[0062] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the present application.

They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components or the order or assembly order of the components.
[0064] In known photovoltaic assemblies, a plurality of photovoltaic panels are usually provided. When photovoltaic power generation is required, the plurality of photovoltaic panels are arranged and installed at the target area, and when photovoltaic power generation is not required, the photovoltaic panels can be moved and stored. In order to simplify the arrangement, installation, movement and storage process of photovoltaic panels, in some photovoltaic assemblies, the photovoltaic panels are arranged in a foldable form, especially an accordion-like foldable form. Photovoltaic panels are folded up when not in use, and when photovoltaic panels need to be arranged, a plurality of photovoltaic panels are unfolded and arranged in sequence. However, the folding and unfolding of photovoltaic panels are usually performed manually by installers, which not only requires more manual labor, but also the installation efficiency and installation accuracy of photovoltaic panels are not high.
[0065] The first aspect of the present application provides a guide rail 100 for guiding the folding and unfolding movement of a photovoltaic panel 210 of a foldable photovoltaic assembly. The shaft connected to the photovoltaic panel 210 can move on the guide rail 100 through the moving member 240 thereon, so that the photovoltaic panel 210 can be more easily folded or unfolded in the form of an accordion, thereby reducing the labor consumption when arranging the photovoltaic panel 210 and improving the installation efficiency and installation accuracy of the photovoltaic panel 210.
[0066] In order to describe the structure and function of the guide rail of the present application in more clear and detailed manner, the photovoltaic assembly 1 proposed in the third aspect of the present application and the functions implemented by the guide rail 100 in the photovoltaic assembly 1 are first briefly described below.
[0067] refer to Figure 1 and Figure 2, which respectively show a schematic diagram of a photovoltaic assembly 1 proposed according to an embodiment of the present application and an enlarged view of the photovoltaic assembly 1 at two adjacent photovoltaic panels 210. The photovoltaic assembly 1 proposed in an embodiment of the third aspect of the present application includes a photovoltaic panel assembly 200 and a guide rail 100, and the photovoltaic panel assembly 200 and the guide rail 100 are movably connected to each other. The photovoltaic panel assembly 200 includes a plurality of photovoltaic panels 210, a first shaft rod 220 and a second shaft rod 230, and one side of two adjacent photovoltaic panels 210 is hinged to the first shaft rod 220, and the other side is hinged to the second shaft rod 230. Thus, each photovoltaic panel 210 can rotate around the first shaft rod 220 and the second shaft rod 230, thereby realizing relative folding or unfolding movement between adjacent photovoltaic panels 210. The two ends of the second shaft rod 230 are respectively connected to a moving part 240, and the moving part 240 is arranged on the guide rail 100 and can move along the guide rail 100. From Figure 2 It can be seen that when the moving member 240 moves on the guide rail 100, the straight-line distance between adjacent second shafts 230 also increases or decreases accordingly. At this time, the photovoltaic panel 210 simultaneously rotates around the first shaft 220 and the second shaft 230, thereby realizing the folding and unfolding movement between adjacent photovoltaic panels 210.
[0068] pass Figure 1 and Figure 2 It can be seen that by connecting the moving member 240 on the second shaft 230 of the photovoltaic panel assembly 200 with the guide rail 100, the movement of the two ends of the second shaft 230 on the two guide rails 100 is achieved, thereby achieving the folding and unfolding movement between adjacent photovoltaic panels 210. The first aspect of the present application proposes a guide rail 100 that performs such a function, referring to Figure 3 , which shows a schematic structural diagram of a guide rail 100 according to an embodiment of the present application. The guide rail 100 includes a guide rail body 110, a first track 101 is arranged on the top of the guide rail body 110, and the first track 101 extends along the length direction of the guide rail body 110. A second track 102 is arranged on the side of the guide rail body 110, and the second track 102 extends in the same direction as the first track 101.
[0069] According to the above explanation of the function of the guide rail 100 in the photovoltaic assembly 1, it can be known that the first track 101 of the guide rail 100 is used for the movement of the moving part 240 on the second shaft 230. In addition to the first track 101, the guide rail 100 is also provided with a second track 102 in the same extension direction. The second track 102 is used to combine with the moving parts on other connecting parts or fixing parts in the photovoltaic assembly 1. The moving part 240 in the first track 101 moves synchronously with the moving part in the second track 102 to provide positioning and motion limiting of the moving part 240 of the second shaft 230. The function of the second track 102 in the photovoltaic assembly 1 will be described in detail below when describing the specific structure of the photovoltaic assembly 1.
