Description

Technical Field

[0001] The utility model relates to the field of electric bed frame structures, in particular to a novel motor assembly structure for a bed. Background Art

[0002] Electric beds can electrically control the height of the head or foot of the bed board and freely adjust the bending degree of the bed board. They are divided into two categories: slat frame and bed board. Slat frame is called European electric bed, while bed board is called American electric bed. Depending on the needs, vibration or music functions may be configured. Nowadays, it can also be connected to mobile devices for remote control. It is generally used in homes or medical care.

[0003] Some structures of the electric bed have the function of lifting and lowering, which requires the push rod motor to drive and realize. The existing patent CN202022718497.4 provides a driving mechanism and an electric bed for an electric bed, including: a housing, a driving assembly placed in the housing, and a transmission frame connected to the swing arm on the electric bed. The transmission frame is hinged on the housing, and the driving assembly includes a driving member and a driving block connected to the driving member. The driving frame is hinged to the driving block, and the driving member drives the driving block to make a linear motion and then rotate the driving frame. The utility model is convenient for overall installation and disassembly, and there is no need to position and install each component in the driving assembly separately, which improves the assembly efficiency of the electric bed.

[0004] However, the above patent still has the following defects: the drive assembly is placed in the housing, which increases the time required for prefabricating the components of the drive mechanism in the housing, resulting in low production and processing efficiency;

This will inevitably lead to unstable movements when driving the head bed board, back bed board or leg bed board to move during actual practical use, affecting the user's experience.

The groove 11 is a rectangular groove, which is used to accommodate the rotation and rise of the rocker arm 3. The two sides of the width end are provided with mounting grooves 12. The mounting groove 12 is just enough to accommodate the L-shaped structure, which is used to just accommodate the linear drive component 2 installed from bottom to top in the square tube 1, and the square tube 1 and the motor cover 23 of the linear drive component 2 are threadedly connected.

[0040] A mounting hole is provided on both sides of the width of the square tube 1 below the groove 11 .

[0044] The driving slider 21 , the baffle plate 24 and the stabilizing block 25 are all arranged outside the motor cover 23 , which can further reduce the volume of the structure and make the structure more compact.

[0045] The driving motor 22 drives the driving slider 21 to move forward along the length direction of the square tube 1 toward the adjacent groove 11, thereby driving the adjacent driving part 33 to rotate and descend, and then the adjacent lifting part 31 rotates and rises. At the same time, the extended side of the lifting part 31 moves out of the inner cavity of the square tube 1 through the groove 11, or the driving motor 22 drives the driving slider 21 to retreat along the length direction of the square tube 1. Then, the lifting part 31 will rotate and descend under the action of the gravity of the bed board, and then the adjacent driving part 33 will rotate and rise.

[0051] The stabilizing block 25 is provided with a through slot for accommodating the sliding seat 26 to pass through, so that the stabilizing block 25 is slidably mounted on the sliding seat 26 .

[0052] A bearing is installed on both sides of the turbine 27 inside the motor cover 23 .

[0053] The motor cover 23 is a split T-shaped structure, including a first shell and a second shell. An extension portion is provided in the middle of one side of the first shell close to the second shell, and a first through hole penetrating the extension portion is opened on the first shell to accommodate the output end of the drive motor 22 to pass through.

The rocker arm 3 can be rotatably connected to the inner cavity of the square tube 1 near the groove 11 through the connecting portion 32, so that its driving portion 33 is arranged on the side away from the groove 11 near the driving slider 21, and the side of the driving portion 33 close to the driving slider 21 is arranged in an arc shape.

[0057] A plurality of inserting pieces 4 are further provided between the two rocker arms 3 , and the inserting pieces 4 have the same connecting portion 32 and driving portion 33 as the rocker arms 3 .
