[0063] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] Figure 1 shows a schematic diagram of the structure of a switch assembly in the related art, Figure 2 Shows Figure 1 Schematic diagram of the structure of the moving parts in Figure 3 Shows Figure 1 Schematic diagram of the structure of the fixing parts. Figure 1-Figure 3 In the related art, the switch assembly includes a moving part a' and a fixed part b' that cooperate with each other. The moving part a' can slide on the fixed part b' along a set direction. The moving part a' is provided with a positioning part 1'. The fixed part b' is provided with a travel part 2' used in conjunction with the positioning part 1'. The positioning part 1' can move relative to the travel part 2' along the set direction to limit the travel displacement of the moving part a'. The fixed part b' is also provided with a sensing part 3', and the control function is realized by changing the position of the moving part a' on the fixed part b'.

[0065] In the related art, since the travel portion 2' is disposed on the fixing member b', the moving member a' needs to cover the travel portion 2' at each functional position, so that the moving member a' and the switch assembly are larger in size and there is room for improvement.

[0066] Based on the above technical problems, the present application provides a switch assembly and an electrical device, aiming to reduce the size of the switch assembly to at least a certain extent, so as to facilitate the development of the product in a more refined and compact direction.

[0067] Figure 4 shows a schematic diagram of the structure of the switch assembly in some embodiments, Figure 5 Shows Figure 4 Schematic diagram of the structure of the moving parts in Figure 6 Shows Figure 4 Schematic diagram of the structure of the fixing parts. Figure 4-Figure 6 The present application provides a switch assembly C, which includes a moving part a and a fixed part b that cooperate with each other. The moving part a can move along a set direction on the fixed part b. The moving part a is provided with a travel part 21 on the side of the fixed part b. The fixed part b includes a positioning part 4. The travel part 21 can move along the set direction on the positioning part 4.

[0068] The switch assembly provided in the present application has a travel portion 21 provided on the side of the moving part a facing the fixed part b, and the fixed part b includes a positioning portion 4. The positioning portion 4 can move along a set direction in the travel portion 21 to limit the travel displacement of the moving part b, thereby avoiding the technical problem in the related art that the travel portion for limiting the travel displacement is set on the fixed part b, resulting in the moving part a needing to cover the decorative travel portion, causing the moving part a to be larger in size. The size of the moving part a and the switch assembly can be reduced to a certain extent, so as to facilitate the development of the product in a more refined and compact direction.

[0069] In some embodiments, the size of the travel portion 21 of the moving part a in the set direction needs to be larger than the size of the positioning portion 4 on the fixed part b in the set direction, so that the moving part a can cover the decorative positioning portion 4 while also being able to move along the set direction to form at least two functional positions.

[0070] In some embodiments, a recess 21 may be provided on the side of the moving part a facing the fixed part b, and the recess 21 may be configured as the above-mentioned travel part 21.

[0072] Figure 7 A schematic diagram showing the dimensions of the switch assembly of the present application is shown. Figure 8 The schematic diagram of the dimensions of the switch assembly in the related art is shown. Figure 7 as well as Figure 8 , if the travel portion 21 of the setting moving part a has n key slots 211, the switch assembly C of the present application has n functional positions accordingly, n is greater than or equal to 2, and the length of each key slot 211 in the setting direction is h. Figure 7 As shown, the technical solution shown in the present application that the travel portion 21 is arranged on the moving part a is adopted, and the length dimension H1 of the moving part a in the set direction is approximately nh; Figure 8 As shown, the technical solution shown in the related art that the travel part 2' is set on the fixed part b' is adopted. Since the moving part a needs to cover the decorative travel part 2' at each functional position, the length dimension H2 of the moving part a' in the related art along the set direction must be greater than nh. That is, the length dimension of the moving part a along the set direction shown in the application must be greater than the length dimension of the moving part a' in the related art along the set direction. The present application can reduce the size of the switch assembly C to a certain extent, so as to facilitate the development of the product in a more refined and compact direction.

[0073] In other embodiments, the side of the moving part a facing the fixed part b may be provided with a plurality of convex parts, and the plurality of convex parts may be configured as the above-mentioned travel part 21.

[0107] In other embodiments, the third limiting portion 37 may also only include the above-mentioned movable channel 371 and transfer channel 372, the movable channel 371 extends from the opening side of the mounting groove 31 to the interior of the mounting groove 31, the transfer channel 372 and the movable channel 371 are connected, the transfer channel 371 can be arranged along the circumference of the mounting groove 31, the positioning protrusion 4 can enter into the transfer channel 372 through the movable channel 371, enter and position in the transfer channel 372, and the assembly of the protrusion 4 on the fixed seat 3 can also be realized.

