Definitions

  • the present invention relates to a motor antenna device for use with vehicles wherein a motor antenna is lifted and projected outside the vehicle or car when a power source for electronic appliances such as the radio receiver, for example, mounted in the car is switched on and wherein it is lowered and housed in the car body when the power source is switched off.
  • a power source for electronic appliances such as the radio receiver, for example, mounted in the car is switched on and wherein it is lowered and housed in the car body when the power source is switched off.
  • the power source for accessories is switched off during the time when the engine starter is to be made operative, for the purpose of making small the load for the battery. Therefore, the motor antenna is lowered because the power source for the radio receiver is switched off. When the engine starter is made operative, the antenna is again lifted because the radio power source is switched on.
  • the present invention provides a motor antenna device for use with an antenna rod and arranged to lift or lower the antenna rod, the device being adapted for connection to a power source and comprising: a motor capable of rotating in a forward direction and a reverse direction; a driving mechanism comprising a damper coupled to the motor and adapted to be coupled to the antenna rod whereby to transfer rotational force from the motor to the antenna rod to lift or lower the antenna rod; motor driving circuitry comprising motor polarity changeover circuitry connected in series with the motor and arranged to control the direction of current flow from the power source through the motor; motor lock detector connected in series with the motor and arranged to detect the current flowing through the motor when it is mechanically locked; and motor control circuitry arranged to cause the disconnection of the motor from the power source when a motor lock state is detected by the lock detector; characterized in that: the motor driving circuitry further comprises a motor driving device responsive to the motor control circuitry connected in series with the motor polarity changeover circuitry and arranged to turn on or off the current flowing through the motor;
  • a preferred embodiment of the present invention provides a motor antenna device for use with vehicles as defined above having a logic circuit which enables the motor antenna to be appropriately operated, associating with the power source for electronic appliances such as the radio receiver mounted in the vehicle.
  • Fig. 1 is a circuit diagram showing a case where the present invention is applied to the motor antenna for the radio receiver.
  • Battery 11 is earthed at the low voltage side thereof and connected at the high voltage side thereof to one end of starter switch 12 which is associated with the engine key.
  • Starter switch 12 has an ACC (accessories) terminal, to which the power source terminal of radio receiver 10 is connected. Voltage at the other end RX of the radio power source becomes "H” (high) in level when a radio switch (not shown) is turned on and “L” (low) in level when the radio switch is turned off.
  • Input terminals of three-second timer 20 and antenna raising or lifting trigger circuit 32 are connected to terminal RX of radio power source and an input terminal of antenna lowering trigger circuit 31 is connected to an output terminal of three-second timer.
  • Three-second timer 20 includes a resettable multi-vibrator and serves to output signal "H” when voltage at terminal RX of radio power source is “H” level and output signal "H” for three seconds after voltage at terminal RX of radio power source becomes “L” level.
  • Antenna lowering trigger circuit 31 generates a trigger when the output signal of three-second timer 20 falls.
  • Antenna lifting trigger circuit 32 generates a trigger when signal applied from terminal RX of radio power source rises.
  • Motor polarity changeover circuit 40 changes over the polarity of antenna motor M with respect to that of the battery 11 so as to lift the motor antenna when antenna lifting trigger circuit 32 generates a trigger, but it changes over the polarity of antenna motor M so as to lower the motor antenna when no trigger is generated through circuit 32.
  • Motor power source changeover and control circuit 50 is connected in series to antenna motor M and serves to supply power to motor M when antenna lifting or lowering trigger circuit 32 or 31 generates a trigger signal. MOtor power source changeover and control circuit 50 also detects current increase in motor M and stop power supply to motor M when the top of the motor antenna reaches its uppermost or lowermost point.
  • Three-second timer is an example of the means for stopping the lowering of the motor antenna for a predetermined time after the radio power source is switched off.
  • Fig. 2 is a circuit diagram showing the above-described embodiment of the present invention in more detail.
  • Motor polarity changeover circuit 40 includes relay 41, transistor (2SC2458, for example) 42 connected in series to relay 41, and contact 43 of relay 41.
