Fig. 2 is the schematic illustration of the tunable built-in antenna mould group of intelligent door lock disclosed in this invention.
Drawing reference numeral explanation:
101- antenna body, 102-RFCable line, 103- net mate device, 104- power amplifier.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention are explicitly described, it is clear that described embodiment is of the invention one
Section Example, rather than whole embodiments.Based on the embodiment of the present invention, this field general technical staff is not making wound
Every other embodiment obtained shall fall within the protection scope of the present invention under the premise of the property made labour.
It is as shown in Figure 1 the tunable built-in antenna mould group 100 of smart lock disclosed in this invention, comprising: antenna body
101, RFCable lines 102, net mate device 103, power amplifier 104；Entire antenna modules 100 are set to intelligent door lock gold
Belong to the interior surface of shell.
Net mate device 103 is connect by RFCable line 102 with antenna body 101.
Power amplifier 104 is connect with net mate device 103.
Net mate device 103 is provided with π type match bit, π type match bit it is in parallel with after capacitor C2 ground connection after being grounded by C1 and
Series inductance L1 is constituted between the capacitor C1 and the capacitor C2, so that the signal pins to antenna are adjusted, makes antenna
Resonance frequency within the scope of suitable, guarantee the normal of antenna impedance, to improve the communication performance of antenna.
In the present embodiment, antenna body 101 is that flexible circuit board design is constituted, and uses micro- sharp laser carving straight forming day
Line is more preferably provided with grounding point in antenna body 101, this grounding point is with copper area.
In the present embodiment, RFcable line 102 preferably uses adjustable-length, to guarantee the design of antenna body winding displacement
Rational deployment；More preferably, RFcable line is connect using 1mm diameter double end bonding wire with antenna body 101, in this way can be further
Guarantee signal transmitting and received performance；The metal shell interior surface of intelligent door lock is arranged in above-mentioned antenna modules.
Be illustrated in figure 2 the principle of the present invention figure: the π type match bit of net mate device 103 using after C1 ground connection with capacitor
Parallel connection and the series inductance L1 composition between the capacitor C1 and the capacitor C2 after C2 ground connection, use and set-up mode simultaneously of going here and there
Received signal is further ensured that within tunable range, guarantees the normal of antenna impedance, to improve the communicativeness of antenna
Energy.
The present embodiment also provides a kind of intelligent door lock, and it includes above-mentioned antenna modules, antenna modules are arranged in intelligent door
The metal object inner surface of lock.
Specific workflow of the invention is that, when antenna body 101 receives the signal of client's using terminal, can pass through
RFCable line 102 transmits signal message for net mate device 103, and net mate device 103, which passes through, carries out the signal received
The resonance frequency of the signal received is adjusted within the OK range in set π type match bit, if met by identification
Smart lock terminal is then amplified to reach unlocking and locking function by power amplifier 104, so that improving antenna receives signal
