Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a slide switch for a vehicle, and particularly to a slide switch for a vehicle with an improved sliding support structure for a slider.

[Prior Art] Vehicles such as passenger cars are equipped with various control switches for controlling in-vehicle electrical equipment. For example, a slide switch that controls the heater in stages is used as a means to adjust the temperature inside the car. There is. Slide switch 12 like this
conventionally has an appearance as shown in FIG.
The slider 18 is disposed so as to be movable along the longitudinal direction of the slit 16 formed in the hole a.
The mounting housing 14 has a guide groove 20 extending in the longitudinal direction.

The slider 18 is provided with an operating knob 22 at one end, and a temperature adjustment link 24 is pivotally attached to the other end by a pin 26. Further, a guide piece 28 is provided at an intermediate portion between the operating knob 22 and the pin 26, and this guide piece 28 is mounted in the guide groove 20 under pressure by a spring (not shown).

With the above configuration, the backlash of the slider 18 in the front and back direction is absorbed by the pressure inside the guide groove 20, and the play in the vertical direction is absorbed between the bottom surface of the guide groove 20 and the guide piece 28, and on the top and bottom surfaces of the slit 16. It was regulated by the range of the gap that occurred between the two. By sliding the operating knob 22 in the direction of arrow A, the slider 18 also slides along the guide groove 20, and the temperature adjustment link 24
is rotated in the direction of arrow B about a fulcrum (not shown) by a pin 26 and displaces the contact of the variable resistor 30, thereby controlling the current flowing through the heater and adjusting the temperature of the heater.

[Problems to be solved by the invention] Conventional problems However, in the conventional slide switch, the gap between the guide groove and the guide piece and between the slider and the vertical width of the slit prevents the slider from sliding. There was a problem in that shaking and rattling occurred when the switch was operated.

Purpose of the invention This invention was made in order to solve these problems, and its purpose is to provide a slide switch for vehicles with excellent operability by eliminating shaking and rattling when operating the slide switch for vehicles. do.

[Means for Solving the Problems] The present invention is a slide switch for a vehicle that is operated by a passenger inside a vehicle, and includes a slit formed through the front wall in the longitudinal direction, and a slit located above the inside of the slit. a mounting housing having a concave guide groove formed in the longitudinal direction corresponding to the slit; An operating knob is provided on the front end,
An adjustment link is pivotally attached to the rear end, and between both ends there is a convex guide piece that protrudes upward from the inside of the front wall and is slidable to fit into the guide groove of the mounting housing, and has a slit. and a slider disposed so as to be movable along the guide groove, and a moderation spring that is interposed between the guide groove of the mounting housing and the guide piece of the slider and biases the guide piece against the guide groove, A stopper is formed on the slider to protrude downward and can slide integrally with the slider in a sealed state on the inner surface of the front wall located below the slit of the mounting housing, and prevents the slider and the mounting housing from moving when the knob is operated. It is characterized by preventing backlash that occurs between the two.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 is a schematic side view of the vehicle slide switch according to the present invention when it is installed. In the same figure,
The vehicle slide switch 32 is, for example, a temperature control switch, and includes a mounting housing 34 and a slider 36. The mounting housing 34 also serves as a housing for mounting a mode change switch, etc., and so-called vehicle heat control switches are housed together in the mounting housing 34. An elongated slit 40 is bored in the front wall 38 of the mounting housing 34, and a guide groove 42 with a rectangular cross section is provided inside the front wall 38 along the longitudinal direction of the slit 40.

The slider 36 is disposed so as to be movable along the longitudinal direction of the slit 40. That is, as shown in FIGS. 2A and 2B, this slider 36 has a rectangular guide piece 50 protruding from the middle of both ends of a flat board, and a pin mounting hole 47 is bored at one end. has been done. The guide piece 50 is provided with a rectangular spring mounting groove 49, into which a moderation spring 52, which will be described later, is mounted as shown by a chain line. Further, a temperature adjustment link 46, which will be described later, is pivotally attached to the pin attachment hole 47 by a pin 48.

An operating knob 44 is provided at one end of the slider 36 as shown in FIG.
The temperature adjustment link 46 rotates through the heater, displacing the contact of a sliding resistor (not shown), and adjusting the heater temperature to a desired temperature. At this time, the guide piece 50
is slidably fitted into the guide groove 42, and a moderation spring 52 is installed between the front wall of the housing 34 and the guide piece 50, and the guide piece 50 responds to the biasing force of the moderation spring 52. Therefore, it slides while being pressed against one side of the guide groove 42.

As described above, the feature of the present invention is that the stopper 54 protrudes from the slide 36, and the stopper 54 is slidably brought into close contact with the front wall 38 of the mounting housing 34. That is, in the embodiment, as shown in FIGS. 1 and 2, a flat plate-shaped stopper 54 is vertically provided in the middle of the slider 36 near the side opposite to the guide piece 50, and one surface of this stopper 54 is connected to the housing 34. Front wall 38
Closed inside.

Therefore, according to this embodiment, the guide piece 50 slides while being constantly pressed against one side wall of the guide groove 42 by the biasing pressure of the moderation spring 52.
Since the stopper 54 slides in close contact with the front wall 38 of the housing 34, the slider 36 can move smoothly without play.

In the embodiment described above, the moderation spring 52 is installed between the guide piece 50 and the front wall 38, but the moderation spring 52 is not limited to this. A moderation spring 52 may be installed between the guide pieces 50. By doing so, the guide piece 50 and the stopper 54 are pressed against the front wall 38 by the biasing pressure of the moderation spring 52, and wobbling and rattling when the slider 36 moves can be reliably eliminated.

[Effects of the invention] As explained above, this invention has a stopper protruding from the slider, and this stopper is slidably brought into close contact with the front wall of the mounting housing, thereby reducing the sliding part between the slider and the mounting housing. There is no backlash between the slider and the slider, and unpleasant sensations such as shaking when operating the slider can be avoided and a smooth feel can be enjoyed.
