Detailed Description

Embodiments of the present invention are described in detail below, the embodiments described with reference to the drawings are exemplary, and an angle brace 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 5.

For example, referring to fig. 3 and 5, the bezel 200 includes a first bezel 201 and a second bezel 202 adjacent to each other, the first bezel 201 and the second bezel 202 have substantially the same structure, and the first bezel 201 and the second bezel 202 may have different lengths. Taking the first frame 201 as an example for illustration, the first frame 201 may include a fixing portion 203 and a supporting portion 204 connected to each other, the fixing portion 203 is used for fixing a photovoltaic body of the photovoltaic module, specifically, a mounting groove 2031 for accommodating an edge of the photovoltaic body is formed on the fixing portion 203, a side (e.g., a left side in fig. 5) of the mounting groove 2031 facing a center of the photovoltaic module is open, and the edge of the photovoltaic body may extend into and fit in the mounting groove 2031 through the open side of the mounting groove 2031. The support portion 204 is used to support the fixing portion 203 and the photovoltaic body. The supporting portion 204 may have a receiving cavity 2041 formed thereon to facilitate connection of the first frame 201 and the second frame 202. In addition, the first frame 201 and the second frame 202 can reduce the weight and the material while ensuring the fixation and protection of the photovoltaic body, thereby reducing the cost.

Alternatively, the fixing portion 203 and the supporting portion 204 of the first frame 201 may be integrally formed by bending a steel plate, but are not limited thereto. It will be appreciated that the bezel 200 may be other than the configuration shown in fig. 3. In the following description of the present application, the corner connector 100 is illustrated by taking the connection between the first frame 201 and the second frame 202 in fig. 3 as an example.

As shown in fig. 1 and 2, the corner brace 100 according to the embodiment of the first aspect of the present invention includes a body 1, a first fitting portion 2, and a second fitting portion 3.

Specifically, one end of the first fitting portion 2 is connected to one side of the body 1, and the other end of the first fitting portion 2 extends in a first direction (e.g., up-down direction in fig. 1). For example, in the example of fig. 1, the one end of the first fitting portion 2 is a lower end of the first fitting portion 2, the other end of the first fitting portion 2 is an upper end of the first fitting portion 2, and the lower end of the first fitting portion 2 is connected to the top surface of the body 1. Thus, when the corner brace 100 is connected to the first frame 201, the first engaging portion 2 can extend into the receiving cavity 2041 of the first frame 201 and be connected to the first frame 201.

One end of the second fitting portion 3 is connected to the other side of the body 1, and the other end of the second fitting portion 3 extends in a second direction (e.g., left-right direction in fig. 1), the first direction being perpendicular to the second direction. For example, in the example of fig. 1, the one end of the second fitting portion 3 is a left end of the second fitting portion 3, the other end of the second fitting portion 3 is a right end of the second fitting portion 3, and the left end of the second fitting portion 3 is connected to a side surface of the body 1. With such an arrangement, the plane where the first matching portion 2 is located and the plane where the second matching portion 3 is located are perpendicular to each other, and when the first frame 201 and the second frame 202 are integrally connected by using the corner connector 100, the first matching portion 2 can be matched in the accommodating cavity 2041 of the first frame 201, and the second matching portion 3 can be matched in the accommodating cavity 2041 of the second frame 202, so as to connect the first frame 201 and the second frame 202. Therefore, the assembly operation of the first frame 201, the second frame 202 and the corner brace 100 is simple, and the assembly efficiency of the frame 200 can be improved.

