[0002] This application claims priority to Japanese Patent Application No. 2022-144986, filed on September 13, 2022, the entire contents of which, including the description, claims, drawings and abstract, are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the structure of a vehicle de-energizer for reducing the potential of the vehicle body and control equipment, and the structure of a vehicle equipped with the vehicle de-energizer. Background Technology

[0004] In vehicles, static electricity can be generated in circuits connected to auxiliary components such as drive motors or batteries. Because vehicles are grounded through rubber tires, this static electricity cannot flow to the road surface, causing the circuits or vehicle body to become charged. Furthermore, this static electricity can affect the vehicle's control systems, thus impacting its driving performance.

[0005] Therefore, a method is disclosed in which a thin-film self-discharge eliminator composed of a conductive layer and a discharge layer is installed on the upper surface of a housing that houses the positive electrode circuit of a battery or the like, thereby neutralizing and eliminating the positive charge on the outer surface of the housing, thereby improving the driving performance of the vehicle (for example, see Japanese Patent Application Publication No. 2020-042928).

[0006] In addition, a method is disclosed in which an air ionization self-discharge neutralizer is installed on the negative terminal or outer surface of the battery casing of an auxiliary battery that is grounded on the vehicle body and whose positive terminal supplies power to the auxiliary equipment via a fuse box, thereby reducing the positive charge on the surface of the vehicle body, reducing the repulsive force between the vehicle body and the airflow, and thus improving the aerodynamic performance or handling stability of the vehicle (for example, see Japanese Patent No. 6168157). Summary of the Invention

[0007] However, using the method described in Japanese Patent Application Publication No. 2020-042928, corona discharge is applied to the charge on the outer surface of the housing of the interface terminals, fuses, and relays mounted in the front compartment, thereby changing the external gas flowing in the front compartment into negative ions. If the negative ions are then pulled onto the positive charge on the outer surface to neutralize and remove the static charge, there is a possibility that the hood covering the front compartment may become statically charged. Therefore, there is room for improvement in addressing the static charge on the hood.

[0008] Therefore, the purpose of this disclosure is to reduce the electrical potential of the vehicle body and control equipment, thereby enabling the original vehicle control performance and the original aerodynamic performance to be realized.

[0009] The vehicle-mounted electrostatic eliminator disclosed herein comprises: a self-discharge eliminator mounted on the outer surface of an equipment mounted inside the vehicle body; and a cover plate overlapping and covering the outer surface of the self-discharge eliminator, and covering the side end face of the self-discharge eliminator. The vehicle-mounted electrostatic eliminator is characterized in that the cover plate is made of natural fibers.

[0010] By overlapping a cover plate made of natural fibers onto a self-discharge eliminator, the potential outside the device can be maintained at a level close to zero, reducing electrostatic induction from the device to the vehicle body, thereby lowering the vehicle body's charge potential. This improves the vehicle's inherent controllability and suppresses stripping flow on the vehicle body surface, thus maximizing its aerodynamic performance.

[0011] In the vehicle-mounted eliminator disclosed herein, the cover sheet may be provided with an adhesive layer and thus be adhered to the outside of the self-discharge eliminator and the outer surface of the device via the adhesive layer.

[0012] In this way, by attaching the cover sheet to the equipment and the self-discharge eliminator via a breathable adhesive, the electrostatic potential of the vehicle body and control equipment can be reduced with a simple structure.

[0013] In the vehicle-mounted electrostatic eliminator disclosed herein, a plurality of the cover sheets having the adhesive layer are overlapped and pasted onto the outer surface of the self-discharge eliminator and the outer surface of the device, wherein the total thickness of the plurality of cover sheets is 0.1 to 0.2 mm.

[0014] When the moisture retention and breathability of the cover sheet increase, the electrical potential of the vehicle body and control equipment decreases. When the total thickness of the cover sheets that overlap to some extent increases, the overall moisture retention of the cover sheets increases, thereby reducing the electrical potential of the vehicle body. Conversely, if the total thickness becomes too large, the overall breathability of the cover sheets decreases, and the electrical potential of the vehicle body and control equipment no longer decreases. Moreover, the reduction in the electrical potential of the vehicle body is greatest when the total thickness is between 0.1 and 0.2 mm. Therefore, by setting the total thickness to between 0.1 and 0.2 mm, the electrical potential of the vehicle body and control equipment can be effectively reduced.

