Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an operating mechanism for closing a door lock in its normally open mode. Background Technology

[0002] A door lock is a locking device used to lock a door to prevent others from opening it. Most existing door locks are intelligent electric door locks. When an electric door lock is installed on a door, it can drive a motor to move the hook or bolt according to the signal received by the control circuit, so as to open or lock the door.

[0003] Current smart locks unlock by inputting the correct command (password, fingerprint, etc.) to control a motor-driven push plate, which moves a pin to unlock the door. The motor then automatically resets after 3 seconds or a factory-set number of seconds, preventing the outside handle from turning and thus requiring a different command each time. This is cumbersome. Therefore, a normally open mode is needed. In this mode, no command is required from either the inside or outside; simply turning the handle unlocks the door. However, to close the normally open mode (which requires a different command to enter), the user must use a fingerprint, password, or other input method. This is inconvenient and cumbersome. In existing locks, the motor-driven push plate pushes a pin into a transmission head, keeping the outside handle linked to the transmission head, allowing unlocking without a command. To close the normally open mode, the user must again input the correct command (password, fingerprint, etc.), which is also inconvenient. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an operating mechanism that makes it easier for users to close the door lock in the always-open mode.

[0005] To address the above issues, the following technical solution is provided: an operating mechanism for closing the normally open mode of a door lock, installed inside the inner door lock body, including an inner door handle and a handle head connected to the inner door handle. The handle head includes a base located inside the inner door lock body and a connecting post protruding from the inner door lock body and connected to the handle. It also includes a sensing component, which includes a circuit board installed inside the inner door lock body, a Hall sensor connected to the circuit board, and a magnet installed on the base. The magnet is located at the position where the handle rotates in the opposite direction to the door opening direction.

[0006] In the above structure, the drive motor controlling the locking and unlocking of the door lock is electrically connected to the circuit board. When the user needs to close the normally open mode, lifting the inner door handle rotates the handle head, causing the handle head to rotate the magnet to correspond with the Hall sensor. This causes the Hall sensor to send a signal to the drive motor, which then controls the push plate to reset, resetting the pin shaft. This prevents the outer door handle from being directly rotated to unlock the door, thus closing the normally open mode. Closing the normally open mode by lifting the inner door handle facilitates user operation and improves the ease of use of this invention.

[0007] The present invention is further configured such that a limiting tube is provided in the inner door lock body in the axial direction relative to the handle head, a positioning block is provided on both sides of the limiting tube in the inner door lock body, a reset torsion spring is sleeved on the outside of the limiting tube, a limiting post is provided at one end of the base facing the connecting post, and the two ends of the reset torsion spring abut against the positioning blocks on both sides of the limiting tube and the upper side of the limiting post, respectively.

[0008] In the above structure, the inclusion of a reset torsion spring improves the user's feel when lifting the inner handle and facilitates the reset of the inner door handle, handle head, and magnet, thereby enhancing the reliability of this invention. The positioning block and limiting tube facilitate the positioning and installation of the reset torsion spring, improving the ease of installation and the reliability of force application. The positioning post facilitates the engagement and reset of the handle head with the reset torsion spring, enabling reset.

[0009] The present invention is further provided that a connecting hole is provided on the base at a position symmetrical to the connecting column in the axial direction opposite to the limiting column. The connecting hole is used to connect a screw, and the screw abuts against one end of the reset torsion spring.

[0010] In the above structure, connecting the screw into the connecting hole further facilitates the engagement of the handle with the torsion spring, thereby improving the reliability of this utility model.

[0011] The present invention is further provided that the base has a lug protruding outward from the limiting post and the connecting hole.

[0012] The above structure facilitates the cooperation of the limiting post, screw and reset torsion spring, and reduces the starting torque of lifting the inner door handle, thus making it easier for the user to operate.

[0013] The present invention is further provided that a fixing block is provided at one end of the base opposite to the connecting column, and a fixing groove for fixing the magnet is provided on the fixing block.

[0014] In the above structure, the fixing block facilitates the corresponding cooperation between the magnet and the Hall sensor, and the fixing groove improves the convenience and firmness of magnet installation, thereby improving the reliability of this utility model.

