Description

Technical Field

[0001] The present invention relates to the field of satellite adjustment technology, and in particular to an adjustment device and a satellite. Background Art

[0002] When a satellite is in orbit, its center of mass will change due to factors such as fuel consumption, boost gas removal, and the deployment of large onboard structures. This shift in the center of mass and center of gravity will affect the satellite's normal operation. To ensure that the satellite's center of mass and center of gravity remain relatively consistent, a satellite center of mass adjustment system is required.

[0003] In related technologies, a screw guide rail mechanism is usually used to adjust the center of mass of the satellite. However, the screw guide rail mechanism is usually composed of a guide rail, a slider, a support, a motor, a screw nut, a mass block, a grating scale, a photoelectric switch, etc., and has a complex structure. At the same time, only the mass block plays the role of adjusting the center of mass of the satellite, thereby reducing the adjustment efficiency of the device. Summary of the Invention

[0004] The problem solved by the present invention is how to improve the center of mass adjustment efficiency of the device.

[0005] In order to solve the above problems, the present invention provides an adjustment device and a satellite.

[0006] In the first aspect, the present invention provides an adjustment device for adjusting the center of mass of a satellite, including an adjustment component movably connected to the satellite, the adjustment component including: a blocking member including a first shell and a first deformable structure, the first shell having a first accommodating cavity and a first opening connected to the first accommodating cavity, the first deformable structure being at least partially installed in the first accommodating cavity, the middle part of the first deformable structure being able to contact the outer peripheral wall of the satellite to limit the displacement of the adjustment member, and the middle part of the first deformable structure being able to deform relative to the first shell in a direction away from the first opening; at least two driving members being respectively connected to the two ends of the blocking member along the first direction, each of the driving members including a second shell connected to the first shell and a second deformable structure, the second shell having a second accommodating cavity and a first opening connected to the second accommodating cavity The second opening is connected to the second housing cavity, and one end of the second deformation structure is installed in the second accommodating cavity. The middle part of the second deformation structure can produce a convex deformation in the second direction relative to the first shell, so that the other end of the second deformation structure contacts the outer wall of the satellite to drive the blocking member to move along the first direction, and the first direction and the second direction are perpendicular to each other; a heating member, the first deformation structure and the second deformation structure are both provided with the heating member, and the heating member is used to heat the corresponding first deformation structure and / or the second deformation structure so that the first deformation structure and / or the second deformation structure are deformed; wherein, the driving members located on both sides of the blocking member are operated selectively, and the driving member located on one side of the blocking member is used to drive the blocking member and the driving member located on the other side of the blocking member to move.

[0007] The beneficial effects of the regulating device of the present invention are: At least two driving members are respectively connected to the two ends of the blocking member, and the driving members on both sides are selectively operated. When no adjustment is required, the first deformation structure of the blocking member can contact the outer wall of the satellite to form a block to prevent the device and the satellite from relative displacement. When adjustment is required, the second deformation structure of the driving member on one side of the blocking member produces a convex deformation along the second direction under the action of the heating member. The middle part of the first deformation structure of the blocking member is deformed relative to the first shell in a direction away from the first opening under the action of the heating member, so that the first deformation structure is away from the outer wall of the satellite, and the other end is in contact with the outer wall of the satellite. The contact with the surrounding wall generates a driving force, which can drive the blocking member and the driving member on the other side to move in the first direction, so that the driving force can be converted into the displacement of the adjustment component to meet the movement requirements of the adjustment component, and the first deformation structure and the second deformation structure are both deformed by the heating element to achieve deformation control. Compared with the mechanical transmission adjustment device, the thermally driven deformation response speed is faster, the time from heating to effective deformation is short, and the degree of deformation can be precisely controlled by the heating temperature, which can achieve rapid adjustment of small displacements, which can greatly shorten the overall adjustment time and thus improve the adjustment efficiency of the satellite center of mass.

