Detailed Description of the Embodiments
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only 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 embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0031] The core of the present utility model is to provide a sealing structure for the cover plate of an air-conditioning unit of a rail vehicle, and the use of this sealing structure can effectively improve the waterproof performance of the air-conditioning unit. Another core of the present utility model is to provide a vehicle body including the above-mentioned sealing structure for the cover plate of the air-conditioning unit of the rail vehicle.
[0032] Please refer to Figure 1 , the present utility model provides a sealing structure for the cover plate of an air-conditioning unit of a rail vehicle, including a unit housing 1, a cover plate 2, and a sealing strip 3. Among them, the unit housing 1 has an installation cavity 111 for placing the air-conditioning unit, and the top end of the unit housing 1 has a first water retaining edge 121 and a second water retaining edge 122. The first water retaining edge 121 is located on the outer side near the periphery of the unit housing 1, and the second water retaining edge 122 is located inside the first water retaining edge 121; the cover plate 2 is covered on the top of the unit housing 1 and covers the first water retaining edge 121 and the second water retaining edge 122; the sealing strip 3 is installed at the bottom of the cover plate 2, and the second water retaining edge 122 abuts against the sealing strip 3 and is in sealing cooperation with it.
[0033] As Figure 1 and Figure 2 shown, the unit housing 1 is a hollow box structure for placing the air-conditioning unit inside, and there are two layers of annular raised structures, namely the first water retaining edge 121 and the second water retaining edge 122, on the top of the side wall of the unit housing 1. Correspondingly, the cover plate 2 is covered on the top of the unit housing 1 and covers the first water retaining edge 121 and the second water retaining edge 122 below it. The cover plate 2 can adopt a flat plate structure or an arched plate body, etc. Moreover, a sealing strip 3 is clamped between the cover plate 2 and the second water retaining edge 122 of the unit housing 1 to achieve the seal between the cover plate 2 and the unit housing 1, and the first water retaining edge 121 is located outside the second water retaining edge 122 to serve as a water blocking ridge for blocking the flow of liquid. Then, this sealing structure can achieve secondary waterproofing, with excellent sealing performance, which is beneficial to ensuring the normal operation of the air-conditioning unit.
[0034] It should be noted that the number and shape of the sealing strip 3 are not limited, as long as the sealing cooperation between the cover plate 2 and the unit housing 1 can be achieved. For example, in some embodiments, the sealing strip 3 can adopt an annular sealing strip 3, or, in other embodiments, the number of the sealing strips 3 is greater than or equal to two, and several sealing strips 3 are arranged to form an annular structure, etc.
[0035] On the basis of the above embodiments, the unit housing 1 includes a housing body 11 and a support member 12; the housing body 11 has an installation cavity 111; the support member 12 is installed at the top end of the housing body 11, and the support member 12 has a first water retaining edge 121 and a second water retaining edge 122.
[0036] As Figure 1 and Figure 2As shown, the housing body 11 is a hollow thin-shell structure for placing the air-conditioning unit. To install and support the cover plate 2, a support member 12 is installed at the upper end of the housing body 11 by means of riveting or welding. The top of the support member 12 has a first water-blocking edge 121 and a second water-blocking edge 122 protruding upward to reduce the manufacturing difficulty.
[0037] It should be noted that the type of the support member 12 is not limited as long as it can meet the installation requirements. For example, the support member 12 can be an F-shaped bending plate.
[0038] On the basis of the above embodiment, the support member 12 has a water guide plate 123 protruding toward the outside of the housing body 11 to receive and guide the liquid flowing down from the cover plate 2.
[0039] For example, the left top corner of the sealing structure is as Figure 2 As shown, the right side of the support member 12 has a first water-blocking edge 121 and a second water-blocking edge 122 and is blocked under the cover plate 2. The left end of the support member 12 is a water guide plate 123 protruding from the left side of the cover plate 2. The water guide plate 123 and the cover plate 2 above it are arranged in a stepped manner, and the water guide plate 123 is lower than the cover plate 2, so that the liquid flowing down from the left end of the cover plate 2 can be received. Optionally, the water guide plate 123 can adopt a stepped plate structure, and the first order of the support member 12 away from the cover plate 2 is lower than the first order close to the cover plate 2. After the higher order receives the liquid, under the action of gravity, the liquid can flow down smoothly through the free end of the lower order. Or, the water guide plate 123 can adopt an inclined plate structure, and the free end of the water guide plate 123 is the lowest end of itself, which can receive and guide the liquid flowing down from the left end of the cover plate 2.
[0040] It should be noted that the structure of the right top corner of the sealing structure is not limited as long as it can achieve the same function as the above left top corner. Preferably, the support member 12 is a symmetric structure to further reduce the manufacturing difficulty.
[0041] On the basis of the above embodiment, the support member 12 is a hollow profile. The support member 12 has a first cavity 124 and a second cavity 125. The first cavity 124 is located on the outer side near the periphery of the support member 12, and the second cavity 125 is located inside the first cavity 124. The first water-blocking edge 121 extends vertically and intersects the cavity wall between the first cavity 124 and the second cavity 125.
