[0035] Referring to FIG. 1 to FIG. 3, the present disclosure discloses a foldable rocking bed, including a base 1, a bed body 2, and two swing bars 3 for connecting the base 1 and the bed body 2, the base 1 is provided with a driving unit 4, the driving unit 4 is an outsourced deceleration motor, the driving unit 4 can drive the swing bars 3 to rotate, thereby achieving the swing bars 3 driving the bed body 2 to swing, the swing bars 3 rock to drive the bed body 2 to swing, so that the bed body 2 can be rocked to improve the comfort of the rocking bed. The driving unit 4 is of course only preferred, and the swing bars of the present application can also be driven by hands to rotate. In the present application, the swing bars have two functions: the first one is for serving as supporting bars for a conventional bed for supporting, and the second one is for serving as swing bars of a rocking bed, thereby achieving a combined function of folding and swing functions of the bed body.

[0036] As shown in the figures, the specific structure is as follows: the bottom ends of the swing bars 3 are rotationally connected to the base 1 through lower connecting shafts 5, and the lower connecting shafts 5 are connected to the driving unit 4, specifically as follows: the lower connecting shafts 5 are fixedly connected to a reduction motor through shaft sleeves, and the lower connecting shafts 5 are rotationally connected to the base 1 through bearings, while the bottom ends of the swing bars 3 have C-shaped holes, and corresponding ends of the lower connecting shafts 5 are C-shaped rods fitted with the C-shaped holes, so that the driving unit 4 can drive the lower connecting shafts 5 and the swing bars 3 to rotate, of course, in the present application, only one driving unit 4 is provided for cost saving, and the lower connecting shafts 5 not connected to the driving unit 4 are directly rotationally connected to the base 1 through the bearings.

[0037] As shown in FIG. 8, the top ends of the swing bars 3 are rotationally connected to upper connecting shafts 6 through middle connecting shafts (not shown in the figures), the upper connecting shafts 6 are rotationally connected to the bed body 2, the upper connecting shafts 6 and the middle connecting shafts are arranged perpendicular to each other, in the above structure, the upper connecting shafts 6 have shaft bases 7 at one end, the top ends of the swing bars 3 are provided with top grooves 8, the shaft bases 7 are provided with shaft holes 9 thereon, the middle connecting shafts are in running fit with the shaft holes 9 through bearings, groove walls of the top grooves 8 are provided with mounting holes 10 thereon, the middle connecting shafts and the mounting holes 10 are fixedly connected, and the upper connecting shafts 6 are rotationally connected to the bed body 2 through bearings.

[0038] In the present application, the middle connecting shafts are arranged horizontally, while the upper connecting shafts 6 are arranged vertically, the lower connecting shafts 5 are arranged obliquely, an angle of inclination is preferably an acute angle, and because the lower connecting shafts 5 are arranged obliquely, the two swing bars 3 are arranged in parallel and obliquely;

[0039] when the driving unit 4 drives the swing bars 3 to reciprocally rotate, between each set of lower connecting shafts 5, a distance between each set of upper connecting shafts 6 is unchanged, angles between the upper connecting shafts 6 on left and right sides of the bed body 2 and the bed body 2 are fixed, at the same time, the upper connecting shafts 6 swing left and right with respect to the swing bars 3 through the middle connecting shafts, enabling the bed body 2 to smoothly swing left and right with the swing bars 3, moreover, a bottom surface of the bed body 2 is always swung parallel to the ground, the upper connecting shafts 6 can rotate about the middle connecting shafts with respect to the swing bars 3, thereby enabling the bed body 2 to periodically rise and fall, enabling the bed body 2 to swing at the same time while generating height changes, and thus improving comfort of the rocking bed.

[0040] As shown in FIG. 4 to FIG. 7, the bed body 2 is provided thereon with snap fasteners 11 to which the swing bars 3 are clamped, thereby limiting relative swing of the bed body 2 and the swing bars 3.
