[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Figure 1 A structural schematic diagram of an embodiment of the present invention is shown. This embodiment relates to a lifting bed, which is used for medical beds, nursing beds, furniture beds, etc. The lifting bed has a lifting structure that can realize automatic lifting of the bed body in the vertical direction. At the same time, it has a flipping structure that can realize flipping of the supporting mesh plates constituting the bed body, so that the supporting mesh plates have different inclination angles to meet usage requirements. The overall structure of the lifting bed is simple, the degree of automation is high, and the cost is low.

The lifting structure is arranged below the bed main body, and the lifting structure is connected to the bed main body. Through the action of the lifting structure, it is contracted or expanded to drive the bed main body to perform lifting and lowering movements, thereby realizing automatic lifting of the bed main body; the flipping structure is connected to the bed main body, and the flipping structure is arranged below the bed main body. Through the action of the flipping structure, part of the supporting mesh plates of the bed main body are driven to flip, so that part of the supporting mesh plates are tilted and have different angles to meet the user's back and / or legs being tilted at a certain angle, so that the lifting bed meets the use requirements and improves the comfort of the user.

[0034] Among them, such as Figure 1-5 As shown, the lifting structure includes a first bracket 1 and a second bracket 2 arranged relatively to each other, at least two groups of lifting components arranged between the first bracket 1 and the second bracket 2, a synchronous transmission component and a driving component. The setting of the first bracket 1 and the second bracket 2 plays the role of a supporting skeleton, which is convenient for the installation of multiple groups of lifting components. Each group of lifting components is connected to the first bracket 1 and the second bracket 2 respectively, and the setting of the first bracket 1 can play a supporting role, which is convenient for the installation of the bed body. The first bracket 1 is connected to the bed body, and the bed body is arranged on a side surface of the first bracket 1 away from the second bracket 2, so that the bed body moves with the movement of the first bracket 1; the synchronous transmission components are respectively connected to the multiple groups of lifting components, and the driving components are respectively connected to the second bracket 2 and any lifting component. Through the synchronous transmission component, the driving component drives the group of lifting components and other groups of lifting components to move simultaneously, so that the first bracket 1 and the second bracket 2 move relative to each other, and the first bracket 1 remains in a horizontal state during the movement, and the bed body is lifted and lowered in the vertical direction.

[0035] A driving component and a synchronous transmission component are provided, and the driving component drives a group of lifting components connected thereto to move, and through the motion transmission of the synchronous transmission component, drives multiple groups of lifting components to move simultaneously, so that the first bracket 1 is relatively close to or away from the second bracket 2, and then the bed body is relatively close to or away from the second bracket 2, so that the bed body is raised or lowered in the vertical direction, realizing the lifting of the bed body. The entire lifting structure adopts a mechanical structure with a simple structure, easy operation and use, and is made of common steel material, which is easy to prepare and has low production cost.

[0036] Specifically, there are multiple groups of the above-mentioned lifting components, and the multiple groups of lifting components are arranged in sequence along the length direction of the first bracket 1, that is, the multiple groups of lifting components are arranged along the length direction of the bed body, providing upward force and downward force to the bed body from different positions, and the multiple groups of lifting components act simultaneously, so that the second bracket 2 is evenly stressed and can be lifted and lowered smoothly in a horizontal state, thereby enabling the bed body to be lifted and lowered smoothly without tilting during the lifting process.

[0037] In some feasible embodiments, there are two groups of lifting components, which are arranged at both ends of the first bracket 1 along the length direction of the first bracket 1, and control the two ends of the first bracket 1 to rise and fall at the same time, so that the first bracket 1 remains in a horizontal state during the rising or falling process.

[0038] The above-mentioned first bracket 1 and second bracket 2 are both frame structures. The shape of the first bracket 1 and the shape of the second bracket 2 can be rectangular, polygonal, circular, or other shapes. They are selected and set according to actual needs, and no specific requirements are made here. In some feasible embodiments, the first bracket 1 and the second bracket 2 are both rectangular frame structures, which are formed by four connecting rods fixedly connected end to end in sequence. In order to facilitate the installation of the lifting assembly and the installation of the bed body, a first support rod 19 and a second support rod 20 are provided on the first bracket 1. The first support rod 19 and the second support rod 20 are both arranged along the length direction of the first bracket 1. The first support rod 19 and the second support rod 20 are both located in the frame of the first bracket 1, and the first support rod 19 and the second support rod 20 are preferably arranged in parallel.

