Description

Technical Field

[0001] This invention relates to the field of photovoltaic bracket technology, specifically to a quick-installation snap-on structure, installation method, and photovoltaic system. Background Technology

[0002] In the field of photovoltaic (PV) mounting systems, it is often necessary to fix various panels and components (such as PV modules 300) to supporting purlins. Traditional fixing methods commonly use bolt connections. While this method is reliable, it has revealed a series of problems in practical applications:

[0003] First, the installation process is inconvenient. (See attached document for reference.) Figure 1 and 2 As shown, it is usually necessary to tighten the bolts 400 on both sides of the photovoltaic module 300 at the same time. However, when the space on one side of the purlin 200 is narrow or blocked by other structures, it is difficult for the construction personnel to operate, resulting in installation difficulties or even failure to install.

[0004] Secondly, the installation is inefficient and costly. Each connection point requires at least one set (usually two sets) of 400 bolts, nuts, and washers. This not only results in high material costs but also in the time and labor required to tighten the 400 bolts, significantly increasing labor costs. For large projects with thousands of connection points (such as photovoltaic power plants), the cumulative cost and time consumption are enormous. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick-installation snap-on structure, installation method and photovoltaic system, which can be installed quickly without complicated tools, has low requirements for installation space, ensures sufficient strength and reliability of connection, and effectively reduces overall cost.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation snap-fit ​​structure, comprising a purlin and a snap-fit. The purlin has a U-shaped groove on its side plate, the U-shaped groove including a horizontal groove and vertical grooves at both ends, forming a spring piece in the area enclosed by the U-shaped groove. The snap-fit ​​includes a main wall, with an upper groove on the upper right side and a bend below the main wall. A notch is provided on the left side of the bend, and a protrusion is provided at the connection between the bend and the main wall. The snap-fit ​​is inserted into the horizontal groove through the bend, the notch slides at a right angle within the horizontal groove and rotates around the right side of the horizontal groove to a vertical position. At this point, the protrusion lifts the spring piece, and the snap-fit ​​is pressed downwards, causing the top of the purlin to embed into the upper groove. The spring piece rebounds and forms an inverted snap-fit ​​limiting structure with the protrusion, and the left side of the bend fits against the right side of the purlin.

[0007] Furthermore, the notch is any one of a right-angle notch, a V-shaped notch, or an arc-shaped notch.

[0008] Furthermore, the right side of the upper groove is a first inclined surface, used to guide the top of the purlin to be inserted.

[0009] Furthermore, the top surface of the protrusion is a second inclined surface, used to guide the spring sheet to slide in and finally be held against the inclined surface of the protrusion.

[0010] Furthermore, the upper groove includes an upper groove surface, a first inclined surface, and an upper opening, the size of which is larger than that of the upper groove surface; the left side of the bend is aligned with the rightmost end of the upper groove surface in the vertical direction.

[0011] Furthermore, after installation, the buckle has its groove fitting against the top of the purlin, its raised top surface abutting against the bottom of the spring clip, and its bend fitting against the right side of the left side plate of the purlin, forming a stable fixing structure.

[0012] Furthermore, a mounting platform is provided extending from the upper right of the main wall, and the upper groove is formed on the bottom surface of the mounting platform; an installation platform for installing photovoltaic modules is provided extending from the upper left of the main wall.

[0013] Furthermore, the purlin has a U-shaped cross-section, comprising a left side plate, a bottom plate, and a right side plate connected in sequence, with the spring clip located on the left side plate.

[0014] On the other hand, an installation method for the aforementioned quick-installation snap-fit ​​structure includes the following steps:

[0015] Step 1: Align the curved part of the buckle with the horizontal groove of the purlin and push it in;

[0016] Step 2: Make the notch edge of the bend contact the right angle of the right side of the horizontal groove, and rotate the buckle around the right angle until it is vertical;

[0017] Step 3: In the vertical position, the protrusion lifts the spring piece, and at the same time, the notch disengages from the right angle of the right side of the horizontal groove, allowing the buckle to move vertically along the right side of the horizontal groove.

[0018] Step 4: Press the buckle down so that the top of the purlin enters the upper groove. The spring will spring back and form an inverted locking mechanism with the protrusion, completing the installation.

[0019] On the other hand, a photovoltaic system includes photovoltaic modules and a quick-installation clip structure as described in any one of claims 1-8; the clip is used to securely connect the photovoltaic modules and the purlins.

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention features a quick-installation snap-fit ​​structure that replaces traditional bolt fastening with a continuous "rotate-lift-press-lock" action, achieving tool-free rapid installation and significantly saving installation time and labor costs. By eliminating standard parts such as bolts and nuts, material costs are reduced. Its unique inverted locking mechanism and multi-faceted fit structure ensure connection strength and reliability, with excellent wind and vibration resistance. This ingenious design requires minimal installation space, making it particularly suitable for challenging installation environments such as high-altitude or confined spaces.

