Description

Technical Field

[0001] The present application relates to the field of knobs, and in particular to a knob device and an electrical appliance. Background Art

[0002] Some existing knob devices have a lateral pressing function. For example, the Chinese utility model patent with publication number CN218414377U discloses a sliding multi-functional knob panel. This solution sets the knob assembly to be able to slide laterally relative to the bottom cover, and fixes a button on the bottom cover. The button is triggered by operating the knob assembly to move laterally (front, back, left, and right), thereby realizing the lateral button function. In addition, since the knob assembly of this solution can trigger different buttons when moving in different directions, this makes this solution suitable for scenarios with a variety of control instructions.

[0003] However, in this solution, the knob assembly may move to the left front (or right front, left rear, right rear), causing the buttons on its left and front sides to be triggered, which may lead to disordered execution of button functions. Summary of the invention

[0004] One of the purposes of the present application is to overcome the above-mentioned defects of the prior art and to provide a knob device which is convenient for controlling the lateral button functions.

[0005] The present application provides a knob device comprising a base, a first slide, a knob body, a reset mechanism and at least two buttons, wherein the knob body comprises a stator mechanism and a rotor mechanism rotatably mounted on the stator mechanism, wherein the rotation axis of the rotor mechanism is along a first direction; the stator mechanism, the first slide and the base are connected in sequence, the first slide can only move along a second direction relative to the base, and the stator mechanism can only move along a third direction relative to the first slide, the second direction and the third direction are both perpendicular to the fourth direction, the fourth direction is parallel to the first direction, or the fourth direction is inclined at a preset angle relative to the first direction ; The button and the reset mechanism both act between the stator mechanism and the base. The reset mechanism is used to force the knob body to remain in the initial position through a reset force when the knob device is in a static state, and to force the knob body to return to the initial position through a reset force when the knob body deviates from the initial position; the button is used to be triggered when the knob body moves from the initial position in a direction perpendicular to the fourth direction; a limiting structure is provided between the stator mechanism and the base. Under the limiting action of the limiting structure, when the knob body moves from the initial position in any direction perpendicular to the fourth direction, at most one button is triggered.

[0006] As can be seen from the above, the knob body is configured to be able to slide laterally relative to the base, and a button is arranged between the base and the stator mechanism of the knob body. The button is triggered by operating the knob body to move from an initial position toward a direction perpendicular to the fourth direction, thereby realizing the lateral button function. A limiting structure is further provided between the stator mechanism and the base, so that under the limiting action of the limiting structure, when the knob body moves from the initial position toward any direction perpendicular to the fourth direction, at most one button is triggered, thereby avoiding the situation where multiple buttons are triggered simultaneously.

[0007] In one possible implementation, at least two buttons include a first key and a second key, and the knob body triggers the first key with the shortest stroke when moving from an initial position toward a first vector direction, and triggers the second key with the shortest stroke when moving from an initial position toward a second vector direction, and the knob body cannot trigger the first key and the second key due to the limiting effect of a limiting structure when moving from an initial position toward a third vector direction; the first vector direction, the second vector direction, and the third vector direction are all perpendicular to the fourth direction; the angle between the first vector direction and the second vector direction is less than 180 degrees, and is equal to the sum of the angle between the first vector direction and the third vector direction and the angle between the second vector direction and the third vector direction.

[0008] In a possible implementation, the angle between the fourth direction and the first direction is less than or equal to 60 degrees; or, the angle between the fourth direction and the first direction is less than or equal to 45 degrees; or, the angle between the fourth direction and the first direction is less than or equal to 30 degrees;

[0009] The angle between the first vector direction and the second vector direction is less than or equal to 120 degrees; or, the angle between the first vector direction and the second vector direction is less than or equal to 90 degrees.

[0010] In a possible implementation, the first key, the limiting structure and the second key are distributed in sequence along the circumference of the knob device; the minimum stroke of the knob body moving from the initial position toward the first vector direction to trigger the first key is the first stroke; the minimum stroke of the knob body moving from the initial position toward the second vector direction to trigger the second key is the second stroke; under the limiting action of the limiting structure, the maximum stroke of the knob body moving from the initial position toward the third vector direction is the third stroke; the component of the third stroke in the first vector direction is smaller than the first stroke, and the component of the third stroke in the second vector direction is smaller than the second stroke.

