Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the above bicycle mounting device easily performs management of the device itself and management of the housing provided in the device in a bicycle, which is a form of vehicle. Two-wheeled or three-wheeled bicycles (electric assist bicycles) equipped with an electric motor as a power source, or motorcycles or three-wheeled vehicles that automatically run by the power of an internal combustion engine or an electric motor, and furthermore, vehicles such as two-wheeled or three-wheeled senior cars equipped with an electric motor as a power source are non-enclosed vehicles that do not have an enclosed driver's cab, unlike general four-wheeled automobiles.

[0005] When the bicycle mounting device described above, based on the background technology, is applied to additional equipment in such non-enclosed vehicles, the need to manage a common key (lock key) arises, resulting in poor usability. For example, since many users of mobility scooters are disabled or elderly, managing the lock key is a critical issue that needs to be addressed.

[0006] This invention has been made in view of the circumstances described above, and aims to provide a vehicle locking device that eliminates the need for lock key management in vehicles equipped with a power source. [Means for solving the problem]

[0007] To achieve the above objective, the present invention provides a first solution relating to a vehicle speed limiting device, which is a vehicle locking device that switches the engagement between a support member and a supported member provided on a vehicle between a locked state and an unlocked state, and which switches between the locked state and the unlocked state based on the activation signal of the power source in the vehicle.

[0008] In the present invention, as a second solution relating to a vehicle speed limiting device, the first solution described above is provided with a solenoid that switches between a locked state and an unlocked state, a solenoid drive circuit that drives the solenoid based on the activation signal, and a harness that electrically connects the solenoid and the solenoid drive circuit.

[0009] In the present invention, as a third solution relating to a vehicle speed limiting device, the solenoid drive circuit is provided with a circuit that outputs a one-shot pulse at the transition point of the activation signal and a mechanism that latches lock and unlock with the one-shot pulse, in the second solution described above.

[0010] In the present invention, as a fourth solution relating to a vehicle speed limiting device, the method adopted is that, in the second or third solution described above, the supported member is the main body of a device that functions as a drive recorder.

[0011] In the present invention, as a fifth solution relating to a vehicle speed limiting device, the second or third solution described above employs the following means: the vehicle is an electric motorcycle that uses an electric motor as its power source, and the starting signal is a power-on signal of the control device for the electric motor. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a vehicle locking device that eliminates the need for managing lock keys in vehicles equipped with a power source. [Brief explanation of the drawing]

[Figure 7] This is a circuit diagram showing the main components of a vehicle locking device according to a modified example of one embodiment of the present invention. [Modes for carrying out the invention]

[0014] One embodiment of the present invention will be described below with reference to the drawings. First, the drive recorder A in this embodiment will be described. This drive recorder A is an add-on device that is retrofitted to an electric motorcycle (product vehicle), which is a type of vehicle, and comprises a support unit 1 and a device body 2, as shown in Figures 1 and 2.

[0015] As shown in the figure, the fixing unit 1 includes a clamp 1a for attaching to a motorcycle, a connecting portion 1b, a mounting and power supply unit 1c, and a connection cable 1d. The clamp 1a for attaching to a motorcycle is fixedly attached to the handlebar of an electric two-wheeler (motorcycle). The clamp 1a for attaching to a motorcycle includes an upper clamp 1a1 and a lower clamp 1a2, and the handlebar of the electric two-wheeler (motorcycle) is fixedly attached by connecting the upper clamp 1a1 and the lower clamp 1a2 with a connecting bolt (not shown) or the like to sandwich the handlebar from above and below.

[0016] The connecting portion 1b is provided between the clamp 1a for attaching to a motorcycle and the mounting and power supply unit 1c, and is a portion that connects the two. The connecting portion 1b connects a clamp-side protruding portion 1a3 protruding upward from the upper surface of the clamp 1a for attaching to a motorcycle and a unit-side protruding portion 1c1 protruding downward from the lower surface of the mounting and power supply unit 1c using a connecting screw (not shown).

