Description

Technical Field

[0001] This invention relates to the field of baby crib technology, specifically a foldable portable smart baby crib. Background Technology

[0002] As a special piece of furniture for infants and toddlers' sleep and activities, cribs are important childcare products that ensure safe sleep for infants and toddlers and reduce the burden of care. Most cribs on the market are made of solid wood or environmentally friendly and safe materials. The overall structure is stable and there are protective rails on all four sides. The size of the crib, the spacing of the rails and the height all meet the safety standards for infants and toddlers, which can effectively avoid the risks of bumps, trapping and falling.

[0003] Prior art 1 (Chinese patent publication number CN215820370U, publication date 2022-02-15) discloses a baby crib, including a support assembly and a crib body, and further including an adjustment structure. The adjustment structure is sleeved on the support assembly and connected to the crib body. The adjustment structure can slide back and forth on the support assembly. The crib body slides back and forth on the support assembly via the adjustment structure. A reset device is also provided on the support assembly. When the crib body moves forward or backward on the support assembly via the adjustment structure, the reset device resets the crib body. The crib body moves back and forth on the support assembly to adjust the position of the crib body, so as to facilitate the user to adjust the position of the crib body according to the needs of use, making it convenient for the user to use. The reset device can be used to reset the position of the crib body. There is also prior art 2 (publication number CN21...). (Chinese Patent 0696864U, published on 2020-06-09) A crib includes a crib frame and at least two guardrail assemblies. At least one guardrail assembly is connected to each opposite side of the crib frame. The crib also includes an adjustment component, with the adjustment component connected to both ends of each guardrail assembly. The adjustment component engages with the crib frame. When the adjustment component is pushed, it releases its locking relationship with the crib frame, allowing the adjustment component and the guardrail assemblies to slide up and down along the crib frame. The adjustment component connects the guardrail assemblies to the crib frame, and a simple push releases the locking relationship, making height adjustment of the adjustment component and guardrail assemblies easier and faster, facilitating parental care and interaction with the baby, and providing a better user experience.

[0004] While existing technologies have achieved bed position adjustment through structural adjustment, their overall structure is complex, occupies a large space, and is not convenient to use and transport. Furthermore, the stability of the bed after it is unfolded is poor, and long-term use may lead to structural deformation, thereby affecting the safety of use.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing foldable portable smart cribs. Therefore, we proposed that foldable portable smart cribs can effectively solve these problems. Summary of the Invention

[0006] The purpose of this invention is to provide a foldable portable smart baby bed to solve the problems mentioned in the background art. Currently, the bed position can be adjusted by adjusting the structure, but the overall structure is complex, occupies a lot of space, is not convenient to use and move, and the stability after the bed is unfolded is poor. Long-term use may lead to structural deformation, thereby affecting the safety of use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a foldable portable smart baby bed, comprising a support assembly, a movement bed board assembly, a fixing frame assembly, and a leg assembly. The support assembly includes a frame connector, a frame tube at the side end of the frame connector, a folding hinge connected below the frame tube, a leg tube connector connected below the folding hinge, and a leg tube body connected below the leg tube connector. The movement bed board assembly includes a bed board body, a bed board support tube at the bottom periphery of the bed board body, and the bed board body is symmetrically arranged. The fixing frame assembly includes bed board slide rails, four sets of which are provided. The bed board slide rails are connected to the leg tube bodies by rivets, and the leg assembly is inserted into the leg tube bodies.

[0008] Preferably, a lower frame baffle is provided at the lower part of the frame connector, the lower frame body is connected to the inner side of the lower frame baffle, a circuit board mounting seat is fixed on the frame connector, and a control circuit board is installed on the circuit board mounting seat.

[0009] Preferably, the bed board support tube is connected to a folding joint in the middle, and a fixing pin is inserted inside the folding joint.

[0010] Preferably, the bed board support tube is provided with rubber-coated bearings on both sides, and bearing washers are provided on the inner side of the rubber-coated bearings. There are eight sets of rubber-coated bearings and bearing washers. The rubber-coated bearings and bearing washers are fixed to the bed board support tube by rivets.

[0011] Preferably, a drive fixing bracket is provided at the bottom of one side of the bed board support tube, and a drive assembly is installed on the drive fixing bracket.

