[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0045] See also Figure 1 to Figure 2 The embodiment of the present application proposes a hidden lock, including a housing 100 , a locking mechanism 200 , an elastic member 300 , a lock hook 400 and a blocking piece 700 .

[0046] An accommodating cavity (not shown in the figure) is formed inside the housing 100, and an opening 140 communicating with the accommodating cavity is provided on the outer surface. The specific material of the housing 100 may be, but is not limited to, plastic or metal, and this application does not limit this. In some structural forms, the housing 100 includes a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 enclose a accommodating cavity. The specific connection method between the first shell 110 and the second shell 120 is not limited here. The first shell 110 may be, but is not limited to, connected to the second shell 120 by one or more of the methods such as screw connection or snap connection, and the designer may make a reasonable choice according to actual needs.

[0047] The locking mechanism 200 is installed in the accommodating cavity. Figure 2 The locking mechanism 200 includes a driving device 210 and a locking member 220, and the driving device 210 drives the locking member 220 to slide in the accommodating cavity. In some embodiments of the present application, the driving device 210 may include an electromagnetic coil 212 and a reset member (not shown in the figure). The electromagnetic coil 212 is sleeved on the outside of the locking member 220. Among them, the locking member 220 can be configured as an iron material or a magnetic material. In addition, the locking member 220 can be rod-shaped or block-shaped. The present application does not limit the specific material and specific structure of the locking member 220. The reset member can be a spring, a torsion spring, a tension spring, etc., and the present application does not limit this. One end of the reset member is connected to the locking member 220, and the other end is connected to the housing or the electromagnetic coil 212. In this way, the reset member generates a pulling force to move the locking member 220 outward. In some other embodiments, the driving device 210 can also be a motor, and the locking member 220 can be a telescopic rod. The power supply 510 drives the motor to rotate, thereby driving the telescopic rod to extend and retract. Here, the present application does not limit the specific form of the driving device 210, as long as it can drive the locking member 220 to perform telescopic movement.

[0048] The elastic member 300 is installed in the accommodating cavity. Figure 3 The elastic member 300 may be a spring, a torsion spring, a tension spring, etc., which is not limited in the present application. The lock hook 400 is slidably disposed in the accommodating cavity. The lock hook 400 is transmission-connected to the elastic member 300 and can extend or retract at the opening 140. Figure 3 As exemplarily shown in FIG, the elastic member 300 is configured as a spring, and one end of the elastic member 300 abuts against the housing, and the other end abuts against the lock hook 400. In some implementations of the present application, the lock hook 400 is provided with a first locking structure 450 and a second locking structure 460, and the first locking structure 450 and the second locking structure 460 are arranged sequentially in the extension direction of the lock hook 400.

[0049] The baffle 700 is disposed in the accommodating cavity, and is used to limit the sliding state of the lock hook 400, so that the lock hook 400 switches between the hidden state, the locked state and the open state in sequence. It should be noted that the baffle 700 includes but is not limited to metal components such as aluminum, copper, and stainless steel.

[0050] In some embodiments of this application, please refer to Figure 5The blocking piece 700 includes a mounting portion 710 and a first connecting portion 720 and a second connecting portion 730 located on opposite sides of the mounting portion 710. The mounting portion 710 is hingedly connected to the housing 100, and the first connecting portion 720 is transmission-connected to the locking member 220. In some embodiments of the present application, a card slot 221 is provided on the locking member 220, and the first connecting portion 720 is inserted into the card slot 221. When the driving device 210 drives the locking member 220 to slide and release the restriction on the lock hook 400, the lock member 220 drives the first connecting portion 720 to move, thereby driving the second connecting portion 730 to rotate, and the second connecting portion 730 acts on the lock hook 400 to limit the sliding state of the lock hook 400.

[0051] Specifically, see Figure 3 When the driving device 210 drives the locking member 220 to act on the first locking structure 450, the lock hook 400 is accommodated in the accommodating cavity and is in a hidden state. The driving device 210 drives the locking member 220 to retract, thereby releasing the restriction on the first locking structure 450. At this time, the elastic member 300 drives the lock hook 400 to extend from the opening 140. At this time, the blocking piece 700 will be driven by the locking member 220 to rotate around the mounting portion 710, so that the second connecting portion 730 acts on the second locking structure 460 of the lock hook 400. Then, the driving device 210 drives the locking member 220 to extend again, and the locking member 220 drives the blocking piece 700 to rotate, so that the second connecting portion 730 releases the restriction of the lock hook 400. The elastic member 300 continues to drive the lock hook 400 to pop out, and the locking member 220 acts on the second locking structure 460. At this time, the lock hook 400 is in a locked state. Please refer to Figure 4 The driving device 210 drives the locking member 220 again, so that the locking member 220 releases the restriction on the second locking structure 460, and the elastic member 300 drives the locking hook 400 to continue to extend from the opening, and the locking hook 400 is in an open state.

