Description

SENSOR MOUNTING SYSTEM
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Application 62/705,666, filed 9 July 2020.
TECHNICAL FIELD
[0002] The present invention relates to mounting systems for sensors and, more particularly, to mounting systems that can be deployed in and/or on a variety of platforms to provide physical and electrical interfaces for the sensors to be deployed in or on said platforms.
BACKGROUND
[0003] Unmanned vehicles, whether for use in airborne, surface, or subsurface applications, are typically deployed in conjunction with one or more sensors or sensor modules. The sensor modules may be designed to collect data concerning an environment into which the unmanned vehicle is released as well as concerning the unmanned vehicle itself. The same is true for sensor modules associated with manned vehicles.
[0004] Although manned and unmanned vehicles can be employed in connection with a variety of different missions, it is often the case that a particular vehicle will be “purpose-built.” That is, individual manned and unmanned vehicles are often fitted with only a single sensor module such as a camera, LiDAR system, thermal imaging system, microphone, infrared sensor, magnetometer, multispectral sensor, radiation sensor, humidity sensor, velometer, temperature sensor, gas sensor, chemical sensor, etc. Even where such sensor modules are replaceable, it is often the case that only like kinds of the sensor modules can be fitted to the manned or unmanned vehicle because specialized mechanical and/or electrical mounting systems of the manned or unmanned vehicle are designed to accommodate only that kind of the sensor module. Moreover, current sensor mounting systems are often mechanically complex and/or require use of tools to mount/unmount the sensors or the sensor module from the manned or unmanned vehicle.
SUMMARY
[0005] In various embodiments, a sensor mounting system configured in accordance with the present invention allows for secure mechanical and electrical mounting of sensors to vehicles while at the same time accommodating speedy unmounting/mounting of the sensors in or on the vehicles. Additionally, in some embodiments the invention provides an apparatus for mounting sensors or sensor modules, which can be deployed on various kinds of vehicles.
[0006] Accordingly, one embodiment of the invention provides a sensor mounting system having a mounting base installed on a surface of an object using at least one mounting bracket and a retractable platform attached to the mounting base via one or more locking mechanisms. The retractable platform is configured to house one or more sensors. Any one or more of a plurality of locking mechanisms may be employed, for example a rail and slide mount, a ledge and lock mechanism, and threaded mount. An electronic connection system associated with the retractable platform and configured to enable data communication between the one or more sensors of the retractable platform and the object is included.

[0046] The following description provides exemplary embodiments only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the following description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing one or more exemplary embodiments. Contemplated are various changes that may be made in the function and arrangement of elements without departing from the spirit and scope of the subject matter disclosed as set forth in the appended claims.
[0047] Described herein are sensor mounting systems for installing one or more sensors on an object and providing physical and electrical interfaces for the one or more sensors to be installed on the object. The object may correspond to a vehicle (such as a manned vehicle or an unmanned vehicle), stationary installation, human-wearable article, or animal-wearable article. The one or more sensors may include but are not limited to a camera, a radar, a LiDAR sensor, a microphone, an infrared sensor, a magnetometer, a multispectral sensor, a radiation sensor, one or more weather sensors (such as a humidity sensor, a velometer, a temperature sensor, and the like), a gas sensor, a chemical sensor, and a global navigation satellite system (GNSS). In one embodiment, a sensor module having one or a combination of the aforesaid sensors is installed on the surface of the object. In a further embodiment, in addition to or replacing the one or more sensors, non-sensors such as a delivery pod can be installed on the sensor mounting system.
[0048] Some embodiments are based on a recognition that while proliferation of manned and unmanned vehicles affords significant opportunities for installing a variety of different kinds of sensor modules, an inability for vehicle owners/operators to rapidly swap out installed sensor modules in cases of sensor malfunction and/or new vehicle missions has led to increased costs (e.g., when multiple vehicles with redundant and/or different sensor modules must be kept on hand and/or installed) and complexities. To that end, some embodiments provide a sensor mounting system that allows for secure mechanical and electrical mounting of sensor modules to vehicles while at the same time accommodating speedy unmounting/mounting of the sensor modules in or on the vehicles.
