Description

  The present invention relates to a waterproof structure of a switch device in which a contact opens and closes by operating an operation knob.

  Some switch devices whose contacts are opened and closed by operating the operation knob include a structure that creates a feeling of moderation (click feeling) when the operation knob is operated in order to improve the operation feeling.

  For example, in Patent Document 1, an operation knob is swingably attached to a switch body, and a V-shaped moderation surface portion and a stopper are provided on the upper surface of the switch body below the operation knob. Further, a coil spring and a ball are provided on a cylindrical portion protruding from the lower surface of the operation knob, and the ball is elastically contacted with the moderation surface portion by the coil spring. By swinging the operation knob, the moderator slides on the moderation surface portion, and a sense of moderation is generated.

  Further, for example, in Patent Document 2, a cam surface is provided obliquely on a wall portion of a support body in a container (support member), and the rotating body is supported by the support body so as to be able to swing around the shaft, and protrudes above the rotating body. The operation knob is fixed to the protrusion. Further, a coil spring and a holder are provided on a cylindrical urging portion projecting obliquely downward of the rotating body, and the ball at the tip of the holder is brought into elastic contact with the cam surface by the coil spring. By swinging the operation knob and the rotating body, the ball slides on the cam surface, and a feeling of moderation is generated.

  For example, in Patent Document 3, an operation knob (toggle part) is disposed in a rectangular container (base part), and the operation knob is swingably supported by a container with a pin. In addition, a plate-like click member having an opening is connected between the side wall of the container perpendicular to the swinging surface of the operation knob and the side surface of the operation knob. Further, a coil spring and a ball are provided on the operation knob, and the ball is elastically contacted with the click member by the coil spring. By swinging the operation knob, the ball slides on the click member and engages with the opening, thereby generating a sense of moderation.

  For example, in Patent Document 4, a cylinder with a rectangular frame shape is provided on the upper part of a container (casing), and an operation knob is supported on the cylinder so as to be swingable on an axis so as to close an opening at the upper end of the cylinder. In addition, a plate-like drive unit is provided beside both side walls of the cylinder, which is perpendicular to the rocking surface of the operation knob, and the lower end of each drive unit is supported by the operating plate, and the upper end of each drive unit is operated. It is in contact with the inner rib of the knob. Further, a click rubber covering the contacts is provided below the operation plate. By swinging the operation knob, the drive unit is pushed down by the rib, the operating plate is elastically deformed, the click rubber is buckled, and a feeling of moderation is generated.

  For example, in patent document 5, the upper part of a container (housing cover) is covered with the switch cover made of silicon rubber, and the contact is covered with the elastic bending part of the switch cover. In addition, a panel is attached above the container, and an operation knob is attached inside the attachment hole of the panel so as to be swingable about a shaft. Further, both operating portions projecting downward from the operation knob are brought into contact with the elastic bending portion of the switch cover. By swinging the operation knob, the operating portion buckles and deforms the elastic bending portion, and a feeling of moderation is generated.

  Further, for example, in Patent Document 6, an operation knob is supported on a shaft so as to be able to swing around a cylinder provided in a container (housing). A plunger (pin and compression spring) is projected from one of the top surface of the opposing operation knob and the bottom surface of the cylinder, and is in elastic contact with a moderation portion (receiving groove) provided on the other. A pressing body is provided between both side walls perpendicular to the swinging surface of the operation knob and the plunger, and the upper end of each pressing body is brought into contact with a rib inside the operation knob. A substrate is provided below the pressing body, and a rubber switch member is provided between the pressing body and the substrate. The elastic deflection portion (rubber contact portion) of the rubber switch member covers the contact point on the substrate, and supports each pressing body directly from below or via a compression spring. By swinging the operation knob, the pressing body is pushed down by the rib, the elastic bending portion is buckled and deformed, the plunger slides on the moderation portion, and a feeling of moderation is generated.

  By the way, since the electrical contacts and circuits are provided in the container of the switch device, if water or the like (including other liquids) enters, the contacts or circuits may be short-circuited to cause malfunction or corrosion. Failure may occur.

