An inertial lock mechanism for a vehicle door handle

Abstract

An inertia lock mechanism of a vehicle door handle comprises a base and a door handle body. A handle hook base and a hook body located at the tail end of the handle hook base are arranged at one end of the door handle body, an inertia lock block is arranged outside one side of the handle hook base, an oblique plane is arranged at the tail end of the hook body, and a locking groove is formed in the oblique plane in a concaved mode. The inertia lock block comprises a body, a first lug, a second lug and a third lug, the tail end of the first lug is close to the handle hook base, the tail end of the third lug is away from the handle hook base, the second lug is located between the inner side of the first lug and the inner side of the second lug, the tail end of the second lug is close to the hook body and can stretch into the locking groove, the body is mounted on the base through a pin shaft in a rotating mode, the pin shaft is sleeved with a torsional spring, and the two ends of the torsional spring support the outside of the first lug and the inner side of the base respectively. The inertia lock mechanism of the vehicle door handle has the advantages that by the adoption of the structure, it can be guaranteed that a vehicle door cannot be opened when the vehicle is subjected to lateral impact, the safety performance of the vehicle is improved, and the structure is simple, mounting is convenient, and the adaptability is high.

Description

technical field [0001] The invention relates to an inertia lock mechanism of a vehicle door handle. Background technique [0002] The vehicle door handle is used to lock and fix the vehicle door and the vehicle body. The vehicle door handle includes a base fixed on the vehicle door, a door handle body located outside the base and outside the vehicle door, and a balance weight located inside the base. One end of the door handle body is provided with a handle hook seat pierced on the base, and the end of the handle hook seat protrudes from a hook body located on the inner side of the base, and the balance weight is fixed on the on the base. Under normal circumstances, under the interaction of the balance weight and the balance return button spring, the door handle body has a movement tendency to fit the car door, which plays a role in fixing the door handle body and the car door so that the car door will not be opened. , When the door is hit sideways, the balance return butt...
