Fig. 2 is a schematic view of a folded state of the electric linkage chair frame according to the present embodiment.
Detailed Description
The motorized ganged chair frame of the present invention is further described with reference to fig. 1-2.
An electric linkage chair frame is characterized by comprising a positioning plate 3, a telescopic leg support 1, a connecting rod group 4, a seat 2 and a backrest 40. The locating plate is used for being fixed on the sofa frame. The telescopic leg support 1 is mounted on the front end part of the positioning plate 3, the lower end of the backrest 40 is pivoted on the rear end part of the positioning plate 3, and the upper end can swing. As shown in fig. 1, the link set 4 includes a first link 41 and a second link 42, where a first end, i.e., a front end, of the first link 41 is pivotally connected to one of the rod bodies in the telescopic leg support 1, a second end, i.e., a rear end, of the second link 42 is pivotally connected to a first end, i.e., a front end, of the second link 42, and a portion of the second link 42 near the second end is pivotally connected to a portion of the positioning plate 3 near the front end. The seat 2 has a supporting portion 21 protruding downward near the front end, the front end of the seat 2 is pivotally connected to the second end of the second link 42 via the supporting portion 21, and the rear end is pivotally connected to the middle of the backrest 40.
Specifically, the travel between the pivot point between the support portion and the second link 42 to the pivot point between the positioning plate 3 and the second link 42 is a forward swing radius 72, and the travel between the pivot point between the seat portion 2 and the backrest 40 to the pivot point between the backrest 40 and the positioning plate 3 is a backward swing radius 73, and the distance of the forward swing radius 72 is smaller than the distance of the backward swing radius 73. The included angles between the front swing radius 72 and the rear swing radius 73 and the horizontal plane are respectively a front included angle 71 and a rear included angle 74, and the front included angle 71 and the rear included angle 74 are gradually increased in the process of switching from the folded state to the unfolded state, and the front included angle 71 is increased from an acute angle to an obtuse angle, and the rear included angle 74 is always smaller than 90 degrees. Based on this structure, when the seat frame is switched from the folded position to the lying position, the seat 2 swings backward and the rear end of the seat 2 gradually descends relative to the front end to adjust the angle of the seat 2, thereby significantly improving the comfort of the user in the lying state.
In this embodiment, the telescopic leg support 1 has a specific structure that the telescopic leg support 1 includes a first rod 11, a second rod 12, a third rod 13, a fourth rod 14, and a leg rest group 15, in the unfolded state, the rear end of the first rod 11 is pivoted to the front end of the positioning plate 3, the front end is pivoted to the rear end of the second rod 12, the front end of the second rod 12 is pivoted to the leg rest group 15, the rear end of the third rod 13 is pivoted to a position of the positioning plate 3 near the front end, the front end is pivoted to the rear end of the fourth rod 14, the front end of the fourth rod 14 is pivoted to the leg rest group 15, and the first connecting rod 41 is pivoted to the third rod 13.
A tension spring 5 for providing a folding force for the telescopic leg support 1 is arranged between the third rod body 13 and the positioning plate 3. Namely, the third rod body and the positioning plate are provided with positioning pins, and two ends of the tension spring 5 are respectively hung on the two positioning pins. The folding of the invention can be facilitated by the structure.
The first connecting rod 41 is fixedly connected with a front motor tube connecting plate 61, and the positioning plate 3 is provided with a rear motor tube connecting plate 62. The push rod end of the push rod motor is connected with the front motor tube connecting plate 61 through a front motor tube, and the motor end of the push rod motor is connected with the rear motor tube connecting plate 62 through a rear motor tube, so as to drive the chair frame to be unfolded or folded.
When the swing type leg support is specifically used, the push rod motor drives the first connecting rod 41 to swing back and forth, when the first connecting rod 41 swings forward, the telescopic leg support 1 can be driven to be unfolded, meanwhile, the second connecting rod 42 drives the seat 2 to swing back, the upper end of the seat 2 linked backrest 40 swings back and forth, and finally, the lying state is formed. The distance between the seat part 2 and the leg rest group 15 can be increased after the seat part 2 swings backwards, so that the legs of a user can be supported conveniently, and the rear end of the seat part 2 gradually sinks relative to the front end in the backward swinging process of the seat part 2, so that the comfort of the lying state of the user is improved. When the electric push rod contracts to drive the first connecting rod to swing backwards, the process is reversed.
