Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] In addition, although the terms used in the present utility model are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present utility model may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the present description. In addition, it is required to understand the present utility model not only by the actual terms used, but also by the meaning implied by each term.

[0033] It should be understood that when a component is referred to as "on another component", "connected to another component", "coupled to another component", or "in contact with another component", it can be directly on, connected to, or coupled to, or in contact with the other component, or there may be an intervening component. In contrast, when a component is referred to as "directly on another component", "directly connected to", "directly coupled to", or "directly in contact with" another component, there is no intervening component.

[0034] The photovoltaic module fixing device provided by the embodiments of the present utility model can realize the fixed connection of the photovoltaic module and the target device together. The target device can be a C-shaped steel, a color steel tile, etc. That is, the fixing device provided by the embodiments of the present utility model can be applicable to a variety of scenarios. Please refer to Figures 1-3 , the fixing device 100 of the embodiments of the present utility model includes a first component 110 and a second component 120. The first component 110 includes an upper limiting plate 111 and a bottom plate 112. The upper limiting plate has opposite first side (the left side in the figure) and second side (the right side in the figure). The bottom plate 112 is connected to the first side of the upper limiting plate 111, so as to form a limiting groove 113 for inserting the frame of the photovoltaic module with the upper limiting plate 111. The fixing device 100 can be inserted along the bottom plate 112 into the supporting bottom plate 201 (also known as the C surface) of the frame 200 of the photovoltaic module, as Figure 4 shown. Preferably, please refer to Figure 2 , the slot width of the limiting groove 113 ( Figure 2The vertical dimension (less than the width of the bottom of the groove, especially gradually narrowing from the notch to the bottom of the groove, so that the support bottom plate 201 of the photovoltaic module frame 200 is fixed after being inserted).

[0035] Optionally, one or more puncture points 111a are provided on the upper limit plate 111, and the puncture points 111a protrude toward the side where the bottom plate 112 is located, improving the fixing strength and puncture function, and increasing the lightning protection and grounding function. The number of puncture points 111a can be 1, or multiple, such as 2, 3, 4 or more. Exemplarily, as Figure 1 shown, 4 puncture points are provided on the upper limit plate 111, forming a rectangular array, located at the middle position of the upper limit plate 111. Further, the shape of the puncture point 111a is circular, realized by a stamping die. Circular stamping is more convenient, and the puncture point is sharper, which can better achieve the puncture effect.

[0036] The bottom plate 112 is connected to the second component 120, and both of them can be on the same side (the lower side in the figure) of the upper limit plate 111. When the first component 110 is connected to the second component 120, the 4 puncture points on the upper limit plate 111 do not exceed the range defined by the two side walls 122 of the second component 120, so as to align with the top plate 121 of the second component 120, so that it can be clamped more firmly.

[0037] The bottom plate 112 has opposite first side (the left side in the figure) and second side (the right side in the figure). In some embodiments, the first side of the bottom plate 112 is connected to the first side of the upper limit plate 111, and the second side of the bottom plate 112 is connected to the second component 120.

[0038] Optionally, the projection of the upper limit plate 111 on the plane where the upper surface of the second component 120 is located at least covers part of the upper surface of the second component. This embodiment can enhance the force-bearing of the fixing device 100 and improve the stability of the connection. It should be understood that in some other embodiments, the upper limit plate 111 and the second component 120 can also be connected to the same side of the bottom plate 112, and the projection of the upper limit plate 111 on the plane where the upper surface of the second component 120 is located can also completely not cover the upper surface of the second component. The present invention does not limit this.

[0039] Further, the lengths of the upper limit plate 111 and the bottom plate 112 in the first direction (roughly the front-back direction in the figure) are the same, and the length of the upper limit plate 111 in the first direction is greater than the length of the second component 120 in the first direction, where the first direction is the direction in which the photovoltaic module frame 200 is inserted into the limit groove 113, such as Figure 1 shown by the arrow direction. This embodiment increases the force-bearing area between the frame and the target component, strengthens the load capacity of the photovoltaic module, and can improve the problem of fracture and tearing of the photovoltaic module.

[0040] In some embodiments, the first component 110 may further include a clamping plate 114, which is connected to the second side of the upper limiting plate 111. The clamping plate 114 is located on the side of the upper limiting plate 111 away from the second component 120 (the upper side in the figure). In these embodiments, the clamping plate 114 may be in contact with a side plate 202 of the photovoltaic module frame 200 (refer to Figure 4 , also known as the D surface), to achieve effective limiting. Further, the clamping plate 114 is an arc-shaped clamping plate, which facilitates the insertion of the support bottom plate 201 of the photovoltaic module frame 200. It should be understood that the clamping plate 114 may also be of other shapes, and the present invention does not limit this.

[0041] Continuing to refer to Figures 1-3 , the second component 120 of the fixing device 100 includes two side walls 122 for clamping into a target member (such as Figure 4 C-shaped steel 300 or Figure 7 color steel tile 400), which can achieve snap-in embedding without screw installation, improving the installation efficiency. Preferably, one or more elastic limiting claws 123 are provided on the side walls 122, and the limiting claws 123 protrude outwards. Barbs 124 may also be provided at the edges of the side walls 122, which can hold the target member, improving the stability of the connection between the fixing device and the target member.

[0042] It should be noted that the fixing device 100 in the embodiments of the present invention may be an integral component or an assembled component, that is, the first component 110 and the second component 120 of the fixing device 100 are not separable, or can be separated, and the present invention does not limit this.

[0043] In the embodiments of the present invention, the material of the fixing device 100 may be spring steel, etc., which has high elasticity, high toughness, good fatigue resistance and wear resistance, enhancing the durability of the fixing device.

[0044] Please refer to Figures 4-6 , the photovoltaic module frame 200 can be fixedly connected to the C-shaped steel 300 through the fixing device 100. The C-shaped steel 300 has an opening 301 and mounting plates 302 located on both sides of the opening. The second component 120 of the fixing device 100 enters the opening 301, and its two side walls 122 are pressed inwards and are in close contact with the mounting plates 302 on both sides of the opening, and the barbs 124 hold the mounting plates 302. In this way, the fixing device 100 is firmly installed on the C-shaped steel 300.

[0045] Please refer to Figures 7-8 , the photovoltaic module frame 200 can be fixedly connected to the color steel tile 400 through the fixing device 100. The top of the color steel tile 400 is a support surface 401, and it has a groove 402. The size of the groove 402 changes suddenly from the bottom to the mouth 403, forming a clamping point 404.

[0046] The side wall 122 of the second component 120 of the fixing device 100 is placed along the opening 403 of the groove 402 of the color steel tile 400. The limiting claw 123 is closely attached to the side wall of the opening 403, and the barb 124 is snapped into the clamping point 404 of the color steel tile 400. The first component 110 of the fixing device 100 is placed on the supporting surface 401 of the color steel tile 400.
