[0030] Embodiment 1

[0031] Embodiment 1 of the present application provides a frame assembly, the frame assembly comprising:

[0032] A first unit frame 100;

[0033] The second unit frame 200 is arranged to intersect with the first unit frame 100 and is spliced ​​with the first unit frame 100;

[0034] A connecting corner block 400 is disposed at the joint of the first unit frame 100 and the second unit frame 200, and the inner surfaces of the two intersecting limiting planes of the connecting corner block 400 correspond to the outer surfaces of the first unit frame 100 and the second unit frame 200 one by one;

[0035] The two fixing blocks 300 are arranged one by one corresponding to the two intersecting limiting planes of the connecting corner block 400, and the inner surfaces of the two intersecting limiting planes of the connecting corner block 400 are in close contact with the corresponding outer surfaces of the first unit frame 100 and the second unit frame 200 through the fixing blocks 300.

[0036] like Figure 1As shown, in this embodiment, it is exemplarily explained that the first unit frame 100 and the second unit frame 200 can be made of aluminum profiles, and the shapes of the cross sections of the first unit frame 100 and the second unit frame 200 can be set to be the same. The first unit frame 100 and the second unit frame 200 can be arranged horizontally and vertically respectively, that is, the first unit frame 100 can be perpendicular to the second unit frame 200. The first unit frame 100 and the second unit frame 200 can be parallel and spaced to two. When two first unit frames 100 and two second unit frames 200 are spliced, they can be specifically spliced ​​into a rectangular frame assembly. The photovoltaic assembly can be arranged on the inner side of the aforementioned frame assembly, and the frame assembly can be coated on the outer edge of the aluminum outer frame of the photovoltaic assembly.

[0037] Of course, in some embodiments, the first unit frame 100 and the second unit frame 200 can also be spliced ​​into frame components of other shapes. For example, in some special cases, when one of the four photovoltaic components in the original 2*2 rectangular array is cancelled according to actual needs, the frame component can be set to a stepped shape accordingly.

[0038] like Figure 1 and Figure 2 As shown, the connecting corner block 400 can be arranged at the joint of the first unit frame 100 and the second unit frame 200. The material of the connecting corner block 400 can be aluminum, which can be arranged in an "L" shape, and the connecting corner block 400 can be arranged in a right angle shape. In this case, the connecting corner block 400 has two mutually perpendicular limiting planes, that is, two sides of the "L" shape. The two mutually perpendicular limiting planes of the connecting corner block 400 can correspond to the outer surfaces of the first unit frame 100 and the second unit frame 200 one by one.

[0039] The connecting corner block 400 can be connected to the corresponding outer surfaces of the first unit frame 100 and the second unit frame 200 by the inner surfaces of the two mutually perpendicular limiting planes of the two fixing blocks 300 to achieve close contact, thereby fixing and limiting the spliced ​​first unit frame 100 and the second unit frame 200. The two fixing blocks 300 are arranged in a one-to-one correspondence with the first unit frame 100 and the second unit frame 200, and can be arranged on the outer surface or the upper and lower sides of the first unit frame 100 or the second unit frame 200. The fixing block 300 can also be made of aluminum, and the connection method between the first unit frame 100 and the second unit frame 200 can be welding. Of course, in some embodiments, the fixing block 300 can also adopt other connection methods, such as bonding, sleeve connection, etc.

[0040] The connecting corner block 400 can be connected to the two fixed blocks 300, and the two can be connected in a detachable manner, for example, by connecting or snapping together with bolts or other components; of course, the two can also be connected in a fixed manner, such as by welding or bonding.

[0041] It is understandable that the present application uses two fixing blocks 300 to closely contact the inner surfaces of the two intersecting limiting planes of the connecting corner block 400 with the corresponding outer surfaces of the first unit frame 100 and the second unit frame 200, so that the first unit frame 100 and the second unit frame 200 can be spliced ​​into a frame assembly with a stable structure. Compared with the method of connecting the unit frames through angle codes, the structure of the present application is relatively simple and does not require high processing accuracy, and the preparation process is more convenient; and compared with the method of connecting through angle steel, the present application does not involve drilling the unit frame, which ensures the structural strength of the unit frame and the sealing effect in the cavity.

