DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to solve the problem in the prior art that when a floor-standing sofa with armrests is placed, the distance between its backrest and the wall is too close, resulting in the inability to switch the sofa mode, the utility model provides an armrest floor-standing bracket and a zero-wall armrest floor-standing sofa with the same.

[0029] Please refer to Figures 1 to 3As shown, one aspect of the technical solution of the utility model is applied, the armrest floor bracket includes an armrest mounting plate 100, a main structure 200 and a driving assembly 40; the main structure 200 includes a base frame 10, a linkage assembly 20 and a backrest assembly 30, the base frame 10 is movably connected to the armrest mounting plate 100 through the linkage assembly 20; the backrest assembly 30 includes a third backrest connector 34, a backrest mounting member 31, a first backrest connector 32 and a second backrest connector 33, one end of the second backrest connector 33 is connected to the linkage assembly 20, and the second backrest connector 33 is connected to the linkage assembly 20. At least a portion of the assembly 20 is hinged, one end of the third backrest connecting member 34 is hinged to at least another portion of the linkage assembly 20, the middle portion of the first backrest connecting member 32 is hinged to the base frame 10, and the backrest mounting member 31 has a reclining position inclined relative to the armrest mounting plate 100 and a storage position stored relative to the armrest mounting plate 100; the driving assembly 40 includes a driving member 41 connected to the linkage assembly 20, so that the driving member 41 drives the backrest mounting member 31 to move from the storage position to the reclining position through the base frame 10 and the linkage assembly 20.

[0030] In one aspect of an embodiment of the present invention, the third backrest connector 34, the backrest mounting member 31, the first backrest connector 32 and the second backrest connector 33 form a planar quadrilateral structure, so that the second backrest connector 33 and the third backrest connector 34 are respectively hinged to the linkage assembly 20, and the linkage assembly 20 drives the second backrest connector 33 and the third backrest connector 34 to approach each other and cross-move, so that the first backrest connector 32 and the backrest mounting member 31 are also driven to approach each other and cross-move. At this time, the backrest mounting member 31 moves forward and falls backward from the storage position to the reclining position. The arrangement of the second backrest connector 33 increases the forward movement distance of the backrest mounting member 31, so that the backrest mounting member 31 does not interfere with the wall when it falls and moves to the reclining position, achieving zero wall contact, thereby solving the problem in the prior art that the distance between the backrest and the wall of the armrest floor-standing sofa when placed is too close to realize the sofa mode switching.

[0031] In this embodiment, the driving assembly 40 also includes a driving component, which is connected to the armrest mounting plate 100 through a connecting rod, and the driving member 41 is connected to the driving end of the driving component, and the driving component is a linear driver. The big head (motor end) of the driving component is set upward, and the motor end is connected to the rod body of the rod-shaped driving member 41.

[0032] like Figure 3As shown, the linkage assembly 20 includes a linkage part 21 and a movable part 22; the linkage part 21 is movably connected to the base frame 10, and the driving member 41 is connected to the linkage part 21; the linkage part 21 is connected to at least a part of the movable part 22, and the second backrest connecting member 33 and the third backrest connecting member 34 are respectively connected to at least another part of the movable part 22, so that the driving assembly 40 drives the backrest mounting member 31 to move through the linkage part 21 and the movable part 22. In this way, when the bracket switches from the TV position to the lying position, the driving component drives the linkage component 21 and the movable component 22 in sequence through the driving component 41 to drive the second backrest connecting member 33 and the third backrest connecting member 34 to approach each other and move crosswise, thereby synchronously driving the backrest mounting member 31 and the first backrest connecting member 32 to approach each other and move crosswise. In this way, the forward movement distance of the backrest mounting member 31 is increased, so that the backrest mounting member 31 moves forward a short distance before falling backwards, ensuring that it will not interfere with the wall when switching to the lying position. At the same time, the backrest assembly 30 enhances the linkage between it and the linkage assembly 20, thereby improving the stability of the overall structure of the backrest assembly 30 and making it have a better force effect.