[0108] In some embodiments, two third limiting portions 37 and two positioning protrusions 44 may be disposed relative to the central axis of the protrusion 4 . Figure 20-22 Shows Fig.19 The convex part is shown in the assembly diagram on the fixed seat. Figure 20-22 When the convex part 4 is assembled in the mounting groove 31, the positioning protrusion 44 on the convex part is first aligned with the top of 37 to form Fig. 20 The state shown in the figure is then pressed to move the positioning protrusion 44 of the protrusion 4 along 37 to the entrance end of the transfer channel to form Fig.21 In the state shown, the convex part 4 is rotated to make the positioning protrusion 44 of the convex part 4 rotate in the transfer channel until it is rotated into the positioning channel, and the pressing is released. Under the action of the elastic member 5, the positioning protrusion 44 of the convex part 4 is positioned at the top of the positioning channel 373, forming Fig. 22 In the state shown, the protrusion 4 can be assembled in the mounting groove 31, which is convenient and quick, and improves the assembly efficiency.

[0109] It should be noted that more third limiting portions 37 and positioning protrusions 44 may be provided correspondingly, which is not limited here.

[0110] Combination Fig.18 In some embodiments, the fixing seat 3 may include a fixing plate 35 and a second sleeve 38 disposed on the side of the fixing plate 35 facing away from the moving part a, and the interior of the second sleeve 38 may be configured as the above-mentioned mounting groove 31. Since the second sleeve 38 is disposed on the side of the fixing plate 35 facing away from the moving part a, the space between the fixing part b and the moving part a is not sufficient to mount the above-mentioned sensing part 6, and therefore, the sensing part 6 may be mounted on the side of the fixing plate 35 facing away from the moving part a.

[0111] Combination Fig.19 In some embodiments, a third guide member 45 may be connected to the bottom of the protrusion 4 , and a portion of the elastic member 5 is mounted on the third guide member 45 to provide guidance for deformation recovery of the elastic member 5 .

[0112] Combination Fig.18 , Fig.21 as well as Fig. 22 In some embodiments, a through hole 39 may be provided at the bottom of the mounting groove 31 , and a third guide member 45 at the bottom of the protrusion 4 may pass through the through hole 39 , and the elastic member 5 is disposed between the protrusion 44 and the bottom of the mounting groove 31 .

[0113] It should be noted that, in other embodiments, the bottom end of the elastic member 5 may extend out of the bottom of the mounting groove 31, and the elastic member 5 is supported by a component for loading the switch assembly C. In this case, the control body 1 may have a longer tactile travel to improve the user experience. In specific implementation, the bottom end of the elastic member 5 may be passed through the bottom through hole 39 of the mounting groove 31, which will not be described in detail here.

[0114] The switch assembly C shown in the present application is consistent in function with the switch assembly C in the related art, and both utilize the concave portion 21, the convex portion 4 and the elastic member 5 to cooperate with each other to achieve the gear suspension of the switch assembly C during the movement process. The main difference is that the present application assembles the elastic member 5 and the convex portion 4 on the fixed member b, and sets the concave portion on the moving member a, while in the related art, the elastic member 5 and the convex portion 4 are assembled on the moving member a, and the concave portion 21 is set on the fixed member b. While maintaining the same number and spacing of the key slots 211, the same size of the convex portion 4, and the same function of the control body 1, the size of the control body 1 of the switch assembly C has been greatly reduced, which has good practicality.

[0116] The electrical equipment having the above-mentioned switch assembly C has a stroke portion 21 provided on the side of the moving part a facing the fixed part b, and the fixed part b includes a positioning portion 4. The positioning portion 4 can move along a set direction in the stroke portion 21 to limit the stroke displacement of the moving part b, thereby avoiding the technical problem in the related art that the stroke portion for limiting the stroke displacement is set on the fixed part b, resulting in the moving part a needing to cover the decorative stroke portion, causing the moving part a to be larger in size. The size of the moving part a and the switch assembly can be reduced to a certain extent, which is conducive to the development of the product in a more refined and compact direction, and has good practicality.

[0117] In some embodiments, the carrier D may be a housing of an electrical device, and the fixing member b of the switch assembly C may be detachably connected to the carrier D, or integrated into the carrier D, which is not limited here.

[0118] Combination Fig.23 In some embodiments, a guide groove 7 may be provided on the carrier D, and the moving part a of the switch assembly C may slide in the guide groove 7 along a set direction. The width dimension of the guide groove 7 is adapted to the width dimension of the moving part a, and the length direction of the guide groove 7 needs to be larger than the length direction dimension of the moving part a, so that the moving part a can move in the guide groove 7 along the set direction.

[0119] In some embodiments, the electrical device may be a vacuum cleaner, or other electrical devices that require multiple functions, such as a hair dryer, a floor scrubber, etc., which is not limited here.