[0022] 2. The quick-installation buckle structure installation method of this invention concretizes and standardizes the efficient installation operation process; through three main steps of "push-rotate-press down", reliable installation can be completed without any tools. The process is simple and easy to learn, which can greatly reduce the technical requirements for installers, improve the consistency of on-site construction efficiency, and eliminate quality hazards caused by missing bolts or insufficient torque.

[0023] 3. The photovoltaic system of the present invention includes photovoltaic modules and a quick-installation snap-fit ​​structure; the snap-fit ​​is used to fix and connect the photovoltaic modules and purlins. Applying this snap-fit ​​structure to the photovoltaic system clarifies its important application scenario and provides an extremely efficient and economical connection solution for the installation of photovoltaic modules. It can significantly shorten the construction cycle of the photovoltaic system, reduce the cost of the support system, and at the same time, the reliable connection ensures the safety and stability of the long-term operation of the photovoltaic system.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see the appendix Figure 3-11 The present invention provides a quick-installation snap-fit ​​structure, including a purlin 200 and a snap-fit ​​100, the core purpose of which is to achieve a quick and reliable connection between the two without the need for bolts.

[0040] Reference Appendix Figure 4 As shown, a U-shaped groove is provided on the side plate of the purlin 200. The U-shaped groove includes a horizontal groove 204 and vertical grooves 205 located at both ends of the horizontal groove 204. A spring piece 206 is formed in the area enclosed by the U-shaped groove. The advantage of this design is that the spring piece 206 can be integrally formed with the U-shaped groove, which has a simple structure and is elastic and reliable.

[0041] Reference Appendix Figure 5-7 As shown, the buckle 100 includes a main wall 1, and the upper right side of the main wall 1 (with...) Figure 7(From a viewing angle) An upper groove 2 is provided, the function of which is to finally lock the top of the purlin 200. A bend 3 is provided below the main wall 1, which bends to one side. A notch 4 is provided on the left side 31 of the bend 3, and a protrusion 5 is provided at the connection between the bend 3 and the main wall 1. During installation, the buckle 100 is aligned with the bend 3 and pushed into the insertion groove 204. At this time, the notch 4 slides on the right angle in the groove 204, and then rotates around the right side 2041 of the groove 204 (with the contact point as the fulcrum) to a vertical state. At this time, the protrusion 5 just lifts the spring piece 206, causing it to elastically deform. At the same time, due to the rotation into place, the contour of the notch 4 makes it disengage from the right angle 2042 of the right side 2041 of the groove 204, releasing the horizontal constraint. At this time, the buckle 100 can move freely in the vertical direction. Finally, the buckle 100 is pressed downwards, causing the top of the purlin 200 to embed into the upper groove 2. The spring piece 206 quickly rebounds, and the bottom of the spring piece 206 is engaged with the top surface of the protrusion 5 (the second inclined surface 51), forming an inverted locking structure with the protrusion 5 to prevent the buckle 100 from coming off upwards. The left side 31 of the bend 3 is tightly fitted with the right side 2041 of the purlin 200. In this way, the upper groove limiting, the side surface contact, and the inverted locking of the spring piece 206 together form a very stable three-point fixing structure.

[0042] The quick-installation buckle structure of this invention completely abandons the traditional bolt connection method. Through ingenious rotation and pressing action and reverse locking, the buckle 100 can be installed quickly and reliably. This not only solves the fundamental problem of insufficient operating space, but also greatly reduces the number of parts and installation steps, thereby significantly reducing material costs and installation time.

[0043] In this invention, the notch 4 is any one of a right-angle notch 4, a V-shaped notch 4, or an arc-shaped notch 4. Right-angle notches 4, V-shaped notches 4, or arc-shaped notches 4 are easy to process, providing a smoother rotational contact surface between the notch 4 and the right angle 2042 of the transverse groove 204, reducing jamming, and making the rotation of the buckle 100 within the transverse groove 204 smoother and more controllable, thus improving the smoothness and fault tolerance of the installation process.

[0044] In this invention, reference is made to the appendix. Figure 7 As shown, the right side of the upper groove 2 is a first inclined surface 22, which is used to guide the top of the purlin 200 into insertion. By setting the right side of the upper groove 2 as the first inclined surface 22, a guide opening is formed. In the final stage of the snap-fit ​​100 pressing down, the first inclined surface 22 can effectively guide the top of the purlin 200 to slide accurately and easily into the upper groove 2, preventing installation difficulties or structural damage caused by alignment deviations, and improving the success rate of installation on the first attempt.

[0045] In this invention, reference is made to the appendix. Figure 7As shown, the top surface of the protrusion 5 is a second inclined surface 51, which guides the bottom of the spring piece 206 to slide in and finally rest against the second inclined surface 51 of the protrusion 5. The second inclined surface 51 of the protrusion 5 has two functions: first, when the buckle 100 rotates and lifts the spring piece 206, it plays a smooth guiding role, avoiding hard impact that could cause plastic deformation or damage to the spring piece 206; second, in the final locked state, the bottom of the spring piece 206 is stably held against the second inclined surface 51, making the force distribution of the inverted structure more reasonable and the connection more stable.

