As shown in fig. 1 to 4, the embodiment of the present utility model provides a cushion block 10, where the cushion block 10 is applied to a photovoltaic component and supports a suspended edge 201 of a photovoltaic module 20, and includes a first side 1 and a second side 2 that are oppositely arranged along a horizontal direction; the first side 1 is provided with a buffer space 3, and the buffer space 3 is recessed on the surface of the first side 1; the second side 2 is provided with a clamping space 4, the clamping space 4 is recessed in the surface of the second side 2, and the clamping space 4 is located above the buffer space 3. That is, a part of the photovoltaic module 20 (a part of the edge of the suspended edge 201) is located in the upper clamping space 4, the clamping space 4 can fix and support the photovoltaic module 20, and the deformation degree of the edge of the suspended edge 201 of the photovoltaic module 20 is reduced, so that the stress concentration of the contact position of the photovoltaic module 20 and the clamp is reduced, and the risk of damage such as hidden crack and the like generated by the photovoltaic module 20 is reduced; the buffer space 3 below can reduce the interaction force between the photovoltaic module 20 and the cushion block 10, and avoid stress concentration at the contact position of the photovoltaic module 20 and the cushion block 10; the opening directions of the clamping space 4 and the buffer space 3 are opposite, so that the deformation of the two sides of the cushion block 10 after being stressed is more uniform, and the cushion block 10 is prevented from being deformed obliquely to one side.

Wherein, the extending direction of the cushion block 10 is parallel to the length direction of the edge of the suspended edge 201, and the plane perpendicular to the extending direction of the cushion block 10 is the cross section of the cushion block 10, and the cross section shape of the cushion block 10 is described in the cross section of the cushion block 10 according to the embodiments of the present utility model.

Specifically, the cross section of the cushion block 10 is in an S-shaped structure as a whole, the first side 1 refers to a side located outside the photovoltaic module 20 in the cross section of the cushion block 10, and the second side 2 refers to a side located inside the photovoltaic module 20 in the cross section of the cushion block 10. The first side 1 is provided with a buffer space 3, the buffer space 3 is recessed on the surface of the first side 1, the second side 2 is provided with a clamping space 4, and the clamping space 4 is recessed on the surface of the second side 2, so that the first side 1 forms an upper-section closed lower-section open structure, and the second side 2 forms an upper-section open lower-section closed structure. The structure that the upper section of the first side 1 is closed to the opening of the lower section can not only form limit on the edge of the photovoltaic module 20 above, but also enable the opening of the buffer space 3 below to be positioned outside the edge of the photovoltaic module 20, so that the opening of the buffer space 3 is positioned in the area with smaller stress of the cushion block 10, and the influence of the buffer space 3 on the supporting strength of the cushion block 10 is reduced; the structure that the upper section of the second side 2 is opened and the lower section is closed can form a surrounding on the edge of the suspension edge 201 of the photovoltaic module 20 above, so that the photovoltaic module 20 can be reliably fixed, and the closed section can be positioned in a region with larger stress of the cushion block 10, so that the photovoltaic module 20 below can be reliably supported.

Further, along the direction that the first side 1 points to the second side 2, the height of at least one section of the clamping space 4 gradually decreases to increase the distance between the effective force application point of the clamping action and the first side 1, so that the effective force application point of the clamping action is closer to the inner side of the photovoltaic module 20, thereby improving the clamping action force.

Further, the clamping space 4 is surrounded by a first wall 41, a second wall 42 and a connecting wall 43, the first wall 41 and the second wall 42 are opposite to each other, so that the first wall 41 and the second wall 42 clamp the upper and lower sides of the photovoltaic module 20, and the photovoltaic module 20 and the cushion block 10 are prevented from moving relatively in the vertical direction; the connecting wall 43 is located on the first side 1, the connecting wall 43 connects the first wall 41 and the second wall 42, so as to form a clamping space 4 with an opening on the second side 2, and the connecting wall 43 can also limit the relative position of the cushion block 10 and the photovoltaic module 20 along the horizontal direction, so that the photovoltaic module 20 is located within the supporting and buffering action range of the cushion block 10; the connecting wall 43 extends in the vertical direction, so that the connecting wall 43 is parallel to the edge of the photovoltaic module 20, and the limit reliability is increased. The edges of the connecting wall 43 and the photovoltaic module 20 may abut against each other, and a gap may be formed between the connecting wall 43 and the edge of the photovoltaic module 20.

