  In the conventional instrument described above, the width dimension of the locking hole provided in the dial plate is such that the locking piece needs to be elastically deformed so that the claw at the tip can easily pass through the locking hole. The length of the projecting direction of the part is set large.

  For this reason, since the locking piece of the ring member can move within the locking hole as the width dimension of the locking hole is large, there is a difficulty in the position holding force of the ring member, and the dial plate of the ring member There is a problem that the positional accuracy in the above is lowered.

  The present invention has been made in view of the above points, and an object of the present invention is to increase the position holding force of a frame-like member such as a ring member and to improve the mounting position accuracy of the frame-like member. It is.

  The present invention employs the following technical means to achieve the above object.

  The instrument according to claim 1 of the present invention is an instrument including a display body for displaying a display design, and is formed at a frame-shaped member arranged on the viewing side of the display body and an end of the frame-shaped member. The fixing member includes an opening hole provided in the display body and fixing the frame-shaped member via the fixing member. The fixing member includes a guide portion that contacts one side of the opening hole, and the other side that faces one side of the opening hole. The frame-shaped member is fixed to the display body by fitting the guide part and the stopper part of the fixing member into the opening hole. It is characterized by that.

  According to such a configuration, in a state where the frame-shaped member is mounted on the display body, the fixing member is in contact with two opposite sides of the opening hole of the display body via the stopper portion and the guide portion. The fixing member is restricted from moving in the opening hole.

  Thereby, the position holding force to the opening hole of the fixing member of the frame-shaped member can be increased, and the accuracy of the attachment position of the frame-shaped member to the display body can be increased.

  In the instrument according to claim 2 of the present invention, a frame-like member is fixed to the turning member disposed on the viewing side of the display body instead of the display body of claim 1 with the same configuration as in claim 1. It is characterized by this.

  In the meter according to claim 3 of the present invention, at least one of the guide portion and the stopper portion of the fixing member can be deformed so as to approach the other when assembled to the opening hole of the frame-like member. is there.

  As a result, when the fixing member is inserted into the opening hole, the force exerted on the opening hole by the fixing member is reduced to prevent the display body or the turning member from being damaged, and the pushing force required for the insertion is reduced. Assembly workability can be improved.

  In the instrument according to claim 4 of the present invention, the guide part and the stopper part overlap each other in the deformation direction of at least one of the guide part and the stopper part when the frame-like member is assembled to the opening hole. It is set as the structure arranged without.

  Thereby, similarly to the case of claim 3, it is possible to reduce the width of the opening hole while making it possible to prevent damage to the turn-back member and to improve the assembling workability at the time of assembling the frame-shaped member to the opening hole. .

  Hereinafter, the case where the meter according to the present invention is applied to a fuel meter 1 mounted on a combination meter 100 installed in a passenger compartment of an automobile will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a partial front view of a combination meter 100 including a fuel gauge 1 according to the first embodiment of the present invention. In FIG. 1, the upper side is the upper side of the automobile, and the left-right direction is the width direction of the automobile.

  FIG. 2 is a cross-sectional view of the fuel gauge 1 according to the first embodiment of the present invention, and is a cross-sectional view taken along the line II-II in FIG. In FIG. 2, the left side is a driver's seat, and the fuel gauge 1 is visually recognized from the left side in FIG.

  FIG. 3 is an enlarged cross-sectional view of the fuel gauge 1 according to the first embodiment of the present invention, and is a cross-sectional view taken along line III-III in FIG.

  4 is an enlarged sectional view of the fuel gauge 1 according to the first embodiment of the present invention, and is a sectional view taken along line IV-IV in FIG.

  FIG. 5 is a schematic diagram for explaining an electric circuit configuration of the combination meter 100 including the fuel gauge 1 according to the first embodiment of the present invention.

  The combination meter 100 is provided in front of the driver's seat in the passenger compartment of the automobile so that the driver can visually recognize the information on the operating state of the automobile (residual fuel amount, travel speed, engine speed, etc.) and other various information. It is displayed by a pointer instrument.

