[0035] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] The present invention provides a multifunctional infant care bed, referring to Figures 1 to 11 As shown, the multifunctional infant care bed includes an auxiliary bed body device 1 and a main bed body device 2.

[0038] A receiving groove 121 is formed on the top of the auxiliary bed body device 1 , and the receiving groove 121 is adapted to the main bed body device 2 . An opening 122 is formed on the side wall of the receiving groove 121 , and the opening 122 is used for the main bed body device 2 to enter and exit the receiving groove 121 .

[0039] The main bed device 2 includes a main bed 21, a lifting and flipping mechanism 22 and a moving mechanism 23. The main bed 21 is arranged in the accommodating groove 121 and is used for infants to lie down. The lifting and flipping mechanism 22 is arranged at the bottom of the main bed 21 and is drivingly connected to the moving mechanism 23.

[0040] Under normal conditions, the moving mechanism 23 is in an initial state, in which case the moving mechanism 23 is in a lifting position and is suspended in the receiving groove 121 . At this time, the main bed body device 2 and the auxiliary bed body device 1 are fixedly connected.

[0041] When changing the trolley, the lifting and flipping mechanism 22 is started, driving the moving mechanism 23 to descend, and then the lifting and flipping mechanism 22 continues to drive the moving mechanism 23 to flip until the moving mechanism 23 abuts against the bottom of the groove. At this time, the main bed body device 2 forms a trolley, and the accompanying person pushes the trolley to make it detach from the auxiliary bed body device 1.

[0042] The main bed body device 2 of the present invention, which has a main bed body 21, a lifting and flipping mechanism 22 and a moving mechanism 23, is, on the one hand, a part of the nursing bed and is fixedly connected to the auxiliary bed body device 1 for infants to lie down. On the other hand, it can be converted into a trolley according to actual needs and used independently from the auxiliary bed body device 1. It not only has diverse functions and forms, but is also easy to use.

[0043] Embodiment 2:

[0044] Example 2 is based on Example 1:

[0045] like Figures 1 to 11 As shown, a positioning groove 123 is provided on the auxiliary bed body device 1 on the outside of the accommodating groove 121. The positioning groove 123 is a strip groove and is provided along the outside of the top notch of the accommodating groove 121. The top side outer edge of the main bed body 21 extends outward and downward to form a positioning convex eave 211. The positioning convex eave 211 matches the size of the positioning groove 123, and the positioning convex eave 211 is inserted into the positioning groove 123.

[0046] When changing the trolley, the moving mechanism 23 is driven by the lifting and flipping mechanism 22 to lower and press against the bottom of the accommodating groove 121, thereby pushing the main bed body 21 to rise. During this process, the positioning convex eaves 211 are simultaneously raised and completely separated from the positioning groove 123, at which time the trolley is formed.

[0047] In order to improve the connection stability between the main bed body device 2 and the auxiliary bed body device 1 in the initial state, opposite magnets are provided in the positioning groove 123 and on the positioning convex eaves 211, so that the positioning convex eaves 211 are firmly connected to the positioning groove 123 by magnetic adsorption.

[0048] In order to facilitate the insertion of the positioning convex eave 211 into the positioning groove 123 , a chamfer is provided at the top notch position of the positioning groove 123 .

[0049] By adopting the lifting and flipping method, the positioning groove 123 and the positioning convex eave 211 can be automatically plugged in and out, thereby realizing the connection and disconnection of the auxiliary bed body device 1 and the main bed body device 2, making the operation more convenient.

[0050] As an optional implementation, the lifting and flipping mechanism 22 includes a first driving component 221, a support frame 222 and a lifting and flipping component.

[0051] The support frame 222 is fixedly arranged at the bottom of the main bed body 21 . The first driving component 221 is an electric driving component, and the first driving component 221 is arranged on the support frame 222 .

