It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] Embodiment 1: As Figures 1 to 6 shown, the present invention discloses a wheeled tram driven by an electrostatic motor, which is characterized by comprising: A chassis frame 100; Wheels 200; An electrostatic motor 300, installed on both sides of the chassis frame 100, for outputting power to the wheels 200; Wherein, a high-voltage generator 500 is installed on the chassis frame 100 for outputting high-voltage current to the electrostatic motor 300. Specifically, the high-voltage current is high-voltage direct current; Wherein, the electrostatic motor 300 includes: A stator component 310, which includes a positive electrode 311 and a negative electrode 312 connected to the high-voltage generator 500, and an electrostatic field is formed between the positive electrode 311 and the negative electrode 312; Both the positive electrode 311 and the negative electrode 312 are multiple and are cross-distributed in the circumferential direction of the stator component 310; A rotor component 320, which is located inside the stator component 310, and the rotor component 320 includes a conductive sheet 3201; Wherein, the output end of the rotor component 320 is in transmission connection with the wheels 200, and the conductive sheet 3201 of the rotating component 320 can obtain charges from the positive electrode 311 and the negative electrode 312 of the stator component 310, so that the rotor component 320 is rotationally driven by the stator component 310 to drive the wheels 200 to rotate.

[0021] In this embodiment, the working principle of the electrostatic motor is as Figure 6As shown, when a DC high voltage is applied to the positive and negative electrodes respectively, an electrostatic field is formed between the positive and negative electrodes, and a corona region will be formed near the positive and negative electrodes (the electric field intensity near the electrodes is very large, which can ionize the nearby air to form a corona region, so that the air near the electrodes carries the same charge as the electrode plates); when the conductive sheet on the rotor component (which can carry charge in the electric field) passes through the positive electrode (or negative electrode), the conductive sheet will carry the same charge as the electrode plate, so a repulsive force will be generated between the conductive sheet and the electrode (positive electrode), pushing the rotor component to move. At the same time, the charged rotor will move to the next stage (negative electrode) under the action of the electric field. The charge on the conductive sheet is first neutralized and then introduced with the same charge as the negative electrode, so a repulsive force will be generated between the conductive sheet and the electrode (negative electrode), pushing the rotor component to move. In this way, a continuous driving force is formed through repeated cycles; In this embodiment, in terms of the wiring method, the output end of the battery is connected to the input end of the high-voltage generator. The DC electromotive force generated by the battery can reach the voltage range required to drive the electrostatic motor to operate after being amplified by the high-voltage generator. The output end of the high-voltage generator is connected to the electrostatic motor. The structure and principle are simple, and no complex components and control circuits are required; In this embodiment, by connecting to high-voltage direct current, an alternating electric field is formed in the circumferential direction. The charged conductive sheet will be forced to move in the high-voltage electric field, thereby driving the rotor component to rotate, driving the wheels to rotate, and realizing the displacement of the wheeled tram; In this embodiment, the electrostatic motor itself is a low-speed motor. Therefore, the wheeled tram in this embodiment can do without a speed reducer, can adapt to resistance, has low power consumption in the low-speed or stalled state. In addition, a speed reducer can be additionally installed to increase the driving torque; By adopting the above technical solutions, the wheeled tram prepared by the present invention uses an electrostatic motor to drive the wheels to roll to realize the movement of the wheeled tram. By using this method of driving the tram with an electrostatic motor, compared with the traditional method of driving with an electromagnetic motor, it can adapt to resistance, has low power consumption in the low-speed or stalled state, the motor does not heat up, and has high efficiency when driving at low speed; Compared with the traditional electromagnetic motor drive, the electrostatic motor has the characteristics of small current in the microampere level, low noise, high energy conversion efficiency, high power density, and almost no heat generation. It can avoid the problems of reduced efficiency and shortened life caused by temperature rise. At the same time, the energy consumption will be lower than that of the wheeled tram driven by the electromagnetic motor, especially in the low-speed or frequent start-stop state; In summary, the wheeled tram prepared by the present invention based on electrostatic motor drive has a significant improvement in energy consumption efficiency compared with the traditional electromagnetic motor, especially more remarkable in the low-speed operation or frequent start-stop conditions. In addition, the tram realizes the zero-heat generation characteristic in the low-speed or stalled conditions and can maintain high efficiency at low speeds.

The fins serve as the positive electrode 311 and the negative electrode 312 and are cross-distributed circumferentially between the front support frame 3101 and the rear support frame 3102. The positive electrode 311 is electrically connected to the positive pole of the high-voltage generator 500 through a positive-pole connection wire, and the negative electrode 312 is electrically connected to the negative pole of the high-voltage generator 500 through a negative-pole connection wire; An included angle is formed between the fins and the front support frame 3101 and the rear support frame 3102.