[0008] Optionally, the second deformation structure includes: a second body, one end of the second body is installed in the second accommodating cavity, and the second body is provided with the heating element; a pushing element is provided at the other end of the second body, and the pushing element is used to contact the outer peripheral wall of the satellite to drive the blocking element to move along the first direction; wherein, when the adjustment component is in the fixed mode, the middle part of the second body protrudes out of the second shell setting through the second opening, and when the adjustment component switches from the fixed mode to the adjustment mode, the heating element located on one side of the blocking element heats the second body corresponding to it, so that the middle part of the second body is convex and deformed in the direction away from the second opening, and the pushing element contacts the outer peripheral wall of the satellite. When the adjustment component is in the adjustment mode, the heating element stops heating, so that the middle part of the second body gradually changes from a convex section to a straight section, and the blocking element is pushed to move by the friction between the pushing element and the outer peripheral wall of the satellite.

[0009] Optionally, the first shell, the second shell and the pushing member are made of carbon fiber material.

[0023] like Figures 1 to 5 As shown, in the first aspect, the present invention provides an adjustment device for adjusting the center of mass of a satellite, including an adjustment component movably connected to the satellite, the adjustment component including: a blocking member 10, including a first shell 11 and a first deformable structure 12, the first shell 11 having a first accommodating cavity 13 and a first opening 14 connected to the first accommodating cavity 13, the first deformable structure 12 is at least partially installed in the first accommodating cavity 13, the middle part of the first deformable structure 12 can contact the outer peripheral wall of the satellite to limit the displacement of the adjustment component, and the middle part of the first deformable structure 12 can also be deformed relative to the first shell 11 in a direction away from the first opening 14; at least two driving members 20 are respectively connected to the two ends of the blocking member 10 along the first direction, each driving member 20 includes a second shell 21 connected to the first shell 11 and a second deformable structure 22, the second shell 21 has a second accommodating cavity 23 to limit the displacement of the adjustment component. And a second opening 24 connected to the second accommodating cavity 23, one end of the second deformable structure 22 is installed in the second accommodating cavity 23, and the middle part of the second deformable structure 22 can produce a convex deformation relative to the first shell 11 in the second direction, so that the other end of the second deformable structure 22 contacts the outer wall of the satellite to drive the blocking member 10 to move along the first direction, and the first direction and the second direction are perpendicular to each other; a heating element, a heating element is provided on the first deformable structure 12 and the second deformable structure 22, and the heating element is used to heat the corresponding first deformable structure 12 and / or second deformable structure 22 so that the first deformable structure 12 and / or second deformable structure 22 are deformed; wherein, the driving elements 20 located on both sides of the blocking member 10 are operated selectively, and the driving element 20 located on one side of the blocking member 10 is used to drive the blocking member 10 and the driving element 20 located on the other side of the blocking member 10 to move.

[0024] In this embodiment, at least two driving members 20 are respectively connected to the two ends of the blocking member 10, and the driving members 20 on both sides are selectively operated. When no adjustment is required, the first deformation structure 12 of the blocking member 10 can contact the outer wall of the satellite to form a block to prevent the device and the satellite from relative displacement. When adjustment is required, the second deformation structure 22 of the driving member 20 on one side of the blocking member 10 is convexly deformed in the second direction under the action of the heating member. The middle part of the first deformation structure 12 of the blocking member 10 is deformed relative to the first shell 11 in a direction away from the first opening 14 under the action of the heating member, so that the first deformation structure 12 is away from the outer wall of the satellite. The other end of the movable member 10 contacts the outer wall of the satellite and generates a driving force, which can drive the blocking member 10 and the driving member 20 on the other side to move in the first direction, so that the driving force can be converted into the displacement of the adjustment component to meet the movement requirements of the adjustment component, and the first deformation structure 12 and the second deformation structure 22 are both deformed by the heating element to achieve deformation control. Compared with the mechanical transmission adjustment device, the thermally driven deformation response speed is faster, the time from heating to effective deformation is short, and the degree of deformation can be precisely controlled by the heating temperature, which can achieve rapid adjustment of small displacements, thereby greatly shortening the overall adjustment time, thereby improving the adjustment efficiency of the satellite center of mass. In this embodiment, the adjustment system includes three adjustment components, and the three adjustment components move along the first direction, the second direction, and the third direction respectively, thereby changing the position of the satellite's center of mass.

