Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically a screw-type linear output mechanism for raising and lowering motorcycle windshields. Background Technology

[0002] In the field of motorcycle riding, the windshield is a key protective component, and its height adjustment function directly affects the comfort and safety of the rider. The linear output mechanism used to drive the windshield to rise and fall is the core component to realize this function.

[0003] Existing linear output mechanisms for motorcycle windshield lifts have several shortcomings: some use hydraulic drive structures, which are not only bulky and poorly adaptable, but also prone to leakage and have high maintenance costs; most mechanical drive structures use a design with ordinary lead screws and independent guide components, requiring multiple sets of brackets to fix the drive and guide components separately, resulting in a complex overall structure and redundant parts. This not only increases manufacturing costs, but also requires precise calibration of multiple sets of holes during assembly, leading to low assembly efficiency. Furthermore, some mechanisms have unreasonable guide structure designs, which can easily cause jamming and wobbling during lifting, resulting in insufficient windshield lifting stability and affecting the riding experience.

[0004] Therefore, to meet the adaptation needs of motorcycle windshield lifting scenarios, there is an urgent need for a linear output mechanism that is simple in structure, has excellent guiding effect, stable and reliable output, and is easy to assemble, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a screw-type linear output mechanism.

[0006] The technical solution adopted by this utility model is: a screw-type linear output mechanism, including a worm gear reducer motor, a guide frame, a screw block, an output rod, and a mounting casting; The worm gear reducer motor has two through holes on one end of its housing. One end of the guide frame is provided with a screw hole corresponding to the through hole, and the guide frame is provided with a long groove for the screw of the worm gear reducer motor to pass through. The two side walls of the long groove are provided with guide grooves. The screw block is connected to the screw thread of the worm gear reducer motor. The screw block is clearance-fitted with the long slot and can slide along the long slot under the drive of the worm gear reducer motor. The screw block is provided with a connecting through hole. The output rod passes through the guide slot and the connecting through hole; The mounting casting includes an integrally formed collar, an extension plate at one end of the collar, an upper connecting plate above the extension plate, a vertical plate below the extension plate, and a fixed base plate below the vertical plate. The collar is assembled with the worm gear reducer motor. The upper connecting plate and the vertical plate are provided with connecting through holes corresponding to the through holes. The fixed base plate is provided with mounting holes.

[0007] Furthermore, the fixed base plate and the vertical plate are inclined.

[0008] Furthermore, the upper end of the guide frame and the end away from the worm gear reducer motor are provided with openings.

[0009] Furthermore, the fitting clearance between the screw block and the long slot is 0.05-0.15mm.

[0010] Furthermore, the difference between the inner diameter of the collar of the mounting casting and the diameter of the worm gear reducer motor housing is 0.01-0.05 mm.

[0011] The beneficial effects of this utility model are: 1. Precise guidance and stable output, suitable for motorcycle windshield requirements: The guide frame has a long slot and guide slots on both sides. The screw block fits into the long slot with a clearance, and the output rod passes through the connecting hole between the guide slot and the screw block, forming a double guiding constraint. This structure can effectively limit the radial wobble of the screw block and the output rod, avoiding jamming and offset problems during windshield raising and lowering, ensuring smooth and stable windshield raising and lowering, and improving riding comfort and adjustment reliability.

[0012] 2. Simplified structure and efficient assembly, reducing costs and assembly difficulty: The worm gear reducer motor housing has a through-hole, the guide frame has corresponding screw holes, and the upper connecting plate and vertical plate for mounting the castings have corresponding connecting through holes. All three can be fixed with just two bolts. Compared to traditional mechanisms that require multiple sets of brackets to separately fix the drive and guide components, this structure reduces the number of parts, simplifies the assembly process, eliminates the need for complex hole alignment, significantly improves assembly efficiency, and simultaneously reduces manufacturing costs and subsequent maintenance difficulty.

[0013] 3. Strong installation adaptability, suitable for motorcycle assembly scenarios: The mounting casting adopts an integrated structure of collar, extension plate, upper connecting plate, vertical plate, and fixed base plate. The collar can be stably fitted with the worm gear reducer motor, and the mounting holes of the fixed base plate facilitate quick docking with the motorcycle body structure. The overall structure is compact, with fewer parts and a small footprint, and can flexibly adapt to the windshield mounting layout of different motorcycle models, improving the mechanism's scenario adaptability.

