There has been a push for autonomous vehicles in the industrial setting to reduce human error and to increase productivity. These vehicles can range from pallet trucks, forklifts and tuggers to industrial cleaners and more. In order for these autonomous vehicles to navigate their surroundings they must be equipped with various pieces of equipment, from sensors to computer hardware. This equipment should be mounted securely to and accurately located on the vehicle they are serving. The mounting process can be destructive to the vehicle when classic forms of fasteners are used, such as nuts and bolts, and it can be difficult to scale the mounting method across a large variety of vehicles with different body styles and sizes.
When using such traditional forms of fasteners, the mounting hardware typically needs to be custom made for the particular vehicle it is on. Customization increases the time and money required to design and manufacture the vehicles. These traditional fasteners can also require large holes to be drilled into the body of the vehicle. In addition to the time and energy it takes to drill these holes, doing so can be risky. For example, if a hole is not drilled correctly the first time, the vehicle can be rendered useless until the hole is repaired or the damaged part is replaced.
Old forms of fasteners can also make a retrofitting process complicated and time consuming, if an existing vehicle is retrofitted to install automation controls. When retrofitting a vehicles with such equipment, it is desirable for the hardware to be mounted quickly, accurately and with ease. The present disclosure provides a quick, easy and accurate way to mount hardware to a wide variety of vehicles without causing damage to those vehicles.
A universal non-destructive adhesive based mounting system is disclosed for the purpose of retrofitting existing industrial vehicles with driverless technology. By using a strong industrial adhesive tape and a universalized mounting system, the autonomous kit can be mounted to any suitable industrial vehicle with ease, accuracy, and without damaging the vehicle, unlike traditional methods. In one example embodiment, the mounting system can include a mounting pad, a protective enclosure and industrial adhesive tape, and can utilize off the shelf sensors, autonomous driving equipment (such as sensors, computers and so forth) and their accompanying mounting hardware. The disclosed mounting process can be installed in the field or in a shop setting or in other suitable manners.
FIGURE A is a diagram of an isometric view of a simple universal adhesive mounting system assembly, in accordance with an example embodiment of the present disclosure. FIGURE A includes vehicle bumper or body 1, industrial adhesive tape 2, mounting pad 3, manufacturer mounting bracket(s) 4, sensor 5, protective enclosure 6 and screws 7.
FIGURE B is a diagram of a side view of a simple universal adhesive mounting system assembly, in accordance with an example embodiment of the present disclosure. The parts shown in FIGURE B are not configured for any specific vehicle or sensor, rather they are simplified versions to illustrate more clearly the assembly and how parts relate to each other.
The vehicle bumper or body 1 can be a rigid and sturdy part of the vehicle. This area can be located where the mounting pad 3 will be adhered using a thin layer of industrial adhesive tape 2. The mounting surface of the mounting pad 3 can be configured to match the contour of the vehicle area it is adhered to, to ensure a better fit and therefore a stronger bond to the vehicle. The back of the mounting pad 3 can be curved concave to fit flush against the convex curve of the vehicle bumper 1. The mounting pad 3 can be modified to ensure proper fit, while all other parts can stay the same. The sensor 5 can be mounted to the mounting pad 3 via its manufacturers mounting bracket(s) 4. The manufactures mounting bracket 4 can then be mounted to the mounting pad 3 using screws 7 fastened into threaded holes in the mounting pad 3. The manufacturer's mounting bracket 4 can be used for simplicity and to lower manufacturing costs, and can also offer sensor adjustment settings that can be useful for accurate calibration. The protective enclosure 6 can fit around the sensor assembly, to protect it from debris and mild impact. The protective enclosure 6 can mount directly to the mounting pad 3 via screws 7 fastened into threaded holes on the mounting pad. The entire assembly can be used to provide a secure non-destructive sensor mount on the surface of a suitable vehicle bumper or body 1.
Enclosure 100 can be configured to allow the corresponding sensor to be mounted to a suitable industrial vehicle when paired with a mounting pad, such as mounting 300 or mounting pad 500 shown herein below. Enclosure 100 can be made from a suitable type of sheet metal, such as aluminum or steel, or other suitable materials. The sheet metal can be easily cut and bent into shape using various manufacturing methods. Enclosure 100 can fit around the sensor and protect it on three sides, front, left, and right. Enclosure 100 can be mounted to a front mounting pad, in the two cases given: mounting pad 300 and mounting pad 500. Enclosure 100 can be mounted to the mounting pad using the mounting tabs 101. Tabs 101 can align with threaded holes located on the front mounting pad 300 or 500. Screws can be used to attach the enclosure 100 to the mounting pad 300 or 500. The sensor sits inside the front enclosure 100 and is then mounted to the front mounting pad using the manufacturer's mounting brackets. These mounting brackets can be adjusted using screws to manipulate the tilt of the sensor. In order to access these adjustment screws, access holes 102 can be provided to the front enclosure 100 to allow the necessary tools to reach the adjustment screws. In order for a user to have a clear view of the sensor, a viewing window 103 can be added to the front enclosure 100. This viewing window 103 is slightly larger than the vision window of the sensor to allow sufficient clearance of the laser.
