[0058] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0059] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0060] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0061] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0062] Some related seats suffer from a loose fit between the outer shell and the cover, which results in poor back support for passengers and reduced riding comfort. Furthermore, foreign matter can easily enter the gap between the outer shell and the cover, compromising rail vehicle hygiene and safety. Other related seats also suffer from the difficulty of separating the outer shell and the cover, hindering replacement. To address this issue, the present disclosure provides a seat in which the cover and outer shell fit snugly and can be easily separated.

[0063] The backrest of the seat includes a cover, a cover and an adjustment part. The cover includes a first part and a second part, and a plurality of buckles are provided on the peripheral sides of the first part and the second part. The cover is provided with a plurality of slots, and a connecting ring is provided in each slot. The adjustment part includes an adjustment rope and a control component. The adjustment rope is arranged around the outer edge of the bottom of the plurality of buckles. The control component is provided between the first part and the second part, and extends from the inside of the cover to the outside of the cover. The end of the adjustment rope is movably connected to the control component. By operating the control component to move the adjustment rope, the adjustment rope tightens or loosens the bottom of the buckle, and the top of the buckle tilts outward or inward, so that the top of the buckle is connected to or disconnected from the connecting ring in the slot, thereby clamping or loosening the cover.

[0064] According to the disclosed embodiment, an adjustment cord is disposed around the outer edge of the bottom of the buckle and connected to a control assembly. The control assembly can be operated to control the movement of the adjustment cord to tighten or loosen the bottom of the buckle, tilting the top of the buckle outward or inward, thereby connecting or disconnecting the top of the buckle with a connecting ring within the slot, thereby allowing the cover to clamp or loosen the jacket. When the cover clamps the jacket, the cover and jacket fit more snugly, providing better support for the passenger's back and improving riding comfort. When the cover loosens the jacket, the jacket and jacket can be easily separated, making it easier to replace the jacket or cover.

[0065] Figure 1 An exploded view of a backrest according to an embodiment of the present disclosure is schematically shown. Figure 2 A perspective view of a cover according to an embodiment of the present disclosure is schematically shown. Figure 3 A perspective view schematically shows an adjusting portion in a seat according to a first embodiment of the present disclosure, wherein a cover is shown.

[0066] The present disclosure will be described in detail below with reference to the first embodiment. Figures 1 to 3 As shown, the backrest of the seat includes a cover 1, a cover 2 and an adjustment part 3. The cover 1 and the cover 2 can be made of carbon fiber material. The cover 1 can be provided with a backrest frame 15. The backrest frame 15 can divide the cover 1 into a first part 12 and a second part 13. The first part 12 can be represented as a head adjustment area. The second part 13 can be represented as a back adjustment area. A plurality of buckles 11 are provided on the peripheral sides of the first part 12 and the second part 13. The buckle 11 can include vertical buckles arranged in the horizontal direction and horizontal buckles arranged in the vertical direction. The cover 2 is provided with a plurality of card slots 21. A connecting ring (not shown in the figure) is provided in each card slot 21. The buckle 11 can be inserted into the card slot 21, and the top outer edge of the buckle 11 can cooperate with the connecting ring. As shown Figure 2As shown, the top outer edge of the buckle 11 is formed with a groove 111, which can mate with a connecting ring (not shown) in the slot 21. The cover 1 can be fitted onto the outer jacket 2 based on the mating of the connecting ring and the buckle 11. The side of the outer jacket 2 facing away from the cover 1 can be used to support the passenger.

[0067] The adjustment portion 3 includes an adjustable cord 31 and a control assembly 32. The adjustment cord 31 can be a synthetic fiber cord, a metal-based cord, or a natural fiber cord with high tensile strength. The control assembly 32 can be located between the first portion 12 and the second portion 13 and extend from within the housing 1 to the outside of the housing 1, meaning that the control assembly 32 can be operated from outside the housing 1. The adjustment cord 31 can be arranged around the outer edges of the bottoms of the multiple buckles 11, meaning that the adjustment cord 31 can surround the bottoms of the buckles 11. The ends of the adjustment cord 31 are movably connected to the control assembly 32. By operating the control assembly 32, the adjustment cord 31 can be moved, thereby tightening or loosening the bottoms of the buckles 11. The buckles 11 can have a certain degree of elasticity, so that when the adjustment cord 31 tightens the buckle 11, the buckle 11 deforms, causing the top of the buckle 11 to tilt outward, causing the groove 111 at the top of the buckle to connect with the connecting ring in the clamping slot 21, thereby clamping the housing 1 to the outer shell 2. When the adjustment rope 31 loosens the bottom of the buckle 11, the buckle 11 returns to its untightened state based on the elastic member, the top of the buckle 11 tilts inward, and the groove 111 is disconnected from the connecting ring, thereby loosening the cover 1 from the jacket 2.

