Description

Technical Field

[0001] The present application relates to the technical field of windshield adjustment, and in particular to an adjustment structure and a windshield device. Background Art

[0002] Currently, windshield regulators for riding vehicles (such as motorcycles and electric scooters) generally utilize a single motor driving a single lifting guide rail. Specifically, this traditional solution typically uses a single drive motor to independently control a rack-and-pinion mechanism or four-bar linkage on one side, thereby driving the windshield's upward and downward adjustment.

[0003] However, this type of structure has significant drawbacks. When using a rack-and-pinion mechanism, the upward and downward movement of the rack requires a large space, which restricts the layout of other components within the vehicle and hinders the design of the front end, making it difficult to meet the demands of modern vehicles for compact layouts and aesthetically pleasing styling. Furthermore, when using a four-bar linkage, due to its inherent mechanical characteristics, the windshield cannot be raised or lowered in a straight line. This can lead to deviations in the windshield's trajectory during the raising and lowering process, affecting the accuracy and stability of the adjustment. Summary of the Invention

[0024] And / or, a guide groove is configured on a side of the guide block facing away from the driving wheel to accommodate the driving bar and separate a portion of the driving bar located at the driving wheel.

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

[0026] In one embodiment, the mounting seat includes a mounting body and a pre-tightening assembly, the pre-tightening assembly is movably mounted on the mounting body and is located at at least one end of each guide rail along the second direction, and at least part of the driven wheel is mounted on the pre-tightening assembly.

[0051] As mentioned in the background art, in order to adjust the windshield of a riding vehicle, a traditional solution is usually to independently control a rack and pinion mechanism or a four-bar linkage mechanism on one side through a drive motor, thereby driving the windshield to be raised and lowered.

[0052] However, the above structure has the following problems: the rack and pinion mechanism relies on the up and down linear motion of the rack, and its travel direction occupies a large longitudinal space, which limits the layout of the front parts of the vehicle and has a negative impact on the freedom of vehicle styling design; the four-bar linkage is prone to nonlinear trajectory deviations during movement, making it difficult to ensure that the windshield rises and falls along a vertical line. Long-term use can easily cause the glass to tilt or get stuck, affecting the adjustment accuracy and service life; in order to achieve synchronous lifting of the left and right sides, related technologies usually require a dual-motor independent drive system, which not only increases costs 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 clearance or loose fit under bumpy vehicle conditions, and lack an effective dynamic compensation mechanism.

[0053] Based on the above-mentioned problems, the embodiments of the present application provide an adjustment structure and a windshield device, which links multiple sliding parts through a single drive bar. Only a single drive is required to achieve the synchronous displacement of multiple sliding parts, which is conducive to reducing the complexity of the structure. In addition, the flexible drive bar can bypass obstacles or be arranged along complex paths, which can avoid the rigid requirements of the gear rack or connection structure for straight space in the transmission design. In addition, the rigid connection between the drive bar and the sliding part can eliminate the gap of the traditional hinge or gear meshing, reduce the motion deviation caused by wear, and maintain the synchronization accuracy after long-term use. This embodiment avoids the complex transmission mechanism in the traditional design through the direct linkage design of the drive bar and the sliding part, and realizes a minimalist structure while ensuring the synchronization accuracy.

[0054] See Figure 1 and Figure 2 , Figure 1 This is a schematic front view of the structure of the adjustment structure provided according to some embodiments of the present application. Figure 2This is a schematic diagram of a three-dimensional structure 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 used to secure a windshield to adjust the windshield's position upward or downward. 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 arranged on the mounting base 100; the drive bar 300 is connected to the transmission assembly 200, and the drive bar 300 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] It can be understood that the mounting seat 100, as the supporting base of the overall structure, can be arranged in a position 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 has mounting holes and guide rail 500 fixing positions on the surface.

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

[0058] The drive bar 300 connected to the transmission assembly 200 can be made of a flexible, high-tensile material, such as a steel wire rope, carbon fiber cable, or synchronous belt, but this is not a specific limitation. The drive bar 300 is wound around the driving pulley 210 and the driven pulley to form a closed-loop transmission path. Each slider 400 (which can be a rigid slider or connecting block) can be fixedly connected to the drive bar 300 by riveting, snapping, or bolting. To improve the stability of the slider's 400 movement path, the slider 400 can be positioned within a guide rail 500 on the mounting base 100, and a low-friction coating can be applied to the surface of the slider 400 to enhance its smooth movement within the guide rail 500. In this embodiment, the slider 400 is used to connect to a windshield, specifically to a windshield mounting bracket.

