Please referring to FIG. 1, FIG. 2 and FIG. 3, which are respectively a stereoscopic assembling diagram, a stereoscopic exploded view and a section view of a hidden fan according to a first example of the present disclosure. As shown in the drawings, the present example provides a hidden fan 1 which includes a turntable assembly 10 and a plurality of fan blade assemblies 11. The plurality of fan blade assemblies 11 are respectively pivoted to the turntable assembly 10. When the turntable assembly 10 rotates, the fan blade assemblies 11 are driven to unfold. The turntable assembly 10 has a turntable 101 and a limit wheel 102. The limit wheel 102 is pivoted to the turntable 101 and rotates relative to the turntable 101. The turntable 101 has a drive portion 1011 and a plurality of fan blade fixing portions 1012. The drive portion 1011 is located at the center of the turntable 101 and used to connect a drive source. The drive source is connected with the drive portion 1011 so as to drive the turntable 101 to rotate. The drive portion 1011 of the present example is a connection bump 1013 protruding from the center of the turntable 101. The connection bump 1013 has a mounting penetrating groove 1014. The plurality of fan blade fixing portions 1012 are annularly arranged around the center of the drive portion 1011 of the turntable 101. The plurality of fan blade fixing portions 1012 are equally spaced apart from each other.

The limit wheel 102 is sleeved on the connection bump 1013 of the drive portion 1011 and can rotate relative to the drive portion 1011. The limit wheel 102 has a plurality of limit grooves 1021. The plurality of limit grooves 1021 are annularly arranged around the center of the drive portion 1011 of the turntable 101 and surround a peripheral edge of the drive portion 1011. Each limit groove 1021 is a linear groove. An extension direction of each limit groove passes through the center of the drive portion 1011 of the turntable 101. The plurality of limit grooves 1021 are equally spaced apart from each other. The plurality of limit grooves 1021 respectively correspond to the plurality of fan blade fixing portions 1012. The number of the fan blade fixing portions 1012 is the same as that of the limit grooves 1021. In the present example, each fan blade fixing portion 1012 is located at a side of the corresponding limit groove 1021. The fan blade fixing portions 1012 of the present example are fixing grooves 1015, a fixing hole 1016 is at the center of the fixing groove 1015, and a bottom edge of the fixing groove has an arc fixing groove 1017.

A side surface of the connection bump 1013 of the drive portion 1011 has a plurality of positioning blocks 1018 that are equally spaced apart from each other. A space is between each positioning block 1018 and the surface, with the drive portion 1011, of the turntable 101. The space is greater than or equal to a thickness of the limit flange 1023. When the limit wheel 102 is sleeved on the drive portion 1011, the mounting opening 1022 of the limit wheel 102 is sleeved on the connection bump 1013 of the drive portion 1011, and in this case, the plurality of notches 1024 of the limit flange 1023 of the limit wheel 102 correspond to the plurality of positioning blocks 1018 of the connection bump 1013, so that the limit flange 1023 of the limit wheel 102 can successfully penetrate through an end, with the plurality of positioning blocks 1018, of the connection bump 1013. After the limit flange 1023 of the limit wheel 102 enters the space between the positioning blocks 1018 and the surface, with the drive portion 1011, of the turntable 101, the limit wheel 102 rotates by an angle to enable the limit flange 1023 to correspond to the positioning blocks 1018, so as to prevent the limit wheel 102 from separating from the drive portion 1011.

A material of the turntable assembly 10 of the present example is plastic cement. The number of the parts of the turntable assembly of the present example is reduced to two, so that not only is the number of the parts of the turntable assembly 10 of the existing hidden fan reduced, and is the convenience in assembling increased, but also the rotating resistance of the turntable assembly 10 of the present example during the operation is smaller than the rotating resistance of the turntable assembly of the existing hidden fan and relatively decreases by 30%.

The plurality of fan blade assemblies 11 are respectively arranged at the fan blade fixing portions 1012. Each fan blade assembly 11 includes a fan blade 111, a return elastic component 112 and a fixed component 113. The return elastic component 112 may be, for example, a spring or another type of flexible elastic object. An end of the fan blade 111 has a fixed portion 1111 and a linkage portion 1112 connected to a side of the fixed portion 1111. In the case that the fan blade 111 is arranged at the corresponding fan blade fixing portion 1012, the fixed portion 1111 of the fan blade 111 is arranged in the fixing groove 1015 of the corresponding fan blade fixing portion 1012, and the return elastic component 112 is arranged between the fixed portion 1111 and the fixing groove 1015, an end of the return elastic component 112 is fixed at the fixed portion 1111, and the other end is fixed in the arc fixing groove 1017.

The fixed component 113 penetrates through the fixed portion 1111 and is fixed in the fixing hole 1016 of the turntable 101 so as to fix the fan blade assembly 11 on the fan blade fixing portion 1012. The linkage portion 1112 of the fan blade 111 is connected with the corresponding limit groove 1021.

