  Embodiments of the swing switch unit of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a perspective view of an operation unit 100 provided with a swing switch unit 1 according to the present invention. The operation unit 100 includes, for example, a well-known haptic device 101 of a joystick or a slider type that is provided at a center console of a vehicle, and the swing switch unit 1 (two in FIG. 1) is a haptic. It can be operated in cooperation with the device 101 or independently. There are no particular restrictions on the mounting position of the swing switch unit 1 or on-vehicle equipment (navigation device, air conditioner, etc.) that is the target of operation using the swing switch unit 1.

  FIG. 2 is an exploded perspective view of the swing switch unit 1, and FIG. 3 is a perspective view of the swing switch unit 1 with the swing switch knob 10 removed. The swing switch unit 1 covers a housing 50 assembled to the operation unit 100 or formed integrally with the operation unit 100, and an opening 55 (see FIG. 4) at the top of the housing 50, for example, rubber. A seal member 20 made of an elastic member such as a thermoplastic elastomer is attached by the elastic force, and a seal member 20 for preventing liquid such as water from entering the inside of the housing 50, and a swing switch And a knob 10. Further, upper end portions 31 a and 31 b of the urging transmission bodies 30 a and 30 b (see FIG. 10) are inserted through the seal member 20.

  FIG. 4 shows an example of the opening 55 formed in the upper part of the housing 50. A support 53 for projecting in the direction of the opening forming surface and supporting the seal member 20 (for example, a region indicated by 64 in FIG. 9) is formed at the peripheral edge of the opening 55. Thereby, the deformation | transformation at the time of mounting | wearing of the sealing member 20 can be prevented, the sealing member 20 can be reliably mounted | worn to the housing | casing 50, and waterproofness can be improved more. Moreover, dustproofness can also be improved.

  Hereinafter, the configuration of the swing switch unit 1 will be described in detail with reference to FIG. FIG. 10 shows an XX cross section when the swing switch knob 10 is assembled in FIG.

  The swing switch unit 1 includes a housing 50 made of, for example, ABS resin, and an engagement convex portion 51 serving as a swing fulcrum provided in the housing 50 in both directions on the engagement hole 12 (see FIG. 14). And a pair of tact switches 40a and 40b that constitute push-type switch elements provided corresponding to the swinging ends 11a and 11b of the swinging switch knob 10; The swing switch knob 10 is provided so as to be swingable in both directions. As one swing end 11a, 11b of the swing switch knob 10 is pressed and biased, the pressing biasing force is applied to the tact switch. And urging transmission bodies 30a and 30b that transmit to 40a and 40b. Thus, as the pressing operation is applied to the swinging ends 11a and 11b in the swinging longitudinal direction of the swinging switch knob 10, the corresponding urging transmission bodies 30a and 30b approach toward the corresponding tact switches 40a and 40b. Oscillating displacement in the direction.

  As shown in FIGS. 13 and 14, the swing switch knob 10 is a knob having a hollow flange shape having a design surface formed on the front side in the pressing and biasing operation direction and opening rearward in the pressing and biasing operation direction. On the inside of the main body 13 and the knob main body 13, the rocking ends 11 a and 11 b formed to protrude in the pressing and biasing operation direction with a predetermined interval in the rocking longitudinal direction, and the knob body 13 in the rocking longitudinal direction An engagement hole portion 12 that is swingably assembled to the engagement convex portion 51 of the housing is provided at an intermediate position on the side surface, and is formed as a resin injection molded body made of ABS resin. Further, when one of the swinging ends 11 a and 11 b of the swinging switch knob 10 is pressed and urged, the swinging switch knob 10 is swingingly displaced while being in contact with the swinging guide portion 52 formed in the housing 50. Further, regions 14a and 14b are in contact with the swing guide portion 52.

  Returning to FIG. 10, the urging transmission bodies 30 a and 30 b are formed as, for example, resin injection molded bodies made of ABS resin. As shown in FIG. 20, the urging transmission body 30a includes a main body 33a having a substantially comb-shaped cross section and a rectangular parallelepiped with one vertical surface opened, and a swing switch knob from the main body 33a. The upper end portion 31a protrudes toward the rocking end 11a and has a substantially cylindrical shape, and the lower end portion 32a protrudes from the main body portion 33a toward the tact switch 40a and has a substantially cylindrical shape (also about 30b). The same). FIG. 10 shows a cross-sectional view seen from the YY direction in FIG.

