DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0021] Reference Figure 1-4 As shown: This embodiment provides a rocker structure with a Hall circuit board, including a body 10, an axis 12, a sleeve 11, a magnet 17, and a Hall circuit board 18; the sleeve 11 is covered on the body 10 to form an assembly space; four bosses 14 are arranged on the upper surface of the body 10 around the position of the assembly space, and limiting holes 21 for the bosses 14 to pass through are opened on the four sides of the sleeve 11; when in the assembled state, each boss 14 is arranged through the limiting hole 21 in an interference fit manner; a fourth clearance groove 22 for accommodating the magnet mounting seat 16 is formed at the bottom of the sleeve 11.

[0022] A magnet mounting seat 16 is formed at one end of the shaft 12, and the side of the shaft 12 away from the magnet mounting seat 16 passes through the sleeve 11 coaxially and extends out of the sleeve 11; the magnet mounting seat 16 is coaxially embedded in the fourth clearance groove 22, and the magnet 17 is correspondingly installed on the lower surface of the magnet mounting seat 16. A first clearance groove 23 corresponding to the shape of the magnet 17 is opened at the bottom of the magnet mounting seat 16, and the magnet 17 is fixedly connected to the first clearance groove 23 by adhesive.

[0023] The Hall circuit board 18 is fixedly mounted at the bottom of the inner cavity of the body 10 and is located corresponding to the magnet 17; there is a gap between the Hall circuit board 18 and the magnet 17; the output end of the Hall circuit board 18 is connected to a plurality of pins 19, and each pin 19 extends out of the body 10. A second clearance groove 27 corresponding to the Hall circuit board 18 is formed at the bottom of the inner cavity of the body 10, and the Hall circuit board 18 is correspondingly mounted in the second clearance groove 27.

[0024] The upper surface of the sleeve 11 is formed with a step 13 at a position corresponding to each of the limiting holes 21. By providing the step 13, when in the assembled state, the upper surface height of the boss 14 is equal to or higher than the upper surface of the sleeve 11, ensuring that the structure of the product has a good and regular appearance.

[0025] A positioning block 15 is provided at one side edge of the shaft sleeve 11, and a third clearance groove 20 corresponding to the positioning block 15 is provided on one side of the upper surface of the body 10; when in the assembly state, the positioning block 15 is correspondingly inserted into the third clearance groove 20. By providing the cooperation of the positioning block 15 and the third clearance groove 20, it is convenient to quickly position and install during assembly, and prevent the shaft sleeve 11 and the body 10 from being displaced during assembly, thereby affecting the assembly quality.

[0026] Reference Figure 5 As shown: buckle blocks 24 are arranged on the upper surface of the body 10 near the convex column 14, and through holes 26 for the buckle blocks 24 to penetrate are opened at the positions corresponding to the shaft sleeve 11 and the buckle blocks 24; when in the assembled state, the buckle blocks 24 penetrate the through holes 26 and the part extending outside the through holes 26 forms a bent and clamped section 25. By providing the buckle blocks 24, the bent and clamped section 25 is formed to further clamp the shaft sleeve 11, further improving the stability of the assembly.

[0027] In this embodiment, a structure in which a magnet and a Hall circuit board are coordinated replaces the carbon paint printed structure, thereby ensuring good linear accuracy while improving service life. When in the assembled state, each boss passes through the limiting hole in an interference fit manner, so that the body and the sleeve can be tightly connected and fixed, with good stability, which also directly improves the efficiency of assembly.

[0028] The above embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
