ELECTRIC VEHICLE COMPONENT, METHOD FOR PRODUCING ELECTRIC EQUIPMENT FOR VEHICLE, AND CONDUCTIVE CIRCUIT Cross-reference to related applications

This application is based on Japanese Patent Application No. 2016-122836 filed on June 21, 2016, the contents of which are incorporated herein by reference.

The present disclosure relates to a vehicle electrical component mounted on a vehicle, a method for manufacturing the vehicle electrical component, and a conductive path forming apparatus.

Conventionally, various electrical components are mounted on vehicle electrical components. For example, in an air conditioning unit of a vehicle air conditioner, various electrical components such as an electric actuator that drives a door disposed in the housing, an electric motor that drives a fan, and a sensor are mounted. And the electrical component mounted in the electric component for vehicles is electrically connected with respect to a control apparatus, a power supply device, etc. via a wire harness as shown, for example in patent document 1. FIG.

JP 2004-175266 A

Currently, it is difficult for robots to automate wiring components such as the housing of wire harnesses, and humans often do it. When manipulating the wiring harness, it is necessary to pay attention to the fact that the wiring harness will not be damaged and the tension of the wiring harness will not be excessive when assembled to the electrical component. This is a factor causing a decrease in efficiency.

Therefore, the present inventors have formed an existing wire harness by forming a conductive path with respect to an electrical component (for example, a casing) of an electrical component for a vehicle by a method such as printing, plating, or pressing of a conductive material. We are considering reducing it.

However, as a result of studies by the present inventors, when a conductive path is formed on an electrical component of a vehicle electrical component by a method such as printing, plating, or pressing of a conductive material, the cross-sectional area of the conductive path is small. It turns out that the electrical resistance increases. In this case, when a large current flows through the conductive path, the conductive path may generate heat, and the electrical member may be melted.

In order to suppress the melting damage of the electrical member, for example, it is necessary to secure the cross-sectional area of the conductive path and reduce the electrical resistance of the conductive path. As a method for securing the cross-sectional area of the conductive path, it is conceivable to increase the width of the conductive path.

However, when ensuring the cross-sectional area of the conductive path by increasing the width of the conductive path, it is necessary to secure a sufficient area for forming the conductive path on the surface of the electrical component, which is realized on an actual product. Have difficulty.

The present disclosure relates to an electrical component for a vehicle, a method for manufacturing the electrical component for a vehicle, and formation of an electrical pathway that can prevent the electrical component from being melted by heat generated by the electrical pathway formed on the electrical component to which the electrical component is attached. An object is to provide an apparatus.

According to one aspect of the present disclosure, an electrical component for a vehicle on which an electrical component is mounted is an electrical component to which the electrical component is attached, and at least one that is formed on the electrical component and is electrically connected to the electrical component. A conductive path of a book. And the conductive path is comprised including the laminated body on which the electroconductive material was laminated | stacked.

As described above, when the conductive path is formed on the electrical member, complicated work can be reduced as compared with the configuration in which the wire harness is arranged on the electrical member. As a result, the production efficiency of vehicle electrical components can be improved.

Furthermore, if the conductive path is made of a laminate of conductive materials as in the present disclosure, the thickness of the conductive path can be increased and the electrical resistance of the conductive path can be suppressed. Thus, the melting damage of the electrical member can be suppressed.

Therefore, it is possible to realize an electrical component for a vehicle that can suppress the electrical component member from being melted by heat generated by the conductive path formed in the electrical component member.

Further, in the vehicle electrical component, the conductive path is composed of a cured body obtained by curing a conductive material laminated on the surface of the electrical component member, and unevenness is formed on a part of the surface. Thus, if a conductive path is comprised with the hardening body of the electroconductive material laminated | stacked on the surface of the electrical equipment member, the thickness of a conductive path can be enlarged and the electrical resistance of a conductive path can be suppressed. Furthermore, if the conductive path is configured such that irregularities are formed on a part of the surface, the surface area of the conductive path can be increased and the heat dissipation of the conductive path during energization can be improved.

