Description

Technical Field

[0001] This invention relates to the field of vehicle air conditioning system technology, and in particular to a vehicle air conditioning foot blowing structure and vehicle. Background Technology

[0002] Currently, in vehicle air conditioning systems, the air conditioning ventilation system, composed of air ducts and air vents, is responsible for delivering the airflow, which has been humidified and purified, to the vehicle's cabin to perform functions such as ventilation, cooling, heating, defrosting, defogging, and air purification. Among these, the foot vents are located in an area not visible to the occupants, and their main function is singular. Because they cannot be integrated with the second-row air ducts, the ventilation path is long, resulting in poor air conditioning performance for the second-row air vents. Summary of the Invention

In the first operating condition, the air guide plate rotates to block the air duct between the air inlet and the connecting air outlet, and the air inlet and the foot blower outlet are connected; in the second operating condition, the driving member drives the air guide plate to rotate to block the air duct between the air inlet and the foot blower outlet, and the air inlet and the connecting air outlet are connected; in the third operating condition, the driving member drives the air guide plate to rotate to avoid the air duct between the foot blower outlet, the connecting air outlet and the air inlet, and the foot blower outlet and the connecting air outlet are both connected to the air inlet.

[0005] As an optional technical solution for the air conditioning foot blowing structure of a vehicle, the air guide plate includes a rotating shaft and a plate body. The plate body and the rotating shaft are connected. The rotating shaft is rotatably disposed on the air outlet housing. The driving component is connected to the rotating shaft to drive the plate body to rotate.

[0006] As an optional technical solution for the air conditioning foot blowing structure of a vehicle, the driving component includes a drive motor and a connecting crank. The drive motor is mounted on the air outlet housing, and the output shaft of the drive motor is connected to the air guide plate through the connecting crank.

[0007] As an optional technical solution for the vehicle air conditioning foot blowing structure, the vehicle air conditioning foot blowing structure further includes a first sealing element and a second sealing element. The first sealing element is bonded to the air outlet housing and located at the air inlet, and the second sealing element is bonded to the air outlet housing and located at the transition air outlet.

[0008] As an optional technical solution for the air conditioning foot blowing structure of a vehicle, the shape of the first seal matches the shape of the air inlet, and the shape of the second seal matches the shape of the transition air outlet.

[0009] As an optional technical solution for the vehicle air conditioning foot blowing structure, both the first seal and the second seal are sealing rings.

[0010] As an optional technical solution for the vehicle air conditioning foot blowing structure, the vehicle air conditioning foot blowing structure also includes foam, which is adhered to the bottom of the air outlet housing.

[0011] As an optional technical solution for the air conditioning foot blowing structure of a vehicle, the air outlet housing includes an upper housing and a lower housing connected to each other.

[0012] As an optional technical solution for the vehicle air conditioning foot blowing structure, the vehicle air conditioning foot blowing structure also includes an air outlet grille, which is snapped onto the upper housing and covers the air outlet.

[0013] On the other hand, the present invention provides a vehicle including the vehicle air conditioning foot blowing structure of any of the above-mentioned solutions.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention provides a vehicle air conditioning foot blowing structure, which includes an air outlet housing and an air guide adjustment component. The air outlet housing has an air inlet, a foot blowing outlet, and a connecting air outlet; the air guide adjustment component includes an air guide plate and a driving component. The vehicle air conditioning foot blowing structure of this invention is provided with an air inlet, a foot blowing outlet, and a connecting air outlet. The connecting air outlet can connect to other air ducts to achieve multiple airflow points.

