Abstract

Disclosed in the present invention is a zero-gravity leisure chair driven by human body power, comprising a base supporting assembly, a seat frame assembly, a pedal stretching assembly and a backrest. The pedal stretching assembly is centrally hinged to a first hinge point at the front end of the seat frame assembly and can extend or contract relative to the base supporting assembly; the backrest can be connected to the rear end of the seat frame assembly in a flipping and tilting manner relative to the seat frame assembly; moreover, an adjustment action for a zero gravity lying posture state is divided into two sections of driving actions; during driving of human body power, a zero gravity lying posture state can be adjusted by applying two small forces, respectively, so that convenient operation and high applicability are achieved, and a sitting-standing action is facilitated.

Abstract

A seat with an electric lifting function, the seat comprising a seat body (1), a base (2), and an electric lifting mechanism (3). The electric lifting mechanism (3) is connected between the seat body (1) and the base (2), and the electric lifting mechanism (3) comprises: a mounting seat (31), which is arranged on the base (2); two four-bar linkage mechanisms (32), which are arranged opposite each other and are connected between the mounting seat (31) and the seat body (1); a power rod (33), which is connected between the two four-bar linkage mechanisms (32); and a driving device (34), wherein two ends of the driving device (34) are respectively hinged to the mounting seat (31) and the power rod (33), such that the driving device (34) drives the two four-bar linkage mechanisms (32) to swing by means of the power rod (33) so as to drive the seat body (1) to lift between a low position and a high position, and the driving device (34) is located in an accommodating space, which is defined by the mounting seat (31), the two four-bar linkage mechanisms (32) and the power rod (33). In the seat, the electric lifting mechanism (3) is used to lift the seat body (1), so as to facilitate sitting height adjustment by a user and improve the user experience; and the electric lifting mechanism (3) has a simple and compact structure, such that the amount of space occupied is small.

Abstract

A structure for adjusting the seat inclination angle of a lounge chair, comprising: a seat frame assembly (1), a driving part, support legs, a pedal assembly (2), a plurality of seat frame connecting rods, and a plurality of pedal connecting rods. When a user needs to adjust a seat to a lying posture mode, the user operates the driving part, a first connecting rod mechanism acts, the seat frame assembly (1) drives a seat panel to rotate and incline close to the support legs, and pedals may be rotated and opened, facilitating the user to place the entire legs flat; when the user needs to adjust the seat to a sitting posture mode, the user operates the driving part to act reversely, so that an end of the seat panel close to the legs is lifted up relative to the ground, such that space between the end of the seat panel close to the legs and the ground is larger, enabling the pedals not to scrape the ground or the support legs when the pedals are being folded and stored, thus enhancing the safety performance; in addition, the relative angle between the seat frame assembly (1) and the support legs is adjusted by means of a second inclination angle driving structure, so that the seat frame assembly (1) drives the seat panel to be adjusted to a flatter angle, facilitating the user to sit and stand.

Abstract

A support structure and a seat, relating to the technical field of mechanical structures. The support structure comprises a seat frame assembly (11), a pedal assembly, and a motion linkage assembly (15). The support structure further comprises a first reset elastic member (16). The first reset elastic member (16) is disposed on the seat frame assembly (11) and connected to a motion drive assembly (14) or the pedal assembly. The first reset elastic member (16) applies a reset elastic force to the motion drive assembly (14), and directly or indirectly drives the pedal assembly to rotate relative to the seat frame assembly (11) to retract. According to the support structure and the seat, the first reset elastic member (16) is used to assist the pedal to retract, the force required for retracting the pedal assembly is reduced, and the retraction speed is high. The support structure and the seat have the advantages of convenience, labor saving, and rapidness.
