[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-3 As shown, a bag base with elastic roller support includes a base plate 1 for the bottom of the bag. The base plate 1 is equipped with an auxiliary wheel module 14 and a drive wheel module 11. The drive wheel module 11 includes a support cylinder 12 connected to the base plate 1. The support cylinder 12 is arranged laterally, and a rotatable drive wheel body 13 is sleeved on the support cylinder 12. The auxiliary wheel module 14 provides rolling support to the base plate 1, enabling the bag to move; the drive wheel module 11 actively moves, driving the bag to move, thus having good practicality.

[0032] The auxiliary wheel module 14 includes a wheel bracket 2 mounted on the bottom of the base plate 1. The wheel bracket 2 is provided with a driven wheel 21 that can rotate passively. The wheel bracket 2 is provided with a longitudinally arranged elastic groove 24, and an elastically lifting mounting block 22 is installed in the elastic groove 24. The driven wheel 21 is mounted on the mounting block 22. Initially, the mounting block 22 elastically supports the base plate 1 under the action of elasticity. At this time, the drive wheel module 11 mounted on the base plate 1 will not touch the ground. When the bag is carrying a person, the compression spring 28 will be compressed. At this time, the wheel of the drive wheel module 11 can contact the ground. Only then can the drive wheel module 11 drive the base plate 1 to move when it moves. It has a foolproof function to prevent collision accidents when children ride in it.

[0033] The auxiliary wheel module 14 also includes a pair of left support wheels 15 and a pair of right support wheels 16; the left support wheels 15 and right support wheels 16 each include the wheel bracket 2. The wheel bracket 2 is equipped with a laterally arranged driven wheel axle 23, on which the driven wheel body 21 is sleeved, and the inner end of the driven wheel axle 23 is mounted on the mounting block 22. The driven wheel body 21 is rotatably sleeved in the driven wheel axle 23, achieving rolling support, and can rotate around the driven wheel axle 23 to achieve rolling cooperation with the ground, providing rolling support for the bag / suite.

[0034] The use of multi-point rolling support with one left support wheel 15 and one pair of right support wheels 16 further improves the stability of the support.

[0035] The top of the elastic groove 24 is provided with a top sealing block 25 to prevent the mounting block 22 from popping outward; when the suitcase carries an adult or a person whose weight exceeds the elastic support, the mounting block 22 located in the elastic groove 24 will pop up along the elastic groove 24. The sealing block can prevent the mounting block 22 located in the elastic groove 24 from popping out of the groove, ensuring the stability of the installation.

[0036] Furthermore, a first connecting post 26 is formed on the top of the mounting block 22, and a second connecting post 27 is formed on the bottom of the top sealing block 25. A compression spring 28 connects the first connecting post 26 and the second connecting post 27. In this embodiment, the compression spring 28 can elastically support the base plate 1, at which time the drive wheel module 11 mounted on the base plate 1 will not touch the ground; when the suitcase has a person carrying it, the compression spring 28 will be compressed, and only then can the wheel of the drive wheel module 11 contact the ground. Only then can the drive wheel module 11 drive the base plate 1 to move when it moves. This has a foolproof function, specifically, it can prevent lighter children from sitting in the suitcase and accidentally causing the suitcase to move forward, thus improving safety. Only after a person of a certain age and weight exceeding the prescribed limit sits on the suitcase can the compression spring 28 be compressed, allowing the bottom of the drive wheel module to contact the ground and realize the automatic movement of the suitcase.

[0037] Furthermore, the bottom of the mounting block 22 is a circular block, and the shape of the bottom of the elastic groove 24 is adapted to the bottom shape of the mounting block 22. When the base plate 1 is not carrying a person, the circular block at the bottom of the mounting block 22 will contact the bottom of the elastic groove 24 under the action of elasticity. Moreover, the width of the mounting block 22 is adapted to the width of the elastic groove 24, which can ensure the installation stability of the mounting block 22, prevent lateral displacement, and improve the stability of the rolling support.

[0038] Furthermore, a top connecting shaft 3 connected to the base plate 1 is installed on the top of the wheel bracket 2. The base plate 1 is formed with a rotating hole 31 for the top connecting shaft 3 to be inserted. Through the rotational connection between the top connecting shaft 3 and the rotating hole 31, the entire auxiliary wheel module can rotate, and the base plate 1 with the luggage box installed can turn and change different directions of movement.

[0039] Furthermore, the top connecting shaft 3 is fitted with a first rolling bearing 32 and a second rolling bearing 33, wherein the first rolling bearing 32 is located at the bottom of the rotating hole 31, and the second rolling bearing 33 is located at the top of the rotating hole 31. After the top of the top connecting shaft 3 is inserted into the rotating hole 31, a limiting plate is installed on the top of the top connecting shaft 3 to prevent the top connecting shaft 3 from disengaging from the rotating release hole. In addition, by setting the first rolling bearing 32 and the second rolling bearing 33, the top rotating shaft can rotate stably within the rotating hole 31, and can smoothly turn even when carrying heavy items.

[0040] The top connecting shaft 3 has a hollow hole 34 formed along the axial direction, and the wheel bracket 2 has a rotating shaft mounting groove 35 for mounting the top connecting shaft 3. The bottom of the rotating shaft mounting groove 35 has a bottom mounting hole 36 that is coaxially aligned with the hollow hole 34. The bottom of the top connecting shaft 3 is inserted into the rotating shaft mounting groove 35 of the wheel bracket 2, so that the hollow hole 34 of the top connecting shaft 3 is coaxially aligned with the bottom mounting hole 36 of the rotating shaft mounting groove 35. Then, bolts are inserted to fix the top connecting shaft 3 to the rotating shaft mounting groove 35. When the top connecting shaft 3 rotates, the wheel bracket 2, on which the driven wheel body 21 is mounted, can rotate to achieve stable steering.

[0041] It should be noted that the active wheel module 11 is a power wheel. The active wheel module 11 leads wires to the base plate 1. The circuit module in the base plate 1 supplies power to the active wheel module 11. The power wheel is a common powered structure in suitcases. After being powered on, the power wheel can rotate. The specific structure and functional principle of the power wheel will not be elaborated here. It can realize the active movement of the base plate 1, reduce the effort required to drag the suitcase, and achieve the effect of saving time and effort.

[0042] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
