Abstract
The embodiment of the utility model provides a motor shell structure of an electric outboard motor, which comprises a shell, a front cover and a rear cover, wherein the connecting part of the front cover and the shell and the connecting part of the rear cover and the shell are all hidden, so that the front cover, the shell and the rear cover can jointly form a sealed shell with a streamline-shaped peripheral surface, the resistance of the motor shell in water is effectively reduced, and the efficiency of the whole motor is improved.
Description
Technical Field
The utility model relates to the field of outboard engines, in particular to a motor shell structure of an electric outboard engine.
Background
Currently, an electric outboard engine mostly adopts an underwater motor structure, and the motor is arranged underwater as power, so that the motor and a motor controller need to be sealed in an underwater shell. The conventional motor housing structure is generally shown in fig. 1 and 2, and the front cover 2 and the rear cover 3 are fixedly connected to the housing 1 by using the screws 4, so that corresponding screw mounting holes are required to be formed in the front cover 2, the rear cover 3 and the housing 1, and the mounting holes are generally protruded out of the surface of the housing due to the limitation of the wall thickness of the housing, so that the overall flow linearity of the motor is affected, the resistance of the motor in water is increased, and the overall efficiency is reduced.
Disclosure of Invention
In order to solve the technical problems, an embodiment of the utility model provides a motor housing structure of an electric outboard engine.
The motor shell structure of the electric outboard engine comprises a shell, a front cover and a rear cover, wherein the front cover and the rear cover are respectively connected to the front end and the rear end of the shell in a sealing mode, and the connection positions of the front cover and the shell and the connection positions of the rear cover and the shell are all hidden, so that the front cover, the shell and the rear cover can jointly form a sealing shell with streamline-shaped peripheral surfaces.
Optionally, the upstream surface of the front cover is a streamline curved surface.
Optionally, the front cover and the rear cover are both in threaded connection with the casing, and the connection parts are both provided with sealing gaskets.
Optionally, the front cover and the screw thread connected with the casing are fixed by screw thread glue.
The embodiment of the utility model has the following beneficial effects: the connecting part of the front cover and the shell and the connecting part of the rear cover and the shell are all hidden, so that the front cover, the shell and the rear cover can jointly form a sealed shell with a streamline outer peripheral surface, the resistance of the motor shell in water is effectively reduced, and the efficiency of the whole machine is improved.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the utility model. In the present utility model, unless otherwise indicated, terms such as "front" and "rear" and the like are used to generally refer to the front and rear of the device in actual use or in an operational state, and particularly to the direction of the drawing in the figures; while "inner" and "outer" are for the outline of the device.
Referring to fig. 3 and 4, an embodiment of the present utility model provides a motor housing structure of an electric outboard motor, which includes a casing 1, a front cover 2 and a rear cover 3, wherein the front cover 2 and the rear cover 3 are respectively connected to front and rear ends of the casing 1 in a sealing manner, so that the front cover 2, the casing 1 and the rear cover 3 can form a sealed housing together, thereby providing a closed waterproof space for the motor under water.
In order to reduce the resistance of the sealing shell in water and improve the efficiency of the whole machine, the connecting part of the front cover 2 and the shell 1 and the connecting part of the rear cover 3 and the shell 1 are all hidden, so that the outer side walls of the front cover 2, the shell 1 and the rear cover 3 can jointly form the streamline-shaped outer peripheral surface of the sealing shell. Further, the upstream surface of the front cover 2 may be designed to be a hemispherical or other streamline curved surface to reduce the resistance.
As an alternative implementation manner, the front cover 2 and the rear cover 3 in this embodiment are fixedly connected with the casing 1 through a threaded connection manner, sealing gaskets such as O-shaped rings are arranged at the connection positions to carry out waterproof sealing, and the threads connected are preferably fixed through a thread adhesive to prevent loosening. Of course, the front cover 2 and the rear cover 3 may be connected to the casing 1 by fastening, riveting, welding, or the like, and the connection point may be hidden inside the casing or in the joint, so that the fluidity of the whole casing is not affected.
The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of the above examples is only for aiding in understanding the technical solution of the present utility model and its core ideas; those of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
