Description

Technical Field

[0001] This application relates to the field of new energy technology, and in particular to photovoltaic mounting brackets. Background Technology

[0002] Solar energy, as a clean and renewable energy source, has attracted much attention for its development and utilization. Photovoltaic (PV) systems, with their advantages of sustainability and environmental friendliness, have been widely used globally. In PV systems, the mounting bracket is a key component, providing fixation and support for the solar photovoltaic panels and directly affecting the power generation efficiency and stability of the system.

[0003] Currently, in installation environments with complex and diverse terrains, such as mountains, hills, and uneven ground, traditional bracket mounts lack effective adjustment mechanisms. This makes the installation process extremely difficult, requiring construction workers to spend a significant amount of time and effort on ground leveling, which not only increases construction costs but also extends the project duration. Improper ground preparation can cause the bracket mounts to become unlevel, resulting in deviations in the tilt angle of the photovoltaic panels. This deviation significantly reduces the efficiency of the photovoltaic panels in receiving solar energy, preventing them from reaching their optimal power generation state and severely impacting the overall power generation efficiency of the photovoltaic system.

[0032] Figure 1 A perspective view of a photovoltaic mounting bracket provided in an embodiment of this application; Figure 2 This is a front view of a photovoltaic mounting bracket provided in one embodiment of this application; Figure 3 This is a side view of a photovoltaic mounting bracket provided in one embodiment of this application.

[0033] See Figures 1 to 3An embodiment of this application provides a photovoltaic mounting bracket, including a lifting base 100, a mounting base 200, an angle adjustment mechanism 300, and multiple lifting legs 400. The mounting base 200 is rotatably mounted on the upper side of the lifting base 100. The angle adjustment mechanism 300 is mounted on the lifting base 100 and connected to the mounting base 200, and is used to drive the mounting base 200 to rotate vertically. Multiple lifting legs 400 are all mounted on the lower side of the lifting base 100, and the multiple lifting legs 400 are configured to have independently adjustable lengths.

[0034] In this embodiment, the mounting base 200 is used to mount a photovoltaic panel. The angle of the mounting base 200 affects the angle of the photovoltaic panel. Taking the mounting base 200 as a plate-like structure, with the photovoltaic panel fixed parallel to the upper side of the mounting base 200 as an example, the plane of the mounting base 200 is parallel to the plane of the photovoltaic panel. Therefore, the mounting base 200 needs to be adjusted to a suitable angle to ensure that the photovoltaic panel has a high power generation efficiency. The mounting base 200 is connected to the lifting seat 100 through an angle adjustment mechanism 300. The angle of the mounting base 200 can be adjusted through the angle adjustment mechanism 300, thereby adjusting the angle of the photovoltaic panel.

[0035] In this embodiment, the lifting seat 100 can adopt a plate-like structure, and in order to ensure stability and facilitate the angle adjustment of the mounting base 200 and the photovoltaic panel, the lifting seat 100 is usually set to horizontal.

[0036] Due to the variable outdoor environment, there is usually no level installation surface. The ground needs to be leveled before the photovoltaic mounting bracket can be placed on it. Manual processing is difficult, time-consuming, and labor-intensive, which is not conducive to improving installation efficiency and makes it difficult to ensure the stability of the photovoltaic mounting bracket. The 100% levelness of the lifting platform also makes it difficult to adjust the photovoltaic panels to the appropriate angle, which is detrimental to the power generation efficiency of the photovoltaic panels.

[0037] In this application, multiple lifting legs 400 are provided below the mounting base 200. These multiple lifting legs 400 provide stable support for the mounting base 200. Furthermore, the length of each lifting leg 400 is independently adjustable. Therefore, each lifting leg 400 can be independently adjusted according to its ground position, thereby adjusting the lifting base 100 to a suitable angle, for example, adjusting it to a horizontal position. This ensures that the lifting base 100 provides good support for the mounting base 200, facilitating angle adjustment of the mounting base 200 via the angle adjustment mechanism 300, and allowing the photovoltaic panels on the mounting base 200 to be adjusted to a suitable angle.

