Description

Technical Field

[0001] This utility model belongs to the field of municipal facilities technology, and in particular relates to an encrypted electronic key with linear motion of the inner rod. Background Technology

[0002] In existing technologies, purely mechanical keys are mainly used to open or close manhole cover locks. However, purely mechanical keys are simple in structure, easily damaged, and easily copied, rendering smart manhole covers ineffective at preventing theft.

[0003] In addition, existing technologies also include purely mechanical magnetic emergency keys, typically made of stainless steel. Different magnetic groups are inserted into holes inside the key shaft to achieve magnetic encryption. However, in some keys, the magnets in the holes may fall out during use, rendering the key unusable. This is mainly due to poor machining or wear during use. In other keys, the locating pin may fall out, also rendering the key unusable. Furthermore, some keys can be stolen or even counterfeited, which represents a significant vulnerability. Utility Model Content

[0004] The purpose of this utility model is to provide an encrypted electronic key with linear motion of the inner rod, which solves the technical problems of traditional manhole cover keys in the prior art, which have simple structures that are easy to copy or keys that are easily damaged and cannot be unlocked.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An encrypted electronic key with linear motion of the inner rod includes: an upper shell and a lower shell, which are interlocked to form a housing. One end of the housing has a tail shell, and the other end of the housing is connected to an outer key rod. The outer key rod has a hollow structure, through which an inner key rod passes. The inner key rod is connected to a slider and can slide along the length of the outer key rod. The other end of the slider is connected to the output end of a motor. The motor is controlled by a main circuit board, which is electrically connected to a battery. The end of the inner key rod has a permanent magnet. When the motor drives the inner key rod to extend or retract along its length so that the permanent magnet is aligned with the action part of the lock body, the unlocking function is achieved. A Hall sensor is provided at the base of the outer key rod and is electrically connected to the main circuit board. The Hall sensor is protected by a sensor housing.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1-5 As shown, an encrypted electronic key with linear motion of the inner rod is characterized by comprising: an upper shell 1 and a lower shell 2, which are interlocked to form a housing. One end of the housing has a tail shell 5, and the other end of the housing is connected to an outer key rod 3. The outer key rod 3 has a hollow structure, and an inner key rod 4 is inserted inside it. The inner key rod 4 is connected to a slider 11 and can slide along the length of the outer key rod 3. The other end of the slider 11 is connected to the output end of a motor 14. The motor 14 is controlled by a main circuit board 16, which is electrically connected to a battery 17. The end of the inner key rod 4 has a permanent magnet 6. When the motor 14 drives the inner key rod 4 to extend and retract along its length so that the permanent magnet 6 is aligned with the action part of the lock body, the unlocking function is realized. A Hall sensor 9 is provided at the root of the outer key rod 3. The Hall sensor 9 is electrically connected to the main circuit board 16, and the Hall sensor 9 is protected by a sensor housing 10.

[0022] It should be noted that the outer key rod 3 is a hollow structure, the inner key rod 4 is a rod-shaped structure, and the volume of the permanent magnet 6 is relatively thicker than the body of the inner key rod 4. Therefore, the outer key rod 3 has space for the permanent magnet 6 to extend and retract at the position corresponding to the position of the permanent magnet 6. The slider 11 slides horizontally under the action of the motor 14, thereby actuating the extension and retraction of the inner key rod 4. The Hall sensor 9 can sense whether the unlocking and locking positions have been reached.

[0023] In a preferred embodiment of the present invention, the rear of the housing has a secondary circuit board 18, on which a dual-color light button 19, a dual-color indicator light 20 and a charging interface 21 are provided, and the secondary circuit board 18 is electrically connected to the main circuit board 16.

[0024] In a preferred embodiment of this utility model, a helical spring 12 is fitted on the output end of the motor 14, and the helical spring 12 transmits power to the output end of the motor 14 through a transmission pin 13.

[0025] In a preferred embodiment of the present invention, a slider pressure plate 15 is provided between the upper shell 1 and the main circuit board 16, and the slider pressure plate 15 guides and limits the slider 11.

[0026] In a preferred embodiment of this utility model, the main circuit board 16 has a wireless communication module, which exchanges data with a smartphone or remote platform.

[0027] In a preferred embodiment of this utility model, a side positioning pin 8 is provided on the outer rod 3 of the key, which can help the key to be positioned.

[0028] In a preferred embodiment of this utility model, a plug 7 is fitted at the end of the outer key rod 3 to prevent external debris from entering, and also to prevent the inner key rod 4 from coming out.

[0029] Brief description of working principle:

[0030] The key described in this application is an electronic key specifically designed for smart manhole covers. As the name suggests, it is a key that can be electronically controlled. In use, the electronic key is wirelessly connected and controlled via a smartphone or remote platform to unlock and lock the mechanical lock installed on the smart manhole cover. To use, first press and hold the metal dual-color indicator button 19 on the key for two seconds to power it on. After powering on, the dual-color indicator light 20 will turn red. Then, open the dedicated app on your smartphone and tap the following: Connect via Bluetooth to establish a Bluetooth wireless communication module connection between the phone and the key; at this time, the dual-color indicator button 19 will turn blue. Automatic authentication is required; only authorized personnel and an authorized key can officially authorize the key via the mobile app. Otherwise, the key will not proceed with the subsequent motor action. Then, tap the unlock button on the app. The motor 14 inside the key will start rotating, pushing the inner rod 4 of the key a short distance to the right, thus positioning the permanent magnet 6 inside the inner rod 4. The key can then be inserted into the lock hole of the smart manhole cover to unlock it. Finally, tap the lock button on the app, and the motor 14 inside the key will unlock and reverse until it returns to its original position and stops.
