[0046] Figures 1-10 It is shown that the structure diagram of the application, please refer to Figures 1-10 For the anti-skid multifunctional travel suitcase is introduced in detail.

[0047] Embodiment 1

[0048] Reference Figures 1-10 The application discloses an anti-skid multifunctional travel suitcase, which comprises a box body 100, a locking mechanism, an adsorption mechanism 300 and an unlocking mechanism 400.

[0049] Reference Figures 1-2 The box body 100 is used for carrying clothes and personal belongings of travelers, and comprises a box body 110 and a mobile base 120 located at the bottom of the box body 110.

[0050] In this embodiment, referring to Figures 1-6 The mobile base 120 comprises a bottom plate 120a located at the bottom of the box body 110 and a roller assembly 120b located at the bottom of the bottom plate 120a.

[0051] The roller assembly 120b comprises two driving wheels 120b-1 symmetrically installed at one end of the bottom of the bottom plate 120a and two guide wheels 120b-2 symmetrically installed at the other end of the bottom of the bottom plate 120a.

[0052] In this embodiment, referring to Figures 4-8The bottom of the bottom plate 120a is provided with a connecting seat 120a-1 with a connecting hole 120a-11 inside, which is used for facilitating connection with the connecting shaft 220a-1, and then facilitating rotation of the connecting block 220a, which is used for movably connecting the entire locking piece with the connecting seat 120a-1, and then facilitating switching of the locking mechanism 200 between the first state and the second state;

[0053] In the embodiment, reference is made to Figures 4-8 The bottom of the bottom plate 120a is provided with a connecting frame 120a-2 with an inner wall having a limiting sliding groove 120a-21, which is used for connecting with the connecting rod 310a and then connecting the suction cup 310. The limiting sliding groove 120a-21 is used in cooperation with the limiting sliding block 310a-1, wherein the limiting sliding groove 120a-21 is perpendicular to the ground, so as to make the suction cup 310 move along the limiting sliding groove 120a-21 in a straight line, and then make the suction cup 310 more firmly adsorbed after being perpendicular to the ground.

[0054] Reference is made to Figures 2-8 The locking mechanism 200 is used for automatically locking the moving base 120 when the moving base 120 stops moving. The locking mechanism 200 is installed on the moving base 120 and has a first state in which the locking mechanism 200 cannot lock the moving base 120 when the moving base 120 moves, and a second state in which the locking mechanism 200 automatically locks the moving base 120 after the moving base 120 is stationary. The locking mechanism 200 cannot lock the moving base 120 in the first state, and then facilitates continuous movement of the moving base 120. When the moving base 120 is stationary, the locking mechanism 200 automatically locks the moving base 120 in the second state, and then avoids sliding of the moving base 120.

[0055] In the embodiment, reference is made to Figures 2-8 The locking mechanism includes a locking wheel 210 installed at the bottom of the bottom plate 120a, a locking piece 220 installed at the bottom of the bottom plate 120a and locking the locking wheel 210, and a transmission member 230 connected with the driving wheel 120b-1 and the locking wheel 210 at both ends. The locking wheel 210 is used for locking the driving wheel 120b-1 in cooperation with the locking piece 220. The locking piece 220 is used for locking the locking wheel 210 after the locking wheel 210 stops rotating. The transmission member 230 is used for transmissionally connecting the driving wheel 120b-1 with the locking wheel 210, and then facilitating driving of the locking wheel 210 to stop rotating after the driving wheel 120b-1 stops rotating, and then automatically locking the locking wheel 210 by the locking piece 220.

[0056] In the embodiment, reference is made to Figures 2-8The locking wheel 210 includes a turntable 210a connected to the bottom of the base plate 120a and multiple drive blocks 210b evenly arranged in the circumferential direction of the turntable 210a with inclined bottoms. The turntable 210a is used to drive the drive wheel 120b-1 to rotate when the drive wheel 120b-1 rotates, thereby driving the multiple drive blocks 210b to rotate. When the drive blocks 210b rotate, they drive the locking blocks 220b to move downwards, thereby preventing the locking blocks 220b from being locked into the locking slots. Among them, the multiple drive blocks 210b form locking slots to prevent the locking blocks 220b from being locked into the locking slots after the turntable 210a stops rotating, thereby locking the turntable 210a and preventing the drive wheel 120b-1 from rotating.

