Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a lifting and connecting structure for a motorcycle windshield and a motorcycle windshield using the same. Background Technology

[0002] Motorcycle touring, as a more free and nature-friendly way of traveling, is very popular in some areas. As the length of motorcycle trips increases, the probability of encountering sandstorms, mosquitoes, rain, and snow also increases. A windshield of appropriate height can significantly reduce their impact on the rider. Furthermore, when riding at high speeds, a higher windshield can significantly reduce wind resistance and pressure on the rider's neck, as well as significantly reduce wind noise and improve rider comfort. However, when riding in urban areas at low speeds, a higher windshield can affect the rider's heat dissipation needs, especially in hot seasons when people usually need to use the wind from the motorcycle to cool down. Given that people have different needs for windshield height in different usage scenarios, there is a current need for a mechanism that can connect the windshield height adjustment to the motorcycle body. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting connection structure for a motorcycle windshield and a motorcycle windshield using the same. The technical problem to be solved is how to connect the windshield to the motorcycle body in a liftable manner.

[0004] To achieve the above objectives, the solution of this utility model is as follows:

[0005] A lifting connection structure for a motorcycle windshield includes a guide rail, a first support arm, a second support arm, and an elastic element;

[0006] The guide rail is high at one end and low at the other end. There are two rails, which are parallel to each other, and are used to install on the motorcycle body.

[0007] The first arm and the second arm are pivotally connected at the middle to form an X-shaped scissor mechanism. The scissor mechanism is used for the installation and connection of the motorcycle windshield. The two ends of the first arm and the second arm are respectively provided with mating parts, which are used to fit with the guide rail.

[0008] The elastic element connects between the first arm and the second arm. Through elasticity, the first arm and the second arm pivot relative to each other, so that the scissor mechanism is kept spread out between the two guide rails and is tightly fitted to the inside of the two guide rails through the mating part, or the scissor mechanism is kept contracted and close to the two guide rails through the mating part and clamped to the outside of the two guide rails, so that the scissor mechanism is fitted on the guide rails and slides along the guide rails.

[0009] Furthermore, the two guide rails are a left guide rail and a right guide rail, which are spaced apart. The mating part at the left end of the first arm abuts against the right side of the left guide rail, and the mating part at the right end of the first arm abuts against the left side of the right guide rail. The mating part at the left end of the second arm abuts against the right side of the left guide rail, and the mating part at the right end of the second arm abuts against the left side of the right guide rail.

[0010] Furthermore, the mating part is a roller for rolling on the guide rail.

[0011] Furthermore, the roller is made of rubber.

[0012] Furthermore, a guide groove is formed on the guide rail for the mating part to be embedded in, and the mating part is confined within the guide groove.

[0013] Furthermore, the elastic element is a spring.

[0014] A motorcycle windshield, employing the lifting connection structure of a motorcycle windshield as described above, for mounting the motorcycle windshield on the motorcycle body, and further comprising a drive mechanism for driving a scissor fork mechanism to move along two guide rails, thereby causing the motorcycle windshield to rise and fall on the motorcycle body.

[0015] Furthermore, the driving mechanism includes a rack, a gear, and a drive motor. The rack extends parallel to the guide rail and is connected to the scissor lift mechanism for synchronous movement. The drive motor is fixed relative to the guide rail. The gear rotates under the drive of the drive motor and meshes with the rack. The rotation of the drive motor then drives the scissor lift mechanism to move along the guide rail.

[0016] Furthermore, a worm gear self-locking structure is provided between the drive motor and the gear.

[0017] Furthermore, the rack is pivotally connected to the scissor mechanism, and the pivotally connected shaft is coaxial with the pivotally connected shafts of the first and second arms. A stop bar is also provided, which is fixedly set relative to the guide rail, parallel to the guide rail, and abuts against the back side of the rack.

[0018] Furthermore, a control button is provided, which is electrically connected to the drive motor and is located on the motorcycle handlebars. The control button is used to control the drive motor to rotate forward or backward, so that the scissor mechanism can drive the motorcycle windshield to rise or fall.

[0019] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0020] (1) One end of the guide rail is high and the other end is low. There are two guide rails, which are parallel to each other and are used to install on the motorcycle body. The first arm and the second arm are pivotally connected in the middle to form an X-shaped scissor mechanism. The scissor mechanism is used for the installation of the motorcycle windshield. The first arm and the second arm are respectively provided with mating parts at both ends. The mating parts are used to fit with the guide rails. The elastic element is connected between the first arm and the second arm. The elastic element drives the first arm and the second arm to pivot relative to each other so that the scissor mechanism is kept open between the two guide rails and is tightly fitted to the inside of the two guide rails through the mating parts. Alternatively, the scissor mechanism is kept to retract towards the two guide rails and is clamped to the outside of the two guide rails through the mating parts. Thus, the scissor mechanism fits on the guide rails and slides along the guide rails, thereby realizing the lifting and lowering connection of the motorcycle windshield to the motorcycle body.

[0021] (2) Even if the connecting structure is used for a long time and the guide rail and mating parts are worn, the elastic element can drive the first arm and the second arm to pivot to compensate for the wear.

