[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the basic concepts disclosed and indicated in the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

[0032] Figure 1 This is a structural schematic diagram of a photovoltaic floor tile provided in an embodiment of the present invention. Figure 2 For along Figure 1 A schematic diagram of the cross-sectional structure of section A-A', see reference. Figure 1 and Figure 2The photovoltaic floor tile 100 includes a frame 10, a photovoltaic module 20, an energy storage device 30, a control device 40, and a load 50. The frame 10 includes a receiving slot 11 and a load receiving slot 12 surrounding the receiving slot 11. The receiving slot 11 is used to place the photovoltaic module 20, and the load receiving slot 12 is used to place the load 50. The photovoltaic module 20 includes a first region 21 and a second region 22 surrounding the first region 21. In the direction Z perpendicular to the plane of the photovoltaic module 20, the second region 22 overlaps with the receiving slot 11, while the first region 21 does not overlap with the receiving slot 11. The photovoltaic module 20 includes a light-incident surface 23 and a back-light surface 24. The energy storage device 30 and the control device 40 are located on the side of the back-light surface 24 away from the light-incident surface 23. In the direction Z perpendicular to the plane of the photovoltaic module 20, the energy storage device 30 and the control device 40 overlap with the first region 21. The photovoltaic module 20 is electrically connected to the energy storage device 30, the energy storage device 30 is electrically connected to the control device 40, and the control device 40 is electrically connected to the load 50.

[0033] The frame 10 is made of materials such as magnesium-aluminum alloy or other metal profiles or polymer composite materials. The load 50 includes light strips or sensors, which can be configured according to actual needs and are not specifically limited here. The energy storage device 30 includes a (lithium-ion) battery, a battery management system, and a safety system. The battery is used to store the electrical energy generated by the photovoltaic module 20. The battery management system can monitor the battery's operating parameters in real time, such as battery voltage, current, operating temperature, and charge / discharge status. When the operating parameters exceed normal thresholds, it provides the safety system with information for overcharge protection, over-discharge protection, over-temperature protection, short-circuit protection, or battery equalization, so that the safety system can perform corresponding protective operations on the battery, thereby improving the battery's operating safety and extending the service life and operational reliability of the energy storage device 30.

[0034] Specifically, by providing a receiving slot 11 on the frame 10, the photovoltaic module 20 is placed into the receiving slot 11, ensuring the reliability of the photovoltaic module 20's fixation and preventing stress damage to the photovoltaic module 20 during the installation of the photovoltaic floor tile 100, thus improving the safety of the photovoltaic module 20. The load receiving slot 12 is arranged around the receiving slot 11 to avoid placing the load receiving slot 12 on the light-incident surface 23 of the photovoltaic module 20, which would affect the light-incident rate of the photovoltaic module 20, thereby improving the photoelectric conversion efficiency of the photovoltaic module 20 and increasing the utilization rate of solar energy. Furthermore, since the first region 21 does not overlap with the receiving slot 11, the heat generated by the photovoltaic module 20 can be released through the backlight surface 23 located in the first region 21, improving the heat dissipation effect of the photovoltaic module 20. The energy storage device 30 and the control device 40 are positioned on the side of the backlight surface 24 away from the light-receiving surface 23, and in the direction Z perpendicular to the plane where the photovoltaic module 20 is located. The energy storage device 30 and the control device 40 overlap with the first region 21 to ensure the light-receiving rate of the photovoltaic module 20, while making the structure of the photovoltaic floor tile 100 compact, improving the integration of the photovoltaic floor tile 100, and improving the heat dissipation effect of the energy storage device 30 and the control device 40. The energy storage device 30 is electrically connected to both the photovoltaic module 20 and the control device 40, so that the electrical energy generated by the photovoltaic module 20 can be transmitted and stored in the energy storage device 30. The control device 40 can control the power supply status of the energy storage device 30 to the load 50 based on parameters such as the power level of the energy storage device 30. In this way, the control device 40, energy storage device 30, photovoltaic module 20 and load 50 can be integrated into the same photovoltaic floor tile 100, improving the integration of the photovoltaic floor tile 100. When the photovoltaic floor tile 100 malfunctions, a new photovoltaic floor tile 100 can be replaced, reducing the maintenance cost of the photovoltaic floor tile 100 and improving maintenance efficiency.

