Abstract
Description
[Technical field]
[0001] The present invention relates to a resin molded product that is fixed to a plate-like member formed into a plate shape when in use. [Background technology]
[0002] For example, in a vehicle equipped with a head-up display device, a resin molded product may be fixed to an instrument panel serving as a plate-like member. The resin molded product is disposed above the head-up display device and covers a part of an opening formed in the instrument panel.
[0003] Various resin molded products are known that are used by being fixed to a plate-like member, not limited to covers for head-up display devices. A conventional technique related to such resin molded products is disclosed in Patent Document 1. The resin molded product disclosed in Patent Document 1 will be described with reference to FIG. 7A of the present application.
[0004] 7A shows the resin molded product shown in Patent Document 1 again. Resin molded product 120 as a lid for an airbag device is fixed to an instrument panel as a plate-like member 111 when in use. A front edge portion 140, which is the front edge of resin molded product 120, is formed in a substantially U-shape that opens forward. Resin molded product 120 is fixed to plate-like member 111 such that end portion 111c of plate-like member 111 is sandwiched between front edge portion 140 formed in a substantially U-shape. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] JP 2000-177523 A Summary of the Invention [Problem to be solved by the invention]
[0006] Incidentally, in order to enable the resin molded product 120 to be fixed at an appropriate position relative to the plate-like member 111, the position and size of the front edge portion 140 of the resin molded product 120 are adjusted at the design stage.
[0007] Please refer to FIG. 7B. FIG. 7B is a diagram for explaining a method for adjusting the front edge portion. When designing the resin molded product 120, a production mold for the resin molded product 120 is first manufactured so that the front edge portion 140 is formed smaller than expected. Then, the relevant portion of the production mold is gradually cut so that the front edge portion 140 can be placed in an appropriate position relative to the plate-like member 111. By cutting the production mold, the shape of the front edge portion 140 changes by the amount cut. As a result, the portion where the front edge portion 140 abuts against the plate-like member 111 changes, and adjustment is repeated until the resin molded product 120 is fixed in the appropriate position.
[0008] At this time, the lower surface 141 of the front edge portion 140 is inclined with respect to the end portion 111c of the plate-shaped member 111. When the lower surface 141 of the front edge portion 140 is adjusted to be raised, the position of the resin molded product 120 changes with respect to the plate-shaped member 111 in both the direction along the surface of the plate-shaped member 111 and the direction perpendicular to the surface. Even if the mounting position of the resin molded product 120 is optimal in the direction along the surface of the plate-shaped member 111, it may not be optimal in the direction perpendicular to the surface. It is desired that the resin molded product 120 can be fixed at an optimal position with respect to the plate-shaped member 111.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] An embodiment of the present invention will be described below with reference to the attached drawings. In the description, left and right refer to the left and right with respect to the occupant of the vehicle in which the resin molded product is mounted, and front and rear refer to the front and rear with respect to the traveling direction of the vehicle. In the drawings, Fr indicates the front, Rr indicates the rear, Le indicates the left as seen by the occupant, Ri indicates the right as seen by the occupant, Up indicates the top, and Dn indicates the bottom.
[0020] <Example> The embodiment will be described with reference to the drawings.
[0021] Please refer to Fig. 1. A resin molded product 20 is mounted on, for example, a vehicle 10. More specifically, the resin molded product 20 is used by being fixed to an instrument panel 11 provided at the front part of the vehicle interior. A head-up display device 12 capable of emitting light is provided below the resin molded product 20.
[0022] The instrument panel 11 is a resin member formed into a plate shape, and can also be called the plate-shaped member 11. The plate-shaped member 11 may be any plate-shaped member capable of fixing the resin molded product 20. For this reason, the material of the plate-shaped member may be any material such as metal in addition to resin.
[0023] The light emitted from the head-up display device 12 is projected, for example, onto the windshield. The occupant can obtain information such as the vehicle speed by visually checking the light projected onto the windshield. The light emitted from the head-up display device 12 may be projected onto a projection unit called a combiner.
