However, the body 100 generates heat during operation, and the cooling effect of natural wind on the body 100 is reduced due to the shielding of the beautifying cover, thereby resulting in poor heat dissipation effect of the body 100.

Based on this, as shown in fig. 6, the antenna 10 provided by the present utility model further includes a cover 600, a rotating member 700, a connecting member 800, and a plurality of blades 900.

Since the plurality of blades 900 are connected to the outside of the cover 600, wind may exert a force on the plurality of blades 900 under the action of natural wind, thereby driving the cover 600 to rotate. In addition, since the cover 600 is formed with the plurality of ventilation holes 610, natural wind can enter or exit the accommodating space 620 through the ventilation holes 610 in the process of rotating the cover 600, that is, natural wind is promoted to exchange with the air in the accommodating space 620 through the ventilation holes 610, so that heat generated by the body 100 can be better carried away to the air outside the accommodating space 620, and the heat dissipation effect of the body 100 is improved.

It can be appreciated that the blade 900 may be a straight panel, or the blade 900 may be a curved panel, and the curved surface may better drive the cover 600 to rotate under the wind.

Wherein, the plurality of blades 900 may be uniformly disposed around the supporting bar 200 for one week. When the blades 900 drive the cover 600 to rotate, a uniform force can be applied to the periphery of the cover 600, so that the cover 600 can rotate stably and uniformly.

The second fixing ring 640 is sleeved on the supporting rod 200, and along the extending direction of the supporting rod 200, the first fixing ring 630 and the second fixing member are sequentially arranged at intervals, and the connecting member 800 is arranged between the second fixing ring 640 and the second rotating member 700, is connected with the second rotating member 700, and is connected with the second fixing ring 640.

The plurality of partition plates 650 are disposed between the first and second fixing rings 630 and 640 and are spaced around the supporting rod 200 at intervals to form the receiving space 620, one end of the partition plates 650 is connected with the first fixing ring 630, the other end of the partition plates 650 is connected with the second fixing ring 640, and the vent holes 610 are formed between two adjacent partition plates 650.

Through the above arrangement, the cover 600 is formed by the first fixing ring 630, the second fixing ring 640 and the plurality of spacers 650, thereby realizing shielding of the body 100 to achieve beautification. And simultaneously, a vent hole 610 is formed between two adjacent separators 650 to dissipate heat of the body 100 using the vent hole 610. Since the ventilation hole 610 is formed by the adjacent two separators 650, the process of opening holes can be omitted, and secondary processing can be omitted. And because of the first fixing ring 630 and the second fixing ring 640, the whole cover 600 can rotate in a cylinder shape, so that the whole cover is more attractive in the rotating process.

It will be appreciated that the spacer 650 should be of a non-shielding material such that the positioning of the spacer 650 does not affect the transmission or reception of signals by the body 100. In addition, the first and second fixing rings 630 and 640 may be identical in size or may be different in size.

Wherein the plurality of spacers 650 may be uniformly disposed around the support bar 200 for one week. In this way, the size of each ventilation hole 610 may be kept consistent, so that the air volume of the air inlet and outlet in unit time of each ventilation hole 610 is similar, thereby realizing uniform heat dissipation around the body 100.

Alternatively, the plurality of spacers 650 may be unevenly disposed around the support pole 200.

In addition, the partition 650 may be a straight panel, or the partition 650 may be a curved panel, for example, the partition 650 may have a parabolic cross section perpendicular to the arrangement direction of the first fixing ring 630 and the second fixing ring 640, so that the wind entering the accommodating space 620 may have a spiral shape, and thus, the heat of the body 100 may be better dissipated.

For example, as shown in fig. 7, the blade 900 may be coupled to an outer wall surface of the first fixing ring 630. So can make the setting of blade 900 not influence ventilation hole 610, can avoid blade 900 to shelter from ventilation hole 610 to guarantee the normal air inlet air-out of ventilation hole 610, make better radiating effect to body 100.

Alternatively, the blade 900 may be coupled to the outer wall surface of the second holder 640. So can make the setting of blade 900 not influence ventilation hole 610, can avoid blade 900 to shelter from ventilation hole 610 to guarantee the normal air inlet air-out of ventilation hole 610, make better radiating effect to body 100.

By the rotation of the drum, heat dissipation to the body 100 is realized on the basis of beautification.

On this basis, as shown in fig. 8, the connection member 800 may include a plurality of connection bars 810, one end of the connection bar 810 is connected to the rotation member 700, the other end of the connection bar 810 is connected to the cover 600, and the plurality of connection bars 810 are disposed around the support bar 200 (not shown in fig. 8) at intervals.

In this way, the plurality of connection rods 810 can stably connect the cover 600 to the rotation member 700 in the circumferential direction of the support bar 200, thereby enabling the cover 600 to rotate more stably.

And in the case where the cover 600 includes the first fixing ring 630, the second fixing ring 640, and the partition 650, wind may also enter or exit the receiving space 620 through the gap between the connection rods 810. This can better dissipate heat from the body 100.

Alternatively, the connection member 800 may include a connection plate disposed around the support bar 200 in a circle, thereby stably connecting the cover 600 to the rotation member 700. Of course, the connector 800 may be any other suitable shape.

In some embodiments, in order to achieve the rotational coupling of the rotational member 700 with the support bar 200, as shown in fig. 9, a groove 230 is formed on the support bar 200, and the groove 230 is formed around the support bar 200 for one revolution. As shown in fig. 10, a rotation hole 710 is formed in the rotation member 700, the rotation member 700 is sleeved on the support rod 200 through the rotation hole 710, and the edge of the rotation hole 710 extends into the groove 230.

In this way, when the blades 900 are pushed by wind, the blades 900 apply a torsion force to the cover 600, and act on the connecting piece 800 and then act on the rotating piece 700, and the rotating piece 700 rotates around the supporting rod 200 under the action of the torsion force because the edge of the rotating hole 710 extends into the groove 230. Thereby achieving a rotational connection of the rotational member 700 with the supporting bar 200.
