[0062] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] First, it should be noted that the horizontal direction of the compartment 1 in the text refers to the width of the compartment, and the vertical direction of the compartment 1 refers to the height of the compartment.

[0064] This utility model embodiment discloses a business vehicle compartment, as shown in the attached figure. Figures 1 to 3 As shown, the vehicle includes a compartment 1, two rows of side cabinets 2, and two rows of seats 3. The two rows of side cabinets 2 are located on both sides of the compartment 1, with each row of side cabinets 2 flush against the side wall of the compartment 1. A corridor 11 is formed in the center of the compartment 1, and the two rows of seats 3 are located on both sides of the corridor 11. Each row of side cabinets 2 forms several independent compartments 4, and each seat group 3 includes several seats 31 distributed along the corridor 11 and rotating relative to the corridor 11. Each compartment 4 has one seat 31.

[0065] In a preferred embodiment, all seats 31 in the two rows of seating groups 3 are arranged one-to-one with the corridor 11 as the center. Each row of side cabinets 2 has four compartments 4, and each row of seating groups 3 has four seats 31. (See attached...) Figure 18 and 19 As shown, each seat 31 includes a seat cushion 312, a backrest 313, a cover 314, and a footrest 315, with the seat cushion 312 and footrest 315 integrally connected. When the seat cushion 312 and the backrest 313 are angled, the seat 31 is in a sitting or semi-reclined position; when the seat cushion 312 and the backrest 313 are flush, the seat 31 is in a fully reclined position. The cover 314 is fixed to the back of the backrest 313, and its two sides extend beyond the backrest 313 to form a partition. The partition is arc-shaped and bends inward toward the seat 31, so that the cover 314 covers the passenger's head in a wrapping manner, ensuring the privacy of the seat 31.

[0066] When seat 31 is rotated to the first position, as shown in the attached... Figure 1 As shown, all seats 31 in the two rows of seats 3 face the compartment 4, i.e., their backs are to the corridor 11. At this time, the seats 31 on both sides of the corridor 11 are angled, ensuring that each seat 31 is independent and does not interfere with others, providing good privacy, as divided by the compartment 4. When the seats 31 are rotated to the second position, as shown in the attached diagram... Figure 2As shown, all seats 31 of the two rows of seats 3 face the corridor 11, so that all seats 31 of the two rows of seats 3 are opposite each other, that is, the seats 31 on both sides of the corridor 11 are opposite each other, which facilitates communication between passengers and provides a better experience.

[0067] Therefore, this utility model provides seats 31 that rotate relative to the corridor 11 in each compartment 4. By adjusting the rotation angle of the seats 31, it meets the travel needs of different passengers and simultaneously enhances the privacy and experience of the business class carriage.

[0068] As attached Figure 20 As shown, each seat 31 is provided with a chassis 5 between it and the bottom plate of the compartment 1.

A rear receiving cavity 223 is formed on the side of the rear cabinet body 222 facing the seat 31. A rear footrest 315 plate 224 is slidably installed in the rear receiving cavity 223. When the seat 31 is in a reclined position, the seat 31 is flush with the rear footrest 315 plate 224, which supports the passenger's feet and enhances the comfort of the seat 31.

[0074] Both the front panel 211 and the rear panel 221 have a display screen 24 on the side facing the seat 31. The display screen 24 rotates vertically around the body 1, i.e., rotates left and right, so that the viewing angle of the display screen 24 is adapted to the rotation of the seat 31, thereby improving the viewing comfort of passengers. As a preferred embodiment, both the front panel 211 and the rear panel 221 have an embedding groove on the side facing the seat 31. A hinge is pivotally connected to one side of the embedding groove. The hinge is connected to the display screen 24 and is used to support the rotation of the display screen 24 around the hinge to adjust the viewing angle of the display screen 24.

