DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. 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.

[0031] In the related art, in order to facilitate the installation of the lock body, a barb is provided on the lock body and a barb groove is provided on the mounting plate, and the lock body is pre-installed by plugging and fitting the barb into the barb groove. However, this will make the structure of the mounting plate and the lock body more complicated, the installation more troublesome, and the cost is high.

[0032] In view of this, if Figures 1 to 4 As shown, an embodiment of the utility model provides a magnetic lock structure, which is hereinafter referred to as a magnetic lock 100. The magnetic lock 100 includes a lock body 1 and a mounting plate 2. The lock body 1 includes a lock core 11, a cover plate 12 and a U-shaped shell 13. The lock core 11 is arranged in the U-shaped shell 13, the cover plate 12 covers a part of the opening of the U-shaped shell 13 and abuts against the lock core 11, and lock ears 14 are provided at the left and right ends of the U-shaped shell 13; the mounting plate 2 is attached to the top surface of the U-shaped shell 13 and is fixedly connected to the U-shaped shell 13, and a first magnetic member 15 is provided on the surface of the mounting plate 2 facing the U-shaped shell 13, and a second magnetic member 16 facing the first magnetic member 15 is provided on the top surface of the U-shaped shell 13, and the magnetism of the first magnetic member 15 and the second magnetic member 16 are opposite.

[0033] In this embodiment, the lock core 11 is an electromagnet. When current passes through the lock core 11, the lock core 11 will generate magnetic force to attract and lock the door; when the current is disconnected, the magnetic force of the lock core 11 disappears and the door can be opened freely. This is the basic working principle of the magnetic lock 100.

[0034] The U-shaped shell 13 is a U-shaped structure, and the U-shaped shell 13 surrounds the outer periphery of the lock core 11, the lock core 11 occupies a part of the space in the U-shaped shell 13, the cover plate 12 covers part of the opening of the U-shaped shell 13 and abuts against the lock core 11, and the lock ears 14 at the left and right ends of the U-shaped shell 13 are used to fix the lock core 11 and the cover plate 12, so that the lock core 11, the cover plate 12 and the U-shaped shell 13 are assembled into a lock body 1 with a stable structure. During installation, the first magnetic member 15 is first fixed on the surface of the mounting plate 2 facing the U-shaped shell 13, and the second magnetic member 16 is fixed on the top surface of the U-shaped shell 13, and the first magnetic member 15 and the second magnetic member 16 are arranged opposite to each other. The first magnetic member 15 and the second magnetic member 16 can be magnetic sheets or magnetic blocks (preferably magnetic sheets), and their shapes can be square, diamond, circular or other shapes, which are not specifically limited in this embodiment.

[0035] Based on the above technical solution: during installation, first use screws to fix the mounting plate 2 to the surface of the door frame, and then align the second magnetic member 16 on the U-shaped shell 13 with the first magnetic member 15 on the mounting plate 2. Since the first magnetic member 15 and the second magnetic member 16 have opposite magnetic properties and are mutually attracted, the U-shaped shell 13 can be quickly attached to the mounting plate 2. When the U-shaped shell 13 is temporarily attracted to the mounting plate 2, the U-shaped shell 13 is fixed to the mounting plate 2 with screws, thereby achieving the installation of the U-shaped shell 13. In this way, there is no need to manually lift the U-shaped shell 13, and there is no need to significantly modify the structures of the mounting plate 2 and the lock body 1. It is only necessary to fix the two magnetic members to the mounting plate 2 and the U-shaped shell 13 respectively, so that the installation of the lock body 1 can be successfully completed. The overall structural process is convenient and efficient.

[0036] It should be understood that the current magnetic lock 100 is usually made of aluminum alloy or stainless steel. These materials have good strength and corrosion resistance and can ensure the stability of the magnetic lock 100, but at the same time these materials also lead to a higher manufacturing cost of the magnetic lock 100.

[0037] As an implementation manner, the locking ear 14 and the cover plate 12 are both made of plastic.

[0038] In this embodiment, the lock core 11 is made of an electromagnet, and the U-shaped housing 13 is made of aluminum alloy. The U-shaped housing 13 and the lock core 11 of the magnetic lock 100 are the main force-bearing components, which can effectively withstand external stress and ensure the stability of the magnetic lock 100 during use. The lock ear 14 and the cover plate 12 are not force-bearing components. The lock ear 14 and the cover plate 12 are made of plastic material, and the density of plastic is usually low, about 0.9g / cm 3 Up to 2.0g / cm 3 The density of aluminum alloy is usually between 2.5g / cm 3 Up to 2.8g / cm 3 In the case of the same volume, plastic is lighter than aluminum alloy.

