Description

Technical Field

[0001] This utility model relates to the field of power-assisted bicycle technology, and in particular to a high-efficiency motor mounting component for power-assisted bicycles. Background Technology

[0002] An electric-assisted bicycle is a mode of transportation that combines traditional bicycle technology with electric drive technology. It is equipped with an electric motor and battery system to provide additional power support to the rider while riding. While the electric motor provides extra power, it does not completely replace human power. Current electric-assisted bicycles employ a cumbersome installation method for the motor, making it difficult for users to accurately position it. This not only consumes a significant amount of time and effort in repeated adjustments, causing considerable inconvenience to users and reducing their efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency motor mounting component for power-assisted bicycles.

[0004] This utility model is achieved using the following technical solution:

[0005] A high-efficiency motor mounting assembly for a power-assisted bicycle includes a frame, a flange ring fixedly connected to the outer wall of the frame, a connecting screw slidably connected inside the flange ring, a nut threadedly connected to the connecting screw, a first flange ring slidably connected to the outer wall of the connecting screw, and an outer protective shell fixedly connected to the inner wall of the first flange ring.

[0006] In a further improvement, several connecting screws are provided, and these connecting screws are evenly arranged around the first flange ring as the center. Similarly, several nuts are provided, and these nuts are evenly arranged around the first flange ring as the center.

[0007] A brushless motor is installed inside the outer protective shell. A first flange ring is fixed to the outer wall of the outer protective shell, and a flange ring is fixed to the outer wall of the frame. At this time, the operator slides the connecting screw inside the first flange ring and the flange ring, and at the same time, the operator uses the nut to tightly fit the first flange ring and the flange ring together, thereby completing the installation of the brushless motor. The first flange ring and the flange ring help the user to accurately position and ensure the correct position of the brushless motor, reducing the time spent on repeated adjustments and improving the user's efficiency.

[0008] In a further improvement, a wheel axle is rotatably connected inside the frame, and a cross-shaped locking groove is provided on the outer side of the wheel axle. A cross-shaped locking block is slidably connected to the outer surface of the cross-shaped locking groove.

[0009] In a further improvement, a connecting rod is fixedly connected inside the cross-shaped locking block, and a brushless motor is fixedly connected to the end of the connecting rod away from the cross-shaped locking block. A connecting plate is fixedly connected to the end of the brushless motor away from the connecting rod.

[0010] In a further improvement, a slider is fixedly connected to the outer wall of the connecting plate, and the slider is slidably connected to the inner wall of the outer protective shell, and a groove is provided on the inner wall of the outer protective shell.

[0011] The operator uses a hex wrench to rotate the internal hexagonal socket, which is then fixed to the threaded rod. The threaded rod is then threadedly connected to the connecting plate, causing the connecting plate to slide on the outer wall of the slide groove via a slider. This disengages the cross-shaped locking block from the cross-shaped locking groove, thereby improving the service life of the brushless motor and preventing hard damage to the internal parts caused by the cross-shaped locking block rotating the internal parts of the brushless motor when it is not in use.

[0012] In a further improvement, the slide groove is slidably connected to the slider, and a threaded rod is threadedly connected inside the connecting plate, with the threaded rod rotatably connected inside the outer protective shell.

