Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic small telephone control device that is installed in an automobile together with car components such as a car radio, car stereo, etc.

[Conventional technology]

With the development of mobile telephone communication networks in recent years, automobile telephones installed in automobiles have become widely known.

With such a car telephone, for example, the receiver is removed from the telephone body and the receiver is held to make a call, just like a normal home telephone.

When a driver uses such a car telephone, the general rule is to stop the car in a safe place and make calls while the car is parked. For example, at the time of transmission, it is sufficient to transmit after stopping the car in a safe place, so there is no problem. However, if the vehicle is received while driving, it may not necessarily be possible to stop immediately due to current traffic conditions. For example, if the driver attempts to respond while the vehicle is still moving, the driver will be forced to take one hand off the steering wheel and drive with one hand until it is safe to stop. This makes driving difficult, and
The driver's concentration becomes distracted, which is not desirable. Also,
Depending on the operating state, it may not be possible to respond.

Therefore, hands-free type car telephones have been made available that allow telephone calls to be made without having to hold the handset. A hands-free car phone, for example, is equipped with a handset stand that has a microphone and a speaker that corresponds to the handset, and by placing the handset on the handset stand, you can make calls using the external microphone and external speaker installed inside the car. configured to be possible. With this configuration, even when the driver is talking on the phone, he is not forced to drive with one hand and can temporarily drive to a safe location.

Furthermore, car components such as car radios and car stereos are widely installed in automobiles to add entertainment elements to driving in automobiles.

[Problem to be solved by the invention]

As mentioned above, in the known car telephone device, the handset is placed on the handset stand, and calls are made via an external microphone extended to the driver's mouth and an external speaker appropriately placed inside the car. It is done.

However, in a configuration in which a separate external microphone is provided, the external microphone is provided, for example, on two sides of the dash board, on the ceiling, etc., and is used by being extended to the driver's mouth during a call. In other words, the position where the external microphone is disposed is often within the driver's field of vision, which is not preferable because the driver cannot concentrate on driving and may obstruct the driver's field of view.

The external microphone is used by extending from the installation position to the driver's mouth. Therefore, depending on the location of the external microphone, the external microphone may interfere with the driver's driving operation, which is not preferable.

Furthermore, if other sounds, such as audio from the car component, are output during a call, it will interfere with the call. in this case,
When talking on a car phone, it is necessary to turn off the car component or turn down the volume. However, the driver must operate a switch on the car component every time he or she makes a call using the car phone, which is undesirable because the driver's concentration becomes distracted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a car telephone control device that allows a user to make a call without having to hold a receiver, and that automatically sets a good call environment during a call.

[Means to solve the problem]

In order to achieve this object, the present invention has a handset detection means for detecting the presence or absence of a handset of a car telephone, and also has a mouthpiece of the handset, a transmitting speaker corresponding to the earpiece, and a receiving microphone. Equipped with a telephone receiver.

Then, when the handset detection means detects that the handset is placed,
The pair of side headrests are swung to the call position, and the call microphone is swung to the call position, so that the call environment can be set.

Further, by detecting the handset by the handset detecting means, the output sound 7'f from the pillow speaker can be switched to a car telephone.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 and 2, the one-component vehicle telephone control device 10 according to the present invention has a telephone receiver stand 14 equipped with a telephone receiver detecting means lz, a pillow speaker 18 built in a side headrest 16, It is configured to include a microphone 2G, a headrest motor 22, a telephone microphone motor 24, and a central processing unit 26.

As shown in FIGS. 2 and 3, the handset stand I4 is formed such that a handset 28 of a car telephone can be placed thereon, for example.
The receiver microphone 30 corresponds to the earpiece 211a of the handset and receives sound from the earpiece, and the transmitting speaker 32 corresponds to the earpiece 28b and outputs the sound from the microphone 18. . As shown in FIG. 2, the receiver microphone 30 and the transmitter speaker 32 are connected to a receiver amplifier 34
The receiving microphone is connected to the relay contact 36 of the output audio control relay 36, which will be described later, from the receiver amplifier.

