When frost forms on the glass due to temperature difference between the cab and the outside of the cab, thereby affecting the driver's vision, the vehicle air-conditioning defrost duct structure of the present application can realize rapid air guidance, thereby guiding the airflow to blow to the vehicle glass, and realize the removal of the cold frost on the glass, thereby avoiding the influence of the cold frost on the vehicle glass on the driver's observation line; since the first air supply channel, the second air supply channel, the third air supply channel and the fourth air supply channel in the vehicle air-conditioning defrost duct structure of the present application are independent of each other, they can realize separate defrosting of the corresponding glasses. During the defrosting process, the driver or the co-driver does not need to adjust the air supply position of the defrost duct structure, thereby providing a guarantee for the driver to have an all-round clear and good driving vision.

[0018] 2. As a preferred embodiment of the present application, by setting a first partition plate and a second partition plate, on the one hand, the air supply channel is divided into an independent first air supply channel and a second air supply channel, and an independent third air supply channel and a fourth air supply channel, thereby realizing independent air outlet of the first air supply channel and the second air supply channel, and independent air outlet of the third air supply channel and the fourth air supply channel, so that each air supply channel can stably supply air to its corresponding glass for defrosting, thereby providing a guarantee for the stability of the driver's field of vision; on the other hand, the first partition plate and the second partition plate are used to separate the air supply channels, which simplifies the structural design of the vehicle air-conditioning defrost air duct structure, makes the manufacture of the vehicle air-conditioning defrost air duct structure simpler, and helps to reduce the production difficulty of the vehicle air-conditioning defrost air duct structure.

[0019] 3. As a preferred embodiment of the present application, since the driver mainly observes the field of vision through the front windshield in front of the main driver's seat and the co-driver's seat when driving, and observes the rearview mirrors and the side of the vehicle body through the side windshields on both sides of the main driver's seat and the co-driver's seat, high requirements are placed on the overall clarity of the glass in front of the main driver's seat and the co-driver's seat, while the glass on the left and right sides of the main driver's seat and the co-driver's seat mainly requires the clarity of the glass at the corresponding rearview mirror, and the requirement for the overall clarity of the glass is not very high in comparison. The first air supply port and the fourth air supply port are mainly used to defrost the glass at the corresponding rearview mirror; therefore, the cross-sectional area of ​​the first air inlet is set to be smaller than the cross-sectional area of ​​the second air inlet, and the cross-sectional area of ​​the fourth air inlet is set to be smaller than the cross-sectional area of ​​the third air inlet, so that the air conditioner can send more wind outward through the second air inlet and the third air inlet when the power is constant, so as to realize the overall defrosting of the front side glass of the main driver's seat and the co-driver's seat, realize the reasonable distribution of the air supply of the air conditioner, and improve the driver's front side field of vision perception range, thereby reducing the driver's field of vision obstruction.

[0020] 4. As a preferred embodiment of the present application, since the front side windows of the main driver's seat and the co-driver's seat have high requirements for the observation field of view, and the driver needs to observe the rearview mirror through the side windows, the clarity and defrosting speed of the windows on the left and right sides of the main driver's seat and the co-driver's seat are relatively high; and by providing the first arc-shaped guide portion, the airflow is gradually gathered and tightened in the first air supply channel under the guiding action of the first arc-shaped guide portion, the kinetic energy of the airflow is continuously enhanced under the convergence and tightening action of the airflow itself, and is ejected through the first air outlet, so that the left side window of the main driver's seat, especially the window corresponding to the rearview mirror, is quickly defrosted, and the airflow is in the second air supply channel The airflow is guided by the first arc-shaped guide portion.

[0053] like Figure 1As shown, a vehicle air conditioning defrost duct structure includes an air supply port 1 and an air supply channel connected to the air supply port 1, the air supply channel includes a first air supply channel 2, a second air supply channel 3, a third air supply channel 4 and a fourth air supply channel 5, the first air supply channel 2 has a first air outlet 6 toward the left side glass of the main driving seat of the vehicle body, the second air supply channel 3 has a second air outlet 7 toward the front side glass of the main driving seat of the vehicle body, the third air supply channel 4 has a third air outlet 8 toward the front side glass of the co-pilot seat of the vehicle body, and the fourth air supply channel 5 has a fourth air outlet 9 toward the right side glass of the co-pilot seat of the vehicle body.

