Description

Technical Field

[0001] This utility model belongs to the field of auxiliary technology for the maintenance of three-wheeled electric motorcycles, and particularly relates to a quick auxiliary disassembly and lifting device for the rear wheel of a three-wheeled electric motorcycle. Background Technology

[0002] Due to their practicality in carrying goods and passengers, three-wheeled electric motorcycles are widely used in urban and rural transportation. During use, the left and right rear tires of these motorcycles can suffer varying degrees of damage, requiring timely repair or replacement. Current technology lacks a dedicated quick-lifting auxiliary device for these tires. Repairs require manual support using mechanical or hydraulic jacks. Typically, the driver enters under the vehicle to install the jacks, which then lift the rear of the vehicle for repairs. Furthermore, current technology has the following drawbacks:

[0003] 1. Vehicles on the market do not have a lifting mechanism installed on the vehicle, requiring the purchase of a separate mechanical or hydraulic jack, which increases the user's cost;

[0004] 2. Vehicle-mounted mechanical or hydraulic jacks need to be placed on the vehicle, which not only takes up space but is also easy to lose. In addition, ordinary mechanical jacks are prone to rust, affecting their use, and hydraulic jacks cannot be used normally in extremely cold weather.

[0005] 3. Ordinary mechanical or hydraulic jacks require the driver to enter under the vehicle to operate them. There is no fixed point of contact between the jack and the vehicle. When lifting, the entire vehicle shakes in the front, back, left, and right, which can easily lead to slippage. The operation is cumbersome and the support stability is poor, posing a safety hazard. Moreover, it is difficult to accurately lift the left and right rear wheels, resulting in low disassembly efficiency and increasing the difficulty and time cost of maintenance. Utility Model Content