[0057] In this embodiment, reference Figures 4-10 The locking mechanism includes a connecting block 220a located within the connecting seat 120a-1 and having connecting shafts 220a-1 on both sides, and a locking block 220b located on one side of the connecting block 220a and adapted to the locking slot. The connecting block 220a is used to facilitate connection with the connecting seat 120a-1. The connecting shafts 220a-1 are used to facilitate rotation of the locking block 220b after connection with the connecting hole 120a-11. The connecting shafts 220a-1 extend into the connecting hole 120a-11. A torsion spring 220a-11 is sleeved on the outside of the connecting shaft 220a-1, with one end connected to the side wall of the connecting shaft 220a-1 and the other end connected to the inner wall of the connecting hole 120a-11, for use in... The torsion spring 220a-11 continuously drives the connecting shaft 220a-1 to rotate, thereby causing the locking block 220b to rotate towards the side facing the slot. This facilitates the locking block 220b to rotate into the slot under the torsion of the torsion spring 220a-11 when the turntable 210a stops rotating, thus locking the turntable 210a. The top side wall of the locking block 220b has an arc-shaped structure, which is used to drive the locking block 220b to reciprocate downwards by cooperating with the inclined surface of the drive block 210b when the turntable 210a rotates and drives multiple drive blocks 210b to rotate. This is used to prevent the locking block 220b from being locked into the slot during the movement of the housing 100.

[0058] In this embodiment, reference Figures 4-7 The transmission component 230 includes a first helical gear set 230a connected at one end to the bottom of the turntable 210a and a first transmission rod 230b connected at the other end to the side wall of the drive wheel 120b-1. The first helical gear set 230a is used to drive the turntable 210a to rotate when it rotates, and the first transmission rod 230b is used to drive the turntable 210a to rotate when the drive wheel 120b-1 rotates and drives the first transmission rod 230b to rotate.

[0059] In this embodiment, reference Figures 1-9The locking member 220 further comprises a driving plate 220c provided on the side of the connecting block 220a away from the clamping block 220b and having a moving groove 220c-1 on the top surface, the driving plate 220c is used to drive the moving block 220c-11 to slide along the moving groove 220c-1 under the cooperation of the moving groove 220c-1 when the connecting block 220a rotates to drive the driving plate 220c to rotate, the moving block 220c-11 is slidably connected in the moving groove 220c-1 and has a hinged seat 220c-111 at the bottom, the moving block 220c-11 is used to drive the hinged seat 220c-111 to move when sliding along the moving groove 220c-1, the hinged seat 220c-111 is used to be hinged with the hinge 310a-2, so as to facilitate the movement of the connecting rod 310a and the suction cup 310 when the driving plate 220c rotates to drive the moving block 220c-11 to slide along the moving groove 220c-1.

[0060] With reference to Figures 2-9 The suction mechanism 300 is used to increase the suction force between the moving base 120 and the ground after the locking mechanism 200 locks the driving wheel 120b-1, so that the entire box body 100 is more stable, the suction mechanism 300 is installed at the bottom of the moving base 120, when the locking mechanism 200 is switched from the first state to the second state of locking the moving base 120, the suction mechanism 300 automatically suctions the moving base 120 to the ground, so that the moving base 120 is more firmly adsorbed to the ground, thereby avoiding the limited friction between the driving wheel 120b-1 and the guide wheel 120b-2 and the ground after the driving wheel 120b-1 is locked, causing the entire box body 110 to slip and be unstable.

[0061] In this embodiment, with reference to Figures 2-9 The suction mechanism 300 comprises a suction cup 310 having a connecting rod 310a at the top and an air extraction assembly 320 provided on the top of the suction cup 310, the suction cup 310 is used to automatically start to descend and contact the ground after the locking mechanism 200 tightly locks the driving wheel 120b-1, and then is adsorbed to the ground, the air extraction assembly 320 is used to extract the air in the suction cup 310 when the suction cup 310 descends, so that the inside of the suction cup 310 is in a vacuum state after contacting the ground, so that the suction cup 310 is more firmly adsorbed to the ground, the side wall of the connecting rod 310a has a limiting sliding block 310a-1 extending into the limiting sliding groove 120a-21, which is used to cooperate with the limiting sliding groove 120a-21 to keep the suction cup 310 always perpendicular to the bottom of the bottom plate 120a and the ground when moving up and down, so that the suction cup 310 is more firmly adsorbed to the ground after contacting the ground.

[0062] In this embodiment, with reference to Figures 8-9The top of the connecting rod 310a is provided with a hinge joint 310a-2 hinged with the hinge seat 220c-111, so as to be hinged with the hinge seat 220c-111, and when the driving plate 220c rotates, the moving block 220c-11 slides along the moving groove 220c-1, thereby facilitating the upward and downward movement of the suction cup 310.

