[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] Example: An external multi-antenna combination antenna, see reference. Figures 1-5 As shown, the device includes an upper cover 1 and a bottom cover 2. The top of the bottom cover 2 is fitted with the upper cover 1. It also includes connecting posts 4, a first PCB board 5, a support post 6, a second PCB board 7, a positioning antenna 8, a first WiFi antenna 9, a second WiFi antenna 10, a first GNSS antenna 11, a second GNSS antenna 12, and an additional mounting structure. The bottom cover 2 has ten evenly spaced mounting holes 3, and the upper cover 1 has ten evenly spaced connecting posts 4. The connecting posts 4 communicate with adjacent mounting holes 3. The upper cover 1 and the bottom cover 2 are assembled by an upper and lower fitting method to form a sealed outer shell structure. The top of the bottom cover 2 is fitted with the first PCB board via bolts. Board 5, ten mounting holes 3 are located around the perimeter of the first PCB board 5, four support pillars 6 are evenly spaced in the middle of the first PCB board 5, a second PCB board 7 is set between the tops of the four support pillars 6, a positioning antenna 8 is set in the middle of the second PCB board 7, first WiFi antennas 9 are set on both the left and right sides of the second PCB board 7, second WiFi antennas 10 are set on both the left and right sides of the second PCB board 7, four first GNSS antennas 11 are evenly spaced on the top of the first PCB board 5, two second GNSS antennas 12 are set on the top of the first PCB board 5, and an antenna mounting structure is provided on the bottom cover 2.
[0021] See Figure 2 , Figure 4 and Figure 5 As shown, the mounting structure includes fixing bolts 15, fixing seat 16 and external threaded sleeve 17. The fixing seat 16 is provided in the middle of the bottom cover 2. Four fixing bolts 15 are threaded between the fixing seat 16 and the bottom cover 2. The external threaded sleeve 17 is provided at the bottom of the fixing seat 16 by welding. Multiple antennas can be combined through the external threaded sleeve 17.
[0022] See Figure 2 , Figure 3 and Figure 5As shown, it also includes a waterproof sealing layer 13 and an annular pressure platform 14. The bottom cover 2 is provided with a waterproof sealing layer 13, the first PCB board 5 is located inside the waterproof sealing layer 13, the top cover 1 is provided with an annular pressure platform 14, and ten connecting columns 4 are located around the annular pressure platform 14.
[0023] See Figure 2 As shown, it also includes a reinforcing rib 18, and the reinforcing rib 18 is fixedly connected between the connecting column 4 and the upper cover 1.
[0024] See Figure 5 As shown, there are multiple heat dissipation holes 19 on the bottom shell.
[0025] See Figure 2 , Figure 3 and Figure 5 As shown, the waterproof sealing layer 13 and the annular pressure plate 14 are shaped to fit together.
[0026] When assembling this device, place the upper cover 1 on the lower cover 2, aligning the mounting holes 3 on the lower cover 2 with the connecting posts 4 on the upper cover 1. Then, use bolts to fix the upper cover 1 and the lower cover 2 together through the mounting holes 3 and the connecting posts 4, so that the upper cover 1 and the lower cover 2 fit together to form a sealed outer shell, providing protection for the internal circuitry. At the same time, the reinforcing ribs 18 prevent the connecting posts 4 from deforming or breaking. In use, the first PCB board 5 serves as the main carrier board, housing four first GNSS antennas 11 and two second GNSS antennas 12, primarily responsible for receiving satellite navigation signals. The second PCB board 7 is suspended above the first PCB board 5 via support columns 6, and centrally mounts the positioning antenna 8, the first WiFi antenna 9, and the second WiFi antenna 1. This design effectively utilizes the internal space, reduces electromagnetic interference between different types of antennas, and enables a compact multi-antenna combination for GNSS positioning and WiFi communication. The heat dissipation holes 19 continuously expel accumulated heat from the shell, effectively controlling the internal operating temperature. When the upper and lower covers are assembled and tightened, the annular pressure plate 14 presses tightly into the waterproof sealing layer 13, effectively preventing the intrusion of moisture, dust, and other contaminants, ensuring stable operation of the internal precision electronic components even in harsh environments. When multiple antennas need to be combined, the fixing seat 16 is first fixed to the bottom cover 2 using the fixing bolts 15, and then the additional antennas are screwed onto the external threaded sleeve 17. This allows for flexible expansion or stacking of multiple antenna units as needed.
