Description

Technical Field

[0001] The present invention relates to a wheel stopper drone, a wheel stopping method, and a vehicle system including the wheel stopper drone for preventing a vehicle such as a forklift or a cargo truck from starting moving in an unmanned state while the vehicle is parked.

Background Art

[0002] Since vehicles such as forklifts and cargo trucks have a large vehicle body weight, when a driver parks the vehicle, the driver operates a parking brake (side brake) to stop the vehicle so that it does not move. However, particularly when parking the vehicle on an inclined road surface, there is a risk that the vehicle may start moving in an unmanned state when the driver forgets to operate the parking brake or when the parking brake is not properly operated. Therefore, in addition to the parking brake, the driver installs wheel stoppers on the wheels of the vehicle to prevent the vehicle from starting moving in an unmanned state.

[0003] Since the driver manually installs the wheel stoppers on the wheels of the vehicle, when parking the vehicle on an inclined road surface, there is a risk that the vehicle may start moving while the driver is preparing the wheel stoppers. In particular, if the vehicle starts moving while the driver is installing the wheel stoppers on the wheels, there is a risk that the driver's hand or the like may be pinched by the wheels.

[0004] In addition, since the driver manually installs the wheel stoppers on the wheels of the vehicle, the driver may forget to install the wheel stoppers. Also, when the driver drives the vehicle, the vehicle can move by the driver manually removing and releasing the wheel stoppers from the wheels, but the driver may forget to release the wheel stoppers.

[0005] Particularly when parking the vehicle on an inclined road surface, if the driver forgets to install the wheel stoppers, there is a risk that the vehicle may start moving. Also, when the driver moves the vehicle, if the driver forgets to release the wheel stoppers, there is a risk that the vehicle may ride up on the wheel stoppers and tip over.

[0006] Therefore, for example, Patent Documents 1 and 2 disclose an apparatus configured to notify a driver of the installation and removal of wheel stoppers. However, in conventional wheel stoppers, the driver has to manually install and remove the wheel stoppers on the vehicle wheels, and even when notified, there is a risk of forgetting to install and remove the wheel stoppers.

[0007] Also, if the wheel stopper is not installed on the appropriate wheel, the wheel cannot be reliably stopped, and there is a risk that the vehicle will start moving.

Best Mode for Carrying Out the Invention

[0024] Hereinafter, based on the drawings, an embodiment of a wheel stopper drone, a wheel stopping method, and a vehicle system including the wheel stopper drone according to the present invention will be described. The X direction, Y direction, and Z direction are directions perpendicular to each other.

[0025] As shown in FIG. 1, the wheel stopper drone 1 includes a wheel stopper portion 2 and a main body portion 3. The wheel stopper portion 2 and the main body portion 3 have a predetermined width in the X direction (left - right direction), and the wheel stopper portion 2 and the main body portion 3 are connected in the Y direction (front - rear direction). In the present embodiment, the wheel stopper portion 2 and the main body portion 3 are configured to be connectable and separable for easy maintenance and inspection. Note that the wheel stopper portion 2 and the main body portion 3 may be integrated.

[0026] The wheel stopper portion 2 has a contact surface 2a on the front side in the Y direction. The main body portion 3 is connected to the rear side of the wheel stopper portion 2 in the Y direction. The contact surface 2a is configured such that the vehicle wheel abuts thereon. The contact surface 2a is inclined with respect to the Z direction (vertical direction) and has an arcuate curved shape. Thereby, the contact surface 2a can abut on the vehicle wheel so as to be in close contact therewith.

[0027] The wheel stopper drone 1 includes a plurality of rotors 4. In the present embodiment, four rotors 4 are provided on the main body portion 3 of the wheel stopper drone 1. Two rotors 4 are provided on the side surface side of the main body portion 3 in the X direction (left - right direction). The two rotors 4 provided on the side surface side of the main body portion 3 are arranged side by side in the Y direction (front - rear direction).

[0028] The number of rotors 4 is not limited to four and is determined according to the weight, stability, flight time, flight environment, etc. of the wheel stopper drone 1. Generally, when the number of rotors 4 is large, stable flight becomes possible. On the other hand, when the number of rotors 4 is small, it becomes lightweight, compact, and high - speed flight becomes possible.

