[0073] The resistor R3 is arranged between the Hall element U4 and the power output end VDD, the resistor R12 is arranged between the Hall element U4 and the output end VDD, and the capacitor C6 and the diode D3 are arranged between the resistor R12 and the output end VDD.

[0074] Embodiment 2

[0075] This embodiment is an improvement based on embodiment 1, for details, please refer to Figures 1-5 , and further comprising:

[0076] The handle cover 1 is sleeved on the outer surface of the handle 3;

[0077] A gap is arranged between one end of the handle cover 1 and the outer surface of the rotating head 5;

[0078] The upper cover 8 is arranged inside the cavity together with the gear block 7.

[0079] The upper end of the upper cover 8 is connected to the inner wall of the rotating head 5.

[0080] One end of the gear block 7 is slidingly connected to the inside of the rotating rod 4.

[0081] Since the gear design is mostly adapted to a small number of vehicle models, drivers unfamiliar with the gear design may mistakenly touch the handle 3. For example, in a large number of vehicle models, the gear position is generally designed as a wiper switch, so when the driver wants to turn on the wiper, the handle 3 will be mistakenly touched. Although the vehicle interior design has a gear shifting logic, for example, when driving from R gear to D gear, the vehicle will automatically be in N gear and prompt the driver to shift gears again, but this design does not have a teaching effect, and drivers unfamiliar with the gear design will still make mistakes next time.

[0082] To this end, the air bag 20 is arranged between the rotating head 5 and the decorative ring 2. When the vehicle is driving, the air pump is installed inside the cavity, and air is transmitted to the air bag 20 by the air pump, so that the air bag 20 is inflated, and the air bag 20 is respectively in contact between the rotating head 5 and the decorative ring 2, so that the air bag 20 increases the friction between the rotating head 5 and the rotating rod 4, and when the driver wants to touch the handle 3 and the decorative ring 2 during driving, the decorative ring 2 will be blocked from being touched to one side due to the large friction between the air bag 20 and the decorative ring 2, so that the driver thinks that the touch position is a gear design, not a wiper, which warns and guides the driver, and further enhances the driver's memory of this position, thereby playing a teaching role.

[0083] Embodiment 3

[0084] This embodiment is an improvement based on embodiment 2. For details, please refer to Figures 1-5 The gap is also provided with an air bag 20, and the air bag 20 is inflated and in contact with the two ends of the rotating head 5 and the decorative ring 2.

[0085] One end of the decorative ring 2 is provided with an inclined surface, and the width of the gap gradually decreases near the axis of the rotating rod 4.

[0086] According to Figure 2When the driver uses more force, the handle 3 and the decorative ring 2 will still swing, and therefore, in order to increase the friction between the air bag 20 and the decorative ring 2, the end of the decorative ring 2 is provided as a reverse conical surface, when the driver continues to swing the decorative ring 2 to one side, the end of the decorative ring 2 close to the axis of the rotating rod 4 gradually reduces the distance between the rotating head 5, so as to increase the friction with the air bag 20, and further make the driver realize that this design cannot be randomly swung in the driving state, so as to further warn and guide the driver and make the driver remember this place more deeply.

[0087] Embodiment 4

[0088] This embodiment is an improvement based on embodiment 3, and specifically, please refer to Figures 1-5 The end of the rotating head 5 is further provided with a limiting cavity 19, and the limiting cavity 19 is internally provided with a button 18 for sending a wiper signal;

[0089] The air bag 20 includes an outer air bag and an inner air bag;

[0090] The outer air bag is used to fill the gap;

[0091] The inner air bag is used to fill the inside of the limiting cavity 19 and abut on the button 18;

[0092] The rotating rod 4 and the gear pin 6 are further provided with an adjusting device;

[0093] The adjusting device includes a transmission sleeve 13, a moving groove 14, a protrusion 15, a shaft rod 16 and an adjusting sleeve 17;

[0094] One end of the transmission sleeve 13 is connected with the gear pin 6, the transmission sleeve 13 is hollow inside, the shaft rod 16 is slidably connected inside the transmission sleeve 13, one end of the shaft rod 16 is provided with the protrusion 15, and one end of the protrusion 15 abuts on the inner wall of the transmission sleeve 13;

[0095] The other end of the shaft rod 16 is connected with the adjusting sleeve 17, the outer surface of the adjusting sleeve 17 is connected with the air bag 20, and the air bag 20 expands to drive the adjusting sleeve 17 to slide;

[0096] One end of the rotating rod 4 is slidably connected inside the adjusting sleeve 17.

[0097] In order to avoid the driver from forcibly swinging the decorative ring 2 with more force, the transmission sleeve 13 is provided between the rotating rod 4 and the gear pin 6, and specifically according to Figure 2As shown, when the vehicle starts, the air bag 20 inflates and expands, so that the air bag 20 fills the gap between the decorative ring 2 and the rotating head 5, and the expanded air bag 20 also moves the limiting cavity 19 to the adjusting sleeve 17, so as to pull the shaft rod 16 and the protruding block 15 to slide to the right through the adjusting sleeve 17. When the protruding block 15 moves to the moving groove 14, the moving groove 14 observes the transmission sleeve 13, so that when the driver forcibly pushes the decorative ring 2 to swing the rotating rod 4, the rotating rod 4 swings the adjusting sleeve 17 and the shaft rod 16, and the shaft rod 16 swings the protruding block 15, the protruding block 15 will only slide in the moving groove 14 and will not press the transmission sleeve 13 to swing, so as to avoid the driver using too much force to forcibly push the decorative ring 2 to issue a gear shifting instruction, thereby improving the durability of the PCB module board 11 and reducing the risk of damage to the PCB module board 11 caused by logic errors.

[0098] It needs to be specially pointed out that when the vehicle needs to be shifted after stopping moving, the air pump will extract the air at the air bag 20, so as to push the decorative ring 2 to swing the decorative ring 2, the rotating rod 4, the adjusting sleeve 17, the shaft rod 16, and the protruding block 15. At this time, the protruding block 15 is inserted into the inner wall of the transmission sleeve 13, so that the transmission sleeve 13 is pressed to swing by the protruding block 15 touching the inside of the transmission sleeve 13, the protruding block 15 swings the gear pin 6, and the gear pin 6 swings the magnet 10 to trigger the Hall element on the PCB module board 11.

[0099] It needs to be specially pointed out that the reset spring is connected between the adjusting sleeve 17 and the rotating head 5, so that when the air bag 20 deflates, the adjusting sleeve 17 and the shaft rod 16 are pulled back by the reset spring;

[0100] The air bag 20 includes an outer air bag and an inner air bag. The outer air bag is used to fill the gap, and the inner air bag is used to fill the inside of the limiting cavity 19 and touch the button 18. Therefore, when the air fills the outer air bag and the inner air bag, according to Figure 2 As shown, one end of the outer air bag touches the ground of the rotating head 5, so that the outer air bag can only expand to the decorative ring 2, thereby moving the adjusting sleeve 17 by the outer air bag.

[0101] In the driving state, when the driver uses too much force to push the decorative ring 2 to swing, the decorative ring 2 will squeeze the air bag 20 to expand again, so that the air bag 20 squeezes the button 18, the button 18 is connected with the wiper wire, so as to make the button 18 send a wiper signal, so as to complete the wiper action, and avoid the driver using too much force to push the decorative ring 2 to trigger the wiper.
