DETAILED DESCRIPTION

[0035] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0036] As Figures 1-13As shown, a telescopic electric suitcase includes a box assembly 1, a handle assembly 2, a base assembly 3, and a front wheel assembly 4 and a rear wheel assembly 5 at the bottom, a steering assembly 8 is arranged between the front wheel assembly 4 and the handle assembly 5, the box assembly 1 is detachably mounted on the base assembly 3, and the user can sit on the box assembly 1 and drive the electric suitcase forward by holding the handle assembly 2. The base assembly 3 includes a telescopic outer rod assembly 6 and a telescopic inner rod assembly 7, one end of the telescopic inner rod assembly 7 is movably connected to the inside of the telescopic outer rod assembly 6, and the other end is connected to the steering assembly 8. The user can extend or retract the base assembly 3 according to his own use requirements to meet different use requirements in different scenes and also meet the comfortable driving experience of people of different heights.

[0037] It also includes a shell 9 that wraps the handle assembly 2 and the steering assembly 8, and the shell 9 is formed by mutually buckling two front and rear shells to protect the internal structure. The base assembly 3 is provided with a locking mechanism 10 inside or outside, which locks the telescopic inner rod assembly 7 and the telescopic outer rod assembly 6 through the locking mechanism 10 to prevent the telescopic outer rod assembly 7 or the telescopic inner rod assembly 6 from being retracted due to bumps during driving, increase the stability of the product, and also ensure a good user experience. It also includes a pulling mechanism 11 connected to the locking mechanism 10, which drives the locking mechanism 10 to move for unlocking by pulling the pulling mechanism 11. After unlocking, it can be manually retracted. The unlocking method is simple and convenient to use.

[0038] The locking mechanism 10 is fixed inside the telescopic inner rod assembly 7 by screws, and the locking mechanism 10 includes a base 16, a movable drive rod 17 mounted in the base 16, and a lock block 18. The drive rod 17 is connected to the lock block 18, and the pulling mechanism 11 is connected to the drive rod 17. The pulling mechanism 11 drives the drive rod 17 to move, and the drive rod 17 drives the lock block 18 to move to achieve unlocking.

[0039] The lock block 18 is provided with a bolt 19 that passes through the telescopic inner rod assembly 7, and the telescopic outer rod assembly 6 is provided with a plurality of bolt holes 20 through which the bolt 19 passes. The plurality of bolt holes 20 are in the same horizontal direction, and the bolt 19 is inserted into different positions of the bolt holes 20 to achieve fixation after retraction.

[0040] The base 16 is provided with a first groove 21 and a second groove 22 in communication, the drive rod 17 is movably mounted in the first groove 21, and the lock block 18 is movably mounted in the second groove 22. A reset spring 23 is arranged between the second groove 22 and the bottom of the lock block 18. After the lock block 18 moves, the reset spring 23 resets the lock block 18, and the drive rod 17 is also reset.

[0041] The bottom of the driving rod 17 is provided with a first inclined block 24, and the top of the locking block 18 is provided with a second inclined block 25 which is fitted to the first inclined block 24. The two reverse inclined surfaces are fitted to each other. When the driving rod 17 moves horizontally, the first inclined block 24 moves horizontally synchronously, and the inclined surface on the second inclined block 25 gradually moves downward along the inclined surface on the first inclined block 24. The locking block 18 drives the bolt 19 to move downward to be separated from the bolt hole 20. At this time, the locking state is released, and the telescopic inner rod assembly 7 can be manually pulled out or pushed in. The locking mechanism 10 moves synchronously with the telescopic inner rod assembly 7. When the bolt 19 is displaced to be directly below another bolt hole 20, the locking block 18 is subjected to the elastic force of the return spring 23, and the bolt 19 is again inserted into the bolt hole 20 to form a lock.

[0042] The pulling mechanism 11 includes a handle 12 and a linkage member 44 which moves with the handle 12. The handle 12 is manually pivoted to drive the driving rod 17 to move for unlocking through the linkage member 44. The linkage member 44 includes a rotating block 13, a traction wire 14 and a column 15 which is protruded on the inner side of the handle 12. The rotating block 13 is pivoted by a rotating shaft through the center thereof and is limited by a screw. The rotating block 13 can rotate left and right with the center as the pivot point. The traction wire 14 is connected to one end of the rotating block 13, and the column 15 is in contact with the other end of the rotating block 13. The handle 12 drives the rotating block 13 to rotate through the column 15, and simultaneously drives the traction wire 14 to move. The driving rod 17 is driven to move by the traction wire 14 to separate the bolt 19 from the bolt hole 20, so as to release the locking state of the locking mechanism 10.

[0043] The working principle of the pulling mechanism 11 is as follows: the column 15 is perpendicular to the rotating block 13. When the handle 12 is pivoted, the column 15 rotates forward and backward with the handle 12, and the rotating block 13 rotates left and right. When the user pulls the handle 12, the column 15 presses down one side of the rotating block 13, and the other side of the rotating block 13 which is connected to the traction wire 14 rises to realize pulling the traction wire 14.

The telescopic inner rod assembly 7 is sleeved into the rear of the swivel joint 32 and is fixed by screws. When steering, the user holds the handlebar assembly 2 and rotates it to drive the front wheel assembly 4 to steer. Through the design of the bearings at the upper and lower ends of the swivel joint 32, the bearings 33 rotate when steering, and the swivel joint 32 does not rotate, so the telescopic inner rod assembly 7 does not deviate when steering.

[0047] The handlebar assembly 2 comprises a handlebar rod 34, a vertical rod 35, a connecting head 36, and an adjustable positioner 37. The vertical rod 35 is threadedly connected to the upper end of the wheel fork 30 and is reinforced by the connecting head 36 installed at the threaded connection to enhance the connection strength of the vertical rod 35 and the wheel fork 30 and prevent falling off and collapse.
