Hard disk bracket and hard disk module

The invention discloses a hard disk bracket which comprises a left side plate, a right side plate and a composite front frame connected between the front end of the left side plate and the front end of the right side plate. The composite front frame comprises an air deflector used for ventilation, a mounting groove formed in one side of the air deflector and used for mounting keys, a connecting part arranged on the other side of the air deflector and used for mounting a handle, and a plurality of conductive contacts connected to the air deflector and used for making contact with a case hard disk frame to achieve electromagnetic shielding. And a plurality of ventilation holes are formed in the air guide plate. The composite front frame covers the functions of a front frame body and a shielding cover in the prior art, the number of parts is reduced, and the use amount of raw materials is reduced, so that the lightweight design of the hard disk bracket can be realized on the basis of not influencing inherent fun