[0068] Furthermore, if Figures 1 to 3 As shown, the control component 32 can be arranged on the inner side of the buckle 11. The adjusting rope 31 turns from the outer edge of the buckle 11 and extends to the inner side of the buckle 11 to connect with the control component 32. The portion of the adjusting rope 31 arranged around the outer edge of the buckle 11 can be called a compression portion. The portion of the adjusting rope 31 arranged on the inner side of the buckle 11 can be called a stretching portion. By controlling the movement of the adjusting rope 31, the length of the compression portion of the adjusting rope 31 can be gradually reduced and the length of the stretching portion can be gradually increased, thereby tightening the bottom of the buckle 11. By controlling the movement of the adjusting rope 31, the length of the compression portion of the adjusting rope 31 can be gradually increased and the length of the stretching portion can be gradually reduced, thereby loosening the bottom of the buckle 11.

[0069] Furthermore, if Figures 1 to 3As shown, according to an embodiment of the present disclosure, the control component 32 may include an operating member 33, a rotating member 34 and a moving portion 35. The operating member 33 may extend from outside the cover 1 to inside the cover 1. The rotating member 34 may be connected to the operating member 33, and the rotating member 34 may be rotated by rotating the operating member 33. The moving portion 35 may be threadedly connected to the rotating member 34, and the moving portion 35 may be moved along the rotating member 34 by rotating the rotating member 34. The moving portion 35 may be connected to the end of the adjustment rope 31. By operating the operating member 33 to rotate, the moving portion 35 may drive the adjustment rope 31 to move together, so that the bottom of the buckle 11 can be tightened or loosened more conveniently.

[0070] like Figure 3 As shown, according to the embodiment of the present disclosure, both ends of the adjustment rope 31 are connected to the same end of the rotating member 34 through the moving portion 35 (as shown in FIG. Figure 3 The two ends of the adjustment rope 31 can be connected to the moving part 35 by the connecting member 36. By providing the connecting member 36, the connecting member 36 can play a transition role, avoiding the adjustment rope 31 from being directly connected to the moving part 35 and causing the adjustment rope 31 to tilt, thereby allowing the adjustment rope 31 to move more stably. In this embodiment, the adjustment rope 31 can be a complete rope-shaped structure. The two ends of the adjustment rope 31 can be relatively arranged on both sides of the rotating member 34 (such as Figure 3 By rotating the operating member 33, the moving portion 35 can drive both ends of the adjustment rope 31 to move together, thereby accelerating the adjustment speed.

[0071] like Figure 3 As shown, according to an embodiment of the present disclosure, the housing 1 may further be provided with a plurality of guide wheels 5. The adjustment rope 31 is disposed around the outer edges of the plurality of guide wheels 5 so as to move under the guidance of the guide wheels 5, thereby causing the adjustment rope 31 to move along a predetermined trajectory and preventing the adjustment rope 31 from deviating from the movement trajectory. Under the guidance of the guide wheels 5, the adjustment rope 31 can be smoothly turned from the outer edge of the buckle 11 to the inner side of the buckle 11. The guide wheels 5 may be formed with a wheel groove, the depth of which can constrain the adjustment rope 31 and prevent the adjustment rope 31 from loosening.

[0072] like Figure 3 As shown, according to an embodiment of the present disclosure, the cover 1 is further formed with a guide channel 6 that allows the adjustment rope 31 to pass through. The adjustment rope 31 moves under the guidance of the guide channel 6, thereby further moving the adjustment rope 31 along a predetermined trajectory, preventing the adjustment rope 31 from deviating from the movement trajectory. The guide channel 6 can be formed at a position of the cover 1 where it is inconvenient to install the guide wheel 5. For example, the guide channel 6 can be formed in the backrest frame 15 and located at the lower part of the back adjustment area. The guide channel 6 can extend downward at an angle so that the adjustment rope 31 can turn and extend to the inner side of the buckle 11 more smoothly.

[0073] like Figure 3 As shown, according to an embodiment of the present disclosure, guide rings 7 may be provided on both sides of the operating member 33. The two ends of the adjustment rope 31 may pass through the guide rings 7 and connect to the movable portion 35. The provision of the guide rings 7 can prevent interference between the adjustment rope 31 and the operating member 33, thereby improving the stability of the adjustment portion 3.

