Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone antenna technology, and in particular to a 5G mobile phone antenna with anti-interference function. Background Technology
[0002] A 5G mobile phone antenna is a key component for receiving and transmitting 5G signals; essentially, it is a transducer that converts electrical signals into electromagnetic waves. Compared to 4G antennas, 5G antennas have significant upgrades in frequency band, structure, and performance to meet the demands of 5G networks for high speed, low latency, and massive connectivity.
[0003] To address this, patent CN217589425U discloses a 5G mobile phone antenna structure, including a square ring, a backing plate mounted on the rear side of the square ring, a heat dissipation sheet mounted in the middle of the backing plate, a heat-conducting sheet mounted on the rear side of the heat dissipation sheet, an antenna sheet pressed between the heat-conducting sheet and the heat dissipation sheet, a rubber ring penetrating the middle of the antenna sheet, and a heat insulation frame sleeved on the outer front part of the rubber ring. This utility model, through its overall structural design, uses a heat insulation frame and rubber ring sleeved on the outside of the camera for heat insulation, and the antenna sleeved on the outside of the camera. It employs a clamp-on double-sided heat dissipation and sidewall heat conduction method to increase the contact area between the heat dissipation structure and the antenna, thereby increasing the speed of heat conduction. Furthermore, the sheet-like heat dissipation sheet structure quickly disperses heat throughout the entire structure, increasing the contact area with the outside and enabling rapid heat dissipation, thus mitigating the impact of heat generation on the camera.
[0004] The existing technical solutions mentioned above have the following drawbacks: although they can dissipate heat and cool the antenna sheet, they are not convenient for quick and easy antenna assembly, thus affecting the efficiency of assembling the mobile phone substrate and the antenna sheet. Utility Model Content
[0005] The purpose of this invention is to provide a 5G mobile phone antenna with anti-interference function to solve the problem of the inconvenience and inefficiency in assembling existing 5G mobile phone antennas.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a 5G mobile phone antenna with anti-interference function, including a mobile phone substrate;
[0007] An assembly mechanism is installed on the outer wall of the mobile phone substrate;
[0008] The assembly mechanism includes an assembly frame fixedly installed on one side of the mobile phone substrate. The assembly frame has a slot inside and a movable groove inside. The inner bottom wall of the movable groove has a guide groove. A locking block is movably connected inside the movable groove. A guide block is fixedly connected to the bottom of the locking block. A return spring is fixedly connected to the outer wall of the locking block. An antenna piece is installed inside the assembly frame.
[0009] Preferably, the antenna sheet has a slot inside, and heat dissipation fins are fixedly connected to the outer wall of the antenna sheet to facilitate heat dissipation of the antenna sheet.
[0010] Preferably, the assembly frame forms a sliding structure with the movable groove and the locking block, and the assembly frame forms a sliding structure with the guide groove and the guide block, so that the locking block can slide along the movable groove and be stored in the assembly frame.
[0011] Preferably, the card block is engaged with the antenna piece via a card slot, and the card slot is symmetrically arranged with respect to the central axis of the antenna piece, so that the end of the card block can be engaged into the card slot for positioning.
[0012] Preferably, the mounting bracket is connected to the antenna piece via a slot, and the mounting bracket is U-shaped to facilitate the installation of the antenna piece.
[0013] Preferably, a low dielectric constant foam dielectric layer is fixedly connected to the outer wall of the antenna sheet, a carbonyl iron particle-filled silicone rubber layer is fixedly connected to the outer wall of the low dielectric constant foam dielectric layer, and a graphene coating is fixedly connected to the outer wall of the carbonyl iron particle-filled silicone rubber layer.
[0014] Preferably, the low dielectric constant foam dielectric layer and the carbonyl iron particle-filled silicone rubber layer are tightly bonded together, and the carbonyl iron particle-filled silicone rubber layer is arranged parallel to the graphene coating, which can improve the anti-interference performance of the antenna sheet.
[0015] The present invention provides a 5G mobile phone antenna with anti-interference function, the advantages of which are:
[0016] The mobile phone base plate, assembly mechanism, antenna piece, card slot and heat dissipation fins are set up. By moving the antenna piece, it is inserted into the slot opened inside the assembly frame. The card block slides along the movable slot and is put into the assembly frame. When the antenna piece is fully inserted into the slot, under the action of the return spring, one end of the card block can be inserted into the card slot for limiting, which facilitates the assembly and connection of the antenna piece and the mobile phone base plate.
[0017] Furthermore, the combined action of the guide block and the guide groove can improve the stability of the sliding of the locking block and further improve the stability of the antenna piece's positioning.
[0018] Furthermore, the heat dissipation fins facilitate the dissipation of heat generated during the operation of the antenna.
