Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a quick-install bearing connection structure and a photovoltaic support system. Background Technology

[0002] Foldable mobile photovoltaic (PV) brackets are widely used in temporary power supply, tidal flats, and agricultural greenhouses due to their flexibility. In these bracket systems, the connector between the support tube and the connecting rod is the core component determining its unfolding reliability, folding smoothness, and installation efficiency. Currently, this connection part mostly uses a traditional structure, which has the following obvious drawbacks:

[0003] Firstly, in terms of the connection structure, a split-type metal bushing and bolt fastening method is commonly used. During on-site installation, this structure requires aligning multiple parts and performing tedious tightening operations using wrenches and other tools, resulting in numerous installation steps and low efficiency. Furthermore, the connection strength between the metal bushing and the support pipe is limited. Under long-term wind loads and repeated expansion and contraction stress, the connection points are prone to loosening, causing the entire support structure to sway and lack stability.

[0004] Secondly, due to the limitations of the aforementioned connection structure, the overall support system suffers from low modularity and poor scalability. Assembling multiple units to install more photovoltaic modules often requires complex connectors and additional installation steps, hindering rapid and flexible large-scale deployment.

[0037] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1

[0039] Please see the appendix Figure 1-7 As shown, this embodiment provides a quick-connect bearing connection structure 1, including a first bearing side shaft 11 and a second bearing side shaft 12. The first bearing side shaft 11 includes a first shaft body 111 and a first locking mechanism 112 disposed thereon. The second bearing side shaft 12 includes a second shaft body 121 and a second locking mechanism 122 disposed thereon. The first shaft body 111 has a first shaped groove extending through it axially, and the second shaft body 121 has a second shaped groove 123 extending through it axially. The first locking mechanism 112 and the second locking mechanism 122 can be aligned with each other and locked together by rotation, so that the first shaped groove and the second shaped groove 123 together form a channel for the connecting rod 3 to pass through. A limiting slot 23 for the locking mechanism to be inserted is provided on the folding support unit 2.

[0040] Installation steps: Refer to the attached document. Figure 3 As shown, the first snap-fit ​​mechanism 112 of the first bearing side shaft 11 is aligned with the limiting slot 23 of the folding support unit 2 and pushed in, and the second snap-fit ​​mechanism 122 of the second bearing side shaft 12 is aligned with the limiting slot 23 and pushed in. Then, the first bearing side shaft 11 and the second bearing side shaft 12 are rotated relative to each other, so that the two bearing side shafts are locked together by the cooperation of the first snap-fit ​​mechanism 112 and the second snap-fit ​​mechanism 122. Finally, the connecting rod 3 is inserted into the groove, and finally the fastener (pin) is put in, thus completing the connection between the folding support unit 2 and the connecting rod 3.

[0041] The quick-connect bearing connection structure 1 in this embodiment, by setting a first bearing side shaft 11 and a second bearing side shaft 12 with a specific locking mechanism, realizes the quick connection between the folding support unit 2 and the connecting rod 3, as well as the quick rotation and locking between the two shafts of the quick-connect bearing connection structure 1. This greatly simplifies the installation process, and the initial locking can be completed without tools, thus improving the installation efficiency. In addition, the quick-connect bearing connection structure 1 can ensure that the connecting rod 3 will not deflect and will always maintain a unidirectional direction. It will not rotate due to the unfolding of the photovoltaic bracket, thus avoiding the friction caused by rotation between the connecting rod 3 and the folding support unit 2, ensuring the reliability and directional consistency of the connection.

[0042] In this embodiment, the shape of the first groove is any one of square, polygon, or circle; the shape of the second groove 123 is any one of square, polygon, or circle; the first groove and the second groove 123 have the same shape. This quick-install bearing connection structure 1 is not limited to connecting rods with specific cross-sections, but can adapt to the needs of different application scenarios, improving the versatility and market application potential of the quick-install bearing connection structure 1. Preferably, the shape of the first groove is a first square groove; the second groove 123 is a second square groove; when the first bearing side shaft 11 and the second bearing side shaft 12 are clamped, the first square groove and the second groove 123 overlap, forming a slot for the connecting rod 3 to pass through. Existing connecting rods 3 are mostly square connecting rods. The torsional resistance of square connecting rods can effectively prevent the connecting rod 3 from rotating within the square groove, ensuring the stability of the support structure after deployment, which is a key technical feature for achieving the function of preventing the connecting rod 3 from deflecting. Furthermore, during installation, as long as the first bearing side shaft 11 and the second bearing side shaft 12 are roughly aligned according to the shape of the square groove, it is easy to align the two clamping mechanisms, improving installation efficiency.

