Building Integrated Photovoltaic (abbreviated as BIPV) is a new concept of applying solar power generation, which simply means that a solar Photovoltaic power generation matrix is installed on the outer surface of an enclosure structure of a Building to provide power. Enclosures herein include, but are not limited to, sound barriers, building enclosures, glass siding, and the like.

By taking the photovoltaic module applied to the sound barrier as an example, the technical problems of the existing photovoltaic module are explained.

The frame included in the existing photovoltaic module generally includes a long frame and a short frame, and the long/short frames are connected end to enclose a clamping space for clamping a laminated piece (the laminated piece includes a glass cover plate, a first packaging adhesive film layer, a battery piece layer, a second packaging adhesive film layer and a back plate which are sequentially laminated from top to bottom). In order to realize the end-to-end connection of the long/short frame, the end of the long/short frame far away from the laminated part is generally provided with a cavity, the inner wall of the cavity is provided with a plurality of pressure points which are distributed at intervals, and correspondingly, pressure point grooves are formed between the adjacent pressure points. On the basis, the prior art needs to provide an angle core, which structurally generally comprises two wing plates perpendicular to each other, and pressure points are distributed at intervals on the surfaces of the wing plates, which are in contact with the inner wall of the cavity. In the practical application process, special assembling equipment can be adopted to insert the two wing plates into the cavities of the long/short frames respectively, and at the moment, the pressure points on the wing plates can be just clamped into the pressure point grooves on the inner walls of the cavities. Based on this, the fastening connection of the long/short rims can be realized with the angle cores. When the photovoltaic module needs to remove the long/short frame from the laminated part due to failure, a violent removing mode is generally used, and at the moment, the pressure point connection part is damaged due to violence, so that the removed long/short frame cannot be reused, and the problem of wasting the long/short frame exists. Furthermore, the manner of violent dismantling entails a considerably increased risk of damage to the laminate.

From the above application process, in practical application, it is necessary to insert the two wing plates of the angle core into the cavities of the long/short frames respectively by using special assembly equipment, and then fasten the angle core in the cavity of the long/short frame to realize the fastening connection of the long/short frames. That is, the existing connection of the long/short bezel is not only complicated in steps but also requires a dedicated assembly apparatus. In this case, not only the input cost of the dedicated assembly equipment is increased, but also a plurality of operators are required to participate, and the skill requirement for the operators is high. Accordingly, there are problems in that the equipment and labor costs are high and the assembling efficiency is low. In addition, the use of a violent dismantling method can affect the secondary use of the long/end frame, lead to the waste of materials of the long/end frame and improve the probability of the damage of the laminated part.

In addition, the long/short frames are connected by clamping the pressure points and the pressure point grooves, and the problem of looseness easily occurs between the pressure points and the pressure point grooves in the carrying process after assembly is completed. In addition, when the photovoltaic module after the completion of the assembly receives impact force, under the effect of bending moment and/or pressure, the pressure point and the pressure point groove which are originally clamped together are easy to loosen. Based on this, the long/short bezel may be caused to detach from the edge of the laminate, thereby exacerbating damage of the photovoltaic module.

At present, a photovoltaic module provided by the prior art is generally a rectangular photovoltaic module, and at this time, a clamping space formed by enclosing of a long frame and a short frame is a rectangular clamping space. Based on this, in order to ensure that the clamping space enclosed by the long/short frames is a rectangular clamping space, the end portions of the long/short frames need to be beveled at 45 degrees, so that the end portions of the long/short frames form an included angle of 90 degrees after being butted. However, the utility model discloses the people discover, in practical application, because 45 bevels handle and have process error, lead to the contained angle that long/short frame formed after the butt joint not to equal to 90. That is, after the long/short frames are butted, a large gap exists at the butted position. The existence of gaps can make the final formed photovoltaic module not reach the requirement of shipment and can affect the aesthetic appearance of the photovoltaic module. More importantly, the existence of the gap can reduce the connection strength of the long/short frame. That is to say, when photovoltaic module received external impact, the frame was damaged in gap department easily to lead to photovoltaic module's repair rate and loss higher.

According to the photovoltaic module provided by the prior art, after the edge of the laminated part and the frame are clamped, in order to ensure the sealing performance and the connection tightness of the joint, sealant needs to be injected into the joint. At this time, the sealant overflows, and the overflowing sealant needs to be cleaned in order not to affect the appearance of the photovoltaic module. However, cleaning the sealant requires waiting for the spilled sealant to air dry before it can be performed. Therefore, the assembly time of the photovoltaic module is longer, and the assembly efficiency is affected.

