The present invention relates to a drive control circuit of a moving television receiver that enables a viewer to remotely control and move to a desired direction and location, or to adjust the viewing tilt angle and viewing angle freely and conveniently to view. In particular, the moving television receiver main body is separated into a head portion with a built-in CRT and a driving seat so that a signal selected from a corresponding mode key of a remote controller is received so that the CRT of the head is rotated at a left and right inclination angle on the driving seat. In the compartment of the driving seat, motor, chain, sprocket and gear are arranged on the axis of rotation so that the entire television receiver can be moved in any direction before, after, left and right through remote control. The vertical drive shaft, gears and motor are installed between the built-in head and the driving seat to perform remote control. A watch intended to provide a drive control circuit for moving a television receiver to be easily watched aligning the viewing angle is also freely along the viewing angle to the left, the user's location and viewing direction hameuroseo ever control in the right direction.

In general television receivers, the shape and shape of the TV receiver can vary, but the user can remotely control the TV receiver itself to move it forward, backward, left and right, or to incline the CRT to a certain inclination angle and to adjust the viewing angle. There was no television receiver, so if you want to change or move the television receiver to the viewer's position or viewing direction, lift the television receiver by hand or place it on a separate stand with wheels. It was used to push or pull the base by hand, which caused a lot of inconvenience, and in particular, the television receiver itself could not escape from the conventional concept of simply watching it in a certain position.

Therefore, consumers as well as manufacturers were eager for the emergence of television receivers that could feel a different image and atmosphere from the above conventional notions of television receivers.

In order to respond to this, it not only solves the inconvenience of using a general television receiver, but also breaks out of the conventional concept and forms an epoch for the television receiver. It is composed of the driving autonomous to adjust the inclination and the viewing angle in the right direction, and the driving seat having the driving device for the front, rear, left and right movement of the main body, and then the motor, the electromagnetic clutch, the various gears, the sprocket, the kinin, etc. And the head unit is connected and configured to move the television receiver itself consisting of the head unit and the driving seat unit to the front right and left sides while controlling and operating the internal motor and the electronic clutch by a remote controller, or, if necessary, the upper side of the driving seat unit. Rotate the head portion of the head upright by a certain angle in an upright state, or Tilt left and right by a certain inclination angle so that when the user or viewer moves away from the seat for a while, or when the television receiver itself is not visible at all, only the upper head of the driving seat can be left or right as a remote controller. Moving television receivers have been previously filed by US Patent No. 88-16345, which can be rotated in order to continuously watch, and also move forward or backward, or move left or right to allow continuous viewing at a visible position.

This motor and gear is built to provide the viewer's convenience by allowing the viewing direction to be adjusted freely in any place, but the present invention provides the tilt angle, the viewing angle and the front, rear, left and right of the tube of the moving television set configured as described above. The multiplexer, drive relay, and direction changer motor reverse, reverse, and speed are sequentially controlled by a single microcomputer with multiple output ports as the corresponding mode selection signal received from the remote controller. The CRT built into the head is combined with each other to lead to the controller and motor. The right inclination angle can be adjusted, but the switch to stop at a certain angle is implied, and the visual angle between the head part and the driving seat and the front and rear or left and right movement of the main body can be controlled more systematically by the present invention. The receiver itself is to provide a user's convenience by allowing the user (including the viewer) to freely adjust the desired position, angle and direction, which will be described in detail with reference to the accompanying drawings.

First, the moving television receiver 1 of the present invention is connected to a power source for viewing, and when the moving television receiver 1 is moved to the front, rear, left, or right directions according to the needs of the viewer, the power key of the television receiver is Relay ON (Ry1) of motor intermittent drive unit A10 which is turned ON and "H" start is output from the motor intermittent port of micom which is not shown in order to interrupt AC power supplied to each motor M1, M2, M3. As the coil is excited, the contact a and the contact a 'associated with each other are closed (CLoss).

At this time, the AC power is applied to the common a contact point of each motor driving unit A11, A12, and A13, and the power is applied to the common pin 1 of the speed controllers SC1, SC2, and SC3. You are in a waiting state.

