[0041] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] Figure 1 and Figure 2 This is a simplified description of a seat's structure from different perspectives, and does not constitute a limitation on the seat itself; it is merely for the purpose of describing the seat's structure. The seat can be a single seat or multiple seats arranged in a row. Taking a single seat as an example... Figure 1 The X arrow indicates the width of a single seat, and the Y arrow indicates the length of a single seat. In the length direction of the seat, the end of the seat away from the backrest is the front end of the seat, and the end of the seat closer to the backrest is the rear end of the seat.

[0045] This application provides a seat that can be used in urban railway vehicles. The seat includes a frame 100 and a cushion 200.

[0046] The frame 100, serving as the supporting base for the seat, can be made of aluminum alloy, allowing it to reduce its weight while maintaining structural strength. The frame 100 includes a seat cushion frame 110 for supporting the seat cushion 200, on which the seat cushion 200 is mounted.

[0047] Please see Figure 3 and Figure 4The seat cushion 200 includes a seat cushion body 210 and a seat cushion plate 220, which are connected. The seat cushion body 210 and the seat cushion plate 220 can be an integral structure to ensure a tight connection and facilitate the overall installation of the seat cushion 200. The seat cushion body 210 can be made of a material with a certain degree of elasticity and wear resistance, such as silicone leather, to improve the scratch resistance and water resistance of the seat cushion 200.

[0048] The seat cushion 220 can be made of high-strength lightweight metals or engineering plastics, such as aluminum alloys, thus balancing structural strength and lightweight requirements.

[0049] The seat frame 110 is provided with a plug groove 111 and a first connecting part 112, and the seat plate 220 includes a plug part 221 and a second connecting part 222.

[0050] The insertion slot 111 can be a groove structure, hole structure, ring structure, etc., formed on the top or side surface of the seat cushion frame 110. The insertion part 221 can be a protrusion structure extending from the bottom surface of the seat cushion plate 220. Its shape and size match the insertion slot 111 of the seat cushion frame 110, and it can be inserted into the insertion slot 111 to form a fitting or insertion fit. This fitting structure can realize the quick pre-positioning of the seat cushion 200 and the seat cushion frame 110, thereby reducing the difficulty of hole or alignment operations in the subsequent connection process.

[0051] The second connecting part 222 is a mating structure adapted to the structure of the first connecting part 112. The first connecting part 112 and the second connecting part 222 can be mounting holes with internal threads, lugs, or snap-fit ​​seats, etc. The first connecting part 112 and the second connecting part 222 are connected by fasteners, such as bolts, quick-release pins, etc.

[0052] For example, if the first connecting part 112 is a mounting hole with internal threads, the second connecting part 222 is a through hole that matches the diameter of the mounting hole. If the first connecting part 112 is a lug, the second connecting part 222 is a corresponding slot. Its function is to achieve the final fixation of the seat cushion 200 and the seat cushion frame 110 by cooperating with the first connecting part 112 after the insertion part 221 and the insertion slot 111 are fitted together.

[0053] During the assembly of the seat, the seat cushion body 210 and the seat cushion plate 220 are pre-assembled first. Then, the insertion part 221 on the seat cushion plate 220 is aligned with the insertion groove 111 on the seat cushion frame 110, so that the insertion part 221 is inserted into the insertion groove 111. At this time, the seat cushion 200 is initially fixed under the action of the insertion and engagement, so that the relative position with the seat cushion frame 110 can be kept stable without additional tools, effectively reducing the alignment operation during the installation of the seat cushion 200.

[0054] Then, the fastener is passed through the second connecting part 222 and the first connecting part 112 to complete the locking and fixing. Since the insertion part 221 and the insertion groove 111 have formed a partial positioning and load-bearing function, it helps to reduce the number of fasteners required. Therefore, the number of fasteners required in this embodiment is less than that of the traditional all-bolt connection method, and the fasteners only need to complete a simple locking operation, without the need for precise alignment of multiple points.

[0055] In this embodiment, the seat uses the positioning and cooperation between the plug-in part 221 and the plug-in groove 111, which helps to reduce the number of fasteners used and simplify the alignment operation during assembly, thereby reducing labor costs. At the same time, compared with the structural adhesive bonding in related technologies, this solution does not rely on structural adhesive for fixation. During disassembly, only the fasteners need to be removed to separate the plug-in part 221 from the plug-in groove 111, thereby reducing the difficulty of disassembling and assembling the seat, reducing the maintenance and replacement cycle, and reducing maintenance costs.

[0056] In some embodiments, please refer to Figure 3 and Figure 6 The insertion part 221 and the insertion slot 111 are located at the rear end of the seat, and the first connecting part 112 and the second connecting part 222 are located at the front end of the seat.

