Detailed Implementation

[0023] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 8 The present invention preferably provides a technical solution: a multi-link adaptive lumbar support mattress mechanism, comprising: a mattress frame 111; an adaptive adjustment pad assembly disposed within the mattress frame 111; and a linkage drive mechanism disposed within the mattress frame 111 for adjusting the local shape of the adaptive adjustment pad assembly to adapt to lumbar support in different postures; the linkage drive mechanism includes several linkage drive components independently installed at the bottom of the mattress frame 111 and in contact with the adaptive adjustment pad assembly, which, when a certain linkage drive component is adjusted, is used to adjust the shape of the adaptive adjustment pad assembly corresponding to that linkage drive component.

[0025] like Figure 1 , 3 As shown in Figures 5 and 8, the adaptive adjustment pad assembly and the linkage drive mechanism provided in this application are respectively assembled on the upper and lower parts of the pad frame 111 and are in contact with each other. Since the linkage drive mechanism includes several linkage drive assemblies independently installed at the bottom of the pad frame 111, such as... Figure 5 , 6 As shown in Figure 8, when a single linkage drive component is operated, the adaptive adjustment pad component corresponding to that linkage drive component can adjust its shape to provide lumbar support in that position, thereby improving sleep comfort. Since there are several linkage drive components, they can meet the lumbar support process in different postures and positions.

[0026] Furthermore, the adaptive adjustment pad assembly includes a support portion 112 and a flexible connection portion 113 that are fixed to the pad frame 111 and distributed sequentially at intervals, such as... Figure 1-8 As shown, several support parts 112 can contact several linkage drive components one by one. When the linkage drive components are running, under the action of the flexible connection part 113, the support parts 112 can adjust their height and tilt angle to meet the different needs of different people for lumbar support.

[0027] Furthermore, each linkage drive assembly includes two symmetrically distributed linkage drive members, each linkage drive member including an offset roller and a support block that contact the adjacent support 112; and a linkage component for lifting the offset roller and the support block;

[0028] Furthermore, each linkage component includes a first horizontal bar 214 fixed to the bottom of the inner frame 111, with first connecting rods 216 rotatably mounted at both ends of the first horizontal bar 214 via first rotating shafts 215; a second rotating shaft 217 disposed at the end of each first connecting rod 216 away from the first rotating shaft 215, wherein the offset roller is assembled between the two second rotating shafts 217; and a second horizontal bar 211 disposed at the bottom of the inner frame 111, with third connecting rods 213 rotatably mounted at both ends of the second horizontal bar 211 via third rotating shafts 212, wherein the support block is assembled between the two third connecting rods 213; it also includes a second connecting rod 220 rotatably mounted on each second rotating shaft 217, with the end of the second connecting rod 220 away from the second rotating shaft 217 rotatably mounted to the end of the third connecting rod 213 near the second horizontal bar 211 via a fourth rotating shaft 219; and an electric telescopic rod 221 is also disposed between each third rotating shaft 212 and its corresponding second rotating shaft 217.

[0029] like Figure 3 , 4 As shown in Figures 6 and 7, the two linkage drive components of each linkage drive assembly are symmetrically distributed. Each linkage drive component includes an offset roller and a support block that contact the adjacent support part 112; and a linkage component for lifting the offset roller and the support block. Therefore, when the linkage component is running, the two support parts 112 that contact the offset roller and the support block can be lifted and lowered synchronously, thereby realizing flexible adjustment of the waist support level.

[0030] The specific connecting rod components, specifically the first horizontal bar 214 and the second horizontal bar 211, are both fixed to the bottom of the inner frame 111, such as... Figure 4 , 7 As shown, two first connecting rods 216 and two third connecting rods 213 are rotatably mounted on opposite ends of the first horizontal bar 214 and the second horizontal bar 211, respectively. The second rotating shafts 217 mounted on opposite ends of the two first connecting rods 216 are used for mounting the offset rollers, and the two third connecting rods 213 are used for mounting the support blocks. At the same time, the second connecting rod 220 and the electric telescopic rod 221 mounted on the third connecting rod 213 are connected to the second rotating shaft 217 on the same side. Therefore, when the electric telescopic rod 221 moves forward and backward, since the first horizontal bar 214 and the second horizontal bar 211 are fixed, the electric telescopic rod 221 can push the first connecting rod 216 to deflect towards another set of connecting rod components. At this time, the offset roller between the two first connecting rods 216 pushes up the support part 112 that is in contact with it. At the same time, under the action of the second connecting rod 220, the electric telescopic rod 221 pulls the third connecting rod 213 upward and pushes up the support part 112 that is in contact with it, thus synchronously adjusting the shape of the corresponding adaptive adjustment pad assembly to achieve the effect of waist support.

[0031] Furthermore, the offset roller body includes a support roller 218 disposed between the two second rotating shafts 217, such as Figure 4 , 7 As shown.

[0032] Furthermore, the support block includes an assembly plate 224 fixed between the two third connecting rods 213, the assembly plate 224 having a plurality of assembly holes 225; bolts disposed inside each assembly hole 225; and support blocks 222 placed on the surface of the assembly plate 224. When the bolts pass through the assembly holes 225 and are threadedly connected to the screw holes at the bottom of the assembly plate 224, they are used for assembling and fixing the support blocks 222. Figure 8 As shown above, the support block 222 can be mounted on the mounting plate 224. When the two third links 213 deflect upwards, the support block 222 can press against the support part 112 in contact with it and cause the support part 112 to rise, thereby increasing the degree of support.

[0033] Furthermore, a vertical plate 226 is fixed to the middle of the two third links 213, such as... Figure 7 As shown, in order to improve the stability of the movement of the support block 222, a vertical plate 226 is installed in front of the support block 222 in the direction of movement to further support the support block 222.

[0034] Furthermore, the side wall of the pad frame 111 is provided with several control buttons 114, wherein each control button 114 corresponds to a certain linkage component and is used to adjust the extension and retraction degree of the second horizontal bar 211, such as... Figure 1 This is existing technology and will not be elaborated further.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0036] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
