Description

Technical Field

[0001] This invention belongs to the field of spacecraft solar panel mechanisms and relates to a two-section pop-out multi-panel separation locking and release device suitable for annular solar panels. Background Technology

[0002] Solar panels are crucial energy harvesting components for spacecraft, and their deployment and retraction reliability directly impacts the spacecraft's energy supply and normal operation. The deployment process of a ring-shaped solar panel generally consists of four stages: the retracted state, the deployment of the solar panel itself, the deployment of the first fold panel, and the deployment of the second fold panel. After the solar panel is deployed and locked, it operates normally to harvest solar energy.

[0003] Compared to ordinary rigid solar panels, annular solar panels have a smaller folded volume and a higher unfolding-to-fold ratio. Compared to circular solar panels, the annular solar panel's panels fold again, further reducing the folded volume. A challenge arises: multiple inner and outer panels of the annular solar panel need to be locked simultaneously, but the space between the panels is narrow, limiting the installation of multiple clamping seats and confining space. A locking mechanism is needed to achieve the simultaneous locking of multiple panels, presenting significant technical difficulties and design challenges.

[0004] The annular solar panel's enclosure mainly consists of an inner panel (movable and fixed) and an outer panel (movable and fixed). In the retracted state, the inner panel folds and closes to the outer panel, leaving a relatively narrow space between them. Under current design constraints, a two-section pop-out multi-panel separation, locking, and release device was designed and installed in the narrow space between the inner and outer panels (the gap between the panels is only 80mm).

[0005] Existing solar panel locking and release devices are all located in the center of the box panel structure, and the separation method is perpendicular to the box panel. They cannot achieve the locking and release function of locking multiple boxes at a single point and releasing multiple boxes in all directions. Summary of the Invention

[0006] The technical problem solved by this invention is to overcome the shortcomings of the prior art and propose a two-section pop-out multi-panel separation locking and release device suitable for annular solar panels. This device enables the annular solar panel to complete the locking and release function of multiple panels in all directions with a single pressing point, thereby improving the reliability of locking and releasing and increasing the space utilization rate of the pressing point.

[0007] The solution of the present invention is:

[0011] In the above-mentioned two-section pop-out multi-panel separation locking and release device applicable to the annular solar panel, the horizontal end of the fixed panel bracket is inclined upward and protrudes; the protrusions of the two fixed panel brackets form an upward angle structure, which is pressed by the conical frame at the bottom of the two-section separation limiting cover to achieve locking of the two fixed panel brackets.

[0012] In the aforementioned two-section pop-out multi-panel separation locking and release device applicable to the annular solar panel, the top of the clamping rod assembly is provided with a circumferential flange structure; the top of the clamping rod spring contacts the lower surface of the flange of the clamping rod assembly; and the bottom of the clamping rod spring contacts the upper surface of the two-section separation limiting cover.

[0015] Two fixed box plate brackets are connected to the fixed plates of the inner box plate and the outer box plate of the outer annular solar wing respectively by bolts; two movable box plate brackets are connected to the movable plates of the inner box plate and the outer box plate of the outer annular solar wing respectively by bolts.

[0016] In the above-mentioned two-section pop-out multi-box plate separation locking and release device applicable to the annular solar fin, when the outer annular solar fin is retracted, the clamping rod assembly, under the action of the locking torque, sequentially presses the clamping rod spring, the two-section separation spring, the two-section separation limit cover, the fixed box plate bracket and the movable box plate bracket onto the clamping seat from top to bottom; the pyrotechnic separation nut assembly locks the thread at the end of the clamping rod assembly;

[0017] With the outer annular solar fin deployed, the pyrotechnic separation nut assembly releases the end of the clamping rod assembly; the clamping rod spring and the second-stage separation spring release and unfold; the clamping rod assembly pops out under the action of the clamping rod spring and the second-stage separation spring and stays on the buffer core assembly; the second-stage separation limit cover pops up under the action of the second-stage separation spring, releasing the fixed box plate bracket and the movable box plate bracket; the fixed plate of the inner box plate of the outer annular solar fin, the movable plate of the inner box plate of the outer annular solar fin, the fixed plate of the outer box plate of the outer annular solar fin, and the movable plate of the outer box plate of the outer annular solar fin are all released from constraints, and the locking and releasing device is fully unlocked.