When the existing photovoltaic modules are applied to the sound barrier, the problem of sound leakage can be caused because no buffer or other connection treatment exists between the photovoltaic modules. Moreover, no effective positioning measure exists among the photovoltaic modules, so that the finally formed sound barrier has the problem of front and back unevenness, and the appearance of the sound barrier is influenced. Of course, when the existing photovoltaic module is applied to other building facades, the problem of influencing the appearance can also exist.

The existing photovoltaic module applied to the sound barrier comprises a junction box, outgoing lines and the like which are exposed outside, and the junction box and cables are easy to lose efficacy in an outdoor severe environment.

In view of the technical problems in the prior art, in a first aspect, the embodiments of the present invention provide a frame, and it should be understood that the frame provided in the embodiments of the present invention may be applied to not only building-integrated photovoltaic, but also conventional power generation systems.

Referring to fig. 1 to 3, the bezel provided by the embodiment of the present invention includes a first bezel 10 and a second bezel 20, and the first bezel 10 and the second bezel 20 are vertically butted end to end and mechanically connected to enclose a clamping space for clamping the laminate.

It should be understood that when the laminate provided by the prior art is a rectangular laminate, the first frame 10 may be a long frame and the second frame 20 may be a short frame. Alternatively, the first frame 10 is a short frame and the second frame 20 is a long frame. The following description takes the first frame 10 as a long frame and the second frame 20 as a short frame as an example, but the following examples are only for clarity and are not intended to be limiting.

Referring to fig. 1 and 2, in practical applications, a 90 ° butt joint angle is formed after the first frame 10 (long frame) and the second frame 20 (short frame) are vertically butted end to end. Therefore, the first frame 10 and the second frame 20 do not need to be beveled at 45 ° from the head to the tail. At this time, the problem that a large gap exists at the butt joint due to the error of the beveling process can be effectively avoided. Based on this, under the condition of optimizing photovoltaic module aesthetic measure and joint strength, can reduce photovoltaic module's rate of reprocessing and loss. And because the first frame 10 and the second frame 20 are vertically butted, the butting process has higher fault tolerance rate relative to the butting process after 45-degree beveling processing, so that the requirement on the skill of an operator is not high.

Referring to fig. 1 and 2, after the first frame 10 and the second frame 20 are vertically butted end to end, the first frame 10 and the second frame 20 are fastened together by mechanical connection to enclose a clamping space for clamping the laminate. Compared with the press point connection mode in the prior art, the mechanical connection mode can improve the connection strength of the first frame 10 and the second frame 20, and on the basis, the connection stability and the connection strength of the first frame 10 and the second frame 20 can be effectively improved. Under the condition that the connection strength is effectively improved, after the photovoltaic module is subjected to impact force, the photovoltaic module can resist larger bending moment and/or shearing force and/or pressure, and the risk of falling off between the first frame 10 and the second frame 20 is reduced. Furthermore, since the mechanical connection does not require separate installation equipment, the cost of the installation equipment can be reduced, the skill of the operator is not required, and the installation efficiency can be improved. In addition, because special assembling equipment is not needed, the requirement on an installation site or a construction site (for example, the method can be suitable for any construction site such as a factory or a field) is not high, and the installation adaptability can be effectively improved.

Referring to fig. 1 and 2, the first frame 10 and the second frame 20 are fastened and connected together in a mechanical connection manner, and when reverse disassembly is required, the connecting members are directly disassembled without adopting a violent disassembling manner in the prior art, so that the frames (including the first frame 10 and the second frame 20) can be quickly replaced in a construction site. Due to the adoption of a non-violent dismantling mode, the dismantled frame cannot be damaged, namely, the secondary use of the frame cannot be influenced. Furthermore, the probability of damaging the laminate during non-violent dismantling is greatly reduced.

Referring to fig. 1 and 2, it should be further explained that the above-mentioned mechanical connection refers to a connection manner of transmitting the force of the first frame 10 (or the force of the second frame 20) to the second frame 20 (or the first frame 10) through a mechanical engagement action of the connecting member with the first frame 10 and the second frame 20, or a pressure bearing action at the connection position of the first frame 10 and the second frame 20. The mechanical connection mainly comprises a threaded connection and a compression sleeve connection. The mechanical connection of the first frame 10 and the second frame 20 will be described in detail below by way of example only, and it should be understood that the following example is illustrative only and not limiting.

