[0006] Problems to be solved by the invention

[0007] However, sometimes, particles and gases inside the vehicle become positively charged due to positive charges generated by electrical components. Even if the surface material described in Patent Document 1 is applied, while it can prevent the charging of interior components, it cannot eliminate the positively charged particles and gases floating inside the vehicle. As a result, the driver may experience a slight discomfort with the atmosphere inside the vehicle, or may experience a slight decrease in the vehicle's maneuverability.

[0008] The present invention has been made in view of the above circumstances, and an object thereof is to provide an in-vehicle installation that can reduce the slight discomfort felt by the driver due to positively charged particles or gas floating in the vehicle.

[0009] Technical solutions to problems

[0010] In view of the above-mentioned problems, the present invention relates to an in-vehicle device installed in a vehicle. The in-vehicle device comprises a charged object having a negative surface charge. At least a surface layer of the charged object is composed of a fiber aggregate comprising a plurality of conductive fibers. The conductive fibers are fibers that are negatively charged by exposing the conductive material from a resin material.

[0011] Effects of the Invention

[0012] According to the present invention, the surface of the charged object constituting the object installed in the vehicle is negatively charged. Therefore, even if the particles or gas floating in the vehicle are positively charged, the positive charge of the particles or gas can be removed by the negative charge on the surface of the charged object. In particular, in the present invention, at least the surface layer of the charged object is composed of a fiber aggregate containing a plurality of conductive fibers, and the conductive material of the conductive fibers is negatively charged. Therefore, the negatively charged surface of the charged object is formed three-dimensionally by the fiber aggregate, so that the positive charge of the particles or gas floating in the vehicle can be removed more effectively. In this way, the situation in which the driver feels slightly uncomfortable due to the positive charge of the particles or gas floating in the vehicle can be reduced.

[0020] Below, refer to Figures 1 to 5 , the vehicle interior installation object 1 involved in this embodiment is described.

[0021] The in-vehicle installation object 1 according to this embodiment is installed in the vehicle and includes at least a charged object 10. Figure 1 The charged object 10 shown in FIG. 1 may also be constituted as Figure 4 As shown in (b), it is composed of a charged object 10 and a mounting table 20.

[0022] like Figure 1 As shown, the charged object 10 is a structure in which a base material 11 such as a doll is covered with a fiber aggregate 12A containing a plurality of conductive fibers 12a. As described below, the surface of the charged object 10 is negatively charged by the conductive fibers 12a.

[0023] The substrate 11 is a three-dimensional structure with multiple protruding parts. Examples of such three-dimensional structures include dolls or puppets modeled after animals or characters. In this embodiment, the substrate 11 is a bear doll having a head 11a and a torso 11b. The substrate 11 is formed with a pair of ears 11c, 11c and a nose 11d protruding from the head 11a. Furthermore, the substrate 11 is formed with a pair of arms 11e, 11e and a pair of feet 11f, 11f protruding from the torso 11b.

[0024] like Figure 2 As shown, substrate 11 has a surface 11g made of a woven or non-woven fabric, for example, filled with a cushioning material 11h such as cotton or wool. In this embodiment, charged object 10 has surface layer 12 formed by covering surface 11g with fiber assembly 12A. Thus, at least surface layer 12 of charged object 10 is composed of fiber assembly 12A comprising a plurality of conductive fibers 12a, 12a, ... Alternatively, surface 11g of substrate may be made of a "fabric material composed of conductive fibers."

[0025] Here, the portion of the base material 11 where the head portion 11a and the trunk portion 11b are covered with the fiber assembly 12A becomes the main body 10b of the charged object 10. The charged object 10 is formed with a plurality of protrusions 10t, 10t, ..., protruding from the main body 10b of the charged object 10. The protrusions 10t are the portions where the ear portion 11c, nose portion 11d, wrist portion 11e, and foot portion 11f of the base material 11 are covered with the fiber assembly 12A. Thus, the charged object 10 becomes a three-dimensional structure having the plurality of protrusions 10t, 10t, ....

[0026] In this embodiment, the fiber assembly 12A is composed solely of a plurality of conductive fibers 12a. However, as long as the surface of the charged object 10 is negatively charged, the fiber assembly 12A may also include, for example, natural fibers or synthetic fibers. The plurality of conductive fibers 12a are arranged in a disordered (irregular, random) pattern within the fiber assembly 12A. The conductive fibers 12a expose the conductive material 14 from the resin material 13, thereby negatively charging the conductive material 14.

