Description

Technical Field

[0001] This invention relates to vehicle exterior components such as car emblems, decorations, and logos that are installed on vehicles. Background Technology

[0002] Vehicle exterior parts having a substrate and a functional film are known. The substrate is formed from a resin material into a sheet shape and has a surface and a back side in the thickness direction. The functional film has a film body portion that is adhered to the surface or back side of the substrate. For example, Patent Document 1 describes a vehicle exterior part using a heating film with wiring for heating as a functional film.

[0003] The aforementioned vehicle exterior components are formed, for example, by an insert molding method using a functional film as an insert component. In this method, the functional film is disposed within a mold assembly. Molten resin material is filled into a cavity formed within the mold assembly by mold closing. The resin material is then cooled and solidified to form a substrate with the film body adhered to it. During substrate molding, the heat of the molten resin material melts the boundary portion of the film body relative to the substrate. Therefore, the film body is adhered to the substrate in a tight-fitting state.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2020-5057

[0005] However, vehicles equipped with exterior components are sometimes used in harsh environments such as heat and humidity. Therefore, for example, if the main body of the film repeatedly contracts and expands due to heat, the periphery of the main body may peel off from the substrate. This could lead to a deterioration in the appearance of the vehicle exterior components or water intrusion from the peeled areas. Summary of the Invention

[0006] The vehicle exterior component that solves the above problems includes: a substrate formed of resin material into a plate shape, having a surface and a back side on both sides in the thickness direction; and a functional film having a film body portion adhered to the surface or the back side of the substrate, the functional film also having an extension portion around the film body portion, an opening portion formed in the extension portion having an opening at least one side in the thickness direction of the extension portion, an extension processing portion formed of resin material being connected to the substrate, the extension processing portion having an engaging protrusion that engages with the opening portion when it is inserted into the opening portion.

[0007] According to the above structure, the extension portion is located around the main body of the film adhered to the surface or back of the substrate. The engaging protrusion of the extension processing portion, which is connected to the substrate, engages with the opening formed in the extension portion in the inserted state. Alternatively, the engaging protrusion is engaged with the opening. The main body of the film is held in close contact with the substrate by the opening and the engaging protrusion. Therefore, even if the main body of the film shrinks or expands due to heat, humidity, etc., it is not easily peeled off from the substrate.

[0008] Regarding the aforementioned vehicle exterior component, preferably, the extension processing part has a base on one side of the extension part in the thickness direction and on the side with the opening, the extension processing part is connected to the base material, and the engaging protrusion protrudes from the base in the thickness direction and engages with the opening.

[0009] According to the above structure, the base portion disposed on one side of the extension portion in the thickness direction is connected to the substrate and becomes stable. The engaging protrusion protrudes from the base portion in the thickness direction and engages with the opening portion. Therefore, the engaging protrusion can stably maintain its engagement with the opening portion, effectively preventing the film body portion from peeling off from the substrate.

[0010] Regarding the aforementioned vehicle exterior component, preferably, the opening is formed by a hole extending through the thickness direction of the extension, the opening is open at two faces of the extension in the thickness direction, the extension processing part has a cover on the opposite side of the base across the extension, and the engaging protrusion protruding from the base engages with the cover in a state of filling the hole.

[0011] According to the above structure, a covering portion disposed on the opposite side of the base, separated from the extension portion, covers the extension portion. Therefore, rainwater and the like are less likely to seep into the base side through the opening on the opposite side of the base of the extension portion. The water resistance of the extension portion is improved.

[0012] Regarding the aforementioned vehicle exterior components, preferably, the cover is composed of a component that is separate from the engaging protrusion, and the cover is formed of the same type of resin material as the engaging protrusion.

[0013] According to the above structure, the heat from the later-formed resin molding of the engaging protrusion and the cover portion, both made of the same type of resin material, easily melts the earlier-formed one. Therefore, the engaging protrusion and the cover portion are more firmly joined in a tighter fit.

