[0040] The embodiments of the present utility model will be further described below in conjunction with the drawings.

[0041] According to some embodiments of the present utility model, referring to Figures 1 to 4, The fingerprint lock includes a first housing 100, a circuit board 200, and a fingerprint sensing module 230. An installation hole 110, a first through hole 111, and a second through hole 112 are provided on the upper end surface of the first housing 100. The circuit board 200 is disposed inside the first housing 100. A first conductive column 210 is connected to the positive power terminal of the circuit board 200, and a second conductive column 220 is connected to the negative power terminal of the circuit board 200. The upper end of the first conductive column 210 is inserted into the first through hole 111, and the upper end of the second conductive column 220 is inserted into the second through hole 112. The fingerprint sensing module 230 is located at the installation hole 110. The fingerprint sensing module 230 is installed on the circuit board 200 and electrically connected to the circuit board 200.

[0042] When the fingerprint lock is installed on a cabinet or a door, the fingerprint sensing module 230 is located outside for the operator to use fingerprints to unlock the lock. When the circuit board 200 runs out of power, the operator on the outside can connect the positive and negative poles of the power supply to the first conductive column 210 and the second conductive column 220 respectively, so as to temporarily supply power to the circuit board 200, and then the fingerprint lock can resume normal operation, facilitating the opening of the fingerprint lock. This avoids the need for violent disassembly of the fingerprint lock.

[0043] This fingerprint lock can handle sudden power outages. With only an external power source such as a power bank or a power supply plug, by abutting the positive and negative poles of the external power source against the first conductive column 210 and the second conductive column 220 respectively, the circuit board 200 of the fingerprint lock can be powered to ensure the normal operation of the fingerprint lock.

[0044] According to some embodiments of the present invention, refer to Figures 2 to 5 , The first housing 100 includes a housing body 300 and a housing cover 400. The housing cover 400 is located at the upper end of the housing body 300, and the housing body 300 and the housing cover 400 are fixedly connected. When the housing cover 400 is closed on the housing body 300, the housing body 300 and the housing cover 400 jointly clamp the circuit board 200, that is, there is no need to fix the circuit board 200 with screws, which is convenient for assembly.

[0045] Preferably, refer to Figures 2 to 5 , A plurality of support columns 310 are provided on the upper end surface of the housing body 300. The plurality of support columns 310 jointly support the circuit board 200. When the housing body 300 is connected to the housing cover 400, the upper ends of the support columns 310 and the lower end surface of the housing cover 400 jointly clamp the circuit board 200, so that the circuit board 200 is relatively fixed to the first housing 100.

[0046] According to some embodiments of the present invention, refer to Figures 2 to 5, the lower end surface of the shell cover 400 extends downward to form an annular portion 410. The annular portion 410 is annular, and the inner peripheral wall of the annular portion 410 is provided with a rib 420 extending in the up and down direction. The upper end surface of the shell body 300 is provided with a connecting column 320, and the side wall of the connecting column 320 is provided with a notch 321 extending in the up and down direction. The rib 420 is inserted into the notch 321 and is in interference fit with the notch 321, so that the shell cover 400 and the shell body 300 are relatively fixed, and this assembly method is simple and fast.

[0047] According to some embodiments of the present invention, refer to Figures 2 to 5 , the upper end surface of the shell body 300 is provided with a wire passing hole 330, and the wires of the circuit board 200 can pass through the wire passing hole 330 to facilitate wire routing. The shell body 300 is provided with a threaded hole 340 extending in the up and down direction, and the threaded hole 340 is used to connect with the lock body. It can be understood that the fingerprint lock is installed on the lock body, and there is a battery on the lock body to provide power. The wires of the circuit board 200 pass through the wire passing hole 330 and then connect with the battery of the lock body. When the battery runs out of power or there is a power outage indoors and the lock body cannot be powered, the positive and negative electrodes of an external portable power supply can be respectively connected to the first conductive column 210 and the second conductive column 220, so as to supply power to the circuit board 200, and then the fingerprint lock can resume normal operation, so as to facilitate opening the fingerprint lock and then entering the room to replace the power supply of the lock body.

[0048] According to some embodiments of the present invention, refer to Figure 2 , the upper end surface of the first shell 100 is provided with a third through hole 113. The circuit board 200 is connected with an indicator light, and the indicator light is arranged in the third through hole 113. The indicator light is always on to indicate that the circuit board 200 has power, and when the indicator light goes out, it means that the circuit board 200 has no power.

