It should be noted that the components depicted in the reference drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0052] Referring to Figures 1 to 13 , this application provides an electrostatic discharge system 100, which is applied to a vehicle 10. The vehicle 10 includes a housing 200 and a plurality of electronic devices 110. The electrostatic discharge system 100 includes an electrostatic discharge network 120 and a power distribution device 130. The housing 200 can be made of a composite material. The power distribution device 130 has an input terminal and a plurality of output terminals. The input terminal of the power distribution device 130 is used to connect to a power supply voltage. For example, the power supply voltage can be the voltage output by a power supply device 400 of the vehicle 10. A plurality of the electronic devices 110 are electrically connected to the plurality of output terminals of the power distribution device 130 in one-to-one correspondence; the power distribution device 130 is used to transmit the power supply voltage to the plurality of electronic devices 110. Each of the electronic devices 110 includes a metal housing 111. The electrostatic discharge network 120 is used to connect the metal housings 111 of the plurality of electronic devices 110 and the housing 200; the electrostatic discharge network 120 includes a flexible conductive wire 121, and the flexible conductive wire 121 is arranged in a straight line or bent according to the positions of the plurality of electronic devices 110 and the shape of the housing 200.

[0053] In this embodiment, the vehicle 10 can be an airplane, a vehicle, a ship, etc. The electronic device 110 can be various functional devices inside the vehicle 10. For example, the electronic device 110 can be a controller, a drive motor, a communication device, etc. The material of the housing 200 can be a composite material such as glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, etc.

[0054] The electrostatic discharge network 120 connects the housing 200 and the metal housings 111 of the plurality of electronic devices 110 through the flexible conductive wire 121 to form an equipotential body. When static electricity is generated on a certain part of the housing 200 or the metal housing 111 of a certain electronic device 110, the charge is transmitted and released through the flexible conductive wire 121, thereby eliminating the static electricity. A plurality of the electronic devices 110 can be directly crimped / welded to the flexible conductive wire 121 of the electrostatic discharge network 120 through a jumper wire 600 to improve the stability of the line connection.

[0055] Among them, the flexible conductive wire 121 of the electrostatic discharge network 120 can be lapped according to actual applications. For example, the flexible conductive wire 121 can be crimped on-site to connect to the lap network, or the length can be optimized during the design phase, or a complete electrostatic discharge network 120 can be directly fabricated according to the three-dimensional laying data of the electrostatic discharge network 120 for laying. If there is damage in the flexible conductive wire 121, the damaged part can be cut out, and then the electrostatic discharge network 120 can be reconnected by crimping or welding.

[0056] The metal shell 111 of the electronic device 110 can be made of materials such as copper, tin, aluminum, etc. The metal shell 111 can improve the anti-interference ability of the electronic device 110 and prevent the electronic device 110 from being affected by external signals and thus affecting normal operation.

[0057] The flexible conductive wire 121 has a large bending angle and is less affected by the space or the layout of other components during laying, and can be applied to various layout environments. At positions with a large turning angle, the flexible conductive wire 121 can also be bent to a large extent to adapt to the running direction. For example, when the electrostatic discharge system 100 is applied to a vertical takeoff and landing aircraft, as Figure 2 shown, at the 90° corner of the tail cabin, the flexible conductive wire 121 can be set straight along the position of the electronic equipment, or can be bent along the shape of the fuselage and the position of the electronic device 110, where the electronic device 110 can be a rudder surface controller, a rudder surface actuator, etc. At positions that need to move repeatedly, such as Figure 3 and Figure 4 shown, when the electrostatic discharge system 100 is applied to a vertical takeoff and landing aircraft, during the operation of the vertical takeoff and landing aircraft, the tilting mechanism 800 switches its attitude from 90 degrees to 0 degrees, and the flexible conductive wire 121 can also bend to different angles following the movement of the tilting mechanism 800. Among them, the electronic device 110 can be a pitch controller, an angle sensor, a tilting motor, a propeller motor, etc.

[0058] In one embodiment, when the flexible conductive wire 121 is bent, the radius of curvature of the flexible conductive wire 121 is less than or equal to three times the thickness of the flexible conductive wire 121. In this way, the flexible conductive wire 121 has a large bending angle and can flexibly adapt to various wiring scenarios.