[0039] The above-mentioned lifting assembly includes a first rotating member 5 rotatably arranged on the first bracket 1, a second rotating member 6 rotatably arranged on the second bracket 2, at least two groups of folding assemblies and at least two groups of first swinging members 13, wherein the first rotating member 5 can rotate relative to the first bracket 1, and the second rotating member 6 can rotate relative to the second bracket 2. The arrangement of the first rotating member 5 and the second rotating member 6 facilitates the installation of the folding assembly, and the folding assembly is fixedly connected to the first rotating member 5 and the second rotating member 6 respectively. The rotation of the first rotating member 5 and the second rotating member 6 drives the folding assembly to move, and the folding assembly is opened or folded, thereby realizing the movement of the first bracket 1 relative to the second bracket 2 and realizing the rising or falling of the first bracket 1. One end of the first swinging member 13 is rotatably connected to the second bracket 2, and the other end of the first swinging member 13 is connected to the folding assembly. The arrangement of the first swinging member 13 limits the opening or folding action of the folding assembly and controls the opening angle of the folding assembly.

[0040] The first rotating member 5 and the second rotating member 6 are both shaft structures. The two ends of the first rotating member 5 are respectively rotatably connected to the first support rod 19 and the second support rod 20 of the first bracket 1, so that the first rotating member 5 can rotate relative to the first support rod 19 and the second support rod 20. That is, the first rotating member 5 is arranged along the width direction of the first bracket 1. Preferably, the first rotating member 5 can be rotatably connected to the first support rod 19 and the second support rod 20 respectively through bearings. The two ends of the second rotating member 6 are respectively rotatably connected to a group of oppositely arranged connecting rods of the second bracket 2, so that the second rotating member 6 can rotate relative to the second bracket 2. That is, the second rotating member 6 is arranged along the width direction of the second bracket 2. Preferably, the second rotating member 6 can be rotatably connected to the group of oppositely arranged connecting rods through bearings.

[0041] In order to facilitate the installation of the folding assembly and keep the first bracket 1 in a horizontal state during the lifting process, preferably, the first rotating member 5 and the second rotating member 6 are arranged in parallel.

[0042] The aforementioned folding assemblies are provided in multiple sets, each of which is sequentially arranged along the axial direction of the first rotating member 5, that is, along the width direction of the first bracket 1. Force is applied to the first rotating member 5 from multiple positions along the width direction of the first bracket 1, so that the force is evenly applied to the first rotating member 5 along the axial direction of the first rotating member 5, and the first rotating member 5 remains horizontal during the lifting process. When multiple sets of folding assemblies are provided, they are arranged in a similar manner so that they behave in the same manner during movement, thereby ensuring smooth lifting and lowering of the first rotating member 5.

[0043] In some feasible embodiments, the number of the folding components is preferably two groups, and the two groups of folding components are respectively arranged at the ends close to both ends of the first rotating member 5.

[0044] The above-mentioned folding assembly includes a first folding member 8 and a second folding member 7 connected to each other. The first folding member 8 is fixedly connected to the first rotating member 5, and the second folding member 7 is fixedly connected to the second rotating member 6. The first folding member 8 and the second folding member 7 can rotate relative to each other, so that the first folding member 8 and the second folding member 7 can be relatively close to or away from each other, to achieve opening or folding, thereby achieving the lifting and lowering of the first rotating member 5. The first folding member 8 and the second folding member 7 are both rod structures. One end of the first folding member 8 is fixedly connected to the first rotating member 5, and the other end of the first folding member 8 is rotatably connected to one end of the second folding member 7 through a rotating shaft. The other end of the second folding member 7 is fixedly connected to the second rotating member 6. The fixed connection method of the first folding member 8 to the first rotating member 5 and the fixed connection method of the second folding member 7 to the second rotating member 6 can be fixedly connected by connecting members such as bolts, or both can be welded, or both can be interference fit with the shaft hole, or both can be other fixed connection methods. The selection is made according to actual needs and no specific requirements are made here.

