Detailed Description

Known from the background art, the problem that glue overflow occurs when the photovoltaic module is clamped by the photovoltaic module frame exists at present.

Analysis finds that one of the reasons for the glue overflow is that when the sealant is filled between the accommodating groove and the contact surface of the photovoltaic module, in order to ensure the bonding effect between the photovoltaic module and the surface of the accommodating groove, an excessive filling problem may occur, and therefore, the excessive sealant will overflow to the surface of the photovoltaic module, so that the glue overflow phenomenon occurs.

The utility model provides a photovoltaic module frame, include: a main body portion including: the first limiting part, the second limiting part and the top bearing part are sequentially combined to form an accommodating groove in a surrounding mode, the first limiting part is opposite to the top bearing part, and the surface, facing the accommodating groove, of the first limiting part is provided with at least one protruding part; the main body further includes: the side edge part, the bottom bearing part and the extension part are sequentially connected with each other to surround the forming cavity, and the side edge part is connected with the top bearing part. At least one protruding part is arranged on the surface of the first limiting part facing the accommodating groove, so that the surface of the first limiting part facing the glue accommodating groove is provided with a concave-convex structure, when the photovoltaic assembly is clamped into the accommodating groove, a cavity can be formed between the surface of the first limiting part facing the top bearing part and the surface of the photovoltaic assembly, the cavity can serve as the glue accommodating groove and is used for storing redundant sealant, and the glue overflowing phenomenon can be improved.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the invention. However, the claimed invention can be practiced without these specific details and with various changes and modifications based on the following examples.

Referring to fig. 1, fig. 1 is a schematic view of a cross-sectional structure of a photovoltaic module frame provided by the present invention, the photovoltaic module frame includes: a main body portion including: the first limiting part 101, the second limiting part 102 and the top bearing part 103 are sequentially connected to form the accommodating groove 20 in a surrounding mode, the first limiting part 101 is opposite to the top bearing part 103, and the surface, facing the accommodating groove 20, of the first limiting part 101 is provided with at least one protruding part; the main body further includes: the side edge part 104, the bottom bearing part 105 and the extension part 106 are sequentially connected to form the cavity 30, and the side edge part 104 is connected with the top bearing part 103.

At least one protruding part is arranged on the surface of the first limiting part 101 facing the accommodating groove 20, so that the surface of the first limiting part 101 facing the accommodating groove is provided with a concave-convex structure, and thus when the photovoltaic module is clamped into the accommodating groove 20, a cavity can be formed between the concave-convex structure of the first limiting part 101 facing the top bearing part 103 and the surface of the photovoltaic module, and the cavity can serve as the accommodating groove for storing redundant sealant, so that the sealant overflow phenomenon can be improved.

The accommodating groove 20 is used for clamping the photovoltaic module to accommodate the photovoltaic module. The cavity 30 is configured to receive an external mating structure to secure the photovoltaic module frame. When the photovoltaic module is clamped, the first limiting portion 101 contacts with one surface of the photovoltaic module, the second limiting portion 102 contacts with a side edge of the photovoltaic module, so that the position where the photovoltaic module enters the accommodating groove 20 is limited, and the bearing portion contacts with the other surface of the photovoltaic module to bear the photovoltaic module.

In some embodiments, the height of the raised portion is no greater than 3mm in a direction along the first stop portion 101 toward the top carrier portion 103. When the photovoltaic module is clamped into the photovoltaic module frame, the surface of the protruding portion is abutted against the surface of the photovoltaic module, on one hand, a cavity can be formed to serve as a glue containing groove, redundant sealant is stored, the glue overflowing phenomenon can be improved, and the sealant storage capacity can be improved to improve the bonding strength. On the other hand, the surface of the first limiting portion 101 facing the glue containing groove is of a concave-convex structure, so that an anti-slip effect can be achieved, and the bonding strength of the glue containing groove 20 to the photovoltaic module is further improved. Set up the height of bellying and be not more than 3mm, on the one hand, in this within range, when the surface of bellying and photovoltaic module surface butt, the cavity that forms between the concave-convex structure of first spacing portion 101 orientation top bearing part 103 and the photovoltaic module surface is great, can hold more sealed glue. On the other hand, in this range, the height of the protruding portion is not too large, because when the height of the protruding portion is too large, the height of the second limiting portion 102 needs to be set high to accommodate the photovoltaic module. Therefore, the height of the protruding portion is not greater than 3mm, the material for forming the second limiting portion 102 can be saved, and the cost for preparing the photovoltaic module frame is low.