[0042] Specifically, the fixing block 300 includes a first fixing portion 310 and a second fixing portion 320, the first fixing portion 310 is connected to the lower surface of the first unit frame 100 or the second unit frame 200, the second fixing portion 320 is connected to the first fixing portion 310, and the connecting corner block 400 is arranged between the inner surface of the second fixing portion 320 and the outer surface of the first unit frame 100 or the second unit frame 200, and the connecting corner block 400 is connected to the second fixing portion 320.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, for example, the first fixing portion 310 and the second fixing portion 320 can both be set as rectangular blocks, and the first fixing portion 310 and the second fixing portion 320 can be perpendicular to each other and spliced ​​into an "L"-shaped structure; the first fixing portion 310 and the second fixing portion 320 can be integrally formed. The first fixing portion 310 can be used to be welded and fixed on the outer surface of the first unit frame 100 or the second unit frame 200, and the end of the first fixing portion 310 connected to the first unit frame 100 or the second unit frame 200 is the end of the first fixing portion 310 away from the second fixing portion 320, so that when the first fixing portion 310 is connected to the first unit frame 100 or the second unit frame 200, the second fixing portion 320 can be spaced apart from the outer surfaces of the first unit frame 100 and the second unit frame 200 to form a space for arranging the end of the connecting corner block 400, that is, a groove structure with an opening is formed between the fixing block 300 and the outer surface of the first unit frame 100 or the second unit frame 200, and the end of the connecting corner block 400 is arranged in the groove structure. After the connecting corner block 400 is arranged in place, the connecting corner block 400 can also be connected to the second fixing portion 320 so that the connecting corner block 400 can be fixed and limited by the two fixing blocks 300 at the joint of the first unit frame 100 and the second unit frame 200.

[0044] It is understandable that, in this embodiment, by reasonably setting the shape of the fixing block 300 , it is convenient to fix and limit the connecting corner block 400 through two fixing blocks 300 , so as to improve the stability when the first unit frame 100 and the second unit frame 200 are spliced.

[0045] Specifically, the frame assembly further includes a fastening bolt 500 , which is threadedly connected to the fixing block 300 , and the fastening bolt 500 passes through the fixing block 300 and is connected to the connecting corner block 400 .

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the fastening bolt 500 may include a bolt shank 510 and a bolt head 520, and the bolt head 520 may be coaxially arranged and fixedly connected with the bolt shank 510. The bolt shank 510 may be threadedly connected with the second fixing portion 320, and the second fixing portion 320 may be provided with a threaded hole 530 matching with the bolt shank 510, and the bolt shank 510 may pass through the second fixing portion 320 and be connected with the connecting angle block 400. The bolt shank 510 and the connecting angle block 400 may be in abutment relationship, that is, the bolt shank 510 presses and fixes the connecting angle block 400 on the first unit frame 100 or the second unit frame 200. The bolt shank 510 and the connecting angle block 400 may also be in a threaded connection relationship, that is, the connecting angle block 400 is also provided with a threaded hole 530 matching with the bolt shank 510. The bolt head 520 may be set in a knob shape to facilitate the tightening bolt 500 to be screwed.

[0047] It is understandable that in this embodiment, the connection corner block 400 and the fixing block 300 are connected by fastening bolts 500, which can further improve the stability of the connection between the connection corner block 400 and the fixing block 300, so that the first unit frame 100 and the second unit frame 200 can be effectively spliced.

[0048] Specifically, the inner surfaces of the first unit frame 100 and the second unit frame 200 are both provided with mounting grooves 600 for installing photovoltaic modules. The two sides of the photovoltaic modules are respectively abutted against the two side walls of the mounting grooves 600 . Sealing pads 700 are provided on the two side walls of the mounting grooves 600 .

[0049] like Figure 4 and Figure 5As shown, in this embodiment, the mounting groove 600 can be set to a "U" shape, and its opening can face the inner surface of the frame assembly, so as to facilitate the arrangement of the photovoltaic assembly in the mounting groove 600. When the photovoltaic assembly is arranged in the frame assembly, the upper and lower sides of the photovoltaic assembly are respectively abutted against the two side walls of the mounting groove 600, that is, the two side walls of the mounting groove 600 clamp the upper and lower sides of the photovoltaic assembly respectively. The two side walls of the mounting groove 600 are provided with a sealing pad 700 for abutting against the upper and lower sides of the photovoltaic assembly, and the sealing pad 700 can be made of rubber, silicone and other materials. When the photovoltaic assembly is arranged in the mounting groove 600, the upper and lower sides of the photovoltaic assembly squeeze the sealing pad 700 to deform it.