[0052] Based on the lock device of the embodiment of the present application, the blocking piece 700 can restrict the lock hook 400 when the locking member 220 releases the restriction on the lock hook 400, thereby preventing the elastic member 300 from driving the lock hook 400 to pop out from the opening 140, so that the lock hook 400 can be switched in sequence among the hidden state, the locked state and the open state, which is convenient for users to use.

[0053] In some implementations of this application, see Figures 2 to 4 A limiting portion 180 is provided in the accommodating cavity, and the elastic member 300 drives the lock hook 400 to extend from the opening 140. After the lock hook 400 moves into position, when the second locking structure 460 abuts against the limiting portion 180, the lock hook 400 is in an open state.

[0054] In some other implementations, the lock hook 400 may also be provided with a third locking structure (not shown), and the first locking structure 450, the second locking structure 460 and the third locking structure are arranged in sequence in the extension direction of the lock hook 400. When the locking mechanism 200 acts on the third locking structure, the lock hook 400 is in an open state.

[0055] Please also read Figure 3 and Figure 4 , taking the driving device 210 being configured to include an electromagnetic coil 212 and a reset member as an example, specifically, when the electromagnetic coil 212 is in a power-off state, the electromagnetic coil 212 has no force on the locking member 220, and under the action of the reset member, at least a portion of the locking member 220 extends from the electromagnetic coil 212 and abuts against the first locking structure 450, and the lock hook 400 is accommodated in the accommodating cavity, so that the embodiment of the present application can hide the lock hook 400 in the accommodating cavity when not in use.

[0056] When it is needed, the power source 510 supplies power to the electromagnetic coil 212. When the electromagnetic coil 212 is in a powered state, the electromagnetic coil 212 generates a magnetic force, and the magnetic force is greater than the pulling force of the reset member on the locking member 220, so that at least a part of the locking member 220 is retracted into the electromagnetic coil 212. At this time, the locking member 220 has no limiting effect on the first locking structure 450, and the lock hook 400 is extended from the opening 140 under the elastic drive of the elastic member 300. At this time, the blocking piece 700 will be driven by the locking member 220 to rotate around the mounting portion 710, so that the second connecting portion 730 acts on the second locking structure 460 of the lock hook 400. Then, the power supply 510 cuts off the power to the electromagnetic coil 212. When the magnetic force disappears, the reset member drives the locking member 220 to reset. The locking member 220 drives the blocking piece 700 to rotate, so that the second connecting portion 730 releases the restriction of the lock hook 400. The elastic member 300 continues to drive the lock hook 400 to pop out. The locking member 220 acts on the second locking structure 460. At this time, the lock hook 400 is in a locked state.

[0057] Next, the power source 510 supplies power to the electromagnetic coil 212 again, and the electromagnetic coil 212 generates magnetic force, and drives at least a portion of the locking member 220 to retract into the electromagnetic coil 212, and the elastic member 300 drives the lock hook 400 to continue to extend from the opening 140. When the second locking structure 460 abuts against the limiting portion 180, the lock hook 400 and the housing 100 form an open state, and the lock hook 400 can be mounted on the device that needs to be locked. Please refer to Figure 7 In order to facilitate the locking hook 400 to be mounted on an external device, the locking hook 400 can rotate in the accommodating cavity when it is in the open state.

[0058] When the lock hook 400 needs to be locked, the locking member 220 is retracted by controlling the electromagnetic coil 212. The user presses the lock hook 400 by hand to compress the elastic member 300, so that the lock hook 400 can be retracted into the accommodating cavity. After the electromagnetic coil 212 is powered off, the locking member 220 rests on different locking structures, and the lock hook 400 can be switched to a hidden state or a locked state.

