The present utility model as shown in fig. 1 to 3 provides an electric scooter, which comprises a board surface 1, a connecting seat 2, a connecting assembly 3 and a wheel axle 5, wherein the connecting assembly 3 comprises a center post 31 and an elastic sleeve 32. Specifically, the connection base 2 is disposed on the lower surface of the end of the board 1, the connection base 2 is provided with an orientation hole 21, and the orientation of the orientation hole 21 is obliquely downward in the first direction. The first end of the center post 31 connects the axle 5, and the second end of the center post 31 extends obliquely downward in a second direction, which is opposite to the first direction, where the second end of the center post 31 intersects the orientation hole 21. The elastic sleeve 32 is sleeved at the second end of the middle column 31, and an annular gap is formed on the outer circumferential surface of the middle part of the elastic sleeve 32. The middle part of the wheel axle 5 is provided with a lantern ring 51 and a directional column 52, a positioning ring piece 53 is arranged in the lantern ring 51, and the wheel axle 5 is arranged on the elastic sleeve 32. Specifically, collar 51 is fitted over elastomeric sleeve 32, retaining ring tabs 53 are inserted into the annular gap, and orientation posts 52 extend into orientation holes 21. In this embodiment, an annular gap is provided in the middle of the elastic sleeve 32, that is, the axle 5 is sleeved on the middle of the elastic sleeve 32 by the collar 51, and after the positioning ring piece 53 is embedded in the annular gap, the elastic sleeve 32 can move along the axial direction of the center post 31 and move radially, and is reset under the action of the elastic sleeve 32. In addition, the orientation post 52 extends into the orientation hole 21, and is oriented to be limited by the orientation hole 21, so that the wheel axle 5 can rotate around the orientation post 52, thereby enabling the wheel axle 5 to guide the left steering movement of the skateboard wheel 4. In the present embodiment, the elastic force can be applied to the positioning ring piece 53 from two directions of the axial direction of the center post 31 through the elastic sleeve 32, so that the return performance of the positioning ring piece 53 is more durable, i.e. the wheel axle 5 has a longer performance decay time.
In some further embodiments of the elastic sleeve 32, as shown in fig. 3, the elastic sleeve 32 includes a first elastic sleeve 321 and a second elastic sleeve 322, where the first elastic sleeve 321 and the second elastic sleeve 322 are sleeved on the second end of the central post 31, the first elastic sleeve 321 is located on a side of the second elastic sleeve 322 near the first end of the central post 31, and a gap for the positioning ring piece 53 to extend is reserved between the first elastic sleeve 321 and the second elastic sleeve 322, and the gap is an annular gap. A portion of the collar 51 is sleeved on the first elastic sleeve 321, and another portion of the collar 51 is sleeved on the second elastic sleeve 322. The annular gap is a dividing gap that divides the elastic sleeve 32 into the first elastic sleeve 321 and the second elastic sleeve 322. The elastic sleeve 32 is divided into two parts, so that annular groove-shaped structures on the surface of the sleeve are avoided, and the production and processing difficulty is reduced. More importantly, it can be said that the annular gap is narrowed by adjusting the gap of the first elastic sleeve 321 and the second elastic sleeve 322 so that the first elastic sleeve 321 and the second elastic sleeve 322 maintain the return elastic force to the positioning ring piece 53.
Further, as shown in fig. 3 and 4, the connecting assembly 3 further includes a lock nut 33 and two gaskets 34, and the gaskets 34, the first elastic sleeve 321, the second elastic sleeve 322, the gaskets 34 and the lock nut 33 are sequentially disposed at the second end of the center pillar 31. In this embodiment, a lock nut 33 is disposed at the second end of the center post 31, so that the annular gap can be adjusted at any time by the lock nut 33, or just into the first elastic sleeve 321 and the second elastic sleeve 322, so that the first elastic sleeve 321 and the second elastic sleeve 322 include a force applied to the positioning ring piece 53. In addition, the two gaskets 34 can reduce the use abrasion of the first elastic sleeve 321 and the second elastic sleeve 322, and improve the service life.
For the aforementioned directional hole 21, specifically, the inner diameter of the directional hole 21 gradually increases from the opening to the bottom. The diameter of the orientation post 52 is smaller than the inner diameter of the orientation hole 21 at the opening. In this way, the inner space of the orientation hole 21 is tapered as a whole, so that the orientation column 52 has a larger movable space when the orientation column 52 is extended into the orientation hole 21. The wheel bridge 5 can rotate around the directional column 52 and can swing at will in the conical space, and the opening of the directional hole 21 is a pivot point for swinging the wheel bridge 5.
In addition, the entire orientation column 52 may be in a frustum shape, and the diameter of the orientation column 52 may be smaller as it approaches the end, so that the orientation column 52 may have an inner space for the same movement.
In some embodiments of the wheel axle 5, as shown in fig. 4, a triangular reinforcing portion 54 is provided in the middle of the wheel axle 5, and wheel axles 55 are provided at both ends of the wheel axle 5, and the two wheel axles 55 are provided at both sides of the triangular reinforcing portion 54, that is, at a base angle position. The orientation post 52 is disposed on top of the triangular reinforcement 54. The collar 51 is provided in the triangular reinforcing portion 54, and the orientation column 52 is provided at the apex angle position of the triangular reinforcing portion 54. The triangle reinforcing part 54 is triangular, so that the stability is high, and the whole triangle reinforcing part 54 is thickened, so that the stability of the wheel axle 5 is further improved.
In some embodiments of electric scooter, as shown in fig. 2, the electric scooter further includes a battery compartment 6 and a control box 7, the battery compartment 6 is disposed at the bottom of the board surface 1, the battery compartment 6 is electrically connected with the control box 7, and is provided with a storage and supply electric energy, the control box 7 is disposed on the bottom board of the board surface 1, and the control box 7 is electrically connected with the front wheels or/and the rear wheels.
Further, the electric scooter comprises four scooter wheels 4, wherein the scooter wheels comprise two front wheels and two rear wheels, the two front wheels are rotatably arranged at two ends of one wheel bridge 5, and the two rear wheels are rotatably arranged at two ends of the other wheel bridge 5. In-wheel motors are arranged in the two front wheels or/and in-wheel motors are arranged in the two rear wheels.
In some embodiments of electric scooter, as shown in fig. 2, the electric scooter further includes an upper fixing plate 8, the upper fixing plate 8 is disposed above the end of the plate surface 1, and the upper fixing plate 8 is connected with the connection seat 2. The connecting seat 2 can be stably installed on the plate surface 1 through the connection between the upper fixing plate 8 and the connecting seat 2, and the installation stability of the connecting seat 2 is improved.
In order to improve the steering performance of the electric scooter, in the present embodiment, as shown in fig. 1 and 2, a wing plate 11 for assisting turning is provided at a position near the end of the plate surface 1. The wing plates 11 increase the area of the plate surface 1 near the end, especially the width near the end, for example, when turning is needed, the wing plates 11 can be increased to increase the effect on the wheel bridge 5, increase the turning amplitude, or lock the body adjustment amplitude required for equal turning.
