Description

  The present invention relates to an improvement in the mounting structure of a vehicle unlocking mechanism.

  A motorcycle has been put to practical use in which a case is attached to the body cover, the case is closed with a lid, and small items can be taken in and out of the case by opening the lid. It is desirable that the lid be locked by a lock mechanism.

  Various structures have been proposed for the lock mechanism, and a structure that directly unlocks with a key is known (see, for example, Patent Document 1 (FIGS. 1 and 2)).

  As shown in FIG. 1 of Patent Document 1, a sheet (1) (numbers in parentheses indicate symbols described in the Patent Document; the same applies hereinafter) is locked by a cylinder lock (7). As shown in FIG. 2 of the same document, when the lock plate (8) is turned and fitted into the striker (11), the locked state is obtained. When the lock plate (8) is turned in the opposite direction, it is unlocked.

The structure is simple. As shown in FIG. 1 of the document, the cylinder lock (7) is disposed at the rear portion of the seat (1) and at the center of the vehicle width. That is, there is no degree of freedom in the arrangement of the cylinder lock (7).
There are many vehicles to which a grab rail or carrier is attached immediately after the seat (1). Due to the presence of the cylinder lock (7), it is necessary to shift the mounting position of the grab rail and the carrier toward the rear of the vehicle.

Therefore, a structure has been proposed in which the lock mechanism and the lock / unlock mechanism are made independent of each other and the lock / unlock mechanism can be placed at an arbitrary position (see, for example, Patent Document 2 (FIGS. 2 and 3)).
As shown in FIG. 2 of Patent Document 2, a lock unlocking mechanism (90) is disposed at a position away from the lock mechanism (80). The lock unlocking mechanism (90) is included in the main key device (40). The lock unlocking mechanism (90) can be arranged at an arbitrary position.

  Incidentally, as shown in FIG. 3 of the same document, the main key device (40) including the lock / unlock mechanism is fixed to the bracket (92) using screws (93). The bracket (92) extends from the head pipe (11a). That is, the lock unlocking mechanism is fixed to the vehicle body frame via the bracket (92).

  When the attachment site of the lock / unlock mechanism is away from the vehicle body frame, the bracket (92) is necessarily long and heavy. Such a long and heavy bracket (92) increases the weight of the vehicle and increases the procurement cost and mounting cost of the bracket.

However, in vehicles that require weight reduction and cost reduction, a structure that replaces the structure of Patent Document 2 is required.
That is, there is a demand for a lock / unlock mechanism mounting structure in which the lock mechanism and the lock / unlock mechanism are made independent of each other and the bracket can be omitted.

JP-A-10-7048 JP 2003-89370 A

  An object of the present invention is to provide a lock / unlock mechanism mounting structure in which a lock mechanism and a lock / unlock mechanism are made independent of each other, and a bracket for supporting the lock / unlock mechanism can be omitted.

According to the first aspect of the present invention, an opening / closing member made of a lid or a seat is attached to a vehicle body cover that covers the vehicle body, and a lock mechanism that locks the opening / closing member in a closed position is provided in the vehicle body. Is provided with an unlocking mechanism for unlocking the lock mechanism, and an operation cable comprising an inner cable and an outer cable for accommodating the inner cable movably in the axial direction is passed from the lock unlocking mechanism to the lock mechanism. Then, by inserting a key into the key hole of the lock unlocking mechanism and turning a cylinder having the key hole at one end, the inner cable is operated by an operation portion provided at the tip of the cylinder, and the lock mechanism is unlocked. In the mounting structure of the vehicle unlocking mechanism to be locked,
The outer cylinder that rotatably supports the cylinder is integrally formed with a flange at a portion on the key hole side. When the outer cylinder is inserted into a cylinder mounting hole provided in the vehicle body cover, the outer cylinder is formed on the outer surface of the vehicle body cover. The outer cylinder holding member that contacts the inner surface of the vehicle body cover is attached to the inserted outer cylinder, and the vehicle body cover is sandwiched between the outer cylinder holding member and the flange, The lock unlocking mechanism is fixed to the vehicle body cover,
The outer cylinder holding member includes an outer cable support portion that supports the outer cable.

