Description

Technical Field

[0001] The utility model relates to the technical field of electronic intelligent locks, and particularly relates to an intelligent electronic control lock.

Background Art

[0002] In the traditional lock technology field, it can be divided into two types of locks. One is the traditional mechanical lock technology field. In this field, people control the lock through a physical key and achieve the opening and closing control of the lock through a series of mechanical movements. Although this kind of mechanical lock is widely used, with the progress of technology, it can no longer meet people's diverse daily needs, such as remote unlocking and keyless unlocking. Therefore, a new type of intelligent lock has emerged, which can achieve remote control and keyless unlocking. For example, in daily processing, users can remotely control through devices such as NFC and terminal device software.

[0003] However, through market research, it can be known that although intelligent locks are more convenient to use, without the close cooperation and pure mechanical control of mechanical locks, the cooperation stability of intelligent locks significantly decreases, and their volume is often relatively large.

Content of the Utility Model

[0004] In view of the above technical problems in the prior art, the utility model provides an intelligent electronic control lock, which is characterized in that it includes: a lock rod, which is a slender rod-shaped structure; a lock tongue, which cooperates with the lock rod to achieve separation or engagement; a driving component, which is connected to the lock rod and is used to receive an external signal to control the rotation of the lock rod; the lock rod drives the movement of the lock tongue by rotating; a housing, and the lock rod, the lock tongue and the driving component are all installed in the housing; wherein a part of the lock tongue is exposed outside the housing.

[0005] Specifically, the intelligent electronic control lock includes: a first pivot shaft, and the lock tongue rotates around the first pivot shaft to open and close the intelligent electronic control lock; a spring, which is arranged on one side of the lock tongue and provides a biasing pressure to the lock tongue, so that the lock tongue rotates around the first pivot shaft.

[0006] Specifically, the intelligent electronic control lock includes: a second pivot shaft, and the lock rod rotates around the second pivot shaft to achieve the separation or engagement between the lock rod and the lock tongue.

[0007] Specifically, the intelligent electronic control lock includes: a first torsion spring; the first torsion spring is wound around the first pivot shaft and provides a torsional force to the lock tongue.

[0008] Specifically, the intelligent electronic control lock includes a second torsion spring; the second torsion spring is wound around the second pivot shaft and provides a torsional force to the lock rod.

[0009] Specifically, the lock rod includes a lock hook which is provided with a concave area through shape change, and the lock tongue is engaged with the concave area; a connecting rod, wherein the lock hook and the connecting rod are respectively arranged at two ends of the second pivot shaft, and the connecting rod is connected to the driving component.

[0010] Specifically, the lock tongue includes: a lock tongue body; a lock tongue claw which is integrally designed with the lock tongue body; the lock tongue claw and the lock tongue body enclose a notch for accommodating a retainer.

[0011] Specifically, the driving component includes: a valve; an actuator externally connected to the output shaft of the valve; the actuator is connected to the connecting rod; a driving housing, and the valve and the actuator are installed in the driving housing.

[0012] Optionally, the valve can also be a solenoid valve or an electric valve. As long as it can generate a station change under the action of electric drive. For example, when the solenoid valve is energized under the action of electricity, an electromagnetic force is generated by the electromagnetic coil to lift the closing member from the valve seat, and the valve opens; when the power is cut off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, and the valve closes; thereby driving the actuator to move. The electric valve is essentially a motor device, and through an external power supply, the battery device realizes forward and reverse rotation to drive the actuator to move.

[0013] Specifically, the intelligent electronic control lock further includes a detection switch installed on the side of the driving housing, and the detection switch is used to identify the opening and closing of the intelligent electronic control lock.

[0025] Please refer to Figure 1 、 Figure 2 、Figure 3 Please refer to Figure 1 , the overall shape of the intelligent electric control lock 10 is a square housing 11, and the housing 11 includes an upper housing 111 and a lower housing 113, and the upper housing 111 and the lower housing 113 are fixedly connected to each other.

