Problems solved by technology
There are certain defects in this connection method. Since the bed board is mostly made of wood and its characteristics are relatively soft, the stress points of the drive rod are concentrated on the bed board when the bed board is raised and lowered. It affects the service life of the electric bed; in addition, due to the space limitation of the general electric bed, the force arm of the bed plate on the back of the front motor drive head is short, and the load carried by the front motor is relatively large, which may easily cause the front motor to be overloaded and damaged, or choose a larger load The motor increases the production cost of the electric bed

Embodiment Construction
[0020] Such as Figure 1 to Figure 4 As shown, the front motor drive structure of the electric bed of the present invention includes a head back bed board 1 and a fixed bed board 2, an upper frame 3, a lower frame 4, and a front motor 5 with a driving rod 51 that are hinged to each other. The upper frame 3 It includes two side rods 31, two cross rods 32 and four guide mechanisms 33. The two side rods 31 are arranged in parallel and spaced apart and both ends are bent and warped. The two cross rods 32 are spaced in parallel to the Between the two side bars 31, the four guide mechanisms 33 are respectively arranged at both ends of the two side bars 31, and the two cross bars 32 are provided on the bottom surface of the fixed bed board 2, and the upper frame 3 One end extends below the head back bed board 1; the lower frame 4 includes a rectangular frame 41, a middle connecting rod 42, a first ear pan 44 and four short guide rails 43. The middle connecting rod 42 is horizontally a...

The invention discloses a front motor driving structure of an electric bed. In the driving structure, the bed board on the head and back is hinged to the fixed bed board, the upper frame is arranged on the bottom surface of the fixed bed board, the upper and lower frames are movably connected through a guide mechanism and a guide rail, and the lower frame is provided with an intermediate connection. Rod, the middle connecting rod is provided with the first ear climber, the rotating rod of the front motor bracket is hinged between the two side rods at one end of the upper frame, the two connecting rods are set on the rotating rod, and the second ear climbing is set on the rotating rod Bottom surface; the bottom edge, two sides and two bases of the linear bearing assembly are respectively arranged on the bottom surface of the bed board on the back of the head, and the two linear bearings are connected to the bottom edge and the two bases, and the two connecting rods of the front motor bracket are hinged to the two linear bearings ; The front motor is hinged with the first ear climber, and the driving rod of the front motor is hinged with the second ear climber. The drive structure overcomes the defects of the traditional electric bed front motor connection structure, avoids damage to the head, back bed board and front motor, improves the service life of the electric bed, and reduces the production cost of the electric bed.
Description
Technical field [0001] The invention relates to a front motor drive structure of an electric bed. Background technique [0002] With the improvement of people’s living standards, electric beds have been widely used; in general, electric bed boards are composed of multiple hinged bed boards, followed by head and back bed boards, fixed bed boards, leg bed boards, and foot bed boards. The frame and the lower frame movably connected with the upper frame respectively drive the bed board to realize lifting through the provided front and rear motors, so as to meet the needs of changing the posture of the human body lying on the bed. The front motor is used to drive the up and down of the bed on the back of the head. Generally, the base of the front motor is hinged on the middle connecting pipe of the lower frame. The driving rod of the front motor is directly hinged to the bottom of the bed on the back of the head through earclips. This connection method has certain defects. Since most...
