They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0035] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 4 As shown, the utility model provides an anti-detachment installation structure for the side cover of an air-conditioning unit, which is installed on a roof-mounted unit-type air-conditioning unit of a rail vehicle or a large passenger car, and is used to fix the side cover 1 on the shell side panel 3 of the air-conditioning unit 2, and the side cover 1 is installed on the outer side of the shell side panel 3.

[0037] In this embodiment, the air conditioning unit side cover anti-detachment mounting structure includes mounting brackets 4, multiple of which are provided along the length of the air conditioning unit 2. These mounting brackets 4 are fixedly connected to the housing side panels 3. These mounting brackets 4 and housing side panels 3 can be directly welded together, or they can be bolted together. The side cover 1 is fixedly connected to the mounting brackets 4 using fasteners such as bolts, facilitating assembly and disassembly of the side cover 1. Once installed, the mounting brackets 4 are positioned within the side cover 1 to reduce wind resistance on both sides of the air conditioning unit 2.

[0038] In this embodiment, upwardly extending anti-drop hooks 5 are mounted on the mounting bases 4. Anti-drop hooks 5 may be installed on each mounting base 4, or only on some of the mounting bases 4. Corresponding anti-drop holes 6 are formed in the side cover 1. After the side cover 1 is installed, the anti-drop hooks 5 are inserted into the corresponding anti-drop holes 6 to prevent the side cover 1 from falling off. Even if the bolts or other fasteners between the mounting base 4 and the side cover 1 become loose, fall off, or are not properly tightened, the side cover 1 will not fall off the mounting base 4, thereby effectively ensuring the safe operation of the vehicle.

[0039] In this embodiment, preferably, the anti-drop hook 5 is a rod-shaped body, one end of which is welded to the mounting seat 4, and the other end is bent and extended upward, inserted into the anti-drop hole 6 on the side cover 1, and the end of the hanging end extends upward from the anti-drop hole 6.

[0040] To facilitate assembly and disassembly of the side cover 1 and ensure effective anti-detachment, the anti-detachment hook 5 is preferably bent upward at an angle such that the anti-detachment hook 5 can only be released from the anti-detachment hole 6 when the side cover 1 is tilted upward about its rotation center (i.e., the side edge where the top of the side cover 1 meets the housing side panel 3). This ensures that the side cover 1 can only be released from the anti-detachment hook 5 when it is manually tilted upward, and will not fall off or be removed without manual intervention, thereby ensuring the effective cooperation between the side cover 1 and the anti-detachment hook 5.

[0041] like Figure 1 and Figure 2 As shown, in the present embodiment, it is further preferred that the anti-detachment hook 5 is installed on one side of the mounting seat 4, and is composed of three sections connected in sequence, including a first section 51 horizontally extending toward the outer side cover 1, a second section 52 vertically extending upward, and a third section 53 bent in the opposite direction toward the shell side panel 3. The bending angle between the third section 53 and the second section 52 meets the requirement that the anti-detachment hook 5 can only detach from the anti-detachment hole 6 when the side cover 1 is flipped upward around the rotation center, and the connection point between the third section 53 and the second section 52 is higher than the top of the mounting seat 4 in the vertical direction or at the same height, which not only facilitates the disassembly and assembly of the side cover 1, but also ensures the anti-detachment effect.

[0042] In this embodiment, a mounting base inspection opening 7 is also provided on the side cover 1. The mounting base inspection opening 7 is provided corresponding to the mounting base 4 and is located above the mounting base 4. This allows maintenance personnel to observe the installation status of the internal mounting base 4 without removing the side cover 1, such as to check whether bolts and other fasteners are loose or falling off. Furthermore, bolts can be tightened through the mounting base inspection opening 7, meeting bolt tightening requirements, facilitating daily maintenance work, and reducing daily workload. The mounting base inspection opening 7 should be sized to ensure easy viewing and operation, and preferably, an oblong hole is used to increase the operable range.

[0043] In this embodiment, two shock absorber fixing holes 8 are defined in the mounting base 4. A shock absorber 10, a rubber block, is fixedly mounted in each of the shock absorber fixing holes 8 via bolts 9. The mounting base inspection opening 7 is provided in a one-to-one correspondence with the shock absorber fixing holes 8 and is located above the shock absorber fixing holes 8. This further facilitates maintenance personnel in observing the installation of the internal shock absorbers 10 without removing the side cover 1, and also facilitates tightening the bolts 9 securing the shock absorbers 10.

