If "several" appears in the present invention, it means two or more.

[0030] First, the overall technical solution of the present invention is introduced.

[0031] The present invention discloses a photovoltaic support 100, including a column 4, an inclined beam 5 and a transmission assembly. The inclined beam 5 can be rotatably mounted on the column 4. The transmission assembly includes a transmission rod 6, a transmission member 3 and a rotating member 2. One end of the transmission rod 6 is rotatably connected to the inclined beam 5 and the other end is movably connected to the column 4, and the transmission assembly can drive the inclined beam 5 to rotate under the drive of a driving member (not shown). The transmission member 3 includes a first transmission member (for example, the second rack 32 in the specific embodiment) and a second transmission member (for example, the first rack 31 in the specific embodiment) arranged relatively spaced apart, the first transmission member is fixedly mounted on the transmission rod 6, and the rotating member 2 is movably mounted on the transmission rod 6 and is located between the first transmission member and the second transmission member, so that the rotating member 2 can engage with the first transmission member and separate from the second transmission member, or the rotating member 2 can engage with the first transmission member and the second transmission member at the same time. When the rotating member 2 is engaged with the first transmission member and the second transmission member at the same time, the transmission assembly is in a locked state; when the rotating member 2 is engaged with the first transmission member and separated from the second transmission member, the transmission assembly is in an unlocked state. The present invention switches the state by moving the rotating member 2, and can achieve the technical effect of unlocking and locking the transmission assembly, with a simple structure and easy operation.

[0032] Furthermore, a plurality of the columns 4 are arranged at intervals, and each of the columns 4 is equipped with the diagonal beam 5 and the transmission assembly. The photovoltaic support further comprises a coupling 1, and the coupling 1 is used to connect with the driving member, and can transmit the power of the driving member to each of the diagonal beams 5. The function of the coupling 1 is to connect the transmission assemblies on the plurality of the columns 4 as a whole, so as to synchronously drive the plurality of diagonal beams 5 on the plurality of the columns 4. The present invention achieves the technical effect of synchronous unlocking and synchronous locking of the transmission assembly by driving the synchronous movement of the plurality of rotating members 2 through the coupling 1 to switch the synchronous state.

[0033] Furthermore, the present invention further comprises an elastic reset component 7. The elastic reset component 7 cooperates with the coupling 1 to automatically reset the unlocked state to the locked state.

[0034] Furthermore, the elastic reset assembly 7 includes a coil spring 71 and a spring pressure plate 72 sleeved on the coupling 1. One end of the coil spring 71 can abut against the column 4 and the other end can abut against the spring pressure plate 72. The coupling 1 has an annular protrusion 102, and the annular protrusion 102 abuts against the side of the spring pressure plate 72 away from the coil spring 71. When an external force acts on the coupling 1 to move the coupling 1 axially toward the column 4, the coil spring 71 can be compressed by the coupling 1. The compressed coil spring 71 can release its elastic force and reset after the external force disappears, thereby driving the coupling 1 to move axially away from the column 4, thereby realizing the reset of the rotating member 2 from the unlocked state to the locked state. In short, the function of the elastic reset assembly 7 is to provide an elastic restoring force for converting the transmission assembly from the unlocked state to the locked state; the function of the spring pressure plate 72 is to facilitate the abutment between the coupling 1 and the coil spring 71.

[0035] Further, the elastic reset assembly 7 includes a spring guide cylinder 70 sleeved on the coupling 1 and fixed to the column 4, and the coil spring 71 and the spring pressure plate 72 are accommodated in the spring guide cylinder 70. The spring guide cylinder 70 includes a cylindrical side wall 701 and a baffle 702, and the baffle 702 is fixed to an end of the cylindrical side wall 701 away from the column 4. In the elastic release state of the coil spring 71, the spring pressure plate 72 can abut against the baffle 702. The function of the spring guide cylinder 70 is to provide the coil spring 71 and the spring pressure plate 72 with the function of limiting and guiding.

[0036] Furthermore, the elastic reset assembly 7 includes a thrust roller bearing 73 sleeved on the coupling 1, and in the radial direction of the coupling 1, the thrust roller bearing 73 is located between the spring pressure plate 72 and the annular protrusion 102. The thrust roller bearing 73 is used to provide a rotational friction force between the spring pressure plate 72 and the coupling 1.

[0037] Furthermore, the second transmission member is fixedly mounted on the transmission rod 6. In a specific embodiment, the rotating member 2 is a gear, and the first transmission member and the second transmission member are both racks that have a self-locking effect on the gear. The gear can move in the width direction of the rack so that the gear can only mesh with one of the racks, or the gear can mesh with two racks at the same time. The way in which one gear corresponds to the upper and lower racks makes the transmission assembly in the present invention simple in structure and easy to operate. In other embodiments of the present invention, the matching method of the gear rack can also be replaced by a worm gear, which will not be repeated in the present invention.