[0043] As attached Figure 4-7 As shown, the quick-install bearing connection structure 1 also includes a bearing central shaft 13 for cooperating with the first bearing side shaft 11 and the second bearing side shaft 12. The bearing central shaft 13 includes a central shaft body 131, a third locking mechanism 132 and a fourth locking mechanism 133 respectively disposed on both sides of the central shaft body 131; the central shaft body 131 has a third shaped groove 134 for inserting a connecting rod through it along the axial direction; the third locking mechanism 132 is used to cooperate with the first locking mechanism 112 and has the same structure as the second locking mechanism 122; the fourth locking mechanism 133 is used to cooperate with the second locking mechanism 122 and has the same structure as the first locking mechanism 112. The bearing central shaft 13 can cover the connection requirements of different positions (adjacent folding supports) in the support system, realizing the modularity and high adaptability of the design. In this embodiment, if only the first bearing side shaft 11 and the second bearing side shaft 12 cooperate with the quick-install bearing connection structure 1, then it constitutes an end bearing (as shown in the attached figure). Figure 1-3 (As shown). If the quick-connect bearing connection structure 1 includes the first bearing side shaft 11, the bearing central shaft 13, and the second bearing side shaft 12, then it constitutes a central bearing (as shown in the attached diagram). Figure 4-7 (As shown). This greatly expands the application scenarios of the quick-install bearing connection structure 1.

[0044] Installation steps: Refer to the attached document. Figure 7As shown (adjacent folding support units 2 and connecting rods 3 are installed using a central bearing), the bearing central shaft 13 is aligned with the limiting slots 23 of the support tubes on the left and right sides and pushed in. The first locking mechanism 112 of the first bearing side shaft 11 is aligned with the limiting slots 23 of the folding support unit 2 and pushed in. The second locking mechanism 122 of the second bearing side shaft 12 is aligned with the limiting slots 23 and pushed in. Then, the first bearing side shaft 11 and the second bearing side shaft 12 are rotated relative to each other, so that the third locking mechanism 132 is locked with the first locking mechanism 112, the fourth locking mechanism 133 and the second locking mechanism 122 are locked. Finally, the connecting rod 3 is inserted into the groove, and finally the fastener (pin) is inserted to complete the connection.

[0045] Reference Appendix Figure 2 As shown, the first locking mechanism 112 includes a plurality of first L-shaped hooks 1121 evenly arranged around the periphery of the first shaped groove, and a first L-shaped hook groove 1122 is formed between adjacent first L-shaped hooks 1121 for a second L-shaped hook 1221 to engage with; the second locking mechanism 122 includes a plurality of second L-shaped hooks 1221 evenly arranged around the periphery of the second shaped groove 123, and a second L-shaped hook groove 1222 is formed between adjacent second L-shaped hooks 1221 for a first L-shaped hook 1121 to engage with. The first L-shaped hooks are adapted to the second L-shaped hook grooves, and the second L-shaped hooks are adapted to the first L-shaped hook grooves. The first L-shaped hook 1121 includes a first main body connecting part 11211 and a first hook part 11212; one end of the first main body connecting part 11211 is vertically fixedly connected to the first shaft 111, and the other end is vertically fixedly connected to the first hook part 11212; the second L-shaped hook 1221 includes a second main body connecting part 12211 and a second hook part 12212; one end of the second main body connecting part 12211 is vertically fixedly connected to the second shaft 121, and the other end is vertically fixedly connected to the second hook part 12212. In this embodiment, the locking mechanism consists of L-shaped hook grooves that cooperate with each other. This design creates a simple and efficient mechanical interlocking mechanism. The L-shaped hook can be firmly locked by simply inserting it into the L-shaped hook groove and then rotating it. It is intuitive and easy to operate. When the connecting rod 3 is inserted into the L-shaped groove, the square connecting rod and the square groove give the structure itself self-locking properties, effectively resisting separation by external forces and ensuring the stability of the connection.

[0046] In this embodiment, the first shaft 111 and the second shaft 121 are circular shafts. The first shaft 111 has a through hole 114 for fastener insertion, and the through hole 114 is diametrically open along the first shaft 111. The second shaft 121 has a through hole 124 for fastener insertion, and the through hole 124 is diametrically open along the second shaft 121. When the connecting rod 3 is inserted into the square slot, the quick-install bearing connection structure 1 can be fixed. The added through hole design is used to insert pins or fasteners, which is a secondary safety measure on the basis of quick snap-fit. It can prevent the quick-install bearing connection structure 1 from loosening under long-term vibration or accidental impact, greatly improving the safety and reliability of the entire support system, and achieving a combination of quick installation and foolproof protection.

