After the photovoltaic module frame is assembled with the guide rail 1, the two ends of the second frame body 22 are overlapped on the guide rail 1, so that the photovoltaic frame is further supported.

To further improve the supporting effect of the guide rail 1 on the photovoltaic frame, the structure of the second frame 22 may be the same as that of the body of the first frame 21.

In another embodiment, the second sliding portion 20 may be provided at the bottom of the second frame 22, and it should be noted that, in the second sliding portion 20 of the second frame 22, the first vertical plate 216 is perpendicular to the longitudinal direction of the second frame 22, so that the second sliding portion 20 of the second frame 22 can be slidably engaged with the first sliding portion 10 on the guide rail 1 along the longitudinal direction of the first frame 21, and the fixing effect of the guide rail 1 and the photovoltaic module frame is further improved.

When the guide rail 1 is assembled with the frame 2, the second sliding portion 20 extends into the first sliding groove 16 on the first sliding portion 10, and the top plate 101 and the folded edge 103 extend into the second sliding groove 219 on the second sliding portion 20, so that the guide rail 1 and the frame 2 are nested and slide, and the sliding fit effect of the guide rail 1 and the frame 2 can be further improved.

Alternatively, two first frame bodies 21 may be slidably fitted on the same guide rail 1, and the two first frame bodies 21 are arranged in a mirror image manner with respect to the length direction of the guide rail 1. Two first frame bodies 21 are supported through one guide rail 1, the number of the guide rails 1 required for fixing a plurality of photovoltaic modules can be reduced, and cost reduction is facilitated.

In order to improve the accuracy of the mounting position of the first frame 21 on the guide rail 1, as shown in fig. 5, in the present embodiment, the end of the guide rail 1 in the longitudinal direction thereof may be further provided with an elastic protrusion 13. When the first frame 21 is slidably installed on the guide rail 1, the first frame 21 can press the elastic protrusion 13, so that the elastic protrusion 13 is compressed, and the first frame 21 can smoothly slide into the guide rail 1. When the first frame body 21 is installed in place, the elastic protrusions 13 are released to bounce, and the elastic protrusions 13 cooperate with the first frame body 21 to limit the position of the first frame body 21, so that the first frame body 21 is fixed.

In this embodiment, in order to improve the matching and positioning effect between the elastic protrusion 13 and the first frame 21, a clamping groove is further disposed on the frame 2. After the first frame body 21 slides in place, the elastic protrusions 13 correspond to the clamping grooves in position, the elastic protrusions 13 are not stressed any more, so that the elastic protrusions 13 are bounced and released, the elastic protrusions 13 are clamped into the clamping grooves, the first frame body 21 is limited to continue sliding along the length direction of the guide rail 1, and the purpose of positioning is achieved. Alternatively, the card slot may be provided at the bottom of the first frame 21, or may be provided at the bottom of the second frame 22.

In other embodiments, the elastic protrusion 13 may also be disposed at the bottom of the first frame 21 or the second frame 22, and the corresponding slot is disposed at the top of the guide rail 1, so that the elastic protrusion 13 and the slot can also be engaged with each other.

Optionally, the elastic protrusion 13 may be matched with the end of the frame 2 after being released and bounced, and the sliding of the frame 2 is limited by abutting the end of the frame 2 departing from the sliding-in mounting direction. Under this kind of circumstances, in order to avoid frame 2 to continue to slide along the installation direction that slides in, a plurality of frames 2 can be installed along its length direction on same guide rail 1, and adjacent frame 2 butt to realize frame 2 along the spacing of guide rail 1's length direction both sides.

With continued reference to fig. 5 and 6, the guide rail 1 is provided with a positioning hole 11, and the elastic protrusion 13 can protrude out of the positioning hole 11 when no external force is applied, so as to be clamped into the clamping groove.

When the first frame 21 is slidably installed on the guide rail 1, the bottom surface of the first frame 21 gradually presses the elastic protrusion 13 under the guiding action of the inclined surface, so that the elastic protrusion 13 is compressed into the positioning hole 11, and the normal installation of the first frame 21 is ensured. When the first frame 21 is mounted in place, the elastic protrusion 13 is no longer stressed and automatically bounces, so as to be clamped into the clamping groove at the bottom of the first frame 21.
