[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] Existing urban rail passenger vehicles are only equipped with fixed passenger seats, making it impossible to adjust the vehicle's passenger capacity according to changes in passenger flow.

[0037] To address the aforementioned technical issues, this embodiment discloses a passenger seat for a rail vehicle. The passenger seat is foldable, meaning its seat components can be flipped up and down, allowing for both storage and deployment. The folded-down seat configuration increases the interior space of the rail vehicle, making it suitable for peak operating conditions and increasing passenger capacity. Furthermore, the folded configuration meets the needs of passengers.

[0038] like Figures 1 to 5 As shown, the passenger seat of the rail vehicle in this embodiment includes a backrest assembly 1, a seat assembly 2, and a drive assembly 3.

[0039] The seat assembly 2 is connected to the first side of the backrest assembly 1, and the seat assembly 2 is rotatable relative to the backrest assembly 1. Optionally, the seat assembly 2 is rotatably mounted on the second side of the backrest assembly 1. The first and second sides of the backrest assembly 1 are two sides along its thickness direction. The first side can serve as the front, and the seat assembly 2 is mounted on the first side, creating a seating space between the seat assembly 2 and the backrest assembly 1. The second side of the backrest assembly 1 can serve as the back, and it can be fixedly connected to the vehicle's passenger compartment.

[0040] The passenger seats in this embodiment can be arranged longitudinally or laterally. It should be noted that, in this text, "longitudinal" refers to the length direction of the rail vehicle, and "lateral" refers to the width direction. The arrangement direction of the passenger seats in this text can be understood as the length direction of the passenger seats.

[0041] The drive assembly 3 is mounted on the backrest assembly 1 and is connected to the seat assembly 2, driving the seat assembly 2 to rotate relative to the backrest assembly 1. By setting the drive assembly 3, the seat assembly 2 can be electrically driven, reducing the operator's labor intensity.

[0042] The drive assembly 3 in this embodiment has a locking structure that enables the seat assembly 2 to be locked in a stowed state or an unfolded state. In the unfolded state, the seat assembly 2 is unfolded relative to the back panel assembly 1, and in the stowed state, the seat assembly 2 is stowed relative to the back panel assembly 1.

[0043] In this embodiment, the seat assembly 2 of the passenger compartment of the rail vehicle can rotate relative to the backrest assembly 1, thereby enabling the seat assembly 2 to be stowed and unfolded. The stowed state of the seat assembly 2 increases the interior space of the rail vehicle, thus meeting the needs of increasing passenger capacity during peak operating hours; the stowed state of the seat assembly 2 also satisfies the needs of passengers.

[0044] Combination Figures 2 to 5 As shown, the drive assembly 3 includes: a drive motor 31, a reduction gearbox 32, a lead screw and nut assembly, and a connecting rod 36.

[0045] The drive motor 31 serves as a power source, and its type can be selected according to different needs. The drive motor 31 can be a stepper motor. In some embodiments, the drive motor 31 can be mounted on the second side of the backplate assembly 1. Optionally, the drive motor 31 and the second side of the backplate assembly 1 can be fixedly connected by a threaded connector.

[0046] In other alternative embodiments, the power source for the drive component 3 may also be a cylinder.

[0047] Depending on the transmission speed of the drive motor 31, in some embodiments, the motor output shaft of the drive motor 31 can be connected to the reduction gearbox 32. The reduction gearbox 32 can reduce the speed transmitted to the lead screw nut assembly, reduce the rotation speed of the seat assembly 2 relative to the back panel assembly 1, alleviate the collision force during the rotation of the seat assembly 2, and reduce safety hazards.

[0048] The gearbox 32 can be installed on the second side of the back plate assembly 1. Optionally, the gearbox 32 and the second side of the back plate assembly 1 can be fixedly connected by a threaded connector.

[0049] The lead screw and nut assembly includes a lead screw 33, a nut 34, and a guide rail 35.

[0050] The lead screw 33 is rotatably mounted on the second side of the back plate assembly 1. The lead screw 33 is connected to the motor output shaft of the drive motor 31. If the motor output shaft of the drive motor 31 is connected to a reduction gearbox 32, the lead screw 33 is connected to the output end of the reduction gearbox 32.

[0051] Nut 34 is fitted onto lead screw 33 and is threaded into lead screw 33.

[0052] The guide rail 35 is fixed to the second side of the back plate assembly 1. The outer surface of the nut 34 has a protrusion that can be inserted into the guide rail 35 and cooperate with the guide rail 35, so that the protrusion can move along the guide rail 35.

[0053] Under the limiting action of the guide rail 35, during the process of the drive motor 31 driving the lead screw 33 to rotate, the nut 34 moves relative to the lead screw 33 along the axial direction of the lead screw 33.

