Description

Stoke switch

The present invention relates to a Stoke switch.

Normally, stalk switches such as direction indicator lamps and wiper switches are installed on both sides below the steering of the car. The Stoke switch is configured by a combination of a peristaltic lever switch and a knob switch, and different functions are realized by performing different operations on the peristaltic lever switch and the knob switch. Taking the direction indicator lamp switch on the lower left side of the steering wheel as an example, for example, by turning the direction indicator lamp switch up and down, the function to turn on and off the left and right turn signal lamps is realized. The function of turning on / off the high beam lamp is realized by peristaltic movement, and the function of turning on / off the head lamp, tail lamp, etc. is realized by rotating the rotary switch.

FIG. 1 is a perspective view showing a conventional stalk switch 1. FIG. 2 is an exploded perspective view showing the Stoke switch 1 in FIG.

The outer shape of the stalk switch 1 in FIG. 1 is substantially rod-shaped. Mainly, a rod-shaped lever body 2 located on the center side, a cylindrical operation knob 3 located on the outside, and between the lever body 2 and the operation knob 3. The operation knob 3 and the rotation cam 4 can be integrally rotated with respect to the lever main body 2. The lever body 2 is further provided with a circuit board 5, which can convert an operation on the stalk switch 1 into a control signal corresponding to each operation and transmit it to a control mechanism (not shown).

The lever body 2 is provided with a recess 2a extending in the circumferential direction, and the rotary cam 4 is provided with a first protrusion 4a that engages with the recess 2a and protrudes toward the recess 2a. . In a state where the recess 2a is engaged with the first protrusion 4a, the rotating cam 4 cannot move along the longitudinal direction of the lever body 2, and the relative position of the rotating cam 4 in the longitudinal direction of the lever body 2 is fixed. Is done.

The rotary cam 4 is further provided with a substantially rectangular hole 4b, and the operation knob 3 is further provided with a second protrusion 3a that engages with the hole 4b and protrudes toward the hole 4b. ing. When the hole 4b is engaged with the second protrusion 3a, the operation knob 3 cannot move along the longitudinal direction of the lever body 2, and the relative position of the operation knob 3 in the longitudinal direction of the lever body 2 is Fixed.

Further, the outer wall of the rotating cam 4 is further provided with a third protrusion 4c that protrudes outward, and the inner wall of the operation knob 3 is further provided with a recess 3b that engages with the third protrusion 4c. In a state where the third protrusion 4c is engaged with the recess 3b, the operation knob 3 cannot move along the circumferential direction of the rotary cam 4, and the relative position of the operation knob 3 in the circumferential direction of the rotary cam 4 Is fixed.

However, in the conventional stalk switch 1 shown in FIGS. 1 and 2, the first protrusion 4a and the hole 4b provided on the rotating cam 4 are provided at different positions, so that the surface area of the rotating cam 4 is reduced. The usage rate is low, and the degree of freedom in installing other functional mechanisms, marks, etc. on the rotating cam 4 is low. Further, if the first protrusion 4a and the hole 4b are simply placed close to each other, there are too many holes in the local area, so that the strength of the rotating cam 4 may be lowered.

An object of the present invention is to provide a stalk switch that can improve the usage rate of the surface area of a rotating cam.

In one aspect of the embodiment of the present invention, the stalk switch is provided on both sides below the steering, and is a rod-shaped lever body, a substantially cylindrical operation knob located outside the lever body, the lever body, and the A substantially cylindrical rotating cam positioned between the operating knob and the operating knob and the rotating cam, wherein the operating knob and the rotating cam can rotate integrally with respect to the lever body, the longitudinal direction of the lever body A first engagement mechanism that restricts a relative position between the lever main body and the rotary cam in a second engagement mechanism that restricts a relative position between the operation knob and the rotary cam in the longitudinal direction of the lever main body; The first engagement mechanism and the second engagement mechanism share a partial area in the peripheral wall of the rotating cam.

According to one aspect of the embodiment of the present invention, the first engagement mechanism and the second engagement mechanism share a partial region in the peripheral wall of the rotating cam, that is, the first engagement mechanism and the second engagement mechanism. Is partially overlapped on the peripheral wall of the rotating cam, and the space occupied by the first engagement mechanism and the second engagement mechanism is reduced as compared with the conventional case where the first engagement mechanism and the second engagement mechanism are provided apart from each other. And the usage rate of the surface area of the rotating cam can be improved. As a result, it is possible to improve the degree of freedom in installing other functional mechanisms, marks, and the like on the rotating cam.

It is a perspective view of the rotating cam seen from another angle. It is a perspective view of the operation knob seen from another angle. It is a fragmentary sectional view of a Stoke switch.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS.

