The bottom 61 has clips 63 integrally formed in positions matching the holes 55. The clips 63 each have a structure formed by vertical bisecting of a columnar body by a groove 64. When the body is attached or detached, the clips 63 are elastically deformed in a shrinking way, and restored to their original form after their largest parts in outer diameter pass the holes 55. In an assembled state, slopes 65 between the largest outer diameter parts of the clips 63 and their root sides and angular parts 56 of the holes 55 of the bottom plate 52 come into contact with each other.

Description

  The present invention relates to an instrument device for vehicles.

  Conventionally, a display mechanism for displaying a measured amount by rotating a pointer located on a display board through an eddy current type drive main body (instrument main body), and a cover member made of a transparent material that covers the display mechanism in a transparent manner, An instrument device for a vehicle is known that includes a case member that forms a space portion that houses a display mechanism in combination with the cover member (for example, Patent Document 1).

  In addition, an indicating instrument (instrument device) that can be attached to and detached from the instrument body and the case member without using a fixing screw has been proposed (for example, Patent Document 2).

JP2011-179830A Japanese Utility Model Publication No. 60-189815

  In this type of vehicle instrument device described in Patent Document 1, in the process of use, moisture enters the space and the inner surface of the cover member becomes cloudy, or dust or dust adheres to the drive body in a harsh usage environment. As a result, there may be a problem that the rotation of the pointer is hindered. In such a case, the above-described problems can be solved by exchanging the cover member and the drive main body.

  However, the drive main body generally has a structure that is fixed to the metal frame of the drive main body by screws from the back side of the case member. Therefore, remove the handle cover, remove the actual vehicle cable connected to the drive body, and after removing the instrument device for the vehicle from the mounting stay of the vehicle, remove the cover member from the case member, and provide it on the back side of the case member The drive main body can be replaced only after the screw is removed. Therefore, the vehicle instrument device described in Patent Document 1 has a problem that the repair work is complicated and time is required for the work.

  In Patent Document 2, although a screw is not used, the instrument body (drive body) and the case member are fixed by bayonet coupling only around the bearing portion of the instrument body. For this reason, when vibration or the like is applied to the instrument device, a burden is easily applied to the main body engaging protrusions and the notch portions of the case member for the bayonet connection. As a result, the case member may be damaged or the engaging protrusion may be damaged. Therefore, when the technology is used in a vibration atmosphere such as for a motorcycle, it is necessary to separately compensate for a lack of strength.

  In addition, the instrument described in Patent Documents 1 and 2 vibrates the main body itself when excessive vibration occurs in the process of use. Has the problem of lowering.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an instrument device that can be easily assembled and disassembled in a short time. Furthermore, an object of this invention is to provide the instrument apparatus excellent in durability.

In order to achieve the above-described object, the instrument device according to the present invention includes:
An instrument body with a pointer to be driven as the rotary shaft rotates;
A dial attached to the upper part of the main frame of the instrument body,
A case body that has an upper case and a lower case and houses the instrument body and the dial,
A bearing portion that pivotally supports the rotating shaft provided on the bottom side of the main body frame of the instrument body,
The lower case includes a through hole provided so that the bearing portion can be inserted, and the lower case for removably fixing a part of the instrument body at a position spaced radially outward from the bearing portion. A fixing member integrally provided from
It is characterized by that.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
As shown in FIG. 1, the instrument 100 includes an upper case 10, a pointer 20, a dial 30, a main body drive unit 40 of the instrument main body M, a main body frame 50 of the instrument main body M, and a lower case 60. Prepare. Note that the instrument 100 in this specification is an instrument device for a vehicle, and in this embodiment, the instrument 100 is described as a speedometer that indicates the traveling speed of the vehicle, but the application of the instrument is not limited to this. In the following description of each embodiment, it is assumed that the upper case 10 is on the front side of the meter 100 and the lower case 60 is on the back side of the meter 100.