  For example, in the structure as disclosed in Patent Document 1, no water entry prevention measures are taken on the operation knob or the switch body, so that water easily reaches the contact point when bathed. Moreover, in the structure like patent document 2, water will easily infiltrate into the container between the operation knob and the container (support member) and through the hole of the support. Further, even in the structure as in Patent Document 3, water easily enters the container from between the operation knob and the end wall of the container.

  Further, in the structure as disclosed in Patent Document 5, water may enter through the switch cover after entering from between the panel and the operation knob, and may enter the housing from the joint of the side surfaces of the container.

  On the other hand, in the structure as in Patent Document 4, the side wall of the cylinder functions to prevent water from entering the container. However, a predetermined interval is provided between the side wall of the cylinder and the side wall of the operation knob, which is perpendicular to the swing surface of the operation knob, in order to secure a space when the operation knob swings. Yes. For this reason, water rises between the side wall of the operation knob and the side wall of the cylinder, and passes between the gap between the side wall of the cylinder and the drive unit, or between the step at the upper end of the drive unit and the rib of the operation knob. And enters the container. In particular, when the operation knob swings, the drive unit and the inner surface and ribs of the operation knob are separated from each other and the distance between them increases, so that water passes over the drive unit, passes through the inside of the cylinder, and enters the container. There is a risk of intrusion.

  Moreover, in the structure like patent document 6, after water permeates into the inside of a cylinder from between an operation knob and a cylinder, there exists a possibility that it may permeate into a container through the clearance gap between a press body and this holding | maintenance part. is there.

  According to the above, the plunger provided between one of the side walls of the operation knob and one of the side walls of the cylinder, which is perpendicular to the swing surface of the operation knob, even when exposed to a liquid such as water, Since the intrusion of water or the like reaching the opening at the upper end of the cylinder through the cylinder is blocked, it is possible to prevent the water from entering the container 10. In addition, since the protruding direction of the plunger is inclined with respect to the side wall of the cylinder, even if the gap between one of the side walls of the operation knob and one of the side walls of the cylinder is narrow, the movable amount of the plunger is increased and the elasticity is increased. The contact force can be increased to improve the water shielding performance.

  In the present invention, in the above switch device, the side wall of the cylinder parallel to the swinging surface of the operation knob and the side wall of the operation knob may be in linear contact with each other over the lateral width of the side wall of the cylinder. .

  According to the present invention, in the above switch device, the operation shaft, which is the central axis in the protruding direction of the plunger, intersects with the axis of the shaft that supports the operation knob, and is located on the side wall of the cylinder or the operation knob. A moderation portion may be provided that generates a moderation feeling by rubbing against the plunger as the operation knob swings.

  Further, according to the present invention, in the switch device, the operation knob covers the cylinder from above, and the plunger protrudes obliquely upward from the outer surface of the side wall of the cylinder perpendicular to the swinging surface of the operation knob. In addition, the inner surface of the side wall of the operation knob facing the outer surface may be in elastic contact with the linear shape.

  According to the present invention, it is possible to provide a switch device that can prevent liquid from entering the container from between the operation knob and the cylinder even when exposed to liquid such as water.

  The switch device 100 according to the embodiment of the present invention shown in FIGS. 1 to 4 is used in a power window system of an automobile, and is attached to, for example, an armrest (not shown) installed on a door of a passenger seat. The switch device 100 is provided with a window switch W and a door lock switch D.

  The container 10 of the switch apparatus 100 is comprised from the case 10a and the cover 10b, as shown in FIG. The lower side of the case 10a is open and is closed by fitting the cover 10b. A substrate 11, a light guide 12, and a striker 5 are accommodated in the container 10.

  A plurality of fixed contacts 7a to 7e, LEDs 13 (light emitting diodes), and other electronic components (not shown) such as switches and connectors are mounted on the substrate 11, and an electric circuit is formed by these. As shown in FIG. 9, the striker 5 is provided with a plurality of movable contacts 6 a to 6 c made of leaf springs.

