Description

Technical Field

[0001] The present invention relates to the technical field of aerospace vehicles, and in particular to a variant nose cone with high load-bearing and locking capabilities based on redundant constraints. Background Art

[0002] An aerospace vehicle is one that can fly both in the atmosphere at altitudes below 100 km and in space above 100 km. From takeoff to flight in the atmosphere, through the atmosphere into space, and finally re-entering the atmosphere, the flight speed and atmospheric environment are constantly changing. To improve the flight capability and performance of an aerospace vehicle under varying conditions, it is necessary to adapt its structure to changing flight conditions to achieve the optimal flight state under those conditions. This is where the concept of a "morphing vehicle" comes in. The morphing nose cone is designed to address the problem of adapting to the various aerodynamic environments encountered by aerospace vehicles.

[0003] Existing variant nose cone designs lack locking capabilities and are not structurally designed for high load capacity. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] The following combination Figures 1 to 12 The variant nose cone 1000 with high load-bearing and locking capabilities based on redundant constraints according to an embodiment of the present invention is described.

[0040] like Figures 1 to 12 As shown, a variant nose cone 1000 with high load-bearing and locking capabilities based on redundant constraints according to an embodiment of the present invention (hereinafter referred to as the variant nose cone 1000 for convenience of description) includes a shell assembly 1, an active chain 2, a driven chain 3, a drive chain 4 and a locking chain 5.

[0041] The housing assembly 1 includes N housings 101 arranged sequentially from the back to the front, where N is a natural number greater than or equal to 4; that is, the number of the housings 101 is at least four, for example Figures 1 to 4 The variant nose cone in 1000 is six.

[0042] The active chain 2 is distributed on the left and right sides of the shell assembly 1 (that is, on the left and right sides of the bending deformation of the variant nose cone 1000) and is respectively connected to N shells 101, providing constraints for the deformation movement of the variant nose cone 1000; the driven chain 3 is distributed on the upper and lower sides of the shell assembly 1 (that is, on the upper and lower sides of the bending deformation of the variant nose cone 1000) and is respectively connected to N shells 101, providing constraints for the deformation movement of the variant nose cone 1000; thus, the deformation movement of the variant nose cone 1000 is constrained by the active chain 2 and the driven chain 3, and the movement range and movement trajectory of the variant nose cone 1000 are limited, so that the variant nose cone 1000 can be telescopically deformed and bent.

[0043] The drive chain 4 is distributed on the left and right sides from the first shell 101 to the second shell 101 and is connected to the first shell 101 and the second shell 101; the drive chain 4 provides the driving force required for the deformation of the variant head cone 1000, and is also a redundant constraint of the variant head cone 1000. The drive chain 4 is used to drive the telescopic deformation and bending deformation of the variant head cone 1000. Specifically, when the linear telescopic displacement of the drive chain 4 on the left and the drive chain 4 on the right remain the same, the telescopic deformation of the variant head cone 1000 can be achieved. When the linear telescopic displacement of the drive chain 4 on the left and the drive chain 4 on the right are different, the bending deformation of the variant head cone 1000 can be achieved.

[0044] The locking chain 5 is distributed within the first to third housings 101 and is connected to the first and third housings 101, respectively. When the drive chain 4 drives the variant nose cone 1000 to deform to a specified deformation state, the locking chain 5 is used to lock the variant nose cone 1000 and provide a load-bearing function. In other words, by providing the locking chain 5, when the variant nose cone 1000 deforms to different specified deformation states, the locking chain 5 locks the variant nose cone 1000 in the specified deformation state, which helps the variant nose cone 1000 reliably adapt to different environments.