  The upper case 10 includes a frame body 11 and a transparent plate 12. The frame body 11 is formed as a lid-like housing having a relatively low height with respect to the lower case 60 using metal or resin. An opening window is provided at the center of the frame body 11, and a transparent plate 12 made of glass or resin is attached to the opening window. Through the transparent plate 12, the user can visually recognize the pointer 20 and the dial plate 30 from the outside of the instrument 100.

  The pointer 20 is attached to a later-described pointer shaft provided in the main body drive unit 40 of the meter main body M protruding from a central hole (insertion hole) provided in the dial plate 30. The illustrated main surface of the dial 30 is a surface on which a numerical value indicating the traveling speed, a description, and the like are displayed. The pointer 20 rotates so as to indicate a numerical value or a scale displayed on the dial 30 according to the traveling speed. For convenience, in FIG. 1, the pointer 20, the dial 30, and the instrument main body M (the main body drive unit 40 and the main body frame 50) are illustrated as being assembled together.

  The instrument main body M includes a main body drive unit 40 that is rotationally driven via a flexible cable for transmitting the rotation of the wheels of the vehicle, for example, and a main body frame 50 that supports the main body drive unit 40. The main body drive unit 40 includes a rotating shaft 41 connected to a flexible cable that rotates according to the traveling speed, a magnet 42 that rotates together with the rotating shaft 41, and a derivative 43 that rotates by an eddy current action generated by the rotational motion of the magnet 42. And a pointer shaft 44 attached to the derivative 43, and each component of the main body driving unit 40 is assembled to the main body frame 50. The main body frame 50 is provided with a bearing portion 51 that rotatably supports the rotary shaft 41. (Described in the embodiment of FIGS. 10 to 12)

  The rotation from the vehicle is transmitted to the rotating shaft 41 via a flexible cable (not shown), the magnet 42 is rotated together with the rotating shaft 41, and the eddy current action generated by the rotating motion of the magnet 42 is guided to the cylindrical derivative 43, A rotational torque proportional to the rotation of the magnet 42 acts on the derivative 43, the rotational torque of the derivative 43 is balanced with the elastic force of a not-shown whisker spring, and the rotational displacement of the pointer 20 corresponding to the rotational speed of the rotary shaft 41 is written. Measurement and display are performed by comparing with scales and numerical values on the plate 30.

  The lower case 60 is a box-shaped housing formed using metal or resin. The lower case 60 includes a center hole 62 in the bottom 61. When the instrument main body M including the main body driving unit 40 and the main body frame 50 is accommodated in the lower case 60, the portion of the bottom plate 52 of the main body frame 50 is placed on the bottom 61 (bottom surface) of the lower case 60. . At this time, the bearing portion 51 that supports the rotating shaft 41 is configured to pass through a center hole 62 provided in the bottom portion 61 and protrude to the outside on the back side of the lower case 60. Further, the lower case 60 is closed by the upper case 10 in a state in which the pointer 20, the dial 30 and the instrument body M are accommodated. FIG. 1 shows a common configuration in each embodiment, and the display of a later-described clip 63 and the like formed integrally with the bottom 61 is omitted.

The assembly of the meter 100 is performed in the following procedure along FIG. The meter main body M (the main body drive unit 40 and the main body frame 50) is assembled in advance as shown in FIG.
A dial 30 is attached to the front side of the instrument body M with screws or the like. At this time, the pointer shaft 44 provided in the meter body M is inserted into the insertion hole provided in the dial plate 30 and protrudes to the front side of the dial plate 30. Next, the pointer 20 is attached to the tip of the pointer shaft 44 protruding to the front side. Next, the meter body M is attached on the bottom surface of the bottom portion of the lower case 60. At this time, the bearing 51 is inserted into the back side of the meter body M through the center hole 62 of the bottom 61 of the lower case 60 so that the body frame 50 and the bottom 61 are in contact with each other. Next, finally, the upper case 10 is attached to the lower case 60 with screws or the like.

  Disassembly of the instrument 100 is performed by the reverse procedure of the above-described assembly. That is, the upper case 10 is removed from the lower case 60, the instrument main body M, the pointer 20 and the dial 30 are removed from the lower case 60. Finally, the pointer 20 and the dial 30 are removed from the instrument main body M. In the case of the repair work of the instrument 100, it is performed in the order of disassembly, parts replacement, and reassembly.

