Refer to fig. 9. The vehicle meter 100 includes: a metal case 101; and a sum calculator 110, the sum calculator 110 being supported on the housing 101 and indicating a travel distance. The accumulation calculator 110 includes: an accumulation calculator shaft member 111, the accumulation calculator shaft member 111 being fixed to the housing 101; a plurality of character wheels 112, the plurality of character wheels 112 being rotatably provided on the sum calculator shaft member 111, numerical values being recorded on an outer surface of the character wheels 112; a pinion holder 113, the pinion holder 113 being disposed between the character wheels 112, and being rotatably disposed on the sum calculator shaft member 111.

Refer to fig. 10. The pinion holder 113 rotatably supports a pinion 114, and the pinion 114 is disposed so as to straddle between the character wheels 112 disposed on the right and left sides. Since the character wheel 112 provided on the right side rotates 1 rotation, the numerical value of the character wheel 112 provided on the left side via the pinion gear 114 goes to 1.

Refer to fig. 9. The assembly of the vehicle meter 100 to the housing 101 is performed by: the totalizer shaft member 111 is assembled to a shaft member support portion 101a formed in the housing 101 while hooking claw portions 113a formed in the pinion holder 113 to the top surface of the housing 101 and aligning the pinion holder 113 at a correct position.

Here, the pinion holder 113 is rotatably mounted on the totalizer shaft section 111.

The invention described in claim 1 provides a meter for a vehicle, including: a rotating body that rotates in linkage with rotation of the wheel; an accumulation calculator for rotating the character wheel on which the numerical value is recorded according to the rotation of the rotating body to indicate a travel distance; a housing rotatably supporting the rotating body and the sum calculator;

the above-mentioned accumulation calculator includes: an addition calculator shaft member fixed to the housing; a plurality of said character wheels rotatably disposed on said totalizer shaft member; a pinion holder which is provided between the character wheels and is rotatably provided on the addition calculator shaft member; a pinion gear rotatably supported by the pinion holder and spanning between the character wheels provided on the left and right sides;

the numerical value in the character wheel on the left side is further 1 by the pinion gear as the character wheel on the right side rotates 1 revolution,

wherein said housing includes a receiving portion that receives at least a lower half of said totalizer;

the receiving portion includes: a shaft member support portion on which the totalizer shaft member is supported; a front wall portion extending along a front surface of the character wheel; a rear wall portion extending along a rear surface of the character wheel;

the pinion holder includes: a retainer body portion having a circular shape with the totalizer shaft member as a center; a front projecting portion projecting from the holder main body portion to the vicinity of the front wall portion; and a rear protruding portion protruding from the holder body portion to a vicinity of the rear wall portion, the rear protruding portion being prevented from rotating by the front wall portion and the rear wall portion.

As defined in claim 2, preferably, the front bottom end of the front protruding portion is formed with a downward slope toward the rear, and the rear bottom end of the rear protruding portion is formed with a downward slope toward the front.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the invention of claim 1, the pinion holder comprises: a front protruding portion protruding from the holder main body portion to the vicinity of the front wall portion; and a rear wall projecting portion projecting from the holder main body portion to the vicinity of the rear wall portion. When the pinion holder is dislocated in the rotational direction, the front projection contacts the front wall portion, or the rear projection contacts the rear wall portion. Since the pinion holder is rotatably provided on the addition calculator shaft member, the protruding portion formed on the holder rotates by coming into contact with the wall portion formed on the receiving portion. By further pressing in the totalizer, the pinion cage is guided to the correct position by the wall formed on the receiving portion. Thus, it is not necessary to press the pinion holder and assemble the pinion holder to the housing during the mounting operation of the totalizer. A vehicle meter in which a totalizing calculator can be easily assembled to a housing can be provided.

According to the invention of claim 2, the front bottom end portion of the front protruding portion is formed with a downward slope toward the rear, and the rear bottom end portion of the rear protruding portion is formed with a downward slope toward the front. If the pinion holder is dislocated in the rotational direction when the accumulation calculator is assembled to the housing, the front bottom end portion or the rear bottom end portion comes into contact with the housing. These portions are tapered, and therefore, the pinion holder can be easily rotated. The assembling workability can be further improved.

Embodiments of the present invention will be described below with reference to the drawings. In the description, the left and right refer to the left and right with reference to the occupant of the vehicle, and the front and rear refer to the front and rear with reference to the traveling direction of the vehicle.

