Description

Technical Field

[0001] This invention relates to the field of photovoltaic tile installation technology, and in particular to an easy-to-install photovoltaic tile support. Background Technology

[0002] Photovoltaic tiles are building-integrated photovoltaic (BIPV) products that integrate solar cells (crystalline silicon or thin-film technology) directly into roof tiles. They combine the protective functions of traditional roof tiles (waterproof, wind-resistant, load-bearing, and decorative) with photovoltaic power generation capabilities. Photovoltaic tiles look similar to traditional tiles and are laid flush with the roof. Adjacent tiles are electrically connected through pre-installed waterproof plugs at the bottom. They combine the reliability of building materials with the concealment of power generation and are mainly used in high-end residences that emphasize aesthetics, renovations of historical buildings, and commercial projects.

[0003] Photovoltaic tiles are typically electrically interconnected via MC4 connectors integrated at their bottom. The installation process for photovoltaic tiles involves first laying parallel wooden strips along the roof waterproofing layer, then fixing dedicated support bases onto the strips, and finally fixing the photovoltaic tiles onto the support bases and connecting adjacent photovoltaic tiles via connectors to complete the installation of the entire photovoltaic tile roof.

[0004] Because the MC4 connector is located at the bottom of the photovoltaic tile, and the gap between the tile and the roof structure is only 2cm-5cm, workers can only operate the connector blindly by touch and cannot achieve precise visual alignment. This extreme spatial constraint and high-precision docking requirement make the connector insertion and removal process extremely cumbersome, becoming a major bottleneck that seriously restricts the progress of photovoltaic tile installation. Especially when the reserved wiring length is insufficient or the photovoltaic tile size is large, workers also need to overcome the difficulty of insufficient cable slack, which further exacerbates the complexity and difficulty of installation. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the insertion and removal process of the MC4 connector at the bottom of the photovoltaic tile is cumbersome and restricts the installation progress due to space constraints and the requirement for docking accuracy. Therefore, this invention proposes an easy-to-install photovoltaic tile support.

[0006] To achieve the above objectives, the present invention employs the following technology: a photovoltaic tile easy-to-install support base, comprising a base body, wherein a plurality of said base bodies are arranged in parallel at equal intervals, and further comprising:

[0007] A wiring mechanism includes an outer frame disposed between two adjacent bases and whose two ends are pressed and fixed by the bases. A telescopic cylinder is fixed inside the outer frame. A connecting frame is fixed at the top of the telescopic cylinder. Connecting frames are hinged to both sides of the connecting frame. A connecting unit one and a connecting unit two are respectively provided at the ends of the two connecting frames that are far apart.

[0008] After being pressed down by the photovoltaic tile, the connecting frame pushes the connecting unit one and the connecting unit two through the connecting frame. The connecting unit two moves the MC4 female seat at the bottom of the photovoltaic tile to a preset position, and the connecting unit one drives the MC4 male head at the bottom of the photovoltaic tile to connect and lock with the MC4 female seat at the bottom of another photovoltaic tile.

[0009] As a further description of the above technical solution: the second connecting unit includes a frame body two that is hinged to and slidably connected to the connecting frame inside the outer frame, and a second card seat two is slidably connected inside the frame body two.

[0010] As a further description of the above technical solution: the first connecting unit includes a frame body 1 that is hinged to and slidably connected to the connecting frame inside the outer frame, and a card seat 1 is slidably connected inside the second frame body.

[0011] As a further description of the above technical solution: the card holder two is internally slidably connected with two symmetrically arranged unlocking plates, and push rods are fixed on both sides of the inner wall of the frame two.

[0012] As a further description of the above technical solution: the inner wall of the frame is provided with a strip groove.

[0013] As a further description of the above technical solution: both ends of the outer frame are fixed with protrusions, and the bottom of the base is provided with a number of straight, equidistant holes for fitting the protrusions.

[0014] As a further description of the above technical solution: both ends of the connecting frame are provided with square holes for the photovoltaic tile MC4 connector to pass through.

