Description

remote control transmitter

technical field

The present invention relates to a remote control transmitter mainly used for remote operation of video or audio, air conditioning equipment, etc. in a car. the

Background technique

In recent years, with the promotion of high functionality and diversification of automobiles, video, audio, air-conditioning equipment, etc. have been introduced into automobiles. The operation part is provided on the panel, and the introduction of remote control transmitters for operating these devices from a distance such as the rear seat away from the panel is also advancing. the

In this way, the remote control transmitter used in the car sometimes falls under the seat or is hidden in the gap between the center console and the seat or the like. For example, Japanese Unexamined Patent Application Publication No. 2000-22562 discloses a remote control transmitter having a notification unit that notifies the position by a predetermined operation even in such a case so that it can be easily found. the

A conventional remote control transmitter will be described using FIG. 4 . Fig. 4 is a front view of a conventional remote control transmitter. An operation unit 22 is provided on an upper surface of a substantially box-shaped casing 21 made of insulating resin. The operation unit 22 has a plurality of keys protruding so as to be movable up and down, and switch contacts (not shown) are provided under the keys. Inside the housing 21, a wiring board (not shown) on which a plurality of wiring patterns are formed is accommodated on the upper and lower surfaces. A control unit (not shown) is formed by electronic components such as a microcomputer mounted on the upper and lower surfaces of the wiring board. Furthermore, the transmission unit 24 is formed by electronic components such as light emitting diodes connected to the wiring board. the

Furthermore, an antenna, a buzzer, and the like are mounted on this wiring board, and a receiving unit and a reporting unit (both not shown) are formed by these, thereby constituting a remote control transmitter. the

Such a remote control transmitter is mounted on a vehicle. Moreover, when a predetermined key of the remote control transmitter is pressed and operated from a rear seat far away from the panel, the switch contacts at that position are electrically connected, and the control unit detects these operating states. The predetermined keys are, for example, the key 22A for turning on/off the power, the key 22B for switching the volume, and the like. In addition, infrared remote control signals corresponding to these are transmitted from the transmitting unit 24 to the device, and for example, on/off of audio or air conditioner, volume increase and decrease, etc. are remotely operated. the

When the remote control transmitter falls under the seat or is hidden in a gap between the center console and the seat, etc., it is not known where it is located. In such a case, the user operates a predetermined switch (not shown) provided on a panel or the like. Then, for example, an antenna (not shown) installed near an indoor lamp or the like transmits a radio wave including a search signal. When the receiving part of the remote control transmitter receives the search signal, the buzzer of the notifying part sounds to notify its position. Thus, the user can easily find the remote control transmitter. the

In addition, when any key of the remote control transmitter, for example, the key 22A is pressed and operated, that is, when a certain passenger uses the remote control transmitter, the control unit stops the notification unit. That is, in the case of performing such a normal remote control transmitter remote operation, even if another passenger operates the search switch by mistake, the receiving unit receives the search signal, and the notifying unit does not operate. the

In this way, in the conventional remote control transmitter, when any key is pressed and operated, even if a search signal is transmitted, the notification unit does not operate. Therefore, when a heavy object is placed on the remote control transmitter, or the remote control transmitter is sandwiched between seats, etc., and several keys are pressed, the position cannot be confirmed and it is difficult to find it. the

Detailed ways

FIG. 1 is a block circuit diagram of a remote control transmitter according to an embodiment of the present invention, and FIG. 2 is a front view thereof. An operating unit 2 is provided on an upper surface of a substantially box-shaped casing 1 made of insulating resin such as polystyrene or ABS (acrylonitrile-butadiene-styrene) resin. The operation unit 2 has a plurality of keys made of rubber or insulating resin protruding so as to be movable up and down, and switch contacts (not shown) are provided on the lower surfaces of the keys. the

Inside the housing 1, a wiring substrate (not shown) such as paper phenol or glass epoxy, on which a plurality of wiring patterns are formed by copper foil or the like, is accommodated on the upper and lower surfaces. The control unit 10A is formed of electronic components such as a microcomputer mounted on the upper and lower surfaces of the wiring board. The transmission unit 4, the reception unit 5, and the notification unit 6 are also provided on the wiring board. The transmitting unit 4 includes electronic components such as light emitting diodes, and transmits remote control signals. The receiving unit 5 includes an antenna and the like, and receives a search signal to be described later. The notification unit 6 includes a buzzer, a motor, etc., and generates at least one of sound and vibration. That is, the control unit 10A is connected to the operation unit 2 , the transmission unit 4 , the reception unit 5 , and the notification unit 6 . The control unit 10A operates the transmission unit 4 according to the operation of the operation unit 2 , and operates the notification unit 6 according to the operation of the operation unit 2 and the search signal received by the reception unit 5 . In this way, a remote control transmitter is formed. the

