[0002]
[Prior art]
In recent four-wheeled vehicles, a door lock mechanism that can be locked and unlocked without a key by a remote control lock operation system using an infrared signal is widely used.
[0003]
On the other hand, in conventional light vehicles such as motorcycles and scooters, there are various mechanical lock mechanisms (for example, a main stand lock mechanism, a handle lock mechanism, etc.) that make the vehicle mechanically impossible to prevent theft or mischief. These mechanical lock mechanisms are provided at appropriate positions in the vehicle body, and can be arbitrarily locked / unlocked by a passenger operating keys directly on a lock operation unit provided on the vehicle body side.
[0004]
[Problems to be solved by the invention]
Therefore, in order to enable the mechanical lock mechanism as described above to be unlocked without a key by a remote control lock operation system using an infrared signal, for example, the transmitter / receiver and the mechanical lock mechanism are driven with respect to the mechanical lock mechanism. It is conceivable to configure a remote control lock operation system for a mechanical lock mechanism by combining a lock actuator and a control device.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below based on the embodiments of the present invention illustrated in the accompanying drawings.
[0013]
1 is an overall side view of a scooter according to an embodiment of the present invention, FIG. 2 is a schematic block diagram of the first embodiment, FIG. 3 is a schematic block diagram of the second embodiment, and FIG. 4 is a third embodiment. FIG. 5 is a schematic block diagram of the fourth embodiment.
[0014]
First, in FIG. 1 and FIG. 2, the scooter V as a vehicle is provided with a step ST in which the occupant's feet are placed between the front wheels Wf and Wr, and as a rear body that rises from the rear end of the step ST. A seat S is disposed on the rear body cover Fr.
[0015]
Further, the steering shaft 1 of the scooter V is rotatably supported by a head pipe of a metal body frame (not shown), and moves up and down inside the metal or synthetic resin front body cover Ff as a front body. In addition, it extends in a backward tilting posture. A front fork 2 that supports the front wheel Wf is coupled to a lower end portion of the steering shaft 1, and an upper end portion of the steering shaft 1 is coupled to a central portion of the bar handle H. Thus, the turning operation of the bar handle H is transmitted to the steering shaft 1 and the front fork 2, and the front wheel Wf is steered.
[0016]
The central portion of the bar handle H and the upper end portion of the steering shaft 1 are nicely covered with a synthetic resin or metal handle cover Hc that rotates integrally therewith, and from both left and right end portions of the handle cover Hc. The left and right handle grips Hg at both ends of the bar handle H extend.
[0017]
The rear side of the steering shaft 1 below the handle cover Hc is covered with an inner cover I made of metal or synthetic resin that rises integrally from the front end of step ST. The inner cover I is detachably coupled to the back side of the front body cover Ff, and a vehicle body space 3 through which the steering shaft 1 passes is formed between the back side of the cover Ff and the inner cover I.
[0018]
In the vehicle body space 3, a handle lock mechanism L for locking the rotation of the steering shaft 1 (and hence the handle H) at the time of parking and a main part of a remote control lock operation system for operating this by remote control are integrated. A unitized lock module M is provided. Next, the configuration of the lock module M will be described with reference to FIG.
[0019]
The lock module M has a box-shaped module housing 4. In this module housing 4, an infrared receiver R capable of receiving an infrared signal transmitted from an infrared transmitter T carried by a passenger, and a handle lock mechanism L as a mechanical lock mechanism that mechanically disables traveling of the vehicle. A lock actuator A that is interlocked and connected to the handle lock mechanism L to lock / unlock the lock actuator A, and whether or not the received signal of the receiver R is correct. A control device C that controls the operation is provided together with wiring portions 5 and 6 that connect the lock actuator A and the receiver R to the control device C, respectively.
[0020]
The module housing 4 includes a part of an energizing circuit 8 for energizing each on-vehicle electrical component 7 from the battery BA, a main relay 9 capable of opening and closing a part of the energizing circuit 8, and the main relay 9 And a main switch SW for turning on / off. The main switch SW is also connected to the lock actuator A. By turning on the switch SW, the lock actuator A can be operated to unlock the handle lock mechanism L regardless of the control device C. Yes.