[0074] Figure 4 A side view of a positioning hole and a limiting block according to an embodiment of the present disclosure is schematically shown.

[0075] like Figure 4 As shown, according to an embodiment of the present disclosure, a limiting block 331 can be formed on one side of the operating member 33 extending out of the cover 1. A handle 332 for operation can be formed on the side of the operating member 33 extending out of the cover 1. The limiting block 331 can be movably connected to the handle 332. A plurality of positioning holes 14 are formed on the side wall of the cover 1 near the operating member 33. Through operation, the limiting block 331 can be inserted into one of the plurality of positioning holes 14, thereby preventing the operating member 33 from rotating incorrectly, so that the buckle 11 can maintain a state of clamping the jacket 2 or a state of loosening the jacket 2 more stably. The side of the operating member 33 extending out of the cover 1 can be constructed into a wheel-like structure.

[0076] Figure 5 A perspective view schematically shows a mid-seat adjustment portion according to a second embodiment of the present disclosure, wherein a cover is shown. Figure 6 yes Figure 5 A partial enlarged view of the embodiment shown.

[0077] The present disclosure will be described in detail below with reference to the second embodiment. Figures 5 and 6 As shown, unlike the first embodiment in which the adjustment rope 31 is a complete rope-shaped structure, in this embodiment, the adjustment rope 31 may include a first adjustment sub-rope 311 and a second adjustment sub-rope 312. The first adjustment sub-rope 311 and the second adjustment sub-rope 312 may be arranged on opposite sides of the control assembly 32.

[0078] Furthermore, the first adjusting sub-cord 311 is disposed around the outer edge of the bottom of the buckle 11 of the first portion 12, and extends from the outside of the first portion 12 to the inside of the first portion 12 to connect with the movable portion 35. The second adjusting sub-cord 312 is disposed around the outer edge of the bottom of the buckle 11 of the second portion 13, and extends from the outside of the second portion 13 to the inside of the first portion 12 to connect with the movable portion 35.

[0079] Furthermore, the moving portion 35 includes a first moving member 351 and a second moving member 352, respectively provided at both ends of the rotating member 34. The first moving member 351 is threadedly connected to the rotating member 34. The second moving member 352 is threadedly connected to the rotating member 34. The threads of the rotating member 34 connected to the first moving member 351 and the threads of the rotating member 34 connected to the second moving member 352 have opposite rotation directions, so that when the rotating member 34 rotates, the first moving member 351 and the second moving member 352 move toward or away from each other.

[0080] The two ends of the first regulating sub-string 311 are respectively connected to the first side of the first moving member 351 (such as Figure 5 The upper side of the first moving member 351 shown in FIG) and the first side of the second moving member 352 (as shown in FIG). Figure 5 When the rotating member 34 rotates, the first and second movable members 351 and 352 drive the ends of the first adjusting sub-cord 311 to move toward or away from each other, thereby tightening or loosening the bottom of the buckle 11 of the first portion 12. When the ends of the first adjusting sub-cord 311 move toward each other, the bottom of the buckle 11 of the first portion 12 is tightened. When the ends of the first adjusting sub-cord 311 move away from each other, the bottom of the buckle 11 of the first portion 12 is loosened.

[0081] The two ends of the second regulating sub-string 312 are respectively connected to the second side of the first moving member 351 (such as Figure 5 The lower side of the first moving member 351 shown in FIG) and the second side of the second moving member 352 (as shown in FIG). Figure 5 When the rotating member 34 rotates, the first movable member 351 and the second movable member 352 drive the two ends of the second adjusting sub-cord 312 to move toward or away from each other, thereby tightening or loosening the bottom of the buckle 11 of the second portion 13. When the two ends of the second adjusting sub-cord 312 move toward each other, the bottom of the buckle 11 of the second portion 13 is tightened. When the two ends of the second adjusting sub-cord 312 move away from each other, the bottom of the buckle 11 of the second portion 13 is loosened.

