Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic communication signal shielding equipment, in particular to a mobile phone signal shielding device. Background Art
[0002] To maintain safety, order, and privacy, signal shielding devices are installed in certain locations (such as examination halls, party and government offices, and confidential meetings) to block communications between mobile phones and base stations. Currently, the core operating principle of commonly used signal shielding devices is to emit electromagnetic waves of a specific frequency to interfere with the transmission of mobile phone signals. This device uses techniques such as frequency multiplication, frequency division, and frequency hopping filtering to analyze the required shielding frequency and then create a shielding magnetic field within a specified range. However, this method involves a wide range and can easily cause unnecessary interference to surrounding communications, making it only suitable for large-scale shielding scenarios.
[0003] To achieve more precise shielding, physical isolation technology can also be used to shield mobile phone signals. This technology utilizes a physical structure, such as a shielding cover made of metal or special materials, to isolate the phone from external electromagnetic waves. For example, Chinese utility model patent document (CN209489104U) discloses a mobile phone signal shielding bag. This bag utilizes a double layer of conductive shielding fabric sewn together to form a pocket with an open top. The seams are sealed with hot-melt adhesive using a hemming machine. However, this bag can accommodate only a small number of mobile phones at a time, making individual monitoring difficult. Utility Model Content
[0004] The utility model provides a mobile phone signal shielding device to solve the problem of wide radiation range of signal shielding equipment in the prior art.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is to provide a mobile phone signal isolator, which includes a housing, a base and a plurality of partitions.
[0006] The housing includes a fixed housing and a movable housing, the surfaces of the fixed housing and the movable housing are coated with a metal coating, wherein the movable housing can slide relative to the fixed housing to form an opening;
[0007] The base is connected to the fixed shell to form a shielded chamber capable of accommodating a mobile battery, wherein the surface of the base is coated with the metal coating; a plurality of partitions are located in the shielded chamber and are spaced apart on the base along a first direction to form a limited space for placing the mobile phone.
[0008] The technical solution provided by this utility model has the following beneficial effects compared with the prior art:
[0009] By applying a metal coating to the housing and base, the two reflect and absorb electromagnetic waves, blocking the mobile phone's ability to receive and transmit information. Together, the housing and base create a shielded chamber, effectively creating a Faraday cage. This constant reflection and absorption significantly weakens or even degrades the signal strength of the mobile device within.
[0010] The movable housing forms an opening relative to the fixed housing that communicates with the internal shielded chamber, allowing users to easily access their mobile phones. Furthermore, multiple partitions can orderly arrange the mobile phones within the shielded chamber, reducing friction and interference between the mobile phones and making it easier for users to claim their mobile phones.
[0011] Compared with the current signal shielding by emitting specific electromagnetic waves, the above-mentioned physical isolation has higher accuracy and can effectively avoid interference with surrounding communications. It also has a simple structure, low manufacturing cost, and can be flexibly used in a variety of usage scenarios.
[0012] In some embodiments, the base further includes a plurality of wireless charging plates arranged parallel to the partitions, wherein the wireless charging plates are located between two adjacent partitions along the first direction, so that the confined space is divided into a first confined space and a second confined space.
[0013] The above technical solution, by equipping the base with a wireless charging pad, allows mobile phones to be charged even when shielded. In addition, the wireless charging pad does not require an additional charging cable and is compatible with a variety of mobile phone brands.
[0014] In some embodiments, a plurality of the wireless charging pads are provided with a protrusion along the first direction on one side facing the second limited space.
[0015] With the above technical solution, when the wireless charging plate is not provided with a protrusion, the mobile phone can be placed in the first limited space and the second limited space respectively. However, since the battery will have a thermal effect during the wireless charging process, adding a protrusion can isolate the mobile phone and increase the heat dissipation space.
[0016] In some embodiments, the base further includes a circuit board and a power interface for connecting to an external power supply. The circuit board is embedded in the base and electrically connected to the wireless charging pad, thereby achieving integrated power management and reducing external wiring.
