DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Such asFigure 1-7 As shown in the figure, a steering column-mounted shift handle includes a handle body 1, a rotor 2, a first rotating shaft 3, a second rotating shaft 4, a PCBA circuit board 5, and a mounting base. One end of the handle body 1 is rotatably connected to the rotor 2 through the first rotating shaft 3. The rotor 2 is rotatably connected to the mounting base through the second rotating shaft 4. The first rotating shaft 3 and the second rotating shaft 4 are perpendicular to each other. A PCBA circuit board 5 is provided below the rotor 2 on the mounting base. A magnetic sensor 6 is provided on the PCBA circuit board 5. A relief opening 7 is provided at the lower end of the rotor 2, and a magnet assembly 8 that cooperates with the magnetic sensor 6 is provided on the relief opening 7.

[0029] In this embodiment, the magnetic sensor 6 is directly provided on the PCBA circuit board 5. When the handle body 1 rotates, it drives the magnet assembly 8 provided on the rotor 2, and the magnetic sensor 6 will sense the change in the magnetic field, and thus directly transmit the signal to the PCBA circuit board 5, and then the PCBA circuit board 5 transmits the signal to the port of the whole vehicle. Among them, the magnetic sensor 6 is a 3D Hall chip, and the setting of the relief opening 7 makes it so that even if the magnet assembly 8 is provided at the lower end of the rotor 2, it will not increase the volume of the rotor 2. The first rotating shaft 3 and the second rotating shaft 4 are perpendicular to each other, so that when the handle body 1 needs to rotate up and down, the handle body 1 rotates around the first rotating shaft 3 relative to the rotor 2 and the mounting base, and when the handle body 1 needs to rotate left and right, the whole formed by the handle body 1 and the rotor 2 rotates around the second rotating shaft 4.

[0030] As a preferred method, the rotor 2 is annular, and the inner and outer cross-sections of the rotor 2 are both rectangular, which is convenient for installing the first rotating shaft 3. The two ends of the first rotating shaft 3 are rotatably connected to the opposite inner side walls on the rotor 2, and the two ends of the first rotating shaft 3 are fixedly connected to one end of the handle body 1. Each of the other two outer side walls on the rotor 2 adjacent to the side wall where the first rotating shaft 3 is provided is provided with a second rotating shaft 4 connected to the mounting base.

[0031] As a preferred method, a bracket 9 is provided at the relief opening 7, and the magnet assembly 8 is installed on the bracket 9. Through the setting of the bracket 9, it is convenient to install the magnet assembly 8 on the bracket 9, and it is also convenient to replace the magnet assembly 8.

[0032] As a preferred method, the indicator light on the handle body 1 is electrically connected to the side of the PCBA circuit board 5 away from the rotor through a wire, and the magnetic sensor 6 is provided on the side of the PCBA circuit board 5 facing the rotor. This design method avoids scratching the wire during the rotation of the handle body 1.

[0033] As a preferred embodiment, the mounting base includes an upper cover 10 and a lower cover 11. The upper cover 10 and the lower cover 11 are locked together by bolts. The upper cover 10 is provided with a first jack 12 that cooperates with one of the second rotating shafts 4 on the rotor 2, and the lower cover 11 is provided with a second jack 13 that cooperates with the other second rotating shaft 4 on the rotor 2. A through hole for connecting the handle body 1 and the rotor 2 is provided on the side wall of the integral formed by combining the upper cover 10 and the lower cover 11. Such a setting method facilitates the installation of the handle body 1, the rotor 2, and the PCBA circuit board 5 in the mounting base.

[0034] As a preferred embodiment, the lower cover 11 includes an upper chamber 14 and a lower chamber 15. The rotor 2 is disposed in the upper chamber 14, and the second jack 13 is disposed on the inner bottom wall of the upper chamber 14. The PCBA circuit board 5 is disposed in the lower chamber 15. The lower cover 11 is provided with a front hole 16 and a rear hole 17 that communicate the upper chamber 14 and the lower chamber 15. The front hole 16 is located directly above the magnetic inductor 6, and the wire passes through the rear hole 17 to electrically connect the indicator light on the handle body 1 and the PCBA circuit board 5. The setting of the front hole 16 is to enable the magnetic inductor 6 to cooperate with the magnet assembly 7, and the setting of the rear hole 17 facilitates the electrical connection of the indicator light on the handle body 1 and the PCBA circuit board 5. At the same time, the method of placing the PCBA circuit board 5 and the rotor 2 separately can prevent the PCBA circuit board 5 from being scratched during the rotation of the rotor 2, and also facilitates assembly.

[0035] As a preferred embodiment, the projection of the bracket 9 in the plane perpendicular to the length line of the handle body 1 is U-shaped. An installation groove 20 is provided on the outer bottom surface of the U-shape of the bracket 9. The magnet assembly 8 is installed in the installation groove 20. The two outer side walls of the U-shape of the bracket 9 are rotatably connected to the inner side wall of the rotor 2. The setting of the bracket 9, on the one hand, facilitates the installation of the magnet assembly 8 on the bracket 9 through the installation groove 20. On the other hand, during the process of the handle body 1 driving the magnet assembly 8 to move, the rotation of the bracket 9 can increase the displacement angle of the magnet assembly 8, expanding the magnetic field change value sensed by the magnetic inductor 6.

[0036] As a preferred embodiment, two sliding grooves 18 are provided on the two inner side walls of the U-shape of the bracket 9. The length line of each sliding groove 18 is perpendicular to both the first rotating shaft 3 and the second rotating shaft 4 at the same time. Both ends of each sliding groove 18 extend outside the bracket 9. One limiting post 19 that cooperates with the sliding groove 18 is provided on each of the two opposite outer side walls of the handle body 1. Through the setting of the sliding groove 18 and the limiting post 19, the relative displacement of the bracket 9 relative to the rotor 2 can be restricted, preventing the bracket 9 from having too large a displacement relative to the rotor 2.
