Description

Technical Field

[0001] This invention relates to the field of photovoltaic mounting technology, and in particular to a foldable photovoltaic mounting bracket. Background Technology

[0002] Photovoltaic (PV) mounting systems are structural components used to support photovoltaic (PV) modules in solar power generation systems, playing a crucial role. Once installed, the mounting system's angle remains fixed. Typically, an optimal tilt angle is chosen based on local latitude and solar radiation conditions to ensure the PV modules receive relatively stable solar radiation throughout the year.

[0003] The existing technology still has the following problems: the photovoltaic brackets on the market are all spliced ​​together. If a temporary power supply project needs to be deployed quickly, the photovoltaic brackets assembled by this method cannot be quickly spliced ​​and disassembled, which has certain limitations. Secondly, the specifications of the photovoltaic brackets are fixed, and it is impossible to customize the best photovoltaic panel support system according to the temporary power supply project to be deployed quickly, thus failing to meet the current needs. Summary of the Invention

[0012] Optionally, the folding mechanism includes a linkage component and a second driven gear. A stabilizing side plate is fixedly installed at one end of one side of the support plate. The linkage component is located on one side of the stabilizing side plate, and a seventh bevel gear transmission mechanism that is connected to the second driven gear is located on the other side of the stabilizing side plate. Both sets of positioning plates are rotated relative to each other on the support plate through the linkage component.

[0013] Optionally, the linkage component includes a fixed base and a fourth synchronization mechanism. The fixed base is fixedly installed on the other end of one side of the support plate. Both ends of the upper surface of the fixed base are fixedly installed with bearing shells. Rotary gears are fixedly installed on the ends of the two sets of positioning plates that are close to each other, and the two sets of rotating gears are meshed with each other. The positioning plates are rotatably installed on one side of the bearing shells. A third synchronization mechanism is provided on the other side of one set of bearing shells. One end of the third synchronization mechanism is drivenly connected to one set of rotating gears. The other end of the third synchronization mechanism is drivenly connected to a sixth bevel gear transmission mechanism. The fourth synchronization mechanism is drivenly installed between the sixth bevel gear transmission mechanism and the seventh bevel gear transmission mechanism.

[0014] Optionally, the support mechanism further includes two sets of extension components, and the positioning plate is composed of a first positioning rod and a second positioning rod. The first positioning rod is slidably sleeved on the outside of the second positioning rod. The rotating gear is fixedly installed on one end of the first positioning rod, and the first positioning rod is rotatably connected to the bearing shell. The extension components are disposed on one side of the first positioning rod.

[0015] Optionally, the extension assembly includes a positioning shell, a drive gear, and a fixed shell. The positioning shell is fixedly installed on one side of the first positioning rod, the drive gear is fixedly installed on one side of the positioning shell, the fixed shell is disposed on one side of the support plate, and the fixed shell is slidably installed on the outside of the positioning shell. A linkage gear that meshes with the drive gear is rotatably installed on one side of the fixed shell. A second synchronization mechanism is provided between the fixed shell and the positioning shell.

[0016] Optionally, a gear transmission mechanism is provided inside the positioning shell, and the gear transmission mechanism is connected to the second synchronization mechanism.

[0018] According to one embodiment of this disclosure, through the design of the bracket mechanism, four sets of support plates can be quickly unfolded by the first flipping component to form a bracket prototype, and multiple sets of positioning plates can be unfolded to a horizontal state by the second flipping component to complete the installation of the bracket. Thus, there is no need for workers to repeatedly install and disassemble bolts. Therefore, through the drive mechanism and the interconnected bracket mechanism, the photovoltaic bracket can be quickly assembled for use, effectively improving the installation and dismantling efficiency.

[0019] Meanwhile, during the unfolding process of the positioning plate, the extension components extend the length of the two sets of carrier plates that rotate relative to each other. The two sets of carrier plates can be manually unfolded so that the carrier plates and positioning plates form a tripod, which can more stably support the photovoltaic panels.

