Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic tiles, and specifically to a quick-install fixture, an outer frame assembly and a photovoltaic tile. Background Art

[0002] Photovoltaic tiles are a type of building material that integrates photovoltaic module units into tiles. They are mainly used for roof structures and are used as part of the roof in the early stages of construction, replacing conventional tiles. Each photovoltaic tile is connected to the distribution board by a cable and converts the generated energy into electricity through a converter to provide electricity for the interior of the building. Photovoltaic tiles retain the rainproof, windproof, and heat-insulating properties of traditional tiles, while giving traditional tiles the properties of photovoltaic power generation. They are easy to install and have the same installation method as traditional cement tiles and ceramic tiles. They also have high mechanical strength and can effectively cope with the normal construction and subsequent maintenance of photovoltaic integrated roofs.

[0003] Existing photovoltaic tiles usually include photovoltaic panels and an outer frame assembly for fixing the photovoltaic panels. For photovoltaic tiles with a rectangular structure, the outer frame assembly usually includes four guard plate bodies, which are sequentially surrounded by the photovoltaic panel, and two adjacent guard plate bodies need to be fixedly connected by L-shaped angle brackets and screws.

[0004] However, the existing photovoltaic tiles still have the following defects: (1) During the on-site installation process, in order to adapt to the traditional roof structure (i.e., inclined structure), the photovoltaic tiles need to be stacked and fixed in sequence from bottom to top along the inclined direction of the roof, that is, the front end of the upper photovoltaic tile overlaps the rear end of the lower photovoltaic tile, so that rainwater can be drained downward along the photovoltaic tiles in sequence; in the prior art, in order to achieve the above-mentioned installation effect, it is usually necessary to adopt a complex installation structure and fix it with screws, which is difficult to install and has low installation efficiency. In addition, the stability after installation is not high and the effect of resisting wind force is limited; in addition, after installation and fixation, due to differences in roof structure or errors in screw installation, the position of the photovoltaic tiles may need to be adjusted in the horizontal or inclined direction. At this time, the installed photovoltaic tiles need to be reinstalled, which further increases the difficulty of installation and reduces the installation efficiency.

[0005] (2) Since two adjacent guard plate bodies need to be installed and fixed with L-shaped angle brackets and screws, the actual installation process is time-consuming and labor-intensive, with low installation efficiency. In addition, it is easy to prick or scratch the hands when manually installing the screws with an electric screwdriver, posing a safety hazard. Summary of the invention

[0026] The present application also provides a photovoltaic tile, comprising a photovoltaic panel and the outer frame assembly.

[0027] Compared with the prior art, the beneficial effects of this application are:

[0028] (1) The quick-install fixing part has a simple structure. When used to fix two overlapping photovoltaic tiles, it is only necessary to install and fix the mounting part on the hanging part on the lower side of the photovoltaic tile, and install the connecting plate and / or the supporting plate on the stopper on the tile hanging strip. When the two photovoltaic tiles are overlapped, the upper surface of the supporting plate is used to support the photovoltaic tile located below, and the photovoltaic tile located above and the hanging part are used to clamp the photovoltaic tile located below and the limiting plate. In other words, when installing, it is only necessary to overlap the front end of the upper photovoltaic tile on the upper side of the rear end of the lower photovoltaic tile, and then push the upper photovoltaic tile downward along the slope of the roof surface, so that the hanging part and the limiting plate can be hung and matched, which is convenient to install and has high installation efficiency. After installation, the front end of the upper photovoltaic tile and the rear end of the lower photovoltaic tile form a whole and are effectively fixed on the same tile hanging strip, which has high stability and strong wind resistance.

[0029] (2) Since there is no limit between the hanging part and the limiting plate on the plane parallel to the limiting plate (i.e., the roof surface), the position of the photovoltaic tiles can still be fine-tuned along the lateral or inclined direction of the roof surface after installation and fixation. It is only necessary to fix the photovoltaic tiles on the outermost edge of the roof surface at the end, which makes the installation more convenient and more practical.

