Description

Technical Field

[0001] This application relates to the field of windshield adjustment technology, and in particular to an adjustment structure and windshield device. Background Technology

[0002] Currently, windshield adjusters for ride-on vehicles (such as motorcycles and electric scooters) generally adopt a structure where a single motor drives a single-sided lifting guide rail. Specifically, in traditional solutions, a single drive motor independently controls a rack and pinion mechanism or a four-bar linkage on one side, thereby driving the windshield to adjust its height.

[0003] However, such structures have the following significant drawbacks. When using a rack and pinion mechanism, the up-and-down movement of the rack requires a large space, which restricts the arrangement of other parts inside the vehicle and is also detrimental to the styling design of the front of the vehicle, making it difficult to meet the demands of modern vehicles for a compact layout and aesthetically pleasing design. When using a four-bar linkage, due to its inherent mechanical characteristics, it cannot guarantee that the windshield will be raised and lowered along a straight line. This will cause deviations in the windshield's trajectory during raising and lowering, affecting the accuracy and stability of the adjustment. Utility Model Content

[0004] Therefore, it is necessary to provide an adjustment structure and windshield device to address the problems of traditional regulators requiring a large space and being unable to guarantee the movement trajectory.

[0019] The drive bar is wound around the drive wheel and passes sequentially through the first driven wheel, the second driven wheel, the guide block, the third driven wheel, and the fourth driven wheel until it reaches the drive wheel;

[0020] The direction of movement of the portion of the drive bar located between the first driven wheel and the second driven wheel is consistent with the direction of movement of the portion of the drive bar located between the third driven wheel and the fourth driven wheel.

[0021] In one embodiment, the outer peripheral surface of the drive wheel is provided with a helical groove, and the drive bar is wound around the helical groove;

[0022] And / or, the drive bar includes a rope;

[0024] And / or, the guide block has a guide groove on the side opposite to the drive wheel to accommodate the drive bar and to separate the portion of the drive bar located at the drive wheel.

[0025] In one embodiment, the transmission assembly further includes a drive motor, the output of which is connected to the drive wheel, and the drive motor is configured to drive the drive wheel to rotate forward or in reverse.

[0026] In one embodiment, the mounting base includes a mounting body and a preload assembly, the preload assembly being movably disposed on the mounting body and located at at least one end of each of the guide rails along the second direction, and at least a portion of the driven wheel being mounted on the preload assembly.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing 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, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] As mentioned in the background section, the conventional solution for adjusting the windshield of a riding vehicle usually involves a drive motor independently controlling a rack and pinion mechanism or a four-bar linkage on one side, thereby driving the windshield to rise and fall.

[0052] However, the above structure has the following problems: the rack and pinion mechanism relies on the linear up-and-down movement of the rack, and its stroke direction occupies a large longitudinal space, which restricts the layout of the front parts of the vehicle and negatively affects the freedom of vehicle styling design; the four-bar linkage is prone to nonlinear trajectory deviation during movement, making it difficult to ensure that the windshield rises and falls vertically, and long-term use can easily lead to glass tilting or jamming, affecting adjustment accuracy and service life; in order to achieve synchronous lifting on both sides, the relevant technologies usually need to be equipped with a dual-motor independent drive system, which not only increases cost and energy consumption, but also poses the risk of asynchronous movement on both sides; traditional rigid transmission mechanisms are prone to mechanical collision noises due to gaps or loose fits under bumpy vehicle conditions, and lack an effective dynamic compensation mechanism.

[0053] To address the aforementioned problems, this application provides an adjustment structure and windshield device. By linking multiple sliding members with a single drive bar, synchronous displacement of the sliding members can be achieved with a single drive, reducing structural complexity. Furthermore, the flexible drive bar can bypass obstacles or be arranged along complex paths, avoiding the rigid linear space requirements of gear and rack or connecting structures in transmission designs. In addition, the rigid connection between the drive bar and the sliding members eliminates the gaps inherent in traditional hinges or gear meshing, reducing motion deviations caused by wear and maintaining synchronization accuracy even after long-term use. This embodiment, through the direct linkage design between the drive bar and the sliding members, avoids the complex transmission mechanisms of traditional designs, achieving a minimalist structure while ensuring synchronization accuracy.

[0054] See Figure 1 and Figure 2 , Figure 1 This is a front view schematic diagram of an adjustment structure provided according to some embodiments of this application. Figure 2This is a perspective structural diagram of an adjustment structure provided according to some embodiments of the present application. One embodiment of the present application first provides an adjustment structure that can be fixed to the front end of a riding vehicle and is used to fix a windshield to adjust the windshield's raising or lowering. The adjustment structure may include a mounting base 100, a transmission assembly 200, a drive bar 300, and at least two sliding members 400.

