Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically a modular IoT lock. Background Technology

[0002] With technological advancements, intelligentization and electronicization are the main development trends of locks. To facilitate lock development and flexibly adapt to various usage scenarios, locks are designed as multi-module devices. For example, the lock disclosed in application number CN 201980052578.2 mainly includes a lock body (a latch module in the document) and a reader module. The reader module is used for human-computer interaction (such as password, fingerprint recognition, card recognition, Bluetooth recognition, or facial recognition) and electronic control of the lock body. The reader module is detachably connected to the lock body. Specifically, a reader connector is provided at the end of the reader module, with a pair of L-shaped tracks formed on it. A latch connector is provided at the end of the lock body, with a channel on it. The L-shaped tracks slide into the channel to engage the reader module with the end of the lock body. This allows the lock body to be matched with reader modules of different functional forms.

[0003] However, the aforementioned locks still have room for design optimization. For example, the reading module can integrate identification and control functions, thus allowing for further modularization to achieve more flexible applications. Currently, designs have been developed that combine an identification module and a main control module in the reading module. The identification module is typically attached to the lock seat of the lock body, which is usually connected to a mounting plate. The lock seat and plate work together to clamp the lock onto the cabinet door, and the main control module is detachably attached to the plate. Furthermore, the design of the connection structure between the reading module and the lock body is flawed, leading to insufficient assembly reliability. Therefore, the modular design of the reading module also raises questions about the rationality of the installation structure of the identification module and the main control module. The following sections will discuss the optimized design of the connection structure between the identification module and the lock seat, as well as the optimized design of the connection structure between the main control module and the plate. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a modular interlocking system that is firmly and reliably assembled and dustproof and reliably sealed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A modular IoT lock includes a lock body, a pressure plate, an identification module, and a main control module. The pressure plate is connected to the bottom of the lock seat of the lock body. The identification module is detachably installed on the lock seat, and the main control module is detachably installed on the pressure plate. The lock seat has an L-shaped latching seat protruding at one end. A through-hole is provided at the corner of the L-shaped latching seat. The L-shaped latching seat includes a latching protrusion protruding at one end of the lock seat and a support plate arranged in an L-shape with the latching protrusion. A stepped groove is formed at the latching protrusion of the lock seat. An L-shaped latching cavity is formed on the housing of the identification module. The identification module is detachably connected to the L-shaped latching seat after being covered by the L-shaped latching cavity. The L-shaped latching cavity includes an end groove for inserting the latching protrusion and a bottom groove for embedding the support plate. An end plate forming the end groove on the housing of the identification module is latched into the stepped groove, and the end face of the end plate is axially aligned with the axial end face of the stepped groove.

[0006] Preferably, the support plate has a positioning recess on each of the two lateral sides near the snap-fit ​​protrusion, and a positioning boss protruding into the stepped groove is provided in the housing of the identification module, and the positioning bosses are inserted into the positioning recesses one by one.

[0007] Preferably, the pressure plate includes a base plate with a surrounding edge around the base plate. The end face of the surrounding edge is a mounting surface that corresponds to and mates with the lock seat. The base plate of the pressure plate has a module mounting hole, which corresponds to the position of the support plate. The module mounting hole is connected to the box cavity formed by the surrounding edge. The main control module is installed in the module mounting hole and partially extends into the box cavity of the pressure plate.

[0008] Preferably, one end of the module mounting hole is provided with an insertion port, and the other end of the module mounting hole is provided with a screw connector. One end of the main control module housing is provided with a tongue, and the other end of the main control module housing is provided with a connecting ear. The tongue at one end of the main control module is inserted into the insertion port, and the connecting ear at the other end of the main control module is aligned with the screw connector and fastened with a screw.

[0009] By adopting the above technical solution, the L-shaped snap-fit ​​seat at the end of the lock seat forms an installation platform, enabling a secure and reliable installation of the identification module. This provides a more stable support effect compared to traditional end-joint designs. Furthermore, the L-shaped snap-fit ​​seat's structural design, combined with the identification module's housing, forms a corresponding L-shaped snap-fit ​​groove. The identification module's housing, after being placed on the L-shaped snap-fit ​​seat, ensures a secure and reliable installation of the identification module on the lock seat, resulting in a tight fit. The overall lock structure is compact and aesthetically pleasing, with no exposed or obvious gaps, thus improving the overall dustproof and sealing performance of the lock. Additionally, the identification module's housing has sufficient width to facilitate the installation and arrangement of internal components. Moreover, after the main control module is installed, the pressure plate provides reliable protection.

[0010] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description
