[0002] The glove box is a storage compartment located in front of the passenger seat, used to store miscellaneous items. Typically, the glove box is relatively sealed off from the vehicle's air conditioning system, preventing the cool air from entering. This design can lead to excessively high temperatures inside the glove box during hot summer months, making it unsuitable for storing food, beverages, or easily melted or deformed items.

[0003] Therefore, those skilled in the art are dedicated to developing a new air conditioning device that can overcome the aforementioned deficiencies of the prior art. Utility Model Content

[0004] This disclosure provides an air conditioning device that, by providing a connecting channel on the housing of the air conditioning device that communicates with the hollow rotating shaft of the damper, can guide the cooling airflow in the duct to the outside of the air conditioning device, such as to the external casing, to cool the casing. This allows the casing to maintain a low temperature even in high summer temperatures. Furthermore, the above-mentioned arrangement allows the cooling airflow that has just reached the damper (i.e., the cooling airflow that has not yet undergone other heat exchange) to be directly guided to the external casing, improving the cooling efficiency of the casing and avoiding problems such as low integration and insufficient cooling efficiency caused by additional cooling holes in other locations on the housing. In addition, the connecting channel of this disclosure can selectively fluidly connect to the hollow rotating shaft of either of the two dampers. For example, connecting channels with their free ends blocked can be pre-set at the housing corresponding to the hollow rotating shafts of the two dampers, and one connecting channel can be opened at any time as needed, improving operational flexibility and avoiding a series of problems such as difficulty in manufacturing and inflexible placement caused by additional cooling holes on the housing.

[0039] The following specific embodiments illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification.

[0040] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this disclosure. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effectiveness and purpose of this disclosure, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "above" and "a" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this disclosure's implementation.

[0041] Vehicles typically have an air conditioning unit and a storage compartment (such as a glove box) inside. The air conditioning unit and the compartment are relatively sealed, preventing the cold air blown out by the air conditioning unit from entering the compartment. As a result, the temperature inside the compartment is high during the summer, making it unsuitable for storing food, beverages, or items that are prone to melting or deformation.

[0042] To address the aforementioned problems, this disclosure provides a novel air conditioning device that conveniently guides cooling airflow within the air conditioning unit into the housing. Specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0043] Please see Figures 2 to 4 The air conditioning unit 1 includes a housing 10 and a damper 20. The housing 10 has an air duct 100 that allows airflow and a connecting channel 11 that connects the interior of the housing 10 (especially the air duct 100) to the outside. The damper 20 has a rotating shaft 21, which is a hollow rotating shaft to reduce the weight of the damper 20 and allow airflow. The damper 20 is disposed in the air duct 100 of the housing 10 and can rotate relative to the housing 10 to realize the opening and closing of the damper 20 and control the airflow from the air inlet 30 of the housing 10 (e.g., Figure 8 (As shown) the direction or distribution of airflow entering the housing 10. The hollow rotating shaft (i.e., rotating shaft 21) of the damper 20 is connected to / communicates with the communication channel 11 of the housing 10, so that the air duct 100 is in fluid communication with the outside of the housing 10. This arrangement guides the cooling gas inside the air conditioning unit 1 to the outside, especially to the casing 3 outside the air conditioning unit 1 (such as...). Figure 1 As shown, the housing 3 is cooled by providing a connecting channel 11 on the housing 10 that is connected to the rotating shaft 21 of the damper 20 and guides the cooling airflow in the air duct 100 to the outside (e.g., to the housing 3 outside the housing 10). This allows the cooling airflow that has just flowed to the damper 20 (i.e., the cooling airflow that has not yet undergone other heat exchange) to be directly guided to the housing 3, thereby improving the cooling efficiency of the housing 3. At the same time, it avoids the problems of low integration and insufficient cooling efficiency caused by additional cooling holes in other positions of the housing 10.