[0063] With reference to Figures 4-9 The air suction assembly 320 includes an air guide cylinder 320a located at the top of the suction cup 310 and communicating with the inside of the suction cup 310, and an air suction member 320b located at the bottom of the bottom plate 120a. The air guide cylinder 320a is used to facilitate the air suction member 320b to suck out the air in the suction cup 310 through the air guide cylinder 320a when the suction cup 310 is lowered.

[0064] With reference to Figures 4-9 The air suction member 320b includes a fixed rod 320b-1 located at the bottom of the bottom plate 120a and a fixed plug 320b-2 located at the bottom of the fixed rod 320b-1 and inside the air guide cylinder 320a. The fixed rod 320b-1 is used to fix the fixed plug 320b-2, and the fixed plug 320b-2 is used to move as a piston in the air guide cylinder 320a when the suction cup 310 moves up and down. When the suction cup 310 is lowered and contacts the ground, the fixed plug 320b-2 moves upward relative to the suction cup 310, thereby sucking out the air in the suction cup 310 through the air guide cylinder 320a, so that the suction cup 310 is more firmly adsorbed to the ground. The outer wall of the fixed plug 320b-2 is tightly fitted with the inner wall of the air guide cylinder 320a, so as to avoid the internal communication with the external air when the suction cup 310 contacts the ground, thereby preventing the fixed plug 320b-2 from moving upward relative to the air guide cylinder 320a when the air in the suction cup 310 is sucked out.

[0065] With reference to Figures 1-10 The unlocking mechanism 400 is used to unlock the locking mechanism when the traveler needs to continue to push the box body 100, thereby facilitating the continued pushing of the entire box body 100 to move. The unlocking mechanism 400 is installed below the moving base 120 and is in transmission connection with the locking mechanism 200. When the unlocking mechanism 400 works, the locking mechanism 200 is switched from the second state to the first state, thereby preventing the locking mechanism from locking the moving base 120, and facilitating the traveler to continue to push the box body 100 to move.

[0066] In the embodiment, the unlocking mechanism 400 comprises a second transmission rod 410 with one end penetrating through the side wall of the connecting seat 120a-1 and connecting with the side wall of the connecting shaft 220a-1, a second bevel gear set 420 with one end connected with the other end of the second transmission rod 410 and away from the connecting shaft 220a-1, and a third transmission rod 430 with one end connected with the other end of the second bevel gear set 420 and the other end provided with a pedal 430a, the second transmission rod 410 is used to rotate the connecting shaft 220a-1, the second bevel gear set 420 is used to drive the third transmission rod 430 to rotate when the second transmission rod 410 rotates, and the third transmission rod 430 is used to rotate the second bevel gear set 420 when the third transmission rod 430 rotates by stepping on the pedal 430a, the second bevel gear set 420 rotates to drive the second transmission rod 410 to rotate, the second transmission rod 410 rotates to drive the connecting shaft 220a-1 to rotate, the connecting shaft 220a-1 rotates to drive the clamping block 220b to rotate, and then the clamping block 220b rotates out of the clamping groove, at this time, the box body 100 is continuously moved, and after the pedal 430a is released, the clamping block 220b is pressed by the driving block 210b, so that the locking mechanism 200 cannot lock the driving wheel 120b-1, thereby facilitating the continuous movement of the box body 100.

[0067] In the embodiment, the specific use process is as follows: when the traveler uses the box body 100, the box body 100 stops moving, at this time, the clamping block 220b automatically rotates into the clamping groove under the torsion of the torsion spring 220a-11, thereby automatically locking the driving wheel 120b-1, at this time, the box body 100 cannot be moved, thereby avoiding the free movement of the box body 100, at the same time, the locking mechanism 200 automatically drives the suction cup 310 to contact the ground when locking the driving wheel 120b-1, and the air in the suction cup 310 is sucked out by the air suction assembly 320, so that the suction cup 310 is adsorbed on the ground, thereby increasing the friction between the entire moving base 120 and the ground, so that the box body 100 is more stable, when the box body 100 needs to be moved continuously, the pedal 430a is stepped on, thereby driving the third transmission rod 430, the second bevel gear set 420 and the second transmission rod 410 to rotate, thereby indirectly driving the clamping block 220b to rotate reversely, so that the clamping block 220b is away from the clamping groove, at this time, the user timely pushes the box body 100 to drive the driving wheel 120b-1 to rotate, thereby driving the plurality of driving blocks 210b to press the clamping block 220b when the rotating disc 210a rotates, so that the clamping block 220b cannot enter the clamping groove, thereby releasing the locking state of the locking mechanism to the driving wheel 120b-1.
