[0024] Reference Figures 1 to 6 This utility model embodiment provides an invisible fan, which includes a body 100, a rotating disk 200, a connector 310, fan blades 400, and a linkage rod 500.
[0025] A rotating disk 200 is rotatably mounted on the upper side of the body 100. Three connecting members 310 are rotatably mounted on the rotating disk 200, evenly distributed around its circumference. Each connecting member 310 is fitted with an elastic element 320, which is a torsion spring. The two ends of the elastic element 320 are connected to the connecting member 310 and the rotating disk 200, respectively. Three fan blades 400 are provided, each with a connecting end 410. The three connecting ends 410 are synchronously and rotatably connected to the three connecting members 310. 400 is located on the upper side of the rotating disk 200. There are three linkage rods 500. The two ends of the linkage rods 500 are rotatably connected to two adjacent connecting parts 310 along the circumference of the rotating disk 200. The linkage rods 500 are located between the rotating disk 200 and the machine body 100. The machine body 100 can drive the rotating disk 200 to rotate, so as to drive the three fan blades 400 to rotate and unfold synchronously through the linkage rods 500. When the rotating disk 200 stops rotating, the elastic element 320 can drive the three fan blades 400 to rotate and retract synchronously under the action of the linkage rods 500.
[0026] It is understandable that the rotating disk 200 is connected to the motor on the machine body 100, and the motor can drive the rotating disk 200 to rotate.
[0027] It is understandable that the process by which the rotating disk 200 drives the three fan blades 400 to rotate and unfold synchronously via the linkage rod 500 is as follows: the rotating disk 200 rotates, the fan blades 400 rotate under the action of centrifugal force and wind resistance, the elastic element 320 deforms and stores force, at this time, the rotating fan blades 400 drive the connecting piece 310 to rotate, so that the linkage rod 500 connected to the connecting piece 310 pulls the adjacent connecting piece 310 to rotate, thereby driving the adjacent fan blades 400 to rotate, thus enabling the three fan blades 400 to rotate and unfold synchronously.
[0028] It is understandable that when the rotating disk 200 stops rotating, the elastic element 320 can drive the three fan blades 400 to rotate and retract synchronously under the action of the linkage rod 500 as follows: the rotating disk 200 stops rotating, the elastic element 320 resumes to drive the connecting piece 310 to rotate, which in turn drives the fan blades 400 connected to the connecting piece 310 to rotate and retract. At this time, the rotating connecting piece 310 pushes the adjacent connecting piece 310 to rotate through the linkage rod 500 connected to it, thereby driving the adjacent fan blades 400 to rotate, so that the three fan blades 400 can rotate and retract synchronously.
[0029] With the above structure, on the one hand, by hiding the linkage rod 500 between the rotating disk 200 and the body 100, the damage to the overall visual effect caused by the exposed linkage rod 500 can be effectively reduced, and the appearance of the fan blades 400 when the fan is stopped and retracted can be optimized; on the other hand, the hidden setting of the linkage rod 500 can effectively reduce the interference of external objects or human contact on the transmission process, thereby ensuring the stability and reliability of the linkage unfolding and retracting action of the fan blades 400.
[0030] In some embodiments, refer to Figure 7 There are four connectors 310, fan blades 400, and linkage rods 500.
[0031] Connector 310 is rotatably mounted on rotating disk 200. Three connecting ends 410 are synchronously rotatably connected to the three connectors 310. Elastic members 320 are sleeved on the connectors 310. The two ends of the linkage rod 500 are rotatably connected to two adjacent connectors 310 along the circumference of rotating disk 200. For details, refer to... Figures 3 to 5 The connector 310 is provided with a rod portion 311 and a plate portion 312. The rod portion 311 is rotatably inserted through the rotating disk 200. An elastic element 320 is sleeved on the rod portion 311. The three rod portions 311 are synchronously rotatably connected to the three connecting ends 410 in a one-to-one correspondence. The plate portion 312 is located on the lower side of the rotating disk 200. The two ends of the linkage rod 500 are rotatably connected to the plate portions 312 of the corresponding two connectors 310 in a one-to-one correspondence.
[0032] It is understandable that the two ends of the linkage rod 500 are rotatably connected to the plate portions 312 of the two corresponding connectors 310 in a one-to-one correspondence, that is, the two ends of the linkage rod 500 are rotatably connected to the plate portions 312 of the two adjacent connectors 310 along the circumference of the rotating disk 200 in a one-to-one correspondence.
[0033] One end of the elastic element 320 is connected to the connector 310. For details, refer to... Figures 3 to 5 The rod 311 is fitted with a disc 600 that can rotate synchronously with it, and one end of the elastic member 320 is connected to the disc 600 to indirectly connect with the connector 310.
