following technical effects: by providing an avoidance opening at the bottom of the avoidance channel of the slider body, the locking pin moves upward along the depth direction of the sliding guide rail, so that the mating protrusion provided on the locking pin extends into the mating groove of the slider body. When the locking pin moves downward along the depth direction of the sliding guide rail, the mating protrusion provided on the locking pin disengages from the mating groove of the slider body, thereby realizing the rapid locking and releasing of the slider and the locking pin.

[0023] Furthermore, the locking pin is provided with a guide slope, and the height distance between the guide slope and the sliding guide rail gradually decreases along the direction away from the locking slider.

[0024] The above-mentioned optional embodiments of this application achieve the following technical effects: the setting of the guide slope facilitates the gradual pressing of the locking pin during the movement of the driving slider toward the locking slider, thereby unlocking the locking slider.

[0025] Furthermore, the linkage assembly includes a first link, a second link, and a third link, wherein the first end of the third link, the first end of the first link, and the first end of the second link are all rotatably connected to the same pivot, the second end of the first link and the second end of the second link are all rotatably connected to one of two adjacent locking sliders, and the second end of the third link is rotatably connected to the other of the two adjacent locking sliders; and / or, the second end of the third link is connected to a drive slider, and the locking slider adjacent to the drive slider is rotatably connected to the second end of the first link and the second end of the second link.

[0026] The above-mentioned optional embodiments of this application achieve the following technical effects: the arrangement of the first link, the second link, and the third link can form a triangular pyramid structure between two adjacent locking sliders or between the driving slider and the locking slider, so that the movement of the locking slider and the driving slider can be more stable.

[0027] Furthermore, there are two sliding guide rails, which are set at a distance along the width direction of the sliding guide rails. Each sliding guide rail is provided with multiple locking spaces, multiple locking components and driving sliders. The locking components and driving sliders located on the two sliding guide rails are correspondingly arranged along the width direction of the sliding guide rails. The two corresponding locking sliders are connected by a first crossbar, and / or the two corresponding connecting rod components are connected by a second crossbar, and / or the two corresponding driving sliders are connected by a third crossbar.

[0028] The above-mentioned optional embodiments of this application achieve the following technical effects: the arrangement of the first crossbar, the second crossbar, and the third crossbar can ensure that the corresponding two components move synchronously, thereby making the movement process on the two sliding guide rails consistent, and ensuring that the folding and unfolding processes on both sides of the foldable substrate are consistent.

[0029] Furthermore, the folding mechanism also includes a drive assembly, which includes: a flexible shaft, at least a portion of which passes through the sliding guide rail and is connected to the drive slider; a transmission gear, which is in contact with the flexible shaft and whose rotation can drive the flexible shaft to move along its axial direction, thereby driving the drive slider to move along the length direction of the sliding guide rail; and a drive member, the output end of which is connected to the transmission gear and can drive the transmission gear to rotate.

[0030] The above-mentioned optional embodiments of this application achieve the following technical effects: the driving component drives the transmission gear to rotate, thereby driving the flexible shaft to move axially, thereby driving the driving slider to move along the length direction of the sliding guide rail. By adjusting the rotation speed of the transmission gear, the movement speed of the driving slider can be changed. By adjusting the rotation angle and direction of the transmission gear, the movement stroke and movement direction of the driving slider can be changed, making the movement control of the driving slider more convenient.

[0031] Furthermore, there are two flexible shafts, each corresponding to one of the two drive sliders. Both flexible shafts are in contact with the transmission gears, and the rotation of the transmission gears can drive the two flexible shafts to move synchronously.

[0032] The above-mentioned optional embodiments of this application achieve the following technical effects: by using a transmission gear to drive two flexible shafts to move synchronously, the driving cost of the two driving sliders can be reduced and the folding mechanism of the vehicle soft top can be simplified.

[0033] According to another aspect of the embodiments of this application, a vehicle roof is provided, the vehicle roof including a folding mechanism, the folding mechanism being the folding mechanism described above.

[0034] The embodiments of this application achieve the following technical effects: When the folding mechanism in the above embodiments is applied to the vehicle roof, the tarpaulin of the vehicle roof is connected to the folding mechanism as a foldable substrate. The tarpaulin can stop at any intermediate position during the folding and unfolding movements, thereby obtaining a variety of tarpaulin shapes. For example, the tarpaulin can be fully unfolded, fully folded, or partially folded, so that the tarpaulin shape better meets the user's needs and improves the user's experience.

