Terms used herein in the specification are solely for the purpose of describing specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the related enumerated items.

[0019] An embodiment of the present application provides a multi-directional input device 10, as shown in Figures 1 and 2. The multi-directional input device 10 includes a housing 100, an operating body 200, a rocker assembly 300, a circuit board 400, a return mechanism 500, and an electrical connection member 600. A housing cavity 101 (see Figure 3) is provided inside the housing 100. The housing 100 further has an opening 102 that communicates with the housing cavity 101. At least a portion of the operating body 200 is pivotably mounted inside the housing cavity 101. The operating body 200 has a first end 201 that protrudes outside the housing cavity 101 from the opening 102 and a second end 202 that is inserted into the housing cavity 101. At least a portion of the rocker assembly 300 is located inside the housing 100 and is rotatably mounted inside the housing 100. The operating body 200 is drive-coupled to the rocker assembly 300. The circuit board 400 is installed in the housing cavity 101. The return mechanism 500 is provided in the housing cavity 101 and elastically contacts the second end 202. The return mechanism 500 is configured to return the operating body 200 when at least a portion of the operating body 200 swings within the housing cavity 101. The return mechanism 500 includes a plurality of elastic members 510 and a floating member 520, the floating member 520 is provided with a housing groove 521, and the plurality of elastic members 510 are installed within the housing groove 521. The second end 202 is located on the side of the floating member 520 facing the opening 102. The elastic members 510 elastically contact the second end 202 via the floating member 520 and are configured to return the operating body 200 when at least a portion of the operating body 200 swings within the housing cavity 101. The electrical connection member 600 is installed on the circuit board 400 and electrically connected to the circuit board 400. The rocker assembly 300 is connected to the electrical connection member 600. The electrical connection member 600 is configured to move together with the rocker assembly 300, and the circuit board 400 is configured to detect changes in the position of the electrical connection member 600.

[0020] This invention significantly improves the fatigue resistance of the return mechanism 500 by supporting the floating member 520 with multiple elastic members 510. Even if some of the elastic members 510 experience slight elastic damping due to long-term use, the remaining elastic members 510 can maintain sufficient overall return elasticity, avoiding the drawback that failure of a single elastic member 510 would affect the operation of the multi-directional input device 10. This significantly extends the effective life of the return mechanism 500 and ensures stable elastic support even after long-term use. Furthermore, by adjusting the elastic potential of the elastic members 510, it is possible to achieve changes in the pressing sensation.

[0021] As shown in Figure 2, in some embodiments of the present application, the elastic member 510 is a coil spring and includes a third end 511 and a fourth end 512 arranged opposite each other. The third end 511 is inserted into and abuts against the housing groove 521, while the fourth end 512 is located outside the housing groove 521 and abuts against the housing 100. The abutment of the third end 511 of the elastic member 510 against the housing groove 521 ensures that the mounting position of the elastic member 510 to the floating member 520 is stable and reduces axial displacement during the repeated deformation of the elastic member 510. The fourth end 512 abuts directly against the housing 100 to form a fixed load support point such that the deformation range of the elastic member 510 and the elastic force transmission path always coincide.

[0022] As shown in FIG. 3, in some embodiments of the present application, at least a part of the circuit board 400 is installed within the housing 100 and is located on the side opposite to the opening 102 of the floating member 520. A relief hole 401 is formed in the circuit board 400, and the fourth end 512 penetrates through the relief hole 401 and abuts against the housing 100. By providing the relief hole 401 in the circuit board 400, it is ensured that the fourth end 512 of the elastic member 510 directly abuts against the housing 100, stabilizing the load support point of the elastic member 510 and not affecting the attachment of the circuit board 400 and the realization of its electrical functions. With a simple relief structure, the elastic member 510 can maintain an optimal stress state, facilitate the positioning of the elastic member 510, improve the space utilization rate and reliability of the multi-direction input device 10, and maintain a good operation feeling even after long-term use.

[0023] As shown in FIG. 2, in some embodiments of the present application, the housing 100 includes an upper housing 110 and a lower housing 120 that are fixed to each other. The circuit board 400 is installed in the lower housing 120. A relief groove 121 is provided in the lower housing 120 corresponding to the elastic member 510, and the fourth end 512 abuts against the relief groove 121. By positioning the fourth end 512 of the elastic member 510 through the relief groove 121 provided in the lower housing 120, the elastic member 510 can be quickly and accurately attached, ensuring that the abutting states of the plurality of elastic members 510 are consistent. By fixing the circuit board 400 to the lower housing 120 and making the relief hole 401 (shown in FIG. 3) and the relief groove 121 correspond to each other, the rationality of the layout of components such as the elastic member 510 and the circuit board 400 is further guaranteed, and structural interference caused by assembly errors is avoided. Since the relief groove 121 effectively restricts the position of the fourth end 512 of the elastic member 510, the stability of the elastic force transmission is ensured, the elastic potential attenuation is made uniform after long-term use, and the variation of the operation feeling due to the displacement of a single elastic member 510 is prevented.