[0027] Specifically, if Figure 3As shown in FIG. 1 , conductive material 14 extends along the longitudinal direction of conductive fiber 12a. Conductive material 14 is embedded in resin material 13 so as to be exposed from peripheral surface 13b of filament-shaped resin material 13 along the longitudinal direction of conductive fiber 12a. Consequently, conductive material 14 exposed from peripheral surface 13b of conductive fiber 12a is negatively charged.

[0028] In addition, if Figure 3 As shown in (b), the conductive material 14 extends along the longitudinal direction of the conductive fibers 12a. The conductive material 14 is inserted through the linear resin material 13 along the central axis, and the conductive material 14 is exposed from the end surface 13c of the resin material 13. In this case, the conductive material 14 exposed from the end surface 13c of the resin material 13 is also negatively charged.

[0029] By using Figure 3 (a) and Figure 3 Conductive fibers 12a, such as those shown in (b), can utilize the charge of the negatively charged conductive material 14 to remove the positive charge of particles or gases floating in the air A. The diameter of the conductive fibers 12a is preferably 3 to 30 μm, for example. The length of the conductive fibers 12a is preferably 5 to 50 mm, for example.

[0030] As the resin material 13, nylon resin, polyester resin or acrylic resin can be mentioned. As the conductive material 14, carbon or metal can be mentioned. As carbon, for example, polyamide containing conductive carbon black can be mentioned, or carbon fiber can be mentioned. By selecting such a material, the exposed surface of the conductive material 14 can be made negatively charged and the charge can be maintained. In this embodiment, as an example, nylon resin is used for the resin material and carbon is used for the conductive material. As such a negatively charged conductive fiber, for example, Belltron (ベルトロン) (registered trademark) manufactured by KB SEIREN Co., Ltd. can be mentioned.

[0031] In this embodiment, if Figure 4 As shown in (a), the in-vehicle installation 1 may also include a loading platform 20 for loading the charged object 10. The loading platform 20 is made of foam rubber. The rubber material constituting the loading platform 20 is not particularly limited as long as it is an electrically insulating material. Examples of such materials include natural rubber and synthetic rubber. Examples of synthetic rubber include urethane rubber, styrene-butadiene rubber, silicone rubber, and fluororubber.

[0032] The loading platform 20 has a bottom plate 21 for loading the charged object 10, and a side wall 22 rising from the periphery of the bottom plate 21. Although the bottom plate 21 is in the shape of a circular plate, it is not limited to this as long as it can load the charged object 10. By using such a loading platform 20, the lower part of the charged object 10 can be stably accommodated in the storage space 23 surrounded by the bottom plate 21 and the side wall 22. Moreover, an opening portion 24 that opens the storage space 23 is formed on the side wall 22 of the loading platform 20 in a manner that is connected to the storage space 23. The opening portion 24 has a pair of inclined surfaces 24a, 24a formed on the side wall 22. Through the pair of inclined surfaces 24a, 24a, the opening portion 24 opens in a manner that expands toward the upper side.

[0033] The result is that, Figure 4 As shown in (b), the charged object 10 can be stably accommodated by inserting it from the opening 20a above the loading platform 20 and placing it on the loading surface 21a of the bottom plate 21. In addition, even if the lower part of the charged object 10 is accommodated in the storage space 23, the lower part of the charged object 10 can be exposed from the storage space 23 through the opening 24. As a result, the charged object 10 can be efficiently placed in the vehicle 55 (see FIG. 1 ) while maintaining its posture. Figure 5 ) to remove static electricity from particles or gases in air A.

[0034] According to this embodiment, Figure 5 As shown, the interior device 1 is installed on the dashboard 51 in the interior 55 of the vehicle 50. Figure 5 In the state where the charged object 10 is placed on the mounting platform 20, the in-vehicle installation object 1 is arranged at a position where it is difficult to obstruct the view outside the vehicle through the front windshield 52. In addition, as the in-vehicle installation object 1, only the charged object 10 may be arranged on the instrument panel 51.

[0035] Here, while the vehicle 50 is in operation, particles or gases floating in the air A of the vehicle interior 55 may become positively charged due to positive charges generated by electrical components (not shown) of the vehicle 50. Even in such cases, the surface of the charged object 10 constituting the vehicle interior object 1 is negatively charged. Thus, even if the particles or gases floating in the vehicle interior 55 are positively charged, the negative charge on the surface of the charged object 10 can remove the positive charge of the particles or gases.

