Description

Technical Field

[0001] The present invention relates to the technical field of automobile ventilation, and in particular to an automobile roof ventilation system, a control method for the automobile roof ventilation system, and an automobile. Background Art

[0002] Based on the air outlet principle, there are currently two types of car roof vents: traditional vents and windless vents. Traditional roof vents adjust the air outlet angle by adjusting the grille blades. Typically, one vent is located at the top of the left and right sides of the second and third rows, and the vents in each of the four zones can be opened and closed independently. Furthermore, the styling of traditional vents limits the creativity of stylists. Windless vents utilize holes in the vent grille to disperse airflow, evenly distributing the temperature within the cabin and providing a softer, more air-conditioned airflow. This overcomes the drawback of traditional roof vents, which only direct air in a certain direction, resulting in uneven cabin temperatures.

[0003] However, the current windless ceiling air vents cannot achieve rapid cooling or heating in hot summer and cold winter. Compared with the traditional air outlet mode, passengers cannot feel the cooling or heating experience of large air volume. In addition, the existing windless air outlets are linked to the rear area and cannot control the opening and closing of the air outlets individually, which is easy to cause complaints and poor user experience, leading to user complaints and failing to bring users a good car experience. Summary of the Invention

[0004] The main purpose of the present invention is to propose a car roof ventilation system, a control method for the car roof ventilation system and a car, aiming to solve the problem that the existing roof windless air outlets cannot allow passengers to feel the large air volume cooling or heating experience, and the rear area is linked controlled and the opening and closing of the air outlets cannot be controlled separately.

[0005] To achieve the above-mentioned object, the automobile ceiling ventilation system proposed by the present invention comprises:

[0007] at least one auxiliary air duct, provided on one side of the main air duct in the longitudinal direction and extending in the transverse direction, one end of the auxiliary air duct being connected to the connecting air duct, the auxiliary air duct being provided with a first air outlet and a second air outlet spaced apart in the longitudinal direction; and

[0008] The blocking component includes a first blocking structure and a second blocking structure. The first blocking structure is arranged in the connecting air duct and is used to switch between the states of connecting and blocking the connecting air duct. The second blocking structure is used to switch between the states of connecting and blocking the first air outlet or the second air outlet.

[0009] In one embodiment, the auxiliary air duct includes a first air duct and a second air duct spaced apart in the transverse direction, the first air duct and the second air duct are both extended in the longitudinal direction and are connected to the connecting air duct, the first air duct is provided with the first air outlet, and the second air duct is provided with the second air outlet;

[0010] The second blocking structure is arranged in the connecting air duct and avoids the arrangement of the first blocking structure. The second blocking structure is used to connect or block the first air duct or the second air duct.

[0011] In one embodiment, the second blocking structure includes a second damper, one end of which is rotatably connected to the connecting air duct along an axis extending vertically, and the second damper is used to block or open the air inlet of the first air duct or the second air duct.

[0012] In one embodiment, the second blocking structure further includes a second drive motor, and the second drive motor is drivingly connected to the second damper to drive the second damper to rotate along an axis extending in a vertical direction and control a rotation angle of the second damper.

[0013] In one embodiment, the first blocking structure includes a first damper and a first drive motor, the first damper is rotatably arranged along an axis extending in the vertical direction, the first damper is used to connect or block the connecting air duct, and the first drive motor and the first damper are driven and connected to drive the first damper to rotate along the axis extending in the vertical direction and control the rotation angle of the first damper.

[0014] In one embodiment, both ends of the main air duct in the transverse direction are bent toward the longitudinal direction to form two connecting air ducts spaced apart in the transverse direction;

[0015] There are two auxiliary air ducts, which are arranged at intervals in the transverse direction, and one end of each of the two auxiliary air ducts is connected to the two connecting air ducts.

