Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, specifically relating to a main control module and a door lock. Background Technology

[0002] For ease of installation, existing smart door locks typically house the circuit board, power supply, and actuator all within a single housing. The housing is then inserted into the mounting slot of the door panel. After installing accessories such as the door handle, the mounting slot is sealed with a sealing plate.

[0003] However, the circuit boards of existing smart door locks are single-board structures. Once a component on the board fails, it is necessary to disassemble the door handle, sealing plate, etc., and then remove the entire housing from the mounting slot of the door panel to repair or replace the faulty component or circuit board, which is a rather cumbersome operation. Utility Model Content

[0004] The purpose of this utility model is to provide a main control module and a door lock to solve the technical problem of inconvenient maintenance of existing smart door lock circuit boards.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] See Figures 1 to 5 In one embodiment, the main control module includes:

[0040] The frame 1 has a circuit board mounting slot 11 inside; one side of the frame 1 has an opening 12 communicating with the circuit board mounting slot 11; the inner end of the circuit board mounting slot 11 has a first mounting part 111; the outer end of the circuit board mounting slot 11 has a second mounting part 112 communicating with the opening 12; an interface board 2 is mounted on the first mounting part 111; and a main control board 3 is mounted on the second mounting part 112; and the main control board 3 and the interface board 2 are detachably connected.

[0041] In this embodiment, optionally, the main control board 3 may be equipped with one or more of the following: MCU, card reader chip, storage chip, clock chip, and motor control module; the interface board 2 may be equipped with several interfaces 23 for connecting to power modules, motors, and other devices.

[0042] In some application scenarios, some components on the main control board 3 are more prone to failure or damage. In this embodiment, preferably, by installing the interface board 2 at the inner end of the circuit board mounting slot 11 and the main control board 3 at the outer end of the circuit board mounting slot 11, when a failure occurs and repair or replacement is required, only the main control board 3 needs to be removed from the opening 12, without disassembling the entire main control module.

[0043] See Figure 2 , Figure 4 and Figure 5 As an optional embodiment of the first mounting part 111, the first mounting part 111 includes a plurality of mounting posts 1111 for cooperating with the interface plate 2; the mounting posts 1111 are provided with first fixing holes 1112; the interface plate 2 is provided with second fixing holes 21 corresponding to the first fixing holes 1112.

[0044] In this embodiment, the interface plate 2 can be fixedly installed on the mounting post 1111 by passing screws through the second fixing hole 21 and the first fixing hole 1112 in sequence.

[0045] Of course, in other embodiments, the first mounting part 111 can be in other forms, such as directly opening mounting holes in the circuit board mounting slot 11; or, the first mounting part 111 can be configured to be plugged into or snapped into the interface board 2.

[0046] See Figure 2 , Figure 3 and Figure 5 In order to facilitate the installation and removal of the main control board 3, as a preferred embodiment of the second mounting part 112, the second mounting part 112 includes a plurality of sliding grooves 1121 disposed on the inner wall of the circuit board mounting groove 11; the sliding grooves 1121 are used to accommodate the corresponding side of the main control board 3.

[0047] In this embodiment, the sliding groove 1121 is provided at the outer end of the circuit board mounting groove 11. After the main control board 3 enters through the opening 12, the side of the main control board 3 is inserted into the corresponding sliding groove 1121, and can continue to be inserted into the circuit board mounting groove 11 along the sliding groove 1121 until it is connected to the interface board 2.

[0048] Furthermore, there are two sliding grooves 1121, respectively disposed on the upper and lower walls of the circuit board mounting groove 11. In other words, the upper and lower sliding grooves 1121 are used to accommodate the upper and lower sides of the main control board 3, respectively. Of course, in other embodiments, the sliding grooves 1121 can be disposed on the side wall of the circuit board mounting groove 11, and the main control board 3 can be provided with protrusions that cooperate with the sliding grooves 1121.

[0049] Furthermore, the sliding groove 1121 is provided with a flared part 11211 at the end near the opening 12, which facilitates the guidance of the side of the main control board 3 into the corresponding sliding groove 1121.

[0050] Optional, see Figure 4 As an optional embodiment where the main control board 3 and the interface board 2 are detachably connected, the main control board 3 is provided with a pin portion 31; the interface board 2 is provided with a socket portion 22 that mates with the pin portion 31. When the main control board 3 is inserted into the circuit board mounting slot 11 along the sliding groove 1121, the pin portion 31 can be inserted into the socket portion 22, thereby connecting the main control board 3 and the interface board 2.

[0051] Optionally, a power module 13 may also be provided on the frame 1. The power module 13 may be connected to the interface 23 on the interface board 2 via wires.

[0052] Accordingly, see Figure 5 One embodiment of this application provides a door lock, including: a fixing plate 100; an unlocking module 200 disposed inside the fixing plate 100; and a main control module 300 as described above disposed inside the fixing plate 100; wherein the fixing plate 100 is provided with a channel opening 101 corresponding to the opening 12.

[0053] In this embodiment, the unlocking module 200 and the main control module 300 can be installed side-by-side on the inner side of the fixing plate 100, forming a whole. This facilitates the installation of the whole into the mounting groove of the door plate when installing the door lock, and then the side sealing plate 500 is encapsulated on the outer side of the fixing plate 100. The unlocking module 200 may include a motor and other transmission components.

[0054] In this embodiment, optionally, the door lock also includes a handle 400 for cooperating with the unlocking module 200.

[0055] In this embodiment, the fixing plate 100 is provided with a channel opening 101 corresponding to the opening 12, which allows the main control board 3 to enter and exit.

[0056] For example, in one application scenario, when the main control board 3 needs to be repaired or replaced, only the side sealing plate 500 needs to be removed, and then the main control board 3 can be pulled out from the channel opening 101. There is no need to remove the handle 400 to take out the fixing plate 100, the unlocking module 200 and the main control module 300 as a whole.