[0054] The vehicle air-conditioning defrost duct structure of the present application is provided with a first air outlet 6, a second air outlet 7, a third air outlet 8 and a fourth air outlet 9, which can respectively realize air supply to the left side glass of the main driver's seat, the front side glass of the main driver's seat, the front side glass of the co-driver's seat and the right side glass of the co-driver's seat. When frost forms on the glass due to temperature difference between the cab and the outside of the cab, thereby affecting the driver's line of sight, the vehicle air-conditioning defrost duct structure of the present application can realize rapid air guidance, thereby guiding the airflow to blow to the vehicle glass, and realize the removal of the cold frost on the glass, thereby avoiding the influence of the cold frost on the vehicle glass on the driver's observation line of sight; since the first air supply channel 2, the second air supply channel 3, the third air supply channel 4 and the fourth air supply channel 5 in the vehicle air-conditioning defrost duct structure of the present application are independent of each other, they can realize separate defrosting of the corresponding glasses. During the defrosting process, the driver or the co-driver does not need to adjust the air supply position of the defrost duct structure, so as to provide a guarantee for the driver to have an all-round clear and good driving vision.

[0055] Preferably, an extension line of the line between the first air outlet 6 and the projection of the first air outlet 6 toward the left side glass of the main driver's seat passes through the left rearview mirror of the vehicle. This arrangement allows the first air outlet 6 to quickly defrost the left side glass of the corresponding left rearview mirror, giving priority to the driver observing the left rearview mirror through the left side glass.

[0056] Preferably, an extension line of the line between the fourth air outlet 9 and the projection of the fourth air outlet 9 toward the right side glass of the co-pilot seat passes through the right rearview mirror of the vehicle. This arrangement enables the fourth air outlet 9 to quickly defrost the right side glass corresponding to the right rearview mirror, giving priority to the driver to observe the right rearview mirror through the right side glass.

[0057] As a preferred implementation of the present application, Figure 1 As shown, it also includes a first partition plate 10 and a second partition plate 11 arranged in the air supply channel, the first partition plate 10 divides the air supply channel into the first air supply channel 2 and the second air supply channel 3, and the second partition plate 11 divides the air supply channel into the third air supply channel 4 and the fourth air supply channel 5.

[0058] By providing the first partition plate 10 and the second partition plate 11, on the one hand, the air supply channel is divided into an independent first air supply channel 2 and a second air supply channel 3, and an independent third air supply channel 4 and a fourth air supply channel 5, thereby realizing independent air outlet of the first air supply channel 2 and the second air supply channel 3, and independent air outlet of the third air supply channel 4 and the fourth air supply channel 5, so that each air supply channel can stably supply air to its corresponding glass for defrosting, thereby providing a guarantee for the stability of the driver's field of vision; on the other hand, the first partition plate 10 and the second partition plate 11 are used to separate the air supply channels, thereby simplifying the structural design of the vehicle air conditioning defrost duct structure, making the manufacture of the vehicle air conditioning defrost duct structure simpler, and helping to reduce the production difficulty of the vehicle air conditioning defrost duct structure.

[0059] As a preferred embodiment of this implementation, Figure 1 As shown, the first air supply channel 2 has a first air inlet 12 connected to the air supply port 1, the second air supply channel 3 has a second air inlet 13 connected to the air supply port 1, the cross-sectional area of ​​the first air inlet 12 is smaller than the cross-sectional area of ​​the second air inlet 13, the third air supply channel 4 has a third air inlet 14 connected to the air supply port 1, the fourth air supply channel 5 has a fourth air inlet 15 connected to the air supply port 1, and the cross-sectional area of ​​the fourth air inlet 15 is smaller than the cross-sectional area of ​​the third air inlet 14.

[0060] When driving, the driver mainly observes the field of vision through the front windshield in front of the main driver's seat and the co-driver's seat, and observes the rearview mirror and the side of the car body through the side windshields on both sides of the main driver's seat and the co-driver's seat. Therefore, higher requirements are placed on the overall clarity of the glass in front of the main driver's seat and the co-driver's seat, while the glass on the left and right sides of the main driver's seat and the co-driver's seat mainly requires the clarity of the glass at the corresponding rearview mirror. In comparison, the requirements for the overall clarity of the glass are not very high. The first air supply port 1 and the fourth air supply port 2 are Port 1 is mainly used to defrost the glass relative to the rearview mirror; therefore, the cross-sectional area of ​​the first air inlet 12 is set to be smaller than the cross-sectional area of ​​the second air inlet 13, and the cross-sectional area of ​​the fourth air inlet 15 is set to be smaller than the cross-sectional area of ​​the third air inlet 14, so that the air conditioner can send more wind outward through the second air inlet 13 and the third air inlet 14 when the power is constant, thereby realizing overall defrosting of the front side glass of the main driver's seat and the co-driver's seat, realizing a reasonable distribution of the air supply of the air conditioner, and improving the driver's front side field of vision perception range, thereby reducing the driver's field of vision obstruction.

