Description

Technical Field

[0001] The invention relates to an in-vehicle equipment system for a city rail vehicle, in particular to a seat which can be switched horizontally and vertically for a city rail vehicle. Background Art

[0002] So far, in the field of urban rail vehicles, electric rotating seats are only used in the 40000 series vehicles of Seibu Railway in Japan. In other domestic and foreign urban rail markets, urban rail vehicles are mostly set with fixed non-reversing seats. With the increase in urban population density, fast and convenient rail transit vehicles have become the first choice for daily travel. For densely populated cities, there is an urgent need for a seat that can quickly switch horizontally and vertically to balance the differentiated needs of standing space and comfort during time-sharing. Summary of the invention

[0003] The purpose of the present invention is to adjust the standing space area of ​​the aisle of the passenger compartment through the horizontal and vertical adjustment functions of the seats. When the passenger flow is large, the driver and crew can change the direction of the seats of the entire train with one button operation through the driver's console or remotely control the change of the seats of the entire train through OCC. The seats can be arranged longitudinally to provide more aisle space for passengers to stand; when the passenger flow is small, the seats are arranged horizontally to provide passengers with a larger exclusive space.

[0004] To achieve the above-mentioned object, the present invention provides a seat for urban rail vehicles that can be converted vertically and horizontally, including a stainless steel seat component and a lower mechanism, wherein the stainless steel seat component includes a seat seat component, a spindle seat component, a driving connecting rod component, a spindle, a short pad, a long pad, a plurality of blocks, a bearing retaining ring, and a spindle cover, wherein the spindle seat component, the driving connecting rod component, the spindle and the bearing retaining ring are integrated and installed on the seat seat component by hexagonal head bolts, the short pad, the long pad and the plurality of blocks are installed on the main bearing seat component frame on the lower surface of the seat seat component by using hexagon socket cylindrical head screws, and the spindle cover is installed on the spindle by using hexagon socket countersunk screws;

[0005] The lower mechanism includes a frame, a vertical clearance eliminating mechanism, a motor, a gear transmission mechanism, a crank slider mechanism, and a time-sharing controlled rotary motion cam mechanism. The vertical clearance eliminating mechanism, the motor, the gear transmission mechanism, the crank slider mechanism, and the time-sharing controlled rotary motion cam mechanism are located in the frame. The input signal is sent to the motor, and part of the motor power is output to the crank slider mechanism through the gear transmission mechanism, and part of it is output to the time-sharing controlled rotary motion cam mechanism. At the same time, it is output to the cam in the gear transmission mechanism and causes the cam to rotate. The crank slider mechanism realizes the extension and retraction of the seat, and the time-sharing controlled rotary motion cam mechanism controls the seat to rotate.

[0006] Furthermore, the frame includes a welded frame component, a hinge component, a spring bracket component, a connecting rod shaft seat component, a lower door component, a lower right door component, 4 wedge-shaped modules, a lower front baffle component, a left gas spring component, a right gas spring component, a first signal bracket component, a second signal bracket component, a lock block component, a lower rear baffle, a lower left baffle, a lower right baffle, a reset gas spring seat, a guide rail, a spring, a rotary lock and a travel switch; the hinge component is installed on the welded frame component using a hexagonal head bolt, the rotary lock and the lower left door component are integrated and installed on the hinge component using a locking nut through the self-provided welding bolts, the spring and spring bracket component are integrated and installed on the welded frame component using a hexagonal head screw and a hexagonal countersunk screw, and the connecting rod shaft seat component is installed using a hexagonal cylindrical head screw Installed on the welded frame assembly, the rotary lock and the lower right door assembly are integrated and installed on the hinge assembly using a locking nut through the built-in welding bolts. The four wedge-shaped module assemblies are respectively installed on the four right angles of the welded frame assembly using hexagonal flat round head screws. The lower front baffle assembly, lower rear baffle assembly, lower left baffle assembly and lower right baffle assembly are welded to the welded frame assembly. The left gas spring assembly, right gas spring assembly and reset gas spring seat are installed between the wedge-shaped module assemblies using hexagonal head bolts. The first signal bracket assembly and the second signal bracket assembly are installed on the welded frame assembly using hexagonal cylindrical head screws. The lock block assembly is fixed to the welded frame assembly using hexagonal cylindrical head screws. The guide rail is welded to the welded frame assembly, and the travel switch is installed on the welded frame assembly using flat round head bolts.