[0044] In this embodiment, the mounting base 4 is welded together by a mounting base plate 41, a mounting top plate 42, and two mounting side plates 43. At least the mounting top plate 42 defines a first mounting hole 12, which is secured to the side cover 1 via a fastener, typically a bolt 11. One end of the anti-disengagement hook 5 is secured to one side of the mounting side plate 43, near the top.

[0045] A second mounting hole (not shown) can be further provided on the mounting base 41, and the second mounting hole is fixedly connected to the side cover 1 via a bolt. Thus, each mounting base 4 can securely connect the side cover 1 to the mounting base 4 at least two fixing points, effectively ensuring the stability of the installed side cover 1. If one of the bolts 11 becomes loose, falls off, or is not tightened properly, the other bolt 11 can still secure the side cover 1, further preventing it from falling off.

[0046] In order to facilitate installation, nuts 13 are pre-embedded in the first mounting hole 12 and the second mounting hole. The side cover 1 and the mounting seat 4 can be fixed together by the cooperation of the bolts 11 and the corresponding nuts 13, which is very convenient for disassembly and assembly.

[0047] In this embodiment, the mounting side plate 43 is preferably a right-angled trapezoidal structure that is narrow at the top and wide at the bottom, with the oblique side facing the side cover 1 and the straight side welded and fixed to the housing side plate 3. This ensures that the mounting base 4 is firmly fixed to the housing side plate 3, thereby improving the overall load-bearing capacity of the mounting base 4.

[0048] In this embodiment, it is further preferred that the cross-section of the mounting base plate 41 is a Z-shaped structure, including a middle horizontal mounting plate 411, an upper mounting plate 412 with an upwardly bent and protruding outer side, and a lower mounting plate 413 with a downwardly bent and protruding inner side. The bottom of the mounting side plate 43 is welded to the horizontal mounting plate 411, the upper mounting plate 412 is placed on the outer side of the mounting side plate 43, the second mounting hole is set on the upper mounting plate 412, and the lower mounting plate 413 and the straight edge of the mounting side plate 43 are on the same plane and are welded to the shell side plate 3 to further increase the welding area between the mounting seat 4 and the shell side plate 3, thereby improving the structural strength of the mounting seat 4.

[0049] In this embodiment, the outer side of the mounting side plate 43 near the bottom is designed to be a straight edge and welded to the upper mounting plate 412 , which helps to further improve the overall structural strength of the mounting base 4 .

[0050] In this embodiment, the area of ​​the horizontal mounting plate 411 is the projected area of ​​the mounting side plate 43 on the horizontal plane, the shock absorber fixing hole 8 is also set on the horizontal mounting plate 411, and a shock absorber fixing hole 8 is set on each side of the mounting side plate 43, and two shock absorbers 10 are installed under each mounting seat 4.

[0051] The present invention also provides an air-conditioning unit, including a shell, in which refrigeration components such as an evaporator, an evaporating fan, a condenser, a condensing fan, and a compressor are installed. A side cover 1 is installed on the outer side of each side of the shell, and the outer sides of the two sides of the shell side plate 3 are respectively installed with the anti-detachment installation structure as described above.

[0052] The anti-detachment installation structure of the side cover of the air-conditioning unit provided by the utility model has the following advantages:

[0053] 1. The utility model utilizes the fixed connection between the mounting base and the side cover, and then utilizes the anti-drop hook to cooperate with the anti-drop hole on the side cover to achieve the anti-drop capability of the side cover. Even if the bolts and other fasteners between the mounting base and the side cover are loose or fall off, or are not tightened properly, it can also ensure that the side cover will not fall off from the mounting base, thereby effectively ensuring the safety of vehicle operation.

[0054] 2. The utility model utilizes the special bending angle of the anti-detachment hook to ensure that the side cover can only be disengaged from the anti-detachment hook when it is manually flipped upward, and will not fall off under non-human operation, and the side cover cannot be removed, thereby ensuring the effectiveness of the cooperation between the side cover and the anti-detachment hook.

[0055] 3. The utility model opens a mounting seat inspection port on the side cover, which is convenient for maintenance personnel to observe the internal installation status without removing the side cover, such as checking whether fasteners such as bolts are loose or falling off. At the same time, the bolts can also be tightened through the mounting seat inspection port to meet the bolt tightening requirements, facilitate daily maintenance operations, and reduce daily workload.

[0056] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