[0042] As Figure 1 and Figure 2As shown, the support member 12 has a first cavity 124 and a second cavity 125 in the shape of a trapezoid and / or a rectangle, and the first cavity 124 and the second cavity 125 are arranged side by side. The first water retaining edge 121 extends vertically, and the bottom of the first water retaining edge 121 is connected to the cavity wall between the first cavity 124 and the second cavity 125. Such a setting is beneficial to improving the anti-deformation ability of the support member 12 while reducing the weight of the sealing structure.
[0043] On the basis of the above embodiment, it further includes a mounting base 4; the mounting base 4 has a mounting hole for inserting a fastener 5 to fixedly connect the support member 12 and the mounting base 4, and the mounting base 4 and the cover plate 2.
[0044] As Figure 1 and Figure 2 shown, the support member 12 and the cover plate 2 are assembled through the mounting base 4, that is, a mounting hole is provided on the mounting base 4. Correspondingly, through holes are provided on both the cover plate 2 and the support member 12. After the cover plate 2, the mounting base 4 and the support member 12 are assembled, the through holes on the cover plate 2 and the support member 12 and the corresponding mounting holes on the mounting base 4 extend with a common diameter. Then, several fasteners 5 can pass through the corresponding and co-diameter through holes and mounting holes above to fixedly connect the support member 12 and the mounting base 4, and the mounting base 4 and the cover plate 2. Such a setting makes the structures of the cover plate 2 and the unit housing 1 in the sealing structure simple, facilitating reducing the manufacturing and assembly difficulty and cost while ensuring the waterproof performance.
[0045] It should be noted that the type of the mounting base 4 is not limited, as long as the above functions can be achieved. For example, an angle iron can be used.
[0046] On the basis of the above embodiment, the bottom of the cover plate 2 has a third water retaining edge 21, and the third water retaining edge 21 is located outside the first water retaining edge 121.
[0047] As Figure 1 and Figure 2 shown, a hem is provided around the cover plate 2 as the third water retaining edge 21, or a ring-like protruding structure is provided below the cover plate 2 as the third water retaining edge 21. After the cover plate 2 is covered on the unit housing 1, the third water retaining edge 21 is located outside the first water retaining edge 121. Then, the third water retaining edge 21, the first water retaining edge 121 and the second water retaining edge 122 are arranged in sequence from inside to outside. Such a setting is beneficial to further improving the waterproof effect.
[0048] On the basis of the above embodiment, the mounting base 4 is a profile member with an F-shaped cross-section and is inverted. The top plate of the mounting base 4 fits against the bottom surface of the cover plate 2, the first side plate of the mounting base 4 fits against the inner surface of the third water retaining edge 21, and the second side plate of the mounting base 4 fits against the inner surface of the first water retaining edge 121.
[0049] As Figure 1 and Figure 2 shown, the mounting base 4 is arranged between the cover plate 2 and the support member 12 and placed horizontally. The horizontal plate above the mounting base 4 is in contact with the bottom surface of the cover plate 2, and the vertical plate on the left side of the mounting base 4 is in contact with the inner side surface of the third water retaining edge 21. The vertical plate on the right side of the mounting base 4 is in contact with the inner or outer side surface of the first water retaining edge 121. With such an arrangement, it is convenient to position the mounting base 4 and to connect the cover plate 2 and the support member 12 through the fastener 5.
[0050] Based on the above embodiment, the bottom of the first water retaining edge 121 has a drain hole. As Figure 1 and Figure 2 shown, a through hole such as a circular or square hole is opened at the bottom end of the first water retaining edge 121 as the drain hole, so as to drain the accumulated liquid in the cavity between the first water retaining edge 121 and the second water retaining edge 122 while ensuring the waterproof performance of the first water retaining edge 121.
[0051] It should be noted that the number and position of the drain holes are not limited, as long as the drainage function can be achieved. For example, in some embodiments, the number of drain holes is four, and corresponding drain holes are respectively opened at the four top corner positions of the rectangular ring-shaped first water retaining edge 121. Or, in other embodiments, corresponding drain holes are respectively opened at the middle positions of the left side and the right side of the rectangular ring-shaped first water retaining edge 121, etc.
[0052] Based on the above embodiment, the bottom of the cover plate 2 has a mounting protrusion 22, and the mounting protrusion 22 has a receiving groove, and the sealing strip 3 is embedded in the interior of the receiving groove.
[0053] As Figure 1 and Figure 2 shown, a ring-shaped block-shaped receiving protrusion is arranged at the bottom of the cover plate 2 by welding or integrally forming, etc., and a ring-shaped receiving groove is opened at the lower end of the receiving protrusion, so that the sealing strip 3 is nested inside it. With such an arrangement, it is convenient to replace the sealing strip 3 to ensure the waterproof performance of the sealing structure.
[0054] Based on the above embodiment, the second water retaining edge 122 is a bent structure, the bottom end of the second water retaining edge 122 extends vertically, and the top end extends horizontally.
[0055] As Figure 2 shown, the second water retaining edge 122 is an L-shaped bent structure, its bottom end extends vertically, and its top end extends horizontally to tightly abut against the sealing strip 3. With such an arrangement, it is beneficial to prevent the deformation of the sealing strip 3 while ensuring the waterproof performance.
[0056] In addition to the above sealing structure for the cover plate of the rail vehicle air conditioner unit, the present utility model further provides a vehicle body including the sealing structure for the cover plate of the rail vehicle air conditioner unit disclosed in the above embodiments.
