The utility model discloses a mounting bracket for computer hard disk, it through first card portion and second card portion on mounting bracket cooperation effect, realize mounting bracket and the quick dismounting effect of exempting from tool between casing, install first computer hard disk fixed on mounting bracket, then locate mounting bracket to the assembly position of casing, make first card portion pass through the first card mouth of casing after, translation mounting bracket makes first card portion and casing form locking, and second card portion inserts the second card mouth of casing to restrict first card portion displacement, when dismounting, first drive second card portion exits second card mouth, then reverse translation mounting bracket can. Overall simple and reliable structure, thoroughly avoid screw fixed and lead to operation tedious and thread damage risk, especially suitable for the scene of needing frequently replacing hard disk.

The utility model discloses a compact case structure, which comprises a case shell, a bearing plate arranged in the case shell, a main board arranged on the front side of the bearing plate, a hollow hole arranged on the bearing plate and corresponding to the main board, and a power supply cabin arranged below the main board, and is characterized in that a hard disk frame is fixedly arranged on one side of the case shell far away from the main board; a computer hard disk is fixedly installed on the side, located in the case, of the hard disk frame, L-shaped frames used for supporting the computer hard disk are symmetrically arranged on the hard disk frame, and a side face heat dissipation assembly is arranged on the side, corresponding to the hollowed-out holes, of the case shell. Air entering the box shell firstly penetrates through the hollowed-out holes and directly acts on the back face of the mainboard, cooling of the mainboard is actively assisted, high-temperature work of the mainboard is avoided, the service life of the mainboard is prolonged, and stable operation of a computer is guaranteed.

The invention relates to a notebook computer hard disk destruction trigger circuit and method and a notebook computer. The circuit comprises a notebook computer power supply end, a cover opening state detection module, a power supply control module, an embedded controller power supply end and a destruction signal trigger module. The cover opening state detection module generates a cover opening state signal, and the cover opening state signal is in a low level when the rear cover of the notebook computer is in a closed state and is in a high level when the rear cover of the notebook computer is in an open state. And the power supply control module controls the power supply end of the notebook computer to be conducted with the power supply end of the embedded controller after receiving the high-level cover opening state signal. And the destruction signal triggering module generates a low-level destruction signal after receiving the high-level cover opening state signal. And the embedded controller controls the hard disk to execute hard disk destruction operation after receiving the low-level destruction signal. The circuit has the advantages that when the rear cover of the notebook computer is not opened, the embedded controller is powered off, and the circuit power consumption is low.
