Preferably, the front ends of the stretching frame, namely the front ends of the two movable rods in the first group of movable cross rods, are commonly connected with a driving device.

Preferably, the driving device comprises a threaded shaft, one end of the threaded shaft is connected with a motor, the front ends of two movable rods in the first group of movable cross rods are respectively provided with a sliding block, and the sliding blocks are sleeved on two sides of the threaded shaft.

The first fixed block and the second fixed block are additionally arranged on the first hinge point and the second hinge point, the first cross rod and the second cross rod are sleeved on the first hinge point and the second hinge point, when the extension frame extends, namely, the two movable rods of the movable cross rod are movably and rotatably extended along the connecting point of the movable cross rod, all the movable rods extend and move forward, meanwhile, the first sliding groove and the second sliding groove are used as sliding rails, the first fixed block and the second fixed block are used as sliding points, the tail ends of the first cross rod and the second cross rod are driven to extend to two sides respectively, and then the awning cloth connected to the tail ends of the first cross rod and the second cross rod is driven to extend to two sides, so that the sunshade area of the sunshade is greatly increased, the occupied space when the sunshade is reduced, the sunshade is convenient to carry, can be placed in a car trunk, can be placed in a ship body or other vehicles, and is taken out to be used conveniently when needed. The overlapping of first horizontal pole and second horizontal pole sets up, and the setting of first spout and second spout makes the sunshade be more steady no matter draw in or extend, can not occupy extra space, when extending and shrink, can not mutual interference for whole extension frame compacter coordination. When the extension frame is completely folded, the first fixing block and the second fixing block are respectively positioned at two ends of the first sliding groove and the second sliding groove, so that the lengths of the first sliding groove and the second sliding groove are most reasonable, and the lengths of the first transverse rod and the second transverse rod can be utilized to the greatest extent. The mode of driving the extension frame can be realized by adopting manpower or electric power, and the extension frame can be additionally arranged according to actual requirements.

Detailed Description

The technical solution of the present invention will be further described with reference to fig. 1 to 7, but is not limited to this description.

The multipurpose expansion sunshade comprises an expansion frame 1, wherein the expansion frame 1 comprises a plurality of groups of movable cross rods which are sequentially hinged end to end, and each movable cross rod comprises two movable rods 2 with middle points correspondingly hinged; in the extension frame 1, there are two groups of hinge points formed by hinging the movable cross rod in sequence, wherein the two groups of hinge points comprise a first hinge point 3 positioned at the left side of the extension frame 1 and a second hinge point 4 positioned at the right side of the extension frame 1, a first fixed block 5 is arranged on the first hinge point 3, and a second fixed block 6 is arranged on the second hinge point 4; a first cross rod 7 is arranged on each first fixed block 5, a first chute 8 is hollowed out on each first cross rod 7, the inner end of each first chute 8 is close to each first fixed block 5, and the outer end of each first chute 8 is nested on the corresponding second fixed block 6; a second cross rod 9 is arranged on each second fixed block 6, a second chute 10 is hollowed out on the second cross rod 9, the inner end of the second chute 10 is close to the second fixed block 6, the outer end of the second chute 10 is nested on the first fixed block 5, and the second cross rod 9 is positioned above the first cross rod 7; the stretching frame 1 is sleeved with a piece of shed cloth 11, and the connection point of the shed cloth 11 and the stretching frame 1 is located at the outer ends of the first cross rod and the second cross rod. Of course, the first cross bar 7 and the second cross bar 9 may be installed in a manner that the first cross bar 7 is up and the second cross bar 9 is down, and the principle and structure are the same as those of the above scheme.

The front ends of the extension frame 1, i.e. the front ends of the two movable bars 2 in the first set of movable cross bars, are commonly connected with a driving device. The driving device comprises a threaded shaft 12, one end of the threaded shaft 12 is connected with a motor 13, the front ends of two movable rods 2 in the first group of movable cross rods are respectively provided with a sliding block 14, and the sliding blocks 14 are sleeved on two sides of the threaded shaft 12. The driving device can enable the sunshade to automatically extend and retract, thereby saving manpower. When the motor 13 is started, the threaded shaft 12 rotates to drive the two sliding blocks 14 to move relatively, so that the movable rod 2 is driven, and the whole extension frame 1 is opened.

The sunshade can be particularly applied to vehicles such as automobiles, most of automobiles are exposed to sunlight when the weather is hot and the sunlight is large, the temperature in the automobiles can rapidly rise soon, great potential safety hazards exist, and the automobiles generally need to open the doors before entering the automobiles for starting, and air conditioning is carried out to cool.
