[0002] Storage devices are devices used to store information, usually by digitizing information and then storing it in electrical, magnetic or optical media. With the development of electronic information technology, the storage and dissemination of information has completely broken the traditional situation of storing and disseminating information on paper carriers, and can present more and faster network information and data to users. In order to share and use electronic resources more conveniently and quickly, electronic information storage devices such as USB flash drives and mobile hard drives are indispensable.

[0003] The chip port position of traditional portable storage devices is particularly important, and they are often protected by adding caps. However, it is troublesome to remove the caps when using them, and the caps need to be separated from the body, so the caps are often lost. As a result, the chip ports cannot be protected for a long time, causing the chip ports to rust and age and fail to work properly. Traditional portable storage devices tend to generate a lot of heat when working. Being in a high temperature environment for a long time will accelerate the aging process of the storage devices, shorten their service life, affect the stability and work efficiency of the electronic components and controllers of the storage devices, and may cause the device to run slower, increase data reading and writing errors, and even cause the device to crash or be damaged.

[0004] The above-mentioned traditional storage devices may have problems such as being unable to protect the chip port for a long time. For this reason, we have proposed a portable data storage device. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a portable data storage device, aiming to improve the problem that the chip port cannot be protected for a long time.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3The utility model provides an embodiment: a portable data storage device, comprising a shell 1, the shell 1 plays a role in protecting the internal chip terminal 2, the inner wall of the shell 1 is fixedly connected to the limiting shaft 9 on both sides, the limiting shaft 9 plays the role of limiting the rolling curtain 8, so that the rolling curtain 8 will not block the movement of the chip terminal 2, the outer wall of the limiting shaft 9 is provided with a rolling curtain 8, the rolling curtain 8 plays the role of closing the shell 1, so that the data storage device has good dustproof performance, the two sides of the rolling curtain 8 are slidably connected to the slide groove 12, the slide groove 12 plays the role of limiting the rolling curtain 8 to move only inside the slide groove 12, the outer wall of the shell 1 is provided with a pushing block 5 on both sides, the pushing block 5 protrudes from the side of the shell 1, and plays the role of facilitating the pushing of the pushing shaft 10, the inner wall of the pushing block 5 is fixedly connected to the pushing shaft 10, the outer wall of the pushing shaft 10 is fixedly connected to the inside of the chip terminal 2, the chip terminal 2 can be pushed by the pushing block 5, and the lower part of the outer wall of the pushing shaft 10 is fixed near the pushing block 5 The roller shutter 8 is fixedly connected with a connecting block 11, and the bottom surface of the connecting block 11 is fixedly connected to the outer wall of the roller shutter 8. When the pushing block 5 is pushed to slide the chip end 2, the connecting block 11 can be used to slide the roller shutter 8 at the same time to achieve the purpose of linkage. A heat sink 7 is fixedly connected to the front of the connecting block 11. The heat sink 7 runs through the lower surface of the shell 1. The heat sink 7 absorbs the heat of the chip end 2. A heat sink 13 is provided on the lower surface of the heat sink 7. The heat sink 13 can increase the surface area of ​​the heat sink 7, thereby increasing the area in contact with the air and increasing the heat dissipation effect. Through grooves 4 are provided on both sides of the outer wall of the shell 1. The through grooves 4 limit the sliding of the driving shaft 10 and the limit block 6 only inside the through grooves 4. The limit blocks 6 are fixedly connected to both sides of the middle part of the chip end 2. The limit blocks 6 fix and support the front of the chip end 2. The limit blocks 6 are slidably connected to the inner wall of the through groove 4, and the side of the driving shaft 10 close to the pushing block 5 is slidably connected to the inner wall of the through groove 4.

[0024] The heat sink 7 and the heat sink block 13 are made of pure copper. Copper has good thermal conductivity, can quickly absorb the heat of the chip end 2 and quickly conduct the heat, and has good heat dissipation.

[0025] The outer wall of the pushing block 5 is affixed with a layer of anti-skid pad, which makes it easy to use the pushing block 5 to push the pushing shaft 10.

[0026] The material of the housing 1 is aluminum alloy. Aluminum alloy is light in weight and has good thermal conductivity, which makes the portable data storage device lighter and has better heat dissipation.

[0027] The rolling curtain 8 is made of rubber material, which can undergo large deformation, making it easier to fold the front end of the slide groove 12 into an angle.

[0028] The front end of the rolling curtain 8 is in an arc shape, and the arc shape has smaller resistance, which can make the rolling curtain 8 move more smoothly inside the sliding groove 12.

[0029] The upper surface of the heat sink 7 is in close contact with the lower surface of the chip terminal 2 , so that the chip terminal 2 can conduct heat to the inside of the heat sink 7 more directly.

[0030] A circular hole 3 is provided at a corner of the outer wall of the housing 1, and a rope can be passed through the circular hole 3 for easy carrying.

[0031] Working principle: push the pushing block 5 forward, thereby making the pushing shaft 10 move forward, thereby making the chip end 2 fixed on the outer surface of the pushing shaft 10 move forward, and at the same time, the connecting block 11 fixed on the lower surface of the pushing shaft 10 will pull the end of the rolling curtain 8 to form a linkage, so that the rolling curtain 8 shrinks from the front end of the shell 1 around the limiting shaft 9, and then the chip end 2 completely extends out of the shell 1, forming a working condition in which the chip end 2 extends and the rolling curtain 8 shrinks. When the chip end 2 is working, a large amount of heat will be generated, and the heat sink 7 arranged on the lower surface of the chip end 2 will absorb the heat, and then the heat sink 13 at the bottom will volatilize the heat into the air, so that the chip end 2 will not be overheated. After the chip end 2 finishes working, the pushing block 5 is used to collect the chip end 2 into the inside of the shell 1, and then the rolling curtain 8 is pushed out of the shell 1. When it reaches the front along the slide grooves 12 on both sides of the shell 1, the arc at the front end of the rolling curtain 8 makes it easier for the rolling curtain 8 to deform according to the slide grooves 12, and finally a sealed door is formed to protect the chip end 2.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