[0011] As can be seen from the above, the first key, the limit structure and the second key are sequentially distributed along the circumference of the knob, and the limit structure limits the stroke, so that when the knob body moves from the initial position to the third vector direction, the component of the maximum stroke in the first vector direction is smaller than the minimum stroke of the knob body moving in the first vector direction to trigger the first key, and the component in the second vector direction is also smaller than the minimum stroke of the knob body moving from the initial position to the second vector direction to trigger the second key. In this way, when the knob body moves in the third vector direction, due to the limit structure's limit on the stroke, the first key and the second key cannot be triggered; it is achieved that when the knob body moves from the initial position to any direction perpendicular to the fourth direction, at most one key is triggered, avoiding the situation of triggering multiple keys.

[0012] In one possible implementation, the limiting structure includes a limiting groove and a limiting protrusion extending into the limiting groove, one of the limiting groove and the limiting protrusion is fixed to the base, and the other is fixed to the stator mechanism; the limiting groove has a middle groove area and at least two radiating groove areas radiating from the middle groove area in a direction perpendicular to the fourth direction, and each radiating groove area corresponds to each button one by one; when the knob body is in the initial position, the limiting protrusion extends from the middle groove area; in the process of the knob body moving from the initial position toward a direction perpendicular to the fourth direction to trigger the button, the limiting protrusion moves from the middle groove area to the corresponding radiating groove area.

[0013] From the above, it can be seen that the limiting structure may include a limiting groove and a limiting protrusion extending into the limiting groove. By setting a limiting groove on one of the base and the stator mechanism and a limiting protrusion on the other, under the cooperation restriction of the limiting groove and the limiting protrusion, the knob body can only move along the extension direction of each radiation slot area to trigger the corresponding button. In this way, the knob body can only move in the extension direction of the radiation slot area, and there is only one button corresponding to the extension direction, and only one button can be triggered. By limiting the movement direction of the knob body, the situation of triggering multiple buttons at the same time can be avoided.

[0014] In a possible implementation, the cross-sectional profile of the normal line of the limiting groove along the fourth direction is in the shape of a cross, and the middle groove area is located at the intersection of the cross; the limiting protrusion is a cylinder with the center line along the fourth direction.

[0015] In a possible implementation, a second slide is further included. The base, the second slide and the stator mechanism are connected in sequence. The second slide is restricted to move only along the third direction relative to the base, and the stator mechanism is restricted to move only along the second direction relative to the second slide.

[0016] In one possible implementation, the first slide has a first slide groove extending along a third direction, the second slide has a second slide groove extending along the second direction, the stator mechanism has a slider extending into the first slide groove and the second slide groove along a fourth direction, the slider has a rectangular cross-sectional profile perpendicular to the fourth direction, a pair of side walls of the slider parallel to the fourth direction slide in slidable engagement with the groove wall of the first slide groove, and another pair of side walls of the slider parallel to the fourth direction slide in slidable engagement with the groove wall of the second slide groove.

[0017] In one possible implementation, the limiting structure includes a limiting groove and a limiting protrusion extending into the limiting groove, one of the limiting groove and the limiting protrusion is fixed to the first slide, and the other is fixed to the second slide; the limiting groove has a middle groove area and at least two radiating groove areas extending radially from the middle groove area in a direction perpendicular to the fourth direction, and each radiating groove area corresponds one by one to each button; when the knob body is in the initial position, the limiting protrusion extends from the middle groove area; in the process of the knob body moving from the initial position to the direction perpendicular to the fourth direction to trigger the button, the limiting protrusion moves from the middle groove area to the corresponding radiating groove area.

[0018] From the above, it can be seen that a second slide can be further provided which is restricted to move only along the third direction relative to the base, and the stator mechanism can be restricted to move only along the second direction relative to the second slide, and a limit groove is provided in one of the first slide and the second slide, and a limit protrusion is provided in the other; the movement direction of the knob body is limited by the cooperation of the limit groove and the limit protrusion, so that the knob body can only move in the extension direction of the radiation slot area to trigger the corresponding button, so that the knob body can trigger at most one button, avoiding the situation of triggering multiple buttons at the same time.

