The frame 110 has a mounting cavity 112, and the long side of the photovoltaic module 120 is embedded in the mounting cavity 112. In some exemplary embodiments, each photovoltaic module 120 has only a long side mounted with the bezel 110 and a short side without the bezel 110. Because the short side of photovoltaic module 120 is on a parallel with the eave, at the easy deposition of short side installation frame 110, so this scheme is exemplary only at the long limit installation frame 110 of photovoltaic module 120 to be difficult to the deposition.

In the present application, the frame of the frame 110 is not limited in structure, and may be configured in a manner known in the art, such as a structure with corner cavities.

As an example, the frame body of the frame 110 is a U-shaped frame body 111, and the U-shaped frame body 111 encloses an installation cavity 112.

For convenience of description, a portion of the U-shaped frame 111 located on the front side of the photovoltaic module 120 is defined as a front frame 1111, and a portion of the U-shaped frame 111 located on the rear side of the photovoltaic module 120 is defined as a rear frame 1113.

The clamping part 320 is used for corresponding to the frame 110; the first connection portion 210 corresponds to the second connection portion 310, and the two connection portions are detachably connected and electrically contacted.

As an example, the photovoltaic module 120 mounting system further includes a fastener 400, the first connecting portion 210 and the second connecting portion 310 are screwed by the fastener 400; of course, in other embodiments, the first connection portion 210 and the second connection portion 310 may be detachably connected by a snap-fit connection or the like.

At least one of the press-fit surface 221 and the outer wall of the front face frame 1111 is provided with a projection structure 1112 for breaking the insulating film.

Referring to fig. 4, in the photovoltaic module lightning protection installation system 10, when the first connection portion 210 and the second connection portion 310 are connected and the pressing surface 221 abuts against the front frame 1111, the clamping portions 320 are located at the back of the frame 110, and the clamping portions 320 and the frame 110 are distributed oppositely and surround the clamping gap 500.

Referring to fig. 5, in the photovoltaic roof 1, the lightning protection wire 50 is exemplarily electrically contacted to the latch 300 through a terminal at an end portion, for example, the terminal is screwed to an end surface of the latch 300 through a bolt, so that the lightning protection wire 50 is electrically connected to the latch 300; the clamping plate 34 is accommodated in the clamping gap 500, the clamping portion 320 extends into the mounting groove 33 and abuts against the bottom of the clamping plate 34, and the frame 110 abuts against the top of the clamping plate 34.

The working principle of the embodiment of the application is as follows:

in the framed photovoltaic assembly 100, the photovoltaic assembly 120 is provided with the frame 110, so that the photovoltaic assembly 120 is convenient to install. The frame 110 is a U-shaped structure, which is simpler than a conventional frame structure provided with corner cavities, and can reduce the cost of the frame 110. Moreover, considering that the long edge is stressed on the long edge of the photovoltaic module 120 after installation, the frame 110 with the short edge can be omitted, which is beneficial to further reducing the cost of the frame 110 and effectively avoiding dust accumulation on the short edge.

In the photovoltaic module lightning protection installation system 10, the clamping portion 320 of the clamping block 300 is arranged opposite to the frame 110, so that the clamping plate 34 of the installation substrate 30 can be conveniently clamped, and the installation can be conveniently realized; the pressing piece 200 is used for pressing the frame 110, and then the pressing piece 200 is detachably connected with the fixture block 300, so that the frame 110 is convenient to mount, fix, dismount and maintain.

At least one of the pressing surface 221 and the outer wall of the front frame 1111 is provided with a protruding structure 1112 for breaking the insulating film, so that the frame 110 and the pressing piece 200 can be well conducted; the first connecting portion 210 is electrically contacted with the second connecting portion 310, so that the pressing member 200 and the latch 300 can be better electrically conducted. This setting mode makes frame 110 can conduct with fixture block 300 better through casting die 200 for lightning protection wire 50 connects when the fixture block 300 carries out the hidden wiring, and frame 110 can conduct with lightning protection wire 50 better.

