Effect of the Invention

[0008] According to the present invention, the dial is fixed by inserting a convex portion into an opening formed in a double-supported beam shape, thereby increasing the strength of the fixing portion and making it less susceptible to damage, thereby improving the strength when assembling the dial. [Brief description of the drawings]

[0009] [Figure 1] 1 is a perspective view of an instrument device according to an embodiment of the present invention; [Diagram 2] FIG. 2 is an enlarged view of the fixing portion shown in FIG. [Diagram 3] 2 is an enlarged view of a state in which the fixing portion is fixed by the protrusion shown in FIG. 1. 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] 1 is provided, for example, on an instrument panel in front of the driver's seat of a vehicle. The instrument device 1 includes a case 2 and a dial 3. In addition to the case 2 and the dial 3, a bezel (design component), a faceplate, etc. may also be provided.

[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 pointer of the indicating instrument, light-emitting elements for warning displays on dial 3, and driving circuits for driving them are mounted.

[0013] The case 2 is formed with fixing parts 21 and 22 for preventing the dial 3 from floating up. The fixing parts 21 and 22 are provided, for example, on the periphery of a hole through which the rotating shaft of the hand passes. In other words, the fixing parts 21 and 22 are provided at an interval along the longitudinal direction of the case 2.

[0014] 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 in which the instrument device 1 is mounted. For example, a speedometer dial design, a rotary system dial design, etc. are drawn on the dial 3 by a well-known method such as printing.

[0015] The dial 3 has holes 31, 32 formed at positions corresponding to the fixing portions 21, 22. The holes 31, 32 have protrusions 311, 321 formed therein for fixing the dial to the case 2. The protrusions 311, 321 will be described later with reference to FIG.

[0016] 2 shows an enlarged view of fixed portion 21. Fixed portion 22 has a similar configuration. Fixed portion 21 is formed on the periphery of hole 214 through which the rotary shaft of the pointer passes. Fixed portion 21 has a double-supported beam portion 211. Double-supported beam portion 211 is made up of erected portions 211a, 211b and beam portion (beam portion) 211c. Double-supported beam portion 211 is formed into an arch shape (approximately U-shaped) by erected portions 211a, 211b and beam portion 211c.

[0017] The erected portions 211a, 211b stand upright from the periphery of the hole 214. The base portion (joint portion) 212 of the erected portions 211a, 211b is R-shaped (curved surface). In other words, the base portions of the erected portions 211a, 211b are not perpendicular to the flat portion of the case 2, but are formed so as to gradually rise upright via a curved surface. That is, the joint portions of the fixing portion 21 with the case 2 at both ends have curved surfaces.

[0018] Both ends of beam portion 211c are supported by erected portions 211a and 211b. Beam portion 211c is formed in a curved prism shape along the arc formed by hole 214, but the corners are chamfered. Beam portion 211c also has a lower surface 211c1 into which protrusion 311 is inserted that is chamfered.

[0019] Hole 214 is generally circular, but extends to the portion between erected portions 211a and 211b, so that the hole is enlarged as if a portion of a circle were protruding. Therefore, the portion surrounded by the expanded portion of hole 214 and erected portions 211a, 211b, and beam portion 211c of doubly supported beam portion 211 functions as opening 213 into which protrusion 311 is inserted.

[0020] Fig. 3 shows the dial 3 in a fixed state. That is, it shows the state where the convex portion 311 is inserted into the fixing portion 21 (opening 213) and fixed. Note that Fig. 3 shows the fixing portion 21 and the convex portion 311, but the fixing portion 22 and the convex portion 321 are similar.

[0021] As described above, the dial 3 is formed with the hole 31. The hole 31 is shaped like an elongated hole so that the rotating shaft of the pointer passing through the hole 214 and the double-supported beam portion 211 can pass therethrough.

[0022] A protrusion 311 is formed at one end of the elongated hole shape. The protrusion 311 protrudes in a generally rectangular shape that protrudes toward the inside of the hole 31 (the center of the hole). The protrusion 311 is inserted into the opening 213 of the fixing part 21. When the protrusion 311 is inserted into the insertion opening, it is pressed and locked by the beam part 211c, preventing the dial 3 from floating up.

[0023] The dial 3 is attached to the case 2 by inserting the convex portion 311 into the fixed portion 21 (opening 213) from the bottom side in FIG. 3, and similarly inserting the convex portion 321 into the fixed portion 22. The dial 3 is then provided so as to be covered and hidden by the case 2. At this time, a positioning hole or the like may be provided for the dial 3, and positioning may be performed by inserting a pin provided on the case 2 into the hole. In this manner, the dial 3 is attached to the case 2.

[0024] According to this embodiment, the instrument device 1 includes a case 2 and a dial 3 attached to the case 2. A hole 31 is formed in the dial 3, and a protrusion 311 that protrudes toward the inside of the hole 31 is formed in the hole 31, and a fixing portion 21 in the form of a double-supported beam is formed at a position of the case 2 corresponding to the hole 31, which engages the protrusion 311 to fix the dial 3 to the case 2.

[0025] By configuring the instrument device 1 as described above, the dial 3 is fixed by inserting the convex portion 311 into the opening 213 formed by the double-supported beam portion 211 of the fixing portion 21. This increases the strength of the fixing portion 21 and makes the dial 3 less likely to break even if the thickness of the dial 3 increases, thereby improving the strength when assembling the dial 3.

[0026] Furthermore, since beam portion 211c of double-supported beam portion 211 is chamfered, convex portion 311 can be smoothly inserted into the opening without getting caught.

[0027] Furthermore, in the doubly supported beam portion 211, the joint portion 212 between the standing portions 211a and 211b and the case 2 has a curved surface (R-shape), so that the strength of the standing portions 211a and 211b can be improved.

[0028] In addition, holes 214 and 31 are provided to correspond to the rotation axis of the pointer that rotates along the surface of dial 3, so the hole through which the rotation axis passes can also serve the function of fixing dial 3. Therefore, there is no need to provide a separate fixing part.

[0029] 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]
