Description

Technical Field

[0001] The invention relates to the technical field of infant care equipment, in particular to an adjustable ventilation baby crib. Background Art

[0002] A crib is a bed for infants and young children. With the development of technology, cribs have more and more functions, especially cribs with automatic rocking function, which can make the crib rock as a whole through mechanical drive to help the baby fall asleep, thus better meeting the needs of infant care.

[0003] In order to solve the problems of unreasonable structural setting and poor working stability of existing baby beds with rocking function, the prior art (Chinese invention patent with announcement number CN105029959B) discloses a rocking device for a baby bed, which drives the bed board to swing back and forth around the connecting rod mechanism through the rotation of an eccentric lever driven by a motor. The overall structure is simple and the stability is high.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Example:

[0034] See also Figure 1-9 The present invention provides a technical solution: an adjustable ventilated baby bed 3, comprising an anti-tilt shell 1, a swing support unit 2 connected to the inside of the anti-tilt shell 1, and a baby bed 3 connected to the swing support unit 2, wherein the swing support unit 2 comprises a front-rear swing component 21 connected to the inner wall of the anti-tilt shell 1 and a left-right swing component 22 connected to the front-rear swing component 21;

[0035] The front-rear swing assembly 21 includes two side plates 211 symmetrically fixed to the inner wall of the anti-roll housing 1, a transverse plate 212 rotatably connected between the two side plates 211, and a driving part 23 fixed to the inner wall of the anti-roll housing 1 for driving the transverse plate 212 to rotate, and the driving part 23 includes a support body 231 fixed to the inner wall of the anti-roll housing 1, a rotating support plate 232 rotatably connected to the upper end of the support body 231, an arc seat 233 fixed to the lower end of the transverse plate 212, an arc slot 234 provided at the lower end of the arc seat 233, a slider 235 slidably connected in the arc slot 234, a column rotatably connected to the upper end of the rotating support plate 232, and a motor 3 fixed to the inside of the support body 231 and having an output shaft fixed to the lower end of the rotating support plate 232, and the upper end of the column is rotatably connected to one side of the slider 235;

[0036] The left and right swing assembly 22 includes two side plates 221 symmetrically fixed to the upper end of the horizontal plate 1 212, a horizontal plate 222 rotatably connected between the two side plates 221, and a driving part 24 fixed to the upper end of the horizontal plate 1 212 and used for driving the horizontal plate 222 to rotate, and the driving part 24 has the same structure as the driving part 1 23.

[0037] Two symmetrical supporting parts 25 are fixedly connected to the inner wall of the anti-roll shell 1, and two supporting parts 25 are also symmetrically fixedly connected to the upper end of the cross plate 212. The supporting parts 25 include a rod body 251, a movable groove 252 opened inside the rod body 251, a slide seat 254 slidably connected in the movable groove 252, and a spring 253 located in the movable groove 252. The upper end of the slide seat 254 passes through the rod body 251 and extends outward. A ball 255 is rotatably connected in the extended end of the slide seat 254. The two ends of the spring 253 are respectively connected to the inner wall of the movable groove 252 and the lower end of the slide seat 254.

[0038] By setting the above scheme, when the motor three works to drive the rotating support plate 232 to rotate, the rotating support plate 232 can rotate on the support body 231, thereby driving the slider 235 to move, so that the slider 235 slides in the arc-shaped slide groove 234. When the slider 235 slides in the arc-shaped slide groove 234, the position of the slider 235 changes, thereby driving the arc seat 233 and the cross plate 1 212 to rotate, and the cross plate 1 212 rotates between the two side plates 1 211 to achieve the swing in the front and back directions. The structure and working principle of the driving part 24 are the same as those of the driving part 1 23. Therefore, when the driving part 24 works, it can drive the cross plate 222 to rotate between the two side plates 221 to achieve the swing in the left and right directions. The front and back swinging assembly 21 and the left and right swinging assembly 22 can make the baby bed 3 have The baby bed 3 is provided with a rocking function in four directions, namely, front, back, left and right. In this way, when the baby is still restless on the rocking bed, the baby can try to use the rocking function. The rocking function is closer to the baby's experience in the mother's womb, which can better soothe the baby and help the baby fall asleep. At the same time, when the horizontal board 1 212 and the horizontal board 222 are rocking, the lower ends of the horizontal boards 1 212 and the horizontal boards 222 will be out of contact with the ball bearings 255. When the horizontal boards 1 212 and the horizontal boards 222 swing, a force will be applied to the ball bearings 255 and the slide 254 to contract the spring 253. The force applied by the spring 253 to the slide 254 can make the slide 254 support the lower ends of the horizontal boards 1 212 and the horizontal boards 222, thereby preventing the baby bed 3 from tilting due to the heavy weight and the center of gravity shifting during the rocking process.

[0039] See also Figure 1 , Figure 4 and Figure 5 The baby bed 3 includes a bed body 31 fixedly connected to the upper end of the second horizontal plate 222, a fence 32 fixedly connected to the upper end of the bed body 31, an opening opened on one side of the fence 32, and a movable door 33 rotatably connected to the inner wall of the opening, and a door pin is fixedly connected to one side of the movable door 33 for inserting into the fence 32 to limit the movable door 33.