In the present application, at least one of the press-fit surface 221 and the outer wall of the front housing 1111 is provided with a protruding structure 1112 for breaking the insulating film, and the two can be electrically contacted, and the principle is described by taking the example in which the press-fit surface 221 is provided with the protruding structure 1112: when the pressing surface 221 and the outer wall of the front frame 1111 are pressed, the protruding structure 1112 of the pressing surface 221 contacts the outer wall of the front frame 1111 to break the insulating film of the outer wall of the front frame 1111; since the contact surface of the protruding structure 1112 of the pressing surface 221 with the outer wall of the front frame 1111 is small and the force is large, when the insulating film of the outer wall of the front frame 1111 is broken by the protruding structure 1112, the insulating film of the contact portion of the protruding structure 1112 with the outer wall of the front frame 1111 is also broken.

Further, in the application, the movement of the protrusion 1112 for breaking the insulating film is not limited, and may be, for example, a puncture, a friction, or the like.

As an example, the protrusion 1112 is a protrusion in the form of a sharp contact with the insulation film, ensuring that the insulation film can be punctured more efficiently and reliably.

In the photovoltaic roof 1, the mounting support 20 is arranged for supporting and fixing the lap joint structure 31 of the mounting substrate 30, which is beneficial to improving the bearing performance of the mounting substrate 30 and the wind uncovering resistance of the mounting substrate at two ends. The mounting substrate 30 is provided with a mounting groove 33 with an opening on the side surface for the clamping portion 320 of the fixture 300 to extend into, so that the clamping portion 320 and the frame 110 of the fixture 300 can clamp the clamping plate 34 for mounting.

The lightning protection wire 50 is electrically connected to the fixture block 300, so that the frame 110 is electrically connected to the lightning protection wire 50 sequentially through the pressing member 200 and the fixture block 300, and the wiring is conveniently hidden.

Some exemplary embodiments of the examples of the present application will be further described below.

In the first aspect, based on the consideration of structural stability, service life and the like:

considering that the bezel 110, the mounting substrate 30 and the fixture block 300 are usually made of metal, and they are located in an outdoor environment when the roof is in operation, the chemical corrosion reaction between metals on the contact surface is easily caused by water.

Referring to fig. 4, in order to improve the intermetallic chemical corrosion reaction between the frame 110 and the mounting substrate 30, in some exemplary embodiments, the outer wall of the back frame 1113 is covered with an isolation glue layer 113, and the material of the isolation glue layer 113 is not limited as long as the isolation glue layer can perform the intermetallic chemical corrosion isolation function on the outer wall of the back frame 1113. By covering the outer wall of the rear housing 1113 with the insulating paste layer 113, it is possible to effectively prevent the outer wall of the rear housing 1113 from contacting the mounting board 30 on which it is mounted and causing a chemical corrosion reaction between metals.

As an example, the spacer paste layer 113 is adhesively connected to the outer wall of the rear frame 1113.

With continued reference to fig. 4, to improve the intermetallic chemical corrosion reaction between the clip 300 and the mounting substrate 30, in some exemplary embodiments, the surface of the retention portion 320 facing the retention gap 500 is covered with an isolation layer 330; as an example, the isolation layer 330 is sleeved on the end portion where the holding portion 320 is located. The isolation layer 330 can perform an intermetallic chemical corrosion isolation function on the surface of the clamping portion 320 facing the clamping gap 500, so as to effectively prevent the surface of the clamping portion 320 facing the clamping gap 500 from contacting the mounting substrate 30 where the mounting substrate is mounted to generate an intermetallic chemical corrosion reaction.

Referring to fig. 7, further, the bottom of the second isolation layer 330 is protruded with an isolation protrusion 331, it can be understood that the shape of the isolation protrusion 331 is not limited. The bottom of the second connection portion 310 is further provided with a supporting edge 313, in this way, the lower trace cavity 312 is, for example, in an unclosed form, and the opening thereof is located at the bottom of the second connection portion 310, the supporting edge 313 is, for example, sleeved at the opening of the second connection portion 310, and the material thereof may also be selected to be a material capable of performing an isolation effect of chemical corrosion between metals. The support edge 313 is aligned with the bottom of the separation protrusion 331 to ensure that the latch 300 can be laid flat during temporary support.