[0035] According to another aspect of the embodiments of this application, a vehicle is provided, the vehicle including at least one of a folding mechanism and a vehicle roof, wherein the folding mechanism is the folding mechanism described above, and the vehicle roof is the vehicle roof described above.

[0036] The embodiments of this application achieve the following technical effects: By applying the folding mechanism in the above embodiments to vehicles, the foldable substrate on the vehicle can remain in the middle position during the movement of the folding mechanism, thereby obtaining a folding form that better meets the user's needs. The foldable substrate on the vehicle can be the tarpaulin of the roof, the curtains of the windows, etc. By applying the vehicle roof in the above embodiments to vehicles, the vehicle roof can be made more intelligent and stable. The vehicle roof can have a partially open state in addition to being fully open and fully closed, and it has good stability in each state, reducing abnormal noise caused by shaking of the mechanism and improving the user experience.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0060] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0061] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0062] In existing folding soft tops, motors are typically used to drive the folding and opening functions. When closing, the motor relies on its self-locking force. After repeated use, wear and tear on the motor and its components can lead to the soft top not closing properly. Furthermore, because the slider that drives the soft top is not locked, the soft top can only stay in the fully open or fully closed position. When it stops in the middle, the unrestrained slider will collide and produce abnormal noise.

[0063] Combination Figures 1 to 9 As shown, a folding mechanism is provided according to a specific embodiment of this application.

[0064] Specifically, the folding mechanism includes a sliding guide rail 4 and a locking assembly. The sliding guide rail 4 has multiple locking spaces 400, spaced apart along its length. Multiple locking assemblies are provided, each corresponding to one of the locking spaces 400. Each locking assembly includes a locking slider 2 and a locking member 6. At least a portion of the locking member 6 is located within the locking space 400. The locking member 6 is movable along the depth of the locking space 400, allowing it to have both a clearance position and a locking position. When the locking member 6 is in the locking position, it locks the locking slider 2 in that position. When the locking member 6 is in the clearance position, the locking slider 2 can slide along the sliding guide rail 4. All locking sliders 2 are used to connect to the foldable substrate. The sliding of the locking slider 2 along the sliding guide rail 4 drives the foldable substrate to perform folding and unfolding movements.

[0065] The embodiments of this application achieve the following technical effects: the locking space 400 and the locking components are set in a one-to-one correspondence, which can realize the individual locking of multiple positions of the foldable substrate. When the locking component 6 locks the locking slider 2, the locking slider 2 is restricted from moving, thereby fixing the position of the foldable substrate. When the locking slider 2 is unlocked, the locking slider 2 can drive the foldable substrate to move along the sliding guide rail 4, realizing the folding or unfolding of the foldable substrate. Since there are multiple locking components, the state of each locking component can be adjusted as needed to realize the locking and releasing of the locking component 6 at different positions on the sliding guide rail 4, thereby realizing the partial folding of the foldable substrate. This allows the foldable substrate to have a partially open state between fully open and fully closed. Furthermore, the size of the opening in the partially open state can be adjusted according to actual needs, so as to achieve the purpose of adjusting the degree of opening of the foldable substrate according to user needs and fixing the foldable substrate in the current state, thus solving the problem in the prior art that the foldable substrate cannot stop in the middle position during use.

[0066] The foldable substrate can be any foldable structure such as soft tarpaulin, leather, paper, or plastic sheet.

[0067] In this embodiment, the locking slider 2 can be driven individually, that is, each locking slider 2 corresponds to a driving mechanism. When the locking slider 2 is locked by the locking member 6, the driving mechanism can stop driving.

[0068] Furthermore, the folding mechanism also includes a drive slider 201, which is slidably disposed along the sliding guide rail 4. During the sliding process, the drive slider 201 can drive the locking member 6 to move from the locked position to the avoidance position, thereby unlocking the locking slider 2.

[0069] The above optional embodiments of this application achieve the following technical effects: the setting of the drive slider 201 allows the locking and unlocking switching of the locking component to be realized by simply operating the drive slider 201, making the state switching of the locking component more convenient.

