Description

[Technical Field]

[0001] The present invention relates to a static electricity neutralizing and eliminating device for eliminating static electricity that is inevitably generated in, for example, an automobile engine. [Background technology]

[0002] For example, in the engine, suspension, drivetrain, and electronic devices of a vehicle, as well as in machine tools and other equipment in which component parts are in a movable state, static electricity is inevitably generated during operation. As is well known, static electricity is a positive or negative charge, and if such positive or negative charge accumulates in a device, it will cause operating resistance and result in a decrease in the performance of the device. For this reason, for example, many static electricity removal devices are available on the market as products for automobile users, and patents have been obtained or patent applications have been filed (see, for example, Patent Document 1), but some of them do not necessarily provide sufficient static electricity removal effects. The reason for this is presumably that each device does not output enough counter power to neutralize and remove the static electricity that is generated. [Prior art documents] [Patent documents]

[0012] The present invention is embodied in the following examples, and also includes various methods that can be improved within the scope of the technical concept. [Example]

[0013] The static electricity neutralization and elimination device 1 of the present invention will be described below. This device is used to neutralize and eliminate static electricity that inevitably occurs in devices having moving parts, such as automobile engines, machine tools, electronic devices, etc. As shown in Fig. 1, this device is configured by laminating a metal multi-plate layer 2 and a magnet / ore layer 3 via a conductivity promoter 5, and further connecting one or more conductive cables 6 to the conductivity promoter 5 in the surface layer portion so that they are led out to the outside. These components are housed in a casing 11 made of, for example, resin or metal.

[0014] The metal multi-plate layer 2, the magnet / ore layer 3, the conductivity promoter 5, and the conductive cable 6 will be described in more detail below. First, as shown in Fig. 1, the metal multi-plate layer 2 is formed by alternately stacking two types of metal element plates 21 and 22 with different ionization tendencies with a conduction promoter 5 interposed therebetween. The first metal element plate 21 constituting the metal multi-plate layer 2 is, for example, a copper plate, and the second metal element plate 22 is an aluminum plate which has a higher ionization tendency than the copper of the first metal element plate 21.

[0015] The first metal element plate 21 is configured to be covered (wrapped) in an individual wrapping body 51 made of conductive metal foil (e.g., copper foil) which serves as the conductivity promoter 5, while the second metal element plate 22, an aluminum plate, is configured so that its outer periphery is covered with aluminum foil as the individual wrapping body 51.

[0016] The copper plates serving as the first metal element plates 21 and the aluminum plates serving as the second metal element plates 22 are laminated while being wrapped in individual wrapping bodies 51. Furthermore, these are laminated alternately, and in this embodiment, as an example, three metal element plates 21 (copper plates) and two metal element plates 22 (aluminum plates) are laminated alternately. Then, in this stacked state, the whole is wrapped in an element wrapping body 52 made of copper foil, for example.

[0017] Next, the magnet / ore layer 3 will be described. As shown in Fig. 1, the magnet / ore layer 3 is configured by providing a cylindrical or prismatic magnet 31 on a conductive metal substrate 30, for example, an aluminum substrate 30. The north pole of this magnet 31 is arranged on the substrate 30 side, and as an example, two magnets 31 are arranged side by side. The magnet 31 preferably has a magnetic flux density of 130 millitesla or more, and as an example, a neodymium magnet or a samarium-cobalt magnet is used.

[0018] These magnets 31 are held by individual wrapping bodies 51 made of, for example, aluminum foil, so as to be wrapped around the outer surface of the substrate 30 . Furthermore, a group of ores 32 is provided on the periphery of the magnet 31 on the substrate 30. Specifically, the substrate 30 and the magnet 31 are tightly wrapped from below by an element wrapping body 52 made of copper foil or the like, which is the conductivity promoter 5, and the entire substrate 30 is covered, and the outer periphery of the magnet 31 is filled with the group of ores 32.

[0019] The ore group 32 is formed by selectively mixing multiple different natural or artificial ores, and may be any material that does not emit radiation, such as natural or artificial ores. For example, various natural ores, including one or more of dolomite, actinite, quartz, feldspars, amphibole, chlorite, kaolin, and mica, or artificial ores such as ceramics and terahertz ores, may be used. Terahertz ores have a high far-infrared radiation effect, which excites the action of surrounding ores, resulting in a synergistic effect of the various ores, thereby improving static elimination performance.