[0070] In one embodiment of the present application, the guide rail body 110 includes a bearing portion 111 and a notch 112 disposed at the top of the bearing portion 111, and the notch 112 forms the above-mentioned first track 101. The bearing portion 111 of the guide rail body 110 can improve the strength of the guide rail body 110. The assembly formed by the photovoltaic panel 210 moves in the first track 101 as a whole with the moving part 240, so the guide rail body 110 bears a relatively large gravity in the first track 101. The bearing portion 111 is arranged under the first track 101, which is conducive to enhancing the load-bearing capacity of the guide rail 100 and preventing the guide rail 100 from deforming. Further, the bearing portion 111 is arranged as a hollow rectangular frame structure, and the bearing portion 111 is particularly made of aluminum alloy. This further improves the strength of the bearing portion 111 itself.
[0071] In one embodiment of the present application, a rack 113 is provided in the recess 112. In this embodiment, the moving member 240 connected to the second shaft 230 is configured as a gear, which cooperates with the rack 113, and the relative motion between the moving member 240 and the first track 101 is a rolling motion. The rack 113 is connected to the recess 112 by bolts, for example, in which case a through hole for the bolt is provided on the side wall of the recess 112. The rack 113 can also be welded to the recess 112. In some embodiments, when the rack 113 is arranged in the recess 112, a gap is provided between the rack 113 and the side wall of the recess 112, and a foaming member is filled in the gap, and the fixing of the rack 113 in the recess 112 is realized by the foaming member. It should be understood that those skilled in the art can certainly adopt any other fixing method that can fix the rack 113 in the recess 112.
[0072] It should be understood that the rack 113 may not be provided in the recess 112, and the moving member 240 may be provided as a pulley or a slider, etc., which directly rolls or slides along the surface of the recess 112. Those skilled in the art may also adopt any other structural form that can achieve relative motion between the moving member and the first track 101, which should also be included in the protection scope of the present application.
[0073] In one embodiment of the present application, the guide rail 100 further includes a base 120 connected to the bottom of the guide rail body 110 and a wing 130 connected to the side of the guide rail body 110, the base 120 and the wing 130 protrude outward from the guide rail body 110 in a direction perpendicular to the length of the guide rail 100 and the base 120 and the wing 130 also extend in the length direction, and a second track 102 is formed between the base 120 and the wing 130. When installing the photovoltaic assembly 1, the guide rail 100 itself needs to be placed on the installation area or the installation base 300, so the base 120 connected to the bottom of the guide rail body 110 is provided on the guide rail 100 to expand the area of the bottom of the guide rail and increase the fixing stability. When the base 120 is provided, it is only necessary to provide an outwardly protruding side wing 130 on the side of the guide rail body 110 so that a second track 102 is formed between the side wing 130 and the base 120, without having to provide two additional track walls on the side to enclose the second track 102, which further simplifies the structure of the guide rail 100 itself.
[0074] In one embodiment of the present application, a base 120 and a wing 130 (especially a base 120 and a wing 130 of the same structure, which are preferably symmetrical with respect to the guide rail body 110) are respectively arranged on the two sides of the guide rail 100, so that a second track 102 is formed on the two sides of the guide rail 100. This construction method allows connecting members or fixing members connected to the second track 102 to be respectively arranged on the two sides of the guide rail 100, which can simultaneously limit the movement of the moving member 240 and the first track 101. This embodiment will be further explained in detail when describing the specific structure of the photovoltaic assembly 1.
