Abstract

A child motion apparatus includes an apparatus base, a movable carrier, a seat mount, a motion mechanism, and a seat assembly. The movable carrier is movably disposed on the apparatus base along a sliding direction. The seat mount is rotatably connected to the movable carrier about a rotation axis perpendicular to the sliding direction. The motion mechanism includes a sliding mechanism and a rotating mechanism. The sliding mechanism connects the movable carrier and the apparatus base for sliding the movable carrier relative to the apparatus base along the sliding direction. The rotating mechanism is disposed on the movable carrier and connected to the seat mount for rotating the seat mount about the rotation axis. The seat assembly is detachably connected to the seat mount, so that the seat assembly slides and rotates together with the seat mount.

First claim

What is claimed is:

1. A child motion apparatus, comprising:
an apparatus base;
a movable carrier, comprising a platform and being movably disposed on the apparatus base along a sliding direction;
a seat mount, rotatably connected to the platform about a rotation axis perpendicular to the sliding direction, the seat mount comprising a first engagement structure of a first non-circular structure profile relative to the rotation axis;
a motion mechanism, comprising:
a sliding mechanism, connecting the platform and the apparatus base for sliding the platform relative to the apparatus base along the sliding direction; and
a rotating mechanism, disposed on the platform and connected to the seat mount for rotating the seat mount about the rotation axis; and

a seat assembly, comprising a seat frame and a connection support fixedly connected to the seat frame, the connection support comprising a second engagement structure of a second non-circular structure profile, the first non-circular structure profile matching with the second non-circular structure profile, the connection support being detachably connected to the seat mount by engaging the second engagement structure with the first engagement structure in one of at least two orientations of the connection support relative to the seat mount.

2. The child motion apparatus of claim 1 , wherein the apparatus base comprises a base body, supporting feet, and expanding legs, the supporting feet are fixed on the base body, the expanding legs are detachably connected to the supporting feet, and the movable carrier, and the motion mechanism are disposed in the base body.

3. The child motion apparatus of claim 2 , wherein the expanding leg has a hole, and the supporting feet are inserted into the holes.

4. The child motion apparatus of claim 1 , wherein the seat assembly comprises a bouncing supporting frame connected to the seat frame and having two bottom portions arching toward the seat frame, and when the seat assembly is detached from the seat mount, the seat assembly is supported on a floor through the two bottom portions of the bouncing supporting frame whereby the seat assembly is able to bounce relative to the floor.

5. The child motion apparatus of claim 1 , wherein the seat assembly comprises a rocking supporting frame connected to the seat frame and having two bottom portions bending toward the seat frame, and when the seat assembly is detached from the seat mount, the seat assembly is supported on a floor through the two bottom portions of the rocking supporting frame whereby the seat assembly is able to rock relative to the floor.

6. The child motion apparatus of claim 1 , wherein the sliding mechanism comprises a first link part and a second link part, which are pivotally connected to the platform and the apparatus base respectively and are pivotally connected with each other, and a link length of the second link part is larger than a link length of the first link part.

7. The child motion apparatus of claim 6 , wherein the first link part is a gear wheel, the sliding mechanism comprises a motor and a gear set, and the gear set is kinematically connected to the motor and the gear wheel.

8. The child motion apparatus of claim 7 , wherein the gear set comprises a worm screw and a worm gear meshing with the worm screw, the worm screw is kinematically connected to the motor, and the worm gear is kinematically connected to the gear wheel through a gear meshing.

9. The child motion apparatus of claim 7 , wherein the gear wheel comprises a wheel body and an intermediate part which are rotatable about the same rotation axis relative to the platform, the wheel body has outer teeth and inner teeth, the intermediate part has a paw resiliently engaged with the inner teeth, the gear set is kinematically connected to the gear wheel through the outer teeth of the wheel body, the second link part is pivotally connected to the gear wheel through the intermediate part, and when a force transferred between the paw and the inner teeth exceeds a threshold, the paw slips relative to the inner teeth.

10. The child motion apparatus of claim 1 , wherein the rotating mechanism comprises a first link part, a second link part, and a third link part, the first link part is pivotally connected to the platform, the second link part is pivotally connected to the first link part, the third link part is pivotally connected to the second link part and fixedly connected to the seat mount, a length sum of a link length of the third link part and a distance between the rotation axis and a position where the first link part is pivotally connected to the platform is larger than a length sum of a link length of the first link part and a link length of the second link part, and a length sum of the link length of the second link part and the link length of the third link part is larger than a length sum of the link length of the first link part and the distance.

11. The child motion apparatus of claim 10 , wherein the first link part is a gear wheel, the rotating mechanism comprises a motor and a gear set, and the gear set is kinematically connected to the motor and the gear wheel.

12. The child motion apparatus of claim 11 , wherein the gear set comprises a worm screw and a worm gear meshing with the worm screw, the worm screw is kinematically connected to the motor, and the worm gear is kinematically connected to the gear wheel through a gear meshing.

13. The child motion apparatus of claim 11 , wherein the gear wheel comprises a wheel body and an intermediate part which are rotatable about the same rotation axis relative to the platform, the wheel body has outer teeth and inner teeth, the intermediate part has a paw resiliently engaged with the inner teeth, the gear set is kinematically connected to the gear wheel through the outer teeth of the wheel body, the second link part is pivotally connected to the gear wheel through the intermediate part, and when a force transferred between the paw and the inner teeth exceeds a threshold, the paw slips relative to the inner teeth.

14. The child motion apparatus of claim 1 , wherein the motion mechanism comprises a controller and a control panel electrically connected to the controller, the sliding mechanism comprises a first motor electrically connected to the controller, the rotating mechanism comprises a second motor electrically connected to the controller, and when the controller receives an input operation by a user through the control panel, the controller, according to the input operation, controls the first motor of the sliding mechanism to drive the platform to slide relative to the apparatus base along the sliding direction and the second motor of the rotating mechanism to drive the seat mount to rotate about the rotation axis.

15. The child motion apparatus of claim 14 , wherein the control panel comprises two motion knobs, which are electrically connected to the controller and through which the controller receives the input operation.