[0044] Specifically, such as Figure 2 , Figure 7 and Figure 8 As shown, the housing 10 can define multiple different air ducts, each with a corresponding air outlet. For example, the front air duct has a front air outlet 31, which can be located above the housing 10 and is mainly used to provide airflow to the face or upper body of the front passenger; the rear air duct has a rear air outlet 32, which can be located in the center of the lower part of the housing 10 and is mainly used to provide airflow to the face or upper body of the rear passengers; the defrost air duct has a defrost outlet 33, which can also be located above the housing 10 and is mainly used to provide airflow to the windshield and side windows; the foot air duct has a foot outlet 34, which is located below the housing 10 and can be positioned on both sides of the rear air outlet 32 ​​and is mainly used to provide airflow to the feet of the passengers in the vehicle. The housing 10 also defines an air inlet 30 (e.g., Figure 8 As shown), the air inlet 30 can be located on the side of the housing 10. The airflow can enter the main air duct (such as the air duct 100 mentioned above) inside the housing 10 from the air inlet 30, and the direction or distribution of the airflow can be controlled by the cooperation of multiple air dampers 20 and other mixing air dampers (not shown). For example, part of the airflow can enter the front blowing air duct, the rear blowing air duct, the defrosting air duct and / or the foot blowing air duct.

[0045] The air conditioning unit 1 may also include an evaporator (not shown), which is disposed at the air inlet 30 of the housing 10 and fits tightly around the periphery of the air inlet 30 to avoid air leakage and problems such as low heat exchange efficiency. The refrigerant in the evaporator can exchange heat with the airflow outside the evaporator to achieve the effect of cooling the airflow. Specifically, the refrigerant in the evaporator absorbs heat and converts the refrigerant into a gaseous state, while the airflow outside the evaporator releases heat, thus cooling the airflow. The airflow cooled by the evaporator can then flow into the housing 10 through the air inlet 30, especially into the air duct 100 of the housing 10. The damper 20 is disposed in the air duct 100 near the air inlet 30, so that the airflow cooled by the evaporator flows to the damper 20 almost without undergoing other heat exchange, and then is guided to the casing 3 outside the housing 10 through the connecting channel 11, which can effectively improve the cooling efficiency of the casing 3.

[0046] Please refer to the above. Figures 4 to 8 as well as Figures 12 to 13 The connecting channel 11 is disposed on the housing 10 near the air inlet 30 and connected to the hollow rotating shaft of the damper 20 to guide the cooling airflow within the air duct 100, especially at the damper 20, to the outside of the housing 10. In one embodiment, the connecting channel 11 can be integrally formed with the housing 10 to avoid wasted time and misalignment caused by additional installation. The connecting channel 11 can be generally tubular; in one embodiment, the connecting channel 11 can be a circular tubular channel to facilitate manufacturing (or demolding of the housing 10) and to facilitate connection with external components (e.g., Figure 1 The connecting pipe 2) shown is used for a sealed connection. Specifically, the connecting channel 11 can be configured to extend along the same axis as the hollow rotation axis of the damper 20. That is, the connecting channel 11 can be configured as a straight channel extending along the rotation axis of the damper 20, so as to simplify its structure and facilitate its manufacture. Of course, this disclosure is not limited to the above-described structure of the connecting channel 11, as long as the airflow of the duct 100 is guided to the outside of the housing 10.

[0047] Please continue reading Figure 5 , Figure 12 and Figure 13 The connecting channel 11 includes an inner portion 110 disposed inside the housing 10 and an outer portion 111 disposed outside the housing 10. The inner portion 110 is primarily used for connecting / connecting the hollow rotating shaft (i.e., rotating shaft 21) of the damper 20. In one embodiment, the inner portion 110 may be a tubular channel with a smooth outer wall, facilitating partial insertion into the hollow rotating shaft of the damper 20 and simplifying the installation of the connecting channel 11 and the damper 20. The outer portion 111 is primarily used for connecting, for example, a connecting pipe 2 (such as...). Figure 1The external component (as shown). In one embodiment, a radially outwardly projecting flange 13 may be provided at the free end of the external portion 111 (i.e., the end away from the internal portion 110). Figure 9 As shown), so as to facilitate snap-fitting, for example, connecting tube 2 (as shown). Figure 1 The external component (shown) forms a radial seal with the connecting pipe 2 to prevent fluid leakage. In one embodiment, the flange 13 may be annular and surround the entire circumference of the external portion 111. However, this disclosure is not limited to this; for example, the flange 13 may also be fan-shaped and surround a portion of the circumference of the external portion 111, as long as the flange 13 facilitates the connection and sealing between the communication channel 11 and the external component (e.g., the connecting pipe 2).

[0048] Please see Figure 3 and Figure 6 The housing 10 has at least two supports (e.g., on the outer wall of the housing 10) provided inside. Figure 3 and Figure 7 The dampers 20 on the left and right walls of the housing 10 shown (this disclosure uses two as examples, but is not limited to this). The two dampers 20 have roughly the same structure, only differing slightly in the structure at their connection (described later), and the rest of the structure can be mirrored. The following mainly describes one damper 20 (for example...). Figure 6 The specific structure of the damper 20 on the left side is shown.

