Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1-5 As shown, the utility model is an intelligent electric heating glass controller, comprising an upper shell 1, a PCB board 2, a lower shell 3 and a circuit board 4; the upper shell 1 is detachably mounted above the lower shell 3, the PCB board 2 and the circuit board 4 are both mounted on the lower shell 3, and the upper shell 1 covers the PCB board 2 and the circuit board 4;

[0034] The left and right ends of the upper side of the lower shell 3 are formed with hinge grooves 5, and right-angled inner buckles 6 are rotatably installed in the hinge grooves 5. Pressure plates 7 are placed on the left and right edges of the upper side of the PCB board 2. The pressure plates 7 are arranged on the bottom sides of the right-angled inner buckles 6 in a one-to-one correspondence. A spring 8 is installed between the pressure plates 7 and the right-angled inner buckles 6;

[0035] The outer sides of the two right-angle inward buckles 6 are formed with buckles 9, and the left and right sides of the upper shell 1 are formed with slots 10, and the buckles 9 are buckled and installed in the slots 10 in a one-to-one corresponding manner;

[0036] The principle is: after the upper shell 1 is assembled, the spring 8 will drive the right-angled inner buckle 6 to rotate outward, and then allow the buckle 9 to be buckled into the slot 10, thereby completing the installation and fixation of the upper shell 1. When disassembling the upper shell 1, you only need to push the two right-angled inner buckles 6 inward to allow the buckle 9 to disengage from the slot 10. There is no need to pry for disassembly, which is convenient for actual use. The buckle 9 and the slot 10 will not be easily damaged, and their service life is increased. At the same time, after the upper shell 1 is installed, the spring will drive the pressure plate 7 to press the PCB board 2, thereby ensuring the stable installation of the PCB board 2. The PCB board 2 will not shift when it accidentally falls, and no screws are required for installation.

[0037] Furthermore: square openings 11 are formed on both ends of the top side of the upper shell 1, and the square openings 11 are arranged one by one above the right-angled inward buckle 6; the square openings 11 can be used to directly press the right-angled inward buckle 6 through the upper shell 1, thereby facilitating the disassembly of the upper shell 1.

[0038] Furthermore, a cover plate 12 is hingedly installed on the side of the square opening 11, and the cover plate 12 covers the square opening 11, making the whole more flat and beautiful.

[0039] Furthermore: a rotating shaft 13 is formed on the bottom side edge of the right-angle inward buckle 6, and the right-angle inward buckle 6 is installed in the hinge groove 5 by rotating through the rotating shaft 13. A torsion spring 14 is installed on the rotating shaft 13, and one end of the torsion spring 14 is installed in the hinge groove 5, and the other end of the torsion spring 14 is installed on the right-angle inward buckle 6; the spring 8 and the torsion spring 14 can be used to simultaneously provide the right-angle inward buckle 6 with power to rotate outward, thereby ensuring that after the upper shell 1 is installed, the buckle 9 can be stably inserted into the card slot 10, will not loosen on its own, and has high stability.

[0040] Furthermore, a board groove 15 is formed on the upper side of the lower shell 3, and the PCB board 2 is installed in the board groove 15 with a clearance fit, so that the installation and positioning of the PCB board 2 is more accurate.

The positioning cylinders 16 are installed in the positioning holes 17 with clearance fit, which can ensure the installation and positioning of the PCB board 2.

[0042] Furthermore: a conical buckle 18 is formed at the upper end of the positioning cylinder 16, and a groove 19 is formed in the middle of the upper side of the conical buckle 18; when the positioning hole 17 is installed into the positioning cylinder 16, the conical buckle 18 will shrink inward through the groove 19, and after being installed in place, the conical buckle 18 will recover, allowing the PCB board 2 to be snapped into the bottom side of the conical buckle 18, completing the stable installation of the PCB board 2.

[0043] Furthermore: there are at least two springs 8 between the pressure plate 7 and the right-angle inward buckle 6; this can ensure the stability of the right-angle inward buckle 6 during rotation, and prevent deviation and tilting.
