Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically to a stable motorcycle windshield lifting device. Background Technology

[0002] During motorcycle riding, the windshield serves as a crucial protective component, effectively blocking airflow, dust, and gravel from harming the rider. It also reduces wind noise, enhancing riding comfort and safety, hence its widespread use on various motorcycles. As users' demands for a superior riding experience continue to rise, height-adjustable motorcycle windshields are gradually becoming the mainstream feature. Users can flexibly adjust the windshield height according to different riding speeds, weather conditions, and their own height requirements to achieve optimal protection and visibility.

[0003] Currently, most retractable motorcycle windshields on the market use a direct drive mechanism. This means that linear drive components such as cylinders and electric actuators are directly connected to the glass bracket, and the extension and retraction of these components raises and lowers the glass bracket and windshield. However, this direct drive structure has significant stability defects in actual use: because the glass bracket relies solely on the drive component for support and guidance, lacking additional limiting and guiding mechanisms, the windshield is subjected to strong airflow impacts when the motorcycle is traveling at high speeds or encountering strong winds. In such situations, the glass bracket, connected only by the drive component, is prone to wobbling and shifting. This not only affects the windshield's protective effect, allowing airflow to pass through gaps created by the wobbling and reducing protection for the rider, but can also cause collisions and friction between the windshield and other motorcycle components, producing abnormal noises or even damaging parts, seriously affecting riding safety and comfort.

[0004] Furthermore, in existing direct-drive structures, the drive element must simultaneously perform both driving and guiding functions, resulting in a prolonged state of uneven stress. This easily leads to accelerated wear of the drive element, shortening its lifespan and increasing maintenance costs and replacement frequency for users. Simultaneously, during windshield raising and lowering, the lack of a stable guiding mechanism causes the lifting and lowering action to be prone to jamming and unevenness, affecting the user's operating experience. Therefore, how to design a windshield raising and lowering device that can effectively improve the stability of motorcycle windshield raising and lowering, enhance protective effects, extend component lifespan, and improve the operating experience has become an urgent problem to be solved in the current motorcycle parts industry.

[0006] The technical solution adopted by this utility model is: a stable motorcycle windshield lifting device, comprising:

[0007] The mounting bracket has a mounting part at the bottom and an arc-shaped guide arm at the top, and a guide lifting groove is provided along the length of the arc-shaped guide arm;

[0009] The drive device is movably coupled with the mounting bracket;

[0010] The transmission unit has one end rotatably engaged with the mounting bracket and the other end rotatably engaged with the second connecting arm. The output end of the drive device rotatably engages with the transmission unit.

[0011] A further feature of this application is that a number of reinforcing strips are spaced apart between the arc-shaped guide arm and the mounting bracket.

[0012] A further feature of this application is that a sliding sleeve is fitted inside the guide lifting groove.

[0013] The present application further provides that: a connecting sleeve is provided on the outer side of the first connecting arm, a cover is fitted on the connecting sleeve, one end of the connecting shaft is fixed to the cover by bolts, and the other end of the connecting shaft is provided with an anti-detachment step.

[0014] A further feature of this application is that a pre-tensioning spring is fitted on the connecting shaft, with one end of the pre-tensioning spring abutting against the cover and the other end abutting against the arc-shaped guide arm.

[0015] The present application further provides that: the upper surface of the glass bracket is provided with a mounting surface for installing the windshield glass, and the mounting surface is provided with mounting holes.

[0016] The present application further specifies that the transmission part includes an outer frame and an inner block, the inner block is fixedly connected to the outer frame, the two ends of the outer frame have rotating holes, and the inner block is provided with a rotating seat.

[0017] The present application further specifies that the driving device includes a motor, a reduction gearbox connected to the output end of the motor, and an output worm gear driven by the reduction gearbox, wherein the top of the output worm gear is rotatably engaged with the rotating seat.

[0018] The present application further includes a motor bracket and a connecting bracket, wherein a rotational space for relative rotation with respect to the motor is formed between the motor bracket and the connecting bracket, the motor bracket and the connecting bracket are fixedly connected by bolts, and the bottom of the connecting bracket extends a connecting foot that fits against the above-mentioned mounting part, and the connecting foot and the mounting part are provided with concentric mounting holes.

[0019] The beneficial effects of this utility model are:

[0020] 1. Improved Stability: By setting a guide lifting groove on the arc-shaped guide arm of the mounting bracket, and allowing the glass bracket to slide in conjunction with the guide lifting groove via a connecting shaft, a stable limiting guide structure is provided for the lifting of the glass bracket. During the windshield lifting process, the glass bracket can slide precisely along the guide lifting groove, avoiding problems such as lifting jamming and deviation. At the same time, when the motorcycle is traveling at high speed or encountering strong winds, the guide lifting groove can effectively constrain the glass bracket, offset the impact of airflow on the windshield, reduce the swaying amplitude of the glass bracket, and prevent the windshield from colliding and rubbing with other parts of the motorcycle, causing abnormal noise or damage. This fundamentally solves the defect of poor stability in the existing structure and provides riders with a safer riding environment.

[0021] 2. Optimized component stress state and extended service life: In existing direct drive structures, the drive element must simultaneously undertake the functions of driving and supporting / guiding, resulting in a long-term state of unbalanced stress, which easily accelerates wear. The guide lifting groove of this application can share the support and guidance of the glass bracket, effectively reducing the wear of the drive element and extending its service life.

[0022] 3. Smooth lifting and lowering, enhancing the user experience: The design of the guide lifting groove ensures that the wave bracket lifts and lowers smoothly along the preset trajectory, improving the stability of lifting and lowering.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0034] This utility model provides a stable motorcycle windshield lifting device.

[0035] In this embodiment, refer to Figure 1-6 The stable motorcycle windshield lifting device includes:

[0036] Mounting bracket 1, the mounting bracket 1 has a mounting part 2 at the bottom and an arc-shaped guide arm 3 at the top, and a guide lifting groove 4 is provided along the length direction of the arc-shaped guide arm 3;

[0037] A glass support 5 is provided with a first connecting arm 6 and a second connecting arm 7 on both sides. A connecting shaft 8 is connected to the first connecting arm 6, and the connecting shaft 8 is slidably engaged with the guide lifting groove.

[0038] Drive device 9, which is fixedly connected to the mounting bracket;

[0039] The transmission unit 10 has one end rotatably engaged with the mounting bracket and the other end rotatably engaged with the second connecting arm. The output end of the drive device is rotatably engaged with the transmission unit.

[0040] In the above technical solution, the mounting bracket, through the guide lifting groove of the arc-shaped guide arm, forms a sliding engagement with the connecting shaft of the first connecting arm of the glass bracket; the drive device, with the help of the transmission unit (both ends of which are rotatably engaged with the mounting bracket and the second connecting arm of the glass bracket respectively), converts linear power into the arc-shaped lifting motion of the glass bracket along the guide lifting groove. The setting of the guide lifting groove provides a stable guiding trajectory for the glass bracket, avoiding lifting deviation and jamming; it also distributes the force on the drive device, solving the problem of poor stability of existing direct drive structures, and making the windshield less prone to shaking during strong winds or high-speed driving.

[0041] Specifically, several reinforcing strips 11 are provided at intervals between the arc-shaped guide arm and the mounting bracket.

[0042] In this embodiment, several reinforcing strips are added between the arc-shaped guide arm and the mounting bracket to enhance the connection strength and reduce the deformation of the guide arm under stress. This improves the structural rigidity of the arc-shaped guide arm, preventing it from bending during long-term use or under stress, ensuring the accurate trajectory of the guide lifting groove, and further guaranteeing the stability of the windshield lifting.

[0043] Specifically: The guide lifting groove is fitted with a sliding sleeve 12.

[0044] In this embodiment, a sliding sleeve is fitted inside the guide lifting groove to reduce direct friction between the connecting shaft and the groove wall and reduce sliding resistance.

[0045] Specifically: a connecting sleeve 13 is provided on the outer side of the first connecting arm, a cover 14 is fitted on the connecting sleeve 13, one end of the connecting shaft is fixed to the cover by bolts, and the other end of the connecting shaft is provided with an anti-detachment step 15.

[0046] In this embodiment, a connecting sleeve is provided on the outside of the first connecting arm, and a cover is fitted onto the connecting sleeve. One end of the connecting shaft is fixed to the cover with bolts, and the other end is provided with an anti-detachment step to restrict the connecting shaft from coming out of the guide lifting groove, thereby avoiding the risk of the windshield falling off. At the same time, the cover covers the installation part to reduce the entry of dust and rainwater and protect the sliding structure.