[0038] The photovoltaic mounting bracket in this embodiment has both leg lifting and angle adjustment functions, making it more convenient and flexible to use, with better applicability. It can effectively improve the installation efficiency and quality of photovoltaic panels, and help reduce costs and improve energy utilization.

[0039] Figure 4 This is a schematic diagram of the lifting support leg in a photovoltaic mounting bracket provided in an embodiment of this application.

[0040] Combination Figure 2 and Figure 4 In some embodiments, the lifting outrigger 400 includes a bottom support plate 410, a sliding guide mechanism 420, and a lifting drive mechanism 430. The bottom support plate 410 is spaced apart below the lifting seat 100. The sliding guide mechanism 420 includes a first sliding member 421 and a second sliding member 422. The first sliding member 421 is fixedly connected to the lifting seat 100 and slidably connected to the second sliding member 422 in the vertical direction. The second sliding member 422 is fixedly connected to the bottom support plate 410. The lifting drive mechanism 430 includes an adjusting screw 431, an adjusting nut 432, a first rotating shaft 433, and a connecting rod assembly 434. The adjusting screw 431 is horizontally arranged and rotatably connected to the first sliding member 421 or the second sliding member 422. The adjusting nut 432 is threadedly connected to the adjusting screw 431. The first rotating shaft 433 is horizontally arranged and fixedly connected to the adjusting nut 432. The connecting rod assembly 434 includes a first connecting rod 4341 and a second connecting rod 4342. One end of the first connecting rod 4341 is rotatably connected to the bottom support plate 410, and the other end is rotatably connected to the first rotating shaft 433. One end of the second connecting rod 4342 is rotatably connected to the lifting seat 100, and the other end is rotatably connected to the first rotating shaft 433.

[0041] In this embodiment, bottom support plates 410 are spaced apart below the lifting seat 100 to contact the ground and provide support. The bottom support plates 410 distribute the weight of the photovoltaic mounting bracket, ensuring its stability. The sliding guide mechanism 420 includes a first sliding member 421 and a second sliding member 422. The first sliding member 421 is fixedly connected to the lifting seat 100 and slidably connected to the second sliding member 422 in the vertical direction. The second sliding member 422 is fixedly connected to the bottom support plate 410. The function of the sliding guide mechanism 420 is to ensure that the lifting outrigger 400 can move smoothly when adjusting its length, avoiding swaying or tilting. The lifting drive mechanism 430 includes an adjusting screw 431, an adjusting nut 432, a first rotating shaft 433, and a connecting rod assembly 434. The adjusting screw 431 is horizontally positioned and rotatably connected to either the first sliding member 421 or the second sliding member 422. The adjusting nut 432 is threadedly connected to the adjusting screw 431. The first rotating shaft 433 is horizontally positioned and fixedly connected to the adjusting nut 432. The linkage assembly 434 includes a first linkage 4341 and a second linkage 4342. One end of the first linkage 4341 is rotatably connected to the bottom support plate 410, and the other end is rotatably connected to the first rotating shaft 433. One end of the second linkage 4342 is rotatably connected to the lifting seat 100, and the other end is rotatably connected to the first rotating shaft 433.

[0042] The lifting drive mechanism 430 adjusts the length of the lifting outrigger 400 by rotating the adjusting screw 431, thereby adapting to different ground height differences. Specifically, rotating the adjusting screw 431 drives the adjusting nut 432 to move horizontally. The adjusting nut 432 horizontally drives the first rotating shaft 433 to move horizontally. At this time, the ends of the first connecting rod 4341 and the second connecting rod 4342 connected to the first rotating shaft 433 move closer to or further away from the first slider 320 or the second slider 340, causing the angle between the first connecting rod 4341 and the second connecting rod 4342 and the horizontal plane to change. When the first connecting rod 4341 and the second connecting rod 4342 are vertical, the total height of the first connecting rod 4341 and the second connecting rod 4342 in the vertical direction is the maximum, and the length of the lifting outrigger 400 is the maximum. When the angle between the first connecting rod 4341 and the second connecting rod 4342 and the horizontal plane gradually decreases, the total height of the first connecting rod 4341 and the second connecting rod 4342 in the vertical direction gradually decreases, and the length of the lifting outrigger 400 decreases.

