The work of the currently named inventors, to the extent described in this section, and in aspects that may not qualify as prior art at the time of filing, is neither expressly nor implicitly acknowledged as prior art to this disclosure. Technical Field

[0002] This disclosure generally relates to a gasket, and more specifically, to an additively manufactured gasket. Background Technology

[0003] Press-in-place (PIP) gaskets or seals are commonly used in engines (e.g., camshaft covers, oil pans, front covers, water pumps, etc.), transmissions (side covers, transmission discs, electrical module covers, etc.), electrical systems, and energy systems. In many cases, PIP gaskets are designed to fit into complex groove patterns on mating surfaces of interfaces. Furthermore, these gaskets are designed to withstand various environments, fluids, pressures, and temperatures. The machining required to manufacture these conventional PIP gaskets is time-consuming. Therefore, there is a need to manufacture gaskets without relying on traditional injection molding techniques. Summary of the Invention

[0031] In all the accompanying drawings, the corresponding reference numerals denote the corresponding parts. Detailed Implementation

[0032] The example configuration will now be described more fully with reference to the accompanying drawings. The example configuration is provided so that this disclosure will be thorough and will fully communicate the scope of this disclosure to those skilled in the art. Specific details, such as examples of specific components, apparatus, and methods, are set forth to provide a thorough understanding of the configuration of this disclosure. It will be apparent to those skilled in the art that specific details are not required, the example configuration may be embodied in many different forms, and the specific details and example configuration should not be construed as limiting the scope of this disclosure.

[0033] The terminology used herein is for the purpose of describing a particular exemplary configuration only and is not intended to be limiting. As used herein, the singular articles “a” and “the” may also be intended to include plural forms unless the context clearly indicates otherwise. The terms “comprising,” “including,” and “having” are inclusive and therefore specify the presence of features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0034] When an element or layer is referred to as “on another element or layer,” “joined to,” “connected to,” “attached to,” or “linked to” another element or layer, it may be directly on, joined to, connected to, attached to, or linked to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly linked to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” vs. “directly between,” “adjacent” vs. “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0035] The terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts. These elements, components, regions, layers, and / or parts should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or part from another. Unless the context clearly indicates otherwise, terms such as “first,” “second,” and other numerical terms do not imply order or sequence. Therefore, without departing from the teachings of the example configuration, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part.

[0036] In this application, including the following definitions, the term "module" may be replaced by the term "circuit".

The term "shared memory" covers a single memory that stores some or all of the code from multiple modules. The term "group memory" includes memory that, in combination with additional memory, stores some or all of the code from one or more modules. The term "memory" can be a subset of the term "computer-readable medium." The term "computer-readable medium" does not include transient electrical and electromagnetic signals propagating through the medium and can therefore be considered tangible and non-transitory memory. Non-limiting examples of non-transitory memory include tangible computer-readable media, which include non-volatile memory, magnetic memory, and optical memory.

[0038] The apparatus and methods described in this application can be implemented, partially or entirely, by one or more computer programs executed by one or more processors. The computer program includes processor-executable instructions stored on at least one non-transitory tangible computer-readable medium. The computer program may also include and / or depend on stored data.

[0039] A software application (i.e., a software resource) can refer to computer software that enables a computing device to perform tasks. In some examples, a software application may be referred to as an "application," "app," or "program." Example applications include, but are not limited to, system diagnostic applications, system management applications, system maintenance applications, word processing applications, spreadsheet applications, messaging applications, media streaming applications, social networking applications, and game applications.

[0040] Non-transitory memory can be a physical device used to temporarily or permanently store programs (e.g., instruction sequences) or data (e.g., program state information) for use by a computing device. Non-transitory memory can be volatile and / or non-volatile addressable semiconductor memory. Examples of non-volatile memory include, but are not limited to, flash memory and read-only memory (ROM) / programmable read-only memory (PROM) / erasable programmable read-only memory (EPROM) / electrically erasable programmable read-only memory (EEPROM) (e.g., commonly used in firmware, such as boot programs). Examples of volatile memory include, but are not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), phase-change memory (PCM), and magnetic disks or magnetic tapes.

