Abstract

Autonomous vehicle charging station housing that is portable. When the housing's pivotable door is open, the vehicle navigates into the housing. The vehicle is automatically charged by an inductive charger on a charging dock on the floor once the door is closed. The door also acts as a ramp for the vehicle to climb up into the housing. Housing has compressed air for cleaning the vehicle. Housing is positively pressurised to prevent entry of dust from the outside. Tapered barriers with rollers on the floor guide the vehicle into a charging position.

Description

AUTONOMOUS VEHICLE CHARGING STATION WITH CLOSABLE HOUSING

TECHNICAL FIELD

[0001] The present invention relates to autonomous vehicle charging stations, systems and methods. In particular, although not exclusively, the present invention relates to an autonomous vehicle charging station for charging unmanned robotic vehicles.

BACKGROUND

[0002] Autonomous vehicles are becoming increasingly prevalent in both residential and commercial/industrial landscapes. These autonomous vehicles have diverse applications, from performing tasks, such as cleaning, to surveillance and data capture, and operate in a range of environments, including agricultural, manufacturing, mining, and transport applications. The use of autonomous vehicles to perform tasks may improve operational efficiency and/or personnel safety.

[0003] Typically, autonomous vehicles are battery powered, alleviating the need for fuel or powered tethers. As a result, such autonomous vehicles typically need to be recharged regularly. This is typically accomplished by connecting the autonomous vehicle to a stationary power source, or by using a docking station.

[0004] Docking stations are useful in that they allow autonomous vehicles to charge themselves, without human interaction. Docking stations typically comprise a charging element including electrical contacts which engage with corresponding electrical contacts of the vehicle. This requires the autonomous vehicle to position itself relative to the charging element such that the electrical contacts of the docking station contact corresponding electrical contacts of the autonomous vehicle are aligned.

[0005] A problem with the use of such docking stations is that they are not well suited to rough environments, e.g. in a mine or similar environment. For example, in rough or rocky terrain, it may be difficult (or impossible) to properly align the electrical contacts of the autonomous vehicle with corresponding electrical contacts of the docking station.

[0006] Another problem with the use of such docking stations is that they are not well suited to harsh environments. For example, in harsh dusty and dirty environments, the electrical contacts of the docking station may become covered with dirt or dust, requiring regular cleaning and maintenance. Similarly, electrical contacts of the autonomous vehicle, as well as sensors and other components of the autonomous vehicle, may also require regular cleaning, taking away some of the benefits of using autonomous vehicles. [0007] A further problem associated with the use of such docking stations is that the autonomous vehicle is prone to damage during charging, especially where the autonomous vehicle is charged in harsh environments. The autonomous vehicle may become damaged via exposure to environmental elements which can compromise both vehicle integrity and charging infrastructure, in turn escalating maintenance demands and operational costs. Similarly, the autonomous vehicle may even be maliciously damaged if sitting for long periods unattended.

[0008] As such, there is clearly a need for an improved autonomous vehicle charging stations, systems and methods.

[0009] It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

SUMMARY OF INVENTION

[0010] Embodiments of the present invention provide autonomous vehicle charging stations, systems and methods, which may at least partially address one or more of the problems or deficiencies mentioned above or which may provide the public with a useful or commercial choice.

[0011] With the foregoing in view, the present invention in a first aspect, resides broadly in an autonomous vehicle charging station comprising: a housing configurable between an open configuration, where the housing is open to enable an autonomous vehicle to navigate to an inside of the housing, and a closed configuration, where the housing is closed; and a charging dock, associated with the inside of the housing, and configured to enable the autonomous vehicle to autonomously dock thereto using autonomous vehicular navigation and automatically charge the autonomous vehicle while the autonomous vehicle is positioned at the inside of the housing and the housing in the closed configuration.

[0012] In a second aspect, the present invention resides broadly in a method of charging an autonomous vehicle in a housing, the method including: opening the housing, to provide access to an inside of the housing to the autonomous vehicle; autonomously navigating the autonomous vehicle to the inside of the housing and dock with a charging dock using autonomous vehicular navigation; closing the housing when the autonomous vehicle is positioned at the inside of the housing; and automatically charging the autonomous vehicle, using the charging dock associated with the inside of the housing, while the autonomous vehicle is positioned at the inside of the housing and the housing in the closed configuration.

DETAILED DESCRIPTION

[00169] Figure 1 illustrates an autonomous vehicle charging system 100, according to an embodiment of the present invention. [00170] The autonomous vehicle charging system 100 includes an autonomous vehicle in the form of an industrial robot 105, and an autonomous vehicle charging station 110. The autonomous vehicle charging station 110 is configured to receive and charge the industrial robot 105.

