[0003] Some existing charging stations utilize photovoltaic panels to generate solar power. Brackets are installed at the base of the panels, which tilt and support them against the roof of the charging station's canopy.

Furthermore, during rainy weather, rainwater directly impacts the panels and flows along the tilted surface to the upper surface of the canopy, where it then flows to the ground. Due to the confluence of the panels, heavy rainfall can create large, rapid streams, which can land on the same lawn for extended periods, potentially damaging the lawn.

[0035] Example 1

[0036] This embodiment provides a photovoltaic charging station for docking and charging outdoor mobile devices. Figure 1 This is a schematic diagram of the three-dimensional structure of the photovoltaic charging station provided by the embodiment of the utility model. Figure 2 for Figure 1The side view of the photovoltaic charging station is shown in the figure. Figure 1 and Figure 2 The photovoltaic charging station 100 includes a base frame 20 , a shelf 30 and a roof 10 .

[0037] The base frame 20 is fixedly mounted on the support surface, the scaffolding 30 is mounted on the base frame 20, and the roof 10 is mounted on the scaffolding 30. The order of connection from the support surface upward is: base frame 20, scaffolding 30, and roof 10. The roof 10 is supported on the support surface by the scaffolding 30. Outdoor self-propelled equipment can be docked below the roof 10, providing shelter and protection for the equipment docked thereunder.

[0038] In a specific implementation scenario, the outdoor self-moving device is an automatic lawn mower, and the photovoltaic charging station is located within or at the boundary of the automatic lawn mower's working area. When the power level of the automatic lawn mower falls below a preset threshold, it can automatically return to the photovoltaic charging station. In other implementation scenarios, the outdoor self-moving device can also be an inspection robot, used for automatic security inspections in a set area. The outdoor self-moving device can also be a nanny robot, used to provide nanny services in the home or work area. Outdoor robots can also include various other types, each of which is divided according to the type of task it performs, and they are not listed here one by one.

[0039] Specifically, the roof 10 includes a body 11 and a photovoltaic panel 12 disposed on the body 11. The body 11 is disposed on a shelf 30 for supporting the photovoltaic panel 12. Figure 3 As shown, the upper surface of the main body 11 is recessed to form a mounting portion 112, and the photovoltaic panel 112 is arranged on the mounting portion 112. The main body 11 also includes a drain outlet arranged at the bottom of the mounting portion 112, which is used to drain rainwater in the mounting portion 112. The drain outlet is located at the junction of the bottom wall and the side wall of the mounting portion 112. The photovoltaic panel 12 is used to generate electricity using solar energy. It is flat as a whole, and its upper surface is used to receive light. The mounting portion 112 is constructed as a groove that matches the shape of the photovoltaic panel 12. The thickness of the groove is roughly equal to the maximum thickness of the photovoltaic panel 12. The area of ​​the upper surface of the ceiling 10 occupied by the groove is slightly larger than the plate area of ​​the photovoltaic panel 12, so as to facilitate the installation of the photovoltaic panel 12. The electric energy generated by the photovoltaic panel 12 can be stored or directly used to charge outdoor mobile devices.

[0040] The roof 10 has an initial state and an angle adjustment state. In the initial state, as Figure 1 As shown, the photovoltaic panel 12 is embedded in the mounting portion 112, and the upper surface of the photovoltaic panel 12 is substantially flush with the upper surface of the body 11. The body 11 and the photovoltaic panel 12 form a plate-shaped whole, and the roof 10 has a first inclination angle relative to the support surface (see Figure 2In the initial state, there is an assembly gap between the mounting portion 112 and the outer edge of the photovoltaic panel 12. When rainwater hits the upper surface of the roof 10, it will move downward under the action of gravity. Figure 2 As shown in the drawing, the rainwater flows in the left direction, enters the mounting portion 112 through the assembly gap, and is discharged to the outside through the drain port.

