Description

Technical Field

[0001] This utility model relates to the field of wireless communication antenna technology, and in particular to a waterproof 5G mushroom-shaped antenna. Background Technology

[0002] With the rapid development and widespread application of fifth-generation mobile communication technology, the performance requirements of communication equipment for antennas are increasing, especially in terms of signal coverage, multi-band compatibility, and environmental adaptability. Mushroom-shaped antennas, due to their compact structure, convenient installation, symmetrical radiation pattern, and good vertical polarization characteristics, are widely used in outdoor scenarios such as vehicle communication systems, mobile base stations, traffic signal control, energy facility monitoring, and industrial IoT terminals. Especially in applications requiring highly reliable wireless connections, this type of antenna has become one of the mainstream choices.

[0003] However, traditional mushroom-shaped antennas face many challenges in practical use, especially in terms of environmental adaptability and long-term sealing reliability. Existing products usually use the method of connecting the upper and lower covers and fastening them with screws to achieve shell encapsulation. However, during the assembly process, the screw fastening method can easily create local gaps between the upper and lower covers. When these gaps are exposed to harsh environmental conditions such as rain, snow, high humidity, salt spray, and temperature fluctuations for a long time, external moisture will gradually penetrate into the antenna, causing signal attenuation, short circuits, or even equipment damage, which seriously affects communication stability and equipment lifespan.

[0004] Therefore, there is an urgent need to provide a waterproof 5G mushroom-shaped antenna, which improves assembly sealing by designing a multi-layer waterproof ring structure. Utility Model Content

[0005] In order to overcome the shortcomings of existing mushroom-shaped antennas, such as the easy formation of gaps at the joint between the upper and lower covers leading to moisture intrusion, poor sealing reliability, and insufficient waterproof performance in outdoor applications, this utility model provides a waterproof 5G mushroom-shaped antenna.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a waterproof 5G mushroom-shaped antenna, comprising a lower cover and an upper cover, wherein the lower cover and the upper cover are assembled by an upper and lower fitting method to form a sealed outer shell structure. Multiple mounting holes are evenly distributed circumferentially along the edge of the lower cover. Multiple connecting posts are evenly distributed circumferentially inside the upper cover, with the positions of the connecting posts corresponding one-to-one with the mounting holes on the lower cover. Multiple support posts are evenly distributed circumferentially inside the lower cover. Multiple copper studs are evenly distributed circumferentially at the center of the lower cover, with a PCB board fixedly mounted at the top of each copper stud. Multiple support seats are evenly distributed circumferentially at the center of the lower cover, with a GNSS antenna fixedly mounted on each support seat. Multiple 5G antenna radiators are evenly distributed circumferentially along the edge of the PCB board. The lower cover is provided with an outer waterproof ring, and an inner waterproof ring is provided within the outer waterproof ring, forming a sealed interlayer between the outer and inner waterproof rings. An annular pressure platform is provided at the bottom of the upper cover in conjunction with the sealing clamp.

[0007] Optionally, the outer waterproof ring and the inner waterproof ring are made of rubber.

[0008] Optionally, a fixing seat is fixedly provided at the bottom of the lower cover, and an external threaded sleeve is provided on the fixing seat.

[0009] Optionally, a heat dissipation hole is provided at the center of the lower cover.

[0010] Optionally, a first reinforcing rib is provided between each of the connecting columns and the top cover.

[0011] Optionally, the annular pressure platform is provided with a plurality of second reinforcing ribs arranged in a ring at uniform intervals inside.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting an outer waterproof ring and an inner waterproof ring on the lower cover to form an annular sealing interlayer, and cooperating with the annular pressure plate at the bottom of the upper cover to be embedded in the interlayer, a double compression sealing structure is formed, thereby significantly improving the dustproof and waterproof capabilities at the joints, so that the overall protection level of the machine can reach the IP68 standard.

