Description
Technical Field

Background
The sofa is a foreign word and is transliterated according to the English word sofa. Is a multi-seat chair with soft cushions. The back rest chair with springs or thick foam plastic is one kind of soft furniture with armrests on two sides. The origin of the sofa can be traced to ancient Egypt around 2000 before the male element, but the true soft-packed sofa appears from the end of the sixteenth century to the beginning of the seventeenth century.
The traditional sofa structure is usually fixed, and can not be switched according to actual use requirements in leaning and lying states during actual use, so that the comfort level and flexibility of use are poor, and daily use requirements can not be well met.
In order to meet the requirement that a user sitting on the sofa can flexibly adjust and switch between leaning and lying states. The existing sofa is usually provided with a backrest, a sitting piece and a foot rest on a base, and the three parts are driven to move through a driving assembly to realize the switching of the sofa in leaning and lying states. However, the following problems still remain in the sofa:
1, if each part is connected with a driving component through a transmission mechanism, the connected parts are driven to move through three driving components to realize the switching of the sofa in leaning and lying states. However, the sofa needs to be provided with a plurality of driving components, and has a huge and complex structure and high production cost.
2, in the conventional sofa, in the movement process of switching the leaning state to the lying state, usually, the backrest member is tilted down successively, and the leg rest is rotated again to be lifted. However, when the backrest falls down in succession, the user's feet are still dragged on the ground, and the human body has a certain uncomfortable feeling.
3, if a single driving component is adopted to drive the back rest, the sitting part and the foot rest simultaneously, the three parts of the back rest, the sitting part and the foot rest always have synchronous movement, and the problem of back rubbing and waist running possibly occurs in the movement process. And the stroke ranges among all the components are not necessarily the same, and if synchronous motion is always kept among the three components, the problem that one component moves beyond the stroke range can occur.

And grooves 40 extending along the length direction of the strip-shaped insert block 38 are formed in the upper and lower side walls of the strip-shaped insert block. By providing the grooves 40 on the side walls of the strip-shaped inserts 38, the strip-shaped inserts 38 form a profiled member, which improves the structural strength of the strip-shaped inserts 38 and avoids breakage of the strip-shaped inserts 38 during rotation.
At the same time, the connecting rod 18 interferes with the seat 4 in order to avoid that the connecting rod 18 is directly connected to the support 6, which would cause the foot rest 2 to rotate to the extended position. In this scheme, a first fixed connecting piece 41 extending towards a direction away from the supporting plate 5 is arranged on an end face of one side of the supporting piece 6 away from the supporting plate 5, and the first fixed connecting piece 41 is hinged with the connecting rod 18. In order to avoid interference between the transmission element 9 and the first fixed connection 41, a second fixed connection 42 extending away from the support plate 5 is provided on the end face of the side facing away from the support plate 5, and the second fixed connection 42 is hinged to the transmission rod.
And in this scheme, when the foot rest 2 rotates to the unfolding position, the foot rest transmission mechanism 8 acts on the seat transmission mechanism 7 to enable the seat transmission mechanism 7 to be connected with the driving assembly 10, so that the power of the driving assembly 10 can be simultaneously transmitted to the seat transmission mechanism 7 to drive the seat 4 and the backrest 3 to move.
Specifically, as shown in fig. 8, the leg rest transmission mechanism 8 further includes a pushing member 22, the pushing member 22 is movably disposed on the base 1, a limiting groove 23 extending along the height direction of the pushing member 22 is disposed on the base 1, and one side of the pushing member 22 is disposed in the limiting groove 23 and can slide in the limiting groove 23. While the pushing member 22 is located in the path of travel of the transmission member 9. When the transmission member 9 drives the foot rest 2 to move to the unfolding position, the pushing member 22 is lifted up by the corresponding part of the transmission member 9, so that the pushing member 22 acts on the second transmission rod 15 and drives the second transmission rod 15 to move until the driving assembly 10 is connected.
