Description

Technical Field

[0001] The invention relates to the technical field of leisure sofa furniture manufacturing, in particular to an upgraded and reinforced zero-gravity leisure sofa. Background Art

[0002] Leisure sofas are not unfamiliar to us, and they have a variety of functions, including the reclining function of the backrest, the forward extension function of the seat, and the folding and extending function of the footrest. Combined with the backrest, seat and footrest, the bottom of the leisure sofa uses a matching chair frame mechanism to enable the leisure sofa to achieve a reclining angle of 0°~180°, and the maximum reclining angle is 180°, which can only be used for lying down during rest. Nowadays, consumers have higher and higher requirements for the structural design and functional use of seats, and are not satisfied with the current functions of leisure sofas. If you want to achieve a more comfortable reclining angle, let the whole body be in a completely relaxed state, and let the human body release stress, you can design and manufacture an upgraded and enhanced zero-gravity leisure sofa.

[0003] The invention disclosed in application number: 201721605286.1 is realized by the following technical scheme: a manual zero-gravity chair is disclosed, including a seat frame and a rear frame, an elastic seat cushion and an elastic backrest, and the seat frame includes a left armrest and a right armrest, a support beam, an intermediate frame, a front frame, a rear frame, a reclining lock, a cylinder, a piston rod, a switch, and a V-shaped cantilever. A combined structure in which an elastic seat cushion is fixedly sleeved on the outside of the seat frame is adopted, and the rotation of the front frame and the rear frame can be freely controlled by manually twisting the reclining lock and the manual control switch, respectively, so that the user can freely switch between sitting and lying positions as needed, thereby improving the convenience of use and the flexibility of operation; and the V-shaped cantilever provided in the seat frame improves the reliability and stability of the seat frame formed by the left armrest, the right armrest, the front frame, the intermediate frame, and the rear frame during long-term use, and makes the installation, disassembly, maintenance and other operations more convenient.

[0004] The manual zero-gravity chair has a clever structural design and strong practicality, but the zero-gravity function of this zero-gravity chair is still achieved through manual control, which is relatively troublesome to operate. In addition, the footrest cannot be extended and retracted independently, and must operate together with the backrest and seat cushion. There are certain limitations. When the chair is laid down, it does not reach the angle of top-heavy weightlessness. Summary of the invention

[0005] In view of the above-mentioned existing zero-gravity chairs having difficulties in manual operation, complex structures, inability to operate footrests independently, and failure to reach the reclining angle required for zero gravity, the present invention proposes an upgraded and enhanced zero-gravity leisure sofa.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an upgraded and reinforced zero-gravity leisure sofa, comprising a zero-gravity upgrade mechanism, an electric component, a chair frame, a seat frame, an armrest, and a footrest. The zero-gravity upgrade mechanism is composed of an arc-shaped main part, an arc-shaped slide member, and a sliding mechanism. The upper end of the arc-shaped main part is fixed to the inner side of the armrest baffle through the main load-bearing rod through the first bolt, and the middle of the arc-shaped main part is a hollow shape. An arc-shaped slide member is fixed at the bottom of the arc-shaped main part, and the two ends of the arc-shaped slide member are fixed on the arc-shaped main part, and the arc-shaped slide member is flat. The gap formed between the arc-shaped main part and the arc-shaped slide member is used as a slide. The sliding mechanism includes a sliding member, a roller, and a second bolt. The sliding mechanism is fixed to the armrest baffle by the second bolt, and the roller is fixed to the armrest baffle by passing through the sliding member. The roller is composed of a rivet, a sleeve, and a gasket. The rivet is placed at the front end, the sleeve is inserted in the middle of the rivet, and the gasket is inserted at the rear end. The distance between the sleeve and the gasket clamps the arc-shaped slide member and allows it to slide. The sliding mechanism slides left and right in the slide as the electric component, chair frame, and seat frame operate. The zero-gravity upgrade mechanism is fixed to the armrest baffle through the main load-bearing rod of the seat frame, and the rear end of the seat frame is fixed to the bottom end of the chair frame and the front end of the seat frame is fixed to the footrest through the first bolt in the bolt column, so that the footrest can move up and down. The electric component includes a switching power supply, a first motor, and a second motor. The rear end of the first motor is fixed to the middle of the rear end of the seat frame, and the top end is fixed to the chair support rod. The front end of the second motor is fixed to the front end of the footrest, and the rear end is fixed to the bottom of the front end of the seat frame. When the switching power supply is started, the front end of the first motor is retracted, driving the seat frame, chair frame, and zero-gravity upgrade mechanism to operate simultaneously, so that the seat frame and chair frame reach a certain reclining angle. The zero-gravity upgrade mechanism, the electric component, the chair frame, the seat frame, the armrest, and the footrest constitute an upgraded and enhanced zero-gravity leisure sofa.