[0052] The lifting and flipping assembly is arranged on the support frame 222, and includes a vertical guide rod 223 and a fan gear 224. The vertical guide rod 223 includes an upper sliding guide section and a lower flipping rack section that are integrally arranged. The fan gear 224 is fixedly arranged on the moving mechanism 23 and is lifted and flipped synchronously with the moving mechanism 23. The fan gear 224 is drivingly connected to the first driving assembly 221.

[0053] When the trolley is changed, the first driving assembly 221 drives the sector gear 224 to move downward along the upper sliding guide section, and the moving mechanism 23 moves synchronously therewith. When the sector gear 224 moves to the lower flip rack section, the transmission teeth of the sector gear 224 engage with the lower flip rack section and rotate along the lower flip rack section. At this time, the moving mechanism 23 flips synchronously with the sector gear 224, so that the moving mechanism 23 is pressed against the ground to form the trolley.

[0054] The vertical guide rod 223 and the sector gear 224 cooperate with each other, and the lifting and flipping action has a significant effect.

[0055] As an optional embodiment, the lifting and flipping assembly includes a turbine worm assembly and a screw sliding assembly.

[0056] The output end of the first driving assembly 221 is connected to the first driving shaft 2211 and can drive the first driving shaft 2211 to rotate.

[0057] The worm gear assembly includes a transmission worm gear 226 and a transmission worm gear 225 . The transmission worm gear 225 is fixedly sleeved on the first drive shaft 2211 and rotates synchronously with the first drive shaft 2211 . The transmission worm gear 226 is meshed with the transmission worm gear 225 .

[0058] The screw sliding assembly includes a fixed guide rail 227, a movable block 229 and a rotating screw 228. The fixed guide rail 227 is vertically arranged and adopts a frame structure. A guide groove compatible with the movable block 229 is arranged on the inner side. The rotating screw 228 is rotatably arranged on the fixed guide rail 227 through a bearing seat. The transmission turbine 226 is fixedly sleeved on the end of the rotating screw 228 and rotates synchronously with the rotating screw 228. The movable block 229 is slidably arranged in the guide groove. The movable block 229 is provided with a threaded hole through which the rotating screw 228 passes through the threaded hole and is threadedly matched with the movable block 229 through the threaded hole. The moving mechanism 23 is rotatably connected to the movable block 229.

[0059] When changing the trolley, the first drive assembly 221 drives the first drive shaft 2211 to rotate, and the transmission worm 225 rotates synchronously therewith, and the transmission turbine 226 and the rotating screw 228 rotate. At this time, under the limiting guiding action of the fixed guide rail 227, the moving block 229 moves downward along the guide groove, and the moving mechanism 23 moves downward synchronously. At the same time, the fan gear 224 moves downward along the upper sliding guide section until the fan gear 224 moves to the lower flip rack section, and the moving mechanism 23 flips relative to the moving block 229 to contact the ground.

[0060] The worm gear assembly and the screw sliding assembly cooperate with each other. On the one hand, they can effectively convert the rotational motion of the first drive assembly 221 into the movement motion of the moving block 229. On the other hand, both of them have a self-locking function, so that the moving mechanism 23 is stable whether it is in the initial state or the lifting and flipping state.

[0061] As an optional implementation, the moving mechanism 23 includes a moving wheel assembly, and the sector gear 224 is fixedly disposed on the moving wheel assembly, and the moving wheel assembly moves synchronously with the sector gear 224 .

[0062] The moving wheel assembly includes a wheel frame and a moving wheel rotatably arranged on the wheel frame. The wheel frame is provided with a mounting shaft, and the end of the mounting shaft is rotatably connected to the moving block 229 through a bearing. The sector gear 224 is fixedly sleeved on the mounting shaft.

[0063] As an optional implementation, the first driving assembly 221 includes an electric power assembly and a belt transmission assembly, and the electric power assembly is drivingly connected to two parallel first driving shafts 2211 through the belt transmission assembly.

