[0002] For many people, UV protection is very important in daily life. Although it can promote the synthesis of vitamin D in the human body and prevent rickets, long-term high-intensity UV radiation will cause the skin to produce a large number of free radicals, leading to peroxidation of the cell membrane, causing melanocytes to produce more melanin, resulting in wrinkles, aging, sagging and dark spots on the skin. More seriously, it may also cause skin cancer. Long-term exposure to irritate the eyes can also cause macular degeneration of the retina. Therefore, when doing outdoor activities, more people are particularly concerned about UV protection.

[0003] Nowadays, when people are doing outdoor activities, they usually wear sun-protective clothing and apply sunscreen for effective protection. However, if they are exercising, too much sun-protective clothing will have a certain impact on the exercise, and the sweat produced during exercise will also affect the protective effect of the sunscreen.

[0031] The present application provides a bottom-mounted intelligent companion flying robot, comprising a top plate 10, a shielding body 20 and a spiral power assembly 30 arranged from top to bottom. Figure 1 and Figure 2As shown, a top connector 11 is provided on the top plate 10, and the top of the shielding body 20 is connected through the top connector 11. A support connector 23 is provided below the shielding body 20, and a vent 21 is provided in the middle of the shielding body 20. The spiral power assembly 30 is rotatably connected to the support connector 23 and is located below the vent 21. The spiral power assembly 30 is circumferentially provided with a spiral wing 31. The top plate 10 is located above the vent 21. When in a shielding state, an air duct connected to the vent 21 is ensured to be formed between the shielding body 20 and the top plate 10 to ensure smooth airflow during the rotation of the spiral wing 31. The above-mentioned spiral power assembly 30 is rotatably connected to the support connector 23, so that the shielding body 20 can rotate relative to the spiral power assembly 30 during use, thereby realizing the convenient change of its shielding angle following the sun's irradiation, so that the shielding body 20 is always facing the direction of the sun, so as to provide the user with the largest shielding area and achieve an efficient protection effect.

[0032] Specifically, a support member 22 is provided at the vent 21, and both ends of the support member 22 are respectively mounted on the inner edge of the shielding body 20. Figure 5 As shown, the support member 22 can be set as a cross structure, and the four ends are respectively set at different positions of the inner edge of the shielding body 20. The top of the support member 22 is connected to the top connector 11, and the bottom is connected to the spiral power assembly 30. Specifically, the top connector 11 and the spiral power assembly 30 are both arranged at the intersection of the cross structure of the support member 22. Preferably, the top connector 11 and the support member 22 are detachably connected, and can be selected in the form of threaded connection or clamping. In addition, the structure of the above-mentioned support member 22 can also be set to a straight structure, an H-shaped structure, etc., which is not specifically limited in this application.

[0033] In one embodiment of the present application, the projection of the top plate 10 on the shielding body 20 completely covers the vent 21. The projection here refers to the projection of the top plate 10 on the shielding body 20 when looking down from the top of the top plate 10, that is, Figure 1 The state when the top plate 10 is projected onto the shielding body 20 from top to bottom. Figure 4 As shown, the projection of the top plate 10 completely covers the vent 21. At this time, the top connector 11 can be preferably set as a telescopic rod, so that the top plate 10 is connected to the shielding body 20 by lifting. When in the shielding state, the top plate 10 rises relative to the shielding body 20, and an air duct connected to the vent 21 is formed between the top plate 10 and the shielding body 20 to ensure smooth air flow during the rotation of the spiral wing 31, making the flight more stable and safe; when in the storage state, the top plate 10 descends relative to the shielding body 20, so that at least the outer periphery of the top plate 10 is against the shielding body 20. At this time, the air duct between the top plate 10 and the shielding body 20 disappears, and the two are in the most fitting state, so that the height of the bottom-mounted intelligent companion flying robot in the storage state is minimized, thereby reducing the size of the space occupied by the robot after storage.

