Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and in particular to an intelligent lock that does not require a mechanical key. Background Art

[0002] Smart locks are different from traditional mechanical locks and are more intelligent in terms of user identification, security, and management. They are the actuators for locking doors in access control systems. Mechanical combination locks are fully mechanical combination locks with no electronic components, a large number of keys, and high reliability.

[0003] Existing smart locks include fingerprint unlocking, portrait unlocking, etc. When the smart unlocking function cannot be realized normally, emergency unlocking is performed through a mechanical key to open the door. The existing application number is: CN202221480103.9, and the patent name is "A new type of mechanical password door lock structure" Chinese patent, which discloses "A new type of mechanical password door lock structure, including a front door lock (1) and a rear door lock (2), characterized in that: the upper ends of both sides of the front door lock (1) are fixedly provided with a slide groove (3), the upper front end of the front door lock (1) is slidably provided with a slide plate (4), and the upper front end of the front door lock (1) is fixedly provided with a password button (7), A slot body (12) is fixedly provided below the front end of the front door lock (1), a plurality of magnets (14) are fixedly provided at the front end of the front door lock (1) and outside the slot body (12), a sealing cover (16) is rotatably provided at the lower end of the front door lock (1) via a rotating shaft (15), and a plurality of mechanical code wheels (13) are rotatably provided in the slot body (12). The door lock can be unlocked by the mechanical code wheel, avoiding the use of a mechanical key for unlocking, but the operation of the six mechanical code wheels is relatively complicated. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a smart lock that can be unlocked in an emergency and does not require a mechanical key.

[0005] In response to the above problems, the following technical solutions are provided: a smart lock that does not require a mechanical key, comprising a shell, a button lock assembly installed in the shell, a motor clutch that controls the opening and closing of the smart lock tongue, a handle assembly that drives and cooperates with the motor clutch, a mechanical password lock located in the shell, and a panel that matches the shell, the panel being provided with an opening slot corresponding to the mechanical password lock, a lock cover being installed at the notch of the opening slot, the mechanical password lock comprising a mounting bracket installed in the shell, a mechanical password wheel connected to the mounting bracket, and a reset button for modifying the password of the mechanical password wheel, the mechanical password wheel being provided with four, the mounting bracket being slidably connected to a push plate that moves back and forth toward the motor clutch, the push plate being locked and unlocked by the mechanical password wheel to achieve the fixation or position of the push plate The cam is provided with a plurality of locking plates, each of which is provided with a plurality of locking plates, and the plurality of locking plates are provided with a plurality of locking plates.

[0006] In the above structure, the fingerprint recognition component is installed in the handle of the handle assembly. When fingerprint unlocking and password unlocking cannot be achieved, the four mechanical password wheels can be rotated to the correct password, which drives the push switch to cause the push plate to move upward. The push plate pushes the push rod upward, and the push rod pushes the transmission rod to move until the unlocking pin is pushed into the bayonet. The handle is rotated, and the handle drives the fixed plate to rotate. The rotating wheel is linked to the fixed plate through the unlocking pin, thereby achieving the displacement of the smart lock tongue to unlock and open the door. After opening the door, the handle is reset, the push switch is controlled to move downward and reset, the transmission rod, push rod and unlocking pin are all reset, and the mechanical password wheel is rotated to scramble them. The mechanical password wheel can be used for emergency use when fingerprint unlocking and password unlocking fail. The provision of four mechanical password wheels makes it easier for users to operate, improving the convenience of unlocking operation of the utility model. When the correct password is entered through the mechanical password wheel, the password can be changed by pressing the reset button, thereby improving the security of the utility model. By providing the bayonet, the fixing piece can be facilitated to drive the rotating wheel to rotate through the unlocking pin to achieve unlocking, thereby improving the reliability of the utility model.

[0007] The utility model is further configured such that a mounting block is provided in the radial direction of the rotating wheel, a mounting hole for installing an unlocking pin is provided on the mounting block, a limiting hole with a diameter smaller than the mounting hole is provided on one end of the mounting hole facing the transmission shaft, a positioning column passing through the limiting hole is provided at one end of the unlocking pin, and a reset spring located in the mounting hole is sleeved on the positioning column.

[0008] In the above structure, the installation of the mounting block facilitates the installation of the unlocking pin and facilitates the fixing plate to drive the rotating wheel to rotate via the unlocking pin, thereby unlocking the door lock. The provision of a limiting hole facilitates the displacement of the positioning post on the unlocking pin into the bayonet, and prevents the unlocking pin from entering the bayonet as a whole, thereby improving the reliability of the present invention. The provision of a reset spring facilitates the reset of the unlocking pin, and the unlocking pin can push the transmission rod and push rod to reset the door lock, thereby improving the safety and reliability of the present invention and preventing the positioning post from being retained in the bayonet, allowing the door lock to be unlocked by turning the handle, thereby causing the door lock to fail.

[0009] The present invention is further configured such that the unlocking pin is configured with a rounded corner at one end of the transmission rod.

[0010] The above structure can avoid significant wear between the unlocking pin and the transmission rod, thereby extending the service life of both.

[0011] The present invention is further configured such that an arc-shaped limiting plate is provided at one end of the transmission rod facing the unlocking pin.

[0012] By adopting the above structure, the unlocking pin can be limited by the arc-shaped limiting plate, preventing the unlocking pin from popping out when the fixing plate drives the rotating wheel to rotate through the unlocking pin, thereby improving the stability of the unlocking pin and further improving the reliability of the utility model.

[0013] The present invention is further configured such that a limiting groove for accommodating an arc-shaped limiting plate is provided on the motor housing.

[0014] In the above structure, the arc-shaped limiting plate can be limited by providing the limiting groove, thereby improving the stability of its displacement and enhancing the reliability of the utility model.

[0015] The present invention is further configured such that an abutment plate is provided at one end of the push rod facing the push plate.

[0016] In the above structure, the contact area between the push rod and the push plate can be increased by providing the abutment plate, thereby facilitating the push plate to push the push rod and improving the user's comfort when controlling the push plate to push the push rod to move by pushing the switch.