FIG. 3 is a perspective view of the stalk switch 10 of the present invention. 4 to 6 are exploded perspective views of the stalk switch 10 in FIG. FIG. 7 is a partial cross-sectional view of the Stoke switch 10.

As shown in FIGS. 3 and 4, the stalk switch 10 mainly includes a rod-shaped lever body 20, a substantially cylindrical operation knob 30 positioned outside the lever body 20, and between the lever body 20 and the operation knob 30. The operation knob 30 and the rotation cam 40 can be integrally rotated with respect to the lever body 20. The lever body 20 further holds a circuit board 50. The circuit board 50 converts an operation on the stalk switch 10 into a control signal corresponding to each operation and transmits the control signal to a control mechanism (not shown).

The lever body 20, the operation knob 30 and the rotating cam 40 are all made of synthetic resin. The substantially cylindrical rotating cam 40 surrounds the outside of the lever body 20, and the substantially cylindrical operating knob 30 surrounds the outside of the rotating cam 40. As shown in FIGS. 5 and 6, the side wall of the operation knob 30 and the side wall of the rotary cam 40 are provided with irregular functional mechanisms such as holes and openings, and are therefore referred to as “substantially cylindrical”.

As shown in FIGS. 3 and 7, the first end (right end in FIG. 4) 41 of the rotating cam 40 contacts the contact portion 21 of the lever body 20, and the second end (left end in FIG. 4) of the rotating cam 40. The lever body 20 is engaged by a first engagement mechanism described later. Thereby, the relative position of the rotary cam 40 in the longitudinal direction of the lever main body 20 is fixed, and the rotary cam 40 can be rotated around the lever main body 20. In this specification, the longitudinal direction of the lever body 20 is a direction substantially parallel to the central axis (that is, the rotation axis) of the rotary cam 40 and the operation knob 30.

As shown in FIG. 4, the first engagement mechanism includes a recess 22 provided in the lever main body 20 and a first protrusion 42 provided in the rotary cam 40 and engaged with the recess 22. The recess 22 is formed extending along the circumferential direction of the lever body 20. Thereby, when the 1st projection part 42 is engaged with the recessed part 22, as shown in FIG. 7, the rotation cam 40 can rotate along the extension direction (circumferential direction) of the recessed part 22. As shown in FIG. However, the relative position of the rotary cam 40 in the longitudinal direction of the lever body 20 is fixed.

FIG. 5 is a perspective view of the rotating cam 40 viewed from another angle. A substantially rectangular hole 43 is provided on the peripheral wall of the rotating cam 40, and the extending direction of the two long sides (the first long side 43 a and the second long side 43 b) of the hole 43 is the center axis of the rotating cam 40. The one short side (first short side 43c) of the hole 43 is connected to the root part 42a of the first protrusion 42, and the other short side (second short side 43d) is connected to the first direction. There is a certain gap between the tip 42 b of the protrusion 42. In addition, the substantially rectangular shape of the hole 43 means a shape in which two right angles on the second short side 43d side are chamfered.

Further, as shown in FIGS. 4 and 7, the first protrusion 42 is formed to extend from the root 42a to the tip 42b while being inclined toward the central axis. Further, a protrusion 42c that protrudes toward the lever body 20 is formed at the tip 42b of the first protrusion 42. Thereby, when attaching the rotation cam 40 to the lever main body 20, the front end portion 42 b of the first protrusion 42 can be engaged with the recess 22 without applying a force to the lever main body 20 to the first protrusion 42. (See FIG. 7).

As shown in FIG. 4, a first pentagonal convex portion 44 and a long second convex portion 45 are provided in the vicinity of the first end 41 (the right end in FIG. 4) of the rotating cam 40, and the operation knob 30. The first end 31 is provided with a first opening 33 that engages with the first protrusion 44 and a second opening 34 that engages with the second protrusion 45. When the first convex portion 44 and the second convex portion 45 engage with the first opening 33 and the second opening 34, respectively, the first end 31 of the operation knob 30 and the first end 41 of the rotating cam 40 are The operation knobs 30 are brought into contact with each other, and the operation knob 30 cannot move to the first end 41 side of the rotary cam 40 (the state shown in FIG. 3).

Further, the second end (the left end in FIG. 4) of the rotating cam 40 is engaged with the lever main body 20 by the second engaging mechanism, and the second engaging mechanism includes the hole 43 provided in the rotating cam 40, and the operation knob. 30 and has a second protrusion 32 that engages with the hole 43. As shown in FIG. 7, the second protrusion 32 has a protrusion 32 a that protrudes toward the rotating cam 40, and the protrusion 32 a includes the second short side 43 d of the hole 43 and the tip 42 b of the first protrusion 42. The protrusion 32a can be engaged with the second short side 43d. Thereby, the position of the operation knob 30 in the longitudinal direction of the lever body 20 can be fixed, and the operation knob 30 can be rotated around the lever body 20 together with the rotary cam 40 in the circumferential direction.