[0015] In the vehicle-mounted eliminator disclosed herein, the following method may also be adopted: for the cover plate, the periphery of the cover plate is fixed to the outer surface of the device at the outside of the self-discharge eliminator, thereby clamping the self-discharge eliminator between the cover plate and the device.

[0016] Therefore, a vehicle-mounted eliminator can be constructed using a simple structure in which only the periphery of the cover plate is fixed to the equipment, without fixing the cover plate to the self-discharge eliminator.

[0017] In the vehicle-mounted static electricity removal device disclosed herein, the cover sheet may also be made of Japanese washi paper or cotton nonwoven fabric.

[0018] Because the cover sheet is made of common materials such as Japanese washi paper or kapok, the cost can be reduced.

[0019] The vehicle disclosed herein includes: a device mounted inside the vehicle body; a vehicle-mounted electrostatic eliminator comprising a self-discharge eliminator and a cover plate, wherein the self-discharge eliminator is mounted on the outer surface of the device, the cover plate is overlapped on the outside of the self-discharge eliminator and covers the outside, and covers the side end face of the self-discharge eliminator, the vehicle being characterized in that the device is configured in a manner close to a structural component of the vehicle body, and the cover plate is made of natural fibers.

[0020] By overlapping a cover plate made of natural fibers with a self-discharge static eliminator, the potential of the device can be maintained at a level close to zero, reducing electrostatic induction to structural components of the vehicle body near the device, thereby lowering the vehicle body's electrical potential. This allows the vehicle's inherent controllability to be realized and suppresses the generation of stripping flows on the vehicle body surface, thus enhancing its inherent aerodynamic performance.

[0021] In the vehicle disclosed herein, the device may also be configured such that it includes at least one of a fuse box, a battery, and an inverter housed inside the front compartment of the vehicle body, with its upper surface covered by a hood. The fuse box, the battery, and the inverter are configured in proximity to the hood, and the vehicle-mounted power-removing device is installed on at least one of the cover of the fuse box, the cover or side of the battery housing that houses the battery, and the cover of the inverter housing that houses the inverter.

[0022] This allows the potential outside the fuse box, battery, and inverter to be maintained at a level close to zero, thereby reducing electrostatic induction to the hood, which is located close to the fuse box, battery, and inverter, and further reducing the hood's electrical potential. This enables the vehicle to maintain its inherent control performance and suppresses the generation of stripping flows on the hood surface, thus maximizing its aerodynamic performance.

[0023] In the vehicles disclosed herein, the cover sheet may also be made of Japanese washi paper or cotton nonwoven fabric.

[0024] Because the cover sheet is made of common materials such as Japanese washi paper or kapok, the cost can be reduced.

[0025] This disclosure can reduce the electrical potential of the vehicle body and control equipment, thereby enabling the vehicle to perform its original control performance and its original aerodynamic performance. Attached Figure Description

[0035] Hereinafter, the vehicle 100 of the embodiments and the vehicle de-energizing devices 32, 33, and 34 of the embodiments will be described with reference to the accompanying drawings. The arrows FR, UP, and RH shown in the accompanying drawings represent the front, upper, and right sides of the vehicle 100, respectively. Furthermore, the opposite directions of each arrow FR, UP, and RH represent the rear, lower, and left sides, respectively. In the following description, only the directions of front-back, left-right, and up-down will be used, unless otherwise specified, to represent the front-back direction of the vehicle 100, the left-right direction, and the up-down direction.

[0036] like Figure 1 As shown, a front compartment 11 is provided at the front of the vehicle 100. The front compartment 11 is the interior space of the body 10, whose upper surface is covered by a hood 13, a structural component of the vehicle 100, located further forward than the front bulkhead 14. Inside the front compartment 11 are a drive unit 21 consisting of an electric motor or engine, an inverter 22 that converts DC power from a high-voltage battery (not shown) into AC power and supplies it to the electric motor of the drive unit 21, an auxiliary battery 23, and a fuse box 24. Figure 2 As shown, the rear end of the hood 13 is rotatably fixed to the body 10, and the front end opens vertically as indicated by arrow 91 to open and close the front compartment 11. The hood 13 consists of an outer panel 13A and an inner panel 13B (see reference). Figure 4 The upper surfaces of the inverter 22, battery 23, and fuse box 24 are mounted in the front compartment 11 such that they are close to the hood 13 when the hood 13 is closed. In addition, the front compartment 11 also houses devices such as radiators, but these are not shown in the illustrations.