[0045] According to the variant head cone 1000 with high load-bearing and locking capacity based on redundant constraints in an embodiment of the present invention, the active chain 2, the driven chain 3, the drive chain 4 and the locking chain 5 are connected in parallel to the inner side of the shell assembly 1. When working, the drive chain 4 on the left and the drive chain 4 on the right provide the driving force required for deformation, and drive the second shell 101 to move relative to the first shell 101 through their respective linear telescopic movements, thereby driving the active chain 2, the driven chain 3, the third shell 101 to the Nth shell 101 and the locking chain 5 to move, thereby realizing the deformation of the variant head cone 1000. At the same time, the active chain 2 on the left, the active chain 2 on the right, the driven chain 3 on the upper side and the driven chain 3 on the lower side can better limit the deformation movement range and The motion trajectory enables the variant head cone 1000 to be able to telescopically deform and bend; when the linear telescopic displacement of the drive chain 4 on the left and the drive chain 4 on the right remain the same, the telescopic deformation of the variant head cone 1000 can be achieved, and when the linear telescopic displacement of the drive chain 4 on the left and the drive chain 4 on the right are different, the bending deformation of the variant head cone 1000 can be achieved; when the variant head cone 1000 is deformed to different specified deformation states, the locking chain 5 locks the specified deformation state of the variant head cone 1000. At the same time, the drive chain 4 and the locking chain 5 provide redundant constraints for the variant head cone 1000, and the locking chain 5 also provides a load-bearing function for the variant head cone 1000, so that the overall load-bearing capacity of the variant head cone 1000 is effectively improved, which is beneficial for the variant head cone 1000 to reliably adapt to different environments.

[0046] In some embodiments, as Figure 4 、 Figures 8 to 10 As shown, the locking chain 5 includes a first carrier 502, a locking slot 503 and a locking rod 504; the two ends of the first carrier 502 are respectively ball-jointed with the first shell 101 and the third shell 101, and the first carrier 502 is retractable and can withstand the tension along the extension direction of the first carrier 502 (that is, the extension and contraction direction of the first carrier 502); one end of the locking slot 503 is fixed to one end of the first carrier 502, and one end of the locking rod 504 is fixed to the other end of the first carrier 502, and the locking slot 503 and the locking rod 504 are slidably fitted in the extension direction of the first carrier 502; when the drive chain 4 drives the variant head cone 1000 to deform to a specified deformation state, the locking slot 503 and the locking rod 504 are locked. Therefore, when the variant head cone 1000 is deformed to different specified deformation states, the locking chain 5 locks the specified deformation state of the variant head cone 1000 through the locking groove 503 and the locking rod 504, and provides a bearing function through the first bearing member 502, thereby sharing the load borne by the variant head cone 1000 as a whole, improving the bearing capacity of the variant head cone 1000, and thus helping the variant head cone 1000 to reliably adapt to different environments.

[0047] In some embodiments, the locking slot 503 is provided with pin holes 5031 distributed along the extension direction of the locking slot 503, and the locking rod 504 is provided with a pin 5041, which can pop out and retract; when the drive chain 4 drives the variant nose cone 1000 to deform to different specified deformation states, the pin 5041 pops out and inserts into the corresponding pin hole 5031. In this way, for different environments, the drive chain 4 can drive the variant nose cone 1000 to deform to different specified deformation states, and the pin 5041 on the locking rod 504 of the locking chain 5 pops out and inserts into the corresponding pin hole 5031 on the locking slot 503, so that the locking rod 504 and the locking slot 503 are fixed, thereby locking the different specified deformation states of the variant nose cone 1000. This is conducive to the variant nose cone 1000 being able to reliably adapt to different environments. It should be noted that when there is no need to lock the deformed state of the variant nose cone 1000, the pin 5041 can retract and disengage from the pin hole 5031, so that the locking rod 504 and the locking slot 503 can slide relative to each other.

[0048] In some embodiments, the locking rod 504 is slidably embedded in the locking slot 503, and the first carrier 502 passes through the locking rod 504 and the locking slot 503. Thus, the structure is compact and reliable.

[0049] In some embodiments, the locking lever 504 includes two sliding portions 5042 located on opposite sides of the first carrier 502, each of which is provided with a pin 5041. The locking slot 503 includes two side portions 5032 located on opposite sides of the first carrier 502, each of which is provided with a sliding slot, and the walls of the sliding slots are provided with a pin hole 5031. The two sliding portions 5042 of the locking lever 504 slidably engage with the two sliding slots of the locking slot 503. This results in a compact and reliable structure with an effective locking effect.

[0050] In some embodiments, the first bearing member 502 is a first gas spring, which is retractable and has a high bearing capacity.