[0038] Further, the transmission rod 6 includes an upper wing plate 61 and a lower wing plate 62 which are arranged opposite to each other. The rack includes a first rack fixedly arranged on the upper wing plate 61 and a second rack fixedly arranged on the lower wing plate 62, and the width of the first rack is smaller than the width of the second rack. In this way, the widths of the first rack and the second rack are different, which determines that the rotating member 2 (gear) has two different matching states between the gear and the rack before and after the movement, that is, the rotating member 2 (gear) not only has an unlocking state in which it can only mesh with the second rack, but also has a locking state in which it can mesh with the first rack and the second rack at the same time. Further, the transmission rod 6 includes a base plate 60, the upper wing plate 61 and the lower wing plate 62 are formed by bending in the same direction from the upper and lower edges of the base plate 60 respectively, and the base plate 60 is provided with a long waist hole 601 for the coupling 1 to pass through, and the longitudinal extension direction of the long waist hole 601 is consistent with the length direction of the rack. The specific shape of the transmission rod 6 facilitates the fixed installation of the first rack and the second rack and the installation and positioning between the first rack, the second rack and the gear. The purpose of setting the long waist hole 601 is to enable the transmission rod 6 to move obliquely during the rotation of the rotating part 2.

[0039] Furthermore, the coupling 1 further comprises a pile inner shaft 11 and an inter-pile connecting shaft 12. The pile inner shaft 11 is correspondingly passed through each of the upright columns 4, and the inter-pile connecting shaft 12 is fixedly connected between two adjacent pile inner shafts 11. The coupling 1 is composed of the pile inner shaft 11 and the inter-pile connecting shaft 12 connected to each other as a whole. Before connection, the coupling 1 is a separate piece, which is convenient for transportation and assembly; after connection, it is a whole piece that can be transmitted, meeting the needs of linkage.

[0040] Hereinafter, a specific embodiment of the present invention in which the transmission assembly is engaged and separated by a gear rack (the rotating member 2 is a gear, and the first transmission member and the second transmission member are both racks that have a self-locking effect on the gear) will be introduced in conjunction with the drawings of the specification.

[0041] Please refer to Figures 1 to 11 As shown, the present invention discloses a photovoltaic bracket 100 for adjusting the angle of a photovoltaic module (not shown), which includes a coupling 1, a gear 2, a rack 3, a column 4, a diagonal beam 5, a transmission rod 6 and an elastic reset component 7. Please refer to Figure 1 , Figure 2 and Figure 8For the convenience of description, the photovoltaic bracket 100 of the present invention has an up-down direction, a left-right direction and a front-back direction. Among them, the column 4 extends in the up-down direction and the coupling 1 extends in the left-right direction, and the front-back direction, the up-down direction, and the left-right direction are perpendicular to each other. The photovoltaic bracket 100 of the present invention can adjust the angle of the photovoltaic component by pushing it first and then rotating it. It has a simple structure and is easy to operate. The present invention also provides an elastic reset component 7, and the elastic reset component 7 converts the gear 2 from an unlocked state to a locked state. The photovoltaic bracket 100 of the present invention is efficient and reliable in adjusting the angle of the photovoltaic component.

[0042] Please continue to refer to Figures 1 to 11 As shown, the coupling 1 is passed through the column 4 and fixed with the gear 2, the inclined beam 5 is rotatably connected to the top of the column 4 for fixing and installing the photovoltaic component, the transmission rod 6 is rotatably connected with the inclined beam 5 and movably connected with the column 4, the rack 3 is two upper and lower ones and is respectively fixed as a whole with the transmission rod 6, the gear 2 can move in the width direction of the rack 3 under the axial pushing action of the coupling 1, the gear 2 is meshed with the two racks 3 at the same time so that the gear 2 has a locked state that cannot rotate, the gear 2 is meshed with one of the two racks 3 and separated from the other so that the gear 2 has an unlocked state that can rotate; the coupling 1 can drive the gear 2 to rotate relative to the rack 3 when it is in the unlocked state, and then can drive the inclined beam 5 to rotate through the transmission rod 6 to adjust the angle of the photovoltaic component; the elastic reset component 7 cooperates with the coupling 1, and is used to reset the unlocked state to the locked state, and then lock the photovoltaic component at the adjusted angle.

