[0056] Figure 1 shows a schematic diagram of the structure of a switch assembly in the related art, Figure 2 shows a schematic diagram of the structure of the moving part in Figure 1, and Figure 3 shows a schematic diagram of the structure of the fixed part in Figure 1. Referring to Figures 1-3, 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 along a set direction on the fixed part b'. A positioning part 1' is provided inside the moving part a', and a travel part 2' that cooperates with the positioning part 1' is provided on the fixed part b'. The positioning part 1' can move relative to the travel part 2' along a set direction to limit the travel displacement of the moving part a'. A sensing element 3' is also provided on the fixed part b', and the control function is realized by changing the position of the moving part a' on the fixed part b'.

[0057] In related technologies, since the travel portion 2' is set on the fixed member b', the moving member a' needs to cover the travel portion 2' in every functional position, which makes the moving member a' and the switch assembly larger in size, leaving room for improvement.

[0058] In view of the above-mentioned technical problems, this disclosure provides a switch assembly and an electrical device, which aims to reduce the size of the switch assembly to at least a certain extent, so as to facilitate the development of products towards a more refined and compact direction.

[0059] Figure 4 shows a schematic diagram of the structure of a switch assembly in some embodiments, Figure 5 shows a schematic diagram of the structure of the moving part in Figure 4, and Figure 6 shows a schematic diagram of the structure of the fixing part in Figure 4. Referring to Figures 4-6, this disclosure provides a switch assembly including a moving part a and a fixing part b that cooperate with each other. The moving part a can move along a predetermined direction on the fixing part b. A travel portion 21 is provided on the side of the moving part a facing the fixing part b. The fixing part b includes a positioning portion 4, and the travel portion 21 can move along the predetermined direction on the positioning portion 4.

[0060] The switch assembly provided in this disclosure has a travel portion 21 on the side of the moving part a facing the fixed part b. The fixed part b includes a positioning portion 4, which can move in a set direction within the travel portion 21 to limit the travel displacement of the moving part b. This avoids the technical problem in related technologies where the travel portion limiting the travel displacement is set on the fixed part b, which requires the moving part a to cover the decorative travel portion and results in a large size of the moving part a. This reduces the size of the moving part a and the switch assembly to a certain extent, which is conducive to the development of products towards a more refined and compact direction.

[0061] In some embodiments, the dimension of the travel portion 21 of the moving member a in the set direction needs to be greater than the dimension of the positioning portion 4 on the fixing member b in the set direction, so that the moving member a can cover the decorative positioning portion 4 while also being able to move along the set direction to form at least two or more functional positions.

[0062] In some embodiments, the side of the moving member a facing the fixing member b may be provided with a recess 21, which may be configured as the aforementioned travel portion 21. Correspondingly, the fixing member b includes a protrusion 4, which moves in a predetermined direction within the recess 21 and is configured as the aforementioned positioning portion 4.

[0063] Referring to Figures 5 and 6, in some embodiments, the recess 21 includes a plurality of keyways 211 arranged sequentially along a set direction, and the protrusion 4 on the fixing member b can switch between the plurality of keyways 211 to form different functional positions.

[0064] Figure 7 shows a dimensional schematic diagram of the switch assembly of this disclosure, and Figure 8 shows a dimensional schematic diagram of a switch assembly in the related art. Referring to Figures 7 and 8, if the travel portion 21 of the moving member a has n keyways 211, the switch assembly of this disclosure correspondingly has n functional positions, where n is greater than or equal to 2, and the length of each keyway 211 in the setting direction is h. As shown in Figure 7, using the technical solution of the travel portion 21 of this disclosure being disposed on the moving member a, the length dimension H1 of the moving member a in the setting direction is approximately nh; as shown in Figure 8, using the technical solution of the travel portion 2' being disposed on the fixing member b' in the related art, since the moving member a needs to cover the decorative travel portion 2' in each functional position, the length dimension H2 of the moving member a' in the setting direction in the related art must be greater than nh. That is, the length dimension of the moving member a in the setting direction shown in this disclosure is necessarily greater than the length dimension of the moving member a' in the setting direction in the related art. This disclosure can reduce the size of the switch assembly to a certain extent, which is conducive to the development of products towards a more refined and compact direction.

