Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle braking systems, and in particular to a parking limit device for the left support handle of a motorcycle. Background Technology

[0002] Currently, when parking a motorcycle, the rider needs to hold the brake lever continuously to maintain braking. This operation method can easily lead to hand fatigue when parking for a long time, and also restricts the rider's freedom to perform other operations.

[0003] While some parking brake limiters exist on the market, such as "snap-on" or "ratchet-on" structures, these solutions typically require significant modifications to the original brake lever or mount. This not only makes installation complex but also results in poor compatibility, making it difficult to adapt to different motorcycle models. Furthermore, some existing designs are not convenient to operate when unlocking, affecting the actual user experience. Therefore, existing parking brake limiters fail to meet users' needs for convenient parking, and there is an urgent need for a simple, easy-to-install, and highly versatile solution that can reliably lock and quickly release the brake lever without significant modifications to the original vehicle structure. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, this utility model provides a motorcycle left support handle parking limit device that is highly compatible and easy to operate.

[0005] The technical implementation scheme of this utility model is as follows: a parking limit device for the left support handle of a motorcycle, comprising: a mounting base fixedly connected to the motorcycle support; a rotating shaft fixedly connected to the mounting base; a locking block rotatably connected to the rotating shaft for limiting the motorcycle support and the brake handle so that the brake handle is kept in the parking brake position; and a torsion spring fitted on the rotating shaft, one end of which is fixed to the rotating shaft and the other end of which is fixed to the locking block.

[0006] More preferably, the device further includes: a fixed base fixedly connected to the locking block; an adjusting plate slidably connected to the fixed base, which moves along the fixed base to change the overall width of the locking block, the surface of the adjusting plate having a row of equally spaced slots; a mounting bracket fixedly connected to the fixed base; a control screw threadedly connected to the mounting bracket; a pressure plate slidably connected to the mounting bracket, the end of the control screw being rotatably connected to the pressure plate; a locking plate slidably connected to the mounting bracket, used to cooperate with the slots to position the adjusting plate; and a return spring fixedly connected between the pressure plate and the locking plate.

[0007] More preferably, the device further includes a roller rotatably connected to the side of the card plate that contacts the card slot.

[0008] More preferably, the device further includes a contact pad fixedly connected to the side of the card plate and the adjustment plate that contacts the brake handle.

[0009] More preferably, the device further includes an anti-slip area fixedly connected to the adjustment plate.

[0010] More preferably, the device further includes a limiting block fixedly connected to the end of the locking block.

[0011] Compared with existing technologies, this utility model has the following advantages: It enables convenient locking and unlocking of the brake lever position, with a simple and intuitive operation process that facilitates quick driver control. Furthermore, its overall structure is streamlined, requiring no significant modifications to the original motorcycle structure, resulting in stronger compatibility with existing models and better performance.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: A parking limit device for the left support handle of a motorcycle, combined with... Figures 1-4 As shown, it includes: a mounting base 3 fixedly installed on the motorcycle support 1; a rotating shaft 301 fixedly installed on the mounting base 3; a locking block 5 rotatably installed on the rotating shaft 301, used to restrict the motorcycle support 1 and the brake handle 2, so that the brake handle 2 is held in the parking brake position; and a torsion spring 4 fitted on the rotating shaft 301, one end of which is fixed to the rotating shaft 301 and the other end of which is fixed to the locking block 5.

[0021] During the parking operation, after the driver turns the brake lever 2 to complete the parking action, pressing the locking block 5 with the thumb will cause the locking block 5 to engage between the motorcycle support 1 and the brake lever 2. The torsion spring 4 will undergo torsional deformation. At this time, the brake lever 2 cannot return to its original position due to the limiting effect of the locking block 5. At the same time, the return tendency of the brake lever 2 will further tighten the locking block 5, forming a two-way locking state. In this state, the brake lever 2 can stably maintain the braking state without the driver having to continuously apply force to operate it, effectively improving driving comfort. During the unlocking operation, the driver turns the brake lever 2 again, increasing the distance between the lever and the motorcycle support 1 to exceed the width of the locking block 5. The torsion spring 4 will drive the locking block 5 to return to its original position, releasing the limiting constraint on the brake lever 2. At this time, releasing the brake lever 2 will cause it to automatically return to its original position under the action of the brake cable, completing the release of the parking state.

