Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The purpose of this invention is to provide a lunar dust protection device and a lunar robot to solve the problems existing in the prior art and improve the reliability of dust protection.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] This embodiment provides a lunar dust protection device for a lunar robot. Please refer to [link / reference]. Figures 1-4 It includes a flexible substrate layer 1, a microstructure dust-guiding layer 2, and an electrode functional layer 3; the flexible substrate layer 1 is used to be surface-fitted to the surface to be protected; the microstructure dust-guiding layer 2 is disposed on the side of the flexible substrate layer 1 away from the surface to be protected, and the microstructure dust-guiding layer 2 is used to electrostatically shield and guide the desorption of dust particles; the electrode functional layer 3 is disposed on the side of the flexible substrate layer 1 away from the surface to be protected, and the electrode functional layer 3 can apply an alternating electric field to the dust particles to cause the charged dust particles to migrate.

[0030] The flexible base layer 1 can be directly attached to the surface of the robot body, providing mechanical compliance and radiation resistance to the entire skin structure. It can also adapt to various curved surfaces and flexible joints of the robot. The microstructure dust-guiding layer 2 is distributed on the surface of the flexible base layer 1. It uses the microstructure surface to electrostatically shield and guide the desorption of dust particles, preventing the dust particles from accumulating randomly on the surface. In addition, the electrode functional layer 3 applies an alternating electric field to charge the dust particles and generate oscillations, which destroys the initial adsorption state and performs electro-oscillating dust removal. This works in conjunction with the microstructure dust-guiding layer 2 to achieve dust prevention and dust removal, improving the reliability of dust prevention.

[0031] In the optional embodiments of this example, more preferably, the microstructure dust-guiding layer 2 includes a trench array and a protrusion array 21. The trench array is formed on the side of the flexible substrate layer 1 away from the surface to be protected, and the protrusion array 21 is distributed on the surface of the trench array and / or the surface of the flexible substrate layer 1 in the gaps inside the trench array. The electrode functional layer 3 is disposed on the surface of the flexible substrate layer 1 in the gaps inside the trench array, and the electrode functional layer 3 enables charged dust particles to migrate to the trench array.

[0032] Among them, the microstructure dust-guiding layer 2 is constructed on the surface of the flexible substrate layer 1, and has a composite surface structure of groove array and protrusion array 21. The protrusion array 21 is distributed in the planar area of ​​the surface of the flexible substrate layer 1 between the inner wall of the groove array and the interior of the groove array. The groove array and the protrusion array 21 work together to achieve electrostatic shielding and guided desorption. The protrusion array 21 can destroy the electrostatic adsorption force between dust particles and the surface of the flexible substrate layer 1. The height difference formed by the groove array and the protrusion array 21 can guide the dust particles to slide or be thrown away along the groove array, avoiding the irregular accumulation of dust particles on the surface of the flexible substrate layer 1. In conjunction with the electrode functional layer 3, an alternating electric field is applied to form a two-dimensional electric field distribution, which causes the charged dust particles to migrate, realizing electro-oscillating dust removal.

[0033] In the optional scheme of this embodiment, more preferably, the trench array includes multiple dust guide grooves arranged side by side, the length direction of each dust guide groove is perpendicular to the side-by-side direction, and both ends of the length direction of each dust guide groove extend to the edge of the flexible substrate layer 1; the protrusion array 21 is distributed on the surface of each dust guide groove and / or the surface of the flexible substrate layer 1 between adjacent dust guide grooves; the electrode functional layer 3 is disposed on the surface of the flexible substrate layer 1 between adjacent dust guide grooves.

[0034] By setting multiple parallel dust guide grooves extending to the edge of the flexible substrate 1, the dust particles on the surface of the flexible substrate 1 can be guided in multiple ways and detached from the edge of the flexible substrate 1. In conjunction with the protrusion array 21 and the electrode functional layer 3, the electrostatic adsorption force between the dust particles and the surface of the flexible substrate 1 is broken, and the dust particles are guided to slide or be thrown away along the dust guide grooves, avoiding the irregular accumulation of dust particles on the surface of the flexible substrate 1. In conjunction with the electrode functional layer 3, an alternating electric field is applied to form a two-dimensional electric field distribution, which causes the charged dust particles to migrate, thereby realizing electro-oscillating dust removal.

[0035] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figure 2 The protrusion array 21 includes a plurality of arrayed needle-shaped protrusions 22, which are disposed on the surface of the corresponding dust guide groove and / or the surface of the flexible base layer 1 between adjacent dust guide grooves.

[0036] Among them, multiple arrayed needle-like protrusions 22 are distributed on the surface of each dust guide groove and the surface of the flexible base layer 1 between adjacent dust guide grooves, which fully destroys the electrostatic adsorption force between dust particles and the surface of the flexible base layer 1, forming an electrostatic shield.

[0037] In the optional scheme of this embodiment, it is more preferred that the width, depth and spacing between adjacent dust guide grooves are all set at the micrometer level, and the size of each needle-shaped protrusion 22 is set at the nanometer level.

