[0027] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0028] like Figure 1 As shown, a four-way push switch structure according to a preferred embodiment of the present invention includes a first button 1, a second button 2, a rotating shaft 3, a housing 4, a printed circuit board 5 and a bottom cover 6, wherein the housing 4 and the bottom cover 6 are fixedly connected and the printed circuit board 5 is sandwiched therebetween, the second button 2 is mounted on the housing 4 in a liftable manner and presses the printed circuit board 5 in a depressed state, and the first button 1 is rotatably mounted on the housing 4 via the rotating shaft 3 and presses the printed circuit board 5 in a depressed state, thereby connecting or disconnecting the circuit as needed to achieve multi-function control.

[0029] In this embodiment, the first button 1 and the second button 2 are concentrically arranged. In another embodiment, the second button 2 is omitted, and the four-way pressing can be achieved only by the first button 1.

[0030] like Figure 2 As shown, the rotating shaft 3 includes an integrally formed push rod 31 , an elastic structure 32 and a ring 33 , wherein the push rod 31 is connected to the ring 33 via the elastic structure 32 .

[0031] The rotating shaft 3 includes four push rods 31, located below the front, rear, left, and right ends of the first button 1, to control the connection or disconnection of the circuit in four directions. Compared to the existing technology where the push rods and ring are separated, the rotating shaft 3 of the present utility model is integrally formed. This eliminates the need for separate molds for the push rods and ring, reducing mold costs. Furthermore, the push rods and ring do not need to be assembled separately, reducing assembly steps and thus reducing costs.

[0032] The elastic structure 32 includes a first flexible connector 321 and a second flexible connector 322, wherein the first flexible connector 321 is arranged between adjacent top rods 31 to connect the top rods 31, and the second flexible connector 322 connects the first flexible connector 321 and the ring 33. In this embodiment, the elastic structure 32 includes four first flexible connectors 321 and two second flexible connectors 322, and each flexible connector 321, 322 includes at least one W configuration, which connects the four top rods 31 together, ensuring the free up and down movement of the top rods 31 and facilitating assembly. In another embodiment, the elastic structure 32 includes a third flexible connector 323, such as Figure 3 As shown, the number of the third flexible connectors is four, and the four top rods 31 are directly connected to the ring 33. In another embodiment, the third flexible connector 323 of the elastic structure 32 includes at least one S-shaped configuration, such as Figure 4 As shown. It should be understood that the specific elastic weakening arrangement of the elastic structure 32 can be reasonably arranged according to actual conditions. When the elastic structure 32 is integrally formed, in order to ensure smooth glue feeding, the glue inlet 320 is arranged on the ring 33 at the junction of the elastic structure 32 and the ring 33, as shown in FIG. Figure 2-Figure 4 shown.

[0033] See also Figure 2 The ring 33 includes a hole structure 331 and a shaft structure 332, wherein the hole structure 331 is arranged in the radially opposite direction of the ring 33 along the first direction, and the pin 41 of the housing 4 (see Figure 5 ) is inserted into the hole structure 331 to define the first rotation axis 3a, and the shaft structure 332 is arranged in the radial direction opposite to the ring 33 along the second direction perpendicular to the first direction, which is inserted into the hole structure 11 of the first button 1 as a pin (see Figure 6 ) defines a second rotation axis 3b. Thus, the rotation axis 3 comprises a first rotation axis 3a and a second rotation axis 3b that are perpendicular to each other, thereby enabling four-way rotation. It should be understood that the structure of the first rotation axis 3a and the second rotation axis 3b is not limited to this, and the respective rotation axes 3a and 3b may be defined by interchanging the holes and axes or by other structures.

[0034] like Figure 5 As shown, the housing 4 has four first keyway structures 42, and the four push rods 31 are respectively installed on the housing 4 through the corresponding first keyway structures 42 and guided by the first keyway structures 42 to move up and down. Figure 7 In this embodiment, as shown. Figure 5 As shown, the housing 4 further has a second keyway structure 43 located in the center. The second button 2 is mounted on the housing 4 through the second keyway structure 43 and its up and down movement path is guided by the second keyway structure 43 .

[0035] The following briefly describes the working mode of the four-way push switch structure according to the present invention.

[0036] like Figures 8-11 As shown, the four-way pressing shaft 3 rotates along shafts 3a and 3b, driving the first button 1 mounted thereon to move. The first button 1 pushes the push rod 31 downward, triggering microswitches 51 and 52 on the printed circuit board 5 to send signals. When the first button 1 pushes the push rod 31, the elastic structure 32 elastically deforms or stretches, ensuring the downward travel of the push rod 31.

[0037] According to the four-way push switch structure of the present invention, an intelligent switch is provided, which reduces costs by reducing mold costs and the number of parts, improves the parts reuse rate through structural modularization of parts, and shortens the production cycle by optimizing the assembly process.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Various modifications are possible to the above embodiments of the present invention. In other words, any simple, equivalent changes and modifications made in accordance with the claims and description of the present invention fall within the scope of protection of the present invention. Anything not fully described in this invention represents conventional technology.
