Description

Technical Field

[0001] The present invention relates to the technical field of super-elastic rod retraction and deployment, and more specifically, it relates to a pod honeycomb telescopic rod storage and deployment mechanism. Background Art

[0002] Super-elastic telescopic rods are widely used in deployable mechanisms due to their advantages such as light weight, large retraction ratio, and large deflection deformation. Super-elastic telescopic rods can use the elastic potential energy stored in their own bending to achieve self-deployment, and are widely used in thin-film antennas, solar sails, and drag sails. Several common super-elastic telescopic rods with different cross-sections include pod rods, humanoid rods, and circular energy storage telescopic rods. The pod honeycomb telescopic rod, also known as the pod honeycomb super-elastic telescopic rod, is formed by bonding two symmetric improved Ω-shaped strip springs. Since there is a smooth section in the middle of the improved Ω-shaped strip, compared with the traditional pod rod, it is very easy to topologically form a multi-cell pod honeycomb telescopic rod. The geometric structures of the unit cell and the multi-cell pod honeycomb telescopic rod are both symmetric about the left and right. The straight section is the bonding section. After being flattened along the cross-section, it has good flexibility to withstand large deformation curling and also has good stiffness during deployment.

[0003] When the current deployment mechanism retracts and deploys the super-elastic rod, in order to enable the super-elastic rod to be tightly wound around the drum, usually a spring is used to press the super-elastic rod against the drum by the pressure on the pressing wheel. However, as the winding thickness of the super-elastic rod on the drum increases, the compressed length of the spring also becomes larger. Therefore, the pressure of the pressing wheel on the super-elastic rod is also greater, which easily causes damage to the super-elastic rod. Moreover, due to the large pressure, the initial deployment process of the super-elastic rod is also more difficult. And during the deployment process, the super-elastic rod is also prone to slipping between the drum and the position without the pressing wheel, resulting in the super-elastic rod being difficult to deploy normally.

Detailed implementation manners

[0019] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and that changes may be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example may omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples may be combined in other examples.

[0020] As Figures 1 - 12 shown, a storage and deployment mechanism for a pod honeycomb telescopic rod is used to store and deploy the pod honeycomb telescopic rod 10. The pod honeycomb telescopic rod 10 includes a main body part 101 and connecting parts 102 located on both sides of the main body part 101. The storage and deployment mechanism for the pod honeycomb telescopic rod includes: a bracket 1, a storage and deployment assembly 2, a pre-tightening assembly 3, and an auxiliary storage and deployment assembly 4. Among them, the bracket 1 mainly plays a role in installation and support. The storage and deployment assembly 2 is mainly used to store and deploy the pod honeycomb telescopic rod 10 according to the actual working conditions. The pre-tightening assembly 3 is mainly used to maintain the structural stability during the storage and deployment of the pod honeycomb telescopic rod 10. The auxiliary storage and deployment assembly 4 is mainly used to assist the pod honeycomb telescopic rod 10 in performing storage and deployment actions.

[0021] Specifically, as Figure 1 shown, the bracket 1 includes a first side plate 11 and a second side plate 12. The first side plate 11 and the second side plate 12 have the same structure and are arranged in parallel at intervals. The bracket 1 further includes a bottom plate 14 and a top plate 13. The bottom plate 14 is fixedly connected to the bottoms of the first side plate 11 and the second side plate 12 for connecting the bottoms of the first side plate 11 and the second side plate 12. The top plate 13 is fixedly connected to the tops of the first side plate 11 and the second side plate 12 for connecting the tops of the first side plate 11 and the second side plate 12. In this way, the structure of the bracket 1 can be made more stable, so that the bracket 1 can better play a supporting role, and a receiving space can be formed between the first side plate 11, the second side plate 12, the top plate 13 and the bottom plate 14 for installing other corresponding components.

[0022] As Figure 4 and Figure 7 shown, the storage and deployment assembly 2 includes a drum 21, a pressing plate 22 and a driving assembly 23. Both ends of the drum 21 are respectively rotatably connected to the first side plate 11 and the second side plate 12, and are mainly used to realize the storage and deployment of the pod honeycomb extension rod 10. The pressing plate 22 is mainly used to press one end of the pod honeycomb extension rod 10 against the drum 21, so that when the drum 21 rotates in different directions, the pod honeycomb extension rod 10 will be stored or deployed.

