Problems solved by technology

However, the current locking mechanism of the balance weight-balance return button spring can only guarantee the safety requirement of 80g (g is the acceleration of gravity), while the acceleration generated by the impact force when the door is hit by the side can reach more than 90g, At this time, the balance return button spring will not be able to ensure that the handle body fits the door, and the door will open accidentally, causing an accident

Embodiment 1

[0024] A locking mechanism for preventing serial impact and inertial accidental door opening, comprising a base 1, a rotating shaft 2, a locking return torsion spring 3, an inertia locking block 4, a balance return torsion spring 5, a balance weight 6 and a handle body 7 ,Such as figure 1 As shown, the specific structure is:

[0025] There is a locking block groove on the base 1, and the locking block groove is as figure 1 As shown in middle A, the rotating shaft 2 is covered with a locking return torsion spring 3, and the two ends of the rotating shaft 2 pass through the two ends of the inertia locking block 4 respectively, and then are respectively embedded on the inner walls of the locking block groove on both sides. The two ends of the non-return torsion spring 3 are against the locking block groove and the inertia locking block 4 respectively;

[0026] Inertia lock block 4 as Figure 6 As shown, it is composed of a lock block 41, a lock wheel 42 and a lock claw 43, the...

Abstract

The invention relates to the field of handle bases for vehicles, in particular to a locking mechanism for preventing interlink impact inertia accidental vehicle door opening. The locking mechanism for preventing interlink impact inertia accidental vehicle door opening comprises a base (1) and a handle body (7) and is characterized by further comprising a rotating shaft (2), a locking return torsional spring (3), an inertia locking block (4), a balance return torsional spring (5) and a balance block (6), a locking block groove is formed in the base (1), and the two ends of the locking return torsional spring (3) abut against the locking block groove and the inertia locking block (4) respectively; the inertia locking block (4) is composed of a lock block (41), a lock wheel (42) and a lock claw (43); a balance block groove is further formed in the base (1), the two ends of the balance return torsional spring (5) abut against the balance block groove and the balance block (6) respectively, and the lock claw (43) right faces the balance block (6). The locking mechanism is simple in structure, convenient to install, high in adaptability, safe and reliable.

Description

technical field [0001] The invention relates to the field of handle bases for vehicles, in particular to a locking mechanism for preventing serial impact inertia and mistaken opening of doors. Background technique [0002] The car handle is used to lock and fix the car door and the car body. The handle is composed of a base, a handle body, a balance weight and a balance return button spring. The balance weight is fixed on the base with a balance return button spring, and the handle body is installed on the balance on the block. Under normal circumstances, under the action of the balance return button spring, the handle body has a movement tendency to fit the car door, which plays a role in fixing the handle and the car door. However, the current locking mechanism of the balance weight-balance return button spring can only guarantee the safety requirement of 80g (g is the acceleration of gravity), and the acceleration generated by the impact force when the door is hit by the...