[0075] In one embodiment of the present application, the wing 130 includes a first extension portion 131 connected to the side of the guide rail body 110 and a first stop portion 132 connected to the first extension portion 131. The first stop portion 132 protrudes downward along the height direction of the guide rail body 110 compared to the first extension portion 131. Figure 3As can be seen in the figure, the first extension 131 of the wing 130 forms the upper surface of the second rail 102, and the first stopper 131 can be used to prevent the moving parts in the second rail 102 from escaping from the second rail 102. Furthermore, the thickness of the first extension 131 gradually decreases from the side to the first stopper 132. This arrangement of the first extension 131 is to increase the strength of the wing 130. Since the photovoltaic panel assembly 200 is supported on the first rail 101 by the moving part 240, most of the gravity of the photovoltaic panel assembly 200 is borne by the first rail 101 and the bearing part 111. Therefore, when the moving part moves in the second rail 102, the load applied to the base 120 is generally less than the load applied to the wing 130. Properly increasing the thickness of the wing 130 can prevent the wing 130 from being deformed by the load from the moving part. In order to reduce the overall mass of the guide rail 100 while appropriately increasing the thickness of the side wing 130, the side wing 130 is set to have a thickness that gradually decreases from the side to the first stopper 131. In order to further reduce the weight of the side wing 130, in some embodiments, a weight reduction cavity 133 is provided in the first extension portion 131, especially a weight reduction cavity 133 with a triangular cross section. Such a weight reduction cavity 133 can achieve weight reduction while ensuring that the thickness of the side wing 130 gradually decreases from the side to the first stopper 131, or at least ensure that the thickness of the inner side of the side wing 130 is not less than the thickness of the outer side, so as to minimize or reduce the strength of the side wing 130 to a very small extent.
[0076] In one embodiment of the present application, the base 120 includes a rail portion 121 connected to the bottom of the rail body 110 and a support portion 122 connected to the rail portion 121. The rail portion 121 includes a second extension portion 1211 connected to the bottom and a second stop portion 1212 connected to the second extension portion 1211. The second stop portion 1212 protrudes upward along the height direction of the rail body 110 compared to the second extension portion 1211. The rail portion 121 of the base 120 has a substantially similar structure to that of the side wing 130. The second extension portion 1211 and the first extension portion 131 of the side wing 130 enclose the second rail 102. The second stop portion 1212 is also used to prevent the moving parts from escaping from the second rail 102. A support portion 122 is also provided outside the second stop portion 1212. The support portion 122 can expand the contact area between the bottom of the rail and the fixed area or the base 300, thereby improving the fixing effect of the rail 100. Similar to the side wing 130 , in order to reduce the overall weight of the guide rail 100 , a weight-reducing recess 123 is provided at the bottom of the second extension portion 1211 . The weight-reducing recess 123 is particularly an arched weight-reducing recess 123 .
[0077] In one embodiment of the present application, the guide rail body 110, the base 120 and the side wing 130 are integrally formed and are all made of aluminum alloy, which is conducive to simplifying the manufacture of the entire guide rail and also improves the strength of the entire guide rail. It should be understood that those skilled in the art can use other methods or materials to manufacture the guide rail 100 while meeting the functions of the guide rail 100 according to the requirements of different photovoltaic assemblies, and this should also be included in the scope of protection of the present application.
[0078] In one embodiment of the present application, a mounting hole 1221 is provided on the support portion 122 of the guide rail base 120 for mounting on the base 300 of the photovoltaic assembly 1. At this time, the guide rail 100 is not used to be placed directly on the ground, but is connected to the base 300 arranged on the ground through the mounting hole 1221, especially bolts. The base 300 is especially configured as a hollow square tube arranged perpendicular to the length direction of the guide rail 100, and a matching mounting hole is provided thereon. The setting of the base 300 makes the guide rail 100 have a certain distance from the ground, which is conducive to preventing the external environmental factors from corroding the guide rail 100, especially preventing it from interfering with the movement in the first rail 101 and the second rail 102, for example, preventing water, dust, etc. from entering the first rail 101 and the second rail 102 to interfere with the movement of the above-mentioned moving parts 240 and moving components.
[0079] In one embodiment of the present application, two groups of mounting holes 1221 are provided on the support portion 122, each group of mounting holes includes a plurality of evenly spaced mounting holes 1221, and the two groups of mounting holes are symmetrical to each other about the center of the guide rail. This arrangement of mounting holes 1221 is advantageous in the case where a plurality of guide rails 100 are required to be assembled into a guide rail assembly 10 of a photovoltaic assembly 1, and can be particularly matched to the case where a different number of bases 300 are used. For example, different numbers of bases or bases with different spacings from each other can be provided according to terrain and environmental reasons, and the arrangement of a plurality of mounting holes 1221 allows the guide rail 100 to be flexibly matched to different numbers of bases 300 or bases with different spacings from each other. The symmetrical design of the two groups of mounting holes 1221 about the center of the guide rail makes it unnecessary to consider the left and right orientations of the two ends of the guide rail 100 during installation, which is beneficial to improving the installation efficiency of the guide rail 100.
