Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the invention. In the present invention, unless otherwise indicated, terms of orientation such as "upper", "lower", "left", "right", "front", "rear" are generally used to refer to the directions of the upper, lower, left and right sides of the device in actual use or operation, and are specifically shown in the drawings.
It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present invention. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.
The invention provides a docking structure of a space telescope, in particular to a docking structure for a space telescope and a ground simulation adjustment system, which are described in detail below.
Referring to fig. 1, there are shown two identical sub-mirror modules 10 of a space telescope, each sub-mirror module 10 comprising a truss 101, a mirror 102 and an adjusting device 103. Truss 101 is a hollow structure, and adjusting device 103 is accommodated in truss 101, truss 101 is preferably a hexagonal prism truss, and is used for connecting truss 101 and mirror 102. The adjusting device 103 can adjust the position accuracy and the posture of the mirror surface 102 relative to the truss 101, and further adjust the angle of the mirror surface 102.
For ease of illustration, on two identical sub-mirror modules for connection with loose ions, the interface on one sub-mirror module becomes the first interface and the interface on the other sub-mirror module is referred to as the second interface. While the truss 101 of each sub-mirror module 10 is provided with at least one interface, which may be an active interface 1 or a passive interface 2. Of course, it is preferable that at least one pair of the active interface 1 and the passive interface 2 is provided, more preferably 3 pairs are provided, and the active interface 1 and the passive interface 2 are alternately provided. The two sub-mirror modules 10 are connected via an active interface 1 and/or a passive interface 2. The interface of the two sub-mirror modules 10 forms a sub-mirror module 10 docking structure of the space telescope, and it can be understood that the interface of the active interface 1 of one sub-mirror module 10 and the passive interface 2 of the other sub-mirror module 10 form a sub-mirror module 10 docking structure of the space telescope, the interface of the active interface 1 of one sub-mirror module 10 and the active interface 1 of the other sub-mirror module 10 form a sub-mirror module 10 docking structure of the space telescope, and the interface of the passive interface 2 of one sub-mirror module 10 and the active interface 1 of the other sub-mirror module 10 form a sub-mirror module 10 docking structure of the space telescope.
That is, the docking structure of the space telescope is composed of two interfaces separately arranged on the two sub-mirrors, one interface must be an active interface 1, and the other interface may be an active interface 1 or a passive interface 2. That is, the docking structure for the space telescope includes a first interface disposed on one sub-mirror module and a second interface disposed on the other sub-mirror module, wherein the first interface must be an active interface 1, and the second interface may be an active interface 1 or a passive interface 2.
It will also be appreciated that at least two interfaces are provided on the truss 101 of each sub-mirror, with the two interfaces preferably being one active interface 1 and one passive interface 2. The advantage of this arrangement is that, because the space telescope is formed by a plurality of sub-mirrors in a butt joint way, when the space telescope is assembled, a control device is needed, for example, a mechanical arm (not shown in the figure) grabs one interface to be in butt joint with another interface, at the moment, the upper end of the mechanical arm is also provided with an active interface, and the mechanical arm can be freely connected and loosened with any truss through the active interface at the end, so that the target sub-mirror is driven to move to a preset position.
For the scheme that the mechanical arm and the sub-mirror are matched to drive the mechanical arm and the sub-mirror to a preset position, a plurality of modes exist in the existing mode, for example, the scheme that the mechanical arm drives the sub-mirror to move to the preset position is thoroughly disclosed in a modular optical mirror surface ground simulation adjustment system and method with the application number of CN202311639651.0, and is not repeated here.
It will be appreciated, therefore, that in the case of the docking structure of a space telescope according to the application, the two interfaces may be provided not only on the two sub-mirror modules, but also on the control device of the space telescope and on the sub-mirror module, respectively. The operating device is used for being selectively connected and disconnected with the sub-mirror module so as to drive the sub-mirror module to move to a preset position. When one interface is arranged on the control device and the other interface is arranged on the sub-mirror module, the control device is preferably provided with a first interface, the sub-mirror module is provided with a second interface, and of course, the control device can be provided with the second interface, and the sub-mirror module is provided with the first interface.
That is, the docking structure for a space telescope provided by the application comprises a first interface arranged on a first piece and a second interface arranged on a second piece, wherein the first interface is an active interface 1, and the second interface is an active interface 1 or a passive interface 2. The first piece can be a sub-mirror module or a control device; similarly, the second piece may be a sub-mirror module or an actuator, but at most only one of the first piece and the second piece is an actuator, and at least one of the first piece and the second piece is a sub-mirror module.
