Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted refrigeration equipment, specifically to air conditioning units and new energy vehicles. Background Technology

[0002] In a car, the air conditioning unit is a crucial component for cooling, heating, ventilation, and air purification inside the vehicle. It typically offers various modes, including face-blowing, face-to-feet-blowing, feet-blowing, feet-to-defrosting, defrosting, Bi-level, and Tri-level. From a comfort and safety perspective, there are corresponding design requirements for the air outlet temperature in different modes and the temperature difference between different air outlets. In Bi-level and Tri-level modes, the face-blowing air temperature is usually required to be lower than the feet-blowing air temperature. This temperature difference ensures comfort while keeping the driver alert and improving driving safety. The face-to-feet temperature difference is typically required to be between 5 and 10°C (different companies may have different requirements and designs).

[0003] Existing technology involves designing a fixed airflow guiding structure inside the air conditioning unit, behind the heat core, at the junction of cold and hot air (mixing zone). This structure directs some hot air to the front air outlet and some cold air to the foot air outlet, ensuring that the front and foot temperatures are close, with the front temperature slightly lower than the foot temperature. When the temperature damper moves within the range of full cooling to full heating, the temperature difference between the front and foot fluctuates within the design requirements under the influence of this airflow guiding structure. However, in existing airflow guiding structure designs, in Bi-level and Tri-level modes, the front-foot temperature difference is a fixed value when the temperature damper is at a certain position and cannot be actively adjusted; during the damper's movement, the front-foot temperature difference fluctuates within the design range, making the temperature difference uncontrollable.

[0004] Since different people perceive temperature differently, some drivers and passengers may require a greater temperature difference between their face and feet for comfort. A 5-10°C temperature difference between the face and feet is a standard summarized by the industry that applies to most people, and meeting the requirements of a smaller group can also enhance the product's competitiveness.

[0005] The same person's need for this temperature difference may vary depending on their state. When driving for a long time and feeling relatively tired, the driver will need cooler air blowing on their face to stay awake. If a higher temperature is also needed to maintain the overall temperature inside the car, simply adjusting the temperature vents to the colder direction and lowering all the air outlet temperatures is not advisable.

[0006] In view of this, the present invention provides an air conditioning unit and a new energy vehicle. Utility Model Content

[0007] In view of the problems in the prior art, the present invention provides an air conditioning unit that overcomes the difficulties of the prior art and can adjust the ratio of the heated airflow to the front blowing air duct and the front blowing foot air duct group to achieve the surface and foot temperature difference between the front blowing surface and the front blowing foot.

[0008] An embodiment of this utility model provides an air conditioning unit, comprising:

[0009] An air conditioning unit housing, wherein an evaporator core, a temperature damper, and a heating core are sequentially arranged inside the airflow direction;

[0010] A front air duct assembly and a rear air duct assembly are respectively located downstream of the heating core; and

[0011] A baffle assembly is disposed downstream of the heating core. The baffle assembly includes a rotating shaft and at least one three-dimensional air channel guide. The rotating shaft drives the three-dimensional air channel guide to rotate, changing the airflow ratio between the front blowing air channel and the front blowing foot air channel group after the heated airflow passes through the heating core and is guided by the three-dimensional air channel guide.

[0012] Preferably, the three-dimensional air duct guide has two three-dimensional intersecting guide surfaces. The guide surfaces guide part of the heated airflow to the front blowing foot air duct assembly. At least part of the heated airflow flows to the front blowing surface air duct after passing through the three-dimensional air duct guide. The three-dimensional structure formed by the guide surfaces changes the cross-sectional area that blocks the heated airflow from flowing to the front blowing surface air duct when the rotating shaft rotates.

[0013] Preferably, the front foot airway assembly includes a front left foot airway and a front right foot airway, the front left foot airway and the front right foot airway being located at opposite ends of the axial direction of the rotating shaft.

[0014] Preferably, the deflector assembly includes two three-dimensional air duct guides spaced apart from the rotation axis. Each three-dimensional air duct guide is a V-shaped guide with two guiding surfaces. The two guiding surfaces of the two V-shaped guides, which are positioned opposite each other, guide a portion of the heated airflow to the front left foot duct and the front right foot duct, respectively.