[0049] For purposes of explanation, examples of the sensor mounting systems will be described with reference to an unmanned aerial vehicle (UAV) and a LiDAR sensor. LiDAR sensors are used to measure terrain, tree cover, infrastructure condition, and the like. However, LiDAR sensors are quite expensive and using a LiDAR sensor in multiple scanning devices requires services of a skilled technician to mount/unmount the sensor, if it is even possible. In accordance with embodiments of the present invention, the LiDAR sensors may be securely mounted on the UAV in a manner that provides both physical and electrical connectivity while also permitting rapid and uncomplicated unmounting. Once unmounted, the LiDAR sensor may be mounted on another vehicle or the object, using a similar mounting arrangement. The senor mounting systems described herein may be employed in connection with human-worn articles such as backpacks, harnesses, etc.; animal-worn articles such as saddlebags; airborne, surface, and sub-surface vehicles; and/or stationary installations such as tripods, equatorial mounts, sidereal mounts, etc.
[0050] FIGs. 1 and 2 collectively show a sensor mounting system for mounting a LiDAR sensor 104 on a UAV 113, according to an embodiment of the invention. The UAV 113 includes a main body 102 and four motors 108 deployed at ends of respective motor arms 105, 110 and connected to the main body 102 via a pair of extension arms 109, 111. Further, the UAV 113 includes ancillary components such as a communication antenna 106. The sensor mounting system includes a mounting base installed on a surface of the object (e.g., UAV 113), using at least one mounting bracket. The UAV 113 includes a mounting enclosure 112 (also referred to as the mounting base) configured to retain a retractable platform. The retractable platform is attachable to the mounting base via one or more locking mechanisms. Further, the retractable platform is configured to house the one or more sensors. For example, the LiDAR sensor 104 and its GPS antenna 107 are carried in a retractable platform 117 via rails 103. The one or more locking mechanisms may be any of a rail and slide mount, a ledge and lock mechanism, and/or a threaded mount.
[0051] As further illustrated in FIG. 2, a mounting handle 101 may be used to guide complementary rails 116 on the retractable platform 117 to engage with the rails 103 of the mounting enclosure 112 when mounting the LiDAR sensor 104 to the UAV 113. When so mounted, an electronic connection system 114 associated with the retractable platform 117 enables data communication between the one or more sensors of the retractable platform 117, and the vehicle (i.e., UAV 113). Additionally, in an alternate embodiment, the electronic connection system 114 provides power as well as serial and network communications to the LiDAR sensor 104 from the UAV 113.
[0052] To that end, the rails 116 of the LiDAR sensor 104 (and their complements 103 on the UAV 113) are an example of the sensor mounting system of the present invention that provides a user interchangeability of vehicles/sensor modules for collection of data and other missions. By incorporating such a mount, the user can expect similar mechanical and electrical integration, regardless of the vehicle/equipment on which the sensor module is mounted. Further, the mount, which is a physical connection between the retractable platform and the vehicle, is distinguished from the electrical connection therebetween.
[0053] FIGs. 3-7 show exemplary rail and slide mounts for attaching a retractable platform 1003 to a mounting base 1002 of a vehicle 1001, according to some embodiments of the invention. FIG. 3 shows the rail and slide mount with one or more accessory lock mechanisms, according to an embodiment of the invention. The mounting base 1002 is installed on a surface of the vehicle 1001, using at least one mounting bracket. According to an embodiment, the mounting base 1002 is installed on top surface of the vehicle 1001. The rail and slide mount includes a rail 1005 on the mounting base 1002 and a slide 1004 on the retractable platform 1003. The retractable platform 1003 is attached to the mounting base 1002 by a longitudinal insertion of the slide 1004 on the retractable platform 1003 into the rail 1005 on the mounting base 1002 to attach the retractable platform 1003 with the vehicle 1001. [0054] Further, the rail and slide mount includes the one or more accessory lock mechanisms to secure the slide 1004 into the rail 1005. The one or more accessory lock mechanisms correspond to a pin and or an adjustable screw 1007 that can attach the retractable platform 1003 to the mounting base 1002, a detent 1006 on the rail 1005 of the mounting base, a mechanical latch 1008, a latch-and-teeth locking mechanism, a hook-and- loop attachment of the retractable platform 1003 to the mounting base 1002, and a pin-and- detent locking mechanism. The adjustable screw and or a pin 1007 is configured to stop the slide 1004 from moving out of the rail 1005. The latch-and-teeth mechanism includes the mechanical latch 1008 and teeth 1009 combinedly configured to hold the slide 1004 within the rail 1005. The slide 1004 and the rail 1005 combination correspond to a dovetail insert. In an alternate embodiment, a C-channel insert is used in the rail and slide mount.
[0055] FIG. 4 shows an example of a C-channel insert which may be used in place of the dovetail insert for the rail and slide mount shown in FIG. 3, according to some embodiments of the invention. The C-channel insert includes C shaped space 1101 in the retractable platform 1003 that can receive a C shaped slide 1102 of the mounting base 1002. Additionally, the rail 1005 and slide 1004 can be of complex geometries to limit degrees of freedom, so as to secure the slide 1004 into the rail 1005. Examples of the complex geometries include such geometries as squares, stars, triangles, points, hexagons, etc.