Mounting pad 300 can be used as an adapter to mount the front sensor, such as a SICK Microscan 3, to the front bumper 701 of the lift truck. This mounting pad can be machined from a suitable material, such as plastics or metals, depending on the sensor and application it is configured for. The curved side 301 of the mounting pad 300 can be configured for the shape of the front bumper 701 of the Crown PC4500 lift truck or in other suitable manners. In this example embodiment, the contour can fit snuggly against the bumper with the adhesive tape between the two surfaces. In order to fit the contour of mounting pad 300 to front bumper 701, measurements of the specific point on the bumper where mounting pad 300 will be installed can be taken with a 3D scanner accompanied with a contour gauge, such as a such as a General Tools 833 Plastic Contour Gauge available from General Tools & Instruments, 75 Seaview Drive, Secaucus, N.J. 07094. From these measurements, a 3D CAD model can be made to reflect the measured contour, or other suitable processes can also or alternatively be used. A prototype can then be created and modified, if needed. Once the proper contour is found, a 3D CAD model of the mounting pad can be generated and the curved surface of the final mounting pad can be manufactured created using computer numerical control machining or other suitable processes.
The threaded mounting holes 302 can be used to attach the protective sensor enclosure 100 and the sensor mounting brackets to the mounting pad using screws. The thickness of the mounting pad can be configured so that the screws being used have a proper thread depth for strength. Other suitable embodiments can also or alternatively be used. Mounting pad 300 can include a planar outer surface having the plurality of threaded mounting holes 302 and a curved inner surface having the curved side, so as to allow the sensor and sensor housing to be attached to a planar surface while allowing the mounting pad 300 to be attached to a non-planar surface.
In one example, mounting pad 300 can be configured to have a contact surface area that corresponds to a weight of a sensor and housing that will be attached to mounting pad 300. In this example embodiment, the weight of the sensor and housing can be used to determine the contact area as a function of the properties of the adhesive material that is used to secure mounting pad 300 to the surface of the vehicle. In this example, mounting pad 300 can have an associated weight rating, where the sensor and housing that are to be used with mounting pad 300 can be matched, to allow the sensor and housing to be secured to mounting pad 300 without damaging the surface of the vehicle while avoiding an excessive loading on mounting pad 300 that could cause the adhesive to fail.

The curved side 401 of the mounting pad 400 can be configured specifically for the shape of the side of the front bumper 701 of the Crown PC4500 lift truck. The contour can be adapted so that it fits against the bumper with the adhesive tape between the two surfaces. The threaded mounting holes 402 can be used to attach the protective sensor enclosure 200, the mounting arms 702, and the sensor mounting brackets to the mounting pad using screws. The thickness of the mounting pad can be configured so that the screws being used have a proper thread depth for strength. Mounting pad 400 can include a planar outer surface having the plurality of threaded mounting holes 402 and a curved inner surface having the curved side, so as to allow the sensor and sensor housing to be attached to a planar surface while allowing the mounting pad 400 to be attached to a non-planar surface.
In one example, mounting pad 400 can be configured to have a contact surface area that corresponds to a weight of a sensor and housing that will be attached to mounting pad 400. In this example embodiment, the weight of the sensor and housing can be used to determine the contact area as a function of the properties of the adhesive material that is used to secure mounting pad 400 to the surface of the vehicle. In this example, mounting pad 400 can have an associated weight rating, where the sensor and housing that are to be used with mounting pad 400 can be matched, to allow the sensor and housing to be secured to mounting pad 400 without damaging the surface of the vehicle while avoiding an excessive loading on mounting pad 400 that could cause the adhesive to fail.
The front mounting pad 500 can be used to be the adapter to mount the front sensor, in this case a SICK Microscan 3, to the front bumper 801 of the lift truck. The mounting pad can be machined from a suitable material, including plastics or metals, depending on the sensor and application it is configured for. The curved side 501 of the mounting pad 500 can be configured specifically for the shape of the front bumper 801 of the Raymond 8510 lift truck or other suitable vehicles or components. The contour can fit against the bumper with the adhesive tape between the two surfaces. The threaded mounting holes 502 can be used to attach the protective sensor enclosure 100 and the sensor mounting brackets to the mounting pad using screws. The thickness of the mounting pad can be configured so that the screws being used have a proper thread depth for strength, and can be associated with different sensor and sensor housings that have an acceptable weight. Mounting pad 500 can include a planar outer surface having the plurality of threaded mounting holes 502 and a curved inner surface having the curved side, so as to allow the sensor and sensor housing to be attached to a planar surface while allowing the mounting pad 500 to be attached to a non-planar surface.
