Problems solved by technology

[0003] Although, the above-mentioned existing "luggage wheel structure that can assist in dragging on the stair surface" allows the back wheel and the lower back wheel to touch the vertical surface of the stairs, so that the box can be dragged at a large corner to reach the box. It can be dragged on the stepped stair surface, but when the suitcase is walking on the stair surface, the user must drag the suitcase upwards at a predetermined oblique angle, so that the back wheels and the lower back wheels are perpendicular to the stairs If the user drags the box upwards in an upright manner or in a way that does not reach the predetermined angle, it will cause a hard-to-drag situation and cause inconvenience in use.

Embodiment Construction

[0025] see figure 1 and figure 2 Shown are the three-dimensional appearance schematic diagram and the exploded schematic diagram of the first embodiment of the present invention, respectively. As shown in the figure, the present invention is a mobile device structure, which at least consists of a carrier 1, a shaft body 11, two connecting rods 2, two first rolling units 3, two second rolling units 4, and two Consisting of two auxiliary wheels 5, when the user pulls the carrier 1, the carrier 1 can use the first and second rolling units 3, 4 to achieve the effect of smoothly crossing stairs and special terrain.

[0026] The above-mentioned carrier 1 can be a basket, a box, a wheelchair, or other props for carrying items. The bottom of the carrier 1 is equipped with a shaft 11 connecting the two connecting rods 2. The shaft 11 is arranged on the two ends of the connecting rod 2. In the middle of the end, or near any end of the connecting rod.

[0027] The connecting rod 2 is...

Abstract

The invention discloses a running gear, comprising a carrier, a shaft, a connecting rod, a first rolling unit, a second rolling unit and an auxiliary wheel; or a carrier, a connecting rod, a first rolling unit, a second rolling unit and a third rolling unit. When the carrier is used to carry goods, the running gear can successfully get across stairs and special places.

Description

Technical field: [0001] The invention relates to a mobile device structure, in particular to a mobile device that enables users to smoothly cross stairs and special terrains when using a carrier to carry objects. Background technique: [0002] Generally existing such as the "trunk wheel structure that can assist in dragging on the stair surface" such as the Taiwan Patent Gazette Application No. 092219654, is provided with a strip-shaped vertical seat extending upwards on both sides of the bottom of the back of the case. There are several wheel seats and several back wheels are set up, and the diameter of each back wheel is set to gradually increase in diameter from top to bottom, that is, there are several back wheels arranged on both sides below the back of the box, and the diameter of the bottom back wheel is The diameter of the back wheel is larger than that of the upper part; through the above-mentioned structure, the back wheel can be attached to the vertical surface of...