[0075] As attached Figures 6 to 8 As shown, the center of the middle side cabinet 23 has a partition protrusion 231, which extends laterally from the compartment 1 towards the corridor 11 to separate two adjacent compartments 4, ensuring good privacy for the two adjacent compartments 4. The heights of the middle side cabinet 23, the front cabinet 212, and the rear cabinet 222 are approximately equal, ensuring that the passenger's line of sight can be fully folded when seated. The middle side cabinet 23 includes a first side 232 and a second side 233 symmetrically arranged around the partition protrusion 231, used to enclose the two adjacent compartments 4. When the seat 31 is rotated to the first position, the second side 233 is opposite to the seat 31.

[0076] As attached Figure 4 and 5As shown, both the front cabinet 212 and the rear cabinet 222 are L-shaped. The front cabinet 212 has a front side 217 on the side facing the seat 31, and the rear cabinet 222 has a rear side 225 on the side facing the seat 31. The front side 217 and the first side 232, the first side 232 and the second side 233, and the second side 233 and the rear side 225 are all smoothly connected to form arc-shaped sides, which avoids interference between the seat 31 and the side cabinet 2 when it rotates, and makes full use of the interior space of the carriage.

[0077] As attached Figure 6 As shown, a central receiving cavity 234 is formed within the central side cabinet 23, and a central footrest 235 is slidably provided on the side of the central receiving cavity 234 facing the second side 233; when the seat 31 is in the first position in a reclining state, the seat 31 is flush with the central footrest 235, as shown in the attached figure. Figure 13 As shown, the middle footrest 235 is used to support the passenger's feet and improve the comfort of the seat 31.

[0078] As attached Figure 9 As shown, the sides of the front footrest 216, the rear footrest 315, the middle footrest 224, and the middle footrest 235 are all fixed to the T-shaped slider 2351. The T-shaped slider 2351 and the fixed T-shaped slide rail 2352 can slide together to guide the three parts to slide and adjust their positions to meet the needs of passengers of different heights and improve passenger comfort.

[0079] As attached Figures 4 to 6 As shown, the tops of the middle side cabinet 23, the front cabinet 212, and the rear cabinet 222 are all equipped with storage slots 25 for placing items such as water cups, preventing items from falling and improving safety. The storage slots 25 are all fan-shaped, but are not limited to this design.

[0080] As attached Figure 10 As shown, a support rod 236 is rotatably provided on the spacer protrusion 231, and the support rod 236 rotates vertically around the body 1; a mounting bracket 237 is fixed on the top of the support rod 236; a display screen 24 is provided on the side of the mounting bracket 237 facing the seat 31; the display screen 24 rotates horizontally around the body 1 to adjust the viewing angle of the display screen 24 up and down, so as to meet the viewing needs of passengers sitting upright, reclining, or lying flat, and improve the comfort of watching movies.

[0081] The mounting bracket 237 has an electrical socket 26 on the side facing the seat 31; both the front panel 211 and the rear panel 221 have electrical sockets 26 and magazine racks 27 on the side facing the seat 31. The electrical socket 26 is used to charge electronic devices such as mobile phones, tablets or computers, and the magazine rack 27 is used to store magazines or newspapers, enriching the function of the side cabinet 2, meeting the needs of various passengers, and providing a better experience.

[0082] As attached Figure 7 and8 As shown, one of the first side 232 and the second side 233 is provided with a pleated door 238. The pleated door 238 is slidable and is used to selectively close the first side 232 and the second side 233. The position of the pleated door 238 can be flexibly adjusted according to the position of the seat 31. Specifically, when the seat 31 is opposite to the second side 233, the pleated door 238 covers the first side 232. When the seat 31 is opposite to the first side 232, the pleated door 238 covers the second side 233. In this way, the pleated door 238 can both separate the two adjacent compartments 4 and prevent the feet inside the middle side cabinet 23 from being exposed, making the interior space of the carriage cleaner and more private.

[0083] As attached Figure 13 As shown, the partition 4 has an entrance / exit on the side facing the corridor 11, and a roller 28 is provided on one side of the entrance / exit.