  As shown in FIGS. 2A and 2B, the main body frame 50 is formed in a U shape from a plate material. More specifically, side plates 53 and 53 are erected on both ends of the bottom plate 52, respectively. Such a shape can be formed by a known method such as bending and welding of a plate material.

  The bottom plate 52 includes a central hole 54 at the center thereof. In the center hole 54, a bearing portion 51 for supporting the rotating shaft 41 of the main body driving portion 40 is fitted and fixed by caulking. A part of the circular hole is provided with a convex part and a concave part as shown. In addition, the bottom plate 52 includes four circular holes 55 that are arranged at approximately equal intervals around the rotation shaft 41 of the main body drive unit 40. The inner diameter of each of the holes 55 is smaller than the inner diameter of the circular portion of the center hole 54. In addition, the main body frame 50 is provided with a hole, a convex portion, a concave portion, and the like that are not provided with reference numerals for the combination with other parts of the instrument 100, and the detailed description thereof is omitted in this specification.

  Hereinafter, the shape of the main body frame 50 is simplified and displayed for easy understanding. In the following, the mounting relationship between the main body frame 50 and the lower case 60 will be mainly described. However, since the main body frame 50 is pre-assembled as the meter body M as described above, the mounting relationship between the meter body M and the lower case 60 is described. It is synonymous with.

  As shown in FIGS. 3A and 3B, the bottom portion 61 includes four clips (fixing members) 63 that are formed integrally with the bottom portion 61 and are erected from the bottom surface. The position of the clip 63 is around the center hole 62 and corresponds to each position of the hole 55 arranged in the main body frame 50. Each clip 63 basically has a slit-like two-stage substantially circular columnar body whose outer diameter on the side close to the bottom 61 (base side) is smaller than the maximum outer diameter on the side far from the bottom 61 (tip side). It is erected as a structure that is divided into two in the longitudinal direction (attachment / detachment direction) by the groove 64. The distal end side of the clip 63 is tapered from the maximum outer diameter portion toward the distal end. Further, the stepped portion between the tip side and the root side is a slope 65 whose outer diameter decreases from the tip side toward the root side.

  The inner diameter of the hole 55 of the main body frame 50 is larger than the outer diameter of the base portion of the clip 63 and smaller than the outer diameter of the tip portion, and the slope 65 of the clip 63 is at a position corresponding to the height of the bottom plate 52. Therefore, when the main body frame 50 is assembled to the lower case 60 as shown in the drawing, the inclined surface 65 comes into contact with the corner portion 56 at the upper peripheral edge of the hole 55.

  The clip 63 having the above-described structure functions as a so-called elastically deformable fixing member. As a result, when the main body frame 50 is assembled to the lower case 60, the clip 63 is elastically deformed so that the clip 63 is squeezed as the clip 63 is inserted into the hole 55 along the tapered slope. The maximum outer diameter portion and the maximum width of the divided portion of the clip 63 are formed so as to be able to pass through the hole 55 when the clip 63 is squeezed. Thereby, the tip end side of the clip 63 passes through the hole 55. After the passage, the position of the clip 63 is restored, so that the clip 63 is engaged with the corner portion 56 of the hole 55 and assembled as shown in FIG. On the other hand, when disassembling, the clip 63 is sunk along the slope 65 of the stepped portion by a vertical force (and a force that squeezes the clip 63 externally) that separates the main body frame 50 from the lower case 60. As a result, the maximum outer diameter portion on the tip side passes through the hole 55.

  As described above, according to the present embodiment, the screw conventionally used for fixing the mechanical main body (instrument main body M) from the back side of the lower case becomes unnecessary, and the main body M is attached to the lower case 60. The clip is fixed so as to be detachable (engageable / detachable). At this time, since the slope 65 of the clip 63 and the corner portion 56 of the bottom plate 52 are in contact with each other, the contact area is reduced as in point contact, so that both members can be easily attached and detached. In particular, in this embodiment, since the clip 63 is erected from the bottom surface of the lower case 60, it is preferable that the instrument 100 can be easily assembled and disassembled from the front side. Accordingly, the disassembly and assembly of the repairing operation and the like of the instrument 100 can be facilitated, the time required for the operation can be reduced, and the cost for the repairing operation and the like is reduced. Further, the clip 63 is disposed at a position near the bearing portion 51 in the center of the bottom plate 52 and functions as a positioning member.

