[0043] The present invention also provides examples of various specific processes and materials, but those skilled in the art will recognize the applicability of other processes and / or other materials.

[0044] With reference to FIGs. 1 and 2, the present invention discloses an installation device for mounting a photovoltaic (PV) mounting system rail 20 to a rail connector 30, comprising an assembly portion 100, elastic press portions 200, and elastic clamping portions 300.

[0045] The installation device disclosed in this embodiment is positioned between the PV mounting system rail 20 and the rail connector 30, so that a first assembly surface 110 of the assembly portion 100 faces the PV mounting system rail 20, and a second assembly surface 120 faces the rail connector 30. The first assembly surface 110 is provided with the elastic press portions 200, and the second assembly surface 120 provided with the elastic clamping portions 300.

[0046] A first end of each of the elastic press portions 200 is connected to the first assembly surface 110, and a second end of each of the elastic press portions 200 extends in a direction away from the first assembly surface 110; a surface of each of the elastic press portions 200 facing the first assembly surface 110 forms a pressing angle 210 with the first assembly surface 110, and the pressing angle 210 is an acute angle; each of the elastic clamping portions 300 is arranged on the second assembly surface 120 and is fastened into a slot 31 provided on the rail connector 30.

[0047] When the installation device is in use, the elastic clamping portions 300 are first being pressed into the slot 31 of the rail connector 30 so that the installation device is engaged with the slot 31. The elastic clamping portions 300 elastically deform while being pushed into the slot 31, and the elastic potential energy of the elastic clamping portions 300 generate a clamping force against the slot 31 to maintain the elastic clamping portions 300 tightly fastened into the slot 31, thereby fixing the installation device to the rail connector 30. Then, the PV mounting system rail 20 is slid on the rail connector 30 along a direction along two ends of each of the elastic press portions 200, such that a rail plate 21 of the PV mounting system rail 20 presses against the elastic press portions 200, thereby compressing the elastic press portions 200, and the elastic press portions 200 being pressed have elastic potential energy that generates a pressing force against the PV mounting system rail 20, thereby fixing the PV mounting system rail 20 to the rail connector 30 and preventing relative displacement, thus achieving a fixed installation.

[0048] Compared with the prior art, the installation device provided by the present invention allows precise mounting of the PV mounting system rail 20 to the rail connector 30 without the use of other auxiliary tools and without the need to mark any fastening position during assembly, thereby ensuring installation accuracy and rapid installation, thus improving installation efficiency.

[0049] The following are specific embodiments of the installation device described above.

[0050] With reference to FIG. 4, the elastic clamping portions 300 comprise a first elastic arm 310 and a second elastic arm 320, both capable of elastic deformation. One end of each of the first elastic arm 310 and the second elastic arm 320 is connected to the second assembly surface 120, and another end of each of the first elastic arm 310 and the second elastic arm 320 extends away from the second assembly surface 120; the first elastic arm 310 and the second elastic arm 320 are fastened to two opposing side walls 32 of the slot 31 respectively, thus achieving fastening of the elastic clamping portions 300 and the rail connector 30. [0051 ] To improve the stability of the fastening of the elastic clamping portions 300 and the rail connector 30, the first elastic arm 310 and the second elastic arm 320 are provided with a first clamping position 313 and a second clamping position 323 respectively; the first elastic arm 310 comprises a first connecting portion 311 and a first clamping portion 312; one end of the first connecting portion 311 is connected to the second assembly surface 120, and another end of the first connecting portion 311 is connected to a first end of the first clamping portion 312, so as to form the first clamping position 313 for engaging a respective one of the side walls 32 at a connection point between the first connecting portion 311 and the first clamping portion 312. The second elastic arm 320 comprises a second connecting portion 321 and a second clamping portion 322; one end of the second connecting portion 321 is connected to the second assembly surface 120, and another end of the second connecting portion 321 is connected to a first end of the second clamping portion 322, so as to form the second clamping position 323 for engaging a respective one of the side walls 32 at a connection point between the second connecting portion 321 and the second clamping portion 322. In addition, a distance between the first clamping position 313 and the second clamping position 323 must not be less than a distance between the two opposing side walls 32, so that the first elastic arm 310 and the second elastic arm 320 can have elastic deformation, thereby generating a strong clamping force of the first clamping position 313 and the second clamping position 323 against the two opposing side walls 32. Furthermore, a distance between a second end of the first clamping portion 312 and a second end of the second clamping portion 322 is greater than the distance between the first clamping position 313 and the second clamping position 323, so as to prevent the first clamping position 313 and the second clamping position 323 from disengaging with the two opposing side walls 32 during installation, thereby avoiding loosening or detachment of the installation device from the rail connector 30.