[0061] As a preferred example under this embodiment, Figure 1As shown, the first partition plate 10 is provided with a first arc-shaped guide portion 16 at one end close to the air supply port 1, and the first arc-shaped guide portion 16 has a first concave surface 19 that is concave inwardly toward the first air supply channel 2 and a first convex surface 20 that is convex outwardly toward the second air supply channel 3, so that the first air inlet 12 is gradually tightened from the direction close to the air supply port 1 to the direction away from the air supply port 1, and the second air inlet 13 is gradually expanded from the direction close to the air supply port 1 to the direction away from the air supply port 1, and the second partition plate 11 is provided with a second arc-shaped guide portion 17 at one end close to the air supply port 1, and the second arc-shaped guide portion 17 has a second concave surface 21 that is concave inwardly toward the fourth air supply channel 5 and a second convex surface 22 that is convex outwardly toward the third air supply channel 4, so that the fourth air inlet 15 is gradually tightened from the direction close to the air supply port 1 to the direction away from the air supply port 1, and the third air inlet 14 is gradually expanded from the direction close to the air supply port 1 to the direction away from the air supply port 1.

[0062] Since the front side glass of the main driver's seat and the co-driver's seat has a higher requirement for the observation field of view, and the driver needs to observe the rearview mirror through the side glass, the clarity and defrosting speed of the left and right side glass of the main driver's seat and the co-driver's seat are required to be higher; and by providing the first arc-shaped guide portion 16, the airflow is gradually gathered and tightened in the first air supply channel 2 under the guiding action of the first arc-shaped guide portion 16, and the kinetic energy of the airflow is continuously enhanced under the convergence and tightening action of the airflow itself, and bursts out through the first air outlet 6, so that the left side glass of the main driver's seat, especially the position corresponding to the rearview mirror, is quickly defrosted, and the airflow in the second air supply channel 3 is guided by the first arc-shaped guide portion 16. The air gradually disperses under the air supply port 1, and after being sent out through the second air supply port 1, it can achieve uniform contact with the front side glass of the main driver's seat, realize the uniform defrosting rate of the front side glass of the main driver's seat, and improve the user's observation experience; in addition, the setting of the first arc-shaped guide portion 16 can guide the airflow when it moves from the air supply port 1 to the air supply channel, so that the airflow can slowly switch its direction of travel, reduce the violent collision of the airflow with the inner wall of the air supply channel due to the change of the direction of travel, thereby helping to reduce the kinetic energy loss of the airflow during the movement process, increase the airflow speed to the vehicle glass under the premise of constant air conditioning power consumption, and help improve the defrosting effect of the vehicle air conditioner. The setting of the second arc-shaped guide portion 17 is the same, which improves the movement rate of the airflow in the fourth air supply channel 5 and the diffusion uniformity in the third air supply channel 4, improves the uniformity of the defrosting rate of the front side glass of the main driver's seat and the local rapid defrosting of the right side glass of the main driver's seat, and reduces the kinetic energy loss of the airflow in the third air supply channel 4 and the fourth air supply channel 5.

[0063] This example does not limit the structural form of the first concave surface 19 and the second concave surface 21, and they can adopt any of the following methods:

[0064] Mode 1: The curvature of the first concave surface 19 gradually decreases from the direction close to the air supply port 1 to the direction away from the air supply port 1. In this way, the cross-sectional area of ​​the first air supply channel 2 corresponding to the first arc-shaped guide portion gradually decreases, and the degree of convergence of the airflow at the first concave surface 19 in the first air supply channel 2 gradually increases, so that the airflow can be ejected from the first air outlet 6 more quickly, so as to realize the rapid defrosting of the left side glass of the main driver's seat.

[0065] Mode 2: The curvature of the second concave surface 21 gradually decreases from the direction close to the air supply port 1 to the direction away from the air supply port 1. In this way, the cross-sectional area of ​​the fourth air supply channel 5 corresponding to the second arc-shaped guide portion gradually decreases, and the degree of convergence of the airflow at the second concave surface 21 in the fourth air supply channel 5 gradually increases, so that the airflow can be ejected from the fourth air outlet 9 more quickly, so as to realize the rapid defrosting of the right side glass of the co-pilot seat.