[0013] 2. The bottom of the cover has an external threaded sleeve that can be screwed directly into the equipment mounting hole for quick and secure mechanical fixing and electrical grounding. It supports modular installation and quick replacement, improving on-site deployment efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-5A waterproof 5G mushroom-shaped antenna includes a lower cover 1 and an upper cover 2. The lower cover 1 and the upper cover 2 are assembled by fitting together to form a sealed outer shell structure. A heat dissipation hole 16 is provided at the center of the lower cover 1, which forms convection heat dissipation with the outside air, effectively reducing the internal temperature rise of the cavity, preventing material aging, signal distortion or performance degradation due to overheating, and improving the thermal stability and long-term operational reliability of the device. Eight mounting holes 3 are evenly distributed around the edge of the lower cover 1, and the upper cover 2 has eight mounting holes 3 evenly distributed around the edge. There are eight connecting posts 4, each corresponding to a mounting hole 3 on the lower cover 1, used to engage with screws to lock and fix the upper and lower covers 1. Four support posts 5 are evenly arranged circumferentially inside the lower cover 1, and four copper studs 6 are evenly arranged circumferentially at the center of the lower cover 1. A PCB board 7 is fixedly mounted on the top of each copper stud 6. The PCB board 7 is electrically grounded and mechanically fixed via the copper studs 6, while the outer support posts 5 provide auxiliary support, forming a composite support structure that effectively improves the PCB board's stability. To ensure the installation stability of board B7 and prevent loosening or breakage due to vibration or impact, four support bases 8 are evenly arranged circumferentially at the center of the lower cover 1. These support bases 8 collectively fix a GNSS antenna 9. Eight 5G antenna radiators 10 are evenly arranged circumferentially along the edge of the PCB board 7 to achieve multi-band signal coverage. The lower cover 1 is provided with an outer waterproof ring 11, and an inner waterproof ring 12 is provided within the outer waterproof ring 11. A sealed interlayer is formed between the outer waterproof ring 11 and the inner waterproof ring 12. Furthermore, ... The outer waterproof ring 11 and the inner waterproof ring 12 are made of rubber material with high elasticity and aging resistance, and have good compression resilience and environmental resistance. The bottom of the upper cover 2 is provided with an annular pressure platform 13 that cooperates with the sealing clamp. Each connecting column 4 is provided with a first reinforcing rib 17 between itself and the upper cover 2 to enhance the bending strength and torsional stiffness of the connecting column 4. The annular pressure platform 13 is provided with eight second reinforcing ribs 18 arranged in a ring at even intervals inside to enhance the overall rigidity and load-bearing capacity of the annular pressure platform 13.

[0022] During the production and assembly of this device, the PCB board 7 is first fitted onto the copper studs 6 and fixed by nuts or welding. At the same time, the circumferentially distributed support columns 5 provide bottom support to ensure that the PCB board 7 is horizontal and stable. Then, the GNSS antenna 9 module is installed on the support base 8 and electrically connected to the PCB board 7 by wires. The 5G antenna radiator 10, as a printed patch or independent radiating unit on the PCB, has been integrated into the PCB design to complete the overall circuit layout. Then, the upper cover 2 is aligned with the lower cover 1 and fitted together, so that the annular pressure plate 13 at the bottom of the upper cover 2 is embedded in the sealing interlayer between the outer waterproof ring 11 and the inner waterproof ring 12 of the lower cover 1. This structure forms a double sealing protection, effectively preventing moisture and liquid from entering from the joint, thus improving the protection level of the whole device. Finally, by inserting screws through the mounting holes 3 of the lower cover 1 and screwing them into the connecting columns 4 on the inside of the upper cover 2, the upper and lower covers 1 are firmly locked.

[0023] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 The bottom of the lower cover 1 is fixedly provided with a fixing seat 14, and the fixing seat 14 is provided with an external threaded sleeve 15. The metal sleeve is used to connect with the mounting hole 3 of the external equipment to achieve stable installation and quick disassembly of the antenna.

[0024] When installing the entire device, the antenna can be screwed into the mounting interface of the vehicle terminal, communication chassis, or rod bracket. The external threaded sleeve 15 is gradually screwed into the internal threaded mounting hole 3 on the equipment to achieve axial compression and circumferential fixation. During the tightening process, a tight threaded fit is formed between the sleeve and the mounting hole 3, which effectively resists vibration and loosening. When it is necessary to replace or repair the antenna, the entire antenna can be removed by simply rotating it in the opposite direction without disassembling the internal structure of the equipment, thus achieving quick replacement and modular maintenance.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
