In particular, as shown in fig. 6-8, three position diagrams of the seat linkage support structure are shown, and in practical application, the driving mechanism can be controlled by a remote controller or a switch button to drive the seat linkage support structure to adjust the positions of the seat linkage support structure in sitting, extending and lying postures. When the seat is adjusted from a sitting posture to an extending posture, the push rod of the driving mechanism pushes the driving cross rod forwards, the driving cross rod drives the pedal telescopic mechanism 5 to extend forwards, and the linkage assembly and the backrest mounting piece are fixed. When the seat is adjusted from the stretching position to the lying position, the driving mechanism continues to operate the push rod to extend completely, the driving cross rod 7 and the pedal telescopic mechanism 5 are pushed to extend upwards, the seat frame 3 is driven to rotate upwards, the first elastic piece is tensioned, and the backrest mounting piece rotates downwards and backwards. When the seat frame is adjusted and retracted from the lying position, the seat frame is rotated and retracted downwards under the action of the elastic restoring force of the second elastic piece and the self gravity of a human body because the head is lifted and the upper body is erected at first when the seat frame is sat up, so that the backrest mounting piece 4 is rotated and retracted first, and then the pedal telescopic mechanism 5 is retracted. In the lying position, the first elastic member tightens the pedal telescoping mechanism, so the backrest mounting member is retracted first, and then the pedal telescoping mechanism is retracted. The first elastic piece and the second elastic piece with elasticity in the process can enable the seat support to be smooth in the position adjusting process, and meanwhile, the second elastic piece guarantees the movement sequence of the backrest mounting piece and the pedal telescopic mechanism in the process of unfolding and retracting the seat.
Specifically, as shown in fig. 9, the seat linkage support structure of the present invention is fixed in the armrest frames at both sides of the seat, and is fabricated into a sofa or a leisure seat by installing the armrest frame 200, the backrest frame 400 and the seat frame and then soft-packing the upholstery. It should be noted that, in this embodiment, the assembly plates are respectively connected to the two side armrest frames and are fixed, and the backrest frame 400 may be configured as a T-shaped frame when viewed from the front of the seat, so that two protruding ends of the T-shaped backrest frame do not interfere with the left and right armrest frames, and the T-shaped backrest frame 400 may rotate around the armrest frames.
As shown in fig. 10, the seat linkage support structure according to the embodiment of the present invention reduces the link member 8 compared with the prior art, and one end of the link member 8 is connected to the driving link and the other end is connected to the supporting portion. In the prior art, the seat support structure needs to be driven by a pedal telescopic mechanism and a backrest mechanism respectively through double motors, and the support structure only needs to be driven by a single motor through controlling and adjusting sequences by the motors.
As shown in FIG. 11, the inventive seat support has fewer parts of the linkage assembly than the original seat support, the backrest assembly is optimized to have only one backrest mount, and the seat support has a significantly reduced height, such as a height dimension compression of greater than 2cm.
The invention has the advantages of less parts, simple structure and small occupied space, and compresses the whole height of the bracket structure, so that the seat height is reduced, and the comfort level of the seat is improved.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are in no way limiting of the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
