Detailed Embodiments

[0033] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will provide a detailed description of the technical solutions of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0034] Embodiment 1:

[0035] As Figure 1 shown, to solve the problem that the duct assembly of a mobile air conditioner cannot be fixed when passing through a window, the present utility model provides a fixing structure, which can be used for fixing the duct assembly and can fix the duct assembly on structures such as windows.

[0036] Specifically, the fixing structure includes a first fixing frame 1 and a second fixing frame 2 that can be buckled together to fix the pipeline. Considering the placement of the fixing structure and the subsequent sealing at the window, in this embodiment, the first fixing frame 1 and the second fixing frame 2 can form a rectangular fixing structure after being buckled together. For the convenience of pipeline passing through and fixing, in this embodiment, at least one semi-circular notch 3 is provided on both the first fixing frame 1 and the second fixing frame 2. It should be noted here that when fixing one pipeline, only one notch 3 can be set; when fixing two pipelines, two notches 3 are required; when fixing three or more pipelines, three or more notches 3 can be opened, and all the notches 3 are arranged side by side to facilitate fixing at least one pipeline at the same time.

[0037] When the first fixing frame 1 and the second fixing frame 2 are buckled together relatively, all the notches 3 are spliced together to form at least one pipeline fixing part 4 for fixing the pipeline.

[0038] The fixing structure provided by the present utility model can fix the duct assembly on structures such as windows, and the installation is simple and convenient.

[0039] To simplify the processing procedure, in this embodiment, the specifications and shapes of the first fixing frame 1 and the second fixing frame 2 can be exactly the same, and the specifications and shapes of the set notches 3 are also exactly the same. The pipeline can be directly clamped by the notch 3 to realize the fixing of the pipeline.

[0040] However, this method of directly clamping the pipeline by the notch 3 has the risk that the pipeline is easily pulled out of the fixing structure when the pipeline is under tension.

[0041] Embodiment 2:

[0042] As Figure 2 and Figure 3As shown in the figure, considering the convenient disassembly, assembly and operation of the first fixing bracket 1 and the second fixing bracket 2, in this embodiment, one end of the first fixing bracket 1 and the second fixing bracket 2 is rotatably connected through a rotating shaft 5, and the other end is detachably connected through a buckle assembly 6.

[0043] That is to say, a rotating shaft 5 is provided at one end of the first fixing bracket 1 and the second fixing bracket 2. By using the rotating shaft 5, relative rotation between the two can be realized. When pipeline fixing is required, the first fixing bracket 1 can be lifted upward to open the pipeline fixing part 4, then the pipeline is clamped into the notch 3, and then the first fixing bracket 1 is pressed downward so that the notches 3 on the two fixing brackets both clamp the pipeline. Finally, the other ends of the first fixing bracket 1 and the second fixing bracket 2 are locked and fixed by using the buckle assembly 6, thereby completing the pipeline fixing operation, which is not only convenient and simple, but also convenient for the storage of the fixing structure.

[0044] It should be noted that the buckle assembly 6 can be realized by using the structure in the prior art. For example, a buckle part is provided on the first fixing bracket 1; then a rotatable hook part is provided on the second fixing bracket 2, and then the hook part is buckled into the buckle part to realize the buckle connection. Of course, other structural forms can also be adopted, as long as it is a detachable buckle structure, and it is not specifically limited in this embodiment.

[0045] Of course, the connection structure between the first fixing bracket 1 and the second fixing bracket 2 is not limited to the connection method of the rotating shaft 5 and the buckle assembly 6. It can also be connected and disassembled by providing buckle assemblies 6 at both ends, or by using pin shafts, snap connections, plug connections, etc. The present utility model does not make specific limitations on this.

[0046] Embodiment 3:

[0047] In order to solve the problem that the pipeline is directly clamped through the notch 3 in Embodiment 1 and is not firmly fixed and is easy to come out, in this embodiment, the structure of the notch 3 is improved.

[0048] Specifically, as Figure 3 、 Figure 4 and Figure 5 shown, a plurality of arc-shaped first pipe clamping rib strips 7 are arranged in the notch 3 on the first fixing bracket 1, and a plurality of arc-shaped second pipe clamping rib strips 8 are arranged in the notch 3 on the second fixing bracket 2.

[0049] Considering that the commonly used air duct components of mobile air conditioners are all made of corrugated hoses, and there are grooves 300 at intervals on the corrugated hoses. Therefore, in this embodiment, by arranging a plurality of pipe clamping rib strips in the notch 3, the pipe clamping rib strips are clamped in different grooves 300 of the corrugated hose, thereby improving the pipe clamping stability of the fixing structure for the air duct component and ensuring the stability of the air duct component of the mobile air conditioner.

