Patent number: 7009836Abstract: A locking device is described. The locking device is utilized to lock and unlock a removable device and especially to be suitable for locking and unlocking the removable device of a notebook computer. The locking device has a latch, an elastic member and a sliding switch. The latch engages a fixing indention of the removable device to fix the removable device. The elastic member provides a force to push the latch forward and a recess for retracting the latch backward. The sliding switch utilizes a stud to glidingly couple to a sliding surface of the latch so that the movements of the sliding switch and the latch form a predetermined included angle, preferably of about 90 degrees.Type: GrantFiled: June 24, 2004Date of Patent: March 7, 2006Assignee: Quanta Computer, Inc.Inventor: Chao-Yuan Lo

Patent number: 7009837Abstract: An integrated locking device is described. The integrated locking device is utilized to lock and remove a removable device and is especially suitable in a notebook computer. The locking device has a latch, a first elastic device, a push arm, and a sliding switch. The latch locks a fixing indention of the removable device to fix the removable device. The first elastic device provides a force to push the latch moving forward and a space for the latch moving back. When the removable device is taken out, the sliding switch pushes the push arm first. Then, a slider of the push arm pushes a sliding inclined surface of the latch to withdraw the latch from the fixing indention. Subsequently, the push arm pushes the removable device outward for releasing the removable device. The movements of the sliding switch and the latch form an included angle, preferably about 90 degrees.Type: GrantFiled: June 24, 2004Date of Patent: March 7, 2006Assignee: Quanta Computer, Inc.Inventor: Chao-Yuan Lo

Patent number: 6762928Abstract: An automatic lifting apparatus for a liquid crystal display module of notebook computers is described. The automatic lifting apparatus comprises a latch hook, a latch button, a latch spring, a lifting plate, at least one lifting spring, and a housing. The latch hook fixes on a liquid crystal display module of the notebook computer. The others parts are positioned inside a base of the notebook computer for locking the latch hook. Furthermore, the lifting plate with the lifting spring power pushes the latch hook moving upward until the latch hook reaches about the height of the latch hook. Therefore, the automatic lifting apparatus can open the liquid crystal display module more efficiently and easily.Type: GrantFiled: August 19, 2002Date of Patent: July 13, 2004Assignee: Quanta Computer Inc.Inventor: Chao-Yuan Lo

Patent number: 6708370Abstract: A locking structure for a notebook computer with a main body and a monitor covering the main body. The locking structure includes a first support, a locking mechanism and a second support. The first support is set in the main body. The locking mechanism has a spring, a plug and a shaft. The spring is disposed in the first support. The plug is disposed on the spring. The shaft pivots to the first support and pushes against the plug. The shaft has a recess. The second support is set in the monitor and connected to the shaft of the locking mechanism. The plug is engaged in the recess by resilient force provided by the spring when the second support rotates to rotate the recess of the shaft onto the plug.Type: GrantFiled: October 29, 2002Date of Patent: March 23, 2004Assignee: Quanta Computer Inc.Inventors: Jr-Teng Shih, Chao-Yuan Lo

Publication number: 20030235031Abstract: A multipurpose changeable module of a notebook computer is described. The multipurpose changeable module has a removable device module and a module case to install the removable device module in the notebook computer. The module case is attached to a motherboard in the notebook computer. There is a predetermined space between the module case and the motherboard to allow mounting of electronic devices on the motherboard. Therefore, the space of the motherboard may be extended. The module case further comprises a switch, a connecting rod, a latch and a push arm to release the removable device module. Hence, the removable device module is easily installed and released from the notebook computer. The removable device module comprises a floppy disk drive, hard disk, CD-ROM drive, CD-RW drive, DVD drive or secondary battery.Type: ApplicationFiled: October 8, 2002Publication date: December 25, 2003Inventor: Chao-Yuan Lo
