A locking bar and a knob are respectively provided at both ends of the rotating shaft. The knob is located on the outside of the cover, and the locking bar is located on the inside of the cover. A locking plate is provided inside the box corresponding to the position of the locking bar. The locking plate is provided with a locking groove for the lower part of the locking bar to be screwed in / out.

[0008] Rotate the knob to the unlock position. The knob will drive the rotating shaft to rotate, which in turn will cause the locking bar to rotate so that the lower part of the locking bar is rotated out of the locking groove. At this point, the cover and the box will be unlocked.

[0009] Preferably, an expansion module is provided between the high-voltage interface and the air pump interface. The expansion module includes an expansion board, which is detachably connected to the housing. The expansion board is provided with a low-voltage interface.

[0010] The low-voltage interface is electrically connected to the vehicle's lithium battery system, allowing users to charge mobile phones, MP3 players, and other electronic devices via the low-voltage interface.

[0011] Preferably, the expansion board is also equipped with a switch for controlling the power on / off of the low-voltage interface.

[0012] Preferably, the opening of the box body is provided with a waterproof groove along the outer edge, and the cover body is provided with a sealing ring that extends into the waterproof groove at the corresponding position.

[0013] When the cover and the box are locked together, the sealing ring on the cover extends into the waterproof groove at the opening of the box to waterproof and seal the power interface, expansion module and air pump interface inside the cover and the box.

[0014] The beneficial effects of this utility model are: the external tail box device is set on the vehicle body, so the user can use it without opening the vehicle body; the locking module can lock / unlock the cover and the box; the sealing ring can waterproof and seal the high-voltage interface, expansion module and air pump interface inside the box when the cover and the box are locked.

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example: An external tailgate device for automobiles according to this example, such as... Figures 1 to 4 As shown, it includes a cover 1, a locking module 2, and a box 3 installed on the vehicle body. The cover 1 covers the opening of the box 3, and the top of the cover 1 is hinged to the top of the box 3. The box 3 is provided with a high-voltage interface 4 and an air pump interface 5.

[0022] The locking module 2 includes a rotating shaft 21, which passes through the cover 1 and is perpendicular to the cover. The two ends of the rotating shaft 21 are respectively provided with a locking strip 22 and a knob 23. The knob 23 is located on the outside of the cover 1, and the locking strip 22 is located on the inside of the cover 1. The box 3 is provided with a locking plate 31 corresponding to the position of the locking strip 22. The locking plate 31 is provided with a locking groove 311 for the lower part of the locking strip 22 to be screwed in / out.

[0023] An expansion module 6 is provided between the high-voltage interface 4 and the air pump interface 5. The expansion module 6 includes an expansion board 61, which is detachably connected to the box 3. The expansion board 61 is provided with a low-voltage interface 62.
