Abstract

The present application relates to an axle structure and a vehicle. The vehicle includes a chassis, and the axle structure is arranged on the chassis. The axle structure includes a pedestal, a pivot shaft, an axle and limiting structures. The pivot shaft is fixed to the pedestal. The middle of the axle is rotatably connected to the pivot shaft, so that two ends of the axle can rotate vertically relative to the pedestal. In the axle structure provided in the present disclosure, the pivot shaft is provided on the pedestal, and the axle is rotatably connected to the pivot shaft.

Claims (26)

1. An axle structure, comprising:

a pedestal;

7. The axle structure according to claim 1 , wherein a reinforcing structure is provided in the middle of the axle, the thickness of the middle of the reinforcing structure is greater than that at two ends thereof, and a connection hole for connecting to the pivot shaft is formed in the reinforcing structure.

8. The axle structure according to claim 1 , wherein baffle are provided on the pivot shaft, and the baffle are located between the axle and the pedestal.

9. The axle structure according to claim 1 , further comprising a base, wherein guide posts are provided on the base, the pedestal is slidably connected to the guide posts, and a buffer member is provided between the base and the pedestal.

10. The axle structure according to claim 1 , wherein an accommodating cavity is provided in the axle, and cables for connecting to drive motors of a vehicle are routed through the accommodating cavity.

11. A vehicle, comprising an axle structure, a chassis, the axle structure is arranged on the chassis comprising an axle structure, the axle structure comprises a pedestal; a pivot shaft, disposed on the pedestal; and an axle, wherein a middle of the axle is rotatably connected to the pivot shaft, allowing two ends of the axle to rotate vertically relative to the pedestal; wherein the pivot shaft comprises an intermediate section and connecting sections connected to two ends of the intermediate section, a diameter of the intermediate section is greater than a diameter of the connecting section, and the middle of the axle is rotatably connected to the intermediate section.

12. The vehicle according to claim 11 , wherein the limiting structures are provided on the pedestal, and the limiting structures are configured to limit a rotating angle of the axle.

13. The vehicle according to claim 12 , wherein the limiting structures are configured as a chamfer structures disposed on the pedestal, and the axle comprises abutment surfaces mating with the chamfer structures.

14. The vehicle according to claim 11 , wherein the pedestal comprises a bottom plate and two side plates connected to the bottom plate, the two side plates are disposed opposite each other, and the pivot shaft is located between the two side plates; and

mounting grooves are formed on sides of the side plates facing away from the bottom plate, the pivot shaft is positioned in the mounting grooves, and the pivot shaft is connected to the side plates via fasteners.

15. The vehicle according to claim 11 , wherein the axle is bent outward at a position thereon corresponding to the pedestal to form an arched structure.

16. The vehicle according to claim 11 , wherein the axle comprises a first subsection and two second subsections connected to two ends of the first subsection; the first subsection is rotatably connected to the pivot shaft; and each of the second subsections is bent relative to the first subsection.

17. The vehicle according to claim 11 , wherein a reinforcing structure is provided in the middle of the axle, the thickness of the middle of the reinforcing structure is greater than that at two ends thereof, and a connection hole for connecting to the pivot shaft is formed in the reinforcing structure.

18. The vehicle according to claim 11 , wherein baffle are provided on the pivot shaft, and the baffle are located between the axle and the pedestal.

19. The vehicle according to claim 11 , further comprising a base, wherein guide posts are provided on the base, the pedestal is slidably connected to the guide posts, and a buffer member is provided between the base and the pedestal.

20. The vehicle according to claim 11 , wherein an accommodating cavity is provided in the axle, and cables for connecting to drive motors of a vehicle are routed through the accommodating cavity.