[0050] AsFigure 6 As shown, considering that when the air duct assembly passes through a window or a car window, there is a bending situation, resulting in local folding wrinkles, and the groove 300 spacing at the bending position is small and it is not easy to set the rib strips. Moreover, too many rib strips will affect the folding effect. In order to facilitate the accommodation of the wrinkles of the air duct assembly, in this embodiment, the number of the second pipe clamping rib strips 8 on the second fixing frame 2 with more wrinkles at the bottom of the air duct assembly is set one less, and the number of the first pipe clamping rib strips 7 on the first fixing frame 1 clamped to the top of the air duct assembly is set more than the number of the second pipe clamping rib strips 8 on the second fixing frame 2, so as to reserve space for the folding of the air duct assembly while ensuring the stable clamping of the air duct assembly.

[0051] Considering the structure of the air duct assembly, in order to realize the pipeline guiding and fixing, in this embodiment, all the second pipe clamping rib strips 8 are arranged in one-to-one correspondence with the same number of the first pipe clamping rib strips 7.

[0052] The distance between two adjacent first pipe clamping rib strips 7 is equal to the distance of the groove 300 of the pipeline to be fixed.

[0053] It should be noted here that in this embodiment, as Figure 5 shown, the number of the first pipe clamping rib strips 7 on the first fixing frame 1 is three, and the distance between the three first pipe clamping rib strips 7 is equal to or close to the spacing of the groove 300 on the air duct assembly. It should be noted here that through the handboard verification by the inventor, it is found from the physical object of the ABS handboard sample printed by the 3D printer that the number of the first pipe clamping rib strips 7 on the first fixing frame 1 is at least three. When it is less than three, there is a risk that the air duct assembly will fall off under the pulling force and the fixing is not firm.

[0054] As Figure 4 shown, in order to facilitate the placement of the pipeline wrinkles, the number of the second pipe clamping rib strips 8 arranged on the second fixing frame 2 is two. First of all, these two second pipe clamping rib strips 8 correspond to the first and second positions among the three first pipe clamping rib strips 7. When the first fixing frame 1 and the second fixing frame 2 are buckled together, these two second pipe clamping rib strips 8 and two of the first pipe clamping rib strips 7 can be combined together to form a ring, and the extra rib strip among the first pipe clamping rib strips 7 corresponds to the smooth position of the notch 3 on the second fixing frame 2. During use, the smooth position of the notch 3 on the second fixing frame 2 is used for the placement of the wrinkle position of the air duct assembly.

[0055] Embodiment 4:

[0056] Considering the overall stretching state at the top of the air duct assembly after installation, its groove 300 can be completely exposed and can be integrally fixed. Therefore, as Figure 5 shown, in this embodiment, the first pipe clamping rib strip 7 is arranged through along the circumferential direction of the notch 3, and the first pipe clamping rib strip 7 gradually increases from one side of the notch 3 to the other side.

[0057] Specifically, considering the structure in Embodiment 2 where the first fixing frame 1 and the second fixing frame 2 are connected by a rotating shaft 5 on one side and a buckle assembly 6 on the other side, when installing the air duct assembly, the fixing frame near the rotating shaft 5 will contact the air duct assembly first. To enable the rib to quickly snap into the groove 300 and for pipe clamping guidance, in this embodiment, the side of the first pipe clamping rib 7 near the rotating shaft 5 is the lowest, while the first pipe clamping rib 7 near the buckle assembly 6 is the highest.

[0058] The utility model makes the air duct fixed stably and assembled conveniently by setting the first pipe clamping rib into a special structure with a shallower front and a deeper rear (the height increases in sequence) and the rib positions in three regions (three ribs).

[0059] Embodiment 5:

[0060] Although there is a certain space reserved in the notch 3 of the second fixing frame 2 in Embodiment 3 for placing the wrinkled position of the air duct assembly, in order to further facilitate the accommodation of the wrinkles, in this embodiment, the structure of the second pipe clamping rib 8 is specifically defined.

[0061] In this embodiment, as Figure 4 shown, the second pipe clamping rib 8 is arranged along the circumferential direction of the notch 3, and the second pipe clamping rib 8 is a segmented structure, including a first rib segment 81 and a second rib segment 82, with a gap left between the first rib segment 81 and the second rib segment 82.

[0062] By leaving a gap between the first rib segment 81 and the second rib segment 82, it is also for facilitating the accommodation of the wrinkled position of the air duct assembly.

[0063] Embodiment 6:

[0064] When the air duct assembly is snapped into the pipe fixing part 4 surrounded by the notch 3, the air duct assembly can be seen outside the window or vehicle window. To prevent the air duct assembly from protruding and affecting the appearance after installation, in this embodiment, a retaining ring 9 is provided at one end of the notch 3 on the first fixing frame 1 and the second fixing frame 2. Specifically, the retaining ring 9 is arranged along the circumferential direction of the notch 3, and the height of the retaining ring 9 is higher than the heights of the first pipe clamping rib 7 and the second pipe clamping rib 8.