[0020] By using a design where the positioning plate consists of a first positioning rod and a second positioning rod, and the bearing plate consists of a first bearing rod and a second bearing rod, the area of ​​the photovoltaic bracket can be adjusted.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention enables the bracket to be opened and closed by rotation through the cooperation of the drive mechanism, the support mechanism and the folding mechanism. Moreover, the photovoltaic bracket can be opened and closed by the operator only needs to control the forward and reverse drive of the servo motor and control the position of the servo motor. Therefore, it is more convenient and more practical than the traditional assembled bracket.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 16As shown, a foldable photovoltaic mounting bracket includes a support column 3 and a rotating base 5. The rotating base 5 is rotatably mounted on the upper end of the support column 3 and is detachably mounted on the upper end of the support column 3 by bolts. It also includes:

[0043] The support mechanism 1 consists of four sets of support plates 103, and two sets of positioning plates 102 are symmetrically and rotatably connected to the ends of the four sets of support plates 103. A bearing plate 101 is provided on the same side of the two sets of positioning plates 102.

[0044] Drive mechanism 2 is mounted on rotating seat 5, and support plate 103 is rotatably mounted on rotating seat 5 via drive mechanism 2;

[0045] like Figures 1 to 15 As shown, because the support plate 103 is designed to rotate with the rotating seat 5 through the drive mechanism 2, multiple sets of support plates 103 can be flipped at the same time, thereby quickly forming a bracket prototype and further improving the installation efficiency of the photovoltaic bracket.

[0046] The folding mechanism 4 is provided in multiple sets and is mounted on the support plate 103. The folding mechanism 4 is connected to the drive mechanism 2, and both sets of positioning plates 102 are rotatably mounted on the support plate 103 through the folding mechanism 4.

[0047] like Figures 1 to 15 As shown, because the positioning plates 102 are all rotated with the support plates 103 through the folding mechanism 4, when the support plates 103 are flipped to form the bracket prototype, the positioning plates 102 can be flipped relative to each other through the folding mechanism 4, so that the two sets of positioning plates 102 are unfolded, and the positioning plates 102 and the support plates 103 are combined to form a rectangle, which is sufficient to support the photovoltaic system for installation.

[0048] Furthermore, the drive mechanism 2 includes a first flipping component 203, a second flipping component 204, and a servo motor 202. The servo motor 202 is used to drive the first flipping component 203 and the second flipping component 204. Both the first flipping component 203 and the second flipping component 204 are mounted on the rotating seat 5. The first flipping component 203 is used to drive the support plate 103 to rotate. The second flipping component 204 is connected to the unfolding mechanism 4 in a transmission manner.

[0049] The first flipping assembly 203 includes a first transmission gear 2033 and multiple sets of first driven gears 2034. Multiple sets of flipping seats 402 are arranged around the upper surface of the rotating seat 5. A flipping plate 403 is rotatably connected to the support plate 103 and is fixedly connected to the support plate 103. The first transmission gear 2033 is rotatably installed inside the rotating seat 5. Multiple sets of first driven gears 2034 are meshed with the outer side of the first transmission gear 2033. A fifth bevel gear transmission mechanism 401 is provided inside the flipping seat 402 and is rotatably connected to the first driven gear 2034. The flipping plate 403 is rotatably mounted on the support plate 103 through the fifth bevel gear transmission mechanism 401. The first transmission gear 2033 is rotatably installed inside the rotating seat 5 through the servo motor 202.

[0050] like Figures 1 to 15 As shown, through the design of the transmission connection between the first driven gear 2034 and the first transmission gear 2033, the first transmission gear 2033 can simultaneously drive multiple sets of first driven gears 2034 to rotate. Thus, the first driven gear 2034 controls the flipping plate 403 to drive the support plate 103 to rotate through the fifth bevel gear transmission mechanism 401, thereby realizing the simultaneous flipping and unfolding of multiple sets of support plates 103 to form a bracket prototype.