[0029] The rotary wings 4 do not necessarily have to be provided on both side surfaces of the main body 3, and for example, they may be provided on the upper surface 3a of the main body 3. When the rotary wings 4 are arranged so as not to protrude from the upper surface 3a of the main body 3 as in the present embodiment, even when the vertical distance of the space between the lower surface of the vehicle body and the road surface is small, the wheel stopper drone 1 is installed in the space. However, if the rotary wings 4 are arranged on the upper surface 3a of the main body 3 or protrude from the upper surface 3a, the wheel stopper drone 1 may not be installed in the space when the vertical distance of the space between the lower surface of the vehicle body and the road surface is small. Therefore, by arranging the rotary wings 4 so as not to protrude from the upper surface 3a of the main body 3, the wheel stopper drone 1 can be installed for various vehicles.

[0030] As shown in FIG. 2, the wheel stopper drone 1 includes a plurality of motors 5 connected to each rotary wing 4, and the rotary wings 4 are rotated by driving the motors 5. Generally, the motor 5 is composed of a brushless motor, a permanent magnet is provided on the rotor side, and a three-phase winding is provided on the stator side.

[0031] The wheel stopper drone 1 includes a flight control unit 6 for controlling the drive of each motor 5. The flight control unit 6 includes an arithmetic unit 60 and a storage unit 61. The arithmetic unit 60 performs arithmetic operations based on signals from various sensors provided in the wheel stopper drone 1 and commands from the storage unit 61, and is configured to comprehensively control flight. As the main sensors, a pressure sensor for detecting altitude, a GPS for detecting the position information of the aircraft body, etc. are provided on the wheel stopper drone 1.

[0032] In addition, the wheel stopper drone 1 includes an inclination sensor 9 for measuring the inclination of the aircraft body. The inclination sensor 9 is composed of, for example, a gyro sensor and an acceleration sensor. When the wheel stopper drone 1 is installed on the vehicle 13, the inclination sensor 9 can detect the inclination direction of the road surface R on which the vehicle 13 is parked. Further, the inclination sensor 9 is connected to the flight control unit 6, and the detection signal from the inclination sensor 9 is configured to be transmitted to the flight control unit 6.

[0033] The wheel-stopping drone 1 is provided with a wireless communication unit 8 that receives signals from the remote controller 10. The wireless communication unit 8 consists of a modulation circuit, an amplification circuit, an antenna, etc. It amplifies and demodulates the radio waves received by the antenna, converts them into information signals, and transmits them to the flight control unit 6. The flight control unit 6 is configured to control the driving of each motor 5 based on the received signals. Also, the wheel-stopping drone 1 is provided with a battery 7 that serves as a power source for supplying power to each motor 5, the flight control unit 6, the wireless communication unit 8, etc.

[0034] An operator such as a vehicle driver can operate the flight of the wheel-stopping drone 1 with the remote controller 10. The remote controller 10 includes an operation unit 11 composed of a plurality of buttons, etc. for the operator to operate the flight of the wheel-stopping drone 1, and a wireless communication unit 12 that transmits operation signals from the operation unit 11.

[0035] The wireless communication unit 12 of the remote controller 10 is wirelessly connected to the wireless communication unit 8 of the wheel-stopping drone 1. The wireless communication unit 12 of the remote controller 10 consists of a modulation circuit, an amplification circuit, an antenna, etc. It amplifies and demodulates the signals received from the operation unit 11, converts them into radio waves, and transmits them to the wireless communication unit 8 of the wheel-stopping drone 1.

[0036] Vehicles 13 such as forklifts and cargo trucks are provided with a driving unit 130 composed of a motor, an engine, etc. mounted on the vehicle body, and a parking brake unit 131 composed of a side brake, etc. provided in the driver's seat. Further, the vehicle 13 is provided with a detection unit 132 for detecting the start and stop of the driving unit 130 or the operation and release of the parking brake unit 131, and a wireless communication unit 133 for transmitting signals from the detection unit 132 to the wireless communication unit 8 of the wheel-stopping drone 1.

[0037] Next, the operation of the wheel-stopping drone 1 will be described. As shown in FIGS. 3 and 4, the vehicle 13 includes a vehicle body 134 on which a driver's seat 136, a drive unit 130, a battery 137, etc. are mounted, and four wheels 135, 138 provided at the lower part of the vehicle body 134.