[0046] In this invention, the upper groove 2 includes an upper groove surface 21, a first inclined surface 22, and an upper opening 23, the size of which is larger than that of the upper groove surface 21. The left side surface 31 of the bend 3 is vertically aligned with the rightmost end of the upper groove surface 21, such that the distance from the rightmost end of the upper groove surface 21 to the main wall 1 is equal to the distance from the left side surface 31 of the bend 3 to the main wall 1. This distance is preferably equal to the thickness of the spring piece 206. This ensures that when the buckle 100 is installed in place, its bend 3 can achieve maximum area contact with the right side surface 2041 of the purlin 200, and the upper groove 2 can also firmly hold the top of the purlin 200. This surface contact at the upper and lower points together constitutes a stable structural foundation that resists torsion and pull-out torque, as well as a maximum limiting effect on the purlin 200.

[0047] In this invention, after installation, the buckle 100 has its groove 2 fitting against the top of the purlin 200, its top surface of the protrusion 5 abutting against the bottom of the spring piece 206, and its left side 31 of the bend 3 fitting against the right side 2041 of the left side plate 201 of the purlin 200, forming a stable fixing structure. These three points of action together form a three-dimensional stable constraint, ensuring that the buckle 100 will not loosen, rotate, or fall off under force, resulting in high connection reliability.

[0048] In this invention, a mounting platform 6 extends from the upper right of the main wall 1, and the upper groove 2 is formed on the bottom surface of the mounting platform 6; a mounting platform 7 for installing the photovoltaic module 300 extends from the upper left of the main wall 1. The mounting platform 6 extending from the upper right facilitates the creation of the upper groove 2 and enhances the strength of this part; the mounting platform 7 in the upper left provides a dedicated platform for directly connecting the photovoltaic module 300 or other external components, making the buckle 100 a modular component integrating connection and installation functions, simplifying the structure of the entire support system.

[0049] In this invention, reference is made to the appendix. Figure 4As shown, the purlin 200 has a U-shaped cross-section and includes a left side plate 201, a bottom plate 202, and a right side plate 203 connected in sequence. The spring clip 206 is disposed on the left side plate 201. The purlin 200 adopts a common U-shaped cross-section purlin 200, and the spring clip 206 is integrated into its side plate, so that this innovative snap-fit ​​structure can be directly adapted to widely used standard profiles, greatly improving the versatility and market application potential of the solution, without the need for complex modifications to the existing purlin 200 body.

[0050] The quick-installation snap-fit ​​structure provided by this invention replaces traditional bolt fastening through a continuous "rotation-lifting-pressing-locking" action. This achieves tool-free rapid installation, significantly saving installation time and labor costs. By eliminating standard parts such as bolts and nuts, material costs are reduced. Its unique inverted locking mechanism and multi-faceted fitting structure ensure connection strength and reliability, with good wind and vibration resistance. This ingenious design requires minimal installation space, making it particularly suitable for scenarios where construction is inconvenient, such as high-altitude or confined spaces.

[0051] Reference Appendix Figure 8-11 As shown, the present invention also provides an installation method based on the aforementioned quick-installation snap-on structure, comprising the following steps:

[0052] Step 1: As shown in a1 and a2, align the bend 3 of the buckle 100 with the transverse groove 204 of the purlin 200 and push it in;

[0053] Step 2: As shown in a3, make the edge of the notch 4 of the bend 3 contact the right angle 2042 of the right side face 2041 of the transverse groove 204, as shown in a4 and a5, and rotate the buckle 100 around the right angle 2042 to the vertical position.

[0054] Step 3: As shown in a5, in the vertical state, the protrusion 5 lifts the spring piece 206, and at the same time, the notch 4 disengages from the right side 2041 of the horizontal groove 204 at a right angle 2042, and the buckle 100 can move vertically along the right side 2041 of the horizontal groove 204.

[0055] Step 4: As shown in a6, press the buckle 100 downwards so that the top of the purlin 200 enters the upper groove 2, the spring piece 206 rebounds and forms an inverted locking position with the protrusion 5, and the installation is completed.

[0056] The quick-installation buckle structure installation method of the present invention concretizes and standardizes the efficient installation operation process; through three main steps of "push-rotate-press down", reliable installation can be completed without any tools. The process is simple and easy to learn, which can greatly reduce the technical requirements for installers, improve the consistency of on-site construction efficiency, and eliminate quality hazards caused by missing bolts or insufficient torque.

[0057] This invention also provides a photovoltaic system, including a photovoltaic module 300 and the quick-installation clip structure; the clip 100 is used to fix the photovoltaic module 300 and the purlin 200. Applying this clip 100 structure to a photovoltaic system clarifies its important application scenarios, providing an extremely efficient and economical connection solution for the installation of photovoltaic modules. This can significantly shorten the construction cycle of the photovoltaic system, reduce the cost of the support system, and at the same time, the reliable connection ensures the safety and stability of the photovoltaic system's long-term operation.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
