Abstract
A framework for a car sunshade and the car sunshade. The framework comprises a support frame (1) capable of being placed on a car roof. Four corners at the front, rear, left and right sides of the support frame (1) or two cornersAppl at the front part of the support frame (1) are provided with projecting positioning posts (2). Each positioning post (2) is provided with several ribs (3) that can rotate around the axial line of the positioning post (2) and fan out to form fan-like surfaces upon rotating toward the outer edge of the support frame (1). The ribs (3) are arranged on the positioning posts (2). When sunshade cloth (7) is arranged on the ribs (3), the ribs (3) rotate about the center line of the axial lines of the positioning posts (2) and fan out in a fan-like formation upon rotating toward the outer edge of the left and right sides of the support frame (1). Sunshading is realized by the formation of fan-like areas projecting outward from the support frame (1). Therefore, the overall structure is very simple, the manufacturing is convenient, and the production cost is low.

DETAILED DESCRIPTION OF THE DRAWINGS
[0031] The following is a specific explanation of the present invention's technical solutions employing embodiments and referring to the attached figures.
[0032] Embodiment 1: See FIGS. 1 and 2; a car sunshade framework, which includes a support frame capable of being placed on a car roof 1, where support frame 1 is rectangular and can be mounted on the roof of an ordinary sedan. The four corners at the front, rear, left, and right sides of support frame 1 are provided with projecting positioning posts 2, and positioning posts 2 are arranged in a rectangle. Positioning posts 2 are 5 mm distant from the edge of support frame 1, and each positioning post 2 is provided several ribs 3 that can rotate around the axial line and fan out to form fan-like surfaces upon rotating toward the outer edge of the support frame 1. Ten ribs 3 are provided in the figure. Of course, the actual number of ribs is not restricted to ten, as long as they can extend to form a fan-like surface. The ribs are arranged on the positioning posts. When sunshade cloth is arranged on the ribs, the ribs rotate about the center lines of the axial lines of the positioning posts, and fan out in a fan-like formation upon rotating toward the outer edge of the left and right sides of the support frame. Sunshading of the two sides, front, and back of the car is realized by the formation of fan-like areas projecting outward from the support frame. The overall structure is consequently very simple, manufacturing is convenient, and production cost is low.
[0033] See FIGS. 1, 2, and 3; the upper and lower layers of the ribs 3 are arranged in an overlapping fashion, where the upper and lower ribs 3 can rotate relative to each other to form an included angle, and the spaces between ribs are provided with a linkage mechanism used to drive the rotation of adjacent ribs 3. The linkage mechanism provided between the upper and lower ribs causes the ribs to effectively achieve extension and retraction, and it is only necessary to provide an overall source of motive power to effect the rotation of the uppermost ribs. Retraction is convenient, and is readily subject to automatic operation. The linkage mechanism may consist of small sections of cord or cloth strips, and may also be realized by providing pieces of cloth in the space made by the included angle after this included angle has been formed by the upper and lower ribs.
[0034] See FIGS. 1, 3, and 6; the ribs 3 are formed by rotating elements 31 and support rods 32, where the foregoing linkage mechanism consists of pairs of connecting posts 4 and connecting slots 5 respectively disposed on the mating surfaces of adjacent rotating elements 31, the tops of the connecting posts 4 extend into the connecting slots 5 and can rotate within the connecting slots 5 with the rotation of the rotating elements 31, and both ends of the connecting slots 5 are provided with separating surfaces 51 and 52 preventing the connecting posts 4 from continuing to rotate in the connecting slots 5. The connecting posts and connecting slots are employed as a linkage mechanism, and the tops of the connecting posts extending into the connecting slots will rotate in the connecting slots with the rotation of the rotating elements. When extending, after the connecting posts within the connecting slots have rotated outward a certain angle, the separating surfaces of the outer ends of the connecting posts and connecting slots will be in contact, causing the upper and lower ribs to individually, jointly extend in rotating fashion, which enables the ribs to extend in a smooth and stable manner. Furthermore, when the ribs retract, after the connecting posts have rotated inward in the connecting slots a certain angle, the separating surfaces of the inner ends of the connecting posts and connecting slots will be in contact, causing the upper and lower ribs to individually, jointly retract in rotating fashion, enabling the ribs to retract quickly and effectively.
[0035] See FIGS. 1, 2, and 7; the ribs 3 include fixed ribs 3a that are fixed relative to the support frame 1, two or more driven ribs 3b located above the fixed ribs 3a and set over the positioning posts 2 in so that they are able to rotate, and driving ribs 3c located above the driven ribs 3b. The ribs consist of fixed ribs, driven ribs, and driving ribs, where the driving ribs rotate driven by an externally connected power source, and cause the driven ribs to rotate. Furthermore, since the fixed ribs are disposed so as to be fixed and unmoving relative to the support frame, the fixed ribs will not rotate with the rotation of the driven ribs above them, which causes the spaces between the ribs to form a stable fan-shaped sunshade surface after extension of the ribs. Furthermore, when retracting, the ribs can fully retract above the fixed ribs after the ribs have rotated in an inward direction. Retraction effectiveness will be good, it is only necessary to effect the rotation of the driving ribs to realize the extension of all the ribs, and the sunshade can readily be automatically operated.
