Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning technology, specifically to an air conditioning box assembly, a vehicle body assembly, and a vehicle. Background Technology

[0002] With the development of the automotive industry, users are increasingly demanding higher costs and greater ease of maintenance for their vehicles. Existing commercial vehicle air conditioning systems employ a distributed filter design, which suffers from issues such as dispersed structure, inconvenient disassembly and maintenance, and high costs. While passenger vehicles generally use integrated filter structures, significant differences in passenger compartment layout and body-in-white structure between passenger vehicles and commercial vehicles mean that even with an integrated filter design, overall disassembly remains difficult, making it impossible to directly apply passenger vehicle filter solutions to commercial vehicles. Therefore, it is necessary to develop a completely new integrated air conditioning unit filter specifically for the characteristics of commercial vehicles. This design should improve disassembly convenience and reduce maintenance costs while ensuring filtration performance. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air conditioning unit assembly suitable for commercial vehicles, providing an integrated segmented filter element for both internal and external circulation on the air conditioning unit assembly.

[0006] According to the embodiment of this utility model, the air conditioning unit assembly connects both the internal and external air inlets to the filter chamber, ensuring that the internal and external circulation channels of the air conditioning unit assembly intersect at least at the filter chamber. The internal and external circulation channels share a common filter element, which is installed in one location within the housing, eliminating the need for another installation and fixing structure. This integrated filter element design reduces the overall space occupied by the air conditioning unit assembly. Furthermore, with only one disassembly point, disassembly and assembly are relatively simple. All sub-filter elements can be disassembled and installed sequentially from the mounting port, eliminating the need for complete filter element disassembly and assembly, reducing operational difficulty and the space required around the mounting port.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] In the description of this utility model, it should be understood that the terms "lateral," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this 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, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is for reference. Figures 1-6 The air conditioning unit assembly 10 according to an embodiment of the present utility model is described.

[0023] According to the air conditioning unit assembly 10 of this utility model embodiment, refer to Figures 1-2 It includes a housing 1 and a filter element 2.

[0024] like Figure 1 , 3 As shown, the housing 1 is provided with a filter chamber 11, and the housing 1 is also provided with an internal circulation air inlet 13 and an external circulation air inlet 14 that are connected to the filter chamber 11. The filter element 2 is located in the filter chamber 11.

[0025] In other words, the air conditioning unit assembly 10 of this application has an internal circulation channel and an external circulation channel inside the housing 1.

[0026] The air inlet of the internal circulation channel is the internal circulation air inlet 13, which connects to the passenger space of the vehicle. For example, the internal circulation air inlet 13 connects to the driver's cab to draw air in from the driver's cab. The air outlets of the internal circulation channel connect to the passenger space of the vehicle, for example, there are multiple air outlets that connect to the face vents, foot vents, defrost vents, etc. The internal circulation channel allows for internal air circulation inside the vehicle, preventing external odors and dust from entering the vehicle. Optionally, a heat exchanger is installed in the internal circulation channel to achieve temperature regulation.

[0027] The air inlet of the external circulation channel is the external circulation air inlet 14, which connects to the outside of the vehicle. For example, the external circulation air inlet 14 is connected to the air inlet below the windshield (usually equipped with a filter) via a connecting pipe. The air outlets of the external circulation channel connect to the passenger space of the vehicle. For example, there are multiple air outlets of the external circulation channel, which are respectively connected to the face vent, foot vent, defrost vent, etc. The external circulation channel keeps the air inside the vehicle fresh. Optionally, a heat exchanger is installed outside the external circulation channel to achieve temperature regulation.

[0028] In this application, both the internal circulation air inlet 13 and the external circulation air inlet 14 are connected to the filter chamber 11, meaning that the internal circulation channel and the external circulation channel intersect at least at the filter chamber 11. Furthermore, the internal circulation channel's path from the filter chamber 11 to its outlet, and the external circulation channel's path from the filter chamber 11 to its outlet, are identical. This significantly reduces the overall space occupied and cost of the air conditioning unit assembly 10.

