Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0019] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] In this embodiment: Reference Figures 1-3 As shown, a preferred embodiment of the present invention is provided.

[0021] The electric folding luggage cover of this embodiment comprises a box body 1, a cover plate 2 and an inner compartment 3 disposed between the box body 1 and the cover plate 2. The box body 1 and the bottom of the cover plate 2 are connected by two sets of hinges 12. A support plate 21 is disposed on the top of the cover plate 2. A switching assembly 13 and a switch motor 14 are disposed on the inner sides of the bottom of the box body 1 and the cover plate 2. The cover plate 2 drives the hinge 12 to open and close in front of the box body 1 through the switch motor 14, and the inner compartment 3 is driven to rise and fall at the top and inside of the box body 1 and the cover plate 2 through the switch motor 14. The switching component 13 is used to switch the opening and closing of the cover plate 2 and the lifting and lowering operation of the inner compartment 3.

[0022] The box body 1 is also provided with a back panel 15 and a control device 16. The control device 16 includes a PLC and a power supply. The PLC is electrically connected to the switching component 13 and the switch motor 14, and the PLC is integrated with a Bluetooth module. The model of the PLC is S4-400. The switching component 13 and the switch motor 14 are powered by the power supply of the control device 16, and instructions can be sent to the PLC by using the Bluetooth function of the terminal to control the suitcase in real time.

[0023] See attached Figures 4-5 As shown, side rails 11 are provided on the inner walls of both sides of the box body 1, and the internal bearings of the side rails 11 are connected to guide rods 111. A transmission rod 112 is also connected between the bottoms of the two side rails 11 through bearings, and the two ends of the transmission rod 112 are meshed with the two guide rods 111 through helical gears for transmission.

[0024] In the attached Figures 6-7 In the embodiment, the switching assembly 13 is provided with an electromagnetic component 137 inside, and an armature 135 is telescopically provided inside the electromagnetic component 137. The end of the armature 135 is connected to a telescopic rod 131 extending to the outside of the end of the switching assembly 13 through a bearing. A spring 136 is further provided between the electromagnetic component 137 and one end of the telescopic rod 131 located inside the switching assembly 13. The external threads of the two guide rods 111 are connected with a connecting block 114. The two sides of the bottom of the inner bin 3 are fixedly connected by the connecting block 114. The transmission rod 112 is sleeved with a first bevel gear 113 on its exterior; a hinge shaft 121 is connected between the rotating parts of the two hinges 12, and a second bevel gear 122 is sleeved on the exterior of the hinge shaft 121. The first bevel gear 113 and the second bevel gear 122 are staggered and arranged with tooth surfaces facing each other. The telescopic rod 131 is sleeved with a driving bevel gear 132 on its exterior, and tooth grooves meshing with the surface teeth of the first bevel gear 113 and the second bevel gear 122 are respectively provided on both sides of the driving bevel gear 132. By default, the electromagnetic member 137 is not energized. Under the action of the spring 136, the telescopic rod 131 moves with the armature 135 in a direction away from the switching assembly 13. At this time, the driving bevel gear 132 is moved toward the first bevel gear 113 and meshes with it. By driving the telescopic rod 131 to rotate, the transmission rod 112 can be driven to rotate. The transmission rod 112 then drives the two sets of guide rods 111 to rotate through the gears, thereby pushing the connecting block 114 connected to its external thread to rise and fall inside the side rail 11, so that the inner bin 3 connected to the connecting block 114 can be lifted and retracted on the top of the box body 1 and the cover plate 2; Furthermore, when the electromagnetic part 137 is energized, it generates electromagnetic force to move the telescopic rod 131 at the end of the armature 135 in the direction of the switching component 13. During this process, while compressing the spring 136, the driving bevel gear 132 will be moved toward the second bevel gear 122 and mesh with it. By driving the telescopic rod 131 to rotate, the hinge shaft 121 can be driven to rotate, so that the cover plate 2 can be opened or closed from the front of the box body 1.

[0025] It is worth noting that in order to drive the telescopic rod 131 to rotate and prevent the telescopic rod 131 from affecting the switch motor 14 in driving the telescopic rod 131 to rotate during the telescopic process, a rib 133 is provided on the outer side of the end of the telescopic rod 131, and a pulley 134 is provided at the end of the telescopic rod 131 through the rib 133. The output shaft of the switch motor 14 is connected to the pulley 134 through a belt transmission. Under the action of the rib 133, the pulley 134 can move on the outer side of the end of the telescopic rod 131 through the rib 133, and at the same time, it does not affect the switch motor 14 driving the telescopic rod 131 to rotate through the pulley 134.

[0026] The bottom of the inner bin 3 is connected to the inner bin cover 31 via a rotating shaft, and a strap 32 is further connected between the inner bin 3 and the inner bin cover 31. When the inner bin 3 is raised out of the top outer side of the box body 1, the inner bin cover 31 will open outward due to gravity and be horizontally supported by the strap 32 and the support plate 21, which can assist the user to take items in the box body 1. At the same time, the inner bin cover 31 can also be used as a table top. When the inner bin 3 is put into the box body 1, the inner bin cover 31 will be squeezed by the support plate 21 and automatically closed upward.

[0027] The electric folding suitcase disclosed in the present invention can not only open the cover 2 by means of the switch motor 14, but also drive the switch motor 14 by means of the switching component 13 to raise the inner compartment 3 from between the case body 1 and the cover 2, so that people with mobility impairments or in public places can store and retrieve things while standing, without having to put the suitcase on the ground to search for them, which makes it more convenient to use.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
