Description

Technical Field

[0001] This invention relates to the field of lock-related technology, and in particular to an electronic lock equipped with internal and external modules. Background Technology

[0002] In today's society, intelligent electronic products are gradually permeating all aspects of our lives, and intelligent electronic locks are one of the most popular types. These electronic locks achieve efficient and convenient locking and unlocking functions through electric drive mechanisms, greatly improving security and convenience. However, a stable power supply is indispensable for the normal operation of electronic locks. Traditional electronic lock designs often install the power module and the electrical component module on the inner and outer sides of the door leaf respectively, and connect them via flexible signal cables. While this design meets functional requirements to some extent, it is relatively cumbersome during actual installation. Furthermore, because the signal cables are in constant use, they are prone to performance degradation due to wear and aging, thus affecting the overall performance of the electronic lock.

[0003] To address the aforementioned technical problems, existing patent 202022643641.2 proposes a door lock and a door containing the same. The door lock includes a first handle, a second handle, and a second handle base cover. The first handle includes a first contact circuit board with a first contact point, an insulating stud, and a flexible conductive medium, wherein the flexible conductive medium is a spring. The flexible conductive medium is embedded in the insulating stud and one end is in contact with the first contact point. The second handle includes a second contact circuit board with a second contact point and a through-hole conductive fixing screw. The through-hole conductive fixing screw is fixed to the second handle base cover and one end is in contact with the second contact point. When the first and second handles are installed on the door, the flexible conductive medium embedded in the insulating stud contacts the through-hole conductive fixing screw to conduct electricity. This utility model patent solution achieves the transfer of current from the first handle to the second handle without the need for additional connection interfaces, improving installation efficiency. However, it should be noted that the spring is made of a metal wire with a circular cross-section. Therefore, the tail end of the soft conductive medium made of the spring is in line contact with the head end wall of the conductive fixing screw, resulting in a relatively small conductive area. This increases the risk of unstable electrical signal transmission or failure of the electronic lock during long-term use. Summary of the Invention

[0004] One of the pressing technical problems this invention needs to solve is how to provide an electronic lock that is easy to install and can optimize the stability of electrical signal transmission. Therefore, this invention proposes an electronic lock configured with inner and outer modules, including a first module and a second module respectively installed on the inner and outer sides of a door leaf. The first module includes a first outer shell and a first circuit board housed within the first outer shell. The second module includes a second outer shell and a second circuit board housed within the second outer shell. The first module further includes a first conductive contact disposed on the first circuit board and a first conductive post electrically connected to the first conductive contact. The second module further includes a second conductive contact disposed on the second circuit board and a second conductive post electrically connected to the second conductive contact. One of the first and second conductive posts has a insertion cavity formed on it, and the other conductive post can be inserted into the insertion cavity, with its outer wall forming a surface contact electrical signal connection with the cavity sidewall.

[0005] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: Since one of the first conductive post and the second conductive post has a plug-in cavity, the other conductive post can be inserted into the plug-in cavity and its outer side wall forms a surface contact electrical signal connection with the cavity side wall of the plug-in cavity. In this way, a stable electrical signal connection structure can be formed between the first conductive post and the second conductive post, which is beneficial to reducing the risk of unstable or failed electrical signal transmission during long-term use of the electronic lock, and also beneficial to reducing the fitting accuracy requirements between the first conductive post and the second conductive post in the length direction (axial direction).

[0006] Because of the above-mentioned features and advantages, this invention can be applied to electronic locks equipped with internal and external modules. Attached Figure Description

[0011] The structure of the electronic lock with internal and external modules, which applies the technical solution of the present invention, will be further described below with reference to the accompanying drawings. Except where explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or synergistic in function.

[0012] like Figure 1 and Figure 2 As shown, the present invention proposes an electronic lock configured with inner and outer modules, including a first module 100 and a second module 200 respectively installed on the inner and outer sides of a door leaf 300. The first module 100 includes a first outer shell 1 and a first circuit board 13 housed within the first outer shell 1. The second module 200 includes a second outer shell 2 and a second circuit board 23 housed within the second outer shell 2. The first module 100 further includes a first conductive contact 130 disposed on the first circuit board 13 and a first conductive post 5 electrically connected to the first conductive contact 130. The second module 200 further includes a second conductive contact 230 disposed on the second circuit board 23 and a second conductive post 6 electrically connected to the second conductive contact 230. One of the first conductive post 5 and the second conductive post 6 has a insertion cavity formed on it, and the other conductive post can be inserted into the insertion cavity, with its outer sidewall forming a surface contact electrical signal connection with the cavity sidewall.

