[0020] Please also read Figures 1 to 6 , the lightweight cab structure and rail vehicle provided by the present invention are now described. The lightweight cab structure includes a cab cover 1 and a cab frame, the cab frame includes a chassis 2, a ring beam 3, two anti-collision beams 4 and a plurality of auxiliary beams 5, the ring beam 3 is connected to the top of the chassis 2 and connected to the front end of the vehicle body, the two anti-collision beams 4 are respectively connected to the front side of the chassis 2, and the anti-collision beams 4 extend backward and upward to connect to the ring beam 3, and the auxiliary beams 5 are connected between the two anti-collision beams 4 or between the anti-collision beam 4 and the ring beam 3.

[0021] Compared with the prior art, the lightweight driver's cab structure provided in the present embodiment comprises a frame structure formed by a base frame 2, a ring beam 3 and two anti-collision beams 4, and a stable driver's cab frame is formed in combination with the arrangement of multiple auxiliary beams 5. The driver's cab outer cover 1 is coated on the outside of the driver's cab frame, and the two form a stable driver's cab structure. The above-mentioned driver's cab structure is simple in structure and easy to install, meeting the requirements of lightweight design of the driver's cab, and is suitable for urban trains with different driver's cab shapes, having good versatility and wide applicability.

[0022] In this embodiment, two anti-collision beams 4 are respectively arranged near the left and right sides of the vehicle body, and the ring beam 3 is connected to the rear side of the anti-collision beam 4 and connected to the upper end of the anti-collision beam 4. The base frame 2, the ring beam 3 and the two anti-collision beams 4 form a frame structure, and the auxiliary beam 5 is used to connect two adjacent anti-collision beams 4 or adjacent anti-collision beams 4 and ring beams 3, so that the entire driver's cab frame has a stable structure, which helps to improve the support reliability of the structure and ensure effective support for the driver's room outer cover 1.

[0023] Specifically, the auxiliary beam 5 is connected to the middle position of the anti-collision beam 4 or the ring beam 3 in the height direction, and can form a connection with the driver's outer cover 1. The auxiliary beam 5 located between the two anti-collision beams 4 is convexly arranged toward the front side of the vehicle body, so as to support and connect the front part of the driver's outer cover 1, thereby ensuring the integrity and reliability of the structure.

[0024] On the basis of the above structure, the chassis 2 is made of alloy steel, and the ring beam 3, the anti-collision beam 4 and the auxiliary beam 5 are all made of carbon fiber.
