[0042] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0043] According to a first aspect of an embodiment of the present application, an air duct assembly is provided. Figures 1 to 8 The structure and working principle of the air duct assembly are described in detail.

[0044] According to the air duct assembly provided in the embodiment of the present application, the air duct assembly includes a first plate portion 100, a second plate portion 200 and a third plate portion 300, one side edge of the first plate portion 100 is detachably connected to the second plate portion 200, and the third plate portion 300 is detachably connected to the second plate portion 200 and the first plate portion 100.

[0045] In the embodiment, the third plate portion 300 is formed with an opening area, and a plurality of air outlet holes penetrating the third plate portion 300 are arranged in the opening area.

[0046] In the embodiment, the second plate portion 200 is formed with an adjustment area, the position of the adjustment area corresponds to the position of the opening area, and a through hole with an adjustable size is provided in the adjustment area;

[0047] In the embodiment, one side edge of the second plate portion 200 is connected to the third plate portion 300 , and the other side edge of the second plate portion 200 is connected to the connection position between the first plate portion 100 and the second plate portion 200 .

[0048] Thus, the air duct assembly provided in the embodiment of the present application, compared with the prior art, splits the complete air duct bottom plate in the prior art into the first plate portion 100 and the second plate portion 200, and then detachably connects the first plate portion 100 and the second plate portion 200, and detachably connects the third plate portion 300 to the first plate portion 100 and the second plate portion 200. Thus, the air duct assembly provided in the embodiment of the present application is componentized, thereby facilitating the production and assembly of the air duct assembly, thereby reducing the production difficulty of the air duct assembly and improving the production efficiency of the air duct assembly compared with the prior art.

[0049] Prior to the present application, the air duct components of buses are often made of aluminum, which is usually extruded from a customized mold (i.e., an aluminum extrusion process) to obtain the air duct components of buses. However, due to the size of the air duct components, large-sized aluminum profiles and large molds are required, which reduces the production efficiency of the air duct components, both in terms of mold customization and processing.

[0050] In the embodiment, the present application "breaks the air duct assembly into parts" by changing the air duct base plate of the air duct assembly into two parts, a first plate portion and a second plate portion that are detachably connected. The aluminum extrusion process can still be used, but for each plate portion, since the size of the air duct assembly is smaller, the size of the required mold and the size of the aluminum profile will also be smaller, which will reduce the production time of a single plate portion. In fact, the original air duct assembly is divided into two parts, which are processed separately and then spliced ​​together. Compared with the original air duct assembly, the production time is effectively shortened and the processing cost is also reduced.

[0051] In the embodiment, the detachable connection mentioned in the above description includes but is not limited to connection methods such as connection using fasteners and snap connection, and the specific connection method will be explained in the subsequent description.

[0052] According to the air duct assembly provided in the embodiment of the present application, the first plate portion 100 may include a first plate body and a first flange 110. The first flange 110 may be connected to the first plate body, and the first flange 110 may form a first recess 120 together with the edge of the first plate body, and a portion of the second plate portion 200 may be accommodated in the first recess 120.

[0053] In this way, the air duct assembly provided according to the embodiment of the present application accommodates part of the second plate portion 200 through the first recess 120 jointly formed by the first plate body and the first flange 110, thereby improving the stability of the detachable connection between the first plate portion 100 and the second plate portion 200.

[0054] According to the air duct assembly provided in the embodiment of the present application, the first flange 110 can be detachably connected to the second plate portion 200. In the embodiment, the detachable connection between the first flange 110 and the second plate portion 200 can be used as a fixed connection position of the first flange 110 and the second plate portion 200, and this position can also be, for example, a connection position of the third plate portion 300 with the first plate portion 100 and the second plate portion 200. This will be specifically described in the subsequent description.

[0055] According to the air duct assembly provided in the embodiment of the present application, the second plate portion 200 may include a second plate body and a second flange 210. The first flange 110 may be connected to the second plate body. The second flange 210 may form a second recess 220 together with the edge of the second plate body. Part of the second flange 210 may be accommodated in the first recess 120, and the edge of the first plate portion 100 may be accommodated in the second recess 220.

