Field of technology

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device for entering a switch by operating a swingable operation knob, and more particularly to a waterproof switch device that prevents water from entering a case.

Prior art

In the arm rest of the door of a vehicle, the console of a center, etc., the switch apparatus used for the window opening / closing apparatus (power window apparatus) of an automobile is arrange | positioned. As disclosed in Patent Literatures 1 and 2 described below, a switch, a circuit board, and the like are housed in a case, and the switch device communicates with the case by opening up and down on the case upper surface. This is provided. In addition, the cylinder is provided with an operation knob so as to swing back and forth so as to cover the opening of the upper part of the cylinder, and the operation rod is connected to the operation knob which extends into the case through the opening of the cylinder and transmits the movement of the operation knob to the switch. It is. Then, by swinging the operation knob back and forth, the movement is transmitted by the operation rod, and the switch is turned on or off.

In general, a cover is attached to the switch device so as to cover the upper surface of the case, and an operation knob is operatively exposed from the opening provided in the cover. For this reason, even if some rainwater hits a cover in rainy weather etc., the said rainwater never enters the case of a switch device. However, when a large amount of beverage or the like (hereinafter referred to as "water") is placed on the cover, the water flows through the gap between the opening of the cover and the operation knob and flows down to the upper surface of the case, and flows to the tube side and the like. . And the water which flowed to the cylinder side raises the clearance gap of an operation knob and a cylinder by the force, penetrates into the case through the opening of a cylinder, and causes corrosion and a short circuit in a switch or a circuit board.

As a countermeasure for preventing ingress of water as described above, Patent Literature 3 described below forms a water trapping groove before and after the barrel of the case upper surface of the switch device, and inclines the bottom of the groove toward the front of the case or at the center portion thereof. Forming into a mountain shape having a water fountain, it is disclosed to form a drain hole penetrating the deepest portion of the water trapping groove on the front or side surface of the case. Patent Documents 1 and 2 disclose no countermeasures against water intrusion.

Patent Document 1: Japanese Patent Application Laid-Open No. 8-180755

Patent Document 2: Japanese Patent Laid-Open No. 5-314864

Patent Document 3: Patent No. 3111221

However, in the technique of Patent Document 3 described above, water flowing down the upper surface of the case through the gap between the cover (Finisher in Patent Document 3) and the operation knob flows into the water capturing groove and is trapped on the slope of the bottom of the groove. Therefore, it collects at the deepest part of the front and discharges it from the drain on the side of the case which is relatively smaller than the width or depth of the water trapping groove. Therefore, when the amount of water is large, even if water flows into the water trap groove, There is a possibility that the water overflows from the water trapping groove, flows to the cylinder side, raises the gap between the operation knob and the cylinder, and penetrates into the case through the opening of the cylinder.

Then, an object of this invention is to provide the switch apparatus which can prevent water from invading into a case through the opening of a cylinder from the outside.

In the present invention, a switch, a case in which the switch is housed therein, a cylinder provided on an upper surface of the case, open up and down to communicate with the inside of the case, and swing back and forth to cover the opening of the cylinder A switch device having a control knob provided so as to extend through the opening of the barrel from the operation knob into the case, and to transmit a movement of the operation knob to the switch, between the case upper surface and the end of the operation knob. The guide part which inclines in the left-right direction and flows water to the side of a case is provided.

In the above, the guide portion may be inclined downward toward both the left direction and the right direction, and may be inclined downward only toward either one.

As described above, even if water flows from the outside to the end of the operation knob on the upper side of the case, the water often flows along the guide portion and is discharged to the left and right sides of the case. It can be prevented from rising and intruding into the case from the opening of the cylinder. In particular, in a switch device used for a power window device or the like, the width in the left and right directions of the case is generally shorter than the width in the front and rear directions, and the distance from the barrel to the left and right sides of the case is shorter than the distance from the front and back sides. As the water flows to the left and right sides of the case along the guide portion, water can be quickly discharged from the case to the outside, and the intrusion of water into the case can be prevented more reliably.

Moreover, in one Embodiment of this invention, the guide part is made into the mountain shape which inclines downwardly toward both left and right directions.

