[0002] Currently, electronic smart door locks are becoming more and more widely used, and users are increasingly demanding information about the lock and door opening and closing status. Existing door lock detection methods include main lock tongue status detection, safety tongue status detection, and tilt lock tongue detection.

[0003] Existing latch locks have the following drawbacks: the bolt detection device can only determine whether the bolt is extended or retracted, but cannot accurately reflect the bolt's specific position; and if the power is suddenly lost in the closed or open state, the electronically controlled lock must be reset to operate normally. To address these issues, a motor-driven bolt can be used, but stepper motors are relatively expensive.

[0004] In addition, since latch locks are generally installed on door frames, the installation environment has high requirements on the vertical dimensions of the lock; once the latch lock is thicker, it not only affects the appearance, but also requires a larger installation slot during installation.

[0024] like Figure 1 Shown is a diagram of a flat electric bolt lock in a normal state according to an embodiment of the present invention; Figure 2 and Figure 3 .

[0025] The flat electric deadbolt lock of this embodiment includes: a base 1, a controller, a motor 2, a horizontal rack 4 and a vertical rack 3; the motor 2 is fixedly mounted on the base 1, and the motor 2 has a rotating shaft 20, on which two drive gears are mounted; the base 1 is generally a steel flat plate and serves as the outer shell of the deadbolt lock.

[0026] The motor 2 is used to drive the lock pin 3 to complete the specified action of the lock; generally, a planetary gear reducer 21 is provided at one end of the motor 2, and the motor 2 is connected to the rotating shaft 20 through the planetary gear reducer 21.

[0027] The base 1 is also provided with a lock pin 30 that can slide up and down, and the vertical rack 3 is fixed on the lock pin 30; Figure 3 The base 1 is also provided with a horizontally slidable slide 40, and the transverse rack 4 is fixed on the slide 40; the two driving gears are respectively engaged with the transverse rack 4 and the vertical rack 3; the base 1 is provided with a position sensor 6, and the position sensor 6 is located in the sliding direction of the slide 40.

[0028] Specifically, the two driving gears are respectively a first driving gear 23 and a second driving gear 24 ; the first driving gear 23 is engaged with the vertical rack 3 , and the second driving gear 24 is engaged with the horizontal rack 4 .

[0029] The motor 2 drives the rotating shaft 20 to rotate, so that the driving gear drives the locking pin 30 to slide through the vertical rack 3, and at the same time, the driving gear drives the sliding seat 40 to slide through the horizontal rack 4.

[0030] During actual use, since the first drive gear 23 and the second drive gear 24 are both fixed on the rotating shaft 20, the rotation of the rotating shaft can synchronously drive the vertical rack 3 to slide up and down, and at the same time make the horizontal rack 4 slide back and forth; the sliding state and position of the two are synchronized, and the position of the slide 40 on the horizontal rack 4 can be detected to determine the position state of the locking pin 30.

[0031] The position sensor 6 and the motor 2 are electrically connected to the controller respectively;

[0032] Typically, this embodiment further includes: a circuit board; a controller integrated on the circuit board, the controller being generally a programmable controller, a single chip microcomputer or a logic control circuit;

[0033] The position sensor 6 generally includes: a proximity switch, a photoelectric switch or a Hall effect sensor.

[0034] Generally, the position sensor 6 of this embodiment consists of two parts: one part, mounted on the slide 40, generates a magnetic field of constant strength; the other part, mounted on the base 1, detects the position of the slide by sensing changes in the magnetic field. Both the position sensor 6 and the motor 2 are electrically connected to the controller, enabling the controller to detect the position of the lock pin 30 through the position sensor.

[0035] Furthermore, a micro switch 5 is provided on the base 1; the micro switch 5 is located at one end of the sliding direction of the slide 40 and corresponds to the slide 40. The micro switch 5 is used to send an electrical signal to the controller when the slide 40 moves to the limit state, so as to complete the unlocking or locking state, thereby putting the device into standby mode or low power mode.

[0036] In an embodiment of the present invention, a rotating shaft on a motor drives two racks in different directions to slide synchronously, thereby achieving control of the opening and closing of the lock pin in the vertical direction, and at the same time being able to determine the position of the lock pin at all times through the horizontal displacement of the horizontal rack, thereby achieving feedback of the electronic control state.

[0041] The two slots are equivalent to sliding rails, through which the slide 40 slides relative to the base 1 .

[0042] In the flat electric bolt lock of this embodiment, a first support plate 11 is provided on the base 1. The first support plate 11 has a shaft hole. The motor 2 is mounted on the first support plate 11, and the rotating shaft 20 passes through the shaft hole. The first support plate 11 is vertically fixed to the base.

[0043] Preferably, a second support plate 12 is further provided on the base 1; the second support plate 12 is parallel to the first support plate 11, and the second support plate 12 and the first support plate 11 are respectively located at both ends of the rotating shaft 20, thereby maximally ensuring that the rotating shaft 20 is not prone to radial deformation during rotation, and can ensure long-term stable operation of the equipment; the second support plate 12 has a shaft sleeve, and one end of the rotating shaft 20 passes through the shaft sleeve and is connected to the second support plate 12.

[0044] In addition, the flat electric bolt lock of the present invention has low production cost, is small and exquisite, has a compact structural design, stable finished product quality, is beautiful and elegant, is easy to operate and maintain, and is suitable for various modified electric controlled bolt locks.