(examples)

Refer to fig. 1 to 3. The vehicle meter 10 is used for a two-wheeled vehicle, for example, and the cumulative vehicle speed meter 50 and the cumulative calculator 70 are assembled to the housing 20. The vehicle speed meter 50 is an eddy current type meter that indicates the traveling speed of the vehicle. The accumulation calculator 70 indicates the travel distance of the vehicle.

Reference is made to fig. 4. The housing 20 is composed of a plate-shaped base 21 and a resin cover 30 covering the base 21.

The accumulation vehicle speed meter 50 includes: a metal tubular member 51, the tubular member 51 being fixed to the base 21; a metal slide bearing 52, the slide bearing 52 being provided on the inner periphery of the tubular member 51; a 1 st rotation shaft 53 (rotation body 53), the 1 st rotation shaft 53 being rotatably supported by the slide bearing 52; a cup-shaped magnetic conductor 54, the magnetic conductor 54 being fixed to an upper portion of the 1 st rotating shaft 53; a magnet 55, the magnet 55 being received in the magnetic conductor 54 and fixed to an upper portion of the 1 st rotating shaft 53; a slide bearing 56, the slide bearing 56 being received in a hole formed at the tip end of the 1 st rotating shaft 53; a 2 nd rotation shaft 57, a bottom end of the 2 nd rotation shaft 57 being rotatably supported on the sliding bearing 56; an oil cup 62, the oil cup 62 being fixed to the 2 nd rotation shaft 57, and damping oil 61 being filled in the oil cup 62; a rotor 63, the rotor 63 being fixed to an outer periphery of the oil cup 62; a balance spring 64 (biasing member 64), the balance spring 64 being fixed to the tip of the 2 nd rotating shaft 57; and a worm 65, wherein the worm 65 meshes with the wheel portion 53a formed on the 1 st rotation shaft 53.

Refer to fig. 5. The accumulation calculator 70 includes: an integrating calculator shaft member 71, the integrating calculator shaft member 71 being fixed to the lid 30 (see fig. 2); 6 character wheels 72, the character wheels 72 being rotatably provided on the sum calculator shaft member 71; pinion holders 73, the pinion holders 73 are respectively disposed between these character wheels 72, and are rotatably disposed on the totalizer shaft member 71; and pinion gears 74 rotatably supported by these pinion holders 73, the pinion gears 74 being provided so as to straddle between the character wheels 72 provided on the left and right sides, respectively.

Refer to fig. 4. The base 21 is formed by press-forming a cold-rolled steel sheet, for example. The base 21 includes an insertion hole 21a, and a cylindrical member 51 is inserted substantially in the middle of the insertion hole 21 a.

The cover 30 is an injection molded article formed by injection molding, for example, and includes: a lid wall portion 31, the lid wall portion 31 rising from the base portion 21; a top plate portion 32, the top plate portion 32 extending from the top end of the lid wall portion 31 in parallel with the base portion 21; a box-shaped receiving portion 40, the receiving portion 40 being adjacent to the top plate portion 32 and receiving the cumulative-sum calculator 70. The resin of the lid body 30 may be polybutylene terephthalate.

In the top plate portion 32, a circular hole insertion hole 32a is opened in the axis CL of the 1 st rotating shaft 53. The 2 nd rotating shaft 57 made of metal is inserted into the insertion hole 32a. That is, the 2 nd rotating shaft 57 is provided on the same axis CL as the 1 st rotating shaft 53.

The top plate 32 includes a cylindrical stopper 32b extending downward. The tip of the stopper 32b is immersed in the damping oil 61, and rotation of the rotor 63 is suppressed. The stopper 32b restricts the sliding direction of the rotor 63 by colliding with the bottom surface of the oil cup 62.

The receiving portion 40 is formed in a box shape, and an upper side thereof is opened in such a manner as to receive a substantially lower half portion of the sum calculator 70. The receiving portion 40 includes: a bottom portion 41; a front wall portion 42, the front wall portion 42 rising substantially perpendicularly from a front end portion of the bottom portion 41; and a rear wall portion 43, the rear wall portion 43 rising from a rear end of the bottom portion 41.

The bottom portion 41 has a front portion formed in a planar shape, and a rear portion formed in a 90 ° circular arc shape along the character wheel 72.

The front wall portion 42 includes a front guide portion 42a at a top end thereof, and the front guide portion 42a is formed at a slope descending toward the rear so that the accumulation calculator 70 can be easily received in the receiving portion 40.

