Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module installation. Specifically, it relates to a photovoltaic connection and cooperation module, a frame, a photovoltaic module, and an installation method thereof. Background Art

[0002] Existing photovoltaic modules tend to be installed on the frame. During the installation process, the photovoltaic module is usually placed on the crossbeam, and then a connecting piece corresponding to the crossbeam is installed on the frame of the photovoltaic module, and then the connecting piece is connected to the crossbeam. Currently, there are two common fixing methods for the frame of the photovoltaic module.

[0003] The first installation method is to open a long slot hole on the C surface of the frame. This installation method usually requires multiple bolts to fasten on the crossbeam for each photovoltaic module, and the adjustment distance of the long slot hole is small. Moreover, the crossbeam is prone to deformation during production and installation, resulting in some positions not meeting the installation requirements.

[0004] The second installation method is to use a pressing block to press down on two adjacent frames, and then fasten the pressing block to the crossbeam with bolts. When there are problems such as unreasonable tolerances of the pressing block, deformation of the pressing block during production and transportation, and large installation errors, it is easy to cause the problem that the pressing block does not fit firmly with the frame. When encountering strong wind weather, the photovoltaic module is easy to separate from the pressing block.

[0005] The prior art discloses a photovoltaic support assembly, in which the support is slidably matched with two adjacent frames respectively, and the two adjacent frames are connected into a whole through the support, effectively preventing the photovoltaic module from detaching. However, during installation, the support needs to slide relative to two adjacent frames simultaneously, making the installation difficult.

[0006] The prior art also discloses a support system for photovoltaic modules. Two adjacent photovoltaic modules are connected through an integrated support base. One end of the support base is slidably matched with the photovoltaic module for position adjustment, and the other end of the support base presses down on the adjacent photovoltaic module. The support base is then connected to the crossbeam through fasteners. This support system simplifies the installation operation by installing two photovoltaic modules through an integrated support base; at the same time, during installation, it only needs to slide relative to one side of the photovoltaic module, reducing the installation difficulty. However, since the other end connected by the base is also prone to the problem of poor fitting, the photovoltaic module is easy to separate from the pressing block when encountering strong wind weather. Summary of the Invention

[0007] The purpose of the present application is to provide a photovoltaic connection and cooperation component, a frame, and a photovoltaic component and its installation method: the photovoltaic connection component can conveniently and stably connect and install the frames of two adjacent photovoltaic components, and can effectively adjust the installation position. While effectively avoiding the problem of dust accumulation caused by local water accumulation on the surface of the laminate, the frame ensures that the laminate can be stably adhered.

[0008] The embodiments of the present application are implemented as follows:

[0009] In a first aspect, an embodiment of the present application provides a photovoltaic connection component, including a first photovoltaic connection member and a second photovoltaic connection member. Each photovoltaic connection member has a cooperation portion for cooperating with the frame and a connection portion for fixedly connecting with the crossbeam; along a first preset direction, the cooperation portion slidably cooperates with the frame; along a second preset direction, the cooperation portion and the frame are relatively fixed; the first preset direction is the extending direction of the frame, and the second preset direction is the side-by-side direction of the frame and the photovoltaic connection member.

[0010] Among them, the connection portion of the first photovoltaic connection member is a first connection portion, and the connection portion of the second photovoltaic connection member is a second connection portion. The first connection portion and the second connection portion are configured to be fixedly connected to the crossbeam together by the same fixing member.

[0011] In the above technical solution, the cooperation portion and the frame slidably cooperate in the extending direction of the frame, which is convenient for adjusting the position of the photovoltaic connection member on the frame to better correspond to the crossbeam; at the same time, the cooperation portion and the frame are relatively fixed in the side-by-side direction of the two, so that the photovoltaic connection member and the frame form a whole when cooperating, ensuring the stability of the cooperation between the photovoltaic connection member and the frame.

[0012] The photovoltaic installation component is provided with a first photovoltaic connection member and a second photovoltaic connection member. The two photovoltaic connection members are fixedly connected to the crossbeam together by the same fixing member through the first connection portion and the second connection portion, and the fastening operation is simple. At the same time, the first connection portion and the second connection portion can respectively slidably cooperate with a frame, and the installation operation of the connection portion on the frame is convenient; and the installation of the connection portion on the frame can be carried out before transferring to the crossbeam. After transferring the photovoltaic component to the crossbeam, only the fixing of the first connection portion, the second connection portion and the crossbeam needs to be carried out, which can improve the installation efficiency.

