The switch 31 is driven in an unlocked state. In addition, the main box 20 drives the door switch 31 in the locked state when the same signal as the unique ID stored within the predetermined time is not received, and is stored when the IG I or IG II of the ignition holder is detected or the vehicle door is opened. Even if the same signal as the unique ID is received, the wireless signal transmitted from the specific transmitter 10 is blocked. In the embodiment of Figure 1, the main box 20 is shown as being installed separately from the vehicle, but this is for convenience of description and the main box 20 is installed inside the vehicle.

The door lock motor 30 connected to the main box 20 is connected to the door switch 31 to drive the door switch 31 by a drive signal applied from the main box 20 to perform the opening and closing operation of the door. do. The ignition detection unit 40 is connected to the ignition holder (not shown). The ignition detection unit 40 determines the key position inserted in the ignition holder.

In addition, when the door open detection unit 70 detects whether the car door 33 is opened and determines that the car door 33 is opened, the specific door open / close signal transmission module 10 may receive the same signal as the stored unique ID. It controls to block the radio signal transmitted from.

3 is an internal configuration diagram of a transmitter provided in a battery for a mobile terminal according to the present invention. As shown in this figure, the transmitter 10 according to the present invention includes a CPU 13 and a radio transmitter 15. The transmitter 10 may perform an operation of opening and closing the car door 33 by using the power charged in the battery 1. The transmitter 10 is charged when the battery 1 supplies power, and then the battery is charged. A separate auxiliary power source for operating the transmitter 10 when all of the power in (1) is discharged may be further provided.

The CPU 13 stores the unique ID of the transmitter 10 in its own memory and controls to transmit a data signal including the unique ID periodically (for example, every 2 seconds). At this time, the CPU 23 incorporates a timer (not shown) to periodically control the transmission of data including the unique ID.

The wireless transmitter 15 constituting the transmitter 10 is connected to the CPU 13, and the oscillator 151, the phase locked loop 152, the loop filter 153, the voltage controlled oscillator 154 and the power amplifier 155 It is configured to include). The wireless transmitter 15 connected to the CPU 13 receives a unique ID registration start signal and a data signal applied from the CPU 13 to generate a radio frequency corresponding to each signal and transmit the radio frequency to the outside. At this time, the radio transmitter 15 is provided with a transmission antenna for transmitting the generated radio frequency to the outside.

The oscillator 151 constituting the wireless transmitter 15 is for generating a stable reference frequency (for example, 400 MHz), and the phase locked loop (PLL) 152 uses a reference frequency generated by the oscillator 151 to set a frequency. If the frequency is high or low, subtract or add the frequency so that there is no frequency change. In addition, the loop filter 153 constituting the wireless transmitter 15 filters the frequency synthesized in the phase locked loop 152 to minimize the phase error, and generates a precise variable frequency in the voltage controlled oscillator (VCO) 154. The power amplifier (PA) 155 amplifies the frequency generated by the voltage controlled oscillator 154 and outputs a signal having a constant amplitude to improve transmission efficiency. In addition, the wireless transmitter 15 feeds the output terminal of the voltage controlled oscillator 154 to the phase-locked loop 152 so that an error-free frequency is generated.

Here, when configuring the power amplifier 155, the offset voltage and the gain coefficient should be adjusted using a general amplifier to prevent the modulation of the waveform. It is necessary to adjust the offset voltage and the gain coefficient because the duty ratio is changed when the on / off signal of a different amplitude is determined by the same offset size.

4 is an internal configuration diagram of a main box according to the present invention. As shown in this figure, the main box 20 includes a wireless receiver 21, a CPU 23, a memory 25 and a control buffer 27. In addition, the main box 20 is connected to a regulator 60 for supplying a constant power to the main box 20 by using a car power source. The wireless receiver 21 is configured to connect the RF amplifier 211, the RF filter 212, the oscillator 213, the filter 214, the mixer 215, the SAW filter 216, the amplifier 217, and the IF IC 218. It is configured to include.

