Description

  The present invention relates to a method for manufacturing a resin door handle appearance part in a vehicle door handle for opening and closing a vehicle door from the outside of the vehicle, and a resin door handle appearance part.

  As shown in FIG. 1, a door handle for opening the door is attached to a door portion of a vehicle (automobile). When the user tries to open the door of the vehicle, the user grips the handle body constituting the door handle and raises it to the front side. As a result, the door locking mechanism is released, and when the handle body is raised as it is, the door is opened.

  Recently, door handles having a function called “smart entry (registered trademark)” have become widespread. A door handle having this function has a wireless transmission device in the handle body. Then, wireless communication is performed between the wireless transmission device and a wireless communication terminal (for example, a registered portable device) possessed by a user outside the vehicle, and the interior of the vehicle door mirror is provided, for example, according to the result of collating the codes of both. The wireless receiver that is installed sends a command to operate the door lock device built in the door, and prepares to lock and unlock the door. Thereafter, when the user touches a predetermined portion of the door handle, the door is locked / unlocked.

  Since the door handle is exposed to the outside of the vehicle, it is required to have a good design. For this reason, the surface of the door handle may be decorated in a metallic style. As a technique for decorating the surface of the door handle in a metallic style, for example, there is one disclosed in Patent Document 1. The present applicant has also applied for a door handle device (see Patent Document 2).

  Here, the technique of Patent Document 1 is to form a decorative film having a plating tone in advance and insert-mold it integrally on the surface of a base material (base of a door handle) inserted into a mold. . However, because the door handle is exposed to the outside of the vehicle, it is always affected by heat from sunlight such as ultraviolet rays and infrared rays, hydrolysis and erosion due to rainwater, etc., and the effects of material expansion and contraction due to temperature changes during the day and night. In addition, it is affected by moisture and oil such as sweat adhering to the user's hand and pressure when the user grips. Thereby, there exists a possibility that the decorating film of the door handle surface may deteriorate early.

  This invention is made | formed in view of the above malfunction, and makes it a subject to make it difficult to deteriorate the metallic decoration applied to the door handle.

The present invention for solving the above problems is as follows.
A method of manufacturing a resin door handle appearance part that forms an appearance of a vehicle door handle that is provided on a door of a vehicle and is operated at least during opening operation,
Etching process for forming fine irregularities by etching processing on the back surface which is the back side of the appearance surface of the translucent resin member injection-molded with a predetermined thickness in a form corresponding to the appearance. When,
A metal vapor deposition step of forming a metal vapor deposition film that can be seen through from the appearance surface side and allows the passage of communication radio waves on the back surface of the translucent resin member on which fine irregularities are formed by the etching step;
A plasma polymerization treatment step of forming a plasma polymerization film with an organosilicon compound monomer on the surface of the metal deposition film;
Etching process for forming fine irregularities by etching processing on the surface of the plasma polymerized film by the organosilicon compound monomer for the coating treatment planned later,

It is characterized by including.

In this invention, after the fine unevenness | corrugation by an etching process is formed in the back surface used as the back side of the external appearance surface of a translucent resin member, a metal vapor deposition film is formed in the back surface. With this metal vapor-deposited film, the appearance of the resin door handle exterior part is visually recognized in a metallic style. Moreover, since the metal vapor deposition film is provided on the back surface of the translucent resin member, it is difficult to be deteriorated or peeled off by rainwater, user sweat, or the like. In addition, since fine irregularities are formed on the back surface of the translucent resin member by etching to improve the adhesion to the metal vapor deposition film, a metal vapor deposition film should be formed directly on this surface (without base coating). The base coating process with poor yield can be omitted. This etching process can be performed by, for example, plasma or corona discharge.

Further, in the present invention, after a fine unevenness is formed by etching on the back surface which is the back side of the appearance surface of the translucent resin member, a metal vapor deposition film is formed on the back surface, and then plasma is formed on the surface of the metal vapor deposition film. A polymerized film is formed. After that, fine irregularities are formed by etching on the surface of the plasma polymerized film, and the surface is painted. By etching the surface of the plasma polymerized film, the hydrophilicity with the paint is improved, so that the paint is difficult to peel off. That is, since the metal vapor deposition film is doubly protected by the plasma polymerization film and the coating film, deterioration and peeling of the metal vapor deposition film can be prevented more reliably.

