[0045] Furthermore, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0046] 1 and 2 , the present invention discloses a clamping device for achieving installation and fixation of a photovoltaic track 20 and a track connector 30 , which includes an assembly portion 100 , an elastic pressing portion 200 and an elastic clamping portion 300 .

[0047] The clamping device disclosed in this embodiment is located between the photovoltaic track 20 and the track connector 30, so the first assembly surface 110 of the assembly part 100 faces the photovoltaic track 20, and the second assembly surface 120 of the assembly part 100 faces the track connector 30, and the first assembly surface 110 and the second assembly surface 120 are respectively provided with an elastic pressing portion 200 and an elastic clamping portion 300.

[0048] The first end of the elastic pressing portion 200 is connected to the first assembly surface 110, and the second end of the elastic pressing portion 200 extends away from the first assembly surface 110. A pressing angle 210 is formed between the surface of the elastic pressing portion 200 facing the first assembly surface 110 and the first assembly surface 110, and the pressing angle 210 is an acute angle. The elastic clamping portion 300 is disposed on the second assembly surface 120 and is mounted in the clamping slot 31 of the track connector 30 by a clamping connection.

[0049] When the above-mentioned clamping device is used, the elastic clamping portion 300 is first pressed into the clamping slot 31 of the track connector 30 by pressing, so that the elastic clamping portion 300 is engaged with the clamping slot 31 . The elastic clamping portion 300 in the clamping slot 31 has elastic potential energy due to elastic deformation, so the elastic clamping portion 300 and the clamping slot 31 generate a clamping force, so that the elastic clamping portion 300 is in a clamped and fastened state in the clamping slot 31, thereby realizing the fixed installation of the clamping device disclosed in this embodiment on the track connector 30; then the photovoltaic track 20 is slid into the track connector 30 along the direction from the first end to the second end of the elastic pressing portion 200, at this time, the track plate 21 of the photovoltaic track 20 presses down the elastic pressing portion 200, and the elastic pressing portion 200 is compressed by the track plate 21 and has elastic potential energy, so that a clamping force is generated between the elastic pressing portion 200 and the photovoltaic track 20, thereby fixing the photovoltaic track 20 on the track connector 30, preventing the relative displacement between the photovoltaic track 20 and the track connector 30, thereby realizing the installation and fixation of the photovoltaic track 20 and the track connector 30.

[0050] Compared to the prior art, the clamping device provided by the present invention can be installed with the photovoltaic track 20 and the track connector 30 without the need for additional auxiliary tools, and there is no need to mark the fastening positions during the assembly process, thereby ensuring the accurate installation of the photovoltaic track 20 and the track connector 30. Therefore, the clamping device provided by the present invention realizes the rapid installation of the photovoltaic track and the track connector, thereby improving the installation efficiency of the photovoltaic track and the track connector.

[0051] The following shows a specific embodiment of the above-mentioned clamping device.

[0052] Referring to Figure 4, the above-mentioned elastic clamping portion 300 includes a first elastic arm 310 and a second elastic arm 320 with elastic deformation ability, and one end of the first elastic arm 310 and the second elastic arm 320 are both connected to the second assembly surface 120, and the other end extends in the direction away from the second assembly surface 120, and the first elastic arm 310 and the second elastic arm 320 are respectively clamped to the two opposite clamping side walls 32 of the clamping slot 31, thereby realizing the elastic clamping portion 300 and the track connector 30 being assembled together in a clamping manner.

[0053] The first and second clamping portions 313 and 323 are connected to each other to form a first connection between the first and second clamping portions 311 and 312, respectively. The connection between the parts 322 forms a second locking position 323 for locking the other locking side wall 32; secondly, it is also necessary to ensure that the distance between the first locking position 313 and the second locking position 323 is not less than the distance between the two opposite locking side walls 32, so that the first elastic arm 310 and the second elastic arm 320 produce elastic deformation, thereby making the first locking position 313 and the second locking position 323 and the two opposite locking side walls 32 produce a stronger clamping force; furthermore, the distance between the second end of the first locking portion 312 and the second end of the second locking portion 322 is greater than the distance between the first locking position 313 and the second locking position 323, so as to prevent the two opposite locking side walls 32 from falling off from the first locking position 313 and the second locking position 323 during the locking process, thereby avoiding the phenomenon of the clamping device loosening or even detaching from the track connector 30.

