Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] like Figures 1 to 5 As shown, a photovoltaic panel pressing mechanism 10 of this embodiment includes a support foot 1 and a pressing block 2.

[0021] The bottom of the support foot 1 is used to connect and fix it to the photovoltaic track 20. The top of the support foot 1 has an inclined support plate 11. The support plate 11 is used to overlap the bottom edge of the inclined photovoltaic panel 30. A hook part 12 is provided above the end of the support plate 11 away from the photovoltaic panel 30.

[0022] The pressing block 2 includes a side plate 21, an upper plate 22, and an elastic locking part 23. The side plate 21 is vertically arranged, with the top of the side plate 21 connected to the upper plate 22 and the bottom of the side plate 21 connected to the elastic locking part 23. The upper plate 22 and the elastic locking part 23 are respectively arranged on opposite sides of the side plate 21. The elastic locking part 23 and the hook part 12 are elastically engaged, so that the upper plate 22, the side plate 21, and the support plate 11 form a locking area 3 that is open on the side and can lock the edge of the photovoltaic panel 30. When the pressing block mechanism 10 is provided on both sides of the photovoltaic panel 30, the support plate 11 supports the bottom surface of the edge of the photovoltaic panel 30, and the hook part 12 and the elastic locking part 23 of the pressing block mechanism 10 on both sides provide elastic force to press the side plate 21 and the upper plate 22 against the side end face and the top surface of the edge of the photovoltaic panel 30, respectively, so that both sides of the photovoltaic panel 30 can be locked and pressed tightly in the corresponding locking area 3.

[0023] Therefore, the photovoltaic panel 30 can be supported and fixed by simply using the pressure block 2 and the support foot 1 through a simple elastic snap-fit ​​connection, without the need for frequent tightening of screws and nuts, making construction convenient, efficient and efficient.

[0024] Specifically, in this embodiment, the support plate 11 is tilted at approximately 5° relative to the horizontal plane. In practice, this can be adjusted to meet the tilt angle requirements of the photovoltaic panel 30. The vertical length of the side plate 21 can be adjusted according to the thickness of the photovoltaic panel 30.

[0025] In this embodiment, the upper and lower ends of the side plate 21 are bent in opposite directions to the left and right to form an upper plate 22 and an elastic locking part 23. The upper plate 22 can be vertically connected to the side plate 21 to securely fasten it to the upper corner of the photovoltaic panel 30. The upper plate 22 is vertically connected to the side plate 21. The elastic locking part 23 includes an elastic part 231 and a spring piece 232 connected in sequence. The spring piece 232 is spaced apart from the side plate 21. One end of the elastic part 231 is connected to the lower end of the side plate 21, and the other end is connected to the lower part of the spring piece 232. The elastic part 231 can deform to provide elastic force. Specifically, the elastic part 231 can be U-shaped or V-shaped, etc. In this embodiment, the elastic part 231 is U-shaped to provide elastic deformation capability and ensure good structural strength.

[0026] The hook portion 12 may include a locking plate 121, the bottom of which is vertically connected to the end of the support plate 11 away from the photovoltaic panel 30. Specifically, it may be formed by bending and extending the support plate 11 upwards away from the photovoltaic panel 30. A locking block 122 may be protruded on the side of the locking plate 121 near the support plate 11. The other end of the elastic locking portion 23 away from the side plate 21, that is, the upper end of the spring piece portion 232, may be provided with a locking groove 233. The locking groove 233 can be locked and fixed with the locking block 122 of the hook portion 12 to ensure that the elastic locking portion 23 can maintain an elastic locking engagement with the hook portion 12. Of course, the locking block 122 may also be provided on the elastic locking portion 23 (not shown in the figure), and the locking groove 233 (not shown in the figure) may be provided on the hook portion 12, which can also achieve the locking engagement between the hook portion 12 and the elastic locking portion 23.

[0027] In this embodiment, the slot 233 can be formed within the protrusion 234 on the upper end of the spring piece portion 232 of the elastic snap-fit ​​portion 23, near the side of the snap plate 121. Simultaneously, a guide slope 235 is formed between the bottom of the protrusion 234 and the spring piece portion 232, near the snap-fit ​​block 122, to facilitate the downward snap-fit ​​of the elastic snap-fit ​​portion 23 between the snap-fit ​​hook portion 12 and the photovoltaic panel 30. The protrusion 234 improves the snap-fit ​​fixing effect.