  In the invention according to claim 2, a key cylinder cover surrounding the lock / unlock mechanism is attached to the inner surface of the vehicle body cover, and an engagement portion capable of stopping the tip of the outer cylinder holding member is provided on the key cylinder cover. It is characterized by.

  In the invention which concerns on Claim 3, an outer cable support part is a substantially U-shaped hole formed in an outer cylinder holding | suppressing member in the form by which one end is open | released, and the outer cable stopped by this substantially U-shaped hole is substantially U-shaped. The key cylinder cover is provided with a wall for preventing the hole from coming out of the hole.

  The invention according to claim 4 is characterized in that the key cylinder cover is a one-piece part formed by plastic deformation of a single steel plate including the engaging portion.

  In the invention according to claim 1, the lock / unlock mechanism is fixed to the vehicle body cover by sandwiching the vehicle body cover between the outer cylinder holding member and the collar portion. That is, no bracket is required.

  In addition, in order to fix the lock unlocking mechanism to the vehicle body cover, a lock unlocking mechanism is attached to the vehicle body cover in advance, and one end of the operation cable is connected to the lock unlocking mechanism in the vehicle assembly line. Therefore, the vehicle assembly line can be simplified.

  Furthermore, one end of the operation cable can be supported by the outer cylinder holding member. In general, an operation cable is fixed to a vehicle body frame or a vehicle body cover via a locking member such as a hook. According to the present invention, since one end of the operation cable is stopped using the outer cylinder holding member, it is not necessary to prepare a separate locking member.

  In the invention according to claim 2, the lock unlocking mechanism is enclosed by the key cylinder cover. The key cylinder cover serves as a protector of the lock / unlock mechanism, and external force is applied to the key cylinder cover, but it does not reach the lock / unlock mechanism. There is no need to make the lock / unlock mechanism robust, and the lock / unlock mechanism can be easily reduced in size and weight.

Further, since the outer cable support portion is provided, the outer cylinder holding member extends to the outer cable like a cantilever beam starting from the outer cylinder. The cantilever beam has a large deflection and deflection at the tip, so that it is necessary to increase the rigidity as a whole as a countermeasure. This increases the weight of the outer cylinder holding member.
In this regard, in the present invention, the tip of the outer cylinder holding member is fixed to the key cylinder cover. Since both ends of the outer cylinder holding member are supported, even if it is thin, bending and deflection are reduced. As a result, the outer cylinder holding member can be reduced in size and weight.

In the invention which concerns on Claim 3, an outer cable support part is a substantially U-shaped hole formed in an outer cylinder holding | suppressing member in the form by which one end is open | released, and the outer cable stopped by this substantially U-shaped hole is substantially U-shaped. The key cylinder cover is provided with a wall that prevents it from coming out of the hole.
Since the outer cable can be fitted from the open end of the substantially U-shaped hole, the man-hour for attaching the outer cable is reduced. In addition, there is no fear that the outer cable will come out of the substantially U-shaped hole by the key cylinder cover.

In the invention according to claim 4, the key cylinder cover is formed by plastic deformation of a single steel plate. A three-dimensional key cylinder cover can be obtained by press forming a single steel plate. Since it is made of steel, the rigidity of the key cylinder cover is great.
In addition, steel sheets are inexpensive and press forming is performed in a short time. As a result, a rigid key cylinder cover can be manufactured at low cost.

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the vehicle 10 is a scooter type vehicle including front and rear wheels 12 that are steered by a handle 11 and rear wheels 14 that are supported by a power unit 13.
The driver sits on the front half of the seat 15 called a tandem seat, puts his foot on the step 16, and operates the handle 11. The passenger sits on the rear half of the seat 15 while grasping the grab rail 17 disposed behind the seat 15.

The vehicle body mainly including the vehicle body frame is covered with a vehicle body cover 20.
The vehicle body cover 20 includes, for example, a front cover 21 below the handle 11, an under cover 22 below the step 16, and a side cover 23 below the seat 15 and covering the side of the vehicle body.
The side cover 23 is divided in this example, and is disposed on the vehicle rear side of the side upper cover 24 disposed along the seat 15, the side lower cover 25 disposed below the side upper cover 24, and the side upper cover 24. The side rear cover 26 is arranged.