[0024] 2 and 3, the resin molded product 20 is formed by injection molding. The resin molded product 20 is fixed to the edge of a plate-shaped member opening 11a formed in the plate-shaped member 11.
[0025] The resin molded product 20 has a main body 30 formed in an approximately rectangular frame shape, a contact support portion 23 protruding from the front of the main body 30 along the plate-shaped member 11, and a rear engagement portion 24 formed at the rear of the main body 30 and hooked onto the edge of the plate-shaped member opening 11a.
[0026] 4, the resin molded product 20 further has an upper surface abutting portion 26 that extends from the main body portion 30 to the upper surface 11b of the plate-like member 11 and can abut against the upper surface 11b of the plate-like member 11, an end surface abutting portion 27 that protrudes upward from the rear of the abutment portion support portion 23 and can abut against the end surface 11c of the plate-like member opening 11a, and a lower surface abutting portion 28 that protrudes upward from the front end of the abutment portion support portion 23 and can abut against the lower surface 11d of the plate-like member opening 11a.
[0027] Also refer to Figure 3. The main body 30, the contact support portion 23, the rear locking portion 24, the upper surface contact portion 26, the end surface contact portion 27, and the lower surface contact portion 28 are integrally formed.
[0028] Referring to Fig. 2, the main body 30 is formed by connecting four peripheral walls 31 to 34 in a substantially rectangular shape. The peripheral walls 31 to 34 consist of a front wall 31 formed at the front and extending vertically, a left wall 32 extending rearward from the left end of the front wall 31, a right wall 33 extending rearward from the right end of the front wall 31, and a rear wall 34 extending left and right to connect the rear ends of the left wall 32 and the right wall 33.
[0029] The lower ends of the peripheral walls 31 to 34 are formed as an opening 35 through which light emitted from below can pass. The upper ends of the peripheral walls 31 to 34 are formed as an upper surface portion 36 formed in a frame shape.
[0030] The front wall 31 has a rectangular shape that is long in the left-right direction. The left wall 32 and the right wall 33 have a trapezoid shape with upper and lower sides that are approximately parallel. The rear sides of the left wall 32 and the right wall 33 are inclined so that their lower ends are located further forward than their upper ends. The rear wall 34 has a substantially rectangular shape in a plan view. The rear wall 34 is formed with a downward slope toward the front, and curves upward from the center in the front-to-rear direction to the rear.
[0031] Please refer to Fig. 2. Three abutment support parts 23 are formed discontinuously in the left-right direction of the main body part 30. Please refer to Fig. 4. A portion of the abutment support part 23 is connected to the rear surface of the main body part 30. A gap Sp is formed between the abutment support part 23 and the upper surface abutment part 26. A portion of the abutment support part 23 is located below the upper surface abutment part 26.
[0032] 5, the contact portion support portion 23 has a support portion main body 23a that protrudes forward from the main body portion 30, and a side wall portion 23b that rises from the main body portion 30 and closes one side surface of the support portion main body 23a.
[0033] Referring to Fig. 3, the rear engaging portion 24 includes a rear first contact portion 24a that extends along the upper surface 11b of the plate-shaped member 11 and contacts the upper surface 11b of the plate-shaped member 11, and a rear second contact portion 24b that contacts the end surface 11c of the plate-shaped member opening 11a.
[0034] The rear first contact portion 24a is formed to be inclined with respect to the upper surface portion 36. As a result, the end face of the rear first contact portion 24a abuts against the upper surface 11b of the plate-like member 11 and is not visible from the outside.
[0035] Please refer to Fig. 4. The upper surface abutment portion 26 connects the main body portion 30 to the upper surface 11b of the plate-like member 11, and is inclined with respect to both the main body portion 30 and the upper surface 11b of the plate-like member 11. The end face of the upper surface abutment portion 26 abuts against the upper surface 11b of the plate-like member 11, and is not visible from the outside.