[0033] Specifically, the movable component 22 includes a first movable component 221, a second movable component 222, a third movable component 223, a fourth movable component 224 and a fifth movable component 225 which are hinged in sequence. The end of the first movable component 221 away from the second movable component 222 is hinged to the armrest mounting plate 100, the middle part of the first movable component 221 is hinged to the linkage component 21, the middle part of the second movable component 222 is hinged to the base frame 10, the fourth movable component 224 is hinged to the base frame 10, the end of the fifth movable component 225 away from the fourth movable component 224 is hinged to the armrest mounting plate 100, and the second backrest connecting component 33 and the third backrest connecting component 34 are respectively hinged to the fourth movable component 224. In this way, when the bracket switches from the TV position to the lying position, the driving component drives the linkage component 21 to move through the driving component 41, and then the linkage component 21 drives the first movable member 221, the second movable member 222, the third movable member 223, the fourth movable member 224 and the fifth movable member 225 to deform, so that the fourth movable member 224 rotates and drives the second backrest connecting member 33 and the third backrest connecting member 34 to approach each other and move crosswise, so that the backrest mounting member 31 is driven by it to move synchronously to the reclining position to complete the switching of the lying position, and there will be no interference with the wall during the movement, thus achieving zero leaning against the wall.

[0034] In this embodiment, the second backrest connecting member 33 and the third backrest connecting member 34 are both connected to the fourth movable member 224, so that the linkage is better and the force is better, so that the overall structure of the backrest assembly 30 is more stable.

[0035] Specifically, the fourth movable member 224 is sequentially provided with a first hinge hole 2241, a second hinge hole 2242, a third hinge hole 2243, a fourth hinge hole 2244 and a fifth hinge hole 2245 along its extension direction, the second backrest connecting member 33 is hinged to the fourth movable member 224 through the first hinge hole 2241, the fifth movable member 225 is hinged to the fourth movable member 224 through the second hinge hole 2242, the third movable member 223 is hinged to the fourth movable member 224 through the third hinge hole 2243, the fourth movable member 224 is hinged to the base frame 10 through the fourth hinge hole 2244, and the third backrest connecting member 34 is hinged to the fourth movable member 224 through the fifth hinge hole 2245. In this way, when the bracket switches from the TV posture to the lying posture, the driving component drives the linkage component 21 to move through the driving component 41, and at the same time drives the first movable member 221, the second movable member 222, the third movable member 223, the fourth movable member 224 and the fifth movable member 225 to continuously deform. Under the linkage action of the movable member 22, the fourth movable member 224 rotates, driving the second backrest connecting member 33 and the third backrest connecting member 34 hinged to the first hinge hole 2241 and the fifth hinge hole 2245 respectively to approach each other and cross-move, thereby bringing The dynamic backrest mounting member 31 moves from the storage position to the reclining position, which enhances the linkage of the overall structure; and, through the improved linkage assembly 20 having the first movable member 221, the second movable member 222, the third movable member 223, the fourth movable member 224 and the fifth movable member 225 as connecting rods in the present application, the number of connecting rods becomes smaller, and each connecting rod is respectively connected to the base frame 10, the footrest assembly 50, the backrest assembly 30 and the armrest mounting plate 100, thereby reducing the overall number of connecting rods while improving the stability of the overall structure.

[0036] like Figure 3 As shown, a limiting groove 320 is provided on the first backrest connecting member 32, and a first limiting member 11 is provided on the base frame 10. The first limiting member 11 is movably provided in the limiting groove 320, so that when the backrest assembly 30 moves from the storage position to the reclining position, the first limiting member 11 moves from one end of the limiting groove 320 to the other end. In this way, in the sitting position and TV position state, the first limiting member 11 on the first backrest connecting member 32 abuts against one end of the limiting groove 320. When the bracket switches from the TV position to the lying position, the first limiting member 11 on the first backrest connecting member 32 moves from one end of the limiting groove 320 to the other end and abuts, so that the backrest assembly 30 is limited by the first limiting member 11 and the limiting groove 320 in the sitting position, TV position and lying position, thereby enhancing the stability of the overall structure of the backrest assembly 30.

