[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-3 As shown, this embodiment provides a lock, which includes a lock body 100, a latch 200, a bolt 300, a locking drive assembly 400, a micro switch 500, and a pop-out component. The bolt 300 is disposed on the lock body 100 and has a locking position for locking with the latch 200 and an unlocking position for disengaging from the latch 200. The locking drive assembly 400 is disposed on the lock body 100 and drives the bolt 300 to switch between the locking position and the unlocking position. The micro switch 500 is disposed on the lock body 100 and can be triggered when the bolt 300 is in the unlocking position. The micro switch 500 is communicatively connected to the locking drive assembly 400. The pop-out component is fixedly disposed relative to the lock body 100 or relative to the latch 200, and is used to move the latch 200 and the bolt 300 away from each other by a preset distance when the bolt 300 is in the unlocking position.

[0041] By configuring the lock body 100, the lock tongue 300, locking drive assembly 400, and micro-switch 500 are installed, improving the integration of the lock. Specifically, the lock tongue 300 has a locking position where it is locked to the latch 200 and an unlocking position where it is unlocked from the latch 200. The locking drive assembly 400 drives the lock tongue 300 to move between these two positions, thereby achieving locking and unlocking between the lock tongue 300 and the latch 200. Simultaneously, the lock also includes a micro-switch 500 that is communicatively connected to the locking drive assembly 400. When the lock tongue 300 is in the unlocking position, the micro-switch 500 is triggered, serving as a signal to stop the locking drive assembly 400 from driving. This ensures that the lock tongue 300 stops in the unlocking position promptly and accurately, avoiding mechanical set screw stalling. Furthermore, by increasing the current to the locking drive assembly 400, the drive of the locking drive assembly 400 is stopped, effectively reducing motor stalling and increased current consumption, extending the lock's lifespan, and reducing power consumption. In addition, the lock is also equipped with a pop-out mechanism. By setting the pop-out mechanism, after the latch 300 is in the unlocked position, the latch 200 and the latch 300 are separated by a preset distance. The setting of this preset distance can effectively prevent the lock from being accidentally locked, making it more convenient and user-friendly.

[0042] It is worth noting that the lock also includes a circuit board 110, which is powered by a dry cell battery. The micro-switch 500 and the locking drive assembly 400 are both electrically connected to the circuit board 110. Because the lock has low power consumption, it can be powered by a dry cell battery, making replacement easier and reducing costs. Furthermore, using a dry cell battery also helps reduce the lock's thickness and space requirements, making it suitable for devices with limited installation space. For example, the lock's thickness is approximately 18mm. The circuit board 110 is used to control the lock's unlocking and disengaging functions, resulting in a higher degree of automation and intelligence. Correspondingly, the lock body 100 also includes a battery mounting cavity and a cover plate 120, which covers the battery mounting cavity to ensure reliable battery installation.

[0043] Specifically, the circuit board 110 is equipped with a signal receiving module for receiving unlocking signals. For example, the unlocking signal can be emitted via RFID sensing, an electronic mobile device APP, or an electronic mobile device NFC, making the unlocking operation more convenient and diverse. It is understood that the circuit board 110 stores an unlocking program. When the unlocking program runs, the signal receiving module, the locking drive component 400, and the micro-motion component 500 can act accordingly to achieve the corresponding preset functions. Correspondingly, a sensing area is provided on the lock body 100 at the location corresponding to the signal receiving module, allowing users to unlock the lock by bringing an RFID key or mobile phone close to the sensing area.

[0044] Furthermore, the locking drive assembly 400 includes a drive member 410 and a cam 420. The cam 420 is disposed at the drive end of the drive member 410, and the drive end is used to drive the cam 420 to rotate. When the cam 420 rotates, it can drive the latch 300 to move from the locked position to the unlocked position. Specifically, when the major diameter of the cam 420 engages with the latch 300, the latch 300 is in the unlocked position; when the minor diameter of the cam 420 engages with the latch 300, the latch 300 is in the locked position. In addition, the micro-actuator 500 is communicatively connected to the drive member 410 so that when the micro-actuator 500 contacts the latch 300, the drive member 410 stops driving, thereby ensuring that the major diameter of the cam 420 just abuts against the latch 300. For example, the drive member 410 is a miniature geared motor.

[0045] Preferably, to ensure the reliability of the latch 300 being in the locked position, the lock also includes a reset member 600. The reset member 600 abuts against the latch 300, causing the latch 300 to tend to be in the locked position. It is understood that the reset member 600 not only improves the reliability of the latch 300 being in the locked position, but also drives the latch 300 to maintain contact with the cam 420 when the cam 420 rotates from its major radial direction to its minor radial direction, thereby improving the reliability of the contact between the cam 420 and the latch 300.