[0080] A second aspect of the present application provides a guide rail assembly 10. Figure 4 , which shows a schematic diagram of the connection between two guide rails 100 in a guide rail assembly 10 according to an embodiment of the present application. The guide rail assembly 10 includes a plurality of the above-mentioned guide rails 100 and a fixed connection member 11. Figure 4In the embodiment, the fixed connection member 11 is configured as an angle steel, for example. First through holes 114 are provided at both ends of the guide rail body 110 of each guide rail 100, and corresponding through holes are also provided at both ends of the fixed connection member 11, so that both ends of the fixed connection member 11 can be connected to the first through holes 114 of adjacent ends of two adjacent guide rails 100 by bolts 12, respectively, to fix and connect the two adjacent guide rails 100.
[0081] Since the photovoltaic assembly 1 usually has multiple photovoltaic panels 210 and the size of the photovoltaic panels 210 is relatively large, the overall track length used for unfolding the photovoltaic panels 210 is usually also relatively long. If the guide rail of the photovoltaic assembly 1 is set as a whole in the form of a guide rail assembly 10 formed by installing multiple guide rails 100, each guide rail 100 can be set to a shorter length, which is convenient for the manufacture, movement and installation of the guide rail 100. In addition, the guide rail 100 can also be set in the form of a standard part so that it can be suitable for photovoltaic assemblies 1 with different numbers of photovoltaic panels 210, thereby achieving more flexible application of a single guide rail 100.
[0082] In one embodiment of the present application, the guide rail assembly 10 further includes a connecting pipe 13. Figure 5 , which shows that according to Figure 4 The enlarged view of the connection of two mutually connected guide rails 100 with one of the guide rails removed. A second through hole is respectively provided at both ends of the connecting pipe 13, and the two ends of the connecting pipe 13 are respectively inserted into the bearing parts 111 of the two adjacent guide rails 100 so that the two second through holes are respectively matched with the positions of the first through holes 114 of the two adjacent guide rails 100, and the connecting pipe 13 is respectively connected to the two adjacent guide rails 100 and the fixed connecting member 11 by the bolts 12. The connecting pipe 13 is particularly configured to be installed in the bearing part 111 in a shape matching with the hollow structure bearing part 111.
[0083] The moving part 240 will move through each position of the guide rail assembly 10, so that the load caused by the gravity of the photovoltaic panel 210 is applied to each position of the guide rail 100 during the movement. Since the guide rail assembly 10 is formed by connecting multiple guide rails 100, the load-bearing capacity at the connection between two adjacent guide rails 100 is generally weaker than other parts of the guide rail assembly 10. By adding the connecting pipe 13, the connection between two adjacent guide rails 100 can be additionally loaded through the connecting pipe 13 arranged in the load-bearing part 111, thereby improving the strength of the guide rail assembly 10, especially the strength at the connection between two adjacent guide rails 100, so that the gravity of the photovoltaic assembly 1 will not cause the adjacent guide rails 100 to deform or deviate at the connection, thereby affecting the movement of the moving part 240 on the guide rail 100.
[0084] The third aspect of the present application provides a photovoltaic assembly 1. The structure of the photovoltaic assembly 1 in one embodiment of the present application can be referred to again. Figure 1 and 2 The photovoltaic assembly 1 includes a photovoltaic panel assembly 200 and the above-mentioned guide rail 100 or guide rail assembly 10, especially two guide rails 100 or two guide rail assemblies 10 arranged in parallel. The photovoltaic panel assembly 200 includes a plurality of photovoltaic panels 210, a first shaft 220 and a second shaft 230, one side of two adjacent photovoltaic panels 210 is hinged to the first shaft 220 through a first hinge 211, and the other side of two adjacent photovoltaic panels 210 is hinged to the second shaft 230 through a second hinge 212, and both ends of the second shaft 230 are respectively connected to moving parts 240, and the two moving parts 240 are respectively arranged on the two guide rails 100 or guide rail assemblies 10, especially in the first track 101 thereof.
