Embodiment 1

[0041] Such as figure 1 As shown, a mechanical stretching device is used in a mechanical stretching device for moving seat or functional sofas, the mechanical stretching device including a seat frame support mechanism 1, suspended translation mechanism 2, back stretch mechanism 3, leg stretch mechanism 4 and The drive device 5, the suspension translation mechanism 2 is symmetrically disposed on both sides of the seat frame support mechanism 1 and is rotatable with the seat frame support mechanism 1, and the back extension mechanism 3 is located at the rear of the seat frame support mechanism 1 and the housing translation mechanism 2 can be Turn the connection, the leg stretching mechanism 4 is located at the front portion of the seat frame support mechanism 1 and rotatably couples with the seat frame support mechanism 1, and the driving device 5 is connected to the suspension translation mechanism 2, wherein the drive device 5 is driven. Including the motor 52 and the drive rod 51...

Embodiment 2

[0043] Embodiment 2 is a specific manner based on Embodiment 1.

[0044] Such as figure 2 As shown, the seat frame support mechanism 1 includes a two-petal symmetric dispatch base 11, the suspension translation mechanism 2 rotates to the seat plate mounting base 11, and the suspension translation mechanism 2 also includes two petals The side beam 201 connected to the base 11 is connected, and the two cross beams 201 are respectively connected to the leg stretching mechanism 4, the back stretch mechanism 3, and the drive device 5, respectively. The beam 201 is rotated by the conveying mechanism 2, the leg stretching mechanism 4, and the drive rod 52 in the drive unit, and the other beam 201 rotates the connection with the back stretch mechanism 3 by the adapter sheet.

[0045] In the above configuration, the leg stretch mechanism 4, the suspension translation mechanism 2, and the back extension mechanism 3 are subjected to the link, thereby implementing the implementation of the mo...

Embodiment 3

[0047] Embodiment 3 is a specific manner of embodiment 2, in Example 2.

[0048] Such as image 3 As shown, the back stretching mechanism 3 refers to a link assembly having a substantial relationship and rotatably coupled to each other, and at least one of the linkages is rotated from the suspended translation mechanism 2; thus, when the suspension When the translation mechanism 2 occurs, the back stretching mechanism 3 is also a corresponding posture transition.

Abstract

The invention relates to a mechanical stretching device for a movable seat or a functional sofa. The device comprises a suspension translation mechanism (2), a back stretching mechanism (3), a leg stretching mechanism (4), a seat frame supporting mechanism (1) and a driving device (5); the suspension translation mechanism (2) comprises two parallelogram-like mechanisms which are connected with each other, the two parallelogram-like mechanisms act in sequence, and the motion trails of the two parallelogram-like mechanisms are parallel to each other or are located on the same axis, so that the purpose of translation action is achieved, and a mutual restraining structure is arranged between the suspension translation mechanism (2) and the back stretching mechanism (3); therefore, when the back stretching mechanism (3) inclines, the space after inclination is not increased. The suspension translation mechanism and the back stretching mechanism of the mechanical stretching device are more compact and flexible, and meanwhile, the height of the suspension translation mechanism is reduced, so that even if the height of the cushion is reduced, the spacing distance between the sofa and the ground is not influenced.

Description

Technical field [0001] The present invention is a mechanical stretching device for moving seat or functional sofa; it involves the design, manufacturing of a movable seat or functional sofa or deformable sofa; this mechanical stretching device is specifically improved functionality. The degree of coordination of the skeleton of the sofa, smoothness and further improved the rationality of its structure. Background technique [0002] For event seat or functional sofa, this facility is usually at least a set of link mechanical stretching devices that enable active seat or functional sofa to change the gesture (also known as skeleton or iron frame); It includes a flexible coating wrapped outside the mechanical stretching device. Among them, the mechanical stretching device is divided according to its support site of the human body, at least the frame support mechanism, a back extension mechanism (or a backrest mechanism) and a leg stretching mechanism; additionally, a hovering transl...