[0043] Please refer to Figure 3 , Figure 4 and Figure 8 As shown, the transmission rod 6 includes an upper wing plate 61 and a lower wing plate 62 arranged opposite to each other. The rack 3 includes a first rack 31 fixedly arranged on the upper wing plate 61 and a second rack 32 fixedly arranged on the lower wing plate 62. Therefore, there is no relative position change between the first rack 31 and the second rack 32 at any time. Please refer to Figure 8It can be understood that the first rack 31 and the second rack 32 are both arranged on the right side of the transmission rod 6 and the first rack 31 and the second rack 32 are aligned near the right side end of the column 1. Since the width of the first rack 31 is smaller than the width of the second rack 32, the first rack 31 is a narrow rack and the second rack 32 is a wide rack. In a specific embodiment, it can be said that the first rack 31 forms a missing distribution above the second rack 32: the first rack 31 and the second rack 32 are synchronously meshed with the upper and lower parts of the gear 2 in the width direction of the rack 3, so that the gear 2 cannot rotate to put the gear 2 in the locked state; the second rack 32 is meshed with the gear 2 and the first rack 31 is separated from the gear 2, so that the gear 2 can rotate to put the gear 2 in the unlocked state.

[0044] In other embodiments not shown in the figure, the first rack 31 and the second rack 32 have equal widths and are staggered, and the two different states of the gear 2, namely, the "locked state" and the "unlocked state", can also be achieved. It is only necessary that the right ends of the first rack 31 and the second rack 32 are not aligned. In other words, the present invention does not emphasize or limit whether the widths of the two racks 3 are equal; in addition, because the gear 2 is fixed to the coupling 1 and does not float up and down, in other embodiments, the gear 2 can be rotated to put the gear 2 in the unlocked state by swapping the positions of the narrow rack and the wide rack up and down, so that the narrower first rack 31 is located at the bottom and the wider second rack 32 is located at the top, so that the upper and wider second rack 32 is meshed with the gear 2 and the lower and narrower first rack 31 is separated from the gear 2, and the meshing and separation of the second rack 32 and the gear 2 in the unlocked state will not be caused. It can be understood here that the present invention does not need to rely on the wider rack 3 (the second rack 32) to support the gear 2, and does not need to use this to maintain the engagement of the single rack 3 with the gear 2 in the unlocked state. In other words, the present invention does not emphasize whether the gear 2 is engaged with the upper or lower rack 3 in the unlocked state.

[0045] Please refer to Figures 2 to 4As shown, the transmission rod 6 includes a base plate 60 located on the right side, and the upper wing plate 61 and the lower wing plate 62 are formed by bending in the same direction from the upper and lower edges of the base plate 60 on the right side, respectively. The upper end of the base plate 60 on the right side is rotatably connected to one end of the inclined beam 5, and the longer part of the base plate 60 on the right side away from the upper end is provided with a long waist hole 601 for the coupling 1 to pass through, and the longitudinal extension direction of the long waist hole 601 is consistent with the length direction of the rack 3. The function of the long waist hole 601 is that the coupling 1 passes through the long waist hole 601, so that the movement of the transmission rod 6 on the column 4 can be limited within a certain range through the long waist hole 601.

[0046] In other embodiments, the transmission rod 6 may not include the base plate 60 disposed on the right side, and the base plate 60 on the right side only serves to connect and fix the upper wing plate 61 and the lower wing plate 62. For example, after the base plate 60 on the right side is removed, the upper wing plate 61 and the lower wing plate 62 may be connected and fixed respectively by a front plate (not shown) and a rear plate (not shown) disposed opposite to each other. In this case, the right side where the entire base plate 60 is located is equivalent to a large long strip space, and the coupling 1 passes through the long strip space. The front plate can limit the forward movement of the transmission rod 6, and the rear plate can limit the backward movement of the transmission rod 6.

[0047] Please refer to Figures 3 to 10 As shown, the coupling 1 first includes a drive shaft 111 located on the far right. One end of the drive shaft 111 is provided with a pin hole 90 for the pin 9 to pass through, and the other end includes a hexagonal end 101. The hexagonal end 101 is conveniently connected to an external motor (not shown, such as a handheld drive motor or a handheld rocker). When the gear 2 is in the unlocked state, the external motor drives the coupling 1 to rotate and drives the gear 2 to rotate in situ in the unlocked state; during the in-situ rotation of the gear 2, the meshing between the second rack 32 and the gear 2 causes the rack 3 on the transmission rod 6 to move relative to the gear 2, so as to drive the movement of the transmission rod 6 on the column 4, thereby driving the rotation of the inclined beam 5 relative to the column 4.