[0013] In this embodiment, the first module 100 and the second module 200 are functional modules of the electronic lock. In this embodiment, the first module 100 is installed on the outer side of the door leaf 300, while the second module 200 is installed on the inner side of the door leaf 300. In other embodiments, it is also feasible to install the first module 100 on the inner side of the door leaf 300 and the second module 200 on the outer side of the door leaf 300.

[0014] In this embodiment, the first conductive contact 130 can be pressed together with the first conductive post 5 to form an electrical signal connection, or the first conductive contact 130 and the first conductive post 5 can be connected by an intermediate conductive element. The second conductive contact 230 and the second conductive post 6 can also adopt the above-described electrical signal connection structure. In this embodiment, both the first conductive contact 130 and the second conductive contact 230 are positive electrode contacts, and the negative electrode contacts on the first circuit board 13 and the second circuit board 23 can be connected by a plug-in electrical signal connection structure between the first conductive contact 130 and the second conductive contact 230.

[0015] In this embodiment, a connection cavity is formed on one of the first conductive post 5 and the second conductive post 6. This can be understood as the connection cavity being disposed on either the first conductive post 5 or the second conductive post 6. Figure 2 The first conductive post 5 (not marked, obscured by the first conductive post 5) is formed on the second conductive post 6. The first conductive post 5 is inserted into the insertion cavity of the second conductive post 6, and a surface contact electrical signal connection is formed between the outer wall of the first conductive post 5 and the side wall of the insertion cavity. The first conductive post 5 is a rigid metal conductive component. Compared with the soft conductive medium in the current patent 202022643641.2, the first conductive post 5 can be inserted into the insertion cavity more easily and conveniently, which is beneficial to improving installation efficiency. The insertion cavity of the second conductive post 6 extends axially and the cavity opening faces the first conductive post 5. In this way, after the first module 100 and the second module 200 are both installed on the door leaf 300, the first conductive post 5 can be easily inserted into the insertion cavity.

[0016] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: Since the first conductive post 5 and the second conductive post 6 form a surface contact electrical signal connection, a stable electrical signal connection structure can be formed between the first conductive post 5 and the second conductive post 6, which helps to reduce the risk of unstable or failed electrical signal transmission during long-term use of the electronic lock, and also helps to reduce the fitting accuracy requirements between the first conductive post 5 and the second conductive post 6 in the length direction (axial direction).

[0017] Furthermore, the first outer casing 1 includes a first casing base 11 and a first casing cover 12, the first circuit board 13 is mounted and fixed on the first casing cover 12 or the first casing base 11, and a first mounting hole is provided on the first casing base 11. Figure 2 (The part is obscured by the first insulating sleeve 4 and is not marked); it also includes the first insulating sleeve 4, which is hollow and thus has an inner cavity ( Figure 2(The first insulating sleeve 4 is not marked as it is obscured by the first conductive post 5). An outer edge 41 is formed on the first insulating sleeve 4. The outer diameter of the outer edge 41 is larger than the inner diameter of the first mounting hole. The first insulating sleeve 4 is inserted into the first mounting hole, and the outer edge 41 is restricted to the outside of the peripheral wall of the first mounting hole. An outer edge 51 is formed on the first conductive post 5. The outer diameter of the outer edge 51 is larger than the inner diameter of the inner cavity of the first insulating sleeve 4. The first conductive post 5 is fixed to the first circuit board 13. The first conductive post 5 is inserted into the first insulating sleeve 4, and the outer edge 51 is restricted to the outside of the outer edge 41. The outer edge 51 and the peripheral wall of the first mounting hole cooperate to restrict the axial position of the outer edge 41.

[0018] Among them, such as Figure 2 As shown, when the first module 100 and the second module 200 are respectively installed on the inner and outer sides of the door leaf 300, the first shell base 11 is closer to the second module 200 than the first shell cover 12.

