Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 In the shown embodiment 1, a kind of car inner opening handle includes a handle base 1 and a handle 2, the handle base 1 fixes the inner handle bracelet on the door, and a micro switch 7 is arranged on the handle base 1, wherein the micro switch 7 The switch 7 adds the function of an electronic lock to the inner pull bracelet, and the micro switch 7 is provided with a shrapnel 701, the shrapnel 701 contacts the handle 2 and then transmits signals to control the opening and closing of the electronic lock, and the handle 2 is used to trigger the electronic lock and the mechanical lock. Lock, the handle 2 is rotatably connected to the handle base 1, a rotating shaft 3 is arranged between the handle 2 and the handle base 1, and a second return spring 4 that drives the handle 2 to rotate and reset is arranged outside the rotating shaft 3; in addition, the handle base 1 A limit plunger 5 is also arranged on the top, and the limit plun...

Embodiment 2

[0037] Embodiment 2 is a method for manufacturing an interior handle of an automobile, comprising the following steps:

[0038] Step 1: Firstly, the connecting inner part 204 is injection-molded through an injection mold, wherein the material used for injection molding of the connecting inner part 204 is PC / ABS+GF30;

[0039] Step 2: Rotate the connecting inner 204 and its injection mold by 180 degrees, install the injection mold used for the hand-held outer 203, and inject the hand-held outer 203. The injection molding material of the hand-held outer 203 is electroplating grade PC / ABS, and then hold the hand-held outer 203 Perform electroplating to complete the manufacture of the handle 2;

[0040] Step 3: Injection molding the handle base 1;

[0041] Step 4: Install the handle 2 on the handle base 1 to complete the manufacturing of the inner handle bracelet.

[0042] In this technical solution, since the wall thickness of the handle 2 itself is relatively large, double-sho...

The invention provides a car inner handle and its manufacturing method, which has an electro-mechanical double unlocking structure, and at the same time ensures that the mechanical lock will not be triggered under normal circumstances, and the inner handle is light and beautiful, and also satisfies the customer's requirements for strength and durability. test requirements.

Description

technical field [0001] The invention relates to automobile accessories, in particular to an automobile interior handle and a manufacturing method thereof. Background technique [0002] A traditional car door handle includes a handle base and a mechanical lock connected to the handle base, and the opening and closing of the car door is realized through the linkage between the handle base and the mechanical lock. Under normal circumstances, the handle that uses the mechanical lock linkage needs to integrate springs, pins, balance weights, inertia locks and other components. Due to the many moving parts of this kind of car door handle, the handle often gets stuck and shifts during use. , uneven gap and surface difference, etc., the comfort is greatly reduced, and the loss is large. The electronic switch system is an electronic product that controls the opening and closing of the mechanical switch through the operation of the circuit or chip, and completes the tasks of unlockin...