[0021]
The module housing 4 is inserted into the vehicle body space 3 from the rear through an opening Ia formed in the rear end surface of the inner cover I on the front side of the rear end portion of the handle cover Hc, and is provided at a suitable position of a vehicle body frame (not shown), for example, It is fixed to the head pipe. In its fixed state, at least a portion of the surface 4r after the module housing 4 is exposed to the outside through the opening Ia of the inner cover I. On the rear surface 4r of the module housing 4, the signal receiving portion Ra of the receiver R is arranged so as to be able to receive signals from the rear.
[0022]
The handle lock mechanism L includes a lock case 10 fixed to the front end portion of the module housing 4 and a lock pin 11 that is driven by the lock actuator A and moves forward and backward from the lock case 10 toward the steering shaft 1. A locking hole 1a is formed in the peripheral wall of the steering shaft 1 corresponding to the lock pin 11, and the lock pin 11 is locked when the lock pin 11 is at a predetermined lock position where the lock pin 11 is advanced to the maximum. The steering shaft 1 is locked at a predetermined rotation position by engaging with the hole 1a, that is, the lock mechanism L is brought into a locked state. On the other hand, when the lock pin 11 is in the unlock position retracted by a predetermined amount from the lock position, the lock pin 11 is released from the locking hole 1a to allow the steering shaft 1 to freely rotate, that is, unlock the lock mechanism L. State.
[0023]
The module housing 4 is provided with a key cylinder (not shown) into which an ignition key can be inserted. The key cylinder and the handle lock mechanism L have the same interlocking relationship as that between the well-known motorcycle handle lock mechanism and the key cylinder so that the handle lock mechanism L can be locked in conjunction with the extraction operation of the ignition key. It has become. The key cylinder is configured to be able to open and close the main switch SW in conjunction with the key operation of the ignition key, similarly to a conventionally known ignition key key cylinder of a motorcycle.
[0024]
The transmitter T is provided with an operation switch 12 for operation input of lock / unlock, and a signal transmission unit capable of transmitting an infrared signal corresponding to a specific ID code in response to an operation input to the switch 12 (Not shown) is incorporated. The structure of such an infrared transmitter is well known in the art.
[0025]
The control device C includes an ID code verification unit C1 as a signal determination unit including a CPU and a memory, an actuator drive unit C2 that outputs an operation command signal to the lock actuator A, and a main relay 9 that outputs an operation command signal to the main relay 9. The relay drive means C3 and the power supply circuit C4 are provided.
[0026]
The ID code verification means C1 verifies whether the infrared signal received by the infrared receiver R is correct, that is, whether the ID code of the received signal matches a specific ID code stored in advance. When the ID code collating means C1 determines that the received signal is a normal infrared signal (the ID code is coincident), an operation command signal is output from the actuator driving means C2 to the lock actuator A.
[0027]
The main relay 9 is connected to the main relay driving means C3 and the main switch SW in the module housing 4, and when the main relay 9 is turned on, each on-vehicle electrical component 7 (including the engine start circuit) from the battery BA. Can be energized.
[0028]
Next, the operation of the embodiment will be described.
[0029]
Now, it is assumed that the scooter V is in the parking state and the handle lock mechanism L is in the locked state.
[0030]
In this state, when an infrared signal is emitted from the infrared transmitter T and received by the infrared receiver R, the ID code verification means C1 of the control device C determines whether the received signal is correct, that is, the ID code of the received signal. Is matched with a specific ID code stored in advance. When it is determined that the received signal is a normal infrared signal (the ID code matches), the actuator driving means C2 is turned on and outputs an operation command signal to the lock actuator A, whereby the actuator A is switched to the unlocked state, and thus the handle lock mechanism L is unlocked. At the same time, the ID code checking means C1 turns on the main relay driving means C3 to put the main relay 9 in the energization permitted state.