[0014] Regarding the aforementioned vehicle exterior component, preferably, the opening is formed by a hole penetrating in the thickness direction of the extension portion, the opening is open at two faces in the thickness direction of the extension portion, the extension processing portion has a base on one side in the thickness direction of the extension portion, the extension processing portion is connected to the base material, a connecting hole is formed in the base material penetrating in the thickness direction of the base material and communicating with the hole, the extension processing portion has a pair of covering portions at the part where the extension portion and the base material are clamped from both sides in the arrangement direction of the extension portion and the base material, and the engaging protrusion connects the two covering portions in a state of engaging with the hole and the connecting hole.

[0015] According to the above structure, the base portion disposed on one side of the extension portion in the thickness direction becomes stable by being connected to the substrate. The engaging protrusion connects the pair of cover portions in a state of engaging with the hole in the extension portion and the connecting hole in the base portion. Therefore, the engaging protrusion can stably maintain its engagement with the opening portion, effectively preventing the film body portion from peeling off from the substrate.

[0016] Furthermore, a covering portion disposed on the opposite side of the base, separated from the extension portion, covers the extension portion. Therefore, rainwater and the like are less likely to seep into the base side through the opening in the side of the extension portion opposite to the base. The water resistance of the extension portion is improved.

[0017] Regarding the aforementioned vehicle exterior components, preferably, the openings are provided at multiple locations of the extension portion, the engaging protrusions are provided at multiple locations of the extension processing portion, and the engaging protrusions engage with the multiple openings.

[0018] According to the above structure, the engaging protrusion engages with the opening at multiple locations in the extension portion. Therefore, compared to the case where the engaging protrusion engages with the opening at only one location in the extension portion, the main body of the film is less likely to peel off from the substrate.

[0019] Regarding the aforementioned vehicle exterior components, preferably, the extension portion is disposed at multiple locations on the periphery of the main body of the film.

[0020] According to the above structure, engaging protrusions engage with openings at multiple locations on the periphery of the film body. Therefore, compared to the case where the engaging protrusion engages with the opening of the engaging protrusion at only one location on the periphery of the film body, the film body is less likely to peel off from the substrate.

[0021] Regarding the aforementioned vehicle exterior components, preferably, the functional film and the substrate are formed from the same type of resin material.

[0022] Based on the above structure, the heat generated during resin molding of the substrate allows for easy melting of the boundary portion of the film body relative to the substrate. Therefore, it is possible to obtain an exterior vehicle component in which the film body is adhered tightly to the substrate.

[0023] The effects of the invention

[0024] According to the aforementioned vehicle exterior component, the main body of the functional film can be prevented from peeling off from the substrate. Attached Figure Description

[0038] Below, refer to Figures 1 to 8 One embodiment of implementing an external component for a vehicle as a vehicle emblem installed at the front of the vehicle is described.

[0039] Furthermore, regarding the following description, the forward direction of the vehicle is defined as "forward" and the reverse direction as "rearward". Additionally, the up-down direction refers to the vertical movement of the vehicle, while the left-right direction is defined as the width of the vehicle and is consistent with the left-right direction when the vehicle is moving forward.

[0040] like Figure 3 As shown, a millimeter-wave radar device 13 for monitoring the front is disposed in the central part of the front of the vehicle 10 in the left-right direction and behind the front grille 11. The millimeter-wave radar device 13 has the function of transmitting millimeter waves of electromagnetic waves toward the front of the vehicle and receiving millimeter waves reflected by contact with objects outside the vehicle.

[0041] A window 12 is provided in front of the millimeter-wave radar device 13 on the front grille 11. The vehicle emblem 20 of this embodiment is disposed in the window 12. The vehicle emblem 20 has a substrate 21 and a functional film. In this embodiment, a heating film 31 is used as the functional film. Next, the components constituting the vehicle emblem 20 will be described.

[0042] <Substrate 21>

[0043] The substrate 21 forms the skeleton of the car logo 20. The substrate 21 is made of resin material, specifically PC (polycarbonate) resin in this embodiment, and is formed into a sheet shape. Figure 1 As shown, the substrate 21, when viewed from the front, is formed into an elliptical shape with a larger dimension in the left-right direction compared to the vertical direction. For example... Figure 3 As shown, the substrate 21 has a surface 22 and a back surface 23 on both sides in its thickness direction. In its upright state, the substrate 21 is configured such that its surface 22 faces the front of the vehicle 10 and its back surface 23 faces the rear of the vehicle 10. The substrate 21 is gently curved in a forward-bulging manner.