[0023] Specifically, as Figure 4 and Figure 7 shown, the drum 21 includes: a cylinder body 211, a connecting shaft 212, a first sealing plate 213 with a cylindrical structure and a second sealing plate 214 with a cylindrical structure. The first sealing plate 213 and the second sealing plate 214 are respectively fixedly connected to both sides of the cylinder body 211. The connecting shaft 212 is coaxially arranged with the cylinder body 211, and both ends of the connecting shaft 212 respectively pass through the first sealing plate 213 and the second sealing plate 214 and are rotatably connected to the first side plate 11 and the second side plate 12. The radii of the first sealing plate 213 and the second sealing plate 214 are greater than the radius of the cylinder body 211. It should be noted that the cylinder body 211 is fixedly connected to the connecting shaft 212 through the first sealing plate 213 and the second sealing plate 214, and both ends of the connecting shaft 212 are respectively rotatably connected to the first side plate 11 and the second side plate 12, so that the cylinder body 211 can rotate relative to the first side plate 11 and the second side plate 12 to realize the storage and deployment of the pod honeycomb extension rod 10.

[0024] It should be noted that the storage state of the pod honeycomb telescopic rod 10 is to flatten one end of the pod honeycomb telescopic rod 10 first, and then the pressing plate 22 fixes the flattened end on the cylinder body 211. Threaded holes are provided on both the pressing plate 22 and the cylinder body 211. An installation hole 103 is opened at the flattened end of the pod honeycomb telescopic rod 10. The pressing plate 22, the flattened end of the pod honeycomb telescopic rod 10, and the cylinder body 211 can be fixedly connected by countersunk head screws.

[0025] In addition, the radii of the first sealing plate 213 and the second sealing plate 214 are greater than the radius of the cylinder body 211. In this way, the first sealing plate 213 and the second sealing plate 214 can be used to limit the pod honeycomb telescopic rod 10 wound around the cylinder body 211 in the axial direction of the cylinder body 211, reducing the situation that the pod honeycomb telescopic rod 10 deviates or detaches from the cylinder body 211 during the winding storage and unfolding processes.

[0026] As shown in Figure 4 and Figures 7 - 10 shown, the driving assembly 23 is mainly used to drive the roller 21 to rotate, so as to realize the automatic winding storage and unfolding of the pod honeycomb telescopic rod 10. The driving assembly 23 includes a motor 231, a gear ring 232, an intermediate gear 233, and a driving gear 234. The gear ring 232 is fixedly connected to the first sealing plate 213 and is concentric with the first sealing plate 213. Both the intermediate gear 233 and the driving gear 234 are rotatably connected to the first side plate 11, and the intermediate gear 233 is simultaneously adapted to the driving gear 234 and the gear ring 232. The motor 231 is arranged on the first side plate 11 and its output end is fixedly connected to the driving gear 234. It should be noted that both the intermediate gear 233 and the driving gear 234 are rotatably connected to the first side plate 11 through shafts, and the output end of the motor 231 is fixedly connected to the driving gear 234 through a coupling.

[0027] During use, start the motor 231. The rotation of the motor 231 can drive the driving gear 234 to rotate. The rotation of the driving gear 234 can drive the intermediate gear 233 to rotate. The rotation of the intermediate gear 233 will drive the gear ring 232 to rotate. Since the gear ring 232 is fixedly connected to the first sealing plate 213, the rotation of the gear ring 232 will drive the cylinder body 211 to rotate. Furthermore, the storage and unfolding of the cylinder body 211 for the pod honeycomb telescopic rod 10 can be realized by controlling the rotation direction of the motor 231. The control of the motor 231 is an existing technology, and the motor 231 can be controlled by a controller.

[0028] As an alternative embodiment, as shown in Figure 8As shown, a cut with a cross-sectional shape of a minor arc bow is provided on the surface of the cylinder body 211 along its axial direction. The cross-sectional shape of the pressing plate 22 along its length direction is also a minor arc bow. Moreover, when the pressing plate 22 presses one end of the pod honeycomb extension rod 10, the distance from the pressing plate 22 to the axis of the cylinder body 211 is equal to the radius of the cylinder body 211. That is to say, when the pressing plate 22 presses the pod honeycomb extension rod 10, it is on the same circle as the outer wall of the cylinder body 211, which can make the pressing plate 22 closer to the cylinder body 211 and is beneficial for the pod honeycomb extension rod 10 to wind better on the cylinder body 211.

