At present, the main power conversion forms are as follows: as shown in figure 1, the device mainly comprises an RGV moving trolley 101, a lifting platform 102, a positioning and conveying platform 103, a vehicle-mounted battery frame 104, a battery 105, a universal ball 106, an electromagnet 107, an electric roller 108, a frame lock 109, a battery pack fixing boss 110 and an error adjuster 111.
The specific assembly steps are as follows: 1. the elevating platform 102 is fixed to the RGV moving car 101. 2. The positioning transport platform 103 is fixed to the elevating platform 102 integrally with the RGV moving car 101. 3. The battery is pushed into the positioning and conveying platform 103 from the direction A, and is conveyed to a fixed position by the electric roller 108, the positioning pin and the electromagnet 107 for positioning. 4. The battery 105 is rapidly moved to the position of the frame lock 109 by the RGV moving trolley 101 (the frame lock 109 is the installation of the vehicle body battery pack, and belongs to the electric vehicle body and belongs to the fixing part). 5. The lifting platform 102 is lifted to enable the battery to approach the frame lock 109, and after the battery is subjected to 1 cm quick fine adjustment through the error adjuster 111 arranged on the periphery of the positioning and conveying platform 103, the battery is pushed into the frame lock 109. The correct installation of the battery can be completed. 6. After lowering the lifting platform 102 to the initial height, the RGV moving trolley 101 is used to hear the pre-fixed position or repeat the above steps for the next assembly.
The concrete disassembly steps are as follows: 1. the positioning and conveying platform 103 is fixed to the lifting platform 102 and the RGV moving trolley 101 to form a whole, moves below the frame lock 109, continuously rises, and pushes the frame lock 109 after being subjected to 1 cm quick fine adjustment through the error adjuster 111 on the periphery of the positioning and conveying platform 103. 2. The structure of fig. 3 is formed after the jacking is completed. 3. At the moment, the electromagnet 107 starts to work and is ejected along the direction B, meanwhile, the frame lock catch 109 is forced to move towards the direction C by the force in the direction B, and when the ejecting force in the direction B reaches the maximum, the extending component of the electromagnet replaces the position of the frame lock catch 109, so that the unlocking purpose is realized. The battery can be easily removed by lowering the height of the lifting platform 102. When the battery leaves the position of the frame catch 109, the frame catch 109 will snap out, ensuring the next battery installation.
The conventional locking device is limited by application scenarios, and has not strong reliability and high cost.