[0049] Please see Figure 10 and Figure 11 The damper 20 may be generally drum-shaped. Specifically, the damper 20 may include a rotating shaft 21 and a body portion 22 connected to the rotating shaft 21. The body portion 22 has two side walls 221 and 222 arranged in a generally parallel manner, and a peripheral wall 223 connected between the side walls 221 and 222. The side walls 221 and 222 are used to connect the peripheral wall 223 to the rotating shaft 21, so that when the rotating shaft 21 rotates, it drives the peripheral wall 23 to rotate, thereby opening and closing the damper 20 and controlling the direction of airflow. Of course, this disclosure is not limited to the above-described structure of the damper 20. For example, the damper 20 may also be disc-shaped or other suitable shapes, as long as it can open and close to control the direction of airflow.

[0050] Please continue reading Figure 10 and Figure 11The first end of the damper 20 (i.e., the end near the side wall 221, or the end near the outside of the housing 10) has a hollow rotating shaft 21 for insertion into the connecting channel 11. Airflow in the duct 100 can flow through the hollow portion of this hollow rotating shaft to the connecting channel 11, and then to the outside of the housing 10. The second end of the damper 20 (i.e., the end near the side wall 222) may also have a hollow rotating shaft for insertion into another damper 20. In this embodiment, the second end of the damper 20 (i.e., the end near the side wall 222) may be a connecting shaft with a radial dimension smaller than the aforementioned hollow rotating shaft. It is mainly used for inserting / connecting the rotating shaft of another damper 20 and supporting the other damper 20, such as... Figure 6 As shown.

[0051] In one embodiment, the first end of the damper 20 is further provided with a gear 23 fixedly connected to the rotating shaft 21, the gear 23 being coaxially arranged with the rotating shaft 21. The gear 23 passes through the central hole of the rotating shaft 21, allowing the airflow in the air duct 100 to flow into the connecting channel 11. Alternatively, the rotating shaft 21 of the damper 20 may include a gear 23 coaxially arranged at one end near the outside of the housing 10, with the gear 23 passing through the central hole of the rotating shaft 21. A drive mechanism (not shown) drives the damper 20 to rotate by driving the gear 23.

[0052] The rotating shaft 21 of the damper 20, especially its gear 23, is configured to surround the inner portion 10 of the communicating channel 11 of the housing 10, or in other words, the inner portion 10 of the communicating channel 11 can be inserted into the hollow rotating shaft, especially into the gear 23 (e.g. Figure 5 As shown), this allows the connecting channel 11 to be connected to the hollow rotating shaft of the damper 20, so that the airflow in the duct 100 flows to the outside of the housing 10 via the hollow rotating shaft and the connecting channel 11.

[0053] In order for the drive mechanism (not shown) outside the housing 10 to drive the connecting gear 23, such as Figure 11 and 12 As shown, a connection port 35 may be provided at the connection between the connecting channel 11 and the housing 10. This connection port 35 may be a fan-shaped annular opening. When the gear 23 is inserted into the connecting channel 11, the gear 23 can be exposed to the outside of the housing 10 via the connection port 35 (e.g., ...). Figure 5 As shown), so that the drive mechanism outside the housing 10 can drive the gear 23 connected to it, thereby driving the damper 20 to rotate.

[0054] Please return to the previous page. Figure 6 The connecting channel 11 can selectively fluidly connect the hollow rotating shaft of either of the two dampers 20. This disclosure mainly uses the connecting channel 11 to connect... Figure 6The hollow rotating shaft of the damper 20 shown on the left is used as an example for illustration, but it is not limited to this. Designers can set it according to the relative position of the air conditioning unit 1 and the object to be cooled (e.g., the casing 3) and the actual situation. For example, it can be... Figure 6 The hollow rotating shafts of the two dampers 20 shown are respectively provided with pre-set connecting channels with their free ends blocked at the corresponding housing 10. When the air conditioning unit 1 needs to deliver cooling airflow to the outside through either of the connecting channels, the operator can open the connecting channel at any time to improve the degree of freedom of operation and avoid a series of problems such as difficulty in processing and inflexible setting caused by additional cooling holes on the housing 10.