[0012] Preferably, the drive assembly includes a motor and a gearbox assembly mounted on a drive mounting bracket. The motor and gearbox assembly are connected by a drive wheel and a drive belt. A photoelectric sensor is also mounted on the drive mounting bracket. The photoelectric sensor is used to control the crankshaft to return to the zero position. A stabilizing connecting pipe is installed at the bottom of the other side of the bed board slide rail. The stabilizing connecting pipe is located at the bottom of the bed board support pipe.

[0013] Preferably, the exercise bed board assembly and the fixing frame assembly are both connected to the inside of the support assembly and can be moved and closed in conjunction.

[0014] Preferably, the drive fixing bracket, the stabilizing connecting pipe and the bed board slide rail are connected to form an U-shaped structure. The output end of the gearbox assembly is connected to the crankshaft drive. The crankshaft is rotatably mounted on the bottom of the bed board body. A bearing is mounted at the end of the crankshaft. The bearing slides inside the rotating sleeve. The rotating sleeve is fixed to the bottom of the bed board body. The motor drives the crankshaft to rotate through the gearbox assembly. The bearing forms a transmission engagement with the rotating sleeve, thereby driving the bed board body to perform linear reciprocating motion along the bed board slide rail.

[0015] Preferably, the lower frame body can be folded inward around the lower frame baffle. When folded, the exercise bed board assembly, the leg assembly and the support assembly fold synchronously, and stand with the leg assembly as the fulcrum.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The foldable portable smart baby bed uses a frame connector as its top core, firmly connecting the frame tubes to form an upper protective frame. The frame tubes are connected to the leg tube connectors via hinges, and the lower fixed leg tube bodies form vertical support, effectively preventing the bed from wobbling or tipping over, and significantly improving the overall structural rigidity of the bed. The specific details are as follows: The support assembly uses the frame connector as the top core, which firmly connects the frame tube to form the upper protective frame. The lower frame baffle at the bottom of the frame connector cooperates with the lower frame body to provide limiting protection for the bottom of the bed, greatly improving the overall structural rigidity of the bed and ensuring the safety of infants and young children during use.

[0017] The exercise bed board assembly serves as the main support for infants. It features a symmetrically arranged bed board body with the bottom outer perimeter supported by bed board support tubes. This ensures even force distribution on the bed board, prevents localized dents, and enhances the comfort and safety of infants while lying down, thus meeting their daily rest needs.

[0018] A dedicated circuit board mounting bracket is fixed on the frame connector, which can stably install the control circuit board, providing reliable circuit control and power supply for the electric drive system, realizing intelligent start-stop and mode adjustment, convenient operation and stable operation, improving the ease of operation and reducing the difficulty of use.

[0019] The fixed frame assembly provides stable drive and guidance for the electric rocking motion. The bed board slide rail, stable connecting pipe and drive fixed bracket are connected to form a high-strength U-shaped structure with strong resistance to deformation. It is not easy to loosen after long-term use. The crankshaft drives the bed board body to make smooth linear reciprocating motion along the slide rail, realizing the electric automatic rocking function and reducing the burden of caregivers.

[0020] When storing, the lower frame body can be flipped inward around the lower frame baffle to pre-fold it. The operation is simple and effortless. Pulling the folding handle will drive the exercise bed board assembly, fixing frame assembly, support leg assembly and bracket assembly to fold in a synchronized manner. The folding connection hinge drives the frame tube to fold inward, greatly reducing the overall volume and saving storage space. Attached Figure Description