Such a remote control transmitter is mounted on a vehicle. Furthermore, when a predetermined key of the remote control transmitter is pressed and operated from a rear seat far away from the panel, the switch contacts at that position are electrically disconnected, and the control unit 10A detects these operating states. The predetermined keys are, for example, the key 2A for turning on/off the power supply, the key 2B for switching the volume, and the like. In addition, infrared remote control signals corresponding to these are transmitted from the transmitting unit 4 to the equipment, for example, audio or air conditioner power on/off, volume increase and decrease, etc. are remotely operated. the

Furthermore, when the remote control transmitter falls under the seat or is hidden in a gap between the center console and the seat, etc., it is not known where it is located. In such a case, the user operates a predetermined switch (not shown) provided on a panel or the like. Then, for example, a radio wave search signal is transmitted from an antenna (not shown) installed near an indoor lamp or the like. When the receiving unit 5 of the remote control transmitter receives the search signal, the control unit 10A notifies its position by generating sound, vibration, etc. through the buzzer and motor of the notifying unit 6 . Thus, the user can easily find the remote control transmitter. the

In addition, when any key of the remote control transmitter, such as the key 2A, is pressed, the control unit 10A detects the operation state of the operation unit 2, and the notification unit 6 is in a stopped state. This is the state of a passenger using the remote control transmitter. In other words, when it is considered that only one key is pressed and operated, and the operation of the normal remote control transmitter is carried out, even if other passengers mistakenly operate the switch for searching, the receiving part 5 receives the search signal, and the notifying part 6 does not respond. action. the

On the other hand, when a plurality of keys 2C, 2D, etc. are pressed simultaneously, such as when a heavy object is placed on the remote control transmitter or sandwiched between seats, the control unit 10A detects these operating states. Such a state is different from normal remote operation. And, when receiving part 5 receives search signal, control part 10A produces sound and vibration etc. by buzzer and motor etc. of reporting part 6. the

In this way, the control unit 10A detects that the remote control transmitter is in an abnormal operation state other than normal operation through the operation of the operation unit 2 , and operates the notification unit 6 according to the search signal received by the receiving unit 5 in the case of abnormal operation. Furthermore, even when the operation unit 2 is not operated, the notification unit 6 is operated based on the search signal received by the reception unit 5 . Furthermore, in the case of normal operation, the notification unit 6 is not activated. the

In other words, in the state where only one key is pressed and operated in normal remote operation, the notification unit 6 stops. On the other hand, when a heavy object is placed on it or is sandwiched between the seats, and a plurality of keys are pressed simultaneously, when a search signal of an electric wave is sent from the vehicle body side, the remote control transmitter makes the notification unit 6 act and notify its location so that it can be found. Here, a plurality of keys that are pressed at the same time due to heavy objects, seats, etc. are generally close to each other. Therefore, when a plurality of adjacent keys such as keys 2C and 2D are pressed, it is preferable that the notification unit 6 operates. the

In addition, in the state where the notification unit 6 is activated by pressing the plurality of keys 2C, 2D, etc., when the key 2E etc. close to them is pressed and operated, the notification unit 6 maintains the activated state. On the other hand, when the key 2F etc. located away from these are operated, 10 A of control parts stop the notification part 6. As shown in FIG. Such a structure is preferred. the

When the heavy object placed on the remote control transmitter moves a little, or gets further caught between the seats, the key 2E, etc. which is close to the key 2C, 2D pressed so far is pressed and operated. In such a case, in the configuration described above, the notifying unit 6 maintains an operating state for notifying the position. On the other hand, when the key 2F at the remote position is operated when a heavy object is removed or pulled out from between the seats, the notification unit 6 is stopped and the normal remote operation is resumed. When the keys near the corners on the casing 1, such as the keys 2C and 2D, are operated, operate the key 2F at a position opposite to the diagonal of the face of the casing 1 on which the operation portion 2 is arranged, or for the casing 1 1's longitudinally opposite position of key 2B. In such a case, it is preferable to stop the configuration of the notification unit 6 . Also, when a key near the center of the surface of the case 1 on which the operation unit 2 is provided, such as key 2G or 2H, is operated, a key near the corner of the case 1, such as key 2A or key 2B, is operated. In such a case, it is preferable to stop the configuration of the notification unit 6 . the

In this way, in the remote control transmitter of this configuration, the control unit 10A detects the operating state of the operation unit 2 . Furthermore, when the receiving unit 5 receives a search signal in a state where at least two keys of the operating unit 2 are simultaneously operated, the notifying unit 6 is operated. Thereby, even if a heavy object is placed on it or it is sandwiched between the seats, the remote control transmitter can be easily confirmed and easily searched for. the