[0070] It should be noted that in some embodiments, multiple drive sliders 201 can be set, and multiple drive sliders 201 are set one-to-one with multiple locking elements 6. By operating the drive slider 201 at a specified position to move, the locking slider 2 at the specified position can be unlocked.

[0071] Furthermore, along the length of the sliding guide rail 4, adjacent locking sliders 2 and driving slider 201 are connected by a connecting rod assembly 5. The locking slider 2 and driving slider 201 slide along the sliding guide rail 4, which can drive the connecting rod assembly 5 to fold and unfold. At least one of the connecting rod assembly 5, locking slider 2, and driving slider 201 is connected to the foldable substrate.

[0072] The above-mentioned optional embodiments of this application achieve the following technical effects: The linkage assembly 5 can connect multiple locking sliders 2 into a linkage mechanism, that is, two adjacent locking sliders 2 can be linked when they are in the unlocked state, avoiding the need to drive each locking slider 2 individually when they are in an isolated state, making the control of the foldable substrate more convenient and faster. At the same time, the locking slider 2 adjacent to the driving slider 201 is also connected to the driving slider 201 through the linkage assembly 5, so that the movement of the driving slider 201 can be transmitted to the other locking sliders 2 through its adjacent locking sliders 2, thereby achieving the technical effect that the movement of one driving slider 201 drives multiple locking sliders 2 to follow the movement, reducing the operating cost of each locking component.

[0073] Furthermore, the sliding guide rail 4 has an unfolding end and a folding end that are arranged opposite to each other along the length direction of the sliding guide rail 4. The driving slider 201 has an initial position. When the driving slider 201 is in the initial position, the driving slider 201 is on the side of the locking component near the unfolding end that is away from the other locking components. During the process of the driving slider 201 moving from the unfolding end to the folding end, the driving slider 201 drives the locking component 6 to switch to the avoidance position and drives the locking slider 2 to move towards the folding end so that the foldable substrate can fold. During the process of the driving slider 201 moving from the folding end to the unfolding end, the locking slider 2 moves synchronously so that the foldable substrate can unfold.

[0074] The above-mentioned optional embodiments of this application achieve the following technical effects: When the driving slider 201 is in the initial position, that is, at the unfolded end of the sliding guide rail 4, the foldable substrate is in a completely closed state. When the driving slider 201 moves from the unfolded end to the folded end, the driving slider 201 will unlock each locking slider 2 in sequence and drive each locking slider 2 to move synchronously towards the folded end, thereby realizing the folding of the foldable substrate. During this movement, the driving slider 201 can stay at any position as needed. At this time, the locking slider 2 that has not yet been unlocked is still locked, so that the corresponding part of the foldable substrate unfolds. The unlocked locking slider 2 follows the driving slider 201. 1. The foldable substrate moves and stops at its current position, while the corresponding other part of the foldable substrate folds, achieving a partially open state. When the drive slider 201 unlocks and drives all the locking sliders 2 to move to the folding end, the foldable substrate is in a fully open state. When the foldable substrate needs to switch from a fully open state to a fully closed state, the drive slider 201 moves in the opposite direction. Due to the linkage assembly 5, each locking slider 2 moves along with the drive slider 201, and each locking slider 2 is locked by the corresponding locking member 6 when it moves to the corresponding locking member 6. When the drive slider 201 returns to the unfolded end, the foldable substrate switches to a fully closed state. In this embodiment, only the drive slider 201 needs to be operated to move along the length direction of the sliding guide rail 4 and stop at a designated position to achieve the folding and unfolding of the foldable substrate. Furthermore, during the movement, each locking slider 2 moves sequentially according to its positional order with the drive slider 201, making the overall movement process orderly and less prone to interference between them.

[0075] Furthermore, in each locking assembly, the locking slider 2 is provided with a first mating part 21, and the locking member 6 is provided with a second mating part 61. One of the first mating part 21 and the second mating part 61 is a mating groove, and the other of the first mating part 21 and the second mating part 61 is a mating protrusion. When the locking member 6 is in the locking position, the mating protrusion extends into the mating groove. When the locking member 6 is in the clearance position, the mating protrusion separates from the mating groove.