  3B shows a shape of the clip 63 having a pointed tip in the cross-sectional view, but the tip may have a flat end surface as shown in FIG. In the above embodiment, four clips 63 are used. However, one or more clips 63 may be disposed within a range satisfying a predetermined fixing function and positioning function.

(Second Embodiment)
As shown in FIGS. 5 (a) and 5 (b), the bottom 61 in the present embodiment is replaced with the clip 63 described above, and a plurality of bottoms 61 formed integrally with the bottom 61 and standing from the bottom. A hook 66 is provided. Three hooks 66 are provided according to the shape of the bottom plate 52. These hooks 66 are positions spaced radially outward from the central portion of the bottom plate 52 through which the bearing portion 51 of the meter body M is inserted, and as shown in FIG. It is provided in the position engaged with.

  The shape of the hook 66 is basically the shape of a prism such as the illustrated quadrangular prism. The surface of the hook 66 on the side facing the bottom plate 52 has a stepped shape like one of the two divisions of the clip 63 described above in the cross-sectional shape. That is, in FIG. 5B, the width on the tip side (maximum width) is larger than the width on the root side. The stepped portion of the maximum width portion and the root side portion is a slope 67. The position of the inclined surface 67 in the height direction corresponds to the height of the bottom plate 52 in the same manner as the inclined surface 65 of the clip 63. The distance between the hooks 66 facing each other across the bottom plate 52 is wider than the width of the bottom plate 52 on the root side and narrower than the width of the bottom plate 52 at the maximum width portion (minimum distance portion). 5A and 5B, the slope 67 of the hook 66 and the corner 57 of the peripheral edge of the bottom plate 52 come into contact with each other. That is, two sets of hooks 66 (one or two per set) facing each other sandwich and fix the bottom plate 52 on the slope 67.

  When the main body frame 50 is assembled to the lower case 60, the two sets of hooks 66 are elastically deformed so as to be opened by a vertical force that inserts the bottom plate 52 between the two sets of hooks 66. Then, the bottom plate 52 passes through the minimum interval portion, and the position of the hook 66 is restored, so that the bottom plate 52 is assembled in the illustrated state. On the contrary, when disassembling, the pair of hooks 66 are elastically deformed so as to be opened by a vertical force separating the bottom plate 52 from the bottom 61. Then, when the bottom plate 52 passes through the minimum interval portion, the bottom plate 52 is removed and the position of the hook 66 is restored.

  Even with the configuration of the present embodiment, as in the first embodiment, the main body frame 50 of the meter body M and the lower case 60 are detachably engaged with each other by the hook 66 without the need for fixing screws. Fixed. At that time, a small contact area is fixed between the slope 67 of the hook 66 and the corner 57 of the bottom plate 52. Therefore, it becomes easy to disassemble and assemble the measuring instrument 100 and the like, and it is possible to reduce the time required for the operation. Further, since the hook 66 engages with the position away from the bearing portion 51 at the center of the bottom plate 52, that is, in the example of the present embodiment, it is effective as a detent for the main body frame 50. Can function.

  Depending on the shape of the bottom plate 52 and the necessary fixing function, the hooks 66 may be provided in a number other than the above three. For example, as shown in FIG. 6A, the number of hooks 66 may be four (or five or more), or two outer edges of the bottom plate 52 facing each other. Moreover, as shown in FIG.6 (b), it is good also as providing the notch 58 in the part which the hook 66 engages in the baseplate 52. FIG.

(Third embodiment)
As shown in FIG. 7A, the above-described clip 63 and hook 66 can be used in combination.