More specifically, as shown in fig. 1 and 8, the transmission member 9 in this embodiment is provided with a slope 24. As a preferred embodiment, the transmission member 9 is provided with a clamping groove 25 extending along a length direction thereof, a chute 26 is arranged at a bottom of the clamping groove 25, the extending direction of the chute 26 is the same as that of the clamping groove 25, the chute 26 has a head end and a tail end along the length direction thereof, the head end of the chute 26 is adjacent to the driving assembly 10, and a wall of the tail end of the chute 26 extends outwards from the bottom of the chute to the slot to form the slope 24. The bottom end of the pushing piece 22 is placed in the chute 26, and when the foot rest 2 moves to the unfolding position, the slope 24 pushes against the pushing piece 22 and pushes up the pushing piece 22, so that the pushing piece 22 acts on the second transmission rod 15 and drives the second transmission rod 15 to move along the length direction of the second transmission rod until the second transmission rod is connected with the driving assembly 10.
And in order to allow the second transmission rod 15 to be connected to the drive assembly 10. As shown in fig. 8 and 12, in this embodiment, the second transmission rod 15 has a head end and a tail end along its length direction, the head end of the second transmission rod 15 is provided with a plug connector 27, the third transmission rod 12 is provided with a fixing member 35, and the fixing member 35 is provided with a slot 28. When the pushing piece 22 acts on the second transmission rod 15, the plug-in piece 27 is in plug-in fit with the slot 28, so that the second transmission rod 15 is connected with the driving assembly 10.
In order to enable the pushing element 22 to act on the second transmission rod 15, the plug element 27 can be inserted into the slot 28. In this embodiment, the pushing member 22 has a first inclined surface 31, and the plug member 27 of the second transmission rod 15 is provided with a first boss 29. When the slope 24 abuts against the pushing member 22 and lifts the pushing member 22, the first inclined surface 31 on the pushing member 22 abuts against the table edge of the first boss 29 and drives the second transmission rod 15 to move along the length direction until the plug member 27 is in plug-in fit with the slot 28. And the pushing piece 22 is propped against the side wall of the first boss 29 at this time, so that the plug-in piece 27 is prevented from being separated from the slot 28.
In this embodiment, the base 1 is further provided with an elastic member 34, the elastic member 34 acts on the pushing member 22, and when the slope 24 on the transmission member 9 lifts the pushing member 22, the elastic member 34 deforms. Specifically, the elastic member 34 is a spring, the spring is disposed in the limiting groove 23, and the spring abuts against the top end of the pushing member 22. When the slope 24 pushes up the pushing member 22 against the bottom end of the pushing member 22, the pushing member 22 is lifted up, and the spring is deformed and compressed.
Subsequently, when the driving motor 11 continues to drive the first transmission rod 13 to rotate, so that the footrests 2 move from the unfolding position to the extending position, the driving motor 11 synchronously drives the second transmission rod 15 to rotate, so as to drive the sitting piece 4 to incline and ascend along the length direction of the second transmission rod 15. Since the second transmission rod 15 is parallel to the first transmission rod 13, the moving directions of the sitting piece 4 and the transmission piece 9 are kept consistent, the moving directions of the connecting rod 18 and the transmission piece 9 are kept consistent, the foot rest 2 is driven to move in parallel between the unfolding position and the extending position along the length direction of the first transmission rod 13, and the foot rest 2 is not rotated in the process. In this process, the bottom end of the pushing member 22 slides in the clamping groove 25 on the transmission member 9, and limiting of the pushing member 22 is achieved through the groove walls on both sides of the clamping groove 25.
At the same time, the second transmission rod 15 drives the fourth transmission rod 16 to rotate, so as to drive the backrest 3 to rotate to the reclined position at the bearing position. In order to rotate the backrest 3 into the reclined position in the rest position. As shown in fig. 3, the base 1 is further provided with a guide groove 20, an included angle is formed between the guide groove 20 and the fourth transmission rod 16, a guide block 21 is slidably disposed in the guide groove 20, and the guide block 21 is connected with the backrest 3. The backrest 3 is guided by the guide groove 20, and the backrest 3 moves along the fourth transmission rod 16, and at the same time, the backrest 3 rotates relative to the base 1 due to different movement directions of the backrest connecting piece and the guide block 21, so that the backrest is rotated from the leaning position to the leaning position, and the sofa is in a lying state.
