[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 16As shown in the figure, a foldable and deployable photovoltaic mounting bracket includes a support column 3 and a rotating base 5. The rotating base 5 is rotatably arranged at the upper end of the support column 3, and the rotating base 5 is detachably arranged at the upper end of the support column 3 by bolts. It further includes: A bracket mechanism 1, which is composed of four groups of support plates 103. Two groups of positioning plates 102 are symmetrically and rotatably connected to the ends of the four groups of support plates 103. A bearing plate 101 is arranged on the same side of the two groups of positioning plates 102. A driving mechanism 2, which is arranged on the rotating base 5. The support plate 103 is rotatably arranged with the rotating base 5 through the driving mechanism 2. As Figures 1 to 15 shown, due to the design that the support plate 103 is rotatably arranged with the rotating base 5 through the driving mechanism 2, multiple groups of support plates 103 can be flipped simultaneously, so that the bracket prototype can be quickly formed, further improving the installation efficiency of the photovoltaic bracket.

[0039] A folding and deploying mechanism 4, multiple groups of which are arranged, and the folding and deploying mechanism 4 is arranged on the support plate 103. The folding and deploying mechanism 4 is in transmission connection with the driving mechanism 2, and both groups of positioning plates 102 are rotatably arranged with the support plate 103 through the folding and deploying mechanism 4.

[0040] As Figures 1 to 15 shown, due to the design that the positioning plates 102 are rotatably arranged with the support plate 103 through the folding and deploying mechanism 4, when the support plate 103 is flipped to form the bracket prototype, the positioning plates 102 can be flipped relatively through the folding and deploying mechanism 4, so that the two groups of positioning plates 102 are deployed, and the positioning plates 102 and the support plate 103 are combined to form a rectangle, which is sufficient to carry the photovoltaic and perform the installation.

[0041] Furthermore, the driving 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. The first flipping component 203 and the second flipping component 204 are both arranged on the rotating base 5. The first flipping component 203 is used to drive the support plate 103 to be rotatably arranged, and the second flipping component 204 is in transmission connection with the folding and deploying mechanism 4. The first flip assembly 203 includes a first transmission gear 2033 and multiple groups of first driven gears 2034. Multiple groups of flip seats 402 are arranged around the upper surface of the rotating seat 5. The flip plate 403 is rotatably connected to the support plate 103, and the flip plate 403 is fixedly connected to the support plate 103. The first transmission gear 2033 is rotatably installed inside the rotating seat 5. The multiple groups of first driven gears 2034 are all meshed and connected with the outer side of the first transmission gear 2033. A fifth bevel gear transmission mechanism 401 that is transmission-connected to the first driven gear 2034 is arranged inside the flip seat 402. The flip plate 403 is rotatably arranged on the support plate 103 through the fifth bevel gear transmission mechanism 401, and the first transmission gear 2033 is rotatably installed inside the rotating seat 5 through the servo motor 202. 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 groups of first driven gears 2034 to rotate, so that the first driven gear 2034 controls the flip plate 403 through the fifth bevel gear transmission mechanism 401 to drive the support plate 103 to rotate, thereby realizing the simultaneous flipping and unfolding of multiple groups of support plates 103 to form a bracket prototype.

[0042] Furthermore, the second flip assembly 204 includes a second transmission gear 2044, which is rotatably mounted on the middle portion of the upper surface of the rotating seat 5 via the servo motor 202, and the folding and unfolding mechanism 4 is in transmission connection with the second transmission gear 2044; Specifically, Figures 1 to 5As shown in the figure, a deep groove is formed on the outer side of the rotating seat 5, and a damping groove is formed at one end inside the deep 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 deep groove, and one end of the damping push rod 201 is fixedly connected to the servo motor 202. The servo motor 202 is slidably installed inside the deep groove. One end of the output shaft of the servo motor 202 is fixedly installed with a linkage rod 205. A transmission groove is formed at the other end inside the deep groove. A second bevel gear transmission mechanism 2031 is arranged inside the transmission groove. The second bevel gear transmission mechanism 2031 is composed of two groups of meshing bevel gears. A plurality of convex points are arranged at one end of the outer circumference of the linkage rod 205. One group of bevel gears is slidably sleeved on the outer side of the linkage rod 205. The linkage rod 205 is engaged with one group of bevel gears through the convex points. A stabilizing rod 2041 is arranged inside the transmission groove. A fourth bevel gear transmission mechanism 2042 composed of two groups of meshing bevel teeth is arranged inside the transmission groove through the stabilizing rod 2041. A clamping groove is formed in the middle of one side of one group of bevel teeth. The linkage rod 205 is clamped inside the clamping groove through the convex points. The end of the second bevel gear transmission mechanism 2031 is drivingly connected with a sleeve housing 2035. The sleeve 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. The sleeve housing 2035 is rotatably sleeved on the outer side of the transmission rod 2043. The transmission rod 2043 is fixedly connected to the second transmission gear 2044.