[0043] By adjusting the screw 431 and the connecting rod assembly 434, the lifting outrigger 400 can be independently adjusted in length, allowing the photovoltaic mounting bracket to remain level on uneven ground. This greatly reduces installation difficulty, especially in complex terrains such as mountains and hills, eliminating the need for workers to perform additional ground leveling.

[0044] Furthermore, the sliding guide mechanism 420 ensures the smooth movement of the lifting outrigger 400 during adjustment, preventing swaying or tilting of the support during adjustment and enhancing the overall stability of the support. The design of the lifting drive mechanism 430 makes the length adjustment of the lifting outrigger 400 simple; construction personnel only need to rotate the adjusting screw 431 to extend or retract the lifting outrigger 400, without the need for complicated tools or operating procedures.

[0045] Compared to using vertically installed telescopic structures or screw-nut lifting drive mechanisms 430 as outriggers, the lifting outrigger 400 in this embodiment has the following advantages: More efficient force transmission. The horizontally positioned adjusting screw 431 drives the adjusting nut 432 to translate via a thread, linking with the symmetrical connecting rod assemblies 434 on both sides to form a bidirectional mechanical transmission, converting horizontal movement into vertical lifting. This avoids the torque concentration problem associated with single-point driving of a vertical screw, significantly improving adjustment accuracy and smoothness of movement. In the connecting rod assembly 434, the first connecting rod 4341 and the second connecting rod 4342 are respectively connected to the bottom support plate 410 and the lifting seat 100, forming a triangular support structure. During adjustment, the bidirectional force counteracts lateral offset forces. Combined with the vertical limit of the sliding guide mechanism 420, this effectively prevents the outrigger from tilting or swaying, ensuring stable and reliable lifting. Therefore, it has better anti-offset performance and stability. Furthermore, the horizontal screw layout reduces vertical space occupation, facilitating compact design. Simultaneously, the symmetrical distribution of multiple connecting rods ensures that the load is evenly distributed to each support point, reducing local stress concentration and extending the service life of the mechanism. In addition, the linear drive characteristics of the horizontal screw, combined with multi-link linkage, can achieve precise control of the outrigger length by finely adjusting the screw rotation angle without compromising the flatness of the ground. This is especially suitable for ground with large slopes or uneven surfaces, ensuring that the base can be quickly leveled.

[0046] In some embodiments, the lifting drive mechanism 430 includes two first rotating shafts 433 and two connecting rod assemblies 434. The two connecting rod assemblies 434 are respectively placed on both sides of the adjusting nut 432 and are respectively connected to the adjusting nut 432 through a first rotating shaft 433.

[0047] Specifically, a first rotating shaft 433 is fixedly connected to each side of the adjusting nut 432. Each first rotating shaft 433 is rotatably connected to a first connecting rod 4341 and a second connecting rod 4342 of a connecting rod assembly 434. The other end of the first connecting rod 4341 is rotatably connected to the bottom support plate 410, and the other end of the second connecting rod 4342 is rotatably connected to the lifting seat 100. Through this symmetrical arrangement, the horizontal movement of the adjusting nut 432 can synchronously drive the connecting rod assemblies 434 on both sides, causing relative movement between the bottom support plate 410 and the lifting seat 100, thereby realizing the synchronous extension and retraction of the lifting outrigger 400. This design of the double connecting rod assembly 434 not only enhances the stability of the lifting drive mechanism 430, but also ensures the uniformity of force on the outrigger during the lifting process.

[0048] In some embodiments, the lifting drive mechanism 430 further includes a handwheel 435, which is coaxial with the adjusting screw 431 and fixedly connected to one end of the adjusting screw 431.