[0038] In this embodiment, the four wheels 135, 138 are composed of two front wheels 135 provided at the front of the vehicle 13 and two rear wheels 138 provided at the rear of the vehicle 13. The front wheels 135 are configured not to be able to turn with respect to the vehicle body 134, while the rear wheels 138 are configured to turn with respect to the vehicle body 134, and when steering the vehicle 13, the rear wheels 138 can be turned in conjunction with the steering wheel operation of the driver's seat 136. Therefore, the front wheels 135 do not turn and always face in the front-rear direction of the vehicle body 134.

[0039] In the vehicle 13, for example, a position such as behind the driver's seat 136 is a standby position 13a where the wheel-stopping drone 1 waits.

[0040] The vehicle 13 is provided with a power supply unit 70 for supplying power to the battery 7 of the wheel-stopping drone 1 at the standby position 13a. The power supply unit 70 is connected to the battery 137 mounted on the vehicle 13 and is composed of a contact-type or non-contact-type power supply device, and while the wheel-stopping drone 1 is waiting at the standby position 13a, power is supplied from the battery 137 of the vehicle 13 to the battery 7 of the wheel-stopping drone 1 through the power supply unit 70.

[0041] When parking the vehicle 13, an operator such as the driver of the vehicle 13 uses the remote controller 10 to fly the wheel-stopping drone 1 from the standby position 13a to an installation position 13b where the rolling of the vehicle wheel 135 is prevented. When the wheel-stopping drone 1 is arranged at the installation position 13b, the wheel-stopping part 2 of the wheel-stopping drone 1 is arranged to face the vehicle wheel 135. Thereby, the wheel stopping 2 by the wheel-stopping drone 1 is installed on the wheel 135, and the rolling of the wheel 135 is prevented.

[0042] Then, when the operator such as the driver of the vehicle 13 moves the vehicle 13, the operator can use the remote controller 10 to fly the wheel stopper drone 1 from the installation position 13b to the standby position 13a. As a result, the wheel stop by the wheel stopper drone 1 is released.

[0043] During the flight of the wheel stopper drone 1 between the standby position 13a and the installation position 13b by the operation of the operator, the storage unit 61 of the wheel stopper drone 1 is configured to store the driving of each motor 5. Accordingly, the wheel stopper drone 1 is configured to store the flight path between the standby position 13a and the set position 13b.

[0044] In addition, when the wheel stopper drone 1 receives a detection signal from the detection unit 132, it flies between the standby position 13a and the installation position 13b based on the flight path stored in the storage unit 61. When the detection unit 132 detects the stop of the drive unit 130 or the activation of the parking brake unit 131, the wheel stopper drone 1 flies from the standby position 13a to the installation position 13b. When the detection unit 132 detects the activation of the drive unit 130 or the release of the parking brake unit 131, the wheel stopper drone 1 flies from the installation position 13b to the standby position 13a.

[0045] In this embodiment, two wheel stopper drones 1 are configured to standby at the standby position 13a of each vehicle 13. Then, each wheel stopper drone 1 is installed at the installation position 13b of the wheels 135, 138, and the rolling of the wheels 135, 138 of the vehicle 13 can be prevented.

[0046] The wheel stopper drone 1 standby at the standby position 13a of the vehicle 13 can detect the inclination direction of the road surface R on which the vehicle 13 is parked by the inclination sensor 9.

[0047] As shown in FIG. 3(B), when the road surface R on which the vehicle 13 is parked is inclined, the installation positions 13b of the wheels 135 and 138 consist of a low position side 13b1 and a high position side 13b2 on the inclined road surface R with the wheels 135 and 138 interposed therebetween, and the low position side 13b1 is at a position lower than the high position side 13b2.

[0048] Therefore, the gravity acts on the wheels 135 and 138 of the vehicle 13 parked on the inclined road surface R so as to roll toward the low position side 13b1. And since no gravity acts on the high position side 13b2, the wheels 135 and 138 do not roll toward the high position side 13b2.

[0049] The storage unit 61 of the wheel stopper drone 1 stores the installation positions 13b of the respective wheels 135 and 138 and the flight path to the installation position 13b. Therefore, when the vehicle 13 is parked on the inclined road surface R, the wheel stopper drone 1 can be installed on the low position side 13b1 of the installation position 13b according to the flight path stored in the storage unit 61 and the inclination direction of the road surface R by the inclination sensor 9, and the rolling of the wheels 135 and 138 can be surely prevented.

