Description

Hard disk carrier

This invention relates to a hard disk carrier assembly, and more particularly to a removable disk carrier assembly.

The existing easy-to-disassemble hard disk bearing assembly □ is easy to disassemble and is mostly designed with a non-locking disassembly mechanism, for example, a push-type cassette. If the easy-to-removable hard disk carrying component collides with objects in the process of falling from a height, or collides with the ground after colliding with it, the non-locking disassembly mechanism is prone to non-locking during the collision process. The disassembly mechanism of the type is excessively deformed, so that the components in the hard disk carrying assembly are at risk of being separated from each other. As a result, the hard disk carrying component after separation and detachment will not be able to protect the complete function of the hard disk, and expose the protected hard disk to the risk of damage.

Therefore, in order to prevent the components of the hard disk carrier assembly from being separated from each other, it is necessary to limit the amount of deformation of the non-locking type of disassembly mechanism, such as adding a limit structure to the counterpart of the non-locking type disassembly mechanism. However, placing the limit structure on the opponent member has problems in assembly, such as the tolerance between the opponent member and the non-locking disassembly mechanism, which may cause problems of mutual matching and installation. Even, it is considered that the easy-to-disassemble hard disk bearing assembly can be installed on different models, and there are differences between different models. Not every machine has enough space to install the opponent or set the limit on the opponent. structure.

It can be seen that the above existing architecture obviously has inconveniences and defects, and needs to be further improved. □Understanding the above-mentioned problems, the relevant fields have not tried their best to solve the problem, but the method that has not been applied for a long time has been developed. Therefore, how to effectively solve the above problems is one of the current important research and development topics, and it is also an urgent need for improvement in the relevant fields.

One aspect of the present invention is directed to a hard disk carrier assembly having a stop structure that is selectively movable between a bracket sidewall and a snap structure or between a bracket sidewall and a snap structure. When the stop structure is separated from the bracket sidewall and the snap-fit structure, the snap-fit structure can selectively engage the tab or move toward the bracket sidewall to disengage the tab. When the stop structure is moved between the side wall of the bracket and the engaging structure, the locking engagement structure is moved toward the side wall of the bracket such that the engaging structure cannot be disengaged from the bump. Since the blocking structure is located between the side wall of the bracket and the engaging structure, it can be avoided or reduced that when the hard disk carrying assembly is dropped, the engaging structure is disengaged from the bump due to the collision of the hard disk carrying assembly. In this way, the hard disk carrier member can be prevented or reduced from being detached from the housing member due to the collision of the hard disk carrier assembly, so that the hard disk protected in the hard disk carrier member is damaged.
