Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a bracket for supporting photovoltaic panels, specifically a foldable, portable and structurally stable double-fold photovoltaic panel bracket. Background Technology

[0002] With the increasing popularity of portable energy storage power supplies and outdoor activities, portable photovoltaic (PV) panels are being used more and more widely. To achieve optimal solar energy reception efficiency, PV panels typically need to be supported at a certain tilt angle. Existing portable PV panel supports mostly use simple A-frame brackets or telescopic support poles.

[0003] However, these existing support solutions have some shortcomings: some supports are relatively complex in order to pursue stability, containing multiple independent rods and connectors, which makes the unfolding and storage process cumbersome and time-consuming, and easy to lose parts; other supports are too simplified in order to pursue portability, resulting in insufficient stability after unfolding, especially in windy outdoor environments, where they are prone to swaying or even tipping over, affecting power generation efficiency and equipment safety.

[0004] Therefore, how to design a portable photovoltaic panel bracket that can be quickly and easily unfolded and folded, while ensuring structural stability after unfolding and having a small storage volume, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a double-folding photovoltaic panel bracket, which aims to solve the problems of complicated unfolding and folding operations, poor structural stability, and inconvenient storage of existing portable photovoltaic panel brackets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-folding photovoltaic panel support, comprising: a first-layer support (1), wherein the first-layer support (1) is composed of a plurality of first support plates (11) foldably connected; a second-layer support (2), wherein the second-layer support (2) is composed of a plurality of second support plates (21) foldably connected, wherein the first support plates (11) and the second support plates (21) are foldably connected; at least one first support part (10) is disposed on the back of the first support plate (11); and at least one second support part (20) is disposed on the back of the first support plate (11). The back of the second support plate (21) is described; the first support part (10) is provided with a foldable first support component (12), and the free end of the first support component (12) is provided with an insert plate part (13); the second support part (20) is provided with a foldable second support component (22), and the second support component (22) is provided with a fixing hole (23) adapted to the insert plate part (13), which is used to lock the first support component (12) and the second support component (22) by inserting the insert plate part (13) into the fixing hole (23) after the first support component (12) and the second support component (22) are folded.

[0007] In a preferred embodiment of the present invention, the first support portion (10) includes a fixing plate (14) and a support plate (12a) serving as the first support assembly (12). The fixing plate (14) is fixed to the back of the first support plate (11) and has a groove (15) formed thereon. One end of the support plate (12a) is folded and connected to the edge of the groove (15), so that the support plate (12a) can be stored in the groove (15) when not in use, keeping the back flat. The other end of the support plate (12a) is provided with the insert plate portion (13).

[0008] In a preferred embodiment of the present invention, the second support part (20) includes a support plate (22a) as the second support component (22). One end of the support plate (22a) is foldably connected to the top of the back of the second support plate (21) by means of a hinge or the like.

[0009] In a preferred embodiment of this utility model, the second support part (20) further includes a first elastic band (24). One end of the first elastic band (24) is fixed to the bottom of the back of the second support plate (21), and the other end is fixed to the end of the support plate (22a) away from its folding connection end. Preferably, the position where the first elastic band (24) is fixed at the bottom of the back of the second support plate (21) is aligned vertically with the folding connection position of the support plate (22a) on the second support plate (21). This design allows the first elastic band (24) to be stretched when the support plate (22a) is folded upward, thereby generating a continuous tension force and making the entire support structure more robust.

[0010] In a preferred embodiment of this invention, the second support portion (20) further includes a second elastic band (25). One end of the second elastic band (25) is fixed to one end of the support plate (22a) near the second support plate (21), and the other end is provided with a D-ring (26) or other type of fastener. This design provides additional fastening force after insertion and locking, further enhancing stability.

[0011] As a preferred embodiment of the present invention, when the bracket is unfolded, the first support component (12) and the second support component (22) cooperate with the insert plate (13) and the fixing hole (23) to form a stable triangular limiting structure together with the plane of the first support plate (11) and the second support plate (21), and use the stability principle of triangle to ensure the rigid support of the bracket.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Simple to unfold and quick to fold: The entire unfolding process only requires folding two support components, inserting once, and snapping once. The operation is intuitive and requires no additional tools, greatly saving deployment time. Folding is equally convenient in reverse.