[0039] Specifically, the lock ear 14 and the cover plate 12 can be made of ABS material, which is a commonly used engineering plastic. Its full name is acrylonitrile-butadiene-styrene copolymer. This plastic is made of acrylonitrile, butadiene and styrene in a certain proportion. It has high strength and hardness, and has good impact resistance. It is not easy to break when hit by external force. If the lock ear 14 and the cover plate 12 are made of plastic material, the weight of the lock body 1 can be reduced, and the U-shaped shell 13 can be prevented from being adsorbed on the mounting plate 2 and falling off due to excessive weight. More importantly, the price of plastic is cheaper than aluminum alloy, which can reduce the cost of the lock body 1.

[0040] As an implementation method, Figure 2and Figure 3 As shown, a plurality of first magnetic parts 15 are provided on the surface of the mounting plate 2 facing the U-shaped shell 13, and the plurality of first magnetic parts 15 are arranged at equal intervals along the extension direction of the mounting plate 2. A plurality of second magnetic parts 16 are provided on the top surface of the U-shaped shell 13, and each second magnetic part 16 corresponds one by one to each first magnetic part 15.

[0041] Specifically, there is a magnetic attraction between the first magnetic member 15 on the mounting plate 2 and the second magnetic member 16 on the U-shaped shell 13. When the second magnetic member 16 on the U-shaped shell 13 is aligned with the first magnetic member 15 on the mounting plate 2, each second magnetic member 16 and each first magnetic member 15 will attract each other.

[0042] In this embodiment, multiple magnetic parts are arranged. When multiple first magnetic parts 15 are paired with corresponding second magnetic parts 16, the magnetic forces generated therebetween are superimposed on each other. Multiple first magnetic parts 15 are arranged at equal intervals along the surface of the mounting plate 2, which more evenly distributes the magnetic force, reduces the load of a single magnetic part, and disperses the scope of action of the magnetic attraction, thereby increasing the adsorption force between the U-shaped shell 13 and the mounting plate 2, ensuring that the pre-installation of the U-shaped shell 13 is more secure.

[0043] As an implementation method, Figure 5 As shown, a first mounting groove 17 is provided on the surface of the mounting plate 2 facing the U-shaped shell 13 , a second mounting groove 18 is provided on the top surface of the U-shaped shell 13 , the first magnetic member 15 is embedded in the first mounting groove 17 , and the second magnetic member 16 is embedded in the second mounting groove 18 .

[0044] Specifically, the first mounting groove 17 is located on the surface of the mounting plate 2, and the second mounting groove 18 is located on the top surface of the U-shaped shell 13. The first mounting groove 17 and the second mounting groove 18 provide fixed positions and supports for the installation of the first magnetic member 15 and the second magnetic member 16, respectively, to ensure that the first magnetic member 15 and the second magnetic member 16 can be firmly embedded therein and are not easy to loosen or fall off. When in use, the first magnetic member 15 and the second magnetic member 16 are embedded in the corresponding mounting grooves to form a tight connection between the mounting plate 2 and the U-shaped shell 13. During installation, it is only necessary to embed the magnetic member into the corresponding mounting groove, and no additional fixing tools or steps are required.

[0045] As an implementation method, Figure 5 As shown, the first magnetic member 15 is flush with the surface of the mounting plate 2 , and the second magnetic member 16 is flush with the top surface of the U-shaped housing 13 .

[0046] Specifically, in order to ensure that the U-shaped shell 13 fits the surface of the mounting plate 2 as closely as possible, the first magnetic member 15 is designed to be flush with the surface of the mounting plate 2, and the second magnetic member 16 is designed to be flush with the top surface of the U-shaped shell 13 in this embodiment. This design, on the one hand, can ensure that the contact surface between the mounting plate 2 and the U-shaped shell 13 is smooth and complete, maximize the contact area between the two surfaces, and avoid the presence of a gap between the mounting plate 2 and the U-shaped shell 13. On the other hand, when the magnetic member is flush with the mounting plate 2 or the top surface of the U-shaped shell 13, the entire magnetic lock 100 device looks more beautiful. In addition, the flush surface can reduce the entry of dust and other tiny particles into the gap between the mounting plate 2 and the U-shaped shell 13, and reduce the accumulation of dust or the entry of dust into the interior of the U-shaped shell 13.

[0047] As an implementation manner, the width of the first installation groove 17 gradually decreases from a direction away from the U-shaped shell 13 to a direction close to the U-shaped shell 13 , and the shape of the first magnetic member 15 is adapted to the shape of the first installation groove 17 .

[0048] It should be understood that if Figure 4 and Figure 6 As shown, when installing the magnetic lock 100, the mounting plate 2 is generally installed at the lower edge of the upper position of the door frame. In this case, there is a risk that the first magnetic member 15 will fall downward from the first mounting groove 17. Based on this, in this embodiment, Figure 6 As shown, the first mounting groove 17 is in an inverted trapezoidal shape, and the first mounting groove 17 gradually becomes smaller from the inside to the outside, that is, the closer to the U-shaped shell 13, the smaller the groove width of the first mounting groove 17. During installation, the first magnetic component 15 is first inserted into the first mounting groove 17 from the edge of the mounting plate 2 to stably embed or engage the first magnetic component 15 in the first mounting groove 17 to ensure that the first magnetic component 15 will not fall off the surface of the mounting plate 2.

