The synchronous expansion mechanism provided by the utility model comprises a fixed support and a moving support; two ends of the fixed support are respectively articulated with one ends of two second expansion arms; the other end of each second expansion arm is provided with a second gear; two ends of the moving support are respectively articulated with one ends of the two first expansion arms, and the other end of each first expansion arm is provided with a first gear; the first gears and the second gears are mutually meshed to form gear pairs; the middle part of the fixed support and the middle part of each second expansion arm are connected through a hydraulic push-and-pull rod; and the gear pairs at one side of two ends of the fixed support are connected through a flexible mechanism. According to the utility model, free expansion and contraction can be realized, and the synchronism between expansion and contraction is ensured.

Description

A kind of solar cell windsurfing synchronous expansion mechanism

Technical field

The utility model relates to a kind of solar cell windsurfing synchronous expansion mechanism.

Background technology

In field of solar thermal power generation, need need the folding transportation of solar panel behind the arrival assigned address, be launched to be used to receive sunlight again for convenient transportation, therefore, need to adopt development mechanism.

Chinese patent CN200810137379.5 discloses a kind of foldable inflating expansion solar cell paddles synchronous expansion mechanism; It adopts pneumatic actuation, and is higher to sealing requirements, has increased cost virtually; Can not automatic drawing back after inflating expanded; Need external force, and can only become in-line to launch, developed area is restricted.

The utility model content

In order to overcome existing development mechanism complex structure; Adopt the high deficiency of pneumatic actuation sealing requirements; The utility model aims to provide a kind of solar cell windsurfing synchronous expansion mechanism, and this development mechanism can freely launch and regain, and the synchronism can guarantee to launch the time.

To achieve these goals; The technical scheme that the utility model adopted is: said solar cell windsurfing synchronous expansion mechanism comprises fixed support and travel(l)ing rest; Its design feature is; Said support bracket fastened two ends are hinged with two second ends that launch arm respectively, and every second other end that launches arm all has second gear; The two ends of said travel(l)ing rest are hinged with two first ends that launch arm respectively, and every first other end that launches arm all has first gear; Said first gear and second gear formation gear pair that is meshing with each other; Said fixed support medium position and second launches the arm medium position and links to each other through a hydraulic pressure pull bar; Between the said gear pair of fixed support two ends one side, link to each other through a telescoping mechanism.

Further; The structure optimization of said telescoping mechanism does; The gear end that the said first expansion arm and second launches arm all has the gear axis hole; The bearing pin that can rotate relative to gear is housed in this gear axis hole, and the bearing pin that is contained on first gear is fixedly connected through the bearing pin connector with bearing pin on being contained in second gear, and two bearing pin connectors that are positioned at fixed support two ends one side are fixedly connected on the two ends of a loop bar respectively.

Above-mentioned first gear and second gear are 1/4th gears.

By said structure, synchronous expansion mechanism launches arm by two, two rotating pins, and a bearing pin connector, two 1/4th gears, fixed support, travel(l)ing rest, hydraulic pressure pull bar and loop bar are formed.

Operation principle: 1/4th gears are fixed together with the expansion arm; Two bearing pins launch arm with two and realize that with the bearing pin connector revolute is connected; Such two gears engaged together; One end of the second expansion arm links to each other with revolute with fixed support, and an end and the travel(l)ing rest of the first expansion arm link together, and the hydraulic pressure pull bar is connecting fixed support and second and launching arm.

During stretching, extension, oil pressure actuated hydraulic pressure pull bar promotes the second expansion arm and rotates around support bracket fastened rotating shaft, because the gears engaged effect; Second launches arm drives the first expansion arm rotation, and two expansion arms launch synchronously outside the moving that travel(l)ing rest is parallel; Loop bar stretches, and realizes stretching.

During contraction, oil pressure actuated hydraulic pressure pull bar pulling second launches arm and rotates around support bracket fastened rotating shaft, because the gears engaged effect; Second launches arm drives the first expansion arm rotation; What travel(l)ing rest was parallel moves inward, and loop bar shrinks, and final entire mechanism is punctured into the I font.

Compared with prior art, the beneficial effect of the utility model is: the utility model can be realized freely launching and regaining, and has guaranteed to launch and the synchronism when regaining; And the number of components that adopts is few, and developed area is big, and sealing etc. is not almost required, and reliability is high.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
