Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a novel lock. Background Technology

[0002] In public places such as hospitals, airports, and large shopping malls, shared wheelchairs are usually provided to facilitate people with mobility impairments. To ensure that wheelchairs are properly returned and managed when not in use, and to prevent them from being parked haphazardly or lost, special locks are typically used to secure them. Traditional wheelchair locks mostly use mechanical lock structures, requiring administrators to use physical keys to open and close them, resulting in low management efficiency and the risk of keys being copied or lost. With the development of technology, electronically controlled smart lock systems have emerged. These systems typically use a reading module (such as an RFID reader) inside the lock body and an identifier (such as an RFID tag) installed at a specific location on the wheelchair as a "key." When returning the wheelchair, the identifier is brought close to or inserted into the lock body. After the lock body recognizes the valid information, it controls an actuator to lock the identifier or a part of the wheelchair.

[0003] In many existing publicly available electronic lock solutions, the actuator for locking the "key" (i.e., the identification carrier) often uses a micro-motor. For example, the motor drives a worm gear or rack and pinion mechanism to extend and retract a latch or pin, thereby securing and releasing the key. However, using a motor as the drive source has some inherent drawbacks: First, the purchase cost of motors is relatively high, increasing the manufacturing cost of the entire lock system; second, the actuator structure, consisting of a motor, reduction mechanism, and transmission components, is complex, occupying a large space and hindering the miniaturization of the lock body. Furthermore, the complex mechanical structure leads to a higher failure rate and maintenance requirements; third, motors typically produce noise during operation and have relatively high power consumption during continuous stall or operation, posing a challenge to battery-powered outdoor or wireless applications. Utility Model Content

[0004] Therefore, it is necessary to provide a new type of lock to address the technical shortcomings of existing electric locks that use motor drives.

[0005] A novel lock includes a lock body and a key that engages with the lock body. The key is installed on a shared device, and the lock body is installed on a lock body post. The lock body includes a housing, and a circuit board, a battery, and an electronic lock are disposed inside the housing. The housing includes a main shell and a bottom cover. The main shell has a slot for engaging the key, and the key has a keyhole for engaging the electronic lock. The key is equipped with an RFID chip, the circuit board includes an RFID reader module, the RFID reader module is used to identify the RFID chip, and the battery is used to power the circuit board. The circuit board is used for: When it is necessary to lock the key, the electric lock is powered on, causing the actuating arm of the electric lock to magnetically attract and pass through the keyhole; When it is necessary to unlock the key, the electric lock is powered down, causing the locking arm to reset and disengage from the keyhole.

[0006] When using the aforementioned new lock, if the shared device needs to be returned, the key is inserted into the slot of the main housing, and the RFID reader module on the circuit board can identify the RFID chip. If the target shared device is identified, the electronic lock is powered on, causing the locking arm to magnetically attract and pass through the keyhole, thus locking the shared device. If the shared device needs to be borrowed, the user initiates a borrowing request by scanning a QR code. If the borrowing request is compliant, the circuit board powers off the electronic lock, causing the locking arm to reset and disengage from the keyhole, thus unlocking the shared device for the user. It can be seen that compared to the existing motor-driven solutions, this new lock eliminates the complex motor, reduction gears, and transmission mechanism, offering a series of technical advantages such as simplified structure, significantly reduced cost, rapid response, low energy consumption, and low operating noise.

[0007] In one embodiment, the housing includes a main shell and a bottom cover, the main shell and the bottom cover are fixedly connected, and the lock body is mounted on a lock body stake through the bottom cover.

[0008] In one embodiment, the bottom cover includes a bottom cover body and a battery cover, wherein the battery cover and the bottom cover body are detachably connected.

[0009] In one embodiment, the bottom cover body is provided with a USB port that mates with the circuit board, the USB port being used to supply power to the circuit board or to transmit data.

[0010] In one embodiment, the bottom cover body is provided with a serial interface that mates with the circuit board. The serial interface is used to electrically connect with the secondary lock, which is a synchronous lock that locks or unlocks synchronously with the lock body.

[0011] In one embodiment, a fixing plate is also included, through which the electronically controlled lock is fixedly connected to the main housing.

[0012] In one embodiment, the fixing plate includes a first fixing plate and a second fixing plate, and the electronic lock is installed between the first fixing plate and the second fixing plate.

[0013] In one embodiment, the main housing includes a first chamber, a second chamber, and a third chamber, with the battery installed in the first chamber, the electronic lock installed in the second chamber, and the circuit board installed in the third chamber.

[0014] In one embodiment, the circuit board includes a wireless connection module, through which the circuit board connects to a server; The casing is affixed with a QR code, which is used for users to interact with the server.

[0015] In one embodiment, a speaker is also included, which is electrically connected to the circuit board, and the main housing is provided with a sound outlet that mates with the speaker. Attached Figure Description

[0020] This utility model discloses a novel lock.

[0021] like Figures 1 to 4 As shown, the new type of lock includes a lock body 10 and a key 20 that cooperates with the lock body 10. The key 20 is installed on the shared equipment, and the lock body 10 is installed on the lock body post. The lock body 10 includes a housing 11. The housing 11 contains a circuit board 12, a battery 13, and an electric lock 14. The housing 11 includes a main shell 111 and a bottom cover 112. The main shell 111 has a slot 1111 for cooperating with the key 20, and the key 20 has a keyhole 21 for cooperating with the electric lock 14. The key 20 is equipped with an RFID chip 22. The circuit board 12 includes an RFID reader module for identifying the RFID chip 22, and the battery 13 is used to power the circuit board 12.