Therefore, it is possible to realize an electrical component for a vehicle that can sufficiently suppress melting of the electrical component due to heat generated in the conductive path formed in the electrical component.

According to another aspect of the present disclosure, in a method for manufacturing an electrical component for a vehicle including an electrical component having at least one conductive path electrically connected to the electrical component formed on a surface, first, the electrical component A conductive material having fluidity is supplied to the surface of the substrate.

In the manufacturing method described above, a conductive material laminate is formed by supplying a new conductive material to the surface of the conductive material supplied to the surface of the electrical member at least once. Furthermore, in the above-described manufacturing method, the laminated body is cured by at least one of drying, baking, and chemical reaction, thereby forming a conductive path having irregularities on a part of the surface.

Thus, by forming a laminate of a conductive material on the surface of the electrical member and curing the laminate, a conductive path having a large thickness and a low electrical resistance can be formed on the surface of the electrical member. And when laminating | stacking a conductive material, since an unevenness | corrugation is formed in a part of surface of a conductive path, the surface area of a conductive path can be increased and the heat dissipation of the conductive path at the time of electricity supply can be improved.

Therefore, according to the manufacturing method of the present disclosure, it is possible to manufacture a vehicular electrical component that can prevent the electrical component from being melted by heat generated by the conductive path formed in the electrical component.

According to another aspect of the present disclosure, a conductive path forming device that forms at least one conductive path electrically connected to an electrical component on a surface of an electrical component includes a material supply device, a material curing device, .

The material supply device has a plurality of material supply units for supplying a conductive material to the surface of the electrical component. Moreover, the material curing device has an energy output unit that outputs energy for curing the conductive material.

Among the plurality of material supply units, some of the material supply units are configured to supply a conductive material to the surface of the electrical component. Further, among the plurality of material supply units, the other material supply units excluding a part of the material supply units are configured to supply the conductive material to the surface of the conductive material already supplied to the surface of the electrical component member. ing. The conductive path is composed of a laminate of conductive materials supplied from a plurality of material supply units, and unevenness is formed on a part of the surface.

As described above, the conductive material is formed on the surface of the electrical component by the material supply device, and the conductive material is cured by the material curing device, so that the conductive path having a large thickness and a low electrical resistance is obtained. Can be formed on the surface. And when laminating | stacking a conductive material, since an unevenness | corrugation is formed in a part of surface of a conductive path, the surface area of a conductive path can be increased and the heat dissipation of the conductive path at the time of electricity supply can be improved.

Therefore, according to the conductive path forming device of the present disclosure, it is possible to suppress the electrical component member from being melted by heat generated by the conductive path formed in the electrical component of the vehicle electrical component.

In particular, the conductive path forming apparatus of the present disclosure is configured to supply the conductive material from the other material supply unit to the surface of the conductive material supplied from the partial material supply unit to the surface of the electrical component. Yes. According to this, since it is not necessary to reciprocate the same material supply section many times when forming a laminate of conductive materials, a laminate of conductive materials can be formed on the surface of the electrical component in a short time. Is possible.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, the same or equivalent parts as those described in the preceding embodiments are denoted by the same reference numerals, and the description thereof may be omitted. Further, in the embodiment, when only a part of the constituent elements are described, the constituent elements described in the preceding embodiment can be applied to the other parts of the constituent elements. The following embodiments can be partially combined with each other even if they are not particularly specified as long as they do not cause any trouble in the combination.

(First embodiment)
This embodiment will be described with reference to FIGS. In the present embodiment, an example in which the vehicle electrical component of the present disclosure is applied to a vehicle air conditioner will be described. A vehicle air conditioner is an apparatus that air-conditions a vehicle interior.