[0056] In FIG. 3, the rail 1005 is illustrated as a part of the vehicle 1001 and the slide 1004 as a part of the retractable platform 1003, however, the reverse is also possible in which the retractable platform 1003 includes the rail 1005 and the mounting base 1002 of vehicle 1001 includes the slide 1004. Within such a mount, orientation of the rail and slide may be vertical, horizontal, or askew. Additionally, though FIG. 3 depicts a straight rail and slide mount, a bend to the rail, forming a circular implementation or twist of the rail to constitute a corkscrew implementation may be provided.
[0057] Some embodiments are based on a realization that the rail and slide mount may include multiple slides on the retractable platform 1003 and corresponding multiple rails on the mounting base 1002 for effective secure of the retractable platform 1003 with the mounting base 1002. FIG. 5 shows a retractable platform 1203 having two slides 1201 and a mounting base 1204 having corresponding two rails 1202, according to an embodiment of the invention. The retractable platform 1203 is attached to the mounting base 1204 by a longitudinal insertion of the two slides 1201 on the retractable platform 1203 into the corresponding two rails 1202 on the mounting base 1204 to attach the retractable platform 1203 with the vehicle. Additionally, a rail can include a self-centering geometry across length of the design with a slight reduction of the rail’s inside dimension to align the retractable platform 1203 into the electrical connection on the vehicle.
[0058] FIG. 6 shows an example of a covering 1303 of a rail 1302 and slide 1301 to increase durability of the rail and slide mount, according to an embodiment of the invention. For such a covering 1303, a flexible material may be used.
[0059] FIG. 7 shows a telescopic cover 1401 for the rail and slide mount, according to an embodiment of the invention. The telescopic cover 1401 extends when a restorable platform 1403 and a mounting base 1402 are not mated, and retracts when the restorable platform 1403 and the mounting base 1402 are attached to each other.
[0060] FIGs. 8-13 show exemplary ledge and lock mechanisms, according to some embodiments of the invention. In FIG. 8, the retractable platform 2001 is secured to a vehicle 2002 utilizing a ledge 2003 on which the retractable platform 2001 is placed. The ledge 2003 can provide initial limitation of the degrees of freedom through geometric shapes and/or raised edges 2004. The ledge and lock mechanism further includes one or more accessory lock mechanisms configured to secure the retractable platform on the ledge. For example, a screw 2005 attaching the retractable platform 2001 to the ledge 2003, or a pin 2006 to stop the retractable platform 2001 from moving out of the ledge 2003 may be used.
[0061] FIG. 9 shows a latch-and-teeth locking mechanism 2101 for the ledge and lock mechanism to hold the retractable platform 2001 within ledge 2102, according to some embodiments of the invention. Further, a mechanical latch 2101 configured to retain the retractable platform 2001 in place on the ledge 2102 is also employed. Furthermore, the ledge and lock mechanism includes a pin-and-detent locking mechanism 2104 and a press- fit ball-in-socket to secure the retractable platform 2001 to the ledge 2103, and a flexible- band 2105 to secure the retractable platform 2001 to the vehicle. While FIGs. 8 and 9 show implementations of a flat straight ledge, the ledge and lock mechanism may incorporate a circular ledge, a triangular ledge, a wavy ledge, a mountain-shaped ledge, a gear teeth ledge, or any other complex geometry that acts as a ledge by which the retractable platform is affixed to the vehicle.
[0062] FIG. 10 shows the ledge and lock mechanism using an adhesive, according to an embodiment of the invention. A chemical adhesive 2202 is applied to a ledge 2201 in order to secure retractable platform 2200 to a vehicle 2203 or a mounting base of the vehicle 2203. To that end, the retractable platform 2200 may be adhesively attached to the ledge of the mounting base.
[0063] FIG. 11 shows a hook and loop attachment for the ledge and lock mechanism, according to an embodiment of the invention. A hook 2304 and loop 2303 is used to secure a retractable platform 2300 to a ledge 2302 on a mounting base of a vehicle 2301. A hook and loop attachment utilizing steel or other metals can act as a vibration damping between the vehicle 2301 and the retractable platform 2300.
[0064] FIG. 12 shows a retractable platform 2401 attached to a mounting base of a vehicle 2400, using a combination of the rail and slide mount, and the ledge and lock mechanism, according to an embodiment of the invention.