[0049] According to some embodiments of the present invention, refer to Figure 2 , the upper end surface of the shell cover 400 is provided with an annular inclined surface 430. The annular inclined surface 430 inclines downward towards the direction close to the axis of the shell cover 400. The inner side of the annular inclined surface 430 forms an installation hole 110. The annular inclined surface 430 can improve the touch feeling between the thumb and the fingerprint sensing module 230 and facilitate the fingerprint sensing module 230 to identify fingerprints.

[0050] According to some embodiments of the present invention, refer to Figure 2 and Figure 6, the electronic lock assembly includes a fingerprint lock and a power supply line 500. The power supply line 500 includes a second housing 510, a power supply module, a first power supply post 521, and a second power supply post 522. The power supply module is installed inside the second housing 510. The first power supply post 521 is connected to the positive terminal of the power supply module, and the second power supply post 522 is connected to the negative terminal of the power supply module. When the first conductive post 210 abuts against the first power supply post 521 and the second conductive post 220 abuts against the second power supply post 522, one end of the power supply line 500 is connected to the circuit board 200 to temporarily supply power to the circuit board 200. The other end of the power supply line 500 is a USB socket, which can be connected to a power socket or a power bank, etc.

[0051] The electronic lock assembly uses this fingerprint lock. The fingerprint lock is installed on the door and located outdoors. When the circuit board 200 runs out of power, the first conductive post 210 abuts against the first power supply post 521, and the second conductive post 220 abuts against the second power supply post 522, so that the power supply line 500 temporarily supplies power to the circuit board 200 of the fingerprint lock, thereby enabling temporary power supply to the circuit board 200 from the outside, enabling the fingerprint lock to resume normal operation, and avoiding the need to violently disassemble the fingerprint lock.

[0052] According to some embodiments of the present invention, both the first power supply post 521 and the second power supply post 522 pass through and are slidably connected to the second housing 510. The lower ends of the first power supply post 521 and the second power supply post 522 both extend outside the second housing 510. A return spring is provided inside the second housing 510, and the return spring applies a downward force to the first power supply post 521 and the second power supply post 522. It can be understood that when the first conductive post 210 abuts against the first power supply post 521 and the second conductive post 220 abuts against the second power supply post 522, the return spring is compressed, that is, the return spring applies a reaction force to the first power supply post 521 and the second power supply post 522 to ensure that the first conductive post 210 tightly abuts against the first power supply post 521 and the second conductive post 220 tightly abuts against the second power supply post 522.

[0053] According to some embodiments of the present invention, a first N - pole magnet 241 and a first S - pole magnet 242 are provided on the circuit board 200. The first N - pole magnet 241 is located on the side of the first conductive post 210 away from the second conductive post 220, and the first S - pole magnet 242 is located on the side of the second conductive post 220 away from the first conductive post 210; a second N - pole magnet 531 and a second S - pole magnet 532 are provided on the second housing 510. The second N - pole magnet 531 is located on the side of the second power supply post 522 away from the first power supply post 521, and the second S - pole magnet 532 is located on the side of the first power supply post 521 away from the second power supply post 522; when the first conductive post 210 abuts against the first power supply post 521 and the second conductive post 220 abuts against the second power supply post 522, the first N - pole magnet 241 and the second S - pole magnet 532 are magnetically attracted and fitted, and the first S - pole magnet 242 and the second N - pole magnet 531 are magnetically attracted and fitted.

[0054] It can be understood that when the first power supply column 521 approaches the second conductive column 220 and the second power supply column 522 approaches the first conductive column 210, the first N-pole magnet 241 and the second N-pole magnet 531 repel each other with the same polarity, and the first S-pole magnet 242 and the second S-pole magnet 532 repel each other with the same polarity, preventing the positive and negative poles from being connected reversely. When the first power supply column 521 approaches the first conductive column 210 and the second power supply column 522 approaches the second conductive column 220, the first N-pole magnet 241 and the second S-pole magnet 532 attract each other with opposite polarities, and the second N-pole magnet 531 and the first S-pole magnet 242 attract each other with opposite polarities, thereby ensuring that the first conductive column 210 is in close contact with the first power supply column 521, and the second conductive column 220 is in close contact with the second power supply column 522.

[0055] Preferably, the first conductive column 210, the second conductive column 220, the first power supply column 521, and the second power supply column 522 are all copper columns. The first conductive column 210 and the second conductive column 220 are both firmly connected to the circuit board 200, replacing the traditional tin spraying process for solder pads on the circuit board 200. The solder pads are prone to oxidation, resulting in poor contact. The stability and conductivity of the first conductive column 210 and the second conductive column 220 are stronger.

[0057] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