Referring to fig. 2-9, a docking structure of a space telescope is provided, which is composed of an active interface 1 and a passive interface 2.
Referring to fig. 2, the active interface 1 includes a docking housing 3, an active locking module 4, an electrical connection module 5, an active chassis post, and a driving device 7.

The driving device 7 is in transmission connection with the active locking module 4 and is used for driving the active locking module 4 to move so as to realize locking of the active interface 1 and the passive interface 2. The drive means 7 comprise a motor 71 and a motor gland 72. The motor sealing sleeve 72 is fixedly arranged on one side of the driving chassis 6 away from the passive interface 2 in a sealing way, and the motor 71 is accommodated in a cavity formed by the motor sealing sleeve 72 and the driving chassis 6. The output end of the motor 71 passes through the active chassis 6 and is in transmission connection with the active locking module 4, which will be described in detail later.
Correspondingly, the passive interface 2 comprises a passive latch hook 21, a passive chassis column 22, and a docking shell 3 and an electrical connection module 5 which have the same structure as the active interface 1. The passive latch hook 21, the electrical connection module 5 and the docking shell 3 of the passive interface 2 are fixedly connected to the passive chassis column 22. The butt joint shell 3 of the active interface 1 and the butt joint shell 5 of the passive interface 2 are mutually matched and are in butt joint with the electric connection module 5, so that the active interface 1 and the passive interface 2 are mutually in butt joint and can realize electric connection, and meanwhile, the active interface 1 and the passive interface 2 are in locking connection or are mutually separated through the active locking module 4 and the passive locking hook 21.
It can be appreciated that the electrical connection module 5 disposed on the active interface 1 and the passive interface 2 is used to implement electrical connection between the active interface 1 and the passive interface 2, and many embodiments of the electrical connection module exist in the prior art, which is not described in detail herein. In a specific embodiment, the electric connection module 5 is provided with a thimble and a through hole matched with the thimble, and the active interface 1 and the passive interface 2 are electrically connected through the thimble and the through hole matched with each other on the electric connection module 5; in another alternative embodiment, two electromagnetic materials with different magnetism are arranged on the electric connection module 5, and the active interface 1 and the passive interface 2 are electrically connected through the electromagnetic materials matched with each other on the electric connection module 5.
It will also be appreciated that the docking housing 3 is configured such that the active interface 1 and the passive interface 2 are relatively matingly docked. The structure of the docking shell 3 is also in many embodiments in the prior art. In a preferred embodiment, referring to fig. 5, the docking housing 3 includes a cylindrical docking body 31, a trapezoidal guide flap 32, a trapezoidal guide groove 33, and a docking side 34. The trapezoidal guide flaps 32 and the trapezoidal guide grooves 33 are preferably provided in four each, and the four trapezoidal guide flaps 32 and the four trapezoidal guide grooves 33 are all arranged at the working end of the docking shell 3 (i.e., the end of the docking shell on one interface close to the other interface), and when the two interfaces are required to be in a relatively matched docking arrangement, the trapezoidal guide flaps 32 and the trapezoidal guide grooves 33 of the two docking shells 3 arranged on the two interfaces can be mutually docked. On both sides of each trapezoidal guide flap 32 are abutment sides 34, the abutment sides 34 providing the two abutment shells 3 with the ability to resist torque in the direction of rotation about the axis. Specifically, the trapezoidal surfaces of the trapezoidal guide vane 32 and the trapezoidal guide groove 33 are each provided obliquely toward the working end, and when one of them is provided obliquely toward the outer diameter direction of the cylinder of the butt joint body 31, the other is provided obliquely toward the inner diameter direction of the cylinder. The butt-joint side face 34 is connected with the adjacent trapezoid guide flap 32 and the trapezoid guide groove 33; when four trapezoidal guide flaps 32 and four trapezoidal guide grooves 33 are provided, 8 abutting side surfaces 34 are provided. At this time, since the guide flap is inclined from top to bottom, the guide groove is also inclined like a slope, and the design can enable the two butt joint shells to have larger displacement tolerance in the radial direction when moving left and right.
Referring to fig. 2-9, the structure of the active interface 1 is discussed in detail below.
