[0054] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0055] As Figures 1 to 6 shown, an embodiment of the present invention provides a rocket auxiliary bundling mechanism, including:

[0056] a first support 1, a first adjusting wedge 21, a second adjusting wedge 22, and a second support 3;

[0057] wherein, a first end face of the first support 1 is fixedly connected to a core stage rocket 4, a first fixing plate 11 and a second fixing plate 12 are arranged on a second end face of the first support 1, and the first fixing plate 11 and the second fixing plate 12 are arranged opposite to each other;

[0058] both the first adjusting wedge 21 and the second adjusting wedge 22 are slidably connected to the second end face of the first support 1, and are both arranged between the first fixing plate 11 and the second fixing plate 12;

[0059] The first end face of the second support 3 is fixedly connected to the booster 5, and a first sliding part and a second sliding part are provided on the second end face of the second support 3;

[0060] The first ends of the first sliding part and the second sliding part are both fixedly connected to the second end face of the second support 3 and are oppositely arranged on the second end face of the second support 3. The second ends of the first sliding part and the second sliding part are both arranged between the first adjusting wedge 21 and the second adjusting wedge 22;

[0061] The first fixing plate 11 is provided with a first bolt hole. The first bolt 111 passes through the first bolt hole and contacts the first adjusting wedge 21, and pushes the first adjusting wedge 21 to press the first sliding part;

[0064] During the flight, when due to the vibration and moment of the core stage rocket engine, a displacement difference in the X-axis direction is generated between the core stage rocket 4 and the booster 5, the displacement difference generated by the vibration can be eliminated through the up and down relative sliding in the X-axis direction between the adjusting wedge and the sliding part, so as to realize the automatic adjustment function of the X-axis displacement difference during the flight; wherein, the X-axis direction is parallel to the direction of the core stage rocket 4, that is, the direction from the tail of the core stage rocket 4 to the head of the core stage rocket 4; the adjustment amount of the X-axis displacement difference is the difference between the length of the adjusting wedge and the length of the sliding part, that is Figure 5 the H in Figure 5 where X is the direction from the tail of the core stage rocket 4 to the head of the core stage rocket 4;

[0065] Meanwhile, since the adjusting wedge block and the sliding part are slidably connected, when the bundling link 7 is unlocked and released, under the self-weight of the booster 5, the sliding part can directly disengage from the clamping of the adjusting wedge block, enabling the sub-bundling mechanism to achieve the function of automatic disconnection.

[0079] The second cover plate 222 is provided with a sixth through hole corresponding to the second bolt hole.

[0080] In this embodiment, the first guiding rod 211 is used to support and guide the first adjusting wedge 21 to prevent the first adjusting wedge 21 from shifting during the sliding process; in a preferred solution, two first guiding rods 211 may be provided and are respectively located on both sides of the first bolt hole; the second guiding rod 221 is used to support and guide the second adjusting wedge 22 to prevent the second adjusting wedge 22 from shifting during the sliding process; in a preferred solution, two second guiding rods 221 may be provided and are respectively located on both sides of the second bolt hole; the first guiding rod 211 and the second guiding rod 221 are symmetrically arranged; the first cover plate 212 is used to fix the second end of the first guiding rod 211.

[0082] Wherein, the first end of the first fixed block 311 is fixed on the second end face of the second support 3, and at least one first circular groove is provided on the end face of the second end of the first fixed block 311;

[0083] The first end of the third guide rod 314 is fixed in the first circular groove, and the second end of the third guide rod 314 is fixedly connected to the first limiting plate 313;

[0084] The first movable block 312 is sleeved on the second end of the third guide rod 314 and is located between the first limiting plate 313 and the first rectangular spring 315;

[0085] The first movable block 312 is slidably connected to the third guide rod 314, and the side surface of the first movable block 312 is in contact connection with the first adjusting wedge 21.

[0086] In an optional embodiment of the present invention, the second sliding portion includes: a second fixed block 321, a second movable block 322, a second limiting plate 323, at least one fourth guide rod 324, and a second rectangular spring 325 sleeved on the first end of the fourth guide rod 324;

[0087] Wherein, the first end of the second fixed block 321 is fixed on the second end surface of the second support 3, and at least one second circular groove is provided on the end surface of the second end of the second fixed block 321;

[0088] The first end of the fourth guide rod 324 is fixed in the second circular groove, and the second end of the fourth guide rod 324 is fixedly connected to the second limiting plate 323;

[0089] The second movable block 322 is sleeved on the second end of the fourth guide rod 324 and is located between the second limiting plate 323 and the second rectangular spring 325;

[0090] The second movable block 322 is slidably connected to the fourth guide rod 324, and the side surface of the second movable block 322 is in contact connection with the second adjusting wedge 22.

[0091] In this embodiment, the first movable block 312 can slide on the third guide rod 314 by compressing the first rectangular spring 315; the second movable block 322 can slide on the fourth guide rod 324 by compressing the second rectangular spring 325; the first end of the third guide rod 314 is fixed in the first circular groove by at least one first hexagon socket head screw 61, and the second end of the third guide rod 314 is fixedly connected to the first limiting plate 313 by a first hexagon socket head shoulder screw 81; the first end of the fourth guide rod 324 is fixed in the second circular groove by at least one second hexagon socket head screw 62, and the second end of the fourth guide rod 324 is fixedly connected to the second limiting plate 323 by a second hexagon socket head shoulder screw 82; in a preferred solution, the number of the third guide rods 314 and the fourth guide rods 324 is 4 each.

