Abstract

The utility model relates to an electric bicycle which comprises a bicycle frame, a front wheel, a rear wheel, a motor, a battery and a controller, wherein the controller is independently arranged at the upper part of a front beam of the bicycle frame and the controller is positioned in the waterproof included angle of a fender of the front wheel. The controller of the utility model is independently installed on the upper part of the beam, and thus, the utility model is convenient to install and maintain; the controller is positioned in the waterproof included angle a of the fender of the front wheel, so the rain water splashed by the front wheel can not splash onto the controller when a rider rides the electric bicycle in a rainy day. Because the controller is positioned on the upper part of the front beam and has a long distance from the ground, the electric bicycle can not be submerged in the water when the electric bicycle passes through a road surface with accumulated water. Thus, the failure rate of the controller is reduced and the service life is prolonged; the problem that the controller is wetted in rainy and snowy days when the electric bicycle passes though the road surface with accumulated water is solved, and as a result, the quality of the electric bicycle is improved.

Description

Electrical Bicycle

Technical field

The utility model relates to a kind of Electrical Bicycle.

Background technology

Electrical Bicycle is that motor, battery, controller and speed control crank are housed on the basis of bicycle, battery provides power, be connected with controller, motor, speed control crank and brake lever respectively by lead, Electrical Bicycle had electronicly ride and ride two functions of travelling.Because controller is the control center of Electrical Bicycle, so the functional reliability of controller directly influences the in-use performance of Electrical Bicycle.At present, controller on the Electrical Bicycle mostly is installed in the bottom of stretcher and puts together with drive disk assembly, block with cover panel again, because of controller and other parts load in mixture, the outlet of controller is connected with battery, motor, speed control crank and brake lever respectively again, so mainly there is two large problems in present controller: 1, install, safeguard inconvenience.Because controller is installed with other parts, installing space is little, so controller very inconvenience in installing and keeping in repair.2, the problem of paddling of sleety weather.Though the controller of Electrical Bicycle is to be placed in the cover panel, parts such as a cover panel chain wheel to the vehicle frame bottom, chain are covered and are played decoration, beauty function, are difficult to play waterproof action.The Electrical Bicycle that also has is the bottom that controller is placed on battery case, but all be positioned at the bottom of vehicle frame, during vehicle is exercised, especially front-wheel can get rid of the ponding on the road and splash the vehicle frame bottom, and when by the serious road surface of ponding, be immersed in the water because of the position of controller is lower, very easily cause controller to lose efficacy.The defective of said structure has caused present controller failure rate high, has a strong impact on the quality of Electrical Bicycle.

Summary of the invention

The purpose of this utility model provides a kind of installation, easy to maintenance, can reduce the Electrical Bicycle of controller failure rate.

The utility model is that the technical scheme that achieves the above object is: a kind of Electrical Bicycle comprises vehicle frame, front-wheel, trailing wheel, motor, battery and controller, described controller independently is installed in the top of the front beam of frame, and controller is positioned at the anti-angle a that dabbles of front-wheel mud plate.

The utility model compared with prior art has the following advantages: 1, be convenient to installation and maintenance.Because controller is independent placement, has the sufficient mounting space, is convenient to the installation and maintenance of controller.2, water resistance is good.Controller of the present utility model is positioned at the waterproof angle a of front-wheel mud plate, so ride at sleety weather, front-wheel gets rid of and spatters that rainwater all can not be thrown on the controller and improve water resistance.3, solved the controller problem of paddling.The controller of the utility model Electrical Bicycle is installed in the top of front-axle beam, apart from the ground height, vehicle can not be immersed in the water during by the ponding road surface, reduced the fault rate of controller effectively, improved service life, solved the paddle problem of controller, thereby improved the quality of Electrical Bicycle in the sleet sky.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is further described in detail.

Fig. 1 is a structural representation of the present utility model.

Wherein: the 1-front-wheel; The 2-speed control crank; The 3-lead; 4-front-wheel mud plate; The 5-controller; The 6-vehicle frame; The 6-1-front-axle beam; The 7-chain drive; The 8-crank; The 9-battery; The 10-motor, the 11-trailing wheel.

The specific embodiment

See Fig. 1 Electrical Bicycle of the present utility model, comprise vehicle frame 6, front-wheel 1, trailing wheel 11 and motor 10, battery 9 and controller 5, the back vent of vehicle frame 6 is connected with trailing wheel 11 by rear axle, its front fork is connected with front-wheel 1 by front axle, vehicle frame 6 bottoms are welded with center tap, axis is installed in the center tap context, axis, sprocket wheel on messenger chain and the rear axle constitutes chain drive 7, and by motor 10 drivings that are contained on the rear axle, crank 8 is housed on the axis, the battery 9 that is contained in 6 pipes of vehicle frame rear portion provides power supply for motor 10, this controller 5 independently is installed in the front-axle beam 6-1 top of vehicle frame 6, and by lead 3 respectively with motor 10, speed control crank 2 and brake lever are connected, controller 5 is positioned at the waterproof angle a of front-wheel mud plate 4, front-wheel 1 can not got rid of rainwater in travelling to be spattered on the controller 5, the preferably tilting front-axle beam 6-1 top of this controller 5 at vehicle frame 6, and controller 5 has the leak free box body, this box body for former and later two housings or about two housings connect and compose, its box body can be geometric configuratioies such as circle or ellipse, the outlet of controller 5 passes from lower part of frame by sealing shroud, and can not cause controller 5 to make moist and damage.

Claims

1, a kind of Electrical Bicycle, comprise vehicle frame (6), front-wheel (1), trailing wheel (11) and motor (10), battery (9) and controller (5), it is characterized by: described controller (5) independently is installed in front-axle beam (6-1) top of vehicle frame (6), and controller (5) is positioned at the waterproof angle a of front-wheel mud plate (4).