[0055] As can be seen, the air conditioning device 1 described in this disclosure has a connecting channel 11 on the housing 10 that connects its interior and exterior. This connecting channel 11 can be connected to the hollow rotating shaft of the ventilation door 20. This arrangement allows the cooling airflow in the air duct 100 to flow to the exterior of the air conditioning device 1 via the hollow rotating shaft and the connecting channel 11, and to cool the external object (e.g., the housing 3). Thus, even in the high temperatures of summer, the interior of the housing 3 can be kept at a low temperature. Furthermore, the above-mentioned arrangement of this disclosure also allows the cooling airflow that has just reached the ventilation door 20 (i.e., the cooling airflow that has not yet undergone other heat exchange) to be directly guided to the housing 3, improving the cooling efficiency of the housing 3 and avoiding problems such as low integration and insufficient cooling efficiency caused by additional cooling holes in other locations of the housing. Furthermore, the connecting channel 11 disclosed herein can selectively fluidly connect the hollow rotating shaft of either of the two dampers 20. For example, connecting channels 11 with their free ends blocked can be pre-set at the housing 10 corresponding to the hollow rotating shafts of the two dampers 20, and a connecting channel 11 can be opened at any time according to actual needs to improve the degree of operational freedom and avoid a series of problems such as difficulty in processing and inflexible setting caused by additional cooling holes on the housing.

[0056] This disclosure also provides a cooling system 4. The following is in conjunction with... Figure 1 The specific implementation of the cooling system 4 will be described in detail below.

[0057] Please see Figure 1 The cooling system 4 includes the air conditioning unit 1, the housing 3, and the connecting pipe 2 that connects the air conditioning unit 1 and the housing 3 as described above. This arrangement can guide the cooling airflow in the air conditioning unit 1 into the housing 3 for cooling.

[0058] Specifically, the air conditioning unit 1 has a connecting channel 11 on the housing 10 near the box 3. The connecting channel 11 connects the air conditioning unit 1, especially its housing 10 or its air duct 100, to the inside and outside. The connecting channel 11 can connect to the hollow rotating shaft of the damper 20 in the air duct 100 and communicate with it in fluid, so that the cooling airflow in the air duct 100 can flow to the outside of the air conditioning unit 1 via the hollow rotating shaft and the connecting channel 11.

[0059] The housing 3 may be a vehicle glove box, but this disclosure is not limited to this; for example, the housing 3 may be any other component that requires internal cooling. The housing 3 is provided with a through hole for receiving cooling airflow from the air conditioning unit 1.

[0060] One end of the connecting pipe 2 is connected to and communicates with the communicating channel 11 of the air conditioning unit 1, and is particularly sealed to the flange 13 at the free end of the communicating channel 1 to prevent leakage of cooling airflow; the other end of the connecting pipe 2 is connected to and communicates with the through hole of the housing 3 to guide the cooling airflow in the air conditioning unit 1 into the interior of the housing 3, thereby cooling the housing 3. In this way, even in the high temperatures of summer, the housing 3 can hold food, beverages, and easily melted or deformed objects, keeping them at a low temperature and extending their storage time.

[0061] In one embodiment, the connecting pipe 2 can be a rigid connecting pipe to avoid the risk of excessive deformation leading to poor gas flow or easy rupture. Both ends of the connecting pipe 2 can be provided with rubber structures to facilitate a sealed connection with the connecting channel 1 and the housing 3, preventing fluid leakage.

[0062] This disclosure also provides a motor vehicle that may include the aforementioned cooling system 4.

[0063] Although the above embodiments of this disclosure are mainly described with the example of a straight tubular channel 11, this disclosure is not limited to this. For example, the connecting channel 11 can also be a curved tubular channel, as long as it can connect to the hollow rotating shaft of the ventilation door 20 and guide the airflow in the air duct 100 to the outside of the housing 10.

[0064] Furthermore, the above embodiments of this disclosure are mainly described with the example of the gear 23 of the damper 20 being exposed outside the housing 10. However, this disclosure is not limited to this. For example, the gear of the damper 20 may not be exposed outside the housing 10. In this case, a drive mechanism can be provided inside the housing 10 to drive the rotation of the damper 20, as long as the drive mechanism does not interfere with other components inside the housing 10.

[0065] The foregoing description, with reference to preferred embodiments, illustrates exemplary implementations of the air conditioning apparatus, cooling system, and motor vehicle provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