[0059] In one embodiment, the electrostatic discharge system 100 may further include a power distribution device 130. The power distribution device 130 has an input end and a plurality of output ends. The input end of the power distribution device 130 is used to connect to a power supply voltage. For example, the power supply voltage can be the voltage output by the power supply device 400 of the vehicle 10. A plurality of the electronic devices 110 are electrically connected to the plurality of output ends of the power distribution device 130 in a one-to-one correspondence; the power distribution device 130 is used to transmit the power supply voltage to the plurality of electronic devices 110.

[0060] In this application, the housing 200 and the metal housings 111 of multiple electronic devices 110 are connected through an electrostatic discharge network 120 to form an equipotential body for discharging static electricity. The housing 200 and the metal housings 111 of multiple electronic devices 110 are connected through a flexible conductive wire 121, which is less affected by the layout of other components in the space and can be applied to various arrangement environments.

[0061] Refer to Figure 3 、 Figure 4 and Figure 5 In one embodiment, the vehicle 10 further includes a main body 700 and a tilting mechanism 800, and the tilting mechanism 800 can tilt relative to the main body 700. The flexible conductive wire 121 includes a flexible metal wire 121a and a conduit 121b; the conduit 121b is fixed to the tilting mechanism 800, and the flexible metal wire 121a is threaded through the conduit 121b; the flexible metal wire 121a is electrically connected to the main body 700 and the tilting mechanism 800 respectively; the flexible metal wire 121a can move relative to the conduit 121b.

[0062] In this embodiment, the flexible metal wire 121a can be realized by using a metal braided mesh belt. The flexible metal wire 121a has good bending resistance characteristics and high bending strength, and is suitable for laying in a variety of scenarios. The flexible metal wire 121a is arranged inside the conduit 121b, and the bending and telescopic direction of the flexible metal wire 121a is defined by the conduit 121b.

[0063] For example, during the flight of the aircraft, when the tilting mechanism 800 switches its attitude between 0 degrees and 90 degrees, the flexible metal wire 121a is limited in its bending and telescopic direction by the conduit 121b, avoiding interference between the flexible metal wire 121a and other components. At the same time, the conduit 121b also protects the flexible metal wire 121a from being worn.

[0064] The first end of the flexible metal wire 121a can be connected to the housing of the main body 700, and the second end of the flexible metal wire 121a can be connected to the transmission component 810 in the tilting mechanism 800. In this way, the static electricity generated on the electronic device 110 at the tilting mechanism 800 can be conducted to the housing of the main body 700 through the transmission component 810 and the flexible metal wire 121a, thereby realizing static electricity discharge.

[0065] For example, the electronic device 110 at the tilting mechanism 800 includes a power motor and a tilting motor. The power motor is disposed at the movable end of the tilting mechanism 800, and the tilting motor is disposed at the fixed end of the tilting mechanism 800. The power motor and the tilting motor can be connected by a connecting rod. The first end of the flexible metal wire 121a is connected to the housing of the main body 700, and the second end of the flexible metal wire 121a is connected to the connecting rod. In this way, the static electricity generated on the tilting motor and the power motor can be conducted to the housing of the main body 700 through the connecting rod and the flexible metal wire 121a, achieving static electricity release. Among them, the material of the connecting rod can be the same as that of the housing or other conductive materials can be selected to achieve it.

[0066] In one embodiment, the static electricity release system 100 further includes a fixing member 140. The fixing member 140 is disposed on the main body 700 near the tilting mechanism 800; the flexible metal wire 121a passes through the fixing member 140, and the fixing member 140 is used to limit the displacement of the flexible metal wire 121a in the first direction L; there is an included angle between the first direction L and the moving direction of the flexible metal wire 121a. Among them, the fixing member 140 can be implemented by using a tie seat belt.

[0067] In this embodiment, the flexible metal wire 121a passes through the fixing member 140 and the conduit 121b in sequence. The fixing member 140 is disposed on one side of the main body 700 close to the tilting mechanism 800, and the conduit 121b can be fixed at a suitable position on the tilting mechanism 800 according to actual applications to cooperate with the fixing member 140 to limit the running direction of the flexible metal wire 121a, facilitating the extension and contraction of the flexible metal wire 121a when the tilting mechanism 800 tilts.