In this state, the user selects the forward and backward movement motor selection button 37 "among the motor mode selection butters 37 ', 37", 37 "' on the remote controller 36 possessed by the user (viewer). When pressed, the signal is applied to the transistor Q4 through the diode D5, the resistor R5, and the capacitor C4 at the output port C of the microcomputer not shown, and at the same time, a separate supply power supply Vcc. The signals are applied to the transistors Q4 and Q5 through the power sources R6 and R7 to form an equipotential with each other, thereby inverting the signals to excite the relay Ry3 coil of the motor driver A12.

At this time, the AC power which has been waiting while the contact a of the relay Ry3 is closed is sent to the contact a of the relay 8 for electric drive Ry8.

Here, the user (viewer) moves the direction button of the remote controller 36 ( ) ( ) ( ) ( Direction movement button () When pressing), the output signal (G) of the microcomputer (not shown) and the supply power (Vcc) are applied to the nose of the forward driving relay (Ry7) through the limit switch (LM3) and are simultaneously excited. a 'contact is closed.

At this time, the power flowing to the contact a is applied to pin 2 of the speed controller Sc2 so that the power regulated by a variable resistor (not shown) in the speed controller Sc2 is connected to pin 3 of the speed controller Sc2 and the above. Fixing of the inner space compartment 15 of the lower driving seat 3 of the moving television receiver 1 while being transmitted to the forward terminal 01 of the motor forward / reverse switching circuit B11 through the a 'contact of the relay Ry7. The motor M2, which is fixedly installed below the diaphragm 16 and connected to the sprocket 23 " on the transmission side 19 and the chain 25, rotates.

At about the same moment, the electromagnetic clutch 22 on the drive shaft 20 is magnetically transmitted and power is transmitted. On the contrary, the electromagnetic clutch 22 'on the transmission shaft 19 falls by the magnetic force, and the motor M2 rotates in one direction. It is transmitted to the end sprocket 23 'on the lower transmission shaft 19 under the fixed plate 16 through the chain 25, and the transmission shaft 19 is driven together, and another sprocket built up on the previous coaxial shaft 19 ( 23 ') rotates and the sprocket 23 on the drive shaft 20, which is caught by the chain 25', rotates and the drive shaft 20 also rotates and is attached by the central electromagnetic clutch 22 to the drive clutch side ( 20 ') and the driving wheels 9 and 9' installed at both ends of the driving side 20 and the driving clutch shaft 20 'are driven while rotating in the same direction, so that the entire moving television receiver 1 is shown in FIG. As you see, you move forward.

At this time, when the moving television receiver 1 advances by the distance desired by the viewer, the pressed direction moving button on the remote controller 36 is pressed. When the signal is released, the signals output through the output port G of the microcomputer not shown are inverted, and thus the contacts a and a 'of the forward relay driver A16 and the relay Ry7 are opened to open the motor. The AC power supply to (M2) is cut off.

As a result, the forward movement of the moving television receiver 1 stops, and the electromagnetic clutch 22 ', which has been separated from the electric fan 19, is attached to its original state at the same time as the motor M2 stops.

In addition, the moving television receiver in the state in which the motor intermittent drive unit A10 operates normally and the multiplexer MP2 and the motor drive unit A12 operate according to a control signal output from the output port C of the microcomputer. When reversing (1), move the direction button on the remote controller 36 again. ), The signal is applied from the output port (H) of the microcomputer (not shown) to the transistor (Q11) of the reverse relay driver (A17) through the diode (D15), the resistor (R14), and the capacitor (C11). A separate supply power supply (Vcc) is applied to the relay (Ry8) coil through the limit switch (LM4), the coil is excited, and the contacts a, a 'are closed, and the AC power through the contact a is as described above. The power applied to the second pin of the speed controller Sc2 and regulated by a variable resistor (not shown) in the speed controller Sc2 is connected to the motor forward / reverse switching circuit (a) through the a 'contact of the relay Ry8. It is transmitted to the reverse terminal 02 of B11) and then applied to the motor M2.