The vehicle air conditioner includes an air conditioning unit 1 that adjusts the temperature of air blown into the passenger compartment. The air conditioning unit 1 is disposed, for example, inside the foremost instrument panel in the passenger compartment.

As shown in FIG. 1, the air conditioning unit 1 includes an air conditioning case 10 constituting an outer shell. The air conditioning case 10 is formed with an air passage for air toward the vehicle interior. In the present embodiment, the air conditioning unit 1 constitutes an electrical component for a vehicle, and the air conditioning case 10 constitutes an electrical component to which an electrical component is attached.

The air conditioning case 10 is molded of an insulating resin (for example, polypropylene) having a certain degree of elasticity and excellent strength. The air conditioning case 10 is actually configured by fastening a plurality of divided case bodies with fastening elements such as screws and clips for convenience in resin molding, assembly of built-in components, and the like.

The air conditioning case 10 houses a blower 11 that blows air into the passenger compartment. The blower 11 is an electric blower that drives a centrifugal fan (for example, a sirocco fan or a turbo fan) 111 with an electric motor 112. The electric motor 112 is attached to the air conditioning case 10.

On the air flow upstream side of the blower 11 in the air-conditioning case 10, an inside air introduction port 121 for introducing air inside the vehicle interior (that is, inside air) to the air suction side of the air blower 11, and air outside the vehicle compartment (ie, outside air). ) Is formed.

Inside the air conditioning case 10, although not shown, an inside / outside air door that adjusts the ratio of the opening area of the inside air introduction port 121 and the opening area of the outside air introduction port 122 is arranged. The inside / outside air door is driven by an electric actuator 13 attached to the outside of the air conditioning case 10.

An evaporator 14 for cooling the air blown from the blower 11 is disposed on the air blowing side of the blower 11 in the air conditioning case 10. The evaporator 14 is a cooling heat exchanger that cools the air flowing inside the air conditioning case 10 by an endothermic effect when the refrigerant is vaporized. The evaporator 14 constitutes a vapor compression refrigeration cycle together with a compressor, a radiator, an expansion valve, and the like (not shown).

A heater core 15 that heats the air that has passed through the evaporator 14 is disposed on the downstream side of the air flow of the evaporator 14 in the air conditioning case 10. The heater core 15 is a heat exchanger for heating that heats the air that has passed through the evaporator 14 by heat exchange with engine coolant (not shown).

Here, although not shown, the air conditioning case 10 is formed with a bypass passage that bypasses the heater core 15 and flows air. Further, an air mix door that adjusts the air volume ratio between the air volume passing through the heater core 15 and the air volume passing through the bypass passage is disposed inside the air conditioning case 10. The air mix door is driven by an electric actuator 16 attached to the outside of the air conditioning case 10.

Although not shown, the air conditioning case 10 is provided with a plurality of outlet openings for blowing air after passing through the heater core 15 or the bypass passage to the vehicle interior side, on the most downstream side of the air flow. The air blown out from the blowout opening is supplied into the vehicle compartment from a blowout portion provided in the vehicle compartment via a duct (not shown).

Here, the air conditioning unit 1 of the present embodiment includes a control device and a power source (not shown) on the surface of the air conditioning case 10 that is an electrical component, such as the electric motor 112 of the blower 11 and the electric actuators 13 and 16 for driving the door. A conductive path 100 connected to the device is formed.

This conductive path 100 replaces the wire harness that has been used in the air conditioning unit 1 until now. Specifically, as shown in FIG. 2, a plurality of conductive paths 100 are formed on the surface of the air conditioning case 10 of the present embodiment.

The conductive path 100 includes a laminated body in which conductive materials are laminated. Specifically, the conductive path 100 is configured by a cured body obtained by curing a conductive material that is stacked several times on the surface of the air conditioning case 10. The surface of the conductive path 100 is covered with a protective film 110 having an insulating property. Thus, if it is set as the structure which covers the surface of the conductive path 100 with the protective film 110, the corrosion of the conductive path 100, a disconnection, a short circuit, etc. can be suppressed.

