Description

Technical Field

[0001] This utility model relates to the field of portable computer equipment technology, and in particular to an automated motion trajectory planning device. Background Technology

[0002] In field military operations, portable computers used for trajectory planning of unmanned aerial vehicles (UAVs) must simultaneously meet the dual requirements of high-level electromagnetic shielding and real-time wireless communication. Traditional rugged computers mostly use fully enclosed conductive metal shells to achieve electromagnetic shielding, but they have the following drawbacks: low communication efficiency, the enclosed structure requires the physical opening of the communication window to activate the antenna, and it is susceptible to corrosion from sand and rain when exposed, and cannot achieve dynamic switching; insufficient environmental adaptability, the fixed shielding structure cannot cope with the complex electromagnetic environment of the battlefield, and the communication window needs to be frequently opened and closed during communication, which makes the mechanical structure vulnerable to damage.

[0003] Chinese Patent Publication No. CN209543206U discloses a ruggedized laptop computer, comprising: a computer body, a retractable handle mounted on the computer body, the retractable handle including a telescopic body and two mounting bodies symmetrically mounted on the computer body, with both ends of the telescopic body connected to the two mounting bodies respectively; the computer body has a pull-tab type external interface protective cover at the external interface, the pull-tab type external interface protective cover has a compact structure, is easy to operate, and fits tightly with the body when fastened, ensuring the overall ruggedized performance and electromagnetic shielding effect; it is equipped with a dual-isolated centrifugal fan for good heat dissipation. This utility model, with its retractable handle and pull-tab type external interface protective cover, helps to reduce the size of the body and enhance the electromagnetic shielding effect.

[0004] Therefore, it can be seen that the above-mentioned ruggedized laptops have the following problems: their electromagnetic shielding structure cannot achieve dynamic switching between communication mode and shielding mode. Utility Model Content

[0005] Therefore, this utility model provides an automated motion trajectory planning device to overcome the problem that the electromagnetic shielding structure in the prior art cannot achieve dynamic switching between communication state and shielding state.

[0006] To achieve the above objectives, the present invention provides an automated motion trajectory planning device, comprising: a portable computer body, which includes a host, a screen, a keyboard, and a protective shell for protecting the portable computer body;

[0007] An electromagnetic shielding layer, disposed inside the protective housing, is used to electromagnetically shield the electromagnetic signals received and transmitted by the host. The electromagnetic shielding layer includes a normal shielding layer and a liquid metal shielding layer. The normal shielding layer has a circular window, within which the liquid metal shielding layer is disposed, forming a complete shielding structure. The liquid metal shielding layer includes microchannels and conductive liquid metal and electrolyte disposed within the microchannels. The conductive liquid metal forms a conductive medium in the electrolyte. By controlling the filling or emptying of the conductive medium within the microchannels, the electromagnetic shielding layer can switch between a shielding state and a communication state.

[0008] An antenna assembly, which is disposed below the liquid metal layer and connected to the host of the portable computer body, is used to transmit and receive communication information.

[0009] An electric field driving mechanism, connected to the liquid metal shielding layer and the portable computer body, includes an independent energy storage module for applying voltage to the conductive liquid metal to switch the shielding state of the liquid metal shielding layer.

[0010] Furthermore, the microchannel includes a serpentine channel network for carrying the conductive medium to form a continuous electromagnetic shielding layer, and spherical liquid storage cavities disposed at the ends of each of the serpentine channel networks for storing the conductive medium collected during communication.

[0011] Furthermore, the serpentine flow channel network is divided into four symmetrically distributed sub-serpentine flow channels, each of which extends radially along the circular window and occupies a 90° fan-shaped area.

[0012] Furthermore, the two ends of the sub-serpentine flow channel are the starting end and the ending end, respectively; the starting end is the end of the sub-serpentine flow channel on the side away from the center of the circular window, and the ending end is the end of the sub-serpentine flow channel on the side close to the center of the circular window.

[0013] Furthermore, the spherical liquid storage cavity is located at the starting end of the sub-serpentine flow channel.

[0014] Furthermore, the height of the sub-serpentine flow channel from the antenna assembly decreases uniformly from the end point to the starting point, thereby increasing the speed at which the conductive medium is drained and recycled back to the spherical reservoir.

[0015] Furthermore, the electric field driving mechanism includes four sets of electrode pairs, each set of electrode pairs being respectively disposed at the spherical liquid storage cavity at the starting point and the ending point of the corresponding sub-serpentine microchannel.

[0016] Furthermore, the electrode pair includes a positive electrode embedded in the inner wall of the end of the sub-serpentine microchannel and a negative electrode embedded in the inner wall of the spherical liquid reservoir, which are used to reduce the surface tension of the conductive liquid metal and form an electric field to create a surface tension gradient in the conductive liquid metal.

