Fig. 1 to 7 illustrate embodiments 1 to 5 of a frame 100 for a photovoltaic module according to the present application, wherein the upper portion of the frame 100 of the present application has a mounting groove 101 opened toward the inside, the middle portion of the frame 100 has a mounting portion 130, and the lower portion of the frame 100 has a connection groove 102 opened toward the inside, as shown in the drawings.
The mounting groove 101 of the frame 100 is used to mount the photovoltaic laminates 200, and as shown in fig. 8, the edges of each photovoltaic laminate 200 are respectively mounted in the mounting groove 101 of the frame 100. As will be appreciated by those skilled in the art, four sides of each photovoltaic laminate 200 are mounted within the frame 100, and for clarity of illustration, fig. 8 does not show the frame 100 for mounting the other two sides of the photovoltaic laminate 200.
The mounting portion 130 of the frame 100 is configured to cooperate with the second connecting piece 300 to realize end-to-end docking of the two frames 100, as shown in fig. 9, two ends of the second connecting piece 300 are adapted to be inserted into the piece mounting portions 130 of the two frames 100 respectively, so as to connect the two frames 100.
The connecting grooves 102 of the frames 100 are used for being matched with the first connecting piece 400 to realize connection of the two frames 100 arranged back to back, as shown in fig. 10, when the B faces of the frames 100 of the two photovoltaic modules are arranged in a fitting manner, the joint parts 420 at two ends of the first connecting piece 400 can be respectively inserted into the connecting grooves 102 of the adjacent two frames 100, the connecting parts 410 connecting the two joint parts 420 are suitable for extending from the opening of one connecting groove 102 to the opening of the other connecting groove 102 through the C faces of the two frames 100, so that two ends of the connecting parts 410 are respectively connected with the two joint parts 420, and the relative separation of the two frames 100 is limited by the first connecting piece 400, namely, the connection of the two photovoltaic modules is realized.
According to the application, the connecting groove 102 is arranged at the lower part of the frame 100, so that the two frames 100 attached to the B surface can be quickly connected, and the assembly efficiency of a plurality of photovoltaic modules can be improved. In addition, the mounting groove 101, the mounting portion 130 and the connecting groove 102 are sequentially arranged from top to bottom, and the mounting portion 130 is arranged in the middle, so that the load performance of the frame 100 is improved.
The bezel 100 of the present application is further described in conjunction with various embodiments below.
[ Example 1]
As shown in fig. 1, the rim 100 includes a side wall 110, and upper and lower walls 120 and 140 at upper and lower ends of the side wall 110, the upper and lower walls 120 and 140 each extending along one side of the side wall 110 and being perpendicular to the side wall 110. The mounting portion 130 is connected to the side wall 110 and is located between the upper wall 120 and the lower wall 140. The mounting portion 130 forms a mounting cavity 136 penetrated at both ends so that the second connector 300 is adapted to be inserted into the mounting cavity 136 from the end of the mounting portion 130. It should be noted that the second connecting piece 300 includes two plugging portions 310, the included angle of the two plugging portions 310 is 90 °, and the two plugging portions 310 are adapted to be inserted into the mounting cavities 136 from one ends of the mounting portions 130 of the two frames 100, respectively, so that the two frames 100 are connected end to end through the second connecting piece 300, and the included angle of the two frames 100 after connection is 90 °.
The lower wall 140 extends horizontally perpendicular to the side walls 100 so that the lower wall 140 can be stably placed on a plane, which is convenient for installation, and in addition, is advantageous in simplifying the processing of the rim 100.
The mounting portion 130 includes a top surface 131, a bottom surface 132, and an inner side surface 133, and the top surface 131, the bottom surface 132, the inner side surface 133, and the side wall 110 define a mounting cavity 136, and a cross section of the mounting cavity 136 is rectangular.