[0016] The present invention further provides a method for controlling a vehicle roof ventilation system. Based on the above-mentioned vehicle roof ventilation system, the method for controlling the vehicle roof ventilation system includes:

[0017] Obtain temperature regulation signal;

[0018] controlling the second blocking structure to block the second air outlet;

[0019] Obtaining the actual blocking time of the second air outlet;

[0020] If the actual blocking time reaches the preset blocking time, the second blocking structure is controlled to connect to the second air outlet.

[0021] In one embodiment, after the step of controlling the second blocking structure to connect to the second air outlet if the actual blocking time reaches the preset blocking time, the method further includes:

[0022] Get the air outlet mode switching signal;

[0023] According to the air outlet mode switching signal, the second blocking structure is controlled to block the first air outlet or the second air outlet.

[0024] In one embodiment, after the step of controlling the second blocking structure to connect to the second air outlet if the actual blocking time reaches the preset blocking time, the method further includes:

[0025] Get the air outlet switch signal;

[0027] The present invention further provides a car, comprising:

[0028] A vehicle ceiling ventilation system, such as the vehicle ceiling ventilation system described above; and

[0029] The control device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program is configured to implement the steps of the above-mentioned control method for the automobile roof ventilation system.

[0030] In the technical solution of the present invention, the state of the first blocking structure and the second blocking structure can be changed, so that the automobile ceiling ventilation system has a variety of air outlet modes. When the temperature of the second and third rows in the automobile cab is too high or too low, and the temperature of the second and third rows needs to be quickly lowered or raised, the first blocking structure is connected to the connecting air duct, and the second blocking structure blocks the second air outlet, so that the air inlet is only connected to the first air outlet. At this time, the air flow blown by the air conditioner can pass through the main air duct and the auxiliary air duct in sequence, and all be blown out from the first air outlet to achieve the purpose of quickly heating up or cooling the second and third rows of the automobile cab; when it is necessary to disperse the air flow blown by the air conditioner to various places in the second and third rows to achieve windless blowing and prevent the air conditioner from blowing directly, the first blocking structure is connected to the connecting air duct, and the second blocking structure connects the first air outlet and the second air outlet, so that The air inlet can be connected to the first air outlet and the second air inlet at the same time. At this time, the air flow blown out by the air conditioner can pass through the main air duct and the auxiliary air duct in sequence, part of the air flow is blown out from the first air outlet, and the remaining air flow is blown out from the second air outlet, so that the air flow blown out by the air conditioner can be blown out from multiple air outlets to achieve windless blowing; and when there is no passenger in the second row of the car cab and there is no need to adjust the temperature specifically, the first blocking structure is connected to the connecting air duct, and the second blocking structure blocks the first air outlet, so that the air inlet is only connected to the second air outlet. At this time, the air flow blown out by the air conditioner passes through the main air duct and the auxiliary air duct in sequence, and is all blown out from the second air outlet, avoiding cold air or hot air from blowing directly to the second row of the car cab, thereby causing waste; and when there is no need to adjust the temperature in the car cab, the first blocking structure blocks the connecting air duct, and neither the first air outlet nor the second air outlet blows out air. With such a configuration, the car roof ventilation system can achieve large-volume rapid cooling or heating functions, as well as windless blowing functions, and each air outlet can be controlled individually, and can switch to multiple air outlet modes according to the individual differences in temperature perception of passengers in the second and third rows of the car's cab, thereby meeting the needs of different groups of people as much as possible and improving user experience.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The present invention proposes a car roof ventilation system. It aims to solve the problem that existing roof-mounted windless air vents cannot provide passengers with a high-volume cooling or heating experience, and the rear area is controlled in a linked manner, making it impossible to control the opening and closing of the air vents individually.

[0046] It should be noted that the automobile roof ventilation system proposed in the present invention is generally applied to three-box automobiles.

