Detailed Description

The chassis structure of the motor-driven rotary sofa of the present invention will be further described with reference to fig. 1 to 2.

The utility model provides a motor drive formula sofa chassis structure that rotates, includes chassis 1 and sets up carousel group 2 on chassis 1, characterized by: the turntable group 2 comprises a lower turntable 21 mounted on the base frame 1 by bolts and an upper turntable 22 rotatably mounted on the lower turntable 21. A driving motor 3 for driving the upper turntable 22 to rotate relative to the lower turntable 21 is arranged between the upper turntable 22 and the underframe 1.

As a preferred embodiment of the driving motor, the driving motor 3 is a push rod motor, a motor end of the push rod motor is connected to the bottom frame 1 through a connecting plate 31, and a push rod end of the push rod motor is connected to the upper rotary table 22 through a U-shaped seat 32. Namely, the motor end of the push rod motor is pivoted with a connecting plate 31, and the connecting plate 31 is fixed on the underframe 1 through bolts; the push rod end of the push rod motor is pivoted with a U-shaped seat 32, and the U-shaped seat 32 is fixed on the upper turntable 22 through a bolt. Therefore, the extension and contraction of the push rod motor can drive the upper turntable 22 to rotate relative to the lower turntable 21.

In a preferred embodiment of the rotation of the upper rotating disk relative to the lower rotating disk, the upper rotating disk 22 and the lower rotating disk 21 are respectively provided with an upper ring groove 222 and a lower ring groove 211, the upper ring groove 222 and the lower ring groove 211 are correspondingly formed into ball grooves, and balls are arranged in the ball grooves, so that the upper rotating disk 22 can stably rotate relative to the lower rotating disk 21.

In use, in order to limit the upper rotor disc from rotating freely, the lower rotor disc 21 is provided with two lower convex limiting blocks 212, and the upper rotor disc 22 is provided with an upper limiting block which is convex downwards and is positioned between the two lower limiting blocks 212. When the upper rotary table 22 rotates, the two lower limit blocks 212 are positioned on the rotation line of the upper limit block, and block the upper limit block, thereby limiting the rotation range of the upper rotary table 22. The lower limit block 212 may be set according to the actual rotation angle of the upper dial 22 when specifically set.

Two mounting rods 221 for mounting the sofa iron frame are mounted on the upper rotary table 22 through bolts, and the U-shaped seat is also fixed on the side surface of the mounting rod 221.

Based on under the above-mentioned structure, can drive through driving motor 3 flexible the carousel 22 for carousel 21 and chassis 1's positive and negative rotation down, showing the convenience that has promoted the sofa rotation, convenient to use person's use.

Unless otherwise specified, in the present invention, if there is an orientation or positional relationship indicated by terms of "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., based on the orientation or positional relationship shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, rather than to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, the terms describing orientation or positional relationship in the present invention are for illustrative purposes only, and should not be construed as limiting the present patent, specific meanings of the above terms can be understood by those of ordinary skill in the art in light of the specific circumstances in conjunction with the accompanying drawings.

Unless expressly stated or limited otherwise, the terms "disposed," "connected," and "connected" are used broadly and encompass, for example, being fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
