Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail.

Consult Fig. 1, the utility model multifunctional baby rocking chair is mainly by base 10, seat support 20 and drive unit 30 constitute, wherein base 10 is a rectangle car body, has wheel 11, and a positioning rod 12 is respectively established in both sides, the base rear is provided with brake 13, slide so that when rocking chair shakes, prevent car body, and base 10 the place aheads are provided with a pivot 14 that is connected with seat support 20 front ends, above base, are provided with a spring 15 that is used to support seat support 20 weight.

Seat support 20 is

Type, its top is provided with handrail 21, across in its both sides, seat support 20 rear ends also are provided with a concealed handle 23 except that being provided with a shrinkable sunshade 22, seat support 20 both sides respectively are provided with two locating holes 24, when rocking chair is used as go-cart (consulting Fig. 2), the backstay 12 that is about to base 10 both sides is fixed with this locating hole 24, and pulls out handle 23, remove the locking-in state of brake 13, just can normally use.

Be configured in base 10 rear sides by one, and the upper end is connected the drive unit 30 of seat support 20 belows, it is converted into turning moment and makes seat support 20 motion that teeters.

Consult Fig. 3, described drive unit 30 provides turning moment by a direct current motor 310, drive bigger driven wheel 312 by connected pinion 311, this design is except that slowing down the rotary speed, also can provide bigger force arm, this driven wheel 312 is by a bearing 313, external screw thread 315 on nut 314 and a strip driving shaft 320 1 ends screws togather, these driving shaft 320 central authorities are provided with two bulge loops 321, the other end is provided with a groove 322, with a snap ring 325 and bearing 323 actuating arm 324 is fastened on this groove 322, in addition, driving shaft 320 belows are provided with a shock absorber 330, and it is entrenched in the square groove 331 by a pad 333 and spring 332, the vibrations of generation when rotating in order to absorb driving shaft 320, and reduce noise.

Actuating arm 324 outer ends are provided with a screw 329, be locked together in screw 328 places that a strip is taken over 341 lower ends by a screw 326 and nut 327, this adapter 341(is a fast connecting joint) both sides each will block with screw 342 and fill up 343, trip 344 and spring 345 are locked in draw-in groove 340 places that take over 341 upper ends, can be fastened on a cylindrical revoling tube 350 lower ends with taking over 341, the inboard, upper end of this revoling tube 350 is provided with internal thread 352, screwed togather by the external screw thread of a location nut 351 with screw thread cylinder 360, and a retainer ring 346 holdings are in the groove 366 of screw thread cylinder 360 lower ends, to prevent that revoling tube 350 and screw thread cylinder 360 break away from, and these screw thread cylinder 360 outer surfaces are provided with a scale groove 362, with as the sign that screws togather the degree of depth.Use a screw 364 again, nut 365 and be arranged on the screw 363 of screw thread cylinder 360 upper ends connects whole drive unit 30 and is fixed on seat support 20 belows.

(see figure 4) when turning arm 324 rotation is downward, just with the seat support 20 traction bottoms, when turning arm 324 rotations upwards the time, the restoring force that adds upper spring 15 then will make seat support 20 push to raise up, circulation so repeatedly, thus realized the Automatic rocking chair function that swings up and down.
