If the match fails, the processor will not work; the motor drive circuit is used to directly drive the motor 3 to rotate, and the motor 3 is powered on to control the direction of the motor 3, such as the H-bridge drive circuit. The processor forms different current loops by turning on different MOS tubes in the H-bridge control circuit to control the different directions of the motor 3. The control circuit board 2 is provided with an identity recognition module 20 for starting the electronic lock. The identity recognition module 20 is any one or more of a fingerprint recognition module, a voice recognition module, a face recognition module and a digital password module. The user's identity information is confirmed by identity recognition. If the match is made, the lock is unlocked, otherwise it is not unlocked. The fingerprint recognition module is preferably used. The fingerprint recognition module is a fingerprint sensor for collecting fingerprint images, including but not limited to a capacitive fingerprint sensor, an ultrasonic fingerprint sensor or an optical fingerprint sensor. The inner shell 1 is provided with a lock tongue 5 driven by a motor 3, and the lock tongue 5 is locked or unlocked by the driving movement of the motor 3. The inner shell 1 is also provided with a first mounting mechanism for movably mounting a lock beam 7 and a second mounting mechanism for movably mounting a lock shell. The first mounting mechanism is used to mount the lock beam 7, and the second mounting mechanism is used to mount the lock core in the lock shell. For example, if the first mounting mechanism is arranged on the right side of the inner shell 1, the lock tongue 5 is mounted on the top of the inner shell 1, and is driven by the motor 3 to move left and right at the top. The lock beam 7 is a U-shaped lock beam, one end of which is mounted on the inner shell 1 by the first mounting mechanism, and the other end is turned to the left end and pressed down to lock with the extended lock tongue 5.

[0025] As a further improvement, the control circuit board 2 is also provided with a wireless communication module (not shown in the figure), which can be used to connect to a smart terminal and then lock or unlock the smart terminal.

For example, the groove 10 is arranged on the right side of the inner housing 1 and is a groove in a vertical direction. In this way, after the lock beam 7 is inserted into the groove 10, the lock beam 7 is limited in the groove 10 and moves up and down by using a pin 101 inserted from the limiting through hole 100. At the same time, a telescopic spring is arranged between the lock beam 7 and the groove bottom of the groove 10 so that the lock beam installed in the first installation mechanism has a rebound force after being unlocked.

[0027] Further improvements, Figures 1 to 4 , Figure 6The locking cam 510 is a plurality of locking cams 512 that are provided on the upper portion of the inner shell 1.

The plurality of locking cams 512 are a plurality of locking cams 512 that are provided on the lower portion of the inner shell 1. The plurality of locking cams 512 are a plurality of locking cams 512 that are provided on the lower portion of the inner shell 1. When the locking end 510 is locked, the locking beam 7 is pressed on the surface of the inclined structure of the first locking end 510 and will not touch the groove wall of the first sliding groove 11. The locking beam 7 continues to press down, and the locking tongue 5 moves toward the force-bearing end 511. After the locking beam 7 is inserted into the groove at the bottom of the groove, the locking tongue 5 rebounds under the elastic force of the first telescopic spring 52, and the first locking end 510 is engaged with the locking groove on the locking beam 7, thereby realizing the locking of the locking beam 7 and the locking tongue 5.

If the motor 3 is an eccentric shaft motor, the vertical portion 50 passes through the through hole 110 at the bottom of the slot and abuts against the eccentric shaft 30 of the motor 3, so that the lock tongue 5 moves and locks or unlocks with the lock beam 7 through the rotation of the eccentric shaft 30 of the motor 3. At this time, a top plate can also be set on the top of the two baffles, and the top plate only covers one side of the force-bearing end 511 to prevent the first telescopic spring 52 from falling off, and the top surface of the first locking end 510 is exposed. When the lock core is installed in the lock shell, the lock shell extends an extension arm corresponding to the top surface of the first locking end 510. When the lock beam 7 is pulled out in the locked state, the extension arm presses against the top surface of the first locking end 510, thereby improving the firmness of the structure and the safety of the product.