[0041] In the angle adjustment state, the photovoltaic panel 12 has multiple second inclination angles relative to the support surface, each second inclination angle being different from the first inclination angle. The photovoltaic panel 12 can be positioned at any of the multiple different second inclination angles. The angle of the photovoltaic panel 12 can be adjusted according to the angle of sunlight, so that the photovoltaic panel 12 is closer to a direction perpendicular to the sunlight, better receiving sunlight and ensuring the photovoltaic panel's power generation efficiency. Regardless of the first inclination angle in the initial state and any second inclination angle in the angle adjustment state, at least a portion of the drain outlet is lower than the entire upper surface of the photovoltaic panel 12, and rainwater that hits the surface of the photovoltaic panel is uniformly discharged through the drain outlet.

[0042] The photovoltaic charging station provided by the present invention has a recessed upper surface of a main body forming a mounting portion for mounting a photovoltaic panel. A drainage outlet is provided at the junction of the bottom wall and side walls of the mounting portion. The roof has an initial state and an angle adjustment state. In the initial state, the photovoltaic panel is embedded in the mounting portion, forming an integral structure with the main body, resulting in a compact and aesthetically pleasing appearance. The roof has a first inclination angle relative to the support surface. In the angle adjustment state, the photovoltaic panel has multiple second inclination angles relative to the support surface. At the first inclination angle and any of the second inclination angles, at least a portion of the drainage outlet is lower than the entire upper surface of the photovoltaic panel. In both the initial state and the angle adjustment state, rainwater on the entire upper surface of the roof is divided into two separate drains. Rainwater that strikes the photovoltaic panel enters the mounting portion and flows out through the drainage outlet provided at the bottom of the mounting portion. Rainwater that strikes the upper surface of the main body flows out from the edge of the main body under the action of gravity. This prevents damage to the lawn caused by the confluence of rainfall into larger streams.

[0043] In the specific embodiments, see Figure 2 The base frame 20 includes a vertical frame 21 connected to the scaffolding 30. The vertical frame 21 extends upward from the support surface, and the scaffolding 30 is connected to the upper part of the vertical frame 21. In this embodiment, the vertical frame 21 is substantially perpendicular to the support surface. The ceiling 10 includes a first side 111 relatively close to the vertical frame 21 and a second side 113 relatively far from the vertical frame 21. The first side 111 and the second side 113 are arranged opposite to each other. In the initial state, the distance between the first side 111 and the support surface is smaller than the distance between the second side 113 and the support surface. Figure 3As shown, the drain outlet includes a first side drain outlet 110, which is arranged at the bottom wall edge of the mounting portion 112 near the first side edge 111. That is, the second side edge 113 is higher than the first side edge 111, and rainwater hitting the upper surface of the main body 11 and the photovoltaic panel 12 will flow to the side close to the stand 21. The first side drain outlet 110 is located at the lower side close to the stand 21. Rainwater hitting the upper surface of the photovoltaic panel 12 enters the mounting portion 112 through the assembly gap between the photovoltaic panel 12 and the main body 11, and is discharged through the drain outlet 110. Figure 2 As can be seen, the roof 10 is tilted slightly upward from the side where it connects to the base frame 20, with this angle being approximately 3-5 degrees. The upper surface of the main body 11 of the roof 10 is square, with a first side 111 being the side of the main body 11 adjacent to the stand 21, and a second side 113 being the side of the main body 11 opposite the first side. The initial tilt helps direct rainwater out through the lower drain opening and the edge of the main body.

