A three-fold photovoltaic panel support

Abstract

This utility model discloses a three-fold photovoltaic panel bracket, mainly composed of foldable and connectable first, second, and third bracket plates. Its innovation lies in the following: the second bracket plate has a second support section on its back, including a fixing plate, two-section folding plates, and a double-fastening system. A male fastener is located at the end of the third folding plate, which, in the unfolded state, engages with the first female fastener on the third bracket plate to form a stable triangular structure; when folded, the male fastener engages with the second female fastener on the second fixing plate, firmly locking the support components in their storage position. The bracket plate is composed of horizontally foldable units, and with the help of elastic bands and D-ring adjustment mechanisms, it achieves both longitudinal and lateral double folding. This design solves the problems of poor stability and loose storage of traditional brackets, combining the advantages of a stable structure, compact folding, and adjustable angle, making it suitable for the field of portable photovoltaic equipment.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a three-fold photovoltaic panel bracket. Background Technology

[0002] With the increasing demand for mobile energy, portable folding photovoltaic panels are widely used in outdoor activities, emergency preparedness, and other scenarios. Existing portable photovoltaic panels typically use simple support legs or integrated canvas brackets, which mainly suffer from the following drawbacks: Poor structural stability: Traditional support legs are mostly simple "I" or "A" shaped structures that rest directly on the ground. This open-loop support structure is not stable enough and is prone to swaying or even tipping over in windy weather or on uneven ground, affecting power generation efficiency and equipment safety.

[0003] Poor storage and portability: For folding purposes, many brackets are separate from the main photovoltaic panel, requiring them to be carried and installed separately, a cumbersome process that is prone to losing parts. Some integrated brackets, after folding and storage, have loose support legs and other components without effective securing measures, making them prone to shaking, collisions, or snagging with other items during transportation, causing damage or inconvenience.

[0004] Limited functionality and inconvenient adjustment: Many simple brackets have fixed angles and cannot be effectively adjusted according to changes in the solar altitude angle, which affects power generation efficiency.

[0005] Therefore, how to design a photovoltaic panel support that can ensure structural stability when unfolded, compactness and sturdiness when folded, and ease of operation and adjustment is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a three-fold photovoltaic panel bracket, which aims to solve the problems of unstable structure and loose storage of existing portable photovoltaic panel brackets.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a three-fold photovoltaic panel support, comprising: A plurality of first support plates (1), a plurality of second support plates (2) and a plurality of third support plates (3), wherein the first support plates (1) and the second support plates (2) are foldable and connected, and the second support plates (2) and the third support plates (3) are foldable and connected; The second support part includes: a second fixing plate (21) fixed to the back of the second bracket plate (2); The second folding plate (22) has one end that can be folded and connected to the second fixed plate (21); The third folding plate (23) has one end that can be folded and connected to the second folding plate (22); The first female buckle (261) is disposed on the third support plate (3); The second female buckle (262) is disposed on the second fixing plate (21); And a male buckle (27) is provided at one end of the third folding plate (23) away from the second folding plate (22); the male buckle (27) is adapted to engage with the first female buckle (261) in the bracket unfolded state, or to engage with the second female buckle (262) in the bracket folded state; The first support portion includes: a first fixing plate (11) fixed to the back of the first support plate (1); a first folding plate (12) with one end foldably connected to the first fixing plate (11); and a first elastic band (13) with one end fixedly connected to the back of the first support plate (1) and the other end fixedly connected to the end of the first folding plate (12) away from the first fixing plate (11).

[0008] Furthermore, the second support also includes a second elastic band (24), one end of which is fixedly connected to the back of the second bracket plate (2), and the other end is fixedly connected to the end of the second folding plate (22) away from the second fixing plate (21).

[0009] Furthermore, the second support also includes a second connecting elastic band (25) and a connector (30). One end of the second connecting elastic band (25) is fixedly connected to the second folding plate (22), and the other end is connected to the second elastic band (24) through the connector (30).

[0010] Furthermore, the connector (30) is a D-ring buckle.

[0011] Furthermore, the first support plate (1), the second support plate (2), and the third support plate (3) are all composed of at least two plate units that can be folded and connected to each other arranged horizontally.

[0012] Through the above technical solution, this utility model has at least the following beneficial effects: The structure is extremely stable: In the unfolded state, the male buckle of the second support part engages with the first female buckle on the third support plate, so that the second support plate, the support leg (the combination of the second folding plate and the third folding plate) and the third support plate together form a closed triangular mechanical structure, which greatly enhances the overall rigidity and wind resistance of the support, far superior to the traditional open-loop support.

[0013] Compact and sturdy storage: In the folded state, the same male buckle engages with the second female buckle on the second fixing plate, firmly fixing the folded support leg to the back of the second bracket plate. This solves the problem of loose and wobbly parts in the traditional bracket when folded, making the overall structure compact and neat, which greatly facilitates transportation and carrying.

