Description

Technical Field

[0001] This application relates to a door structure, and more particularly to a door structure with signal shielding function and a device equipped with the structure. Background Technology

[0002] Radio frequency (RF) technology has a high degree of identification accuracy. With the rapid development of the Internet and the Internet of Things (IoT) technologies, the application fields of RF technology are becoming wider and the specific application forms are becoming more diverse. For example, it can be used in the field of consumable management, which can greatly reduce the intensity of manual management, further improve the accuracy of management, and realize remote management through interconnection technology.

[0003] Radio frequency (RF) technology for consumable management typically involves cabinets with storage space. These cabinets have doors, and RF signal generators are installed inside. The consumables stored inside are managed through RF sensing, but it's crucial to prevent RF signals from leaking out of the cabinet. Usually, the doors are assembled from metal plates to shield the RF signals. However, metal materials are generally heavy and expensive. Furthermore, accessing the cabinet's interior often requires inspection, so the doors need to be made of transparent materials, such as glass or other transparent organic materials. However, these materials do not provide RF signal shielding. Since the door is a moving part relative to the cabinet, if a completely sealed structure is not formed when the door and cabinet are closed, RF signal leakage can still occur.

[0004] Therefore, there is a need in the prior art for a gate structure that can prevent radio frequency signal leakage. Utility Model Content

[0005] This application proposes a door structure with signal shielding function and a device equipped with the structure. The structure can effectively solve the problem of radio frequency signal leakage and has a simple structure.

[0006] This application relates to a door structure with signal shielding function, including a door frame, a base, a shielding film, and a shielding component. The base is disposed on the door frame, the shielding film is disposed on the inner side of the base, and the shielding component is circumferentially disposed on the door frame and closely connected to the shielding film.

[0007] The door frame has an mounting surface for assembling the base body; the door frame of the door structure includes a left stop bar, a right stop bar, an upper end cover, and a lower end cover that are assembled together; the upper end cover and the lower end cover are provided with shaft holes, and a rotating shaft is provided in the shaft holes; at least one of the left stop bar, right stop bar, upper end cover, and lower end cover is provided with a reinforcing member; the lower end cover is provided with a boss, and the base body is supported on the boss; the base body is a transparent base body, or the shielding component is shielding cotton; the shielding component is a flexible shielding component; the door body is provided with a handle, and the handle is integrally formed with the door frame.

[0008] This application also relates to a device with signal shielding function, including a door structure and a cabinet, wherein the door structure is installed on the cabinet, and the door structure is the door structure described above.

[0009] This application enables the door to have signal shielding capabilities by setting a shielding film on the substrate and placing a shielding component between the shielding film and the cabinet. This allows the door to be made of non-metallic materials, reducing its cost and weight. Furthermore, this application forms a complete and effective shielding component between the door and the cabinet, effectively preventing leakage of radio frequency signals. This application offers technical advantages such as low cost, light weight, good shielding effect, and ease of processing. Attached Figure Description

[0011] Figure 2 This is a cross-sectional view of the door structure according to this application.

[0012] Figure 3 This is a schematic diagram of the connection between the lower end cover of the door structure and the transparent substrate.

[0013] Figure 4 This is a schematic diagram of a device equipped with the door structure described in this application. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0015] According to this application, a door structure with signal shielding function includes a door frame 1, a transparent substrate 2, a shielding film 3, and a shielding element 4. The transparent substrate 2 is disposed on the door frame 1, the shielding film 3 is disposed on the inner side of the transparent substrate 2, and the shielding element 4 is circumferentially disposed on the door frame 1 and continuously disposed with the shielding film 3. Figure 2As shown, the door frame 1 has a mounting surface for assembling the transparent substrate 2, which can be a wedge-shaped bevel. The shielding film 3 is continuously arranged along the length of the transparent substrate 2 to avoid radio frequency signal leakage points. The shielding component 4 can be in the form of flexible cotton or the like.

[0016] like Figure 1 As shown, the door frame 1 of the door structure is assembled from a left stop bar 11, a right stop bar 12, an upper end cover 13, and a lower end cover 14. The upper end cover 13 and the lower end cover 14 can be made of metal or injection molded from a high-molecular-weight organic synthetic material to form a structure that assembles with the left stop bar 11 and the right stop bar 12. The upper end cover 13 has a shaft hole 131, and similarly, the lower end cover 14 has a shaft hole. The centers of the two shaft holes are on the same vertical line to ensure that after the door is fixed to the cabinet via upper and lower door hinges, the door can rotate around the vertical line to form an opening and closing relationship with the cabinet. To accommodate different cabinet heights, the door height will also vary accordingly. The left stop bar 11 and the right stop bar 12, which make up the door frame 1, can use profiles as the main material. The profiles can be made of metal, such as aluminum alloy; or they can be made of high-molecular-weight organic synthetic materials, such as PVC, which are extruded into profiles. When the door is tall, in order to ensure the rigidity and strength of the organic synthetic material profile, a reinforcing member 11, preferably a metal member, can be inserted into the profile to fit tightly with it. This will give the left and right baffles 11 good rigidity and strength and prevent the door from deforming.

[0017] A mounting surface is provided between the door frame 1 and the transparent substrate 2 for fixed connection. This connection can be achieved through adhesive bonding, interlocking, or fastening. When using adhesive bonding, considering the weight of the transparent substrate 2, to prevent the transparent substrate 2 from detaching from the door frame 1, as follows... Figure 3 As shown, a boss 141 can be designed on the lower end cover 14 to support the transparent substrate 2 when the door is placed vertically. The transparent substrate 2 can be made of glass or a transparent polymer organic synthetic material, such as acrylic. When the transparent substrate 2 is fastened to the door frame 1, holes can be made in the transparent substrate 2, and fasteners can be used to fasten it to the door frame 1.

[0018] The transparent substrate 2 can be tightly connected to the door frame 1 to form a whole through adhesive, interlocking, or fastening. A shielding film 3 can be attached to the transparent substrate 2, and a shielding element 4 is provided around the perimeter of the shielding film 3. The shielding element 4 is flexible and can form a flexible sealing structure with the cabinet to adapt to the gap between the door and the cabinet, forming a good shielding structure and thus preventing radio frequency signal leakage from the cabinet and door. For aesthetic purposes, a concealed handle can also be installed on the door, such as... Figure 2 and 4 As shown, an L-shaped handle can be installed on the door body, and the L-shaped handle is integrally formed with the door frame 1.

[0019] This application may also relate to a device, such as Figure 4 As shown, it includes a cabinet and a door structure as described above. When the door is closed, the shielding component 4 can form a complete shielding structure with the shielding door frame and the shielding cabinet.

[0020] Although the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit this application. Any person skilled in the art to which this application pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application; however, the scope of patent protection of this application shall still be determined by the scope defined in the appended claims.
