Description

Technical Field

[0001] This utility model relates to the field of soft bed technology, specifically to a multifunctional mother-and-child soft bed. Background Technology

[0002] In modern home life, with the diversified needs of living space and the continuous changes in family structure, higher requirements are placed on the functionality and space utilization of beds. A bunk bed is a piece of furniture that has a mother bed and a daughter bed. Bunk beds can effectively increase sleeping space and are especially suitable for children's rooms or small apartments.

[0003] In existing technology, the child bed is usually hidden under the mother bed. When needed, the child bed is pulled out from under the mother bed. However, there is generally a height difference between the child bed and the mother bed. When children use the bed, due to their limited cognitive abilities, they are prone to falling because they cannot accurately judge and adapt to this height change, resulting in abrasions, sprains, or even more serious fractures. Furthermore, parents need to frequently look down to check on the child's position when supervising the child. Therefore, those skilled in the art provide a multifunctional soft bed with a child to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional soft bed with a mother-daughter design to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a multifunctional soft bed with a mother bed frame, a headboard fixedly connected to the outer wall of the mother bed frame, a keel fixedly connected inside the mother bed frame, a first mattress placed on the upper top of the keel on one side of the headboard, a daughter bed mechanism slidably placed inside the mother bed frame, a support mechanism for support provided at the lower bottom of the daughter bed mechanism, and two sets of lifting mechanisms for lifting the daughter bed mechanism provided between the support mechanism and the daughter bed mechanism.

[0006] Preferably, the sub-bed mechanism includes a sub-bed frame, a first support plate is fixedly connected inside the sub-bed frame, a second support plate is rotatably sleeved inside the sub-bed frame on one side of the first support plate, and four sets of guide rails are symmetrically placed inside the sub-bed frame on one side of the first and second support plates, with two guide rails in each set.

[0007] Preferably, a collection box for storing items is slidably fitted onto the outer wall of each pair of guide rails, and a total of four collection boxes are provided. Multiple positioning holes are evenly opened at the top top of the sub-bed frame, and multiple protective rails for protection are inserted into the top top of the sub-bed frame corresponding to the positioning holes. The protective rails can be detached and placed inside the collection box.

[0008] Preferably, the second support plate has insertion holes on both sides of its outer wall, and the sub-bed frame has positioning pins inserted into the corresponding insertion holes on both sides of its outer wall. The ends of the positioning pins are inserted into the insertion holes. The first support plate and the second support plate have a second pad placed on their upper top ends. The support mechanism includes a guide frame, and L-shaped brackets are symmetrically fixed to both sides of the outer wall of the guide frame. Each L-shaped bracket has an inner bearing embedded on the side closest to each other.

[0009] Preferably, each lifting mechanism includes a lifting bracket fixedly connected to the top of the guide frame. Two fixed brackets are symmetrically fixedly connected to the upper top edge of the lifting bracket. A guide rod is fixedly connected inside the two fixed brackets. Two bearing brackets are symmetrically fixedly connected to the upper top of the lifting bracket on one side of the two fixed brackets.

[0010] Preferably: The two bearing frames are internally connected to threaded screws via bearings. A sliding frame is provided on the outer wall of the threaded screw and the guide rod. The sliding frame is slidably sleeved on the outer wall of the fixed frame. The sliding frame is slidably sleeved with the guide rod and threadedly sleeved with the threaded screw. A rotating wheel is fixedly connected to the side of each of the two threaded screws that is close to each other. A splined shaft is fixedly connected to the edge of the side of each of the two rotating wheels that is close to each other. A shrinking sleeve is provided between the two splined shafts. Splined sleeves are slidably sleeved at both ends of the shrinking sleeve, and the splined sleeves are slidably sleeved with the splined shaft.

