[0002] Traditional car window sunshades are usually set on the surface of the car window facing the inside of the vehicle, which makes the entire car window thicker and the user's comfort and convenience worse. For vehicle doors, the increase in the thickness of the car window will further increase the thickness of the vehicle door, and the thickness of the vehicle door will affect the opening and closing method of the vehicle door and the vehicle. Therefore, traditional car window sunshades are more suitable for folding doors, but will affect the normal door function of sliding plug doors, external doors or internal doors. However, the performance advantage of folding doors is currently not as good as that of sliding plug doors, external doors or internal doors. Therefore, in order to improve the performance of vehicle doors, it is particularly important to improve the car window sunshades. Utility Model Content

DETAILED DESCRIPTION
[0031] First, let me introduce the application scenario of this application: the vehicle doors of rail transit vehicles, especially the driver's cab doors, are usually structures with both sunshades and sliding windows, and are all manual folding doors. The sliding window structure is usually designed with inner and outer window frames, for example, Figure 1 As shown, the inner window frame 1 is installed with a fixed glass 2, and the outer window frame 3 is installed with a sliding glass 4. The sliding glass 4 can slide up and down relative to the fixed glass 2. The sliding glass 4 is also provided with a handle 5 for moving the sliding glass 4. The handle 5 is located on the inner side of the sliding glass 4 facing the vehicle. In order to reduce the size in the thickness direction, the handle 5 usually does not protrude from the inner side of the inner window frame 1 facing the vehicle. It can be seen that the thickness of the vehicle window is increased due to the design of the inner and outer window frames. Figure 2 , the sunshade 6 is arranged on the surface of the door leaf facing the inner side of the vehicle, further increasing the thickness of the door. For example, the sunshade usually protrudes more than 40mm from the surface of the door leaf. Therefore, this type of sunshade will seriously affect the normal door function of the sliding plug door, the external door or the built-in door, thus greatly limiting the optional space of the driver's cab door system. At present, the sliding plug door is superior to the manual folding door in terms of convenience and reliability. At the same time, the sunshade and sliding window in the driver's cab provide the necessary convenience for the driver to check the vehicle and platform conditions. In summary, it is very necessary to develop a window device with a built-in sunshade and a sliding window.
[0032] Based on the above application scenarios, the embodiments of the present application provide a door and window device, a vehicle door of a rail vehicle and a rail vehicle, which are used to partially embed the sunshade into the door leaf to reduce the overall thickness of the door and window device, thereby not affecting the normal door function of the sliding Sierra door, the external door or the internal door.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.
[0035] The present invention provides a vehicle door for a rail vehicle, comprising a door leaf and a door and window device, wherein the door and window device is embedded in the door leaf. Figure 3 As shown, the door leaf includes an inner door skin 610 and an outer door skin 620. The door and window device penetrates the inner door skin 610 and the outer door skin 620 and is embedded in the door leaf. It should be noted that there is also a filling material between the inner door skin 610 and the outer door skin 620. Figure 3 The thickness direction of the door and window device can be understood as the arrangement direction of the inner door skin 610 and the outer door skin 620.
[0036] Reference Figures 3 to 5 The door and window device provided by the embodiment of the utility model includes: a window frame 100 and a sunshade mechanism, the window frame 100 includes a first outer surface and a second outer surface arranged along a first direction, the first direction is perpendicular to the thickness direction of the window frame 100; the sunshade mechanism includes a fixing member 210 and a sunshade curtain assembly; the fixing member 210 is fixed on the first outer surface, and the first direction is perpendicular to the thickness direction of the window frame 100; the sunshade curtain assembly includes a reel 221, a curtain 222 and a pull shaft 223; the reel 221 is rotatably installed inside the fixing member 210, and the fixing member 210 has a first opening to avoid the curtain 222; the curtain 222 extends from the first opening along the first direction to the outside of the fixing member 210 and is connected to the pull shaft 223; along the first direction, the reel 221 and the window frame 100 have an overlapping area.
