Patent Application
20230133031
The present disclosure relates to modular information handling systems. More specifically, embodiments of the disclosure provide systems and methods for a gear train side latching mechanism for a modular information handling resource.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Oftentimes, information handling systems and other information handling resources (e.g., storage devices, input/output devices, and other peripheral devices) are each manufactured in a modular form factor and may be configured to be disposed in a chassis configured to receive such modular components. Such a chassis and its component modular information handling systems and information handling resources typically include various rails, carriers, and other mechanical components allowing for a person to add and remove the modular information handling systems and information handling resources from the chassis. In traditional modular systems, information handling resources (including hard disk drives) and their corresponding chassis bays are typically accessed from a side of the chassis in which the information handling resources may be added or removed.
It is desirable in most instances to provide users (e.g., information technology technicians or administrators) a convenient way to insert and remove information handling resources from a chassis. For instance, when a user desires to remove an information handling resource from a chassis, a mating force between electrical connectors on the information handling resource and within the chassis, along with other mechanical forces (e.g., friction between the chassis and the information handling resource) must be overcome for removal. However, server density continues to increase with every new generation of products, and the need to expand server width to allow more payload and increased airflow is becoming more critical. This server density has led to height and size restrictions of many information handling resources and associated chassis slots, thus rendering it difficult to provide sufficient mechanical advantage for easy removal of information handling resources.
In accordance with the teachings of the present disclosure, the disadvantages and problems associated with traditional approaches to insertion and removal of modular information handling resources in a chassis have been substantially reduced or eliminated.
In accordance with embodiments of the present disclosure, an information handling resource may include a housing configured to enclose components of the information handling resource and a latch comprising a body and a purchase. The body may be mechanically coupled to the housing such that the latch is rotatable relative to the housing about an axis parallel to an exterior face of the housing and further rotatable in a plane perpendicular to the exterior face such that the body is rotatable from a closed position relative to the housing to an open position relative to the housing and vice versa. The purchase may be mechanically coupled to the body such that the purchase is rotatable relative to the body about an axis parallel to the plane in which the body rotates relative to the housing such that the purchase is rotatable from a first position relative to the body to a second position relative to the body and vice versa, such that when in the second position, the purchase provides a mechanical advantage for removal of the information handling resource from an information handling system.
In accordance with these and other embodiments of the present disclosure, a latch may include a body and a purchase. The body may be configured to mechanically couple to a housing of an information handling system such that the latch is rotatable relative to the housing about an axis parallel to an exterior face of the housing and further rotatable in a plane perpendicular to the exterior face such that the body is rotatable from a closed position relative to the housing to an open position relative to the housing and vice versa. The purchase may be mechanically coupled to the body such that the purchase is rotatable relative to the body about an axis parallel to the plane in which the body rotates relative to the housing such that the purchase is rotatable from a first position relative to the body to a second position relative to the body and vice versa, such that when in the second position, the purchase provides a mechanical advantage for removal of the information handling resource from an information handling system.
In accordance with these and other embodiments of the present disclosure, a method may include mechanically coupling a body of a latch to a housing of an information handling resource such that the latch is rotatable relative to the housing about an axis parallel to an exterior face of the housing and further rotatable in a plane perpendicular to the exterior face such that the body is rotatable from a closed position relative to the housing to an open position relative to the housing and vice versa. The method may also include mechanically coupling a purchase of the latch to the body such that the purchase is rotatable relative to the body about an axis parallel to the plane in which the body rotates relative to the housing such that the purchase is rotatable from a first position relative to the body to a second position relative to the body and vice versa, such that when in the second position, the purchase provides a mechanical advantage for removal of the information handling resource from an information handling system.
Technical advantages of the present disclosure may be readily apparent to one skilled in the art from the figures, description and claims included herein. The objects and advantages of the embodiments will be realized and achieved at least by the elements, features, and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are examples and explanatory and are not restrictive of the claims set forth in this disclosure.
A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:
Preferred embodiments and their advantages are best understood by reference to
For the purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a personal digital assistant (PDA), a consumer electronic device, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic. Additional components of the information handling system may include one or more storage devices, one or more communications ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communication between the various hardware components.
In this disclosure, the term “information handling resource” may broadly refer to any component system, device or apparatus of an information handling system, including without limitation processors, buses, memories, input-output devices and/or interfaces, storage resources, network interfaces, motherboards, electro-mechanical devices (e.g., fans), displays, and power supplies.
As shown in
Although not shown in the figures, in some embodiments, a spring may be mechanically coupled between bearing 206 and latch 204 in order to bias latch 204 in the closed position, thus returning latch 204 to the closed position after use (e.g., in the absence of a force applied to the latch to overcome the spring force).
Further, as shown in
In some embodiments, spring 216 may be configured to mechanically bias purchase 214 in the first position relative to latch 204, such that purchase 214 may be translated to a second position relative to latch 204 under a force applied (e.g., by a person) to purchase 214 that overcomes a spring force of spring 216.
When purchase 214 is translated to the second position relative to latch 204, purchase 214 may give a person a mechanical advantage for removing information handling resource 102 from chassis 100. For example, by applying a mechanical force to purchase 214 in a direction normal to face 202, the person may apply a sufficient force to overcome the mechanical forces that retain information handling resource 102 within chassis 100, and information handling resource 102 may slide out from chassis 100.
When in the open position, and whether or not purchase 214 is in its first position or second position, latch 204 may also be used as a feature (e.g., a handle) to allow a person to carry and/or lift information handling system 102 when it is removed from chassis 100.
As used herein, when two or more elements are referred to as “coupled” to one another, such term indicates that such two or more elements are in electronic communication or mechanical communication, as applicable, whether connected indirectly or directly, with or without intervening elements.