[0065] In other embodiments, the side of the moving member a facing the fixed member b may have multiple protrusions, which can be configured as the aforementioned travel portion 21. Correspondingly, the fixed member b has a recess, and the multiple protrusions can move sequentially within the recess along a predetermined direction. The recess is configured as the aforementioned positioning portion 4. The specific structure and details of the switch assembly shown in this disclosure will now be further described, with the recess as the travel portion 21 and the protrusion as the positioning portion 4.

[0066] Referring to Figure 5, in some embodiments, three keyways 211 can be arranged sequentially along a set direction. When the moving part a moves relative to the fixed part b, the protrusion 4 on the fixed part b can be switched to the three keyways 211 respectively to form three functional positions, such as the power-off position, the power-on position, and the standby position.

[0067] In other embodiments, there may be two, four or more keyways 211 arranged sequentially along a set direction to form two, four or more functional positions, without limitation.

[0068] In some embodiments, the moving part a is a component for user operation and is typically positioned above the fixed part b. For ease of description, the following description will assume that the moving part a is positioned above the fixed part b; in other embodiments, if the moving part a is positioned in the horizontal direction or other directions of the fixed part b, the corresponding adjustments can be made, which will not be elaborated here.

[0069] Referring to Figure 5, in some embodiments, the moving part a may include a control body 1 and an assembly body 2. Figure 9 shows a schematic diagram of the control body in Figure 5. Referring to Figures 5 and 9, the bottom of the control body 1 is provided with a receiving groove 11, the assembly body 2 is connected to the receiving groove 11, and the recess 21 is provided on the side of the assembly body 2 facing the fixing member b, that is, the recess 21 is provided at the bottom of the assembly body 2. The control body 1 is a component used for control, and its surface may be smooth or have certain textures and / or protrusions. Its projection on the fixing member b may be oval. Correspondingly, the receiving groove 11 and the projection of the assembly body 2 on the fixing member b are also oval. The length direction of the oval can be the moving direction of the moving part a, so that while satisfying the condition of opening the recess 21, the size of the moving part a can also be reduced to a certain extent.

[0070] In some embodiments, the assembly 2 is detachably assembled into the receiving groove 11 of the control body 1, so that the control body 1 and the assembly 2 are manufactured separately, and the moving part a can be quickly disassembled and assembled in the event of an abnormality in the moving part a, so as to facilitate the maintenance of the switch assembly.

[0071] Figure 10 shows a structural schematic diagram of the assembly in Figure 5. Referring to Figures 5, 9, and 10, in some embodiments, the bottom of the receiving groove 11 may be provided with a first limiting part 12, and the assembly 2 is provided with a second limiting part 22 facing the bottom of the receiving groove 11. The second limiting part 22 and the first limiting part 12 are connected to each other to position the assembly 2 in the receiving groove 11, thereby providing positioning for the assembly 2 on the control body 1.

[0072] Referring to Figures 9 and 10, in some embodiments, the first limiting part 12 and the second limiting part 22 are nested together, one of which is a positioning post and the other is a positioning sleeve. The positioning sleeve can be fitted onto the positioning post to provide positioning for the assembly 2 on the control body 1.

[0073] Referring to Figures 9 and 10, in some embodiments, the first limiting part 12 can be a positioning post, which can be integrally formed on the bottom of the receiving groove 11. Correspondingly, the second limiting part 22 can be a positioning sleeve, which can be integrally formed on the assembly 2. The positioning sleeve is fitted onto the positioning post to provide positioning for the assembly 2 on the control body 1.

[0074] In other embodiments, the first limiting part 12 can be a positioning sleeve, which can be integrally formed on the bottom of the receiving groove 11. Correspondingly, the second limiting part 22 can be a positioning post, which can be integrally formed on the assembly 2. The positioning post gap is set in the positioning sleeve to provide positioning for the assembly 2 on the control body 1.

