[0043] To address the assembly difficulties of existing portable broadband wireless devices and improve production efficiency, this utility model provides a portable broadband wireless device. Figures 1 to 9 A preferred embodiment of the portable broadband wireless device provided by this utility model is shown.

[0044] Please see Figure 1 and Figure 2 In this embodiment, the portable broadband wireless device 1000 includes an antenna assembly 100, a circuit board assembly 200, and a battery assembly 300.

[0045] Specifically, the portable broadband wireless device 1000 adopts a modular structure design, divided into three independently assembleable modular components: an antenna assembly 100, a circuit board assembly 200, and a battery assembly 300. The antenna assembly 100 includes an antenna 110, the circuit board assembly 200 includes a circuit board 210, and the battery assembly 300 includes a battery 310.

The first fasteners 400 and second fasteners 500 can be screws or rivets, etc. The following description will use an example where both the first fastener 400 and second fastener 500 are screws.

[0047] The portable broadband wireless device 1000 of this utility model adopts a modular design, which allows the antenna assembly 100, circuit board assembly 200, and battery assembly 300 to be assembled separately and independently. Then, the circuit board assembly 200 is fixedly assembled to the antenna assembly 100 using the first fastener 400. Finally, the battery assembly 300 is fixedly assembled to the circuit board assembly 200 using the second fastener 500, thereby forming a complete portable broadband wireless device 1000. This simplifies the assembly of complex parts, which on the one hand facilitates the assembly of the portable broadband wireless device 1000 and improves production efficiency, and on the other hand, the antenna 110, circuit board 210, and battery 310 are integrated into one unit and can be independently powered on and tested, thereby improving production and testing efficiency and reducing production costs.

[0049] Specifically, the antenna bracket 120 serves as the carrier of the antenna 110, and the circuit board assembly 200 is also fixed to the antenna bracket 120, thus allowing the connection structure between the antenna assembly 100 and the circuit board assembly 200 to be set on the antenna bracket 120. Similarly, the battery bracket 320 serves as the carrier of the battery 310, and the battery assembly 300 is also fixed to the circuit board assembly 200 via the battery bracket 320, thus allowing the connection structure between the circuit board assembly 200 and the battery assembly 300 to be set on the battery bracket 320.

Finally, the first fastener 400 is used to fix the circuit board assembly 200 onto the antenna bracket 120. This arrangement of the first fastening portion 211 and the first snap-fit ​​portion 121 makes the assembly of the antenna assembly 100 and the circuit board assembly 200 simpler and easier.

Finally, the second fastener 500 is used to fix the battery component 300 onto the circuit board assembly 200. This arrangement of the second latching part 321 and the second snap-fit ​​part 122 makes the assembly of the circuit board assembly 200 and the battery component 300 simpler and easier.

[0054] The circuit board assembly 200 is fixed to the antenna bracket 120 by the first fastener 400. The specific position of the circuit board assembly 200 on the antenna bracket 120 can be set according to the actual situation.

Furthermore, the shape of the battery bracket 320 is also usually adapted to the shape of the first mounting groove 123, with the lower end of the battery bracket 320 extending into the first mounting groove 123 from the opening. This arrangement of the first mounting groove 123 on the antenna bracket 120 not only helps to reduce the thickness of the portable broadband wireless device 1000 but also enables the mounting and positioning of the circuit board assembly 200 and the battery assembly 300 on the antenna bracket 120. The bottom wall of the first mounting groove 123 is usually provided with a first through hole 127.

[0056] The antenna bracket 120 and the circuit board assembly 200 are respectively provided with a first snap-fit ​​part 121 and a first fastening part 211.

The first latching protrusions 121a abut against the upper side of the edge of the circuit board 210, thereby limiting the circuit board 210 vertically and upwardly through the first latching protrusions 121a and the bottom wall of the first mounting groove 123. Thus, the first latching protrusions 121a and the edge of the circuit board 210 respectively constitute the first latching part 121 and the first fastening part 211. This arrangement of the first latching part 121 and the first fastening part 211 is relatively simple.
