The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 3, an electric bed for turning over in synchronous motion includes a bed frame 1, a middle bed plate 21, a front end bed plate, a rear end bed plate, a guide frame 4, a hinge 7, a front driving member 31, and a rear driving member 32.

Wherein, bedstead 1 is the support body that has the stabilizer blade, and well bed board 21 fixed connection is in the mid portion of bedstead 1, and first preceding bed board 22 and well bed board 21 rotate to be connected, and the first preceding bed board 23 one end of first preceding bed board 22 is kept away from 21 one end and is rotated to be connected, and the second preceding bed board 23 of 23 other end is the free end and well bed board 21 set up the head and the tail both ends of first preceding bed board 22 respectively.

When using an electric bed with synchronous motion and turning, it is generally desirable that the bed has two forms, one is a "bed state" in which the bed board is all flattened for a person to lie flat, and the other is a sofa state in which the front-end bed board and the middle bed board corresponding to the back of the person are turned over to form a certain angle.

For this reason, in the related design, a driving device such as a linear driver is used to support the bed board to form the backrest; that is, let straight line driver one end and bedstead 1 articulated, the other end rotates with the bed board that can rotate to be connected, and then under the design thinking that straight line driver both ends homoenergetic rotated for when rotating the bed board, make straight line driver can support the bed board, and then play the function that lets the bed board can be changed to "sofa state" from "bed state".

The above design has the problem that, because the bed board is directly connected with the power output shaft of the linear driver, when the linear driver toggles the bed board to an inclined state to serve as a backrest, a user leans against the backrest, and the linear driver bears the gravity of most users, so that the service life of the linear driver and the tightness of the air cylinder are required to be higher. While the driving parts such as the linear driver can be changed into a screw rod and a nut driven by a motor; however, when such a driving device is used on this part, it is large and has low continuity, and it is difficult to lengthen the length of the driving end to play a supporting role when the user pulls the bed plate.

Therefore, aiming at the problems, the application designs the following technical scheme:

the front end bed plate is rotatably connected with the middle bed plate 21, and has a first state of being flattened opposite to the middle bed plate 21 and a second state of being inclined opposite to the middle bed plate 21;

a front driving part 31 is provided on the frame 1, and the front driving part 31 drives the guide frame 4 to move along a first straight line direction to have a first position and a second position;

the hinge piece 7 is respectively connected to the guide frame 4 and the front end bed board, and respectively forms rotary connection with the front end bed board and the guide frame 4, and a connecting line of a connecting point of the hinge piece 7 and the front end bed board and a connecting point of the hinge piece 7 and the guide frame 4 has a first angle and a second angle which are different relative to a first linear direction;

when the front-end bed plate and the middle bed plate 21 are in a first state, the guide frame 4 is in a first position along a first linear direction, and a connecting line of a connecting point of the hinge piece 7 and the front-end bed plate and a connecting point of the hinge piece 7 and the guide frame 4 has a first angle relative to the first linear direction; when the front-end bed plate and the middle bed plate 21 are in the second state, the guide frame 4 is in the second position along the second linear direction, and the connecting line of the connecting point of the hinge piece 7 and the front-end bed plate and the connecting point of the hinge piece 7 and the guide frame 4 has a second angle relative to the first linear direction.

In this way, when the front driving piece 31 moves along with the smooth pushing guide moving guide frame 4, along with the relative transmission of the hinge piece 7, the pushing force transmitted to the front end bed board by the front driving piece 31 through the hinge piece 7 gradually decreases, and the pressure applied to the output end of the driving piece by the corresponding front end bed board can be smaller and smaller. When the front bed plate is initially pushed to move, it is naturally desirable that the force applied to the front bed plate by the front drive member 31 is larger, and when the front bed plate is changed to the second state, the resistance applied to the drive member by the front bed plate is smaller.

Therefore, the hinge frame is rotationally designed, when the front driving piece 31 just starts to push the guide frame 4, the first angle is small, so that the front driving piece 31 can transmit the force to the front end bed plate to be large, and when the guide frame 4 moves to the second position, the second angle is large, so that the front driving piece 31 can transmit the force to the front end bed plate, and the corresponding front end bed plate transmits the force to the front driving piece 31 to be small, so that the pressure born by the front driving piece 31 is small when a user leans on the front end bed plate.

Further, the first angle is defined as α1, 0.ltoreq.α1.ltoreq.10.

The second angle is defined as alpha 2, alpha 2 being more than or equal to 60 degrees and less than or equal to 90 degrees; in this way, at a minimum of 60 ° of the second angle, it is ensured that the hinge 7 has a sufficiently large inclination angle when supporting the front bed plate, so as to convert most of the pressure of most users into pressure in the vertical direction.

The following is a specific structure.

Referring to fig. 1 and 3, the front bed plate includes a first front bed plate 21 and a second front bed plate 22, and the first front bed plate 21 and the second front bed plate 22 are rotatably connected.

The bed frame 1 is provided with a guide bar 12 arranged along the length direction of the bed frame 1, and the guide frame 4 is slidably arranged on the guide bar 12, specifically, the guide frame 4 includes a guide housing 41 and a connecting rod 42. The guide rod 12 is provided with two guide shells 41, the two guide shells 41 are sleeved on the guide rod 12 to form sliding connection with the guide rod 12, and the head end and the tail end of the guide rod 12 are respectively connected to the two guide shells 41. Thus, the guide frame 4 can slide along the longitudinal direction of the bed frame 1.

