Detailed Description

Hereinafter, the present embodiment will be described in detail with reference to the drawings.

Fig. 1 to 9 are diagrams for explaining this embodiment.

Example 1

The structure of this embodiment will be described below.

For example, various switches (switching devices) are provided in a vehicle interior of a vehicle such as an automobile. As shown in fig. 1 (to 6), this switching device 100 is configured to have:

a case 103 having a square tubular shape and having a light source 101 and a switch contact 102 in an inner depth portion;

a switch knob 106 provided so as to cover an opening 104 (fig. 4) on the near side of the housing 103, and movable in an axial direction 105 of the housing 103 and illuminated by transmission; and

and a slide member 107 disposed inside the housing 103, for pressing the switch contact 102 by movement of the switch knob 106 in the axial direction 105.

Here, in the switching device 100 provided in the vehicle interior, there are various switches such as a hazard warning switch for operating on/off of a hazard warning lamp, a switch for an air conditioner, a sound, and the like, a switch for controlling functions of the vehicle, and the like.

In the light source 101, an LED and other light sources may be used. As the switch contact 102, a small-sized push-button switch such as a tact switch (tact switch) or other switch can be used. The switch contact portion 102 of the tact switch or the like has a return spring for returning to a state before being pushed into the inside. The light source 101 and the switch contact 102 may be disposed in the opening 109 on the deep side of the case 103 in a state of being mounted on (the same substrate surface as) the (circuit) substrate 108. By providing the light source 101 and the switch contact portion 102 on the same substrate 108 in this way, various elements (the light source 101, the switch contact portion 102, and the like) can be integrated on one substrate 108, and since only a plurality of elements are mounted on one substrate 108, the production efficiency is improved. Further, only one substrate 108 may be mounted in the case 103, and thus space efficiency may be improved.

The light source 101 is disposed at a central portion in the width direction of the substrate 108, and is disposed at a position close to the central portion of the case 103. The switch contact portion 102 is provided at a side portion or the like in the width direction of the substrate 108, and is provided at a position close to the side surfaces 111 to 114 (fig. 5 or 6) of the case 103, for example, at a position close to one side surface 111. A member (terminal block 115) serving as a terminal for connecting wiring for supplying power to the substrate 108, transmitting signals, and the like is provided on the surface of the substrate 108 on the deep side.

As described above, the square tubular case 103 has four side surfaces 111 to 114, and openings 104 and 109 at both ends. A flange 116 extending outward is provided at an intermediate portion in the axial direction 105 of the housing 103. The housing 103 may have a uniform size, cross-sectional shape, etc. over the entire region in the axial direction 105, but for example, the size, cross-sectional shape, etc. of the near-side portion (housing near-front portion 117) and the deep-side portion (housing deep portion 118) may be changed with the flange portion 116 as a boundary. In this embodiment, a stepped portion is provided at the position of the flange portion 116 to form the case heel portion 117 larger than the case deep portion 118.

The switch knob 106 may be a cap-shaped member made of transparent resin. The switch knob 106 has a pressing surface 121 on the near side, and an outer peripheral wall 122 extending deep in the peripheral edge of the pressing surface 121. The pressing surface 121 may be provided with a display 123 for displaying symbols, graphics, characters, and the like representing the operation contents of the switching device 100. The display portion 123 is made light-transmissive (transmissive illumination portion) by coating or the like, and the other portion is made light-blocking (light shielding portion), whereby the display portion 123 can be transmissive illuminated (the display portion 123 is made to emit light) by turning on the light source 101.

An inner peripheral wall portion 124 is provided on the inner side of the outer peripheral wall portion 122 of the switch knob 106 with a space from the outer peripheral wall portion 122. The inner peripheral wall portion 124 is provided to integrally extend from the back surface side of the pressing surface 121 toward the axial direction 105. The inner peripheral wall portion 124 is fitted to a portion of the casing 103 on the near side (casing near portion 117). The inner peripheral wall portion 124 and the outer peripheral wall portion 122 may be completely separated, may be partially connected, or may share a part. The inner peripheral wall portion 124 is formed to have substantially the same outer shape as the flange portion 116. The outer peripheral wall portion 122 may be formed larger than the flange portion 116. A pressing projection 125 for pressing the slide member 107 integrally protrudes from the back surface side of the pressing surface 121 of the switch knob 106.

