[0018] 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.

[0019] Example 1

[0020] like Figures 1-3As shown, the liftable safety balance wheel for two-wheeled electric vehicles and motorcycles includes an internal meshing rack 1, a mounting bracket 2, a right bracket 4, a roller 5, a drive gear 6, a drive motor 7, a left bracket 8, and a rotating shaft 9; the left bracket 8 and the right bracket 4 are respectively installed at both ends of the rotating shaft 9, and the left bracket 8 and the right bracket 4 are reinforced and connected to the rotating shaft 9 by a fixing plate 3.

[0021] The mounting bracket 2 is rotatably mounted on the rotating shaft 9 and located between the left bracket 8 and the right bracket 4; the mounting bracket 2 has multiple mounting holes for installation; the mounting bracket 2 is an L-shaped plate structure, and the short plate of the L-shape has a fixing hole for installing the drive motor 7; the long plate of the L-shape is rotatably mounted on the rotating shaft 9 through a connecting lug with a connecting hole on the back.

[0022] The drive motor 7 is fixedly mounted on the mounting bracket 2, and the internal meshing rack 1 is mounted on the rotating shaft 9 and located between the drive motor 7 and the mounting bracket 2; the toothed part of the internal meshing rack 1 has an arc-shaped structure, and the drive gear 6 that meshes with the internal meshing rack 1 is mounted on the motor shaft of the drive motor 7; the left bracket 8 and the right bracket 4 are both equipped with rollers 5 near the bottom.

[0023] Working principle:

[0024] like Figure 4 As shown, the device is installed on the rear wheel of the electric vehicle via the mounting bracket 2. When encountering slippery conditions due to rain or snow, the drive motor 7 is activated, causing the drive gear 6 to rotate. The drive gear 6 meshes with the internal meshing rack 1. Since the toothed part of the internal meshing rack 1 has an arc-shaped structure, the drive gear 6 drives the rotating shaft 9 to rotate through the internal meshing rack 1. The rotating shaft 9 then drives the left and right brackets 4 to rotate until the rollers 5 on the left and right brackets 4 are lowered onto the ground. At this point, it can be used as an auxiliary wheel for the two-wheeled vehicle, increasing the stability of the vehicle. When not in use, the drive motor 7 is reversed to retract the rollers 5.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
