[0020] The present invention provides an electric control lock. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] See also Figure 1-8 The present invention provides an electric lock. The accompanying drawings are intended only to illustrate the structural principles and are not to scale with the actual product. The drawings only depict structures relevant to the invention of this application; some conventional structures are not specifically depicted. To facilitate viewing of the internal structure of the electric lock, only the lower housing is shown; the upper housing is not.

[0022] The terms "first" and "second" described herein are merely different names for similar structures for the convenience of explanation and are not intended to limit this application.

[0023] An electric lock includes a housing 91, in which a main board 92 (or a "PCB board" or other name), a motor 31, a locking plate 51 and a lock hook plate 52 are arranged. The lock hook plate and the locking plate are rotatably connected to the housing respectively. The main shaft of the motor is provided with a worm 22, and the worm is connected to a worm wheel 23; a push rod 42 and a partition 98 are also provided in the housing. The push rod passes through the partition and is connected to a push block 41. A rack 411 is provided on the push block; a gear set is provided between the rack and the worm wheel; the locking plate is provided with a connecting portion 511 and an abutting portion 512. The connecting portion 511 of the locking plate is connected to the push rod 42; the abutting portion of the locking plate is provided with a first abutting surface 410 (such as Figure 4 As shown in FIG), the lock hook plate is provided with a second abutting surface 520 (as shown in FIG. Figure 5 shown).

[0024] In actual applications, the above-mentioned mainboard is provided with structures such as a controller, a Bluetooth module, and an NFC module (not shown in the figure), but these structures are not the invention points of this application, and therefore, they are no longer described and limited in detail in this article.

[0025] As can be seen from the accompanying drawings, the gear set includes a first gear 31, a second gear 32, a third gear 33, a fourth gear 34, and a fifth gear 35. The first gear and the worm gear are coaxially arranged, and the fifth gear 35 meshes with the rack 411. Because the first intermediate gear and the worm gear are coaxially arranged, the rotation of the worm gear drives the first gear, which in turn drives the rotation of each gear, thereby driving the linear movement of the push block and the push rod. It should be noted that although the accompanying drawings show five gears, in actual applications, the number and arrangement of gears in the gear set can be determined based on actual conditions.

[0026] Furthermore, the connection between the push rod and the push block can be configured as follows: one end of the push rod 42 is provided with a flange 422 and a boss 421, and the push block is provided with a socket 410, into which the boss is inserted, with the boss and socket having matching shapes (the boss is preferably a circular boss, and the socket is preferably a circular socket). This configuration achieves a detachable connection between the push rod and the push block, making assembly very simple.

[0027] Preferably, the push rod is a round rod, a first spring 491 is sleeved on the push rod, and the push block is provided with a second spring 492. One end of the first spring abuts against the partition, and the other end abuts against the flange.

[0028] Preferably, the above-mentioned insertion hole is a through hole, one end of the second spring is inserted into the insertion hole, and the other end of the second spring is against the side plate 911 of the shell.

[0029] It can also be observed from the accompanying drawings that the ejector rod is provided with a notch 420, and during assembly, the connecting plate of the locking plate is simply inserted into the notch. This arrangement makes the connection between the ejector rod and the locking plate very simple.

[0030] Furthermore, the lock hook plate is provided with a first lock hook 521 and a second lock hook 522. Correspondingly, a lock hole 900 is provided on the housing. Figure 8 As shown, in actual application, the above electric lock is also provided with a corresponding lock catch 100 (or similar structure). During installation, the electric lock is set on the door panel and the lock catch is set on the cabinet or door frame; or the opposite arrangement is: the lock catch is set on the door panel and the electric lock is set on the cabinet or door frame. For ease of understanding, Figure 9 Draw the front view of the lock.

[0031] Furthermore, a latch 81 is installed on the partition, and a microswitch 82 is installed in the housing at a position corresponding to the end of the latch. The first lock hook can abut against one end of the latch. The significance of the microswitch is that when the electric lock is locked, the microswitch is triggered, sending an electrical signal to the mainboard, which further controls the motor to rotate and lock the lock hook plate. In other words, the microswitch eliminates the need to manually control the motor to lock the lock hook plate after the lock is engaged.

[0032] Furthermore, a third spring 83 is provided at the other end of the latch, and a baffle 84 is provided on the housing, with one end of the third spring abutting against the baffle.

[0033] For ease of understanding, the working principle of the electric lock is further explained below: (1) When the electric lock is in the unlocked state (for example, the door panel is in the open state), the second lock hook does not block the lock hole; (2) The lock catch enters the lock hole (for example, the door panel is closed), and the lock catch pushes the first lock hook to rotate and abut against the latch until the micro switch is triggered; (3) The motor rotates, the worm drives the worm gear to rotate, and the driven gear is driven to rotate through each intermediate gear, further driving the push block and the push rod to move linearly, and the push rod drives the locking plate to rotate clockwise, the first abutting surface and the second abutting surface abut together, and the second lock hook blocks the lock hole, thereby locking the lock hook plate (for example, Figure 8 (4) When unlocking, the motor reverses, the locking plate rotates counterclockwise, the lock hook plate rotates clockwise, the second lock hook no longer blocks the lock hole, and the lock catch can be withdrawn from the lock hole (for example: opening the door panel).

[0034] The above unlocking can be achieved through Bluetooth, NFC, password, etc. Since these unlocking methods themselves are not the invention point of this application, they are not specifically limited in this article.

[0035] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