[0085] refer to Figure 2 , photovoltaic panels 210 in Figure 2 In the embodiment, for example, the photovoltaic panels 210 are first connected to two parallel support rods 270, and then hinged to the first shaft rod 220 arranged perpendicularly to the support rod 270 through the first hinges 211 respectively connected to one end of the two support rods 270, and hinged to the second shaft rod 230 arranged perpendicularly to the support rod 270 through the second hinges 212 respectively connected to the other ends of the two support rods 270. The first shaft rod 220 only plays the role of connection and rotation, and is not connected to the guide rail 100 or the guide rail assembly 10. The plurality of photovoltaic panels 210 realize the folding and unfolding movement around the first shaft rod 220 and the second shaft rod 230 through the movement of the moving member 240 along the first track 101.
[0086] exist Figure 2 In the embodiment, the first hinge 211 includes two hinges, which may be identical or different in structure, and the second hinge 212 also includes two hinges, which may be identical or different in structure. It is understood by those skilled in the art that, when the hinges can realize the connection and relative rotation between the photovoltaic panel 210 or the support rod 270 and the shaft rods 220 and 230, any hinges with different structures and different numbers can be selected to realize the connection between the photovoltaic panel 210 or the support rod 270 and the shaft rods 220 and 230, which should be included in the scope of the present application.
[0087] It should be understood that, in addition to Figure 2In the embodiment, the photovoltaic panel 210 can also be connected to the first shaft 220 and the second shaft 230 in other ways, for example, directly connected to the first shaft 220 and the second shaft 230 at its edge through a hinge, using other intermediate elements (such as the above-mentioned support rod 270) to first connect with the hinge, and then connected to the first shaft 220 and the second shaft 230 through the hinge. These connection methods should all be included in the protection scope of the present application.
[0088] In one embodiment of the present application, a rack 113 is provided in the first track 101, and the moving member 240 is provided as a gear matched with the rack 113. Figure 6 , which shows a schematic structural diagram of the guide rail 100 from one side when the photovoltaic panel assembly 1 is installed on the guide rail 100 according to an embodiment of the present application. In this embodiment, in order to improve the movement flexibility of the moving part 240 in the first track 101, a rack 113 is provided in the first track 101, and the moving part 240 is configured as a gear that cooperates with the rack 113. The rolling movement of the gear on the rack 113 drives the second shaft 230 to move linearly along the length direction of the first track 101. Furthermore, the gear and the second shaft 230 are connected by the bearing 241 (in the Figure 8 In other words, the gear and the second shaft 230 can rotate relative to each other. Therefore, when the gear rolls on the rack 113, the second shaft 230 itself does not need to rotate, but only needs to make a linear motion along the length direction of the first track 101. This further improves the movement flexibility of the moving member 240.
[0089] It should be understood that the motion cooperation between the first track 101 and the moving member 240 can also be set in other forms. For example, the moving member 240 can be set as a slider, which can slide in the first track 101, and in this case, the rack 113 does not need to be set in the first track 101. The first track 101 and the moving member 240 can also adopt a cooperation form such as belt drive or chain drive. Those skilled in the art can change the structural form of the moving member 240 and / or the first track 101 according to different cooperation forms, which should also be included in the protection scope of this application.
[0090] In one embodiment of the present application, the photovoltaic panel assembly 1 also includes a fixing member 250 connected to the guide rail 100 and a motor (not shown in the figure) fixed to the fixing member 250. The main body of the fixing member 250 is configured in a plate shape, and the motor is fixed to the fixing member 250 through the motor mounting hole 255 on the fixing member 250. The output shaft of the motor is connected to the gear shaft of the gear through the through hole 256 on the fixing member 250, so that the motor can provide power for the rotation of the gear on the rack 113. In this way, the rolling of the gear on the rack 113 can be automatically carried out by the power provided by the motor, without the need for the installer to manually drive the gear to roll. It can be understood by those skilled in the art that in addition to the motor, other power sources can also be used to achieve automatic driving of the gear.