[0037] return Figure 1 Vehicle-grade static eliminators 32 and 34 are respectively installed on the upper surface of the cover of the metal inverter housing 22A that houses the inverter 22, and on the upper surface of the cover 26 of the resin fuse box 24. Furthermore, as... Figure 1 , 2As shown, a vehicle de-energizer 33 is installed on the resin battery casing 23A that houses the auxiliary battery 23. The vehicle de-energizer 33 consists of a vehicle de-energizer 33A installed on the upper surface of the cover of the battery casing 23A, vehicle de-energizers 33B and 33C installed in an L-shape on the cover and left side of the battery casing 23A, and a vehicle de-energizer 33D installed on the front side of the battery casing 23A.

[0038] Next, in reference Figure 3 , 4 At the same time, details of the fuse box 24 and the vehicle-mounted electrical discharge device 34 installed on the upper surface of the cover 26 of the fuse box 24 will be described.

[0039] like Figure 3 As shown, the fuse box 24 consists of a resin body 25 and a resin cover 26 mounted on the upper surface of the body 25. Multiple fuses 27 are housed inside the body 25. A vehicle-grade electrical eliminator 34 is mounted on the upper outer surface 26A of the cover 26.

[0040] like Figure 4 As shown, the vehicle-mounted electrostatic eliminator 34 consists of a thin sheet-like self-discharge eliminator 35 and a cover plate 36 that covers the outer surface 35C and side end face 35D of the self-discharge eliminator 35.

[0041] The self-discharge eliminator 35 comprises a conductive aluminum adhesive tape 35A and a metal coating 35B coated on the aluminum adhesive tape 35A. The metal coating 35B is a thin film coated with a metal paint containing fine metallic material. The metallic material contained in the metal coating 35B is shaped by bending a circular plate with a U-shaped cross-section, and is believed to generate corona discharge from its edges. Therefore, the metal coating 35B constitutes a discharge layer that generates corona discharge, and the self-discharge eliminator 35 is an air ionization self-discharge neutralization eliminator.

[0042] The cover sheet 36 is composed of Japanese washi paper 36A and an adhesive layer 36B. Japanese washi paper 36A is made of natural fibers with moisture-retaining and breathable properties. The adhesive layer 36B adheres the Japanese washi paper 36A to the outer surface 35C, side end face 35D, and outer surface 26A of the self-discharge eliminator 35. The adhesive layer 36B is breathable. The outer surface 36C of the cover sheet 36 is in contact with external gases flowing into the forward compartment 11.

[0043] Next, the function and effect of the vehicle de-energizing device 34 configured as described above will be explained. For example... Figure 4As shown, the upper end of the fuse 27 housed in the fuse box 24 carries a positive static charge. Through electrostatic induction of this positive static charge, a negative static charge is generated on the lower surface of the cover 26 of the fuse box 24, and due to this electrostatic induction, a positive static charge is generated on the upper outer surface 26A of the cover 26.

[0044] The positive static electricity carried on the outer surface 26A of the upper side of the cover 26 is transferred to the metal coating 35B through the aluminum adhesive tape 35A. Corona discharge then occurs from the upper surface of the metal coating 35B (the edge protrusion of the outer surface 35C of the self-discharge eliminator 35) and the edge protrusion of the side end face 35D of the aluminum adhesive tape 35A. Because the adhesive layer 36B and the Japanese washi paper 36A are breathable, thus... Figure 4 As indicated by arrow 92, based on the charge of the positive electrostatic charge, the external gas flowing from the front grille 12 into the front compartment 11 transforms into negative ions, which are then attracted to the periphery of the positive electrostatic potential corona discharge protrusions, namely the outer surface 35C of the aluminum adhesive tape 35A and the edge protrusions of the side end face 35D. The attracted negative ions then neutralize and de-charge the positive electrostatic potential of the cover 26, which has passed through the breathable cover plate 36, thereby reducing the potential of the cover 26 to near zero.