[0051] Furthermore, the second flipping assembly 204 includes a second transmission gear 2044, which is rotatably mounted on the middle of the upper surface of the rotating base 5 via a servo motor 202, and the unfolding mechanism 4 is connected to the second transmission gear 2044 in a transmission connection.

[0052] Specifically, such as Figures 1 to 5As shown, a recessed groove is provided on the outer side of the rotating seat 5, and a damping groove is provided at one end of the recessed groove. A damping push rod 201 is slidably installed inside the damping groove. One end of the damping push rod 201 is slidably installed inside the recessed groove and is fixedly connected to a servo motor 202. The servo motor 202 is slidably installed inside the recessed groove. A linkage rod 205 is fixedly installed at one end of the output shaft of the servo motor 202. A transmission groove is provided at the other end of the recessed groove. A second bevel gear transmission mechanism 2031 is provided inside the transmission groove. The second bevel gear transmission mechanism 2031 consists of two sets of meshing bevel gears. Multiple sets of protrusions are provided at one end of the outer circumference of the linkage rod 205, and one set of bevel gears is slidably sleeved on the outer side of the linkage rod 205. Furthermore, the linkage rod 205 is engaged with one of the sets of bevel gears via a protrusion. A stabilizing rod 2041 is provided inside the transmission groove, and a fourth bevel gear transmission mechanism 2042 composed of two sets of meshing bevel teeth is provided inside the transmission groove via the stabilizing rod 2041. A slot is opened in the middle of one side of one set of bevel teeth, and the linkage rod 205 is engaged with the slot via a protrusion. The end of the second bevel gear transmission mechanism 2031 is connected to a housing 2035, and the housing 2035 is fixedly connected to the first transmission gear 2033. The end of the fourth bevel gear transmission mechanism 2042 is fixedly installed with a transmission rod 2043, and the housing 2035 is rotatably sleeved on the outside of the transmission rod 2043. The transmission rod 2043 is fixedly connected to the second transmission gear 2044.

[0053] Through the design of the damping push rod 201, the second bevel gear transmission mechanism 2031, the fourth bevel gear transmission mechanism 2042 and the linkage rod 205, the servo motor 202 can drive the second bevel gear transmission mechanism 2031 and the fourth bevel gear transmission mechanism 2042 separately by sliding to different positions. Thus, the servo motor 202 can drive the first transmission gear 2033 and the second transmission gear 2044 respectively, further differentiating and controlling the rotation support plate 103 and the rotation positioning plate 102.

[0054] It should be noted that the servo motor 202 is slidably mounted inside the groove, which can prevent the servo motor 202 from rotating itself when it drives the target structure to rotate.

[0055] Meanwhile, the use of damping push rod 201 can quickly adjust the position of servo motor 202, and can also prevent servo motor 202 from automatically displacing, which would prevent it from driving the target structure.

[0056] Furthermore, the folding mechanism 4 includes a linkage component 404 and a second driven gear 407. A stabilizing side plate 405 is fixedly installed on one end of the support plate 103. The linkage component 404 is disposed on one side of the stabilizing side plate 405, and a seventh bevel gear transmission mechanism 406 that is connected to the second driven gear 407 is disposed on the other side of the stabilizing side plate 405. Both sets of positioning plates 102 are rotatably disposed on the support plate 103 through the linkage component 404.

[0057] like Figures 1 to 15 As shown, by setting the second driven gear 407, when the support plate 103 is flipped to the optimal angle, the second driven gear 407 will fit against the upper surface of the rotating seat 5 and enter the position of meshing with the second transmission gear 2044. At this time, the second transmission gear 2044 can be rotated by the servo motor 202, so that the second driven gear 407 controls the linkage component 404 to drive through the seventh bevel gear transmission mechanism 406, so that the linkage component 404 controls the positioning plate 102 to flip to the horizontal state, and completes the unfolding and use of the bracket.