[0050] It is understandable that in this embodiment, by providing a mounting groove 600 for arranging the photovoltaic module on the first unit frame 100 and the second unit frame 200 and providing a sealing gasket 700 in the mounting groove 600, the sealing effect between the photovoltaic module and the frame module can be improved.

[0051] More specifically, a limiting protrusion 610 is provided on one of the side wall of the installation groove 600 and the sealing gasket 700, and a fixing groove 710 is provided on the other one. The sealing gasket 700 is provided on the side wall of the installation groove 600 by means of the limiting protrusion 610 and the fixing groove 710 which cooperate with each other.

[0052] like Figure 4 and Figure 5 As shown, in this embodiment, it is exemplarily explained that the limiting protrusion 610 and the fixing groove 710 can be understood as a mortise and tenon structure that cooperates with each other, and the cross-sectional shapes of the limiting protrusion 610 and the fixing groove 710 can be set to be rectangular, dovetail, arc, etc. In this embodiment, the limiting protrusion 610 is set on the side wall of the installation groove 600 and the fixing groove 710 is set on the sealing rubber pad 700 as an example. Along the width direction of the side wall of the installation groove 600, the limiting protrusion 610 can also be arranged at intervals, such as two, three, etc.; and the fixing groove 710 and the limiting protrusion 610 are arranged one by one to cooperate with each other.

[0053] It can be understood that this embodiment arranges the sealing gasket 700 on the installation groove 600 by means of the limiting protrusions 610 and the fixing grooves 710 that cooperate with each other, which can not only ensure that the sealing gasket 700 is installed firmly while avoiding drilling on the side wall of the installation groove 600, but also realize the rapid positioning of the sealing gasket 700 on the side wall of the installation groove 600, so that the installation process of the sealing gasket 700 is more convenient, time-saving and labor-saving.

[0054] Specifically, a sealing structure is provided at the joint between the first unit frame 100 and the second unit frame 200 .

[0055] like Figure 1 As shown, in this embodiment, the two ends of the first unit frame 100 and the second unit frame 200 can be set at a sharp angle of 45 degrees, and when the first unit frame 100 and the second unit frame 200 are spliced, the two end faces at the splicing point can better abut. After splicing, a sealing structure can also be set at the splicing point of the first unit frame 100 and the second unit frame 200, that is, a sealing structure is set at the right angle of the frame assembly.

[0056] It is understandable that in this embodiment, the joint between the first unit frame 100 and the second unit frame 200 is sealed by a sealing structure, so that the inner hole structures such as the cavities of the first unit frame 100 and the second unit frame 200 can be prevented from being infiltrated with water and damp.

[0057] More specifically, half-groove structures 810 are provided on both the upper and lower sides of the joint of the first unit frame 100 and the second unit frame 200. The two half-groove structures 810 located on the same side of the first unit frame 100 and the second unit frame 200 enclose a glue groove structure 800, and the sealing structure is a sealant filled in the glue groove structure 800.

[0058] like Figure 2 and Figure 6 As shown, in this embodiment, it is exemplarily explained that the material of the half-groove structure 810 can also be set to aluminum, and the half-groove structure 810 can be welded on the upper and lower sides of the first unit frame 100 or the second unit frame 200. Looking from the direction of looking down at the frame assembly, the half-groove structure 810 can be set to a "U" shape, and both sides of the "U" shape can be set parallel to the extension direction of the first unit frame 100, and the bottom of the "U" shape can be parallel to the end face of the first unit frame 100 set at a 45-degree angle. The opening of the half-groove structure 810 can be oriented in a direction away from the first unit frame 100 and the second unit frame 200, so that when the first unit frame 100 and the second unit frame 200 are spliced, the two half-groove structures 810 on the same side of the first unit frame 100 and the second unit frame 200 are opposite, and can be enclosed to form a closed glue groove structure 800. It is not difficult to see that the glue groove structure 800 is symmetrically arranged with respect to the abutting surface when the first unit frame 100 and the second unit frame 200 are spliced. The sealing structure can be set as a sealant. After the first unit frame 100 and the second unit frame 200 are spliced, the sealant groove structure 800 is glued to form the sealing structure.