[0047] See also Figure 1-3 In one embodiment of the present invention, the automobile ceiling ventilation system 100 includes a main air duct 1, at least one auxiliary air duct 2 and a blocking component 3, the main air duct 1 is extended in the transverse direction, an air outlet is provided on the main air duct 1, at least one end of the main air duct 1 in the transverse direction is bent toward the longitudinal direction to form a connecting air duct 12, the auxiliary air duct 2 is provided on one side of the main air duct 1 in the longitudinal direction and extends in the transverse direction, one end of the auxiliary air duct 2 is connected to the connecting air duct 12, the auxiliary air duct 2 is provided with a first air outlet 21 and a second air outlet 22 arranged at intervals in the longitudinal direction, the blocking component 3 includes a first blocking structure 31 and a second blocking structure 32, the first blocking structure 31 is provided in the connecting air duct 12, for switching between the states of connecting and blocking the connecting air duct 12, and the second blocking structure 32 is used to switch between the states of connecting and blocking the first air outlet 21 or the second air outlet 22.

[0048] In the technical solution of the present invention, the state of the first blocking structure 31 and the second blocking structure 32 can be changed to enable the automobile ceiling ventilation system 100 to have multiple air outlet modes. When the temperature of the second and third rows in the automobile cab is too high or too low and it is necessary to quickly lower or raise the temperature of the second and third rows, the first blocking structure 31 is connected to the connecting air duct 12, and the second blocking structure 32 blocks the second air outlet 22, so that the air inlet 11 is only connected to the first air outlet 21. At this time, the air flow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence and be blown out from the first air outlet 21 to achieve the purpose of quickly heating up or cooling the second and third rows of the automobile cab; when it is necessary to disperse the air flow blown out by the air conditioner to various places in the second and third rows to achieve windless blowing and prevent direct blowing of the air conditioner, the first blocking structure 31 is connected to the connecting air duct 12, and the second blocking structure is connected to connect the first air outlet 21 and the second air outlet 22, so that the inlet The air vent 11 can be connected to the first air outlet 21 and the second air inlet 11 at the same time. At this time, the air flow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence. Part of the air flow is blown out from the first air outlet 21, and the remaining air flow is blown out from the second air outlet 22, so that the air flow blown out by the air conditioner can be blown out from multiple air outlets to achieve a windless feeling. When there is no passenger in the second rear row in the car cab and there is no need to adjust the temperature specifically, the first blocking structure 31 is connected to the connecting air duct 12, and the The second blocking structure 32 blocks the first air outlet 21, so that the air inlet 11 is connected only to the second air outlet 22. At this time, the air flow blown out by the air conditioner passes through the main air duct 1 and the auxiliary air duct 2 in sequence, and is blown out entirely from the second air outlet 22, preventing cold or hot air from blowing directly to the second row of the vehicle's cab, thereby wasting air. When the temperature in the vehicle's cab does not need to be adjusted, the first blocking structure 31 blocks the connecting air duct 12, and neither the first air outlet 21 nor the second air outlet 22 blows out air. With this arrangement, the vehicle ceiling ventilation system 100 can achieve high-volume rapid cooling or heating functions, as well as a windless blowing function. Each air outlet can be individually controlled, and multiple air outlet modes can be switched based on the individual differences in temperature perception of passengers in the second and third rows of the vehicle's cab, thereby meeting the needs of different groups of people as much as possible and improving the user experience.

[0049] It can be understood that the present invention does not limit the specific number of the auxiliary air ducts 2. In one embodiment of the present invention, when there is only one auxiliary air duct 2, the first air outlet 21 corresponds to the rear space of the entire car cab, and the second air outlet 22 corresponds to the front space of the entire car cab.

[0050] In another embodiment of the present invention, the auxiliary air duct 2 can also be set to two, and the two auxiliary air ducts 2 are arranged at intervals along the transverse direction. Correspondingly, the two ends of the main air duct 1 along the transverse direction are bent toward the longitudinal direction to form two connecting air ducts 12 arranged at intervals in the transverse direction. Each connecting air duct 12 is connected to one auxiliary air duct 2, and the blocking component 3 includes two first blocking structures 31 and two second blocking structures 32. The two first blocking structures 31 and the two second blocking structures 32 are respectively arranged corresponding to the two auxiliary air ducts 2. In this way, the two first air outlets 21 correspond to the second air outlet of the car cab. In this embodiment, if there are two passengers sitting in the second row of the car's cab in the horizontal direction, the first passenger needs air-conditioning purge, while the second passenger does not need air-conditioning purge. At this time, the first blocking structure 31 corresponding to the first passenger is connected to the connecting air duct 12, and the second blocking structure 32 is at least connected to the first air outlet 21, so that the air flow blown out by the air conditioner can be directly blown to the position of the first passenger to meet the air-conditioning purge demand of the first passenger, and the first blocking structure 31 corresponding to the second passenger blocks the connecting air duct 12, thereby preventing the air flow blown out by the air conditioner from blowing to the position of the second passenger, meeting the need of the second passenger not to need air-conditioning purge.

