Swappable and stackable batteries are being deployed in a wide variety of applications. Some swappable and stackable batteries are proprietary to OEM (Original Equipment Manufacturers such as FORD). Batteries can charge other connected batteries and the stack of batteries may be added to or subtracted from. With the high cos Some swappable and stackable batteries t of an individual battery and related systems it can be assumed that owners would want to secure these batteries. It is envisioned that robots and other autonomous devices will be configured to swap their own batteries autonomously or manually.
In many instances, current configurations require a high degree of precision to correctly align the robot and battery receptacle. For example, if an autonomous robotic platform is intended to swap its own battery the precision required in the x and y planes is very tight. The connector of a battery is not able to reposition itself within the battery to account for a misalignment. Also, docking a battery to a battery station requires precise timing for the opening of the locks so that docking may occur.
A detailed description is set forth regarding the accompanying drawings. The use of the same reference numerals may indicate similar or identical items. Various embodiments may utilize elements and/or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. Elements and/or components in the figures are not necessarily drawn to scale. Throughout this disclosure, depending on the context, singular and plural terminology may be used interchangeably.
This disclosure pertains to self-locking alignment systems and methods for stackable batteries. An example system involves using a combination of mechanical and electrical actuation for locking. A locking mechanism that can be latched mechanically, as well as electronically, can provide the necessary smart security features while still being able to be plugged in, secured, and charged while the battery is too low on power to actuate the electronic locks. There may be one lock per alignment mechanism, or one lock per pair or group of alignment mechanisms. By incorporating physical alignment features, it is possible to guide a robot or autonomous device to subtly move the receptacle/second battery to ensure a successful battery pickup or drop-off. The systems and methods herein provide for 180-degree rotational symmetry. Batteries can be locked and unlocked electronically and do not require special timing of lock actuation to place a battery onto the stack. Some embodiments may include two locking members, for instance, one per alignment member, but some embodiments can utilize a single locking member or mechanism. In some embodiments, the locking member locks automatically, without user input, when one battery assembly is stacked on another battery assembly.
Turning now to the drawings,

In one example, the first alignment mechanism 112 can include a polygonal base 116 with an arcuate dome 118. The arcuate dome 118 can have tapered sides 120 and 122. Both the arcuate dome and tapered sides provide for alignment of the battery with its intended receptor, such as another battery of receptacle of a device, such as a robot. It will be understood that the shape described is not intended to be limiting and the shape alignment mechanisms can vary according to design parameters.
Each of the alignment mechanisms can include a locking member, such as locking member 124. The locking member 124 can include a plunger 126 that has a tapered end 128 of the latch. The latch may be spring loaded to allow the latch to recess recoil slightly when on assembly is stack on another assembly. When the latch returns to its biased position, which may be the result of a spring biasing the latch out, the latch edge catches the assembly of the strike plate of the other assembly.
The plunger 126 can be driven manually or by a mechanism such as a motor or solenoid. The mechanism used to translate the plunger between locked (extended) and unlocked (retracted) positions can be housed within the polygonal base 116. As noted throughout, the second alignment mechanism 114 can also include a locking member that is identical to the locking member 124 of the first alignment mechanism 112. While one locking member 124 is shown in

The first alignment receiver 130 and the second alignment receiver 132 are substantially identical in construction related to one another. Thus, descriptions of the first alignment receiver 130 are equally applicable to the second alignment receiver 132. The first alignment receiver 130, in general is a negative or female cavity that is shaped to correspond with the first alignment mechanism 112. That is, the first alignment mechanism 112 is configured to nest or mate within a cavity as best illustrated in
For example, as illustrated in
Referring briefly to
The placement, spacing and configuration of the first alignment receiver 130 and the second alignment receiver 132 substantially corresponds to the placement, spacing and configuration of the first alignment mechanism 112 and the second alignment mechanism 114. This ensures that when the second stackable battery assembly 104 is placed on to the first stackable battery assembly that the first alignment mechanism 112 and the second alignment mechanism 114 nest inside the first alignment receiver 130 and the second alignment receiver 132, respectively, of the first battery assembly 102.
In some examples, the battery 110 can be disposed between the first alignment receiver 130 and the second alignment receiver 132. Any number of batteries can be located inside the container 108, and may be of any suitable shape or configuration.
Also, the container 108 can include a pair of docking interfaces 154 and 156 located on opposing surfaces of the container 108. A robot can insert a lever through the docking interfaces 154 and 156 in order to remove or replace the first stackable battery assembly 102, such as into a stackable battery assembly kiosk (see
Referring to
In one example, the robot 146 can transmit a signal to the controller 140 that will cause the locking member 124 to lock or unlock (depending on context) the battery assembly 102. For example, when the robot 146 approaches a stack of stackable battery assemblies, the robot 146 can transmit a signal to the controller 140 requesting one of the stackable battery assembly to unlock itself from an adjacently stacked battery. For example, the plunger may be retracted into an unlocked position, which allows first stackable battery assembly 102 to be removed from the second stackable battery assembly 104.
The first stackable battery assembly 102 can also comprise an electrical interface 152 that can be positioned anywhere on any surface of the first stackable battery assembly 102. The electrical interface 152 can mate with a corresponding electrical interface of another stackable battery assembly (stackable battery assemblies are in a stacked configuration). The electrical interface 150 can interface with a corresponding electrical interface on the robot 146, allowing the robot 146 to receive electrical power from the battery 110 of the first stackable battery assembly 102.
Bay 402 only includes a single battery assembly, which allows for the receipt of stackable battery assemblies that require charging. Also, the bay 402 can function as a staging area and receive batteries temporarily. For example, if a robot 502 desired to obtain a stackable battery assembly 408 located within the bay 404, the robot 502 could remove stackable battery assemblies above the stackable battery assembly 408 (if any). These removed stackable battery assemblies can be temporarily placed, by the robot 502 in the bay 402 and returned to the bay 404 (if desired).

Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims may not necessarily be limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims.
While various embodiments of the present disclosure have been described above, it should be understood that they have been presented by way of example only, and not limitation. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the present disclosure. Thus, the breadth and scope of the present disclosure should not be limited by any of the above-described exemplary embodiments but should be defined only in accordance with the following claims and their equivalents.

Further, it should be noted that any or all of the aforementioned alternate implementations may be used in any combination desired to form additional hybrid implementations of the present disclosure. For example, any of the functionality described with respect to a particular device or component may be performed by another device or component. Conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments could include, while other embodiments may not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments.
Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Furthermore, depending on the context of discussion herein, a singular term may include its plural forms and a plural term may include its singular form. Similarly, a hyphenated term (e.g., “on-demand”) may be occasionally interchangeably used with its non-hyphenated version (e.g., “on demand”), a capitalized entry (e.g., “Software”) may be interchangeably used with its non-capitalized version (e.g., “software”), a plural term may be indicated with or without an apostrophe (e.g., PE's or PEs), and an italicized term (e.g., “N+1”) may be interchangeably used with its non-italicized version (e.g., “N+1”). Such occasional interchangeable uses shall not be considered inconsistent with each other.
Also, some embodiments may be described in terms of “means for” performing a task or set of tasks. It will be understood that a “means for” may be expressed herein in terms of a structure, such as a processor, a memory, an I/O device such as a camera, or combinations thereof. Alternatively, the “means for” may include an algorithm that is descriptive of a function or method step, while in yet other embodiments the “means for” is expressed in terms of a mathematical formula, prose, or as a flow chart or signal diagram.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is noted at the outset that the terms “coupled,” “connected”, “connecting,” “mechanically connected,” etc., are used interchangeably herein to generally refer to the condition of being mechanically/physically connected. The terms “couple” and “coupling” are also used in a non-mechanical/physical context that refers to absorption of microwave energy by a material. It is further noted that various figures (including component diagrams) shown and discussed herein are for illustrative purpose only, and are not drawn to scale. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
If any disclosures are incorporated herein by reference and such incorporated disclosures conflict in part and/or in whole with the present disclosure, then to the extent of conflict, and/or broader disclosure, and/or broader definition of terms, the present disclosure controls. If such incorporated disclosures conflict in part and/or in whole with one another, then to the extent of conflict, the later-dated disclosure controls.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized and/or overly formal sense unless expressly so defined herein.
The terminology used herein can imply direct or indirect, full or partial, temporary or permanent, immediate or delayed, synchronous or asynchronous, action or inaction. For example, when an element is referred to as being “on,” “connected” or “coupled” to another element, then the element can be directly on, connected or coupled to the other element and/or intervening elements may be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.
Although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.
Example embodiments of the present disclosure are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the present disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the example embodiments of the present disclosure should not be construed as necessarily limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing.
Any and/or all elements, as disclosed herein, can be formed from a same, structurally continuous piece, such as being unitary, and/or be separately manufactured and/or connected, such as being an assembly and/or modules. Any and/or all elements, as disclosed herein, can be manufactured via any manufacturing processes, whether additive manufacturing, subtractive manufacturing and/or other any other types of manufacturing. For example, some manufacturing processes include three-dimensional (3D) printing, laser cutting, computer numerical control (CNC) routing, milling, pressing, stamping, vacuum forming, hydroforming, injection molding, lithography and/or others.
Any and/or all elements, as disclosed herein, can include, whether partially and/or fully, a solid, including a metal, a mineral, a ceramic, an amorphous solid, such as glass, a glass ceramic, an organic solid, such as wood and/or a polymer, such as rubber, a composite material, a semiconductor, a nano-material, a biomaterial and/or any combinations thereof. Any and/or all elements, as disclosed herein, can include, whether partially and/or fully, a coating, including an informational coating, such as ink, an adhesive coating, a melt-adhesive coating, such as vacuum seal and/or heat seal, a release coating, such as tape liner, a low surface energy coating, an optical coating, such as for tint, color, hue, saturation, tone, shade, transparency, translucency, non-transparency, luminescence, anti-reflection and/or holographic, a photo-sensitive coating, an electronic and/or thermal property coating, such as for passivity, insulation, resistance or conduction, a magnetic coating, a water-resistant and/or waterproof coating, a scent coating and/or any combinations thereof.
Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” may be used herein to describe one element's relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings is turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can, therefore, encompass both an orientation of above and below.
While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. The descriptions are not intended to limit the scope of the invention to the particular forms set forth herein. To the contrary, the present descriptions are intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims and otherwise appreciated by one of ordinary skill in the art. Thus, the breadth and scope of a preferred embodiment should not be limited by any of the above-described exemplary embodiments.