Referring to fig. 2, fig. 2 is a schematic top view of a partial structure of a photovoltaic module frame provided in the present invention, in some embodiments, the protruding portion 15 may extend along an extending direction of the length of the first limiting portion 101, that is, the projection shape of the protruding portion 15 on the surface of the first limiting portion 101 is a bar shape, so that the process for preparing the protruding portion 15 is simpler.

Referring to fig. 3 and fig. 4, fig. 3 is a schematic view of a cross-sectional structure of another photovoltaic module frame provided by the present invention, fig. 4 is a schematic view of a partial structure of another photovoltaic module frame provided by the present invention, in some embodiments, the number of the protrusions 15 is at least 2, and the arrangement direction of at least part of the protrusions 15 is the same as the length extension direction of the top bearing part 103, that is, the protrusions 15 are arranged on the surface of the first limiting part 101 at intervals, so the number of the protrusions 15 is more, so that the concave-convex structure of the surface of the first limiting part 101 facing the bearing part is more dense, when the photovoltaic module is engaged into the accommodating groove 20, more glue accommodating grooves can be formed between the surface of the first limiting part 101 facing the top bearing part 103 and the photovoltaic module, thereby further improving the glue overflow phenomenon.

In some embodiments, the number of the protrusions is at least 2, and the heights of the adjacent protrusions in the direction perpendicular to the surface of the bearing part increase in the direction toward the receiving groove 20. Thus, when the photovoltaic module is clamped into the photovoltaic module frame, the protruding portion with the largest height is in contact with the surface of the photovoltaic module, namely, the protruding portion far away from the second limiting portion 102 is in contact with the surface of the photovoltaic module, and the protruding portion with the relatively smaller height is not in contact with the surface of the photovoltaic module, so that a cavity can be formed between the protruding portion which is not in contact with the surface of the photovoltaic module and the surface of the photovoltaic module. Therefore, compared with the case that the heights of the adjacent protruding portions in the direction perpendicular to the surface of the carrying portion are the same, the heights of the adjacent protruding portions in the direction perpendicular to the surface of the carrying portion are sequentially increased, so that a cavity formed between the first limiting portion 101 and the photovoltaic module is larger, more sealant can be contained, and the phenomenon of sealant overflow is further improved. Referring to fig. 2 and 4, in some embodiments, when the heights of the adjacent protrusions 15 in the direction perpendicular to the surface of the carrying portion are sequentially increased, the projection sizes of the protrusions 15 in the direction parallel to the surface of the first position-limiting portion in the direction toward the receiving groove 20 are also sequentially increased. In other embodiments, the projection dimension of the protrusion 15 in the direction toward the receiving groove 20 may be the same in the direction parallel to the surface of the first position-limiting portion.

It will be appreciated that in other embodiments, the height of adjacent projections in a direction perpendicular to the surface of the carrier may be the same in a direction toward receiving slot 20.

In some embodiments, the spacing between adjacent lobes is no greater than 6 mm. In this scope for the concave-convex structure that first spacing portion 101 formed towards the surface of top bearing part 103 has great unsmooth degree, thereby makes the accommodation space of the cavity that forms between first spacing portion 101 surface and the photovoltaic module great, can hold more sealed glue, can improve overflow gluey phenomenon on the one hand, and on the other hand can also promote sealed glue reserves in order to promote adhesion strength.

Specifically, in some embodiments, the protruding portion may be located at an end of the first position-limiting portion 101 away from the second position-limiting portion 102, so that a cavity formed between the protruding portion, the photovoltaic module and a side of the second position-limiting portion 102 is larger, and thus more sealant can be accommodated, and the phenomenon of sealant overflow is further improved. In addition, the surface of first spacing portion 101 towards top bearing portion 103 is concave-convex structure, still makes the surface of first spacing portion 101 towards top bearing portion 103 have anti-skidding effect, so, makes the holding glue groove more stable to photovoltaic module's block, thereby makes the holding glue groove have better fixed effect.

