[0002] In modern society, adjustment switches are commonly used in car seats. There are many kinds of adjustment switches sold on the market, each with different design concepts, striving to meet the use requirements of different users. However, although these adjustment switches can roughly meet the use requirements, the design is not clever, the structure is complex, there are many components, the volume is large, and it takes up a lot of space. For cars with limited space, it is not conducive to the full utilization of space. In addition, the assembly process is cumbersome, resulting in a long production cycle and high manufacturing costs, which is not conducive to the development of enterprises.

[0003] According to the search, Chinese patent literature, announcement number: CN206961734U, discloses a four-way adjustment switch for the lumbar region of a seat. The utility model has an ingenious structural design, and four arc-shaped concave surfaces are reasonably provided on the control disc, and convex points are provided on the arc-shaped concave surfaces, which effectively improves the accuracy of operation, not only brings convenience to use and facilitates blind operation, but also improves the comfort of use; and the overall structure is simple, compact, and small in size, and the purpose of installation and fixing can be quickly achieved through the installation part. The assembly is simple and quick, which brings convenience to the assembly process, thereby improving production efficiency, shortening the production cycle, reducing production costs, and facilitating wide promotion and application.

[0004] However, the above technology still has some shortcomings. Although the above prior art has four arc-shaped concave surfaces and convex points on the arc-shaped concave surfaces for blind operation and easy assembly, the concave surface of the operation area is easy to hide dirt and is not beautiful. The assembly is too simple and the installation stability is not high, which is easy to be damaged. Utility Model Content

[0028] Specifically, a rectangular mounting piece 11 is fixedly connected to the inner surface of the housing 1, a sheath groove 12 is opened between the rectangular mounting pieces 11, the rectangular mounting piece 11 is set to have the same width as the embedding opening 7, and the four-way switch column 9 is electrically connected to the integrated processor 14. The advantage is that when the four-way button 2 is aligned with the embedding opening 7 and inserted, the touch head 6 and the touch finger 5 will be placed on the top of the four-way switch in accordance with the sheath groove 12. When the adjustment direction button is pressed, the touch finger 5 will press down on the touch head 6, and the touch head 6 will then contact the switch downward, thereby sending instructions to the integrated control circuit board 4 to adjust the seat waist in the specified direction.

[0029] Specifically, a fitting block 13 is fixedly connected to the bottom end of the four-way switch column 9, and there are four groups of fitting blocks 13 arranged in a circular array with the four-way switch column 9 as the center. The advantage is that the grooves left between the rectangular mounting pieces 11 will fit the fitting blocks 13 after installation, so that the four-way button 2 is closely connected with the housing 1 and the four-way switch column 9.

The grabber 17 will fit firmly after the shell 1 and the base plate 3 are inlaid and installed, stabilizing the connectivity of the entire device in the longitudinal direction. Correspondingly, recesses are also reserved on both sides of the middle integrated control circuit board 4 for the grabber 17, so that the device cannot be opened after installation except by external human force, thereby enhancing the safety and service life of the device.
