Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to photovoltaic floor tiles. Background Technology

[0002] Photovoltaics is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. Its core component is the photovoltaic panel, which consists of photovoltaic cells, glass, EVA film, a backsheet, a frame, and a junction box. During production, the cells are placed between two layers of EVA film, covered with glass and a backsheet to form a laminate. This laminate is then placed in a laminator and subjected to heating, vacuuming, and pressurization processes to melt and solidify the EVA film, tightly bonding all components together. Finally, the junction box is installed and secured. Photovoltaic power generation has significant advantages; it is a clean energy source, producing no greenhouse gases or pollutants during the power generation process, making it environmentally friendly.

[0003] Photovoltaic paving tiles are an innovative product that combines photovoltaic power generation technology with the function of paving tiles. They resemble ordinary paving tiles in appearance and can seamlessly integrate into various ground environments, such as park trails, plazas, and parking lots. Their working principle is based on the photovoltaic effect; the surface of the paving tile is covered with high-efficiency photovoltaic cells. Under sunlight, these cells convert light energy into electrical energy. The generated electricity can be stored in built-in batteries or directly supplied to surrounding electrical equipment, such as streetlights, landscape lights, and surveillance cameras, achieving self-sufficiency and reducing dependence on the traditional power grid.

[0004] In practical use, photovoltaic floor tiles are attractive to children who are naturally curious about their surroundings. As a new type of floor paving material, photovoltaic floor tiles differ in appearance from ordinary floor tiles and may incorporate some technological elements, which can attract children's attention and stimulate their desire to explore and experience them. As a result, children may run and jump on photovoltaic floor tiles. Currently, some photovoltaic floor tiles have relatively simple designs and lack shock absorption functions, which may cause irreversible damage to the photovoltaic floor tiles when children run and jump. Therefore, photovoltaic floor tiles were proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing photovoltaic floor tiles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The photovoltaic floor tile includes a photovoltaic module. The bottom of the photovoltaic module is provided with a first shock-absorbing component and a second shock-absorbing component. The first shock-absorbing component includes a damping rod, on which a first shock-absorbing spring and a second shock-absorbing spring are installed. The first shock-absorbing spring is used for shock absorption of light weights, and the second shock-absorbing spring is used for shock absorption of heavy weights. The second shock-absorbing component includes a sliding rod, on which a third shock-absorbing spring is symmetrically installed. The third shock-absorbing spring is used to assist the first and second shock-absorbing springs in shock absorption.

[0008] The above technical solution further includes:

[0009] The photovoltaic module includes a metal support frame, within which are arranged sequentially a front tempered glass panel, a first PVB layer, a cell module, a second PVB layer, a third PVB layer, and a back tempered glass panel. The front tempered glass panel, the first PVB layer, the cell module, the second PVB layer, the third PVB layer, and the back tempered glass panel are die-cast together using a laminator.

[0010] The first damping component also includes a base, a damping rod fixedly connected to the top of the base, a top seat fixedly connected to the top of the damping rod, and the top seat installed at the bottom of the metal support frame.

[0011] A sliding ring is slidably mounted on the damping rod. A first damping spring is fixedly connected between the sliding ring and the top seat, and a second damping spring is fixedly connected between the sliding ring and the damping rod. A limit ring is fixedly connected to the outer side of the damping rod.

[0012] The second shock absorption assembly also includes symmetrical support bases, with two support bases fixedly connected to the slide rod, and sliders symmetrically slidably mounted on the slide rod.

[0013] A retaining ring is fixedly connected to the slide rod, and a third damping spring is fixedly connected between the retaining ring and the slide rod.

[0014] The bottom of the metal support frame is symmetrically fixed with two sets of fixed seats, each set containing two seats. The fixed seats and the slider are rotatably connected by a rotating arm.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the first shock-absorbing component includes a first shock-absorbing spring designed for light-weight shock absorption, such as the light footsteps of a child, which effectively cushions minor daily impacts and prevents the photovoltaic module from loosening or damaging internal components due to frequent minor vibrations. The second shock-absorbing spring is used for heavy-weight shock absorption, such as when an adult steps on it or when heavy objects are placed on it. It can withstand greater pressure and prevent the photovoltaic module from breaking due to excessive compression.