[0051] Similarly, in this embodiment, if the first passenger wants a large amount of air blowing, while the second passenger only needs a senseless wind blowing, the first blocking structure 31 corresponding to the first passenger is connected to the connecting air duct 12, and the second blocking structure 32 closes the second air outlet 22, so that the airflow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence, and all blown out from the first air outlet 21, thereby achieving a large amount of air blowing for the first passenger's position, and the first blocking structure 31 corresponding to the second passenger is connected to the connecting air duct 12, and the second blocking connection connects the first air outlet 21 and the second air outlet 22, so that the air inlet 11 can be connected to the first air outlet 21 and the second air inlet 11 at the same time. At this time, the airflow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence, part of the airflow is blown out from the first air outlet 21, and the remaining airflow is blown out from the second air outlet 22, thereby achieving a senseless wind blowing for the second passenger.

[0052] In another embodiment of the present invention, three auxiliary air ducts 2 can be provided, and the three auxiliary air ducts 2 are arranged at intervals along the transverse direction. Accordingly, both ends of the main air duct 1 along the transverse direction are bent toward the longitudinal direction, and the middle part along the transverse direction is also convex toward the longitudinal direction to form the connecting air duct 12. The blocking component 3 includes three first blocking structures 31 and three second blocking structures 32. The three first blocking structures 31 and the second blocking structures 32 are respectively provided corresponding to the three auxiliary air ducts 2. With such a configuration, when the automobile roof ventilation system 100 needs to perform a senseless wind blowing, the airflow blown out by the air conditioner can be blown out from the three first air outlets 21 and the three second air outlets 22 at the same time, increasing the number of the first air outlets 21 and the second air outlets 22, thereby further reducing the flow rate of the airflow blown out of a single air outlet, further improving the effect of the senseless wind blowing, and optimizing the passenger's experience.

[0053] Of course, in other embodiments of the present invention, the auxiliary air duct 2 can also be set to other structural forms. During actual setting, it can be selected according to needs, and the present invention does not limit this.

[0054] It should be noted that in order to ensure the mutual independence of the first air outlet 21 and the second air outlet 22, and at the same time ensure that the closing or connection switching of the first air outlet 21 and the second air outlet 22 is achieved only through one second blocking structure 32, in one embodiment of the present invention, the auxiliary air duct 2 includes a first air duct 23 and a second air duct 24 spaced apart in the transverse direction, and the first air duct 23 and the second air duct 24 are both extended along the longitudinal direction and are connected to the connecting air duct 12 together, the first air outlet 21 is provided on the first air duct 23, and the second air outlet 22 is provided on the second air duct 24, the second blocking structure 32 is provided in the connecting air duct 12, and is arranged to avoid the first blocking structure 31, and the second blocking structure 32 is used to connect or block the first air duct 23 or the second air duct 24. In this way, when it is necessary to close the first air outlet 21 or the second air outlet 22, the second blocking structure 32 only needs to close the air inlet of the first air duct 23 or the second air duct 24 to isolate the first air duct 23 and the connecting air duct 12, or the second air duct 24 and the connecting air duct 12, thereby enabling the automobile roof ventilation system 100 to switch the air outlet mode.