Moreover, as can be clearly seen from FIG. 3, the telephone receiver stand 14 is
It has a hook 40 on which the handset 28 can be placed, and the hook is
The rod 42 extending from the lower end is slidably inserted into the insertion hole 44 of the handset base, and is attached to the upper end of the handset base. For example, a presser plate 46 is attached to the middle part of the rod 42.
is fixed to the return spring 4 made of a tension coil spring or the like.
δ is wrapped around the rod below the retainer plate and within the handset base. The receiver detecting means 2 is disposed at a position where the lower end of the rod 42 can be suppressed. In such a configuration, the hook 40 is normally biased in the opposite direction under the biasing force of the return spring 48. Further, when the receiver 28 is placed on the hook 4G, the hook is lowered together with the rod 42 against the eccentric force of the return spring 4δ, and the lower end of the rod presses the receiver detecting means 12.

As the handset detecting means 12, for example, a hook switch consisting of an automatic return button switch, a pressure sensor, etc. can be used, and the hook switch is connected to a central processing unit 28, as shown in FIG. Then, placement of the handset on the handset base 14 is detected by a signal sent from the handset detecting means (hook switch) 12 to the central processing unit 26 .

The central processing unit 26 is formed with a microcomputer 50, which processes input according to a stored program and generates appropriate control signals. For example, when the telephone receiver 28 is placed on the hook 4o and the central processing unit 26 detects the presence of the telephone receiver by a signal from the hook switch I2, the control signal is transmitted to the central processing unit 28 as shown in FIG. Motor control relay 52.54.56 connected to the unit

56a, 36a, and 36b are appropriately switched to control the driving of the headrest motor 22, the telephone microphone motor 24, and the sound of the pillow speaker 1δ, respectively.

As shown in FIG. 2, the pillow speaker 8 is connected, for example, to the relay contact 35a of the output audio control relay 36, and by switching the relay contact 36a, the car component (car component) consisting of the car radio 58, car stereo GO, etc. ) 62 and the voice from the telephone microphone 20.

For example, it is assumed that when the sound of the car combo 62 is being output from the pillow speaker Iδ, the output sound control relay 3G is energized by a signal from the central processing unit 26, and the relay contacts 36a and 36b are respectively switched. Then, this relay contact 36a.

By switching 36b, the pillow speaker 18 and the receiver microphone 30 are connected via the receiver amplifier 34, and power from the battery 38 is supplied to the receiver amplifier 34, and the sound output from the pillow speaker is transmitted to the receiver. The audio is switched to from 28.

Further, as shown in FIG. 4, a neck seat detection means 64 for detecting whether the driver is seated is disposed within the notebook cushion 68 of the driver seat 66. Seating detection means 64
For example, a seat switch consisting of a pressure sensor or the like can be used, and as can be seen in FIG. 1, the seat switch is connected to the central processing unit 26. For example, when the head seat switch (head seat detection means) 64 detects the driver's pressure, a signal is output to the central processing unit 2G, and the signal from the central processing unit energizes the motor control relays 52 and 54, and the headrest motor 22
The drive is controlled.

The headrest motor 22 is disposed within the headrest main body 70 at the upper end of the seat back, and the swinging of the side headrest 16 is controlled by driving the headrest motor. The side headrest drive mechanism 72 including the headrest motor 22 is roughly configured as follows.

As can be seen from FIG. 5, for example, the side frame l-78 has extensions rJ78a and 80a on its extension line, and the side frame δ0 has extensions rJ78a and 80a on a perpendicular line, respectively, and the connecting shirt l-111 is attached to each extension end. Both ends of the left and right side frames 78 and 80 are pivotably connected to each other so as to be interlockable. Here, for example, the lower end of the side frame 78 is configured to include a friction plate 82 that is integrally rotatable.