[0055] The transmission assembly 200 is mounted on the mounting base 100; the drive bar 300 is connected to the transmission assembly 200 and is configured to move under the drive of the transmission assembly 200; all sliding members 400 are fixedly connected to the drive bar 300 so as to move synchronously to the target position under the drive of the drive bar 300.

[0056] Understandably, the mounting base 100, as the supporting base of the overall structure, can be arranged in front of the driver of the riding vehicle and fixedly connected to the vehicle body. It can be made of lightweight metal (such as aluminum alloy) or high-strength engineering plastic, and its surface is provided with mounting holes and guide rail 500 fixing positions.

[0057] The transmission assembly 200 is fixed on the mounting base 100 and may include a drive source (e.g., a motor or manual) and a power transmission mechanism. The drive source may be a DC motor, a stepper motor or a micro servo motor. The power transmission assembly may include a drive wheel 210, such as a worm gear or a pulley with a spiral groove, and a driven wheel 220, such as a fixed pulley block. The drive wheel 210 may be connected to an external handle (manual) or a drive motor 230 (e.g., a stepper motor or a DC motor) (electric) to drive the drive wheel 210 to rotate by external force.

[0058] The drive bar 300, connected to the transmission assembly 200, can be made of a flexible, high-tensile-strength material, such as steel wire rope, carbon fiber cable, or synchronous belt, but is not specifically limited thereto. The drive bar 300 forms a closed-loop transmission path with the driving wheel 210 and the driven wheel through a winding method. Each sliding member 400 (which can be a rigid slider or connecting block) can be fixedly connected to the drive bar 300 by riveting, snap-fitting, or bolting. To improve the stability of the sliding member 400's movement path, the sliding member 400 can be placed within the guide rail 500 on the mounting base 100. Furthermore, a low-friction coating can be added to the surface of the sliding member 400 to improve its smoothness of movement within the guide rail 500. In this embodiment, the sliding member 400 is used to connect the windshield, specifically to connect the windshield mounting bracket.

[0059] More specifically, in this embodiment, the output end of the transmission component 200 drives the drive bar 300 to move by rotation, and specific segments of the drive bar 300 are rigidly connected to the sliding member 400. The sliding member 400 is pulled by the drive bar 300 and moves synchronously to the target position along a preset path (usually a straight line), so as to realize the synchronous movement of two or more sliding members 400 through one power source.

[0060] Taking two sliding members 400 as an example, the two sliding members 400 can be set on the left and right sides of the mounting base 100, while the driving wheel 210 is set in the middle of the mounting base 100. A driven wheel 220 is set at the upper left, lower left, upper right, and lower right of the mounting base 100 (corresponding to the two ends of the guide rail 500). The drive bar 300 can be wound multiple times around the driving wheel 210, sequentially passing through the upper left, lower left, upper right, and lower right before returning to the driving wheel 210. That is, the winding of the drive bar 300 forms a bow shape (closed loop path), which can also be understood as a figure-eight rope winding pattern. When the drive bar 300 is pulled unidirectionally by the driving wheel 210, the sliding members 400 are pulled synchronously in the same direction by the pull of the drive bar 300. In other words, the above winding method allows the sliding members 400 on the left and right sides to rise or fall synchronously.

[0061] The fixed connection between the slider 400 and the drive bar 300 can adopt an anti-loosening design. For example, a crimp sleeve or a wedge joint can be used for fixing, but there are no specific restrictions.

[0062] The adjustment structure provided in this embodiment uses a single drive bar 300 to link multiple sliding members 400. Synchronous displacement of the multiple sliding members 400 can be achieved with a single drive, reducing structural complexity. Furthermore, the flexible drive bar 300 can bypass obstacles or be arranged along complex paths, avoiding the rigid linear space requirements of gear and rack or connecting structures in transmission designs. In addition, the rigid connection between the drive bar 300 and the sliding members 400 eliminates the gaps of traditional hinges or gear meshing, reducing motion deviations caused by wear and maintaining synchronization accuracy even after long-term use. This embodiment, through the direct linkage design between the drive bar 300 and the sliding members 400, avoids the complex transmission mechanisms of traditional designs, achieving a minimalist structure while ensuring synchronization accuracy.

[0063] Below, we will combine the appendix Figure 1 -Appendix Figure 7 The specific structure of the adjustment structure provided in the embodiments of this application will be described in detail.

