Problems solved by technology

[0003] It is worth noting that the current wheel-hub motors use a single motor as the power source, and the motor is designed to meet the high current and high torque requirements during starting. The motor coil must be composed of wire diameters that meet the starting current capacity, and the overall The appearance of the coil must conform to the principle of small size and flatness, which leads to the special specifications of the hub motor and is only specially manufactured for use with electric bicycles. Therefore, the cost of the current hub motor is quite expensive and has many restrictions;
[0004] From the above explanations, it can be seen that the current wheel-hub motors dedicated to electric bicycles are limited by the conditions of high starting current and flat overall volume, and the disadvantages of high cost are not conducive to the development of the industry. It is really necessary to make further breakthroughs , so as to better meet the actual needs of the industry

Embodiment Construction

[0024] For the present invention to achieve the above-mentioned purpose, the technology, means and other effects adopted, hereby give a preferred feasible embodiment and describe it in detail in conjunction with the drawings; at first, please refer to Figure 1-5 As shown, the embodiment of the present invention provides a structure in which a plurality of electric motors are used to form an in-wheel motor. The main purpose is to integrate a plurality of independent motors into the hub through a drive chainring and a spindle, so that it can be operated according to the actual road conditions. Adequate power output, where:

[0025] The wheel hub 20 is the wheel hub 20 of the electric bicycle 60 (it can be a front wheel or a rear wheel). There is an accommodating space 21 formed in the wheel hub 20, and a perforation is provided on the side wall of the accommodating space 21 of the wheel hub 20, and can be assembled. A bearing 22 is inside; the accommodating space 21 of the whee...

Abstract

The invention relates to a wheel hub constructed with multiple motors. The invention is characterized in that multiple motors can be installed simultaneously in the wheel hub as the power source and each motor output power can be reduced dramatically as each motor only need to bare local power output. The number of the motors can be increased or decreased according to the requirement of the power output.

Description

technical field [0001] The present invention is a structure in which a hub motor is formed by a plurality of electric motors, and especially refers to a bicycle power structure design specially used for an electric bicycle in which the motor is concealed and installed inside the bicycle hub. Background technique [0002] see Figure 8 As shown, this is a design in which the electric motor 11 is hidden and assembled inside the bicycle hub 10. It is mainly after a set of assembly space 12 is formed in the wheel hub 10, and then the electric motor 11 is assembled inside the assembly space 12, and transparently Pass the cover 13 and seal and cover from the side of the hub 10; in this way, the motor component is concealed in the assembly space of the hub, not only the appearance is more neat and beautiful, but also because the motor component is completely hidden and covered, it can effectively reduce the The motor is damaged by collision, fouling and other reasons; here, the des...