[0046] It is worth noting that the latch 300 of the lock is designed to be in an extended state in its natural state. When the drive unit 410 receives a drive signal, it drives the cam 420 to rotate. During the rotation of the cam 420, the cam 420 pushes the latch 300 to gradually retract until it disengages from the latch 200. At the same time, the drive unit 410 will hold the latch 300 in the locked position for a preset time. After the preset time has elapsed, the drive unit 410 will automatically reset, and the latch 300 will return to the locked position under the action of the reset unit 600, facilitating the next locking. The preset time can be set to 5s-10s.

[0047] Preferably, the circuit board 110 is further provided with a light guide column, and the light guide column is also provided with an indicator light 130. The indicator light 130 is set to a normally off state and starts to work when the dry cell battery power is lower than a preset power level. The working state can be constant on or flashing, used to prompt the user to replace the dry cell battery, so as to avoid the situation where the dry cell battery power is insufficient to unlock the door, resulting in unlocking failure. The indicator light 130 is set to LED, which has lower power consumption. The dry cell battery is set to AA battery. For example, two AA batteries will last for about 6 months if the lock is opened and closed 50 times a day. In addition, the unlocking procedure also limits the lock tongue 300 to always be in the unlocked position when the indicator light 130 is working, in order to avoid the situation where the dry cell battery power is exhausted, resulting in unlocking failure.

[0048] As an alternative solution for the lock, the latch 300 includes a sliding section 310 and a driving section 320 and a locking section 330 respectively disposed at both ends of the sliding section 310. The driving section 320 is used to cooperate with the locking drive assembly 400 and the micro-actuator 500. It should be noted that the driving assembly 410 and the micro-actuator 500 are positioned on opposite sides of the driving section 320 to avoid interference and optimize the internal space of the lock body 100, thereby reducing the size of the lock. The locking section 330 selectively protrudes from the lock body 100 to achieve locking with the latch 200. Correspondingly, the latch 200 has multiple locking surfaces 220 along the locking direction, and the locking section 330 of the latch 300 achieves locking by abutting against the locking surfaces 220. Exemplarily, both the latch 300 and the latch 200 are formed by sheet metal stamping and bending, which is convenient to process and has lower cost.

[0049] Optionally, the locking section 330 is slidably disposed within the lock body 100 along a first direction, the first direction being at an angle to the contact direction of the bolt 300 and the latch 200. For example... Figure 1 and Figure 2 As shown, the vertical direction is the locking direction. This configuration ensures that the force exerted by the ejector has a component in the first direction, and this component is consistent with the direction in which the latch 300 moves toward the unlock position, thus reducing the unlocking effort.

[0050] Preferably, both the locking section 330 and the latch 200 are provided with guide surfaces 210 that are inclined relative to the abutment direction. Through the cooperation of the two guide surfaces, the latch 200 and the lock hole 711 can be guided to lock together, making the user's locking operation more effortless.

[0051] In this embodiment, the lock also includes a mounting plate 700. One side of the mounting plate 700 has a mounting flange 710. Both the lock body 100 and the mounting plate 700 are mounted on the first locking member, with the mounting plate 700 covering the lock body 100. The mounting flange 710 has a lock hole 711 through which the latch 200 can pass to engage with the bolt 300. Optionally, the lock body 100 can also be mounted on the mounting plate 700, which is connected to the first locking member. By using the mounting plate 700, the lock body 100 and the first locking member are installed. Furthermore, after installation, all functional components are concealed, effectively preventing disassembly and prying, thus improving the lock's security and overall aesthetics.

[0052] Specifically, the lock body 100 is provided with a mounting ear 140, and the mounting ear 140 is provided with a mounting hole 141. The mounting component passes through the mounting hole 141 and is connected to the mounting plate 700. The connection is convenient and reliable, effectively reducing the possibility of installation failure of the lock body 100 and the latch 200 under bumpy and vibrating conditions.

[0053] This embodiment also discloses a device with a lock, including a first locking member and a second locking member, as well as a lock as described in any of the above embodiments. Specifically, a lock body 100 is disposed on the first locking member, and a latch 200 is disposed on the second locking member. The latch 200 is provided with a mounting hole 141 to achieve connection with the second locking member. Exemplarily, the device with the lock can be a box, cabinet, drawer, etc. Specifically, it can be a takeaway box. Because the lock structure is compact and does not require a large current, takeaway boxes equipped with the lock can be unlocked in more ways, and the unlocking operation is more convenient; at the same time, it has higher security, better aesthetics, lower power consumption, and longer operating time with a single dry cell battery.

[0054] Optionally, the first locking member and the second locking member are rotatably connected by a pivot, and the pop-out member is set as a magnetic or elastic member. The magnetic force or the restoring force of the spring is used to move the first and second locking members away from each other, thereby creating a preset distance between the latch 200 and the bolt 300. Optionally, the pop-out member is positioned close to the lock for easier operation. In this embodiment, the pop-out member is a spring, installed on the second locking member, and located on both sides of the latch 200.

[0055] In other embodiments, the pop-out element is configured as a torsion spring, which is sleeved on the pivot so that the first locking element and the second locking element are separated from each other when the lock is in the unlocked state, thereby avoiding accidental locking of the lock.

[0056] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