[0029] In addition, as Figure 6 and Figure 9 shown, the pre-tightening assembly 3 includes a first transmission assembly 36 and a pre-tightening frame 31 arranged on one side of the drum 21 in the receiving direction. It should be noted that the receiving direction of the drum 21 is the rotational direction in which the drum 21 receives the pod honeycomb extension rod 10. For example, when the drum 21 rotates clockwise and the pod honeycomb extension rod 10 winds around the drum 21 from the upper surface of the drum 21, the pre-tightening frame 31 can be arranged on the right side of the drum 21. This can avoid interference between the pre-tightening frame 31 and the pod honeycomb extension rod 10 in the unfolded state.

[0030] Specifically, as Figures 7 - 9 shown, the pre-tightening frame 31 includes a guiding portion 311 and a mounting portion 312. The mounting portion 312 is connected to the side of the guiding portion 311 away from the cylinder body 211. The cross-sectional shape of the guiding portion 311 along the axial direction of the cylinder body 211 is arc-shaped, and the guiding portion 311 is concentrically arranged with the cylinder body 211. The pre-tightening rod 34 is slidably connected to the guiding portion 311. The structural design of the guiding portion 311 can make the shape of the guiding portion 311 more suitable for the shape of the cylinder body 211 and can better guide the pre-tightening rod 34. Two groups of support frames 313 are symmetrically arranged on the upper and lower sides of the mounting portion 312, that is, a total of four support frames 313. A sleeve 32 with an axis pointing to the axis of the drum 21 is fixedly connected to each support frame 313. The pre-tightening rod 34 is slidably connected inside the sleeve 32. The free end of the pre-tightening rod 34 extends out of the sleeve and approaches the cylinder body 211 through the guiding portion 311. An elastic member 33 is arranged between the pre-tightening rod 34 and the bottom wall of the sleeve 32. The elastic member 33 can be a spring, and of course, it can also be other suitable components.

[0031] A pressing wheel 35 with a surface tangent to the surface of the drum 21 is rotatably connected between two pre-tightening rods 34 on the same side, that is, a pressing wheel 35 is rotatably connected between the free ends of the two upper pre-tightening rods 34 and between the free ends of the two lower pre-tightening rods 34. The pressing wheel 35 is in contact with the surface of the drum 21 in the initial state, specifically tangent to the surface of the cylinder body 211. In this way, during the winding process of the pod honeycomb extension rod 10, the pressing wheel 35 always has a pressure to squeeze the pod honeycomb extension rod 10 towards the cylinder body 211, so that the winding of the pod honeycomb extension rod 10 on the cylinder body 211 can be made more compact, reducing the gap between each layer during the winding process of the pod honeycomb extension rod 10, which is beneficial to the protection of the pod honeycomb extension rod 10. In addition, as the winding thickness of the pod honeycomb extension rod 10 on the cylinder body 211 increases, the potential energy stored in the pod honeycomb extension rod 10 itself also increases. At this time, the pod honeycomb extension rod 10 will push the pre-tightening rod 34 to compress the elastic member 33 in the sleeve 32, and the elastic force of the elastic member 33 will also increase accordingly, so that the pre-tightening rod 34 can be pushed to exert a greater pressure on the pod honeycomb extension rod 10, thus making the winding of the pod honeycomb extension rod 10 on the cylinder body 211 more compact.

[0032] In addition, as shown in Figure 4 , Figure 6 and Figure 10 , the first transmission assembly 36 is used to transfer the kinetic energy of the drive assembly 23 to the pre-tightening frame 31 to drive the pre-tightening frame 31 to move. Specifically, the first transmission assembly 36 includes a first fixed frame 361, a second fixed frame 362, a first gear 363, a second gear 364, a third gear 365, a first transmission shaft 366, a screw 367, a nut seat 368, a first bevel gear 369 and a second bevel gear 370. Among them, the first fixed frame 361 and the second fixed frame 362 are both fixedly connected between the first side plate 11 and the second side plate 12, and the first fixed frame 361 can be arranged below the pre-tightening frame 31. Both the first fixed frame 361 and the second fixed frame 362 can be in the shape of a cuboid.

