Optionally, the sensor is relatively fixedly connected with the head pipe, and the sensor is fixedly connected with the stand pipe; optionally, the sensor with the first pipe relatively fixed connection, inductor A with inductor B respectively with two spinal branch post fixed connection or with the both ends fixed connection of fork shoulder. Both solutions are essentially the same, both of which are such that the relative displacement between the susceptor and the sensor occurs as the fork rotates.
Preferably, the first inductor and the second inductor are symmetrically distributed on two sides of the head pipe, and when the head pipe swings, the sensors are positioned on a central line of a connecting line of the first inductor and the second inductor; preferably, when the vehicle head swings, the inductor A and the inductor B are symmetrically distributed, and the inductor is positioned on a central line of a connecting line of the inductor A and the inductor B.

As shown in fig. 2-3, a sensor 20, in this case a magnet, is welded directly in front of the riser 11, and the corresponding sensor is a magnetic sensor; two sensors, namely a sensor A21 and a sensor B22 are symmetrically fixed at two ends of the sensor 20 on the first pipe 4, the sensor A21 is arranged on the left side of the central axis of the vehicle body where the sensor 20 is arranged at 30 degrees, the sensor B22 is arranged on the right side of the central axis of the vehicle body where the sensor 20 is arranged at 30 degrees, the two sensors are respectively connected with the first pipe 4 through an 8-shaped rubber ring, namely the sensor A21 is connected with the sensor A rubber ring 211, the sensor B22 is connected with the sensor B rubber ring 221, namely the sensors are sleeved in one rubber ring, the first pipe 4 is sleeved in the other rubber ring, the sensors can move along the circumference on the first pipe 4 by moving the rubber ring, and if the system is to be more sensitive, the 30 degrees can be reduced, otherwise, the sensors can be increased. A control switch A is connected with the inductor A21 and controls the power supply of the rear wheel motor A31 to be switched on and off, a control switch B is connected with the inductor B22 and controls the power supply of the rear wheel motor B32 to be switched on and off. The circuit of the inductor A21 is connected with the control switch A, and the circuit of the inductor B22 is connected with the control switch B.
When a driver turns the head of the electric vehicle to the left, the vertical pipe 11 of the electric vehicle rotates to the left along with the rotation of the head of the electric vehicle, the sensor 20 on the vertical pipe is driven to turn to the left until the sensor 20 is sensed by the sensor A21 on the left side, a signal is sent to the control switch A, after the control switch A receives the signal, the power supply of the rear wheel motor A31 (the turning inner side wheel at the moment) is disconnected, and the rear wheel motor B32 still runs at the original speed, so that differential turning is realized. After the turning is finished, the stand pipe 11 is reset, the sensor 20 on the stand pipe is far away from the sensor A21 until the sensing range of the sensor A21 is exceeded, the sensor A21 stops sending signals to the control switch A, the rear wheel motor A31 recovers power supply, and the electric vehicle continues to run in a straight line.
The principle of turning right is the same as above.
Example two: the inductor A21 is connected with the control switch B through a circuit, the inductor B22 is connected with the control switch A through a circuit, when the vehicle head swings, the inductor A21 and the inductor B22 can both feel the inductor 20, when the vehicle head rotates by a certain angle, the distance between one inductor and the inductor 20 is increased, the inductor 20 cannot be felt, and therefore signals are stopped being sent to the control switch connected with the inductor. Except for the above differences, the other conditions were the same as in example one.
When a driver turns the head of the electric vehicle to the left, the vertical pipe 11 of the electric vehicle rotates to the left along with the rotation of the head of the electric vehicle, the sensor 20 on the vertical pipe is driven to turn to the left until the sensor 20 cannot be sensed by the sensor B22 on the right side, the signal is stopped to be sent to the control switch A, after the control switch A cannot receive the signal, the power supply of the rear wheel motor A31 (the turning inner side wheel at the moment) is disconnected, and the rear wheel motor B32 still runs at the original speed, so that the differential turning is realized. After the turning is finished, the stand pipe 11 is reset, the sensor 20 on the stand pipe is close to the sensor B22 until the stand pipe enters the sensing range of the sensor B22, the sensor B22 continues to send signals to the control switch A, the rear wheel motor A31 recovers power supply, and the electric vehicle continues to run in a straight line.

