Technical Field

[0001] The present application relates to the technical field of photovoltaic tiles, and specifically to a guard plate connector, 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.

[0028] Compared with the prior art, the beneficial effects of this application are:

[0029] (1) The guard plate connector provided in the present application, under the action of the two connecting arms, when it is necessary to splice and fix two adjacent guard plate bodies on the outer frame assembly, it is only necessary to insert the ends of the two connecting arms that are away from each other into the plug-in cavities at the ends of the two adjacent guard plate bodies, so as to achieve the splicing and fixation between the two adjacent guard plate bodies. Compared with the traditional fixing method, the installation and fixing method of the present application is simpler and more convenient to operate, has a higher installation efficiency, and does not require screwing during operation, so the operation safety is also higher.

[0030] (2) Under the action of the protrusion, when the connecting arm is inserted into the plug-in cavity, the protrusion is used to increase the resistance to relative sliding between the connecting arm and the plug-in cavity, thereby making the connecting arm and the plug-in cavity more firmly stuck, which is beneficial to improving the stability and firmness of the mutual connection between the two adjacent guard plate bodies.

[0031] (3) In the prior art, the surface of the guard plate body is usually treated by baking, spraying or coloring, which results in the surface of the guard plate body 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 the connecting arm and the corresponding two guard plate bodies form an equipotential body, that is, the two adjacent guard plate bodies can be connected through the guard plate connector, and the whole watt can be conductive, which makes it easy to have good safety when only single-point grounding is used. Otherwise, if the two adjacent guard plate bodies are not conductive due to paint insulation, that is, the whole watt cannot be conductive, 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, which poses a great safety hazard.

[0032] (4) The beneficial effects of the outer frame assembly and the photovoltaic tile provided in the present application are the same as the beneficial effects of the guard plate connector, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. The terms "including" and "having" in the specification and claims of the present application and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0057] Reference Figure 1 , Figure 2 as well as Figures 5 to 10 One embodiment of the present application provides a guard plate connector 1 for connecting two adjacent guard plate bodies 21 (such as Figure 5 As shown); the guard plate connecting member 1 includes two connecting arms 11, one end of the two connecting arms 11 is connected to each other and forms an angle, and the other end of the two connecting arms 11 is respectively inserted into the insertion cavity 211 at the end of the two guard plate bodies 21 (as shown Fig.10 As shown in Figure 2 , Figure 7 and Fig. 9 As shown, at least one outer side wall of the connecting arm 11 and / or at least one inner side wall of the inserting cavity 211 is provided with a protruding portion 111 .

[0058] like Fig.10 As shown, when the connecting arm 11 is inserted into the plug-in cavity 211, the protrusion 111 and the part contacting the protrusion 111 cause the paint surface to be damaged due to friction, so that the connecting arm 11 and the corresponding two guard plate bodies 21 form an equipotential body; when the connecting arm 11 is inserted into the plug-in cavity 211, the protrusion 111 is used to increase the resistance to relative sliding between the connecting arm 11 and the plug-in cavity 211.

[0059] The working principle of the guard plate connector 1 is as follows: Fig.10 As shown, under the action of the two connecting arms 11, when it is necessary to realize splicing and fixing of two adjacent guard plate bodies 21 on the outer frame assembly 2, it is only necessary to insert the ends of the two connecting arms 11 that are far away from each other into the plug-in cavities 211 at the ends of the two adjacent guard plate bodies 21, respectively, so as to realize the splicing and fixing between the two adjacent guard plate bodies 21. 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 operation safety.

[0060] Under the action of the protrusion 111, when the connecting arm 11 is inserted into the plug-in cavity 211, the protrusion 111 is used to increase the resistance to relative sliding between the connecting arm 11 and the plug-in cavity 211, thereby making the connecting arm 11 and the plug-in cavity 211 more firmly stuck, which is beneficial to improving the stability and firmness of the mutual connection between the two adjacent guard plate bodies 21.

