Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and specifically relates to an air conditioning top cover assembly and a rail vehicle air conditioning unit. Background Technology

[0002] The air conditioning unit for rail vehicles consists of a casing, within which a partition divides it into an indoor cavity and an outdoor cavity. The indoor cavity houses components such as the evaporator and blower, while the outdoor cavity houses components such as the compressor, condenser, and condenser fan. For ease of maintenance, the top plate of the air conditioning unit casing typically consists of multiple individually detachable air conditioning covers arranged side-by-side. Opening these covers allows maintenance personnel to easily access and inspect the internal components of the air conditioning unit.

[0003] The top cover of the air conditioning unit on a rail vehicle is generally made of stainless steel or aluminum alloy sheet metal and is relatively large in size. A hinge may or may not be installed on one side of the top cover; the top cover needs to be lifted manually by maintenance personnel.

[0004] The top cover of existing air conditioning units is designed without handles. Due to the heavy weight of the top cover and the small gap between the edge and the opening edge of the casing, the top cover is particularly difficult to open, and it is easy to cut your hand on the sheet metal edge when opening the top cover. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an air conditioner top cover assembly that allows for easy opening of the air conditioner top cover and avoids cutting hands, and to provide a rail vehicle air conditioning unit with the air conditioner top cover assembly installed.

[0006] To solve the above-mentioned technical problems, the first technical solution adopted by this utility model is:

[0007] An air conditioner top cover assembly includes a top cover body. The first side of the top cover body connected to the air conditioner unit housing has a downward first mounting edge, and the second side adjacent to other top covers has a downward second mounting edge. At least one notch is provided on the first mounting edge and the second side of the top cover body, respectively. A handle covering part of the notch area is installed at the notch. An obstruction opening for hand insertion is formed in the unobstructed notch area outside the handle. An arc-shaped structure for hand contact is provided on the side of the handle facing the obstruction opening.

[0008] Furthermore, the handle includes a long strip of metal plate installed on the side of the notch that is closed, with first mounting holes at both ends. The first mounting holes are fixedly connected to the first mounting edge or the top cover body by fasteners, and the handle body located in the notch area has the arc-shaped structure.

[0009] Further, a fixing member is installed at the notch, the fixing member is arranged around the notch, and the fixing member is fixedly connected to the first mounting edge or the second mounting edge.

[0010] Further, the fixing member is U-shaped and welded to the first mounting edge or the second mounting edge;

[0011] Alternatively, the fixing part is "ji" shaped, and second mounting holes are formed in the flanges at both ends, and the second mounting holes are fixed to the first mounting edge or the second mounting edge through fasteners.

[0012] Further, the handle includes a long strip-shaped metal plate and a U-shaped mounting member. Flanges extending downward are provided at both ends of the handle, and the two flanges are fixedly welded to the two side edges of the mounting member. After the metal plate is welded to the mounting member, it is then fixedly welded to the first mounting edge or the top cover body.

[0013] Further, the handle is installed inside the first mounting edge and the top cover body.

[0014] Further, the handle is made of a stainless steel plate.

[0015] Further, the arc-shaped structure is formed by integrally extending outward from one side of the handle body and then bending backward at 180°; or, the arc-shaped structure is formed by integrally extending outward from one side of the handle body and bending inward in an arc shape.

[0016] Further, an anti-slip structure is provided on the outer surface of the arc-shaped structure.

[0017] The second technical solution of the present invention is:

[0018] An air-conditioning unit for a rail vehicle includes a housing, and the air-conditioning top cover assembly as described above is installed on the housing.

[0019] In summary, an air-conditioning top cover assembly and an air-conditioning unit for a rail vehicle provided by the present invention have the following beneficial effects compared with the prior art:

[0020] (1) The present invention can design different notch areas on the first mounting edge and the top cover body respectively according to the spatial characteristics between its long and short sides and the adjacent top cover or housing, leaving enough operating space for the fingers of maintenance personnel at the position where the handle is installed. This not only facilitates the maintenance personnel to apply force under the handle at different positions of the air-conditioning top cover, but also facilitates opening the air-conditioning top cover.

[0021] (2) Since the position of the handle that contacts the hand is designed as an arc-shaped structure, the present invention can effectively avoid cutting the fingers when the hand is inserted, ensuring the safety of maintenance personnel during operation.

[0022] (3) The handle structure of the air conditioner top cover assembly of this utility model is simple, convenient to manufacture and process, low in cost, and can be welded or riveted to the air conditioner top cover.

Therefore, they should not be construed as limitations on this utility model.

[0039] 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] Example 1:

[0041] like Figure 1 As shown, this utility model provides an air conditioner top cover assembly, which is installed on the housing of an air conditioning unit. Multiple air conditioner top cover assemblies 1 are arranged side by side to form the top plate of the housing. The air conditioner top cover assembly 1 includes a top cover body 11. The first side 12 (i.e., the short side) of the top cover body 11 connected to the housing has a downward first mounting edge 13, and the second side 14 (i.e., the long side) adjacent to other top covers has a downward second mounting edge 15.

