Description

Technical Field

[0001] The present application relates to the field of cradles, and in particular to a cradle that can imitate the rocking state of a mother. Background Art

[0002] The healthy growth of young children is a major family and social issue. Cradles are essential for a child's development. While these have seen significant development, existing cradles still have significant drawbacks. In particular, their rocking effect is poor, making it difficult to mimic a mother's rocking motion for optimal hypnotic effect. It's not uncommon to find that rocking a child in a mother's arms and arms has two key characteristics: first, the child's head is slightly elevated above the rest of the body, giving the child a sense of security; second, the head moves slightly upward while translating horizontally, creating a height difference that makes the child feel more comfortable and at ease.

[0003] However, most of the currently available electric cradles have a translational motion and do not produce a height difference when shaking, making it difficult to achieve the best hypnotic effect. Summary of the Invention

In this embodiment, the control lock 800 is an electromagnetic lock, which has a retractable lock tongue. By controlling the retraction and extension of the lock tongue, the lock tongue is inserted into and out of the fixed sleeve 620 and the synchronization rod 610 in turn, thereby realizing the locking and unlocking of the fixed sleeve 620 and the corresponding synchronization rod 610. Since the electromagnetic lock is a prior art, its specific structure will not be repeated here.

[0049] The cradle that can imitate the rocking state of the mother provided in the embodiment of the present application can realize functions such as rocking imitating the mother's movements, cradle braking, cradle folding, cradle sitting and sleeping position adjustment, stair climbing and stair climbing locking, so as to facilitate users to take infants and young children out for use.

[0050] When the cradle that can imitate the mother's rocking state imitates the mother's action of rocking, the rocking motor 350 in the control box 310 is started, and the output shaft of the rocking motor 350 drives the intermediate connecting rod 352 to rotate, thereby driving the driving wheel 380 to rotate, so that the driving wheel 380 moves along the strip groove 370 provided on the driving rod 360, thereby pushing the driving rod 360 to perform a fan-shaped motion around the axis of the connecting shaft 390, and then causing the rocking crank 330 to swing in a fan-shaped manner around the axis of the connecting shaft 390, and the rocking crank 330 drives the door-shaped bracket 320 to move left and right through the short arm 321, and drives the rocking rod 340 to perform a fan-shaped motion with the hinge of the rocking rod 340 and the control box 310 as the center of the circle through the long arm 322 of the door-shaped bracket 320. When the door-shaped bracket 320 moves left and right, it drives the door on the other side through the connected cradle 200. The gate-shaped bracket 320, the rocking crank 330 and the corresponding rocking rod 340 move synchronously. At this time, since the long arm 322 of the gate-shaped bracket 320 is longer than the short arm 321, the movement radius of the short arm 321 will be smaller than the movement radius of the long arm 322. When the long arm 322 swings left and right within the translation range, the short arm 321 will move up and down while moving in translation. When the child is placed in the cradle 200 with the head close to the side of the short arm 321 and the feet close to the side of the long arm 322, the cradle 200 drives one end of the child's head to move back and forth along the trajectory of translation-upper left-stop-lower right-translation, and the middle part and legs of the cradle 200 perform approximately translational movement, thereby imitating the sleeping state of the child being rocked in the mother's arms, thereby achieving a "bionic" hypnotic effect and helping the child fall asleep quickly. The drive rod 360 and the corresponding crank arm 330 are hingedly connected by a connecting shaft 390. A first torsion spring 391 is mounted on the connecting shaft 390. The ends of the first torsion spring 391 are connected to the drive rod 360 and the corresponding crank arm 330, respectively. When the drive rod 360 drives the crank arm 330 to swing in a fan-shaped pattern around the axis of the connecting shaft 390, the elastic action of the first torsion spring 391 causes the initial movement of the crank arm 330 to lag by an angle before gradually synchronizing, thereby achieving a force-buffering and flexible motion effect. When the crank arm 330 encounters external interference, causing its movement to be obstructed, the elastic action of the first torsion spring 391 causes the drive wheel 380 to rotate, only driving the drive rod 360, while the crank arm 330 is in a "slipping" state, preventing it from moving. This prevents damage to the crank motor 350.