Specifically, in some embodiments, in a cross section perpendicular to a direction in which the length of the first stopper portion 101 extends, the shape of the protruding portion may be at least one of a semicircular shape, a trapezoidal shape, or a rectangular shape. When the shape of the protruding portion is semicircular, the concave-convex structure formed on the surface of the first limiting portion 101 facing the top bearing portion 103 is smooth, and therefore when the photovoltaic module is clamped into the accommodating groove 20, the problem of scratching the surface of the photovoltaic module can be prevented. It can be understood that, in some embodiments, the surface of the first position-limiting portion 101 away from the receiving groove 20 corresponding to the protrusion may protrude toward the receiving groove 20, and in other embodiments, the surface of the first position-limiting portion 101 away from the receiving groove 20 corresponding to the protrusion may also be a plane, so long as the surface of the first position-limiting portion 101 toward the receiving groove 20 has the protrusion toward the receiving groove 20.

Referring to fig. 5, fig. 5 is a schematic view of a cross-sectional structure of a photovoltaic module frame according to another embodiment of the present invention, in some embodiments, the first limiting portion may further include a first protruding portion protruding toward the direction away from the receiving groove, and the first protruding portion may be located on one side of the protruding portion toward the second limiting portion, so that when the photovoltaic module is clamped into the receiving groove, a cavity may be formed between the first protruding portion and the surface of the photovoltaic module, and more sealant may be received.

Referring to fig. 6, fig. 6 is a schematic cross-sectional structure diagram of another photovoltaic module frame provided by the present invention, in some embodiments, the main body portion may further include: and a protection part 108, wherein the protection part 108 is connected with the end part of the extension part 106, and the protection part 108 is bent relative to the extension part 106. The extension part 106 is connected with the bottom bearing part 105 at the bottom of the cavity 30, so that on one hand, the effect of improving the frame strength of the photovoltaic module is achieved, and on the other hand, the stability of installation is improved when the cavity 30 is installed. Since the end of the extending portion 106 away from the bottom bearing portion 105 has a notch, and the notch faces the top bearing portion 103 vertically, i.e. the notch faces upward horizontally, moisture and dust are likely to accumulate at the notch of the extending portion 106, which may corrode the frame of the photovoltaic device in the past, thereby reducing the service life of the frame of the device. Therefore, the protection portion 108 is disposed to contact the end of the extension portion 106, so that the cut at the end of the extension portion 106 can be protected from being exposed. And protection part 108 is bent for extending, that is to say, the tip of protection part 108 bends to the relative both sides of extension 106, so, make the relative extension 106 slope of incision of protection part 108 tip set up, consequently, moisture and dust are difficult to pile up on the incision surface of protection part 108 tip, can effectively improve moisture and dust and produce the problem of corruption to the photovoltaic module frame, and then prolong the life of photovoltaic module frame.

In some embodiments, the material of the photovoltaic module bezel may be a steel material, for example, any of stainless steel, alloy steel, cast steel. The steel material has high strength and hardness, and good temperature resistance and processability. Compare in the aluminium material that present photovoltaic module frame used, use the steel material to prepare the photovoltaic module frame, can promote the intensity of photovoltaic module frame on the one hand, on the other hand, the cost of steel material is lower, consequently can reduce the cost of photovoltaic module frame.

In some embodiments, the first position-limiting portion 101 has a top position-limiting portion 11 and a first bent portion 10, the first bent portion 10 is bent toward a side of the first position-limiting portion 101 away from the top carrying surface 103, the top position-limiting portion 11 is opposite to the top carrying surface 103, and an included angle between a surface of the first bent portion 10 facing the top carrying surface 103 and a top surface of the top position-limiting portion 11 may be 0 ° to 90 °, for example, 0 °, 30 °, or 60 °. The top limit part 11 is opposite to the top bearing part 103, and plays a role in limiting the photovoltaic module. In this range, the end of the first position-limiting part 101 is a curved surface rather than a sharp prismatic side, so that when the photovoltaic module enters the accommodating groove 20, the problem that the end of the first position-limiting part 101 scratches the surface of the photovoltaic module due to too close contact between the accommodating groove 20 and the photovoltaic module can be prevented. In addition, in the angle range, the process for actually preparing the bent part is easy to realize, and the large-scale production is facilitated.

