Description

Technical Field

[0001] The utility model belongs to the technical field of solar cells, and specifically relates to a solar cell component frame structure. Background Art

[0002] Solar cell modules are mainly composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. They have the characteristics of long service life and strong mechanical resistance to external compressive force. Among them, the aluminum alloy frame mainly plays the role of encapsulation and protection for the solar cells. When installing conventional solar panels, auxiliary steel structure brackets are required to connect and fix the aluminum alloy frame of the solar cell module to the steel structure bracket. The main shortcomings are as follows: (1) The solar cell module is installed and fixed with a steel structure, which is cumbersome and expensive to install. (2) After the solar cell module is installed and fixed, it is not convenient to move and disassemble, which affects the flexible use of the roof space by residents and is not suitable for application scenarios of flat roofs in rural areas.

[0020] Example

[0021] like Figures 1 to 4 As shown, this embodiment provides a solar cell assembly frame structure, which includes a frame body, and the frame body is used to install a solar cell panel. This embodiment is provided with a box body and a box cover based on the frame body, wherein the box cover is used to cover the box body, and the frame body and the box body are movably connected. Specifically, the frame body can be unfolded and stored relative to the box body. When the solar cell panel is in use, the frame body is unfolded relative to the box body, and when it is not in use, the frame body is stored relative to the box body and then covered with the box cover. Preferably, the overall weight of the equipment is between 15 and 25 kilograms, and an adult can carry it relatively easily.

[0022] The structural form adopted by the utility model is convenient for users to unfold and store solar panels, and is suitable for small-area application scenarios such as rural roofs. It is convenient for users to move and disassemble (store) the equipment when not in use. For example, when there is insufficient sunlight in winter, the solar panels can be stored, or when other things need to be dried on the roof, the solar panels can be stored to free up roof space.

[0023] In this embodiment, a fixing ring is provided on the outer wall of the box body. The fixing ring and the box body are an integral structure and are mainly used to connect a fixing rope. In special circumstances where the wind force on the roof is strong, the box body can be fixed with the fixing rope. For example, one end of the fixing rope is tied on the fixing ring, and the other end is fixed to other knottable or fixed places on the roof (for example, fixed to the roof ground with nails).

[0024] The connection structure between the frame body and the box body in this embodiment is as follows: sliding guide rods are symmetrically arranged at the left and right ends of the box body, and a slider that can slide relative to it and a limit nut for limiting the slider are sleeved on the sliding guide rods. Connecting rods rotatably connected to the slider are symmetrically arranged on the left and right sides of the lower end of the frame body. A support rod is arranged between the back of the frame body and the rear end of the box body, one end of the support rod is rotatably connected to the bottom of the rear end of the box body, and the other end is connected to the back of the frame body through a self-locking hinge, wherein the self-locking hinge adopts a 90° self-locking hinge or other self-locking hinges with adjustable angles, and technical personnel in this field can select an appropriate self-locking angle according to actual needs; through the above-mentioned arrangement, the frame body realizes the state conversion of expansion and storage with the cooperation of structures such as the connecting rod and the slider. In order to facilitate the expansion and storage of the frame body, a handle is also arranged at the upper end of the frame body in this embodiment, and it is more convenient for users to operate the frame body to expand or store through the handle.

[0025] The connecting rod and the frame body are an integrated structure. The frame body and the solar panel can be assembled by equipment. The connecting rod and the slider are detachably connected. After the frame body and the solar panel are assembled, the connecting rod and the slider are rotatably connected. The sliding guide rod adopts a screw structure, which is provided with an external thread matching the limit nut. The limit nut is used to limit the sliding block after the slider moves into position. Preferably, there are two limit nuts on a sliding guide rod, which are respectively located at the front and rear ends of the slider.

[0026] In a further preferred embodiment, in order to improve the supporting strength of the frame body when it is unfolded, the present embodiment also includes an auxiliary support rod with one end being active and the other end being rotatably connected to the rear end of the box body. Preferably, there are two auxiliary support rods and they are symmetrically arranged with the support rod as a reference. When supporting, the support rod is first fixed and then the auxiliary support rod is supported. In a preferred embodiment, the supporting points of the auxiliary support rod and the support rod are distributed in a triangle.

[0027] Through the above arrangement, in the non-use state, the frame body and other connected parts are stored in the box body. When the frame body needs to be unfolded, the frame body is lifted up by holding the handle, the slider moves backward along the sliding guide rod, and the support rod is rotated upward relative to the box body to unfold the support rod and the frame body. When the two are unfolded to 90° or the set angle, the self-locking hinge is locked. If the inclination angle of the frame body is not appropriate, the slider can be moved to adjust the inclination angle of the frame body. After the adjustment is completed, the two limit nuts at both ends of the slider are moved toward the slider and against the slider to limit the slider. The frame body is unfolded by the above operation, and the frame body is stored in the box body by the reverse operation.

[0028] The above is the preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the design principle and technical solution of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