[0030] (3) In addition to the above-mentioned beneficial effects, the outer frame assembly provided by the present application also has the following beneficial effects:

[0031] When the outer frame assembly is spliced ​​with the guard plate connector, the connection between the left guard plate and the front guard plate and between the right guard plate and the front guard plate can be quickly achieved under the action of the two connecting arms. Compared with the traditional fixing method, the installation and fixing method of the present application is simpler and more convenient to operate, with higher installation efficiency, and no screws are required during the operation, so the operation safety is also higher;

[0032] Under the action of the protrusion, when the connecting arm is inserted into the inserting cavity, the protrusion is used to increase the resistance to relative sliding between the connecting arm and the inserting cavity, so that the connecting arm and the inserting cavity are more firmly stuck, which is beneficial to improve the stability and firmness of the mutual connection between the guard plates;

[0033] In the prior art, the surface of the guard plate is usually treated by baking, spraying or coloring, which results in the guard plate surface being in an insulating state. However, under the action of the protrusion, when the connecting arm is inserted into the plug-in cavity, the protrusion and the part in contact with the protrusion are damaged by friction, so that an equipotential body is formed between the connecting arm and the corresponding two guard plates, that is, they are mutually conductive to achieve full-watt conductivity, so that they can still have good safety when only single-point grounding is used. Otherwise, if there is no conduction between two adjacent guard plates due to paint insulation, that is, full-watt conductivity cannot be achieved, if single-point grounding is used at this time, there will be a situation where there is no conduction between the leakage position and the grounding wire, and the safety of use cannot be fully guaranteed, which poses a great safety hazard.

[0034] (4) The beneficial effects of the photovoltaic tiles provided in the present application are the same as the beneficial effects of the outer frame assembly and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Embodiment 1

[0058] Reference Figures 1 to 6The present embodiment provides a quick-install fixture 1 for fixing and overlapping two photovoltaic tiles 100; the quick-install fixture 1 includes a hanging member 11 and a stopper 12; the hanging member 11 includes a mounting portion 111, a connecting portion 112 and a hanging portion 113, the mounting portion 111 is mounted on the lower side of the photovoltaic tile 100, the upper end of the connecting portion 112 is connected to the mounting portion 111, and the lower end of the connecting portion 112 is connected to the hanging portion 113; the stopper 12 includes a support plate 121, a connecting plate 112, and a support plate 113. 22 and a limit plate 123, the upper end of the connecting plate 122 is connected to the rear end of the supporting plate 121, the lower end of the connecting plate 122 is connected to the front end of the limit plate 123, the connecting plate 122 and / or the supporting plate 121 are installed on the tile hanging strip; when two photovoltaic tiles 100 are overlapped, the upper surface of the support plate 121 is used to support the photovoltaic tile 100 located below, and the photovoltaic tile 100 located above and the hanging part 113 are used to clamp the photovoltaic tile 100 located below and the limit plate 123.

[0059] The working principle of the quick-release fixture 1: the quick-release fixture 1 has a simple structure. When used to fix and overlap two photovoltaic tiles 100, it is only necessary to install and fix the mounting portion 111 on the hanging member 11 on the lower side of the photovoltaic tile 100, and install the connecting plate 122 and / or the support plate 121 on the stopper 12 on the tile hanging strip; because when the two photovoltaic tiles 100 are overlapped, the upper surface of the support plate 121 is used to support the photovoltaic tile 100 located below, and the photovoltaic tile 100 located above and the hanging portion 113 are used to clamp the photovoltaic tile 100 located below and the limit plate 123. That is to say, during installation, it is only necessary to overlap the front end of the upper photovoltaic tile 100 on top of the rear end of the lower photovoltaic tile 100, and then push the upper photovoltaic tile 100 downward along the slope of the roof surface, so that the hanging part 113 and the limiting plate 123 can be hung and matched, which is convenient for installation and high in installation efficiency. After installation, the front end of the upper photovoltaic tile 100 and the rear end of the lower photovoltaic tile 100 form a whole and are effectively fixed on the same tile hanging strip, with high stability and strong wind resistance.

