Description
BACKGROUND
Field

This disclosure relates to systems and methods for flat towing a vehicle, and more particularly to adapters for coupling a tow bar to a vehicle frame.


Description of the Related Art

Many vacationers and travelers like to tour and sightsee in their cars or vehicles and oftentimes buy or rent a motorhome or a recreational vehicle (RV) to enhance their comfort and enjoyment. For extended vacations, the motorhome or the RV may be hooked up to tow another vehicle (e.g., their car or vehicle, a cargo trailer, a smaller vehicle, or a sports utility vehicle (SUV)). When parked, the vehicle being towed can be disconnected from the towing vehicle to allow the vacationers and travelers to take excursions or drive into town and have a more mobile, fuel efficient, and compact vehicle while the motorhome or the RV is parked at a campground, for example.


In many situations, the vehicle being towed (sometimes referred to as a towed vehicle) is being flat-towed (i.e., all wheels are on the ground). In order to couple the towed vehicle to the towing vehicle in the first place, it is necessary to install an aftermarket flat tow base plate onto the vehicle front bumper, which can be time consuming, complex, and costly. Often, these aftermarket flat tow base plates require that several front-end components of the vehicle be removed in order to access the attachment points of the flat tow base plates to the vehicle. Therefore, what is needed is a vehicle that has a built-in tow bar attachment point that requires minimal time and effort for attaching a tow bar when it is desired to flat tow the vehicle.

DETAILED DESCRIPTION

A vehicle of the present disclosure is configured to be flat towed. The vehicle includes a body structure including a front side member support having an end portion and a bumper beam mounted to the end portion. The body structure further includes a front side member plate mounted to the end portion of the front side member support. In some embodiments, a nut fastener is attached to the front side member plate (e.g., via a weld or the like). A towing bracket adapter can be threadingly (e.g., removably) coupled to the nut fastener. A tow bar base plate can be mounted to the nut fastener via one or more fasteners. In other embodiments, a towing bracket adapter is mounted directly to the front side member plate (i.e., without the nut fastener). For example, the towing bracket adapter can be permanently mounted to the front side member plate via a weld. The towing bracket adapter is mounted behind the front fascia of the vehicle.


Particular embodiments of the subject matter described in this disclosure may be implemented to realize one or more of the following advantages. A vehicle of the present disclosure eliminates the need for users to install aftermarket flat tow attachment means onto the vehicle front bumper when the user wants to flat tow their vehicle. Moreover, tow bar attachment assemblies described herein provide aesthetically pleasing (e.g., due to being concealed by a front vehicle panel) attachment points while also providing ease of access to the attachment points without having to perform disassembly of any major vehicle components.



FIG. 1 illustrates an exemplary tow bar 1 coupled between a towing vehicle 5 (e.g., a motorhome, a recreational vehicle (RV), a sport utility vehicle (SUV), a truck, or the like) and a towed vehicle 6 (e.g., a SUV), where the towed vehicle 6 is being flat towed (i.e., all wheels are on the ground). The towing vehicle 5 and the towed vehicle 6 can be a conveyance capable of transporting a person, an object, or a permanently or temporarily affixed apparatus. The towing vehicle 5 and the towed vehicle 6 can be a self-propelled wheeled conveyance, such as a motorhome or a recreational vehicle (RV), a car, a sports utility vehicle, a truck, a bus, a van, a trailer or other motor, battery, or fuel cell driven vehicle. For example, the towing vehicle 5 and the towed vehicle 6 can be an electric vehicle, a hybrid vehicle, a hydrogen fuel cell vehicle, a plug-in hybrid vehicle or any other type of vehicle that has an engine, a fuel cell stack, a motor and/or a generator. Other examples of vehicles include bicycles, trains, planes, or boats, and any other form of conveyance that is capable of transportation. The towing vehicle 5 and the towed vehicle 6 can be semi-autonomous or autonomous. That is, the towing vehicle 5 and the towed vehicle 6 can be self-maneuvering and navigate without human input.


