Example 1

Referring to fig. 1 to 7, the X direction represents the width direction, the Y direction represents the height direction, and the Z direction represents the length direction.

The present embodiment provides an assembly frame unit 100, which includes a first structure a and a second structure B; the first structure a and the second structure B are arranged along the height direction Y or the width direction X of the component frame unit 100. In addition, a third structure is arranged in an area adjacent to the first structure and/or the second structure, and the frame units of the plurality of components are firmly interconnected, so that the frame components and the solar roof are stably installed, and the risk that the solar cell components fall off in the installation process is reduced.

The first structure a is provided with a mounting groove 110, the mounting groove 110 has a first opening at a side away from or adjacent to the second structure B, and the mounting groove 110 is used for accommodating at least an edge of the solar cell module 200.

The second structure B is provided with a fixed connection slot 130, the fixed connection slot 130 is adapted to accommodate the slider connection element 400, and the fixed connection slot 130 is adapted to allow the slider connection element 400 to move in the fixed connection slot 130 along the length direction (Z direction in the drawing) of the unit frame unit 100; a second opening is disposed at a side of the fixed connection slot 130 adjacent to or away from the first structure, and the second opening is suitable for allowing the slider connection element accommodated in the fixed connection slot 130 to connect with the fixed connection element through the second opening, so that the assembly frame unit 100 is connected with the fixed connection element.

In addition, the inner side of the groove wall edge of the fixed connection groove 130, on which the second opening is formed, is further provided with a limiting protruding rib 131 protruding towards the opposite groove wall, and the limiting protruding rib 131 extends along the length direction (Z direction in the drawing) of the assembly frame unit 100. Since the opening center line of the second opening is perpendicular to the opening center line of the first opening, the slider connector 400 can be connected to the fixed connector only in the direction perpendicular to the direction of the first opening, or in other words, in the direction perpendicular to the direction of the solar cell module 200. This allows the fastening connection to be at least partially blocked by the second structure B of the component border element 100 in a top view. In the installation mode of the prior art, the clamping type connecting piece is positioned above the frame assembly, so that the surface of the whole visual system is uneven, and the appearance is not attractive. In the component border unit 100 of the present embodiment, since the fixed connection member is at least partially blocked and hidden by the second structure B of the component border unit 100, the fixed connection member cannot be seen from the top view, so that the component border unit is flat and smooth in overall view and more beautiful in appearance.

In the prior art frame assembly, the assembly frame unit includes a mounting groove and a coupling groove. The mounting groove is used for being assembled with the solar cell module, and the connecting groove is used for being inserted into the connecting piece to be connected with other module frame units. The solar cell module with the frame module installed is usually installed and fixed on a structure to be installed by using clamping type connecting pieces and bolts. In the installation mode of the color steel tile roof, the structure to be installed is the color steel tile roof; because the solar module is close with the top surface distance on various steel tile roof, lacks operating space, so be clamping type's connecting piece mounting means in the installation of various steel tile roof usually, use the side of the clamping type's of aluminium system connecting piece centre gripping subassembly frame unit, cooperation bolt is fixed solar module on the top surface on various steel tile roof. However, in this installation method, the clamping-type connecting member may be deformed or have an unreasonable tolerance setting during production and transportation, or a worker may perform an operation error individually, which may cause the clamping-type connecting member and the frame assembly to be attached poorly, and the clamping-type connecting member may be separated from the frame assembly in windy weather, which may cause unstable installation of the solar cell assembly, and may cause the solar cell assembly to drop and be damaged.

In the module frame unit 100 of the present embodiment, the first structure a is provided with a mounting groove 110, the second structure B is provided with a fixed connecting groove 130, and one side of the mounting groove 110 departing from or adjacent to the fixed connecting groove 130 is provided with a first opening, so that the mounting groove 110 can accommodate the edge of the solar cell module 200, and the module frame unit 100 is mounted on the edge of the solar cell module 200. The fixed coupling groove 130 is adapted to receive the slider coupling member 400, and the slider coupling member 400 is adapted to move in the fixed coupling groove 130 along the length direction (Z direction in the drawing) of the unit frame unit 100. And a second opening is opened at a side of the fixed connection slot 130 adjacent to or away from the first structure, and the slider connection member 400 accommodated in the fixed connection slot 130 is adapted to be connected to the fixed connection member through the second opening, so that the assembly frame unit 100 is fixed. In this way, when the module frame unit 100 is used, the sliding block connection part 400 may be disposed in the fixed connection slot 130 in advance, and the fixed connection between the module frame unit 100 and the fixed connection part may be achieved through the second openings of the sliding block connection part 400 and the fixed connection slot 130 which are disposed in advance and accommodated in the fixed connection slot 130. Therefore, the solar cell module is prevented from being fixedly installed in a clamping type connecting piece and bolt matching mode, and the frame module and the solar roof are stably installed. In addition, through the arrangement of the limiting convex ribs 131 protruding from the second opening edge toward the opposite side groove wall, the limitation of the slider connector 400 can be realized, the movement of the slider connector 400 in the fixed connection groove 130 is limited, and the slider connector 400 is prevented from being loosened in the fixed connection groove.