In this way, the water flows down in both the right and left directions along the guide portion, so that the water can be quickly separated from the upper opening of the barrel and the lower end of the operation knob, thereby further preventing the ingress of water into the case.

Moreover, in one Embodiment of this invention, one edge part is located in the barrel side rather than the edge part of an operation knob among the edge parts before and behind the guide part, and the other end part is located on the opposite side to the passage | pass side than the edge part of an operation knob. have.

In this case, since the guide portion is located directly below the end of the operation knob, water flowing through the end portion is dropped directly on the guide portion, and immediately flows along the guide portion along the guide portion, making it difficult to flow to the cylinder side. It is possible to prevent further intrusion of water into the case.

Moreover, in one Embodiment of this invention, the edge part of the front and back of the guide part is provided adjacent to the side surface of a cylinder, and provides the flange which protrudes toward the other end part of a guide part above the guide part of the said side surface. Doing.

In this way, the water can flow to the side of the case along with the guide section without remaining water between the guide section and the tub, and the water will rise even if the water on the guide portion collides with the side surface of the tub. Passage through the gap between the operation knob and the cylinder to the upper opening of the cylinder can be prevented by the flange, which further prevents water from entering the case.

Moreover, in one Embodiment of this invention, the groove | channel by which the edge part was opened so that the guide part may be adjacent to the guide part and may pass to the left and right side surface of the case is provided in the vicinity of the guide part.

In this way, even if water flows in a direction other than the guide direction of the guide part, that is, in a direction other than the direction in which the inclination is lowered due to the force dropped on the guide part, water does not enter the groove in the direction and does not return to the guide part. Thus, the water can pass through the open end of the groove and can be discharged to the left and right sides of the case, further preventing the ingress of water into the case.

Moreover, in one Embodiment of this invention, the case upper surface of the guide part vicinity is inclined downward toward the side surface of case left and right.

In this way, the water which flowed from the guide part to the case upper surface of the vicinity of the guide part flows along the inclination of the case upper surface, without making it stay in the case upper surface, and it is easy to discharge to the side of a case, The intrusion of water into the inside can be further prevented.

Moreover, in one Embodiment of this invention, the recessed part is provided in the vicinity of the edge part of the operation knob of a case, and the said guide part is provided in the said recessed part.

In this way, the installation space of the guide portion can be secured between the upper surface of the case and the end of the operation knob without raising the attachment position of the operation knob to the upper side of the case. Therefore, the height is suppressed and the switch device can be miniaturized. It becomes possible.

According to the present invention, even if water flows from the outside to the end of the operation knob on the upper surface of the case, since the water flows along the guide part and is discharged to the left and right sides of the case, the water raises the gap between the operation knob and the barrel. This prevents the intrusion into the case from the opening of the cylinder.

The bottom 13b of the groove 13 is located at the same height as the uppermost part of the case upper surface 1u 'as shown in FIG.

In the switch device 100 having the above-described structure, the rainwater penetrating from the window that has been forgotten to close or the drink accidentally lifted up in the vehicle (hereinafter referred to as “water”) are the cover 20 and the operation knob 6. When the water flows up to), the water enters into the recessed portion 20d from the opening 20c of the cover 20, as indicated by the arrow in Fig. 6, and the gap between the cover 20 and the operation knob 6 is obtained. It flows down through 18. Then, the flowed water drops and collides with the inclined surface 9d of the guide portion 9 immediately below, and most of them flow downward immediately along the inclined surface 9d as shown by the thick arrows in FIGS. 3 and 6. It flows out and is discharged to the left-right side of the case 1 from the open end 9a of the guide part 9. In addition, some water flows through the cylinder 7 side or the half cylinder 7 side, or raises the inclined surface 9d by the force which has fallen, as shown by the arrow that goes over the inclined surface 9d. However, the water which flowed through the half cylinder 7 side flows down to the case upper surface 1u 'of the front of the guide part 9 as shown by the thin arrow, and the water which flowed through the cylinder 7 side is a thin arrow. As shown in the figure, the water splashes from the side surfaces 7f and 8e, flows back to the case upper surface 1u ', and rises the inclined surface 9d to flow into the groove 13 as shown by a thin arrow. It passes through 13f and flows to the case upper surface 1u '. The water flowing into the case upper surface 1u 'flows downward along the inclination of the upper surface 1u' and is discharged from the open end 1p to the left and right sides of the case 1.