[0028] In this embodiment, the support plate 11 extends forward and backward and is disposed on the left or right side of the top of the support foot 1. The pressure block 2 extends forward and backward, and the upper plate 22 and the elastic locking part 23 are respectively disposed on the left and right sides of the side plate 21. The front-to-back width of the support plate 11 can be greater than the front-to-back width of the pressure block 2. A through-hole 13 can be provided in the middle of the side of the support plate 11 near the hook part 12. The front-to-back width of the hole 13 is not less than the front-to-back width of the elastic locking part 23 of the pressure block 2, so that the lower part of the elastic locking part 23 can be accommodated in the hole 13, facilitating the elastic deformation of the elastic locking part 23. It also has a limiting function, which can prevent the pressure block 2 from moving forward and backward and disengaging from the support foot 1, and can ensure the reliability of the connection and fixation.

[0029] In this embodiment, the support plate 11 includes a support portion 111, an abutment portion 112, and a connecting portion 113 connected in sequence. The support portion 111 is close to and allows the photovoltaic panel 30 to be placed on top of it. The abutment portion 112 is bent upward relative to the support plate 11 and is inclinedly connected to the end of the support portion 111 away from the photovoltaic panel 30. The connecting portion 113 is parallel to the support plate 11 and is connected to the end of the abutment portion 112 away from the support portion 111. The other end of the connecting portion 113 is connected to the bottom of the hook portion 12. When the photovoltaic panel 30 is assembled, it can abut against the lower edge of the abutment portion 112 for positioning, which can improve the assembly accuracy and facilitate the clamping of the pressure block 2, thereby improving the assembly efficiency. Meanwhile, the abutment portion 112 and the connecting portion 113 on the side of the support plate 11 near the hook portion 12 can form a bent plate shape, which can improve the structural strength between the hook portion 12 and the support plate 11, and improve the snapping and fixing effect of the hook portion 12 on the elastic snapping portion 23 of the pressure block 2, thereby improving the fixing effect of the pressure block 2 on the photovoltaic panel 30.

[0030] The locking hole 13 can be provided on the abutment part 112 and the connecting part 113 to facilitate the resilient locking part 23 of the assembled pressure block 2.

[0031] In this embodiment, the support foot 1 includes a support plate 14, a lower connecting plate 15, and a support plate 11. The support plate 14 can be vertically arranged, and a horizontally extending lower connecting plate 15 can be provided on one side of the bottom of the support plate 14. The lower connecting plate 15 is provided with a connecting hole 151 for screws (not shown) to pass through, and can be used with conventional clips (not shown) to fix the support foot 1 to the photovoltaic track 20. The support plate 11 is provided on the other side of the top of the support plate 14 opposite to the lower connecting plate 15, and the top of the support plate 14 is connected to one end of the support portion 111 of the support plate 11.

[0032] The pressing mechanism 10 can work with the photovoltaic track 20 to form a photovoltaic bracket 40 that supports and fixes the photovoltaic panel 30.

[0033] Typically, a photovoltaic support 40 includes at least two photovoltaic tracks 20 spaced apart front to back. Each photovoltaic track 20 is provided with at least one pair of two pressure blocks 10 spaced apart left to right. Each pair of pressure blocks 10 on adjacent photovoltaic tracks 20 is front to back and back to each other. The support feet 1 of each pair of pressure blocks 10 spaced apart left to right are usually of different heights, and the support plates 11 of each pair of pressure blocks 10 spaced apart left to right are inclined at the same angle. Their respective snap-fit ​​areas 3 are arranged opposite each other to firmly support and fix the photovoltaic panel 30 in an inclined position, so as to facilitate the reception of sunlight.

[0034] By setting up the photovoltaic track 20 and the pressing mechanism 10, and assembling the photovoltaic panels 30, a photovoltaic system 50 can be formed, thereby realizing photovoltaic power generation and obtaining clean energy. The photovoltaic system 50 can be easily installed on rooftops, on water, on mountains, and other locations.