The present invention for solving the above problems is as follows.
A method of manufacturing a resin door handle appearance part that forms an appearance of a vehicle door handle that is provided on a door of a vehicle and is operated at least during opening operation,

  In this invention, after the fine unevenness | corrugation by an etching process is formed in the external appearance surface surface or back surface of a translucent resin member, a metal vapor deposition film is formed in the back surface, and a plasma polymerization film is formed on the surface of the metal vapor deposition film after that. It is formed. After that, fine irregularities are formed by etching on the surface of the plasma polymerized film, and the surface is painted. In the case of this invention, the metal vapor deposition film may be formed on either the external surface or the back surface (the surface that becomes the back side of the surface) of the translucent resin member.

In each of the above inventions,
The metal vapor deposition film is formed of a single metal or a metal vapor deposition portion containing a metal and a resin, and a plurality of microscopic metal vapor deposition blank portions or metal vapor deposition thin portions that allow the communication radio waves to pass therethrough are in the region of the metal vapor deposition portion. It is formed under the radio wave passing conditions in a distributed form. That is, the metal vapor deposition portion and the metal vapor deposition blank portion or the metal vapor deposition dilute portion are formed in a “sea island shape”. Examples of the metal having a sea-island shape include indium and tin.

  And the resin-made door handle appearance components are formed by each of the manufacturing methods described above.

(A) is a graph showing the specific volume-temperature curve of the amorphous resin, and (b) is a graph showing the specific volume-temperature curve of the crystalline resin.

  Hereinafter, embodiments of the present invention will be described in detail.

  In the present invention, FIG. 1 is a perspective view of a door handle 100, FIG. 2 is a front sectional view of the door handle 100, FIG. 3 is an exploded view, FIG. 4 is a flowchart showing a decoration process of the handle body 2, and FIG. FIG. 6 is an enlarged view of the metal vapor deposition film 18.

  First, the configuration of the door handle 100 will be described. As shown in FIGS. 1 and 2, the door handle 100 includes a handle body 2 mounted on a base member 1 mounted on a door (door panel) of a vehicle (not shown), and the handle body 2 from the surface (that is, outside the vehicle). Cover body 3 (door handle exterior part) covering. Both the handle main body 2 and the cover body 3 are manufactured by injection molding a thermoplastic resin material. Hereinafter, the side outside the vehicle (outside surface) with respect to the door of the vehicle is referred to as “front surface”, and the side inside the vehicle (inside surface) is referred to as “back surface”.

  The handle body 2 will be described. The handle body 2 is a portion that is gripped by a hand when the user opens the door. The handle body 2 has a curved and elongated grip portion 4 and an end portion in the longitudinal direction of the handle body 2 so as to have a good feeling when gripped. Rotating as a fulcrum when the door handle 100 mounted on the base member 1 is raised to the near side, protruding from the inner surface side (side facing the base member 1) (left end portion in the drawing view of FIG. 2). The fulcrum part 5 and the other end part of the handle body 2 in the longitudinal direction (the right end part in the drawing in FIG. 2) protrude toward the back surface and guide the rotation when the door handle 100 is raised to the near side. And a motion guide unit 6. The distal end portion of the rotation guide portion 6 is bent in an L shape toward the rotation fulcrum portion 5, and a stopper portion 7 is formed at the bent portion. When the door handle 100 is raised by the user, the door handle 100 is rotated in the direction of the arrow 8 around the rotation fulcrum C provided at the tip of the rotation fulcrum portion 5 of the handle body 2. And if it rotates more than a fixed angle, the stopper part 7 of the rotation guide part 6 will contact | abut to the base member 1, and the further rotation will become impossible. FIG. 1 shows a state in which the door handle 100 is raised to the near side.

  The grip portion 4 of the handle body 2 is provided with an elongated recess 9 that opens toward the surface. A wireless communication device 11 that transmits radio waves toward the outside of the vehicle is fixed to the bottom surface of the recess 9 by a predetermined fixing means (for example, a double-sided tape 12). In addition to smart entry, this wireless communication device may be an external wireless communication unit (for example, a fixed wireless communication base similar to ETC (registered trademark)).

  On the back surface of the grip portion 4 of the handle body 2, a recess portion 13 is provided to improve the feeling when the user grips the door handle 100. In addition, a hole 14 is provided in a portion on the left side of the recess 9 in the grip 4, and a finger detection device 15 that detects that a user's finger has touched the door handle 100 is disposed in the hole 14. The Further, a portion of the grip portion 4 on the right side of the concave portion 9 is notched to form a notch portion 16, and a user locks the door by a vehicle key (not shown) in the notch portion 16. A cylinder lock 17 is provided for unlocking.