[0051] In some embodiments, the locking chain 5 also includes two locking bases 501, and the two locking bases 501 are ball-jointed with the two ends of the first carrier 502. The two locking bases 501 are respectively fixed to the first shell 101 and the third shell 101, that is, the two ends of the first carrier 502 are ball-jointed with the first shell 101 and the third shell 101 through the two locking bases 501, and the locking chain 5 is easy to install.

[0052] In some embodiments, as Figure 4 、 Figure 8 and Figure 11As shown, the nose cone 1000 further includes a load-bearing chain 6, which is distributed inside the third shell 101 to the Nth shell 101 and is respectively connected to the third shell 101 and the Nth shell 101. The load-bearing chain 6 provides redundant constraints for the variant nose cone 1000, while further improving the load-bearing capacity of the variant nose cone 1000, thereby helping the variant nose cone 1000 to reliably adapt to different environments.

[0053] In some embodiments, the load-bearing chain 6 includes a second load-bearing member 602, the ends of which are respectively connected to the third shell 101 and the Nth shell 101 by ball joints. The second load-bearing member 602 is retractable and can withstand tension along the extension direction of the second load-bearing member 602. Thus, the load-bearing chain 6 provides redundant constraints for the variant nose cone 1000, and the second load-bearing member 602 further improves the load-bearing capacity of the variant nose cone 1000, thereby helping the variant nose cone 1000 to reliably adapt to different environments.

[0054] In some embodiments, the second bearing member 602 is a second gas spring, which is retractable and has a high bearing capacity.

[0055] In some embodiments, the load-bearing chain 6 also includes two load-bearing bases 601, and the two load-bearing bases 601 are ball-jointed with the two ends of the second load-bearing member 602. The two load-bearing bases 601 are respectively fixed to the third shell 101 and the Nth shell 101, that is, the two ends of the second load-bearing member 602 are ball-jointed with the third shell 101 and the Nth shell 101 through the two load-bearing bases 601, and the load-bearing chain 6 is easy to install.

[0056] In some embodiments, as Figure 4 and Figure 5 As shown, the active chain 2 includes N active bases 201 and N active links 202. The N active bases 201 are distributed sequentially from the back to the front and are correspondingly fixed to the N housings 101. The N active links 202 are hinged end-to-end from the back to the front. The first active base 201 is hinged to the rear end of the first active link 202. The second active base 201 to the N-1th active base 201 are hinged to the middle of the second active link 202 to the N-1th active link 202, respectively. The Nth active base 201 is hinged to the front end of the Nth active link 202. This active chain 2 has a simple structure and can effectively constrain the motion range and motion trajectory of the variant nose cone 1000.

[0057] In some embodiments, as Figure 4 and Figure 6As shown, the driven chain 3 includes N driven bases 301, N-1 driven first links 302, and N-1 driven second links 303. The N driven bases 301 are distributed sequentially from the back to the front and are respectively fixed to N housings 101. The first driven base 301 to the N-1 driven base 301 are respectively hinged to one end of the N-1 driven first links 302, and the second driven base 301 to the N-1 driven base 301 are respectively ball-jointed to one end of the N-1 driven second links 303. The other ends of the adjacent driven second links 303 are hinged to the other ends of the driven first links 302. The driven chain 3 has a simple structure and can effectively constrain the motion range and motion trajectory of the variant nose cone 1000.

[0058] In some embodiments, as Figure 4 and Figure 7 As shown, the drive chain 4 includes two drive bases 401 and a drive telescopic rod 402 hinged between the two drive bases 401. The two drive bases 401 are respectively fixed to the first shell 101 and the second shell 101. The drive chain 4 has a simple structure and can drive the deformation of the modified nose cone 1000 through its own linear telescopic motion. Preferably, the drive telescopic rod 402 is an electric push rod.

[0059] In some embodiments, as Figures 1 to 3 As shown, there are six housings 101, two active chains 2, two driven chains 3, two drive chains 4, two locking chains 5, and four load-bearing chains 6. The housings 101, active chains 2, two driven chains 3, two drive chains 4, two locking chains 5, and four load-bearing chains 6 may also be other reasonable numbers.
