Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote lock operating device for a light vehicle having no cabin. In the present invention, the "light vehicle having no cabin" may be a saddle-ride type or a perched-type two-wheeled vehicle, a three-wheeled vehicle or a four-wheeled vehicle, and may or may not have a motor. For example, motorcycles include motorcycles, scooters, bicycles, and the like.

[0002]

2. Description of the Related Art In conventional light vehicles such as motorcycles and scooters, various lock mechanisms for preventing theft and mischief, such as a main stand lock mechanism, a handle lock mechanism, and a seat lock mechanism, are provided at appropriate positions in the vehicle body. These lock mechanisms are arbitrarily locked and operated by the occupant directly operating keys on the lock operation section provided on the vehicle body side.
It can be unlocked.

[0003] On the other hand, in recent four-wheeled vehicles, there has been widely known a type in which a door lock mechanism can be locked and unlocked without a key using a remote lock operation device using an infrared signal.

[0004]

Therefore, it is conceivable that the lock mechanism in a light vehicle as described above can be locked / unlocked without a key by a remote lock operation device using an infrared signal.

In this case, unlike the four-wheeled vehicle, the light vehicle does not have a sturdy cabin whose periphery is widely surrounded by a roof, side doors, etc., and the entire exterior of the vehicle body including the steering wheel and its surroundings is external. Widely exposed to. Therefore, in providing the infrared receiving section on the outer surface of such a vehicle body, it is desirable that the infrared receiving section is not easily damaged due to collision with another object.

The directivity required of the infrared receiver in the above-described light vehicle generally takes a rearward direction from the front-rear position of the left and right handle grips of the vehicle as shown in FIG. As seen, it is in a range of 45 degrees left and right with respect to the longitudinal center line of the vehicle body. Therefore, the mounting position of the infrared receiving unit is such that the receiving unit can cover at least the above directivity range without being affected by the seat or the rear vehicle body. It is desirable to set the position.

Further, when the infrared receiving section is exposed to direct sunlight in the daytime, a noise signal from sunlight is mixed in a signal received by the receiving section, and the signal-to-noise ratio (SN ratio) of the receiving section is correspondingly increased. And the reliability of communication with the infrared transmitter may be reduced. Therefore, when installing the infrared receiving unit, it is desirable to make it hard to be exposed to direct sunlight during the day.

[0008] The present invention has been proposed in view of the above,
An object of the present invention is to provide a remote lock operation device for a light vehicle that has a simple structure and satisfies the above-mentioned requirements.

[0009]

In order to achieve the above object, according to the present invention, a bar handle for steering a front wheel and a handle cover for covering a central portion of the bar handle are provided on the front side and above the seat. A remote lock operation device for a light vehicle without a cabin, comprising: a portable infrared transmitter, an infrared receiver capable of receiving an infrared signal emitted by the transmitter, and a lock mechanism mounted on the vehicle body A lock actuator capable of locking / unlocking, and a control device for controlling the operation of the lock actuator based on the infrared signal received by the infrared receiving unit, wherein the infrared receiving unit is inclined rearward and downward of the handle cover. It is provided on the rear outer surface.

According to this feature, even if the light vehicle does not have a sturdy cabin surrounded by a roof or the like, the infrared receiver is provided on the rear outer surface of the handle cover which is hardly damaged due to collision with other objects. Since the infrared receiver is provided, the infrared receiver can be effectively protected from overturning and the like, and the running reliability can be improved. In addition, since the infrared receiver is disposed on the rear outer surface that is inclined rearward of the steering wheel cover, it is difficult for the infrared receiver to be exposed to direct sunlight during the day, thereby effectively lowering the SN ratio of the receiver. Being suppressed to
Communication reliability between the transmitting and receiving units is improved. In addition, since the handle cover is generally higher than the seat and the rear body, the infrared receiver is disposed on the rear outer surface of the handle cover, so that the directional range of the infrared receiver required in a light vehicle can be reduced. And can be easily covered without being affected by the rear vehicle body as much as possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below based on embodiments of the present invention illustrated in the accompanying drawings.

1 to 4 show an embodiment in which the present invention is applied to a scooter. FIG. 1 is a plan view of the scooter, FIG. 2 is a side view of the scooter, and FIG.
FIG. 4 is a perspective view of the handle of the scooter and its peripheral portion as viewed obliquely from the rear (a magnified view as viewed from the direction of arrow 3 in FIG. 2). FIG.

