Description

Technical Field

[0001] This invention relates to the field of shading devices, and in particular to an integrated shading device for a lunar surface rover with a high expansion-to-contraction ratio. Background Technology

[0002] With the advancement of aerospace technology and the ongoing exploration and development of the moon, manned lunar rovers will enable astronauts to move quickly and efficiently on the lunar surface, providing significant convenience for future manned lunar scientific expeditions. However, direct sunlight on the moon can cause considerable damage to the rover's seats, control panel, and other equipment and components. Furthermore, sunlight can affect astronauts' driving skills, creating safety hazards. Therefore, to address these issues, a sunshade device suitable for lunar rovers is proposed. Summary of the Invention

[0003] The present invention aims to provide an integrated sunshade device for a lunar rover with a high expansion-to-contraction ratio, which solves the problem of direct sunlight on the surface of the manned lunar rover affecting the astronauts' driving and accelerating the aging of onboard components.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: An integrated light-shielding device for a high expansion-to-recovery ratio lunar surface rover, comprising:

[0005] Two lifting bases are symmetrically arranged on the lunar rover;

[0006] There are four lifting support rods, with each pair of lifting support rods forming a group. The two lifting support rods in each group are rotatably connected together by a lifting hinge, and any lifting support rod is rotatably connected to the corresponding lifting base.

[0007] A lifting top support is provided, which is connected to the free ends of two sets of lifting support rods.

[0008] Two horizontal mounting supports are respectively installed on the corresponding lifting top supports;

[0009] Four transverse support rods, with each pair of transverse support rods forming a group. The two transverse support rods in each group are rotatably connected together by transverse hinges, and any transverse support rod is rotatably connected to the corresponding transverse mounting bracket.

[0010] A transverse front guard, which is connected between the free ends of two sets of transverse support rods;

[0011] A sunshade cloth, which is connected between the transverse front windshield and the transverse mounting bracket.

[0012] Furthermore, each of the lifting bases and the corresponding lifting top support is provided with a mutually cooperating lifting locking block, and a lifting locking pin is provided between the two lifting locking blocks.

[0013] Furthermore, a crossbeam connects the two lifting top supports; symmetrical horizontal locking blocks are provided on both the horizontal front guard and the crossbeam, and a horizontal locking pin is provided through both horizontal locking blocks.

[0014] Furthermore, both the lifting hinge and the lateral hinge are electric hinges, and the electric hinges are electrically connected to the lunar rover's control system.

[0015] Furthermore, the crossbeam is also equipped with a storage box, and a rotating shaft is rotatably connected inside the storage box. A coil spring is connected between the rotating shaft and the storage box. One end of the sunshade cloth is connected to the rotating shaft, and the other end of the sunshade cloth is connected to the horizontal front windshield.

[0016] Furthermore, when the sunshade device is in the retracted state, a foam pad is filled between the lunar rover and the horizontal mounting support.

[0017] Compared with existing technologies, the beneficial effects of this solution are:

[0018] 1. The space occupied by this solution differs greatly when it is unfolded and folded. The height ratio of the unfolded to folded device is 10:1. The horizontal unfolding device can also achieve a ratio of 16:1 when it is horizontally unfolded to folded. By adjusting some structural parameters in this solution, the unfolding-folding ratio can be further improved. The high unfolding-folding ratio proves that the sunshade device occupies as little space as possible when folded, making it easy to carry. At the same time, it can provide a large sunshade area when unfolded, thus better meeting the functional requirements.

[0019] 2. This solution only requires removing the locking pin during deployment, and is controlled by commands from the lunar rover's control system, with actuation via an electric hinge. Therefore, the deployment of this invention has advantages such as simplicity and convenience.

[0020] 3. This solution effectively constrains each component in the folded state through a locking device, increasing the stability of the system when folded, thereby enabling the system to withstand overload and vibration environments during transportation.

[0021] 4. This solution itself includes a lifting support structure, which can be directly installed on the body of the lunar rover without the need for additional support structures. Attached Figure Description

[0031] Example

[0032] like Figures 1 to 7 As shown, an integrated shading device for a high deployment-to-recovery ratio lunar rover includes:

[0033] Two lifting bases 8 are symmetrically and fixedly connected to the lunar rover. In this embodiment, a first lifting locking block 1 is fixedly connected to one side of each lifting base 8. The first lifting locking block 1 is U-shaped.

[0034] There are two first lifting support rods 10 and two second lifting support rods 12. Each first lifting support rod 10 and the second lifting support rod 12 form a group. The first lifting support rods 10 and the second lifting support rod 12 in each group are rotatably connected together by the second lifting hinge 11. The first lifting support rod 10 is rotatably connected to the corresponding lifting base 8 by the first lifting hinge 9.

[0035] A lifting top support 14 is rotatably connected to the top of two second lifting support rods 12 via a third lifting hinge 13. In this embodiment, a second lifting locking block 2, which cooperates with the first lifting locking block 1, is fixedly connected to the side wall of each lifting top support 14. The second lifting locking block 2 is a convex shape that cooperates with the first lifting locking block 1. The first lifting locking block 1 and the second lifting locking block 2 have interconnected first limiting holes at the same location, and a lifting locking pin 3 passes through all the first limiting holes. When the first lifting locking block 1 and the second lifting locking block 2 cooperate, the lifting locking pin 3 can mechanically lock the first lifting locking block 1 and the second lifting locking block 2. A crossbeam 15 is connected between the two lifting top supports 14, and a second horizontal locking block 5 is fixedly connected to the left and right sides of the front side wall of the crossbeam 15.

