Description

Technical Field

[0001] This application relates to the field of electric luggage technology, and in particular to an electric luggage with a folding and collapsible frame. Background Technology

[0002] With the increasing demand for portable travel, electric suitcases, as innovative products that combine transportation and storage, are gradually becoming a popular choice for business trips and short-distance travel. Electric suitcases integrate a drive system (including a motor, battery, and control system), wheels, and braking devices into the traditional suitcase, enabling autonomous movement and effortless pushing, significantly reducing the burden on users carrying heavy items.

[0003] However, due to the requirements of integrated product design, the internal space allocation of electric suitcases faces strict constraints: core components such as the drive system and battery pack need to occupy key areas such as the bottom and back of the suitcase, resulting in a 15%-30% reduction in actual storage space compared to traditional suitcases of the same size. Furthermore, the internal space also contains protruding battery compartments, motor wiring channels, and other structures, further compressing the effective storage volume. Currently, all electric suitcases on the market suffer from these problems. For example, an electric suitcase disclosed in Chinese patent document CN201320266446.X includes a handle and a suitcase body. A slide rail is provided on the back of the suitcase body, and a pull rod is installed within the slide rail. The handle is inserted into the pull rod. The bottom of the suitcase body has a cavity separated by a partition. A lithium battery, a DC motor, a DC PWM motor speed control device, a DC generator, a rotating rod, and two sets of gears are fixed at the bottom of the cavity. Each of the two sides of the suitcase exterior has a caster wheel. Travelers can start and control the electric movement of the suitcase using a switch and speed control device on the handle.

[0004] The internal design of the aforementioned electric suitcases still follows the traditional suitcase's "unsupported storage mode," relying solely on dividers and elastic straps for simple partitioning. It has not been specifically optimized for the characteristics of small space and irregular shape, resulting in a significant reduction in storage efficiency and ease of use.

[0005] Therefore, providing an electric suitcase with a folding and collapsible frame, which can achieve orderly storage and stable fixation of items in a limited and irregular space through a support structure, has become a key technical direction for improving the competitiveness of electric suitcase products, and is something that those skilled in the art need to do.

The two sides of the bottom partition cover 13 together with the openable and closable outer cover 11 and the fixed outer cover 15 on the electric suitcase body 10 to form a bottom interlayer cavity 14. That is, there are two bottom interlayer cavities 14, which are located on both sides of the bottom partition cover 13 respectively, and the bottom interlayer cavity 14 is connected to the storage cavity 12.

[0028] Understandably, the electric luggage box described in this application also includes components such as a steering handle, a telescopic motor, and a battery. For details on the specific structure, please refer to the novel electric luggage box disclosed in Chinese Invention Patent CN202211162539.8, which will not be elaborated here.

[0029] Further, please refer to Figure 2 , Figure 4 , Figure 5 The electric luggage compartment 10 is equipped with a first folding / retracting frame 20 and a second folding / retracting frame 30. The first folding / retracting frame 20 is located in the bottom interlayer cavity 14 near the fixed outer cover 15, and the second folding / retracting frame 30 is located in the bottom interlayer cavity 14 near the openable / closed outer cover 11. The first folding / retracting frame 20 has a retracted state and an extended state. In the extended state, a portion of the first folding / retracting frame 20 slides from the bottom interlayer cavity 14 into the storage cavity 12 and is fixedly connected to the inner wall of the storage cavity 12. In the retracted state, the first folding / retracting frame 20 retracts into the bottom interlayer cavity 14 to reduce the occupation of the storage cavity 12, fully utilize the internal cavity of the electric luggage compartment 10, and improve space utilization.

[0030] The second folding and retractable frame 30 is slidably disposed within the bottom interlayer cavity 14 near the opening and closing outer cover 11, and the second folding and retractable frame 30 can slide from the bottom interlayer cavity 14 into the storage cavity 12. In use, the second folding and retractable frame 30 is pulled out from the bottom interlayer cavity 14 and slid into a fixed position within the storage cavity 12. After use, the second folding and retractable frame 30 is slid back into the bottom interlayer cavity 14, further ensuring the utilization rate of the internal cavity of the electric luggage case 10.

[0031] Specifically, please refer to Figures 2-7 The first folding and retractable frame 20 includes a telescopic base 21 fixedly connected to the bottom interlayer cavity 14. A first telescopic rod 22 is slidably disposed within the telescopic base 21, a second telescopic rod 23 is slidably disposed within the first telescopic rod 22, and a third telescopic rod 24 is slidably disposed within the second telescopic rod 23. The first telescopic rod 22, the second telescopic rod 23, and the third telescopic rod 24 can all retract into the bottom interlayer cavity 14. Simultaneously, snap-fit ​​components 25 are respectively provided between the first telescopic rod 22 and the telescopic base 21, between the second telescopic rod 23 and the first telescopic rod 22, and between the third telescopic rod 24 and the second telescopic rod 23. The snap-fit ​​components 25 include, but are not limited to, ball-head plungers. A connector 26 is provided on the top of the storage cavity 12 of the electric luggage compartment 10, and the third telescopic rod 24 is detachably connected to the connector 26. The connector 26 includes, but is not limited to, threaded pipe fittings.

[0032] In use, the first telescopic rod 22, the second telescopic rod 23, and the third telescopic rod 24 are pulled out sequentially from the telescopic base 21, so that the top of the third telescopic rod 24 is engaged with the connector 26. At this time, the positioning bead in the locking member 25 pops out and engages, achieving a limit and ensuring the stability of the first folding and shrinking frame 20 connection. When shrinking, the connector 26 is released, and the third telescopic rod 24, the second telescopic rod 23, and the first telescopic rod 22 are pressed down sequentially. At this time, the positioning pin in the locking member 25 is squeezed and shrinks, and the first telescopic rod 22, the second telescopic rod 23, and the third telescopic rod 24 shrink sequentially into the bottom interlayer cavity 14, completing the use and shrinking of the first folding and shrinking frame 20.