Referring to fig. 1 and 2, as a possible implementation manner, a plurality of first mounting holes are formed at a contact portion between the first frame 10 and the second frame 20, and a plurality of second mounting holes corresponding to the first mounting holes are formed at a contact portion between the second frame 20 and the first frame 10. The frame further comprises a plurality of fasteners, each of which is rotatably coupled in the corresponding first and second mounting holes for fastening the first and second frames 10 and 20.

Referring to fig. 1 and 2, a first mounting hole and a second mounting hole, which correspond to each other, and a fastening member simultaneously screwed into the first mounting hole and the second mounting hole may be defined as a mounting unit. In the embodiment of the present invention, the first frame 10 and the second frame 20 are fastened and connected by using the plurality of mounting units, so that the connection strength between the first frame 10 and the second frame 20 can be improved, and the connection stability between the first frame 10 and the second frame 20 can be further improved. Moreover, in the actual assembly process, after the first frame 10 and the second frame 20 are butted end to end, the first mounting hole and the second mounting hole belonging to the same mounting unit are in one-to-one correspondence in space, and at this time, the fastening piece is directly screwed in and further screwed in the first mounting hole and the second mounting hole, so that the fastening connection of the first frame 10 and the second frame 20 can be realized. Therefore, the first frame 10 and the second frame 20 can be fastened and connected simply without configuring other special assembling equipment in the assembling process, and the assembling process is simple and the connecting stability is high.

Referring to fig. 1, 2, 4 and 7, as an example, the first bezel 10 may include a first chucking plate 101 (which may be used to chuck a cover plate of a laminate) having a cavity, a second chucking plate 102 (which may be used to chuck a back plate of a laminate) having a cavity, a first package plate 103 connecting the first and second chucking plates 101 and 102, and a leg plate 104 disposed at an end of the second chucking plate opposite to the first package plate 103. A first clamping groove 105 for clamping the laminate is enclosed by the first clamping plate 101, the second clamping plate 102, the first package plate 103 and the foot plate 104. It is to be understood that the integrated first bezel 10 may be formed by the first card-mounting plate 101, the second card-mounting plate 102, the first package plate 103, and the foot plate 104. The second frame 20 may include a third clamping plate 201 (which may be used to clamp a cover plate of a laminate), a fourth clamping plate 202 (which may be used to clamp a back plate of a laminate), a second packaging plate 203 connecting the third clamping plate 201 and the fourth clamping plate 202, and ribs 204 respectively disposed on inner walls of the cavities of the third clamping plate 201 and the fourth clamping plate 202 along a length direction of the second frame 20.

Referring to fig. 1, 2, and 4, in addition to the above-described structure, a plurality of first mounting holes 100 may be formed through the leg plate 104 and the wall of the first card-mounting plate 101 that contacts the second bezel 20. The ribs 204 are formed with a plurality of second mounting holes 200 corresponding one-to-one to the first mounting holes 100. It should be understood that the above-mentioned one-to-one correspondence of the first mounting holes 100 to the second mounting holes 200 refers to one-to-one correspondence in number and space.

Referring to fig. 1, 2 and 4, the first mounting hole 100 may be a smooth hole, and the diameter of the smooth hole may be slightly larger than that of the fastening member 30, so as to ensure that the fastening member 30 can smoothly pass through the first mounting hole 100 and then be fastened to the second mounting hole 200. The second mounting hole 200 may be a smooth hole or a screw hole. When the second mounting hole 200 is a smooth hole, the fastener 30 may be a self-tapping screw (as shown in fig. 5 and 6). When the second mounting hole 200 is a threaded hole, the fastening member 30 may be a bolt having a straight thread or a tapered thread.

Referring to fig. 1, 2 and 7, as a possible implementation manner, two opposite first mounting holes 100 and second mounting holes 200 have collinear central axes, and a plurality of process holes 106 are opened through the first frame 10 along the direction of the central axes. The diameter of the process hole 106 is larger than the diameters of the first and second mounting holes 100 and 200.

Referring to fig. 1, 2 and 7, as an example, a process hole 106 may be formed through the package board and the second card board 102, and central axes of the process hole 106, the first mounting hole 100 and the second mounting hole 200 are collinear.