Furthermore, in a state where a plurality of keys are operated and the operation unit 6 is operating, if a key located away from them is operated, the control unit 10A stops the operation unit 6 . Thereby, it is possible to return the remote control transmitter to a state where normal remote operation is performed after finding it from a state where it was pressed by a heavy object or a seat. the

Next, a remote control transmitter having another configuration according to the embodiment will be described. Fig. 3 is a block circuit diagram of another remote control transmitter according to the embodiment of the present invention. The appearance of this remote control transmitter is the same as that in FIG. 2 . The difference from the remote control transmitter shown in FIG. 1 is that instead of the control unit 10A, a control unit 10B having a timer 9 that generates a clock signal at predetermined intervals by a crystal oscillator or the like is provided. The configuration other than that is the same as that in FIG. 1 , so description thereof will be omitted. the

In the above configuration, when only one key is pressed and operated during normal remote operation, the operation is the same as that of the configuration in FIG. 1 . Moreover, in the state where the remote control transmitter is unknown and the key of the operation part 2 is not pressed, the user operates a predetermined switch to transmit a radio wave search signal from the antenna so that the notification part 6 notifies the operation of the position. same. the

In addition, when a key of the remote control transmitter is pressed and operated, it is the same as that the control unit 10B detects the operation state of the operation unit 2 and does not operate the notification unit 6 . At this time, in this configuration, the control unit 10B counts the operation time of the keys of the operation unit 2 using the timer 9 . If the operation is continued within the predetermined time and the operation is completed within the predetermined time, the control unit 10B puts the notification unit 6 in an operation standby state. the

For example, when the operation ends after the key 2B is pressed for 5 seconds, the control unit 10B does not operate the notification unit 6 . Then, when the key 2A or the like is pressed, the control unit 10B starts counting the operation time of the key 2A using the timer 9 . The key 2A is continuously operated for more than or equal to a predetermined time, such as around 10 minutes. In this state, when the receiving unit 5 receives a search signal for a position search, the control unit 10B makes the buzzer and the buzzer of the reporting unit 6 and motor etc. That is, the control unit 10B detects that the remote control transmitter is in an abnormal operation state other than the normal operation by the operation of the operation unit 2 . Based on the search signal received by the receiving unit 5, the notifying unit 6 is operated at least in the case of an abnormal operation. the

In other words, when the key is only pressed for a predetermined time and the normal remote control transmitter is operated remotely, even if other passengers mistakenly operate the switch for the search and the receiving unit 5 receives the search signal, the control unit 10B will not receive the search signal. Make the reporting unit 6 act. On the other hand, the control unit 10B activates the notification unit 6 when the pressing operation of one key continues for more than ten minutes or more than the normal operation. the

When a heavy object is placed on the remote control transmitter or it is sandwiched between seats, the key 2A or key 2B is continuously pressed for a predetermined time, unlike the key operation during normal remote control. In this state, the control unit 10B detects these operating states, and when the receiving unit 5 receives the search signal, the buzzer and the motor of the notifying unit 6 generate sounds, vibrations, and the like. In this way, the remote controller transmitter notifies its location, and the user can find the remote controller transmitter. the

In addition, for example, when the key 2D is kept pressed and the key 2C or 2E close thereto is pressed and operated, the notification unit 6 remains in the activated state. On the other hand, when the key 2B, 2F, or the like located away from the key 2D is operated, the control unit 10B stops the notification unit 6 . The description of this structure is also the same as that of the structure of FIG. 1 . That is, when the keys near the corners of the housing 1, such as the key 2D, are continuously operated for a predetermined time or longer, the key 2F at the diagonally opposite position to the surface of the housing 1 on which the operation unit 2 is installed is operated, Or for the key 2B at the longitudinally opposite position of the casing 1 . In such a case, it is preferable to stop the configuration of the notification unit 6 . And, when the keys near the center of the surface of the housing 1 on which the operation unit 2 is provided, for example, the key 2G is continuously operated for a predetermined time or longer, the keys 2A, 2B, and 2C near the corners of the housing 1 are operated. , one of 2F. In such a case, it is preferable to stop the configuration of the notification unit 6 . the

In this manner, according to this configuration, control unit 10B detects the operating state of operation unit 2 . Then, when one of the keys in the operation unit 2 is continuously operated for a predetermined time and the receiving unit 5 receives a search signal, the notification unit 6 is activated. Thereby, even when a heavy object is placed on the remote control transmitter, or it is sandwiched between seats, etc., the position can be easily confirmed and the remote control transmitter can be easily found. the

Furthermore, in this configuration, the timer 9 is incorporated in the control unit 8, but it may be configured separately. the

As mentioned above, the remote control transmitter of the present invention is easy to confirm the location and easy to find, and is mainly used for remote operation of video, audio, and air-conditioning equipment of automobiles. the
