Description

Technical Field

[0001] The utility model relates to the field of household manufacturing, and particularly relates to a double-drive flat-laying sofa functional iron frame. Background Art

[0002] The current sofa functional iron frame can realize the conversion among sitting position, TV position and lying position. The sitting position means that both the leg mechanism and the backrest mechanism are in the retracted state, the TV position is the state where the leg mechanism is unfolded, and the lying position is the state where both the leg mechanism and the backrest mechanism are unfolded. However, the backrest mechanism and the leg mechanism are related. When the backrest mechanism needs to be unfolded, the leg mechanism must be unfolded first. After the backrest mechanism is unfolded, the unfolding angle of the leg mechanism cannot be adjusted, which is difficult to meet the diverse usage requirements of users.

[0023] As Figures 1-5As shown, a dual-drive flat-lying sofa functional iron frame comprises a base 1, the base comprises two symmetrical side bottom bars 11, a front bottom bar 12 and a rear bottom bar 13 are fixedly connected between the two side bottom bars, the front and rear bottom bars and the two side bottom bars form a mouth shape, the front side of the side bottom bars is fixedly connected to the front supporting legs 2, the rear side of the side bottom bars is fixedly connected to the rear supporting legs 3, the tops of the front supporting legs and the rear supporting legs are fixedly connected to the assembly side panels 4, the front side of the assembly side panels is installed with a leg mechanism 5, the leg mechanism comprises a leg connecting rod 1 51 and a leg connecting rod 2 52 pivotally connected to the front side of the assembly side panels, the front end of the leg connecting rod 1 is pivotally connected to the leg connecting rod 3 53, the front end of the leg connecting rod 2 The leg connecting rod 4 54 is pivotally connected, the rear side of the leg connecting rod 4 is pivotally connected to the front side of the leg connecting rod 1, the front ends of the leg connecting rod 4 and the leg connecting rod 3 are pivotally connected to the footrest 55 at the same time, the backrest mechanism 6 is installed on the rear side of the assembly side panel, the backrest mechanism includes a backrest mounting plate 61 pivotally connected to the rear side of the assembly side panel, the backrest mounting plate is pivotally connected to the backrest support rod 62, the rear side of the assembly side panel is fixedly connected to the first limiting pin 41, the backrest support rod is provided with a first limiting surface 621 that cooperates with the first limiting pin, the first limiting surface abuts against the first limiting pin, limits the maximum flipping angle of the backrest mounting plate, prevents backward tilting, in order to avoid the convex bump on the assembly side panel, the front support The top of the leg is installed on the inner side of the assembly side panel, and the second limit pin 21 is installed on the upper side of the front supporting leg. The second limit pin abuts against the lower edge of the assembly side panel to increase the supporting force of the assembly side panel. The leg connecting rod 2 is provided with a second limit surface 521 that cooperates with the second limit pin. The second limit surface abuts against the second limit pin to prevent the leg mechanism from shrinking too tightly and getting stuck. It is also used to install the first wooden frame mounting plate 42 above the second limit pin on the front side of the assembly side panel. In order to avoid interference with the backrest support rod, the top of the rear supporting leg is installed on the outer side of the assembly side panel, and the top of the rear supporting leg is bent to form the second wooden frame mounting plate 31, so that The structure of the assembled side panels can be simplified and the cost can be reduced.

[0024] The specific working process and principle of this utility model:

[0025] When sitting, both the leg mechanism and the backrest mechanism are in a retracted state.

[0026] When in the TV posture, only the leg mechanism is opened separately, the first push rod motor is started, the telescopic rod of the first push rod motor is extended, and the first driving rod drives the leg mechanism to unfold.

[0027] When reclining, only the backrest mechanism is opened separately, and the second push rod motor is started. The telescopic rod of the second push rod motor retracts, and the second driving rod drives the backrest mechanism to unfold.

[0028] When lying flat (lying position), the first and second push rod motors can be started simultaneously to drive the leg mechanism and the backrest mechanism to unfold simultaneously.

[0029] The actions of the leg mechanism and the backrest mechanism of the present utility model are not related, and the opening and closing actions can be performed separately. Compared with the current sofa functional iron frame, the opening angle of the backrest mechanism is larger, and lying flat can be achieved, improving the comfort of users during use. Moreover, the angles of the backrest mounting plate and the footrest can be adjusted arbitrarily at any time, meeting the diverse usage needs of users.
