Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1 and 2, the utility model provides an anti-pulling system, which comprises a power supply vehicle, wherein a cable for supplying power is arranged on the power supply vehicle. A safety belt inserting sheet is hung on the cable.

The power supply vehicle is also provided with detection equipment. The detection equipment comprises a shell 1, wherein a controller, a safety belt socket 2 and a prompter are packaged in the shell 1. The seat belt socket 2 is exposed from the housing 1.

The controller is electrically connected to the seat belt socket 2. When the seat belt insert is inserted into the seat belt socket 2, the seat belt socket 2 outputs a normally open signal, otherwise a normally closed signal. The normally closed signal is converted into the normally open signal, so that the cable is retracted onto the power supply vehicle.

The controller is also electrically connected with the ECU of the electric power car, and the controller respectively controls the starting and stopping of the ECU based on the received normally open signal and normally closed signal. When the cable is not retracted, namely the safety belt socket 2 outputs a normally closed signal, the controller controls the ECU to be not operated, the power supply vehicle cannot be started, and the pulling-hanging accident is avoided. When the seat belt socket 2 outputs a normally open signal, the controller does not interfere with the operation of the ECU.

In addition, the controller outputs a prompt instruction based on the normally closed signal, and the prompter responds to the prompt instruction to prompt. The prompter comprises at least one of a display, a loudspeaker and a signal lamp, and is controlled by the controller to prompt. For example, the display displays subtitles to indicate whether the cable is retracted, the horn plays a specific voice prompt according to the period to indicate whether the cable is retracted, and the signal lamp displays red and green to indicate whether the cable is retracted.

Also important to explain is: firstly, for the use of the safety belt socket 2, the existing product which can be purchased is utilized, so that on one hand, the design and production process is simplified, and on the other hand, the safety belt has corresponding product standards to ensure the reliability. The second, conventional product case of the seat belt socket 2 is: when the safety belt inserting sheet is inserted into the safety belt inserting sheet, normally closed signals are output, normally open signals are output in the scheme in an opposite mode, and a NOT gate is added to improve safety margin. Because once the system circuit breaks, the controller also receives the normally closed signal, and prompts that the cable has been retracted, whether the cable is retracted cannot be identified, and the risk of pulling is brought. According to the scheme, after the circuit of the system is broken, the signal is changed from normally open to normally closed, the prompter can always prompt that the cable is not retracted, the fault is conveniently checked, and the pull-up risk is avoided.

In summary, the anti-pulling and hanging device can play a role in prompting, and a cable can be clearly signaled after being retracted.
