Description

Technical Field

[0001] This utility model relates to the technical field of center of gravity stabilization adjustment devices, and in particular to a center of gravity stabilization adjustment device for an electric bicycle. Background Technology

[0002] Electric bicycles, as a convenient and environmentally friendly mode of transportation, have played an increasingly important role in short-distance urban travel in recent years. However, the stability of electric bicycles has always been one of the key factors restricting their safety and comfort. A center-of-gravity stabilization device is a system that uses gyroscope technology to monitor and adjust the center-of-gravity position of the electric bicycle in real time. As a sensor capable of sensing and measuring changes in angular velocity, the gyroscope can accurately capture changes in the electric bicycle's posture, including tilt angle and direction. By transmitting this data to the control system in real time, the device can quickly calculate the vehicle's center-of-gravity position and adjust the vehicle's posture through actuators such as motors, thereby maintaining the vehicle's stability.

[0003] While center-of-gravity (COP) adjustment devices play a crucial role in improving the stability of e-bikes, the noise they generate during operation cannot be ignored. Because these devices contain complex mechanical structures and electronic components such as motors, gears, and sensors, these parts vibrate and rub during operation, producing noise. When the COP adjustment device is directly installed inside the e-bike's casing, the sound insulation of the outer shell alone is often insufficient to reduce noise. This is because the e-bike's casing design primarily focuses on protecting internal components from external environmental corrosion, rather than sound insulation. Therefore, when the device is operating, noise can be transmitted to the outside through gaps in the casing or through resonance, causing unnecessary disturbance and discomfort to the rider. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a center of gravity stabilization adjustment device for electric bicycles, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an electric bicycle center of gravity stabilization adjustment device, including an adjustment frame. Two symmetrically arranged first motors are fixedly connected to the inner wall of the adjustment frame. The output end of each first motor is connected to a drive frame via a belt drive structure. Both drive frames are rotatably connected to the adjustment frame via bearings. A second motor is fixedly connected to the bottom surface of the drive frame. A flywheel is fixedly connected to the output end of the second motor. Both flywheels are located inside the adjustment frame. Frames are fixedly connected to the top and bottom surfaces of the adjustment frame, and a U-shaped frame is fixedly connected between the two frames. The U-shaped frame is connected to the two frames by bolts. The top and bottom of the U-shaped frame are provided with assembly slots. A sound insulation plate is slidably connected to the inner wall of each assembly slot. The two flywheels are corresponding to the sound insulation plates. The top and bottom of the U-shaped frame are provided with two symmetrically arranged grooves. A control plate is slidably connected to the inner wall of each groove. Two symmetrically arranged springs are fixedly connected between the control plate and the U-shaped frame. The two springs are located on the inner wall of the groove. Two symmetrically arranged locking rods are fixedly connected to the side of the control plate away from the springs. The locking rods pass through the U-shaped frame and engage with the sound insulation plates.

[0007] Preferably, in any of the above solutions, the inner wall of the U-shaped frame is fixedly connected with a number of symmetrically arranged guide plates, and each frame has guide grooves on its left and right sides, and the guide plates are slidably connected to the frame through the guide grooves.

[0008] Preferably, in any of the above solutions, two symmetrically arranged limiting pins are fixedly connected to one side of the drive frame, and two symmetrically arranged arc-shaped limiting grooves are opened on the inner wall of the adjustment frame.

[0009] Preferably, one side of the adjustment frame is fixedly connected to two symmetrically arranged clamping plates, and the adjustment frame is engaged with the U-shaped frame through the two clamping plates.

[0010] Preferably, in any of the above solutions, the inner wall of the assembly slot is fixedly connected with a number of symmetrically arranged positioning pins, and the sound insulation plate is provided with a number of symmetrically arranged positioning holes on the side near the flywheel.

[0011] Preferably, from any of the above solutions, the sound insulation panel has locking holes on both the left and right sides, and the locking rod passes through the U-shaped frame and engages with the sound insulation panel through the locking holes.

[0013] 1. Through optimized design and structural innovation, the vehicle's center of gravity stability and user experience have been significantly improved. Firstly, the two primary motors within the adjustment frame drive the drive frame via a belt drive structure. Combined with the secondary motor and flywheel, this dynamically adjusts the vehicle's center of gravity, enhancing stability during cornering, acceleration, and braking. The sound insulation panel effectively reduces flywheel noise, improving the device's noise reduction effect. Furthermore, the sound insulation panel's snap-fit ​​connection to the U-shaped frame facilitates disassembly and replacement, enhancing the device's maintenance convenience.

[0014] 2. The guide plate inside the U-shaped frame slides through the guide groove of the frame, ensuring stable operation and precise adjustment of the device. The limiting pin on the drive frame engages with the arc-shaped limiting groove of the adjustment frame, limiting the range of motion of the drive frame and preventing structural damage caused by over-adjustment.

Through the above design, this utility model not only achieves dynamic adjustment and stability improvement of the electric bicycle's center of gravity, but also takes into account noise reduction, maintenance convenience, and structural stability, making it suitable for various scenarios such as urban commuting and mountain biking, and has broad application prospects.