[0033] The second fixing frame 362 is arranged on the side of the first fixing frame 361 away from the roller 21. One end of the screw 367 is rotatably connected to the first fixing frame 361, and the other end of the screw 367 passes through the second fixing frame 362 and is fixedly connected to the first bevel gear 369. The nut seat 368 is threadedly connected to the screw 367, and the nut seat 368 is fixedly connected to the bottom of the mounting portion 312. The first transmission shaft 366, the first gear 363, and the second gear 364 are all rotatably connected to the first side plate 11. The third gear 365 and the second bevel gear 370 are both fixedly connected to the first transmission shaft 366, and moreover, the second bevel gear 370 is adapted to the first bevel gear 369, the first gear 363 is adapted to the gear ring 232, and the second gear 364 is simultaneously adapted to the first gear 363 and the third gear 365. It should be noted that both the first gear 363 and the second gear 364 are rotatably connected to the first side plate 11 through shafts.

[0034] During the process of the motor 231 driving the roller 21 to rotate, the gear ring 232 will drive the first gear 363 to rotate. The rotation of the first gear 363 can drive the first transmission shaft 366 to rotate through the transmission of the second gear 364 and the third gear 365 in sequence. The rotation of the first transmission shaft 366 will drive the second bevel gear 370 to rotate. The rotation of the second bevel gear 370 can drive the screw 367 to rotate through the cooperation with the first bevel gear 369. The rotation of the screw 367 can further drive the nut seat 368 to move along the axial direction of the screw 367, so as to drive the pre-tightening frame 31 to move along the axial direction of the screw 367. It should be noted that through the design of the thread on the screw 367, when the cylinder body 211 winds the pod honeycomb extension rod 10, the pre-tightening frame 31 moves towards the side away from the cylinder body 211, and when the cylinder body 211 unfolds the pod honeycomb extension rod 10, the pre-tightening frame 31 moves towards the side close to the cylinder body 211. In this way, the pressure of the pressing wheel 35 on the pod honeycomb extension rod 10 can always be maintained within a suitable range, and there will be no excessive pressure difference of the pressing wheel 35 on the pod honeycomb extension rod 10 in the two cases of the initial winding and the completion of winding of the pod honeycomb extension rod 10. It can not only make the pod honeycomb extension rod 10 tightly wound on the cylinder body 211, but also facilitate the unfolding of the pod honeycomb extension rod 10 from the cylinder body 211, and can also achieve the protection of the pod honeycomb extension rod 10.

[0035] As an alternative embodiment, as Figure 2 shown, a fourth fixing frame 9 is fixedly connected to the first side plate 11, and the middle part of the first transmission shaft 366 is rotatably connected to the fourth fixing frame 9. In this way, the fourth fixing frame 9 can be used to support the first transmission shaft 366, so that the first transmission shaft 366 can work better.

[0036] As an alternative embodiment, as Figure 6As shown in the figure, the telescopic rod storage and deployment mechanism of the pod honeycomb further includes a third fixing bracket 5, a guide plate 6 and a guide rod 7. The two ends of the third fixing bracket 5 are respectively fixedly connected to the first side plate 11 and the second side plate 12, and the third fixing bracket 5 can also be of a cuboid structure. The guide plate 6 is fixedly connected to the upper side wall of the installation part 312, and the two ends of the guide rod 7 are respectively fixedly connected to the second fixing bracket 362 and the third fixing bracket 5. The guide plate 6 is located between the second fixing bracket 362 and the third fixing bracket 5, and the guide plate 6 is slidably connected to the guide rod 7. Among them, the third fixing bracket 5 can be arranged above the pre-tightening bracket 31. Through the sliding connection between the guide plate 6 and the guide rod 7, the pre-tightening bracket 31 can move more stably, so that the pressing wheel 35 can better press the telescopic rod 10 of the pod honeycomb against the cylinder body 211.

[0037] In addition, as Figure 1 and Figure 5 shown, the auxiliary retracting and deploying assembly 4 includes a second transmission assembly 43, two guide rails 41 and two driving wheels 42. The two guide rails 41 are respectively fixedly connected to the first side plate 11 and the second side plate 12, and are both located on one side of the unfolding direction of the roller 21, and are used to guide the two side connecting parts 102. It should be noted that the structure of the guide rail 41 can be a C-shaped structure, and the openings of the two side guide rails 41 are arranged opposite to each other, that is, the opening direction of one side guide rail 41 is set to face the other side guide rail 41. The connecting parts 102 on both sides of the telescopic rod 10 of the pod honeycomb are respectively slidably connected in the openings of the two side guide rails 41. In this way, the guide rail 41 can be used to orient and limit the telescopic rod 10 of the pod honeycomb, so that the movement of the telescopic rod 10 of the pod honeycomb is more stable.