Similarly, in the second operating condition, the driving component drives the air guide plate to rotate, causing the air guide plate to block the air inlet and the connecting air outlet. The air duct between the foot-blowing air outlets connects the air inlet and the connecting air outlet. Since the connecting air outlet can connect to other air ducts to achieve multiple airflow points, it allows for connection of air ducts with different needs to the connecting air outlet, thus achieving multi-functional airflow. Similarly, in the third operating mode, the drive component rotates the air guide plate, causing it to avoid the air duct between the foot-blowing air outlet, the connecting air outlet, and the air inlet, thereby ensuring that both the foot-blowing air outlet and the connecting air outlet are connected to the air inlet, thus meeting different user needs. The vehicle air conditioning foot-blowing structure of this invention effectively solves the problem of the single function of existing vehicle air conditioning foot-blowing structures; it can also be integrated with the second-row airflow duct in the vehicle, shortening the ventilation path and thus improving the air conditioning performance of the second-row airflow.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 8 As shown, this embodiment provides a vehicle air conditioning foot blowing structure, which includes an air outlet housing 1 and an air guide adjustment component 2. The air outlet housing 1 has an air inlet 11, a foot blowing air outlet 12, and a connecting air outlet 13, and can be installed on a vehicle carpet. The air guide adjustment component 2 includes an air guide plate 21 and a driving component 22. The air guide plate 21 is rotatably disposed on the air outlet housing 1, and the driving component 22 is installed on the air outlet housing 1. The driving component 22 and the air guide plate 21 are drivenly connected to drive the air guide plate 21 to rotate. The vehicle air conditioning foot blowing structure has a first working condition, a second working condition, and a third working condition. In the first working condition, the driving component 22 drives the air guide plate 21 to rotate, thereby causing the air guide plate 21 to rotate. In the first working condition, the air inlet 11 and the transition air outlet 13 are blocked, and the air inlet 11 and the foot blower outlet 12 are connected. In the second working condition, the driving component 22 drives the air guide plate 21 to rotate so that the air guide plate 21 blocks the air inlet 11 and the foot blower outlet 12, and the air inlet 11 and the transition air outlet 13 are connected. In the third working condition, the driving component 22 drives the air guide plate 21 to rotate so that the air guide plate 21 avoids the air inlet 11 between the foot blower outlet 12, the transition air outlet 13 and the air inlet 13, and the foot blower outlet 12 and the transition air outlet 13 are both connected to the air inlet 11.

[0035] The vehicle air conditioning foot-blowing structure of the present invention includes an air inlet 11, a foot-blowing air outlet 12, and a connecting air outlet 13. The connecting air outlet 13 can connect to other air ducts to achieve multiple airflow points. In the first operating condition, the driving component 22 drives the air guide plate 21 to rotate, causing the air guide plate 21 to block the air duct between the air inlet 11 and the connecting air outlet 13, thereby connecting the air inlet 11 and the foot-blowing air outlet 12, thus achieving the foot-blowing function. Similarly, in the second operating condition, the driving component 22 drives the air guide plate 21 to rotate, causing the air guide plate 21 to block the air inlet 11. The air duct between the foot air outlet 12 and the air inlet 11 is connected to the connecting air outlet 13. Since the connecting air outlet 13 can connect to other air ducts to achieve multiple airflow points, air ducts with different needs can be connected to the connecting air outlet 13, thereby achieving multi-functional airflow. Similarly, when in the third working condition, the driving component 22 drives the air guide plate 21 to rotate, so that the air guide plate 21 avoids the air duct between the foot air outlet 12, the connecting air outlet 13 and the air inlet 11, thereby achieving that the foot air outlet 12 and the connecting air outlet 13 are both connected to the air inlet 11, thus meeting different user needs. The vehicle air conditioning foot air outlet structure of the present invention effectively solves the problem of the single function of the vehicle air conditioning foot air outlet structure in the prior art; at the same time, it can also be integrated with the second row airflow duct in the vehicle, shortening the ventilation path, thereby improving the air conditioning performance of the second row airflow.

[0036] In some embodiments, the air guide plate 21 includes a rotating shaft 211 and a plate body 212. The plate body 212 and the rotating shaft 211 are connected, and the rotating shaft 211 is rotatably disposed in the air outlet housing 1. The driving member 22 and the rotating shaft 211 are connected in a transmission manner, thereby achieving the purpose of driving the plate body 212 to rotate through the driving member 22.

[0037] In this embodiment, the driving component 22 includes a drive motor 221 and a connecting crank 222. The drive motor 221 is mounted on the air outlet housing 1, and its output shaft is connected to the air guide plate 21 via the connecting crank 222. This allows the drive motor 221 to drive the air guide plate 21 to rotate.

[0038] Optionally, the output shaft of the drive motor 221 is plugged into one end of the connecting crank 222, and the other end of the connecting crank 222 is plugged into the air guide plate 21.

[0039] In some embodiments, the vehicle air conditioning blower structure further includes a first seal 31 and a second seal 32. The first seal 31 is adhered to the air outlet housing 1 and located at the air inlet 11, thereby sealing the air inlet 11; similarly, the second seal 32 is adhered to the air outlet housing 1 and located at the transition air outlet 13, thereby also sealing the transition air outlet 13.