[0045] The first swinging member 13 is a rod structure. One end of the first swinging member 13 is rotatably connected to the side frame of the second bracket 2, so that the first swinging member 13 can rotate relative to the second bracket 2. The first swinging member 13 and the second bracket 2 can be connected by a rotating shaft, or by a bearing, or by other rotatable connection methods. The selection is based on actual needs and no specific requirements are made here. The other end of the first swinging member 13 is rotatably connected to the first folding member 8, so that the first swinging member 13 can rotate relative to the first folding member 8. When the first folding member 8 rotates relative to the second folding member 7, the first swinging member 13 is driven to rotate, so that the first folding member 8, the second folding member 7, the first swinging member 13 and the second bracket 2 form a four-bar linkage structure, realizing the simultaneous action of the folding assembly and the first swinging member 13, and realizing the movement of the first bracket 1 relative to the second bracket 2.

[0046] In two adjacent groups of lifting components, the setting method of the folding components in one group of lifting components is different from the setting method of the folding components in the other group of lifting components. In the two groups of lifting components, the intersection of the first folding component 8 and the second folding component 7 of the folding component is relatively set and located in the space between the two groups of lifting components, so that in the two groups of lifting components, the corresponding first rotating components 5 have opposite rotation directions, and the corresponding second rotating components 6 have opposite rotation directions, so that the first bracket 1 can be lifted and lowered in the vertical direction without shaking.

[0047] The drive assembly is a power source that provides power for the movement of the lifting assembly, enabling automatic lifting of the bed body. The drive assembly includes a drive member 9 and a second swinging member 4 rotatably connected to the drive member 9. The second swinging member 4 is fixedly connected to the second rotating member 6. The drive member 9 is fixedly mounted on the second bracket 2. The output end of the drive member 9 is rotatably connected to one end of the second swinging member 4, and the other end of the second swinging member 4 is fixedly connected to the second rotating member 6, allowing the second swinging member 4 to swing relative to the drive member 9.

[0048] In some feasible embodiments, preferably, the driving member 9 is a telescopic motor, and the output shaft of the telescopic motor is rotatably connected to one end of the second swinging member 4 through a rotating shaft. The other end of the second swinging member 4 and the second rotating member 6 can be fixedly connected by a connecting member such as a bolt, or by welding, or by interference fit of the shaft hole, or by other fixed connection methods. The selection is made according to actual needs and no specific requirements are made here.

[0049] The telescopic rod of the telescopic motor extends, driving the second swinging member 4 to swing, the second swinging member 4 drives the second rotating member 6 to rotate, the second rotating member 6 rotates, driving the second folding member 7 to swing, the second folding member 7 drives the first folding member 8 to swing, the first folding member 8 drives the first swinging member 13 to swing, the first swinging member 13 swings, and at the same time the first folding member 8 drives the first rotating member 5 to rotate, and the rotation direction of the first rotating member 5 is opposite to that of the second rotating member 6, so that the end of the first folding member 8 connected to the first rotating member 5 is away from the end of the second folding member 7 connected to the second rotating member 6, that is, the first rotating member 5 is away from the second rotating member 6, and the first bracket 1 moves with the movement of the first rotating member 5, and the first bracket 1 is away from the second bracket 2, thereby realizing the rising of the first bracket 1.

