DETAILED DESCRIPTION OF THE INVENTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0019] In order to solve the problem that the existing baby crib cannot adjust the height of its guardrail and the length of the crib body according to the usage requirements during use.

[0020] Please refer to Figure 1 、 Figure 3 and Figure 5 As shown, the present invention provides a technical solution: a baby crib with adjustable height and length, including a crib body 1. An annular groove 5 is opened on the upper end surface of the crib body 1. An activity plate 6 and a lifting assembly 3 are arranged in the annular groove 5. The annular groove 5 is opened in the annular guardrail of the crib body 1. The activity plate 6 is in sliding contact with the annular groove 5. The lifting assembly 3 is connected to the activity plate 6. The lifting assembly 3 is used to drive the activity plate 6 to slide out or slide into the annular groove 5 to change the height of the crib body 1.

[0021] The crib body 1 includes a first sub-crib body 101 and a second sub-crib body 102. An adjustment assembly 7 is arranged between the first sub-crib body 101 and the second sub-crib body 102. The adjustment assembly 7 is used to drive the first sub-crib body 101 and the second sub-crib body 102 to approach or move away from each other to change the length of the crib body 1.

[0022] In this device, the height of the guardrail of the crib body 1 is lower than that of the crib body 1 in the prior art, so that in this device, when the lifting assembly 3 drives the activity plate 6 to descend and contract in the annular groove 5, the guardian can easily contact the baby, so as to change the baby's clothes and feed the baby.

[0023] When the baby is sleeping or the baby is freely moving in the crib body 1, the lifting assembly 3 drives the activity plate 6 to rise and extend out of the annular groove 5. The activity plate 6 is equivalent to the guardrail, so as to achieve the purpose of increasing the height of the guardrail of the crib body 1 to prevent the baby from climbing over the guardrail and falling and getting hurt when playing.

[0024] Furthermore, as the baby grows and the baby's height increases, the guardian drives the first sub-crib body 101 and the second sub-crib body 102 to move away from each other through the adjustment assembly 7, so that the overall length of the crib body 1 is increased to adapt to babies of different body types.

[0025] In order to realize the driving of the lifting assembly 3 for the rising and falling of the activity plate 6, refer to Figure 1 and Figure 2As shown, in this embodiment, the lifting assembly 3 includes an air pump 301 installed on the bed body 1. A plurality of telescopic air bags 303 are arranged between the bottom of the movable plate 6 and the inner bottom wall of the annular groove 5. The plurality of telescopic air bags 303 are all connected to the air outlet end of the air pump 301 through an air charging pipe 302. A first solenoid valve is arranged at the air outlet end of the air pump 301.

[0026] When adjusting the height of the movable plate 6, first open the first solenoid valve and turn on the air pump 301. The air pump 301 inflates or sucks air into the telescopic air bags 303 through the air charging pipe 302, so that the telescopic air bags 303 expand or contract. Since the bottom of the movable plate 6 is connected to the telescopic air bags 303, the telescopic air bags 303 drive the movable plate 6 to rise or fall in the annular groove 5. In this way, the height of the guardrail of the bed body 1 can be adjusted.

[0027] Some babies can stand up or cling to the guardrail inside the bed body 1, but usually babies cannot stand independently and stably and are prone to falling, resulting in injuries, especially when the guardian is not beside the bed body 1. For this reason, we propose the following solutions to solve the above problems: In this embodiment, referring to Figure 1 、 Figure 2 and Figure 4 As shown, a flexible monitoring pad 2 is laid on the inner bottom of the bed body 1, and a controller 9 is arranged on the bed body 1.

[0028] Among them, the flexible monitoring pad 2 includes a flexible pad 201. A plurality of pressure sensors 202 are arranged in an array on the flexible pad 201. The pressure sensors 202 are communicatively connected to the controller. The pressure sensors are used to monitor the pressure on the upper surface of the flexible monitoring pad 2 and transmit the pressure monitoring signal to the controller 9.

[0029] Babies usually lie flat on the flexible monitoring pad 2 inside the bed body 1. The pressure distribution of the baby on the flexible pad 201 is relatively uniform. At this time, the pressure of the baby on the plurality of pressure sensors 202 under its body is not much different, and this pressure value is lower than the threshold set in the controller 9. When the baby stands up, the area of the flexible pad 201 pressed by the baby is greatly reduced, and the pressure value monitored by a single pressure sensor 202 increases, and this value is greater than the predetermined threshold in the controller 9. At this time, the controller 9 issues a warning signal to call the guardian to take care of the baby in time.