[0059] In some embodiments of this application, please refer to Figure 5 The second connection part 730 has a first connection end 731 and a second connection end 732 in the width direction EE, the first connection end 731 is close to the opening 140, and the second connection end 732 is far away from the opening 140, wherein the end surface of the second connection part 730 away from the first connection part 720 is tilted outwardly in the direction from the first connection end 731 to the second connection end 732. In this way, the end surface of the second connection part 730 away from the first connection part 720 can be tilted, thereby facilitating the second connection part 730 to restrict the lock hook 400, and also facilitating the second connection part 730 to leave the lock hook 400 and release the restriction on the lock hook 400.

[0060] In summary, in the embodiment of the present application, the driving device 210, the locking member 220 and the elastic member 300 cooperate with the lock hook 400, so that the lock hook 400 has three states: hidden, locked and opened. Figure 6 When the lock hook 400 is not in use, it can be stored in the accommodating cavity to protect the lock hook 400 and reduce the occupied space. When it is needed, the lock hook 400 can be quickly ejected from the accommodating cavity for easy use.

[0061] In order to facilitate the control of different states of the lock hook 400, the embodiment of the present application also includes a main control board 520, which is installed in the accommodating cavity and electrically connected to the power supply 510, wherein the electromagnetic coil 212 is controlled by the main control board 520. In this way, when in use, the power-on state of the electromagnetic coil 212 is controlled by controlling the main control board 520, and then the lock hook 400 can be controlled to be in a hidden, locked or open state.

[0062] In some structural forms, the embodiments of the present application also include a fingerprint recognition module 600. The fingerprint recognition module 600 is installed on the outer surface of the housing 100 and is electrically connected to the main control board 520. The fingerprint recognition module 600 is used to control the working state of the electromagnetic coil 212. The user enters the user's fingerprint in the fingerprint recognition module 600 in advance. When using it, there is no need to carry or remember keys, passwords, etc., and the lock can be opened by simply identifying the fingerprint, so that it can be more convenient and quick in daily use. Moreover, the fingerprint recognition module 600 can be centrally managed and controlled through the management system. The administrator can add, delete and modify the fingerprint information of authorized users, and flexibly control who can access specific locks. In addition, the fingerprint recognition lock can record the fingerprint information of each unlocking to realize the audit and tracking of the unlocking history. Compared with traditional key or password locks, fingerprint recognition locks provide a higher level of security and eliminate the trouble of carrying keys or remembering passwords.

[0063] Specifically, the fingerprint recognition module 600 is installed on the outer surface of the housing 100. The fingerprint recognition module 600 is electrically connected to the main control board 520 and is used to control the working state of the electromagnetic coil 212. When in use, the user presses the fingerprint recognition module 600, and the fingerprint recognition module 600 transmits a signal to the main control board 520. The main control board 520 controls the power supply 510 to energize the electromagnetic coil 212 and the energization time, so that the locking member 220 can retract and release the restriction on the first locking structure 450, and then quickly extends under the action of the reset member to restrict the second locking structure 460, so that the lock hook 400 is in a locked state. The user presses the fingerprint recognition module 600 again, and the fingerprint recognition module 600 transmits a signal to the main control board 520. The main control board 520 controls the power supply 510 to energize the electromagnetic coil 212 and the energization time, so that the locking member 220 can retract and release the restriction on the second locking structure 460.

[0064] For further information, see Figure 8 The fingerprint recognition module 600 is disposed in the middle of the housing 100. In this way, when the power supply 510 is turned off, the fingerprint recognition module 600 on the front of the product and the back of the product can be held by hand, so that the product can be rotated 360 degrees, thereby improving the entertainment and fun of the embodiment of the present application.

[0065] In order to facilitate the control of different states of the lock hook 400, the embodiment of the present application further includes a wireless communication module (not shown in the figure), which is installed on the main control board 520. Specifically, the user can transmit a signal to the wireless communication module through the control device or the user terminal, and the wireless communication module then transmits a signal to the main control board 520, so as to control the working state of the driving device 210, thereby facilitating the use of the embodiment of the present application. The wireless communication module can be a Wi-Fi module, a Bluetooth module, a Zigbee module, an NFC module, etc., which is not limited in the present application.

[0066] It can be understood that the fingerprint recognition module 600 and the wireless communication module can be provided separately or in combination.

