Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic guide rail installation, in particular to a cross-connected guide rail structure. Background Art

[0002] PV system layout strategies are flexible and diverse, ranging from horizontal arrangements to enhance overall aesthetics and uniform illumination, to vertical arrangements to maximize space utilization or address specific lighting conditions. This design philosophy directly impacts the layout of the PV mounting rails, which may require careful horizontal or vertical alignment to match the orientation of the modules. Especially on complex and variable roof structures, a double-layer rail design is sometimes necessary to ensure stable module installation and efficient power generation.

[0003] Existing double-layer rail solutions often face challenges, primarily because the upper and lower rails often utilize different cross-sectional designs, which directly increases the complexity of cross-connections between the rails. These connections often rely on clamping the rails on either side. This not only requires two independent cross-connection components for support, but also significantly increases the variety and number of components required, thereby extending the installation cycle and increasing construction costs. More critically, the multi-component, multi-layer cross-connection often carries a higher risk of failure. If a connection fails, it can adversely affect the stability and power generation efficiency of the entire PV system. Utility Model Content

[0044] A cross-connected guide rail structure includes a connecting guide rail 200, a connected guide rail 300, and a cross assembly 1 for cross-connecting the connecting guide rail 200 and the connected guide rail 300;

[0045] The connecting guide rail 200 and the connected guide rail 300 have the same structure. The cross-section of the connecting guide rail 200 is concave. Two first guide rail clamping portions 2003 are provided at the upper notch of the connecting guide rail 200. The first guide rail clamping portions 2003 are arranged facing each other and are not connected. The upper notch of the connecting guide rail 200 and the two first guide rail clamping portions 2003 form a clamping groove.

[0046] The cross assembly 1 includes a first cross connector 11, a second cross connector 12, a cross adjustment member 13 and a cross fastener 14;

[0047] The first cross-connector 11 includes a cross-abutting portion 111 and a cross-placing portion 112. A placement space is formed between the cross-placing portion 111 and an end of the cross-placing portion 112 away from the cross-abutting portion 111. A first cross-positioning portion 113 is protruded from the bottom of the cross-placing portion. A cross-adjusting strip hole 115 is opened between the cross-abutting portion 111 and the cross-placing portion 112.

[0048] The first cross-connector 11 is clamped to the connecting rail 200 via the first cross-positioning portion 113 and the clamping groove. The lower end of the second cross-connector 12 is penetrated by the cross-adjustment strip hole 115, and one end of the second cross-connector 12 is clamped to the clamping groove.

[0049] The cross adjustment member 13 is installed at the upper end of the second cross connection member 12, and one end of the cross adjustment member 13 close to the cross abutment portion 111 abuts against the cross abutment portion 111. The connected guide rail 300 is placed in the placement space, and the connecting guide rail 200 and the connected guide rail 300 are placed vertically.

[0050] The second cross-connector 12 includes a cross vertical abutment surface 131. The second cross-connector 12 and the cross adjustment member 13 can move along the extension direction of the cross adjustment strip hole 115. The movement is used to adjust the size of the placement space so that the cross vertical abutment surface 131 of the cross adjustment member 13 abuts against the connected guide rail 300.

[0051] The cross adjustment member 13 and the second cross connection member 12 are fixedly installed by the cross fastener 14 .

[0052] like Figure 1-5 As shown, the working principle of the installation structure for cross-connection of guide rails is mainly based on four core steps: snap-in, positioning, adjustment and tightening:

[0053] First, align and snap the first cross-positioning portion 113 of the first cross-connector 11 into the snap-in groove of the connecting guide rail 200. This snap-in groove is formed by the notch at the upper end and two opposing but unconnected first guide rail snap-in portions 2003, ensuring a secure connection between the first cross-connector 11 and the corresponding guide rail 200. Subsequently, pass the lower end of the second cross-connector 12 through the cross-adjustment bar hole 115 of the first cross-connector 11, and snap the end through it into the snap-in groove of the same connecting guide rail 200, further enhancing the stability and reliability of the cross assembly. Then, install the cross-adjustment member 13 on the upper end of the second cross-connector 12, with the end of the cross-adjustment member 13 proximal to the cross-adjustment portion 111 abutting against the cross-adjustment portion 111.