Further, the first wall 41 is located above the second wall 42, and the first wall 41 is gradually inclined towards the direction close to the second wall 42 along the direction away from the connecting wall 43, so as to avoid the contact stress between the photovoltaic module 20 and the first wall 41 when the photovoltaic module 20 is deformed by the downward force, and increase the risk of damage to the photovoltaic module 20. Specifically, when the photovoltaic module 20 is subjected to downward force such as stepping, the middle of the photovoltaic module 20 is bent downward, the edge of the photovoltaic module 20 is warped upward, and the closer to the edge of the photovoltaic module 20, the greater the degree of buckling deformation, the first wall 41 of this embodiment adopts a gradient design with gradually changed height, so that the first wall 41 is adapted to the buckling deformation trend of the photovoltaic module 20, thereby reducing or avoiding the contact stress between the photovoltaic module 20 and the first wall 41.

Further, the end of the first wall 41 away from the connecting wall 43 is configured in a circular arc shape, that is, the first wall 41 and the photovoltaic module 20 form an arc contact, so that contact stress is dispersed, and scratch or abrasion on the surface of the photovoltaic module 20 is avoided.

Further, when the first wall 41 is located above the second wall 42, an avoidance groove 421 is formed on a side of the second wall 42, which is close to the connecting wall 43, and the avoidance groove 421 is recessed on the surface of the second wall 42, so as to avoid contact stress generated between the photovoltaic module 20 and the second wall 42 when the photovoltaic module 20 is deformed by an upward force, and increase the risk of damage to the photovoltaic module 20. Specifically, when the photovoltaic module 20 receives an upward force such as wind force, the middle part of the photovoltaic module 20 is bent downward, the edge of the photovoltaic module 20 is bent downward, and the avoidance groove 421 is formed, so that the photovoltaic module 20 is bent downward in the avoidance groove 421, and the contact stress between the photovoltaic module 20 and the second wall 42 is reduced or avoided.

Further, the groove width of the avoidance groove 421 is gradually increased along the bottom-up direction, so that the shape of the avoidance groove 421 is adapted to the stress action range of the warpage of the photovoltaic module 20. That is, the more the upper position is, the larger the stress acting range of the warpage of the photovoltaic module 20 is, the lower the stress acting range of the warpage of the photovoltaic module 20 is, and the avoidance groove 421 of the embodiment adopts the structural design of gradually changing groove width, so that the avoidance groove 421 is adapted to the stress acting range of the warpage of the photovoltaic module 20, thereby not only achieving reliable support, but also effectively avoiding contact stress.

Further, the groove wall of the avoidance groove 421 comprises a vertical wall surface, the vertical wall surface is a wall surface of the avoidance groove 421 close to the connecting wall 43, so that a larger deformation space is formed at the edge position of the photovoltaic module 20, when the photovoltaic module 20 is prevented from warping, the edge of the photovoltaic module 20 and the vertical wall surface interfere with each other, the vertical wall surface can be located on the same plane with the connecting wall 43, the vertical wall surface can also be located on different planes with the connecting wall 43 to form a step, and the avoidance groove 421 is located below the edge of the photovoltaic module 20, so that the edge of the photovoltaic module 20 forms a suspension design.

Further, the groove wall of the relief groove 421 includes a flared wall 422, the flared wall 422 is disposed opposite to the connection wall 43, that is, the flared wall 422 is a wall surface of the relief groove 421 away from the connection wall 43; the flared wall 422 is gradually inclined away from the connecting wall 43 in a bottom-up direction so that the shape of the relief groove 421 is adapted to the range of the force of the warpage of the photovoltaic module 20.