[0011] Preferably, two second connecting frames are rotatably sleeved between every two inner bearings via a rotating shaft. First connecting frames are rotatably sleeved on both sides of the outer wall of the sliding frame. The end of the second connecting frame away from the inner bearing is rotatably sleeved between the two first connecting frames via a rotating shaft. Two fixed brackets are symmetrically fixedly connected to the lower bottom ends of the first support plate and the second support plate. The ends of the two first connecting frames away from the sliding frame are rotatably sleeved between every two fixed brackets via a rotating shaft. After the sub-bed frame is lifted, it is flush with the top of the mother bed frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a support mechanism and a lifting mechanism. The sub-bed mechanism slides and retracts to the bottom of the mother bed frame via the support mechanism. When needed, the sub-bed mechanism can slide out from inside the mother bed frame. To align the tops of the mother bed frame and the sub-bed frame, the retraction sleeve, spline sleeve, and spline shaft are rotated. The two spline shafts synchronously drive the rotating wheel and threaded screw to rotate, while the two threaded screws drive the sliding frame to move linearly. When the sliding frame moves linearly, it drives the first connecting frame to move linearly and presses against the fixed bracket, causing the first and second connecting frames to move in an arc shape. The fixed bracket is subjected to the force of the first connecting frame. After being squeezed, the second support plate and the first support plate will be pushed up. This method can realize the lifting and lowering movement of the sub-bed frame, so that the tops of the mother bed frame and the sub-bed frame are level. During use, the user can retract one of the spline sleeves to let the spline sleeve enter the interior of the retracting sleeve, then pull the two positioning pins out of the interior of the second support plate, and then rotate the spline shaft located below the second support plate to drive the threaded screw to rotate. This operation is the same as the above, except that the end of the second support plate will move in an arc shape, so that the back of the second support plate will be tilted, so that the user can use it more comfortably.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-5 As shown, this utility model provides a technical solution: a multifunctional soft bed with a mother bed frame 1, a headboard 2 fixedly connected to the outer wall of the mother bed frame 1, a keel 6 fixedly connected inside the mother bed frame 1, a first mattress 3 placed on the upper top of the keel 6 on one side of the headboard 2, a daughter bed mechanism 4 slidably placed inside the mother bed frame 1, a support mechanism 7 for support is provided at the lower bottom of the daughter bed mechanism 4, and two sets of lifting mechanisms 8 for lifting the daughter bed mechanism 4 are provided between the support mechanism 7 and the daughter bed mechanism 4.

[0017] It should be noted that the headboard 2 is fixed to the outer wall of the mother bed frame 1, which not only provides users with comfortable support but also enhances the overall aesthetics. The internal keel 6 provides stable support, and the first mattress 3 is placed on the top of the keel 6 and located on one side of the headboard, providing softness and comfort for a good sleep experience. The child bed mechanism 4 is slidably placed inside the mother bed frame 1 and can be easily pulled out or stored when needed, flexibly changing the use of the space to meet different needs. The support mechanism 7 is located at the bottom of the child bed mechanism 4, providing stable support for the child bed and ensuring safety. Two sets of lifting mechanisms 8 are symmetrically arranged between the support mechanism 7 and the child bed mechanism 4, which can precisely lift the child bed mechanism 4, allowing users to adjust the height of the child bed according to their own needs. Whether used as an independent small bed or used in conjunction with the mother bed, a suitable height can be found, improving the comfort of use.