  The clip 63 fixes the main body frame 50 to the lower case 60 at a position close to the rotation shaft 41. In contrast, the hook 66 fixes the main body frame 50 to the lower case 60 at the periphery of the bottom plate 52. By combining these, it is possible to increase the fixing strength. Further, in order to satisfy a predetermined fixing strength, the number of the clips 63 and the hooks 66 is not necessarily limited to that shown in the drawing, and may be determined as necessary.

  Since the hook 66 has a fixing function, the hole 55 on the main body frame 50 side is formed integrally with the bottom 61 as shown in FIG. Alternatively, a truncated cone-shaped positioning pin 70 may be used. Also, the number of positioning pins 70 may be two, for example, as much as necessary for the positioning function.

(Fourth embodiment)
In the present embodiment, in addition to the function of fixing the main body frame 50 to the bottom 61 of the lower case 60, a detent is provided at the bottom peripheral edge of the main body frame 50.

  As shown in FIGS. 8A and 8B, the bottom plate 52 of the main body frame 50 is fixed to the bottom 61 of the lower case 60 by the clip 63 described in the first embodiment. In addition, four detents 68 are provided at the corners of the bottom 61.

  Referring also to FIG. 9 (a), the rotation stopper 68 is integrated with the bottom portion 61 so as to form an L shape when viewed from the front side toward the bottom portion 61, that is, along the attaching / detaching direction. Standing from the bottom 61. The detents 68 are respectively arranged at positions where the L-shaped corners 69 and the adjacent inner surfaces engage with the corners of the main body frame 50.

  Since the rotation stopper 68 is L-shaped when viewed from the front side, the rotation stopper 68 functions as a rotation stopper of the main body frame 50 with respect to the lower case 60, and can also serve as a guide for assembly and disassembly. Therefore, according to the present embodiment, it is possible to add a detent without increasing the number of parts while ensuring the same ease of repair as in the above-described embodiments.

  In addition, in the combination of the fixing function and the anti-rotation function, the number of the clips 63 and the anti-rotation 68 can be determined as necessary for each function. For example, as shown in FIG. 9B, for example, two clips 63 and two rotation stoppers 68 may be provided and arranged so as to be aligned diagonally when viewed from above.

  Further, from the viewpoint of the combination of the fixing function and the rotation prevention function, the hook 66 may be combined with the rotation prevention 68 instead of the clip 63 described above. Also in that case, the numbers of hooks 66 and rotation stoppers 68 may be determined arbitrarily.

(Fifth embodiment)
In the above-described embodiments, the structure of the attachment portion between the main body frame 50 and the lower case 60 has been mainly described. In addition, it is preferable for an instrument device used in a vibration environment such as for a vehicle to suppress the occurrence of needle shake due to excessive vibration, finger change, powder blowing due to sliding portion wear, and the like. Therefore, in this embodiment, a buffer mechanism used in combination with the above-described structure will be described.

  As shown in FIG. 10A, a buffer member 81 is provided so as to surround the outer peripheral edge of the dial 30. The buffer member 81 is formed of a material having elasticity and impact resistance such as rubber. The buffer member 81 forms an annular body in which a groove 82 that opens toward the center of the dial 30 is formed on the entire circumference in the cross section shown in the drawing. The groove 82 of the buffer member 81 is fitted to the outer peripheral edge of the dial plate 30, and in this state, the upper and lower surfaces and the outer peripheral surface of the buffer member 81 are formed by the frame body 11 of the upper case 10 and the lower case 60. It is accommodated so as to be sandwiched in the space.

  Further, as shown in FIG. 10B, about 2 to 4 mounting plates 13 and bosses 73 are provided in the circumferential direction at corresponding positions of the outer peripheral edge portions of the frame body 11 and the lower case 60. . A screw hole corresponding to the screw 86 is formed in the boss 73. Thereby, the upper case 10 is assembled to the lower case 60 from above using the screws 86, and the buffer member 81 is fixed. In the present embodiment, the mounting plate 13 and the boss 73 are illustrated as simple plates, but it is possible to add a reinforcing rib or the like, for example.