In the structure illustrated in fig. 4, the catch 320 is connected to the bottom side wall of the second connecting portion 310 such that the side wall of the second connecting portion 310 is adjacent to the upper surface of the catch 320. This mode of setting for when card holder 320 and frame 110 cooperation carry out the centre gripping to the upper and lower surface of centre gripping plate body 34, the lateral wall of second connecting portion 310 can carry out the butt to the lateral wall outside of frame 110, can improve the stability of installation.

Referring to fig. 8, in consideration of improving the load-bearing performance and wind-lift resistance of the photovoltaic roof 1, in some exemplary embodiments, a support portion 35 is protruded from the middle of the mounting substrate 30, and the support portion 35 abuts against the middle of the back surface of the photovoltaic module.

The middle part of the back of the photovoltaic module 120 is conveniently supported by the support part 35, which is beneficial to improving the support stability of the photovoltaic module 120.

Further, the photovoltaic roofing 1 further comprises a support pedestal 40, and the support pedestal 40 is fixed to the roof 2 by, for example, a screw, a bolt, or the like. The support portion 35 is mounted to the support pedestal 40. The support base 40 is used for supporting and fixing the support portion 35, which is beneficial to further improving the bearing performance of the mounting substrate 30 and improving the wind uncovering resistance of the mounting substrate in the middle.

In order to effectively protect the photovoltaic module 120 while improving the supporting stability of the photovoltaic module 120, as an example, a supporting pad 121 is disposed in the middle of the back surface of the photovoltaic module 120, and the supporting pad 121 extends along the long side direction of the photovoltaic module 120, that is, the length direction of the supporting pad 121 is parallel to the long side direction of the photovoltaic module 120. The supporting pad 121 is disposed corresponding to the supporting portion 35, and in the photovoltaic roof 1, the top of the supporting portion 35 abuts against the bottom of the supporting pad 121.

In a second aspect, the following considerations in terms of conduction, lightning protection, wiring, etc.:

in some exemplary embodiments, two adjacent bridging structures 31 form a rolled-up lockstitching structure 32 when mounted to the mounting bracket 20. The distance from the top of the lockstitching structure 32 to the roof is greater than the distance from the top of the photovoltaic module lightning protection installation system 10 to the roof, i.e., the lockstitching structure 32 is higher than the photovoltaic module lightning protection installation system 10. This arrangement makes lockstitching a border structure 32 can receive the direct lightning earlier, can strengthen the lightning protection effect to the mounting system.

In the photovoltaic roofing 1, the length of the mounting substrate 30 is generally long, and each mounting substrate 30 is connected with a plurality of photovoltaic modules 120 side by side in the length direction, the length direction of the plurality of photovoltaic modules 120 corresponds to the length direction of the mounting substrate 30, and the width direction of each photovoltaic module 120 corresponds to the width direction of the mounting substrate 30.

For convenience of the following description, a plurality of framed photovoltaic modules 100 distributed side by side in the lengthwise direction of the photovoltaic module 120 is defined as one column.

In some exemplary embodiments, in each row of the framed photovoltaic modules 100, the lightning protection wire 50 connects a plurality of the clips 300 of the framed photovoltaic module 100 in series in sequence along the length direction of the photovoltaic module 120, wherein one end of the lightning protection wire 50 is electrically connected to the clip 300 of one framed photovoltaic module 100, and the other end of the lightning protection wire 50 is electrically connected to the clip 300 of the adjacent framed photovoltaic module 100. This setting mode establishes ties in proper order with fixture block 300 in the same row of photovoltaic module 120, can wiring nearby, and the convenient hidden wiring, and saved the cable cost.

