Compared with the prior art, the present disclosure provides the child care apparatus including the horizontal reciprocating motion mechanism and the vertical reciprocating motion mechanism, the horizontal reciprocating motion mechanism and the vertical reciprocating motion mechanism enable the supporting device to reciprocate back and forth in at least two dimensions. When the supporting device supports infants and toddlers, the child care apparatus is capable of effectively imitating movements of caregivers of the infants and the toddlers when caring the infants and the toddlers, on one hand, the child care apparatus pacifies and pleases the infants and the toddlers, on another hand, the child care apparatus reduces pressure of the caregivers of the infants and the toddlers, which is worthy of popularization. When the vertical reciprocating motion mechanism drives the supporting device to do vertical reciprocating motion, since the mounting cover limits the lifting component to rotate, friction is generated between the mounting cover and the lifting component, but noise generated by the friction is small, so that influence of the noise on the infants and the toddlers is reduced, and experience of caring the infants and the toddlers of the caregivers of the infants and the toddlers is improved.
The lifting cylinder is sleeved with the driving sleeve, so that the lifting cylinder is driven by the driving sleeve to do the vertical reciprocating motion. The driving sleeve includes the driving grooves, and each of the driving grooves may be the threaded groove or the annular groove having the slope, and when the driving grooves are threaded grooves, the driving sleeve reciprocates back and forth in two directions to drive the lifting cylinder to do the vertical reciprocating motion; and when the driving grooves are annular grooves having slopes, the driving sleeve rotates in one direction to drive the lifting cylinder to do the vertical reciprocating motion. When the driving grooves are annular grooves, in order to improve balance and stability of lifting motion of the lifting cylinder and reduce noise, the at least two driving grooves are provided, and the lifting cylinder respectively includes the at least two sliding components, adjacent two of the at least two sliding components are located at two sides of the lifting cylinder, and the at least two sliding components are respectively clamped in the at least two driving grooves. In order to reduce friction between the at least two driving grooves and the at least two sliding components, the at least two sliding components may be rollers or bearings, thereby further reducing noise.
The at least one first rolling component is disposed between the lifting cylinder and the fixing shaft, and the at least one rolling component is a linear bearing. On one hand, sliding friction between the lifting cylinder and the fixing shaft is changed into rolling friction so as to reduce noise, and on another hand, the axis of the lifting cylinder and the axis of the fixing shaft are located on the same straight line, so that noise between the lifting cylinder and the fixing shaft is further reduced. The second rolling component is disposed between the driving sleeve and the connecting component of the mounting cover, and the second rolling component is a bearing, so that sliding friction between the driving sleeve and the connecting component of the mounting cover is changed into rolling friction to reduce friction, thereby reducing noise. The third rolling component is disposed between the driving sleeve and the connecting sleeve of the fixing base, the third rolling component is a bearing, and the third rolling component changes sliding friction between the driving sleeve and the connecting sleeve into rolling friction, so as to reduce friction, thereby reducing noise. Since the axis of the second rolling component and the axis of the third rolling component are located in the same straight line, the axis of the second rolling component and the axis of the first rolling component are located in the same straight line, the axis of the lifting cylinder, the axis of the driving sleeve, and the axis of the fixing shaft are located in the same straight line, on one hand, stability and balance of the driving sleeve driving the lifting cylinder to do the vertical reciprocating motion are improved to reduce noise, and on another hand, energy of the driving sleeve consumed in a process that the driving sleeve drives the lifting cylinder to do the vertical reciprocating motion may be effectively reduced, which saves energy.
The lifting rod passes through the through hole and extends out of the mounting cover, and the through hole is located outside the connecting groove, so that the mounting cover limits the rotation of the lifting cylinder through the through hole and the lifting rod. The limiting assembly is disposed between the mounting cover and the lifting cover, on one hand, the limiting assembly limits the lifting cover to rotate with respect to the mounting cover, thereby limiting the rotation of the lifting cylinder, so that the lifting cylinder and the lifting cover may only do the vertical reciprocating motion; on another hand, the limiting assembly changes sliding friction between the lifting cover and the mounting cover into rolling friction so as to reduce noise. Since the limiting assembly includes the at least three first sliders and the at least three second sliders, the at least three first sliders and the at least three second sliders are located between the lifting cover and the mounting cover, the at least three first sliders and the at least three second sliders are disposed at intervals, and each of the at least three second sliders is located above each of the at least three first sliders, so that the lifting cover and the lifting component do the vertical reciprocating motion with respect to the mounting cover, and the experience of caring the infants and the toddlers of the caregivers of the infants and the toddlers is improved. Moreover, since the fifth gap exists between the hole wall of the through hole and the lifting rod, friction between the through hole and the lifting rod is reduced, which is beneficial to reducing noise.
The elastic component is disposed between the fixing base and the lifting cylinder, when the lifting cylinder rises upward, the elastic component pushes the lifting cylinder to move upward, so as to reduce energy consumption; when the lifting cylinder is lowered down, on one hand, the elastic component plays a role in buffering, so as to slow down a downward movement speed of the lifting cylinder, which is beneficial to improving balance and stability, on another hand, due to an action of the elastic component, a top groove wall of each of the at least two driving grooves abuts against each of the at least two sliding components, so that the driving sleeve drives the lifting cylinder to move downward. If there is no elastic component, on one hand, a problem that the downward movement speed of the lifting cylinder is too high appears, and the balance and the stability are poor, and on another hand, the at least two sliding components, for doing the vertical reciprocating motion, of the lifting cylinder, abut against a bottom groove wall of each of the at least two driving grooves, and there is no new intention. When the driving sleeve does not drive the lifting cylinder to rotate, there may a gap between the at least two sliding components and the top groove wall of each of the at least two driving grooves and a gap between the at least two sliding components and the bottom groove wall of each of the at least two driving grooves due to an effect of the elastic component.
Furthermore, when the driving motor suddenly stops moving, the worm screw still drives the turbine to rotate due to inertia, and the lifting cylinder has a downward movement trend under an action of gravity, so that the lifting cylinder has a trend of driving the driving sleeve to rotate, and the elastic component limits the lifting cylinder to move downward, so that the turbine and the worm screw are automatically self-locked to limit rotation of the driving sleeve, thereby improving the stability and the balance, and a situation that the infants are frightened due to sudden stop work of the driving motor is reduced, so that user experience is improved.
The mounting cover clamps the at least two rails through the two rollers, on one hand, balance and stability of the mounting cover doing horizontal reciprocating motion are improved, so that noise is reduced; on another hand, the two rollers are prevented from being separated with the at least two rails to keep in contact with the at least two rails, thereby ensuring the balance and stability of the mounting cover doing the horizontal reciprocating motion, so that noise is reduced. In addition, friction between the two rollers and the at least two rails is reduced to reduce noise. The driving disc drives the sliding block to slide in the sliding groove, so that the mounting cover is driven to move on the at least two rails, and a moving speed of the mounting cover may be controlled by controlling a rotation speed of the driving disc, which is convenient for controlling the mounting cover to stably do horizontal motion.
The safety cover covers the lifting cover, the fourth gap exists between the safety cover and the lifting cover, so as to reduce friction between the lifting cover and the safety cover, thereby reducing noise. When the lifting cover rises to the highest position, the bottom of the lifting cover is located below the top of the safety cover, so as to prevent the infants and the toddlers from being damaged by the lifting cover when the lifting cover does lifting motion, thereby enhancing a safety factor of the child care apparatus.
