It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Figure 1 A schematic diagram of an air induction device used in an air duct provided in this embodiment.

[0028] like Figure 1 As shown, the air induced draft device for the air duct of this embodiment includes a partition 1, an induced draft fan 2 and at least one air duct 3. The partition 1 is arranged in the air duct 6. The partition 1 divides the air duct 6 into a front part 61 and a rear part 62. The partition 1 includes at least one through hole. The induced draft fan 2 is arranged in the rear part 62 of the air duct 6 and is close to the partition 1. The induced draft fan 2 is used to guide the air-conditioned air in the air duct 6 to the partition 1. The air duct 3 is arranged in the front part 61 of the air duct 6. The two ends of the air duct 3 are an air inlet end and an air outlet end, respectively. The air inlet end is connected to the through hole. The air outlet end extends to the driver area through the air duct 6.

[0029] The specifications and gears of the induced draft fan 2 of this embodiment can be selected according to actual needs, and the installation positions of the partition 1 and the induced draft fan 2 and the length of the air duct 3 are also determined according to the actual size of the vehicle's air duct 6. This embodiment does not impose too many restrictions on this.

[0030] The air induction device for the air duct of this embodiment includes a partition 1, an induced draft fan 2 and at least one air duct 3. The partition 1 is arranged in the air duct 6 and divides the air duct 6 into a front part 61 and a rear part 62, and the front part 61 is located above the driver area. The partition 1 includes at least one through hole. The induced draft fan 2 is arranged in the rear part 62 of the air duct 6 and is close to the partition 1. The induced draft fan 2 can guide the air conditioning air in the air duct 6 to the partition 1. The air duct 3 is arranged in the front part 61 of the air duct 6, and the air inlet end of each air duct 3 is connected to a through hole on the partition 1, and the air outlet end of the air duct 3 extends to the driver area through the air duct 6. When the cold air volume or hot air volume in the driver's area is insufficient, the induced draft fan 2 is turned on, and the air-conditioned air in the air duct 6 can flow to the partition 1 under the action of the induced draft fan 2, and enter the air duct 3 through the through hole on the partition 1, and is transported to the driver's area by the air duct 3, which makes up for the problem of insufficient air-conditioned air volume in the driver's area, which is conducive to improving the comfort of the driver's area, putting the driver in a good working environment, preventing high temperature or cold weather from affecting the driver's physical condition, and improving driving safety. In addition, this solution uses at least one air duct 3 to transport air-conditioned air to the driver's area, reducing the cross-sectional area of ​​the air-conditioned air channel, increasing the pressure of the air-conditioned air, and is conducive to increasing the wind speed. In addition, the air duct 6 is divided into a front part 61 and a rear part 62 by the partition 1, which is equivalent to shortening the air duct in the passenger area, and plays a role in pressurizing the area of ​​the rear part 62 of the air duct 6, which is conducive to increasing the air-conditioned wind speed in the passenger area.

[0031] It should be noted that the air induction device for the air duct provided in this embodiment can be applied not only to new cars but also to old car modification, and has a wide range of applications. Moreover, the air induction device for the air duct provided in this embodiment can be used not only to deliver conditioned air to the driver area but also to deliver conditioned air to other areas of the vehicle where the air volume is insufficient, such as the rear of the vehicle.

[0032] In some embodiments, Figure 1 As shown, the distance between the partition 1 and the induced draft fan 2 is L, 200mm≤L≤400mm. The distance between the partition 1 and the induced draft fan 2 of this embodiment is 200mm≤L≤400mm, which can not only reserve enough space for the air conditioning wind in the air duct 6 to flow to the partition 1, but also prevent the induced draft fan 2 from causing too much impact on the air outlet of the rear part 62 of the air duct 6. However, it can be understood that in other embodiments, the distance between the partition 1 and the induced draft fan 2 can also be outside the numerical range of this embodiment, and can be specifically set according to the size of the air duct 6 and the position of the air conditioner, and this embodiment does not impose too many restrictions on this.