[0057] Since the rear end of the seat mainly bears less backward leaning force during passenger seating compared to the front seat pressure load, the plug-in structure can effectively limit the displacement of the seat cushion 200 in the front-back or left-right directions through plug-in cooperation. With the relatively fixed space environment at the rear end, the risk of deformation of the plug-in part 221 due to external force collision is reduced, ensuring the connection stability of the plug-in part 221 and the plug-in groove 111.

[0058] The front of the seat is close to the passenger access passage of the train or the leg movement area of ​​the seat. This area has more operating space during routine maintenance. Therefore, placing the first connecting part 112 and the second connecting part 222 here can greatly reduce the difficulty of fastener disassembly and assembly.

[0059] Therefore, during actual assembly, maintenance personnel only need to lift the seat cushion 200 from the front of the seat to the rear, aligning the insertion part 221 at the rear end of the seat cushion plate 220 with the insertion slot 111 at the rear end of the seat cushion frame 110, and push it vertically or slightly backward to achieve quick engagement of the insertion part 221 with the insertion slot 111. During disassembly and maintenance, due to ample operating space at the front, maintenance personnel do not need special tools or to crawl under the seat. They only need to use a regular wrench or screwdriver to remove the fasteners at the front, and then lift the front end of the seat cushion 200 upward to disengage the insertion part 221 from the insertion slot 111. The entire disassembly and assembly process can be completed by a single person.

[0060] In some embodiments, please refer to Figure 5To further enhance the load-bearing capacity and structural stability of the seat cushion frame 110, the seat cushion frame 110 includes a support component 113, which includes a support rod 1131 and a support plate 1132.

[0061] The support rod 1131 is provided on the seat cushion frame 110 along the width direction of the seat. The length of the support rod 1131 can match the lateral width of the seat cushion 200 to ensure that the lateral load of the seat cushion 200 can be evenly distributed.

[0062] The insertion slot 111 is provided on the support rod 1131. The insertion slot 111 can be directly opened on the support rod 1131, or it can be a slot structure fixedly connected to the structural component of the support rod 1131.

[0063] The seat cushion 220 has a first engaging groove 223 on the side near the seat cushion frame 110, which engages with the support rod 1131. The first engaging groove 223 can be an elongated groove extending along the width of the seat, and its width is adapted to the cross-sectional width of the support rod 1131. When the insertion part 221 at the rear end of the seat cushion 220 is inserted into the insertion groove 111 of the support rod 1131, the first engaging groove 223 simultaneously engages with the outer wall of the support rod 1131. In this way, a double engaging fit is formed between the seat cushion 200 and the seat cushion frame 110, thereby further restricting the displacement of the seat cushion 220 in the vertical and horizontal directions. At the same time, the load at the rear end of the seat cushion 200 can be evenly transferred to the support rod 1131 through the engaging surface, avoiding deformation of the seat cushion 220 or the frame 100 caused by local stress concentration.

[0064] The support plate 1132 is located at the front end of the seat cushion frame 110. The support plate 1132 extends along the width direction of the seat, and the first connecting part 112 is located on the support plate 1132.

[0065] The support plate 1132 can be connected to the front crossbeam of the seat cushion frame 110 by welding or bolting to form a rigid support surface. The lateral length of the support plate 1132 covers the stress area at the front of the seat cushion 200, ensuring that the load concentrated in the middle and front of the seat cushion 200 when the passenger sits is evenly distributed to the front support structure of the seat cushion frame 110, avoiding deformation of the front of the frame 100 due to excessive local stress.

[0066] Meanwhile, since the support plate 1132 is a planar structure with a large area, it is not only easy to open screw holes, but also to ensure the coaxiality and perpendicularity of the countersunk hole, avoiding fastener locking or uneven force due to uneven mounting surface.

[0067] Therefore, in this embodiment, the seat further improves the structural strength and support performance of the seat cushion frame 110 through the support component 113.

[0068] In some embodiments, please refer to Figure 5 The front end of the seat frame 110 is also provided with a support rod 1131, and a support plate 1132 is set on the upper end of the support rod 1131, thereby further improving the structural strength of the front end of the seat frame 110 and helping to ensure the support stability of the front end of the seat 200.

[0069] In some embodiments, please continue reading Figure 5 The seat frame 110 includes at least two lateral supports 114 and at least two longitudinal supports 115.

[0070] At least two lateral support members 114 are spaced apart along the width of the seat. This spacing between the two lateral support members 114 creates multiple support points in the width direction, preventing overload on a single support point when the passenger's posture shifts or when multiple people share the seat. Two lateral support members 114 can be provided, located at the front and rear edges of the seat.