[0015] Preferably, the two adjacent guide surfaces of the two V-shaped air guides respectively guide a portion of the heated airflow to the rear airflow duct group, which includes a rear left airflow duct, a rear airflow duct and a rear right airflow duct arranged side by side.

[0016] Preferably, the hot airflow passing through the guide plate assembly between the three-dimensional air duct guides flows to the defrost air duct and the front blowing air duct.

[0017] Preferably, an angled air passage is formed between two adjacent guide surfaces of the V-shaped air guide, and part of the heated airflow flows through the angled air passage to the defrost air passage and the front blowing air passage.

[0018] Preferably, it further includes: an angle contraction mechanism is provided between the guide surfaces of the three-dimensional airway guide, the contraction mechanism changing the included angle between each guide surface to independently adjust the proportion of heated airflow to each airway.

[0019] Preferably, it further includes: an actuator motor disposed at the end of the rotating shaft, which drives the rotating shaft to rotate.

[0020] An embodiment of this utility model also provides a new energy vehicle, including the above-mentioned air conditioning unit, and further including:

[0021] The first temperature sensor is located at the air outlet of the front blowing air duct;

[0022] The second temperature sensor is located at the air outlet of the front foot air duct assembly. When the difference between the first detected temperature of the first temperature sensor and the second detected temperature of the second temperature sensor is less than a preset threshold, the rotating shaft is driven to rotate the three-dimensional air duct guide to reduce the portion of the heated airflow flowing to the front foot air duct.

[0023] The air conditioning unit and new energy vehicles of this utility model can adjust the ratio of the heated airflow to the front blowing air duct and the front blowing foot air duct group to achieve the surface and foot temperature difference between the front blowing surface and the front blowing foot.

Figure 5 This is a side view of the air deflector assembly of this utility model. Figure 6 This is a perspective view of the air deflector assembly of this utility model. Figures 1 to 6As shown, the air conditioning unit of this utility model includes: an air conditioning unit shell 1, a front air duct assembly, a rear air duct assembly, and a baffle assembly 2. The air conditioning unit shell 1 contains, sequentially along the airflow direction, an evaporator core 18, a temperature damper 10, and a heating core 19. The front and rear air duct assemblies are respectively located downstream of the heating core 19. The baffle assembly 2 is located downstream of the heating core 19 and includes a rotating shaft 21 and at least one three-dimensional air duct guide 22. The rotating shaft 21 drives the three-dimensional air duct guide 22 to rotate, changing the airflow ratio between the front face air duct 12 and the front foot air duct assembly after the heated airflow through the heating core 19 is guided by the three-dimensional air duct guide 22. When the face and foot temperature difference needs to be actively adjusted to adapt to the needs of different people and different driving conditions, the existing technology cannot achieve this. This invention provides a solution that allows for active adjustment of the temperature difference between the air outlet temperature for the face and the air outlet temperature for the feet in Bi-level and Tri-level modes.

[0062] In a preferred embodiment, the three-dimensional airway guide 22 is provided with two three-dimensional intersecting guide surfaces. The guide surfaces guide part of the heated airflow to the front foot airway assembly. At least part of the heated airflow flows to the front airway 12 after passing through the three-dimensional airway guide 22. The three-dimensional structure formed by the guide surfaces changes the cross-sectional area of ​​the airway 12 that blocks the heated airflow when it rotates with the rotating shaft 21, but this is not a limitation.

[0063] In a preferred embodiment, the front foot airway assembly includes a front left foot airway 13 and a front right foot airway 14, which are located at opposite ends of the axial direction of the rotation shaft 21, but are not limited thereto.

[0064] In a preferred embodiment, the deflector assembly 2 includes two three-dimensional air duct guides 22 spaced apart from the rotation axis 21. Each three-dimensional air duct guide 22 is a V-shaped guide with two guide surfaces. The two guide surfaces of the two V-shaped guides, which are positioned opposite to each other, guide a portion of the heated airflow to the front left foot duct 13 and the front right foot duct 14, respectively, but are not limited thereto.

[0065] In a preferred embodiment, the two adjacent guide surfaces of the two V-shaped guides respectively guide a portion of the heated airflow to the rear airflow duct group, which includes a rear left airflow duct 15, a rear airflow duct 16 and a rear right airflow duct 17 arranged side by side, but is not limited thereto.

