detailed description

Referring to Fig. 1, the utility model discloses a speed-regulating handle of an electric vehicle with a wireless control switch type anti-theft device, including a speed-regulating handle of an electric vehicle, and a Hall element 1 and a controller are arranged inside the speed-regulating handle of an electric vehicle 2. There is a signal control line connected between the Hall element 1 and the controller 2, and also includes a wireless transmitting device and a wireless receiving control device. The wireless receiving control device is also set in the speed control handle of the electric vehicle. The wireless receiving control The device includes an on-off switch circuit 3 that is arranged on the signal control line and can control the on-off of the signal control line. The on-off switch circuit 3 is connected to and controlled by the wireless receiving control module 4. The wireless receiving control module 4 is connected to There is a receiving antenna 5 for receiving wireless signals; the wireless transmitting device includes a wireless transmitting control module 7 , a battery 9 connected to the wireless transmitting control module 7 , a transmitting antenna 6 and function keys 8 .

In this structure, the signal control line can be directly welded on the on-off switch circuit 3, thereby connecting the Hall element 1 and the controller to the on-off switch circuit 3. Of course, the device can also be connected through the following structure. The device can include a The input end and the output end are both plug terminals, the plug terminals are connected to the Hall element 1 and the controller 2 through the data line, and the on-off switch circuit 3 is connected to the Hall element 1 through the input end; The on-off switch circuit 3 is connected with the controller 2 through the output terminal. The above-mentioned structure is convenient for installing the anti-theft device on the car. It is only necessary to pull out the signal line connecting the Hall element 1 and the controller 2 of the original car, and the The signal line is connected to the input end, and another line is used to connect the output end to the controller 2 to complete the installation and realize the alarm function of the device.

As shown in Figures 2 and 3, the wireless transmission control module 7 includes a first RF radio frequency chip and a first MCU processing chip, and the first MCU processing chip encodes and modulates the instructions sent by the user through the function keys into a wireless signal It is transmitted through the first RF radio frequency chip.

As shown in Figures 4 to 7, the wireless receiving control device includes a second RF radio frequency chip, a second MCU processing chip and a memory, the second RF radio frequency chip is used to receive the wireless signal transmitted by the second RF radio frequency chip, and The signal is sent to the second MCU processing chip, and the second MCU processing chip processes, demodulates and decodes the signal to obtain the original control electrical signal, thereby controlling the on-off switch circuit 3, and the memory is used to store the code.

The principle of this device is briefly described, because there is a linear Hall element 1 with the size of the induction magnetic force line in the electric vehicle speed control handle, when the magnetic field changes, the Hall element 1 will output the corresponding voltage signal to the controller 2 through the signal control line, and the controller 2. Provide the corresponding current to the motor through the voltage signal, so as to achieve the purpose of starting the speed regulation. When the signal control line is cut off, the controller 2 will not receive the voltage signal output by the Hall element 1, so the controller 2 will No current is supplied to the motor, so the vehicle will not move.

The utility model is that a wireless receiving control device is installed in the ordinary electric vehicle speed regulation handle, and the wireless receiving control module 4 in the wireless receiving control device receives the control signal transmitted by the wireless transmitting device, thereby controlling the on-off switch The circuit 3 is turned on and off, and the on-off switch circuit 3 controls the on-off of the signal control line. Therefore, after the user's vehicle is stolen, the user only needs to press the function button to transmit the control signal to the wireless receiving control module 4, and the wireless receiving control module 4 The control module 4 controls the on-off switch circuit 3 to disconnect the signal control line, so that the electric car cannot be started or stops while driving, so that the thief cannot ride the car away, which plays a very good anti-theft effect.
