Technical Field

[0001] This utility model relates to the field of omnidirectional wheel technology, specifically a concealed omnidirectional wheel for a trolley case. Background Technology

[0002] A rolling suitcase is a type of luggage equipped with a pull handle and casters. It is convenient and effortless to use, making it widely used for travel. Rolling suitcases typically have casters at the bottom for easy dragging. A search revealed Chinese patent publication number CN209938223U, which discloses a foldable rolling suitcase caster, relating to the field of rolling suitcase technology. This patent solves the problem of casters being easily damaged during transport. The folding structure minimizes the internal space occupied by the casters, increasing the effective volume of the suitcase. While this technical solution allows for folding and storing the casters, they are still exposed after folding, making it easy for impurities and dust carried on the wheels to fall and affect the storage position.

[0003] Chinese patent publication number CN222629022U discloses a vibration damping mechanism for a swivel wheel of a suitcase, specifically relating to the field of swivel wheel technology. The mechanism includes a pulley, with an axle fixedly connected to the center of the pulley. Fixed frames are movably connected to both ends of the axle, and a sliding plate is fixedly connected to the front end of each fixed frame. A fixing device is fixedly connected to the inner wall of the sliding plate. While this technical solution can prevent pulley damage and reduce shock absorption, during use, the third spring used for cushioning is exposed, making it prone to accumulating dust or impurities, thus affecting the spring's lifespan.
