Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a smart bed. Background Technology

[0002] Existing smart lift beds use push-rod motors to raise and lower bed boards corresponding to different parts of the body, allowing for zoned adjustment of the headboard, backboard, and thighboard to meet diverse user needs. However, these smart lift beds lack a rocking function, failing to meet the needs of some users, such as those who want to rock infants to sleep. Furthermore, some existing smart rocking beds only allow the bed board to rock left and right as a whole, without adjusting the angle of the bed boards to different parts of the body. This means users can only experience the rocking function while lying flat, resulting in a poor user experience. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a smart bed, as shown in the following figure. Figures 1-4The smart bed includes a fixed support frame 100, a rocking drive device 200, a rocking mechanism, a lifting mechanism, and a bed board mechanism. One end of the rocking mechanism is connected to the output shaft of the rocking drive device 200; the rocking mechanism is movably connected to the fixed support frame 100; the lifting mechanism is mounted on the rocking mechanism; the bed board mechanism is mounted on the lifting mechanism; the lifting mechanism supports the bed board mechanism and drives it to move up and down; under the action of the rocking drive device 200, the rocking mechanism drives the lifting mechanism and the bed board mechanism to rock relative to the fixed support frame 100. Specifically, the fixed support frame 100 is not only movably connected to the rocking mechanism but also provides stable support for it. In this smart bed, the lifting mechanism supports the bed board mechanism and drives it to move up and down, allowing users to adjust the shape of the bed board mechanism according to their needs. Simultaneously, under the action of the rocking drive device 200, the rocking mechanism in this smart bed drives the lifting mechanism and the bed board mechanism to rock relative to the fixed support frame 100, achieving overall rocking of the bed board mechanism and the lifting mechanism, simulating a cradle-like swaying motion to help users relax, aid sleep, and improve sleep comfort. Furthermore, it can meet the needs of different groups in different scenarios. For example, for infants and young children, it can rock them to sleep; for people with light sleep or who are easily awakened, the rocking function can extend the time of deep sleep. Compared with traditional smart beds that only have lifting or rocking functions, this smart bed integrates lifting and rocking functions. It can not only lift or rock the bed board mechanism independently, but also achieve the coordinated work of lifting and rocking of the bed board mechanism, which greatly improves the user experience.

[0021] Furthermore, referring to Figures 3-5 The swing mechanism includes a swing linkage assembly 310, a swing arm linkage 320, and a swing support frame 330. A lifting mechanism is mounted on the swing support frame 330. One end of the swing linkage assembly 310 is mounted on the output shaft of the swing drive device 200, and the other end is movably mounted to the swing support frame 330. One end of the swing arm linkage 320 is rotatably connected to the fixed support frame 100, and the other end is rotatably connected to the swing support frame 330. Multiple swing arm linkages 320 are provided. The output shaft of the swing drive device 200 drives the swing linkage assembly 310 to rotate, and the swing linkage assembly 310 cooperates with the multiple swing arm linkages 320 to make the swing support frame 330 swing relative to the fixed support frame 100. Specifically, under the combined action of the rocking drive device 200, the rocking linkage assembly 310 and the swing arm linkage 320, the rocking support frame 330 drives the lifting mechanism mounted on the rocking support frame 330 to rock relative to the fixed support frame 100, thereby driving the bed board mechanism mounted on the lifting mechanism to rock, meeting the user's needs for assisting sleep, rocking to sleep and relaxing nerves when lying on the bed board mechanism.

[0022] Furthermore, referring to Figures 4-7The swing support frame 330 includes: a main swing arm bracket 331, a guide rail 332, a secondary swing arm bracket 333, and a connecting bracket 334. Both ends of the main swing arm bracket 331 are rotatably connected to the swing arm connecting rod 320; the guide rail 332 allows one end of the swing connecting rod assembly 310 to be movably mounted; the guide rail 332 is fixedly mounted on the side of the main swing arm bracket 331 facing the swing drive device 200; both ends of the secondary swing arm bracket 333 are rotatably connected to the swing arm connecting rod 320; the connecting bracket 334 is located between the main swing arm bracket 331 and the secondary swing arm bracket 333; one end of the connecting bracket 334 is connected to the main swing arm bracket 331, and the other end is connected to the secondary swing arm bracket 333; at least one connecting bracket 334 is provided. Specifically, the guide rail 332 has a groove on the side facing the swing connecting rod assembly 310 for one end of the swing connecting rod assembly 310 to be inserted. In this embodiment, the rocking drive device 200 is activated. The output shaft of the rocking drive device 200 drives one end of the rocking linkage assembly 310 to rotate, and the other end of the rocking linkage assembly 310 drives the guide rail 332 to rock. Under the synchronous swinging action of the rocking arm linkage 320, the main rocking arm bracket 331, the connecting bracket 334, and the auxiliary rocking arm bracket 333 are driven to rock relative to the fixed support frame 100, ultimately driving the lifting mechanism and the bed board mechanism to rock. In this embodiment, two connecting brackets 334 are provided. In some embodiments, four connecting brackets 334 may also be provided.

[0023] In this embodiment, four swing arm connecting rods 320 are provided; one end of two of the swing arm connecting rods 320 is rotatably connected to both ends of the main swing arm bracket 331; one end of the other two swing arm connecting rods 320 is rotatably connected to both ends of the auxiliary swing arm bracket 333. The other ends of the four swing arm connecting rods 320 are rotatably connected to the fixed support frame 100. The four swing arm connecting rods 320 correspond to the two ends of the main swing arm bracket 331 and the auxiliary swing arm bracket 333, respectively, and evenly transfer the weight of the main swing arm bracket 331, the auxiliary swing arm bracket 333, and the lifting mechanism and bed board mechanism located above the main swing arm bracket 331 and the auxiliary swing arm bracket 333 to the fixed support frame, avoiding deviation during the swinging process and avoiding deformation and wear caused by local overload.