Further, the slope of the flared wall 422 is 15 ° to 75 °, for example, the slope of the flared wall 422 may be 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 ° or 70 °, so as to not only enable the cushion block 10 to provide a stable supporting effect, but also reduce or avoid stress generated by warping of the photovoltaic module 20. When the slope of the flared wall 422 is smaller than 15 °, the action point of the second wall 42 and the photovoltaic module 20 is too far away from the first side 1, so that the spacer 10 is easy to incline to one side; when the slope of the flared wall 422 is greater than 75 °, greater stress may still be generated with the second wall 42 when the edge of the photovoltaic module 20 is warped downward.

Specifically, the flared wall 422 may be provided as a slope or a curved surface. When the flared wall 422 is set to be an inclined plane, the slope of the flared wall 422 is the angle between the inclined plane and the horizontal plane; when the flared wall 422 is configured as a curved surface, the slope of the flared wall 422 is the angle between the tangent line of the curved surface and the horizontal plane.

Further, the second wall 42 is designed with an arc surface, and the highest point of the arc surface is located in the middle of the second wall 42, that is, the second wall 42 is only propped against the photovoltaic module 20 at the highest point of the arc surface, and gaps are left between the second wall 42 and the photovoltaic module 20 at two sides of the highest point, so that the supporting acting force between the photovoltaic module 20 and the second wall 42 is as close to the central position of the cushion block 10 as possible, the stress on two sides of the cushion block 10 is uniform, and the cushion block 10 is prevented from tilting on one side. It will be appreciated that the second wall 42 may be provided in other configurations such as planar.

Further, the buffer space 3 includes a first buffer 31 and a second buffer 32; the first buffer area 31 penetrates through the first side 1 of the cushion block 10, so that the first buffer area 31 forms an opening structure, and the cushion block 10 has larger deformation capacity in the first buffer area 31, so that larger deformation degree of the photovoltaic module 20 is matched; the second buffer area 32 is located at the inner side of the first buffer area 31, and a supporting portion 33 is arranged between the first buffer area 31 and the second buffer area 32, so that the second buffer area 32 forms a closed structure, and the cushion block 10 has smaller deformation capacity in the second buffer area 32, so that smaller deformation degree and stronger supporting effect of the photovoltaic module 20 are matched.

Further, the cross-sectional shape of the second buffer area 32 is any one of a circle, a triangle, a rectangle, or a pentagon. It should be understood that the cross-sectional shape of the second buffer area 32 may be any shape, such as a hexagon, or may be any irregular shape, so long as the cushion block 10 is locally deformed. The circular cross section is simple in structure, has no stress concentration point, and can effectively adjust acting force in all directions; the triangular section has higher stability, and difficult deformation such as crushing and the like which are difficult to recover is not easy to generate; the rectangular cross section can form uniform deformation in a larger area; the cross section of the polygons such as pentagons is not easy to generate stress concentration.

Further, the wall surface (e.g., the first wall 41, the second wall 42 or the connecting wall 43) surrounding the holding space 4 may be provided with a first adhesive layer (not shown in the figure) for adhesively fixing the photovoltaic module 20, that is, adhesively fixing the photovoltaic module 20 in the holding space 4 through the first adhesive layer, thereby increasing the reliability of the connection of the photovoltaic module 20 with the cushion block 10. The bottom surface of the cushion block 10 may be provided with a second adhesive layer (not shown in the figure), and the second adhesive layer is used for adhesively fixing the color steel tile, that is, the cushion block 10 is adhesively fixed on the color steel tile through the second adhesive layer, so as to prevent the cushion block 10 from generating relative movement or collision with the color steel tile.