[0059] More specifically, in this embodiment, the output end of the transmission assembly 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 along a preset path (usually a straight line) to the target position, thereby realizing the synchronous control of the synchronous movement of two or more sliding members 400 through a single power source.

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

[0061] The fixed connection between the sliding member 400 and the driving bar 300 may be designed to prevent loosening, for example, a crimping sleeve or a wedge joint may be used for fixation, but this is not particularly limited.

[0062] The adjustment structure provided in the embodiment of the present application links multiple sliding members 400 through a single drive bar 300, and only a single drive is required to achieve the synchronous displacement of multiple sliding members 400, which is conducive to reducing the complexity of the structure. In addition, the flexible drive bar 300 can bypass obstacles or be arranged along complex paths, which can avoid the rigid requirements of the gear rack or connection structure for linear space in the transmission design. In addition, the rigid connection between the drive bar 300 and the sliding member 400 can eliminate the gap in the traditional hinge or gear meshing, reduce the movement deviation caused by wear, and maintain synchronization accuracy after long-term use. This embodiment avoids the complex transmission mechanism in the traditional design through the direct linkage design of the drive bar 300 and the sliding member 400, while ensuring synchronization accuracy, achieving a minimalist structure.

[0063] Below, we will combine the Figure 1 -Attached Figure 7 The specific structure of the regulating structure provided in the embodiment of the present application is described in detail.

[0064] like Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the front view structure of the adjustment structure and the target part provided according to some embodiments of the present application. Figure 7This figure shows a side view of an adjustment structure and a target object according to some embodiments of the present application. In some embodiments, the mounting base 100 is provided with at least two guide rails 500, and at least two sliding members 400 are disposed within the at least two guide rails 500 in a one-to-one correspondence. The sliding members 400 are used to connect to the target object 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 that intersects the first direction.

[0065] Specifically, the first direction is defined as the horizontal direction, while the second direction is defined as the vertical direction perpendicular to the first direction, but this is not a specific limitation. In this embodiment, the two guide rails 500 can be arranged parallel to and spaced apart from each other on the mounting base 100. The specific spacing along the horizontal direction can be set based on, for example, the size of the windshield. The guide rails 500 can be integrally formed on the mounting base 100, or independently machined and secured to a predetermined groove of the mounting base 100 via bolts, welding, or other means, without specific limitation.

[0066] The inner surface of the guide rail 500 can be provided with a low friction coating, such as Teflon, or embedded with a roller slide rail to reduce the movement resistance of the sliding member 400. The top of the sliding member 400 can be connected to the windshield mounting bracket by bolts, and the glass bracket 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 fit between the sliding member 400 and the guide rail 500 can enable the sliding member 400 to move linearly only along the second direction, ensuring that the lifting and lowering trajectory of the windshield is not offset and improving the adjustment accuracy.

[0068] like Figure 2 and Figure 5 As shown, Figure 5 This is a schematic front view of an adjustment structure (excluding the sliding member) provided according to some embodiments of the present application. In some embodiments, the transmission assembly 200 may include a driving wheel 210 and multiple driven wheels 220. The driving wheel 210 is disposed on the mounting base 100, and the multiple 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 surrounds the driving wheel 210 and the multiple driven wheels 220. The drive bar 300 includes a first portion and a second portion located on either side of the driving wheel 210 along the first direction. The first portion is connected to one of the two sliding members 400, and the second portion is connected to the other of the two sliding members 400.

[0069] It is understood that the driving wheel 210 can be disposed 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, serving as fixed pulleys, can be designed to be four in number, located at the upper and lower ends of the two guide rails 500 (i.e., one at each end of each guide rail 500), and can be fixed to the mounting base 100 via bearings. Of course, there is no limit to the number of driven wheels 220, and a transition wheel can be provided 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, namely, a first part located to the left of the driving wheel 210 and a second part located to the right of the driving wheel 210. In practice, the drive bar 300 can be a closed rope, with the first part primarily connected to the left slider 400 and the second part primarily connected to the right slider 400. This allows for synchronous movement of the left and right sliders 400 through a single transmission of the drive bar 300.

[0071] It should be noted that the driving bar 300 may include: Figure 5 The two sections shown have their ends fixedly connected to the sliding member 400. Since the connection between the driving bar 300 and the sliding member 400 is a rigid connection, the rope connected to the sliding member 400 can be understood as a closed rope, thereby achieving synchronous movement driven by the driving wheel 210.

