A side stand bar provided on a motorcycle or the like is normally operated to be put in and taken out by the driver's foot. Moreover, they are placed in a severe operating environment where they are exposed to mud and water while they are running. Since the side stand switch provided near the side stand bar is also used in the same environment, sufficient durability, weather resistance and operational reliability are required. Furthermore, miniaturization of the side stand switch is also desired.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a side stand switch and a side stand device that are compact and have sufficient durability, weather resistance, and operational reliability.

One aspect of the present invention is a side stand switch that detects a rotational position of a side stand bar that is rotatably attached to a bracket, the switch body having an output that changes according to the rotational position of the side stand bar; and an engaging portion protruding from the switch body and capable of engaging with a protrusion provided on the bracket. This side stand switch is characterized in that the external connecting portion is formed integrally with the engaging portion.

According to such a configuration, since the engaging portion that can be engaged with the protrusion of the bracket and the external connection portion that can be electrically connected to the outside are integrally formed, the external connection portion is the engaging portion. The size can be reduced as compared with the case where it is formed separately.

In the above-described side stand switch, it is preferable that the engaging portion has a bifurcated shape into which the protrusion can be fitted, and the external connection portion is formed on the distal end side of the bifurcated branched portion of the engaging portion. In this case, it is preferable that the external connection portion is formed on the tip side of both bifurcated bifurcated portions of the engaging portion. Accordingly, by connecting the connector to the external connection portion, the switch body can be firmly and well-balanced fixed by sandwiching the protrusion between the two bifurcated branch portions.

In the above-described side stand switch, it is preferable that the engaging portion has a bifurcated shape into which the projection can be fitted, and that the fitting depth of the projection in the bifurcated shape is 1/2 or more of the diameter of the projection. As a result, half or more of the diameter of the protruding portion is fitted into the bifurcated shape of the engaging portion of the switch body, and the engaging portion can sufficiently receive the force in restricting the rotation.

The side stand switch further comprises a connector connected to the switch body, the connector having a connection part connected to the external connection part, and the connection part being externally connected to the projection from the opposite side of the switch body. connected with the department. As a result, by connecting the connector to the switch body, the connector can be connected to the switch body in such a manner that the protrusion of the bracket is sandwiched between the clamping regions provided between the connector and the engaging portion of the switch body. . Further, since the connector can be arranged on the extension line connecting the support shaft of the side stand bar and the projection, the size of the side stand switch including the connector can be reduced.

In the side stand switch described above, it is preferable that the connecting portion of the connector is connected to the engaging portion at the tip of the bifurcated branch portion of the engaging portion. Thereby, the symmetry of the connection structure between the switch body and the connector is enhanced, and stable and reliable connection can be achieved.

One aspect of the present invention includes a side stand bar that supports a vehicle body in an upright state, a bracket attached to the vehicle body, a pivot bolt that rotatably attaches the side stand bar to the bracket, the side stand switch, and the side stand switch attached to the pivot bolt. and a fixing bolt attached by tightening. With such a configuration, a highly reliable and compact side stand switch can be arranged around the support shaft of the side stand bar so that the connector can be arranged on the extension line that connects the support shaft of the side stand bar and the protrusion provided on the bracket. can be placed in

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, a case where the present invention is applied to a side stand device for a motorcycle will be described. However, the application target of the side stand switch according to the present embodiment is not limited to this, and can be changed as appropriate. Further, in the following description, the same members are denoted by the same reference numerals, and the description of the members that have already been described will be omitted as appropriate.

(side stand device)
FIG. 1 is an exploded perspective view illustrating the configuration of the side stand device according to this embodiment.
FIG. 2 is a perspective view illustrating the configuration of the side stand device according to this embodiment.
A side stand device 1 according to the present embodiment supports a motorcycle in an upright state when it is parked. It is configured with a side stand bar 3 attached. Further, the side stand device 1 is provided with a side stand switch 5 via a fixing bolt 6 on the pivot bolt 4 , and the side stand switch 5 detects the rotational position of the side stand bar 3 .