Referring to fig. 1, 2 and 7, in practical applications, when the first mounting hole 100 and the second mounting hole 200 have collinear central axes, self-alignment of the fastener 30 with the first mounting hole 100 and the second mounting hole 200 can be achieved when the fastener 30 is gradually screwed into the second mounting hole 200 from the first mounting hole 100. Therefore, the difficulty of the fastener 30 in aligning the first mounting hole 100 and the second mounting hole 200 at the same time can not be reduced, and the fastening force applied to the first frame 10 and the second frame can be more uniform, so that the risk of connection failure caused by stress concentration at a certain point at the connection position of the fastener 30 and the first mounting hole 100 or the second mounting hole 200 can be effectively reduced.

Referring to fig. 1, 2 and 7, a fabrication hole 106 having a larger diameter than the first and second mounting holes 100 and 200 is formed through the first frame 10 along the direction of the central axis, so as to provide a working space for screwing the fastener 30 into the first and second mounting holes 100 and 200, thereby improving the convenience of screwing the fastener 30 into the first and second mounting holes 100 and 200.

Referring to fig. 4 and 8, in one possible implementation, the first frame 10 has a first snap groove 105 for snapping the edge of the laminate 40, the first snap groove 105 has a groove wall with a plurality of first barbs 107, and the plurality of first barbs 107 are inclined toward the groove bottom of the first snap groove 105. For example, as mentioned above, the first clamping groove 105 for clamping the lamination 40 may be enclosed by the first clamping plate, the second clamping plate, the first package plate and the foot plate.

Referring to fig. 4 and 8, as an example, a plurality of first barbs 107 may be integrally formed only on the side wall that the first catching groove 105 has. The specific structure of the plurality of first barbs 107 is various, for example, the plurality of first barbs 107 are saw-toothed structure, and each tooth has a height in the direction close to the notch of the first catching groove 105 lower than a height in the direction close to the bottom of the groove. And the adjacent two teeth have a height difference.

Referring to fig. 4 and 8, in practical application, it is necessary to push the edge of the laminate from the notch of the first seizing groove 105 to the groove bottom direction, and a plurality of first barbs 107 inclined to the groove bottom direction are provided on the groove wall of the first seizing groove 105, in which case the inclined direction of the first barbs 107 is the same as the pushing direction of the laminate. In this regard, the plurality of first barbs 107 provide a guide for the laminate during its displacement toward the bottom of the groove to facilitate its insertion into the groove bottom. The first plurality of barbs 107 may also serve to resist the edge of the laminate from escaping from the first snap groove 105 after the edge of the laminate is pushed into the groove bottom.

Referring to fig. 4 and 9, as one possible implementation, the bezel further includes a first enclosure 108, the first enclosure 108 having opposing first and second sidewalls 1080, 1081 and a first bottom wall 1082 connected to the same ends of the first and second sidewalls 1080 and 1081. A first package space is enclosed by the first side wall 1080, the second side wall 1081 and the first bottom wall 1082, the first package space being for packaging an edge of the laminate. The first side wall 1080 and the second side wall 1081 have outer walls that define a first groove 1083 that engages the first barb 107.

Referring to fig. 9, as an example, the first package 108 may be a prefabricated member, for example, the first package 108 may be made of epdm, silastic or neoprene in any conventional molding manner. The first package 108 is a high performance flexible package.

Referring to fig. 4 and 9, in practical applications, in order to improve the bearing strength of the bezel, a rigid bezel is generally used, and in this case, the inner wall of the first clamping groove 105 formed in the first bezel 10 is rigid. In this regard, the first package 108 may be assembled into the first clamping slot 105 prior to assembly of the bezel with the laminate. At the moment, the high-performance flexible packaging piece can avoid the problems of product hidden cracking and generation power reduction caused by collision of the photovoltaic module. In addition, the high-performance flexible packaging part can also improve the combination tightness degree of the laminating part and the frame, and at the moment, under the condition of improving the sealing performance of the whole photovoltaic module, the probability that outdoor sewage or impurities enter the interior of the photovoltaic module through the joint of the laminating part and the first frame 10 to erode the laminating part is effectively reduced. As mentioned above, the first package 108 can be a prefabricated component, which can reduce the cleaning time required for the sealant to overflow (the overflowing sealant needs to be completely dried before cleaning) compared to the sealing method of sealant in the prior art. That is, it is possible to make it possible to assemble, i.e. deliver, thereby reducing the delivery time of the photovoltaic module. Therefore, the assembly efficiency of the photovoltaic module with the frame provided by the utility model can be improved. Furthermore, a first groove 1083 engaged with the first barb 107 is formed on the outer wall of the first side wall 1080 and the second side wall 1081, and when the first package 108 enters the first clamping groove 105, the first barb 107 is clamped in the first groove 1083. The snap action of first barb 107 and first groove 1083 may be utilized to reduce the risk of first encapsulation 108 falling out of first snap groove 105, thereby improving the connection stability of first encapsulation 108 and first snap groove 105.

