The present invention relates generally to a slider system, and more specifically to a top cover slider system for a computer chassis.
Computing systems, such as servers, include chassis that encloses components of a computing device. The chassis can be constructed in an automated assembly fashion, which provides a cheap and efficient method of manufacturing computing devices. Top covers typically include guide pins riveted to sheet metal where the rivets engage with a guide hole along the side of a base component of the chassis. As the size of the chassis increases, additional guide pins are needed to secure the top cover to the base component, which increases fabrication complexities.
Accordingly, there is a need for improved mechanisms for securing a top cover to a base component of a computer chassis.

The above summary is not intended to represent each embodiment or every aspect of the present disclosure. Rather, the foregoing summary merely provides an example of some of the novel aspects and features set forth herein. The above features and advantages, and other features and advantages of the present disclosure, will be readily apparent from the following detailed description of representative embodiments and modes for carrying out the present invention, when taken in connection with the accompanying drawings and the appended claims. Additional aspects of the disclosure will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments, which is made with reference to the drawings, a brief description of which is provided below.
The present disclosure, and its advantages, will be better understood from the following description of representative embodiments together with reference to the accompanying drawings. These drawings depict only representative embodiments, and are therefore not to be considered as limitations on the scope of the various embodiments or claims.
A chassis for a computing device is described that includes a base component and a top cover. The top cover includes stamped protrusions extending from one or more side slider structures and engaging with guide slots in the base component. The side slider structurers extend downwardly from a top surface of the top cover. The stamped protrusions are unitary one-piece structures with the one or more side slider structures. Each of the stamped protrusions further correspond to respective guide slots such that the stamped protrusions are positioned within corresponding guide slots when the base component and the top cover are in a mating position.
The top cover system for a computer chassis described by the present disclosure has improved strength, and is more streamlined, than traditional guide pin configurations for securing a top cover to a base component. For example, the present disclosure of stamped protrusions that extend from side slider structures of a top cover has a higher-strength than traditional guide pins because the stamped protrusion are formed into the same material (e.g., sheet metal) used to form the side slider structures, rather than being a separate component that is mechanically connected to the top cover system. The high-strength configuration using stamped protrusions means that the desired securing of the top cover to the base component of a chassis can be achieved with, for example, fewer stamped protrusions than would otherwise be needed for a top cover using traditional riveted guide pins. Furthermore, stamp protrusions allow flexibility on the positioning of the stamped protrusions on the side slider structure. For example, where a traditional riveted guide pin would typically fail, such as at or near an edge of the side slider structure, a stamped protrusion in a side slider structure of a top cover would have sufficient operating strength over the working life of the computing device.
Fabrication of stamped protrusions in a side slider structure of a top cover can occur using stamping or pressing techniques on, for example, a flat sheet of metal that forms the side slider structure. A stamping press with a tool and die surface can be used to form the metal into the desired stamped protrusion shape, such as the shapes depicted and described in more detail below in the context of

The guide slots 140 can have an upper wall 103, a lower wall 105, an opening portion 106, and an end portion 108. The guide slots 140 can be located along the exterior of opposing sides of the base component 120, in order to provide a plurality of locations for a top cover 110 to be linked or mated to the base component 120. Although three guide slots 140 are shown in
During the process of linking or mating the top cover 110 to the base component 120, the stamped protrusions 130 slide between an upper wall 103 and a lower wall 105 of the guide slots 140. The guide slot 140 has an opening portion 106, where the stamped protrusion 130 enters, and an end portion 108, where the stamped protrusion 130 comes to rest and cannot be slid further into the guide slot 140. In some implementations, the end portion 108 can have a width that is approximately the same as a diameter of a stamped protrusion 130. The guide slot 140 can, in some implementations, be tapered between the opening portion 106 and the end portion 108, such that the guide slot 140 eventually reaches a smaller diameter than a diameter of a stamped protrusion 130. This point can be referred to as a hard stop because the stamped protrusion 130 can go no further into the guide slot 140.

The stamped protrusions 430a-430c are effectively a metal shell stamped or pressed into the metal of side slider structures 450a-450c, and include closed ends 437a-437c on one side and an open end (not shown) on the other side that provides access to the hollow interior space (not shown) defined by the metal shell. In some implementations, the stamped protrusion 430a may be positioned centrally on the side slider structure 450a, about halfway between a top edge 451a and a bottom edge 452a. In some implementations, the stamped protrusion 430b may be positioned very close to a lower edge 452b of the side slider structure 450b. For example, the stamped protrusion 450b may be positioned in the lower half (e.g., stamped protrusion 430c) or lower third (e.g., stamped protrusion 450b) along the height of their respective side slider structures (e.g., side slider structure 450c, 450b).
At least a portion of the stamped protrusions 430a-430c can have a generally cylindrical main body 435a-435c. The generally cylindrical main bodies 435a-435c may have protrusions of varying heights from their corresponding side slider structure 450a-450c. For example, the generally cylindrical main body 435c has a protrusion of greater height from the side sliding surface 450c than that of the generally cylindrical main bodies 435a, 435b from the corresponding side slider structures 450a, 450b. In some implementations, the stamped protrusions 430a-430c may further have a generally hemispherical closed end 437a-437c extending from the generally cylindrical main body 435a-435c for engaging with a corresponding guide slot in the base component 120 (e.g., see guide slot 140 in
In some implementations, the stamped protrusions 430d, 430e can abut and/or define lower edges 452d, 452e of corresponding side slider structures 450d, 450e. The stamped protrusions 430d, 430e are initially stamped or pressed into the metal of the side slider structure 450d, 450e. The stamped protrusions 452d, 452e are then cut to create a half-shell shape with, for example, an open bottom 441d, 441e and an open side 442d, 442e that expose the respective hollow interior spaces 440d, 440e of the stamped protrusions 430d, 430e. The shape of stamped protrusion 430d is similar to the shape of stamped protrusion 430c, except that the stamped protrusion 430d is a half-shell (e.g., generally a half-cylinder with a half-hemispherical end). The shape of stamped protrusion 430e generally has a half-domed stadium shape.

A desirable aspect of the present technology is that stamped protrusions, such as the stamped protrusion 530, of a top cover system, can be arranged at a distance of less than 1.5 times the outside radius, r, from the lower edge 552 of the side slider structure 550. With this arrangement, the stamped protrusions still provide sufficient strength to maintain the mating position between the top cover system and the base component of a computer chassis.
