Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Referring to fig. 1, in one embodiment of the present application, there is provided an electric bed including a bed frame including a support frame 1, support bars and links, and a bed board including a back plate 7, a seat plate 8 and a thigh plate 9;
The support frame 1 is provided with a fixed seat 11, the back plate 7 is rotatably arranged on the fixed seat 11, the seat plate 8 is rotatably connected with the support frame 1 through at least two support rods, and the back plate 7 is rotatably connected with one support rod or the seat plate 8 through a connecting piece and is used for driving the support rod or the seat plate 8 to move;
the seat plate 8 is connected with the thigh plate 9 and is used for driving the thigh plate 9 to move, and the thigh plate 9 is rotatably connected with the support frame 1 through the third support rod 4;
When the electric bed is in an initial state, in the direction towards the thigh plate 9, an included angle between the support rod and the support frame 1 is not more than 90 degrees, and the inclination direction of the third support rod 4 is opposite to the inclination direction of the support rod.
In this embodiment, the electric bed comprises a bed frame and a bed board, the bed frame is used for supporting the bed board, and the bed board is used for bearing the body of a user. The bed frame comprises a supporting frame 1, a supporting rod and a connecting rod, and the bed board comprises a back board 7, a seat board 8, a thigh board 9 and a shank board 10. Specifically, the support frame 1 is provided with a fixing seat 11, and the back plate 7 is rotatably arranged on the fixing seat 11, so that a balance beam structure similar to a teeterboard is formed between the back plate 7 and the fixing seat 11, and a supporting point of the fixing seat 11 to the back plate 7 does not fall at the tail end of the back plate 7. The seat 8 is rotatably connected to the support frame 1 via at least two support bars, such as a first support bar 2 and a second support bar 3, respectively, and the back plate 7 is rotatably connected to the first support bar 2 or the seat 8 via a connecting member, such as a first connecting rod 5, which in this embodiment may be a hinged connection. Preferably, the connection point of the connection member with the back plate 7 is arranged at the end of the back plate 7 near the seat plate 8. The back plate 7 establishes position association with the seat plate 8 through the connection between the first connecting rod 5 and the first supporting rod 2, under the condition that the back plate 7 is kept unchanged, the first connecting rod 5 can have a tensile force on the first supporting rod 2, so that the first supporting rod 2 is limited by the first connecting rod 5 and cannot perform rotational movement, further the first supporting rod 2 supports the seat plate 8, and under the condition that the seat plate 8 is fixed, the second supporting rod 3 connected with the seat plate 8 naturally cannot perform rotational movement. Seat 8 is connected, e.g. hinged, to thigh panel 9, so that seat 8 can drive thigh panel 9 in a corresponding movement. The thigh board 9 is rotatably connected with the support frame 1 through the third support bar 4, so that a seesaw-like balance beam structure is formed between the third support bar 4 and the thigh board 9, and the supporting point of the third support bar 4 to the thigh board 9 is not located at the tail end of the thigh board 9. The thigh panel 9 and the shank panel 10 are rotatably connected, for example by means of a hinge. In this embodiment, the arrangement direction of the first support bar 2, the second support bar 3, and the third support bar 4 has certain requirements. Specifically, when the whole electric bed is in an initial state, that is, each bed board is in the same plane, as shown in fig. 1, in the direction towards the thigh board 9 or the shank board 10, the included angles between the first support rod 2, the second support rod 3 and the support frame 1 are not more than 90 degrees, that is, the connection ends of the first support rod 2, the second support rod 3 and the backboard 7 incline in the direction of the shank board 10, so that when the backboard 7 is tilted later, the first support rod 2 is pushed to rotate by the first connection rod 5, and then the seat board 8 can be lowered, thereby satisfying the technical effects of the application. The lengths and the inclination angles of the first support rod 2 and the second support rod 3 may be the same or different. The inclination direction of the third support rod 4 is opposite to the inclination direction of the first support rod 2 and/or the second support rod 3, and the seat plate 8 pushes the thigh plate 9 to move rightwards when sliding rightwards and descending, so that the third support rod 4 is driven to rotate, the included angle between the third support rod 4 and the support rod in the direction towards the calf plate 10 is