[0059] It can be understood that in this embodiment, a half-groove structure 810 is set on the first unit frame 100 and the second unit frame 200 to form a glue groove structure 800 for gluing when the first unit frame 100 and the second unit frame 200 are spliced, so as to facilitate the preparation of the sealing structure at the splicing point of the first unit frame 100 and the second unit frame 200, and can ensure the sealing effect of the sealing structure on the splicing point.

[0060] Specifically, the first unit frame 100 and the second unit frame 200 both include a bottom frame 910 and a top frame 920 . The top frame 920 is disposed on the top of the bottom frame 910 . The bottom frame 910 and the top frame 920 are detachably connected.

[0061] like Figure 1 and Figure 6 As shown, in this embodiment, the first unit frame 100 and the second unit frame 200 are each composed of two unit bodies, namely a bottom frame 910 and a top frame 920. The top frame 920 is detachably arranged on the top of the bottom frame 910, one side wall of the mounting groove 600 is arranged on the top frame 920, and the other side wall is arranged on the bottom frame 910.

[0062] It can be understood that in this embodiment, the first unit frame 100 and the second unit frame 200 are both configured to be detachably connected to the bottom frame 910 and the top frame 920. When the first unit frame 100 or the second unit frame 200 is partially deformed or damaged, only the bottom frame 910 or the top frame 920 needs to be replaced to reduce maintenance costs.

[0063] More specifically, a mounting slot 930 is provided at the top of the bottom frame 910 , and the top frame 920 is movably inserted into the mounting slot 930 .

[0064] like Figure 6 As shown, in this embodiment, the mounting slot 930 can be set to a dovetail shape, and the top frame 920 can be provided with a portion that matches the mounting slot 930, and its shape is the same as the mounting slot 930. The top frame 920 can move in and out of the mounting slot 930 along the extension direction of the bottom frame 910 to achieve a detachable connection with the bottom frame 910. Of course, in some embodiments, the mounting slot 930 can also be other shapes, such as a "T" shape, an inverted "L" shape, etc.

[0065] It is understandable that this embodiment provides a mounting slot 930 on the bottom frame 910 for the top frame 920 to move into, thereby facilitating a detachable connection between the bottom frame 910 and the top frame 920 and improving convenience during assembly and disassembly.

[0066] The implementation principle of a frame assembly provided in the first embodiment of the present application is:

[0067] When in use, the top frame 920 is moved into the installation slot 930 of the bottom frame 910 to prepare the first unit frame 100 and the second unit frame 200 respectively, and then the sealing rubber pad 700 is respectively clamped on the two side walls of the installation slot 600 by the matching limiting protrusions 610 and the fixing grooves 710, and then the photovoltaic components are arranged in the installation slot 600 of the first unit frame 100 and the second unit frame 200, and then the first unit frame 100 and the second unit frame 200 are spliced, so that the two half-slot structures 810 on the same side of the first unit frame 100 and the second unit frame 200 are enclosed to form a glue groove structure 800, and then the glue groove structure 800 is glued to form a sealing structure at the splicing of the first unit frame 100 and the second unit frame 200. The fixing block 300 is then welded to the outer surface of the first unit frame 100 and the second unit frame 200, and then the connecting angle block 400 is connected to the two fixing blocks 300 at the joint of the first unit frame 100 and the second unit frame 200. During the connection, the fastening bolt 500 is threadedly connected to the fixing block 300 and passes through the fixing block 300 to connect to the connecting angle block 400.

[0068] The present application uses two fixing blocks 300 to closely contact the inner surfaces of the two intersecting limiting planes of the connecting corner block 400 with the corresponding outer surfaces of the first unit frame 100 and the second unit frame 200, so that the first unit frame 100 and the second unit frame 200 can be spliced ​​into a frame assembly with a stable structure. Compared with the method of connecting the unit frames through angle codes, the structure of the present application is relatively simple and does not require high processing accuracy, and the preparation process is more convenient; and compared with the method of connecting through angle steel, the present application does not involve drilling the unit frame, which ensures the structural strength of the unit frame and the sealing effect in the cavity.
