Systems and methods for insertion of an information handling resource in an information handling system
View Patent ↗In accordance with embodiments of the present disclosure, a system may include a structural base, a handle mechanically coupled to the structural base, and a cam element mechanically coupled to the handle. The handle may be configured to translate between an open position and a closed position and vice versa relative to the structural base. The cam element may be configured to mechanically couple to a retention structure for retaining the system when the handle is in the closed position and during at least a portion of the translation of the handle, move at least partially in a direction opposite to that of the handle in response to translation of the handle.
1. A system comprising:
a structural base;
a handle mechanically coupled to the structural base configured to translate between an open position and a closed position and vice versa relative to the structural base;
a cam element mechanically coupled to the handle and configured to:
mechanically engage a retention structure for retaining the system when the handle is in the closed position; and
during at least a portion of the translation of the handle, move at least partially in a direction opposite to that of the handle in response to translation of the handle; and
an intermediate element coupled between the handle and the cam element, wherein the intermediate element comprises an L-member including a first arm extending from a pivot point and a second arm extending from the pivot point at a fixed angle relative to the first arm.
2. The system of claim 1 , wherein the fixed angle is an angle of approximately 90 degrees.
3. The system of claim 2 , wherein:
a first end of the L-member is mechanically coupled to a first bearing configured to engage an angled driver slot of the handle;
a second end of the L-member is mechanically coupled to a second bearing configured engage a drive slot of the cam element; and
the pivot point is mechanically coupled to the structural base via a rotational pivot such that during at least a portion of the translation of the handle, the angled guide slot causes the first end of the L-member to translate away from a center of the handle as the L-member pivots about the pivot point in response to translation of the handle causing the second end to move in a direction opposite to that of the handle.
4. The system of claim 3 , wherein the handle comprises a U-shaped member having two handle arms coupled to a crossbar extending between and substantially perpendicular to the handle arms, wherein each of the handle arms comprises a driver slot mechanically coupled to a respective intermediate element.
5. The system of claim 1 , further comprising an information handling resource mechanically coupled to the structural base.
6. The system of claim 5 , wherein the information handling resource comprises a memory riser.
7. The system of claim 5 , wherein:
the information handling resource comprises an electrical connector; and
mechanical coupling of the cam element to the retention structure maintains electrical coupling between the electrical connector and a corresponding second electrical connector.
8. The system of claim 5 , further comprising a heat pipe thermally and mechanically coupled to the structural base, such that the heat pipe conducts heat generated by the information handling resource to the structural base.
9. The system of claim 1 , further comprising a lockout feature mechanically coupled to the structural base and configured to:
at a point during translation of the handle from the closed position to the open position relative to the structural base, engage with the handle to prevent closure of the handle relative to the structural base; and
mechanically interact with a lockout-releasing feature causing the lockout feature to disengage from the handle to allow closure of the handle relative to the structural base.
10. A method comprising:
mechanically coupling a handle to a structural base such that the handle is configured to translate between an open position and a closed position and vice versa relative to the structural base;
mechanically coupling a cam element to the handle such that the cam element is configured to:
mechanically engage a retention structure, attached to a motherboard, for retaining the structural base when the handle is in the closed position; and
during at least a portion of the translation of the handle, move at least partially in a direction opposite to that of the handle in response to translation of the handle; and
mechanically coupling an intermediate element between the handle and the cam element, wherein the intermediate element comprises a continuous and rigid L-member including a first arm extending from a pivot point and a second arm extending from the pivot point at a fixed angle relative to the first arm.
11. The method of claim 10 , wherein the fixed angle is approximately a right angle.
12. The method of claim 11 , wherein the method further comprises:
mechanically coupling a first arm end of the L-member to a first bearing configured to engage an angled driver slot of the handle;
mechanically coupling a second arm end of the L-member to a second bearing configured engage a drive slot of the cam element; and
mechanically coupling the pivot point to the structural base via a rotational pivot such that during at least a portion of the translation of the handle, the angled guide slot causes the first end of the L-member to translate away from a center of the handle as the L-member pivots about the pivot point in response to translation of the handle causing the second end to move in a direction opposite to that of the handle.
13. The method of claim 12 , wherein the handle comprises a continuous and rigid U-shaped member having two handle arms coupled to a crossbar extending between and substantially perpendicular to respective ends of the handle arms and each of the handle arms comprises a driver slot coupled to a respective intermediate element.
14. The method of claim 10 , further comprising mechanically coupling an information handling resource to the structural base.
15. The method of claim 14 , wherein the information handling resource comprises a memory riser.
16. The method of claim 14 , wherein:
the information handling resource comprises an electrical connector; and
mechanical coupling of the cam element to the retention structure maintains electrical coupling between the electrical connector and a corresponding second electrical connector.
17. The method of claim 14 , further comprising thermally and mechanically coupling a heat pipe to the structural base, such that the heat pipe conducts heat generated by the information handling resource to the structural base.
18. The method of claim 10 , further comprising mechanically coupling a lockout feature to the structural base and configured to:
at a point during translation of the handle from the closed position to the open position relative to the structural base, engage with the handle to prevent closure of the handle relative to the structural base; and
mechanically interact with a lockout-releasing feature causing the lockout feature to disengage from the handle to allow closure of the handle relative to the structural base.
19. An information handling system comprising:
a chassis comprising one or more bays each configured to receive an information handling resource assembly, each bay having a retention structure, configured in a fixed position relative to the chassis, for retaining an information handling resource assembly; and