[0049] The addition of a handwheel 435 at the end of the adjusting screw 431 significantly improves ease of operation. Construction workers can directly drive the adjusting screw 431 by rotating the handwheel 435 without additional tools, thus achieving precise adjustment of the outrigger length. At the same time, the torque amplification effect and anti-slip design of the handwheel 435 enhance adjustment accuracy and operational comfort, reducing operator fatigue. The rigid connection ensures efficient transmission of driving force, avoids the risk of adjustment failure, and improves the overall structural reliability.

[0050] Alternatively, the handwheel 435 can be detachably mounted to the end of the adjusting screw 431, or the handwheel 435 can be a folding handwheel 435, thereby saving space.

[0051] Optionally, the handwheel 435 is equipped with scale markings or a digital display to improve adjustment accuracy.

[0052] The above embodiment uses a manual adjustment method, while in other embodiments, an electric lifting drive mechanism 430 can also be used. For example, the lifting outrigger 400 can be automatically adjusted by rotating the adjusting screw 431 driven by a motor.

[0053] Of course, in some other embodiments, the adjustment function of the lifting outrigger 400 can also be achieved in other ways. For example, a worm gear mechanism can be used, where the worm drives the worm wheel to rotate, thereby driving the outrigger to rise and fall smoothly. This mechanism has a self-locking function to prevent the outrigger from retracting after adjustment. Alternatively, a rack and pinion mechanism can be used, where the gear is driven to rotate by a motor or manually, causing the rack to move up and down, achieving linear lifting and lowering of the outrigger. This is suitable for scenarios requiring rapid adjustment. All these solutions can achieve the lifting and lowering function of the outrigger, and the appropriate lifting drive mechanism 430 can be selected according to the specific application scenario.

[0054] In some embodiments, the first sliding member 421 includes a fixing part 4211 and a first sliding part 4212. The fixing part 4211 is fixedly connected to the lifting seat 100 and the first sliding part 4212 respectively. The first sliding part 4212 is provided with a sliding hole that extends vertically through the first sliding part 4212. The second sliding member 422 includes a second sliding part 4221, which is slidably disposed in the sliding hole. The bottom end of the second sliding part 4221 is fixedly connected to the bottom support plate 410.

[0055] In this embodiment, the fixing part 4211 of the first sliding member 421 is rigidly connected to the lifting seat 100, and combined with the fixed connection between the second sliding part 4221 and the bottom support plate 410, a stable support structure is formed, enhancing the overall anti-displacement capability and load-bearing performance of the lifting outrigger 400. The second sliding member 422 is adapted to the sliding hole, ensuring that the second sliding part 4221 slides smoothly in the vertical direction within the sliding hole, while limiting its horizontal displacement. Through the cooperation between the sliding hole and the second sliding part 4221, precise vertical guidance of the lifting outrigger 400 is achieved, avoiding shaking or displacement during the adjustment process and significantly improving the adjustment accuracy.

[0056] Optionally, the first sliding portion 4212 of the first sliding member 421 is a vertically oriented rectangular columnar structure with a rectangular sliding hole inside, and the second sliding member 422 is a rectangular second sliding portion 4221 that matches the sliding hole. The rectangular structure provides a larger contact area through planar contact, which enhances the resistance to lateral displacement of the sliding guide mechanism 420, while also facilitating processing and installation and reducing manufacturing costs.

[0057] The first sliding part 4212 of the first sliding member 421 can also be a vertical cylindrical structure with a cylindrical sliding hole inside. The second sliding member 422 is a cylindrical second sliding part 4221 that matches the sliding hole. This structure can evenly distribute the force on the sliding contact surface, reduce local wear, and achieve 360° sliding guidance without dead angles, avoiding jamming problems caused by directional deviation.

[0058] In some embodiments, the second slider 422 further includes a limiting portion 4222, which is located above the first slider 4212 and is fixedly connected to the second slider 4221. The horizontal cross-sectional area of ​​the limiting portion 4222 is greater than the horizontal cross-sectional area of ​​the sliding hole.