[0034] In another embodiment of the present application, the projection of the top plate 10 on the shielding body 20 only covers a portion of the vent 21, such as Figure 6 As shown, it is one of the partial covering situations. At this time, no matter the top plate 10 is against the shielding body 20 or there is a certain distance between the top plate 10 and the shielding body 20, there is always a ventilation area between the two, that is, there is always an air duct for the airflow formed by the spiral wing 31 to pass through. Therefore, at this time, the top plate 10 can be directly against the shielding body 20 and set above the shielding body 20. Of course, in order to make the airflow more smooth and stable, it is preferred to set the top plate 10 in a form that can be raised and lowered relative to the shielding body 20. On the one hand, it is convenient to improve the stability of the flight, and on the other hand, it is convenient to store and reduce the storage space.

[0035] As a preferred solution, the projection of the top plate 10 on the shielding body 20 completely covers the vent 21, so as to further increase the shielding area and ensure the best shielding effect. In order to prevent the light from passing through the space between the top plate 10 and the vent 21 and shining on the user when the sun shines obliquely, the projection of the top plate 10 just covers the vent 21 - preferably when the two are of the same shape and size, the outer circumference of the top plate 10 is increased by a certain size, so that the top plate 10 is larger than the vent 21. Figure 4 and Figure 5 As shown, when both the top plate 10 and the vent 21 are circular, the radius R1 of the top plate 10 is larger than the radius R2 of the vent 21. Specifically, R1=R2+(10%-20%)R2, so that when the top plate 10 cooperates with the shielding body 20, the sunlight can be better shielded without being affected by the vent 21. Specifically, the radius of the top plate 10 and the radius of the vent 21 can be specifically set according to the height of the top plate 10 relative to the shielding body 20, and are not limited to the above dimensions.

[0036] In a specific embodiment, the top plate 10 and the shielding body 20 are both configured as structures with a circular outer periphery, and the vent 21 is also configured as a circular structure, such as 4 and Figure 5 As shown, in actual configuration, the outer peripheral shapes of the top plate 10 and the shielding body 20 are not limited to circular, but may also be elliptical, rectangular, etc. Figure 6 As shown, the outer periphery of the top plate 10 is a rectangular structure, and the vent 21 is also a rectangular vent. At this time, the outer periphery of the shielding body 20 can be a rectangle, or can be set to other shapes, without specific limitation. As a preferred solution, Figure 1As shown, the top plate 1 and the shielding body 20 are configured as a convex structure, and specifically, the convex height gradually increases from the outer edge of the top plate 1 and the shielding body 20 to the center of the top plate 1 and the shielding body 20. When in use, the convex part faces the ascending direction. This configuration can reduce the air resistance of the bottom-mounted intelligent companion flying robot when ascending, thereby making the flight more flexible and the following more sensitive.

[0037] In a preferred embodiment of the present application, the bottom-mounted intelligent companion flying robot also includes a mobile windshield 24, which is used to control the opening and closing of the variable air outlet. The mobile windshield 24 and the variable air outlet are set to expand the ventilation area, so that after the spiral power assembly 30 rotates relative to the shielding body 20, there is also an air duct for air flow just above the surface of the spiral wing 31 - that is, in a direction parallel to the axial direction of the spiral wing 31 - so that the air flow is smoother and the flight is more stable. Figure 3 As shown, after the spiral wing 31 rotates relative to the shielding body 20, the ventilation area corresponding to the spiral wing 31 rotating in the direction away from the shielding body 20 is reduced to a certain extent. Therefore, in order to avoid the influence of the change in ventilation area on its rotation and ensure that the flight is always in a stable and safe state, at this time, the movable windshield 24 on this side is moved away to expose the variable air outlet, so that the ventilation area corresponding to the spiral wing 31 rotating in the direction away from the shielding body 20 is increased, further improving the stability of the flight. When not deflected or not in use, the movable windshield 24 shields the variable air outlet.