[0049] Same destination, Figure 7 Another modified embodiment of the first mounting groove 17 is shown. In this embodiment, the first mounting groove 17 is in a step shape, and the inner diameter of the step away from the U-shaped shell 13 is larger than the inner diameter close to the U-shaped shell 13, so as to stably embed the first magnetic component 15 in the first mounting groove 17 to ensure that the first magnetic component 15 will not fall off the surface of the mounting plate 2.

[0050] Same destination, Figure 8 Another modified embodiment of the first mounting groove 17 is shown. The first mounting groove 17 is arc-shaped. The side of the first mounting groove 17 away from the U-shaped shell 13 has a larger aperture. The first magnetic component 15 is stably embedded in the first mounting groove 17 to ensure that the first magnetic component 15 will not fall off the surface of the mounting plate 2.

[0051] As an implementation mode, a positioning groove is provided on the surface of the mounting plate 2 facing the U-shaped shell 13, and a positioning column is provided on the top surface of the U-shaped shell 13, and the positioning column is embedded in the positioning groove (not shown in the drawings).

[0052] Specifically, the precise matching of the positioning groove and the positioning column has the following advantages: first, it can ensure that the U-shaped housing 13 and the mounting plate 2 are correctly connected during installation, avoiding installation deviation or incomplete alignment caused by misalignment; second, the positioning groove and the positioning column simplify the installation process and reduce the possibility of human operation errors. The installer only needs to embed the positioning column into the positioning groove to complete the installation quickly and accurately, saving time and labor costs; third, the combination of the positioning groove and the positioning column not only provides correct positioning, but also increases the connection stability between the mounting plate 2 and the U-shaped housing 13. The risk of loosening or falling off of the U-shaped housing 13 due to vibration or external force during use is reduced.

[0053] As an implementation method, Figure 2 and Figure 4 As shown, a control mainboard (not shown in the drawings) is disposed in the accommodation cavity enclosed by the cover plate 12 and the U-shaped shell 13. The control mainboard is provided with an LED lamp. A lamp hole 19 is disposed on the bottom surface of the U-shaped shell 13, and a lamp cover is disposed over the lamp hole 19.

[0054] In this embodiment, the control main board is installed in the accommodation cavity enclosed by the cover plate 12 and the U-shaped housing 13, which effectively utilizes the internal space of the U-shaped housing 13, and the control main board is safely placed without being disturbed or damaged by the external environment. Among them, the design of the lamp hole 19 and the lampshade enables the LED light to be illuminated through the lamp hole 19 on the bottom surface of the U-shaped housing 13, providing a prompt for the surrounding environment. At the same time, the lampshade can protect the LED light from external collisions and extend the service life of the LED light.

[0055] As an implementation manner, the locking ear 14 is made of a light-conducting material or a non-light-conducting material.

[0056] In practical applications, the lock ear 14 is generally made of a non-light-conducting material, that is, the lock ear 14 is non-light-conducting. In this embodiment, the lock ear 14 can be made of a light-conducting material, that is, the lock ear 14 is light-conducting. For example, the lock ear 14 is made of transparent plastic. On the one hand, the transparent lock ear 14 can provide a more modern and beautiful appearance; on the other hand, the transparent lock ear 14 makes the control motherboard in the accommodating cavity enclosed by the cover plate 12 and the U-shaped shell 13 visible, and the light emitted by the LED lamp can also be irradiated through the lock ear 14, thereby enhancing the lighting effect of the lock body 1, especially in a dark environment, and can be used as a lighting prompt.

[0057] On the other hand, an embodiment of the present invention provides a door lock assembly, including a magnetic attraction member and a magnetic lock 100 .

[0058] In actual applications, the magnetic lock 100 is usually installed inside the door frame, and the magnetic attraction component is installed in a hidden position on the door, so that the door lock assembly is more concealed, which can improve the security of the door lock and prevent external damage or illegal intrusion.

[0059] When the door is closed, magnetic attraction will be generated between the magnetic attraction piece and the magnetic lock 100, so that the door is tightly closed. When opening the door, just press the switch, and the control motherboard will control the power off, the magnetic force of the magnetic lock 100 will be released, and the door can be easily opened. This switching method is simple and fast, and is suitable for places that need to be opened and closed frequently.

[0060] It is understandable that, since there is no direct mechanical contact or friction between the magnetic attraction member and the magnetic lock 100, compared with a traditional door lock, this door lock assembly can reduce mechanical wear, extend the service life of the door lock assembly, and reduce maintenance costs. Of course, the door lock assembly of this embodiment is suitable for the installation of various doors, including doors of different materials such as wooden doors and metal doors, and is also suitable for different types of door frames.