[0050] In addition, since the non-steerable front wheel 135 always faces in the front-rear direction of the vehicle body 134, the wheel stopper drone 1 can be surely installed at the installation position 13b of the front wheel 135 regardless of the state of the steering wheel. Further, when the wheel stopper drone 1 flies based on the flight path stored in the storage unit 61, if it is the installation position 13b of the non-steerable front wheel 135, the angle of the front wheel 135 will not be changed, so it can be surely installed at the installation position 13b without changing the flight path.

[0051] Also, it is preferable that the two wheel stopper drones 1 are installed on the low position side 13b1 of the installation positions 13b of the front wheels 135 on both the left and right sides of the vehicle 13. This is because if the wheel stopper drone 1 is installed only on, for example, the left front wheel 135 instead of the front wheels 135 on both the left and right sides, the vehicle 13 may start to move clockwise when viewed from above due to the inclination of the road surface R.

[0052] The preferred embodiments of the present invention have been described above, but the configuration of the present invention is not limited to these embodiments. For example, it can also be changed as follows.

[0053] Instead of the wheel-stopping drone 1 automatically flying based on the flight path stored in the storage unit 61, the operator may manually fly the wheel-stopping drone 1 using the remote controller 10. In this case, the operator recognizes the inclination direction of the road surface R based on the detection result of the inclination sensor 9 or visual observation, and installs the wheel-stopping drone 1 on the lower position side 13b1 of the installation position 13b of the vehicles 135, 138.

[0054] Based on the relative three-dimensional coordinates of the standby position 13a and the installation position 13b with respect to the vehicle 13, the flight path of the wheel-stopping drone 1 may be simulated by a computer, and the storage unit 61 may be configured to store the flight path.

[0055] The vehicle 13 may be provided with a button for flying the wheel-stopping drone 1 near the driver's seat 136. As a result, when the driver presses the button when parking the vehicle 13, the wheel-stopping drone 1 flies from the standby position 13a to the installation position 13b, and when moving the vehicle 13, by pressing the button, the wheel-stopping drone 1 may fly from the installation position 13b to the standby position 13a.

[0056] The wheel-stopping drone 1 may be configured such that the wheel-stopping unit 2 and the main body unit 3 are integrated.

[0057] If the rear wheel 138 cannot turn, it is preferable to install the wheel-stopping drone 1 at the installation position 13b of the rear wheel 138. In this case, since the rear wheel 138 always faces in the front-rear direction of the vehicle 13 without changing its angle, it can be surely installed at the installation position 13b of the rear wheel 138 regardless of the state of the steering wheel and without changing the flight path.

[0058] Further, the inclination sensor 9 may be provided on the vehicle 13. In this case, the detection signal from the inclination sensor 9 is transmitted to the wireless communication unit 8 of the wheel stopper drone 1 through the wireless communication unit 133 of the vehicle 13.

[0059] The effects of the present invention will be described.

[0060] The wheel stopper drone 1 according to the present invention includes a wheel stopper portion 2 having a contact surface 2a for contacting the wheels 135, 138 of the vehicle 13 to stop the rolling of the wheels 135, 138, a plurality of rotors 4 for flying, and a battery 7 for driving the rotors 4.

[0061] Accordingly, since the driver does not need to manually install and remove the wheel stopper, there is no risk that the driver's hand or the like will be caught between the wheels of the vehicle while installing and removing the wheel stopper.

[0062] The wheel stopper drone 1 further includes a flight control unit 6 for controlling flight, and the flight control unit 6 controls to fly to the installation positions 13b of the non-steerable wheels 135, 138 with respect to the vehicle 13.

[0063] Accordingly, since the non-steerable wheels 135, 138 always face in the front-rear direction of the vehicle body 134, the wheel stopper drone 1 can be surely installed at the installation positions 13b of the wheels 135, 138 regardless of the state of the steering wheel. Further, when the wheel stopper drone 1 flies based on the flight path stored in the storage unit 61, since the angle of the wheels 135, 138 does not change as long as it is the installation position 13b of the non-steerable wheels 135, 138, it can be surely installed at the installation position 13b without changing the flight path.

[0064] Further, the flight control unit 6 controls to fly to the installation positions 13b of both the left and right wheels 135, 138 on the vehicle 13.