[0014] This product serves two purposes and features a clever design: by using the same male buckle and two female buckles in different positions, it achieves both "unfolding support and locking" and "folding storage and locking" functions with the fewest possible components, resulting in a streamlined and efficient structural design.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Please see Figures 1 to 4 The present invention provides a three-fold photovoltaic panel support, the basic structure of which consists of three parts connected in series: several first support plates (1), several second support plates (2), and several third support plates (3). The first support plates (1) are foldably connected to the second support plates (2) through a flexible connection (such as high-strength fabric), and the second support plates (2) are foldably connected to the third support plates (3) in the same way, which constitutes the longitudinal three-segment folding of the support.

[0026] Furthermore, each row of support panels, namely the first support panel (1), the second support panel (2), and the third support panel (3), is not a single piece of panel, but is composed of at least two panel units that can be folded and connected to each other arranged horizontally. This "horizontal + vertical" grid-like folding design allows large-area photovoltaic panel arrays to be folded into compact blocks the size of only a single panel unit, greatly improving portability.

[0027] Please see Figures 1 to 4 The core innovation of this utility model lies in the second support part set on the back of the second support plate (2).

[0028] Support leg structure: The second support includes a second fixed plate (21) serving as a base, which is firmly fixed to the back of the second support plate (2) near the connection point with the first support plate (1). The support leg itself consists of two parts: a second folding plate (22) and a third folding plate (23). One end of the second folding plate (22) is hinged to the second fixed plate (21) via a hinge or similar structure to achieve folding; one end of the third folding plate (23) is hinged to the other end of the second folding plate (22). This two-section folding leg design can shorten the storage length while maintaining the support height.

[0029] Dual-function locking system: At the free end of the third folding plate (23), there is a male buckle (27).

[0030] A first female buckle (261) is provided at the top edge of the third support plate (3).

[0031] A second female buckle (262) is provided on the surface of the second fixing plate (21).

[0032] Workflow (expanded): such as Figures 1 to 4 As shown, when the support needs to be unfolded, the folded photovoltaic panel array is opened, and the support leg, consisting of the second folding plate (22) and the third folding plate (23), is unfolded. The end of the support leg, i.e., the male buckle (27), is aligned and fastened with the first female buckle (261) on the third support plate (3). After fastening, the second support plate (2), the support leg, and the third support plate (3) form a stable triangle, providing strong support for the entire photovoltaic panel array.

[0033] Workflow (folded): such as Figures 1 to 4 As shown, when storage is required, first unlock the male buckle (27) with the first female buckle (261), and then fold the photovoltaic panel array longitudinally and laterally. At the same time, fold the support legs (the second folding plate (22) and the third folding plate (23)) and flatten them against the back of the second bracket plate (2). At this time, align and fasten the male buckle (27) at the end of the support leg with the second female buckle (262) on the second fixing plate (21) located directly below it. After fastening, the support leg is firmly locked in the storage position, and will not shake or accidentally open, ensuring the overall compactness and transportation safety.

[0034] Assisted Deployment and Angle Adjustment System: To facilitate deployment and provide continuous tension, the second support section is also equipped with a second elastic band (24). One end of it is fixed to the back of the second support plate (2) away from the hinge point, and the other end is connected to the end of the second folding plate (22). When the support leg is deployed, the elastic band is stretched, generating a force to assist deployment and maintain tension.

[0035] To allow for fine-tuning of the support angle, a second connecting spring band (25) and a connector (30) are also provided. Figure 1 As shown, the connector (30) is preferably a D-ring. One end of the second connecting elastic band (25) is connected to the second folding plate (22), and the other end passes through the D-ring (30) and is connected to the second elastic band (24). By pulling or releasing the elastic band on the D-ring (30), the effective length of the entire tensioning system can be changed, thereby precisely adjusting the unfolding angle of the support leg to adapt to the angle of solar radiation at different latitudes and times, maximizing power generation efficiency.

[0036] Auxiliary structure: First support section Please see Figure 1 In order to make the entire support more stable, this embodiment also provides a first support part with a relatively simple structure on the back of the first support plate (1).

[0037] The first support includes a first fixed plate (11), a single-section first folding plate (12), and a first elastic band (13). Its connection is similar to that of the second support: the first fixed plate (11) is fixed to the back of the first support plate (1), the first folding plate (12) is hinged to the first fixed plate (11), and the first elastic band (13) connects the back of the first support plate (1) to the free end of the first folding plate (12), providing tension. This support leg, when deployed, directly supports the ground.

[0038] Similarly, the first support can also be equipped with an adjustment system consisting of a first connecting spring band (14) and a connector (30) (such as a D-ring) for adjusting the support angle of the first support plate (1).

[0039] In summary, this utility model, through its ingenious dual-function locking mechanism combined with a horizontal and vertical double-folding design, successfully achieves ultimate compactness while ensuring structural stability and ease of adjustment, thus possessing high practical value.

[0040] 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. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
