For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0030] like Figures 1 to 4 As shown, an embodiment of the utility model provides a lock assembly 100, which includes a lock body 10, an iron plate 20 and a protective shell 30, a connecting portion 11 is provided on the side of the lock body 10; the iron plate 20 is fixed to the connecting portion 11; the protective shell 30 is wrapped around the outer surface of the iron plate 20, and the protective shell 30 is detachably connected to the iron plate 20.

[0031] Based on the above technical solution, the lock assembly 100 is a magnetic lock structure, which includes a lock body 10, an iron plate 20 and a protective shell 30. The lock body 10 is the core part of the lock assembly 100 and is composed of an electromagnet. When current passes through the electromagnet of the lock body 10, a strong magnetic field is generated to attract the iron plate 20, so that a strong magnetic force is generated between the iron plate 20 and the lock body 10, and the door is tightly sucked, thereby achieving locking; when the access control system recognizes a door opening signal such as swiping a card or entering a password, the current of the electromagnet will be cut off, the magnetic field disappears, and the magnetic force between the iron plate 20 and the lock body 10 also disappears, and the door can be opened at this time. Among them, the protective shell 30 (or protective cover, protective cover) mainly plays a protective and decorative role. The protective shell 30 is wrapped around the outer surface of the iron plate 20, which can effectively protect the iron plate 20 and prevent the iron plate 20 from being eroded by dust, water vapor, pollutants, etc. in the external environment, thereby extending the service life of the iron plate 20 or the lock assembly 100. Especially for locks used outdoors, the protective shell 30 can effectively prevent the iron plate 20 from rusting and corroding, thereby ensuring the stability and reliability of the magnetic lock.

[0032] In this embodiment, a protrusion 21 is provided on one side of the iron plate 20 facing the protective shell 30 , and a groove 31 is provided on one side of the protective shell 30 facing the iron plate 20 , and the protrusion 21 is embedded in the groove 31 .

[0033] Specifically, the raised portion 21 of the iron plate 20 is embedded in the groove portion 31 of the protective shell 30, so that when the protective shell 30 wraps the iron plate 20, the two fit more closely, forming an effective sealing barrier to prevent external pollutants such as dust and water vapor from entering the gap between the iron plate 20 and the protective shell 30, thereby further improving the protective performance of the iron plate 20.

[0034] As an implementation method, Figure 2 and Figure 3 As shown, a plurality of protrusions 21 are provided on one side of the iron plate 20 facing the protective shell 30 , and a plurality of grooves 31 are provided on one side of the protective shell 30 facing the iron plate 20 , and each protrusion 21 is embedded in each groove 31 in a one-to-one correspondence.

[0035] Specifically, this embodiment increases the number of connection points between the iron plate 20 and the protective shell 30 through a one-to-one corresponding embedding design of multiple protrusions 21 and multiple grooves 31, so as to make the connection between the iron plate 20 and the protective shell 30 more stable, and prevent the overall stability from decreasing due to loose connection. The embedding connection of multiple protrusions 21 and grooves 31 further prevents external pollutants such as dust and water vapor from entering the gap between the iron plate 20 and the protective shell 30, thereby improving the protective performance of the iron plate 20 and extending its service life.

[0036] As an implementation method, Figure 3As shown, a magnetic member 32 is disposed on one side of the protective shell 30 facing the iron plate 20 . The magnetic member 32 is embedded in the groove portion 31 or the magnetic member 32 and the groove portion 31 are spaced apart.

[0037] Specifically, the magnetic member 32 provides a magnetic adsorption force for the connection between the iron plate 20 and the protective shell 30. Regardless of whether the magnetic member 32 is embedded in the groove portion 31 or spaced apart from the groove portion 31, this magnetic force can effectively enhance the connection stability between the two. The magnetic adsorption characteristics of the magnetic member 32 enable the protective shell 30 to be aligned and fitted with the iron plate 20 more quickly and accurately during installation, thereby improving the installation efficiency. During disassembly, the magnetic force of the magnetic member 32 also facilitates the rapid separation of the protective shell 30 from the iron plate 20. In this embodiment, the magnetic member 32 can be designed as a compact structure hidden in the groove portion 31, which will not affect the appearance of the protective shell 30.

