description of the reference symbols

The neck support comprises a rotating frame 1, a head plate 2, a back plate 3, a curved surface 4, an electric push rod 5, a roller 6, a support surface 7, a connecting rod 8, a rotating shaft 9, a headrest 10, a neck support air bag 11 and a cavity 12.

Detailed Description

The present invention will be described in further detail with reference to examples.

The existing electric bed frame comprises a bed body fixing frame, a rotating frame 1 is rotatably connected to the bed bottom fixing frame, a head plate 2, a back plate 3, a waist plate and the like are arranged on the rotating frame 1, and the rotating frame 1 can rotate under the action of an external mechanism to drive the head plate and the back plate on the rotating frame to synchronously rotate. The embodiment proposes a head plate assembly for an electric bed frame, which is an improvement on the existing electric bed frame, as shown in fig. 1, a back plate 3 is fixed on a rotating frame 1, and one end of a head plate 2 and a back plate 3 is rotatably connected with the rotating frame 1, as same as the prior art. The bottom surface department of head board 2 is equipped with bellied curved surface 4, three electric putter 5 to the head board 2 side is flexible is installed to the bottom surface of back board 3, and electric putter 5's flexible end is equipped with gyro wheel 6. When the electric push rod 5 is in a contracted state, the roller 6 is supported on the plane of the bottom surface of the head plate 2, when the electric push rod 5 is extended, the roller 6 travels on the curved surface 4 of the head plate 2, and because the head plate 2 is rotatably connected with the rotating frame 1, the roller 6 can generate an upward force in the traveling process, so that the head plate 2 is turned upwards, and the head plate 2 is independently turned upwards relative to the back plate 3, as shown in fig. 2.

When the head plate 2 is turned up, the support of the head plate 2 is obtained from the rollers 6 and the rotation connection points with the rotating frame 1, and the support of the head plate 2 is stable because the rollers 6 and the rotation connection points are respectively positioned at the two ends of the head plate 2. When the head plate 2 is not turned up, the head plate 2 obtains support from the connection point with the roller 6 and the rotation, but since the roller 6 is close to the rotation connection point at this time, the support of the head plate 2 is unstable at this time. This drawback is not solved, as shown in fig. 4, the supporting surfaces 7 for being lapped on the rotating frame 1 are left on the two sides of the convex curved surface 4 on the bottom surface of the head plate 2 of the present embodiment, and when the head plate 2 is not turned over, the supporting surfaces 7 on the two sides are mainly used for supporting on the rotating frame 1.

As shown in fig. 3, in order to ensure the synchronism of the extension and retraction of the electric push rods 5, the fixed ends of two adjacent electric push rods 5 are connected through a connecting rod 8, and the rollers 6 on the plurality of electric push rods 5 adopt the same rotating shaft 9.

As shown in fig. 5, a head plate 2 is provided with a headrest 10, one end of a backrest plate 3 of the headrest 10 is provided with a neck support airbag 11, a cavity 12 is formed in the head plate 2, and a controller and a micro air pump for inflating the neck support airbag 11 are installed in the cavity 12 (the headrest 10 is not shown on the head plate 2 of fig. 1 and 2). The provision of the curved surface 4 increases the thickness of the head plate 2, which facilitates the provision of a cavity 12 in the head plate 2 for installation of the controller and the micro-pump. After the head plate 2 is turned over, the gap between the neck of the human body and the headrest 10 is increased, but since the neck support airbag 11 is provided, the gap can be filled by adjusting the size of the airbag, and the comfort of the neck is improved. In addition, in the present embodiment, the sound insulation material is filled in the cavity 12 of the head plate 2 to reduce noise caused by the operation of the micro air pump.

The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
