A method for installing and fixing a fixed structure for installing a micro-motor

Abstract

The invention discloses a mounting and fixing method of a fixed structure for mounting a micro-motor. The method comprises the steps as follows: (a) a mounting hole of a micro-motor mounting plate is aligned at the mounting hole of an air conditioner shell; two elastic arms are extruded inwards to deform; the upper end of a movable limiting rod is clamped into a groove of a limiting arm; the movable limiting rod rotates around a hinge point by inward force of the limiting arm; and the upper end of the movable limiting rod is propped against the inner walls of the elastic arms provided with support rods; and (b) the two elastic arms pass through the mounting hole of the micro-motor mounting plate and the mounting hole of the air conditioner shell; the inward extrusion force to the two elastic arms is removed; the two elastic arms return towards two sides; two limiting blocks are clamped on the lower end surface of the air conditioner shell for limiting; and a pressing seat is pressed on the upper end surface of the micro-motor mounting plate. The mounting and fixing method has the advantages that (1) the mounting and fixing method is convenient to mount and dismantle and firm to connect, and damage to the micro-motor mounting plate and the air conditioner shell is avoided; and (2) deformation and fracture of the elastic arms due to overlarge pressure are avoided.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a method for installing and fixing a fixing structure for installing a micro-motor. Background technique [0002] In the air-conditioning system, there are often many micro-motors on the HVAC, such as mode micro-motors, internal and external circulation micro-motors, mixing damper micro-motors and so on. In the usual structure, the micro-motor is often installed directly on the HVAC shell, but under the current condition that the customer requires one piece to achieve multi-function, we need to add an auxiliary structure to the original manual HVAC, so that it can be realized Both manual and automatic effects coexist. But at the same time, it also brings about the problem of cost, because the addition of auxiliary structures often requires easy installation and disassembly, which undoubtedly requires our commonly used screw structure to achieve, and installat...

But at the same time, it also brings about the problem of cost, because the addition of auxiliary structures often requires easy installation and disassembly, which undoubtedly requires our commonly used screw structure to achieve, and installation and disassembly of the seal are also easy to cause damage to the micro-motor mounting plate and air-conditioning housing. damage