At this time, in contrast to the above-described operation, the motor M2 installed on the upper surface of the fixed plate 16 of the interior space compartment 15 of the driving seat 3 reversely rotates, and at the same time, the electromagnetic clutch 22 on the driving shaft 20 is stuck. The transmission becomes possible, and the electromagnetic clutch 22 'on one side of the transmission shaft 19 falls again and the reverse rotation operation of the motor M2 is carried out through the chain 25 to the end of the transmission shaft 20 under the fixed plate 16. Drive shaft 20 configured to be transmitted to the sprocket 23 ″, which is installed on the driving shaft 20, and the driving shaft 20 is driven together while the other sprocket 23 ′ on one side of the driving shaft 19 is also rotated in a reverse direction and hung by the chain 25 ′. As the sprocket 23 rotates, the drive shaft 20 rotates in the opposite direction to the above-described operation.

In addition, since the driving clutch shaft 20 'is also attached by the electromagnetic clutch 22, the driving wheels 9 and 9' at both ends are operated while rotating in the same direction, so that the entire moving television receiver 1 is shown in FIG. As you can see back behind.

At this time, when the moving television receiver 1 is moved backward by the distance desired by the user (viewer), the pressed direction moving button on the remote controller 36 ( ), The signals output through the output port (H) of the microcomputer (not shown) are inverted so that the contacts a and a 'of the relay driver A17 and the relay Ry8 are open and The AC power supplied to the motor M2 is cut off.

As a result, the backward movement of the moving television receiver 1 stops, and the electromagnetic clutch 22 ', which has been separated from the transmission shaft 19, is reattached to the original state at the same time as the motor M2 stops.

In addition, the moving television receiver 1 in a state where the motor intermittent drive unit A10 operates and the multiplexer MP2 and the motor drive unit A12 normally operate by a control signal output from the output port C of the microcomputer.

In (D), a diode D7, a resistor R8, and a capacitor C6 are applied to the base of the transistor Q6 of the multiplexer MP3.

At the same time, a separate power supply Vcc is applied to the transistors Q6 and Q7 through the resistors R9 and R10 to form an equipotential with each other and the signals are inverted to relay the coil Ry4 of the motor driving unit A13. Let the girl

At this time, the AC power that has been awaited while the contact a of the relay Ry4 is closed is sent to the relay Ry9 a contact of the left driver A18 and the relay Ry10 a contact of the light driver A19.

In this case, the user (viewer) moves the light direction button of the remote controller 36 ( When pressing), the signal output from the output port F of the microcomputer (not shown) is applied to the light driver A19 through the diode D19, the resistor R16, and the capacitor C13, and at the same time, the limit switch LM10 coil In turn, the coil is excited and its a, a'contact is closed.

At this time, the AC power that has been awaited while the contact a of the relay Ry4 is closed is sent to the relay Ry9 a contact of the left driver A18 and the relay Ry10 a contact of the light driver A19.

In this case, the user (viewer) moves the light direction button of the remote controller 36 ( When pressing), the signal output from the output port F of the microcomputer (not shown) is applied to the light driver A19 through the diode D19, the resistor R16, and the capacitor C13, and at the same time, the limit switch LM6 is turned on. The supply power supply Vcc flows through the relay Ry10 coil, and the coil is excited to close its a and a 'contacts.

At this time, the a contact is closed and the AC power supplied from the relay (Ry4) a contact is applied to pin 2 of the speed controller Sc3 and simultaneously changed by a variable resistor (not shown) in the speed controller Sc3. The power is transferred to the reverse terminal 02 of the motor forward / reverse switching circuit B12 through the a 'contact of the relay Ry10 and then applied to the motor M3.

At this time, while the motor M3 installed on the upper surface of the fixed plate 16 of the inner space compartment 15 of the driving seat 3 reversely rotates, the electromagnetic clutch 22 on the drive shaft 20 drops at about the same moment, and the electric shaft ( The electromagnetic clutch 22 'on 19 is attached, and the reverse rotation of the motor M3 is transmitted to the transmission shaft 19 through the chain 25 so that the transmission shaft 19 rotates and the coaxial sprocket 23' is rotated. When the sprocket 23 of the drive shaft 20 hung with the chain 25 'is rotated to rotate the drive shaft 20, the drive wheel 9 of the biaxial end rotates clockwise.