[0064] like Figure 6 and Figure 7 As shown, Figure 6 This is a front view schematic diagram of the adjustment structure and target component provided according to some embodiments of this application. Figure 7This is a side view of the adjustment structure and target component provided according to some embodiments of this application. In some embodiments, the mounting base 100 is provided with at least two guide rails 500, and at least two sliders 400 are correspondingly disposed in the at least two guide rails 500. The sliders 400 are used to connect the target component 10. The at least two guide rails 500 are spaced apart along a first direction, and each guide rail 500 extends along a second direction intersecting the first direction.

[0065] Specifically, the first direction is defined as the horizontal direction, and the second direction is defined as the vertical direction perpendicular to the first direction, but no specific restrictions are imposed. In this embodiment, the two guide rails 500 can be arranged parallel and spaced apart on the mounting base 100, and the specific horizontal spacing can be set according to the size of the windshield, etc. The guide rails 500 can be integrally formed on the mounting base 100, or can be independently processed and fixed in the preset groove of the mounting base 100 by bolts, welding, etc., and no specific restrictions are imposed.

[0066] The inner surface of the guide rail 500 can be coated with a low-friction coating, such as Teflon, or an embedded roller guide can be used to reduce the movement resistance of the slider 400. The top of the slider 400 can be bolted to a windshield mounting bracket, which can be hinged or rigidly fixed to the windshield.

[0067] In this embodiment, the dual guide rail 500 layout can enhance structural stability, and the precise cooperation between the slider 400 and the guide rail 500 can ensure that the slider 400 can only move in a straight line along the second direction, ensuring that the windshield's lifting trajectory is not deviated and improving adjustment accuracy.

[0068] like Figure 2 and Figure 5 As shown, Figure 5 This is a front view of an adjustment structure (without the slider) provided according to some embodiments of this application. In some embodiments, the transmission assembly 200 may include a driving wheel 210 and a plurality of driven wheels 220. The driving wheel 210 is disposed on the mounting base 100, and the plurality of driven wheels 220 are disposed on the mounting base 100, with at least some of the driven wheels 220 disposed at the ends of the guide rail 500 along the second direction. A drive bar 300 is disposed around the driving wheel 210 and the plurality of driven wheels 220. The drive bar 300 includes a first portion and a second portion located on both sides of the driving wheel 210 along the first direction. The first portion connects to one of the two sliders 400, and the second portion connects to the other of the two sliders 400.

[0069] Understandably, the driving wheel 210 can be located in the middle of the mounting base 100 and connected to the output shaft of the drive motor 230 via a coupling. The driven wheels 220, acting as fixed pulleys, can be designed in a quantity of four, located at the upper and lower ends of the two guide rails 500 respectively (i.e., one at each end of each guide rail 500), and can be fixed to the mounting base 100 via bearings. Of course, the number of driven wheels 220 is not limited; transition wheels can be set at any position between the driving wheel 210 and either end of the guide rail 500 to provide auxiliary support for the drive bar 300.

[0070] For ease of description, the drive bar 300 is divided into two parts: a first part located to the left of the drive wheel 210 and a second part located to the right of the drive wheel 210. In reality, the drive bar 300 can be a closed rope. The first part is mainly used to connect the left sliding member 400, and the second part is mainly used to connect the right sliding member 400, so that synchronous movement of the left and right sliding members 400 can be achieved through a single transmission of the drive bar 300.

[0071] It should be noted that the aforementioned drive bar 300 may include, for example: Figure 5 The two sections shown are both used to be fixedly connected to the slider 400. Since the connection between the drive bar 300 and the slider 400 is a rigid connection, the rope connected to the slider 400 can be understood as a closed rope, thereby achieving synchronous movement under the drive of the drive wheel 210.

[0072] In this embodiment, the closed-loop transmission path constructed by the drive bar 300 can ensure the balance of driving force on both sides, and the pulley group can reduce the wear of the drive bar 300 and extend its service life.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments, a first driven wheel 221 and a second driven wheel 222 are provided at both ends of the guide rail 500 located on one side of the first part; a third driven wheel 223 and a fourth driven wheel 224 are provided at both ends of the guide rail 500 located on one side of the second part; wherein the first driven wheel 221 and the third driven wheel 223 are arranged along a first direction, and the second driven wheel 222 and the fourth driven wheel 224 are arranged along a first direction.

[0074] Understandably, the left guide rail 500 has a first driven wheel 221 (upper left) and a second driven wheel 222 (lower left) at its upper and lower ends, respectively, while the right guide rail 500 has a third driven wheel 223 (upper right) and a fourth driven wheel 224 (lower right) at its upper and lower ends, respectively. The first driven wheel 221 and the third driven wheel 223 are aligned horizontally (in the first direction), with a spacing equal to the spacing of the guide rails 500; the second driven wheel 222 and the fourth driven wheel 224 are also horizontally aligned.

