Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic tiles, specifically to a guard plate assembly structure, an outer frame component and photovoltaic tiles. Background Art

[0002] Photovoltaic tiles are a building material that integrates photovoltaic modules into tiles. They are primarily used in roof structures and are incorporated into the roof from the initial stages of construction, replacing conventional tiles. Each tile is connected to a distribution board by cables, where a converter converts the generated energy into electricity to power the building. While retaining the rainproof, windproof, and heat-insulating properties of traditional tiles, they also incorporate the photovoltaic power generation capabilities of traditional tiles. They are also simple to install, using the same installation method as traditional cement and ceramic tiles, and possess high mechanical strength, effectively handling the normal construction and subsequent maintenance of photovoltaic integrated roofs.

[0003] Existing photovoltaic tiles typically consist of a photovoltaic panel and an outer frame assembly to secure the panel. For rectangular photovoltaic tiles, the outer frame assembly typically includes four guard plates, which surround the photovoltaic panel in sequence. Adjacent guard plates are secured together using L-shaped brackets and screws.

[0004] However, the existing photovoltaic tiles still have the following defects: (1) During the on-site installation process, waterproofing treatment is required between two laterally adjacent photovoltaic tiles, and the existing technology usually requires a water guide trough to be set below the two laterally adjacent photovoltaic tiles to drain the water that enters between the two laterally adjacent photovoltaic tiles; however, this method requires the water guide trough to be installed and fixed separately, and it is necessary to ensure the assembly accuracy between the two laterally adjacent photovoltaic tiles and the water guide trough, and a water retaining structure is also required to be set between the photovoltaic tiles and the water guide trough, which has a complex structure, high installation difficulty and low 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

[0029] The present application also provides a photovoltaic tile, comprising a photovoltaic panel and the outer frame assembly.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] (1) Since the first connecting member includes a support frame formed on the left side of the outer frame assembly, a first water baffle extends upward from the left side of the support frame; and since the second connecting member includes a cover plate formed on the right side of the outer frame assembly, the cover plate is located above the first water baffle, and a second water baffle extends downward from the right side of the cover plate; therefore, when two adjacent photovoltaic tiles on the left and right (i.e., two laterally adjacent outer frame assemblies) are docked with each other, a drainage trough can be formed between the support frame and the first water baffle; under the action of the cover plate and the second water baffle, rainwater can only enter the drainage trough through the gap between the second water baffle and the outer frame assembly on the right side. Since the photovoltaic tiles are installed on the roof surface at a downward tilt, the water entering the drainage trough will be discharged downward.

[0032] (2) Since the distance between the lower end of the second water baffle and the cover plate is equal to the distance between the cover plate and the upper side of the support frame, when two adjacent photovoltaic tiles on the left and right (i.e., two laterally adjacent outer frame components) are docked with each other, the lower end of the second water baffle will contact the upper side of the support frame, thereby dividing the drainage trough into two left and right areas, preventing rainwater entering the drainage trough from crossing the first water baffle due to splashing or large amount, thereby causing water leakage, and having stronger waterproof ability.

[0033] (3) Combining the above advantages, that is, the present application only requires the installation and fixing of the photovoltaic tiles (i.e., the outer frame assembly), and no structure needs to be installed between the two laterally adjacent photovoltaic tiles. The overall structure is simpler, the installation is more convenient, and the installation efficiency is high. In addition, since the photovoltaic tiles are modular products and cannot be cut on site according to the actual size requirements, in order to adapt to different roof sizes, the spacing between the two laterally adjacent photovoltaic tiles can be adjusted so that the roof can be covered with an integer number of photovoltaic tiles. At this time, when the spacing between the two laterally adjacent photovoltaic tiles increases or decreases, only the spacing between the second water retaining plate and the outer frame assembly on the right side will be changed adaptively, and will not cause any impact on the waterproofing between them, and has strong versatility.

[0034] (4) In addition to the above-mentioned beneficial effects, the outer frame assembly provided in this application also has the following beneficial effects:

[0035] When the outer frame assembly is spliced ​​using the guard plate connector, the connection between the left guard plate and the front guard plate, as well as the connection 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, which also increases the operational safety.

