Specifically, at least one mounting groove 11 is formed on the bracket body 1, both ends in the length direction of the mounting groove 11 are opened, and the frame 200 of the photovoltaic module is suitable for being fitted in the mounting groove 11. The pressing member 2 is formed with a pressing groove 21, at least one side of the pressing groove 21 in a length direction of the mounting groove 11 is opened to form a first opening 211, and a side wall of the mounting groove 11 and a side edge of the bezel 200 are adapted to be pressed in the pressing groove 21 through the first opening 211.

For example, in the examples of fig. 1 to 7, the mounting grooves 11 are formed on both sides of the bracket body 1 in the width direction, so that two adjacent photovoltaic modules can be connected to the same bracket body 1, approximately half of the mounting bracket 100 can be saved, and the cost of the photovoltaic system can be reduced. Both ends of the pressing groove 21 in the length direction of the mounting groove 11 are opened. During the installation, can install photovoltaic module's frame 200 earlier in corresponding mounting groove 11, later, along the length direction removal of mounting groove 11 and compress tightly piece 2 to pass first opening 211 with the lateral wall of mounting groove 11 and the side of frame 200 and compress tightly in compressing tightly the groove 21. Therefore, compared with the traditional photovoltaic system, an operator can install the photovoltaic module on the mounting bracket 100 quickly, the mounting mode is simple, and the operation is convenient, so that the labor cost can be reduced, and the mounting period of the photovoltaic system is shortened.

The clamping assembly 3 comprises two clamping members 31, one ends of the two clamping members 31 are respectively connected with two ends of the bracket body 1, the other ends of the two clamping members 31 are positioned below the bracket body 1, and the other ends of the two clamping members 31 are detachably connected. Thus, the mounting bracket 100 can be fixed at a certain position by the clamping assembly 3 to ensure the stability of the position of the photovoltaic assembly, so that the reliability of the photovoltaic system can be ensured. Wherein, by detachably connecting the other ends of the two clamping members 31, the quick mounting and dismounting of the mounting bracket 100 can be realized, and the dismounting efficiency of the mounting bracket 100 can be improved.

According to the mounting bracket 100 for a photovoltaic module of the embodiment of the present invention, by forming the pressing groove 21 on the pressing member 2, at least one side of the pressing groove 21 in the length direction of the mounting groove 11 is opened to form the first opening 211, the side wall of the mounting groove 11 and the side edge of the bezel 200 are adapted to be pressed in the pressing groove 21 through the first opening 211, and the above-mentioned other ends of the two clamping members 31 of the clamping assembly 3 are detachably connected. Therefore, an operator can install the photovoltaic module on the mounting bracket 100 quickly, the mounting mode is simple, and the operation is convenient, so that the labor cost can be reduced, the mounting period of the photovoltaic system can be shortened, and the dismounting efficiency of the photovoltaic system can be improved.

According to some embodiments of the present invention, referring to fig. 2 to 7, the bracket body 1 includes a bracket bottom wall 12 and two bracket side walls 13, the two bracket side walls 13 are respectively connected to both sides of the bracket bottom wall 12 in the width direction and extend upward, and a first portion of a free end of at least one bracket side wall 13 is bent in a U-shape toward the other bracket side wall 13 to form the mounting groove 11. Through designing mounting groove 11 into the U-shaped for mounting groove 11's simple structure, convenient processing, photovoltaic module along the motion of upper and lower direction can be injectd to two lateral walls on the upper and lower direction of mounting groove 11 simultaneously, thereby can guarantee the stability of photovoltaic module's position.

A second portion of the free end of at least one of the frame side walls 13 is bent away from the other frame side wall 13 to form a flange 131, the flange 131 and the side edges being adapted to be pressed through the first opening 211 into the pressing groove 21. For example, in the example of fig. 5 to 7, both ends in the length direction of each bracket side wall 13 are formed with flanges 131, and the flanges 131 extend in a direction away from the center of the bracket body 1. When the photovoltaic module is installed, the flanges 131 and the side edges of the frame 200 are pressed in the corresponding pressing grooves 21 through the corresponding first openings 211 of the pressing members 2, so as to firmly fix the photovoltaic module on the mounting bracket 100. Therefore, on one hand, the contact area between the side wall 13 of the bracket and the frame 200 of the photovoltaic module can be increased by the flanging 131, so that the photovoltaic module can be stably installed in the installation groove 11 of the bracket body 1; on the other hand, the structural strength of the bracket body 1 can be improved, so that the load capacity of the bracket body 1 can be improved.