[0071] The transverse support member 114 can be made of lightweight alloy profile, with an L-shaped or I-shaped cross-section. Its opening faces or is flush with the side of the seat cushion 220, ensuring sufficient bending strength while reducing the overall weight of the frame 100 through a hollow or thin-walled structure. The length of the transverse support member 114 is adapted to the width of the seat, and both ends extend to the positions where it connects with the longitudinal support member 115. Its surface has pre-drilled mounting holes or welding points for connection with the support rod 1131, support plate 1132, and longitudinal support member 115.

[0072] The longitudinal support 115 can also be made of lightweight alloy profile, and the cross section can be designed as L-shaped or I-shaped, which is convenient for connecting to the end of the transverse support 114, and can also provide auxiliary limit for the seat cushion 220 through the side extension structure to prevent the seat cushion 220 from shifting laterally.

[0073] At least two longitudinal support members 115 are arranged along the length of the seat, and the transverse support member 114 is connected to the longitudinal support member 115. The length of the longitudinal support member 115 covers the front and rear stress areas of the seat, the front end extends to a position near the front edge of the seat, and the rear end connects to the seat back frame 320 or the parts connected to the train body, so that the seat cushion frame 110 can form a stable connection with the train body through the longitudinal support member 115, and prevent the seat cushion frame 110 from shifting as a whole when the train starts and stops.

[0074] Two longitudinal support members 115 can be provided, symmetrically arranged on the left and right sides of the seat, and their extension direction is consistent with the front and back direction of the passenger's sitting posture.

[0075] The longitudinal support 115 and the transverse support 114 can be connected by welding or high-strength bolts: welding ensures that the two form a rigid node without gaps, which is suitable for scenarios with high strength requirements.

[0076] In some embodiments, please refer to Figure 5 The frame 100 also includes a vertical support 116 and a wall-mounted fastener 117.

[0077] The vertical support member 116 is connected to the seat cushion frame 110, and the vertical support member 116 is located on the lower side of the seat cushion frame 110.

[0078] The vertical support 116 serves as a vertical connection and load-bearing unit between the seat cushion frame 110 and the train body floor. One end is fixedly connected to the lower side of the seat cushion frame 110, and the other end is used to fit against the train body floor or be fixed by fasteners. It can evenly transfer the vertical seat pressure load borne by the seat cushion frame 110 to the train body, while supporting the seat cushion frame 110 to maintain a certain horizontal height.

[0079] Multiple vertical support members 116 can be provided depending on the stress on the seat, such as 2, 4, or 6. The vertical support members 116 are connected to the seat cushion frame 110 by welding or bolting: welding is suitable for scenarios with high structural rigidity requirements, ensuring that the intersections of the vertical support members 116 with the horizontal support members 114 and the longitudinal support members 115 form a rigid whole.

[0080] The vertical support 116 can be a hollow round tube or square tube structure, and the material can be the same aluminum alloy as the horizontal support 114, so that it has sufficient vertical compressive strength.

[0081] The wall-mounted fastener 117 is located on the side of the seat cushion frame 110 near the rear end. The wall-mounted fastener 117 can connect the frame 100 to the side wall of the train, restrict the displacement of the seat cushion frame 110 in the front-to-back direction, prevent the rear end of the seat from hitting the side wall of the carriage due to inertia when the train starts and stops, and at the same time strengthen the connection between the seat and the wall, improving the overall stability.

[0082] The wall-mounted fastener 117 may include a connecting section that connects to the seat cushion frame 110 and a fixing section that fits against the side wall of the carriage. The connecting section may be designed as a flat structure and fixed to the transverse support 114 or support rod 1131 at the rear end of the seat cushion frame 110 by bolts. The fixing section may be selected according to the side wall material. If the side wall is made of metal, the fixing section may be designed as a lug with mounting holes and connected to the mounting seat reserved on the side wall by bolts to form a rigid fixation.

[0083] In related technologies, fire extinguishers are usually integrated and installed under the seat frame 100 of urban rail trains. The layout requirements of waterproof electrical equipment are not taken into account, resulting in a lack of nearby installation space for electrical equipment in the middle of the carriage, which requires additional space in the passenger area or an increase in the volume of the partition cabinet.

[0084] To this end, the vertical support 116 is located on the side of the seat frame 110 near the front end, so that a space for placing waterproof electrical equipment is formed between the seat frame 110 and the vertical support 116. In this way, the unused area under the seat can be effectively utilized, which helps to alleviate the problem of tight space in the partition cabinet, and at the same time shortens the length of electrical wiring.