  The portions of the top ends 31a and 31b that are in contact with the rocking ends 11a and 11b are also substantially cylindrical, but in order to reliably transmit the pressing biasing force of the rocking ends 11a and 11b (for example, rocking) Other shapes such as a polygonal column shape (according to the shapes of the moving ends 11a and 11b) may be used. Moreover, although the front-end | tip of lower end part 32a, 32b becomes substantially taper shape, in order to transmit a pressing biasing force to corresponding tact switch 40a, 40b reliably, it is the substantially cylindrical shape similar to upper end part 31a, 31b. It is good also as such other shapes.

  The urging transmission bodies 30a and 30b are formed to extend toward the corresponding tact switches 40a and 40b to urge the tact switches 40a and 40b, and the upper end portions 31a and 31b are provided with the swing switch knob 10. Are arranged in contact with the corresponding swinging ends 11a and 11b, or with a predetermined gap. Further, the lower end portions 32a and 32b are arranged so as to be always in contact with the tip portions 41a and 41b of the tact switches 40a and 40b, or provided with a predetermined gap.

  The tact switches 40a and 40b correspond to the swinging ends 11a and 11b of the swinging switch knob 10 and are provided at the rear end of the operation pressing direction. (Direction) at a predetermined interval, and the continuity state is switched by pressing and releasing the urging ends 11 a and 11 b of the oscillating switch knob 10. The tact switches 40a and 40b generate an operational moderation feeling (click feeling) as the tip portions 41a and 41b having pressing operation surfaces are pressed and urged.

  The configuration of the seal member 20 will be described with reference to FIGS. FIG. 5 is a perspective view of the seal member 20 (the reference numerals are partially omitted), FIG. 6 is a top view and a side view corresponding to the swing switch knob 10 side of the seal member 20, and FIG. 7 is a front view of the seal member 20 8 is a cross-sectional view taken along line AA in FIG. 6, and FIG. 9 is a bottom view corresponding to the tact switch 40a, 40b side of the seal member 20 and a cross-sectional view taken along line BB.

  The seal member 20 is formed with substantially circular through holes 21a and 21b through which the upper end portions 31a and 31b of the urging transmission bodies 30a and 30b are inserted, and the upper end portions 31a and 31b are the elastic force of the seal member 20. Is in contact.

  The region 25 including the through holes 21a and 21b is thinner than the other regions 24a and 24b. That is, it becomes thinner intermittently as it approaches the through holes 21a and 21b. A change in thickness from the regions 24a and 24b to the region 25 (or the through holes 21a and 21b) may be continuously thinned as a slope shape. As a result, the strength of the seal member 20 is sufficient, and the elastic deformation of the peripheral portions 29a and 29b of the through holes is made easier (details will be described later).

  Further, on the upper surface of the seal member 20, there are provided upper surface convex portions 22a and 22b which are pressed and urged by the protrusion portions 13a and 13b (see FIGS. 13 and 14) of the swing switch knob 10 (operation and action). Will be described later). Moreover, the upper surface connection convex part 23 which connects the upper surface convex parts 22a and 22b is also formed, and has comprised the substantially H shape. As a result, the strength of the seal member 20 becomes sufficient, and the elastic urging force in the direction of the periphery (for example, the swinging guide portion 52) of the opening 55 of the housing 50 of the upper surface convex portions 22a and 22b is further increased. The mounting of the seal member 20 to the housing 50 is ensured.

  Further, the seal member 20 is formed with recesses 27a and 27b, and the swing guide portion 52 formed in the housing 50 is connected to the seal member 20 (for example, the upper surface protrusions 22a and 22b and the upper surface connection protrusion 23). It is mounted with an elastic biasing force. Thus, by mounting the seal member 20 so as to surround the three sides of the swing guide portion 52, the seal member 20 can be securely mounted to the housing 50 without being loose.

  In addition, although the notch part 26 is formed in each vertex of the substantially rectangular seal member 20, it is good also as a structure without these notch parts. Further, since the notch 26 is formed, interference between the swing switch knob 10 and the seal member 20 can be reduced, and the movable range of the swing switch knob 10 can be widened.

  In particular, in FIGS. 7 to 9, lower surface convex portions 61 a, 61 b, 62 a, and 62 b are formed on the lower surface of the seal member 20 for surely mounting on the housing 50. Further, a lower surface connection convex portion 63 that connects the lower surface convex portions 62a and 62b is also formed, and has a substantially H shape. Thereby, the strength of the seal member 20 is made sufficient, and the elastic urging force in the peripheral direction of the opening 55 of the casing 50 of the lower surface convex portions 62a and 62b is further increased. And these lower surface convex parts 61a and 61b are inserted in the space 55a and 55c (refer FIG. 4) which the support part 53 and the periphery of the housing | casing 50 form, and the lower surface convex parts 62a and 62b are two support. By being inserted into the spaces 55b and 55d (see FIG. 4) between the portions 53, the seal member 20 is securely attached to the housing 50 with the elastic biasing force of each member.