[0013] In a further improvement, an internal hexagonal pin is fixedly connected to the end of the threaded rod away from the cross-shaped locking block, and a threaded plug is threadedly connected inside the outer protective shell. The threaded plug prevents rainwater and other substances from entering the interior of the outer protective shell, thereby effectively protecting the safety of the brushless motor.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a first flange ring is fixed to the outer wall of the outer protective shell, and a flange ring is fixed to the outer wall of the frame. The operator slides the connecting screw inside the first flange ring and the flange ring, and simultaneously uses a nut to tightly fit the first flange ring and the flange ring together, thus completing the installation of the brushless motor. The first flange ring and the flange ring help the user to accurately position the brushless motor, ensuring the correct position and reducing the time spent on repeated adjustments, thereby improving user efficiency. The internal hexagonal column is fixed to the threaded rod, which is threadedly connected to the connecting plate. This allows the connecting plate to slide on the outer wall of the slide groove via a slider, causing the cross-locking block to disengage from the cross-locking groove. This improves the service life of the brushless motor and prevents damage to internal parts caused by the cross-locking block rotating the internal components when not in use.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] A high-efficiency motor mounting assembly for a power-assisted bicycle includes a frame 1, a flange ring 2 fixedly connected to the outer wall of the frame 1, a connecting screw 3 slidably connected inside the flange ring 2, a nut 4 threadedly connected to the connecting screw 3, a first flange ring 5 slidably connected to the outer wall of the connecting screw 3, and an outer protective shell 6 fixedly connected to the inner wall of the first flange ring 5.

[0024] There are several connecting screws 3, which are evenly arranged around the first flange ring 5. There are also several nuts 4, which are evenly arranged around the first flange ring 5.

[0025] The frame 1 is rotatably connected to a wheel axle 7. A cross lock groove 8 is provided on the outer side of the wheel axle 7. A cross lock block 9 is slidably connected to the outer surface of the cross lock groove 8.

[0026] A connecting rod 10 is fixedly connected inside the cross lock block 9. A brushless motor 11 is fixedly connected to the end of the connecting rod 10 away from the cross lock block 9. A connecting plate 12 is fixedly connected to the end of the brushless motor 11 away from the connecting rod 10.

[0027] A slider 13 is fixedly connected to the outer wall of the connecting plate 12. The slider 13 is slidably connected to the inner wall of the outer protective shell 6. A groove 14 is provided on the inner wall of the outer protective shell 6.

[0028] The slide groove 14 is slidably connected to the slider 13, and the connecting plate 12 is internally threaded with a threaded rod 15, which is rotatably connected inside the outer protective shell 6.

[0029] The end of the threaded rod 15 away from the cross locking block 9 is fixedly connected to an internal hexagonal column 16, and the outer protective shell 6 is internally threadedly connected to a threaded plug rod 17.

[0030] The working principle is as follows: A brushless motor 11 is installed inside the outer protective shell 6. A first flange ring 5 is fixed to the outer wall of the outer protective shell 6, and a flange ring 2 is fixed to the outer wall of the frame 1. The operator slides the connecting screw 3 inside the first flange ring 5 and flange ring 2, and simultaneously uses the nut 4 to tightly fit the first flange ring 5 and flange ring 2 together, thus completing the installation of the brushless motor 11. The first flange ring 5 and flange ring 2 help the user to accurately position and ensure the correct position of the brushless motor 11, reducing the time spent on repeated adjustments and improving user efficiency. Inside the frame 1, the wheel axle 7 rotates. A cross-shaped locking groove 8 is opened on the outer wall of the wheel axle 7, and the cross-shaped locking groove 8 contacts the cross-shaped locking block 9. The cross-shaped locking block 9 is fixed to the connecting rod 10, and the connecting rod 10 is connected to the brushless motor 11. The brushless motor 11 is fixed to the connecting plate 12. The wheel axle 7 is rotated by the cross locking block 9, thus saving manual labor. When the brushless motor 11 is not in use, the operator can rotate the internal hexagonal column 16 with a hexagonal wrench. The internal hexagonal column 16 is fixed to the threaded rod 15, which is threadedly connected to the connecting plate 12. This allows the connecting plate 12 to slide on the outer wall of the slide groove 14 via the slider 13, causing the cross locking block 9 to disengage from the cross locking groove 8. This improves the service life of the brushless motor 11 and prevents hard damage to the internal parts of the brushless motor 11 caused by the cross locking block 9 rotating when not in use. At the same time, a threaded plug rod 17 is threadedly connected inside the outer protective shell 6 to prevent rainwater from entering the outer protective shell 6, thus effectively protecting the safety of the brushless motor 11.