The fixed portion 1111 of the ban blade 111 has a groove 1113, a first hollow fixed column 1114 and a second hollow fixed column 1115. The groove 1113 is arranged on an outer surface of the fan blade 111, and the bottom of the groove 1113 has a through hole 1116. The first hollow fixed column 1114 is arranged on an inner surface of the fan blade 111 and corresponds to the groove 1113. The second hollow fixed column 1115 is arranged on the inner surface of the fan blade 111 and located in the first hollow fixed column 1114. A central axe of the first hollow fixed column 1114 and a central axe of the second hollow fixed column 1115 penetrate through the center of the through hole 1116. An outer diameter of a cross section of the first hollow fixed column 1114 is smaller than a diameter of the fixing groove 1015, and an inner diameter of the cross section of the first hollow fixed column 1114 is greater than an outer diameter of the return elastic component 112. An outer diameter of the cross section of the second hollow fixed column 1115 is smaller than the inner diameter of the return elastic component 112. In the case that the fixed portion 1111 is arranged in the fixing groove 1015, the return elastic component 112 is located between the first hollow fixed column 1114 and the second hollow fixed column 1115, and an end of the return elastic component 112 is fixed at the second hollow fixed column 1115. The fixed component 113 passes through the through hole 1116 of the groove 1113 and the second hollow fixed column 1115 so as to fix the fan blade 111 on the turntable 101. An inner side wall of the second hollow fixed column 1115 of the present example is additionally provided with a bearing 1117. The bearing 1117 is integral with the fan blade 111 by insert molding. The inner surface of the bearing 1117 has a tooth portion to improve the connection property with the second hollow fixed column 1115 of the fan blade 111. When the fixed component 113 fixes the fixed portion 1111 of the fan blade 111 onto the turntable 101, the fixed component 113 passes through the through hole 1116 of the groove 1113 and the bearing 1117. The bearing 1117 can reduce the friction between the fixed component 113 and the fixed portion 1111 of the fan blade 111 when the fan blade 111 rotates, so that the fan blade 111 can rotate smoothly.

In the present example, the linkage portion 1112 has a linkage column 1118. The linkage column 1118 is arranged in the limit groove 1021, so that the linkage portion 1112 is connected with the corresponding limit groove 1021. In the present example, an end, which is arranged in the limit groove 1021, of the linkage column 1118 has a positioning convex portion 1119. A diameter of the positioning convex part 1119 is greater than a width of the limit groove 1021. When the linkage column 1118 is arranged in the limit groove 1021, the positioning convex portion 1119 passes through the limit groove 1021 and abuts the bottom surface of the limit groove 1021 so as to prevent the linkage column 1118 from separating from the limit groove 1021. When the linkage column 1118 in the present example works, the linkage column 1118 is located at an end, away from the drive portion 1011, of the limit groove 1021, an end, close to the drive portion 1011, of the limit groove 1021 in the present example has a mounting hole 1025, and an aperture of the mounting hole 1025 is greater than or equal to the diameter of the positioning convex portion 1119. When the linkage column 1118 is to be arranged in the limit groove 1021, the positioning convex portion 1119 enters from the mounting hole 1022, the linkage column 1118 moves from an end, close to the drive portion 1011, of the limit groove 1021 to an end, away from the drive portion 1011, of the limit groove 1021 along the limit groove 1021 so as to complete the assembling of the linkage column 1118.

The surface of the fan blade 111 in the present example is an arc surface. A surface of an end, with the fixed portion 1111, of the fan blade 111 is lower than a surface of an end, opposite to the fixed portion 1111, of the fan blade 111. The surface of an end may be, for example, a top surface or bottom surface of the blade. When the hidden fan 1 folds, the surface of the end, opposite to the fixed portion 1111, of the fan blade 111 is superimposed on the end of the surface, with the fixed portion 1111, of the adjacent fan blade 111. When the hidden fan 1 folds, the limit groove 1021 is located at a right side of the fixed portion 1111 of the fan blade 111. When the hidden fan 1 in the present example works, the drive portion 1011 of the turntable 101 is driven by the drive source, and the drive portion 1011 drives the turntable 101 to rotate clockwise.

The number of the parts of the fan blade assembly 11 in the present example is less than that of the parts of the fan blade assembly of the existing hidden fan, so that the assembling is easy, and the assembling precision is greatly improved.

As shown in the drawing, along with the clockwise rotation of the turntable 101, the folded fan blades 111 unfold outwards under the action of a centrifuging force, in this case, the linkage portions 1112 of the fan blades 111 are respectively connected with the corresponding limit grooves 1021 to drive the limit wheel 102 to rotate clockwise. The linkage portions 1112 of the fan blades 111 drive the corresponding limit grooves 1021 to move to a left side of the fixed portion 1111 of the fan blade 111. When the fan blades 111 unfold outwards, the fan blades 111 stretch the return elastic components 112. When the drive source stops driving the drive portion 1011 of the turntable 101, the stretched return elastic components 112 generate a return force to automatically pull the fan blades 111 to fold inwards. At the same time, the linkage portions 1112 of the fan blades 111 drive the limit grooves 1021 to rotate, and the linkage portions 1112 of the fan blades 111 drive the corresponding limit grooves 1021 to move to the right side of the fixed portion 1111 of the fan blade 111, i.e. a position before the rotation of the limit wheel 102.