[0015] As a further description of the above technical solution: it also includes a pressure plate assembly, which includes a pressure plate slidably connected to the connecting frame, an elastic locking pin fixed inside the pressure plate, and a locking groove provided on the connecting frame.

[0016] As a further description of the above technical solution: the end of the pressure plate near the connecting frame is bent upwards and tilted upwards.

[0017] In summary, due to the adoption of the above-mentioned technology, the beneficial effects of this invention are:

[0018] 1. Before the photovoltaic tile is placed on the base, the male and female heads of the MC4 connectors at the bottom of the photovoltaic tile are positioned by connecting unit one and connecting unit two, respectively. After the photovoltaic tile is placed on the base, the connectors between adjacent photovoltaic tiles are connected by the gravity of the photovoltaic tile using the connecting frame and connecting bracket. This design not only eliminates the difficulties of space constraints and high connection accuracy requirements in the electrical connection of photovoltaic tiles and simplifies the connection process, but also effectively avoids cable tangling, optimizes cable path utilization, and reduces the requirement for cable reserve length, which is particularly beneficial for the installation and deployment of short cable photovoltaic tiles.

[0019] 2. In this application, connection unit one and connection unit two integrate a dedicated unlocking structure for the MC4 connector. This design allows the locking state between the bottom MC4 connector and the adjacent photovoltaic tile connector to be quickly released without the need for additional tools when a single photovoltaic tile fails and needs to be replaced. This significantly simplifies the disassembly process of the faulty tile, enables the rapid replacement of photovoltaic tiles, and greatly improves the efficiency of subsequent operation and maintenance.

[0020] 3. This application uses a connecting frame and pressure plate to coordinately limit the cable, so that the cable fits the bottom layout of the outer frame. This design effectively avoids the cable hanging and obstructing the heat dissipation airflow inside the outer frame, ensuring the heat dissipation efficiency of the photovoltaic tile. On the other hand, it eliminates the cable swing caused by airflow disturbance, significantly reduces the risk of micro-motion wear between the cable and the photovoltaic tile, and prevents fatigue fracture at the connection, thereby ensuring the long-term reliability of the electrical connection of the photovoltaic tile and the overall operating efficiency.

[0036] The following will describe clearly and completely the technology of a photovoltaic tile easy-to-install support base according to the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-11 As shown, the present invention provides an easy-to-install photovoltaic tile support base: including a base body 10, a plurality of base bodies 10 are arranged in parallel at equal intervals and fixed to the water flow strip by steel nails.

[0038] Reference Figures 1-7To facilitate the alignment and connection of the connectors during photovoltaic tile installation, a wiring mechanism 20 is also included. The wiring mechanism 20 includes an outer frame 21 disposed between two adjacent bases 10 and whose two ends are pressed and fixed by the bases 10. The top and bottom of the outer frame 21 are in contact with the photovoltaic tile and the roof waterproof layer, respectively, and heat dissipation holes are provided on both sides. A telescopic cylinder 23 is fixed inside the outer frame 21. A connecting frame 22 is fixed at the top of the telescopic cylinder 23. The top of the connecting frame 22 is inclined and fits against the bottom surface of the photovoltaic tile. A connecting frame 24 is hinged on both sides of the connecting frame 22. A connecting unit 1 25 and a connecting unit 26 are respectively provided at the ends of the two connecting frames 24 that are far apart.

[0039] During photovoltaic tile installation, the telescopic cylinder 23 extends, causing the connecting frame 22 to be in a raised state. Connecting unit 1 25 and connecting unit 26 are not yet inserted into the bottom of the base 10. At this time, the male and female heads of the MC4 connectors at the bottom of the photovoltaic tile are fixed by connecting unit 1 25 and connecting unit 26 respectively. Then, the photovoltaic tile is placed on the connecting frame 22. The weight of the photovoltaic tile presses down the connecting frame 22. The connecting frame 22 descends vertically under the positioning of the telescopic cylinder 23, which drives the two connecting frames 24 to push connecting unit 1 25 and connecting unit 26 into the bottom of the base 10 on both sides of the photovoltaic tile. This causes the male head to connect with the female head of the downstream photovoltaic tile. The female head moves to the predetermined position, waiting to connect with the male head when the upstream photovoltaic tile is installed.