Similarly to the front guide portion 42a, the front end of the rear wall portion 43 may be formed as a rear guide portion 43a (see fig. 8) formed with a slope that decreases forward so that the sum calculator 70 can be easily received in the receiving portion 40.

Refer to fig. 2. The left and right ends of the receiving portion 40 are closed by a left wall 44 and a right wall 45, respectively.

Refer to fig. 3. A substantially U-shaped shaft member support portion 44a, which is open upward, is formed on the left wall portion 44 so as to support the totalizer shaft member 71. The shaft member support portion 44a is a portion where the totalizer shaft member 71 can be assembled from above. The left wall portion 44 is integrally formed with a flexible portion 44b and a stopper 44c, the flexible portion 44b being flexible in the front-rear direction, and the stopper 44c is provided at the distal end of the flexible portion 44b and constitutes an extraction prevention portion of the totalizer shaft member 71.

A tapered surface portion 44d is formed from the tip of the stopper 44c, and the tapered surface portion 44d is inclined with respect to the extending direction of the shaft member support portion 44 a.

Refer to fig. 2. A shaft member insertion hole 45a is formed in the right wall portion 45, and a right end portion of the totalizer shaft member 71 is inserted into the shaft member insertion hole 45 a.

The shaft member support portion 44a may be formed on the right wall portion 45, and the shaft member insertion hole 45a may be formed on the left wall portion 44. In this case, the flexible portion 44b, the stopper portion 44c, and the tapered portion 44d are integrally formed on the right wall portion 45.

The magnet 55 is a sintered magnet made of, for example, alNiCo (ァルニコ: alNiCo), magnetized in the radial direction, and the cable from the vehicle is rotated at the number of revolutions proportional to the traveling speed of the vehicle by being inserted into the 1 st rotating shaft 53.

The 2 nd rotation shaft 57, the oil cup 62, and the rotor 63 are integrally connected by insert molding.

The rotor 63 is made of a nonmagnetic metal such as aluminum, and is formed into a cup shape by press molding. The rotor 63 is provided so as to cover the magnet 55 without contacting the magnet 55.

The end of the balance spring 64 is fixed to the lid body 30 by heat fastening or the like.

The worm 65 rotates by the rotation of the wheel portion 53 a. The rotational force of the worm 65 is transmitted to the accumulation calculator 70. That is, the value indicated by the accumulation calculator 70 is proportional to the rotation amount of the worm 65. The mechanism for transmitting the rotational force of the 1 st rotation shaft 53 to the totalizer 70 may employ a well-known mechanism.

A flexible cable may be connected to the bottom end of the 1 st rotation shaft 53. The flexible cable transmits the rotation of the wheel to the 1 st rotation shaft 53. That is, the 1 st rotation shaft 53 rotates in conjunction with the rotation of the wheel.

When the two-wheeled vehicle travels, the 1 st rotation shaft 53 rotates, and the magnetizer 54 and the magnet 55 fixed to the 1 st rotation shaft 53 rotate integrally. On the other hand, the base 21, the tubular member 51, and the slide bearing 52 do not rotate.

Eddy current is generated by the rotation of the 1 st rotation shaft 53, the magnet 55, and the magnetic conductor 54. The eddy current causes a force to act on the rotor 63 in the rotational direction. The eddy current increases with an increase in the speed at which the magnet 55 rotates. If the eddy current increases, the rotor 63 rotates against the biasing force of the balance spring 64. If the rotor 63 rotates, the 2 nd rotation shaft 57 and the oil cup 62 rotate. As the 2 nd rotation shaft 57 rotates, the pointer 67 (see fig. 1) fixed to the tip of the 2 nd rotation shaft 57 also rotates. On the other hand, the lid body 30, the stopper 32b and the hairspring 64 do not rotate.

If the two-wheeled vehicle decelerates, the rotation speed of the 1 st rotation shaft 53 also decreases. Thus, the eddy current is small. By the biasing force of the balance spring 64, the 2 nd rotation shaft 57 rotates toward the opposite direction to that at the time of acceleration. If the two-wheeled vehicle stops, the 2 nd rotation shaft 57 and the pointer 67 return to the position before the two-wheeled vehicle travels.