The bracket 2 includes a plate-like portion 11 and a post 12 which is a protrusion provided upright from the plate-like portion 11 . A shaft hole 13 is formed through the plate-like portion 11 in the thickness direction at the mounting position of the side stand bar 3 . The post 12 functions as a positioning pin for positioning the side stand switch 5, and also has a function of restricting rotation of a case member 31, which will be described later, along with the rotation of the side stand bar 3. As shown in FIG. Also, the post 12 may be used as a locking pin that is locked to a return spring (not shown).

The side stand bar 3 is attached to the bracket 2 by a pivot bolt 4, and is rotatable about the pivot bolt 4 between an upright position grounded on the ground and a retracted position substantially horizontal with respect to the ground. It is A pair of bifurcated connecting portions 15 and 16 are provided on the base end side of the side stand bar 3 so as to sandwich the plate-like portion 11 therebetween. 17 and 18 are formed. An engagement hole 19 that engages with the rotor member 32 of the side stand switch 5 is formed through the vicinity of the shaft hole 17 of one connecting portion 15 .

The pivot bolt 4 is inserted through the shaft holes 17 and 18 of the pair of connecting portions 15 and 16 and the shaft hole 13 of the bracket 2 with the bracket 2 sandwiched between the pair of connecting portions 15 and 16 . The pivot bolt 4 is fixed to the pair of connecting portions 15 and 16 by being tightened with a fixing nut (not shown). As a result, the side stand bar 3 is rotated with respect to the bracket 2 integrally with the pivot bolt 4 . A screw hole 22 into which the fixing bolt 6 is screwed is formed in the head 21 of the pivot bolt 4 .

The side stand switch 5 detects whether the side stand bar 3 is positioned on the upright position side or the retracted position side, and is attached to the head portion 21 of the pivot bolt 4 by the fixing bolt 6 . A detailed configuration of the side stand switch 5 will be described later.

The fixing bolt 6 is inserted through the side stand switch 5 and tightened while being screwed into the screw hole 22 of the pivot bolt 4 , thereby fixing the side stand switch 5 to the pivot bolt 4 . The fixing bolt 6 has a circular flange portion 27 on its head, and the side stand switch 5 is stably pressed by this flange portion 27 .

(side stand switch)
Next, the detailed configuration of the side stand switch 5 will be described.
The side stand switch 5 for detecting the rotation of the side stand bar 3 includes a switch body 51 , an external connection portion 505 and an engaging portion 510 . Also, the side stand switch 5 may have a connector 52 . The switch body 51 is fixedly attached to the bracket 2 and opens and closes according to the rotational position of the side stand bar 3 .

The switch body 51 has a case member 31 , a rotor member 32 provided inside the case member 31 , and a stator member 33 provided inside the case member 31 . The case member 31 is made of synthetic resin or the like, and is positionally fixed with respect to the post 12 provided on the plate-like portion 11 of the bracket 2 . The rotor member 32 is rotatably housed inside the case member 31 . The rotor member 32 is engaged with the side stand bar 3 by means of an engaging pin (not shown) inserted through the engaging hole 19 so as to rotate together with the side stand bar 3 .

The stator member 33 is fixed inside the case member 31 with respect to the rotor member 32 that is rotatably housed in the case member 31 . As a result, the relative rotation angle between the rotor member 32 and the stator member 33 that rotate together with the side stand bar 3 changes.

The stator member 33 is provided with a fixed contact (not shown), and the rotor member 32 is provided with a movable contact (not shown). Therefore, when the relative rotation angle between the rotor member 32 and the stator member 33 changes due to the rotation of the side stand bar 3, the contact state between the fixed contact of the stator member 33 and the movable contact of the rotor member 32 changes. The state of contact or non-contact between the fixed contact and the movable contact corresponds to either the upright position or retracted position of the side stand bar 3 . As a result, the signal output from the switch body 51 is used to detect whether the side stand bar 3 is in the upright position or in the retracted position.

