Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a vehicle switch device for operating a constant speed traveling device.

(Prior Art) In recent years, the use of electronics in vehicles has been increasing, and for example, a constant speed traveling device that allows the vehicle to travel at a constant speed has been incorporated.

This constant speed traveling device is very convenient because it allows the vehicle to travel at any constant speed without operating the accelerator after reaching a predetermined speed on a highway or the like.

As a conventional switch circuit for operating such a constant speed traveling device, the one shown in FIG. 8 is known. (Page 136 of No. 578 B-136 of Kuchikata Jidosha's Published June 1988) In FIG. 8, the ignition switch 101 is connected to a battery power source (not shown). Further, the ignition switch 101 is connected to the constant speed traveling 61105 via the operation switch 103. The operation switch 103 has two operation knobs 107 and 10.
It has 9. When the operating knob 107 is pushed in after turning on the ignition switch 101, the contact 107a closes, so that the electric power IE from the battery is applied to the coil 111a of the relay 111 via this contact 1.7a. This closes the contact 111b of the relay 111, forming a self-holding circuit. That is, when the operating knob 107 is pushed in and released, the operating knob 107 is pushed in due to the elastic force of the spring 107b.
is returned to its original position, and contact 107a is opened. At this time, the contact 1°9a on the operation knob 109 side is closed. In this state, power E from the battery is applied to the coil 111a via the ignition switch 1o1 and the contacts 111b and 109a. Such a self-holding circuit causes the relay 111 to operate continuously, and power E from the battery is applied to constant speed running 61105 via the ignition switch 101 and contact 111b.

This constant speed traveling device 105 is for adjusting the quantity of fuel supplied to the engine according to a set speed, and setting the vehicle at a constant traveling speed.

To cancel such a constant speed running state, press operation knob 1.
This can be done by pushing in 09 to open contact 109a. When contact 109a is opened, the above-described self-holding circuit is no longer maintained and relay 111 is opened. As a result, the supply of N source to the constant speed traveling device ff105 is stopped, and the constant speed traveling state is released.

(Problems to be Solved by the Invention) By the way, the conventional example shown in FIG. 8 is equipped with a so-called fail-safe function to prevent the constant speed traveling device 105 from operating under conditions not intended by the driver. There is. That is, in order to operate the constant speed traveling device 105, the operation knob 1 is
When 07 is pushed in, the contact 107a in the closed state is closed, and when the operating knob 107 is released, the operating knob 107 is pushed back by the elastic force of the spring 107b, and the contact 107 is pushed back.
a is now open again. Therefore, while the constant speed traveling device 105 is operating, the ignition switch 101 is not operated to cancel the constant speed traveling state.
When only the ignition switch 101 is turned off and the imitation ignition switch 101 is turned on, the contact 107a
is in the closed state, so that the constant speed traveling device 105 is prevented from operating immediately.

However, while the conventional example shown in FIG. 8 can reliably prevent the constant speed traveling device from operating in a state unintended by the driver, it is provided with an operation knob 107 for operating the constant speed traveling device 105. In addition, this constant speed traveling device 1
An operation knob 109 must be provided for canceling the operation of 05, which poses a problem in that the degree of freedom in installing the operation switch 103 inside the vehicle is impaired.

Furthermore, since there is an operation knob 109 in addition to the operation knob 107, there remains room for further improvement from the viewpoint of operability.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a switch device for a vehicle that can improve the degree of freedom when assembling it into a vehicle, and can also improve operability.

Further, when the operation section is operated again, the engaged state at the lock position is released and the movable body 2 moves to the off position. Further, when the ignition switch is closed, opening of the second switch section causes the third switch section to open.
The closed state is maintained while the switch section is closed and the first switch section is closed, and when the first switch section is opened and the ignition switch section is closed. The closed state of the third switch section is released. Thus, the first switch section 4, the second switch section 6, and the third switch section 8 can be opened and closed by operating a single operation section.

When the movable contact piece 13 moves from the lock position [PB1 to the full stroke position apc1, the fixed contact pieces 15 and 17 are set in a conductive state. Further, the movable contact piece 21 sets the fixed contact pieces 23 and 25 in a conductive state only when the movable contact piece 21 moves to the full stroke position PC2.

Next, when you release your hand from the operating knob 7, the bushing rod 9 is pushed back by the locking groove portion, which will be explained later, and the movable contact pieces 13 and 21 are moved to the locked positions PB1 and PB, respectively.
It is set to lock at 2.

When the operation knob 7 is further operated, the above-mentioned engaged state is released by the lock release means, the bushing rod 9 is pushed back, and the movable contact pieces 13 and 21 are moved to the off position PA1, respectively.
It is designed to push back to PA2.

Next, the connection configuration between the operation switch 3 and its peripheral devices will be explained.

A contact 11b on the other side of the relay 11 is connected to the constant speed traveling device 5 and also to the fixed contact piece 15. Further, the fixed contact piece 17 is connected to the fixed contact piece 25 and the coil 1 of the relay 11.
It is connected to one side of 1a.

Further, the other side of the coil 11a is grounded.

Next, the structure and operation of an example of the heart cam described above will be explained in more detail with reference to FIGS. 3 and 4.

A τ cam portion 35 is incorporated into the frame 31 via a spring 33. A heart cam 29 as shown in FIG. 4 is incorporated into this cam portion 35. This heart cam 29 has a groove 39 along the outer periphery of the guide body 37 having a heart shape.
is formed.

A spacer 41 is attached to the cam portion 35 to which such a heart cam 29 is attached. The switch body 43 is @4
5, and a spring 47 is attached to this shaft 45.

The four drive bins that make up the moving body have a hole 49a and a guide rod 4.
9b, and after inserting the shaft 45 into the hole 49a, the drive bin 49 is fixed to the shaft 45 with a shaft stop ring 51.