[0026] It should be noted that the fixed connection can be a screw connection, or a connection method such as snap fit or adhesive bonding, etc., which will not be listed one by one here.

[0027] At the same time, the fixed connection can be a detachable connection or a non-detachable connection.

[0028] Please refer to Figure 2 and Figure 3 , the intelligent electric control lock 10 includes a locking tongue 13, a locking rod 15, a driving member 17, a spring 19, a first pivot shaft 12, a second pivot shaft 14, a first torsion spring 16, and a second torsion spring 18.

[0029] Among them, the first pivot shaft 12 and the second pivot shaft 14 can be arranged to be connected to the upper housing 111 or the lower housing 113.

[0030] Among them, the driving member 17 can drive the locking rod 15 to rotate around the second pivot shaft 14, and then drive the locking tongue 13 to rotate around the first pivot shaft 12. The first torsion spring 16 and the second torsion spring 18 are respectively wound around the first pivot shaft 12 and the second pivot shaft 14. The first torsion spring 16 and the second torsion spring 18 provide a biasing force to the locking tongue 13 and the locking rod 15 by being wound around the first pivot shaft 12 and the second pivot shaft 14.

[0031] In addition, the spring 19 is arranged on one side of the locking tongue 13 to provide a biasing pressure to the locking tongue 13, so that the locking tongue 13 rotates around the first pivot shaft 12.

[0032] It should be noted that under the dual action of the spring 19 and the first torsion spring 16, when the locking tongue 13 and the locking rod 15 are in a engaged state, the connection between the two is more firm and not easily detached.

[0033] The locking tongue 13 includes a locking tongue body 131 and a locking tongue claw 133. The locking tongue body 131 and the locking tongue claw 133 are integrally designed. The locking tongue body 131 and the locking tongue claw 133 enclose a notch 135, and the notch is used to accommodate the retainer 20. When the retainer 20 enters the notch 135, the intelligent electric control lock 10 is in a closed state; when the retainer 20 exits the notch 135, the intelligent electric control lock 10 is in an open state.

[0034] It should be noted that the retainer 20 is an environmental technical feature. In order to exert the technical function of the intelligent electronic control lock 10, it is necessary to lock external objects. The retainer 20 can be externally connected to items such as door panels, drawers, and takeaway cabinets to achieve locking between two components.

[0035] The lock rod 15 includes a lock hook 151 and the connecting rod 153. The lock hook 151 and the connecting rod 153 are integrally designed. The lock hook 151 and the connecting rod 153 are respectively arranged at both ends of the second pivot shaft 14, that is, the lock hook 151, the second pivot shaft 14, and the connecting rod 153 are arranged in sequence, and the lock hook 151 and the connecting rod 153 can rotate around the second pivot shaft 14.

[0036] Optionally, the end of the connecting rod 153 extends out of the housing 11, and the user can also control the opening and closing of the intelligent electronic control lock 10 by manually operating the end of the connecting rod 153.

[0037] The driving component 17 includes a valve 171, an actuator 173, and a driving housing 175. The valve 171 can be externally connected to a power source. The valve 171 includes an output shaft, and the output shaft can be externally connected to the actuator 173. The actuator 173 can move longitudinally under the action of the valve, that is, convert the rotational force of the output shaft of the valve 171 into a longitudinal force. The actuator 173 is connected to the connecting rod 153. When the actuator 173 moves longitudinally under the action of the valve 171, it can drive the connecting rod 153 to rotate. The valve is installed inside the driving housing 175, and the driving housing 175 can be split into upper and lower parts. According to actual usage requirements, sealing treatment can be carried out between the upper and lower parts to achieve the purpose of waterproofing.

[0038] Optionally, the power source externally connected to the valve 171 can be a battery or a current after transformation from mains power.