The detection method of the switch body 51 may be a magnetic method using a magnet and a magnetic detection device (such as a GMR sensor) instead of a contact method using a fixed contact and a movable contact. The relative position between the magnet and the magnetism detecting device is changed as the rotor member rotates, that is, the change in magnetism detected by the magnetism detecting device is measured to determine whether the side stand bar 3 is in the upright position or retracted position. may be detected.

In the side stand switch 5 , the rotor member 32 and the stator member 33 are provided coaxially with the pivot bolt 4 that is the support shaft of the side stand bar 3 . As a result, the side stand switches 5 can be concentrated around the support shaft of the side stand bar 3, and the size of the switch mechanism can be reduced.

The external connection portion 505 is a portion for electrical connection with the outside, and has a connection terminal 51a. The engaging portion 510 is provided to extend outward from the peripheral portion of the case member 31 . The engaging portion 510 engages with the post 12 provided on the plate-like portion 11 of the bracket 2 . Specifically, the engaging portion 510 has a bifurcated shape, and the post 12 is fitted between two branched portions 511 of this bifurcated shape. As a result, the case member 31 is positionally fixed with respect to the post 12 . The engaging portion 510 may be provided integrally with the case member 31 or may be provided separately.

In the side stand switch 5 of this embodiment, the external connection portion 505 is provided integrally with the engaging portion 510 . That is, the external connection portion 505 is formed integrally with the engaging portion 510 on the distal end side of the engaging portion 510 . A connector 52 is connected to the external connection portion 505 . The connector 52 has a connection portion 520 that is connected to the external connection portion 505 from the opposite side of the switch body 51 with respect to the post 12 . Accordingly, by connecting the connector 52 to the switch body 51 , a sandwiching region S for sandwiching the post 12 is provided between the connector 52 and the engaging portion 510 of the switch body 51 .

A connection terminal 51 a is provided at the tip of each bifurcated branched portion 511 of the engaging portion 510 . On the other hand, the connection portion 520 of the connector 52 is provided with a connection terminal 52a that fits with the connection terminal 51a. The connection terminal 51a has a signal line extending from the switch main body 51, and is fitted and connected to the connection terminal 52a of the connector 52 to achieve mechanical connection and electrical continuity.

Further, for example, the connection terminal 51a is provided in a cylindrical shape having a hole in the center, and the connection terminal 52a is provided in a cylindrical shape having a concave groove on the outside. As a result, when the connector 52 is connected to the switch body 51, the cylindrical connection terminal 52a is fitted into the central hole of the connection terminal 51a, and the edge of the connection terminal 51a is fitted into the groove on the outside of the connection terminal 52a. fixed together. Therefore, the creepage distance is longer than in a simple concavo-convex connection structure, and the waterproofness and dustproofness of the connection portion can be improved.

In the present embodiment, as shown in FIG. 1, the outer shape of the connection terminal 51a is such that the bracket 2 side (the lower side) is a rectangular parallelepiped column, the upper side is a cylinder, and the grooves on the outer side of the connection terminal 52a are formed. is made to follow the outer shape of the connection terminal 51a. With such a shape, it is possible to prevent the connector 52 from being reversely inserted. In particular, when the detection method of the side stand switch 5 is magnetic, the reverse insertion prevention structure is effective because of the polarity.

The connecting portion 520 of the connector 52 is preferably connected at each of the distal ends of both bifurcated branch portions 511 of the engaging portion 510 . As a result, when the connector 52 is connected to the switch body 51 , the connector 52 is connected so as to close the bifurcated opening of the engaging portion 510 , and the post 12 is connected to both bifurcated branch portions 511 of the engaging portion 510 . The connector 52 can be firmly and well-balanced fixed to the switch main body 51 by being sandwiched between them.