[0035] It should be noted that the control device 40 may include a power management unit and an energy distribution unit. The power management unit is responsible for monitoring the power output of the photovoltaic modules, including voltage and current regulation. The power management unit also incorporates a maximum power point tracking algorithm to ensure that the photovoltaic modules always operate in their optimal state, maintaining maximum power generation efficiency. The energy distribution unit allocates power according to real-time energy demand and priority. Whether supplying power to the load 50 or storing energy, the control device 40 ensures efficient and rational processes. The photovoltaic floor tile 100 can also reserve a port for grid power supply, allowing the power generated by the photovoltaic floor tile 100 to be transmitted to the grid. In the event of a grid power outage, the control device 40 can also control the energy storage device 30 to automatically switch to energy storage power supply mode, ensuring continuous power supply.

[0036] The technical solution provided by this utility model improves the integration of photovoltaic (PV) floor tiles and reduces their maintenance costs by integrating PV modules, energy storage devices, control devices, and loads into the same frame. Furthermore, by setting the second zone of the PV module to overlap with the receiving slot of the frame, while the first zone does not overlap, the energy storage device and control device are located on the side of the PV module's back surface facing away from the light-receiving surface. In a direction perpendicular to the plane of the PV module, the energy storage device and control device overlap with the first zone, ensuring that the energy storage device, control device, and PV module overlapping with the first zone are not obstructed by the frame. This allows the heat generated during operation of the PV module, energy storage device, and control device to be released promptly, improving the heat dissipation efficiency of the PV floor tiles, reducing the impact of operating temperature on the PV floor tiles, and extending their service life.

[0037] Optional, Figure 3 A cross-sectional structural diagram of a frame provided for an embodiment of this utility model, with reference to... Figure 1 and Figure 3 The frame 10 includes a base plate 13; in the direction Z perpendicular to the plane where the photovoltaic module 20 is located, the surface of the area where the base plate 13 overlaps with the second area 22 is provided with at least one first protrusion 131 and at least one groove 132 surrounding the first protrusion 131; the photovoltaic module 20 is placed on the side of the first protrusion 131 away from the base plate 13.

[0038] The number of the first boss 131 and the groove 132 can be set according to actual needs. Figure 3 The image shows that the frame 10 includes two first protrusions 131, namely first protrusion 1311 and first protrusion 1312, and a groove 1321 surrounding the first protrusion 1311 and a groove 1322 surrounding the first protrusion 1312. Figure 4 A cross-sectional view of another frame structure provided for an embodiment of this utility model, as shown below. Figure 4 As shown, the frame 10 includes a first boss 131 and a groove 132. It should be noted that when multiple first bosses 131 and multiple grooves 132 are provided, the width of the first bosses 131 and the grooves 132 is relatively small.

[0039] Specifically, by providing a first protrusion 131 and a groove 132, the heat generated during the operation of the photovoltaic module 20 can be released into the groove 132, improving the heat release efficiency of the photovoltaic module 20 and preventing the photovoltaic module 20 from operating at high temperatures for extended periods, which could lead to malfunctions. Furthermore, when the width of the first protrusion 131 is small enough to facilitate the installation of a transverse through-hole, a through-hole parallel to the plane of the photovoltaic module 20 can be provided in the first protrusion 131. Electrical connection wires can then pass through this through-hole and the groove 132 to connect to the load 50. This avoids the electrical connection passing through the area between the first protrusion 131 and the photovoltaic module 20, which could cause the photovoltaic module 20 to be unstable or, under prolonged heavy pressure, potentially lead to the breakage of the electrical connection wires between the first protrusion 131 and the photovoltaic module 20. Thus, by providing at least one first protrusion 131 and a groove 132 surrounding the first protrusion 131, the stability of the photovoltaic module 20 and its heat dissipation efficiency are ensured.

[0040] Optional, see reference Figure 2 and Figure 3 The frame 10 also includes a top plate 14; the top plate 14 includes a first part 141 constituting a load receiving groove 12 and a second part 142 constituting a receiving slot 11; in the thickness direction perpendicular to the photovoltaic module 20, the second part 142 overlaps with a portion of the second region 22.