[0017] Furthermore, the antenna assembly includes a ring substrate and four sets of fan-shaped antennas disposed on the ring substrate corresponding to the sub-serpentine microchannel, which are used to form four communication modules that can independently switch between shielding and communication states.

[0018] Furthermore, a circular protective cover is provided on the outer side of the protective shell corresponding to the position of the circular window, and an annular sealing gasket is provided on the inner side of the circular protective cover. The outer diameter of the sealing gasket is aligned with the outer edge of the circular window to protect the liquid metal shielding layer.

[0019] Compared with the prior art, the beneficial effect of this utility model is that, through the coordinated control structure of the liquid metal shielding layer and the electrolyte electric field, this utility model can achieve intelligent dynamic switching between shielding state and communication state while maintaining the full sealing protection of the equipment.

[0020] Furthermore, this invention, through the combined design of a normal shielding layer and a liquid metal layer, forms a dynamically adjustable shielding structure in the circular window area, which can maintain the integrity of the overall electromagnetic shielding while quickly opening the local communication window, significantly improving the environmental adaptability of the equipment.

[0021] Furthermore, this invention, through the cooperative structure of the serpentine flow channel network and the end spherical liquid storage cavity, ensures that the conductive liquid metal uniformly covers the flow channel in the shielded state and completely retreats into the liquid storage cavity in the communication state, effectively avoiding signal interference caused by liquid metal residue.

[0022] Furthermore, this invention uses a design of four symmetrically distributed fan-shaped sub-channels to divide the liquid metal migration path into independent control units, which significantly shortens the state switching time and achieves selective shielding in different regions, thereby significantly improving the efficiency of multi-task communication.

[0023] Furthermore, this invention defines the flow channel orientation at the starting and ending points, combines it with a height gradient design, and utilizes gravity and electric field to drive the flow of liquid metal, thereby reducing energy consumption while enhancing system reliability.

[0024] Furthermore, this utility model achieves mechanical protection of the liquid metal shielding layer through a circular protective cover structure. Attached Figure Description

[0033] Please see Figures 1 to 2 As shown, this utility model embodiment provides an automated motion trajectory planning device, comprising:

[0034] A portable computer body, including a host, a screen, a keyboard, and a protective shell for protecting the portable computer body;

[0035] An electromagnetic shielding layer, disposed inside the protective housing, is used to electromagnetically shield the electromagnetic signals received and transmitted by the host. The electromagnetic shielding layer includes a normal shielding layer and a liquid metal shielding layer 1. The normal shielding layer has a circular window, within which the liquid metal shielding layer 1 is disposed, forming a complete shielding structure. The liquid metal shielding layer 1 includes microchannels and conductive liquid metal and electrolyte disposed within the microchannels. The conductive liquid metal forms a conductive medium in the electrolyte. By controlling the filling or emptying of the conductive medium within the microchannels, the electromagnetic shielding layer can switch between a shielding state and a communication state.

[0036] An antenna assembly is disposed below the liquid metal layer 1 and connected to the host of the portable computer body for transmitting and receiving communication information.

[0037] An electric field driving mechanism, connected to the liquid metal shielding layer 1 and the portable computer body, includes an independent energy storage module for applying voltage to the conductive liquid metal to switch the shielding state of the liquid metal shielding layer 1.

[0038] In practice, the normal shielding layer adopts a thick copper-nickel alloy mesh. Those skilled in the art will understand that the normal shielding layer is a preferred embodiment of this utility model. Those skilled in the art can make adaptive replacements based on actual conditions while meeting the electromagnetic shielding effectiveness, which will not be elaborated here.

[0039] In practice, the conductive liquid metal is a GaInSn alloy, and the electrolyte is deionized water with added NaOH.

[0040] Specifically, the microchannel includes a serpentine channel network 11 for carrying the conductive medium to form a continuous electromagnetic shielding layer, and spherical liquid storage cavities 12 disposed at the ends of each of the serpentine channel networks 11 for storing the conductive medium collected in the communication state.

[0041] Specifically, the serpentine flow channel network 11 is divided into four symmetrically distributed sub-serpentine flow channels, each of which extends radially along the circular window and occupies a 90° fan-shaped area.

[0042] It is understandable that dividing the serpentine flow channel network 11 into four symmetrically distributed sub-serpentine flow channels of equal size reduces the path length of the conductive liquid metal from the spherical reservoir 12 to fill the sub-serpentine flow channels or from the sub-serpentine flow channels to return to the spherical reservoir 12, thereby improving the speed at which the liquid metal shielding layer 1 switches between shielding and communication states.

