Description
Technical Field
The utility model relates to a technical field of electric bicycle part, in particular to motor stator axle construction.
Background
Electric bicycle drives the motion that wheel rotary motion realized the bicycle through the motor, owing to adopt the motor, the operation of motor needs to provide the power, and the power then needs the power cord to connect the motor, just can realize supplying power for the motor, the power cord passes through motor stator hub connection motor stator, and electric bicycle can meet different weather environment and road environment in the motion process, so absolute insulation is guaranteed to the motor, the insulation of motor shaft is the key, what current motor shaft insulation mode adopted is annotate sealed glue in the electric wire exit and realize, sealed glue of this kind of insulation mode coating drops easily, thereby the whole insulation of motor has been influenced, the quality of product has been influenced.
Disclosure of Invention
To the technical problem, the utility model provides a motor stator axle construction, it prevents effectively that sealed glue from droing easily, has guaranteed the whole of motor insulating to the quality of product has been guaranteed.
The technical scheme is as follows: the utility model provides a motor stator axle construction, its connecting portion that includes middle part motor stator installation department and both sides, one side connecting portion be provided with the through wires hole, the through wires hole incoming line sets up the connecting portion end, the through wires hole outlet sets up and is close to motor stator installation department, its characterized in that in the connecting portion side that has the through wires hole: and the opposite position of the wire outlet of the threading hole is provided with a glue injection hole.
The motor stator mounting part is further characterized by comprising a first motor mounting part, a second motor mounting part and a third motor mounting part in sequence, wherein the second motor mounting part is directly smaller than the first motor mounting part and the third motor mounting part, and the diameters of the first motor mounting part and the third motor mounting part are equal; the motor stator mounting part is provided with an oil groove; the glue injection hole is directly smaller than the wire outlet of the threading hole; the connecting part is of a screw structure.
The above structure of the utility model is adopted, because threading hole outlet relative position is provided with the injecting glue hole, pour into sealed glue into through the injecting glue mouth for sealed glue holds the power cord tightly, and it prevents effectively that sealed glue from droing easily, has guaranteed the whole insulation of motor, thereby has guaranteed the quality of product.
Drawings
Fig. 1 is a schematic view of the structure of the motor stator shaft of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in figure 1, the motor stator shaft structure comprises a middle motor stator mounting part 1 and connecting parts 2-1 and 2-2 on two sides, wherein a threading hole 3 is formed in the connecting part 2-2 on one side, a threading hole inlet 4 is formed in the end part of the connecting part 2-2, a threading hole outlet 5 is formed in the side, with the threading hole, of the connecting part 1-2 and close to the motor stator mounting part 1, a glue injection hole 6 is formed in the opposite position of the threading hole outlet 5, sealant is injected through the glue injection hole, so that the sealant tightly holds a power line, the sealant is effectively prevented from falling off easily, the overall insulation of a motor is guaranteed, and the quality of a product is guaranteed.
The motor stator mounting part sequentially comprises a first motor mounting part 1-1, a second motor mounting part 1-2 and a third motor mounting part 1-3, the second motor mounting part 1-2 is directly smaller than the first motor mounting part 1-1 and the third motor mounting part 1-3, the diameters of the first motor mounting part 1-1 and the third motor mounting part 1-3 are equal, and in the shaft machining process, the machining precision of the second motor mounting part is reduced, so that the machining efficiency is improved.
The motor stator mounting part 1 is provided with an oil groove 7, so that oil supply to a motor stator rotating part is realized, and abrasion of a motor stator shaft is prevented.
The diameter of the glue injection hole 6 is directly smaller than that of the threading hole 3, and the injected sealant is prevented from falling off after being cured.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