[0047] In this embodiment, the central shaft 131 has a third through hole 135 for fastener insertion, allowing it to be finally fixed by a pin. This ensures that the connection points involving the bearing central shaft 13 also have the highest safety level, maintaining consistent reliability standards for all critical connection points in the entire support system.

[0048] In this embodiment, to improve economic efficiency, the quick-release bearing connection structure 1 is a plastic quick-release bearing connection structure 1. During the repeated unfolding and retraction of the photovoltaic support system, slight friction will occur between the quick-release bearing connection structure 1 and the connecting rod 3 and support tube. Metal-to-metal friction can easily produce sharp squeaking noises and requires regular maintenance, while the combination of plastic and metal enables quiet and smooth operation, improving the user experience and reducing maintenance needs due to friction and wear. In addition, the plastic quick-release bearing connection structure 1 can be molded in a large-scale, high-precision manner in one go using injection molding, and its production efficiency is far higher than that of machining, casting, and subsequent surface treatment (such as rust prevention) of metal parts; this can significantly reduce the production cost of individual parts, and for the entire photovoltaic support system containing multiple quick-release bearing components, the cost advantage is extremely obvious. Furthermore, the plastic quick-release bearing connection structure 1 also has the advantages of avoiding rust, reducing the overall weight of the system, and reducing transportation costs.

[0049] Preferably, the plastic is a mixture of nylon and glass fiber. While pure nylon is tough, it lacks rigidity and dimensional stability. Adding glass fiber creates glass fiber reinforced nylon, which significantly improves strength, toughness, rigidity, stability, and heat resistance.

[0050] Preferably, the quick-release bearing component 1 can also be a UPE material quick-release bearing component 1.

[0051] The quick-install bearing connection structure 1 in this embodiment successfully combines convenience, reliability, economy, and versatility. It is the core key technology for achieving rapid deployment, stable operation, and low-cost maintenance in the entire folding photovoltaic support system, and brings the following significant and beneficial technical effects:

[0052] 1. Installation is extremely convenient and efficiency is significantly improved: The quick-assembly bearing connection structure 1 can be pre-assembled on the folding support unit 2 and connecting rod 3 by a few simple actions of "aligning-pushing-rotating". No tools are required, realizing the replacement of power tools by manpower, greatly shortening the on-site installation time and reducing labor intensity.

[0053] 2. Reliable connection, ensuring system stability: The L-shaped hook's rotational interlocking mechanism provides a strong initial connection force, while subsequent fastener fixation provides double protection. This design ensures that the connection point will not loosen, and the square groove effectively prevents the linkage 3 from rotating, thereby ensuring the structural stability and angular accuracy (such as the critical 30° tilt angle) of the entire photovoltaic support array after deployment.

[0054] 3. Modular design, high versatility, and low cost: By combining basic units (two bearing side shafts) and expansion units (bearing central shaft 13), it can be flexibly configured into end bearings and central bearings to meet the connection requirements of different positions in the support system. This modular and universal design reduces the types of parts, simplifies the supply chain, and achieves the goal of cost reduction.

[0055] 4. Easy to maintain and disassemble: If a bearing shaft is damaged, it can be disassembled and replaced simply by pulling out the fastener and rotating it in the opposite direction. If a single part is damaged, only the corresponding part needs to be replaced, which greatly reduces the later maintenance costs and time.

[0056] Example 2

[0057] Reference Appendix Figure 8-11 As shown, this embodiment provides a foldable and movable photovoltaic support system, including at least one movable component mounting platform 100 (attached). Figure 8-11This illustration shows a foldable, movable photovoltaic support system with four component mounting platforms 100. Each mounting platform 100 includes two opposing folding support units 2, multiple connecting rods 3, a front leg assembly 4, and a rear leg assembly 5. The mounting platform 100 has an unfolded state and a folded state achieved by unfolding and retracting the folding support units 2. Each folding support unit 2 includes a first support tube 21 and a second support tube 22 that are cross-hinged at a central hinge point, specifically by rivets. The multiple connecting rods 3 are used to connect the two folding supports in parallel. Unit 2, the two ends of the connecting rod 3 are fixedly connected to the ends of the first support tube 21 or the second support tube 22 through the quick-connect bearing connection structure 1 (refer to embodiment 1); the first ends of the two first support tubes 21 are connected through the first connecting rod 31; the front leg assembly 4 is fixedly connected to the first end of the first connecting rod 31, and the rear leg assembly 5 is fitted with a linear bearing 6 in the middle, and the linear bearing 6 is fixedly connected to the second end of the first connecting rod 31. This ingeniously realizes the stable support and smooth unfolding / retracting movement of the system, which is the basis for the flexible movement and reliable operation of the entire system.