As is seen in the exemplary illustrated embodiment, the tow bar 1 generally includes a shank 10 that is sized and shaped to be inserted into a receiver 2 of a towing hitch 3 mounted on the towing vehicle 5. A proximal end of the shank 10 is shaped and sized to releasably connect to (e.g., insert into) the receiver 2 of the towing hitch 3. The receiver 2 can be a hollow rectangular tube. The inner dimension of the receiver 2 can be slightly larger than the outer dimension of the shank 10 so as to allow the shank 10 to be slidably inserted into and received by the receiver 2. The shank 10 can be inserted into the hitch receiver 2 and held in the receiver 2 by way of a locking pin (not shown) inserted into aligned holes, respectively, located in the lateral sides of the shank 10 and the receiver 2. For example, a hole 9 is illustrated in a lateral side of the receiver 2 which can align with a similar hole in the shank 10 whereby a locking pin can be inserted therethrough.


The tow bar 1 further includes a pair of swing arms 43 configured to be connected to towing brackets 4 of the towed vehicle 6. Accordingly, the tow bar 1 is configured for connecting the towing hitch 3 on the towing vehicle 5 to the towed vehicle 6 having two towing brackets 4. FIG. 1 shows the tow bar 1 with the shank 10 of the tow bar 1 inserted into the receiver 2 and distal ends 42 of the swing arms 43 are connected to the towing brackets 4 on the towed vehicle 6.


In practical use, the towing vehicle 5 will normally be situated upon a roadway surface considered horizontal in reference to the towing vehicle 5. Thus, the directional terms “vertical” and “horizontal” and the like are used to describe the tow bar 1 and its components with respect to the orientation illustrated in FIG. 1 and are employed merely for the purposes of clarity and illustration. In the orientation shown in FIG. 1, the shank 10 projects “horizontally” out from the receiver 2. One or more pivot couplers (e.g., pivot coupler 20, pivot coupler 30, and/or pivot coupler 40) connects a distal end 15 of the shank 10 to proximal ends of the swing arms 43. The directional terms “proximal” and “distal” and the like are used herein with respect to the described tow bar 1 to refer to positions and locations on the tow bar 1 relative to the receiver 2 when holding the tow bar 1.


In various embodiments, each swing arm 43 can be extendable and can be locked to hold the swing arm at its extended length. The distal end 42 of each swing arm 43 can include a coupler 66 for connection to one of the towing brackets 4 on the towed vehicle 6.



FIG. 2A illustrates a perspective view of an example vehicle 200 configured to be flat towed. The vehicle 200 includes a pair of towing brackets 210 installed to the body structure or frame thereof, as described in greater detail below. Only one towing bracket 210 is illustrated in FIG. 2A, though it should be understood that a pair of towing brackets 210 is provided at the front of the vehicle 200, similar to the towed vehicle 6 of FIG. 1. The vehicle 200 can include a front bumper cover 202 disposed at a front end thereof and defining an outer aerodynamic surface 204 of the vehicle 200. The vehicle 200 can further include a lower grille panel 206 coupled adjacent to the front bumper cover 202. The lower grille panel 206 can further define the outer aerodynamic surface 204 of the vehicle 200. The lower grille panel 206 can be coupled to the front bumper cover 202. An aperture 208 can be disposed in the front bumper cover 202 and/or the lower grille panel 206 for accommodating one of the towing brackets 210. The towing bracket 210 can extend from a frame component of the vehicle through the aperture 208 so as to be accessible for coupling a tow bar (e.g., see tow bar 1 of FIG. 1) to the vehicle 200 for flat towing the vehicle 200. In the illustrated embodiment, the aperture 208 is defined by, and between, the front bumper cover 202 and the lower grille panel 206. However, the aperture 208 can be disposed only in the front bumper cover 202 or only in the lower grille panel 206. Moreover, the aperture 208 can be disposed in any vehicle panel that is part of the front fascia of the vehicle 200 at a location in front of the vehicle front bumper frame structure, depending on the particular design of the front paneling of the vehicle 200. Accordingly, as used herein the term “vehicle panel” can refer to a bumper cover, a lower grille panel, or any other vehicle panel that is part of the front fascia of the vehicle 200. A cap can be placed over or in the aperture 208 to cover the aperture 208 (e.g., for aerodynamic and/or aesthetic purposes) until it is desired to connect a tow bar to the vehicle 200.