The upper wall 120 and the top surface 131 of the mounting portion 130 form a mounting groove 101 therebetween, and the lower wall 140 and the bottom surface 132 of the mounting portion 130 form a connecting groove 102 therebetween. In other words, the upper wall 120 is the a-side of the bezel 100, the side wall 110 is the B-side of the bezel 100, and the lower wall 140 is the C-side of the bezel 100.
The top surface 131 of the mounting portion 130 extends to an end far from the side wall 110 to form an extension portion 135, the extension portion 135 protrudes inward from the inner side surface 133 of the mounting portion 130, and the distance from the end of the extension portion 135 to the side wall 110 is greater than the distance from the end of the upper wall 120 to the side wall 110. By providing the extension 135, the mounting stability of the photovoltaic laminate 200 is advantageously improved, while also avoiding the oversized mounting portion 130, resulting in material wastage.
In other words, the top of the mounting portion 130 is extended in a direction away from the side wall 110 such that the length of the top of the mounting portion 130 is greater than the length of the upper wall 120.
Further, the length of the inner side of the lower wall 140 does not exceed the length of the extension 135, in other words, the distance from the end of the lower wall 140 to the side wall 110 does not exceed the distance from the end of the extension 135 to the side wall 110, which is beneficial to saving materials and facilitating the installation of the first connector 400, and if the lower wall 140 is too long, the length of the first connector 400 will increase, which is not beneficial to the installation of the first connector 400. Of course, the length of the inner side of the lower wall 140 is not too short, which would be detrimental to the load carrying performance of the bezel 100. Preferably, the distance from the end inside the lower wall 140 to the side wall 110 is not smaller than the distance from the inner side 133 of the mounting portion 130 to the side wall 110.
[ Example 2]
As shown in fig. 2, 3 and 4, the frame 100 of embodiment 2 is different from embodiment 1 in that the end of the lower wall 140 away from the side wall 110 extends upward to form a protrusion 141, the end of the bottom 132 of the mounting portion 130 away from the side wall 110 extends downward to form a tooth 134, and the tooth 134 is opposite to the protrusion 141, so as to form an inlet of the connecting slot 102 therebetween. The teeth 134 and the protrusions 141 serve to limit the first connector 400.
As shown in fig. 10 and 11, when the first connecting member 400 connects two frames 100, different positions of the engaging portion 420 are limited by the tooth portion 134 and the protruding portion 141, which is beneficial to improving stability of the first connecting member 400 after being mounted, so that the first connecting member 400 is not easy to fall off.
In addition, the provision of the protruding portion 141 and the tooth portion 134 is also advantageous in improving the load performance of the bezel 100.
The specific shapes of the protruding portion 141 and the tooth portion 134 are not limited in the present application, for example, the cross sections of the protruding portion 141 and the tooth portion 134 may be rectangular, semicircular, triangular, etc.
[ Example 3]
As shown in fig. 5, the frame 100 of embodiment 3 is different from embodiment 1 in that the end of the lower wall 140 away from the side wall 110 extends upward to form a protrusion 141. The protruding portion 141 is mainly used for limiting the joint portion 420 of the first connecting piece 400 when the first connecting piece 400 is connected with the two frames 100, so that stability of the first connecting piece 400 after being mounted is improved, and the first connecting piece 400 is not easy to fall off.
In addition, the provision of the boss 141 is also advantageous in improving the load performance of the bezel 100.
[ Example 4]
As shown in fig. 6, the frame 100 of embodiment 4 is different from embodiment 1 in that the bottom surface 132 of the mounting portion 130 extends downward from an end of the side wall 110 to form a tooth portion 134. The tooth portion 134 also has a function of limiting the joint portion 420 of the first connecting piece 400 when the first connecting piece 400 connects the two frames 100, which is beneficial to improving stability of the first connecting piece 400 after installation, so that the first connecting piece 400 is not easy to fall off.
In addition, the provision of the teeth 134 is also advantageous in improving the load performance of the bezel 100.
