Abstract

The invention, which belongs to the technical field of the automobile safety accessories, discloses an alarm device of a safety belt. The alarm device comprises a retractor, a safety belt braided belt, a safety belt lock assembly and a safety belt reminder. The safety belt lock assembly includes a slot and a buckle. The safety belt reminder consists of a pressure sensor, a signal detection device, a controller and an alarm device; and the signal detection device is used for detecting the stretched length of the safety belt braided belt. A key tooth notch of a buckle profile part and a protruded or recessed elastic part inside the slot are complementary. With the alarm device, a behavior that a driver deceives an alarm device by selecting another buckle to buckle it into a seat based on universality of the traditional buckle or enabling a safety belt to pass through the space between the back of a passenger and the seat and to be inserted into a safety belt slot can be improved; a phenomenon that a slot is blocked because of entrance of impurities into the safety belt slot opening can be avoided; and accidental shedding of the safety buckle can be prevented. Moreover, the alarm device has advantages of simple and unique structure, uniqueness, low mutual unlocking rate, low manufacturing cost, high security, reliability, and practicability, and easy popularization and application.

Description

technical field [0001] The invention relates to the technical field of automobile safety accessories, and more specifically relates to a safety belt warning device. Background technique [0002] With the popularity and popularization of automobile products, people pay more and more attention to the safety factor of automobiles.