[0034] The rod 311 is fitted with a disc 600 that can rotate synchronously with it; for details, refer to... Figure 5 The rod 311 has a rod segment with a hexagonal cross-section (not shown in the figure), and the disc 600 has a through hole with a hexagonal cross-section (not shown in the figure). The disc 600 is sleeved on the rod segment through the through hole.
[0035] The rod 311 and the corresponding connecting end 410 are rotatably connected, as detailed in the following document. Figures 3 to 6The top of the rod 311 has a hexagonal cross-section insertion part (not shown in the figure), and the connecting end 410 has a hexagonal cross-section insertion hole (not shown in the figure). The insertion part is inserted into the corresponding insertion hole of the connecting end 410. A bolt (not shown in the figure) passes through the rod 311, and a nut (not shown in the figure) is threaded onto the bolt. The head of the bolt and the nut together clamp the rod 311 and the connecting end 410. Under the clamping action, the connecting end 410 abuts against the upper side of the rotating disk 200, and the disk 600 abuts against the lower side of the rotating disk 200 and the abutment platform 311A at the lower end of the rod 311.
[0036] In this embodiment, refer to Figure 3 The disc 600 is rotatably mounted on the rotating disk 200, and the top side of the disc 600 is provided with a plurality of sliding balls, and the top side of the disc 600 abuts against the bottom side of the rotating disk 200 through the sliding balls.
[0037] With the above structure, the top side of the disc 600 abuts against the bottom side of the rotating disk 200 via ball bearings, which reduces the frictional resistance between the disc 600 and the rotating disk 200 when the fan blade 400 and the connecting member 310 rotate synchronously relative to the rotating disk 200. Furthermore, the disc 600 can distribute the force it receives to a larger area on the bottom side of the rotating disk 200 via multiple ball bearings, thus avoiding stress concentration.
[0038] To improve the structural compactness, refer to Figure 3 The disc 600 and the elastic element 320 are sequentially sleeved on the rod 311. The disc 600 is provided with a receiving groove 610, and the elastic element 320 is provided in the receiving groove 610.
[0039] The end of the linkage 500 is rotatably connected to the corresponding plate 312. For details, refer to... Figures 3 to 5 The top side of the plate 312 is provided with a protrusion 312A, and the end of the linkage rod 500 is provided with a collar 510, which is rotatably sleeved on the corresponding protrusion 312A.
[0040] In this embodiment, refer to Figures 3 to 5 The disc 600 is provided with an extension block 620, which is located on the upper side of the corresponding collar 510 to restrict it from disengaging from the corresponding protrusion 312A, thereby ensuring the rotational connection between the end of the linkage rod 500 and the corresponding plate 312.
[0041] Furthermore, refer to Figures 3 to 5 The extension block 620 is provided with a groove 621, and the protrusion 312A is inserted into the corresponding groove 621.
[0042] With the above structure, the protrusion 312A is inserted into the corresponding groove 621, which can play a positioning role to ensure that the extension block 620 is always located on the upper side of the corresponding collar 510 so as to prevent it from coming out of the corresponding protrusion 312A.
[0043] In this embodiment, refer to Figure 4 and Figure 6 The connecting end 410 is provided with a limiting groove 411, and the rotating disk 200 is provided with a limiting block 210. The limiting block 210 is slidably disposed in the corresponding limiting groove 411. The limiting block 210 and the corresponding limiting groove 411 can limit the rotatable angle of the corresponding fan blade 400.
[0044] In some embodiments, a limiting groove 411 is provided on the rotating disk 200, and a limiting block 210 is provided on the connecting end 410.
[0045] In this embodiment, refer to Figure 2 and Figure 3 The rotating disk 200 has a downward-facing annular edge 220 on its periphery, and the linkage rod 500 is located inside the edge 220.
[0046] With the above structure, the downward-facing annular edge 220 can shield the linkage rod 500 on its inner side, thereby further improving the concealment of the linkage rod 500, optimizing the aesthetic appearance of the product, and reducing external interference to the linkage rod 500.
[0047] This utility model also proposes a concealed fan light, see reference. Figure 1 This includes the aforementioned concealed fan. Through this structure, the linkage 500 can be concealed, optimizing the product's aesthetic appearance and reducing external interference to ensure operational stability.
[0048] In this embodiment, refer to Figure 8 The bottom of the body 100 is provided with a mounting cavity 110, which has a downward-facing opening. The mounting cavity 110 is provided with an electrically connected lamp source 710 and a power drive 720. The bottom of the body 100 is detachably connected to a light-transmitting cover 800 by a rotating snap-fit mechanism, which covers the opening.
[0049] With the above structure, the user can remove the face cover 800 to open the opening, so that the user can perform inspection, maintenance, replacement, installation and other work on the lamp source component 710 and the power drive component 720.
[0050] Of course, this utility model is not limited to the above-described embodiments.