  The light guide 12 shown in FIG. 1 is formed of a light transmissive resin molded product such as an acrylic resin. The light guide 12 guides the light emitted from the LED 13 to the display unit 1e of the window switch W and the display units 21e and 21f of the door lock switch D.

  At the upper part of the container 10, rectangular frame-shaped cylinders 2 and 22 are provided integrally with the case 10 a. Each shaft 22j (FIGS. 1 to 3) provided on the outer surface of the cylinder 22 is inserted into each hole 21g (FIGS. 1, 2, and 4) provided on the side surface of the operation knob 21 of the door lock switch D. Fit. Then, as shown in FIGS. 1 to 4, the operation knob 21 closes the opening at the upper end of the cylinder 22 and is supported by the cylinder 22 so as to be swingable by the shaft 22j.

  Each shaft 2j (FIGS. 1, 5, and 6) provided on the inner surface of the cylinder 2 is fitted into each hole 1g (FIGS. 5 and 7) provided on the inner side of the operation knob 1 of the window switch W. Include. Then, as shown in FIGS. 5 and 8, the operation knob 1 closes the opening 2a at the upper end of the cylinder 2, and is supported by the cylinder 2 so as to be swingable by the shaft 2j. That is, the operation knob 1 is attached so as to cover the cylinder 2 from above.

  A small cylindrical portion 2t is provided inside the tube 2 (FIGS. 5, 6, and 8). The protruding portion 12a of the light guide 12 passes through the inside of the small cylindrical portion 2t. An arc portion 5b (FIGS. 5, 8, and 9) of the striker 5 is engaged with the outer peripheral surface on the lower end side of the small cylindrical portion 2t. The striker 5 is placed in the vicinity of the fixed contacts 7 a to 7 e on the substrate 11.

  A lever 8 is provided inside the operation knob 1 (FIGS. 1, 5, and 7 to 9). As shown in FIGS. 5 and 8, the lever 8 penetrates the inside of the cylinder 2. A concave portion 8 a provided at the lower end of the lever 8 is engaged with a convex portion 5 a provided on the striker 5.

  The operation knob 1 is moved from the neutral state shown in FIGS. 8 (a) and 9 (a) to the axis 2j as shown in FIGS. 8 (b) to 8 (e) and FIGS. 9 (b) and 9 (c). When the swinging operation is performed, the lever 8 is tilted, and the striker 5 is rotated along the outer peripheral surface of the small cylindrical portion 2t. Thereby, the movable contacts 6a-6c provided in the striker 5 slide on the board | substrate 11, and contact / separate with respect to the fixed contacts 7a-7e. That is, by swinging the operation knob 1, the movable contacts 6a to 6c and the fixed contacts 7a to 7e are opened and closed (OFF / ON).

  A plunger 3 is provided on the side wall 2f side of one side (front side F) of the cylinder 2 perpendicular to the swinging surface of the operation knob 1 (a surface orthogonal to the central axis of the shaft 2j in FIG. 8). . The plunger 3 is formed of resin and has a width that extends across the lateral width of the side wall 2f of the tube 2 as shown in FIG. That is, the lateral width of the plunger 3 is equal to or greater than the lateral width of the side wall 2f.

  As shown in FIGS. 1 and 6, a groove 2 k is provided in the upper part of the side wall 2 f of the cylinder 2 over the lateral width. The groove 2k is recessed obliquely with respect to the side wall 2f and opens obliquely upward. After inserting the plunger 3 together with the coil spring 4 into the groove 2k, the operation knob 1 is attached to the cylinder 2 as described above. Then, as shown in FIG. 8, the plunger 3 protrudes obliquely upward from the side wall 2f of the cylinder 2 by the elastic force of the coil spring 4, and extends across the lateral width to the side wall 1f of the operation knob 1 facing the side wall 2f. It makes elastic contact in a linear shape. This elastic contact state is maintained regardless of the swinging state of the operation knob 1, as shown in FIGS. Thereby, the plunger 3 functions as a water-impervious wall.