[0091] In one embodiment of the present application, the fixing member 250 not only serves to fix the motor, but also serves to limit the movement of the gear. The fixing member 250 is provided with a clamping shaft 251 extending into the second track 102, and the clamping shaft 251 is provided with a first rolling member 252, and the first rolling member 252 can roll along the second track 102. When the gear rolls on the rack 113, the first rolling member 252 rolls synchronously in the second track 102, so that the fixing member 250 is always kept in a position relative to the gear, and the movement path of the gear is limited to the rack 113, so as to prevent the gear from deviating from the rack 113 when moving. The first stopper 131 and the second stopper 1212 respectively provided on the wing 130 and the base 120 enable the first rolling member 252 to always remain in the second track 102 when moving, and further enable the fixing member 250 to remain in the same relative position with the gear, so that the gear is always kept at the same position in its axial direction.
[0092] In one embodiment of the present application, the first rolling member 252 includes a ball bearing 253 and a rolling bearing 254 arranged in sequence along the axial direction of the clamping shaft 251, the ball bearing 253 rolls along the side of the guide rail body 110 in the second track 102, and the rolling bearing 254 rolls along the surface of the flank 130 and the base 120 in the second track 102. Among them, the ball bearing 253 always rolls on the side of the guide rail body 110, thereby ensuring the positioning of the fixing member 250 in the longitudinal direction perpendicular to the guide rail 100, that is, the axial direction of the second shaft 230 or the gear, and the rolling bearing 254 always rolls along the surface of the flank 130 and the base 120, thereby ensuring the positioning of the fixing member 250 in the height direction of the guide rail 100. By ensuring the positioning of the fixing member 250 in these two directions, the positioning of the gear in its axial direction and the height direction of the guide rail 100 is further limited, so that the gear can always keep the position accurately rolling on the rack 113 without causing the deviation of the motion trajectory.
[0093] refer to Figure 7 , which shows that according to Figure 6 An enlarged view of the fixing member 250. Figure 7 In the embodiment, the number of the clamping shafts 251 is two, which are arranged at intervals along the length direction of the guide rail 100. A ball bearing 253 and a rolling bearing 254 are provided on each clamping shaft 251. This further increases the movement stability of the fixing member 250, thereby better limiting the position of the gear in its axial direction. It should be understood that the number of the clamping shafts 251 can also be 1 or more than 2, and a single clamping shaft 251 can be provided with only a ball bearing 253, only a rolling bearing 254, or more than one rolling bearing 254. As long as it is ensured that all the clamping shafts 251 include at least one ball bearing 253 and at least one rolling bearing 254 in total, these embodiments of the clamping shafts 251 and the ball bearings 253 and rolling bearings 254 thereon should be included in the protection scope of the present application.
[0094] In one embodiment of the present application, the second shaft rod 230 and the guide rail 100 are further connected via a connecting rod 260. Figure 8, which shows a schematic structural diagram of the guide rail 100 from the other side when the photovoltaic panel assembly 1 is installed on the guide rail 100 according to an embodiment of the present application. In this embodiment, the connecting rod 260 is configured as an L-shaped connecting rod 260, one end 261 of which is connected to the second shaft rod 230, and the other end 262 extends into the second track 102 of the guide rail 100 away from the fixing member 250 and is connected to a second rolling member 263, which can roll in the second track 102. The movement of the second rolling member 263 is similar to that of the first rolling member 252, and it also rolls in the second track 102 synchronously with the movement of the gear on the rack 113. Since one end 262 of the connecting rod 260 is connected to the second rolling element 263, and one end 261 is connected to the second shaft 230, it is independent of the fixing element 250 and directly increases the connection strength between the second shaft 230 and the guide rail 100, and further realizes the movement limit of the gear on the rack 113 on the inner side of the guide rail 100, on the one hand, preventing the second shaft 230 from being disengaged and offset during the movement, especially when there is a large wind force in the surrounding environment, and on the other hand, further preventing the gear from moving away from or disengaging from the rack 113. Further, the second rolling element 263 is configured as a joint bearing, so that the connecting rod 260 has more degrees of freedom at the second rolling element 263, and it can be freely offset in all directions, so that when the second rolling element 263 is always connected to the second track 102, the L-shaped connecting rod 260 does not need to be always in a vertical position, and can have a certain inclination, which leaves a certain movement space for the L-shaped connecting rod 260, and prevents the connecting rod 260 from being deformed due to excessive load when the external wind force is too large.
