Description

Technical Field

[0001] This invention relates to the field of smart home technology, and in particular to a smart door and window electronic lock with location monitoring and a door / window. Background Technology

[0002] The opening angle and opening method of doors and windows equipped with electronic locks are often achieved by changing the position of the handle. When the handle is in different set positions, the door and window are in the corresponding state.

[0003] However, most existing electronic locks control the handle position using a single-point or multi-point method. When the lock cylinder rotates to a specific position, it triggers a limit switch, which then controls the motor's power supply based on the limit switch signal, locking the door or window. During this process, it's impossible to monitor the electronic lock's position in real time, nor can it determine whether the handle is in the preset position.

[0004] Therefore, those skilled in the art urgently need to research an electronic lock that can monitor the handle position in real time and adjust the handle position according to a preset position. Summary of the Invention

[0005] The purpose of this invention is to address the technical problems existing in the background art by proposing an electronic lock that can monitor the handle position in real time and adjust the handle position according to a preset position.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A smart door and window electronic lock with location monitoring, comprising: The handle allows you to control the state of doors and windows by rotating it. The lock body includes a housing with a certain volume and a guide plate disposed on one side of the housing. A first rack and a second rack are spaced apart on the guide plate, and the first rack and the second rack are movable relative to the guide plate. The lock body also includes a transmission system, a circuit board with a control system, a power source, and an angle sensor. The transmission system includes a transmission gear set, a connecting gear set, an output gear set, and an adjusting gear set. The connecting gear set meshes with the first rack, the adjusting gear set meshes with the second rack, and the connecting gear set also meshes with the output gear set and the motor transmission gear set. The angle sensor and the circuit board are connected to the adjusting gear set, which can drive the angle sensor to rotate. The power source drives the gear set to rotate, and the rotating gear set drives the output gear set to rotate and moves the first rack and the second rack. The second rack drives the adjustment gear set to rotate, and the angle sensor rotates accordingly. The control system in the circuit board converts the resistance value of the angle sensor into the corresponding angle of the output gear set.

[0007] In one embodiment, the outer ends of the first rack and the second rack are respectively provided with limit structures.

[0008] In one embodiment, the output gear set is provided with a connecting hole, and one end of the handle is disposed in the connecting hole and can rotate together with the connecting hole.

[0009] In one embodiment, the connecting hole is a square hole.

[0010] In one embodiment, a gear rotating shaft is provided on one gear of the adjusting gear set, and a central hole is provided on the angle sensor, with the rotating shaft cooperating with the central hole.

[0011] In one embodiment, both sides of the gear on which the rotating shaft is provided are flat.

[0012] In one embodiment, the circuit board is provided with a through hole for the gear rotation shaft to pass through.

[0013] In one embodiment, the circuit board is disposed between the adjusting gear set and the angle sensor.

[0014] Another object of the present invention is to provide a door or window having the above-mentioned intelligent electronic lock.

[0015] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: The structural design of this invention, through the linkage between the transmission system and the rack, converts the linear motion of the transmission system into the linear motion of the rack, and converts the handle position into the resistance value of the angle sensor 9, and linearizes the resistance value of the angle sensor 9, thus achieving the purpose of real-time monitoring of the handle position. When opening and closing windows, if the door or window handle is not in the set position, the smart door and window electronic lock with position monitoring will automatically adjust to the correct position, allowing the handle position to be adjusted according to the preset position, further improving the flexibility and security of the smart door and window electronic lock with position monitoring.

[0016] Since the rotation of the angle sensor is driven by the second rack, the rotation process is not subject to compression by the transmission system, which extends the service life of the angle sensor and improves the economic efficiency of the electronic lock. Attached Figure Description

[0023] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described herein are merely exemplary. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, this invention provides an intelligent electronic lock for doors and windows with location monitoring, such as... Figure 1 As shown, this type of smart door and window electronic lock with position monitoring includes a handle A and a lock body B. The handle A controls the state of the door and window by rotation, such as whether the door and window are open or closed, and the size of the opening.

[0026] The lock body B includes a housing 2 with a certain volume and a guide plate 10 disposed on one side of the housing 2. A first rack 11 and a second rack 12 are spaced apart on the guide plate 10, and the first rack 11 and the second rack 12 can move relative to the guide plate 10. When in use, the housing 2 of the lock body B is also provided with a top cover.