[0061] In addition, since the surface of the guard plate body 21 is usually treated by baking, spraying or coloring, the surface of the guard plate body 21 is in an insulating state. However, under the action of the protrusion 111, when the connecting arm 11 is inserted into the plug-in cavity 211, the protrusion 111 and the part that contacts the protrusion 111 cause the paint surface to be damaged due to friction, so that the connecting arm 11 and the corresponding two guard plate bodies 21 form an equipotential body, that is, the two adjacent guard plate bodies 21 can be connected through the guard plate connector 1, and the whole watt can be conductive, so that it is convenient to still have good safety when only single-point grounding is used. Otherwise, if the two adjacent guard plate bodies 21 are not conductive due to paint insulation, that is, the whole watt cannot be conductive, if single-point grounding is used at this time, there is a situation where there is no conductivity between the leakage position and the grounding wire, and the safety of use cannot be fully guaranteed, and there is a great safety hazard.

[0062] In some embodiments of the present application, in order to improve the effect of the protrusion 111, a protrusion 111 is provided on at least one outer wall of the connecting arm 11, and a protrusion 111 is provided on at least one inner wall of the insertion cavity 211 opposite to the protrusion 111 on the connecting arm 11.

[0063] It is understandable that if Figure 1 and Figure 2 As shown, for example, a protrusion 111 is provided on an outer side wall of the connecting arm 11, and a protrusion 111 is also provided on the inner side wall opposite to the protrusion 111 in the plug-in cavity 211, so that the two contact surfaces opposite to the connecting arm 11 and the plug-in cavity 211 have protrusions 111, thereby improving the interaction effect of the protrusions 111, for example, the protrusions 111 are denser, can provide greater resistance, and have a better effect on damaging the paint surface.

[0064] It should be understood that the present application does not limit the number of protrusions 111 on the outer wall of the connecting arm 11 or the inner wall of the plug-in cavity 211 , and any number may be set according to actual needs, and the protrusions 111 are preferably arranged at equal intervals.

[0065] In addition, the present application does not limit the specific structure of the protrusion 111, and only provides a preferred structure as follows: Figure 2 , Figure 7 as well as Fig. 9 As shown, the protrusion 111 is preferably a strip-shaped tooth tip structure. The tooth tip structure is convenient for improving the damage effect on the paint surface, and the strip-shaped structure is convenient for integrated processing and molding.

[0066] In order to further improve the effect of the protrusions 111 on the two opposite contact surfaces of the connecting arm 11 and the plug-in cavity 211, the length direction of the tooth tip structure on the connecting arm 11 is intersected with the length direction of the tooth tip structure in the plug-in cavity 211, that is, by making the protrusions 111 on the two opposite contact surfaces of the connecting arm 11 and the plug-in cavity 211 cross each other, in the process of inserting the connecting arm 11 into the plug-in cavity 211, the protrusions 111 on the connecting arm 11 and the protrusions 111 in the plug-in cavity 211 contact with 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.

[0067] Reference Fig.10 In some embodiments of the present application, in order to facilitate processing and molding, the length direction of the tooth tip structure in the plug-in cavity 211 is parallel to the length direction of the corresponding guard plate body 21, so as to facilitate the integral molding of the protrusion 111 while molding the guard plate body 21. The length direction of the tooth tip structure on the connecting arm 11 is perpendicular to the length direction of the tooth tip structure in the corresponding plug-in cavity 211, that is, the length direction of the tooth tip structure is along the thickness direction of the connecting arm 11, which is convenient for demolding during molding; in addition, compared with making the relative protrusions 111 intersect obliquely, when they are perpendicular (i.e., orthogonal), the area of ​​the contact surface between the protrusions 111 can be further reduced.

[0068] Reference Fig.10 In some embodiments of the present application, in order to further improve the effect of the protrusions 111, the overlapping thickness D between the tooth tip structure on the connecting arm 11 and the tooth tip structure in the corresponding plug-in cavity 211 is preferably 1mm-2mm.

[0069] Reference Figures 5 to 10 In some embodiments of the present application, the tooth tip structure in the plug-in cavity 211 is located on a side close to the inner direction of the outer frame assembly 2, and an inclined surface structure 212 is provided on the end of the guard plate body 21 corresponding to the connecting arm 11, and the inclined surface structure 212 is used to form a sharp angle 1111 (such as Fig.10 As shown), and the two adjacent inclined structures 212 are used to make the ends of the two adjacent guard plate bodies 21 complementary (as shown Figure 4 as shown).

[0070] It should be understood that if Fig.10 As shown, under the action of the sharp corner 1111, the sharp corner 1111 has a better effect of destroying the protrusion 111 on the connecting arm 11. Figure 3 and Figure 4 As shown, under the action of two adjacent inclined structures 212, the joints between two adjacent guard plate bodies 21 complement each other.