In some embodiments, further comprising: the transition portion 107, the transition portion 107 meets with the top bearing portion 103 and the side edge portion 104 respectively, the end portion of the transition portion 107 far away from the top bearing portion 103 faces the side of the top bearing portion 103 far away from the first limiting portion 101, and an included angle between a bottom surface of the transition portion 107 facing the cavity 30 and a bottom surface of the top bearing portion 103 facing the cavity 30 may be 90 ° to 180 °, for example, 120 °, 135 °, or 150 °. That is, the transition portion 107 is disposed obliquely to the side portion 104, so as to provide an overflow path for the sealant between the accommodating groove 20 and the photovoltaic module. That is, when the photovoltaic module is engaged into the receiving groove 20, the excess sealant between the top bearing portion 103 and the photovoltaic module can flow out along the surface of the transition portion 107 under the action of the gravity of the sealant itself, so that the sealant is not accumulated at the junction between the bearing portion and the photovoltaic module, and the photovoltaic module is kept more beautiful. In addition, because the transition portion 107 is disposed to the oblique side portion 104, the transition portion can also be used as a buffering structure of a frame of the photovoltaic module, so as to improve the bearing stability of the top bearing portion 103 in the accommodating groove 20.

In some embodiments, the width of the first stopper portion 101 may be greater than the width of the top carrier portion 103 in a direction extending perpendicular to the top carrier portion 103. That is, in the extending direction perpendicular to the top carrying portion 103, the width of the top carrying portion 103 is smaller, so that, on one hand, when the excessive sealant between the surface of the top carrying portion 103 and the surface of the photovoltaic module overflows, a shorter glue overflow path is provided, so that the sealant can flow out along the transition portion 107 more, thereby improving the glue overflow phenomenon. On the other hand, with the less of width design of top bearing part 103, not only can sparingly form the raw and other materials of photovoltaic module frame, still make the dead weight of photovoltaic module frame less to be favorable to photovoltaic module's transportation, and can also make the shock resistance of photovoltaic module frame better, thereby have better guard action to photovoltaic module.

In some embodiments, the side edge 104 may include: a first side edge portion 12, a second side edge portion 13, and a bead 14, the bead 14 being positioned between the first side edge portion 12 and the second side edge portion 13, and the bead 14 projecting toward a side of the side edge portion 104 away from the cavity 30. And reinforcing ribs 14 protruding towards the side far away from the cavity 30 are arranged at the middle positions of the side edge parts 104, so that the mechanical strength of the photovoltaic module frame is enhanced. Specifically, the reinforcing ribs 14 are arranged on the side edge portions 104, so that the effect of enhancing the mechanical strength of the photovoltaic module frame can be achieved under the condition that the thickness of the side edge portions 104 is not increased, the problem that the photovoltaic module frame is distorted and deformed due to the fact that the thickness of the side edge portions 104 is relatively thick can be prevented, and meanwhile materials can be saved. In addition, the reinforcing ribs 14 are arranged, so that the mechanical strength of the photovoltaic module frame is enhanced, the self weight of the photovoltaic module frame is smaller, and the photovoltaic module frame has a better shockproof effect. It is understood that in other embodiments, a plurality of ribs 14 may be disposed at intervals on the side edge portion 104 to further enhance the mechanical strength of the photovoltaic module frame. In still other embodiments, the ribs 14 may also project toward the side of the cavity 30 toward the side edge 104.

In some embodiments, the photovoltaic module frame may be further subjected to plating treatment, for example, the photovoltaic module frame may be plated with nickel or plastic, so that the photovoltaic module frame has better corrosion resistance and the service life of the photovoltaic module frame is prolonged.

The utility model provides an among the photovoltaic module frame, the photovoltaic module frame includes: a main body portion including: the photovoltaic module accommodating device comprises a first limiting part 101, a second limiting part 102 and a top bearing part 103, wherein the first limiting part 101, the second limiting part 102 and the top bearing part 103 are sequentially connected and encircled to form an accommodating groove 20, the accommodating groove 20 is used for clamping a photovoltaic module to accommodate the photovoltaic module, the first limiting part 101 is opposite to the top bearing part 103, and the surface of the first limiting part 101 facing the accommodating groove 20 is provided with at least one protruding part; the main body further includes: the photovoltaic module comprises a side edge part 104, a bottom bearing part 105 and an extension part 106, wherein the side edge part 104, the bottom bearing part 105 and the extension part 106 are sequentially connected to form a cavity 30, the side edge part 104 is connected with the top bearing part 103, and the cavity 30 is used for fixing the photovoltaic module.