[0013] In some possible implementation schemes, the photovoltaic connection member includes: a first base body and a second base body; the first base body has a first side wall and a second side wall arranged oppositely, and the second base body is connected to the first side wall and extends towards the side away from the second side wall; the cooperation portion is arranged on the first base body, and the connection portion is arranged on the second base body.

[0014] In the above technical solution, the cooperation between the first substrate and the second substrate makes the photovoltaic connector have a generally T-shaped structure or an L-shaped structure. By respectively arranging the connecting part and the mating part on the first substrate and the second substrate, interference between the connecting part and the mating part can be effectively avoided. Among them, the first substrate can extend in the height direction of the frame, which also facilitates the cooperation and installation of the mating part with the frame; the second substrate can extend towards the adjacent photovoltaic connector in the second preset direction, so that the first connecting part and the second connecting part can also be better matched.

[0015] In some possible implementation schemes, the first substrate is also provided with a locking part for cooperating with the frame, so that along the first preset direction, the first substrate can be locked and unlocked with the frame.

[0016] In the above technical solution, it is convenient to slide the photovoltaic connector to the preset position and then lock it during the pre-installation process, so that the photovoltaic connector can be better connected to the frame after pre-installation; at the same time, when the photovoltaic module is transferred to the crossbeam, there is a relatively accurate corresponding relationship between the first connecting part, the second connecting part and the crossbeam, which is convenient for further fastening operations. After the installation on the crossbeam is completed, the locked state is also beneficial to improving the connection stability between the photovoltaic connector and the frame.

[0017] In some possible implementation schemes, the locking part is a screw hole penetrating from the first side wall to the second side wall.

[0018] In the above technical solution, the locking part being a screw hole facilitates locking by tightening the frame with a screw, and the operation is convenient; it also increases the friction force between the connecting part and the frame, and the locking is stable.

[0019] In some possible implementation schemes, the mating part has a first sliding groove and a second sliding groove extending along the first preset direction. The first sliding groove is recessed in the top of the first substrate, and the second sliding groove is recessed in the bottom of the first substrate.

[0020] In the above technical solution, both the top and the bottom of the first substrate are slidably mated with the frame through the sliding grooves, making their relative sliding stable; the side walls of the sliding grooves have a resisting effect on the sliding structure accommodated therein in the second preset direction, and also make the mating part and the frame better maintain relative fixation in the second preset direction.

[0021] In some possible implementation schemes, the first sliding groove is located on one side of the second sliding groove close to the second side wall.

[0022] In the above technical solution, the first sliding groove and the second sliding groove are staggered in the height direction of the first substrate, making the force between the mating part and the frame more balanced, which is beneficial to improving the connection stability.

[0023] In some possible embodiments, the second base body has a third side wall and a fourth side wall that are oppositely arranged; both the third side wall and the fourth side wall are connected to the first side wall and both extend along a first preset direction.

[0024] The third side wall of the first photovoltaic connector has a first limiting portion, and the fourth side wall of the second photovoltaic connector has a second limiting portion; along the first preset direction, the first limiting portion and the second limiting portion are slidably matched.

[0025] In the above technical solution, the first limiting portion and the second limiting portion are slidably matched along the extending direction of the frame. During the process of fastening on the cross beam, when it is necessary to adjust the relative position of the first connecting portion and the second connecting portion, their relative sliding plays a guiding role, and the accurate adjustment of the relative position can be achieved more quickly.

[0026] In some possible embodiments, the first limiting portion includes a first protrusion and a second protrusion, and the first protrusion and the second protrusion are spaced apart along a second preset direction; the second limiting portion includes a third protrusion and a fourth protrusion, and the third protrusion and the fourth protrusion are spaced apart along the second preset direction.

[0027] Wherein, the first protrusion and the second protrusion are slidably abutted between the third protrusion and the fourth protrusion.

[0028] In the above technical solution, the first protrusion and the second protrusion are slidably abutted between the third protrusion and the fourth protrusion, and in the second preset direction, the first limiting portion and the second limiting portion can be relatively fixed: the integrity of the first photovoltaic connector and the second photovoltaic connector is good, and their relative sliding adjustment is more accurate and convenient. The protrusion structure also supports between the second base bodies of the two photovoltaic connectors, and can effectively improve the strength of the second base body.

[0029] In some possible embodiments, the first connecting portion is located between the first protrusion and the second protrusion, and the second connecting portion is located between the third protrusion and the fourth protrusion.

[0030] In the above technical solution, the connecting portion is arranged between the two protrusions. After the connecting portion is connected to the cross beam, the force between the two protrusions is more balanced.

