Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an automotive air conditioning temperature zone adjustment device. Background Technology

[0002] Automotive air conditioning systems use a compressor to compress refrigerant, which is then condensed and released by the condenser before being evaporated and absorbed by the evaporator. The processed air is then delivered to the passenger compartment by a blower, thus achieving cooling, heating, or ventilation functions. Its main function is to regulate the temperature and humidity inside the passenger compartment, filter impurities in the air, and create a comfortable in-vehicle environment for passengers. Simultaneously, by adjusting the direction and volume of the air vents, the air distribution in different areas of the vehicle can be optimized to meet basic micro-environmental needs for driving and riding. For example, patent application number CN202210952206.9 discloses an air conditioning system and a car. In this system, the first heat exchange duct houses a condenser, and its first air inlet includes a first air inlet connecting to the recirculated air inlet inside the vehicle and a second air inlet connecting to the outside of the vehicle. The first air outlet connects to a first air outlet inside the vehicle and a second air outlet connecting to the outside of the vehicle. The second heat exchange duct has a built-in evaporator, and its second air inlet includes a third air inlet connecting to the vehicle's internal recirculation air inlet and a fourth air inlet connecting to the outside of the vehicle. Its second air outlet connects to both the vehicle's internal third air outlet and the outside fourth air outlet. The first recirculation duct is used to recover the gas that has undergone heat exchange in the first heat exchange duct and transport it to the first air inlet and / or the third air inlet. The second recirculation duct is used to recover the gas that has undergone heat exchange in the second heat exchange duct and transport it to the first air inlet and / or the third air inlet. This invention improves the heating or cooling rate of the air conditioning system.

[0003] Existing automotive air conditioning systems adjust the temperature of each zone by controlling the airflow volume at the respective zone's air outlet, rather than by simultaneously and directly regulating the temperature at the air outlet. This temperature control method, which relies primarily on airflow adjustment, is difficult to accurately match the actual temperature requirements of different zones, resulting in poor temperature control precision. It is also difficult to provide a comfortable environment for passengers, lacks flexibility, and is not very practical. Utility Model Content

[0004] This utility model relates to a vehicle air conditioning temperature zone adjustment device, which has a zone component. The zone component dynamically proportions and mixes airflows of different temperatures on the front and rear sides of the vehicle's evaporator according to demand, and precisely controls the outlet temperature of the corresponding zone's air outlet, thereby realizing independent temperature adjustment function for each zone. Compared with the traditional method of indirectly adjusting the temperature by simply changing the airflow of the air outlet, this temperature control logic based on airflow proportion does not rely on increasing or decreasing the airflow to intervene in the temperature. It can avoid the discomfort of the driver and passengers caused by sudden changes in airflow, and can also make the temperature of each zone quickly approach the set value, which greatly improves the response speed and accuracy of zone temperature control. At the same time, this method can maintain a stable airflow in each zone at the target temperature, effectively solving the problem that it is difficult to balance "temperature control" and "airflow comfort" in traditional solutions, and further optimizing the personalized comfort experience of different drivers and passengers in the vehicle.

[0005] This utility model provides an automotive air conditioning temperature zone adjustment device, specifically including: an air intake seat and a zone component, wherein the zone component is composed of a flow divider seat and a temperature adjustment mechanism; The air intake seat is fixedly installed on the center console frame of the vehicle, and the air distribution seat is fixedly installed on the top of the air intake seat. The temperature control mechanism includes a distribution plate and an adjustment motor. The distribution plate is rotatably connected to the top of the air distribution seat and is also rotatably connected inside the air distribution seat. The rotating shaft of the adjustment motor and the distribution plate are connected by a bevel gear set.

[0006] Furthermore, the interior of the air duct is provided with an air conditioning duct and a natural air duct. One end of the air conditioning duct is connected to the air outlet duct behind the vehicle's evaporator, and one end of the natural air duct is connected to the air inlet duct in front of the vehicle's evaporator through a pipe.

[0007] Furthermore, the interior of the distribution seat is provided with a temperature air duct and a normal temperature air duct, with one end of the temperature air duct connected to the air conditioning air duct and the other end of the normal temperature air duct connected to the natural air duct.

[0008] Furthermore, the front ends of the temperature air duct and the normal temperature air duct are respectively provided with a temperature regulating air outlet and a mixing regulating air outlet, and the cross-section of the temperature regulating air outlet and the mixing regulating air outlet is an arc-shaped design.

[0009] Furthermore, the inside of the diverter plate is provided with arc-shaped adjustment holes.

[0010] Furthermore, the partitioning component is provided in four groups, and the number is not limited to four groups. The number can be increased or decreased, and the air outlet end of the air distribution seat of each partitioning component is connected to the air outlet inside the car.