[0072] In this embodiment, the closed-loop transmission path constructed by the driving bar 300 can ensure the balance of driving force on both sides, and the arrangement of the pulley assembly can reduce the wear of the driving 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 the first direction, and the second driven wheel 222 and the fourth driven wheel 224 are arranged along the first direction.

[0074] It is understood that the left guide rail 500 is provided with a first driven wheel 221 (upper left) and a second driven wheel 222 (lower left), respectively, at its upper and lower ends. The right guide rail 500 is provided with a third driven wheel 223 (upper right) and a fourth driven wheel 224 (lower right), 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 aligned horizontally.

[0075] The driving bar 300 extends symmetrically from the driving wheel 210 to the left and right sides, bypassing the driven wheels at the same height, forming a mirror layout, which can also be understood as a bow-tie-shaped wiring to ensure that the left and right sliding members 400 are evenly stressed.

[0076] The symmetrical arrangement in this embodiment can eliminate unilateral driving force deviation and avoid jamming when the windshield is raised or lowered, and the horizontally aligned pulley assembly 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 provided on the mounting seat 100 and is located on one side of the driving wheel 210; the driving bar 300 is wound around the driving wheel 210 and passes 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 in sequence until it reaches the driving wheel 210; the moving direction of the portion of the driving 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 driving 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 drive bar 300 is arranged in a bow-tie pattern. Specifically, the drive bar 300 intersects at the driving wheel 210 located in the middle of the mounting base 100 to prevent interference between the drive bars 300 during movement. Specifically, after exiting the driving wheel 210, the drive bar 300 first passes over the upper and lower driven wheels of the left guide rail 500, then through the guide block 600, then around the upper and lower driven wheels of the right guide rail 500, and finally returns to the driving wheel 210. The guide block 600 physically separates the left and right drive bars 300 to prevent entanglement and forces the drive bars 300 to move in the same direction on both sides of the driving wheel 210.

[0079] The provision of the guide block 600 in this embodiment can not only eliminate the friction caused by the intersection of the driving bars 300 and increase the service life of the driving bars 300 , but also reduce noise.

[0080] In one example, a guide groove is configured on the side of the guide block 600 facing away from the driving wheel 210 to accommodate the drive bar 300 and separate the portion of the drive bar 300 located near the driving wheel 210. Specifically, the guide groove on the side of the guide block 600 facing away from the driving wheel 210 can be V-shaped or U-shaped, and a low-friction bushing can be embedded in the groove. Furthermore, the depth of the guide groove can be slightly greater than the diameter of the drive bar 300 to prevent the drive bar 300 from dislodging.

[0081] In some embodiments, the outer surface of the driving wheel 210 is configured with a spiral groove, within which the drive bar 300 is wound. Specifically, the spiral groove can be a single-thread or multi-thread thread, with the bottom of the groove designed to be circular, matching the diameter of the drive bar 300 (e.g., a wire rope), thereby increasing contact area and friction.

[0082] In one example, the drive bar 300 includes a rope. Specifically, the drive bar 300 can be made of a stainless steel wire rope or a Kevlar fiber rope, etc., which is not limited here.

[0083] In one example, the driven wheel includes a fixed pulley. Specifically, the driven wheel can be a nylon fixed pulley with a deep groove ball bearing, which is not particularly limited.

[0084] In this embodiment, the transmission assembly 200 further includes a manual adjustment handle, such as a speed adjuster of a speed-changing bicycle, so as to control the sliding member 400 to rise or fall by manually adjusting the driving wheel 210 .

[0085] In addition to the above manual adjustment method, it can also be an electric adjustment method, such as Figure 3 As shown, Figure 3 Schematic diagram of the back structure of the adjustment structure provided according to some embodiments of the present application. In some embodiments, the transmission assembly 200 further includes a drive motor 230, the output end of the drive motor 230 is connected to the driving wheel 210, and the drive motor 230 is configured to drive the driving wheel 210 to rotate forward or reverse.

[0086] Specifically, the drive motor 230 may be directly connected to the driving wheel 210 through a coupling, and a Hall sensor may be built into the drive motor 230 to feed back a speed signal to the control unit to achieve closed-loop speed regulation.

[0087] like Figure 2 As shown, in some embodiments, the mounting seat 100 includes a mounting body 110 and a pre-tightening assembly 120. The pre-tightening assembly 120 is movably disposed on the mounting body 110 and is located at at least one end of each guide rail 500 along the second direction, and at least part of the driven wheel is mounted on the pre-tightening assembly 120.