[0075] Referring to Figures 9 and 10, in some embodiments, the sidewall of the receiving groove 11 may be provided with two or more first locking blocks 13 at intervals, and the assembly 2 is provided with second locking blocks 23 around its periphery. The second locking blocks 23 and the first locking blocks 13 are connected in a one-to-one correspondence to fix the assembly 2 in the control body 1.

[0076] In some embodiments, the second locking block 23 can be engaged with the side of the first locking block 13 facing the bottom of the receiving groove 11, that is, the second locking block 23 is engaged with the inner side of the first locking block 13 to fix the assembly 2 in the control body 1.

[0077] Referring to Figures 9 and 10, in specific implementation, there can be two first locking blocks 13 arranged opposite each other along the above-mentioned set direction, and two second locking blocks 23 are also arranged opposite each other on the periphery of the assembly 2. When the assembly 2 is assembled into the receiving groove 11 in the control body 1, pressing the assembly 2 will deform the first locking block 13 and the second locking block 23 accordingly until the second locking block 23 is engaged with the inner side of the first locking block 13, so that the assembly 2 can be fixedly assembled into the receiving groove 11 in the control body 1.

[0078] Referring to Figure 9, in some embodiments, the sidewall of the receiving groove 11 may be provided with a plurality of first support ribs 14 at intervals, and the assembly 2 is disposed within the space constructed by the plurality of support ribs. The plurality of support ribs can be integrally formed on the sidewall of the receiving groove 11, which can not only strengthen the strength of the receiving groove 11, but also allow the assembly 2 to form multiple contact points with the sidewall of the receiving groove 11, thereby improving the firmness of the assembly 2 in the receiving groove 11 within the control body 1.

[0079] Referring to Figures 9 and 10, in some embodiments, the sidewall of the receiving groove 11 may be provided with a first guide portion 15, and the periphery of the assembly 2 may be provided with a second guide portion 24 to guide the assembly 2 in the receiving groove 11.

[0080] In some embodiments, the second guide portion 24 and the first guide portion 15 may be interlocked to provide guidance for the assembly of the assembly 2 in the receiving groove 11, thereby improving assembly efficiency.

[0081] Referring to Figures 9 and 10, in some embodiments, one of the first guide portion 15 and the second guide portion 24 is a guide protrusion and the other is a guide groove. The guide protrusion is inserted into the guide groove to provide guidance for the assembly of the assembly 2 in the receiving groove 11.

[0082] Referring to Figures 9 and 10, in a specific implementation, a guide protrusion can be provided on the side wall of the receiving groove 11 as a first guide part 15, and a guide groove can be integrally formed on the periphery of the assembly 2 as a second guide part 24. When the guide protrusion is inserted into the guide groove, it can also prevent the assembly 2 from rotating in the receiving groove 11 of the control body 1, further improving the firmness of the assembly 2 in the receiving groove 11 of the control body 1.

[0083] In other embodiments, a guide groove may be provided on the side wall of the receiving groove 11 as a first guide part 15, and a guide protrusion may be integrally formed on the periphery of the assembly 2 as a second guide part 24, which will not be described in detail here.

[0084] Figure 11 shows a structural schematic diagram from another perspective of Figure 6. In conjunction with Figures 6 and 11, in some embodiments, the fastener b may further include a fixing seat 3 and an elastic member 5. The protrusion 4 is connected to the fixing seat 3, and the head of the protrusion 4 protrudes from the surface of the fixing seat 3. The head of the protrusion can be switched in multiple keyways 211, and the bottom of the protrusion 4 is supported by the elastic member 5 to provide tactile feedback when the protrusion 4 is pressed.

[0085] Figure 12 shows a schematic diagram of the assembly structure of the protrusion and elastic element in Figure 6. Referring to Figure 12, in some embodiments, the protrusion 4 can be a keycap with a spherical head that can switch between multiple key slots 211. The keycap's body can be cylindrical and can move up and down within the fixing base 3.