reduced, namely the vertical distance from the support point between the third support rod 4 and the thigh plate 9 to the support frame 1 is increased, and the relative height between the thigh plate 9 and the seat plate 8 is increased. In the electric bed of this embodiment, when the relative height between the back plate 7 or the thigh plate 9 and the seat plate 8 is adjusted, one end of the back plate 7 is tilted, and since the support of the back plate 7 is realized by the fixing seat 11 in the middle area, the other end of the back plate 7 is lowered when one end of the back plate 7 is tilted, in the same principle as a seesaw. In the descending process of the other end of the back plate 7, the first connecting rod 5 is driven to push the first supporting rod 2 to move rightwards, and as the seat plate 8, the first supporting rod 2, the second supporting rod 3 and the supporting frame 1 form a parallelogram structure, under the pushing of the first connecting rod 5, the whole seat plate 8 slowly descends along with the reduction of the included angle between the first supporting rod 2, the second supporting rod 3 and the supporting frame 1, so that relative height change is generated between the back plate 7 and the seat plate 8 at the same time, and larger relative height is achieved on the premise that the inclination angle change of the back plate 7 is small. Similarly, since the seat plate 8 is hinged to the thigh plate 9, and the thigh plate 9 is rotatably connected to the support frame 1 through the third support rod 4, in the descending process of the seat plate 8, the displacement of the seat plate 8 pushes the thigh plate 9 to move rightward, so that the connecting end of the third support rod 4 and the thigh plate 9 also moves rightward, the included angle between the whole third support rod 4 and the support frame 1 becomes smaller in the direction towards the lower leg plate 10, and the end of the thigh plate 9 hinged to the seat plate 8 descends along with the descending of the seat plate 8, so that the whole thigh plate 9 can tilt by taking the third support rod 4 as a support. the thigh plate 9 drives the shank plate 10 hinged with the thigh plate to perform corresponding inclination angle change in the tilting process, so that the inclination angle adjustment of the whole electric bed is completed.
Further, the electric bed further comprises a lower leg plate 10, a connecting plate 12 and a second connecting rod 6, wherein the thigh plate 9 is rotatably connected with the lower leg plate 10 through the connecting plate 12, and the connecting plate 12 is rotatably connected with the third supporting rod 4 through the second connecting rod 6.
In this embodiment, the electric bed further comprises a connecting plate 12 and a second connecting rod 6, the shape of the connecting plate 12 preferably being triangular. The thigh plate 9 is rotatably connected with the shank plate 10 via a connecting plate 12, and the connecting plate 12 is also rotatably connected with the third support bar 4 via a second link 6. According to the above description, during the tilting of the back plate 7, the end of the thigh plate 9 close to the shank plate 10 is tilted, and the angle between the third support bar 4 and the support frame 1 in the direction toward the shank plate 10 is gradually reduced, that is, the third support bar 4 moves rightward as a whole around the connection point between itself and the support frame 1, and pushes the second link 6 connected to itself to move rightward as well. Because the connection end of the thigh plate 9 and the thigh plate 10 is tilted, the length of the second connecting rod 6 is fixed, so that the second connecting rod 6 generates a pulling force on the connecting plate 12, so that the connecting plate 12 rotates around the connection point of the connecting plate 12 and the thigh plate 9, and the included angle between the thigh plate 9 and the thigh plate 10 is driven to be smaller, namely the gradient of the thigh plate 10 is increased.
Further, the overall shape of the connecting plate 12 is triangular, and the connection parts of two adjacent sides of the connecting plate 12 are rounded.
In this embodiment, the overall shape of the connecting plate 12 is triangular, and the connection points of the connecting plate 12 and the thigh plate 9, the shank plate 10 and the second connecting rod 6 respectively correspond to three sharp corner areas of the triangle, that is, the three connection points are respectively located in the intersection areas of two adjacent sides of the triangle. The connecting plate 12 is triangular, so that the stability of the whole structure after the thigh plate 9, the shank plate 10 and the second connecting rod 6 which are respectively connected with the connecting plate can be improved. The connection parts of the adjacent two sides of the connecting plate 12 are arranged in a round angle, so that the edge transition of the connecting plate 12 is smooth, and the injury to a user is not easy to cause.