[0060] In addition, since there is no limitation between the hanging portion 113 and the limiting plate 123 on the plane parallel to the limiting plate 123 (i.e., the roof surface), the position of the photovoltaic tile 100 can still be fine-tuned along the lateral or inclined direction of the roof surface after installation and fixation. It is only necessary to fix the photovoltaic tile 100 at the outermost edge of the roof surface at the end, which makes the installation more convenient and more practical.

[0061] Reference Figure 1 as well as Figure 6In some embodiments of the present application, the distance L between the connection portion 112 and the front side of the photovoltaic tile 100 is less than or equal to the length of the rear guard plate 24 on the photovoltaic tile 100 along the front-to-back direction, and the distance L between the connection portion 112 and the front side of the photovoltaic tile 100 is greater than or equal to half of the length of the rear guard plate 24 along the front-to-back direction. When the front end of the upper photovoltaic tile 100 overlaps the upper rear end of the lower photovoltaic tile 100, the upper rear end of the lower photovoltaic tile 100 will be blocked. If L is greater than the length of the rear guard plate 24 along the front-to-back direction, when the rear end of the lower photovoltaic tile 100 contacts the connection portion 112, the upper photovoltaic tile 100 will block the photovoltaic panel 3 on the lower photovoltaic tile 100, thereby affecting the power generation efficiency. However, when L is less than half of the length of the rear guard plate 24 along the front-to-back direction, when the rear end of the lower photovoltaic tile 100 contacts the connection portion 112, the overlap area of ​​the upper photovoltaic tile 100 and the lower photovoltaic tile 100 is limited, thereby affecting the stability of the overlap. Therefore, after comprehensive consideration, the best choice is when the distance L between the connecting portion 112 and the front side of the photovoltaic tile 100 is equal to the length of the rear guard plate 24 on the photovoltaic tile 100 along the front-to-back direction; at this time, the overlap area of ​​the upper photovoltaic tile 100 and the lower photovoltaic tile 100 is the largest, the stability is the highest, and the photovoltaic panel 3 will not be blocked. At this time, the rear end of the limit plate 123 should not exceed the rear end of the lower photovoltaic tile 100; the rear end of the limit plate 123 is preferably kept flush with the rear end of the lower photovoltaic tile 100.

[0062] Reference Figure 3 as well as Figure 4 In some embodiments of the present application, the mounting portion 111 and the hanging portion 113 are both plate-shaped structures; the connecting portion 112 includes a first vertical plate 1121 and a second vertical plate 1122, the upper ends of the first vertical plate 1121 and the second vertical plate 1122 are connected to the mounting portion 111 at intervals; the side of the first vertical plate 1121 away from the second vertical plate 1122 is kept flush with the front side of the mounting portion 111; the lower end of the second vertical plate 1122 is gradually bent to connect with the lower end of the first vertical plate 1121, and then extends to connect with the front end of the hanging portion 113, and the rear end of the hanging portion 113 is connected to the side of the first vertical plate 1121 away from the second vertical plate 1122. Through this structure, the dead weight and cost of the structure can be reduced under the premise of improving the structural strength and installation stability.

[0063] Reference Figure 3 In some embodiments of the present application, the connection portion 112 further includes a reinforcing plate 1123 , and the reinforcing plate 1123 is connected between the first vertical plate 1121 and the second vertical plate 1122 to further improve the strength of the connection portion 112 .