[0033] Please see Figures 4-7 The electric luggage box body 10 is provided with multiple sliding tracks 29 in the storage cavity 12. A pair of sliding tracks 29 are arranged opposite to each other on the side wall of the storage cavity 12 and close to the opening and closing outer cover 11, and a pair of sliding tracks 29 are arranged opposite to each other on the side wall of the storage cavity 12 and close to the fixed outer cover 15.

[0034] The first telescopic rod 22, the second telescopic rod 23, and the third telescopic rod 24 are symmetrically provided with partition brackets 27. The partition brackets 27 are horizontally arranged, and the ends of the partition brackets 27 are slidably disposed within the sliding rail 29. The partition brackets 27 are provided with a first mounting part 28.

[0035] Please see Figure 2 , Figure 6 The second folding and retractable frame 30 is a strip-shaped structure and is horizontally arranged in the sliding track 29 near the opening and closing outer cover 11. Multiple second folding and retractable frames 30 are provided, with one second folding and retractable frame 30 corresponding to a pair of partition brackets 27. A second mounting part 31 is provided on the second folding and retractable frame 30, and the first mounting part 28 and the second mounting part 31 are arranged opposite to each other. A partition 32 is detachably provided between the first folding and retractable frame 20 and the second folding and retractable frame 30, which can separate the storage cavity 12. Connecting parts 33 are provided on opposite sides of the partition 32; one connecting part 33 is installed in the first mounting part 28, and the other connecting part 33 is installed in the second mounting part 31.

[0036] The sliding track 29 is provided with a threaded locking member 34. The threaded end of the threaded locking member 34 extends into the sliding track 29 and can be threadedly connected to the second folding and shrinking frame 30 to fix the second folding and shrinking frame 30 to the sliding track 29 and ensure stability during use.

[0037] In this embodiment, a groove (not shown in the figure) is provided on the sliding track 29. The ends of the dividing bracket 27 and the second folding and shrinking frame 30 extend into the groove. Rollers (not shown in the figure) are provided on the ends of the dividing bracket 27 and the second folding and shrinking frame 30 located in the groove to ensure the stability of sliding. The rollers are rubber wheels to reduce gaps and further improve the stability of use.

[0038] In this embodiment, the sliding track 29 is inclined at an angle of 1.5° to 2.5°. The separator 32 is made of an elastic material, such as polyester, to ensure ease of installation. Because the sliding track 29 is inclined, the distance between the sliding track 29 near the opening / closing cover 11 and the sliding track 29 near the fixed cover 15 is narrower at the top and wider at the bottom. Thus, when a second folding / shrinking frame 30 corresponds to a separator bracket 27, moving the second folding / shrinking frame 30 upwards shortens the distance between the corresponding separator bracket 27 and the corresponding second folding / shrinking frame 30, facilitating the installation of the separator 32 between the separator bracket 27 and the second folding / shrinking frame 30. After the separator 32 is installed, moving the second folding / shrinking frame 30 downwards gradually increases the distance between the separator bracket 27 and the second folding / shrinking frame 30, while simultaneously tensioning the separator 32. This achieves rapid installation and ensures that the separator 32 is taut within the storage cavity 12, guaranteeing stability during use.

[0039] In use, first unfold and fix the first folding retractable frame 20. Move one second folding retractable frame 30 to correspond to one partition bracket 27. Move the second folding retractable frame 30 upward a short distance to install the partition 32 between the partition bracket 27 and the second folding retractable frame 30. Move the second folding retractable frame 30 downward a short distance to tension the partition 32. Rotate the threaded locking member 34 to fix the second folding retractable frame 30 to the sliding rail 29, completing the installation. In disassembly, first rotate the threaded locking member 34, then move the second folding retractable frame 30 upward a short distance to loosen the partition 32. Remove the partition 32 and retract the second folding retractable frame 30 into the bottom interlayer cavity 14, completing the use and retraction of the second folding retractable frame 30.

[0040] In this embodiment, the connecting part 33 on the separator 32 is a dovetail tenon, and the first mounting part 28 and the second mounting part 31 are dovetail grooves. The dovetail tenon is snapped into the dovetail groove to achieve quick assembly and disassembly.

[0041] In other embodiments, the connecting portion 33 on the separator 32 is a snap fastener, and the first mounting portion 28 and the second mounting portion 31 are slots. The snap fastener is engaged in the slots to ensure connection stability.

[0042] In other embodiments, one side connecting portion 33 of the partition 32 is fixedly connected to the first mounting portion 28, and the other side connecting portion 33 of the partition 32 is detachably connected to the second mounting portion 31. Thus, after the second folding and shrinking frame 30 is removed, the partition 32 retracts into the bottom interlayer cavity 14 along with the first folding and shrinking frame 20, further improving space utilization, reducing the number of accessories, reducing installation steps, and improving ease of use.

[0043] This application achieves spatial division of the internal storage cavity 12 of the electric luggage compartment 10 by setting a slidable first folding and retractable frame 20 and a second folding and retractable frame 30, and setting a separator 32 between the first folding and retractable frame 20 and the second folding and retractable frame 30, which facilitates users to classify and store items and improves the usability. At the same time, the first folding and retractable frame 20, the second folding and retractable frame 30, and the separator 32 can all be retracted into the bottom interlayer cavity 14 on the electric luggage compartment 10, thereby reducing the amount of storage space occupied in the internal storage cavity 12 and improving space utilization.

[0044] It is understood that this application has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, based on the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application.
