The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. It should be noted that the following embodiments may be referred to, referred to or combined with each other, and the description of the same terms, similar features, similar implementation steps and the like in different embodiments is not repeated.

Referring to fig. 1 to 5, an embodiment of the present application provides a separation apparatus 100, including: a first component 11 and a second component 12. The first module 11 includes a first body 111 and a support lug 112 connected, and the support lug 112 has a connection hole 112a. The second assembly 12 includes a second body 121, a first driving mechanism 122 and a pin body 123 connected in sequence, the second body 121 has a through hole 121a, and the first driving mechanism 122 is a pneumatic driving mechanism.

Referring to fig. 1 and 2, in the locked state, the pin body 123 is inserted into the connection hole 112a to limit the relative movement of the first component 11 and the second component 12 along the first direction X, and the support lug 112 is inserted into the through hole 121a to limit the relative movement of the first component 11 and the second component 12 along the second direction Y, where the first direction X intersects with the second direction Y, for example, the first direction X and the second direction Y may be perpendicular to each other.

The first direction X may be a direction perpendicular to the axial direction of the pin body 123, and the second direction Y may be a direction perpendicular to the axial direction of the lug 112.

Referring to fig. 3, the first driving mechanism 122 is used for driving the pin body 123 to exit the connecting hole 112a to switch the separating apparatus 100 to the unlocking state, in which the supporting lug 112 exits the through hole 121a to separate the first component 11 from the second component 12.

That is, in the locked state, the pin body 123 is inserted through the connection hole 112a, the lug 112 is inserted through the through hole 121a, and the relative movement of the first body 111 and the second body 121 is restricted from different directions, so that the two to-be-separated pieces fixed to the first body 111 and the second body 121, respectively, remain connected. When two to-be-separated pieces need to be separated, the first driving mechanism 122 drives the pin body 123 to exit the connecting hole 112a, and simultaneously, the support lug 112 exits the through hole 121a, so that the two to-be-separated pieces fixed with the first body 111 and the second body 121 are separated.

According to the separating device 100 provided by the embodiment of the application, automatic unlocking can be realized by utilizing the movement of each part driven by the first driving mechanism 122, initiating explosive devices such as gunpowder and the like do not need to be used, the impact force generated during separation is small, the possibility that the piece to be separated is damaged by the impact force of the separating device 100 can be reduced, and the working reliability of the piece to be separated is improved. Moreover, the structure of the separation device 100 can not be damaged, the separation device 100 can be repeatedly used, the cost of the ground test is reduced, and the accuracy of the ground test is improved. In addition, because the priming system does not need to use priming sytem such as gunpowder, the storage or transportation problem of energy sources such as gunpowder does not need to be considered, thereby being safer and more environment-friendly, and meanwhile, the subpackaging device does not need to contain the priming sytem and has lighter weight.

In this embodiment, the supporting lug 112 is telescopically arranged relative to the first body 111, and the first assembly 11 may further include a second driving mechanism (not shown) connected to the supporting lug 112, wherein the second driving mechanism is configured to drive the supporting lug 112 to extend into and retract out of the through hole 121a.

That is, in the locked state, the first body 111 is disposed outside the second body 121, the support lug 112 extends out of the first body 111 (for example, the second body 121 is tubular, and the support lug 112 moves towards the inside of the tubular second body 121) to be inserted into the through hole 121a of the second body 121, and the pin 123 is inserted into the connecting hole 112a of the support lug 112. When unlocking is required, the pin body 123 exits the connecting hole 112a of the lug 112, the lug 112 exits the first body 111 (for example, the second body 121 is tubular, and the lug 112 moves toward the outside of the tubular second body 121) to exit the through hole 121a of the second body 121, and the first body 111 and the second body 121 can move relatively (for example, the second body 121 is tubular, and the first body 111 and the second body 121 move relatively in the axial direction of the tubular second body 121) to separate.

It can be understood that the support lug 112 may be fixedly disposed with the first body 111, and the first body 111 may be movably disposed along the axial direction of the support lug 112, so as to drive the support lug 112 to extend into and retract out of the through hole 121a. For example, the first assembly 11 may further include a fixing member for fixing with a member to be separated, the fixing member is provided with a slide rail extending along the axial direction of the support lug 112, and the first body 111 is slidably disposed along the slide rail to drive the support lug 112 to extend into and retract out of the through hole 121a. Alternatively, the first body 111 is hinged to the fixing member (similar to a gripper), and the first body 111 rotates relative to the fixing member to drive the supporting lug 112 to extend into and retract out of the through hole 121a.

