Description

Technical Field

[0001] The present invention relates to a resin molded article used for fixing to a plate-shaped component formed in the form of a plate. Background Technology

[0002] For example, in vehicles equipped with head-up displays, resin molded parts are sometimes used to attach to the dashboard, which is a panel-like component. The resin molded part is positioned above the head-up display, covering a portion of the opening formed in the dashboard.

[0003] Not limited to the cover of a head-up display device, various resin molded articles used for fixing to plate-like components are known. As prior art related to such resin molded articles, there is technology disclosed in Japanese Patent Application Publication No. 2000-177523. Referring to this application… Figure 7A The resin molded articles disclosed in Japanese Patent Application Publication No. 2000-177523 will be described.

[0004] The resin molded article 120, which serves as a cover for an airbag device, is fixed to the dashboard, which is a plate-shaped component 111. The front edge 140 of the resin molded article 120 is formed in a generally U-shape that opens forward. The resin molded article 120 is fixed to the plate-shaped component 111 by clamping the end 111c of the plate-shaped component 111 using the generally U-shaped front edge 140. Summary of the Invention

[0005] In addition, in order to fix the resin molded article 120 in the appropriate position relative to the plate-shaped component 111, the position and size of the leading edge portion 140 of the resin molded article 120 are adjusted during the design phase.

[0006] Reference Figure 7B . Figure 7B This diagram illustrates the method for adjusting the leading edge portion. When designing the resin molded article 120, a manufacturing mold for the resin molded article 120 is first manufactured such that the leading edge portion 140 is formed smaller than intended. Then, in order to position the leading edge portion 140 appropriately relative to the plate-shaped member 111, corresponding portions of the manufacturing mold are gradually removed. By removing the manufacturing mold, the shape of the leading edge portion 140 changes with the amount removed. Consequently, the point where the leading edge portion 140 abuts against the plate-shaped member 111 changes, and this adjustment is repeated until the resin molded article 120 is fixed in the appropriate position.

[0007] At this time, the lower surface 141 of the leading edge 140 is inclined relative to the end 111c of the plate-shaped member 111. When adjusted in a manner that raises the lower surface 141 of the leading edge 140, the position of the resin molded article 120 relative to the plate-shaped member 111 varies in two directions: along the surface of the plate-shaped member 111 and perpendicular to that surface. Even if the mounting position of the resin molded article 120 is optimal relative to the direction along the surface of the plate-shaped member 111, it is possible that the mounting position is not optimal relative to the direction perpendicular to the surface. It is desirable to be able to fix the resin molded article 120 in the optimal position relative to the plate-shaped member 111.

[0008] The objective of this disclosure is to provide a resin molded article that can be fixed in a desired position relative to a plate-shaped component.

[0034] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the description, left and right refer to left and right relative to the occupants of the vehicle carrying the resin molded article, and front and back refer to front and back relative to the vehicle's direction of travel. Additionally, in the figures, Fr represents front, Rr represents rear, Le represents the left of the occupant, Ri represents the right of the occupant, Up represents up, and Dn represents down.

[0035] <Example>

[0036] The embodiments are described with reference to the accompanying drawings.

[0037] Reference Figure 1 The resin molded article 20 is, for example, mounted on a vehicle 10. More specifically, the resin molded article 20 is used by fixing it to a dashboard 11 located at the front of the vehicle compartment. A head-up display 12 capable of emitting light is provided below the resin molded article 20.

[0038] The instrument panel 11 is a resin component formed in the shape of a plate, and can also be referred to as a plate-shaped component 11. Furthermore, the plate-shaped component 11 can simply be a plate-shaped component capable of fixing the resin molded article 20. Therefore, in addition to resin, any material such as metal can be used for the plate-shaped component.

[0039] Light emitted from the head-up display 12 can be projected onto the windshield, for example. By visually observing the light projected onto the windshield, occupants can obtain information such as the vehicle's speed. Furthermore, light emitted from the head-up display 12 can also be projected onto a projection unit called a synthesizer.