The active locking module 4 of the active interface 1 comprises an active component, a driving member 45 and a bearing 46. The active component comprises an active latch hook 41 and a drive pin 42 which are fixedly connected. The bearing 46 is preferably a deep groove ball bearing.

The cam 68 is provided with a guide groove 681 on an outer wall for guiding the roller 43 to be movable along a set trajectory. Of course, the guide groove 681 may be formed to penetrate the inner and outer walls of the cam 68.

The follower 411 and the driving pin 42 passing through the pin hole 4111 are fixedly connected by a nut 44 provided thereon, so that the follower 411 of the active lock hook 41 and the driving pin 42 remain relatively stationary. Two drive pins 42 are disposed in the fitting groove 453 on the side remote from the cam 68. The two driving pins 42 are fixedly connected with rollers 43 on one side close to the cam 68, the rollers 43 are matched with guide grooves 681 on the outer wall of the cam 68, and then the driving pins move along the set track under the limitation of the guide grooves 681, so that the purpose of driving the active lock hook 41 to move along the set track is achieved. Of course, the manner of fixing the driving pin 42 to the active latch hook 41 is not limited, as long as the fixing can be achieved, for example, in an alternative embodiment, the driving pin 42 is welded to the active latch hook 41. It will be appreciated that the roller 43 is provided for the purpose of reducing friction as the drive pin 42 moves along the guide slot 681, and that the roller 43 need not be provided, in an alternative embodiment, the end of the drive pin 42 adjacent the cam 68 is disposed directly on the guide slot 681 and moves along a set trajectory under the guidance of the guide slot 681.
The motor 71 in the drive 7 is fixed to the side of the drive chassis 6 of the drive interface 1 remote from the passive interface 2 and its output engages the drive 45 through the drive chassis 6. The output end of the motor 71 is provided with a spur gear to be in meshed connection with the gear teeth 451 on the driving member 45, and the motor 71 is sealed by a motor sealing sleeve 72 outside the motor 71.
It will be appreciated that the output of the motor 71 is eccentrically disposed on the drive chassis 6 and does not interfere with the cam 68 and causes the output of the motor 71 to engage the gear teeth 451 of the driver 45. That is, the motor mounting hole 61 is eccentrically provided on the active chassis 6 such that the output end of the motor 71 is eccentrically provided with respect to the active chassis 6, and the cam 68, the active lock hook 41 and the driving piece 45 are coaxially provided with respect to the active chassis 6, and the outer arm of the cam 68 and the output end of the motor 71 do not interfere with each other.
The inner wall of the bearing 46 is in interference connection with the protruding portion 452 of the driving piece 45, and the outer wall of the bearing 46 is in interference connection with the inner wall of the docking shell 3, and as the docking shell 3 is fixedly arranged on the driving chassis 6, the outer wall of the bearing 46 is still relative to the driving chassis 6, and the driving piece 45 can rotate relative to the driving chassis 6 while the driving piece 45 is supported by the driving chassis 6. The bearing 46 is a ball bearing, preferably a deep groove ball bearing, which is well suited to the practice of the present invention. There are numerous embodiments of the bearing 46 in the prior art and detailed description thereof will not be repeated.
It will be appreciated that the inner wall of bearing 46 does not interfere with the end of drive pin 42 remote from cam 68. In a preferred embodiment, the end of the driving pin 42 away from the cam 68 is just accommodated in the adapting groove 453 of the driving member 45, that is, the end of the driving pin 42 away from the cam 68 is just flush with the outer wall of the driving member 45 at the portion where the adapting groove 453 is located, at this time, since the protruding portion 452 protrudes from the outer wall of the driving member 45 at the portion where the adapting groove is located, the bearing 46 is tightly connected with the protruding portion 452, so that the interference between the inner wall of the bearing 46 and the end of the driving pin 42 away from the cam 68 can be well achieved.
When two sub-mirror modules 10 need to be connected or disconnected, the output end of the motor 71 of the driving device 7 rotates to drive the driving piece 45 to rotate. Since one side of the driving pin 42 is disposed in the fitting groove 453 and the other side is disposed in the guide groove by the roller 43, the driving pin 42 is fixedly connected with the active latch hook 41. Under the condition that the driving member 45 rotates, the driving member 45 drives the driving pin 42 to move, so that one end of the driving pin 42, which is close to the cam 68, moves along the designated track in the guiding groove 681, and the other end of the driving pin is driven in the adapting groove 453, so as to drive the driving latch hook 41 to move along the designated track, thereby completing the locking connection or mutual separation with the passive latch hook 21 of the passive interface 2.