[0071] It can be understood that the angle of the inclined structure 212 and the angle between the two connecting arms 11 need to be set according to the shape of the outer frame component 2. For example, when the outer frame component 2 is rectangular, the angle of the inclined structure 212 is 45°, and the angle between the two connecting arms 11 is 90°.

[0072] Reference Figure 1 and Fig.10 In some embodiments of the present application, an angled structure 112 is provided at one end of the two connecting arms 11 that is away from each other. The angled structure 112 facilitates the insertion of the connecting arms 11 into the insertion cavity 211 .

[0073] Reference Figure 1 In some embodiments of the present application, a material removal trough 113 is provided on the connecting arm 11. By providing the material removal trough 113, the usage of the connecting arm 11 can be saved, thereby reducing the cost.

[0074] The present application also provides an outer frame assembly 2, including at least three guard plate bodies 21, each guard plate body 21 is spliced ​​together to enclose an area for fixing the photovoltaic panel 3, and at least two adjacent guard plate bodies 21 are connected by a guard plate connector 1.

[0075] Reference Figures 3 to 12 In some embodiments of the present application, the number of the guard plate bodies 21 is four, which are used to enclose the outer frame assembly 2 of the rectangular structure. The guard plate body 21 located on the left side of the photovoltaic panel 3 and the guard plate body 21 located on the front side of the photovoltaic panel 3, as well as the guard plate body 21 located on the right side of the photovoltaic panel 3 and the guard plate body 21 located on the front side of the photovoltaic panel 3 are connected by the guard plate connector 1; Figure 6 , Fig.11 , Fig.12 , Fig.14 as well as Fig.15 As shown, the upper sides of the guard plate body 21 located on the left side of the photovoltaic panel 3 and the guard plate body 21 located on the right side of the photovoltaic panel 3 are both provided with outer plates 213 upwards, and upper side plates 214 extend toward each other from the upper parts of the two outer side plates 213, and an installation groove 210 is formed between the upper side plate 214, the outer side plate 213 and the guard plate body 21; the left and right ends of the photovoltaic panel 3 and the guard plate body 21 located on the rear side of the photovoltaic panel 3 are respectively installed in the two installation grooves 210.

[0076] Reference Fig.11 and Fig.16 In some embodiments of the present application, a support portion 215 for supporting the photovoltaic panel 3 is provided on the lower side of the guard plate body 21 located at the rear side of the photovoltaic panel 3. The support portion 215 can improve the support stability of the rear side of the photovoltaic panel 3. The photovoltaic panel 3 and the guard plate body 21 at the rear side of the photovoltaic panel 3 are suitable for being fixed and sealed by a colloid (such as glass glue). Among them, the support portion 215 is preferably integrally formed with the guard plate body 21 at the rear side of the photovoltaic panel 3.

[0077] Reference Fig.12 In some embodiments of the present application, the two ends of the support portion 215 are respectively in contact with or fixed to the guard plate body 21 on the left side of the photovoltaic panel 3 and the guard plate body 21 on the right side of the photovoltaic panel 3; of course, it can also be connected through the guard plate connector 1, and at this time the support portion 215 has a plug-in cavity 211 structure.

[0078] Reference Fig.12 , Fig.14 as well as Fig.15 In some embodiments of the present application, colloid is filled between the mounting groove 210 and the photovoltaic panel 3 and between the mounting groove 210 and the corresponding guard plate body 21, and the side of the upper side plate 214 away from the outer side plate 213 is gradually bent downward to form a locking glue section 2141. Among them, the photovoltaic panel 3 and the mounting groove 210 and the guard plate body 21 and the mounting groove 210 can be quickly fixed by the colloid (such as glass glue), and under the action of the locking section, the colloid in the mounting groove 210 can be prevented from overflowing, thereby reducing the amount of colloid; at the same time, the locking glue section 2141 itself can also reduce the internal space of the mounting groove 210, thereby also reducing the amount of colloid; in addition, after the colloid is solidified, there is more colloid near the inside of the mounting groove 210 and less colloid near the exit position of the mounting groove 210, which can also increase the anti-separation ability between the colloid and the mounting groove 210 and help reduce the cracking phenomenon of the colloid.

