The upper box body shaft 4c is coaxially and fixedly sleeved with a second meshing type belt wheel 9f and a second gear 9e, and the second meshing type belt wheel 9f and the second gear 9e are positioned right above the first meshing type belt wheel 9b and the first gear 9d and are arranged in parallel up and down. The upper part of the vertically-arranged meshing type conveyor belt 9a is meshed with a second meshing type belt wheel 9f, and the lower part is meshed with a first meshing type belt wheel 9b.
When the first transmission mechanism 9 works, the motor 9g drives the motor gear 9c to transmit power to the first gear 9d, and the first gear 9d is fixed on the front box body shaft 4a, so that the front main panel 4 is driven by the front box body shaft 4a to rotate forwards, and meanwhile, the front box body shaft 4a drives the first meshing type belt wheel 9b to rotate forwards around the front box body shaft 4a. The first meshing type pulley 9b transmits power to the second meshing type pulley 9f above through the meshing type conveyor belt 9a, and the second meshing type pulley 9f transmits power to the second gear 9e through the upper box body shaft 4c.
Similarly, the structure of the second transmission mechanism 9 connected to the rear main panel 7 is the same as that of the first transmission mechanism 9, and when the second transmission mechanism 9 works, the rear main panel 7 is driven to rotate backwards, and finally the power is transmitted to the second gear 9e belonging to the second transmission mechanism 9.
Referring to fig. 6 and 3, the rear upper top plate 6 is described as an example: a rack 13 horizontally arranged front and back is fixedly connected to the lower bottom surface of the left end of the rear upper top plate 6, and the rack 13 is engaged with a second gear 9e above the second transmission mechanism 9, as shown in fig. 2 and 5. Thus, when the second gear 9e rotates, the rack 13 is moved, and the rear upper deck 6 is caused to slide rearward along the slide table 4g. In the same structure, the lower bottom surface of the right end of the front upper top plate 5 is fixedly connected with another rack 13 horizontally arranged back and forth, the rack 13 is meshed with a second gear 9e above the first transmission mechanism 9, and when the first transmission mechanism 9 works, the rack 13 drives the front upper top plate 5 to slide forwards along the sliding table 4g.
Hanging hooks 7b are provided on the upper and lower sides of the left and right side walls of the front main panel 4 and the rear main panel 7, respectively, and a hanging curtain 17 (see fig. 8) can be fixed.
Referring to fig. 5, a vertical transmission mechanism groove 7a is formed at the rear left corner of the rear main panel 7 for accommodating a meshing type conveyor belt 9a and the like in the second transmission mechanism 9; similarly, a vertical transmission mechanism groove 4f (see fig. 7) is also formed at the right front corner of the front main panel 4 for receiving the engaging belt 9a of the first transmission mechanism 9 to prevent human body and objects from colliding and interfering with the transmission mechanism 9.
Referring to fig. 7 and 4, a vertical lying plate 8 is arranged right behind the front main panel 4, the lying plate 8 is a rectangular flat plate, a cylindrical boss 8a is fixedly arranged at each of the left end and the right end of the bottom of the lying plate, a through hole is formed in the middle of the cylindrical boss 8a, the cylindrical boss 8a is sleeved on the front box body shaft 4a in a hollow mode with a gap through the through hole and is movably connected with the front box body shaft 4a in a clearance fit mode through a shaft hole, referring to fig. 4, the lying plate 8 can rotate relatively along the front box body shaft 4a, when the lying plate 8 is turned backwards around the front box body shaft 4a and then placed flatly, the lying plate 8 can be placed on the lower bottom plate 10 of the rear box body at the rear side of the luggage case, and spaces in front, rear and lower can be formed.
Referring to fig. 7, a buckle 16 is provided at the rear side of the lying plate 8, the buckle 16 is fixed on the left and right side walls of the front main panel 4, when the lying plate 8 is not needed, the lying plate 8 is vertically placed, and the buckle 16 is turned over to the lying plate 8 to block the lying plate 8, so that the lying plate 8 is fixed in a vertical state. When the space of the luggage case needs to be enlarged or the luggage case needs to be laid down for rest, the buckle 16 is only required to be manually released, and then the lying plate 8 is turned backwards around the front case body shaft 4a to be turned onto the rear lower plate 10.
Referring to fig. 1-7, when the suitcase disclosed by the invention is used as a traditional suitcase, a closed space formed by an upper top plate 5, a rear upper top plate 6, a front main panel 4, a rear main panel 7, a front lower bottom plate 2 and a rear lower bottom plate 10 is used as a storage part of the suitcase, the suitcase wheels 1 are in a movable state, the suitcase can be dragged to move by pulling the pull rod 3, the front-rear length of the electric push rod 12 is shortened to the shortest position, and the coded lock 4b is in a locked state, so that the stability and the safety of the suitcase are improved.
When the space in the luggage case needs to be enlarged due to the increase of objects in the traveling process, the coded lock 4b is unlocked, the external switch 14 is pressed, the electric push rod 12 is controlled to work and extend, the front side and the rear side of the luggage case are separated, as shown in fig. 8, and then the buckle 16 is manually released, and the lying plate 8 is placed on the rear lower plate 10 in a backward overturning manner. The prepared curtain cloth 17 is hung on the hanging buckles 7b at the left and right sides of the front main panel 4 and the rear main panel 7, and large articles in the box are prevented from falling.
When it is desired to rest on the luggage, in a state where the luggage space has been enlarged in fig. 8, the two transmission mechanisms 9 are simultaneously actuated, so that the front main panel 4 is rotated forward about the axis of the front luggage body shaft 4a and the rear main panel 7 is rotated backward about the axis of the rear luggage body shaft 4e, simultaneously, the front upper top plate 5 is caused to slide forward and the rear upper top plate 6 is caused to slide backward, as shown in fig. 9. When the rear upper top plate 6 slides backwards to the position of the spring pin positioning hole 4d at the rear, the spring pin arranged at the spring pin positioning hole 4d is fixed on the rear upper top plate 6 by the spring force, the front upper top plate 5 slides forwards to the position of the spring pin positioning hole 4d at the front, at the moment, the front main panel 4 turns forwards to the horizontal position, the rear main panel 7 also turns backwards to the horizontal position, the luggage case is finally unfolded to be used as a bed, at the moment, the front upper top plate 5, the rear upper top plate 6 and the luggage case wheel 1 are supported on the ground together, and then the locking device carried by the luggage case wheel 1 is pressed down to prevent the luggage case from rolling, so that the structural stability of the luggage case when being used as a bed is improved.