[0017] In some embodiments, a ring groove is provided at the connection between the base and the fixed shell, wherein a sealing ring is embedded in the outer edge of the ring groove to avoid electromagnetic leakage at the connection.
[0018] In some embodiments, the fixed shell and the movable shell form a hemispherical shape.
[0019] By adopting the above technical solution, the hemispherical design makes it both beautiful and practical, and when multiple mobile phones need to be placed, the space of the shielding chamber can be maximized.
[0020] In some embodiments, an LED light module is provided in the shielding chamber, the LED light module is electrically connected to the circuit board, and is symmetrically located on both sides of the fixed shell along the first direction. The LED light module is additionally provided to illuminate the shielding chamber.
[0021] In some embodiments, the inner side of the fixed housing is further provided with a plurality of slide grooves, and the movable housing is provided with sliders that can fit into the grooves. The sliders and the slide grooves guide the movable housing to slide into the interior of the fixed housing, thereby forming an opening for the user to place or take out the mobile phone.
[0022] In some embodiments, the outer periphery of the base is further provided with a plurality of USB ports, which can be connected to external circuits to achieve multi-circuit power input and output.
[0023] In some embodiments, a switch button is further provided on the outer peripheral side of the base. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0035] See also Figures 1 to 2 As shown, Figure 1 The three-dimensional structure diagram of an embodiment of a mobile phone signal blocker provided by the present application is shown. Figure 1 ; Figure 2 The three-dimensional structure diagram of an embodiment of a mobile phone signal blocker provided by the present application is shown. Figure 2 .
[0036] In some embodiments, the mobile phone signal isolator includes: a housing 10, a base 20, and a plurality of partitions 30. The housing 10 includes a fixed housing 11 and a movable housing 12, the surfaces of the fixed housing 11 and the movable housing 12 being coated with a metal coating, wherein the movable housing 12 can slide relative to the fixed housing 11 to form an opening 13.
[0037] The base 20 is connected to the fixed housing 11 to form a shielding chamber 21 capable of accommodating the mobile battery, wherein the surface of the base 20 is coated with a metal coating; a plurality of partitions 30 are located in the shielding chamber 21 and are arranged along a first direction ( Figure 1 The two brackets 32 are spaced apart from each other in the base 20 to form a limited space 31 for placing a mobile phone 40.
[0038] In the embodiment of the present application, a metal coating is applied to the surfaces of the housing 10 and base 20, enabling the housing 10 and base 20 to reflect and absorb electromagnetic waves, thereby blocking information reception and transmission by the mobile phone 40. Specifically, when the housing 10 and base 20 together enclose a shielding chamber 21, they act as a Faraday cage, significantly weakening or even reducing the signal strength of the mobile device within through continuous reflection and absorption. Exemplarily, the metal coating may be a nickel-based electromagnetic wave shielding composite coating, copper or aluminum metal particle conductive coating, or the like, though this application does not limit this.
[0039] The movable housing 12 can form an opening 13 relative to the fixed housing 11 that communicates with the internal shielded chamber 21, allowing the user to easily access the mobile phone 40. For example, the curvature of the movable housing 12 is greater than the curvature of the fixed housing 11, and the arc length of the movable housing 12 is less than the arc length of the fixed housing 11, so that the movable housing 12 can be completely slidably embedded in the fixed housing 11.
[0040] Furthermore, the multiple partitions 30 can orderly arrange the mobile phones 40 within the shielding chamber 21, reducing friction and interference between the mobile phones 40 and making it easier for users to claim the mobile phones 40. In some application scenarios, such as conference rooms, the mobile phone 40 shield can be directly deployed, allowing participants to place their mobile phones 40 in the limited spaces 31 of the partitions 30 and easily claim them after the meeting.
[0041] In some embodiments, the base 20 also includes a circuit board (not shown in the figure) and a power interface 23 for connecting to an external power supply. The circuit board is embedded in the base 20 and electrically connected to the wireless charging plate 22, thereby realizing integrated power management and reducing external wiring.
[0042] In some embodiments, the outer periphery of the base 20 is further provided with a plurality of USB ports 26. The plurality of USB ports can be connected to external circuits, thereby realizing multi-circuit power input and output.
