Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1 to 3, the main body of the wheel structure of the luggage case is provided as a wheel set 1, the wheel set 1 is installed at the bottom of the luggage case 5, and the rotation of the wheel set 1 is utilized to achieve the functions of moving the luggage case 5 and saving labor.

In the present embodiment, the wheel set 1 is divided into a front wheel set 110 and a rear wheel set 120, and as shown in fig. 2, the front wheel set 110 and the rear wheel set 120 are symmetrically installed below the luggage case 5.

Further, the diameters of the front wheel set 110 and the rear wheel set 120 are different, the lower end surface of the luggage case 5 is kept horizontal under the supporting action of the front wheel set 110 and the rear wheel set 120, the diameter of the front wheel set 110 may be larger than the diameter of the rear wheel set 120, or may be smaller than the diameter of the rear wheel set 120, and the embodiment takes the case that the diameter of the front wheel set 110 is smaller than the diameter of the rear wheel set 120 as an example for description, as shown in fig. 2. Due to the wheel set 1 with the larger diameter, when passing through the rugged ground, the wheel set has smaller bumping feeling on the luggage case 5 and has a firm structure; the wheelset 1 of minor diameter, its materials are few, and the cost is low, is fit for the smooth ground of level and smooth and uses, consequently, the different front wheel group 110 of big minor diameter and rear wheel group 120 of this embodiment combination, can make the suitcase 5 of using this wheelset 1 can compromise the use on different ground, has not only reduced the manufacturing cost of wheelset 1, has still improved the life of rear wheel group 120.

Specifically, the diameter of the front wheel set 110 is controlled to be 50-55cm, and the diameter of the rear wheel set 120 is controlled to be 60-80 cm.

In this embodiment, the wheel set 1 comprises a wheel, which is composed of a hub 130 and a wheel skin 140. The wheel skin 140 is wrapped on the arc surface of the hub 130, the wheel skin 140 can increase the friction force with the ground, the wheel skin 140 and the hub 130 are driven to move synchronously by the friction force between the wheel skin 140 and the ground, and the wheel skin 140 is resistant to friction, so that the service life of the wheel is prolonged.

The wheel set 1 is provided with an axle 150, the axle 150 is connected with two wheels, and the two wheels are symmetrically connected to two sides of the axle 150, as shown in fig. 1, specifically, the axle 150 is connected to the hub 130 of the wheel and connected to the hub 130 through a wheel core 3, and two ends of the wheel core 3 are respectively connected to the axle 150 and the hub 130, so as to realize the process that the hub 130 rotates relative to the axle 150.

In this embodiment, the wheel set 1 is provided with the recessed structure 2, the recessed structure 2 is disposed on the opposite sides of the two wheels, the end of the wheel shaft is inserted into the recessed structure 2, the connection surface formed by the wheel shaft 150 inserted into the recessed structure 2 and the wheels is located inside the wheels instead of being exposed outside the wheels, and compared with the connection surface between the wheels and the wheel shaft 150 in the background art, the wheel shaft 150 hidden inside the wheels is more disadvantageous to winding of impurities such as ropes and weeds or locking of substances such as gravel, thereby reducing the probability of the wheels being affected by the substances and being unable to rotate.

Further, the concave structure 2 is arranged on the inner end face of the hub 130, as shown in fig. 1, the concave structure 2 is arranged on the inner end face of the hub 130, which not only saves production materials of the hub 130, reduces the weight of the hub, further reduces the production cost, but also facilitates the injection molding and mold opening process of the hub 130.

In this embodiment, the wheel set 1 is further provided with a wheel cover 4, the wheel cover 4 is connected to the hub 130 of the wheel and is located on the outer end surface of the hub 130, as shown in fig. 1, the wheel cover 4 covers the outer end surface of the hub 130, so that the outer appearance of the wheel set 1 is improved, and meanwhile, small stones and the like can be prevented from entering from the outer end surface of the hub 130 and being clamped in the hub 130.

4 joints of wheel cap are on wheel hub 130, as shown in fig. 3, 4 medial surfaces of wheel cap are provided with trip 6, but trip 6 joint is fixed in on wheel hub 130 to realize the fixed connection of wheel cap 4 and wheel hub 130, and the installation is comparatively convenient, and the installation effectiveness is high.

Although the preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