The switch knob 106 is movable in the axial direction 105 with respect to the housing 103 until the slide member 107 presses down the switch contact portion 102 and stops (or a distance equal to the pressing stroke of the switch contact portion 102). The switch knob 106 can be restored to the initial position by the elastic restoring force of the return spring provided inside the switch contact portion 102.

The sliding member 107 may be of any structure as long as the switch contact portion 102 can be pressed by the pressing operation of the switch knob 106, but is preferably as follows.

(1) The slide member 107 (fig. 7 and 8) is configured to be separated from the switch knob 106. The slide member 107 is set to have: a body portion 131 having a plate shape and extending along one side surface 111 of the housing 103; a switch pressing portion 132 bent from a deep portion of the body portion 131 toward the inside of the housing 103, for pressing the switch contact portion 102; and a knob abutting portion 133 that is pushed in by the switch knob 106 at a position (offset 134, fig. 2) offset from the front side of the body portion 131 to be closer to the one side surface 111 than the switch pressing portion 132.

The light source 101 and the switch contact portion 102 are provided on the same surface of the substrate 108, the switch contact portion 102 is located closer to one side 111 than the light source 101,

when viewed from the opening 104, the light source 101, the switch pressing portion 132, and the knob (knob) abutting portion 133 are arranged in this order from the light source 101 toward the one side surface 111.

Here, the slide member 107 is formed as a part different from the housing 103, and is housed in the housing 103 so as to be movable in the axial direction 105 independently of the housing 103.

The body 131 is formed in a plate shape parallel to the one side surface 111 of the housing 103. The body portion 131 is disposed so as to span between the case heel front portion 117 and the case deep portion 118.

The switch pressing portion 132 has a bent portion 135 formed at an end portion of the body portion 131 on the deep side and parallel to the substrate 108. A protrusion 136 for pressing down the switch contact 102 may be provided on the deep side of the bent portion 135 as necessary. The bent portion 135 is provided so as to be bent inward of the case 103, and is provided so as to cover substantially the size and shape of the switch contact portion 102. In this embodiment, the bent portion 135 is formed in a planar shape (bent face portion). The bent portion 135 and the protruding portion 136 are formed at positions where the switch contact portion 102 can be directly pressed down.

The knob abutting portion 133 has another bending portion 137 formed at the end of the body portion 131 on the near side and bent toward the one side surface 111 side. If necessary, another protrusion 138 may be provided on the front side of the other bent portion 137. The other bending portion 137 may be provided at a part of the body portion 131. In this embodiment, the other bending portion 137 is formed in a block shape (block-shaped portion) provided on one side of the main body portion 131. The other bending portion 137 in the block shape is provided at the position of the case heel portion 117 by the stepped shape of the case heel portion 117 and the case deep portion 118.

The slide member 107 is positioned between the switch contact 102 and the switch knob 106 in a state where the deep-side protrusion 136 is in contact with the switch contact 102 and the front-side other protrusion 138 is in contact with the pressing protrusion 125.

The offset means that the positions of the knob abutting portion 133 and the switch pressing portion 132 are shifted in the plane direction of the pressing surface 121 (the direction perpendicular to the axis direction 105). The knob contact portion 133 and the switch pressing portion 132 of the slide member 107 are arranged on the opposite side of the body portion 131 of the slide member 107 in the direction perpendicular to the body portion 131 of the slide member 107, thereby being offset in the direction perpendicular to the surface of the body portion 131.

(2) A guide portion 141 for guiding the movement of the slide member 107 in the axial direction 105 is preferably provided between the housing 103 and the slide member 107.

Preferably, the guide portion 141 has a first guide 142 that guides a portion on the near side of the body portion 131 (a side surface of the knob abutment portion 133) and a second guide 143 that guides the body portion 131 (fig. 5).

Here, the guide portion 141 is provided as a guide for the sliding member in the housing 103 or the like. The knob contact portion 133 is formed in a shape bent from the main body portion 131 toward the one side surface 111.

As shown in fig. 4, the first guide 142 is formed between the side surface of the other folded portion 137, the side surface of the body portion 131 on the front side on the opposite side of the other folded portion 137, and the opposite side surfaces 112, 113 of the housing 103. The first guide 142 may include a notch portion 144 formed at the opposite side surfaces 112, 113 of the housing 103 and extending in the axial direction 105, a guide rib 145 extending from a side surface of the other folded portion 137, a side surface located at a front side of the body portion 131 on the opposite side of the other folded portion 137 and slidably fitted into the notch portion 144, and the like.

