Description

Technical Field

[0001] This utility model relates to the field of bicycle assist adjustment technology, specifically an assist adjustment device for shared electric bicycles. Background Technology

[0002] With the rapid development of internet technology, the sharing economy model has risen rapidly worldwide. Shared e-bikes, as a green and convenient mode of transportation, meet people's needs for short-distance travel. Under the backdrop of the sharing economy, improving the user experience and operational efficiency of shared e-bikes has become an important issue. The assist adjustment device is one of the key components of shared e-bikes.

[0003] The prior art discloses a bicycle intelligent power assist adjustment device based on strain gauge force sensing, with announcement number CN216546552U. The device includes a first crank, a second crank, and a double-headed axle connected to the first and second cranks at both ends. The device also includes a front cover fixed to the first crank, a strain gauge circuit board disposed on the end of the front cover away from the first crank and fixed to the front cover, and a rear cover controller disposed on the end of the strain gauge circuit board away from the first crank and electrically connected to the strain gauge circuit board. When the user pedals the bicycle, the first crank causes the strain gauge circuit board to deform under force, resulting in a change in resistance. The rear cover controller adjusts the power output of the external motor according to the change in resistance, thereby adjusting the power output according to the amount of force applied by the user when pedaling, thus achieving the purpose of assisting riding.

[0004] The aforementioned power assist adjustment device uses a strain gauge circuit board connected to the crank. When a user pedals the bicycle, the user's pedaling force is transmitted to the crank connected to it through the pedals. The crank is subjected to force and transmitted to the strain gauge circuit board fixedly connected to it to determine the pedaling force. However, the aforementioned device cannot determine the riding speed and gradient of the current road section based on the pedaling force, and cannot determine whether the power assist adjustment component needs to be activated based on the gradient and speed. The effect in use is not good and needs to be improved. Utility Model Content

With the locking of the mounting bolt 308, the height of the device can be adjusted. The sliding plate 307 has a threaded groove inside, and the rectangular plate 306 has a connecting screw hole with the same diameter as the threaded groove inside. The magnetic socket 303 has a rectangular groove inside. The area of ​​the two magnetic insertion blocks 305 is equal to the area of ​​the rectangular groove. The magnetic insertion blocks 305 are inserted into the inside of the magnetic socket 303.

[0028] The power steering adjustment detection device 2 includes a connecting plate 201, a crank 202, a limiting ring 203, an inner sliding column 204, a vertical plate 205, an inner connecting column 206, a connecting column 207, and a bearing 208. The connecting plate 201 is fixedly connected to the front of the speed control device housing 1. The crank 202 is connected to the bottom of the connecting plate 201. The limiting ring 203 is fixedly connected to the bottom front of the crank 202. The bearing 208 is fixedly connected to the bottom front of the crank 202.

A pressure sensor is set in the inner ring to help detect the speed. The side under pressure also represents one rotation, which can also help calculate the speed. When the speed is too low, the assist adjustment device can provide a certain amount of auxiliary power to the user, reducing the riding burden and improving riding comfort and efficiency. The assist adjustment device is located inside the speed control device housing 1, providing a clockwise driving force to the connecting column 207 to help rotate and achieve speed increase. The device has a gyroscope 4 that can detect road slope, allowing it to determine the current speed and slope of the road section. It can also determine whether the power assist adjustment component needs to be activated based on the slope and speed, resulting in good performance. A position adjustment device 3 is installed on the surface of the bicycle front fork 5, controlling the device's position. The device can slide on the surface of the bicycle front fork 5 by sliding the positioning plate 301, stopping when it reaches the desired position, and then pulling the sliding plate 307 to the right. This moves the sliding plate 307 closer to the front of the rear positioning plate 301. The mounting bolt 308 is then screwed into the sliding plate 307 and the rectangular plate 306 until they meet the bottom of the bicycle front fork 5, locking them in place. The elastic band 304 can then be pulled to stretch the device, and the magnetic insertion block 305 can be aligned with the top of the magnetic socket 303 and inserted to lock it, further limiting its position. A position adjustment mechanism is included to adjust the placement of the entire device, adapting it to different bicycle models and ensuring that the detection component below is aligned with the pedal crank, guaranteeing the device's normal operation.
