For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In electrical equipment, most devices are provided with knobs to facilitate relatively accurate gear control. However, the existing knob structure is mostly complex, and a large number of components are required, which is not only inconvenient to install, but also poor in stability and poor in screwing feeling, thereby affecting the user experience.

[0037] Based on the problems in the prior art, referring to Figure 1 and Figure 2 The mode switching device 10 provided by the embodiments of the present application is simple in structure, has a small number of components, is convenient and stable to install, and significantly improves the screwing feeling and user experience.

[0038] Further, the mode switching device 10 includes a panel 100, a knob 200, and an elastic member 300.

[0039] The knob 200 is pivotally installed on the panel 100, the knob 200 has multiple modes, the knob 200 is provided with multiple abutting portions 210, and the multiple abutting portions 210 correspond one-to-one to the multiple modes; the elastic member 300 is arranged on the panel 100, and the elastic member 300 is used to abut against any one of the abutting portions 210 to fix and keep the knob 200 in any mode relative to the panel 100.

[0040] In the embodiment, the knob 200 is rotatably arranged on the panel 100, and the knob 200 is arranged to protrude outward from the panel 100, so as to facilitate the user to rotate the knob 200 by hand, thereby realizing switching of the multiple working modes of the dual power transfer switch.

[0041] By arranging the multiple abutting portions 210 on the outer peripheral side wall of the knob 200 on the inner side of the panel 100, any one of the abutting portions 210 can be abutted against by the elastic member 300, thereby realizing the positioning function of the knob 200, so that the knob 200 can be stably kept in the mode corresponding to the abutted abutting portion 210 under the action of the elastic member 300; in addition, during the rotation of the knob 200, the elastic member 300 can also provide damping feeling for the rotation movement of the knob 200 due to the abutting action of the elastic member 300, thereby improving the screwing feeling.

[0042] Therefore, the mode switching device 10 provided by the embodiments of the present application is simple in structure and has a small number of components, which is not only convenient to assemble, but also makes the mode switching device 10 stable and reliable in structure.

[0043] It should be noted that the plurality of "modes" of the knob 200 refer to the states corresponding to the different angles at which the knob 200 is rotated relative to the panel 100; for example, in the present embodiment, the plurality of modes of the knob 200 include an automatic mode, a manual mode, and an isolation mode, and the plurality of abutting portions 210 include a first abutting surface 211 corresponding to the automatic mode, a second abutting surface 212 corresponding to the manual mode, and a third abutting surface 213 corresponding to the isolation mode.

[0044] Therefore, when the knob 200 is in the automatic mode, the elastic member 300 abuts against the first abutting surface 211; if the knob 200 is then rotated counterclockwise by 90°, the elastic member 300 abuts against the second abutting surface 212, and the knob 200 is switched to the manual mode; and if the knob 200 is then rotated clockwise by 90°, the elastic member 300 abuts against the third abutting surface 213, and the knob 200 is switched to the isolation mode.

[0045] It can be understood that the above is only an example and is not the only arrangement; in other embodiments of the present application, other modes can be included, and appropriate adjustments can be made according to different needs of actual products, which are not limited in detail herein.

[0046] In the present embodiment, the first abutting surface 211, the second abutting surface 212, and the third abutting surface 213 are arranged to intersect each other, or the length extension lines of the first abutting surface 211, the second abutting surface 212, and the third abutting surface 213 are arranged to intersect each other, that is, the three abutting surfaces are arranged at an angle, so as to improve the operation feeling when the knob 200 is rotated to switch the state.

[0047] Further, referring to Figure 3 and Figure 4 , the outer peripheral wall of the knob 200 is annularly provided with a matching groove 220, the plurality of abutting portions 210 are arranged at the bottom wall of the matching groove 220, and the elastic member 300 is embedded in the matching groove 220.

[0048] In the present embodiment, the outer peripheral wall of the knob 200 is rotatably arranged in the knob 200 mounting hole of the panel 100, that is, the outer peripheral wall of the knob 200 can be regarded as the rotation shaft of the knob 200, and the bottom wall of the matching groove 220 forms the abutting portion 210; thus, the matching groove 220 is arranged on the portion of the knob 200 located inside the panel 100, and the elastic member 300 is embedded in the matching groove 220, so that the elastic member 300 stably abuts against the abutting portion 210, thereby improving the structural stability.

[0049] Further, please continue to refer to Figure 5The elastic member 300 comprises a contact portion 310 and mounting portions 320 connected to both ends of the contact portion 310, the panel 100 is provided with two mounting posts 110, the two mounting portions 320 are respectively mounted on the two mounting posts 110, the contact portion 310 is in a straight line shape, and the contact portion 310 abuts against the abutting portion 210.