The radio receiver 21 demodulates and digitally converts a radio signal transmitted through the transmitter 10 into an original signal transmitted through a reception antenna. An RF amplifier (211) constituting the radio receiver 21 is to amplify to improve the reception strength of the radio signal input through the receiving antenna, the RF filter 212 to the RF amplifier 211 Filtered to pass only a frequency of a certain band of the amplified signal and to remove the other frequencies. In addition, the mixer 215 constituting the wireless receiver 21 converts the frequency filtered by the RF filter 212 and the frequency filtered by the filter 213 into a constant intermediate frequency, and includes a surface acoustic wave filter (SAW filter); 216 eliminates crosstalk and noise by passing only a frequency of a specific band at an intermediate frequency generated by the mixer 215. The amplifier 217 amplifies the intermediate frequency filtered by the SAW filter 216, and the intermediate frequency IC 218 demodulates the intermediate frequency amplified by the amplifier 217 into an original transmission frequency and converts it into a processable digital signal. do.

Here, the RF amplifier 211 constituting the wireless receiver 21 is preferably designed to operate even if a part of the circuit including the active element is not operating, the oscillator 213 oscillation output It is desirable to have sufficient and stable, low frequency content and simplify frequency adjustment. The amplifier 217 for amplifying the intermediate frequency may allow the designer to amplify the intermediate frequency high or low, depending on the device to be implemented. In the case of amplifying the intermediate frequency higher, the effect of the incoming phenomenon is improved and the characteristics of the transmission band frequency are improved.In the case of amplifying the intermediate frequency lower, the sensitivity and stability are improved, and the single adjustment is easy. There is an advantage that the selectivity is improved. Therefore, it is more preferable to implement to amplify the intermediate frequency low in the present invention.

On the other hand, the CPU 23 constituting the main box 20 is connected to the intermediate frequency IC 218, and reads the digitally converted frequency data to determine whether it is a registered ID, and according to the determined result the door lock motor ( It controls the operation of 30) and transmits various control signals indicative of the alarm output. In addition, after detecting a predetermined number of door pin operations, it serves to register an applied ID. The memory unit 25 is interconnected with the CPU 23, stores the unique ID of the specific transmitter 10 applied from the CPU 23, and stores the unique ID according to the unique ID extraction command of the CPU 23. It serves to apply to the CPU 23.

The control buffer 27 is connected to the CPU 23 and protects the CPU 23 from various signals input from an external device, and amplifies a control signal applied from the CPU 23 so as to drive the external device. It plays a role. The data block stored in the control buffer 27 detects a door lock signal for driving the door switch 31 in a locked state, a door unlock signal for driving the door switch 31 in an unlocked state, and a predetermined number of door pin operations. To generate information by using a door lock detection signal, an IG detection signal for detecting an IG I state or an IG II state by detecting a state of an ignition holder, a driving signal for driving a direction, a vehicle horn or a siren of its own Alarm generation signal for a unique ID, unique ID switching signal for switching the unique ID.

Hereinafter, the operation relationship for the door opening and closing of the vehicle using the transmitter 10 provided in the battery 1 for the mobile terminal of the present invention will be described in more detail with reference to the accompanying drawings.

First, the holder of the mobile terminal (1) equipped with the door open / close signal transmission module 10 according to the present invention, the main box 20 of the unique ID of the door open / close signal transmission module 10 installed in the mobile terminal 1 of the present invention. You must register at. To this end, when a unique ID switching signal set through the ID switching signal detection unit 80 connected to the main box 20 is input, the unique ID of the door opening / closing signal transmission module 10 is inputted to the main box 20. You can register.