[0018] As one implementation method in this embodiment, please refer to Figure 1 -- Figure 4As shown, the sub-bed mechanism 4 includes a sub-bed frame 41. A first support plate 42 is fixedly connected inside the sub-bed frame 41. A second support plate 43 is rotatably sleeved inside the sub-bed frame 41 on one side of the first support plate 42. Four sets of guide rails 47 are symmetrically placed inside the sub-bed frame 41 on one side of the first support plate 42 and the second support plate 43. Each set of guide rails 47 has two guide rails. A collection box 45 for storing items is slidably sleeved on the outer wall of every two guide rails 47. A total of four collection boxes 45 are provided. Multiple positioning holes 46 are evenly opened at the top of the sub-bed frame 41. The top of the sub-bed frame 41 corresponds to the positioning holes. Multiple protective railings 44 are inserted at position 46 for protection. The protective railings 44 can be detached and placed inside the collection box 45. Insertion holes 48 are opened on both ends of the outer wall of the second support plate 43. Positioning pins 49 are inserted on both sides of the outer wall of the sub-bed frame 41 at the positions corresponding to the insertion holes 48. The ends of the positioning pins 49 are inserted into the inside of the insertion holes 48. The second pad 5 is placed on the upper top of the first support plate 42 and the second support plate 43. The support mechanism 7 includes a guide frame 71. L-shaped brackets 72 are symmetrically fixedly connected on both sides of the outer wall of the guide frame 71. An inner bearing 73 is embedded on the side of each L-shaped bracket 72 that is close to each other.

[0019] It should be noted that the sub-bed frame 41 is equipped with a first support plate 42 and a rotatable second support plate 43, which can flexibly adjust the support structure to meet different usage needs. Four sets of guide rails 47 are symmetrically distributed, with each pair working in conjunction with a collection box 45, for a total of four collection boxes 45 for classified storage of items, making storage more organized. Multiple positioning holes 46 at the top of the sub-bed frame 41 are adapted to the detachable guardrail 44. After the guardrail 44 is removed, it can be placed into the collection box 45, saving space and facilitating storage. The insertion holes 48 at both ends of the second support plate 43 cooperate with the positioning pins 49 on both sides of the sub-bed frame 41 to quickly fix the second support plate 43, which is easy to operate. The L-shaped brackets 72 on both sides of the guide frame 71 of the support mechanism 7 are embedded with internal bearings 73, which can stably support the sub-bed mechanism 4, reduce friction, and make the sub-bed move more smoothly.

[0020] As one implementation method in this embodiment, please refer to Figure 4 and Figure 5As shown, each lifting mechanism 8 includes a lifting bracket 81 fixedly connected to the top of the guide frame 71. Two fixed brackets 82 are symmetrically fixedly connected to the upper top edge of the lifting bracket 81. A guide rod 83 is fixedly connected inside the two fixed brackets 82. Two bearing brackets 841 are symmetrically fixedly connected to the upper top of the lifting bracket 81 on one side of the two fixed brackets 82. Threaded screws 84 are rotatably sleeved inside the two bearing brackets 841 through bearings. The threaded screws 84 are set with the outer wall of the guide rod 83. There is a sliding frame 85, which is slidably sleeved on the outer wall of the fixed frame 82. The sliding frame 85 is slidably sleeved with the guide rod 83 and threadedly sleeved with the threaded screw 84. A rotating wheel 86 is fixedly connected to the side of the two threaded screws 84 that are close to each other. A spline shaft 87 is fixedly connected to the edge of the side of the two rotating wheels 86 that are close to each other. A shrink sleeve 9 is provided between the two spline shafts 87. Spline sleeves 10 are slidably sleeved at both ends of the shrink sleeve 9. Spline sleeves 10 are slidably sleeved with spline shafts 87.

[0021] It should be noted that the lifting bracket 81 is fixed to the top of the guide frame 71, providing stable support for the entire mechanism. Two fixed brackets 82 are symmetrically fixed to the top edge of the lifting bracket 81, and together with the guide rod 83, they provide precise guidance for the sliding frame 85, ensuring smooth sliding. The threaded screws 84 fixed to the two bearing brackets 841 work together with the guide rod 83 on the sliding frame 85. Through threaded transmission, the sliding frame 85 can move precisely along the guide rod 83, realizing the lifting and lowering adjustment of the sub-bed. Two rotating wheels 86 are fixed on the threaded screws 84 on one side close to each other. Rotating the rotating wheels 86 can drive the threaded screws 84 to rotate, which is convenient to operate. The spline shaft 87 and the spline sleeve 10 are cleverly designed. The two spline sleeves 10 inside the shrink sleeve 9 slide and engage with the spline shaft 87, which can quickly connect or separate the two rotating wheels 86, making it convenient to control the rotation of the two threaded screws 84 at the same time, ensuring the synchronicity and stability of the sub-bed lifting and lowering.