It should be noted that, in the present application, the lightning protection wire 50 is electrically connected to the latch 300, which may mean that the lightning protection wire 50 and the latch 300 are electrically contacted with each other and can be electrically conducted through a terminal at an end portion, or that the lightning protection wire 50 and the latch 300 are electrically connected to each other and can be electrically conducted through a terminal at an end portion.

Optionally, the fixture block 300 is provided with a lightning protection wiring clamping groove 340 for clamping the lightning protection wire 50, so that the lightning protection wire 50 can be stably fixed on the fixture block 300, and it is ensured that the wiring terminal at the end of the lightning protection wire 50 can be in electrical contact with the end face of the fixture block 300 better.

Further, based on the above-mentioned serial connection manner, in the present application, the lightning protection wiring clamping grooves 340 are disposed on the clamping blocks 300 located at the two ends of the framed photovoltaic module 100 in the length direction, and the lightning protection wiring clamping groove 340 may not be disposed on the clamping block 300 located at the middle of the framed photovoltaic module 100 in the length direction. Of course, based on consideration of cost and installation convenience, the lightning protection card slot 340 may be disposed on each fixture block 300.

Referring to fig. 4 and fig. 14, as an example, a wiring cavity 312 is formed inside the second connection portion 310, and the lightning protection wiring card slot 340 is located inside the wiring cavity 312. The lightning protection wiring card slot 340 is arranged in the wiring cavity 312, so that the lightning protection wiring card slot 340 has better concealment.

It should be noted that, in the application, the routing cavity 312 may be configured in a closed form, as shown in fig. 4; the trace cavity 312 can also be configured to be non-enclosed, as shown in fig. 14 as an example. Of course, in the case that the routing cavity 312 is not provided in a closed form, the opening position thereof is not limited, and the routing cavity may be provided at the bottom of the second connection portion 310 as shown in fig. 14, or may be provided at a side wall of the second connection portion 310.

Referring to fig. 9, as an example, the lightning protection connector card slot 340 is located at the bottom of the card holder 320. The arrangement mode enables the fixture block 300 to have a simple structure, and the lightning protection wiring card slot 340 can hide the connected lightning protection wire 50 in the mounting groove 33 of the mounting substrate 30, so that the lightning protection wiring card slot has good concealment.

Referring to fig. 10 to 13, in consideration of the fact that the contact surface between the pressing surface 221 and the outer wall of the front frame 1111 is large, in order to more reliably break the contact area between the pressing surface 221 and the outer wall of the front frame 1111, optionally, the pressing surface 221 and the outer wall of the front frame 1111 are both provided with a protruding structure 1112, and the protruding structures 1112 are respectively distributed in the pressing surface 221 and the outer wall of the front frame 1111 in parallel along the width direction of the photovoltaic module 120, so as to present a tooth-like structure.

It is to be understood that the distribution position and shape of the protrusion structures 1112 in the present application are not limited as long as the contact for breaking the insulating film can be generated.

Referring to fig. 10 and 11, as an example, the pressing surface 221 and the protruding structures 1112 arranged on the outer wall of the front frame 1111 are both sharp-angled and protruding.

Referring to fig. 12 and 13, as another example, one of the press-fit surface 221 and the outer wall of the front frame 1111 is provided with a sharp-angled protrusion and the other is provided with a trapezoidal protrusion; for example, the protruding structures 1112 provided on the press-fit surface 221 are pointed protruding spines, and the protruding structures 1112 provided on the outer wall of the front frame 1111 are trapezoidal protruding spines. The convex thorns of the sharp-angle convex thorns are matched with the convex thorns of the trapezoidal convex thorns in a staggered manner.

In the above arrangement mode, two vertex angles of the trapezoidal convex thorns form sharp contact with the side walls of the sharp-angle convex thorns, and the vertex angles of the sharp-angle convex thorns and the transition surfaces between the trapezoidal convex thorns form sharp contact, so that the destruction effect can be better exerted, and the conductivity between the frame 110 and the pressing piece 200 is more reliable.

It is contemplated that in the photovoltaic module lightning protection mounting system 10, the compression element 200 and the latch 300 cooperate to clamp the bezel 110 and the clamping plate 34 therebetween such that there is generally a distance between the compression element 200 and the latch 300.