[0036] Under the action of the protrusion, when the connecting arm is inserted into the insertion cavity, the protrusion is used to increase the resistance to relative sliding between the connecting arm and the insertion cavity, thereby making the connection between the connecting arm and the insertion cavity more firmly, thereby facilitating the improvement of the stability and firmness of the mutual connection between the guard plates;

[0037] In the prior art, the surface of the guard plate is usually treated with a process such as baking, spray painting, 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 cause friction, causing the paint surface to be damaged, thereby forming an equipotential body between the connecting arm and the corresponding two guard plates, that is, they are mutually conductive to achieve full-watt conductivity, thereby ensuring good safety in use when only single-point grounding is used. Otherwise, if there is no conductivity between the two adjacent guard plates due to the insulation of the paint surface, 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 conductivity between the leakage point and the grounding wire, and the safety of use cannot be fully guaranteed, posing a major safety hazard.

[0038] (5) The beneficial effects of the photovoltaic tiles provided in this application are the same as those of the outer frame assembly and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Example 1

[0062] Reference Figures 1 to 9 The present application provides a guard plate assembly structure 1 for assembling two laterally adjacent outer frame assemblies 2; the guard plate assembly structure 1 includes a first connecting member 11 arranged on the left side of the outer frame assembly 2 and a second connecting member 12 arranged on the right side of the outer frame assembly 2; the first connecting member 11 includes a support frame 111 formed on the left side of the outer frame assembly 2, and a first water baffle 112 extends upward from the left side of the support frame 111; the second connecting member 12 includes a cover plate 121 formed on the right side of the outer frame assembly 2, the cover plate 121 is located above the first water baffle 112, and a second water baffle 122 extends downward from the right side of the cover plate 121, and the distance between the lower end of the second water baffle 122 and the cover plate 121 is equal to the distance between the cover plate 121 and the upper side of the support frame 111.

[0063] The working principle of the guard plate assembly structure: Figures 7 to 9 As shown, when two adjacent photovoltaic tiles 100 on the left and right (i.e., two laterally adjacent outer frame components 2) are docked with each other, a drainage trough can be formed between the support frame 111 and the first water baffle 112; under the action of the cover plate 121 and the second water baffle 122, rainwater can only enter the drainage trough through the gap between the second water baffle 122 and the right outer frame component 2. Since the photovoltaic tiles 100 are installed on the roof surface at a downward tilt, the water entering the drainage trough will be discharged downward.

[0064] Since the distance between the lower end of the second water baffle 122 and the cover plate 121 is equal to the distance between the cover plate 121 and the upper side of the support frame 111, when the two adjacent photovoltaic tiles 100 on the left and right (that is, the two laterally adjacent outer frame components 2) are docked with each other, the lower end of the second water baffle 122 will contact the upper side of the support frame 111, thereby dividing the drainage trough into two left and right areas, preventing rainwater entering the drainage trough from splashing or crossing the first water baffle 112 due to large amount, thereby causing leakage, and having stronger waterproof ability.

[0065] That is to say, the present application only requires the installation and fixation of the photovoltaic tiles 100 (i.e., the outer frame assembly 2), and no structural installation is required between two laterally adjacent photovoltaic tiles 100. The overall structure is simpler, the installation is more convenient, and the installation efficiency is high. In addition, since the photovoltaic tiles 100 are modular products and cannot be cut on site according to actual size requirements, in order to adapt to different roof sizes, the spacing between two laterally adjacent photovoltaic tiles 100 can be adjusted so that the roof can be covered with an integer number of photovoltaic tiles 100. At this time, when the spacing between two laterally adjacent photovoltaic tiles 100 increases or decreases, only the spacing between the second water retaining plate 122 and the right outer frame assembly 2 will be adaptively changed, and will not cause any impact on the waterproofing between them, and has strong versatility.

[0066] Reference Figure 9 In some embodiments of the present application, the distance between the left side of the first water retaining plate 112 and the left side of the outer frame assembly 2 is equal to the distance between the right side of the second water retaining plate 122 and the right side of the outer frame assembly 2. When the spacing between two laterally adjacent photovoltaic tiles 100 assemblies is minimized, the first water retaining plate 112 contacts the right side of the left outer frame assembly 2, and the second water retaining plate 122 contacts the left side of the right outer frame assembly 2. This can increase the spacing between two laterally adjacent photovoltaic tiles 100 and improve the water conduction capacity of the drainage trough.

[0067] Reference Figure 9 In some embodiments of the present application, in order to further improve the waterproof capability, at least one first water baffle 113 is provided on the upper side of the support frame 111 and between the first water baffle 112 and the outer frame assembly 2 at intervals on the left and right, and the first water baffle 113 is located below the cover plate 121.