Specifically, in some embodiments, as shown in fig. 1 to 4, the third structure C of the assembly frame unit is provided with a frame connecting groove 120, and the frame connecting groove 120 is suitable for the frame connecting member 300 to be inserted so as to connect the plurality of assembly frame units 100 through the frame connecting member 300.

The third structure is adjacent to either the first structure or the second structure, or to both the first structure and the second structure. In the embodiment shown in fig. 1-4, the arrangement among the first structure a, the second structure B, and the third structure C may be:

as shown in FIG. 1, the first structure A and the second structure B are along the edge of the deviceThe frame units 100 are arranged in the height Y direction; the third structure C is located at the first structure A _a And a second structure B _a In between. The first structure a, the second structure B and the third structure C are of equal width.

Alternatively, as shown in fig. 2, the first structure a and the second structure B are arranged along the height direction Y; the third structure C and the first structure A are arranged along the width direction Y, and the third structure C and the second structure B are arranged along the height direction Y of the component frame unit. The first structure A and the third structure C are equal in height, and the sum of the widths of the first structure A and the third structure C is equal to the width of the second structure.

Alternatively, as shown in fig. 3, the first structure a and the third structure C are arranged in the width direction X; the second structure B is located between the first structure a and the third structure C. The first structure A, the second structure B and the third structure C are equal in height.

Alternatively, as shown in fig. 4, the first structure a and the second structure B are arranged along the width direction X; the third structure C is located between the first structure a and the second structure B. The first structure A, the second structure B and the third structure C are equal in height.

In addition, the arrangement of the component frame unit 100 shown in fig. 2 is compared with the arrangement of the component frame unit 100 shown in fig. 1, so that the overall height of the component frame unit is reduced. Thereby reducing the overall height of the solar cell module mounted with the module frame unit. Because the solar cell module provided with the module frame unit is vertically packaged during packaging and transportation, the packaging thickness of the solar cell module provided with the module frame unit can be reduced by the arrangement, and more solar cell modules provided with the module frame unit can be packaged in a single packaging process. The arrangement of the module frame unit 100 shown in fig. 3 and the arrangement of the module frame unit 100 shown in fig. 4 can further reduce the overall height of the module frame unit compared to the arrangement of the module frame unit 100 shown in fig. 2, thereby further reducing the packing thickness of the solar cell module mounted with the module frame unit.

Furthermore, a pair of limiting protrusions are disposed on the inner side surface of the connecting groove 130 corresponding to the second opening, and the positions of the limiting protrusions respectively correspond to the opening edges of the second opening. For limiting the slider coupling member 400 when the slider coupling member 400 is received in the coupling groove 130.

Referring also to fig. 5 and 6, the component border unit 100 has first and second opposite end surfaces 140 and 150 along the length direction Z. An included angle between the first end surface 140 and an outer side wall of the side, away from the first opening, of the component frame unit 100 is a first included angle α 1, and the first included angle α 1 may be an acute angle or a right angle; the included angle between the second end surface 150 and the outer sidewall of the side of the assembly frame unit 100 away from the first opening is a second included angle α 2, and the second included angle α 2 may be an acute angle or a right angle.

Example 2

Referring to fig. 8 to 13, the present embodiment further provides a frame assembly for surrounding and connecting the edge of the solar cell module 200 and mounting the solar cell module 200 to a structure to be mounted, including:

a plurality of the component border units 100 provided in embodiment 1 above;

a plurality of frame connectors 300; the bezel coupler 300 is adapted to be inserted into the bezel coupler slot 120; adjacent component border units are adapted to be connected by border connectors 300.

Thus, the solar cell module 200 can be packaged by arranging the plurality of module frame units on the side of the solar cell module 200, so that the solar cell module 200 can be protected.

In addition, the frame component further comprises:

a plurality of slider connectors 400, the slider connectors 400 being adapted to be inserted into the fixed coupling grooves 130 of the component frame unit 100, and the slider connectors 400 inserted into the fixed coupling grooves 130 being adapted to slide along the length direction (Z direction in the drawing) of the component frame unit 100.

And the fixed connecting pieces 500 are suitable for being connected and fixed with the sliding block connecting piece 400, and are suitable for being connected and fixed with the structure to be installed while being connected with the sliding block connecting piece 400. In this way, the solar cell module 200 mounted with the module frame unit 100 may be fixedly mounted to the structure to be mounted through the fixing connector 500.