[0064] Embodiment 2

[0065] Reference Figure 2 as well as Fig. 9The present embodiment provides an outer frame assembly 2, including a left guard plate 21, a right guard plate 22, a front guard plate 23 and a rear guard plate 24, which are connected to each other and enclose an area for fixing the photovoltaic panel 3; the outer frame assembly 2 also includes the quick-install fixing member 1 in the first embodiment, and the lower sides of the left guard plate 21 and the right guard plate 22 are provided with a hanging member 11 on the quick-install fixing member 1. The quick-install fixing member 1 facilitates the overlap and fixation of two outer frame assemblies 2 (i.e., two photovoltaic tiles 100).

[0066] Reference Figure 3 , Fig.10 as well as Fig.11 In some embodiments of the present application, the left guard plate 21 and the right guard plate 22 are both hollow structures, and the lower sides of the left guard plate 21 and the right guard plate 22 are bent upward to form an inverted V-shaped structure 210. The inverted V-shaped structure 210 is formed by being recessed into the hollow structure, and will not occupy the external space, so as not to affect the installation and fixation of the mounting portion 111; at the same time, when the mounting portion 111 is fixed to the lower side of the left guard plate 21 or the rear guard plate 24 (i.e., the inverted V-shaped structure 210) by screws, the inverted V-shaped structure 210 can fully improve the bonding strength between the screws and ensure the installation firmness of the mounting portion 111.

[0067] Reference Fig.10 as well as Fig.11 In some embodiments of the present application, the left side of the left guard plate 21 and the right side of the right guard plate 22 are both extended upward with an outer side plate 211, and the upper parts of the two outer side plates 211 are both extended with upper side plates 212 toward each other, and the left side plate and the corresponding upper side plate 212, the outer side plate 211 and the right guard plate 22 and the corresponding upper side plate 212, the outer side plate 211 are surrounded by mounting grooves 213; the left and right ends of the rear guard plate 24 (such as Fig.15 As shown) and the left and right ends of the photovoltaic panel 3 (as shown Fig.12 and Fig.13 As shown in the figure, the photovoltaic panel 3 and the rear guard plate 24 are respectively installed (for example, by glass glue) in two installation grooves 213. The installation grooves 213 facilitate the installation and fixation of the photovoltaic panel 3 and the rear guard plate 24.

[0068] Reference Fig.13 as well as Fig.15In some embodiments of the present application, the side of the upper side plate 212 away from the outer side plate 211 is gradually bent downward to form a locking glue section 214. During actual installation, the mounting groove 213 is filled with colloid (such as glass glue), and the photovoltaic panel 3 and the rear guard plate 24 can be quickly fixed by the colloid. Under the action of the locking glue section 214, the colloid in the mounting groove 213 can be prevented from overflowing, thereby reducing the amount of colloid used; at the same time, the locking glue section 214 itself can also reduce the internal space of the mounting groove 213, thereby also reducing the amount of colloid used; in addition, after the colloid is solidified, there is more colloid near the inside of the mounting groove 213, and less colloid near the exit position of the mounting groove 213, which can also increase the anti-separation ability between the colloid and the mounting groove 213 and help reduce the cracking of the colloid. Furthermore, a glue locking portion 215 protrudes from the lower side of the glue locking section 214 and / or the lower side of the upper side plate 212 and / or the lower side of the junction between the glue locking section 214 and the upper side plate 212 to further improve the effect of preventing the colloid from overflowing, while reducing the amount of colloid used and improving the bonding strength of the colloid.

[0069] Reference Figure 7 as well as Fig.16 In some embodiments of the present application, a front side plate 231 is extended upward from the front side of the front guard plate 23, and the upper end of the front side plate 231 is lower than the upper surface of the photovoltaic panel 3, or the upper end of the front side plate 231 is flush with the upper surface of the photovoltaic panel 3. During installation, the photovoltaic panel 3 and the front side plate 231 are suitable for being fixed and sealed by a colloid (such as glass glue). By making the upper end of the front side plate 231 lower than the upper surface of the photovoltaic panel 3, or the upper end of the front side plate 231 is flush with the upper surface of the photovoltaic panel 3, it is ensured that dust and water will not accumulate on the upper surface of the photovoltaic panel 3. In order not to affect the aesthetics, the height difference H between the upper end of the front side plate 231 and the upper surface of the photovoltaic panel 3 is preferably 1 mm.