[0033] In some embodiments, Figure 1 As shown, the air duct 6 also includes a fixing bracket 4. The induced draft fan 2 is fixed in the air duct 6 through the fixing bracket 4. The induced draft fan 2 of this embodiment is fixed in the air duct 6 through the fixing bracket 4, which can not only ensure the firmness of the connection between the induced draft fan 2 and the air duct 6, but also reduce the difficulty of installing the induced draft fan 2. In addition, installing the induced draft fan 2 in the air duct 6 through the fixing bracket 4 can make the induced draft fan 2 closer to the middle position of the air duct 6, so that there is a gap between the induced draft fan 2 and the inner wall of the air duct 6, which is conducive to the smooth circulation of air conditioning air.

[0034] In some embodiments, Figure 1 As shown, the fixing bracket 4 includes a transverse portion 41 and a vertical portion 42 connected to each other. The transverse portion 41 is connected to the top of the air duct 6. The induced draft fan 2 is installed on the vertical portion 42. The fixing bracket 4 of this embodiment has a transverse portion 41 and a vertical portion 42. The transverse portion 41 can fit with the inner wall of the top of the air duct 6, which is convenient for the connection and fixation between the fixing bracket 4 and the air duct 6, and is convenient for the installation and removal of the fixing bracket 4 in the air duct 6. The vertical portion 42 forms an angle with the inner wall of the top of the air duct 6, which is convenient for the installation of the induced draft fan 2 and avoids interference between the induced draft fan 2 and the structure at the top of the air duct 6.

[0035] It should be noted that, in this embodiment, the connection between the transverse portion 41 of the fixing bracket 4 and the inner wall of the air duct 6 can be welding or bolting, and this embodiment does not impose too many restrictions on this.

[0036] In some embodiments, Figure 1As shown, the air duct 3 is L-shaped, including a first pipe section 31 and a second pipe section 32 connected to each other. The free end of the first pipe section 31 is the air inlet end. The extension direction of the first pipe section 31 is parallel to the extension direction of the air duct 6. The free end of the second pipe section 32 is the air outlet end. The extension direction of the second pipe section 32 forms an angle with the extension direction of the air duct 6. And the free end of the second pipe section 32 is connected to the outside of the air duct 6. The air duct 3 of this embodiment is set to be L-shaped, wherein the first pipe section 31 connected to the through hole is parallel to the extension direction of the air duct 6, that is, the first pipe 31 is the same as the induced air flow direction of the induced draft fan 2, so the flow velocity loss of the wind in the first pipe section 31 can be reduced. The extension direction of the second pipe section 32 forms an angle with the extension direction of the air duct 6, that is, it can guide the air conditioning wind in the air duct 3 to change direction and flow to the driver area, further increasing the air volume in the driver area. Furthermore, in order to prevent the connection between the first pipe section 31 and the second pipe section 32 from obstructing the air conditioning wind, the connection between the first pipe section 31 and the second pipe section 32 is designed to be a smooth transition, so that the air conditioning wind in the air duct 3 can be smoothly turned, thereby reducing wind speed loss.

[0037] In some embodiments, Figure 1 As shown, the front portion 61 of the air duct 6 is provided with an air outlet 5. The free end of the second pipe section 32 is connected to the air outlet 5. In this embodiment, the front portion 61 of the air duct 6 is provided with an air outlet 5, the air outlet 5 corresponds to the driver area, and the second pipe section 32 is connected to the air outlet 5. The driver can adjust the angle and outlet size of the air outlet 5 according to his own needs, thereby controlling the air volume and wind direction of the air outlet, which is more flexible and convenient to use.

[0038] In some embodiments, Figure 1 As shown, the partition 1 includes a plurality of through holes. The plurality of through holes are arranged in sequence along the vertical direction. Each air duct 3 is connected to a through hole, and the air ducts 3 are parallel to each other. The partition 1 of this embodiment is provided with a plurality of through holes and arranged in sequence along the vertical direction, which can make the layout of the air duct 3 in the air duct 6 more compact and reasonable, and the plurality of through holes and air ducts 3 are provided, which can ensure that the driver area obtains sufficient air volume.
