Description

Technical Field

[0001] This utility model relates to the field of high-speed rail seat technology, specifically a high-speed rail seat motion frame. Background Technology

[0002] High-speed rail, or HSR for short, refers to a railway system designed to high standards and capable of allowing trains to travel safely at high speeds. To provide passengers with better rest on high-speed trains, seats are installed for passengers to relax.

[0003] High-speed rail seats consist of five main parts: seat frame, upholstery, electrical control system, motion rotation mechanism, and privacy cover. The seat frame is generally made of aluminum alloy, alloy steel, or other light alloy materials to provide basic support for passengers. When passengers need to adjust the seat back angle, the seat frame needs to be adjusted. Existing seat frame adjustments only adjust the angle of the passenger's back frame, and the frame of the passenger's buttocks cannot be adjusted adaptively, which can easily cause discomfort and fatigue during long journeys. Therefore, it is necessary to design a motion frame for high-speed rail seats. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed rail seat motion frame to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-speed rail seat motion frame, including a fixed back cover and two supporting base rods provided below the fixed back cover. A back fixing frame is provided inside the fixed back cover. A back frame main body is movably fitted on the back fixing frame. A leg fixing frame is fixed at the bottom of the back fixing frame. A hip frame main body is movably fitted at the top of the leg fixing frame.

[0006] The hip frame body and the back frame body are connected by a connecting handle mechanism;

[0007] A telescopic cylinder is mounted on the side of the hip frame body near the connecting handle mechanism via a hinge seat, and the output end of the telescopic cylinder is connected to the side of the hip frame body away from the connecting handle mechanism.

[0008] When the telescopic cylinder pushes the hip frame body to extend, the back frame body angle is adjusted. Through the operation of the telescopic cylinder, in conjunction with the hinge seat, the hip frame body is pushed to move and extend along the leg fixing frame. The connection handle mechanism allows the back frame body to be pulled while the hip frame body extends, so that the back frame body angle is adjusted, making it more convenient for passengers to sit, reducing discomfort and relieving riding fatigue.

[0009] In a further embodiment, the connecting handle mechanism includes a connecting handle one and a connecting handle two. The top of the connecting handle one is fixedly connected to the bottom of the back skeleton body, one end of the connecting handle two is fixedly connected to the adjacent hip skeleton body, and the other end of the connecting handle two is hinged to the bottom of the connecting handle one. Through the mutual hinge of the connecting handle one and the connecting handle two, when the hip skeleton body is extended, the connecting handle two pulls the connecting handle one, thereby pulling the back skeleton body.

[0010] In a further embodiment, the upper part of the back support frame is symmetrically provided with guide inclined blocks, and the guide inclined blocks are provided with moving grooves. The upper part of the back frame body is provided with a connecting beam, and the side of the connecting beam facing the guide inclined blocks is provided with a moving block that slides in cooperation with the moving groove. When the telescopic cylinder drives the back frame body to adjust the angle, the moving block slides in the moving groove. By sliding in cooperation with the moving groove, the angle adjustment of the back frame body is convenient while ensuring the stability of the back frame body angle adjustment.

[0011] In a further embodiment, a guide groove is provided on one side of the leg fixing frame, and a guide plate is fixed at the bottom of the hip frame body. The guide plate is located in the guide groove. When the telescopic cylinder pushes the hip frame body to extend, the hip frame body drives the guide plate to slide in the guide groove. Through the cooperation between the guide plate and the guide groove, the hip frame body can extend easily while ensuring the stability of the hip frame body during extension.

[0012] In a further embodiment, a limiting seat is provided on the support base rod located below the front end of the hip skeleton body. The limiting seat limits the movement of the hip skeleton body, thereby stabilizing its movement.

[0013] In a further embodiment, the back support frame is provided with several reinforcing beams, and the bottom of the leg support frame is provided with a fixing groove that cooperates with the supporting base rod. The reinforcing beams make the back support frame structure stable, and the fixing groove makes the leg support frame installation stable.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by working with the telescopic cylinder and cooperating with the hinge seat, the hip frame body is pushed to move and extend along the leg fixing frame. The connection handle mechanism allows the hip frame body to extend while pulling the back frame body, so that the back frame body can be adjusted in angle, making it more convenient for passengers to sit, reducing discomfort and relieving riding fatigue.

[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-speed rail seat motion frame, including a fixed back cover 1 and two supporting base rods 4 located below the fixed back cover 1. The fixed back cover 1 is provided with a back fixing frame 5. A back frame body 7 is movably fitted on the back fixing frame 5. A leg fixing frame 16 is fixed at the bottom of the back fixing frame 5. A hip frame body 8 is movably fitted at the top of the leg fixing frame 16.