[0041] These computer programs (also referred to as programs, software, software applications, or code) include machine instructions for a programmable processor and can be implemented using high-level procedural and / or object-oriented programming languages ​​and / or assembly / machine languages. As used herein, the terms “machine-readable medium” and “computer-readable medium” refer to any computer program product, non-transitory computer-readable medium, apparatus, and / or device (e.g., disk, optical disk, memory, programmable logic device (PLD)) used to provide machine instructions and / or data to a programmable processor, including machine-readable media that receive machine instructions as machine-readable signals. The term “machine-readable signal” refers to any signal used to provide machine instructions and / or data to a programmable processor.

[0042] Various implementations of the systems and techniques described herein can be implemented in digital electronic and / or optical circuits, integrated circuits, specially designed ASICs (Application-Specific Integrated Circuits), computer hardware, firmware, software, and / or combinations thereof.

[0043] The processes and logical flows described in this specification can be executed by one or more programmable processors (also known as data processing hardware) that execute one or more computer programs to perform functions by manipulating input data and generating output. The processes and logical flows can also be executed by special-purpose logic circuitry (e.g., FPGAs (Field-Programmable Gate Arrays) or ASICs (Application-Specific Integrated Circuits). As an example, processors suitable for executing computer programs include both general-purpose and special-purpose microprocessors, as well as any one or more processors of any type of digital computer. Typically, the processor receives instructions and data from read-only memory or random access memory, or both. The basic elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Typically, a computer will also include one or more mass storage devices (e.g., magnetic disks, magneto-optical disks, or optical disks) for storing data, or operatively coupled to receive data from or transfer data to, or both. However, a computer does not need to have such devices. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media, and memory devices, including, for example, semiconductor memory devices such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks or removable disks; magneto-optical disks; and CD-ROMs and DVD-ROMs. Processors and memory may be supplemented by or incorporated into dedicated logic circuitry.

[0044] To provide interaction with a user, one or more aspects of this disclosure can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube), LCD (liquid crystal display) monitor, or touchscreen) for displaying information to the user and optionally a keyboard and pointing device (e.g., a mouse or trackball) through which the user provides input to the computer. Other types of devices can also be used to provide interaction with the user; for example, feedback provided to the user can be any form of sensory feedback, such as visual, auditory, or tactile feedback; and input from the user can be received in any form, including sound, speech, or tactile input. Additionally, the computer can interact with the user by sending documents to and receiving documents from the device used by the user; for example, by sending a webpage to a web browser on the user's client device in response to a request received from a web browser.

[0045] refer to Figure 1This provides an additively manufactured gasket or seal 10. Gasket 10 may also be referred to as a press-in (PIP) gasket. Traditionally, PIP gaskets are manufactured using injection molding, have a solid core (i.e., no hollow portion), and can be used in a wide range of environments, fluids, pressures, and temperatures. Manufacturing gaskets using other technologies, such as additive manufacturing, presents many challenges not encountered with conventional injection-molded gaskets or solid core gaskets.

[0046] refer to Figure 2 A partial perspective view is provided showing another configuration of an additively manufactured washer 100 arranged in a portion of a groove 50. In this example, the groove 50 is four millimeters wide by six millimeters deep. Note that the principles of this disclosure are equally applicable to grooves of different shapes, sizes, and / or dimensions.

[0047] refer to Figure 2 and Figures 3A-3C The washer 100 may include a body 102, which includes an outer wall 104, an inner wall 106 opposite to the outer wall 104, and a hollow cavity 108 defined by the inner wall 106. The hollow cavity 108 includes a washer cavity space 110. The washer cavity space 110 may be expressed as the product of the cross-sectional area of ​​the hollow cavity 108 and the perimeter of the washer 100. The body 102 may also be defined by a height 112, a width 113, a gap 114, and a thickness 116 between the inner wall 106 and the outer wall 104. In this example, the height 112 may be greater than 7.8 mm and less than 8.5 mm, the gap 114 may be greater than 1.0 mm and less than 1.5 mm, and the thickness 116 may be greater than 0.5 mm and less than 1.0 mm. The body 102 may have a substantially elliptical shape, such as... Figure 3A As shown. Alternatively, the body 102 may be made of, for example, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), or another material commonly used in additive manufacturing (e.g., polymer powder bed fusion) vehicle parts.