[0040] Reference Figure 2 and Figure 3 The resin molded article 20 is formed by injection molding. The resin molded article 20 is fixed to the edge of the plate-shaped member opening 11a in the plate-shaped member 11.

[0041] The resin molded article 20 has: a frame-shaped main body 30 that is generally rectangular, an abutment support 23 that protrudes from the front of the main body 30 along the plate-shaped member 11, and a rear locking part 24 formed at the rear of the main body 30 and attached to the edge of the opening 11a of the plate-shaped member.

[0042] Reference Figure 4The resin molded article 20 further includes: an upper surface abutting portion 26 extending from the main body portion 30 to the upper surface 11b of the plate-shaped member 11 and capable of abutting against the upper surface 11b of the plate-shaped member 11; an end surface abutting portion 27 protruding upward from the rear portion of the abutting portion support portion 23 and capable of abutting against the end face 11c of the opening portion 11a of the plate-shaped member; and a lower surface abutting portion 28 protruding upward from the front end of the abutting portion support portion 23 and capable of abutting against the lower surface 11d of the opening portion 11a of the plate-shaped member.

[0043] Refer to together Figure 3 The main body 30, the abutment support 23, the rear locking part 24, the upper surface abutment part 26, the end face abutment part 27, and the lower surface abutment part 28 are integrally formed.

[0044] Reference Figure 2 The main body 30 is constructed by connecting four peripheral wall portions 31 to 34 in a generally rectangular shape. The peripheral wall portions 31 to 34 include: a front wall portion 31 formed at the front and extending vertically, a left wall portion 32 extending rearward from the left end of the front wall portion 31, a right wall portion 33 extending rearward from the right end of the front wall portion 31, and a rear wall portion 34 extending horizontally to connect the rear ends of the left wall portion 32 and the right wall portion 33.

[0045] The lower ends of the peripheral wall portions 31-34 are provided with openings 35 through which light emitted from below can pass. The upper ends of the peripheral wall portions 31-34 are provided with upper surface portions 36 formed in a frame shape.

[0046] The front wall portion 31 is rectangular in shape, longer in the left and right directions. The left wall portion 32 and the right wall portion 33 are trapezoidal with roughly parallel top and bottom edges. The rear edges of the left wall portion 32 and the right wall portion 33 slope so that their lower ends are positioned further forward than their upper ends. The rear wall portion 34 is roughly rectangular in shape when viewed from above. Furthermore, the rear wall portion 34 slopes downwards towards the front, and the rear part of the rear wall portion 34 curves upwards from the center in the front-to-back direction.

[0047] Reference Figure 2 The abutment support 23 is divided into three sections spaced apart in the left-right direction of the main body 30. (See reference...) Figure 4 A portion of the abutment support portion 23 is connected to the back side of the main body portion 30. A gap Sp is formed between the abutment support portion 23 and the upper surface abutment portion 26. A portion of the abutment support portion 23 is located below the upper surface abutment portion 26.

[0048] Reference Figure 5 The abutment support portion 23 has: a support body 23a that protrudes forward from the body portion 30; and a side wall portion 23b that rises from the body portion 30 and closes one side of the support body 23a.

[0049] Reference Figure 3 The rear locking portion 24 includes: a rear first abutting portion 24a, which extends along the upper surface 11b of the plate-shaped member 11 and abuts against the upper surface 11b of the plate-shaped member 11; and a rear second abutting portion 24b, which abuts against the end face 11c of the opening portion 11a of the plate-shaped member.

[0050] The rear first abutment portion 24a is formed at an angle relative to the upper surface portion 36. As a result, the end face of the rear first abutment portion 24a abuts against the upper surface 11b of the plate-shaped member 11, which cannot be visually confirmed from the outside.

[0051] Reference Figure 4 The upper surface abutment portion 26 connects to the upper surface 11b of the plate-shaped member 11 from the main body portion 30, and is inclined relative to both the main body portion 30 and the upper surface 11b of the plate-shaped member 11. The end face of the upper surface abutment portion 26 abuts against the upper surface 11b of the plate-shaped member 11, and cannot be visually confirmed from the outside.