In some optional embodiments, an included angle between a side wall of the mounting groove 11 far from the flange 131 and an inner wall of the mounting groove 11 is α, where α satisfies: alpha is less than 90 degrees. When alpha is larger than 90 degrees, the included angle between the side wall of the mounting groove 11 far away from the flange 131 and the inner wall of the mounting groove 11 is larger, after mounting, a certain gap exists between the top of the frame 200 of the photovoltaic module and the side wall of the mounting groove 11 far away from the flange 131, and the frame 200 of the photovoltaic module may be separated from the mounting groove 11, which affects the stability of the position of the photovoltaic module. Thus, by making α satisfy: alpha is less than 90 degrees, after the photovoltaic module is inserted into the corresponding mounting groove 11 along the length direction of the bracket body 1, the side wall of the mounting groove 11 far away from the flanging 131 can be stopped against the top of the frame 200, so that the frame 200 of the photovoltaic module is more stably matched in the mounting groove 11, and the frame 200 can be prevented from being separated from the mounting groove 11.

According to some embodiments of the present invention, as shown in fig. 5 to 7, first portions of free ends of both the bracket side walls 13 are bent in a U-shape toward the other bracket side wall 13 to form the mounting grooves 11, respectively. Wherein, the opening of two mounting grooves 11 is all opened towards the direction of keeping away from each other to make two photovoltaic module of simultaneous installation on the same support body 1, and then can reduce the quantity of installing support 100 among the photovoltaic system, reduce photovoltaic system's cost. The inner walls of the mounting grooves 11 are connected to each other to make the structure of the mounting bracket 100 more compact. Alternatively, the inner walls of the two mounting grooves 11 opposite to each other may be integrally formed; or, when the support body 1 is a sheet metal part, the inner walls of the two installation grooves 11 opposite to each other can be connected with each other in a welding mode or a riveting mode.

In some alternative embodiments, the mounting bracket 100 further includes at least one grounding member 4, and the grounding member 4 is snapped into the ends of the two mounting slots 11. Referring to fig. 4 and 5 in combination with fig. 13 and 14, the mounting bracket 100 may include two ground members 4, the two ground members 4 being respectively located at both ends of the mounting groove 11 in the length direction. Each grounding piece 4 may include a body 41 and a bending portion 42, wherein a slot 411 is formed on the body 41, the slot 411 is communicated with one end of the body 41, and the other end of the body 41 is connected with the bending portion 42. When the grounding piece is installed, the side wall of the installation groove 11 adjacent to the turned edge 131 is clamped between the body 41 and the bent part 42, the inner wall of the installation groove 11 passes through the slot 411 of the grounding piece 4, and one end of the inner wall of the installation groove 11 is abutted against the inner wall of the slot 411, so that the grounding piece 4 is firmly installed on the bracket body 1. Thus, the grounding member 4 can ground the current on the mounting bracket 100, thereby ensuring the safety of the mounting bracket 100.

Two grounding members 4 are shown in fig. 4 and 5 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to other number of grounding members 4, which also falls within the protection scope of the present invention.

Alternatively, the distance between the bent portion 42 and the body 41 gradually decreases in the direction from the connection of the bent portion 42 and the body 41 toward the center of the body 41.

The open side of the first compression part 22 and the spacing post 24 are both located on the side of the compression member 2 adjacent to the bracket side wall 13. During installation, the side of the frame 200 of the flanging 131 and the photovoltaic module passes through the first opening 211 to be matched in the pressing groove 21, and meanwhile, the limiting column 24 passes through the second opening 1321 to be matched in the limiting groove 132, and pushes the pressing part 2 along the length direction of the limiting groove 132 until the limiting column 24 is stopped against the inner wall of the limiting groove 132. Therefore, the positioning and locking of the pressing piece 2 are realized, so that the photovoltaic module is reliably connected to the support body 1, and meanwhile, the assembly efficiency of the photovoltaic system can be effectively improved. In addition, through the cooperation of spacing post 24 and spacing groove 132, can inject the removal of compressing tightly piece 2 in the thickness direction of support lateral wall 13, guaranteed the stability of compressing tightly the position of piece 2.

Further, referring to fig. 7, a stopper structure is provided between the lower end of the second pressing portion 23 and the corresponding bracket sidewall 13 to space the lower end of the second pressing portion 23 and the corresponding bracket sidewall 13 from each other. From this, compress tightly 2 installation back, the lower extreme that the second compressed part 23 can be by backstop structure jack-up, and the spacing post 24 that compresses tightly 2 this moment is the fulcrum, and the top that the first compressed part 22 can be towards turn-ups 131 direction downstream in order to compress tightly in compressing tightly the groove 21 with the side of turn-ups 131 and photovoltaic module's frame 200, further guarantees the stability in photovoltaic module's position.