[0044] The substrate 21 is composed of a single layer with millimeter-wave transmittance. Alternatively, the substrate 21 may have a layered structure consisting of multiple layers, each with millimeter-wave transmittance, stacked in the front-to-back direction. Decorative layers may be included in the multiple layers.

[0045] Here, as Figure 1As shown, the radial direction of the substrate 21, close to the center O (the intersection of the major and minor axes), is called the "inner side," and the direction away from the center O is called the "outer side." Furthermore, the direction along the periphery of the substrate 21 is called the "circumferential direction."

[0046] Furthermore, mounting portions (not shown) for assembling the car emblem 20 to the front grille 11 or the body are provided at multiple locations on the outer periphery of the back surface 23 of the substrate 21. The mounting portions consist of clamping parts, small screws, and engaging claws.

[0047] <Heating film 31>

[0048] like Figure 2 As shown, the heating film 31 is used to add a snow-melting function to the car emblem 20. The heating film 31 is formed by wiring a heating wire (not shown) that is electrically heated on a thin film substrate (not shown) with millimeter-wave permeability. The thin film substrate is made of resin material, in this embodiment PC resin. The thin film substrate is formed into a shape corresponding to the surface 22 of the substrate 21, that is, a three-dimensional shape that is gently curved in a forward bulging manner.

[0049] like Figure 3 As shown, the heating film 31 has a film body portion 32 that is adhered to the surface 22 of the substrate 21. Similar to the substrate 21, the film body portion 32 is formed into an elliptical shape with a larger dimension in the left-right direction compared to the vertical direction.

[0050] The above describes the basic structure of the vehicle logo 20. Next, the characteristic parts of the vehicle logo 20 in this embodiment will be explained.

[0051] <Features>

[0052] like Figure 2 As shown, the heating film 31 has an extension 33 around the film body portion 32. The extension 33 is provided at multiple circumferentially separated locations on the periphery of the film body portion 32; in this embodiment, there are three locations. Each extension 33 extends outward from the periphery of the film body portion 32. Figure 4 As shown, each extension portion 33 extends rearward by bending along the periphery of the substrate 21.

[0053] At multiple locations of each extension portion 33, an opening 34 is formed, opening at least one surface of the extension portion 33 in the thickness direction. In this embodiment, the openings 34 are formed at two locations of the extension portion 33 that are separated from each other in the front-rear direction. Each opening 34 is constituted by a hole that extends through the extension portion 33 in the thickness direction. The opening shape of each opening 34 is formed as a rectangle that is elongated in the circumferential direction compared to the radial direction of the film body portion 32 (see reference). Figure 2Each opening 34 is located at two surfaces in the thickness direction of the extension 33.

[0054] An extended processing section 41, formed of resin material, is connected to the substrate 21. The extended processing section 41 has the same number as the extended section 33.

[0055] Each extended processing section 41 has a base 42 on one side of the extended section 33 in the aforementioned thickness direction, and on the side with the opening 34. The base 42 of each extended processing section 41 extends rearward from the periphery of the substrate 21. The front end 43 of the base 42 of each extended processing section 41 is connected to the periphery of the substrate 21.

[0056] Each expansion processing section 41 has engagement protrusions 44 at multiple locations therein, which engage with the opening 34 in a state of entering the opening 34. In this embodiment, the engagement protrusions 44 are formed at two locations on the base 42 that are separated from each other in the front-rear direction. Each engagement protrusion 44 protrudes from the base 42 in the thickness direction of the base 42.

[0057] The base 42 and engaging protrusion 44 of each extended processing section 41 are formed of resin material, specifically PC resin in this embodiment, and are integrally formed with the substrate 21. Each engaging protrusion 44 enters a corresponding hole and engages with the two openings 34. Each engaging protrusion 44 fills the hole.

[0058] Furthermore, each extended processing section 41 has a covering section 45 on the opposite side of the base 42, which in this embodiment is the radial side of the base 42 of the substrate 21, across the extended section 33. The extended section 33 and each engaging protrusion 44 that fills the aforementioned hole are engaged with the covering section 45.