It will be appreciated that there is a particular interest in locating the output of the motor 71 of the drive means 7 within the drive member 45 and having the output of the motor 71 engage with the teeth 451 on the inner wall of the drive member 45: referring to fig. 1, when the sub-mirror modules 10 of the space telescope are in butt joint or separation, the size of the interface, especially the active interface, needs to be made as small as possible, so that the size of the single sub-mirror module 10 can be further reduced, the sub-mirror modules 10 in a unit area can be increased while the space is conveniently transported, and further more accurate and fine adjustment of the mirror surface can be realized; meanwhile, the contact area between the interfaces under the same interface area needs to be increased as much as possible, so that the fault tolerance rate during connection or separation between the interfaces is better increased. That is, in designing an active interface, it is desirable to increase the contact area between interfaces as much as possible in the radial position of the interfaces. By engaging the output end of the motor 71 with the gear teeth 451 on the inner wall of the driving member 45, the motor 71 can be located in the radial area where the docking shell 3 is located, so that the radial dimension of the active interface 1 is the contact area between the interfaces, and the occupation ratio of the contact area when the two interfaces are contacted is ensured to the maximum.
Thus, by arranging the output end of the motor 71 in the driving member 45 and engaging with the gear teeth 451 on the inner wall of the driving member 45, by fixing the inner wall of the bearing relatively to the outer wall of the driving member 45 and fixing the outer wall of the bearing relatively to the inner wall of the docking housing 3, the docking housing 3 is arranged on the driving chassis 6 and the driving pin 42 is fixedly connected with the driving latch hook 41, the cam 68 is fixedly arranged on the driving chassis 6, the cam 68 is provided with the guide groove 681, the driving latch hook 41 is arranged between the cam 68 and the driving member, one end of the driving pin 42 close to the cam 68 is arranged in the guide groove 681, one end of the driving pin 42 close to the driving member is arranged in the fit groove 453, and when the driving member 45 rotates under the action of the output end of the motor 71, the driving pin 42 moves in a predetermined direction under the action of the guide groove 681 and the fit groove 453, thereby realizing the locking connection with another interface or mutual separation.
With continued reference to fig. 3-4, and fig. 8-9, the outer wall of the cam 68 adjacent to one side of the driving chassis 6 is recessed inward, and the range of the inner wall of the cam 68 includes the position where the motor 71 engages with the gear teeth 451 of the driving member 45, so as to further increase the gap between the cam 68 and the output end of the motor 71, and further avoid mutual interference.
With continued reference to fig. 4-5, a notch is disposed on a side of the inner wall of the docking shell 3, which is close to the active chassis 6, i.e. a side of the inner wall of the docking shell 3, which is close to the active chassis 6, protrudes outwards, and an outer wall of the bearing 46 is fixedly connected to the protruding portion of the inner wall of the docking shell 3, so as to further increase the size of the driving member 45, and simultaneously limit the axial movement of the bearing 46, thereby limiting the axial movement of the driving member 45.
Further, referring to fig. 4, the active locking module 4 further includes a bearing retainer ring 47, where one side of the bearing retainer ring 47 abuts against the bearing 46, and the other side abuts against the active chassis 6, so as to further limit the axial position of the bearing 46, and avoid the axial movement of the driving member 45 after long-time rotation, so as to implement axial constraint on the bearing 46 and the driving member 45.