[0070] Reference Fig.14 In some embodiments of the present application, a support portion 241 for supporting the photovoltaic panel 3 is provided on the lower side of the rear guard plate 24. The support portion 241 can improve the support stability of the rear side of the photovoltaic panel 3. The photovoltaic panel 3 and the rear guard plate 24 are suitable for being fixed and sealed by a colloid (such as glass glue). Among them, the support portion 241 is preferably integrally formed with the rear guard plate 24.

[0071] Reference Fig.10 , Fig.11 as well as Figures 16 to 19In some embodiments of the present application, a plug-in cavity 216 is formed inside the left guard plate 21, the right guard plate 22 and the front guard plate 23, and the two adjacent plug-in cavities 216 on the left guard plate 21 and the front guard plate 23 and the two adjacent plug-in cavities 216 on the right guard plate 22 and the front guard plate 23 are connected by a guard plate connector 25; the guard plate connector 25 includes two connecting arms 251, one end of the two connecting arms 251 is connected to each other and forms a 90° angle; the two connecting arms 251 The other end is respectively plugged into two adjacent plug-in cavities 216; a protrusion 252 is protruded from at least one outer wall of the connecting arm 251 and / or at least one inner wall of the plug-in cavity 216; when the connecting arm 251 is inserted into the plug-in cavity 216, the paint surface is damaged due to friction between the protrusion 252 and the part contacting the protrusion 252; after the connecting arm 251 is inserted into the plug-in cavity 216, the protrusion 252 is used to increase the resistance to relative sliding between the connecting arm 251 and the plug-in cavity 216.

[0072] The working principle of the guard plate connecting member 25 is as follows: Fig.19 As shown, when the outer frame assembly 2 is spliced ​​using the guard plate connector 25, under the action of the two connecting arms 251, the connection between the left guard plate 21 and the front guard plate 23 and between the right guard plate 22 and the front guard plate 23 can be quickly achieved. Compared with the traditional fixing method, the installation and fixing method of the present application is simpler and more convenient to operate, has higher installation efficiency, and does not require screwing during operation, and has higher operational safety.

[0073] Under the action of the protrusion 252, when the connecting arm 251 is inserted into the plug-in cavity 216, the protrusion 252 is used to increase the resistance to relative sliding between the connecting arm 251 and the plug-in cavity 216, thereby making the connecting arm 251 and the plug-in cavity 216 more firmly stuck, which is beneficial to improving the stability and firmness of the connection between the guard plates.

[0074] In the prior art, the surface of the guard plate is usually treated by baking, spraying or coloring, which results in the guard plate surface being in an insulating state. However, under the action of the protrusion 252, when the connecting arm 251 is inserted into the plug-in cavity 216, the protrusion 252 and the part in contact with the protrusion 252 cause the paint surface to be damaged due to friction, so that an equipotential body is formed between the connecting arm 251 and the corresponding two guard plates, that is, they are mutually conductive to achieve full-watt conductivity, and thus it is convenient to still have good safety in use when only single-point grounding is used. Otherwise, if there is no conduction between the two adjacent guard plates due to paint insulation, that is, full-watt conductivity cannot be achieved, if single-point grounding is used at this time, there will be a situation where there is no conduction between the leakage position and the grounding wire, and the safety of use cannot be fully guaranteed, and there is a great safety hazard.

