In addition, the back of the box 1 is provided with four small universal wheels 14, a luggage lock 15, and a brake light 6 connected to the main control circuit board through a wire, and the brake light 6 is roughly located in the middle of the back of the box 1, and the height of the brake light 6 is not higher than the height of the universal wheel. When the electric mode is not needed, the electric suitcase can be flipped back 90 degrees so that the back is in contact with the ground, and the operating lever 4 on the top of the box 1 can be pulled or pushed by hand. A small storage bag 12 for placing small items is also provided on the other side of the box body 1 (the opposite side to the battery pack 2). The small storage bag 12 can be sealed by a zipper and can hold some small items, such as mobile phones, data cables, headphones, etc.

[0033] Specific, with reference Figures 9 to 11As shown, the folding pedal 3 is connected to the inner groove surface of the storage groove by a pin shaft to form a rotational connection. After being retracted, it does not protrude from the outer side of the box body 1. The folding pedal 3 includes a first pedal 31 and a second pedal 32 connected to each other. The second pedal 32 is reciprocated or extended along the length direction of the first pedal 31, so that the second pedal 32 is retracted inside the first pedal 31, or extended to increase the overall length of the folding pedal 3. Among them, the first pedal 31 can be set to be a rectangular groove with an opening on the top, and a slide groove is set on the inner side or bottom of the groove of the groove-shaped first pedal 31. The width of the second pedal 32 is smaller than the width of the first pedal 31. The second pedal 32 can be rectangular or flat. The outer edge of the second pedal 32 can slide back and forth along the slide groove to change the length of the entire folding pedal 3, which is more comfortable for users to put their feet. When it needs to be stored, the second pedal 32 is first retracted inward into the first pedal 31, and then the first pedal 31 is rotated upward ninety degrees and stored in the storage groove opened on the side of the box body 1. It is extremely convenient to use and also reduces the length space of the storage groove.

[0034] In this embodiment, a hand-held operating lever 4 is provided at the front position of the top of the box body 1. The operating lever 4 is provided on the left and right sides, which is convenient for the left and right hands to hold and control the driving direction. The left and right operating levers 4 are provided with a forward button 41 and a brake button 42, wherein the forward button 41 and the brake button 42 are connected to the main control circuit board through a signal line. When moving forward, the forward button 41 is pressed to give a forward instruction to the main control circuit board, and the main control circuit board drives the driving motor of the electric scooter to rotate in the set forward direction, driving the box body 1 and the user forward. When braking or reversing is required, the brake button 42 is pressed. At this time, a braking instruction is given to the main control circuit board, and the brake indicator light on the back of the box body 1 lights up. When the main control circuit board detects that the braking instruction time exceeds the preset time threshold during the stationary vehicle, it is determined to be a reversing mode. At this time, the driving motor is controlled to rotate in the opposite direction, and the electric luggage box is in the reversing mode. The brake light 6 at the rear of the vehicle is also lit during the reversing. Among them, the electric scooter can adopt the three-wheeled electric scooter commonly used in the prior art, and its structure and working principle are not repeated here.

[0035] In this embodiment, the battery pack 2 is a power bank. In order to facilitate the storage of the power bank, a groove-shaped storage slot is provided on one side of the box body 1. The power bank is clamped in the storage slot. The power bank will serve as the power source of the electric scooter and provide power for it. The power bank is provided with a USB interface and a Type-C interface, which is convenient for users to charge the power bank and power mobile devices. The battery pack 2 is also provided with a main power switch.

[0036] Reference Figure 6 to Figure 8As shown, in one embodiment of the present application, the two rear wheels 9 of the electric scooter are connected by a horizontal roller shaft 8, and the roller shaft 8 is provided with a shock absorber 5 connected to the bottom of the box body 1, wherein the shock absorber 5 includes a fixing seat 7, and a horizontal through hole 73 is provided on the upper part of the fixing seat 7, and the roller shaft 8 passes through the horizontal through hole 73 to connect the rear wheels 9 on the left and right sides, and the rear wheels 9 are connected to the roller shaft 8 through a bearing, and the front and rear wheels 9 are not in contact with the bottom plate of the box body 1, and two vertical through holes 74 for the equal height screws 72 to pass through are provided on the fixing seat 7 on the front and rear sides of the horizontal through hole 73, wherein one end of the equal height screw 72 is fixed in the vertical through hole 74, and the other end (the end with the threaded surface) is connected to the bottom of the suitcase, so that the connection between the shock absorber 5 and the box body 1 is realized, and the outer part of the equal height screw 72 is covered with a retractable elastic component 71, and the elastic component 71 can be a spring or a rubber sleeve. The lower end of the elastic member 71 is fixed in the vertical through hole 74, that is, fixed on a circular table 79 of the fixing seat 7, and the upper end is a free end, which is not connected to the bottom of the box body 1. When the suitcase or scooter is compressed downward by pressure or gravity, the pressure will be transmitted to the wheels, and the fixing seat 7 connected to the wheels through the roller shaft 8 drives the spring to compress to form a shock absorbing effect.

[0037] The fixing seat 7 is divided into two groups, which are respectively close to the two rear wheels 9. A shock-absorbing plate is also provided on the upper and lower sides of the bottom of the suitcase, namely a first shock-absorbing plate 75 located above the bottom of the suitcase and a second shock-absorbing plate 76 located below the bottom of the suitcase. The elastic component 71 is located below the second shock-absorbing plate 76. The equal-height screws 72 pass through the lower second shock-absorbing plate 76, the bottom of the suitcase and the upper first shock-absorbing plate 75, respectively, and then are locked with nuts 77. The first shock-absorbing plate 75 and the second shock-absorbing plate 76 are respectively fixed to the upper and lower sides of the bottom surface of the suitcase. By providing at least one shock-absorbing plate, the buffering force of the suitcase during the downward pressure process is guaranteed. The two shock-absorbing plates are both a whole piece, and both can be made of rubber material or composite pearl cotton and other materials. When the road surface is bumpy, since the roller is not directly connected to the trolley case, but indirectly through the shock absorber 5 with a telescopic function, the shock absorber 5 reduces the force transmitted to the inside of the suitcase, the electric balance car, and the scooter.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