[0036] Two horizontal mounting supports 17 are fixedly connected to the corresponding lifting top supports 14.

[0037] Two first transverse support rods 19 and two second transverse support rods 21 are provided. Each set of first transverse support rods 19 and second transverse support rods 21 is rotatably connected by a second transverse hinge 20, and the first transverse support rod 19 is rotatably connected to the corresponding transverse mounting bracket 17 by a first transverse hinge 18. When the transverse device is folded, the transverse locking pin 6 passes through the first transverse locking block 4 and the second transverse locking block 5, completing the mechanical limiting of the first transverse locking block 4 and the second transverse locking block 5.

[0038] A transverse front guard 23 is rotatably connected between the free ends of two second transverse support rods 21 via a third transverse hinge 22. In this embodiment, a first transverse locking block 4 is fixedly connected to the front side wall of the transverse front guard 23. Each first transverse locking block 4 and its corresponding second transverse locking block 5 are provided with a transverse locking pin 6. A second limiting hole for the transverse locking pin 6 to pass through is provided at the same position on the first transverse locking block 4 and the corresponding second transverse locking block 5.

[0039] A sunshade fabric 24 is connected between the horizontal front fender 23 and the pivot 26. In this embodiment, the sunshade fabric 24 is covered by a storage box 16 with an opening on one side. The storage box 16 is installed above the crossbeam 15. Mounting bases 25 are provided on both sides inside the storage box 16. A hollow pivot 26 is rotatably connected between the two mounting bases 25. A coil spring 27 is connected between the end of the pivot 26 and the mounting base 25. The inner end of the coil spring 27 is fixed to the mounting base 25 through a groove formed by the protrusion in the middle of the mounting base 25, and the outer end of the coil spring 27 is fixed to the pivot 26. One side of the sunshade fabric 24 is adhered and fixed to the surface of the pivot 26 and is completely rolled up on the pivot 26. One side of the sunshade fabric 24 is adhered and connected to the horizontal front fender 23, and the other side of the sunshade fabric 24 is adhered and connected to the pivot 26. When the pivot 26 rotates relative to the mounting base 25, the coil spring 27 deforms, accumulating elastic potential energy to tension the sunshade cloth 24. During the unfolding process of the horizontal device, the sunshade cloth 24 is pulled out of the storage box 16 with the help of the horizontal front guard 23. The coil spring 27 deforms. During the folding process of the horizontal device, the deformation of the coil spring 27 returns to normal, driving the pivot 26 to rotate and retracting the sunshade cloth 24.

[0040] In this embodiment, when the sunshade device is in the retracted state, a foam pad is filled between the lunar rover and the horizontal mounting bracket. When the sunshade device is in the folded state, the foam pad 7 is filled between the manned lunar rover and the first lifting support rod 10 of the sunshade device, providing support for the first lifting support rod 10 and preventing structural damage caused by vibration during transportation.

[0041] In this embodiment, the first lifting hinge 9, the second lifting hinge 11, the third lifting hinge 13, the first lateral hinge 18, the second lateral hinge 20, and the third lateral hinge 22 are all motor-driven joints. The first lifting hinge 9, the second lifting hinge 11, the third lifting hinge 13, the first lateral hinge 18, the second lateral hinge 20, and the third lateral hinge 22 are all electrically connected to the lunar rover's control system, so that the lunar rover's control system can be used to drive each hinge to complete the self-locking of the target position.

[0042] The specific work process of this plan is as follows:

[0043] The sunshade is folded during transport and unfolds after the lunar rover is deployed on the lunar surface. First, the lifting locking pin 3 and the lateral locking pin 6 are removed to unlock the mechanical limits of the sunshade. Astronauts then board the lunar rover and use its control system to rotate the various hinges, thereby unfolding the sunshade via the lifting and lateral support rods.

[0044] During deployment, the first lifting hinge 9, the second lifting hinge 11, and the third lifting hinge 13 are first rotated at a controlled angle to vertically raise and lock the first lifting support rod 10 and the second lifting support rod 12. Then, the first horizontal extension hinge 18, the second horizontal extension hinge 20, and the third horizontal extension hinge 22 are rotated to extend the horizontal extension front guard 23 outward, while simultaneously pulling the sunshade 24 out of the storage box 16. When the first horizontal extension support rod 19 and the second horizontal extension support rod 21 are straightened and reach the target position, the first horizontal extension hinge 18, the second horizontal extension hinge 20, and the third horizontal extension hinge 22 are locked, completing the opening of the sunshade 24. At this point, the sunshade device is fully opened, realizing its sunshade function. When not in use, the sunshade device can be folded by controlling the individual hinges to reset through the lunar rover's control system.

[0045] The above are merely embodiments of the present invention, and common knowledge such as specific structures and / or characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