Moreover, the fitting depth of the post 12 in the bifurcated shape of the engaging portion 510 is preferably 1/2 or more of the diameter of the post 12 . FIG. 3 is a schematic diagram for explaining the fitting depth of the engaging portion. As shown in FIG. 3, when the line connecting the center c1 of the fixing bolt 6 and the center c2 of the post 12 is defined as a line L, the fitting depth D1 of the fork shape of the engaging portion 510 is the direction along the line L. is the length from the end 510a of the engaging portion 510 on the connector 52 side to the bottom 510b of the bifurcated concave portion. Also, the diameter of the post 12 in the direction along the line L (the diameter when the post 12 is cylindrical) is a diameter D2. In this case, the depth D1 preferably satisfies D1≧1/2D2.

As a result, when fitting the engaging portion 510 to the post 12 , half or more of the diameter D<b>2 of the post 12 is fitted into the forked shape of the engaging portion 510 . Therefore, the engaging portion 510 can sufficiently receive the force when restricting the rotation of the switch body 51 . That is, if the post 12 is shallowly fitted into the engaging portion 510 , a large force for suppressing the rotation of the switch body 51 is applied to the connector 52 side, but the post 12 is deeply fitted into the engaging portion 510 . Therefore, the side stand switch 5 can be fixed without applying a large load to the connector 52 side.

Further, it is preferable to provide a relief portion 521 so that the connector 52 does not come into contact with the post 12 when the connector 52 is connected to the switch body 51 with the post 12 fitted in the engaging portion 510 . As a result, the force for suppressing the rotation of the switch body 51 is not applied to the connector 52, and the load on the connector 52 can be suppressed.

In order to facilitate the provision of the relief portion 521 as described above, the connection portion 520 of the connector 52 preferably has a bifurcated shape like the engaging portion 510, but does not necessarily have to have a bifurcated shape. Also, the sandwiching area S formed by connecting the connector 52 to the switch body 51 is approximately equal in size to the post 12, or is large enough to fit the post 12 into the engaging portion 510 or to connect the connector 52. It is preferable to have a size that allows for a margin of As a result, the post 12 can be held in the holding region S with less rattling. The width of the clamping region S (the width W in the direction orthogonal to the line L) is set substantially equal to the diameter of the post 12 (diameter D2). As a result, the rotation of the side stand switch 5 can be reliably restricted.

In the side stand switch 5 having such a configuration, by connecting the connector 52 to the switch body 51, the post 12 is sandwiched between the clamping regions S provided between the connector 52 and the engaging portion 510 of the switch body 51. can be installed as follows. Therefore, the engaging portion 510 for regulating the rotation of the switch body 51 is also used as a connecting portion of the connector 52, and the connector 52 is provided on an extension of the line L connecting the support shaft of the side stand bar 3 and the post 12. can be arranged, the size of the side stand switch 5 including the connector 52 can be reduced.

In addition, the side stand switch 5 is fixed so as to surround the post 12 (around the post 12 as a center), and the symmetry of the connection structure between the switch body 51 and the connector 52 (line symmetry about the line L) is achieved. This allows for a stable and reliable connection.

(Operation of side stand device)
Next, the operation of the side stand device 1 will be described.
FIG. 4 is a schematic diagram illustrating the operation of the side stand device 1. FIG.
The side stand bar 3 of the side stand device 1 is configured to be rotatable between a standing position in contact with the ground G and a retracted position substantially horizontal with respect to the ground G. As shown in FIG. The side stand switch 5 is restricted from rotating by a post 12 provided on the bracket 2 and fixed to the bracket 2 regardless of the rotation of the side stand bar 3 .

In such a side stand device 1, when the motorcycle is to be erected, the driver puts the side stand bar 3 with his/her foot up to the standing position. As a result, a signal indicating the upright position is output from the switch body 51 of the side stand switch 5 and sent from the connector 52 to the vehicle body side.

On the other hand, when the motorcycle is run, the driver flips up the side stand bar 3 with his foot. As a result, the side stand bar 3 rotates from the upright position to the retracted position. By this rotation, a signal indicating the retracted position is output from the switch body 51 of the side stand switch 5 and sent from the connector 52 to the vehicle body side.