[0092] In this embodiment, as Figure 7 shown, Figure 7 Y in represents the direction perpendicular to the booster 5 and the core stage rocket 4, that is, the direction in which the booster 5 approaches the core stage rocket 4; the structural design of the first sliding part and the second sliding part enables the rocket sub-bundling mechanism to have the function of automatically adjusting the displacement difference in the Y-axis direction (the Y-axis direction is the direction perpendicular to the booster 5 and the core stage rocket 4), that is, when the booster 5 approaches the core stage rocket 4, the first adjusting wedge 21 and the second adjusting wedge 22 will push the first movable block 312 and the second movable block 322, so that the first movable block 312 and the second movable block 322 compress the first rectangular spring 315 and the second rectangular spring 325, so that the first support 1 moves towards the second support 3, thereby eliminating the displacement difference generated when the booster 5 approaches the core stage rocket 4; similarly, when the booster 5 moves away from the core stage rocket 4, the compression amount of the first rectangular spring 315 and the second rectangular spring 325 can be restored by stretching, so as to eliminate the displacement difference generated when moving away; during installation, the first rectangular spring 315 and the second rectangular spring 325 need to be compressed to a certain extent to meet the stretching when the booster 5 moves away from the core stage rocket 4, and at the same time, after compression, the first rectangular spring 315 and the second rectangular spring 325 can also generate a pushing force during the separation of the booster 5 and the core stage rocket 4 to assist the separation of the booster 5.

[0093] In this embodiment, the adjustment amount of the displacement difference in the Y-axis direction is related to the heights of the first rectangular spring 315 and the second rectangular spring 325, that is, Figure 7 L in, so the adjustment amount of the displacement difference in the Y-axis direction can be set by selecting different specifications of the first rectangular spring 315 and the second rectangular spring 325.

[0094] In an alternative embodiment of the present invention, the contact surfaces of the first adjusting wedge block 21 and the first sliding part are both inclined surfaces;

[0095] The contact surfaces of the second adjusting wedge block 22 and the second sliding part are both inclined surfaces.

[0096] In an alternative embodiment of the present invention, the design that the length of the end face of the first sliding part in contact with the first adjusting wedge block 21 is greater than the length of the end face of the first adjusting wedge block 21 in contact with the first sliding part is to enable the first adjusting wedge block 21 to slide stably on the first sliding part, and at the same time increase the adjustment amount of the first adjusting wedge block 21 and the first sliding part in the X direction.

[0097] The design that the length of the end face of the second sliding part in contact with the second adjusting wedge block 22 is greater than the length of the end face of the second adjusting wedge block 22 in contact with the second sliding part is to enable the second adjusting wedge block 22 to slide stably on the second sliding part, and at the same time increase the adjustment amount of the second adjusting wedge block 22 and the second sliding part in the X direction.

[0098] In an alternative embodiment of the present invention, the first end face of the first support 1 is an arc structure. The first end face of the first support 1 is fixedly connected to the core stage rocket 4 through at least two third bolts 14. The arc structure design of the first end face of the first support 1 is to be able to connect more closely with the core stage rocket 4. The specific radian value of the arc structure on the first support 1 can be set according to the radian of the contact surface with the core stage rocket 4.

[0099] In an alternative embodiment of the present invention, the first end face of the second support 3 is an arc structure. The first end face of the second support 3 is fixedly connected to the booster 5 through at least three fourth bolts 31. The arc structure design of the first end face of the second support 3 is to be able to connect more closely with the booster 5. The specific radian value of the arc structure on the second support 3 can be set according to the radian of the contact surface with the booster 5.

[0100] The specific use process of the rocket secondary bundling mechanism described in this embodiment is as follows: First, fix the first fixing plate 11, the second fixing plate 12, the first adjusting wedge 21, and the second adjusting wedge 22 on the second end face of the first support 1 in sequence, and fixedly connect the first end face of the first support 1 with the core stage rocket 4. Then, fix the first sliding part and the second sliding part on the second end face of the second support 3, and fixedly connect the first end face of the second support 3 with the booster 5. Then, adjust the positions of the first sliding part and the second sliding part, and place the first sliding part and the second sliding part between the first adjusting wedge 21 and the second adjusting wedge 22. At the same time, compress the first rectangular spring 315 to a first preset value through the first movable block 312, and compress the second rectangular spring 325 to a second preset value through the second movable block 322. The first preset value is equal to the second preset value. Finally, push the first adjusting wedge 21 by rotating the first bolt 111. At the same time, push the second adjusting wedge 22 by rotating the second bolt 121, so that the first adjusting wedge 21 and the second adjusting wedge 22 clamp the first sliding part and the second sliding part.

[0101] During the flight, when the core stage rocket 4 and the booster 5 generate vibrations in the X-axis direction, the displacement difference generated by the vibration can be eliminated by the relative up-and-down sliding between the adjusting wedge and the sliding part. When the core stage rocket 4 and the booster 5 generate vibrations in the Y-axis direction, the displacement difference generated by the vibration in the Y-axis direction can be eliminated by compressing or releasing the spring. During the flight, when the booster 5 needs to separate from the core stage rocket 4, the bundling link 7 can be unlocked and released first. Then, under the self-gravity of the booster 5, the first sliding part and the second sliding part can directly break away from the clamping of the first adjusting wedge 21 and the second adjusting wedge 22, thereby realizing the automatic disconnection of the secondary bundling mechanism.

[0102] The rocket secondary bundling mechanism described in the present invention solves the problems of the traditional secondary bundling mechanism, such as complex structure, low safety, and inability to adjust the displacement difference generated axially between the booster and the core stage rocket during flight. It realizes the automatic adjustment function of the displacement difference generated axially between the booster and the core stage rocket during flight. At the same time, it improves the safety of the secondary bundling mechanism and also has the advantages of simple structure, small mass, and convenient installation.

[0103] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
