Description

Technical Field

[0001] This application relates to the field of bicycle assist motor technology, and more specifically, to a bicycle assist motor that is easy to install. Background Technology

[0002] A power-assisted bicycle is a new type of two-wheeled vehicle, belonging to the category of bicycles. It uses batteries as an auxiliary power source, is equipped with a motor, and has a power assistance system. It is a new type of transportation tool that integrates human riding and motor assistance. In the field of power-assisted bicycles, there are two main types of motor installation positions: one is a mid-mounted motor, which is installed in the middle of the frame, i.e., the bottom bracket position; the other is installed in the wheel hub, which is called a hub motor.

[0003] According to the search, Chinese patent CN220032139U discloses a mid-drive motor for a power-assisted bicycle. It includes a first motor mounting shell and a second motor mounting shell. A fixing frame is fixedly connected to the inner wall of the second motor mounting shell. An ear plate is fixedly connected to the fixing frame via a first locking bolt. A mid-drive motor body is fixedly connected to one side of the ear plate. A drive shaft is located inside the mid-drive motor body, and a bushing is provided around the drive shaft. A drive gear is fixedly connected to the end of the drive shaft through the second motor mounting shell. This invention improves the rotational stability of the drive shaft by setting bearings and bushings inside the bushing, preventing the drive shaft from shaking at high speeds and affecting the working performance of the mid-drive motor body. The use of damping buffer springs and sound-absorbing felt plates absorbs the noise generated by the mid-drive motor body during operation, preventing excessive noise pollution.

[0004] Regarding the aforementioned technologies, the applicant believes that they lack a structure for quick assembly and disassembly of the motor mounting housing, making it inconvenient to quickly inspect the motor when needed. Furthermore, they lack a corresponding structure for slowing down the motor, resulting in excessively high motor speeds that compromise safety during use. Therefore, we propose a bicycle assist motor that is easy to install. Utility Model Content

A second bevel gear is fixedly connected to the surface of the rotating shaft body, and the second bevel gear meshes with the first bevel gear.

[0020] Furthermore, the shaft assembly also includes a chain gear fixedly connected to the surface of the shaft body.

[0021] By adopting the above technical solution, the rotation of the main body of the shaft will drive the chain gear to rotate.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] Please see Figure 1-4A convenient bicycle power-assist motor includes a base module 100 and an improved module 200. The base module 100 includes a bushing 110, and a connecting shell 120 is fixedly connected to the top of the bushing 110, and the connecting shell 120 communicates with the inner side of the bushing 110. The improved module 200 is disposed between the connecting shell 120 and the bushing 110. The improved module 200 includes a convenient disassembly and assembly component 210 disposed on the top of the connecting shell 120. A drive component 220 is disposed inside the connecting shell 120 and between the convenient disassembly and assembly component 210. A rotating shaft component 230 is disposed inside the bushing 110 and is connected to the drive component 220.

[0038] The easy-to-disassemble component 210 allows for quick disassembly and assembly of the motor housing when needed, facilitating motor maintenance. The drive component 220 features a deceleration structure, ensuring safety during use. The rotating shaft component 230 enables the drive component 220 to drive the rotating shaft component 230 to rotate, thus providing power assistance to the bicycle.

[0039] The easy-to-disassemble component 210 includes a connecting shell 211 movably connected to the top of the connecting shell 120. Multiple fixing pins 212 are threadedly connected to the connecting shell 211, and the multiple fixing pins 212 extend into the interior of the connecting shell 120. The easy-to-disassemble component 210 includes a threaded groove 213 formed on the connecting shell 211. An easy-to-remove shell 214 is threadedly connected to the top of the connecting shell 211 through the threaded groove 213. A vent 215 is provided on the easy-to-remove shell 214.

[0040] By rotating the easy-to-remove housing 214, the easy-to-remove housing 214 can be disassembled through the threaded groove 213, which facilitates the maintenance of the drive motor 224 by the staff and improves its practicality.

[0041] The drive assembly 220 includes a mounting base 221 fixedly connected to the inner side of the connecting housing 120. Four reduction gears 222 are rotatably connected to the inner side of the mounting base 221. A limit ring 223 is fixedly connected to the top of the mounting base 221. The drive assembly 220 also includes a drive motor 224 fixedly connected to the inside of the connecting housing 211. A drive gear 225 is fixedly connected to the output end of the drive motor 224, and the drive gear 225 meshes with the four reduction gears 222. The drive assembly 220 also includes a connecting rod 226 fixedly connected to the bottom of the drive gear 225.

[0043] The implementation principle of this application embodiment is as follows: When the drive motor 224 needs to be repaired, the easy-to-remove housing 214 is rotated first, so that the easy-to-remove housing 214 can be disassembled through the threaded groove 213, thereby facilitating the quick repair of the drive motor 224. When working, starting the drive motor 224 can drive the drive gear 225 to rotate, and the drive gear 225 will drive the four reduction gears 222 to rotate, thereby consuming the kinetic energy of the drive gear 225 and thus achieving the purpose of deceleration. The rotation of the drive gear 225 will also drive the first bevel gear 227 to rotate, the first bevel gear 227 will drive the second bevel gear 232 to rotate, the second bevel gear 232 will drive the rotating shaft body 231 to rotate, thereby driving the chain gear 233 to rotate, thereby achieving the assistance of the bicycle.
