1. Field of the Invention
The present invention relates to a front portion structure of a vehicle equipped with a light device provided on a front cowl covering a vehicle body and to an improvement in a key cylinder arrangement structure for a vehicle provided with a key cylinder that mechanically enables a start or operation of the vehicle when an electronic key system does not establish authentication.
2. Description of Background Art
A front portion structure of a vehicle is known wherein a front cowl covering a vehicle body is provided on a front portion of the vehicle body that is equipped with a light device and a leg shield having a storage portion for storing an article therein is provided between the light device and a seat on which a rider sits. See, for example, Japanese Patent Laid-open No. 2005-112313 (FIGS. 14 and 15).
In FIG. 14 of Japanese Patent Laid-open No. 2005-112313, a first article storage portion 191 for storing an article therein is disposed on the left of the leg shield 158. A second article storage portion 192 is disposed on the right of the leg shield 158. A storage case 193 is detachably provided in the first article storage portion 191 disposed on the left side. An end wall 197a of the first article storage portion 191 is provided with a maintenance window 201, which is covered by a detachable lid 202.
In
In addition, the second article storage portion 192 disposed on the right of the vehicle is not provided with an opening. When maintenance such as the replacement of a right-hand bulb is performed, it is necessary to remove a whole storage recess portion 214 attached to the leg shield 158.
Even if the end wall of the second article storage portion 192 on the right side of the vehicle is provided with an opening, the position of the bulb axis of a lamp device may not be aligned with the position of the maintenance opening. Thus, in such a case, since an individual's hand cannot reach a bulb, it is sometimes difficult to perform maintenance including bulb replacement for the front portion of the vehicle.
In addition, a vehicle is known wherein an electronic key system that enables a start or operation of a vehicle when authentication is established between a portable transmitter and a receiver and with a leg shield for shielding the front of the legs of a rider sitting on a seat and the leg shield is provided with a key cylinder that enables a start or operation of the vehicle when the electronic key system does not establish authentication. See, for example, Japanese Patent Laid-open No. 2005-112313 (FIG. 18).
In
A key cylinder lock 236 having a key hole 238 is disposed at the storage recess portion 214 in such a manner that the key hole 238 faces the inner lateral surface of the storage recess portion 214.
As described above, the key cylinder lock 236 is disposed on the inner lateral surface of the storage recess portion 214 to provide a structure hard to be tampered. However, it is difficult to identify the key hole of the key cylinder with the rider mounting on the vehicle. There is room for improvement.
It is an object of an embodiment of the present invention to provide a vehicle front portion structure having a storage portion that facilitates maintenance for a vehicle front portion.
According to an embodiment of the present invention, a front portion structure of a vehicle includes a front cowl provided at a front portion of a vehicle body to cover the vehicle body with a light device having at least a portion that is provided at the front cowl so as protruding rearward. A leg shield is disposed between the light device and a seat on which a rider sits and includes a storage portion for storing an article therein. The storage portion includes a bottom portion extending in the longitudinal direction of the vehicle body with left and right walls extending upwardly from the left and right sides, respectively, of the bottom portion. A ceiling portion connects together the left and right walls with a back wall which closes the respective backs of the bottom portion, left and right walls and the ceiling portion. A bulb axis of the light device is disposed near the back wall as viewed from the rear of the vehicle body with the storage portion being provided with a maintenance opening spanned among the back wall, at least one lateral wall continuous with the back wall, and the bottom portion or ceiling portion continuous with the back wall. A lid body detachably covers the maintenance opening forming the maintenance opening being used to maintain the bulb.
According to an embodiment of the present invention, the bulb axis of the light device is disposed outside the back wall as viewed from the rear of the vehicle and the maintenance opening is provided to extend from the back wall at least to a lateral wall closer to the bulb axis of the light device.
According to an embodiment of the present invention, the storage portion is provided with a storage case as a stuff box in an openable and closable manner with the storage portion serving as a drawer.
According to an embodiment of the present invention, the light device is a pair of light devices, one light device and the other light device, spaced apart from each other on the left and right of the vehicle, the opening is disposed near a bulb axis of the one light device of the light devices. A second storage portion that is larger in size than the back wall is disposed near the other light device of the light devices with the second storage portion being provided with a second maintenance opening.
According to an embodiment of the present invention, the lid body is provided at one end with an engaging claw to be engaged with a hole portion of the storage portion and at the other end with an engaging portion to be engaged with the storage portion. The engaging claw is engaged with the hole portion and the engaging portion is engaged with the storage portion.
According to an embodiment of the present invention, the bulb axis of the light device is disposed near the back wall as viewed from the rear of the vehicle body and the storage portion is provided with the maintenance opening spanned among the back wall, at least one lateral wall continuous with the back wall, and the bottom portion or ceiling portion continuous with the back wall and is used to maintain the bulb. Thus, the maintenance opening can largely be ensured without being influenced by the size of the storage portion composed of the back portion, the lateral portions, the bottom portion and the ceiling portion.
If the maintenance opening is enlarged, the bulb of the light device can easily be replaced by removing the lid body, by passing a hand through the maintenance opening and by reaching out the hand for the bulb of the light device. Thus, the maintenance such as replacement of the bulb or the like can be enabled without the removal of the leg shield, that is, the maintenance for the vehicle front portion including the light device can easily be performed.
In addition, since the maintenance opening is increased in size, design restrictions can be reduced. For example, it becomes not necessary to otherwise determine the position of the storage portion, taking into account the maintenance performance for the bulb of the light device. Since the design restrictions are reduced, the flexibility of vehicle design can be increased.