Further, one end of the connecting plate 12 is hinged to the thigh plate 9, and the other end of the connecting plate 12 is fixedly connected to the shank plate 10.
In this embodiment, the connection end of the connection plate 12 and the thigh plate 9 is hinged, and the connection end of the connection plate 12 and the shank plate 10 is fixedly connected. When the thigh plate 9 is tilted, the connection plate 12 rotates around the connection point with the thigh plate 9 under the tension of the second link 6. Meanwhile, since the connecting plate 12 is fixedly connected with the shank plate 10, the connecting plate 12 drives the shank plate 10 to correspondingly rotate in the rotating process, so that the shank plate 10 is correspondingly inclined.
Further, the electric bed further comprises a driving piece 13, one end of the driving piece 13 is hinged to the supporting frame 1, the other end of the driving piece 13 is hinged to the backboard 7, and the driving piece 13 is used for supporting the backboard 7 to move.
In this embodiment, the electric bed further comprises a driving member 13, such as an electric supporting rod and a pneumatic pushing rod, wherein one end of the driving member 13 is hinged with the supporting frame 1, and the other end is hinged with the backboard 7. When the driving piece 13 works, one end of the supporting back plate 7 is tilted, so that the other end of the back plate 7 descends by taking the fixing seat 11 as a supporting point, and the angles of the rest parts of the bed plate are adjusted through the connecting rod and the supporting rod. In the embodiment, the electric bed can drive the angle adjustment of the rest parts of the bed board by means of the connection relation between the connecting rod and the supporting rod only by arranging one driving piece for driving the back plate 7, so that the production cost is effectively saved.
Further, when the electric bed is in the initial state, the included angle between the third support rod 4 and the support frame 1 is greater than 120 degrees in the direction towards the lower leg plate 10.
In this embodiment, the third support bar 4 is disposed obliquely. Preferably, when the electric bed is in the initial state, the angle between the third support rod 4 and the support frame 1 is greater than 120 degrees in the direction towards the lower leg plate 10. When the back plate 7 is tilted, the seat plate 8 drives the thigh plate 9 to tilt and simultaneously pushes the thigh plate 9 to move rightwards, so that the third support rod 4 is driven to rotate around the connection point of the third support rod 4 and the support frame 1. The angle between the third support bar 4 and the support frame 1 becomes smaller in the direction toward the lower leg plate 10. Since the initial included angle is larger than 120 degrees, the third supporting rod 4 has enough travel to lift the thigh plate 9 in the moving process, and the relative height between the thigh plate 9 and the seat plate 8 is greatly increased on the premise of small change of the inclination angle of the thigh plate 9.
Further, the distance from the connection point of the back plate 7 and the fixing seat 11 to the two end points on the same side of the back plate 7 is the same.
In this embodiment, the distance from the connection point of the back plate 7 and the fixing base 11 to the two end points on the same side of the back plate 7 is the same, i.e. the connection point of the back plate 7 and the fixing base 11 is located in the middle area of the back plate 7. Because the support point of the fixing seat 11 to the backboard 7 is in the middle area of the backboard 7, when one end of the backboard 7 is tilted, the gap between the whole backboard 7 and the seat 8 is the smallest after the other end is lowered, and the gap is half of the gap between the adjacent beds supported by the cantilever mechanism, so that the possibility of the user being clamped and injured by the gap is reduced.
Further, the electric bed further comprises a mattress and a bed surrounding, wherein the mattress is paved on the bed board, the bed surrounding is arranged at the edge of the bed board and surrounds the mattress, and the height of the bed surrounding is consistent with the thickness of the mattress.