As an example, the bottom of the first connection portion 210 has a first positioning portion 211, the top of the second connection portion 310 has a second positioning portion 311 for abutting against the first positioning portion 211, and at least one of the first positioning portion 211 and the second positioning portion 311 is provided with a protruding structure 1112 for breaking the insulating film. In this arrangement, the first positioning portion 211 and the second positioning portion 311 can be electrically connected to each other by breaking the insulating film through the protruding structure 1112; the second positioning portion 311 provides a supporting function for the first connecting portion 210 by abutting engagement with the first positioning portion 211, and also makes the engagement between the first connecting portion 210 and the second connecting portion 310 more stable.

In the present application, the electrical contact between the first connection portion 210 and the second connection portion 310 is not limited, and the fastening member 400 may be a threaded structure such as a bolt, for example. In this arrangement, the fastening member 400 is respectively screwed to the first connection portion 210 and the second connection portion 310, and the insulating film is pierced by a friction effect during the screwing, so that the fastening member 400 is used as a conductive medium to electrically contact the first connection portion 210 and the second connection portion 310.

Regarding the manner of providing the positioning portions for electrical contact, in some exemplary embodiments, one of the first positioning portion 211 and the second positioning portion 311 is a concave positioning groove and the other is a convex positioning support rod, for example, the first positioning portion 211 is a concave positioning groove and the second positioning portion 311 is a convex positioning support rod. The free end of the positioning support rod abuts against the groove wall of the positioning groove, and the free end of the positioning support rod is provided with a protruding structure 1112.

In the arrangement mode, the positioning groove and the positioning support rod are convenient to arrange, and the pressing piece 200 and the clamping block 300 are convenient to position during installation; moreover, the arrangement mode ensures that the contact area of the first positioning part 211 and the second positioning part 311 is small, the contact pressure is large, the insulating film at the contact part can be damaged better, and the conductivity between the pressing piece 200 and the fixture block 300 is more reliable.

It is contemplated that the compression element 200, when engaged with the bezel 110 and the latch 300 during installation, is not generally directly aligned and requires angular adjustment. Furthermore, the free end of the positioning support rod is provided with an abutting ball head, and the protruding structure 1112 is arranged on the abutting ball head; the locating slot is an arc-shaped slot matched with the butt ball head. In the arrangement mode, the arrangement mode of the ball head and the arc-shaped groove facilitates the guiding adjustment of the relative position of the ball head and the arc-shaped groove during installation and positioning, so that the installation is more convenient.

In the present application, the shapes of the pressing member 200 and the latch 300 are not limited, and the shapes of the first positioning portion and the second positioning portion are not limited as long as the pressing member 200 and the latch 300 can be in contact engagement with each other to break the insulating film.

As a first example, as shown in fig. 4 and 5 and fig. 7, the pressing member 200 is a flat plate structure as a whole. Wherein, in the direction of height, the size of the body of rod of location bracing piece is greater than the size of bulb for the location bracing piece is whole to have great height, makes the bulb of location bracing piece can better butt arc wall.

As a second example, please refer to fig. 14, which is basically the same as fig. 7, and the main difference is that: the pressing part 220 of the pressing member 200 is provided in an inverted L shape, and the pressing part 220 is higher than the first connecting part 210, so that the distance between the first connecting part 210 and the second connecting part 310 in the assembled state is reduced. In this arrangement, the overall height of the second positioning portion 311 is small, and the size of the rod body is equivalent to that of the ball head in the height direction.

As a third example, please refer to fig. 15, which is basically the same as fig. 13, and the main difference is that: in the photovoltaic roof 1, the holding plate body 34 has a line-shaped structure in which two layers are attached together. Since the height of the clamping plate is reduced, the distance between the first connecting portion 210 and the second connecting portion 310 is reduced, and therefore the pressing portion 220 of the pressing member 200 does not need to be configured in an inverted L shape, and the pressing member 200 is integrally in a flat plate structure.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