A luggage box is disposed under the sheet 15 as an opening / closing member. The luggage box will be described with reference to FIG.
FIG. 2 is a plan view of the rear portion of the vehicle with the seat removed. When the seat is opened, a luggage box 27 appears. The luggage box 27 is a resin molded product including a container case 28 that can store a helmet and the like, and a horizontal bulge portion 29 that protrudes from the container case 28 toward the rear of the vehicle.

  The horizontal bulge portion 29 is provided with a circular opening 32 through which the oil filler cap 31 is passed at the rear, and a rectangular opening 33 through which the U-shaped metal fitting (FIG. 9, reference numeral 92) attached to the seat is passed through the front (near the container case 28). Is provided. The luggage box 27 is fastened to the vehicle body frame with two screws 34 and 34 at least at the front portion of the horizontal bulging portion 29 (the fastening structure will be described later).

When the two screws 34, 34, etc. are removed, the luggage box 27 can be removed to the drawing front side.
Then, as shown in FIG. 3, the fuel tank 36 provided with the fuel pump 35 appears. The fuel tank 36 is a sealed container in which the upper half of the tank is overlapped with the lower half of the tank and the flange 37 is welded to be integrated.
A flange 37 is placed on a cross member 38, which is an element of the vehicle body frame, and a lock mechanism 80 represented by a seat catcher (detailed structure will be described with reference to FIG. 9) is placed on the flange 37. 37, bolts 41 and 41 are passed from above, and these bolts 41 and 41 are fastened to the cross member 38 side.

  That is, the fuel tank 36 and the lock mechanism 80 are fastened to the cross member 38 with the bolts 41 and 41. Co-tightening can reduce the number of bolts and reduce the number of bolt tightening steps.

  As shown in FIG. 4, the cross member 38 extends from the seat rail 42, and a bracket 43 that supports the lock mechanism 80 is provided at the center. A columnar stay 44 is extended upward from the cross member 38 at a portion between the bracket 43 and the seat rail 42.

The upper side of the side upper cover 24 is a substantially horizontal portion 46, and an inclined portion 47 extends outward from the substantially horizontal portion 46 in the vehicle width direction, and a vertical wall portion 48 is lowered from the inclined portion 47. That is, the seat rail 42 is surrounded by the substantially horizontal portion 46, the inclined portion 47, and the vertical wall portion 48.
A tongue piece 49 extends from the substantially horizontal portion 46 to the center of the vehicle body, and the tongue piece 49 is placed on the columnar stay 44. Further, a horizontal bulging portion (FIG. 2, reference numeral 26) of the luggage box is placed on the tongue piece 49, and the horizontal bulging portion and the tongue piece 49 are fastened together with screws 34. That is, the side upper cover 24 and the luggage box are fastened together with the screws 34.

FIG. 5 is a cross-sectional view of the main part of FIG. 4. The lock-unlocking mechanism 50 includes a flange 51 at one end, and an outer cylinder 53 including a circumferential groove 52 having a smaller diameter than the general part along the flange 51. The cylinder 57 includes a key hole 55 that is rotatably attached to the outer cylinder 53 and has a key hole 55 into which the key 54 is inserted.
One end of the operation cable 60 composed of the inner cable 58 and the outer cable 59 (more precisely, one end of the inner cable 58) is stopped on the arm 56.

A cylinder mounting hole 61 through which the outer cylinder 53 is passed is provided in the inclined portion 47 of the side upper cover 24. When the outer cylinder 53 is passed through the cylinder mounting hole 61, the flange 51 hits the outer surface of the inclined portion 47 and stops. The outer cylinder holding member 62 is attached to the outer cylinder 53 from the vehicle body center side. An urging member 63 such as a spring washer is fitted into the circumferential groove 52, and the outer cylinder holding member 62 is pressed against the inner surface of the inclined portion 47 by the urging member 63.
The inclined portion 47 is strongly sandwiched between the flange portion 51 and the outer cylinder holding member 62. As a result, the lock unlocking mechanism 50 is fixed to the vehicle body cover (side upper cover 24).

