This is the structure it takes. [Effects of the Invention]
[0008] The present invention, configured as described above, provides a switch unit that can suppress a decrease in the detection accuracy of switch operations. [Brief explanation of the drawing]

[Figure 2] This figure shows the state when the switch unit disclosed in Figure 1 is assembled. [Figure 3] This diagram shows the configuration of the switch devices that make up the switch unit.

[Figure 8] This diagram shows how the switch device is assembled to the adjuster. [Modes for carrying out the invention]
[0010] <Embodiment 1> A first embodiment of the present invention will be described with reference to Figures 1 to 8. Figures 1 to 6 are diagrams illustrating the configuration of the switch unit, and Figures 7 to 8 are diagrams illustrating how the switch unit is assembled.
[0011] [composition] The switch unit in this invention is mounted on a vehicle and is used to detect operations on an operating device located on the vehicle. For example, the switch unit in this embodiment detects a depressing operation on a brake pedal mounted on a vehicle and illuminates a stop lamp in response to such depressing operation. However, the switch unit is not necessarily limited to being mounted on a vehicle, and may be mounted on any device and may detect operations on any operating device.
[0012] As shown in the exploded view of Figure 1, the switch unit comprises a switch device 10, an adjuster 20, and a fixing member 30, and is assembled as shown in Figure 2. Here, the fixing member 30 is installed near the brake pedal of the vehicle and is fixed to the vehicle itself. The fixing member 30 has a fixing member-side insertion hole 31, and the adjuster 20 is inserted into this fixing member-side insertion hole 31 and fixed, as will be described later. Furthermore, the switch device 10 is attached to the adjuster 20, thereby attaching the switch device 10 itself to the vehicle. At this time, one end of the shaft member 15 of the switch device 10 is pressed by the arm of the vehicle's brake pedal. The following describes each component in detail.
[0013] As shown in FIGS. 1 and 2, the switch device 10 has a case, and inside it, there are a shaft member 15, a moving body (not shown in the figure) pressed by the shaft member 15, and a detector that detects a switch operation according to the movement of the moving body. The switch device 10 is configured such that when one end side of the shaft member 15 is pressed by the arm of the brake pedal, the moving body moves downward in FIG. 1, and when the detector detects such movement, the operation of the brake pedal is detected. However, the switch device 10 may have any configuration. For example, it may not include a detector. As an example, the switch device 10 may be provided with a circuit that is directly opened and closed by the contact and non-contact of contacts according to the movement of the moving body, and the brake lamp may be directly lit and extinguished according to the opening and closing of such a circuit. In addition, in this embodiment, the detailed description of the internal configuration of the switch device 10 is omitted.
[0014] Here, referring to FIGS. 1 and 3, the configuration of the case of the switch device 10 will be described. FIG. 3 shows only the case of the switch device 10. The left figure is a perspective view, and the right figure is a plan view seen from above. The case of the switch device 10 is formed of a cylindrical body having a predetermined length, and has a first part 11 located at one end side, which is the side to be assembled to the adjuster 20, and a second part 12 located at the other end side, with the vicinity of the center in the longitudinal direction as the boundary. The first part 11 of the case is formed in a substantially cylindrical shape, and the shaft member 15 is accommodated in the hollow interior. Also, the external and internal shapes of the second part 12 of the case are formed larger than those of the first part 11, and it is formed in a substantially rectangular parallelepiped shape. And the hollow interior of the second part 12 communicates with the interior of the first part 11, and the moving body and the detector are accommodated.
[0015] As shown in FIG. 3, the first part 11 of the case of the switch device 10 is formed with a substantially circular outer shape, and screw parts 13 and 14 are formed to project further outward at two locations on the circumference. The two screw parts 13 and 14 are each formed in a linear convex shape having a predetermined width along the longitudinal direction, and a male screw part is formed on the surface that becomes the protruding end. The first part 11 of the switch device 10 will be rotated while being inserted into an insertion hole 22 formed in an adjuster 20 as described later. At that time, the male screw parts formed on the two screw parts 13 and 14 will be screwed with female screw parts formed on the inner wall of the insertion hole 22 of the adjuster 20.
[0016] In the present embodiment, as shown in the right diagram of FIG. 3, the screw parts 13 and 14 are each formed at two locations that are symmetric with respect to the center C of the first part 11 having a substantially circular outer shape as a symmetric point. However, the outer shapes of the two screw parts 13 and 14 at one end side, that is, when viewed from above, are formed asymmetrically with respect to the symmetric point C. Specifically, the width of the convex part of one of the screw parts 13, the first screw part 13, is formed wider than the width of the convex part of the other second screw part 14. That is, the first screw part 13 is formed in a shape that protrudes further outward and extends beyond the second screw part 14 located at a location symmetric with respect to the symmetric point C at the switch-side convex part 13a, which is the part indicated by the dotted line in the left diagram of FIG. 5. Also, a male screw part is formed on the surface that is the protruding end of the switch-side convex part 13a. Thus, the first screw part 13 is formed in a different shape from the second screw part 14 due to the extension of the switch-side convex part 13a, and the first part 11 is formed asymmetrically with respect to its center C as a symmetric point. The first part 11 is inserted into and rotated by the adjuster 20 as described later, and its center C is also the rotation center.