[0065] Embodiment 7:

[0066] The fixing structures in the above multiple embodiments are all applicable to the windows of residences. When the air duct assembly is installed on a vehicle window, considering that the cross-section of the vehicle window is very small and it is impossible to stably place the first fixing frame 1 and the second fixing frame 2, and in order to facilitate the fixing of the fixing structure on the vehicle window, in this embodiment, as Figure 3 and Figure 7As shown in the figure, a first fixing groove 10 is provided on one side of the first fixing frame 1 away from the notch 3. Specifically, that is, a downwardly recessed first fixing groove 10 is provided on the top end face of the first fixing frame 1. A convex rubber strip 40 is provided in the first fixing groove 10. It should be noted here that the convex rubber strip 40 has a T-shaped structure, including a base and a convex strip. The base is snapped into the first fixing groove 10, and then the convex strip can be snapped into the card slot at the top of the window. The base can be fixed in the first fixing groove 10 by interference fit, bonding or other means.

[0067] As a further improvement of the present invention, a second fixing groove 20 is provided on one side of the second fixing frame 2 away from the notch 3. That is, an inwardly recessed second fixing groove 20 is provided on the bottom end face of the second fixing frame 2. A concave rubber strip 50 is provided in the second fixing groove 20. It should be noted here that the concave rubber strip 50 has a U-shaped structure, including a bottom beam and a groove part. The specification of the groove part is shaped like the window glass. The bottom beam is snapped into the second fixing groove 20, and the groove part is for inserting the window glass. The bottom beam can be fixed in the second fixing groove 20 by interference fit, adhesive or other means. For example, the conventional thickness of the window glass is 5-8 mm. Then the width of the groove part is also 5-8 mm, and the groove part of the concave rubber strip is directly installed on the window glass.

[0068] The fixing structure of the present invention can cooperate with the top and bottom structures of the window through the concave and convex rubber strips, so as to fix the air duct assembly on the window and protect the window glass.

[0069] Embodiment 8:

[0070] In order to ensure that when the fixing structure passes through the window or the window, although the air duct assembly is fixed, there is a problem of cold and air leakage when the window or the window cannot be closed. In this embodiment, the fixing structure further includes a baffle 60. The baffle 60 has a plate-like structure, and a notch is provided at its bottom. The notch is used to accommodate the first fixing frame 1 and the second fixing frame 2. The length and height of the notch are equal to the length and height when the first fixing frame 1 and the second fixing frame 2 are butted together. Then the overall specification of the baffle 60 is the same as the corresponding window specification or the specification of the area where the corresponding window cannot be closed, thereby ensuring the cold and air leakage problem of the window or the window when the fixing structure fixes the air duct assembly.

[0071] And in order to facilitate the fixing of the baffle 60, a third fixing groove 30 is provided at the top of the first fixing frame 1. The notch position of the baffle 60 is just snapped into the third fixing groove 30, thereby realizing the sealing of the fixing structure with the window or the window.

[0072] When the fixing structure is applied to the window, the third fixing groove 30 is opened beside the first fixing groove 10.

[0073] The fixing structure provided by the present utility model fixes the air duct assembly through rib strips, which is simple and convenient to install, and is fixed on the window through a rubber strip structure; with a unique rib strip structure and a unique structure for fixing on the window, it solves the problems of air duct fixing and glass fixing. By setting a baffle, when the air duct assembly is installed on the glass, the remaining space caused by window opening can be blocked to avoid cold and air leakage.

[0074] Embodiment 9:

[0075] An air duct assembly provided by the present utility model includes a corrugated exhaust air inlet and outlet hose and a fixing structure for fixing the corrugated exhaust air inlet and outlet hose.

[0076] Specifically, as Figure 1 and Figure 2 shown, the corrugated exhaust air inlet and outlet hose includes a corrugated exhaust air inlet hose 100 and a corrugated exhaust air outlet hose 200; both the corrugated exhaust air inlet hose 100 and the corrugated exhaust air outlet hose 200 are made of corrugated pipes, and have a number of grooves 300 thereon.

[0077] The fixing part 4 of the fixing structure is used to fix the corrugated exhaust air inlet and outlet hose, and the rib strips in the air duct fixing part 4 are used to be clamped into the grooves 300 to achieve stable fixing of the air duct assembly.

[0078] During installation, the corrugated exhaust air inlet hose 100 and the corrugated exhaust air outlet hose 200 are respectively placed on two arc-shaped notches 3 of the second fixing bracket 2 and are in contact with the second air duct clamping rib strip 8. Rotate the first fixing bracket 1, and the first air duct clamping rib strip 7 on the first fixing bracket 1 guides the air duct assembly to be embedded. Finally, the first fixing bracket 1 and the second fixing bracket 2 are fixed through the buckle assembly 6. At this time, a total of three rib strips are enclosed by the first fixing bracket 1 and the second fixing bracket 2, including two full-circle rib strips and one half-circle rib strip. The X, Y, and Z axes of the air duct assembly are completely fixed, and due to the reserved space, the air duct assembly can be adjusted and rotated downward.

