Description

Technical Field

[0001] The present invention relates to the technical field of locks, and more particularly to a combined IoT intelligent bouncing lock. Background Art

[0002] In today's society, with rising living standards and continuous technological advancements, the demand for security locks is growing. As a crucial tool for protecting personal and property safety, locks have garnered widespread attention for their safety, convenience, and intelligence. However, existing lock technology still suffers from numerous shortcomings in practical applications, requiring urgent improvement and innovation.

[0003] Traditional pop-up locks are mostly mechanical, relying on the physical insertion and rotation of a key to unlock and lock. These mechanical locks present numerous security risks, including low security and vulnerability to prying or other technical methods. Furthermore, if the key is lost, forced opening is often necessary, which can damage the lock itself.

[0004] With the rapid development of electronic technology, electronic bounce locks have emerged. Compared to traditional mechanical bounce locks, electronic bounce locks offer significant security improvements. They can be opened with an electronic key, enhancing the security of traditional mechanical locks while also facilitating automatic unlocking recording. However, electronic bounce locks are not perfect. Due to limitations in lock size and installation, they typically employ a passive design, with power supplied by the electronic key during unlocking. This design results in the lock being powered off at all times, making it impossible to monitor the door's open / closed status and providing real-time visibility into the usage of the protected enclosure or facility. Furthermore, since the electronic key must be used to power the lock during unlocking, electronic key management cannot effectively meet on-site requirements.

[0005] Therefore, it is an urgent problem for those skilled in the art to develop a combined IoT smart bounce lock that can not only effectively improve the security of the lock but also realize intelligent management and monitoring. Summary of the Invention

[0006] In view of this, the present invention provides a combined IoT smart bounce lock that can not only effectively improve the security of the lock, but also realize intelligent management and monitoring.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] The embodiment of the present invention discloses a combined IoT smart bounce lock, comprising:

[0048] The lock body 1 is connected to the door panel; the lock body 1 includes: a lock body shell 11 and a handle 12. The outer surface of the lock body shell 11 is provided with a handle groove 111. The handle 12 is rotatably connected to the lock body shell 11. When the lock is in the locked state, the handle 12 is placed in the handle groove 111.

[0049] The lock core 2 includes a lock core housing 21, a lock tongue 22, a motor 23 and a motor bracket 24; the lock core housing 21 is placed in the lock body housing 11, the bottom of the lock tongue 22 is placed in the lock core housing 21, the bottom of the handle 12 is provided with a locking groove 121, and the top of the lock tongue 22 passes through the top wall of the lock core housing 21 and is placed in the locking groove 121; the motor 23 is placed in the motor bracket 24, the motor bracket 24 is connected to the lock core housing 21, and the motor bracket 24 and the lock core housing 21 are slid up and down along the inner wall of the lock body housing 11 and connected to the lock body housing 11; the output end of the motor 23 is connected to the cam 25, and the position corresponding to the motor bracket 24 and the cam 25 is provided with a pin hole 26, and a pin 27 is placed in the pin hole 26; the inner wall of the lock body housing 11 is provided with a pin limiting groove 112;

[0050] Control box 3 plugs into lock housing 11 and communicates with motor 23. Control box 3 is connected to an external communication device. Control box 3 controls motor 23 to rotate cam 25, causing pin 237 to exit pin retaining groove 112. This depresses lock cylinder housing 21, disengaging lock tongue 22 from locking groove 121 of handle 12. The handle 12 then springs open, allowing the door to be unlocked by rotating it. Control box 3 also connects to an external communication device via Bluetooth.

[0051] In order to further optimize the above technical solution, a mounting cavity 113 is provided at the bottom of the lock body shell 11 , the lock core 2 is placed in the mounting cavity 113 , and the ball limiting groove 112 is provided on the inner wall of the mounting cavity 113 .

[0052] To further optimize the above technical solution, the lock body 1 further includes a guide piece 28, which is installed in the installation cavity 113. Guide grooves 29 are provided on both sides of the lock cylinder housing 21, and both sides of the guide piece 28 are placed in the guide grooves 29. The arrangement of the guide piece 28 and the guide groove 29 can limit the upward and downward sliding unlocking process of the lock cylinder housing 21.

[0053] In order to further optimize the above technical solution, a battery is provided in the box in which the lock is installed, and the lock is powered by the original battery in the box.

[0054] To further optimize the above technical solution, the motor bracket 24 is connected to a magnetic bracket 211. A magnetic interface board 210 is connected to the side of the magnetic bracket 211 away from the motor bracket 24. The magnetic interface on the magnetic interface board 210 extends from the surface of the lock cylinder housing 21 and is electrically connected to the control box 3. The magnetic interface is connected to the control box 3 via a cable bus. The magnetic interface is connected to an external communication device (such as a mobile phone) via a magnetic communication cable. The magnetic end of the magnetic communication cable is attracted to the magnetic interface, and the other end is a socket end that plugs into the power socket of the external communication device to provide power to the control box 3.

[0055] To further optimize the above technical solution, a handle state detector 13 is provided in the handle groove 111. When the spring-up end of the handle 12 is connected to the lock tongue 22, the handle 12 presses the handle state detector 13. After the handle 12 springs back, it separates from the handle state detector 13. The state detector 13 can detect the state of the handle 12 and transmit the handle state to the control box 3, thereby realizing real-time monitoring of the door state.

[0056] To further optimize the above technical solution, a plug-in slot 31 is provided on the side where the control box 3 connects to the lock housing 11.

This plug-in connection ensures that the control box 3 is connected to the lock housing 11 and also electrically connects to the motor 23 and the magnetic interface.

[0057] To further optimize the above technical solution, a first return spring 212 is provided at the bottom of the lock cylinder housing 21. The first return spring 212 is connected to the inner wall of the mounting cavity 113. When the lock cylinder housing 21 moves downward to unlock, the first return spring 212 is compressed. When the handle 12 is opened, the lock cylinder housing 21 is released, and the lock cylinder housing 21 is restored to its original position under the action of the first return spring 212.

[0058] In order to further optimize the above technical solution, a second return spring is provided at the bottom of the lock tongue 22, and the second return spring is connected to the inner wall of the lock core housing 21. When the door needs to be locked, the handle is pressed into the handle groove 111, and the handle 12 presses the lock tongue 22 downward. Under the action of the second return spring, the lock tongue 22 moves upward, so that the lock tongue 22 is placed in the handle groove 111, and the handle 12 is locked.

[0059] To further optimize the above technical solution, a first torsion spring 213 is interposed between the cam 25 and the motor 23; a second torsion spring is installed at the connection between the handle 12 and the lock housing 11. When the cam 25 rotates to unlock the lock, the motor is powered off, and the cam 25 rotates and resets under the action of the first torsion spring 213, pushing the pin 27 out and placing it in the pin retaining groove 112, thereby locking the lock cylinder housing 21. When the handle 12 is pressed tightly against the handle groove 111, the second torsion spring is compressed. When the lock tongue 22 leaves the locking groove 121, the handle 12 is no longer restrained and is ejected by the second torsion spring, unlocking the lock.

[0060] In order to further optimize the above technical solution, the lock body shell 1 is connected to the door node bracket 4, the door node bracket 4 is connected to the mounting plate 5, and the mounting plate 5 is connected to the door panel.