  In FIG. 8, the protruding direction of the plunger 3 is oblique with respect to the side wall 2 f of the cylinder 2. 8A, the operating axis M, which is the central axis in the protruding direction of the plunger 3, and the side wall 1f of the operation knob 1 form an acute angle. The operation axis M of the plunger 3 intersects the axis of the axis 2j that supports the operation knob 1.

  A moderation portion 1 s is provided on the upper portion of the side wall 1 f of the operation knob 1. The moderation portion 1s is composed of valley portions 1r and 1v and mountain-shaped inclined portions 1p and 1q. A pair of valley 1v and inclined portions 1p, 1q are provided with a valley 1r interposed therebetween. The upper inclined portion 1q extends to the upper wall 1u of the operation knob 1. The moderation portion 1s is formed on the back side of the front head 1c of the operation knob 1 so as to face obliquely downward.

  The plunger 3 is pressed against the moderation portion 1 s provided on the side wall 1 f by the elastic force of the coil spring 4. As the operation knob 1 swings, the plunger 3 and the moderation portion 1s rub against each other, thereby generating a moderation feeling (click feeling). Therefore, the plunger 3 also functions as a moderator.

  Specifically, as shown in FIG. 8A, when the operation knob 1 is in a neutral state, the tip of the plunger 3 is engaged with the valley 1r of the moderation portion 1s. From this neutral state, as shown in FIG. 8B, when the operation knob 1 is swung in a forward tilt direction at a small angle, the tip of the plunger 3 engages with the inclined portion 1p on the upper side of the moderation portion 1s. Sense of moderation occurs. Further, as shown in FIG. 8 (c), when the operation knob 1 is swung at a large angle in the forward tilt direction, the tip of the plunger 3 passes over the upper valley portion 1v of the moderation portion 1s and the upper inclined portion 1q. A feeling of moderation occurs.

  Further, as shown in FIG. 8 (d), when the operation knob 1 is swung back at a small angle from the neutral state at a small angle, the tip of the plunger 3 is engaged with the lower inclined portion 1p of the moderation portion 1s. Thus, a sense of moderation occurs. Further, as shown in FIG. 8 (e), when the operation knob 1 is swung in a backward tilt direction at a large angle, the tip of the plunger 3 passes over the lower valley 1v of the moderation portion 1s and is inclined downward. A feeling of moderation is generated by engaging the portion 1q.

  On the outer surface of the side wall 2m, 2h of the cylinder 2 parallel to the swinging surface of the operation knob 1, as shown in FIG. As shown in FIG. 5, the side walls 2 m, 2 h of the cylinder 2 and the side walls 1 m, 1 h of the operation knob 1 facing the projection 2 n are lined across the lateral width of the side walls 2 m, 2 h of the cylinder 2. It touches the shape. Further, waterproof grease is applied between the side walls 2m and 2h of the cylinder 2 and the side walls 1m and 1h of the operation knob 1 (not shown).

  As shown in FIGS. 7 and 9, etc., recesses 1z are provided at the lower ends of the side walls 1m and 1h of the operation knob 1. A convex limiting wall 2z is provided at the lower end of the outer surface of the side walls 2m and 2h of the tube 2 as shown in FIGS. As shown in FIGS. 2, 4, and 5, the upper portion of the limiting wall 2z enters the recess 1z.

  According to the embodiment, the plunger 3 is provided on the side of the side wall 2f of the cylinder 2 perpendicular to the swinging surface of the operation knob 1 over the lateral width of the side wall 2f. The plunger 3 protrudes from the side wall 2f of the cylinder 2 and is in elastic contact with the side wall 1f of the operation knob 1 facing the side wall 2f in a linear manner across the width regardless of the swinging state of the operation knob 1. . For this reason, even if it is exposed to liquid such as water, the plunger 3 causes the plunger 3 to enter the opening 2a at the upper end of the cylinder 2 through the side wall 1f of the operation knob 1 and the side wall 2f of the cylinder 2. By blocking, water intrusion into the container 10 can be prevented. Further, since the protruding direction of the plunger 3 is inclined with respect to the side wall 2f of the cylinder 2, the plunger 3 can be moved even if the gap between the side wall 1f of the operation knob 1 and the side wall 2f of the cylinder 2 is narrow. By increasing the amount, the elastic contact force can be increased and the water shielding performance can be enhanced.

