Mounting and dismounting mechanism for electrombile battery and mounting and dismounting method thereof

Abstract

The invention discloses a mounting and dismounting mechanism for an electrombile battery and a mounting and dismounting method thereof. An automatic fast-replacing battery box system of the pure electrombile power battery comprises a battery outer box, a battery inner box and a battery mounting and dismounting mechanism, wherein the battery inner box is placed inside the battery outer box; the battery outer box adopts a frame structure; a guide rail is arranged in the middle of the bottom casing of the battery outer box; a sliding structure matched with the guide rail is correspondingly arranged at the bottom of the battery inner box; the battery mounting and dismounting mechanism comprises a straining cylinder and a linkage mechanism; the straining cylinder is fixedly connected with the frame on one side of the battery outer box; the end part of a straining piston rod of the straining cylinder is connected with the corresponding position at the bottom of the battery inner box through an electromagnet; the straining cylinder is connected with the cylinder control system through an air channel control electromagnetic valve, and supplies power through the straining cylinder; the battery inner box can move along the guide rail; and the linkage mechanism is fixedly arranged at the bottom casing of the battery outer box, and moves in response to the movement of the straining cylinder.

Description

technical field [0001] The invention relates to a loading and unloading mechanism and a loading and unloading method, in particular to a battery loading and unloading mechanism and a loading and unloading method of a pure electric vehicle power battery automatic quick-change battery box system. Background technique [0002] With the development of society, energy is increasingly scarce, environmental pollution is serious, and the potential impact of global climate change is huge. Electric vehicles with diversified power sources and zero emissions have become the development direction of future vehicles. In the past, the power energy of vehicles mainly came from petroleum products and various gases. However, with the decreasing of oil and gas resources and the increasingly serious problems of noise pollution, air pollution and global warming, it is necessary to develop and utilize environmentally friendly alternative energy sources, reduce CO2 Emissions have become the consen...

Problems solved by technology

However, there is a common problem in pure electric vehicles powered by rechargeable batteries. The charging time of ordinary vehicle batteries takes several hours, and they cannot quickly complete energy replenishment at gas stations like other oil and gas fuels, thus greatly limiting electric vehicles. the popularity of

[0003] In order to solve the above problems, the patent application No. 200810006771.6 proposes a method and device for quickly replacing large-scale battery packs. These methods generally use so-called high-voltage battery packs or full-voltage battery packs as replacement units to achieve rapid replacement of the entire battery pack. It is easy to install and unload, easy to maintain, expands the mileage, and is suitable for separate charging; but the invention does not realize automatic replacement, because most of the power batteries are lithium-ion polymer batteries, which have relatively high energy density and relatively large mass. Moreover, it belongs to the category of high-voltage electricity, and there is a certain danger in manual operation.

In addition, the existing quick-change system still needs a lot of manual inspection after the battery replacement is completed, and the reliability is not enough, so the battery replacement time is relatively long

[0004] In order to realize automatic replacement, the patent application No. 20111015101.9 discloses a quick battery replacement device for electric vehicles, which includes a track fixed on the ground and a frame slidingly connected with the track, a base is provided at the bottom of the frame, and a The pallet, the base and the pallet are provided with a lifting mechanism, and the battery positioning mechanism is also provided on the electric vehicle battery quick replacement device, including a correction arm and a pressure rod. This invention provides a compact, accurate positioning electric The quick and automatic battery replacement device for automobiles can save trouble and effort to complete the battery replacement work; however, the automatic replacement device is suitable for electric vehicles that load and unload batteries from the bottom of the vehicle, but not for electric vehicles that are loaded and unloaded from the side of the vehicle body, and the battery box is in the Passively accept replacement, the replacement efficiency is still low

[0005] In order to further improve the efficiency of replacing the battery box, the patent application number 20111009392.9 discloses a method for replacing the battery box and a battery replacement fixture, which uses the battery replacement fixture to carry the battery box, and the battery replacement fixture is installed on a movable quick-change system , the quick-change system completes the transfer of the battery box; the battery box is pulled out from the electric vehicle or charging rack through the rodless cylinder, and the battery box is pushed from the battery changing fixture into the electric vehicle or charging rack; the battery changing fixture Open or lock the battery box by unlocking the cylinder; complete the process of replacing the battery box; but the above-mentioned clamps directly act on the battery box during the battery box replacement process, because it is difficult to standardize the specifications and models of the battery objectively. Especially when clamping, it is easy to be unstable or unable to clamp, which cannot meet the needs of electric energy supplementary mechanisms similar to gas stations; and the battery box is passively accepted for replacement, and there is still a need for automatic replacement. with a certain gap