[0019] The second purpose of the present application is to overcome the above-mentioned defects of the prior art and to provide an electrical appliance. The electrical appliance provided by the present application includes a body and the aforementioned knob device, and the knob device is installed on the body through a base.

[0041] The base 1 and the stator mechanism 3 are sequentially connected along the positive direction of the Z axis, and the stator mechanism 3 is limited to be movable along the horizontal plane (XOY plane) relative to the base 1. The rotor mechanism 4 is annular and rotatably sleeved on the outer periphery of the stator mechanism 3, and the rotation axis of the rotor mechanism 4 is along the Z axis direction.

[0042] The stator mechanism 3 and the first slide 2 are sequentially connected to the base 1 along the fourth direction Z. The first slide 2 is restricted to move only along the second direction X relative to the base 1. The stator mechanism 3 is restricted to move only along the third direction Y relative to the first slide 2. Both the second direction X and the third direction Y are perpendicular to the fourth direction Z. This is also conducive to preventing the stator mechanism from rotating relative to the base.

[0043] In other embodiments of the present application, the fourth direction may also be inclined at a preset angle relative to the first direction Z, such as the angle between the fourth direction and the first direction Z is less than or equal to 60 degrees, or the angle between the fourth direction and the first direction Z is less than or equal to 45 degrees, or the angle between the fourth direction and the first direction Z is less than or equal to 30 degrees.

[0045] In other embodiments of the present application, the metal spring sheet 7 may not be provided between the stator mechanism 3 and the base body 1, or other connecting components, such as balls, may be provided between the stator mechanism 3 and the base body 1, which is not limited here.

Optionally, in the embodiment of the present application, there are 4 fixing screws connecting the first slide 2 and the base 1, and in other embodiments, the number of fixing screws may be 3, 5, 6, etc., and in other embodiments, the first slide 2 may be connected to the base 1 by a fixing rod and a first movable guide groove provided on the first slide 2, or the first slide 2 may be connected to the base 1 by a lock and a guide rail extending along the second direction X provided on the first slide 2, so that the first slide 2 is restricted to move only along the second direction X relative to the base 1, or the first slide 2 may be restricted to move only along the second direction X relative to the base 1 by other connection methods. The specific structure is not limited, and those skilled in the art may set it according to actual needs, and it is only necessary to realize that the first slide 2 is restricted to move only along the second direction X relative to the base 1.

[0047] The reset mechanism of this embodiment acts between the stator mechanism and the base body, and can be an elastic structure with one end connected to the stator mechanism and the other end connected to the base body. The reset mechanism is used to force the knob body to remain in the initial position by the reset force when the knob device is in a static state, and to force the knob body to return to the initial position by the reset force when the knob body deviates from the initial position; for example, it can be a coil spring arranged between the radial outer wall surface of the first cylindrical side plate 312 and the radial inner wall surface of the second cylindrical side plate 112, and one end of the coil spring is fixed to the radial outer wall surface of the first cylindrical side plate 312 or the radial inner wall surface of the second cylindrical side plate 112. Optionally, in other embodiments of the present application, the reset mechanism can also be other elastic structures such as spring sheets and rubber bands; or, it can also be magnetic parts respectively fixed to the stator mechanism and the base body, and non-contact reset is achieved by magnetic force. For example: it can be a second magnet and a magnetic attraction part, and the second magnet and the magnetic attraction part One of the components is fixed on the first circular base plate 311, and the other is fixed on the second circular base plate 111. When the knob body is in the initial position, the projections of the second magnet and the magnetic attraction component along the Z-axis direction coincide with each other, and the knob body is forced to return to the initial position when it is maintained in the initial position or deviates from the initial position by the magnetic attraction force of the magnetic attraction component; alternatively, the key and the reset mechanism can be combined to form a reset button, and the reset force of the reset button forces the knob body to remain in the initial position when the knob device is in a static state, and forces the knob body to move to the initial position when the knob body deviates from the initial position. The initial position in the embodiment of the present application is the position where the center line of the knob body coincides with the center line of the base 1, and the reset button is triggered by squeezing when the knob moves along the X0Y plane. When the external force forcing the knob body to move along the X0Y plane is cancelled, the reset force of the reset button forces the knob body to return to the initial position. It can also be other reset mechanisms that can return the knob body, which are not limited here.

