[0030] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0031] See appendix Figures 1 to 8 This embodiment discloses a tractor cab with the tractor's forward direction as the front. The cab includes: a floor assembly 1, a first mudguard 2, a second mudguard 3, a first seat 4, and a second seat 6.

[0032] See appendix Figures 1 to 3 The floor assembly 1 serves as the floor of the cab, supporting the cab. The first mudguard 2 and the second mudguard 3 are symmetrically arranged on the left and right sides of the floor assembly 1 and are respectively located above the two rear wheels of the tractor. The first seat 4 is located at the rear of the floor assembly 1 and between the first mudguard 2 and the second mudguard 3. The first seat 4 serves as the main seat, and in front of the first seat 4 are operating components such as a steering wheel and a display screen. The main driver can control the tractor while sitting in the first seat 4.

[0033] See appendix Figures 3 to 6 The second seat 6 is a passenger seat, where the co-driver can assist the driver in observation and some operations. The second seat 6 includes a backrest 62 mounted on the first mudguard 2 and / or the second mudguard 3, and a seat cushion 61 rotatably positioned in front of the backrest 62. A folding device 63 is provided between the backrest 62 and the seat cushion 61, causing the upper surface of the seat cushion 61 to conform to the backrest 62 or have a tendency to rotate towards the backrest 62. In other words, in its natural state, the second seat 6 is folded down and does not affect the driver's entry and exit from the cab. In use, the driver unfolds the second seat 6, allowing the co-driver to sit in it.

[0034] See appendix Figure 3 The first seat 4 is a rotatable seat. There are various implementations of the rotatable seat structure, such as the one previously applied for by our company, with announcement number CN222157251U. When the driver needs to rest in the tractor cab, the second seat 6 can be opened and the first seat 4 rotated until the central axis of the first seat 4 is aligned with the second seat 6. At this time, the driver's body can lean back on the first seat 4, and his legs can be placed on the second seat 6, providing the driver with a more comfortable resting environment.

[0035] See appendix Figure 4 The central axis of the second seat 6 is at an angle of 5 to 15° with the central axis of the base plate assembly 1 in the horizontal direction, preferably 7 to 13°, and more preferably 10°. By rotating the second seat 6 toward the central axis of the base plate assembly 1, the co-driver sitting in the second seat 6 can better see the center mark of the hood and not have his / her vision blocked by the front pillar. Moreover, the co-driver's overall sitting posture is also shifted inward, and his / her maneuvering space is also greater.

[0036] See appendix Figure 5 The angle between the backrest 62 and the seat cushion 61 is 95-108°, preferably 100-105°, and more preferably 103°, so that the folded second seat 6 fits more closely to the first mudguard 2 and / or the second mudguard 3, making it easier for the driver to enter and exit the cab. Moreover, the tilting setting of the backrest 62 makes the entire second seat 6 more ergonomic and improves the comfort of using the second seat 6.

[0037] See appendix Figure 4 The backrest 62 is fixedly mounted on the first mudguard 2 and / or the second mudguard 3 via the mounting base 5. Preferably, the second seat 6 is disposed on the first mudguard 2, which is located on the left side. An operating unit is provided on the second mudguard 3, resulting in a more reasonable overall spatial arrangement. The bottom contour of the mounting base 5 is adapted to the contour of the first mudguard 2 and connected together by welding. The mounting base 5 and the first mudguard 2 are fixed together by bolts.

[0038] See appendix Figure 7 , 8The backrest 62 includes a main frame 621 mounted on the mounting base 5 and a cushion body 622 mounted on the main frame 621. The main frame 621 is a sheet metal part and includes an integrally formed mounting part 6211, a transition part 6212, a support part 6213, and a backrest 6214. The mounting part 6211 is mounted on the mounting base 5 and extends upward to form the transition part 6212. The support part 6213 is connected to the transition part 6212 and is horizontally arranged. The backrest 6214 is inclinedly arranged on the mounting part 6211, and the cushion body 622 covers the backrest 6214. In addition, reinforcing ribs 6215 are provided between the transition part 6212 and the support part 6213, and between the transition part 6212 and the mounting part 6211 to ensure the structural stability of the entire main frame 621.

[0039] See appendix Figure 7 The upper end of the support part 6213 is provided with a first bending part 6217 and a second bending part 6218. A pivot 631 is provided between the first bending part 6217 and the second bending part 6218. An elastic element 632 is sleeved on the pivot 631. A connecting member 611 is provided at the rear end of the seat cushion 61. One end of the elastic element 632 is connected to the pivot 631, and the other end of the elastic element 632 is connected to the connecting member 611, so as to realize the rotational connection between the seat cushion 61 and the backrest 62. The elastic element 632 is a storage spring, so that the second seat 6 is in a folded state in the natural state.

[0040] See appendix Figure 7 , 8 A limiting block 6216 is provided on the support part 6213. The limiting block 6216 is aligned with the connecting member 611. When the second seat 6 is in the open state, the seat cushion 61 is in the horizontal direction. The limiting block 6216 abuts against the connecting member 611 to prevent the seat cushion 61 from overturning and improve the support capacity of the second seat 6.

[0041] See appendix Figure 5 The width of the front portion of the seat cushion 61 is greater than the width of the support portion 6213, and clearance portions 612 are provided on both sides of the rear portion of the seat cushion 61. On the one hand, the front portion of the seat cushion 61 has a larger support surface, which can improve the comfort of the second seat 6. On the other hand, since the area between the first seat 4 and the first mudguard 2 and the second mudguard 3 is provided with control elements such as the clutch lever, PTO lever, gear lever, and throttle lever, the clearance portions 612 formed in the rear portion of the seat cushion 61 can prevent the seat cushion 61 from physically interfering with the control elements near the second seat 6 during the flipping process.

[0042] See appendix Figure 5The first bend 6217 is equipped with a seatbelt retractor 64a, and the second bend 6218 is equipped with a seatbelt buckle 64b. A first end cap 65a is also provided on the outer side of the first bend 6217, and a second end cap 65b is provided on the outer side of the second bend 6218, serving a protective function. The seatbelt retractor 64a and seatbelt buckle 64b are located within the clearance portion 612, ensuring that the seat cushion 61 and backrest 62 are in a fully folded, close-fitting state.

[0043] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