[0031] In some possible embodiments, the first connecting portion is a first through hole that is penetrated, and the second connecting portion is a second through hole that is penetrated; the first through hole and the second through hole are coaxially distributed so as to be fixed to the cross beam together by the same fixing member.

[0032] In the above technical solution, the first connecting portion and the second connecting portion are arranged as through holes, and the first connecting portion and the second connecting portion can be conveniently fixed to the cross beam together by fasteners.

[0033] In a second aspect, an embodiment of the present application provides a photovoltaic cooperation assembly, including at least one set of photovoltaic connection assemblies as provided in the embodiment of the first aspect, a first frame and a second frame. The cooperation part of the first photovoltaic connector is the first cooperation part, and the cooperation part of the second photovoltaic connector is the second cooperation part. The first cooperation part is slidably matched with the first frame, and the second cooperation part is slidably matched with the second frame.

[0034] In the above technical solution, the photovoltaic connection assembly can conveniently and stably connect and install the frames of two adjacent photovoltaic modules, and can effectively adjust the installation position.

[0035] In some possible implementation schemes, the frame has a cooperation cavity, which is formed by the B surface of the frame recessing towards the side where the corner code cavity of the frame is located; the cooperation cavity is used to match with the cooperation part, so that along the first preset direction, the cooperation part slides and cooperates with the frame, and along the second preset direction, the cooperation part and the frame are relatively fixed.

[0036] In the above technical solution, the cooperation cavity is formed by the B surface of the frame recessing towards the side where the corner code cavity of the frame is located, and the cooperation part slides in the cooperation cavity inside the frame, and the sliding connection between the cooperation part and the frame is relatively stable.

[0037] In some possible implementation schemes, sliding flanges are convexly provided on both the top inner wall and the bottom inner wall of the cooperation cavity, and the sliding flanges extend along the first preset direction; along the first preset direction, the cooperation part is slidably matched with the sliding flanges.

[0038] In the above technical solution, both the top and the bottom of the cooperation cavity are slidably matched with the cooperation part through the sliding flanges, making the relative sliding between the two stable.

[0039] In some possible implementation schemes, the frame does not have an A surface; a convex block is provided in the installation cavity of the frame; the convex block is provided at one end of the bottom wall of the installation cavity close to the B surface of the frame and is connected to the B surface of the frame; along the depth direction of the installation cavity, the height of the convex block is less than the depth of the installation cavity.

[0040] In the above technical solution, the setting of the convex block can be used as an indication part. When applying an adhesive to the bottom wall of the installation cavity, it is convenient to apply an adhesive with an appropriate thickness with reference to the height of the convex block, ensuring that the adhesive has a good bonding effect on the laminate.

[0041] In a third aspect, an embodiment of the present application provides a photovoltaic module system, including a laminate and a photovoltaic cooperation assembly as provided in the embodiment of the second aspect; the laminate is installed in the installation cavity of the frame.

[0042] In the above technical solution, the photovoltaic connection assembly can conveniently and stably connect and install the frames of two adjacent photovoltaic modules, and can effectively adjust the installation position.

[0043] In some possible embodiments, the frame does not have an A side, a first adhesive is filled between the bottom wall of the laminate and the mounting cavity, and the upper surface of the laminate is not lower than the top of the B side of the frame.

[0044] In the above technical solution, since the frame does not have an A side and the upper surface of the laminate is not lower than the top of the B side of the frame, it can effectively avoid the problem of dust accumulation caused by local water accumulation on the surface of the laminate.

[0045] In some possible embodiments, a second adhesive is filled between the laminate and the B side of the frame.

[0046] In the above technical solution, the second adhesive can achieve the sealing between the edge of the laminate and the B side of the frame, and at the same time can strengthen the bonding effect between the laminate and the frame.

[0047] In some possible embodiments, the upper surface of the laminate is higher than the top of the B side of the frame, and the second adhesive has an inclined plane, which is connected between the upper surface of the laminate and the top of the B side of the frame.

[0048] In the above technical solution, the inclined plane gradually slopes downward from the upper surface of the laminate towards the top of the B side of the frame, making the appearance of the photovoltaic module beautiful, and at the same time facilitating the water to slide down along the inclined plane to effectively avoid local water accumulation at the edge of the surface of the laminate.

[0049] In some possible embodiments, a convex block is provided in the mounting cavity; the convex block is provided at one end of the bottom wall of the mounting cavity close to the B side of the frame and is connected to the B side of the frame; along the depth direction of the mounting cavity, the height of the convex block is less than the depth of the mounting cavity, and the thickness of the first adhesive is the same as the height of the convex block.