Further, the cushion block 10 is made of any one of silica gel, silicone rubber, fluorosilicone rubber or nitrile rubber, that is, the cushion block 10 is made of an elastic and anti-aging material, so that the cushion block 10 has elastic deformation capacity, the cushion block 10 forms a flexible support for the photovoltaic module 20, stress damage caused by rigid contact is avoided, and the cushion block 10 has a long service life under sunlight irradiation.

As shown in fig. 4-7, the embodiment of the present utility model further provides a photovoltaic component, which includes a color steel tile, a plurality of fixtures 30, a photovoltaic module 20, and any one of the cushion blocks 10 provided in the embodiment of the present utility model. The plurality of clamps 30 are connected with the color steel tile, the photovoltaic module 20 is clamped and fixed on the color steel tile through the plurality of clamps 30, the cushion block 10 is arranged between the photovoltaic module 20 and the color steel tile, and the cushion block 10 is used for supporting and limiting the lower side of the photovoltaic module 20, so that the deformation degree of the edge of the photovoltaic module 20 is reduced.

The plurality of clamps 30 may be uniformly distributed along the first direction X and/or the second direction Y, and in the embodiment of the present utility model, the plurality of clamps 30 are uniformly distributed along the second direction Y is described as an example. It should be understood that the distribution direction of the fixture 30 may be specifically set according to the size, shape and placement position of the photovoltaic module 20, and the placement of the fixture 30 is not specifically limited in the present utility model.

In one embodiment, as shown in fig. 4-7, along the edges of the photovoltaic module 20, the photovoltaic module 20 includes a clamping edge and a hanging edge 201, the clamping edge is connected to the fixture 30, and the spacer 10 is disposed between the color steel tile and the hanging edge 201.

After the clamp 30 is clamped and fixed with the clamping edge of the photovoltaic module 20, the clamping edge is pressed downwards along the third direction Z, and the suspended edge 201 between the two clamping edges is bent and deformed, so that stress concentration is easily generated at the critical position of the suspended edge 201 and the clamping edge, and the risk of hidden cracking or breaking of the photovoltaic module 20 is caused.

In this embodiment, as shown in fig. 4, the cushion block 10 is disposed between the suspended edge 201 and the color steel tile, so as to provide enough supporting force for the suspended edge 201, thereby reducing the bending deformation degree of the suspended edge 201 after the clamp 30 and the clamping edge of the photovoltaic component 20 are clamped and fixed, and reducing the stress at the critical position of the suspended edge 201 and the clamping edge, thereby reducing the risk of hidden crack or breakage of the photovoltaic component 20 due to too concentrated stress at the position, and improving the service life and the working stability of the photovoltaic component. And the arrangement quantity and the occupied space of the cushion blocks 10 on the color steel tiles and/or the photovoltaic modules 20 can be reduced, so that the reasonable utilization rate of the installation space on the color steel tiles is improved, and the cost is saved.

In one embodiment, as shown in fig. 4 and 5, the spacer 10 is disposed at least at one side of the jig 30 in the distribution direction of the jig 30.

In this embodiment, as shown in fig. 4 and 5, the cushion block 10 is at least disposed at one side of the fixture 30, so that after the fixture 30 and the clamping edge of the photovoltaic module 20 are clamped and fixed, the cushion block 10 can be supported on at least a portion of the suspended edge 201 of the photovoltaic module 20, thereby reducing the bending deformation degree of the suspended edge 201.

Specifically, along the distribution direction of the clamps 30, for example, the second direction Y shown in fig. 4 and 5, the pad 10 is disposed only on the left side of the clamps 30 as shown in the specific embodiment shown in fig. 2, and may be disposed only on the right side of the clamps 30, i.e., only one pad 10 is disposed between two adjacent clamps 30.