[0021] The hip frame body 8 and the back frame body 7 are connected by a connecting handle mechanism;

[0022] A telescopic cylinder 12 is installed on the side of the hip frame body 8 near the connecting handle mechanism via a hinge seat 11. The output end of the telescopic cylinder 12 is connected to the side of the hip frame body 8 away from the connecting handle mechanism.

[0023] When the telescopic cylinder 12 pushes the hip frame body 8 to extend, the back frame body 7 adjusts its angle. Through the operation of the telescopic cylinder 12, in conjunction with the hinge seat 11, the hip frame body 8 is pushed to move and extend along the leg fixing frame 16. The connection handle mechanism allows the hip frame body 8 to extend while pulling the back frame body 7, thereby adjusting the angle of the back frame body 7 to facilitate passenger seating, reduce discomfort, and alleviate riding fatigue.

[0024] The telescopic cylinder 12 can be operated electrically or manually. When the telescopic cylinder 12 is operated electrically, the passenger sits on the seat, and the telescopic cylinder 12 pushes the hip frame body 8 to extend. At this time, the passenger does not need to pull the hip frame body 8. When the telescopic cylinder 12 is operated manually, the telescopic cylinder 12 is connected to the pull rod through the return spring. One end of the pull rod is connected to the hip frame body 8. When the seat needs to be adjusted, the passenger gets off the seat and manually pulls the hip frame body 8 to extend. Correspondingly, the seat is equipped with a buckle to lock the fully extended hip frame body 8. The buckle makes the adjusted hip frame body 8 stable. When the seat needs to be restored, the buckle is released, and the hip frame body 8 returns to the initial position under the restoring force of the return spring.

[0025] In a further embodiment, the connecting handle mechanism includes a first connecting handle 9 and a second connecting handle 10. The top of the first connecting handle 9 is fixedly connected to the bottom of the back skeleton body 7, one end of the second connecting handle 10 is fixedly connected to the adjacent hip skeleton body 8, and the other end of the second connecting handle 10 is hinged to the bottom of the first connecting handle 9. Through the mutual hinge of the first connecting handle 9 and the second connecting handle 10, when the hip skeleton body 8 is extended, the second connecting handle 10 pulls the first connecting handle 9, thereby pulling the back skeleton body 7.

[0026] In a further embodiment, the upper part of the back support frame 5 is symmetrically provided with guide inclined blocks 17, and the guide inclined blocks 17 are provided with moving grooves 18. The upper part of the back frame body 7 is provided with a connecting beam 19. The side of the connecting beam 19 facing the guide inclined blocks 17 is provided with a moving block 20 that slides in cooperation with the moving groove 18. When the telescopic cylinder 12 drives the back frame body 7 to adjust the angle, the moving block 20 slides in the moving groove 18. Through the sliding cooperation between the moving block 20 and the moving groove 18, the angle adjustment of the back frame body 7 is convenient while ensuring the stability of the angle adjustment of the back frame body 7.

[0027] In a further embodiment, a guide groove 14 is provided on one side of the leg fixing frame 16, and a guide plate 13 is fixed at the bottom of the hip frame body 8. The guide plate 13 is located in the guide groove 14. When the telescopic cylinder 12 pushes the hip frame body 8 to extend, the hip frame body 8 drives the guide plate 13 to slide in the guide groove 14. Through the cooperation between the guide plate 13 and the guide groove 14, it is convenient for the hip frame body 8 to extend while ensuring the stability of the hip frame body 8 when extending.

[0028] In a further embodiment, a limiting seat 15 is provided on the support base 4 located below the front end of the hip skeleton body 8. The limiting seat 15 limits the movement of the hip skeleton body 8, so that the hip skeleton body 8 moves stably.

[0029] In a further embodiment, the back support frame 5 is provided with several reinforcing beams 6, and the bottom of the leg support frame 16 is provided with a fixing groove that cooperates with the support base rod 4. The back support frame 5 is structurally stable by the setting of the reinforcing beams 6, and the leg support frame 16 is installed stably by the setting of the fixing groove.

[0030] Working principle: The telescopic cylinder 12 works in conjunction with the hinge seat 11 to push the hip frame body 8 to extend along the leg fixing frame 16. The guide plate 13 cooperates with the guide groove 14 to ensure the stability of the hip frame body 8 during extension. The connecting handle 10 and the connecting handle 20 are hinged to each other. When the hip frame body 8 extends, the connecting handle 20 pulls the connecting handle 19, which in turn pulls the back frame body 7, allowing the back frame body 7 to adjust its angle. The sliding cooperation between the moving block 20 and the moving groove 18 ensures the stability of the back frame body 7 angle adjustment, making it convenient for passengers to sit, reducing discomfort and relieving riding fatigue.