At this time, the rotational motion on the transmission shaft 19 is again transmitted to the spear gear 24 'on the other clutch shaft 19' via the electromagnetic clutch 22 'on the shaft and engaged with the spear on the driving clutch shaft 20'. The gear 24 rotates in the reverse direction (counterclockwise) so that the driving clutch shaft 20 'is driven in the same direction while the other driving wheel 9' at the end rotates in the counterclockwise direction and is separated by the electromagnetic clutch 22. The driving shaft 20 and the driving wheels 9 and 9 'at both ends on the driving clutch side 20' are rotated in opposite directions to be rotated 360 degrees in the right direction, at which time the head of the moving television receiver 1 is moved. (2) rotates to the right and at the same time the direction button on the remote controller (36) held down when reaching the viewer's random selection ), The subsequent light driver A19 stops the operation by the signal output to the output port F of the microcomputer.

At this time, the downward movement button of the remote controller 36 ( When () is pressed, the relay Ry7 of the relay drive unit A16 for exclusive use of the inter-electric switch moves forward as the first forward operation in the state in which the head 2 of the moving television receiver 1 has turned to the right. As a result, the body of the moving television receiver 1 is moved to the right.

In this way, when the moving television receiver 1 is moving to the right by the desired distance, the direction moving button of the remote controller 36 held down ( In this case, the signals output through the output port G of the microcomputer are inverted as described above, and thus the a and a 'contacts of the forward relay driver A16 and the relay Ry7 are open. After that, the AC power supplied to the motor M2 is cut off.

Therefore, the right forward movement of the moving television receiver 1 stops and returns to its original state as the electromagnetic clutch 22 on the drive shaft 20 is attached.

In contrast to the above, when the moving television receiver 1 is moved to the left while the left and right moving motor selection buttons 37 ″ of the remote controller 36 are pressed, the left direction of the remote controller 36 is first left. Moving button ( When pressing), the signal output from the output port (E) of the microcomputer (not shown) is applied to the left relay driving unit (A18) through the diode (D17), the resistor (R15), and the capacitor (C12). Supply power Vcc through LM5 flows through the relay Ry9 coil to be excited to close its a, a, a 'contacts.

At this time, the contact a is closed and the AC power supplied from the contact point a of the relay Ry4 is applied to the number 2 pin of the speed controller SC3 and simultaneously changed by a variable resistor (not shown) in the speed controller SC3. The power is transferred to the forward terminal 01 of the motor forward and reverse switching circuit B12 through the a 'contact of the relay Ry9, and then applied to the motor M3.

At this time, the drive wheel 9 on the drive shaft 20 is rotated while the motor M3 having the transmission shaft 19 installed on the upper side of the fixed diaphragm 16 of the inner space compartment 15 of the drive seat 3 rotates forward. Rotate counterclockwise, and the other side drive clutch shaft 20 'and the drive wheel 9' rotate clockwise so that the head 2 of the moving television receiver 1 rotates 360 ° to the left. When the head 2 of the moving television receiver 1 rotates to the left and reaches the viewer's arbitrary selection angle, the direction shift button on the remote controller 36 held down ( ), The light driver A18 stops the operation by the signal output to the output port E of the microcomputer.

At this time, the downward movement button of the remote controller 36 ( When () is pressed, the relay Ry8 of the forward relay drive unit A17 is operated so that the head unit 2 of the moving television receiver 1 reverses in the reverse direction as described above while the direction of the head unit 2 of the moving television receiver 1 is rotated to the left side. As a result, the moving television receiver 1 is moved to the left.

In this way, when the moving television receiver 1 is moving to the left by the desired distance, the direction moving button of the remote controller 36 held down ( In this case, the signals output through the output port H of the microcomputer are reversed as described above, and thus the a, a 'contacts of the relay driver A17 and the relay Ry8 for the reverse are open. After that, the AC power supplied to the motor M2 is cut off.

Therefore, the left and the reverse movements of the moving television receiver 1 stop and at the same time, to move the moving television receiver 1 to the front while the moving television receiver 1 moves to the left and right, the direction movement button on the remote controller 36 ( ) ( The moving television receiver 1, which was facing left or right while pressing (), is charged to the left and right again.

Next, while watching the moving television receiver 1 of the present invention connected to a power source, in order to match only the upper head portion 2 of the moving television receiver 1 with the viewer's viewing angle (including the CRT tilt angle) according to the needs of the viewer. When rotating to the left or right by a certain inclination angle, as shown in FIG. 4, the viewer is located at the top of the motor mode selection buttons 37 ', 37 ", 37"' of the remote controller 36. When the left and right tilt angle adjustment motor selection button 37 'is pressed, the signal is connected to the diode D3, the resistor D3, the resistor R2, and the capacitor C2 at the output port B of the microcomputer not shown. Through the multiplexer MP1.

