Description

[Technical Field]

[0001] The present technology relates to a switch system and a vehicle. [Background technology]

[0002] BACKGROUND ART Various types of switch devices and switch systems have been known in the past to be mounted on vehicles, etc. Patent Document 1 discloses a dimmer switch that is electrically connected by contact of metal terminals when an operating portion is operated.

[0003] Furthermore, in recent years, as it has become common to detect switch operations using small current values, switch devices that can easily be provided with a waterproof structure have been widely adopted.

[0004] For example, Patent Document 2 uses rubber contacts that are electrically connected when the operating part is pressed and the movable contact and fixed contact come into contact with each other. While the contacts are electrically connected, the motor for the power window, which is an electrical component, operates. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5824234 [Patent Document 2] Japanese Utility Model Application Publication No. 2-77829 Summary of the Invention [Problem to be solved by the invention]

[0006] In the case of a switch device such as that described in Patent Document 2, when the device is released, the contacts separate to become non-conductive and then return to their initial position by their own elasticity. On the other hand, if it is desired to continue the operation of an electrical component, it is usually necessary to keep the contacts in a conductive state.

[0007] However, switch devices that are designed to return to their initial position independently may undergo plastic deformation if they are held down for a long period of time, making it difficult for them to return to their original position quickly even after being released. This can lead to improper switch operation, especially in situations where electrical equipment is left in operation for a long period of time.

[0008] The present technology aims to maintain proper operation of the switch for a long time. [Means for solving the problem]

[0009] In order to achieve the above object, the switch system of the present technology includes a switch that becomes conductive when pressed, becomes non-conductive when released, and returns to its initial position by itself; an operating unit that is operated to reciprocate; a drive unit that is formed integrally with the operating unit or moves reciprocally in conjunction with the operating unit, and that moves sequentially to a first position where the switch is not pressed, a second position where the switch is pressed, and a third position where the switch is not pressed during the forward stroke of the operation of the operating unit; and a control unit that controls the operation of electrical equipment based on the state of the switch, wherein, when the electrical equipment is not being operated, the control unit starts the operation of the electrical equipment in response to a change of the switch from a non-conductive state to a conductive state, and continues the operation of the electrical equipment even if the switch changes from a conductive state to a non-conductive state, and when the electrical equipment is being operated, the control unit stops the operation of the electrical equipment in response to a change of the switch from a non-conductive state to a conductive state, or when the switch changes from a non-conductive state to a conductive state and then back to a non-conductive state. [Effects of the Invention]

[0010] According to this technique, proper operation of the switch can be maintained for a long time. [Brief explanation of the drawings]

[0012] Hereinafter, embodiments of the present technology will be described with reference to the drawings.

[0013] (First embodiment) 1 is a block diagram of a vehicle to which a switch system according to a first embodiment of the present technology is applied. The switch system 100 includes a switch device 102 and a control unit 101. The control unit 101 includes a CPU, a ROM, a RAM, etc., which are not shown. The switch system 100 is mounted on a vehicle 104, for example. The vehicle 104 is a saddle-ride vehicle, and the switch device 102 is, for example, a handlebar switch attached to a handlebar. The vehicle 104 includes a headlight 103, which is an example of an electrical component controlled in accordance with the state of the switch system 100.

[0014] The application of the switch system 100 is not limited to the vehicle 104, and the switch system 100 may be configured independently. Furthermore, the control unit 101 is assumed to be a control unit that controls electrical equipment of the vehicle 104, but when the switch system 100 is configured independently, the control unit 101 may be a control unit that is provided in the switch system 100 separately from the control unit of the vehicle 104.

[0015] Fig. 2 is a perspective view of the switch device 102. Fig. 3 is a perspective view of the switch device 102, showing a cross section that passes through the center of the switch SW and is perpendicular to the shaft portion 14 (described later).

[0016] The switch device 102 is broadly composed of a base member 40, a rubber member 30, a case 20 (holding member), an operation knob 10 (operating portion), and a link member 19 (moving member). The rubber member 30, which is an elastic member, is placed on the base member 40, and the case 20 is placed on the rubber member 30. There is no restriction on the method for fixing the base member 40, rubber member 30, and case 20.

[0017] The switch SW and other switches 39 are arranged on the base member 40 and across the case 20. A circuit board is arranged on the base member 40, and fixed contacts 34 are arranged on the circuit board surface. The main part of the switch SW is made up of a rubber member 30. The switch SW is made up of a push rod 33 and a rubber contact 32.

