Description

Technical Field

[0001] The utility model relates to the technical field of rigid frames, and more specifically to a grid-shaped rigid frame. Background Art

[0002] The basic principle of solar panels is to use the photoelectric effect of silicon and certain metals to convert solar energy into electrical energy, which is then stored in batteries to provide electricity for satellites, spacecraft, and electric vehicles. In order to prevent the solar panels from being damaged before they are deployed, rigid polyimide foam is required to protect them before deployment, and a grid-like rigid frame is required to install the rigid polyimide foam.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A grid-shaped rigid frame includes a connecting member 1, wherein the side walls of the connecting member 1 are provided with a card slot 2, a connecting rod 3 is fixed in the card slot 2, and a clamping assembly 4 is fixed on all sides of the top of the connecting member 1. The clamping assembly 4 includes a moving rod 401 that is slidably connected to the top of the connecting member 1, a disc 402 is fixed on the top of the moving rod 401, a handle 403 is fixed on the top of the disc 402, and a pressure plate 404 is fixed on the bottom of the moving rod 401. A cavity 406 is provided inside the connecting member 1, a moving plate 405 is fixed on the circumferential outer wall of the moving rod 401, and a spring 407 is fixed on the top of the moving plate 405 that is sleeved on the circumferential outer wall of the moving rod 401. A limiting assembly 5 is fixed on the top of the connecting rod 3, a hole 6 is provided in the middle of the top of the connecting member 1, and a double-layer compressor 7 is installed on the top of the hole 6. The double-layer compressor 7 is electrically connected to an external power supply. In the present invention, the staff pulls the handle 403 to drive the movable rod 401 to move upward, inserts the connecting rod 3 into the slot 2, releases the handle 403, and the rebound force of the spring 407 drives the movable plate 405 to move downward, so that the movable rod 401 drives the pressure plate 404 downward to press against the connecting rod 3, making the connection between the connecting part 1 and the connecting rod 3 more stable, thereby achieving a good compression and protection effect on the solar wing, and the upper and lower foam plates and the flexible solar wing in the folded state in the middle are completely compressed through the double-layer compressor 7 on the top of the hole 6.

[0029] Specifically, the limiting assembly 5 includes a fixed block 501, with multiple screw holes 502 defined in the top of the fixed block 501. Pins 503 are fixed to both sidewalls of the fixed block 501. A rotating frame 504 is rotatably connected to the outer circumference of the pins 503. A limiting plate 505 is fixed to the top of the rotating frame 504. The fixed block 501 is installed by screwing bolts into the screw holes 502. After the connecting rod 3 and the rigid polyimide foam are glued together, the rotating frame 504 is manually flipped over by a worker so that the limiting plate 505 abuts the top of the rigid polyimide foam, further stabilizing the connection between the connecting rod 3 and the foam board.

[0030] Furthermore, a pad 408 is fixedly provided at the bottom of the pressing plate 404, and the material of the pad 408 is vulcanized rubber. The pad 408 made of vulcanized rubber prevents damage to the connecting rod 3.

[0031] It is worth noting that the material of the connecting member 1 is aluminum and the material of the connecting rod 3 is carbon fiber. The aluminum connecting member 1 increases the hardness and the carbon fiber connecting rod 3 reduces the weight, which facilitates the use of the grid-like rigid frame.

[0032] It is noteworthy that a plurality of fixing plates 8 are fixed to the bottom of the side wall of the connecting rod 3, and the limiting plate 505 is fitted with the connecting rod 3. The position of the rigid polyimide foam is limited by the fixing plate 8 to prevent tilting during gluing.

[0033] In addition, the side walls of the connecting rod 3 are provided with overflowing glue grooves 9, and the top of the connecting rod 3 is provided with multiple ventilation holes 10. The overflowing glue grooves 9 prevent the glue from overflowing when the connecting rod 3 and the hard polyimide foam are glued together, which affects the appearance. The ventilation holes 10 accelerate air circulation, which facilitates faster solidification of the glue.

[0034] In addition, the circuits, electronic components, and modules involved in this utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the internal structure and method.

[0035] The device or equipment models involved in this article are as follows:

[0036] The model of the double-layer compactor 7 can be: FLLM-2C.

[0037] Working principle: When the device is required to be used as a grid-like rigid frame, the staff pulls the handle 403 to drive the moving rod 401 to move upward, inserts the connecting rod 3 into the slot 2, releases the handle 403, and the rebound force of the spring 407 drives the moving plate 405 to move downward, so that the moving rod 401 drives the pressure plate 404 downward to press against the connecting rod 3. The vulcanized rubber pad 408 is used to prevent damage to the connecting rod 3, making the connection between the connector 1 and the connecting rod 3 more stable, thereby achieving a good compression protection effect on the solar wing, and the upper and lower foam plates are pressed together through the double-layer compressor 7 at the top of the hole 6. The flexible solar wing in the middle folded state is completely pressed together, and the fixing block 501 is installed by screwing the bolt into the screw hole 502. After the connecting rod 3 and the hard polyimide foam are glued together, the staff manually flips the rotating frame 504 so that the limit plate 505 abuts against the top of the hard polyimide foam, which makes the connection between the connecting rod 3 and the foam board more stable. The position of the hard polyimide foam is limited by the fixing plate 8 to prevent it from tilting during gluing. The overflow glue groove 9 prevents glue from overflowing when the connecting rod 3 and the hard polyimide foam are glued together, which affects the appearance. The air circulation is accelerated through the air vent 10 to make the glue solidify faster.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