Further, as shown in fig. 9, the first guides 142 formed on both sides of the near side portion of the body portion 131 of the slide member 107 are offset (offset arrangement) from each other. Thus, even if the operating force applied from the operating knob (the pushing protrusion 125 of the switch knob 106) to the slide member 107 is an eccentric load to the slide member 107, the eccentric load can be received at a position between the first guides 142 on both sides of the offset arrangement, and therefore the slide member 107 is less likely to fall.

As shown in fig. 5, the second guide 143 is formed between two side surfaces 146 of the body portion 131 (of the portion other than the first guide 142, etc.) and the opposite side surfaces 112, 113 of the housing 103. The second guide 143 can include guide ribs 147, guide groove portions, and the like formed on the opposite side surfaces 112, 113 of the housing 103 and extending in the axial direction 105. The guide ribs 147 are provided in a pair so as to lie against both side surfaces 146 of the body portion 131, and slidably support both side surfaces 146 of the body portion 131.

The guide rib 145 of the first guide 142 is formed to have a length reaching the outer wall surface of the housing 103, and the two side surfaces 146 of the body portion 131, which becomes the second guide 143, are formed to have a length not reaching the inner wall surface of the housing 103. Although both the first guide 142 and the second guide 143 are preferably provided, only one of them (in particular, the second guide 143) may be provided in terms of structure.

(3) The guide portion 141 may have a third guide 151 between the one side surface 111 of the housing 103 and the facing surface of the slide member 107.

Here, the facing surface of the slide member 107 is a surface on the side of the one side surface 111 of the body 131.

The third guide 151 may have a structure in which a guide rib 152 protruding from the surface of the one side surface 111 side of the body portion 131 and extending in the axial direction 105, a guide concave portion 153 formed on the inner surface side of the one side surface 111 of the housing 103 and extending in the axial direction 105, and the like. One or more guide ribs 152 may be provided on the surface of the body portion 131 on the side of the one side surface 111 at a position on the opposite side in the width direction from the other folded portion 137. The guide recess 153 is provided to sandwich both side surfaces of the guide rib 152 and slidably supports the guide rib 152. In contrast to the above, the guide rib 152 may be provided in the housing 103, and the guide concave portion 153 may be provided in the body portion 131.

(4) As shown in fig. 7, the sliding member 107 preferably has a reinforcing rib 161 between the body portion 131 and the switch pressing portion 132. The reinforcing rib 161 preferably has an inclined portion 162 that is inclined toward the one side surface 111 as it proceeds toward the near side.

Here, the reinforcing rib 161 is provided so as to extend between (the surface on the opposite side of) the body portion 131 and (the surface on the near side of) the bent portion 135 of the switch pressing portion 132 and face the center of the case 103. A pair of reinforcing ribs 161 are provided near both side portions of the slide member 107 (at positions inside the body portion 131 than the front end portion of the guide concave portion 153).

The inclined portion 162 may be disposed across the entire area of the edge portion of the reinforcing rib 161. Thereby, the reinforcing rib 161 becomes a triangular rib. The inclined portion 162 may be provided at the edge portion on the near side of the reinforcing rib 161, and the edge portion on the deep side of the reinforcing rib 161 may be formed parallel to the axial direction 105. Thereby, the reinforcing rib 161 becomes a trapezoidal rib, and the rib width can be reduced while maintaining a desired reinforcing effect. Only one of the triangular rib and the trapezoidal rib may be provided, or both may be provided in combination as appropriate.

(5) As shown in fig. 1, an engagement portion 171 for engaging the switch knob 106 so as to be movable in the axial direction 105 may be provided between the housing 103 and the switch knob 106.

As shown in fig. 5, another guide portion 172 that guides the movement of the switch knob 106 in the axial direction 105 may be provided between the outer side surface of the housing 103 and the inner side surface of the switch knob 106.