[00171] The autonomous vehicle charging station 110 includes a housing 110a, which is configurable between an open configuration, as illustrated in Figure 1 , to enable the industrial robot 105 to navigate to an inside 115 of the housing 110a, and a closed configuration, where the housing 110a is closed. The autonomous vehicle charging station 110 includes a charging dock and charging device in the housing 110a, configured to charge the industrial robot 105 while in the housing 110a.

[00172] The industrial robot 105 is battery powered and includes a plurality of wheels 120 that drive the industrial robot 105 using one or more motors. The plurality of wheels 120 are be located on either side of the industrial robot 105.

[00173] The industrial robot 105 further includes sensors in the form of a camera 125 and a distance sensor 130. The skilled addressee will readily appreciate, however, that any suitable type, number or arrangement of sensors may be used. Such configuration enables the industrial robot 105 to autonomously navigate and capture data from different places as it navigates.

[00174] The industrial robot 105 includes an autonomous vehicle data store 135, to store data from the camera 125 and distance sensor 130 as it is captured, as well as other data relating to the environment of the industrial robot 105, the interactions of the industrial robot 105, and the positioning of the industrial robot 105. This information may then be used for later analysis of the site.

[00175] The industrial robot 105 includes a communications system in the form of a wireless transceiver 140. The industrial robot 105 communicates wirelessly with the autonomous vehicle charging station 110 using the wireless transceiver 140. The industrial robot 105 may transmit commands (e.g. a command to open the autonomous vehicle charging station 110), or data captured by the industrial robot 105, e.g. from the autonomous vehicle data store 135.

[00176] As outline above, the industrial robot 105 is battery operated. As the industrial robot 105 operates, the battery depletes. The industrial robot 105 monitors a charge level of the battery, and at a defined charge level, a pre-defined time, upon receiving a command, or when one or more tasks have been completed, the industrial robot 105 navigates to the autonomous vehicle charging station 110 for charging. [00177] Now turning back to the autonomous vehicle charging station 110, the housing 110a defines an enclosed area on an inside 115 thereof, for receiving the industrial robot 105 for charging.

[00178] The housing 110a comprise a floor, a roof, and sidewalls defining a substantially cuboidal shape. The floor, roof, and sidewalls are defined by panels 145 supported by a frame.

[00179] As illustrated, the roof of the housing 110a is defined by three panels 145. The three panels 145 form a substantially convex roof.

[00180] The housing 110a includes a plurality of frame members, in this instance, box sections. Each of the box sections are welded together to form a substantial cuboidal frame. The panels 145 are fixed to the frame using a plurality of screws.

[00181] The housing 110a is elevated from a ground surface by support members 150 defining a frame under the housing 110a.

[00182] The support members 150 in turn define receiving portions, shaped and sized to receive pallet forks or the like, to facilitate movement of the autonomous vehicle charging station 110.

[00183] Prior to use, the industrial robot 105 may be stored inside 115 the housing 110a. The autonomous vehicle charging station 110 (with the industrial robot 105 in the housing 110 thereof) may be transported to a site, such as a mine site, e.g. using a pallet fork received in the receiving portions.

[00184] To assist with the safe transport of the autonomous vehicle charging station 110 and industrial robot 105, the inside 115 of the housing 110a and the industrial robot 105 each include anchor points (not illustrated) to receive a rope or like tether to secure the industrial robot 105 in the housing 110.

[00185] The housing 110a includes a door 155. The door 155 is formed by a panel and a plurality of box sections, much like the sidewalls. The door 155 is pivotally attached to a base of the housing 110a via a hinge 160. In use, the door 155 pivots about a pivot point between to open and close. The door 155 pivots around a horizontal axis. When open, the door 155 defines a ramp extending down toward a ground surface.

[00186] In use, the industrial robot 105 travels across the door 155, which functions as a ramp, to the inside 115 of the housing 110a. [00187] The industrial robot 105 is then positioned entirely in the inside 115 of the housing 110a. When the industrial robot 105 is positioned inside the housing 110a, the door 155 is raised, to cause the autonomous vehicle charging station 110 to move to the closed configuration.

[00188] The housing 110a includes sensors in the form of a distance sensor 170 and a camera 175. The sensors 170, 175 are positioned on the roof of the housing 110a and are configured to generate data relating to the surrounds of the housing 110a. In use, it is envisaged that the sensors 170, 175 generate data pertaining to the position of the industrial robot 105.

