DETAILED DESCRIPTION

[0020] The present application will be further described in detail below with reference to the accompanying drawings and examples.

[0021] like Figures 1 to 3 As shown, this embodiment discloses an electrostatic induction generator, including a first disc 1, a second disc 2, a first transmission wheel 3, a first gear 4, a second gear 5, and a second transmission wheel 6. The first transmission wheel 3 is coaxially fixedly connected to the first gear 4, the first gear 4 is meshed with the second gear 5, and the second gear 5 is coaxially fixedly connected to the second transmission wheel 6. The first transmission wheel 3 is arranged to rotate synchronously with the first disc 1, and the second transmission wheel 6 is arranged to rotate synchronously with the second disc 2. When the first transmission wheel 3 drives the first gear 4 to rotate clockwise, the second gear 5 is driven by the meshing teeth of the first gear 4 to rotate in the opposite direction, that is, counterclockwise. The second gear 5 drives the second transmission wheel 6 to rotate synchronously counterclockwise, thereby causing the first disc 1, which is synchronously connected to the first transmission wheel 3, and the second disc 2, which is synchronously connected to the second transmission wheel 6, to move in opposite directions. Compared with the figure-eight rubber rope in the prior art, the transmission method through the meshing of the first gear 4 and the second gear 5 is more stable.

[0022] like Figure 1As shown, the first transmission wheel 3 and the first gear 4 are coaxially connected via a first transmission rod 7, and the second transmission wheel 6 and the second gear 5 are coaxially connected via a second transmission rod 8. A handwheel 20 is connected to the end of the first transmission rod 7 away from the first gear 4. The handwheel 20 facilitates the user to rotate the first transmission rod 7, thereby driving the first transmission wheel 3 and the first gear 4 to rotate. The first disc 1 is coaxially connected to the third transmission wheel 9, and the second disc 2 is coaxially connected to the fourth transmission wheel 10. A first synchronous belt 11 is wrapped around the outer peripheral walls of the first transmission wheel 3 and the third transmission wheel 9, and a second synchronous belt 12 is wrapped around the outer peripheral walls of the second transmission wheel 6 and the fourth transmission wheel 10.

[0023] like Figure 1 As shown, the protective box 13 is also included. The first gear 4 and the second gear 5 are respectively arranged inside the protective box 13. A first through-hole is provided on one side of the protective box 13 for the first transmission rod 7 to pass through, and a second through-hole is provided on the other side of the protective box 13 for the second transmission rod 8 to pass through. The first transmission rod 7 is provided with a first bearing 14. The inner ring of the first bearing 14 is sleeved on the outer peripheral wall of the first transmission rod 7, and the outer ring of the first bearing 14 abuts against the inner wall of the protective box 13. The second transmission rod 8 is provided with a second bearing 15. The inner ring of the second bearing 15 is sleeved on the outer peripheral wall of the second transmission rod 8, and the outer ring of the second bearing 15 abuts against the inner wall of the protective box 13. The protective box 13 protects the first gear 4 and the second gear 5. The first bearing 14 supports the first transmission rod 7, and the second bearing 15 supports the second transmission rod 8, ensuring the stability of the transmission.

[0024] like Figure 1 As shown, the system further includes a support plate 16 and a base 17. The third transmission wheel 9 is rotatably mounted on one end of the support plate 16 via a rotating shaft, and the other end of the support plate 16 is mounted on the base 17. The fourth transmission wheel 10 can be mounted on another support frame via another rotating shaft. The support plate 16 is provided with a third through-hole for the first transmission rod 7 to pass through. The first transmission rod 7 is equipped with a third bearing 18. The inner ring of the third bearing 18 is sleeved on the outer circumferential wall of the first transmission rod 7, and the outer ring of the third bearing 18 engages with the third through-hole.

[0025] like Figure 3 As shown, the first disc 1 and the second disc 2 are each inlaid with a metal sheet 19. In the prior art, the metal sheet 19 is generally attached to the first disc 1 and the second disc 2. During high-speed rotation, the metal sheet 19 is easily detached due to friction between the brush and the metal sheet 19, causing the entire device to have a poor electrification effect or even become unusable. In this solution, the metal sheet 19 is inlaid between the first disc 1 and the second disc 2, preventing the metal sheet 19 from detaching due to friction between the brush and the metal sheet 19.
