[0030] In this technical solution, the microcomputer protection device includes a housing 6, a front cover 1, a liquid crystal display screen 4, a circuit board 5, and other electronic components, etc. The circuit board 5 and other electronic components are all installed in the housing 6. The liquid crystal display screen 4 is first installed and fixed on the back surface of the front cover 1 and electrically connected to the circuit board 5 in the housing 6, and then by installing and fixing the front cover 1 at the opening of the housing 6, the installation of the liquid crystal display screen 4 in the microcomputer protection device is realized.

[0031] Specifically, the connection and fixation between the liquid crystal display screen 4 and the front cover 1 are as shown in the figure. A display window 2 is provided on the front cover 1, and the size of the display window 2 is slightly smaller than the size of the liquid crystal display screen 4. A plurality of fixing buckles 3 are provided on the back surface of the front cover 1 along the Y direction, and the plurality of fixing buckles 3 protrude from the front cover 1 along the Y direction. The liquid crystal display screen 4 is installed at the display window 2. One side of the liquid crystal display screen 4 along the Y direction abuts against the inner wall of the front cover 1, and the other side abuts against the fixing buckle 3, thereby realizing the installation and fixation of the liquid crystal display screen 4 on the front cover 1. Then lead wires are drawn from the liquid crystal display screen 4 to be connected to the circuit board 5, and finally the front cover 1 is installed and fixed on the housing 6 by bolts to encapsulate the circuit board 5 and other electronic components, thereby realizing the installation of the liquid crystal display screen 4 in the microcomputer protection device.

[0032] In summary, by providing fixed buckles 3 on the back of the microcomputer cover 1 and arranging the liquid crystal screen 4 at the display window 2 and engaging and fixing it with the fixed buckles 3, the connection and fixation between the liquid crystal screen 4 and the microcomputer cover 1 are realized.

[0035] Furthermore, a plurality of fixed buckles 3 are respectively arranged on both sides of the display window 2 along the X direction.

[0036] In this technical solution, the arrangement of a plurality of fixed buckles 3 at the display window 2 can be on both sides of the display window 2 along the X direction, or on both sides of the display window 2 along the Z direction, or there are fixed buckles 3 on both sides of the display window 2 along both the X direction and the Z direction, as long as the snap - fit fixation of the liquid crystal screen 4 on the cover 1 can be achieved.

[0037] Preferably, a plurality of fixed buckles 3 are symmetrically arranged on both sides of the display window 2 along the X direction. While facilitating the lead layout between the liquid crystal screen 4 and the circuit board 5, it can also ensure that the liquid crystal screen 4 is evenly stressed when snap - fitted on the cover 1, enhancing the installation stability of the liquid crystal screen 4.

[0038] Embodiment 3:
