DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following further details the specific implementation manners of this technical solution with reference to the drawings.

[0034] Embodiment:

[0035] SeeFigure 1 and Figure 2 , an electric scooter, comprising a frame body 1, a vehicle column 2, a front wheel 3 and a rear wheel 4. The vehicle column 2 is arranged on the front side of the frame body 1, and the vehicle column 2 is hinged relative to the frame body 1. The front wheel 3 is located below the vehicle column 2 and is rotatably connected. The vehicle column 2 rotates along the hinge axis to drive the front wheel 3 to swing synchronously to control the forward direction. The rear wheel 4 is rotatably connected to the rear end of the frame body 1. The front wheel 3 and the rear wheel 4 are located on the same level and cooperate to roll on the ground in contact with the ground to realize the movement and guidance of the frame body 1.

[0036] The vehicle column 2 is provided with a start seat 17. The start seat 17 is arranged at the upper end of the vehicle column 2. The start seat 17 can control the controller 6 to realize the start or shutdown of the motor. In this embodiment, the start seat 17 shown is operated by a key to realize the switch. Inserting the key into the start seat 17 changes the operating state of the electric scooter.

[0037] See Figure 3 and Figure 4 , the vehicle column 2 has an installation cavity 5 inside. The length direction of the installation cavity 5 is correspondingly arranged along the length direction of the vehicle column 2. A controller 6 is installed in the installation cavity 5. The vehicle column 2 is provided with heat dissipation holes 7. In this embodiment, the heat dissipation holes 7 are composed of multiple layers of heat dissipation gaps parallel to each other. The heat dissipation holes 7 penetrate into the installation cavity 5, and the positions of the heat dissipation holes 7 correspond to the position of the controller 6. The heat dissipation holes 7 are opened on the front side wall of the vehicle column 2, so that the natural wind force during the vehicle's travel can supply air circulation.

[0038] An audio speaker 14 is also installed in the installation cavity 5. The audio speaker 14 is fixed above the controller 6. The audio speaker 14 is connected to the controller 6. The audio speaker 14 can output audio for use. The vehicle column 2 is provided with a plurality of second installation holes 15. Each second installation hole 15 is opened on the front side wall of the vehicle column 2 corresponding to the position of the audio speaker 14. The plurality of second installation holes 15 are arranged at intervals along the length direction of the vehicle column 2. The second installation holes 15 are communicated with the installation cavity 5 for the audio speaker 14 to transmit sound to the external space.

[0039] The vehicle column 2 is provided with a mesh cover 16. The structure of the mesh cover 16 can allow air to circulate. The mesh cover 16 is located on the side of the vehicle column 2 where the heat dissipation holes 7 are opened. The mesh cover 16 abuts against the corresponding end face of the vehicle column 2 to cover the heat dissipation holes 7 and the second installation holes 15.

[0040] See Figure 3 and Figure 5The vehicle pillar 2 is provided with a mounting hole 8, which is located on the end surface of the vehicle pillar 2 away from the heat dissipation hole 7. The opening size of the mounting hole 8 is larger than the size of the controller 6, so that the controller 6 is embedded in the mounting cavity 5 through the mounting hole 8. A rear cover plate 9 is detachably connected to the mounting hole 8, and the rear cover plate 9 is adapted to the opening of the mounting hole 8, so that the rear cover plate 9 covers the opening of the mounting hole 8, thereby limiting the controller 6 from being separated from the mounting cavity 5.

[0041] The controller 6 is fixed in the installation cavity 5. The fixing method of the controller 6 is that a layer plate 10 is provided in the installation cavity 5. The length direction of the layer plate 10 is parallel to the length direction of the vehicle pillar 2. The layer plate 10 is provided with a positioning hole 11 adapted to the controller 6, and the penetration direction and position of the positioning hole 11 are aligned with the installation hole 8, so that after the controller 6 passes through the installation hole 8, it can be accurately embedded in the positioning hole 11, and the upper and lower inner walls of the positioning hole 11 are used to limit the sliding of the controller 6 along the length direction of the installation cavity 5, thereby realizing the fixed positioning of the controller 6.

[0042] The vehicle pillar 2 is provided with a plurality of mounting grooves 12. In the present embodiment, four mounting grooves 12 are provided. The four mounting grooves 12 are relatively symmetrically distributed in pairs, and the four mounting grooves 12 are distributed one by one on the outer walls of the vehicle pillar 2 on opposite sides. The length direction of the mounting groove 12 is parallel to the length direction of the vehicle pillar 2. A light strip 13 is installed in each mounting groove 12. The light strip 13 is laid along the length direction of the mounting groove 12. Each light strip 13 is connected to the controller 6. The speaker 14 has the function of playing audio. The speaker 14 is linked to the light strip 13 through the controller 6. The speaker 14 controls the light strip 13 to change color or flash through the controller 6.

[0043] The specific working process of this program is as follows:

[0044] The technical solution is to rotatably connect the front wheel 3 to the bottom of the vehicle pillar 2 so that the vehicle pillar 2 controls the steering of the front wheel 3 to achieve a change of direction during movement, and the rear wheel 4 is rotatably connected to the rear end of the frame body 1. The front wheel 3 and the rear wheel 4 rotate in coordination to ensure driving stability and flexibility, and use electricity as the driving force for moving forward. The controller 6 is installed in the installation cavity 5 of the vehicle pillar 2, and the structural layout is optimized to make the structure compact. The heat dissipation hole 7 is opened on the front side wall of the vehicle pillar 2. Based on the through position of the heat dissipation hole 7 corresponding to the position setting of the controller 6, the natural wind force when the vehicle is moving is used to dissipate heat through the heat dissipation hole 7, so that the temperature of the controller 6 can be continuously and effectively reduced, and the heat dissipation efficiency of the controller 6 is higher.