[0025] In this embodiment, the heating element can be a heating wire. Because the heating wire heats up rapidly, it can quickly transfer heat to the first deformable structure 12 and the second deformable structure 22, allowing them to quickly reach the desired deformation temperature. This significantly shortens the deformation response time and indirectly improves the efficiency of center of mass adjustment. Furthermore, the heating wire has a simple structure and compact size, which does not occupy excessive installation space and avoids the structural redundancy caused by excessively large heating elements. Optionally, the first deformation structure 12 includes: a first main body 121, which is installed in the first accommodating cavity 13; a rubber part 122, which is arranged on the side wall of the first main body 121 near the first opening 14, and a heating part is provided between the first main body 121 and the rubber part 122; wherein, the adjustment component has a fixed mode and an adjustment mode, when the adjustment component is in the fixed mode, the extension direction of the first main body 121 and the rubber part 122 is parallel to the first direction, the rubber part 122 is located on the outside of the first shell 11 and contacts the outer peripheral wall of the satellite to limit the displacement of the adjustment component, when the adjustment component is in the adjustment mode, the heating part heats the first main body 121 and the rubber part 122 located on the side of the blocking member 10, so that the first main body 121 and the rubber part 122 are deformed in a direction away from the first opening 14, so that the rubber part 122 is separated from the outer peripheral wall of the satellite.

[0026] By setting the above structure, in the fixed mode, the extension direction of the first body 121 and the rubber part 122 is parallel to the first direction, and the rubber part 122 is located outside the first shell 11 and contacts the outer peripheral wall of the satellite. With the help of the elastic deformation characteristics of the rubber part 122, it can fit closely to the surface of the satellite to form a stable resistance effect, effectively limiting the displacement of the adjustment component. When switching to the adjustment mode, the heating element heats the first body 121 and the rubber part 122 on one side of the resistance element 10, and both the first body 121 and the rubber part 122 are deformed in the direction away from the first opening 14, so that the rubber part 122 is quickly separated from the outer peripheral wall of the satellite to eliminate resistance. The above setting can make the mode switching response of the device faster, so as to further improve the adjustment efficiency of the device.

[0027] In this embodiment, the first body 121 and the rubber member 122 are flat plates in a low-temperature state and are in an arch bridge shape similar to the letter "Ω" in a high-temperature state. When powered on, they are heated to a high-temperature state, and when powered off, they are cooled to return to a low-temperature state. The rubber member 122 is a rubber with a high friction coefficient. When powered on, it clings to the wall surface, and when powered on, it detaches from the wall surface, eliminating the resistance to the device.

[0028] Optionally, the second deformation structure 22 includes: a second body 221, one end of the second body 221 is installed in the second accommodating cavity 23, and a heating element is provided on the second body 221; a pushing member 222 is provided at the other end of the second body 221, and the pushing member 222 is used to contact the outer wall of the satellite to drive the blocking member 10 to move along the first direction; wherein, when the adjustment component is in the fixed mode, the middle part of the second body 221 protrudes from the second shell 21 through the second opening 24, and when the adjustment component is switched from the fixed mode to the adjustment mode, the heating element located on one side of the blocking member 10 heats the corresponding second body 221, so that the middle part of the second body 221 convexly deforms in the direction away from the second opening 24, and the pushing member 222 contacts the outer wall of the satellite. When the adjustment component is in the adjustment mode, the heating element stops heating, so that the middle part of the second body 221 gradually changes from a convex section to a straight section, and the friction between the pushing member 222 and the outer wall of the satellite pushes the blocking member 10 to move.

