Abstract
The utility model discloses an electric bicycle's waterproof motor belongs to electric bicycle technical field. Its structure includes the motor, the motor sets up in a casing, be provided with the waterproof cover on the casing, be provided with the transmission tip on the waterproof cover, the side of transmission tip is provided with the sealant fill orifice, the inside sealant storage tank that is provided with of transmission tip, the sealant fill orifice with be provided with the sealant passageway between the sealant storage tank, the sealant passageway is the curve form, the peak of sealant passageway is less than the minimum of sealant storage tank, be provided with the stopper on the sealant fill orifice. The effect of the convenient multifunctional horizontal discharger is beneficial in that. Through setting up bent filiform sealant passageway between sealant fill orifice and sealant storage tank, make the long and thin bending that becomes of sealant storage tank and distance between the sealant fill orifice, set up the buffering position, form buffer distance, avoid moisture entering motor.
Description
Technical field
The utility model relates to electric bicycle technical field, particularly a kind of waterproof machine of electric bicycle.
Background technology
In the process using electric bicycle, run into rain and cross ponding section and be difficult to avoid, this measure can cause motor internal to be intake, and be short-circuited fault, causes motor to quit work or even explodes, making troubles to user.A kind of motor produced on the market at present, that transmission inner end portion on waterproof cover arranges sealant storage tank, transmission end arranged outside sealant fill orifice, in sealant storage tank, pour into sealant by sealant fill orifice, use the method for port lid close encapsulation agent fill orifice, avoid sealant outflow and moisture to enter.This structure has a shortcoming, and the distance between sealant storage tank and sealant fill orifice is short and directly wide, once port lid loosens, moisture enters in gap, owing to almost not having buffer distance, will soon arrive motor internal, meanwhile, sealant also can just be lost from port lid easily.Although this series products is also provided with extending part in port lid inside, stretch in sealant fill orifice, but still do not change this shortcoming.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of waterproof machine of electric bicycle.
Described technical scheme is as follows:
A kind of waterproof machine of electric bicycle, comprise motor, described motor is arranged in a housing, described housing is provided with waterproof cover, described waterproof cover is provided with transmission end, the side of described transmission end is provided with sealant fill orifice, described transmission inner end portion is provided with sealant storage tank, sealant passage is provided with between described sealant fill orifice and described sealant storage tank, the curved shape of described sealant passage, the peak of described sealant passage is lower than the minimum point of sealant storage tank; Described sealant fill orifice is provided with stopper.
Further, the inner surface of described sealant passage near one end of sealant fill orifice is provided with internal thread, and the diameter of described internal thread from inside to outside changes from small to big; The outer surface of described stopper is provided with external screw thread, and described externally threaded diameter from stopper head to stopper tail from large to small.
Further, the outside cover of described stopper has waterproof gasket, and described waterproof gasket is between stopper and sealant fill orifice.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By arranging curvilinear sealant passage between sealant fill orifice and sealant storage tank, the distance between sealant storage tank and sealant fill orifice is made to become elongate curved, be provided with buffer locations, form buffer distance, moisture is avoided to enter motor, meanwhile, sealant also can not be lost from sealant fill orifice easily; And the peak of sealant passage is lower than the minimum point of sealant storage tank, can potential energy difference be produced, moisture is extrapolated, moisture also can be avoided to enter motor.Sealant fill orifice arranges stopper, at the inner surface of sealant passage near one end of sealant fill orifice, the internal thread that diameter from inside to outside changes from small to big is set, at the outer surface of stopper, diameter is set from stopper head to stopper tail external screw thread from large to small, this screw type design, sealant fill orifice and stopper are closely cooperated, prevent from moisture from entering to flow out with sealant, improve the sealing of electric bicycle motor, waterproof effect is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the enlarged diagram of partial structurtes A of the present utility model.
Wherein, 1, motor, 2, housing, 3, waterproof cover, 4, transmission end, 5, sealant fill orifice, 6, sealant storage tank, 7, sealant passage, 8, stopper, 71, internal thread, 81, external screw thread, 82, waterproof gasket.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
Embodiment one
The waterproof machine of a kind of electric bicycle as shown in drawings, comprise motor 1, described motor 1 is arranged in a housing 2, described housing 2 is provided with waterproof cover 3, described waterproof cover 3 is provided with transmission end 4, the side of described transmission end 4 is provided with sealant fill orifice 5, inside, described transmission end 4 is provided with sealant storage tank 6, sealant passage 7 is provided with between described sealant fill orifice 5 and described sealant storage tank 6, the curved shape of described sealant passage 7, the peak of described sealant passage 7 is lower than the minimum point of sealant storage tank 6; Described sealant fill orifice 5 is provided with stopper 8.
The inner surface of described sealant passage 7 near one end of sealant fill orifice 5 is provided with internal thread 71, and the diameter of described internal thread 71 from inside to outside changes from small to big; The outer surface of described stopper 8 is provided with external screw thread 81, and the diameter of described external screw thread 81 from 8, stopper to stopper 8 tail from large to small.
The outside cover of described stopper 8 has waterproof gasket 82, and described waterproof gasket 82 is between stopper 8 and sealant fill orifice 5.
In use, sealant is injected from sealant fill orifice 5, after filling it up with, stopper 8 is screwed.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
