Abstract
Description
- The present application claims priority to U.S. Provisional Patent Application No. 62/133,991, filed on Mar. 16, 2015, and U.S. Provisional Patent Application No. 62/150,848, filed on Apr. 22, 2015, the disclosures of which are hereby incorporated by reference in their entireties for all purposes.
- Exemplary embodiments of the present disclosure relate to component fastening technologies, lightweight fastening methods for components, and assemblies that may be used, for example, for an electric vehicle.
- Technology related to the fastening of dissimilar materials has become increasingly widespread throughout various industries and applications, including the automobile and aircraft industries, for example. However, one difficulty in the fastening of dissimilar materials is caused by galvanic corrosion. The phenomenon of galvanic corrosion is induced due to the difference in potentials of different metal materials when brought into contact in the presence of an electrolyte (e.g., water). In such a situation, a corrosion current is generated due to the difference in electric potentials of the dissimilar metal materials. When galvanic corrosion occurs, the strength of the joint point between the dissimilar metal materials weakens, thereby causing unexpected damage.
- To address this problem, many different techniques are used, including riveting, locking, and the like. Most of these techniques, however, are inconvenient and cause further problems, for example, the weight of the work piece may be increased by adding the extra fasteners, or looseness may occur due to insufficient joining fastness.
- Exemplary embodiments of the present disclosure may address at least some of the above-noted problems. For example, according to first aspects of the disclosure, lightweight fastening methods for components may include one or more of the following steps: providing a first component and a second component, the first component and the second component respectively provided with through holes; aligning the through holes of the first component and the second component; forming a mixture by mixing a first material with a second material; and injecting the mixture of the first material and the second material into the aligned through holes of the first component and the second component. In some examples, the mixture of the first material and the second material may expand in the through holes, e.g., due to a chemical reaction, thereby connecting the first component and the second component together.
- According to further aspects of the disclosure, an integrally fastened assembly may be formed including a first component with a first through hole, and a second component with a second through hole. During assembly, the first through hole on the first component may be aligned with the second through hole on the second component, and a connecting component may be arranged in the aligned first through hole and the second through hole. In some examples, the connecting component may be formed by injecting the mixture of a first material and a second material into the aligned through holes of the first component and the second component, and the mixture of the first material and the second material may expand in the through holes due to a chemical reaction, thereby connecting the first component and the second component together.
- In some embodiments, two kinds of glues may be mixed in the aligned through holes of the components. As the two kinds of glues are mixed, a chemical reaction may occur causing the resultant mixture to expand and solidify. After the solidifying is complete, a cap bolt may be formed, which serves to fasten, connect, or couple the two components together. As a result, the strength of the joint point between the components may be improved and the weight of the working components may not be significantly increased.
- In addition, compared with riveting techniques in the related art, when the components to be fastened are made from dissimilar metal materials, the cap bolt formed using the example embodiments of the present disclosure may eliminate or reduce abrasion, falling off, or chipping of the anti-corrosion cladding material provided on the working components. For example, the hardness of the formed cap bolt may be low, and thus, the formed cap bolt may not chip the anti-corrosion cladding material off of the components. As such, galvanic corrosion induced by the presence of an electrolyte, e.g., water, on the surfaces of the components where the anti-corrosion cladding material may have otherwise chipped or fallen off may be prevented, or inhibited, from occurring.

-
FIG. 1A -FIG. 1D are perspective structural schematic views showing a process of the lightweight fastening method for components, according to an example embodiment of the present disclosure. - As shown in
FIG. 1A , afirst component 1 and asecond component 2 are components to be fastened together. Thefirst component 1 and thesecond component 2 are respectively provided with a first throughhole 3 and a second throughhole 3′. Further, the first throughhole 3 of thefirst component 1 and the second throughhole 3′ of thesecond component 2 are aligned with each other. In some examples, thefirst component 1 andsecond component 2 may be made from dissimilar materials, such as dissimilar metal materials, or other combinations of dissimilar materials. For example, thefirst component 1 and thesecond component 2 may be made from dissimilar metal materials generally used in the automotive industry, such as steel, aluminum, alloys, etc. - Referring to
FIG. 1B , a first material 4 is mixed with asecond material 5 to form amixture 6. This may be done outside of first throughhole 3 and second throughhole 3′, inside of first throughhole 3, and/or inside of second throughhole 3′. - As shown in
FIG. 1C , themixture 6 may be injected into the aligned throughholes first component 1 and thesecond component 2. - As shown in
FIG. 1D , themixture 6 may expand in the throughholes first component 1 and thesecond component 2 are fastened or coupled together by the outer edge 7 of the expandedmixture 6. In particular, referring toFIG. 1D , themixture 6 expands outwardly on both sides of the first and second components, thereby forming a cap bolt on an upper portion of thesecond component 2 and a lower portion of thefirst component 1. - As described above, the