[0037] The above-mentioned door and window device includes a window frame 100 and a sunshade mechanism, wherein the window frame 100 includes a first outer surface and a second outer surface, and the first outer surface and the second outer surface are arranged along a first direction, that is, perpendicular to the thickness direction of the window frame 100; the sunshade mechanism includes a fixing member 210 and a sunshade curtain assembly, and the sunshade curtain assembly is fixedly installed by the fixing member 210. Along the first direction, that is, perpendicular to the thickness direction of the window frame 100, the fixing member 210 is fixed to the first outer surface of the window frame 100, that is, the fixing member 210 and the window frame 100 are arranged along the first direction; the sunshade assembly includes a reel 221, a curtain 222 and a pull shaft 223, the reel 221 is rotatably installed inside the fixing member 210, the pull shaft 223 is located outside the fixing member 210, the curtain 222 connects the reel 221 and the pull shaft 223, and the fixing member 210 has a first opening for avoiding the curtain 222, the reel 221 rotates to wind or release the curtain 222 to drive the curtain 222 and the pull shaft 223 to rise and fall along the first direction, so as to ensure the function of the sunshade assembly is realized. Further, along the first direction, the reel 221 and the window frame 100 have an overlapping area, that is, the sunshade assembly fully utilizes the space in the first direction and reduces the size of the window frame 100 in the thickness direction. When the door and window device is installed in a door leaf, the fixing part 210 and the reel 221 are hidden inside the door leaf, which reduces the size of the door leaf in the thickness direction, thereby facilitating the door leaf to be suitable for rail vehicles with sliding doors, external doors or internal doors.
[0038] One possible implementation method is Figure 3-Figure 5 As shown, the first outer surface and the second outer surface of the window frame 100 are along Figure 3 The Z direction is the longitudinal direction of the door and window device; the fixing member 210 and the window frame 100 are arranged along Figure 3 The arrangement in the Z direction can be understood as the fixing member 210 being located above the window frame 100. The fixing member 210 has a sunshade installation groove inside, such as Figure 3 As shown, the fixing member 210 has a first side wall and a second side wall arranged along the thickness direction of the window frame 100, and a third side wall and a fourth side wall arranged along the first direction. The second side wall, the third side wall, the first side wall and the fourth side wall are sequentially connected to form the installation groove. It can be understood that the fixing member 210 is a square tube structure, and the two ends are respectively rotatably connected to the two ends of the reel 221. In order to show the reel 221 inside the fixing member 210, Figure 3The end of the fixing member 210 is not shown in the figure. The first opening is arranged at a corner of the square tube, and the first opening extends along the length direction of the square tube. The first opening is arranged at a corner of the square tube, which can be understood as the second side wall of the fixing member 210 having a first notch, and the fourth side wall having a second notch, and the first notch and the second notch constitute the first opening. The reel 221 can be loaded into the fixing member 210 from the first opening. The curtain 222 in the sunshade curtain assembly is raised and lowered along the Z direction, and the curtain 222 can be flattened in the direction of gravity of the pull shaft 223, that is, the Z direction, so that the curtain 222 can partially cover or fully cover the glass on the door and window device. In order to ensure that the curtain 222 is subjected to balanced force, the axial direction of the reel 221 is approximately horizontal, the axial direction of the pull shaft 223 is approximately horizontal, and accordingly, the axial direction of the fixing member 210 can also be approximately horizontal.
[0039] It can be understood that the first direction can also be the lateral direction of the door and window device. At this time, the arrangement of the fixing member 210 and the window frame 100 along the first direction can be understood as the fixing member 210 being located on the left or right side of the window frame 100. Due to the influence of gravity, the curtain 222 cannot be flattened when the pull shaft 223 is free. Therefore, in this case, the pull shaft 223 and the winding shaft 221 need to cooperate to pull the curtain 222 flat. Therefore, the fixed position of the pull shaft 223 needs to be set to achieve partial or full coverage of the glass on the door and window device by the curtain 222.
[0040] In some embodiments, the sunshade mechanism further includes a cover plate 230; the cover plate 230 is fixed to the fixing member 210 and covers the portion of the first opening in the thickness direction of the window frame 100. The cover plate 230 is an appearance component to ensure that the internal structure is not exposed and remains removable and maintainable.
[0041] It can be understood that the roller 221 of the sunshade curtain assembly can be installed into the fixing member 210 from the first opening of the fixing member 210. In order to protect the roller 221 part of the sunshade curtain assembly, the first notch of the first opening is covered by the cover plate 230, thereby preventing the roller 221 from escaping from the fixing member 210 from the first opening while ensuring a beautiful appearance.
