Knob-type gating switch balancing device for automobile electrical appliances

Abstract

The invention discloses a knob-type gating switch balancing device for automobile electrical appliances. The device comprises a switch upper cover and a switch lower cover, and is characterized in that: the switch upper cover is arranged on a gating switch balancing body by an upper positioning column and a lower positioning column, and is fixed in an upper cover fixing groove by an upper cover fixing clip; the gating switch balancing body is arranged in the switch lower cover; and limit structures are formed between the upper cover fixing clip of the switch upper cover and the upper cover fixing groove of the gating switch balancing body, between the limit groove of the gating switch balancing body and the internal limit column of the switch lower cover, and between the stop position of an elastic arm and the external limit column of the switch lower cover. The plurality of structures of a traditional knob switch are integrated together, so that the knob-type gating switch balancing device is high in integration level and reliable in performance, and a mould is simple and easy to realize. The knob-type gating switch balancing device has the advantages that: shaking quantity is greatly reduced and operating force is uniform in the operating process in circular motion; and the knob-type gating switch balancing device has clear gears, a high integration level, good hand feel, high practicality, low cost and high performance, and is easy to machine, quick in installation, simple and reliable.

Description

technical field [0001] The invention relates to automobile equipment, in particular to a knob-type gating switch balancing device for automobile electric appliances. Background technique [0002] At present, all automobiles (especially off-road vehicles) at home and abroad are equipped with a large number of automotive electrical knob-type strobe switches, such as air-conditioning control switches and four-wheel drive switches. With the development of technology and the improvement of people's quality of life, today's car users have higher requirements for the clear positioning and smooth operation of such switches. The world's major car manufacturers have invested a lot of money and technical strength in research and development. A new type of knob-type strobe switch for automotive electrical appliances, but the technical structure is complex and the cost is high.

Problems solved by technology

With the development of technology and the improvement of people's quality of life, today's car users have higher requirements for the clear positioning and smooth operation of such switches. The world's major car manufacturers have invested a lot of money and technical strength in research and development. A new type of knob-type strobe switch for automotive electrical appliances, but the technical structure is complex and the cost is high

[0003] The traditional knob-type strobe switch generally adopts the structure of metal shrapnel, metal swing arm, steel wire spring + steel ball. The disadvantages of this structure are high cost, high processing precision, and jerky hand feeling.

When the diameter of the knob-type strobe switch for automotive electrical appliances is greater than 30 mm, it is difficult to manufacture to meet high positioning accuracy and control comfort, and there are also the following problems: 1. When the knob-type strobe switch performs circular motion The shaking will be relatively large, and it is very difficult to control the shaking; 2. When the knob switch makes a circular motion, the operating force is uneven; 3. The selection gear is not clear