[0058] It is worth noting that the present invention only requires the staff to adjust the position of the servo motor 202, and then the photovoltaic bracket can be automatically unfolded and used through the power drive of the servo motor 202. Therefore, this method not only eliminates the need for staff to manually install and assemble the bracket, but also allows the entire bracket to be folded and retracted for carrying.

[0059] Furthermore, the linkage component 404 includes a fixed base 4048 and a fourth synchronization mechanism 4045. The fixed base 4048 is fixedly installed on the other end of one side of the support plate 103. Both ends of the upper surface of the fixed base 4048 are fixedly installed with bearing shells 4041. Rotary gears 105 are fixedly installed on the ends of the two sets of positioning plates 102 that are close to each other, and the two sets of rotating gears 105 are meshed with each other. The positioning plates 102 are rotatably installed on one side of the bearing shells 4041. A third synchronization mechanism 4044 is provided on the other side of one set of bearing shells 4041. One end of the third synchronization mechanism 4044 is connected to one set of rotating gears 105. The other end of the third synchronization mechanism 4044 is connected to a sixth bevel gear transmission mechanism 4047. The fourth synchronization mechanism 4045 is installed between the sixth bevel gear transmission mechanism 4047 and the seventh bevel gear transmission mechanism 406.

[0060] Specifically, such as Figures 1 to 15 As shown, both ends of the bottom of the fixed base 4048 are fixedly installed with connecting bases 4042, and the connecting bases 4042 are fixedly connected to the support plate 103. One set of connecting bases 4042 is fixedly installed with a protective shell 4043 on one side. The sixth bevel gear transmission mechanism 4047 is located inside the protective shell 4043. The end of the fourth synchronization mechanism 4045 is located inside the connection between the protective shell 4043 and the connecting base 4042.

[0061] Specifically, the third synchronization mechanism 4044 mentioned above has a drive rod 4046 fixedly installed at its end, and the drive rod 4046 passes through the bearing shell 4041 and is fixedly connected to one of the sets of rotating gears 105.

[0062] Through the design of the connecting seat 4042 and the protective shell 4043, the symmetrical design of the connecting seat 4042 makes the connection between the fixed seat 4048 and the support plate 103 more stable. Secondly, the protective shell 4043 can protect the sixth bevel gear transmission mechanism 4047 and the third synchronization mechanism 4044, so as to prevent the structure from being exposed and affecting normal use.

[0063] like Figures 1 to 15 As shown, through the design of two sets of rotating gears 105 meshing with each other, when the second transmission gear 2044 drives the fourth synchronization mechanism 4045 through the second driven gear 407 and the seventh bevel gear transmission mechanism 406, the fourth synchronization mechanism 4045 controls the drive rod 4046 to rotate through the sixth bevel gear transmission mechanism 4047 and the third synchronization mechanism 4044, so that the two sets of rotating gears 105 rotate relative to each other, thereby realizing the relative flipping and unfolding of the two sets of combined positioning plates 102, so that the bracket is fully unfolded, which is convenient for the installation and use of photovoltaic panels.

[0064] Specifically, the support plate 103 mentioned above is composed of an arc plate 1031, a deformation plate 1032, and a deformation spring 1033. The arc plate 1031 is fixedly connected to the flip plate 403 and the connecting seat 4042. A deformation groove is provided on the inner side of the arc plate 1031. The deformation spring 1033 is disposed inside the deformation groove. The deformation plate 1032 is fixedly installed around the inner side of the arc plate 1031. The deformation spring 1033 is fixedly connected to the deformation plate 1032.

[0065] For example, the deformation plate 1032 mentioned above can be made of flexible steel plate material. When the arc plate 1031 is flipped and unfolded, the deformation plate 1032 is elastically squeezed by the deformation spring 1033, so that the arc angle of the deformation plate 1032 changes to the opposite, and the overall shape of the support plate 103 is transformed into a flat arc state. This state can better reduce wind resistance and make photovoltaic use more stable.

