DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1 As shown, this figure is an exploded view of a fan device for seat ventilation provided in an embodiment of the present application, the device comprising: The shell structure is hollow inside to form an installation space, in which a fan body 1 is installed; the shell structure has a first air outlet 2, a second air outlet 3, a third air outlet 4 and a fourth air outlet 5 which are connected to the installation space.

[0030] It should be noted that if Figure 1 As shown, the shell structure includes: The upper shell 16, the middle shell 17 and the lower shell 18 are connected to each other, the space between the upper shell 16 and the middle shell 17, and the space between the middle shell 17 and the lower shell 18 together form an installation space; the first air outlet 2 is opened on the upper shell 16, and the fourth air outlet 5 is opened on the lower shell 18; an air guide port is formed between the upper shell 16 and the lower shell 18, and the middle shell 17 divides the air guide port into a second air outlet 3 and a third air outlet 4; here, the air guide port corresponds to the air outlet setting of the fan body 1.

[0031] The air inlet of the fan body 1 is connected to the first air outlet 2 and the second air outlet 3, and the air outlet of the fan body 1 is connected to the third air outlet 4 and the fourth air outlet 5. Here, the fan body 1 is installed between the lower shell 18 and the middle shell 17, and an opening is opened on the middle shell 17 so that the air inlet of the fan body 1 is connected to the first air outlet 2 and the second air outlet 3.

[0032] The ventilation assembly includes: a flip structure and a driving structure arranged in the installation space; the flip structure has a driven flap 6 and an active flap 7 rotatably arranged in the installation space, the driven flap 6 is arranged corresponding to the first air outlet 2 and the second air outlet 3, and the active flap 7 is arranged corresponding to the third air outlet 4 and the fourth air outlet 5; the driving end of the driving structure is transmission-connected to the active flap 7, and the driven flap 6 is transmission-connected to the active flap 7; The driving structure drives the active flap 7 and the driven flap 6 to rotate synchronously, thereby switching the connection between each air outlet and the installation space to form a blowing channel or a suction channel.

[0033] Among them, the driven flap 6 is used to separate the first air outlet 2 from the installation space or to separate the second air outlet 3 from the installation space; the active flap 7 is used to separate the third air outlet 4 from the installation space or to separate the fourth air outlet 5 from the installation space.

[0034] like Figure 2 and Figure 3 As shown, when the driving structure drives the active flap 7 to rotate, the driven flap 6 is pulled down to rotate the driven flap 6, thereby separating the second air port 3 and the fourth air port 5, and using the first air port 2, the installation space, the fan body 1 and the third air port 4 to conduct and form a blowing channel. The gas flow direction of this blowing channel is as shown in FIG. Figure 3 As shown by the dotted arrow in Figure 4 and Figure 5 As shown, when the driving structure drives the active flap 7 to rotate, the driven flap 6 is lifted, so that the driven flap 6 rotates, thereby separating the first air port 2 and the third air port 4, and using the second air port 3, the installation space, the fan body 1 and the fourth air port 5 to conduct and form an air suction channel. The gas flow direction of this air suction channel is as shown in FIG. Figure 5 As shown by the dotted arrow in .

[0035] The present application drives the active flap 7 and the driven flap 6 to rotate synchronously through a driving structure, switches different air outlets and installation spaces, and connects the fan body 1, thereby forming an air suction channel or an air blowing channel, which can reduce the risk of jamming and achieve rapid conversion.

[0036] Furthermore, the flip structure also includes: A connecting member 8 is slidably disposed in the installation space, and a sliding direction of the connecting member 8 is perpendicular to the surface of the shell structure; the driven flap 6 and the active flap 7 are rotatably connected through the connecting member 8; When the active flap 7 rotates, the connecting member 8 lifts or pulls down the driven flap 6, thereby driving the driven flap 6 to rotate.

[0037] The force of the active flap 7 is transmitted to the driven flap 6 through the connecting member 8, thereby driving the driven flap 6 to rotate.

[0038] Among them, a first connecting rod 9 and a second connecting rod 10 connected in rotation are arranged in the installation space, the first connecting rod 9 is connected to the driven flap 6, and the second connecting rod 10 is connected to the active flap 7. When the driving structure switches the state of the two flaps, the first connecting rod 9 and the second connecting rod 10 can rotate to drive the driven flap 6 and the active flap 7 to rotate.

