Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1 to 5The utility model provides a technical scheme: a swing bed with multidirectional swing, including frame 1, frame 1 is installed with: backing plate 2, first drive mechanism, limiting mechanism, connecting plate 3, bed plate 5 and second drive mechanism, backing plate 2 is installed at the bottom end of the inside of frame 1, first drive mechanism sets up at the top of backing plate 2, limiting mechanism is installed at the four corner parts of the top of backing plate 2, and is overlapped with first drive mechanism, connecting plate 3 is installed at the top of first drive mechanism, and two through slots 4 are set up in connecting plate 3, bed plate 5 is movably set up at the top of connecting plate 3, and the both sides of bed plate 5 are also provided with foldable guardrails 21, and second drive mechanism is installed at the bottom end of bed plate 5 and connecting plate 3 respectively.

[0020] Need to explain, when the swing bed works, first, first drive mechanism operates at the top of backing plate 2, drives the movement of the connecting plate 3 connected with it, and the through slot 4 on the connecting plate 3 provides a certain guide and activity space for the movement of bed plate 5, so that bed plate 5 can move at the top of connecting plate 3. At the same time, the first drive mechanism and the second drive mechanism installed at the bottom end of the bed plate 5 and the connecting plate 3 and perpendicular to each other work together, the second drive mechanism can exert force on the bed plate 5 in the direction perpendicular to the first drive mechanism, and the two work together to make the bed plate 5 swing only in the x-axis or only in the y-axis or in the x-axis and y-axis directions at the same time, forming an arc-shaped swing path, and the limiting mechanism installed at the top of the four corner parts of the backing plate 2 is overlapped with the first drive mechanism, which plays a limiting and auxiliary movement role, finally realizes the multidirectional swing effect of the bed plate 5, such as front and rear swing, left and right swing, arc swing, and can adjust the swing speed and set the timing function through relevant setting, the foldable guardrail 21 provides safety guarantee, reduces the risk of falling out of bed for the elderly due to turning over or bed swing, avoids injury; gives psychological comfort, the width of the bed plate can be according to actual situation facilities, can be designed to be one meter wide, small space enhances the safety of the elderly, improves sleep quality; It is convenient to use and personalized demand, and can be folded and unfolded as needed. While ensuring safety, it does not affect the activity of the old people, and has high practicality.

[0021] In some examples, the first drive mechanism includes: a drive motor 6, a rotating part 7, a seating seat 8, a moving rod 9, and a linking assembly, the drive motor 6 is embedded in the inside of the backing plate 2, the end of the rotating part 7 is fixedly arranged on the driving end of the drive motor 6, a plurality of seating seats 8 are fixedly arranged on the top of the backing plate 2, two moving rods 9 are movably installed on the plurality of seating seats 8, and the two ends are fixedly connected with the bottom end of the connecting plate 3, and the linking assembly is installed on the two moving rods 9 and the rotating part 7.

[0022] It should be noted that when the first driving mechanism of the swing bed is working, the driving motor 6 embedded in the inner side of the pad plate 2 is started, and the driving end drives the rotating part 7 fixedly connected at the end to start rotating. At this time, the connecting assembly converts the rotating movement of the rotating part 7 into the movement of the moving rod 9 on the mounting seat 8, thereby driving the connecting plate 3 to move correspondingly, providing power support for the swing of the bed plate 5, and then cooperating with the second driving mechanism to realize the multi-directional swing function of the bed plate 5. The rotating speed of the driving motor 6 can be adjusted according to the actual use. In terms of rotating speed adjustment, the frequency converter rectifier inverter changes the frequency by changing the frequency of alternating current, and the like. The automatic production line can set the control of the conveyor belt motor speed through the operation panel.

[0023] In some examples, the connecting assembly includes a movable block 10 and a moving frame 11. The movable block 10 is rotatably installed at the other end of the rotating part 7. The moving frame 11 is fixedly connected between the two moving rods 9 at both ends, has a through hole in the middle, and is movably connected with the movable block 10.

[0024] It should be noted that during the working process of the first driving mechanism, when the rotating part 7 rotates under the driving of the driving motor 6, the movable block 10 rotatably installed at the other end of the rotating part 7 moves. Since the moving frame 11 is fixedly connected between the two moving rods 9 at both ends, has a through hole in the middle, and is movably connected with the movable block 10, the movement of the movable block 10 interacts with the moving frame 11 through the through hole, so that the moving frame 11 moves correspondingly under the driving of the movable block 10, and then drives the two moving rods 9 connected thereto to move on the mounting seat 8, finally realizing the conversion of the rotation of the rotating part 7 into the movement of the moving rod 9, thereby providing power transmission for the swing of the bed plate 5 and assisting in realizing the swing action of the bed plate 5 in the relevant direction.