  As shown in FIG. 1, the fuel gauge 1 that is an instrument is roughly a dial 2 that is a display body having scales and numbers as a display design, and a pointer 5 that rotates along the surface of the dial 2. The remaining fuel amount in the fuel tank (not shown) of the automobile is instructed to be visible to the driver by the turning angle of the pointer 5.

  The dial plate 2 which is a display body is formed of a light-transmitting material, for example, a thin plate such as colorless and transparent polycarbonate resin or acrylic resin, and is visible to the driver so as to be visible to the driver (not shown, left side of FIG. 2). Are arranged opposite to each other. The dial 2 includes a scale 21, a character 22 and a figure 23 as a display design. These scales 21 and characters 22 are for indicating the amount of remaining fuel in a fuel tank (not shown) of the automobile together with a pointer 5 described later. Further, the graphic 23 indicates that this meter is a meter that indicates the remaining fuel amount, and its shape is determined by Japanese Industrial Standards. The scale 21, the character 22 and the graphic 23 are formed by applying a light-shielding film on the surface 25 of the dial plate 2 except for the scale 21, the character 22 and the graphic 23 by printing or the like. That is, only the scale 21, the characters 22, and the graphic 23 are translucent, and their surroundings are light-shielding. Thereby, the scale 21, the character 22 and the figure 23 are transmitted and illuminated by light from a light emitting diode 4 which will be described later as a light source which is disposed on the back side (right side in FIG. 2) of the dial 2 and transmits the dial 2 through the dial. Is displayed.

  Further, as shown in FIG. 2, the dial 2 is provided with a through-hole 24 through which a shaft 61 that is a rotation shaft of a movement 6 as a driving device described later is inserted.

  Further, as shown in FIG. 2, the dial 2 is provided with a through hole 26 as an opening hole for locking and fixing a decorative ring 8 as a frame-like member described later. In the fuel gauge 1 according to the first embodiment of the present invention, the through hole 26 is formed in a rectangular shape in plan view as shown in FIG. Further, in the fuel gauge 1 according to the first embodiment of the present invention, three through holes 26 are provided at equiangular intervals as shown in FIG.

  In the fuel gauge 1 according to the first embodiment of the present invention, the scale 21, the character 22 and the figure 23 are provided with a translucent white paint, and a light-shielding black paint is provided around them. However, it is not necessary to limit to the combination as described above, and the scale 21, the character 22 and the figure 23 may be colorless and transparent. In this case, the scale 21, the characters 22, and the graphic 23 are displayed by light emission in the light emission color of the light emitting diode 4.

  On the back side (right side in FIG. 2) of the dial plate 2 is disposed a light guide 3 that guides light from the light emitting diode 4 to a scale 21, a character 22, and a graphic 23 that are display designs. The light guide 3 is made of a translucent material such as a colorless and transparent polycarbonate resin or acrylic resin. As shown in FIG. 2, the light guide 3 includes a light receiving portion 32 that introduces light emitted from the light emitting diode 4 into the light guide 3, a light introduced from the light receiving portion 32, a scale 21 on the dial 2, a character 22 and the reflection part 31 which reflects toward the figure 23 are provided.

  As shown in FIG. 2, a light emitting diode 4 as a light source is disposed behind the dial 2, that is, behind the light guide 3 so that light can enter the light receiving portion 32.

  The pointer 5 is made of a translucent material such as a colorless and transparent polycarbonate resin or acrylic resin, and is disposed along the viewing side of the dial 2, that is, along the surface 25 as shown in FIG. The pointer 5 is fixed to a shaft 61 that is a rotation shaft of a movement 6 that is a driving device to be described later disposed on the back side (right side in FIG. 2) of the dial 2. As a result, when the movement 6 is driven and the shaft 61 rotates, the pointer 5 rotates integrally with the shaft 61. The back surface 51 of the pointer 5 is colored red by printing or hot stamping. As a result, the pointer 5 is illuminated by light from the light emitting diode 7 which is a white light emitting diode whose light emission color is a white light emitting diode as a light source for illuminating the pointer 5 disposed on the back side (right side of FIG. 2) of the dial 2. Is displayed in red. That is, the light emitted from the light emitting diode 7 incident on the pointer 5 is reflected by the reflecting surface 52 of the pointer 5 toward the tip of the pointer 5, and this reflected light is reflected by the back surface 51 in the driver's visual recognition direction. Is done. That is, in the fuel gauge 1 according to the first embodiment of the present invention, by using a white light emitting diode as the light emitting diode 7, the pointer 5 is lit and displayed in the color of the colored layer applied to the back surface 51 of the pointer 5. . In this case, the color of the colored layer applied to the back surface 51 of the pointer 5 does not need to be limited to red, and may be colored to other colors, for example, orange or green. On the other hand, a white colored layer may be provided on the back surface 51 of the pointer 5, and a light emitting diode having a color other than white may be used as the light emitting diode 7. In this case, the pointer 5 is lit and displayed by the light emission color of the light emitting diode 7.

