Embodiment 1

[0031] Embodiment 1 (with reference to image 3 , 4 , 5, 6):

[0032] This example is an example of the clutch and its corresponding structure on the basis of the general description. The clutch in this example is a cone-disc friction clutch 7. Among them, the inner cone friction ring 7a (or large circle friction ring) in the cone-disc friction clutch 7 is its static half, and the two inner cone friction rings 7a are fixed together with the left and right support plates 8 (in this example, they are fixed by screws They); the outer cone friction ring 7b (or small circle friction ring) in the cone-disc friction clutch 7 is its moving half, and the two outer cone friction rings 7b pass through the sliding pin 71 parallel to the rotating shaft 6 and its sliding The pin hole is connected with the supporting vertical shaft 3 - the sliding pin 71 is fixed on the limit seat 91 which is fixedly connected with the supporting vertical shaft 3, and the outer cone friction ring 7b has a ...

Embodiment 2

[0035] Embodiment 2 (with reference to Fig. 8, Fig. 9):

[0036] This example is also an example of the clutch and its corresponding structure on the basis of the general description. The clutch in this example is a dog clutch 7'. The moving half of the jaw clutch 7' is a disc-shaped outer ring gear 7b' (or called a small ring gear) with spur teeth, and the static half is a disc that matches the outer ring gear 7b'. Shaped ring gear 7a' (or large ring gear). Wherein, the inner ring gear 7a' is fixedly connected to the supporting vertical shaft 3 through a limit seat 91; The sliding column 71' (due to the obviousness, in Fig. 8 and Fig. 9, only the structure in which the outer ring gear 7b' is fixedly connected with the transition plate 7b1 is drawn); Corresponding sliding post holes in a clearance fit state—the two external ring gears 7b' are connected to the left and right support plates 8 through the sliding post 71' and the sliding post holes. A balance force transmissi...

Embodiment 3

[0039] Embodiment 3 (with reference to Fig. 11, 12, 13, 14):

[0040] This example is an example in which the rotation of the operating handle 51 is optimized on the basis of the general description, embodiment 1 or embodiment 2. In this example, the upper end of the clutch control pipe 4 is fixed with a handle seat 5 for installing its rotating operating handle 51, and the rotating operating handle 51 is mounted on the handle seat 5 in a clamped state by being twisted, and the axis of the hinged shaft 52 is It is separated from the inner wall circle supporting the vertical shaft 3 and cuts to its outer wall circle. On the tube wall supporting the vertical shaft 3, a point where a reference line perpendicular to the axis of the hinged shaft 52 and the axis of the supporting vertical shaft 3 passes through is the point of intersection, and a horizontal T-shaped groove is opened. The longitudinal groove in the recumbent T-shaped groove is a draw-in groove where the rotating ope...

Abstract

A support vertical shaft for a steering operation board of an electric vehicle is vertically connected with the middle part of shaft supported on a left and a right support plates in front of a vehicle frame, and a pair of clutches coaxially sleeved on the shaft are respectively arranged between the vertical shaft and the left support plate and between the vertical shaft and the right support plate. Reset springs acting on the lateral surface of the movable half part and steel balls with an active force opposite to the reset spring are arranged in the clutches, and the steel balls are operated through the operation of clutch operation tubes with corresponding pits. The support vertical shaft is a combined shaft consisting of an upper half vertical shaft sleeved on the lower half vertical shaft, and is fastened by an elastic claw clamping nut mechanism. When the distance between the steering wheel and the driver needs to be adjusted, the clutch operation tube rotates and is separated from the clutches. When the height of the steering wheel is adjusted, the clamping nut is loosened to open the elastic claws. The support vertical shaft is reset after the adjustment. The support vertical shaft has the advantages of convenient adjustment, accurate, stable and reliable result, and better rigidity.

Description

technical field [0001] The invention relates to an electric scooter, in particular to a supporting vertical shaft of a steering operation panel in an electric scooter with differential steering of driving wheels. Background technique [0002] Electric scooter is a kind of means of transportation (or transportation) for one person. Due to its environmental protection, simple structure and easy operation, it is more and more popular among people, especially for the elderly or disabled people. convenience. [0003] In the electric scooter, there is a mechanical transmission steering system that realizes steering through mechanical transmission and finally drives the swing of the steering wheel; there is also an electronically controlled steering system that realizes steering through the speed difference between the left and right driving wheels. For the latter, usually the left and right drive wheels are each equipped with a drive motor. From an operational point of view, the...