[0036] The top surface contact portion 26 has a thin-walled tip, and this thin-walled portion contacts the top surface 11b of the plate-like member 11.
[0037] The end surface 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 surface abutment portion 27 includes an end surface abutment surface 27a that can abut against the end surface 11c of the plate-shaped member 11. The end surface abutment surface 27a is formed along the end surface 11c of the plate-shaped member 11. In other words, the end surface abutment surface 27a is disposed facing substantially the same direction as the end surface 11c of the plate-shaped member 11. It is preferable that the end surface abutment surface 27a is in line contact or surface contact with the end surface 11c of the plate-shaped member 11.
[0038] The end surface abutment portion 27 is formed at a position overlapping the side wall portion 23b of the abutment portion support portion 23. The end surface abutment portion 27 is formed flush with the side wall portion 23b.
[0039] The position of the end abutment surface 27a can be adjusted by cutting the molding die. By cutting 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 product 20 in the front-rear direction can be adjusted.
[0040] The lower surface abutment portion 28 is formed outside the area covered by the upper surface abutment portion 26, and is spaced apart from the end surface abutment portion 27. The lower surface abutment portion 28 includes a lower abutment surface 28a that can abut against the lower surface 11d of the plate-like member 11. The lower abutment surface 28a is formed on a surface that is approximately perpendicular to the end surface abutment surface 27a. The lower abutment surface 28a is formed at the highest position of the lower surface abutment portion 28.
[0041] The lower surface abutment portion 28 is formed at a position overlapping the side wall portion 23b of the abutment portion support portion 23. The lower surface abutment portion 28 is formed flush with the side wall portion 23b.
[0042] The position of the lower abutment surface 28a can be adjusted by cutting the molding die. By cutting 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 product 20 can be adjusted.
[0043] The end surface abutment portion 27 and the lower surface abutment portion 28 may be protruded directly from the main body portion 30 without using the abutment portion support portion 23 therebetween.
[0044] A method for attaching the above-described resin molded product 20 to the plate-like member 11 will now be described.
[0045] Please refer to Figures 6A and 6B. First, as shown by arrow 41, the gap Sp between the upper surface abutment portion 26 and the abutment portion support portion 23 is made to face the end surface 11c of the plate-shaped member 11. After the gap Sp is made to face, the resin molded product 20 is rotated while sliding forward as shown by arrows 42 and 43, so that the upper surface abutment portion 26 is brought into abutment with the upper surface 11b of the plate-shaped member 11, and the end abutment surface 27a is slid forward until it abuts against the end surface 11c of the plate-shaped member 11. At this time, the rear locking portion 24 (see Figure 3) is pressed downward, so that the rear of the resin molded product 20 is fixed, and the lower surface abutment portion 28 abuts against the lower surface 11d of the plate-shaped member 11. By bringing the upper surface abutment portion 26, the end surface abutment portion 27, and the lower surface abutment portion 28 into contact with the plate-like member 11, the resin molded product 20 can be fixed at an accurate position on the plate-like member 11.
[0046] The above-described resin molded product 20 will now be summarized.
[0047] Please refer to Fig. 4. The resin molded product 20 is used by being fixed to a plate-like member 11 formed into a plate shape. Moreover, the resin molded product 20 has a main body 30 integrally formed with an upper surface abutting portion 26 capable of abutting against an upper surface 11b of the plate-like member 11, an end surface abutting portion 27 capable of abutting against an end surface 11c of the plate-like member 11, and a lower surface abutting portion 28 formed separately from the end surface abutting portion 27 and capable of abutting against a lower surface 11d of the plate-like member 11.
