Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1 to 12As shown, this utility model embodiment provides a foldable dual-screen protective case, including: a protective case body 1, a control host 2, and a foldable screen assembly 3. The protective case body 1 is used to protect internal components. The control host 2 is connected inside the protective case body 1 for processing information. The foldable screen assembly 3 includes a first display structure 31 and a second display structure 32 for displaying operation content. The first display structure 31 is electrically connected to the control host 2 and can rotate relative to the control host 2 for storage, so that when the first display structure 31 is powered on, it can be controlled by the control host 2. Furthermore, the first display structure 31 can rotate relative to the control host 2 for storage, allowing it to be folded and stored inside the protective case body 1 when not in use, thus protecting the first display structure 31, saving space, and improving the convenience of carrying the foldable dual-screen protective case. The second display structure 32 is electrically connected to the first display structure 31 in the longitudinal direction and can be rotated and folded onto the first display structure 31.

The width of the rotation limiting structure body 41 is designed to correspond to the width of the rotation limiting structure body 41. The second rotation connecting part 321 is provided with a second rotation connecting hole. One end of the second rotation connecting shaft 43 is connected to the second mounting fastener 322 through the second rotation connecting hole, so that the second display structure 32 can rotate around the axis of the second rotation connecting shaft 43. At the same time, the first protrusion 4111 divides the rotation limiting connecting groove 411 into a first mounting position 4112 and a second mounting position 4113, so that the first rotation connecting shaft 42 and the second rotation connecting shaft 43 are limited by the first mounting position 4112 and the second mounting position 4113, avoiding interference between the first rotation connecting shaft 42 and the second rotation connecting shaft 43 during rotation, thereby improving the stability of the first display structure 31 and the second display structure 32 during rotation.

[0044] Furthermore, the screen of the first display structure 31 is a capacitive touch screen. When the first display structure 31 is unfolded, the commander can directly perform click, swipe or zoom operations through multi-touch gestures, such as quickly switching the map interface or adjusting the information display area. Since the touch response of the capacitive touch screen does not require physical pressing, the commander can complete the touch input in a natural posture even when standing, reducing operation delay and improving the flexibility and convenience of the foldable dual-screen support box during use, thereby improving work efficiency.

[0045] Furthermore, the control host 2 is equipped with a main control module for processing information, a keyboard 22 for inputting content, and a mouse-like structure 23.