[0052] The front end of the upper surface contact portion 26 is formed as a thin wall, and the thin-walled portion abuts against the upper surface 11b of the plate-shaped member 11.

[0053] An end-face abutment portion 27 is formed at a position covered by the main body portion 30 and / or the upper surface abutment portion 26. The end-face abutment portion 27 includes an end abutment surface 27a capable of abutting against the end face 11c of the plate-shaped member 11. The end abutment surface 27a is formed along the end face 11c of the plate-shaped member 11. That is, the end abutment surface 27a is arranged in a direction substantially the same as the end face 11c of the plate-shaped member 11. The end abutment surface 27a preferably makes line contact or surface contact with the end face 11c of the plate-shaped member 11.

[0054] The end face abutment portion 27 is formed in the abutment portion support portion 23 at a position overlapping with the side wall portion 23b. The end face abutment portion 27 is formed to be coplanar with the side wall portion 23b.

[0055] The position of the end abutment surface 27a can be adjusted by removing material from the molding die. By removing material from the molding die, the end abutment surface 27a can be positioned further forward. By adjusting the position of the end abutment surface 27a, the position of the resin molded article 20 in the front-rear direction can be adjusted.

[0056] The lower surface abutment portion 28 is formed on the outer side of the area covered by the upper surface abutment portion 26, and is separated from the end face abutment portion 27. The lower surface abutment portion 28 includes a lower abutment surface 28a capable of abutting against the lower surface 11d of the plate-shaped member 11. The lower abutment surface 28a is formed on a surface substantially perpendicular to the end face abutment surface 27a. The lower abutment surface 28a is formed at the highest point of the lower surface abutment portion 28.

[0057] The lower surface abutment portion 28 is formed in the abutment portion support portion 23 at a position overlapping with the side wall portion 23b. The lower surface abutment portion 28 is formed to be coplanar with the side wall portion 23b.

[0058] The position of the lower abutment surface 28a can be adjusted by removing material from the molding die. By removing material from the molding die, the lower abutment surface 28a can be positioned higher. By adjusting the position of the lower abutment surface 28a, the vertical position of the resin molded article 20 can be adjusted.

[0059] Furthermore, the end face contact portion 27 and the lower surface contact portion 28 can also protrude directly from the main body portion 30 without passing through the contact portion support portion 23.

[0060] Next, the method for installing the resin molded article 20 to the plate-shaped component 11 described above will be explained.

[0061] Reference Figure 6A and Figure 6B First, as indicated by arrow 41, the end face 11c of the plate-shaped member 11 is aligned with the gap Sp between the upper surface abutment portion 26 and the abutment portion support portion 23. After aligning with the gap Sp, as indicated by arrows 42 and 43, the resin molded article 20 is rotated while sliding forward, causing the upper surface abutment portion 26 to abut against the upper surface 11b of the plate-shaped member 11. The resin molded article 20 is then slid forward until the end abutment surface 27a abuts against the end face 11c of the plate-shaped member 11. At this time, the rear locking portion 24 (see reference...) Figure 3 Pressing downwards, the rear of the resin molded article 20 is fixed, and the lower surface abutment portion 28 abuts against the lower surface 11d of the plate-shaped component 11. By abutting the upper surface abutment portion 26, the end face abutment portion 27, and the lower surface abutment portion 28 against the plate-shaped component 11, the resin molded article 20 can be fixed in the correct position on the plate-shaped component 11.

[0062] The above description of the resin molded article 20 is summarized.

[0063] Reference Figure 4 The resin molded article 20 is fixed to the plate-shaped component 11 and used. In addition, the resin molded article 20 has integrally formed on the main body 30 an upper surface abutment portion 26 that can abut against the upper surface 11b of the plate-shaped component 11; an end surface abutment portion 27 that can abut against the end face 11c of the plate-shaped component 11; and a lower surface abutment portion 28 that is formed separately from the end surface abutment portion 27 and can abut against the lower surface 11d of the plate-shaped component 11.