[0024] As shown in FIG. 2, in some embodiments of the present application, four elastic members 510 are provided. The four elastic members 510 are distributed around the four sides of the floating member 520. Four accommodation grooves 521 are provided corresponding to the elastic members 510, and the four elastic members 510 are parallel to each other. The design of the symmetric distribution and parallel arrangement of the four elastic members 510 realizes the balance of forces in all directions of the return mechanism 500. The four elastic members 510 are distributed around the four sides of the floating member 520, and the four elastic members 510 are connected one by one to form a substantially square. Thereby, no matter in which direction the operating body 200 swings, it can receive a uniform return elastic force, and the feeling deviation caused by insufficient elastic force in a single direction or uneven force reception is effectively avoided. When the operating body 200 swings in the Y direction, the two elastic members 510 located on both sides close to the driving part 303 of the first rocker 310 deform and return synchronously, so that the feedback of the return force is rapid and gentle, and there is no jamming or delay.

[0025] As shown in FIG. 2, in some embodiments of the present application, on the side of the floating member 520 facing the operating body 200, a first recess 522 is further provided, and the second end 202 abuts against the first recess 522. Here, the first recess 522 is located approximately at the center of the floating member 520, that is, at the intersection where the diagonals of the four elastic members 510 intersect each other. By providing the first recess 522 on the floating member 520, the first recess 522 effectively limits the contact position of the second end 202 of the operating body 200, and prevents relative sliding or displacement from occurring between the floating member 520 and the operating body 200 when the operating body 200 swings, ensuring that the elastic force always acts on the preset force receiving point of the operating body 200 and improving the accuracy of elastic force transmission.

[0026] As shown in Figure 2, in some embodiments of the present application, the rocker assembly 300 includes a first rocker 310 and a second rocker 320 arranged to rotate in two mutually orthogonal directions as the operating body 200 rotates. At least one of the first rocker 310 and the second rocker 320 includes a rocker body 301, rotating parts 302 provided at both ends of the rocker body 301, and a drive unit 303 provided on the rotating parts 302. The drive unit 303 is located within the housing cavity 101, and a second recess 523 is provided on the side of the floating member 520 facing the opening 102, corresponding to the rotating part 302. The fitting of the rotating part 302 of the rocker assembly 300 and the second recess 523 of the floating member 520 provides stable support for the rotational movement of the rocker and ensures smooth rotation of the rocker in a predetermined direction. When the operating body 200 swings, the rotational movement of the rocker assembly 300 and the return movement of the floating member 520 work in coordination, ensuring flexibility of multi-directional input. The limiting action of the second recess 523 prevents misalignment of the rotating part 302, ensuring that the interlocking accuracy does not deteriorate even after long-term use. Because the positioning during assembly is highly accurate, the reliability of the multi-directional input device 10 and the stability of the operating feel are improved.

[0027] As shown in Figure 2, in some embodiments of the present invention, the electrical connection member 600 is provided with an engaging column 601, and the drive unit 303 is provided with an engaging groove 304 corresponding to the engaging column 601, and the engaging groove 304 and the engaging column 601 are fitted together. The electrical connection member 600 is configured to move with the drive unit 303, and the circuit board 400 is configured to detect the movement of the electrical connection member 600. The fitting structure between the engaging column 601 and the engaging groove 304 ensures the synchronization of their operation, thereby guaranteeing the accuracy of the circuit board 400's detection of positional changes of the electrical connection member 600, and improving the accuracy of the input signal of the multi-directional input device 10.

[0028] As shown in Figure 4, an embodiment of the present invention further provides a control handle 30 equipped with the aforementioned multi-directional input device 10.

[0029] As shown in Figure 5, the embodiment of the present invention further provides an operating device 40 equipped with the aforementioned control handle 30.

[0030] The embodiments described above are for illustrative purposes only and are not limiting. Although the present application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that it is possible to modify or substitute equivalents the technical solutions of the present application without departing from the technical idea and scope of the present application.
