Description

Technical Field

[0001] The utility model relates to the technical field of hard disk boxes, in particular to a hard disk box. Background Art

[0002] A hard disk enclosure is a large-capacity mobile storage device that exchanges data with a computer or other terminal at high speed through a USB port. It can be used in desktop computers or notebook computers with USB ports and other devices that support USB.

[0003] A general hard drive enclosure can only store data on one hard drive.

[0004] However, when the data in the two hard disks need to be stored or transferred, two hard disk boxes and two data cables are required to be switched alternately to connect to a computer or other terminal.

[0005] That is, the operation is performed by constantly plugging and unplugging the data cable to switch to the corresponding hard disk box, which greatly increases the complexity of use and causes inconvenience.

[0006] Therefore, in the utility model patent application, the applicant carefully studied a hard disk box to solve the above problems. Utility Model Content

[0007] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide a hard disk box that is compatible with both NVME hard disks and HDD hard disks and has a wide range of applicability. Moreover, it has a high degree of integration and a simple circuit structure design, which greatly reduces the manufacturing cost of this product.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A hard disk enclosure includes a first bridge chip, a second bridge chip, a dual SATA bridge chip, and a USB hub for connecting to a PC;

[0010] The USB hub is respectively connected to the first bridge chip, the second bridge chip and the dual SATA bridge chip;

[0011] The first bridge chip and the second bridge chip are both connected to an M2 storage interface, and at least one of the two M2 storage interfaces is connected to an NVME hard disk;

[0012] The dual SATA bridge chip is connected to two SATA III interfaces, and at least one of the two SATA III interfaces is connected to a HDD hard disk.

[0013] As a preferred solution, the model of the first bridge chip is ASM2362.

[0014] As a preferred solution, the model of the second bridge chip is ASM2362.

[0015] As a preferred solution, the model of the dual SATA bridge chip is ASM1352R.

[0016] Compared with the prior art, the utility model has obvious advantages and beneficial effects, specifically:

[0017] It mainly achieves compatibility with NVME hard drives and HDD hard drives at the same time through the cooperation of the first bridge chip, the second bridge chip, the dual SATA bridge chip and the USB hub, and has a wide applicability; in particular, the dual SATA bridge chip has built-in dual SATA, a high degree of integration, and a simple circuit structure design, which greatly reduces the manufacturing cost of this product.

[0018] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