As shown in fig. 5-6, the sensor 20 is provided right in front of the first pipe 4, the sensor 20 is connected to the first pipe 4 through an "8" shaped rubber ring, i.e. the sensor 20 is sleeved in one rubber ring, the first pipe 4 is sleeved in another rubber ring, the sensor 20 can be moved along the generatrix on the first pipe 4 by moving the rubber ring, if the system is to be more sensitive, the sensor 20 can be moved down to shorten the distance between the sensor 20 and the sensor, otherwise, the sensor 20 can be moved up. In this example, the sensor 20 is a magnet, and the corresponding sensor is a magnetic sensor; two inductors are symmetrically fixed on the fork shoulder 12, an inductor A21 and an inductor B22 are obliquely arranged upwards and forwards, the inductor A21 is arranged on the left side of the central axis of the vehicle body where the inductor 20 is arranged at 30 degrees, the inductor B22 is arranged on the right side of the central axis of the vehicle body where the inductor 20 is arranged at 30 degrees, and the two inductors are connected with the fork shoulder 12 in a welding mode. A control switch A is connected with the inductor A21 and controls the power supply of the rear wheel motor A31 to be switched on and off, a control switch B is connected with the inductor B22 and controls the power supply of the rear wheel motor B32 to be switched on and off. The inductor A21 is connected with the control switch B through a circuit, and the inductor B22 is connected with the control switch A through a circuit. When the vehicle head is swung, the sensor A21 and the sensor B22 cannot feel the sensor 20, and when the vehicle head rotates for a certain angle, the distance between one sensor and the sensor 20 is shortened, so that the sensor 20 can be felt.
When a driver turns the head of the electric vehicle to the left, the fork shoulder 12 of the electric vehicle rotates to the left along with the rotation of the head of the electric vehicle, the sensor on the electric vehicle is driven to turn to the left until the sensor B22 on the right side senses the sensor 20, a signal is sent to the control switch A, after the control switch A receives the signal, the power supply of the rear wheel motor A31 (the turning inner side wheel at the moment) is disconnected, and the rear wheel motor B32 still runs at the original speed to realize differential turning. After the turning is finished, the fork shoulders 12 reset, the two sensors cannot sense the existence of the sensor 20, the sensor B22 stops sending signals to the control switch A, the rear wheel motor A31 recovers power supply, and the electric vehicle continues to run in a straight line.
The principle of turning right is the same as above.
Example four: when the locomotive rotates for a certain angle, the distance between one inductor and the inductor 20 is increased, the inductor 20 cannot be sensed, and therefore signals are stopped being sent to the control switch connected with the inductor 20. Except for the above differences, the conditions were the same as those in the examples.
When a driver turns the head of the electric vehicle to the left, the fork shoulder 12 of the electric vehicle rotates to the left along with the head of the electric vehicle to drive the sensor on the electric vehicle to turn to the left until the sensor A21 on the left side cannot sense the sensor 20, the signal is stopped to be sent to the control switch A, the power supply of the rear wheel motor A31 (the turning inner side wheel at the moment) is disconnected after the control switch A cannot receive the signal, and the rear wheel motor B32 still runs at the original speed to realize differential turning. After the turning is finished, the fork shoulders 12 reset, the two sensors can feel the existence of the sensors 20, the sensor I21 continuously sends signals to the control switch I, the rear wheel motor I31 recovers power supply, and the electric vehicle continuously and linearly runs.
The principle of turning right is the same as above.
The above disclosure is only for the preferred embodiment of the present invention, but not intended to limit itself, and any changes and modifications made by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