[0068] Reference Figure 9 In some embodiments of the present application, similarly, in order to further improve the waterproof capability, at least one second water baffle 123 is provided on the left and right sides of the lower side of the cover plate 121 and between the outer frame assembly 2 and the second water baffle 122, and the lower end of the second water baffle 123 is flush with the lower end of the second water baffle 122.

[0069] Reference Figure 9In some embodiments of the present application, in order to reduce the influence of the first water baffle 113 and the second water baffle 123 on the spacing adjustment between two laterally adjacent photovoltaic panels 3, when the support frame 111 on the left side of the right outer frame assembly 2 contacts the right side of the left outer frame assembly 2, the second water baffle 122 on the right side of the left outer frame assembly 2 contacts the left side of the right outer frame assembly 2, and the first water baffle 113 fits with the corresponding second water baffle 123.

[0070] Example 2

[0071] Reference Figure 1 and Figure 2 The present application also provides an outer frame assembly 2, including the guard plate assembly structure 1 in Example 1.

[0072] Reference Figure 2 In some embodiments of the present application, the outer frame assembly 2 includes a left guard plate 21, a right guard plate 22, a front guard plate 23 and a rear guard plate 24; Figure 3 and Figure 4 As shown, the left side of the left guard plate 21 and the right side of the right guard plate 22 are both extended upward with outer plates 211, and the upper parts of the two outer plates 211 are extended with upper side plates 212 toward each other, and the left side plate and the corresponding upper side plate 212, the outer plate 211 and the right guard plate 22 and the corresponding upper side plate 212, the outer plate 211 are surrounded by mounting grooves 213; the left and right ends of the rear guard plate 24 (as shown in FIG. Figure 10 and Figure 11 As shown) and the left and right ends of the photovoltaic panel 3 (as shown Figure 5 and Figure 6 As shown) are respectively installed in the two installation slots 213.

[0073] Reference Figure 9 In some embodiments of the present application, in order to prevent rainwater on the cover plate 121 from entering the gutter and to improve aesthetics, the cover plate 121 is kept flush with the upper side plate 212 .

[0074] Reference Figure 6 as well as Figure 11In 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 glue-locking section 214. During actual installation, the mounting groove 213 is filled with a colloid (such as glass glue), which can quickly fix the photovoltaic panel 3 and the rear guard plate 24. Under the action of the glue-locking 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 glue-locking 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 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 is protruded 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.

[0075] Reference Figure 18 In some embodiments of the present application, a front side panel 231 extends upward from the front side of the front guard plate 23, and the upper end of the front side panel 231 is lower than the upper surface of the photovoltaic panel 3, or the upper end of the front side panel 231 is flush with the upper surface of the photovoltaic panel 3. During installation, the photovoltaic panel 3 and the front side panel 231 are preferably fixed and sealed by a colloid (such as glass glue). By making the upper end of the front side panel 231 lower than the upper surface of the photovoltaic panel 3, or by keeping the upper end of the front side panel 231 flush with the upper surface of the photovoltaic panel 3, dust and water are prevented from accumulating on the upper surface of the photovoltaic panel 3. To avoid affecting the aesthetics, the height difference H between the upper end of the front side panel 231 and the upper surface of the photovoltaic panel 3 is preferably 1 mm.

[0076] Reference Figure 10 、 Figure 11 as well as Figure 17 In some embodiments of the present application, a support portion 241 is provided on the underside of the rear guard plate 24 for supporting the photovoltaic panel 3. The support portion 241 improves the stability of the rear side of the photovoltaic panel 3. The photovoltaic panel 3 and the rear guard plate 24 are preferably secured and sealed using a colloid (e.g., glass glue). The support portion 241 is preferably integrally formed with the rear guard plate 24.

[0077] Reference Figure 3 、 Figure 4 、 Figure 12 and Figure 13 In 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.

[0078] Reference Figure 3 、 Figure 4 as well as Figures 12 to 15 In some embodiments of the present application, the guard plate connector 25 includes two connecting arms 251, one ends of the two connecting arms 251 are connected to each other and form a 90° angle; the other ends of the two connecting arms 251 are respectively inserted into two adjacent plug-in cavities 216; at least one outer wall of the connecting arm 251 and / or at least one inner wall of the plug-in cavity 216 is protruded with a protrusion 252; 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 that contacts 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.

