Embodiment Construction
[0035] A stroller for children comprises a vehicle frame 1 and a wheel universal structure connected with the vehicle frame 1 . The children's stroller can be a three-wheeled stroller or a four-wheeled stroller. When it is a three-wheeled stroller, the frame 1 of the three-wheeled stroller includes a front bracket and a rear bracket that are provided with a wheel universal structure at the front bottom. The wheeled cart also includes two sets of rear wheel assemblies arranged at the rear and lower part of the rear bracket. When the wheel universal structure is used as the front wheel assembly of the three-wheeled cart, it can adjust the positional relationship between the landing point of the front wheels and the center plane of the frame. Of course, the wheel universal structure can also be used as other wheel components that need to realize wheel steering.
[0036] As shown in the accompanying drawings, a wheel universal structure includes a wheel 2, a wheel seat 3 that is r...

(b) The invention relates to a wheel universal structure and a child cart, wherein the wheel universal structure comprises wheels, a wheel seat and a connecting mechanism which is used to connect the wheel seat and a frame, the connecting mechanism comprises a swing rod component, a sliding component and a base, the end portion of the swing rod component is fixedly connected with the wheel seat, the sliding component is rotatably connected with the wheel seat, the base is fixedly connected with the frame, the base comprises a first element and a second element, the first element extends along the left-right direction, the second element extends along the front-back direction, the other one end portion of the swing rod component is matched with the second element, and slides relative to the second element along the front-rear direction, the sliding component is matched with the first element and slides relative to the first element along the left-right direction, and when the other one end portion of the swing rod component and the sliding component respectively slide by being matched with the second and the first elements, the wheels and the wheel seat can steer. The wheel universal structure and the child cart can reduce the distance from landing places of the wheels and the center surface of the frame when the wheels steer, thereby being capable of excellently guaranteeing the stability of the child cart. ( / b).
Description
technical field [0001] The invention relates to a wheel universal structure and a stroller for children. Background technique [0002] In the wheel connection structure of baby carriages in the prior art (for example, the publication number is CN103029739A, and the publication date is 2013-4-10), the wheels are installed on a connecting frame, and the connecting frame is rotatably connected to the The bottom of the frame of the stroller enables the wheels to rotate in all directions around the rotation axis. Because traditional children's three-wheel strollers all adopt the above-mentioned wheel connection structure, when the front wheels rotate universally, the landing position of the front wheels deviates from the center plane of the vehicle frame, which seriously affects the stability of the stroller. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wheel universal structure with different structures and a s...