As a possible implementation, referring to fig. 4, 8 and 9, a first protrusion 1084 is provided on an outer wall of the first bottom wall 1082 in a direction close to the bottom of the groove of the first clamping groove 105, the first protrusion 1084 abuts against the bottom of the groove for forming a first buffer space 113 between the bottom of the groove and the first bottom wall 1082.

Referring to fig. 4 and 9, as an example, a high performance flexible first protrusion 1084 may be integrally formed with the first side wall 1080, the second side wall 1081 and the first bottom wall 1082. When the first package 108 is fitted into the first card-holding groove 105, the first projection 1084 abuts against a groove bottom provided by the first card-holding groove 105. At this time, first buffer space 113 is formed between first bottom wall 1082 and the groove bottom of first chucking groove 105. The number of the first projections 1084 is not limited, and may be two, for example, and two first projections 1084 are distributed on both sides of the first bottom wall 1082. For another example, there may be three first protrusions 1084 distributed in a triangular shape. For another example, there may be four first protrusions 1084 distributed at four corners of a quadrangle.

Referring to fig. 4, in practical use, during insertion of the edge of the laminate into the first package space, if the force is too great, the edge of the laminate collides with the first bottom wall 1082 and the bottom of the groove provided by the first clamping groove 105. At this point, the probability of the edges of the laminate breaking due to the collision will be greatly increased. The first buffer space 113 formed between the groove bottom and the first bottom wall 1082, in turn, provides a buffer distance for such improper handling, thereby reducing the risk of the edges of the laminate breaking due to impact.

Referring to fig. 4 and 9, as a possible implementation, the first side wall 1080 and the second side wall 1081 have a plurality of second barbs 1085 on the inner wall, and the plurality of second barbs 1085 are inclined toward the first bottom wall 1082. The second barbs 1085 can be integrally formed on the inner walls of the first and second sidewalls 1080 and 1081. That is, the material of the second barb 1085 may be the same as the material of the first package 108. At this point, the second barb 1085 is a high performance flexible second barb 1085.

Referring to fig. 4 and 9, the edge of the laminate is pushed from the opening of the first packaging space to the bottom, and a plurality of second barbs 1085 inclined toward the first bottom wall 1082 are provided on the inner walls of the first side wall 1080 and the second side wall 1081, and at this time, the inclined direction of the second barbs 1085 is the same as the pushing direction of the laminate. In this regard, the second plurality of barbs 1085 provide a guiding function during the displacement of the laminate towards the bottom of the groove to facilitate the displacement of the laminate into the first package space. The second plurality of barbs 1085 can also act as a barrier to the edge of the laminate from escaping from the first package space after the edge of the laminate is pushed into the first package space.

Referring to fig. 4, as a possible implementation manner, the frame further includes a first receiving groove 109 formed to extend in a groove width direction of the first clamping groove 105, and the first receiving groove 109 is used for receiving the terminal box 70 disposed at one side of the laminate. Since the junction box is generally disposed on a back plate (backlight surface) of the laminate, the first receiving groove 109 may be opened in combination with the orientation of the back plate. That is, the opening direction of the first receiving groove 109 is consistent with the orientation of the back plate. With such an arrangement, the terminal box 70 can be accommodated in the first accommodating groove 109, that is, the terminal box 70 is encapsulated in the first frame 10, so as to reduce the problem of short service life of the terminal box 70 due to being exposed outside. It should be further explained that, when the terminal box 70 is disposed on the cover plate (light receiving surface) of the lamination, the opening direction of the first accommodating groove 109 needs to be the same as the orientation of the cover plate. From the above, it is ensured that the junction box 70 and the cable 80 are not easily failed.