[0044] In the angle adjustment state, the photovoltaic panel can be positioned at multiple second tilt angles relative to the support surface to adjust the photovoltaic panel so that sunlight is close to directly hitting the photovoltaic panel, thereby ensuring the photovoltaic panel's power generation efficiency. The following is a specific embodiment to illustrate the implementation method of photovoltaic panel angle adjustment. Figure 3 and Figure 4 As shown, the roof 10 also includes a tilt adjustment mechanism 13, which includes a limiting guide rail 132 and a support link 131. The limiting guide rail 132 is fixed relative to the body 11, and one end of the support link 131 is pivotally connected to the photovoltaic panel 12, and the other end is connected to the limiting guide rail 132. The other end of the support link 131 can slide along the limiting guide rail 132 and be positioned in any one of a plurality of preset positions to adjust the pivot angle of the photovoltaic panel 12 relative to the mounting portion 112. Specifically, the limiting guide rail 132 extends longitudinally and is located below the bottom wall of the mounting portion 112. The limiting guide rail 132 can be fixed to the scaffold 30 or to the bottom wall of the mounting portion 112, without limitation herein. The limiting guide rail 132 is sequentially provided with a plurality of limiting positions (i.e., preset positions) along its length direction. The other end of the support link 131 can slide between the plurality of limiting positions and be positioned at any of the limiting positions. At different limiting positions, the inclination angles of the support link 131 are different, thereby achieving support of the photovoltaic panel 12 at different inclination angles. For example, a screw structure can be used to lock the support link 131 to one of the limiting positions. In this embodiment, the number of the inclination adjustment mechanism 13 is two, which are relatively arranged on both sides of the mounting portion 112. The two limiting guide rails 132 are parallel to each other, and the two support links 131 are respectively connected to support the two sides of the photovoltaic panel 12.

[0045] Specifically, in the initial state and the angle adjustment state, the inclination angle of the body 11 with the support surface remains unchanged. In other words, only the inclination angle of the photovoltaic panel is adjusted, and the position of the body does not change. In this way, when adjusting the angle of the photovoltaic panel, only the photovoltaic panel needs to be operated, which is relatively light and convenient.

[0046] Please combine Figure 3 and Figure 4 In the angle adjustment state, the side of the photovoltaic panel 12 away from the stand 21 remains basically stationary, and the side close to the stand 21 tilts upward to pivot out of the mounting portion 112. It can be understood that if it rains, rainwater hitting the surface of the photovoltaic panel 12 will flow along the lowest point of the photovoltaic panel 12 to the other side of the mounting portion 112 opposite to the first side drain outlet 110. In order to facilitate the discharge of water, in one embodiment, the drain outlet also includes a second side drain outlet 114, which is provided at the bottom wall edge of the mounting portion 112 near the second side 113, and the first side drain outlet 113 and the second side drain outlet 114 are provided at the opposite side edges of the bottom wall of the mounting portion 112. The advantage of this arrangement is that in the angle adjustment state, if it rains, a large amount of rainwater flows out from the side of the photovoltaic panel close to the mounting portion, which can be directly discharged through the second side drain outlet, reducing the risk of it overflowing the mounting portion.

[0047] In the above embodiment, there are multiple first side drain ports 110 and multiple second side drain ports 114 , which are sequentially arranged along the edge of the bottom wall of the mounting portion 112 .

[0048] It is understandable that the photovoltaic panel 12 is exposed to the outdoors for a long time and dust easily falls on the surface. If the surface of the photovoltaic panel is covered with dust and dirt, its photovoltaic power generation efficiency will inevitably be affected. Figure 3 The photovoltaic panel 12 includes photovoltaic cells 121 and a frame 123 disposed around the photovoltaic cells 121. The upper surface of the photovoltaic cells 121 is lower than the frame 123. With this arrangement, rainwater directly hitting the surface of the photovoltaic cells first collects and flows on the surface of the photovoltaic cells, rather than flowing out of the frame. The collected rainwater then flows downward along the surface of the photovoltaic cells under the action of gravity, washing away dust from the surface of the photovoltaic cells and effectively cleaning the photovoltaic cells with rainwater.

[0049] When an outdoor self-propelled device needs to charge or dock, it can automatically return to the photovoltaic charging station and dock under the roof. In this embodiment, the photovoltaic charging station is open in the front and rear directions of the self-propelled device, and the self-propelled device enters and exits the photovoltaic charging station along the same driving direction. To facilitate the self-propelled device's identification of its accurate location at the docking position 230, in a specific embodiment, the chassis 20 also includes a base 23 fixed to the support surface. The base 23 includes a guide belt 231 for enclosing the docking position 230. The guide belt 231 includes opposing and parallel guide edges. The length of the guide edges is generally perpendicular to the direction of entry of the self-propelled device, and the height of the guide edges gradually decreases from the middle to the sides. The two opposing guide edges are similar to speed bumps, with the docking position 230 located between the two guide edges. When the self-propelled device enters the first guide edge, it will need to move up and down the slope. After both the front and rear wheels have passed the first guide edge, the self-propelled device has entered the docking position 230 and can stop driving to remain in the docking position 230. After stopping, even with the effect of inertia, the self-moving device is not likely to rush out of the parking position due to the rising slope of the second guide edge. Therefore, the guide belt can guide the automatic lawn mower entering the parking position and help the self-moving device to stop at the parking position more accurately.

