Abstract: An outdoor electronic apparatus and a sunshade thereof are provided. The sunshade is assembled to an electronic device, and includes a top shield and a plurality of shielding structures formed on the top shield. The top shield has a plurality of top convection holes at least partially corresponding in position to the shielding structures. An edge of any one of the shielding structures and a hole edge of the corresponding top convection hole jointly define a first interface region having an outflow area. The sunshade and an outer surface of the electronic device jointly define a second interface region that is in spatial communication with the first interface regions of the top shield and that has an inflow area. The inflow area is greater than or equal to at least 20% of a sum of the outflow areas of the top shield.

Abstract: A bridging mechanism, for connecting a supporting tube and a holder, includes at least one positioning portion, a bridging member, a connecting member, a handle and at least one positioning structure. The at least one positioning portion is formed on the supporting tube. The bridging member is used for bridging the supporting tube. The connecting member extends from the bridging member for connecting the holder. The handle is pivoted to the bridging member for rotably pressing the supporting tube when the supporting tube is bridged to the bridging member, so as to abut the supporting tube against the bridging member. The at least one positioning structure is formed on the handle. The at least one positioning structure simultaneously rotates with the handle for wedging with the at least one positioning portion when the handle rotates to press the supporting tube to position the bridging member on the supporting tube.

Abstract: A screw mechanism for adjusting an angle of an antenna module is disclosed in the present invention. The screw mechanism includes a screw rod. The screw rod includes a rod portion. A thread is formed on a first area of the rod portion. An annular protrusion is formed on a second area of the rod portion, and an outer diameter of the annular protrusion is greater than an outer diameter of the rod portion. The screw rod further includes a handle disposed on an end of the rod portion adjacent to the second area. The screw mechanism further includes an accommodating component whereon a sunken part is formed. The sunken part is for accommodating the annular protrusion of the screw rod. The screw mechanism further includes a screw having a side hole. The screw is installed on the first area of the screw rod and moves along the thread.

Abstract: A clamping mechanism includes a clamping member, a first fixing member, a second fixing member, a shaft, a first adjusting member, a second adjusting member and a handle. The clamping member encloses a supporting tube. The first fixing member and the second fixing member are connected to the clamping member, respectively. The shaft is disposed through the first fixing member and the second fixing member. The first adjusting member, connected to the shaft, abuts against the first fixing member. The second adjusting member, connected to the shaft, cooperates with the first adjusting member for driving the second fixing member to move relative to the first fixing member along the shaft. The handle, pivoted to the second fixing member, abuts against the second fixing member for pressing the second fixing member to approach the first fixing member, so as to force the clamping member to clamp the supporting tube.

Abstract: A supporting pedestal capable of adjusting an azimuth angle of an antenna system is disclosed in the present invention. The angle adjusting mechanism includes a main body and a tube. The main body includes a base, a first board and a second board. The first board and the second board are respectively disposed on two sides of the base. A first pivot hole and a first slot are formed on the first board. A second pivot hole is formed on the second board. The main body further includes a strengthening rib disposed on an edge of the base and connecting the first and second boards for preventing the first and second boards from bending relative to the base. The first and second pivot holes are respectively formed on the sides of the first and second boards adjacent to the strengthening rib. The tube pivots relative to the main body.