Referring to fig. 1 and 3, the hinge 7 includes a connection bar 71, a rotation bar 72, and a hinge bar 73, wherein the connection bar 71 is fixedly connected to the first front bed plate 22, and both ends of the rotation bar 72 are rotatably connected to the connection bar 71 and the guide housing 41, respectively. Thus, the first front bed 22 can be connected to the guide frame 4 in a rotatable manner. One end of the hinge rod 73 is rotatably connected with the guide rod 12, and the other end is connected to the second front bed plate 23 and forms a rotary connection with the second front bed plate 23. The front driving member 31 is fixedly connected to the frame 1, and in this embodiment, the front driving member 31 is fixedly connected to the guide bar 12, and the power output shaft of the front driving member 31 is rotatably connected to the guide frame 4.

Therefore, the guide shell 41 is slidably disposed on the guide rod 12, so that when the first front bed plate 21 and the second front bed plate 22 are turned to the backrest state, the pressure of the user against the second front bed plate will be mostly changed into the pressure pressing against the guide rod 12, and only a small part of the force needs to be borne by the front driving member 31, so that the requirement on the front driving member 31 is relatively low in practical use.

Moreover, when the front driving piece 31 is damaged, the power output shaft of the front driving piece 31 cannot bear pressure to retract, and when the front driving piece 31 retracts, the moving speed of the guide frame 4 is slower, and the safety is higher because of the friction between the guide frame 4 and the guide rod 12.

In the related design, the front driving member 31 and the backrest are in direct contact with each other, so that the above-mentioned problems can be easily avoided.

Thus, the present application has two states:

bed state: in this state, the angle at which the first front bed plate 22 and the middle bed plate 21 are unfolded is a flat angle, the first front bed plate 22 is arranged along the length direction of the guide rod 12, while the angle at which the second front bed plate 23 and the first front bed plate 22 are unfolded is a flat angle, and the second front bed plate 23 is arranged along the length direction of the guide rod 12; at this time, the guide frame 4 is moved toward the side close to the front driver 31, and the driver jack of the front driver 31 is compressed; however, since the first front bed plate 22, the second front bed plate 23, and the middle bed plate 21 are already laid flat as one plate body, the thrust applied to the first front bed plate 22 and the second front bed plate 23 cannot guide the relative rotation of the first front bed plate 22 and the second front bed plate 23, and thus the first front bed plate 22 and the second front bed plate 23 can be positioned in this state smoothly.

In a sofa state, the user pulls the second front bed plate 23 upward, the flat angle state between the second front bed plate 23 and the first front bed plate 22 is broken, and the flat angle state between the second front bed plate 23 and the middle bed plate 21 is changed, so that under the action of the front driving piece 31, the power output rod of the front driving piece 31 pushes the guide frame 4 to move, and after the guide frame 4 moves in a direction far away from the front driving piece 31, the rotating rod 72 and the hinging rod 73 start to rotate from a position parallel to the guide rod 12 in a direction perpendicular to the guide rod 12, and further the first front bed plate 22 and the second front bed plate 23 are supported.

To sum up, the above working process is analyzed, and the first front bed board 22 and the middle bed board 21 are set to be in a rotating form, so that when the first front bed board 22 turns up a part of distance under the action of external force, the front driving piece 31 will push the guide frame 4 to move, so as to push the first front bed board 22 to turn up, and thus, the sofa is very convenient to transfer from the bed state to the sofa state.

Furthermore, the design of the hinge member 7 can also enable the guide frame 5 to drive the first front bed plate 22 and the second front bed plate 23 to synchronously rotate when pushing the hinge member 7 to move, so that the consistency of the whole device is better, and the turning arrangement of a plurality of bed plates can be completed under the condition that only one linear driver is needed to be provided.

Furthermore, the bed frame 1 is also provided with a supporting block 11, the first front bed board 22 and the second front board 23 which can be supported by the supporting block 11 are supported by the supporting block 11, the supporting block 11 is fixedly connected on the bed frame 1,

furthermore, in the actual use process, the backrest is only folded upwards in the sofa state, so that the sofa is not fit for actual life. In the present application, the first rear bed plate 24 and the second rear bed plate 25 are also bent into a wavy shape, so that when the user uses the sofa-type sofa, the user can support the lower legs and thighs of the user by the first rear bed plate 24 and the second rear bed plate 25 in a meandering manner through the first rear bed plate 24 and the second rear bed plate 25 which are arranged in a wavy manner.

Specifically, the first rear bed board 24 is rotationally connected with the middle bed board 21, the second rear bed board 25 is rotationally connected with the first rear bed board 24, the connecting rod 6 is rotationally connected with the middle of the second rear bed board 25, the connecting rod 6 is rotationally connected with the bed frame 1, the rear driving piece 32 is rotationally connected with the bed frame 1, and the rebound shaft of the rear driving piece 32 and the first rear bed board 24 form rotational connection.

In this way, in the bed state, the first rear bed plate 24 and the second rear bed plate 25 are flat angles, and the rebound shaft of the rear driving member 32 is compressed, and the first rear bed plate 24, the second rear bed plate 25 and the middle bed plate 21 are in a flat structure, so that the rebound shaft of the driving member cannot move under the action of no external force. When the sofa is required to be used in a sofa state, the second rear bed plate 25 can be turned downwards only by pulling the lower end of the second rear bed plate 25 from top to bottom, and meanwhile, the first rear bed plate 24 is tilted, so that the rebound shaft of the rear driving piece 32 continuously pushes the second rear bed plate 25 to turn.

Specifically, the front driving member 31 and the rear driving member 32 are linear drivers, and in other embodiments, the front driving member and the rear driving member may be disposed on a spring, an oil cylinder, or other elastic structures capable of absorbing pressure.

The foregoing description is only of the preferred embodiments of the present disclosure and description of the principles of the technology being employed. It will be appreciated by those skilled in the art that the scope of the utility model in the embodiments of the present disclosure is not limited to the specific combination of the above technical features, but encompasses other technical features formed by any combination of the above technical features or their equivalents without departing from the spirit of the utility model.
