In addition, the mount can be provided with a power switch, an electric display unit and a light switch. The gear position display H3G has a - rotating member 32, a screwing 34, and a sensing member 36' which causes the 'rotating member 32 to be rotatably disposed in the cymbal P 22 of the mount 20 and has a tooth on its outer periphery. The portion 322 is fitted into the grooves of the operating portion 24 of the mount 420 so that the rotating member can be driven by the fine portion 24 of the seat 2! And the rotation; the knob 34 is connected to the rotation '= and the county_piece 32 side _, and the outer surface of the material is not 342' to indicate that the Anfa block 20 interesting position Zhu area 23, as shown in the third figure The outer circumference method radially protrudes a: ^ for the sensing element 36 to be set, the sensing element 36 is here to magnetize the gear position sensing ϋ 4G in (four) Hall sensing n For example, it is fixed in the fixing portion 22 of the mounting seat 2, and is clamped between the rotating member 32 of the gear position display 30 and the knob 34. The outer surface of the sensor 4 () has a sensing area 42 and a gear display area 23 of the housing 2G, and is magnetically sensed for sensing τ, 36 as shown in the fourth figure. The field rider rotates the operating portion 24 of the mount 2G to perform a shifting operation, for example, the first gear of the third map is switched to the fourth gear of the fifth figure, and the red button 34 of the gear position display is synchronously rotated by the rotating member 32, so that the sense The measuring component 36 senses different positions of the sensing area 42 as the knob 34 rotates, such as the fourth and the ', the figure', the gear position sensor 4 () will feel the change of the magnetic field and The number indicated by her 34 is used to generate a --down signal to the controller's controller to control the motor to output the appropriate boost based on the received gear sensing signal. It can be seen from the above that the position sensor 40 provided by the shift position sensing mechanism 1 of the present invention is installed on the gear position display 30, and the gear position is sensed in response to the action of the gear position. Further, the gear position sensing signal is compared with the I structure, which is not only convenient to install, but also can eliminate unnecessary mounting accessories and effectively reduce the manufacturing cost. In addition, it should be added that the magnetic sensing method is not necessarily used between the sensing element and the gear position sensor, and the light interruption sensing method or the displacement sensing method formed by the combination of the electrode and the brush may be used. Please refer to the seventh figure, which is the shift position sensing mechanism 50 of the second preferred embodiment of the present invention. In the embodiment, the mounting seat 6 has a brewing portion 61 and an operating portion 63, and the fixing portion 61 The gear display area 62 is provided with a ring 68 at the end of the operating portion 63 of the window, and the collar 682 has a cable groove 682. The gear display 64 is coupled to the card slot of the collar by the card portion 642. The inner portion of the 682 can be rotated with the operating portion 63 and has a shifting gear position 65 formed by an Arabic numeral on the outer surface thereof, so that the gear position display material passes through the display portion 62 to display the shooting speed. In addition, the 'sensing element 66 is disposed in the gear position display card w (4) inner groove = the sensor 67 is disposed on the inner surface of the fixing portion 61 of the mounting seat 60, when riding the mounting seat 6G 63 to enter (four) speed operation, sensing element: the gear position sensor 67 will be sensed with the rotation of the gear position display 64 and (4): set the gear position sensor 67 at this time will feel the change of the magnetic field The gear shift position 65 displayed by the 64 is used to generate the sense of position of the slot = the following: = the difference of the shift speed of the third preferred embodiment lies in the "8, (^ Embodiment is substantially the same, but their variations for correction and 82 may be disposed on the mounting base _ winding 80 'floor position sensor 84 provided in the rotary sleeve -82 Thereby,
