Technical Field

[0001] This utility model relates to vehicle support technology, specifically a vehicle auxiliary double support structure. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power sources and are based on ordinary bicycles but are equipped with motors, controllers, batteries, throttles, brake levers, and other control components and display instrument systems.

[0003] The existing electric kickstands have a fixed length, which cannot adapt to the frames of different types of vehicles. This means that each frame needs to be redesigned with a corresponding kickstand length, which is costly and time-consuming. Furthermore, it requires subsequent adjustments to select different kickstand lengths. Utility Model Content

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] Example 1:

[0025] like Figure 1As shown in Figure 3, an auxiliary double support structure for a wheel 2 is provided on a frame 1. The frame 1 is rotatably connected to the wheel 2 and includes two support components, which are respectively provided on both sides of the frame 1. Each support component includes a mounting frame 4, which is fixed to the frame 1. The mounting frame 4 is provided with a drive unit, a swing unit, and a swing arm 5. The drive unit drives the swing arm 5 to rotate through the swing unit. The bottom end of the swing arm 5 is provided with a telescopic hole 11, through which a telescopic rod 6 passes. The telescopic rod 6 is provided with several through holes evenly distributed. Both sides of the bottom end of the swing arm 5 are provided with threaded holes 10, and screws are threaded into the threaded holes 10. The end of the screw extends into the through hole to fix the telescopic rod 6 to the swing arm 5.

[0026] The number of threaded holes 10 is multiple, which can improve the fixing effect between the telescopic rod 6 and the swing arm 5. The telescopic rod 6 can also be selected in different lengths to adapt to higher or lower frames 1.

[0027] The wheel 2 of this utility model uses an auxiliary double support structure, employing a telescopic rod 6 and screws to adjust the distance between the auxiliary wheel 7 and the swing arm 5, thereby adjusting the length of the entire foot support. This adapts to the frames 1 of different types of vehicles, offering good flexibility and strong adaptability. Furthermore, it uses a worm gear 12 and a worm 13 as the swing unit. Utilizing the self-locking effect of the worm gear 12 and worm 13, it can provide effective support even when the vehicle is without power. In addition, the worm gear 12 and worm 13 transmit a large torque, capable of withstanding large loads and frequent impacts. This avoids the situation where the motor of a conventional gear reduction mechanism cannot withstand large impact forces, leading to direct damage or scrapping of the motor. It is suitable for uneven roads and special conditions such as roads with speed bumps.

[0028] The mounting frame 4 is covered with a protective cover 3; the protective cover 3 is set to protect the drive unit and the swing unit, and prevent solid particles or other impurities from entering the mounting frame 4, which would cause the drive unit and the swing unit to malfunction.

[0029] The drive unit includes a motor 16, a drive gear 15, and a transmission gear 14. The motor 16 is fixed to the mounting frame 4. Both the drive gear 15 and the transmission gear 14 are rotatably connected to the mounting frame 4. The drive gear 15 meshes with the transmission gear 14 and is sleeved on the output shaft end of the motor 16. The swing unit includes a worm gear 12 and a worm 13. One end of the worm 13 is coaxially arranged with the transmission gear 14, and the other end of the worm 13 is rotatably connected to the mounting frame 4. The worm gear 12 meshes with the worm 13 and is rotatably connected to the middle of the mounting frame 4. The top end of the swing arm 5 is fixed to the worm gear 12. The motor 16 drives the drive gear 15 to rotate, which in turn drives the transmission gear 14 to rotate, thereby causing the worm 13 to rotate. Thus, the rotation of the worm gear 12 drives the swing arm 5 to swing, realizing the descent and repositioning of the telescopic rod 6 and the auxiliary wheel 7.

[0030] The bottom end of the swing arm 5 protrudes outward.

[0031] The bottom end of the telescopic rod 6 is provided with a wheel frame 8, and the wheel frame 8 is rotatably connected to an auxiliary wheel 7.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