[0007] Furthermore, the time-sharing controlled rotational motion cam mechanism comprises a cam groove, a driving arm, a small connecting rod, a linkage large gear and a small rotating arm. The time-sharing controlled rotational motion cam mechanism is connected to the main shaft through the seat rotating shaft seat. The linkage large gear is connected to the motor for power input, driving the small connecting rod to rotate, and controlling the movement of the driving arm through the cam groove. The driving arm drives the small rotating arm to rotate, and finally controls the rotation of the main shaft and drives the seat to rotate. Under the condition of continuous power input of the linkage large gear, the seat rotation is controlled and stopped through the cam groove.

[0008] Furthermore, the first hinge point between the small connecting rod and the driving arm moves in the cam groove to control whether the first hinge point rotates around the second hinge point between the small rotating arm and the driving arm. If the first hinge point rotates around the second hinge point, the seat is in a moving state. If the second hinge point rotates around the main axis of the seat, the seat is in a rotating state. The cam groove design is used to control the timing of seat rotation and lock the seat rotation.

[0009] Furthermore, the crank slider mechanism includes a short connecting rod and a long connecting rod. The motor drives the short connecting rod to rotate, changes the angle between the short connecting rod and the long connecting rod, and drives the entire mechanism to move along the guide rail. The short connecting rod rotates 360 degrees to complete an action cycle. At this time, the angle between the short connecting rod and the long connecting rod is 0 degrees, forming a self-locking state, and the entire mechanism cannot be driven in reverse to move, thereby achieving the purpose of locking the entire mechanism.

[0010] Furthermore, the gear transmission mechanism is a link between the crank slider mechanism and the time-sharing controlled rotary motion cam mechanism and realizes continuous power transmission. When the seat completes a state switching action sequence, that is, completes the extended linear motion, completes the rotation plus linear compound motion and completes the retracted linear motion, the crank slider mechanism realizes the extension and retraction movement of the seat, and the time-sharing controlled rotary motion cam mechanism realizes that the seat does not rotate during the extension and retraction process, and only the intermediate process realizes the seat rotation. In the gear transmission ratio, the rotation angle of the time-sharing controlled rotary motion cam mechanism is 108°, and the rotation angle of the crank slider is 360°, so the final gear transmission ratio is 10:3, and there are 5 gears in total.

[0011] Furthermore, the gear transmission mechanism also includes a cam, which controls the length of the short connecting rod in the crank slider, thereby controlling the extension and retraction of the seat to ensure that the crank slider mechanism is in a dead point state after the seat movement is completed.

[0012] The seat of the present invention is a new type of passenger compartment seat, which can quickly change the direction of the seat to meet people's needs for riding comfort and space, and to reduce the pressure of riding during peak hours. At present, the seats of domestic subway vehicles are relatively old, and the installation method is mostly fixed, and it is impossible to adjust horizontally and vertically. The present invention improves the seat structure on the basis of the fixed seat structure, and adds an electric rotating device, a translation device and a limit fixing device on this basis to realize the horizontal and vertical conversion function of the seat, so as to adjust the space of the aisle area of ​​the vehicle. When the flow of people is large, the seats can be arranged vertically to provide more aisle space for passengers to stand; when the flow of people is small, the seats are arranged horizontally for passengers to sightsee. For this reason, a new type of passenger compartment seat that is simple, fresh and elegant, humanized and can provide passengers with a high-quality riding environment has been developed.

During the movement of the seat, the travel switch 30, the first signal bracket component 20 and the second signal bracket component 2 are used to monitor the status of the seat, and the status signal is output by triggering the status switch.

[0033] Reference Fig.10The lower mechanism includes a frame, a vertical clearance eliminating mechanism 40, a motor 35, a gear transmission mechanism, a crank slider mechanism, and a time-sharing control rotation motion cam mechanism.

[0034] Reference Figures 6 to 9 The hinge component 11 in the frame is installed on the welded frame component 10 using a hexagonal bolt, the rotary lock 29 is integrated with the left lower door component 14 and is installed on the hinge component 11 using a locking nut through the self-provided welded bolts, the spring 28 is integrated with the spring bracket component 12 and is installed on the welded frame component 10 using a hexagonal screw and a hexagonal countersunk screw, the connecting rod shaft seat component 13 is installed on the welded frame component 10 using a hexagonal cylindrical head screw, the rotary lock 29 is integrated with the right lower door component 15 and is installed on the hinge component 11 using a locking nut through the self-provided welded bolts, there are four wedge-shaped module components 16, and the wedge-shaped module components 16 are respectively installed using hexagonal flat round head screws. Installed on the four right angles of the welding skeleton component 10, the lower front baffle component 17, the lower rear baffle 23, the lower left baffle 24, and the lower right baffle 25 are welded to the welding skeleton component 10, the left gas spring component 18, the right gas spring component 19 and the reset gas spring seat 26 are installed between the wedge module component 16 using hexagonal head bolts, the first signal bracket component 20 and the second signal bracket component 21 are installed on the welding skeleton component 10 using hexagonal cylindrical head screws, the locking block component 22 is fixed to the welding skeleton component 10 using hexagonal cylindrical head screws, the guide rail 27 is welded to the welding skeleton component 10, and the travel switch 30 is installed on the welding skeleton component 10 using flat round head bolts.

