[0023] The following combines the drawings to make a more detailed description of the above and other technical features and advantages of the present utility model.

[0024] Embodiment 1

[0025] This embodiment provides an electric suitcase, as Figure 1 shown, including a box body 1, a traveling assembly 2, a handle 3, a lifting rod assembly 4, and a telescopic footrest assembly 5. The traveling assembly 2 is arranged at the bottom of the box body 1 and is used to drive the box body 1 to move automatically. The lifting rod assembly 4 is arranged on the box body 1, specifically at the front position in the advancing direction of the box body 1. The handle 3 is arranged on the lifting rod assembly 4, and the height of the handle 3 can be adjusted through the lifting rod assembly 4, which is convenient for pulling the suitcase to move. A base 6 is arranged at the bottom of the box body 1, and the telescopic footrest assembly 5 can be stored in the base 6.

[0026] In the electric suitcase of this embodiment, when in use, the suitcase is driven to move through the traveling assembly 2, the height of the handle is adjusted through the lifting rod assembly, and the telescopic footrest assembly realizes the retraction and extension of the footrest, which is convenient for use, reduces the burden on the user, and improves the convenience of traveling.

[0027] As Figures 4 to 7 shown, the lifting rod assembly 4 includes a rod tube 41, a lead screw 42, and a lifting reduction motor 44. The rod tube 41 includes an outer tube part 411 and an inner tube part 412 slidably arranged in the inner cavity of the outer tube part 411. The upper end of the inner tube part of the rod tube 41 is connected to the handle 3. The lead screw 42 is arranged in the rod tube 41, and the inner tube part of the rod tube 41 is threadedly connected to the lead screw. Specifically, a threaded block is fixed at the lower end of the inner tube part of the rod tube 41, and the threaded block is threadedly connected to the lead screw 42. The lifting reduction motor 44 is connected to the lead screw 42 through a coupling 45. The lifting reduction motor 44 is arranged on a motor fixing seat 46, and the motor fixing seat 46 is arranged on the box body 1.

[0028] The outer tube portion 411 of the pull rod tube 41 is provided with an oblong hole, and the oblong hole is arranged vertically along the outer tube portion 411. A travel block 43 is fixed to the inner tube portion of the pull rod tube 41, and the travel block 43 is located within the oblong hole. A limit switch 47 is provided above and below the oblong hole respectively. When the travel block 43 moves close to the corresponding limit switch 47, the corresponding limit switch 47 can be triggered to stop the operation of the lifting and decelerating motor 44, thereby avoiding the inner tube portion exceeding the maximum travel distance.

[0029] Thus, the movement range of the travel block 43 can be restricted by the two limit switches 47. In this embodiment, the movement distance of the travel block 43 is 180 mm.

[0030] It should be noted that: a storage battery 7 and an intelligent control panel are provided on one side of the box body 1. The storage battery 7 is used to supply power to all the electrical appliances of the luggage, and the intelligent control panel can be used to display the status of the luggage, such as the power of the storage battery 7, etc.

[0031] Embodiment 2

[0032] This embodiment provides an electric luggage. As Figure 8 shown, on the basis of Embodiment 1, the telescopic footrest assembly 5 includes a telescopic bottom plate 51, a telescopic plate 52, a pedal upper cover 53, and a telescopic decelerating motor 54.
