Description

Electric bed capable of synchronously moving and turning

Technical Field

The application relates to the technical field of furniture, in particular to an electric bed capable of synchronously moving and overturning.

Background

Electric beds are a common kind of furniture and there are many kinds of furniture, among which the way of turning a bed plate in a flat state to form a backrest is the most common.

The structure of the product can refer to the electric bed with synchronous motion and turnover disclosed in the chinese patent document CN216494462U bed frame and the electric bed with synchronous motion and turnover. In the technical scheme, the main supporting device driver of the electric bed which synchronously moves and turns is set to be capable of rotating, so that when the backrest of the bed rotates to an inclined state, the arrangement direction of the driver also rotates to the inclined state;

thus, the above design results in that when a person leans against the backrest, the force for supporting the backrest needs to be provided by the power output shaft of the linear driver; therefore, the safety of the linear actuator is relatively high, when the linear actuator is damaged due to the fact that the linear actuator bears excessive pressure, the linear actuator starts to retract rapidly under the action of the pressure, and therefore the phenomenon that the supported backrest is folded rapidly to be in a flattened state can be caused, and a user can be injured easily.

There is no electric bed with synchronous motion turnover to reduce the pressure at the output end of the driving member.

Referring to fig. 1 to 3, an electric bed for synchronous movement and turnover includes a bed frame 1, a middle bed plate 21, a front bed plate, a rear bed plate, a guide frame 4, a hinge member 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 bed board 23 one end and the first preceding bed board 22 one end of keeping away from 21 rotate to be connected before the second, and the 23 other end sets up the head and the tail both ends of first preceding bed board 22 respectively for bed board 23 and well bed board 21 before the free end second.

When the electric bed which is turned over by synchronous movement is used, the bed is expected to have two forms, namely a bed state that the bed board is completely flattened and is used for people to lie flat, and a sofa state that the front end bed board and the middle bed board which correspond to the back of a human body are turned over at a certain angle to form a backrest.

For this reason, in the related art, a driving device such as a linear actuator is used to support the bed plate to form a backrest; that is, let linear drive ware one end and bedstead 1 articulated, the other end with can the pivoted bed board rotate and connect, and then under the homoenergetic pivoted design in linear drive ware both ends for when rotating the bed board, make linear drive ware can support the bed board, and then play and let the bed board can follow the function that "bed state" changed to "sofa state".

The above design has the following problems that the requirements on the service life, stability and safety of the linear driver are high because the linear driver shifts the bed board to the inclined state to serve as the backrest, and the user leans on the backrest, and the linear driver actually bears the weight of most users. Although the driving piece such as a linear driver can be changed into a screw rod and a nut which are driven by a motor; however, when the driving device is used on the component, the size is large, the continuity is low, and the length of the driving end is difficult to extend along with the pulling of the bed plate by a user so as to play a supporting role.

Therefore, in order to solve the above problems, the following technical solutions are designed:

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

the front driving piece 31 is arranged on the bedstead 1, and the front driving piece 31 drives the guide frame 4 to move along a first linear direction so as to have a first position and a second position;

the hinged part 7 is respectively connected to the guide frame 4 and the front end bed plate and is respectively in rotary connection with the front end bed plate and the guide frame 4, and a connecting line of the connecting point of the hinged part 7 and the front end bed plate and a connecting point of the hinged part 7 and the guide frame 4 has a first angle and a second angle which are different relative to the first straight line 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 between the 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 board and the middle bed board 21 are in the second state, the guide frame 4 is in the second position along the second linear direction, and a second angle is formed between a connecting point of the hinge member 7 and the front end bed board and a connecting point of the hinge member 7 and the guide frame 4 relative to the first linear direction.

Thus, when the front driving part 31 moves in the smooth pushing guide moving guide frame 4, the thrust transmitted from the front driving part 31 to the front end bed plate through the hinge 7 is gradually reduced along with the relative transmission of the hinge 7, and the pressure applied to the output end of the driving part by the corresponding front end bed plate is smaller and smaller. However, when the front end top board is initially pushed to move, it is naturally desirable that the force applied to the front end top board by the front actuator 31 is as large as possible, and when the front end top board is changed to the second state, it is desirable that the resistance applied to the actuator by the front end top board is as small as possible.

For this reason, this application relies on the articulated frame of rotational design, just when the leading driving piece 31 begins to promote leading truck 4, first angle is little, and then the strength that the leading driving piece 31 can transmit the front end bed board is just big, and when leading truck 4 removed to the second position, the second angle is big, and then under the strength that the leading driving piece 31 can transmit the front end bed board, corresponding front end bed board transmitted the strength of leading driving piece 31 also little, so when the user leaned on the front end bed board, the pressure that the required bearing of leading driving piece 31 was just little.