A side surface of the body 1 away from the second fitting portion 3 protrudes a side surface of the first fitting portion 2 away from the second fitting portion 3 and defines a first fitting groove 21 with a side surface of the first fitting portion 2 away from the second fitting portion 3, and a side of the first fitting groove 21 facing the other end of the first fitting portion 2 in the first direction is open. For example, in the example of fig. 1 and 2, the left side surface of the body 1 protrudes from the left side surface of the first fitting portion 2, and a first fitting groove 21 is defined between the left side surface of the body 1 and the left side surface of the first fitting portion 2, and the top of the first fitting groove 21 is open. And/or, a side surface of the body 1 far away from the first matching part 2 protrudes out of a side surface of the second matching part 3 far away from the first matching part 2 and defines a second matching groove 31 with a side surface of the second matching part 3 far away from the first matching part 2, and one side of the second matching groove 31 facing to the other end of the second matching part 3 along the second direction is opened. For example, in the example of fig. 1 and 2, the bottom surface of the body 1 protrudes from the bottom surface of the second fitting portion 3, and a second fitting groove 31 is defined between the bottom surface of the body 1 and the bottom surface of the second fitting portion 3, and the right side of the first fitting groove 21 is open.

The setting of the corner brace 100 includes the following three cases:

a first fitting groove 21 (not shown) is defined between a side surface of the first, only body 1 remote from the second fitting portion 3 and a side surface of the first fitting portion 2 remote from the second fitting portion 3. A second fitting groove 31 (not shown) is defined between a side surface of the second, only body 1 remote from the first fitting portion 2 and a side surface of the second fitting portion 3 remote from the first fitting portion 2. Thirdly, a first fitting groove 21 is defined between a side surface of the body 1 away from the second fitting part 3 and a side surface of the first fitting part 2 away from the second fitting part 3, while a second fitting groove 31 is defined between a side surface of the body 1 away from the first fitting part 2 and a side surface of the second fitting part 3 away from the first fitting part 2 (as shown in fig. 1 and 2).

So configured, when the first matching portion 2 is matched in the accommodating cavity 2041 of the first frame 201 and the second matching portion 3 is matched in the accommodating cavity 2041 of the second frame 202, as shown in fig. 3, the edge of the side wall of the first frame 201 far away from the opening side of the mounting groove 2031 can be placed in the first matching groove 21, and the edge of the side wall of the second frame 202 far away from the opening side of the mounting groove 2031 can be placed in the second matching groove 31. Therefore, by arranging the first matching groove 21 and the second matching groove 31, a part of the edge of the frame 200 can be wrapped in the first matching groove 21 and the second matching groove 31, so that the contact between the edge of the frame 200 and a user is reduced, and the potential safety hazard in the assembling and using processes of the frame 200 is reduced. Moreover, the outer peripheral surface of the frame 200 is flat, and the appearance of the frame 200 is improved.

According to the utility model discloses angle sign indicating number 100, through setting up first cooperation groove 21 and/or second cooperation groove 31, can hide the edge part that is more hard and sharp of frame 200 effectively, reduced the assembly of frame 200 and the potential safety hazard to the user in the use, also can reduce the contact of other parts in the edge of frame 200 and the external environment condition to can improve the safety in utilization of frame 200, and then improve photovoltaic module's safety in utilization. Moreover, the corner brace 100 can also protect the edge of the frame 200, which is beneficial to the use of the frame 200. In addition, the aesthetic degree of the frame 200 is improved, and the use experience of a user is improved.

Further, both sides of the first fitting groove 21 in the third direction (for example, the front-rear direction in fig. 1) are open; and/or both sides of the second fitting groove 31 in the third direction are opened, and the third direction, the first direction and the second direction are orthogonal.

