When the telescopic rod 50 is in a retracted state, the front wheel is located in the groove 105. Through the above design, the front baffle 103 can effectively resist the splashing sewage and mud generated when the front wheel 90 rolls. At the same time, the design of the groove 105 can facilitate the storage of the front wheel 90, reduce the space occupied by the entire electric luggage case, and improve the overall aesthetics of the electric luggage case. The slide rail 40 is integrally formed with the front baffle 103 and communicated with the socket 104. One end of the electric push rod 60 is connected and fixed to the inside of the box body 10, and the other end is connected and fixed to the telescopic rod 50, which is used to provide power for the sliding of the telescopic rod 50.

[0032] Preferably, the front baffle 103 is made of plastic material, which reduces the overall weight of the electric luggage while ensuring the overall structural strength of the electric luggage, so that it is more convenient to carry. In addition, the electric luggage provided by the present application can also reduce the overall size of the electric luggage without changing the overall structure, and reduce the weight to meet the boarding requirements.

[0033] See also Figure 2 The front handle bar 80 includes a fixed bar 806 and a lifting bar 807. The front wheel 90 is installed at the bottom of the fixed bar 806. The lower part of the fixed bar 806 is rotatably connected to the front end of the telescopic bar 50. The steering gear 801 is fixedly installed on the inner wall of the fixed bar 806. The lifting bar 807 is slidably installed on the upper part of the fixed bar 806 and can slide up and down along the fixed bar 806 and be positioned and fixed. When the lifting bar 807 rotates, it drives the fixed bar 806 and the front wheel 90 to rotate to achieve steering. The lifting bar 807 can be lifted up and down along the fixed bar 806 and positioned and fixed in a manner of a lock. The user can loosen and tighten the lifting bar 807 by pulling the folding handle; it can also be a buckle. The user can drive the buckle to disengage from the limit hole by pressing the lifting button, and the lifting bar 807 can be lifted and slid. When the buckle is embedded in the limit hole, the lifting bar 807 is positioned and fixed. This application does not specifically limit the lifting and lowering and positioning and fixing of the lifting bar 807.

[0034] Through the above design, the user can adjust the height of the lifting rod 807 to achieve an optimal riding posture, thereby improving the user's experience.

[0035] See also Figure 2 and Figure 3, pedals 901 are provided on both sides of the front wheel 90, which can provide foot support for the user when riding, so as to improve the riding comfort of the user; a rear handle bar 106 is provided at the rear of the box body 10, and the user can choose to ride the suitcase and push and pull the suitcase. When the user does not want to ride, the rear handle bar 106 is pulled out to push and pull the suitcase; a power switch 107 and a control switch 108 for controlling the extension and retraction of the telescopic rod are provided on the side of the box body 10, and the power switch 107 and the control switch 108 are both connected to the controller 30. Through the above design, the power switch 107 and the control switch 108 can realize the automatic control of the electric suitcase, greatly improving the user experience.

[0036] See also Figure 1 and Fig.12 The use process of the smart electric suitcase provided by the present application is as follows: when the user chooses to ride the electric suitcase, the power switch 107 is turned on, and the control switch 108 is operated to control the electric push rod 60 to extend outward, and push the telescopic rod 50, the front handle bar 80 and the front wheel 90 to extend outward. At this time, the user can freely adjust the extension length of the telescopic rod 50. After the telescopic rod 50 is extended, the user sits on the upper part of the box body 10 and places both feet on the pedals 901. The electric suitcase can be moved forward or backward by manually operating the control component 803, and the electric can be realized by rotating the front handle bar 80. Steering of the luggage case; in the electric steering mode, the steering driver 501 is controlled by the controller 30 to rotate forward or reverse, and the coupling 502 and the driving gear 504 drive the steering gear 801 to rotate, so as to realize the left and right steering of the front handle bar 80; when the user chooses to push or pull the electric luggage case, the control switch 108 is operated to control the electric push rod 60 to retract inward, and pull the telescopic rod 50, the front handle bar 80 and the front wheel 90 to retract inward, at which time the front wheel 90 is stored in the groove 105, and then the power switch 107 is turned off, and the rear handle bar 106 is pulled out, and the electric luggage case can be pushed or pulled.