Referring to fig. 4, as a possible implementation manner, the frame further includes: the assembly groove 110, the assembly groove 110 and the first receiving groove 109 are opened back to back. The fastening cover 111 extends along the longitudinal direction of the first frame 10, and in practical applications, the fastening cover 111 may be fastened to the outer side surface of the first frame 10 in a closed or semi-closed manner through the mounting groove 110. A closed or semi-closed accommodating space is formed between the buckle cover 111 and the outer side surface of the first frame 10, and the accommodating space is used for accommodating the outgoing line.

Referring to fig. 10 and 11, as an example, the buckle cover 111 may include a first buckle 1110 coupled to a foot plate included in the first bezel 10, a second buckle 1111 disposed at an end of the first buckle 1110 and inclined in a direction away from the laminated member, and an accommodation space is formed between the second buckle 1111, a portion of the first buckle 1110, and an outer side surface of the first bezel 10. The buckle cover 111 further includes a mounting plate 1112 that is positioned inside the first buckle 1110 and engages with the mounting groove 110. In order to improve the stability of the assembly plate 1112 to the assembly groove 110, a plurality of first pressure points 1100 may be provided on a groove wall of the assembly groove 110. A second pressure point 1113, which is matched to the first pressure point 1100, is provided on the mounting plate 1112. Furthermore, in order to facilitate the assembly plate 1112 to be pushed into the assembly slot 110, a slot wall of the assembly slot 110 near the lamination member may be chamfered, so as to utilize the guiding function of the chamfered portion to improve the convenience of pushing the assembly plate 1112 into the assembly slot 110.

It should be further explained that the above-mentioned buckle cover 111 can be packaged and transported independently from the frame, and thus the space occupied by the package and the transportation can be reduced, thereby improving the efficiency of the transportation. After the photovoltaic module reaches the assembly site, the buckle cover 111 can be directly buckled in the assembling groove 110, so that the buckle cover 111 can be quickly assembled with the first frame 10.

Referring to fig. 4, under the condition that above-mentioned technical scheme is adopted, hold the lead-out wire in accommodation space in unison, under the condition of standardizing the lead-out wire and walk the line, reduce the problem because of the influence photovoltaic module that the lead-out wire is in disorder and leads to beautifully spent.

Referring to fig. 12, as a possible implementation, the second rim 20 has a second clipping groove 205 for clipping the edge of the laminate, the second clipping groove 205 has a groove wall with a plurality of third barbs 206, and the plurality of third barbs 206 are inclined toward the bottom of the groove of the second clipping groove 205. So set up, can utilize the guide effect of third barb 206 to improve the convenience that the lamination body pushed into second and catches groove 205 in the process that the edge of lamination body pushed into second and catches groove 205. Moreover, the blocking action of the third barb 206 may also be used to reduce the risk of the laminate falling out of the second snap groove 205 after it has been pushed into the second snap groove 205.

Referring to fig. 12, as a possible implementation, the bezel further has a second enclosure 207, the second enclosure 207 has opposite third and fourth sidewalls 2070 and 2071 and a second bottom wall 2072 connected to the same ends of the third and fourth sidewalls 2070 and 2071, and a second enclosure space is enclosed by the third, fourth and second sidewalls 2070 and 2071 and 2072, the second enclosure space being used for enclosing the edges of the laminate. The outer walls of the third and fourth side walls 2070 and 2071 are formed with second grooves 2073 engaged with the third barbs 206. With such an arrangement, the second grooves 2073 are engaged with the third barbs 206 to realize a stable connection between the second package 207 and the second clamping groove 205. The lamination member is pushed into the second packaging space, and the lamination member is directly contacted with the inner wall of the second clamping groove 205 by using the second packaging member 207, so that the damage of the inner wall of the second clamping groove 205 to the lamination member is avoided. Sealing of the laminate edges is achieved with the second encapsulation 207, reducing the risk of laminate failure due to ingress of dirt or impurities. More importantly, since the second package 207 is generally a high-performance flexible package, direct contact between the laminate and the rigid frame can be avoided, and therefore the problems of product subfissure and generation power reduction caused by collision of the photovoltaic module can be avoided. In addition, the high-performance flexible package may also have a function of buffering and absorbing force, and based on this, when the photovoltaic module is subjected to an impact force, a portion of the impact force may be absorbed by the second package 207, thereby functioning as a photovoltaic module that is not damaged. The second package 207 also has a good sound insulation effect when applied to a sound barrier. As mentioned above, the second package 207 may also be a prefabricated component, and compared to the sealing manner of the sealant provided in the prior art, the cleaning time required by the sealant overflowing (the overflowing sealant needs to be completely air-dried before being cleaned) can be reduced, so as to reduce the lead time of the photovoltaic module.