  • Contact 43 has two points of contact and when they are connected to terminal U, motor M is rotated in forward direction to lift the motor antenna but when they are contacted with terminal D, motor M is rotated in reverse direction to lower the motor antenna.
  • Motor power source changeover and control circuit 50 inciudes drive transistor (2SC686, for example) 51 connected in series to motor M, positive characteristic temperature/resistance element 52 such as posistor connected to the emitter of transistor 51, NAND gate 53 and RS flip-flop (F/F) 54.
  • Transistor 51 allows current to be supplied to motor M when flip-flop 54 is set.
  • Flip-flop 54 is set at the rising or falling of signal outputted from three-second timer 20 and re-set when NAND gate 53 generates a negative pulse.
  • inverter 61 for inverting the output signal of three-second timer 20, condenser 62 and resistor 63, while the falling of the output signal of three-second timer 20 (or falling of the output signal through terminal RX of radio power source) is detected by condenser 64 and resistor 65.
  • 0.2-second timer 71 generates a negative pulse of 0.2 second when the output signal of three-second timer 20 rises or falls and this negative pulse of 0.2 second serves to set flip-flop 54 and prevent flip-flop 54 from being re-set by rush current of motor M.
  • Ten-second timer 81 generates a negative pulse for ten seconds after the output signal of three-second timer 20 rises or falls, and condenser 82 generates a positive pulse when the output signal of ten-second timer 81 rises.
  • This positive pulse forcedly re-sets flip-flop 54 through NAND gate 53 to stop power supply to motor M even if element 52 generates no predetermined voltage when motor M is locked.
  • AND gate 91 and transistor (2SC2458, for example) 92 for stabilizing power source are further included.
  • AND gate 91 serves to turn on transistor 42, excite relay 41 and connect contact 43 to terminal U while three-second timer 20 generates signal "H" and flip-flop 54 is set.
  • Fig. 3 is a time chart showing the operation of the above-described embodiment.
  • Output Q of flip-flop 54 is "H” and the output signal of three-second timer 20 is also “H” in this case. Therefore, the output signal of AND gate 91 becomes “H”, transistor 42 is turned on, relay is excited, contact 43 is connected to terminal U and antenna motor M is rotated in such a direction (or direction shown by an arrow in Fig. 2) as to lift the motor antenna.
  • Transistor 51 is thus turned off to stop current supply to motor M.
  • Output Q of flip-flop 54 becomes “L” at this time. Therefore, the output of gate 91 also becomes “L”, transistor 42 is turned off, relay 41 is not excited and contact 43 is connected to terminal D.
  • the lifting and lowering of the motor antenna are repeated responsive to on and off of terminal RX of radio power source, as described above.
  • the engine stops, for example, while the motor antenna is being lifted, and when starter St is turned at t11, terminal RX of radio power source is turned off and the input voltage of three-second timer 20 becomes "L".
  • the engine is usually started in three seconds. Therefore, the time of holding starter St turned is also three seconds or less.
  • starter ST is turned back at t12
  • t13 at which delay time td in the rising of signal through terminal RX of radio power source has passed from t12 is usually in three seconds from time t11. Therefore, the output signal of three-second timer 20 is held "H” even at t13.
  • the output of gate 91 is thus kept “H", transistor 42 is turned on and motor M is kept rotating in forward direction.
  • Timer 20 has been set three seconds in the above-described embodiment, but it may be set from 2 to 10 seconds. Any means except the resettable multi-vibrator may be used instead of three-second timer 20 to prevent the antenna from being lowered for a predetermined time after the power source of the radio receiver is switched off. Further, timers 71 and 81 may be set any seconds different from 0.2 and 10 seconds.
  • a control device simple in construction and kept normal even when the starter is rendered operative, wherein two control lines for detecting the states of the ignition and the accessories are not needed as the signal line for controlling the motor antenna and the control circuit for calculating the logical condition is not needed too.
  • motor current increases rapidly at the moment when the motor is locked. It is therefore difficult to accurately detect the motor current at this moment and accurately stop the motor at a current value set.
