[0001] This utility model belongs to the technical field of electric assist bicycle motor torque assembly, and particularly relates to an electric assist bicycle motor torque assembly. Background Technology

[0002] With increasing environmental awareness, people's demand for green travel methods is constantly growing. Bicycles, as a zero-emission mode of transportation, are highly favored, but bicycles alone cannot meet people's needs for fast and effortless travel in certain situations.

[0003] Meanwhile, many people also hope to get some exercise while cycling, rather than relying entirely on motor drive. Therefore, there is a need for a motor torque assembly that can intelligently sense the rider's effort and provide just the right amount of assistance, satisfying users' desire for both easy riding and physical exercise. Continuous advancements in motor, sensor, and control technologies have made it possible to develop more advanced motor torque assemblies for electric bicycles. The emergence of high-performance permanent magnet motors, high-precision torque sensors, and advanced microcontrollers has enabled the development of motor torque assemblies with smoother power output, higher efficiency, and greater intelligence, thus driving the development of the electric bicycle industry. However, in practical use, it has been found that existing torque assemblies often have a portion exposed, making them prone to damage over time, and dust accumulation can negatively impact the device's performance. Utility Model Content

[0004] In order to solve the problems mentioned above, the existing torque assemblies are usually partially exposed in actual use, which are prone to damage after long-term use and dust accumulation, thus affecting the performance of the device, the purpose of this utility model is to provide a torque assembly for a power-assisted bicycle motor.

[0005] To achieve the above objectives, this utility model proposes a torque assembly for a power-assisted bicycle motor, comprising a torque assembly, characterized in that: a connecting cylinder is fixedly installed on the outside of the torque assembly, multiple rotating shafts are rotatably installed above the connecting cylinder, a protective cylinder is rotatably installed above the rotating shafts, and multiple circular grooves are opened inside the connecting cylinder, with dustproof holes fixedly installed inside the circular grooves.

[0006] In one example, the connecting cylinder is hollow.

[0007] In one example, the shafts are arranged horizontally.

[0008] In one example, a horizontal bar is provided above the connecting cylinder.

[0009] In one example, a support plate is fixedly installed below the crossbar, and the support plate is connected to the rotating shaft.

[0010] In one example, a first guide plate is fixedly installed inside the protective cylinder on one side above the support plate, and a second guide plate is fixedly installed on the other side.

[0011] In one example, a partition is fixedly installed at the junction of the first guide plate and the second guide plate.

[0012] In one example, the first guide plate and the second guide plate are symmetrical.

[0013] In one example, support rods are fixedly installed at the bottom ends of the first guide plate and the second guide plate.

[0014] The power assist bicycle motor torque assembly proposed in this utility model can bring the following beneficial effects:

[0015] First, the installation of the connecting cylinder prevents the torque assembly from being affected by external factors during operation, improving work efficiency and enhancing the overall safety of the device. The installation of the rotating shaft allows for a smoother connection between the connecting cylinder and the protective cylinder, improving the stability of the device during rotation. The circular groove inside the connecting cylinder enhances its air permeability, and dustproof holes within the groove effectively prevent dust from falling into the torque assembly, ensuring the stability of the device and reducing its failure rate.

[0016] II. The cooperation between the support plate and the rotating shaft enhances the dustproof performance of the device while maintaining overall stability. The installation of the clamping plate further improves stability. The installation of the first and second guide plates allows dust to be expelled from the device more quickly, preventing it from affecting operation. The installation of the partition plate improves dust removal efficiency, effectively increasing working efficiency and ensuring smoother operation. The symmetrical arrangement of the first and second guide plates diverts dust in two directions, enhancing dust removal. The installation of the support rod further stabilizes the first and second guide plates, preventing damage from excessive rotational speed and ensuring their performance.

[0030] like Figures 1-6 As shown, this utility model provides a torque assembly for a power-assisted bicycle motor, including a torque assembly 1. A connecting cylinder 2 is fixedly installed on the outside of the torque assembly 1. The connecting cylinder 2 is hollow, and its installation prevents the torque assembly 1 from being affected by external factors during operation, improving work efficiency and enhancing the overall safety of the device. Multiple rotating shafts 102 are rotatably mounted above the connecting cylinder 2, arranged horizontally. A protective cylinder 3 is rotatably mounted above the rotating shafts 102. The installation of the rotating shafts 102 allows for a smoother connection between the connecting cylinder 2 and the protective cylinder 3, improving the stability of the device during rotation. Multiple circular grooves 8 are formed inside the connecting cylinder 2, and dustproof holes 101 are fixedly installed inside the circular grooves 8. The circular grooves 8 enhance the air permeability of the connecting cylinder 2, and the dustproof holes 101 effectively prevent dust from falling into the torque assembly 1, ensuring the stability of the device and reducing its failure rate.

[0031] Specifically, a horizontal bar 6 is provided above the connecting cylinder 2, and a support plate 7 is fixedly installed below the horizontal bar 6. The support plate 7 is connected to the rotating shaft 102. The cooperation between the support plate 7 and the rotating shaft 102 enhances the dustproof performance of the device while ensuring the overall stability of the device. A retaining plate 9 is provided inside the connecting cylinder 2, which improves the stability of the device. A first guide plate 4 is fixedly installed on one side above the support plate 7 inside the protective cylinder 3, and a second guide plate 202 is fixedly installed on the other side. The installation of the first guide plate 4 and the second guide plate 202 allows dust to be discharged from the device more quickly under the guidance of the guide plates, preventing it from affecting the operation of the device. A partition plate 201 is fixedly installed at the junction of the first guide plate 4 and the second guide plate 202. The installation of the partition plate 201 improves the dust removal effect of the device, effectively improves the working efficiency of the device, and makes the device operate more smoothly. The first guide plate 4 and the second guide plate 202 are symmetrical. This design can guide the dust out of the device in two directions, resulting in a better dust removal effect. Support rods 5 are fixedly installed at the bottom of the first guide plate 4 and the second guide plate 202. The installation of support rods 5 makes the stability of the first guide plate 4 and the second guide plate 202 better, and will not be damaged due to excessive rotation speed, thus affecting their performance.

[0032] Working Principle: When the torque assembly 1 is running, the protective cylinder 3 rotates in conjunction with the rotating shaft 102. Since the connecting cylinder 2 is connected to the rotating shaft 102, its working efficiency is higher and its rotation is more stable. During this rotation, the circular groove 8 experiences an outward force, and air is discharged outward through the circular groove 8. Guided upward by the pressing plate 9, the air is discharged upwards. As it passes inside the protective cylinder 3, the air is guided out by the guide plates on both sides. Because the guide plates on both sides are symmetrical and have a partition 201 in the middle, the exhaust effect is better, and dust can be discharged from the device more quickly, effectively improving the device's working efficiency. The device operates more safely and efficiently within the protective cylinder 3, resulting in higher safety and less susceptibility to damage.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