[0038] As an implementation method, Figure 2 or Figure 3 As shown, the protective shell 30 is provided with a first mounting hole 33, and the iron plate 20 is provided with a second mounting hole 22 corresponding to the first mounting hole 33; the lock assembly 100 includes a fastener, which passes through the first mounting hole 33 and the second mounting hole 22 to fix the protective shell 30 to the iron plate 20.

[0039] Specifically, this embodiment ensures that the connection between the protective shell 30 and the iron plate 20 is firm and reliable by respectively providing a first mounting hole 33 and a second mounting hole 22 on the protective shell 30 and the iron plate 20, and fixing them with fasteners (such as screws, bolts, etc.). This mechanical connection method has higher connection strength and stability than simple magnetic connection or snap connection.

[0040] In the actual installation process, the protective shell 30 can be fixed on the iron plate 20 by simply passing the fastener through the first mounting hole 33 and the second mounting hole 22 and tightening. This installation method is simple and fast, does not require complicated operation steps, and greatly saves installation time. When the protective shell 30 needs to be removed to maintain or replace the iron plate 20, the two can be easily separated by simply loosening the fastener.

[0041] It is understandable that, since the first mounting hole 33 and the second mounting hole 22 are preset, the positions and number of the holes can be adjusted according to actual needs to accommodate iron plates 20 and protective shells 30 of different sizes or shapes. When fasteners are used to fix the protective shell 30 and the iron plate 20, the protective shell 30 is further tightly attached to and wrapped around the outer surface of the iron plate 20, thereby improving the sealing of the lock assembly 100, helping to prevent pollutants such as dust and water vapor from entering the interior of the lock, and protecting the iron plate 20 from erosion and damage.

[0042] As an implementation method, Figure 3As shown, the protective shell 30 includes a first side surface 35 and a second side surface 36 that are oppositely disposed. The first side surface 35 and / or the second side surface 36 are provided with a notch 34 for fingers to be inserted.

[0043] Specifically, a notch 34 is provided on the first side surface 35 (right side surface) or the second side surface 36 (left side surface) of the protective shell 30 to provide a clear gripping and operating point for the user, so that the user can grasp and move the protective shell 30 more easily, especially when the lock assembly needs to be installed, disassembled or adjusted, thereby greatly improving the convenience of operation.

[0044] As an implementation method, Figure 5 As shown, the lock body 10 includes a lock core 12 and a U-shaped housing 13 , and the lock core 12 is disposed in the U-shaped housing 13 .

[0045] Specifically, the U-shaped housing 13 is a U-shaped structure, and the U-shaped housing 13 surrounds the outer periphery of the lock core 12, and the lock core 12 and the U-shaped housing 13 are assembled into a lock body 10 with a stable structure. In this embodiment, the lock core 12 is arranged in the U-shaped housing 13, which can effectively protect the lock core 12 from erosion and damage from the external environment. For example, the U-shaped housing 13 can prevent dust, moisture, chemicals, etc. from entering the interior of the lock core 12, thereby affecting the normal operation of the lock core 12.

[0046] As an implementation manner, the U-shaped shell 13 and / or the protective shell 30 are both made of plastic.

[0047] Specifically, plastic materials such as PVC generally have excellent acid resistance, alkali resistance, and corrosion resistance, so that the U-shaped housing 13 and the protective shell 30 can remain stable in outdoor environments and are not easily corroded or damaged.

[0048] In a second aspect, an embodiment of the present invention provides an access control system, including a controller and a lock assembly 100 .

[0049] Specifically, the lock assembly 100 is communicatively connected to the controller. When current passes through the electromagnet of the lock body 10, a magnetic field is generated to attract the iron plate 20, so that a strong magnetic force is generated between the iron plate 20 and the lock body 10, which tightly sucks the door, thereby achieving locking; when the access control system recognizes a door opening signal such as swiping a card or entering a password, the controller sends an instruction to cut off the current of the electromagnet, the magnetic field disappears, and the magnetic force between the iron plate 20 and the lock body 10 also disappears, and the door can be opened at this time.

[0050] In this embodiment, the access control system realizes efficient, safe and intelligent management of the entrance and exit by integrating the controller and the lock assembly 100. The access control system not only provides functions such as access control, security prevention, and convenient management, but also has significant advantages such as convenient operation, safety protection, strong security, data statistics, improved work efficiency and optimized personnel management.