[0075] The drive bar 300 extends symmetrically from the drive wheel 210 to the left and right sides, passing around the driven wheel of the same height to form a mirror layout, which can also be understood as a bow-shaped routing, to ensure that the left and right sliding parts 400 are subjected to uniform force.

[0076] In this embodiment, the symmetrical arrangement can eliminate the deviation of the driving force on one side, avoid jamming when the windshield is raised or lowered, and the horizontally aligned pulley group can simplify the installation and calibration process.

[0077] like Figure 2 and Figure 6 As shown, in some embodiments, the adjustment structure further includes a guide block 600, which is disposed on the mounting base 100 and located on one side of the drive wheel 210; the drive bar 300 is wound around the drive wheel 210 and passes sequentially through the first driven wheel 221, the second driven wheel 222, the guide block 600, the third driven wheel 223 and the fourth driven wheel 224 until it reaches the drive wheel 210; the moving direction of the portion of the drive bar 300 located between the first driven wheel 221 and the second driven wheel 222 is consistent with the moving direction of the portion of the drive bar 300 located between the third driven wheel 223 and the fourth driven wheel 224.

[0078] It is understood that, based on the above embodiment, the routing of the drive bar 300 is bow-shaped, meaning that the drive bars 300 converge at the drive wheel 210 located in the middle of the mounting base 100 to avoid interference during movement. Specifically, after the drive bar 300 is led out from the drive wheel 210, it first passes through the upper and lower driven wheels of the left guide rail 500, then passes through the guide block 600, then winds around the upper and lower driven wheels of the right guide rail 500, and finally returns to the drive wheel 210. The guide block 600 physically separates the left and right drive bars 300 to prevent tangling; at the same time, it forces the drive bars 300 to move in the same direction on both sides of the drive wheel 210.

[0079] The guide block 600 in this embodiment can not only eliminate the friction of the drive bars 300 crossing each other and improve the service life of the drive bars 300, but also reduce noise.

[0080] In one example, the guide block 600 has a guide groove on the side facing away from the drive wheel 210 to accommodate the drive bar 300 and to separate the portion of the drive bar 300 located at the drive wheel 210. Specifically, the guide groove on the side of the guide block 600 facing away from the drive wheel 210 can be a V-shaped or U-shaped groove, and a low-friction bushing can be embedded in the groove. In addition, the depth of the guide groove can be slightly larger than the diameter of the drive bar 300 to prevent the drive bar 300 from coming out.

[0081] In some embodiments, the outer circumferential surface of the drive wheel 210 is constructed with a helical groove, and the drive bar 300 is wound around the helical groove. Specifically, the helical groove can be a single-thread or multi-threaded thread, and the bottom of the groove is designed to be arc-shaped to match the diameter of the drive bar 300 (e.g., a steel wire rope), thereby increasing the contact area and friction.

[0082] In one example, the drive bar 300 includes a rope. Specifically, the drive bar 300 can be made of stainless steel wire rope or Kevlar fiber rope, etc., and there are no restrictions here.

[0083] In one example, the driven pulley includes a fixed pulley. Specifically, the driven pulley can be a nylon fixed pulley with a deep groove ball bearing, but there is no particular limitation.

[0084] In this embodiment, the transmission assembly 200 also includes a manual adjustment lever, such as the gear shifter of a multi-speed bicycle, to control the sliding member 400 to rise or fall by manually adjusting the drive wheel 210.

[0085] In addition to the manual adjustment method mentioned above, there is also an electric adjustment method, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of the rear structure of the adjustment structure provided according to some embodiments of this application. In some embodiments, the transmission assembly 200 further includes a drive motor 230, the output end of which is connected to the drive wheel 210, and the drive motor 230 is configured to drive the drive wheel 210 to rotate forward or in reverse.

[0086] Specifically, it can be directly connected to the drive wheel 210 shaft via a coupling, and the drive motor 230 can have a built-in Hall sensor to feed back the speed signal to the control unit, thereby achieving closed-loop speed regulation.

[0087] like Figure 2 As shown, in some embodiments, the mounting base 100 includes a mounting body 110 and a pretensioning assembly 120, the pretensioning assembly 120 being movably disposed on the mounting body 110 and located at at least one end of each guide rail 500 along a second direction, and at least a portion of the driven wheel being mounted on the pretensioning assembly 120.