[0042] like Figures 1 to 7 As shown, in this embodiment, at least one notch is provided on each of the first mounting edge 13 and the two second side edges 14 of the top cover body 11, namely two first notches 2 provided on the first mounting edge 13 and two second notches 3 provided on the second side edges 14 of the top cover body 11.

[0043] like Figure 2 and Figure 3As shown, the first notch 2 is formed by an upward indentation from the bottom edge of the first mounting edge 13. Figure 4 As shown, the second notch 3 is formed by recessing from the edge of the second side 14 toward the center of the top cover body 11. A handle 4 is installed at the first notch 2 and the second notch 3, partially covering the notch area. The handle 4 only covers a portion of the notch area, creating a clearance opening 5 for hand insertion in the uncovered notch area outside the handle 4. An arc-shaped structure 6 is provided on the side of the handle 4 facing the clearance opening 5, allowing contact with the hand.

[0044] By adopting the above structure, different notch areas can be designed on the first mounting edge 13 and the top cover body 11 according to the spatial characteristics between the long and short sides of the top cover body 11 and the adjacent top cover or shell. For example, since there is sufficient external space on the first side 12 of the air conditioner top cover 1, the first notch 2 is opened on the first mounting edge 13. Since the second side 14 of the air conditioner top cover 1 is arranged side by side with the adjacent top cover, the external space on the second side 14 is obviously insufficient, so the second notch 3 is opened on the top cover body 11. In this way, whether it is the long side or the short side of the air conditioner top cover 1, sufficient operating space can be left for the fingers of maintenance personnel at the position of the handle 4. This not only makes it convenient for maintenance personnel to apply force under the handle 4 from different positions on the air conditioner top cover 1, but also makes it easy to open the air conditioner top cover 1. At the same time, since the part of the handle 4 that contacts the hand is designed with an arc-shaped structure 6, it can also effectively prevent the fingers from being cut when the hand is inserted, ensuring the safety of maintenance personnel.

[0045] like Figures 2 to 7 As shown, in this embodiment, it is further preferred that only one handle 4 is installed at the first notch 2. The handle 4 includes a long strip metal plate 41, preferably made of stainless steel, which is installed on the closed side of the first notch 2, that is, only covering the area near the closed side. This is equivalent to the side edge of the metal plate 41 with the arc structure 6 protruding into the area of ​​the first notch 2 after installation. The area below the metal plate 41 forms a clearance opening 5. The maintenance personnel can insert their fingers into the clearance opening 5 below the handle 4 and apply upward force to lift the air conditioner top cover 1. At the same time, since the side edge of the arc structure 6 protrudes into the area of ​​the first notch 2, when the maintenance personnel insert their fingers, their fingers can only touch the arc structure 6 and will not touch the first mounting edge 13, effectively avoiding hand cuts.

[0046] Specifically, each end of the metal plate 41 has a first mounting hole 42, and the first mounting holes 42 are fixedly connected to the first mounting edges 13 by fasteners. More preferably, a riveting method is used, with the first mounting holes 42 and the first mounting edges 13 fixedly connected by rivets 7. The handle 4 body located within the area of ​​the first notch 2 has an arc-shaped structure 6, that is, the arc-shaped structure 6 is only positioned between the two first mounting holes 42. To avoid cutting hands, the first mounting edges 13 on both sides of the first notch 2 are further processed into rounded corners.

[0047] like Figures 2 to 4 As shown, in this embodiment, it is further preferred that the handles 4 are all installed on the inner side of the first mounting edge 13, and the handles 4 are fixed from the outer side of the first mounting edge 13 using rivets 7. In this way, it is not only convenient to fix the handles 4, but also ensures that when maintenance personnel insert their fingers from the clearance opening 5, they can only touch the arc-shaped structure 6 on one side of the handle 4, and will not touch the first mounting edge 13 and the top cover body 11, thus further effectively avoiding hand cuts.

[0048] like Figure 5 and Figure 6 As shown, the arc-shaped structure 6 is formed by extending outward from one side of the handle body and then bending it in the opposite direction at 180°. This bending process leaves an extended portion that fits snugly against the metal plate 41, further enhancing the overall structural strength of the handle 4. Alternatively, the arc-shaped structure 6 can be formed by extending outward from one side of the handle body and then bending it inward in an arc shape. This handle 4 structure, formed by integrally bending a metal plate, is not only convenient to manufacture and low in cost, but also has good practical performance and can fully meet the requirements for applying force to the handle 4.

[0049] In this embodiment, it is further preferred that an anti-slip structure (not shown in the figure) is provided on the surface of the arc-shaped structure 6. The anti-slip structure can be a diamond pattern or a plurality of arranged depressions that cooperate with the fingers, the shape of the depressions being adapted to the shape of the fingers.

