Semi-automatic battery replacement manipulator of electric vehicle

Abstract

The invention discloses a semi-automatic battery replacement manipulator of an electric vehicle. The semi-automatic battery replacement manipulator of the electric vehicle is low in cost and capable of performing battery replacement operation in a small space. The semi-automatic battery replacement manipulator comprises a bottom plate and a supporting column. A rotatable cross beam is arranged atthe upper end of the supporting column and is driven by a motor III. A manipulator arm is mounted above the cross beam through a supporting structure and comprises a rectangular outer frame and a support, wherein the support is arranged in the outer frame in a sliding fit mode. A motor II is arranged at one longitudinal end of the outer frame. A roller II is mounted on a rotating shaft of the motor II. A translation rope is arranged on the roller II. The free end of the translation rope is fixedly connected with the support and used for driving the support to translate along a guide rail. A motor I and a roller I are arranged on the support in parallel and are in transmission through a gear pair. Two lifting ropes are arranged on the roller I. A long-strip plate is mounted on the lower portion of the support. Through holes are formed in the two ends of the long-strip plate. Each lifting rope penetrates through a corresponding through hole to extend downwards. The lower ends of the lifting ropes are fixedly used for hanging a hand claw of a battery.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a semi-automatic battery changing manipulator for electric vehicles. Background technique [0002] Compared with the ordinary charging mode, the battery swapping mode of the power station has obvious competitive advantages in terms of time and space. At present, it only takes at least 3 minutes to change the battery at the power station, which reduces the waiting time for consumers. [0003] Taking the space-time electric vehicle as an example, the system uses a stacker to realize the power battery exchange between the charging rack and the turntable, and uses a Cartesian coordinate manipulator to realize the power battery exchange between the intermediate platform and the electric vehicle, so that it can complete the replacement quickly and effectively car battery. The battery swapping devices are distributed symmetrically on both sides of the electric vehicle, and t...

Problems solved by technology

[0005] At present, the main factor that restricts the popularization and application of electric vehicles in China is that the quick-change battery packs of electric vehicles on the market have different structural designs, layout schemes, and layout positions, and it is impossible to unify the structural form of the battery-swapping manipulator. Some batteries The bags are arranged under the chassis floor, and some are arranged in the passenger compartment and the front cabin (such as Lifan 330 pure electric shared car). The disassembly and assembly methods of batteries in different locations are different, and the structural characteristics of the battery replacement manipulator and the battery disassembly and assembly methods are also different. Are not the same

For example, the battery pack of some electric vehicles is not a whole, but is realized by multiple independent battery packs connected in series and parallel. Each battery pack is independently packaged. In different positions, the weight of each battery pack is relatively light (such as Lifan 330 pure electric shared car). In this case, although the battery replacement manipulator of the space-time electric car has a high degree of automation, it has limited space for moving up and down, left and right, and is large in size. The movement is inflexible, and the smaller battery pack cannot be disassembled and assembled in a small space, and it is difficult to complete the disassembly and assembly of the battery

NIO’s battery-swapping manipulator is manually operated, with flexible movements and a large moving space, but the battery grip is too large. If the battery is arranged in the front cabin or under the rear seat cushion, it is difficult for the battery-swapping manipulator to fit in the front cabin, Operate in such a small space as the passenger compartment