[0039] Furthermore, if Figure 6 As shown, the connecting member 8 comprises: The connecting body is provided with a first guide groove 11 and a second guide groove 12; the first guide groove 11 is slidably connected to the first protrusion 20 of the driven flap 6, and the second guide groove 12 is slidably connected to the second protrusion 21 of the active flap 7. The first guide groove 11 and the second guide groove 12 respectively guide the rotation and movement of the first protrusion 20 of the driven flap 6 and the second protrusion 21 of the active flap 7. Here, the first guide groove 11 is in an arc shape, and the second guide groove 12 is in a strip shape, so that the driven flap 6 and the active flap 7 can rotate smoothly and stably.

[0040] In addition, if Figure 8 As shown, a slide groove 19 is provided between the lower shell 18 and the middle shell 17, the end of the slide groove 19 is connected to the part of the installation space located between the middle shell 17 and the upper shell 16, and the slide groove 19 is slidably connected to the connecting member 8. The slide groove 19 has a guiding effect on the connecting member 8, and when the driving structure drives the flip structure to rotate, the connecting body slides relative to the slide groove 19 at the same time.

[0041] Furthermore, if Figure 7 As shown, the drive structure includes: The driving motor 13 and the gear set used in conjunction with each other, The gear set includes a driving gear 14 and a driven gear 15 which are meshed with each other. The driving gear 14 is connected to the driving shaft of the driving motor 13 , and the driven gear 15 is connected to the first connecting rod 9 or the second connecting rod 10 .

[0042] The driving force of the driving motor 13 is transmitted to the active flap 7 through the active gear 14 and the driven gear 15, thereby driving the active flap 7 and the driven flap 6 to rotate, so that the device is in the blowing mode or the suction mode.

[0043] like Figure 2 As shown, when the device is in the blowing mode, the driven flap 6 separates the third air outlet 3 from the installation space, the active flap 7 separates the fourth air outlet 5 from the installation space, and the connecting member 8 is located in the slide slot 19, that is, relatively away from the side of the upper shell 16; when the device needs to be switched to the suction mode, as shown in FIG. Figure 4As shown, the driving structure can drive the active flap 7 to rotate, and the second protrusion 21 of the active flap 7 moves in the second guide groove 12, thereby pushing the connecting member 8 to move along the slide groove 19 to the side away from the lower shell 18, thereby driving the driven flap 6 to rotate. At this time, the first protrusion 20 of the driven flap 6 slides along the first guide groove 11, so that the driven flap 6 separates the first air outlet 3 from the installation space, and the active flap 7 separates the third air outlet 4 from the installation space.

[0044] Alternatively, the driving structure may also be transmission-connected to the driven flap 6. Specifically, the driving structure includes: The driving motor 13 and the gear set used in conjunction with each other, The gear set includes a driving gear 14 and a driven gear 15 which are meshed with each other. The driving gear 14 is connected to the driving shaft of the driving motor 13 , and the driven gear 15 is connected to the first connecting rod 9 .

[0045] Correspondingly, when the device is in the blowing mode, the driven flap 6 separates the third air outlet 3 from the installation space, the active flap 7 separates the fourth air outlet 5 from the installation space, and the connecting member 8 is located in the slide groove 19, that is, on the side relatively away from the upper shell 16; when the device needs to switch to the suction mode, the driving structure drives the first connecting rod 9 to rotate, and then drives the driven flap 6 to rotate, and the first protrusion 20 of the driven flap 6 moves in the first guide groove 11, and then pulls the connecting member 8 along the slide groove 19 to the side away from the lower shell 18, thereby driving the active flap 7 to rotate. At this time, the second protrusion 21 of the active flap 7 slides along the second guide groove 12, so that the driven flap 6 separates the first air outlet 3 from the installation space, and the active flap 7 separates the third air outlet 4 from the installation space.

[0046] The above-mentioned solution and implementation method of the present application are mainly explained by the transmission connection between the driving structure and the second connecting rod 10.

[0047] The present application also provides a vehicle seat ventilation system, comprising: the above-mentioned fan device for seat ventilation.