According to an embodiment of the present invention, since the maintenance opening is provided to extend from the back wall at least to the lateral wall closer to the bulb axis of the light device, the area of the opening is expanded by the extension to the lateral wall. Thus, when the lid body is removed and a hand is passed through the maintenance opening, even if the central position of the bulb of the light device is offset from the position of the opening, maintenance work for the bulb can easily be performed by reaching out a hand for the bulb of the light device.
According to an embodiment of the present invention, when the maintenance opening is continuously formed to extend from the back wall to the lateral wall, the storage case is formed as a drawer. Thus, the drawer can close the maintenance opening and the lid body. Since the drawer is provided in the storage portion, the maintenance opening and lid body can be made inconspicuous from the outside of the vehicle, which can prevent the external appearance of the vehicle from being impaired.
According to an embodiment of the present invention, the maintenance opening and the second maintenance opening are provided near the one light device and the other light device, respectively; therefore, both the bulbs of the light devices can be replaced by passing a hand through the associated maintenance openings. Since the bulb can be replaced by passing the hand through the maintenance opening disposed near the bulb, the maintenance performance for the bulb can fiber be enhanced.
According to an embodiment of the present invention, the lid body is provided at one end with the engaging claw to be engaged with the hole portion of the storage portion and at the other side with the engaging portion to be engaged with the storage portion, the engaging claw is engaged with the hole portion and the engaging portion is engaged with the storage portion.
Since the lid body is integrally formed with the engaging claw and the engaging portion at one end and the other end, respectively, it can simply be molded.
In addition, since the number of engaging positions using the engaging portion is one, the number of parts for the engaging portion can be reduced. Since the lid body can simply be molded and the number of parts for the engaging portion is reduced, the cost of parts for the lid body can be suppressed.
It is an object of an embodiment of the present invention to provide a key cylinder arrangement structure for a vehicle that can significantly enhance operability of a key cylinder while preventing tampering, theft and the like.
According to an embodiment of the present invention, a key cylinder arrangement structure for a vehicle including an electronic key system which enables a start or operation of the vehicle only when authentification is established between a portable transmitter taken along by a rider and a receiver installed in the vehicle. A leg shield which covers the front of the legs of the rider sitting on a seat and has an upper portion including a stuff box is provided together with a key cylinder which mechanically enables a start or operation of the vehicle by insertion-operating a key adaptable when the electric key system does not establish authentification. The key cylinder is disposed so that a key cylinder axis is parallel to the longitudinal axis of the vehicle and is provided at the leg shield so as to face the rider sitting on the seat. The stuff box is provided with an appearance member forming a design surface of the leg shield with the key cylinder being covered by the appearance member when the stuff box is closed.
According to an embodiment of the present invention, the stuff box is a drawer having an opening at an upper surface thereof and the key cylinder is disposed below a bottom portion of the drawer.
According to an embodiment of the present invention, the stuff box is a drawer and the appearance member is a component constituting a knob portion on which a hand of the rider is put when the drawer is opened.
According to an embodiment of the present invention, the stuff box is openable in a range where the stuff box does not come into contact with the leg of the rider sitting on the seat.
According to an embodiment of the present invention, the vehicle is a lower floor type vehicle including left and right foot placing portions on which the feet of the rider are placed when the rider mounts on the vehicle and a tunnel portion which connects the left and right foot placing portions and protrudes upward, the leg shield is configured to connect with the foot placing portion and with the tunnel portion, and the key cylinder is disposed at a position close to the tunnel portion and to the center of a vehicle body.
According to an embodiment of the present invention, since the key cylinder is disposed so that a key cylinder axis is parallel to the longitudinal axis of the vehicle, the direction of the key cylinder axis can be made approximately the same as that of the key inserted into the key cylinder by the rider. Thus, it becomes easy to insert the key into the key cylinder, which can significantly enhance the operability of the key cylinder.
In addition, since the key cylinder is covered by the appearance member when the stuff box is closed, it is possible to make the key cylinder less-visible from the third party, thereby preventing tampering or theft. In short, the present invention can maintain crime-prevention while enhancing the operability of the key cylinder.
According to an embodiment of the present invention, since the staff box is a drawer having an opening at an upper surface thereof and the key cylinder is disposed below a bottom portion of the drawer, the key cylinder is disposed at a position further less-visible from the third party. Since the position of the key cylinder is further less-visible from the third party, tampering, theft or the like can further be prevented.
According to an embodiment of the present invention, since the stuff box is a drawer and the drawer and the knob portion are made of different components, the respective shapes of the stuff box and appearance member can freely be set. Since the flexibility of setting the shapes is increased, the external appearance of the appearance member can be enhanced while sufficiently ensuring the capacity of the stuff box.
According to an embodiment of the present invention, the stuff box is openable in a range where it does not come into contact with the leg of the rider sitting on the seat. Even if the key cylinder is intended to be operated, for example, by inserting a long tool or the like into the key cylinder, since the tool interferes with the appearance member of the stuff box, it becomes difficult to insert the tool or the like into the key cylinder. In short, tampering or the like can further be prevented by limiting the opening stroke of the stuff box. In addition, since the stuff box is made hard to hit the legs of the rider, easiness of mount and dismount is not damaged.
According to an embodiment of the present invention, the key cylinder is disposed close to the tunnel portion protruding upward and to the center of the vehicle body. When the key cylinder is intended to be operated, for example, by inserting a long tool or the like into the key cylinder, since the tool interferes with the tunnel portion, it becomes difficult to insert the tool into the key cylinder. In other words, tampering or the like can further be prevented by disposing the key cylinder at a position close to the tunnel portion.
