Abstract

The utility model discloses an electric vehicle electric machine end cover, including the end cover body, the end cover body is the discoid structure of indent, discoid structure bottom has the annular platform of evagination, the dish mouth circumference of the disc of end cover body is extended to form and is had a few word limits that are " nearly " word structure, a few word edges are evenly opened there is circular installation through -hole. The utility model discloses processing technology is simple, and low in production cost and intensity are highly dense to be sealed, and the quality is reliable.

Description

Electric bicycle motor end cover

Technical field

The utility model relates to component of machine technical field, especially a kind of electric bicycle motor end cover.

Background technology

Electric vehicle motor cover plate is the indispensable part of electric motor car.Motor cover plate used in the market generally adopts aluminium to cast and produces, and need to carry out bilayer and throw limit, product processing technique is complicated, production cost bag, and environmental pollution is larger.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of reliable in quality, the electric bicycle motor end cover that easy to process, production cost is lower.

The utility model solves the technical scheme that its technical problem adopts: a kind of electric bicycle motor end cover, comprise end cap body, end cap body is the disc-shaped structure of indent, there is bottom described disc-shaped structure the annular table of evagination, the dish mouth circumference extension of the disk of described end cap body forms a few word limits had in " several " word structure, and described a few word limit evenly has circular mounting through hole.

Further, outside the disk bottom of end cap body, annularly platform is evenly equipped with trapezoidal handle.

Further, end cap body, trapezoidal handle and annular table are structure as a whole.

In order to better cost-saving, end cap body, trapezoidal handle and annular table are cast iron quality.

The beneficial effects of the utility model are: the electric bicycle motor end cover that the utility model provides, and punching press is made, and processing technology is simple, and production cost is low and intensity is highly dense seals, reliable in quality.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the utility model is further illustrated.

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

Fig. 2 is the schematic cross-section of A-A in Fig. 1.

In figure, the trapezoidal handle of through hole 5. is installed on 1. end cap body 2. annular table more than 3. word limits 4.

Embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.

A kind of electric bicycle motor end cover as depicted in figs. 1 and 2, comprise end cap body 1, end cap body 1 is the disc-shaped structure of indent, has the annular table 2 of evagination bottom described disc-shaped structure, and outside the disk bottom of end cap body 1, annularly platform 2 is evenly equipped with trapezoidal handle 5.Further, end cap body 1, trapezoidal handle 5 are structure as a whole with annular table 2, be cast iron quality, the direct punching press of punch press can be used to be formed, not only reduce production cost, relative to common aluminium casting end cap, cast iron end cap not only can satisfy the demands in intensity, and processing and manufacturing environmental pollution is less.

The dish mouth circumference extension of the disk of end cap body 1 forms a few word limits 3 had in " several " word structure.A few word limit 3 then evenly has circular mounting through hole 4.Punching machine mold can be utilized to manufacture end cap, and double-deck bending, punching press forms a few word limit 3.The bilayer of the aluminium casting end cap course of processing is thrown limit technique and is simplified, convenient processing.A few word limit 3 is opened and installs through hole 4, when installing end cap, a few word limit 3 can provide certain elasticity, improves the sealing property of electric motor end cap.

Above-mentioned execution mode is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection range of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