As shown in FIG. 6, the inner wall of the operation knob 30 has four ribs (first rib 35 and second rib 36) extending along the direction of the central axis of the operation knob 30 and projecting inward. , Third ribs 37 and fourth ribs 38) are provided. Four concave grooves corresponding to the first rib 35, the second rib 36, the third rib 37, and the fourth rib 38 (corresponding to the first rib 35 in FIGS. 4 and 5) are formed on the outer wall of the rotating cam 40, respectively. Only the second concave groove 47 corresponding to the first concave groove 46 and the second rib 36 is shown).

The engagement between the operation knob 30 and the rotating cam 40 is brought closer due to the engagement between the ribs and the concave grooves. Therefore, noise is generated due to vibration generated between the operation knob 30 and the rotating cam 40. Or the feeling of operation of the operation knob 30 can be avoided.

As shown in FIG. 5, in the peripheral wall of the rotating cam 40, the first protrusion 42 is located inside the region surrounded by the four sides of the hole 43, and the first protrusion 42 and the hole 43 are combined. The engaging part is constituted.

In the stalk switch 10 of the present embodiment, the first engagement mechanism and the second engagement mechanism share a partial region in the peripheral wall of the rotating cam 40, that is, the first engagement mechanism and the second engagement. Since the mechanism partially overlaps on the peripheral wall of the rotating cam 40, the first engagement mechanism and the second engagement mechanism are different from the conventional case where the first engagement mechanism and the second engagement mechanism are provided apart from each other. The occupied space can be reduced, and the usage rate of the surface area of the rotating cam 40 can be improved. As a result, it is possible to improve the degree of installation freedom when installing other functional mechanisms, marks, and the like on the rotating cam 40. Further, as compared to the case where the first protrusion 4a and the hole 4b shown in FIG. 2 are provided apart from each other, the dual engagement portion can be realized by installing only one hole in the rotating cam 40. It is possible to avoid a decrease in strength due to too many holes in the local area.

Further, in the stalk switch 10 of this embodiment, the cylindrical rotary cam 40 is provided with two dual-purpose engaging portions. Thereby, the engagement state of the lever main body 20 and the rotation cam 40 and the engagement state of the rotation cam 40 and the operation knob 30 can be further stabilized.

In the Stoke switch 10 of the present embodiment, the two

long sides

43a and 43b of the hole 43 are substantially parallel to the central axis of the cylindrical rotating cam 40. The first protrusion 42 is formed in a substantially rectangular shape, and has a root portion 42 a that is connected to the first short side 43 c of the hole 43. The first protrusion 42 extends inside the hole 43 along the direction of the

long sides

43a and 43b of the hole 43 from the base 42a toward the second short side 43d. A protrusion 42 c is formed at the tip 42 b of the first protrusion 42. There are gaps between the first protrusion 42 and the second short side 43d of the hole 43 and the two

long sides

43a and 43b. The second protrusion 32 engages with the second short side 43 d of the hole 43, and at least a part of the second protrusion 32 (part of the protrusion 32 a) is formed between the tip 42 b of the first protrusion 42 and the hole 43. It can be accommodated in a gap between the second short side 43d. The first protrusion 42 and the second protrusion 32 protrude toward the lever body 20 side.

As a result, the

long sides

43a and 43b of the hole 43 are substantially parallel to the central axis of the cylindrical rotating cam 40, and the two

short sides

43c and 43d of the hole 43 are rationally used, so that the first protrusion The engagement between the portion 42 and the recess 22 and the engagement between the second protrusion 32 and the hole 43 are realized. For this reason, the length of the short side of the hole 43 is the length that the dual-purpose engaging portion occupies on the circumference of the rotating cam 40. When it is necessary to install a functional mechanism such as a concave groove or a rib extending along the central axis direction of the rotating cam 40 in the rotating cam 40, out of the circumferential length of the rotating cam 40, Since it should just install in parts other than the part which overlaps with a short side, the installation freedom degree of these functional mechanisms can be improved.

Especially, in the design of a specific vehicle, the external surface of the stalk switch 10 is severely limited, and the outer diameter and thickness of the operation knob 30 become thinner and thinner. In this case, in order to maintain the strength of the operation knob 30, it is preferable to provide a plurality of ribs on the inner wall of the operation knob 30 and provide a plurality of concave grooves on the outer wall of the rotating cam 40 as in this embodiment. Moreover, it is preferable to leave as much installation space as possible in the circumferential direction of the operation knob 30 to improve the degree of freedom of installation of these functional mechanisms.

