Description

Technical Field

[0001] The utility model relates to a smart lock motor steering detection structure. Background Art

[0002] At present, the door locks on the market have two opening directions: left-hand opening and right-hand opening. Different door opening directions correspond to different rotation directions of the door lock body. The rotation direction of the common smart door lock body on the market is fixed. During use, it is necessary to manually set the rotation direction or install the direction during the installation process. If the setting is wrong or the installation is wrong, the lock body will not rotate properly, which will cause the door to be unable to open and close normally. Setting this door opening direction or installing the door lock body requires a certain understanding of the door lock opening direction, which is easy to make mistakes, increasing the difficulty of users installing door locks and increasing the cost of after-sales installation support, which is not conducive to product promotion. Summary of the invention

[0003] In order to overcome the defects in the prior art, the utility model proposes a smart lock motor steering detection structure, and its specific technical solution is as follows:

[0004] A smart lock motor steering detection structure, characterized in that it includes a detection gear, a first optocoupler, a second optocoupler, a Hall switch, a magnet and an MCU module, the detection gear is driven by the smart lock motor, the detection gear is provided with a notch, the magnet is mounted on the detection gear, the first optocoupler and the second optocoupler are arranged circumferentially along the detection gear, the MCU module is electrically connected to the first optocoupler, the second optocoupler and the Hall switch, when the detection gear rotates, the Hall switch can be aligned with the magnet to trigger the Hall switch to generate a signal input to the MCU module, the first optocoupler and the second optocoupler are aligned with the notch in turn to trigger the first optocoupler and the second optocoupler to generate signals input to the MCU module.

[0005] Furthermore, the angle between the first optical coupler and the second optical coupler is 90°, and the line connecting the Hall switch and the first optical coupler passes through the center of the detection gear.

[0006] The beneficial effects of the utility model are:

[0007] Based on the corresponding mode, the MCU automatically learns and memorizes the door opening direction of the currently installed door lock by detecting the success or failure of the door opening direction. Compared with the door locks on the market, there is no need for manual judgment and setting of the opening direction of the currently installed door lock, eliminating the problem of abnormal unlocking caused by manual setting of unlocking errors, simplifying the usage method, and making the installation of the door lock more convenient and simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is the structural diagram of the smart lock motor steering detection. DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0010] See Figure 1 The utility model relates to a smart lock motor steering detection structure, including a detection gear 1, a first optical coupler 2, a second optical coupler 3, a Hall switch 4, a magnet 5 and an MCU module. The detection gear 1 is driven by the smart lock motor. The detection gear 1 is provided with a notch 11. The magnet 5 is mounted on the detection gear 1. The first optical coupler 2 and the second optical coupler 3 are arranged circumferentially along the detection gear 1. The MCU module is electrically connected to the first optical coupler 2, the second optical coupler 3 and the Hall switch 4. When the detection gear 1 rotates, the Hall switch 4 can be aligned with the magnet 5 to trigger the Hall switch 4 to generate a signal input to the MCU module. The first optical coupler 2 and the second optical coupler 3 are aligned with the notch 11 in sequence to trigger the first optical coupler 2 and the second optical coupler 3 to generate a signal input to the MCU module.

[0011] Furthermore, the angle between the first optical coupler 2 and the second optical coupler 3 is 90°, and the line between the Hall switch 4 and the first optical coupler 2 passes through the center of the detection gear 1 .

[0012] In actual applications, the MCU module will have a detection mode, the detection mode is:

[0013] When the detection gear 1 rotates forward, the first optocoupler 2 is not blocked by the detection gear 1 (i.e., it is opposite to the notch 11), and the first optocoupler 2 is triggered at this time; then the first optocoupler 2 is blocked by the detection gear 1, and the first optocoupler 2 is not touched at this time; the magnet 5 is not close to the Hall switch 4, and the Hall switch 4 is detected and is not triggered; the second optocoupler 3 is not blocked by the gear and is triggered; the second optocoupler 3 is blocked by the gear and is not touched, and the motor stops rotating and immediately rotates in the opposite direction; the first optocoupler 2 is not blocked by the detection gear, and the optocoupler 1 is triggered; the first optocoupler 2 is blocked by the detection gear, and the first optocoupler 2 is not touched at this time.

[0014] If the MCU module detects the above pattern when the motor is rotating, it means that the unlocking direction of the lock body is correct. If the above pattern cannot be detected during the rotation process and a stall is detected, it means that the unlocking direction is opposite to the rotation direction.

[0015] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