Referring to fig. 12, as a possible implementation manner, a second protrusion 2074 is disposed on an outer wall of the second bottom wall 2072 in a direction close to the bottom of the groove of the second clamping groove 205, and the second protrusion 2074 abuts against the bottom of the groove to form a second buffer space 211 between the bottom of the groove and the second bottom wall 2072. So configured, when the force is not applied to the assembly of the laminate, the second buffer space 211 can extend the buffer distance between the laminate and the bottom of the groove of the second clamping groove 205, so as to reduce the risk of the laminate breaking due to improper force.

Referring to fig. 12, as a possible implementation, the third and fourth sidewalls 2070 and 2071 have a plurality of fourth barbs 2075 on their inner walls, and the plurality of fourth barbs 2075 are inclined toward the second bottom wall 2072. So configured, the guiding effect of the fourth barbs 2075 is utilized to improve the convenience of the assembly of the laminate to the second packaging space. The blocking action with the fourth barbs 2075 reduces the risk of the laminate falling out of the second encapsulating space.

Referring to fig. 13 to 15, as a possible implementation, in the case that the end portion of the second frame 20 is mechanically connected to the first frame near the end portion thereof, the second frame 20 further includes an overflow plate 208 extending toward the end portion of the first frame and covering the end portion of the first frame. In the foregoing, the first clamping plate and the second clamping plate included in the first frame have the cavity, and if the end of the first frame is not sealed, in practical applications, dust, rainwater, etc. are likely to gather in the cavity, and at this time, the corrosion rate of the first frame will be increased, thereby affecting the service life of the first frame. The overflow plate 208 can effectively cover the end of the first frame to effectively prevent the dust or rain water from entering the cavity. The overflow plate 208 may be integrally formed with the second rim 20. The length of the latch protrusion 209 provided on the second frame 20 may be equal to the length of the second frame 20, that is, not continuously extending in the length direction of the overflow plate 208.

Referring to fig. 16, the difference from the previous possible implementation is that the clamping protrusion 209 provided on the second frame 20 extends to the end of the overflow plate 208, and thus the clamping stability between the second frames 20 can be improved.

In a second aspect, referring to fig. 3, an embodiment of the present invention further provides a photovoltaic module, which includes a laminated part and a frame clamped at an edge of the laminated part, where the frame is provided in the first aspect of the embodiment of the present invention and/or in any implementation manner of the first aspect of the embodiment of the present invention.

Compared with the prior art, the beneficial effects of the photovoltaic module provided by the embodiment of the utility model are the same as those of the frame in the technical scheme, and the details are not repeated here.

In a third aspect, an embodiment of the present invention further provides a photovoltaic module, which includes a plurality of photovoltaic modules distributed in a matrix and connected together, where the photovoltaic modules are the photovoltaic modules provided in the first aspect of the present invention and/or any implementation manner of the first aspect of the present invention.

The photovoltaic modules described above may be in an M × N matrix, for example, a 2 × 2, 3 × 3, or 4 × 4 square matrix. For example, a 2 × 3, 3 × 4, or 4 × 5 rectangular array. Of course, not limited to the above-listed array.

As for the connection method between the photovoltaic modules, there are various methods, and several specific connection methods are listed below, it should be understood that the following are only for explanation and not for limitation.

As a possible implementation mode, two adjacent photovoltaic modules are clamped together, and the arrangement has the advantages of positioning and convenience in clamping. When the photovoltaic module arranged in this way is applied to a sound barrier, after noise/sound is transmitted to the photovoltaic module, the sound is not transmitted linearly but diffracted at the connecting part of the photovoltaic module, so that the transmission path of the noise/sound is prolonged, and the sound insulation effect can be improved under the condition of improving the loss of the noise/sound.

The following will describe the clamping manner between the photovoltaic modules in detail by taking the photovoltaic modules in the same column as an example of a sub-photovoltaic module, and it should be understood that the following list is only for explanation and not for limitation.

Referring to fig. 17 and 18, in a first example, when a plurality of photovoltaic modules are sequentially assembled along the extending direction of the first frame to form a column of sub-photovoltaic modules, the second frames 20 of two adjacent photovoltaic modules need to be clamped together. At this time, the clamping protrusion 209 may be integrally disposed on the second frame 20 included in the lower photovoltaic module (in this case, the second frame 20 located above the photovoltaic module), and correspondingly, the clamping groove 210 may be integrally disposed on the second frame 20 included in the upper photovoltaic module (in this case, the second frame 20 located below the photovoltaic module). And then the clamping protrusions 209 are inserted into the clamping grooves 210, so that the assembly of two adjacent photovoltaic modules is realized.