[0050] In the above technical solution, the setting of the convex block can be used as an indication part. When applying the adhesive to the bottom wall of the mounting cavity, it is convenient to apply the adhesive with a suitable thickness by referring to the height of the convex block. With a suitable thickness of the adhesive, it can ensure a good bonding effect of the adhesive on the laminate.

[0051] Fourthly, an installation method of a photovoltaic module system provided by an embodiment of the present application is carried out by using the photovoltaic matching module provided by the embodiment of the second aspect. The installation method includes:

[0052] Slidably matching the first matching part with the first frame connected with the laminate, and slidably matching the second matching part with the second frame connected with the laminate.

[0053] Transfer the frame connected with the first matching part and the frame connected with the second matching part to the cross beam, so that both the first connecting part and the second connecting part correspond to the cross beam, and the first connecting part and the second connecting part correspond to each other.

[0054] The first connecting portion and the second connecting portion are fixed to the cross beam by the same fixing member.

[0055] In the above technical solution, a photovoltaic cooperation component is adopted, which has a photovoltaic connection component. During installation, the first cooperation portion and the second cooperation portion are respectively in sliding cooperation with a frame. The connection portion is convenient for installation operation on the frame. The connection between the photovoltaic connecting member and the frame is pre-installed before being transferred to the cross beam. After transferring the photovoltaic module to the cross beam, only the fixing of the first connecting portion and the second connecting portion to the cross beam is required, which can improve the installation efficiency. At the same time, when fastening on the cross beam, the cooperation portion and the frame are in sliding cooperation in the extending direction of the frame, which can effectively adjust the installation position; the first connecting portion and the second connecting portion are fixed to the cross beam by the same fixing member together, and the fastening operation is also simple.

[0056] Further, an embodiment of the present application provides a frame that does not have an A surface, and a convex block is provided in the installation cavity of the frame; the convex block is provided at one end of the bottom wall of the installation cavity close to the B surface of the frame and is connected to the B surface of the frame; along the depth direction of the installation cavity, the height of the convex block is less than the depth of the installation cavity.

[0057] In the above technical solution, the setting of the convex block can be used as an indication part. When applying the adhesive on the bottom wall of the installation cavity, it is convenient to apply the adhesive with a suitable thickness with reference to the height of the convex block, ensuring that the adhesive has a good bonding effect on the laminate.

[0058] In a sixth aspect, an embodiment of the present application provides a photovoltaic module, including a laminate and the frame provided in the fifth aspect embodiment; a first adhesive is filled between the laminate and the bottom wall of the installation cavity, and the upper surface of the laminate is not lower than the top end of the B surface of the frame.

[0059] In some possible implementation manners, along the depth direction of the installation cavity, the thickness of the first adhesive is the same as the height of the convex block.

[0060] In the above technical solution, the frame does not have an A surface and the upper surface of the laminate is not lower than the top end of the B surface of the frame, which can effectively avoid the problem of dust accumulation caused by local water accumulation on the surface of the laminate. The setting of the convex block also facilitates applying the first adhesive with a suitable thickness, ensuring the bonding effect of the first adhesive.

[0062] In the above technical solution, the second adhesive can achieve the sealing between the edge of the laminate and the B surface of the frame, and at the same time can strengthen the bonding effect between the laminate and the frame.

[0063] In some possible embodiments, the upper surface of the laminate is higher than the top end of the B surface of the frame; the second adhesive has an inclined plane that is connected between the upper surface of the laminate and the top end of the B surface of the frame.

[0081] Please refer to Figure 1 , Figure 1 which shows an existing frame with side A 100, which has side A 110, side B 120, and an installation cavity 130. In the embodiments of the present application, unless otherwise specified, the structure of the frame can be referred to Figure 1 the frame with side A 100 shown.

[0082] Embodiment 1

[0083] Please refer to Figures 2 to 4 , this embodiment provides a photovoltaic connection component 202, including a first photovoltaic connector 210 and a second photovoltaic connector 210. When there is no special indication, the structures of the first photovoltaic component and the second photovoltaic component can be understood to be the same.

[0084] Each photovoltaic connector 210 has a mating portion 213 for mating with the frame and a connecting portion 214 for fixedly connecting with the crossbeam. Define a first preset direction and a second preset direction, where the first preset direction is the extending direction of the frame, that is, the a direction as shown in Figure 3 ; the second preset direction is the side-by-side direction of the frame and the photovoltaic connector 210, that is, the b direction as shown in Figure 3 .

