Detailed implementation manners

[0036] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0037] As Figures 1 - 2 shown, an automatic rocking bed for children according to the present utility model includes:

[0038] A rocking bed support seat 21, both sides of the rocking bed support seat 21 are provided with fixed positions, and the left joint structure 23 and the right joint structure 24 are respectively fixed to the fixed positions of the rocking bed support seat 21;

[0039] A rocking bed main body 22, both ends of the rocking bed main body 22 are provided with rotating shaft seats, and the rotating shafts are connected to the rotating shaft rods of the left joint structure and the right joint structure, so that the rocking bed main body 22 can rotate and shake.

[0040] As Figures 3 - 6 shown, the left joint structure includes a button structure, a left joint housing 4, a left joint inner housing, an automatic swing structure, and a clutch gear structure;

[0041] The left joint housing 4 and the left joint inner housing are spliced with each other to form a housing, and the automatic swing structure is arranged between the housings; the button structure is arranged above the left joint housing 4 and corresponds to the clutch gear structure in position; a rocker arm structure is installed in the housing, and the rocker arm structure corresponds to the automatic swing structure.

[0042] In this embodiment, the button structure includes a lower body of the button 1, a button spring 2, and a button cap 3;

[0043] The lower body of the button 1 and the button cap 3 are fixed by screws, one end of the button spring 2 contacts the button cap 3, and the other end of the button spring 2 contacts the left joint housing 4. By pressing or releasing the button cap 3, the lower body of the button 1 can be telescopically moved up and down in the left joint housing 4 and corresponds to the clutch gear structure.

[0044] AsFigures 7 - 8 As shown, the clutch gear structure includes a T-shaped clutch tooth A17 and a T-shaped clutch tooth B7;

[0045] A T-shaped card slot is arranged between the T-shaped clutch tooth A17 and the T-shaped clutch tooth B7 in a matching manner. There are two straight surfaces with different heights on the lower body of the button, and the inclined surface is used to transform the contact with the T-shaped clutch tooth A17;

[0046] Press the button cap to move the lower body of the button downward. By using the inclined surface to push the T-shaped clutch tooth A forward, it engages with the T-shaped clutch tooth B, enabling these two parts to rotate synchronously; Similarly: If the button cap of part 3 is released, the lower body of the button will move upward. Under the action of the T-shaped clutch tooth spring, the T-shaped clutch tooth A and the T-shaped clutch tooth B will separate, making these two parts unable to rotate synchronously.

[0047] In this embodiment, a one-way clutch structure is arranged between the rotating shaft seat of the rocking bed main body 22 and the left joint structure;

[0048] The one-way clutch structure includes a one-way clutch tooth 14 and a clutch tooth arranged opposite to the one-way clutch tooth 14 in a matching manner; When the rocking bed main body 22 rotates forward, the one-way clutch tooth 14 is driven to rotate synchronously by the engaged clutch teeth; The one-way clutch tooth 14 is in gear engagement with the T-shaped clutch tooth B7 to drive the T-shaped clutch tooth B7 to rotate;

[0049] A connecting pin 9 is fixed inside the rotating shaft seat of the rocking bed main body 22. One end of the one-way clutch tooth 14 spring abuts against the connecting pin 9, and the other end of the one-way clutch tooth 14 spring abuts against the one-way clutch tooth 14. When the rocking bed main body 22 is pushed to rotate reversely, the mutually matching one-way clutch structure will push the one-way clutch tooth 14 away from the rocking bed main body 22 and will not drive the one-way clutch tooth 14 to rotate reversely synchronously; When the rocking bed main body 22 is pushed forward again, the one-way clutch tooth 14 spring pushes the one-way clutch tooth 14 to cooperate with the rocking bed main body 22, thereby driving the one-way clutch tooth 14 to rotate.

[0050] As Figures 9 - 14 shown, the automatic swing structure includes a coil spring 11, a coil spring seat 10, a coil spring cover 8, and a coil spring tooth 13;

[0051] The coil spring 11 is assembled in the coil spring seat 10 and is pressed tightly by the coil spring cover 8; A card slot is arranged on the coil spring tooth 13, and the card slot end of the coil spring tooth 13 passes through the coil spring cover 8, and the steel sheet of the coil spring 11 is clamped in the card slot; The coil spring tooth 13 cooperates with the T-shaped clutch tooth A17; When the T-shaped clutch tooth A17 rotates, the steel sheet of the coil spring 11 is tightened by driving the coil spring tooth 13. After the coil spring 11 is tightened to a certain extent, the button cap 3 is released, and the coil spring 11 expands to generate a driving force to drive the coil spring tooth 13 to rotate reversely. At this time, the two T-shaped clutch teeth disengage and will not transmit the rotation to the rocking bed main body 22.

[0052] As shown Figure 15 - in Fig. 17, the rocker arm structure includes a reduction gear 12, a ratchet wheel 18, and a pallet 19;

[0053] The large gear of the reduction gear 12 is engaged with the small gear of the spring winding gear 13, and the small gear of the reduction gear 12 is engaged with the teeth of the ratchet wheel 18; a pallet 19 is arranged in cooperation with the ratchet wheel 18; the rotation of the spring winding gear can drive the ratchet wheel to rotate through the reduction gear; the ratchet wheel is provided with ratchet teeth, and the rotation speed is adjusted by the pallet to achieve slow rotation. At the same time, the pallet can also swing.

[0054] In addition, a rocker arm 20 is axially connected to the pallet 19, and the hole in the middle of the rocker arm 20 is connected by a circular ring groove of the cylinder of the housing joint; the cylinder at the lower end of the rocker arm 20 is inserted into the circular ring groove of the rocker bed main body 22.

[0055] In addition, a fixed partition 15 is arranged between the left joint inner shell and the left joint outer shell 4, and the fixed partition 15 serves to install various internal parts.

[0056] In addition, the torsion spring can be replaced by a spring winding or other structures that can drive the gear to rotate to achieve the same effect.

[0057] The working principle is as follows:

[0058] When the key cap is pressed and the rocker bed swings reciprocally in a cycle by pushing, the spring winding will rotate and wind up; when a certain force is reached, the pushing of the rocker bed stops, the key cap is released, and the spring winding will expand in the reverse direction, driving the rocker bed to swing slowly automatically until the spring winding of the part no longer expands to generate force and the rocker bed stops swinging.

[0059] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
