[0001] The utility model relates to the technical field of sunshade and frost prevention, and more specifically to a roof sunshade. Background Art

[0002] With the development of society and the advancement of technology, people's material living standards have undergone fundamental changes. Cars have gradually entered ordinary people's families. Due to the limitations of indoor garages, most cars and passenger vehicles can only be parked in open-air parking spaces. In order to prevent sunlight from directly shining into the car through the windows, people will install sunshades (sunshade cloths) on the car's glass.

[0003] Most of the sunshades currently used are umbrella-shaped structures or folding structures. If they are placed outside the car, they are easily blown away by the wind, and if they are placed inside the car, they cannot block external garbage and impurities. Based on the above problems, we provide a roof sunshade.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0023] The following is combined with Figures 1 to 6 The utility model is described in further detail.

[0024] It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any size is only illustrative and not restrictive. In addition, the same reference symbol is used for the same structure, element or accessory appearing in more than two figures to reflect similar features.

[0025] The utility model embodiment discloses a roof sunshade. Figures 1 to 6A roof sunshade comprises an aluminum tube 1, wherein a rotating tube 3 is rotatably mounted inside the aluminum tube 1 through two bearings 2, and a torsion spring 4 is mounted inside the rotating tube 3 for resetting the rotating tube 3 after rotation; a sunshade cloth 12 is wound around the rotating tube 3, a through hole 5 for stretching the sunshade cloth 12 is opened in the middle of the aluminum tube 1, one end of the sunshade cloth 12 is fixedly connected to a limiting rod 6, and the limiting rod 6 is arranged outside the through hole 5; a one-way mechanism 7 is arranged inside the aluminum tube 1 for limiting the rotating tube 3; an installation mechanism 8 is arranged outside the aluminum tube 1 for installing the aluminum tube 1 on the roof, and the number of the installation mechanisms 8 is two. First, the aluminum tube 1 is installed on the roof of the car through the installation mechanism 8, and then the sunshade cloth 12 is pulled so that the sunshade cloth 12 extends out of the aluminum tube 1, so that the extended sunshade cloth 12 can cover the front windshield of the car, When the sunshade cloth 12 is extended, the rotating tube 3 will rotate. At this time, the torsion spring 4 in the rotating tube 3 will accumulate force and have elastic potential energy. At the same time, due to the provision of a one-way mechanism 7, the one-way mechanism 7 can be used to limit the rotating tube 3 to prevent the rotating tube 3 from rotating and resetting. When the sunshade cloth 12 is rolled up, the rotating tube 3 can be unlocked by the one-way mechanism 7. At this time, the torsion spring 4 will be reset, thereby driving the rotating tube 3 to rotate. The rotating tube 3 rotates to roll up the sunshade cloth 12, and then the sunshade cloth 12 is stored. Through this structural design, the front windshield of the vehicle can be shaded to prevent bird droppings, flying insects or leaves and other garbage from falling on the glass. In winter, frost, snow or ice can be prevented from falling on the glass. Moreover, the structure can automatically roll up the sunshade cloth 12, and there is no need to manually roll up the sunshade cloth 12, which effectively facilitates people's use.

[0026] Specifically, the one-way mechanism 7 includes a one-way bearing 700 assembled in the aluminum tube 1, a driven rod 701 is fixedly assembled in the middle of the one-way bearing 700, a side end of the driven rod 701 is slidably plugged with a snap-fit ​​strip 702, and one end of the snap-fit ​​strip 702 can be plugged into the rotating tube 3, and the other end of the snap-fit ​​strip 702 is fixedly connected with a pull rod 703, and the side end of the pull rod 703 is arranged outside the aluminum tube 1. When the sunshade cloth 12 is pulled out, the pull rod 703 is pushed to rotate. Rod 703 allows the locking strip 702 to be inserted into the rotating tube 3, thereby the driven rod 701 is connected to the rotating tube 3, and the rotation of the rotating tube 3 is limited by the one-way bearing 700 and can only rotate in one direction, thereby overcoming the elastic force of the torsion spring 4. When rolling up the sunshade cloth 12, it is only necessary to separate the locking strip 702 from the rotating tube 3 to release the limitation between the one-way bearing 700 and the rotating tube 3, thereby the torsion spring 4 can be reset to complete the rolling up of the sunshade cloth 12.