[0017] Next, the adjuster 20 (mounting member) will be described with reference to Figure 4. The left figure in Figure 4 is a perspective view, and the right figure is a plan view from above. The adjuster 20 is formed in a cylindrical shape with a predetermined length by fitting together two substantially semi-circular members. Specifically, the adjuster 20 has an insertion hole 22 formed in a substantially cylindrical main body 21, and the inner shape is formed so that the first part 11 of the case of the switch device 10 described above can be inserted. For this reason, the inner shape forming the insertion hole 22 of the adjuster 20 is formed in correspondence with the outer shape of the first part 11 of the case of the switch device 10, and is formed asymmetrically with the center C of the insertion hole 22 shown in the right figure of Figure 4 as the point of symmetry.
[0018] Specifically, the internal shape forming the insertion hole 22 of the adjuster 20 is as shown in the right-hand diagram of Figure 4. In this diagram, the pair of inner wall portions in the vertical direction are formed as approximately flat surfaces, while the pair of inner wall portions in the left-right direction, the inner circumferential portions 23 and 24, are formed as concave, approximately arcuate surfaces. On the wall surfaces of the inner circumferential portions 23 and 24, internal thread portions 23b and 24b are formed on the counterclockwise side, with the circumferential center as the boundary. In other words, on one inner circumferential portion 23, the upper portion 23a in Figure 4 is formed as an arcuate surface without irregularities, and the lower portion 23b in Figure 4 is formed as an internal thread portion. On the other inner circumferential portion 24, the lower portion 24a in Figure 4 is formed as an arcuate surface without irregularities, and the upper portion 24b in Figure 4 is formed as an internal thread portion. The male threaded portions formed on the threaded portions 13 and 14 of the first portion 11 of the switch device 10, which is inserted as described later, will be screwed into these female threaded portions 23b and 24b.
[0019] Furthermore, of the inner shape of the insertion hole 22 of the adjuster 20, one inner circumference 23 side is the part into which the first screw portion 13 of the first part 11 of the switch device 10 described above is inserted, so the one inner circumference 23 is formed wider than the other inner circumference 24. Specifically, the recessed part 23aa, indicated by the dotted line in the right diagram of Figure 5, in the smooth part 23a of the one inner circumference 23, is formed to be even more recessed than the other inner circumference 24, which is located at a point symmetrical with respect to the point of symmetry C. Thus, the one inner circumference 23 and the other inner circumference 24 are formed at two locations that are symmetrical with respect to the center C of the insertion hole 22, which has an inner shape that is approximately circular, but the one inner circumference 23 has a recessed part 23aa, so the inner shape viewed from one end is formed asymmetrically with respect to the point of symmetry C. Furthermore, the first part 11 of the switch device 10 is inserted into the insertion hole 22 and rotated, and its center C is also the center of rotation.
[0020] As described above, by making the internal shape of the insert hole 22 of the adjuster 20 asymmetric with respect to the center C of the insert hole 22, and further making the external shape of the first part 11 of the switch device 10 asymmetric with respect to the center C, the switch device 10 can be inserted into the insert hole 22 of the adjuster 20 at only one specific rotation angle.
[0021] Furthermore, the outer shape of the main body 21 of the adjuster 20 is formed in a substantially circular shape, and connecting parts that connect the two members constituting the adjuster 20 are formed projecting to the left and right on the sides in the left-right direction as shown in the right diagram of Figure 4. In addition, the outer shape of the main body 21 is formed with convex parts 25 and 26 that project upward in Figure 4, near both sides in the left-right direction as shown in the right diagram of Figure 4, that is, near the two connecting parts mentioned above. For this reason, the outer shape of the main body 21 of the adjuster 20 is formed asymmetrically with respect to the center C of the insertion hole 22. One of the convex parts 25 is formed in close proximity to the recess 23aa formed in the insertion hole 22, as shown in the right diagram of Figure 5. This ensures that the thickness of the main body 21 is maintained at a position where the convex part 25 and the recess 23aa are close to each other.
[0022] Next, the fixing member 30 will be described with reference to Figure 6. The fixing member 30 is formed from a plate-shaped member, and a part of it is shown in Figure 6. In other words, the fixing member 30 is actually fixed and equipped to a predetermined part of the vehicle, and its outer shape is not limited to being approximately square as shown in Figure 6. The fixing member 30 has a fixing member-side insertion hole 31 formed therein, and its inner shape is formed to be almost identical to the outer shape of the main body 21 of the adjuster 20 described above. That is, the inner shape of the fixing member-side insertion hole 31 of the fixing member 30 is approximately circular, with both sides recessed in the left-right direction, and further, fixing member-side recesses 32 and 33 that are recessed upward near both sides are formed. These fixing member-side recesses 32 and 33 are formed to correspond to the protrusions 25 and 26 formed on the main body 21 of the adjuster 20 described above. For this reason, the inner shape forming the fixing member-side insertion hole 31 of the fixing member 30 is formed asymmetrically with the center C of the fixing member-side insertion hole 31 as the point of symmetry. The adjuster 20 is inserted into the insertion hole 31 on the fixed member side, and the switch device 10 is then inserted into the adjuster 20 and rotated to assemble it, with the center of rotation being the same as the center C of the insertion hole 31 on the fixed member side.
