[0028] 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.

[0029] In order to solve the problem in the prior art that the suspension components of the floor-standing armrest iron frame have less linkage with each component, resulting in low stability of the overall structure, the utility model provides a floor-standing armrest bracket and a floor-standing armrest sofa having the same.

[0030] Please refer to Figures 1 to 4 As 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 50; the main structure 200 includes a base frame 10, a linkage assembly 20, a footrest assembly 30 and a backrest assembly 40, the base frame 10 is movably connected to the armrest mounting plate 100 through the linkage assembly 20; the footrest assembly 30 and the backrest assembly 40 are respectively arranged to be extendable or retractable, and at least parts of the footrest assembly 30 and the backrest assembly 40 are respectively connected to the base frame 10 and the linkage assembly 20 connection; wherein the linkage assembly 20 has an active position relative to the armrest mounting plate 100, and when the linkage assembly 20 is in the active position, the minimum distance value between the linkage assembly 20 and the support base surface is greater than or equal to the minimum distance value between the armrest mounting plate 100 and the support base surface; the driving assembly 50 includes a driving member 51 connected to the linkage assembly 20 or the footrest assembly 30, so that the driving member 51 drives the footrest assembly 30 to extend to the first preset position through the base frame 10 and the linkage assembly 20, and then drives the backrest assembly 40 to extend to the second preset position.

[0031] By applying the technical solution of an embodiment of the utility model, the footrest assembly 30 and the backrest assembly 40 are respectively connected to the linkage assembly 20 and the base frame 10, and the footrest assembly 30 and the backrest assembly 40 are driven to move in sequence through the linkage assembly 20 to sequentially switch between the sitting position, the TV position and the lying position, thereby enhancing the linkage between the footrest assembly 30 and the backrest assembly 40 and the linkage assembly 20, and improving the stability of the overall structure of the armrest floor bracket. At the same time, the improved linkage assembly 20 makes the overall structure of the armrest floor bracket more compact, and the height of the lowest point of the bracket from the ground is higher, thus truly realizing high feet, which is beneficial to the cleaning work of the cleaning equipment and improves the user experience, and has low modification cost and high practicality, thereby solving the problem of low stability of the overall structure of the armrest floor-standing iron frame in the prior art due to less linkage between the suspension assembly and each assembly.

[0032] In this embodiment, the driving assembly 50 also includes a driving component 52, the driving member 51 is connected to the driving end of the driving component 52, and the driving component 52 is a linear driver. The large end (motor end) of the driving component 52 is set upward, and the motor end is connected to the rod body of the rod-shaped driving component 51.

[0033] like Figure 3 and Figure 4 As shown, the linkage assembly 20 includes a movable part 21 and a linkage part 22; the movable part 21 is movably arranged, and the backrest assembly 40 is connected to at least a part of the movable part 21; the linkage part 22 includes a linkage member 220, a moving member 221 and a connecting member 222 which are hinged in sequence, the end of the linkage member 220 away from the moving member 221 is connected to the footrest assembly 30, the middle part of the moving member 221 is hinged to the base frame 10, and the end of the connecting member 222 away from the moving member 221 is connected to at least another part of the movable part 21. In this way, when the bracket changes from the sitting position to the TV position, the driving component 52 drives the linkage component 220 through the driving component 51 to drive the foot pedal assembly 30 to extend or directly drives the foot pedal assembly 30 to extend, and at the same time, the base frame 10 also moves forward and upward, and then the linkage component 220 drives the bottom end of the moving component 221 to rotate forward, and at the same time, the connecting component 222 connected to the top of the moving component 221 drives part of the movable component 21 to move, until the foot pedal assembly 30 is extended to the limit state and officially switches to the TV position.