[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] 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.

[0020] This utility model provides a screw-type linear output mechanism.

[0021] In this embodiment, refer to Figure 1-2 The screw-type linear output mechanism includes a worm gear reducer motor 1, a guide frame 2, a screw block 3, an output rod 4, and a mounting casting 5; Two through holes 6 are provided on one end of the housing of the worm gear reducer motor 1; One end of the guide frame is provided with a screw hole 7 corresponding to the through hole 6. The guide frame is provided with a long groove 8 for the screw of the worm gear reducer motor to pass through. The two side walls of the long groove 8 are provided with guide grooves 9. The screw block is threadedly connected to the screw of the worm gear reducer motor. The screw block is clearance-fitted with the long slot and can slide along the long slot under the drive of the worm gear reducer motor. The screw block is provided with a connecting through hole 10. The output rod passes through the guide slot and the connecting through hole; The mounting casting includes an integrally formed collar 11, an extension plate 12 on one end of the collar 11, an upper connecting plate 13 above the extension plate 12, a vertical plate 14 below the extension plate 12, and a fixed base plate 15 below the vertical plate 14. The collar is assembled with the worm gear reducer motor. The upper connecting plate and the vertical plate are provided with connecting through holes 16 corresponding to the through holes. The fixed base plate is provided with mounting holes 17.

[0022] In the above technical solution, a worm gear reducer motor is used as the power source. The screw and the screw block form a threaded pair transmission, which converts the rotational motion of the motor into the linear motion of the screw block. The guide frame long slot forms a radial constraint on the screw block. The guide long slots on both sides cooperate with the output rod that passes through, further limiting the sway of the screw block and the output rod, and realizing dual guidance. The mounting casting is fitted onto the motor housing through a collar, and then two bolts are used to pass through the through hole of the motor housing and the mounting casting connection through hole and cooperate with the screw hole of the guide frame to complete the integrated fixation of the three. The fixing base plate realizes the assembly of the whole with the external components through the mounting holes.

[0023] The threaded drive, combined with dual guides, ensures precise and stable linear movement of the output rod, preventing windshield lifting and lowering from getting stuck. The three components are fixed together by two bolts, simplifying the structure and assembly process and reducing costs. The integrated casting design enhances assembly stability and is suitable for motorcycle installation scenarios.

[0024] The screw of the worm gear reducer motor can be either a built-in screw or an external screw coaxially fixed to the output shaft of the worm gear reducer motor. Specifically, the fixed base plate and the vertical plate are set at an angle.

[0025] In this embodiment, the fixed base plate and the vertical plate adopt an inclined structure, so that the fixed end face (fixed base plate) of the mounting casting forms an angle difference with the motor mounting direction, which is adapted to the inclined layout of the motorcycle body windshield mounting area.

[0026] Specifically, the included angle between the fixed base plate and the vertical plate is 135-145°.

[0027] In this embodiment, the angle between the fixed base plate and the vertical plate is 135-145°. This angle matches the tilt angle design of the windshield mounting area of ​​mainstream motorcycles, so that the movement direction of the output rod after the mechanism is installed is precisely matched with the windshield lifting trajectory.

[0028] Specifically, the upper end of the guide frame and the end away from the worm gear reducer motor are open.

[0029] In this embodiment, the upper end of the guide frame and the end away from the motor are open, which facilitates the assembly and disassembly of internal components such as the screw block and output rod, while avoiding structural interference with the maximum sliding stroke of the screw block.

[0030] Specifically, the fit clearance between the screw block and the long slot is 0.05-0.15mm.

[0031] In this embodiment, the fit clearance between the screw block and the long slot is controlled at 0.05-0.15mm to ensure the amount of movement required for the screw block to slide, while avoiding radial wobble caused by excessive clearance, thus achieving a balance between "smooth sliding" and "precise guidance".

[0032] Specifically, the difference between the inner diameter of the collar of the mounting casting and the diameter of the worm gear reducer motor housing is 0.01-0.05 mm.

[0033] In this embodiment, the difference between the inner diameter of the collar and the diameter of the motor housing is set to 0.01-0.05mm to form a transition fit, which facilitates the assembly of the collar and the motor housing and ensures the coaxiality and connection stability of the two.

[0034] 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.
