Description

  The present invention relates to a switch device suitable for setting according to an operation amount of a user.

  As this type of switch device, for example, a rotary switch is known. This rotary switch has a configuration in which a rotary encoder detects an operation amount of a rotary dial. In this case, when the rotary dial is operated in one direction, the level to be set is set in the increasing direction, and when the rotary dial is operated in the other direction, the level to be set is set in the decreasing direction. However, this has a problem that the rotary encoder is expensive and expensive.

  As a solution to this problem, there is a switch device described in Patent Document 1. In this configuration, the first cam body and the second cam body interlocking with the rotation of the rotation operation member are provided on the same axis, and the first cam body can be engaged with, for example, a plurality of pieces that can be engaged in the clockwise direction. The first cam body is formed with a plurality of claw-shaped cam parts that can be engaged in the counterclockwise direction, and the first cam body is clockwise with respect to the first cam body. A first pusher that engages with the cam portion of the cam body is provided, and the second pusher engages with the cam portion of the second cam body in a counterclockwise direction with respect to the second cam body. The pusher is provided, the first switch is operated by the pusher, and the second switch is operated by the another pusher.

That is, the cam body, the pusher, and the switch constitute a set of mechanisms, and the mechanism includes two sets. In this case, when the rotation operation member is rotated clockwise, the first pusher operates the switch a number of times corresponding to the rotation amount (rotation angle), and the rotation operation member is rotated counterclockwise. When rotated, the second pusher operates the switch a number of times corresponding to the amount of rotation (rotation angle).

Accordingly, the first switch is operated at a number of times corresponding to the moving amount of the moving element. Therefore, the movement of the moving element in the forward direction can be detected by the operation of the first switch, and the movement amount can be detected by the number of operations of the first switch. Further, when the moving element is moved in the backward direction, the plurality of operating elements are moved in the backward direction, and the second switch operating body is operated in one direction according to the arrangement interval of the operating elements. The switch is operated a number of times corresponding to the amount of movement of the slider. Therefore, the movement of the moving element in the backward direction can be detected by the operation of the second switch, and the movement amount can be detected by the number of operations of the second switch.

  In either the forward direction or the backward direction of the moving element, the operating element operates the first switch operating body and the second switch operating body, and consequently operates the first switch and the second switch. The actuator can be used in common.

  According to the present invention, the forward and backward operations of the moving element can be distinguished and detected, and the amount of operation can be detected, the number of parts can be reduced, the configuration can be simplified, and the cost can be reduced. .

For example, three portions of the inner surface of the support cylinder portion 5 extend in the vertical direction (axial direction) and have guide grooves therebetween. Guide ribs 5a and 5a forming 5b are formed.

In the center of the bottom of the support cylinder 5, a setting start switch 6 comprising a tact switch, for example, is disposed.

In this case, for example, three guide ribs 7a extending in the vertical direction are formed on the outer periphery of the operation element 7, and the guide ribs 7a are fitted in the guide groove 5b so as to be movable up and down. The guide and the rotation stop. Note that a letter “A / C” is formed above the operation element 7 to indicate an air conditioner. Further, a pressing portion 7 b for operating the switch 6 is formed at the center of the operation element 7.

  Further, a cylindrical moving element 8 having a circular planar shape is movably fitted to the outer periphery of the supporting cylinder portion 5 in this case so as to be rotatable. The upper part of the operating element 7 faces the outside from the upper opening of the moving element 8, and the operating element 7 can be pressed.

  A large number of rod-like actuators 9 are arranged at predetermined intervals along the moving direction of the moving element 8 (the direction of arrows A and B in FIGS. 2 and 3). Each actuator 9 is provided so as to protrude in a direction (in this case, a radial direction) substantially orthogonal to the moving direction.

  The base body 3 is provided with a first switch actuating body 10 which can move and in this case can swing. In other words, the first switch operating body 10 has a shaft portion 10a at one end portion, a first inclined plate portion 10b at the upper portion of the other end portion, and a slightly convex portion at the lower portion of the other end portion. A first switch operation unit 10c having a shape is provided.

  The shaft portion 10a is swingably supported by bearing ribs 3a and 3a formed on the base body 3. The first inclined plate portion 10b can intersect the movement locus K (rotation locus) of the actuator 9, and is inclined in a predetermined direction (for example, the upper left direction as shown in FIGS. 4 and 5). Is formed.

  In addition, the base body 3 is provided with a first switch 11 that is positioned below the first switch operation unit 10c, which is in the vicinity of the first switch operating body 10. The first switch 11 is a tact switch.

  Further, the base body 3 is provided with a second switch operating body 12 that is symmetrical with the first switch operating body 10 in a left-right symmetrical arrangement with the first switch operating body 10. Is provided. The second switch actuating body 12 is also movable and in this case is swingable. That is, the second switch operating body 12 has a shaft portion 12a at one end portion, a second inclined plate portion 12b at the upper portion of the other end portion, and a slightly convex portion at the lower portion of the other end portion. A second switch operation unit 12c having a shape is provided.

  The shaft portion 12a is swingably supported by bearing ribs 3b and 3b formed on the base body 3. The second inclined plate portion 12b can intersect a movement locus K (rotation locus) of the actuator 9, and is in a direction opposite to the predetermined direction (for example, an upper right direction as shown in FIGS. 4 and 5). It is formed to be inclined.

