Abstract

The invention provides a belt buckle device, which includes a frame, a locking plate, an inertial locking block, a release button and a locking spring, wherein the inertial locking block is an integrally formed belt shaft rotating part, and at the locking position, the A part of the load of the locking surface is transferred to act on the rotation shaft of the inertial locking block, and another part is transferred to the support member through the bearing member. According to the buckle device of the present invention, the inertia locking block is integrally formed, and the forming and assembling process is simple. And when loaded, a part of the load on the locking surface is transferred to act on the rotating shaft of the inertial locking block, and the other part is transferred to act on the supporting member on the frame through the bearing member, and the force direction of the rotating shaft and the supporting member both point to The axis of the rotating shaft ensures that the locking position is stable without deflection and the connection state of the lock tongue is stable.

Description

technical field [0001] The invention belongs to the technical field of automobile safety belts, in particular to a belt buckle device. Background technique [0002] As the basic protective device for protecting drivers and occupants during a car collision, the safety belt device is of self-evident importance. Wherein, the belt buckle device is an important part of the safety belt device. [0003] The Chinese patent with notification number CN100593984C discloses a buckle device which is provided with a locking plate which engages with a tongue-shaped plate inserted into the main body of the device and retains the tongue-shaped plate in the main body of the device, and a locking member that engages the locking plate and prevents movement of the locking plate to the release position, and has a body portion and a shaft supporting the body portion within the device body. The main body portion of the locking member is formed of sintered metal and the shaft is formed of metal an...