It will be readily appreciated that during rotation of the sofa from the sitting to the lying position, the footrest is first rotated from the stowed position to the extended position. The user's foot can lift in advance, can not drag on ground all the time at sofa deformation in-process foot, has improved user's use experience, and is more comfortable. And in the process of the movement of the foot rest 2 between the unfolding position and the extending position, the sitting piece 4 moves along the length direction of the second transmission rod 15, the backrest 3 moves along the direction of the fourth transmission rod 16, and the three parts always keep synchronous movement, so that the problem of back rubbing and waist running is avoided.
And preferably, in the scheme, the included angle between the second transmission rod 15 and the horizontal plane is larger than the included angle between the fourth transmission rod 16 and the horizontal plane, and the fourth transmission rod 16 is almost parallel to the horizontal plane. Since the sitting part 4 needs to be lifted, an included angle is necessarily formed between the second transmission rod 15 and the horizontal plane, and if the fourth transmission rod 16 extends obliquely like the second transmission rod 15, the height of the base 1 is greatly increased, and the cost is increased. The included angle between the second transmission rod 15 and the horizontal plane is larger than the included angle between the fourth transmission rod 16 and the horizontal plane, so that the fourth transmission rod 16 is almost parallel to the horizontal plane, the height of the base 1 is reduced, and the length of the backrest 3 is also greatly reduced.
Meanwhile, in this embodiment, the pitch of the second transmission rod 15 is different from the pitch of the fourth transmission rod 16. The pitch of the second transmission rod 15 is smaller than the pitch of the fourth transmission rod 16. Since the same driving assembly 10 drives the second transmission rod 15 and the fourth transmission rod 16 to rotate synchronously, the rotation numbers of the second transmission rod 15 and the fourth transmission rod 16 are the same. In order to avoid the problem of waist pinching and back rubbing during the angle adjustment process, the pitch of the threads on the second transmission rod 15 is smaller than the pitch of the threads on the fourth transmission rod 16, so that when the same number of turns are rotated, the distance moved by the backrest connecting piece is larger than the distance moved by the seat connecting piece 17, the rotating speed of the backrest 3 is faster than the lifting speed of the seat 4, and the problem of waist pinching and back rubbing during the angle adjustment process can be avoided.
And when the user wants to switch the sofa from the lying state to the sitting state, only the motor 11 needs to be driven in reverse. The driving motor 11 drives the first transmission rod 13 and the second transmission rod 15 to reversely rotate. In the process, the transmission member 9 is retracted to bring the footrest 2 from the extended position to the extended position. At the same time, the landing gear 4 moves obliquely downward and retreats. The backrest 3 is retracted synchronously and rotated from the reclined position into the rest position.
When the footrest 2 is retracted to the extended position, the bottom end of the pushing member 22 is again abutted against the slope 24, and as the transmission member 9 is retracted, the bottom end of the pushing member 22 is separated from the slope 24, and the bottom end of the pushing member 22 is not limited. The restoring force of the spring forces the pushing member 22 downward at this time. The pushing piece 22 acts on the second transmission rod 15 to force the second transmission rod 15 to move back along the length direction until the plug-in piece 27 on the second transmission rod 15 is withdrawn from the slot 28 on the fixed block.
In order to allow the pushing element 22 to act again on the second transmission rod 15, the pushing element 22 has, in particular, a second inclined surface 32, the second inclined surface 32 being oriented opposite to the first inclined surface 31. Meanwhile, a second boss 30 is further arranged on the plug connector 27 at the head end of the second transmission rod 15, and the pushing piece 22 is located between the second boss 30 and the first boss 29. When the restoring force of the spring forces the pushing member 22 to move downwards, the second inclined surface 32 on the pushing member 22 abuts against the table edge of the second boss 30, so that the second transmission rod 15 moves reversely until the plug-in connector 27 on the second transmission rod 15 exits the slot 28 on the fixed block.
