The utility model discloses a still another preferred embodiment provides an electric automobile, include: the quick-change power battery mounting system is described above.

The utility model discloses an electric automobile that provides in a concrete embodiment, include as above quick change power battery mounting system, can realize the efficient change of quick change power battery package through above-mentioned quick change power battery mounting system, be favorable to avoiding the difficult problem of charging because of the facility imperfectly leads to of charging at present to and change quick change power battery package operation complicacy, consuming time longer problem at present.

In a specific embodiment of the present invention, when the quick-change power battery mounting system is used to mount a quick-change power battery pack, in order to ensure that the locking mechanism body can insert the locking portion of the quick-change battery pack, the quick-change power battery mounting system needs to be unlocked by the secondary locking mechanism, so that the sheet metal connector can move along the first direction, specifically, the secondary locking mechanism is controlled to pivot to the unlocking position, so that the secondary locking mechanism is separated from the sheet metal connector, and the secondary locking mechanism is prevented from preventing the connecting member from moving along the first direction; the quick-change power battery pack and the locking mechanism body are controlled to move relatively, the locking part is inserted into the locking mechanism body for installation, and the process of specifically controlling the quick-change power battery pack and the locking mechanism body to move relatively can be realized by enabling the quick-change power battery pack to ascend from the lower part of the electric automobile; or the electric automobile is firstly ascended, and the quick-change battery pack to be replaced is positioned at the bottom of the automobile, so that the electric automobile is descended. Specifically, when the locking part is inserted into the locking mechanism body, the locking part can push the ratchet wheel of the locking mechanism body, so that the ratchet wheel rotates around the ratchet wheel shaft and drives the pawl to rotate around the pawl shaft. At the moment, the ratchet wheel is in contact with the microswitch, so that the microswitch is triggered to be closed, and when the microswitch is detected to be closed, the locking mechanism body and the locking part can be locked; or, when the sensor detects that the ratchet wheel rotates to the preset fixed position, the locking mechanism body and the locking part can be determined to be locked. And then in order to guarantee the stability of power battery package installation, still need control secondary locking mechanism and resume to the locking position, carry out the secondary locking. When the quick-change power battery pack is installed by adopting the method, automatic locking can be realized only by enabling the quick-change power battery pack provided with the locking part to move relative to the electric automobile, the operation is simple, the installation efficiency of the quick-change power battery pack is improved, and the replacement efficiency of the quick-change power battery pack is further improved.

In a specific embodiment of the present invention, when the quick-change power battery pack installed in the quick-change power battery installation system is disassembled, the secondary locking mechanism is controlled to pivot from the locking position to the unlocking position, so that the sheet metal connector is no longer blocked by the secondary locking mechanism in the first direction; and the sheet metal connecting piece is driven to slide along the first direction, so that the sheet metal connecting piece further drives the locking mechanism bodies to be linked and unlocked. After the locking mechanism body is unlocked, the pawl and the ratchet wheel are in a non-clamping state, and the ratchet wheel has a tendency of switching to a state when the locking part is not inserted under the action of gravity of the quick-change power battery pack or elastic force of the ratchet wheel resetting structure, so that the quick-change power battery pack can be separated from the locking mechanism body, and the unlocking of the quick-change power battery pack is indicated; optionally, when the micro switch is detected to be switched to the non-closed state from the triggered closed state, or when the ratchet wheel sent by the sensor is received to rotate away from the preset fixed position, the fact that the quick-change power battery pack is unlocked can be accurately determined; when the method is adopted to disassemble the quick-change power battery pack, the operation is simple, the disassembling efficiency of the quick-change power battery pack is improved, and the improvement of the replacing efficiency of the quick-change power battery pack is further facilitated.