[0035] Reference Fig.11 The crank slider mechanism includes a short connecting rod 38 and a long connecting rod 39. One end of the short connecting rod 38 is connected to the motor 35 for power input to realize the linear motion of the seat. At the same time, the power input for the rotation of the seat is realized through gear transmission. The cam 37 in the gear transmission mechanism realizes the change in length of the short connecting rod during the movement, ensuring that after the seat movement is completed, the crank slider mechanism is in a dead point state, and finally the seat is locked. In the crank slider mechanism, the motor drives the short connecting rod 38 to rotate, changes the angle between the short connecting rod 38 and the long connecting rod 39, and drives the entire mechanism to move along the guide rail 27. The short connecting rod 38 rotates 360 degrees to complete an action cycle. At this time, the angle between the short connecting rod 38 and the long connecting rod 39 is 0 degrees (parallel state), forming a self-locking state, and the entire mechanism cannot be driven in reverse to move, thereby achieving the purpose of locking the entire mechanism.

[0036] Reference Fig.12The cam mechanism for time-sharing control of rotational motion includes a cam groove 33, a driving arm 32, a small connecting rod 34, a linkage gear 36 and a small rotating arm 31. The linkage gear 36 is connected to the motor 35 for power input, driving the small connecting rod 34 to rotate, and controlling the movement of the driving arm 32 through the cam groove 33. The driving arm 32 drives the small rotating arm 31 to rotate, and finally controls when to drive the seat to rotate. Therefore, under the condition of continuous power input of the linkage gear 36, the seat rotation and stop rotation are controlled through the cam groove 33. When the seat stops rotating, the linkage gear 36 continues to rotate to realize the locking of the seat rotation.

[0037] The first hinge point between the small connecting rod 34 and the driving arm 32 moves in the cam groove 33 to control whether the first hinge point rotates around the second hinge point between the small rotating arm 31 and the driving arm 32. If the first hinge point rotates around the second hinge point, the seat is in a moving state; if the second hinge point rotates around the main axis 4, the seat is in a rotating state. The cam groove 33 is designed to control the timing of the seat rotation and lock the seat rotation.

[0038] The gear transmission mechanism is a link between the crank slider mechanism and the time-sharing control rotary motion cam mechanism, realizing continuous power transmission. The seat completes a state switching action sequence: linear motion (extension), rotation + linear compound motion, linear motion (retraction). The crank slider mechanism realizes the extension and retraction of the seat. Since the cam groove 33 in the time-sharing control rotary motion cam mechanism is curved, the drive arm 32 realizes that the seat does not rotate during the extension and retraction process when moving on both sides. Only the drive arm 32 realizes the rotation of the seat in the middle part of the cam groove 33, thereby completing the linear motion (extension), rotation + linear compound motion, and linear motion (retraction).

[0039] In the gear transmission ratio, the rotation angle of the time-sharing control rotary motion cam mechanism is 108°, and the rotation angle of the crank slider is 360°, so the final gear transmission ratio is 10:3, with a total of 5 gears (including the linkage large gear 36).

[0040] The linear motion and locking of the seat are achieved by using a crank slider mechanism and a cam transmission mechanism in combination. The rotational locking and anti-rollover locking of the seat are achieved by using the linear motion of the seat. The linear motion locking of the seat is achieved by using the dead point position of the crank slider mechanism.

[0041] Movement process: input signal to motor 35, part of the power of motor 35 is output to the short connecting rod 38 in the crank slider mechanism through the gear transmission mechanism, and part of it is output to the small connecting rod 34 in the time-sharing control rotary motion cam mechanism, and at the same time it is output to the cam 37 in the gear transmission mechanism to realize the rotation of cam 37, the crank slider mechanism realizes the extension and retraction action of the seat (continuously), the time-sharing control rotary motion cam mechanism controls the timing of the seat rotation, and the cam 37 controls the length of the short connecting rod in the crank slider, thereby controlling the extension and retraction of the seat, and finally achieving the locking of the seat surface.