[0020] As an example of the packed state of the magnet / ore layer 3, as shown in FIG. 2(a) and FIG. 1, the magnet / ore layer 3 can be formed so that the upper surfaces of the magnets 31 and the ore mass 32 are at the same height. Of course, other configurations (packing examples) are also possible. For example, in the configuration example shown in Figure 2(b), in order to enhance the magnetic effect, when viewed from the top surface of the magnet / ore layer 3, the magnet 31 protrudes by several millimeters from the layer of ore group 32. Other configurations are also possible. For example, in the configuration example shown in FIG. 2(c), the ore mass 32 is gathered together as a whole in a flat layer, and the magnets 31 are piled up above it.

[0021] The magnets 31 may be provided in two pieces as described above, or in one piece, and any other suitable form may be adopted. The magnet / ore layer 3 is formed as an element in a state where the entire magnet is wrapped (packaged) by copper foil, which is the element wrapping body 52. In this way, the metal multi-plate layer 2 and the magnet / ore layer 3 are individually wrapped in the element wrapper 52 (conductivity promoter 5), and the magnet / ore layer 3 is then stacked on the metal multi-plate layer 2 in this state. After this assembly is completed, the entire assembly is further enveloped by an outer envelope 53. This outer envelope 53 also uses copper foil, and this again encases the entire periphery. It is also possible to laminate a magnet / ore layer 3 on the metal multi-plate layer 2, and then laminate a plate of a metal (copper) different from the substrate 30 on top of this magnet / ore layer 3, and then further encase the entire structure with an outer surface envelope 53.

[0022] A conductive cable 6 is connected to the outer surface covering 53 of the conductivity promoter 5. As shown in Fig. 1 as an example, the conductive cable 6 has a core wire 60 covered with an insulating tube 61, and is provided with a connection terminal 62 at the end thereof, and a ferrite core 63 is provided on the outside of the insulating tube 61 as needed. The metal multi-plate layer 2 and magnet / ore layer 3 integrated as described above are then housed in a casing 11 made of plastic, aluminum, or the like, to complete the static electricity neutralization and removal device 1 of the present invention.

[0023] The static electricity neutralizing and eliminating device 1 of the present invention has the above-described configuration, and when applied to an automobile or the like, it is connected to an appropriate location such as the engine or battery of the vehicle, and all connection points are connected to the earth side (negative side). That is, in the case of a battery terminal, it is connected to the negative pole, in the case of an engine, it is connected to the engine block, and in the case of a vehicle body, it is connected to an appropriate conductive part of the frame.

[0024] Here, the results of a performance test carried out on the static electricity neutralizing and removing device 1 of the present invention are shown. First, the performance test was conducted by comparing the state when the static electricity neutralizing eliminator 1 was installed in a vehicle with the state when it was not installed, and the test items were fuel economy, charge value, quietness, radiation, and output. The vehicles used for the test were mainly light vehicles, and the conditions of each vehicle and the test environment are described below. Furthermore, measurements were taken using the static electricity neutralization and elimination device 1 alone to confirm the radiation manifestation status.

[0025] [1. Fuel economy test] As for fuel economy testing, the inventor is an individual researcher and is unable to conduct rigorous tests at a fixed level using testing equipment. However, since the purpose of the device of the present invention is to improve functionality at a general use level, fuel economy was measured when traveling the same section (92.7 km) at the legal speed on a public road bypass at night, when conditions were nearly identical, for a vehicle equipped with the static electricity neutralizing and eliminating device 1 of the present invention (vehicle equipped with the device) and an identical vehicle without the device (vehicle not equipped with the device). Gasoline consumption was measured using the fill-up method. The static electricity neutralization and elimination devices 1 used were one equipped with one conductive cable 6 (hereinafter referred to as TYPE I) and one equipped with two conductive cables 6 (hereinafter referred to as TYPE II). In the case of Type I, the conductive cable 6 is connected to the negative terminal of the battery. In the case of Type II, one conductive cable 6 is connected to the negative terminal of the battery, and the other conductive cable 6 is connected to the frame in the engine compartment. Regarding the vehicles, vehicle A and a different vehicle B were used.

[0026] <Test Results> The results of the fuel economy test are shown below, and it was confirmed that the installation of the static electricity neutralizing and removing device 1 of the present invention improved fuel economy by approximately 12 to 21%. Vehicle A When not installed: 28.4km / L When equipped with TYPE I: 31.86km / L (+3.46 +12.2%) When equipped with TYPE 11: 34.08km / L (+5.68 +20.0%) Vehicle B When not installed: 24.82km / L When equipped with TYPE I: 30.20km / L (+5.38 +21.68%)

[0027] [2. Charging test] The charging test involved measuring the electrostatic potential at various parts (12 locations) of a vehicle (vehicle B) equipped with the electrostatic neutralization and elimination device 1 (TYPE I) of the present invention (with the conductive cable 6 connected to the negative terminal of the battery) and the same vehicle (vehicle B) without the device installed, using an electrostatic potential meter. In addition, in order to make the vehicle itself electrically charged, the vehicle was driven for about 50 km, and then stopped and measurements were taken at each part with the engine idling. As the electrostatic potential measuring device, for example, Statiron (registered trademark) DZ4 manufactured by Shishido Electrostatic Corporation was used.