[0045] While the reason why the potential of the cover 13 is maintained at a potential equivalent to zero is not explicitly stated here, it can be considered as follows: The vehicle static eliminator 34 of the embodiment reduces the surface potential of the cover 26 to zero potential by means of a self-discharge eliminator 35. Since the Japanese washi paper 36A of the cover sheet 36 has a suitable thickness that provides both breathability and moisture retention, the moisture contained in the external air is stably retained. Through the conductive effect of the moisture contained in the Japanese washi paper 36A, the surface potential of the cover 26 is maintained at zero potential. Here, since the cover sheet 36 has a suitable thickness that provides light-blocking properties that prevent corona discharge protrusions from being visible, electrostatic induction to the cover 13 is prevented, and thus it can be considered that the potential of the cover 13 is maintained at a potential equivalent to zero. This will be discussed later. Figure 9 Let me explain in detail.

[0046] Here, refer to Figure 5 , 6 The changes in the electrical potential of the cover 26 and the body 10 relative to the breathability and moisture retention of the cover sheet 36 will be explained. According to the inventor's research, such as... Figure 5 As shown, it was confirmed that as the breathability of the cover plate 36 increases, the electrical potential of the body 10 and the cover 26 decreases. Furthermore, as... Figure 6 As shown, it was confirmed that as the moisture retention of the cover plate 36 increases, the electrical potential of the body 10 and the hood 13 decreases.

[0047] Therefore, it is understood that the breathability and moisture retention of the cover sheet 36 are necessary for achieving the above-mentioned functions and effects.

[0048] Furthermore, according to the inventor's research, such as Figure 7 As shown, it was confirmed that when multiple cover plates 36 are overlapped to increase the total thickness of the cover plates 36, the potential of the cover 26 decreases; however, when the number of overlapped plates is further increased to further increase the total thickness of the cover plates 36, the potential of the vehicle body 10 increases. Furthermore, it was confirmed that when the total thickness of the overlapping cover plates 36 is 0.1 to 0.2 mm, the potentials of the vehicle body 10 and the cover 26 are at their lowest.

[0049] This situation can be considered as follows: when the number of overlapping sheets of the cover plate 36 is increased, the moisture retention of the cover plate 36 increases, thus becoming the thickness of the invisible corona discharge protrusion. As a result, the potential of the body 10 and the hood 13 decreases. However, when the number of overlapping sheets is too large, the air permeability of the cover plate 36 will decrease, and thus the potential of the cover 26 will rise.

[0050] Next, in reference Figure 9 At the same time, by comparing with the case where the self-discharge eliminator 35 as described in Patent Document 1 is installed on the outer surface 26A of the cover 26 of the fuse box 24 without the cover plate 36, the function and effect of the vehicle eliminator 34 of the embodiment are explained.

[0051] like Figure 9 As shown, when the self-discharge eliminator 35 is installed on the cover 26 of the fuse box 24 without a cover plate 36, a rise in the electrical potential of the vehicle body 10 occurs. While the cause is not explicitly stated, it can be assumed to be as follows.

[0052] When the self-discharge eliminator 35 is installed on the cover 26 of the fuse box 24 without a cover plate 36, it is similar to the previously referenced Figure 4 Similarly, as previously described, due to the positive static electricity carried on the outer surface 26A of the upper side of the cover 26, corona discharge is generated from the upper surface of the metal coating 35B (the edge protrusion of the outer surface 35C of the self-discharge eliminator 35) and the edge protrusion of the side end face 35D of the aluminum adhesive tape 35A. Without the cover plate 36, as... Figure 9As shown, since corona discharge protrusions are visible from the hood 13 side when corona discharge occurs, electrostatic induction 93 is generated on the inner panel 13B of the hood 13 corresponding to the corona discharge potential of the positive static charge. Therefore, the inner panel 13B of the hood 13 becomes negatively potentialed. Furthermore, it can be considered that positive static electricity is generated on the outer panel 13A through electrostatic induction of the air or insulation material between the inner panel 13B and the outer panel 13A. Therefore, it can be considered that the potential of the vehicle body 10 has increased.

[0053] On the other hand, as previously explained, in the vehicle static electricity removal device 34 of the embodiment, the surface potential of the cover 26 is reduced to zero potential by utilizing the self-discharge type static electricity remover 35, and the surface potential of the cover 26 is maintained at zero potential by utilizing the conductive effect of the moisture contained in the Japanese washi paper 36A of the cover sheet 36. Furthermore, by having an appropriate thickness that provides light-shielding properties that prevent corona discharge protrusions from being visible, electrostatic induction to the hood 13 is prevented. As a result, it can be considered that the situation where the hood 13 becomes charged due to electrostatic induction is suppressed, and the effect of reducing the potential of the vehicle body 10 is achieved.