[0040] Reference Figure 8 The connecting unit 26 includes a frame 261 that is hinged to the connecting frame 24 and slidably connected to the inside of the outer frame 21. A card seat 262 is slidably connected inside the frame 261.

[0041] The connecting unit 25 includes a frame 251 that is hinged to the connecting frame 24 and slidably connected to the inside of the outer frame 21, and a card holder 252 is slidably connected inside the frame 261.

[0042] Card slot 1 252 and card slot 2 262 are respectively provided with grooves for fitting the male and female of the MC4 connector. The two grooves fit into the male and female respectively. After the male and female are embedded in the grooves, there is friction with the inner wall of the grooves, which improves the firmness of the connection between the two. Furthermore, under the limitation of the grooves, the male and female can be angularly aligned, which facilitates the connection.

[0043] It should be noted that after the male and female parts of the MC4 connector are connected, they are locked by two clips on the male part to prevent external force from causing the photovoltaic tiles to break the connection.

[0044] Reference Figure 9 and Figure 10The card holder 262 has two symmetrically arranged unlocking plates 263 slidingly connected inside. The inner walls of the frame 261 are fixed with push rods 264 that pass through the unlocking plates 263. One side of the push rod 264 has a bevel. When the push rod 264 moves, it can move the unlocking plate 263 toward the buckle of the MC4 connector male through the bevel. By pushing the buckle, the male and female are unlocked, which facilitates the disassembly and replacement of photovoltaic tiles.

[0045] The inner wall of frame 251 is provided with an inclined strip groove 253. Similarly, when frame 251 moves, it pushes the unlocking plate 263 through the inner wall of the strip groove 253, which can also unlock the male and female connectors.

[0046] Reference Figure 2 and Figure 6 Since the positions of the bottom cables and connectors of different photovoltaic tiles are different, in order to make the outer frame 21 adapt to the position of the connector and facilitate the fixing of the base 10 to the outer frame 21, both ends of the outer frame 21 are fixed with protrusions 27, and the bottom of the base 10 is provided with several straight and equidistant holes for fitting the protrusions 27.

[0047] According to the position of the bottom cable and connector of the photovoltaic tile, change the position of the outer frame 21, then press the base 10 onto the end of the outer frame 21 and let the protrusion 27 be embedded in the hole. Then fix the base 10 to the water flow strip with steel nails. At this time, the outer frame 21 is firmly fixed to the water flow strip by the base 10 to prevent the outer frame 21 from shifting.

[0048] Reference Figure 6 and Figure 11 Both ends of the connecting frame 24 are provided with square holes for the photovoltaic tile MC4 connector to pass through. The bottom of the connecting frame 24 is hollow for arranging cables. Before fixing the connector to the card holder 252 or card holder 262, the connector is passed through the square hole at one end of the connecting frame 24 near the connecting bracket 22, and then the connector is passed through the other square hole. Finally, the connector is embedded in the groove of the card holder 252 or card holder 262. The purpose of this is that after the connecting frame 24 pushes the connecting unit 25 and the connecting unit 26 to realize the electrical connection between the photovoltaic tiles, it can also limit the cable, so that the cable passes through the bottom of the connecting frame 24, separates the cable from the bottom of the photovoltaic tile and prevents the cable from blocking the internal air duct of the outer frame 21, thereby improving the heat dissipation effect of the photovoltaic tile.

[0049] Reference Figures 5-7 In order to avoid cable swaying caused by airflow disturbance leading to fatigue fracture at the connection between the cable and the photovoltaic tile, a pressure plate assembly 30 is also included. The pressure plate assembly 30 includes a pressure plate 31 slidably connected to the connecting frame 24. The pressure plate 31 supports the photovoltaic tile cable, which can reduce the swaying of the cable and prevent fatigue damage at the connection between the cable and the photovoltaic tile due to swaying.

[0050] The end of the pressure plate 31 near the connecting bracket 22 is bent upwards to prevent damage to the cable when supported.