  • Another embodiment of the present invention which will described below includes a system for lifting and lowering a rod antenna, a shock absorber arranged between the antenna lifting and lowering system and a motor for driving the system to damp mechanical shock, and a means for generating a voltage to meet motor current.
  • the shock absorber damps mechanical shock between the antenna lifting and lowering system and the motor.
  • the value of voltage to meet motor current is gradually increased in the voltage generator means.
  • motor locking current can be accurately detected, thereby preventing motor current from being wasted at the time when the motor is locked.
  • Fig. 4 shows a rod antenna system.
  • the lower end of the smallest diameter section of telescopically extensible rod antenna 100 is connected to the top of rack rope 105, which is engaged with gear 104.
  • Rack rope 105 is longer than the one shown in Fig. 4.
  • Gear 111 is attached to the rotating shaft of motor M and a coil spring 113 which serves as s shock absorber is arranged between gears 112 and 104.
  • Control box CB houses a control circuit such as circuits 40 and 50 in Fig. 1 to control the rotation of motor M.
  • Rack rope 105 and gear 104 are an example of the system for lifting and lowering rod antenna 100 and motor M is an example of the means for driving this system.
  • Coil spring 113 is an example of the shock absorber for damping mechanical shock between the system and motor M.
  • Fig. 5 shows motor current changing while motor M is started and stopped.
  • Fig. 6 is a diagram showing an example of the control circuit housed in control box CB.
  • the circuit comprises NAND gate 120, R-S flip-flop 54, AND gate 122 serving as a circuit for preventing transistor circuit 51 from being put on, transistor circuit 51 for driving motor M, positive characteristic temperature/resistance element (which will be hereinafter referred to as PTC) 52 connected in series to motor M, resistors 125 and 126 for adjusting bias at one input terminal of NAND gate 120, and diode 127 for similarly shifting bias.
  • PTC is an example of the means for generating voltage corresponding to motor current.
  • the circuit further includes inverter 131 for inverting the signal of ACC, NAND gate 132 for causing signal "0" to be generated when the starter is activated, gate 141, NOR gate 142 and gate 143.
  • Gate 141 has a function of its being not delayed when signal changes from “1” to “0” but delayed when signal changes from “0” to “1” and it has also another function of inverting signal.
  • NOR gate 142 causes a negative pulse to be generated when the power source of radio receiver RX is switched on and off.
  • Gate 143 is a monostable multi-vibrator for causing a negative pulse (or pulse of signal "0") to be generated every time when the power source of radio receiver RX is switched on and off and when the starter is rendered operative.
  • the width of this pulse is set about 0.1 seconds or others by means of resistor 144a and condenser 144c.
  • Transistor 42 excites relay 41 and contact 43 serves as the one for relay 41.
  • contact 43 is connected to terminal U, motor M is rotated in forward direction and rod antenna 100 is lifted.
  • relay 41 is not excited, contact 43 is connected to terminal D, motor M is rotated in backward direction and rod antenna 100 is lowered.
  • Gates 120, 122, flip-flop 54 and transistor circuit 51 form an example of the means for stopping motor M when current for motor M reaches a predetermined value.
  • PTC serves as a means for generating such a voltage as increases almost linearly.
  • Fig. 7 is a time chart for showing the operation of the above-described embodiment.
  • Rod antenna 100 is thus gradually lifted.
  • motor M continues to rotate in forward direction (for a time period denoted by t2 in Fig. 5).
  • gear 104 begins to stop
  • spring 113 begins to serve as the shock absorber since then, rotation speeds of gears 112, 111 and motor M reduce gradually and motor current rises gradually (at a time period shown by t3 in Fig. 5). Therefore, voltage rises gradually at both ends of PTC 52 and becomes higher than the predetermined value at T3 in Fig. 7 and voltage becomes higher than the threshold value at input terminal 120d of NAND gate 120. Since a positive signal is applied to input terminal 120U of NAND gate 120 at this time, NAND gate 120 outputs a negative signal and flip-flop 54 is re-set.