[0022] (3) When the mating part is a roller, the large-sized roller can be made without lubricating grease, thereby fundamentally eliminating the problems of grease aging and easy dust contamination caused by grease lubrication in traditional guide rail structures. Attached Figure Description

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0030] A lifting and connecting structure for a motorcycle windshield, such as Figure 1-4 As shown, the device includes a guide rail 1, a first support arm 2, a second support arm 3, and an elastic element 4. One end of the guide rail 1 is higher than the other, creating a height difference. Two guide rails 1 are provided, parallel to each other, for mounting on the motorcycle body. Specifically, in this embodiment, both guide rails 1 extend longitudinally, with the two guide rails spaced apart laterally, but this is not a limitation. The first support arm 2 and the second support arm 3 are pivotally connected at the middle, forming an X-shaped scissor mechanism 5. The scissor mechanism 5 is used for mounting the motorcycle windshield. The mounting method is not specifically limited, as long as the windshield can rise and fall along the guide rail 1 with the scissor mechanism 5. Specific embodiments are given later. The first support arm 2 and the second support arm 3 are respectively provided with mating parts at both ends, which are used to engage with the guide rail 1. It can be a sliding fit or a rolling fit, and a preferred embodiment will be given later; the elastic element 4 is connected between the first arm 2 and the second arm 3, and the elastic element drives the first arm 2 and the second arm 3 to pivot relative to each other, so that the scissor mechanism 5 is kept spread out between the two guide rails 1, and is tightly fitted to the inner side of the two guide rails 1 by the mating part (the opposite side of the two guide rails 1 is the inner side), or the scissor mechanism 5 is kept contracted and close to the two guide rails 1 by the mating part, and is clamped to the outer side of the two guide rails 1 by the mating part (the opposite side of the two guide rails 1 is the outer side), so that the scissor mechanism 5 is fitted on the guide rails 1 and slides along the guide rails 1, so that the windshield can be raised and lowered and installed on the motorcycle body. Of course, the windshield is specifically installed in front of the driver's seat at the front of the motorcycle.

[0031] Specifically, in this embodiment, the two guide rails 1 are a left guide rail 15 and a right guide rail 16, which extend longitudinally and are spaced apart on the left and right. The first guide rail 15 is on the left and the second guide rail 16 is on the right. The mating part at the left end of the first support arm 2 abuts against the right side of the left guide rail 15, and the mating part at the right end of the first support arm 2 abuts against the left side of the right guide rail 16. The mating part at the left end of the second support arm 3 abuts against the right side of the left guide rail 15, and the mating part at the right end of the second support arm 3 abuts against the left side of the right guide rail 16. The mating part is a roller 7, which is rotatably mounted on the first support arm 2 and the second support arm 3 for rolling on the guide rail 1. A guide groove 8 is formed on the guide rail 1 for the roller 7 to be embedded in. The roller 7 is confined in the guide groove 8 and rolls along the guide groove 8, which can prevent it from falling out and has higher stability. More preferably, the roller 7 is made of rubber to buffer vibration.

[0032] Specifically, in this embodiment, the elastic element 4 is a tension spring, and two springs are provided. From the left and right sides of the pivot point of the first arm 2 and the second arm 3, the first arm 2 and the second arm 3 are pulled closer to each other in the longitudinal direction and opened outward in the transverse direction.

[0033] A motorcycle windshield utilizes the aforementioned lifting connection structure to mount the windshield onto the motorcycle body. It also includes a drive mechanism that drives a scissor mechanism 5 to move along two guide rails 1, thereby raising and lowering the windshield on the motorcycle body. The drive mechanism can be any existing linear drive mechanism, without specific limitations. Specifically, in this embodiment, the drive mechanism includes a rack 9, a gear 10, and a drive motor 11. The rack 9 extends parallel to the guide rails 1 and is connected to the scissor mechanism 5 for synchronous movement. The drive motor 11 is fixed relative to the guide rails 1, and the gear 10 is fixed in position relative to the guide rails, rotating under the drive of the drive motor 11. The gear 10 meshes with the rack 9, thereby driving the scissor mechanism 5 to move along the guide rails 1 through the rotation of the drive motor 11, achieving electrically driven raising and lowering of the windshield.

[0034] Preferably, in this embodiment, in order to ensure that the windshield can be fixed at any height while simplifying the structure as much as possible, a worm gear self-locking structure is provided between the drive motor 11 and the gear 10, so that the weight of the windshield will not cause the drive motor 11 to rotate, thus achieving self-locking.

[0035] More specifically in this embodiment, the rack 9 is pivotally connected to the scissor mechanism 5. The pivotally connected shaft is coaxial with the pivotally connected shafts of the first arm 2 and the second arm 3. A stop bar 12 is also provided, which is fixedly disposed relative to the guide rail 1 and parallel to the guide rail 1. The stop bar 12 abuts against the back side of the rack 9, keeping the rack 9 in contact with the stop bar 12, thus restricting the rotation of the rack 9 and ensuring the effectiveness of the transmission structure. Preferably, a bracket 14 is also provided, which is fixed to the rack 12 and is used to install and fix the windshield.

[0036] Specifically, in this embodiment, a control button is also provided. The control button is electrically connected to the drive motor 11 and is located on the motorcycle handlebars. It is used to control the drive motor 11 to rotate forward or reverse so that the scissor mechanism 5 can drive the motorcycle windshield to rise or fall.

[0037] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