Referring to fig. 19, the second example is different from the first example in that a clamping groove 210 is integrally formed on the second rim 20 included in the lower photovoltaic module (in this case, the second rim 20 located above the photovoltaic module), and correspondingly, a clamping protrusion 209 is integrally formed on the second rim 20 included in the upper photovoltaic module (in this case, the second rim 20 located below the photovoltaic module).

Referring to fig. 20, the third example is different from the first example in that two clamping protrusions 209 are integrally and alternately arranged on the second frame 20 (in this case, the second frame 20 located above the photovoltaic module) included in the photovoltaic module located below, and correspondingly, two clamping grooves 210 are integrally and alternately arranged on the second frame 20 (in this case, the second frame 20 located below the photovoltaic module) included in the photovoltaic module located above.

As a possible implementation mode, two adjacent photovoltaic modules are detachably connected together through the adaptor, and the arrangement can increase the connection strength of the two adjacent photovoltaic modules, so that the connection stability is improved.

Similarly, the following description will be made in detail with reference to the photovoltaic modules in the same column as an example of a sub-photovoltaic module, and it should be understood that the following description is only for explanation and not for limitation.

Referring to fig. 21, in a first example, when a plurality of photovoltaic modules are assembled in sequence along the extending direction of a first frame to form a column of sub-photovoltaic modules, the second frames 20 of two adjacent photovoltaic modules need to be clamped together. At this time, the adaptor 50 may be disposed between the second frame 20 included in the lower photovoltaic module (in this case, the second frame 20 located above the photovoltaic module) and the second frame 20 included in the upper photovoltaic module (in this case, the second frame 20 located below the photovoltaic module). Specifically, the adaptor 50 has a first connecting portion 501 located between two adjacent photovoltaic module connecting ends, and a second connecting portion 502 respectively fastened to two side edges included in two photovoltaic modules. That is, the adaptor 50 may be an i-shaped adaptor.

And a mounting member 60, wherein the mounting member 60 has a first end and a second end opposite to each other, the first end is connected to the building facade, and the second end is connected to the first frame 10 of the photovoltaic module which comprises the photovoltaic modules and is positioned in the same column.

In practical applications, the photovoltaic modules in the same row include a first frame 10 carried by the second end of the mounting member 60, and the first end of the mounting member 60 is fastened to the building facade. The photovoltaic modules in the same column comprise second frames 20 which are connected together to realize the connection of the photovoltaic modules in the same column with the building facade. Due to the connection of the second rims 20 included in the adjacent photovoltaic modules, the photovoltaic module located below can provide a supporting force for the photovoltaic module located above, and the photovoltaic module located below is compressed under the effect of the weight of the photovoltaic module located above. Based on this, can mutual transmission atress between the photovoltaic module that interconnect is in the same place, can improve the connection compactness between the photovoltaic module to improve the connection stability between the photovoltaic module. When the photovoltaic system is applied to the sound barrier, the sound insulation effect of the sound barrier can be improved due to the mutual compaction effect of the photovoltaic modules.

In one possible implementation, the mounting part 60 includes a first side plate 600 and a second side plate 601 which are opposite to each other, and a connecting plate 602 whose two ends are respectively connected to the first side plate 600 and the second side plate 601.

In practical applications, the frame is generally an aluminum alloy frame, and the mounting member 60 is generally an i-beam, and if the aluminum alloy frame and the i-beam are directly inserted together, electrochemical corrosion is easily generated. Based on this, a flexible rubber strip (not shown in the figure) can be arranged on the inner wall of the mounting groove 112 to effectively isolate the aluminum alloy frame from the i-steel, so as to avoid the generation of electrochemical corrosion. Moreover, the flexible rubber adhesive tape also has a buffering effect, and can absorb the installation error between the aluminum alloy frame and the I-shaped steel so as to optimize the installation effect. And, under the condition of avoiding aluminum alloy frame and I-steel direct contact, can effectually avoid the noise that produces because of rigid contact and take place like phenomenon such as colliding with or falling lacquer. When the photovoltaic module is applied to the sound barrier, the flexible rubber adhesive tape also has a sound insulation effect.
