Description

Technical Field

[0001] The utility model relates to the technical field of smart home door locks, in particular to a smart home door lock. Background Art

[0002] The smart home door lock based on dynamic password disclosed by publication number CN206987571U has a built-in dynamic password generator, the password generator is connected to the mobile terminal through a network signal, a password input keyboard and a display screen are arranged on the housing of the smart home door lock, and the smart home door lock also has a built-in power-on module, the power-on module is provided with a relay, and the relay is electrically connected to the lock core switch device.

[0003] The lock core switch device of its smart home door lock is equipped with a coil, which is connected to a relay. After the password is entered, the relay turns on the circuit, which in turn energizes the coil, generates a magnetic field, and generates a reaction force on the magnet, causing the magnet to move backwards. The magnet drives the entire lock core switch device to move backwards, and the lock head retracts backwards, so that the door can be opened. After a period of time, when the relay is powered on, the relay is disconnected, the coil is not energized, and no magnetic field is generated. The spring pushes the entire lock core switch device forward.

[0004] The technical solution in this comparative document has the effect of opening and closing the door lock using a dynamic password, but the defects it brings are also more obvious. For example, when the lock core switch device is driven to move by the electromagnetic coil, the lock pin moves too fast and hits the door frame lock slot when closing the door, which will generate a lot of noise and affect the user's experience. This solution has a poor silent effect on closing the smart door lock. Utility Model Content

[0010] In a specific embodiment, a sliding bar is axially symmetrically arranged on the side of the smart door lock, and a groove is formed on the side of the sliding bar.

[0011] In a specific embodiment, a side surface of the slide bar is slidably connected to a slide column via a groove, and a dust cover is fixedly connected to the side surface of the slide column, and a trigger switch is provided on the side surface of the dust cover.

[0012] In a specific embodiment, a handle is fixedly connected to the side of the smart door lock, and a protrusion for easy identification is provided on the side of the handle.

[0013] Compared with the prior art, the utility model provides a smart home door lock, which has the following beneficial effects:

[0014] In the technical solution disclosed by the utility model, when the door is closed, the smart door lock controls the internal driving motor to start working, driving the gear at one end of the screw rod to move, and the gear drives the lock pin fixed above the movable plate. The lock pin moves slowly, which can effectively reduce the noise when the lock pin hits the lock slot of the door frame.

[0015] Through the moving assembly provided by the utility model, the driving motor drives the screw rod to move inside the frame. When the splint fixed on the side of the bearing at one end of the screw rod moves inside the frame, the gear inside the splint moves on the surface of the meshing tooth plate, and at the same time drives the moving plate meshing on the top surface to move on the sliding mouth of the top surface of the frame. The three locking pins fixed on the top surface of the moving plate move and enter the lock groove of the door frame, thereby effectively reducing the noise generated by the lock pin entering the lock groove of the door frame and improving the customer experience.

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figure 1-Figure 4 An embodiment of the utility model is a smart home door lock, including a smart door lock 1, a slide groove is opened inside the smart door lock 1, and a slidable slider 2 is arranged inside the slide groove, a driving motor 3 is installed on the top surface of the slider 2, and a moving component 4 is arranged at one end of the driving motor 3, three lock pins 6 connected by a connecting rod 5 are arranged on the top surface of the moving component 4, and an energy-saving structure 7 is arranged on the side of the smart door lock 1.

[0024] The specific problem addressed by this specific embodiment is to solve the problem that when the electromagnetic coil drives the lock core switch device to move, the movement speed of the lock pin 6 is too fast. When closing the door, the lock pin 6 hits the door frame lock slot, which will generate a lot of noise, affecting the user's experience. This solution has a poor silent effect on the closing of the smart door lock 1. The utility model uses the smart door lock 1 to control the internal drive motor 3 to start working when closing the door, and drives the gear 44 at one end of the screw rod 41 to move. The gear 44 drives the lock pin 6 fixed above the moving plate 46. The lock pin 6 moves slowly, which can effectively reduce the noise when the lock pin 6 hits the door frame lock slot.

[0025] The moving component 4 includes a screw rod 41 fixedly connected to the output end of the driving motor 3, and one end of the screw rod 41 is installed with a clamping plate 43 through a sleeve bearing 42, a rotatable gear 44 is arranged inside the clamping plate 43, the bottom surface of the gear 44 is meshed with a tooth plate 45, and the top surface is meshed with a moving plate 46. In the present specific embodiment, the tooth plate 45 is fixed to the inner bottom wall of the frame 8, the top surface of the frame 8 is provided with a sliding opening, and the sliding opening is matched with the moving plate 46, and the side of the frame 8 is provided with a screw hole that is matched with the screw rod 41. The driving motor 3 drives the screw rod 41 to move inside the frame 8. When the splint 43 fixed on the side of the bearing 42 at one end of the screw rod 41 moves inside the frame 8, the gear 44 inside the splint 43 moves on the surface of the meshing tooth plate 45, and at the same time drives the movable plate 46 meshing on the top surface to move on the sliding mouth of the top surface of the frame 8. The three locking pins 6 fixed on the top surface of the movable plate 46 move and enter the lock groove of the door frame, thereby effectively reducing the noise generated by the lock pin 6 entering the lock groove of the door frame and improving the customer experience.

[0026] In this specific embodiment, the energy-saving structure 7 includes a top plate 71 arranged on the side of the smart door lock 1, and an LED light strip 72 is arranged on the bottom surface of the top plate 71, a placement groove is opened on the side of the smart door lock 1, and a light sensor 73 is arranged inside the placement groove, and a dust-proof light-transmitting plate 74 is arranged on the side of the placement groove;

[0027] Through the setting of the energy-saving structure 7, when the door is opened at night, the dust cover 9 is lifted, and the switch 11 is triggered so that the LED light strip 72 is connected to the power supply and starts working, illuminating the buttons on the side of the smart door lock 1. At the same time, when the dust cover 9 is closed, the LED light strip 72 is turned off, and the light sensor 73 detects the brightness change, and controls the smart door lock 1 to cut off the power, which improves the energy saving performance of the smart door lock 1 and increases the standby service life.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