[0031]
Next, when the main switch SW is switched from OFF to ON by the key operation of the ignition key, the main relay 9 is turned ON and the main power supply is turned on, so that the electrical components 7 including the engine start circuit can be energized. It becomes a state. Therefore, in this state, if a start switch (not shown) is turned on by operating an ignition key or the like, the engine start circuit is energized to start the engine. Upon completion of the start, the scooter V can run. It becomes a state.
[0032]
In this embodiment, after the main relay 9 enters the energization permission state, the main relay 9 is in the energization permission state as described above in consideration of theft prevention when the main switch SW is left in the off state. If the main switch SW is not turned on even after a predetermined time has elapsed, the ID code verification means C1 turns off the main relay drive means C3 again to turn off the main relay 9 and invalidates the previous ID code verification. Thus, the control device C is programmed so that the lock actuator A is returned to the locked state again.
[0033]
Further, when stopping the running engine, the main switch SW is switched from on to off by the key operation of the ignition key. As a result, the power supply to the electric system of the engine is cut off and the engine is stopped. From this state, similarly to the conventionally known handle lock mechanism in motorcycles, when the ignition key is removed from the key cylinder, the lock mechanism L is locked in conjunction with this, and the steering shaft 1 can be locked. it can.
[0034]
In this embodiment, considering the prevention of theft when the engine is left stopped, the ID code collating means C1 turns off the main relay driving means C3 when a certain time has elapsed after the engine is stopped. The control device C is programmed so that 9 is in an energization non-permitted state and the previous ID code verification is invalidated (and thus the lock actuator A is returned to the locked state).
[0035]
If the main key SW is turned on by operating the ignition key while the handle lock mechanism L is locked, the lock actuator A can be operated to unlock the handle lock mechanism L regardless of the remote control lock operation system. it can. Therefore, like the conventional remote control door lock device for a vehicle, it can be unlocked by the ignition key without depending on the transmitter T.
[0036]
Thus, according to this embodiment, the handle lock mechanism L, the receiver R, the lock actuator A and its control device C, and the lock actuator A and the receiver R, which are the main components of the remote control lock operation system, are controlled. Since the wiring parts 5, 6 and the like connected to C are unitized in the common module housing 4 and are collectively attached to the vehicle body via the housing 4, the number of parts as a whole is small and handling is simple. Assembling workability to the vehicle body is also improved. In particular, since the wiring portion 5 connected to the lock actuator A can be concealed and protected in the module housing 4 so as not to be exposed to the outside, unauthorized locking / unlocking by directly connecting or changing the wiring portion 5 to the battery power supply BA is possible. As a result, vehicle theft can be effectively prevented.
[0037]
Furthermore, since the main switch SW and the main relay 9 are also incorporated in the module housing 4, the system can be further integrated (and therefore further cost-saving).
[0038]
FIG. 3 shows a second embodiment. In this embodiment, a drive permission signal generating means 20 that can generate a drive permission signal that is controlled by the control device C based on the received signal of the receiver R and permits the start or operation of the engine. It is provided in the module housing 4 together with the wiring part 21 connected to C.
[0039]
As the drive permission signal generating means 20, for example, a digital signal (on / off signal) output means for permitting / disallowing engine ignition (fuel injection), or a prescribed standard for permitting / disallowing ignition (fuel injection), for example. Voltage output means and digital code output means for enabling / disabling ignition (fuel injection) are used, and these output means are connected to an ignition control system, fuel injection control system or starter motor control system (not shown) of the engine. The
[0040]
Thus, according to this embodiment, even if the main power supply is turned on by an unauthorized means to the engine ignition control system, the fuel injection control system or the starter motor control system, the receiver R If the drive permission signal generating means 20 in the module housing 4 does not issue a drive permission signal based on the received regular received signal, the engine cannot be started or operated, which is more effective in preventing theft.
[0041]
FIG. 4 shows a third embodiment. In this embodiment, a transmitter T ′ and a receiver R ′ that transmit and receive a radio signal corresponding to a specific ID code are used instead of the transmitter T and the receiver R that transmit and receive an infrared signal. Therefore, the module housing 4 does not have the infrared receiver R, and instead, the antenna 30 and the radio wave receiving circuit 31 constituting the radio wave receiver R ′ are built in the housing 4.