Further, referring to fig. 10, the slider connector 400 includes a slider portion 410 and a projection 420 to a surface of the slider portion; the slider portion 410 is adapted to fit into the fixed connection slot 130; the protrusion 420 is adapted to protrude out of the fixed connection groove 130 through the second opening when the slider part 410 is inserted into the connection groove 110, and a portion of the protrusion protruding out of the fixed connection groove 130 is adapted to be fixedly connected with the fixed link 500.

In this way, when the module frame unit 100 in the frame module is used, the sliding block connection part 400 may be disposed in the fixed connection slot 130 in advance, and the fixed connection between the module frame unit 100 and the fixed connection part 500 is achieved through the second openings of the sliding block connection part 400 and the fixed connection slot 130 which are disposed in advance and accommodated in the fixed connection slot 130. Thereby avoided using the connecting piece of centre gripping type and bolt fit's mode to install the fixed mounting of the solar module 200 of subassembly frame unit 100, therefore can reduce the risk that like prior art appears in the installation because of the connecting piece tolerance of centre gripping type or personnel misoperation cause the connecting piece of centre gripping type and the laminating of subassembly is not firm and causes solar module 200 to drop.

Further, the width dimension of the slider portion 410 is smaller than or equal to the width dimension of the fixed connection slot 130 and larger than the width dimension of the second opening; the width dimension of the protrusion 420 is equal to or less than the width dimension of the second opening. In this way, since the width of the sliding block portion 410 is smaller than or equal to the width of the fixed connection slot 130 and larger than the width of the second opening, the sliding block portion 410 of the sliding block connection element 400 can be supported by the slot wall on the side of the second opening in the fixed connection slot 130 to slide along the length direction of the frame unit 100 in the fixed connection slot 130. Thus, before the module frame unit 100 is mounted on the edge of the solar cell module 200, the slider connector 400 is inserted into the fixed connection slot 130 from the side of the frame unit 100, and is slid in the longitudinal direction by the slider connector to move to a proper position for subsequent mounting without falling off from the second opening. The width dimension of the protrusion 420 is less than or equal to the width dimension of the second opening, so that the protrusion 420 can protrude out of the second opening to facilitate connection with the fixed connector 500.

In a specific application, referring to fig. 8 and 9, a plurality of module frame units 100 are respectively mounted at the edges of the solar cell module 200, and adjacent module frame units 100 are connected by a frame connector 300. The frame connecting member 300 has two connecting ends connected together, and an included angle is formed between the two connecting ends. One coupling end is inserted into the coupling groove 130 of one module frame unit 100 and the other coupling end is inserted into the coupling groove 130 of the other module frame unit 100, thereby coupling the adjacent module frame units 100. And finally, the frame assembly surrounds the whole edge of the solar cell assembly 200.

Furthermore, in some other embodiments, the top view of the solar cell module 200 may not be rectangular, such as triangular, parallelogram, or other polygonal shapes. Meanwhile, the frame component may include a component frame unit with a number less than or equal to the number of the side edges of the solar cell component 200, and does not surround all the side edges of the solar cell component 200. For example, when the top view of the solar cell module 200 is rectangular, it may surround one edge of the solar cell module rather than all four edges. Meanwhile, the included angle between the two connecting ends of the frame connecting piece 300 can be a corresponding proper angle between 1 degree and 180 degrees. And when the length of one assembly frame unit is far smaller than the length of the single side edge of the solar cell assembly, a plurality of assembly frame units can be connected into a whole through connecting pieces and are jointly installed on the single side edge of the solar cell assembly, and a plurality of pairs of assembly frame units are jointly installed on the opposite two side edges of the solar cell assembly to complete the encapsulation of the solar cell assembly.

In some embodiments, as shown in fig. 7 and 10, the slider portion 410 of the slider connector 400 is respectively provided with a limiting groove 411 at both sides of the protrusion portion 420, and the concave direction of the limiting groove 411 is opposite to the protruding direction of the protrusion portion 420; the width of the stopper groove 411 is greater than or equal to the width of the rib 131. Referring to fig. 10, the slider connector 400 thus configured, when received in the fixed coupling groove 130 having the protruding ribs 131, can limit the slider connector 400 by the limit recesses 411 cooperating with the protruding ribs 131. The movement of the slider coupling member in the fixed coupling groove 130 is restricted to prevent the slider coupling member 400 from being released in the fixed coupling groove 130.

Further, the distance from the bottom of the limit groove 111 of the slider part 410 to the top surface of the slider part 410 is smaller than the difference between the height of the inner wall of the connecting groove 130 and the height of the limit protrusion 131; the distance from the top of the spacing groove 411 of the slider part 410 to the top surface of the slider part 410 is smaller than the height of the inner wall of the connecting groove 130.

In the embodiment shown in fig. 10, the slider connector 400 may be a slider nut. The slider nut has a threaded coupling hole 430 that extends through the slider portion 410 and the protrusion portion 420. Referring to fig. 11 and 12, the slider nut is adapted to be coupled to the fixed coupling member 500 through the threaded coupling hole 430 by the locking coupling member 600.