[0095] In one embodiment of the present application, a thread is provided on the end 261 of the connecting rod 260 connected to the second shaft 263, a threaded hole is provided on the second shaft 230, the connecting rod 260 is screwed onto the second shaft 230 by the thread and protrudes beyond the second shaft 230, and a first wiring board 400 is installed on the portion of the connecting rod 260 protruding beyond the second shaft 230, and the first wiring board 400 is especially installed to the end 261 of the connecting rod 260 provided with the thread through the through hole and the nut thereon. A second wiring board 500 opposite to the first wiring board 400 is installed on the fixing member 250. The first wiring board 400 and the second wiring board 500 especially respectively include vertical plates 410, 510 and horizontal plates 420, 520 connected at right angles to each other, the vertical plates 410, 510 are arranged along the height direction of the guide rail 100, and the horizontal plates 420, 520 are preferably higher than the gear in the height direction of the guide rail 100. For example, wiring holes 421, 521 through which wires can pass are provided on the horizontal plates 420, 520 of the first wiring board 400 and the second wiring board 500. Through the arrangement of the first wiring board 400 and the second wiring board 500, the wiring harness of the photovoltaic panel 210 and the motor can be arranged better over the gear and the rack 113, preventing the wiring harness from being rolled into the gear or the rack 113 or being wound around the second shaft 230 when the gear rolls on the rack 113.
[0096] The fourth aspect of the present application also provides a method for arranging the photovoltaic assembly 1. Fig. 9 , which shows a flow chart of a method for arranging a photovoltaic assembly 1 according to an embodiment of the present application, wherein S100-S400 represent each step of the method respectively. The method comprises the following steps:
[0097] S100: Connecting the guide rail 100 to form a guide rail assembly 10 by connecting the connecting pipe 13 and the fixed connecting member 11;
[0098] S200: Install the guide rail assembly 10 onto the base 120 through the mounting hole 1221 provided thereon;
[0099] S300: Install the moving member 240 and the L-shaped connecting rod 260 onto the second shaft 230;
[0100] S400 : Install the moving member 240 on the first track 101 , and install the second rolling member 263 on one end of the connecting rod 260 on the second track 102 .
[0101] In this embodiment, the guide rail assembly 10 is first assembled, and in order to avoid interference from external environmental factors such as dust, rain, etc. when the guide rail assembly 10 is directly placed on the ground, the guide rail assembly 10 is installed on the base 300, and the base 300 is placed on the ground instead of the guide rail assembly 10. The guide rail 100 is connected to the base 300 by bolts, for example.
[0102] The second shaft 230 is connected to the guide rail 100 after being assembled with the moving member 240 and the connecting rod 260. Since the movement of the moving member 240 and the second rolling member 263 on the guide rail 100 is substantially synchronous, the moving member 240 can be installed on the first track 101 and the second rolling member 263 can be installed on the second track 102 at the same time during installation to improve the efficiency of installation.
[0103] In one embodiment of the present application, the above method further includes the following steps:
[0104] Install the first rolling member 252 on the fixing member 250 onto another second track 102;
[0105] The motor is mounted on the fixing member 250 , and the output shaft of the motor is drivingly connected to the moving member 240 .
[0106] The fixing member 250 is installed after the second shaft 230 and the gear are installed so as to be aligned with the gear shaft. When installing the fixing member 250, first install the first rolling member 252 on another second track 102, that is, the second track 102 without the second rolling member 263 installed, and move the fixing member 250 into position through the rolling motion of the first rolling member 252 in the second track 102, especially aligning the through hole 256 on the fixing member 250 with the gear shaft. Finally, install the motor, and drive the output shaft of the motor to the moving member 240.
[0107] In summary, the guide rail 100, guide rail assembly 10 and photovoltaic assembly 1 proposed in one embodiment of the present application can provide a foldable photovoltaic panel with a folding and unfolding movement mode that is easy to install, smooth in movement and high in movement precision, so that the folding and unfolding of the photovoltaic panel is smoother, and the moving part 240 is not easy to deviate or fall off the track. It can also increase the connection strength between the shaft rod of the photovoltaic panel 210 and the guide rail 100, thereby achieving stable fixation of the photovoltaic panel 210 during arrangement and installation.
[0108] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the legal protection scope of the present application.