[0066] In a preferred embodiment, the hot airflow passing through the baffle assembly 2 between the three-dimensional air duct guides 22 flows to the defrost air duct 11 and the front blowing air duct 12, but is not limited thereto.

[0067] In a preferred embodiment, an angled air passage is formed between two adjacent guide surfaces of the V-shaped air guide, through which part of the heated air flows to the defrost air passage 11 and the front blowing air passage 12, but this is not a limitation.

[0068] In a preferred embodiment, the system further includes an angle contraction mechanism between the guide surfaces of the three-dimensional airway guide 22. The contraction mechanism changes the included angle between each guide surface to independently adjust the proportion of heated airflow to each airway, but is not limited thereto.

[0069] In a preferred embodiment, it further includes: an actuator 23 disposed at the end of the rotating shaft 21, which drives the rotating shaft 21 to rotate, but is not limited thereto.

[0070] This utility model also provides a new energy vehicle, including the air conditioning unit as described above, and further including:

[0071] The first temperature sensor is located at the air outlet of the front air duct 12.

[0072] The second temperature sensor is located at the air outlet of the front footwell air duct assembly. When the difference between the first detected temperature of the first temperature sensor and the second detected temperature of the second temperature sensor is less than a preset threshold, the rotating shaft 21 is driven to rotate the three-dimensional air duct guide 22 to reduce the portion of heated airflow flowing towards the front footwell air duct 12, thereby adjusting the temperature difference between the interior surface temperature and the footwell temperature. Other related technical features and effects are as described above and will not be repeated here. This invention helps improve the overall NVH (noise, vibration, and harshness) of new energy vehicles; it is a comprehensive issue that measures the quality of automobile manufacturing, and its impact on the user's experience is the most direct and superficial.

[0073] The specific embodiments of this utility model are as follows:

[0074] refer to Figures 1 to 5The air conditioning unit of this invention is installed in a new energy vehicle. Inside the air conditioning unit housing 1, along the airflow direction, are sequentially arranged an evaporator core 18, a temperature damper 10, and a heating core 19. The front airflow duct assembly and the rear airflow duct assembly are respectively located downstream of the heating core 19. A guide vane assembly 2 is located downstream of the heating core 19. The guide vane assembly 2 includes a rotating shaft 21, at least one three-dimensional airflow guide component 22, and an actuator motor 23. The rotating shaft 21 drives the three-dimensional airflow guide component 22 to rotate, changing the airflow ratio between the front airflow duct 12 and the front foot airflow duct assembly after the heated airflow through the heating core 19 is guided by the three-dimensional airflow guide component 22. The actuator motor 23 is located at the end of the rotating shaft 21, driving the rotating shaft 21 to rotate. The three-dimensional airflow guide 22 has two intersecting guide surfaces. These guide surfaces direct a portion of the heated airflow to the front foot airflow duct assembly. At least a portion of the heated airflow flows to the front surface airflow duct 12 after passing through the three-dimensional airflow guide 22. The three-dimensional structure formed by the guide surfaces changes the cross-sectional area obstructing the flow of heated airflow to the front surface airflow duct 12 as the rotating shaft 21 rotates. The front foot airflow duct assembly includes a front left foot airflow duct 13 and a front right foot airflow duct 14, located at opposite ends of the axial direction of the rotating shaft 21. A first temperature sensor is positioned at the outlet of the front surface airflow duct 12, and a second temperature sensor is positioned at the outlet of the front foot airflow duct assembly. When the difference between the first detected temperature of the first temperature sensor and the second detected temperature of the second temperature sensor is less than a preset threshold, the rotating shaft 21 is driven to rotate the three-dimensional airflow guide 22 to reduce the portion of the heated airflow flowing to the front surface airflow duct 12. This invention proposes a rotatable flow guide structure assembly, consisting of a flow guide plate and an actuator motor. The flow guide plate has a rotating shaft, and the motor drives the flow guide plate to rotate around the rotating shaft. The motor and the rotating shaft can be directly driven by a spline connection, or indirectly driven by a connecting rod and crank structure. The shape of the flow guide plate is related to the shape of the internal flow field of the air conditioning unit, and can be a "V" shape as shown, or any other shape.