[0076] The above-mentioned optional embodiments of this application achieve the following technical effects: the locking member 6 and the sliding guide rail 4 are connected in a relatively fixed manner. When the locking member 6 is in the locked position, the mating groove and the mating protrusion correspond, so that the mating protrusion is inserted into the mating groove, and the locking member 6 and the locking slider 2 are relatively fixed, thereby fixing the locking slider 2 in the current position. When the locking member 6 is in the avoidance position, the mating groove and the mating protrusion are misaligned, and the mating protrusion cannot be inserted into the mating groove. At this time, the locking member 6 cannot be fixedly connected with the locking slider 2, and the locking slider 2 still maintains a free sliding state. The mating setting of the mating groove and the mating protrusion can provide a large biting force, so that the connection between the locking member 6 and the locking slider 2 is stable.

[0077] Furthermore, each of the first mating parts 21 is offset in the width direction of the sliding guide rail.

[0078] The above-mentioned optional embodiments of this application achieve the following technical effects: by setting misaligned first mating parts 21 on different locking components, each locking slider 2 can only be locked by the corresponding locking member 6, and cannot be locked by the locking members 6 of other locking components. When each locking slider 2 moves along the sliding guide rail 4, it can be fixed at a designated position on the sliding guide rail 4, ensuring that the foldable substrate can achieve smooth opening and closing actions.

[0079] Furthermore, a locking base 801 is provided within the locking space 400, and the locking member 6 includes a locking pin 601. A second mating part 61 is provided on the locking pin 601. The locking pin 601 can move along the depth direction of the locking space 400 so that the locking member 6 can switch between a clearance position and a locking position. The locking pin 601 is connected to the locking base 801 through an elastic member 7. When the locking pin 601 is in the clearance position, the elastic member 7 is in a compressed state. When the locking pin 601 is in the locking position, the elastic member 7 is in a free state.

[0080] The above-mentioned optional embodiments of this application achieve the following technical effects: the elastic element 7 in its natural state can ensure that the locking pin 601 is in the locking position to lock the locking slider 2. When the driving slider 201 presses the locking pin 601 down to the avoidance position, the elastic element 7 is compressed. Due to the automatic return function of the elastic element 7, after the driving slider 201 leaves, the elastic element 7 will automatically return the locking pin 601 to the locking position, ensuring that each locking slider 2 is in the state of being locked by the locking pin 601 when there is no movement intervention of the driving slider 201, avoiding the problem of tarpaulin shaking and abnormal noise of parts caused by the locking slider 2 being in a free movement state.

[0081] In one exemplary embodiment of this application, the locking space 400 is a locking hole that extends through the depth direction of the sliding guide rail 4. After the locking pin 601 is pre-connected to the locking base 801, the locking base 801 can be assembled from the bottom upward along the depth direction of the sliding guide rail 4, so that the locking pin 601 is located in the locking hole. The locking base 801 can be connected to the sliding guide rail 4 by fasteners such as bolts.

[0082] Furthermore, the locking pin 601 has a connecting space 6010. When the locking pin 601 is in the locked position, at least part of the locking slider 2 extends into the connecting space 6010. A second mating part 61 is provided on the side wall of the connecting space 6010.

[0083] The above optional embodiments of this application achieve the following technical effects: the connecting space 6010 can be used to accommodate at least part of the locking slider 2, further limiting the locking slider 2 and improving the locking stability of the locking slider 2.

[0084] In one exemplary embodiment of this application, the locking pin 601 includes two locking blocks spaced apart along the length of the sliding guide rail 4, forming a connecting space 6010 between the two locking blocks. When the locking slider 2 is locked, the two locking blocks are located on both sides of the locking slider 2, limiting and fixing the locking slider 2. The locking space 400 has two openings on the surface of the sliding guide rail 4, each opening corresponding to a locking block, so that the locking block can move up and down in the depth direction of the sliding guide rail 4.

[0085] Furthermore, the locking slider 2 includes a slider body, the slider body has an avoidance channel, the avoidance channel has an avoidance opening on the side facing the bottom of the sliding guide rail 4, and the side wall of the avoidance channel away from the avoidance opening has a first mating part 21, wherein the first mating part 21 is a mating groove and the second mating part 61 is a mating protrusion. When the locking pin 601 is in the locking position, the mating protrusion extends into the mating groove.

