Detailed Description

Embodiment is shown in fig. 1 to 5, the movement structure of the handle bar knob switch for the steering column combination switch of the automobile of the present invention comprises a rotating shaft 1 provided with a stationary contact 11, a movable contact 2 and a knob 3, wherein the movable contact 2 is located on the surface of the stationary contact 11, the movement structure further comprises a slider 4, a sliding rod 5 and a buckle cover 6, the sliding rod 5 is arranged on the front end surface of the slider 4, the front end of the sliding rod 5 is provided with a buckle 51, the buckle 51 is buckled on the end surface of the movable contact 2, the rotating shaft 1 is provided with a sliding groove 12 in the front of the stationary contact 11 along the axial direction, the bottom surface of the slider 4 is provided with a positioning rib 41, the outer arc surface is provided with a spiral groove 42, the slider 4 is arranged on the surface of the rotating shaft 1 and the positioning rib 41 is located in the sliding groove 12 of the rotating shaft 1, the inner ring side wall of the knob 3 is provided with a driving lug 31, the knob, the cover 6 is provided to the rear section of the rotary shaft 1 through a buckle 61 and covers the

movable contacts

2 and 11.

Preferably, the rotating shaft 1 is provided with guide grooves 13 on both sides of the sliding groove 12, the bottom surface of the sliding block 4 is provided with guide sliding blocks 43 on both sides of the positioning rib 41, and the guide sliding blocks 43 are located in the guide grooves 13. The guide sliding block is matched with the guide groove, so that the sliding block can move more smoothly on the surface of the rotating shaft, and clamping stagnation is avoided.

Preferably, two sides of the moving contact 2 are respectively provided with a protrusion 21, the side edges of the rotating shaft 1 at two sides of the stationary contact 11 are respectively provided with a long groove 14, and the protrusions 21 are located in the long grooves 14. The movable contact slides on the surface of the fixed contact under the driving of the sliding block and the sliding rod to realize the on-off of the contact, and the protrusion and the long groove play a role in positioning the movable contact, avoid the deviation of the movable contact in the sliding process, ensure the reliable contact or disconnection of the contact and play a role in guiding the sliding of the movable contact.

The movement structure changes the movement form of the movable contact of the knob switch, and improves the reliability of the electrical contact of the knob switch by adjusting the movement stroke of the movable contact. The moving structure utilizes the spiral groove of the outer arc surface of the sliding block, when the knob rotates, the sliding block is driven by the driving lug to move along the surface of the rotating shaft, and the sliding rod drives the moving contact to do linear motion, so that the moving form of the moving contact is changed from a rotating form to a linear form, the influence of the overall dimension and the rotating angle of the knob on the moving stroke of the moving contact is eliminated, the linear moving stroke of the moving contact can be changed by directly adjusting the thread pitch of the spiral groove, and the parametric adjustment of the moving stroke of the moving contact can be realized. Under the unfavorable condition that the external dimension and the rotation angle of the knob are reduced, the pitch of the spiral groove is properly increased to increase the linear motion stroke of the movable contact, and accordingly, the area of the fixed contact is increased, so that the reliability of the electrical contact of the knob switch is improved.

The moving structure solves the problem that the rotating angle is reduced to have adverse effect on the moving stroke of the moving contact due to the fact that the appearance of the knob switch is small and the switching function is increased, the moving form of the moving contact is changed by the aid of the spiral groove of the sliding block of the knob switch, the moving stroke of the moving contact is properly increased by increasing the thread pitch of the spiral groove, accordingly, the purpose of improving the electrical contact stability of the knob switch is achieved, and correct control of various lights and signals of an automobile is achieved.