Here, the locking portion 171 is provided between the case front portion 117 and the inner peripheral wall portion 124 of the switch knob 106. The locking portion 171 may have a locking claw 173 provided at the case front portion 117 and a locking hole 174 formed in the inner peripheral wall portion 124 of the switch knob 106. The locking hole 174 is formed as a long hole or the like extending in the axis direction 105 substantially the same as or larger than the movement amount of the switch knob 106 so as to allow the switch knob 106 to move in the axis direction 105. A notch 175 or the like for exposing the locking hole 174 to the outside may be provided at a position facing the locking hole 174 in the outer peripheral wall portion 122 of the switch knob 106. The locking portions 171 may be provided on the one side surface 111 and the other side surface 114 of the housing 103, respectively.

The other guide portion 172 is provided as a guide for the switch knob. The other guide portion 172 may have a guide rib 176 provided on the inner surface side of the inner peripheral wall portion 124 of the switch knob 106 and extending in the axial direction 105, and a guide concave portion 177 provided on the outer side of each of the side surfaces 111 to 114 of the case heel portion 117 and extending in the axial direction 105. The guide rib 176 is slidably fitted in the guide recess 177. The provision of the other guide portions 172 on the respective faces of the rectangular housing 103 is preferable for suppressing tilting of the switch knob 106 when pressed. The other guide portions 172 provided on the respective surfaces of the housing 103 may be provided at the same positions as the other guide portions 172 provided on the opposite surfaces, but are preferably provided at positions offset from each other in terms of further reducing the inclination of the switch knob 106. In contrast to the above, the guide rib 176 may be provided in the housing 103, and the guide concave 177 may be provided in the inner peripheral wall 124.

In addition, as another configuration, a locking claw portion 181 (fig. 1) for attaching the side panel of the vehicle body may be provided in the case deep portion 118. The locking claw portions 181 may be provided on one side surface 111 and the other side surface 114 of the housing 103, respectively. At least at the corner portion of one side surface 111, a U-shaped rib 182 (fig. 3) may be formed in the case deep portion 118 so as to surround one locking claw portion 181. The U-shaped rib 182 is preferably formed so as to include the flange portion 116. Further, a notch 183 (fig. 4) having a C-plane (i.e., 45 ° plane) shape may be provided in the corner portion of the other side surface 114 in the case deep portion 118. These U-shaped ribs 182 and C-shaped cutout portions 183 enhance the rigidity of the housing 103, and effectively prevent reverse assembly of the body side panels (assembly of correct components in the wrong direction).

< action > hereinafter, an action of this example will be described.

The switch device 100 presses the switch contact portion 102 via the slide member 107 by pressing the switch knob 106. The display portion 123 of the switch knob 106 may be transilluminated by illuminating the light source 101.

In this case, in order to miniaturize the switching device 100, "light source 101", "switch contact portion 102" and "sliding member 107" are densely arranged in the housing 103, and "light source 101", "switch contact portion 102" and "sliding member 107" are all intensively arranged in the housing 103. This makes it possible to unitize the portions other than the switch knob 106, and thus can be used for various types of vehicles.

Further, if only the "light source 101" and the "switch contact portion 102" are arranged on the same substrate 108 and the "light source 101", the "switch contact portion 102" and the "sliding member 107" are densely arranged in the switch knob 106, there is a concern that the irradiation range of the light from the "light source 101" may be narrowed by pressing the sliding member 107 of the switch contact portion 102.

In particular, when the display portion 123 and the switch contact portion 102 are partially overlapped in a plan view of the switch device 100, this problem becomes apparent.

Thus, the structure as described above is formed in this embodiment. By forming such a structure, a space free from a shield can be formed above the switch pressing portion 132 of the slide member 107, and the irradiation range of light from the light source 101 can be enlarged accordingly.

< effects > according to this embodiment, the following effects can be obtained.

(effect 1) the slide member 107 is formed in a shape extending along one side 111 of the housing 103. Thus, the body 131 of the sliding member 107 can be formed in a plate shape parallel to the one side surface 111 of the housing 103, and therefore, the remaining three surfaces of the housing 103 are not covered with the sliding member 107, and thus, the illumination range for the switch knob 106 can be widened. Therefore, miniaturization of (the unit portion other than the switch knob 106 of) the switching device 100 can be achieved while securing the illumination range to a desired size. At this time, since the body portion 131 of the slide member 107 is formed in a plate shape, a square illumination range can be ensured.