[0042] In some embodiments, in order to facilitate the installation and transportation of the sunshade curtain assembly, the sunshade curtain assembly also includes a cover plate 224; the cover plate 224 is sleeved on the outside of the roller 221 and fixed inside the fixing member 210 through the cover plate 230; the cover plate 224 has a second opening for avoiding the curtain cloth 222.
[0043] One possible implementation method is Figure 3As shown, the cover plate 224 is fixed to the side wall of the fixing member 210 facing the inner side of the vehicle, that is, the second side wall, through the cover plate 230. Similarly, the cover plate 224 is provided with a second opening to facilitate the installation of the reel 221 and the curtain 222 into the cover plate 224. The size of the second opening is smaller than that of the first opening. The size of the first opening also needs to take into account the outer dimensions of the cover plate 224, so that the cover plate 224 and the reel 221 can be installed into the installation groove inside the fixing member 210. Figure 3 As shown, the cover plate 230 is connected to the second side wall of the fixing member 210 through the first fastener 231. For example, a connecting nut is riveted on the second side wall. The first fastener 231 sequentially penetrates the cover plate 230 and the inner door skin 610 and is threadedly connected to the nut on the second side wall. The cover plate 230 is also connected to the second side wall of the fixing member 210 through the second fastener 232. For example, a connecting nut is riveted on the side plate of the second side wall. The second fastener 232 penetrates the cover plate 230, the cover plate 224, the inner door skin 610 and is threadedly connected to the nut on the second side wall.
[0044] In some embodiments, in order to avoid collision between the curtain 222 and the pull shaft 223 due to vibration or wind force during use of the sunshade curtain assembly, the door and window device also includes a guide mechanism, which includes a guide rod 310 fixed to the window frame 100 on the side close to the interior of the vehicle; the guide rod 310 extends along a first direction; the pull shaft 223 is sleeved on the outside of the guide rod 310 and is slidably connected to the guide rod 310; when there are at least two guide rods 310, there are two guide rods 310 symmetrically arranged at both ends of the pull shaft 223.
[0045] One possible way to achieve this is as follows: Figure 4 and Figure 5 As shown, the guide rod 310 extends in the first direction, i.e., the Z direction, and the end of the pull shaft 223 is sleeved outside the guide rod 310 and slidably connected to the guide rod 310 to guide the lifting movement of the pull shaft 223. In order to ensure that the pull shaft 223 is not skewed, the symmetrically arranged guide rods 310 are used for guidance. At the same time, in order to prevent the guide rods 310 from blocking the line of sight, the guide rods 310 are arranged at both ends of the pull shaft 223.
[0046] In some embodiments, the window frame 100 includes an inner window frame 110 and an outer window frame 120, and the inner window frame 110 and the outer window frame 120 are detachably connected; the inner window frame 110 includes a first mounting surface 111 and a second mounting surface 112 that are vertically connected, and the second mounting surface 112 is perpendicular to the first direction and is located on the side of the inner window frame 110 close to the second outer surface; the first end of the guide rod 310 is installed on the first mounting surface 111 through the first fixing seat 320, and the second end is installed on the second mounting surface 112 through the second fixing seat 330.
[0047] One possible way to achieve this is as follows: Figure 4-Figure 9As shown, the window frame 100 includes an inner window frame 110 and an outer window frame 120. The inner window frame 110 can be understood as the window frame 100 of the door and window device facing the inside of the vehicle, and the outer window frame 120 can be understood as the window frame 100 of the door and window device facing the outside of the vehicle. A fixed glass 500 is installed on the inner window frame 110, and a sliding glass 400 is installed on the outer window frame 120. The sliding glass 400 can slide up and down along the Z direction, and a window handle 410 is installed on the sliding glass 400 for easy operation, as shown in FIG. Figure 5 The two window handles 410 are symmetrically arranged on both sides of the sliding glass 400, so that the sliding glass 400 is subjected to balanced force during operation. Figure 7 A wear-resistant strip 420 is provided between the inner window frame 110 and the outer window frame 120. The wear-resistant strip 420 is made of wear-resistant material. The wear-resistant strip 420 has a plurality of slots spaced along a first direction on one side facing the window handle 410. The slots can be engaged with the locking tongue on the window handle 410 to achieve height adjustment of the sliding glass 400.