[0050] In the specific embodiments, see Figure 3 The guide belt 231 is provided with positioning holes (not shown), and the guide belt 231 is fixed to the support surface via fasteners 233 that pass through the positioning holes. The base 23 also includes a positioning frame (not shown) fixedly connected to the stand 21. The guide belt 231 covers the positioning frame, maintaining the positioning frame in contact with the support surface. Fasteners 233 securely connect the guide belt and the support surface from both sides of the positioning frame.

[0051] In a specific implementation scenario, the photovoltaic charging station provided in this embodiment is used in conjunction with a mains charging station. The photovoltaic charging station can be installed on the mains charging station and electrically connected to the mains charging station to provide photovoltaic power to the mains charging station. A mains charging station is a power supply station that uses city electricity. The mains charging station is connected to the city's power grid and can charge mobile devices through the city grid. When installed on the mains charging station, the photovoltaic charging station can provide photovoltaic power to the mains charging station, thereby reducing the amount of mains charging power and saving energy.

[0052] Example 2

[0053] See Figure 5 and Figure 6As shown, the present invention also provides a photovoltaic charging station 200. The photovoltaic charging station 200 includes a base frame 20, a trellis 30, and a roof 10'. The difference is that the pivoting structure of the roof 10' is different from that of Example 1. For the sake of simplicity, identical components are numbered the same and are not repeated here.

[0054] See Figure 5 and Figure 6 The ceiling 10' includes a main body 11, a photovoltaic panel 12, and a pivoting positioning mechanism 15 for adjusting the tilt angle of the main body 11. The pivoting positioning mechanism 15 is provided on the shelf 30. The main body 11 is pivotally connected to the shelf 30 via the pivoting positioning mechanism 15. The main body 11 can rotate relative to the shelf 30 to adjust the tilt angle of the main body 11 relative to the support surface. During the rotation of the main body 11 relative to the shelf 30, the photovoltaic panel 12 is driven to switch between multiple second tilt angles and remain embedded in the mounting portion 112. Specifically, the pivoting positioning mechanism 15 has multiple rotation angles. When the rotation angle is zero, it corresponds to the initial state of the ceiling. When the rotation angle is maximum, it corresponds to the maximum tilt angle state of the ceiling (such as Figure 6 The pivot positioning mechanism 15 can employ a damped rotation structure, including a damping member that allows the body 11 to remain at any angle during the rotation process while allowing the body 11 to rotate relative to the frame 30. There are many implementations of the pivot positioning mechanism (such as using a self-locking gas spring), which are not listed here.

[0055] In this embodiment of the photovoltaic charging station, the main body and photovoltaic panels of the roof rotate synchronously to adjust the second tilt angle. During the rotation process, the photovoltaic panels remain embedded in the main body, resulting in a compact and aesthetically pleasing roof appearance. Rainwater on the upper surface of the roof is also ensured to flow out through drainage holes provided at the bottom of the mounting portion and the outer edge of the main body, thereby preventing the risk of large amounts of rainwater accumulating and damaging the lawn.

[0056] Example 3

[0057] The present invention also provides a lawn mowing system comprising an automatic lawn mower and a photovoltaic charging station according to any of the above embodiments. Specifically, the photovoltaic charging station further comprises a mains charging unit connected to the city's electricity grid, enabling the automatic lawn mower to be charged using mains electricity when photovoltaic power generation is insufficient.

[0058] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative work, which should fall within the scope of protection of the present invention.