  Further, a light shielding cap 11 that covers the reflective surface 52 of the pointer 5 and the vicinity thereof is attached to the pointer 5 as shown in FIG. The light shielding cap 11 is made of a light shielding material, for example, a black resin material, and prevents light from the light emitting diode 7 from directly entering the eyes of the viewer and dazzling the viewer. .

  For example, a cross coil actuator or a stepping motor is used as the movement 6 that is a driving device that generates a driving force for rotating the pointer 5. When a voltage is applied from the outside, the movement 6 generates torque and rotates the shaft 61 that is a rotating shaft. As a result, the pointer 5 fixed to the tip of the shaft 61 rotates along the surface 25 of the dial 2.

  The light emitting diode 4, the movement 6 and the light emitting diode 7 described above are mounted on a printed circuit board 9 disposed on the back side (right side in FIG. 2) of the dial 2. The printed board 9 is formed of, for example, a glass epoxy board or the like, and forms an electric circuit portion of the combination meter 100. A cylindrical light shielding cylinder 10 is mounted on the printed circuit board 9 so as to surround the light emitting diode 7 for illumination of the pointer 5. The light-shielding cylinder 10 is formed of a light-shielding member, for example, metal or black resin, and is attached with its both ends in close contact with the back surface of the dial 2 and the printed board 9 as shown in FIG. This prevents light emitted from the light emitting diode 7 from irradiating a portion other than the pointer 5, or prevents light emitted from the light emitting diode 4 from leaking to the outside through the through hole 24 of the dial 2. Further, as shown in FIG. 2, a controller 14 is mounted on the printed circuit board 9 for controlling the turning on / off of the light emitting diode 4 and the light emitting diode 7 and the driving control of the movement 6 for rotating the pointer 5. ing. The controller 14 is composed of, for example, a microcomputer.

  Further, as shown in FIG. 2, a decorative ring 8 that is a frame-like member is attached to the viewing side of the dial 2 (left side in FIG. 2). The decoration ring 8 is formed of, for example, a resin material, and is formed in an annular shape and is disposed concentrically with the shaft 61 as shown in FIG. Thereby, the presence of the fuel gauge 1 in the combination meter 100 is emphasized, and the role of improving the visibility is achieved.

  Further, as shown in FIGS. 2 and 3, the decorative ring 8 is provided with a guide portion 81 and a stopper portion 82 as fixing members for fixing the decorative ring 8 to the dial 2. That is, one guide portion 81 and one stopper portion 82 make a pair and are fitted and locked in one through hole 26 as shown in FIG. In the fuel gauge 1 according to the first embodiment of the present invention, three pairs of guide portions 81 and stopper portions 82 forming a pair are provided corresponding to the through holes 26 of the dial 2.

  As shown in FIG. 3, the guide portion 81 has a straight shape, and the tip end portion (the right end in FIG. 3) is formed smoothly. On the other hand, the stopper portion 82 is formed with a locking portion 82a at the tip portion (the right end portion in FIG. 2). When the decorative ring 8 is attached to the dial 2, the locking portion 82 a is locked to the back surface 27 of the dial 2 to restrict the movement of the decorative ring 8, that is, the leftward movement in FIG. 2. As a result, the decorative ring 8 is prevented from coming off the dial 2.

  Next, assembling structure of the decorative ring 8 to the dial plate 2, which is a feature of the fuel gauge 1 according to the first embodiment of the present invention, that is, the configuration and operational effects of the guide portion 81 and the stopper portion 82 of the decorative ring 8. Will be described.