[0029] By setting the above structure, in the fixed mode, the middle part of the second body 221 protrudes from the second shell 21 through the second opening 24. At this time, the pushing member 222 does not form effective contact with the outer wall of the satellite and will not generate driving force, thereby ensuring the stability of the adjustment component in the blocking state. When switching to the adjustment mode, the heating element heats the corresponding second body 221, causing its middle part to bulge and deform in the direction away from the second opening 24, and the pushing member 222 then contacts the outer wall of the satellite and forms a reliable abutment. After switching to the adjustment mode, the heating element stops heating, and the middle part of the second body 221 gradually changes from a convex section to a straight section. During this deformation recovery process, the pushing member 222 will generate relative motion with the wall during the deformation process to generate friction, thereby pushing the blocking member 10 to move along the first direction. The above setting can make the mode switching response of the device faster, so as to further improve the adjustment efficiency of the device.

[0030] In this embodiment, the second body 221 is in an inverted "Ω" shape in a low temperature state and an arch bridge shape similar to the letter "Ω" in a high temperature state. It will become a high temperature state when heated after power is turned on and will return to a low temperature state when cooled after power is turned off.

[0031] Optionally, the first shell 11 , the second shell 21 and the pushing member 222 are made of carbon fiber material.

[0032] By setting up the above structure, due to the lightweight characteristics of carbon fiber material, the weight of the first shell 11, the second shell 21 and the pushing member 222 can be greatly reduced while ensuring the structural strength. The lightweight structure can make the driving member 20 have less inertia to overcome when driving the adjustment component to move, thereby reducing energy consumption. In addition, the carbon fiber material deforms very little when the temperature changes. In this way, the dimensional changes of the first shell 11 and the second shell 21 can be ignored when the heating element is working and the temperature of the space environment fluctuates, and there will be no interference with the deformation of the first deformable structure 12 and the second deformable structure 22, ensuring that the deformable structure can be accurately deformed according to the preset trajectory, thereby improving the accuracy of the adjustment.

[0033] Optionally, the first body 121 and the second body 221 are made of a two-way shape memory polymer material.

[0034] By setting the above structure, the bidirectional shape memory polymer can maintain two preset forms at different temperatures, and can achieve precise switching between the two forms through temperature changes. In the fixed mode, the first body 121 and the rubber part 122 jointly maintain an extension state parallel to the first direction, and the rubber part 122 contacts the outer wall of the satellite to achieve resistance; when switching to the adjustment mode, the heating element heats the first body 121 to deform, driving the rubber part 122 to move away from the first opening 14 and detach from the satellite surface, releasing the resistance. When the heating is stopped, the first body 121 can automatically return to the initial extension state by virtue of the memory properties of the material, so that the rubber part 122 contacts the satellite again and quickly switches back to the fixed mode. This can make the switching action faster and more accurate, further improving the adjustment efficiency of the device. In the fixed mode, the middle part of the second body 221 protrudes from the second shell 21 through the second opening 24. When the second body 221 is heated, it convexly deforms in a direction away from the second opening 24 according to a preset trajectory, and the pusher 222 contacts the satellite. After the heating stops, the second body 221 automatically returns to a straight section, and the friction between the pusher 222 and the satellite drives the adjustment component to move. This can make the switching action faster and more accurate, further improving the adjustment efficiency of the device. Optionally, the number of driving members 20 located on both sides of the blocking member 10 is the same.

[0035] By setting up the above structure, it can be ensured that the driving force of the adjustment component is consistent when it moves in both directions, so that the adjustment component can have the same acceleration, speed change law and displacement control accuracy when moving in the positive and negative directions along the first direction, ensuring the consistency of the satellite center of mass during the bidirectional adjustment process and avoiding adjustment deviations caused by asymmetric driving force. Optionally, the first shell 11 is connected to the second shell 21 by snap-fitting.

[0036] In this embodiment, a slot is provided on the first shell 11 , and a buckle is provided on the second shell 21 .

[0037] The above-described structure enables quick assembly through the pre-set slots and snap-fit ​​mechanism on the first and second housings 11, 21. This significantly shortens assembly time, reduces assembly steps, and lowers labor costs. Furthermore, the snap-fit ​​mechanism boasts high positioning accuracy, ensuring that the first and second housings 11, 21 maintain their pre-set relative position after assembly. This prevents uneven force on the driver 20 and the blocker 10 due to connection deviation, thereby ensuring the overall structural stability of the adjustment assembly. Optionally, the regulating device further includes: a power supply electrically connected to the heating element to provide electrical energy to the heating element; and a controller communicatively connected to the power supply, the controller being configured to control the power supply to be turned on or off.

