The main knob assembly is connected to the steering assembly, and the menu assembly and sub-knob assembly both act on the main PCB board 3.

[0019] A main knob mounting hole is provided on the top of the key box cover. The steering assembly includes a steering bracket 6, a spring 9, an x-axis steering bracket 7, a y-axis steering bracket 8 and a large round button encoder PCBA assembly 10. The steering bracket 6 is fixed to the key box cover 11 by a screw 1. The x-axis steering bracket 7 and the y-axis steering bracket 8 are both arranged in the steering bracket 6. A column is provided at the bottom of the steering bracket 6. The x-axis steering bracket 7 is arranged at the bottom of the steering bracket 6 and surrounds the column. The y-axis steering bracket 8 is arranged above the x-axis steering bracket 7 and is clamped to the x-axis steering bracket 7. The large round button encoder PCBA assembly 10 is provided at the main knob mounting hole and fixed to the y-axis steering bracket 8 by screw 1. One end of the spring 9 is sleeved on the column, and the other end of the spring 9 passes through the x-axis steering and is clamped into the hole at the bottom of the y-axis steering bracket 8. The main knob assembly is provided at the main knob mounting hole and connected to the large round button encoder PCBA assembly 10. The main PCB board 3 is provided with four steering buttons distributed in a cross shape, and the steering bracket 6 is provided with four top members 5 corresponding to the steering buttons one by one. The two ends of the top members 5 are respectively in contact with the y-axis steering bracket 8 and the corresponding steering buttons.

[0020] By swinging the y-axis steering bracket 8, the y-axis steering bracket 8 presses down different top parts 5, and then the top parts 5 press down the corresponding steering buttons, thereby realizing the steering functions in the four directions of up, down, left and right. During the steering operation, the large round button encoder PCBA assembly 10 and the spring 9 swing with the y-axis steering bracket 8. After releasing the y-axis steering bracket 8, the spring 9 automatically returns to its position, thereby driving the large round button encoder PCBA assembly 10 and the y-axis steering bracket 8 to return to the original position.

[0021] The main knob assembly includes a large round plastic knob 18, a large round decorative ring 19, a large round button cover bracket 20 and a large round button cover 21. The large round plastic knob 18 is arranged on the top of the button box cover 11 at the main knob mounting hole. The large round button encoder PCBA assembly includes a PCBA and a large round button encoder and a confirmation button installed on the PCBA. The large round plastic knob 18 is sleeved on the large round button encoder and clamped with the outer wall of the large round button encoder. The large round decorative ring 19 is embedded in the top of the large round plastic knob 18. The large round button cover 21 bracket is arranged on the large round decorative ring 19. The large round button cover 21 is arranged on the large round button cover bracket 20. A bracket guide rail is integrally formed at the bottom of the large round button cover bracket 20. The bracket guide rail passes downward through the large round decorative ring 19, the large round plastic knob 18, the large round button encoder in sequence and abuts against the confirmation button. The bracket guide rail is slidably connected to the inner wall of the large round button encoder and can slide up and down.

[0022] By rotating the large round plastic knob 18, the large round button encoder is driven to rotate, thereby realizing a 360-degree rotation function, which can be used to adjust parameters such as volume; by pressing down the large round button cover 21, the large round button cover 21 bracket 20 presses down the confirmation button, thereby realizing functions such as press down confirmation.

[0023] The menu component includes a HOME button 15, an SRC button 14 and a BACK button 13. A key slot is provided on the key box cover 11. The HOME button 15, the SRC button 14 and the BACK button 13 are all arranged in the key slot. The key slot is provided with sockets corresponding to the HOME button 15, the SRC button 14 and the BACK button 13 one by one. The bottom of the HOME button 15, the SRC button 14 and the BACK button 13 are all provided with key guides that are plugged into the corresponding sockets and act on the main PCB board 3. The key guides are slidably connected to the inner walls of the corresponding sockets and can slide up and down.

[0024] Main PCB 3 is equipped with menu buttons corresponding to HOME button 15, SRC button 14, and BACK button 13. The button guides abut the corresponding menu buttons. Pressing HOME button 15, SRC button 14, or BACK button 13 causes the HOME button 15, SRC button 14, or BACK button 13 to press the corresponding menu button, thereby enabling functions such as main menu selection, audio source selection, and backtracking.

[0025] A sub-knob mounting hole is defined at the top of the keybox cover 11. The sub-knob assembly comprises a small round plastic knob 12, a small round decorative ring 16, and a small round knob cover 17. A small round knob encoder 4 is mounted on the main PCB. The small round plastic knob 12 is positioned in the sub-knob mounting hole and engages with the small round knob encoder 4. The small round decorative ring 16 engages the top of the small round plastic knob 12, and the small round knob cover 17 is positioned above the small round decorative ring 16. Rotating the small round plastic knob 12 drives the small round knob encoder, allowing for additional parameter adjustments as needed.

[0026] Based on the above components, the assembly process of the multi-function knob switch of the present invention is as follows:

[0027] The first step is to assemble the steering assembly, main knob assembly, and sub-knob assembly according to the component classification, then invert the key box cover 11 and place the steering assembly inside the key box cover 11, use screw 1 to fix the steering bracket 6 on the key box cover 11, complete the installation of the steering assembly, and at the same time place each button in the menu assembly in the button slot of the key box cover 11; the second step is to place the top piece 5 in the corresponding position of the steering bracket 6, and place the main PCB board 3 under the steering assembly, and then use screw 1 to fix the main PCB board 3 on the key box cover 11, so that the steering button on the PCB board is against the top piece 5. Then, the menu button is abutted against the corresponding button guide to complete the installation of the PCB board; the third step is to put the button box upper cover 11 upright, then put the large round plastic knob 18 on the large round button encoder and snap it together with the large round button encoder, so that the bracket guide at the bottom of the large round button cover bracket 20 is slidably connected with the large round button encoder and abutted against the confirmation button, and at the same time, the small round plastic knob 12 is snapped together with the small round button encoder 4 to complete the installation of the main knob assembly and the sub-knob assembly; finally, buckle the button box lower cover 2 with the button box upper cover 11, and fix the button box lower cover 2 and the button box upper cover 11 together with the screw 1 to complete the assembly of the entire product.

[0028] Based on the above structure and assembly process, the present invention realizes the four directional functions of up, down, left, and right, as well as the rotation adjustment function and the press-down confirmation function by setting the steering component and the knob component, combining the main PCB board 3 and the large round button encoder PCBA component 10. That is, the relevant functions are integrated in the form of components, and then the components can be modularly produced in the form of components during the manufacturing process, and then assembled in the order of the components. This can not only simplify the structure, facilitate assembly and subsequent maintenance, but also reduce manufacturing costs.

[0029] Finally, although the above description has shown and described the embodiments of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