[0079] like Figure 15 As shown, the working principle of the guard plate connector 25 is as follows: when the outer frame assembly 2 is spliced ​​using the guard plate connector 25, the connection between the left guard plate 21 and the front guard plate 23, as well as the connection between the right guard plate 22 and the front guard plate 23, can be quickly achieved under the action of the two connecting arms 251. 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, which increases the safety of operation.

[0080] Under the action of the protrusion 252, when the connecting arm 251 is inserted into the insertion cavity 216, the protrusion 252 is used to increase the resistance to relative sliding between the connecting arm 251 and the insertion cavity 216, thereby making the connection between the connecting arm 251 and the insertion cavity 216 more firmly, thereby facilitating the improvement of the stability and firmness of the connection between the guard plates.

[0081] In the prior art, the surface of the guard plate is usually treated by baking, spraying, or coloring, which results in the surface of the guard plate 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, thereby forming an equipotential body between the connecting arm 251 and the corresponding two guard plates, that is, they are mutually conductive to achieve full-watt conductivity, thereby ensuring good safety in use when only single-point grounding is used. Otherwise, if the two adjacent guard plates are not conductive due to the insulation of the paint surface, 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 conductivity between the leakage position and the grounding wire, and the safety of use cannot be fully guaranteed, posing a major safety hazard.

[0082] Reference Figure 3 、 Figure 4 as well as Figures 12 to 15In some embodiments of the present application, the protrusion 252 is a long strip of 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 insertion of 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 contact area 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 also facilitates one-piece molding.

[0083] Reference Figure 15 In some embodiments of the present application, in order to further improve the effect of the protrusion 252, 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 1mm-2mm.

[0084] In some embodiments of the present application, the tooth tip structure within the plug-in cavity 216 is located on a side close to the internal 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 provided with a slope structure 217 with an angle of 45°. The slope structure 217 is used to make the outer end of the tooth tip structure within the plug-in cavity 216 form a sharp angle 2521, and the front end of the left guard plate 21 and the left end of the front guard plate 23, as well as the front end of the right guard plate 22 and the right end of the front guard plate 23 are complemented by two corresponding slope structures 217.

[0085] Reference Figure 15 In some embodiments of the present application, two connecting arms 251 are provided with angled structures 253 at ends facing away from each other. The sharp corners 2521 provide a better ability to damage the protrusions 252 on the connecting arms 251. The two adjacent inclined structures 217 complement each other at the joints between the adjacent guard plates.

[0086] Reference Figure 13 In some embodiments of the present application, a material removal trough 254 is provided on the connecting arm 251. This can save the amount of the connecting arm 251 and thus reduce costs.

[0087] Reference Figure 12 In some embodiments of the present application, a sealing strip 26 is provided along the length of the underside of the front guard plate 23. This sealing strip 26 can improve the waterproofing of the overlapping portions of the photovoltaic tiles 100. The present application does not limit the specific structure of the sealing strip 26; only two specific structures are provided below for reference.

[0088] Structure 1: Reference Figures 16 to 18The 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 underside of the front guard plate 23, and the annular sealing portion 262 is connected to the underside of the first fixing portion 261. Under the weight of the photovoltaic tile 100 itself, the annular sealing portion 262 is compressed, ensuring a seal and adapting to installation errors.

[0089] Structure 2: Reference Figure 19 The cross-section of the sealing strip 26 includes a second fixing portion 263, a transverse section 264, and two diagonal sections 265. The second fixing portion 263 is connected to the underside of the front guard plate 23; the transverse section 264 is connected to the underside of the second fixing portion 263. The upper ends of the two diagonal sections 265 are connected to the two ends of the transverse section 264, and the two diagonal sections 265 are arranged in a "perfect eight" shape. This centrosymmetrical design of the sealing strip 26 not only provides shock absorption but also provides good support. The two diagonal sections 265 in the "perfect eight" shape can be placed stably on the upper surface of the photovoltaic panel 3. After being squeezed, the two diagonal sections 265 are completely attached to the lower photovoltaic tile 100 (i.e., the upper surface of the photovoltaic panel 3). When two diagonal sections 265 are overlapped, they also provide a dual waterproofing effect, preventing water from penetrating the overlapping area. Furthermore, the sealing strip 26 is the same length as the front guard plate 23 to prevent water from penetrating the overlapping area. Similarly, the two diagonal sections 265 can also be arranged in an "inverted eight" shape.

[0090] like Figure 18 and Figure 19 As shown, it should be understood that 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.