In this embodiment, as shown in fig. 8, the pushing member 22 is provided with a relief through groove 33, and the relief through groove 33 penetrates through the front and rear end surfaces of the pushing member 22 along the thickness direction of the pushing member 22. The first transmission rod 13 and the plug-in element 27 each extend through the relief channel 33.
At this time, since the second transmission rod 15 is disconnected from the driving motor 11, the seat 4 and the backrest 3 remain relatively stationary with respect to the base 1 again, so as to avoid exceeding the travel range due to the continued retraction of the seat 4 and the backrest 3. Subsequently, the driving motor 11 alone drives the first transmission rod 13 to reversely rotate, and the transmission member 9 continuously retreats, so that the foot rest 2 rotates from the unfolding position to the folding position, and the sofa is switched to the sitting state.
In this embodiment, the number of the bases 1 is two, the seat 4 and the backrest 3 are located between the two bases 1 in the horizontal direction, and the two bases 1 are provided with a seat transmission mechanism 7 and a leg rest transmission mechanism 8. But only one driving motor 11 is arranged on the two bases 1, the driving motor 11 is a double-shaft driving motor, and output shafts at two ends of the driving motor 11 are respectively connected with a third transmission rod 12 on the two bases 1 to drive the seat transmission mechanism 7 and the leg rest transmission mechanism 8 to move.
Example 2: referring to fig. 14 and 15, the main difference between the present embodiment and the above embodiment 1 is that the present embodiment further includes a handrail seat, and the handrail seat and the seat connecting member 17 are located at two opposite sides of the base 1. In this embodiment, the seat connecting piece 17 includes a seat connecting plate 44 and a seat connecting block 45, where the seat connecting block 45 is in screwed connection with the second transmission rod 15, and the seat connecting plate 44 is fixedly connected with the seat connecting block 45 and the seat bearing piece 4.
Meanwhile, a first guiding through groove 46 is formed in the base 1, the extending direction of the first guiding through groove 46 is the same as that of the second transmission rod 15, the seat connecting block 45 penetrates through the first guiding through groove 46, the armrest seat is provided with an armrest connecting piece 43, and the armrest connecting piece 43 is connected with the seat connecting block 45. As a preferred connection mode, in the scheme, the armrest connecting piece 43 and the seat connecting block 45 are fixedly connected through screws, so that the armrest seat is convenient to assemble and disassemble.
When the driving assembly 10 drives the second transmission rod 15 to rotate, the sitting piece 4 moves along the length of the second transmission rod 15 to realize lifting. Meanwhile, since the seat connecting block 45 is connected with the armrest connecting piece 43, the armrest seat and the seat supporting piece 4 can be driven to synchronously lift, so that the elbow of the user can be always placed on the armrest seat comfortably.
In order to avoid the tendency of the seat connecting piece 17 and the armrest seat to rotate when the seat connecting piece 45 moves along the second transmission rod 15, the seat connecting piece 45 is provided with an annular protrusion, and the side wall of the annular protrusion abuts against the side wall of the base 1.
In addition, the base 1 is further provided with a plurality of second guiding through grooves 47, the extending direction of the second guiding through grooves 47 is the same as the extending direction of the first guiding through grooves 46, guiding pieces 48 are slidably arranged in the extending of the second guiding through grooves 47, and two ends of each guiding piece 48 are respectively connected with the armrest connecting pieces 43 and the seat connecting plates 44. Through being provided with second direction through groove 47 and guide 48, provide more support to handrail seat and seat connecting plate 44 for overall structure is more problematic, and it is more smooth to go up and down.
It should be noted that, since the shape and structure of the armrest may be various and the shape thereof is not fixed, the shape and structure of the armrest seat is not shown in the drawings, and how the armrest seat is connected to the seat connecting member 17 is only expressed by the connection relationship between the armrest connecting member 43 and the seat connecting member 17.