[0027] like Figure 2 and Figure 3As shown, lock body B also includes a transmission system, a circuit board 5 with a control system, a motor used as a power source, and an angle sensor 9. The transmission system includes a speed-changing gear set 4, a connecting gear set 8, an output gear set 3, and an adjusting gear set, namely a gear set composed of gear 6 and gear 7.

[0028] The connecting gear set 8 meshes with the first rack 11, the adjusting gear set meshes with the second rack 12, and the connecting gear set 8 also meshes with the output gear set 3 and the motor speed-changing gear 4. The angle sensor 9 and the circuit board 5 are connected to the adjusting gear set, which can drive the angle sensor 9 to rotate.

[0029] The linkage between the transmission system and the rack and pinion converts the linear motion of the transmission system into the linear motion of the rack and pinion, and converts the handle position into the resistance value of the angle sensor 9. Furthermore, it linearizes the resistance value of the angle sensor 9, achieving real-time monitoring of the handle position. When opening or closing windows, if the door or window handle is not in the set position, the smart door and window electronic lock with position monitoring will automatically adjust to the correct position, further improving the flexibility and security of using the smart door and window electronic lock with position monitoring.

[0030] To facilitate control of the rack's movement range, limit structures are respectively provided at the outer ends of the first rack 11 and the second rack 12.

[0031] like Figure 3 As shown, the output gear set 3 is provided with a connecting hole, and one end of the handle A is set in the connecting hole. When the connecting hole rotates, it can drive the handle A to rotate together.

[0032] To facilitate the follow-up movement between the handle A and the connecting hole, the connecting hole on the output gear set 3 is set as a square hole.

[0033] like Figure 4 As shown, a gear 6 of the adjusting gear set is provided with a gear rotating shaft 61, and an angle sensor 9 is provided with a center hole 91. The rotating shaft 61 is configured to cooperate with the center hole 91. When the rotating shaft 61 rotates, it can drive the center hole to rotate together, thereby changing the resistance value of the angle sensor 9.

[0034] Circuit board 5 also has a through hole for the gear rotation shaft 61 to pass through. Circuit board 5 is located between one of the gears 6 of the adjusting gear set and the angle sensor 9.

[0035] Since the rotation of the angle sensor is driven by the second rack, the rotation process is not subject to compression by the transmission system, which extends the service life of the angle sensor and improves the economic efficiency of the electronic lock.

[0036] The present invention also provides a door or window equipped with the electronic lock described in the above embodiments.

[0037] The specific applications of this invention are as follows: When the motor starts, it drives the transmission gear set 4 to rotate, which in turn drives the connecting gear 8 that meshes with it to rotate. The connecting gear 8 drives the output gear 3 to rotate, and at the same time drives the first rack 11 to move. Through the movement of the first rack 11, the rotational motion of the connecting gear 8 is converted into the linear motion of the first rack.

[0038] When the first rack moves, it drives the second rack tooth 12 to move in a straight line, thereby driving the gears 6 and 7 in the adjusting gear set that mesh with the second rack to move. When gear 6 rotates, it drives the angle sensor 9 to rotate.

[0039] When angle sensor 9 rotates, circuit board 5 records its resistance value and converts it into the position of gear 3 via a control system within the circuit board. At startup, assuming the output gear 3 angle is 0°, the resistance value of angle sensor 9 is read and marked as 0%. The motor drives the transmission gear set 4 to continue rotating, and also drives other gear sets to rotate, until the first rack 11 and the second gear 13 move accordingly. When output gear 3 is at any position between 0° and 360°, the corresponding resistance value of angle sensor 9 increases linearly. When the first rack 11 and the second gear 13 stop, the motor stops rotating. The resistance value of angle sensor 9 at this point is marked as 100%. At this point, the correspondence between the position of output gear 3 and the resistance value of angle sensor 9 is complete.

[0040] In practical applications, when different window opening methods are required depending on the handle's stopping position, such as at 0°, 90°, 135°, and 180°, it is only necessary to define the corresponding sensor resistance values ​​at 0°, 90°, 135°, and 180° in the software. When the motor reaches the preset point of the sensor, it will stop moving.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
