[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] The following describes the present utility model in detail with reference to the drawings and embodiments.

[0024] The high-speed rail conference chair, as Figure 1 shown, includes a seat 1 and a backrest 2. The seat 1 includes a seat cushion 3 and chair legs 4. Specifically, both the seat cushion 3 and the backrest 2 can be made of memory foam. The memory foam can provide good support and softness, ensuring the comfort of the conference chair. The surfaces of the seat cushion 3 and the backrest 2 are provided with leather layers. The leather surface is easy to clean and maintain, and has good resistance to stains and wear. The chair legs 4 are made of stainless steel material. The stainless steel material has the characteristic of high strength, ensuring the strength of the chair legs 4 made thereof, and thus guaranteeing the stability and safety of the conference chair during use.

[0025] A tray mechanism 5 is provided between the seat cushion 3 and the backrest 2. The tray mechanism 5 has an open state and a closed state. When the tray mechanism 5 is in the open state, the included angle formed between the backrest 2 and the seat cushion 3 is 105°. When the tray mechanism 5 is in the closed state, the included angle formed between the backrest 2 and the seat cushion 3 is 98°. When people are in a meeting and sit upright, the tray mechanism 5 is in the closed state at this time, making the backrest 2 set vertically, which better conforms to the back curve of people, helps to maintain the correct sitting posture, and reduces back fatigue. When people are resting, they can lean on the backrest 2. At this time, the tray mechanism 5 rotates and is in the open state. The 105° included angle is more in line with the ergonomic design, allowing passengers to lean on the backrest 2 in a more relaxed posture, which helps to relieve the body tension caused by sitting for a long time. At the same time, during the meeting process, this design allows pedestrians to pass through from behind the backrest 2, so that it can meet the use in a narrow space. By setting the tray mechanism 5, people can adjust the included angle between the backrest 2 and the seat cushion 3 according to personal needs and comfort when using the meeting chair. In a narrow space such as a high-speed rail, the design that can flexibly adjust the angle of the seat 1 can maximize the use of the limited space and provide a more comfortable riding experience.

[0026] Specifically, the tray mechanism 5 includes a fixed disk 6 and a rotating disk 7. A rotating shaft 8 is provided on the fixed disk 6, and the rotating disk 7 is rotatably connected to the fixed disk 6. Two torsion springs 9 are provided between the fixed disk 6 and the rotating disk 7, and both ends of each torsion spring 9 respectively abut against the fixed disk 6 and the rotating disk 7. The design of the fixed disk 6 and the rotating disk 7, combined with the use of the torsion springs 9, can provide stable support to ensure the stability of the seat 1 when adjusting the angle. The use of the torsion springs 9 provides elastic support, allowing the backrest 2 to be finely adjusted within a certain range. The rotating disk 7 is rotatably connected to the fixed disk 6 through the rotating shaft 8, ensuring the smoothness and accuracy of the rotation process and improving the use experience. Further, both torsion springs 9 are sleeved on the rotating shaft 8, and the ends of the two torsion springs 9 close to the rotating disk 7 abut against each other. The setting of the two torsion springs 9 helps to balance the force, so that the backrest 2 can remain stable at different angles and reduce the shaking of the seat 1 caused by uneven force. At the same time, the design of the torsion springs 9 and the rotating shaft 8 simplifies the internal structure of the tray mechanism 5, reduces the manufacturing cost, and is also convenient for maintenance and cleaning.

[0027] Furthermore, a number of mounting holes 10 are provided on both the fixed disk 6 and the rotating disk 7. The fixed disk 6 is fixed to the seat cushion 3 by bolts, and the backrest 2 is fixed to the rotating disk 7 by bolts. When the tray mechanism 5 is in the open state, the torsion spring 9 is in a compressed state. When the tray mechanism 5 is in the closed state, the torsion spring 9 is in its original state. The design of the mounting holes 10 makes the installation of the fixed disk 6 and the rotating disk 7 more convenient and standardized, facilitating rapid assembly and disassembly. The design of the bolts also ensures the connection strength between the seat cushion 3, the backrest 2, and the tray mechanism 5. The torsion spring 9 is in its original state when the tray mechanism 5 is in the closed state, which helps to restore force and ensures that when the conference chair is not in use, the backrest 2 can quickly and stably return to the vertical position.

[0028] Two symmetrically arranged plastic armrests 11 are provided on the seat cushion 3. Specifically, the height of the plastic armrest 11 from the ground is less than 640 millimeters. When the conference chair is not in use, people can drag the conference chair under the table, thus expanding the space inside the carriage and keeping the carriage space clean and tidy. The armrests provide additional support points for passengers, which can relieve the fatigue of the arms and shoulders and make the riding experience more comfortable. At the same time, the symmetric armrest design helps passengers maintain balance when getting up or sitting down, especially on high-speed trains. Moreover, the plastic material usually has good durability and wear resistance, extending the service life of the armrests and reducing the maintenance cost of the conference chair.

[0029] The above description is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