[0014] 2. Stable and reliable structure: The rigid connection between the insert plate and the fixing hole forms a stable triangular support structure, which effectively ensures the rigidity of the support. At the same time, the pre-tightening force of the first elastic band and the secondary fastening of the second elastic band provide elastic buffer and additional stability for the support, and it has strong wind resistance.

[0015] 3. Excellent integrated storage and easy to carry: All support components are integrated on the back of the support plate, so there are no independent loose parts after folding, making them less likely to be lost. The double-folding design makes the overall thickness and volume thin and small after storage, making it very easy to carry and store. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figures 1 to 6This utility model provides a double-folding photovoltaic panel support, which includes a first-layer support (1) and a second-layer support (2). The first-layer support (1) is composed of multiple first support plates (11) connected by flexible connections (such as fabric, flexible plastic, etc.), and can be folded along the connection points. Similarly, the second-layer support (2) is also composed of multiple second support plates (21) that can be folded and connected. The first-layer support (1) and the second-layer support (2) are also connected by flexible connections, so that the entire support can be folded like a book, and finally folded into a compact shape (such as...). Figure 2 (As shown). The photovoltaic cells can be attached to the front of the first support plate (11) and the second support plate (21).

[0028] A first support portion (10) is provided on the back of at least one first support plate (11). Figure 3 As shown, the first support part (10) includes a fixing plate (14), which is fixed to the back of the first support plate (11) by means of bonding or riveting. A groove (15) is formed on the fixing plate (14). A support plate (12a) serving as a first support assembly (12) is accommodated in the groove (15). One end of the support plate (12a) is hinged to the edge of the groove (15) and can be turned outward around the hinge point. At its free end, i.e., the other end, a flat insert portion (13) is protruding.

[0029] Corresponding to the first support part (10), a second support part (20) is provided on the back of the second support plate (21). Figure 4 As shown, the second support (20) includes a support plate (22a) that serves as a second support assembly (22). One end of the support plate (22a) is foldably connected to the top of the back of the second support plate (21). A retaining hole (23) is provided on the plate body of the support plate (22a), the shape and size of which match the insert plate (13).

[0030] To provide preload and enhance stability, the second support (20) is also equipped with two elastic bands. One end of the first elastic band (24) is fixed to the bottom back of the second support plate (21), and its fixing point is substantially aligned vertically with the folding connection point of the support plate (22a). The other end of the first elastic band (24) is fixed to the free end of the support plate (22a) (i.e., the end away from the folding connection point). One end of the second elastic band (25) is fixed to the end of the support plate (22a) near the folding connection point, and the other end is fitted with a D-ring (26).

[0031] The working principle and usage process of this utility model are as follows:

[0032] Expand: First, as follows Figure 2The bracket in the folded state shown is fully unfolded, so that all the first support plates (11) and the second support plates (21) form a large plane.

[0033] Folding support assembly: The support plate (12a) in the first support part (10) is folded downward from the groove (15) so that it forms a certain angle with the plane of the first support plate (11). At the same time, the support plate (22a) in the second support part (20) is folded upward. During the folding process, the first elastic band (24) is gradually stretched, generating tension.

[0034] Insertion Locking: When the support plate (22a) is folded to a predetermined angle, the insertion plate portion (13) at the end of the support plate (12a) is aligned and inserted into the retaining hole (23) on the support plate (22a). After insertion, the support plate (12a), the support plate (22a), and the partial planes of the first and second support plates (11, 21) to which they are connected together form a stable triangular limiting structure (e.g., Figure 6 As shown in the figure, the main rigid support is achieved.

[0035] Secondary reinforcement: Finally, fasten the D-ring (26) at the end of the second elastic band (25) into the appropriate position of the first elastic band (24), and use the elastic force of the second elastic band (25) to tighten the formed triangular structure a second time to prevent it from coming off when subjected to unexpected force, and further improve the stability of the overall structure.

[0036] The folding and storage process is the reverse of the above steps: unfasten the D-ring (26), pull the insert plate (13) out of the fixing hole (23), then fold the support plate (12a) and the support plate (22a) back to their original positions, and finally fold the entire bracket along the flexible connection.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
