DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figures 1 to 3 This embodiment discloses an electric luggage case with driven wheels, comprising a case body 1, a front wheel assembly mounted on the bottom of the case body 1, and a rear wheel assembly. The rear wheel assembly comprises one rear wheel 2 or multiple rear wheels 2 arranged transversely. Specifically, when there are multiple rear wheels 2, at least two of the multiple rear wheels are arranged transversely. The number of rear wheels 2 is typically 2-4. The front wheel assembly includes a driving wheel 5, flanked by driven wheels 7. The driving wheel 5 is typically a hub motor.

[0023] Wherein, the lateral side of the driving wheel 5 is provided with at least one driven wheel 7, and the driven wheel 7 adopts a detachable, foldable or retractable connection relative to the driving wheel 5. In the present embodiment, the driven wheel 7 and the driving wheel 5 are preferably designed to be detachable.

[0024] Specifically, the driving wheel 5 is mounted on the driving wheel fork 9 via the driving wheel shaft 51, and the driven wheel 7 is mounted on the driving wheel shaft 51. The driven wheel 7 is provided with a driven wheel shaft 6, which is threadedly connected to the driving wheel shaft 51. In other words, the end of the driving wheel shaft 51 has an extra threaded section, and the end of the driven wheel shaft 6 has a corresponding threaded hole. The threaded hole can be threadedly connected to the end of the driving wheel shaft 51.

[0025] The driven wheel shaft 6 is further provided with a tool connecting section 61 for rotating the driven wheel shaft 6. The tool connecting section 61 facilitates the removal or installation of the driven wheel shaft 6. The tool connecting section 61 is generally flat in design for cooperation with a wrench.

[0026] Furthermore, the driven wheel shaft 6 can also be detachably mounted on the driving wheel fork 9, for example, by being connected via threads or screws.

[0027] This embodiment further includes a telescopic bracket 4 and a driving wheel stem 3 connected to the front end of the telescopic bracket 4 . The telescopic bracket 4 can be telescoped relative to the box body 1 . The driving wheel 5 is installed below the driving wheel stem 3 .

[0028] The side of the housing 1 is provided with a stem storage slot 11. The side profile of the driving wheel stem 3 matches this slot. When the driving wheel stem 3 is placed within the stem storage slot 11, the driving wheel 5 is at a return angle. The cross-section of the stem storage slot 11 is designed to be an isosceles trapezoid, narrow at the bottom and wide at the outside. The cross-section of the driving wheel stem 3 matches this. When the driving wheel stem 3 is stored within the stem storage slot 11 via the telescopic bracket 4, the driving wheel 5 is at a return angle within the constraints of the isosceles trapezoidal profile. The so-called return angle refers to the position in which the driving wheel is not turning, which is the position shown in the accompanying figure.

[0029] In this embodiment, a pedal portion 8 is further provided below the driving wheel handle 3 .

[0030] Compared to the prior art, this embodiment reduces the possibility of the luggage body 1 tipping over during riding by designing a driven wheel 7 in place of the driving wheel, thereby improving the safety of the luggage case. The driven wheel 7 in this embodiment is detachable and can be removed and stored when not in use, thus improving the flexibility of use.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