[0042]
FIG. 5 shows a fourth embodiment. An indicator output means 40 is provided in the module housing 4. This indicator output means 40 is controlled by the control device C based on the reception signal of the infrared receiver R, and outputs a light emission signal to the indicator 42 formed of an LED or a light bulb of the vehicle instrument panel 41.
[0043]
As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various small design change is possible. For example, although the scooter is shown as the vehicle in the above embodiment, the “vehicle” in the present invention may be a two-wheeled vehicle other than the scooter, may be either a three-wheeled vehicle or a four-wheeled vehicle, and may or may not have a motor.
[0044]
In the above embodiment, the main switch SW can be opened and closed by the key operation of the ignition key. However, in the present invention, the main switch can be a manual switch or a remote control switch independent of the key operation of the ignition key. Good.
[0045]
In the above embodiment, the main switch SW and the main relay 9 are provided in the module housing 4. However, in the present invention (Claims 1 and 2 ), the main switch and the main relay are provided outside the module housing 4. May be. In the above embodiment, the key cylinder of the ignition key is arranged in the module housing 4 and has the required interlocking relationship with the main switch SW and the handle lock mechanism L. However, the key cylinder is installed in the module housing. 4 may be arranged close to the main switch SW and the handle lock mechanism L so as to have a required interlocking relationship with the main switch SW and the handle lock mechanism L.
[0046]
In the above-described embodiment, the handle lock mechanism L is manually locked (that is, interlocked with the extraction operation of the ignition key from the key cylinder), but in the present invention, only the handle lock mechanism L is unlocked. Alternatively, locking may be performed based on transmission signals from the transmitters T and T ′.
[0047]
【The invention's effect】
According to the present invention as described above, the remote control lock operation is a major component handle lock mechanism of the system, the receiver, the lock actuator, the control device, and wiring portion is unitized in a common module housing Since it is attached to the vehicle body collectively through the housing, the number of parts as a whole is small, the handling is easy, and the assembly workability to the vehicle body is also good, thus contributing to the reduction in size and weight of the system and cost reduction. In addition, it is possible to reduce the change of the vehicle body side mounting portion where the system is to be mounted as much as possible, and it is easy to implement. The wiring portion continuous to the lock actuator, it since it is possible concealed protection in the module housing so as not to be exposed to the outside, illegal unlocking by direct or rewiring of the battery power supply of the wiring portion, by extension Vehicle theft can be effectively prevented. In particular, the motorcycle has a steering shaft that is rotatably supported at the front of the vehicle body so as to steer the front wheel by interlocking the front fork and the steering handle, and a front body cover that covers the front side of the steering shaft. An inner cover that is coupled to the front body cover and covers the rear side of the steering shaft; and a handle cover that is disposed adjacent to the upper ends of both covers and covers the center of the steering handle and the upper end of the steering shaft. The module housing is disposed in the vehicle body space between the front body cover and the inner cover, and the signal receiving portion provided on the rear surface of the module housing of the receiver is located on the front side of the rear end portion of the handle cover. In the two-wheeled vehicle, the handle lock mechanism is integrated into the unit so that it is exposed backward through the opening formed in the rear end surface of the inner cover. Tsu DOO of remote control lock operation system can be obtained. Moreover it is possible to widely secure the directional range of the signal receiver of the receiver backward through an opening of the inner cover the rear end surface.
[0048]
Further, according to the invention of claim 2, even if the main power supply is turned on by an unauthorized means for the engine start system or the operation control system, the drive is permitted based on the normal received signal received by the receiver. As long as the signal generating means does not issue a drive permission signal, the engine cannot be operated, and therefore it is more effective in preventing theft of the vehicle.
[0049]
According to the invention of claim 3, since the main switch and the main relay are also incorporated in the module housing, the system can be further integrated, which can contribute to further cost saving .