[0043] Specifically, the two ends of the sub-serpentine flow channel are the starting end and the ending end, respectively; the starting end is the end of the sub-serpentine flow channel on the side away from the center of the circular window, and the ending end is the end of the sub-serpentine flow channel on the side closer to the center of the circular window.

[0044] Specifically, the spherical liquid storage cavity 12 is located at the starting end of the sub-serpentine flow channel.

[0045] Specifically, the height of the sub-serpentine flow channel from the antenna assembly decreases uniformly from the end point to the starting point, thereby increasing the speed at which the conductive medium is drained and recycled back to the spherical reservoir.

[0046] In practice, preferably, the slope of the sub-serpentine flow channel is 2%.

[0047] It is understood that when the liquid metal shielding layer is in the shielding state, the electric field drives the liquid metal to flow from the spherical liquid storage cavity 12 to the serpentine flow channel network 11, and the slope slows down the return of the liquid metal; when the liquid metal shielding layer is in the communication state, after the electric field is removed, the liquid metal is drained and recycled back to the spherical liquid storage cavity under the action of gravity and surface tension.

[0048] Specifically, the electric field driving mechanism includes four sets of electrode pairs, each set of electrode pairs being respectively disposed at the spherical liquid storage cavity 12 at the starting point and the ending point of the corresponding sub-serpentine micro-flow channel.

[0049] Specifically, the electrode pair includes a positive electrode embedded in the inner wall of the end of the serpentine microchannel and a negative electrode embedded in the inner wall of the spherical liquid storage cavity 12, which are used to reduce the surface tension of the conductive liquid metal and form an electric field to create a surface tension gradient in the conductive liquid metal.

[0050] In practice, the positive electrode is preferably made of platinum (Pt) to avoid water decomposition interfering with the oxidation reaction; the negative electrode is preferably made of a nickel-based alloy (Hastelloy C-276), which is resistant to strong alkali corrosion; those skilled in the art can adapt the material of the electrode to meet the above requirements and make appropriate substitutions according to the actual situation, which will not be elaborated here.

[0051] Yes, it is understood that an electrolytic cell is formed by the spherical liquid storage cavity 12 (negative electrode) and the endpoint (positive electrode). Liquid metal (GaInSn, gallium indium tin alloy) is connected to the circuit as the anode. A positive voltage is applied in the electrolyte to initiate an oxidation reaction. The generated gallium oxide nanofilm (thickness 5nm-20nm) causes the surface tension of the liquid metal to drop sharply, changing from a state that tends to form droplets to a state that tends to adhere to the inner wall of the flow channel, greatly improving its fluidity. At the same time, the spherical liquid storage cavity 12 (negative electrode) and the endpoint (positive electrode) form a transverse electric field through the electrolyte, causing the liquid metal to form a surface tension gradient. The surface tension is smaller where the charge density is higher, thus causing the liquid metal to move in the direction of lower surface tension.

[0052] Specifically, the antenna assembly includes a ring substrate and four sets of fan-shaped antennas disposed on the ring substrate, corresponding to the sub-serpentine microchannel, to form four communication modules that can independently switch between shielding and communication states.

[0053] Specifically, a circular protective cover 2 is provided on the outer side of the protective shell corresponding to the position of the circular window, and an annular sealing gasket is provided on the inner side of the circular protective cover 2. The outer diameter of the sealing gasket is aligned with the outer edge of the circular window to protect the liquid metal shielding layer 1.

[0054] Working process: The electric field driving mechanism continuously applies voltage to the gallium indium tin alloy in the liquid metal shielding layer through the independent energy storage module, causing it to form an oxide layer to reduce surface tension. Simultaneously, a transverse electric field is generated, creating a surface tension gradient in the gallium indium tin alloy, with low surface tension at the endpoint and high surface tension at the starting point. Under the influence of this surface tension gradient, the gallium indium tin alloy moves directionally from the spherical liquid storage cavity 12 towards the endpoint, filling the entire sub-serpentine microchannel and forming an electromagnetic shielding layer. When communication is required, the host controls the electric field driving mechanism to apply a negative reduction voltage, causing the gallium oxide nanofilm to be decomposed by OH groups in the electrolyte. - The surface tension of the liquid metal is restored and it is emptied and recycled into the spherical liquid storage cavity 12 under the thrust generated by the slope; at the same time, the radio frequency switch switches to the corresponding fan-shaped antenna unit for information transmission and reception; after the communication ends, the electric field drive mechanism resumes the continuous application of voltage to the gallium indium tin alloy in the liquid metal shielding layer 1 to switch the liquid metal shielding layer 1 to the shielding state.

[0055] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
