[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4This utility model provides a technical solution: an LED instrument panel with anti-theft function, comprising: a dial 1 for an electric vehicle, a wiring hole 2 at the bottom of the dial 1, and a small connector and a large connector fixedly connected inside the wiring hole 2. The small connector includes an alarm power positive interface 301, an anti-theft signal interface 302, a wheel signal interface 303, and a flasher interface 304. The large connector includes a common negative interface 401, an ignition lock interface 402, a right turn signal interface 403, a left turn signal interface 404, a headlight interface 405, and a single-wire interface 406. The left turn signal interface 404, headlight interface 405, and one-wire interface 406 are all electrically connected to the dial 1 via connecting wires. The alarm power positive interface 301 and the common negative interface 401 provide power to the dial 1. The ignition lock interface 402 works with the handle to realize the one-button start function. The anti-theft signal interface 302 and the wheel signal interface 303 work with the handle to realize the anti-theft lock motor function. The flasher interface 304 works with the turn switch to realize the flashing function of the turn signal when turning. The right turn signal interface 403 and the left turn signal interface 404 work with the left and right turn switches to give the turn signal. The headlight interface 405 works with the headlight switch to give the headlight working signal. The one-wire interface 406 communicates with the controller to realize the reception of signals such as speed, fault, and gear to drive the display of the corresponding functions of the dial 1.
[0019] A buzzer is fixedly connected inside the dial 1. A horn hole 5 is provided at the bottom of the dial 1 to facilitate a more convenient and louder alarm sound. The buzzer is set in correspondence with the horn hole 5. When the buzzer receives a signal, it can generate an alarm sound.
[0020] The small connector is model DJ7041F-1.8-11, which is electrically connected to the vehicle controller of the electric vehicle. The large connector is model DJ7061F-1.8-11.
[0021] The dial 1 is connected to an external remote control handle. The external remote control handle mainly includes a disarming button, a arming button, and a start button. Through the buttons on the remote control handle, signals can be sent to the dial 1 to make the dial 1 respond to the disarming, arming, or start actions.
[0022] Working principle: After receiving the arming command from the remote control handle, dial 1 pulls the anti-theft signal interface 302 low. Upon receiving the low-level signal, the small connector locks the motor. If the motor is rotated by an external force, it generates an induced electromotive force, which is sent to dial 1 through the wheel movement signal interface 303. Upon receiving this signal, dial 1 sounds an alarm through the buzzer. After receiving the disarming command from the remote control handle, dial 1 leaves the anti-theft signal interface 302 floating, and the vehicle controller's anti-theft port returns to the default high-level state. At the same time, dial 1 no longer detects the wheel movement signal voltage, and the arming state is deactivated. After receiving the one-button start signal command, dial 1 closes the ignition lock interface 402 in the large connector 4 with the MOS switch of the power supply, realizing the keyless start function of the vehicle.
[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