[0034] Specifically, the movable component 21 includes a first movable member 211, a second movable member 212, a third movable member 213, a fourth movable member 214 and a fifth movable member 215 which are hinged in sequence. The end of the first movable member 211 away from the second movable member 212 is hinged to the armrest mounting plate 100, the end of the connecting member 222 away from the moving member 221 is hinged to the middle part of the first movable member 211, the middle part of the second movable member 212 is hinged to the base frame 10, the middle part of the fourth movable member 214 is hinged to the base frame 10, the end of the fifth movable member 215 away from the fourth movable member 214 is hinged to the armrest mounting plate 100, and at least a portion of the backrest assembly 40 is hinged to the fourth movable member 214. In this way, when the bracket changes from the TV posture to the lying posture, the driving component 52 continuously drives the linkage component 220 to move forward and upward through the driving component 51. Since the footrest assembly 30 is stretched to the limit state due to the limiting effect and cannot continue to stretch, the driving component 51 at this time will pull the movable component 21 through the linkage component 22 to continue to deform, and finally the fourth movable component 214 is rotated, and the rotated fourth movable component 214 drives the backrest assembly 40 to stretch, thereby officially switching to the lying posture; and, since the middle part of the second movable component 212 is hinged to the base frame 10 and one end of the second movable component 212 is hinged to the third movable component 213, and the other end of the second movable component 212 is hinged to the first movable component 211, the overall length of the first movable component 211 is shortened in the connection of the overall structure, so that when the footrest assembly 30 and the backrest assembly 40 are both in storage, the overall structure of the linkage assembly 20 is thinner.

[0035] In this embodiment, the forward direction is the direction from the backrest assembly 40 to the footrest assembly 30 , and the rearward direction is the direction from the footrest assembly 30 to the backrest assembly 40 .

[0036] Specifically, the fourth movable member 214 is sequentially provided with a first hinge hole 2141, a second hinge hole 2142, a third hinge hole 2143 and a fourth hinge hole 2144 along its extension direction, the fifth movable member 215 is hinged to the fourth movable member 214 through the first hinge hole 2141, the third movable member 213 is hinged to the fourth movable member 214 through the second hinge hole 2142, the fourth movable member 214 is hinged to the base frame 10 through the third hinge hole 2143, and the fourth movable member 214 is hinged to at least a portion of the backrest assembly 40 through the fourth hinge hole 2144. In this way, when the bracket switches from the TV posture to the lying posture, the rotation of the moving part 221 drives the connecting part 222 to rotate, and at the same time drives the first moving part 211, the second moving part 212, the third moving part 213, the fourth moving part 214 and the fifth moving part 215 to continuously deform. Under the linkage action of the movable part 21, the fourth moving part 214 drives the backrest assembly 40 hinged to its fourth hinge hole 2144 to stretch and move to the second preset position, thereby enhancing the linkage of the overall structure; and, through the improved linkage assembly 20 of the first moving part 211, the second moving part 212, the third moving part 213, the fourth moving part 214 and the fifth moving part 215 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 30, the backrest assembly 40 and the armrest mounting plate 100, thereby reducing the overall number of connecting rods while improving the stability of the overall structure.

[0037] like Figures 2 to 4As shown, the pedal assembly 30 includes two groups of connecting rods, which are arranged alternately. One group of connecting rods includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a fourth connecting rod 34 which are hinged in sequence, and the other group of connecting rods includes a fifth connecting rod 35 and a sixth connecting rod 36 which are hinged to each other. The middle part of the second connecting rod 32 is hinged to the middle part of the fifth connecting rod 35, and the middle part of the third connecting rod 33 is hinged to the middle part of the sixth connecting rod 36. The first connecting rod 31 and the fifth connecting rod 35 are respectively hinged to the base frame 10, the linkage member 220 is hinged to the first connecting rod 31 or the fifth connecting rod 35, and the driving member 51 is connected to the linkage member 220 or one of the connecting rods in the two groups of connecting rods. In the above arrangement, the first connecting rod 31 and the second connecting rod 32, the second connecting rod 32 and the third connecting rod 33, the third connecting rod 33 and the fourth connecting rod 34, the fifth connecting rod 35 and the sixth connecting rod 36 are all arranged at a preset angle, and the preset angle L1 satisfies: 30°≤L1≤120°, and the two groups of connecting rods together form three planar quadrilateral structures, so that after the driving component 52 uses the driving component 51 to apply a driving force to a certain connecting rod of the pedal assembly 30, the connecting rods of the three planar quadrilateral structures are sequentially unfolded. , and the first connecting rod 31 and the second connecting rod 32, the second connecting rod 32 and the third connecting rod 33, the third connecting rod 33 and the fourth connecting rod 34, the fifth connecting rod 35 and the sixth connecting rod 36 are infinitely close to parallel, and the overall structure is stable and runs smoothly; at the same time, under the condition of unchanged forward extension distance, 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 30 in the sitting state.

