Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to an integrated air outlet device for automotive air conditioning. Background Technology

[0002] In the existing technology, the structure of an automotive air conditioning system typically includes a blower assembly, an evaporator, a heater, and an air supply device. Its main function is to guide the air supplied by the blower through the evaporator for cooling and the heater for temperature adjustment, and then guide the air supply device to various air outlet areas in the cabin to regulate the temperature and airflow of the air inside the vehicle.

[0003] This type of air conditioning structure is widely used in traditional passenger cars and other models with relatively ample space, and the assembly area is usually located below the dashboard or inside the cabin.

[0004] However, as the market's demand for comfort and driving experience continues to increase, more and more small vehicles, such as tricycles and electric microcars, are also gradually demanding air conditioning system configurations, especially in summer environments where the need for cooling functions is particularly prominent.

[0005] Due to the compact size and limited interior space of such vehicles, the existing split-type air conditioning structure has obvious shortcomings in terms of structural layout and spatial adaptability, making it difficult to achieve effective integration within the limited dashboard or cabin space.

[0006] Therefore, there is an urgent need to provide an integrated air outlet device for automotive air conditioning that is compact, highly integrated, and suitable for small vehicles. Utility Model Content

[0007] This utility model addresses the shortcomings of existing technologies by proposing an integrated air outlet device for automotive air conditioning, the specific technical solution of which is as follows: An integrated air outlet device for automotive air conditioning, characterized in that: Includes the main structure, blower, heater, regulating mechanism, flow divider, and air guide plate; The main structure internally defines a main chamber, and the main structure is provided with an air inlet and an air outlet. The main chamber is divided into an air inlet chamber, a heating chamber, and an air outlet chamber along the airflow direction. The blower is fixed in the air inlet chamber; The heater is fixedly connected to the heating chamber. The diverter plate is disposed at the air outlet to divide the air outlet into a first air outlet area and a second air outlet area; One side of the air guide plate is hinged to the flow divider plate, and the adjustment mechanism is used to drive the air guide plate to rotate so that the airflow is directed to the first air outlet area or the second air outlet area.

[0008] To better realize this utility model, it can be further made as follows: The adjustment mechanism is located on the outer wall of the air outlet chamber. A connecting shaft is provided on the inner side of the air guide plate. The air guide plate is hinged to the flow divider plate through the connecting shaft. The driving part of the adjustment mechanism extends into the interior of the air outlet chamber and is connected to the connecting shaft to drive the air guide plate to rotate around the hinge point.

[0009] Furthermore, the adjustment mechanism is an adjustment motor.

[0010] Furthermore, the main structure includes a first shell and a second shell, which are assembled together to form the main chamber.

[0011] Furthermore, the first housing and the second housing are connected by bolts.

[0012] Furthermore: the air outlet is connected to an air outlet pipe, the inner end of the air outlet pipe is connected to the air outlet, and the outer end is provided with an outward flare structure; The air outlet duct is equipped with a partition plate, which divides the air outlet duct into a first air outlet duct and a second air outlet duct in the horizontal direction. The first air outlet duct is connected to the first air outlet area, and the second air outlet duct is connected to the second air outlet area.

[0013] The beneficial effects of this utility model are as follows: First, this utility model defines a main chamber within the main structure and divides it into an air inlet chamber, a heating chamber, and an air outlet chamber along the airflow direction. This integrates the blower, heater, and air supply path within the same cavity structure, resulting in a compact overall layout. This effectively reduces the space occupied by traditional split-type arrangements and improves the system integration of this utility model in small vehicles.

[0014] Secondly, by dividing the air outlet into a first air outlet zone and a second air outlet zone using a diverter plate, and in conjunction with the set air guide plate and the adjustment mechanism for driving the rotation of the air guide plate, dynamic switching control of the airflow direction is achieved. Compared with traditional air conditioning outlet devices with fixed air supply paths, this structure can directionally guide cold / warm airflow to different areas.

[0015] Third, the adjustment mechanism is located on the outer wall of the air outlet chamber, and the drive unit extends into the chamber and connects to the air guide plate, which can avoid complex wiring and motor obstruction in the internal space of the whole machine, and improve the rationality of the layout and the convenience of maintenance.

[0016] Fourth, the main structure of this utility model is formed by assembling the first shell and the second shell and using bolt connection, which facilitates assembly and disassembly and is beneficial to modular manufacturing and later maintenance of the product.

[0017] Fifth, the air outlet is connected to an air outlet duct, which is internally equipped with a partition plate. The resulting first and second air outlet ducts are connected to the first and second air outlet areas within the main cavity, respectively. This structure continues the flow distribution structure within the cavity, ensuring consistent airflow guidance and sealing, improving air delivery efficiency, and simplifying downstream piping layout. Especially in small vehicle bodies, this structure makes it easier to achieve integrated installation, avoiding the problems of airflow turbulence or leakage at the connection points of traditional air outlet structures.

They are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 5As shown, this utility model embodiment provides an integrated air outlet device for automotive air conditioning, including a main structure 1, a blower 9, a heater 10, an adjustment mechanism, a flow divider 12, and an air guide plate 13.