[0086] The above-mentioned optional embodiments of this application achieve the following technical effects: by providing an avoidance opening at the bottom of the avoidance channel of the slider body, the locking pin 601 moves upward along the depth direction of the sliding guide rail 4, so that the mating protrusion provided on the locking pin 601 extends into the mating groove of the slider body. When the locking pin 601 moves downward along the depth direction of the sliding guide rail 4, the mating protrusion provided on the locking pin 601 disengages from the mating groove of the slider body, thereby realizing the rapid locking and releasing of the slider 2 and the locking pin 601.

[0087] like Figure 8 and Figure 9 As shown, the locking slider 2 along Figure 8 The movement process shown is the process of moving from the folded end to the unfolded end. The locking slider 2 first contacts the left side of the locking pin 601, pressing the pin 601 down. When the locking slider 2 moves to the connecting space 6010, the locking pin 601 springs upward under the action of elastic force. The engaging protrusion of the locking pin 601 extends into the engaging groove of the locking slider 2 to lock the slider 2 in its current position. The engaged locking slider 2 and locking pin 601 are as follows... Figure 9 As shown.

[0088] Furthermore, the locking pin 601 is provided with a guide slope 6011, and the height distance between the guide slope 6011 and the sliding guide rail 4 gradually decreases along the direction away from the locking slider 2.

[0089] The above-mentioned optional embodiments of this application achieve the following technical effects: the setting of the guide slope 6011 facilitates the gradual pressing of the locking pin 601 during the movement of the driving slider 201 toward the locking slider 2, thereby unlocking the locking slider 2.

[0090] Further, the linkage assembly 5 includes a first linkage 501, a second linkage 502, and a third linkage 503, wherein the first end of the third linkage 503, the first end of the first linkage 501, and the first end of the second linkage 502 are all rotatably connected to the same rotating shaft, the second end of the first linkage 501 and the second end of the second linkage 502 are rotatably connected to one of two adjacent locking sliders 2, and the second end of the third linkage 503 is rotatably connected to the other of the two adjacent locking sliders 2; and / or, the second end of the third linkage 503 is connected to the driving slider 201, and the locking slider 2 adjacent to the driving slider 201 is rotatably connected to the second end of the first linkage 501 and the second end of the second linkage 502.

[0091] The above-mentioned optional embodiments of this application achieve the following technical effects: the arrangement of the first link 501, the second link 502, and the third link 503 can form a triangular pyramid structure between two adjacent locking sliders 2 or between the driving slider 201 and the locking slider 2, so that the movement of the locking slider 2 and the driving slider 201 can be more stable.

[0092] Furthermore, there are two sliding guide rails 4, which are arranged at a distance along the width direction of the sliding guide rails 4. Each sliding guide rail 4 is provided with multiple locking spaces 400, multiple locking components and driving sliders 201. The locking components and driving sliders 201 located on the two sliding guide rails 4 are correspondingly arranged along the width direction of the sliding guide rails 4. The two corresponding locking sliders 2 are connected by a first crossbar 301, and / or the two corresponding connecting rod components 5 are connected by a second crossbar 302, and / or the two corresponding driving sliders 201 are connected by a third crossbar 303.

[0093] The above optional embodiments of this application achieve the following technical effects: the arrangement of the first crossbar 301, the second crossbar 302, and the third crossbar 303 can ensure that the corresponding two components move synchronously, thereby making the movement process on the two sliding guide rails 4 consistent, and ensuring that the folding and unfolding processes on both sides of the foldable substrate are consistent.

[0094] Furthermore, the folding mechanism also includes a drive assembly 9, which includes a flexible shaft 91 and a transmission gear 92. At least a portion of the flexible shaft 91 passes through the sliding guide rail 4 and is connected to the drive slider 201. The transmission gear 92 is in contact with the flexible shaft 91, and rotation of the transmission gear 92 can drive the flexible shaft 91 to move along the axial direction of the flexible shaft 91, thereby driving the drive slider 201 to move along the length direction of the sliding guide rail 4. A drive member 93 is also included, with its output end connected to the transmission gear 92, and the drive member 93 can drive the transmission gear 92 to rotate.