[0037] Specifically, the armrest floor stand also includes a footrest assembly 50, which is extendably or retractably connected to the base frame 10 through the linkage assembly 20. The linkage component 21 includes a linkage component 210, a moving component 211 and a connecting component 212 that are hinged in sequence. The end of the linkage component 210 away from the moving component 211 is connected to the footrest assembly 50, the middle part of the moving component 211 is hinged to the base frame 10, and the end of the connecting component 212 away from the moving component 211 is connected to at least part of the movable component 22. In this way, when the bracket is changed from the sitting position to the TV position, the driving component drives the linkage member 210 through the driving member 41 to drive the foot pedal assembly 50 to extend or directly drives the foot pedal assembly 50 to extend, and at the same time, the base frame 10 also moves forward and upward, and then the linkage member 210 drives the bottom end of the moving member 211 to rotate forward, and at the same time, the connecting member 212 connected to the top of the moving member 211 drives the first movable member 221 and the fifth movable member 225 of the movable member 22 to move, until the foot pedal assembly 50 is limited and extended to the extreme state to officially switch to the TV position.

[0038] When the bracket changes from the TV posture to the lying posture, the driving component continuously drives the linkage member 210 to move forward and upward through the driving member 41. Since the footrest assembly 50 has been extended to the limit state and can no longer be extended, the driving member 41 at this time will pull the movable member 22 through the linkage member 21 to continue to deform, and finally the fourth movable member 224 will rotate, and the rotated fourth movable member 224 will drive the second backrest connecting member 33 and the third spare connecting member 212 to approach each other and move crosswise, so that the backrest mounting member 31 moves from the storage position to the reclining position to realize the formal switch of the lying posture.

[0039] In the present embodiment, the forward direction is the direction from the backrest assembly 30 to the footrest assembly 50 , and the rearward direction is the direction from the footrest assembly 50 to the backrest assembly 30 .

[0040] like Figure 2 and Figure 3As shown, the pedal assembly 50 includes two groups of connecting rods, a first footrest 57 and a second footrest 58; the two groups of connecting rods are arranged alternately, one group of connecting rods includes a first connecting rod 51, a second connecting rod 52, a third connecting rod 53 and a fourth connecting rod 54 which are hinged in sequence, and the other group of connecting rods includes a fifth connecting rod 55 and a sixth connecting rod 56 which are hinged to each other, the middle part of the second connecting rod 52 is hinged to the middle part of the fifth connecting rod 55, the middle part of the third connecting rod 53 is hinged to the middle part of the sixth connecting rod 56, the first connecting rod 51 and the fifth connecting rod 55 are respectively hinged to the base frame 10, and the linkage member 21 0 is hinged to the first connecting rod 51 or the fifth connecting rod 55, and the driving member 41 can be selectively connected to the linkage member 210 and one of the connecting rods of the two groups of connecting rods; the sixth connecting rod 56 is hinged to the second footrest 58 at one end away from the base frame 10, the first footrest 57 includes a first section 571 and a second section 572 connected to each other, the second footrest 58 is hinged to the first section 571, and the fourth connecting rod 54 is hinged to the second footrest 58 and the second section 572 at one end away from the base frame 10; wherein the first section 571 and the second section 572 are arranged at an angle.

