Now, the structure of the vehicle-mounted pull-out hard disk box provided by the embodiment of the present invention will be described.

Please refer to FIG. 1 to FIG. 3 together. The vehicle-mounted pull-out hard disk box structure includes a fixing base 1 and a hard disk box 2 .

The fixing seat 1 is fixedly arranged and can be fixed inside the vehicle-mounted monitoring equipment. The hard disk box 2 is slidably connected in the fixed seat 1, and the hard disk box 2 can be drawn out relative to the fixed seat 1, so that the hard disk box 2 can be independently taken out from the vehicle monitoring equipment. The fixing seat 1 has a first clamping portion 11 , and when the hard disk case 2 is inside the fixing base 1 , the fixing base 1 is clamped and fixed in the fixing base 1 through the first clamping portion 11 .

Hard disk box 2 comprises box body 23, first cantilever part 21 and second cantilever part 22, and first cantilever part 21 and second cantilever part 22 are connected with box body 23 cantilever, and first cantilever part 21 and second cantilever part 22 can be deformed relative to the box body 23 . The second cantilever portion 22 is provided with a second engaging portion 27 for engaging with the first engaging portion 11 on the fixing seat 1 . When the hard disk case 2 is located in the fixing seat 1 and the first engaging portion 11 and the second engaging portion 27 are engaged, the hard disk case 2 is fixed in the fixing seat 1 . The first cantilever portion 21 has a first guiding surface 2131 , and the second cantilever portion 22 has a second guiding surface 221 . When the first cantilever part 21 is pressed, the first cantilever part 21 is deformed, and the first guide surface 2131 on the first cantilever part 21 and the second guide surface 221 on the second cantilever part 22 abut against each other, so that the second cantilever part 22 Deformation occurs, and the deformation of the second cantilever portion 22 disengages the second engaging portion 27 from the first engaging portion 11 , so that the hard disk case 2 can be pulled out. Because the vehicle-mounted pull-out type hard disk box structure is located in the vehicle-mounted monitoring device, the second cantilever portion 22 of the hard disk box 2 may be difficult to press due to space constraints. The pressing direction of the first cantilever portion 21 and the deformation direction of the second cantilever portion 22 It is set at an included angle. In this way, by pressing the first cantilever part 21 in the M direction, the first guide surface 2131 presses the second guide surface 221, so that the second cantilever part 22 is deformed in the N direction.