[0055] In another embodiment of the present invention, the second blocking structure 32 can be movably arranged in the auxiliary air duct 2 along the longitudinal direction, and in the movable range of the second blocking structure 32, the second blocking structure 32 has a first position for blocking the first air outlet 21, a second position for blocking the second air outlet 22, and a third position for avoiding the first air outlet 21 and the second air outlet 22. In this way, when it is necessary to block the first air outlet 21, the second blocking structure 32 can be moved longitudinally to the first position; when it is necessary to block the second air outlet 22, the second blocking structure 32 can be moved longitudinally to the second position; when the first air outlet 21 and the second air outlet 22 both need to be connected to the air inlet 11, the second blocking mechanism can be moved to the third position.

[0056] Of course, in another embodiment of the present invention, the first air outlet 21 and the second air outlet 22 can be connected or blocked respectively through two structures. For example, the second blocking structure 32 can also be set as two wind shields, and the two wind shields are respectively set corresponding to the first air outlet 21 and the second air outlet 22, and each wind shield has a first state of closing the corresponding air outlet and a second state of revealing the corresponding air outlet. With such a setting, when it is necessary to connect the air inlet 11 and the first air outlet 21 or to connect the air inlet 11 and the second air outlet 22, it is only necessary to switch the corresponding wind shield to the second state of revealing the corresponding air outlet; when it is necessary to block the air duct between the air inlet 11 and the first air outlet 21 or to block the air duct between the air inlet 11 and the second air outlet 22, it is only necessary to switch the corresponding wind shield to the first state of closing the corresponding air outlet, which can also ensure the blocking performance of the second blocking structure 32.

[0057] In other embodiments of the present invention, the second blocking structure 32 may also be set as other structures that can connect or close the first air outlet 21 or the second air outlet 22. During actual setting, it can be selected according to needs, and the present invention does not impose any restrictions on this.

[0058] When the second blocking structure 32 blocks the first air duct 23 or the second air duct 24, the second blocking structure 32 may include a second damper 321. One end of the second damper 321 is rotatably connected to the connecting air duct 12 along an axis extending in the vertical direction. The second damper 321 is used to block or open the air inlet of the first air duct 23 or the second air duct 24. With this arrangement, when it is necessary to block the first air duct 23, the second damper 321 can be rotated along the axis extending in the vertical direction so that the second damper 321 covers the air inlet of the first air duct 23, thereby blocking the first air duct 23. When it is necessary to block the second air duct 24, the second damper 321 can be rotated along the axis extending in the vertical direction so that the second damper 321 covers the air inlet of the second air duct 24, thereby blocking the second air duct 24.

[0059] Of course, the present invention does not limit the specific form of the second air door 321. In another embodiment of the present invention, the second air door 321 can also be set as two plate sections that are spaced apart in the horizontal direction or up and down and can move in the direction of approaching or moving away from each other. In this way, the two plate sections can approach or move away from each other according to the needs of the occupants. When it is necessary to block the first air duct 23, the two plate sections can approach each other and move to the air inlet of the first air duct 23 at the same time, thereby covering the air inlet of the first air duct 23 and blocking the first air duct 23; when it is necessary to block the second air duct 24, the two plate sections can also be jointly covered at the air inlet of the second air duct 24 to block the second air duct 24; and when the first air duct 23 and the second air duct 24 are both to be connected to the connecting air duct 12, the two plate sections move away from each other to avoid the first air duct 23 and the second air duct 24, thereby realizing the connection between the first air duct 23 and the second air duct 24 and the connecting air duct 12.

[0060] Furthermore, when the second damper 321 is configured to rotate at one end along an axis extending in a vertical direction, the second blocking structure 32 further includes a second drive motor 322. The second drive motor 322 is drivably connected to the second damper 321 to drive the second damper 321 to rotate along the axis extending in the vertical direction and to control the rotation angle of the second damper 321. With this configuration, the second drive motor 322 can not only drive the second damper 321 to rotate along the axis extending in the vertical direction so that the second damper 321 blocks or opens the air inlet of the first air duct 23 or the second air duct 24, but can also adjust the rotation angle of the second damper 321, i.e., adjust the opening of the second damper 321, thereby adjusting the amount of air flowing from the air inlet 11 into the first air duct 23 or the second air duct 24, thereby further meeting the needs of the occupants and further improving the user experience.