As the solar array body deploys, the pyrotechnic separation nut assembly in the clamping seat releases the end of the clamping rod assembly, and the clamping rod spring releases its elastic potential energy, popping the clamping rod assembly out. The second-section separation spring releases its elastic potential energy, popping out the second-section separation limit cover. The buffer core assembly provides buffering and limiting for the clamping rod assembly. The second-section separation support provides buffering and limiting for the second-section separation limit cover. A hard limit is provided; the fixed plate of the inner box panel of the outer annular solar wing, the movable plate of the inner box panel of the outer annular solar wing, the fixed plate of the outer box panel of the outer annular solar wing, and the movable plate of the outer box panel of the outer annular solar wing are attached together; the box panel embedded parts, the fixed box panel brackets, and the movable box panel brackets leave the surface of the outer planet as a whole with the outer annular solar wing; the clamping rod of the two-section pop-out multi-box panel separation locking release device is released by the pyrotechnic separation nut, and the outer annular solar wing is separated from the side wall of the outer planet as a whole; the locking release device follows the inner and outer box panels to separate from the clamping seat, and the inner and outer box panels are no longer bound by the clamping rod and are in a free state.

[0019] In the aforementioned two-section pop-out multi-panel separation locking and release device applicable to the annular solar fin, when the outer annular solar fin unfolds with one fold of the pan, the inner and outer pans are separated, and the two-section pop-out multi-panel separation locking and release device separates into three parts: the inner pan, the outer pan, and the pyrotechnic component. The inner pan includes a pan embedding part, a fixed pan bracket, and a movable pan bracket; the outer pan includes a pan embedding part, a fixed pan bracket, and a movable pan bracket; the pyrotechnic component includes a clamping seat and a pyrotechnic separation nut assembly. As the outer annular solar fin unfolds with one fold, the inner and outer pans separate; the clamping rod spring, clamping rod assembly, two-section separation limit cover, buffer core assembly, two-section separation spring, and two-section separation support separate along with the outer pan.

[0020] In the above-mentioned two-section pop-out multi-box panel separation locking and release device applicable to the annular solar wing, when the outer annular solar wing's two-fold wing surface is unfolded, in the state of the movable plate and the fixed plate being separated, the two-section pop-out multi-box panel separation locking and release device is separated into five parts, namely the fixed inner box panel part, the movable inner box panel part, the fixed outer box panel part, the movable outer box panel part, and the pyrotechnic part.

[0022] As the outer annular solar panel unfolds, the fixed and movable ends of the inner box panel separate with the wing surface, and the fixed and movable ends of the outer box panel separate with the wing surface; the clamping rod spring, clamping rod assembly, two-stage separation limit cover, buffer core assembly, two-stage separation spring and two-stage separation support move with the outer box panel fixed plate, and the two-stage pop-up multi-box panel separation locking and release device completely separates.

[0023] The advantages of this invention compared to the prior art are:

[0024] (1) This invention innovatively proposes a two-stage pop-out type multi-box plate separation locking and release device. Based on the existing clamping rod spring design, two separation springs are added. Multiple boxes are locked at the same time through a single clamping point, and multiple boxes can be released in all directions. It has the advantages of reliable locking and high space utilization.

[0025] (2) This invention solves the problem of narrow space between the inner and outer boxes of the annular solar panel and the need for multiple boxes to be pressed together, ensuring that pressing multiple boxes at a single point does not hinder the realization of the lateral separation function of the boxes.

[0026] (3) The present invention reduces the number of pressing points of the annular solar panel, reduces the weight of the pressing device, and improves the stability and reliability of the pressing device. Attached Figure Description

[0042] like Figure 4 As shown, the deployment process of the annular solar array is generally divided into four stages, including the folded state, the deployment of the solar array body, the deployment of the first fold box plate, and the deployment of the second fold wing surface. After the solar array is deployed and locked, it can work normally to obtain solar energy.

[0043] like Figure 5 As shown, the box panel of the annular solar panel is mainly composed of an inner box panel that is movable and fixed, and an outer box panel that is movable and fixed. In the retracted state, the inner box panel folds and closes to the outer box panel, and there is a relatively narrow space between the inner and outer box panels. Two pop-out multi-box panel separation locking and release devices are installed between the inner and outer box panels.

[0044] like Figure 6a As shown, when the external annular solar fin is retracted, the clamping rod assembly 4, under the action of the locking torque, sequentially presses the clamping rod spring 3, the two-stage separation spring 10, the two-stage separation limit cover 5, the fixed box plate bracket 2, and the movable box plate bracket 7 onto the clamping seat 9 from top to bottom; the pyrotechnic separation nut assembly 8 locks the threaded end of the clamping rod assembly 4.