[0079] Embodiment 10:

[0080] In this embodiment, a mobile air conditioner provided by the present utility model includes the above-mentioned air duct assembly.

[0081] When the mobile air conditioner or the mobile unit is working, an external air duct assembly is usually connected for heat exhaust. The air duct assembly can be fixed through the fixing structure and can be installed on the window or the window, protecting the window glass and avoiding cold and air leakage at the same time.

[0082] In this embodiment, the air duct assembly is composed of parts such as a baffle 60, a convex rubber strip 40, a concave rubber strip 50, a first fixing bracket 1, a second fixing bracket 2, a buckle assembly 6, and a rotating shaft 5.

[0083] As Figure 4As shown, two arc-shaped notches 3 of the second fixing bracket 2 in this embodiment are respectively provided with two sections of arc-shaped ribs, specifically the second pipe clamping ribs 8. The second pipe clamping ribs 8 are shaped to fit the air duct assembly, and the second pipe clamping ribs 8 are of a discontinuous structure and are arranged in sections. By arranging a break in the middle of the second pipe clamping ribs 8, when installing the air duct assembly, the air duct assembly is first fully unfolded to expose the groove 300 of the air duct assembly, and the air duct assembly is installed on the second fixing bracket 2. At this time, the groove 300 of the air duct assembly cooperates with the second pipe clamping ribs 8 on the second fixing bracket 2 through the guidance of the second pipe clamping ribs 8 to fix the air duct assembly.

[0084] When the air duct assembly needs to be installed on the window, since the window will finally rise to fix the fixing structure, at this time the air duct assembly will bend downward appropriately, and the unfolded part of the air duct assembly will shrink to form wrinkles, as Figure 6 shown. The break in the middle of the second pipe clamping ribs 8 and the setting of one less rib are both for reserving a structure to store the shrunk part of the air duct assembly.

[0085] As Figure 5 shown, one complete arc-shaped first pipe clamping rib 7 is respectively arranged on two arc-shaped notches 3 of the first fixing bracket 1 in this embodiment. The interval between adjacent two first pipe clamping ribs 7 is shaped to fit the air duct assembly. The first pipe clamping rib 7 gradually increases in height from one side of the rotating shaft 5 to the side of the buckle assembly. When installing the air duct assembly, the air duct assembly is first fully unfolded to expose the groove 300 of the air duct assembly, and is first installed on the second fixing bracket 2. At this time, the first fixing bracket 1 rotates around the metal rotating shaft 5 to the side of the buckle assembly 6 for assembly. When contacting the air duct assembly, the first pipe clamping rib 7 on the rotating shaft 5 side of the first fixing bracket 1 first overlaps with the groove 300 of the air duct assembly. By slowly increasing the height of the first pipe clamping rib 7, through the gradually increasing first pipe clamping rib 7, the air duct assembly is gradually guided to the expected position and finally fixed.

[0086] In this embodiment, the installation process of the air duct assembly of the mobile air conditioner is convenient for assembly, avoiding the risk that when the first pipe clamping rib 7 of the same height is assembled, when the first fixing bracket 1 rotates, the first pipe clamping rib 7 is too protruding and easily squeezes the air duct assembly, causing the air duct assembly to deform, and the air duct assembly is also easily not installed in place, and in severe cases, the parts are damaged, and there is an easy risk of extrusion deformation of the air duct assembly.

[0087] When the air duct assembly is installed on the window, when the mobile air conditioner is in use, first lower the window partway. The concave rubber strip 50 and the convex rubber strip 40 are shaped to conform to the structure on the window. First, place the concave rubber strip 50 on the second fixing bracket 2 on the window glass, and then raise the window. During this process, the convex rubber strip 40 aligns with the card slot at the top of the window. When the window is raised to the upper position, due to the elasticity of the rubber strip itself, the window is protected. At this time, the window completely fixes the fixing structure, and the air outlet faces outwards. Finally, place the baffle 60 in the third fixing groove 30 reserved on the fixing structure, as Figure 7 shown, to block the remaining position of the window.

[0088] When the mobile air conditioner is working, as Figure 1 shown, the two air ducts are respectively connected to the condensing end of the air conditioner. One is for air intake, and one end is for exhausting hot air for heat dissipation. The other ends of the two air ducts use a fixing structure and are fixed to the window through the fixing structure. When the vehicle is parked, the mobile air conditioner can be used inside the vehicle, ensuring cooling inside the vehicle, exhausting air outside the vehicle, and not leaking air or light.