[0068] For example, the fixing member 140 can be horizontally disposed relative to one side of the main body 700 close to the tilting mechanism 800, so that the flexible metal wire 121a passes through horizontally to limit the displacement of the flexible metal wire 121a in the vertical direction and avoid the random movement of the flexible metal wire 121a from interfering with other devices when the tilting mechanism 800 tilts.

[0069] In one embodiment, the material of the flexible metal wire 121a includes at least one of copper, aluminum, silver, tin, etc.

[0070] In this embodiment, the flexible metal wire 121a can be implemented by using any one of copper, aluminum, silver, tin, etc., or can also be implemented by using an alloy formed by any multiple of copper, aluminum, silver, tin, etc. In this way, a low-impedance channel can be formed to effectively transfer charges, thereby eliminating static electricity.

[0071] In one embodiment, the flexible metal wire 121a can be formed into a braided belt using lightweight aluminum to reduce the overall weight of the electrostatic discharge network 120. Furthermore, the flexible metal wire 121a can reduce the weight of the metal structural parts and fasteners used for the transition by fixed crimping, further reducing the weight of the electrostatic discharge network 120.

[0072] Reference Figure 6 In one embodiment, the vehicle 10 further includes a signal transmission channel 300, and the signal transmission channel 300 is used to transmit communication signals between the plurality of electronic devices 110. The flexible conductive wire 121 is disposed along the signal transmission channel 300.

[0073] In this embodiment, the signal transmission channel 300 can be arranged according to the structure of the vehicle 10, and metal wires are laid along the signal transmission channel 300, so that electrical connection between multiple electronic devices 110 can be achieved, and communication signals can be transmitted between multiple electronic devices 110. The flexible conductive wire 121 also needs to achieve electrical connection between the housing 200 and the metal shells 111 of multiple electronic devices 110. Therefore, the flexible conductive wire 121 can also share the laying path with the signal transmission channel 300, and the wiring harness bundling and fixed position can be consistent with the design of the signal transmission channel 300, so as to achieve electrical connection between the metal shells 111 of multiple electronic devices 110 without the need to design a separate laying channel. In addition, the flexible conductive wire 121 shares the laying path with the signal transmission channel 300, which can also play a role in protecting against electromagnetic interference and improving the transmission quality of communication signals.

[0074] Reference Figure 6 In one embodiment, the signal transmission channel 300 includes a low-voltage signal transmission channel 310 ; the flexible conductive line 121 is arranged along the low-voltage signal transmission channel 310 .

[0075] In the vehicle 10, the low-voltage signal transmission channel 310 has a wide laying range, and most electronic devices 110 need to be connected to the low-voltage signal transmission channel 310. For example, sensors, controllers, communication circuits, etc. distributed in various areas of the vehicle 10 need to transmit low-voltage signals through the low-voltage signal transmission channel 310. The flexible conductive wire 121 can also be laid through the low-voltage signal transmission channel 310 with a wide laying range to achieve electrical connection between multiple electronic devices 110 within the laying range. In addition, the flexible conductive wire 121 can also be laid through the high-voltage signal transmission channel. The low-voltage signal transmission channel 310 referred to in the embodiment of the present application may refer to a signal transmission channel with an operating voltage less than 28V, and the high-voltage signal transmission channel may refer to a signal transmission channel with an operating voltage greater than 28V.

[0076] In one embodiment, the first end of the flexible conductive wire 121 is crimped / welded and fixed to the metal housing 111; the second end of the flexible conductive wire 121 is used for being crimped / welded and fixed to the housing 200; adjacent flexible conductive wires 121 are crimped / welded and fixed to each other.

[0077] In this embodiment, the metal housing 111 and the housing 200 of the electronic device 110 can be fixed to the flexible conductive wire 121 through a jumper wire 600 by pneumatic crimping, as Figure 7 shown. Alternatively, the metal housing 111 and the housing 200 of the electronic device 110 can also be fixed to the flexible conductive wire 121 through a jumper wire 600 by ultrasonic welding, as Figure 8 shown. The jumper wire 600 is directly crimped / welded on the flexible conductive wire 121 of the electrostatic discharge network 120, which can improve the stability of the line connection.