[0019] The first circuit board 13 is mounted and fixed on the first shell cover 12 or the first shell base 11, so that the first circuit board 13 is stably positioned by means of the first shell cover 12 or the first shell base 11.

[0020] The first insulating sleeve 4 and the first shell base 11 are separate structures. When the first shell base 11 is a metal part, the first insulating sleeve 4 can be used to isolate the first conductive post 5 from the first shell base 11 to prevent the current flowing through the first conductive post 5 from being conducted to the first shell base 11 and causing leakage.

[0021] In this embodiment, the outer edge 41 of the insulating sleeve is confined to the outer side of the peripheral wall of the first mounting hole, and the outer edge 51 of the column is confined to the outer side of the outer edge 41 of the insulating sleeve. Thus, with the first conductive post 5 fixed to the first circuit board 13, the outer edge 41 of the insulating sleeve is clamped between the peripheral wall of the first mounting hole and the outer edge 51 of the column, thereby axially limiting the first insulating sleeve 4. In this embodiment, the first conductive post 5 is inserted into the first insulating sleeve 4 and also into the insertion cavity of the second conductive post 6.

[0022] Furthermore, it also includes a first conductive screw 14, which passes through the first circuit board 13 and is threadedly connected to the first conductive post 5. The first conductive screw 14 contacts and presses against the first conductive contact 130. In this way, the first conductive screw 14 not only serves as an intermediate conductive element between the first conductive contact 130 and the first conductive post 5, but also fixes the first conductive post 5 to the first circuit board 13.

[0023] Furthermore, it also includes a second conductive screw 24, which passes through the second circuit board 23 and is threadedly connected to the second conductive post 6. The second conductive screw 24 contacts and presses against the second conductive contact 230. In this way, the second conductive screw 24 can not only serve as an intermediate transmission device for electrical signals between the second conductive contact 230 and the second conductive post 6, but also fix the second conductive post 6 to the second circuit board 23.

[0024] Furthermore, the second outer shell 2 includes a second shell base 21 and a second shell cover 22. The second shell base 21 is a plastic part and is integrally formed with a second insulating sleeve 210. The second conductive post 6 is inserted into the second insulating sleeve 210. In this way, the second insulating sleeve 210 is used to prevent the current flowing through the second conductive post 6 from being conducted to the outside and causing leakage.

[0025] Furthermore, the system also includes a lock body (not shown in the figure), a transmission rod (not shown in the figure), and a drive motor (not shown in the figure) respectively mounted on the first module 100. The drive motor (not shown in the figure) is connected to the first circuit board 13 by a signal. The drive motor provides rotational driving force to the transmission rod. The lock body is provided with a latch for locking the door leaf 300. The transmission rod is connected to the latch. When the transmission rod is driven to rotate forward or backward by the drive motor, the transmission rod can drive the latch of the lock body to retract or extend, thereby opening or closing the door leaf 300. A controller (not shown in the figure) is provided on the first circuit board 13. When the controller receives an opening or closing indication signal, it can control the drive motor to drive the transmission rod to rotate forward or backward. The controller can also transmit control signals to the execution component provided on the second circuit board 23 through the plug-in connection between the first conductive post 5 and the second conductive post 6.

[0026] like Figure 3 and Figure 4As shown, a battery compartment 211 is provided inside the second outer casing 2. The battery compartment 211 can accommodate batteries, including a first battery 71, a second battery 72, and a third battery 73. The first battery 71, the second battery 72, and the third battery 73 are used to provide power to the second circuit board 23. The first battery 71 and the second battery 72 can be arranged longitudinally on the left and right sides of the second circuit board 23, and the third battery 73 can be arranged laterally on the front side of the second circuit board 23. In this way, by adopting the above-mentioned layout, the space inside the battery compartment 211 can be used efficiently, thereby allowing the battery compartment 211 to maintain a compact size. The second circuit board 23 is provided with a plug-in interface 231 for connecting to an external power source. In this way, when the battery is depleted, power can still be provided to the second circuit board 23 through the plug-in interface 231, and then power can be provided to the electrical components on the first module 100 through the plug-in electrical signal connection structure between the first circuit board 13 and the second circuit board 23.
