Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a control switch rotation structure and control switch. Background Technology

[0002] In traditional rotary control switch structures, the rotational engagement between the steering bracket and the housing typically employs a rigid fit between a shaft and a slot, where the shaft is embedded in a slot or guide rail within the housing to achieve both limiting and rotational movement. While this design provides basic structural support, it suffers from several significant drawbacks: the shaft and slot are in surface or line contact, resulting in a large friction area and consequently high resistance during rotation. This necessitates greater operational force from the user and can lead to fatigue over extended periods. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a control switch rotation structure and control switch.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a control switch rotation structure, comprising a housing and a handle assembly rotatably disposed on the housing, the handle assembly being connected to a steering bracket, the steering bracket rotating synchronously with the handle assembly, rotating grooves being provided on both sides of the steering bracket, and a spherical support structure integrally formed within the rotating groove; a protrusion is provided on the inner wall of the housing corresponding to the position of the rotating groove, the protrusion extending into the rotating groove, and the end of the protrusion contacting and engaging with the end of the spherical support structure; the diameter of the spherical support structure is smaller than the diameter of the rotating groove, and the spherical support structure is formed at the center position of the rotating groove.

[0005] As a preferred embodiment of this utility model, the spherical support structure is a boss with a spherical contact portion; the top of the spherical contact portion forms a surface contact or line contact with the lower end face of the boss, and the bottom is transitionally connected to the bottom surface of the rotating groove.

[0007] As a preferred embodiment of this utility model, the spherical support structure is made of wear-resistant material and has a radius ranging from 0.5 to 1 mm.

[0008] A control switch further includes: a circuit board disposed within a housing; and a contact assembly linked to a steering bracket, wherein the steering bracket drives the contact assembly to slide relative to the circuit board.

[0009] As a preferred technical solution of this utility model, the housing includes an upper cover and a bottom cover, and a track body is provided between the upper cover and the bottom cover; the handle assembly includes a handle part and a connecting part, and a compression spring and a top pin are provided in the connecting part. One end of the top pin extends out of the connecting part and cooperates with the rotation track of the track body, and the other end abuts against the compression spring.

[0010] As a preferred embodiment of this utility model, the steering bracket includes a frame portion and a swivel plate portion hinged to the housing. The connecting portion passes through the frame portion and is provided with a lever. The lever rotates synchronously with the connecting portion. A through groove is provided between the frame portion and the swivel plate portion. One end of the lever passes through the through groove and connects to the contact assembly. The contact assembly includes a limiting seat disposed in the bottom cover and an upper contact piece disposed in the swivel plate portion.

The steering bracket 3 rotates synchronously with the handle assembly 2. Rotation grooves 4 are provided on both sides of the steering bracket 3, and a spherical support structure is integrally formed in the rotation groove 4.
