Description

Technical Field

[0001] The invention relates to a children's bed, in particular to a children's bed with an anti-falling structure. Background Art

[0002] When children sleep alone, what adults worry about most is that the children will fall off the bed, because falling off the bed can easily cause fractures, brain damage or other injuries, and parents cannot always watch over their children while they sleep, so adding anti-fall structures to children's beds has become popular.

[0003] The anti-fall structure of the existing children's bed is usually simply to add guardrails on both sides of the bed body, but this kind of guardrail has a disadvantage. If a long-distance guardrail is used, it will affect the children's getting up at night and getting out of bed, and even trip the children and cause more serious injuries. If a short-distance guardrail is used, the protection ability will be reduced, and the children are likely to roll off the bed and fall to the ground. Therefore, how to form a long-distance guardrail around the bed body for comprehensive protection when the child is sleeping, and fold the guardrail when the child gets up at night to facilitate the children to get in and out of bed is a difficult problem that we urgently need to solve.

[0004] Therefore, those skilled in the art provide a children's bed with an anti-falling structure to solve the problems raised in the above background technology. Summary of the invention

[0011] As a further solution of the present invention: a silicone pad is embedded on a side of the vertical side plate away from the bed body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The retractable side anti-fall assembly provided in the present application can form a long-distance guardrail around the bed to provide comprehensive protection when the child is sleeping, and the guardrail can be folded up when the child gets up at night to facilitate the child to get in and out of bed.

[0019] 2. The retractable side fall prevention assembly of the present application will widen the width of the bed when extended to form a guardrail. Not only does it not need to occupy additional sleeping space for children, but it can also expand the space to provide children with a more spacious bed, thereby reducing the possibility of children falling.

[0020] 3. The positioning detection mechanism set up in the present application can connect the positioning block on the rotating plate with the positioning groove of the vertical side plate when the retractable side fall protection assembly is extended to form a guardrail, which not only blocks the gap between the vertical side plate and the headboard body to improve safety, but also improves the overall stability between the rotating plate and the vertical side plate.

[0021] 4. When the rotating plate of the present application is connected to the vertical side plate, the positioning block is inserted into the positioning groove to trigger the pressure sensor. After receiving the signal from the pressure sensor, the infrared sensor emits infrared light to hit the sensing diaphragm, thereby constructing a detection mechanism above the vertical side plate to detect whether the child has turned over the vertical side plate or placed his limbs on the vertical side plate while sleeping.

[0022] 5. The buffer component provided in the present application can take corresponding buffering measures when a child turns over the vertical side board or puts his limbs on the vertical side board while sleeping, that is, the rubber stick and the rubber plate are extended. When the child falls from the bed, the rubber stick above can buffer the child's downward trend, and the rubber plate and the shock-absorbing pad can further buffer the impact force of the child's fall, thereby reducing the degree of injury.

[0023] 6. Since the dust and stains under the bed are difficult to clean, it often brings great inconvenience to users. The rubber plate of the buffer assembly of the present application covers the ground under the bed, replacing the dust and debris that fall from the bottom of the bed. These dust and debris are also brought out when the rubber plate is extended, making it easy to clean.

[0024] 7. Since there are a large number of toys in the children's room, some toys are directly scattered around the children's bed. When the child falls from the bed and hits these toys, it may cause greater injuries. When the buffer component of the present application extends the rubber plate, the rubber plate pushes away the toys around the bed, thereby preventing the child from being injured by the toys when falling from the bed.

DETAILED DESCRIPTION

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figures 1 to 9 In an embodiment of the present invention, a child bed with an anti-fall structure includes a bed body 1, one end of the bed body 1 is fixedly connected to a bed head body 2, and the other end of the bed body 1 is fixedly connected to a bed foot body 3; retractable side anti-fall components are symmetrically provided on both sides of the bed body 1, and a buffer component is provided under the bed body 1. The present application can form a long-distance guardrail around the bed body 1 for comprehensive protection when the child is sleeping, and the guardrail can be folded when the child gets up at night to facilitate the child to get in and out of bed.