[0095] The above-mentioned optional embodiments of this application achieve the following technical effects: the driving component 93 drives the transmission gear 92 to rotate, thereby driving the flexible shaft 91 to move axially, thereby driving the driving slider 201 to move along the length direction of the sliding guide rail 4. By adjusting the rotation speed of the transmission gear 92, the movement speed of the driving slider 201 can be changed. By adjusting the rotation angle and direction of the transmission gear 92, the movement stroke and movement direction of the driving slider 201 can be changed, making the movement control of the driving slider 201 more convenient.

[0096] Furthermore, there are two flexible shafts 91, and the two flexible shafts 91 are arranged in a one-to-one correspondence with the two drive sliders 201. Both flexible shafts 91 are in contact with the transmission gear 92, and the rotation of the transmission gear 92 can drive the two flexible shafts 91 to move synchronously.

[0097] The above-mentioned optional embodiments of this application achieve the following technical effects: by using a transmission gear 92 to drive two flexible shafts 91 to move synchronously, the driving cost of the two side drive sliders 201 can be reduced and the folding mechanism of the vehicle soft top can be simplified.

[0098] In one exemplary embodiment of this application, the driving component 93 is a motor, and the sliding guide rail 4 has a channel for the flexible shaft 91 to pass through. The axial movement of the flexible shaft 91 can drive the driving slider 201 to move. Specifically, the flexible shaft 91 can be an annular structure arranged circumferentially along the soft top frame, and this annular structure passes through the sliding guide rails 4 on both sides. Alternatively, the flexible shaft 91 can also be an arc-shaped structure, with the main body of the arc-shaped structure located in the sliding guide rail 4 where the driving slider 201 is located, and the end of the arc-shaped structure can extend into the sliding guide rail 4 on the other side during movement to hide the end of the arc-shaped structure. The soft top frame includes a crossbar assembly 3, a front crossbeam 101, a rear crossbeam 102, and a motor bracket 94 connected to the crossbeam assembly 1. The motor bracket 94 can be used to fix the driving component 93.

[0099] According to another specific embodiment of this application, a vehicle roof is also provided, the vehicle roof including a folding mechanism, the folding mechanism being the folding mechanism in the above embodiment.

[0100] The embodiments of this application achieve the following technical effects: When the folding mechanism in the above embodiments is applied to the vehicle roof, the tarpaulin of the vehicle roof is connected to the folding mechanism as a foldable substrate. The tarpaulin can stop at any intermediate position during the folding and unfolding movements, thereby obtaining a variety of tarpaulin shapes. For example, the tarpaulin can be fully unfolded, fully folded, or partially folded, so that the tarpaulin shape better meets the user's needs and improves the user's experience.

[0101] This application also provides a preferred embodiment of a folding mechanism for a vehicle soft top.

[0102] Specifically, the folding mechanism includes a crossbeam assembly 1, a locking slider 2, a driving slider 201, a crossbar assembly 3, a sliding guide rail 4, a connecting rod assembly 5, a locking element 6, an elastic element 7, a locking base 801, and a driving assembly 9. There are two sliding guide rails 4, including a first guide rail 401 and a second guide rail 402. The elastic element 7 includes a first spring 701 and a second spring 702. The crossbar assembly 3 includes a first crossbar 301, a second crossbar 302, and a third crossbar 303.

[0103] Among them, such as Figure 1 As shown, the crossbeam assembly 1 includes a front crossbeam 101 and a rear crossbeam 102. Bolt holes are provided in the middle of the front crossbeam 101 and the rear crossbeam 102. Corresponding mounting holes can be provided on the vehicle body to fix the entire folding mechanism to the vehicle body sheet metal. At the same time, the front crossbeam 101 and the rear crossbeam 102 also serve to fix the first guide rail 401 and the second guide rail 402.

[0104] A drive slider 201 and a plurality of locking sliders 2 are provided on the first guide rail 401 and the second guide rail 402. The plurality of locking sliders 2 include a first locking slider 202, a second locking slider 203, a third locking slider 204, and a fourth locking slider 205. The guide rails are provided with grooves that match the locking sliders 2, and the locking sliders 2 can slide on the guide rails.