[0029] Filter element 2 primarily functions to filter air. It can block solid particles such as dust, pollen, smoke, and PM2.5, as well as some bacteria and odors, ensuring that the air entering the vehicle is clean and healthy. At the same time, it protects other internal components of the air conditioning unit 10 from impurities, extends the service life of the air conditioning system, and improves the air quality and ride comfort inside the vehicle.

[0030] The housing 1 has an installation port 12 that connects to the filter chamber 11, and the filter element 2 is detachably installed in the filter chamber 11 through the installation port 12. In this way, the filter element 2 can be directly installed or removed through the installation port 12, which greatly simplifies the maintenance process of the filter element 2.

[0031] It should be noted that conventional commercial vehicles have filters installed in both the internal and external air circulation channels. Each filter needs to be installed and secured within its own housing, taking up considerable space and resulting in an overly large air conditioning unit that encroaches on legroom in the driver's cab. Furthermore, the two filter installation / removal points are inconvenient in the relatively cramped vehicle interior, leading to higher maintenance costs in the long run.

[0032] This application's solution uses a shared filter element 2 for both the internal and external circulation channels. The filter element 2 is installed in one location within the housing 1, eliminating the need for another installation and fixing structure. This integrated filter element design reduces the overall space occupied by the air conditioning unit assembly 10. Moreover, there is only one disassembly point, making disassembly and assembly relatively simple.

[0033] To further facilitate the maintainability of filter element 2, filter element 2 is configured as at least two sub-cores 21 in this application, so that all sub-cores 21 can be disassembled and installed in sections from the mounting port 12.

[0034] Understandably, the layout of devices inside a vehicle is very compact. For example, electrical and control devices, cooling and heat dissipation devices, etc., can be arranged next to the air conditioning assembly 10, resulting in a cluttered wiring harness and piping. When the air conditioning filter is removed and installed as a whole, the air conditioning assembly needs to have enough space outside the installation port to accommodate the entire filter. However, such a large amount of space affects the compact layout of the devices.

[0035] After the filter element 2 is divided into multiple sub-elements 21, the weight and volume of each sub-element 21 are significantly reduced. Users or maintenance personnel can directly disassemble the sub-elements 21 one by one through the installation port 12, without having to move the entire filter element 2, thus reducing the difficulty of operation. At the same time, when disassembling the sub-elements 21, the external space required for the installation port 12 is reduced. Even in relatively narrow areas inside the car where the air conditioning assembly 10 is installed, users or maintenance personnel can remove the sub-elements 21 with small operations, further improving the flexibility and adaptability of disassembly. This fundamentally solves the problems of inconvenient disassembly and low maintenance efficiency of the existing integral filter element 2. In addition, when maintenance personnel inspect the filter element 2, each sub-element 21 can be replaced individually, without having to replace the entire filter element 2, thus saving users replacement costs.

[0036] In some specific embodiments, reference is made to Figure 2 , Figure 4 The mounting port 12 is elongated, and at least two sub-cores 21 are sequentially spliced ​​along the length of the mounting port 12. This design results in a relatively long mounting port 12, which facilitates external observation of the installation status of the sub-cores 21 and helps ensure the accuracy of replacement.

[0037] Specifically with Figure 1 and Figure 2 Taking the orientation shown as an example, a mounting port 12 is provided on the rear side of the housing 1. Figure 1 and Figure 2 (Not shown), the mounting port 12 extends in the left-right direction. Two sub-cores 21 are installed inside the filter chamber 11. When disassembling, the left sub-core 21 can be pulled backward out of the mounting port 12 first, then the right sub-core 21 can be moved to the left and pulled backward out of the mounting port 12. In this way, the disassembly and assembly of the sub-cores 21 are not restricted by the right-side structure.

[0038] The disassembly of filter element 2 is simple and smooth, saving users or maintenance personnel time in maintaining filter element 2.