[0059] The horizontal cross-sectional area of ​​the limiting part 4222 is larger than that of the sliding hole, allowing the limiting part 4222 to cover the upper opening of the sliding hole, forming a mechanical limiting structure. When the second sliding part 4221 slides within the sliding hole, the limiting part 4222 contacts the upper end of the first sliding part 4212, preventing the second sliding part 4221 from continuing to move upward, thereby limiting the maximum height of the lifting leg 400 and preventing damage to the mechanism or instability of the support due to excessive lifting. The mechanical limiting function of the limiting part 4222 is simple and reliable, requiring no reliance on a complex external control system, further enhancing the applicability and ease of operation of the device.

[0060] Optionally, the contact surface between the limiting part 4222 and the first sliding part 4212 is provided with an elastic buffer pad (such as rubber or spring) to absorb the impact force during the lifting process, reduce vibration and noise, and extend the service life of the mechanism.

[0061] In some embodiments, the first sliding member 421 includes two first sliding portions 4212, which are respectively disposed on both sides of the fixed portion 4211. The fixed portion 4211 is fixedly connected to the lifting seat 100 to ensure the rigidity of the overall structure. The sliding guide mechanism 420 includes two second sliding members 422, and the second sliding portions 4221 of the two second sliding members 422 are respectively connected to the two first sliding portions 4212 in a one-to-one correspondence. Each second sliding portion 4221 is slidably inserted into the sliding hole of the corresponding first sliding portion 4212, and the bottom end of the second sliding portion 4221 is fixedly connected to the bottom support plate 410.

[0062] Through the symmetrical arrangement of the first sliding part 4212 and the second sliding part 4221 on both sides, the sliding guide mechanism 420 of the lifting outrigger 400 achieves uniform force distribution, avoiding the problem of uneven load caused by unilateral force, and significantly improving the stability and load-bearing capacity during the adjustment process. The two second sliding parts 4221 are connected one-to-one with the two first sliding parts 4212, ensuring the synchronicity of the lifting outrigger 400 during the adjustment process and avoiding the problem of bracket tilting or swaying caused by asynchrony. The structure of the double-sided sliding guide mechanism 420 enhances the overall anti-offset capability, maintaining the stability of the bracket even under complex terrain or dynamic loads, ensuring that the photovoltaic panel is always at the optimal power generation angle. Furthermore, the double-sided sliding guide mechanism 420 simplifies the installation process and improves construction efficiency.

[0063] Optionally, the dual-sided sliding guide mechanism 420 is provided with a lubrication structure, such as a lubrication groove or coating, to further reduce sliding friction resistance and extend the service life of the mechanism.

[0064] Figure 5 This is a schematic diagram of the angle adjustment mechanism in a photovoltaic mounting bracket provided in an embodiment of this application.

[0065] Combination Figure 5 In some embodiments, the angle adjustment mechanism 300 includes a telescopic drive 310 and a first slider 320. The telescopic drive 310 is vertically mounted on the lifting base 100, and its drive end is rotatably connected to the first slider 320. The rotation axis of the first slider 320 is parallel to the rotation axis of the mounting base 200. The first slider 320 is slidably connected to the mounting base 200, and the relative sliding direction between the first slider 320 and the mounting base 200 is perpendicular to the rotation axis of the mounting base 200. When the telescopic drive 310 extends or retracts, the drive end drives the first slider 320 to rise or fall, and the first slider 320 slides relative to the mounting base 200 in a direction perpendicular to the rotation axis of the mounting base 200, thereby pushing the mounting base 200 to rotate around its rotation axis, realizing the angle adjustment of the mounting base 200. This converts linear motion into rotational motion, ensuring that the mounting base 200 can be accurately adjusted to the required angle.

[0066] The rotational connection between the telescopic drive component 310 and the first slider 320 ensures efficient transmission of driving force, while the sliding connection between the first slider 320 and the mounting base 200 converts linear motion into rotational motion, enabling precise adjustment of the mounting base 200 angle. The rotation axis of the first slider 320 is parallel to the rotation axis of the mounting base 200, and the sliding direction is perpendicular to the rotation axis, avoiding lateral offset during adjustment and ensuring the smoothness and accuracy of angle adjustment. The vertical installation of the telescopic drive component 310 simplifies the structural layout, reduces space occupation, and enhances the stability and load-bearing capacity of the angle adjustment mechanism 300. Furthermore, this angle adjustment mechanism 300 is easy to operate, can quickly respond to adjustment needs, and is suitable for photovoltaic panel installation in complex terrain.

