Abstract
The utility model relates to a motor casing structure of an electric bicycle. The motor casing structure comprises a motor casing body having a central shaft, and is characterized in that an opening is arranged on a side face of the motor casing body, and a cover for covering the opening is mounted on the side face of the motor casing by fasteners. The motor casing structure provided by the utility model is advantageous in that the opening can be used dedicated for the maintenance or replacement of Hall elements and carbon brushes, so that the motor casing body is prevented from overall disassembly, and a lot of steps are omitted, thereby reducing the workload, facilitating the maintenance of the motor of the electric bicycle, and providing convenience in use.
Description
Technical field
The utility model belongs to vehicle technology field, particularly relates to a kind of battery case structure of electric bicycle.
Background technology
Electric bicycle is as people's walking-replacing tool, with its Portable energy-saving, environmental protection, the advantage such as convenient and swift and liked by people and be widely used.The motor of electric bicycle is arranged on the wheel of electric bicycle, the motor casing body of electric bicycle is the disc with axis, when motor is brushless electric machine, in motor casing body, Hall element is installed, when motor is brush motor, in motor casing body, there is carbon brush, Hall element or carbon brush in above-mentioned two kinds of motors are the consumable accessory in motor, after Hall element or carbon brush damage, motor need to be unloaded from wheel, take battery case apart and change, keep in repair Hall element or carbon brush, operation is inconvenience very.
Summary of the invention
The utility model provides a kind of simple in structure, battery case structure of being convenient to the electric bicycle of maintenance for solving the technical problem of the electrical machmary maintenance inconvenience existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of motor casing structure of electric bicycle, comprise the motor casing body with axis, it is characterized in that: the side of described motor casing body is provided with opening, the side of described motor casing body is provided with the capping for opening described in capping by securing member.
The utility model can also adopt following technical scheme:
Described opening is rectangle or circle, and described capping is rectangle or the circle corresponding with described opening.
Described opening is the annular opening coaxial with described motor casing body, and described capping is the circular closure coordinating with described opening.
Described securing member is screw.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, the sidepiece at motor casing body is equipped with opening, the corresponding motor casing body interior Hall element in position of this opening or the position of carbon brush, when the Hall element of motor casing body interior or carbon brush impaired after, opening can be used as maintenance or changes the special openings of Hall element, carbon brush, avoid motor casing body to carry out integral demounting, can remove a large amount of operations from, reduce workload, make the motor of electric bicycle be convenient to maintenance, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, motor casing body; 2, securing member; 3, capping.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of motor casing structure of electric bicycle, comprise the motor casing body 1 with axis, motor casing body 1 is generally disc, the parts such as stator, rotor, Hall element or carbon brush are installed in motor casing body 1, when motor is brushless electric machine, Hall element are installed in motor casing body 1, when motor is brush motor, in motor casing body 1, there is carbon brush.The side of motor casing body 1 is provided with opening, and the side of motor casing body 1 is provided with the capping 3 for capping opening by securing member 2.When the consumable accessory Hall element of motor casing body 1 inside or carbon brush impaired after, open the capping 3 at motor casing body 1 one side opening places, people can change or keep in repair Hall element and carbon brush by opening, compare traditional integral dismounting electric bicycle motor shell body 1, this structure can be removed the operation of changing and keeping in repair Hall element or carbon brush from, reduce a large amount of workloads, make motor replacing Hall element or carbon brush more convenient, and can not affect the monnolithic case structure of motor.
Above-mentioned opening is rectangle or circle, and capping 3 is rectangle or the circle corresponding with opening.In addition, opening can be the annular opening coaxial with motor casing body 1, and capping 3 is the circular closure coordinating with opening.In the present embodiment, opening is rectangular aperture, and capping 3 is the rectangle capping corresponding with opening, for connecting capping 3, is screw with the securing member of motor casing body 1.
Above-mentioned execution mode is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model; as a side of motor casing body is provided with detachable end etc. by securing member, within all dropping on protection range of the present utility model.
