Description

Technical Field

[0001] This utility model relates to the field of bed board technology, and more specifically, it relates to an intelligent bed board assembly with a lumbar support linkage structure. Background Technology

[0002] Most smart beds on the market consist of four panels: a backrest, a hiprest, a thighrest, and a calfrest. When the backrest of the smart bed is raised, the backrest lifts up, forming an angle with the hiprest. The mattress at this angle cannot fit against the bed board, causing the user to feel unsupported and unsupported in the lower back, leading to muscle compensation and fatigue. Furthermore, the mattress not fitting against the bed board results in uneven pressure on the mattress, shortening its lifespan.

[0003] In addition, existing smart beds with a four-panel structure have fabric coverings on the outside, and the fabric is glued to each panel to form a whole. This results in no gaps for ventilation, leading to poor breathability of the smart bed, a poor user experience, and a further shortened lifespan of the mattress. Utility Model Content

Example

[0030] Please see Figure 1-5 A smart bed board assembly with a lumbar support linkage structure includes a bed frame 1, a first drive assembly 2, a first bed board 3, a second bed board 4, and a linkage bed board 5. A linkage assembly 6 is provided between the linkage bed board 5 and the first bed board 3. The first drive assembly 2 is installed on the bed frame 1 and is used to drive the first bed board 3 to rise. The first bed board 3 is used to support the mattress and, under the action of the first drive assembly 2, drives the mattress to rise. The linkage bed board 5 is used to support the mattress at the angle between the first bed board 3 and the second bed board 4. The linkage assembly 6 is used to drive the linkage bed board 5 to rotate and rise when the first bed board 3 rises. The second bed board 4 is fixedly installed on the bed frame 1 and is used to support the mattress. The first drive assembly 2 includes a drive mechanism 201, a rotating shaft 202, and a rotating frame 203. The rotating frame 203 is fixedly sleeved outside the rotating shaft 202. The rotating shaft 202 is rotatably connected to the bed frame 1. The first bed board 3 is fixedly installed on the rotating frame 203. The drive mechanism 201 is a worm gear motor, and the output shaft of the worm gear motor is connected to the rotating shaft 202. The linkage assembly 6 includes a connecting rod 601, a fixed shaft 602, a positioning rod 603, a limiting seat 604, a movable rotating shaft 605, and a scissor-type linkage structure 606. The connecting rod 601 is fixedly mounted on the bed frame 1, the fixed shaft 602 is fixedly mounted on the rotating frame 203, the limiting seat 604 is fixedly connected to the linkage bed plate 5, and the limiting seat 604 has a limiting groove 607 for the movable rotating shaft 605 to roll. One end of the scissor-type linkage structure 606 is rotatably connected to the connecting rod 601, and the other end is fixedly connected to the movable rotating shaft 605. The middle section of 6 is rotatably connected to the fixed shaft 602. One end of the positioning rod 603 is fixedly installed on the linkage bed plate 5, and the other end is slidably connected to the rotating frame 203. It is used to guide the linkage bed plate 5 when it moves. The scissor linkage structure 606 includes a first link 6061 and a second link 6062. The first link 6061 is rotatably connected to the second link 6062. The first link 6061 is rotatably connected to the connecting rod 601. The second link 6062 is connected to the movable rotating shaft 605, and the middle section of the second link 6062 is rotatably connected to the fixed shaft 602.

[0031] When in use, the drive mechanism 201 is activated, causing the rotating shaft 202 and the rotating frame 203 to rotate around the axis of the rotating shaft 202. This, in turn, causes the first bed board 3 and the mattress to rise. When the rotating frame 203 rises, it causes the fixed shaft 602 to rotate upward. The distance between the fixed shaft 602 and the connecting rod 601 increases, and the scissor linkage structure 606 deforms accordingly. This pushes the linkage bed board 5 to move outward along the direction of the positioning rod 603, so that it presses against the mattress, providing effective support for the user's lumbar spine, preventing the user's lumbar muscles from compensating, improving the user's comfort, and ensuring that the mattress is evenly stressed, thus extending the mattress's lifespan.

[0032] Comparative example:

[0033] Please see Figure 6 Remove the linkage bed board 5, fix the first bed board 3 on the rotating frame 203, and fix the second bed board 4 on the bed frame 1.

[0034] When the rotating plate 203 rises, it also causes the first bed board 3 to rise. An angle is formed between the first bed board 3 and the second bed board 4. This angle forms a cavity between the mattress and the first bed board 3 and the second bed board 4, preventing the mattress from fitting snugly against the first bed board 3 and the second bed board 4. This results in uneven pressure on the mattress and a short lifespan.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