[0059] Each extended processing section 41 has a cover 45 consisting of a component that is separate from the engaging protrusion 44. Each cover 45 is made of resin material, specifically PC resin in this embodiment.

[0060] like Figure 5 As shown, between adjacent base portions 42 in the circumferential direction of the substrate 21, a flange portion 46 extending circumferentially along the periphery of the substrate 21 is integrally formed relative to the base portion 42. The flange portion 46 protrudes rearward from the periphery of the substrate 21. The base portion 42 of each adjacent extended processing portion 41 in the circumferential direction of the substrate 21 is connected by the aforementioned flange portion 46. In addition, an auxiliary covering portion 47 is formed on the opposite side of the flange portion 46, across the periphery of the film body portion 32. The periphery of the film body portion 32 is covered by the aforementioned auxiliary covering portion 47. The auxiliary covering portion 47 is engaged with the flange portion 46.

[0061] Moreover, such as Figure 3As shown, the car logo 20 constructed in the above manner is positioned upright on the window 12 and mounted on the front grille 11 or the body at the mounting point.

[0062] Next, the operation of this embodiment configured as described above will be explained. Furthermore, the effects that accompany this operation will also be explained.

[0063] <(1) On the fabrication of thin film substrates>

[0064] (1-1) For example, the raw material (original plate) used to form the thin film substrate is trimmed by methods such as punching or laser cutting. This trimming is performed along the outer shape (outline) of the heating film 31 when it is flattened. In addition, at this time, the shape of the opening 34 is trimmed. A flat thin film substrate is obtained through the above trimming. Next, the thin film substrate is shaped into a three-dimensional shape by stamping, that is, it is bent so that the part corresponding to the film body 32 bulges forward and the part corresponding to the extension 33 extends backward. Thus, a thin film substrate with the target shape is obtained.

[0065] Alternatively, a thin film substrate can be fabricated using a method different from the one described above. For example, the raw material (original plate) used to form the thin film substrate is given an approximate three-dimensional shape corresponding to the heated thin film 31 by methods such as vacuum forming. The intermediate obtained by forming is then trimmed along the outer shape (outline) of the heated thin film 31, the shape of the opening 34, etc., by methods such as laser cutting. Thus, a thin film substrate with the target shape is obtained.

[0066] Furthermore, a thin film substrate can be manufactured according to the shape of the heating film 31 using the following method. The raw material (original plate) for forming the thin film substrate is trimmed along the outline (contour) of the heating film 31 and the shape of the opening 34 using methods such as punching or laser cutting. The trimmed intermediate is then given a three-dimensional shape using methods such as vacuum forming. This vacuum forming is performed while the portion corresponding to the opening 34 is sealed using tape or the like. Thus, a thin film substrate with the target shape is obtained.

[0067] In this embodiment, the opening 34 is formed by a hole through which the extension 33 passes in the thickness direction. Therefore, it is easier to punch compared to the case where the opening 34 is formed by a recess. The opening 34 can also be punched when trimming along the outer shape of the heating film 31. Therefore, the film substrate can be manufactured relatively simply and at low cost.

[0068] <(2) Molding of substrate 21 and extended processing section 41>

[0069] (2-1)Use Figure 6The mold assembly 51 shown performs resin molding (one-step molding) on ​​the substrate 21 and the base 42 of the extended processing section 41. The mold assembly 51 includes a fixed mold 52 and a movable mold 53, which approaches and separates from the fixed mold 52. The shaped heating film 31 is disposed in the fixed mold 52 as an insertion member. A cavity 54 is formed between the heating film 31, the fixed mold 52, and the movable mold 53 by closing the mold assembly 51. Figure 7 As shown, molten resin material (PC material) is filled into the cavity 54. The molten resin material also enters the opening 34 (hole) of the extension portion 33. The opening 34 (hole) is filled with the molten resin material. As described above, if the resin material filled into the cavity 54 and the opening 34 (hole) cools and solidifies, a substrate 21, a base 42, and an engaging protrusion 44 are formed.

[0070] Here, the same type of resin material (PC resin) is used for forming both the film body 32 and the substrate 21. Therefore, the heat generated during resin molding of the substrate 21 easily melts the boundary portion of the film body 32 relative to the substrate 21. Thus, an intermediate body 55 in which the film body 32 is tightly adhered to the substrate 21 can be obtained.