[0039] Specifically, the sub-core 21 is generally rectangular plate-shaped, and multiple sub-cores 21, when spliced ​​together along the length of the mounting opening 12, still maintain a rectangular plate shape. Optionally, the mounting opening 12 is rectangular.

[0040] Of course, the shapes of the filter element 21 and the mounting port 12 in this application are not limited to these. The position of the mounting port 12 and the method of assembling and disassembling the filter element 2 on the mounting port 12 are also not limited to these.

[0041] In some other embodiments, the filter element 2 is configured to include at least two sub-cores 21 distributed axially along the mounting port 12, such that all sub-cores 21 can be disassembled and installed in sections from the mounting port 12.

[0042] After the filter element 2 is divided into multiple sub-elements 21, the weight and volume of each sub-element 21 are significantly reduced. Users or maintenance personnel can directly disassemble the sub-elements 21 one by one through the installation port 12, eliminating the need to transport the entire filter element 2, thus reducing the difficulty of operation. At the same time, the space required around the installation port 12 is reduced when disassembling the sub-elements 21. Even in relatively narrow areas inside the car where the air conditioning assembly 10 is installed, users or maintenance personnel can remove the sub-elements 21 with small movements, further improving the flexibility and adaptability of disassembly. This fundamentally solves the problems of inconvenient disassembly and low maintenance efficiency of existing integral filter elements. In addition, when maintenance personnel inspect the filter element 2, each sub-element 21 can be replaced individually, without having to replace the entire filter element 2, saving users replacement costs.

[0043] like Figure 6 As shown, filter element 2 is a cylindrical body, with one end of the cylindrical body connected to connection port 161, so that airflow enters radially and flows axially to fan 151.

[0044] The cylindrical filter element 2 has a ring-shaped three-dimensional structure. It is hollow inside and forms a continuous filtration channel. Air first enters the filter medium inside the filter element 2 evenly from the ring end face around the cylinder. After being intercepted by the filter element 2 layer by layer, the air flows axially along the hollow part of the filter element 2 to the fan 151.

[0045] During the process of air entering filter element 2, the air is introduced from all sides of filter element 2, and the air flow path is reduced. Compared with traditional flat plate filter elements, the cylindrical filter element 2 has a significantly increased filtration area, which can hold more filter material in a small space and improve the efficiency of air filtration.

[0046] Optionally, such as Figure 6 As shown, each sub-core 21 has a first insertion part 212 at one end and a second insertion part 213 at the other end. The first insertion part 212 of one sub-core 21 of two adjacent sub-cores 21 is inserted and engaged with the second insertion part 213 of the other sub-core 21.

[0047] When two adjacent sub-cores 21 are joined, the operator first inserts the sub-cores 21 sequentially into the filter chamber 11 along the axial direction. The first insertion part 212 of one sub-core 21 precisely aligns with the second insertion part 213 of another sub-core 21 to achieve a fitting. Through the fitting of the insertion parts, multiple sub-cores 21 are tightly connected along the axial direction to form a filter element 2. The fitting of the first insertion part 212 and the second insertion part 213 ensures precise positioning and stable connection between two adjacent sub-cores 21, preventing individual sub-cores 21 from shifting and maintaining the integrity of the entire filter element 2 structure. Secondly, the fitting between the sub-cores 21 simplifies the assembly process of multiple sub-cores 21, ensuring a tight connection between multiple sub-cores 21 without the need for additional fixing structures. When the filter element 2 needs to be replaced or cleaned later, the operator can sequentially separate the inserted sub-cores 21 along the axial direction, reducing the difficulty of disassembling the sub-cores 21, reducing the space required for disassembling the filter element 2, and reducing the cost of replacing the entire filter element 2.

[0048] In some embodiments, refer to Figure 1 The housing 1 includes a blower box 15 and an air inlet shroud 16.

