Abstract
The utility model discloses an electric tricycle, which comprises a vehicle chassis and three wheels installed on the lower portion of the vehicle chassis, wherein the wheels include two front wheels and a rear wheel. The two front wheels are symmetrically installed on the front portion of the vehicle chassis along the axis in the front-and-back direction of the vehicle chassis, and the rear wheel is installed on the rear portion of the vehicle chassis and located on the axis in the front-and-back direction of the vehicle chassis, and the whole installing positions of the three wheels are in an inverted isosceles triangle. The two front wheels are adopted by the electric tricycle, when the electric tricycle brakes, even if the inertia is large, the conditions including side slip or side overturning do not occur easily due to existence of two balanced fulcrums, and the safety is greatly improved.
Description
Technical field
The utility model relates to a kind of electro-tricycle.
Background technology
Occur a lot of electro-tricycles in the market, be useful on cargo-carrying, be useful on the disabled person, the old man rides instead of walk.Because advantages such as it is simple in structure, pollution-free, safety height are accepted by increasing people now.
Existing electro-tricycle is all according to traditional equilateral triangle layout, and promptly a front-wheel is installed in the under-carriage front portion, and two trailing wheels are installed in the under-carriage rear portion.People always think that such layout safety is better.In fact, when brake or turning, this conventional in layout is breakked away even overturning under action of inertia owing to have only a front-wheel as fulcrum easily, and especially under the wet and slippery situation in ground, sleet sky, this situation is even more serious.
The utility model content
The utility model technical matters to be solved is to overcome the existing potential safety hazard of conventional electric three-wheel vehicle, and a kind of electro-tricycle is provided, and it has the inverted triangle layout, and is more safer than the electro-tricycle of the positive triangle layout of tradition.
The electro-tricycle of the utility model, three wheels that comprise under-carriage and be installed on the under-carriage bottom, said wheel are two front vehicle wheels and a rear wheel; Two front vehicle wheels are installed on the under-carriage front portion to axis symmetrically before and after under-carriage, another rear wheel is installed on the under-carriage rear portion and is positioned at the under-carriage front and back on axis, and the installation site integral body of three wheels is inverted equicrural triangle.
Preferably, the angle of said equicrural triangle drift angle is more than or equal to 30 °, smaller or equal to 60 °.
Further, this electro-tricycle also comprises the shell that is installed on the said under-carriage, and cover top portion is 1.5 meters apart from floor level.
The electro-tricycle of the utility model adopts two front-wheels, when brake, owing to there are two fulcrums of balance, even when inertia is big, also is not prone to and breaks away or the situation of rollover, and safety is greatly improved.
Description of drawings
Fig. 1 is the wheel configuration scheme drawing of conventional electric three-wheel vehicle, and 1 is front vehicle wheel among the figure, and 2-1,2-2 are respectively left back wheel, right rear wheel;
Fig. 2 is the wheel configuration scheme drawing of the electro-tricycle of the utility model, and 3-1,3-2 are respectively front left wheel, right front wheel among the figure, and 4 is rear wheel.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
Conventional electric-powered tricycle wheel layout is as shown in Figure 1, comprises being installed on the anterior front vehicle wheel of under-carriage 1 and the left back wheel 2-1, the right rear wheel 2-2 that are installed on the under-carriage rear portion.When brake in the electric vehicle running or turning, owing to have only 1 one fulcrums of front vehicle wheel, under action of inertia, lack of equilibrium causes battery-driven car to break away even rollover easily.
The electro-tricycle wheel configuration of the utility model is as shown in Figure 2, comprises left and right front vehicle wheel 3-1,3-2 and a rear wheel 4; Left and right front vehicle wheel 3-1,3-2 are installed on the under-carriage front portion to axis symmetrically before and after under-carriage, rear wheel 4 is installed on the under-carriage rear portion and is positioned at the under-carriage front and back on axis, and the installation site integral body of three wheels is inverted equicrural triangle.When brake in the electric vehicle running or turning, the electro-tricycle of the utility model even vehicle inertia is bigger, also be difficult for lack of equilibrium, so safety is better owing to have 3-1, two fulcrums of 3-2.
Find through test, when the angle of three equicrural triangle drift angles that wheel constituted of the utility model electro-tricycle more than or equal to 30 °, during smaller or equal to 60 °, its balance is best.
Further, can also on said under-carriage, shell be installed, further improve safety and traveling comfort; Find after deliberation, when said cover top portion is 1.5 meters (promptly short slightly than normal adult human eye height) apart from ground-surface height, can either satisfy the traveling comfort requirement of taking, can unlikelyly block sight line again and cause potential safety hazard.
Claims (3)
1. electro-tricycle, three wheels that comprise under-carriage and be installed on the under-carriage bottom is characterized in that, said wheel is two front vehicle wheels and a rear wheel; Two front vehicle wheels are installed on the under-carriage front portion to axis symmetrically before and after under-carriage, another rear wheel is installed on the under-carriage rear portion and is positioned at the under-carriage front and back on axis, and the installation site integral body of three wheels is inverted equicrural triangle.
2. electro-tricycle according to claim 1 is characterized in that the angle of said equicrural triangle drift angle is more than or equal to 30 °, smaller or equal to 60 °.