[0048] Button 5 is used to trigger the knob body when it moves a preset stroke from the initial position in a direction perpendicular to the fourth direction Z; the reset force of the reset mechanism forces the knob body to remain in the initial position when the knob device is in a static state. When the user operates the knob body to move away from the initial position in any direction parallel to the horizontal plane (XOY plane), the knob body overcomes the reset force of the reset mechanism and moves to trigger the corresponding button. When the external force applied to the knob body is cancelled, the knob body returns to the initial position under the action of the reset force of the reset mechanism.

[0049] In this embodiment, the button 5 is arranged between the stator mechanism 3 and the base 1. Specifically, in this embodiment, the button 5 is installed on the base 1 through the first circuit board. The first circular bottom plate 311 of the base 31 extends from the surface in the positive direction of the Z axis to the positive direction of the Z axis. The triggering portion 315 is used to trigger the corresponding button 5.

[0050] The button 5 includes a first button 51, a second button 52, a third button 53 and a fourth button 54, wherein the first button 51 and the third button 53 are arranged on opposite sides of the rotation axis of the knob body along the X-axis direction, the first button 51 is arranged at the positive end of the X-axis, and the third button 53 is arranged at the negative end of the X-axis; the second button 52 and the fourth button 54 are arranged on opposite sides of the rotation axis of the knob body along the Y-axis direction, the second button 52 is arranged at the positive end of the Y-axis, and the fourth button 54 is arranged at the negative end of the Y-axis. When the user operates the knob body to move along the positive side of the X-axis parallel to the horizontal plane (XOY plane) away from the initial position, the knob body overcomes the reset force of the reset mechanism and moves and triggers the first key 51. When the external force applied to the knob body is cancelled, the knob body returns to the initial position along the negative side of the X-axis under the action of the reset force of the reset mechanism. When the user operates the knob body to move along the positive side of the Y-axis parallel to the horizontal plane (XOY plane) away from the initial position, the knob body overcomes the reset force of the reset mechanism and moves and triggers the second key 52. ​​When the external force applied to the knob body is cancelled, the knob body returns to the initial position along the negative side of the Y-axis under the action of the reset force of the reset mechanism.

[0051] In the embodiment of the present application, the first circular bottom plate 311 of the base 31 extends a trigger portion 315 from the surface in the positive direction of the Z axis to the positive direction of the Z axis. The first slide 2 is provided with a through hole 23 along the Z axis direction, and the through hole 23 is used for the trigger portion 315 to pass through. When the user operates the knob body to overcome the reset force of the reset mechanism and move along the XOY plane for a preset distance, the trigger portion 315 triggers the corresponding button 5.

[0052] In other embodiments of the present application, the structure of the key 5 and the trigger key can be one fixed on the stator mechanism 3 and the other fixed on the base 1, one fixed on the stator mechanism 3 and the other fixed on the first slide 2, or one fixed on the base 1 and the other fixed on the first slide 2. Each key can be installed on the same component or on different components; the structure of each trigger key can be installed on the same component or on different components. For example, the structure of the trigger case is all installed on the base 1, some keys are installed on the stator mechanism 3, and some keys are installed on the first slide 2; or all keys can be installed on the stator mechanism 3, some trigger key structures are installed on the first slide 2, and some trigger key structures are installed on the base. The above is only an example. The technician can set the installation position of the key and the trigger key structure according to the actual design requirements, which is within the protection scope of the present application.

[0053] In the embodiment of the present application, a limiting structure 8 is provided between the stator mechanism 3 and the base body 1. Under the limiting effect of the limiting structure 8, when the knob body moves from the initial position in any direction perpendicular to the fourth direction Z, at most one button 5 is triggered.

[0054] The knob device of this embodiment, when the user pushes the knob body in any direction parallel to the XOY plane, the knob body slides relative to the base along a horizontal plane (XOY plane), and a button is provided between the base and the stator mechanism of the knob body. The corresponding button is triggered by operating the knob body to move in any direction parallel to the XOY plane, thereby realizing the lateral button function. Furthermore, a limiting structure is provided between the stator mechanism and the base, so that under the limiting action of the limiting structure, when the knob body moves from the initial position toward any direction perpendicular to the fourth direction, at most one button is triggered, thereby avoiding the situation where multiple buttons are triggered simultaneously.