[0050] The above-mentioned synchronous transmission assembly includes a connecting member 10, a third swinging member 3 and a fourth swinging member 12 that are rotatably connected to the connecting member 10, the third swinging member 3 is fixedly connected to the second rotating member 6 of one lifting assembly, and the fourth swinging member 12 is fixedly connected to the second rotating member 6 of another lifting assembly for power transmission. The connecting member 10 is a rod-shaped structure, and the connecting member 10 is arranged along the length direction of the first bracket 1. The third swinging member 3 and the fourth swinging member 12 are respectively arranged at both ends of the connecting member 10. The third swinging member 3 and the fourth swinging member 12 are both rod-shaped structures. One end of the third swinging member 3 is rotatably connected to the connecting member 10 through a rotating shaft, and the third swinging member 3 and the connecting member 10 can rotate relative to each other. The other end of the third swinging member 3 is fixedly connected to the second rotating member 6. The fixed connection method can be fixed connection through a connecting member 10 such as a bolt, or welding, or interference fit of the shaft hole, or other fixed connection methods, which can be selected according to actual needs and are not specifically required here. One end of the fourth swing member 12 is rotatably connected to the connecting member 10 via a rotating shaft, and the fourth swing member 12 and the connecting member 10 can rotate relative to each other. The other end of the fourth swing member 12 is fixedly connected to the second rotating member 6 of another group of lifting components. The fixed connection method can be a fixed connection through a connecting member 10 such as a bolt, or welding, or interference fit of the shaft hole, or other fixed connection methods, which can be selected according to actual needs and no specific requirements are made here.

[0051] The second rotating member 6 connected to the third swing member 3 rotates, driving the third swing member 3 to swing, the third swing member 3 drives the connecting member 10 to swing, the connecting member 10 drives the fourth swing member 12 to swing, and the fourth swing member 12 drives the second rotating member 6 connected thereto to rotate, and power is input, so that the lifting component group is activated, driving the first bracket 1 to rise and fall.

[0052] The third swing member 3 is intersected with the fourth swing member 12, and the third swing member 3 is extended along the radial direction of the second rotating member 6 toward the first bracket 1, and the fourth swing member 13 is extended along the radial direction of the second rotating member 6 toward the second bracket 2 away from the first bracket 1, so that the rotation direction of the second rotating member 6 connected to the third swing member 3 is opposite to the rotation direction of the second rotating member 6 connected to the fourth swing member 12, so that the rotation directions of the second swing members 7 in the two adjacent groups of lifting assemblies are opposite, so that the force directions at both ends of the first bracket 1 are opposite, thereby ensuring that the first bracket 1 will not shake during the lifting process and can be lifted and lowered smoothly in the vertical direction.

[0053] The above-mentioned bed body includes multiple support mesh panels 15 to support different body parts of the user, such as the back, buttocks, legs, etc. The multiple support mesh panels 15 are arranged on the first bracket 1, and the multiple support mesh panels 15 are arranged in sequence along the length direction of the first bracket 1. The multiple support mesh panels 15 are arranged on the side surface of the first bracket 1 away from the second bracket 2. The width of the support mesh panel 15 is greater than the distance between the first support rod 19 and the second support rod 20, and the width of the support mesh panel 15 is less than the width of the first bracket 1, so that the support mesh panel 15 corresponds to the inside of the first bracket 1, and the first support rod 19 and the second support rod 20 both support the support mesh panel 15. The support mesh panel 15 is arranged on the first support rod 19 and the second support rod 20, and the support mesh panel 15 is in contact and cooperated with the first support rod 19 and the second support rod 20 so that the support mesh panel 15 can be flipped relative to the first support rod 19 and the second support rod 20.

[0054] The support mesh 15 comprises a mesh frame, a grid connected to the mesh frame, and a fixing member 17. The shape of the grid is consistent with the shape of the mesh frame. The grid is fixedly arranged in the mesh frame, and the lateral sides of the grid are fixedly connected to the inner lateral sides of the mesh frame, forming the basic structure of the support mesh 15. The number of fixing members 17 is at least two, and the two ends of the fixing member 17 are respectively fixedly connected to the mesh frame. The fixing members 17 are arranged along the length direction of the first bracket 1. The fixing members 17 are arranged in sequence along the width direction of the first bracket 1. The arrangement of the fixing members 17 facilitates the connection of the support mesh 15 with the flipping structure. The flipping structure drives the support mesh 15 to flip, that is, the flipping structure drives the support mesh 15 to rotate to a tilted state. Among the multiple support meshes 15, any two or more adjacent support meshes 15 are connected in sequence. When one support mesh 15 flips, it can drive the other support meshes 15 to move. Alternatively, the support meshes 15 are not connected to each other, and each support mesh 15 can flip independently.