[0048] The body 102 may include one or more intermittent retaining features 118. The one or more intermittent retaining features 118 may be at least partially embedded in the body 102 and / or extend from the outer wall 104. The one or more intermittent retaining features 118 may include a first feature 120 and a second feature 122. The first feature 120 may be a stabilizing feature that stabilizes the washer 100 within the recess 50. The first feature 120 may be further defined by a first width 124 and a first height 126. The first width 124 is less than the width of the recess 50, and the first height 126 is greater than half the height 112 of the washer 100. The second feature 122 is spaced apart from the first feature 120 and may be referred to as a retaining feature that holds the washer 100 within the recess 50. The second feature 122 may be further defined by a second width 128 and a second height 130. The second width 128 is greater than the width of the recess 50, and the second height 130 is greater than half the height 112 of the washer 100.

[0049] refer to Figure 3A , Figure 3B and Figure 3C The gasket 100 may also include an uncured powder core 132 disposed in the hollow cavity 108. In this configuration, the uncured powder core 132 is made of the same material as the body 102. Therefore, if the body 102 is made of thermoplastic polyurethane, the uncured powder core 132 is also made of thermoplastic polyurethane in its raw and unprocessed state. The uncured powder core 132 may occupy 75% to 90% of the total gasket volume of the gasket 100. The total gasket volume may include the volume of the body 102 and the cavity space 110 occupied by the uncured powder core 132.

[0050] At the start of the additive manufacturing of gasket 100, a thin layer of material (e.g., thermoplastic polyurethane powder) is melted using a laser or ultraviolet (UV) light, forming a single anisotropic layer. A second thin layer of material (e.g., thermoplastic polyurethane powder) is placed on the first layer and treated with a laser or UV light, such that the first and second layers together form a single anisotropic structure. This process can be repeated until the body 102 is formed into a single anisotropic structure. During the manufacturing of gasket 100, the selected material is not treated with a laser or UV light and therefore remains uncured (i.e., does not undergo a material change process). In other words, as the body 102 is additively manufactured around the uncured powder core 132, the uncured powder core 132 is gradually trapped within the body 102. As will be discussed in more detail below, the uncured powder core 132 can act as a buffer, providing stability when gasket 100 is under compressive load, thereby ensuring a compressive ratio greater than 20% for a secure seal. The gasket 100 is manufactured by additive manufacturing to ensure that the body 102 is airtight and stable over a wide range of temperatures without failing.

[0051] Figure 4 , Figure 5A , Figure 5B and Figure 5C Another exemplary configuration of the additively manufactured washer 200 is shown. This configuration is similar in many respects to... Figure 2 , Figure 3A , Figure 3B and Figure 3C The configurations are therefore combined here, and descriptions of the various configurations are generally not repeated on topics common to all configurations.

[0052] refer to Figure 4 An additively manufactured washer 200 is disposed and arranged in a portion of a recess 50. The washer 200 may include a body 202, which includes an outer wall 204, an inner wall 206 opposite to the outer wall 204, and a hollow cavity 208 defined by the inner wall 206, such as... Figure 5A As shown. The hollow cavity 208 includes a gasket cavity space 210. In this configuration, the body 202 may have a substantially rhomboid shape. The body 202 may also be defined by a height 212, a width 213, a gap 214, and a thickness 216 between the inner wall 206 and the outer wall 204.

[0053] refer to Figure 5B and Figure 5C The body 202 may include one or more intermittent retaining features 218. The one or more intermittent retaining features 218 may be at least partially embedded in the body 202 and / or extend from the outer wall 204. The one or more intermittent retaining features 218 may include a first feature 220 and a second feature 222. The first feature 220 may be a stabilizing feature that stabilizes the washer 200 within the recess 50. The first feature 220 may be further defined by a first width 224 and a first height 226. The first width 224 is less than the width of the recess 50, and the first height 226 is greater than half the height 212 of the washer 100. The second feature 222 is spaced apart from the first feature 220 and may be referred to as a retaining feature that holds the washer 100 within the recess 50. The second feature 222 may be further defined by a second width 228 and a second height 230. The second width 228 is greater than the width of the recess 50, and the second height is greater than half the height 212 of the washer 100.

[0054] refer to Figure 5A , Figure 5B and Figure 5C The gasket 200 may also include an uncured powder core 232 disposed in the hollow cavity 208. In this configuration, the uncured powder core 232 is made of the same material as the body 202.