(Modification)
The present invention is not limited to the above-described preferred embodiments, and those skilled in the art may make various changes, combinations, and substitutions to the components of the above-described embodiments within the technical scope or equivalent scope of the present invention. .

For example, the number of dual-purpose engaging portions may be one or three or more. Moreover, it is preferable that a plurality of dual-purpose engaging portions are arranged at equal intervals in the circumferential direction of the rotating cam 40. For example, when two dual-purpose engaging portions are provided, the two dual-purpose engaging portions are preferably arranged symmetrically with respect to the central axis of the cylindrical rotating cam 40.

The shape of the hole 43 is not limited thereto, and for example, a structure in which the short side of the substantially rectangular hole 43 is substantially parallel to the central axis of the rotating cam 40 may be used. The length of the long side of the hole 43 is the length occupied on the circumference of the rotating cam 40 of the dual-purpose engaging portion. At this time, the length of the short side of the hole 43 is the length occupied in the central axis direction of the rotary cam 40 of the dual-purpose engaging portion. Thereby, the freedom degree which installs another functional mechanism in the central-axis direction of the rotating cam 40 can be improved.

(Appendix)
In one aspect of the embodiment of the present invention, the stalk switch is provided on both sides below the steering, and is a rod-shaped lever body, a substantially cylindrical operation knob located outside the lever body, the lever body, and the A substantially cylindrical rotating cam positioned between the operating knob and the operating knob and the rotating cam, wherein the operating knob and the rotating cam can rotate integrally with respect to the lever body, the longitudinal direction of the lever body A first engagement mechanism that restricts a relative position between the lever main body and the rotary cam in a second engagement mechanism that restricts a relative position between the operation knob and the rotary cam in the longitudinal direction of the lever main body; The first engagement mechanism and the second engagement mechanism may share a partial area in the peripheral wall of the rotating cam.

Thus, the first engagement mechanism and the second engagement mechanism share a partial area on the peripheral wall of the rotating cam, that is, the first engagement mechanism and the second engagement mechanism are partially on the peripheral wall of the rotary cam. The space occupied by the first engagement mechanism and the second engagement mechanism can be reduced as compared to the case where the conventional first engagement mechanism and the second engagement mechanism are provided apart from each other, and the usage rate of the surface area of the rotating cam is reduced. Can be improved. As a result, it is possible to improve the degree of freedom in installing other functional mechanisms, marks, and the like on the rotating cam.

The first engagement mechanism includes a recess provided in the lever main body, and a first protrusion provided in the rotary cam and engaged with the recess. The second engagement mechanism includes A substantially rectangular hole provided in the rotary cam, and a second protrusion provided in the operation knob and engaged with the hole. The protrusion may be located inside a region surrounded by the four sides of the hole, and the first protrusion and the hole may constitute a combined engagement portion.

As a result, when the first protrusion is located inside the region surrounded by the four sides of the hole, the conventional first protrusion and the hole are provided independently, and it is necessary to open the holes separately. As compared with the above, by installing only one hole in the rotating cam, it is possible to realize the dual-purpose engaging portion, and it is possible to avoid a decrease in strength due to too many holes in the local portion.

Further, two or more dual-purpose engaging portions may be provided on the rotating cam.

Thus, by providing two or more dual-purpose engaging portions, it is possible to further stabilize the engaged state between the lever body and the rotating cam and the engaged state between the rotating cam and the operation knob.

The long side of the hole is substantially parallel to the central axis of the rotating cam, and the first protrusion has a root portion connected to one short side of the hole, and the hole extends from the root to the hole. Extending toward the other short side of the portion, and there is a gap between the first protrusion and the other short side and the two long sides of the hole, and the tip of the first protrusion A protrusion may be formed on the portion.

The second protrusion is engaged with the other short side of the hole, and at least a part of the second protrusion is formed between the tip of the first protrusion and the other of the holes. It may be accommodated in a gap between the short sides.

The first protrusion and the second protrusion may protrude toward the lever body.

By this, the long side of the hole is substantially parallel to the central axis of the cylindrical rotating cam, and the two short sides of the hole are rationally used, so that the engagement between the first protrusion and the recess and the first The engagement between the two protrusions and the hole is realized. For this reason, the length of the short side of the hole is the length that the combined engagement portion occupies on the circumference of the rotating cam. When it is necessary to install a functional mechanism such as a groove or rib extending along the central axis direction of the rotating cam, the rotating cam overlaps the short side of the hole in the circumferential length of the rotating cam. Since it should just install in parts other than a part, the freedom degree of installation of these functional mechanisms can be improved.

Although the Stoke switch has been described in the above embodiments and examples, the present invention is not limited to the above embodiments and examples. Various modifications and changes are possible within the scope of the gist of the present invention described in the claims.