[0018] The rubber contact 32 is a switch that is brought into a conductive state when the contacts come into contact with each other. The rubber contact 32 has a movable part that bulges upward from the base of the rubber member 30, and the movable part moves up and down. A push rod 33 is disposed at the upper end of the movable part, and a movable contact 35 is disposed at the lower end of the movable part, facing a fixed contact 34. The push rod 33 is held by the case 20 so as to be movable in the pushing direction (up and down).

[0019] When the push rod 33 is pressed, it is displaced downward, and the movable part of the rubber contact 32 is also displaced accordingly, and the movable contact 35 comes into contact with the fixed contact 34, thereby establishing a conductive state (ON). When pressed, the switch SW is constantly biased upward by the elastic restoring force of the movable part. When the movable contact 35 separates from the fixed contact 34, it is established a non-conductive state (OFF). Therefore, when the switch SW is pressed, it is established a conductive state, and when released, it is established a non-conductive state and returns to its initial position by itself.

[0020] A detection signal indicating conduction (ON) / non-conduction (OFF) is sent to the control unit 101. The control unit 101 controls the operation of the headlight 103, which is an electrical component, based on the state (ON / OFF) of the switch SW. The other switches 39 are configured in the same way as the switch SW.

[0021] The operation knob 10 is rotatably held relative to the case 20. The case 20 has a pair of walls 21, 22 (FIG. 2), and a pivot hole 26 is formed in each of the walls 21, 22. A pair of shafts 14 protruding from the operation knob 10 are pivotally supported in the corresponding pivot holes 26 (only the shafts 14 and pivot holes 26 corresponding to the wall 22 are shown in FIG. 2). Therefore, the operation knob 10 is operated back and forth, and rotates about the pivot holes 26 when operated.

[0022] The operation knob 10 has a contact portion 11, a pressing portion 15, and a click portion 12. A link member 19 is connected to the operation knob 10 via a link shaft 18 (FIG. 3). The link member 19 is rotatable (movable) relative to the operation knob 10 around the link shaft 18. The lower end of the link member 19 is a drive portion 19a for pressing and driving the push rod 33 of the switch SW. In addition, a guided shaft 13 protrudes from the link member 19 toward the wall portions 21 and 22.

[0023] Cam grooves 24 for guiding the link member 19 are formed in the walls 21 and 22 of the case 20. The guided shaft 13 is engaged with the corresponding cam groove 24 of the link member 19. During the rotational process of the operation knob 10, the guided shaft 13 moves along the cam groove 24. Therefore, the position and posture of the link member 19 are determined by the positions of the link shaft 18 and the guided shaft 13, and the position of the drive unit 19a is also determined.

[0024] The case 20 also has a guide portion 25 formed in a portion facing the click portion 12 (FIG. 3). When the operation knob 10 is rotated, the click portion 12 slides on the guide portion 25, producing a predetermined operating feel.

[0025] The guide portion 25 has a valley portion, and the position of the operation knob 10 when the click portion 12 is engaged with the valley portion is the neutral position. Focusing on the drive of the switch SW, the +R direction from the neutral position is the forward direction for the rotation of the operation knob 10, and the return direction is the -R direction for the rotation. Note that the other switch 39 is driven by the pressing portion 15. Focusing on the drive of the other switch 39, the reciprocating direction from the neutral position is opposite to that for the switch SW. Hereinafter, since the focus will be on the drive of the switch SW, when the forward direction and return direction are simply used, they will mean the +R direction and the -R direction.

[0026] The case 20 is also provided with a stopper portion 23. During the forward stroke of the operation of the operation knob 10, the abutment portion 11 of the operation knob 10 abuts against the stopper portion 23, thereby restricting the rotation end position of the operation knob 10.

[0027] 4(a) and 4(b) are transition diagrams of the forward operation stroke of the operating knob 10 for driving the switch SW.

[0028] As described above, when the link member 19 moves back and forth in conjunction with the operation knob 10, it is guided by the cam groove 24 and changes its position. In Figures 2 and 3, the operation knob 10 is in the neutral position, and the driver 19a is not pressing down the switch SW. In Figure 4(a), the driver 19a is pressing down the switch SW, and in Figure 4(b), the driver 19a is not pressing down the switch SW.