The arrangement of the first engagement groove 21 and the second engagement groove 31 includes the following three cases: first, only two sides of the first fitting groove 21 along the third direction are opened (not shown in the figure), so that while the protective effect of the first fitting groove 21 on the edge of the first frame 201 is ensured, the length of the side face, far away from the second fitting part 3, of the body 1 in the third direction can be reduced, the material is saved, and the production cost of the corner brace 100 is reduced. Second, only two sides of the second fitting groove 31 along the third direction are opened (not shown), thereby, while ensuring the protective effect of the second fitting groove 31 on the edge of the second frame 202, the length of the side surface of the body 1 far away from the first fitting part 2 in the third direction can be reduced, thereby saving material and reducing cost. Both sides of the third, first fitting groove 21 in the third direction are open, and both sides of the second fitting groove 31 in the third direction are open (as shown in fig. 1 and 2). So set up, when guaranteeing the guard action of first cooperation groove 21 to the edge of first frame 201 to and the guard action of second cooperation groove 31 to the edge of second frame 202, can reduce the length of body 1 in the third direction, can material saving, reduce cost, the production and processing of body 1 is also comparatively convenient.

According to some embodiments of the present invention, referring to fig. 1 and 2, the first fitting part 2 is formed with a plurality of first through holes 22; and/or the second fitting part 3 is formed with a plurality of second through holes 32. In the description of the present invention, "a plurality" means two or more. The following three cases are included here: first, only the first fitting portion 2 is formed with a plurality of first through holes 22 (not shown); a second, only second fitting portion 3 is formed with a plurality of second through holes 32 (not shown); the third and first fitting parts 2 are formed with a plurality of first through holes 22, and the second fitting part 3 is formed with a plurality of second through holes 32 (as shown in fig. 1 and 2).

For example, in the example of fig. 1, each of the plurality of first through holes 22 and the plurality of second through holes 32 extends in the third direction, each of the first through holes 22 penetrates through the front surface and the rear surface of the first fitting part 2, and each of the second through holes 32 penetrates through the front surface and the rear surface of the second fitting part 3. Therefore, the material of the first matching part 2 and the second matching part 3 can be reduced, and the production cost can be reduced. In addition, the weight of the first and second fitting parts 2 and 3 can be reduced, so that the corner brace 100 is more convenient to use. In addition, the first matching part 2 is easy to deform, and the matching of the corner brace 100 and the frame 200 is facilitated.

Alternatively, the plurality of first through holes 22 are arranged at intervals in the first direction; and/or, the plurality of second through holes 32 are arranged at intervals along the second direction. The following three cases are included here: first, only a plurality of first through holes 22 are arranged at intervals along the first direction (not shown in the figure), and therefore, the arrangement of the plurality of first through holes 22 is reasonable, and when the first matching part 2 is matched with the accommodating cavity 2041 of the first frame 201, the material of the first matching part 2 can be reduced to a great extent, and the production cost of the first matching part 2 is reduced. In addition, while the first fitting portion 2 is conveniently assembled with the first frame 201, the structural strength of the first fitting portion 2 may be ensured, so that the first fitting portion 2 may be fitted with the first frame 201 for a long time. And the second and only the second through holes 32 are arranged at intervals along the second direction (not shown in the figure), so that the arrangement of the second through holes 32 is reasonable, and the material of the second matching part 3 can be greatly reduced. In addition, while the second fitting portion 3 is conveniently assembled with the second rim 202, the structural strength of the second fitting portion 3 may be ensured, so that the second fitting portion 3 may be fitted with the second rim 202 for a long time. The third, plurality of first through holes 22 are arranged at intervals in the first direction, and the plurality of second through holes 32 are arranged at intervals in the second direction. For example, the example of fig. 1 and 2 shows two first through holes 22 and two second through holes 32, the two first through holes 22 being arranged at intervals in the first direction, and the two second through holes 32 being arranged at intervals in the second direction. Therefore, the arrangement of the first through holes 22 and the second through holes 32 is reasonable, the material of the corner brace 100 can be effectively reduced, and the production cost of the corner brace 100 is reduced. In addition, the corner brace 100 has certain structural strength, and the use of the corner brace 100 is facilitated. It should be noted that the number of the first through holes 22 and the second through holes 32 can be specifically set according to actual situations, so as to better meet practical applications.

