Description

Technical Field

[0001] The utility model relates to a luggage case, in particular to a pressure-sensing electric luggage case. Background Art

[0002] A luggage case is a containing device for holding luggage items. With the increase in people's outdoor activities, various types of luggage cases have emerged, including electric luggage cases. Existing electric luggage cases usually only have the function of automatic walking. Due to the limited load-bearing capacity of the luggage case, they do not have the ability to carry people. Moreover, existing luggage cases only have one pull rod, and when pushing or pulling the luggage case, an external force needs to be applied to the pull rod to control the walking direction. If the user rides on the luggage case, it is impossible to apply an external force to the pull rod, nor can the walking direction be controlled. It can be seen that it is very difficult for existing electric luggage cases to achieve the function of safely and reliably carrying a human body. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a pressure-sensing electric luggage case that is convenient to control the walking direction, can automatically sense a human body, and is safe and reliable, aiming at the deficiencies of the prior art.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions.

[0005] A pressure-sensing electric luggage case includes a box body. Electric wheels and driven wheels are provided at the bottom of the box body.

The controller 6 is used to drive the electric wheel 2 to operate according to the start signal fed back by the start-stop control pedals 7 when the pressure signal fed back by the pressure sensor 8 reaches a set threshold value.

[0019] In the above structure, the electric wheel 2 and the driven wheel 3 are both installed at the bottom of the box body 1. The electric wheel 2 is installed at the front end of the box body 1, and the two driven wheels 3 are installed at the rear end of the box body 1. Correspondingly, an armrest mechanism 4 is provided at the front end of the box body 1, and a telescopic pull rod 5 is provided at the rear end of the box body 1. When the user pushes or pulls the luggage and walks, the user can hold the telescopic pull rod 5 and walk in the traditional pushing and pulling manner of a trolley case; when the user needs the luggage to move electrically, the user needs to sit on the top of the box body 1 first. The pressure sensor 8 senses the human pressure and feeds the sensed signal back to the controller 6. When the controller 6 receives the pressure signal and when the pressure reaches the set threshold value, it means that the user has sat firmly on the luggage.