With continued reference to fig. 3-4, and fig. 7-8, the guide slot 681 and the mating slot 453 are the same size and correspond to each other in the axial direction, i.e., are located at the same position in the axial direction. The adapting groove 453 is axially arranged, and the guiding groove 681 is in a structure of 'axially and obliquely ascending-axially and horizontally-axially and obliquely descending', so that the locking connection or mutual separation of the active interface 1 and the passive interface 2 can be well realized. Taking a locking connection as an example, when the driving pin 42 moves from "axially obliquely upward to axially horizontally" of the guiding slot 681 under the guiding of the guiding slot 681, the driving pin 42 drives the active lock hook 41 to axially upward and rotate, at this time, one end of the driving pin 42 near the driving member 45 just moves to the axial top end of the guiding slot 681, and the active lock hook 41 can move between the axial positions of the passive lock hook 21 and the passive chassis post 22 without interference, i.e. move to a position above the passive lock hook in the axial direction, and the active lock hook 41 and the passive lock hook 21 do not interfere with each other in the circumferential direction. When the driving pin 42 moves from the "axial horizontal direction to the axial inclined direction" under the guidance of the guiding slot 681, the driving pin 42 drives the active lock hook 41 to move downward and rotate in the axial direction, and at the same time when one end of the driving pin 42, which is close to the driving member 45, moves axially from the axial top end of the guiding slot 681 to the other end, the active lock hook 41 moves from the direction of the passive chassis column 22 to the passive lock hook 21, that is, the active lock hook 41 moves in the circumferential direction toward the passive lock hook 21 while the active lock hook 41 moves from the direction of the passive chassis column 22 to the passive lock hook 21 in the axial direction. When the driving pin 42 just moves to the end point of the guide slot 681, the driving latch hook 41 just connects with the passive latch hook 21 tightly, that is, the axial position and the circumferential position overlap, so as to realize the tight connection between the driving interface 1 and the passive interface 2.
When the two sub-mirror modules 10 need to be separated, that is, when the two interfaces need to be separated, the driving pin 42 moves from "axially obliquely downward to axially horizontally" under the guidance of the guiding slot 681, the driving pin 42 drives the active lock hook 41 to axially rise and rotate, at this time, one end of the driving pin 42, which is close to the driving piece 45, moves toward the axial top end of the guiding slot 681, and makes the active lock hook 41 move rotationally toward the passive chassis column 22, that is, at this time, the active lock hook 41 moves axially from the passive lock hook 21 toward the passive chassis column 22, and the active lock hook 41 moves circumferentially away from the passive lock hook 21; when the driving pin 42 moves from "axial horizontal to axial oblique upward" under the guidance of the guiding slot 681, the driving pin 42 drives the active lock hook 41 to axially descend and rotate, at this time, one end of the driving pin 42, which is close to the driving piece 45, moves to the axial top end of the guiding slot 681, then moves axially to the other end, and makes the active lock hook 41 move from the passive chassis column 22 to the active interface 1 without interfering with the passive lock hook 21, i.e. at this time, the active lock hook 41 moves from the passive chassis column 22 to the active chassis 6 in the axial direction, and the active lock hook 41 continues to move in the direction away from the passive lock hook 21 in the circumferential direction; when the driving pin 42 just moves to the end point of the guide slot 681, the active lock hook 41 just resets to the initial position of the active interface 1, so as to separate the active interface 1 and the passive interface 2 from each other.
It will be appreciated that the structures of the guide groove 681 and the adapting groove 453 are set differently, which has different meanings, on the one hand, if the guide groove 681 and the adapting groove 453 are set to the same structure, the manufacturing cost of the whole driving member 45 will be increased due to the complex groove structure of the adapting groove 453 itself, and the requirement on the manufacturing precision thereof will be high; on the other hand, the guide groove 681 and the adapting groove 453 are provided with different structures, especially, the adapting groove is only provided with an axial groove, so that a larger degree of freedom can be generated when the active lock hook 41 and the passive lock hook 21 are tightly connected or separated from each other, and the fault tolerance when the active lock hook 41 and the passive lock hook 21 are connected or separated is further increased, and the success rate of space operation is greatly increased.
With continued reference to fig. 1 and 4, the active chassis 6 is fixed on the outer wall of the truss 101 of the sub-mirror module 10, and in another alternative embodiment, the active chassis 6 is the truss 101 of the sub-mirror module 10, where the motor 71 and the motor sealing sleeve 72 are accommodated in the cavity of the truss 101 and do not interfere with the adjusting device 103, which has the advantage of further reducing the space occupied by the interface on the sub-mirror module.
With continued reference to fig. 4, the electrical connection module 5 of the active interface 1 is disposed on a surface of the locking portion 412 of the active latch hook 41 near the passive interface. Correspondingly, the electrical connection module 5 of the passive interface 2 is arranged on the side of the passive chassis post 22 close to the active interface 1.
With continued reference to fig. 2, the passive latch hook 21 is fixedly connected to the passive chassis column 22, in a preferred embodiment, an end of the passive latch hook 21 away from the latch hook is fixedly connected to a protruding portion of an inner wall of the docking shell 3 of the passive interface 2 by a screw, an isomorphic latch hook 211 matched with the latch hook 4121 of the active latch hook 41 is disposed on a side of the passive latch hook 21 away from the passive chassis column 22, and the isomorphic latch hook 211 and the latch hook 4121 of the active latch hook 41 are isomorphic and are mutually matched in position, so as to facilitate connection and disconnection of the active latch hook 41 and the passive latch hook 21.