Further, the first angle is defined as α ₁ ，0°≤α ₁ ≤10°。

The second angle is defined as alpha ₂ ，60°≤α ₂ Not more than 90 degrees; in this way, at a minimum value of 60 ° for the second angle, it can be ensured that the hinge 7 has a sufficiently large inclination angle when supporting the front end deck, 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 guide rods 12 arranged along the length direction of the bed frame 1, the guide frame 4 is slidably provided on the guide rods 12, and specifically, the guide frame 4 comprises a guide shell 41 and a connecting rod 42. The number of the guide rods 12 is two, the number of the guide shells 41 is also two, the two guide shells 41 are sleeved on the guide rods 12 to form sliding connection with the guide rods 12, and the head end and the tail end of each guide rod 12 are respectively connected to the two guide shells 41. In this way, the guide frame 4 can slide along the longitudinal direction of the frame 1.

Referring to fig. 1 and 3, the hinge member 7 includes a connecting bar 71, a rotating rod 72, and a hinge rod 73, wherein the connecting bar 71 is fixedly connected to the first front bed plate 22, and the head and the tail ends of the rotating rod 72 are rotatably connected to the connecting bar 71 and the guide shell 41, respectively. In this way, 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 is rotatably connected with the second front bed plate 23. The front driving member 31 is fixedly connected to the bed frame 1, in the present 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, in the present application, the guide shell 41 is slidably disposed on the guide rod 12, so that when the first front bed board 21 and the second front bed board 22 are turned to the backrest state, most of the pressure of the user leaning on the second front bed board will be changed to the pressure pressing on the guide rod 12, and only a small amount of force needs to be borne by the front driving member 31, so that in actual use, the requirement for the front driving member 31 is low.

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 in this way, when the front driving piece 31 retracts, the moving speed of the guide frame 4 is slow, and because of the friction force between the guide frame 4 and the guide rod 12, the safety is higher.

In the related design, the front driving member 31 can easily avoid the above problem compared with the design in which the backrest directly contacts.

As such, the present application has two states:

the bed state is as follows: in this state, the spread angle of the first front bed plate 22 and the middle bed plate 21 is a straight angle, the first front bed plate 22 is arranged along the length direction of the guide rod 12, while the spread angle of the second front bed plate 23 and the first front bed plate 22 is a straight angle, the second front bed plate 23 is arranged along the length direction of the guide rod 12; at this time, the guide frame 4 moves toward a side close to the front driving part 31, and the driving part ejector rod of the front driving part 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 tiled 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 therefore, the positioning can be performed smoothly in this state.

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

In summary, as for the above-mentioned working process, the first front bed board 22 and the middle bed board 21 are set to rotate, so that when the first front bed board 22 is flipped over a part of distance by an external force, the front driving member 31 will push the guide frame 4 to move, and further push the first front bed board 22 to flip up, thereby being very convenient when transferring 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 continuity of the whole device can be better, and the turning setting of a plurality of bed plates can be completed under the condition that only one linear driver needs to be provided.

Furthermore, the bed frame 1 is further provided with a supporting block 11, the supporting block 11 can support the first front bed board 22 and the second front board 23, the supporting block 11 is fixedly connected to the bed frame 1,

furthermore, in the practical use process, the back rest is only folded upwards in the sofa state, and the sofa is not suitable for the practical life. In the present application, the first rear bed board 24 and the second rear bed board 25 are also bent into a wave shape, so that when a user uses the sofa-like bed, the first rear bed board 24 and the second rear bed board 25 are arranged in a wave shape, and the shanks and thighs of the user can be supported by the first rear bed board 24 and the second rear bed board 25 when the user bends.

Specifically, first back bed board 24 and middle bed board 21 rotate to be connected, and second back bed board 25 rotates with first back bed board 24 to bed board 25's centre is changeed and is connected connecting rod 6 behind the second, and connecting rod 6 and bedstead 1 are for rotating the connection, and back driving piece 32 rotates and connects on bedstead 1, and the axle of kick-backing of back driving piece 32 constitutes to rotate the connection with first back bed board 24.

In this way, in the bed state, the first rear bed plate 24 and the second rear bed plate 25 are at a flat angle, the rebounding 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 tiled structure, so that the rebounding shaft of the driving member cannot move without external force. When needs use for the sofa state, only need stir down at the lower extreme of second back bed board 25 from last, just can let second back bed board 25 turn down, first back bed board 24 will stick up simultaneously, so the resilience axle of back driving piece 32 will continuously promote second back bed board 25 and turn.

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