[0056] According to the air duct assembly provided in the embodiment of the present application, since the second flange 210 and the second plate body form the second recess 220, the edge of the second plate portion 200 is accommodated in the second recess 220, and part of the second flange 210 is accommodated in the above-mentioned first recess 120. In this way, the first recess 120 and the second recess 220 are embedded in each other with the first plate portion 100 and the second plate portion 200, thereby providing better stability for the connection between the first plate portion 100 and the second plate portion 200.

[0057] According to the air duct assembly provided by the embodiment of the present application, the second plate body can protrude toward the side away from the bus to form an inner side facing the bus and an outer side facing away from the bus. In an embodiment, the first flange 110 and the second flange 210 can extend toward the inner side of the second plate body.

[0058] In this way, according to the air duct assembly provided in the embodiment of the present application, the inner side of the second plate body is toward the top of the bus, and the first flange 110 and the second flange 210 are both located on the inner side of the second plate body and will not be exposed to the interior space of the bus, thereby not causing interference to components or personnel in the interior space of the bus.

[0059] According to the air duct assembly provided in the embodiment of the present application, the air duct assembly may also include a first fastener 410, and a portion of the first flange 110, a portion of the second flange 210, and an edge of the third plate portion 300 overlap. The first fastener 410 may pass through a portion of the first flange 110, a portion of the second flange 210, and an edge of the third plate portion 300 to connect the first flange 110, the second flange 210, and the third plate portion 300.

[0060] In the embodiment, the first plate portion 100, the second plate portion 200 and the third plate portion 300 are connected by only one penetration of the first fastener 410, thereby simplifying the structure of the air duct assembly and improving the assembly efficiency of the air duct assembly. In the embodiment, the first fastener 410 can be, for example, a bolt, which can be locked with a nut.

[0061] According to the air duct assembly provided in the embodiment of the present application, the second plate portion 200 may further include a third flange 230, a cavity 240 is defined by the third flange 230, and the third flange 230 may be located on the inner side of the second plate portion 200. The air duct assembly may further include a second fastener 420, a portion of which may be snapped into the cavity 240, and the second fastener 420 may pass through the third plate portion 300 to connect the second plate portion 200 with the third plate portion 300.

[0062] According to the air duct assembly provided in the embodiment of the present application, since the third flange 230 is arranged on the inner side of the second plate portion 200, the third flange 230 provides an installation position for the second fastener 420 by clamping the second fastener 420, so that the second fastener 420 does not need to penetrate the second plate portion 200 to be connected to the third plate portion 300, thereby ensuring the air tightness of the second plate portion 200 and preventing air from discharging from a position outside the adjustment area of ​​the second plate portion 200.

[0063] In an embodiment, Figure 7 As shown, the second fastener 420 may be, for example, a bolt. Since the head of the bolt has a larger size, it can be fastened along the Figure 2 Insert the bolt into the cavity 240 in a direction perpendicular to the paper surface so that the bolt is stuck in the cavity 240, and the third plate portion 300 is opened at a corresponding position for the bolt to pass through, and then a nut is screwed on the bolt on the side of the third plate portion 300 facing away from the second plate portion 200.

[0064] According to the air duct assembly provided in the embodiment of the present application, the second plate portion 200 may further include a slider 500 and a second plate body, a through hole may be opened in the second plate body, and the slider 500 may slide relative to the second plate body to adjust the size of the through hole.

[0065] In an embodiment, the adjustment area on the second plate body may be provided with a plurality of through holes, and the slider 500 may also be provided with a plurality of through holes at the same position. The slider 500 (for example, a waist-shaped hole is provided on the slider itself and connected to the second plate body by bolts) slides relative to the second plate body, thereby changing the overlap between the through holes on the slider 500 and the through holes on the second plate body to adjust the area through which the wind passes. In addition, a speaker sound transmission hole 310 may be provided on the second plate body, and the inner side of the speaker sound transmission hole 310, that is, the inner side of the second plate body, may correspond to the installation of the bus speaker, that is, the speaker is installed in the air duct of the bus, and the speaker may be installed to the second plate body by a plate-shaped bracket and bolts.

