Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] The core of this utility model is to provide a photovoltaic support bracket, which adjusts the inclination of the crossbeam relative to the installation area through a first adjusting component and a second adjusting component, thereby adjusting the inclination of the photovoltaic modules on the crossbeam relative to the installation area. This allows the photovoltaic support bracket to be adaptively adjusted according to the solar altitude angle, ensuring that the photovoltaic modules on the crossbeam are always perpendicular to the sun and guaranteeing power generation efficiency.

[0044] The photovoltaic bracket provided by this utility model is used to support the photovoltaic module 1. Specifically, it is used to support and connect the photovoltaic module 1 to its installation area 5. The installation area 5 can be a roof or an open-air experimental area or other areas that need to utilize the power of the photovoltaic module 1, and is not limited thereto.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 The photovoltaic support specifically includes a crossbeam 2, a first adjusting component 3, a second adjusting component 4, and a locking component.

[0046] The crossbeam 2 is used to connect the photovoltaic module 1. By changing the inclination of the crossbeam 2 relative to the installation area 5, the inclination of the photovoltaic module 1 on the crossbeam 2 is changed.

[0047] The first end of the first adjusting member 3 is rotatably connected to the first end of the crossbeam 2, and the second end of the first adjusting member 3 is rotatably connected to the installation area 5 of the photovoltaic module 1. When tilt adjustment is required, the first adjusting member 3 can extend and retract to change the height of the crossbeam 2. The two ends of the first adjusting member 3 can also rotate according to the adjustment situation to change the tilt of the crossbeam 2.

[0048] In one embodiment, the first adjusting member 3 can be telescopically connected by a sleeve structure, with two or more sleeves connected to form a telescopic structure.

[0049] In another embodiment, the first adjusting member 3 can be extended and retracted by means of a lifting member, which is connected to the first adjusting member 3 to adjust the height of the first adjusting member 3. The lifting member is specifically such as a cylinder.

[0050] In another embodiment, the first adjusting member is telescopic and can be adjusted by means of a gear and rack structure, which connects the first adjusting member 3 through gears, thereby achieving the height adjustment of the first adjusting member 3.

[0051] The first end of the second adjusting member 4 is rotatably connected to the second end of the crossbeam 2. The second end of the second adjusting member 4 is fixed to the mounting area 5. When tilt adjustment is required, the second adjusting member 4 can contract or expand to change the height of the crossbeam 2. The second adjusting member 4 can also rotate relative to the second end of the crossbeam 2 to change the tilt of the crossbeam 2.

[0052] In one embodiment, the second adjusting member 4 can specifically achieve contraction or expansion by adopting a cross lifting structure, where the lifting of the cross lifting structure corresponds to the relative contraction or relative expansion between the cross components.

[0053] In another embodiment, the second adjusting member 4 specifically achieves contraction or expansion by adopting a frame structure formed by two or more hinged links, and the overall contraction or expansion of the second adjusting member 4 is achieved by the rotation of the links relative to the hinge points.

[0054] When adjusting the inclination of the crossbeam 2, this is achieved through the joint operation of the first adjusting member 3 (which can extend and / or rotate) and the second adjusting member 4 (which can rotate and / or contract and expand). This joint operation can specifically refer to, for example, the first adjusting member 3 extending and rotating, and the second adjusting member 4 rotating and contracting / expanding; or the first adjusting member 3 extending and the second adjusting member 4 rotating and contracting / expanding. There are no restrictions on how this joint operation is coordinated, whether it involves extension or shortening, expansion or contraction, or forward or reverse rotation; the specific operation should be adapted to the actual adjustment situation. Figures 1 to 3 As shown in the figure, α represents the tilt angle of the beam 2, which is also the tilt angle of the photovoltaic module 1. The tilt angle of the photovoltaic module 1 can be infinitely adjusted via the first adjusting member 3 and the second adjusting member 4, ensuring that the photovoltaic module 1 is perpendicular to the direction of solar incidence and guaranteeing power generation efficiency.