[0038] By setting the above structure, the cooperation of the controller and the power supply realizes the intelligent control of the working state of the heating member. The controller can automatically determine whether to start the adjustment action according to the real-time monitoring data of the satellite centroid, and accurately control the working state of the heating member by controlling the opening or closing of the power supply. For example, when the satellite attitude sensor detects that the centroid deviates beyond the preset range, the controller will immediately send a command to the power supply to supply power to the corresponding heating member, so as to make the first deformation structure 12 or the second deformation structure 22 deform to start the adjustment process. When the centroid returns to the reasonable range, the controller can timely cut off the power supply to stop heating, thereby avoiding energy waste and improving the adjustment efficiency of the device.

[0039] In the embodiment, the size of the power supply can be freely adjusted according to the number of driving members 20, and there are enough power supply slots. The power supply can be in standby mode in a stable state to save power.

[0040] Meanwhile, in the embodiment, the power supply and the controller are arranged on the blocking member 10, and the density of the assembled quality unit can be customized and adjusted to match the blocking member 10 and the driving member 20 to adjust the efficiency and accuracy of the centroid adjustment.

[0041] In the embodiment, when the device is in the fixed mode: the power supply is in the off state, and the second deformation structure 22 is in the low-temperature state reverse "Ω" type. At this time, the push member 222 located at the end of the second deformation structure 22 is in a suspended state, and the push member 222 does not contact the wall of the satellite. Only the convex part of the reverse "Ω" type of the second deformation structure 22 contacts and supports the wall of the satellite, ensuring the consistency of the height of the device, and avoiding the influence of the imbalance of the height of the device on the centroid. The first deformation structure 12 is in a low-temperature flat plate state at this time, and the rubber member 122 is tightly attached to the wall. Due to the high friction coefficient, the blocking effect is good, thereby ensuring the stability of the device in the fixed mode.

[0042] In the dynamic adjustment mode: the power supply is in the on state, the second deformation structure 22 corresponding to the forward direction is heated to change to the high-temperature state "Ω" type. At this time, the push member 222 located at the end of the second deformation structure 22 is tightly attached to the wall of the satellite. Since the first deformation structure 12 is still not separated from the wall, and the reaction force provided by the rubber member 122 is greater than or equal to the force provided by the push member 222 during deformation, the device will not move in the opposite direction to cause slipping and invalidation of the driving. After the second deformation structure 22 changes to the high-temperature state "Ω" type, the first deformation structure 12 is heated to separate from the wall to eliminate the blocking effect on the device. Then, the heating of the second deformation structure 22 is stopped, and the second deformation structure 22 is cooled to return to the low-temperature state reverse "Ω" type. In this process, the push member 222 connected to the second deformation structure 22 contacts and rubs with the wall of the satellite to push the device forward.

[0043] Optionally, the adjusting device further comprises: a position feedback unit configured to obtain a real-time center-of-mass theoretical position of the satellite and generate a position signal; a master control unit configured to calculate subsequent theoretical position data of the satellite according to the position signal and form a sequence encoding signal; an operation control unit in communication connection with the controller and the master control unit, the operation control unit being configured to decode the sequence encoding signal and transmit the decoded signal to the controller; and a signal transmission unit in communication connection with the position feedback unit and the master control unit, respectively.

[0044] By setting the above structure, the position feedback unit can assist the overall satellite center-of-mass adjusting system to enhance the real-time feedback capability for center-of-mass adjustment, improve the adjustment precision and accuracy, and the position feedback unit is not limited to a certain form, which can use infrared distance measurement to measure the position in the satellite, can use a positioning rudder to determine the position of the driver, can also use a clear camera, a grating plate, etc. to obtain the position information of the intelligent driver; the operation control unit is used to improve the operation efficiency of the overall system, and the star-borne master control system or the ground base station master control system performs analog calculation to obtain accurate motion sequence encoding, the operation control unit analyzes and edits the queue of the encoding, improves the efficiency of the center-of-mass control, and relieves the operation pressure; the signal transmission unit is used to complete the real-time transmission of the signal, timely feedback the real-time position information of the driver, assist the overall system to perform real-time operation of the center-of-mass, and is also used to receive the encoding transmission of the master control system. Different signal transmission units have different numbers in the whole system, and accurate correct encoding is obtained when receiving the encoding. At the same time, more auxiliary accessories can be carried to assist the work of the auxiliary accessories, for example, satellite health detection accessories are carried, and the real-time health of the satellite is fed back to the master control system.