Further, the locking portion 412 of the active locking hook 41 is provided with four locking hooks 4121, the four locking hooks 4121 are designed in a 90 ° rotationally symmetrical manner, correspondingly, the passive locking hook 21 is also provided with four isomorphic locking hooks 211, and the four isomorphic locking hooks 211 are designed in a 90 ° rotationally symmetrical manner.
Further, the hook lock 4121 or the isomorphic lock hook 211 is shaped like a Chinese character 'zhi', and the axial height of the end near the axle center in the radial plane is higher than the axial height of the end far away from the axle center, so as to further increase the tightness when the two interfaces are connected.
The process of connection and disconnection between the two sub-mirror modules 10 is further described below to facilitate a better understanding of the sub-mirror docking interface of the spatial telescope of the present invention.
The main process of assembling and connecting the sub-mirror modules 10 by using the docking interface of the present invention is divided into four stages of docking, locking and separating.
Stage before butt joint: in the pre-docking stage, the active interface 1 and the passive interface 2 are respectively installed on the two sub-mirror modules 10, the active lock hook 41 of the active interface 1 is in a retracted and reset state, and the active interface 1 and the passive interface 2 respectively arranged on the two sub-mirror modules 10 are in a free docking state.
Docking stage: the docking stage starts, and under the action of other devices, for example, a mechanical arm grabs one sub-mirror module 10, so that the active interface 1 on one sub-mirror module 10 is close to the passive interface 2 on the other sub-mirror module 10, and the docking shells 3 on the two sub-mirror modules are basically matched.
Locking: after the two docking shells 3 are basically engaged, the locking stage begins, the motor 71 starts the spur gear at the output end thereof to mesh with the internal gear of the driving member 45, driving the driving member 45 to rotate, the cam 68 is in a static state due to the fixation with the driving chassis 6, and the driving pin 42 is fixedly connected with the driving latch hook 41 by the nut 44. And one end of the driving pin 42 is cooperatively connected with the notch of the adapting groove 453 of the driving member 45, so as to allow the active lock hook 41 to axially move, the other end of the driving pin 42 is connected with the roller 43, the roller 43 is cooperatively connected with the guiding groove 681 of the cam 68, the rotation rising angle and distance of the active lock hook 41 are limited, finally, one end of the driving pin 42 moves in the adapting groove 453 of the driving member 45, and the other end moves in the guiding groove 681 of the cam 68 along a preset position, so as to drive the active lock hook 41 to complete a 'rotation rising-shrinking engagement' process in the butting direction, thereby realizing the tight cooperative connection of the active lock hook 41 and the passive lock hook 21, and the shrinking engagement process not only enables the tight connection of the active interface 1 and the passive interface 2, but also can correct the tiny errors of the two butting shells 3 in the butting stage, and completes the connection of the two electric connection modules 5, thereby realizing the mechanical and electric connection of the active interface 1 and the passive interface 2.
Separation: when the sub-mirror module 10 needs to be maintained and upgraded, the docking interface needs to be unlocked, the motor 71 is used for reversely driving the active lock hook 41 to retract along the locking path to complete the unlocking process, and at the moment, the active interface 1 and the passive interface 2 can be freely separated.
It will be appreciated that the above is described in detail with respect to the manner in which the connection between the two sub-mirror modules is released, and in particular, the manner in which an active interface is connected to and released from a passive interface. For the connection release mode of the active interface and the passive interface, the connection release mode is the same as that of the active interface and the passive interface, and only one of the active interfaces does not start the driving device, so that the active interface and the passive interface have the same function.
Of course, the invention also provides an active structure for the space telescope sub-mirror butt joint structure, and the active structure is the same as the active structure in the space telescope sub-mirror butt joint structure, and detailed description is omitted.
Of course, the invention also provides a ground simulation adjustment system of the space telescope, which is used for simulating the butt joint of the sub-mirrors of the space telescope on the ground and comprises a sub-mirror butt joint structure, wherein the structure of the sub-mirror butt joint structure is the same as that of the sub-mirrors of the space telescope, and detailed description is omitted.
