Embodiment Construction

[0038] Relevant technical content and detailed description of the present invention, now cooperate accompanying drawing to explain as follows:

[0039] see figure 1 , is a three-dimensional schematic diagram of the suitcase of the present invention. Such as figure 1 As shown: the auxiliary device for dragging and walking of the luggage case of the present invention is mainly equipped with an auxiliary device 2 on the wheel set 11 of the luggage case 1. Whether the rotation speed of the wheel set 11 is fast or slow is judged by the auxiliary device 2 to determine whether to output the power source; or when the user drags the suitcase 1 and feels that the suitcase 1 is heavy and difficult to drag, he can press the lever 14 The switch unit 3 on the upper side is used to start the auxiliary device 2 to generate power and transmit it to the wheel set 11, so that the user can drag the suitcase 1 more easily and labor-savingly.

[0040] see figure 2 , image 3 , is the perspect...

Abstract

The invention provides an auxiliary device for hauling a trunk. The auxiliary device comprises a power generating unit, a charging unit, a storage unit, a control unit, a driving unit, an actuating unit, a transmission unit and a sensing unit. During hauling the trunk, a wheel set of the trunk generates power so as to drive the power generating unit for power generation, and the output electric power charges the storage unit through the charging unit. Meanwhile, after a signal sensed by the sensing unit is judged by the control unit, if an auxiliary power source is needed, the control unit outputs a control signal to drive the driving unit and the actuating unit drives the transmission unit, and the generated auxiliary power source drives the wheel set through the transmission unit, so that a user can easily haul the trunk in a labor-saving mode.

Description

technical field [0001] The invention relates to a suitcase, in particular to an auxiliary device for assisting a user in dragging the suitcase. Background technique [0002] Modern people are under too much pressure due to busy work.