[0079] Reference Fig.12 , Fig.14 as well as Fig.15 In some embodiments of the present application, a glue locking portion 2142 is protruded from the lower side of the glue locking section 2141 and / or the lower side of the upper side plate 214 and / or the lower side of the junction between the glue locking section 2141 and the upper side plate 214. Under the action of the glue locking portion 2142, the effect of preventing the colloid from overflowing can be further improved, while reducing the amount of colloid used and improving the bonding strength of the colloid.

[0080] Reference Fig.16 as well as Fig.17 In some embodiments of the present application, a front side plate 216 is provided on the upper side of the guard plate body 21 located on the front side of the photovoltaic panel 3; the upper end of the front side plate 216 is lower than the upper surface of the photovoltaic panel 3, or the upper end of the front side plate 216 is flush with the upper surface of the photovoltaic panel 3. During installation, the photovoltaic panel 3 and the front side plate 216 are suitable for being fixed and sealed by a colloid (such as glass glue). By making the upper end of the front side plate 216 lower than the upper surface of the photovoltaic panel 3, or the upper end of the front side plate 216 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 216 and the upper surface of the photovoltaic panel 3 is preferably 1 mm. For the sake of aesthetics, the front side plate 216 is preferably formed by extending upward along the front side of the corresponding guard plate body 21.

[0081] Reference Figure 8 as well as Fig.17 In some embodiments of the present application, a sealing strip 22 is provided along the length direction on the lower side of the guard plate body 21 located on the front side of the photovoltaic panel 3. Figures 18 to 20 As shown, under the action of the sealing strip 22, when the two photovoltaic tiles 100 are overlapped, the front part of the upper inclined photovoltaic tile 100 is pressed against the rear part of the lower inclined photovoltaic tile 100. At this time, the sealing strip 22 plays a role of sealing and waterproofing, preventing rainwater from penetrating into the overlapping area through the gap between the upper and lower photovoltaic tiles 100.

[0082] It should be understood that the present application does not limit the specific structure of the sealing strip 22 , and only two specific structures are provided below for reference, see Example 1 and Example 2 for details.

[0083] Embodiment 1: Fig. 20 As shown, the cross section of the sealing strip 22 includes a first fixing portion 221 and an annular sealing portion 222. The first fixing portion 221 is connected to the lower side of the guard plate body 21 on the front side of the photovoltaic panel 3, and the annular sealing portion 222 is connected to the lower side of the first fixing portion 221. Under the gravity of the photovoltaic tile 100 itself, the annular sealing portion 222 is compressed, which can ensure sealing and adapt to installation errors.

[0084] Embodiment 2: Fig.21 As shown, the cross-section of the sealing strip 22 includes a second fixed portion 223, a transverse section 224 and two oblique sections 225. The second fixed portion 223 is connected to the lower side of the guard plate body 21 on the front side of the photovoltaic panel 3; the transverse section 224 is connected to the lower side of the second fixed portion 223, and the upper ends of the two oblique sections 225 are respectively connected to the two ends of the transverse section 224, and the two oblique sections 225 are distributed in a "straight eight" shape or an "inverted eight" shape.

[0085] In the second embodiment, the two oblique sections 225 are preferably distributed in a "perfect eight" shape, and the angle between the oblique section 225 and the transverse section 224 is 135°. This centrally symmetrically designed sealing strip 22 provides good support for the assembly while playing a role in buffering and shock absorption, so that the assembly can be placed stably on a plane. At the same time, the sealing strip 22 is the same length as the guard plate body 21, and the oblique sections 225 on both sides are completely attached to the next photovoltaic tile 100 after being squeezed, and can also play a double waterproof role when overlapped, preventing water from penetrating into the overlap area.

[0086] It should be understood that there is no limit to the installation method of the first fixing portion 221 and the second fixing portion 223. For example, a method of embedding and fixing in a groove may be adopted. In this case, the first fixing portion 221 or the second fixing portion 223 is suitable for a T-shaped structure, which is completely embedded in the groove, plays a good fixing role, and prevents the sealing strip 22 from falling off.

[0087] Reference Fig.13 The present application also provides a photovoltaic tile 100, including a photovoltaic panel 3 and an outer frame assembly 2, and the outer frame assembly 2 is used to fix the photovoltaic panel 3, so that they form a whole photovoltaic tile 100.