Further optionally, referring to fig. 1 and fig. 2, two third through holes 11 are formed in the body 1, the third through holes 11 extend along a third direction, and each third through hole 11 penetrates through two side surfaces of the body 1 along the third direction. Thereby, the material of the body 1 can be reduced, the cost can be reduced, and the weight of the corner brace 100 can be further reduced. It should be noted that, one third through hole 11 or more than two third through holes 11 may also be provided according to actual requirements, so as to better meet practical applications.

According to some embodiments of the present invention, at least one of two sides of the first fitting part 2 in the second direction is provided with a first anti-slip structure 23; and/or, a second anti-slip structure 33 is provided on at least one of two side surfaces of the second fitting portion 3 in the first direction.

Here, the following three cases are included: a first anti-slip structure 23 (not shown) is provided on at least one of both side surfaces of the first, only first fitting portion 2 in the second direction. Thereby, friction between the first fitting portion 2 and the receiving cavity 2041 of the first frame 201 can be increased, so that the first fitting portion 2 and the first frame 201 are assembled more firmly. A second anti-slip structure 33 (not shown) is provided on at least one of both side surfaces of the second, only second fitting portion 3 in the first direction. Therefore, friction between the second matching part 3 and the accommodating cavity 2041 of the second frame 202 is increased, and the assembling relation between the second matching part 3 and the second frame 202 is strengthened. Third, a first anti-slip structure 23 is provided on at least one of two sides of the first matching part 2 in the second direction, and a second anti-slip structure 33 is provided on at least one of two sides of the second matching part 3 in the first direction (as shown in fig. 1 and 2). From this, the connection between first cooperation portion 2 and the first frame 201 is more fastened, and the connection between second cooperation portion 3 and the second frame 202 is also more fastened simultaneously to corner sign indicating number 100 is difficult for dropping from first frame 201 and second frame 202, and the assembly of corner sign indicating number 100 and frame 200 is more firm, and then is favorable to the long-time use of frame 200, has guaranteed the reliability that photovoltaic module used for a long time.

It should be noted that the accommodating cavity 2041 of the first fitting portion 2 and the first frame 201 may be in interference fit, and the accommodating cavity 2041 of the second fitting portion 3 and the second frame 202 is in interference fit, and no additional fastener is needed for fixing, so that the assembly efficiency is improved, and the connection cost of the frame 200 and the corner connector 100 can be further reduced.

Optionally, a first anti-slip structure 23 is provided on the side of the first mating part 2 adjacent to the second mating part 3; and/or the second anti-slip arrangement 33 is provided on the side of the second fitting part 3 adjacent to the first fitting part 2. Here, the following three cases are included: the first and second antiskid structures 23 are arranged on the side surface of the first matching part 2 adjacent to the second matching part 3; the second and the second antiskid structures 33 are arranged on the side surface of the second matching part 3 adjacent to the first matching part 2; thirdly, referring to fig. 1 and 2, the first anti-slip structure 23 is provided on a side of the first fitting part 2 adjacent to the second fitting part 3, and the second anti-slip structure 33 is provided on a side of the second fitting part 3 adjacent to the first fitting part 2.

For example, in the example of fig. 1 and 2, the first anti-slip structure 23 is disposed on the right side surface of the first matching portion 2, and thus, the right side surface of the first matching portion 2 can play an anti-slip role, and meanwhile, the left side surface of the first matching portion 2 can be sufficiently contacted with the inner wall of the accommodating cavity 2041 of the first frame 201, which is beneficial for the interference fit between the first matching portion 2 and the accommodating cavity 2041 of the first frame 201, so as to reduce the probability that the first matching portion 2 falls off from the first frame 201. Second anti-skidding structure 33 is established at the top surface of second cooperation portion 3, so sets up, and the top surface of second cooperation portion 3 can play anti-skidding effect, and the bottom surface of second cooperation portion 3 can be fully with the inner wall contact that holds chamber 2041 of second frame 202, is favorable to the interference fit that holds chamber 2041 of second cooperation portion 3 and second frame 202 to reduce the probability that second cooperation portion 3 dropped from second frame 202. Therefore, the corner brace 100 is not easy to fall off from the frame 200, and the corner brace 100 can be connected with the frame 200 for a long time, so that the normal use of the photovoltaic module is ensured. Meanwhile, the assembly operation of the corner brace 100 and the frame 200 is simple.