[0045] When the external annular solar wing is deployed, the pyrotechnic separation nut assembly 8 releases the end of the clamping rod assembly 4; the clamping rod spring 3 and the two-stage separation spring 10 are released and deployed; the clamping rod assembly 4 pops out under the action of the clamping rod spring 3 and the two-stage separation spring 10 and stays on the buffer core assembly 6; the two-stage separation limit cover 5 pops up under the action of the two-stage separation spring 10, releasing the fixed box plate bracket 2 and the movable box plate bracket 7; the fixed plate of the inner box plate of the external annular solar wing, the movable plate of the inner box plate of the external annular solar wing, the fixed plate of the outer box plate of the external annular solar wing, and the movable plate of the outer box plate of the external annular solar wing are all released from constraints, and the locking and releasing device is fully unlocked.

[0046] like Figure 6b As shown, when the solar wing body deploys, in the separated state of the celestial body, the two-section pop-out multi-box plate separation locking and release device separates into two parts, namely the box plate part and the pyrotechnic part; as the solar wing body deploys, the pyrotechnic separation nut assembly 8 in the clamping seat 9 releases the end of the clamping rod assembly 4, the clamping rod spring 3 releases elastic potential energy, and pops the clamping rod assembly 4 out; the second-section separation spring 10 releases elastic potential energy, and pops the second-section separation limiting cover 5 out; the buffer core assembly 6 provides buffer limiting for the clamping rod assembly 4; the second-section separation support 11 provides hard limiting for the second-section separation limiting cover 5; external The fixed plate of the inner box panel of the annular solar wing, the movable plate of the inner box panel of the outer annular solar wing, the fixed plate of the outer box panel of the outer annular solar wing, and the movable plate of the outer box panel of the outer annular solar wing are attached together; the box panel embedded part 1, the fixed box panel bracket 2, and the movable box panel bracket 7 leave the surface of the outer planet as a whole with the outer annular solar wing; the clamping rod of the two-section pop-out multi-box panel separation locking release device is released by the pyrotechnic separation nut, and the outer annular solar wing is separated from the side wall of the outer planet as a whole; the locking release device follows the inner and outer box panels to separate from the clamping seat 9 as a whole, and the inner and outer box panels are no longer bound by the clamping rod and are in a free state.

[0047] like Figure 6c As shown, when the outer annular solar panel unfolds, the inner and outer panels are separated, and the two-section pop-out multi-panel separation locking and release device separates into three parts: the inner panel part, the outer panel part, and the pyrotechnic part. The inner panel part includes a panel embedded part 1, a fixed panel bracket 2, and a movable panel bracket 7. The outer panel part includes a panel embedded part 1, a fixed panel bracket 2, and a movable panel bracket 7. The pyrotechnic part includes a clamping seat 9 and a pyrotechnic separation nut assembly 8. As the outer annular solar panel unfolds, the inner and outer panels separate. The clamping rod spring 3, the clamping rod assembly 4, the two-section separation limit cover 5, the buffer core assembly 6, the two-section separation spring 10, and the two-section separation support 11 separate along with the outer panel.

[0048] like Figure 6dAs shown, when the outer annular solar panel's two-fold wing surface unfolds, in the separated state of the movable and fixed plates, the two-section pop-out multi-box plate separation and locking release device separates into five parts: the fixed inner box plate part, the movable inner box plate part, the fixed outer box plate part, the movable outer box plate part, and the pyrotechnic part. The fixed inner box plate part includes a box plate embedded part 1 and a fixed box plate bracket 2; the movable inner box plate part includes a box plate embedded part 1 and a movable box plate bracket 7; the fixed outer box plate part includes a box plate embedded part 1 and a fixed box plate bracket 2; the movable outer box plate part includes a box plate embedded part 1 and a movable box plate bracket 7; the pyrotechnic part includes a clamping seat 9 and a pyrotechnic separation nut assembly 8.

[0050] When the two-section pop-out multi-panel separation locking and release device is released from the pressed state, the movable panel (inner and outer) and the fixed panel (inner and outer) separate. The locking and release device completely separates along with the wing surface. The locking and release process is matched with each stage of the annular solar wing deployment process, so that the annular solar wing can complete the multi-panel locking and release function in all directions with a single pressing point.

[0051] This invention innovatively proposes a two-stage pop-out multi-panel separation locking and release device. Based on the existing clamping rod spring design, two separation springs are added. Multiple panels can be locked simultaneously through a single clamping point, and multiple panels can be released in all directions. It has the advantages of reliable locking and high space utilization.

[0052] This invention solves the problem of limited space between the inner and outer panels of the annular solar array, which necessitates the clamping of multiple panels, ensuring that single-point clamping of multiple panels does not hinder the lateral separation function of the panels. This invention reduces the number of clamping points on the annular solar array, lightens the weight of the clamping device, and improves the stability and reliability of the clamping device.