[0037] In this embodiment: the retractable side anti-fall assembly specifically includes: an inclined slot 4 opened inside the bed body 1, a first inclined plate 5 is movably connected to the position near the top of the inclined slot 4, and one end of the first inclined plate 5 extends out of the inclined slot 4 and is fixedly connected to the vertical side plate 6, a second inclined plate 7 is movably connected to the position near the bottom of the inclined slot 4, and the second inclined plate 7 contacts the first inclined plate 5, and the contact surfaces of the second inclined plate 7 and the first inclined plate 5 are both inclined surfaces and match, and a lead screw 9 is passed through and threadedly connected to the second inclined plate 7, a stepper motor 8 is embedded in the position of the lead screw 9 on the inner wall of one side of the inclined slot 4, and the output shaft of the stepper motor 8 is fixedly connected to the lead screw 9, and a positioning detection mechanism is provided on the two sides of the head of the bed 2 corresponding to the position of the vertical side plate 6, and a switch electrically connected to the stepper motor 8 is fixedly connected to one side of the top surface of the head of the bed 2. When the retractable side anti-fall assembly is extended to form a guardrail, it will widen the width of the bed body 1, not only does not need to occupy the extra sleeping space of the children, but also can expand the space to give the children a more spacious bed, thereby reducing the possibility of children falling.

[0038] In this embodiment: the first inclined plate 5 is fixedly connected with an anti-slip strip 28 on the inclined surface facing the second inclined plate 7, and an anti-slip groove 29 is provided on the inclined surface of the second inclined plate 7 at a position corresponding to the anti-slip strip 28, and the anti-slip strip 28 is movably connected inside the anti-slip groove 29. The coordinated use of the anti-slip strip 28 and the anti-slip groove 29 can not only prevent the first inclined plate 5 from being separated from the second inclined plate 7, but also limit the extension length of the first inclined plate 5, and facilitate the subsequent retraction of the first inclined plate 5.

[0039] In this embodiment: the positioning detection mechanism specifically includes: a rotating groove 11 opened on both sides of the headboard body 2, a rotating plate 12 is rotatably connected inside the rotating groove 11, and an infrared sensor 15 is embedded on the top of the rotating plate 12, and both sides of the side of the foot body 3 facing the headboard body 2 are embedded with a sensing diaphragm 34, and a double-axis motor 13 is embedded in the middle position inside the headboard body 2, and the two output shafts of the double-axis motor 13 are fixedly connected with the optical axis 14, and the optical axis 14 passes through the headboard body 2 and is fixedly connected to the corresponding rotating plate 12, a positioning block 16 is fixedly connected to the top of the side of the rotating plate 12, a positioning groove 17 matching the positioning block 16 is opened on one side of the top surface of the vertical side plate 6, and a pressure sensor 18 is fixedly connected to the bottom end surface of the positioning groove 17, and the rotating plate 12 can be rotated ninety degrees to make the positioning block 16 fit into the positioning groove 17 and contact the pressure sensor 18. The positioning detection mechanism can be connected with the positioning groove 17 of the vertical side plate 6 through the positioning block 16 on the rotating plate 12 when the retractable side fall prevention assembly is extended to form a guardrail, which not only blocks the gap between the vertical side plate 6 and the headboard body 2 to improve safety, but also improves the overall stability between the rotating plate 12 and the vertical side plate 6. When the rotating plate 12 of the present application is connected to the vertical side plate 6, the positioning block 16 is inserted into the positioning groove 17 to trigger the pressure sensor 18, and the infrared sensor 15 receives the signal from the pressure sensor 18 and operates to emit infrared light to hit the sensing diaphragm 34, thereby constructing a detection mechanism above the vertical side plate 6 to detect whether the child has turned over the vertical side plate 6 or has his limbs on the vertical side plate 6 while sleeping.