[0011] This utility model provides a vehicle air conditioning temperature zone adjustment device, which has the following beneficial effects: The zoned airflow system dynamically proportions and mixes airflows at different temperatures on the front and rear sides of the vehicle's evaporator according to demand, precisely controlling the outlet temperature of each zone's vents. This enables independent temperature regulation for each zone. Compared to traditional methods that indirectly adjust temperature by simply changing the airflow volume at the vents, this temperature control logic based on airflow proportions eliminates the need to intervene in temperature by increasing or decreasing airflow. This avoids discomfort for passengers caused by sudden fluctuations in airflow and allows each zone's temperature to quickly approach the set value, significantly improving the response speed and accuracy of zoned temperature control. Simultaneously, this method ensures that each zone maintains a stable airflow at the target temperature, effectively solving the problem of balancing "temperature control" and "airflow comfort" in traditional solutions. This further optimizes the personalized comfort experience for different passengers in the vehicle, enhancing the flexibility and practicality of the device. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 6 Example 1: This utility model proposes an automotive air conditioning temperature zone adjustment device, including: an air intake seat 1 and a zone component, the zone component being composed of a flow divider seat 2 and a temperature adjustment mechanism 3; The air intake seat 1 is fixedly installed on the central control frame of the car, and the air diverter seat 2 is fixedly installed on the top of the air intake seat 1. The temperature control mechanism 3 includes a diverter plate 301 and an adjusting motor 302. The diverter plate 301 is rotatably connected to the top of the air diverter seat 2 and is rotatably connected inside the air diverter seat 2. The rotating shaft of the adjusting motor 302 and the diverter plate 301 are connected by a bevel gear set.

[0023] The regulating motor 302 is electrically connected to the control device of the automotive air conditioning system. Its specific structure and working principle are existing mature technologies and will not be described in detail here.

[0024] The air intake seat 1 contains an air conditioning duct 101 and a natural air duct 102. One end of the air conditioning duct 101 is connected to the air outlet duct behind the car's evaporator, and one end of the natural air duct 102 is connected to the air inlet duct in front of the car's evaporator via a duct. The air distribution seat 2 contains a temperature duct 201 and a normal temperature duct 202. One end of the temperature duct 201 is connected to the air conditioning duct 101, and one end of the normal temperature duct 202 is connected to the natural air duct 102. In use, the air conditioning duct 101 and the natural air duct 102 are connected to the ducts before and after the car's evaporator, respectively. Thus, the air conditioning duct 101 receives airflow cooled or heated by the air conditioning system, while the natural air duct 102 receives airflow from outside the car or... The ambient temperature airflow inside the vehicle, after being cooled or heated by the air conditioning system, can enter the interior of the temperature air duct 201, while the ambient temperature airflow will enter the ambient temperature air duct 202. By adjusting the exhaust ratio of the airflow inside the temperature air duct 201 and the ambient temperature air duct 202, the temperature control and regulation functions can be achieved. The airflow after temperature regulation can be directly discharged from the air outlet inside the car, thereby regulating the temperature inside the car. There are four groups of partition components, but the number is not limited to four and can be increased or decreased. The air outlet end of the splitter seat 2 of each partition component is connected to the air outlet inside the car. Different partition components can regulate the air outlet temperature at different air outlets inside the car, thereby achieving the function of partition control, which is convenient and flexible to use.

[0025] The front ends of the temperature duct 201 and the ambient temperature duct 202 are respectively provided with a temperature regulating vent 2011 and a mixing regulating vent 2021. The cross-sections of the temperature regulating vent 2011 and the mixing regulating vent 2021 are both arc-shaped. The inside of the diverter plate 301 is provided with an arc-shaped adjustment hole 3011. In use, the temperature regulating mechanism 3 can realize the function of proportional discharge of airflow inside the temperature duct 201 and the ambient temperature duct 202. When the regulating motor 302 rotates, the regulating motor 302 can drive the diverter plate 301 to rotate. When the diverter plate 301 rotates, the adjustment hole 3011 will overlap with the temperature regulating vent 2011 and the mixing regulating vent 2021. By controlling the overlapping area of ​​the adjustment hole 3011 with the temperature regulating vent 2011 and the mixing regulating vent 2021, the temperature regulation and control function can be realized, and the control is quick and convenient.

[0026] The working principle of this embodiment is as follows: After the vehicle air conditioner is turned on, the zone component can adjust the air outlet temperature of the corresponding zone according to the preset value. The air conditioning duct 101 and the natural air duct 102 are connected to the pipes before and after the car's air conditioning unit, respectively. Thus, airflow cooled or heated by the air conditioning system flows into the air conditioning duct 101, while ambient temperature airflow from outside or inside the car flows into the natural air duct 102. The airflow cooled or heated by the air conditioning system can then enter the temperature duct 201, while the ambient temperature airflow enters the ambient temperature duct 202. By adjusting the emission ratio of the airflow inside the temperature duct 201 and the ambient temperature duct 202, the function of temperature control and regulation can be achieved, directly controlling the airflow temperature. After temperature adjustment, the airflow is discharged from the car's interior air vents, thus regulating the temperature inside the car. At the same time, different zone components can regulate the air outlet temperature at different car interior air vents, thereby achieving zone control. The temperature adjustment mechanism 3 can achieve the function of proportional discharge of airflow inside the temperature duct 201 and the normal temperature duct 202. When the adjustment motor 302 rotates, it can drive the splitter plate 301 to rotate. When the splitter plate 301 rotates, the adjustment hole 3011 will overlap with the temperature adjustment air vent 2011 and the mixing air vent 2021. By controlling the overlapping area of ​​the adjustment hole 3011 with the temperature adjustment air vent 2011 and the mixing air vent 2021, the temperature adjustment and control functions can be achieved.