[0048] Reference Figure 6 In the Z direction, the reel 221 and the inner window frame 110 have an overlapping area, that is, the sunshade assembly makes full use of the space in the Z direction and reduces the size of the window frame 100 in the thickness direction. The fixing member 210 is located between the inner door skin 610 and the outer door skin 620, that is, the fixing member 210 and the reel 221 are hidden inside the door leaf, reducing the size of the door leaf in the thickness direction, so that the door leaf is suitable for rail vehicles with plug sliding doors, external hanging doors or internal doors.
[0049] The inner window frame 110 and the outer window frame 120 are detachably connected, for example, the inner window frame 110 and the outer window frame 120 are connected by bolts, and the two parts are separate parts, so that the inner window frame 110 and the outer window frame 120 can adopt different structures. The inner window frame 110 is used to install the fixed glass 500 and the guide rod 310. The outer window frame 120 is used to install the movable window glass. The outer window frame 120 can select a right angle or a rounded corner structure at the four corners according to the appearance requirements of the vehicle. Figure 4 As shown, the inner window frame 110 adopts a right-angle structure design, which is convenient for installing the guide rod 310. Specifically, the inner window frame 110 includes a first mounting surface 111 and a second mounting surface 112 that are vertically connected, the first mounting surface 111 is located at the left part or the right part of the inner window frame 110, and the second mounting surface 112 is perpendicular to the first direction and is located on the side of the inner window frame 110 close to the second outer surface, that is, the second mounting surface 112 is located at the lower part of the inner window frame 110; the first end, i.e., the upper end, of the guide rod 310 is mounted on the first mounting surface 111 through the first fixing seat 320, and the second end, i.e., the lower end, is mounted on the second mounting surface 112 through the second fixing seat 330.
[0050] In some embodiments, along the thickness direction of the window frame 100 , there is a gap between the pull shaft 223 and the window frame 100 .
[0051] like Figure 6 As shown, in order to prevent the pull shaft 223 and the window frame 100 from being worn during the lifting process of the curtain 222, a gap L is provided between the pull shaft 223 and the inner window frame 110 along the thickness direction of the window frame 100, thereby extending the service life of the sunshade. It should be noted that the gap will increase the thickness of the entire door and window device, so it should not be too large.
[0052] In one possible implementation, the curtain 222 can be retracted by pulling the pull shaft 223 downward and releasing it instantly. After the curtain 222 is retracted, it is attached to the reel 221 and stored in the cover plate 224. The cover plate 230 and the cover plate 224 are fastened to the fixing member 210 in sequence by the second fastener 232. The cover plate 230 is fastened to the fixing member 210 by the first fastener 231. The cover plate 230 is used as an appearance part to ensure that the internal structure is not exposed and to maintain detachable and maintainability. When the pull shaft 223 is pulled downward, the curtain 222 can cover the car door window and ensure that the curtain 222 and the pull shaft 223 do not interfere with the window handle 410. The entire sunshade mechanism is hidden inside the door leaf. The first fastener 231 is the highest part protruding from the inner door skin 610 and does not affect the door leaf plug pull.
[0053] In some embodiments, a buffer member 340 is disposed between the first fixing seat 320 and the pull shaft 223 to prevent the pull shaft 223 from colliding with the first fixing seat 320 when the pull shaft 223 rises to a maximum height. For example, the buffer member 340 may be a rubber member.
[0054] One possible way to achieve this is as follows: Figure 7 As shown, the buffer member 340 is sleeved on the outside of the guide rod 310 , and the buffer member 340 and the guide rod 310 can be interference fitted, that is, the buffer member 340 is always in contact with the first fixing seat 320 , so as to buffer the force of the pull shaft 223 .
[0055] In some embodiments, the first fixing seat 320 is an L-shaped structure, including a first fixing portion 321 and a second fixing portion 322, the first fixing portion 321 is fixed to the first mounting surface 111, and the second fixing portion 322 is detachably connected to the guide rod 310;
[0056] And / or, the second fixing seat 330 is an L-shaped structure, including a third fixing portion 331 and a fourth fixing portion 332 , the third fixing portion 331 is fixed to the second mounting surface 112 , and the fourth fixing portion 332 is detachably connected to the guide rod 310 .