  First, in the conventional instrument, the width dimension of the opening hole of the dial as a display body is set so that the engaging portion provided at the tip of the fixed member can easily pass through in the process of assembling the frame-like member to the dial. The thickness of the general portion of the fixing member is larger than that of the fixing member.

  For this reason, with the frame-shaped member attached to the dial, a gap is formed between the fixing member and the dial in the width direction of the opening hole, whereby the fixing member moves within the opening hole, in other words, the frame There is a problem that the position holding force of the shaped member to the dial is small.

  On the other hand, in the fuel gauge 1 according to the first embodiment of the present invention, the guide part 81 and the stopper part 82 are inserted into the through hole 26 of the dial 2 when the decorative ring 8 is assembled to the dial 2. When pushed in (from left to right in FIG. 2), the guide portion 81 is in the direction indicated by the arrow in FIG. 3, and the stopper portion 82 is in the direction indicated by the arrow in FIG. 2, in other words, the direction along the surface of the dial 2 They are elastically deformed so as to approach each other (vertical direction in FIG. 2). Further, when the guide portion 81 and the stopper portion 82 are pushed in, the locking portion 82 a of the stopper portion 82 passes through the through hole 26 and is locked to the back surface 27 of the dial 2. At the same time, the guide portion 81 abuts on the side 26a which is one side of the through hole 26 of the dial 2, and the stopper portion 82 abuts on the side 26b which is the other side opposite to the side 26a. Thus, the attachment of the decorative ring 8 to the dial 2 is completed.

  When the attachment of the decorative ring 8 to the dial plate 2 is completed, the guide portion 81 and the stopper portion 82 are in contact with the two opposite sides 26a and 26b of the through-hole 26 of the dial plate 2, so a pair of guides The part 81 and the stopper part 82 are restrained from moving in the through hole 26. That is, the decorative ring 8 is prevented from rotating in the direction indicated by the arrow B in FIG. 4 and moving in the direction indicated by the arrow B in FIG. 4 with the locking portion 82a of the stopper 82 as a fulcrum.

  Thereby, the position holding force of the decoration ring 8 can be increased and the attachment position accuracy of the decoration ring 8 can be increased.

  Further, at the time of assembling the decorative ring 8 to the dial plate 2, at least one of the guide portion 81 and the stopper portion 82 can be deformed so as to approach the other.

  As a result, when the guide portion 81 and the stopper portion 82 are inserted into the through hole 26, the force exerted by the guide portion 81 and the stopper portion 82 on the through hole 26 is reduced to prevent the dial 2 from being damaged. As a result, the push-in force required for insertion can be reduced and the assembly workability can be improved.

  Further, the guide portion 81 and the stopper portion 82 are arranged so as not to overlap each other when viewed from the deformation direction at the time of attaching to the dial plate 2, that is, the vertical direction in FIG. In this case, the width dimension A of the through hole 26 of the dial 2, that is, the dimension in the deformation direction (vertical direction in FIG. 2) of the guide part 81 and the stopper part 9 is the thickness of the guide part 81 as shown in FIG. The sum of the deformation dimension Q of the guide portion 81 and the thickness R of the stopper portion 82 and the attaching operation of the dial plate 2 to the through hole 26 at the time of attaching the thickness dimension P to the through hole 26 of the dial plate 2 This is the sum of the deformation allowance S of the stopper portion 82 at the time.

  As a result, it is possible to reduce the length in the radial direction of the decorative ring 8, which can prevent a part of the through hole 26 from looking into the back of the decorative ring 8, thereby improving the degree of freedom in designing the shape of the decorative ring 8. Is possible.

  The dial plate 2 to which the decorative ring 8 is mounted and the printed circuit board 9 constituting the electric circuit described above are housed and fixed in a casing 13 formed of, for example, a resin material. The casing 13 is extended to the viewing side (left side in FIG. 2) of the dial plate 2, and a transparent cover 12 is installed at the tip of the casing 13 as shown in FIG. The transparent cover 12 is formed of a thin plate such as a transparent resin or glass, and prevents dust and moisture from entering the combination meter 100.