[0047] Specifically: a pre-tension spring 16 is fitted on the connecting shaft, one end of the pre-tension spring abuts against the cover, and the other end abuts against the arc-shaped guide arm.

[0048] In this embodiment, a pre-tensioning spring is fitted onto the connecting shaft, with both ends abutting against the cover and the arc-shaped guide arm, respectively, to provide continuous pre-tensioning force to the connecting shaft and eliminate sliding gaps. This prevents the connecting shaft and the guide lifting groove from shaking or making abnormal noises due to gaps, improves the smoothness of windshield lifting, and enhances structural stability during driving.

[0049] Specifically: the upper surface of the glass bracket is provided with a mounting surface 17 for installing the windshield glass, and the mounting surface 17 is provided with mounting holes 18.

[0050] In this embodiment, the upper surface of the glass bracket is provided with a mounting surface and mounting holes. Bolts or other connectors are passed through the mounting holes to fix the windshield to the mounting surface. This achieves a stable connection between the windshield and the bracket, facilitating glass removal and replacement, adapting to different windshield specifications, and improving the device's versatility.

[0051] Specifically: the transmission part includes an outer frame 19 and an inner block 20. The inner block 20 is fixedly connected inside the outer frame 19. The outer frame 19 has rotating holes 21 at both ends. The inner block is provided with a rotating seat 22.

[0052] In this embodiment, the transmission unit consists of an outer frame (with rotating holes at both ends for rotatable connection with the mounting bracket and glass bracket) and an inner block. The outer frame ensures structural strength, and the rotating seat of the inner block is used to dock with the drive device. This ensures precise rotational engagement at both ends of the transmission unit and provides a stable connection point for the drive device, preventing deformation of the transmission unit during power transmission and ensuring power conversion efficiency.

[0053] Specifically: The drive device includes a motor 23, a gearbox connected to the output end of the motor, and an output worm gear 24 driven by the gearbox 29. The top of the output worm gear 24 is rotatably engaged with the rotating seat.

[0054] In this embodiment, the drive device drives an output worm gear via a motor. The output worm gear engages with the rotating seat of the embedded block in the transmission unit, converting the rotational power of the motor into linear thrust / pull force, which drives the transmission unit to move in a linear reciprocating motion. This achieves electric and precise control of the windshield lifting, and compared to cylinder drive, it is easier to adjust the lifting speed and position, improving operational convenience.

[0055] The gearbox is an existing worm gear reducer, which realizes linear transmission of the extension and retraction of the output worm.

[0056] Specifically, it also includes a motor bracket 25 and a connecting bracket 26. A rotation space 30 for relative rotation with the motor is formed between the motor bracket and the connecting bracket. The motor bracket and the connecting bracket are fixed together by bolts. The bottom of the connecting bracket extends with a connecting foot 27 that fits into the mounting part. The connecting foot 27 and the mounting part are provided with concentric mounting holes 28.

[0057] In this embodiment, the motor is bolted to the connecting bracket via a motor bracket. The connecting feet of the connecting bracket fit snugly against the mounting portion of the mounting bracket, and the entire assembly is fixed using concentric mounting holes, ensuring the relative position of the motor and the mounting bracket is stable. Furthermore, the rotation space provides installation space for the motor while also cooperating with the motor's rotation.

[0058] The driving principle of this application is as follows: the drive device is movably coupled with the mounting bracket, and its output worm gear is rotatably coupled with the rotating seat of the inner block of the transmission part (the motor is connected to the output worm gear through a reduction gearbox, converting the rotational motion of the motor into the linear motion of the output worm gear). After the motor starts, it drives the output worm gear to move, converting the rotational power into linear thrust or pull force, which drives the transmission part to move.

[0059] Because one end of the transmission unit is rotatably engaged with the mounting bracket and the other end is rotatably engaged with the second connecting arm of the glass bracket, the transmission unit rotates around the mounting bracket under the action of linear driving force, while simultaneously pushing or pulling the glass bracket.

[0060] Furthermore, because the connecting shaft of the first connecting arm of the glass bracket slides in conjunction with the guide lifting groove of the arc-shaped guide arm of the mounting bracket, when the glass bracket is subjected to the force of the transmission part, it will smoothly rise and fall along the arc-shaped trajectory of the guide lifting groove, ultimately achieving the height adjustment of the windshield.

[0061] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