[0054] Next, the connected guide rail 300 is placed vertically on the cross-placement portion 112 of the first cross-connector 11. At this point, the placement space formed by the cross-placement portion 112 and the cross-abutment portion 111 is ample, and the connected guide rail 300 can move freely in the placement space. Adjustment is then performed by moving the second cross-connector 12 and the cross-adjustment member 13 along the extension direction of the cross-adjustment bar hole 115, so that the cross-vertical abutment surface 131 on the cross-adjustment member 13 is tightly abutted against the vertically placed connected guide rail 300. At this point, the cross-adjustment member 13 and the second cross-connector 12 are in the optimal abutment position, and the connected guide rail 300 cannot move. It should be noted that during the adjustment process, one end of the cross-adjustment member 13 always abuts against the cross-abutment portion 111. This adjustment step applies pressure to the connected guide rail 300 through the cross-adjustment member 13 to ensure its stability and prevent shaking.

[0055] Finally, the cross-adjusting member 13 and the second cross-connecting member 12 are fixedly installed at the optimal abutment position using the cross-fastener 14, thereby completing the cross-connection installation process of the guide rail structure.

[0056] It should be noted that the placement order of the second cross-connector 12 , the cross-adjusting member 13 , the cross-fastening member 14 and the connected guide rail 300 can be adjusted according to actual needs, and the above embodiment only provides the optimal placement and installation steps.

[0057] In summary, the present invention first utilizes a snap-fit ​​structure to securely install the first cross-connector 11 and the second cross-connector 12 on one guide rail. Then, the second cross-connector 12 and the cross-adjustment member 13 positioned thereon move on the first cross-connector 11, thereby clamping the second guide rail clamping portion 2004 of the other guide rail 200 and the second cross-positioning portion 114 of the first cross-connector 11. This completes the cross-connection of the two guide rails 200 and facilitates adjustment. The cross-fastener 14 then secures the second cross-connector 12 and the cross-adjustment member 13 in their current positions, further stabilizing the connection between the two guide rails 200 and improving practicality.

[0058] Therefore, the utility model has the following beneficial effects:

[0059] 1. Simplify the installation process: The snap-on and adjustable design makes the installation process more intuitive and simple, reducing the requirements for the professional skills of the installers.

[0060] 2. Improved connection stability: The multiple clamping structures and the pressing effect of the cross adjustment member 13 ensure the stability and reliability of the connection between the guide rails 200, reducing the risk of failure caused by loose connections.

[0061] 3. Enhanced adaptability: The design of the cross-adjustment strip holes 115 allows fine-tuning during installation to adapt to guide rails 200 of different sizes or installation conditions, thereby improving the versatility and flexibility of the installation structure.

[0062] 4. Easy maintenance: When the guide rail 200 needs to be repaired or replaced, the entire cross assembly can be easily disassembled by simply loosening the cross fastener 14, thereby reducing maintenance costs and time.

[0063] 5. Improve overall performance: Stable connection and precise positioning ensure the stability and accuracy of the guide rail structure during operation, improving the overall performance and efficiency of the photovoltaic system.

[0064] To further illustrate, a second cross positioning portion 114 is protruded from the top of one end of the cross placement portion 112 away from the cross abutment portion 111 ;

[0065] The lower ends of the left and right side walls of the connecting guide rail 200 and the connected guide rail 300 are both extended outward to form a second guide rail clamping portion 2004;

[0066] The second guide rail clamping portion 2004 disposed on the connected guide rail 300 close to the second cross positioning portion 114 is clamped with the second cross positioning portion 114 .

[0067] like Figure 2-3 As shown, when the connected guide rail 300 is placed vertically on the cross-placement portion 112 of the first cross-connector 11, the second guide rail clamping portion 2004 at the lower end of the right side wall of the connected guide rail 300 is clamped with the second cross-positioning portion 114 on the first cross-connector 11, realizing the preliminary positioning and connection of the connecting guide rail 200 and the connected guide rail 300 in the vertical direction, so that the connecting guide rail 200 and the connected guide rail 300 can be stabilized during the subsequent adjustment of the cross-adjustment member 13.

[0068] To further explain, the cross abutment portion 111 includes a cross inclined abutment plate 1111 , and the cross inclined abutment plate 1111 has an inclined abutment surface, and the inclined abutment surface is used for abutment of one end of the cross adjustment member 13 .

[0069] like Figure 2-3As shown, in a preferred embodiment, the cross-abutment portion 111 of the first cross-connector 11 includes a cross-inclined abutment plate 1111. This design further enhances the convenience of adjusting the cross-adjustment member 13. Specifically, when the cross-adjustment member 13 is installed at the upper end of the second cross-connector 12, one end of the cross-adjustment member 13 will abut against the cross-inclined abutment plate 1111 of the first cross-connector. The design of the cross-inclined abutment plate 1111 allows the cross-adjustment member 13 to gradually move along the inclination of the cross-inclined abutment plate 1111, thereby gradually adjusting the pressure distribution on the connected guide rail 300 during the movement, making the adjustment force more uniform and reducing stress concentration.

