In summary, the beneficial technical effects of the utility model are as follows:

compared with the prior art, the infant care equipment provided by the utility model has the advantages that the horizontal reciprocating mechanism and the vertical reciprocating mechanism are arranged, so that the supporting device can reciprocate back and forth in at least two dimension directions, when the supporting device supports an infant, the infant care equipment can effectively simulate the movement of an infant care person when the infant care person is in care of the infant, on one hand, the infant care equipment plays roles of pacifying and pleasuring the infant, on the other hand, the pressure of the infant care person is reduced, and the infant care equipment is worthy of popularization. When the vertical reciprocating motion mechanism drives the supporting device to do vertical reciprocating motion, the lifting piece is limited to rotate by the installation cover, friction is generated between the installation cover and the lifting piece, but noise generated by the friction is small, so that the influence of the noise on the infant is reduced, and the experience of taking care of the infant is improved.

The lifting cylinder is sleeved with the driving sleeve so as to be driven to be vertical by the driving sleeve; reciprocating back and forth. The driving sleeve is provided with a driving groove which can be a thread groove or a ring groove with a gradient, and when the driving groove is the thread groove, the driving sleeve reciprocally rotates back and forth in two directions so as to drive the lifting cylinder to vertically reciprocally move back and forth; when the driving groove is a ring groove with a gradient, the driving sleeve rotates in one direction to drive the lifting cylinder to do vertical reciprocating motion. When the driving groove is a ring groove, at least two driving grooves are arranged for improving the balance and stability of lifting motion of the lifting cylinder and reducing noise, at least two sliding pieces are correspondingly arranged on the lifting cylinder, two adjacent sliding pieces in the at least two sliding pieces are positioned on two sides of the lifting cylinder, and the at least two sliding pieces are correspondingly clamped in the at least two driving grooves; in order to reduce friction between the driving groove and the sliding piece, the sliding piece can adopt a roller or a bearing, so that further noise reduction is realized.

The first rolling piece is arranged between the lifting cylinder and the fixed shaft, and is a linear bearing, so that on one hand, sliding friction between the lifting cylinder and the fixed shaft is changed into rolling friction to reduce noise, and on the other hand, the axis of the lifting cylinder and the axis of the fixed shaft are positioned on the same straight line, and noise between the lifting cylinder and the fixed shaft is further reduced. A second rolling element is arranged between the driving sleeve and the connecting piece of the mounting cover, and the second rolling element is a bearing, so that sliding friction between the driving sleeve and the connecting piece of the mounting cover is changed into rolling friction, friction is reduced, and noise is reduced; a third rolling element is arranged between the driving sleeve and the connecting sleeve of the fixed seat, the third rolling element is a bearing, and the third rolling element changes sliding friction between the driving sleeve and the connecting sleeve into rolling friction so as to reduce friction and noise. Because the axis of the second rolling element and the axis of the third rolling element are positioned on the same straight line, and because the axis of the second rolling element and the axis of the first rolling element are positioned on the same straight line, the axis of the lifting cylinder, the axis of the driving sleeve and the axis of the fixed shaft are positioned on the same straight line, on one hand, the stability and the balance of the lifting cylinder driven by the lifting sleeve to do vertical reciprocating motion are improved, on the other hand, the noise is reduced, and on the other hand, the energy consumption of the lifting cylinder driven by the driving sleeve to do vertical reciprocating motion is effectively reduced, so that the effect of saving energy is achieved.

The lifting rod passes through the through hole and extends out of the mounting cover, and the through hole is positioned outside the connecting groove, so that the mounting cover plays a role in limiting the rotation of the lifting cylinder through the through hole and the lifting rod; a limiting component is arranged between the mounting cover and the lifting cover, on one hand, the limiting component limits the lifting cover to rotate relative to the mounting cover, so as to limit the lifting cylinder to rotate, and the lifting cylinder and the lifting cover can only do vertical back and forth reciprocating motion; on the other hand, the limiting component changes sliding friction between the lifting cover and the mounting cover into rolling friction so as to reduce noise; because the spacing subassembly includes three at least first sliders of group and three at least second sliders of group, three at least first sliders of group and three at least second sliders of group are located between lift cover and the installation cover, and three at least first sliders of group and three at least second sliders interval sets up, and the second slider is located the top of first slider for stability and equilibrium when lift cover and lift are vertical back and forth reciprocating motion for the installation cover to promote the experience of taking care of infant. Because there is the clearance between pore wall and the lifter of through-hole to reduce friction between through-hole and the lifter, be favorable to the noise reduction.

An elastic piece is arranged between the fixed seat and the lifting cylinder, and when the lifting cylinder rises upwards, the elastic piece plays a role in pushing the lifting cylinder to move upwards so as to reduce the number of the lifting cylinders; when the lifting cylinder is lowered downwards, on one hand, the elastic piece plays a role in buffering, so that the lifting cylinder is lifted to move downwards at a speed which is favorable for balancing and stabilizing, and on the other hand, due to the action of the elastic piece, the groove wall of the driving groove positioned at the opposite top is propped against the sliding piece, and the driving sleeve drives the lifting cylinder to move downwards. If the elastic piece is not arranged, on the one hand, the problem that the downward movement speed of the lifting cylinder is too high occurs, the balance is poor in stability, and on the other hand, the sliding piece of the lifting cylinder which vertically reciprocates back and forth is propped against the groove wall of the driving groove positioned at the opposite bottom, so that no new idea exists. When the driving sleeve does not drive the lifting cylinder to rotate, gaps can exist between the sliding piece and the groove walls at the top and the bottom of the driving groove due to the action of the elastic piece.

Further, when driving motor suddenly stops moving, because inertia, the worm still trend turbine rotates, because the lifting cylinder has the trend of downward movement because of the effect of gravity to the lifting cylinder has the trend of driving the driving sleeve to rotate, again because the elastic component restriction lifting cylinder downward movement, makes automatic auto-lock between turbine and the worm, with restriction driving sleeve rotation, is favorable to promoting stability and equilibrium, reduces infant and is frightened because of driving motor suddenly stop work, in order to promote use experience.

The mounting cover clamps the track through the two rollers, so that on one hand, the balance and stability of the mounting cover in horizontal reciprocating motion are improved, and noise is reduced; on the other hand, the separation between the roller and the track can be limited so as to keep the contact between the roller and the track, and the balance and stability of the mounting cover during horizontal reciprocating motion are kept so as to reduce noise; in addition, friction between the roller and the rail is reduced to reduce noise. The sliding block is driven to slide in the sliding groove through the driving disc so as to drive the installation cover to move on the track, and the movement speed of the installation cover can be controlled by controlling the rotation speed of the driving disc so as to control the installation cover to perform balanced and stable horizontal movement.

The safety cover is arranged on the lifting cover and has a gap with the lifting cover so as to reduce friction between the lifting cover and the safety cover and reduce noise; when the lifting cover is lifted to the highest position, the bottom of the lifting cover is positioned below the top of the safety cover so as to limit the clamping injury used when the lifting cover moves in a lifting manner, and the safety coefficient is lifted.