[0045] As shown in Figure 1 and Figure 2 In the present embodiment, the second deformation structure 22 is in a low-temperature anti-Ω shape, and the pushing member 222 at the end thereof is in a suspended state without contacting the wall of the satellite, and only the convex part of the anti-Ω shape of the second deformation structure 22 contacts and supports the wall of the satellite. The first deformation structure 12 is in a low-temperature flat plate state, and the rubber member 122 contacts the wall of the satellite.

[0046] As shown in Figure 3The figure shows the pre-preparation state of the adjustment mode, which is also the initial state diagram of the adjustment mode. The main control unit calculates the real-time theoretical position of the satellite's center of mass based on the pre-set satellite trajectory, calculates the subsequent theoretical position data of the intelligent driver based on the position data fed back by the position feedback unit, calculates the subsequent theoretical position data of the satellite based on the position signal and forms a sequence coding signal. The signal is received by the signal transmission unit, and then the calculation and control unit parses the code to sort the subsequent motion sequence. The power supply changes from the sleep standby state to the working state. According to the motion direction data provided by the motion code, the corresponding second deformation structure 22 is first heated to make it become a high-temperature "Ω" shape. At this time, due to a The first deformable structure 12 on one side has not left the satellite wall, and the friction between the rubber part 122 and the satellite wall is greater than the friction between the pushing part 222 and the satellite wall during the shape change of the second deformable structure 22. The second deformable structure 22 on the other side is still in the low-temperature inverted "Ω" shape at this time, and the part in contact with the satellite wall is only the smooth arch part. Due to the support of the second deformable structure 22 on the other side, the height of the second deformable structures 22 on both sides is balanced, and the overall positive pressure distribution remains consistent. Only the second deformable structure 22 completes the shape transformation from the low-temperature state to the high-temperature state, so that the device enters the propulsion pre-ready state.

[0047] like Figure 4 The figure shows the propulsion state in the adjustment mode. The controller controls the power supply to heat the first deformable structure 12 on one side, causing it to transform into a high-temperature "Ω" shape. The controller then controls the second deformable structure 22 to stop heating, allowing it to cool to a low-temperature inverted "Ω" shape. However, this transition is not complete, but rather only to a point near the intermediate state of its motion trajectory, completing the propulsion action. If there is a subsequent round of propulsion preparation, reheating can be performed to more quickly reach the propulsion pre-preparation state. If there is no subsequent round of propulsion preparation, further cooling can be performed to the low-temperature inverted "Ω" shape. During the transition to the intermediate flat state of the motion trajectory, the pusher 222 contacts the satellite wall, generating relative motion. At this time, because the middle portion of the second deformable structure 22 is suspended in the air, the friction coefficient between the pusher 222 and the satellite wall is higher than the friction between the first deformable structure 12 on the other side and the satellite wall, causing the intelligent device to move forward.

[0048] like Figure 5 As shown, this is the propulsion end state of the adjustment mode. The controller controls the power supply to stop heating the first deformable structure 12, so that it returns to a low-temperature flat plate shape and keeps close contact with the satellite wall. If the motion sequence has not ended, the next round of propulsion pre-preparation is carried out. The above pre-preparation and propulsion process are cycled to keep the device moving intermittently and evenly, and control the consistency of each round of propulsion. If the motion sequence has ended, the position feedback unit obtains the current position data of the device, and the signal transmission unit feeds back to the main control unit. If there is no next instruction, the power supply enters the sleep standby state and switches to the fixed mode.