At the same time, a separate supply power source Vcc is applied to the transistor Q2 and the transistor Q3 of the motor driver A11 through the resistors R3 and R4 to form an equipotential with each other, thereby inverting the signal to the motor driver A11. The relay (Ry2) of the coil is excited.

At this time, the AC power which has been awaited while the contact a of the relay Ry2 is closed is sent to the relay RY5 a contact of the left driver A14 and the relay Ry6 a contact of the light driver A15.

At this time, the user (viewer) moves the direction button of the remote controller 36 ( ) ( ) ( (▽) direction movement button ( When pressing) is applied to the transistor (Q9) of the light driver (A15) through the diode (D11), resistor (R12) and capacitor (C9) in the output coat (F) of the microcomputer not shown, a separate supply power ( Vcc) is applied to the relay Ry6 coil through the limit switch LM2 and the coil is excited and the contacts a, a 'are closed, and the AC power through the contact a is connected to pin 2 of the speed controller SC1. Power applied and regulated by a variable resistor (not shown) in this speed controller SC1 is transmitted to the reverse terminal 02 of the motor forward / reverse switching circuit B10 through the a 'contact of the relay Ry6. After it is applied to the motor (M1).

At this time, the motor M1 fixed to the rotating disc 29 on the vertical transmission shaft 26 of the moving television receiver 1, the lower driving seat 3, the inner space compartment 15 of the moving television receiver 1 rotates counterclockwise, The small sprocket 23c fixed to the shaft rotates and is caught by the chain 25 " 'so that the sprocket 23 " " installed between the two fixing pieces 28, 28 " rotates counterclockwise.

At the same time, the chain rack 32 which is integrally fixed to the head fixing semicircular piece 31 and the lower surface of the lower part of the head 2 while being engaged with the sprocket 23 "" rotating counterclockwise is sprocket 23 "". When the gear moves along the rotation of the moving part and rotates to the left side, the head part 2 of the upper part of the moving television receiver 1 is rotated inclined to the right as a result.

At this time, the protruding locking pieces 33, 33 'at both ends of the head fixing semi-circular piece 31 are pivoting rollers 30, 30', 30 " (30 " ') above the lower fixing pieces 28, 28'. As shown in FIG. 3, the head fixed semicircular piece 31 of the head fixed semicircular piece 31 is smoothly operated by preventing the shaking of the head fixed semicircular piece 31 during the inclined rotation operation of the head part 2. It also serves as a sliding guide.

In this way, while the head portion 2 is tilted to the right at the desired angle, the direction movement button on the remote controller 36 was pressed. ), The signal output through the output port (f) of the microcomputer is inverted so that the contacts a, a 'of the light driver A15 and the relay Ry6 are open, and then the motor M1 is opened. ) Will cut off the AC power.

Therefore, the motor M1 stops driving and at the same time the tilting and tilting operation of the head 2 is stopped, so that the user can watch only the upper head 2 of the moving television receiver 1 by a predetermined inclination angle as desired. Will be.

However, due to the mistake of the user, the direction movement button (on the remote controller 36) Even if you keep pressing), the inclined inclination angle of the head part 2 can be kept within 20 ° (the inclination angle can be adjusted according to the limit switch installation position). Limit switches LM1 and LM2 are provided at positions away from each other so that the head part 2 is inclined to the set inclination angle (20 °) by the rotation of the motor M1 and the head fixing semicircular piece 31 and the chain rack ( The limit switch LM2 is quenched by spherical sliding of both ribs 6 and 6 'fixing 32. As shown in FIG.

As a result, the contact point of the limit switch LM2 is opened to move the direction button of the remote controller 36 ( ) Is pressed, the power supplied to the coil of the relay Ry6 is cut off by the limit switch LM2 operation.

Therefore, the motor M1 is stopped while not receiving the necessary power, thereby controlling the inclination of the head 2 of the moving television receiver 1 by 20 ° or more to the right.

However, the limit switches LM1 and LM2 fixed to the support covers 4 and 4 'have an inclined angle of 20 ° to 60 ° when the fixed position is changed on the support covers 4 and 4'. You will be able to watch by tilting the angle of inclination to the right within the range.