Further, a bracket 84 is installed on the stay 76, and the headrest motor 22 is attached to the bracket via a motor bracket δ6. The headrest motor 22 has a friction plate δ8 that can be interlocked with the m-diaphragm o of the side frame, and the headrest motor is arranged so that the friction plate 88 of the headrest motor comes into contact with the friction plate 82 of the side frame. has been done.

In such a configuration, the rotation of the friction plate 8δ of the motor as the headrest motor 22 is driven causes the friction plate 8δ to rotate.
The side frame 78 is swung in the front-rear direction integrally with the side frame 8o, and the side frame 8o is also swung accordingly.

Here, a limit switch (LSI) 90. which limits the swing range of the side frame. (+, 52)92. ([,

For example, the limit switch (+, 5t) 9G, which regulates the vibration of the 7th
As shown in the figure, the retracted position of the side headrest I6 is settable, and when the side headrest swings outward from the riding position and the limit switch (LSI) is turned on, the headrest motor 22 stops. , the retracted position of the side headrest is set. Further, the limit switch (LS2) 92 is configured to be able to set the riding position of the side headrest 16 as shown in FIG. Then, when the side headrest is swung from the retracted position of the side headrest 16 as shown in FIG. 7 or the talking position of the side headrest as shown in FIG. 9 and the limit switch (LS2) 92 is turned on, the headrest The motor 22 stops, and the riding position of the side headrest is set. Furthermore, limit switch (LS3

It is connected to the relay contact 36a of the car combo 62 or the car phone, and is configured to be able to output audio from either the car combo 62 or the car phone by switching the relay contact.

Further, as shown in FIG. 2, a changeover switch lOσ is provided to change over the audio output to the pillow speaker 18 during a call. The changeover switch 10G is provided in a bypass manner with respect to the relay contact 36g of the output voice control relay 36, and is configured to be switchable only when the relay contact of the output voice control relay is switched to the telephone side. By switching the selector switch 100, the tLl force of the pillow speaker 18 can be appropriately selected from either the left or the right. According to this configuration, the output sound during a call can be selected according to the driver's preference, so the situation outside the vehicle can be judged by sound without being interfered with by the sound from the pillow speaker during a call. Howling caused by the position of the telephone microphone 20 can also be prevented. Therefore, it is possible to prevent the driver's concentration from decreasing while driving. Note that the changeover switch 100 is preferably placed in a position where the driver can operate it, for example, in a console box or the like.

Note that reference numeral 1G2 in FIG. 1 indicates an overcurrent detection resistor that detects overcurrent to the headrest motor 22.

The operation of the automobile telephone control device 1o configured as described above will be explained along the time chart of FIG. 10.

For example, when the driver is seated on the driver seat 66 and the seat switch 64 detects that the driver is seated (FIG. 10(A)) when the side headrest 16 is in the retracted position shown in FIG. 28 energizes the motor control relay 52 with a delay of ΔT1 second,

)).

During a telephone conversation, the handset is placed on the hook 40 of the handset base 14, and when the hook switch I2 detects the handset (FIG. 50(B)), the motor #II control relay 52
is energized, and the relay contact 52a is switched (10th
Figure (C)). Then, by switching the relay contact 52a, the seat rest motor 22 is driven in the normal rotation direction (Fig. 1O (E)), and the side head rest 16 is
It is further swung inward from the riding position shown in the figure.

At this time, as shown in FIG. 10 ([), the output sound output filter IF, II control relay 36 is also energized, and the relay contacts 36a and 36b are switched from the car combo 62 side to the telephone side (first O (J), the input signal of the receiving microphone 30 is output from the pillow speaker 18.

Here, as can be seen from FIG. 10(G), when the signal of the hook switch 12 is generated, for example,
After a second delay, the motor control relay 56 is energized, the relay contact 56a is switched, and the telephone microphone is swung from the storage position to the telephone position (see Figure 9) (Figure 10 (11)).
. Then, when the side headrest 16 swings inward from the riding position and the limit switch (LS3) 94 is turned on (FIG. 10(F)), the headrest motor 22 is stopped, and as shown in FIG. , the side headrests are set to the talking position.

