Description

TECHNICAL FIELD

[0001] The utility model belongs to sunshade technical field, concretely relates to a winding type sunshade. BACKGROUND

[0002] Sunshade is a useful device for sheltering from the sun in summer, and its colorful appearance design has become a beautiful scenery in the street. The sunshades on the market generally occupy a large space, and while the sunshade effect is greatly improved, the inconvenience of disassembly is also increasingly obvious. Therefore, a telescopic sunshade emerges as the times require.

[0003] One of the categories is represented by the utility model with the patent application number CN201320850125.4 and the name "folding sunshade", which realizes the telescopic function through multiple hinged rods, and a roller is arranged at the hinge point on the same side to provide support for the hinged rod and reduce the friction between the hinged rod and the support surface. However, the biggest problem of this utility model is that the mechanical structure is relatively complex, and once the hinge points are rusted or damaged, the free telescopic function will be greatly reduced.

[0004] Another category is represented by the invention with the patent application number CN201310286546.3 and the name "winding type car sunshade", which relies on the up-down transmission umbrella gear to drive the winding umbrella gear to realize the rolling of the winding rod, and then makes the sunshade cloth wind around the peripheral surface of the winding rod. In addition to driving the winding umbrella gear to move, the up-down transmission umbrella gear can also realize the winding and unwinding of the sunshade cloth arm rod by applying tension to the sunshade cloth during the up-down movement along the threaded rod. It should be said that this invention is ingeniously designed, the force direction and transmission direction are changed multiple times by using the umbrella gear set, and the threaded connection and gear connection are relatively reliable, with high stability in operation. However, there are still some shortcomings. In the fully expanded state of the sunshade, if the maximum sunshade area is pursued, there is a contradiction between the angle between the sunshade cloth and the sunshade cloth arm rod and the height of the threaded rod: if the angle between the sunshade cloth and the sunshade cloth arm rod is small, the height of the sunshade cloth from the ground will be low, and accordingly, the height of the threaded rod can also be set relatively low, but the cost is that the sunshade cloth needs to exert a large force on the sunshade cloth arm rod, which may cause the sunshade cloth to tear; if the angle between the sunshade cloth and the sunshade cloth arm rod is large, the sunshade cloth only needs to exert a small force to make the sunshade cloth arm rod move, but the height of the threaded rod needs to be correspondingly increased to realize the winding of the sunshade cloth arm rod.

[0005] There is another kind of patent application number for CN201420161510.2, name for "a louver window with sunshade" as the representative, the working principle of the sunshade is used in the curtain, the sunshade cloth is provided with a pull rope and a spring on both sides, in normal use, the spring is in a natural state, the sunshade cloth is in an open state; when the sunshade cloth needs to be folded, only the pull rope needs to be pulled, because the spring is in an elongated state at this time, the pull rope should be fixed. The utility model needs to be improved, including: the required pull rope is longer and will produce friction with the sunshade frame, etc. After being pulled back and forth for many times, it is easy to break, which affects the use; according to the design, the same side of the sunshade cloth has a pull rope, that is, two pull ropes need to be pulled at the same time to ensure the normal use of the sunshade cloth, because the synchronism of pulling is difficult to guarantee, therefore, the sunshade cloth is more prone to skew in use, thereby greatly increasing the probability of part damage; using the tension spring can simplify the structure, but the tension spring has a certain length, which leads to the existence of gap between the sunshade frame and the sunshade cloth, and the sunshade effect is reduced.
