Embodiment Construction
[0044] The present invention will be further described below with reference to the accompanying drawings and specific examples. The advantages and features of the present invention will be more apparent from the following description and appended claims. It should be noted that the figures use a very simplified form and use non-precision ratios, only for convenience, and clarity to clarify the purposes of the present invention.
[0045] It should be noted that all directional instructions (such as above, lower, left, right, front, and post, ...) are only used in a particular attitude (as shown in the accompanying drawings). The relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication is also changed accordingly.
[0046] See Figure 1 to 11 The core of the present invention is to provide a sector solar wing repeatedly deployed collapsed locking mechanism, including a fixed cover 1, a drive device, a drive wheel 3, a ce...

The invention discloses a fan-shaped solar wing repeated unfolding and folding locking mechanism. The mechanism comprises a fixed cover plate, a driving device,a driving wheel, a center wheel, a belt, a rotating cover plate, a locking groove and a locking rod, wherein the driving device is fixedly arranged at a first end of the fixed cover plate and is provided with an output shaft; the driving wheel is arranged on the output shaft, and the driving device is used for driving the driving wheel to rotate; the center wheel is rotationally connected to a second end of the fixed cover plate, and a protruding part is arranged on the center wheel; the belt is connected with the driving wheel and the center wheel; a second end of the rotating cover plate is rotationally connected with a second end of the fixed cover plate through a rotating assembly, the second end of the rotating cover plate is provided with a groove part, and a fan-shaped solar wing is arranged between the rotating cover plate and the fixed cover plate; the locking groove rotating cover plate which is formed in an end face, facing the rotating cover plate, of the driving wheel, and an opening right opposite to the protruding part is formed in one side of the locking groove; and the locking rod is arranged at a first end of the rotating cover plate. The mechanism is compact in structure, small in size and light in weight, and functions of unfolding, folding and locking the fan-shaped solar wing can be reliably and repeatedly achieved.
Description
Technical field [0001] The invention belongs to the field of sun wing, in particular, to a sector sun wing repeatedly launching a collapse mechanism. Background technique [0002] The spacecraft mainly rely on the sun wings to provide electrical energy for the spacecraft during the long-term operation. The solar wing utilizes the upper battery pack to convert light energy into electric energy for spacecraft. [0003] The working mode of the solar wing is: When the spacecraft is launched, the solar wing is in the gathering state, and the volume occupied is reduced; it is necessary to reliably lock to withstand the vibration conditions of the rising section; after the spacecraft enters the rail, the sun wings are expanded, Power generation; unfolding status requires lock to improve the expansion base frequency. [0004] The fan-shaped sun wing has the characteristics of small gathering, simple structure and light weight. The two rigid cover, the plurality of struts, and the flexibl...
