DETAILED DESCRIPTION

[0029] Example:

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified or limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a signal connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific circumstances. The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0031] See Figure 1-5 As shown, the electronic lock provided in this embodiment includes a front shell 1, a bottom shell 2, a lock core structure 3 and a circuit control panel 4; wherein, as shown in FIG. Figure 5 As shown, a circuit control panel clip 11 is provided in the bottom surface of the face shell 1 for clamping the circuit control panel 4 in the bottom surface of the face shell 1; specifically, in this embodiment, three circuit control panel clips 11 are provided, which are respectively used to clamp on the two opposite sides of the circuit control panel 4, that is, one is provided on one side and two are provided on the other side, and the whole is distributed in a triangle, so as to facilitate the assembly and placement of the circuit control panel 4; a lock core structure clip 12 is also provided in the bottom surface of the face shell 1 for clamping the lock core structure 3 in the bottom surface of the face shell 1. Similarly, three lock core structure clips 12 are also provided, and the whole is distributed in a triangle, so as to facilitate the assembly and installation of the lock core structure 3; the bottom shell 2 and the face shell 1 are installed in coordination to secure the lock core structure 3 and the circuit control panel 4 in the space formed by the bottom shell and the face shell.

[0032] Since the circuit control panel snap 11 and the lock core structure snap 12 are respectively provided on the bottom surface of the face shell 1, the circuit control panel 4 and the lock core structure 3 can be quickly assembled. The whole process is simple and fast. The assembly and fixation are performed by snapping and pressing. Compared with the traditional method of fixing with screws, the snapping and pressing assembly method is simpler and has lower manufacturing cost.

[0033] As a preference of this embodiment, the above-mentioned electronic lock also includes a touch panel 5, a fingerprint decorative plate 6 and a fingerprint module 7; the touch panel 5 is provided with a panel fingerprint decorative plate mounting hole, and the face shell is provided with a face shell fingerprint decorative plate mounting hole, and the face shell fingerprint decorative plate mounting hole and the panel fingerprint mounting hole are arranged opposite to each other; the fingerprint module 7 is arranged on the surface of the circuit control panel 4, and a card slot 41 is provided in the circuit control panel 4 and on opposite sides of the fingerprint module 7, and the distance between the two card slots 41 does not exceed the opening range of the panel fingerprint decorative plate mounting hole and the face shell fingerprint decorative plate mounting hole; a fingerprint module mounting hole is provided in the middle of the fingerprint decorative plate, and a fingerprint decorative plate buckle 61 matching the card slot 41 is provided on the bottom surface of the fingerprint decorative plate 6. In this way, when assembling the touch panel 5, the front shell 1, the circuit control panel 4, and the fingerprint decorative plate 6, it is only necessary to place the touch panel 5 on the upper surface of the front shell 1, assemble the circuit control panel 4 in the circuit control panel clip 11 on the bottom surface of the front shell, and align the mounting holes. Then, assemble the fingerprint decorative plate. Since the bottom surface of the fingerprint decorative plate 6 is provided with two fingerprint decorative plate clips 61, when an external force is applied to the surface of the fingerprint decorative plate 6, the fingerprint decorative plate clips 61 will move along the mounting holes of the touch panel 5 and the front shell 1. When the guide slope of the fingerprint decorative plate clip 61 hits the slot 41 of the circuit control panel 4, the barb portion of the fingerprint decorative plate clip 61 will tightly hook the circuit control panel 4, thereby achieving the fingerprint decorative plate and circuit control panel being firmly fixed to the front shell. The whole process is simple and quick. By using a clip structure for assembly and fixing, compared with the traditional method of fixing with screws, the clip installation is simpler and has a lower manufacturing cost. When all parts are assembled, the bottom shell 2 can be installed. The bottom shell 2 is fixed to the front shell with screws, which can well protect the core components.

[0034] Specifically, the fingerprint decorative plate 6 is made of a plastic material. When the guide slope of the fingerprint decorative plate buckle 61 contacts the slot 41 of the circuit control panel 4, it causes the fingerprint decorative plate buckle 61 to undergo plastic deformation, bending backward. Once pressed into place, the deformed portion of the fingerprint decorative plate buckle 61 automatically rebounds, allowing the barbed portion of the fingerprint decorative plate buckle 61 to tightly hook onto the circuit control panel 4. The plastic deformation of the fingerprint decorative plate buckle 61 facilitates assembly and disassembly, further improving assembly efficiency. Similarly, the circuit control panel buckle 11 and the lock core structure buckle 12 are also made of plastic material and can undergo plastic deformation to facilitate assembly.