[0029] The first, second, and third positions to which the driver 19a moves in sequence during the forward operation stroke of the operation knob 10 are defined as follows: The position of the driver 19a corresponding to the rotation range from when the operation knob 10 is in the neutral position to when the switch SW is turned ON is called the "first position." The position of the driver 19a corresponding to the rotation range in which the switch SW is turned ON is called the "second position." The position of the driver 19a corresponding to the rotation range in which the switch SW is turned OFF after moving further from the second position is called the "third position." The positions of the driver 19a in Figures 3, 4(a), and 4(b) correspond to the first, second, and third positions, respectively.

[0030] Such a change in position is achieved by the engagement of the guided shaft 13 of the link member 19 with the curved cam groove 24. When the drive unit 19a moves from the first position to the second position, the link shaft 18 rotates integrally with the operation knob 10 in the +R direction, while the guided shaft 13 moves roughly diagonally downward along the cam groove 24, causing the link member 19 to rotate slightly in the +R direction. Then, the drive unit 19a presses down the push rod 33, turning the switch SW ON.

[0031] When the drive unit 19a moves from the second position to the third position, the guided shaft 13 moves generally diagonally upward along the cam groove 24, causing the link member 19 to rotate significantly in the +R direction. As a result, the drive unit 19a moves away from the push rod 33, and the switch SW turns OFF. In this way, the state of the switch SW changes from OFF to ON to OFF during both the forward stroke and the backward stroke.

[0032] The operating load also changes as the click portion 12 slides along the guide portion 25. The click portion 12 is fixed to the main body of the operating knob 10 via an elastic member, and is movable in the protruding direction.

[0033] FIG. 5 is a diagram showing the relationship between the rotation angle and the operation load in the operation stroke of the operation knob 10.

[0034] In FIG. 5, areas P1, P2, and P3 correspond to the first, second, and third positions, respectively. As the operation knob 10 rotates in the forward direction from the neutral position (initial rotation position), a force is generated to rotate the operation knob 10 toward the neutral position due to the contact angle between the click portion 12 and the guide portion 25, resulting in an increase in the operation load. When the operation knob 10 passes the second position, the operation load is reversed, and a force is generated to rotate the operation knob 10 from the second position to the third position. In this state, the abutting portion 11 abuts against the stopper portion 23, causing the operation knob 10 to stay at the rotation end position. Therefore, the operation knob 10 does not stay in the second position but rotates toward the neutral position or the rotation end position.

[0035] 6 is a flowchart of the electrical component control process, which is implemented by the control unit 101 executing a program stored in the ROM or the like.

[0036] In this embodiment, an example is shown in which the headlights 103 are changed between a low beam state and a high beam state. ON / OFF in FIG. 6 indicates whether the movable contact 35 and the fixed contact 34 of the switch device 102 are in a conductive / non-conductive state. Not operating the headlights 103 means that the headlights 103 are in a low beam state, and operating the headlights 103 means that the headlights 103 are in a high beam state. In this process, when the operation knob 10 is in the neutral position, the headlights 103 are in a low beam state. Incidentally, although separate from this process, pressing another switch 39 also activates the flashing lights.

[0037] Immediately after the start of this process, the operation knob 10 is in the neutral position, and the headlights 103 are not in operation. In step S101, the control unit 101 determines whether (the state of) the switch SW has changed from OFF (non-conductive state) to ON (conductive state). The control unit 101 continues this determination until the switch SW changes from OFF to ON, and if the switch SW has changed from OFF to ON, the control unit 101 proceeds to step S102 and starts the operation of the headlights 103. Therefore, if the headlights 103 are not in operation, the operation of the headlights 103 starts when the drive unit 19a moves from the first position to the second position.

[0038] Next, in step S103, the control unit 101 determines whether the switch SW has changed from ON to OFF. The control unit 101 continues this determination until the switch SW has changed from ON to OFF, and if the switch SW has changed from ON to OFF, the control unit 101 proceeds to step S104 and continues operating the headlight 103. Therefore, even though the drive unit 19a has moved from the second position to the third position during the forward stroke of the operation of the operation knob 10 and the switch SW has turned OFF, the operation of the headlight 103 continues.

[0039] Next, in step S105, the control unit 101 determines whether the switch SW has changed from OFF to ON. The control unit 101 continues this determination until the switch SW has changed from OFF to ON, and if the switch SW has changed from OFF to ON, the process proceeds to step S106. The change of the switch SW from OFF to ON means that the drive unit 19a has moved from the third position to the second position during the return stroke. In step S106, the control unit 101 stops the operation of the headlight 103.