[0038] Specifically, the variable air outlet is arranged on the shielding body 20 and is located at the position on the shielding body 20 corresponding to the surface of the spiral wing 31 along the axial direction after the spiral wing 31 is deflected, and the size of its ventilation area is at least the size corresponding to the surface of the spiral wing 31. The variable air outlet is especially arranged at the position on the shielding body 20 corresponding to the spiral wing 31 with a larger deflection angle. Figure 8 As shown, when four spiral wings 31 are provided, the shielding body 20 rotates, and two of the spiral wings 31 completely correspond to the rotation direction. At this time, the variable air outlet and the movable windshield 24 are provided at the positions of the left and right spiral wings 31 corresponding to the shielding body 20, as shown in FIG. Figure 5 As shown, the other two can be ignored because their corresponding ventilation areas change very little during rotation.

[0039] Specific plans such as Figure 7As shown, one spiral wing 31 is respectively arranged at the positions corresponding to the two ends of the slide slot 331 on the spiral power assembly 30, and two variable air ports are arranged, and are respectively located at the positions corresponding to the spiral wings 31 after deflection corresponding to the two ends of the slide slot 331. At this time, the two spiral wings 31 located at the two ends of the slide slot 331 have the largest deflection angle when deflecting with the spiral power assembly 30, so the position corresponding to the surface of the spiral wings 31 on the shielding body 20 has undergone a significant change. At this time, the variable air port and the movable windshield 24 are arranged on the shielding body 20, specifically at the positions corresponding to the surfaces of the spiral wings 31 after deflection corresponding to the two ends of the slide slot 331.

[0040] In addition, when multiple movable windshields 24 are provided, only one of the movable windshields 24 can be opened according to the use requirements, or more movable windshields corresponding to the rotating spiral wings 31 can be opened. Of course, it is also feasible to open all of them at the same time. In addition, multiple movable windshields 24 can be provided according to the rotation and number of the spiral wings 31, or a whole one can be provided, and it can be directly opened as a whole when needed.

[0041] In this embodiment, preferably, the movable windshield 24 is slidably arranged on the shielding body 20, or the movable windshield 24 is foldably and telescopically arranged on the shielding body 20, or the movable windshield 24 is flipped and arranged on the shielding body 20. Figure 5 For example, the movable windshield 24 can rotate around the inner circle of the shielding body 20, so that it can slide from the top of the variable air outlet to the adjacent position when necessary, thereby increasing the ventilation area. It can also be set as a folding and telescopic structure, for example, the movable windshield 24 can be folded and telescopic in a wave shape to meet the needs of use. The movable windshield 24 can also be rotatably installed on the shielding body 20, and when necessary, it can be flipped relative to the shielding body 20 to expose the variable air outlet. Of course, the movement method of the movable windshield 24 is not limited to the above structure, and it can be realized that the variable air outlet is exposed when necessary.

[0042] In one embodiment, Figure 5 and Figure 7As shown, an arc-shaped slide groove 331 is arranged in the groove of the spiral connector 33 of the spiral power assembly 30, a protrusion located in the groove is arranged at one end of the support connector 23 away from the shielding body 20, and a slider (not shown) slidably connected to the slide groove 331 is arranged on the protrusion, and the shielding body 20 rotates along the direction of the slide groove 331 relative to the spiral power assembly 30. After the rotation, the shielding body 20 tilts to shield the obliquely irradiated sunlight. Preferably, the protrusion is a spherical structure, the groove is arranged as an arc-shaped groove covering the protrusion, and the size of the groove opening is smaller than the diameter of the protrusion, that is, the protrusion is covered by the groove, the protrusion can rotate in the groove, but cannot leave the spiral connector 33 from the groove opening, so that the shielding body 20 and the spiral power assembly 30 are rotationally fixedly connected. At this time, in order to facilitate disassembly, the spiral connector 33 can be set to two parts that can be opened. After opening, the protrusion on the support connector 23 can be installed or removed. After closing, the protrusion cooperates with the slide groove 331 and fixes the support connector 23 and the spiral connector 33 to each other, so that the two are firmly installed during rotation.

