Electric bed front motor drive structure

摘要

The invention discloses an electric bed front motor drive structure. The structure of the drive head back bed board is connected to the fixed bed board. The top frame is set beneath the fixed bed board. The upper and lower frame are connected by guiding mechanism and rail movements. The bottom bedframe has intermediate connecting rods. The intermediate connecting rod has a first bracket. The rotation of the motor bracket lever is hinged at one end of the upper frame between the two side rods. Two connecting rods is set on the rotating rod. Second bracket is located underneath the motor bracket lever. The linear bearing assembly's bottom edge, two sides and two bases are located at the head back portion of the bed board underside. The two linear bearing assemblies connect the bottom edge and two bases.

主权项

1. An electric bed front motor drive structure comprising:
a. head back bedboard in hinged connection to a middle bedboard, wherein the middle bedboard is attached to and supported by an upper frame, wherein the upper frame is attached to and supported by a lower frame, wherein the head back bedboard is configured to hinge upward for raising a head of a user; b. wherein the lower frame has a pair of connecting rods extending toward the head back bedboard; c. a linear bearing assembly having edge members attached to linear bearings, wherein the linear bearing assembly is attached to the head back bedboard to support the head back bedboard, wherein the linear bearing assembly is hinged to the pair of connecting rods in a sliding configuration; d. a front motor mounted to the lower frame at a first end of the front motor, and hinge mounted to a front motor frame at a second end of the front motor, wherein the front motor is configured to push up the head back bedboard when the front motor has a drive rod that extends to travel from a retracted position to an extended position, wherein during front motor operation, the head back bedboard has supplemental support from the pair of connecting rods, wherein the linear bearings assemblies are mounted under the head back bedboard and are actuated by the front motor so that they slide when raising and lowering the head back bedboard.