  The details of the through holes 21a and 21b of the seal member 20 will be described with reference to FIGS. 11 and 12 by taking a sectional view of the through hole 21a as an example. As shown in FIG. 11 (as in the cross-sectional view of FIG. 9), the peripheral edge 29a of the through hole 21a is directed toward the operation switch knob 10 (that is, pressed) compared to the other parts of the seal member 20. A projecting portion that projects continuously or intermittently toward the circumferential direction of the through hole 21a in a form in which the diameter of the hole continuously or intermittently shrinks (or the direction opposite to the direction in which the force is transmitted) is formed. Part). The peripheral edge portion 29a is in contact with the upper end portion 31a of the urging transmission body 30a inserted through the through hole 21a with elasticity. Thereby, the play of the urging | biasing transmission body 30a can also be suppressed.

  As shown in FIG. 12, when a pressing operation is applied to the swing end 11a of the swing switch knob 10, the upper end portion 31a of the urging transmission body 30a moves in the direction of the tact switch 40a. At this time, the seal member is configured so that the frictional force generated on the contact surface P between the urging transmission body 30a (end portion 31a) and the peripheral edge portion 29a is larger than the pressing urging force applied to the urging transmission body 30a. By selecting the material of 20 and the urging transmission body 30a, the peripheral edge portion 29a is elastically deformed while maintaining a contact state without sliding on the upper end portion 31a. Thereby, it can prevent that a space | gap arises between the peripheral part 29a and the upper end part 31a, and impairs waterproofness.

  FIG. 13 shows a schematic diagram of the inside (lower side) of the swing switch knob 10. FIG. 14 shows a side view of the swing switch knob 10. On the inner side (lower side) of the swing switch knob 10, projections 13a and 13b for pressing and urging the upper surface convex portions 22a and 22b of the seal member 20 are provided. FIG. 15 shows a longitudinal sectional view of the swing switch knob 10 around the protrusion 13a. In FIG. 15, the housing 50 is omitted. As described above, the pressing biasing force is constantly applied from the swing switch knob 10 to the seal member 20, so that the mounting of the seal member 20 to the housing is ensured. Of course, this pressing biasing force does not affect the operation of the swing switch knob 10.

  When one of the oscillating ends 11a and 11b of the oscillating switch knob 10 is pressed and biased, the corresponding upper surface convex portions 22a and 22b are further elastically deformed in the direction pressed by the projecting portions 13a and 13b (FIG. 16). (When the rocking end 11a is pressed). When the rocking ends (11a, 11b) are no longer pressed and biased, the rocking switch knob 10 returns to the original position (neutral position) by the restoring force at the time of elastic deformation of the upper surface convex portions 22a, 22b.

  Further, the swing switch knob 10 (projections 13a and 13b) is attached to the housing 50 in a state of being pressed and urged by the convex portions 22a and 22b of the seal member. It is possible to suppress rattling at the time of pressing, vibration of the swing switch knob 10 during traveling of the vehicle, and noise generated by the vibration. Further, it is possible to make the user feel a moderate response.

  Another example of the embodiment of the swing switch unit 1 according to the present invention will be described with reference to FIG. In addition, since a present Example is a modification of the above-mentioned Example 1, it attaches | subjects the same code | symbol about the thing of the same structure, and omits detailed description here.

  As shown in the top view of FIG. 21, the seal member 201 covering the opening 55 has substantially the same configuration as the seal member 20 of the above-described embodiment, and the difference is that there are no through holes (21a, 21b). That is, the seal member 201 covers the entire surface of the opening 55 and prevents the intrusion of a liquid such as water.

  Moreover, the shape of the upper end portions 31a and 31b of the urging transmission bodies 30a and 30b may not be a columnar shape but may be a polygonal column shape.

  As shown in FIG. 17, the swinging ends 11 a and 11 b of the swinging switch knob 10 are arranged so as to be always in contact with the upper surface of the seal member 201 or with a predetermined gap. Further, the upper end portions 31a and 31b of the urging transmission bodies 30a and 30b are also arranged in a state in which they are always in contact with the lower surface of the seal member 201 or provided with a predetermined gap. Further, the thickness of the seal member 201 is such that the portion (25 in FIG. 21) where the swinging ends 11a and 11b and the upper end portions 31a and 31b abut is thinner than the other portions (24a and 24b in FIG. 21) ( That is, when the portions corresponding to the through holes 21a and 21b in FIG. 6 have the same thickness as the surroundings), the pressing biasing force from the swinging ends 11a and 11b is efficiently transmitted to the biasing transmission bodies 30a and 30b. Can do.