[0017] That is, screw insertion holes into which a connecting screw is commonly inserted are formed in the clamp-side protruding portion and the unit-side protruding portion. The connecting portion 1b connects the clamp 1a for attaching to a motorcycle and the mounting and power supply unit 1c by inserting a connecting screw into the screw insertion hole, and can adjust the elevation angle of the device main body 2 mounted on the mounting and power supply unit 1c.

[0018] The mounting and power supply unit 1c is a pedestal fixed above the clamp 1a for attaching to a motorcycle by such a connecting portion 1b. As shown in FIGS. 3 and 4, the mounting and power supply unit 1c includes a housing portion 1c2, a sealing material 1c3, a lid member 1c4, and a power contact 1c5 as a structural portion viewed from above.

[0019] The housing portion 1c2 is a box-shaped resin member. The sealing material 1c3 is attached to the upper end surface of the housing portion 1c2, which is rectangular and flat. Further, as shown in FIG. 4, the housing portion 1c2 has a box-shaped internal space S. The lock device B according to the present embodiment is housed in the internal space S.

[0020] The sealing material 1c3 is an annular collapsible member, for example, a rubber ring-shaped member. This sealing material 1c3 extends annularly along the upper end surface of the above-mentioned accommodating portion 1c2, that is, a rectangular plane. Such a sealing material 1c3 is compressed in the vertical direction between the bottom surface (plane) of the device main body 2 placed on the mounting and power supply unit 1c in a predetermined posture from above and the upper end surface (plane) of the accommodating portion 1c2, thereby ensuring the airtightness of the internal space S of the accommodating portion 1c2.

[0021] The lid member 1c4 is a rectangular flat plate that closes the upper opening (rectangular opening) of the accommodating portion 1c2. A pair of openings 1c6 and 1c7 are formed in this lid member 1c4 at a predetermined interval. These pair of openings 1c6 and 1c7 are rectangular openings as shown in FIG. 3. Further, a power contact 1c5 is provided on the lid member 1c4 as shown in FIG. 3.

[0022] The power contact 1c5 is provided on the lid member 1c4 at a position corresponding to a connection terminal (not shown) provided on the bottom surface of the device main body 2. This power contact 1c5 has at least three contacts. Among these three contacts, the first contact is a power supply contact, the second contact is a ground contact, and the third contact is a control contact.

[0023] The connection cable 1d is an electric wire that electrically connects the mounting and power supply unit 1c and the electric two-wheeler (motorcycle), and for example, includes three core wires. Among the three core wires, the first core wire is a power supply core wire and is connected to the first connection terminal (power supply connection terminal) among, for example, three connection terminals (not shown) provided on the upper surface of the mounting and power supply unit 1c.

[0024] The second core wire is a grounding core wire and is connected to the second connection terminal (grounding connection terminal) of the mount / power supply unit 1c. The third core wire is a control core wire and is connected to the third connection terminal (control connection terminal) of the mount / power supply unit 1c. This connection cable 1d supplies power Vcc and control signals to the device body 2 via three connection terminals, and supplies power Vcc and the start signal PO to the lock device B. Note that in some vehicle models, the start signal PO is replaced by the rising edge of the Vcc signal, in which case there are two core wires.

[0025] Here, the activation signal PO is a step signal that switches the operating state of the locking device B, i.e., the locked state or the unlocked state. This activation signal PO is a signal that indicates the activation of the power source of the electric motorcycle, i.e., the electric motor. For example, this activation signal PO is the power-on signal of the control device for the electric motor (power source).

[0026] This start signal PO sets lock device B to the unlocked state by transitioning from a low level to a high level, and sets lock device B to the locked state by transitioning from a high level to a low level. In other words, when the motor starts, the start signal PO sets lock device B to the unlocked state, and when the motor starts and stops, it sets lock device B to the locked state.