[0022] As one implementation method in this embodiment, please refer to Figure 4 and Figure 5 As shown, two second connecting frames 89 are rotatably connected between every two inner bearings 73 via a rotating shaft. First connecting frames 88 are rotatably connected to both sides of the outer wall of the sliding frame 85. The end of the second connecting frame 89 away from the inner bearing 73 is rotatably connected between the two first connecting frames 88 via a rotating shaft. Two fixed brackets 881 are symmetrically fixed to the lower bottom ends of the first support plate 42 and the second support plate 43. The end of the two first connecting frames 88 away from the sliding frame 85 is rotatably connected between every two fixed brackets 881 via a rotating shaft. After the sub-bed frame 41 is lifted, it is flush with the top of the mother bed frame 1.

[0023] It should be noted that the two second connecting frames 89 rotating between every two inner bearings 73 are cleverly coordinated with the first connecting frames 88 rotating on both sides of the outer wall of the sliding frame 85. When the sliding frame 85 moves under the action of the lifting mechanism 8, the power can be accurately transmitted through the rotation of the first and second connecting frames, driving the first support plate 42 and the second support plate 43 to rise and fall smoothly. The fixed brackets 881 at the bottom of the first support plate 42 and the second support plate 43 are rotatably connected with the first connecting frame 88, which further enhances the structural stability and ensures that the force on each component is uniform during the lifting process, and there will be no shaking or jamming.

[0024] Working principle: The support mechanism 7 and the lifting mechanism 8, and the sub-bed mechanism 4 are slidably retracted to the bottom of the mother bed frame 1 with the help of the support mechanism 7. When needed, the sub-bed mechanism 4 is slid out from inside the mother bed frame 1. In order to make the top of the mother bed frame 1 and the top of the sub-bed frame 41 flush, the retraction sleeve 9, the spline sleeve 10 and the spline shaft 87 are rotated. The two sets of spline shafts 87 synchronously drive the rotating wheel 86 and the threaded screw 84 to rotate. The two threaded screws 84 drive the sliding frame 85 to make linear motion. When the sliding frame 85 moves in a straight line, it drives the first connecting frame 88 to move in a straight line and squeezes the fixed bracket 881, causing the first connecting frame 88 and the second connecting frame 89 to move in an arc. After the fixed bracket 88 is squeezed by the first connecting frame 88, it pushes the second support plate 43 and the first support plate 42 to rise, thereby realizing the lifting and lowering movement of the sub-bed frame 41 and achieving the purpose of making the tops of the mother bed frame 1 and the sub-bed frame 41 flush. During use, the user can retract one of the spline sleeves 10 to enter the retractable sleeve 9, then pull the two positioning pins 49 out of the insertion hole 48 of the second support plate 43, and then rotate the spline shaft 87 located below the second support plate 43 to drive the threaded screw 84 to rotate. This operation is the same as the above, except that the end of the second support plate 43 will move in an arc shape, so that the back of the second support plate 43 is tilted, making the user more comfortable to use. Meanwhile, four sets of guide rails 47 are symmetrically placed on one side of the first support plate 42 and the second support plate 43 inside the sub-bed frame 41. Four collection boxes 45 are slidably connected to the outer walls of every two guide rails 47, which can be used to store items. Multiple positioning holes 46 are evenly opened at the top of the sub-bed frame 41, and multiple detachable guardrails 44 are inserted accordingly. When in use, these guardrails can be placed inside the collection boxes 45.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
