[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example:

[0047] like Figure 1 , 3 , 5, as shown, is a four-wheeled scooter, comprising a skateboard 1, a pulley 2, a controller, a brake, a power supply and a driving motor 3, wherein the skateboard 1 is provided with a photoelectric switch 4, wherein the pulley 2 is connected to the lower surface of the skateboard 1, the power supply and the controller are connected to the skateboard 1, the driving motor 3 is connected to the pulley 2 and drives the pulley 2 to rotate, the driving motor 3, the power supply, the brake and the photoelectric switch 4 are all electrically connected to the controller and controlled by the controller, and the power supply is electrically connected to the photoelectric switch, the brake and the driving motor 3.

[0048] Four photoelectric switches 4 are arranged on the skateboard 1, two of which are arranged at the front end of the skateboard, and the other two are arranged at the rear end of the skateboard. When any one of the four photoelectric switches is triggered, the drive motor is powered on; when any two of the four photoelectric switches are triggered, the electric scooter brakes normally; when any three of the four photoelectric switches are triggered, the electric scooter travels at a constant speed; when all four photoelectric switches are triggered, the electric scooter accelerates evenly.

[0049] like Figure 1 and Figure 6As shown, a pulley fixing member 5 is provided on the lower surface of the slide plate, and the pulley fixing member 5 is detachably connected to the pulley 2. The pulley fixing member 5 includes a fixing plate 51, a fixing block 52 and a fastening screw 53. The fixing plate 51 is provided with a slide groove 511, and the fixing block 52 is inserted into the slide groove 511 and then fixed by the fastening screw 53. The fixing plate 51 is fixedly connected to the slide plate 1 by screws, and the pulley 2 is fixedly connected to the fixing block 52. In this way, the fixing block 52 connected with the pulley 2 is inserted into the slide groove 511 on the fixing plate 51, and then the fixing block 52 and the fixing plate 51 are fixed by the fastening screw 53 to realize the replacement of the pulley 2.

[0050] like Figure 2 As shown, the pulley fixing member 5 can also be used to replace the universal wheel 21 and the double wheels of the bridge frame, so that the conversion between the four-wheel scooter and the three-wheel scooter can be easily realized, and one vehicle can be used for multiple purposes more conveniently.

[0051] like Figure 1 , 2 As shown in Figure 3, the power source includes a rechargeable battery, and the rechargeable battery is connected to the bottom of the skateboard 1 through a battery box 6, wherein the battery box 6 is detachably connected to the skateboard 1. Preferably, the battery box 6 is connected to the skateboard 1 through bolts and nuts, and the nuts are configured as non-circular polygonal nuts with edges and corners. At the same time, the battery box 6 is provided with a countersunk hole that matches the polygonal nut, and the skateboard 1 is provided with a screw hole for the bolt to pass through. The bolt is passed through the screw hole on the skateboard 1 and the countersunk hole in the battery box 6, and then the screw is locked in the polygonal countersunk hole with the polygonal nut. At this time, a layer of sandpaper 11 can also be glued to the upper surface of the skateboard 1 with a strong glue to prevent the bolt from loosening.

[0052] like Figure 4As shown, the bridge double wheel includes a bridge and two rollers 23 connected at both ends of the bridge, the rollers 23 include a tire skin 231 and a wheel hub 232, the drive motor 3 is located inside the tire skin 231, the bridge 22 passes through the center of the drive motor 3 and is fixedly connected to the drive motor 3, and the wheel hub 232 is provided with a heat dissipation hole. The wheel hubs 232 at both ends of the tire skin and the drive motor 3 are fixedly connected by a long screw. Such a design has the advantages of convenient heat dissipation of the drive motor 3 and convenient replacement of the tire skin 231. Since the bridge 22 passes through the center of the drive motor 3, when the motor generates a lot of heat during operation, if the heat is not discharged in time, the temperature of the drive motor 3 will rise sharply, which will not only affect the service life of the drive motor, but also endanger the use of the tire skin. When the motor generates a lot of heat during operation, the heat can be dissipated outward in time through the metal bridge 22 passing through the center of the drive motor and the heat dissipation hole.
