Abstract
The utility model provides a connecting structure of a flat fork and a motor of an electrical bicycle. The connecting structure comprises the flat fork and the motor, wherein the flat fork is in a shape like the Chinese character ''kai'' and is provided with a first support arm and a second support art, the tail end of the first support arm is fixedly arranged in a groove through an anti-pull sheet and a compression screw, the groove is formed in a motor outer casing at one side of the motor, the left side of the first support arm of the flat fork is processed with a motor wire outlet hole lug at the outer side of the motor, the motor wire outlet hole lug is attached with the first support arm, the second support arm is connected with a bearing seat of the flat fork through a connecting screw of the flat fork, the bearing seat of the flat fork is sheathed at one end of an output shaft of the motor through a bearing, the bearing seat of the flat fork is rotationally connected with the output shaft, and an inner ring of the bearing is fastened by a shaft end nut. The connecting structure of the flat fork and the motor of the electrical bicycle has the advantages that the connecting strength is high, the assembly flexibility is good, the manufacturing cost is low, the installation is convenient, and the like.
Description
Technical field
The utility model relates to a kind of connection structure, the connection structure of especially a kind of Electrical Bicycle chain stay and motor.
Background technology
The motor that conventional Electrical Bicycle is installed, motor shaft does not rotate, and by motor housing, drives wheel hub rotary work, and chain stay is supported on the axle stretching out at motor two ends.And for the Electrical Bicycle of particular design, motor housing does not rotate, and by the output shaft of motor, rotarily drives wheel hub work, if this design adopts the electrical installation of conventional Electrical Bicycle, cannot install.
Utility model content
Problem to be solved in the utility model is the deficiency overcoming in background technology, and the connection structure of a kind of Electrical Bicycle chain stay and motor is provided, this connection structure, and Joint strenght is high, easy to assembly, low cost of manufacture.
For addressing the above problem, the utility model is taked following technical scheme:
The connection structure of a kind of Electrical Bicycle chain stay of the present utility model and motor, comprise chain stay, motor, the structure of described chain stay is " opening " word shape, there is the first support arm and the second support arm, the end of described the first support arm is fixed on by anti-pulling-on piece and housing screw in the groove of motor housing formation of motor one side, the outside of described motor, in the left side of the first support arm of chain stay, be processed with the motor outlet wire hole lug with the first support arm laminating, described the second support arm is connected to bottom fork axis bearing by chain stay attaching screw, described bottom fork axis bearing is the one end at the output shaft of motor by bearing carrier ring, bottom fork axis bearing and output shaft form and are rotatably connected, the inner ring of described bearing tightens up by shaft end nut.
An innovative approach of the present utility model is: in the endoporus of described bottom fork axis bearing, be fixedly installed two back-up rings in a distance of bearing both sides.
The connection structure of a kind of Electrical Bicycle chain stay of the present utility model and motor, due to the outside at motor, in the left side of the first support arm of chain stay, be processed with the motor outlet wire hole lug with the first support arm laminating, this motor outlet wire hole lug plays the effect of supporting chain stay the first support arm, because the second support arm is connected to bottom fork axis bearing by chain stay attaching screw, bottom fork axis bearing is the one end at the output shaft of motor by bearing carrier ring, and bottom fork axis bearing and output shaft form and be rotatably connected.Therefore the connection structure of a kind of Electrical Bicycle chain stay of the present utility model and motor, Joint strenght is high, assembles flexiblely, also has low cost of manufacture, the advantage such as easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right elevation of Fig. 1.
The specific embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, the connection structure of a kind of Electrical Bicycle chain stay of the present utility model and motor, comprise chain stay 1, motor 2, the structure of described chain stay 1 is " opening " word shape, there is the first support arm 11 and the second support arm 12, the end of described the first support arm 11 is fixed in the groove that the motor housing 21 of motor 2 one sides forms by anti-pulling-on piece 3 and housing screw 4, the outside of described motor 2, left side at the first support arm 11 of chain stay 1 is processed with the motor outlet wire hole lug 22 of fitting with the first support arm 11, described the second support arm 12 is connected to bottom fork axis bearing 5 by chain stay attaching screw 10, described bottom fork axis bearing 5 is enclosed within one end of the output shaft 8 of motor 2 by bearing 6, bottom fork axis bearing 5 forms and is rotatably connected with output shaft 8, the inner ring of described bearing 6 tightens up by shaft end nut 9.
In the endoporus of described bottom fork axis bearing 5, in a distance of bearing 6 both sides, be fixedly installed two back-up rings 7.
Should be noted that; the foregoing is only preferred embodiment of the present utility model, be not limited to the present embodiment, all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
