Description

Technical Field

[0001] This utility model relates to the field of electric off-road motorcycles, specifically a shock absorption mechanism for electric off-road motorcycles. Background Technology

[0002] Electric off-road motorcycles combine electric technology with off-road performance. Powered by electricity, they reduce reliance on fossil fuels and offer advantages such as environmental friendliness, energy efficiency, and low noise. Equipped with high-performance electric motors and battery packs, they provide strong power output and long range. Their suspension systems and tire designs are optimized for off-road driving, enabling them to handle rough roads and challenging terrain.

[0003] Existing electric off-road motorcycles use shock-absorbing mechanisms between the seat and frame. These mechanisms absorb and mitigate impacts from the road surface, providing a comfortable riding experience. Through internal components such as damping oil and springs, the shock-absorbing mechanisms effectively absorb and mitigate road impacts, reducing bumps during riding and improving comfort. However, existing shock-absorbing mechanisms for electric off-road motorcycles still have the following problems during use:

[0004] Existing shock absorption mechanisms in electric off-road motorcycles can be adjusted via a threaded knob on the external thread of the air-fuel mixture cylinder, allowing for adjustable spring elasticity and improving riding experience and comfort. However, during operation, the threaded knob and the external thread on the air-fuel mixture cylinder are susceptible to vibration, potentially causing loosening between them. This affects the adjustable spring elasticity, further reducing riding experience and comfort. Therefore, it is necessary to develop a new shock absorption mechanism for electric off-road motorcycles to address this issue. Utility Model Content

[0005] To address the shortcomings of existing technologies, the threaded knob and the external thread on the oil-gas mixing cylinder of existing electric off-road motorcycles are easily affected by vibration during operation, causing loosening between the threaded knob and the external thread on the oil-gas mixing cylinder.

[0040] In this utility model, the power battery 12 on the electric motorcycle body 10 is charged through the power interface 13, which makes it convenient for the rider to ride the electric motorcycle body 10.

[0041] Working principle: The threaded knob 2006 rotates and moves on the external thread 2005, making the elasticity of the telescopic spring 2010 adjustable. At this time, the arc block 2304 rotates on the rotating ring groove 2302, and the rotating ring 2303 rotates inside the threaded knob 2006. The guide block 2306 moves on the assembly block 22. After the position is adjusted, the telescopic button 2118 is pressed, causing the elastic spring 2117 to contract in the inner cavity 2116. At this time, the pressing block 2113 can be pressed, and the adjusting block 2112 moves on the traction frame 2110 and the operating block 2102 until the telescopic button 2118 can move on the traction frame. The locking hole 2111 on 2110 is engaged. At this time, under the action of the adjusting rod 2115, the movable block 2105 moves towards each other on the guide rod 2104. The movable block 2105 drives the extension rod 2108 on the crossbar 2107 to move. The extension rod 2108 drives the positioning rod 2109 to pass through the assembly block 22 and insert into the positioning hole 2301 on the guide block 2306. This increases the stability of the threaded knob 2006 on the external thread 2005, prevents the threaded knob 2006 and the external thread 2005 on the oil-gas mixing cylinder 2004 from being loosened by vibration, improves the operation effect, and further improves the riding experience and comfort.