[0070] To further explain, the cross-abutment portion 111 also includes a cross-inclined support plate 1112 and a cross-horizontal support plate 1113, the upper end of the cross-inclined support plate 1112 is fixedly connected to the cross-inclined abutment plate 1111, and the lower end of the cross-inclined support plate 1112 is fixedly connected to one end of the cross-horizontal support plate 1113.

[0071] like Figure 2-3 As shown, after further refinement of the design of the first cross connector 11, the cross abutment portion 111 of the first cross connector 11 is designed as a stable triangular support structure, which is composed of a cross-slanted support plate 1112, a cross-slanted abutment plate 1111, and a cross-horizontal support plate 1113. This design not only enhances the stability of the cross abutment portion, but also optimizes the interaction with the cross adjustment member 13. The specific working principle is as follows:

[0072] The cross-slanted support plate 1112 serves as one side of the triangular support structure, with its upper end fixedly connected to the cross-slanted abutment plate 1111, and its lower end fixedly connected to one end of the cross-horizontal support plate 1113. This design forms a stable triangular structure that can provide stable support in all directions.

[0073] When the cross adjustment member 13 is mounted on the upper end of the second cross connector 12 and moves along the cross adjustment strip hole 115 until it contacts the cross abutment portion 111, one end of the cross adjustment member first abuts against the cross inclined abutment plate 1111. The design of the cross inclined abutment plate 1111 allows the cross adjustment member to gradually adapt to and fit the cross abutment portion during the tightening process, achieving a smoother transition.

[0074] As the cross adjustment member 13 is further tightened, the cross inclined abutment plate 1111 transfers the pressure to the cross inclined support plate 1112, which is then dispersed to the cross horizontal support plate 1113. The stability of the triangular support structure ensures that the pressure can be evenly distributed over the entire cross abutment portion, reducing stress concentration and local wear.

[0075] By precisely moving the second cross-connector 12 and the cross-adjustment member 13 along the extension direction of the cross-adjustment strip holes 115, the linked guide rails 300 can be precisely adjusted and tightened. Once the desired tightness is achieved, the cross-adjustment member 13 and the second cross-connector 12 are fixed together using the cross-fastener 14, ensuring the stability and long-term reliability of the entire cross-connected guide rail structure.

[0076] To further illustrate, the second cross-connector 12 includes a cross-connection fixing portion 121;

[0077] Cross-connection clamping portions 122 are respectively extended from both sides of the lower end of the cross-connection fixing portion 121 , and the cross-connection clamping portions 122 are clamped with the clamping grooves.

[0078] like Figure 2-3 As shown, after further refinement of the design of the second cross-connector 12, the second cross-connector 12 includes a cross-connection fixing portion 121 and cross-connection clamping portions 122 extending from both sides of the lower end of the fixing portion. This design enables the second cross-connector to more firmly engage with the clamping groove of the guide rail, thereby enhancing the stability and reliability of the entire cross-connector assembly. The specific working principle is as follows:

[0079] The cross-connection fixing portion 121, as the main body of the second cross-connector 12, is responsible for bearing and transmitting the compressive force from the cross-adjusting member 13. It also provides a stable support base for the cross-connection clamping portion 122. The cross-connection clamping portions 122 extend from either side of the lower end of the cross-connection fixing portion 121. Their shape and size match the guide rail's retaining grooves. During installation, the cross-connection clamping portions 122 are inserted into and retain in the retaining grooves, forming a stable mechanical connection.

[0080] To further explain, the cross-connection clamping portion 122 includes a cross-connection clamping hook 123 . The cross-connection clamping hook 123 is disposed to protrude outward along the extending direction of the cross-connection clamping portion 122 .

[0081] like Figure 2-3 As shown, after a detailed description of the cross-connection latch design of the second cross-connector 12, its operating principle can be further understood. The cross-connection latch 122 includes cross-connection hooks 123, which protrude outward along the extension direction of the cross-connection latch 122. This design enables the cross-connection latch 122 to more effectively engage with the engaging groove of the connecting guide rail 200, enhancing the stability and reliability of the connection.

[0082] First, the cross-connect hooks 123 are key components of the cross-connect latch 122. They protrude outward, creating a "reverse" effect. As the cross-connect latch 122 is inserted into the engaging groove, the cross-connect hooks 123 gradually expand and contact the sidewalls of the engaging groove, ultimately fully engaging. These cross-connect hooks 123 fit tightly against the sidewalls of the engaging groove, creating a mechanical lock.