[0054] One end of the connecting rod 36 is fixedly connected to the nut 34, so that as the nut 34 moves relative to the lead screw 33 along the axis of the lead screw 33, the connecting rod 36 also moves along the axis of the lead screw 33. The other end of the connecting rod 36 is connected to the seat assembly 2, which is hinged to the backrest assembly 1. Therefore, as the connecting rod 36 moves with the nut 34 along the axis of the lead screw 33, it will cause the seat assembly 2 to rotate relative to the position hinged to the backrest assembly 1, thereby switching the seat assembly 2 between its stowed and unfolded states.

[0055] The drive assembly 3 in this embodiment adopts a structure of drive motor 31 and lead screw and nut assembly, which simplifies the structure and ensures the stability of the drive of seat assembly 2.

[0056] It should be noted that the drive motor 31 in this article is a bidirectional motor. Optionally, the forward rotation of the drive motor 31 can realize the switching of the seat assembly 2 from the folded state to the unfolded state, and the reverse rotation of the drive motor 31 can realize the switching of the seat assembly 2 from the unfolded state to the folded state.

[0057] In some embodiments, seat assembly 2 may include seat frame 21 and seat cushion (not shown).

[0058] The seat frame 21 is hinged to the back panel assembly 1, and a connecting rod 211 is provided on the seat frame 21.

[0059] The connecting rod 211 is arranged along the width direction of the seat assembly 2, which in this text refers to the direction from one end of the seat assembly 2 connected to the backrest assembly 1 to the other end. One end of the connecting rod 211 is hinged to the connecting rod 36, and the other end of the connecting rod 211 can be fixedly connected to the seat frame 21.

[0060] The seat cushion can be detached and placed on the seat frame 21 to improve the comfort of passengers when leaning on the seat assembly 2. At the same time, when the seat cushion is folded up, it can be used as a lumbar support for passengers to lean on.

[0061] In some embodiments, the backplate assembly 1 may include a backplate frame 11 and a backplate pad (not shown in the figure).

[0062] The backrest frame 11 is hinged to the seat frame 21, and the drive assembly 3 is mounted on the backrest frame 11.

[0063] The backrest pad can be detachably placed on the backrest frame 11 to improve the comfort of the passenger in the scenario of the seat assembly 2.

[0064] like Figure 6 As shown, the passenger seats of the rail vehicle in this embodiment also include a controller 5.

[0065] In some embodiments, the drive motor 31 is provided with a brake for locking the motor output shaft, which connects the motor output shaft to the housing of the drive motor 31.

[0066] The aforementioned controller 5 controls the energization connection between the brake and the power supply equipment. When the brake is energized, it releases the motor output shaft; when the brake is de-energized, it clamps the motor output shaft. This can be understood as follows: the controller 5 controls the opening and closing of the brake. When the drive motor 31 is moving, the controller 5 inputs current to the brake, causing it to open. When the drive motor 31 stops moving, the controller 5 de-energizes the brake, and the brake automatically closes through spring action, locking the motor output shaft of the drive motor 31. This ultimately achieves the purpose of locking the seat assembly 2. Therefore, regardless of whether the vehicle is energized or not, the seat assembly 2 is in a locked state.

[0067] like Figure 6 As shown, the passenger seats of the rail vehicle in this embodiment also include an unlocking device 4.

[0068] If the folding process of seat assembly 2 malfunctions, it is necessary to manually rotate seat assembly 2. In order to achieve manual operation of seat assembly 2, it is necessary to disconnect the connection between drive motor 31 and seat assembly 2. Based on this, an unlocking device 4 is provided between drive motor 31 and lead screw 33 in this embodiment. The unlocking device 4 can be used to disconnect the transmission connection between drive motor 31 and lead screw 33, thereby disconnecting the connection between drive motor 31 and seat assembly 2.

[0069] Furthermore, a reduction gearbox 32 is also provided between the drive motor 31 and the lead screw 33. The connection between the drive motor 31 and the reduction gearbox 32 or the reduction gearbox 32 and the lead screw 33 can be disconnected. Of course, the power transmission path inside the reduction gearbox 32 can also be directly disconnected. Optionally, the power transmission path inside the reduction gearbox 32 can be disconnected by using the unlocking device 4, thereby realizing the disconnection of the transmission connection between the drive motor 31 and the lead screw 33.

[0070] It should be noted that if the drive motor 31 and the lead screw 33 are connected by a coupling, the power connection between the drive motor 31 and the seat assembly 2 can be disconnected by disconnecting the coupling between the drive motor 31 and the lead screw 33. If the output end of the gearbox 32 is connected to the lead screw 33 by a coupling, the power connection between the drive motor 31 and the seat assembly 2 can be disconnected by disconnecting the coupling between the gearbox 32 and the lead screw 33.

[0071] like Figure 7 As shown, this embodiment disconnects the force transmission path inside the reduction gearbox 32 to break the connection between the drive motor 31 and the seat assembly 2. However, other methods that can also disconnect the drive motor 31 and the seat assembly 2 are also within the scope of protection.