[0071] Furthermore, the same type of resin material (PC resin) is used for forming the extension portion 33, the base portion 42, and the engaging protrusion 44. Therefore, the heat generated during resin molding of the base portion 42 and the engaging protrusion 44 easily melts the boundary portion of the extension portion 33 relative to the base portion 42 and the engaging protrusion 44. Thus, it is possible to obtain an intermediate body 55 in which the extension portion 33 is adhered tightly to the base portion 42 and the engaging protrusion 44.

[0072] Furthermore, the intermediate body 55 is removed from between the fixed mold 52 and the movable mold 53 by opening the mold device 51.

[0073] (2-2) Next, using Figure 8 The mold assembly 61 shown performs resin molding (secondary molding) on ​​the cover portion 45. The mold assembly 61 includes: a fixed mold 62; and a movable mold 63, which approaches and separates from the fixed mold 62. The intermediate body 55 is disposed in the fixed mold 62 as an insert member. A cavity 64 is formed between the intermediate body 55 and the fixed mold 62 and movable mold 63 by closing the mold assembly 61. If molten resin material (PC resin) is filled into the cavity 64 and then cooled and solidified, the cover portion 45 is formed.

[0074] Here, the same type of resin material (PC resin) as the extension 33, base 42, and engaging protrusion 44 is used for forming the cover 45. Utilizing the heat from the later resin-molded cover 45, the extension 33, base 42, engaging protrusion 44, and cover 45 readily melt at their boundaries relative to the cover 45. Therefore, the extension 33, base 42, and engaging protrusion 44 are more firmly bonded to the cover 45 in a closer fit. This results in… Figure 4 The car logo shown is 20.

[0075] Furthermore, the mold device 61 is opened to remove the car logo 20 from between the fixed mold 62 and the movable mold 63.

[0076] <(3) Regarding the suppression of peeling of the film body 32 from the substrate 21>

[0077] (3-1) such as Figure 4 As shown, the extension portion 33 is located around the film body portion 32, which is adhered to the surface 22 of the substrate 21. The engaging protrusion 44 of the extension processing portion 41, which is connected to the substrate 21, engages with the opening 34 formed in the extension portion 33 in an engaged state. To rephrase, the engaging protrusion 44 engages with the opening 34. Therefore, the film body portion 32 is held in close contact with the surface 22 of the substrate 21 by the opening 34 and the engaging protrusion 44. Therefore, according to this embodiment, even if the film body portion 32 shrinks or expands due to heat, humidity, etc., peeling from the substrate 21 can be suppressed.

[0078] (3-2) In particular, in this embodiment, the base 42, which is disposed on one side of the extension portion 33 in the thickness direction, is connected to the substrate 21, thus providing stability. The engaging protrusion 44 protrudes from the base 42 and engages with the opening 34. Therefore, the engaging state between the engaging protrusion 44 and the opening 34 can be stably maintained. This effectively prevents the film body portion 32 from peeling off from the substrate 21.

[0079] (3-3) In this embodiment, the extension portion 33 is covered by a covering portion 45 disposed on the opposite side of the base portion 42, with respect to the extension portion 33. Therefore, rainwater and the like are less likely to seep into the base portion 42 through the opening 34 that opens at the surface of the extension portion 33 on the opposite side of the base portion 42. Thus, the water resistance of the extension treatment portion 41 can be improved. In addition, the peeling of the film body portion 32 from the substrate 21 can be further suppressed.

[0080] (3-4) In this embodiment, the opening 34 is provided at multiple locations (2 locations) of the extension portion 33, and the engaging protrusion 44 is provided at multiple locations of the base 42 of the extension processing portion 41. Furthermore, the corresponding engaging protrusion 44 engages with the multiple openings 34 of each extension portion 33 respectively.

[0081] Therefore, compared to the case where the engaging protrusion 44 engages with the opening 34 at one part of the extension 33, the film body 32 is less likely to peel off from the substrate 21.

[0082] (3-5) In this embodiment, the engaging protrusions 44 engage with the openings 34 at multiple locations (3 locations) of the extension portion 33 located on the periphery of the film body portion 32. Therefore, compared to the case where the extension portion 33 is located at only one location on the periphery of the film body portion 32 and the engaging protrusions 44 engage with the openings 34 of the extension portion 33, the film body portion 32 is less likely to be further peeled off from the substrate 21.