First, in FIGS. 1 and 2, the scooter V as a light vehicle is provided with a step ST for placing an occupant's foot between the front and rear wheels Wf and Wr.
A seat S on which an occupant sits is disposed above a rear body cover Fr made of metal or synthetic resin as a rear body rising from the rear end of T. This rear body cover F
A seat box (not shown) for storing luggage is provided in the seat r. The seat S can be opened and closed between a closed position and an open position where the seat S covers the open upper surface of the seat box. , Attached to the seat box or the like.

The scooter V has a bar handle H for steering the front wheel Wf via the steering shaft 11. The steering shaft 11 is rotatably supported by a head pipe of a front body frame (not shown), and the inside of a front body cover Ff made of metal or synthetic resin as a front body, that is, the rear side is vertically and rearward. It extends in a tilted posture. The lower portion of the steering shaft 11 is formed in a bifurcated fork shape to rotatably support the front wheel Wf. The upper end of the steering shaft 11 is connected to the center of the bar handle H, so that the handle H and the steering shaft 11 rotate integrally in response to the operation of the handle.

The central portion of the bar handle H and the upper end of the steering shaft 11 are covered with a synthetic resin or metal T-shaped handle cover Hc which rotates integrally with the handle H. From both left and right ends of the handle cover Hc, the left and right handle grips H at both ends of the bar handle H are provided.
g respectively extend. The rear outer surface 20 of the handle cover Hc is inclined rearward and downward, and an infrared receiver R described later is provided on the rear outer surface 20 of the cover Hc that is inclined rearward.

The rear side of the lower part of the steering shaft 11 below the handle cover Hc is covered with an inner cover I made of metal or synthetic resin rising integrally from the front end of the step ST. The inner cover I is detachably connected to the back side of the front body cover Ff, and a vehicle space through which the steering shaft 11 passes is formed between the back side of the cover Ff and the inner cover I.

In the proper position of the scooter V in the vehicle body, a handle lock mechanism Lh for restricting rotation of the handle H during parking, and a main stand Mt rotatable between a standing position and a horizontal storage position are locked at the standing position. And a seat lock mechanism Ls for locking the seat S at a closed position covering the open upper surface of the seat box. These lock mechanisms Lh, Lm,
Since the structure of Ls is conventionally known, a detailed description of the structure is omitted.

Operation wires Wh, Wm, Ws extend from the lock mechanisms Lh, Lm, Ls, respectively, and lock the lock mechanisms Lh, Lm, Ls via these operation wires Wh, Wm, Ws. One common electric lock actuator 1 for unlocking is provided at an appropriate position in the vehicle body. The lock actuator 1 constitutes a part of the remote lock operation device A of the present invention, and performs a lock operation / unlock in response to a command signal from an electronic control circuit C as a control device disposed at an appropriate position in a vehicle body. A lock operation is performed to lock / unlock each lock mechanism Lh, Lm, Ls without a key.

The remote lock operation device A can receive a small infrared transmitter T which can be carried by an occupant, and an infrared signal emitted by the transmitter T, in addition to the lock actuator 1 and the electronic control circuit C. The handle cover Hc
And an infrared receiver R installed on the rear outer surface 20 inclined backward. The transmitter T is provided with an operation switch 2 for inputting operation of lock / unlock, and has a specific ID. A signal transmission unit (not shown) that can transmit an infrared signal corresponding to the code in response to an operation input to the switch 2 is built in. The structure of such an infrared transmitter is well known.

The electronic control circuit C has a signal determining unit C1 including a CPU and a memory.
Indicates whether the infrared signal received by the infrared receiver R is correct, that is, a specific ID in which the ID code of the received signal is stored in advance.
ID collating means for collating and judging whether the code coincides with the code, and an operation command to the lock actuator 1 in response to the collating means judging that the received signal is a regular infrared signal (the ID code coincides). Command signal output means for outputting a signal.

The electronic control circuit C has a first energizing circuit 3 for supplying power of the battery B thereto, and a relay circuit 4 having a main switch Sw and a main relay Re.
This relay circuit 4 opens and closes a second energizing circuit 5 connecting the battery B and each of the on-board electrical systems (including an engine starting circuit) to control energization of each of the electrical systems. .

Next, the operation of the above embodiment will be described.

Now, when the scooter V is parked and the lock actuator 1 is in the lock operating state, the handle lock mechanism Lh and the stand lock mechanism Lm
It is assumed that all the seat lock mechanisms Ls are held in the locked state.