[0043] 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, and further differentially control the rotating support plate 103 and the rotating positioning plate 102.

[0044] It should be noted that the servo motor 202 is slidably arranged inside the deep groove, so as to avoid the servo motor 202 rotating itself when driving the target structure to rotate; At the same time, by adopting the damping push rod 201, the position of the servo motor 202 can be quickly adjusted, and at the same time, the servo motor 202 can be prevented from automatically generating displacement, resulting in the inability to drive the target structure.

[0045] Further, the folding and unfolding mechanism 4 includes a linkage assembly 404 and a second driven gear 407, a stabilizing side plate 405 is fixedly mounted on one end of one side of the support plate 103, the linkage assembly 404 is arranged on one side of the stabilizing side plate 405, and a seventh bevel gear transmission mechanism 406 which is transmission-connected to the second driven gear 407 is arranged on the other side of the stabilizing side plate 405, and the two sets of positioning plates 102 are relatively rotatably arranged on the support plate 103 through the linkage assembly 404; 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 into the upper surface of the rotating seat 5 and enter a position meshing with the second transmission gear 2044. At this time, the second transmission gear 2044 can be controlled to rotate by the servo motor 202, so that the second driven gear 407 controls the driving of the linkage assembly 404 through the seventh bevel gear transmission mechanism 406, so that the linkage assembly 404 controls the positioning plate 102 to flip to a horizontal state, thereby completing the deployment and use of the bracket.

[0046] 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 electric drive of the servo motor 202. Therefore, this method not only does not require the staff to manually install the spliced ​​bracket, but also allows the entire bracket to be folded and retracted for carrying.

[0047] Further, the linkage assembly 404 includes a fixed seat 4048 and a fourth synchronization mechanism 4045, the fixed seat 4048 is fixedly installed on the other end of one side of the support plate 103, and the two ends of the upper surface of the fixed seat 4048 are fixedly installed with a bearing shell 4041, and the ends of the two groups of positioning plates 102 close to each other are fixedly installed with a rotating gear 105, and the two groups of rotating gears 105 are meshed with each other. The positioning plates 102 are rotatably installed on one side of the bearing shell 4041, and the other side of one group of the bearing shells 4041 is provided with a third synchronization mechanism 4044, and one end of the third synchronization mechanism 4044 is transmission-connected with one of the groups of rotating gears 105, and the other end of the third synchronization mechanism 4044 is transmission-connected with a sixth bevel gear transmission mechanism 4047, and the fourth synchronization mechanism 4045 is transmission-installed between the sixth bevel gear transmission mechanism 4047 and the seventh bevel gear transmission mechanism 406; Specifically, Figures 1 to 15 As shown, connecting seats 4042 are fixedly installed at both ends of the bottom of the fixed seat 4048, and the connecting seats 4042 are fixedly connected to the support plate 103, one group of connecting seats 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, and the end of the fourth synchronization mechanism 4045 is arranged inside the connection between the protective shell 4043 and the connecting seat 4042.

[0048] Specifically, a driving rod 4046 is fixedly installed at the end of the third synchronization mechanism 4044 described above, and the driving rod 4046 penetrates through the bearing housing 4041 and is fixedly connected to one set of rotating gears 105.

[0049] Through the design of the connecting seat 4042 and the protective housing 4043, the symmetrically designed connecting seat 4042 can make the fixed seat 4048 more stably connected to the support plate 103. Secondly, the protective housing 4043 can protect the sixth bevel gear transmission mechanism 4047 and the third synchronization mechanism 4044, preventing their structures from being exposed and affecting normal use.

