BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a solar device.

Description of the Prior Art

In recent years, more and more countries encourage people to use green energies (for example, solar power) to replace traditional energies (for example, nuclear power, fossil fuels and others). The solar device is mainly used to absorb sunlight and convert to electricity to use by setting a solar penal on a roof of a building or on a solar power support frame.

In prior arts, the solar penal includes a base seat and a support frame which is disposed on the base seat, and the support frame is for the solar penal to be disposed thereon. However, the support frame of the conventional solar penal is made of aluminum alloy which has a poor buffering effect; therefore, when the solar penal is disposed on the base seat, the support frame may swing or shake due to an external force, and the solar penal may not be stably supported.

SUMMARY OF THE INVENTION

The major object of the present invention is to provide a solar device, which provides buffering effect and stable support.

To achieve the above and other objects, a solar device is provided, including: a solar panel assembly which includes a solar panel and a strut, and the solar panel has a solar power conversion face and a connecting portion which is connected to the strut; and a support device which includes a base seat, an engaging portion and a rubber elastic portion, the base seat has a plurality of threaded structures for being screwed to a base surface, the engaging portion is connected to the strut, and the rubber elastic portion is connected to and between the base seat and the engaging portion.

The support device10includes a base seat11, the engaging portion30and a rubber elastic portion40, the base seat11has a plurality of threaded structures12for being screwed to a base surface2(the base surface2may be, for example, a ground surface such as cement surface or a support surface of a transferring device); and the rubber elastic portion40is connected to and between the base seat11and the engaging portion30. In this embodiment, the solar penal assembly20further includes a frame25, the solar penal21is disposed on the frame25, and the strut22may be connected to the frame25to restrict a movement range of the solar penal21so as to provide buffering, wind-resistant and earth-resistant effects to stably support the solar device1. In other embodiments, the strut may further include a universal joint.

In addition, in the present invention, a number of the support device10which can be disposed to one said solar penal assembly20is not limited. For example, one said solar penal assembly20may have either one said support device10or a plurality of the support devices10. Besides, a number of the frame22which can be disposed on one said solar penal21is not limited.

In this embodiment, the base seat11further includes a cement seat13and a base14which is screwed to the cement seat13, the plurality of threaded structures12are formed on the base14, and in this embodiment, each said threaded structure12is a threaded hole; more specifically, the cement seat13can be tightly fixed on the base surface2. Specifically, the base14has the plurality of threaded structures12for a plurality of screws to be screwed and connected to the cement seat13so that the base14can be stably supported and easily disassembled. In addition, the base seat11is greater than the rubber elastic portion40in outer diameter for providing stable support.

The rubber elastic portion40has a curved protrusive section41which extends radially to provide buffering effect and support. In this embodiment, the rubber elastic portion40is a rubber body which is solid; in other embodiments, the rubber elastic portion may be a rubber body which is hollow, or the rubber elastic portion may include a support rod which is connected to the base seat and the engaging portion and a rubber body which is connected to the base seat and the engaging portion, and the rubber body is circumferentially disposed around the support rod.

The rubber elastic portion40further has at least one annular groove42. In this embodiment, a number of the at least one annular groove42is two, the two annular grooves42are formed on two opposite sides of the curved protrusive section41on an axial direction so that the curved protrusive section41can be elastically pressed toward each of the two annular grooves42to elevate the buffering effect. In addition, the rubber elastic portion40further has a plurality of rib portions43, each said rib portion43is saddled on the at least one annular groove42and connected to two opposite sides of the at least one annular groove42to provide more preferable and stable support. Specifically, each said rib portion43is saddled on one of the two annular grooves42and extends toward the axial direction, and preferably, at least one part of each said rib portion43is inserted within the at least one annular groove42to provide support strength.

Preferably, the rubber elastic portion40has a radially outmost point, and the curved protrusive section41radially protrudes beyond the radially outmost point to provide greater buffering strength and support.

The solar device1further includes an elastic sleeve50, the elastic sleeve50is sleeved on the rubber elastic portion40, and the elastic sleeve50is non-contact with the rubber elastic portion40. Preferably, the elastic sleeve50and the rubber elastic portion40are non-contact with each other radially to increase deformation and movement ranges of the elastic sleeve50. An elastic coefficient of the elastic sleeve50and an elastic coefficient of the rubber elastic portion40are different to provide different buffering effect. In other embodiments, the elastic sleeve and the rubber elastic portion may have the same elastic coefficient. In this embodiment, the elastic sleeve50has an inner protrusive flange51extends radially, and the inner protrusive flange51covers the rubber elastic portion40on an axial direction to provide better protection and prevent the rubber elastic portion40from being damaged.

In addition, the engaging portion30further includes a protrusive flange31which extends radially, and the rubber elastic portion40is disposed between the protrusive flange31and the base seat11to elevate support strength. Furthermore, the engaging portion30further includes a tube34, the strut22is detachably connected to the tube34, and an inner wall of the tube34has a plurality of engaging protrusions32. In this embodiment, each said engaging protrusion32has at least one threaded hole33so that the strut22can be disposed through or sleeved on the tube34, and the tube34, the strut22and the threaded hole33can be screwed via bolts to be detachably positioned.

Preferably, the rubber elastic portion40has a recess44, the tube34and the protrusive flange31are engaged within the recess44, and a wall of the recess44overlaps with the protrusive flange31radially to be stably engaged with each other.

In this embodiment, the rubber elastic portion40has the connecting recess47, and the base14has the connecting protrusion15to increase the engaging strength of the base14and the rubber elastic portion40.

Please refer toFIG. 5, the difference between a second preferred embodiment and the first embodiment is that the curved protrusive section41further has a plurality of slots45which extend circumferentially and a plurality of elastic bodies46, and each said elastic body46is disposed within each said slot45; and an elastic coefficient of the plurality of elastic bodies46and an elastic coefficient of the rubber elastic portion40are different to increase the buffering effect. In other embodiments, each said elastic body may be a metal sheet to provide better support.

Given the above, the rubber elastic portion of the support device can provide buffering, wind-resistant and earth-resistant effects to stably support the solar device.