[00189] The autonomous vehicle charging station 110 further includes a controller (not illustrated). The controller is associated with a strut actuator 165 coupled to the door 155. The controller and strut actuator 165 control the opening and closing of the door 155. The controller is configured process data relating to the surrounds of the housing 110a received by the sensors 170,175 and cause the strut actuator 165 to open the door 155, e.g. based on a location of the industrial robot 105. Alternatively, or additionally, the controller may cause the strut actuator 165 to open the door 155 upon receipt of a command.

[00190] In use, it is envisaged that the sensors 170, 175 will capture data and the controller will process the captured data and determine a position of an industrial robot 105. If the industrial robot is determined to be in proximity to the housing 110a, the controller may cause the strut actuator 165 to open the door 155. The industrial robot 105 then travels across the door 155 (which functions as a ramp) and into the inside 115 of the housing 110a. The door 155 is then closed.

[00191] Figure 2 illustrates a front view of the autonomous vehicle charging station 110 in the open configuration, according to an embodiment of the present invention. Figure 3 illustrates a top cut away view of the autonomous vehicle charging station 110, cut away just under the roof and in the closed configuration, according to an embodiment of the present invention.

[00192] As illustrated in Figures 2 and 3, the inside 115 of the housing 110a includes guides in the form of rollers 205, configured to guide the industrial robot 105 to a charging dock and charging device in the form of an inductive charger 210. The inductive charger 210 is positioned at a center of the floor of the housing 110a.

[00193] The guides each comprises three rollers 205 positioned on opposing side walls of the housing 110a. As best illustrated in Figured 3, the rollers 205 are tapered such that they are closer to each other towards the rear of the housing 110a, to thereby guide the industrial robot 105 towards a centre of the housing 110a, as the industrial robot 105 enters the housing 105, to align the industrial robot 105 with the inductive charger.

[00194] The rollers 205 are positioned adjacent a lowermost portion of the opposing side walls. In use, the rollers 205 are configured to roll in a direction towards the floor of the housing 110a to prevent the industrial robot 105 from climbing the walls of the housing 110a. In short, the wheels of the industrial robot 105 are unable to engage with the side walls, as the side walls are blocked by the rollers 205. Furthermore, the rollers 205 prevent the industrial robot 105 from climbing, even if engaged by a wheel of the robot 105, as the rollers 205 roll downwards, causing the wheel (and thus robot 105) to drop, rather than providing a surface with which the wheel may engage.

[00195] The housing 110a includes a stopper in the form of a bumper 305, positioned on a wall opposite the door 155 and is configured to stop the industrial robot 105 from contacting the wall opposite the door 155 upon entry to the inside of the housing 110a. The rollers 205 and bumper 305 function to position the industrial robot at the inductive charger 210.

[00196] The inside 115 of the housing further includes one or more sensors (not illustrated). The one or more sensors on the inside of the housing may include image sensors, such as cameras, and may be similar to the sensors 170, 175 positioned on the outside of the housing 110a. The one or more sensors on the inside 115 of the housing 110a may further include a particle sensor.

[00197] The one or more sensors are configured to generate data relating to the inside 115 of the housing and/or the industrial robot 105 therein. The one or more sensors may generate data relating to the volume of debris/particulate matter inside the housing 110a.

[00198] Data from the one or more sensors is stored in a housing data store, which may comprise a memory. Data from the housing data store may further be communicated to one or more external systems using a communications system, outlined in further detail below.

[00199] Figure 4 illustrates an upper perspective view of the autonomous vehicle charging station 110 in a closed configuration, according to an embodiment of the present invention.

[00200] Figure 5 illustrates a rear view of the autonomous vehicle charging station 110 according to an embodiment of the present invention.

[00201] The housing 110a is configured to receive power from an electrical power source. In use, the autonomous vehicle charging station 110 is powered using the power port 505. [00202] The autonomous vehicle charging station 110 further includes a cable rack 525, configured to store cables such as cables associated with the power port 505 (i.e. power supply cables) and/or hoses, such as compressed air hoses.

[00203] The autonomous vehicle charging station 110 includes a wireless communications system, including wireless transceiver 405. The wireless communications system enables the autonomous vehicle charging station 110 to communicate wirelessly with the industrial robot 105 and one or more remote systems, including a remote server and database.

[00204] In use, the communications system receives communications from the industrial robot 105, e.g. containing captured sensor data, data pertaining to the charge of the industrial robot 105 and/or the condition and cleanliness of the industrial robot 105.

[00205] The communications system then forwards the communications to the remote server, to be saved on the database, for access by personnel and/or other systems, e.g. remotely using the Internet. Furthermore, the communications system may process the communications, and send alerts or the like to personnel, for example. Finally, the data received from the industrial robot 105 may be saved at the autonomous vehicle charging station 110, for later use.

