As shown in fig. 1 and 2, the corner brace a includes a first connecting arm and a second connecting arm connected to the first connecting arm, and the first connecting arm and the second connecting arm both include: receive frame body B's extrusion to produce elastic deformation in order to form the deformation portion 10 that supports the top with at least a part of frame body B inner wall D, deformation portion 10 forms the first connecting portion 20 that supports the top with frame body B inner wall D when producing elastic deformation, deformation portion 10 forms the second connecting portion 30 that supports the top with frame body B inner wall D when producing elastic deformation, deformation takes place because of the extrusion effect that receives frame body B when deformation portion 10 inserts in frame body B's the hole, deformation portion 10 takes place to warp the back, can make angle sign indicating number A inseparabler with frame body B's cooperation.

As shown in fig. 2 and 3, the deformation portion 10 is disposed between the first connection portion 20 and the second connection portion 30. The corner brace is preferably made of a non-metal material, and the non-metal material is preferably made of a polyurethane composite material.

As shown in fig. 2 and 3, the height H of the first connecting arm and the second connecting arm is greater than the height of the inner hole of the frame body B, so that when the first connecting arm or the second connecting arm is inserted into the frame body B, the deformation portion 10 is elastically deformed by the extrusion of the frame body B, and the deformation portion 10 is urged to abut against the inner wall D of the frame body B. Preferably, when the deformation portion 10 is elastically deformed, the elastic force presses the first connection portion 20 and the second connection portion 30, so that the first connection portion 20 and the second connection portion 30 respectively abut against the inner wall D.

As shown in fig. 2 and 3, in the present embodiment, one deformation portion 10 is preferably adopted, the deformation portion 10 includes an arc portion, and an arc adopted by the arc portion preferably adopts a minor arc, so that the deformation portion 10 is easily deformed when being pressed by the frame body B.

As shown in fig. 2 and 3, the first connecting arm and the second connecting arm further include a top portion 20a that forms a top with the inner wall D of the frame body B, the top portion 20a is disposed at one end of the first connecting portion 20, and the strength of the corner connector itself is further increased by the top portion 20 a.

The first connecting arm and the second connecting arm further include a locking portion 31 disposed at one end of the second connecting portion, the locking portion 31 is a protrusion engaged with the mounting portion of the bezel body B, for example, when the mounting portion on the bezel body B is an opened mounting hole, the locking portion 31 is inserted into the mounting hole. For another example, when the mounting portion is a surface, the locking portion 31 is a plurality of teeth arranged at intervals, and the engagement between the teeth and the surface is kept stable by the friction force between the teeth and the surface.

As shown in fig. 2 and 4, the frame body B includes a connection member 40 and a support member 50, the support member 50 includes a first extension portion 50a and a second extension portion 50B, one end of the first extension portion 50a intersects with one end of the second extension portion 50B, so that the cross-section of the support member 50 is L-shaped, the other end of the first extension portion 50a is fixed to one end of the connection member 40, the other end of the second extension portion 50B is a free end, a slot 60 for installing the solar cell panel C is formed between the support member 50 and the connection member 40, and a protrusion 50f for preventing an adhesive in the slot 60 from overflowing to the outside of the slot 60 when the solar cell panel C is installed is provided on the free end 50e of the second extension portion 50B or the first side wall 50C facing the connection member 40.

As shown in fig. 2 and 4, in the present embodiment, only the protrusion 50f is provided at the free end 50e of the second extension portion 50b, when the end of the solar cell panel C is inserted into the slot 60, the end of the solar cell panel C is clamped between the protrusion 50f and the second side wall surface 50g of the connecting member 40, since the protrusion 50f protrudes from the first side wall 50C of the supporting member 50, a gap is formed between the end of the solar cell panel C and the first side wall 50C, due to the gap, an amount of adhesive injected into the slot 60 is prevented from overflowing, and due to the protrusion 50f, the adhesive overflowing is prevented from being blocked. Thereby the reliability that photovoltaic group can be installed with the frame has been increased.

As shown in fig. 2 and 4, at least a portion of the first sidewall 50c forms an angle with the longitudinal direction of the second extension portion 50b to enlarge the volume of the slot 60, and a preferred structure manner of the angle formed by at least a portion of the first sidewall 50c with the longitudinal direction of the second extension portion 50b is: the wide portion of the portion from the middle of the second extension portion 12 to one end of the second extension portion 50b is gradually reduced. At least a portion of the second sidewall surface 50g of the connecting member 40 facing the second extension 50b forms an angle with the longitudinal direction of the connecting member 40 to enlarge the volume of the insertion groove 60. The angle is also formed by gradually reducing the wall thickness of a portion of the connecting member 40. By enlarging the volume of the insertion groove 60, it is easier to prevent the adhesive from overflowing to the outside of the insertion groove 60, thereby ensuring the adhesion between the solar cell panel C and the connection member 40 and the support member 50.

As shown in fig. 2 and 4, a portion of the second extension portion 50b facing the first sidewall 50C of the connection member 40 is recessed toward the second extension portion 50b to form an overflow groove 50d for receiving the adhesive pressed by the solar cell panel C. One side of the glue overflow groove 50d is a protrusion 50f, preferably, the protrusion 50f is a part of the glue overflow groove 50d, one end of the protrusion 50f is located at the outer side of the notch of the glue overflow groove 50d, and the length of the protrusion 50f is greater than the depth of the glue overflow groove 50d, so that after the adhesive enters the glue overflow groove 50d, the adhesive does not overflow to the outside of the slot 60, and then the adhesive entering the glue overflow groove 50d is stored in the glue overflow groove 50d under the extrusion of the solar cell panel C, and the adhesive is used for bonding and fixing the solar cell panel C and the second extending part 50 b. Obviously, the utility model discloses after having add excessive gluey groove 50d, can accept more binder.