[0043] In addition, as a preferred embodiment, the bottom-mounted intelligent companion flying robot also includes a self-locking device for limiting the rotation between the spiral power assembly 30 and the supporting connector 23. The state of the self-locking device can be changed by the control device in the spiral power assembly 30. When the shielding position is adjusted, the self-locking device locks and limits the movement between the shielding body 20 and the spiral power assembly 30, so that the two are in a relatively fixed state, so that the shielding effect is stable, and the wind force, the airflow when the spiral wing 31 rotates, and other factors affect the position of the shielding body 20, causing it to rotate, thereby better ensuring the shielding effect. When the control device detects that the position of the shielding body 20 needs to be adjusted, the self-locking device is unlocked, and the shielding body 20 rotates relative to the spiral power assembly 30 to reach the position of maximum shielding effect, and is locked.

[0044] In one embodiment of the present application, the shielding body 20 includes a support frame and a shielding cloth. The support frames are evenly distributed along the circumference of the shielding body 20, and one end of each support frame is arranged at the inner edge of the shielding body 20, and the other end is arranged at the outer edge of the shielding body 20. In this case, the support frame can be preferably arranged as a telescopic frame. When in use, the support frame extends and stretches out the shielding cloth thereon; when stored, the support frame contracts toward the inner edge of the shielding body 20, and drives the shielding cloth to be folded together, thereby making the overall bottom-mounted intelligent companion flying robot smaller in size, occupies less space, and is more convenient to store. Of course, the setting method and specific structure of the support frame are not limited to the above situation, and can also be set as follows Figure 8The circular skeleton shown can be set as an open skeleton at this time for the convenience of storage, and the shielding cloth can be separated at the opening so that the two sides of the opening can be detachably connected, such as snap connection, Velcro connection or zipper connection, and the circular skeleton itself is also set as a telescopic structure. After opening the connection at the opening, the shielding body 20 can be stored as the circular skeleton shrinks.

[0045] The shielding cloth is preferably a shielding mesh cloth, so as to achieve the shielding effect while reducing the overall weight of the bottom-mounted intelligent companion flying robot. The density of the shielding mesh cloth here needs to meet the shielding requirements, such as being able to block enough sunlight, etc. In a preferred embodiment, the shielding cloth is set to be detachably connected to the support frame to facilitate disassembly, which is convenient for cleaning and maintenance, and also easy to replace. It can be replaced with other types or required shielding cloths, such as replacing the shielding mesh cloth with a rainproof shielding component.

[0046] The bottom-mounted intelligent companion flying robot of this embodiment further includes a power device 32, on which the spiral wing 31 is mounted through a deflection member, and the power device 32 is fixedly mounted on the spiral power assembly 30. Figure 7 As shown, after the deflection member is provided, the rotation axis of the spiral wing 31 can always be kept vertical, so that the airflow and the spiral wing 30 interact more stably, further ensuring smoother lifting and suspension.

[0047] The spiral wings 31 are arranged around the spiral power assembly 30 and are evenly distributed around the spiral power assembly 30. Specifically, the spiral wings 31 can be arranged in multiple groups. In the present application, at least three groups of spiral wings 31 are preferably arranged. Figure 7 As shown, a solution in a specific embodiment of the present application is shown, in which four sets of spiral wings 31 are provided, and the angle between two adjacent spiral wings 31 is 90°. It is also possible to preferably provide six or eight sets of spiral wings 31, so that the bottom-mounted intelligent companion flying robot can achieve flexible steering and improve the sensitivity of the bottom-mounted intelligent companion flying robot in intelligent following and providing shielding services.

[0048] The bottom-mounted intelligent companion flight robot provided in the embodiment of the present application is provided with a top plate 10, a shielding body 20 and a spiral power assembly 30 in sequence from top to bottom. Through the cooperation of the top plate 10 and the shielding body 20, a sufficient shielding area is provided for the user, and its protection method is simpler and more convenient. The setting of the vents 21 and the air duct between the top plate 10 and the shielding body 20 ensures that the airflow generated when the spiral wings 31 on the spiral power assembly 30 rotate can flow smoothly, making the flight process smoother and safer. Therefore, the above-mentioned bottom-mounted intelligent companion flight robot simultaneously achieves the effect of simple use and convenient protection, as well as providing efficient shielding.

[0049] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