(Comparative example)
FIGS. 5(a) and 5(b) are plan views comparing side stand devices.
FIG. 5(a) shows a side stand device 1 and a side stand switch 5 according to this embodiment, and FIG. 5(b) shows a side stand device 1B and a side stand switch 5B according to a comparative example.

As shown in FIG. 5(a), the side stand switch 5 of the side stand device 1 according to this embodiment includes an engaging portion 510 that can be engaged with the post 12 of the bracket, and an external connection portion 505 that is connected to the connector 52. are integrally formed. When the connector 52 is connected to the external connection portion 505 , the post 12 is sandwiched between the sandwiching region S provided between the engaging portion 510 and the connector 52 . Therefore, the engaging portion 510 that is fitted into the post 12 and used to restrict the rotation of the switch body 51 is also used as the connection portion with the connector 52 . Moreover, the switch body 51 and the connector 52 are attached so as to surround the post 12, and the connection structure between the switch body 51 and the connector 52 is left-right symmetrical.

On the other hand, as shown in FIG. 5(b), in the side stand device 1B according to the comparative example, the engaging portion 510B fitted to the post 12 and the connection portion 525 with the connector 52B are separate bodies, and furthermore, the switch body The connection configuration between 51B and connector 52B is left-right asymmetrical.

As in the side stand switch 5 according to the present embodiment, the engaging portion 510 and the external connecting portion 505 are integrally formed, so that when the engaging portion 510B and the connecting portion 525 are separately formed, It is possible to achieve miniaturization by comparison. In addition, like the side stand switch 5 according to the present embodiment, the switch body 51 and the connector 52 are highly symmetrically arranged around the post 12, so that the area around the switch of the side stand device 1 can be miniaturized. In addition, when connecting the connector 52, it is possible to achieve a well-balanced and reliable connection.

Moreover, in the side stand switch 5 according to the present embodiment, the height of the connector 52 can be reduced as compared with the side stand switch 5B according to the comparative example. That is, in the present embodiment, since the connector 52 is attached to the bifurcated shape of the engaging portion 510 divided into left and right, the connection terminals can be arranged on the left and right according to each of the bifurcated shapes.

On the other hand, in the comparative example, since the connection portion 525 for connecting the connector 52B is provided beside the engaging portion 510B, it is necessary to arrange the connection terminals in the thickness direction so as not to increase the width of the whole. . As a result, it is difficult to reduce the height of the connector 52B in the comparative example.

If the connector 52 can be reduced in height, it can be attached near the base of the post 12 when locking the return spring to the post 12 . Since a large force is applied to the post 12 to which the return spring is locked, the load on the post 12 can be reduced by attaching the post 12 as close to the base as possible. In the present embodiment, the engagement position of the return spring to the post 12 can be made closer to the root side than in the comparative example, and the load applied from the return spring to the post 12 can be reduced. Also, if the motorcycle were to overturn on the side where the side stand switch 5 was attached, the engaging portion 510 and the connector 52 would be less likely to be damaged by hitting the road surface.

In addition, since the side stand switch 5 can be made smaller in this embodiment, the degree of design freedom increases when the side stand device 1 is laid out on the vehicle body frame. Moreover, even if the side stand switch 5 is positioned near the feet of the driver of the motorcycle or the like, it does not interfere with driving.

As described above, according to the present embodiment, it is possible to provide the side stand switch 5 and the side stand device 1 that are miniaturized and have sufficient durability, weather resistance, and operational reliability.

Although the present embodiment has been described above, the present invention is not limited to these examples. For example, the bracket 2 may be part of the body frame instead of being separate from the body frame. Also, the post 12, which is a projection provided on the bracket 2, may have a projection shape other than a cylindrical shape. In this case, it is preferable that the sandwiching region S is matched with the projection shape. In addition, the side stand device 1 can be applied not only to motorcycles but also to objects other than motorcycles as long as they are objects to be supported in an upright state. In addition, additions, deletions, and design changes made by those skilled in the art to the above-described embodiments, and combinations of features of the configuration examples of the embodiments, are also included in the gist of the present invention. is included in the scope of the present invention as long as it has