[0086] Figure 13 shows a schematic diagram of the fastener in Figure 6. Referring to Figure 13, in some embodiments, the top of the fixing base 3 may be provided with a mounting groove 31, and the protrusion 4 is disposed in the mounting groove 31. At least a portion of the head of the protrusion 4 extends out of the mounting groove 31 to abut against a keyway 211 of the recess 21. When the control body 1 of the moving member a is pressed, the protrusion 4 can move within the mounting groove 31 and compress the elastic member 5. When the pressing is released, the elastic member 5 resets to drive the protrusion 4 back to the initial position.

[0087] Referring to Figure 13, in some embodiments, the mounting groove 31 may be generally columnar, and the protrusion 4 is gapped within the mounting groove 31 so that it can move within the mounting groove 31.

[0088] Referring to Figures 12 and 13, in some embodiments, the sidewall of the mounting groove 31 is provided with two or more third locking blocks 32 at intervals, and the circumference of the protrusion 4 is provided with a fourth locking block 41. The fourth locking block 41 and the third locking block 32 are connected in a one-to-one correspondence so that the protrusion 4 is connected to the mounting groove 31.

[0089] In some embodiments, the fourth locking block 41 is connected to the side of the third locking block 32 facing away from the moving member a, that is, the fourth locking block 41 is connected to the inner side of the third locking block 32 to restrict the position of the protrusion 4 in the mounting groove 31 so that the protrusion 4 is connected in the mounting groove 31.

[0090] Since the gap of the protrusion 4 is set in the mounting groove 31, the protrusion 4 with the fourth locking block 41 cannot be directly assembled into the mounting groove 31. Therefore, referring to Figure 13, in some embodiments, a notch 33 can be opened on the side wall of the mounting groove 31, and a support seat 34 corresponding to the notch 33 can be provided on the fixing seat 3. The aforementioned third locking block 32 is provided on the inner side wall of the support seat 34. When assembling the protrusion 4, the protrusion 4 is pressed, and the third locking block 32 and the fourth locking block 41 deform accordingly until the fourth locking block 41 is engaged with the inner side of the third locking block 32, so that the assembly 2 can be fixedly assembled into the receiving groove 11 in the control body 1.

[0091] Referring to Figures 12 and 13, in a specific implementation, the sidewall of the mounting groove 31 can be provided with two third locking blocks 32, and the circumference of the protrusion 4 can be provided with two fourth locking blocks 41. The two fourth locking blocks 41 can be symmetrically arranged along the central axis of the protrusion 4, which will not be elaborated here.

[0092] Referring to Figure 13, in some embodiments, the fixing base 3 may include a fixing plate 35 and a first sleeve 36 disposed on the top of the fixing plate 35, the interior of which can be configured as the aforementioned mounting groove 31. Referring to Figure 5, since the first sleeve 36 is disposed on the side of the fixing plate 35 facing the moving member a, a space is reserved between the fixing member b and the moving member a, allowing the sensing member 6 to be assembled between the fixing plate 35 and the moving member a, thereby further reducing the dimension in the height direction of the switching assembly.

[0093] Figure 14 shows a structural schematic diagram of the protrusion in Figure 12 from another perspective. Referring to Figures 12 and 14, in some embodiments, the bottom of the protrusion 4 may be provided with a connecting groove 42, and the sidewalls of the connecting groove 42 are provided with a plurality of second support ribs 43 spaced apart. The elastic member 5 abuts against the plurality of second support ribs 43 to achieve assembly of the elastic member 5 with the protrusion 4.

[0094] Figure 15 shows a structural schematic diagram from another perspective of Figure 13. Referring to Figure 15, in some embodiments, the elastic member 5 can abut against the bottom of the mounting groove 31 to provide support for the elastic member 5 through the bottom of the mounting groove 31. Specifically, a guide post 310 can be provided at the bottom of the mounting groove 31, and the bottom end of the elastic member 5 is fitted onto the guide post 310 to guide the compression deformation of the elastic member 5.