[0049] like Figure 1 , 3 As shown, a fan 151 is installed inside the blower box 15, and an air inlet hood 16 is connected to one side of the blower box 15. A filter chamber 11 is installed inside the air inlet hood 16. The air inlet hood 16 is connected to the blower box 15 through a connection port. The air inlet hood 16 is provided with an internal circulation air inlet 13 and an external circulation air inlet 14. The mounting port 12 is located on the air inlet hood 16. In this way, the filter element 2 is installed inside the air inlet hood 16 instead of inside the blower box 15. The installation position of the filter element 2 is not easily interfered with by the fan 151, etc., and it is easy to find a suitable position to place the mounting port 12.

[0050] When the air conditioning system is started, the fan 151 turns on to generate airflow. Depending on the circulation mode selection, the air inside and outside the passenger space enters the filter chamber 11 inside the air inlet hood 16 through the internal circulation air inlet 13 or the external circulation air inlet 14 set on the air inlet hood 16. Whether it is internal circulation or external circulation air, the air is filtered by the filter element 2 in the filter chamber 11 to remove impurities such as dust, pollen, and particles, thus completing the purification.

[0051] Subsequently, the filtered air enters the blower box 15 through the connection port 161 between the air inlet hood 16 and the blower box 15. Driven by the fan 151, the air is blown into subsequent components and precisely distributed to each air outlet in the passenger space. In addition, the air inlet hood 16 is connected laterally to the blower box 15, reducing the layout space of the air inlet hood 16 and the blower box 15, shortening the airflow path in the blower box 15, and reducing airflow resistance and energy loss. At the same time, the air intake and filtration functions are integrated into the air inlet hood 16, and the air distribution and air drive functions are integrated into the blower box 15, realizing a clear division of labor and efficient collaboration of functional modules.

[0052] Furthermore, the mounting port 12 is located on the side of the air inlet shroud 16 away from the blower box 15. On the one hand, when removing the filter element 2, it can be directly removed from the mounting port 12 without interfering with surrounding components such as the blower box 15, providing more operating space and greater convenience. At the same time, it eliminates the need to enter the interior of other components, reducing the risk of collision with other components during maintenance. On the other hand, air entering from the air inlet shroud 16 can be filtered first in the filter chamber 11 before flowing to the blower box 15. The mounting port 12 is far from the core airflow channel, reducing interference with the airflow path when removing the filter element 2 and ensuring smooth airflow from the air inlet shroud 16 to the blower box 15.

[0053] In some embodiments, refer to Figure 3 The air inlet shroud 16 is provided with an air inlet chamber 17 and a buffer chamber 18. The internal circulation air inlet 13 and the external circulation air inlet 14 are connected to the air inlet chamber 17. One end of the buffer chamber 18 is a connection port 161. The filter element 2 is plate-shaped and located between the air inlet chamber 17 and the buffer chamber 18.

[0054] Specifically, the air inlet cavity 17 includes an internal circulation air inlet 13 and an external circulation air inlet 14. When the internal circulation is turned on, air enters the air inlet cavity 17 from the internal circulation air inlet 13; when the external circulation is turned on, air enters the air inlet cavity 17 from the external circulation air inlet 14.

[0055] The fan 151 drives air into the air inlet chamber 17. The air driven by the fan 151 is usually at a high speed. The flat filter element 2 has a high overall structural strength and can withstand high-speed airflow while maintaining its shape stability. The high-speed air passes through the filter element 2 and enters the buffer chamber 18. At this time, the buffer chamber 18 provides a "buffer zone" for the high-speed air. The airflow enters the chamber, and the space inside the chamber is relatively open. The airflow speed decreases, and there is enough time and space to adjust the flow direction, so that the originally concentrated and high-speed airflow gradually disperses and becomes uniform. The airflow speed also tends to stabilize when it reaches the subsequent components, so as not to impact the subsequent components and reduce the probability of component damage.