On the contrary, when only the head 2 of the moving television receiver 1 is tilted to a certain angle to the left by the viewer's need, the left and right inclination angle adjustment motor selection buttons 37 'of the remote controller 36 are viewed. When pressing the direction movement button (◁) on the left side while pressing the signal, the raft drive unit A14 through the diode D9, the resistor R11 and the capacitor C8 at the output port E of the microcomputer not shown. A separate supply power supply (Vcc) is applied to the relay (Ry5) coil through the limit switch (LM1) while being applied to the transistor (Q8) of the c), the coil is excited and at the same time close the a, a 'contact, a AC input power through the contact is applied to pin 2 of the speed controller SC1 so that the power regulated by a variable resistor (not shown) in the speed controller SC1 is connected to the motor through the a 'contact of the relay Ry5. Positive and reverse switching circuit (B10) After the transfer to the forward terminal (01), it is applied to the back motor (M1). At the same time, the motor M1 fixedly installed on the rotating disc 29 on the vertical transmission shaft 26 of the moving television receiver 1, the lower driving seat 3, the inner space compartment 15 of the moving television receiver is clockwise as opposed to the above-described operation. Rotation of the motor M1 through the small sprocket 23c and the chain 25 "'on one side, and the two fixing pieces 28 integral with the upper rotation disk 29 of the transmission shaft 26 ( The lower surface of the head fixing semi-circular piece 31 fastened to the lower surface of the head portion 2 of the moving television receiver 1 through the sprocket 23 "'provided between 28') is transferred to the chain rack 32, 32 is rotated to the right in accordance with the rotation operation of the sprocket 23 "'so that the head portion 2 of the moving television receiver 1 is rotated inclined to the left side.

In this state, when the head 2 is inclined at the inclination angle desired by the viewer, the direction movement button of the remote controller 36 held down ( ), The signal output through the output port (E) of the microcomputer (not shown) is inverted and the relay Ry5a, a 'contact of the left driving unit A14 is opened to open the motor (M1). ) Will cut off the AC power.

Therefore, the motor M1 stops driving and at the same time the inclined tilting operation of the head 2 is stopped, so that only the upper head 2 of the moving television receiver 1 is inclined at a predetermined angle to the left. You can tilt and watch.

In this case, the maximum inclination angle of the head 2 can be safely viewed by the limit switch LM1 fixedly installed at a predetermined position of the support cover 4 so as not to deviate beyond a predetermined inclination angle range.

In addition, the operation of the motor intermittent drive unit A10 means that the motor intermittent button 37 of the remote controller 36 is pressed, and at the same time, the relay of the motor intermittent drive unit A10 by the signal output from the output port A of the microcomputer. (Ry1) The coil is excited to supply AC input power to each of the motor driving units A11, A12, and A13, and in this state, the motor mode selection buttons 37 'and 37 "of the remote controller 36 are supplied. (37 "') and the direction shift buttons (▷) (△) (▽) can be used to control each motor drive device of the moving television receiver 1.

However, if the motor intermittent button 37 of the remote controller 36 is returned to its original position, the relay a1a of the relay Ry1 is opened because the relay Ry1 coil of the motor intermittent drive unit A10 does not operate. The AC input power supplied to the motor driving units A11, A12, and A13 is cut off.

Therefore, as described above, the moving television receiver 1 of the present invention can be moved forward, backward, left, or right in a place and direction desired by the viewer, and only the upper head portion 2 of the moving television receiver 1 can be used. Can be watched by rotating left and right as much as the viewing angle in the desired direction, and if necessary, only the head part 2 of the moving television receiver 1 can be tilted so as to tilt the left and right angles so that it can be watched at home. When watching a moving TV receiver in the kitchen, go to the kitchen to eat and continue to watch the moving TV receiver, you can move it to a place you want by remote control and control circuit. Tilt only the upper head to a certain inclination angle or to the desired viewing angle Not only is it convenient to use, but it is also very convenient to use, and it gives a different image that users can move arbitrarily or adjust the tilt angle and the viewing angle, which the general television receiver itself was simply able to watch while being placed in a certain place. It is an innovative design that can achieve a new era for television receivers.