[0050] In the embodiment, the abutting portion 210 is in a planar shape, and thus the straight line-shaped contact portion 310 abuts against the planar abutting portion 210, so as to improve the abutting stability.

[0051] Further, the elastic member 300 further comprises a connecting portion 330, the connecting portion 330 is in an arc shape, the mounting portions 320 and the contact portion 310 are connected through the connecting portion 330, and the mounting portions 320 are pivotally arranged on the mounting posts 110.

[0052] In the embodiment, the two mounting portions 320 are both in a spiral shape, and the two mounting portions 320 are respectively rotatably wound on the mounting posts 110, so as to be movable relative to the panel 100 when the elastic member 300 is pressed.

[0053] In detail, the rotation center of the knob 200 passes through the perpendicular bisector of the line connecting the two mounting posts 110.

[0054] In the embodiment, for example, the two mounting posts 110 are sequentially arranged along the vertical direction, and thus the perpendicular bisector of the line connecting the two mounting posts 110 is a horizontal line; in other words, the rotation center of the knob 200 is located on the horizontal line in the middle of the two mounting posts 110, so that the elastic restoring force of the elastic member 300 on the knob 200 is more balanced, and thus the structural stability of the knob 200 and the elastic member 300 is improved.

[0055] It is worth mentioning that when the elastic member 300 abuts against any abutting portion 210, the abutting surface of the abutting portion 210 is also vertical, so as to realize that the straight line-shaped contact portion 310 completely abuts against the abutting surface.

[0056] Further, please continue to refer to Figure 6 to Figure 8 The mode switching device 10 further comprises a sliding cover plate 400, the sliding cover plate 400 is slidably arranged on the panel 100, the sliding cover plate 400 is in transmission cooperation with the knob 200, the panel 100 is provided with a first operation hole 120, and the sliding cover plate 400 is provided with a second operation hole 410.

[0057] In the embodiment, by screwing the knob 200 to the manual mode, the knob 200 can synchronously drive the sliding cover plate 400 to displace relative to the panel 100, so as to make the first operation hole 120 correspond to the second operation hole 410, thereby facilitating the operation handle to sequentially pass through the first operation hole 120 and the second operation hole 410 for manual operation.

[0058] In detail, the sliding cover plate 400 is provided with a sliding hole 420, and the knob 200 is provided with a drive shaft 230. The drive shaft 230 is slidably engaged with the sliding hole 420 so as to drive the sliding cover plate 400 to move relative to the panel 100 during the rotation of the knob 200.

[0059] In this embodiment, the drive shaft 230 is eccentrically positioned, that is, the drive shaft 230 is offset from the rotation center of the knob 200, and the sliding hole 420 extends vertically. Therefore, during the process of the knob 200 rotating and driving the drive shaft 230 to make a circular motion, the drive shaft 230 will also slide relative to the sliding hole 420 along the extension direction of the sliding hole 420, thereby driving the sliding cover plate 400 to move linearly in the horizontal direction.

[0060] Furthermore, in order to improve the accuracy of the correspondence between the first operation hole 120 and the second operation hole 410 when the knob 200 is switched to manual mode, a first retaining part 130 is also provided on the panel 100, and a second retaining part 430 is provided on the sliding cover plate 400.

[0061] That is, when the first operating hole 120 corresponds to the second operating hole 410, the first holding part 130 and the second holding part 430 engage, thereby achieving the positioning and fixing of the sliding cover plate 400.

[0062] Furthermore, the panel 100 is provided with multiple latches 140 arranged in two rows, with the two rows of latches 140 facing each other. The sliding cover 400 is slidably disposed between the two rows of latches 140 to guide the horizontal displacement of the sliding cover 400. In addition, the multiple latches 140 are also engaged with the surface of the sliding cover 400 to prevent the sliding cover 400 from falling off the panel 100 during sliding, thereby improving the sliding stability.

[0063] In summary, this utility model provides a mode switching device 10. By providing multiple abutment portions 210 on the knob 200, and having an elastic element 300 abut against any one of the abutment portions 210, the knob 200 is positioned, allowing it to stably maintain the mode corresponding to the abutment portion 210 under the action of the elastic element 300. Furthermore, during the turning of the knob 200, the abutment action of the elastic element 300 provides damping for the rotational movement of the knob 200, thereby improving the turning feel. Therefore, the mode switching device 10 provided by this utility model embodiment has a simple structure and few parts, making assembly convenient and ensuring structural stability and reliability.