[0041] Specifically, by setting the second part 142 to overlap with a portion of the second region 22, the second part 142 engages the light-receiving surface 24 of the photovoltaic module 20, preventing the photovoltaic module 20 from sliding along the Z direction during transportation and improving the installation stability of the photovoltaic module 20 in the Z direction. Furthermore, the second part 142 does not overlap with the entire second region 22, allowing the photovoltaic module 20 to have a larger area for receiving sunlight, thus improving the photoelectric conversion efficiency and light energy utilization rate of the photovoltaic module 20.

[0042] Optional, see reference Figure 3 or Figure 4 The bottom plate 13 includes a second boss 133 on the side near the top plate 14; in the extension direction of the photovoltaic module 20, the second boss 133 is located between the receiving slot 11 and the load receiving slot 12.

[0043] Specifically, by setting the second protrusion 133, after the photovoltaic module 20 is placed into the receiving slot 11, the photovoltaic module 20 can be blocked by the second protrusion 133 in the extending direction of the photovoltaic module 20, thereby restricting the photovoltaic module 20 from sliding in the horizontal direction and affecting the devices inside the photovoltaic module 20, thus ensuring the placement stability and working reliability of the photovoltaic module 20.

[0044] Optional, see reference Figure 3 or Figure 4The top plate 14 includes a third boss 143 on the side near the bottom plate 13; in the extension direction of the photovoltaic module 20, the third boss 143 is located between the receiving slot 11 and the load receiving slot 12.

[0045] Specifically, in addition to the second protrusion 133 on the base plate 13, a third protrusion 143 can be provided on the side of the top plate 14 near the base plate 13. After the photovoltaic module 20 is placed into the receiving slot 11, the photovoltaic module 20 can be blocked by the second protrusion 133 and the third protrusion 143 in the extension direction of the photovoltaic module 20, so as to limit the horizontal sliding of the photovoltaic module 20 and prevent it from affecting the devices inside the photovoltaic module 20, thereby further improving the placement stability and working reliability of the photovoltaic module 20.

[0046] Optional, continue to refer to Figure 2 The load 50 includes multiple light strips; the light-emitting surface of the light strips faces the photovoltaic module 20.

[0047] The light strip includes multiple light-emitting diodes arranged horizontally and vertically. The number of light-emitting elements such as light-emitting diodes in the light strip can be set according to the size of the load receiving slot 12, etc., and no specific limitation is made here.

[0048] Specifically, by aligning the light-emitting surface of the light strip towards the photovoltaic module 20, the light beam emitted from the light strip can be emitted through the area between the second protrusion 133 and the third protrusion 143 to the side surface of the photovoltaic module 20, and then emitted from the light-incident surface 23 of the photovoltaic module 20, thus improving the aesthetics of the photovoltaic floor tile 100. It is understood that, due to the relatively large size of the photovoltaic module 20, the light emitted from the light strip, after passing through the photovoltaic module 20, will only be emitted from the side of the photovoltaic module 20 closest to the frame 10, and the light after passing through the photovoltaic module 20 is relatively soft, improving the viewing comfort for the viewer.

[0049] Optional, Figure 5 This is a cross-sectional structural diagram of another frame provided in an embodiment of the present utility model, with reference to... Figure 2 and Figure 5 In the direction Z perpendicular to the plane where the photovoltaic module 20 is located, the height inside the load receiving groove 12 is h1, and the thickness of the photovoltaic module 20 is h2.

[0050] Wherein, |h1-h2| / h1≤2%.

[0051] Specifically, by setting the height h1 inside the load receiving groove 12 to satisfy |h1-h2| / h1≤2% with the thickness h2 of the photovoltaic module 20, the load receiving groove 12 and the photovoltaic module 20 have the same height or are basically the same height, thereby improving the overall flatness of the photovoltaic floor tile 100. There is no need to set a higher or lower load receiving groove 12 for the load 50, thereby improving the structural compactness of the photovoltaic floor tile 100.