[0038] Specifically, the footrest assembly 30 also includes a first footrest 37 and a second footrest 38, the end of the sixth connecting rod 36 away from the base frame 10 is hinged to the second footrest 38, the first footrest 37 includes a first section 371 and a second section 372 connected to each other, the second footrest 38 is hinged to the first section 371, and the end of the fourth connecting rod 34 away from the base frame 10 is respectively hinged to the second footrest 38 and the second section 372; wherein the first section 371 and the second section 372 are arranged at an angle. In the above arrangement, the first footrest 37 and the second footrest 38 are respectively used to support the user's legs, a planar quadrilateral structure is formed between the base frame 10, the first connecting rod 31, the second connecting rod 32 and the fifth connecting rod 35, a planar quadrilateral structure is formed between the second connecting rod 32, the third connecting rod 33, the fifth connecting rod 35 and the sixth connecting rod 36, and a planar quadrilateral structure is formed between the third connecting rod 33, the fourth connecting rod 34, the sixth connecting rod 36 and the first footrest 37. In this way, the three planar quadrilateral structures drive the first footrest 37 and the second footrest 38 to unfold while unfolding in sequence.

[0039] In this embodiment, the first footrest 37 and the second footrest 38 are detachably connected to the connecting rods respectively by bolts, self-tapping screws or other means.

[0040] It should be noted that, in this embodiment, the number of connecting rod groups is not limited thereto, and can be selected accordingly according to usage requirements and actual working conditions. Optionally, the connecting rod groups are one group, three groups, four groups, five groups, or more groups.

[0041] Specifically, the pedal assembly 30 further includes a stopper 39; the stopper 39 can be selectively arranged on one of the connecting rods of the two groups of connecting rods, the first footrest 37, the second footrest 38 and the base frame 10, so that when the pedal assembly 30 moves to the first preset position, the stopper 39 cooperates with a stopper close to it among the first connecting rod 31, the second connecting rod 32, the third connecting rod 33, the fourth connecting rod 34, the fifth connecting rod 35 and the sixth connecting rod 36. In this way, when the pedal assembly 30 is extended to the first preset position and the first connecting rod 31 and the second connecting rod 32, the second connecting rod 32 and the third connecting rod 33, the third connecting rod 33 and the fourth connecting rod 34, the fifth connecting rod 35 and the sixth connecting rod 36 are all in the extreme state of 120°, the stopper 39 abuts against any one of the connecting rods to keep the pedal assembly 30 in the extreme extension state, and at the same time enhance the overall stability of the pedal assembly 30.