[0052] Further, as shown in FIG. 4, to facilitate quick and convenient installation of the elastic clamping portions 300 into the slot 31 of the rail connector 30, the elastic clamping portions 300 are provided with a first guiding portion 314 and a second guiding portion 324; a first end of the first guiding portion 314 is connected to the second end of the first clamping portion 312, and a first end of the second guiding portion 324 is connected to the second end of the second clamping portion 322; a distance between a second end of the first guiding portion 314 and a second end of the second guiding portion 324 is not greater than the distance between the two opposing side walls 32, so that the first guiding portion 314 and the second guiding portion 324 can quickly slide into the slot 31.

[0053] As shown in FIG. 3, an end face of the second end of each of the elastic press portions 200 further comprises a piercing portion 220, which comprises a plurality of protrusions 221 spaced apart from each other. Thus, not only the installation device disclosed in this embodiment achieves rapid installation between the PV mounting system rail 20 and the rail connector 30, but also the plurality of protrusions 221 of each piercing portion 220 can pierce through a non-conductive layer (an oxide film generated on a surface of aluminum alloy after oxidation of a positive electrode thereof) on a surface of the PV mounting system rail 20 so as to be in contact with a conductive portion of the PV mounting system rail 20, thereby achieving electrical conductivity between two connected PV mounting system rails 20. To ensure effective piercing of each piercing portion through the non-conductive layer on the surface of the PV mounting system rail 20, a tip of each of the plurality of protrusions 221 is reduced in surface area to increase contact force with the surface of the PV mounting system rail 20.

[0054] Referring to FIGs. 2 and 6, to achieve connection and fixation of two PV mounting system rails 20 on one rail connector 30, a number of said elastic press portions 200 in the installation device is two, distributed at two ends of the first assembly surface 110 along a longitudinal direction according to which the PV mounting system rail 20 extends. Second ends of the elastic press portions 200 extend towards each other so that gaps defined by pressing angles 210 of the two elastic press portions 200 face towards each other, so that two PV mounting system rails 20 can be slid onto the rail connector 30 from two opposite ends of the rail connector 30 respectively and thus being fixed through the installation device.

[0055] After the PV mounting system rail 20 is mounted onto the rail connector 30, to prevent displacement of the PV mounting system rail 20 on the rail connector 30 along a longitudinal direction defined by the two ends of a respective one of the elastic press portions 200, the first assembly surface 110 of the assembly portion 100 is also provided with positioning portions 400. One end of each of the positioning portions 400 is connected to the first assembly surface 110, and another end of each of the positioning portions 400 extends away from the first assembly surface 110. Each of the positioning portions 400 is located downstream of a respective one of the elastic press portions 200 at a position more proximal to the second end than the first end of the respective one of the elastic press portions 200 along an installation direction of the PV mounting system rail 20, thereby blocking longitudinal movement of the PV mounting system rail 20 on the rail connector 30.

[0056] Furthermore, as shown in FIGs 1 and 6, when two PV mounting system rails 20 are connected and fixed on a same rail connector 30, a number of the positioning portions 400 is two; the positioning portions 400 are located between the two elastic press portions 200 and positioned on two sides of the first assembly surface 110 along a direction transverse to the longitudinal direction which the two PV mounting system rails 20 extend. The two positioning portions 400 further prevent displacement of the two PV mounting system rails 20 on the rail connector 30, and assist in positioning of the two PV mounting system rails 20 on the rail connector 30 during installation of the two PV mounting system rails 20 on the rail connector 30 to avoid positional deviation between the two PV mounting system rails 20 and the rail connector 30 during installation.

[0057] Additionally, the two positioning portions 400 may be positioned on a same plane, thereby improving consistency and appearance of a connecting seam between the two PV mounting system rails 20 after the two PV mounting system rails 20 are installed on the rail connector 30, and also preventing excessively large gap that may allow foreign objects to enter and affect the two PV mounting system rails 20 and the rail connector 30 after the two PV mounting system rails 20 are installed on the rail connector 30.

[0058] The present invention also discloses an installation structure for photovoltaic (PV) mounting system rails, including PV mounting system rails 20 and a rail connector 30, wherein the PV mounting system rails 20 and the rail connector 30 are fixedly installed through the above installation device.

[0059] Since the installation structure includes the above installation device, the installation structure also possesses all the technical effects of the installation device, which will not be repeated herein.

[0060] To enhance the structural strength and manufacturing efficiency of the installation device, the installation device is integrally manufactured by stamping. Moreover, to ensure good technical performance of the installation device, the material of the installation device is stainless steel or spring steel, or other materials selected as needed by those skilled in the art, and all these possible materials are not exhaustively listed herein. However, it is understood that the material making the installation device must be elastically deformable and electrically conductive to realize all technical effects of the installation device. Alternatively, those skilled in the art may design the manufacturing method or choose the material making the installation device as required. The present invention will not exhaustively list out all possible manufacturing methods and materials making the installation device. [0061 ] The above embodiments and drawings do not limit the form and style of the product of the present invention. Any appropriate changes or modifications made by those skilled in the art shall be considered within the scope of the present invention.
