In Fig. 2,3, shown the back mounting rail 100 according to a kind of preferred implementation of the application, it comprises main body 10 and fixed part 20 substantially.Main body 10 is made up of injection-moulding plastic, the material that is suitable for making main body 10 can comprise: PET (PETG), PBT (polybutylene terephthalate), PTT (PTT), PA6 (polycaprolactam), PA66 (polyamide 66), PA46 (polyamide 46), PAR (Nomex), PC (Merlon), ABS (acrylonitrile/butadiene/styrene copolymer), PU (polyurethane), PPO (polyphenylene oxide), LCP (polymeric liquid crystal copolymer), PEI (Polyetherimide), or its blend etc.
Main body 10 mainly comprises tabular base portion 12 and is integrally formed with base portion 12 and from the described base portion jut 14 of projection backward.Base portion 12 shown in figure is roughly the form of rectangular slab, and the form of the plate of other shape also can adopt certainly.
Base portion 12 has front surface (sightless surface in Fig. 2,3) and rear surface (visible surface in Fig. 2,3), and described front surface is configured to be suitable for being bonded in by adhesive the back side of cell panel.
Jut 14 has towards the front end of base portion 12 with back to the rear end of base portion 12, and described front end is incorporated into the rear surface of base portion 12, and described rear end constructs the rear end face 16 that is suitable for the support body supports that is used to support cells plate.Jut 14 can be solid (advantage is that intensity is high) or hollow (advantage is to save material).
In order to strengthen the intensity of base portion 12, the periphery 18 of base portion 12 can be formed with the edge of digging backward.In addition, on the rear surface of base portion 12, can form reinforcement (not showing in Fig. 2,3).Some in described reinforcement are connected between base portion 12 and jut 14, to strengthen the two bonding strength and rigidity.
According to the application basic conception, the front surface (being the front surface of base portion 12) of described main body 10 is for the bonding and support cells plate with the back side of cell panel, and its rear surface (being the rear end face 16 of jut 14) is resisted against on supporter and the carrying of supported body.For enough supports are provided to cell panel, base portion 12 should be enough large, and for example, the area being limited by the periphery 18 of base portion 12 is 100cm
2to 3000cm
2, be preferably 250cm
2to 1000cm
2.
On the other hand, the rear end face 16 of jut 14 can be designed to less of to save as far as possible material, therefore, the area that the periphery of the rear end of jut 14 limits is less than the area that the periphery 18 of (preferably much smaller than) base portion 12 limits, for example, the area that the periphery of the rear end of described jut 14 limits is 1/40 to 4/5 with the ratio of the area that the periphery of described base portion 12 limits, and is preferably 1/10 to 1/2.
The area that the periphery 18 that the area that the periphery of the front end of jut 14 limits can be more than or equal to area that the periphery of the rear end of jut 14 limits, be less than or equal to base portion 12 limits.According to the example shown in figure, the front end of jut 14 is greater than rear end, and jut 14 is formed as the form of frustum thus.For the example of the essentially rectangular base portion 12 shown in figure, the elongated frustum of a pyramid of jut 14, along the longitudinal extension of base portion 12.
As an extreme example, the front end of jut 14 is identical with rear end area and shape.As an extreme example, the front end of jut 14 expands to the periphery 18 of base portion 12, and main body 10 forms the form of frustum (for example frustum of a pyramid) on the whole.
As a kind of comparatively practical design, the periphery of the front end of jut 14 is positioned at the periphery 18 of base portion 12 completely, as shown in FIG..Certainly, the periphery of the front end of jut 14 also can be positioned partially in the periphery 18 of base portion 12, can some overlap with the periphery 18 of base portion 12.For some particular application, certain or some positions of the periphery of the front end of jut 14 even can exceed the periphery 18 of base portion 12.
Described fixed part 20 is carried by jut 14, and described back mounting rail is arranged on supporter by fixed part 20.As shown in Figure 2, fixed part 20 is combined in jut 14, forms thus the complete back mounting rail 100 shown in Fig. 3.In Fig. 2, show for clear, fixed part 20 has been exaggerated some.
Fixed part 20 can be the material by jut 14 itself that form with parts jut 14 one, the material of fixed part 20 is identical with main body 10.Or fixed part 20 can be the individual component being formed by the material different from main body 10.For example, fixed part 20 can be made up higher than the plastics of main body 10 of intensity and/or elasticity, or is made of metal.
In the time that the material of fixed part 20 is identical with main body 10, can form the main body 10 with fixed part 20 by single injection moulding step, this has greatly simplified the manufacture process of back mounting rail 100.In this case, in fact fixed part 20 can be regarded as by a part for the material of jut 14 and form.
In the time that the material of fixed part 20 is different from main body 10, can first produce independent fixed part 20.Then, fixed part 20 is assembled to (such as bonding, welding, by means of securing member etc.) to main body 10 by additional number of assembling steps; Or in the process of injection molding of main body 10, by inlaying moulded fixed part 20 in main body 10.