[0025] In some examples, the limiting mechanism includes a fixed seat 12 and an abutting wheel 13. The fixed seat 12 is provided at the four corner parts of the top end of the pad plate 2 in groups of two. The abutting wheel 13 is rotatably installed on the fixed seat 12 in groups of two, and the edge part is overlapped with the outer side of the outer wall of the two moving rods 9.

[0026] It should be noted that when the moving rod 9 in the first driving mechanism moves on the mounting seat 8, the edge part of the abutting wheel 13 is overlapped with the outer wall outside of the moving rod 9. With the movement of the moving rod 9, the abutting wheel 13 will rotate under the pushing of the moving rod 9, and the rotating direction is related to the moving direction of the moving rod 9. The abutting wheel 13 plays a limiting role on the moving rod 9, preventing the moving rod 9 from deviating or shaking excessively during movement, ensuring that the moving rod 9 can move stably along the predetermined track, thereby ensuring that the entire first driving mechanism can work normally and stably, providing reliable power transmission and motion support for the multi-directional swinging of the bed plate 5. When the moving rod 9 and the abutting wheel 13 move relatively, the moving rod 9 and the abutting wheel 13 generate rolling friction. Compared with sliding friction, the friction coefficient of rolling friction is significantly smaller, thereby effectively reducing the frictional force suffered by the moving rod 9 during movement. It helps to reduce the energy loss of the moving rod 9 during movement, so that the power of the first driving mechanism can be transmitted more efficiently, ensuring smooth swinging of the bed plate 5, and reducing the wear of the moving rod 9 and the abutting wheel 13, prolonging the service life of the related components, ensuring that the swing bed can operate stably for a long time, and continuously providing reliable multi-directional swinging function for users.

[0027] In some examples, the bottom end of the connecting plate 3 is provided with a limiting guide rail 14 parallel to the two through grooves 4, and the four corner parts of the top end are provided with a ball 15, which is overlapped with the bottom end of the bed plate 5.

[0028] It should be noted that during the operation of the swing bed, when the bed plate 5 moves at the top end of the connecting plate 3, the ball 15 can reduce the friction between the bed plate 5 and the connecting plate 3, making the movement of the bed plate 5 more smooth. At the same time, the ball 15 can freely roll under the pressure of the bed plate 5, while the limiting guide rail 14 limits the movement of the bed plate 5 in a specific direction, ensuring that the bed plate 5 can only move stably and orderly in the direction parallel to the through groove 4, avoiding deviation or shaking of the bed plate 5 during movement, providing guarantee for the stable movement of the bed plate 5 during multi-directional swinging, and further helping to realize the precise and stable multi-directional swinging function of the entire swing bed.

[0029] In some examples, the second driving mechanism comprises a cylinder 16, a hinge base 17, a rotating shaft 18, a rack 19 and a gear 20. The cylinder 16 is installed at the bottom end of the connecting plate 3 and is parallel to the two through grooves 4. The hinge bases 17 are fixedly arranged at the bottom end of the bed plate 5 and penetrate the two through grooves 4. The rotating shaft 18 is rotatably installed on the hinge bases 17 and is perpendicular to the cylinder 16, and the end thereof is movably connected with the two limiting guide rails 14. The two racks 19 are fixedly arranged at the top end of the pad plate 2 and are located directly below the two through grooves 4. The two gears 20 are fixedly sleeved on the outer wall of the rotating shaft 18 and are engaged with the two racks 19.

[0030] It should be noted that when the second driving mechanism is started, the cylinder 16 installed at the bottom end of the connecting plate 3 and parallel to the through groove 4 starts to work and pushes the connected parts to move. The hinge base 17 provides a rotatable installation position for the rotating shaft 18. The rotating shaft 18 rotates on the hinge base 17, and the end thereof is movably connected with the limiting guide rail 14, so that the rotating shaft 18 can move within a certain range along the direction of the limiting guide rail 14 during movement. At the same time, the rack 19 is engaged with the gear 20. When the cylinder 16 pushes the rotating shaft 18 to move, the rotating shaft 18 will rotate due to the engagement relationship between the gear 20 and the rack 19, and in turn drive the bed plate 5 to move along the direction parallel to the through groove 4 under the cooperation of the ball 15 and the limiting guide rail 14. The first driving mechanism and the second driving mechanism are perpendicular to each other, and the two mechanisms jointly act to enable the bed plate 5 to move in multiple directions, so as to achieve the multi-directional swinging effect of the swinging bed. As for the extension and retraction time of the cylinder 16, the solenoid control technology controls the power-on time of the solenoid through the control system, and the automatic packaging machine can control the extension and retraction of the cylinder 16 and time according to the control. The proportional solenoid control technology controls the gas flow in proportion to the size of the electric signal, and can accurately control the action of the cylinder 16 in precision machining equipment, and is widely used in many fields. The control of the cylinder 16 is a known technology in the art, and will not be described in detail here.
