[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] As Figures 1-5 shown in the utility model embodiment, comprising:

[0019] A high-voltage loop conduction control device, comprising inner rotor 1, first inner terminal 2, second inner terminal 3, outer sleeve 4, elastic conductive reed 5, rotating shaft 6, driver 7, series electrode piece 8, series circuit 9, the inner rotor 1 has two and is cylindrical, the outer circumferential surface of the inner rotor 1 is provided with first inner terminal 2 and second inner terminal 3 in pairs, each inner rotor 1 is coaxially arranged in an outer sleeve 4, the inner rotor 1 is insulated with the outer sleeve 4, a pair of elastic conductive reed 5 is arranged on the inner wall of the outer sleeve 4, two inner rotors 1 are coaxially connected through rotating shaft 6 and drive external driver 7, the outer wall of the outer sleeve 4 is provided with a pair of series electrode piece 8 for electrically connecting each elastic conductive reed 5, the inner rotor 1 is electrically connected with the elastic conductive reed 5 by the self-rotating mode and is externally connected with a series circuit 9 through the series electrode piece 8.

[0020] Wherein, the series circuit 9 is provided with an electric appliance 91 and a high-voltage battery pack 92, and the inner rotor 1 is arranged at the positive and negative poles of the electric appliance 91 respectively.

[0021] Further, the interval angle between the first inner terminal 2 and the second inner terminal 3 is 180°, the first inner terminal 2 is provided with at least three rows along the axial direction, the second inner terminal 3 is provided with at least three rows along the axial direction, the interval angle between adjacent first inner rotors 1 is a, and the interval angle between adjacent second inner rotors 1 is also a; the inner rotor 1 is divided into positive rotors and negative rotors, and there is a a-angle difference in sequence between the first inner terminal 2 on the positive rotor and the first inner terminal 2 on the negative rotor in the clockwise direction.

[0022] Further, the first inner terminal 2 and the second inner terminal 3 are both helical structure springs semi-inlaid on the inner rotor 1, and the helical structure spring is in contact with the first inner terminal 2 and the second inner terminal 3 with the same length.

[0023] As Figure 3 shown, in state 1, the positive and negative electrodes are disconnected at the same time;

[0024] As Figure 4 shown, in state 2, the rotating shaft 6 rotates clockwise, the positive electrode is connected first, and the negative electrode is still in the separation state;

[0025] AsFigure 5 As shown, in state 3, the rotating shaft 6 continues to rotate clockwise, the positive terminal remains in the connected state, and the negative terminal also enters the connected state.

[0026] The main features of this product are:

[0027] The relay is replaced by driving the inner rotor 1 to rotate via the driver 7.

[0028] There is a clockwise positional difference of angle 'a' between the first inner terminal 2 on the positive rotor and the first inner terminal 2 on the negative rotor. The inner rotor 1 on the negative side makes contact first, thus establishing circuit continuity. The inner rotor 1 on the positive side makes contact later, thus establishing output continuity. At the same time, the inner rotor 1 on the negative side remains connected, ensuring safe contact and rapid response.

[0029] When the driver 7 rotates in the reverse direction, the inner rotor 1 on the positive side will first separate, breaking the circuit; the inner rotor 1 on the negative side will then separate, completely disconnecting the output connection.

[0030] In the product design, the inner terminals are located on the positive and negative lines respectively. The two sets of connection structures use a rotating shaft 6 to achieve synchronous rotation switching, and construct an angle difference between the first inner terminals 2 of the positive and negative poles to achieve positional difference control. This ensures that during the operation, there will always be a situation where one end contacts first, thereby achieving time-sharing control.

[0031] In summary, this utility model provides a high-voltage circuit conduction control device. The position of the inner rotor 1 is controlled by rotating the central rotating shaft 6, thereby achieving output control of the high-voltage circuit. It replaces relays, saving on intermediate control processes, and achieves integrated control through position limitation.
