Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Figures 1 to 3, a dual-motor transfer chair includes a base 1, the base includes two base longitudinal bars 11 arranged along the front and rear directions of the seat and two bases fixedly connected to the two ends of the two base longitudinal bars Cross bar 12, the front part and the middle part of said base longitudinal bar 11 are respectively hinged with front swing bar 32 and rear swing bar 31, and the upper ends of front swing bar 32 and rear swing bar 31 on each side are hinged with seats for installing seat boards. Plate mounting parts 33, the first linkage rod 34 is connected between the seat plate mounting parts 33 on both sides; the rear part of the base longitudinal rod 11 is hinged with a back support rod 21, and the upper end of the back support rod 21 is connected with the same The backrest installation part 22 for installing the backrest is connected between the rear ends of the side seat board installation parts 33, and the backrest installation part 22 is hinged with the backrest support rod 21 and the seat board installation part 33; the first linkage rod 34 A backrest electric push rod 51 for adjusting the position of the backrest is connected with the base cross bar at the rear of the seat; Install the second linkage rod 35 between the second linkage rod 35 and the first linkage rod 34 and be connected with the footrest electric pusher 52 bar for adjusting the footrest position.

Further, the footrest mechanism 4 includes a first connecting rod 41, a second connecting rod 42, a third connecting rod 43, a fourth connecting rod 44 and a footrest mounting part 45, and the front part of the seat plate mounting part is hinged with a The first connecting rod and the second connecting rod, the front end of the second connecting rod is hinged with a third connecting rod, the front end of the first connecting rod is hinged with a fourth connecting rod, and the fourth connecting rod is connected with the second connecting rod Hinged, the first connecting rod, the second connecting rod, the fourth connecting rod and the seat plate mounting part together form a parallelogram; the front ends of the third connecting rod and the fourth connecting rod are connected with a shelf for installing the footrest The foot mounting part 45 and the foot rest mounting part 45 are hinged to the third connecting rod 43 and the fourth connecting rod 44; the second linkage rod 35 is connected between the first connecting rods 41 on both sides. Of course, other footrest mechanisms may also be used.

Preferably: the backrest electric push rod 51 and the footrest electric push rod are on the same transverse plane.

The adjustable angle of the backrest mounting part 22 is 30°-80° with respect to the horizontal plane.

When the utility model was in the initial state, because the motor did not move, the footrest mechanism 4 and the backrest 2 were checked and balanced, the footrest mechanism 4 would not stretch out, and the backrest 2 would not fall down.

When the backrest 2 needs to be reclined, the user presses the control switch to make the backrest electric push rod 51 start to stretch, and drives the first linkage rod 34 to start moving, thereby driving the rear swing rod 31 to rotate counterclockwise and driving the backrest to realize reclining ; Simultaneously, the seat board mounting part 33 moves forward to drive the backrest 2 to move forward, due to the effect of the backrest support rod, the backrest can reach the maximum reclining angle without leaning against the wall; when returning, press the electric push rod Shrink the button, the backrest electric push rod 51 starts to shrink, drives the first linkage rod 34 to start to move, and rotates clockwise by the back support swing lever 31, and pulls the backrest to return to the original state.

When the footrest mechanism 4 needs to be stretched forward, the user presses the control switch to make the electric footrest push rod 52 start to extend, which drives the second linkage rod 35 to start moving, and drives the outrigger mechanism through the action of the first connecting rod 41 4 stretch out, and the first connecting rod 41 drives the second connecting rod 42, the third connecting rod 43, and the fourth connecting rod 44 at the same time, so that the footrest can reach the horizontal position, and realize the elongation of the footrest mechanism; when returning, press Control the button, the footrest electric push rod 52 starts to shrink, drives the second linkage rod 35 to start to move, and drives the outrigger mechanism to shrink through the effect of the first connecting rod 41, and drives the first connecting rod 41 to drive the second connecting rod 42, The third connecting rod 43, the fourth connecting rod 44, and the footrest mechanism 4 get back to the original position.

When the embodiment of the present utility model is in use, as long as the backrest motor push rod 51 is driven, the entire chair frame can move forward when the inclination of the backrest is adjusted, and the backrest will not touch the wall backward. Therefore, when the chair leans against the wall When placing it, you can relax and adjust the various states of the backrest without moving the chair; driving the footrest motor push rod 52 can drive the first connecting rod to drive the footrest to move to any position, which improves the comfort of the seat sex.