[0025] In this embodiment, the crankshaft drives the bed board body 201 to make a smooth linear reciprocating motion along the bed board slide rail 301, realizing the electric automatic rocking function without manual pushing, freeing up parents' hands. Specifically, as follows... Figures 3-8As shown, a drive fixing bracket 302 is provided at the bottom of one side of the bed board support tube 202. A drive assembly is installed on the drive fixing bracket 302. The drive assembly includes a motor 303 and a gearbox assembly 304 mounted on the drive fixing bracket 302. The motor 303 and the gearbox assembly 304 are connected by a transmission wheel 306 and a transmission belt 305. A photoelectric sensor 307 is also installed on the drive fixing bracket 302. The photoelectric sensor 307 is used to control the crankshaft to return to the zero position. A stabilizing connecting tube 308 is installed at the bottom of the other side of the bed board slide rail 301. The stabilizing connecting tube 308 is located at the bottom of the bed board support tube 202. The moving bed board assembly 2 and the fixing frame assembly 3 are both connected to the support. The inner side of the frame assembly 1 can be linked and retracted. The drive fixed bracket 302, the stable connecting pipe 308 and the bed board slide rail 301 are connected to form an orifice structure. The output end of the gearbox assembly 304 is connected to the crankshaft drive. The crankshaft is mounted on the bottom of the bed board body 201. The end of the crankshaft is equipped with a bearing, which slides inside the rotating sleeve. The rotating sleeve is fixed to the bottom of the bed board body 201. The motor 303 drives the crankshaft to rotate through the gearbox assembly 304. The bearing forms a transmission engagement with the rotating sleeve, thereby driving the bed board body 201 to perform linear reciprocating motion along the bed board slide rail 301. The fixed frame assembly 3 provides drive and guidance for the electric rocking motion. The bed board slide rail 301 is movable to the support tube body 107 through rivets 207. The connection provides linear motion guidance for the motion bed board assembly 2. The bed board slide rail 301, the stable connecting pipe 308, and the drive fixing bracket 302 are connected to form a U-shaped structure, which has high structural strength and strong resistance to deformation, and is not easy to loosen or deform after long-term use. The drive assembly is installed on the drive fixing bracket 302. The motor 303 and the gearbox assembly 304 are fixedly installed on the drive fixing bracket 302. The motor 303 and the gearbox assembly 304 are connected by two sets of large and small transmission pulleys 306 and a transmission belt 305 to form a belt drive. The power output by the motor 303 is transmitted to the gearbox assembly 304 through the transmission pulleys 306 and the transmission belt 305. After reduction and torque amplification adjustment, a stable torque power is output. The output end of component 304 is connected to the crankshaft, which is movably mounted on the bottom of the bed board body 201. The power drives the crankshaft to rotate continuously, and in conjunction with the linkage structure of the bearing and the rotating sleeve, it synchronously drives the bed board body 201 to make a smooth linear reciprocating motion along the bed board slide rail 301, thereby realizing the electric automatic rocking function of the device. No manual pushing is required, freeing up parents' hands. A photoelectric sensor 307 is also installed on the drive fixing bracket 302, which can accurately detect the position of the crankshaft. When the stop button is pressed, the photoelectric sensor 307 controls the crankshaft to automatically return to the zero position, so that the bed board stops accurately. At the same time, it makes the folding joint 203 and each rotating shaft aligned, providing accurate positioning conditions for subsequent folding operations and avoiding jamming during folding. Example

[0026] In this embodiment, the retractable hinge 103 synchronously drives the frame tube 102 to retract inward. The support assembly 1, the exercise bed board assembly 2, the fixing frame assembly 3, and the support leg assembly 4 achieve synchronous and coordinated retraction of multiple components, significantly reducing the overall volume and saving storage space. Specifically, as shown below... Figure 3 and Figures 9-12 As shown, the following is disclosed: the lower frame body 106 can be folded inward around the lower frame baffle 105. When folded, the motion bed board assembly 2, the support leg assembly 4, and the support frame assembly 1 fold synchronously, and stand upright with the support leg assembly 4 as the fulcrum. When storage is required, the lower frame body 106 can be flipped and folded inward around the lower frame baffle 105 to complete the pre-folding of the lower frame. The operation is simple and effortless. Then, by pulling the folding handle, the motion bed board assembly 2 folds inward around the folding joint 203, which at the same time drives the bed board slide rail 301, the drive fixing bracket 302, and other fixing frame assemblies 3. Simultaneously folding downwards, the fixed frame assembly 3 further links the support leg assembly 4 and the support tube body 107 to fold around the corresponding fulcrum. The folding connection hinge 103 simultaneously drives the frame tube 102 to fold inwards. The support assembly 1, the exercise bed board assembly 2, the fixed frame assembly 3, and the support leg assembly 4 achieve simultaneous linkage folding of multiple components. The entire process is smooth and without jamming. After folding, the bed stands upright with the support leg assembly 4 as the fulcrum. The overall volume is greatly reduced, significantly saving storage space and making it easy to store, move, and carry when going out, taking into account both indoor daily use and outdoor portable use needs.
