Improved structure for automobile dome light switch

Abstract

The invention discloses an improved structure for an automobile dome light switch, and the structure comprises a pedestal (1) and a housing (2), which are clamped together to form a cavity. The structure is characterized in that a rotating seat (3) is disposed on the pedestal (1) in an embedded manner; an end face of the bottom of the rotating seat (3) is fixedly provided with a movable contact piece (4); a left combination piece (5) and a right combination piece (6) are located below the bottom end face of the rotating seat (3) and are pivoted to the internal bottom surface of the pedestal (1); the exterior of a supporting column (301) of the rotating seat (3) is sleeved by a reset spring (7); one end of the reset spring (7) abuts against a rotating block (8), and the other end of the reset spring (7) abuts against the bottom surface of the rotating seat (3); the rotating block (8) sleeves the supporting column (301) of the rotating seat (3); a press column (9) is located at the head part of the interior of the housing (1), and is engaged with the rotating block (8); the head of the press column (9) is provided with a spring (10) in a sleeve manner; one end of the spring (10) abuts against a step of the housing (2), and the other end of the spring (10) abuts against the head of the press column (9). According to the invention, the rotating seat (3) directly contacts with the movable contact piece (4), reduces the transmission process, and improves the stability and reliability of movement transmission.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an improved structure of an auto dome light switch. Background technique [0002] In recent years, with the rapid development of my country's economy, my country's automobile industry, especially the car industry, has been on the track of rapid development. Cars have gradually entered the homes of thousands of households and become a means of transportation that people often use in daily life. In order to meet the strong demand for cars, major automobile manufacturers continue to expand the production of cars and continue to launch various car brands. The development of the automobile industry has higher and higher requirements for the safety performance of cars. Therefore, cars need to be The performance of each component is tested, and only those that meet the relevant national safety standards are qualified products and are allowed to leave the factory for sale....

AI Technical Summary

Problems solved by technology

[0003] There are many lighting lamps on the car, all kinds of lighting lamps are controlled by the switch set in the driving position, among them, the dome lamp of the car is pressed according to the tooth shape of the lower end of the column, and the rotary block is rotated at a certain angle through the end tooth structure, and then the block is turned It is assembled with the rotating seat and the moving contact piece to form a whole linkage body, which is brought to the moving contact piece to rotate, and switches between the two combined pieces to realize its on-off function. This kind of switch connection is prone to connection fatigue and loss of control function