[0040] Therefore, when the operation knob 10 is operated in a backward direction while the headlight 103 is in operation, if the drive unit 19a reaches the second position from the third position, the operation of the headlight 103 is stopped. Note that, during the backward movement of the operation knob 10, the drive unit 19a moves from the third position to the first position via the second position. Therefore, after step S106, the control unit 101 returns to step S101.

[0041] According to this embodiment, when the headlights 103 are not in operation, the control unit 101 starts operation of the headlights 103 in response to the switch SW changing from OFF to ON, and continues operation of the headlights 103 even when the switch SW changes from ON to OFF. Also, when the headlights 103 are in operation, the control unit 101 stops operation of the headlights 103 in response to the switch SW changing from OFF to ON.

[0042] Therefore, even if the headlights 103 remain on in the high beam mode and the operation knob 10 is kept at the rotation end position for a long time, the movable portion of the rubber member 30 does not continue to deform, so the self-recovery force of the switch SW is maintained for a long time, and the appropriate operation of the switch SW can be maintained for a long time.

[0043] Furthermore, since the link member 19 changes its posture while being guided by the cam groove 24, the switch SW can clearly change from OFF to ON to OFF within the limited rotation range of the operating knob 10, thereby maintaining high detection accuracy.

[0044] In step S105, the process proceeds to step S106 in response to the switch SW changing from OFF to ON. However, the process may proceed to step S106 in response to the switch SW changing from OFF to ON and then back to OFF. In this case, the operation of the headlight 103 is stopped in response to the drive unit 19a moving from the third position to the first position via the second position.

[0045] In this embodiment, the operation of the headlights 103 is started when the switch SW changes from OFF to ON (S101 → S102). However, the condition for starting the operation of the headlights 103 is not limited to this. For example, if the headlights 103 are not in operation, the operation of the headlights 103 may be started when the switch SW changes from OFF to ON and then changes from ON to OFF. In this case, in the flowchart of FIG. 6, the control unit 101 may perform no control in step S102 and control the headlights 103 to start operating in step S104. That is, if the headlights 103 are not in operation, the control unit 101 starts the operation of the headlights 103 in response to the switch SW changing from OFF to ON and then changing back to OFF.

[0046] (Second embodiment) 7(a) to 7(c) are transition diagrams of the forward operation stroke of the operating knob 10 of the switch device according to the second embodiment of the present technology.

[0047] In this embodiment, the configurations of the operation knob 10 and the link member 19 are different from those of the first embodiment, but the other configurations are the same. In the first embodiment, the link member 19 moves with a rotational movement, but in this embodiment, it moves horizontally in a straight line.

[0048] The link member 19 is held by the case 20 so as to be linearly movable in the left-right direction in Figure 7. An engagement pin 53 is provided on the link member 19. Meanwhile, an engagement groove 52 is formed in a part of the operation knob 10. The engagement pin 53 is engaged with the engagement groove 52.

[0049] 7(a), (b), and (c) correspond to the first, second, and third positions, respectively. When the operation knob 10 is rotated, the engagement pin 53 is driven by the engagement groove 52, and the link member 19 moves left and right, for example, to the left during the forward stroke of the operation.

[0050] Even with this configuration, the drive unit 19a moves back and forth in conjunction with the operation knob 10, and during the forward stroke of the operation, it moves sequentially from the first position to the second position to the third position, and presses the switch SW midway through the movement stroke.

[0051] According to this embodiment, it is possible to achieve the same effect as the first embodiment in terms of maintaining the proper operation of the switch SW for a long period of time.

[0052] The link structure between the operation knob 10 and the link member 19 is not limited to those exemplified in the first and second embodiments. Furthermore, the movement of the link member 19 is not limited to rotational movement or linear movement.

[0053] (Third embodiment) In the first and second embodiments, the link member 19 having the drive unit 19a is configured separately from the operation knob 10 and moves back and forth in conjunction with the operation knob 10. However, the present invention is not limited to this, and the drive unit 19a may be configured integrally with the operation knob 10.

[0054] 8(a) to 8(c) are transition diagrams of the forward operation stroke of the operating knob 10 of the switch device according to the third embodiment of the present technology.

[0055] The drive unit 19a is integrally formed as part of the operation knob 10. The positions of the drive unit 19a in Figures 8(a), (b), and (c) correspond to the first position, the second position, and the third position, respectively. The drive unit 19a rotates in conjunction with the rotation of the operation knob 10, and presses the switch SW midway through the rotation process.

[0056] Even with this configuration, the drive portion 19a moves back and forth in conjunction with the operation knob 10, and moves sequentially from the first position to the second position and the third position during the forward stroke of the operation.