[0082] According to the disclosed embodiment, by arranging the first moving member 351 and the second moving member 352 at the two ends of the rotating member 34. The rotating member 34 can drive the first moving member 351 and the second moving member 352 to move toward or away from each other. By arranging the first adjusting sub-cord 311, the first moving member 351 and the second moving member 352 are connected respectively, the two ends of the first adjusting sub-cord 311 can be controlled to move toward or away from each other, that is, the first adjusting sub-cord 311 can be applied with tension from the two ends of the first adjusting sub-cord 311, thereby the first adjusting sub-cord 311 can be tightened or loosened more evenly at the bottom of the buckle 11 of the first part 12. By arranging the first moving member 351 and the second moving member 352 at the two ends of the second adjusting sub-cord 312, the two ends of the second adjusting sub-cord 312 can be controlled to move toward or away from each other, that is, the second adjusting sub-cord 312 can be applied with tension from the two ends of the second adjusting sub-cord 312, thereby the second adjusting sub-cord 312 can be tightened or loosened more evenly at the bottom of the buckle 11 of the second part 13. Furthermore, since the first adjusting sub-string 311 and the second adjusting sub-string 312 are respectively connected to the rotating member 34 through the first moving member 351 and the second moving member 352, the first adjusting sub-string 311 and the second adjusting sub-string 312 can be moved simultaneously by rotating the operating member 33, so that the adjusting string 31 can tighten or loosen the bottom of the buckle 11 of the cover 1 more evenly and quickly, thereby making the top of the buckle 11 more evenly and quickly tilt outward or inward, so as to achieve a more even and rapid clamping or loosening of the jacket 2 by the cover 1.

[0083] It should be noted that other structures of the seat in the embodiment of the present disclosure are similar to those in the first embodiment and will not be described in detail here.

[0084] Figure 7 A perspective view schematically shows an adjusting portion in a seat according to a third embodiment of the present disclosure, wherein a cover is shown. Figure 8 yes Figure 7 A partial enlarged view of the embodiment shown.

[0085] The present disclosure will be described in detail with reference to the third embodiment. Figures 5 and 6As shown, in this embodiment, the backrest of the seat may further include an elastic portion 4. The first adjusting sub-cord 311 and / or the second adjusting sub-cord 312 are connected to the elastic portion 4 so as to move under the elastic force of the elastic portion 4. By providing the elastic portion 4, a buffer can be provided for the movement of the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312, the impact on the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312 can be absorbed and the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312 can be made to have uniform tension, so that the adjusting portion 3 can more stably tighten or loosen the bottom of the buckle 11 of the first part 12 and / or the second part 13, avoiding damage to the buckle 11 due to excessive tightening of the bottom of the buckle 11, and preventing stress concentration at the connection between the outer cover 2 and the cover shell 1, thereby improving the durability and comfort of the backrest.

[0086] According to the embodiment of the present disclosure, the first adjusting sub-string 311 and / or the second adjusting sub-string 312 include a first rope segment 313 and a second rope segment 314. The first end of the first rope segment 313 and the second rope segment 314 (such as Figure 7 The upper ends of the first rope segment 313 and the second rope segment 314 are connected to the first moving member 351 and the second moving member 352 respectively. Figure 7 The lower ends of the first and second rope segments 313, 314 are respectively connected to the elastic portion 4. By configuring the first and / or second adjustment sub-rods 311, 312 as the first and second rope segments 313, 314, the first and second rope segments 313, 314 can independently respond to elastic forces, thus preventing adjustment failure due to local deformation or wear of the first and second rope segments 313, 314.

[0087] In some other embodiments, the first adjusting sub-string 311 and / or the second adjusting sub-string 312 may also be a complete rope-shaped structure. The elastic portion 4 may be provided between the moving portion 35 and the first adjusting sub-string 311 and / or the second adjusting sub-string 312.

[0088] According to the embodiment of the present disclosure, the elastic part 4 may include a slide rod 41, two elastic members 42 and two sliding members 43. The two ends of the slide rod 41 respectively form a limited area. Baffles 44 are respectively provided on both sides of the limited area. The two elastic members 42 are respectively sleeved on the limited area of ​​the slide rod 41. The limited area limits the movable area of ​​the elastic member 42 through the baffle 44. The first end of the two sliding members 43 (such as Figure 8 The right end of the left sliding member 43 and the left end of the right sliding member 43 are respectively sleeved on one side of the limiting area close to the center of the slide rod 41 (as shown in FIG. Figure 8The two sliding members 43 move relative to each other following the first and second rope segments 313, 314, thereby loosening the elastic member 42. When the operating control component 32 drives the first and second rope segments 313, 314 to loosen the bottom of the buckle 11, the two sliding members 43 move relative to each other following the first and second rope segments 313, 314, thereby loosening the elastic member 42. When the operating control component 32 drives the first and second rope segments 313, 314 to tighten the buckle 11, the two sliding members 43 move opposite to each other following the first and second rope segments 313, 314, thereby compressing the elastic member 42. In the process of the sliding member 43 compressing the elastic member 42, the elastic member 42 exerts a reaction force on the first and second rope segments 313, 314 based on its elasticity, thereby causing the first and second rope segments 313, 314 to move more evenly.