[0055] Furthermore, since both the first adjusting member 3 and the second adjusting member 4 have active and locked states, when adjustment is needed, the first adjusting member 3 and the second adjusting member 4 must be adjusted to the active state, allowing the first adjusting member 3 to extend and rotate, and the second adjusting member 4 to rotate and contract. After adjustment is completed, specifically after adjusting the inclination of the crossbeam 2, the first adjusting member 3 and the second adjusting member 4 must be adjusted to the locked state to ensure reliable support for the photovoltaic module 1. Locking the first adjusting member 3 and the second adjusting member 4 is achieved by using the locking components, thus switching between the active and locked states of the first adjusting member 3 and the second adjusting member 4.

[0056] For example, locking components may include blocking blocks that restrict rotation, stop members that restrict extension and retraction, bolt and nut assemblies that restrict extension and retraction, etc., which can achieve the effect of locking and unlocking components in specific applications.

[0057] For example, when the rotation-restricting blocking block is applied to the first adjusting member 3, the blocking block can extend into the first adjusting member 3 to restrict its movement or block the side of the first adjusting member 3 to restrict its movement when the adjustment is completed, and the blocking block retracts when the adjustment is performed.

[0058] In this embodiment, it should be noted that the first adjusting member 3 and the second adjusting member 4 can be arranged in two or more sets. Specifically, this is to facilitate reliable and effective support for the photovoltaic module 1, and to allow for different or the same degree of adjustment to each first adjusting member 3 and each second adjusting member 4 according to the slope of the installation area 5, so as to ensure that the lower end of the photovoltaic module 1 is always on the same horizontal line in the same direction, thereby improving the power generation efficiency of the photovoltaic system and ensuring the stability and overall aesthetics of the photovoltaic bracket.

[0059] Based on the above embodiments, please refer to Figure 1 , Figure 6The second adjusting member 4 includes a first fixing member 41, a second fixing member 42, and a crossbar 45.

[0060] The first fixing member 41 is rotatably connected to the second end of the crossbeam 2. When the tilt of the crossbeam 2 needs to be adjusted, the second end of the crossbeam 2 can rotate relative to the first fixing member 41. After adjustment, the second end of the crossbeam 2 is locked to the first fixing member 41 by a locking assembly to complete the locking. The second fixing member 42 is provided with mounting holes for fixing to the mounting area 5 to form a support. At least two crossbars 45 are provided between the first fixing member 41 and the second fixing member 42 to form a retractable and expandable structure. One end of the crossbar 45 is hinged to the first fixing member 41, and the other end of the crossbar 45 is hinged to the second fixing member 42. The structure formed by the at least two crossbars 45 here is a symmetrical structure. The crossbars 45 located on both sides of the first fixing member 41 and the second fixing member 42 are relatively close to each other to form a retracted state, and relatively far apart to form an expanded state.

[0061] Both the first fixing member 41 and the second fixing member 42 can be provided with holes for easy hinge connection. The specific number of holes can be set according to the number of matching crossbars 45.

[0062] In this embodiment, the number of crossbars 45 can be 2, 4, 6, 8, etc., without limitation, as long as a telescopic expansion structure can be formed.

[0063] The locking assembly is used to lock or unlock the crossbar 45 to correspondingly restrict or unlock the movement of the retractable and expandable structure, or to lock or unlock the first fixing member 41 to correspondingly restrict or unlock the rotation of the second end of the crossbeam 2. When the second adjusting member 4 is required for adjustment, the locking assembly unlocks the crossbar 45 and the first fixing member 41; after adjustment is completed, the locking assembly locks the crossbar 45 and the first fixing member 41.

[0064] Based on any of the above embodiments, please refer to Figure 1 , Figure 6 There are four crossbars 45. The four crossbars 45, the first fixing member 41, and the second fixing member 42 together form a frame structure. The four crossbars 45 in this frame structure can be made movable through a hinged relationship to achieve the effect of contraction and expansion of the second adjusting member 4, thereby indirectly realizing the adjustment of the height of the second end of the crossbeam 2.

[0065] Four crossbars 45 are symmetrically arranged along the centerline of the first fixing member 41 and the second fixing member 42, with two crossbars 45 on the same side of the centerline hinged together. That is, two crossbars 45 are provided on both the left and right sides of the centerline. Besides the hinged ends, the other end of each crossbar 45 is hinged to either the first fixing member 41 or the second fixing member 42. When adjustment is required, the crossbars 45 and the first fixing member 41 are unlocked using the locking assembly. Specifically, unlocking allows the crossbars 45 to rotate around the hinge point and around the first and second fixing members 41 and 42, enabling the second adjusting member 4 to cooperate with the first adjusting member 3 to adjust the inclination of the crossbeam 2. After adjustment, the crossbars 45 and the first fixing member 41 are locked together using the locking assembly.

