Description

Technical Field

[0001] This invention belongs to the field of EMU interior structure, and particularly relates to an installation structure and process for the air outlet profile of the lower part of the side wall of an EMU. Background Technology

[0002] like Figures 1 to 3 As shown, the upper part of the existing EMU side wall lower air outlet profile 5 is connected to the side wall panel 3, and the lower part is connected to the floor 4. As a transition structure between the floor and the side wall panel, it is installed in sections along the length of the vehicle. Both ends are connected to the inner end partitions (one inner end partition 1 and two inner end partitions 2). The length between the two inner end partitions is generally about 20 meters. The air outlet profile 5 needs to be installed in multiple sections.

[0003] There is a process error in the length between the inner walls at both ends, which means that the design of the air outlet profile needs to leave a process allowance. The theoretical length of the joint exceeds the length between the two inner walls. During installation, it is necessary to cut the material according to the actual length between the two inner walls. The installation is extremely time-consuming and the length and straightness of the material cut are difficult to control. Gaps or unevenness will appear at the joint, resulting in poor performance. Summary of the Invention

[0004] To address the problems in related technologies, this invention proposes an installation structure for the air outlet profile at the lower part of the side wall of a high-speed train, which can comprehensively solve the above problems. The installation method of this invention is convenient and aesthetically pleasing. This structure has high adaptability, reduces on-site process adjustments and cutting time, improves appearance quality, and reduces costs.

[0005] Therefore, the specific technical solution adopted by the present invention is as follows: A mounting structure for the lower air outlet profile of the side wall of a high-speed train includes several air outlet profiles arranged longitudinally between the floor and the side wall panel. The structure is characterized by: a gap being formed between adjacent air outlet profiles; a groove being provided at the top of the air outlet profile near the gap; and several vertically arranged insertion holes being provided on one side of the air outlet profile near the gap. The mounting structure also includes an upper cover plate and a lower cover plate for covering the gap. The upper cover plate has an upper cover plate panel and an insertion plate located on the back. The upper cover plate is inserted from above the gap so that the insertion plate is embedded in the groove. The upper cover plate panel and the insertion plate are located on the outer and inner sides of the air outlet profile, respectively. The lower cover plate has a lower cover plate panel and two rows of vertically arranged elastic clips suitable for engaging the insertion holes. When the elastic clips are engaged in the insertion holes one by one, the lower cover plate panel covers the gap at the corresponding position.

[0006] Furthermore, the top of the upper cover plate also has an upper cover plate hook, which hooks onto the top edge of the air outlet profile.

[0007] Furthermore, the bottom of the lower cover plate also has a lower cover plate hook, which hooks onto the bottom edge of the air outlet profile.

[0008] Furthermore, the longitudinal spacing between the groove bottoms of adjacent air outlet profiles is greater than the width of the insert plate, allowing for longitudinal adjustment of the upper cover. The width of the insertion hole is between the maximum width of the elastic clip and the waist width, allowing for longitudinal adjustment of the lower cover.

[0009] This invention also proposes an installation process for the air outlet profile at the lower part of the side wall of a high-speed train, characterized by being based on the aforementioned installation structure for the air outlet profile at the lower part of the side wall of the high-speed train, specifically including the following steps: Step 1: Pre-process the air outlet profile. The top of the air outlet profile has a groove on one side near the splice, and several vertically arranged insertion holes are provided on the side of the air outlet profile near the splice. Step 2: Install the air outlet profiles on the vehicle, connecting the top and bottom ends to the side wall panels and floor respectively. The air outlet profiles are arranged longitudinally with a gap between adjacent air outlet profiles. Step 3: Insert the top cover plate from the top of the air vent profile, so that the insert plate of the top cover plate is embedded in the groove and the top of the air vent profile is hung by the hook of the top cover plate. After the top cover plate is installed, the top cover plate panel will cover the gap at this point. Step 4: Place the lower cover plate in the gap, hook the hook of the lower cover plate onto the bottom edge of the air vent profile and press the lower cover plate so that the elastic clips are inserted into the corresponding holes. After the lower cover plate is installed, the lower cover plate panel will cover the gap at this point.

[0010] Furthermore, this invention also claims protection for an interior structure of a rail vehicle, including a first inner end partition wall, a second inner end partition wall, a floor and a side wall panel located between the first inner end partition wall and the second inner end partition wall, wherein a plurality of air outlet profiles are longitudinally arranged between the floor and the side wall panel, characterized in that: it also includes the aforementioned air outlet profile installation structure at the lower part of the side wall of the EMU.

[0011] This invention reserves a process installation allowance gap between two sections of air outlet profiles. A cover plate is designed to cover the gap. The cover plate is divided into upper and lower sections. The upper cover plate adopts a plug-in type and can be adjusted left and right. The lower cover plate has an elastic snap-fit ​​structure. The air outlet profile has an insertion hole. During installation, the elastic snap of the lower cover plate is inserted into the insertion hole on the air outlet profile. A gap is left between the insertion hole and the elastic snap in the width direction. While ensuring that the lower cover plate is firmly snapped in place, it can also be adjusted left and right according to the gap at the joint of the air outlet profiles. This improves the appearance quality of the joint of the air outlet profiles and eliminates the need to cut air outlet parts from the vehicle, thus improving installation efficiency.

Detailed Implementation

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] like Figures 4-13 As shown, the air outlet profile installation structure of the lower part of the side wall of the EMU in this embodiment of the invention includes a plurality of air outlet profiles 5 arranged longitudinally between the floor 4 and the side wall panel 3, an upper cover plate 7 and a lower cover plate 8.