[0039] In addition, the intelligent electronic control lock 10 further includes a detection switch 177, which is installed on the side of the driving housing 175. The detection switch 177 is used to identify the opening and closing of the intelligent electronic control lock 10. The detection switch 177 determines the opening and closing of the intelligent electronic control lock 10 by identifying the position change of the lock tongue 13 or the lock rod 15.

[0040] The unlocking action and the locking action are described below in conjunction with the working principle of the intelligent electronic control lock 10.

[0041] In this exemplary embodiment, the valve 171 is a solenoid valve, and the actuator 173 is a movable iron core.

[0042] Unlocking state: As Figure 2 and Figure 3 shown, when the intelligent electric control lock 10 needs to be unlocked, an external power supply is connected to the solenoid valve 171, and a power failure occurs during the process of supplying power to the solenoid valve 171 through the external power supply. Since the solenoid valve 171 no longer drives the movable iron core 173, the movable iron core 173 is released, causing the movable iron core 173 to move outwards. The movable iron core 173 is connected to the connecting rod 153, and the connecting rod 153 is also lifted upwards. At this time, the locking lever 15 rotates about the second pivot shaft 14, and the second torsion spring 18 provides resistance to the locking lever 15 (always causing the locking lever to rotate clockwise), while the movable iron core 173 provides power to the locking lever 15. The locking lever 15 forms a labor-saving lever, enabling the movable iron core 173 to easily rotate the locking lever 15 counterclockwise.

[0043] In addition, the end of the connecting rod 153 extends out of the housing, and its end can facilitate manual operation by the user. When the intelligent electric control lock 10 malfunctions, manual operation can be performed through the end of the connecting rod 153. Moreover, a rope or cable can be externally connected to the end of the connecting rod 153 to facilitate more labor-saving operation.

[0044] When the locking lever 15 rotates counterclockwise, at this time, the locking lever 15 and the locking tongue 13 are not in contact. Under the dual action of the spring 19 and the first torsion spring 16, the locking tongue 13 is in an open state. At this time, the notch 135 formed by the locking tongue claw 133 and the locking tongue body 131 faces outwards, and a vacant area also appears in the housing 11 at this position, facilitating the retainer 20 to enter the notch 135.

[0045] At this time, the intelligent electric control lock 10 is in an open state. The detection switch 177 detects its open state and then shuts off the power supply.

[0046] Locked state: Under the action of an external force, the retainer 20 enters the notch 135. Under the action of the external force, the double action of the spring 19 and the first torsion spring 16 is overcome, causing the locking tongue 13 to rotate. Further, the locking tongue claw 133 is engaged with the locking hook 151. The locking hook is provided with a recessed area through a shape change, and the locking tongue claw 133 is engaged in the recessed area. At this time, the locking tongue claw 133 pushes up the locking hook 151. The locking hook 151 and the connecting rod 153 are respectively disposed at both ends of the second pivot shaft 14. When the locking hook 151 is pushed up, the connecting rod 153 descends, pressing down the movable iron core 173. The locking rod 15 rotates clockwise at this time. At this time, under the action of the locking tongue claw 133 and the locking tongue body 131, the retainer 20 is held in the notch 135 area, and the locking operation is completed.

[0047] When changing from the locked state to the unlocked state, the detection switch 177 is turned on, causing the external power supply to energize the solenoid valve 171, causing the movable iron core 173 to complete a contraction movement. The movable iron core 173 pulls the locking rod 15 to move clockwise, causing the locking hook 151 to lift. The locking hook 151 and the locking tongue claw 133 are disengaged. Under the double action of the spring 19 and the first torsion spring 16, the locking tongue claw 133 releases the retainer 20.

[0048] For the intelligent electronic control lock 10 provided by the present invention, the layout of the locking rod 15, the locking tongue 13, and the driving component 17 is compact, making its overall volume small. Under the action of the spring 19 and the first torsion spring 16, the locking tongue 13 is relatively firm and stable under the external force of the two springs in both the locked state and the unlocked state, and it is not easy to have an accident of detachment.

[0049] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
