Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and specifically discloses an intelligent door lock with a micro switch anti-disengagement structure and a micro switch anti-disengagement structure. Background Technique

[0002] As a highly sensitive mechanical and electrical component, the micro switch plays an important role in modern intelligent door locks. It is usually配合 with the lock tongue transmission component of the door lock to detect the telescopic state of the lock tongue and convert mechanical signals into electrical signals, so as to feedback the locked or unlocked state of the door lock to the control system. This function not only improves the intelligence level of the door lock, but also provides users with a convenient use experience, such as remote monitoring, automatic alarm, and linkage control with other smart home devices.

[0003] However, there are some problems in the installation and use of micro switches in the prior art. In the traditional door lock structure, the micro switch usually triggers the signal by contacting the transmission parts inside the door lock (usually in a sheet structure). This design has obvious defects: due to the high requirement for the matching accuracy between the micro switch and the transmission parts, once there is an error in the production or assembly process, or it is affected by collision and vibration during use, the micro switch is very likely to be misaligned horizontally. This misalignment will cause the micro switch to fail to trigger the signal normally, and then the control system of the door lock cannot accurately judge the telescopic state of the lock tongue, and finally the door lock fails. This phenomenon not only reduces the reliability of the door lock, but also may bring potential safety hazards to users. Especially in the intelligent door lock system that requires remote monitoring or automatic alarm, this problem is particularly prominent. Therefore, how to effectively prevent the horizontal misalignment and disengagement of the micro switch in the door lock has become an urgent technical problem to be solved. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an intelligent door lock with a micro switch anti-disengagement structure and a micro switch anti-disengagement structure.

[0005] On the one hand, the utility model discloses an intelligent door lock with a micro switch anti-disengagement structure, and adopts the following technical scheme:

[0006] An intelligent door lock with a micro switch anti-disengagement structure includes a housing and a lock tongue arranged in the housing. A driving motor assembly, a driving rotating block and a micro switch are arranged in the housing. The driving motor assembly drives the driving rotating block to rotate in the housing. The rotation of the driving rotating block drives the lock tongue to stretch and retract to realize the opening and closing of the door lock. The driving rotating block is equipped with an unlocking contact piece. The unlocking contact piece is provided with a limiting notch. Anti-disengagement gaskets are arranged on the front and back sides of the unlocking contact piece. The two anti-disengagement gaskets form a movable groove at the limiting notch. At least part of the micro switch moves relative to each other in the movable groove.

[0007] Preferably, the unlocking contact piece is provided with a first mounting hole, the anti-detachment pad is provided with a second mounting hole corresponding to the first mounting hole, the driving block is provided with a mounting post for insertion into the first mounting hole and the second mounting hole, the mounting post is provided with a placement protrusion, and the unlocking contact piece and the anti-detachment pad are placed on the placement protrusion.

[0008] Preferably, the drive rotating block is provided with a first limiting block, and the unlocking contact piece is provided with a first limiting groove that engages with the first limiting block; the drive rotating block is provided with a second limiting protrusion, and the anti-detachment pad is provided with a second limiting groove that engages with the second limiting protrusion.

[0009] Preferably, the first limiting groove and the second limiting groove overlap in the axial projected area, and the first limiting block and the second limiting block are integrally disposed on the drive rotating block.

[0010] Preferably, the first limiting groove is connected to the first mounting hole, the second limiting groove is connected to the second mounting hole, and the first limiting block and the second limiting block are integrally disposed on one side of the mounting post of the drive rotating block.

[0011] Preferably, the two edges of the limiting notch are provided with guide slopes.

[0012] Preferably, the micro switch includes a housing and a drive element disposed on the housing, the end of the drive element extending into the movable groove.

