[0028] The utility model provides Figures 1 to 6 The multi-function button assembly for an intelligent steering wheel shown in the figure comprises: a steering wheel 1, two sets of loading arms 2 are installed on the inner walls at both ends of the steering wheel 1, a mounting shaft 3 is installed between the two sets of loading arms 2, and the upper end faces of the loading arms 2 are provided with integrated board mounting grooves 5, and limiting holes 8 are provided on the side walls at both ends of the integrated board mounting groove 5, an integrated board base 6 is installed just above the integrated board mounting groove 5, and a button integrated board 4 of the same size as the integrated board base 6 is installed above the integrated board base 6; a limiting component, the limiting component is arranged at both ends of the integrated board base 6, and the limiting component is used to fix the integrated board base 6; a switch component, the switch component is arranged in the integrated board base 6, and the switch component is used to remove the integrated board base 6; a rebound component, The component is arranged below the switch component, and the rebound component is used to reset the switch component. Through the structural combination, the loading arms 2 at both ends of the steering wheel, the mounting shaft 3 and the integrated button integrated board 4 system realize the efficient integration and convenient replacement of the control components on the car steering wheel 1. The integrated board base 6 and the button integrated board 4 are firmly connected through the limit component, ensuring the stability and reliability of the operation; at the same time, the introduction of the switch component and the rebound component not only simplifies the disassembly and installation process of the integrated board base 6 and improves the maintenance efficiency, but also ensures the continuous and stable operation of the system through the automatic reset function. This innovative design not only improves the convenience and safety of driving operations, but also significantly enhances the modularity and maintainability of the internal components of the car.

[0029] Furthermore, in this example, Figure 2 and Figure 4As shown, the limiting assembly includes a circular groove 14, which is opened in the middle of both ends of the integrated board base 6, and a limiting cylinder 11 is slidably inserted in the circular groove 14, and the upper and lower edges of the outer end of the limiting cylinder 11 are opened as a bevel, and a connecting piece 13 is installed on the inner end side wall of the limiting cylinder 11, and a connecting rod 12 is installed at the other end of the connecting piece 13. The upper end surface of the integrated board base 6 is provided with a sliding groove 7, and the bottom end of the outer wall of the sliding groove 7 at both ends is slidably installed with a connecting rod 12, and the connecting rod 12 is U-shaped. 3 is installed in the middle position of the end of the connecting rod 12, and a square groove is opened at the middle connection of the two sets of connecting rods 12. The end of the connecting rod 12 in the square groove is L-shaped. When the integrated board base 6 needs to be installed on the integrated board mounting groove 5, first align the integrated board base 6 with the integrated board mounting groove 5 and slowly press down. As the integrated board base 6 approaches, its bottom will contact the outer end inclined surface of the limiting cylinder 11. Due to the inclined surface design, the limiting cylinder 11 will be subjected to an inward extrusion force, forcing it to slide inward along the circular groove 14. During this process, the connecting piece 13 moves with the movement of the limiting cylinder 11, thereby driving the U-shaped connecting rod 12 to slide in the sliding groove 7. When the integrated board base 6 is fully installed in place, the inclined surface of the limiting cylinder 11 is no longer squeezed. At this time, under the action of the rebound component, the limiting cylinder 11 will pop outward, and its inner end is inserted into the limiting hole 8 at both ends of the integrated board installation groove 5. In this way, the integrated board base 6 is firmly limited on the loading arm 2, realizing a firm connection between the two. It is necessary to disassemble the integrated board base 6. When the limit cylinder 11 is pressed inward again, the switch assembly can be used to repeat the above process to make the limit cylinder 11 disengage from the limit hole 8. Then the integrated board base 6 can be easily removed from the loading arm 2. In addition, the square groove connected in the middle of the connecting rod 12 and its L-shaped end design enhance the structural stability between the connecting rods 12, ensuring that the connecting rod 12 can slide smoothly and stably in the sliding groove 7 during the movement of the limit cylinder 11, thereby effectively supporting and guiding the movement of the limit cylinder 11.

