In practice, in order to achieve a better packaging effect, after the side edge of the laminated piece 1 is installed in the photovoltaic frame 2, packaging glue is filled between the side edge of the laminated piece 1 and the photovoltaic frame 2, and after the packaging glue is cured, packaging of the photovoltaic module can be achieved.

Further, to enhance the encapsulation effect, a portion of the top wall of the photovoltaic frame 2, which is to be received by the encapsulation compound, is recessed upward to form a compound groove 22 (as shown in fig. 3). On the one hand, the glue groove 22 can contain more packaging glue, so that the packaging effect is improved; on the other hand, the glue groove 22 can also prevent the overflow phenomenon of the packaging glue before curing.

After the photovoltaic module is packaged, the photovoltaic frame 2 can be fixedly mounted on the outdoor mounting bracket 4, and then the photovoltaic module can be normally used outdoors.

To ensure that the packaged photovoltaic module is fixedly mounted to the outdoor mounting bracket 4, the photovoltaic module further includes a fixing module 3 (shown in fig. 2) for fixedly mounting the photovoltaic frame 2 to the outdoor.

Further, referring to fig. 3, the bottom of the photovoltaic frame 2 is provided with an outwardly extending mounting portion 21, and the mounting portion 21 is provided with first mounting holes 211 penetrating the upper and lower surfaces thereof. The mounting bracket 4 is provided with a second mounting hole 41 penetrating the upper and lower surfaces thereof.

The fixing component 3 is an anti-tearing fixing component for a photovoltaic component according to the embodiment. The fixing component 3 can be applied to the photovoltaic frames 2 made of various materials such as aluminum frames, steel frames or composite frames.

Referring to fig. 4-5, a tearing-proof fixing assembly for a photovoltaic module of this embodiment includes an upper collar 31 (shown in fig. 5), a lower collar 32 and a fastener 34 (shown in fig. 4).

In this embodiment, the upper collar 31 and the lower collar 32 are made of metal materials with good mechanical strength and rust resistance. Preferably, the upper collar 31 and the lower collar 32 are made of carbon steel, stainless steel or aluminum alloy; the thickness of these materials used for the upper collar 31 and the lower collar 32 includes, but is not limited to, 0.1-2mm, such as 0.1mm, 0.3mm, 0.5mm, 0.9mm, 1.2mm, 1.5mm, 1.8 or 2mm.

Referring to fig. 4-5, the upper collar 31 includes a mounting tab 311 and a sleeve 312 coupled to the underside of the mounting tab 311. The mounting piece 311 is attached to the upper surface of the first mounting hole 211 to strengthen and fix the upper surface of the first mounting hole 211; the sleeve 312 is sequentially sleeved on the inner peripheral wall of the first mounting hole 211 and the inner peripheral wall of the second mounting hole 41, so as to strengthen and fix the inner peripheral walls of the first mounting hole 211 (shown in fig. 3) and the second mounting hole 41 (shown in fig. 3). Further, the mounting piece 311 and the sleeve 312 are provided with through holes 36 (as shown in fig. 5) at positions corresponding to the first mounting holes 211 for mounting the fasteners 34.

In practice, the mounting piece 311 and the sleeve 312 are preferably integrally formed, so as to simplify the structure of the upper collar 31 and thus simplify the mounting process. The upper collar 31 is preferably formed by one-shot stamping, that is, the mounting piece 311 and the sleeve 312 are formed by one-shot stamping, so as to reduce the production process and the production cost of the upper collar 31.

The sleeve 312 is preferably perpendicularly attached to the lower surface of the mounting plate 311. The entire upper collar 31 is inverted "t" shaped when viewed from the side.

Referring to fig. 4 to 5, the lower collar 32 is attached to the lower surface of the second mounting hole 41 to strengthen the fixing of the mounting bracket 4 and the second mounting hole 41. Further, the lower collar 32 is provided with through holes 36 (shown in fig. 5) penetrating the upper and lower surfaces thereof at positions corresponding to the second mounting holes 41 for mounting the fasteners 34. The lower collar 32 is shaped in a "straight" from the side.

Therefore, by the fitting of the mounting piece 311, the sleeve 312 and the lower collar 32, the surface and the inner peripheral wall of the first mounting hole 211, the inner peripheral wall of the second mounting hole 41 and the lower surface of the second mounting hole 41 of the mounting portion 21 can be well reinforced and fixed, so that the fatigue failure problem, deformation and tearing risk caused by the stress concentration of the materials of the parts of the first mounting hole 211 and the second mounting hole 41, which are in contact with the fastener 34, under long-term stress can be prevented.

Wherein, the lower end of the sleeve 312 is detachably mounted on the lower collar 32, so as to facilitate the mounting and dismounting of the upper collar 31 and the lower collar 32.

The lower end of sleeve 312 is preferably nestably mounted to lower collar 32 to achieve a sufficient fit between the various fastening mounting structures.

Specifically, the equivalent diameter of the through hole 36 of the lower collar 32 is larger than that of the sleeve 312, so that the lower end portion of the sleeve 312 is fitted into the inner peripheral wall of the through hole 36 of the lower collar 32 after passing through the inner peripheral wall of the first mounting hole 211 and the inner peripheral wall of the second mounting hole 41 in this order.

