[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in different embodiments may be combined with each other.

[0051] Through careful and in-depth research, the inventors of this case have provided a solution to the problems existing in the prior art. The utility model provides an automobile air-conditioning box and an automobile, wherein the automobile air-conditioning box includes: a shell, the shell having an air inlet and a face-blowing air duct opening, a flow channel formed between the air inlet and the face-blowing air duct opening; a blower motor, the blower motor being fixedly connected to a first side outside the shell, the blower motor having a drive shaft; a cross-flow fan, the cross-flow fan being located in the flow channel, the cross-flow fan being connected to the drive shaft, and the cross-flow fan having a working state of rotating based on the drive of the blower motor to drive the air in the flow channel to move from the air inlet to the face-blowing air duct opening. The automobile air-conditioning box and automobile of the utility model, by using a cross-flow fan with a simple structure, small mass, small volume and low cost to replace the existing centrifugal fan as the supercharging component of the automobile air-conditioning box, can optimize the component layout of the entire vehicle, reduce the mass of the entire vehicle, reduce the volume of the automobile air-conditioning box and reduce the manufacturing cost of the entire vehicle.

[0052] The above is the core concept of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention. The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0053] like Figure 1 、 Figure 2 and Figure 3 As shown, in one aspect, an embodiment of the present invention provides a vehicle air conditioning box, comprising: a housing 10 , a blower motor 20 and a cross-flow fan 30 .

[0054] Specifically, the housing 10 has an air inlet 11 and a face-blowing air duct 12, with a flow channel 13 formed between the air inlet 11 and the face-blowing air duct 12. The air in the automobile air conditioner flows in the flow channel 13 along the air inlet 11 toward the face-blowing air duct 12.

[0055] Specifically, the blower motor 20 is fixedly connected to the housing 10. It is located on a first side outside the housing 10, on the side of the flow passage 13 where air flows. The blower motor 20 cooperates with the arrangement of the crossflow fan 30 so that its own rotation drives the rotation of the crossflow fan 30. The blower motor 20 has a drive shaft for driving the crossflow fan 30.

[0056] Specifically, the cross-flow fan 30 is located in the flow channel 13 and between the air inlet 11 and the blowing air duct opening 12, so as to drive the air flow in the flow channel 13. The cross-flow fan 30 is connected to the drive shaft to receive the drive from the blower motor 20. The cross-flow fan 30 has a working state in which it rotates based on the drive of the blower motor 20 to drive the air in the flow channel 13 to move from the air inlet 11 to the blowing air duct opening 12. By using a cross-flow fan 30 with a simple structure, small mass and low cost to replace the existing centrifugal fan as the boost component of the automobile air-conditioning box, the component layout of the entire vehicle can be optimized, the mass of the entire vehicle can be reduced and the manufacturing cost of the entire vehicle can be reduced. In addition, the cross-flow fan 30 is smaller in size than the existing centrifugal fan, which can reduce the volume of the automobile air-conditioning box.

[0057] Continue to refer Figure 2 In some embodiments, the automobile air conditioning unit further includes a fan fixture 40. The fan fixture 40 is fixedly connected to a second side of the exterior of the housing 10, i.e., located on the side of the flow channel 13 opposite the blower motor 20. In other words, the fan fixture 40 and the blower motor 20 are respectively located on either side of the crossflow fan 30. The fan fixture 40 is connected to the crossflow fan 30 and, together with the blower motor 20, limits the crossflow fan 30, so that the crossflow fan 30 can only move in an axial rotational direction, thereby driving the air in the flow channel 13 from the air inlet 11 to the blowing surface air duct opening 12.

[0058] Continue to refer Figure 1 、 Figure 2 and Figure 3 In some embodiments, the housing 10 further includes a foot-blowing duct opening 14. The foot-blowing duct opening 14 is located between the air inlet 11 and the face-blowing duct opening 12 of the flow channel 13. The crossflow fan 30 also has an operating state in which it rotates, driven by the blower motor 20, to drive the air in the flow channel 13 from the air inlet 11 toward the foot-blowing duct opening 14. In other words, the crossflow fan 30 can pressurize air from the air inlet 11 and deliver it to the face-blowing duct opening 12 and the foot-blowing duct opening 14.

[0059] In some embodiments, the automobile air-conditioning box further comprises: a damper assembly (not shown in the figure). The damper assembly is located in the flow channel 13, and the damper assembly comprises a face damper and a foot damper. The face damper is close to the face air duct opening 12, and the foot damper is close to the foot air duct opening 14. The damper assembly is a wind direction adjustment and air volume control mechanism in the automobile air-conditioning box, and plays an important role in controlling the air volume and wind speed of the air outlet in the automobile air-conditioning box. The face damper is used to adjust the air volume and wind direction of the face air duct opening 12, and the foot damper is used to adjust the air volume and wind direction of the foot air duct opening 14.