[0029] A gap 6 is formed between adjacent air outlet profiles 5. A groove 51 is provided on the top of the air outlet profile 5 near the gap 6. Several vertically arranged insertion holes 9 are provided on one side of the air outlet profile 5 near the gap 6. The upper cover plate 7 and the lower cover plate 8 are used to cover the upper and lower middle parts of the gap 6, respectively.

[0030] like Figures 6 to 9 As shown, the upper cover 7 has an upper cover panel 71, an insert plate 73 located at the back, and an upper cover hook 72 at the top. The upper cover panel 71 and the insert plate 73 are connected by a vertical connecting strip 74. The insert plate 73 is used to embed into the groove 51 from above the air outlet profile 5; the upper cover hook 72 is used to hook onto the top edge of the air outlet profile 5. After the upper cover 7 is installed, the upper cover panel 71 and the insert plate 73 are located on the outer and inner sides of the air outlet profile 5, respectively, and the gap 6 at this location is covered by the upper cover panel 71. In this embodiment, the longitudinal distance between the bottom of the grooves 51 of adjacent air outlet profiles 5 is greater than the width of the insert plate 73, so that the upper cover 7 has longitudinal adjustment space. Furthermore, the upper cover panel 71 and the insert plate 73 are connected by a vertical connecting strip 74. The width of the vertical connecting strip 74 is less than the width of the gap 6. The difference between the width of the gap 6 and the width of the vertical connecting strip 74 is not less than the difference between the longitudinal spacing of the groove bottom of the adjacent air outlet profile 5 and the width of the insert plate 73, ensuring that the longitudinal adjustment of the upper cover 7 will not be interfered with by the vertical connecting strip 74.

[0031] like Figures 10 to 13 As shown, the lower cover plate 8 has a lower cover plate panel 81, a lower cover plate hook 83 at the bottom, and two rows of vertically arranged elastic clips 82 on the back. The lower cover plate hook 83 is used to hook the bottom edge of the air outlet profile 5 to fix the bottom of the lower cover plate 8 and prevent it from tilting up; the two rows of vertically arranged elastic clips 82 are adapted to be inserted into the corresponding insertion holes 9. When all the elastic clips are inserted into the insertion holes 9, the lower cover plate panel 81 covers the gap 6 at the corresponding position. In this embodiment, the width of the insertion hole 9 is between the maximum width of the elastic clip 81 and the waist width, so that the lower cover plate 8 has longitudinal adjustment space.

[0032] The installation process of the air outlet profile at the lower part of the side wall of the EMU in this embodiment includes the following steps: Step 1: Pre-process the air outlet profile 5. The top of the air outlet profile 5 is provided with a groove 51 on the side near the splice. Several vertically arranged holes 9 are provided on the side of the air outlet profile 5 near the splice.

[0033] Step 2: Install the air outlet profile 5 on the vehicle. The upper and lower ends are respectively connected to the side wall panel 3 and the floor. The air outlet profile 5 is arranged longitudinally and a gap 6 is reserved between adjacent air outlet profiles 5.

[0034] Step 3: Insert the top cover plate 7 from the top of the air outlet profile 5, so that the insert plate 73 of the top cover plate 7 is embedded in the groove 51 and hooked onto the top of the air outlet profile 5 by the top cover plate hook 72. After the top cover plate 7 is installed, the top cover plate panel 71 covers the gap 6. This step also includes the step of adjusting the top cover plate 7 vertically. Specifically, apply a force to the left or right to the top cover plate 7 to make the insert plate 73 slide in the groove 51, thereby realizing the left and right adjustment of the top cover plate 7 to better cover the gap 6.

[0035] Step 4: Place the lower cover plate 8 at the gap 6. Hook the lower cover plate hook 83 onto the bottom edge of the air outlet profile 5 and press the lower cover plate 8 down so that the elastic clips 81 are inserted into the corresponding holes 9. After the lower cover plate 8 is installed, the lower cover plate panel 81 covers the gap 6. This step also includes a longitudinal adjustment of the lower cover plate 8. Specifically, apply a force to the left or right to the lower cover plate 8 so that the elastic clips 81 slide within the holes 9, thereby achieving left and right adjustment of the lower cover plate 8 to better cover the gap 6.

[0036] like Figures 4 to 5 As shown, this embodiment also relates to an interior structure of a rail vehicle, including a first inner end partition 1, a second inner end partition 2, a floor 4 and a side wall panel 3 located between the first inner end partition 1 and the second inner end partition 2, and a plurality of air outlet profiles 5 arranged longitudinally between the floor 4 and the side wall panel 3. The interior structure also includes the air outlet profile installation structure of the lower part of the EMU side wall of the above embodiment.

[0037] This invention reserves a manufacturing allowance gap between two air outlet components. A cover plate is designed to cover the gap. The cover plate is divided into upper and lower sections. The upper cover plate adopts a plug-in type and can be adjusted left and right. The lower cover plate has an elastic snap-fit ​​structure. A rectangular hole is opened on the air outlet profile. During installation, the elastic snap-fit ​​on the cover plate is inserted into the rectangular hole on the air outlet profile. A gap is left between the rectangular hole and the elastic snap-fit ​​in the length direction. While ensuring that the cover plate is firmly snapped, it can also be adjusted left and right according to the gap at the joint of the air outlet profile. This improves the appearance quality of the joint of the air outlet profile and eliminates the need to cut air outlet components from the vehicle, thus improving installation efficiency.

[0038] The present invention features a convenient and aesthetically pleasing installation method. Its structure is highly adaptable, reducing on-site process adjustments and cutting time, improving appearance quality, and lowering costs.
