Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example: Refer to Figures 1-5The present invention discloses a soft sofa structure with adjustable seating comfort, comprising:

[0036] The sofa frame 1 has a seat frame 2 at its top. The seat frame 2 has a rotating shaft 3 on both sides. Several guide wheels 4 are eccentrically arranged on the outer peripheral wall of the rotating shaft 3. Support webbing 5 is arranged on the outer peripheral wall of two opposite guide wheels 4.

[0037] The drive assembly 6 is located on both sides of the seat frame 2 and is used to drive the rotating shaft 3 to rotate.

[0038] Spring filling 7 is located at the bottom inside of the sofa frame 1 to provide support for the support webbing 5;

[0039] The guide component 8, which is located inside the sofa frame 1, is used to guide the spring filling 7.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, when adjusting the firmness of the sofa, the drive assembly 6 drives the rotating shafts 3 on both sides to deflect at an angle. Since the two ends of the support webbing 5 are fixedly connected to the outer peripheral walls of the guide wheels 4 on both sides, when the two rotating shafts 3 rotate outward relative to each other, the support webbing 5 can be stretched through the guide wheels 4 on both sides. At this time, the support webbing 5 will be tightened, and the support of the support webbing 5 on the sofa upholstery will be improved. Therefore, when sitting on the upper part of the upholstery, the deformation of the support webbing 5 is greatly reduced, and only the sofa upholstery deforms. At this time, the sofa can be suitable for family members who prefer a firmer sofa.

[0041] On the other hand, when the guide wheels 4 on both sides rotate inwards, the support straps 5 will loosen. At this time, when sitting on the upper part of the soft cushion, both the sofa soft cushion and the support straps 5 will deform, making the sofa suitable for family members who prefer soft sofas, which can effectively improve the applicability of the sofa.

[0042] The spring filler 7 is used to provide support for the support bandage 5, and when the guide wheels 4 on both sides rotate, they will pull the spring filler 7 to move, so as to compress the spring filler 7.

[0043] The guide component 8 is used to improve the stability of the movement of the spring filler 7 as it moves.

[0044] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the bottom side of the seat frame 2 is provided with a number of rotating grooves 9, the number of rotating grooves 9 is equal to the number of guide wheels 4, and the guide wheels 4 are located inside the rotating grooves 9. The top of the side wall of the seat frame 2 is provided with an arc plate 10 for guiding the support bandage 5.

[0045] In this embodiment, the rotating groove 9 is used to position the guide wheel 4, and the two side walls of the rotating groove 9 are in contact with the two side walls of the positioning guide wheel 4 to improve the stability of the positioning guide wheel 4 during rotation. The arc plate 10 reduces the friction between the support bandage 5 and the seat plate frame 2 when the support bandage 5 is stretched and moved, thereby improving the service life of the support bandage 5.

[0046] In a further preferred embodiment of this utility model, such as Figure 2 As shown, several bolts 11 are fixedly installed at both ends of the support bandage 5, and several screw holes that are threaded to the bolts 11 are provided on the outer peripheral wall of the guide wheel 4.

[0047] In this embodiment, the bolts 11 and screw holes are used to fix the two ends of the support bandage 5 to the guide wheels 4 at the corresponding positions, so that when the guide wheels 4 on both sides rotate relative to each other, they can stretch the support bandage 5 or loosen the support bandage 5, so as to achieve the purpose of adjusting the support force provided by the support bandage 5.

[0048] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the driving component 6 includes:

[0049] The outer housing 61 is fixedly installed inside the seat plate frame 2;

[0050] The drive shaft 62 is rotatably disposed inside the outer housing 61, and one end extends through the outer housing 61;

[0051] Two connecting shafts 63 are respectively disposed at both ends of the outer housing 61, and the axes of the two connecting shafts 63 are perpendicular to the axis of the outer housing 61. The two connecting shafts 63 are fixedly connected to the two rotating shafts 3 respectively, and both connecting shafts 63 are connected to the transmission shaft 62 through the worm gear assembly 64.

[0052] In this embodiment, preferably, a rotating handle can be provided at one end of the transmission shaft 62 that passes through the outer housing 61, so as to adjust the rotating shaft 3 by manually rotating the transmission shaft 62 and then by connecting shafts 63 on both sides. Alternatively, a drive motor can be provided to replace manual driving of the transmission shaft 62. This will not be described in detail in this example, as those skilled in the art can fully understand it.

[0053] like Figure 3As shown, the worm gear assembly 64 is used to drive the connecting shaft 63 and the transmission shaft 62. Specifically, the worm gear assembly 64 includes a worm wheel and a worm sleeve. The worm wheel is fixedly connected to one end of the connecting shaft 63, and the worm sleeve is sleeved on the outer peripheral wall of the transmission shaft 62 and cooperates with the worm wheel. At this time, by rotating the transmission shaft 62, the worm wheel can be driven to rotate through the worm sleeve, thereby achieving the purpose of driving the connecting shaft 63 to rotate.

[0054] Furthermore, the worm gear sleeves in the two sets of worm gear assemblies 64 have opposite worm directions, so as to drive the two connecting shafts 63 to rotate in opposite directions.

[0055] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the spring filler 7 includes:

[0056] The base plate 71 is slidably set at the bottom end of the sofa frame 1. Several tension steel cables 72 are provided on both sides of the base plate 71, and the top end of the tension steel cables 72 is fixedly connected to the guide wheel 4.

[0057] Multiple support springs 73 are arranged in a rectangular array on the top of the base plate 71, and the top of each support spring 73 is in contact with the bottom wall of the support bandage 5 at the corresponding position.

[0058] In this embodiment, as Figure 4 As shown, the base plate 71 and guide wheel 4 are connected by the tension cable 72, and the connection between the tension cable 72 and the guide wheel 4 is located on the inner side of the seat frame 2. Therefore, when the guide wheels 4 on both sides rotate outward to stretch the support bandage 5, the seat plate will be dragged upward by the tension cable 72. At this time, the top of the support spring 73 will contact the bottom of the support bandage 5 to support the support bandage 5. Since the deformation of the support bandage 5 is consumed by the guide wheels 4 on both sides, the support spring 73 will be compressed at this time, further improving the support force for the sofa upholstery, so that the sofa forms a relatively firm state, which is suitable for members who need a firm sofa.

[0059] Conversely, when a member needs a soft sofa, the guide wheels 4 on both sides deflect inwards. At this time, the stretched support straps will loosen, and the support springs 73 will also stretch, making the sofa softer to suit members who need a soft sofa.

[0060] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the guide component 8 includes:

[0061] Multiple sliding rails 81 are provided and are fixedly installed on both sides of the inside of the sofa frame 1.

[0062] The sliding groove 82 is formed at both ends of the base plate 71, and the sliding rail 81 is inserted into the sliding groove 82.

[0063] In this embodiment, as Figure 5 As shown, the sliding rail 81 and the sliding groove 82 guide the base plate 71 when it moves up and down, improving the stability of the base plate 71 during sliding. The groove wall of the sliding groove 82 is provided with ball bearings to improve the smoothness between the base plate 71 and the sliding rail 81.

[0064] The implementation principle of the above embodiment is as follows: the drive component 6 drives the rotating shafts 3 on both sides to deflect at an angle, so that the two rotating shafts 3 rotate relative to each other. At this time, the guide wheels 4 on both sides can stretch or loosen the support bandage 5, so that the support force of the support bandage 5 can be changed accordingly, thereby adjusting the support force of the support bandage 5 on the sofa upholstery, thereby achieving the purpose of adjusting the softness and hardness of the sofa frame.

[0065] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