mixture 6 may include the first material 4 and thesecond material 5. In some examples, the first material 4 may include isocyanate, however, the first material 4 is not limited to the aromatic isocyanate group, such as diphenylmethane diisocyanate and toluene diisocyanate, or the aliphatic isocyanate group, such as hexamethylene diisocyanate and isophorone diisocyanate. Further, thesecond material 5 may include polyol, however, thesecond material 5 is not limited to the polyether group, such as polyethylene glycol and polytetrahydrofuran, or the polyester group. Additionally, the mixture is not limited to the first material 4 and thesecond material 5. In another example embodiment of the present disclosure, themixture 6 may include other materials in addition to the first material 4 and thesecond material 5. In some examples, themixture 6 may be an epoxy resin, a liquid and/or a solution that hardens based on a chemical reaction of the materials, exposure to air or other gas, exposure to energy, and/or combinations thereof. -
FIG. 2A -FIG. 2D are cross-sectional structural schematic views showing additional details of a lightweight fastening method for components, according to an example embodiment of the present disclosure. The fastening process as shown inFIG. 2A -FIG. 2D may be similar to, or the same as, the process shown inFIG. 1A -FIG. 1D . However,FIG. 2A -FIG. 2D present the process by illustrating cross-sectional views. - Referring to
FIG. 2A , the first throughhole 3 of thefirst component 1 is aligned with the second throughhole 3′ of thesecond component 2 to form aligned throughholes - In
FIG. 2B , a mixture (e.g., formed by mixing the first material 4 with the second material 5) may be injected into the throughholes - As shown in
FIG. 2C , the materials in themixture 6 may generate (alone or in combination with other materials) a chemical reaction that expands the mixture outwardly along the arrows as shown inFIG. 2C . - Further, as shown in
FIG. 2D , after expanding, themixture 6 may directly form an outward extending edge 7 (e.g., a cap bolt) with an area greater than an area of the throughholes first component 1 and thesecond component 2. After solidifying to a solid state, the cap bolt is formed after solidifying to fasten the two working components, and the fastening strength at the joint point of thefirst component 1 and thesecond component 2 may be improved. Further, the cap bolt may be relatively lightweight, e.g., so that it will not add extra weight to the working components. - It should be noted that, although shown as substantially similar in shape and size, the through
holes FIG. 2D , a monolithic (i.e., formed as a single piece) connecting component, such as connecting component 7, may be disposed at least partially in the first through hole and the second through hole, and include a first expanded portion that is wider than the first through hole and a second expanded portion that is wider than the second through hole. In some examples, such as when one or both of the through holes are tapered, the expanded portion outside of the through holes may be omitted and/or removed. - In addition, the hardness of the cap bolt formed by the
mixture 6 may be relatively low compared to the materials infirst component 1,second component 2, and/or any cladding or other coating affixed to or formed on the components. As such, the formed cap bolt may prevent, or reduce, for example, abrasion, falling off, or chipping of the anti-corrosion cladding material provided on thefirst component 1 andsecond component 2. As a result, the galvanic corrosion induced by the presence of an electrolyte (e.g., water) on the surfaces of the components where the anti-corrosion cladding material may have otherwise chipped or fallen off may be prevented, or inhibited, from occurring. - Referring now to
FIG. 3 , an example block diagram for a computer system or otheronboard computer device 300 which may be operatively connected to the motor rotor assembly, the gear box, and/or any other components described above and provided by the electric vehicle is shown. It is contemplated that the computer system or otheronboard computer device 300 may control one or more aspects of the electric vehicle and/or features described above. In some examples, the computer system or otheronboard computer device 300 may include a tablet computer, personal data assistant, smartphone, gaming console, and/or a dedicated computer system for controlling the electric vehicle. Any particular one of the previously-described computing devices may be wholly or at least partially configured to exhibit features similar to thecomputer system 300. - The
computer device 300 is shown comprising hardware elements that may be electrically coupled via a bus 302 (or may otherwise be in communication, as appropriate). The hardware elements may include a processing unit with one ormore processors 304, including without limitation one or more general-purpose processors and/or one or more special-purpose processors (such as digital signal processing chips, graphics acceleration processors, and/or the like); one ormore input devices 306, which may include without limitation a steering wheel, a climate control button or other user input receiving buttons, and/or the like; and one ormore output devices 308, which may include without limitation a presentation device (e.g., a computer screen), a GPS, and/or the like. - The
computer system 300 may further include (and/or be in communication with) one or morenon-transitory storage devices 310, which may comprise, without limitation, local and/or network accessible storage, and/or may include, without limitation, a disk drive, a drive array, an optical storage device, a solid-state storage device, such as a random access memory, and/or a read-only memory, which may be programmable, flash-updateable, and/or the like. Such storage devices may be configured to implement any appropriate data stores, including without limitation, various file systems, database structures, and/or the like. - The
computer device 300 might also include acommunications subsystem 312, which may include without limitation a modem, a network card (wireless and/or wired), an infrared communication device, a wireless communication device and/or a chipset such as a Bluetooth™ device, 802.11 device, WiFi device, WiMax device, cellular communication facilities such as GSM (Global System for Mobile Communications), W-CDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), etc., and/or the like. Thecommunications subsystem 312 may permit data to be exchanged with a network (such as the network described below, to name one example), other computer systems, and/or any other devices described herein. In many embodiments, thecomputer system 300 will further comprise a workingmemory 314, which may include a random access memory and/or a read-only memory device, as described above. - The