[0064] The number of the moving wheel assemblies and the lifting and flipping assemblies are both set to two, and the two moving wheel assemblies are respectively a front moving wheel assembly 231 and a rear moving wheel assembly 232 .

[0065] The fan gears 224 of the two lifting and flipping assemblies are respectively fixedly mounted on the front mounting shaft of the front moving wheel assembly 231 and the rear mounting shaft of the rear moving wheel assembly 232. The first driving assembly 221 can drive the front moving wheel assembly 231 and the rear moving wheel assembly 232 to synchronously lift and reversely flip through the lifting and flipping assemblies.

[0066] Specifically, the front mounting shaft of the front moving wheel assembly 231 and the rear mounting shaft of the rear moving wheel assembly 232 are coaxially arranged and connected by a coupling. The front mounting shaft and the rear mounting shaft can rotate independently. The front moving wheel assembly 231 adopts a universal wheel for steering, and the rear moving wheel assembly 232 adopts a large-diameter moving wheel for improved passability. The two lifting and flipping assemblies are symmetrically distributed around the center, so that the synchronous reverse flipping action of the front moving wheel assembly 231 and the rear moving wheel assembly 232 can be effectively realized.

[0071] During actual use, the accompanying personnel activates the swing driving mechanism 13 according to the needs, and the swing driving mechanism 13 drives the swing bed body 12 to swing back and forth, thereby forming a cradle.

[0072] As an optional embodiment, an arc-shaped guide rail 112 is provided in the installation chamber 111; a sliding block 125 is fixedly provided at the bottom of the rocking bed body 12, and the sliding block 125 is arranged in an arc shape, which matches the size of the arc-shaped guide rail 112; the rocking bed body 12 is movably arranged in the installation chamber 111, and the sliding block 125 is movably arranged in the arc-shaped guide rail 112.

[0073] Furthermore, rolling elements are evenly arranged in the arc-shaped guide rail 112 , and the sliding block 125 rolls with the rolling elements, which can effectively improve the smoothness of the swinging process.

[0074] In order to further improve the stability of the swinging process, the number of the arc-shaped guide rails 112 and the number of the sliding blocks 125 are both set to be multiple.

[0075] In order not to affect the swinging movement of the rocking bed body 12, there is a clearance gap between its side wall and the cavity wall of the installation chamber 111. An elastic dust cover 14 is provided at the top of the clearance gap to seal the top. The elastic dust cover 14 is elastic and adaptively deforms as the rocking bed body 12 swings. Optionally, the elastic dust cover 14 adopts an accordion cover.

[0076] As an optional implementation, the swing drive mechanism 13 includes a second drive assembly 131 , a horizontal crank 132 , a second drive shaft 133 , a swing arm 134 and a transmission sleeve 135 .

[0078] When the cradle function is started, the second drive assembly 131 is started, driving the horizontal crank 132 to rotate, and the rod body 1351 is lifted and lowered reciprocatingly along the vertical guide hole. At the same time, the sleeve 1352 moves back and forth along the horizontal guide rod 1341, thereby driving the swing arm 134 to swing back and forth, and the second drive shaft 133 and the rocking bed body 12 swing synchronously, and the cradle effect is significant.

[0079] As an optional implementation, the swing drive mechanism 13 further includes a brake mechanism, which includes a brake pad encircling the second drive shaft 133 and an electric cylinder connected to the brake pad.

[0080] When the cradle function is turned off, the electric cylinder drives the brake pad to hold the second drive shaft 133 tightly, thereby locking its position to prevent it from rotating.

[0081] Furthermore, the swing drive mechanism 13 also includes a position detection device. Optionally, the position detection device uses a photoelectric sensor, including a sensing block and a sensor. The sensing block is fixedly set on the sliding block 125 and swings synchronously with the swing bed 12. The sensor is set on the arc guide rail 112. By sensing the position of the sensing block, the swing angle of the swing bed 12 is sensed. It cooperates with the braking mechanism to lock the swing bed 12 to a specified swing angle.