[0065] Thus, when the wheel-stopping drone 1 is installed only on, for example, the left front wheel 135 instead of both the left and right wheels 135 and 138, due to the inclination of the road surface R, the vehicle 13 may start to move clockwise when viewed from above. However, by installing the wheel-stopping drone 1 at the installation positions 13b of both the left and right wheels 135 and 138, it is possible to surely prevent the vehicle 13 from starting to move.

[0066] Further, the flight control unit 6 controls the drone 1 to fly to the lower position side 13b1 of the installation position 13b that stops the rolling of the wheels 135 and 138 of the vehicle 13 based on the inclination direction of the road surface R on which the vehicle 13 is parked.

[0067] The wheels 135 and 138 of the vehicle 13 parked on the inclined road surface R are affected by gravity so as to roll to the lower position side 13b1. Therefore, when the vehicle 13 is parked on the inclined road surface R, by installing the wheel-stopping drone 1 on the lower position side 13b1 of the installation position 13b, it is possible to surely prevent the wheels 135 and 138 from rolling.

[0068] Further, the inclination direction of the road surface R is configured to be detected by an inclination sensor 9 provided on the wheel-stopping drone 1 or the vehicle 13.

[0069] The wheel-stopping drone 1 or the vehicle 13 is provided with an inclination sensor 9 for measuring the inclination angle of the airframe for flight or travel. By using this inclination sensor 9, the inclination direction of the road surface R can be detected.

[0070] Further, each rotor 4 is provided on both side portions of the wheel-stopping drone 1 and on the rear side of the contact surface 2a.

[0071] As a result, the distance by which the rotor 4 protrudes above the upper surface of the wheel-stopping drone 1 becomes smaller. Therefore, even when the vertical distance of the space between the lower surface of the vehicle body 134 of the vehicle and the passage is small, the wheel-stopping drone 1 can be installed in this space.

[0072] In addition, the wheel stopper drone 1 includes a storage unit 61 for storing the flight path along which the wheel stopper drone 1 has flown, and is configured to fly along the flight path stored in the storage unit 61.

[0073] As a result, an operator such as a driver does not need to operate the wheel stopper drone 1 to fly between the standby position 13a where the wheel stopper drone 1 waits and the installation position 13b where the rolling of the vehicle wheel 135 is prevented, and can fly automatically along the flight path. Also, although the standby position 13a and the installation position 13b differ for each vehicle 13, by storing the actual flight path along which the wheel stopper drone 1 has flown, a flight path corresponding to each vehicle 13 can be stored.

[0074] In addition, the vehicle 13 includes a detection unit 132 for detecting the start and stop of the drive unit 130 of the vehicle 13, and a wireless communication unit 133 for transmitting a detection signal from the detection unit 132. The wheel stopper drone 1 includes a wireless communication unit 8 for receiving the detection signal, and a flight control unit 6 for controlling flight along the flight path based on the detection signal.

[0075] In addition, the vehicle 13 includes a detection unit 132 for detecting the actuation and release of the parking brake unit 131 of the vehicle 13, and a wireless communication unit 133 for transmitting a detection signal from the detection unit 132. The wheel stopper drone 1 includes a wireless communication unit 8 for receiving the detection signal, and a flight control unit 6 for controlling flight along the flight path based on the detection signal.

[0076] Accordingly, when the detection unit 132 detects the stop of the drive unit 130 or the activation of the parking brake unit 131, the wheel stop drone 1 is configured to fly from the standby position 13a to the installation position 13b. Further, when the detection unit 132 detects the activation of the drive unit 130 or the release of the parking brake unit 131, the wheel stop drone 1 is configured to fly from the installation position 13b to the standby position 13a. As a result, an operator such as a driver will not forget to fly the wheel stop drone 1, so that the wheel stop can be surely installed on and removed from the wheel 135.

[0077] In addition, the vehicle 13 includes the wheel stop drone 1 and a standby position 13a for waiting for the wheel stop drone 1, and includes a power supply unit 70 for supplying power to the battery 7 of the wheel stop drone 1 at the standby position 13a.

[0078] Accordingly, while the wheel stop drone 1 is waiting at the standby position 13a, power can be supplied from the battery 137 of the vehicle 13 to the battery 7 of the wheel stop drone 1 through the power supply unit 70.