[0054] Next, in reference Figure 8 Meanwhile, other embodiments of the vehicle de-energizing device 34A will be described. (This is in contrast to the previously referenced...) Figure 4 For the same parts as the previously described vehicle-mounted electrostatic discharge device 34, the same symbols will be used and the descriptions will be omitted.

[0055] like Figure 8 As shown, the vehicle-mounted electric shock eliminator 34A does not have an adhesive layer 36B, and the cover plate 36 is made solely of Japanese washi paper 36A. Furthermore, the periphery of the Japanese washi paper 36A is fixed to the outer surface 26A of the fuse box 24 by an adhesive 37, and the self-discharge eliminator 35 is sandwiched between the lower surface of the Japanese washi paper 36A and the upper outer surface 26A of the fuse box 24. Here, the outer surface 35C of the self-discharge eliminator 35 and the Japanese washi paper 36A can be in contact, and a small gap 38 can also be left between the outer surface 35C of the self-discharge eliminator 35 and the Japanese washi paper 36A.

[0056] A thin air layer is formed between the lower surface of the Japanese washi paper 36A of the vehicle static eliminator 34A and the upper outer surface 26A of the fuse box 24, thus creating a breathable structure similar to the adhesive layer 36B. The vehicle static eliminator 34A performs the same function and effect as the previously described vehicle static eliminator 34.

[0057] Although the structure of the vehicle-mounted static eliminator 34A, which is mounted on the cover 26 of the fuse box 24, has been described above, the vehicle-mounted static eliminator 32, which is mounted on the outer surface of the inverter housing 22A, and the vehicle-mounted static eliminator 33, which is mounted on the outer surface of the battery housing 23A, have the same structure as the vehicle-mounted static eliminator 34, so the description is omitted.

[0058] Because the vehicle 100 of the embodiment has vehicle-specific static electricity removal devices 32, 33, and 34 installed on the cover of the inverter housing 22A (containing the inverter 22), the cover or side of the battery housing 23A (containing the battery 23), and the cover 26 of the fuse box 24, respectively, which are positively charged with static electricity, electrostatic induction towards the adjacent hood 13 can be reduced. This suppresses the charging of the hood 13, lowers the potential of the vehicle body 10, and prevents the potential of the vehicle body 10 from affecting the control system or sensors, thereby allowing the original control performance of the vehicle 100 to be realized. Furthermore, because positive static electricity can be suppressed on the outside of the vehicle body 10, the generation of stripping flow on the surface of the hood 13 can be suppressed, thereby allowing the original aerodynamic performance to be realized.

[0059] Although the above description mentions that the cover sheet 36 is made of Japanese washi paper 36A, it is not limited to this. It can be made of natural fibers that have moisture-retaining and breathable properties, such as kapok nonwoven fabric.

[0060] Furthermore, although the above description describes the self-discharge eliminator 35 as being composed of a conductive aluminum adhesive tape 35A and a metal coating film 35B, it is not limited to this. For example, instead of aluminum flake particles, it can be constructed as a carbon coating film formed by directly applying a carbon coating containing carbon particles to the outer surface of the cover 26. Alternatively, instead of coating the surface, the surface of the aluminum adhesive tape 35A can be knurled or finely wired to form extremely fine protrusions.

[0061] Furthermore, although the description has described the installation of vehicle-use de-energizers 32, 33, and 34 on the cover of the inverter housing 22A, the cover or side of the battery housing 23A, and the cover 26 of the fuse box 24, respectively, located inside the front compartment 11, it is not limited to this. For example, the vehicle-use de-energizer 34 may also be installed on the upper surface of the drive unit 21, located inside the front compartment 11, or on the upper surface or side of other equipment such as an airflow sensor. Additionally, the vehicle-use de-energizer 34 may also be installed on other equipment, such as the auxiliary battery housing, located in the rear compartment of the vehicle 100. In this case, the potential of the rear hood covering the rear compartment, which is located close to the equipment, can be reduced. Here, the rear hood is a structural component of the vehicle body 10.
