Description

Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as limiting the utility model.

[0039] As shown in the drawings, Figures 1-2 The utility model discloses an embodiment of a button structure for cleaning equipment, including operation board 1, at least one operation button 2, button plate 3 and electrical device 4, wherein operation board 1, button plate 3 and electrical device 4 are sequentially arranged along the axial direction of electrical device 4, the axis of electrical device 4 is perpendicular to one reference surface in reference coordinate system 5, and operation button 2 is arranged on operation board 1 and is used to trigger button plate 3.

[0040] As shown in the drawings, Figure 1 Operation board 1 has an external shape surface 10, and the external shape surface 10 is not parallel to any reference surface in reference coordinate system 5. In order to maintain the beauty of the external shape surface 10 and prevent accidental triggering of operation button 2, the upper plane of operation button 2 is coplanar with the external shape surface 10 when operation button 2 is in an unpressed state.

[0041] In a possible implementation, the external shape surface 10 is perpendicular to one reference surface in reference coordinate system 5 and forms an acute angle with another reference surface.

[0042] As shown in the drawings, Figure 1 Reference coordinate system 5 is composed of front view reference surface 5-1, upper view reference surface 5-2 and right view reference surface 5-3 of the cleaning equipment, and it is well known that the front view reference surface 5-1, the upper view reference surface 5-2 and the right view reference surface 5-3 are all perpendicular to each other. The axis of electrical device 4 is perpendicular to the right view reference surface 5-3 and located on the front view reference surface 5-1. Preferably, the axis of electrical device 4 is also located on the upper view reference surface 5-2, that is, the intersection line of the axis of electrical device 4 and the front view reference surface 5-1 and the upper view reference surface 5-2 is coincident.

[0043] In a possible implementation, the profile surface 10 is arranged at an acute angle with the right-view reference surface 5-3. Preferably, the profile surface 10 is perpendicular to the front-view reference surface 5-1.

[0044] As shown in Figure 2 and Figure 3 , the profile surface 10 is concave towards the direction of the key plate 3 to form a recess 100 for accommodating the operation key 2, and the bottom wall of the recess 100 has a through hole 101 for the operation key 2 to pass through. The operation key 2 is movably arranged in the recess 100, and the pressing direction of the operation key 2 is perpendicular to the profile surface 10, so as to conform to the operation habit of the user and ensure that the user has a better pressing feeling. Specifically, the operation key 2 is provided with a hook for preventing the operation key 2 from falling off from the profile surface 10 through the through hole 101.

[0045] However, generally, the key plate 3 is arranged perpendicular to the axis of the electrical device 4, and since the profile surface 10 is arranged at an angle with the right-view reference surface 5-3, the pressing direction of the operation key 2 cannot form a perpendicular relationship with the key plate 3, which requires the user to press a larger stroke, thereby bringing the user a poor pressing feeling, which is not desirable in actual use.

[0046] In the present application, the key plate 3 is arranged inside the operation plate 1 and is provided with trigger protrusions 30 corresponding to the operation keys 2, and the key plate 3 is arranged parallel to the profile surface 10. When the user presses the operation key 2, the operation key 2 partially passes through the through hole 101 and presses the trigger protrusions 30, and by arranging the key plate 3 parallel to the profile surface 10, the pressing direction of the operation key 2 is perpendicular to the profile surface 10, so that the pressing direction of the operation key 2 is perpendicular to the key plate 3, thereby ensuring that the user has a better pressing feeling.

[0047] As shown in Figure 2 , the electrical device 4 is arranged inside the operation plate 1, and the key plate 3 is fixed on the electrical device 4. As shown in Figure 4 , in the present embodiment, the electrical device 4 is provided with a top surface 400 for supporting the key plate 3, and since the profile surface 10 is not parallel to any reference surface in the reference coordinate system 5, in order to make the key plate 3 parallel to the profile surface 10, the top surface 400 is arranged parallel to the profile surface 10.

[0048] In a possible implementation, as shown in Figure 2As shown, the electrical device 4 includes a cover plate 40 provided with the top surface 400 described above, a rear cover 41 and a motor 42, an axis of the motor 42 is perpendicular to one reference surface in the reference coordinate system 5, and the rear cover 41 and the cover plate 40 are sequentially arranged at the end of the motor 42. In the embodiment, the axis of the motor 42 is perpendicular to the right view reference surface 5-3 in the reference coordinate system 5, that is, the axis of the motor 42 is parallel to the axis of the electrical device 4, and the arrangement direction of the motor 42, the rear cover 41 and the cover plate 40 is perpendicular to the right view reference surface 5-3.