[0066] Furthermore, the support mechanism 1 also includes two sets of extension components 104, and the positioning plate 102 is composed of a first positioning rod 1021 and a second positioning rod 1022. The first positioning rod 1021 is slidably sleeved on the outside of the second positioning rod 1022, the rotating gear 105 is fixedly installed on one end of the first positioning rod 1021, and the first positioning rod 1021 is rotatably connected to the bearing shell 4041. The extension component 104 is disposed on one side of the first positioning rod 1021.

[0067] like Figures 1 to 15As shown, the positioning plate 102 is designed to consist of a first positioning rod 1021 and a second positioning rod 1022. The overall length of the positioning plate 102 can be changed by the first positioning rod 1021 and the second positioning rod 1022. Therefore, the length of the positioning plate 102 can be adjusted according to the working scenario and usage, thereby further improving the practicality of the photovoltaic mounting bracket.

[0068] Furthermore, the extension assembly 104 includes a positioning shell 1041, a drive gear 1042, and a fixed shell 1046. The positioning shell 1041 is fixedly installed on one side of the first positioning rod 1021, the drive gear 1042 is fixedly installed on one side of the positioning shell 1041, and the fixed shell 1046 is movably installed on one side of the support plate 103, and the fixed shell 1046 is slidably installed on the outside of the positioning shell 1041. A linkage gear 1043 that meshes with the drive gear 1042 is rotatably installed on one side of the fixed shell 1046. The fixed shell 1046 and the positioning shell 1041... A second synchronization mechanism 1044 is provided between 41, and the linkage gear 1043 is connected to the second synchronization mechanism 1044. A stabilizing plate 1048 is rotatably connected between the linkage gear 1043 and the drive gear 1042 on the same side. A gear transmission mechanism 9 is provided inside the positioning shell 1041, and the gear transmission mechanism 9 is connected to the second synchronization mechanism 1044. A telescopic screw 1047 is rotatably connected to the outside of the positioning shell 1041 through the gear transmission mechanism 9, and one end of the second positioning rod 1022 is threaded onto the outside of the telescopic screw 1047.

[0069] like Figures 1 to 15 As shown, through the design of the drive gear 1042 and the linkage gear 1043, when the rotating gear 105 drives the positioning plate 102 to rotate as a whole, the positioning plate 102 drives the drive gear 1042 to rotate. The linkage gear 1043 in the fixed position will rotate through the rotating drive gear 1042. The linkage gear 1043, through the second synchronization mechanism 1044, causes the first bevel gear transmission mechanism 1045 to control the telescopic screw 1047 to rotate through the gear speed change mechanism 9. Thus, the telescopic screw 1047 drives the second positioning rod 1022 to extend, so that the length of the positioning plate 102 can be automatically extended.

[0070] Specifically, such as Figure 13As shown, the gear transmission mechanism 9 described above consists of multiple sets of driving transmission gears 901 and multiple sets of driven transmission gears 902, and the driving transmission gears 901 and driven transmission gears 902 are staggered. A square pull rod 7 is installed in the middle of the multiple sets of driven transmission gears 902. A transmission groove is opened at one end of the positioning housing 1041, and a first synchronization mechanism 8 is provided at one end of the transmission groove. The end of the first synchronization mechanism 8 is slidably sleeved on the outside of the square pull rod 7. The telescopic screw 1047 is connected to the first synchronization mechanism 8. The multiple sets of driving transmission gears 901 are fixedly arranged with each other, and one set of driving transmission gears 901 is connected to the first bevel gear transmission mechanism 1045.

[0071] Through the design of the gear transmission mechanism 9, during the rotation of the positioning plate 102, the first bevel gear transmission mechanism 1045 can drive the pre-adjusted gear transmission mechanism 9 to rotate, so that the rotation speed of the telescopic screw 1047 is different, thereby achieving different extension lengths of the second positioning rod 1022. Therefore, the photovoltaic mounting bracket can be adjusted to the optimal photovoltaic support area according to different usage scenarios, further improving the practicality of the photovoltaic mounting bracket.