[0019] The device consists of a mobile phone substrate, a low dielectric constant foam dielectric layer, a carbonyl iron particle-filled silicone rubber layer, and a graphene coating. The low dielectric constant foam dielectric layer is fixedly connected to the outer wall of the mobile phone substrate. The porous structure of the foam in the low dielectric constant foam dielectric layer can enhance the scattering and diffraction of electromagnetic waves inside the material, extend the propagation path, and improve the absorption efficiency in the mid-to-high frequency band. The carbonyl iron particle-filled silicone rubber layer is fixedly connected to the outer wall of the low dielectric constant foam dielectric layer. The flexibility of the silicone rubber can adapt to the bending scenario of the mobile phone. At the same time, its dielectric constant forms a gradient transition with the low dielectric foam, optimizes impedance matching, and improves the anti-interference performance of the antenna sheet.
[0020] Furthermore, a graphene coating is fixedly connected to the outer wall of the silicone rubber layer filled with carbonyl iron particles. Since the resistive loss of graphene can absorb millimeter wave interference in the 24-40GHz range, the reflection loss of the multi-layer graphene stacked in the 28GHz band reaches -25dB, which further improves the anti-interference performance of the antenna sheet.

[0028] Please see Figures 1-5 The present invention provides a 5G mobile phone antenna with anti-interference function, including a mobile phone substrate 1.
[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an assembly mechanism 2 is installed on the outer wall of the mobile phone substrate 1. The assembly mechanism 2 includes an assembly frame 21 fixedly installed on one side of the mobile phone substrate 1. The assembly frame 21 has a slot 22 and a movable groove 23 inside. The inner bottom wall of the movable groove 23 has a guide groove 24. A locking block 25 is movably connected inside the movable groove 23. A guide block 26 is fixedly connected to the bottom of the locking block 25. A return spring 27 is fixedly connected to the outer wall of the locking block 25. An antenna piece 3 is installed inside the assembly frame 21. A slot 4 is opened inside the antenna piece 3. A heat dissipation fin 5 is fixedly connected to the outer wall of the antenna piece 3. The assembly frame 21 forms a sliding structure with the locking block 25 through the movable groove 23. The assembly frame 21 forms a sliding structure with the guide block 26 through the guide groove 24. The locking block 25 is engaged with the antenna piece 3 through the slot 4. The slot 4 is symmetrically arranged around the central axis of the antenna piece 3. The assembly frame 21 is engaged with the antenna piece 3 through the slot 22. The assembly frame 21 is U-shaped.
[0030] By moving the antenna piece 3, it is inserted into the slot 22 inside the assembly frame 21, causing the outer wall of the antenna piece 3 to press against the locking block 25. The locking block 25 slides along the movable groove 23 and is retracted into the assembly frame 21. The guide block 26 slides along the guide groove 24, causing the locking block 25 to press against the reset spring 27. When the antenna piece 3 is fully inserted into the slot 22, the locking block 25 can slide back along the movable groove 23 under the action of the reset spring 27, and one end of the locking block 25 is inserted into the slot 4 for limiting, so that the antenna piece 3 is installed on the mobile phone base plate 1.
[0031] Reference Figure 1 and Figure 5 As shown, a low dielectric constant foam dielectric layer 6 is fixedly connected to the outer wall of the antenna sheet 3. A carbonyl iron particle-filled silicone rubber layer 7 is fixedly connected to the outer wall of the low dielectric constant foam dielectric layer 6. A graphene coating 8 is fixedly connected to the outer wall of the carbonyl iron particle-filled silicone rubber layer 7. The low dielectric constant foam dielectric layer 6 and the carbonyl iron particle-filled silicone rubber layer 7 are tightly bonded together, and the carbonyl iron particle-filled silicone rubber layer 7 and the graphene coating 8 are arranged in parallel.
[0032] A low-dielectric-constant foam dielectric layer 6 is fixedly connected to the outer wall of the mobile phone substrate 1. The porous structure of the foam in the low-dielectric-constant foam dielectric layer 6 can enhance the scattering and diffraction of electromagnetic waves inside the material, extend the propagation path, and improve the absorption efficiency in the mid-to-high frequency band, such as 6-40GHz, thus achieving an anti-interference effect. Since a carbonyl iron particle-filled silicone rubber layer 7 is fixedly connected to the outer wall of the low-dielectric-constant foam dielectric layer 6, the flexible properties of silicone rubber can adapt to the bending scenario of the mobile phone. At the same time, its dielectric constant forms a gradient transition with the low-dielectric foam, optimizing impedance matching and further improving the anti-interference performance. A graphene coating 8 is fixedly connected to the outer wall of the carbonyl iron particle-filled silicone rubber layer 7. Since the resistivity loss surface resistance of graphene is 50-100Ω / sq, it can absorb 24-40GHz millimeter wave interference. Multi-layer graphene stacking, such as 10 layers, achieves a reflection loss of -25dB in the 28GHz band, further reducing the interference received by the antenna sheet 3.