Here, FIG. 3 shows a cross-sectional shape of a conductive path CE which is a comparative example of the conductive path 100 of the present embodiment. The conductive path CE shown in FIG. 3 is a cured body obtained by curing the conductive material supplied to the surface of the air conditioning case 10 at one time.

If many conductive materials are supplied to the surface of the air conditioning case 10 at once, the conductive material spreads in the surface direction of the air conditioning case 10 due to surface tension in the process of forming the conductive path CE. That is, if it is attempted to sufficiently secure the thickness Lt1 in the conductive path CE, the width Lw1 of the conductive path CE is increased as shown in FIG. For this reason, when the conductive path CE of the comparative example is formed for the air conditioning case 10, it is necessary to secure a sufficient area for forming the conductive path CE on the surface of the air conditioning case 10.

On the other hand, in the present embodiment, since the conductive path 100 is formed of a cured body obtained by curing a laminated body of conductive materials in which the conductive paths 100 are laminated several times, the conductive material is printed on the surface of the air conditioning case 10 or The influence of the surface tension of the conductive material during application can be suppressed.

For this reason, as shown in FIG. 4, the conductive path 100 of the present embodiment has a thickness Lt2 equivalent to the conductive path CE of the comparative example, and the width Lw2 of the conductive path 100 is the conductive path CE of the comparative example. The width Lw1 can be reduced.

Therefore, when the conductive path 100 of the present embodiment is formed for the air conditioning case 10, the surface of the air conditioning case 10 is compared with the case where the conductive path CE of the comparative example is formed for the air conditioning case 10. A region for forming the conductive path 100 can be reduced.

Furthermore, in the conductive path 100 of the present embodiment, irregularities are formed on a part of the surface in the process of laminating the conductive material. Specifically, the conductive path 100 according to the present embodiment has irregularities formed on the side surface standing on the surface of the air conditioning case 10.

For this reason, the conductive path 100 according to the present embodiment has sufficient surface area compared to the conductive path CE of the comparative example by forming irregularities on the surface. That is, the conductive path 100 of the present embodiment can improve heat dissipation during energization compared to the conductive path CE of the comparative example.

Next, a method for manufacturing the air conditioning unit 1 including the air conditioning case 10 having the conductive path 100 formed on the surface will be described. In this embodiment, after explaining the outline of the manufacturing process of the air conditioning unit 1, the manufacturing method of the conductive path 100 will be described.

In the manufacturing process of the air conditioning unit 1, first, a plurality of divided case bodies constituting the air conditioning case 10 are manufactured by injection molding or the like. In the next step, the conductive path 100 is formed at a predetermined location of the plurality of divided case bodies. In the next step, the air-conditioning case 10 is manufactured by fastening a plurality of divided case bodies with fastening elements such as screws and clips. And in the last process, components, such as the evaporator 14 and the heater core 15, are attached inside the air conditioning case 10.

In the present embodiment, the air conditioning unit 1 is manufactured by obtaining the above-described series of steps. In addition, the manufacturing process of the air-conditioning unit 1 of this embodiment is only an example, For example, a part of each process mentioned above may move back and forth.

Subsequently, a method for manufacturing the conductive path 100 will be described with reference to FIGS. 5 and 6. FIG. 5 is a block diagram showing the flow of the manufacturing process of the conductive path 100. FIG. 6 is an explanatory diagram for explaining the flow of the manufacturing process of the conductive path 100. FIG. 6 schematically shows the state of the conductive material and the like in each step shown in FIG. 5 and FIG. 6 exemplify the process when the conductive tree material is laminated five times on the surface of the air conditioning case 10, but the present invention is not limited to this. The number of times the conductive material is stacked can be appropriately changed according to the required thickness of the conductive path 100.