  The cover body 3 will be described. As shown in FIGS. 2 and 3, the cover body 3 has a thin ship bottom shape corresponding to the grip portion 4 of the handle body 2. And it attaches to the handle | steering-wheel main body 2 in the form which covers the whole surface of the grip part 4 from the near side. As a result, the opening of the recess 9, the hole 14, and the notch 16 of the handle body 2 are covered, and the wireless communication device 11, the finger detection device 15, and the cylinder lock 17 attached to these portions are protected from rainwater and the like. Is done. Further, both side wall portions of the cover body 3 are cut out in a curved shape so as to correspond to the recessed portions 13 of the grip portion 4. Thereby, the feeling when the user grips the door handle 100 (the handle body 2 with the cover body 3 attached) is improved.

  Next, a decorating process for decorating the entire surface of the door handle 100 in a metallic style will be described. FIG. 4 shows a flowchart of the decoration method. First, a method for decorating the handle body 2 will be described, and then a method for decorating the cover body 3 will be described.

  First, a thermoplastic resin material (for example, polycarbonate) is injection-molded to produce a base body (handle base body 2 ') of the handle body 2 (step S1). Hereinafter, the decorated handle body 2 (having a metallic decoration) and the handle base 2 '(having no metallic decoration) may be described without distinction.

  Next, a predetermined metal is vapor-deposited on the surface of the handle base 2 '(metal vapor deposition step, step S2). As a result, as shown in FIG. 5, the surface of the handle base 2 ′ is covered with the metal vapor deposition film 18. The metal deposited on the surface of the handle base 2 'in this step is indium or tin. Both indium and tin are glossy silver-gray metals that are deposited on the handle substrate 2 'in a “sea-island structure”. As shown in FIG. 6, the sea-island structure means that indium or tin metal particles have an island-like discontinuous structure with respect to composition, thickness, density or distribution, etc. A sea-like portion 21 that allows the passage of is formed. The thickness of the island portion is several nm to several tens of nm. Radio waves transmitted from the wireless communication device 11 (see FIG. 2) can pass through the sea-like portion of the metal vapor deposition film 18 of the handle base 2 '. Moreover, the surface of the handle base 2 ′ exhibits a metallic luster and a metallic color (silver gray) due to the metal vapor deposition film 18 of indium or tin. That is, the handle base 2 'is decorated in a metallic style.

Metal deposition on the handle base 2 'is performed in a vacuum vessel (chamber 22) that has been depressurized to a predetermined pressure. As shown in FIG. 7, the handle base 2 ′ is accommodated in the vapor deposition chamber 22 and arranged in a suspended state on the support plate 23. The support plate 23 is grounded. A crucible 24 that accommodates a metal (for example, indium) to be deposited is disposed immediately below the support plate 23 in the chamber. A heater 25 for heating is attached to the crucible 24. In order to deposit indium on the handle base 2 ′, the inside of the chamber 22 is reduced to a predetermined pressure (about 10 ⁻³ to 10 ⁻² Pa) by the vacuum pump 26, the heater 25 is operated, and the indium in the crucible 24 is removed. Heat to melting point (about 167 ° C) or higher. Thereby, indium evaporates (vaporizes) and is blown toward the handle base 2 '. Indium adhering to the handle base 2 'is cooled after a predetermined time, and a thin metal deposition film 18 (see FIG. 5) of indium is formed on the surface of the handle base 2'. The thickness of the metal vapor deposition film 18 is about 50 nm (500 mm). In FIG. 7, reference numeral 27 denotes a high frequency power source for heating the heater 25.

  Next, as shown in FIG. 4, the surface of the handle base 2 ′ covered with the metal vapor deposition film 18 is coated (top coating) (painting step, step S <b> 3). This is because the door handle 100 is always exposed to the outside of the door and exposed to rainwater and the like, so that the metal vapor deposition film 18 is protected from rainwater and the weather resistance is improved. In the case of the present embodiment, transparent acrylic urethane (polyurethane resin paint) is coated on the surface of the handle base 2 'to form a transparent coating film 28 (see FIG. 5). As a result, the surface strength of the handle main body 2 is increased while the entire surface of the handle main body 2 is decorated in a metallic style. For example, the double-sided tape 12 (see FIG. Even if it is peeled off, there is no possibility that the metal vapor deposition film 18 will peel off.