[0085] In this embodiment, along the first preset direction, the mating portion 213 is in sliding fit with the frame, and this setting method facilitates adjusting the position of the photovoltaic connector 210 on the frame to better correspond to the crossbeam. Along the second preset direction, the mating portion 213 and the frame are relatively fixed, so that the photovoltaic connector 210 and the frame form a whole when mating, ensuring the stability of the mating between the photovoltaic connector 210 and the frame.

[0086] It can be understood that in the embodiments of the application, the above-mentioned cooperation mode between the cooperation part 213 and the frame is not limited. For example, the cooperation part 213 can be set in the form of a limiting block. The limiting block is, for example, a T-shaped slider. In this case, a frame provided with a corresponding limiting groove is adopted; for example, the cooperation part 213 can also be set in the form of a limiting groove. The limiting groove is, for example, a T-shaped sliding groove. In this case, a frame provided with a corresponding limiting block is adopted.

[0087] In this embodiment, the connecting part 214 of the first photovoltaic connecting piece 210 is the first connecting part 214, and the connecting part 214 of the second photovoltaic connecting piece 210 is the second connecting part 214. The first connecting part 214 and the second connecting part 214 are configured to be fixed to the cross beam together by the same fixing piece 218. Exemplarily, the photovoltaic connection assembly 202 further includes the fixing piece 218. The first connecting part 214 and the second connecting part 214 are fixed to the cross beam by the same fixing piece 218, and the fastening operation is simple. At the same time, the first connecting part 214 and the second connecting part 214 can be respectively in sliding cooperation with a frame. The installation of the connecting part 214 on the frame is convenient; and the installation of the connecting part 214 on the frame can be carried out before transferring to the cross beam. Through the pre-installation operation of the connecting part 214 on the frame, after transferring the photovoltaic module to the cross beam, only the fixing of the first connecting part 214 and the second connecting part 214 to the cross beam needs to be carried out, which can improve the installation efficiency.

[0088] It should be noted that in the embodiments of the present application, the manner in which the first connecting part 214 and the second connecting part 214 are fixed to the cross beam together by the same fixing piece 218 at least includes the following manners: In the first manner, the first connecting part 214 is connected to the fixing piece 218, the second connecting part 214 is connected to the fixing piece 218, and then the fixing piece 218 is connected to the cross beam; In the second manner, the first connecting part 214 and the second connecting part 214 are detachably connected. The detachable connection manner is, for example, a fastening connection or a snap connection. One of the first connecting part 214 and the second connecting part 214 is connected to the fixing piece 218, and then the fixing piece 218 is connected to the cross beam.

[0089] Exemplarily, the first connecting part 214 is a first through hole formed therethrough, and the second connecting part 214 is a second through hole formed therethrough. The fixing piece 218 is preferably an installation bolt; the first through hole and the second through hole are coaxially distributed so as to be fixed to the cross beam together by the same fixing piece 218. By setting the first connecting part 214 and the second connecting part 214 as through holes, the first connecting part 214 and the second connecting part 214 can be conveniently fixed to the cross beam together by fasteners.

[0090] Please refer to Figure 4, in some possible embodiments, the photovoltaic connector 210 includes a first base body 211 and a second base body 212. The first base body 211 has a first side wall 2111 and a second side wall 2112 that are oppositely arranged. The second base body 212 is connected to the first side wall 2111 and extends away from the second side wall 2112, such that the photovoltaic connector has a substantially T-shaped structure or a substantially L-shaped structure. Exemplarily, the first base body 211 and the second base body 212 are perpendicular.

[0091] The mating portion 213 is provided on the first base body 211, and the connecting portion 214 is provided on the second base body 212, which can effectively prevent interference between the connecting portion 214 and the mating portion 213. Among them, the first base body 211 can extend in the height direction of the frame, which also facilitates the mating and installation of the mating portion 213 with the B surface 120 of the frame; the second base body 212 can extend toward the adjacent photovoltaic connector 210 in the second preset direction, such that the first connecting portion 214 and the second connecting portion 214 can also be better matched.

[0092] Define the third preset direction as the height direction of the first base body 211, such as Figure 4 the c direction shown. Exemplarily, the mating portion 213 has a first chute 2131 and a second chute 2132 that extend along the first preset direction. The first chute 2131 is recessed in the top of the first base body 211 in the third preset direction, and the second chute 2132 is recessed in the bottom of the first base body 211 in the third preset direction. Both the top and the bottom of the first base body 211 are slidably mated with the frame through the chutes, making their relative sliding stable; it can be understood that the frame has a sliding structure for mating with the chutes of the mating portion 213, and the side walls of the chutes of the mating portion 213 have a holding effect on the sliding structure accommodated therein in the second preset direction, such that the mating portion 213 and the frame can be better relatively fixed in the second preset direction.