[0095] Figure 16 shows a structural schematic diagram of the fastener in some other embodiments, Figure 17 shows a structural schematic diagram of the fixing seat in Figure 16, and Figure 18 shows a partial structural schematic diagram at point A in Figure 17. Referring to Figures 16-18, in some other embodiments, the sidewall of the mounting groove 31 may be provided with a third limiting portion 37. The entrance of the third limiting portion 37 is located on the opening side of the mounting groove 31, and the third limiting portion 37 extends from the other side of the entrance towards the sidewall of the mounting groove 31. At least a portion of the third limiting portion 37 is inclined in the depth direction of the mounting groove 31.

[0096] Figure 19 shows a schematic diagram of the structure of the protrusion in Figure 16. Referring to Figure 19, a positioning protrusion 44 is provided around the protrusion 4. The positioning protrusion 44 can enter and be positioned within the third limiting part 37 through the inlet of the third limiting part 37. The portion of the third limiting part 37 inclined in the depth direction of the mounting groove 31 can restrict the movement of the positioning protrusion 44 within the third limiting part 37, so as to realize the assembly of the protrusion 4 on the fixed base 3.

[0097] In some embodiments, referring to Figures 16-18, the third limiting part 37 may include an assembly channel and a positioning channel 373, wherein the assembly channel and the positioning channel 373 are connected, and the positioning protrusion 44 enters through the opening at one end of the assembly channel, passes through the assembly channel to reach the other end connected to the positioning channel 373, and enters and is positioned in the positioning channel 373. For example, the assembly channel can be a channel that extends spirally along the circumferential sidewall of the mounting groove 31, or it can be composed of a movable channel 371 and a transfer channel 372. Specifically, the movable channel 371 extends from the opening side of the mounting groove 31 into the interior of the mounting groove 31. The transfer channel 372 is connected to the movable channel 371 and is arranged circumferentially along the mounting groove 31. The bottom of the positioning channel 373 is connected to the transfer channel 372, and the top of the positioning channel 373 extends toward the opening side of the mounting groove 31. The positioning protrusion 44 can enter into the transfer channel 372 through the movable channel 371 and rotate within the transfer channel 372 to enter and be positioned within the positioning channel 373, so as to realize the assembly of the protrusion 4 on the fixed seat 3.

[0098] Referring to Figure 18, in a specific implementation, the active channel 371 can be set along the depth direction of the mounting groove 31 or inclined to the depth direction of the mounting groove 31. The inlet end of the transfer channel 372 is connected to the bottom of 37. The dimension of the transfer channel 372 along the depth direction of the mounting groove 31 needs to be greater than the thickness dimension of the positioning protrusion 44 so that the positioning protrusion 44 can pass through the transfer channel 372 with a gap. The outlet end of the transfer channel 372 can be connected to the bottom of the positioning channel 373. The positioning channel 373 can be set along the depth direction of the mounting groove 31 or inclined to the depth direction of the mounting groove 31. The top of the positioning channel 373 can extend to the bottom of the fixed base 31. The dimension of the positioning channel 373 matches the dimension of the positioning protrusion 44 so that the positioning protrusion 44 is positioned at the bottom of the fixed base 31.

[0099] In other embodiments, the third limiting part 37 may only include the above-mentioned active channel 371 and transfer channel 372. The active channel 371 extends from the opening side of the mounting groove 31 into the interior of the mounting groove 31. The transfer channel 372 is connected to the active channel 371. 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 active channel 371 and be positioned in the transfer channel 372. This can also realize the assembly of the protrusion 4 on the fixed base 3.

[0100] In some embodiments, the third limiting part 37 and the positioning protrusion 44 described above may be arranged in two opposite directions around the central axis of the protrusion 4. Figures 20-22 show a schematic diagram of the assembly of the protrusion shown in Figure 19 on the fixed base. Referring to Figures 20-22, when assembling the protrusion 4 in the mounting groove 31, first align the positioning protrusion 44 on the protrusion with the top of 37, forming the state shown in Figure 20. Then press the protrusion 4, causing the positioning protrusion 44 of the protrusion 4 to move along 37 to the entrance end of the transfer channel, forming the state shown in Figure 21. Rotate the protrusion 4, causing the positioning protrusion 44 of the protrusion 4 to rotate in the transfer channel until it rotates into the positioning channel. Release the press, and under the action of the elastic member 5, the positioning protrusion 44 of the protrusion 4 is positioned at the top of the positioning channel 373, forming the state shown in Figure 22. The protrusion 4 can then be assembled into the mounting groove 31, which is convenient, quick, and improves assembly efficiency.