[0024] In this embodiment, the front support frame and the rear support frame are insulators, and adjacent positive and negative electrodes will not transfer charges due to being fixed on the front support frame and the rear support frame; In this embodiment, a cross-shaped frame structure is provided on the radial inner sides of the front support frame and the rear support frame to ensure the structural stability of the front support frame and the rear support frame; In this embodiment, the fins are made of carbon fiber thin plates, which have better structural strength and are lighter; In this embodiment, the positive and negative electrodes are obliquely arranged carbon fiber thin plates evenly distributed circumferentially, and are alternately connected to the positive and negative poles of the high-voltage direct current, so that a high-voltage electric field can be formed between the thin plates; By adopting the above technical solution, the function of the conductive sheet is to carry charges and thus move under forced motion between the electrodes, so that the rotor component obtains torque to drive the wheels to rotate.

[0027] In this embodiment, the conductive sheets are made of carbon fiber thin plates; By adopting the above technical solution, a conductive sheet is used. The conductive sheet can carry more charges. The conductive sheet is a carbon fiber thin plate. Carbon fiber can conduct electricity, has very high strength, and is lighter. In addition, according to actual needs, the length of the conductive sheet in the transverse direction can be further increased, so as to obtain a greater electrostatic driving torque.

[0028] Embodiment 4: This embodiment provides a wheeled tram driven by an electrostatic motor. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0029] Furthermore, the frame assembly includes: An outer frame, which includes an outer frame one 3202 and an outer frame two 3203. Both the outer frame one 3202 and the outer frame two 3203 are annular. The conductive sheet 3201 is located between the outer frame one 3202 and the outer frame two 3203; An inner frame, which includes an inner frame one 3204 and an inner frame two 3205. Both the inner frame one 3204 and the inner frame two 3205 are in a hollow disk structure; A support frame one, fixedly connected between the outer frame and the inner frame Wherein, a rotating shaft 3206 is fixedly installed between the inner frame one 3204 and the inner frame two 3205.

[0030] In this embodiment, the conductive sheet is connected between the outer frame one and the outer frame two; In this embodiment, support frames one are provided between the inner frame one and the outer frame one, and between the inner frame two and the outer frame two; In this embodiment, the support frame one is a cross-shaped frame structure to ensure the structural stability of the inner frame and the outer frame; By adopting the above technical solution, through the mutual cooperation of the inner frame and the outer frame, while fixing the conductive sheet, the structural strength of the entire rotor is strengthened, and power is output to the wheels through the rotating shaft.

[0031] Embodiment 5: This embodiment provides a wheeled tram driven by an electrostatic motor. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0032] Furthermore, both the front support frame 3101 and the rear support frame 3102 are fixedly connected to the chassis frame 100; Both ends of the rotating shaft 3206 respectively penetrate through the front support frame 3101 and the rear support frame 3102 and are connected with the wheels 200; Wherein, the rotating shaft 3206 is respectively rotatably connected to the front support frame 3101 and the rear support frame 3102.

[0033] In this embodiment, the outer edges of the front support frame and the rear support frame are connected and fixed to the chassis frame through a clamping structure.

[0034] Embodiment 6: This embodiment provides a wheeled tram driven by an electrostatic motor. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0035] Furthermore, it further includes: A brush 400, located on the positive electrode 311 and the negative electrode 312 and / or the conductive sheet 3201, and capable of making a flexible connection between the electrode and the conductive sheet 3201; The brush 400 is made of silver wire and is located on the electrode, and its cantilever end contacts the conductive sheet 3201 radially inward.

[0036] By adopting the above technical solution, as Figure 5 shown, the magnitude of the electrostatic driving force of the electrostatic motor also depends on the gap between the rotor and the stator. The smaller the gap, the closer the rotor is to the electrode (the closer to the electrode, the stronger the corona field), so that more charges can be obtained. To avoid rubbing, at the same time, in order to obtain a larger electrostatic driving torque, the gap between the rotor component and the stator component must be reduced. However, due to the machining and assembly precision problems, the gap cannot be made very small. By radially obliquely inserting a silver wire brush into the electrode, a flexible contact between the rotor and the electrode is realized, and the gap between the rotor conductive sheet and the electrode is 0. Although the use of the brush will increase the resistance of the rotor, the increase in the electrostatic force is greater than the increase in the resistance, obtaining a larger electrostatic driving torque, effectively improving the starting performance, running stability, efficiency and energy consumption, noise and vibration control, etc. of the wheeled tram.