In this embodiment, the electric bed further comprises a mattress and a bed cover, wherein the mattress is laid on the bed board and is used for receiving the body of a user. The bed is enclosed and arranged at the edge of the bed board to integrally form and enclose the mattress. Preferably, the height of the bed cover in the embodiment is consistent with the thickness of the mattress, so that when the inclination angle of the bed plate changes, if the change amplitude of the inclination angle does not exceed the thickness range of the original mattress, the bed cover surrounding the mattress can block the gap generated by the change of the inclination angle of the bed plate, thereby protecting users or other articles from being clamped by the gap and improving the safety performance of the electric bed in use.
Further, the support rods comprise a first support rod 2 and a second support rod 3, the first support rod 2 is arranged at one end of the seat plate 8 close to the back plate 7, the second support rod 3 is arranged at one end of the seat plate 8 close to the thigh plate 9, and the length and the inclination angle of the first support rod 2 and the second support rod 3 are the same.
In this embodiment, the first support rod 2 is disposed at one end of the seat 8 close to the back plate 7, and the second support rod 3 is disposed at one end of the seat 8 close to the thigh plate 9, that is, the first support rod 2 and the second support rod 3 are disposed at two ends of the seat 8, so that a longer distance is provided between the first support rod 2 and the second support rod 3, and the seat 8 can be supported more firmly as a whole. Preferably, the lengths and the inclination angles of the first support rod 2 and the second support rod 3 are the same, so that the seat plate 8, the first support rod 2, the second support rod 3 and the support frame 1 integrally form a parallelogram structure, and the seat plate 8 is supported to stably lift.
Further, the distance from the connecting point of the third support rod 4 and the thigh plate 9 to the two end points on the same side of the thigh plate 9 is the same.
In this embodiment, the distance from the connection point of the third support rod 4 and the thigh plate 9 to the two end points on the same side of the thigh plate 9 is the same, that is, the connection point of the third support rod 4 and the thigh plate 9 is located in the middle of the thigh plate 9. Because the third support rod 4 is arranged in the middle area of the thigh plate 9 on the supporting point of the thigh plate 9, when one end of the thigh plate 9 descends, the gap between the whole thigh plate 9 and the seat plate 8 is the smallest after the other end of the thigh plate is tilted, and the gap is half of the gap between the adjacent bed plates supported by the cantilever mechanism, so that the safety performance of the electric bed in use can be effectively improved, and a user or other objects are prevented from being clamped.
In the electric bed provided by the embodiment, the seat plate 8 is rotatably connected with the support frame 1 through the first support rod 2 and the second support rod 3 respectively; the backboard 7 is rotatably arranged on the fixed seat, and the tail end of the backboard 7 is rotatably connected with the first support rod 2 through the first connecting rod 5; the seat plate 8 is hinged with the thigh plate 9, and the thigh plate 9 is rotatably connected with the support frame 1 through the third support rod 4; thigh plate 9 is rotatably connected with shank plate 10. When the relative height between the backboard 7 and the seat board 8 needs to be adjusted, the backboard 7 is tilted, and as the support of the backboard 7 is realized by the fixing seat 11 in the middle area, when one end of the backboard 7 is tilted, the other end of the backboard 7 is lowered. In the descending process of the other end of the back plate 7, the first connecting rod 5 is driven to push the first supporting rod 2 to move rightwards, and as the seat plate 8, the first supporting rod 2, the second supporting rod 3 and the supporting frame 1 form a parallelogram structure, under the pushing of the first connecting rod 5, the whole seat plate 8 slowly descends along with the reduction of the included angle between the first supporting rod 2, the second supporting rod 3 and the supporting frame 1, so that relative height change is generated between the back plate 7 and the seat plate 8 at the same time, and larger relative height is achieved on the premise that the inclination angle change of the back plate 7 is small. Similarly, since the seat plate 8 is hinged to the thigh plate 9, and the thigh plate 9 is rotatably connected to the support frame 1 through the third support rod 4, the thigh plate 9 can be tilted upward with the third support rod 4 as a fulcrum in the descending process of the seat plate 8, so that a large relative height is obtained, and energy consumption can be effectively saved.