  Further, the base body 3 is provided with a second switch 13 located below the second switch operation portion 12c, which is in the vicinity of the second switch operating body 12. The second switch 13 is also a tact switch.

  The panel plate 4 is formed with an opening 4a for allowing the moving element 8 to be exposed to the outside, and a cylindrical portion 4b extending downward from the peripheral edge of the opening 4a. Further, shaft pressing ribs 4c and 4d are formed at portions facing the bearing ribs 3a and 3b, and an attachment hole portion 4e corresponding to the attachment claw portion 3c formed in the bail body 3 is formed. A display unit 14 for displaying a set temperature is provided around the opening 4a.

  Now, the operation of the above configuration will be described. When the user rotates the moving element 8 in the forward direction (arrow A direction), for example, the operating element 9 rotates integrally in the forward direction, and the one surface portion of the first inclined plate portion 10b of the first switch operating body 10 is rotated. A certain upper surface portion 10J encounters relative to the actuator 9 and is pressed downward. As a result, the first switch operating body 10 rotates in one direction (the direction indicated by the arrow 10I), and the first switch operation unit 10c moves in one direction (the direction indicated by the arrow 10I). As a result, the first switch 11 is pressed and turned on. That is, the number of ON operations of the first switch 11 is the number of encounters of the actuator 9 with respect to the inclined plate portion 10b, and accordingly, the first switch 11 is a number corresponding to the amount of rotation that is the amount of movement of the movable member 8. Operate. Therefore, the forward rotation of the moving element 8 can be detected by the ON operation of the first switch 11 and the amount of movement can be detected by the number of ON operations of the first switch 11.

  At the time of turning in the forward direction, as shown in FIG. 4, the second switch operating body 12 has a lower surface portion 12K which is the other surface portion of the second inclined plate portion 12b. Thus, the second switch 13 is not turned on by moving (pushing up) in the other direction (the direction indicated by the arrow 12T).

  Conversely, when the moving element 8 is rotated in the backward direction (arrow B direction), as shown in FIG. 5, the actuator 9 is integrally rotated in the backward direction, and the second inclination of the second switch operating body 12. The upper surface portion 12J which is one surface portion of the plate portion 12b encounters the actuator 9 relatively and is pressed downward. As a result, the second switch operating body 12 rotates in one direction (the direction indicated by the arrow 12I), and the second switch operation unit 12c moves in one direction (the direction indicated by the arrow 12I). As a result, the second switch 13 is pressed and turned on. That is, the number of ON operations of the second switch 13 is the number of encounters of the actuator 9 with respect to the inclined plate portion 12b, and thus the second switch 13 is a number corresponding to the amount of rotation that is the amount of movement of the movable member 8. Operate. Accordingly, the backward rotation of the moving element 8 can be detected by the ON operation of the second switch 13 and the amount of movement can be detected by the number of ON operations of the second switch 13.

  At the time of turning in the backward direction, as shown in FIG. 5, the first switch operating body 10 has a lower surface portion 10 </ b> K that is the other surface portion of the first inclined plate portion 11 b relative to the actuator 9. Thus, the first switch 11 is not turned on by moving (pushing up) in the other direction (the direction indicated by the arrow 10T).

  As described above, the actuator 9 operates the first switch operating body 10 and the second switch operating body 12 in both the forward and backward rotations of the moving element 8, and consequently the first switch operating body 12. The switch 11 and the second switch 13 are operated, and the actuator 9 can be commonly used for detection in any direction.

  As described above, according to the present embodiment, the forward and backward rotation operations of the moving element 8 can be distinguished and detected, and the operation amount can be detected, and the number of parts can be reduced and the configuration can be reduced. It becomes easy and can reduce the cost.

  Further, according to the present invention, the actuator 9 is configured to protrude in a bar shape, and the first switch operating body 10 can intersect the movement locus of the actuator 9 and incline in a predetermined direction. 10b and a first switch operation portion 10c, and a second inclined plate portion that can cross the movement locus of the actuator 9 and incline the second switch actuator 12 in the direction opposite to the predetermined direction. 12b and the second switch operation unit 12c, the configuration can be further simplified, and in particular, the configuration of the actuator 9 can be simplified.

Further, according to the present embodiment, since the movable element 8 is configured to rotate and move in the forward direction and the backward direction, it is suitable as a rotary switch device.
Furthermore, according to the present embodiment, since the first switch 11 and the second switch 13 are constituted by tact switches, the first switch actuating body 10 and The second switch actuating body 12 can be returned to the original position, and the actuating body returning spring means can be omitted.

  In the above embodiment, the rotary switch device 1 is configured by providing the movable element 8 so as to rotate in the forward direction and the backward direction. However, the rotary switch device 1 may be configured as shown in FIG. That is, FIG. 6 shows a second embodiment of the present invention, and shows a slide switch device 22 configured to move the moving element 21 linearly. In this way, in the slide switch device 22, the forward and backward operations of the mover 21 can be distinguished and detected, and the operation amount can be detected, and the number of parts can be reduced and the configuration is simple. Thus, the cost can be reduced. In addition, the present invention is not limited to the above-described embodiments. For example, the actuator may not be a rod shape, but may be a thin rib shape, for example. Further, the present invention can be applied to devices other than a switch device for setting the temperature of an air conditioner such as a vehicle.