[0083] According to this embodiment, in addition to the effects described above, the following effects can be obtained.

[0084] <(4) Regarding the transmittance of millimeter waves>

[0085] If from Figure 3 The millimeter-wave radar device 13, as shown, transmits millimeter waves that pass through the vehicle emblem 20. After reflecting off objects in front of the vehicle, including other vehicles and pedestrians, the transmitted millimeter waves pass through the vehicle emblem 20 again and are received by the millimeter-wave radar device 13. Based on the transmitted and received millimeter waves, the millimeter-wave radar device 13 identifies objects and detects the distance and relative speed between the vehicle 10 and the object.

[0086] In this embodiment, the vehicle emblem 20 has millimeter-wave transmittance. Therefore, the vehicle emblem 20 is unlikely to obstruct the transmission of millimeter waves.

[0087] <(5) Regarding snow melting function>

[0088] (5-1) If ice and snow adhere to the emblem 20, primarily the exterior decorative surface (front surface), millimeter waves will attenuate, potentially reducing the detection performance of the millimeter-wave radar device 13. In this embodiment, the emblem 20 has a heating film 31. A heating wire of the heating film 31 is energized, causing it to heat up. A portion of the heat emitted by the heating wire is conducted to various parts of the emblem 20, including the exterior decorative surface. This heat can melt ice and snow adhering to the exterior decorative surface, or inhibit ice and snow from adhering to the exterior decorative surface, etc. As a result, the decrease in detection performance of the millimeter-wave radar device 13 due to ice and snow adhesion can be suppressed.

[0089] <(6) Regarding the appearance of the car logo 20>

[0090] (6-1) As explained in (3-1) above, in this embodiment, it is possible to suppress the peeling of the film body 32 from the substrate 21. Therefore, it is possible to suppress the decrease in the appearance of the logo 20 due to the peeling of the film body 32.

[0091] (6-2) such as Figure 4 As shown, in this embodiment, the extension portion 33 of the heating film 31 is located behind the peripheral edge of the film body portion 32. Additionally, the base portion 42 is located behind the peripheral edge of the substrate 21.

[0092] Therefore, when viewing the logo 20 from the front of the vehicle 10, the extension 33 and the base 42 are not easily visible. By providing the extension 33 and the extension processing part 41, the decline in the aesthetic appearance of the logo 20 can be suppressed.

[0093] Furthermore, the above-described embodiments can also be implemented as variations thereof, as described below. Within the scope of technical non-contradiction, the above-described embodiments and the following variations can be combined and implemented together.

[0094] <Regarding substrate 21>

[0095] ·exist Figure 1 In this embodiment, the shape of the substrate 21 viewed from the front can be changed to a shape different from that described above, such as a circle, a polygon, etc.

[0096] • The substrate 21 may be formed of a resin material different from that described in the above embodiments.

[0097] <Regarding Extended Processing Units 41 and 82>

[0098] Figures 9-13 This indicates a modification example of the extended processing units 41 and 82.

[0099] ·exist Figure 9 In the modified example, based on the aforementioned cover portion 45, the extension processing portion 41 has a cover portion 71 on the opposite side of the cover portion 45, separated by the extension portion 33, the base portion 42, and the engaging protrusion 44. The two cover portions 45 and 71 are connected by a connecting portion 72 formed at an adjacent location behind the base portion 42.

[0100] According to this modified embodiment, the covering portions 45 and 71 are inserted into the extension portion 33, the base portion 42, and the engaging protrusion 44 from both sides in the thickness direction of the base portion 42, etc. Therefore, compared with the above embodiment, the covering portion 45 is less likely to fall off from the extension portion 33, the base portion 42, and the engaging protrusion 44. It is possible to properly maintain the state in which the covering portion 45 covers the extension portion 33, the opening portion 34, the base portion 42, and the engaging protrusion 44.

[0101] ·exist Figure 10 In the modified example, the base 42 has a communicating hole 81 that extends through the thickness of the base 42 and communicates with the opening 34 formed by the aforementioned hole.