[00206] Personnel may interact with the communications system and/or server via a computing device to obtain data shared from the industrial robot 105 and/or directly from the autonomous vehicle charging station 110.

[00207] The autonomous vehicle charging station 110 includes a display (not illustrated) on a sidewall thereof, with which personnel may interact using controls and/or a user interface thereof. The display may display information recorded by the sensors 170,175 of the autonomous vehicle charging station 110 and the industrial robot 105 therein. Furthermore, the display may be used to configure the autonomous vehicle charging station 110.

[00208] In addition to charging the industrial robot 105, the autonomous vehicle charging station 110 may clean the industrial robot 105.

[00209] Figure 6 illustrates a partially transparent upper perspective view of the autonomous vehicle charging station 110, illustrating a cleaning unit 600 thereof and in the closed configuration, according to an embodiment of the present invention.

[00210] Figure 7 illustrates an upper perspective view of the cleaning unit 600 (in isolation), according to an embodiment of the present invention. [00211] The cleaning unit 600 is positioned primarily within a ceiling portion of the housing 110a and is configured to clean the industrial robot 105. In particular, the cleaning unit includes an inlet 605, configured to receive compressed air from a compressed air source, and a plurality of outlets, including nozzles 610, air knives 615 and a positive pressure outlet 620.

[00212] The nozzles 610 are configured to clean sensors of the industrial robot 105, such as cameras, and the air knives 615 are configured to clean a payload or body of the autonomous vehicle 105.

[00213] The positive pressure outlet 620, is configured to provide positive pressure to the inside of the housing 110a. Advantageously, constant supply of fluid to the inside of the housing 110 assists in preventing dust from entering the housing 110a through small gaps, for example.

[00214] The cleaning unit 600 further includes a flow controller 625, configurable to selectively control flow to one or more outlets of the plurality of outlets. Such configuration enables the plurality of outlets to be selectively operated.

[00215] The cleaning system further includes a pipeline 630, coupling the inlet 605 and the outlets.

[00216] As the industrial robot 105 navigates inside the housing 110a, it passes the air knives 615, which clean the industrial robot 105 using the compressed from the air knives 615. The air knives 615 may be directed towards the opening of the housing 110a, blowing debris and/or particulate from the industrial robot 105 out from the housing 110a.

[00217] While not illustrated, the inside 115 of the housing 110a may include a waste storage system. The waste storage system may comprise a container or the like for receiving waste. In use, debris and/or particulate matter is cleaned from the industrial robot 105 and settles in the waste storage system. The debris and/or particulate matter is then expelled from the waste storage system to an outside of the housing 110a when the housing 110a is in the open configuration. The air knives 615 may be directed towards the opening for such purpose. Alternatively, the debris and/or particulate matter may be expelled from the waste storage system in other manners, including through mechanical expulsion.

[00218] Again, while not illustrated, the cleaning system may include an external cleaning system, for cleaning outside of the housing. For example, the external cleaning system may clean the ground surface adjacent to the housing. In such case, autonomous vehicle charging system may include one or more blowers and/or sweepers configured to move dust and/or debris away from the ground adjacent the housing. Similarly, the external cleaning system may clean the autonomous vehicle while outside of the housing.

[00219] The skilled addressee will readily appreciate that the autonomous vehicle charging system 100 may be used in any environment, and with autonomous vehicles or robots for any purpose. The autonomous vehicle charging system 100 is, however, particularly suited for monitoring an industrial site, such as a mine site.

[00220] Advantageously, embodiments of the present invention described above enable an autonomous vehicle to selectively access the inside of the housing of the charging station when in the open configuration and provide protection to the charging dock and device while the housing is in the closed configuration. Furthermore, by providing the charging dock and charging device in the housing, the autonomous vehicle may charge in a protected environment. Yet further again, by providing the charging dock in the housing, the autonomous vehicle may more easily align with the charging dock, without being reliant on the quality of the ground surface. Furthermore, charging the autonomous vehicle while in the housing may prevent disruptions to charging of the autonomous vehicle such as by accidental disconnection of the charging dock.

[00221] In the present specification and claims (if any), the word ‘comprising’ and its derivatives including ‘comprises’ and ‘comprise’ include each of the stated integers but does not exclude the inclusion of one or more further integers.

[00222] Reference throughout this specification to ‘one embodiment’ or ‘an embodiment’ means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases ‘in one embodiment’ or ‘in an embodiment’ in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more combinations.

[00223] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect.