[0078] Referring to Figure 6 , in one embodiment, the electrostatic discharge network 120 further includes a connector 122; the connector 122 is used for connecting adjacent flexible conductive wires 121, the flexible conductive wire 121 to the metal housings 111 of multiple electronic devices 110, and the flexible conductive wire 121 to the housing 200.

[0079] In this embodiment, the connector 122 can be used for the connection between the metal housing 111 of the electronic device and the flexible conductive wire 121, can also be used for the connection between two flexible conductive wires 121, and can also be used for the connection between the flexible conductive wire 121 and the housing 200, which can further improve the reliability of the line connection.

[0080] In one embodiment, the connector 122 can include a communication connector, a radio frequency connector, etc. for electrical signal transmission to realize the charge transmission on the electrostatic discharge network 120.

[0081] Referring to Figure 9 , Figure 10 and Figure 11 , in one embodiment, the vehicle 10 further includes a plurality of structural modules 900, the structural modules 900 have a separation surface, and adjacent structural modules 900 are assembled / dismantled through the separation surface. The electrostatic discharge system 100 further includes an adapter 150; the adapter 150 is arranged on the separation surface of the structural module 900, and the adapter 150 is used for connecting / disconnecting adjacent flexible conductive wires 121.

[0082] In this embodiment, at the separation surface of the electrostatic discharge network 120, adjacent flexible conductive wires 121 or between the flexible conductive wire 121 and the jumper wire 600 can be firmly connected through the adapter 150, as Figure 9As shown, when disassembling and assembling, the docking and separation of the separation surface are achieved by disconnecting the adapter 150, such as Figure 10 shown. In this way, the rapid disassembly and assembly of the separation surface can be realized.

[0083] Referring to Figure 12 , in one embodiment, the vehicle 10 further includes a power supply device 400 and a negative return plate 500. The negative return plate 500 is electrically connected to the negative electrodes of a plurality of electronic devices 110 respectively. Among them, the power supply device 400 can be a storage battery, a power supply device, etc.

[0084] In the circuit, the current starts from the positive electrode of the power supply device 400, passes through the load, and then flows back to the power supply device 400 from the negative electrode of the power supply device 400 to form a loop. The negative return plate 500 can serve as a reference point for the circuit, providing a clear return path for the current, ensuring that the current can flow back to the power supply device 400 smoothly after passing through the electronic device 110, thereby ensuring the normal operation of the circuit. In addition, the negative return plate 500 can also effectively eliminate electromagnetic interference in the circuit, reduce noise in signal transmission, and thus improve the stability and reliability of the circuit.

[0085] Referring to Figure 13 , in another embodiment, the vehicle 10 further includes a power supply device 400, and the electrostatic discharge network 120 is also used to connect the negative electrodes of a plurality of the electronic devices 110 and the negative electrode of the power supply device 400. The electrostatic discharge network 120 is also used to connect the negative electrodes of a plurality of the electronic devices 110 and the negative electrode of the power distribution device 130.

[0086] In this embodiment, the electrostatic discharge network 120 can connect the negative electrodes of a plurality of the electronic devices 110 and the negative electrode of the power supply device 400, playing the role of the negative return plate 500. The current starts from the positive electrode of the power supply device 400, passes through the electronic device 110, and then returns to the positive electrode of the power supply device 400 through the electrostatic discharge network 120. In this way, the weight of the low-voltage cable required for the negative return plate 500 can be saved, and the weight of the vehicle 10 can be further reduced.

[0087] Please refer to again Figure 1, this application also provides a vehicle 10, including a housing 200, a plurality of electronic devices 110, and the above-mentioned electrostatic discharge system 100. Among them, the vehicle 10 can be an aircraft, a vehicle, a ship, etc. The electrostatic discharge system 100 includes an electrostatic discharge network 120. The housing 200 can be made of composite materials. Each of the electronic devices 110 includes a metal housing 111. The electrostatic discharge network 120 is used to connect the metal housings 111 of the plurality of electronic devices 110 and the housing 200; the electrostatic discharge network 120 includes flexible conductive wires 121, and the flexible conductive wires 121 are arranged in a straight line or bent according to the positions of the plurality of electronic devices 110 and the shape of the housing 200.