[0066] Based on any of the above embodiments, the locking assembly includes a transmission screw 44 and two third fixing members 43 threadedly connected thereto. The hinged portions of two crossbars 45 located on the same side of the centerline are connected to the third fixing members 43. The transmission screw 44 passes through the two third fixing members 43. The third fixing members 43 can change their position connected to the transmission screw 44 to change the degree of contraction and expansion of the retractable and expandable structure.

[0067] Please refer to Figure 1 , Figure 6 Four crossbars 45 are provided between the first fixing member 41 and the second fixing member 42 to form a retractable and expandable structure.

[0068] The locking assembly includes a transmission screw 44 and a third fixing member 43 threadedly connected thereto. Specifically, two third fixing members 43 are provided to fix the hinged portions of the crossbars 45 on both sides of the centerline of the first fixing member 41 and the second fixing member 42. By fixing the hinged portions of the crossbars 45 to the third fixing members 43, the degree of contraction and expansion of the second adjusting member 4 is correspondingly changed when the third fixing member 43 moves relative to the transmission screw 44. After adjustment, the threaded connection between the transmission screw 44 and the third fixing member 43 ensures that the crossbars 45 no longer move, maintaining a relatively stable state of the photovoltaic support.

[0069] When the transmission screw 44 and the third fixing member 43 rotate relative to each other, the expansion and contraction of the expandable and contractible structure can be realized, regardless of whether the transmission screw 44 rotates, the third fixing member 43 rotates, or both rotate.

[0070] Based on any of the above embodiments, the locking assembly further includes a locking pin and a locking nut for locking or unlocking the second end of the crossbeam 2, the locking pin passing through the first fixing member 41 and the second end of the crossbeam 2, and the locking nut connected to the locking pin to restrict the rotation of the crossbeam 2 relative to the first fixing member 41.

[0071] When the first fixing member 41 of the second adjusting member 4 is unlocked or locked, the locking pin passes through the first fixing member 41 and the second end of the crossbeam 2. When the locking nut is tightened, the locking pin cannot move, and the first fixing member 41 is locked. When the locking nut is removed or loosened, the locking pin is released, and the second end of the crossbeam 2 can rotate relative to the first fixing member 41 to achieve the adjustment effect.

[0072] Taking one specific embodiment as an example, the locking pin may have a threaded portion and a smooth shaft portion. When the threaded portion is located in the corresponding connecting hole of the first fixing member 41 and the second end of the crossbeam 2, the locking nut locks the first fixing member 41 and the crossbeam 2 relative to each other. When the locking nut and the locking pin are turned so that the smooth shaft portion is located in the corresponding connecting hole of the first fixing member 41 and the second end of the crossbeam 2, the second end of the crossbeam 2 can rotate relative to the second fixing member 42 to achieve the adjustment effect.

[0073] Based on any of the above embodiments, please refer to Figure 1 , Figure 4 , Figure 5 The first adjusting component 3 includes: a first column 31, a second column 32, a spring pin 33, and a limiting hole 321.

[0074] The first column 31 is rotatably connected to the first end of the crossbeam 2. When adjusting the inclination of the crossbeam 2, the first column 31 and the second column 32 can rotate simultaneously relative to the first end of the crossbeam 2.

[0075] The second column 32 is inserted into and rotatably connected to the first column 31 in the installation area 5. When the inclination of the crossbeam 2 is adjusted, the first column 31 and the second column 32 can rotate simultaneously relative to the installation area 5.

[0076] The first column 31 can extend and retract relative to the second column 32 to achieve the effect of adjusting the height of the first end of the crossbeam 2.

[0077] The spring pin 33 is connected to the first column 31 or the second column 32; the limiting hole 321 is provided in the first column 31 or the second column 32, the spring pin 33 extends out of the limiting hole 321 to limit the extension and retraction of the first column 31 relative to the second column 32, or the spring pin 33 retracts into the limiting hole 321 to facilitate the extension and retraction of the first column 31 relative to the second column 32.

