Description

Technical Field

[0001] The present invention relates to a wheel stopper drone, a wheel stopping method, and a vehicle system equipped with a 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 from moving. However, especially 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 operated properly. 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 caught between the wheels.

[0004] Also, 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] In particular, 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, the driver may forget to install and remove the wheel stoppers.

[0007] In particular, when the vehicle is parked on an inclined road surface, if the wheel stopper is not installed on the appropriate wheel, the vehicle may start to move due to the inclination of the road surface.

Embodiments 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, the Y direction, and the Z direction are directions orthogonal 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 rotary wings 4. In the present embodiment, the wheel stopper drone 1 has four rotary wings 4 provided on the main body portion 3. Two rotary wings 4 are provided on each of the side surfaces of the main body portion 3 in the X direction (left - right direction). The two rotary wings 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 the rotary wings 4 is not limited to four, and is determined according to the weight, stability, flight time, flight environment, etc. of the wheel-stopping drone 1. Generally, when the number of the rotary wings 4 is large, stable flight becomes possible, while when the number of the rotary wings 4 is small, it becomes lightweight, compact, and capable of high-speed flight.

[0029] The rotary wings 4 do not necessarily have to be provided on both side surfaces of the main body 3. 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 more than 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 of the vehicle and the road surface is small, the wheel-stopping 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 so as to protrude from the upper surface 3a, when the vertical distance of the space between the lower surface of the vehicle body of the vehicle and the road surface is small, the wheel-stopping drone 1 may not be installed in the space. Therefore, by arranging the rotary wings 4 so as not to protrude more than the upper surface 3a of the main body 3, the wheel-stopping drone 1 can be installed for various vehicles.

[0030] As shown in FIG. 2, the wheel-stopping 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-stopping drone 1 includes a flight control unit 6 for controlling the driving 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-stopping drone 1 and commands from the storage unit 61, and is configured to comprehensively control the 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 in the wheel-stopping drone 1.

[0032] In addition, the wheel-stopping drone 1 is provided with an inclination sensor 9 for measuring the inclination of the aircraft body. The inclination sensor 9 consists of, for example, a gyro sensor and an acceleration sensor. When the wheel-stopping 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 is configured such that a detection signal from the inclination sensor 9 is transmitted to the flight control unit 6.

[0033] The wheel-stopping drone 1 is provided with a wireless communication unit 8 for receiving a signal from the remote controller 10. The wireless communication unit 8 consists of a modulation circuit, an amplification circuit, an antenna, etc., amplifies and demodulates the radio wave received by the antenna, converts it into an information signal, and transmits it to the flight control unit 6. The flight control unit 6 is configured to control the drive of each motor 5 based on the received signal. In addition, 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 driver of the vehicle can operate the flight of the wheel-stopping drone 1 by means of the remote controller 10. The remote controller 10 includes an operation unit 11 consisting 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 for transmitting an operation signal 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., amplifies and demodulates the signal received from the operation unit 11, converts it into a radio wave, and transmits it to the wireless communication unit 8 of the wheel-stopping drone 1.

[0036] Vehicles 13 such as forklifts and cargo trucks are equipped with a drive 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 equipped with a detection unit 132 for detecting the start and stop of the drive unit 130 or the operation and release of the parking brake unit 131, and a wireless communication unit 133 for transmitting a signal from the detection unit 132 to the wireless communication unit 8 of the wheel stopper drone 1.

[0037] Next, the operation of the wheel stopper 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 are always oriented 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 stopper 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 stopper 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 is configured such that power is supplied from the battery 137 of the vehicle 13 to the battery 7 of the wheel stopper drone 1 through the power supply unit 70 while the wheel stopper drone 1 is waiting at the standby position 13a.

[0041] When the operator such as the driver of the vehicle 13 parks the vehicle 13, using the remote controller 10, the wheel stopper drone 1 flies from the standby position 13a to the installation position 13b where it prevents the rolling of the vehicle wheel 135. When the wheel stopper drone 1 is disposed at the installation position 13b, the wheel stopper portion 2 of the wheel stopper drone 1 is disposed to face the vehicle wheel 135. Thereby, the wheel stopper 2 by the wheel stopper 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, using the remote controller 10, the operator can fly the wheel stopper drone 1 from the installation position 13b to the standby position 13a. Thereby, the wheel stopper by the wheel stopper drone 1 is released.

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

[0044] Also, when the wheel stopper drone 1 receives the detection signal from the detection unit 132, based on the flight path stored in the storage unit 61, the wheel stopper drone 1 flies between the standby position 13a and the installation position 13b. 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. Also, 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-stopping drones 1 are configured to standby at the standby position 13a of the vehicle 13 for each vehicle 13. Then, each wheel-stopping drone 1 is installed at the installation position 13b of the wheels 135, 138 so that the rolling of the wheels 135, 138 of the vehicle 13 can be prevented.