[0050] like Figure 4 As shown, in this embodiment, it is further preferred that the handle 4 described above is also installed at the second notch 3. The first mounting holes 42 at both ends of the handle 4 are fixedly connected to the top cover body 11 at the second side 14 by rivets 7. The handle 4 is also installed on the inner side of the top cover body 11. After installation, one side of the metal plate 41 with the arc-shaped structure 6 protrudes into the area of ​​the second notch 3, forming a clearance opening 5 in the lateral area of ​​the metal plate 41. The maintenance personnel can insert their fingers into the clearance opening 5 on one side of the handle 4, extend them to the bottom of the handle 4, and apply upward force to lift the air conditioner top cover 1.

[0051] like Figure 4 As shown, in addition to the handle 4 mentioned above, a fixing member 8 is further installed at the second notch 3. The fixing member 8 is arranged around the second notch 3 and is fixedly connected to the second mounting edge 15. The fixing member 8 not only improves the structural strength of the second notch 3, but also prevents fingers from being inserted too deeply and touching the components below the air conditioner top cover 1, thus avoiding finger injuries and providing protection. Of course, installing only the handle 4 at the first notch 2 is sufficient to meet the force application requirements at this location, but an additional fixing member 8 can be installed to further strengthen the structural strength of the first mounting edge 13 at the first notch 2.

[0052] Among them, the fixing member 8 is further preferably in a "C" - shaped structure. There is an opening 9 corresponding to the second notch 3 on the second mounting edge 15. The second mounting edge 15 is disconnected at the position of the second notch 3. Both ends of the "C" - shaped fixing member 8 have flanges 81. A second mounting hole 82 is provided on each flange 81 at each end. The second mounting hole 83 and the corresponding second mounting edge 15 are fixedly connected by fasteners. More preferably, in a riveting manner, the second mounting hole 83 and the second mounting edge 15 are fixedly connected by a rivet 7.

[0053] In this embodiment, another implementation manner is also provided for the fixing member 8. The fixing member 8 can also be in a U - shaped structure and be directly welded to the second mounting edge 15.

[0054] In this embodiment, the fixing member 8 and the handle 4 are installed separately, so that the handle 4 installed on the first notch 2 and the second notch 3 can have the same structure, and then the fixing member 8 is installed separately according to needs. This is beneficial to improving the versatility of the handle 4 and also beneficial to reducing the installation difficulty.

[0055] After adopting the above - mentioned scheme, the following advantages are achieved:

[0056] 1. The air - conditioner top - cover assembly can design different notch areas on the first mounting edge and the top - cover main body respectively according to the spatial characteristics between its long and short sides and the adjacent top - cover or shell, leaving enough operating space for the fingers of maintenance personnel at the position where the handle is installed. This not only facilitates the maintenance personnel to apply force under the handle 4 at different positions of the air - conditioner top - cover, but also facilitates opening the air - conditioner top - cover.

[0057] 2. Since the position on the handle that contacts the hand is designed in an arc - shaped structure, the air - conditioner top - cover assembly can effectively avoid cutting the fingers when the hand is inserted, ensuring the safety of maintenance personnel during operation.

[0058] 3. The handle structure in the air - conditioner top - cover assembly is simple, convenient for production and processing, with low cost. It can be welded or riveted to the air - conditioner top - cover, not restricted by the material of the air - conditioner top - cover, and has good practical effects.

[0059] 4. In the air - conditioner top - cover assembly, the fixing member and the handle 4 are installed separately, so that the handle installed on the first notch and the second notch can have the same structure, and then the fixing member is installed separately according to needs. This is beneficial to improving the versatility of the handle and also beneficial to reducing the installation difficulty.

[0060] Embodiment Two:

[0061] Such as Figure 8As shown, unlike Embodiment 1, in this embodiment, the handle 4 includes a long strip metal plate 43 and a U-shaped mounting member 44. The metal plate 43 has downward-facing folded edges 45 at both ends. The metal plate 43 spans across the mounting member 44, and the two folded edges 45 are welded to the two sides of the mounting member 44 to form an integral structure. After welding the metal plate 43 to the mounting member 44, it is then welded to the first mounting edge 13 or the top cover body 11. This facilitates the installation of the handle 4 to the air conditioner top cover 1. One side of the metal plate 43 has the same arc-shaped structure 6 as described in Embodiment 1.

[0062] To increase the welding area between the handle 4 and the top cover body 11, this embodiment further includes a downwardly recessed structure on both sides of the mounting member 45. The flange 45 at the end of the metal plate 43 is butt-welded to the edge of the mounting member 45 at the recessed area. The upper surface of the metal plate 43 is on the same plane as the upper surface of the area outside the recess of the mounting member 45. When welding with the top cover body 11, both sides of the mounting member 45 are located on both sides of the second notch 3. The side of the metal plate 43 with the arc-shaped structure 6 covers part of the area of ​​the second notch 3, that is, within the area of ​​the arc-shaped structure 6 and the second notch 3. Both the metal plate 43 and the mounting member 45 can contact and weld with the inner surface of the top cover body 11.

[0063] Preferably, in this embodiment, the handle 4 structure as described in Embodiment 1 is installed at the first notch 2, while the handle 4 structure described in this embodiment is installed at the second notch 3.