[0022] The main structure 1 internally defines a main chamber, which is divided into an air inlet chamber 4, a heating chamber 5, and an air outlet chamber 6 along the airflow direction.

[0023] The main structure 1 is formed by the assembly of the first shell 2 and the second shell 3. The first shell 2 and the second shell 3 are connected by bolts. Specifically, the edges of the two shells are provided with mounting holes for bolts to pass through and fix, ensuring that the main chamber structure is sealed and secure as a whole and is easy to install and maintain.

[0024] The main structure 1 is provided with an air inlet 7, and the main structure 1 is connected to the evaporator structure on one side of the air inlet 7. The evaporator is a heat exchange component in the vehicle air conditioning system, and its air outlet is arranged facing the air inlet 7 and is in communication with the air inlet 7. When the evaporator is working, the cooled airflow directly enters the air inlet 7 from the air outlet, and then enters the air intake chamber 4 and is drawn in by the blower 9.

[0025] When cooling is not required, the evaporator stops heat exchange and continues to draw ambient airflow as an air passage. Ambient air can still enter the air intake chamber 4 through this area, thereby achieving continuous air intake in cooling, non-cooling and heating states, ensuring the stable operation of the air conditioning system under different operating conditions.

[0026] The blower 9 is installed inside the air inlet chamber 4. The blower 9 preferably uses an existing, mature centrifugal fan assembly and is fixed to the inner wall mounting position of the main structure 1 with screws. The air outlet of the blower 9 faces the heating chamber 5 to ensure that the airflow is stably propelled in the predetermined direction.

[0027] The heater 10 is installed inside the heating chamber 5. The heater 10 is a commonly used PTC electric heater 10. The heater 10 is fixed to the inner wall of the heating chamber 5 by positioning screws. The power lead passes through the outer shell of the main structure 1 for easy connection to the vehicle power supply system.

[0028] An air outlet 8 is provided at the end of the air outlet chamber 6. A diverter plate 12 is installed at the air outlet 8, dividing the air outlet 8 into a first air outlet zone 18 and a second air outlet zone 19 to achieve dual-zone air supply function. The inner side of the air guide plate 13 is rotatably connected to the diverter plate 12. Specifically, the inner side of the air guide plate 13 is provided with a connecting shaft 14, and the air guide plate 13 is hinged to the diverter plate 12 through the connecting shaft 14.

[0029] The adjustment mechanism is located on the outer wall of the air outlet chamber 6, and the adjustment mechanism adopts the existing adjustment motor 11 that is adapted to the compact structure installation requirements.

[0030] The regulating motor 11 is fixed to the mounting surface of the outer wall of the air outlet chamber 6 by screws. The output shaft of the regulating motor 11 passes through the shaft hole on the housing of the air outlet chamber 6 and extends into the cavity to connect with the connecting shaft 14. It is used to drive the air guide plate 13 to rotate around the hinge point, thereby adjusting the guiding path of the airflow. When the airflow needs to enter the first air outlet zone 18, the regulating motor 11 drives the air guide plate 13 to rotate in the first direction, so that the air guide plate 13 closes the entrance of the second air outlet zone 19, and the airflow can only pass through the first air outlet zone 18.

[0031] When airflow needs to enter the second air outlet zone 19, the regulating motor 11 drives the air guide plate 13 to rotate in the opposite direction, so that the air guide plate 13 closes the entrance of the first air outlet zone 18, and the airflow can only pass through the second air outlet zone 19.

[0032] The air outlet 8 is connected to an air outlet pipe 15, which is sealed to the air outlet 8 via a threaded connection. The inner end of the air outlet pipe 15 communicates with the air outlet 8, and the outer end has an outwardly flared structure 16 for connecting to the vehicle's air distribution system. An internal partition plate 17 is provided in the air outlet pipe 15, dividing it laterally into a first air outlet pipe 20 and a second air outlet pipe 21, thus creating independent air supply channels.

[0033] The first air outlet duct 20 is connected to the first air outlet zone 18, and the second air outlet duct 21 is connected to the second air outlet zone 19.

[0034] During the operation of this device, when cooling is required, the evaporator turns on and cools the incoming air. The cooled airflow enters the air inlet 7 of the main structure 1 directly through the evaporator outlet, and then flows sequentially through the air inlet chamber 4 and the heating chamber 5 before entering the air outlet chamber 6. The regulating motor 11 drives the air guide plate 13 to rotate according to the control signal of the vehicle air conditioning control system, thereby guiding the airflow to the first air outlet zone 18 or the second air outlet zone 19. The airflow enters the air outlet 15 through the air outlet 8 and is delivered to the designated area inside the vehicle along the corresponding air outlet 15, realizing on-demand air supply in the cooling state.

[0035] When heating is required, the evaporator stops heat exchange, and air at room temperature enters the air inlet 7 through the evaporator area and then enters the air inlet chamber 4. The heater 10 turns on and heats the airflow, which then enters the air outlet chamber 6. In the air outlet chamber 6, the regulating motor 11 continues to control the rotation of the air guide plate 13, so that the airflow enters the first air outlet zone 18 or the second air outlet zone 19 as needed, and is finally delivered to the corresponding area inside the vehicle through the air outlet duct 15 to complete the heating and air supply.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
