Please refer to Figure 4 to Figure 7 for the specific operation procedure.

Please refer to FIG. 4 first, which shows a stage after the user presses the pressing portion 230 in FIG. As shown in FIG. 4, the user presses the pressing portion 230 in the clockwise direction of the drawing to rotate the pressing portion 230 in the clockwise direction around the rotating shaft 210. At this time, the third protruding portion 240 and the fourth protruding portion 250 connected to the rotating shaft 210 also rotate in the clockwise direction along the rotating shaft 210 together with the pressing portion 230. The fourth protruding portion 250 of the switch module 200 rotates clockwise and abuts against the second protruding portion 150 of the door cover module 100, and applies force to the second protruding portion 150 to lift the plate body 130. . The third protruding portion 240 of the switch module 200 gradually moves away from the first protruding portion 140 during the clockwise rotation along the rotating shaft 210.

As shown in FIG. 4, in the present embodiment, in order to allow the fourth projecting portion 250 to more smoothly push the plate body 130, the fourth projecting portion 250 has an inclined design toward the surface of the plate body 130. That is, the surface of the fourth projection 250 facing the plate body 130 is not a flat plane. Specifically, the portion of the fourth projection 250 near the door shaft 120 is designed as a wedge portion 250a. In this way, in the process in which the fourth protruding portion 250 pushes the second protruding portion 150, the contact area between the two is relatively uniform and smooth. With the above design, wear of the second protrusion 150 and the fourth protrusion 250 can be avoided.

Next, please refer to Fig. 5, which shows a cross-sectional view of the next stage door cover switch mechanism 10 continuing from Fig. 4. Following the fourth figure, when the third protruding portion 240 rotates clockwise along the rotating shaft 210 and completely leaves the first protruding portion 140, the plate body 130 can freely reverse along the door axis 120. The clock direction rotates.

In the stage of FIG. 5, while pressing the pressing portion 230, the user can use the other hand to lift the board 130 to expose the opening in the housing 110 to achieve the opening function of the switch module 200. However, the second protruding portion 150 in the present embodiment further has a groove portion 150a with the plate body 130 at an end away from the door shaft 120, and the groove portion 150a matches the wedge portion 250a of the fourth protruding portion 250. . With the above arrangement, the user can smoothly open the plate body 130 without continuously pressing the pressing portion 230. Specifically, it can be explained with reference to FIG.

Figure 6 is a cross-sectional view showing the next stage door cover switch mechanism 10 continuing through Figure 5. As shown in Fig. 6, the wedge portion 250a of the fourth projection 250 is caught in the recess portion 150a of the second projection 150, so that the door cover switch mechanism 10 is in the pressed state. In the pressed state, the plate body 130 is in the second position, and the pressing portion 230 is in the pressing position. Specifically, at this time, the user can stop pressing the pressing portion 230. Although the reset member 220 applies a moment of counterclockwise rotation to the drawing surface 210, the wedge portion 250a is caught in the groove portion 150a, so that the rotating shaft 210 cannot be rotated by the reset member 220.

In Fig. 6, in order to make the groove portion 150a and the wedge portion 250a more perfect, the contour of the groove portion 150a coincides with the wedge portion 250a. Specifically, the contour of the groove portion 150a is also wedge-shaped, and the wedge shape has an angle exactly equal to the angle of the wedge portion 250a. In other embodiments, the angles need not be exactly equal, and those skilled in the art can adjust the contour relationship of the groove portion 150a and the wedge portion 250a according to practical needs.

As shown in Fig. 6, in the case where the wedge portion 250a is engaged with the groove portion 150a, the user can pull up the first projection portion 140 to lift the plate body 130. At this time, the second protruding portion 150 pushes the fourth protruding portion 250 to rotate clockwise in the direction of the drawing along the rotating shaft 210 until the wedge portion 250a is disengaged from the groove portion 150a. Because of the matching design of the groove portion 150a and the wedge portion 250a with each other, the contact area of both is large and smooth during the pushing process. With the above design, wear between the groove portion 150a and the wedge portion 250a can be avoided.

When the wedge portion 250a is completely separated from the groove portion 150a, the plate body 130 has not been interfered by the switch module 200 at all, and the user can freely rotate the plate body 130 at this time. At the same time, the reset member 220 rotates the rotating shaft 210 back to the initial position (as shown in FIG. 3).

Please refer to Figure 7, which shows the door cover switch in the open state. A cross-sectional view of the mechanism 10. When the user wants to return the board 130 to the fixed state as shown in FIG. 3, it is only necessary to push the board 130 along the door axis 120 in the clockwise direction. As shown in FIG. 7, the first protruding portion 140 moves in the clockwise direction along with the plate body 130 and abuts against the third protruding portion 240. Next, the first protruding portion 140 pushes the third protruding portion 240 to move the third protruding portion 240 in the clockwise direction of the drawing. While the third protruding portion 240 moves in the clockwise direction, the third protruding portion 240 gradually moves away from the first protruding portion 140. When the surfaces of the third protruding portion 240 and the first protruding portion 140 abut each other completely away from each other, the first protruding portion 140 is no longer blocked by the third protruding portion 240, and can smoothly enter the third protruding portion. 240 and the space held by the fourth projection 250. Subsequently, the reset member 220 returns the third projecting portion 240 and the fourth projecting portion 250 to the original position, at which time the door cover switch mechanism 10 returns to the fixed state shown in FIG.

As shown in FIG. 7 , in order to enable the first protrusion 140 to push the third protrusion 240 more smoothly, the two protrusions of the first protrusion 140 and the third protrusion 240 have a tilt design. . Specifically, the first convex portion 140 has a first inclined surface 140a on the surface close to the first surface 130a, and the third convex portion 240 has a second inclined surface 240a on the surface away from the rotating shaft 210. In the present embodiment, the first inclined surface 140a and the second inclined surface 240a are inclined at an angle. Specifically, referring to FIG. 3, the angle between the first surface 130a and the first inclined surface 140a is equal to the angle between the first surface 130a and the second inclined surface 240a. In this way, in the process in which the first protruding portion 140 pushes the third protruding portion 240, the contact area between the two is large and smooth. With the above design, wear of the first protruding portion 140 and the third protruding portion 240 can be avoided.

Designing the first projection by the door cover module of the door cover switch mechanism The third protruding portion and the fourth protruding portion corresponding to the second protruding portion and corresponding to the design of the switch module achieve the switching function of the door cover switching mechanism. And the inclined surface of the first protruding portion and the third protruding portion are matched to each other, so that the wear of both during the switching process is reduced. And by designing a wedge portion on the fourth protruding portion, designing a groove portion between the second protruding portion and the plate body, so that the user can press the wedge portion into the groove portion when the pressing portion is pressed to a certain position. Therefore, the user does not need to continuously press the pressing portion, and does not have to worry about the door panel falling back to the first position of the fixed state.