[0055] In some feasible embodiments, the number of the fixing members 17 is two, and the fixing members 17 are rod structures; the number of the supporting mesh plates 15 is four, two of which are connected so that the two connected supporting mesh plates 15 move at the same time, and the other two supporting mesh plates 15 may have no connection relationship and can move separately.

[0056] There are multiple flipping structures mentioned above, and one flipping structure is connected to a supporting mesh plate 15 to drive the supporting mesh plate 15 to flip. The number of flipping structures is selected according to the connection relationship of the multiple supporting mesh plates 15 and the number of supporting mesh plates 15 that are set to be flippable among the multiple supporting mesh plates 15. No specific requirements are made here.

[0057] The above-mentioned flip structure includes a flip driving member 11, a fifth swinging member 14 rotatably connected to the flip driving member 11, and a rotating member 16. The rotating member 16 is provided on the first bracket 1 and can rotate relative to the first bracket 1. That is, the rotating member 16 is an axis structure. The two ends of the rotating member 16 are rotatably connected to the first support rod 19 and the second support rod 20 respectively. The rotating member 16 can rotate relative to the first support rod 19 and the second support rod 20. One end of the fifth swinging member 14 is rotatably connected to the flip driving member 11, and the other end of the fifth swinging member 14 is fixedly connected to the rotating member 16. When the flip driving member 11 is actuated, the fifth swinging member 14 is driven to swing, and the fifth swinging member 14 drives the rotating member 16 to rotate. A connecting rod 18 is fixedly connected to the rotating member 16, and the connecting rod 18 is fixedly connected to the fixed member 17. When the rotating member 16 rotates, the connecting rod 18 rotates, and the connecting rod 18 drives the fixed member 17 to rotate, thereby driving the support mesh plate 15 to rotate around the rotating member 16. The flip drive member 11 is fixedly mounted on the first bracket 1 and is located on the side of the first bracket 1 facing the second bracket 2. The flip drive member 11 is positioned between the first bracket 1 and the second bracket 2 to prevent interference between the flip drive member 11 and the support mesh 15. During installation, a mounting member 21 is connected between the first support rod 19 and the second support rod 20. The mounting member 21 is a rod structure, and the flip drive member 11 is fixedly connected to the mounting member 21. At the same time, the mounting member 21 supports the support mesh 15.

[0058] In some feasible embodiments, preferably, the flip driving member 11 is a telescopic motor, which is a commercially available product and is selected according to actual needs. The rotation angle of the rotating member 16 is controlled by the length of the telescopic rod of the telescopic motor, thereby controlling the rotation angle of the supporting mesh plate 15 and controlling the tilt angle of the supporting mesh plate 15.

[0059] In some feasible embodiments, there are two flipping structures. When the two flipping structures are installed, the rotating parts 16 of the two flipping structures are arranged opposite to each other, the telescopic rods of the flipping driving parts 11 have opposite telescopic directions, and the two flipping structures are respectively connected to a supporting mesh plate 15. The two supporting mesh plates 15 are not adjacent to each other. There is at least one supporting mesh plate 15 between the two supporting mesh plates 15. Under the drive of the two flipping structures, the rotation directions of the two supporting mesh plates 15 connected thereto are opposite.

[0060] In some feasible embodiments, the rotational connection between the aforementioned components may be hinged.

[0061] The lifting bed further includes a front railing and a rear railing arranged at both ends of the first bracket 1 and guardrails arranged on the left and right sides of the first bracket 1.

[0062] The lifting bed also includes a dining table connected to the first bracket 1. The dining table is rotatably connected to the first bracket 1, so that the dining table can be stored and the tabletop of the dining table can be placed horizontally for use.

[0063] The following is a detailed description of the working process of a lifting bed with two lifting assemblies and two flip structures. It is assumed that the two lifting assemblies are the first lifting assembly and the second lifting assembly, and the first lifting assembly and the second lifting assembly are respectively located at the two ends of the length direction of the first bracket 1; the first lifting assembly and the second lifting assembly each have two folding assemblies, and it is assumed that the two folding assemblies are the first folding assembly and the second folding assembly, and the first folding assembly and the second folding assembly are arranged at both ends of the first rotating member 5.