According to some embodiments of the present invention, the first anti-slip structure 23 comprises a plurality of first anti-slip teeth 231 arranged along a first direction, each first anti-slip tooth 231 extending obliquely along a direction towards a longitudinal center plane away from the first mating portion 2, towards the second mating portion 3; and/or, the second anti-slip structure 33 includes a plurality of second anti-slip teeth 331 arranged along the second direction, each second anti-slip tooth 331 extends obliquely along a direction away from the transverse center plane of the second matching portion 3 and towards the first matching portion 2.

The arrangement of the first anti-skid structure 23 and the second anti-skid structure 33 includes the following three conditions: the first and second anti-slip structures 23 include a plurality of first anti-slip teeth 231 arranged along a first direction, and each first anti-slip tooth 231 extends obliquely along a direction away from the longitudinal center plane of the first matching portion 2 and towards the second matching portion 3; the second and the second anti-slip structures 33 comprise a plurality of second anti-slip teeth 331 arranged along the second direction, and each second anti-slip tooth 331 extends obliquely along the direction far away from the transverse center plane of the second matching part 3 and along the direction towards the first matching part 2; third, with reference to fig. 1 and 2, the first anti-slip structure 23 includes a plurality of first anti-slip teeth 231 arranged along the first direction, each first anti-slip tooth 231 extends obliquely along the direction away from the longitudinal center plane of the first matching portion 2 and along the direction toward the second matching portion 3, and the second anti-slip structure 33 includes a plurality of second anti-slip teeth 331 arranged along the second direction, each second anti-slip tooth 331 extends obliquely along the direction away from the transverse center plane of the second matching portion 3 and along the direction toward the first matching portion 2.

For example, in the example of fig. 1 and 2, each of the first plurality of cleats 231 and the second plurality of cleats 331 extends in a third direction, each first cleat 231 is inclined downwardly in the second direction, and each second cleat 331 is inclined leftwardly in the first direction. Therefore, the inner wall of the accommodating cavity 2041 of the first frame 201, which is adjacent to the first anti-slip tooth 231, has greater resistance to the first anti-slip tooth 231, so that the connection relationship between the first matching part 2 and the first frame 201 is strengthened, and the connection can be more secure, and meanwhile, the inner wall of the accommodating cavity 2041 of the second frame 202, which is adjacent to the second anti-slip tooth 331, also has greater resistance to the second anti-slip tooth 331, so that the connection between the corner brace 100 and the frame 200 is more secure. In addition, first anti-skidding tooth 231 and second anti-skidding tooth 331's simple structure, processing is convenient, can effectively improve the production efficiency of angle sign indicating number 100. It should be noted that the number and the inclination angle of the first anti-slip tooth 231 and the second anti-slip tooth 331 can be specifically set according to actual situations, so as to better meet practical applications.

According to some embodiments of the present invention, referring to fig. 1 and 2, the other end of the first fitting portion 2 is formed with a first guide structure 24, and a cross-sectional area of the first guide structure 24 is gradually reduced from the one end of the first fitting portion 2 toward the other end of the first fitting portion 2; and/or, a second guide structure 34 is formed on the other end of the second matching part 3, and the cross-sectional area of the second guide structure 34 is gradually reduced from the one end of the second matching part 3 to the other end of the second matching part 3.

The arrangement of the first guide structure 24 and the second guide structure 34 described above includes the following three cases:

the other end of the first and second fitting portions 2 is formed with a first guide structure 24.