[0101] It should be noted that the third limiting part 37 and the positioning protrusion 44 mentioned above can also be provided in more quantities, and no limit is imposed here.

[0102] Referring to Figure 18, in some embodiments, the fixing base 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 member a. The interior of the second sleeve 38 can be configured as the aforementioned mounting groove 31. Since the second sleeve 38 is disposed on the side of the fixing plate 35 facing away from the moving member a, the space between the fixing member b and the moving member a is insufficient to assemble the aforementioned sensing element 6. Therefore, the sensing element 6 can be assembled on the side of the fixing plate 35 facing away from the moving member a.

[0103] Referring to Figure 19, in some embodiments, the bottom of the protrusion 4 may be connected to a third guide 45, and a portion of the elastic member 5 is fitted onto the third guide 45 to provide guidance for the deformation recovery of the elastic member 5.

[0104] Referring to Figures 18, 21 and 22, in some embodiments, the bottom of the mounting groove 31 may have a through hole 39, through which the third guide member 45 at the bottom of the protrusion 4 can pass. The elastic member 5 is then disposed between the protrusion 44 and the bottom of the mounting groove 31.

[0105] It should be noted that in other embodiments, the bottom end of the elastic member 5 can extend out of the bottom of the mounting groove 31. The elastic member 5 is supported by a component for mounting the switch assembly. In this case, the control body 1 can have a longer tactile travel to improve the user experience. In specific implementation, the bottom end of the elastic member 5 can simply pass through the through hole 39 at the bottom of the mounting groove 31, which will not be elaborated here.

[0106] The switch assembly shown in this disclosure is functionally consistent with switch assemblies in related technologies, both utilizing the cooperation of the recess 21, the protrusion 4, and the elastic element 5 to achieve positional suspension during movement. The main difference lies in that this disclosure assembles the elastic element 5 and the protrusion 4 onto the fixed member b, and the recess is located on the moving member a, while in related technologies, the elastic element 5 and the protrusion 4 are assembled onto the moving member a, and the recess 21 is located on the fixed member b. While maintaining the same number and spacing of keyways 211, the same size of the protrusion 4, and the same function of the control body 1, the size of the control body 1 in the switch assembly is significantly reduced, resulting in excellent practicality.

[0107] In a second aspect of this disclosure, an electrical device is also provided. FIG23 shows a partial schematic diagram of the electrical device in some embodiments. Referring to FIG23, the electrical device includes a carrier D and the aforementioned switch assembly, wherein a fixing member b of the switch assembly is mounted on the carrier D.

[0108] Electrical equipment having the above-mentioned switch assembly has a travel portion 21 on the side of the moving part a facing the fixed part b. The fixed part b includes a positioning portion 4, which can move in a set direction within the travel portion 21 to limit the travel displacement of the moving part b. This avoids the technical problem in related technologies where the travel portion limiting the travel displacement is set on the fixed part b, which would require the moving part a to cover the decorative travel portion and result in a large size of the moving part a. This reduces the size of the moving part a and the switch assembly to a certain extent, which is conducive to the development of products towards a more refined and compact direction and has good practicality.

[0109] In some embodiments, the carrier D can be the housing of an electrical device, and the fixing member b of the switch assembly can be detachably connected to the carrier D or integrated into the carrier D, without limitation.

[0110] Referring to Figure 23, in some embodiments, a guide groove 7 may be provided on the carrier D, and the moving part a of the switch assembly can slide in the guide groove 7 along a set direction. The width of the guide groove 7 is adapted to the width of the moving part a, and the length of the guide groove 7 must be greater than the length of the moving part a, so that the moving part a can move in the guide groove 7 along the set direction.

[0111] In some embodiments, the electrical device may be a vacuum cleaner or other electrical devices that require multiple functions, such as a hair dryer or a floor scrubber, and there is no limitation herein.