[0023] As described above, by making the internal shape of the fixing member 30 that forms the fixing member side insertion hole 31 asymmetrical with respect to the center C, and further by making the external shape of the main body 21 of the adjuster 20 asymmetrical with respect to the center C, the adjuster 20 can be inserted into the fixing member side insertion hole 31 of the fixing member 30 at only one specific rotation angle.
[0024] [Assembly] Next, the operation for assembling the switch unit described above will be explained. First, as shown in Figure 1, the adjuster 20 is inserted into the fixing member side insertion hole 31 of the fixing member 30. At this time, as shown in Figure 7, the adjuster 20 is inserted into the fixing member side insertion hole 31 of the fixing member 30 by rotating it to a specific rotation angle. Specifically, the main body 21 of the adjuster 20 is inserted into the fixing member side insertion hole 31 of the fixing member 30 at a rotation angle such that the protrusions 25 and 26 formed on the main body 21 of the adjuster 20 correspond to the positions of the fixing member side recesses 32 and 33 formed in the fixing member side insertion hole 31. As a result, the adjuster 20 is assembled to the fixing member 30, as shown in Figure 7. The adjuster 20 and the fixing member 30 may be assembled in any structure, for example, by providing a claw portion that engages when the adjuster 20 is inserted into the fixing member side insertion hole 31 of the fixing member 30.
[0025] Next, as shown in Figure 1, the first portion 11 of the case of the switch device 10 is inserted into the insertion hole 22 of the adjuster 20, which is assembled to the fixing member 30. At this time, as shown in Figures 5 and the left diagram of Figure 8, the switch device 10 is rotated to a specific rotation angle before being inserted into the insertion hole 22 of the adjuster 20. Specifically, the first portion 11 of the switch device 10 is inserted into the insertion hole 22 of the adjuster 20 at a rotation angle such that the switch-side protrusion 13a formed on the first portion 11 of the case of the switch device 10 corresponds to the position of the recess 23aa formed in the insertion hole 22 of the adjuster 20. As a result, as shown in the left diagram of Figure 8, the first screw portion 13 of the first part 11 of the switch device 10 is positioned opposite the smooth portion 23a of one inner circumference 23 of the insertion hole 22 of the adjuster 20, and the second screw portion 14 of the first part 11 of the switch device 10 is positioned opposite the smooth portion 24a of the other inner circumference 24 of the insertion hole 22 of the adjuster 20. In Figure 8, the fixing member 30 to which the adjuster 20 is assembled is shown by a dotted line.
[0026] Subsequently, as shown in the right-hand diagram of Figure 8, the switch device 10 is rotated counterclockwise R while inserted into the adjuster 20. This causes the first threaded portion 13 of the first part 11 of the switch device 10 to engage with the female threaded portion 23b of one inner circumference 23 of the insertion hole 22 of the adjuster 20, and the second threaded portion 14 of the first part 11 of the switch device 10 to engage with the female threaded portion 24b of the other inner circumference 24 of the insertion hole 22 of the adjuster 20. This completes the assembly of the switch device 10 onto the adjuster 20, and as shown in Figure 2, a switch unit is formed by assembling the switch device 10, adjuster 20, and fixing member 30.
[0027] As described above, in this embodiment, the switch unit is assembled by inserting the adjuster 20 into the fixing member side insertion hole 31 of the fixing member 30 at a specific rotation angle, and the switch device 10 is assembled by inserting it into the insertion hole 22 of the adjuster 20 at a specific rotation angle. Therefore, the switch device 10 is mounted at a preset mounting angle, preventing it from being mounted at the wrong angle. As a result, a decrease in the detection accuracy of switch operations can be suppressed. Furthermore, as shown in Figure 5, even if the second part 12 of the switch device 10 is formed in a shape that is not symmetrical with respect to the center C of the first part 11, i.e., the rotation center C, it is possible to prevent it from being mounted at the wrong angle and resulting in an unintended arrangement. As a result, a decrease in the detection accuracy of switch operations and physical interference between parts can be suppressed.
[0028] Furthermore, by providing a protruding convex portion 25 and a recessed portion 23aa that forms the insertion hole 22 in close proximity to each other in the main body portion 21 of the adjuster 20, the thickness of the main body portion 21 can be ensured, and a decrease in strength can be suppressed.
[0029] In this embodiment, the switch device 10 is assembled by inserting it into the adjuster 20 and rotating it, but the configuration is not necessarily limited to assembly by rotation. For example, the switch device 10 may be provided with a claw portion that engages when inserted into the adjuster 20, and the assembly may be performed simply by insertion.
[0030] The above-described example of a switch device is one that illuminates the stop lamp when the brake pedal is pressed. However, the switch device in this invention is applicable to any type of switch operation. For example, it is applicable to switch devices that are operated by pressing the accelerator pedal or clutch pedal, or to any switch device that is operated by operating any part, not limited to pedals.