[0036] At least the surface layer 12 of the charged object 10 is composed of a fiber assembly 12A containing a plurality of conductive fibers 12a. The conductive material 14 of these conductive fibers 12a is negatively charged. Thus, the negatively charged surface of the charged object 10 is three-dimensionally formed by the fiber assembly 12A, effectively removing positive charges from particles and gases floating in the vehicle interior 55. This effect is particularly pronounced because the plurality of conductive fibers 12a are randomly arranged within the fiber assembly 12A.

[0037] In particular, the charged object 10 is a three-dimensional structure having a plurality of protrusions 10t, and thus can three-dimensionally remove the positive charge carried by particles or gases floating in the vehicle interior 55. Furthermore, the mounting platform 20 on which the charged object 10 is mounted is made of a rubber material such as foamed rubber, and the charged object 10 is electrically insulated from the instrument panel 51 by the mounting platform 20. In particular, by foaming the rubber, their insulating properties can be further improved. As a result, for example, even when the surface of the instrument panel 51 is positively charged, the positive charge can be suppressed from moving to the charged object 10, thereby ensuring the effect of removing the charge from the charged object 10. In this way, it is possible to reduce the slight discomfort felt by the driver due to the positive charge of particles or gases floating in the vehicle.

[0038] [Confirmation Test 1]

[0039] As Figure 3 The conductive fiber shown in (b) was prepared by preparing Belltron (registered trademark) manufactured by KBSEIREN Co., Ltd., and a test piece was prepared in which 8% by mass of the conductive fiber was mixed in a felt composed of PET. In the conductive fiber, the resin material is composed of nylon. The size of the test piece is 45 mm × 45 mm. After pre-drying the test piece at 70°C for 1 hour, it was placed under standard conditions for 24 hours. For this test piece, the decay rate after 120 seconds was measured according to the JIS L 1094A method (half-life determination method). As a result, the initial charge voltage of the test piece was -1.61 kV, and the charge voltage after 120 seconds after applying a voltage of 10 kV was -0.11 kV. Based on this result, it can be seen that the test piece is negatively charged by containing the conductive fiber. Moreover, based on the fact that the charge voltage after 120 seconds is lower than the initial charge voltage, it can also be confirmed that the test piece has a charge removal effect by containing the conductive fiber.

[0040] [Confirmation Test 2]

[0041] The test was conducted with the driver under the following conditions 1 to 3. A charged object 10 (see Figure 1 ). Prepare the conductive fibers separately. Figure 3 (a) and Figure 3(b) The charged object 10 of the conductive fiber 12a. In condition 1, Figure 4 (b) shows a state where the charged object 10 is placed on the mounting platform 20 and the in-vehicle installation object 1 is arranged on the instrument panel 51. In condition 2, only Figure 1 The charged object 10 shown is an in-vehicle installation object 1, and is placed on an instrument panel 51. In condition 3, no in-vehicle installation object is placed.

[0042] A plurality of drivers boarded and drove the vehicle under conditions 1 to 3. As a result of the sensory evaluation by the plurality of drivers, the following evaluations A to F were obtained from the drivers under conditions 1 and 2, compared with condition 3.

[0043] Rating A: Little steering play when changing lanes

[0044] Evaluation B: Steering is stable at both low and high speeds

[0045] Rating C: Reduced motion sickness

[0046] Rating D: Reduced fatigue during long-distance driving

[0047] Rating E: Driving becomes smoother

[0048] Rating F: The vehicle accelerates smoothly, including when starting.

[0049] Based on the results, it is considered that under conditions 1 and 2, Figure 3 (a) and Figure 3 The charged object 10 of the conductive fiber 12a of (b) can remove the charge (neutralize) even if the particles or gases floating in the vehicle are positively charged. Therefore, it is believed that the situation in which the driver feels slightly uncomfortable due to the positively charged particles or gases can be reduced. Moreover, it can be seen that these evaluations A to F of condition 1 are higher than those of condition 2. Based on this result, it is believed that the loading platform 20 for loading the charged object 10 is made of foam rubber, thereby electrically insulating the charged object 10 from the instrument panel 51. As a result, it is believed that the negatively charged surface state of the charged object 10 is successfully and stably ensured.

[0050] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made within the scope of the present invention described in the claims.
