[0033] like Figures 1 to 5 As shown, a skating and anti-falling device for a two-wheeled electric vehicle comprises a sled 1 and two auxiliary side wheels 6 installed below the sled 1, wherein the sled 1 comprises two wheel body brackets 3 arranged in parallel and a sled bracket 4 fixedly installed below the two wheel body brackets 3, an inverted U-shaped roller support 5 is arranged at one end below the wheel body bracket 3 away from the sled bracket 4, and the auxiliary side wheels 6 are rotatably installed in the open end of the inverted U-shaped roller support 5; the skating and anti-falling device for the two-wheeled electric vehicle can be installed to the bottom of the pedal position of the two-wheeled electric vehicle via the sled bracket 4, and specifically, the skating and anti-falling device for the two-wheeled electric vehicle can be fixed to the bottom of the pedal position of the two-wheeled electric vehicle by bolt connection;

[0034] The width of the sled bracket 4 is not greater than 600 mm; the distance between the outer ends of the two handlebars of the existing two-wheeled electric vehicle is generally greater than 700 mm. Therefore, in order to ensure that the skating and anti-falling device for the two-wheeled electric vehicle does not interfere with other running electric vehicles during use and to ensure that it occupies a small space, the width of its supporting component, that is, the sled bracket 4, is set to be smaller than the distance between the outer ends of the two handlebars of the existing two-wheeled electric vehicle;

[0035] See also Figure 2 The wheel support 3 includes two steel plates 31 arranged in parallel, and the two steel plates 31 are fixed to the sled support 4 by bolt connection and / or welding connection;

[0036] See also Figure 3 , both ends of the closed end of the inverted U-shaped roller support 5 are fixedly installed with mounting support plates 51, and the mounting support plates 51 are fixed to the steel plate 31 by bolt connection;

[0037] The mounting support plate 51 is fixed to the steel plate 31 by bolt connection, so that the inverted U-shaped roller support 5 can be easily removed from the wheel body bracket 3, which is convenient for maintenance;

[0038] See also Figures 4 to 5 The sled support 4 includes two sled slide seats 41 arranged in parallel and a second steel plate 42 fixedly mounted on the left and right ends of the top of the sled slide seat 41, and two wheel support brackets 3 are respectively fixedly mounted on the front end and the rear end of the top of the second steel plate 42;

[0039] The sled slide 41 includes a bottom sliding steel plate 43 and a bearing steel plate 44 arranged parallel to and above the bottom sliding steel plate 43 , and connecting steel plates 45 are evenly distributed between the bottom sliding steel plate 43 and the bearing steel plate 44 ;

[0040] Both ends of the connecting steel plate 45 are fixed to the bottom sliding steel plate 43 and the bearing steel plate 44 respectively by bolt connection and / or welding connection; a plurality of connecting steel plates 45 are provided to connect the bottom sliding steel plate 43 and the bearing steel plate 44, thereby enhancing the connection strength between the bottom sliding steel plate 43 and the bearing steel plate 44 and ensuring the stability of the sled slide 41 during sliding;

[0041] The left end of the bottom sliding steel plate 43 is fixedly mounted with an arc-shaped buffer steel plate 46, which is used to reduce the friction between the bottom sliding steel plate 43 and the snow, increase the lateral stability, and protect the sled slide seat 41;

[0042] A sliding pad is fixedly installed at the bottom of the bottom sliding steel plate 43; wherein, the distance between the bottom of the sliding pad and the ground is 5-10mm, so that the skating and anti-falling device for the two-wheeled electric vehicle is suitable for sliding on the snow, and the sliding pad is made of a material with good wear resistance and impact resistance, specifically, it can be made of polymer polyethylene board, metal, wood or other lightweight and strong materials, thereby ensuring the stability and safety of the skating and anti-falling device for the two-wheeled electric vehicle when operating on the snow.

[0043] In actual use, since the distance between the bottom of the sliding pad and the ground is 5-10mm, there are two situations when riding: when there is snow on the road and when there is no snow on the road. The use of the ice skating and anti-falling device for the two-wheeled electric vehicle is analyzed in two situations: when there is snow on the road and when there is no snow on the road. The analysis is as follows:

[0044] Situation 1: When there is snow on the road, the ruts made by the sled 1 in front can be easily passed by the auxiliary side wheels 6 at the back, so that skiing can be achieved;

[0045] Case 2: On an icy surface with no snow on the road, the side wheel stand and sled can be installed to use it as an electric sled, using the power of the electric vehicle for skating.

[0046] In addition, during actual use, the two sled slides 41 arranged in parallel can be removed from the steel plate 42. At this time, the steel plate 42 and the wheel body bracket 3 form a firm rectangular frame, which is installed at the bottom of the pedal of the two-wheeled electric vehicle. The installation method of the auxiliary side wheel 6 remains unchanged. The use of the ice skating and anti-falling device for the two-wheeled electric vehicle is analyzed, which is divided into two situations: the road surface has no snow and the season is other than winter. The analysis is as follows:

[0047] Case a: For an icy road with no snow on it, the two auxiliary side wheels 6 under the rectangular frame can prevent the two-wheeled electric vehicle from sliding;

[0048] Case b: In seasons other than winter, when the two-wheeled electric vehicle needs to carry heavy objects, the two auxiliary side wheels 6 can prevent the two-wheeled electric vehicle from slipping;

[0049] Finally, in actual use, the sled 1 can be removed from the two-wheeled electric vehicle to restore the two-wheeled electric vehicle to a normal riding state;

[0050] The utility model provides an ice skating and anti-falling device for a two-wheeled electric vehicle. A detachable sliding support device is added under the electric vehicle to support the electric vehicle. The utility model is suitable for using the electric vehicle on icy roads in rainy and snowy weather, and reduces the safety hazard of riding the electric vehicle on icy roads in rainy and snowy weather.