[0022] The circuit board 12 is used to: control the electric lock 14 to be powered on when the key 20 needs to be locked, so that the actuating arm of the electric lock 14 is magnetically attracted and passes through the keyhole 21; and control the electric lock 14 to be powered off when the key 20 needs to be unlocked, so that the actuating arm of the electric lock 14 is reset and disengaged from the keyhole 21.

[0023] When using the aforementioned new lock, if the shared device needs to be returned, the key is inserted into the slot of the main housing, and the RFID reader module on the circuit board can identify the RFID chip. If the target shared device is identified, the electronic lock is powered on, causing the locking arm to magnetically attract and pass through the keyhole, thus locking the shared device. If the shared device needs to be borrowed, the user initiates a borrowing request by scanning a QR code. If the borrowing request is compliant, the circuit board powers off the electronic lock, causing the locking arm to reset and disengage from the keyhole, thus unlocking the shared device for the user. It can be seen that compared to the existing motor-driven solutions, this new lock eliminates the complex motor, reduction gears, and transmission mechanism, offering a series of technical advantages such as simplified structure, significantly reduced cost, rapid response, low energy consumption, and low operating noise.

[0024] The main shell 111 is fixedly connected to the bottom cover 112, and the lock body 10 is installed on the lock body stake through the bottom cover 112. Installing the lock body 10 on the lock body stake through the bottom cover 112 enhances the overall structural strength and stability of the lock body 10, while also making on-site installation more convenient, requiring only the bottom cover 112 to be fixed.

[0025] Furthermore, the bottom cover 112 includes a bottom cover body 1121 and a battery cover 1122, which is detachably connected to the bottom cover body 1121. By providing a detachable battery cover 1122, the battery 13 can be replaced very easily without disassembling the entire lock body 10, greatly reducing the difficulty and time cost of later maintenance.

[0026] Furthermore, the bottom cover body 1121 is provided with a USB port 11211 that mates with the circuit board 12. The USB port 11211 is used to supply power to the circuit board 12 or to transmit data. By setting up the USB port 11211, it can serve as a backup or continuous power supply channel, improving power supply flexibility and preventing system failure due to the battery 13 running out of power. On the other hand, it can also serve as a data interface for program debugging, firmware upgrades, or data export, improving the maintainability and intelligence level of the product.

[0027] Furthermore, the bottom cover body 1121 is provided with a serial interface 11212 that mates with the circuit board 12. The serial interface 11212 is used for electrical connection with the secondary lock, which is a synchronous lock that locks or unlocks synchronously with the lock body 10. The secondary lock can be connected through the serial interface 11212, realizing the synchronous control capability of "one master and multiple slaves". This is particularly useful in application scenarios that require fixing large equipment or multiple points. Multiple locking points can be managed with one control core (master lock), which greatly improves the scalability and economy of the system.

[0028] The new type of lock also includes a fixing plate 15, through which the electric lock is fixedly connected to the main housing 111. By adding a special fixing plate 15 to install the electric lock 14, the electric lock 14 can be more securely installed on the main housing 111, preventing it from loosening due to long-term operation or external vibration, thus improving the mechanical reliability and service life of the entire lock.

[0029] Furthermore, the fixing plate 15 includes a first fixing plate 151 and a second fixing plate 152, and the electric lock is installed between the first fixing plate 151 and the second fixing plate 152. By using the first fixing plate 151 and the second fixing plate 152 to clamp the electric lock 14 in the middle, the electric lock 14 is subjected to more even force and is more reliably fixed. This can effectively disperse the reaction force generated when the actuator arm engages and resets, further ensuring the stability of the electric lock 14 during operation.

[0030] The main casing 111 includes a first chamber 1112, a second chamber 1113, and a third chamber 1114. The battery 13 is installed in the first chamber 1112, the electric lock 14 is installed in the second chamber 1113, and the circuit board 12 is installed in the third chamber 1114. Dividing the interior of the main casing 111 into three independent chambers achieves physical isolation and professional layout of the battery 13, the electric lock 14, and the circuit board 12. This facilitates internal wiring and heat dissipation, prevents mutual interference between components, and makes assembly and production more organized, thereby improving the internal quality of the product.

[0031] The circuit board 12 includes a wireless connection module, which connects to the server. A QR code is affixed to the housing 11, allowing users to interact with the server. By integrating the wireless connection module and the QR code, the lock gains remote communication and user interaction capabilities, enabling unmanned and intelligent remote management (such as monitoring lock status and remote control), and providing a standardized user operation interface (scanning the code to borrow / return), greatly improving user experience and management efficiency. Furthermore, the wireless connection module uses 4G or Bluetooth technology for wireless communication.

[0032] The new lock also includes a speaker, which is electrically connected to the circuit board 12. The main housing 111 has a sound outlet 1115 for the speaker. By adding a speaker, clear operation feedback (such as "locking successful", "please return") and system status (such as "low battery" or "malfunction") can be conveyed to the user through voice prompts or different sound effects, making up for the shortcomings of purely visual prompts (such as indicator lights) that may be overlooked, and improving the user-friendliness and ease of use of the product.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
