Description

[Technical field]

[0001] The present invention relates to an instrument device such as a meter installed in a vehicle or the like. [Background technology]

[0002] Instrument devices such as meters installed in vehicles, etc., may be provided with design parts for decoration, etc. For example, Patent Document 1 describes that a decorative frame, which is a ring-shaped frame made of, for example, colorless and transparent acrylic resin, is provided in contact with the front surface of the dial, and a cover is placed on the covering portion of the decorative frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-128883 A Summary of the Invention [Problem to be solved by the invention]

[0004] The decorative frame (design part) described in Patent Document 1 is transparent. However, if the decorative frame is molded in a color that easily reflects light, such as silver or white, the molded color, such as silver, may be visible to the driver or other persons in the gap formed between the endpaper and the decorative frame.

[0005] If you want to express this gap in a dark color in the design, the molding color of the decorative part will be visible, which goes against the design intent. Therefore, for example, it is possible to make the gap a dark color by using mask painting or two-color molding, but this will increase costs.

[0006] In view of the above problems, an object of the present invention is to provide an instrument device that can realize an expression that is in line with design intent at low cost. [Means for solving the problem]

[0007] The invention made to solve the above problem is an instrument device comprising a case, a frame-shaped decorative part provided on the case, and another part at least partially overlapping the decorative part, wherein a groove is formed in at least a part of the boundary where the other part is positioned of the decorative part, and the bottom of the groove is inclined. Effect of the Invention

[0008] According to the present invention, a groove is formed at the boundary with another part, and the bottom of the groove is sloped, so that the light incident on the groove is not reflected along the same path. Therefore, the molded color of the design part is less noticeable, and it is possible to realize an expression that conforms to the design intention at low cost. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of an instrument device according to an embodiment of the present invention. In the following description, for convenience, the direction along the long side of a rectangle that is the shape of a case or the like is defined as the left-right direction, and the direction along the short side of the rectangle is defined as the up-down direction. The left-right direction corresponds to the width direction of a vehicle when the instrument device is installed in the vehicle. The up-down direction corresponds to the height direction of the vehicle when the instrument device is installed in the vehicle.

[0011] The instrument device 1 shown in Fig. 1 is mounted, for example, on an instrument panel in front of the driver's seat of a vehicle. The instrument device 1 includes a case 2, a dial 3, a bezel 4, and a face cover 5. As shown in Fig. 1, the instrument device 1 is assembled by stacking the case 2, the dial 3, the bezel 4, and the face cover 5 in this order.

[0012] Case 2 is a one-piece resin molded product having a substantially rectangular outer shape. Case 2 is formed with recesses and the like capable of accommodating electronic components and the like mounted on a substrate (not shown). On the substrate, for example, a driving motor for the indicating instrument, light-emitting elements for warning displays on dial 3, and driving circuits for driving them are mounted.

[0013] The dial 3 is a member consisting of a substantially rectangular plate body, and is a member on which various designs such as scales, patterns, symbols, characters, decorations, etc. are drawn according to information related to the vehicle on which the instrument device 1 is mounted. For example, a speedometer dial design, a tachometer dial design, etc. are drawn on the dial 3 by a well-known method such as printing.

[0014] As shown in Fig. 2, the bezel 4 is a design component formed in a substantially rectangular frame shape. Fig. 2 is a front view of the bezel 4 alone. The bezel 4 is disposed along the edge of the dial 3. The bezel 4 is composed of a frame portion 41 formed in an annular flat plate, a protrusion 42 formed on part of the inner circumference of the frame portion 41, and a groove portion 43 formed between the protrusion 42 and the frame portion 41.

[0015] As shown in FIG. 2, holes 411 to 417 are provided in the frame portion 41 of the bezel 4. Hole 411 is provided in approximately the center of the upper side of the frame portion 41. Hole 412 is provided in approximately the right end of the upper side of the frame portion 41. Hole 413 is provided in approximately the center of the right side of the frame portion 41. Hole 414 is provided in approximately the right end of the lower side of the frame portion 41. Hole 415 is provided in approximately the left end of the lower side of the frame portion 41. Hole 416 is provided in approximately the center of the left side of the frame portion 41. Hole 417 is provided in approximately the left end of the upper side of the frame portion 41.

[0016] A pin (not shown) provided on the case 2 enters into the holes 411 to 417, thereby positioning the bezel 4 with respect to the case 2. The pin is formed in a substantially cylindrical shape and is provided so as to protrude from the case 2.

