The invention can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Drawings will be used below to disclose a plurality of embodiments of the present invention. For the sake of clear illustration, many practical details will be explained together in the description below. However, it is appreciated that, the practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, the practical details are not essential. Moreover, for the sake of drawing simplification, some customary structures and elements in the drawings will be schematically shown in a simplified way.
The words “about”, “around” or “approximately” used in this article, generally refers to a value of tolerance or range within 20%, more preferably within 10%, and most preferably within 5%. If it is not stated expressly in the article, all the values mentioned are regarded as approximate values, having the tolerance or range as presented by “about”, “around” or “approximately”.
In the present embodiment, the quantity for the column member 120 and the adapter member 130 both is 4, and the column member 120 and the adapter member 130 are respectively installed at the four corners of the frame member 110. Moreover, the column member 120 located at one side (for example the front side) of the frame member 110 is shorter than the column member 120 at the other side (for example the back side) of the frame member 110, leading to an inclination of the frame member 110 at a predetermined angle relative to the floor, such that the solar cell lamination installed thereon can receive the sun light. It is appreciated that, the quantity and the dimension relation of the column member 120 and the adapter member 130 as described above are illustrative only, and are not used for the limitation of the present invention. The person having ordinary skill in the art of the present invention should, based on the actual needs, flexibly choose the embodiment of the column member 120 and the adapter member 130.
In the present design, when the frame member 110 has accommodated the solar cell lamination, an axial force of the column member 120 can fully support the frame member 110 and the solar cell lamination, so as to reduce the risk of permanent deformation of the column member 120 or the adapter member 130. Moreover, as the axial force of the column member 120 can fully support the frame member 110 and the solar cell lamination, the capacity of the whole system to withstand wind pressure or snow pressure is also increased.
In the present embodiment, the location of the vertical projection of the first wall 113 on the surface where the end surface 122 is located can overlap with the outer edge 123. However, this does not limit the present invention. The person having ordinary skill in the art of the present invention should, based on the actual needs flexibly choose the position of the first wall 113.
Please keep referring to
Specifically, the quantity of the fixing plate 132 above-mentioned is 2, for example, a fixing plate 132a and a fixing plate 132b. The fixing plate 132a, the fixing plate 132b and the part of the supporting plate 131 therebetween cooperate to define a cross section in a substantially reverse “U” shape (or, n shape), to restrain the column member 120 between the fixing plate 132a and the fixing plate 132b. The first fastener 133 is used for connecting and fixing the fixing plate 132a, the column member 120 and the fixing plate 132b, to securely fix the relative position of the column member 120 and the adapter member 130. In the present embodiment, the fastener 133 can be a bolt, a pin, a screw, or other suitable fasteners.
In the present embodiment, the frame member 110 further includes a third flange 114 and a second wall 115. The third flange 114 is substantially parallel with the second flange 112 and is located below the second flange 112 for abutting against the supporting plate 131 of the adapter member 130. The second wall 115 and the first wall 113 are parallel and connected at the junction with the second flange 112, and the second wall 115 connects to the second flange 112 and the third flange 114. The third flange 114 has a first wing 114a and a second wing 114b. The first wing 114a and the second flange 112 extend towards approximately the same direction along the direction approximately perpendicular to the second wall 115, i.e., extend towards the inside of the frame member 110. The second wing 114b extends in a direction opposite to that of the second flange 112 along the direction approximately perpendicular to the second wall 115, i.e., extend towards the outside of the frame member 110. The junction of the third flange 114 and the second wall 115 is the junction of the first wing 114a and the second wing 114b, and the first wing 114a and the second wing 114b extend in the opposite directions with regard to the junction of the second wall 115.
Moreover, the frame member 110 of the present embodiment further includes a fourth flange 116 and a third wall 117. The fourth flange 116 connects to the second wall 115. The fourth flange 116 is substantially parallel with the third flange 114 and is located above the second wing 114b of the third flange 114. The third wall 117 connects to the fourth flange 116 and the second wing 114b of the third flange 114, such that at least a part of the second wall 115, the second wing 114b of the third flange 114, the third wall 117 and the fourth flange 116 cooperate to form a hollow frame section. The first flange 111, the second flange 112, the third flange 114 and the fourth flange 116 of the frame member 110 above-mentioned are substantially horizontal members, and the first wall 113, the second wall 115 and the third wall 117 are substantially vertical members.
In the present embodiment, a vertical height H1 of the fourth flange 116 to the second wing 114b of the third flange 114 is less than a vertical height H2 of the second flange 112 to the first wing 114a of the third flange 114. However, this does not limit the present invention. The person having ordinary skill in the art of the present invention should, based on the actual needs, flexibly choose the relative position of the fourth flange 116 and the second flange 112.
Moreover, in the present embodiment, in order to strengthen the bending resistance of the frame member 110, the manufacturer can choose to install a stiffener 118 between the second flange 112 and the first wing 114a of the third flange 114. It is appreciated that, the stiffener 118 is not an essential element, if the strength of the frame member 110 is enough, the stiffener 118 can be optionally omitted and not installed.