The inside of the outer shell 6 is the accommodating space for accommodating the electronic lock core, and the electronic lock core of the integrated structure is snap-fitted and installed in the accommodating space; the lock tongue 5 is driven by the motor 3 to extend into the second lock hole 61 through the hole wall through hole 610 to lock or unlock the lock beam 7; at this time, when the identity recognition module 20 is a fingerprint recognition module, the fingerprint recognition module protrudes from the control circuit board 2, and a shell through hole 64 corresponding to the position of the fingerprint recognition module is arranged on the outer shell 6, and the fingerprint recognition module is exposed through the shell through hole 64, which is convenient for finger pressing during use; when the identity recognition module 20 is a voice recognition module or a face recognition module (camera), a window is correspondingly set on the outer shell to receive sound or expose the camera. At the same time, a third mounting mechanism for matching with the second mounting mechanism on the electronic lock core is also provided on the outer shell 6, and the outer shell 6 and the electronic lock core are assembled together through them. For example, vertical sliders 13 are provided on the outer side walls on opposite sides of the inner shell 1, and then a slider protrusion 130 is provided on the slider 13. The third mounting structure is a second slide groove 62 provided on the inner wall of the outer shell 6 for matching the slide of the slider 13, and a card groove 620 is provided in the groove bottom of the second slide groove 62. After the inner shell 1 is completely installed in the outer shell 6, the slider protrusion 130 is engaged in the card groove 620 to limit the electronic lock core in the outer shell 6; when the inner shell 1 and the outer shell 6 are threadedly connected, a through hole is provided at a position of the outer shell 6 corresponding to the threaded hole 14 on the inner shell 1, and then a screw is passed through the through hole and threadedly connected to the threaded hole, thereby connecting the two.

[0030] An electronic lock, such as Figures 1 to 7As shown in, the electronic lock core as described in any of the above items and the lock shell as described above are used, and also include a lock beam 7, one end of the lock beam 7 is a limit end 70 that passes through the first lock hole 60 and the first installation mechanism and can be detachably connected and can move up and down relative to the fingerprint lock core, and the other end is a second locking end 71 that can be inserted into the second lock hole 61 and locked with the fingerprint lock core; the lock beam 7 is a U-shaped structure, and when the first installation mechanism is a groove 10 arranged on the inner shell 1, and a limit through hole 100 is arranged on the groove wall of the groove 10, the outer wall of the limit end 70 of the lock beam 7 is concave The notch 700 is used to limit the movement of the limiting end 70. The limiting end 70 is provided with a second telescopic spring 102 between the lower part of the notch 700 and the bottom of the groove 10. The pin 101 is inserted into the notch 700 through the limiting through hole 100 to limit the up and down movement of the lock beam 7. The second locking end 71 is provided with a locking groove locked with the lock tongue 5, that is, the groove 10 is in the vertical direction, the limiting end 70 is matched and inserted into the groove 10 and is separated from the bottom of the groove 10 by a distance, and the notch 700 extends along the axial direction of the limiting end 70. After the notch 700 is set on the end 70, a space is formed between the inner wall of the groove 10 and the limiting end 70 at the position corresponding to the notch 700, and the limiting through hole 100 is set on the inner wall of the groove 10 corresponding to the space, and then the pin 101 is inserted into the space through the limiting through hole 100 to limit the upward and downward movement of the lock beam 7. In this way, when the limiting end 70 is pulled upward, the pin 101 presses against the lower end of the space to prevent the lock beam 7 from being pulled out, and when the limiting end 70 is pressed downward, the pin 101 presses against the upper end of the space to prevent the lock beam 7 from being pressed down too much , and the second telescopic spring 102 is compressed when the lock beam 7 is pressed down to lock, and after unlocking, the lock beam 7 can be bounced upward by the elastic force of the second telescopic spring 102; during installation, a part of the inner housing 1 is first inserted into the outer housing 6, and the limiting through hole 100 is exposed outside the outer housing 6, and then the lock beam 7 is inserted from the first lock hole 60 into the groove 10 of the inner housing 1 pre-installed with the second telescopic spring 102, and then the limiting end 70 of the lock beam 7 is limited in the groove 10 by the pin 101, and then the inner housing 1 is pushed into the outer housing 6. The outer housing 6 will prevent the pin 101 from falling off, and the installation structure is simple and practical. The pin 101 is used to limit the up and down movement of the lock beam 7, and the pin 101 is also used to limit the lock beam 7 on the electronic lock core to realize the detachable connection between the lock beam 7 and the electronic lock core. The assembly of the entire electronic lock is simple and convenient. It is no longer necessary to consider how to arrange the various components constituting the electronic lock core in the outer shell 6. Only a simple accommodating space for installing the electronic lock core is required, which reduces the production cost. When disassembly is required, when the lock beam 7 and the lock tongue 5 are not locked, the electronic lock core is pushed downward by the lock beam 7, and the slider protrusion 130 is disengaged from the engagement with the card slot 620, thereby pushing the electronic lock core out of the outer shell 6.

[0031] Further improvements, such as Figure 1 , Figure 2 and Figure 5 As shown in the figure, an extended protrusion 63 extends from the inner top wall of the outer shell 6 and abuts against the top of the lock tongue 5. In this way, in the locked state, when the lock beam 7 is pulled upward, the lock tongue 5 will be subjected to an upward thrust, which will have a certain impact on its installation structure. The extended protrusion 63 applies a reverse force to the lock tongue 5, and the upward thrust is balanced, thereby enhancing the strength of the installation structure of the lock tongue 5.

[0032] Although the utility model has been described in detail above with general descriptions and specific implementation schemes, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