The oil cup 62 is rotatable and the stopper 32b cannot be rotated. Inside the oil cup 62, the damping oil 61 is filled. Due to the rotation of the magnet 55, a force is applied to the oil cup 62 in the rotational direction. At this time, the damping oil 61 and the stopper 32b act on the oil cup 62 in a direction to suppress the rotation. The force for suppressing the rotation acts on the oil cup 62 both in the case of acceleration and in the case of deceleration. This suppresses abrupt rotation of the 2 nd rotation shaft 57 and the rotor 63. By suppressing the abrupt rotation, the runout of the pointer 67 is suppressed.

Refer to fig. 5 and 6. The character wheel 72 is cylindrical and has a right and left partition wall 72a at the center. On the circumferential surface of the character wheel 72, a numerical value 72b showing a travel distance is shown. The right side surface portion of the character wheel 72 is in the form of an internal gear. The left side surface of the character wheel 72 is in the form of an internal gear, in which teeth 72d of the number (2) of 1/10 of the teeth 72c formed on the right side surface are formed. All of the character wheels 72 have the same structure.

Character wheels

72R and 72L are provided on the left and right sides of the pinion holder 73, respectively (in this stage, R is a suffix indicating the right and L is a suffix indicating the left). As the right character wheel 72R rotates with reference to the pinion holder 73, the teeth 72d formed on the left side surface come into contact with the pinion 74. With further rotation of the right character wheel 72R, the pinion gear 74 is rotated. The pinion gear 74 is disposed so as to straddle between the left and

right character wheels

72R and 72L. Further, on the right side face portion of the right character wheel 72R, teeth 72c are formed integrally. Thereby, the right character wheel 72R is rotated by the pinion gear 74. Thereby, the numerical value 72b described on the outer surface of the right character wheel 72R goes to 1. That is, the character wheel 72L provided on the left side rotates 1 revolution with the character wheel 72R provided on the right side, and the numerical value 72b advances by 1 by the pinion gear 74.

Reference is made to fig. 4. Pinion holder 73 includes: a holder body 73a, the holder body 73a having a circular shape with the totalizer shaft member 71 as a center; a front projecting portion 73b projecting from the holder body portion 73a to the vicinity of the front wall portion 42; a rear projecting portion 73c projecting from the holder body portion 73a to the vicinity of the rear wall portion 43; a contact preventing portion 73d which prevents the character wheel 72 continuously formed on the upper portion of the rear protrusion 73c from contacting the hairspring 64; and a pinion supporting portion 73e, the pinion supporting portion 73e supporting the pinion 74.

The front bottom end 73f of the front protruding portion 73b is formed with a downward slope toward the rear. The rear base end portion 73r of the rear protruding portion 73c is formed with a slope descending toward the front.

Referring to fig. 7, a method of assembling the accumulation calculator 70 to the receiving portion 40 will be described. As shown in fig. 7 (a), first, one end portion (right end portion) of the totalizer shaft member 71 is inserted into the shaft member insertion hole 45 a. Next, the other end portion (left end portion) of the totalizer shaft member 71 is assembled to the shaft member support portion 44 a. Since the shaft member support portion 44a opens upward, the totalizer shaft member 71 is assembled from above.

As shown in fig. 7 (b), the bending portion 44b is bent by press-fitting the totalizer shaft member 71. By further pressing down, the totalizer shaft member 71 is assembled to the shaft member support portion 44a as shown in fig. 7 (c). In a state where the totalizer shaft member 71 is assembled to the shaft member support portion 44a, the flexible portion 44b is not flexed. In this state, the stopper 44c is positioned above the totalizer shaft member 71, and prevents the totalizer shaft member 71 from being pulled out.

Referring to fig. 8 (a). The pinion holder 73 is provided rotatably with respect to the cumulative counter shaft member 71. Thus, when pinion carrier 73 is received in receiving portion 40, pinion carrier 73 is rotatable.

Refer to fig. 8 (b). If the pinion holder 73 rotates, the front projection 73b contacts the front wall portion 42 (or the rear projection 73c contacts the rear wall portion 43). In this state, if the pinion holder 73 is lowered, the front projection 73b is guided to the correct position by the front wall 42 (or the rear wall 43) as shown in fig. 8 (c). By guiding the front projection 73b to the correct position, of course, the rear projection 73c is also set at the correct position.

The present invention described above achieves the following effects.

