Referring to fig. 1 and 2, the present application provides an embodiment of an electric bed, including:

the bed comprises a bed main body 1, a power-assisted mechanism 2, a first force sensor 3, a processor (not shown in the figure, can be arranged at any position of the electric bed, but can be in signal connection with the first force sensor and the power mechanism) and a power mechanism 4;

the bed main body comprises a first bed board 5 and a second bed board 6 which are positioned on the same plane;

As described above, the electric bed of the present embodiment is a bed that can electrically drive the bed board around the rotating shaft, and is suitable for daily living, especially for people with inconvenience in living, for example, the electric bed is used as a hospital bed for patients, and the power source may be mains power or a battery. The bed main body comprises a first bed board and a second bed board, when a person lies on the bed, the upper half body of the person can be placed on the first bed board, the lower half body of the person can be placed on the second bed board, or the upper half body of the person can be placed on the first bed board, and the lower half body of the person can be placed on the second bed board. At least one of the first bed board and the second bed board is provided with a rotating shaft, and the rotating shaft is parallel to the boundary line of the first bed board and the second bed board, or the rotating shaft is superposed with the boundary line.

The power-assisted mechanism refers to a mechanism which can provide power assistance for a user when the user gets up or lies down, and comprises a mechanism which is provided with a holding part and can provide the power assistance for the user, wherein the power-assisted mechanism comprises a bed edge handrail, or the power-assisted mechanism comprises a support rod 9 and a pull ring 10, and the pull ring is connected with the bed main body through the support rod. Wherein the bed edge armrest is arranged at the bed side (fig. 2, 4) in any way, such as detachably, foldably, fixedly connected, etc., and the bed edge armrest can be in any shape suitable for hand holding, such as U-shaped, such as straight rod-shaped, such as circular, etc., and the bed edge armrest comprises a handle 13, a connecting rod 14 and a force sensor 3, as shown in fig. 4, for example.

The support rod can be in any shape, such as a J shape, an L shape, a straight rod shape and the like, and the connection mode of the pull ring and the support rod can be any mode, such as a soft connection (such as a cable connection), an elastic connection and a hard connection, wherein the soft connection means that the support rod can only receive the pulling force of the pull ring and can not receive the pushing force (pressure) of the pull ring; the hard connection means that the support rod can be subjected to the pulling force of the pull ring and also can be subjected to the pushing force (pressure) of the pull ring.

As shown in fig. 3, the support rod is connected with the bed body, the bed body provides a supporting force, and the pull ring is connected with the support rod, wherein the height of the pull ring can be higher than the bed body to provide a pulling use for a user, and can also be lower than the bed body to provide a user to extend a hand below the bed body to hold the pull ring to pull the user. The first force sensor is arranged on the power-assisted mechanism, specifically, the first force sensor can be arranged on a handle part of the power-assisted mechanism, and can also be arranged on a supporting part of the power-assisted mechanism, so that the pushing force or the pulling force applied to the power-assisted mechanism can be sensed.

As shown in fig. 3, when the power assisting mechanism comprises a support rod and a pull ring, and the pull ring is connected with the bed body through the support rod, when a force sensor arranged on the power assisting mechanism senses a force signal (a pull signal is sensed by the pull ring, or a push signal is sensed by the pull ring when the pull ring is arranged on a support rod part which is not in the same axis with the pull ring, or a pull signal is sensed by the pull ring when the pull ring is arranged on a support rod part which is in the same axis with the pull ring), it indicates that the user intends to get up. The reason is that: the user intends to get up, pulls the pull ring, and therefore the pull ring receives pulling force, and the bracing piece position coaxial with the pull ring receives pulling force, and the bracing piece position not coaxial with the pull ring receives thrust, but no matter force sensor sets up on the pull ring or on the bracing piece, all can experience force signal. The force sensor can be arranged on the pull ring only, the support rod only or on both the pull ring and the support rod. The force sensor converts the sensed force into an electrical signal, and the force signal is an electrical signal obtained by converting the sensed force, namely the force signal is an electrical signal reflecting force information.

The processor may be any processor, such as a microprocessor MCU, a single chip microcomputer, or a processor that only transfers signals, that is, only transfers signals of the force sensor to the power mechanism, and the power mechanism controls the bed plate to rotate according to the signals (for example, the power mechanism includes a motor, electric signals corresponding to force signals in opposite directions fed back by the first force sensor are different (or opposite), and the motor rotates forward or backward according to the electric signals, thereby driving the bed plate to rotate). The processor is used for receiving a force signal sensed and sent by the first force sensor and controlling the bed board to rotate according to the force signal, and the rotation can change the first bed board and the second bed board from a parallel state to a certain inclination angle and also change the first bed board and the second bed board from the state of the certain inclination angle to the parallel state. The power mechanism includes a motor 11 and a mechanical force conducting structure (e.g., an expansion link (i.e., an electric push rod) 12), the motor is, for example, a step motor, and when receiving a signal sent by the processor, the motor can drive the first bed board or the second bed board to rotate.

Furthermore, at least one of the first bed board and the second bed board can be provided with a rotating shaft 7; the rotating shaft is parallel to a boundary line 8 between the first bed board and the second bed board, or the rotating shaft is superposed with the boundary line; the power mechanism is configured to drive the first bed board or the second bed board to rotate after receiving a signal sent by the processor.

Further, the height of the supporting rod is adjustable. Specifically, the support rod is telescopically and fixedly connected with the bed main body, and when the height of the support rod needs to be adjusted, the support rod can be extended or shortened firstly, and then the support rod is fixed with the bed main body.

Furthermore, the power mechanism drives the first bed board and/or the second bed board to rotate, wherein the rotating speed is in direct proportion to the pulling force sensed by the first force sensor.

In one embodiment, the power assisting mechanism comprises a support rod and a pull ring, the pull ring is connected with the bed main body through the support rod, a second force sensor is arranged on the bed plate with the rotating shaft, and the second force sensor is in signal connection with the processor. The processor passes through the second force sensor can more accurately distinguish user's intention and be getting up or lying down to after receiving first force sensor's signal, the rethread second force sensor differentiates user's intention and is getting up or lie down, control power mechanism drives in view of the above first bed board or the second bed board makes corresponding rotation. Specifically, when the user intends to get up, the user does not have pressure on the bed plate, otherwise, the user intention can be judged by pressing the bed plate, so that the bed plate is correspondingly driven to tilt or be laid flat.

In one embodiment, the first bed board has a first rotating shaft, the second bed board has a second rotating shaft, the power mechanism drives the first bed board to rotate around the first rotating shaft, and the power mechanism drives the second bed board to rotate around the second rotating shaft, so that the first bed board and the second bed board can rotate simultaneously when needed. After receiving the signal sent by the processor, the power mechanism can drive the first bed board to rotate around the first rotating shaft, and simultaneously drive the second bed board to rotate around the second rotating shaft. When a user has a particular need, for example, a leg of the user is injured, the user wants to relax his body in a state where the lower body is slightly raised and the upper body is also slightly raised. The purpose can be achieved by driving the first and second turning shafts simultaneously.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application, or which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
