[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Figures 1 to 6 An electric scooter shown includes a wheel 9, a body 1, a fender and a battery pack 2. The number of wheels 9 is single, and the wheel 9 is a hub motor. The middle part of the body has an opening for accommodating the wheel 9, and the wheel 9 is installed in the middle part of the body through the opening. The forward direction of the wheel 9 is parallel to the length direction of the pedal platform on the body 1. When the center of gravity of the body 1 tilts, the wheel 9 drives the body 1 to move in the direction of the tilt of the center of gravity. The fender is installed on the body 1 and covers the top of the wheel 9. The fender has an internal chamber, and the battery pack 2 is arranged in the internal chamber of the fender. The battery pack 2 is used to provide power for the electric scooter; the fender is arched, and the fender is fixedly mounted on the body 1 through its two ends. The fender is assembled from an upper shell 4 and a lower shell 5, and the battery pack 2 is divided into an upper and lower layer.

[0027] The upper shell 4 and the lower shell 5 are assembled by screw fixation. The first layer of battery pack (lower layer battery pack) is installed on the lower shell 5. In order to further improve the vehicle's endurance, the second layer of battery pack (upper layer battery pack) is installed on the first layer of battery pack. The length of the second layer of battery pack is less than that of the first layer of battery pack, and the second layer of battery pack is located in the middle of the first layer of battery pack. In order to match the installation of two layers of battery packs 2, the upper shell 4 has a bulge (bulge) in the middle. Each battery pack 2 is connected and installed by multiple batteries 21 through a battery bracket 22. A protective plate 3 is also installed on the lower shell 5, and the protective plate 3 is electrically connected to the battery pack 2. Since the battery pack 2 has a large self-weight, in order to enhance the overall strength of the fender, the following structure is adopted:

[0028] 1. The corners of the upper shell 4 are all transitioned by edges and corners 6.

[0029] 2. The bottom of the lower shell 5 is processed with evenly distributed reinforcing ribs 7.

[0030] In order to prevent foreign objects from splashing onto the user's legs during riding, the lower shell 5 has skirt edges 8 extending downward for a distance on both sides. Figure 4 The waist design shown is narrow in the middle and wide on both sides, and the skirt edge 8 blocks splashes.

[0031] In order to improve the passability of the scooter, especially when going uphill and downhill, the bottom of both ends of the body 1 has an inclined portion, which is inclined from the side close to the wheel 9 to the upper side away from the wheel 9. There is an angle α between the inclined portion and the lowest position of the wheel 9, and the angle α is 20±5°, and α is preferably 20.8°.

[0032] The mudguard design of the electric scooter of the present application conforms to the state of a normal person standing with legs spread out, with the lower part wider and the upper part narrower, so as to avoid the mudguard rubbing against the user's legs during the use of the electric scooter and causing discomfort to the user.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
