Description

Novel electric vehicle power-assisted riding scheme

Technical Field

This electric motor car helping hand scheme relates to gear and sprocket compound drive system, and the electric bicycle of this scheme of adoption can effectively solve current electric bicycle and ride slow scheduling problem.

Background

The electric vehicle battery technology and the electric vehicle controller technology at the present stage are well developed, the situation of sudden power failure can not occur, and the electric vehicle battery electric quantity can gradually become low until the electric vehicle runs out of power for protecting the battery by force by the controller after the electric vehicle battery electric quantity is extremely low, so that the electric vehicle can not be used for riding.

The power consumption condition of electric motor car battery is directly proportional with the hard condition of electric motor car motor, and the more power saving of laborsaving battery of electric motor car motor, it is rotatory that the personnel of riding can make artifical intervention help motor through trampling the pedal in order to make the more laborsaving electric motor car of motor to the electric motor car motor is more laborsaving, and the more power saving of electric motor car battery, the distance of riding is farther.

Because the electric motor car is heavier, current electric motor car helping hand system of riding in order to obtain under the circumstances that does not have the electricity, and the effect of riding of more laborsaving and more pleasing to the eye appearance design are done very little with the tooth ratio, can be more laborsaving ride under the circumstances that does not have the electricity, nevertheless when the electrified helping hand of needs is ridden, because intervention and the tooth ratio of motor are very little often the effect of riding extremely unobvious.

Disclosure of Invention

According to the problems mentioned above, the invention specifies a riding scheme with more energy and power saving.

The electric motor car of this scheme of adoption can remind the user to make the pedal intervene in order to obtain farther distance of riding as early as possible when the electric quantity is about to be not enough.

The electric motor car battery can not have the electricity suddenly, and the motor rotates the electric energy that consumes hard more, in case the pedal intervenes work, the manual work is stepped on pedal speed under the unchangeable circumstances of assurance speed and is more laborsaving more the motor faster, and the electric quantity uses more slowly. The motor is more strenuous and the electric quantity is used more quickly when the pedal is stepped on by manpower more slowly under the condition of ensuring that the vehicle speed is not changed.

The design that the gear ratio is 1 to 3 is adopted in the existing electric vehicle to rotate the pedal for 1 circle, the chain wheel rotates for 1 circle, and the chain wheel drives the flywheel to rotate for 3 circles through the chain.

The scheme of the invention is as follows: the gear ratio of the power assisting system of the electric vehicle is changed in a limited space, when the electric vehicle adopting the scheme can set the pedal to rotate for one circle as required, the chain wheel can rotate for more than one circle, and the chain wheel drives the flywheel to rotate for more circles through the chain.

The electric motor car of this scheme of adoption all can intervene by the manual work at any time, not only helps the electric motor car to carry out the power saving through trampling the pedal, can also temper the health, will thoroughly solve current electric motor car and step on the pedal in motor work soon yet, also can not the power saving, and the obscure fact with higher speed.

Detailed Description

In order to make the features and advantages of the present invention more comprehensible, the following three examples are provided to better illustrate the present invention in conjunction with the spirit of the present invention. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Case 1

This embodiment is described together with fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5.

In the case, two large chain wheels are respectively arranged in a chain transmission mode; the chain wheel 1 is composed of a chain wheel 2, a small chain wheel 3 and a flywheel 4. Wherein chain wheel 1 is connected with pedal L and pedal R, chain wheel 2 is connected with little chain wheel 3 with one heart, and little chain wheel 3 will drive chain wheel 2 synchronous rotation, chain wheel 1 passes through the chain with little chain wheel 3 and is connected, wherein chain wheel 1 should set up at the homonymy with little chain wheel 3 and be connected in order to make things convenient for the chain, chain wheel 2 should set up at the homonymy with the flywheel 4 and be connected in order to make things convenient for the chain, need be apart from suitable distance under the condition of frame homonymy at chain wheel 2 with chain wheel 3 setting, in order to avoid chain collision each other to produce various problems. The chain collision problem does not need to be considered under the condition that the chain wheel 2 and the chain wheel 3 are arranged on two sides of the frame, and the installation is simple and convenient. The crankset 2 and the small crankset 3 can be arranged in front of the crankset 1, and the effect of the crankset 1 can be unaffected.

The above-mentioned accessories of case 1 can all be the common accessories of the existing electric vehicle or bicycle, and for better explanation, the invention sets the following teeth number:

the teeth of the chain wheel 1 are 32 teeth, the teeth of the chain wheel 2 are 32 teeth, the teeth of the small chain wheel 3 are 16 teeth, and the teeth of the flywheel 4 are 16 teeth.

The chain wheel 1 is a power chain wheel and is connected with the pedal and synchronously rotates, the small chain wheel 3 which is connected with the chain wheel 1 rotates for 2 circles under the condition that the chain wheel 1 rotates for one circle, and the chain wheel 2 which is concentrically connected with the small chain wheel 3 and synchronously rotates also rotates for 2 circles and drives the flywheel 4 to rotate for 4 circles through the chain 5.

Therefore, the wheels of the electric vehicle adopting the connection scheme and the tooth number ratio can rotate for 4 circles under the condition that the pedals rotate for one circle. The tooth ratio is improved by 2 times compared with the electric bicycle without the spirit of the invention.

After the tooth numbers of the chain wheel and the flywheel are changed, a richer rotation ratio can be obtained.

The above case one has pointed out the spirit of the present invention clearly but the structure is large and takes up a large space.