  The outer cylinder holding member 62 includes a main body portion 64 that contacts the inner surface of the inclined portion 47, and an extension portion 65 that extends from the edge of the main body portion 64 toward the center of the vehicle body. If only the lock / unlock mechanism 50 is fixed, only the main body 64 may be used.

In this example, the extension portion 65 is intentionally provided, and the outer cable support portion 66 is provided at the tip of the extension portion 65. One end of the outer cable 59 is fixed to the outer cable support portion 66.
When the cylinder 57 is rotated with the key 54, the arm 56 swings and the inner cable 58 is pulled. The outer cable 59 is a sheath tube that protects the inner cable 58 and is fixed to the outer cable support portion 66 and does not move in the axial direction.

  As is clear from the figure, the lock unlocking mechanism 50 is fixed to the vehicle body cover by sandwiching the vehicle body cover (inclined portion 47) between the outer cylinder holding member 62 and the flange portion 51. No bracket is required to connect 50 to the body frame.

  In addition, in order to fix the lock / unlock mechanism 50 to the vehicle body cover, the lock / unlock mechanism 50 is pre-attached to the vehicle body cover, and one end of the operation cable 60 is connected to the lock / unlock mechanism 50. The vehicle assembly line can be used, and the vehicle assembly line can be simplified.

  Furthermore, one end of the operation cable 60 can be supported by the outer cylinder holding member 62. In general, an operation cable is fixed to a vehicle body frame or a vehicle body cover via a locking member such as a hook. According to this example, since one end of the operation cable 60 is stopped using the outer cylinder holding member 62, it is not necessary to prepare a separate locking member.

  As shown in FIG. 6, a lock / unlock mechanism 50 is fixed to the side upper cover 24. And the main-body part 64 of the outer cylinder holding member 62 exhibits a substantially rectangular shape. Anti-rotation protrusions 67 and 68 are provided on the inner surface of the inclined portion 47, and the main body 64 is disposed along the anti-rotation protrusions 67 and 68. As a result, the main body portion 64, that is, the outer cylinder holding member 62 can be prevented from idling due to the contact with the anti-rotation protrusions 67 and 68.

  Further, the columnar screw seats 69 and 69 are extended from the inner surface of the inclined portion 47 toward the center of the vehicle body so as to sandwich the lock unlocking mechanism 50. The key cylinder cover 70 is applied to these columnar screw seats 69 and 69 and fixed with the small screws 71 and 71.

As a result, as shown in FIG. 7, most of the lock / unlock mechanism 50 was enclosed by the key cylinder cover 70. Even if a minus driver is inserted from the upper edge of the side upper cover 24, the minus driver is blocked by the key cylinder cover 70 and does not reach the lock unlocking mechanism 50.
That is, the key cylinder cover 70 serves as a protector of the lock / unlock mechanism 50, and external force is applied to the key cylinder cover 70 but does not reach the lock / unlock mechanism 50. There is no need to make the lock / unlock mechanism 50 robust, and the lock / unlock mechanism 50 can be easily reduced in size and weight.

  The side rear cover 26 is applied to the rear edge of the side upper cover 24, and both the covers 24 and 26 are connected by screws 72. Further, the upper edge of the side lower cover 25 is applied to the lower edge of the side upper cover 24, and both the covers 24, 25 are connected by screws 73. The ear piece 74 is extended from the lower edge of the side lower cover 25.

  As shown in FIG. 8, an ear piece 74 is fixed to a pillion bracket 75 which is a part of the vehicle body frame by a bolt 76. The side lower cover 25 can be fixed to the vehicle body side by skillfully utilizing the pillion bracket 75 prepared for another purpose. The ear piece 74 and the bolt 76 are covered with an under cover (FIG. 1, reference numeral 22). As a result, the appearance is kept good.