[0058] The foldable movable photovoltaic support system of this embodiment is an innovative photovoltaic support system that integrates convenience, reliability, versatility, efficiency, and scalability. It consists of two foldable support units 2 connected by a connecting rod 3 to form a stable component installation platform 100. The number of component installation platforms 100 can be adaptively adjusted as needed, thus enabling the installation of different numbers of photovoltaic components. On-site, the entire system can be moved to the ideal position using the front and rear leg components 5. Subsequently, the panels of the entire system are unfolded and fixed through the cooperation of multiple foldable support units 2 and quick-release bearing connection structure 1. Due to the high degree of pre-assembly of the entire foldable movable photovoltaic support system, installation time is greatly saved.

[0059] In this embodiment, refer to the appendix Figure 9As shown, the first ends of the two second support tubes 22 are connected by the second connecting rod 32; the second ends of the two first support tubes 21 are connected by the third connecting rod 33; the second ends of the two second support tubes 22 are connected by the fourth connecting rod 34; at least two component support bars 7 are assembled between the second connecting rod 32 and the fourth connecting rod 34, and the component support bars 7 are infinitely adjustable in length direction with the second connecting rod 32 and the fourth connecting rod 34 through the quick-release bearing connection structure 1. This embodies the parallel frame structure of the four connecting rods 3, forming a stable and reliable photovoltaic module support skeleton. The infinitely adjustable function of the component support bars 7 brings extremely high installation flexibility, enabling the photovoltaic bracket system to perfectly adapt to photovoltaic modules of various sizes and specifications, greatly improving the product's versatility and market adaptability. Simultaneously, the stable geometric structure formed by the four connecting rods 3 and the two folding support units 2, the locking of the connecting rods 3 by the quick-release bearing connection structure 1, the control of the posture of the rear legs 51 by the linear bearing 6, and the final fixation of the fasteners (pins) jointly ensure that the bracket is extremely stable and reliable after deployment, capable of withstanding the test of complex outdoor environments.

[0060] In this embodiment, the component support strip 7 is provided with a plurality of mounting holes 71 for installing photovoltaic modules of different sizes. This design allows installers to flexibly fix the modules according to the holes on the module frame, making the installation process more convenient and precise.

[0061] In this embodiment, the second support tube 22, two second connecting rods 32, a fourth connecting rod 34, and two component support bars 7 are assembled into a photovoltaic module mounting plane through six quick-release bearing connection structures 1.

[0062] In this embodiment, the front leg assembly 4 includes a front leg 41 and a front caster wheel 42; the rear leg assembly 5 includes a rear leg 51 and a rear caster wheel 52; the length of the rear leg 51 is greater than the length of the front leg 41, and after the front leg 41 and the rear leg 51 contact the ground, the first connecting rod 31 forms a 30° angle with the ground (see attached diagram). Figure 11 (As shown). The design of the front leg 41 and the rear leg 51 enables easy mobility of the system. By limiting the length difference between the front and rear legs 51 and cooperating with the first link 31 to form a 30° golden tilt angle, the power generation efficiency of the photovoltaic module is directly improved.

[0063] In one specific implementation, when there are two component mounting platforms 100, the first support tube 21 of the first component mounting platform 100, the second support tube 22 of the second component mounting platform 100, and the third connecting rod 33 are connected by a central bearing; the second support tube 22 of the first component mounting platform 100, the first support tube 21 of the second component mounting platform 100, and the fourth connecting rod 34 are connected by a central bearing. That is, the two folding support units 2 of two adjacent component mounting platforms 100 can be connected by a central bearing, thus eliminating the need for two connecting rods. Specifically, assembling two component mounting platforms 100 requires 6 connecting rods; assembling three component mounting platforms 100 requires 8 connecting rods; and assembling four component mounting platforms 100 requires 10 connecting rods.

[0064] Reference Appendix Figure 11 As shown, the working principle of the foldable movable photovoltaic support system in this embodiment is as follows:

[0065] In its folded state, the entire photovoltaic support system can significantly save space. During use, by pulling outwards along the second connecting rods 32 at both ends, the two support tubes of the folding support unit 2 gradually move closer to each other around the central rivet. End and middle bearings ensure the connecting rods do not deflect. Linear bearings 6 ensure the rear leg 51 remains vertical at all times, while also reducing jamming during system deployment. The component support bar 7 is infinitely adjustable in length via end bearings, and multiple holes on the support bar 7 allow for the sharing of multiple component sizes. The front leg assembly 4 and rear leg assembly 5 are equipped with casters, saving effort during folding and unfolding. The entire photovoltaic support system utilizes the front and rear legs to create a 30° golden angle, greatly increasing the power generation of the photovoltaic modules.