[0030] Furthermore, in this example, Figure 3 and Figure 6As shown, the switch assembly includes multiple groups of switch blocks 9, which are installed on the key integrated board 4 at the L-shaped position corresponding to the end of the connecting rod 12, and the key integrated board 4 is provided with a through rectangular slot 24 at the position corresponding to the end of the connecting rod 12, and the switch blocks 9 are installed at both ends of the rectangular slot 24, and a telescopic plate 10 is installed between the two groups of switch blocks 9 on the same side, and a connecting shaft 18 is installed at one end of the bottom of the switch block 9, and a circular hole is provided at the lower end of the connecting shaft 18, and a rotating shaft 19 is rotatably installed in the circular hole, and a mounting seat 20 is rotatably sleeved on the rotating shaft 19, and a vertical guide rod 21 is installed at the bottom of the mounting seat 20, and the vertical guide rod 21 is movably inserted in the guide cylinder 15, and the top of the guide cylinder 15 is provided with a circular groove of the same size as the vertical guide rod 21, and the bottom of the guide cylinder 15 is provided with a circular groove of the same size as the vertical guide rod 21. The end is installed at the upper end of the connecting rod 12, and the vertical guide rod 21 is inserted into a section of the guide cylinder 15 and is sleeved with a vertical spring 23, and a limiting ring 22 is installed at the bottom of the vertical guide rod 21. The top of the vertical spring 23 abuts on the inner wall of the top of the guide cylinder 15, and the bottom of the vertical spring 23 abuts on the side wall of the limiting ring 22 at the bottom of the vertical guide rod 21. First, when the integrated board base 6 is installed on the loading arm 2, the L-shaped structure at the end of the connecting rod 12 will be connected to the switch block 9 installed on the key integrated board 4. At this time, if the integrated board base 6 needs to be disassembled, the user can make the switch block 9 stand up by toggling the switch block 9 from the side, causing the switch block 9 to move. As the switch block 9 stands up, it will drive the connecting shaft 18 at its bottom and the switch block 9 installed on the connecting The rotating shaft 19 on the shaft 18 rotates. Since the rotating shaft 19 is rotatably sleeved on the mounting seat 20, and because the mounting seat 20 is installed at one end position below the switch block 9, when the user manually dials the other end of the switch block 9, the bottom edge of the switch block 9 installed with one end of the mounting seat 20 will contact the key integrated board 4, forming a lever principle, and the user can easily dial the switch block 9 away from one end of the mounting seat 20. When the switch seat 9 is dialed away from one end of the mounting seat 20, the connecting shaft 18 will drive the mounting seat 20 to rise, so the mounting seat 20 will rise accordingly, and then drive the vertical guide rod 21 to slide upward in the guide cylinder 15. During the sliding process, the vertical guide rod 21 will compress the vertical spring 23 sleeved thereon, and the top of the vertical spring 23 will abut against the key integrated board 4. On the top inner wall of the guide cylinder 15, the bottom abuts against the side wall of the limiting ring 22 at the bottom of the vertical guide rod 21. This design ensures the stability and reset ability of the vertical guide rod 21 during movement. When the switch block 9 is operated to be fully erected, the user pinches the switch block 9 with two fingers. At this time, the telescopic plate 10 installed between the two groups of switch blocks 9 on the same side will be squeezed and contracted. At the same time, the switch block 9 will apply an inward force to the limiting cylinder 11 through the L-shaped end of the connecting rod 12, so that the limiting cylinder 11 slides inward along the circular groove 14, thereby escaping from the limiting hole 8. At this time, the integrated board base 6 is no longer limited and can be easily removed from the loading arm 2. After the disassembly operation is completed, if the switch block 9 is released, under the action of the rebound component,The switch assembly is reset, and the elastic force of the vertical spring 23 will reset the vertical guide rod 21 and the mounting seat 20, thereby driving the rotating shaft 19 and the connecting shaft 18 back to the initial position. The switch block 9 is also reset and ready for the next installation operation.

[0031] Furthermore, in this example, Figure 2 and Figure 3 As shown, the rebound assembly includes two groups of horizontal guide rods 16, both of which are mounted on the L-shaped side walls at the end of the connecting rod 12, and a horizontal spring 17 is sleeved on the horizontal guide rod 16, both ends of the horizontal spring 17 abut against the L-shaped side walls at the end of the connecting rod 12. When the integrated board base 6 is disassembled, the user operates the switch assembly to cause the L-shaped structure at the end of the connecting rod 12 to be subjected to an inward force, thereby pushing the limiting cylinder 11 out of the limiting hole 8. During this process, the L-shaped side wall at the end of the connecting rod 12 will compress the horizontal spring 17 sleeved on the horizontal guide rod 16, and the two ends of the horizontal spring 17 abut against the connecting rod 12 respectively. On the two side walls of the L-shape at the end, when the connecting rod 12 is subjected to inward force, the horizontal spring 17 will be compressed and store elastic potential energy. Once the limiting cylinder 11 is completely disengaged from the limiting hole 8, the integrated board base 6 will no longer be limited. At this time, the user can easily remove the integrated board base 6 from the loading arm 2. After the disassembly operation is completed, the inward force is no longer applied to the connecting rod 12, and the elastic potential energy stored in the horizontal spring 17 due to the previous compression will begin to be released. This released force will push the L-shaped end of the connecting rod 12 to move outward, and then the limiting cylinder 11 will also move outward through the transmission mechanism of the switch assembly, preparing for the next installation operation.