[0067] The embodiment of the present application also includes an indicator light 810, which is installed on the outer surface of the housing 100 and is used to indicate the power of the power supply 510. Among them, multiple indicator lights 810 can be set, and each indicator light 810 represents a different power range of the power supply 510. By lighting up different numbers of indicator lights 810, the user can intuitively understand the remaining power of the power supply 510 and take corresponding measures such as charging or replacing the battery in time. In some other embodiments, the remaining power of the power supply 510 can also be displayed by adding LED lights of different colors to the indicator light 810. For example, when the power is sufficient, the indicator light 810 can display green; when the power is low, the indicator light 810 can display orange or yellow; when the power is extremely low, the indicator light 810 can display red to remind the user to charge in time. In this way, the user can easily understand the current state of the power supply 510 and make corresponding processing at any time.

[0068] The embodiment of the present application also includes a charging interface 820, which is installed on the housing 100 and is used to charge the power supply 510. The charging interface 820 can be a Micro USB interface or a Type-C interface, or a magnetic charging interface 820, etc. The specific charging structure can be selected and set according to the specific needs and design requirements of the power supply 510, as well as the user's usage habits and needs, and the present application does not limit this.

[0069] In some structural forms, please refer back to Figure 3 and Figure 4 The chute 150 and the installation cavity 170 are arranged in parallel in the accommodating cavity, the main control board 520 and the power supply 510 are arranged in the installation cavity 170, and at least part of the lock hook 400 slides in the chute 150. In this way, the internal space of the accommodating cavity can be reasonably utilized, making the structure of the embodiment of the present application more compact and occupying less space. In some structural forms, a baffle can be arranged in the accommodating cavity, and the installation cavity 170 and the chute 150 are separated on both sides of the baffle.

[0070] In order to facilitate the control of the lock hook 400 to work, the lock hook 400 includes a lock rod 410 and a hook body 420 connected to each other. One end of the elastic member 300 is connected to the lock rod 410, and the other end is connected to the housing 100. The hook body 420 can be a U-shaped structure or a C-shaped structure. One end of the hook body 420 is fixedly connected to the lock rod 410, and when the other end is fixed in the accommodating cavity, the lock hook 400 is in a locked state. When the other end extends from the accommodating cavity, the lock hook 400 is in an open state. When the lock hook 400 is in the open state, the lock rod 410 can rotate in the accommodating cavity.

[0071] In some structural forms, see Figure 2 and Figure 3 The outer diameter of the locking rod 410 is smaller than the outer diameter of the hook body 420. An annular protrusion 430 is provided at one end of the locking rod 410 close to the hook body 420, and a first locking structure 450 is formed between the annular protrusion 430 and the locking rod 410, wherein the annular protrusion 430 can be integrally formed with the locking rod 410, or can be processed separately and then assembled on the locking rod 410, which is not limited in the present application.

[0072] See also Figures 2 to 4 The lock hook 400 further includes a stopper 440, which is connected to an end of the lock rod 410 away from the hook body 420. In some embodiments, the outer diameter of the stopper 440 is greater than the outer diameter of the lock rod 410, so that a second locking structure 460 can be formed. In other embodiments, the stopper 440 can be provided with a plurality of sections of a column, and by designing the difference in the outer diameters of the plurality of sections of the column, the second locking structure 460 and the third locking structure can be formed.

[0073] In some embodiments, please refer to Figure 2 and Figure 8, the embodiment of the present application also includes an ignition device 910 and a key switch 920. The ignition device 910 is installed in the accommodating cavity. The outer surface of the housing 100 is provided with an ignition port 160 for the ignition device 910 to generate sparks. The ignition port 160 is located at one end away from the opening 140. In some structural forms, the ignition device 910 may include an ignition high-voltage package, which generates sparks by connecting to the power supply 510. When working, press the key switch 920, and then the power supply 510 will provide the required current and voltage to drive the ignition high-voltage package. A spark plug device may be included in the ignition high-voltage package. The spark plug is composed of two electrodes, and there is a certain gap between them. When the power supply 510 is turned on, the current will flow through the ignition high-voltage package and pass through the electrodes of the spark plug. When this current flows through the electrodes, the molecules in the air are excited and ionized under the action of electric shock. The gap between the electrodes is filled with ionized air, thus forming a conductive channel. When the current reaches a high enough energy, the electric shock passes through the conductive path, forming a short and strong arc discharge. The high temperature and energy generated by the arc discharge can ignite cigarettes or paper. In this way, the lock of the embodiment of the present application can also ignite and provide a fire source, thereby increasing the diversity of the lock's use.