  Next, the electric circuit configuration of the combination meter 100 including the fuel gauge 1 according to the first embodiment of the present invention described above will be described with reference to FIG.

  As shown in FIG. 5, power is constantly supplied from the battery 17 to the controller 14. Further, the controller 14 is connected to the ignition switch 16 so as to be able to detect its operating state (ON or OFF).

  Further, as shown in FIG. 5, a liquid level detection sensor 15 for detecting a fuel level level in a fuel tank mounted on the automobile is connected to the controller 14 so that a detection signal can be input.

  Further, as shown in FIG. 5, the light emitting diode 4, the light emitting diode 7, and the movement 6 are connected to the controller 14.

  The controller 14 detects the operating state of the ignition switch 16, and when the ignition switch 16 is in the ON state, the light emitting diodes 4 and 7 are turned on and the fuel of the vehicle is detected based on the detection signal from the liquid level detection sensor 15. The remaining fuel amount in the tank is calculated, and the movement 6 is driven so that the pointer 5 indicates the calculated remaining fuel amount on the dial 2. On the other hand, when the ignition switch 16 is in the OFF state, the light emitting diodes 4 and 7 are turned off, and the movement 6 is driven so that the pointer 5 indicates the remaining fuel amount 0 on the dial 2, that is, E (Empty). Alternatively, the power supply to the movement 6 is stopped. When the energization of the movement 6 is stopped, the shaft 61 of the movement 6 rotates to a position where the pointer 5 indicates E by the elastic force of a return spring (not shown).

  In the fuel gauge 1 according to the first embodiment of the present invention described above, the decorative ring 8 fixed to the viewing side of the dial 2 is provided with the guide portion 81 and the stopper portion 82 formed by protruding from the decorative ring 8 as characters. The guide portion 81 is fitted to the side 26a which is one side of the through-hole 26 of the dial plate 2 and the stopper portion 82 is fitted to the side 26b which is the other side facing the side 26a. At the same time, the engaging portion 82 a of the stopper portion 82 is engaged with the back surface 27 of the dial 2 and fixed to the dial 2.

  Thereby, when the attachment of the decorative ring 8 to the dial plate 2 is completed, the pair of guide portions 81 and the stopper portion 82 are restrained from moving in the through hole 26, so that the position holding force of the decorative ring 8 is increased. Thus, the mounting position accuracy of the decorative ring 8 can be increased.

  Further, at the time of assembling the decorative ring 8 to the dial plate 2, at least one of the guide portion 81 and the stopper portion 82 can be deformed so as to approach the other.

  As a result, when the guide portion 81 and the stopper portion 82 are inserted into the through hole 26, the force exerted by the guide portion 81 and the stopper portion 82 on the through hole 26 is reduced to prevent the dial 2 from being damaged. As a result, the push-in force required for insertion can be reduced and the assembly workability can be improved.

  Further, in the fuel gauge 1 according to the first embodiment of the present invention, the guide portion 81 and the stopper portion 82 are arranged so as not to overlap each other in the deformation direction during the attaching operation to the dial plate 2.

  As a result, it is possible to reduce the length in the radial direction of the decorative ring 8, which can prevent a part of the through hole 26 from looking into the back of the decorative ring 8, thereby improving the degree of freedom in designing the shape of the decorative ring 8. Is possible.

  In the fuel gauge 1 according to the first embodiment of the present invention described above, the guide portion 81 and the stopper portion 82 are arranged so as not to overlap each other in the deformation direction during the attaching operation to the dial plate 2. However, depending on the shape of the decorative ring 8, the guide portion 81 and the stopper portion 82 may be arranged so as to overlap each other.

  In this case, the width dimension A of the through-hole 26 of the dial 2 is the thickness dimension P of the guide part 81, the deformation margin Q of the guide part 81, the thickness dimension R of the stopper part 82, and the deformation of the stopper part 82 in FIG. This is the sum of generation S. That is, although it is larger than the width dimension A in the fuel gauge 1 according to the first embodiment of the present invention described above, the position holding force of the decorative ring 8 is the same as in the case of the fuel gauge 1 according to the first embodiment of the present invention described above. Can be increased, and the mounting position accuracy of the decorative ring 8 can be increased.
