Detailed Description

The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.

As shown in fig. 2, the utility model provides a photovoltaic module frame, which comprises a frame member 1, wherein the frame member 1 is in an L shape, and a photovoltaic panel 6 is arranged in the frame member 1; the support piece 2, the support piece 2 is connected to the lower surface of the frame piece 1, the support piece 2 includes a first support bar 21, a second support bar 22 and a connecting rod 23, one end of the first support bar 21 is connected to the middle of the lateral portion of the frame piece 1, one end of the second support bar 22 is connected to one end of the lateral portion of the frame piece 1, which is close to the photovoltaic panel 6, the connecting rod 23 is parallel to the lateral portion of the frame piece 1, the other ends of the first support bar 21 and the second support bar 22 are respectively connected to the middle and one end of the connecting rod 23, and a guide slot 9 is formed between one end of the lateral portion of the frame piece 1, which is far from the photovoltaic panel 6, and the other end of the connecting rod 23; the glue overflow preventing structure 3 comprises a glue overflow preventing piece 31, wherein the glue overflow preventing piece 31 is obliquely arranged on the inner surface of the longitudinal part of the frame piece 1; and the sealing silica gel 4 is filled at the position where the frame piece 1 is contacted with the photovoltaic panel 6.

Wherein, the junction of the transverse part and the longitudinal part of the frame member 1 forms a notch, when the sealing silica gel 4 is filled at the contact position of the frame member 1 and the photovoltaic panel 6, the sealing silica gel 4 is injected into the notch, then the photovoltaic panel 6 is placed on the inner surface of the frame member 1, and is pressed against the inner surface of the frame member 1 to obtain the sealing silica gel 4 as shown in fig. 2. During extrusion, the sealing silica gel 4 extends along the transverse part and the longitudinal part of the frame member 1 in a direction away from the notch due to the extrusion force of the photovoltaic panel 6 on the inner surface of the frame member 1, and the anti-overflow adhesive member 31 is obliquely downwards arranged on the inner surface of the longitudinal part of the frame member 1 and can be used for blocking a part of the sealing silica gel 4 from extending towards the longitudinal part of the frame member 1, so that the force applied to the sealing silica gel 4 when extending towards the longitudinal part of the frame member 1 is reduced, and the sealing silica gel 4 can be prevented from overflowing outwards to the upper surface of the photovoltaic panel 6.

Optionally, as shown in fig. 3, the frame member 1 further includes a first protrusion 11 and a second protrusion 12, where the first protrusion 11 is connected to the other end of the lateral portion of the frame member 1, and the second protrusion 12 is connected to the other end of the connecting rod 23.

In particular, the first projection 11 and the second projection 12 cooperate with the longitudinal portion of the frame member 1 and the connecting rod 23 to form a channel 9, the slot of the channel 9 facing away from the photovoltaic panel 6. The guide groove 9 with the structure can play a better fastening role on the sliding block 8 or the guide rail when being matched with the sliding block 8 or the guide rail for installation.

Optionally, the top end of the longitudinal portion of the frame member 1 is arc-shaped. By the arrangement, the damage to workers during installation due to the fact that the edge of the top end of the frame piece 1 is too sharp can be effectively avoided.

Wherein, the lower surface of the transverse part of the frame member 1 and the upper surface of the connecting rod 23 are oppositely provided with angle key clamping members 5. The corner key clamping piece 5 is used for installing the corner key when the photovoltaic panel 6 is packaged through the frame, so that the stability of the whole photovoltaic module structure is guaranteed.

Optionally, the glue overflow preventing structure 3 further includes a glue overflow groove 32, and the glue overflow groove 32 is disposed in the middle of the upper surface of the lateral portion of the frame member 1. The overflow groove 32 can increase the contact area between the sealing silica gel 4 and the frame member 1, and improve the mechanical property of the frame member 1.

Optionally, the frame member 1, the supporting member 2 and the glue overflow preventing structure 3 are integrally formed, so as to ensure that the whole photovoltaic module frame has good stability and good bearing property when the photovoltaic panel 6 is packaged.

When the photovoltaic panel 6 is packaged by the utility model, for the photovoltaic module which is vertically placed, the frame shown in fig. 2 or 3 can be selected for packaging on the upper side and/or the lower side (the side with the A-side frame which is easy to accumulate water and ash) of the photovoltaic panel 6, and the other two sides can be matched with the frame shown in fig. 4 or 5 (namely, the side with the A-side frame) for packaging. Of course, the other two sides can also be encapsulated by selecting the frame shown in fig. 2 or 3.

Specifically, for the frame shown in fig. 3, when the slider 8 is matched to encapsulate the photovoltaic panel 6, the shape of the slider 8 and the matching between the slider and the frame can be as shown in fig. 6, the slider 8 can slide on the guide groove 9, the upper surface of the slider 8 is provided with a first groove 81, which can be matched with the first protrusion 11, and the lower surface of the slider 8 is provided with a second groove 82, which can be matched with the second protrusion 12. The upper surface of the slide block 8 is provided with a first groove 81 on both sides, and the lower surface of the slide block 8 is provided with a second groove 82 on both sides, and the slide block 8 can slide on the guide groove 9 of the adjacent frame at the same time. The two first grooves 81 and the two second grooves 82 respectively formed on the upper surface and the lower surface of the sliding block 8 can connect the frame members 1 in two adjacent photovoltaic frame assemblies together, so that the stability of connection between the adjacent photovoltaic assembly frames and the stability of the whole photovoltaic assembly structure are ensured.

In addition, if the photovoltaic module frames are all frame members 1 without the first protrusions 11 and the second protrusions 12, the frame members 1 in two adjacent photovoltaic frame assemblies are connected by common bolts.

In summary, when packaging a photovoltaic panel 6, four frames are required, specifically, when packaging, one frame of the utility model can be used, and a plurality of frames with an A face 7 can be matched, and the frames of the utility model can also be used completely, but it should be noted that when the photovoltaic module is placed vertically, the frames of the utility model can achieve the effects of no water accumulation and no dust accumulation, and further, the working efficiency of the photovoltaic panel 6 is not affected.