[0027] On the other hand, the main unit 2 of this drive recorder A has the function of capturing and saving (memorizing) images of the area in front of the electric motorcycle. As shown in Figure 4, the main unit 2 is formed in a box shape, and the three connection terminals (not shown) described above are provided on the bottom surface. As will be described in detail later, these three connection terminals are connected to the three core wires of the connection cable 1d via the mount and power supply unit 1c.

[0028] Furthermore, the device body 2 is equipped with a pair of latch plates 2a1 and 2a2 that protrude downward from the bottom surface (flat surface). Of the pair of latch plates 2a1 and 2a2, one latch plate 2a1 is positioned to correspond to one of the openings 1c6 formed in the lid member 1c4 of the mount and power supply unit 1c.

[0029] Of the pair of latch plates 2a1 and 2a2, the other latch plate 2a2 is positioned to correspond to the other opening 1c7 formed in the lid member 1c4 of the mount and power supply unit 1c. Furthermore, as shown in the figure, the other latch plate 2a2 has a locking hole 2a3 near its tip (lower end).

[0030] In this device, the main body 2 is held in place (latched) on the mount / power supply unit 1c by the function of a latch mechanism (not shown) provided on the mount / power supply unit 1c, when the pair of latch plates 2a1 and 2a2 are inserted into the pair of openings 1c6 and 1c7 of the mount / power supply unit 1c.

[0031] In other words, in this embodiment of the drive recorder A, the main unit 2 and the mount / power supply unit 1c are engaged by a latch mechanism, thereby maintaining the mounting state of the main unit 2 to the mount / power supply unit 1c.

[0032] As shown in Figure 4, the housing section 1c2 of the mount and power supply unit 1c is provided with a pair of release buttons 1c8 and 1c9. These release buttons 1c8 and 1c9 are operating parts for releasing the latched state of the device body 2 by the latch mechanism. By pressing the pair of release buttons 1c8 and 1c9 toward the housing section 1c2, the latched state of the device body 2 is released, and the device body 2 can be removed from the mount and power supply unit 1c.

[0033] The locking device B according to this embodiment switches the engagement between the device body 2 and the mount / power supply unit 1c in the drive recorder A between a locked state and an unlocked state, and is provided inside the mount / power supply unit 1c as shown in Figure 4. In other words, this locking device B prevents unintended removal of the device body 2 by strengthening the engagement state between the device body 2 and the mount / power supply unit 1c through a latch mechanism (not shown).

[0034] As shown in Figure 5, such a locking device B comprises a solenoid 3, a harness 4, and a solenoid drive unit 5. The solenoid 3 is equipped with a plunger 3a that can move forward (to the right in the drawing) and backward (to the left in the drawing), and the plunger 3a is moved forward / backward using magnetic force. The plunger 3a is positioned to correspond to a lock hole 2a3 provided in the other latch plate 2a2.

[0035] Such a solenoid 3 is equipped with a pair of input and output terminals. This solenoid 3 generates a magnetic field whose polarity is set based on the direction of the drive signal (drive current) input to the pair of input and output terminals from the solenoid drive unit 5, and moves the plunger 3a forward / backward with the magnetic force obtained from this magnetic field.

[0036] In other words, the solenoid 3 advances the plunger 3a when a drive current flows in from one of the pair of input / output terminals, and retracts the plunger 3a when a drive current flows in from the other of the pair of input / output terminals.

[0037] In this locking device B, the unlocked state is when the plunger 3a of the solenoid 3 retracts, separating it from the lock hole 2a3, as shown in Figure 5(a). Conversely, in this locking device B, the locked state is when the plunger 3a of the solenoid 3 advances and is inserted into the lock hole 2a3, as shown in Figure 5(b).

[0038] The harness 4 is an electrical wire that electrically connects the solenoid 3 and the solenoid drive unit 5. The harness 4 has a pair of core wires. In the harness 4, one end of the first core wire is connected to the first output terminal of the locking device B, and the other end is connected to the input terminal of the solenoid 3. In the harness 4, one end of the second core wire is connected to the second output terminal of the locking device B, and the other end is connected to the output terminal of the solenoid 3.