[0040] The bed body 31 includes a bed board 311 fixedly connected to the upper end of the horizontal board 222 and a mattress 312 placed on the upper end of the bed board 311, a through slot 313 and a ventilation hole 316 connected to the through slot 313 are opened inside the bed body 31, and a fan 315 is inserted in the through slot 313, and a limiting ring 314 is screwed on the inner wall of the through slot 313 to prevent the fan 315 from falling out of the through slot 313.

[0041] By setting the above scheme, opening the movable door 33 can facilitate placing the baby on the mattress 312 or lifting the baby from the mattress 312, and controlling the fan 315 to work can extract the gas in the through groove 313 and the ventilation hole 316 to the outside or send the external air into the through groove 313 and the ventilation hole 316, thereby achieving a ventilation effect, improving the comfort of the baby, and helping the baby to fall asleep more comfortably.

[0042] See also Figure 6 and Figure 7 There are also two side support parts 34 symmetrically connected inside the bed board 311, and the side support parts 34 include a movable groove 347 opened inside the bed board 311, a side support plate 345 rotatably connected to the inner wall of the movable groove 347, a motor 341 fixedly connected to the inner wall of the movable groove 347, a rotating rod 342 rotatably connected to the inner wall of the movable groove 347, a connecting rod 343 fixedly connected to the outer surface of the rotating rod 342, a connecting rod 2 344 rotatably connected to the other end of the rotating rod 1 342, and a mattress 2 346 fixedly connected to the upper end of the side support plate 345, and the output shaft of the motor 341 is fixedly connected to one end of the rotating rod 1 342, and the other end of the connecting rod 2 344 is rotatably connected to the lower end of the side support plate 345.

[0043] By setting the above scheme, the motor 1 341 is controlled to work and drive the rotating rod 1 342 to rotate. The rotation of the rotating rod 1 342 drives the connecting rod 1 343 and the connecting rod 2 344 to rotate, so as to push the side support plate 345 out of the movable groove 347, and the side support plate 345 is rotated out of the movable groove 347 (similar to the action of turning a book). When the side support plate 345 is rotated out of the movable groove 347, it forms a certain angle with the bed board 311, thereby pushing the baby, turning the baby over, and prompting the baby to lie on his side.

[0044] See also Figure 6 and Figure 8The bed board 311 is also connected to a slope support adjustment part 35, and the slope support adjustment part 35 includes a movable groove 2 351 opened in the bed board 311, a rotating rod 2 355 rotatably connected to the inner wall of the movable groove 2 351, a connecting rod 3 356 fixedly connected to the outer surface of the rotating rod 2 355, a connecting rod 4 357 rotatably connected to the other end of the connecting rod 356, a plate body 358 rotatably connected to the inner wall of the movable groove 2 351, a mattress 3 3582 fixedly connected to the upper end of the plate body 358, and a driving component connected to the inner wall of the movable groove 2 351 for driving the rotating rod 2 355 to rotate, and the other end of the connecting rod 4 357 is rotatably connected to the lower end of the plate body 358.

[0045] The driving assembly includes a second motor 352 fixedly connected to the inner wall of the second movable groove 351, a second sprocket wheel rotatably connected to the inner wall of the second movable groove 351, a first sprocket wheel 354 fixedly connected to the outer surface of the second rotating rod 355, and a chain belt 353 connecting the first sprocket wheel 354 with the second sprocket wheel, and the output shaft of the second motor 352 is fixedly connected to one side of the second sprocket wheel.

[0046] A mounting groove 3581 is provided inside the plate body 358, and a second ventilation hole 3583 connected to the mounting groove 3581 is provided inside the plate body 358 and the mattress three 3582. A second fan 3585 is inserted inside the mounting groove 3581, and a second limiting ring 3586 for limiting the position of the second fan 3585 is screwed onto the inner wall of the mounting groove 3581. A second through groove 359 connected to the second movable groove 351 is provided inside the bed board 311, and a filter is fixedly connected to the inner wall of the second through groove 359.

[0047] The mattress three 3582 is internally connected with an electric heating element 3584.

[0048] By setting the above scheme, the motor 2 352 can drive the connecting rod 356 and the connecting rod 4 357 to rotate, thereby pushing the plate 358 out of the movable groove 2 351, so that the plate 358 is tilted and forms a certain angle with the bed board 311. When the baby sleeps on the parallel plate 358, the driving motor 2 352 works to rotate the plate 358 to lift the upper body of the baby, imitating the natural posture of the baby in the womb, which helps to reduce gastroesophageal reflux, that is, the situation where food and gastric acid flow back from the stomach to the esophagus, helps to reduce swallowing of air, thereby relieving the baby's hiccups, helps to keep the respiratory tract unobstructed, and helps maintain the baby's sleep. The baby's sleeping position, especially for babies who have not yet been able to control it effectively, can also help prevent vomiting. At the same time, the fan 3585 can draw out the gas in the installation groove 3581 and the ventilation hole 3583 or send external gas into the installation groove 3581 and the ventilation hole 3583 to achieve ventilation effect, improve the baby's comfort, and help the baby fall asleep more comfortably. At the same time, the electric heating element 3584 (which has the same working principle as the electric blanket and belongs to the mature existing technology, which will not be repeated here) can also heat up when powered on, so that the mattress 3 3582 has a certain temperature, thereby improving the baby's comfort in cold weather.