[0078] In the above process, the retraction of spring pin 33 into limiting hole 321 specifically means retracting into the first column 31 or into the second column 32.

[0079] Taking one specific implementation as an example, the spring pin 33 is connected to the second column 32. By pressing the spring pin 33, it extends into the second column 32, and pushes the second column 32 to extend and retract relative to the first column 31 to achieve the height adjustment effect. After adjustment, the spring pin 33 extends into the corresponding limiting hole 321 on the first column 31.

[0080] Of course, the spring pin 33 can also be connected to the first column 31, and the limiting hole 321 can be used to set the second column 32, which is not limited to the above specific implementation method.

[0081] In this embodiment, the number of spring pins 33 is not limited; one, two, or more can be set, depending on the actual application.

[0082] Based on any of the above embodiments, please refer to Figure 1 , Figure 4 , Figure 5 A limiting seat 34 is provided inside the first column 31. The limiting seat 34 is an I-shaped seat. Two spring pins 33 are fixedly connected to both ends of the I-shaped seat. The extension and retraction direction of the spring pins 33 is perpendicular to the extension and retraction direction of the first column 31.

[0083] That is, two spring pins 33 are fixed inside the first column 31. By moving the first column 31, the spring pins 33 are inserted into any limiting hole 321 on the second column 32, so as to adjust the length of the first column 31, that is, to adjust the height of the first end of the crossbeam 2. At the same time, by rotating the first column 31 and the second column 32 as a whole, the tilt of the crossbeam 2 can be adjusted.

[0084] Based on any of the above embodiments, multiple sets of limiting holes 321 are evenly distributed along the height direction of the second column 32.

[0085] Taking a specific implementation as an example, a limiting hole 321 can be provided every 50mm in the height direction of the second column 32. The overall height of the first column 31 and the second column 32 can be adjusted by the cooperation between the limiting hole 321 and the spring pin 33.

[0086] The specific size of the limiting hole 321 is adapted to the size of the spring pin 33 to ensure that the spring pin 33 can be reliably locked, thus limiting the telescopic movement of the first column 31.

[0087] Based on any of the above embodiments, the locking component includes a locking member that can change its longitudinal position connected to the first post 31 or the second post 32 to lock or unlock the first post 31 and the second post 32.

[0088] The locking component can be a locking pin, which specifically includes a threaded portion and a smooth shaft portion arranged longitudinally. When the threaded portion is located in the corresponding connecting hole at the first end of the first column 31 and the crossbeam 2, the locking nut locks the first column 31 and the crossbeam 2 relative to each other. When the locking nut and the locking pin are turned so that the smooth shaft portion is located in the corresponding connecting hole at the first end of the first column 31 and the crossbeam 2, the first column 31 and the second column 32 can rotate relative to the first end of the crossbeam 2 to achieve the adjustment effect.

[0089] Similarly, for the second column 32, when the threaded part is located in the corresponding connecting hole between the second column 32 and the mounting area 5, the locking nut locks the second column 32 and the mounting area 5 relative to each other; when the locking nut and locking pin are turned so that the optical axis part is located in the corresponding connecting hole between the second column 32 and the mounting area 5, the first column 31 and the second column 32 can rotate relative to the mounting area 5 to achieve the adjustment effect.

[0090] Based on any of the above embodiments, the first end of the crossbeam 2 is provided with a first hinge seat 6 for rotatably connecting the first adjusting member 3, and the first hinge seat 6 is specifically hinged to the first column 31; the second end of the crossbeam 2 is provided with a second hinge seat 7 for rotatably connecting the second adjusting member 4, and the second hinge seat 7 is specifically hinged to the first fixing member 41.

[0091] Please refer to Figure 1 , Figure 7 The crossbeam 2 has a U-shaped structure, and multiple sets of waist-shaped holes are set in the horizontal direction of the crossbeam 2 for connecting the photovoltaic module 1. This facilitates the adjustment of the installation holes due to installation errors, making the installation more efficient and convenient.

[0092] More specifically, the photovoltaic module 1 is connected to the crossbeam 2 by photovoltaic clamps and fixing bolts to ensure the stability and reliability of the connection.

[0093] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