[0088] It can be understood that the above-mentioned driving wheel 210 is installed on the mounting body 110, and in order to pre-tighten the driving bar 300 to achieve a predetermined pre-tightening force, it is necessary to set the driven wheel used to wind the driving bar 300 on the pre-tightening component 120. By adjusting the pre-tightening component 120, the relative position of the driven wheel with respect to the mounting body 110 is indirectly adjusted to achieve pre-tightening of the driving bar 300.

[0089] like Figure 2As shown, in some embodiments, the pre-tightening assembly 120 comprises a support frame 121, a pre-tightening bolt 122 and a fastening bolt 123, the pre-tightening 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 the second direction; the fastening bolt 123 is configured to fix the support frame 121 and the mounting body 110 after the support frame 121 is adjusted in place.

[0090] Specifically, the support frame 121 can be pushed to move by the rotation of the pre-tightening bolt 122, the size of the pre-tightening force can be determined by judging the torque of the pre-tightening bolt 122, and when the driving bar 300 is tightened, the position of the support frame 121 is fixed by locking the fastening bolt 123, thereby realizing the pre-tightening of the driving bar 300.

[0091] In the present embodiment, one pre-tightening assembly 120 can be arranged at each end of the two guide rails 500 in the second direction, thereby realizing the synchronous adjustment of the left and right sides.

[0092] As shown, Figure 4 As shown, Figure 4 A front view structural schematic diagram of the adjustment structure (mounting frame and guide rail) provided according to some embodiments of the present application is shown. In some embodiments, each guide rail 500 is configured with a positioning hole 510, and a plurality of positioning holes 510 are arranged in sequence along the first direction; the positioning hole 510 is configured to fix the sliding member 400 and the mounting seat 100 during the process of pre-tightening the driving bar 300.

[0093] It can be understood that, in order to ensure that the left and right sides of the sliding member 400 remain in the same horizontal line during the adjustment process of the above-mentioned pre-tightening assembly 120, the positioning hole 510 is configured on the guide rail 500, and the limiting hole matched with the positioning hole 510 is arranged on the sliding member 400, before pre-tightening, the sliding member 400 is fixed at the predetermined position of the guide rail 500 by screwing through the limiting hole and the positioning hole 510, that is, the sliding member 400 cannot slide relative to the guide rail 500 in the pre-tightening state.

[0094] As shown, Figure 1 As shown, in some embodiments, the micro switch 800 is arranged at both ends of any guide rail 500 in the second direction, when the sliding member 400 rises or descends to act on the trigger mechanism of the micro switch, the internal contact will change from the open state to the closed state, or from the closed state to the open state, thereby controlling the on-off of the circuit, which is conducive to realizing the signal transmission of the sliding member 400 rising or descending to the position.

[0095] In addition to the above-mentioned electric limiting mode, it can also be, as Figure 1As shown, in some embodiments, a limit assembly 900 is provided at at least one end of each guide rail 500 along the second direction. Specifically, the limit assembly 900 in this embodiment can be a mechanical limit baffle. The limit baffle can be provided at both ends of each guide rail 500 along the second direction to prevent the sliding assembly from falling out of the guide rail 500, thereby ensuring the reliability of the adjustment structure.

[0096] In one example, the adjustment structure further includes an elastic member (not shown), which is deformable along a first direction, with one end of the elastic member being limited to the sliding member 400 and the other end being limited to the guide rail 500 .

[0097] Specifically, to ensure that the sliding member 400 moves smoothly in the guide rail 500, the sliding member 400 and the guide rail 500 are clearance-matched, and to prevent the sliding member 400 from shaking along the first direction in the guide rail 500, an elastic member is provided between the two, and the elastic member is also a compression spring, which improves the smoothness of the movement of the sliding member 400.

[0098] Based on the same inventive concept, the present application also provides a windshield device, which may include the adjustment structure of the above-mentioned embodiment and a glass assembly. The glass assembly is mounted on at least two sliding members 400 of the adjustment structure and is driven by a drive bar 300 to move the glass assembly synchronously.

[0099] It is understood that the glass assembly in this embodiment can be understood as a complete 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 is activated, 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. The linear constraint of the guide rail 500 and the closed-loop transmission of the drive bar 300 ensure that there is no phase difference when the glass assembly is raised, lowered, or extended, thus preventing glass tilt or deviation caused by asynchronous operation.

[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-tightening adjustment and limit design, so as to fully cover the diverse needs of riding vehicles.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
