Description of the embodiments
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments of the application. In the drawings, like reference numerals describe substantially similar components throughout the different views. Various specific embodiments of the application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the application. It is to be understood that other embodiments may be utilized or structural, logical, or electrical changes may be made to embodiments of the present application.
The present application provides a shield door for preventing signal leakage, which is suitable for the following situations: a closed region having an opening communicating with the open space, the signal within the closed region should not leak to a space outside the closed region. Such as cabinets, boxes, rooms, etc.
In particular, the shield door includes multiple glass sheets with a conductor (e.g., a metal strip) disposed between the two glass sheets. Shielding layers are provided on the inner/outer surfaces of the two glass plates, respectively. Since the metal material can form a waveguide, when a signal is lower than the cut-off frequency of the waveguide, the passing rate of electromagnetic waves is greatly reduced, thereby blocking and attenuating the electromagnetic waves. Thus, the shielding layer of the application is a metal layer. The implementation of the metal layer varies from metal layer to metal layer.
In particular, the shielding door includes a rim having a mounting slot in which one end of each of the two glass sheets is mounted. The shielding layer arranged on the glass plate stretches into the mounting groove, and the depth of the shielding layer positioned in the mounting groove is 10-20mm.
In some embodiments, the rim is a conductor, such as a metal rim. More specifically, the frame edge may be an aluminum alloy frame edge.
In some embodiments, the metal layer is a metal film formed by plating a glass substrate, and the metal of the metal film layer is mainly noble metal, such as gold film, silver film, palladium film, gold-silver, silver-copper composite film, or a metal film formed by combining oxidized metal materials. The preparation process comprises physical vapor deposition, chemical thermal decomposition method, etc.
In some embodiments, when a metal mesh is used for the metal layer, the metal used may be copper, aluminum, galvanized iron wire, silver wire, or silver plated wire mesh, or the like. The glass plate is manufactured by adopting an interlayer process, such as 6.35mm glass, 1.52mm film, metal wire mesh, 1.52mm film and 6.35mm glass, wherein the mesh range of the metal wire mesh is 100-400 meshes.
The technical scheme of the shielding door provided by the application is further described below through a few specific examples.
Examples
Fig. 1 is a schematic cross-sectional view of a part of a shielding door according to a first embodiment of the present application. The structure of the shielding door comprises a frame edge 1a and two layers of glass plates 2a. The frame edge 1a is provided with a mounting groove 11a, the end parts of the glass plates 2a are respectively fixed in the mounting groove 11a through fixing pieces 4a, a first conductor, namely a metal strip 3a, is arranged between the two layers of glass plates 2a, and the glass plates 2a and the fixing surfaces of the metal strip 3a and the mounting groove 11a are sealed through an adhesive 5 a.
As shown in the figure, A is the inner side of the shielding door and faces into the cabinet; b is the outer side of the shielding door and faces the outside of the cabinet; the signal in the enclosed area propagates from a to B in the direction of the arrow. For convenience of explanation, in this embodiment and the following embodiments, the multiple layer glass plate is defined as an inner layer glass plate near the a side and an outer layer glass plate near the B side. For both surfaces of the glass sheet, the surface facing the a side is defined as the inner surface and the surface facing the B side is defined as the outer surface.
As shown in fig. 1, the inner surface of the inner glass plate and the outer surface of the outer glass plate are respectively plated with a metal plating layer 21a. Further, the metal plating layer 21a extends to the end of the glass plate, and in this embodiment, the depth d of the inner and outer glass plates in the installation groove 11a is 20mm. According to experimental measurements, in the arrangement shown in fig. 1, the electromagnetic signal inside the cabinet is substantially leak-free.
In some embodiments, the height of the metal strip 3a is lower than the outer edge of the mounting groove 11a. Alternatively, the metal strip 3a is positioned in the mounting groove 11a so as not to be higher than the mounting groove 11a. By such an arrangement the possibility of leakage of electromagnetic signals can be further reduced.
In fig. 1, the inner and outer glass plates 2a are fixed to the mounting groove 11a by respective fixing members 4 a. The double glass plate may be fixed in the mounting groove 11a by a fixing member. The fixing member 4a may be fixed by glass commonly used in the art, such as a combination of screws and fixing plates.