[0056] In some embodiments, such as Figure 3 As shown, the air conditioning unit assembly 10 also includes an air intake adjustment component 3, which is rotatably disposed inside the air intake cover 16. The air intake adjustment component 3 has a first position with the external circulation air intake 14 closed and a second position with the internal circulation air intake 13 closed. The air intake adjustment component 3 can be switched between the first position and the second position to adjust the ratio of internal and external air intake.

[0057] The air intake regulating component 3 is the core component for precisely controlling airflow. Specifically, when the air intake regulating component 3 is in the first position with the external circulation air intake 14 closed, air enters the air intake cavity 17 from the internal circulation air intake 13; when the air intake regulating component 3 is in the second position with the internal circulation air intake 13 closed, air enters the air intake cavity 17 from the external circulation air intake 14. The air intake regulating component 3 dynamically distributes the airflow direction and volume by flexibly adjusting the opening and closing state and angle of each air intake damper: on the one hand, the air intake regulating component 3 can precisely control the airflow direction according to the driving needs, and directionally deliver filtered and temperature-controlled air to different areas of the vehicle (such as the face, feet, windshield, etc.). For example, in winter, warm air can be preferentially directed to the feet to enhance the feeling of warmth, while in summer, it can be concentrated on the face to enhance the cooling experience. On the other hand, the air intake adjustment component 3 coordinates the air volume distribution of each air intake to meet the personalized needs of different seating areas. Regardless of whether the air intake adjustment component 3 is located in the first or second position, it can introduce more fresh air, optimize the uniformity of the overall temperature field and air quality inside the vehicle, and ultimately achieve a highly efficient, comfortable and energy-saving air conditioning effect.

[0058] Furthermore, such as Figure 5 As shown, the air inlet shroud 16 is provided with a first support platform 162 and a second support platform 163 to support the filter element 2. The second support platform 163 is located at the mounting port 12, and the first support platform 162 and the second support platform 163 are arranged opposite to each other.

[0059] One side of the filter element 2 rests against the second support sleeve 163 at the mounting port 12, and the other side rests against the first support platform 162. The first support platform 162 and the second support platform 163 form a symmetrical and stable support structure for the filter element 2. The two support platforms 162 and 163 can not only effectively distribute the weight of the filter element 2 and the pressure generated by the airflow through the filter element 2, but also prevent the filter element 2 from deforming or shifting due to uneven stress, ensuring that the filter element 2 always maintains a flat working state. In addition, when installing the filter element 2, the filter element 2 can enter along the second support platform 163 at the mounting port 2. The second support platform 163 plays a positioning and guiding role during the installation process, helping users or maintenance personnel to quickly and accurately embed the filter element 2 into the installation position.

[0060] In some embodiments, refer to Figure 3 , 5 The air intake adjustment component 3 includes: two fan-shaped end plates 31, a rotating shaft 32, and an arc plate 33.

[0061] Specifically, two fan-shaped end plates 31 are spaced apart along the length of the mounting port 12, and the two fan-shaped end plates 31 are provided with a rotating shaft 32 and connected to the air inlet cover 16. The arc plate 33 is connected to the arc edge of the two fan-shaped end plates 31.

[0062] Two fan-shaped end plates 31 are respectively connected to one end of the arc plate 33. The fan-shaped end plates 31 and the arc plate 33 together constitute the general shape of the air intake regulating component 3. Structurally, the two fan-shaped end plates 31 are spaced apart along the length of the mounting port 12, which is equivalent to the "side support skeleton" of the air intake regulating component 3, while the arc plate 33 is connected to the arc edges of the two fan-shaped end plates 31, which is equivalent to the "arc-shaped shielding surface" of the air intake regulating component 3. The three together form a "curved cylindrical" overall structure. When the air intake regulating component 3 is in the first position, the air intake regulating component 3 abuts against the first support platform 162, and the rotating shaft 32 drives the two fan-shaped end plates 32 and the arc plate 33 of the air intake regulating component 3 to close the external circulation air intake port 14; when the air intake regulating component 3 is in the second position, the air intake regulating component 3 abuts against the second support platform 163, and the rotating shaft 32 drives the two fan-shaped end plates 32 and the arc plate 33 of the air intake regulating component 3 to close the internal circulation air intake port 13. In addition, a third support platform 164 for supporting the filter element 2 is provided on each of the two opposite side walls of the air inlet shroud 16, and the third support platform 164 and the fan-shaped end plate 31 are located on the same side of the filter element 2. It should be noted that the plate-shaped filter element 2 has four sides. One of the opposite sides of the filter element 2 is on the first support platform 162, and the other side is on the second support platform 163. The remaining two sides are placed on the third support platform 164. The first support platform 162, the second support platform 163, and the third support platform 164 jointly support the filter element 2, so that the filter element 2 always maintains the correct position and will not move.