Further, the buffer layer 33 is provided on each of the mounting surfaces (or contact surfaces) of the mounting piece 311, the sleeve 312, and the lower collar 32 with the first mounting hole 211 and the second mounting hole 41 (the buffer layer 33 is shown as a filling portion in fig. 5). Specifically, the buffer layer 33 is disposed on the lower surface of the mounting plate 311, the outer peripheral wall of the sleeve 312, and the upper surface of the lower collar 32, so as to better protect the structure of the mounting contact surface and prevent structural damage between the frame and the mounting.

In practice, the buffer layer 33 may be provided on the lower surface of the mounting piece 311, the outer peripheral wall of the sleeve 312, and the upper surface of the lower collar 32 in advance by bonding or other connection means. In one example of the present embodiment, the buffer layer 33 is fixedly attached to the lower surface of the mounting piece 311, the outer peripheral wall of the sleeve 312, and the upper surface of the lower collar 32. In another example of the present embodiment, the buffer layer 33, the upper collar 31 and the lower collar 32 may be configured independently from each other, and the buffer layer 33 is attached to the corresponding mounting contact surfaces of the upper collar 31 and the lower collar 32 in advance before the fixing assembly 3 is mounted.

Unlike the outer peripheral wall of the bolt having a screw structure protruding outward, the outer peripheral wall of the sleeve 312 is a smooth surface provided with the buffer layer 33, so that the outer peripheral wall of the sleeve 312 is more tightly bonded to the inner peripheral walls of the first mounting hole 211 and the second mounting hole 41, and the area of bonding (or contact) can be increased; the outer peripheral wall of the sleeve 312 does not have a thread structure protruding outwards, and the inner peripheral walls of the first mounting hole 211 and the second mounting hole 41 are not scratched or damaged; the sleeve 312 can well reinforce and protect the inner peripheral walls of the first mounting hole 211 and the second mounting hole 41. Moreover, after the outer peripheral wall of the sleeve 312 is tightly attached to the inner peripheral walls of the first mounting hole 211 and the second mounting hole 41, the photovoltaic frame 2 and the mounting bracket 4 can be well bound together through the sleeve 312, so that the collision, extrusion and damage of the screw thread structure of the outer peripheral wall of the bolt to the inner peripheral wall of the first mounting hole 211 or the inner peripheral wall of the second mounting hole 41 caused by shaking of the mounting bracket 4 or the photovoltaic frame 2 in the outdoor use process can be avoided.

In the fixing assembly 3 of the present embodiment, the mounting piece 311, the sleeve 312 and the lower collar 32 can play a good role in reinforcing and fixing the mounting contact surfaces of the first mounting hole 211 and the second mounting hole 41, so as to prevent the fatigue failure problem, deformation and tearing risk caused by the materials of the first mounting hole 211 and the second mounting hole 41; in addition, the buffer layer 33 can also play a good role in buffering and protecting the structure of the mounting contact surface, so as to prevent the mounting structure from being damaged; furthermore, through the mutually supporting of mounting piece 311, sleeve 312, lower lantern ring 32 and buffer layer 33, can strengthen the reliability of the fastening installation of photovoltaic frame 2 on outdoor installing support 4, promote photovoltaic frame 2 and photovoltaic module's anti load ability outdoor, satisfy the load requirement that photovoltaic module used for a long time under abominable outdoor environment.

In this embodiment, the overall shape of the upper collar 31 and the lower collar 32, and the shape of the mounting piece 311, the sleeve 312, and the through hole 36 of the lower collar 32 can be adjusted accordingly according to the actual mounting contact surface.

In practice, the material of the buffer layer 33 includes, but is not limited to, natural rubber, EPDM (ethylene propylene diene monomer) or nylon, so as to perform better buffering and protection functions.

Still further, a spring pad 35 is provided between the lower collar 32 and the nut 342 to increase contact friction and thereby prevent loosening of the installed fastener 34 during long term use.

The fastener 34 may be a threaded fastener or other existing fastener. The fastener 34 is preferably a threaded fastener that includes a threaded bolt 341 and a nut 342.

In practice, the height of the sleeve 312 is smaller than the sum of the thicknesses of the first mounting hole 211, the second mounting hole 41, the lower collar 32 and the spring pad 35, or the height of the sleeve 312 is equal to the sum of the thicknesses of the first mounting hole 211, the second mounting hole 41, the lower collar 32 and the spring pad 35 to ensure the fastening effect.

When the fixing assembly 3 is installed, referring to fig. 2-5, the sleeve 312 is first installed into the first installation hole 211 and the second installation hole 41, the outer peripheral wall of the sleeve 312 is attached to the inner peripheral wall of the first installation hole 211 and the inner peripheral wall of the second installation hole 41, and the lower surface of the installation piece 311 is attached to the upper surface of the first installation hole 211, at this time, the installation piece 311 and the through hole 36 of the sleeve 312 vertically correspond to the first installation hole 211; then, the upper surface of the lower collar 32 is attached to the lower surface of the second mounting hole 41, and the through hole 36 of the lower collar 32 corresponds to the first mounting hole 211 and the second mounting hole 41 up and down; the lower end of the sleeve 312 is then nested within the through-hole 36 of the lower collar 32. In this way, the upper collar 31 and the lower collar 32 are mounted so as to reinforce the respective mounting contact surfaces of the first mounting hole 211 and the second mounting hole 41. Then, the lower end of the bolt 341 sequentially passes through the mounting plate 311, the sleeve 312, the lower collar 32, the spring pad 35 and the nut 342, and then is in threaded connection with the nut 342, so as to complete the fixed mounting of the mounting portion 21 of the photovoltaic frame 2 on the mounting bracket 4, and further realize the outdoor mounting and use of the photovoltaic module.
