Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum-plastic composite panels, and specifically relates to an electromagnetic shielding aluminum-plastic composite panel. Background Technology

[0002] With the rapid development of electronic, communication, and information technologies, electromagnetic waves are increasingly used in daily life and industrial production. However, the widespread use of electromagnetic waves has also brought about problems such as electromagnetic interference (EMI) and electromagnetic radiation pollution. These problems may not only cause abnormal operation of electronic equipment, but also pose potential risks to human health. Electromagnetic shielding aluminum-plastic composite panels have been widely used due to their excellent electromagnetic wave shielding performance. They can effectively reduce electromagnetic interference, protect sensitive equipment from the influence of external electromagnetic waves, and provide people with a safer electromagnetic environment.

[0003] In existing technologies, traditional electromagnetic shielding materials mainly include metal sheets and metal meshes. Although these materials can effectively shield electromagnetic waves to a certain extent, their material properties make them generally heavy. This not only increases transportation and installation costs but also brings inconvenience to practical applications, especially in places requiring frequent personnel access, such as hospitals and computer rooms, where the application of traditional materials is particularly cumbersome. These environments require shielding measures that can be quickly closed and opened to ensure people's safety and provide flexible access management. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides an electromagnetic shielding aluminum-plastic composite panel, comprising:

[0027] The frame structure 100 includes a composite plate 101, a surface aluminum plate 102 fixedly installed on the outer surface of the composite plate 101, a plastic core layer 103 disposed on the inner surface of the composite plate 101, and a bottom aluminum plate 104 fixedly installed on the outer surface of the composite plate 101.

[0028] The drive mechanism 200 includes a door frame 201, a detector 202 disposed on the outer surface of the door frame 201, and an opening and closing assembly 203 for switching the composite panel 101.

[0029] The detector 202 is used to sense passing pedestrians and automatically control the opening and closing of the opening and closing component 203 according to the sensing signal, so as to realize the opening and closing of the composite panel 101.

[0030] Specifically, the surface aluminum plate 102 and the bottom aluminum plate 104 are bonded to the plastic core layer 103 with an adhesive to form a three-layer structure. The plastic core layer 103 is made of polyvinyl chloride (PVC).

[0031] Furthermore, the frame structure 100 also includes a first conductive coating 105 coated on the surface of the surface aluminum plate 102, and an electromagnetic wave absorber 106 added to the plastic core layer 103.

[0032] The thickness of the surface aluminum plate 102 and the bottom aluminum plate 104 is 0.1 mm to 1.0 mm, and the thickness of the middle plastic core layer is 1 mm to 5 mm. The surface of the surface aluminum plate 102 and the bottom aluminum plate 104 is coated with a conductive coating to enhance the electromagnetic shielding performance.

[0033] Furthermore, the frame structure 100 also includes a second conductive coating 107 coated on the outer surface of the bottom aluminum plate 104, and a conductive sealing strip 108 disposed on the outer surface of the composite plate 101.

[0034] The electromagnetic shielding effectiveness of the composite plate 101 is 30dB to 80dB, and the frequency range is 1MHz to 10GHz. The electromagnetic shielding effect at the joint can be further enhanced by the conductive sealing strip 108 set on the outer surface of the composite plate 101.

[0035] Furthermore, the opening and closing assembly 203 includes a motor 203a adapted to be installed on the outer surface of the door frame 201, and a first pulley 203b fixedly installed on the outer surface of the output end of the motor 203a via a coupling.

[0036] Preferably, the opening and closing assembly 203 further includes a belt 203c sleeved on the outer surface of the first pulley 203b, a second pulley 203d sleeved on the inner surface of the other end of the belt 203c, and a fixing block 203e fixedly installed on the outer surface of the belt 203c.

[0037] It should be noted that the first pulley 203b is rotatably connected to the door frame 201 and a bearing sleeve for rotation is installed at the connection point. The second pulley 203d is rotatably connected to the door frame 201 and a bearing sleeve for rotation is installed at the connection point. The inner surface of the fixing block 203e is in sliding contact with the outer surface of the door frame 201. The fixing block 203e is fixedly connected to the composite plate 101.

[0038] In use, the surface aluminum plate 102 and the bottom aluminum plate 104 are bonded to the plastic core layer 103 with an adhesive to form a three-layer structure. The plastic core layer 103 is made of polyvinyl chloride (PVC) and has lightweight, sound insulation, and heat insulation properties. The surfaces of the surface aluminum plate 102 and the bottom aluminum plate 104 are coated with a conductive coating to improve electromagnetic shielding effectiveness. The conductive sealing strip 108 set at the edge of the composite plate 101 further enhances the electromagnetic shielding effect at the joint. After the detector 202 senses a passing pedestrian, it generates a sensing signal and transmits it to the opening and closing component 203. The motor 203a drives the first pulley 203b, the first pulley 203b drives the belt 203c to rotate, the belt 203c drives the second pulley to rotate, and drives the belt 203c and the fixing block 203e to move, thereby realizing the automatic opening and closing of the composite plate 101.

[0039] In summary, the cooperation between the frame mechanism 100 and the drive mechanism 200 can effectively overcome the shortcomings of traditional electromagnetic shielding materials in terms of flexibility and ease of operation. Especially in places like hospitals and computer rooms where frequent personnel access is required, it can achieve the requirement of rapid opening and closing, which not only enables rapid response of electromagnetic shielding, but also greatly improves the convenience and safety of use.