[0039] Such a harness 4 supplies the drive signal output from the solenoid drive unit 5 to the solenoid 3. The solenoid 3, as described above, moves the plunger 3a forward / backward when the drive signal is supplied from the solenoid drive unit 5 via the harness 4.

[0040] The solenoid drive unit 5 is an electrical component in which a circuit that generates the above-mentioned drive signal based on power supplied from an electric motorcycle via a connecting cable 1d and a start signal PO is mounted on a circuit board. This solenoid drive unit 5 has a circuit configuration as shown in Figure 6(a), for example.

[0041] In other words, the solenoid drive unit 5 is an electronic circuit with two inputs and two outputs, and is operated by a power supply Vcc (DC power supply) supplied to the power supply terminal. Of the pair of input terminals, the first input terminal is connected to the third contact (control contact) of the power supply contact 1c5, and the aforementioned start signal PO is input to it. The second input terminal is connected to the second contact (grounding contact) of the power supply contact 1c5 and is grounded. The power supply terminal is connected to the first contact (power supply contact) of the source contact 1c5, and the power supply Vcc is supplied to it.

[0042] Such a solenoid drive unit 5 includes, as circuit elements, a first inverter 5a, a pair of monomultiplexers 5b and 5c, a second inverter 5d, a first buffer 5e, a third inverter 5f, a second buffer 5g, and first to fourth transistors 5h to 5k.

[0043] The first inverter 5a has its input terminal connected to the first input terminal and its output terminal connected to the input terminal of the first mono multifunction 5b. The first inverter 5a receives a start signal PO via the first input terminal and outputs an inverted start signal POi, which is the logical inversion of the start signal PO, to the first mono multifunction 5b.

[0044] Of the pair of monomultiplexers 5b and 5c, the first monomultiplexer 5b is a one-shot multivibrator, and its input terminal is connected to the output terminal of the first inverter 5a. The output terminal of this first monomultiplexer 5b is also connected to the input terminal of the second inverter 5d and the input terminal of the first buffer 5e.

[0045] Such a first monomultiplex 5b generates a first holding signal S1 at the transition point of the inverting start signal POi input from the first inverter 5a, which sets the output voltage to a high or low level, and outputs the first holding signal S1 to the second inverter 5d and the first buffer 5e.

[0046] The second mono multivibrator 5c is a one-shot multivibrator, similar to the first mono multivibrator 5b. The input terminal of this second mono multivibrator 5c is connected to the first input terminal, and its output terminal is connected to the input terminal of the third inverter 5f and the input terminal of the second buffer 5g.

[0047] This second mono multifunction 5c generates a second holding signal S2 at the transition point of the startup signal PO input from the first input terminal, which sets the output voltage to either a high or low level, and outputs the second holding signal S2 to the third inverter 5f and the second buffer 5g.

[0048] Here, the first monomultiplexer 5b is a circuit that outputs a one-shot pulse at the transition point of the inverted start signal POi. The second monomultiplexer 5c is a circuit that outputs a one-shot pulse at the transition point of the start signal PO. In other words, the pair of monomultiplexers 5b and 5c are circuits that output a one-shot pulse at the transition point of the inverted start signal POi and the start signal PO.

[0049] The first hold signal S1 generated by the first mono multifunction 5b and the second hold signal S2 generated by the second mono multifunction 5c are in a phase-inverted relationship, similar to the phase-inverted relationship between the inverted start signal POi input to the first mono multifunction 5b and the start signal PO input to the second mono multifunction 5c.

[0050] The second inverter 5d has its input terminal connected to the output terminal of the first monomultiplex 5b, and its output terminal connected to the base terminal of the first transistor 5h. The second inverter 5d receives the first hold signal S1 from the first monomultiplex 5b and outputs the first inverted hold signal S1i, which is the logic inverted version of the first hold signal S1, to the first transistor 5h.