[0051] The pressure plate 31 has an internally fixed elastic locking pin 32, and the connecting frame 24 has a slot. As the pressure plate 31 slides toward the connecting frame 22, the elastic locking pin 32 continuously inserts into the slot and then disengages from the slot due to its own elasticity. After the pressure plate 31 stops moving, the elastic locking pin 32 inserts into the slot, preventing the pressure plate 31 from sliding in the opposite direction. This design is used to ensure that the pressure plate 31 can only slide in one direction on the connecting frame 24.

[0052] Reference Figure 11 By adjusting the position of the pressure plate 31, the cable can be properly supported according to its length. Specifically, the cable is supported by the pressure plate 31 to prevent it from shaking due to airflow disturbance. It is worth mentioning that in order to prevent the cable tension from pulling the card holder 252 and card holder 262, there is sufficient static friction between the card holder 252 and card holder 262 and the outer frame 21.

[0053] A paddle is fixed on the elastic locking pin 32 to pry up the elastic locking pin 32 so as to readjust the position of the pressure plate 31 and prevent the position of the pressure plate 31 from being over-adjusted.

[0054] Working principle: In the initial state, the telescopic cylinder 23 is in the extended state, the connecting frame 22 rises from above the outer frame 21, and the end of the outer frame 21 near the connecting unit 25 is pressed and fixed by the base body 10. The position of the pressure plate 31 on the connecting frame 24 is adjusted according to the length of the photovoltaic tile cable.

[0055] After inserting the male and female connectors of the MC4 connector at the bottom of the photovoltaic tile through the two square holes of the connecting frame 24, they are embedded into the grooves of the first bracket 252 and the second bracket 262. Then, the photovoltaic tile is placed on the connecting frame 22 and allowed to slowly sink. The downward pressure on the connecting frame 22 causes the connecting frame 24 to push the first frame 251 and the second frame 261. The first frame 251 and the second frame 261 then move the first bracket 252 and the second bracket 262 towards both ends of the outer frame 21, causing the male and female connectors to move. As it descends to contact the outer frame 21, another seat 10 is fitted onto one side of the photovoltaic tile, and the end of the outer frame 21 near the second connecting unit 26 and the end of the other outer frame 21 near the first connecting unit 25 are pressed and fixed. After the photovoltaic tile drives the connecting frame 22 to descend to the lowest point, the first card holder 252 drives the male end to move and insert into the female seat of the downstream photovoltaic tile. The two photovoltaic tiles are electrically connected through the connector. The second card holder 262 drives the female seat to move to the predetermined position, waiting for the upstream photovoltaic tile to be installed and electrically connected to it.

[0056] During the above process, the connecting frame 24 gradually changes from an inclined state to a horizontal state, which drives the pressure plate 31 to support the cable. There is sufficient static friction between the card holder 252 and the card holder 262 and the outer frame 21 so that the cable will not pull the card holder 252 and the card holder 262 through the connector male and female after being supported.

[0057] When it is necessary to disassemble the photovoltaic tile, the base 10 near the end of the connecting unit 26 is disassembled, and the photovoltaic tile is lifted upward. After a gap is created between the photovoltaic tile and the outer frame 21, the connecting frame 22 is lifted upward with a tool so that it moves upward together with the photovoltaic tile. At this time, the upward movement of the connecting frame 22 pulls the frame 251 through the connecting frame 24. The frame 251 squeezes the male head buckle through the strip groove 253, so that the male head is unlocked from the female seat. The frame 251 continues to move, driving the card seat 252 and the male head to move, so that the male head of the photovoltaic tile is disconnected from the downstream photovoltaic tile female seat.

[0058] At the same time, the connecting frame 24 pulls the frame 261, which in turn moves the push rod 264. The push rod 264 pushes the unlocking plate 263 to squeeze the upstream male connector buckle, thus unlocking the upstream photovoltaic tile male connector from the female connector. The frame 261 continues to move, which in turn moves the card holder 262, the unlocking plate 263, the push rod 264, and the female connector, thus disconnecting the photovoltaic tile from the upstream photovoltaic tile male connector, thereby achieving the disassembly of the photovoltaic tile.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's technology and inventive concept, should be covered within the scope of protection of the present invention.
