[0002] As an indispensable equipment in modern travel, the design of electric luggage constantly pursues the perfect combination of portability and practicality. However, there are certain limitations in the handle design of existing electric luggage. Most electric luggage adopts a non-foldable handle design, and this design usually requires opening a notch on the luggage body that matches the handle to achieve storage. Although this design is simple, in luggage of the same size, it will inevitably reduce the storage space inside the luggage, thus affecting the practicality of the luggage.

[0003] To solve the problem of the space occupied by non-foldable handles, some electric luggage adopts a foldable handle design. As shown in the patent of CN211559036U, this design allows the handle to be folded and stored when not needed to save space. However, the design of such folding handles is often relatively complex, which not only increases the production cost but also has a poor adaptability to the luggage in actual use, resulting in low use convenience.

[0004] Therefore, in order to further simplify the folding mechanism of the handle structure of existing electric luggage and further improve its applicability. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-5 For an embodiment of the present invention, it discloses an electric trolley case with a retractable handle structure. The electric trolley case includes a box body 1 and a wheel assembly 2. Specifically, the wheel assembly 2 includes a telescopic rod 21 connected to a driving member inside the box body 1. The telescopic rod 21 is fixed by a hoop to achieve extension or contraction. The telescopic rod 21 is driven by an internal driving member to move back and forth, so as to push the entire wheel assembly 2 outwards or retract it. A wheel set 22 is installed below the telescopic rod 21;

[0024] Among them, a cross bar 23 is fixedly installed at the top of the telescopic rod 21. Handle parts 24 are rotatably connected to both sides of the cross bar 23. The handle parts 24 and the cross bar 23 are buckled by a lock assembly; A twist grip assembly 3 is also installed on the handle part 24. Specifically, in this embodiment, the twist grip assembly 3 includes a brake twist grip and a speed control twist grip. Its specific structure and principle have been disclosed in the prior art and will not be elaborated here. A baffle 4 is fixedly installed on the front side of the telescopic rod 21.

[0025] In some embodiments, the handle part 24 in the present invention includes a rod 241 and a ferrule 242 fixedly connected to the end of the rod 241. Seats 25 are fixedly installed at both ends of the cross bar 23. The ferrule 242 is rotatably connected to the seat 25. That is to say, in the present invention, the ferrule 242 and the seat 25 are pinned and rotated to realize the folding and rotation of the entire handle part 24. It should be further noted that in this embodiment, the handle part 24 folds and retracts in the direction of the bottom of the telescopic rod 21.

[0026] Based on the above embodiments, in this embodiment, the latch assembly includes a positioning glass bead 26 embedded inside the card seat 25. A hole adapted to the telescopic end of the positioning glass bead 26 is provided on the outer side of the card sleeve 242. The card sleeve 242 rotates and is snap-connected to the outer side of the card seat 25. That is, in the unfolded state, the card sleeve 242 rotates and is sleeved on the outer side of the card seat 25. The telescopic end of the positioning glass bead 26 on the card seat 25 is snap-connected into the hole of the card sleeve 242 to complete the locking and fixing of the position of the card sleeve 242. When the handle member 24 needs to be folded and stored, the telescopic end of the positioning glass bead 26 can be pressed to retract it to one side of the hole. At this time, the handle member 24 can be freely rotated downward for folding.

[0027] In some embodiments, a positioning assembly 5 adapted to the handle member 24 is further provided inside the baffle 4. Among them, the positioning assembly 5 includes two connecting seats 51. A lock ring 52 is fixedly connected between the two connecting seats 51. After the handle member 24 is folded, it is inserted into the inside of the lock ring 52. Among them, a connecting rod 53 connected to the baffle 4 is fixedly provided at the end of one of the connecting seats 51.

[0028] In the present utility model, through the design of the lock ring 52, on the one hand, it can be used to hang items. In addition, when the handle member 24 is folded downward and the telescopic rod 21 contracts, the rod 241 of the handle member 24 can be inserted into the inside of the lock ring 52. In this way, the positioning of the position of the handle member 24 in the storage state can be improved, and the stability of storage is enhanced.

[0029] In a preferred embodiment, a hole is provided at the end of the other connecting seat 51 in the present utility model. A ejector rod 55 is movably inserted into the hole through a spring 54. The hole penetrates the connecting seat 51. One end of the ejector rod 55 can be inserted into the inside of the lock ring 52.

[0030] Specifically, a groove 11 for accommodating the telescopic rod 21 is provided on the side of the box body 1 in this embodiment. The baffle 4 covers the front side of the groove 11. The ejector rod 55 abuts against the end face of the groove 11. That is to say, in this embodiment, the movably inserted ejector rod 55 is used to abut against the inside of the groove 11. When in the storage state, the ejector rod 55 is abutted by the inner wall of the groove 11 and is reversely inserted into the inside of the lock ring 52. In this way, the rod 241 in the lock ring 52 is abutted and limited, so as to further improve the storage stability of the handle member 24. Of course, a rubber block can be fixedly installed at the end of the ejector rod 55. The rubber block is used to achieve flexible contact with the rod 241 and provide a certain deformation space, so as to ensure the stability of the abutment of the ejector rod 55 against the rod 241.

[0031] In summary, in the present utility model, by adopting two handle members 24 that rotate downward, the storage space of the handle part is effectively saved. Secondly, the handle member 24 can be stored together with the telescopic rod 21 inside the groove 11 of the luggage, without occupying too much space inside the luggage, and the folding storage is convenient. In addition, through the positioning assembly 5 inside the baffle 4 provided in the present utility model, the handle member 24 can be loop-positioned when the handle member 24 is stored. In this way, the stability of the storage of the handle member 24 can be improved in the storage state. The overall structure design is simple, and the convenience of assembly and operation is improved.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