computer device 300 also may comprise software elements, shown as being currently located within the workingmemory 314, including anoperating system 316, device drivers, executable libraries, and/or other code, such as one ormore application programs 318, which may comprise computer programs provided by various embodiments, and/or may be designed to implement methods, and/or configure systems, provided by other embodiments, as described herein. By way of example, one or more procedures described with respect to the method(s) discussed above, and/or system components might be implemented as code and/or instructions executable by a computer (and/or a processor within a computer); in an aspect, then, such code and/or instructions may be used to configure and/or adapt a general purpose computer (or other device) to perform one or more operations in accordance with the described methods. - A set of these instructions and/or code might be stored on a non-transitory computer-readable storage medium, such as the storage device(s) 310 described above. In some cases, the storage medium might be incorporated within a computer system, such as
computer system 300. In other embodiments, the storage medium might be separate from a computer system (e.g., a removable medium, such as flash memory), and/or provided in an installation package, such that the storage medium may be used to program, configure, and/or adapt a general purpose computer with the instructions/code stored thereon. These instructions might take the form of executable code, which is executable by thecomputer device 300 and/or might take the form of source and/or installable code, which, upon compilation and/or installation on the computer system 300 (e.g., using any of a variety of generally available compilers, installation programs, compression/decompression utilities, etc.), then takes the form of executable code. - It will be apparent that substantial variations may be made in accordance with specific requirements. For example, customized hardware might also be used, and/or particular elements might be implemented in hardware, software (including portable software, such as applets, etc.), or both. Further, connection to other computing devices such as network input/output devices may be employed.
- As mentioned above, in one aspect, some embodiments may employ a computer system (such as the computer device 300) to perform methods in accordance with various embodiments of the disclosure. According to a set of embodiments, some or all of the procedures of such methods are performed by the
computer system 300 in response toprocessor 304 executing one or more sequences of one or more instructions (which might be incorporated into theoperating system 316 and/or other code, such as an application program 318) contained in the workingmemory 314. Such instructions may be read into the workingmemory 314 from another computer-readable medium, such as one or more of the storage device(s) 310. Merely by way of example, execution of the sequences of instructions contained in the workingmemory 314 may cause the processor(s) 304 to perform one or more procedures of the methods described herein. - The terms “machine-readable medium” and “computer-readable medium,” as used herein, may refer to any non-transitory medium that participates in providing data that causes a machine to operate in a specific fashion. In an embodiment implemented using the
computer device 300, various computer-readable media might be involved in providing instructions/code to processor(s) 304 for execution and/or might be used to store and/or carry such instructions/code. In many implementations, a computer-readable medium is a physical and/or tangible storage medium. Such a medium may take the form of a non-volatile media or volatile media. Non-volatile media may include, for example, optical and/or magnetic disks, such as the storage device(s) 310. Volatile media may include, without limitation, dynamic memory, such as the workingmemory 314. - Example forms of physical and/or tangible computer-readable media may include a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a compact disc, any other optical medium, ROM, RAM, and etc., any other memory chip or cartridge, or any other medium from which a computer may read instructions and/or code. Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to the processor(s) 304 for execution. By way of example, the instructions may initially be carried on a magnetic disk and/or optical disc of a remote computer. A remote computer might load the instructions into its dynamic memory and send the instructions as signals over a transmission medium to be received and/or executed by the
computer system 300. - The communications subsystem 312 (and/or components thereof) generally will receive signals, and the
bus 302 then might carry the signals (and/or the data, instructions, etc. carried by the signals) to the workingmemory 314, from which the processor(s) 304 retrieves and executes the instructions. The instructions received by the workingmemory 314 may optionally be stored on anon-transitory storage device 310 either before or after execution by the processor(s) 304. - It should further be understood that the components of
computer device 300 can be distributed across a network. For example, some processing may be performed in one location using a first processor while other processing may be performed by another processor remote from the first processor. Other components ofcomputer system 300 may be similarly distributed. As such,computer device 300 may be interpreted as a distributed computing system that performs processing in multiple locations. In some instances,computer system 300 may be interpreted as a single computing device, such as a distinct laptop, desktop computer, or the like, depending on the context. - Although the present invention has been described with reference to the specific embodiments shown in the drawings, it should be understood that the motor rotor assembly and the electric vehicle motor provided by the present invention can have a variety of variations without departing from the spirit, scope and background of the present invention. Those of ordinary skill in the art should be still aware that, parameters in the embodiments disclosed by the present invention are changed in different manners, for example, sizes, shapes, elements or types of materials, and these changes shall fall within the spirit and scope of the present invention and the claims.
- The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various method steps or procedures, or system components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and/or various stages may be added, omitted, and/or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.