[0051] The first buffer 5e has its input terminal connected to the output terminal of the first monomultiplex 5b, and its output terminal connected to the base terminal of the fourth transistor 5k. The first buffer 5e receives the first hold signal S1 from the first monomultiplex 5b, buffers the first hold signal S1, and outputs it to the fourth transistor 5k.

[0052] The third inverter 5f has its input terminal connected to the output terminal of the second monomultiplex 5c, and its output terminal connected to the base terminal of the third transistor 5j. The third inverter 5f receives the second hold signal S2 from the second monomultiplex 5c and outputs a second inverted hold signal S2i, which is the logic inverted version of the second hold signal S2, to the third transistor 5j.

[0053] The second buffer 5g has its input terminal connected to the output terminal of the second mono multifunction 5c, and its output terminal connected to the base terminal of the second transistor 5i. The second buffer 5g receives the second hold signal S2 from the second mono multifunction 5c, buffers the second hold signal S2, and outputs it to the second transistor 5i.

[0054] The first to fourth transistors 5h to 5k form a bridge circuit as shown in the diagram. Of the first to fourth transistors 5h to 5k, the first transistor 5h and the third transistor 5j are PNP bipolar transistors as shown in the diagram, while the second transistor 5i and the fourth transistor 5k are NPN bipolar transistors as shown in the diagram.

[0055] The base terminal of the first transistor 5h is connected to the output terminal of the second inverter 5d, and the emitter terminal is connected to the power supply terminal. In addition, the collector terminal of this first transistor 5h is connected to the collector terminal of the second transistor 5i and the first core wire of harness 4.

[0056] The base terminal of the second transistor 5i is connected to the output terminal of the second buffer 5g. The collector terminal of this second transistor 5i is connected to the collector terminal of the first transistor 5h and the first core wire of harness 4, and the emitter terminal is grounded.

[0057] The third transistor 5j has its base terminal connected to the output terminal of the third inverter 5f, and its emitter terminal connected to the power supply terminal. Furthermore, the collector terminal of this third transistor 5j is connected to the collector terminal of the fourth transistor 5k and the second core wire of harness 4.

[0058] The base terminal of the fourth transistor 5k is connected to the output terminal of the first buffer 5e. The collector terminal of this fourth transistor 5k is connected to the collector terminal of the third transistor 5j and the second core wire of harness 4, and the emitter terminal is grounded.

[0059] This bridge circuit, consisting of the first to fourth transistors 5h to 5k, supplies a drive signal (drive current) to the solenoid 3 via the harness 4. Furthermore, this bridge circuit switches the direction of the drive current supply to the solenoid 3 according to the start signal PO supplied from the electric motorcycle to the drive recorder A.

[0060] In this embodiment, the electric motorcycle corresponds to the vehicle in the present invention. The motorcycle mounting clamp 1a, connecting part 1b, and mount / power supply unit 1c in this embodiment correspond to the support member in the present invention. Furthermore, the device body 2 in this embodiment corresponds to the supported member in the present invention.

[0061] Next, the operation of the locking device B according to this embodiment will be described in detail with reference to Figure 6(b).

[0062] As shown in Figure 6(b), when the start signal PO supplied from the electric motorcycle to the drive recorder A transitions from a low level to a high level, the drive signal output from the solenoid drive unit 5 to the solenoid 3 transitions from the base level to a low level. As a result, the locking device B is set to the unlocked state.

[0063] In this unlocked state, the device body 2 can be removed from the mount / power supply unit 1c by pressing the pair of release buttons 1c8 and 1c9 to release the latch on the device body 2. In other words, the unlocked state makes it easy to attach and detach the device body 2.

[0064] In other words, the locking device B according to this embodiment sets its operating state to the unlocked state when the electric motor of the electric motorcycle is started. The starting of the electric motor occurs when the user of the electric motorcycle starts using the electric motorcycle and the user is in close proximity to the electric motorcycle.