Refer to fig. 4. The shaft member support portion 44a is a portion to which the cumulative counter shaft member 71 can be attached from above. In addition, the pinion carrier 73 includes: a front projecting portion 73b projecting from the holder body portion 73a to the vicinity of the front wall portion 42, and a rear projecting portion 73c projecting from the holder body portion 73a to the vicinity of the rear wall portion 43. The accumulation calculator 70 is assembled to the housing 20 from above the receiving portion 40. At this time, when the pinion holder 73 is shifted in the rotational direction, the front projection 73b contacts the front wall 42, or the rear projection 73c contacts the rear wall 43. Since the pinion holder 73 is rotatably provided on the totalizer shaft member 71, the

projections

73b, 73c formed on the pinion holder 73 rotate by coming into contact with the

wall portions

42, 43 formed on the receiving portion 40. By further depressing the accumulation calculator 70, the pinion holder 73 is guided to the correct position by the

wall portions

42, 43 formed on the receiving portion 40. Thus, it is not necessary to assemble the totalizer 70 to the housing 20 while pressing the pinion holder 73 at the time of the work of attaching the totalizer 70. The meter 10 for a vehicle can be provided in which the accumulation calculator 70 can be easily assembled to the housing 20.

The front bottom end 73f of the front protruding portion 73b is formed with a downward slope toward the rear, and the rear bottom end 73r of the rear protruding portion 73c is formed with a downward slope toward the front. If the pinion holder 73 is dislocated in the rotational direction when the totalizing calculator 70 is assembled to the housing 20, the front base end portion 73f or the rear base end portion 73r comes into contact with the housing 20. Since these portions are tapered, the pinion holder 73 can be easily rotated. The assembling workability can be further improved.

Further, the front wall portion 42 includes a front guide portion 42a at a tip end thereof, the front guide portion 42a being formed with a slope descending in the rearward direction so that the sum calculator 70 can be easily received in the receiving portion 40, and/or the rear wall portion 43 includes a rear guide portion at a tip end thereof, the rear guide portion being formed with a slope descending in the forward direction so that the sum calculator 70 can be easily received in the receiving portion 40. When the sum calculator 70 is assembled to the cover 30, the pinion holder 73 can be guided to the correct position more easily.

Refer to fig. 3. In the cover 30 (the housing 20), a flexible portion 44b that is flexible in a direction away from the cumulative counter shaft member 71 and a stopper 44c that is located at the tip of the flexible portion 44b and covers the upper side of the cumulative counter shaft member 71 are integrally formed. The situation that the totalizer shaft member 71 is drawn out from the shaft member supporting portion 44a can be prevented by a simple structure without increasing the number of components.

The shaft member support portion 44a is substantially U-shaped, has a width slightly larger than the diameter of the totalizer shaft member 71, and is opened upward. In the stopper 44c, a tapered surface portion 44d inclined with respect to the direction in which the shaft member support portion 44a extends is formed opposite to the tip end. By pressing down the cumulative calculator shaft member 71, the cumulative calculator shaft member 71 abuts against the tapered surface portion 44 d. By further pressing down, the flexure 44b is flexed. That is, by pressing down the cumulative calculator shaft member 71, the flexible portion 44b is flexed and the stopper 44c is displaced, so that the cumulative calculator 70 can be easily assembled to the lid body 30.

Further, a 2 nd rotation shaft 57 (pointer rotation shaft 57) for supporting the pointer 67 is provided in the vicinity of the sum calculator 70, and the 2 nd rotation shaft 57 is offset in the return direction of the pointer 67 by the balance spring 64. At least a portion of balance spring 64 is positioned above character wheel 72. The pinion holder 73 has a contact prevention portion 73d, and the contact prevention portion 73d protrudes between the character wheel 72 and the hairspring 64 based on a side view of the totalizer 70, and prevents the hairspring 64 from contacting the outer surface of the character wheel 72. The influence of the vibration of the engine or the like affects the balance spring 64. There is a risk that the hairspring 64 vibrates toward the outer surface of the character wheel 72, and when it comes into contact with the outer surface of the character wheel 72, the numerical value printed on the outer surface of the character wheel 72 is scraped (see fig. 1). The pinion holder 73 has a contact preventing portion 73d protruding between the character wheel 72 and the hairspring 64. This prevents the hairspring 64 from contacting the outer surface of the character wheel 72, thereby preventing the scraping of the numerical value.

The vehicle meter of the present invention has been described by taking the case of being mounted on a two-wheeled vehicle as an example, but is applicable to four-wheeled vehicles and other cases, and is not limited to these forms.

The present invention is not limited to the embodiments as long as the effects and effects are achieved.