  • AND gate 122 thus outputs a negative signal and transistor circuit 51 is rendered inoperative. Motor M stops its rotation at this time.
  • gate 143 When the power source of radio receiver RX is then switched off (at T4 in Fig. 7), gate 143 generates a negative pulse and gate 144 also generates a negative pulse for 0.1 seconds from when the negative pulse of gate 143 rises.
  • Flip-flop 54 is thus set again to make transistor circuit 51 operative. Since the power source of radio receiver RX is switched off this time, transistor 42 is turned off and relay 42 is not excited. Therefore, contact 43 is connected to terminal D and motor M is rotated in backward direction. Rod antenna is thus lowered gradually.
  • gear 104 begins to be mechanically locked.
  • Spring 113 serves again as the shock absorber this time and gears 112, 111 and motor M reduce their speeds gradually.
  • gate 120 When current for motor M increases gradually and voltage also increases gradually at both ends of PTC 52 and becomes higher than the predetermined value (at T6 in Fig. 7), gate 120 generates a negative pulse, flip-flop 54 is reset, transistor circuit 51 is put off, and motor M is stopped.
  • Shock absorber 113 is arranged between rod antenna 100 and motor M as described above. Even when the top of rod antenna 100 reaches its uppermost or lowermost point, therefore, motor current rises not rapidly but gradually and lock current for motor M can be thus detected accurately. It is therefore not caused that a large amount of motor current continues to flow at the time when motor M is locked.
  • the shock absorber may not be spring 113 but a clutch may be employed.
  • a comparator is located before NAND gate 120 to detect whether or not voltage exceeds the threshold value
  • motor current can be accurately detected when the motor for the motor antenna is locked. This prevents motor current from being wasted at the time of motor lock.
  • Fig. 8 is a circuit diagram showing a further embodiment of the present invention.
  • This circuit in Fig. 8 is different from the one shown in Fig. 6 in that timer 150 and gate 157 are added.
  • Timer 150 comprises resistors 152, 153, 156, condensers 154, 155 and AND gate 151.
  • This timer 150 is an example for stopping motor M through the motor stopping means after a predetermined time period, longer than a time period during which the top of rod antenna 100 moves from its uppermost point to its lowermost point or from its lowermost point to its uppermost point, has passed since motor M is started.
  • Gate 157 serves to turn on transistor 42 after the power source of radio receiver is switched on but within a time period set on timer 150.
  • Transistor 42 excites relay 41.
  • Transistor 42 is an example to excite relay 41 for the time period set on timer 150.
  • Fig. 9 is a time chart showing the operation of the embodiment.
  • Timer 150 outputs a negative signal within a time period set on it but a positive signal during another time period which is except the time period set on it, and the time period set starts at T1. Since timer 150 outputs a negative signal and gate 141 also outputs a negative signal at T1, gate 157 outputs a positive signal and transistor 42 is put on at T1 when the power source of radio receiver RX is switched on. Relay 41 is excited this time, contact 43 is contacted with terminal U, motor M is rotated in forward direction, and rod antenna starts its lifting and locked similarly when the top of rod antenna 100 reaches its uppermost point.
  • timer 150 outputs a positive signal (at T1) when the time period set on timer 150 lapses. Therefore, flip-flop 54 is re-set, transistor circuit 51 is put off and motor M is forcedly stopped.
  • Timer 150 starts its counting at T4.
  • timer 150 In a case where rod antenna 10 is locked with its top held at its lowermost point and the circuit for detecting motor current is out of order, timer 150 outputs a positive signal (at Tt1) when the time period set on timer 150 lapses. Therefore, flip-flop 54 is re-set, transistor circuit 51 is put off and motor M is forcedly stopped.
  • transistor 42 excites relay 41 only for the time period set on timer 150. Therefore, power is used only for the time period set on timer 150, thereby preventing power from being wasted.
  • the motor antenna is automatically lifted or lowered when the power source of the radio receiver is switched on or off.