[0017] In this invention, the third damping spring, which is symmetrically installed on the slide rod of the second damping component, can assist the first and second damping springs in their work. When the impact force is large, the third damping spring can share part of the pressure, making the entire damping system more stable. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-5As shown, the photovoltaic floor tile proposed in this utility model includes a photovoltaic module. A first shock-absorbing component and a second shock-absorbing component are provided at the bottom of the photovoltaic module. The first shock-absorbing component includes a damping rod 21, on which a first shock-absorbing spring 23 and a second shock-absorbing spring 25 are installed. The first shock-absorbing spring 23 is used for shock absorption of small weights, and the second shock-absorbing spring 25 is used for shock absorption of large weights. The second shock-absorbing component includes a sliding rod 3, on which a third shock-absorbing spring 35 is symmetrically installed. The third shock-absorbing spring 35 is used to assist the first shock-absorbing spring 23 and the second shock-absorbing spring 25 in shock absorption.

[0027] Furthermore, when the photovoltaic floor tiles are subjected to external pressure, the pressure is first transmitted to the bottom of the photovoltaic modules, triggering the response of the first damping component. The damping rod 21, as a core component, has a first damping spring 23 and a second damping spring 25 mounted on it that operate in stages according to the magnitude of the pressure.

[0028] In the low-weight damping stage: when the pressure is small, the first damping spring 23 is compressed first. Its elastic coefficient is small, which can quickly absorb small vibrations and avoid fatigue damage to the photovoltaic module caused by small impacts. At the same time, the damping rod 21 suppresses the resonance when the spring rebounds through the internal damping medium, ensuring a smooth damping process.

[0029] Heavy-weight damping stage: When the pressure exceeds the load-bearing threshold of the first damping spring 23, the second damping spring 25 begins to work. This spring has a larger elastic coefficient and can withstand greater deformation. It forms a series buffer structure with the first damping spring 23 to jointly disperse the pressure and prevent damage to the photovoltaic module due to excessive compression. The damping rod 21 further suppresses high-frequency vibration and improves damping efficiency under the synergistic effect of the two springs.

[0030] Furthermore, the slide bar 3 of the second damping component provides auxiliary support and dynamic balance through the third damping spring 35. The slide bars 3 are symmetrically distributed on both sides of the photovoltaic module. The third damping spring 35 installed on them undergoes symmetrical deformation under pressure, generating a lateral restoring force to counteract lateral displacement caused by uneven pressure, ensuring that the photovoltaic module always remains horizontal. In addition, the elastic coefficient of the third damping spring 35 is between that of the first damping spring 23 and the second damping spring 25, providing a transition buffer when the two springs switch operating states, preventing the damping system from generating impact loads due to sudden pressure changes, thereby extending the service life of the photovoltaic module and the damping structure.

[0031] The photovoltaic module includes a metal support frame 1, within which are arranged sequentially a front tempered glass 10, a first PVB layer 11, a cell module 12, a second PVB layer 13, a third PVB layer 14, and a back tempered glass 15. The front tempered glass 10, the first PVB layer 11, the cell module 12, the second PVB layer 13, the third PVB layer 14, and the back tempered glass 15 are die-cast into one piece using a laminator.

[0032] Furthermore, the front tempered glass 10 serves as a light-transmitting layer, with its high light transmittance (typically ≥91%) ensuring that sunlight penetrates undamaged to the surface of the solar cell, protecting the internal structure from external damage. The first PVB layer 11 and the second PVB layer 13 serve as optical-grade adhesive films, forming a viscoelastic buffer layer during lamination through molecular chain cross-linking. On the one hand, they fill the microscopic gaps between the glass and the solar cell; on the other hand, their high elongation at break (≥200%) absorbs the deformation stress caused by thermal expansion and contraction, preventing interlayer delamination. The solar cell module 12 consists of multiple monocrystalline / polycrystalline solar cells. Silicon solar cells are connected in series by solder ribbons. The surface grid design optimizes the collection efficiency of photogenerated carriers. When sunlight shines on them, electron-hole pairs in the silicon-based material are separated under the action of the built-in electric field of the PN junction, forming a direct current output. The third PVB layer 14 and the tempered glass backsheet 15 constitute a composite backsheet. The PVB layer provides water vapor barrier (water vapor transmittance < 0.1 g / m²·day) and insulation performance, while the backsheet glass enhances mechanical strength and prevents material aging caused by ultraviolet rays. The two work together to protect the solar cell module 12 from environmental corrosion.