[0057] In one possible implementation, since the reel 221 is located above the inner window frame 110, the upper side wall of the inner window frame 110 needs to avoid the curtain 222, that is, the upper side wall of the inner window frame 110 cannot be used as a mounting member for the guide rod. Figure 6 and Figure 7As shown, the left side wall and the right side wall of the inner window frame 110 are used as mounting parts of the guide rod, for example, the right side wall of the inner window frame 110 is connected to the upper end of the guide rod by an L-shaped structural member with an opening toward the left side wall. Specifically, the first fixing seat 320 includes a first fixing portion 321 and a second fixing portion 322, the first fixing portion 321 is detachably connected to the first mounting surface 111 located on the left side wall or the right side wall of the inner window frame 110, and the second fixing portion 322 is detachably connected to the guide rod 310. Exemplarily, the first fixing portion 321 is connected to the inner window frame 110 through a third fastener 323, such as a connecting nut riveted on the inner window frame 110, and the third fastener 323 passes through the first fixing portion 321 and is threadedly connected to the connecting nut on the inner window frame 110.
[0058] One possible way to achieve this is as follows: Figure 8 and Fig. 9 As shown, the bottom wall of the inner window frame 110 is connected to the lower end of the guide rod by an L-shaped structural member with an opening toward the left side wall. Specifically, the second fixing seat 330 includes a third fixing portion 331 and a fourth fixing portion 332, the third fixing portion 331 is detachably connected to the second mounting surface 112 located on the bottom wall of the inner window frame 110, and the fourth fixing portion 332 is detachably connected to the guide rod 310. Exemplarily, the third fixing portion 331 is connected to the inner window frame 110 by a fourth fastener 333, such as a connecting nut riveted on the inner window frame 110, and the fourth fastener 333 penetrates the third fixing portion 331 and is threadedly connected to the connecting nut on the inner window frame 110. The first fixing seat 320 and the second fixing seat 330 adopt the same structure to save manufacturing costs while conveniently ensuring the directionality of the guide rod 310.
[0059] For example, when the guide rod 310 is installed, the two ends of the guide rod 310 can be connected to the first fixing seat 320 and the second fixing seat 330 respectively, and then the first fixing seat 320 and the second fixing seat 330 are fixed to the corresponding installation surfaces in sequence.
[0060] In some embodiments, the guide rod 310 is threadedly connected to the second fixing portion 322 and / or the fourth fixing portion 332. External threads are provided at both ends of the guide rod 310, and the second fixing portion 322 and / or the fourth fixing portion 332 are provided with internal threads that match the external threads on the guide rod 310, so that the guide rod 310 is conveniently connected to the first fixing seat 320 and the second fixing seat 330 without the need for additional connectors, and the structure is simple and easy to install.
[0061] In a possible implementation, both ends of the pull shaft 223 are sleeved in the guide rod 310, and a buffer 340 such as a rubber buffer sleeve is installed between the pull shaft 223 and the upper first fixing seat 320 to play a buffering role. The upper first fixing seat 320 is installed on the inner window frame 110 through the third fastener 323, and the lower second guide rod fixing seat is installed on the inner window frame 110 through the fourth fastener 333. The upper first fixing seat 320 and the lower second fixing seat 330 are both symmetrical, with a total of 4 locations. Both ends of the guide rod 310 have external threads, which are connected to the first fixing seat 320 and the second fixing seat 330 through the internal threads on the upper first fixing seat 320 and the lower second fixing seat 330 respectively.
[0062] The pull shaft 223 is pulled and moves up and down along the guide rod 310. The third fastener 323, the first fixing seat 320, the buffer 340, the guide rod 310, and the second fixing seat 330 do not protrude from the inner door skin 610, and ensure that when the pull shaft 223 is pulled downward, it will not interfere with the window handle 410.
[0063] In summary, the door and window device provided in the embodiment of the utility model allows the sunshade to be hidden inside the vehicle door, which adds more space for the selection of vehicle doors of rail vehicles such as the driver's cab door system. The door and window device greatly reduces the space occupied by traditional sunshades in the thickness direction of the door leaf, and is suitable for most current door system types.
[0064] On the other hand, an embodiment of the utility model further provides a rail vehicle, comprising the vehicle door of the rail vehicle described above.