[0030] In this embodiment, referring to Figure 2 As shown, the flexible pad 201 is composed of a plurality of air bags 203. The plurality of air bags 203 together form a flexible plane, making the flexible monitoring pad 2 softer and more suitable for babies to use. And the positions of the plurality of pressure sensors 202 correspond to those of the air bags 203 one by one.

[0031] A vibration component 4 is arranged inside the bed body 1. The vibration component 4 is connected to the airbag 203 and is used to inflate or deflate the airbag 203. In the normal use mode, the guardian can turn on the vibration component 4, and the vibration component 4 drives the airbag 203 to vibrate, thereby massaging the baby on the flexible monitoring pad 2.

[0032] In this embodiment, the vibration component 4 includes a circulation chamber 401 opened inside the bed body 1. Each airbag 203 is communicated with the circulation chamber 401 through a communicating pipe 402.

[0033] The other air outlet end of the air pump 301 is connected to the circulation chamber 401 through a conduit. A second electromagnetic valve is arranged on the conduit. When starting the vibration component 4, the second electromagnetic valve is opened, and the air pump 301 drives the gas to enter the airbag 203 through the circulation chamber 401 to inflate and inhale the airbag 203. This is carried out periodically, so that the airbag 203 expands and contracts reciprocally, so as to achieve the purpose of the vibration of the flexible monitoring pad 2.

[0034] In this embodiment, a player 10 and a warning device are respectively arranged on the inner side of the bed body 1. The player 10 and the warning device are both communicatively connected to the controller 9. According to the above monitoring mechanism, when the controller 9 monitors that the baby has dangerous actions such as standing or climbing on the guardrail, the controller 9 starts the warning device to send out a warning signal, and the player 10 plays audio such as children's songs to attract the baby, so that the baby lies down again in the bed body 1.

[0035] Furthermore, in the normal environment usually, the player 10 can also be freely used for functions such as teaching assistant.

[0036] In this embodiment, referring to Figure 3 and Figure 5 as shown, the adjusting component 7 includes a horizontal groove 701 opened on the lower side of the first sub-bed body 101. A threaded rod 703 is inserted into the horizontal groove 701.

[0037] A threaded sleeve 702 facing the horizontal groove 701 is inserted on the lower side of the second sub-bed body 102. One end of the threaded rod 703 is threadedly connected to the threaded sleeve 702, and the other end of the threaded rod 703 extends outside the first sub-bed body 101 and is connected with a handle.

[0038] A guiding component 8 is further arranged between the first sub-bed body 101 and the second sub-bed body 102.

[0039] At least two adjusting components 7 are arranged on the bed body 1. When adjusting the length of the bed body 1, by driving the threaded rod 703 to rotate forward or backward, the threaded rod 703 cooperates with the threaded sleeve 702 to drive the second sub-bed body 102 to move away from or close to the first sub-bed body 101, so as to achieve the purpose of adjusting the length of the bed body 1.

[0040] In this embodiment, with reference to Figure 5 and Figure 6 As shown, the guiding assembly 8 includes a first guiding rod 801 connected to the side of the second sub-bed body 102. A first guiding groove 802 is formed in the first sub-bed body 101, and one end of the first guiding rod 801 away from the second sub-bed body 102 is slidably inserted into the first guiding groove 802. Through the guiding cooperation between the first guiding rod 801 and the first guiding groove 802, on the one hand, the connection stability between the first sub-bed body 101 and the second sub-bed body 102 can be improved, and on the other hand, the accuracy of the adjustment of the length direction of the bed body 1 by the adjusting assembly 7 can be ensured.

[0041] The movable plate 6 includes a first plate body 601 and a second plate body 602. A second guiding groove 804 is formed in the side of the first plate body 601, and a second guiding rod 803 is connected to the second plate body 602. One end of the second guiding rod 803 away from the second plate body 602 is slidably inserted into the second guiding groove 804. Through the cooperation between the second guiding rod 803 and the second guiding groove 804, when the bed body 1 is adjusted in the length direction, the movable plate 6 can always play the role of a guardrail without breakage or holes.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