[0038] That is, by setting micron-level dust guide grooves and nano-level needle-like protrusions 22, the needle-like protrusions 22 can be distributed in the dust guide grooves and between adjacent dust guide grooves; specifically, the specific distribution size and position of the dust guide grooves and needle-like protrusions 22 can be determined according to actual design requirements.

[0039] In an optional embodiment, more preferably, the electrode functional layer 3 includes a plurality of arrayed electrode units 31, which are arrayed on the surface of the flexible substrate layer 1 between several dust guide grooves; each electrode unit 31 can apply an alternating electric field to the dust particles to cause the charged dust particles to migrate to the adjacent dust guide groove.

[0040] In this method, by avoiding affecting the sliding path of dust particles in the dust guide channel on the surface of the flexible base layer 1 between adjacent dust guide channels, the deposited dust particles can be migrated to the adjacent dust guide channel under the action of an alternating electric field, and then the dust particles can be guided and detached through the dust guide channel.

[0041] Further, please see Figure 3 Each electrode unit 31 is configured as an I-shape, and multiple electrode units 31 are arranged in a matrix on the entire flexible substrate layer 1. Each I-shaped electrode unit 31 corresponds to a micro-nano dust-guiding area, with the middle two sides of the I-shaped electrode unit 31 facing the dust-guiding groove. Figure 3 The electric field distribution range after the electrode is energized is marked by electric field lines, driving charged dust particles into adjacent dust guide grooves. An alternating electric field is used to directionally drive the charged dust particles within the dust guide groove region. Furthermore, the length direction of the dust guide groove forms an angle of 30° to 60° with the main direction of dust particle migration. The main direction of dust particle migration refers to the main direction of movement of charged dust particles under the action of the electric field force after the alternating electric field is applied to the electrode unit 31 (e.g., ...). Figure 3 As indicated by the middle arrow, this direction forms an angle of 30° to 60° with the length of the dust guide channel. This avoids the "slippage inertia" of dust particles caused by the electric field force being completely parallel to the guiding force of the dust guide channel. The oblique electric field force pushes the dust particles to generate a component force along the dust guide channel, improving migration efficiency. The angle range of 30° to 60° can balance "migration speed" and "guiding accuracy". It prevents the dust particles from deviating from the dust guide channel due to the angle being too small, and also prevents the electric field force from being wasted due to the angle being too large. This ensures that the dust particles enter the dust guide channel efficiently and detach along the edge of the channel.

[0042] In the optional scheme of this embodiment, more preferably, the lunar dust protection device for the lunar robot provided in this embodiment also includes a control module, which is electrically connected to the electrode functional layer 3 and can apply electrical signals to the electrode functional layer 3.

[0043] The embedded electronic control module is integrated into the robot's internal control compartment and connected to the skin electrode functional layer 3 via flexible wiring. Multiple electrode units 31 are connected to the control module in parallel via flexible wiring. The flexible wiring is located on the edge region of the flexible substrate layer 1 away from the surface to be protected (along the length or width of the flexible substrate layer 1), with a wiring width of 50μm. It does not occupy the functional area of ​​the dust guide groove and the protrusion array 21, thus avoiding affecting the guidance and desorption of dust particles. The embedded flexible electronic module can be an STM32L476RG, which includes a flexible control circuit, a power management unit, and a sensor signal processing unit. It can control the electric field frequency, amplitude, and excitation period of the electrode functional layer 3 in real time. The system adaptively adjusts the drive power according to the dust particle density detected by the sensor to achieve optimal energy consumption for active dust prevention control.

[0044] In the optional embodiments of this example, more preferably, the lunar dust protection device for the lunar robot provided in this example further includes a monitoring component. The monitoring component is communicatively connected to the control module and is used to monitor and transmit dust particle concentration and / or particle size information to the control module.

[0045] The monitoring component uses an optical dust sensor, which is evenly distributed on the skin edges of areas with high dust adhesion risk, such as the robot's flexible joints and sensor transparent windows. The sensor probe can monitor the concentration and particle size distribution of dust particles in the area in real time. The control module adaptively adjusts the frequency and amplitude of the alternating electric field according to the dust particle density detected by the sensor to achieve adaptive energy consumption control.

[0046] In the optional solutions of this embodiment, more preferably, the lunar dust protection device for the lunar robot provided in this embodiment further includes an anti-adhesion layer 4, which is disposed on the surface of the electrode functional layer 3 and the microstructure dust guiding layer 2; and the anti-adhesion layer 4, the electrode functional layer 3 and the flexible substrate layer 1 are all made of transparent material.

[0047] In this process, an anti-adhesion layer 4 is set to cover the surface of the electrode functional layer 3 and the microstructure dust-guiding layer 2, which reduces dust particle deposition and prevents the electrode functional layer 3 and the microstructure dust-guiding layer 2 from being directly exposed to the complex environment of the lunar surface, thereby improving their lifespan.

