The invention discloses an in-vehicle safety belt detection device and relates to the field of automobiles. The device comprises a detection part, and a controller, wherein the detection part is located in a safety belt box, in contact connection with a safety belt and used for detecting the length of the safety belt pulled out of the safety belt box by external force, the controller is electrically connected with a pressure sensor in the seat, the controller is further electrically connected with the detection part, a threshold value is set in the controller, and the threshold value is the length of the safety belt pulled out when the safety belt protects the human body, when a person sits on an automobile seat, the safety belt is pulled under the action of external force, and finally inthe process that a male buckle and a female buckle are combined, the controller records the pulled-out length, detected by the detection part, of the safety belt and compares the pulled-out length with a threshold value; if the pulled-out length of the safety belt is larger than the threshold value, that the safety belt is normally worn is indicated, if the pulled-out length of the safety belt issmaller than the threshold value, that a person on the seat does not wear the safety belt normally is indicated, at the moment, the controller can make a prompter in the automobile give out a prompt tone to remind the person on the seat to correctly wear the safety belt according to regulations.

    本发明公开了一种车内安全带检测装置,涉及汽车领域,包括位于安全带盒内部的检测部,其与安全带接触连接,用于检测安全带被外力拉出安全带盒的长度;与座椅内的压力传感器电性连接的控制器,控制器还与检测部电性连接,控制器内设定有阈值,且该阈值为安全带对人体保护时被拉出的长度;当人坐在汽车座椅上时,安全带在外力作用下拉动,并最终使公扣与母扣结合的过程中,控制器记录检测部检测到的安全带被拉出的长度,并与阈值进行比较;如果安全带被拉出的长度大于阈值,则说明安全带是正常佩戴;如果安全带被拉出的长度小于阈值,则说明座椅上的人并未正常佩戴,此时控制器可使车内的提示器发出提示音,提醒座椅上的人按规定正确佩戴安全带。
