DETAILED DESCRIPTION

[0029] The present application will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and the structural, method or functional changes made by those skilled in the art based on these embodiments are included in the protection scope of the present application.

[0030] If the description of this invention involves orientation (e.g., up, down, left, right, front, back, outside, inside, etc.), then the orientations involved need to be defined. For example, "To clearly express the positions and directions described in this invention, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the definition can be based on the paper or other references. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not necessary.

[0031] like Figure 1 , Figure 2 As shown, a cover plate assembly structure for an electric operating mechanism is provided on the panel 1 of the electric operating mechanism and allows for sliding. The panel 1 is provided with an operating hole 2, and includes a cover plate 3 for covering the operating hole 2, a cover plate groove provided on the panel 1 or the cover plate 3, and a pushing part 5 provided on the cover plate 3. The pushing part 5 is used to drive the cover plate 3 to slide in the cover plate groove.

[0032] In this embodiment, as Figure 3 As shown, the cover plate slide groove is provided on the panel 1. The cover plate slide groove includes a first cover plate slide groove 401 and a second cover plate slide groove 402. The first cover plate slide groove 401 is away from the micro switch 11, and the second cover plate slide groove 402 is close to the micro switch 11.

[0033] In this embodiment, the pushing part 5 is a strip-shaped groove, and force is applied to the bottom or side wall of the strip-shaped groove to realize the movement of the cover plate 3.

[0034] In addition, the pushing part 5 can also be a protrusion extending upward based on the cover plate 3, and force is applied to the protrusion to realize the movement of the cover plate 3.

[0035] like Figure 3 , Figure 4 As shown, the panel 1 is provided with a limiting buckle assembly, and the cover plate 3 is provided with a positioning component that cooperates with the limiting buckle assembly. The positioning component is provided with a positioning groove. When the cover plate 3 is in the open or closed position, the position of the cover plate 3 is restricted by the limiting buckle assembly.

[0036] The limiting buckle assembly includes a positioning slide groove 601 disposed on the panel 1, and a buckle is disposed on one side of the positioning slide groove 601. The buckle includes a buckle member 602 extending into the positioning slide groove 601 and a spring groove 603 disposed next to the buckle member 602. In this embodiment, the spring groove 603 is the space between the buckle member 602 and the second cover plate slide groove 402.

[0037] like Figure 5 , Figure 6As shown, the positioning member further comprises a positioning protrusion 7 arranged at the lower part of the cover plate 3, the positioning protrusion 7 is a strip-shaped protrusion, a positioning groove is arranged on the surface of the positioning protrusion 7 in contact with the buckle member 602, the positioning groove comprises a first positioning groove 801 and a second positioning groove 802, the buckle member 602 can be clamped in the positioning groove and does not move under the action of external force.

[0038] In the embodiment, two circular-arc-shaped extending ends are arranged outward from both ends of the positioning groove, the width of the positioning protrusion 7 is smaller than the width of the positioning sliding groove 601, and there is a gap between the positioning protrusion 7 and the inner wall of the positioning sliding groove 601 on the side of the buckle member 602. This design makes the buckle member 602 only deformed under the action of external force in two extreme positions, i.e. the opening position and the closing position, so that the service life of the buckle member 602 is enhanced, the safety factor is improved, the external force required by the user is reduced, and the user is more labor-saving. At the same time, the volume of the positioning protrusion 7 is also saved, the material is saved, and the weight of the cover plate 3 is reduced. The circular-arc-shaped design of the extending end also makes the sliding of the positioning groove more smooth.

[0039] The opening position is defined as the position of the cover plate 3 when the buckle member 602 is clamped in the second positioning groove 802 so that the operation hole 2 is completely exposed, and the closing position is defined as the position of the cover plate 3 when the buckle member 602 is clamped in the first positioning groove 801 so that the operation hole 2 is completely blocked.

[0040] One end of the positioning sliding groove 601 communicates with the operation hole 2, and the communicating part is circular-arc-shaped transition, which is more conducive to the sliding of the positioning protrusion 7.

[0041] The end of the positioning protrusion 7 close to the operation hole 2 extends a dustproof protrusion 701 towards the buckle member 602, and the dustproof protrusion 701 is attached to the positioning sliding groove 601. When the cover plate 3 is in the opening position, there is no gap between the dustproof protrusion 701 and the positioning sliding groove 601, which improves the dustproof ability of the cover plate assembly structure and is convenient for installation.

[0042] An extending block is further arranged on the positioning protrusion 7, which is used to press other components (such as a circuit board) located below the cover plate 3 to prevent the movement of other components.

[0043] Sliding blocks are arranged on both sides of the cover plate 3 and matched with the cover plate sliding groove, the movement of the cover plate 3 is realized through the sliding of the sliding blocks in the cover plate sliding groove. In the embodiment, the sliding blocks are L-shaped and abut against the cover plate sliding groove, the sliding blocks comprise a first sliding block 901 and a second sliding block 902, the first sliding block 901 is away from the micro switch 11, and the second sliding block 902 is close to the micro switch 11.

[0048] When the cover plate 3 is moved to the closing position by applying external force to the pushing part 5, the second positioning groove 802 deforms the buckle 602 to the rebound groove 603, the second positioning groove 802 is gradually separated from the buckle 602, the positioning protrusion 7 continues to move to the closing position, the second slider 902 drives the contact piece 10 to move away from the micro switch 11, the contact slope 1001 of the contact piece 10 is separated from the micro switch 11 to make the micro switch 11 open, until the buckle 602 is clamped into the first positioning groove 801, and the positioning protrusion 7 cannot be separated from the limit without applying force to the pushing part 5, the micro switch 11 remains in the open state, and the remote control end circuit is connected.
