Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a quick assembly connector for photovoltaic module frames. Background Technology

[0002] Photovoltaic panels are solar panels. Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Most solar panels are primarily made of silicon, but their widespread use is limited due to their high manufacturing cost. Compared to ordinary batteries and rechargeable batteries, solar cells are more energy-efficient and environmentally friendly green products. There are two methods of solar power generation: one is the light-to-heat-to-electricity conversion method, and the other is the direct light-to-electricity conversion method.

[0003] A search of existing published patents (CN202121371924.4) reveals a patent titled "A Quick-Assembled Aluminum Frame Profile for Solar Photovoltaic Panels." This patent includes a first aluminum frame body and a second aluminum frame body, which are connected and fixed via a quick-connect assembly. The quick-connect assembly comprises a connecting positioning plate, a locking groove, a connecting positioning slot, a fixing body, a movable block, a protrusion, a return spring, a locking block, a connecting spring, a locking screw, and a knob. The connecting positioning plate is integrally formed and symmetrically arranged at both ends of the first aluminum frame body. This solar photovoltaic panel aluminum frame profile, designed with the quick-connect assembly, allows for rapid connection and fixation, exhibiting excellent stability, high assembly precision, and simple operation. It provides convenience for workers while ensuring assembly quality and improving the economic efficiency of assembly work.

[0004] However, the aforementioned frame profiles are not very effective at fixing photovoltaic panels, making it difficult to connect the photovoltaic panels to the frame profiles. Utility Model Content