[0050] As Figures 1 to 15 shown, through the design of the 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 rotation of the driving rod 4046 through the sixth bevel gear transmission mechanism 4047 and the third synchronization mechanism 4044, causing the two sets of rotating gears 105 to rotate relative to each other, thereby realizing the relative flipping and unfolding of the two combined positioning plates 102, making the bracket fully unfolded and facilitating the installation and use of the photovoltaic panel.

[0051] Specifically, the support plate 103 described above is composed of an arc-shaped plate 1031, a deformation plate 1032, and a deformation spring 1033. The arc-shaped plate 1031 is fixedly connected to the flipping plate 403 and the connecting seat 4042. A deformation groove is provided inside the arc-shaped plate 1031. The deformation spring 1033 is arranged inside the deformation groove, and the deformation plate 1032 is fixedly installed around the inner circumference of the arc-shaped plate 1031 for one week. The deformation spring 1033 is fixedly connected to the deformation plate 1032.

[0052] Exemplarily, the deformation plate 1032 described above can be made of flexible steel plate material. Thus, when the arc-shaped plate 1031 flips and unfolds, the deformation plate 1032 changes its arc angle to the opposite through the elastic extrusion of the deformation spring 1033, making the overall shape of the support plate 103 transform into a flat arc shape. This state can better reduce wind resistance and make the photovoltaic use more stable.

[0053] Furthermore, the bracket mechanism 1 further includes two sets of extension components 104. 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 outside the second positioning rod 1022. The rotating gear 105 is fixedly installed at one end of the first positioning rod 1021, and the first positioning rod 1021 is rotatably connected to the bearing housing 4041. The extension component 104 is arranged on one side of the first positioning rod 1021; As Figures 1 to 15As shown, through the design that the positioning plate 102 is composed 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 scene and usage conditions, so as to further improve the practicality of the photovoltaic mounting bracket.

[0054] Furthermore, the extension assembly 104 includes a positioning shell 1041, a driving gear 1042 and a fixed shell 1046. The positioning shell 1041 is fixedly installed on one side of the first positioning rod 1021, the driving gear 1042 is fixedly installed on one side of the positioning shell 1041, 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 outer side of the positioning shell 1041, and a linkage gear 1043 meshing with the driving gear 1042 is rotatably installed on one side of the fixed shell 1046. The fixed shell 1046 and the positioning shell 10 A second synchronization mechanism 1044 is arranged between the positioning housing 1041, the linkage gear 1043 is transmission-connected with the second synchronization mechanism 1044, and a stabilizing plate 1048 is rotationally connected between the linkage gear 1043 and the same side of the driving gear 1042; a gear speed change mechanism 9 is arranged inside the positioning housing 1041, and the gear speed change mechanism 9 is transmission-connected with the second synchronization mechanism 1044, and a telescopic screw rod 1047 is rotationally connected to the outer side of the positioning housing 1041 through the gear speed change mechanism 9, and one end of the second positioning rod 1022 is threadedly sleeved on the outer side of the telescopic screw rod 1047; like Figures 1 to 15 As shown, through the design of the driving gear 1042 and the linkage gear 1043, when the rotating gear 105 drives the positioning plate 102 to flip as a whole, the positioning plate 102 drives the driving gear 1042 to rotate, and the linkage gear 1043 in the fixed position will rotate through the rotating driving gear 1042. The linkage gear 1043 passes through the second synchronization mechanism 1044, so that the first bevel gear transmission mechanism 1045 controls the telescopic screw 1047 to rotate through the gear change mechanism 9, so that the telescopic screw 1047 drives the second positioning rod 1022 to extend, so that it can automatically extend when it reaches the length of the positioning plate 102.

[0055] Specifically, Figure 13As shown, the gear shifting mechanism 9 described above is composed of multiple sets of driving variable-speed gears 901 and multiple sets of driven variable-speed gears 902, and the driving variable-speed gears 901 and the driven variable-speed gears 902 are arranged in a staggered manner. A square pull rod 7 is commonly installed in the middle of multiple sets of driven variable-speed gears 902. One end inside the positioning shell 1041 is provided with a shifting slot, and a first synchronization mechanism 8 is arranged at one end inside the shifting slot. The end of the first synchronization mechanism 8 is slidably sleeved outside the square pull rod 7. The telescopic lead screw 1047 is in transmission connection with the first synchronization mechanism 8. Multiple sets of driving variable-speed gears 901 are fixedly arranged with each other, and one set of driving variable-speed gears 901 is in transmission connection with the first bevel gear transmission mechanism 1045.

