[0025] The mode switch provided by the embodiment of the utility model can be used to control functions such as air volume adjustment and volume adjustment of the air conditioner on the vehicle. Figures 1 to 3As shown, it includes a lower seat 1, an upper cover 2, a circuit board module 3, a knob 4 and a rotary encoder 5; the lower seat 1 is fixed to the bottom end of the upper cover 2, and a wire hole 14 is provided on the lower seat 1, and the wire hole 14 is provided to allow the wires connecting the circuit board module 3 and the vehicle control circuit to pass through, the knob 4 is covered on the outside of the upper end of the upper cover 2, and the rotating shaft 51 of the rotary encoder 5 is fixedly connected to the knob 4; a threaded through hole is provided on the upper cover 2, and an external threaded portion 52 surrounding the rotating shaft 51 is provided on the rotary encoder 5, and the external threaded portion 52 is screwed to the threaded through hole, and the circuit board module 3 is fixedly connected to the rotary encoder 5. The structure of this embodiment has a reasonable structural design and is easy to assemble.

This facilitates assembly and is conducive to improving assembly production efficiency. During installation and use, the knob 4 is rotated to drive the rotating shaft 51 of the rotary encoder 5 to rotate, thereby outputting the output signal to the vehicle control circuit.

[0026] Preferably, the rotary encoder model is EC11H 5FE12A12D10F4 (M2.5), which outputs the phase difference according to the left and right rotation signals, and the waveform is as follows: Figure 4 As shown in .

[0027] like Figure 2 and Figure 3 As shown, the circuit board module 3 includes an upper circuit board 31 and a lower circuit board 32 spaced apart from each other. The upper circuit board 31 and the lower circuit board 32 are fixedly connected via pins 33, and the pins 33 electrically connect the upper circuit board 31 and the lower circuit board 32. The lower circuit board 32 is fixedly connected to the pins of the rotary encoder 5. Lamp beads 34 are provided on the upper circuit board 31. The upper cover 2 is made of transparent material. A light-transmitting portion is provided on the knob 4. When in use, the light emitted by the lamp beads 34 passes through the upper cover 2 and the light-transmitting portion to emit, thereby achieving a light indication effect and increasing the aesthetics.

[0028] Further, if Figure 2 As shown, an outwardly protruding annular boss 21 is provided on the outer peripheral wall of the upper cover 2. The annular boss 21 is located in the gap between the knob 4 and the lower seat 1. The light is guided out from the side of the mode switch through the annular boss 21, thereby forming a halo around the mode switch and enhancing the aesthetics of the switch.

[0029] An annular ridge 22 is provided on the upper cover 2 around the threaded through-hole, and the upper circuit board 31 is arranged around the annular ridge 22 . Such an arrangement can limit the upper circuit board 31 through the annular ridge 22 .

Furthermore, a recess is provided at the upper end of the upper cover 2, into which the knob cap 6 is fixed. A corresponding light-transmitting area is also provided on the knob cap 6 to allow light emitted by the lamp beads 34 to pass through. The light-transmitting area is preferably configured in the shape of a character.

[0031] In order to facilitate the control of the mode switch, the side wall of the knob 4 is provided with a concave-convex texture, which can increase the surface roughness of the knob 4, thereby allowing the fingers to grip better and facilitating the rotation control of the knob 4.

When installing the mode switch, the locking nut 8 is used to cooperate with the mounting tube portion 12 for locking.

[0033] See Figure 2 As shown, a fixing buckle 13 is provided inside the lower end of the lower seat 1. The fixing buckle 13 is arranged close to the wire hole 14. When in use, the wire passes through the wire hole 14, and a cable tie can be used to tighten the wire and the fixing buckle 13 to prevent the connection between the wire and the circuit board module 3 from failing when the wire is pulled by external force.

[0034] The lower end of the upper cover 2 is provided with an opening for installing the circuit board module 3 and the rotary encoder 5. With this arrangement, when assembling the mode switch, the circuit board module 3 and the rotary encoder 5 are first connected into a whole, and then the whole is installed into the interior of the upper cover 2 through the opening, and the external threaded portion 52 is screwed into the threaded through-hole.