[0040] In this embodiment, a silicone pad 10 is embedded on a side of the vertical side plate 6 away from the bed body 1. The setting of the silicone pad 10 can prevent children from hitting the edge of the bed and getting injured.

[0041] In this embodiment: the buffer assembly specifically includes: rectangular grooves 19 opened on both sides of the bottom end surface of the bed body 1, the inner tops of the two rectangular grooves 19 are connected to the bidirectional threaded rods 20 for rotation, and the inner parts of the rectangular grooves 19 are movably connected to the support plates 25, the bidirectional threaded rods 20 penetrate the support plates 25 and are threadedly connected thereto, and the bottom end of the support plates 25 is fixedly connected to the rubber plate 32, and the bottom end surface of the rubber plate 32 is embedded with a plurality of evenly distributed rotatable rubber rollers 33 along its width direction, and a driving mechanism is provided between the two rectangular grooves 19 for driving the bidirectional threaded rods 20 to rotate. Through the provided buffer assembly, corresponding buffering countermeasures can be taken when the child turns over the vertical side plate 6 or puts his limbs on the vertical side plate 6 while sleeping, that is, the rubber rods 27 and the rubber plates 32 are extended, and when the child falls from the bed body 1, the rubber rods 27 above are used to buffer the downward trend of the child, and the rubber plates 32 and the shock-absorbing pads 31 are used to further buffer the impact force of the child's fall, thereby reducing the degree of injury. Since the dust and stains under the bed are difficult to clean, it often brings great inconvenience to the user. The rubber plate 32 of the buffer assembly of the present application covers the ground under the bed, replacing the dust and debris that fall from the bed. When the rubber plate 32 is extended, the dust and debris are also brought out, which is convenient for cleaning. In addition, since there are a large number of toys in the children's room, some toys are directly scattered around the children's bed. When the children fall from the bed and hit these toys, it may cause greater injuries. When the buffer assembly of the present application extends the rubber plate 32, the rubber plate 32 pushes away the toys around the bed, thereby preventing the children from hitting the toys and getting injured when falling from the bed.

[0042] In this embodiment: the driving mechanism specifically includes: a driving motor 21 fixed at the middle position of the bottom end surface of the bed body 1, a driving cavity 22 is opened above the driving motor 21, and the top output shaft of the driving motor 21 passes through the driving cavity 22 and is fixedly connected to the first bevel gear 23, the bidirectional threaded rod 20 passes through the driving cavity 22, and the outside of the bidirectional threaded rod 20 in the driving cavity 22 is fixedly connected to the second bevel gear 24, and the first bevel gear 23 is meshed with the second bevel gear 24. The driving mechanism can drive the rubber stick 27 and the rubber plate 32 to extend or retract.

[0043] In this embodiment, a plurality of telescopic holes 26 connected to the rectangular groove 19 are provided on the side of the bed body 1 along its length direction, and a rubber rod 27 is movably connected inside the telescopic hole 26, and one end of the rubber rod 27 is fixedly connected to the corresponding support plate 25. The rubber rod 27 extends to cushion the downward trend of the child when falling, and has a certain cushioning effect.

[0044] In this embodiment, a shock-absorbing pad 31 is fixedly connected to the top surface of the rubber plate 32 . The shock-absorbing pad 31 can further cushion the impact force of a child falling on the rubber plate 32 .

[0045] In this embodiment, a sound-absorbing cotton 30 is embedded above the two rectangular grooves 19. The sound-absorbing cotton 30 can absorb the noise generated when the buffer component is running to a certain extent, so as to avoid affecting the sleep of children.