[0063] In addition, the rotating shaft 32 is the core component of the air intake adjustment assembly 3 for achieving rotation adjustment, such as Figure 3 As shown, the third support platform 164 is provided with a relief notch 1641 to avoid the rotating shaft 32. The notch of the relief notch 1641 allows the rotating shaft 32 to rotate freely here, accurately matching the rotation trajectory and size of the rotating shaft 32, reserving sufficient rotation space for the rotating shaft 32, avoiding direct interference between the rotating shaft 32 and the third support platform 164, and also helping to maintain the coaxiality of the rotation of the rotating shaft 32 through the action of the edge of the relief notch 1641.

[0064] In some embodiments, refer to Figure 4 The air conditioning unit assembly 10 also includes a cover plate 4, which is snapped onto the mounting port 12.

[0065] After the filter element 2 is installed, the cover plate 4 is tightly fastened to the installation port 12 by a snap-fit ​​connection, forming a reliable sealing structure at the installation port 12. The cover plate 4 can effectively prevent dust and debris from outside the air conditioning unit assembly 10 from entering the interior of the housing 1 through the gap of the installation port 12, thus reducing the filtration burden on the filter element 2, while ensuring the cleanliness of the air conditioning system and reducing the risk of component failure due to the accumulation of impurities.

[0066] Furthermore, the cover plate 4 is snapped onto the installation port 12, which also ensures that the filter element 2 will not loosen under the impact of vehicle driving or airflow. In addition, the snap-fit ​​connection makes it more convenient and efficient for users or maintenance personnel to replace the filter element 2 in the future.

[0067] According to the embodiment of the present utility model, the vehicle body assembly 20, such as Figure 7 As shown, it includes: a front body assembly 30 and an air conditioning unit assembly 10. The air conditioning unit assembly 10 is located on the rear side of the front body assembly 30 and is centered relative to the front body assembly 30.

[0068] The air conditioning unit assembly 10 is located on the rear side of the front bulkhead assembly 30 and the front side of the engine, making full use of the limited space between them to maximize the utilization of the interior space. Secondly, the air conditioning unit assembly 10 is located in the middle of the front bulkhead assembly 30, which reduces the proportion of the air conditioning unit assembly 10 in the lateral space of the vehicle 100. When the air conditioning unit assembly 10 delivers air, the duct distance for the air to reach each air outlet of the vehicle 100 is also reduced, which reduces the energy loss of the air during the delivery process and improves the overall efficiency of the air conditioning unit assembly 10.

[0069] According to the embodiment of the present utility model, the vehicle 100, such as Figure 4 As shown, the vehicle body assembly 20 includes the embodiment described above.

[0070] According to the vehicle 100 of this utility model embodiment, by setting the air conditioning box assembly 10 with the structure of the above embodiment, the number of filter elements 2 and the space occupied by the integrated block filter element 2 are shared by the internal circulation channel and the external circulation channel, thereby reducing the cost, improving the convenience of disassembly, effectively improving the user's disassembly experience and reducing maintenance costs.

[0071] The space occupied by the air conditioning unit assembly 10 can be reduced, and its installation in the vehicle can moderately increase the legroom of the driver and passenger seats, thereby improving passenger comfort.