[0040] Furthermore, the shape of the first seal 31 matches the shape of the air inlet 11, which allows it to fit better with the air inlet 11 and ensure a sealing effect; similarly, the shape of the second seal 32 matches the shape of the transition air outlet 13, which allows it to fit better with the transition air outlet 13 and ensure a sealing effect.

[0041] In this embodiment, both the first sealing element 31 and the second sealing element 32 are sealing rings, which have stable sealing performance and are easy to install and disassemble.

[0042] In some embodiments, the vehicle air conditioning blower structure also includes foam 4, which is bonded to the bottom of the air outlet housing 1 to provide support and fixation.

[0043] Specifically, the air outlet housing 1 includes an upper housing 14 and a lower housing 15 connected to each other. The upper housing 14 has an air inlet 11 and a foot-blowing air outlet 12. The upper housing 14 and the lower housing 15 are arranged to form a transition air outlet 13. The air guide plate 21 is rotatably disposed on the lower housing 15, and the driving component 22 is installed on the lower housing 15.

[0044] Furthermore, the vehicle's air conditioning foot-blowing structure also includes an air vent grille 5, which is snapped onto the upper housing 14 and covers the foot-blowing air vent 12. This prevents impurities from entering the interior of the foot-blowing air vent 12.

[0045] like Figure 3 and Figure 4 As shown, it can be seen that under the first working condition, the air inlet 11 and the air outlet 12 of the vehicle's air conditioning foot blowing structure blow air and the air guide plate 21 abuts against the inner wall of the lower housing 15 to block the air duct between the air inlet 11 and the connecting air outlet 13.

[0046] like Figure 5 and Figure 6 As shown, it can be seen that under the second working condition, the air inlet 11 and the connecting air outlet 13 of the vehicle air conditioning foot blowing structure blow air and the air guide plate 21 abut against the inner wall of the upper housing 14 to block the air duct between the air inlet 11 and the foot blowing air outlet 12.

[0047] like Figure 7 and Figure 8 As shown, it can be seen that under the third operating condition, the airflow of the air inlet 11, the air outlet 12, and the connecting air outlet 13 of the vehicle's air conditioning foot blowing structure, as well as the air guide plate 21, does not contact the inner wall of the upper housing 14 and the inner wall of the lower housing 15.

[0048] Optionally, the present invention can be implemented by touching the central control screen of the vehicle. The central control screen converts the operation into a control signal, which is transmitted to the intelligent area controller (PDC) through the control unit (VDC) of the intelligent vehicle control platform. The intelligent area controller (PDC) converts the control signal into a LIN signal acceptable to the motor driver. After receiving the corresponding instruction, the motor LIN chip sends a pulse to control the motor to rotate, thereby driving the air guide plate to rotate, realizing the adjustment of three working conditions, namely the first working condition: air blowing from the foot air outlet 12, air blowing from the transfer air outlet 13, and air blowing from the air inlet 11, foot air outlet 12, and transfer air outlet 13 simultaneously.

[0049] This embodiment also provides a vehicle including the foot-blowing structure of the vehicle air conditioning system described above. The vehicle using this invention is equipped with an air inlet 11, a foot-blowing outlet 12, and a connecting outlet 13. The connecting outlet 13 can be connected to other air ducts to achieve multiple airflow points. In the first operating condition, the driving component 22 drives the air guide plate 21 to rotate, causing the air guide plate 21 to block the air duct between the air inlet 11 and the connecting outlet 13, thereby connecting the air inlet 11 and the foot-blowing outlet 12, thus achieving the foot-blowing function. Similarly, in the second operating condition, the driving component 22 drives the air guide plate 21 to rotate, causing the air guide plate 21 to block the air inlet 11 and the foot-blowing outlet 12. The air duct between the air outlets 12 connects the air inlet 11 and the connecting air outlet 13. Since the connecting air outlet 13 can connect to other air ducts to achieve multiple airflow points, air ducts with different needs can be connected to the connecting air outlet 13, thereby achieving multi-functional airflow. Similarly, in the third working condition, the driving component 22 drives the air guide plate 21 to rotate, so that the air guide plate 21 avoids the air duct between the foot air outlet 12, the connecting air outlet 13 and the air inlet 11, thereby achieving that the foot air outlet 12 and the connecting air outlet 13 are both connected to the air inlet 11, thus meeting different user needs. The vehicle using the present invention effectively solves the problem of the single function of the existing vehicle air conditioning foot air outlet structure; at the same time, it can also be integrated with the second row airflow duct in the vehicle, shortening the ventilation path and thus improving the air conditioning performance of the second row airflow.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
