This utility model belongs to the field of trolley technology, and specifically relates to a trolley that facilitates straight-line travel. It includes a balance scooter and a trolley body, connected by a connecting frame. The connecting frame is detachably connected to the trolley body and rotatably connected to the balance scooter. The balance scooter has a positioning groove, and the connecting frame has a positioning element and an elastic element. The elastic element drives the positioning element to engage with the positioning groove, fixing the balance scooter and the connecting frame relatively, thus allowing the trolley to maintain straight-line travel or maintain a certain angle of rotation. Under external force, the positioning element can move relative to the positioning groove, allowing the balance scooter and the connecting frame to rotate relative to each other, thus enabling the trolley to turn flexibly. The purpose of this utility model is to provide a user-friendly trolley that facilitates straight-line travel.

This invention discloses a modular smart bag that is deformable and adaptable to multiple scenarios, belonging to the field of smart bag technology. It includes an outer box and a box mechanism for placing items. The outer box is equipped with a folding mechanism for switching usage modes and a moving mechanism for movement. This invention integrates a traditional single-function bag into a multi-purpose smart device. It can quickly transform into various forms as needed, such as a modular storage box, a smart cargo vehicle with a seat, a large-capacity transport box, and an outdoor camping base. Users do not need to prepare multiple special equipment for different scenarios. The folding and unfolding seat mechanism of this invention uses multi-level rotating joints and multiple pin modules for multi-point adjustable locking. Combined with the steering system formed by the extendable upright rotating rod and the hand grip column, the user can stably control the movement and steering of the box while riding, transforming the bag from a passive dragging item into an active and controllable portable vehicle.