[0015] The present invention is further configured such that two magnets are symmetrically arranged relative to the central axis of the connecting column.

[0016] With the above structure, the limiting post and screw can be used together to allow the inner door handle to still close the normally open mode by lifting the handle after the direction is reversed. This makes it easy for this utility model to adjust the direction of the inner door handle according to the user's needs. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] like Figures 1 to 7 The illustrated operating mechanism for closing the normally open mode of a door lock is installed inside the inner door lock body 1. It includes an inner door handle 2 and a handle head 3 connected to the inner door handle 2. The handle head 3 includes a base 31 located inside the inner door lock body 1 and a connecting post 32 protruding from the inner door lock body 1 and connected to the handle. It also includes a sensing component 4. The sensing component 4 includes a circuit board 41 installed inside the inner door lock body 1, a Hall sensor 42 connected to the circuit board 41, and a magnet 43 installed on the base 31. The magnet 43 is located in the opposite rotation position of the handle relative to the door opening direction.

[0028] In the above structure, the drive motor 01, which controls the locking and unlocking of the door lock, is electrically connected to the circuit board 41. When the user needs to close the normally open mode, by lifting the inner door handle 2, the handle head 3 is rotated. The handle head 3 drives the magnet 43 to rotate until it corresponds to the Hall sensor 42. This causes the Hall sensor 42 to send a signal to the drive motor 01, which then controls the push plate 02 to reset, and the pin 03 to reset. This prevents the outer door handle from being directly rotated to unlock the door, thus closing the normally open mode. Closing the normally open mode by lifting the inner door handle 2 facilitates user operation and improves the ease of use of this invention.

[0029] In this embodiment, a limiting tube 11 is provided inside the inner door lock body 1 in the axial direction relative to the handle head 3. Positioning blocks 12 are provided on both sides of the limiting tube 11 inside the inner door lock body 1. A reset torsion spring 5 is sleeved on the outside of the limiting tube 11. A limiting post 311 is provided on one end of the base 31 facing the connecting post 32. The two ends of the reset torsion spring 5 abut against the upper side of the positioning blocks 12 on both sides of the limiting tube 11 and the limiting post 311, respectively.

[0030] In the above structure, the reset torsion spring 5 improves the user's feel when lifting the inner handle and facilitates the reset of the inner door handle 2, handle head 3, and magnet 43, thereby enhancing the reliability of this invention. The positioning block 12 and limiting tube 11 facilitate the positioning and installation of the reset torsion spring 5, improving the ease of installation and the reliability of its force application. The positioning post facilitates the engagement and reset of the handle head 3 with the reset torsion spring 5, enabling reset.

[0031] In this embodiment, a connecting hole 312 is provided on the base 31 at a position symmetrical to the connecting post 32 in the axial direction of the limiting post 311. The connecting hole 312 is used to connect a screw, and the screw abuts against one end of the reset torsion spring 5.

[0032] In the above structure, connecting the screw into the connecting hole 312 further facilitates the engagement of the handle 3 with the torsion spring, thereby improving the reliability of this utility model.

[0033] In this embodiment, the base 31 has a lug 313 protruding outward from the limiting post 311 and the connecting hole 312.

[0034] The above structure facilitates the cooperation between the limiting post 311, the screw and the reset torsion spring 5, and reduces the starting torque of lifting the inner door handle 2, thereby making it easier for the user to operate.

[0035] In this embodiment, a fixing block 314 is provided on one end of the base 31 opposite to the connecting column 32, and a fixing groove 315 for fixing the magnet 43 is provided on the fixing block 314.

[0036] In the above structure, the fixing block 314 facilitates the corresponding cooperation between the magnet 43 and the Hall sensor 42, and the fixing groove 315 improves the convenience and firmness of the installation of the magnet 43, thereby improving the reliability of this utility model.

[0037] In this embodiment, there are two magnets 43 arranged symmetrically with respect to the central axis of the connecting post 32.

[0038] With the above structure, the limiting post 311 and screw can be used together so that the inner door handle 2 can still be closed in the normally open mode by lifting the handle after the direction is reversed. This makes it easy for the present invention to adjust the direction of the inner door handle 2 according to the user's needs.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