[0051] When braking the cradle 200, the user can hold the brake handle 460 extending from the other control box 310 and rotate it. When the brake handle 460 rotates, the cam 450 is driven to rotate. When the cam 450 rotates, the brake push rod 440 is pressed to move in a straight line to push the brake disc 430, one end of which is inserted into the slide groove 420, to move. The brake disc 430 moves along the slide groove 420 until the brake head teeth 480 and the brake disc teeth 490 engage and lock. At this time, the corresponding control box 310 The brake head 410 and the rocking crank 330 connected thereto are locked and fixed, thereby limiting the position of the hinged door-shaped bracket 320 corresponding to the rocking crank 330, and further limiting the position of the cradle 200 to realize the braking function. When the brake needs to be released, the brake handle 460 is rotated in the reverse direction to drive the cam 450 to rotate and stop pressing the brake push rod 440. At this time, the rocking of the cradle 200 can drive the corresponding door-shaped bracket 320 and the rocking crank 330 to move, pushing the brake disc 430 to move in the reverse direction along the slide groove 420 to reset.

[0052] When the cradle 200 of the cradle that can imitate the rocking state of the mother needs to be folded, the user presses the folding pressure rod 580 downward with his foot, and the folding pressure rod 580 rotates downward through the folding connecting rod 581 to drive the locking inner rod 560 to descend along the rear sleeve 520 to squeeze the lock top spring 570. At this time, the top of the descending locking inner rod 560 disengages from the lock plate notch 531 on the bracket lock plate 530, thereby releasing the position lock of the bracket lock plate 530. At this time, the user can push the two control boxes 310 is rotated 180 degrees relative to the front support rod 540 and the rear support rod 550, and the support lock plate 530 is rotated 180 degrees relative to the rear sleeve 520, and the front support rod 540 is rotated 180 degrees relative to the front support 510, so that the two control boxes 310 and the cradle 200 connected thereto are rotated and moved down to be close to the upper surface of the base 100, realizing the downward movement and folding function of the cradle 200, and the large compression can imitate the height of the cradle in the state of being rocked by the mother.

[0053] The footrest 220 can be pressed downward to move the footrest 220 along the hinged part with the bottom wall of the cradle 200 until the footrest strap 240 is pulled into a straight line, and the footrest 220 can be used to support the child's legs, so that the child's legs can be changed from the sleeping position to the sitting position. When the child is changed from the sitting position to the sleeping position, only the reverse operation is required.

[0054] The braking principle of the cradle that can imitate the rocking state of the mother is: in the unbraked state, the second return spring 780 on the second rod body 612 of the synchronization rod 610 pushes the brake movable disc 720 to move to fit the brake positioning seat 710. At this time, the arc groove 790 and the arc block 791 set on the end surface of the brake movable disc 720 and the brake positioning seat 710 are correspondingly slidably fitted. When the user needs to brake, he steps on the brake pad 640, and the brake pad 640 rotates to drive the synchronous rod 610 to rotate. When the synchronous rod 610 rotates, the limiting groove 613 convex on the outer wall of the second rod body 612 and the limiting protrusion 721 inserted into the limiting groove 613 drive the brake movable disc 720 to rotate. At this time, the brake positioning seat 710 is connected and fixed with the fixing sleeve 620 and the corresponding side climbing crank 150 and does not rotate, so that the brake movable disc 720 and the brake positioning seat 710 produce relative rotation, so that the arc block 791 on the end face of the brake movable disc 720 moves along the arc groove 790 on the end face of the brake positioning seat 710 to the arc block 791, so that the brake positioning seat 710 pushes the brake movable disc 720 to move axially along the synchronous rod 610, compressing the second return spring 780 until it fits against the side wall of the corresponding wheel carrier disc 630, and the brake movable disc 720 pushes the wheel carrier disc when pressing against the side face of the wheel carrier disc 630. When the first lever 720 is in the unlocked position, the first lever 720 is locked and the first pin 740 is in the unlocked position, so the first pin 740 is locked and the first pin 740 is locked. When the brake is released, the compressed second return spring 780 pushes the brake movable disc 720 to move in the opposite direction to fit the brake positioning seat 710 and away from the wheel frame disc 630, so that the three wheel frame locking posts 740 connected to the wheel frame disc 630 are respectively disengaged from the three clamping holes on the brake movable disc 720, and the brake movable disc 720 stops pressing against the three second torsion springs 760. The second torsion spring 760 rotates in the opposite direction to reset and stops driving the torsion spring wheel 762 to press against the corresponding rear wheel locking post 750. The compressed first return spring 770 pushes the rear wheel locking post 750 to move in the opposite direction to stop pressing against the corresponding rear wheel 130, thereby releasing the lock on the wheel frame disc 630 and the three rear wheels 130.