[0048] The resin molded product 20 has an end surface abutting portion 27 capable of abutting against the end surface 11c of the plate-like member 11, and a bottom surface abutting portion 28 formed separately from the end surface abutting portion 27 and capable of abutting against the bottom surface 11d of the plate-like member 11. The end surface abutting portion 27 that abuts against the end surface 11c of the plate-like member 11 and the bottom surface abutting portion 28 that abuts against the bottom surface 11d are separate. This makes it possible to fix the resin molded product 20 at optimal positions relative to the end surface 11c and the bottom surface 11d of the plate-like member 11. In other words, it is possible to provide a resin molded product 20 that can be fixed at a desired position relative to the plate-like member 11.
[0049] Of the end face abutment portion 27, an end face abutment surface 27a capable of abutting against the end face 11c of the plate-like member 11 is disposed facing substantially the same direction as the end face 11c of the plate-like member 11. A wide abutment surface can be secured, and the resin molded product 20 can be reliably fixed at a desired position.
[0050] The lower contact surface 28a of the lower contact portion 28, which can contact the lower surface 11d of the plate-like member 11, is formed on a surface that is approximately perpendicular to the end contact surface 27a. This allows the lower contact surface 28a and the lower surface 11d of the plate-like member 11 to also come into line contact with each other. This makes it possible to more reliably fix the resin molded product 20 at the desired position.
[0051] The end surface abutment portion 27 is formed at a position covered by the upper surface abutment portion 26. The lower surface abutment portion 28 is formed outside the area covered by the upper surface abutment portion 26. By forming the end surface abutment portion 27 at a position covered by the upper surface abutment portion, the end surface abutment portion 27 is not exposed to the outside, and the appearance of the resin molded product 20 can be improved. By forming the lower surface abutment portion 28 outside the area covered by the upper surface abutment portion 26, a large gap Sp can be secured, and the work of attaching the resin molded product 20 to the plate-like member 11 can be facilitated. Note that the lower surface abutment portion 28 is a portion that abuts against the lower surface 11d of the plate-like member 11, and is covered by the plate-like member 11, so that the appearance is not deteriorated even if it is formed outside the area covered by the upper surface abutment portion 26.
[0052] It further has a contact portion support portion 23 that protrudes from the main body portion 30 along the plate-like member 11. In addition, the end face abutment portion 27 and the lower face abutment portion 28 are formed on the outer surface of the abutment portion support portion 23. By forming the abutment portion support portion 23, it is possible to increase the support rigidity of the end face abutment portion 27 and the lower face abutment portion 28, and it is only necessary to form the end face abutment portion 27 and the lower face abutment portion 28 small. Because the end face abutment portion 27 and the lower face abutment portion 28 are small, adjustment work is also facilitated, and the manufacturing cost of the resin molded product 20 can be reduced.
[0053] The upper surface abutment portion 26 connects the main body portion 30 to the upper surface 11b of the plate-like member 11, and is inclined with respect to the main body portion 30. The end portion of the upper surface abutment portion 26 can be made invisible from the outside, which improves the appearance of the resin molded product 20 while also improving the degree of freedom in design.
[0054] Please refer to FIG. 3. The main body 30 has an opening 35 through which light emitted from below can pass. The opening 35 is surrounded by peripheral walls 31-34 extending in the vertical direction. When transmitting the emitted light, it is particularly desirable to place the resin molded product 20 in an accurate position relative to the device that emits the light (e.g., the head-up display device 12). The resin molded product 20 can be fixed to a desired position relative to the plate-like member 11, and is particularly preferable as a resin molded product that transmits the emitted light.
[0055] 4, the end surface abutment portion 27 and the lower surface abutment portion 28 are formed flush with the side wall portion 23b. This makes it easy to adjust the shapes of the end surface abutment portion 27 and the lower surface abutment portion 28.
[0056] The location where the resin molded product is mounted is not limited to the inside of a vehicle cabin, as long as it is fixed to a plate-like member. In other words, it can be mounted on vehicles other than vehicles and construction machines. It can also be used in houses and the like. Furthermore, the resin molded product is not limited to those that can transmit light. For example, it can be used as a cover for an airbag device. As long as the action and effect of the present invention are achieved, the present invention is not limited to the embodiments. [Industrial Applicability]