[0093] Further, in the third preset direction, the first chute 2131 and the first chute 2131 are staggered. Optionally, the first chute 2131 is located on the side of the second chute 2132 close to the second side wall 2112. The first chute 2131 and the second chute 2132 are staggered in the height direction of the first base body 211, making the force between the mating portion 213 and the frame more balanced, which is beneficial to improving the connection stability.

[0094] Please continue to refer to Figure 3 and Figure 4, in some exemplary embodiments, the first base body 211 is further provided with a locking portion 215 for cooperating with the frame, so that the first base body 211 can be locked and unlocked with the frame along a first preset direction. During the pre-installation process, after sliding the photovoltaic connector 210 to a preset position, it is locked, so that the photovoltaic connector 210 can be better connected to the frame after pre-installation; at the same time, since the photovoltaic connector 210 is fixed at a relatively accurate preset position, when the photovoltaic module is transferred to the cross beam, there is a relatively accurate corresponding relationship between the first connecting portion 214, the second connecting portion 214 and the cross beam, which is convenient for further fastening operations. After the installation on the cross beam is completed, the locked state is also beneficial to improving the connection stability between the photovoltaic connector 210 and the frame.

[0095] Optionally, the locking portion 215 is a screw hole penetrating from the first side wall 2111 to the second side wall 2112. Further, each photovoltaic connector 210 further has a fastening screw for cooperating with the screw hole; the fastening screw is, for example, an internal hexagonal flat-end fastening screw, which is convenient to drive the fastening screw to rotate in the screw hole through a hexagonal wrench to achieve locking and unlocking.

[0096] The locking portion 215 being a screw hole facilitates locking by screwing the screw against the frame, and the operation is convenient; while the screw tightens the frame, the friction between the connecting portion 214 and the frame is also increased, and the locking is stable. Moreover, it is convenient to accurately lock the mating portion 213 at any preset position.

[0097] It can be understood that the setting manner of the locking portion 215 is not limited. In other embodiments, for example, it can also be provided with a pin through hole in the first base body 211, and a plurality of pin counterbores corresponding to the pin through hole are recessed in the frame correspondingly, and the locking and unlocking are realized by controlling the state of the pin cooperation.

[0098] Please continue to refer to Figure 4 , the second base body 212 has a third side wall 2121 and a fourth side wall 2122 which are oppositely arranged; both the third side wall 2121 and the fourth side wall 2122 are connected to the first side wall 2111 and both extend along the first preset direction, and the third side wall 2121 and the fourth side wall 2122 are relatively spaced apart in a third preset direction. Optionally, both the third side wall 2121 and the fourth side wall 2122 are perpendicular to the third preset direction.

[0099] Exemplarily, when the first photovoltaic connector 210 and the second photovoltaic connector 210 are respectively connected to two adjacent frames, the second base bodies 212 of the first photovoltaic connector 210 and the second photovoltaic connector 210 are relatively spaced apart in the third preset direction. In the embodiment where the connecting portion 214 is a through hole opened therethrough, the through hole is opened from the third side wall 2121 to the fourth side wall 2122.

[0100] The third side wall 2121 of the first photovoltaic connector 210 is the side wall close to the second base body 212 of the second photovoltaic connector 210, and the fourth side wall 2122 of the second photovoltaic connector 210 is the side wall close to the second base body 212 of the first photovoltaic connector 210.

[0101] Optionally, the third side wall 2121 of the first photovoltaic connector 210 has a first limiting portion, and the fourth side wall 2122 of the second photovoltaic connector 210 has a second limiting portion. Along the first preset direction, the first limiting portion and the second limiting portion are slidably engaged. During the fastening process on the cross beam, when it is necessary to adjust the relative position of the first connecting portion 214 and the second connecting portion 214, their relative sliding plays a guiding role, and the accurate adjustment of the relative position can be achieved more quickly.

[0102] Exemplarily, the first limiting portion includes a first protrusion 2161 and a second protrusion 2162, and the first protrusion 2161 and the second protrusion 2162 are spaced apart along the second preset direction; the second limiting portion includes a third protrusion 2171 and a fourth protrusion 2172, and the third protrusion 2171 and the fourth protrusion 2172 are spaced apart along the second preset direction. The protrusion structure is supported between the second base bodies 212 of the two photovoltaic connectors 210, which can effectively improve the strength of the second base body 212.