  With the configuration as in this embodiment, the buffer member 81 is interposed between the dial 30 and the lower case 60 (and the upper case 10), thereby functioning as a steady stop for the dial 30 against vibration. To do. This protects the pointer 20 and the main body drive unit 40 in addition to the dial 30 from vibration. Therefore, the main body drive unit 40 and the like can be effectively protected against vibration by engaging not only on the back side of the main body drive unit 40 as in the above-described embodiments but also on the front side. . Further, as shown in the figure, the buffer member 81 is provided in a form that can be easily assembled and disassembled. Furthermore, it is preferable to combine such a buffer member 81 with a mechanism for fixing and rotating, since it does not impair the operational effect of the repair work and the like in each of the above-described embodiments.

  In FIG. 10A, the hook 66 is used for fixing the main body frame 50 and the lower case 60 as an example. However, the fixing function and the rotation prevention function described in the above embodiments are provided. As described above, the clip 63, the rotation stopper 68, and the like can also be used (the same applies to FIGS. 11 and 12).

(Sixth embodiment)
As shown in FIG. 11, an intermediate support member 83 is sandwiched between the frame 11 of the upper case 10 and the lower case 60. The intermediate support member (look-back member) 83 is made of metal or resin. The intermediate support member 83 includes a columnar protrusion 84 that protrudes toward the dial 30 at a position corresponding to the outer peripheral edge of the dial 30. A buffer member 85 having a corresponding concave portion is attached to the convex portion 84. The buffer member 85 is formed of the same material as the buffer member 81 described above.

  When the instrument 100 is assembled as shown in FIG. 11, the buffer member 85 comes into contact with the front surface of the dial 30. Thereby, like the fifth embodiment, the buffer member 85 functions as an anti-sway of the dial 30 against vibration. Note that the fixing of the upper case 10 and the lower case 60 using the mounting plate 13, the boss 73, and the screw 86 is the same as the example of FIGS. 10 (a) and 10 (b).

(Seventh embodiment)
As shown in FIG. 12, the bottom 61 of the lower case 60 includes a plurality of columns 71 that are integrated with the bottom 61 and are erected from the bottom. The support 71 is disposed on the outer peripheral edge of the dial 30. The support 71 has the same shape as the protrusion 84 in the example of FIG. 11, and includes a protrusion 72 that protrudes from the tip of the support 71 toward the dial 30. And the buffer member 85 similar to the example of FIG.

  When the instrument 100 is assembled as shown in FIG. 12, the buffer member 85 comes into contact with the back surface of the dial 30. Thereby, like the sixth embodiment, the buffer member 85 functions as a steady stop for the dial 30 against vibration. Note that the fixing of the upper case 10 and the lower case 60 using the mounting plate 13, the boss 73, and the screw 86 is the same as the example of FIGS. 10 (a) and 10 (b).

  The present invention is not limited to the above-described embodiments and specific examples, and various modifications and applications are possible.

  For example, in FIG. 1, the upper case 10 and the lower case 60 have a quadrangular shape when viewed from the front (upper side in FIG. 1).

  Further, in each of the above-described embodiments, the clip 63, the hook 66, the rotation stopper 68, the positioning pin 70, and the support column 71 are illustrated so as to be integrally formed with the bottom portion 61. However, different members from the bottom portion 61 are illustrated. It is good also as attaching so that isolation | separation with the bottom part 61 is unnecessary at the time of restoration.

  In each of the above-described embodiments, the clip 63 and the hook 66 are erected from the bottom 61 of the lower case 60. In addition, a member having the same function as the clip 63 and the hook 66 may be provided in the main body frame 50, and a portion that engages with these clips and the like may be provided in the lower case 60.

  Further, in each of the above-described embodiments, the center hole 54 corresponding to the clip 63 is a circular hole, and the side portion or notch 58 of the bottom plate 52 corresponding to the hook 66 is configured to be linear. The shapes of these engaging portions are not limited to the above example. Various shapes such as an arc shape, a straight line shape, and a groove shape can be used. In that case, the clip or hook that is elastically deformed may have any shape as long as the fixing function is exhibited by the engagement and the ease of attachment and detachment is ensured.
