Description

Technical Field

[0001] The utility model relates to the field of vehicle door handle assemblies, in particular to a commercial vehicle door handle assembly. Background Art

[0002] The door handle assembly of commercial vehicles is an important part of the door assembly, which consists of an outside handle, a base, a rocker arm, a spring, etc. To ensure that the rebound force of the door handle does not fail due to long-term use, the spring stiffness of the door handle will be set to an interference fit.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN 218324403 U discloses a car door handle structure, a handle body, a handle cover is arranged on one side of the handle body, and a buffer pad is pasted on one side of the handle cover, an inner cavity is opened on one side inside the handle body, and a controller is installed on one side inside the inner cavity, a power box is installed on the other side inside the inner cavity, a middle cavity is opened at the middle position of the handle body, and a wire groove is opened at the top end inside the middle cavity, a heating plate is installed at the bottom end inside the middle cavity, and a heating wire is installed inside the heating plate; in this technical solution, when the handle body is restored after being pulled, the buffer pad plays a certain buffering role to reduce the reset vibration and noise.

[0004] With the above technical solution, although the buffer pad can play a certain role in buffering and vibration reduction, it will cause excessive opening force when using a door lock structure with a large rebound force. When the door handle is released to reset, the spring will bounce the door handle back to its original position, and the door handle will act directly on the buffer pad. Due to space reasons, the buffer pad cannot be made very thick, resulting in limited buffering and vibration reduction effect, and cannot meet the buffering and vibration reduction requirements when the opening force is large.

The connection between the driving part and the unlocking part is swingably connected to the base. The driving part is provided with a guide shaft, which extends into the guide groove on the arm body and can move along the guide groove. The unlocking part is provided with an unlocking piece.

[0014] Furthermore, the unlocking member is connected with a pull rod, and the pull rod is used to unlock the door lock.