According to the above, by providing the guide part 9 which has the inclined surface 9d which inclines in the left-right direction L and R between the case upper surface 1u 'and the front end part 6e of the operation knob 6, Even if water flows from the outside through the gap 18 between the cover 20 and the operation knob 6 and flows near the front end 6e of the operation knob 6 of the case upper surface 1u ', the water is guided. Since it flows along the inclined surface 9d of the part 9 from time to time and is discharged from the open end 9a of the guide part 9 to the left and right of the case 1, the water is operated by the operation knob 6 and the barrel 7 It is possible to prevent the intrusion into the case 1 from the upper and lower openings 7b and 7c of the barrel 7 by raising the gap 19 (FIG. 7).

In addition, in the switch device 100, the width of the left and right directions L and R of the case 1 is shorter than the width of the front and rear directions F and B, and the left and right side surfaces 1l of the case 1 are separated from the cylinder 7. Since the distance to 1r is shorter than the distance to the front and back side surfaces 1f and 1b, the water flows to the left and right sides of the case 1 along the inclined surface 9d of the guide portion 9 as described above. Therefore, the water from the case 1 to the outside can be discharged quickly, thereby making it possible to more reliably prevent the ingress of water into the case 1.

In addition, the gaps 18 are formed by arranging the two guide parts 9 in the form of mountains in the left and right directions L and R such that each inclined surface 9d is inclined downward toward both the left and right directions L and R. The water which has flowed down through it flows down along the inclined surface 9d in both the left and right directions L and R, from the upper opening 7b of the barrel 7 and the front end 6e of the operation knob 6. It can be quickly discharged to the side of the case 1, and further intrusion of water into the case 1 can be prevented.

In addition, the rear end 9c of the guide portion is adjacent to the front side surface 7f of the cylinder 7 and the flange 10 is provided above the guide portion 9 of the front side surface 7f. The water on the inclined surface 9d can flow along the inclined surface 9d of the guide portion 9 along the inclined surface 9d of the guide portion 9 without remaining between the guide portion 9 and the barrel 7. Even if it collides with the front surface 7f of the cylinder 7 and rises, the water passes through the gap 19 between the operation knob 6 and the cylinder 7 to the upper opening 7b of the cylinder 7. Thinness can be prevented by the flange 10, and the intrusion of water into the case 1 can be prevented further.

Moreover, in the vicinity of the guide part 9, the groove | channel 13 with which the edge part 13f was opened so that the guide part 9 may be connected to the left and right side surfaces 1l and 1r of the case 1 is provided. As a result, even if water flows on the opposite side of the guide direction of the guide portion 9, that is, in the R direction or the L direction in which the inclined surface 9d rises due to the force dropped on the inclined surface 9d of the guide portion 9, Water does not enter the groove 13 in that direction and is not returned to the guide portion 9, and the water passes through the open end 13f of the groove 13 and the case upper surface 1u ', and the case 1 Can be discharged to the left and right sides, and further intrusion of water into the case 1 can be prevented.

In addition, water is inclined downward toward the left and right side surfaces 1l and 1r of the case 1 by tilting the case upper surface 1u 'near the front side of the guide portion 9 so that the water is not in the guide direction of the guide portion 9. Direction, that is, in a direction other than the direction in which the inclined surface 9d descends (in the L direction or the R direction) (in the R or L direction in which the inclined surface 9d rises and in the F and B directions crossing the inclined surface 9d). Even if it flows directly or indirectly to the case upper surface 1u ', the water flows along the inclination of the case upper surface 1u' without retaining the water on the case upper surface 1u ', and the case is opened from the open end 1p. It can be easily found to be discharged to the side of (1), and further intrusion of water into the case 1 can be prevented.

The inclined surfaces 9d '", 9f' " facing obliquely upward are inclined downward toward the left and right directions L and R, and the inclined surfaces 9f '" toward the inner side of the case 1 have a groove ( The inclined surface 9d '' ', which is continuous with the bottom 13b of 13, and faces outwards, is continuous with the left and right side surfaces 1l and 1r of the case 1, and the end portions (1r and 1r) on the side surfaces 1l and 1r. 9a '' ') is open.