[0042] In this embodiment, the base frame 10 includes a base body 11 and a fixed plate 12 connected to the base body 11, and the backrest assembly 40 includes a backrest mounting member 41 and a backrest connecting member 42; the backrest mounting member 41 is connected to the fixed plate 12, and the backrest mounting member 41 is used to connect to the backrest frame; one end of the backrest connecting member 42 is hinged to the backrest mounting member 41, and the other end of the backrest connecting member 42 is hinged to at least part of the linkage assembly 20, so that the driving assembly 50 drives the backrest connecting member 42 through the linkage assembly 20 to drive the backrest mounting member 41 to move to the second preset position. In this way, driven by the driving member 51, the first movable member 211, the second movable member 212, the third movable member 213, the fourth movable member 214 and the fifth movable member 215 are deformed, so that the fourth movable member 214 rotates, and then under the linkage action of the movable part 21, the backrest connecting member 42 is driven to rotate so that its lower end is closer to the base frame 10, thereby driving the backrest mounting member 41 to fall down and stretch backward to the second preset position, thereby enhancing the linkage of the overall structure to achieve the conversion of lying position; and, through the improved backrest mounting member 41 and the backrest connecting member 42 as connecting rods in the present application, the number of connecting rods of the backrest assembly 40 becomes smaller, and the backrest mounting member 41 and the backrest connecting member 42 are respectively connected to the base frame 10 and the movable part 21, so that under the linkage action of the movable part 21, the number of connecting rods of the backrest assembly 40 is reduced while the stability of the overall structure is improved.

[0043] Optionally, the base body 11 and the fixing plate 12 are an integrally formed structure, and the fixing plate 12 is an L-shaped structure.

[0044] In this embodiment, the linkage assembly 20 also has a storage position for storage relative to the armrest mounting plate 100. When the linkage assembly 20 is in the storage position, the minimum distance L1 between the linkage assembly 20 and the support base surface satisfies: 12cm≤L1≤32cm. Preferably, the minimum distance L1 between the linkage assembly 20 and the support base surface satisfies: 14cm≤L1≤29.2cm. The above-mentioned setting, through the improvement of the linkage assembly 20 and the footrest assembly 30, makes it possible for the footrest assembly 30, the backrest assembly 40 and the linkage assembly 20 to maintain a height of at least 14cm from the ground when they are in the storage state, 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, through the setting of the linkage assembly 20, the linkage between it and the footrest assembly 30 and the backrest assembly 40 is improved, and the stability of the overall structure of the bracket is enhanced.

[0045] Another aspect of the technical solution of the utility model provides a sofa with floor-standing armrests, comprising the above-mentioned floor-standing armrest bracket, and also comprising a sofa armrest or frame, wherein an armrest mounting plate 100 is fixedly mounted on the sofa armrest or frame, and the armrest mounting plate 100 always remains stationary relative to the ground, and the overall structure is stable.

[0046] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0047] The armrest floor bracket includes an armrest mounting plate, a main structure and a driving assembly; the main structure includes a base frame, a linkage assembly, a footrest assembly and a backrest assembly, and the base frame is movably connected to the armrest mounting plate through the linkage assembly; the footrest assembly and the backrest assembly are respectively arranged to be extendable or retractable, and at least parts of the footrest assembly and the backrest assembly are respectively connected to the base frame and the linkage assembly; the driving assembly includes a driving member connected to the linkage assembly or the footrest assembly, so that the driving member drives the footrest assembly to extend to a first preset position through the base frame and the linkage assembly, and then drives the backrest assembly to extend to a second preset position. In this way, the footrest assembly and the backrest assembly are respectively connected to the linkage assembly and the base frame, and the linkage assembly is used to drive the footrest assembly and the backrest assembly to move in sequence, so as to switch between the sitting position, TV position and lying position in sequence, thereby enhancing the linkage between the footrest assembly and the backrest assembly and the linkage assembly, and improving the stability of the overall structure of the armrest floor bracket. At the same time, the improved linkage assembly makes the overall structure of the armrest floor bracket more compact, and the height of the lowest point of the bracket from the ground is higher, thus realizing high feet in a true sense, which is beneficial to the cleaning work of the cleaning equipment and improves the user experience. The modification cost is low and the practicality is high, thereby solving the problem of low stability of the overall structure caused by less linkage between the suspension assembly and each assembly of the armrest floor-standing iron frame in the prior art.

[0050] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0051] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
