Description
Technical Field

[0002] Most of the sunshade umbrellas used for outdoor shading in coffee shops, restaurants, courtyards, parks, etc. are made of rainproof oiled paper cloth for the umbrella leaves and are manually opened and retracted. In this traditional way, the service life of the umbrella depends on the lifespan of the oiled paper cloth. Prolonged exposure to wind and sun will accelerate the aging of the oiled paper cloth. In some places, photovoltaic sunshade umbrellas are used to avoid the service life of the umbrella depending on the lifespan of the oiled paper cloth. However, since photovoltaic sunshade umbrellas are internally provided with electronic components and are relatively heavy, they are usually fixed to the ground. In case of severe weather such as strong winds and heavy rains, the photovoltaic sunshade umbrellas cannot be retracted, and the umbrella leaves or internal components may be damaged, and the umbrella leaves may fall, posing a risk of injuring pedestrians or buildings.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0035] Embodiment:
[0036] As Figures 1 to 6 shown, an automatic folding lightweight photovoltaic sunshade umbrella includes: a support assembly 1 and a sunshade assembly 2. The support assembly 1 is rotatably connected to the sunshade assembly 2, and the sunshade assembly 2 is disposed at the top of the support assembly 1.
[0037] As Figure 3 and Figure 4 shown, the support assembly 1 includes: a support rod 12 and a motor 121. The motor 121 is disposed inside the support rod 12, and a rotating shaft 122 is provided at the top of the motor 121. The motor 121 drives the rotating shaft 122 to rotate; a base 11 is provided at the bottom of the support rod 12, and a telescopic rod 111 is disposed inside the base 11. The top of the telescopic rod 111 is connected to the bottom of the support rod 12, and the telescopic rod 111 drives the support rod 12 to rise or fall into the base 11; a plurality of sliding grooves 123 are formed at the top of the support rod 12, and the plurality of sliding grooves 123 are arranged equidistantly along the axial direction of the support rod 12; the arc lengths of the plurality of sliding grooves 123 are distributed in an increasing arithmetic progression along the bottom direction of the support rod 12, and the common difference of the arc lengths of the plurality of sliding grooves 123 is the arc length of the sliding groove 123 provided at the top of the support rod 12. That is to say, assuming the arc length of the topmost sliding groove 123 is l, the arc lengths of the following sliding grooves 123 are 2l, 3l, 4l, etc., and so on.
[0038] As Figure 5 and Figure 6As shown in the figure, the sunshade assembly 2 includes: a plurality of sunshade panels 21 and a plurality of photovoltaic modules 22. The plurality of photovoltaic modules 22 are respectively arranged on the plurality of sunshade panels 21. The photovoltaic modules 22 convert solar energy into electrical energy. A lighting device or a charging device can be arranged near the parasol, and the electrical energy converted by the photovoltaic modules 22 powers them; the number of the plurality of sunshade panels 21 is equal to the number of the plurality of chutes 123; one end of each of the plurality of sunshade panels 21 penetrates through the plurality of chutes 123 respectively and then extends into the interior of the support rod 12. The sunshade panels 21 slide in the chutes 123 respectively, and the topmost sunshade panel 21 does not slide; an inner ring 23 is arranged at one end of the sunshade panel 21. The inner ring 23 is sleeved on the outer side of the rotating shaft 122, and the inner ring does not contact the rotating shaft 122; an outer ring 24 is further arranged at one end of the sunshade panel 21. The outer ring 24 is arranged on the outer side of the inner ring 23, and the outer ring 24 is sleeved on the outer side of the support rod 12; the sunshade panel 21 is of a sector structure. The plurality of sunshade panels 21 overlap or the plurality of sunshade panels 21 form a circular structure. The motor 121 drives the rotating shaft 122 and then drives the sunshade panel 21 to rotate. The sunshade panels 21 rotate from one end of the chute 123 to the other end of the chute 123 respectively to form a circular structure. The motor 121 rotates in the opposite direction to drive the sunshade panel 21 to rotate to one end of the chute 123, and the sunshade panels 21 overlap, which is convenient for subsequent folding and closing.
