Its special feature is that a current amplification circuit is connected between the power generation indicator light terminal, the positive pole of the power supply and the generator coil terminal. The advantage is that the circuit structure is simple, adaptable to various vehicle charging indicator lights, and can ensure the normal power generation of the automobile generator. However, when the automobile AC generator regulator is in use, it is installed inside the motor, and the automobile AC generator regulator itself has a connecting wire connected to the internal interface of the motor. The connecting wire is in a suspended position at this time, and the connecting wire is not positioned, which can easily cause the connecting wire of the automobile AC generator regulator to wear, affecting the normal transmission of the automobile AC generator regulator signal, resulting in the automobile AC generator regulator being unable to be used normally and shortening its service life.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1: Please refer to Figure 1-5 : In this embodiment, a PWM-based automobile AC generator regulator includes a first curved plate 1 and a through-port 4. The through-port 4 is processed on the outer wall of the first curved plate 1. The automobile AC generator regulator 5 is fixedly connected to the right side of the first curved plate 1. How to operate and use the automobile AC generator regulator 5 is already existing technology. The model is selected according to usage requirements and will not be elaborated on. The control structure 2 is connected to the top front of the automobile AC generator regulator 5, and the installation structure 3 is connected to the right side of the automobile AC generator regulator 5.

[0021] The control structure 2 includes a vertical plate 201 and a bracket 202. The bottom of the vertical plate 201 is fixedly connected to the top front of the automobile AC generator regulator 5. The inner wall of the vertical plate 201 is rotatably connected to the left side of the outer wall of the bracket 202. The left side of the outer wall of the bracket 202 is subjected to force and rotates through the pin on the inner wall of the vertical plate 201. The right side of the bracket 202 is fixedly connected to a square plate 203. The inner wall of the square plate 203 is threadedly connected to a bolt 204. The bottom of the outer wall of the bolt 204 is threadedly connected to a straight plate 6. The bolt 204 fixes the square plate 203 and the straight plate 6. The bottom of the straight plate 6 is fixedly connected to the top front of the automobile AC generator regulator 5.

[0022] By controlling the structure 2, the bolt 204 is rotated upward through the square plate 203, so that the bottom of the outer wall of the bolt 204 is separated from the top of the straight plate 6. Then, the bracket 202 is rotated upward through the pin on the inner wall of the vertical plate 201, and then the wire 7 is bent forward, so that the wire 7 is placed under the bracket 202. Then, the bracket 202 is rotated downward, so that the bottom of the square plate 203 is in contact with the top of the straight plate 6. Then, the bolt 204 is threaded through the square plate 203 from top to bottom and is threadedly connected to the top of the straight plate 6, completing the pressure holding of the wire 7 by the bracket 202. This can prevent the wire 7 from being worn by the automobile AC generator due to a large bending arc, ensure the normal use of the automobile AC generator regulator, and guarantee the service life.

[0023] A wire 7 is electrically connected to the top rear of the automobile AC generator regulator 5, and a protective pad 9 is fixed to the rear end face of the automobile AC generator regulator 5. The protective pad 9 is made of rubber. The mounting structure 3 includes a second curved plate 301 and a straight cylinder 302. The left side of the second curved plate 301 is fixed to the right side of the automobile AC generator regulator 5. The inner wall of the second curved plate 301 is slidingly connected to the outer wall of the straight cylinder 302. The straight cylinder 302 slides left and right under the force through the groove on the inner wall of the second curved plate 301. A circular ring 303 is threadedly connected to the front of the outer wall of the straight cylinder 302. The circular ring 303 rotates back and forth under the force through the thread on the outer wall of the straight cylinder 302.

[0024] Working principle:

[0025] Car Alternator Regulator Installation:

[0026] The rear of the automobile AC generator regulator 5 is fitted with the internal connection of the automobile AC generator, and then the bolt passes through the through-hole 4 from the right front to the rear and is fixed to the connection of the automobile AC generator. Then the ring 303 is rotated forward through the outer wall thread of the straight cylinder 302 to make the ring 303 disengage from the front of the second curved plate 301. Then the straight cylinder 302 slides left and right on the inner wall of the second curved plate 301 to adjust its position. Then the thread passes through the second straight cylinder 302 and is fixed to the connection of the automobile AC generator. Then the ring 303 is rotated backward through the outer wall thread of the straight cylinder 302 to make the rear end face of the ring 303 press against the front of the second curved plate 301, so that friction is generated between the ring 303 and the second curved plate 301, so that the straight cylinder 302 is fixed in position. If it shakes during subsequent use, the protective pad 9 will be clamped at the connection between the automobile AC generator regulator 5 and the automobile AC generator to play an anti-wear role.

[0027] Automobile alternator regulator wire connection and control:

[0028] The bolt 204 is rotated upward through the square plate 203 so that the bottom of the outer wall of the bolt 204 is separated from the top of the straight plate 6. Then the bracket 202 is rotated upward through the pin on the inner wall of the vertical plate 201. Then the wire 7 is bent forward so that the wire 7 is placed under the bracket 202. Then the bracket 202 is rotated downward so that the bottom of the square plate 203 is in contact with the top of the straight plate 6. Then the bolt 204 is threaded through the square plate 203 from top to bottom and is threadedly connected to the top of the straight plate 6. The bracket 202 completes the pressure on the wire 7, which can prevent the wire 7 from being worn by the car's AC generator due to the large bending curvature. Then the top of the wire 7 is connected to the connection point of the car's AC generator.

[0029] The automobile alternator regulator 5 works by transmitting a pulse width modulation signal (PWM) to the automobile alternator through a wire, thereby ensuring a stable voltage output.

[0030] Example 2: Please refer to Figure 1-5 In this embodiment, an automobile AC generator regulator further includes a cover plate 8, the outer wall of the cover plate 8 is fixedly connected to the front of the inner wall of the automobile AC generator regulator 5.

[0031] Working principle:

[0032] The cover plate 8 has a plurality of notches on the front side, so that the thickness of the position is reduced, so that the heat inside the automobile AC generator regulator 5 can be discharged through the notches.

[0033] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
