The existing wind shield generally utilizes gravity, and the wind direction is positive, so that the wind shield is opened by overcoming the gravity; when the wind direction is negative or no wind, the wind shield is naturally closed under the action of gravity. The embodiment provides a non-gravity-controlled wind deflector device for solving the technical problem that the gravity of a wind deflector needs to be overcome when the wind deflector is opened by utilizing the wind direction in the prior art.

The principle and implementation of a non-gravity controlled wind deflector device of the present embodiment will be described in detail below, so that those skilled in the art can understand the non-gravity controlled wind deflector device of the present embodiment without creative efforts.

As shown in fig. 1, the present embodiment provides a non-gravity controlled wind deflector device 100, the non-gravity controlled wind deflector device 100 comprising: a frame 110, a plurality of wind deflectors 120, and a plurality of stop members 130.

The non-gravity-controlled wind deflector device 100 of the present embodiment will be described in detail below.

In this embodiment, the frame 110 is a rectangular frame, at least one isolation plate 111 is disposed inside the frame 110, the frame 110 is divided into at least two accommodating spaces for accommodating the wind deflectors 120, each accommodating space corresponds to one fan 200, and each accommodating space is provided with a plurality of wind deflectors 120.

When the wind blocking plates 120 are in a state of blocking wind from passing through, the wind blocking plates 120 sequentially contact to close the accommodating cavity, and when the wind blocking plates 120 are in a state of allowing wind to pass through, the wind blocking plates 120 are parallel to open the accommodating cavity, so that the accommodating cavity forms a plurality of air channels 140, and the wind smoothly flows through.

In the present embodiment, as shown in fig. 1 and fig. 2, each wind deflector 120 is installed in the frame 110 through a rotating shaft 121, and can rotate in a horizontal direction relative to the frame 110. The wind direction itself is used to control the opening and closing of the wind deflector 120, and gravity is not used, so that energy is not consumed by overcoming the gravity of the wind deflector 120 when the wind deflector 120 rotates under the wind.

As shown in fig. 2, the wind deflector 120 includes a first wind deflector 122 connected to the rotating shaft 121, and a second wind deflector 123 connected to the first wind deflector 122 and forming a predetermined angle with the first wind deflector 122.

In the present embodiment, the preset angle between the second wind deflector 123 and the first wind deflector 122 is, but not limited to, 170 ° to 179 °.

In this embodiment, the second wind deflector 123 and the first wind deflector 122 form a predetermined angle therebetween, so that the wind deflector 120 forms a curved structure, and the wind deflector 120 can always rotate by wind when being blown by wind in a curved direction. If the first wind deflector 122 close to the rotating shaft 121 is parallel to the wind direction, the first wind deflector 122 cannot generate force to push the wind deflectors 120 to rotate, and at this time, the second wind deflector 123 far from the rotating shaft 121 forms a certain angle with the wind to generate force to push the wind deflectors 120 to rotate. If the first wind shielding plate 122 close to the rotation shaft 121 is not parallel to the wind direction, the wind blows the first wind shielding plate 122 to generate a force to push the wind shielding plate 120 to rotate.

In this embodiment, the first wind deflector 122 and the second wind deflector 123 are integrally formed.

In another embodiment, the first wind deflector 122 and the second wind deflector 123 may be connected by welding, bonding, riveting, or the like.

In this embodiment, one of the stop members 130 is disposed corresponding to one of the wind deflectors 120, and restricts the rotational position of the wind deflector 120 when the wind blows the wind deflector 120 to rotate. I.e. the wind deflector 120 is restricted from rotation between said stop feature 130 and the adjacent other wind deflector 120.

In the present embodiment, the stop member 130 is disposed on the upper frame or the lower frame of the frame 110, that is, in the present embodiment, one stop member 130 is correspondingly disposed on the upper end or the lower end of one wind deflector 120.

In another embodiment, the stop members 130 may also be disposed on the upper rim or the lower rim of the frame 110, that is, one stop member 130 is disposed at each of the upper and lower ends of one wind deflector 120.

Preferably, in this embodiment, the position of the stop member 130 is a position that blocks the wind deflector 120 from further rotating when the first wind deflector 122 rotates to be perpendicular to the upper and lower frames of the frame 110.

As shown in fig. 2 and 3, when the wind direction is as shown in fig. 2, the wind deflector 120 rotates and hits the stop member 130, and the wind deflector 120 does not rotate and is parallel to the wind direction. The air duct 140 is opened and the wind passes.

As shown in fig. 4 and 5, when the wind direction is as shown in fig. 4, the wind deflector 120 is restricted from rotating between the stop member 130 and the adjacent other wind deflector 120. Wind blows towards wind deflector 120, wind deflector 120 rotates, hits the wind deflector 120 that is close to, and wind deflector 120 no longer rotates, and perpendicular to the wind direction, wind channel 140 close, and wind is prevented from passing through.

Specifically, in the present embodiment, the stop component 130 is, but not limited to, a column-shaped protrusion fixed on the frame 110.

The operating principle of the non-gravity controlled wind deflector device 100 in this embodiment is as follows:

as shown in fig. 6 and 7, the non-gravity-controlled wind deflector device 100 in the present embodiment is placed at the outlet or inlet of the fan 200 in close contact with the fan 200.

Fig. 6 shows a schematic assembly of the non-gravity-controlled wind guard device 100 and the fan 200 in this embodiment when the wind blows out of the housing to dissipate heat. At this time, the wind direction is positive, and as shown in fig. 2 and 3, when the wind deflector 120 is blown, the wind deflector 120 rotates and hits the stopper member 130, the wind deflector 120 does not rotate any more, the wind deflector 120 rotates to the wind direction parallel to the wind direction, the wind tunnel 140 opens, and the wind blows out smoothly.

When the wind direction is negative, as shown in fig. 4 and 5, the wind deflector 120 is rotated to a direction approximately perpendicular to the wind direction by blowing the reverse wind deflector 120, and the wind deflectors 120 are kept in contact with each other and prevented from further rotating, so that the wind deflector is kept at an angle approximately perpendicular to the wind direction, the wind tunnel 140 is closed, and the wind is prevented from blowing in.

Fig. 7 shows a schematic assembly of the non-gravity-controlled wind guard device 100 and the fan 200 in this embodiment when wind blows into the chassis to dissipate heat. That is, the non-gravity controlled wind deflector device 100 of this embodiment may be used in an inverted position when assembled with respect to fig. 6.

Thus, when one fan 200 in the fan 200 set is damaged, the wind shielding plate 120 is closed by the reverse wind force to prevent the wind from reversely entering or exiting the fan 200 when the wind intends to reversely enter or exit the chassis from the fan 200.

As shown in fig. 6 and 7, an embodiment of the present invention further provides a fan 200, where the fan 200 includes the non-gravity controlled wind deflector device 100 as described above. The non-gravity controlled windscreen apparatus 100 has been described in detail above and will not be described further herein.