As shown in FIG. 5 and FIG. 6, in MP1, which is the first step, a conductive material having fluidity is supplied to the surface of the air conditioning case 10 (for example, the surface of the split case body). The conductive material is supplied by a technique such as printing or coating.

Here, the conductive material of the present embodiment is at least one conductive material among metal (for example, metal powder such as silver and lead), carbon (for example, carbon black), and conductive resin (for example, conductive polyacetylene). It is comprised with the solvent (namely, electrically conductive ink) containing the active substance. Thereby, the fluidity | liquidity of an electroconductive material is ensured.

Further, the conductive material of the present embodiment is composed of a conductive ink having photocurability that is cured by irradiation with light (that is, infrared rays, visible rays, and ultraviolet rays). Note that the conductive material may be formed of a paste-like material (that is, a conductive paste) containing at least one conductive substance among metal, carbon, and conductive resin.

Further, the conductive material of the present embodiment is made of a material that has good hydrophobicity with respect to the surface of the air conditioning case 10. Specifically, as shown by MP1 in FIG. 6, the conductive material of the present embodiment is made of a material whose contact angle θ1 is an obtuse angle when supplied to the surface of the air conditioning case 10. The contact angle θ may be adjusted by applying a water repellent treatment to the surface of the air conditioning case 10.

Furthermore, the conductive material of the present embodiment is made of a material having good hydrophobicity with respect to the surface of the cured conductive material. Specifically, as shown by MP3 in FIG. 6, the conductive material of the present embodiment is made of a material that has an obtuse angle of contact angle θ2 when supplied to the surface of the cured conductive material.

In MP2, which is the next step, the conductive material supplied to the surface of the air conditioning case 10 is cured by drying the solvent of the conductive material and sintering the conductive material by firing.

Specifically, in this step, the conductive material is irradiated with light having a predetermined wavelength. Thereby, a part of solvent evaporates and an electroconductive substance is condensed. Further, in this step, the temperature of the conductive material is raised to the temperature at which the conductive substance is sintered by irradiation with light. As a result, the conductive material has enhanced shape retention and conductivity by strengthening the bond between the conductive substances.

Here, the volume of the conductive material decreases with the volatilization of the solvent, so that its thickness becomes thinner than the thickness in MP1 in the previous step. Note that the conductive material has a thickness of about several μm to several tens of μm, for example, by this step.

In MP3, which is the next step, a conductive material is newly supplied to the surface of the conductive material supplied to the surface of the air conditioning case 10. Specifically, in this step, a conductive material is newly supplied to the surface of the conductive material cured in MP2 in the previous step. Note that the conductive material newly supplied in this step is made of a material equivalent to the conductive material supplied in the first step.

In the next step, MP4, the newly supplied solvent of the conductive material is dried and the conductive substance is sintered by firing. Thereby, the conductive material supplied to the surface of the already supplied conductive material is cured.

In subsequent steps, MP5, MP7, MP9, which are the same steps as MP3, and MP6, MP8, MP10, which are the same steps as MP4, are alternately repeated. That is, in the subsequent steps, the supply of the conductive material to the surface of the conductive material supplied to the surface of the air conditioning case 10 and the curing of the conductive material are repeated alternately. Through these steps, a conductive path 100 made of a laminate of conductive materials is formed on the surface of the air conditioning case 10.

And in MP11 which is the last process, the insulating material which has insulation with respect to the laminated body of an electroconductive material is supplied, and the surface of the laminated body of an electroconductive material is covered with the protective film 110. FIG. Thereby, corrosion of the conductive path 100, disconnection, a short circuit, etc. are suppressed.

Here, in the present embodiment, the contact angle θ1 between the conductive material and the air conditioning case 10 and the contact angle θ2 between the cured conductive material and the newly supplied conductive material are obtuse angles. For this reason, as for the conductive path 100 comprised with the laminated body of an electroconductive material, an unevenness | corrugation is formed in the side surface standingly arranged from the surface of the air-conditioning case 10.