The operation of the lock mechanism and the lock / unlock mechanism having the above configuration will be described below.
As shown in FIG. 9, the lock mechanism 80 includes a base 81 fixed to the bracket 43 with bolts 41, 41, a wall portion 82 raised from the base 81, and formed on the wall portion 82 and opened upward. A U groove 83, a lock claw 85 rotatably attached to the wall portion 82 via a pin 84, an arm portion 86 extending below the lock claw 85, and the wall portion 82 so as to mesh with the arm portion 86. A cam 88 that is rotatably attached by a pin 87, a cable coupling portion 89 that extends from the cam 88 and stops the other end of the inner cable 58, and a lock claw 85 rotate to the unlock side (counterclockwise in the figure). The cam 88 includes a cam 88 and a tension spring 91 that is passed to the arm portion 86 so that the cam 88 rotates clockwise in the drawing.

  In the figure, the U-shaped metal fitting 92 on the seat side enters the U groove 83 and cannot be raised by the lock claw 85. Since the cam 88 holds the arm portion 86, there is no concern that the arm portion 86 and the lock claw 85 rotate counterclockwise in the figure. This state is a locked state.

  When the inner cable 58 is pulled by the lock / unlock mechanism 50, the cam 88 rotates counterclockwise in the figure and comes off the arm portion 86. Then, the arm part 86 and the lock claw 85 pulled by the tension spring 91 rotate counterclockwise in the figure. As a result, the lock claw 85 is separated from the U groove 83, and the U-shaped fitting 92 can be raised. This state is called a lock / unlock state.

In the figure, a key cylinder cover 70 is a three-dimensional object obtained by plastic processing of a single steel plate.
The structure of the key cylinder cover 70 will be described in detail with reference to FIGS.

  As shown in FIG. 10, the key cylinder cover 70 has a groove (consisting of a bottom 93, a first wall 94 and a second wall rising from the bottom 93) through which the operation cable 60 passes. The first wall 94 and the second wall 95 provided on the columnar stay 44 side with respect to the first wall 94 exert the following actions.

Although the outer cable 59 does not move in the axial direction, the outer cable 59 swings in the direction perpendicular to the axis when the inner cable 58 moves.
The second wall 95 exhibits a guide action, and prevents the outer cable 59 from contacting the columnar stay 44.

  As shown in FIG. 11, the outer cable support part 66 is a substantially U-shaped hole formed in the extension part 65 in a form in which one end is opened, and the outer cable 59 fixed to the substantially U-shaped hole is substantially U-shaped. A first wall 94 is provided on the key cylinder cover 70 to prevent it from coming out of the hole.

  Since the outer cable 59 can be fitted from the open end of the substantially U-shaped hole, the man-hour for attaching the outer cable is reduced. In addition, the first wall 94 of the key cylinder cover 70 eliminates the concern that the outer cable 59 will come out of the substantially U-shaped hole.

  In addition, an engagement portion 96 into which the tip of the extension portion 65 of the outer cylinder holding member can be inserted is integrally formed on the bottom 93 of the key cylinder cover 70. The engaging portion 96 is preferably an elongated hole (slit).

Since the outer cable support part 66 is provided, the extension part 65 of the outer cylinder holding member extends to the outer cable 59 like a cantilever beam starting from the outer cylinder (reference numeral 53 in FIG. 10). In the cantilever beam, the bending and deflection of the tip increase, so that it is necessary to increase the rigidity as a whole, and the weight of the outer cylinder holding member 62 is increased.
In this regard, in this embodiment, the distal end of the extension portion 65 of the outer cylinder holding member is stopped by the key cylinder cover 70. Since both ends of the outer cylinder holding member 62 are supported, bending and vibration are reduced even if the outer cylinder holding member 62 is thin. As a result, the outer cylinder holding member 62 can be reduced in size and weight.

  As shown in FIG. 10, the key cylinder cover 70 is a three-dimensional object having a bottom 93, a first wall 94, and a second wall 95, and is a resin molded product. It can also be manufactured by plastic working.

  The mounting structure of the unlocking mechanism of the present invention is suitable for a scooter type vehicle, but can also be applied to other two-wheeled vehicles, three-wheeled vehicles, and four-wheeled vehicles.

Further, the opening / closing member may be a lid for an accessory case in addition to the sheet.
In the embodiment, the side of the lock / unlock mechanism is a side upper cover, but it may be a side rear cover or a front cover, or any body cover.

  The lock unlocking mechanism mounting structure of the present invention is suitable for a scooter type vehicle.