[0017] The inside cover 5 is a frame-shaped surrounding member that surrounds the periphery of the dial 3 and the bezel 4 to hold the dial 3, the bezel 4, etc. The inside cover 5 is provided on the frame portion 41 so as to fit along the protruding portion 42 of the bezel 4. In other words, the inside cover 5 is another part that is layered on the bezel 4.

[0018] Next, the relationship between the bezel 4 and the end cover 5 will be described with reference to Figures 3 and 4. Figures 3 and 4 are cross-sectional views taken along line AA in Figure 1. In this embodiment, the bezel 4 is molded in silver, and the end cover 5 is molded in black. In terms of the design of the instrument 1, it is intended that the gap formed between the bezel 4 and the end cover 5, i.e., the groove 43, be visible in black or a dark color similar to black.

[0019] In this embodiment, the gap formed between the convex portion 42 of the bezel 4 and the endpaper 5 is a groove 43. That is, the boundary portion where the endpaper 5 of the bezel 4 is positioned is the groove 43. The bottom portion 43a of this groove 43 is formed in a slope shape along the width direction of the groove 43. Therefore, as shown in FIG. 4, the external light L incident on the groove 43 is reflected by the bottom portion 43a toward the side wall of the groove 43, so that the molding color of the bezel 4 in the gap portion with the endpaper 5 is difficult to see for the driver's eye e.

[0020] Here, it is preferable that the groove 43 is as deep as possible while still ensuring the strength of the bezel 4. If the groove 43 is deep, reflected light is less likely to reach the eye e. Also, it is preferable that the groove 43 has a width similar to the gap caused by the assembly tolerance between the bezel 4 and the endpaper 5. In other words, by turning the gap into the groove 43, the gap can be made to look dark.

[0021] In the example shown in Figures 3 and 4, the slope of the bottom 43a is formed so that the groove 43 becomes shallower from the end 43a1 (see Figure 4) close to the end paper 5 toward the end 43a2 far from the end paper 5, but the groove 43 may be formed so that it becomes deeper from the end 43a1 close to the end paper 5 toward the end 43a2 far from the end paper 5. In other words, the inclination of the slope may be reversed. Figures 5 and 6 show an example in which the end close to the end paper 5 is formed so that it is deeper.

[0022] 5 and 6, the slope of the bottom 43a of the groove 43 is formed so as to become deeper from the end 43a1 close to the end cover 5 toward the end 43a2 far from the end cover 5. Therefore, the external light L incident on the groove 43 is reflected by the bottom 43a toward the side wall of the groove 43 on the convex portion 42 side, making it difficult for the driver's eye e to see the molding color of the bezel 4 in the gap with the end cover 5.

[0023] According to this embodiment, the instrument device 1 includes a case 2, a frame-shaped bezel 4 provided on the case 2, and an endpaper 5 provided on the front surface of the bezel 4. The bezel 4 and the endpaper 5 are molded in different colors, and a groove 43 is formed along a protruding portion 42 that is at least a part of the boundary portion where the endpaper 5 of the bezel 4 is positioned, and a bottom portion 43a of the groove 43 is inclined.

[0024] By configuring the instrument device 1 as described above, the external light L incident on the groove 43 is not reflected along the same path as the incident light. Therefore, the molding color of the bezel 4 is difficult to see. Therefore, mask painting, two-color molding, etc. are not required, and it is possible to realize an expression that conforms to the design intention at low cost.

[0025] The slope of the bottom 43a may be formed so that the end 43a1 closer to the end cover 5 is shallower, or may be formed so that the end 43a1 closer to the end cover 5 is deeper. By doing so, the external light L entering the groove 43 is reflected toward the side wall of the groove 43, making it difficult for the driver and the like to see the molding color in the groove 43.

[0026] It is more effective to use different molding colors for the bezel 4 and the endpaper 5 as in the embodiment described above, but the present invention can be applied regardless of the molding color if the boundary between the decorative part and other parts is to be expressed darkly for design purposes.

[0027] In addition, in the above-described embodiment, the grooves 43 are formed in the area where the convex portion 42 of the bezel 4 is located, but the grooves 43 may be formed only in the areas that are likely to be visible to the driver or the like.

[0028] Furthermore, the present invention is not limited to the above-described embodiment. In other words, a person skilled in the art can implement the present invention by modifying it in various ways in accordance with conventional knowledge without departing from the gist of the present invention. As long as the instrument device of the present invention is still provided even after such modification, it is of course included in the scope of the present invention. [Explanation of symbols]