  If the rocking ends 11a and 11b of the rocking switch knob 10 are always in contact with the upper surface of the seal member 201, the vibration isolating is combined with the structure of the rocking switch knob 10 shown in FIGS.・ We can expect soundproofing effect. Further, if the upper end portions 31a and 31b of the urging transmission bodies 30a and 30b are arranged in a state where they are always in contact with the lower surface of the seal member 201, the same effect can be expected.

  In the above configuration, when one of the swinging ends 11a and 11b of the swing switch knob 10 is pressed and biased, the pressing biasing force is transmitted to the corresponding biasing transmission bodies 30a and 30b via the seal member 201. The lower end portions 32a and 32b of the urging transmission bodies 30a and 30b press and urge the tip portions 41a and 41b of the corresponding tact switches 40a and 40b.

  With reference to FIG. 18, another example of the embodiment of the swing switch unit 1 according to the present invention will be described. In addition, since a present Example is a modification of the above-mentioned Example 2, it attaches | subjects the same code | symbol about the thing of the same structure, and omits detailed description here.

  The difference from the second embodiment is that the seal member 202 is not the opening 55 at the upper end of the casing 50, but the opening surface between the urging transmission bodies 30a and 30b and the tip portions 41a and 41b of the tact switches 40a and 40b. It is attached to 54 by the elastic force. The seal member 202 covers the entire opening surface 54 and prevents the intrusion of a liquid such as water.

  Further, since the urging transmission bodies 30a and 30b are not inserted into the seal member 201, there are no upper end portions 31a and 31b, and the oscillating ends 11a and 11b of the oscillating switch knob 10 are the main body portions of the urging transmission bodies 30a and 30b. 33a and 33b are always in contact with each other, or are provided with a predetermined gap.

  Further, the lower end portions 32a and 32b of the urging transmission bodies 30a and 30b are arranged in a state where they are always in contact with the upper surface of the seal member 202, or provided with a predetermined gap. Further, the tip portions 41a and 41b of the tact switches 40a and 40b are arranged in a state in which they are always in contact with the lower surface of the seal member 202 or provided with a predetermined gap.

  In the above configuration, when one of the swinging ends 11a and 11b of the swing switch knob 10 is pressed and biased, the pressing biasing force is transmitted to the corresponding biasing transmission bodies 30a and 30b (main body portions 33a and 33b). The lower end portions 32a and 32b transmit the pressing biasing force to the corresponding tip portions 41a and 41b of the tact switches 40a and 40b via the seal member 202. The thickness of the seal member 202 is such that if the portions where the lower end portions 32a, 32b and the tip portions 41a, 41b abut are made thinner than the other portions, the pressing urging force from the urging transmission bodies 30a, 30b can be efficiently tacted. It can be transmitted to the switches 40a and 40b.

  Further, the elastic member 70 may be disposed between the upper portion of the seal member 202 and the urging transmission bodies 30a and 30b (main body portions 33a and 33b). The elastic member 70 is elastically pressed by the urging transmission body 30 when one of the oscillating ends 11a, 11b of the oscillating switch knob 10 is pressed and urged to move either of the urging transmission bodies 30a, 30b. Deform. When the rocking ends (11a, 11b) are no longer pressed and biased, the biasing transmission bodies 30a, 30b are pushed up by the restoring force at the time of elastic deformation, and the rocking switch knob 10 is returned to the original position (neutral position). .

  For comparison with the present embodiment, FIG. 19 shows a configuration example of the swing switch unit 1 according to the prior art. 18 is different from the example in FIG. 18 only in that the seal member 202 is not provided (some symbols are omitted for the same configuration). In the configuration of FIG. 19, when a liquid such as water enters the casing 50 from the upper part of the swing switch unit 1 (that is, near the swing switch knob 10), it is easy to reach the substrate 60 to which the tact switches 40a and 40b are attached. Will reach. On the other hand, in the example of FIG. 18, even when a liquid such as water enters the housing 50, the sealing member 202 can prevent the substrate 60 from reaching.

  In the example of FIG. 18, the seal member 202 also has an effect of absorbing vibrations of the urging transmission bodies 30 a and 30 b. Occurrence can also be prevented.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