[0064] The resin molded article 20 includes: an end face abutment portion 27 that abuts against the end face 11c of the plate-shaped member 11; and a lower surface abutment portion 28 formed separately from the end face abutment portion 27 and capable of abutting against the lower surface 11d of the plate-shaped member 11. The end face abutment portion 27 abutting against the end face 11c of the plate-shaped member 11 and the lower surface abutment portion 28 abutting against the lower surface 11d are respectively provided. Therefore, the resin molded article 20 can be fixed in optimal positions relative to the end face 11c and the lower surface 11d of the plate-shaped member 11. That is, a resin molded article 20 that can be fixed in a desired position relative to the plate-shaped member 11 can be provided.

[0065] The end abutment surface 27a of the end face abutment portion 27, which abuts against the end face 11c of the plate-shaped member 11, is arranged in a direction substantially the same as the end face 11c of the plate-shaped member 11. This ensures that the abutment surface is large enough to reliably fix the resin molded article 20 in the desired position.

[0066] The lower abutment surface 28a of the lower surface abutment portion 28, which abuts against the lower surface 11d of the plate-shaped member 11, is formed on a surface substantially perpendicular to the end abutment surface 27a. This allows the lower abutment surface 28a to also make linear contact with the lower surface 11d of the plate-shaped member 11. This enables the resin molded article 20 to be more reliably fixed in the desired position.

[0067] An end-face abutment portion 27 is formed at a position covered by the upper surface abutment portion 26. Furthermore, a lower surface abutment portion 28 is formed outside the area covered by the upper surface abutment portion 26. By forming the end-face abutment portion 27 at a position covered by the upper surface abutment portion, the end-face abutment portion 27 is not exposed to the outside, thus ensuring a good appearance for the resin molded article 20. Additionally, by forming the lower surface abutment portion 28 outside the area covered by the upper surface abutment portion 26, a larger gap Sp is ensured, facilitating the installation of the resin molded article 20 onto the plate-shaped member 11. Moreover, since the lower surface abutment portion 28 is the portion that abuts against the lower surface 11d of the plate-shaped member 11 and is covered by the plate-shaped member 11, its appearance is not compromised even though it is formed outside the area covered by the upper surface abutment portion 26.

[0068] It also has an abutment support portion 23 protruding from the main body portion 30 along the plate-shaped member 11. Furthermore, an end face abutment portion 27 and a lower surface abutment portion 28 are formed on the outer surface of the abutment support portion 23. By forming the abutment support portion 23, the support rigidity of the end face abutment portion 27 and the lower surface abutment portion 28 can be improved, and the end face abutment portion 27 and the lower surface abutment portion 28 can be made smaller. By making the end face abutment portion 27 and the lower surface abutment portion 28 smaller, the adjustment operation becomes easier, and the manufacturing cost of the resin molded article 20 can be reduced.

[0069] The upper surface abutment portion 26 is connected from the main body portion 30 to the upper surface 11b of the plate-shaped member 11 and is inclined relative to the main body portion 30. This makes the end of the upper surface abutment portion 26 invisible from the outside, which can further improve the appearance of the resin molded article 20 and also increase the degree of design freedom.

[0070] Reference Figure 3 An opening 35 is provided in the main body 30 to allow light emitted from below to pass through. Furthermore, the opening 35 is surrounded by peripheral wall portions 31 to 34 extending in the vertical direction. When allowing emitted light to pass through, it is particularly desirable to position the resin molded article 20 in the correct position relative to the light-emitting device (e.g., head-up display 12). The resin molded article 20 is particularly preferred as it can be fixed relative to the plate-shaped member 11 in a desired position.

[0071] Reference Figure 4 The end face abutment portion 27 and the lower surface abutment portion 28 are formed to be coplanar with the side wall portion 23b. As a result, it is easy to adjust the shape of the end face abutment portion 27 and the lower surface abutment portion 28.

[0072] Furthermore, regarding the application of the resin molded article, it is not limited to vehicle interiors as long as it is fixed to a plate-like component. That is, it can also be mounted on other vehicles, construction machinery, and even residential buildings. Additionally, the resin molded article is not limited to those that allow light to pass through. For example, it can also be used as a cover for an airbag device. The present invention is not limited to the embodiments provided, as long as the effects and benefits of the invention are achieved.