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

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

[0048] Therefore, the gravity acts on the wheels 135, 138 of the vehicle 13 parked on the inclined road surface R so that they roll to the low position side 13b1. And since the gravity does not act on the high position side 13b2, the wheels 135, 138 do not roll to the high position side 13b2.

[0049] The storage unit 61 of the wheel-stopping drone 1 stores the installation position 13b of each wheel 135, 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-stopping 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, 138 can be surely prevented.

[0050] In addition, since the non-steerable front wheel 135 always faces in the longitudinal direction of the vehicle body 134, the wheel-stopping 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-stopping 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, the two wheel-stopping drones 1 are preferably installed on the lower 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-stopping 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] As described above, the preferred embodiments of the present invention have been described, but the configuration of the present invention is not limited to these embodiments. For example, it can also be changed as follows.

[0053] The operator may manually fly the wheel-stopping drone 1 using the remote controller 10 without the wheel-stopping drone 1 automatically flying based on the flight path stored in the storage unit 61. 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 stopper drone 1 near the driver's seat 136. As a result, when the driver parks the vehicle 13 and presses the button, the wheel stopper drone 1 flies from the standby position 13a to the installation position 13b, and when the vehicle 13 is moved and the button is pressed, the wheel stopper drone 1 may fly from the installation position 13b to the standby position 13a.

[0056] The wheel stopper drone 1 may be integrally configured with the wheel stopper portion 2 and the main body portion 3.

[0057] If the rear wheel 138 cannot turn, it is preferable to install the wheel stopper 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] Also, the inclination sensor 9 may be provided on the vehicle 13. In that 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 rotating wings 4 for flying, and a battery 7 for driving the rotating wings 4.

[0061] As a result, 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 pinched by the vehicle's wheels while installing and removing the wheel stopper.

[0062] The wheel-stopping drone 1 further includes a flight control unit 6 for controlling flight. The flight control unit 6 controls the drone to fly to the lower position side 13b1 of the installation position 13b for stopping the rolling of the vehicle wheels 135, 138 based on the inclination direction of the road surface R where the vehicle 13 is parked.

[0063] For the wheels 135, 138 of the vehicle 13 parked on the inclined road surface R, gravity acts to cause them to roll toward 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 at the lower position side 13b1 of the installation position 13b, the rolling of the wheels 135, 138 can be reliably prevented.

[0064] Also, 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.

[0065] The wheel-stopping drone 1 or the vehicle 13 is equipped 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.

[0066] Also, the flight control unit 6 controls the drone to fly to the installation positions 13b of the non-steerable wheels 135, 138 of the vehicle 13.

[0067] As a result, since the non-steerable wheels 135, 138 always face in the front-rear direction of the vehicle body 134, the wheel-stopping drone 1 can be reliably installed at the installation positions 13b of the wheels 135, 138 regardless of the state of the steering wheel. Furthermore, when the wheel-stopping drone 1 flies based on the flight path stored in the storage unit 61, as long as it is the installation position 13b of the non-steerable wheels 135, 138, the angles of the wheels 135, 138 will not change, so it can be reliably installed at the installation position 13b without changing the flight path.

[0068] Also, the flight control unit 6 controls the drone to fly to the installation positions 13b of both the left and right wheels 135, 138 of the vehicle 13.

[0069] 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 reliably prevent the vehicle 13 from starting to move.

[0070] Further, each rotary wing 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 rotary wing 4 protrudes above the upper surface of the wheel-stopping drone 1 is reduced. 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] Further, the wheel-stopping drone 1 includes a storage unit 61 for storing the flight path along which the wheel-stopping 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-stopping drone 1 to fly between the standby position 13a where the wheel-stopping drone 1 waits and the installation position 13b for preventing the rolling of the vehicle wheel 135, and the wheel-stopping drone 1 can fly automatically along the flight path. Also, although the standby position 13a and the installation position 13b differ for each vehicle 13, by actually storing the flight path along which the wheel-stopping drone 1 has flown, it is possible to store a flight path corresponding to each vehicle 13.

[0074] Further, 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-stopping drone 1 includes a wireless communication unit 8 for receiving the detection signal, and a flight control unit 6 for controlling the 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 a flight path based on the detection signal.

[0076] Accordingly, when the detection unit 132 detects the stop of the drive unit 130 or the actuation of the parking brake unit 131, the wheel stopper drone 1 flies from the standby position 13a to the installation position 13b. Further, when the detection unit 132 detects the start 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. As a result, since an operator such as a driver does not forget to fly the wheel stopper drone 1, it is possible to ensure that the wheel stopper is installed on and removed from the wheel 135.

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

[0078] Accordingly, while the wheel stopper 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 stopper drone 1 through the power supply unit 70.