Referring to fig. 4 and 5, specifically, the second body 121 may include a sidewall surrounding the first driving mechanism, the first driving mechanism 122 is fixed on an inner surface of the sidewall, the number of the through holes 121a is at least two, and the at least two through holes 121a penetrate through the sidewall and surround the pin 123. The first body 111 is disposed on one side of the outer surface of the sidewall, the number of the support lugs 112 is at least two, and the at least two support lugs 112 and the at least two through holes 121a are disposed in a one-to-one correspondence manner.

The second body 121 may be tubular, or the second body 121 may include a plurality of first connecting portions arranged at intervals for connecting with the first member to be separated. Similarly, the first body 111 may be tubular, or the first body 111 may comprise a plurality of spaced apart second connection portions for connection to a second member to be separated. Alternatively, when the number of the through holes 121a and the lugs 112 is plural (three or more), the through holes 121a may be arranged at equal intervals in the circumferential direction of the second body 121, and correspondingly, the lugs 112 may be arranged at equal intervals in the circumferential direction of the first body 111. Of course, the number of the through holes 121a and the number of the support lugs 112 may be one, and is not limited herein.

With continued reference to fig. 4, 5, in this embodiment, the sidewall may comprise a first tubular structure for connection with the first member to be separated, each through-hole 121a extending through the first tubular structure. The first body 111 may include a plurality of second connection portions arranged at intervals for connecting with a second member to be separated, the support lugs 112 are arranged in one-to-one correspondence with the second connection portions, and the support lugs 112 are arranged on an inner surface of one side of the second connection portion close to the first tubular structure. That is to say, the second body 121 may be tubular, and the first body 111 may include a plurality of second connecting portions (similar to mechanical claws) arranged at intervals for connecting with the second member to be separated, and at this time, on the premise of ensuring the structural strength, the convenience of separating the first body 111 from the second body 121 is improved, and at the same time, the risk of difficulty in successful separation due to deformation of the first body 111 and the second body 121 is reduced.

In another possible embodiment, the side wall of the second body 121 may comprise a first tubular structure for connection with the first piece to be separated, each through hole 121a extending through the first tubular structure. The first body 111 comprises a second tubular structure for connection with a second member to be separated, and each lug 112 is provided on an inner wall surface of the second tubular structure. That is to say, the second body 121 and the first body 111 are both tubular structures, and the structural strength is high, so that the connection of the two members to be separated in the locked state is more reliable.

Alternatively, referring to fig. 5, at least two through holes 121a are arranged alternately in the axial direction of the first tubular structure, i.e. at least two through holes 121a are on different circumferences of the first tubular structure. Compared with the situation that all the through holes 121a are arranged on the same circumference of the first tubular structure, the structural strength of the first tubular structure can be improved and the first tubular structure is prevented from being broken or deformed at the position where the through holes 121a are arranged by staggering at least two through holes 121a in the axial direction of the first tubular structure.

Further, the number of the pin bodies 123 may be smaller than the number of the support lugs 112, and when the first component 11 is locked with the second component 12, at least a part of the pin bodies 123 are inserted into the connection holes 112a of at least two support lugs 112. That is, part or all of the support lugs 112 share one pin body 123, that is, there is one pin body 123 simultaneously inserted into the connection holes 112a of two or more support lugs 112, so that the number of the first driving mechanisms 122 and the number of the pin bodies 123 can be reduced, thereby reducing the cost. It should be noted that the number of the pin bodies 123 may be equal to the number of the support lugs 112, and in this case, one pin body 123 is inserted into the connection hole 112a of one support lug 112.

Of course, the at least two through holes 121a may also be sequentially disposed along the same circumference of the first tubular structure, at this time, the support lugs 112 are axially aligned with each other in the first tubular structure, and in order to avoid interference of the support lugs 112, the number of the pin bodies 123 needs to be equal to the number of the support lugs 112, that is, one pin body 123 is inserted into the connecting hole 112a of one support lug 112.

In this embodiment, the first driving mechanism 122 may include a piston cylinder 122a connected to the pin body 123, and an air supply device 122b communicated with the piston cylinder 122a, wherein the air supply device 122b is configured to supply air to the piston cylinder 122a to drive the piston cylinder 122a to perform a piston motion so as to drive the pin body 123 to perform a motion. That is, the separating device 100 in this embodiment is a pneumatic separating device 100, and a gas with a designed pressure is injected into one side of the piston in the piston cylinder 122a, so as to push the piston to drive the pin 123 to move.

