Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle battery replacement, and in particular to a rapid battery replacement mechanism for an unmanned wide-body electric vehicle. Background Art

[0002] An electric vehicle is a vehicle that uses an onboard power source as its motive force, uses an electric motor to drive the wheels, and complies with various requirements of road traffic and safety regulations. It uses electricity stored in a power battery to start. When the power battery is exhausted, it needs to be charged immediately to ensure the normal driving of the electric vehicle. Although charging facilities are being continuously improved in various places to make charging more convenient, when users are pressed for time, in order to avoid excessive charging time, the main method of replacing the power battery of the electric vehicle is to solve the above problem. When the power battery is low, you can go to the charging station to directly replace a fully charged battery pack. The battery replacement mechanism is generally complex and redundant in structure, and the operation is time-consuming and labor-intensive. Therefore, it is necessary to develop a battery replacement mechanism that is quick to operate and has a stable and reliable structure. The Chinese patent number is: CN116278698A, which discloses "A battery rack for battery replacement of new energy vehicles and a fast battery replacement system for new energy vehicles". In this patent, the battery is placed on a support shell. At this time, the battery can produce contact pressure on the pressure-bearing rod of the positioning component. The pressure-bearing rod under the contact pressure moves downward, and synchronously drives the connecting shaft to move downward until one end of the connecting shaft is separated from the bottom clamping hole of the slider. At this time, the side spring rod can push the slider and the positioning plate, and the other set of positioning components is also triggered synchronously to achieve rapid positioning of the battery by the two positioning plates. Through this design, the battery can be placed and positioned at the same time.

[0021] The present invention provides a fast battery replacement mechanism for an unmanned wide-body electric vehicle. It has the following beneficial effects:

[0022] 1. The fast battery replacement mechanism of the unmanned wide-body tram, when the battery pack is on the inner side of the mating component, the rotating component rotates on the surface of the supporting component, and the matching hydraulic cylinder drives the limit component to move upward, and the limit component can completely enter the interior of the mating component, and the inner side of the mating component faces the limit component for firm support.