[0061] Similarly, the present invention does not limit the specific blocking form of the first blocking structure 31. In one embodiment of the present invention, the first blocking structure 31 can be configured as two plate segments that are spaced apart in the horizontal direction or up and down, and can move in the direction of approaching or moving away from each other. In this way, the two plate segments can approach or move away from each other according to the needs of the occupants. When it is necessary to block the connecting air duct 12, the two plate segments can approach each other until they are tightly pressed together, thereby blocking the connecting air duct 12; when it is necessary to connect the connecting air duct 12, the two plate segments can move away from each other so that the airflow at the air inlet 11 can flow to the first air outlet 21 and the second air outlet 22.

[0062] In another embodiment of the present invention, the first blocking structure 31 includes a first damper 311, which is rotatably arranged along an axis extending in the vertical direction. The first damper 311 is used to connect or block the connecting air duct 12. In this configuration, when the first damper 311 is rotated along the axis extending in the vertical direction to extend in the longitudinal direction, a gap is formed between the first damper 311 and the sidewall of the connecting air duct 12, thereby achieving connection with the connecting air duct 12; when the first damper 311 is rotated along the axis extending in the vertical direction to extend in the transverse direction, the two ends of the first damper 311 abut against the sidewall of the connecting air duct 12, thereby blocking the connecting air duct 12.

[0063] When the first damper 311 is rotated along the axis extending in the vertical direction, the first blocking structure 31 further includes a first drive motor 312, which is drivably connected to the first damper 311 to drive the first damper 311 to rotate along the axis extending in the vertical direction and control the rotation angle of the first damper 311. With this configuration, the first drive motor 312 can not only drive the first damper 311 to rotate along the axis extending in the vertical direction so that the first damper 311 blocks or connects the connecting air duct 12, but can also adjust the rotation angle of the first damper 311, that is, adjust the opening of the first damper 311, thereby adjusting the amount of air flowing from the air inlet 11 into the connecting air duct 12, so as to further meet the needs of the passengers and further improve the user experience.

[0064] The present invention also proposes a control method for a vehicle ceiling ventilation system 100. Based on the above vehicle ceiling ventilation system 100, please refer to Figure 4 In a first embodiment of the present invention, the control method of the automobile ceiling ventilation system 100 includes:

[0065] S100, obtaining a temperature adjustment signal;

[0066] It can be understood that the temperature adjustment signal is a signal sent by the passenger, indicating that the temperature of the rear space in the cab needs to be adjusted.

[0067] It should be noted that the present invention does not limit the form in which the passenger sends the temperature adjustment signal. The passenger can send the temperature adjustment signal through the in-vehicle display screen, voice output, physical buttons or other methods.

[0068] S200, controlling the second blocking structure 32 to block the second air outlet 22;

[0069] It should be noted that when the temperature adjustment signal is received, the car roof ventilation system 100 will directly enter the large air volume rapid cooling / heating mode, that is, the second blocking structure 32 blocks the second air outlet 22, so that the air inlet 11 is only connected to the first air outlet 21. At this time, the air flow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in turn, and all blown out from the first air outlet 21, so as to achieve the purpose of quickly heating or cooling the rear space of the car cab.

[0070] S300: Obtaining the actual blocking time of the second air outlet 22;

[0071] By obtaining the actual blocking time, the working time of the automobile ceiling ventilation system 100 in the large air volume rapid cooling / heating mode can be determined, and then the temperature adjustment status of the current rear space of the cab can be judged.

[0072] S400 : If the actual blocking time reaches the preset blocking time, control the second blocking structure 32 to connect to the second air outlet 22 .