  In the decoration method of the above-described embodiment, the metal vapor deposition film 18 is formed directly on the surface of the handle base 2 '. Conventionally, when a metal is vapor-deposited on the surface of the handle base 2 ', a base coating is applied to the surface in order to improve the adhesion of the metal. However, there is a possibility that the resin of the paint enters the metal vapor deposition film to deteriorate the texture of the metal vapor deposition film, or a foreign matter such as dust accompanying the coating enters. In addition, the yield of paint is poor, leading to increased costs. For this reason, it is desirable to deposit metal directly on the surface of the handle base 2 '(direct vapor deposition). When metal was directly deposited on the surface of the handle base 2 ′, the surface of the handle base 2 ′ (the part excluding the rotation fulcrum portion 5 and the rotation guide portion 6) was modified in order to ensure metal adhesion. It is desirable to perform metal deposition later. In this case, as shown in FIG. 4, a surface modification process is inserted between the injection molding process (step S1) and the metal vapor deposition process (step S2). The surface modification is performed by, for example, etching (etching process, step S4), corona discharge, or the like. In this embodiment, this etching is performed by plasma processing using oxygen in the air as a discharge gas (plasma etching). As shown in FIG. 8, two electrodes (an upper electrode 31 and a lower electrode 32) are arranged in parallel in a chamber 29. The inside of the chamber 29 is reduced to a predetermined pressure by the vacuum pump 33, and an etching gas (in this case, air indicated by an arrow 30) is sent in. In this state, when a high frequency voltage is applied to one (lower) electrode 32 by the high frequency power source 34, oxygen in the air in the chamber 29 becomes plasma and is applied to the handle base 2 ′ installed on the lower electrode 32. The time required for the etching process is about 120 seconds. As a result, the surface of the handle base 2 ′ is modified to improve the adhesion to the metal vapor deposition film 18, and foreign matters such as dust and dirt attached to the surface of the handle base 2 ′ are removed and cleaned. It becomes.

  Then, as shown in FIG. 4, it is desirable to form a plasma polymerization film 35 (see FIG. 9) on the surface of the handle body 2 in order to protect the metal vapor deposition film 18 of the handle base 2 '(plasma polymerization process). Step S5). Plasma polymerization is performed in a vacuum chamber as in the plasma etching process and metal deposition. In the case of the present embodiment, the organosilicon compound monomers (for example, hexamethyldisiloxane monomer) are heated in the vacuum chamber to plasma polymerize them to form the plasma polymerized film 35. As a result, a plasma polymerization film 35 of several nm (several tens of millimeters) is formed on the surface of the handle body 2 and covers the metal vapor deposition film 18. The time required for the plasma polymerization process is about 180 seconds.

  Furthermore, as shown in FIG. 4, it is desirable to modify the surface of the handle base 2 'on which the plasma polymerized film 35 is formed. This surface modification is performed by etching, corona discharge or the like (etching in the present embodiment) as in the case of the surface modification of the handle base 2 'described above (etching step, step S6). This is because the plasma-polymerized film 35 made of hexamethyldisiloxane has hydrophobicity and it is difficult to perform uniform coating as it is, so that the compatibility with the coating is improved when coating is performed in the next step. In this etching process (step S6), the same process as the etching process (step S4) described above is performed.

  Next, the case where the cover body 3 of the door handle 100 is decorated in a metallic style will be described. Since the action when decorating the surface of the cover body 3 in a metallic style or performing the etching process is exactly the same as the case of the handle body 2 described above, here the back surface (inner side surface) of the cover body 3 The process in the case of decorating with a metallic tone will be described. The cover base 3 ′ of the cover body 3 is formed by injection molding a transparent thermoplastic resin material (transparent resin material). FIG. 10A shows a state in which the back surface of the cover base 3 ′ is vapor-deposited, and FIG. 10B shows a state in which the metal vapor deposition film 18 formed on the back surface of the cover base 3 ′ is etched. Note that the surface (outer surface) of the cover base 3 ′ is masked in order to deposit metal on the back surface of the cover base 3 ′.

