Description

Technical Field

[0001] The utility model belongs to the field of automobile covers, in particular to a retractable automobile sunshade cover. Background Art

[0002] When the temperature of a car is between 38 and 40 degrees in the hot summer, it is parked in the open air and exposed to the sun, causing the temperature inside the car to reach more than 60 degrees. This will cause great damage to the plastic parts and electronic components of the dashboard in the car for a long time. The high temperature of more than 60 degrees is unbearable for the passengers. For this reason, people have manufactured a variety of car sun protection products. There are mainly three categories: 1. Curtains attached to the car windows to prevent sunlight from entering the car; 2. Manual or remote-controlled electric sunshades fixed on the top of the car similar to umbrella structures; 3. Various types of awnings. The disadvantages of the above three types of technologies are analyzed as follows: The first type can only block sunlight from entering the car through the windows, although it has a certain cooling effect. However, since the car's shell is made of metal, the heat absorbed by the metal after being exposed to the sun for a long time in summer is transferred to the car through conduction, and the temperature inside the car still reaches about 50 degrees, making it impossible for drivers and passengers to enter the car directly; the second type of manual awnings are difficult to fold, unfold and fix, and have a complex structure. Although the electric remote control is much more convenient in folding and unfolding, the common disadvantage of both is poor wind resistance, and can only cover part of the roof. The sun will still shine into the car through the window, and the sunshade and cooling effect is the same as the first type; the third type of sunshade and cooling effect is significantly better than the first two types. When the temperature is between 38 and 40 degrees, the temperature inside the car is between 40 and 42 degrees after about three hours of sun exposure, which is acceptable to the driver and passengers. However, its folding and unfolding are complicated, and some require two people to cooperate. The wind resistance is poor. It is a sweaty and hard work to fold and unfold such a sunshade in the hot summer under the scorching sun. Except for the first type, which does not take up much space when stored in the car, the other two types occupy space in the car, affecting the storage space in the car, and are costly. Utility Model Content

[0003] The purpose of the utility model is to overcome the problems of the prior art and provide a car fast-folding and unfolding shared sunshade that is quick to fold and unfold, has good sunshade and sun protection effects, has good wind resistance, and does not require the car owner to prepare it himself. It has a simple structure and low cost. In order to achieve the above purpose, the utility model adopts the following technical solutions.

[0004] A car fast-folding and unfolding shared sunshade, which is composed of a fan-shaped sunshade frame formed by hingedly connecting more than three door-shaped cloth frames in two frame hinge seats and a sunshade cloth positioned on the fan-shaped sunshade frame, characterized in that a pair of floor-standing door-shaped cloth frames that touch the ground after unfolding are both positioned with fulcrum rod guide rails on the left and right sides, each fulcrum rod guide rail is provided with a guide rail groove along the length direction of the side, a fulcrum rod is positioned on each guide rail groove by a quick-locking bolt assembly, and the fulcrum rod can be loosened along the length direction of the guide rail groove by loosening the bolt assembly Move back and forth and rotate 360° around the bolt axis. When the entire sunshade is fully unfolded, loosen the bolt assembly and rotate the four fulcrum rods toward the inside of the chassis. At the same time, move the four fulcrum rods along their respective guide rail grooves until they are close to the four wheels. Then adjust the axis of the fulcrum rods until they are roughly parallel to the axes of the four wheels. Finally, tighten the bolt assembly. The ends or both sides of the pair of floor-standing door-shaped fabric frames corresponding to the positions of the adjacent door-shaped fabric frames are positioned with length-adjustable quick-tightening belts. The fulcrum rods are adjusted into place After locking, all quick tightening belts are tightened. At this time, the floor-standing door-shaped cloth frame and its adjacent door-shaped cloth frame are moved closer to each other. The floor-standing door-shaped cloth frame drives four fulcrum rods to press against four tires and the sunshade cloth is tightened at the same time, so that the entire sunshade cover is firmly fixed on the body by the weight of the vehicle body; the two sides of the above-mentioned floor-standing door-shaped cloth frame near the end are hinged with folding hooks, and the two sides of the other floor-standing door-shaped cloth frame near the end are provided with hook nails, so that the utility model can be held tightly when folded; the above-mentioned sunshade cover is a fully enclosed cover that fully wraps the roof and the two sides of the car and the front and rear ends, or a semi-enclosed cover that partially wraps the roof and the two sides of the car; considering that the intensity of sunlight before 8 o'clock in the morning and after 5 o'clock in the afternoon in summer is relatively low, the effect on the temperature rise in the car is very small, and the incident angle of sunlight to the ground at this time is less than 30°, and considering the ventilation and cooling effect and cost saving, the utility model of the above-mentioned semi-enclosed cover has no sunshade cloth between its floor-standing door-shaped cloth frame and its adjacent door-shaped cloth frame, and the maximum angle after unfolding is 30°.

[0005] Further, the above-mentioned floor-standing door-shaped fabric frame is made of a stainless steel pipe profile with a rectangular cross-section shape, and the other door-shaped fabric frames are made of stainless steel pipe profiles with a diameter of 4mm to 8mm or a rectangular cross-section shape. In order to prevent the fulcrum rod from rotating around the bolt axis after the utility model is unfolded or folded, a positioning tongue is provided below the outer end of the fulcrum rod, and the width of the positioning tongue is the same as the width of the guide rail groove.

[0006] In order to further make full use of the technical achievements of the utility model to save resources and to facilitate operation and management, a pair of floor-to-ceiling door-shaped cloth frames of the utility model described above are positioned near the end with a scan code electronic lock. When the utility model is folded, the scan code electronic lock cooperates with the folding hook to lock the utility model. A thin-film photovoltaic cell is provided on the sunshade cloth on the top surface of the sunshade to replenish power for the scan code electronic lock, so that social vehicle owners can scan the code to share the utility model.

[0007] The utility model is used as follows: align the door-shaped opening of the utility model with the front or rear of the car and extend it into the appropriate position in the middle, then scan the code to unlock or release the folding hook, hold all the door-shaped fabric frames except those close to the ground, release the floor-standing door-shaped fabric frame close to the ground and let it fall to the ground, hold the other floor-standing door-shaped fabric frame with both hands and continue to move it to the other end of the car to the appropriate position, then flip it to the ground, adjust the four fulcrum rods to the four wheels and lock them, and then tighten all the quick tightening belts. When folding, loosen the four fulcrum rods, rotate them 90° and then lock them, hold one of the floor-standing door-shaped fabric frames with both hands and fold it up until it is closed with the other floor-standing door-shaped fabric frame, then buckle the folding hook and lock the electronic lock by scanning the code.

[0008] From the above specific technical content, it can be seen that the utility model has the following characteristics: simple structure, quick and convenient folding and unfolding, low cost, large shading area and obvious shading and cooling effect. Since it is equipped with a code scanning electronic lock, it is easy to manage and can be placed in a public parking lot, allowing car owners to scan the code to share. The product utilization rate is greatly improved, and social resources are greatly saved. Car owners do not have to prepare a similar product in the car, saving storage space in the car, and also saving the car owner the trouble of folding and unfolding the sunshade under the scorching sun. It is a project with good market prospects.