  In particular, in the present embodiment, the plunger 3 is provided between the side wall 2 f on the front side F (FIGS. 2 and 7) and the side wall 1 f of the operation knob 1 among the side walls 2 f and 2 b of the cylinder 2. For this reason, when the switch device 100 is tilted backward (in a state where the window switch W is lower than the door lock switch D) and attached to the armrest, the switch device 100 flows down the upper surface of the inclined container 10 from between the side walls 1f and 2f. The penetration of water to the opening 2 a at the upper end of the cylinder 2 can be reliably blocked by the plunger 3.

  Moreover, in the said embodiment, the side walls 2m and 2h of the cylinder 2 parallel to the rocking | fluctuation surface of the operation knob 1 and the side walls 1m and 1h of the operation knob 1 span the width of the side walls 2m and 2h by the convex part 2n. It touches linearly. For this reason, it is possible to block water from entering the opening 2a at the upper end of the cylinder 2 through the space between the side walls 2m and 2h of the cylinder 2 and the side walls 1m and 1h of the operation knob 1.

  Moreover, in the said embodiment, the moderation part 1s is provided in the side wall 1f of the operation knob 1 with which the plunger 3 elastically contacts. The operation axis M of the plunger 3 intersects the axis of the axis 2j that supports the operation knob 1. For this reason, when the operation knob 1 swings around the axis 2j, a clear sense of moderation is generated, and the operation knob 1 can be returned to the neutral state when the operation is released while improving the operation feeling. In addition, since the plunger 3 has both functions of a water shielding wall and a moderation element, it is not necessary to provide a moderation portion or moderation element in the internal space of the cylinder or the container as in the prior art. Can be effectively used separately.

  Specifically, in the above embodiment, the light guide 12 and the lever 8 are provided inside the cylinder 2, and the striker 5 and the contacts 6 a to 6 c and 7 a to 7 e are provided inside the nearby container 10. For this reason, components are densely packed and the switch apparatus 100 can be reduced in size. Further, in the door lock switch D, the operation knob 21 is attached to the cylinder 22 with an outer fitting structure in which the shaft 22j and the hole 21g are exposed to the outside, but in the window switch W, the shaft 2j and the hole 1g are connected to the cylinder 2. The operation knob 1 is attached to the cylinder 2 with an internal fitting structure provided inside the operation knob 1. For this reason, generation | occurrence | production of the crack of the operation knob 1 and the bleeding of the grease apply | coated between the side walls 1m and 1h of the operation knob 1 and the side walls 2m and 2h of the cylinder 2 can be suppressed.

  Further, in the above embodiment, the operation knob 1 is covered from the upper side of the cylinder 2, and the plunger 3 is projected obliquely upward from the outer surface of the side wall 2 f of the cylinder 2, so that the line is formed on the inner surface of the side wall 1 f of the operation knob 1. In elastic contact. For this reason, the width of the operation knob 1 and the cylinder 2 in the direction parallel to the swing surface of the operation knob 1 can be reduced. Further, since the plunger 3 faces obliquely upward and the moderation portion 1s faces obliquely downward so as to face it, the plunger 3 is inserted into the groove 2k of the tube 2 and then the side wall 1f and the moderation of the operation knob 1 are inserted. The operation knob 1 can be attached to the cylinder 2 while the plunger 3 is smoothly pushed into the groove 2k by the portion 1s, which facilitates assembly.

  The present invention can employ various embodiments other than those described above. For example, in the above-described embodiment, the plunger 3 is protruded obliquely upward from the side wall 2f on the front side F of the cylinder 2 perpendicular to the swinging surface of the operation knob 1 to the side wall 1f on the front side F of the control knob 1. Although an example of elastic contact in a linear shape has been shown, the present invention is not limited to this.

