DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6 The shown embodiment is an integrally linked zero-gravity single chair functional frame, comprising a chair body 1, which is composed of a chair back 101, a seat 103 and armrests 102. The bottom sides of the chair back 101 are fixedly connected to the back of the armrests 102. The seat 103 is arranged between the bottoms of the armrests 102 and at the front end of the chair back 101. A hinge mechanism 2 is arranged at the bottom end of the chair back 101, and a motor 3 is arranged between the hinge mechanism 2 and the seat 103. The motor 3 drives the chair body 1 to adjust its angle by driving the hinge mechanism 2.

[0025] It should be noted that the backrest 101 and armrest 102 of the designed single chair are integrated into one, allowing the chair body 1 to tilt backward as a whole, achieving the zero gravity function while completely solving the safety hazard and improving the comfort of the single chair. The armrest 102, the backrest 101 and the seat 103 are linked to completely avoid the occurrence of various possible angles, thus effectively solving various safety hazards.

[0026] Specifically, a plurality of first-type ears 104 are arranged on both sides of the back of the seat 103 , and second-type ears 203 are arranged on both sides of the bottom end of the seat 103 and at one end close to the hinge mechanism 2 , and the top of the second-type ears 203 is fixedly connected to the top of the seat 103 .

[0027] It should be noted that the designed seat 103 is hinged to the backrest 101 and the hinge mechanism 2 through lifting ears, so that the whole single chair can be linked to each other. When the body drives the backrest 101 to move, the seat 103 and the hinge mechanism 2 can be linked through the lifting ears to achieve angle deviation, giving the user a zero-gravity experience.

[0028] Specifically, the hinge mechanism 2 includes: a hinge fixing member 201, both sides of which are hinged to the outer wall of the second type of lifting ear 203; a hinge rocker member 202, both sides of which are hinged to the top of the hinge fixing member 201, and a plurality of first type lifting ears 104 are hinged to the front end of the chair back 101 through studs.

[0029] It should be noted that the hinge mechanism 2 combined with the motor 3 to push the bearing forward is the simplest and most direct way to achieve the reclining and forward tilting of the single chair. At the same time, the motor 3 pushing the bearing in the groove reduces friction, saves effort and is noiseless. The hinge fixing part 201 and the hinge rocker part 202 are hinged, and their special shape can achieve zero-gravity forward and backward movement. The notches at both ends are used to connect the bearing sliding to ensure the consistency of the movement direction of the motor 3, thereby minimizing the friction noise and the deviation and force of the motor 3 during movement.

[0030] Specifically, a raised sliding structure 204 is provided at the front end of the hinge fixing part 201, and the front end of the motor 3 is hinged to the inner wall of the sliding structure 204. The sliding structure 204 is used to cooperate with the motor 3 to drive the hinge rocker member 202 to swing. The back ends of both sides of the hinge rocker member 202 are hinged to the bottom ends of both sides of the second type of lifting ears 203. The bottom of the motor 3 is hinged to the inside of the hinge fixing part 201 and is located close to one end of the sliding structure 204. The middle part of the hinge fixing part 201 is sleeved with a base 4, and the front end of the seat 103 is hinged with a spring pad 5.

[0031] It should be noted that the designed base 4 refers to model SG018, and mechanical conduction technology is integrated into the base 4. The height can be adjusted according to the body height and the angle position can be locked. It adopts high-load-bearing steel feet, which are stable, not easy to shake and have strong pressure resistance. The designed elastic feet are connected to the seat 103 through a hinge. When the motor 3 moves, the hinge and hinge mechanism 2 are linked, and the elastic foot pad 5 is upward to realize the zero gravity function.

[0032] Working principle of this utility model:

[0033] The designed zero-gravity single chair integrates the armrest 102 and the backrest 101. When the chair body 1 tilts backward as a whole, the backrest 101 and the armrest 102 are linked to each other. The base 4 is designed with a first type of lug 104 and a second type of lug 203, and the entire single chair is connected by studs to support the movement of the single chair. When the zero-gravity single chair is used, the motor 3 is started, and the front end of the motor 3 is hinged in the groove of the hinge fixing part 201 to push the hinge rocker part 202 to realize the reclining and forward tilting of the backrest 101. The bottom end of the backrest 101, the seat 103 and the middle of the hinge mechanism 2 are all hinged. According to the principle of the hinge mechanism 2, it makes it more labor-saving and smoother when the motor 3 moves.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