Of course, as shown in the embodiment of fig. 5, the cushion blocks 10 may be disposed on two sides of the clamps 30, that is, two cushion blocks 10 are disposed between two adjacent clamps 30, so as to further increase the supporting area of the suspended edge 201 and prevent the suspended edge from bending deformation. And compared with the method of using only one cushion block 10 with larger volume, the method has the advantages that the two cushion blocks 10 are respectively supported at the two ends of the suspension edge 201, which are close to the clamp 30, so that the volume and occupied space of the cushion blocks 10 can be reduced, and the cost is further reduced.

The length dimension of the cushion block 10 along the second direction Y may be greater than 0, less than or equal to the distance between two adjacent clamps 30, and may be specifically designed according to the specific structure of the photovoltaic component, which is not limited herein.

Preferably, the length dimension of the cushion block 10 may be 20mm, so that the cushion block 10 can be moderate in volume while a sufficient supporting area can be provided for the suspended edge 201 of the photovoltaic module 20, and the installation space of a single cushion block 10 is saved, so that the arrangement and installation of a plurality of cushion blocks 10 are facilitated, and meanwhile, the manufacturing cost can be saved.

In another embodiment, as shown in fig. 5, the pads 10 may be symmetrically disposed at both sides of the jig 30 along the distribution direction of the jig 30.

In this embodiment, as shown in fig. 5, the cushion blocks 10 are symmetrically arranged on two sides of the fixture 30, so that the suspended edge 201 of the photovoltaic module 20 between the two fixtures 30 can be supported near two ends of the fixture 30 on two sides, and the stress of the suspended edge 201 is more uniform, so that the supporting strength of the cushion block 10 to the suspended edge 201 is further improved, and the supporting design of the cushion block 10 with smaller volume can be realized when the size of the suspended edge 201 is fixed, and the manufacturing cost is further reduced.

In another embodiment, as shown in fig. 6, at least three pads 10 are disposed between two adjacent clamps 30 along the distribution direction of the clamps 30.

In this embodiment, as shown in fig. 6, in this structure, the suspended edge 201 between two adjacent clamps 30 is supported by multiple points of at least three pads 10, so that a smaller volume design of the pads 10 can be achieved. And the multipoint support design is more flexible, and the specific installation position of the cushion block 10 can be correspondingly adjusted according to the length of the suspended edge 201, so that the application range of the cushion block 10 can be improved, the cushion block 10 can be suitable for various types and sizes of photovoltaic components, and the manufacturing cost is saved.

In a specific embodiment, as shown in fig. 7, the photovoltaic module 20 further includes a corner 202, and the corner 202 and the color steel tile support are provided with a cushion block 10.

In this embodiment, as shown in fig. 7, the cushion block 10 is supported at the corner of the photovoltaic module 20, so as to further improve the flatness of the photovoltaic module 20, prevent the corner 202 from bending or deforming during long-time use, ensure the reliable function of the photovoltaic module 20, and improve the service life and the working stability of the photovoltaic module 20.

In one embodiment, as shown in fig. 4-7, a first gap 40 is provided between the pad 10 and the clamp 30, the first gap 40 being the smallest gap between the pad 10 and the clamp 30.

In this embodiment, as shown in fig. 4-7, a first gap 40 is provided between the cushion block 10 and the fixture 30, so that installation of the cushion block 10 is facilitated, and assembly efficiency of the photovoltaic component is improved.

In one embodiment, as shown in FIGS. 4-7, the first gap 40 has a distance L1, 0.ltoreq.L1.ltoreq. 316.75mm. For example, L1 may be 5mm, 10mm, 15mm, 20mm, 25mm, 50mm, 75mm, 100mm, 200mm, 300mm, etc., and of course may be other dimensions, and the specific dimensions of L1 may be designed according to the specific structure of the photovoltaic member, without limitation.

