Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic frame technology, and in particular relates to a simplified and portable photovoltaic frame. Background Technology

[0002] Currently, most mainstream photovoltaic (PV) frames use aluminum alloy profiles, connected by corner brackets on the four sides to form a rectangular frame. Their design primarily focuses on securing them to the support system and their resistance to long-term outdoor weathering. However, with the diversification of PV applications, such as outdoor surveying, emergency power supply, temporary facilities, and personal portable power generation, traditional PV frames have revealed many limitations: Firstly, its fixed structure cannot provide stable support for temporary placement, requiring an additional support system, which increases cost and carrying burden. Secondly, in order to meet structural strength requirements, the profiles are usually designed to be relatively thick and heavy, which is not conducive to lightweighting and portability.

[0003] Existing technologies have seen some photovoltaic frame designs that integrate foldable support leg structures, giving photovoltaic panels a certain degree of self-support capability. However, these designs still have some common drawbacks: First, its support leg structure is often quite complex, using multi-links, independent hinges or large integral parts, resulting in increased weight, higher cost and bulky size after storage. Secondly, the outriggers have a single function, and they can usually only be folded in a limited number of fixed positions. They cannot flexibly adjust the support points and height according to different terrain or lighting angles, thus limiting their range of use. Finally, these designs typically employ a support method where legs are deployed at the four corners or sides of the frame to protect the edges, resulting in all edges being lifted off the ground. This not only increases the complexity and material usage of the structure but also makes the overall center of gravity too high, leading to insufficient stability. Summary of the Invention

[0004] The purpose of this invention is to provide a simplified and portable photovoltaic frame. Through the design of the support leg structure, it can be folded for storage and unfolded for support. At the same time, a new short-side profile is designed and a soft sleeve is set on the outer surface, which can directly touch the ground. It adopts an asymmetrical design with a single-sided triangular support and the opposite side directly touching the ground. Only the support leg mechanism needs to be deployed on one side of the long side, while the other side uses the reinforced short profile frame to directly contact the ground. Stable support is achieved with the fewest parts and the simplest movement method, which is a breakthrough in structural simplification.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a simplified and portable photovoltaic frame, including a leg mechanism, two long side profiles, two short side profiles, and two locking leg mechanisms; The long side profile includes a back plate portion, the front top edge of the back plate portion is provided with a component pressing edge, the front middle portion of the back plate portion is provided with a component pad edge, the lower inner side of the component pad edge is provided with an inner vertical edge parallel to the back plate portion, a rectangular cavity with a bottom opening is formed between the inner vertical edge, the component pad edge and the back plate portion, and a plurality of mounting holes are linearly provided on the inner vertical edge and the back plate portion. The short-side profile includes a vertical plate portion, the outer side of which is provided with an arc-shaped edge, and a cavity with a crescent-shaped cross-section is formed between the arc-shaped edge and the vertical plate portion. The outer surface of the short-side profile is covered with a soft sleeve. The two short-side profiles and the two long-side profiles form a rectangular frame, and the inner sides of the ends of the short-side profiles and the long-side profiles are connected by angle iron. The support leg mechanism is located at one end between two long side profiles. The support leg mechanism includes a set of legs. A connecting pipe is fixed through the top end between the two legs. Both ends of the connecting pipe are provided with internal threads. The connecting pipe is located at one end between the two long side profiles. The end of the connecting pipe is fixed to the long side profile through internal threads, fastening screws and mounting holes on the long side profile. An annular opening is provided on the outer side of the middle part of the leg body. The leg-locking mechanism includes an elastic thin plate. One end of the elastic thin plate is fixed with a bolt. The other end of the elastic thin plate is fixed and rotatably connected to the long side profile through the bolt and the mounting port. The elastic thin plate is located directly below the rectangular cavity and its thickness is less than the width of the rectangular cavity. One side of the other end of the elastic thin plate is provided with an outward protrusion. The inner side of the outward protrusion is fixed with a protrusion that mates with the annular opening.

[0006] Furthermore, when the elastic thin plate is arranged parallel to the rectangular cavity of the long side profile, the protrusion is located below the long side profile.

[0007] Furthermore, when the leg mechanism has an acute angle with the long side profile, the elastic plate is located on the outside of the leg body, and the distance between the elastic plate and the leg body is less than the length of the protrusion.

[0008] Furthermore, the inner and outer sides of the elastic sheet near the long side profile are both fixed with rubber pads, and the elastic sheet is interference-fitted with the rectangular cavity through the rubber pads.

[0009] Furthermore, the bottom of the leg body is provided with a rubber sleeve, and a lower crossbeam is fixed at the bottom between the two legs.

[0010] Furthermore, both ends of the short side profile are provided with caps, and the inner side of the caps is provided with an insertion end that is interference-fitted with the cavity of the short side profile.

[0011] This utility model has the following beneficial effects: 1. This utility model, through the design of the support leg structure, can be folded and stored and unfolded for support. At the same time, it features a novel short-side profile with a soft sleeve on the outer surface, allowing it to directly contact the ground. It adopts an asymmetrical design with a single-sided triangular support and the opposite side directly contacting the ground. Only the support leg mechanism needs to be deployed on one side of the long side, while the other side uses its reinforced short profile frame to directly contact the ground. Stable support is achieved with the fewest parts and the simplest movement method, representing a breakthrough in structural simplification.

[0012] 2. This utility model, through the design of a novel short-side profile, has a double-layer plate structure with certain strength, which not only allows it to directly touch the ground, but also has the advantage of being lightweight. In addition, the design of the long-side profile without C-side further reduces the weight, achieving a lightweight overall frame and avoiding the problem of excessive weight and poor portability after adding a support leg mechanism.

[0013] 3. This utility model uses a locking leg mechanism to lock the angle of the support leg mechanism, thereby improving stability. The locking leg mechanism can be folded into the long side profile, making the locking leg mechanism, which is mainly composed of elastic thin plate, lightweight, small footprint, low cost and easy to operate.

[0014] 4. This utility model features a design with a large number of evenly spaced mounting openings on the long side profile, and the support leg mechanism and the retractable leg mechanism are connected by bolts and screws, making it easy to install and disassemble. Users can operate it quickly and adjust the position of the two parts at will, so that the frame has the ability to adjust to different angles and the ability to change the support. It can be arranged according to the user's common angles, thus improving the applicability.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
