2 to 6, the silicon button module for a vehicle according to an embodiment of the present invention is located on the PCB 100 and the PCB 100 provided with the switch 105 and the LED 106, and the PCB ( 100) is fixed and coupled to the switch 105 and presses the switch 105, the silicon button unit 110 with buttons 112 representing the LED 106 to the outside, and the buttons 112 so that the buttons 112 are coupled It includes a button body 130 having a plurality of insert holders 131 provided in response to.

The PCB 100 is provided with a button fixing hole 101 in which a lower portion of the silicon button portion 110 is inserted and coupled, and the silicon button portion 110 is provided with a panel-shaped button body 111 and is fixed with a button. An insertion protrusion 113 inserted into and coupled to the hole 101 is provided under the button body 111.

The silicone button module for a vehicle according to an embodiment of the present invention may be fixed by being coupled to and fixed to the PCB 100 by the silicone button unit 110, and by inserting and fixing buttons 112 in the button body 130. The assembly module is formed.

The silicon button module has an assembly module structure of the PCB 100, the silicon button unit 110, and the button body 130, and as the parts are simplified compared to the existing ones, the button unit is assembled with the PCB 100 and the buttons. It is firmly fixed in position between the body 130.

In one embodiment of the present invention, the existing button panel is omitted to eliminate the factor of material cost increase, the number of work of the assembly screw is reduced as the number of parts is reduced, and the leakage and silicon button tearing are improved by the solid coupling structure, and the button The size can be reduced.

Referring to FIG. 5, the button 112 of the silicon button unit 110 has a columnar shape with a rectangular cross section upright on the button body 111. The button 112 is integrally formed on the button body 111. A switch accommodation unit 115 in which the switch 105 and the LED 106 are accommodated is provided under the button 112.

The switch receiving portion 115 is located on the lower PCB 100 in the upper and lower cross-sectional shape of the button 112, and accommodates the switch 105 and the LED 106. The switch receiving portion 115 may be provided with a right-angled jaw 116 having a right-angled shape from top to bottom. The switch 105 contacts the upper surface of the switch receiving portion 115.

The button 112 has a square shape, and the insert holder 131 may have a width of about 6 mm. The button 112 is inserted into the PCB 100 in a state where the button body 111 is disposed on the PCB 100 and is inserted into the button body 130 in a fixed state to be exposed to be pressed outward.

Accordingly, since the button 112 is sufficiently supported by the PCB 100, a structure such as a conventional PCB 100 panel is not required, and the lower portion of the button body 130 is supported on the button body 111, thereby making the PCB It is a structure that is fixed by pressing to the (100) side. The button 112 can be designed to be changed to a small size due to structural stability, and can be stably exposed and disposed on the button body 130.

The connecting member 117 is a thin panel shape connecting the button 112 and the button body 111, and is made of silicone to provide elasticity.

When the button 112 is pressed toward the button body 111, the connecting member 117 provides elastic up and down elasticity of the button 112 by elasticity, and the button body 111 and the button at the bottom of the button 112. Since (112) is connected, it prevents cracking or tearing of the upper part of the button due to frequent pressing of the button.

5 and 6, a plurality of flow prevention ribs 132 supported on the outer wall portion of the button 112 are formed on the inner wall portion of the insert holder 131 in a linear shape along the vertical direction, and a plurality of flow The prevention rib 132 supports the outer wall portion of the button 112 to guide vertical movement, thereby preventing the entire friction between the button 112 and the insert holder 131.

This flow prevention rib 132, when the button 112 is moved up and down in the insert holder 131 of the button body 130, reduces friction to make the up and down movement of the button 112 smooth, The phenomenon that it does not return again while entering the interior of the insert holder 131 is prevented.

The plurality of flow prevention ribs 132 may be disposed on all sides of the insert holder 131 corresponding to the shape of the button 112 to be in contact with the slope portion of the button 112.

3 to 5, the button body 111 is in close contact with the PCB 100, and the insertion protrusion 113 penetrates the button fixing hole 101 of the PCB 100, while the button fixing hole 101 Light leakage through may be blocked.

When the boss 133 of the button body 130 is screwed to the PCB 100, and the insert holder 131 presses the upper surface of the silicon button portion 110, the button body 111 with the insertion protrusion 113 Can be closely adhered to the button fixing hole 101 without a gap, and light leakage is blocked through the insertion protrusion 113 and the button fixing hole 101.

An assembly guide 120 for accommodating the button portion and the insert holder 131 may be provided on an upper surface portion of the button body 111. The assembly guide 120 fixes the position of the insert holder 131 in one region on the button body 111 while supporting the insert holder 131 from both sides.

7 is a cross-sectional view of the half-moon shaped button and the circular knob and half-moon shaped button of FIG. 2.

1 and 7, one of the buttons 112 has a half moon shape, and an embodiment of the present invention penetrates the button body 130 adjacent to the half moon shape button 125 to the outside. It may further include a circular knob 135 is disposed. The half moon-shaped button 125 may provide illumination to the circular knob 135.

The half-moon-shaped button 125 receives the light of the LED 106 from the bottom and exposes it to the top, and the circular knob 135 provides the light of the LED 106 at the bottom through the half-moon-shaped button 125. do. Accordingly, it is possible to add convenience to the operation of the circular knob 135.

8 is a cross-sectional view of a button assembly according to another embodiment of the present invention.

Referring to FIG. 8, the assembly guide 120 according to another embodiment may have a tapered shape of an inner wall portion so that the insert holder 131 is easily accommodated. The tapered shape of the assembly guide 120 is a structure in which the insert holder 131 can be guided more easily onto the button body 111 than the straight shape. The tapered shape of the assembly guide 120 is represented by an inclined surface portion inside.

A vehicle according to an embodiment of the present invention is one in which the above-mentioned silicone button module for vehicles is installed. Such a vehicle can omit the button panel, which was a factor in the increase of the existing material cost, reduce the work of assembly screws, improve tearing and tearing of the silicone button, and reduce the button size to provide a compact and simple internal environment.
