Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to an independent photovoltaic sunshade. Background Technology

[0002] In the field of photovoltaic technology, traditional photovoltaic sunshades struggle to balance practicality and energy efficiency due to limitations in their core design. Their power generation components mainly rely on rigid photovoltaic modules. While these modules can meet basic shading and power generation needs, their rigidity prevents the entire sunshade structure from being flexibly retracted or folded. During cloudy or rainy weather, at night, or during special events, they not only continuously occupy fixed space but may also interfere with other activities in the area due to their structural rigidity.

[0003] Meanwhile, the brackets and components of traditional photovoltaic sunshades are mostly fixed installations, which cannot be adjusted in real time according to the dynamic changes in the angle of sunlight (such as changes in the direction of sunlight caused by the alternation of day and night, and differences in the solar altitude angle caused by seasonal changes). This makes it difficult for photovoltaic modules to always maintain the best posture for receiving sunlight, which not only greatly restricts the maximization of power generation efficiency, but also fails to fully release the energy utilization potential of photovoltaic technology.

[0004] Therefore, this application proposes an independent photovoltaic sunshade to solve the problems of traditional sunshades being difficult to store, taking up space, and having difficulty adjusting the angle. Utility Model Content

Their power generation components primarily rely on rigid photovoltaic modules. While these modules can meet basic shading and power generation needs, their rigid material makes the entire sunshade structure inflexible in terms of retraction or folding. During cloudy or rainy weather, at night, or during special events, they not only continuously occupy fixed space but may also interfere with other activities in the area due to structural rigidity.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] In the field of photovoltaic technology, traditional photovoltaic sunshades are limited by their core design, making it difficult to balance practicality and energy efficiency: First, they rely on rigid photovoltaic modules, which can provide basic shading and power generation, but the rigidity of the material makes the structure unable to be flexibly retracted or folded. When not in use, they take up space and may interfere with activities in the area; Second, the brackets and modules are mostly fixed, making it impossible to adjust the angle of sunlight in real time according to changes in day and night and seasons. This makes it difficult for the photovoltaic modules to maintain the best light-receiving posture, which greatly restricts the power generation efficiency and fails to fully unleash the potential of photovoltaic technology.

[0022] Example 1: Please refer to Figure 1 , Figure 2 As shown, an independent photovoltaic sunshade includes a base 1, which is fixed to the ground by expansion bolts or pre-embedded anchors and other connecting parts. The specific method needs to be selected according to the foundation type and project requirements. A mounting box 2 is fixedly installed on the upper end of the base 1. A rotating component 3 is installed inside the mounting box 2. The rotating component 3 is used to fine-tune the angle of the sunshade. As the direction of sunlight changes due to the alternation of day and night or the difference in solar altitude angle caused by the change of seasons, the angle of the sunshade can be flexibly adjusted by the rotating component 3 to improve the power generation efficiency of the flexible photovoltaic panel 59. The rotating component 3 includes a micro motor 31 fixedly installed on the outside of the mounting box 2. The output shaft of the micro motor 31 extends into the inside of the mounting box 2 and is fixedly installed with a connecting sleeve 32. The other end of the connecting sleeve 32 is rotatably connected to the inner side wall of the mounting box 2. A first connecting rod 33 is fixedly sleeved in the middle of the connecting sleeve 32. A drive gear 34 is fixedly installed at the lower end of the first connecting rod 33. A guide gear 35 is rotatably installed at the bottom end of the inner cavity of the mounting box 2. The drive gear 34 meshes with the guide gear 35. A guide groove 36 adapted to the first connecting rod 33 is opened on the upper surface of the mounting box 2. In this embodiment, the micro motor 31 drives the connecting sleeve 32, which is fixedly connected to it, to rotate synchronously. The connecting sleeve 32 not only plays the role of transmitting power, but also provides stable support for the entire transmission structure through rotational connection with the inner side wall of the mounting box 2, avoiding shaking or deviation during power transmission and ensuring the smoothness of the adjustment process. As the connecting sleeve 32 rotates, the first connecting rod 33, which is fixedly sleeved in its middle, will rotate synchronously. The first connecting rod 33 achieves precise angle adjustment through the cooperation of the driving gear 34 and the guide gear 35: on the one hand, the guide gear 35 provides a clear transmission trajectory constraint for the driving gear 34 with its own fixed axis, so that the driving gear 34 can only perform circumferential meshing motion around the gear ring of the guide gear 35, avoiding radial offset when the first connecting rod 33 rotates, and ensuring accurate transmission direction; on the other hand, with the transmission characteristics of gear meshing, the rotational power of the micro motor 31 can be converted into the directional swinging power of the first connecting rod 33. Compared with directly driving the first connecting rod 33 to rotate, gear meshing transmission can effectively reduce power loss and meet the needs of fine adjustment of the sunshade angle under different lighting conditions.

[0023] For further details, please refer to Figure 3 , Figure 4 As shown, a lifting assembly 4 is provided at the upper end of the first connecting rod 33. The lifting assembly 4 is used to flexibly adjust the height of the sunshade. The lifting assembly 4 can adapt to the needs of various activity spaces. For example, when people are standing and moving, the sunshade can be raised to increase headroom, and when placing low objects, the height can be lowered to increase the sunshade coverage density. At the same time, when it is necessary to inspect the photovoltaic modules and transmission structure, the height can be lowered to make the maintenance area closer to the ground, thereby reducing the risk of high-altitude operations and improving the convenience of maintenance.

