The U-shaped groove 50 on the top of the lower shell 10 is connected to the installation groove 30. At the same time, heat dissipation holes 60 are provided on the side walls at both ends of the U-shaped groove 50, so that the heat generated by the U disk body 40 can be dissipated to the outside world, thereby reducing the heat of the U disk body 40 and avoiding heat accumulation, which affects the service life of the U disk body 40. At the same time, the U disk in this application is easy to carry.

[0023] See also Figure 2 and 3 A lower groove 110 is provided on the top of the lower shell 10, and an upper groove 210 is provided on the bottom of the upper shell 20. The lower groove 110 and the upper groove 210 are closed to form a mounting groove 30, and one end of each of them is open. When set, one end of the mounting groove 30 is open, so that after the U disk body 40 is inserted into the mounting groove 30, the interface at one end thereof can extend from the open end of the mounting groove 30 and be connected to the host interface. After the U disk body 40 is used, the interface of the U disk body 40 can be stored in the mounting groove 30 to achieve the purpose of protecting the interface.

[0024] See also Figure 1A through opening 220 is provided at the top of the upper groove 210, and a moving block 410 is fixedly installed on the top of the U disk body 40. The moving block 410 is arranged through the through opening 220. It should be noted that the moving block 410 can slide in the through opening 220, so as to facilitate the movement of the U disk body 40 through the moving block 410, so as to achieve the purpose of facilitating the extension and contraction of the interface of the U disk body 40. At the same time, the through opening 220 can achieve the purpose of limiting the moving block 410 to prevent the U disk body 40 from falling off from the mounting groove 30.

[0025] See also Figure 2 and 3 A plurality of through holes 70 are provided between the inner wall of the U-shaped groove 50 and the lower groove 110. In the specific configuration, the plurality of through holes 70 are respectively provided on the inner walls on both sides of the U-shaped groove 50, thereby increasing the connection area between the lower groove 110 and the U-shaped groove 50 to improve the heat dissipation effect.

[0026] See also Figure 3 A plurality of buffer pads 120 are respectively installed on the side walls at both ends of the lower groove 110, and the side walls of the U disk body 40 are arranged in sliding contact with the buffer pads 120. Specifically, the buffer pads 120 are elastic, so as to protect the U disk body 40. When the lower shell 10 and the upper shell 20 vibrate, the buffer pads 120 can alleviate the vibration effect on the U disk body 40. At the same time, through the setting of the buffer pads 120, there is a gap between the U disk body 40 and the side walls at both ends of the installation groove 30, and one end of the gap is opened, so as to further increase the heat dissipation capacity.

[0027] See also Figure 3-5 A plurality of first buffer bars 130 are installed at the bottom of the lower groove 110, and a plurality of second buffer bars 240 are installed at the top of the upper groove 210. The U disk body 40 is arranged in sliding contact with the first buffer bars 130 and the second buffer bars 240. When arranged, the first buffer bars 130, the second buffer bars 240 and the buffer pad 120 are used in combination to improve the protection effect of the U disk body 40, so as to reduce the damage to the U disk body 40 caused by severe vibration. In addition, by arranging the first buffer bars 130 and the second buffer bars 240, there are gaps between the top and bottom of the U disk body 40 and the top and bottom of the installation groove 30, and one end of the gap is opened, which can further improve the heat dissipation capacity.

[0028] See also Figure 3No., two T-shaped bars 140 are fixedly installed on the top of the lower shell 10, and two T-shaped slots 230 are opened at the bottom of the upper shell 20. The two T-shaped bars 140 are respectively inserted into the two T-shaped slots 230. It should be noted that one end of the two T-shaped slots 230 is opened, so that the T-shaped bars 140 can be inserted into the inside of the T-shaped slots 230 from the open ends to achieve the connection between the lower shell 10 and the upper shell 20, and at the same time facilitate the separation of the lower shell 10 from the upper shell 20.

[0029] See also Figure 3 The back side of the lower shell 10 is rotatably connected to a limit block 150, and the limit block 150 is arranged in sliding contact with the back side of the upper shell 20. In the specific arrangement, one end face of the limit block 150 is fixedly connected to a fixed shaft (not shown in the figure), and the fixed shaft is rotatably connected to the back side of the lower shell 10. At the same time, the limit block 150 and the back side of the upper shell 20 have a certain friction force, so that the limit block 150 will not rotate by itself, and it needs to be pushed by a person to rotate.

[0030] When the portable U disk is in use, the moving block 410 is pushed to make the U disk body 40 slide in the installation slot 30, so that the interface of the U disk body 40 extends from the installation slot 30 and is connected to the host interface. When data is transmitted, the electronic components inside the U disk body 40 generate heat, and the lower groove 110 is connected to the U-shaped groove 50 through a plurality of through holes 70, and the U-shaped groove 50 is connected to the external environment through the heat dissipation holes 60, so that the heat generated by the U disk body 40 is dissipated to the outside to improve the heat dissipation effect.

[0031] It should be noted that the specific model and specifications of the USB flash drive body 40 need to be selected and determined based on the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it will not be described in detail.

[0032] The power supply and principle of the USB disk body 40 are clear to those skilled in the art and will not be described in detail here.