[0103] Wherein, the first protrusion 2161 and the second protrusion 2162 are slidably abutted between the third protrusion 2171 and the fourth protrusion 2172. In the second preset direction, the first limiting portion and the second limiting portion can be relatively fixed. In this setting mode, the integrity of the first photovoltaic connector 210 and the second photovoltaic connector 210 is good, and the relative sliding adjustment between the two is more accurate and convenient. It should be noted that in other embodiments, the first limiting portion and the second limiting portion can also be slidably engaged by means of a chute and a slider, for example.

[0104] Furthermore, the first connecting portion 214 is located between the first protrusion 2161 and the second protrusion 2162, and the second connecting portion 214 is located between the third protrusion 2171 and the fourth protrusion 2172. After the connecting portion 214 is connected to the cross beam, the force between the two protrusions is more balanced.

[0105] Embodiment 2

[0106] Please refer to Figure 5, this embodiment provides a photovoltaic matching component 201, which includes at least one set of photovoltaic connection components 202 provided in Embodiment 1, a first frame and a second frame. The mating portion 213 of the first photovoltaic connector 210 is the first mating portion 213, and the mating portion 213 of the second photovoltaic connector 210 is the second mating portion 213. The first mating portion 213 is slidably mated with the first frame, and the second mating portion 213 is slidably mated with the second frame. It can be understood that the structure of the frame needs to be correspondingly adjusted according to the structure of the mating portion 213, and this frame is a sliding frame 220.

[0107] Please refer to Figure 6 , optionally, the sliding frame 220 has a mating cavity 221 for matching with the mating portion 213. Exemplarily, the mating cavity 221 is formed by recessing from the B surface 120 of the frame towards the side where the corner code cavity of the frame is located. Along the first preset direction, the mating portion 213 slides in cooperation with the frame; along the second preset direction, the mating portion 213 and the frame are relatively fixed. The frame is recessed with the mating cavity 221 for sliding cooperation with the mating portion 213, and the mating portion 213 slides in the mating cavity 221 inside the frame, and the sliding connection between the mating portion 213 and the frame is relatively stable.

[0108] Furthermore, sliding flanges 222 are convexly provided on both the top inner wall and the bottom inner wall of the mating cavity 221, and the sliding flanges 222 extend along the first preset direction; along the first preset direction, the mating portion 213 is slidably mated with the sliding flanges 222. Exemplarily, the photovoltaic connector 210 has a structure in which a first chute 2131 is recessed at the top of the first base 211 and a second chute 2132 is recessed at the bottom of the first base 211. The first chute 2131 is slidably mated with the sliding flanges 222 on the top inner wall of the mating cavity 221, and the second chute 2132 is slidably mated with the sliding flanges 222 on the bottom inner wall of the mating cavity 221, making the relative sliding between the mating cavity 221 and the mating portion 213 stable.

[0109] It should be noted that in the embodiments of the present application, the manner in which the mating portion 213 and the frame are relatively fixed along the second preset direction is not limited to the above form of setting flanges. In other implementation manners, for example, the mating cavity 221 can also be set as a C-shaped limiting groove or a trapezoidal limiting groove.

[0110] It can be understood that for the photovoltaic matching component 201 provided in the embodiments of the present application, the frame is mated with the photovoltaic connector 210 through the side where the B surface 120 is located, and the side where the A surface 110 of the frame is located can be unobstructed. This frame can be a frame with an A surface 110 or a frame without an A surface 110.

[0111] Exemplarily, the frame does not have the A surface 110, which can effectively prevent the A surface 110 from protruding out of the surface of the laminate 230, so as to avoid the problem of dust accumulation caused by local water accumulation on the surface of the laminate 230.

[0112] When laminating the laminate 230 with a frame without the A surface 110, an adhesive is usually coated on the bottom wall of the installation cavity 130 to bond the laminate 230. When the adhesive has a suitable thickness, it has a good pasting effect on the laminate 230.

[0113] Furthermore, a convex block 223 is provided in the installation cavity 130 of the frame; the convex block 223 is provided at one end of the bottom wall of the installation cavity 130 close to the B surface 120 of the frame and is connected to the B surface 120 of the frame. Along the depth direction of the installation cavity 130, which is the third preset direction, the height of the convex block 223 is less than the depth of the installation cavity 130. The setting of the convex block 223 can be used as an indication part. When coating the adhesive on the bottom wall of the installation cavity 130, it is convenient to coat the adhesive with a suitable thickness with reference to the height of the convex block 223, so as to ensure that the adhesive has a good bonding effect on the laminate 230.

[0114] Embodiment 3

[0115] Please refer to Figure 7 , a photovoltaic module system 200, including a laminate 230 and the photovoltaic cooperation component 201 provided in Embodiment 2; the laminate 230 is installed in the installation cavity 130 of the frame.