Since the transmitter 10 transmits a radio frequency corresponding to a unique ID periodically while being supplied with power, the radio receiver 21 constituting the main box 20 receives the radio frequency and applies it to the CPU 23. do. However, all the radio frequencies transmitted from the transmitter 10 located within a predetermined range are applied to the CPU 23, but if the above-described unique ID registration start signal and a predetermined number of door lock detection signals are not detected, the radio frequency is ignored. On the other hand, since the unique ID data applied after the unique ID registration start signal and the predetermined number of door lock detection signals are detected, the unique ID is stored in the memory unit 25 because the unique ID is a regular unique ID that has undergone a correct unique ID registration process. . Therefore, the main box 20 is set to be operated only by the registered unique ID, and additionally, in order to register the unique ID according to the new transmitter 10, the main box 20 may be registered by performing the aforementioned unique ID registration process again. .

When the holder of the specific transmitter 10 enters within a certain range, the main box 20 receives the unique ID transmitted from the transmitter 10 and first determines whether the corresponding unique ID is a registered unique ID. If the unique ID is not a registered unique ID, the corresponding signal is ignored, and if the unique ID is registered, the door unlock signal is sent to the control buffer 27 to control the door lock motor 30 to be driven. When the door unlock signal is applied, the door lock motor 30 drives the door switch 31 to operate the door 33 in the open state. At the same time, the main box 20 sends a driving signal and an alarm signal to the control buffer 27 to notify the outside that the vehicle door is in an open state. For example, by driving the left / right direction light (for example, blinking twice) and generating an alarm sound (for example, two alarm sounds), the mobile unit battery 1 having the transmitter 10 is provided. The holder can easily recognize that the car door 33 is in the open state.

On the contrary, if the holder of the battery 1 equipped with the specific transmitter 10 deviates from a certain range (for example, 4m) (that is, if no radio frequency is detected from the specific transmitter 10), the main box 20 ) Transmits a door lock signal to the control buffer 27 to the outside of the vehicle door 33, considering that the holder of the battery 1 for the mobile terminal with the transmitter 10 is out of the vehicle. . For example, the holder of the battery 1 equipped with the transmitter 10 may drive a vehicle by driving a left / right direction light (for example, one blink) and generating an alarm sound (for example, one alarm). It is easy to recognize that the door 33 is locked.

In addition, when the driver sits in the driver's seat with the battery 1 provided with the transmitter 10, even if the door switch 31 is locked manually or automatically, the main box 20 may transmit the transmitter 10. Since the registered unique ID is continuously received, the door unlock signal is transmitted. Accordingly, when the holder of the battery 1 provided with the transmitter 10 is in the vehicle, the door unlock state continues. To solve this problem, when the IG detection signal is applied from the control buffer 27, the main box 20 ignores the signal even if a unique ID registered thereafter is received, thereby manually or automatically operating the door switch. When 31 is in the locked state, the door switch 31 is not driven in the open state to maintain the present state. In addition, when the driver is out of a certain range while the car door 33 is opened, the driver may maintain the current state without driving the car door 33 in the locked state even if the registered unique ID is not received. The IG detection signal is detected by the ignition detection unit 40 connected to the ignition holder, and the IG detection signal is detected when the driver rotates the key to the ON or ACC state while the driver inserts the key into the ignition holder.

The above descriptions are merely illustrative of one embodiment, and the present invention is not limited to the above-described embodiments, and various modifications can be made within the appended utility model registration claims. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

As described above, according to the battery for a mobile terminal with a transmitter according to the present invention, a battery holder for a mobile terminal with a transmitter having a transmitter for transmitting a wireless signal for opening and closing a car door without manually opening or closing the car door has a predetermined range. If the vehicle enters within, the door is automatically kept unlocked, and if the battery holder leaves a certain range, the door is automatically kept in the locked state, thereby automatically opening and closing the car door.

In addition, according to the battery for the mobile terminal of the present invention, when the holder of the mobile terminal equipped with the transmitter is in the driver's seat, the key position of the ignition holder is determined and the key is located in the IG state. By ignoring this, there is an effect of preventing the door switch from automatically unlocking during operation.

In addition, according to the battery for the mobile terminal, since the transmitter is operated using battery power, it is possible to reduce the trouble of installing or replacing a separate power supply unit.