[0055] Specifically, taking the positive direction of the X-axis as the first vector direction and the positive direction of the Y-axis as the second vector direction as an example, when the knob body moves from the initial position toward the first vector direction, the first key 51 is triggered with the shortest stroke, and when the knob body moves from the initial position toward the second vector direction, the second key 52 is triggered with the shortest stroke. When the knob body moves from the initial position toward the third vector direction, the first key 51 and the second key 52 cannot be triggered due to the limiting action of the limiting structure 8; the first vector direction, the second vector direction and the third vector direction are all perpendicular to the fourth direction Z.

[0056] It should be noted that the knob body can move in any direction perpendicular to the fourth direction, and can trigger the corresponding button with different strokes. In the embodiment of the present application, the first vector direction is the positive direction of the X-axis, and the second vector direction is the positive direction of the Y-axis. The knob body can move in any direction perpendicular to the fourth direction, wherein moving in the positive direction of the X-axis can trigger the first key 51. If the movement stroke of the knob body allows, the knob body can also trigger the first key 51 by moving in a direction within a range of an angle less than 45 degrees with the positive direction of the X-axis, such as moving in a direction with an angle of 10 degrees, 15 degrees, or 30 degrees with the positive direction of the X-axis. However, the stroke of the knob body moving in different moving directions to trigger the first key 51 is different, wherein the stroke of the knob body moving from the initial position toward the positive direction of the X-axis to triggering the first key 51 is the shortest; similarly, the second key 52 can be triggered by moving the knob body in multiple different vector directions, wherein the stroke of the knob body moving from the initial position toward the positive direction of the Y-axis to triggering the second key 52 is the shortest.

[0057] In this embodiment of the present application, the angle between the first vector direction and the second vector direction is less than 180 degrees, and is equal to the sum of the angle between the first vector direction and the third vector direction and the angle between the second vector direction and the third vector direction. The third vector direction is determined according to the first vector direction, the shortest stroke along the first vector direction to trigger the first key 51, the second vector direction, and the shortest stroke along the second vector direction to trigger the second key 52. ​​For example: when the shortest stroke of the knob body moving from the initial position toward the first vector direction to trigger the first key 51 is equal to the shortest stroke of the knob body moving from the initial position toward the second vector direction to trigger the second key 52, the angle between the first vector direction and the third vector direction and the angle between the second vector direction and the third vector direction are equal, both of which are 45 degrees. When the knob body moves from the initial position toward the third vector direction, the first key 51 and the second key 52 cannot be triggered under the limiting effect of the limiting structure 8.

[0058] In other embodiments of the present application, the angle between the first vector direction and the second vector direction may be less than or equal to 120 degrees; or, the angle between the first vector direction and the second vector direction may be less than or equal to 90 degrees.

[0059] Specifically, the limiting structure 8 may be disposed between the stator mechanism 3 and the base body 1, and the limiting structure 8 is used to limit the movement stroke of the knob body perpendicular to the fourth direction; the limiting structure 8 may be a first limiting member disposed on the stator mechanism 3 or the base body 1, such as a limiting block, a limiting plate, a limiting protrusion, etc.; the limiting structure 8 may also be a first limiting member and a second limiting member, one of the first limiting member and the second limiting member is disposed on the stator mechanism 3, and the other is disposed on the base body 1; for example, the first limiting member may be a limiting plate, and the second limiting structure may be a limiting block; the first limiting member may also be a limiting groove, and the second limiting member may also be a limiting protrusion extending into the limiting groove. It should be noted that the components that trigger at most one button by limiting the movement stroke in the fourth direction are all within the protection scope of this application.

[0060] The above two situations will be described below in conjunction with the structure of the embodiments of the present application:

[0061] Specifically, the limiting structure 8 is used to limit the movement stroke of the knob body along the fourth direction perpendicular to the fourth direction:

[0062] The first key 51, the limiting structure 8 and the second key 52 are distributed in sequence along the circumference of the knob device; the minimum stroke of the knob body moving from the initial position toward the first vector direction to triggering the first key 51 is the first stroke; the minimum stroke of the knob body moving from the initial position toward the second vector direction to triggering the second key 52 is the second stroke; under the limiting action of the limiting structure, the maximum stroke of the knob body moving from the initial position toward the third vector direction is the third stroke; the component of the third stroke in the first vector direction is smaller than the first stroke, and the component of the third stroke in the second vector direction is smaller than the second stroke.