The guide part 9 "'' shown in FIG. 11 is a plate shape in which the shape seen from the front was inclined obliquely, and consists of the protrusion which protrudes perpendicularly from the rear side 8e of the recessed part 8, and the case upper surface Between 1u 'and the front end part 6e of the operation knob 6, it is provided so that it may become a roughly mountain shape at predetermined intervals in the left-right direction L and R every two for each operation knob 6 etc. The width | variety of the front-back direction of each guide part 9 "" is the magnitude | size equivalent to the guide part 9, and the width | variety (the end part (2) of two guide parts 9 "" which form a rough mountain shape. 9a " ") to the end 9e " " The inclined surfaces 9d '' '' and 9f '' '' which are obliquely upwardly inclined downward toward the left and right directions L and R, and the ends 9a '' '' and 9e '' '' are opened. have.

According to the guide portions 9 ', 9' ', 9' '', 9 '' '' of FIGS. 8 to 11, the front end 6e of the operation knob 6 and the end portion of the cover 20 ( Water flowing down from the gap 18 of 20e to the concave portion 8 is transferred to the guide portions 9 ', 9' ', 9' '', 9 '' '' as shown by arrows in the respective figures. As a result, it can be discharged from side to side of the case 1 at any time, and the water can be prevented from entering the case 1 from the openings 7b and 7c of the case 7. In addition, in the guide parts 9 ", 9 '", 9 "' 'of FIGS. 9-11, between guide parts 9", 9' ", and 9" '' are used. Water may enter between the guides 9 '', 9 '' ', 9' '' 'and the case top surface 1u', but the water flows along the inclination of the case top surface 1u '. Since the liquid is discharged to the left and right sides of the case 1 from the open end 1p, water does not stay in the case upper surface 1u 'and the like.

Moreover, in embodiment mentioned above, although the guide part 9 was provided integrally with the case 1 in the vicinity of the front end part 6e of the operation knob 6, this invention is not limited only to this, The guide portion may be provided integrally with the case in the vicinity of an end portion other than the front side of the operation knob, or the guide portion may be formed separately from the case and then attached to the case.

Moreover, in embodiment mentioned above, providing guide parts 9, 9 ', 9 ", 9'", 9 "'' between the case upper surface 1u 'and the operation knob 6 is provided. For this reason, although the recessed part 8 was provided in the vicinity of the front end part 6e of the operation knob 6 on the case 1, this invention is not limited only to this, An operation knob is provided without providing a recessed part on a case. By increasing the distance between the case top surface and the operation knob, such as by placing the attachment position above the case, a guide portion can be provided between the case top surface and the operation knob. By the way, when the recessed part 8 as mentioned above is provided, since the installation space of a guide part can be ensured between the case upper surface and an operation knob, without raising the attachment position of an operation knob to upper case, it is high. By suppressing this, it is possible to reduce the size of the switch device.

Moreover, in embodiment mentioned above, although the example which provided the upper surface case 1u 'of the guide part 9 vicinity to both the left and right side surfaces 1l and 1r of the case 1 was mentioned, this invention is this only. Instead of limiting, the case upper surface near the guide portion may be provided so as to be continuous with only one of the left and right side surfaces of the case. Also with respect to the guide portion, it may be provided so as to incline downward toward both the left and right sides of the case from a predetermined position, or may be provided so as to incline the downward direction only to either one.

Moreover, in embodiment mentioned above, although the example which applied this invention to the switch apparatus 100 used for the power window apparatus provided with four window opening / closing switches was given, in this invention, only one or four window opening / closing switches are mentioned. It can also be applied to a plurality of other switch devices provided, a switch device used for a door opener and the like. Moreover, it is possible to apply also to the switch apparatus used for uses other than vehicle mounting.

According to the present invention, even if water flows from the outside to the end of the operation knob on the upper surface of the case, since the water flows along the guide part and is discharged to the left and right sides of the case, the water raises the gap between the operation knob and the barrel. This prevents the intrusion into the case from the opening of the cylinder.