[0072] Furthermore, the support plate 101 is composed of a first support rod 1011 and a second support rod 1012. The first support rod 1011 is rotatably connected to the second positioning rod 1022, and the first support rod 1011 is slidably sleeved on the outside of the second support rod 1012. The two adjacent sets of second support rods 1012 are horizontally rotatably connected to a rotating seat 1013 at their opposite ends, and a connecting rod 1014 is vertically rotatably connected between the two sets of rotating seats 1013.

[0073] like Figures 1 to 15 As shown, the design of the first support rod 1011 and the second support rod 1012 allows the length of the support plate 101 to be adjusted at will. Furthermore, the two sets of support plates 101 and the two sets of positioning plates 102 can be combined to form a horizontally placed tripod. The support plate 101 can stably support the photovoltaic panel, making the photovoltaic panel more stable.

[0074] It should be noted that, through the design of the rotating seat 1013 and the connecting rod 1014, the two adjacent sets of second bearing rods 1012 can not only rotate horizontally relative to each other, but also rotate vertically relative to each other. By rotating horizontally, the two sets of bearing plates 101 can be folded and retracted to the outside of the positioning plate 102 for easy carrying. By rotating vertically, the positioning plate 102 can be flipped open.

[0075] It is worth noting that the rotation angle center of the connecting rod 1014 and the rotating seat 1013 mentioned above is consistent with the flipping center of the positioning plate 102.

[0076] like Figure 15As shown, a stabilizing block 1015 is fixedly installed on the outer side of the second bearing rod 1012 mentioned above. When the bearing plate 101 is fully unfolded, the adjacent bearing plates 101 can be locked together by the stabilizing block 1015, so that the adjacent support mechanisms 1 can be fixed together, thereby further improving the stability of the photovoltaic support.

[0077] For example, such as Figure 1 As shown, Figure 1 In the folded state of one of the above-mentioned foldable photovoltaic mounting brackets, multiple bracket mechanisms 1 are folded at an angle, which can help the support column 3 contact the ground, so that the support column 3 is placed more stably on the ground. Therefore, the stability of the photovoltaic bracket when placed in the folded state can be further improved.

[0078] For example, the first synchronization mechanism 8, the second synchronization mechanism 1044, the third synchronization mechanism 4044 and the fourth synchronization mechanism 4045 mentioned above all use a structure of two sets of synchronization pulleys and synchronization belts for transmission. The use of synchronization pulleys and synchronization belts for transmission is a mature existing technology. Those skilled in the art should know how to install and use synchronization mechanisms. Therefore, the present invention will not elaborate on this.

[0079] For example, the first bevel gear transmission mechanism 1045, the second bevel gear transmission mechanism 2031, the third bevel gear transmission mechanism 2032, the fourth bevel gear transmission mechanism 2042, the fifth bevel gear transmission mechanism 401, the sixth bevel gear transmission mechanism 4047, and the seventh bevel gear transmission mechanism 406 mentioned above all use two sets of bevel gears meshing with each other to achieve reversing transmission. The method of using two sets of bevel gears for transmission has become a mature existing structural technology. Those skilled in the art should know how to install and use bevel gear transmission mechanisms. Therefore, this invention will not elaborate on it here.

[0080] The first bevel gear transmission mechanism 1045 mentioned above uses a large bevel gear to drive a small bevel gear, which can further increase the rotation speed of the telescopic screw 1047, allowing the second positioning rod 1022 to extend a longer distance.

[0081] Specifically, such as Figure 12 and Figure 16 As shown, the outer surface of the positioning shell 1041 is provided with a clearance hole. Its main function is to prevent the positioning shell 1041 from affecting the normal use of the second synchronization mechanism 1044 during rotation. A support rod 6 is fixedly installed on the upper surface of the fixed shell 1046, and the support rod 6 passes through the clearance hole and is rotatably connected to the first bevel gear transmission mechanism 1045.

[0082] The design of the support rod 6 can effectively improve the stability of the first bevel gear transmission mechanism 1045 during transmission.

[0083] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