[0024] The lifting assembly 4 includes a support rod 41 fixedly mounted on the upper end of the first connecting rod 33. An adjusting screw 42 is rotatably mounted inside the support rod 41. A threaded sleeve 43 is threadedly connected to the outer surface of the adjusting screw 42. The outer surface of the threaded sleeve 43 is square and slides in the square inner cavity of the support rod 41. The square design of the threaded sleeve 43 allows it to move up and down along the square inner cavity of the support rod 41 instead of rotating when the adjusting screw 42 rotates, thereby adjusting the height of the sunshade. A first bevel gear 44 is mounted at the lower end of the adjusting screw 42. A second bevel gear 45 is meshed on one side of the first bevel gear 44. A rotating shaft 46 is mounted in the middle of the second bevel gear 45. A rotating handle 47 is mounted on the outer side of the support rod 41 at the end of the rotating shaft 46 away from the second bevel gear 45. In this embodiment, rotating the handle 47 drives the second bevel gear 45 to rotate, and the second bevel gear 45 drives the adjusting screw 42 to rotate through the first bevel gear 44. Because the square inner cavity of the support rod 41 restricts the rotation of the threaded sleeve 43, the threaded sleeve 43 moves up and down along the square inner cavity.

[0025] Example 2: Based on Example 1, please refer to... Figure 5 As shown, a retractable sunshade assembly 5 is provided at the upper end of the threaded sleeve 43. The retractable sunshade assembly 5 includes an umbrella rod 51 fixedly mounted on the upper end of the threaded sleeve 43. An upper trough 52 is fixedly sleeved on the upper end of the umbrella rod 51. A middle trough 53 and a lower trough 54 are slidably sleeved on the outer surface of the umbrella rod 51. Multiple main ribs 55 are rotatably mounted on the upper trough 52, and multiple branch ribs 56 are rotatably mounted on the middle trough 53. The ends of the multiple branch ribs 56 away from the middle trough 53 are rotatably connected to the middle of the corresponding main ribs 55. A return spring 57 is sleeved on the outer surface of the umbrella rod 51 and disposed between the middle trough 53 and the lower trough 54. A sleeve 58 is sleeved on the outer surface of the return spring 57. A set of metal spring clips is also provided on the umbrella rod 51. The clips are divided into mutually cooperating... The umbrella has a male and female buckle. The male buckle is fixedly installed at a designated position on the umbrella pole 51, while the female buckle is pre-sewn or fixed to the corresponding position after the sunshade surface is folded. When the sunshade assembly is fully retracted, the retracted sunshade surface can be firmly fixed to the umbrella pole 51 by the engagement of the male and female buckles, preventing it from loosening during transportation or storage. A flexible photovoltaic panel 59 is set between the two main ribs 55. At the position of the umbrella pole 51 corresponding to the fully unfolded position of the central nest 53, there are multiple metal beads with springs. When the central nest 53 slides up to the unfolded position, the beads pop out under the action of the springs and embed into the pre-set grooves on the inner wall of the central nest 53, directly locking the central nest 53 and preventing it from sliding down, thus structurally locking the unfolded state. When it needs to be retracted, pressing the beads will release the limit, and the central nest 53 can slide down. In this embodiment, when in the retracted state, the middle nest 53 moves closer to the lower nest 54 under the action of the return spring 57. The main rib 55, the branch rib 56, and the flexible photovoltaic panel 59 between the two main ribs 55 all adhere to the umbrella rod 51 and are closed. The female buckle (fixed to the umbrella rod 51) of the metal spring clip on the umbrella rod 51 is fastened to the female buckle to prevent loosening during transportation or storage. When it is necessary to unfold the sunshade, the middle nest 53 is pushed upward to slide along the umbrella rod 51 and compress the return spring 57. The middle nest 53 drives the branch rib 56 to move upward. The branch rib 56 generates an outward pushing force on the middle part of the main rib 55, so that the nest 52 above the main rib 55... The umbrella opens outwards from the fulcrum, simultaneously causing the flexible photovoltaic panel 59 to unfold and form a shading surface. At this time, the spring-loaded metal bead on the umbrella rod 51, corresponding to the fully unfolded position of the central nest 53, pops out and embeds into the groove on the inner wall of the central nest 53 to hold the central nest 53 in place. Combined with the elastic force of the return spring 57, the unfolded state is maintained. When it needs to be retracted, the metal bead is pressed to release the limit, and the central nest 53 is pulled down. The return spring 57 releases its elastic potential energy to assist it in sliding down. The support bone 56 then pulls the main bone 55 down and retracts it inwards. The flexible photovoltaic panel 59 folds with the main bone 55 and is finally re-fastened and fixed by the metal spring clip.

[0026] Furthermore, the installation box 2 is equipped with a storage battery 6, which is connected to multiple flexible photovoltaic panels 59 via connecting wires. During a short break, the flexible photovoltaic panels 59 generate electricity, which is stored in the storage battery 6. Through external sockets, etc., the power can be replenished to electronic products in a timely manner.

[0027] Example 3: This utility model's independent photovoltaic sunshade, while retaining the basic shading function of a conventional sunshade, uses flexible photovoltaic panels 59 to collect sunlight and generate electricity, and is equipped with an energy storage device. This allows users to quickly replenish the power of electronic devices such as mobile phones, laptops, and tablets while taking a short break outdoors, effectively solving the problem of insufficient mobile phone battery when out and about, and addressing the pain point of office workers having difficulty connecting to power banks in coffee shops and other work environments. Furthermore, in addition to traditional styles, this sunshade also supports exclusive customization of company logos, special patterns, and other designs according to needs. Its novel appearance not only meets individual needs but also helps attract foot traffic and enhance brand image. Simultaneously, the photovoltaic charging function can also generate related economic benefits, significantly breaking through the limitations of the single function of existing conventional sunshades.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
