Specifically, the child product of the present invention may be a baby hammock, a hammock, or the like, and the supporting device 200 may be a sleeping basket, a seat pocket, or any other device that a child can lie, sit, or stand in, such that when the child sits on the supporting device 200, the child and the supporting device 200 can pull down the elastic member 300 to a stretched state by its own weight, and then the elastic force of the elastic member 300 reacts to the supporting device 200, such that the supporting device 200 can swing up and down, thereby increasing the enjoyment and comfort of sitting.

In order to enable the supporting device 200 to continuously swing up and down without the need for the adult to apply an external force to one side from time to time, the child product in this embodiment further includes a swing switching mechanism that switches the elastic member 300 between the compressed state and the stretched state.

In this embodiment, the child article is a baby hammock, and the supporting device 200 is a sleeping basket. The support 100 includes a base frame 101 supported on the ground or other plane, a support rod 102 extending from the base frame 101 in an upward bending manner, and a swing mechanism support 103 provided on the top of the support rod 102, wherein a swing mechanism is disposed on the swing mechanism support 103. The supporting device 200 comprises a connecting rod 201 which is bent upwards and extends from one side of the sleeping basket, the lower end part of the elastic piece 300 is connected to the upper end part of the connecting rod 201, the upper end part of the elastic piece 300 is connected to the first connecting position of the swing mechanism support 103, wherein the elastic piece 300 specifically adopts a spring, and the spring is a cylindrical spring and can stretch and retract along the length direction of the spring. The projection of the elastic member 300 in the vertical direction is approximately located at the middle of the sleeping basket, so that the stability of the children product can be ensured. In other embodiments, a plurality of support rods 102 and a plurality of connecting rods 201 can be provided, so as to further improve the stability of the children product, and the connecting rods 201 can also be replaced by flexible ropes.

It should be noted that, because the elastic member 300 has a length and flexibility, the supporting device 200 can also swing horizontally within a certain range, and in order to limit the horizontal swing range of the supporting device 200 and prevent the children products from toppling over due to unstable center of gravity or the supporting device 200 colliding with the bracket 100, the lower portion of the swing mechanism bracket 103 is further provided with a limiting structure 5, specifically, a ring, through which the lower portion of the elastic member 300 passes.

Referring to fig. 2, in this embodiment, the swing conversion mechanism includes a traction cable 1 extending in an up-and-down direction, a lower portion of the traction cable 1 is connected to an elastic member 300, the traction cable 1 is connected to a second connection position on the elastic member 300, the second connection position is located below the first connection position and is spaced apart from the first connection position, the second connection position is specifically located at an intermediate position in a length direction of the elastic member 300, the traction lock 1 may be made of a flexible or rigid material, and may or may not have elasticity, and the invention is not limited thereto. The sway conversion mechanism further comprises a drive mechanism for driving the traction cable 1 to move upwards.

Further, the swing conversion mechanism further comprises a connecting element 2, the upper part of the traction cable 1 is connected with the connecting element 2 at a third connecting position, specifically, the connecting element 2 is provided with a connecting end 23, and the traction cable 1 is relatively rotatably wound on the connecting end 23 around the second rotation central line b. The third connecting position has the lowest position and the highest position when moving, and as the traction rope 1 is connected to the middle section of the elastic element 300, when the third connecting position moves from the lowest position to the highest position, the elastic element 300 is converted from a stretching state to a compressing state; when the third connection position moves from the uppermost position to the lowermost position, the elastic member 300 is transformed from the compressed state to the stretched state. The swing conversion mechanism can drive the elastic member 300 to drive the supporting device 200 to move up and down.

Specifically, the driving mechanism includes a driving member 3 and a motor 4, the motor 4 is fixedly disposed on the swing mechanism support 103, and an output shaft of the motor 4 is drivingly connected to the driving member 3, so that the motor 4 can drive the driving member 3 to rotate around a rotation center line a. The driving member 3 has a pushing portion 31, in this embodiment, the pushing portion 31 is an eccentric pin fixed on the driving member 3, and the eccentric pin is disposed at a distance from the rotation center line a and the third connection position.

The connecting piece 2 and the driving piece 3 are rotatably connected around the rotation center line a, but different rotating shafts are arranged between the connecting piece 2 and the driving piece 3 and between the driving piece 3 and the motor 4, the motor 4 cannot drive the connecting piece 2 to rotate, and the connecting piece 2 can freely rotate around the rotation center line a. Referring to fig. 3 to 6, the connecting member 2 has an engaging portion 21 engaged with the pushing portion 31, the engaging portion 21 is located in front of the moving direction of the pushing portion 31, in this embodiment, the engaging portion 21 is an extension fixed to the periphery of the rotating member 2, and the pushing portion 31 can be engaged and abutted against one side surface of the engaging portion 21.

The working principle of the children product in the embodiment is specifically explained as follows:

referring to fig. 3 to 6, when the pushing portion 31 abuts against the engaging portion 21 and pushes the connecting member 2 to rotate clockwise to the third connecting position located at the highest position, due to the eccentric arrangement of the third connecting position and the rotation center line a, the gravity of the elastic member 300 and the supporting device 200 (including a child when the child sits on the connecting member) will pull the connecting member 2 to rotate clockwise rapidly, as shown in fig. 7 to 11, at this time, because the rotation speed of the driving member 3 driven by the motor 4 is relatively slow, the pushing portion 31 disengages from the engaging portion 21, and the elastic member 300 is converted from the compressed state to the stretched state.

Referring to fig. 9 to 13, when the engaging portion 21 rotates to the lowest position first and the pushing portion 31 does not follow the lowest position, the engaging portion 21 will be stationary or slightly swing at the lowest position for a period of time, but the elastic member 300 may not reach a stable state and may have a certain telescopic motion, so that the supporting device 200 still swings up and down.

Referring to fig. 12 to 15 and 6, when the pushing portion 31 also rotates to the lowest position and catches up with the engaging portion 21, the pushing portion 31 will abut against the engaging portion 21 and push the connecting member 2 to rotate upward, the elastic member 300 is switched from the stretching state to the compressing state until the third connecting position moves to the highest position, the above process will be repeated, and the supporting device 200 continuously swings up and down in such a cyclic reciprocating manner.

In this embodiment, the swing speed of the supporting device 200 can be adjusted by the rotation speed of the motor 4, which is very convenient.

Example 2

Referring to fig. 16 to 19, the structure of the children's product in this embodiment is substantially the same as that of embodiment 1, except that in this embodiment, the connecting member 2 is a disc having a rotation center line a as an axis, the disc is provided with an arc-shaped chute 22 having a central angle of 180 ° or more, the engaging portion 21 is disposed at one end of the arc-shaped chute 22, and the eccentric pin shaft is inserted into the arc-shaped chute 22 in a relatively slidable manner.

Of course, in other embodiments, the connecting member 2 may also be a square disk, a three-piece disk, or any other shape, which does not affect the implementation of the present technical solution.