[0041] In the above arrangement, a preset angle is formed between the first connecting rod 51 and the second connecting rod 52, the second connecting rod 52 and the third connecting rod 53, the third connecting rod 53 and the fourth connecting rod 54, and the fifth connecting rod 55 and the sixth connecting rod 56, and the preset angle L1 satisfies: 30°≤L1≤120°, and a planar quadrilateral structure is formed between the base frame 10, the first connecting rod 51, the second connecting rod 52 and the fifth connecting rod 55, a planar quadrilateral structure is formed between the second connecting rod 52, the third connecting rod 53, the fifth connecting rod 55 and the sixth connecting rod 56, a planar quadrilateral structure is formed between the third connecting rod 53, the fourth connecting rod 54, the sixth connecting rod 56 and the first footrest 57, and the first footrest 57 and the second footrest 58 are respectively used to support the user's legs. In this way, by driving After the component utilizes the driving member 41 to apply a driving force to a certain connecting rod of the footrest assembly 50, the connecting rods of the three planar quadrilateral structures are sequentially unfolded, and the first connecting rod 51 and the second connecting rod 52, the second connecting rod 52 and the third connecting rod 53, the third connecting rod 53 and the fourth connecting rod 54, the fifth connecting rod 55 and the sixth connecting rod 56 are infinitely close to parallel, and the overall structure is stable and operates smoothly. When the three planar quadrilateral structures are sequentially unfolded, the first footrest 57 and the second footrest 58 are driven to unfold; at the same time, while the forward extension distance remains unchanged, the lengths of the six connecting rods in this embodiment are shortened, so that the shortened connecting rods occupy less vertical space when stored, so as to achieve a thinner storage thickness of the footrest assembly 50 in the sitting state.

[0042] In another embodiment, the driving member 41 is connected to the pedal assembly 50 through a transmission member 60 to drive the pedal assembly 50 to extend or contract. The transmission member 60 includes a seventh link 61 and an eighth link 62 that are hinged to each other. The end of the seventh link 61 away from the eighth link 62 is hinged to the base frame 10, and the seventh link 61 is located between the linkage member 210 and the base frame 10. The end of the eighth link 62 away from the seventh link 61 is connected to the driving member 41, and the eighth link 62 is hinged to the fifth link 55, so that when the driving member drives the driving member 41 to move, the eighth link 62 drives the pedal assembly 50 to extend or contract, and drives the linkage member 210 to move. In this way, on the basis of driving the backrest assembly 30 and the pedal assembly 50 to move, the overall running distance of the driving member 41 is shortened, the service life of the driving member 41 is increased, and the overall flexibility is stronger.

[0043] In this embodiment, the first footrest 57 and the second footrest 58 are respectively connected to the connecting rod in a detachable manner by bolts, self-tapping screws or other means.

[0044] It should be noted that, in the present embodiment, the number of connecting rods is not limited thereto, and can be selected accordingly according to the use requirements and actual working conditions. Optionally, the connecting rods are one group, three groups, four groups, five groups, or more groups. Specifically, the pedal assembly 50 further includes a second limit member 59; the second limit member 59 can be selectively arranged on one of the connecting rods of the two groups of connecting rods, the first footrest member 57, the second footrest member 58, and the base frame 10, so that when the pedal assembly 50 is extended to the first preset position, the second limit member 59 cooperates with a limit position close to it among the first connecting rod 51, the second connecting rod 52, the third connecting rod 53, the fourth connecting rod 54, the fifth connecting rod 55, and the sixth connecting rod 56. In this way, when the foot pedal assembly 50 is extended to the extreme state of 120° between the first link 51 and the second link 52, the second link 52 and the third link 53, the third link 53 and the fourth link 54, and the fifth link 55 and the sixth link 56, the second limit member 59 abuts against any one of the links to keep the foot pedal assembly 50 in the extreme extension state, while enhancing the overall stability of the foot pedal assembly 50.

[0045] In this embodiment, the linkage assembly 20 has a retracted position for storage relative to the armrest mounting plate 100. When the linkage assembly 20 is in the retracted position, the minimum distance L1 between the linkage assembly 20 and the support base surface satisfies: 12cm≤L1≤32cm. In the above configuration, preferably, the minimum distance L1 between the linkage assembly 20 and the support base surface satisfies: 14cm≤L1≤29.2cm. By improving the linkage assembly 20 and the footrest assembly 50, when the footrest assembly 50, the backrest assembly 30 and the linkage assembly 20 are all in the storage state, the height between them and the ground is maintained at least 14cm, realizing a true high-legged sofa (usually a sofa greater than 12cm can be called a high-legged sofa, but the present application can achieve a height of at least 14cm from the ground). At the same time, by configuring the linkage assembly 20, the linkage between it and the footrest assembly 50 and the backrest assembly 30 is improved, and the stability of the overall structure of the bracket is enhanced.