[0043] In some embodiments, the fixed housing 11 and the movable housing 12 form a hemispherical shape.
[0044] In the embodiment of the present application, the hemispherical design makes it both aesthetically pleasing and practical. When multiple mobile phones 40 need to be placed, the space of the shielding chamber 21 can be maximized. For example, the bottom of the movable housing 12 is further provided with a boss 121, which facilitates the user to open and close the shielding chamber 21 through the boss 121.
[0045] See also Figure 3 As shown, Figure 3 The three-dimensional structure diagram of an embodiment of a mobile phone signal blocker provided by the present application is shown. Figure 3 .
[0046] In some embodiments, the base 20 further includes a plurality of wireless charging pads 22 arranged parallel to the partition 30, wherein the wireless charging pads 22 are arranged along the first direction ( Figure 1 The first limiting space 310 is located between two adjacent partitions 30, so that the limiting space 31 is divided into a first limiting space 310 and a second limiting space 311.
[0047] In the embodiment of the present application, the base 20 is equipped with a wireless charging pad 22, so that the mobile phone 40 can be charged while being shielded. The wireless charging pad 22 does not require an additional charging cable and can be adapted to mobile phones 40 of various brands.
[0048] Exemplarily, the height of the partition 30 is smaller than that of the wireless charging plate 22 , so that one side of the battery of the mobile phone 40 can be in contact with the wireless charging plate 22 for charging, while one side of the partition 30 can be easily picked up by the user.
[0049] In some embodiments, a switch button 27 is further provided on the outer periphery of the base 20 .
[0050] See also Figure 4 As shown, Figure 4 FIG2 shows a schematic diagram of the three-dimensional structure of a base 20 of a mobile phone signal isolator provided by the present application.
[0051] In some embodiments, the plurality of wireless charging pads 22 are arranged along a first direction ( Figure 1 A protrusion 220 is provided on one side (as shown in the X direction) facing the second limiting space 311.
[0052] In some application scenarios, when the wireless charging plate 22 is not provided with the protrusion 220, the mobile phone 40 can be placed in the first limited space 310 and the second limited space 311 respectively. In other application scenarios, since the battery will have a thermal effect during wireless charging, adding the protrusion 220 can isolate the distance between the mobile phones 40 and increase the heat dissipation space. For example, in combination Figures 3 and 4 As shown, the first limiting space 310 is used to place the mobile phone 40 , and the protrusion 220 extends to the second limiting space 311 .
[0053] In some embodiments, combined Figure 2 and 4 As shown, a ring groove 24 is provided at the connection between the base 20 and the fixed housing 11 , wherein a sealing ring 25 is embedded in the outer edge of the ring groove 24 , thereby enhancing the sealing performance of the shielding chamber 21 to avoid electromagnetic leakage at the connection.
[0054] In some embodiments, the shielding chamber 21 is provided with an LED lamp module 110, which is electrically connected to the circuit board and arranged along a first direction ( Figure 1 The LED light modules 110 are symmetrically located on both sides of the fixed housing 11 (as shown in the X direction) to illuminate the shielding chamber 21.
[0055] See also Figure 5 As shown, Figure 5 FIG2 shows a schematic diagram of the three-dimensional structure of a housing 10 of a mobile phone signal isolator provided by the present application.
[0056] In some embodiments, the inner side of the fixed housing 11 is further provided with a plurality of slide grooves 111, and the movable housing 12 is provided with a slider 120 that can cooperate with the slide grooves 111 in a concave-convex manner. The slider 120 and the slide groove 111 are used to guide the movable housing 12 to slide into the interior of the fixed housing 11, thereby forming an opening 13 for the user to place or take out the mobile phone 40. Exemplarily, the fixed housing 11 is further provided with a support member 112 to improve its durability. When the movable housing 12 slides into the fixed housing 11, the support member 112 can also serve to limit the embedding length of the movable housing 12, so that when there is no external force, the movable housing 12 can automatically close the shielding chamber 21 under the action of gravity.