[0067] Optionally, the telescopic drive component 310 can be an electric push rod or a lead screw and nut mechanism, etc. Preferably, the telescopic drive component 310 is an electric push rod, and further, the electric push rod is electrically connected to the photovoltaic panel, and can be powered by the electrical energy generated by the photovoltaic panel.

[0068] Optionally, a linear guide rail is provided on the lower side of the mounting base 200, and a slider assembly matching the guide rail is mounted on the first slider 320. The guide rail is arranged in a direction perpendicular to the rotation axis of the mounting base 200, and the first slider 320 slides on the guide rail via the slider assembly. Precise guidance from the guide rail ensures that the first slider 320 remains stable during sliding, avoiding deviation or jamming. Alternatively, a T-slot is formed on the lower side of the mounting base 200, and a T-shaped slider matching the T-slot is provided on the first slider 320. The T-shaped slider is embedded in the T-slot and slides along the direction of the slot. The fit between the T-slot and the slider provides a larger contact area, enhancing the stability and anti-deviation capability of the sliding connection.

[0069] In some embodiments, the angle adjustment mechanism 300 further includes a driven telescopic mechanism 330 and a second slider 340. The driven telescopic mechanism 330 includes a telescopic base 331 and a telescopic rod 332. The telescopic base 331 is fixedly disposed on the upper side of the lifting seat 100, and the telescopic rod 332 is slidably connected to the lifting seat 100 in the vertical direction. The second slider 340 is rotatably connected to the top end of the telescopic rod 332 and slidably connected to the mounting base 200. The rotation axis of the second slider 340 is parallel to the rotation axis of the mounting base 200, and the relative sliding direction between the second slider 340 and the mounting base 200 is perpendicular to the rotation axis of the mounting base 200. When the telescopic rod 332 slides in the vertical direction, it drives the second slider 340 to move. The second slider 340, through its slidable connection with the mounting base 200, pushes the mounting base 200 to rotate around its rotation axis, thereby realizing the angle adjustment of the mounting base 200.

[0070] In this embodiment, the telescopic base 331 of the driven telescopic mechanism 330 is fixedly mounted on the upper side of the lifting seat 100, and the telescopic rod 332 slides vertically, ensuring uniform force distribution during angle adjustment and avoiding eccentric load problems caused by unilateral force distribution. The rotational connection between the second slider 340 and the telescopic rod 332, as well as the sliding connection with the mounting base 200, converts the linear motion of the telescopic rod 332 into the rotational motion of the mounting base 200, achieving precise adjustment of the angle of the mounting base 200. The synergistic effect of the driven telescopic mechanism 330 and the second slider 340 enhances the overall stability and load-bearing capacity of the angle adjustment mechanism 300, making it suitable for photovoltaic panel installation in complex terrain.

[0071] Of course, the photovoltaic mounting bracket can also achieve angle adjustment without the driven telescopic mechanism 330 and the second slider 340.

[0072] In some embodiments, the rotating mechanism 350 includes a rotating seat 351 and a connecting block 352. The bottom end of the rotating seat 351 is fixedly disposed on the upper side of the lifting seat 100, and a groove is formed at the top end. The connecting block 352 is rotatably disposed in the groove via a rotating shaft and is fixedly connected to the mounting seat 200. The rotation axes of the connecting blocks 352 of the multiple rotating mechanisms 350 coincide, causing the mounting seat 200 to rotate around the same axis. When the mounting seat 200 needs to adjust its angle, the connecting block 352 rotates around the rotating shaft in the groove of the rotating seat 351. In this embodiment, the rigid fixation of the rotating seat 351 to the lifting seat 100 enhances the stability of the overall structure, maintaining the balance of the mounting seat 200 even under dynamic loads or complex terrain. The cooperation between the groove and the rotating shaft makes angle adjustment smoother, while improving the durability and load-bearing capacity of the mechanism.