  In the first method of decorating the surface of the cover body 3 in a metallic style, first, the back surface of the cover base 3 ′ is etched (step S4; FIG. 10B), and the etched surface (cover base). A metal vapor-deposited film 18 is formed on the back surface 3 ′ (step S2, FIG. 10A). As described above, indium (or tin) is vapor-deposited after forming fine irregularities on the back surface of the cover substrate 3 ′ by performing etching rather than directly depositing metal on the back surface of the cover substrate 3 ′. It is desirable to make it. Since the cover base 3 ′ is made of a transparent thermoplastic resin material, the cover body 3 that is decorated in a metallic tone in appearance is formed.

  In the case of the cover body 3 of the present embodiment, a metal vapor deposition film 18 is formed on the back surface thereof. For this reason, even if the user grips the cover body 3 and the cover body 3 is rubbed or rainwater or the like adheres to the surface of the cover body 3, it does not affect the metal deposition film 18. However, it is desirable to apply a transparent paint on the surface of the cover body 3 (step S3, second method). Thereby, the intensity | strength of the surface of the cover body 3 can be made high, without impairing metallic decoration or impeding passage of a communication radio wave.

  Further, a plasma polymerization film 35 may be formed on the surface of the metal vapor deposition film 18 formed on the back surface of the cover base 3 '(step S5). Thereby, the metal vapor deposition film 18 is protected, and even if the cover body 3 is used for a long period of time, the metal vapor deposition film 18 is hardly peeled off (third method).

  Further, a transparent paint may be applied to the plasma polymerization film 35 formed by the third method described above (step S3, fourth method). Since the plasma polymerized film 35 has hydrophobicity, it is desirable that the surface of the plasma polymerized film 35 is etched (step S6) to improve the affinity with the paint.

  The first to fourth methods described above are cases where the metal vapor deposition film 18 is formed on the back surface of the cover base 3 '. However, it is also possible to form the metal vapor-deposited film 18 on the surface of the cover substrate 3 ', form the plasma polymerized film 35 on the surface, and / or apply the coating (fifth method).

  In the cover body 3 of the present embodiment, a metal vapor deposition film 18 is formed on the back surface thereof. Thereby, even if rainwater flows over the surface of this cover body 3 over a long period of time or is gripped by the user, the portion that contacts the rainwater or the user's finger is always the surface of the cover body 3. The metal vapor deposition film 18 does not peel off or deteriorate. For this reason, it becomes unnecessary to form the coating film 28 on the surface of the metal vapor deposition film 18 on the back surface of the cover body 3, and the process can be greatly omitted. Moreover, since the cover body 3 is made of a transparent resin material, the surface of the cover body 3 on which the predetermined metal vapor deposition film 18 such as indium or tin is formed on the back surface is visually recognized from the outside in a metallic style, so that the design is good. It becomes. In addition, although it is desirable to form this metal vapor deposition film 18 on the back surface of the cover body 3, you may form it on the surface.

  The cover body 3 of the door handle 100 of the present embodiment is molded from a thermoplastic resin (for example, polycarbonate, polymethyl methacrylate resin) having a light transmittance of 80% or more in order to improve the appearance after molding. In addition to the above-described thermoplastic resin, amorphous nylon (amorphous polyamide) can be used. Since amorphous nylon has a light transmittance of 86% or more, it has a high light transmittance and excellent gloss as well as polycarbonate and polymethyl methacrylate resin. In addition, there are advantages that the solvent resistance and weather resistance are higher than those of polycarbonate, and that the impact resistance and heat resistance are higher than that of the polymetal acid methyl resin (the heat resistance temperature of the polymetal acid methyl resin is 60 to 80 ° C.). Amorphous nylon is commercially available, for example, under the trade name “Grillamide (registered trademark)”. Table 1 shows the properties (mechanical properties, thermal properties, electrical properties, etc.) of Grillamide TR90.

  Further, FIG. 11A shows a specific volume-temperature curve of the amorphous resin, and FIG. 11B shows a specific volume-temperature curve of the crystalline resin. Here, Tg is a glass transition point and Tm is a melting point. In the case of amorphous resin, the specific volume (reciprocal of density) increases at a constant rate even after exceeding Tg. On the other hand, the specific volume of the crystalline resin increases abruptly just before Tm. This is because the amount of shrinkage accompanying the temperature change of the crystalline resin is much larger than that of the amorphous resin (in other words, the amount of shrinkage accompanying the temperature change of the amorphous resin is much smaller than that of the crystalline resin). It means that.
