Description

Electronic gear shifting handle mounting structure and assembling method

Technical Field

The invention belongs to the technical field of automobile chassis, and particularly relates to an electronic gear shifting handle mounting structure and an assembling method.

Background

The common mounting mode of the electronic gear shifting handle is that a screw is tightened and the electronic gear shifting handle is inserted through an elastic piece.

The screw tightening installation mode has the advantages that the gear shifting handle is locked by the screw and is matched with the gear shifting rod without clearance, and the installation force of the handle to the gear shifting rod is usually small. The electronic gear shifting handle has the advantages that assembly is complicated and labor-saving, a special tool gun for tightening a screw is required, assembly cost is high, the modeling style of the handle is limited, the stop lever cannot be inclined at a large angle, otherwise, an installation tool has no operation space and can interfere with an auxiliary instrument (the handle is assembled on OEM running water), and if the electronic gear shifting handle and a mechanism are integrally supplied, an opening of the auxiliary instrument is required to be large, the electronic gear shifting handle must pass through, and the electronic gear shifting handle is not attractive.

The quick-insertion type mounting mode has the advantages that the assembly is simple, the handle is pressed down along the axis of the stop lever to be mounted in place, and the fixing by using a fastener is not needed. The defect is that in order to ensure that the handle has enough pulling-out force and a small fit clearance, the installation force of the handle is usually larger, the handle is assembled in place by means of tools such as a rubber hammer and the like, the electrical appliance plug connector inside the handle can be damaged with a larger probability in the assembly process, and meanwhile, the fit structure and the elastic part are extremely easy to damage or degrade after the handle is assembled and disassembled for several times.
