BACKGROUND

This disclosure relates to the technical field of electric beds, in particular to an electric rocking bed.

Nowadays, there are many kinds of electric beds, and the parts of the conventional electric bed frame are relatively fixed. In order to improve the comfort and help people to fall asleep easily, it is necessary to improve the electric bed, especially to redesign the bed frame, so that the bed frame may rock from head to tail at a comfortable range. In addition, although there are also rocking electric beds at present market, their structural setting is unreasonable. The position of the support point is set at the central point of the bed. In fact, the position that people lay on the bed is not fixed. People also turn over and move during sleep. When the gravity of the human body deviates from the central point of the bed, the load of the motor and the operation of the machinery will change simultaneously, and such load difference results in the noise and friction sound of the motor and mechanical parts. Therefore, what is needed is an electric rocking bed with a more stable structure, which can contribute to a fast deep sleep and alleviate mechanical noise as well.

The electric rocking bed described herein makes the thrust of the head and tail of the bed swing evenly through the specially designed driving parts, reduces the impact on the motor and mechanical parts due to the movement of the human body on the bed, and minimizes the noise of the motor and mechanical parts caused by the change of load.

As can be seen inFIG.5and the enlarged view inFIG.7, in preferred embodiments the driving part500includes a rotating motor510fixed on the base100, the rotating motor510is connected with a reducer520, and the reducer520is also connected with a transmission gear530. The base100is provided with a rotating shaft600, and the rotating shaft600is provided with a driven gear610connected with the transmission gear530through a synchronous belt540. The rotating shaft600is connected with one end of a first rotating arm620, and the other end of the first rotating arm620is connected with one end of a second rotating arm630. The other end of the second rotating arm630is rotationally connected with the bed frame200, as inFIG.5. Specifically, one end of the first rotating arm620is provided with a connecting hole for the rotating shaft600to penetrate into the fixed connection, the other end of the first rotating arm620is provided with a circular hole, and one end of the second rotating arm630is provided with a through-hole corresponding to the circular hole. Between the other end of the first rotating arm620and one end of the second rotating arm630, a pin penetrates the circular hole and the through-hole to form a rotating connection. The other end of the second rotating arm630is rotationally connected with the bed frame200through an articulated manner. The electric rocking bed eliminates the click and friction sound caused by the reducer gap through precisely setting the matching parameters of the rotating motor510and the reducer520.

Both ends of the rotating shaft600are respectively connected with a bearing assembly700on the base100. One end of the rotating shaft600extends out of the bearing assembly700and is connected with one end of the first rotating arm620. There may be two bearing assemblies700. The two bearing assemblies are matched with both ends of the rotating shaft600, where one end of the rotating shaft600is matched with a bearing assembly700, and the other end of the rotating shaft600extends out of the other bearing assembly700through the driven gear610and is connected with one end of the first rotating arm620. This bearing assembly can be constructed according to known principles.

As shown inFIGS.5and7, there is a motor mounting base110on the base100. Both sides of the motor mounting base110are respectively provided with a connecting frame120connected with the base100. One end of the two connecting frames is connected with the base100through the connecting assembly1, and the other end of the two connecting frames is connected with the horizontal rail130connected to the base100through the connecting assembly1. Both sides of the motor mounting base110are detachably connected with the connecting frame120through the connecting assembly1, and two bearing assemblies are placed on the two connecting frames. The connecting assembly1is a bolt and a flat nut.

As seen inFIGS.8and9, during operation, when the rotating motor510of the driving part500drives the reducer520to work, the reducer520drives the transmission gear530to rotate, and then drives the driven gear610connected with the transmission gear530through the synchronous belt540to move, and the driven gear610drives the rotating shaft600to move, and then drives the first rotating arm620connected with the rotating shaft600to rotate, When the first rotating arm620rotates, it drives the second rotating arm630to rotate, and then drives the bed frame200connected with the second rotating arm630to move. At the same time, the movement of the bed frame200drives the swinging part400to move synchronously, so that the bed frame200can rock from head to tail.

Accordingly, preferred embodiments disclosed herein relate to an electric rocking bed that comprises a base, a bed frame positioned above the base, on which a mattress may be placed, at least two swing parts connected to the base and to the bed frame, where the swing parts comprise movable connections and are connected to the bed frame through the movable connections, and a drive part. The bed frame moves relative to the base through movement of the movable connection of the swing parts. The drive part, which is electrically driven, drives the motion of the bed frame relative to the base in a rocking motion. The bed frame may be fixedly or detachedly connected to the base.

In preferred embodiments the bed frame has a top portion and a bottom portion. The top portion is where the mattress would be placed. The bottom of the bed frame may comprise bed frame struts. The swing parts may comprise support frames and swing arms, which serve as the movable connections of the swing parts. The swing arms are rotationally connected to the support frames, which are connected to the base, and the bed frame struts are rotationally connected to the swing arms. In additional embodiments each swing part may comprise one support frame and two swing arms. In further preferred embodiments, the electric rocking bed has a left side and a right side, and two swing parts. Each swing part is preferably positioned centrally or close to the middle of each side of the bed frame, one on the right side and one on the left side. The bed frame of the electric rocking bed may also have two ends, where a sleeper might position his or her head or feet, in addition to the left side and right side. In further preferred embodiments, the drive part of the electric bed connects to the bed frame closer to an end of the bed frame than a central position on the bed frame. The positioning of the drive part, which is connected to the bed frame closer to an end of the bed frame, and the swing parts, connected to the bed frame centrally on sides of the bed frame, sets the fulcrum of the bed on both sides on the middle of the base. This reduces the impact on the motor and mechanical parts due to the posture change of the human body on the bed, ensures structural stability, and reduces stress.

In preferred embodiments the drive part comprises a rotating motor, a reducer, a transmission gear, a rotating shaft, which also comprises a driven gear, a synchronous belt, and a first and second rotating arm. The rotating motor is attached to the base and also to the reducer. The reducer connects to the transmission gear. The synchronous belt runs between and connects the transmission gear to the driven gear of the rotating shaft. The rotating shaft is connected with a first end of the first rotating arm through a pivotal connection. On the other end of the first rotating arm, the first rotating arm is connected to the second rotating arm through a pivotal connection. The other, second end of the second rotating arm is connected to the bed frame through a rotational connection. The rotating motor is electrically driven and, when engaged, engages the reducer, which causes rotation of the transmission gear. The synchronous belt then causes rotation of the rotating shaft. Rotation of the rotating shaft causes movement of the first and second rotating arms, which move the bed frame relative to the base in a rocking motion. The drive part may further comprise bearing assemblies. The rotating shaft may be connected to the bearing assemblies on each end, and one end of the rotating shaft extends out of one of the bearing assemblies to connect with the first end of the first rotating arm. The electric rocking bed may also comprise a motor mounting base, and where the rotating motor is attached to the motor mounting base.