[0046] The working principle of the present invention is: when in use, first, when the child lies on the bed and prepares to sleep, the switch on the headboard 2 is pressed, and the retractable side anti-falling assembly runs and stretches to form guardrails on both sides of the bed 1, specifically: the stepper motor 8 drives the lead screw 9 to rotate, and the second inclined plate 7 moves forward along the lead screw 9 at the bottom of the inclined slot 4. During the process, the second inclined plate 7 and the first inclined plate 5 produce an inclined surface effect, and the first inclined plate 5 is pushed by the second inclined plate 7 and slowly extends outward along the inclined slot 4. During the process, the vertical side plate 6 rises obliquely until the anti-slip strip 28 hits one end of the anti-slip slot 29. At this time, the vertical side plate 6 is higher than the plane where the bed 1 is located, and forms a barrier on both sides of the bed 1. Next, the positioning detection mechanism operates, specifically: the dual-axis motor 13 operates to drive the optical axis 14 to rotate ninety degrees, and then drives the rotating plate 12 to rotate out of the rotating groove 11 and rest on the first inclined plate 5. During the process, the positioning block 16 is inserted into the positioning groove 17 and triggers the pressure sensor 18. The pressure sensor 18 sends an operation signal to the infrared sensor 15. After receiving the signal from the pressure sensor 18, the infrared sensor 15 operates to emit infrared light to hit the sensing diaphragm 34, thereby constructing a detection mechanism above the vertical side plate 6 to detect whether the child has turned over the vertical side plate 6 or has placed his limbs on the vertical side plate 6 while sleeping. When a child turns over the vertical side plate 6 or puts his limbs on the vertical side plate 6 while sleeping, the limbs block the infrared light emitted by the infrared sensor 15, and the infrared sensor 15 sends an operation signal to the driving mechanism of the buffer assembly. After receiving the signal, the driving mechanism extends the rubber stick 27 and the rubber plate 32. When the child falls from the bed body 1, the rubber stick 27 above cushions the child's downward trend, and the rubber plate 32 and the shock-absorbing pad 31 further cushion the impact of the child's fall, thereby reducing the degree of injury. The specific process is: the driving motor 21 runs to drive the first bevel gear 23 to rotate. Since the first bevel gear 23 is meshed with the second bevel gear 24, the second bevel gear 24 rotates synchronously with the first bevel gear 23, thereby driving the bidirectional threaded rod 20 to rotate. The two support plates 25 on the bidirectional threaded rod 20 move away from each other along the corresponding rectangular grooves 19. During the process, the rubber stick 27 extends out of the bed body 1 along the telescopic hole 26, and the bottom of the support plate 25 pushes the rubber plate 32 to extend from under the bed. During the process, the rubber roller 33 rolls to reduce the friction resistance between the rubber plate 32 and the ground. Since the dust and stains under the bed are difficult to clean, it often brings great inconvenience to the user. The rubber plate 32 of the buffer assembly of the present application covers the ground under the bed, replacing the dust and debris that fall from the bed. When the rubber plate 32 is extended, the dust and debris are also brought out, which is convenient for cleaning. In addition, since there are a large number of toys in the children's room, some toys are directly scattered around the children's bed. When the children fall from the bed and hit these toys, it may cause greater injuries. When the buffer assembly of the present application extends the rubber plate 32, the rubber plate 32 pushes away the toys around the bed, thereby preventing the children from hitting the toys and getting injured when falling from the bed.When the child wakes up at night and wants to get out of bed, he can press the switch of the bed head body 2 again. At this time, the dual-axis motor 13 first runs to retract the rotating plate 12 into the rotating groove 11, and then the stepper motor 8 runs to drive the lead screw 9 to reverse, and the second inclined plate 7 slowly retreats to the original position. The first inclined plate 5 is retracted into the inclined groove 4 under the connection between the anti-slip strip 28 and the anti-slip groove 29, so that the top of the vertical side plate 6 drops to be flush with the top surface of the bed body 1, making it convenient for children to get in and out of bed. It should be noted that the stepper motor 8, the dual-axis motor 13, the infrared sensor 15, the pressure sensor 18, the drive motor 21 and the switch are all operated according to the pre-set program.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