[0013] On the other hand, this utility model discloses a micro switch anti-disengagement structure, which includes the aforementioned drive rotating block, unlocking contact piece, and anti-disengagement pad.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention features a microswitch anti-disengagement structure, including an unlocking contact piece and an anti-disengagement pad, which limits the microswitch to the movable groove formed by the unlocking contact piece and the anti-disengagement pad. This avoids the problem of lateral misalignment between the microswitch and the unlocking contact piece caused by production or assembly errors or by impacts and vibrations, thus improving the operational reliability and service life of the smart lock. Furthermore, compared to a one-piece molded design with a groove, this solution utilizes a split structure to assemble the movable groove, resulting in lower production costs and a thinner structure.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This embodiment discloses a smart door lock with microswitch anti-disengagement mechanism and a microswitch anti-disengagement structure for the smart door lock. (Refer to...) Figure 1 The smart door lock includes a housing 1 and a latch 2 disposed within the housing 1. The housing 1 contains a circuit board 3, a drive motor assembly 4, a drive rotor 6, and a micro switch 5. The micro switch 5 is electrically connected to the drive motor assembly 4 and the circuit board 3. The drive motor assembly 4 drives the drive rotor 6 to rotate within the housing 1. Specifically, the drive rotor 6 is driven to rotate via a gear set connected to the drive motor assembly 4. The drive rotor 6 has a swing arm, and the latch 2 has a locking hook that cooperates with the swing arm, thereby causing the drive rotor 6 to rotate and drive the latch 2 to extend and retract, thus opening and closing the door lock. Since the drive structure of the latch 2 is not an improvement in this solution, except for the embodiment attached... Figure 1 In addition to the transmission structure shown, other locking tongue transmission structures can also be used.

[0023] Among them, reference Figure 2-3 The drive block 6 is equipped with an unlocking contact piece 7, which has a limiting notch 73. Each side of the unlocking contact piece 7 has an anti-detachment pad 8, and the two anti-detachment pads 8 form an arc-shaped movable groove 83 at the limiting notch 73. The micro switch 5 moves relatively within the movable groove 83, at least partially. Specifically, the micro switch 5 includes a housing and a drive element mounted on the housing. The drive element, as the external operating component of the micro switch 5, receives external force or displacement signals and transmits them to the internal actuating spring. The end of the drive element extends into the movable groove 83. The limiting notch 73 preferably has guide ramps 74 on both sides along the rotation direction of the drive block 6, so that the drive element of the micro switch 5 is better triggered by contacting the guide ramps 74 of the limiting notch 73.

[0024] When the drive motor assembly 4 starts and drives the drive rotor 6 to rotate, the micro switch 5 moves relative to the movable groove 83 formed between the unlocking contact piece 7 and the two anti-disengagement pads 8. When the micro switch 5 touches the inner wall of the edge of the movable groove 83, the bolt 2 is driven to the unlocking or locking state by the drive rotor 6. The micro switch 5 converts the mechanical signal into an electrical signal due to being touched, and feeds back the lock or unlocking status of the door lock to the control system of the circuit board 3. By setting the anti-disengagement structure of the two anti-disengagement pads 8 on the front and back of the unlocking contact piece 7, the micro switch 5 can be limited between the movable grooves 83. Unlike the traditional micro switch triggering structure, the anti-disengagement structure of this solution avoids the problem of lateral misalignment between the micro switch 5 drive element and the unlocking contact piece 7 caused by production or assembly errors or collisions and vibrations, thus improving the operational reliability and service life of the smart door lock.

[0025] Furthermore, in this embodiment, the unlocking contact piece 7 is provided with a first mounting hole 71, the anti-detachment pad 8 is provided with a second mounting hole 81 corresponding to the first mounting hole 71, and the driving rotating block 6 is provided with a mounting post 61 for insertion into the first mounting hole 71 and the second mounting hole 81. The mounting post 61 is provided with a placement protrusion 62, and the unlocking contact piece 7 and the anti-detachment pad 8 are placed on the placement protrusion 62. In addition, the driving rotating block 6 is provided with a first limiting block 63, and the unlocking contact piece 7 is provided with a first limiting groove 72 that engages with the first limiting block 63; the driving rotating block 6 is provided with a second limiting protrusion 63, and the anti-detachment pad 8 is provided with a second limiting groove 82 that engages with the second limiting protrusion 63. By adopting the above design, the assembly efficiency of the unlocking contact piece 7 and the anti-detachment pad 8 is higher, and the installation stability is better. Preferably, the first limiting groove 72 and the second limiting groove 82 overlap in the axial projected area. The first limiting groove 72 communicates with the first mounting hole 71, and the second limiting groove 82 communicates with the second mounting hole 81. The first limiting block 63 and the second limiting block 63 are integrally disposed on one side of the mounting post 61 of the drive rotating block 6. This simplifies the structure of the drive rotating block and facilitates assembly.
