Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1~Figure 6 As shown, the safety belt buckle fastening detection device includes a PCB board 1, which is characterized in that it also includes a slider 2 slidingly sleeved on the PCB board 1, and the front side of the PCB board 1 is along the sliding direction of the slider 2 A normally open copper foil 3, a common copper foil 4 and a normally closed carbon film 5 are arranged at equal intervals in sequence, and a reed 6 is connected to the slider 2, and two abutting plates are arranged on the reed 6. The contact pins 601 on the front of the PCB board 1, the two contact pins 601 are arranged along the sliding direction of the slider 2, the two contact pins 601 contact the PCB board 1 to form two contacts, and the distance between the two contacts is smaller than the normally open copper foil 3 The distance between the n...

Abstract

The invention relates to a safety belt buckle detection device which comprises a PCB and a sliding block, the PCB is provided with a normally-open copper foil, a common copper foil and a normally-closed carbon film, the sliding block is connected with a reed, the reed is provided with two contact pins, the two contact pins abut against the PCB to form two contacts, and the two contacts are connected with the PCB. A vehicle-mounted indicating lamp and a power supply are connected in series between the normally-open copper foil and the common copper foil, when two contact pins of the reed abut against the normally-open copper foil and the common copper foil respectively, the indicating lamp is lightened, and when two contact pins of the reed abut against the normally-closed carbon film and the common copper foil respectively, a divider resistor and the power supply are connected in series between the normally-closed carbon film and the common copper foil. The automobile central control chip detects the voltage between the divider resistor and the normally-closed carbon film and further calculates the resistance value of the normally-closed carbon film connected into a circuit, and a push handle is connected to the sliding block and used for being connected with a release device in a safety belt mortise lock.

Description

technical field [0001] The invention belongs to the technical field of devices, and in particular relates to a seat belt buckle fastening detection device. Background technique [0002] Seat belts play a vital role in protecting the safety of passengers during driving. In the event of an accident, if the seat belts can be tightened immediately to absorb most of the impact, the safety of passengers will be greatly improved. coefficient, but the connection structure of the seat belt has a certain loose space, that is, when an accident occurs, the passenger moves forward and pulls the seat belt to make the seat belt stretch quickly for a certain distance, and then the seat belt self-locking and tightening function will be triggered , and at this time, the first time of the impact has passed, and the passenger may hit the airbag heavily, still causing relatively serious injuries. [0003] Therefore, if the trigger time of the seat belt self-locking function and tightening funct...