In this state, an infrared signal is emitted from the infrared transmitter T toward the infrared receiver R, and when the infrared signal is received by the infrared receiver R, the signal determination unit C of the electronic control circuit C
1, the received signal is correct or not, that is, the I
It is determined whether or not the D code matches a specific ID code stored in advance. If it is determined that the signal is a regular infrared signal (the ID code matches), an operation command signal is sent to the lock actuator 1. Is output to switch the actuator 1 from the locked state to the unlocked state, whereby the handle lock mechanism Lh, the stand lock mechanism Lm, and the seat lock mechanism Ls are unlocked all at once. At the same time, the electronic control circuit C sets the main relay Re to the energized state.

Then, when the main switch Sw is switched from off to on, the main relay Re can be turned on, so that power can be supplied to each of the electrical systems including the engine starting circuit. Therefore, in this state, if a start switch (not shown) is turned on, power is supplied to the engine start circuit, and the engine can be started. When the start is completed, the scooter V becomes ready to run.

In order to stop the running engine, the main switch Sw is switched from on to off. As a result, the power supply to the electric system of the engine is cut off, and the engine stops. When the infrared signal is transmitted again from the infrared transmitter T to the infrared receiver R from this state, the signal determination unit C1 of the electronic control circuit C checks the correctness of the received signal as described above. ,
If it is determined that the signal is a regular infrared signal, an operation command signal is output to the lock actuator 1 to switch the actuator 1 from the unlocked state to the locked state, and thus the handle lock mechanism Lh and the stand lock mechanism Lm and the seat lock mechanism Ls are simultaneously locked. At the same time, the electronic control circuit C sets the main relay Re to the non-energized state, so that even if the main switch Sw is turned on, the main relay Re does not turn on.

Although the scooter V does not have a sturdy cabin surrounded by a roof or the like, the infrared receiver R of the remote lock operation device A has a handle cover that is less susceptible to damage due to collision with other objects. Hc rear outer surface 2
Since it is provided at 0, the infrared receiver R can be effectively protected from overturning and the like, and the running reliability is enhanced. Moreover, the infrared receiver R is provided with a handle cover Hc.
Since the infrared receiver R is disposed on the rear outer surface 20 inclined backward, it is difficult for the infrared receiver R to be exposed to direct sunlight in the daytime, whereby deterioration of the S / N ratio of the receiver R is effectively suppressed. Communication reliability between the transmitting and receiving units is improved.

The directivity required of the infrared receiving unit R in the scooter V generally takes a rearward direction from the front-rear position of the left and right handle grips Hg of the vehicle, as shown in FIG. Is considered to be in a range of 45 degrees left and right with respect to the vertical center line of the vehicle body, the mounting position of the infrared receiver R is set so that the receiver is not affected by the seat S and the rear vehicle body. It is desirable that the infrared receiver R be set at a position where the cover can be covered. However, as in the present embodiment, the infrared receiver R is provided on the rear outer surface 20 of the handle cover Hc located on the front side and above the seat S and the rear body Fr. By doing so, it is possible to improve the reception performance by minimizing the reception obstacle behind the reception unit R and thereby to reduce the directivity range of the infrared reception unit required for the scooter V. Readily enables the cover without being influenced by the seat S or the rear body Fr.

Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various small design changes can be made. For example, in the above-described embodiment, a plurality of lock mechanisms Lw, Lh, and Ls are locked and unlocked simultaneously by one common lock actuator 1. However, in the present invention, a plurality of lock mechanisms Lw, Lh, and Ls are locked. Lh and Ls may be locked and unlocked by dedicated lock actuators.

[0030]

As described above, according to the present invention, even if a light vehicle does not have a sturdy cabin surrounded by a roof or the like, the infrared receiver of the remote lock operation device can be used to make contact with other objects. Because it is provided on the rear outer surface of the handle cover, which is less likely to be damaged, the infrared receiver can be effectively protected from overturning, etc., and running reliability can be improved. Since it is difficult to receive direct sunlight during the day, the deterioration of the S / N ratio of the receiving unit is effectively suppressed, and the communication reliability between the transmitting and receiving units can be improved. In addition, since the handle cover is generally located higher than the seat and the rear body, the infrared receiver is disposed on the rear outer surface of the handle cover, so that the directional range of the infrared receiver required in a light vehicle can be reduced. It is possible to cover easily without being affected by the rear body as much as possible.