[ Example 5]
As shown in fig. 7, the frame of embodiment 5 is different from that of embodiment 2 in that the bottom surface 132 of the mounting portion 130 is inclined such that the distance between the bottom surface 132 of the mounting portion 130 and the lower wall 140 gradually increases from the side wall 110 to the inside, in other words, the distance between the bottom of the mounting portion 130 and the lower wall 140 gradually increases in the extending direction of the lower wall 140. The bottom surface 132 is inclined, so that the connecting groove 102 is more attached to the first connecting piece 400, and the bottom surface 132 of the mounting portion 130 can limit the joint portion 420 of the first connecting piece 400, so that the stability of the first connecting piece 400 after being mounted is further improved, and the first connecting piece 400 is not easy to fall off.
Furthermore, the inclined arrangement of the bottom surface 132 of the mounting portion 130 is also advantageous for further improving the load performance of the frame 100.
The present application also provides a photovoltaic module including the photovoltaic laminate 200, a plurality of frames 100 disposed at the circumferential side of the photovoltaic laminate 200, and a plurality of second connectors 300 for connecting the frames 100. The photovoltaic laminate 200 is generally rectangular, and in this case, the photovoltaic module generally includes four frames 100 disposed around the photovoltaic laminate 200, and the four frames 100 are connected end to end by four second connectors 300. It should be noted that the four rims 100 generally include a pair of longer long rims and a pair of shorter short rims, and of course, the present application is not limited to the specific shape of the photovoltaic laminate 200, and one skilled in the art can rotate the rims 100 by an appropriate amount and length according to the actual shape of the photovoltaic laminate 200. In addition, the manner of connecting the two frames 100 by using the second connecting member 300 belongs to the prior art in the field, and the specific structure and shape of the second connecting member 300 can refer to the prior art in the field. In one embodiment, the second connector 300 includes two plugging portions 310, and the two plugging portions 310 are adapted to be plugged and mated with the mounting portions 130 of the two frames 100, respectively, that is, inserted into the mounting cavities 136 of the mounting portions 130, so that the two frames 100 are connected end to end by the second connector 310.
It should be noted that, since the first connector 400 needs to be inserted from the end of the frame 100, in some embodiments, the first connector 400 may be installed first and then the second connector 300 may be installed, and in other embodiments, after the second connector 300 connects the two frames 100, the lower end surface of the second connector 300 is not lower than the bottom surface 132 of the mounting portion 130, so as to avoid interference between the lower end of the second connector 300 and the first connector 400.
The application also provides a photovoltaic power generation system, which comprises a plurality of adjacently arranged photovoltaic modules and a first connecting piece 400 for connecting the adjacent photovoltaic modules, wherein the frame 100 provided by the application is adopted by the frame of each photovoltaic module. The first connecting piece 400 is suitable for the B face of a frame to be tightly connected with two photovoltaic modules, after the two photovoltaic modules are connected through the first connecting piece 400, the frames of the two photovoltaic modules are almost gapless, so that the space utilization rate is greatly improved, and the photovoltaic modules are arranged in a limited space.
It should be noted that, in fig. 10 and 11, only one embodiment of the frame 100 is used, but it does not mean that only the frame 100 of the embodiment of the drawings can be mated with the first connector 400, and each embodiment of the frame 100 provided in the present application can be mated with the first connector 400, so as to connect through the first connector 400.
As shown in fig. 10 and 11, the first connector 400 includes a connecting portion 410 and engaging portions 420 extending upward and opposite from two ends of the connecting portion 410, and the engaging portions 420 at two ends of the first connector 410 are adapted to penetrate into the connecting grooves 102 of the two frames 100 respectively, so as to connect the two frames 100 by the first connector 400.
