Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, and particularly relates to a motorcycle windshield lifting device. Background Art

[0002] During the driving of a motorcycle, as a key component, the windshield can effectively reduce wind resistance, reduce wind noise and wind impact on the rider, and provide a comfortable riding environment. At the same time, the windshield can also resist external factors such as wind, rain, and flying insects to a certain extent, ensuring riding safety.

[0003] Currently, most motorcycle windshields on the market are set at a fixed height. Such a fixed windshield cannot be flexibly adjusted according to the actual needs of riders, such as different heights, riding speeds, weather conditions, etc. When the rider is tall, the fixed-height windshield is difficult to effectively block the airflow, resulting in the rider still bearing a large wind resistance; when driving at high speed, the insufficient height of the windshield cannot fully play the role of reducing wind noise. In addition, when the weather changes, such as in bad environments like heavy rain and sandstorms, the fixed windshield cannot be raised to enhance the protection effect. Therefore, the research and development of a lifting device that can flexibly adjust the height of the windshield is of great significance for improving the performance and riding experience of motorcycles.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] The present invention provides a windshield lifting device for a motorcycle.

[0025] In this embodiment, referring to Figures 1-4 , this windshield lifting device for a motorcycle includes a mounting bracket 1 for fixing to the motorcycle and a windshield bracket 2 for mounting the windshield glass 19, and further includes a screw drive assembly for driving the windshield bracket to lift and lower. The screw drive assembly includes a driving shaft 3, a driving crank arm 4, a screw 5, a screw motor 6, a driven shaft 7, a screw block 8, a driving swing arm 9, and a driven swing arm 10;

[0026] The output end of the screw motor is connected to the screw 5. One end of the screw 5 away from the screw motor is threadedly connected to the screw hole of the screw block 8. The screw block 8 is rotatably connected to one end of the driving crank arm. The other end of the driving crank arm 4 is connected to the driving shaft 3. Both ends of the driving shaft pass through the mounting bracket and are fixedly connected to the driving swing arm 9. One end of the driving swing arm 9 away from the driving shaft is rotatably connected to the driving connecting arm 11 on the windshield bracket;

[0027] The driven shaft 7 is fixedly connected to the housing of the screw motor 6. Both ends of the driven shaft pass through the housing of the mounting bracket and are fixedly connected to one end of the driven swing arm. One end of the driven swing arm away from the driven shaft is rotatably connected to the windshield bracket.

[0028] In the above technical solution, after the screw motor starts, it outputs power and drives the screw to rotate. Since the screw and the screw block are threadedly connected, the rotation of the screw is converted into the linear movement of the screw block along the screw. When the screw block moves, it drives the driving crank arm to drive the driving shaft to rotate. The driving shaft is fixedly connected to the driving swing arm, and the driving swing arm then pulls the driving connecting arm on the glass bracket to realize the lifting of the glass bracket. At the same time, the driven shaft is fixedly connected to the outer shell of the screw motor. When the screw motor is running, the driven shaft moves with the motor shell and drives the glass bracket through the driven swing arm, cooperating with the driving swing arm to ensure the stability of the lifting of the glass bracket. Through the transmission of the screw drive assembly, the stable and flexible lifting of the glass bracket is realized, and the windshield height can be accurately adjusted according to different riding scenarios and the needs of riders, effectively reducing wind resistance and wind noise, and improving riding comfort and safety. Moreover, the entire transmission system has a compact structure, and all components cooperate with each other to ensure the reliability and stability of the operation of the device.

[0029] Specifically, the glass bracket extends installation blocks 12 towards the four corners, and installation holes 13 for installing the windshield glass are provided on the installation blocks 12.

[0030] In this embodiment, the glass bracket extends installation blocks towards the four corners, and installation holes are provided on the installation blocks. Through connecting parts such as bolts and nuts, the windshield glass is fixed in the installation holes to realize the stable connection between the windshield glass and the glass bracket.

[0031] Specifically, the driving shaft is rotationally matched with the installation bracket through a bearing 14.

[0032] In this embodiment, the driving shaft is rotationally matched with the installation bracket through a bearing. The bearing plays a role in supporting and reducing friction, enabling the driving shaft to rotate smoothly within the installation bracket. When the driving crank arm drives the driving shaft to rotate, the driving shaft can freely rotate around the center of the bearing.

[0033] Specifically, the cross-section of the driving shaft is a polygonal structure, and a polygonal through-hole 15 adapted to the driving shaft is provided on the driving crank arm.

[0034] In this embodiment, the cross-section of the driving shaft is a polygonal structure (such as a square or a rectangle), and a polygonal through-hole adapted thereto is provided on the driving crank arm. When the driving shaft is inserted into the polygonal through-hole of the driving crank arm, the two form a tight fit. When the driving shaft rotates, the torque can be transmitted to the driving crank arm without slipping through this non-circular cross-section fit.

[0035] Specifically, the driving crank arm includes a left crank arm 16 and a right crank arm 17. A clearance groove 18 for connecting with the screw block is formed between the left crank arm 16 and the right crank arm 17. One end of the screw block extends into the clearance groove and is rotationally connected to the driving crank arm through a pin shaft.

[0036] In this embodiment, the driving crank arm is composed of a left crank arm and a right crank arm, and a clearance groove is formed between the two. One end of the screw block extends into the clearance groove, and a rotational connection with the driving crank arm is achieved through a pin shaft. When the screw block moves linearly along the screw rod, it can swing in the clearance groove, thereby driving the driving crank arm to rotate around the driving shaft.

[0037] Dear technicians, please note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the protection scope of this patent right.
