A composite material photovoltaic panel frame

Abstract

This utility model belongs to the field of photovoltaic panel frame technology, and in particular to a composite material photovoltaic panel frame, including frame profiles and connectors. The ends of the frame profiles are fixedly connected by connectors. The middle part of the connecting angle bracket of the connector is bent at 90 degrees. Both ends of the connecting angle bracket are fixedly connected to elastic arc plates. An anti-detachment arc plate is placed on the side of the elastic arc plate that abuts against the frame profile. In this utility model, elastic arc plates and support members are set on the connecting angle brackets used to connect the frame profiles. After the connecting angle brackets are inserted into the ends of the frame profiles, the support members provide stable and effective support for the elastic arc plates, so that the elastic arc plates are tightly abutted against the frame profiles, achieving a stable connection between the two. At the same time, the resistance generated between the anti-detachment arc plate and the frame profile is used to prevent the connecting angle brackets from loosening and falling off. The greater the external force, the greater the resistance generated, further improving the stability of the connection and achieving a stable splicing combination between the frame profiles.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel frame technology, specifically a composite material photovoltaic panel frame. Background Technology

[0002] Photovoltaic frame profiles manufactured using composite material pultrusion processes have relatively weak lateral strength, and the strength at the drilling location decreases significantly after the profile is perforated. Existing frame connection methods typically involve interference fit between corner brackets and the profile cavity, or mechanical connection with bosses on the corner brackets with perforations. Interference fits are highly random; slight differences in the dimensions of the corner brackets or the frame cavity can lead to the frame detaching under stress after connection, resulting in poor connection stability and inconvenience in use.

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in one embodiment of this utility model, a composite material photovoltaic panel frame includes a frame profile 1 and a connector 2. The ends of the frame profile 1 are fixedly connected by the connector 2, so that the ends of the frame profile 1 can be stably spliced ​​together using the connector 2 to complete the splicing combination between the frame profiles 1. The middle part of the connecting angle bracket 201 of the connector 2 is bent at ninety degrees. Both ends of the connecting angle bracket 201 are fixedly connected to elastic arc plates 2011, and the side of the elastic arc plate 2011 that abuts against the frame profile 1 is provided with an anti-detachment arc plate 20. 3. The anti-detachment arc plate 203 is rotatably connected to the elastic arc plate 2011 via a pin, and a support member 202 is placed between two adjacent elastic arc plates 2011 at the same end of the connecting angle bracket 201. This facilitates the stable connection of the ends of the frame profile 1 together using the connecting angle bracket 201. At the same time, the elastic arc plate 2011 is used to improve the stability of the connection between the connecting angle bracket 201 and the frame profile 1. The anti-detachment arc plate 203 is used to assist in fixing the connecting angle bracket 201, preventing the connecting angle bracket 201 from loosening and falling off the frame profile 1, and ensuring a stable connection.

[0025] like Figure 1 As shown, in some embodiments, the end portion of the frame profile 1 is provided with an inclined splicing surface, and the frame profile 1 is provided with an insertion hole for inserting into the connecting bracket 201, so as to use the connecting bracket 201 to stably connect the ends of the two spliced ​​frame profiles 1 together.

[0026] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the elastic arc plates 2011 at both ends of the connecting corner bracket 201 are bent toward the side away from the support member 202. The arc shape of the elastic arc plate 2011 makes it easy to smoothly insert the connecting corner bracket 201 into the frame profile 1, realizing a smooth connection between the two and improving the ease of use. In addition, the side of the elastic arc plate 2011 that contacts the frame profile 1 is provided with a mounting groove 2013. One end of the mounting groove 2013 is connected to the shaft groove 2014 opened at the end of the elastic arc plate 2011, which makes it easy to smoothly install the anti-detachment arc plate 203 onto the elastic arc plate 2011.

[0027] The elastic arc plate 2011 has an insert groove 2012, which is matched with the insert strip 2023 on the support member 202. The support member 202 is stably installed between the elastic arc plates 2011 through the cooperation between the two, so as to provide stable and effective support for the elastic arc plate 2011. The elastic arc plate 2011 is tightly pressed against the frame profile 1, and the insert strip 2023 is fixedly connected to the contact plate 2021. An elastic deformation waist 2022 is provided between two adjacent contact plates 2021, so that when the elastic arc plate 2011 is compressed and deformed, the support member 202 can deform along with it to ensure stable use.

[0028] Among them, one end of the anti-arc plate 203 is integrally provided with a bearing seat 2031. The bearing seat 2031 is rotatably connected to the shaft groove 2014 by a pin. A torsion spring is installed between the bearing seat 2031 and the shaft groove 2014. The torsion spring is coaxially arranged with the pin, which facilitates the use of the pin and the bearing seat 2031 to stably install the anti-arc plate 203 onto the elastic arc plate 2011, so that the two can be stably used together. At the same time, the torsion spring can apply an effective driving force to the anti-arc plate 203. After the connecting bracket 201 is inserted into the end of the frame profile 1, the anti-arc plate 203 can abut against the frame profile 1.

[0029] Among them, the anti-arc plate 203 extends from the shaft groove 2014 into the mounting groove 2013. The side of the anti-arc plate 203 that contacts the frame profile 1 is provided with uniformly distributed anti-arc racks 2032. The anti-arc racks 2032 increase the frictional resistance between the anti-arc plate 203 and the frame profile 1, effectively preventing the connecting corner 201 from loosening and falling off from the end of the frame profile 1, thus achieving a stable connection between the two.

[0030] When splicing and assembling the frame profile 1, one side of the connecting corner bracket 201 is inserted into one end of one frame profile 1, and the other side is inserted into one end of another frame profile 1. This will stably connect the ends of the two frame profiles 1 together, thus smoothly completing the splicing and assembly between the frame profiles 1.

[0031] During the process of connecting the corner bracket 201 to the end of the frame profile 1, the frame profile 1 will come into contact with the elastic arc plate 2011, so that the elastic arc plate 2011 will transfer the stress generated by the contact to the support member 202. The elastic deformation waist 2022 of the support member 202 will deform appropriately. At the same time, the support member 202 will apply a reverse force to the elastic arc plate 2011, so that it will come into close contact with the frame profile 1, thus completing the stable connection between the two.

[0032] Meanwhile, during the insertion process, the anti-detachment arc plate 203 on the elastic arc plate 2011 will be resisted by the frame profile 1 and housed in the mounting groove 2013. Under the action of the torsion spring on the pin, it will resist the frame profile 1. When the connecting angle bracket 201 slides loosely from the frame profile 1, the anti-detachment rack 2032 on the anti-detachment arc plate 203 will abut against the frame profile 1, blocking the loosening and falling off of the connecting angle bracket 201. Therefore, the greater the pulling force that pulls the connecting angle bracket 201 off, the greater the resistance generated between the anti-detachment arc plate 203 and the frame profile 1, effectively preventing the connecting angle bracket 201 from loosening and falling off from the frame profile 1, and stably connecting the ends of the frame profile 1 together.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