[0060] like Figure 1 and Figure 4As shown, in some embodiments, the automobile air conditioning box further includes: a face-blowing actuator 51 and a foot-blowing actuator 52 .

[0061] Specifically, the face-blowing actuator 51 is located outside the housing 10, on the side of the flow channel 13 where air flows. It is connected to the face-blowing damper and controls the rotation of the damper. Furthermore, the face-blowing actuator 51 controls the air volume and speed at the face-blowing duct opening 12 based on its own rotation. In alternative embodiments, the face-blowing actuator 51 can also be located inside the housing 10 to reduce the size of the vehicle's air conditioning unit and minimize its overall space usage.

[0062] Specifically, the foot-blowing actuator 52 is located outside the housing 10, on the side of the flow channel 13 opposite the face-blowing actuator 51. The foot-blowing actuator 52 is connected to the foot-blowing damper and is configured to control the rotation of the foot-blowing damper. Furthermore, the foot-blowing actuator 52 controls the air volume and speed at the foot-blowing duct opening 14 based on its own rotation. In alternative embodiments, the foot-blowing actuator 52 can also be located within the housing 10 to reduce the size of the vehicle's air conditioning system and minimize its overall vehicle space usage.

[0063] Continue to refer Figure 1 and Figure 4 In some embodiments, the blower motor 20 is located on the side of the housing 10 closest to the driver's seat or the passenger seat. Because the blower motor 20 is located in the duct module of the vehicle's air conditioning unit, and the duct module is located between the driver's seat and the passenger seat, the blower motor 20 can be located near either side. This improves the flexibility of the vehicle's component layout without increasing the width and height of the vehicle's air conditioning unit's housing.

[0064] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in some embodiments, the cross-flow fan 30 has a plurality of integrally formed blades 31 and three annular partitions 32 arranged in sequence. The drive shaft of the blower motor 20 is fixedly connected to the partition 32 of the cross-flow fan 30 closest to the blower motor 20, thereby enabling the blower motor 20 to rotate and drive the cross-flow fan 30. Furthermore, the plurality of blades 31 are arranged in an upright ring between the sides of each two annular partitions 32, and the inclination directions of each two blades 31 are different, and the cross-section of the air flow direction of the blades 31 inside the flow channel 13 is arc-shaped, thereby achieving the air flow in the flow channel 13 driven by the rotation of the cross-flow fan 30 itself.

[0065] Continue to refer Figure 5 、 Figure 6、 Figure 7 and Figure 8 In some alternative embodiments, the extension direction of the blades 31 is parallel to the axial direction of the cross-flow fan 30 to facilitate the preparation of the cross-flow fan 30. In some alternative embodiments, the extension direction of the blades 31 forms an acute angle with the axial direction of the cross-flow fan 30 to improve the efficiency of the cross-flow fan 30 in driving air flow, which is not limited in this application.

[0066] Continue to refer Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the flow channel 13 includes two sub-flow channels 131 , with each fan blade 31 between two adjacent partitions 32 forming a corresponding air blowing structure. Specifically, the face-blowing air duct opening 12 may include a front face-blowing air duct opening 12 and a rear face-blowing air duct opening 12 . The two sub-flow channels 131 correspond to the front face-blowing air duct opening 12 and the rear face-blowing air duct opening 12 , respectively, for blowing air into the front and rear seats of the vehicle, respectively.

[0067] The automobile air-conditioning box of the present invention uses a cross-flow fan 30 with a simple structure, small mass, small volume and low cost to replace the existing centrifugal fan as the boost component of the automobile air-conditioning box, which can optimize the layout of the parts of the entire vehicle, reduce the mass of the entire vehicle, reduce the volume of the automobile air-conditioning box and reduce the manufacturing cost of the entire vehicle.

[0068] On the other hand, an embodiment of the present invention further provides a car, comprising the above-mentioned car air conditioning box. The specific technical solutions and technical effects of the car can be found in the above-mentioned embodiment of the car air conditioning box, and will not be repeated here.

[0069] In summary, the automobile air-conditioning box and automobile of the present invention, by using a cross-flow fan with simple structure, small mass, small volume and low cost to replace the existing centrifugal fan as the boost component of the automobile air-conditioning box, can optimize the layout of components of the entire vehicle, reduce the mass of the entire vehicle, reduce the volume of the automobile air-conditioning box and reduce the manufacturing cost of the entire vehicle.

[0070] The above content is a further detailed description of the present invention in conjunction with specific optional implementation methods, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