When the call is over and the handset 28 is removed from the hook 40 of the handset stand, and the hook switch 12 no longer detects that the handset is placed and turns off (FIG. 1O (B)), a signal from the central processing unit 26 , motor control relay 54
is energized, and the relay contact 54a is switched (10th
Figure (D)). Then, by switching the relay contact 54a, the headrest motor 22 is driven in the reverse direction (
10(E)), the side headrest 1G is swung outward from the talking position of FIG.

Then, the headrest motor 2z reverses until it is regulated by the limit switch (1, 32) 92, and when the limit switch (LSD) is turned on, the headrest motor is stopped (10th Q (E)) and the side headrest 16 is set at the riding position shown in FIG.

At this time, at the same time as the hook switch 12 is turned off, the motor control relay 56 is energized (FIG. 1O (G)), and the relay contact 56a is switched. Then, relay contact 56a
As a result of this switching, the call microphone motor 24 is driven, and as shown in FIG. Figure 10 (II)).

In addition, by turning off the hook switch 12, FIG. 1O (
1), the output audio control relay 36 is also energized, the relay contact 36a is switched from the car phone side to the car combo 62 side, and the output audio from the pillow speaker 18 is switched to the audio from the car component ( Figure 1O (J
)).

When the driver gets out of the vehicle, the driver lifts his or her hips off the driver seat 66 and presses the seat switch 66.
When the driver no longer detects the pressure of the screwdriver, Fig. 1θ (A
)), a signal from the central processing unit 26 immediately energizes the motor control relay 54 and closes the relay contact 36a.
is switched (Fig. 1O (D)). Then, by switching the relay contact 36a, the headrest motor 22
is driven in the reverse direction (Fig. 1O (E)), the side headrest 16 is swung outward from the riding position, the headrest motor 22 is driven until it is regulated by the limit switch (LSI) 90, and the side headrest 16 is swung outward from the riding position. The headrest is immediately set to the retracted position of FIG.

In this manner, the side headrest 16 immediately moves to the retracted position when the driver simply lifts his/her hips, allowing the driver to get out of the vehicle without being obstructed by the side headrest. Furthermore, even when the driver gets out of the vehicle, the side headrests 16 are waiting at the retracted position, so the driver can get on the vehicle without being obstructed by the side headrests.

As mentioned above, the car telephone control device 1 according to the present invention
According to 0, Hookswitch! 2 detects the receiver 28, the output audio from the pillow speaker 18 is automatically switched from the car component 62 to the telephone. Therefore, there is no need to operate a switch to adjust the volume of the car component 62, and the user can easily talk on the phone without being disturbed by the sound If of the car component.

Further, when the hook switch 12 detects the receiver 28,
By driving the headrest motor 22 and the call microphone motor 24, a good call environment is automatically set.

In other words, the driver only needs to place the handset 28 on the hook 40 of the handset stand and can talk without having to hold the handset, so he is not forced to drive with one hand. Therefore,
Even if you receive calls while driving, you can easily make calls without interfering with safe driving.

The telephone microphone 20 is normally stored below the side headrest lIi, and is swung to the telephone position only during a telephone conversation. Therefore, the driver can perform normal driving operations during a call without being interfered with by the call microphone 20.

Furthermore, since the telephone microphone 20 is swingably attached to the side surface of the side headrest 1G, it does not interfere with the driver's forward vision, driving operation, etc.

Further, when the driver gets on and off the vehicle, the side headrest 16 is automatically swung to the retracted position, so the driver can smoothly get on and off the vehicle without being obstructed by the side headrest.

In the embodiments, the car phone has a main body and a handset that are separate, but the present invention is not limited to this, and can also be applied to, for example, a handset in which the dial part and the handset are integrated. In addition, in the embodiment, the receiver detection means! 2, the receiver 2δ can be detected, and the seating detection means 64 can detect the seated person, and the communication environment is automatically set by detecting the receiver and the seated person.