[0089] It should be noted that other structures of the seat in the embodiment of the present disclosure are similar to those in the first embodiment and / or the second embodiment, and will not be described in detail here.

[0090] The present disclosure also provides a rail vehicle, which includes a seat as described in any one of the above embodiments.

[0091] According to the embodiment of the present disclosure, by providing an adjustment cord 31 disposed around the outer edge of the bottom of the buckle 11 and connected to the control assembly 32, the adjustment cord 31 can be controlled to move by operating the control assembly 32 to tighten or loosen the bottom of the buckle 11, so that the top of the buckle 11 tilts outward or inward, so that the top of the buckle 11 is connected to or disconnected from the connecting ring in the slot 21, thereby allowing the cover 1 to clamp or loosen the jacket 2. When the cover 1 clamps the jacket 2, the cover 1 and the jacket 2 can fit more closely together, so that the passenger's back can be better supported, thereby improving riding comfort. When the cover 1 loosens the jacket 2, the jacket 2 and the cover 1 shell can be separated more easily, thereby facilitating the replacement of the jacket 2 or the cover 1.

[0092] By setting the movable part 35 to be connected to the end of the adjustment rope 31, the movable part 35 to be threadedly connected to the rotating member 34, and the rotating member 34 to be connected to the operating member 33, the bottom of the buckle 11 can be tightened or loosened more conveniently by rotating the operating member 33.

[0093] By setting the adjustment rope 31 to be connected to the rotating part 34 of the control component 32 through the connecting part 36, the connecting part 36 can play a transition role, avoiding the adjustment rope 31 being directly connected to the moving part 35 and causing the adjustment rope 31 to tilt, thereby making the adjustment rope 31 move more stably.

[0094] By setting the guide wheel 5, the adjusting rope 31 can move under the guidance of the guide wheel 5, so that the adjusting rope 31 moves along the predetermined track, preventing the adjusting rope 31 from deviating from the moving track, and by setting a wheel groove on the guide wheel 5, the adjusting rope 31 can be prevented from loosening.

[0095] By providing the guide channel 6 , the adjustment rope 31 can be turned and extended to the inner side of the buckle 11 more smoothly.

[0096] The guide ring 7 can avoid interference between the adjusting rope 31 and the operating member 33 , thereby improving the stability of the adjusting portion 3 .

[0097] By providing the limiting block 331 and the positioning hole 14 , the operating member 33 can be prevented from rotating erroneously, so that the buckle 11 can maintain a state of clamping the jacket 2 or a state of loosening the jacket 2 in a relatively stable manner.

[0098] By connecting the first moving member 351 and the second moving member 352 at both ends of the first adjusting sub-string 311, the two ends of the first adjusting sub-string 311 can be controlled to move toward or away from each other, thereby making the first adjusting sub-string 311 more evenly tighten or loosen the bottom of the buckle 11 of the first part 12. By connecting the first moving member 351 and the second moving member 352 at both ends of the second adjusting sub-string 312, the two ends of the second adjusting sub-string 312 can be controlled to move toward or away from each other, thereby making the second adjusting sub-string 312 more evenly tighten or loosen the bottom of the buckle 11 of the second part 13. Furthermore, since the first adjusting sub-string 311 and the second adjusting sub-string 312 are respectively connected to the rotating member 34 through the first moving member 351 and the second moving member 352, the first adjusting sub-string 311 and the second adjusting sub-string 312 can be moved simultaneously by rotating the operating member 33, so that the adjusting string 31 can tighten or loosen the bottom of the buckle 11 of the cover 1 more evenly and quickly, thereby making the top of the buckle 11 more evenly and quickly tilt outward or inward, so as to achieve a more even and rapid clamping or loosening of the jacket 2 by the cover 1.

[0099] By setting the elastic part 4, a buffer can be provided for the movement of the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312, the impact of the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312 can be absorbed and the first adjusting sub-cord 311 and / or the second adjusting sub-cord 312 can be made to have uniform tension, so that the adjusting part 3 can more stably tighten or loosen the bottom of the buckle 11 of the first part 12 and / or the second part 13, avoiding damage to the buckle 11 due to excessive tightening of the bottom of the buckle 11, and preventing stress concentration at the connection between the outer cover 2 and the cover shell 1, thereby improving the durability and comfort of the backrest.

[0100] The above describes the embodiments of the present disclosure. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Although each embodiment has been described separately above, this does not mean that the measures in each embodiment cannot be advantageously used in combination. Without departing from the scope of the present disclosure, those skilled in the art may make various substitutions and modifications, which should all fall within the scope of the present disclosure.