The vehicle 500 and the vehicle body structure 512 can be similar to the vehicle 200 and the vehicle body structure 212 of FIG. 2A and FIG. 2B, except that a flat tow base plate 570 is mounted to the end portion 224 of the front side member extension 214 (i.e., instead of the towing bracket adapter 250). With respect to FIG. 5A, FIG. 5B, and FIG. 5C elements with like element numbering, as depicted in FIG. 2A, FIG. 2C, and FIG. 2D, are intended to be the same and will not necessarily be repeated for the sake of clarity.


With combined reference to FIG. 5A, FIG. 5B, and FIG. 5C, the body structure 512 includes a tow bar attachment assembly 518 including the flat tow base plate 570 mounted to the end portion 224 of the front side member extension 214 via the nut fastener 232. The flat tow base plate 570 includes a lateral beam 572 and a pair of longitudinal beams 574 located at either end of the lateral beam 572. The longitudinal beams 574 can extend longitudinally aft from the lateral beam 572 when the flat tow base plate 570 is installed on the vehicle 500.


With particular focus on FIG. 5C, each longitudinal beam 574 can be a hollow beam defining a bore 252 terminating at an inwardly extending flange 576. The longitudinal beam 574 can be received through the front of the aperture 208 and aligned with the nut fastener 232. The bore 252 can be configured to receive a fastener 580 (e.g., a threaded bolt) through the front end thereof. The fastener 580 can be a bolt configured to extend aft from the bore 252 and threadingly engage the nut fastener 232 to secure the flat tow base plate 570 to the body structure 512. The fastener 580 can compress the flange 576 between the fastener 580 and the nut fastener 232. In this regard, the longitudinal beam 574 can extend forward from the nut fastener 232 and through the aperture 208.


With particular focus on FIG. 5B, the lateral beam 572 can include a pair of attachment points 578 whereby the pair of towing brackets 210 are mounted to the flat tow base plate 570. In various embodiments, the towing brackets 210 are installed to the flat tow base plate 570 in a manner similar to the way the towing bracket 310 is installed to the towing bracket adapter 350 as illustrated in FIG. 3A through FIG. 3C. For example, the attachment points 578 can be similar to the towing bracket adapter 350, in accordance with various embodiments. In various embodiments, the attachment points 578 can be similar to the hollow bore portion 251 of the towing bracket adapter 250 and can be embedded in the lateral beam 572. However, the towing brackets 210 can be mounted to the lateral beam 572 via any suitable method.


The attachment points 578 can be laterally offset from the longitudinal beams 574. For example, the attachment points 578 can be laterally inward from the longitudinal beams 574. In this manner, the flat tow base plate 570 can act as an adapter configured to adjust a point of attachment for a tow bar 1 (e.g., from the wider attachment points of the nut fasteners 232 and longitudinal beams 574 to the narrower attachment points of the attachment points 578).


In various embodiments, the lateral beam 572 is a metal beam, such as a metal, rectangular, hollow beam. In various embodiments, the longitudinal beams 574 are metal tubes, such as metal, round, hollow tubes.



FIG. 6 is a schematic view of an exemplary flat tow base plate 670 having a lateral beam 672 and a pair of longitudinal beams 674 configured to attach to a vehicle. Towing brackets 610 are mounted to the lateral beam 672. In various embodiments, flat tow base plate 670 can be similar to the flat tow base plate 570 illustrated in FIG. 5A through FIG. 5C.


Aspects of a flat tow base plate kit, for example as illustrated in FIG. 5A through FIG. 6, includes a vehicle body/bumper structure designed to manage the increased load from flat towing, as well as meet all regulatory standards. The flat tow base plate kit can be bolted in by a user to allow attachment of an industry standard attachment, which would attach to a tow bar connected to the tow vehicle. An added benefit of this kit is it allows for adjustment of the location to attach the industry standard attachment in a vertical or horizontal direction. Similar to the thread-in adapter and the welded in adapter, the kit allows a user to retain the usage of a tow hook when the adapter is not installed, in accordance with various embodiments.