[0057] According to this embodiment, it is possible to achieve the same effect as the first embodiment in terms of maintaining the proper operation of the switch SW for a long period of time.

[0058] (Fourth embodiment) In the first to third embodiments, a single switch SW is provided, but in a fourth embodiment of the present technology, two switches SW are provided.

[0059] 9(a) and 9(b) are schematic diagrams of a first example and a second example of a switch device according to a fourth embodiment of the present technology, respectively. In this embodiment, a first switch SWA and a second switch SWB are provided as the switch SW.

[0060] FIG. 10 is a conceptual diagram showing state transitions of the first switch SWA and the second switch SWB in the first and second examples.

[0061] In the first example (FIG. 9(a)), the configuration of the operation knob 10 including the engagement groove 52 and the link member 19 including the engagement pin 53 are the same as those in the second embodiment (FIG. 7). The first switch SWA and the second switch SWB are arranged so that the timing at which they are pressed by the drive unit 19a is offset. For example, the second switch SWB is arranged further back in the plane of the paper than the first switch SWA, shifted to the left in FIG. 9(a).

[0062] During the forward stroke of the operation of the operating knob 10, the engaging pin 53 is driven by the engaging groove 52, the link member 19 moves leftward, and the driving portion 19a presses the first switch SWA and the second switch SWB in that order.

[0063] In a second example (FIG. 9(b)), two drive units 19a, drive unit 19aA and drive unit 19aB, are formed on link member 19. A first switch SWA and a second switch SWB are arranged in series in the moving direction of link member 19. The first switch SWA is driven exclusively by drive unit 19aA, and the second switch SWB is driven exclusively by drive unit 19aB. The first switch SWA and the second switch SWB are arranged so that the timing at which they are pressed by the corresponding drive unit 19a is staggered.

[0064] During the forward stroke of the operation of the operation knob 10, the link member 19 moves leftward, and after the drive section 19aA starts to press the first switch SWA, the drive section 19aB starts to press the second switch SWB.

[0065] Therefore, as shown in Figure 10, the state changes of the switches SWA and SWB are the same in both the first and second examples. Switches SWA and SWB are both OFF (non-conducting) Switch SWA is ON (conducting) and switch SWB is OFF Switches SWA and SWB are both ON Switch SWA is OFF and switch SWB is ON Switches SWA and SWB are both OFF The state changes sequentially to

[0066] In the first example (FIG. 9(a)), one driving section 19a functions as both driving section 19aA and driving section 19aB, unlike the second example (FIG. 9(b)).

[0067] 11 is a flowchart of the electrical component control process. The execution body and start conditions of this process are the same as those of the process in FIG.

[0068] In step S201, the control unit 101 determines whether or not the condition that the switch SWA has changed from an OFF state and the switch SWB has changed from an ON state to an OFF state has been satisfied. The control unit 101 continues the determination until the condition is satisfied, and if the condition is satisfied, the process proceeds to step S202.

[0069] In step S202, the control unit 101 starts the operation of the headlights 103. Therefore, essentially, the operation of the headlights 103 starts at the timing when the second switch SWB changes from ON to OFF during the forward stroke of the operation.

[0070] Next, in step S203, the control unit 101 determines whether or not the condition that the switch SWA is ON and the switch SWB is OFF has changed to the state where both the switches SWA and SWB are OFF has been satisfied. The control unit 101 continues the determination until the condition is satisfied, and if the condition is satisfied, the control unit 101 proceeds to step S204.

[0071] In step S204, the control unit 101 stops the operation of the headlights 103. Therefore, in effect, the operation of the headlights 103 is stopped at the timing when the first switch SWA changes from ON to OFF during the return stroke of the operation. After step S204, the control unit 101 returns to step S201.

[0072] According to this embodiment, it is possible to achieve the same effect as in the first embodiment in terms of maintaining the proper operation of the switch SW for a long time. Furthermore, it is also possible to determine whether the operation knob 10 has operated normally or whether it has returned to its original position during the forward or backward stroke.

[0073] In each of the above embodiments, the switch SW is equipped with a rubber contact 32, but this is not limited to this, and it may be any type of switch that returns to its original state when released from being pressed, such as a tactile switch.

[0074] While the present technology has been described in detail above based on preferred embodiments thereof, the present technology is not limited to these specific embodiments, and various forms within the scope of the gist of the present technology are also included in the present technology. Parts of the above-described embodiments may be combined as appropriate. [Explanation of symbols]
