Patent number: 11700706Abstract: A riser of an information handling system having an adjustable baffle that blocks air flowing through the riser from by-passing components of an expansion card, such as a PCIe card, installed in the riser. The baffle directs the flowing air across components of the expansion card to lower the operating temperature of the expansion card by convection. In some embodiments, part of the baffle is coupled to an angled slot of the riser body and another part of the baffle is coupled to a card holder so that movement of the card holder automatically adjusts the position of the baffle to direct otherwise by-passing air toward the components of the installed expansion card.Type: GrantFiled: October 8, 2020Date of Patent: July 11, 2023Assignee: Dell Products L.P.Inventors: Chuan Chieh Tseng, Ming-Hui Pan

Publication number: 20190104635Abstract: A bezel lock system includes a bezel, convert bracket (CB), and lock. The bezel attaches to a chassis panel. The CB slideably secures a latching bracket (LB) of the bezel to a chassis, when in a locked position. The CB slides a length of a release gap along a transverse path from the locked position to a released position. The lock restricts removal of the bezel from the chassis when the lock is engaged in a locked orientation (LO). The lock includes a cam bracket (CamB) that rotates between locked and unlocked orientations. In the LO, the CamB constrains the CB from moving inward on the path by abutting the CB; CB is confined between the LB and CamB. In the unlocked orientation, the CamB is disposed out of the CB's path, allowing the CB to retract inward to the release position, which allows the bezel to detach from the panel.Type: ApplicationFiled: September 29, 2017Publication date: April 4, 2019Inventors: HSU-CHU WANG, CHUAN-CHIEH TSENG

Patent number: 8937814Abstract: A positioning structure for positioning a plate-shaped structure having at least one positioning hole is disclosed. The positioning structure includes at least one positioning element corresponding to the positioning hole, and the positioning element includes a placement portion for supporting the plate-shaped structure and a positioning portion extending toward a direction far away from the placement portion to form a hollow cylinder shape, and the positioning portion has an outer surrounding surface and a plurality of inner threads. Hence, when the outer surrounding surface of the positioning portion of the positioning element is inserted into the positioning hole to contact with the inner surface of the positioning hole, the positioning portion of the position element can be positioned in the positioning hole, thus the instant disclosure can be used to accurately position and secure the plate-shaped structure.Type: GrantFiled: July 13, 2012Date of Patent: January 20, 2015Assignees: Lite-On Electronics (Guangzhou) Limited, Lite-On Technology CorporationInventors: Chun Tang Tu, Chuan-Chieh Tseng, Yung-Lung Liu

Patent number: 8693182Abstract: A fixing mechanism for storage device includes a frame, and a detent component. One sidewall of the frame has a latch member. The detent component is movably disposed on the sidewall of the frame, and has a pressing component and an operating component. The operating component is disposed with at least one stop block. When the operating component is moved relative to the frame to a press position, the pressing component pushes the latch member to engage with the storage device, the stop block is embedded in the frame, and the detent component is held in the press position. Accordingly, the storage device may be fixed to the frame rapidly without using any screw, the operating procedure is dramatically simplified, and the space occupied by the fixing mechanism and the manufacturing cost are reduced.Type: GrantFiled: August 31, 2011Date of Patent: April 8, 2014Assignees: Lite-On Electronic (Guangzhou) Limited, Lite-On Technology CorporationInventors: Po-Hsiu Kuo, Chih-Li Liu, Yung-Lung Liu, Chuan-Chieh Tseng