[0027] Specifically, a spring 704 is provided in the middle of the pull rod 703 between the aluminum tube 1 and the locking strip 702, for making the locking strip 702 squeeze and contact the rotating tube 3. A handle is fixedly connected to the end of the pull rod 703 away from the aluminum tube 1. By providing the spring 704, the locking strip 702 can be made to fit the rotating tube 3. When releasing the limitation of the one-way bearing 700, the user only needs to pull the locking strip 702 without the need for pushing and pulling, thereby further optimizing the operation of the one-way mechanism 7.

[0028] Specifically, the mounting mechanism 8 includes a connecting sleeve 800 fixedly connected to the side of the aluminum tube 1, the internal thread of the connecting sleeve 800 is equipped with a threaded rod 801, and the bottom end of the threaded rod 801 is fixedly connected to a strong magnet 802. The mounting mechanism 8 is used by installing the threaded rod 801 in the connecting sleeve 800 and then adsorbing the strong magnet 802 on the roof, thereby completing the installation of the entire device on the roof, and the threaded rod 801 can be rotated and adjusted, thereby ensuring the horizontality of the aluminum tube 1 assembled on the roof.

[0029] Specifically, extension cloth 9 is sewn on both sides of the sunshade cloth 12 to increase the coverage area of ​​the sunshade cloth 12, and multiple small magnets 10 are sewn on the sides of the extension cloth 9 to adsorb the extension cloth 9 on the car. By setting the extension cloth 9, full coverage of the glass can be guaranteed.

[0030] Specifically, it also includes a plurality of hooks 11 (attached to the car), and a plurality of through holes are opened on the side of the sunshade cloth 12, which can be mounted on the hooks 11, and the front end of the sunshade cloth 12 can be hung on the hooks 11 through the through holes, thereby preventing the front end of the sunshade cloth 12 from tilting up.

[0031] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0032] The implementation principle of a roof sunshade in an embodiment of the utility model is as follows: first, the aluminum tube 1 is installed on the roof of the car by means of the installation mechanism 8, and then the sunshade cloth 12 is pulled so that the sunshade cloth 12 extends out of the aluminum tube 1, and the sunshade cloth 12 thus extended can cover the front windshield of the car, and when the sunshade cloth 12 is extended, the rotating tube 3 will rotate, and at this time the torsion spring 4 in the rotating tube 3 will accumulate force and have elastic potential energy, and at the same time, since a one-way mechanism 7 is provided, the one-way mechanism 7 can be used to limit the rotating tube 3 to avoid the rotating tube 3 from rotating and resetting, and when the sunshade cloth 12 is rolled up, the rotating tube 3 can be unlocked by the one-way mechanism 7, and at this time the torsion spring 4 will be reset, thereby driving the rotating tube 3 to rotate, and the rotating tube 3 rotates to roll up the sunshade cloth 12, thereby completing the storage of the sunshade cloth 12.

[0033] Regarding the use of the one-way mechanism 7, when pulling out the sunshade cloth 12, by pushing the pull rod 703, the locking strip 702 is inserted into the rotating tube 3, thereby the driven rod 701 is connected to the rotating tube 3, and the rotation of the rotating tube 3 is limited by the one-way bearing 700 and can only rotate in one direction, thereby overcoming the elastic force of the torsion spring 4. When rolling up the sunshade cloth 12, it is only necessary to separate the locking strip 702 from the rotating tube 3 to release the limitation between the one-way bearing 700 and the rotating tube 3, thereby the torsion spring 4 can be reset to complete the rolling up of the sunshade cloth 12.

[0034] The installation mechanism 8 is used by installing the threaded rod 801 in the connecting sleeve 800 and then adsorbing the strong magnet 802 on the roof, thereby completing the installation of the entire device on the roof, and the threaded rod 801 can be rotated and adjusted, thereby ensuring the horizontality of the aluminum tube 1 on the roof.
