CONCRETE EMBODIMENT

[0033] The input device 100 of the utility model will be described below in conjunction with Figures 1 to 9

[0034] Please refer to Figures 1 to 4 ​As shown, the input device 100 includes a housing 1 having an upper shell 11 of metal material and an insulating lower shell 12 assembled with the upper shell 11. The upper shell 11 includes an upper wall portion 111 having an opening portion, four side wall portions 112 extending downward from the periphery of the upper wall portion 111, and the lower shell 12 is fixed to the lower end of the upper shell 11 to form a bottom wall portion. The upper wall portion 111 and the side wall portions 112 of the upper shell 11 and the lower shell 12 form a receiving space 113 therebetween. The input device 100 further includes an operation member 2 inserted into the receiving space 113 through the opening portion and capable of performing a tilting operation, a first actuating element 3 provided in the receiving space 113 and linked with the operation member 2, the first actuating element 3 being rotated as the operation member 2 is tilted in a first direction, a first motion detecting member 4 for detecting the rotation of the first actuating element 3, a second actuating element 5 provided in the receiving space 113, the second actuating element 5 being located below the first actuating element 3 and orthogonal to the first actuating element 3, a second motion detecting member 6 for detecting the rotation of the second actuating element 5, and a restoring mechanism 7 for restoring the first actuating element 3 and the second actuating element 5 to an initial state by means of the operation member 2. The first motion detecting member and the second motion detecting member are used to detect the rotation of the first actuating element and the second actuating element. In other embodiments, the first actuating element and the second actuating element can also move translationally along the bottom wall portion, in which case the first motion detecting member and the second motion detecting member are used to detect the translational movement of the first actuating element and the second actuating element.

[0035] The first actuating element 3 is linked with the operation member 2 and is rotated as the operation member 2 is tilted in a first direction. The first actuating element 3 is provided with a first through hole 31 for insertion of the operation member 2, and has a first shaft portion 32 and a second shaft portion 33 located respectively on the two sides of the first through hole 31 in a second direction perpendicular to the first direction. The lower shell 12 is provided with a base 121 for supporting the first shaft portion 32 and the second shaft portion 33.

[0036] In particular, reference is made to Figures 5 to 8As shown, the operation member 2 comprises a control lever 21 capable of performing the pouring operation, a cylindrical peripheral wall 23 formed downwardly from the lower surface of the control lever 21, and an opening 22 formed upwardly from the lower surface of the control lever 21. The restoring mechanism 7 comprises a driving rod 71 installed in the opening 22 and a return spring 72 sleeved outside the driving rod 71. The driving rod 71 comprises a base 711 received by the lower shell 12, a boss 712 formed upwardly from the base 711, and a mounting portion 713 formed further upwardly from the boss 712, the mounting portion 713 being installed in the opening 22. The boss 712 has a cross-sectional area in the radial direction larger than that of the mounting portion 713, so as to improve the strength of the root of the driving rod 71. The restoring mechanism 7 is arranged below the operation member 2, and elastically supports the operation member 2. The lower shell 12 is formed with a convex 122 corresponding to the position of the driving rod 71. When the operation member 2 is subjected to an external force to perform the pouring operation, the driving rod 71 is deflected, and the return spring 72 is further compressed under the influence of the inclined surface in the convex 122. When the external force applied to the operation member 2 is removed, the driving rod 71 is guided by the inclined surface of the convex 122 under the action of the return spring 72, and returns to the initial position. The restoring mechanism 7 restores the first actuating element 3 and the second actuating element 5 to the initial state by means of the operation member 2.

[0037] Further combining Figure 9As shown, the lower surface of the control rod 21 and the upper surface of the boss 712 are oppositely arranged, both of which are planes extending in the horizontal direction. An axial floating gap is formed between the upper surface of the boss 712 and the lower surface of the control rod 21. The radial dimension of the boss 712 is smaller than the cylindrical peripheral wall 23 to ensure the maximum floating space of the control rod 21. And compared with the lower end edge of the cylindrical peripheral wall 23, the upper surface of the boss 712 is closer to the lower surface of the control rod 21, that is, the upper surface of the boss 712 is above the lower end edge of the cylindrical peripheral wall 23 in the up-down direction. The cylindrical peripheral wall 23 is downwardly open and can partially cover the outer surface of the boss 712. The inner surface of the cylindrical peripheral wall 23, the lower surface of the control rod 21 and the outer surface of the boss 712 and the mounting portion 713 together form a receiving cavity for accommodating the return spring 72. An annular groove 714 is arranged at the connection between the base 711 and the boss 712. The return spring 72 is a coil spring directly sleeved on the outer surface of the boss 712, one end of which abuts against the lower surface of the control rod 21 and the other end of which is arranged in the annular groove 714. Since the upper surface of the boss 712 is above the lower end edge of the cylindrical peripheral wall 23 in the up-down direction, the return spring 72 can be radially limited by one of the boss 712 and the cylindrical peripheral wall 23 at each position in the up-down direction. Under the limitation of the boss 712 and the cylindrical peripheral wall 23, the return spring 72 can be elastically deformed along the drive rod 71 stably.

[0038] In addition, the mounting portion 713 is concavely arranged with a plurality of mounting grooves 715 extending in the up-down direction, and the opening 22 is inwardly protruding to form a plurality of long strip-shaped protruding ribs. The mounting portion 713 extends into the opening 22, and the protruding ribs are engaged with the mounting grooves 715 to limit the relative rotation of the control rod 21 and the mounting portion 713 in the circumferential direction.

[0039] The above only describes some embodiments of the present application, not all embodiments, and any equivalent changes made by those skilled in the art by reading the description of the present application are covered by the claims of the present application.