The inner and outer glass plates 2a and the fixing surfaces of the metal strips 3a and the mounting grooves 11a are sealed by an adhesive 5 a. The purpose of the adhesive is to firmly adhere the glass plate 2a and the metal strip 3a in the mounting groove 11a. The amount of the adhesive varies depending on the composition of the adhesive, and generally, the thickness of the adhesive may be between 3 and 10 mm. However, it should be understood by those skilled in the art that the fixing of the inner and outer glass plates 2a, the metal strips 3a and the mounting grooves 11a may be also performed by other means in the prior art, not limited to the means of fig. 1.
Preferably, the width of the gap between the two glass sheets is 20-25mm. The smaller width between the glass sheets facilitates making the door thinner, thereby increasing the space within the cabinet and reducing the likelihood of damage.
Examples
Fig. 2 is a schematic partial cross-sectional view of a shielding door according to a second embodiment of the present application. In this embodiment, the same parts as those in the embodiment of fig. 1 will not be described again. One difference from the embodiment is that: the inner surface of the inner glass plate and the inner surface of the outer glass plate are respectively plated with a metal plating layer 21b. Further, the metal plating layer 21b extends to the end of the glass plate, and the depth d of the inner and outer glass plates in the installation groove 11b is 15mm.
Examples
Fig. 3 is a schematic cross-sectional view of a part of a shielding door according to a third embodiment of the present application. In this embodiment, the same parts as those in the embodiment of fig. 1 will not be described again. One difference from the embodiment is that: the outer surface, end and inner surface contacting with said mounting groove 11c of the inner glass plate 2c are plated with a metal plating layer 21c; the inner surface, end portions, and outer surface of the outer glass plate 2c that are in contact with the installation groove are plated with a metal plating layer 21c. Further, the metal plating layer 21c extends to the end of the glass plate, and the depth d of the inner and outer glass plates in the installation groove 11c is 10mm, which is smaller than that in the embodiment of fig. 1 and 2.
Examples
Fig. 4 is a schematic partial cross-sectional view of a shielding door according to a fourth embodiment of the present application. The present embodiment differs from the first embodiment in that the shielding layer in the glass plate in the third embodiment employs a wire mesh located in the glass layer. As shown in fig. 4, there are two glass sheets in total, and a wire mesh 21d is included between the glass layers 20d and 22d of the inner glass sheet. Further, the wire mesh 21d extends to the end of the glass sheet, and the depth d of the inner and outer glass sheets in the installation groove 11d is 15mm.
In order to achieve the purpose of better signal leakage prevention, in the first to fourth embodiments, the frame edge may further include a second conductor 6a, as shown in a partial structure schematic view of the shielding door in fig. 5. A second conductor 6a is arranged at the contact position of the frame edge 1a and the glass plate 2a, and is sealed by a sealing strip 7 a. The second conductor 6a can be made of aluminum foil, so that the shielding door provided by the application is fully covered by metal, has a tight structure, and can not leak signals.
The drawings in the above embodiments are schematic, and the structural relationships presented in the drawings are not actual dimensions or proportions. For example, the thickness of the shielding layer on an actual glass plate is very small relative to the thickness of the glass and is hardly distinguishable to the naked eye, and the actual scale cannot be used for illustration due to the limitation of the drawing, and thus the scale and the dimensions in the drawing of the present application are only for illustrating the relationship between the respective structures.
Application examples:
the shielding door can be applied to intelligent containers. The goods for selling that show in the intelligent packing cupboard have RFID label, have control module and thing UNICOM's module and various sensors in the intelligent packing cupboard, like the sensor that is used for detecting door switch. When the shielding door is detected to be opened, the control module scans the RFID tag once, and when the shielding door is detected to be closed, the control module scans the RFID tag once again, so that the commodity and the quantity of the commodity taken out by a consumer are determined, the selling information is sent to the background processing system through the commodity communication module, and the background processing system generates an order according to the selling information, so that payment operation is realized, and purchasing behavior is completed. Because the shielding door provided by the application is applied to the intelligent container, when a consumer takes goods, and the control module scans the RFID tag, the shielding door well shields the signal, so that the goods which are taken out of the shielding door by the consumer can not be scanned, the information can be accurately sold, the accident of order errors can not happen any more, the accuracy of the intelligent container is improved, a series of operations caused by the order errors are saved for the merchant, the manpower is saved, the reputation is improved, the time is saved for the consumer, and the consumption comfort is improved.
The above embodiments are provided for illustrating the present application and not for limiting the present application, and various changes and modifications may be made by one skilled in the relevant art without departing from the scope of the present application, therefore, all equivalent technical solutions shall fall within the scope of the present disclosure.
