DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] In the description of the present invention, it should be noted that the directions or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0033] A seat for improving riding comfort in high-speed trains, such as Figure 1 , 2As shown in , 3, it includes a supporting mechanism 1, a seat cushion 2, a seat back 3 and a transmission mechanism 4; the supporting mechanism 1 is offset on one side of the seat base; the transmission mechanism 4 is directly installed on the supporting mechanism 1; the seat cushion 2 and the seat back 3 are cantilevered on the transmission mechanism 4 at the offset side of the supporting mechanism 1 through a sliding frame 5; the space below the seat cushion 2 is formed by the offset avoidance of the supporting mechanism 1, the seat cushion 2, the seat back 3 and the transmission mechanism 4 to form a leg hole accommodating space 6.

[0034] Specifically, the invention comprises a supporting mechanism 1, a seat cushion 2, a seat back 3 and a transmission mechanism 4; the supporting mechanism 1 is offsetly arranged on one side of the seat base; the transmission mechanism 4 is directly mounted on the supporting mechanism 1; the seat cushion 2 and the seat back 3 are cantilevered on the transmission mechanism 4 at the offset side of the supporting mechanism 1 through a sliding frame 5; the space below the seat cushion 2 is formed by the offset avoidance of the supporting mechanism 1, the seat cushion 2, the seat back 3 and the transmission mechanism 4 to form a leg hole accommodating space 6, and the transmission mechanism 4 itself is offsetly arranged in a highly integrated state, so that when the front and rear spacing remains unchanged, the leg hole accommodating space 6 is arranged at the rear of the seat, so that the passenger's calves and soles have space to be placed, so that the human body can be in a stretched state, thereby improving the riding comfort of the high-speed train, and because the front and rear spacing remains unchanged, the original train capacity will not be reduced, thereby ensuring the riding comfort and not reducing the train efficiency. The offset design of the supporting mechanism 1, the seat cushion 2, the seat back 3 and the transmission mechanism 4 maximizes the leg opening space 6 while maintaining the stability of the seat, thereby improving the comfort.

[0035] As a preferred embodiment of the above, Figure 3 As shown, the leg hole stepping space 6 is set within the range of 250-350 mm in width, 250-350 mm in height, and 250-400 mm in depth.

[0036] Specifically, by setting the leg hole stepping space 6 within the range of 250-350mm in width, 250-350mm in height, and 250-400mm in depth, and cooperating with the offset design of the supporting mechanism 1, the seat cushion 2, the seat back 3, and the transmission mechanism 4, it is possible to adaptively adjust the associated space range on the basis of improving the riding comfort of high-speed trains, thereby adjusting the specific number of seats, increasing the train capacity, and increasing economic benefits.

[0037] As a preferred embodiment of the above, Figure 3As shown, a rotary bearing 1-1 is installed in the seat base to enable the supporting mechanism 1 to rotate, and a rotary locking mechanism 1-2 positions and locks the supporting mechanism 1 and unlocks it through an unlocking foot pedal 1-3.

[0040] Specifically, the transmission mechanism mounting interfaces 1-4 are arranged on the supporting mechanism 1, and the transmission mechanism mounting interfaces 1-4 are concentrated inward to avoid the structure of the leg hole stepping space 6, so as to further realize the space expansion of the leg hole stepping space 6 and further improve the riding comfort of the high-speed train.

[0041] As a preferred embodiment of the above, Figure 4 , 5 As shown, the transmission mechanism mounting interface 1-4 is provided with a guide groove 1-4-1 and a buckle 1-4-2, the buckle 1-4-2 fixes the transmission mechanism 4 in the up and down directions, the guide groove 1-4-1 fixes the transmission mechanism 4 in the left and right directions, the transmission mechanism quick lock 1-4-3 fixes the transmission mechanism 4 in the front and back directions, and under the guidance of the guide groove 1-4-1, the electrical interface 1-4-4 is synchronously docked.

[0042] Specifically, a guide groove 1-4-1 and a buckle 1-4-2 are provided through the transmission mechanism installation interface 1-4, the buckle 1-4-2 fixes the transmission mechanism 4 in the up and down directions, the guide groove 1-4-1 fixes the transmission mechanism 4 in the left and right directions, and the transmission mechanism quick lock 1-4-3 fixes the transmission mechanism 4 in the front and back directions.

The transmission mechanism 4 can move along a preset path during the installation process to ensure the accuracy of the installation position. At the same time, the coordinated use of the buckle 1-4-2 and the transmission mechanism quick lock 1-4-3 can further ensure the tight connection between the transmission mechanism 4 and the supporting mechanism 1, improve the stability of the overall structure, and at the same time enable the electrical interface 1-4-4 to be docked synchronously, ensuring the accuracy and stability of the electrical connection, and the tight and accurate installation structure helps to reduce the noise and vibration generated by the seat system during operation, further improving the ride comfort of high-speed trains, and during maintenance, due to the limitations of space and maintenance time of high-speed trains, the seat main body part above the seat transmission mechanism can be directly disassembled and replaced as a whole, and the damaged parts can be taken outside the vehicle for repair.

The translation module integrates multiple functions such as the sliding frame interface 4-1, the backrest connecting rod interface 4-2, and the electrical matching interface 4-3, so that the structure of the entire seat system is more compact, integrated, and modular, and the number of components is reduced, and the complexity and maintenance difficulty are reduced. At the same time, the compactness is further improved, so that the space for the leg hole to accommodate the stepping space 6 can be further expanded, thereby further improving the riding comfort of the high-speed train.

The leg rest 7 has a structure that moves back and forth synchronously with the sliding frame 5, so that on the basis of having a large space leg hole accommodating space 6, the seat main body part above the seat transmission mechanism can be directly disassembled and replaced as a whole during maintenance, and the damaged parts can be taken out of the vehicle for maintenance. The movement of the sliding frame 5 can drive the seat cushion 2, the seat back 3 and the leg rest 7 to move forward and backward synchronously, ensuring that the various seat components can maintain a relative position relationship during adjustment, thereby providing a more stable and comfortable riding experience.