[0039] A first connecting plate 211 is arranged on one side of the sunshade panel 21, and a second connecting plate 212 is arranged on the other side of the sunshade panel 21. The photovoltaic module 22 is arranged on the first connecting plate 211; a waterproof layer 25 is arranged on the upper surface of the photovoltaic module 22. The waterproof layer 25 protects the photovoltaic module 22 from being damaged by rain in rainy weather; the first connecting plate 211 is matched with the second connecting plate 212. Two adjacent sunshade panels 21 are abutted against each other through the first connecting plate 211 and the second connecting plate 212. The first connecting plate 211 is arranged on the upper surface of the second connecting plate 212. By abutting the first connecting plate 211 against the upper surface of the second connecting plate 212, the gap between the sunshade panels 21 is reduced, and thus the sunshade effect is improved.
[0040] One end of a plurality of sliding grooves 123 is located on the same vertical line. Elastic pieces 231 are arranged on the inner wall of the inner ring 23. The elastic pieces 231 and the other ends of the sliding grooves 123 are located on the same vertical plane. When they coincide, the elastic pieces 231 on each sunshade 21 are in different positions. When the sunshade 21 is circular, the elastic pieces 231 on each sunshade 21 are all at the other ends of the corresponding sliding grooves 123. Springs 232 are also arranged on the inner wall of the inner ring 23. The other ends of the springs 232 are connected to the elastic pieces 231. The topmost sunshade 21 may not be provided with the elastic pieces 231 and the springs 232. A plurality of push blocks 1221 are arranged on the side wall of the rotating shaft 122. The plurality of push blocks 1221 are located on the same vertical line. The number of the plurality of push blocks 1221 is equal to that of the plurality of elastic pieces 231. The push blocks 1221 are in contact with the elastic pieces 231. When the motor 121 drives the rotating shaft 122 to rotate, the push blocks 1221 on the rotating shaft 122 gradually collide with the elastic pieces 231 on the inner ring 23, thereby driving the sunshade 21 to rotate. When the sunshade 21 rotates to the other end of the sliding groove 123, the sunshade 21 stops rotating. The rotating shaft 122 continues to rotate. At this time, the push blocks 1221 bend the elastic pieces 231, the springs 232 are compressed, the push blocks 1221 turn past the elastic pieces 231, and the springs 232 are released to make the elastic pieces 231 return to their original positions.
[0041] In summary, when the sunshades 21 are in the retracted state and all the sunshades 21 are located at one end of the sliding grooves 123, the motor 121 is started. When the motor 121 drives the rotating shaft 122 to rotate, the push blocks 1221 on the rotating shaft 122 gradually come into contact with the elastic pieces 231 on the inner ring 23, thereby driving the sunshades 21 to rotate. When the sunshades 21 rotate to the other end of the sliding grooves 123, the sunshades 21 stop rotating. The rotating shaft 122 continues to rotate. At this time, the push blocks 1221 bend the elastic pieces 231, the springs 232 are compressed, the push blocks 1221 turn past the elastic pieces 231, and the springs 232 are released to make the elastic pieces 231 return to their original positions. When the sunshades 21 need to be retracted, the motor 121 rotates in the opposite direction to drive the sunshades 21 to rotate to one end of the sliding grooves 123. During this process, the push blocks 1221 on the rotating shaft 122 gradually come into contact with the elastic pieces 231 on the inner ring 23, thereby driving the sunshades 21 to rotate. After the sunshades 21 coincide, the telescopic rod 111 is started, and the telescopic rod 111 lowers the support rod 12 and the sunshades 21. The telescopic rod 111 descends into the base 11 to complete the retraction and transfer of the sunshade.