[0055] The stair climbing principle of the cradle that can imitate the rocking state of the mother is as follows: during normal use, the user rotates the door-shaped handrail 110 to an angle of about 70 degrees with the base 100, so that the top of the door-shaped handrail 110 is located at one end of the cradle 200, and the second pins 191 connected to the bottom of both ends of the door-shaped handrail 110 are respectively aligned with the second pin holes 192 on the two handrail brackets 190, and then the two second pins 191 are pushed axially to move and insert into the corresponding second pin holes 192, locking the position of the door-shaped handrail 110. At this time, the bottom of both ends of the door-shaped handrail 110 drives the two L-shaped climbing cranks 150 to rotate through the hinged rotating rod 140, so that the fixed sleeve 620 connected to the two climbing cranks 150 drives the sleeved synchronization rod 610 to move to be flush with the plane of the base 100. Figure 1 As shown, at this time, due to the action of gravity, the three rear wheels 130 connected to each wheel frame plate 630 are arranged in an upper and lower arrangement to roll and support the bottom surface, and the user can push the base 100 to move along the bottom surface normally; when it is necessary to climb the stairs, the user needs to rotate the door-shaped handrail 110 to be arranged parallel to the base 100, so that the first pins 170 connected to the two handrail fixing frames 160 are aligned with the first pin holes 180 respectively provided at both ends of the door-shaped handrail 110, and then push the first pin 170 to move axially and insert it into the corresponding first pin holes 180 to fix the position of the door-shaped handrail 110 and the base 100. At this time, the bottom of the two ends of the door-shaped handrail 110 drives the two L-shaped climbing cranks 150 to rotate through the hinged rotating rod 140, so that the fixing sleeve 620 connected to the two climbing cranks 150 drives the sleeved synchronization rod 610 to move to the position below the base 100 as shown. Figure 13 When the user is climbing the stairs, the climbing crank 150 drives the wheel frame plate 630 to rotate due to the pulling force of the front wheels 120 and the door-shaped handrail 110 and the squeezing of the stairs, until the two rear wheels 130 connected to the wheel frame plate 630 roll up and down and press against the side wall of the stairs and no longer move forward. At this time, due to the pulling force of the front wheels 120 and the door-shaped handrail 110, the climbing crank 150 drives the two rear wheels 130 that roll against the side wall of the stairs to roll up and down simultaneously until the rear wheels 130 at the top are suspended in the air. The wheel frame plate 630 rotates to make the rear wheels 130 at the top roll against the top wall of the previous stair and continue to move until the rear wheels 130 at the bottom rise along the side wall of the stairs and roll against the top wall of the previous stair, thereby completing the climbing of one stair. Thereafter, the above action can be repeated to climb the stairs. When going down the stairs, the above reverse procedure can be followed.
