[0029] It should be noted that when the GNSS receiver receives a collision, the shock-absorbing structure 5 is provided, and the shock-absorbing plate 501 is pressed by the built-in component box 803 and sleeved on the outer wall of the connecting column 802. When an oscillation occurs, the choke antenna group 6 is supported by the shock-absorbing spring plate 502 at the bottom of the shock-absorbing plate 501, thereby reducing the damage to the choke antenna group 6 caused by the oscillation and achieving a shock-absorbing effect.
[0030] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the heat dissipation structure 3 is arranged inside the built-in cavity 4 and is used to dissipate heat inside the built-in cavity 4. The heat dissipation structure 3 includes a number of heat dissipation holes 301 evenly opened inside the top cover 2, a side mounting ring 302 fixed to the inner wall of the bottom box 1, and a heat conducting plate 303 arranged on the inner wall of the side mounting ring 302. The heat dissipation holes 301 are evenly distributed inside the top cover 2, and the side mounting ring 302 and the heat conducting plate 303 are snap-fitted and connected.
[0031] It should be noted that the circuit will generate heat during daily operation. Excessive heat will cause interference to the circuit. By providing a heat dissipation structure 3, the side mounting ring 302 clamps the heat conducting plate 303 on the top of the built-in component box 803. When the built-in component box 803 is working, heat is generated. The heat is conducted through the built-in component box 803 and reaches the heat dissipation hole 301 at the top of the top cover 2 more quickly and is discharged, thereby playing a role in heat dissipation.
[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the connecting structure 8 includes a connecting groove 801 opened inside the connecting seat 7, a connecting column 802 threadedly connected to the connecting groove 801, and a built-in component box 803 arranged at the top of the connecting column 802.

[0033] It should be noted that when the GNSS receiver with a built-in choke antenna needs to be placed in the desired position, the mounting structure 9 is provided and the mounting base 901 and the mounting column 902 are mounted together by the mounting bolts 903. Only the mounting bolts 903 need to be disassembled to complete the installation and disassembly of the bottom box 1.

[0034] When the present invention is in use, the shock-absorbing plate 501 is pressed by the built-in component box 803 and is sleeved on the outer wall of the connecting column 802. When an oscillation occurs, the choke antenna group 6 is supported by the shock-absorbing spring plate 502 at the bottom of the shock-absorbing plate 501, reducing the damage to the choke antenna group 6 caused by the oscillation. The side mounting ring 302 clamps the heat conducting plate 303 on the top of the built-in component box 803. When the built-in component box 803 is working, heat is generated. The heat is conducted through the built-in component box 803 and reaches the heat dissipation hole 301 at the top of the top cover 2 faster and is discharged. The mounting bolts 903 install the mounting base 901 and the mounting column 902 together. It is only necessary to disassemble and assemble the mounting bolts 903 to complete the installation and disassembly of the bottom box 1. There is no need to directly screw into the bottom box 1, which may easily damage the parts in the built-in cavity 4.