  • the power source of an antenna driving motor is shut off when the top of the antenna reaches its uppermost or lowermost point, that voltage applied from the engine key is supplied to the control circuit at a neutral position of an antenna lifting/lowering switch to cause the antenna to be moved by the antenna lifting/lowering switch only when the engine key is turned on, and that antenna housing movement is done by a trigger when the engine key is turned off, said trigger serving to make zero those inputs which are applied to the control circuit.
  • Fig. 10 is a circuit diagram showing this embodiment of the present invention.
  • the circuit includes engine key 211, battery 212, switch 220 for lifting and lowering a motor antenna (not shown), relay 231 having contacts 230, motor M for driving the motor antenna, transistor 241 for controlling motor current, positive characteristic temperature/resistance element 242 connected in series to transistor 241, NAND gate 243, flip-flop 244 and circuit 250 for generating gate pulses.
  • Element 242 is an example of the means for detecting that the top of the motor antenna has reached its uppermost or lowermost point while the antenna is being lifted or lowered.
  • Flip-flop 244 and transistor 241 are examples of the means for shutting off the power source of the antenna driving motor when the top of the antenna reaches its uppermost or lowermost point.
  • relay 231 When lifting and lowering switch 220 is contacted with terminal U, relay 231 is excited to connect contacts 230 to terminals U, thereby causing motor M to be rotated in such a direction that the motor antenna is lifted.
  • the exciting of relay 231 is stopped to switch contacts 230 to terminals D, thereby causing motor M to be rotated in such a direction that the motor antenna is lowered.
  • flip-flop 144 When engine key 211 is turned off, keeping lifting and lowering switch connected to terminal N, flip-flop 144 is set to put on transistor 241. Gate 243 generates a re-set pulse to re-set flip-flop 244 because the voltage of element 242 becomes higher than a predetermined value when lifting and lowering switch is connected to terminals U or D, motor M is rotated, and the top of the motor antenna reaches its uppermost or lowermost point.
  • Transistor 241 allows current to be supplied to motor M when flip-flop 244 is set, and it shuts off the power source of motor M when flip-flop 244 is re-set.
  • Gate pulse generator circuit 250 prevents re-set pulses from being applied to flip-flop 244 even when voltage becomes higher than the predetermined value at both ends of element 242 because of rush current, in order to prevent the malfunction of the circuit caused by rush current at the time of motor start.
  • Fig. 11 is a circuit diagram showing the above-described embodiment in more detail.
  • Operation panel 301 is provided with a diode arranged between lifting and lowering switch 220 and ACC and a diode arranged lifting and lowering switch 220 and IG. Other components except operation panel 301 and motor M are housed in control box 302. 0.2-second timer 51 is also included as a circuit used instead of gate pulse generator circuit 250.
  • Fig. 12 is a time chart showing the operation of this embodiment.
  • Engine key 211 is turned on at t0 when lifting and lowering switch is at neutral position (or connected to terminal N).
  • the motor antenna can be automatically housed only by pulling the engine key out of the key hole. Therefore, the housing of the motor antenna can be easily carried out when the driver comes outside out of the car. Further, current to motor M is automatically stopped in this case when the top of the motor antenna reaches its lowermost point, thereby preventing motor M from being burned.
  • 0.2-second timer 251 generates a negative pulse for 0.2 seconds. Therefore, gate 243 generates no negative pulse to mistakenly re-set flip-flop 244.
  • the time period set on timer 251 is not limited to 0.2 seconds but it may be longer or shorter then 0.2 seconds.
  • Fig. 13 shows a variation of the operation panel shown in Fig. 11.
  • Two interlock switches 224a and 224b are used instead of lifting and lowering switch 220 which has the neutral contact, and resistor 223 and diode 225 are arranged between these two interlock switches.
  • This arrangement of two interlock switches 224a and 224b is intended to achieve same function as that attained by lifting and lowering switch 220.
  • control means for lifting and lowering the motor antenna through the lifting and lowering switch can be made simple in construction, prevent the motor from being burned, and cause the antenna to be automatically housed when the engine key is pulled out of the key hole or turned off.
