Description

Knob type strobe switch balance device for automobile electrical appliances

technical field

The invention relates to automobile equipment, in particular to a knob-type gating switch balancing device for automobile electric appliances.

Background technique

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.

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

Contents of the invention

The object of the present invention is to provide a knob-type strobe switch balance for automobile electrical appliances with greatly reduced shaking when operating in a circular motion, uniform operating force, clear gear positions, high integration, easy processing, good hand feeling, simple reliability, and high performance. device.

The purpose of the present invention is achieved like this:

A knob-type strobe switch balance device for automobile electrical appliances, including a switch upper cover and a switch lower cover, gears are arranged on the outer surface of the switch upper cover, and the wings on both sides of the outer wall of the switch lower cover are processed with screws. The installation hole where the lower cover is fixed on the car body is characterized by a gating switch balance body assembled in the lower switch cover, an upper positioning post is processed in the middle of the lower part of the switch upper cover, and an upper positioning post is provided on the upper positioning post. The column hole is evenly processed at the bottom of the switch cover and around the upper positioning column, with a number of upper cover fixing cards arranged axially at intervals; in the middle of the upper part of the circular gating switch balance body, there are holes that can be inserted into the upper The lower positioning post in the hole of the upper positioning post on the positioning post is processed on the inner wall of the upper part of the balance body of the strobe switch. There is an upper cover fixing slot for the upper cover fixing card of the switch cover to be inserted and positioned. Two " The L”-shaped elastic arm is composed of a cross arm and a vertical arm. The bottom ends of the two cross arms are symmetrically fixed on the outer wall of the balance body of the strobe switch. There are arc-shaped stop positions on the outer walls of the two cross arms. There are arc-shaped positioning curved surfaces on the top of the two suspended vertical arms, and two symmetrical limit grooves are processed on the inner wall of the lower part of the balance body of the strobe switch; The positioning groove at the top of the vertical arm of the arm is matched with the positioning curved surface. A circuit board is installed in the middle of the bottom plate of the switch lower cover and the inner side of the bottom plate of the switch lower cover is processed to pass through the circuit board and limit the limit groove. The inner limiting column of the switch lower cover is processed with an outer limiting column capable of limiting the stop position on the outer wall of the cross arm on the outer side of the bottom plate top of the switch lower cover.

The cross-sectional shapes of the upper positioning post hole and the lower positioning post are both semicircular for positioning and preventing relative slippage.

The outer wall of the upper cover of the switch is processed with anti-slip lines to prevent slipping.

The invention is composed of a switch upper cover, a gating switch balance body and a switch lower cover, between the upper cover fixing card of the switch upper cover and the upper cover fixing groove of the gating switch balancing body, the limit groove of the gating switch balancing body and the A limit structure is formed between the inner limit posts of the switch lower cover, the stop position of the elastic arm of the balance body of the strobe switch and the outer limit posts of the switch lower cover, so that the knob-type strobe switch is in operation. Shaking and overshifting will not occur. The positioning curved surface at the top of the vertical arm of the elastic arm cooperates with the three positioning grooves on the inner wall of the lower cover of the switch to move, so that the knob-type strobe switch can get a good feel, and the elastic arm can provide sufficient and suitable balanced damping force during the movement , so that the control force of the knob-type strobe switch is uniform and easy to control. The switch upper cover is installed on the balance body of the strobe switch through the upper positioning post and the lower positioning post, and is fixed in the four upper cover fixing slots through four upper cover fixing clips, which not only plays a fixed role, but also reduces the need for switching on the switch. Axial wobble when the cover is rotated.

Working principle: By rotating the upper cover of the switch, the upper cover of the switch will drive the balance body of the gating switch to rotate together through the upper positioning post and the lower positioning post to realize the gating gear function. During the rotation movement of the upper cover of the switch and the balance body of the strobe switch, when the rotation reaches the initial position, the stop position is limited by the outer limit column; when the rotation reaches the end position, the limit slot is limited by the inner limit column. Limit, so that the circular movement of the switch is effectively stopped, and no over-shift phenomenon will occur.

The invention integrates many structures of the traditional knob switch, has high integration degree, reliable performance, simple and easy realization of the mold, adopts nylon material, low cost, easy control parameters and good lubricating properties. These advantages are not available in traditional rotary switches. The present invention can adjust the length of the two elastic arms according to the actual size of the upper cover of the switch, and the elastic arms can provide sufficient and suitable balanced damping force. As a result, when the switch is operated in a circular motion, the shaking amount is greatly reduced, and the operating force is uniform and smooth. The gears are clear and the control force meets the design requirements. The present invention is designed as a symmetrical structure, and can be installed in two directions of 0 degree or 180 degree during assembly, and is simple, reliable and practical.

Therefore, the present invention has the advantages of greatly reduced shaking during circular motion operation, uniform operating force and clear gear positions, high integration, easy processing, quick installation, good hand feeling, simple and reliable, strong practicability, low cost, and high performance. .