[0073] It can be understood that when the actual blocking time reaches the preset blocking time, it means that the rear space of the cab has completed rapid cooling / heating. At this time, the second blocking structure 32 is connected to the second air outlet 22, so that the air inlet 11 can be connected to the first air outlet 21 and the second air inlet 11 at the same time. At this time, the air flow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence, part of the air flow is blown out from the first air outlet 21, and the remaining air flow is blown out from the second air outlet 22, so that the air flow blown out by the air conditioner can be blown out from multiple air outlets, realizing windless blowing and improving the comfort of the rear passengers.

[0074] In the technical solution of this embodiment, when the temperature adjustment signal is received, the second blocking structure 32 is first controlled to block the second air outlet 22, so that the automobile roof ventilation system 100 enters a large air volume rapid cooling / heating mode, so that the air inlet 11 is only connected to the first air outlet 21. At this time, the air flow blown out by the air conditioner can pass through the main air duct 1 and the auxiliary air duct 2 in sequence, and all blown out from the first air outlet 21, so as to achieve the purpose of rapidly heating or cooling the rear space of the automobile cab. When the actual blocking time reaches the preset blocking time, the air flow is cooled. When the air conditioning system is blocked, indicating that rapid cooling or heating is no longer necessary, the second blocking structure 32 is controlled to connect to the second air outlet 22, allowing the air inlet 11 to connect to both the first air outlet 21 and the second air inlet 11. At this point, the air conditioning airflow can sequentially pass through the main air duct 1 and the auxiliary air duct 2, with part of the airflow being blown out of the first air outlet 21 and the remainder being blown out of the second air outlet 22. This allows the air conditioning airflow to be blown out from multiple air outlets, achieving a windless airflow and improving the comfort of rear passengers. This configuration allows for switching between multiple air outlet modes based on individual differences in passenger temperature perception, thereby meeting the needs of different groups and enhancing user experience.

[0075] See also Figure 5 In the second embodiment of the present invention, after step S400, the following steps are included:

[0076] S500: Obtain an air outlet mode switching signal;

[0077] It should be noted that the air outlet mode switching signal indicates that the passenger needs to switch the air outlet mode at this time to change the purge state of the automobile ceiling ventilation system 100.

[0078] S600 : Control the second blocking structure 32 to block the first air outlet 21 or the second air outlet 22 according to the air outlet mode switching signal.

[0079] For example, when there is only one auxiliary air duct 2, if the passenger does not need to blow air to the rear space, the second blocking structure 32 closes the first air outlet 21; if the passenger needs to blow a large amount of air to the rear space, the second blocking structure 32 closes the second air outlet 22; if the passenger needs to blow no-feel air to the rear space, the second blocking structure 32 connects the first air outlet 21 and the second air outlet 22.

[0080] When there are multiple auxiliary air ducts 2, if one of the passengers in the rear space needs to blow air and the other does not, then at this time, one of the second blocking structures 32 blocks the corresponding first air outlet 21, and the other second blocking structure 32 blocks the corresponding first air outlet 21 to achieve lateral one-sided blowing.

[0081] In the technical solution of this embodiment, it is first necessary to obtain the air outlet mode switching signal issued by the occupant, and then control the second blocking structure 32 to switch the first air outlet 21 or the second air outlet 22 on and off according to the air outlet mode switching signal, thereby realizing the switching of the air outlet mode of the automobile roof ventilation system 100.

[0082] See also Figure 6 In the third embodiment of the present invention, after step S400, the method further includes:

[0083] S500', obtaining the air outlet switch signal;

[0084] It can be understood that the air outlet switch signal is a signal sent by the passenger to switch the vehicle roof ventilation system 100 between the on and off states.

[0085] S600 ′, controlling the first blocking structure 31 to block the connecting air duct 12 .

[0086] It is understandable that when the occupant no longer needs to adjust the temperature in the cab, the first blocking structure 31 blocks the connecting air duct 12 , and neither the first air outlet 21 nor the second air outlet 22 blows out airflow.

[0087] In the technical solution of this embodiment, it is first necessary to obtain the air outlet switch signal sent by the occupant, and then control the first blocking structure 31 to block the connecting air duct 12, thereby closing the automobile roof ventilation system 100.
