Description

Technical Field

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

[0002] During motorcycle riding, the windshield effectively blocks airflow, dust, and debris, improving riding comfort and safety. However, most existing motorcycle windshields are fixed structures with no height adjustment, making it difficult to adapt to different riding speeds, road conditions, and rider heights. A fixed, low windshield is insufficient for high-speed riding, while a fixed, high windshield obstructs vision and reduces maneuverability at low speeds or when stationary.

[0003] Some adjustable windshields require manual adjustment, necessitating the rider to stop and operate manually, which is cumbersome and cannot adapt to the riding status in real time. Although there are a few electric adjustable windshield devices, they often suffer from complex structures, poor transmission stability, and weak installation adaptability, making it difficult to balance adjustment accuracy and reliability. There is an urgent need for a simple, stable electric windshield lifting device to solve these shortcomings. Utility Model Content

[0017] 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.

[0018] 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.

[0019] This utility model provides a motorcycle windshield lifting device.

[0020] In this embodiment, refer to Figure 1-2 The motorcycle windshield lifting device includes: Mounting bracket 1, the bottom of mounting bracket 1 is provided with motor bracket 2, motor bracket 2 is fixed on motor bracket 2, the output end of motor bracket 3 is connected to gearbox 4, and gearbox 4 is driven by output screw 5; Glass bracket 6, with windshield glass 7 fixed on its upper side; The main rotating arm 8 is rotatably connected at one end to the glass bracket and at the other end to the drive shaft 9, which is rotatably connected to the mounting bracket. A secondary rotating arm 10, one end of which is rotatably connected to the glass bracket, and the other end of which is rotatably connected to the mounting bracket; The connecting arm includes a left connecting arm 11, a right connecting arm 12, and a connecting shaft 13. One end of the left and right connecting arms is connected to the drive shaft, and the other end is connected to the connecting shaft. One end of the output screw is rotatably connected to the connecting shaft.

[0021] In this embodiment, a power source is formed by integrating a drive motor, gearbox, and output screw through a mounting bracket. The drive motor drives the output screw to extend and retract forward and backward via the gearbox. The output screw drives the drive shaft to rotate via a connecting shaft and connecting arm. The drive shaft drives the main rotating arm to swing, and with the auxiliary support of the secondary rotating arm, together they drive the glass bracket and windshield to achieve stable raising and lowering. The main and secondary rotating arms form a double-support structure, and the connecting arms adopt a symmetrical design to ensure balanced force transmission. This enables electric drive of the windshield, eliminating the need for manual operation and allowing for real-time height adjustment. The double rotating arm support and symmetrical connecting arm design balance the forces during the raising and lowering process, preventing glass swaying or jamming and improving transmission stability. The overall structure is modularly assembled through the bracket and rotating shaft, making it compact and easy to integrate into a motorcycle.

[0022] Specifically: the mounting bracket extends to one side of the bottom with a support foot 14, the support foot 14 is provided with a mounting part 15, and the mounting part 15 is provided with a mounting hole 16.

[0023] In this embodiment, the support foot extending from the bottom of the mounting bracket can be fixed to the corresponding position on the motorcycle body (e.g., by bolt connection) through the mounting hole of the mounting part. The extended structure of the support foot increases the mounting contact area and distributes the weight of the device and the vibration load during operation.

[0024] Specifically: a square through hole 17 is provided at one end of the left connecting arm and the right connecting arm, the cross section of the drive shaft is a square structure adapted to the square through hole, and a fixing screw hole 18 is provided on the side wall of the square through hole.

[0025] In this embodiment, the left and right connecting arms are connected to the drive shaft with a square cross-section through square through holes. The non-circular characteristics of the square structure limit the relative rotation between the connecting arms and the drive shaft. The bolts in the fixing screw holes are then used to further tighten the connection and ensure the fixed connection between the two.

[0026] Specifically: The glass bracket is provided with an installation platform 19 on its upper side, and the installation platform 19 is provided with a waist-shaped installation hole 20.

[0027] In this embodiment, the mounting platform on the upper side of the glass bracket is connected to the windshield through a waist-shaped mounting hole. The waist-shaped hole allows the windshield to be slightly adjusted in position along the length of the hole during installation to compensate for assembly errors or glass size tolerances.

[0028] Specifically, the left connecting arm and the right connecting arm are fixed together by bolts.

[0029] In this embodiment, the left and right connecting arms are fixed together by bolts to form an integral rigid structure, ensuring that the two move synchronously when subjected to force, and avoiding force transmission imbalance caused by relative displacement.

[0030] 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.