The knob abutment portion 133 of the slide member 107 is offset with respect to the switch pressing portion 132. Thus, the knob contact portion 133 is less likely to block light from the light source 101, and thus the illumination range can be further widened.

The sliding member 107 is separated from the switch knob 106. Thereby, the function of the slide member 107 can be limited to the operation of the switch contact portion 102. Thus, the sliding member 107 can be simplified.

By separating the slide member 107 from the switch knob 106, the switch knob 106 and the housing 103 are in one-to-one relationship without considering the slide member 107, and thus the assembly accuracy between the switch knob 106 and the housing 103 can be improved and the amount of rattling can be reduced. Further, by separating the slide member 107 from the switch knob 106 so that the switch knob 106 is assembled at the end of the switch device 100, and by manufacturing the switch device 100 (a unit portion of the switch device 100) without the switch knob 106 in advance, the switch knob 106 of different specifications is assembled in the unit portion, and various switch devices 100 and the like can be manufactured separately.

(effect 2) the guide portion 141 for the slide member 107 may be provided divided into the first guide 142 and the second guide 143. This increases the guide length of the entire guide portion 141, and suppresses the inclination of the slide member 107.

The sliding member 107 having the knob abutting portion 133 and the switch pressing portion 132 offset may be inclined in the out-of-plane direction or the like due to the deflection of the force pressing the switch knob 106 (eccentric load), but the inclination of the sliding member 107 is suppressed by dividing the guide portion 141 into the first guide 142 and the second guide 143, and the inclination of the sliding member 107 due to the eccentric load can be prevented. Therefore, the switch knob 106 is prevented from sticking (stuck, which is hard to be flicked), and the switch pressing portion 132 is prevented from being positionally displaced with respect to the switch contact portion 102.

In addition, as shown in fig. 9, the first guides 142 formed on both sides of the near side portion of the body portion 131 of the slide member 107 may be offset (offset arrangement) from each other. Thus, even if the operating force applied to the slide member 107 from the operating knob (the pushing protrusion 125 of the switch knob 106) is an eccentric load to the slide member 107, the eccentric load can be received at a position between the first guides 142 on both sides of the offset arrangement, and therefore, the slide member 107 can be made unlikely to fall.

By dividing the guide portion 141 into the first guide 142 and the second guide 143, the degree of freedom in layout of the slide member 107 and the guide portion 141 can be improved.

(effect 3) the guide portion 141 may have a third guide 151 between the one side surface 111 of the housing 103 and the opposite surface of the slide member 107. This can prevent the slide member 107 from tilting laterally.

(effect 4) the sliding member 107 may have a reinforcing rib 161 between the body portion 131 and the switch pressing portion 132. Thereby, the switch pressing portion 132 can be reinforced with respect to the body portion 131 of the slide member 107. Therefore, even if the switch pressing portion 132 is provided in an offset manner, the switch contact portion 102 can be pressed down using the switch pressing portion 132 without any problem.

The reinforcing rib 161 may have an inclined portion 162 that approaches the one side surface 111 side of the case 103 as advancing toward the near side. Thus, the inclined portion 162 can prevent the reinforcing rib 161 from blocking the light from the light source 101, thereby preventing the illumination range from narrowing.

(effect 5) an engagement portion 171 may be provided between the case 103 and the switch knob 106. Thus, the switch knob 106 can be easily locked to the housing 103 by the locking portion 171, and the switch knob 106 can be easily attached and detached. Therefore, repair, replacement, etc. of the switch knob 106 can be easily performed.

Another guide portion 172 may be provided between the outer side surface of the housing 103 and the inner side surface of the switch knob 106. Thus, the other guide portion 172 for guiding the pressing of the switch knob 106 is removed from the inside of the housing 103, and therefore, the illumination range can be enlarged accordingly. Therefore, (unit portions of) the switching device 100 can be miniaturized.

By providing the other guide portion 172 for guiding the switch knob 106 on the outer side surface of the housing 103, it is possible to facilitate the application of the lubricant to the other guide portion 172, and at the same time, it is possible to apply the lubricant to the other guide portion 172 in the final stage (when the switch knob 106 is mounted).

Since the other guide portion 172 is provided on the inner side surface of the switch knob 106, it is not necessary to mask (mask) the switch knob 106 when the display portion 123 or the like is formed on the switch knob 106 by painting.