[0075] Reference Fig.10 , Fig.11 as well as Figures 16 to 19In some embodiments of the present application, the protrusion 252 is a strip-shaped tooth tip structure, the length direction of the tooth tip structure in the plug-in cavity 216 is arranged along the front-to-back direction, and the length direction of the tooth tip structure on the connecting arm 251 is perpendicular to or intersects with the length direction of the tooth tip structure in the corresponding plug-in cavity 216. At this time, during the process of inserting the connecting arm 251 into the plug-in cavity 216, the protrusion 252 on the connecting arm 251 and the protrusion 252 in the plug-in cavity 216 contact each other and produce wear, and the area of ​​mutual contact is smaller, that is, the destructive force is stronger, that is, the ability to damage the paint surface is stronger; at the same time, the bite force between the contact surfaces is greater, thereby providing greater resistance. In addition, this layout method is also convenient for one-piece molding.

[0076] Reference Fig.19 In some embodiments of the present application, the tooth tip structure in the plug-in cavity 216 is located on the side close to the inner direction of the outer frame assembly 2, and the front end of the left guard plate 21, the front end of the right guard plate 22, and the left and right ends of the front guard plate 23 are all provided with a 45° inclined surface structure 217, and the inclined surface structure 217 is used to form a sharp angle 2521 at the outer end of the tooth tip structure in the plug-in cavity 216, and the front end of the left guard plate 21 and the left end of the front guard plate 23, and the front end of the right guard plate 22 and the right end of the front guard plate 23 are complemented by two corresponding inclined surface structures 217. The sharp angle 2521 has a stronger destructive ability and is more conducive to piercing the tooth tip structure on the connecting arm 251.

[0077] Reference Fig.19 In some embodiments of the present application, the overlapping thickness D between the tooth tip structure on the connecting arm 251 and the tooth tip structure in the corresponding plug-in cavity 216 is 1 mm-2 mm.

[0078] Reference Fig.16 In some embodiments of the present application, a sealing strip 26 is provided along the length direction on the lower side of the front guard plate 23. The sealing strip 26 can improve the waterproof ability of the overlapping position of the photovoltaic tile 100. The present application does not limit the specific structure of the sealing strip 26, and only two specific structures are provided below for reference.

[0079] Structure 1: Figure 7 As shown, the cross section of the sealing strip 26 includes a first fixing portion 261 and an annular sealing portion 262. The first fixing portion 261 is connected to the lower side of the front guard plate 23, and the annular sealing portion 262 is connected to the lower side of the first fixing portion 261. Under the gravity of the photovoltaic tile 100 itself, the annular sealing portion 262 is compressed, which can ensure sealing and adapt to installation errors.

[0080] Structure 2: Figure 8As shown, the cross section of the sealing strip 26 includes a second fixing portion 263, a transverse section 264 and two oblique sections 265. The second fixing portion 263 is connected to the lower side of the front guard plate 23; the transverse section 264 is connected to the lower side of the second fixing portion 263, and the upper ends of the two oblique sections 265 are respectively connected to the two ends of the transverse section 264, and the two oblique sections 265 are in the shape of a "regular eight". This kind of sealing strip 26 with a central symmetrical design can provide good support while playing a role in buffering and shock absorption. The two oblique sections 265 of the "regular eight" structure can be stably placed on the upper surface of the photovoltaic panel 3. After being squeezed, the two oblique sections 265 are completely attached to the next photovoltaic tile 100 (i.e., the upper surface of the photovoltaic panel 3). When two are overlapped, they can also play a double waterproof role to prevent water from penetrating into the overlap area. At the same time, the sealing strip 26 is the same length as the front guard plate 23 to prevent water from penetrating into the overlap area. Similarly, the two oblique sections 265 can also be distributed in the shape of an "inverted eight".

[0081] It should be understood that if Figure 7 and Figure 8 As shown, the installation method of the first fixing portion 261 and the second fixing portion 263 is not limited. For example, a method of embedding and fixing in a groove can be adopted. At this time, the first fixing portion 261 or the second fixing portion 263 is suitable for a T-shaped structure, which is completely embedded in the groove, plays a good fixing role, and prevents the sealing strip 26 from falling off.