[0054] Secondly, referring to Figure 4, in order to make the elastic clamping part 300 conveniently and quickly installed in the clamping slot 31 of the track connector 30, the above-mentioned elastic clamping part 300 is provided with a first guide part 314 and a second guide part 324, and the first ends of the first guide part 314 and the second guide part 324 are respectively connected to the second ends of the first clamping part 312 and the second clamping part 322, and the distance between the second ends of the first guide part 314 and the second guide part 324 is not greater than the distance between the two opposite clamping side walls 32, so that the first guide part 314 and the second guide part 324 can quickly slide into the clamping slot 31.

[0055] Referring to Figure 3 , the second end surface of the elastic compression portion 200 further includes a protruding portion 220, which includes a plurality of spaced-apart protrusions 221. Therefore, while the clamping device disclosed in this embodiment enables rapid installation of the photovoltaic rail 20 and the rail connector 30, the multiple protrusions 221 of the protruding portion 220 can pierce the non-conductive layer on the surface of the photovoltaic rail 20 (a non-conductive oxide film formed on the surface of the aluminum alloy after anodizing), contacting the conductive portion of the photovoltaic rail 20 and achieving electrical connectivity between the two connected photovoltaic rails 20. To ensure that the protruding portion 220 can effectively pierce the non-conductive layer on the surface of the photovoltaic rail 20, the top end area of ​​the spaced-apart protrusions 221 is reduced to increase the contact force between the protrusions 221 and the surface of the photovoltaic rail 20.

[0056] Referring to Figures 2 and 6, in order to achieve the splicing, installation and fixation of two photovoltaic rails 20 on a rail connector 30, the number of the elastic pressing parts 200 of the clamping device disclosed in this embodiment is two, and they are distributed at both ends of the first assembly surface 110 along the extension direction of the photovoltaic rail 20. At the same time, the opening directions of the pressing angles 210 corresponding to the two elastic pressing parts 200 are arranged relative to each other, so that the two photovoltaic rails 20 can slide in from the two ends of the rail connector 30 respectively, and the installation and fixation of the two photovoltaic rails 20 and the rail connector 30 are achieved.

[0057] In order to prevent the photovoltaic track 20 from generating relative displacement along the elastic pressing portion 200 from the first end to the second end after the photovoltaic track 20 and the track connector 30 are assembled, the first assembly surface 110 of the assembly portion 100 also includes a positioning portion 400. One end of the positioning portion 400 is connected to the first assembly surface 110, and the other end extends away from the first assembly surface 110. The positioning portion 400 is located downstream of the elastic pressing portion 200 in the installation direction of the photovoltaic track 20, thereby blocking the movement of the photovoltaic track 20 on the track connector 30.

[0058] Furthermore, referring to Figures 1 and 6 , when two photovoltaic rails 20 are spliced ​​and installed on the same rail connector 30, two positioning portions 400 are provided; these two positioning portions 400 are located between the two elastic pressing portions 200 and are disposed on either side of the first assembly surface 110. These two positioning portions 400 further prevent the two photovoltaic rails 20 from relative displacement within the rail connector 30 and assist in positioning the two photovoltaic rails 20 within the assembly position within the rail connector 30 as they slide into the rail connector 30 for installation, thus preventing any deviation in the relative position of the two photovoltaic rails 20 from the rail connector 30 during assembly.

[0059] Furthermore, the two positioning portions 400 can be located on the same plane, so that after the two photovoltaic rails 20 are spliced ​​and installed, the consistency of the splicing surface and the aesthetics of the assembly are improved, and it can also avoid that after the two photovoltaic rails 20 are spliced, the splicing gap is too large, causing external debris to enter the gap, thereby causing adverse effects on the photovoltaic rails 20 and the rail connector 30.

[0060] The present invention further discloses a photovoltaic track installation structure, comprising a photovoltaic track 20 and a track connector 30 , wherein the photovoltaic track 20 and the track connector 30 are installed and fixed by the above-mentioned clamping device.

[0061] Since the photovoltaic track installation structure has the above-mentioned clamping device, it has all the technical effects of the above-mentioned clamping device, which will not be described in detail herein.

[0062] In order to improve the structural strength and processing efficiency of the card device, the card device is stamped and manufactured in one piece. In addition, in order to ensure that the card device has good performance, the material of the card device is stainless steel / spring steel, or other materials selected by those skilled in the art according to actual needs, which will not be listed here. However, the material of the card device must have elastic deformation and conductive properties to achieve all the technical effects of the card device. Alternatively, those skilled in the art can design the processing and manufacturing method of the card device, or the application of materials according to actual needs, which will not be listed here.

[0063] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