[0038] The guide rail 41 is provided with through holes 411 communicating with the connecting part 102 in the vertical direction. The two driving wheels 42 correspond to the two connecting parts 102 one by one, and the surface of the driving wheel 42 contacts the corresponding connecting part 102 through the through hole 411. Specifically, the through hole 411 can be opened at the bottom of the guide rail 41, and the through hole 411 communicates with the opening in the guide rail 41. The surface of the driving wheel 42 contacts the corresponding connecting part 102 through the through hole 411. That is to say, there is friction between the driving wheel 42 and the connecting part 102. In this way, during the rotation of the driving wheel 42, due to the friction force, there is a tendency to drive the connecting part 102 to move. By changing the rotation direction of the driving wheel 42, the telescopic rod 10 of the pod honeycomb can be helped to be retracted and deployed.

[0039] As Figure 1 、 Figures 3 - 5As shown, the second transmission assembly 43 is used to transfer the kinetic energy of the drive assembly 23 to the two drive wheels 42. Specifically, the second transmission assembly 43 includes a second transmission shaft 431 and two third transmission shafts 432. The two third transmission shafts 432 are respectively rotatably connected to the first side plate 11 and the second side plate 12. The axes of the two third transmission shafts 432 are parallel to the axis of the cylinder body 211. The two drive wheels 42 are respectively fixedly connected to the two third transmission shafts 432. The two ends of the second transmission shaft 431 are respectively rotatably connected to the first side plate 11 and the second side plate 12. There is a first pulley assembly 433 drivingly connected between the output end of the motor 231 and the second transmission shaft 431. The output end of the motor 231 is the output shaft of the motor 231. There is a second pulley assembly 434 drivingly connected between the second transmission shaft 431 and the two third transmission shafts 432. It should be noted that both the first pulley assembly 433 and the second pulley assembly 434 are prior arts and are each composed of two pulleys and a belt.

[0040] During use, when the motor 231 drives the drum 21 to rotate, the output end of the motor 231 will drive the second transmission shaft 431 to rotate through the first pulley assembly 433. The rotation of the second transmission shaft 431 will drive the two third transmission shafts 432 to rotate simultaneously through the transmission of the two second pulley assemblies 434, and then drive the two drive wheels 42 to rotate. Since the connecting portion 102 of the drive wheel 42 and the pod honeycomb extension rod 10 is in frictional contact, and the rotation direction of the drive wheel 42 is the same as that of the drum 21, when the drum 21 drives the pod honeycomb extension rod 10 to be retracted or deployed, the drive wheel 42 can play an auxiliary role, which is beneficial to the retraction and deployment of the pod honeycomb extension rod 10, and can reduce the situation of the pod honeycomb extension rod 10 slipping relative to the drum 21 during the deployment process, so that the retraction and deployment process of the pod honeycomb extension rod 10 can be more smooth.

[0041] As an alternative embodiment, the pod honeycomb extension rod retraction and deployment mechanism further includes a guide frame 8. The guide frame 8 is arranged between the guide rail 41 and the drum 21. A guide hole 81 with a cross-sectional shape identical to the outer contour cross-sectional shape of the pod honeycomb extension rod 10 in the fully deployed state is provided on the guide frame 8. The guide frame 8 mainly plays a guiding and supporting role. It should be noted that when the pod honeycomb extension rod 10 is fully retracted, a part of its free end is still inside the guide frame 8. In this way, the guide frame 8 can be used to maintain the state of the pod honeycomb extension rod 10 in the fully deployed state, and can support and guide the pod honeycomb extension rod 10 during the retraction and deployment process, so that the movement of the pod honeycomb extension rod 10 can be more stable.

[0042] As an alternative embodiment, the guide frame 8 is disposed close to the guide rail 41, and the guide hole 81 communicates with the guide rail 41. Since a part of the free end of the pod honeycomb telescopic rod 10 is still inside the guide frame 8 when the pod honeycomb telescopic rod 10 is fully retracted, during the unfolding process of the pod honeycomb telescopic rod 10, the connecting parts 102 on both sides of the pod honeycomb telescopic rod 10 can directly enter the inside of the guide rail 41 from the guide hole 81, so that the unfolding of the pod honeycomb telescopic rod 10 can be smoother, which is beneficial to the smooth unfolding of the pod honeycomb telescopic rod 10.

[0043] The above embodiment has been described, but this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