[0048] Please refer to Figures 1 to 10 As shown, the columns 4 are arranged in a row of at least two. In addition to the coupling 1 being one and the racks 3 being arranged two to one on each column 4, the gears 2, the inclined beams 5 and the transmission rods 6 are all arranged one to one on each column 4. Each column 4 is provided with a through hole 40 for the coupling 1 to pass through. Figures 9 to 11As shown, the coupling 1 further comprises a pile inner shaft 11 and an inter-pile connecting shaft 12, wherein the pile inner shaft 11 is passed through each of the upright columns 4, and each of the inter-pile connecting shaft 12 is provided with a pin hole 90 at opposite ends thereof, which is the same as the rightmost driving shaft 111. The inter-pile connecting shaft 12 is fixedly connected between two adjacent pile inner shafts 11 by passing the pin 9 through the pin hole 90. Except for the rightmost pile inner shaft 11 used as a driving shaft 111 directly connected to an external motor, the remaining pile inner shafts 11 and the inter-pile connecting shafts 12 are all used as transmission shafts. For example, when there are three columns 4 arranged in a row, the inner shaft member 11 of the rightmost column 4 is the driving shaft 111, and the inner shaft member 11 of the leftmost column 4 is the tail shaft 113. Accordingly, the inner shaft member 11 between the driving shaft 111 and the tail shaft 113 can be called the intermediate shaft 112; one of the inter-pile connecting shaft members 12 is connected between the driving shaft 111 and the intermediate shaft 112, and the other inter-pile connecting shaft member 12 is connected between the intermediate shaft 112 and the tail shaft 113. Therefore, the external motor can drive the rotation of the inclined beams 5 on the plurality of columns 4 arranged in a row relative to the columns 4 at one time.

[0049] The above introduces how the photovoltaic bracket 100 of the present invention is driven to achieve the conversion from the "locked state" to the "unlocked state" and how to rotate in the unlocked state to achieve adjustment; the following will focus on how the photovoltaic bracket 100 of the present invention is reset from the unlocked state to the locked state.

[0050] Please refer to Figures 3 to 8 As shown, the elastic reset assembly 7 includes a coil spring 71 sleeved on the coupling 1, and one end of the coil spring 71 facing the column 4 can abut against the column 4. When an external force acts on the coupling 1 to move the coupling 1 axially toward the column 4, the coil spring 71 can be compressed by the coupling 1 toward the column 4; the compressed coil spring 71 can release elastic force and reset after the external force disappears.

[0051] Please refer to Figures 3 to 8As shown, the elastic reset assembly 7 includes a spring guide cylinder 70 sleeved on the coupling 1 and fixed to the column 4, and the coil spring 71 is accommodated in the spring guide cylinder 70. The spring guide cylinder 70 includes a cylindrical side wall 701, a baffle 702 and a flange plate 703. The baffle 702 and the flange plate 703 are fixed to the opposite ends of the cylindrical side wall 701 and are both annular in shape so that the coupling 1 can pass through. The spring guide cylinder 70 is fixed to the column 4 by bolts 8 passing through the flange plate 703 and fixed to the column 4. The baffle 702 and the flange plate 703 are separately formed from the cylindrical side wall 701 and then welded and fixed, which facilitates the assembly of the coil spring 71 and other components.

[0052] Please continue to refer to Figures 3 to 8 As shown, the elastic reset assembly 7 includes a spring pressure plate 72, which is also sleeved on the coupling 1 and accommodated in the spring guide cylinder 70. The side of the spring pressure plate 72 facing the column 4 can abut against the other end of the coil spring 71 away from the column 4. The annular radius of the spring pressure plate 72 is greater than the annular radius of the baffle 702. When the coil spring 71 is in the elastic release state, the other side of the spring pressure plate 72 away from the column 4 can abut against the baffle 702. The function of the spring pressure plate 72 is to prevent the coupling 1 from directly abutting against the coil spring 71, so that the driving force of the coupling 1 acts on the right end of the coil spring 71 in a more balanced manner. The material of the spring pressure plate 72 is a rigid material; in order to avoid sharp friction between the right end of the coil spring 71 and the spring pressure plate 72, more preferably, a spring gasket 74 of a flexible material is also provided between the right end of the coil spring 71 and the spring pressure plate 72.

[0053] It is particularly important to point out that, because the spring pressure plate 72 is only sleeved on the coupling 1 and is not fixed to the cylindrical side wall 701 of the spring guide cylinder 70, the spring pressure plate 72 cannot rotate with the coupling 1, and the coupling 1 is the mechanical rotating body in the present invention. Figure 2 , Figure 4 and Figure 8As shown, the elastic reset assembly 7 also includes a thrust roller bearing 73 sleeved on the coupling 1. In the radial direction of the coupling 1, the thrust roller bearing 73 is located between the spring pressure plate 72 and the coupling 1. The coupling 1 has an annular protrusion 102, and in the axial direction of the coupling 1, the annular protrusion 102 abuts against the other side of the thrust roller bearing 73 away from the column 4. An annular cavity 7020 is formed between the baffle 702 and the coupling 1, allowing the thrust roller bearing 73 and the annular protrusion 102 to be exposed outside the spring guide cylinder 70. The function of the thrust roller bearing 73 is to provide a rotational friction force between the spring pressure plate 72 and the coupling 1, support the mechanical rotating body, i.e., the coupling 1, reduce the friction coefficient (friction coefficient) during the movement of the coupling 1, and ensure its rotation accuracy (accuracy).