[0033] The first shock absorption assembly also includes a base 2, a damping rod 21 fixedly connected to the top of the base 2, and a top seat 20 fixedly connected to the top of the damping rod 21. The top seat 20 is installed at the bottom of the metal support frame 1.

[0034] A sliding ring 24 is slidably mounted on the damping rod 21. A first damping spring 23 is fixedly connected between the sliding ring 24 and the top seat 20. A second damping spring 25 is fixedly connected between the sliding ring 24 and the damping rod 21. A limit ring 22 is fixedly connected to the outer side of the damping rod 21.

[0035] Furthermore, the module uses base 2 as a fixed base, and damping rod 21 is vertically installed on the top of the base. Its top is rigidly connected to the metal support frame 1 of the photovoltaic module through top seat 20, ensuring that the pressure is directly transmitted to the damping system. The surface of damping rod 21 is designed with limit ring 22 and sliding ring 24, wherein the limit ring 22 is fixed in the lower middle part of damping rod 21, serving as the lower limit of deformation for the first damping spring 23 and the second damping spring 25;

[0036] Furthermore, the sliding ring 24 can slide axially along the damping rod 21. Its upper end is connected to the top seat 20 via the first damping spring 23, and its lower end is connected to the base 2 via the second damping spring 25, forming a double-spring graded buffer structure. When the photovoltaic module is subjected to pressure, the pressure is transmitted to the first damping spring 23 through the top seat 20, causing it to compress first. Because the first damping spring 23 has a small elastic coefficient, it can quickly absorb small vibrations. At the same time, the damping medium (such as silicone oil) inside the damping rod 21 consumes the spring rebound energy through shearing action, suppressing high-frequency oscillations. When the pressure exceeds the load-bearing threshold of the first damping spring 23, the sliding ring 24 moves downward and contacts the limiting ring 22. At this time, it triggers the compression of the second damping spring 25 (which has a larger elastic coefficient), forming a series buffer with the first damping spring 23 to jointly disperse the large load. After the pressure is released, the damping force of the damping rod 21 and the spring restoring force work together to reset the sliding ring 24 to its initial position, ensuring the long-term stability of the damping system.

[0037] The second shock absorption assembly also includes a support base 33 for symmetrical devices. The two support bases 33 are fixedly connected to the slide rod 3. Slider 34 are symmetrically slidably arranged on the slide rod 3.

[0038] A retaining ring 32 is fixedly connected to the slide rod 3, and a third damping spring 35 is fixedly connected between the retaining ring 32 and the slide block 34;

[0039] The bottom of the metal support frame 1 is symmetrically fixed with two sets of fixed seats 30. Each set of fixed seats 30 has two seats. The fixed seats 30 and the slider 34 are rotatably connected by a rotating arm 31.

[0040] Furthermore, the component is rigidly fixed to the external structure at both ends of the slide rod 3 via the support seat 33 to ensure the axial stability of the slide rod 3. A retaining ring 32 is fixedly installed in the middle of the slide rod 3 as the installation reference for the third damping spring 35. A slider 34 is slidably installed on the surface of the slide rod 3. The slider 34 and the retaining ring 32 are elastically connected through the third damping spring 35 to form a double-sided symmetrical buffer structure.

[0041] Furthermore, two sets of fixed seats 30 (two in each set) are symmetrically installed at the bottom of the metal support frame 1 of the photovoltaic module. The fixed seats 30 and the slider 34 are hinged together by a rotating arm 31. The rotating arm 31 can rotate freely around the hinge point between the fixed seats 30 and the slider 34 to form a linkage mechanism.

[0042] Furthermore, the third damping spring 35 can assist the first damping spring 23 and the second damping spring 25 in damping, changing the vertical movement of the first damping spring 23 and the second damping spring 25 into the horizontal movement of the third damping spring 35. When the edge of the photovoltaic module is subjected to force, the module transmits the force to the rotating arm 31 through the fixed seat 30, driving the slider 34 to slide along the axis of the slide rod 3, compressing the third damping spring 35 on one side and stretching the third damping spring 35 on the other side.

[0043] In this embodiment, through the mechanical linkage and functional complementarity of the first and second damping components, vertical-lateral composite damping, dynamic leveling, and efficient energy dissipation of the photovoltaic modules are achieved, significantly improving the structural reliability of the photovoltaic floor tiles under complex working conditions.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