[0066] The thickness of the top of the structure of the passenger bus is too short (in the "Z" plane direction of the car), and the upper edge of the side window is relatively higher than that of the bus version. The bottom of the left and right air ducts in the car is lower than the upper edge of the left and right side windows. (Generally, there is a difference of 90mm to 180mm), which does not affect the central aisle in the car, ensuring the ventilation section of the aluminum duct air conditioning. With the installation structure and process, the aluminum duct assembly forms a "Z"-shaped structure with a large duct section. Due to the development cost, cycle and product stability risks, it cannot meet the needs. The aluminum duct assembly is decomposed and spliced ​​by two pieces. The contact surface needs to be increased to promote the stability of the product structure and make the splicing strength reliable.

[0067] The "Z"-shaped structure of the aluminum duct assembly is decomposed into aluminum duct assembly aluminum profiles and side panel aluminum profiles, which are concentrically embedded for positioning, rotation (using the lever principle), multi-point fitting and limiting, and riveted. Then assemble the air outlet slider and speaker bracket. The assembled aluminum duct assembly is easy to install and fix on the vehicle body as a whole, and together with the aluminum duct hanging plate, the top light profile, the top of the vehicle body with an insulation layer, and the upper part of the side enclosure, it forms a closed passenger car air conditioning duct. In the installation environment, the aluminum duct assembly composed of the side panel aluminum profile and the bottom plate aluminum profile in this structure diagram is connected and fixed to the vehicle body through the duct mounting bracket and the hanger. It is suitable for the selection of passenger version bus aluminum ducts.

[0068] Aluminum duct side panel aluminum profiles have special-shaped cross-sections. After extrusion, they become aluminum duct side panel aluminum profiles. The standard length of aluminum profiles is generally 6 meters per piece (can be set according to application requirements). The aluminum duct side panel aluminum profile is equipped with two inverted "V" shaped scale line grooves, forming a "7" shaped structure, and the first groove forms an arc groove.

[0069] In addition, the second groove is a "C"-shaped snap-fit ​​limiting groove.

[0070] The aluminum air duct air outlet slider has a row of waist holes in the middle, and a circular boss is provided in the middle rear position of the middle row. The boss has an internal threaded hole M4 for screwing in the handle bolt. The air outlet slider is embedded in the air outlet slider limit slot. When it coincides with the corresponding aluminum air duct component profile air outlet punching hole, screw in the handle bolt. When the handle bolt is pushed to the rear end, the air outlet is in the maximum ventilation state when it is open. Push the handle bolt in the reverse direction, the misalignment of the slider hole and the bottom plate profile punching hole is reduced, the air outlet hole area is reduced, and the air volume is relatively reduced. When it is pushed to the front end, the air outlet is in the closed state.

[0071] After the aluminum duct assembly is assembled, the bottom plate aluminum profile is punched according to the set elliptical speaker punching style. The middle of the speaker bracket is an elliptical opening, and the elliptical edge is equipped with 4 M4*16 bolts for fixing the speaker. The left side of the bracket is equipped with two mounting circular holes, and the right side is equipped with 2 waist holes. The right left side is fitted with the upper plane of the side plate aluminum profile. The bracket mounting hole and the "V" scale line slot drilling hole are fixed with rivets. The right side of the speaker bracket is connected to the bolt groove (cavity) of the bottom plate aluminum profile with the M6*25 bolt set. The speaker bracket connection also promotes the strengthening of the aluminum duct assembly.

[0072] According to a second aspect of an embodiment of the present application, a bus is provided. The bus may include the air duct assembly as described above, and also include the above beneficial effects, which will not be described in detail here.

[0073] According to the bus provided in the embodiment of the present application, the bus may further include an air duct hanging plate, which may be connected to the top of the bus and may be connected to the air duct assembly. The bus may further include a bracket, which may be connected to the top and may be hinged to the air duct assembly.