In the present embodiment, in order to securely make use of the axial force of the column member 120 to support the frame member 110 and the solar cell lamination, the locations of the vertical projection of both the second wall 115 and the stiffener 118 on the surface where the end surface 122 is located fall on the end surface 122. More specifically, the location of the vertical projection of the second wall 115 above-mentioned on the end surface 122 falls on the distal half portion II. That is, compared to the inner edge 121, the outer edge 123 is closer to the position of the vertical projection of the second wall 115 on the end surface 122. The location of the vertical projection of the stiffener 118 above-mentioned on the end surface 122 falls on the proximal half portion I. That is, compared to the outer edge 123, the inner edge 121 is closer to the position of the vertical projection of the stiffener 118 on the end surface 122.
In the present embodiment, the supporting plate 131, the second wing 114b of the third flange 114 and the fourth flange 116 have respectively a through hole THa, a through hole THb and a through hole THc therein. The second fastener 134 is used for passing through together the through hole THa, the through hole THb and the through hole THc, for connecting and fixing the supporting plate 131, the second wing 114b of the third flange 114 and the fourth flange 116, to fix the relative position of the frame member 110 and the adapter member 130. The second fastener 134 above-mentioned can be a bolt, a pin a screw, or other suitable fasteners.

In the present embodiment, since the nut 135 cannot move in the vertical direction due to the restraints of the first fixing wing 136 and the second fixing wing 137, such that the bolt (i.e., the second fastener 134) as locked in the nut 135 cannot move in the vertical direction neither. Thus, a nut is not necessary on the fourth flange 116, saving the assembly process. Moreover, since the weight of the solar cell lamination and the frame member 110 is heavy so much, thus, even if no bolt is fixed on the fourth flange 116, the frame member 110 is uneasy to detach from the bolt (i.e., the second fastener 134).
Certainly, the assembler can choose to refit the nut 135 on the fourth flange 116, or to install the nut 135 below the supporting plate 131 and on the fourth flange 116 as well. Moreover, in the embodiment which the nut 135 is refitted on the fourth flange 116 (i.e., the nut 135 is installed only on the fourth flange 116, but not below the supporting plate 131), or the second fastener 134 as a pin, the adapter member 130 does not need to have the first fixing wing 136, the second fixing wing 137 and the fixing wall 138. Moreover, if the thickness of either the frame member 110 or the adapter member 130 is thick enough for threading, the assembler can choose to thread on the frame member 110 and/or the adapter member 130 to directly lock the bolt (i.e., the second fastener 134) on the thread, while it is unnecessary to install the nut 135. The person having ordinary skill in the art of the present invention should, based on the actual needs, flexibly choose the embodiment of the adapter member 130.
In the present embodiment, the adapter member 130 can include a screwing member. The screwing member is disposed on the frame member 110 for connecting with the second fastener 134 to fix the frame member 110 and the adapter member 130. The screwing member contacts with the frame member 110 by breaking through the insulation layer 140. For example, in
It is appreciated that, although
In the embodiment above, the material of the frame member can be metal, such as aluminum alloy, steel, stainless steel and combinations thereof. The manufacturing method of the frame member 110 can be forging, casting and combinations thereof. Certainly, if there is no concern about the material and the shape of the frame, the frame member 110 can also choose to firstly produce as strips by the method of aluminum extrusion, and then using these strips to form the frame member 110. From the structural point of view, the first flange 111, the second flange 112, the first wall 113, the third flange 114, the second wall 115, the fourth flange 116, the third wall 117 and the stiffener 118 above-mentioned, are an integrated element.
Moreover, the material of the adapter member 130 above-mentioned can be metal, such as aluminum alloy, steel, stainless steel and combinations thereof. The manufacturing method of the adapter member 130 can be forging, casting and combinations thereof. From the structural point of view, the supporting plate 131, the fixing plates 132, the first fixing wing 136, the second fixing wing 137 and the fixing wall 138 above-mentioned, are an integrated element, while the first fastener 133, the second fastener 134 and the nut 135 (if any) are independent elements.
Furthermore, the material of the column member 120 above-mentioned can be metal, such as aluminum alloy, steel, stainless steel and combinations thereof. The manufacturing method of the column member 120 can be forging, casting and combinations thereof.
The examples of the present invention are disclosed below, so as to illustrate that the supporting assembly of the embodiment above-mentioned can surely provide the performance required. It is appreciated that, in the description below, the parameters already mentioned in the embodiments above are not repeatedly described, and supplement are added only when further definition is required, as stated in advance.
In the example below, the supporting assembly in the first embodiment is mainly adopted. Only in the present example, a nut is installed below the supporting plate 131 and also on the fourth flange 116. The material of the frame member 110 is aluminum alloy (AL5052H32 or AL6063T5), the supporting plate 131, the fixing plate 132, the first fixing wing 136, the second fixing wing 137 and the fixing wall 138 is an integrated aluminum alloy (AL5052H32 or AL6063T5). The materials of the first fastener 133, the second fastener 134 and the nut 135 are all stainless steel (SUS304). The elastic modulus, the yield strength and the fracture strength are shown in Table 1 below.
Under the conditions above, the front side of the simulated solar cell lamination withstands a uniform pressure of 5400 Pa. The result shows that each element of the supporting assembly does not have the risk of fracture, surely being able to withstand a uniform pressure of 5400 Pa.