[0052] Optional, Figure 6 A schematic diagram of a photovoltaic module provided in an embodiment of this utility model is shown below. Figure 6 As shown, the photovoltaic module 20 includes a supporting backsheet layer 201, a photovoltaic panel 202, and a glass panel 203; the photovoltaic panel 202 is located between the supporting backsheet layer 201 and the glass panel 203.

[0053] The glass panel 203 includes glass materials such as float glass or tempered glass, and the supporting back panel layer 201 may also include materials such as float glass or tempered glass. These can be set according to actual needs, and no specific limitation is made here.

[0054] Specifically, the photovoltaic panel 202 converts sunlight into electrical energy, making it environmentally friendly and clean. The glass panel 203 has good impact resistance and bending strength. By placing the glass panel 203 on one side of the photovoltaic panel 202, it avoids excessive stress on the photovoltaic panel 202, which could lead to malfunctions and protect the photovoltaic panel 202. The supporting backsheet layer 201 has good mechanical strength and toughness, preventing mechanical stress generated during the installation of the photovoltaic floor tiles 100 from damaging the photovoltaic panel 201. It provides structural support for the photovoltaic panel 201, protecting it, improving its operational reliability, and extending its service life.

[0055] Understandably, to improve the light transmittance through the glass panel 203, an anti-reflective coating can be applied to the surface of the glass panel 203 facing away from the photovoltaic panel 202. This reduces the amount of light reflected by the glass panel 203, increases the light intensity received by the photovoltaic panel 202, and thus improves the photoelectric efficiency of the photovoltaic panel 202. Furthermore, when the photovoltaic floor tile 100 is used in a trampling scenario, the surface of the glass panel 203 facing away from the photovoltaic panel 202 can be frosted or sandblasted to improve the anti-slip properties of the glass panel 203 and ensure the safety of those walking on it.

[0056] Optional, continue to refer to Figure 2 The frame 10 also includes a fastener fixing cavity 15 located on the side of the base plate 13 opposite to the photovoltaic module 20.

[0057] Fasteners include bolts or nuts, which can be set according to actual needs, and no specific limitations are made here.

[0058] Specifically, by setting a fastener fixing cavity 15 on the side of the base plate 13 away from the photovoltaic module 20, the photovoltaic floor tile 100 can be fixed in certain scenarios when it is necessary to use fasteners to install the photovoltaic floor tile 100. This allows the photovoltaic floor tile 100 to not only be laid on a flat surface, but also fixed in other application scenarios, such as fixed above streetlights, thereby improving the practicality and multi-scenario applicability of the photovoltaic floor tile 100.

[0059] Optionally, the control device 40 includes a remote radio frequency transceiver.

[0060] The remote radio frequency transceiver equipment includes Bluetooth modules or Wi-Fi modules, which can be configured according to actual needs; no specific limitations are made here.

[0061] Specifically, by installing a remote radio frequency transceiver within the control device 40, communication with an external remote control terminal can be achieved. The control device 40 is electrically connected to the energy storage device 30 and can collect parameters such as the electrical signals currently transmitted from the photovoltaic module 20 to the energy storage device 30, and the remaining power of the energy storage device 30. These parameters are then transmitted to the remote control terminal via the remote radio frequency transceiver, allowing operation and maintenance personnel to monitor the real-time operating status of the photovoltaic floor tile 100. Operation and maintenance personnel can also adjust the operating parameters of the photovoltaic floor tile 100 based on the parameters provided by the control device 40. For example, when the remaining power of the energy storage device 30 is low, the operation can be modified to stop the energy storage device 30 from supplying power to the load 50, or the energy storage device 30 can be controlled to supply power to the load 50 within a preset time period to ensure the load 50 operates normally. Thus, by installing a remote radio frequency transceiver within the control device 40, the management intelligence of the photovoltaic floor tile 100 is improved, and the system's operational safety is enhanced.

[0062] Understandable Figure 1 The image only shows a top view of the photovoltaic floor tile 100, which is a quadrilateral structure. In practical applications, the structure of the photovoltaic floor tile 100 can be set to hexagonal or octagonal shapes to blend with the actual environment and improve the viewing experience. Furthermore, the materials used to prepare the photovoltaic floor tile 100 in this application are all waterproof and leak-proof, thus improving the safety of the photovoltaic floor tile 100 in use.

[0063] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
