Detailed Description
The electric backrest structure convenient to install of the present invention is further described with reference to fig. 1 to 2.
The utility model provides an electronic back structure convenient to installation, characterized by: comprises a backrest frame 4, a backrest frame 1 and a driving assembly 5. The backrest frame 1 is hinged to the top of the backrest frame 4, so that the backrest frame 1 can rotate back and forth relative to the backrest frame 4. The driving assembly 5 is mounted on the backrest frame 4 and is connected with the headrest frame 1, so that the headrest frame 1 can be supported, and the headrest frame 1 can be driven to swing back and forth relative to the backrest frame 4. The lower side position of the backrest frame 4 is connected with two connecting plates 6 in a bolt connection or welding mode, the connecting plates 6 are provided with slots 61, and the backrest frame 4 is inserted on the sofa seat 10 through the slots 61 on the connecting plates 6.
Specifically, the structure of the headrest frame 1 and the backrest frame 4 comprises a cross bar 12/41 and two side bars 11/42 at two ends of the cross bar 12/41, a first connecting piece 2 is fixed on each side bar 11 of the headrest frame 1 through a screw, a second connecting piece 3 is fixed on each side bar 42 of the backrest frame 4 through a screw, and the lower end position of the first connecting piece 2 is hinged with the upper end position of the second connecting piece 3 through a hinge pin.
The second connecting piece 3 is inserted with a limit pin 31, and the first connecting piece 2 is provided with an arc-shaped limit groove 21 for matching the limit pin 31, so that the rotation angle of the backrest frame 1 relative to the backrest frame 4 is limited, and the backrest frame 4 rotates in a reasonable range. When the length of the arc-shaped limiting groove 21 is actually set, the setting can be performed according to the actually required swing angle of the head frame 1.
The driving component 5 is an electric push rod, the motor end of the electric push rod is hinged on the motor support 7 through a pin rod, the motor support 7 is welded on one side rod 42 of the backrest frame 4, and the push rod end of the electric push rod is hinged on the first connecting plate 2 which is relatively drunk through the pin rod.
A torsion spring 8 is arranged between the other first connecting piece 2 connected with the electric push rod and the corresponding second connecting piece 3. Namely, the pin rod for hinging the other first connecting piece 2 and the second connecting piece 3 is sleeved with a torsion spring 8, and two end parts 81 and 82 of the torsion spring 8 are respectively abutted against the first connecting piece 2 and the second connecting piece 3, so that an elastic limit structure is formed, and the problem of left-right shaking of the head frame 1 is avoided.
The insertion groove 61 is formed therein with a stopper piece 62 defining an insertion depth. When the corresponding component of the sofa 10 is inserted into the slot 61, it will abut against the position-limiting piece 62, so as to achieve the effect of stable insertion.