  For example, as shown in FIG. 10, the plunger 3 may be protruded obliquely downward from the inner surface of the side wall 1 f of the operation knob 1 and may be elastically contacted linearly with the outer surface of the side wall 2 f of the cylinder 2. Further, for example, as shown in FIG. 11, the plunger 3 protrudes obliquely upward from the side wall 2 b on the rear side B of the cylinder 2 and is brought into elastic contact with the side wall 1 b on the rear side B of the operation knob 1 in a linear manner. Also good. 10 and 11, the protruding direction of the plunger 3 is inclined with respect to the side walls 2 f and 2 b of the cylinder 2, and the operation axis M of the plunger 3 is the axis of the shaft 2 j that supports the operation knob 1. Interact with.

  Furthermore, for example, as shown in FIG. 12, when the operation knob 1 is pivotably supported inside the cylinder 2, the plunger 3 is placed perpendicular to the swinging surface of the operation knob 1. It may be made to project obliquely downward from the outer surface of the side wall 1b of the tube 2 and to be elastically contacted linearly with the inner surface of the side wall 2b of the tube 2. Also in this case, the protruding direction of the plunger 3 is inclined with respect to the side wall 2 b of the cylinder 2, and the operation axis M of the plunger 3 intersects the axis of the axis 2 j that supports the operation knob 1.

  That is, the plunger 3 may be provided on either the front side F or the rear side B of the operation knob 1, and is perpendicular to the swinging surface of the operation knob 1 and the side walls 1 f, 1 b, 2 f of the operation knob 1 and the cylinder 2. 2b may protrude diagonally upward or diagonally downward from any one of the side walls and elastically contact the opposite side wall. When a moderation portion 1 s is provided on the side wall with which the plunger 3 is elastically contacted, for example, as shown in FIGS. 10 to 12, a moderation feeling can be generated when the operation knob 1 is swung.

  The plunger 3 may be provided on both the front side F and the rear side B of the operation knob 1. In this case, for example, the structure shown in FIG. 8 is adopted for the plunger 3 on the front side F, and the structure shown in FIG. 11 is adopted for the plunger 3 on the rear side B, for example.

  Further, as shown in FIGS. 11 and 12, when the plunger 3 is provided on the rear side B of the operation knob 1, the switch device 100 is tilted forward (the window switch W is positioned higher than the door lock switch D). ), The plunger 3 can reliably block the intrusion of water that flows down the upper surface of the inclined container 10 and reaches the opening 2a at the upper end of the cylinder 2 from between the side walls 1b and 2b. .

  In the above embodiment, the moderation portion 1s is provided on the side wall 1f of the operation knob 1 or the side wall 2f of the cylinder 2. However, the moderation portion 1s may be omitted. That is, the plunger 3 may be used only as a water shielding wall. In this case, the coil spring 4 is omitted, the plunger 3 is formed of an elastic material such as rubber, and the plunger 3 is elastically brought into contact with the side wall 1f of the operation knob 1 or the side wall 2f of the cylinder 2 by its own elastic force. May be.

  In the above-described embodiment, the operation axis M of the plunger 3 intersects with the axis of the axis 2j that supports the operation knob 1. However, the operation axis M and the axis of the axis 2j do not have to intersect. .

  Moreover, in the said embodiment, the side walls 2m and 2h of the cylinder 2 parallel to the rocking | fluctuation surface of the operation knob 1 and the side walls 1m and 1h of the operation knob 1 are spread over the width of the side walls 2m and 2h by the convex part 2n. However, the present invention is not limited to this example. In addition to this, for example, the side walls 2m and 2h of the cylinder 2 and the side walls 1m and 1h of the operation knob 1 may be brought into surface contact to form a local line contact portion.

  Further, in the above-described embodiment, the example in which the present invention is applied to the window switch W of the switch device 100 used in the power window system has been described, but the present invention can also be applied to the door lock switch D. The present invention can also be applied to a switch device used for purposes other than in-vehicle use.