[0056] Through the design of the gear shifting mechanism 9, during the rotation of the positioning plate 102, the first bevel gear transmission mechanism 1045 can drive the pre-adjusted gear shifting mechanism 9 to rotate, so that the rotation speeds of the telescopic lead screw 1047 are different, and thus the extended lengths of the second positioning rods 1022 can be different. Therefore, the photovoltaic installation bracket can adjust the optimal photovoltaic support area according to different usage scenarios, further improving the practicality of the photovoltaic installation bracket.

[0057] Furthermore, the bearing plate 101 is composed of a first bearing rod 1011 and a second bearing rod 1012. The first bearing rod 1011 is rotatably connected to the second positioning rod 1022, and the first bearing rod 1011 is slidably sleeved outside the second bearing rod 1012. The opposite ends of adjacent two groups of second bearing rods 1012 are horizontally rotatably connected with a rotating seat 1013, and a connecting rod 1014 is vertically rotatably connected between the two rotating seats 1013; As Figures 1 to 15 shown, due to the design of the first bearing rod 1011 and the second bearing rod 1012, the length of the bearing plate 101 can be adjusted arbitrarily, and the two bearing plates 101 and the two positioning plates 102 can be combined to form a horizontally placed tripod. The bearing plate 101 can stably support the photovoltaic panel, making the photovoltaic panel more stable.

[0058] It should be noted that through the design of the rotating seat 1013 and the connecting rod 1014, adjacent two groups of second bearing rods 1012 can not only rotate horizontally with each other, but also rotate vertically with each other. By rotating horizontally, the two bearing plates 101 can be folded and contracted to the outside of the positioning plate 102, which is convenient for carrying. By rotating at a vertical angle, it can cooperate with the positioning plate 102 to flip and open.

[0059] It is worth noting that the rotation angle center of the connecting rod 1014 and the rotating seat 1013 described above is the same as the flipping center of the positioning plate 102.

[0060] As Figure 15As shown, a stabilizing block 1015 is fixedly installed on the outer side of the second bearing rod 1012 in the above. When the bearing plate 101 is fully unfolded, adjacent bearing plates 101 can be clamped to each other through the stabilizing block 1015, so that adjacent bracket mechanisms 1 can be fixed to each other, thereby further improving the stability of the photovoltaic bracket.

[0061] Exemplarily, as Figure 1 shown, Figure 1 For a folded state of the folding and unfolding type photovoltaic mounting bracket in the above, multiple bracket mechanisms 1 are folded at an angle, which can assist the support column 3 to contact the ground, so that the support column 3 is placed on the ground more stably. Therefore, the stability of the photovoltaic bracket after being folded can be further improved.

[0062] Exemplarily, the first synchronization mechanism 8, the second synchronization mechanism 1044, the third synchronization mechanism 4044, and the fourth synchronization mechanism 4045 in the above all adopt a structure of two synchronous wheels and a synchronous belt for transmission. Using synchronous wheels and a synchronous belt for transmission has already become an existing mature technology, and those skilled in the art should know how to install and use the synchronization mechanism. Therefore, the present invention will not elaborate here.

[0063] Exemplarily, 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 in the above all adopt a method of two bevel gears meshing with each other to achieve reverse transmission. The method of using two bevel gears for transmission has already become an existing mature structural technology, and those skilled in the art should know how to install and use the bevel gear transmission mechanism. Therefore, the present invention will not elaborate here.

[0064] Among them, the first bevel gear transmission mechanism 1045 in the above adopts a method of a large bevel gear driving a small bevel gear for transmission, so as to further increase the rotation speed of the telescopic lead screw 1047, so that the second positioning rod 1022 can extend a longer distance.

[0065] Specifically, as Figure 12 and Figure 16 shown, an avoidance hole is provided on the outer surface of the positioning shell 1041 in the above. Its main function is to avoid affecting the normal use of the second synchronization mechanism 1044 during the rotation of the positioning shell 1041. A support rod 6 is fixedly installed on the upper surface of the fixed shell 1046, and the support rod 6 passes through the inside of the avoidance hole and is rotationally connected to the first bevel gear transmission mechanism 1045.

[0066] Through the design of the support rod 6, the stability of the first bevel gear transmission mechanism 1045 during transmission can be effectively improved.

[0067] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