[0035] Specifically, the above-mentioned electronic lock further includes a knob 8. Figure 6-10 As shown, the above-mentioned lock core structure includes a rotating connector, an electromagnet 31, a locking rod 32 and a return spring 33; the rotating connector is connected and installed with the knob 8, and the rotating connector is driven to rotate by the knob 8, and a locking groove is provided in the rotating connector; the locking rod 32 is movably installed in the electromagnet 31, and a blocking shoulder 321 is provided on the surface of the locking rod 32, and a return spring 33 is provided on the locking rod part between the blocking shoulder 321 and the end face of the electromagnet 31, and the locking rod 32 is used to be inserted into the locking groove; the signal output end of the circuit control panel 4 is connected to the electromagnet 31 to control whether the electromagnet 31 is energized. Thus, when the lock is to be locked, the knob 8 is rotated, causing the rotating connector to rotate. When the locking slot is rotated to align with the locking rod 32, the locking rod 32 is inserted into the locking slot under the elastic force of the return spring 33, thereby limiting the rotational freedom of the rotating connector and achieving the purpose of locking. When the fingerprint password is entered correctly, the circuit control panel controls the electromagnet 31 to be energized. Under the magnetic attraction, the locking rod 32 is controlled to retract inward. The rotating connector, no longer restricted by the locking rod 32, can rotate 90 degrees in the unlocking direction, thus achieving the purpose of unlocking. Since the electromagnet does not consume power when locking, it only consumes power during the unlocking period. The electromagnet 31 is continuously energized for approximately 3 seconds. If the knob is not rotated within 3 seconds, the electromagnet is de-energized and the locking rod 32 is reinserted into the locking slot. In this way, the power consumption of the electromagnet 31 is very low.

[0036] It can be seen that the lock core structure provided in this embodiment is cleverly designed. The purpose of locking and unlocking can be achieved by driving the lock rod through the locking groove by the electromagnet. The entire structure is simple, the required parts are small, the precision requirements are not high, and the control is simple and the power consumption is low, which can greatly reduce the production difficulty and manufacturing cost.

[0037] As an improvement of the above lock core structure, the lock core structure further includes a shaft base 34, such as Figure 8As shown, a rotating connector mounting slot 341 and an electromagnet mounting slot 342 are provided in the rotating shaft base 34, that is, the entire rotating connector and the electromagnet 31 are installed in the same rotating shaft base 34, which makes the entire lock core structure more compact while facilitating assembly. In this way, the entire lock core structure is also an integrated design, which can be easily and quickly assembled. Specifically, the rotating shaft base 34 is made of metal and is fixed to the door panel from the inside with screws to prevent prying. A rotation limiter is provided on the surface of the rotary connector, and a corresponding through hole 3411 is provided on the wall of the rotary connector mounting slot 341 for allowing the rotation limiter to rotate. In other words, the rotation limiter can rotate within the range of the through hole 3411. Specifically, in this embodiment, the opening range of the through hole 3411 allows the knob 1 to rotate within a range of 0-90 degrees, that is, the knob in the unlocked state and the knob in the locked state are exactly 90 degrees. Rotating the knob 90 degrees in the locking direction can achieve locking, and conversely, rotating the knob 90 degrees in the unlocking direction can achieve unlocking. The electromagnet mounting slot 342 is provided with a lock rod mounting hole 3421. The aperture of the lock rod mounting hole 3421 is smaller than the diameter of the blocking shoulder 321. Thus, under the blocking action of the blocking shoulder 321, the lock rod 32 can be prevented from excessively moving toward the locking slot and preventing the lock rod 32 from detaching from the electromagnet 31. When the rotation limit part of the rotating connector rotates and touches the outer wall surface of the electromagnet mounting slot 342, the locking slot is opposite to the locking rod mounting hole 3421. In this way, when the rotating connector rotates to the end of the locking direction, it can be ensured that the locking slot is opposite to the locking rod mounting hole 3421, thereby achieving the purpose of locking.

[0038] In addition, in order to facilitate the fixing of the knob and the lock tongue, the above-mentioned rotary connector includes a knob connecting shaft 35 and a rotating shaft sleeve 36; Figure 10 As shown, the knob connecting shaft 35 is used to connect the knob 8, and the rotation limit portion 353 is provided on its surface; a shaft sleeve mounting hole 351 is provided in the knob connecting shaft 35, and the shaft sleeve 36 is correspondingly sleeved in the shaft sleeve mounting hole 351 for quick installation; a first through hole is provided through the bottom of the shaft sleeve mounting hole 351, and the first through hole facilitates the fixed installation of the knob 8, as shown in FIG. Figure 9 As shown, a second through-hole 361 corresponding to the first through-hole is provided through the shaft sleeve 36 to facilitate installation of the lock tongue. Correspondingly, a locking groove 362 is provided on the shaft sleeve 36. Specifically, the knob connecting shaft 35 is made of plastic, while the shaft sleeve 36 is made of metal. The metal shaft sleeve 36 is used to reinforce and connect to the lock tongue or other accessories.

[0039] As another preferred embodiment of the lock core structure, the lock core structure 3 further includes a limit spring 37; one end of the limit spring 37 is connected to and mounted on the knob connecting shaft 35, and the other end is sleeved onto a support on the bottom surface of the housing 1. Thus, under the action of the limit spring 37, when the knob 8 is rotated to the unlocked or locked state, the limit spring 37 can keep the knob 8 in a stationary state. Without the influence of external forces, the knob will not rotate, thereby effectively preventing the occurrence of accidental unlocking or locking.

[0040] As another preferred embodiment of the lock core structure, a position sensor 352 is provided on the surface of the rotation limiter 353. This sensor senses whether the lock rod 32 is inserted into the locking slot 362, thereby determining whether the lock core structure is in the unlocked or locked state. The position sensor 352 is connected to the circuit control panel 4. When the lock remains in the unlocked state for a preset time, a buzzer on the circuit control panel 4 will sound a lock prompt to remind the user to close the door and lock it. Specifically, in this embodiment, the position sensor 352 is a Hall effect magnet.

[0041] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the essence of the present invention are intended to be covered by the scope of protection of the present invention.