[0083] More importantly, due to the protruding design of the cross-connection hooks 123, they can provide additional resistance when subjected to external forces, preventing the cross-connection clips 122 from accidentally falling out of the engaging grooves. This design significantly improves the stability and reliability of the connection.

[0084] To further explain, a cross resistance increasing pattern 124 is provided inside the cross connection clamp portion 122 .

[0085] like Figure 2-3 As shown, the cross-resistance increasing lines 124 are a series of uneven textures or grooves engraved or pressed inside the cross-connection clamping portion 122. These cross-resistance increasing lines 124 can generate additional friction when in contact with the cross fastener 14, preventing the cross fastener 14 from sliding or disengaging when subjected to external forces, thereby further enhancing the stability and reliability of the connection.

[0086] To further illustrate, the cross adjustment member 13 is an L-shaped member;

[0087] One end of the L-shaped member is provided with a cross-tilt adjustment surface 132, and the cross-tilt adjustment surface 132 cooperates and abuts with the cross-tilt abutment plate 1111 of the cross abutment portion 111, and the other end of the L-shaped member abuts against the upper end of the second guide rail clamping portion 2004 of the connected guide rail 300.

[0088] like Figure 2-3 As shown, in a preferred embodiment, the cross adjustment member 13 is designed as an L-shaped member. This shape not only makes the installation process more intuitive and simple, reduces the requirements for the professional skills of the installer, but also enables it to provide support and adjustment functions in both horizontal and vertical directions.

[0089] One end of the known L-shaped member is provided with a cross-tilt adjustment surface 132 for mating with the cross-tilt abutment plate 1111 of the cross-abutment portion 111; the other end directly abuts the upper end of the second guide rail clamping portion 2004 of the connected guide rail 300. During the adjustment process, the cross-tilt adjustment surface 132 fits tightly against the cross-tilt abutment plate 1111, and the relative position between the two is adjusted by moving the cross-adjustment member 13. Because both surfaces are inclined, the pressure distribution on the vertical guide rail can be gradually changed during movement, achieving a smoother and more uniform adjustment effect. The other end of the L-shaped member directly abuts the upper end of the second guide rail clamping portion 2004 of the connected guide rail 300, and the pressing force of the cross-adjustment member 13 ensures a stable connection between the connected guide rail 300 and the first cross-connecting member 11. This design allows the cross-adjustment member 13 to not only adjust the degree of compression, but also directly participate in the stability of the guide rail structure.

[0090] To further illustrate, the horizontal surface of the L-shaped member is provided with a first cross-connecting through hole 133 , and the vertical surface of the L-shaped member is the cross-vertical abutting surface 131 , which abuts against the connected guide rail 300 ;

[0091] The cross-connection fixing portion 121 is provided with a second cross-connection through hole 1210;

[0092] The cross fastener 14 passes through the first cross connection through hole 133 and the second cross connection through hole 1210 in sequence, so as to fix the cross adjustment member 13 and the second cross connection member 12 in place.

[0093] As is well known, the L-shaped cross-adjustment member 13 has a horizontal surface and a vertical surface. A first cross-connection through-hole 133 is defined on the horizontal surface for engaging with the cross fastener 14. The cross-connection fixing portion 121 is the main portion of the second cross-connection member 12 and defines a second cross-connection through-hole 1210 corresponding to the first cross-connection through-hole 133 on the L-shaped cross-adjustment member for receiving the cross fastener 14 for secure installation.

[0094] like Figure 2-3As shown, the cross fastener 14 can be a cross fastener such as a bolt or a screw, and its length and diameter need to be selected according to actual needs to ensure a stable connection. During installation, the cross fastener 14 passes through the first cross-connection through-hole 133 on the L-shaped cross-adjusting member and the second cross-connection through-hole 1210 on the second cross-connecting member 12 in sequence. Then, by rotating the head of the cross fastener 14, such as a nut or a cap, it is tightened, so that the L-shaped cross-adjusting member 13 and the second cross-connecting member 12 are tightly fixed together. When the cross fastener 14 is tightened, the vertical surface of the L-shaped cross-adjusting member 13 acts as a cross vertical abutment surface 131, which will firmly abut the connected guide rail 300, providing direct support and pressing force. Not only does it ensure the stability and reliability of the connected guide rail 300, but the tightening force of the cross fastener 14 also prevents the cross-adjusting member 13 from loosening or displacement.