[0065] In response to this, as shown in Figure 6(b), the start signal PO supplied from the electric motorcycle to the drive recorder A transitions from a high level to a low level. As a result, the drive signal output from the solenoid drive unit 5 to the solenoid 3 transitions from the base level to a high level.

[0066] In this locked state, the plunger 3a of the solenoid 3 is advanced and inserted into the lock hole 2a3, so pressing the pair of release buttons 1c8 and 1c9 will not release the latch of the device body 2. In this locked state, the device body 2 cannot be attached or detached.

[0067] In other words, the locking device B according to this embodiment sets its operating state to the locked state (LOCK) when the electric motor of the electric motorcycle starts or stops. This starting or stopping of the electric motor indicates that the user has finished using the electric motorcycle and serves as an opportunity for the user to leave the electric motorcycle.

[0068] The locking device B according to this embodiment switches the engagement between the motorcycle mounting clamp 1a, connecting part 1b, and mount / power unit 1c (supporting member) provided on the electric motorcycle (vehicle) and the device body 2 (supported member) between a locked state and an unlocked state, and switches between the locked state and the unlocked state based on the start signal PO of the electric motor (power source) of the electric motorcycle (vehicle).

[0069] According to this embodiment, since the locked state and unlocked state are switched based on the start signal PO of the electric motor (power source) of the electric motorcycle (vehicle), it is possible to provide a vehicle locking device B that does not require the management of a lock key in an electric motorcycle (vehicle) equipped with an electric motor as a power source.

[0070] Furthermore, the locking device B according to this embodiment includes a solenoid 3 that switches between a locked state and an unlocked state, a solenoid drive circuit 5 that drives the solenoid 3 based on a starting signal PO, and a harness 4 that electrically connects the solenoid 3 and the solenoid drive circuit 5. According to this embodiment, it is possible to reliably switch between a locked state and an unlocked state by moving the plunger 3a of the solenoid 3 forward / backward based on the starting signal PO.

[0071] Furthermore, in the locking device B according to this embodiment, the solenoid drive circuit 5 includes a pair of monomulti 5b and 5c (latch circuits) that latch the transition points of the inverting start signal POi and the start signal PO, respectively. According to this embodiment, it is possible to stably switch between the locked state and the unlocked state.

[0072] Furthermore, in the locking device B according to this embodiment, the device body 2 (supported member) is the device body that functions as a drive recorder A. According to this embodiment, it is possible to switch between the locked state and the unlocked state of the drive recorder A that has been added to the electric motorcycle (vehicle).

[0073] Furthermore, in the locking device B according to this embodiment, the vehicle is an electric motorcycle powered by an electric motor, and the starting signal PO is the power-on signal in the electric motor's control device. According to this embodiment, since the power-on signal of the control device is used as the starting signal PO, it is possible to accurately switch between the locked state and the unlocked state.

[0074] The present invention is not limited to the embodiments described above, and for example, the following modifications are possible. (1) In the above embodiments, the case in which the present invention is applied to an electric two-wheeled vehicle (motorcycle) has been described, but the present invention is not limited thereto. The present invention can be applied to vehicles such as two-wheeled or three-wheeled bicycles (electric assist bicycles) equipped with an electric motor as a power source, or two-wheeled or three-wheeled motorcycles that automatically move using the power of an internal combustion engine or an electric motor, and even two-wheeled or three-wheeled mobility scooters equipped with an electric motor as a power source.

[0075] (2) In the above embodiment, the circuit configuration shown in Figure 6(a) was adopted, but the present invention is not limited thereto. A circuit configuration that does not include a circuit for outputting a one-shot pulse is also possible for the solenoid drive unit 5. For example, Figure 7 is an example of a circuit configuration that does not include a circuit for outputting a one-shot pulse, in which the start signal PO is supplied directly to the solenoid 3 as a drive signal.