[0088] It is understood that the aforementioned drive wheel 210 is mounted on the mounting body 110. In order to achieve pre-tensioning of the drive bar 300 and reach the predetermined pre-tensioning force, the driven wheel used to wrap around the drive bar 300 needs to be set on the pre-tensioning assembly 120. By adjusting the pre-tensioning assembly 120, the relative position of the driven wheel with respect to the mounting body 110 is indirectly adjusted to achieve pre-tensioning of the drive bar 300.

[0089] like Figure 2As shown, in some embodiments, the preload assembly 120 includes a support frame 121, a preload bolt 122, and a fastening bolt 123. The preload bolt 122 connects the support frame 121 and the mounting body 110 to adjust the relative position of the support frame 121 and the mounting body 110 in a second direction. The fastening bolt 123 is configured to fix the support frame 121 and the mounting body 110 after the support frame 121 has been adjusted into place.

[0090] Specifically, the support frame 121 can be moved by rotating the pre-tightening bolt 122. The magnitude of the pre-tightening force is determined by judging the torque of the pre-tightening bolt 122. When the drive bar 300 is tightened, the position of the support frame 121 is fixed by locking the fastening bolt 123, thereby achieving the pre-tightening of the drive bar 300.

[0091] In this embodiment, a pre-tightening component 120 can be provided at one end of each of the two guide rails 500 along the second direction, thereby achieving synchronous adjustment of the left and right sides.

[0092] like Figure 4 As shown, Figure 4 This is a front view of an adjustment structure (mounting bracket and guide rail) provided according to some embodiments of this application. In some embodiments, each guide rail 500 is provided with a positioning hole 510, and a plurality of positioning holes 510 are arranged sequentially along a first direction; the positioning holes 510 are configured to fix the sliding member 400 and the mounting base 100 during the pre-tightening of the drive bar 300.

[0093] It is understandable that, in order to ensure that the sliding parts 400 on the left and right sides remain on the same horizontal line during the adjustment process of the pre-tightening assembly 120, a positioning hole 510 is constructed on the guide rail 500, and a limiting hole adapted to the positioning hole 510 is provided on the sliding part 400. Before pre-tightening, the sliding part 400 is fixed in a predetermined position on the guide rail 500 by passing a screw through the limiting hole and the positioning hole 510. That is, in the pre-tightened state, the sliding part 400 cannot slide relative to the guide rail 500.

[0094] like Figure 1 As shown, in some embodiments, micro switches 800 are provided at both ends of any guide rail 500 along the second direction. When the slider 400 rises or falls and acts on the triggering mechanism of the micro switch, its internal contacts will change from open to closed, or from closed to open, thereby controlling the on and off of the circuit, which is beneficial to realize the signal transmission of the slider 400 rising or falling to the position.

[0095] In addition to the electric limit switch method mentioned above, other methods include, for example... Figure 1As shown, in some embodiments, each guide rail 500 has a limiting component 900 at at least one end along the second direction. Specifically, the limiting component 900 in this embodiment can be a mechanical limiting baffle, and the extreme limiting baffle can be set at both ends of each guide rail 500 along the second direction to prevent the sliding component from dislodging from the guide rail 500 and ensure the reliability of the adjustment structure.

[0096] In one example, the adjustment structure also includes an elastic element (not shown), which is capable of deforming along a first direction, with one end of the elastic element confined to the slider 400 and the other end confined to the guide rail 500.

[0097] Specifically, to ensure that the slider 400 moves smoothly within the guide rail 500, the slider 400 and the guide rail 500 are fitted with a clearance. To prevent the slider 400 from wobbling in the first direction within the guide rail 500, an elastic element, namely a compression spring, is provided between the two to improve the stability of the slider 400's movement.

[0098] Based on the same inventive concept, this application also provides a windshield device, which may include the adjustment structure of the above embodiment and a glass assembly. The glass assembly is mounted on at least two sliding members 400 of the adjustment structure and moves synchronously under the action of the drive bar 300.

[0099] It is understood that the glass assembly in this embodiment can be understood as a single windshield. The glass assembly can be fixed to the corresponding sliding member 400 by bolts, clips, or adhesives, and moves synchronously with the sliding member 400. When the drive motor 230 starts, the drive bar 300 pulls all the sliding members 400 to move synchronously along the guide rail 500, driving the glass assembly to move at the same speed and direction. Through the linear constraint of the guide rail 500 and the closed-loop transmission of the drive bar 300, it is ensured that there is no phase difference when the glass assembly is raised, lowered, or unfolded, avoiding glass tilting or offset due to asynchrony.

[0100] The adjustment structure provided in this embodiment improves the synchronization, reliability and spatial adaptability of the adjustment structure by refining the layout of the guide rail 500, optimizing the transmission path, pre-tensioning adjustment and limiting design, so as to fully cover the diverse needs of riding vehicles.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