[0007] The independently developed innovative structures in the present invention are as follows: (1) The zero-gravity upgrade mechanism is composed of an arc-shaped main part, an arc-shaped slide groove part, and a sliding mechanism. The sliding mechanism is composed of a sliding part, a roller, and a second bolt. The design of the sliding mechanism plays a key role. The sliding mechanism can slide arbitrarily in the slide groove formed after the arc-shaped main part and the arc-shaped slide groove part are fixed. When the switch power is started, the front end of the first motor is retracted, driving the seat frame, the chair frame and the zero-gravity upgrade mechanism to run at the same time, so that the seat frame and the chair frame reach a certain reclining angle. After operating the second motor button on the switch power, the front end of the second motor is extended to the longest, and the footrest can be opened to the maximum angle. When the front end of the second motor is retracted to the shortest, the footrest can be folded to the minimum angle at the bottom without taking up space. The zero-gravity upgrade mechanism at both ends of the seat frame is fixed on the main load-bearing rod of the seat frame. When the first motor and the second motor are operating at the same time, the sliding mechanism on the zero-gravity upgrade mechanism slides flexibly in the slide groove, so that the zero-gravity upgrade mechanism, driven by the first and second motors, enables the leisure sofa to lie down with the chair frame and the seat frame and footrest tilted up, so that the consumer's body gravity is evenly distributed, allowing the body to be in a state of natural comfort and release of physical and mental stress; (ii) The first motor and the second motor are also known as electric push rods and linear drives, which are composed of drive motors, reduction gears, screws, nuts, etc. They are mainly a new type of linear actuator composed of mechanisms such as motor push rods and control devices, which enable the electric push rods to move back and forth within a certain range of travel, and can achieve remote control and centralized control.

[0008] As a preferred embodiment of the above technical solution, the armrest is composed of an armrest baffle, an upper armrest shelf, a front support, a rear support, and a bottom support. A soft armrest bag can be placed on the outer side of the upper armrest shelf and the armrest baffle.

[0009] As a preferred embodiment of the above technical solution, the zero-gravity upgrade mechanism is fixed on the armrest baffle, one on each side.

[0010] As a preferred embodiment of the above technical solution, an adjustable headrest is fixed to the upper stopper of the seat frame, and the adjustable headrest is fixed by a connecting member.

[0011] As a preferred embodiment of the above technical solution, the armrest upper shelf is placed at the uppermost end, the front support and the rear support are respectively fixed to the front and rear ends of the armrest baffle, and the bottom support is fixed to the lowermost end of the armrest board.

[0012] The invention independently develops the armrest structure: the armrest is composed of an armrest baffle, an upper armrest shelf, a front support, a rear support, and a bottom support. The upper armrest shelf is placed at the top, the front support and the rear support are respectively fixed to the front and rear ends of the armrest baffle, and the bottom support is fixed to the bottom of the armrest baffle. The outer side of the upper armrest shelf and the armrest baffle can be touched by the armrest soft bag, and the inner side of the armrest baffle can fix the zero gravity upgrade mechanism hidden inside the armrest, which is both beautiful and practical.

[0013] As a preferred embodiment of the above technical solution, there are several buckles on the outer side of the armrest baffle for fixing the armrest soft bag.

[0014] The present invention has the following beneficial effects:

[0015] 1. The zero-gravity upgrade mechanism used in the present invention enables the leisure sofa to lie down with the chair frame driven by the first motor and the second motor, and the seat frame and the footrest to tilt up, so that the gravity of the consumer's body is evenly distributed, so that the body is in a state of natural comfort and release of physical and mental stress. The structure is novel and concise, conforming to the ergonomic design, and the footrest can be retracted to the bottom of the seat frame driven by the second motor to save space;

[0016] 2. The armrest upper shelf and the outer side of the armrest baffle of the armrest structure independently developed by the present invention can be soft-padded, and the inner side of the armrest baffle can well hide the zero-gravity upgrade mechanism inside the armrest, which is both beautiful and practical.