[0048] Furthermore, the anti-adhesion layer 4, the electrode functional layer 3, and the flexible substrate layer 1 are all made of transparent materials, so that the entire lunar dust protection device for the lunar robot can be applied to the transparent window to be protected; specifically, the anti-adhesion layer 4 is made of a low surface energy material such as FEP film, the flexible substrate layer 1 is made of flexible polyimide or fluorinated polymer material, and the electrode functional layer 3 is made of transparent ITO conductive film material.

[0049] The protective principle of the lunar dust protection device for the lunar robot provided in this embodiment is as follows: Figure 5 As shown, the dust particle desorption process is as follows: The first step is that the dust particles are charged and oscillate under the action of the alternating electric field, which destroys the initial adsorption state of the dust particles and causes the charged dust particles to migrate in a directional manner; the second step is that the dust guide groove guides the dust particles to slide in a directional manner, and the needle-shaped protrusions 22 destroy the electrostatic adsorption force between the dust particles and the surface; the third step is that under the action of environmental electrostatics, the surface potential difference pushes the dust particles out of the skin surface.

[0050] The lunar dust protection device for lunar robots provided in this embodiment is prepared by the following method:

[0051] The dust guide groove has a width of 10μm, a depth of 2μm, and a spacing of 20μm. The electrode unit 31 has a length of 10μm, a central body width of 2μm, and two side extension arms widths of 4μm. The needle-like protrusions 22 have the following dimensions: height of 50nm, bottom diameter of approximately 10nm, and top tip diameter of approximately 2nm. The electrode unit 31 and the protrusion array 21 are arranged according to a preset layout. The manufacturing process is as follows:

[0052] S1: A trench array is formed on the surface of the flexible substrate 1 using photolithography.

[0053] S2: The surface of the trench array is treated by plasma etching to enhance the adhesion between the surface and the subsequent coating, and a protrusion array 21 is prepared on the inner wall of the trench array and in the gap plane area.

[0054] S3: A conductive material (using transparent ITO conductive film material) is sprayed onto the surface of the flexible substrate layer 1 between adjacent dust guide channels to form an electrode functional layer 3, which does not cover the dust guide channels to avoid affecting the sliding path of dust particles;

[0055] S4: An anti-adhesion layer 4 is formed by covering the surface of the electrode functional layer 3 and the microstructure dust-guiding layer 2 with an FEP film. The coating thickness is controlled within 500nm, which will not have a significant shielding effect on the electric field. At the same time, flexible encapsulation is completed to obtain a flexible lunar robot dust protection device.

[0056] The implementation method of the electro-induced self-cleaning dust removal control strategy is as follows.

[0057] S1: The optical dust sensor collects area dust particle density data and transmits it to the control module;

[0058] S2: The control module determines whether the dust particle density exceeds the threshold. If it does not exceed the threshold, it maintains low-power intermittent excitation. If it exceeds the threshold, it increases the electric field amplitude and frequency.

[0059] S3: Outputs a driving signal according to a preset logic cycle to drive the electrodes to generate an alternating electric field;

[0060] S4: Continuously monitors dust particle density, and resumes low-power mode after reaching the target. Experimental parameters are set as follows: voltage ±30V, frequency 1~10kHz, duty cycle 50%. The adaptive power consumption adjustment is based on the dust particle density detected by the sensor, which synchronously adjusts the electric field frequency and amplitude. The higher the dust particle density, the closer the electric field frequency is to 10kHz and the amplitude is maintained at ±30V; when the dust particle density is low, the frequency drops to 1kHz and the amplitude drops to ±15V to achieve optimal power consumption.

[0061] A pre-defined mounting process was used to install the lunar dust protection device (flexible skin) onto the surface of the lunar robot. A thermal vacuum experiment was conducted, with a temperature range of −80 to 120°C, to test and compare the adhesion efficiency under different dust particle size distributions. Figure 6 The verification results showed that the dust adhesion rate decreased by 92% and the robot's radiation resistance was enhanced by 15%.

[0062] Example 2

[0063] This embodiment provides a lunar robot, including a body and a lunar dust protection device as described in Embodiment 1, wherein the lunar dust protection device is disposed on the surface of the body to be protected.

[0064] The flexible base layer 1, with its flexibility, can be directly attached to the robot's surface, providing mechanical compliance and radiation resistance to the entire skin structure. It can also adapt to various curved surfaces and flexible joints of the robot. The microstructure dust-guiding layer 2, distributed on the surface of the flexible base layer 1, provides electrostatic shielding and guides the desorption of dust particles, preventing their irregular accumulation. Furthermore, the electrode functional layer 3 applies an alternating electric field, charging the dust particles and causing them to oscillate, disrupting their initial adsorption state and performing electro-oscillatory dust removal. This, combined with the microstructure dust-guiding layer 2, achieves dust prevention and cleaning, improving dust protection reliability. By combining flexible microstructures with an electro-cleaning mechanism, the active separation and automatic removal of lunar dust from complex surfaces can be achieved. This method boasts advantages such as high structural flexibility, low energy consumption, and strong adaptability, and can be widely applied in lunar robots, spacecraft exterior protection, and long-term operation and maintenance of flexible space equipment.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