[0105] A connecting rod assembly 5 is provided between the sliders, such as... Figure 2 As shown, a first connecting rod 501, a second connecting rod 502, and a third connecting rod 503 are provided on the first locking slider 202. The locking slider and the connecting rods are connected by a first crossbar 301. The other end of the third connecting rod 503 is connected to the following connecting rod through the second crossbar 302. When the sliders slide relative to each other, the first crossbar 301 and the second crossbar 302 will rise, and the connecting rods will fold. A soft-top tarpaulin is provided on the crossbar. As the crossbar rises, the tarpaulin folds along with the connecting rods, thus opening the tarpaulin. When the sliders move away from each other, the crossbar lowers, and the connecting rods become more level, thus opening the tarpaulin and closing the roof.

[0106] Specifically, in an exemplary embodiment, taking the linkage assembly between the first locking slider 202 and the driving slider 201 as an example, the first end of the second link 502 is connected to the first locking slider 202, the second end of the second link 502 is connected to the first end of the third link 503, and the second end of the third link 503 is connected to the driving slider 201. The movement of the driving slider 201 causes the third link 503 and the second link 502 to move closer together and forward along the direction of movement of the driving slider 201, folding into a serrated, acute-angled triangle with a small included angle. Multiple linkage assemblies fold closer together into several serrated shapes.

[0107] The folding process of the tarpaulin: The soft-top tarpaulin is fixed to the connecting rod; when the drive slider 201 moves towards the rear crossbeam 102, an angle is formed between the third connecting rod 503 and the second connecting rod 502. As this angle decreases, the soft-top tarpaulin fixed to the third connecting rod 503 and the second connecting rod 502 folds together. Because the soft-top tarpaulin is fixed to the connecting rod, the problem of the tarpaulin shaking in the wind and increasing noise is solved.

[0108] To make the folding of the connecting rod more stable and to make the soft top tarpaulin fold more neatly, a third crossbar 303 is connected between the locking sliders 2 on the left and right sides, a first crossbar 301 is connected between the driving sliders 201 on the left and right sides, and a second crossbar 302 is connected between the hinge point of the third connecting rod 503 and the second connecting rod 502 on the left and right sides.

[0109] To make the movement of the connecting rod more stable, a first connecting rod 501 can be stacked on top of the second connecting rod 502. The first connecting rod 501, the second connecting rod 502 and the third connecting rod 503 on the same side will also form a triangular pyramid shape, which will make the movement on the slide rail more stable.

[0110] When the soft top is fully closed, the positions of the first locking slider 202, the second locking slider 203, the third locking slider 204, and the fourth locking slider 205 are locked by the locking member 6. Figure 3 and Figure 4 As shown, the locking component 6 includes a locking pin 601, a first spring 701, a second spring 702, and a locking base 801. A groove is provided on the guide rail, through which the locking pin passes. A hole is provided at the bottom of the locking pin, allowing a cylinder (i.e., a sliding pin 802) on the locking base 801 to slide within the hole at the bottom of the locking pin. The first spring 701 and the second spring 702 are located at the bottom of the locking pin, passing through the cylinder on the locking base 801. The locking base 801 is fixed to the guide rail by bolts. When no external force is applied, the springs extend, and the locking pin 601 extends from the groove on the guide rail under the spring force. When the locking pin is pressed down by an external force, the springs compress, and the locking pin retracts into the guide rail.

[0111] When the soft top is fully closed, the first locking slider 202, the second locking slider 203, the third locking slider 204, and the fourth locking slider 205 are locked in their respective positions. When the soft top needs to be opened, the drive slider 201 moves along the guide rail from front to back (i.e., from the front crossbeam 101 to the rear crossbeam 102). When it reaches the first locking slider 202, the drive slider 201 continues to move and will compress the locking pin 601. Under pressure, the locking pin 601 retracts into the guide rail, thus unlocking the first locking slider 202. After the first locking slider 202 separates from the locking pin 601, it moves in the direction of opening the soft top under the push of the drive slider 201 until all sliders are unlocked and pushed to the last position, thus fully opening the soft top.

[0112] like Figure 5 As shown, different groove features are provided at different positions of the first locking slider 202, the second locking slider 203, the third locking slider 204, and the fourth locking slider 205, and corresponding protrusion features are provided at the corresponding locking pins. That is, the locking slider 2 can only be matched with the corresponding locking pin 601 to form a locking relationship. The locking slider 2 and the locking pin 601 that do not have a matching relationship will not form a locking relationship.