[0036] See FIGS. 1, 2, and 7; the positioning posts 2 and support frame 1 are conjoined, and driving ribs 3c is placed on positioning post 2 so that it can rotate. When the positioning posts and support frame are fixed, the driving ribs can be freely placed on the positioning posts and thereby allow rotation about the positioning posts, achieving structural simplicity and convenient assembly. Of course, as an equivalent scheme, positioning posts 2 can be disposed on support frame 1 so that they can rotate, and driving ribs 3c and positioning posts 2 can be conjoined to realize rotation.
[0037] See FIG. 6; the separating surfaces of connecting post 4 and connecting slot 51 are mutually corresponding. Connecting post 4 is located to the front and above separating surface 51 in the connecting slot, allowing it to mate with separating surface 51. The side wall of connecting post 4 on the same side as separating surface 51 corresponds with separating surface 51 in the upward and downward directions. The retracted volume will be small since the ribs can retract fully during retraction.
[0038] See FIGS. 1 and 7; fixed ribs 3a face toward the interior of support frame 1, the included angle between fixed ribs 3a and the left and right edges of support frame 1 is 40°, the included angle between adjacent ribs 3 when extended is 35°, and the maximum angle of the fan-like surface formed by ribs 3 when extended is 315°. Accordingly, when driving ribs 3c rotate past the front and rear edges of support frame 1, they will rotate into the interior of support frame 1, and ribs 3 therefore completely cover the sides and corners of the support frame when extended, providing effective sunshading. Of course, fixed ribs 3a can be arranged parallel to the left and right edges of support frame 1. At that time, as long as the maximum angle of the fan-like surface formed by ribs 3 when extended is 270°, the fan-like surface can realize complete covering of the sides and corners of the support frame.
[0039] See FIG. 1; the difference between one-half the distance between right and left positioning posts 2 on support frame 1 and the length of ribs 3 is 3 mm. During the process of extending the ribs, when the ribs on the right and left sides rotate until they are parallel with the front and rear edges of the support frame, a gap remains between the two facing ribs. Accordingly, there will be no collisions when the right and left ribs are extended, which will facilitate complete extension of the ribs. Furthermore, the length of this gap is set as less than 30 mm, causing the gap created in the center of the front and rear sunshading areas to be small, and ensuring good sunshading effectiveness. By the same principle, the difference between one-half of the distance between the front and rear positioning posts 2 on support frame 1 and the length of the ribs 3 is 0-15 mm.
[0040] See FIG. 4; connecting slots 5 are arranged in a circular arc with positioning post 2 at their center. The connecting slots are arranged in a circular arc the positioning posts at their center, and the shape of the connecting slots can mutually accommodate the path of motion of the connecting posts. Accordingly, the connecting posts and connecting slots will have a good fit, enabling smooth rotation.
[0041] See FIGS. 1 and 7; support frame 1 is provided with fixed, projecting limit posts 6 serving to prevent the rotation of the driving ribs 3c, and the limit posts 6 are located on the inner side of the fixed ribs 3. When the driving ribs rotate and extend outward to the right and left from the interior of the support frame, they will rotate past the front and rear edges of the support frame to the interior of the support frame. The limit posts are disposed above the support frame and on the inner side of the fixed ribs; this ensures a good ability to limit and fix the driving ribs, and facilitates structural stability. See FIGS. 1 and 7; support rods 32 are in a parallel arrangement with support frame 1, facilitating the extension and retraction of the support rods.
[0042] FIG. 8 is a structural schematic diagram of an extended car sunshade comprising the car sunshade framework in this embodiment with sunshade cloth mounted on it. As shown in FIG. 8, sunshade cloth 7 consists of 4 pieces on the front, rear, right, and left; the 4 pieces of sunshade cloth 7 are respectively fixed by the ribs 3 disposed on the front, rear, right, and left portions of support frame 1, and form a fan-like surface when ribs 3 are fully extended. Sunshade cloth 7 covers the fan-like surface to form a fan-like sunshading surface, which possesses good sunshading effectiveness. When sunshade cloth 7 is fixed on the ribs, the ribs rotate about the center lines of the axial lines of the positioning posts, and fan out in a fan-like formation upon rotating toward the outer edge of the left and right sides of the support frame. Sunshading is realized by the formation of fan-like areas projecting outward from the support frame. The overall structure is consequently very simple, manufacturing is convenient, production cost is low, extension and retraction are convenient, and the sunshade is easy to operate automatically.
[0043] Embodiment 2: See FIG. 9; in the car sunshade framework, which includes a support frame capable of being placed on a car roof 1, support frame 1 is rectangular and can be mounted on the roof of an ordinary pickup or small van. The two front corners of support frame 1 are provided with projecting positioning posts 2, and positioning posts 2 are provided with several ribs 3 that can rotate around the axial line and fan out to form fan-like surfaces upon rotating toward the outer edge of the support frame 1; other aspects are identical with those in embodiment 1.
[0044] See FIG. 10, which shows a structural schematic diagram of an extended car sunshade comprising the car sunshade framework in this embodiment with sunshade cloth mounted on it. As shown in FIG. 8, sunshade cloth 7 consists of 2 pieces on the left and right; the 2 pieces of sunshade cloth 7 are respectively fixed by the ribs 3 disposed on the left and right portions of support frame 1, and form a fan-like surface when ribs 3 are fully extended. Sunshade cloth 7 covers the fan-like surface to form a fan-like sunshading surface, which possesses good sunshading effectiveness.
[0045] Various modifications of the present invention are obvious to any person skilled in this technical field; these modifications cannot be considered outside the scope of the present invention. All modifications obvious to any person skilled in this technical field are included within the scope of the current claims.