When the second rotating member 6 rotates, the second folding member 7 of the first folding assembly and the second folding member 7 of the second folding assembly are driven to rotate clockwise at the same time, and the second folding member 7 of the first folding assembly drives the first folding member 8 of the first folding assembly to rotate counterclockwise, and the first folding member 8 drives the first swinging member The first folding member 13 rotates clockwise, and at the same time, the first folding member 8 drives the first rotating member 5 to rotate counterclockwise, and the first swinging member 13 controls the rotation angle of the first folding member 8 relative to the second folding member 7; at the same time, the second folding member 7 of the second folding assembly drives the first folding member 8 of the second folding assembly to rotate counterclockwise, and the first folding member 8 drives the first swinging member 13 to rotate clockwise, and the first folding member 8 drives the first rotating member 5 to rotate counterclockwise, and the first swinging member 13 controls the rotation angle of the first folding member 8 relative to the second folding member 7, so that the first rotating member 5 is lifted up;

[0065] When the second rotating member 6 rotates clockwise, it drives the third swinging member 3 to rotate clockwise, and drives the fourth swinging member 12 to rotate counterclockwise through the connecting member 10. The fourth swinging member 12 drives the second rotating member 6 of the second lifting assembly to rotate counterclockwise. The second rotating member 6 drives the second folding member 7 of the first folding assembly and the second folding member 7 of the second folding assembly to rotate counterclockwise at the same time. The second folding member 7 of the first folding assembly drives the first folding member 8 connected thereto to rotate clockwise. The first folding member 8 drives the first rotating member 5 to rotate clockwise. At the same time, the first folding member 8 drives the first swinging member 13 to rotate counterclockwise. Rotation, the first swinging member 13 controls the rotation angle of the first folding member 8 relative to the second folding member 7; at the same time, the second folding member 7 of the second folding assembly drives the first folding member 8 connected thereto to rotate clockwise, and the first folding member 8 drives the first rotating member 5 to rotate clockwise. At the same time, the first folding member 8 drives the first swinging member 13 connected thereto to rotate counterclockwise, and the first swinging member 13 controls the rotation angle of the first folding member 8 relative to the second folding member 7, so that the first rotating member 5 of the second lifting assembly rises; the first lifting assembly and the second lifting assembly act simultaneously, so that the first bracket 1 remains in a horizontal state and rises smoothly;

[0066] When the lifting bed needs to be lowered, the driving member 9 moves in the reverse direction, the telescopic rod is retracted, and the above-mentioned components all move in the reverse direction to lower the first bracket 1;

[0067] When one or more supporting mesh plates 15 need to rotate, the flipping structure connected to the supporting mesh plate 15 moves, the flipping driving member 11 moves, the telescopic rod extends, drives the fifth swinging member 14 to swing, the fifth swinging member 14 drives the rotating member 16 to rotate, and the connecting rod 18 rotates with the rotation of the rotating member 16, thereby causing the supporting mesh plate 15 connected to the connecting rod 18 to rotate around the rotating member 16, thereby realizing the flipping of the supporting mesh plate 15.

[0068] When the two supporting mesh plates 15 are connected, when one of the supporting mesh plates 15 rotates, the other supporting mesh plate 15 can be driven to rotate, so that the connection point of the two supporting mesh plates 15 rises upward.

[0069] Due to the adoption of the above technical solution, the lifting bed has a lifting structure, and the lifting structure has at least two groups of lifting components, and the multiple groups of lifting components are arranged along the length direction of the bed body. The driving component drives one group of lifting components to move, and uses the synchronous transmission component for power to drive the other groups of lifting components to move at the same time. The folding components in the two adjacent groups of lifting components are relatively arranged, and the movement directions are opposite, so that the first bracket rises or falls relative to the second bracket, and the first bracket remains in a horizontal state and is lifted in the vertical direction, which can achieve the function of vertical lifting. The structure is simple, the manufacturing cost is low, it is made of mechanical components, has fewer electrical components, and has a wider lifting range; it has at least two flipping structures, one flipping structure is connected to a supporting mesh plate, and the supporting mesh plate is driven to flip around the flipping structure through the movement of the flipping structure. The structure is simple, the manufacturing cost is low, it is made of mechanical components, has fewer electrical components, and has a wider lifting range.
