The front or rear cross supporting rod assembly includes two front cross supporting rods. The seat rods are connected to the front legs, rear legs and upright poles. The backrest rods are connected to the rear legs. The upright poles are movably connected to the front legs.

PROBLEM TO BE SOLVED: To provide a foldable chair which can be folded into a small size in a chair of an L-shaped frame structure. SOLUTION: The foldable chair is provided with: a vertical frame member 10 extending in a vertical direction; a seat plate 50 supported at the intermediate position of the vertical frame member 10; and a base frame member 30 whose front end is connected turnably to the lower end of the vertical frame member 10. The base frame member 30 selectively takes an opening state position extending on a floor surface with a prescribed angle to the vertical frame member 10 extending in the vertical direction or a folded state position extending along the vertical frame member 10 at a position in front of the vertical frame member 10.

The hinge structure is pivotally connected to the connecting portion and the first display screen portion, respectively. The computer mainframe is slidably disposed on the connecting portion. The computer mainframe is slidable relative to the first display screen portion for alternatively changing arrangement orientations of the computer mainframe relative to the first display screen portion.

The invention relates to a modular large-array surface radar antenna mechanism. The modular large-array surface radar antenna mechanism comprises a first longitudinal rod and two second longitudinal rods, wherein a lead screw driving mechanism is arranged on the first longitudinal rod, the two second longitudinal rods are symmetrically arranged at two sides of the first longitudinal rod and are connected with the lead screw driving mechanism via a first connection rod, the first longitudinal rod is connected with the first connection rod via a second connection rod, and a plurality of oscillators are arranged on both of the first longitudinal rod and the two second longitudinal rods. In the antenna mechanism, by combination of the lead screw driving mechanism, the first connection rod andthe second connection rod, folding and unfolding of the antenna mechanism can be achieved, the antenna mechanism has the characteristics of large unfolding size and small folding size, the large powerrequirement of radar when the antenna mechanism is unfolded can be met, the requirement on high maneuverability and transportation performance of the radar when the antenna mechanism is folded is met, meanwhile, an antenna array surface with a relatively large size can be formed by combining a plurality of antenna mechanisms.

The invention relates to a luggage cart type front drive folding tricycle which comprises a front wheel, a handlebar, a front fork tube, a fork tube, a transverse beam, a saddle, a rear wheel rack, rear wheels and pedals, wherein the front wheel is a large wheel, and the rear wheels are small wheels; a folding device is directly arranged at the upper part of the front fork tube; the folding device is hinged with the transverse beam; the transverse beam is of a double-tube structure; the arc-shaped forked rear wheel rack is directly and fixedly arranged in the same plane at the lower end of the transverse beam; two lower ends of the rear wheel rack are fixedly arranged on the axis of the rear wheels; a fork rack is fixedly arranged on the rear wheel rack; a positioning support leg is fixedly arranged downwards at the middle part of the fork rack; and the positioning support leg and the two rear wheels form a stable plane when the transverse beam is upright. The folding tricycle disclosed by the invention is simple in structure, convenient and rapid to fold, high in riding efficiency and high in stability, a luggage cart can be formed after the tricycle is folded up, the application is widened, and the folding tricycle is small in size and convenient to store.

The invention discloses a stretching mechanism-supported double-side array large-area flexible solar cell wing. The stretching mechanism-supported double-side array large-area flexible solar cell wingcomprises a lifting mechanism, a stretching mechanism, two flexible solar cell arrays, pressing and releasing devices and box body unfolding and locking mechanisms; two ends of the top of the stretching mechanism are respectively connected with the two flexible solar cell arrays, and the bottom of the stretching mechanism is connected with the lifting mechanism; in an initial state, the two flexible solar cell arrays are symmetrical about the stretching mechanism; the stretching mechanism and the flexible solar cell array are each provided with a plurality of pressing points; and the pressingand release devices are arranged at the positions of the corresponding pressing points to press the stretching mechanism and the flexible solar cell arrays; the box body unfolding locking mechanismsare arranged at the connecting positions of the two ends of the top of the stretching mechanism and the first flexible solar cell array and the second flexible solar cell array and are used for unfolding the flexible solar cell arrays towards two sides in place and locking the flexible solar cell arrays. The stretching mechanism-supported double-side array large-area flexible solar cell wing has the advantages of small folding envelope, large unfolding area and stable unfolding configuration, and is suitable for a high-power spacecraft platform.

The invention relates to a general-purpose aviation folding bicycle, which includes a main support, and the main support includes two main columns and a plurality of intermediate folding areas erected between the two main columns that can be folded into the plane between the two main columns. The flap also includes two side brackets located on both sides of the main bracket. The top of the side bracket is connected with a foldable side flap. The side bracket includes a side column and several cross beams erected between the side column and the main column. One end of the beam is fixed on the side column, and the other end of the beam is hinged on the main column, which has the degree of freedom to fold the side bracket around the main column; the present invention provides a general-purpose aviation folding bike, which ensures the reliability of folding and the stability of the car body structure. compactness.

A moving carrier is disclosed. A lower-frame assembly includes a first moving member disposed on the guiding member, a second moving member disposed on the guiding member, an elastic member disposed corresponding to the guiding member, and a third moving member disposed on the second moving member. A transmitting member of a front-wheel assembly has a guiding groove. One end of the third moving member is disposed in the guiding groove. When the first moving member moves along the guiding member, the first moving member enables the elastic member to store a first energy. When the elastic member releases the first energy, the second moving member drives the third moving member to move and the third moving member pushes the guiding groove to move, so that the transmitting member can drive the front-wheel frame to move toward the lower-frame assembly.

The invention discloses a light vehicle and a folding mechanism thereof. The light vehicle comprises push handle upper tubes, push handle lower tubes, push handle seats, side handrails, swinging rods, rear wheel brackets, rear wheel seats and front wheel brackets, which are symmetrically arranged on the left and right sides, wherein the swinging rods, the side handrails, the rear wheel brackets and the push handle seats form four-point mechanisms; swinging rod mechanism consisting of the front wheel brackets and lower swinging rods mutually form a folding mechanism; the swinging rods are connected with the rear wheel brackets through small connecting rods; and the small connecting rods can drive sliding connecting rods, which are arranged on the rear wheel brackets in a sliding way, to move and drive the rear wheel brackets to be folded. The invention is advantaged in that the whole frame are folded under the driving of the four-point mechanisms, which include the swinging rods, the side handrails, the rear wheel brackets and the push handle seats, and the swinging rod mechanisms, which include the front wheel brackets and the lower swinging rods; rear wheels of the vehicle are folded inwards during folding; the folding process is convenient and can be operated by single hand; the folding dimension is reduced; and the folded vehicle can also self-stand so that the folded vehicle is convenient to store and the storage space is saved.