[0066] Method 3: If Figure 1 As shown, the curvature of the first concave surface 19 gradually decreases from the direction close to the air supply port 1 to the direction away from the air supply port 1, and the curvature of the second concave surface 21 gradually decreases from the direction close to the air supply port 1 to the direction away from the air supply port 1. In this way, the cross-sectional area of ​​the first air supply channel 2 corresponding to the first arc-shaped guide portion gradually decreases, and the degree of convergence of the airflow at the first concave surface 19 in the first air supply channel 2 gradually increases, so that it can be ejected from the first air outlet 6 more quickly to achieve rapid defrosting of the left side glass of the main driver's seat; at the same time, the cross-sectional area of ​​the fourth air supply channel 5 corresponding to the second arc-shaped guide portion gradually decreases, and the degree of convergence of the airflow at the second concave surface 21 in the fourth air supply channel 5 gradually increases, so that it can be ejected from the fourth air outlet 9 more quickly to achieve rapid defrosting of the right side glass of the co-pilot's seat.

[0067] As a preferred implementation of the present application, Figure 1As shown, the air supply channel is further provided with a third arc-shaped guide portion 18 for separating the second air supply channel 3 from the third air supply channel 4. By providing the third arc-shaped guide portion 18, the airflow can be relatively smoothly divided under the guidance of the third arc-shaped guide portion 18 when it is sent out from the air supply port 1 and sent to the second air supply channel 3 and the third air supply channel 4 respectively, thereby reducing the kinetic energy loss caused by factors such as collision when the airflow is divided; at the same time, the third arc-shaped guide portion 18 can also guide the direction of the airflow, so that the airflow can slowly change its direction of travel in the second air supply channel 3 and the third air supply channel 4 respectively, further reducing the kinetic energy loss of the airflow due to collision with the inner walls of the second air supply channel 3 and the third air supply channel 4, and when the air supply power of the air conditioner is constant, the kinetic energy of the airflow to be sent out from the second air supply channel 3 and the third air supply channel 4 is increased.

[0068] As a preferred embodiment of this implementation, Figure 1 As shown, the third arc-shaped guide portion 18 is in a U-shaped structure, and the third arc-shaped guide portion 18 has a dividing end 23 protruding toward the air outlet 1. By providing the dividing end 23, the third arc-shaped guide portion 18 can better divide the airflow, reduce the kinetic energy loss generated when the airflow collides with the third arc-shaped guide portion 18, and help improve the delivery power of the airflow.

[0069] The present application does not limit the structural form of the first air supply channel 2 and the fourth air supply channel 5, and they may adopt any of the following embodiments:

[0070] Embodiment 1: The first air supply channel 2 is provided with a first bending portion near the first air outlet 6, and the first bending portion guides the first air supply channel 2 to deflect toward the left side glass of the main driving seat of the vehicle body. By providing the first bending portion, the movement direction of the airflow in the first air supply channel 2 can be guided to deflect toward the left side glass of the main driving seat, thereby achieving defrosting of the left side glass of the main driving seat, reducing the requirements for the extension direction of the first air supply channel 2, and optimizing the structural design of the defrosting air duct structure of the vehicle air conditioner.

[0071] Embodiment 2: The fourth air supply channel 5 is provided with a second bending portion near the fourth air outlet 9, and the second bending portion guides the fourth air supply channel 5 to deflect toward the right side glass of the passenger seat of the vehicle body. By providing the second bending portion, the movement direction of the airflow in the fourth air supply channel 5 can be guided to deflect toward the right side glass of the passenger seat, thereby achieving defrosting of the right side glass of the passenger seat, reducing the requirements for the extension direction of the fourth air supply channel 5, and optimizing the structural design of the defrosting air duct structure of the vehicle air conditioner.

In this way, the airflow sent out between the second air outlet 7 and the third air outlet 8 can be evenly distributed to the front side glass of the main driver's seat and the front side glass of the co-driver's seat, so that the driver can obtain a full and clear view of the front, and the defrosting effect of the air conditioner is improved. Figure 1 Where L1 refers to the distance between the second air outlet 7 and the third air outlet 8, L2 refers to the distance between the first air outlet 6 and the fourth air outlet 9, and 32%≤L1 / L2≤37%.

[0074] like Figure 2 As shown, a vehicle air conditioner includes the vehicle air conditioner defrosting air duct structure as described above. The vehicle air conditioner of the present application can realize synchronous defrosting of the front side and left side glass of the main driver's seat and the front side and right side glass of the co-driver's seat, with uniform air output, and can meet the defrosting demand without the driver adjusting the air outlet position of the air conditioner, thereby improving the driving experience of the vehicle driver.
