All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 12 , in the embodiment of the present invention, a turnout traveling guiding system 100 for a rail vehicle includes: a branch track 10 and a rail vehicle 20.

[0022] The branch track 10 includes: a main track 11, a turnout track 12, a main track guiding member 13, and a branch track guiding member 14. The main track guiding member 13 is used to guide the rail vehicle 20 to travel along the main track 11. The branch track guiding member 14 is used to guide the rail vehicle 20 to travel along the turnout track 12. The main track guiding member 13 extends along the main track 11. The branch track guiding member 14 extends along the turnout track 12. Specifically, a part of the branch track guiding member 14 is parallel to the main track guiding member 13, and another part of the branch track guiding member 14 gradually moves away from the main track guiding member 13.

[0023] As a specific implementation manner, guiding structures 16 are provided at the upstream of the traveling direction of the rail vehicle 20 on both the main track guiding member 13 and the branch track guiding member 14. The guiding structure 16 can be a guiding inclined surface or a guiding arc surface. Specifically, after the first guiding wheel 271 or the second guiding wheel 272 contacts the guiding structure 16, the first guiding wheel 271 or the second guiding wheel 272 will correct its position under the guidance of the guiding structure 16.

[0024] The rail vehicle 20 includes: a vehicle frame 21, a traveling drive device, and a track-changing device. The track-changing device is used to drive the rail vehicle 20 to travel along the main track 11 or along the turnout track 12. The track-changing device and the traveling drive device are mounted to the vehicle frame 21. The traveling drive device includes: a power motor 22 and traveling wheels 23. The power motor 22 drives the traveling wheels 23 to rotate so that the rail vehicle 20 travels. Specifically, compared with the traditional lane-changing method, the turnout traveling guiding system 100 of the rail vehicle adopts a track-changing device provided on the rail vehicle 20, and it is not necessary to provide a driving mechanism on the rail turnout to drive the turnout to move, and the lane change of the rail vehicle 20 can also be realized. More specifically, the structural setting of the track-changing device can guide the rail vehicle 20 to achieve a lane change, with a simple structure and low cost.

[0025] The track-changing device includes: a drive motor 24, a driving gear 25, a driven gear 26, and a swing arm assembly 27. The swing arm assembly 27 is rotatably mounted to the vehicle frame 21.

When in the turnout track traveling position, the second guide wheel 272 can abut against the turnout guide 14, and the turnout guide only cooperates with the second guide wheel 272 to guide the rail vehicle 20 to travel along the turnout track 12.

[0027] The drive motor 24 drives the driving gear 25 to rotate, driving the driven gear 26 to rotate, so that the swing arm assembly 27 rotates between the main track traveling position and the turnout track traveling position. Specifically, the drive motor 24 drives the swing arm assembly 27 to drive the first guide wheel 271 to rise and abut against the main track guide 13, while driving the second guide wheel 272 to descend and move away from the turnout guide 14, so that the rail vehicle 20 travels along the main track 11. The drive motor 24 drives the swing arm assembly 27 to drive the second guide wheel 272 to rise and abut against the turnout guide 14, while driving the first guide wheel 271 to descend and move away from the main track guide 13, so that the rail vehicle 20 travels along the turnout track 12. Thus, the lane change of the rail vehicle 20 is realized.

[0028] As a specific implementation manner, both the main track 11 and the turnout track 12 are provided with intermediate grooves 15.

The stabilizer wheels 28 are located within the intermediate groove 15. The number of the stabilizer wheels 28 is two. The two stabilizer wheels 28 are arranged along the traveling direction of the rail vehicle 20. Specifically, the structural setting of the stabilizer wheels 28 can assist the rail vehicle 20 to maintain stability and improve the stability and balance of the rail vehicle 20.

[0031] As a specific implementation manner, both the main track 11 and the turnout track 12 are annular structures closed on all sides.