[0075] Continue to refer to Figure 6The deflector assembly 2 includes two three-dimensional air duct guides 22 spaced apart on the rotation axis 21. Each three-dimensional air duct guide 22 is a V-shaped guide with two guiding surfaces. The two guiding surfaces 221 and 224 of the two V-shaped guides, which are positioned opposite each other, guide a portion of the heated airflow horizontally to the front left foot air duct 13 (see airflow direction F1-F4) and the front right foot air duct 14 (see airflow direction F8-F0). The two adjacent guiding surfaces 222 and 223 of the two V-shaped guides guide a portion of the heated airflow to the rear air duct group (see flow direction F3-F5 and flow direction F6-F9). The rear air duct group includes the rear left air duct 15, the rear air duct 16, and the rear right air duct 17 arranged side by side. The hot airflow passing through the guide plate assembly 2 between the three-dimensional air duct guides 22 flows vertically upward to the defrost air duct 11 and the front blowing air duct 12. In this embodiment, an angled air duct is formed between two adjacent guide surfaces of the V-shaped guide, and part of the heated airflow flows through the angled air duct to the defrost air duct 11 and the front blowing air duct 12 (see airflow direction F2 and F7).

[0076] refer to Figures 1 to 3 As shown, this is a rotating airflow guide assembly suitable for single-temperature zone air conditioning units, which actively controls the temperature difference between the front airflow surface and the front airflow feet, regardless of whether it's the driver or passenger side. The airflow guide can be a single piece running through both the driver and passenger sides of the air conditioning unit, or it can be independent and connected by shafts and splines. This rotating airflow guide structure is designed with a rotation angle range (0°~α), where 0° is called the starting position and α is called the ending position. In Bi-level and Tri-level modes, the temperature difference between the front airflow surface and the front airflow feet is minimal when the airflow guide is at the starting position; the temperature difference is maximized when the airflow guide rotates to the ending position. During the rotation from the starting point to the ending point, the temperature difference between the front and the feet gradually increases, and the temperature of the feet is always higher than that of the front. By optimizing the shape of the airflow guide, it is also possible to ensure that the proportion of airflow from each air outlet remains almost unchanged or changes very little during rotation. In modes other than Bi-level and Tri-level, the flow guide is generally stationary and can be fixed at the starting position or at a specific angle.

[0077] Similarly, based on the above structure, it can be expanded to dual-zone, or even three-zone & four-zone, with independent deflectors and drive motors for each zone, to control the temperature difference between the driver's side, passenger side, left rear seat, and right rear seat. The rotatable deflector assembly consists of a deflector (with a rotating shaft), actuator, and connecting rod & crank (if required). When the deflector is at the starting position, the temperature difference between the driver's side and passenger side is minimal; when the deflector is at the ending position, the temperature difference is maximum. As the deflector rotates from the starting point to the ending point, the temperature difference between the driver's side and passenger side gradually increases, and the temperature blowing onto the feet is always greater than the temperature blowing onto the face. This allows for expansion from a single-zone air conditioning unit to a dual-zone or even three-zone & four-zone air conditioning unit, enabling individual control of the temperature difference between the driver's side, passenger side, left rear seat, and right rear seat according to requirements. Furthermore, in one variation, an angle contraction mechanism is provided between the guide surfaces of the three-dimensional air duct guide 22. The contraction mechanism changes the included angle between each guide surface to independently adjust the proportion of heated airflow to each air duct, thereby enabling independent adjustment of the temperature difference between the blowing surface and the foot for each seat in the front and rear rows.

[0078] This utility model can adjust the temperature difference between the front and rear of the vehicle according to the actual needs of the driver and passengers; it adds a "rotatable" attribute to the deflector plate based on the original air conditioning box structure, requiring only the addition of a corresponding number of actuators and connecting rods & cranks; during the rotation of the deflector plate, the proportion of air volume at each air outlet is almost unaffected, eliminating the need for recalibration and reducing the difficulty of development; it can be expanded from a single-temperature zone air conditioning box to a multi-temperature zone air conditioning box, and can be flexibly customized according to customer needs.

[0079] In summary, the air conditioning unit of this utility model can adjust the ratio of the heated airflow to the front blowing air duct and the front blowing foot air duct assembly, thereby achieving a temperature difference between the front blowing surface and the front blowing foot.

[0080] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