[0085] Please see Figure 2 and Figure 5 In this embodiment, the vertical support member 116 is located in the area of ​​the seat cushion frame 110 near the front end of the seat. This location avoids the rear end area under the seat cushion frame 110 and ensures balanced vertical load-bearing through multi-node distribution. At the same time, since the wall fastener 117 can connect the seat frame 100 to the side wall of the train, even if the vertical load is concentrated in the area of ​​the seat cushion frame 110 near the front end, the connection stability of the frame 100 can still be guaranteed.

[0086] In some embodiments, to further enhance the structural protection performance and integrity of the front end of the frame 100, and to accommodate the front-end shielding requirements of the electrical equipment placement space, please refer to [reference needed]. Figure 6 The frame 100 has a front baffle 400 on the front side near the seat.

[0087] Please see Figure 7 and Figure 8 The top of the front panel 400 is provided with a second snap-fit ​​groove 410 along the width direction of the seat, and the seat cushion frame 110 is provided with a snap-fit ​​strip 118 on the side near the front end of the seat, and the snap-fit ​​strip 118 extends along the width direction of the seat.

[0088] The front baffle 400 serves as a protective and shielding component at the front end of the frame 100. Its position corresponds to the front edge of the seat frame 110, and it can also be connected to the vertical support 116 below via screws.

[0089] The locking strip 118 is an elongated protrusion that extends integrally from the upper front surface of the seat cushion frame 110, with its length matching the second locking groove 410 of the front baffle 400. The second locking groove 410 is a recess formed at the top of the front baffle 400, with its groove shape complementary to the cross-sectional shape of the locking strip 118. In addition, the inner wall of the second locking groove 410 can be provided with slight elastic protrusions to further improve the stability after locking through interference fit, preventing the front baffle 400 from separating from the frame 100 due to vibration during train operation.

[0090] The front baffle 400 can also be fixed to the vertical support 116 with screws to further improve its installation reliability.

[0091] In this embodiment, the front baffle 400 shields the space for electrical equipment and the frame 100 structure, while also forming a protective barrier on the passenger aisle side, reducing the risk of equipment malfunctions and passenger collisions. Furthermore, the engagement of the snap-fit ​​strip 118 and the snap-fit ​​groove creates a rigid connection between the front baffle 400 and the seat cushion frame 110. Combined with the support of the vertical support member 116, this prevents the front baffle 400 from loosening due to vibration at the front of the seat, while also not occupying space for electrical equipment.

[0092] In some embodiments, the seat includes a backrest 300, which includes a backrest cushion 310 and a backrest frame 320. The backrest cushion 310 is connected to the backrest frame 320, and the backrest frame 320 is connected to the seat cushion frame 110.

[0093] The backrest cushion 310, being the component that directly contacts the passenger's back, can utilize a multi-layered composite material structure to enhance its comfort. The backrest frame 320, serving as the supporting foundation for the backrest 300, is made of the same lightweight alloy as the seat cushion frame 110 and can have an overall mesh-like structure. This mesh-like structure is formed by crisscrossing support ribs. This mesh-like structure significantly reduces weight while ensuring strength and provides even support for the backrest cushion 310, preventing localized collapse due to insufficient support points.

[0094] In some embodiments, please continue reading Figure 6 The backrest frame 320 includes a first fixing part 321 and a second fixing part 322 at the end near the seat cushion frame 110. The first fixing part 321 is connected to the transverse support member 114, and the second fixing part 322 is connected to the longitudinal support member 115.

[0095] When a passenger leans back against the backrest 300, the resulting longitudinal force is first transmitted to the backrest frame 320. Most of the longitudinal force is transmitted through the first fixing part 321 to the lateral support member 114 at the rear end of the seat cushion frame 110, and then distributed by the lateral support member 114 to the left and right longitudinal support members 115. At the same time, part of the longitudinal force is converted into an oblique component force, which is transmitted through the second fixing part 322 to the front longitudinal support member 115, and finally transmitted by the longitudinal support member 115 to the vehicle floor.

[0096] The first fixing part 321 and the second fixing part 322 can be ear plate structures extending outward from the end of the backrest frame 320. The ear plate is provided with positioning holes, and the transverse support member 114 and the longitudinal support member 115 are provided with positioning pins. The positioning holes and positioning pins are positioned and engaged, and the connection can be achieved by bolts or nuts.

[0097] On the other hand, this application also provides a motor vehicle including the seats in any of the above embodiments.

[0098] It is understood that since the train has the seats in any of the above embodiments, the train also has the beneficial effects of the seats in any of the above embodiments, so they will not be described in detail here.

[0099] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