The switch body 43 formed as described above is assembled into the frame 311 while being biased in the direction F1 by the spring 47. When the switch body 43 is pushed in the direction opposite to the direction F1 against the elastic force of the spring 47 in the direction F1, the guide rod 49b of the drive bin 49 moves to the heart-shaped guide body 37.

is the side wall portion P corresponding to the full stroke position shown in FIG.
It comes in contact with C, that is, it comes into contact with it and stops. If you let go of the operating knob 7 in this state, the spring 4
The switch body 47 is pushed back in the direction F1 by the resilient force of 7, and the guide rod 49b comes into contact with the side wall PB of the guide body 37 corresponding to the lock position shown in FIG. 1 and stops.

When the operating knob 7 is operated again in this state, the hooked state of the guide rod 49b to the side wall portion PB, that is, the engaged state is released, and the guide rod 491) is guided along the groove 39, that is, the spring The switch body 43 is pushed back in the direction F1 by the resilient force 47 and stops at a position corresponding to the OFF position shown in FIG.

Next, the operation of the embodiment shown in FIG. 2 will be explained.

When the operating knob 7 is pushed in after turning on the ignition switch 1, the movable contact piece 21 fixed to the bushing rod 9 moves to the full stroke position PC2, and the fixed contact piece 2
3 and 25 are electrically connected. As a result, the power source E from the valve is connected to the coil 11. of the relay 11 via the ignition switch 1 and the switch 27. supplied to a. As a result, the relay 11 operates and the contact 11b is closed.

Next, when the operating knob 7 is released, the bushing rod 9 is pushed back by the resilient force of the spring 47, and the movable contact piece 15 is locked at the lock position PB'1. In such an engaged state, the switch 19 is in a conductive state, and a self-holding circuit of the relay 11 is formed by this switch 19 and the contact 11b. Therefore, the relay 11 continues to operate, and electricity aE is supplied to the constant speed traveling device 5 via the contact 11b.

Thereby, the constant speed traveling bag M5 can be operated.

When the ignition switch 1 is turned off in such a state, that is, with the movable contacts 15 and 21 at the lock positions PB1 and PB2, respectively, the self-holding circuit of the relay 11 is cut off and the relay 11 is turned off. do. As a result, the power supply to the constant speed traveling device 5 is cut off.

Next, even if the ignition switch 1 is turned on again in the above-described state, that is, when the operation switch 3 is in the engaged state, the relay 11 continues to be in the off state because the switch 27 is open. This makes it possible to prevent the constant speed traveling device 5 from operating under conditions not intended by the driver.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 and 6.

The embodiment shown in FIG. 5 uses a solenoid 51 as a lock release means for releasing the engagement state of the operation switch 3, and also forcibly activates the solenoid 51 based on the output from the timer 55 when the ignition switch 1 is turned off. It is characterized in that it is activated to unlock the lock.

Specifically, as shown in FIG. 5(a), one end of a lever 53 as a moving body is connected to the shaft 45, and the other end of this lever 53 is fitted into a recess 57 of the frame 31. It has come to be called a multiplication. In this manner, when the other end of the lever 53 is engaged with the recess 57, the operation switch 3 is engaged in the lock position. The lever 53 is connected to a bushing rod 51a of a solenoid 51, and when the solenoid 51 operates, the bushing rod 51a moves in direction F2 and lifts the other end of the lever 53, as shown in FIG. 5(b). The engagement state between the lever 53 and the recess 57 is released.

As shown in FIG. 6, the timer 55 outputs a rectangular pulse signal when the ignition switch 1 is turned off, that is, when the ignition switch 1 is rotated from the ignition position, which is the contact point 1b, to the 7-way position, which is the contact point 1C. This pulse signal operates the solenoid 51 to release the engagement between the lever 53 and the recess 57. As a result, the operating switch 3 is released from the engaged state, and the resilient force of the spring 47 pushes the switch body 43 back to the off position.

As described above, in the embodiment shown in FIG. 5, when the ignition switch is turned off, the engaged state of the operation switch can be forcibly released based on the output from the timer. Therefore, even if the ignition switch is subsequently turned on again, it is possible to reliably prevent the constant speed traveling device from operating under a situation not intended by the driver.

Next, another embodiment of the present invention will be described with reference to FIG.

The embodiment shown in FIG. 7 is characterized in that when the ignition switch 1 is turned off without using a special device such as a timer, the solenoid is forcibly activated to release the engaged state of the operation switch. shall be.

In the embodiment shown in FIG. 7, a solenoid 51 is connected to the contact 1b of the ignition switch 1, and an appropriate terminal device 61 is also connected thereto. When the ignition switch 1 is turned off and rotated from the contact 1b which is in the ignition position U to the contact 1C which is the accessory position, the contact 1C and the contact 1d are electrically connected and the power supply current from the battery E is transferred to the contact. 1d, the contact 1C, the solenoid 51, and the terminal device 61. This allows the solenoid 51
is operated to forcibly release the engaged state of the operation switch 3.

As described above (the embodiment shown in FIG. 7), when the ignition switch is turned off without using a special device such as a timer, the engaged state of the operation switch can be forcibly released, further reducing costs. can be achieved.

Effects of the Invention As described above, according to the present invention, a plurality of switch sections can be opened and closed by a single operation section, and the engagement and disengagement of these switch sections can be performed using the above-mentioned operation section. Since this is done by operation, it is possible to improve the degree of freedom when installing it in a vehicle. Moreover, since the simple structure allows the vehicle switch to be closed once the ignition switch is opened, it is possible to improve the operability of setting and canceling operations in the low-speed traveling device, etc.