[0022] In summary, this device enables convenient locking and unlocking of the brake lever position 2. The operation process is simple and intuitive, allowing the driver to operate it quickly. At the same time, the overall structure of this device is streamlined, requiring no major modifications to the original structure of the motorcycle, resulting in stronger compatibility with existing models and better performance.

[0023] Combination Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the device also includes: a fixed base 6 fixedly mounted on the locking block 5; an adjusting plate 7 slidably mounted on the fixed base 6, the adjusting plate 7 changing the overall width of the locking block 5 by displacement along the fixed base 6, the adjusting plate 7 having a row of equally spaced slots 8 on its surface; a mounting bracket 9 fixedly mounted on the fixed base 6; a control screw 10 threadedly mounted on the mounting bracket 9; a pressure plate 11 slidably mounted on the mounting bracket 9, the end of the control screw 10 being rotatably mounted with the pressure plate 11; a locking plate 13 slidably mounted on the mounting bracket 9, used to cooperate with the slots 8 to achieve the positioning of the adjusting plate 7; and a return spring 12 fixedly mounted between the pressure plate 11 and the locking plate 13.

[0024] When the width of the locking block 5 needs to be adjusted via the adjusting plate 7, reverse the control screw 10 to move the pressure plate 11 and the locking plate 13 away from the adjusting plate 7, causing the locking plate 13 to separate from the slot 8 and release the locking of the adjusting plate 7. At this time, the actual width of the locking block 5 can be changed using the adjusting plate 7 according to the actual situation of the motorcycle. If not, turn the control screw 10 forward to move the pressure plate 11 closer to the adjusting plate 7. During this process, through the connection of the return spring 12, the locking block 5 first moves towards the adjusting plate 7 and locks into the corresponding slot 8 on the adjusting plate 7, thus pre-positioning the position of the adjusting plate 7. Then, the pressure plate 11 continues to move and compresses the return spring 12. Under the return trend of the return spring 12, the locking plate 13 and the slot 8 are stably engaged, thereby fixing the position of the adjusting plate 7. At this time, the width of the locking block 5 is fixed to the adjusted size.

[0025] This device uses an adjustable adjustment plate 7 to achieve precise, graded adjustment of the width of the card block 5, meeting the usage requirements of different parking gap scenarios. The adjustment process is convenient and the positioning is stable.

[0026] Combination Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the device also includes: a roller 14 rotatably mounted on the side of the clamping plate 13 that contacts the clamping slot 8, used to reduce the resistance between the clamping plate 13 and the clamping slot 8 of the adjusting plate 7, ensuring that the adjusting plate 7 can move smoothly during position adjustment and reducing mechanical wear between components; a contact pad 15 fixedly mounted on the side of the clamping plate 13 and the adjusting plate 7 that contacts the brake handle 2, which disperses the pressure applied by the brake handle 2 through its own elastic deformation, reduces local stress concentration, thereby reducing surface wear and extending the service life of the clamping plate 13, the adjusting plate 7 and the brake handle 2; an anti-slip area 16 fixedly mounted on the adjusting plate 7, which increases the friction between the hand and the adjusting plate 7 to effectively prevent slippage during operation; and a limiting block 17 fixedly mounted on the end of the clamping block 5, which forms an auxiliary cooperation relationship with the brake handle 2 when the device is in the parking state, effectively limiting the displacement range of the clamping block 5, preventing parking failure caused by accidental slippage of the clamping block 5, and further ensuring the safety and stability of the device during use.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