[0116] Exemplarily, the frame does not have the A surface 110. A first adhesive 240 is filled between the laminate 230 and the bottom wall of the installation cavity 130. The first adhesive 240 is exemplarily a structural adhesive, and the upper surface of the laminate 230 is not lower than the top end of the B surface 120 of the frame, effectively avoiding the problem of dust accumulation caused by local water accumulation on the surface of the laminate 230.

[0117] Furthermore, the frame without the A surface 110 has a structure with a convex block 223 at the bottom of the installation cavity 130. Along the depth direction of the installation cavity 130, the thickness of the first adhesive 240 is the same as the height of the convex block 223. The adhesive has a suitable thickness, ensuring that the adhesive has a good bonding effect on the laminate 230.

[0118] In some possible implementation schemes, a second adhesive 250 is filled between the laminate 230 and the B surface 120 of the frame. The second adhesive 250 is used to seal the end of the laminate 230. The second adhesive 250 is exemplarily a sealant, such as a silicone sealant. The second adhesive 250 can achieve the seal between the edge of the laminate 230 and the B surface 120 of the frame, and at the same time can strengthen the bonding effect between the laminate 230 and the frame.

[0119] Further, in an embodiment filled with the second adhesive 250, the upper surface of the laminate 230 is higher than the top end of the B surface 120 of the frame. The second adhesive 250 has an inclined plane, which is connected between the upper surface of the laminate 230 and the top end of the B surface 120 of the frame. The inclined plane gradually slopes downward from the upper surface of the laminate 230 towards the top end of the B surface 120 of the frame, making the appearance of the photovoltaic module beautiful. At the same time, it is beneficial for water to slide down along the inclined plane, effectively avoiding local water accumulation at the edge of the surface of the laminate 230.

[0120] The photovoltaic fitting assembly 201 provided by the embodiment of the present application is used for installing the photovoltaic module system 200. The installation method of the photovoltaic module system 200 includes: slidingly mating the first fitting portion 213 with the first frame connected to the laminate 230, and slidingly mating the second fitting portion 213 with the second frame connected to the laminate 230. Transfer the frame connected with the first fitting portion 213 and the frame connected with the second fitting portion 213 to the crossbeam, so that both the first connecting portion 214 and the second connecting portion 214 correspond to the crossbeam, and the first connecting portion 214 and the second connecting portion 214 correspond to each other. Fix the first connecting portion 214 and the second connecting portion 214 to the crossbeam by using the same fixing member 218.

[0121] In this connection method, the first fitting portion 213 and the second fitting portion 213 are respectively slidingly mated with a frame, and the installation operation of the connecting portion 214 on the frame is convenient. The connection between the photovoltaic connector 210 and the frame is a pre-installation before transferring to the crossbeam. After transferring the photovoltaic module to the crossbeam, only the fixing of the first connecting portion 214 and the second connecting portion 214 to the crossbeam is required, which can improve the installation efficiency. At the same time, when tightening on the crossbeam, the fitting portion 213 and the frame are slidingly mated in the extending direction of the frame, which can effectively adjust the installation position; the first connecting portion 214 and the second connecting portion 214 are fixed to the crossbeam by the same fixing member 218 together, and the tightening operation is also simple.

[0122] Embodiment 4

[0123] Please refer to Figure 8 , this embodiment provides a frame, which is a frame without an A surface 300. In this embodiment, the difference between it and the existing frame with an A surface 100 is that the frame without an A surface 300 does not have an A surface 110. At the same time, a convex block 223 is provided in the installation cavity 130 of the frame. The convex block 223 is arranged at one end of the bottom wall of the installation cavity 130 close to the B surface 120 of the frame and is connected to the B surface 120 of the frame; along the depth direction of the installation cavity 130, the height of the convex block 223 is less than the depth of the installation cavity 130.

[0124] The provision of the bump 223 can serve as an indication part. When applying the adhesive to the bottom wall of the installation cavity 130, it is convenient to apply the adhesive with an appropriate thickness by referring to the height of the bump 223, ensuring that the adhesive has a good bonding effect on the laminate 230.

[0125] It can be understood that for the borderless A-side 300 provided in this embodiment, the remaining structures can be the same as those of the existing bordered A-side 100, or the same as the border in Embodiment 2.

For the connection method between the laminate 230 and the border, specifically, reference can be made to the connection method using the first adhesive and the further connection method using the second adhesive in Embodiment 3, which will not be elaborated here.

[0128] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