[0024] Furthermore, referring to Figures 6-10The rocking linkage assembly 310 includes: a rocking generating linkage 311, a fastener 312, a bearing spacer 313, and a limiting bearing 314. One end of the rocking generating linkage 311 is sleeved on the output shaft of the rocking drive device 200; one end of the fastener 312 is fitted inside the other end of the rocking generating linkage 311, with the other end located within the guide rail 332; the bearing spacer 313 is sleeved on the end of the fastener 312 near the rocking generating linkage 311; the limiting bearing 314 is sleeved on the end of the fastener 312 located within the guide rail 332; the outer peripheral wall of the limiting bearing 314 abuts against the inner wall of the guide rail 332. Specifically, the swing-generating link 311 converts the rotational power of the swing drive device 200 into reciprocating swing motion. This motion is then transmitted through the fastener 312 and bearing spacer 313, causing the limiting bearing 314 to slide within the guide rail 332. Since the outer peripheral wall of the limiting bearing 314 abuts against the inner wall of the guide rail 332, the limiting bearing 314 drives the guide rail 332 to perform reciprocating swing motion. With the coordinated action of the swing arm link 320, this further drives the main swing arm bracket 331 to perform reciprocating swing motion. During the reciprocating swing motion of the swing-generating link 311 driven by the output shaft of the swing drive device 200, the limiting bearing 314 generates an axial force. One end of the fastener 312 is fitted into the other end of the swing-generating link 311, with the other end located within the guide rail 332. The head of the fastener 312 cooperates with the bearing spacer 313 to restrict the axial movement of the limiting bearing 314, ensuring the coaxiality of the limiting bearing 314 and the end of the swing-generating link 311 fitted with the fastener 312. In this embodiment, the fastener 312 is a shoulder screw, and the limiting bearing 314 is a rubber-coated bearing. The rubber layer on the outer ring of the rubber-coated bearing enhances the fit with the inner wall of the guide rail 332, and the elastic properties of the rubber can buffer the impact between the limiting bearing 314 and the guide rail 332. In addition, the rubber-coated bearing also has noise reduction characteristics. In some embodiments, the fastener 312 can also be a stop screw, and the limiting bearing 314 can also be other bearing components.

[0025] Furthermore, referring to Figures 7-8 This smart bed also includes: a fixing plate 610, a first sensor 620, a second sensor 630, and a sensing element 640. The fixing plate 610 is mounted on the fixed support frame 100, and one side is used for mounting the rocking drive device 200. The fixing plate 610 has a through hole 611 for the output shaft of the rocking drive device 200 to extend towards the guide rail 332. The first sensor 620 is mounted on the upper side of the fixing plate 610; the second sensor 630 is mounted on the lower side of the fixing plate 610; the sensing element 640 is mounted on the end of the rocking generating link 311 for mounting the fastener 312 and rotates with the rotation of the rocking generating link 311; the central axis of the first sensor 620, the hole axis of the through hole 611, and the central axis of the second sensor 630 are located on the same vertical line (see reference). Figure 7 as well as Figure 8 (Vertical axis A in the diagram). In this embodiment, the upper and lower ends of the fixed plate 610 are respectively provided with an upper extension plate and a lower extension plate, and the first sensor 620 and the second sensor 630 are respectively mounted on the upper extension plate and the lower extension plate. The positions of the first sensor 620 and the second sensor 630 are set as the origin of the rocking drive device 200 (the reference position for the output shaft or load movement of the rocking drive device 200). When the sensing element 640 engages with the first sensor 620 or the second sensor 630, it is determined that the rocking drive device 200 has returned to the origin. At this time, the rocking drive device 200 does not need to output torque to maintain the stability of the rocking mechanism, avoiding the rocking drive device 200 being under stress for a long time and reducing the wear of the rocking drive device 200. In addition, the rocking drive device 200 also has a self-locking function to ensure that the rocking drive device 200 is not activated when at the origin position, so as to ensure that the user will not rock when getting on or off the bed or rolling over in bed.

[0026] In this embodiment, the sensing element 640 is a baffle, and the first sensor 620 and the second sensor 630 are configured as slot-type photoelectric sensors. In some embodiments, the first sensor 620 and the second sensor 630 can also be infrared through-beam sensors. In some embodiments, the first sensor 620 and the second sensor 630 can also measure the rotational speed of the output shaft of the rocking drive device 200 through the periodic pulse signal generated by the rotation of the connecting rod 311 as the baffle rotates. Each rotation of the sensing element 640 passes through the two sensors sequentially, triggering a pulse. The controller can record the pulse interval time, calculate the rotational speed of the rocking drive device 200, and then combine it with the transmission ratio to convert it into the rocking frequency. The rocking frequency is correlated with the user's sleep state to record the optimal sleep-inducing frequency. In this embodiment, the rocking drive device 200 is configured as a self-locking geared motor. In some embodiments, the rocking drive device 200 can also be configured as a servo motor.

In this embodiment, the two support columns 420 in each group are used to connect the main swing arm bracket 331 and the lifting support seat 410, and the auxiliary swing arm bracket 333 and the lifting support seat 410, respectively. This not only provides stable support for the lifting support seat 410, but also ensures that the lifting support seat 410 stably follows the swing of the main swing arm bracket 331 and the auxiliary swing arm bracket 333. A bed board mechanism is mounted on the first lifting frame 450, the second lifting frame 460, the third lifting frame 470, and the fourth lifting frame 480.