[0063] Similarly, in order to avoid both the second key 52 and the third key 53 being triggered, or to avoid both the third key 53 and the fourth key 54 being triggered, or to avoid both the fourth key 54 and the first key 51 being triggered, the same method as above can be adopted to set a corresponding limiting structure 8 between the stator mechanism 3 or the base 1. The specific setting method is the same as the above-mentioned limiting structure 8, and will not be repeated here.

[0064] In this embodiment, the knob device limits the travel of the knob body from the initial position to the direction perpendicular to the fourth direction, so that only one key can be triggered; the first key, the limit structure and the second key are distributed in sequence along the circumference of the knob; under the limiting effect of the limit structure, the maximum travel of the knob body from the initial position to the third vector direction has a component in the first vector direction that is smaller than the minimum travel of the knob body from the initial position to the first vector direction to trigger the first key, and the component in the second vector direction is smaller than the minimum travel of the knob body from the initial position to the second vector direction to trigger the second key. In this way, when the knob body moves in the third vector direction, due to the limiting effect of the limit structure on the travel, the first key and the second key cannot be triggered, so that when the knob body moves from the initial position to any direction perpendicular to the fourth direction, at most one key is triggered, avoiding the situation of triggering multiple keys at the same time.

[0065] Specifically, the limiting structure 8 can also limit the moving direction of the knob body so as to trigger only one button 5; the specific limiting structure 8 may include a limiting groove and a limiting protrusion extending into the limiting groove, one of the limiting groove and the limiting protrusion is located on the base 1, and the other is located on the stator mechanism 3.

[0066] The limiting structure 8 includes a limiting groove (not shown in the figure) and a limiting protrusion (not shown in the figure) extending from the limiting groove, one of the limiting groove and the limiting protrusion is fixed to the base 1, and the other is fixed to the stator mechanism 3. The limiting groove has a middle groove area and at least two radiating groove areas extending radially from the middle groove area in a direction perpendicular to the fourth direction, and each of the radiating groove areas corresponds to each key one by one; when the knob body is at the initial position, the limiting protrusion extends from the middle groove area; when the knob body moves from the initial position to the direction perpendicular to the fourth direction Z to trigger the key 5, the limiting protrusion moves from the middle groove area to the corresponding radiating groove area.

[0067] In the embodiment of the present application, the buttons include a first button 51, a second button 52, a third button 53 and a fourth button 54, and the buttons are arranged as described above; the middle slot area of ​​the limit slot radiates and extends four radiating slot areas toward the positive side of the X-axis, the negative side of the X-axis, the positive side of the Y-axis and the negative side of the Y-axis, and the cross-sectional profile of the normal of the limit slot along the fourth direction Z is in the shape of a "cross", and the middle slot area is located at the intersection of the "cross"; the limit protrusion is a cylinder with a center line along the fourth direction Z, and in the process of the knob body moving from the initial position to the direction perpendicular to the fourth direction Z to trigger the button, the limit protrusion moves from the middle slot area along the corresponding radiating slot area. In this way, when the user needs to operate the knob body to move along a plane parallel to the horizontal plane (XOY plane), under the mutual cooperation and restriction of the limit groove and the limit protrusion, the user can only operate the knob body to move along the positive side of the X-axis, the negative side of the X-axis, the positive side of the Y-axis or the negative side of the Y-axis and trigger the corresponding button, such as moving along the positive side of the X-axis to trigger the first button 51.

[0068] The limiting structure of the knob device in this embodiment achieves the goal of triggering only one button by limiting the moving direction of the knob body; it includes a limiting groove and a limiting protrusion extending in the limiting groove, and a limiting groove is set on one of the base and the stator mechanism, and a limiting protrusion is set on the other. Under the cooperation and limitation of the limiting groove and the limiting protrusion, the knob body can only move along the extension direction of each radiation slot area to trigger the corresponding button. In this way, the knob body can only move in the extension direction of each radiation slot area, and there is only one button corresponding to the extension direction, and only one button can be triggered. By limiting the moving direction of the knob body, the situation of triggering multiple buttons at the same time can be avoided.

