A lithium battery pack, a motor, and a motor controller are installed at the top center of the subframe. The lithium battery pack is connected to the motor and the motor controller by wires to supply power. The motor controller is connected to the electric vehicle shifter and the motor by cables to control the motor's operating status. The motor is connected to the drive wheel through a transmission mechanism.

[0011] Preferably, an auxiliary support wheel is installed on each of the rear sides of the main frame, and the auxiliary support wheel supports the rear of the track.

[0012] Preferably, the top of the subframe is also equipped with multiple anti-slip strips for the foot pedals. The anti-slip strips have a U-shaped cross-section and the top of the anti-slip strips are provided with a number of isosceles trapezoidal anti-slip teeth.

[0013] Preferably, a trailer ring is also installed at the rear top of the subframe.

[0014] The transmission mechanism includes a driving gear mounted on the motor drive shaft, a driven gear mounted on the drive wheel shaft, and a transmission chain, wherein the transmission chain meshes with the driving gear and the driven gear.

[0015] Preferably, a protective cover for the transmission mechanism is installed on the side of the main frame, covering the transmission mechanism. The beneficial effects of this invention are: guide wheels and drive wheels are installed at both ends of the main frame, and tracks are installed on the guide wheels and drive wheels; a lithium battery pack and a motor are installed at the top center of the sub-frame mounted on the main frame. The motor drives the drive wheels to rotate through the transmission mechanism, thereby allowing the tracks to move on the ground; the electric tracked scooter uses tracks as the walking part in contact with the ground, simplifying the structure of the walking part, increasing the contact area between the tracks and the ground, and improving the grip of the electric tracked scooter; installing the lithium battery pack and motor at the top center of the sub-frame lowers the center of gravity of the electric tracked scooter, improving its stability.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 7 As shown, an electric tracked scooter includes a main frame 1 and a sub-frame 2, with the sub-frame 2 mounted on the main frame 1.

[0027] The main frame 1 has guide wheels 3 and drive wheels 4 installed at its front and rear ends, respectively, and tracks 5 are installed on the guide wheels 3 and drive wheels 4. The front of the subframe 2 has a "T"-shaped front handlebar 6, and an electric vehicle shifter speed controller 7 is installed on the front handlebar 6. The top center of the subframe 2 has a lithium battery pack 8, a motor 9 and a motor controller 10. The lithium battery pack 8 is connected to the motor 9 and the motor controller 10 by wires to supply power. The motor controller 10 is connected to the electric vehicle shifter speed controller 7 and the motor 9 by cables to control the working state of the motor 9. The motor 9 is connected to the drive wheel 4 through a transmission mechanism 11. Specifically, the transmission mechanism 11 includes a drive gear installed on the motor drive shaft, a driven gear installed on the drive wheel axle, and a transmission chain. The transmission chain meshes with the drive gear and the driven gear.

[0028] The user flicks the electric vehicle speed controller 7 with their finger. The motor controller 10 receives the control signal from the electric vehicle speed controller 7 and controls the speed of the motor 9. The motor 9 drives the drive wheel 4 to rotate through the transmission mechanism 11, which in turn drives the track 5 to travel on the ground.

[0029] The electric tracked scooter uses tracks as the walking part that contacts the ground, simplifying the structure of the walking part, increasing the contact area between the tracks and the ground, and improving the scooter's grip. The lithium battery pack and motor are installed at the top center of the subframe, lowering the center of gravity of the electric tracked scooter and improving its stability.

[0030] An auxiliary support wheel 12 is installed on each of the two rear sides of the main frame 1. The auxiliary support wheel 12 supports the rear of the track 5, reduces the sag of the track, allows the track to better cooperate with the drive wheel and guide wheel, and can share the weight of the vehicle, thus improving driving stability.

[0031] The top of the subframe 2 is also equipped with multiple foot pedal anti-slip strips 13. The foot pedal anti-slip strips 13 have a U-shaped cross section and several isosceles trapezoidal anti-slip teeth 1301 at the top. The anti-slip teeth 1301 on the foot pedal anti-slip strips 13 have anti-slip and self-cleaning properties.

[0032] The top rear of the subframe 2 is also equipped with a trailer ring 14 to facilitate the towing of goods or luggage in conjunction with ropes or a skid.

[0033] A transmission mechanism protective cover 15 is installed on the side of the main frame 1, covering the transmission mechanism 11, to prevent the user's clothing from being caught in the transmission mechanism.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