Along the second direction Y, if the distance L1 between the first gap 40 is too large, i.e., L1 > 316.75mm, the distance between two adjacent clamps 30 needs to be set larger, and the length of the suspended edge 201 is too large, so that the suspended edge 201 is easier to generate bending deformation along the third direction Z under the action of gravity, and the distance L1 between the cushion block 10 and the clamps 30 between the first gap 40 is too large, so that the support between the suspended edge 201 and the adjacent positions of the clamps 30 is unreliable, the suspended edge 201 above the first gap 40 is easy to generate bending deformation along the third direction Z, and the stress between the suspended edge 201 and the adjacent positions of the clamps 30 cannot be reduced, so that the photovoltaic module 20 is easy to generate hidden crack and damage risk.

In this embodiment, as shown in fig. 4-7, the distance L1 of the first gap 40 satisfies 0.ltoreq.l1.ltoreq. 316.75mm, the distance L1 of the first gap 40 between the pad 10 and the fixture 30 is moderate, and the support at the adjacent position of the suspended edge 201 and the fixture 30 is more reliable, so that the suspended edge 201 above the first gap 40 is not easy to generate bending deformation along the third direction Z, thereby playing the role of reducing the stress at the adjacent position of the suspended edge 201 and the fixture 30, reducing the risk of hidden crack and damage of the photovoltaic module 20, and improving the service life and the working stability of the photovoltaic component.

Preferably, the distance L1 of the first gap 40 is 0.ltoreq.l1.ltoreq.20mm, so as to further ensure that the suspended edge 201 above the first gap 40 can be sufficiently supported, prevent the suspended edge 201 thereat from bending deformation along the third direction Z, and avoid hidden crack and damage risks caused by too concentrated stress of the suspended edge 201 at the photovoltaic module 20.

In one embodiment, as shown in fig. 5-7, a second gap 50 is provided between two adjacent pods 10.

In this embodiment, as shown in fig. 5 to 7, the second gap 50 may avoid interference between two adjacent cushion blocks 10, so as to facilitate installation of the cushion blocks 10, and prevent the cushion blocks 10 installed in the installation process from loosening and falling due to interference of the cushion blocks 10 being installed, thereby improving the assembly efficiency of the photovoltaic component. In addition, the number of the cushion blocks 10 can be reduced by setting the second gaps 50, so that the support area can be uniformly and sufficiently provided for the suspended edge 201, the installation space of the cushion blocks 10 is reduced, the space utilization rate of the photovoltaic component is improved, and the cost is further saved while the reliability of the support strength is ensured.

In one embodiment, as shown in FIGS. 5-7, the distance of the second gap 50 is L2, 0.ltoreq.L2.ltoreq.613.5 mm. For example, L2 may be 5mm, 10mm, 15mm, 20mm, 25mm, 50mm, 75mm, 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, etc., and of course may be other dimensions, and the specific dimensions of L2 may be designed according to the specific structure of the photovoltaic member, without limitation.

Along the second direction Y, if the distance L2 of the second gap 50 is too large, that is, L2 is greater than 613.5mm, the distance between the two adjacent clamps 30 needs to be set larger, and the length of the suspended edge 201 is too large, so that the suspended edge 201 is easier to generate bending deformation along the third direction Z under the action of gravity of the suspended edge itself, and the distance L2 of the second gap 50 between the two adjacent cushion blocks 10 is too large, so that the suspended edge 201 between the two adjacent cushion blocks 10 lacks support, and the suspended edge 201 between the two adjacent cushion blocks 10, that is, the suspended edge 201 above the second gap 50 is easy to generate bending deformation along the third direction Z under the action of gravity of the suspended edge itself, thereby reducing the service life and the working stability of the photovoltaic module 20.

In this embodiment, as shown in fig. 5-7, the distance L2 of the second gap 50 satisfies 0.ltoreq.l2.ltoreq.613.5 mm, and the distance of the second gap 50 between two adjacent cushion blocks 10 is moderate, so that the suspended edge 201 between two adjacent cushion blocks 10 can be sufficiently supported, and thus the suspended edge 201 located above the second gap 50 is not easy to generate bending deformation along the third direction Z, which ensures the overall flatness of the photovoltaic module 20, and improves the service life and the working stability of the photovoltaic module 20.