[0072] Combination Figure 6 and Figure 7 As shown, the unlocking device 4 includes an unlocking component 41, a connecting line 42, and a lever 43.

[0073] The gearbox 32 includes: a first transmission gear 321, a second transmission gear 322, a third transmission gear 323, and a housing 324.

[0074] The first transmission gear 321, the second transmission gear 322, and the third transmission gear 323 mesh and drive in sequence. The first transmission gear 321 is connected to the output shaft of the drive motor 31, which can be understood as the power input gear of the reduction gearbox 32. The third transmission gear 323 is connected to the output end of the reduction gearbox 32, which can be understood as the power output gear of the reduction gearbox 32.

[0075] It should be noted that the gearbox 32 may include at least two meshing transmission gears. That is, the number of transmission gears inside the gearbox 32 is not limited to the three disclosed above. Other numbers of transmission gears may be provided according to different deceleration requirements, and all of them are within the protection range.

[0076] In this embodiment, the second transmission gear 322 is connected to the lever 43. Optionally, the lever 43 is hinged to the back plate assembly 1 at its middle position, and one end of the lever 43 extends into the housing 324 of the gearbox 32 and is connected to the second transmission gear 322. Optionally, the lever 43 can also be connected to the first transmission gear 321 or the third transmission gear 323. It can be understood that at least one of the transmission gears in the gearbox 32 is connected to one end of the lever 43.

[0077] The other end of lever 43 is connected to connecting line 42. It should be noted that the middle position of lever 43 is hinged to back panel assembly 1. One end of lever 43 is connected to at least one transmission gear, and the other end of lever 43 is connected to connecting line 42. Therefore, when connecting line 42 is pulled, lever 43 will rotate around the hinge point, thereby moving the transmission gear and disengaging the transmission gear from the adjacent transmission gear, thus breaking the force transmission path inside the gearbox 32 and disconnecting the connection between drive motor 31 and seat assembly 2.

[0078] In this embodiment, the connecting line 42 can be wound around the second side of the back panel assembly 1. The winding direction and winding position of the connecting line 42 can be set according to different needs, and are not specifically limited here.

[0079] The unlocking element 41 is disposed on the first side of the back panel assembly 1. The unlocking element 41 can rotate, and during the rotation of the unlocking element 41, it pulls the connecting line 42, thereby pulling the lever 43 to rotate around the hinge point.

[0080] In some embodiments, the unlocking element 41 may be a handle. Optionally, one end of the handle is inserted from the first surface of the back plate assembly 1 to the second surface of the back plate assembly 1, and the connecting wire 42 is wound around one end of the handle; the other end of the handle is exposed on the first surface of the back plate assembly 1 to facilitate operation by the operator.

[0081] As the operator rotates the handle, the connecting wire 42 is continuously wound around the handle, reducing its length and thus pulling the lever 43, causing it to rotate around the hinge point. As the operator rotates the handle in the opposite direction, the connecting wire 42 is continuously released, increasing its length. Under the weight of the transmission gear, the lever 43 rotates in the opposite direction until the transmission gear resets and engages with the adjacent transmission gear.

[0082] The unlocking component 41 in this embodiment can be set according to different needs. As long as the structure that can pull the connecting line 42 is within the protection range, it is within the protection range.

[0083] In some embodiments, there may be at least two sets of drive components 3, and these drive components 3 may be arranged along the length direction of the backrest assembly 1. In this embodiment, the drive components 3 synchronously drive the seat assembly 2 to improve the balance of force on the seat assembly 2 along the length direction.

[0084] When there are at least two sets of drive components 3, all drive components 3 are connected to the unlocking device 4, that is, the unlocking device 4 can be used to realize the synchronous disconnection or connection of all drive components 3 and seat components 2.

[0085] Optionally, the reduction gearboxes 32 of all drive components 3 are connected to the unlocking member 41 via connecting lines 42, so that during the rotation of the unlocking member 41, the force transmission path inside the reduction gearboxes 32 of all drive components 3 can be simultaneously disconnected by the unlocking member 41, thereby realizing the synchronous disconnection of all drive motors 31 from the seat assembly 2.

[0086] In this embodiment, there are multiple drive components 3, which can improve the stability of the seat component 2 during rotation. In addition, all drive components 3 are controlled by the same unlocking component 41, which can realize the synchronous disconnection or connection of the connection between all drive components 3 and seat component 2, simplifying the structure and reducing the difficulty of operation.

[0087] In addition, this embodiment also discloses a rail vehicle including a passenger seat, wherein the passenger seat is the passenger seat disclosed in the above embodiment. Therefore, the rail vehicle with the passenger seat also has all the above-mentioned technical effects, which will not be described in detail here.

[0088] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0089] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