[0055] Figure 6 and Figure 7Another illustrative configuration of the additively manufactured gasket 300 is shown. This configuration is similar in many respects to... Figure 2 and Figures 3A-3C as well as Figure 4 and Figures 5A-5C The configurations are as follows. Therefore, the descriptions of each configuration are combined here, and descriptions of topics common to all configurations are generally not repeated.

[0056] refer to Figure 6 An additively manufactured washer 300 is disposed and arranged in a portion of a recess 50. The washer 300 may include a body 302, which includes an outer wall 304, an inner wall 306 opposite to the outer wall 304, and a hollow cavity 308 defined by the inner wall 306, as shown below. Figure 7 As shown. The hollow cavity 308 includes a gasket cavity space 310. In this configuration, the body 302 may have a generally marquise shape, such as... Figure 7 As shown. The main body 302 can also be defined by a height 312, a width 313, a gap 314, and a thickness 316 between the inner wall 306 and the outer wall 306.

[0057] refer to Figure 7 The body 302 may include one or more intermittent retaining features 318. The one or more intermittent retaining features 318 may be at least partially embedded in the body 302 and / or extend from the outer wall 304. The one or more intermittent retaining features 318 may include ribbed features 336. Ribbed features 336 may be referred to as retaining features that hold the washer 300 within the recess 50. Each ribbed feature 336 has less contact with the recess 50 compared to the first features 120, 220 and the second features 122, 222 of the washers 100, 200. Ribbed features 336 may be further defined by a rib height 338, which is less than half the height 312 of the washer 300.

[0058] refer to Figure 7 The gasket 300 may also include an uncured powder core 332 disposed in the hollow cavity 308. In this configuration, the uncured powder core 332 is made of the same material as the body 302.

[0059] refer to Figure 8A and Figure 8B When in the mass block 402 (i.e., in Figure 8B Under a compressive load (denoted as m), the washers 100, 200, and 300 of this disclosure can be compared with the Kevin-Voigt material model 400. The mass block 402 can be a non-grooved mating flange that presses downwards onto the washer 100 during joint closure. Referring to Figure 8, the body 102 can serve as a spring 404 and has a spring constant 406 (i.e., ...). Figure 8BThe spring constant k in the figure. Additionally, the uncured powder core 132 can be used as a buffer 408 and includes a damping coefficient 410 (i.e., ...). Figure 8B The damping coefficient c). The uncured powder 132 provides a certain degree of damping when the joint is closed, and may be desirable for maintaining the stability of the cross section (e.g., making it less prone to bending during joint closure).

[0060] refer to Figure 9 Method 500 for manufacturing washers 100, 200, and 300 is provided based on the principles of this disclosure. Method 500 begins at 510. Specifically, method 500 begins when an additive manufacturing machine or chamber (e.g., a 3D printer, powder bed fusion machine, etc.) is programmed to build, manufacture, and / or produce at least one of washers 100, 200, and 300. The remaining steps of method 500 will be discussed with reference to the manufacture of washer 100, but are equally applicable to the manufacture of washers 200 and 300.

[0061] At 520, the body 102 is additively manufactured to include an outer wall 104, an inner wall 106 opposite to the outer wall 104, a hollow cavity 108 defined by the inner wall 106, and one or more intermittent retaining features 118 that are at least partially embedded in the body 102 and / or extend from the outer wall 104. During 502, as described above, when the body 102 is additively manufactured, the uncured powder core 132 is captured by the body 102.

[0062] At 530, the outer wall 104 is treated with a surface treatment process such as vapor polishing. After 520, the outer wall 104 may have a certain degree of inhomogeneity and / or surface porosity, which can be addressed by another surface treatment process, vapor polishing. Treating the surface of the outer wall 104 may be desirable to improve the performance of the gasket 100 and prevent leakage that might otherwise be caused by surface porosity.

[0063] At point 540, method 500 ends.

[0064] Many embodiments have been described. However, it should be understood that various modifications can be made without departing from the spirit and scope of this disclosure. Therefore, other embodiments are within the scope of the appended claims.

[0065] The foregoing description is provided for illustrative and descriptive purposes. It is not intended to be exhaustive or limiting of this disclosure. Elements or features of a particular configuration are generally not limited to that particular configuration, but are interchangeable where applicable and can be used in selected configurations, even if not specifically shown or described. They can also be varied in many ways. Such variations should not be considered as departing from this disclosure, and all such modifications are intended to be included within the scope of this disclosure.