[0069] In the embodiment of the present application, the knob device also includes a second slide 9. The base 1 and the second slide 9 are respectively connected to the stator mechanism 3 in sequence. The second slide 9 is restricted to move only along the third direction Y relative to the base 1, and the stator mechanism 3 is restricted to move only along the second direction X relative to the second slide 9.

[0070] Specifically, the second circular bottom plate 111 of the base 1 has a fourth fixed column extending from the surface in the positive direction of the Z axis to the positive direction of the Z axis, and the second slide 9 is connected to the fourth fixed column by a fixing screw; a second movable guide groove 91 extending along the third direction Y is provided at the connection between the second slide 9 and the base, and the second movable guide groove 91 cooperates with the fixing screw to limit the second slide 9 to move only along the third direction Y relative to the base 1. In the embodiment of the present application, there are 4 fixing screws connecting the second slide 9 to the base 1, and in other embodiments, there may be 3, 5, 6, etc. fixing screws, and in other embodiments, the second slide 9 may be connected to the base 1 by a fixing rod and a second movable guide groove 91 provided on the second slide 9, or by a locking buckle and a guide rail extending along the third direction Y provided on the second slide 9, so that the second slide 9 can be limited to move only along the third direction Y relative to the base 1, or by other connection methods to limit the second slide 9 to move only along the third direction Y relative to the base 1.

[0071] The first slide 2 has a first slide groove 22 extending along the third direction Y, the second slide 9 has a second slide groove 92 extending along the second direction X, the stator mechanism 3 has a slider 314 extending in the first slide groove 22 and the second slide groove 92 along the fourth direction, the slider 314 has a rectangular cross-sectional profile perpendicular to the fourth direction Z, a pair of side walls of the slider 314 slide in cooperation with the groove wall of the first slide groove 22, and another pair of side walls slide in cooperation with the groove wall of the second slide groove 92, a pair of side walls of the slider 314 parallel to the fourth direction Z slide in cooperation with the groove wall of the first slide groove 22, and another pair of side walls of the slider 314 parallel to the fourth direction Z slide in cooperation with the groove wall of the second slide groove 92.

[0072] Specifically, in this embodiment of the present application, the slider 314 is a centerline position of the first circular bottom plate 311 of the base 31 extending from the positive end of the Z-axis toward the Z-axis direction; optionally, in other embodiments of the present application, the slider 314 may also extend from the positive end of the Z-axis toward the Z-axis direction from other positions of the first circular bottom plate 311, and extend into the first slide groove 22 and the second slide groove 92.

[0073] The limiting structure 8 includes a limiting groove 81 and a limiting protrusion 82 extending from the limiting groove 81, one of the limiting groove 81 and the limiting protrusion 82 is fixed to the first slide 2, and the other is fixed to the second slide 9; the limiting groove 81 has a middle groove area 811 and at least two radiating groove areas 812 radiating from the middle groove area in a direction perpendicular to the fourth direction, and each radiating groove area corresponds to each button one by one; when the knob body is in the initial position, the limiting protrusion 82 extends from the middle groove area 811; in the process of the knob body moving from the initial position to the direction perpendicular to the fourth direction Z to trigger the button 5, the limiting protrusion 82 moves from the middle groove area 811 to the corresponding radiating groove area 812.

[0074] Specifically, in the embodiment of the present application, the button 5 includes a first button 51, a second button 52, a third button 53 and a fourth button 54 for illustration, and the button 5 is arranged as described above; the middle slot area 811 of the limiting slot 81 radiates out a first radiating slot area 8121 toward the positive side of the X-axis, radiates out a third radiating slot area 8123 toward the negative side of the X-axis, radiates out a second radiating slot area 8122 toward the positive side of the Y-axis and radiates out a fourth radiating slot area 8124 toward the negative side of the Y-axis, and the cross-sectional profile of the normal of the limiting slot 81 along the fourth direction Z is in the shape of a "cross", and the middle slot area is located at the intersection of the "cross"; the limiting protrusion 82 is a cylinder whose center line is along the fourth direction Z.