[0049] As shown, the key plate 3 is fixed between the cover plate 40 and the rear cover 41, and the top surface 400 of the cover plate 40 is provided with an opening 401 to expose the trigger bump 30, and the cover plate 40 and the rear cover 41 are fixedly connected by buckling. Specifically, the outer peripheral wall of the rear cover 41 is provided with a clamping block 412, and the cover plate 40 is provided with a hanging ear 405, and the hanging ear 405 is provided with a clamping hole 406 matched with the clamping block 412.

[0050] Further, as shown in Figure 2 and Figure 4 As shown, the rear cover 41 is provided with at least one support sleeve 410 extending towards the cover plate 40 for supporting the key plate 3, and the end of the support sleeve 410 close to the key plate 3 has an inclined surface 411, which is arranged parallel to the outer shape surface 10, and the inclined surface 411 abuts against the side of the key plate 3 away from the cover plate 40.

[0051] In the embodiment, the support sleeve 410 has a plurality of inclined surfaces 411, and the plurality of inclined surfaces 411 of the plurality of support sleeves 410 are located on the same plane to ensure that the plurality of support sleeves 410 simultaneously support the key plate 3.

[0052] Since the key plate 3 is parallel to the outer shape surface 10, the end of the support sleeve 410 close to the key plate 3 is provided with an inclined surface 411 parallel to the outer shape surface 10, so that the inclined surface 411 of the support sleeve 410 and the side of the key plate 3 away from the cover plate 40 are better fitted, to ensure the stability of the key plate 3 installation structure.

[0053] In this way, the key plate 3 is fixed on the top surface 400 of the cover plate 40 on the one hand, and is supported by the inclined surface 411 of the support sleeve 410 of the rear cover 41 on the other hand, which ensures that the key plate 2 can remain stable under the high frequency and high intensity pressing of the user, thereby avoiding the failure of the user's key pressing.

[0054] In the application, the motor 42 axis is perpendicular to one reference plane in the reference coordinate system 5, thus, the original arrangement of the electrical device 4 of the cleaning equipment is not changed, and the parallelism between the key plate 3 and the outer shape surface 10 is realized by setting the top surface 400 of the cover plate 40 and the inclined surface 411 of the supporting sleeve 410 to be parallel to the outer shape surface 10, and then the pressing direction of the key 2 is ensured to be perpendicular to the outer shape surface 10, so that the user has a better pressing feeling.

[0055] As shown in Figure 6 , the side of the cover plate 40 facing the key plate 3 is concave to form a mounting groove 402 for mounting the key plate 3, and the inner bottom wall 403 forming the mounting groove 402 is arranged in parallel with the top surface 400 of the cover plate 40.

[0056] As shown in Figure 6 , the side of the cover plate 40 facing the key plate 3 is convex to form a plurality of rib blocks 404, and the plurality of rib blocks 404 are distributed around the key plate 3 for limiting the key plate 3 to avoid dislocation of the key plate 3.

[0057] Further, the key plate 3 is fixed on the cover plate 40 by screws to further stabilize the key plate 3 and avoid dislocation of the key plate 3.

[0058] As shown in Figure 2 and Figure 5 , the rear cover 41 is located on the side of the key plate 3 away from the cover plate 40 for supporting the key plate 3 to avoid bending of the key plate 3 under the pressing of the operation key 2, so as to play a protective role for the key plate 3.

[0059] In the installation of the embodiment, first, the key plate 3 is placed in the mounting groove 402 and fixed with the cover plate 40 by screws, and the trigger protrusions 30 on the key plate 3 are exposed from the opening 401 and higher than the top surface 400 of the cover plate 40, then the hanging ears 405 are buckled on the clamping blocks 412 to connect the cover plate 40 and the rear cover 41, and the back surface of the key plate 3 is fully abutted against the inclined surface 411 on the supporting sleeve 410. Then the operation plate 1 with the keys 2 installed is installed on the shell of the cleaning equipment, and the operation keys 2 and the trigger protrusions 30 are corresponded one by one.

[0060] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application.