Specifically, a piston 122c connected to the pin body 123 is provided in the piston cylinder 122a, and the piston 122c divides an inner space of the piston cylinder 122a into the first space 20 and the second space 30. In this embodiment, the first driving mechanism 122 may further include a direction changing part 122d, one end of the direction changing part 122d is communicated with the gas transmission end of the gas supply device 122b, and the other end of the direction changing part 122d is alternatively communicated with the first space 20 and the second space 30. That is, each piston cylinder 122a corresponds to one air supply device 122b (which may be a high-pressure air cylinder), the piston moving direction is changed by the reversing component 122d, and the extending and retracting of the pin body 123 are completed by time division multiplexing by using one air supply device 122b, so that the equipment cost can be reduced.

For example, when the reversing component 122d is in the first state, the reversing component 122d conducts the gas supply device 122b and the first space 20, the gas supply device 122b injects gas with a designed pressure into the first space 20, so that the gas pressure in the first space 20 is increased, and the piston moves towards the second space 30 side to drive the pin 123 to extend into the connecting hole 112a. When the reversing part 122d is in the second state, the reversing part 122d conducts the gas supply device 122b and the second space 30, the gas supply device 122b injects gas with designed pressure into the second space 30, so that the gas pressure in the second space 30 is increased, the piston moves towards one side of the first space 20, and the pin body 123 is driven to retract out of the connecting hole 112a.

Alternatively, the first driving mechanism 122 may further include a pressure reducing valve 122e, one end of the pressure reducing valve 122e being communicated with the air inlet of the direction changing part 122d, and the other end being communicated with the air supply device 122 b. The gas transmission end of the gas supply device 122b can also be provided with a switch 122f, and the switch 122f is used for controlling the start and stop of the gas supply device 122 b.

The reversing component 122d may include a reversing solenoid valve, and a control circuit 122g connected to the reversing solenoid valve, wherein the control circuit 122g is configured to control the reversing solenoid valve to alternatively communicate with the first space and the second space. The control circuit 122g may be implemented by an MCU microcontroller.

In another possible embodiment, the air supply device 122b may include a first air supply device and a second air supply device. The first gas supply device is communicated with the first space 20 and is used for injecting gas with a first design pressure into the first space 20, so that the gas pressure in the first space 20 is increased, and the piston moves towards one side of the second space 30 to drive the pin body 123 to extend into the connecting hole 112a. The second gas supply device is communicated with the second space 30, and is used for injecting gas with a second design pressure into the second space 30, so that the gas pressure in the second space 30 is increased, and the piston moves towards one side of the first space 20 to drive the pin body 123 to retract out of the connecting hole 112a. The first design pressure and the second design pressure may be equal or different, and are not limited herein.

Similarly, the second driving mechanism may include a piston cylinder 122a connected to the support lug 112, and a gas supply device 122b communicated with the piston cylinder 122a, wherein the gas supply device 122b is used for supplying gas to the piston cylinder 122a to drive the piston of the piston cylinder 122a to move so as to drive the support lug 112 to move. The second driving mechanism is similar to the first driving mechanism 122 in structure, and is not described herein again.

Alternatively, the material used for the separation device 100 may be machined from an aluminum alloy, which is lighter in weight than the pyrotechnic separation device 100.

In practical applications, as shown in fig. 6, the separation apparatus 100 can be used in combination of multiple sets as required. Alternatively, each separation apparatus 100 may share the pressure reducing valve 122e, that is, the plurality of air supply devices 122b communicate with the plurality of switches 122f in one-to-one correspondence, the air outlets of the plurality of switches 122f are merged to the air inlet of the same pressure reducing valve 122e, the air outlet of the pressure reducing valve 122e communicates with the air inlets of the plurality of direction changing parts 122d, the plurality of direction changing parts 122d communicate with the plurality of piston cylinders 122a in one-to-one correspondence, and each direction changing part 122d is connected to the control circuit 122 g. Of course, the air outlets of the switches 122f may also be communicated with the air inlets of the pressure reducing valves 122e in a one-to-one correspondence, which is not limited herein.

Based on the same inventive concept, the embodiment of the application provides a carrier rocket, which comprises: any of the separation devices as provided in the previous embodiments.
