USB-Unified Serial Bus is a relatively new type of interface technology that has been widely used in the PC field in recent years. USB technology consists of three parts: a PC system with a USB interface, system software capable of supporting USB, and devices using a USB interface. "Unified Serial Bus" (USB 2.0) is a computer peripheral connectivity specification jointly developed by major players in the PC industry, including Compaq, Hewlett-Packard, Intel, Lucent, Microsoft, NEC and Philips. The USB 1.1 specification is widely used now, the speed (12Mbps) is about 100 times faster than the standard serial port, supports simultaneous connection of multiple devices, and has a real "plug and play" feature. Because of these benefits, USB is generally favored by peripheral manufacturers.

On the other hand, as a non-volatile storage medium, flash memory - FLASH, because of its incomparable data stability and adaptability to the environment, it is especially able to overcome the shortcomings of floppy drives and floppy disks with complex mechanisms and small storage capacity. At the same time, with the gradual reduction of semiconductor production costs, mobile memory based on USB interface technology and flash storage technology has been widely used. But existing this type of product, its part comprises USB interface, controller, flash memory unit, and controller is electrically connected USB, flash memory, and the exterior is provided with outer casing, and flash memory, controller are fixedly placed in casing, and USB connector The interface protrudes outside the housing. As any finished product, its capacity is fixed. When a large-capacity memory is required, a complete USB memory must be purchased; on the other hand, if any part of the flash memory or the controller fails, the entire USB memory must be discarded. memory. This is not only difficult to meet a variety of different requirements in practical applications, but also will inevitably result in waste.

Another object of the present invention is to provide a USB mobile memory that can be freely upgraded, expanded, and replaced with a storage medium, and its controller can be flexibly connected to other devices that need to be connected to a computer through a USB port.

For this reason, the present invention realizes above-mentioned purpose through following technical scheme:

A USB mobile memory that can be upgraded, expanded, and replaced with a storage medium at will. It includes a USB connector, a controller, and a flash memory. The components are combined with the body and electrically connected with the controller. The main body is equipped with a read-write status control switch.

The flash memory storage part and the main body are connected through a sliding guide groove, and the electrical connection is an elastic top-contact connection. Certainly, the flash memory storage component and the main body are plugged or elastically engaged with each other.

In addition, a detachable rear cover is provided at the rear of the housing of the main body, and the main body is provided with an accommodating cavity for flash memory components, and the flash memory is placed in the accommodating cavity.

Furthermore, the electrical connection between the flash storage component and the main body can be a common interface, such as a USB connector or SMMC.

According to needs, the back cover can be slid on the body or buckled on the body.

Compared with the prior art, the present invention has the following obvious advantages:

1. The memory can be upgraded and expanded at will, which is convenient for users, reduces costs and saves resources.

2. The flash memory of the memory can be used as an independent spare part, which is similar to the use relationship of the mobile phone battery with respect to the mobile phone, and the flash memory can be replaced.

3. It is very convenient to disassemble and install the flash memory components.

4. Since the USB interface and the controller of the present invention are standard open devices, the controller can also be connected to other components that need to be connected to the computer, such as wireless transmission equipment such as infrared receivers, IC card holders, etc.

Specific implementation methods :

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-10, the present invention is a USB mobile memory that can be freely upgraded, expanded, and replaced with a storage medium. It includes a USB connector 1, a controller 2, and a flash memory 4, wherein the USB connector 1 and the controller 2 are fixed The memory body 3 is integrated into one body, and the flash memory 4 is combined with the body 3 as a physically independent storage component, and is electrically connected with the controller 2, and standard protocol interfaces such as USB, I ² C, etc. can be used to complete data transmission between the electrical connections, such as It is a standard USB interface, and the electrical connection can be seen in Figure 11. Therefore, the storage parts can be replaced at will to meet different needs. For example, when the capacity of the flash memory 4 is not enough, it is only necessary to replace the flash memory 4 with a large capacity, or multiple flash memory components can be used, while the USB connector 1 and the controller 2 can still use one.