[0113] When the soft top is fully open and needs to be closed, the drive slider 201 moves from back to front (i.e., from the rear crossbeam 102 to the front crossbeam 101). When the first locking slider 202 passes the first locking pin, the locking pin will retract into the slide rail due to the downward pressure generated by the slider. If the locking slider and the locking pin are not in a corresponding relationship, the locking slider will slide over the locking pin. If the locking slider reaches the matching slider, the locking pin will pop up and lock the slider, ensuring that the soft top is fully closed and locked.

[0114] Specifically, the locking slider 2 slides to the position of the corresponding locking pin 601 and locks, and the stopping of the driving slider 201 is controlled by the braking of the driving component 9.

[0115] Unlocking process: Driven by the flexible shaft 91, the drive slider 201 moves in the direction of the rear crossbeam 102. When the drive slider 201 moves to the guide slope 6011 of the locking pin 601, the locking pin 601 will overcome the spring force and move downward because the drive slider 201 is constrained by the guide rail in the Z direction (i.e., the depth direction of the guide rail). As the drive slider 201 continues to move forward, the locking pin 601 will completely retract into the guide rail, thereby causing the locking slider 2 to disengage from the locking pin 601 and unlocking is achieved. As the drive slider 201 continues to move, it will push the locking slider 2 away from the locked position.

[0116] Locking process: Under the action of the motor (i.e., the aforementioned drive component 93), flexible shaft 91, drive slider 201, and connecting rod assembly 5, the locking slider 2 is driven to move towards the front of the vehicle (i.e., the side where the front crossbeam 101 is located). When the locking slider 2 passes the locking pin 601, under the action of the guide slope 6011, the locking pin 601 will retract into the slide rail under the action of external force. When the locking slider 2 passes the guide slope 6011, the locking pin 601 loses its downward constraint force and pops out under the action of the spring, locking the locking slider 2 in the middle of the locking pin 601. A matching groove is provided between the locking slider 2 and the locking pin 601. The locking pin 601 can only lock the corresponding locking slider 2. Locking sliders 2 without a matching relationship will directly pass over the locking pin 601.

[0117] The locking component solves the problem of the locking slider 2 moving around when the soft top is half open, and the problem of the self-locking of the flexible shaft 91, as well as the problem of large elastic deformation of the flexible shaft 91, spring sheet, and tension band after durability.

[0118] Specifically, the working principle of driver component 9 is as follows:

[0119] The drive motor (i.e., the aforementioned drive component 93) drives two flexible shafts 91 to move. These two flexible shafts 91 respectively drive the left and right drive sliders 201 and locking sliders 2 to move linearly along the guide rail; thus, the connecting rod assembly 5 causes the tarpaulin to fold and expand, realizing the opening and closing of the soft top. One flexible shaft 91 is connected to one drive slider 201, and the other flexible shaft 91 is connected to the other drive slider 201. The two flexible shafts 91 are meshed by a transmission gear 92 and move in opposite directions, thereby causing the drive sliders 201 and locking sliders 2 on both sides to move in the same direction.

[0120] The folding mechanism in this embodiment significantly improves the performance of the folding soft top. During opening and closing, the locking slider 2 ensures the constraint of the soft top in the half-open state, preventing it from swaying due to airflow during driving, thus enhancing the passenger experience. Simultaneously, in the closed state, the locking component 6 provides more holding force to the soft top, preventing accelerated structural aging caused by motor self-locking and resulting in reduced durability. Furthermore, the design of the connecting rod and crossbar makes the folded shape of the soft top more defined and aesthetically pleasing. The crossbar design also provides the soft top with greater resistance to downward pressure when closed, preventing damage from downward pressure.

The foldable substrate on the vehicle can be the tarpaulin of the roof, the curtains of the windows, etc. By applying the vehicle roof in the above embodiments to vehicles, the control of the vehicle roof can be more intelligent and stable. The vehicle roof can have a partially open state in addition to being fully open and fully closed, and it has good stability in each state, reducing abnormal noise caused by shaking of the mechanism and improving the user experience.