As shown in fig. 12 and 13, a transverse limiting cavity 401 is formed between the two joint portions 420 and the connecting portion 410, a longitudinal limiting cavity 402 is formed between the two joint portions 420, and the transverse limiting cavity 401 and the longitudinal limiting cavity 402 penetrate back and forth, so that when the side walls 110 of the two frames 100 are arranged in a fitting manner, the two fitted side walls 110 are suitable for penetrating through the longitudinal limiting cavity 402, and the lower walls 140 on two sides are suitable for being inserted into the transverse limiting cavity 401.
By reasonably controlling the dimensions of the transverse spacing cavity 401 and the longitudinal spacing cavity 402, the longitudinal dimension of the transverse spacing cavity 401 is slightly greater than the thickness of the lower wall 140, and the transverse dimension of the longitudinal spacing cavity 402 is slightly greater than twice the thickness of the side wall 110, it can be ensured that the first connecting piece 400 can be smoothly inserted into the connecting slot 102 of the two frames 100, and no transverse and longitudinal relative displacement basically occurs between the two frames 100 after connection.
Further, the joint 420 includes a vertical section 421, a transition section 422, a longitudinal abutting section 423 and a transverse abutting section 424 extending from the end of the connecting section 410 in sequence, a longitudinal limiting cavity 402 is formed between the longitudinal abutting sections 423 of the two joint 420, a transverse limiting cavity 401 is formed between the transverse abutting section 424 and the connecting section 410, a protruding portion accommodating cavity 403 is formed between the end of the transverse abutting section 424 and the vertical section 421, and when the first connecting piece 400 connects the two frames 100, the protruding portion 141 at one end of the lower wall 140 is adapted to be inserted into the protruding portion accommodating cavity 403.
It should be noted that, the free end of the lateral abutment section 424 of the first connector 400 is opposite to the protrusion 141 on the lower wall 140 of the frame 100, and the protrusion 141 can limit the lateral abutment section 424, which is beneficial to increasing the connection stability of the first connector 400. The transition section 422 of the first connecting piece 400 is opposite to the bottom surface 132 of the mounting portion 130 of the frame 100, and the bottom surface 132 or the teeth 134 on the bottom surface 132 can be limited with the transition section 422, so that the connection stability of the first connecting piece 400 is improved.
In some embodiments, when the first connector 400 connects two adjacent frames 100, at least a portion of the surface of the engaging portion 420 of the first connector 400 is attached to the bottom of the mounting portion 130, as shown in fig. 14. Limiting the coupling portion 420 through the bottom surface of the mounting portion 130 is beneficial to improving the connection stability of the first connector 400.
When the frame 100 receives a larger external force, the lower wall 140, the side wall 110, the protruding portion 141, the tooth portion 134 and the bottom surface 132 of the mounting portion for limiting the first connecting piece 400 can limit the deformation of the first connecting piece 400, so as to avoid the failure caused by the larger deformation of the first connecting piece 400.
In some embodiments, in order to reduce the friction between the first connector 400 and the frame 100 when being mounted, the longitudinal abutting section 424 is disposed obliquely, so that when the first connector 400 connects the two frames 100, the lower end of the longitudinal abutting section 424 is far away from the side wall 110 located in the longitudinal limiting cavity 402, that is, the friction between the first connector 400 and the frame 100 is reduced by reducing the contact area, so as to improve the mounting efficiency of the first connector 400.
In some embodiments, in order to reduce the friction between the first connecting piece 400 and the frame 100 during installation, the transition section 422 extends from the middle to the vertical section 421 and the longitudinal abutting section 423 obliquely downward from two sides, so that when the first connecting piece 400 connects the two frames 100, two ends of the transition section 422 are both far away from the bottom surface 132 of the installation portion 130, and the middle of the transition section 422 is close to the bottom surface 132 of the installation portion 130, so that the transition section 422 can be limited by the bottom surface 132, and installation difficulty caused by overlarge contact area can be avoided.
It should be noted that, the first connecting piece 400 may be formed by bending a metal plate, and the processing manner is simple.
