The invention discloses an in-vehicle seat belt detection device, which relates to the field of automobiles, and comprises a detection part located inside a seat belt box, which is in contact with the seat belt and used to detect the length of the seat belt being pulled out of the seat belt box by external force; and The controller is electrically connected to the pressure sensor in the seat, and the controller is also electrically connected to the detection part. A threshold is set in the controller, and the threshold is the length that the seat belt is pulled out when the seat belt protects the human body; when a person sits When on the car seat, the seat belt is pulled under the action of external force, and finally the male buckle is combined with the female buckle, the controller records the length of the seat belt pulled out detected by the detection part, and compares it with the threshold value; If the length of the seat belt being pulled out is greater than the threshold, it means that the seat belt is worn normally; The prompter on the seat sends out a prompt sound to remind the person on the seat to wear the seat belt correctly according to regulations.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a safety belt detection device in a vehicle. Background technique [0002] Automobile safety belt is exactly the device that is used to ensure that passengers and drivers reduce the injury of passengers when the vehicle body is violently bumped. The speed of modern cars is very fast. Once a collision occurs, the passenger's body will continue to move forward due to inertia, and will collide with the body in the car. In severe cases, the windshield may be smashed and fly forward out of the window. In order to prevent similar injuries from colliding, the public security department requires that the occupants in the front row of all cars must use seat belts, so that when a traffic accident occurs, the seat belts can play a fixed buffering effect on people to prevent secondary injuries. In modern cars, in order to prevent people from using seat belts in violation of regulations, a pressur...