[0028] [Table 1]

[0029] The measurement results confirmed that static electricity was effectively neutralized at all measurement points by installing the static electricity neutralizing elimination device 1 of the present invention. It was confirmed that static electricity was effectively neutralized at the engine head, body sides, front bumper, front bumper corners, and rear bumper corners, where the electrostatic potential was particularly high.

[0030] [3. Quietness test] As mentioned above, since the inventor is an individual researcher, the noise reduction test was carried out by simple measurement using a smartphone app (SkyPaw Co. Ltd. Decibel X). Specifically, to create a charged state in the vehicle itself, the vehicle was driven for approximately 50 km, then stopped and the engine was left idling with the hood open. A smartphone was placed on the frame of the engine compartment and the sound pressure level was measured for a specified period of time, and the average value was calculated. The static electricity neutralization and elimination device 1 used was Type II, with one conductive cable 6 connected to the negative terminal of the battery and the other conductive cable 6 connected to the frame in the engine room. Regarding the vehicle, vehicle A was used.

[0031] [Test results] Vehicle A When not wearing: 70.3dB TYPE 11: 67.4 dB (sound pressure level -2.9 dB) The measurement results show that by installing the static electricity neutralizing and eliminating device 1 of the present invention, the sound pressure level is reduced to about -3 dB, and the sound energy is reduced to about half.

[0032] [4. Radiation] Radiation exists in nature at a certain level, and was measured using a Geiger counter (GM tube Geiger counter manufactured by FELLAT) to compare with this situation. First, the radiation dose in the basic indoor environment was 0.13 μSV. On the other hand, the radiation dose on the casing 11 (made of plastic) of the static electricity neutralization and removal device 1 of the present invention was 0.11 μSV. Furthermore, the radiation dose on the casing 11 (made of aluminum) of the static electricity neutralization and removal device 1 of the present invention was 0.14 μSV. The difference in the values ​​of these measurement results was within the range of measurement error, and it was confirmed that no radiation was emitted from the static electricity neutralization and removal device 1 of the present invention.

[0033] [4. Output test] The vehicle's power output was measured using a chassis dynamometer, and the results confirmed an increase in power output of approximately 10% compared to when the device was not installed. The following is a detailed explanation based on the measurement graphs shown in Figures 3-1 and 3-2. The test vehicles and measuring equipment are as follows: Test vehicle: BMW Z3, ​​model CL20, 2000, 139,000 km Measuring equipment: Sakura Dyno System SDS-RS-2 chassis dynamometer

[0034] The graph shown in Figure 3-1 is the output data for a vehicle not equipped with the device, while the graph shown in Figure 3-2 is the output data for a vehicle equipped with the device. In both graphs, from top to bottom, the curve (broken line) indicated by L1 is the corrected torque curve, L2 is the corrected power curve, L3 is the measured power curve, and L4 is the loss power curve. Note that the curves showing data when not fitted have the suffix N, indicating normal, added to the end of each symbol, and are shown as L1(N), L2(N), L3(N), L4(N), etc. Here, the corrected output is the output obtained by adding the loss output, which is the mechanical resistance of the chassis dynamo itself that occurs when the chassis dynamo is driven, to the measured output, and the torque is also processed in the same way and displayed as a corrected torque curve.

[0035] The vehicle without this device, shown in Figure 3-1, recorded a maximum output of 15.8 kgm of corrected torque, 134 PS (98 kW), and 115 PS (84 kW).On the other hand, the vehicle with this device, shown in Figure 3-2, recorded a maximum output of 17.5 kgm of corrected torque, 147 PS (108 kW), and 126.8 PS (92.6 kW). Furthermore, Figure 3-3 is a graph showing the corrected output of both vehicles (vehicle with this device and vehicle without this device), and it can be seen at a glance that the output of the vehicle with this device is higher from the low engine speed range to the maximum speed of over 6000 rpm. The comparison results confirmed that the vehicle with this device had a 110% increase in output compared to the vehicle without this device. [Explanation of symbols]
