In an embodiment, when the support frame 1 is placed on the upper bracket 5, the four corners of the support frame 1 are contacted with the four ball heads of the upper bracket 5 and press the ball heads against the elastic force of the elastic member 66, so that the ball heads can be always abutted with the four corners of the support frame 1 under the support of the elastic member 66, so as to realize fine adjustment of the angle of the support frame 1 on the upper bracket 5 (i.e. when the support frame 1 is placed, if the support frame 1 is inclined to one side, the elastic support member 1 on the inclined side can support the support frame 1, so that the elastic support member 6 keeps the support frame 1 in a horizontal state as much as possible), and the gap between the support frame 1 and the upper bracket 5 is adaptively compensated. Preferably, the elastic member 66 is a compression spring.
Compared with the prior art, the vehicle battery pack battery replacement trolley with the self-adaptive position has the following advantages:
the invention drives the upper bracket 5 to move along the first direction on the lower bracket 7 through the first driving mechanism so as to drive the battery pack on the upper bracket 5 to synchronously move along the first direction. The second driving mechanism drives the lower bracket 7 to move on the main frame 8 along the second direction so as to drive the upper bracket 5 on the lower bracket 7 and the battery pack on the upper bracket 5 to move along the second direction. The third driving mechanism drives the main frame 8 to move in a third direction, so that the main frame 8 drives the lower support 7, the upper support 5 and the battery pack on the upper support 5 to move in the third direction, and the battery pack can be regulated in the X, Z, Y directions to be taken and put, so that the automatic replacement of the battery pack of the new energy vehicle is realized.
Under the drive of the first servo motor 22, when the swing arm 23 rotates to a vertical state, the guide wheel 24 is positioned in the locking groove 1011, the locking mechanism is locked with the battery pack 10, and the telescopic fork 3 can pull the battery pack 10 to move along the Y-axis direction; when the swing arm 23 is turned to the horizontal state, the guide pulley 24 is away from the lock groove 1011, and the lock mechanism is unlocked from the battery pack 10. Therefore, the quick locking or unlocking of the support frame 1 and the battery pack 10 can be realized quickly, manual operation is not needed, and the automatic design is realized, so that the taking and putting efficiency of the battery pack is greatly improved.
Under the support of the elastic member 66, the ball head is always abutted against the four corners of the support frame 1, so as to achieve fine adjustment of the angle of the support frame 1 on the upper bracket 5 (i.e. when the support frame 1 is placed, if the support frame 1 is inclined to one side, the elastic support member 1 on the inclined side supports the support frame 1, so that the elastic support member 6 keeps the support frame 1 in a horizontal state as much as possible), and adaptively compensates the gap between the support frame 1 and the upper bracket 5.
When the vehicle is required to be positioned, the positioning pin 11 moves along with the support frame 1 and is inserted into the positioning hole of the vehicle, so that the quick positioning connection between the battery changing trolley and the vehicle can be realized.
When it is desired to unlock the battery pack 10 from the vehicle in order to remove the battery pack, the driving member drives the push plate 44 to move in the Y-axis direction on the guide rail 43, so that the push pins 45 on the push plate 44 push the locking member (not shown) on the vehicle to quickly unlock the battery pack 10.
The foregoing descriptions of specific exemplary embodiments of the present invention are presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application to thereby enable one skilled in the art to make and utilize the invention in various exemplary embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
