[0003] In the prior art, the antenna radio frequency integrated cavity mostly uses aluminum magnesium alloy material, and then is fixedly combined with the antenna housing by fixing bolts. However, a large number of fixing bolts are used for installation and fixation between the cavity and the antenna housing, resulting in cumbersome disassembly and assembly when maintenance personnel repair and maintain the internal components. A large amount of time is required to disassemble and assemble the fixing bolts, which affects the maintenance efficiency. Content of the Utility Model

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an antenna radio frequency integrated cavity, including: an antenna housing 1; a magnesium alloy cavity 2, the magnesium alloy cavity 2 is arranged on the upper part of the antenna housing 1 for carrying antenna components. Among them, the materials of the magnesium alloy cavity 2 and the antenna housing 1 are aluminum-magnesium alloy material and ABS717 engineering plastic respectively. The combined antenna adopts 4 + 5G, which refers to an antenna system that integrates 4G and 5G antennas. Such an antenna system can support 4G and 5G networks simultaneously, providing a faster and more stable network connection for mobile devices. The design of the combined antenna can improve the signal coverage range, reduce signal interference, increase the data transmission rate, and provide a better network experience for users.

[0022] Multiple sets of limiting components 5, the limiting components 5 are symmetrically distributed on the front and rear sides of the antenna housing 1 and the magnesium alloy cavity 2. Each set of limiting components 5 includes an installation groove 502, and the installation grooves 502 are symmetrically opened on the front and rear sides of the antenna housing 1 and the magnesium alloy cavity 2. Elastic clamping plates 508 are fixedly installed in the middle of the upper installation grooves 502, and limiting notch openings 507 are opened in the lower middle parts of the elastic clamping plates 508. Limiting protrusions 506 are fixedly installed at the bottom ends of the elastic clamping plates 508. Limiting clamping plates 505 are symmetrically and fixedly installed in the lower installation grooves. Limiting pins 509 are slidably installed in the upper parts of the limiting clamping plates 505. Fixed plates 5010 are fixedly installed in the upper parts of the limiting clamping plates 505. Springs 5011 are fixedly installed in the middle of one side of the fixed plates 5010 close to the same-side limiting pins 509. The ends of the springs 5011 away from the fixed plates 5010 are respectively fixedly installed at the ends of the same-side limiting pins 509. Guide grooves 501 are symmetrically opened in the upper installation grooves 502, and limiting holes 504 are opened in the upper parts of the guide grooves 501. Limiting blocks 503 are fixedly installed in the lower parts of the lower installation grooves 502. When the limiting clamping plates 505 are inserted into the installation grooves 502 on the magnesium alloy cavity 2, at this time, the limiting pins 509 will move along the guide grooves 501. And during the movement of the limiting pins 509, the side walls of the guide grooves 501 will squeeze the limiting pins 509, so that the limiting pins 509 will move into the limiting clamping plates 505, and the springs 5011 will be compressed. When the limiting pins 509 are aligned with the limiting holes 504, at this time, the springs 5011 will push the limiting pins 509 into the corresponding limiting holes 504, thereby initially fixing between the magnesium alloy cavity 2 and the antenna housing 1. At the same time, when the lower limiting protrusions 506 of the elastic clamping plates 508 are in contact with the limiting blocks 503, since the limiting blocks 503 and the limiting protrusions 506 are both provided with wedge-shaped surfaces, the elastic clamping plates 508 will deform. When the limiting notch openings 507 on the elastic clamping plates 508 are aligned with the limiting blocks 503, with the cooperation of the self-elastic force of the elastic clamping plates 508, the limiting blocks 503 will be clamped in the corresponding elastic clamping plates 508, thereby completing the secondary limiting between the magnesium alloy cavity 2 and the antenna housing 1, improving the efficiency of the staff to disassemble and assemble the magnesium alloy cavity 2 and the antenna housing 1, simplifying the disassembly and assembly steps, and the limiting pins 509, the limiting holes 504 and the guide grooves 501 are all chamfered. When the staff lifts the elastic clamping plates 508 from the lower part and pulls the antenna housing 1 downward, at this time, the limiting pins 509 will disengage from the limiting holes 504, so as to realize the rapid separation between the magnesium alloy cavity 2 and the antenna housing, facilitating the staff to overhaul and maintain the antenna components inside the antenna housing 1.

[0023] Multiple evenly distributed heat dissipation notches 3 are provided on both the front and rear sides of the magnesium alloy cavity 2. By setting the heat dissipation notches 3, the antenna components inside the magnesium alloy cavity 2 can be cooled in a timely manner, preventing the relevant antenna components from malfunctioning due to uneven heat dissipation. The sides of the limiting block 503 and the limiting protrusion 506 that are away from each other are both wedge-shaped surfaces, and the limiting protrusion 506 and the limiting notch 507 are well-matched. Since the sides of the limiting block 503 and the limiting protrusion 506 that are away from each other are set as wedge-shaped surfaces and the sides close to each other are set as flat surfaces, the wedge-shaped surfaces are conducive to mutual decompression between the two, causing the elastic clamping plate 508 to deform. The flat surfaces can ensure that the limiting block 503 is firmly clamped in the limiting notch 507, preventing the two from separating from each other and resulting in an insecure connection between the magnesium alloy cavity 2 and the antenna housing 1. A number of cross recessed countersunk head screws 4 are provided inside the magnesium alloy cavity 2 for installing antenna components. The antenna components are arranged on the cavity according to performance requirements in sequence. 54 aluminum alloy cross recessed countersunk head screws 4 with the model of M3*8 are used to directly fix the antenna on the magnesium alloy cavity 2, effectively shielding the penetration of radio frequency signals into the magnesium alloy cavity 2 and making the product more stable. The end faces of the elastic clamping plate 508 and the limiting clamping plate 505 are flush with the surfaces of the antenna housing 1 and the magnesium alloy cavity 2. The elastic clamping plate 508 and the limiting clamping plate 505 are both arranged in the installation groove 502 and are flush with the magnesium alloy cavity 2 and the antenna housing 1. Cooperating with the guiding groove 501, it is convenient for the staff to disassemble and assemble the magnesium alloy cavity 2 and the antenna housing 1 without misalignment, further improving the convenience of installation between the magnesium alloy cavity 2 and the antenna housing 1.

[0024] Although the above describes the illustrative specific embodiments of the present application for the understanding of those skilled in the art of the present technology, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of the present technology, as long as all changes are within the spirit and scope of the present application defined and determined by the appended claims, all application creations using the concept of the present application are within the scope of protection.
