Problems solved by technology
Electric vehicle batteries take a long time to charge, which is not conducive to users' travel. If the fully charged battery can be quickly replaced, the problem of rapid power replenishment can be solved
However, at present, the battery pack is generally arranged under the chassis of the vehicle body, and the battery pack is fixed by multiple bolts or nuts. When replacing the battery pack, it is necessary to twist the bolts or nuts many times, which is not convenient for quick replacement of the battery pack.

The invention relates to a portable battery-changing electric vehicle battery pack quick-changing fixing structure which mainly comprises a plurality of clamping parts and a matching part, wherein the clamping parts are arranged on a vehicle body at intervals, each clamping part comprises a clamping cylinder fixedly arranged on the vehicle body and two clamping blocks oppositely arranged in the clamping cylinder, the two clamping blocks are connected through an elastic piece, and a passing part is defined between the two clamping blocks. The matching parts and the clamping parts are arranged on the battery pack in a one-to-one correspondence mode, each matching part comprises an annular fixing cylinder and an ejector rod arranged on the fixing cylinder, the ejector rods can be inserted into the passing parts and extrude the two clamping blocks to enable the two clamping blocks to be far away from each other, and clamping holes allowing the clamping blocks in the stretching-out state to be inserted are formed in the fixing cylinders. By arranging the two clamping blocks connected through the elastic piece and the ejector rod capable of pushing the two clamping blocks to be far away from each other, the clamping blocks can be clamped into the clamping holes of the fixing cylinder, so that connection between the battery pack and the vehicle body can be realized, and quick changing of the battery pack is facilitated.
Description
technical field [0001] The invention relates to the technical field of fast changing and fixing of battery packs of electric vehicles, in particular to a quick changing and fixing structure of battery packs of portable electric vehicles. Background technique [0002] Electric vehicles are powered by on-board power supplies, driven by motors to drive wheels, and meet the requirements of road traffic safety regulations. With the promotion of new energy vehicles, the problem of electric energy supplement for electric vehicles has become a bottleneck restricting its development. The charging time of electric vehicle batteries is long, which is not conducive to users' travel. If the fully charged batteries can be replaced quickly, the problem of rapid power replenishment can be solved. However, at present, the battery pack is generally arranged under the chassis of the vehicle body, and the battery pack is fixed by multiple bolts or nuts. When replacing the battery pack, it is n...
