Description

Technical Field

[0001] This utility model relates to the field of quick-change power battery technology, specifically a quick-change locking module for quick-change power batteries. Background Technology

[0002] Range anxiety has led to the rapid development of fast-swap technology for electric vehicle power batteries. Currently, the fast-swap structure on the market is mainly bolt-type fast-swap.

[0003] The principle of bolt-type quick-switch is to connect the battery pack to the chassis with bolts. Battery pack replacement will cause severe wear on the bolts and chassis nuts, making it impossible to effectively connect and maintain torque. Generally, car manufacturers require that the power battery quick-switch structure can meet 10,000 battery pack replacements. Currently, bolt-type quick-switch can only meet 1,500 to 3,000 battery pack replacements. The wear on the bolts and chassis nuts is unacceptable. In addition, the battery swapping platform needs to tighten dozens of bolts at the same time, resulting in a long battery swapping time. To address this, we have proposed a quick-switch locking module for power batteries. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change locking module for quick-change power batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-change locking module for a power battery includes a power battery body and fixing blocks. Fixing blocks are fixedly installed at the four corners of the power battery body. Each fixing block has an installation opening at its top, and a through hole at its top. One end of the through hole is semi-circular, and the other end is rectangular. A slot, which is semi-circular and communicates with the through hole, is formed on the inner wall of the installation opening. A sealing gasket, made of rubber, is fixedly installed on the top of the fixing blocks and located around the installation opening. A locking post is installed inside the installation opening, and a locking block is fixedly installed on one side of the locking post, engaging with the slot. A pressure plate is fixedly installed on the top of the locking post.

[0007] The bottom of the pressure plate is in contact with the sealing gasket, and a push rod is fixedly installed on the top of the pressure plate. An electric push rod is installed on the top of the push rod.

[0008] The top of the electric push rod is rotatably connected to a fixing plate, and a servo motor is fixedly mounted on the top of the fixing plate.

[0009] The output end of the servo motor is fixedly connected to the top of the electric push rod, and connecting plates are fixedly installed at both ends of the top of the fixed plate.

[0010] The connecting plate is fixedly installed at the bottom of the vehicle, and a nameplate with information is fixedly installed at the front of the power battery body.

[0011] The power battery body has a display screen fixedly installed on one side, a display screen fixedly installed on one side of the display screen, and an indicator light installed on one side of the display screen.

[0012] The servo motor is electrically connected to the in-vehicle control device, and the electric push rod is electrically connected to the in-vehicle control device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This quick-change locking module for a power battery allows for rapid battery replacement. After the power battery body is placed in position, the vehicle control device sends a command to activate the electric push rod. The electric push rod extends, causing the push rod, locking pin, and locking block to move downwards along the rectangular through hole of the mounting opening until the locking block enters the mounting opening. Subsequently, the servo motor starts, driving the electric push rod and locking pin to rotate, causing the locking block to rotate with the locking pin until it aligns with the semi-circular annular groove and engages in the groove. At the same time, the electric push rod applies further pressure, causing the bottom of the pressure plate to tightly adhere to the sealing gasket. The deformation of the rubber sealing gasket achieves a seal and protection of the mounting opening, completing the secure locking of the power battery. Compared with traditional bolt fastening, this device achieves a faster fixing speed.

[0015] 2. This quick-change locking module for power batteries operates as follows: During unlocking, the in-vehicle control device first controls a servo motor to rotate in the opposite direction, causing the locking pin and locking block to rotate and disengage from the slot, aligning the locking block with the rectangular segment of the through hole. Then, the electric push rod retracts, pulling the locking pin and locking block upwards along the rectangular through hole until the locking block is completely disengaged from the mounting opening. At this point, the locking constraint on the power battery body is released, enabling quick disassembly and replacement. Throughout the process, the movement precision of the servo motor and electric push rod is precisely controlled by the in-vehicle control device, ensuring efficient and stable locking and unlocking. Compared to traditional bolt disassembly, this device offers higher disassembly efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0023] A quick-change locking module for a power battery includes a power battery body 1 and fixing blocks 2. Fixing blocks 2 are fixedly installed at the four corners of the power battery body 1. The top of the fixing blocks 2 has an installation port 3. The top of the installation port 3 has a through hole 4. One end of the through hole 4 is semi-circular and the other end is rectangular. The inner wall of the installation port 3 has a slot 5. The slot 5 is semi-circular and communicates with the through hole 4. A sealing gasket 6 is fixedly installed on the top of the fixing blocks 2. The sealing gasket 6 is located on the periphery of the installation port 3 and is made of rubber. A locking post 7 is installed inside the installation port 3. A locking block 8 is fixedly installed on one side of the locking post 7. The locking block 8 and the slot 5 are locked together. A pressure plate 9 is fixedly installed on the top of the locking post 7.

[0024] The pressure plate 9 is fitted to the bottom of the sealing gasket 6. A push rod 10 is fixedly installed on the top of the pressure plate 9. An electric push rod 11 is installed on the top of the push rod 10. A fixing plate 12 is rotatably connected to the top of the electric push rod 11. A servo motor 13 is fixedly installed on the top of the fixing plate 12. The output end of the servo motor 13 is fixedly connected to the top of the electric push rod 11. Connecting plates 14 are fixedly installed at both ends of the top of the fixing plate 12. The connecting plates 14 are fixedly installed at the bottom of the vehicle. A nameplate information 15 is fixedly installed on the front of the power battery body 1. A display 16 is fixedly installed on one side of the power battery body 1. A display screen 17 is fixedly installed on one side of the display 16. An indicator light 18 is installed on one side of the display 16. The servo motor 13 is electrically connected to the in-vehicle control device. The electric push rod 11 is electrically connected to the in-vehicle control device.

[0025] Through the above scheme, the module achieves mechanical fixation and sealing protection through the linkage of the electric push rod 11 and the servo motor 13. The electric push rod 11 drives the push rod 10 to move the locking pin 7 down along the rectangular through hole 4, so that the locking block 8 enters the installation port 3; the servo motor 13 then drives the locking pin 7 to rotate, so that the locking block 8 is precisely engaged with the semi-circular annular groove 5, forming a stable mechanical locking structure. At the same time, the electric push rod 11 continuously applies pressure, causing the pressure plate 9 to fit tightly against the rubber sealing gasket 6. The deformation of the sealing gasket 6 achieves dustproof and waterproof sealing of the installation port 3, while the fixing plate 12 and the connecting plate 14 stably fix the driving component to the bottom of the car, ensuring the structural stability of the locking process. In the unlocking stage, the module achieves constraint release and safe disengagement through reverse operation. The in-vehicle control device controls the servo motor 13 to rotate in the opposite direction, causing the locking block 8 to disengage from the groove 5 and align with the rectangular through hole 4; then the electric push rod 11 retracts, and the push rod 10 pulls the locking pin 7 up, so that the locking block 8 completely disengages from the installation port 3, releasing the locking constraint of the power battery. During the process, the display screen 17 and indicator lights 18 of the display 16 provide real-time feedback on status information, and the nameplate information 15 provides parameter basis for the replacement operation. The entire process is precisely controlled by the in-vehicle control device to achieve rapid unlocking and efficient replacement of the power battery.

[0026] In this embodiment, a quick-change locking module for a power battery operates as follows: First, after the power battery body 1 is placed in position, the vehicle control device sends a command to activate the electric push rod 11. The electric push rod 11 extends, causing the push rod 10, the locking pin 7, and the locking block 8 to move downwards along the rectangular through hole 4 of the mounting opening 3 of the fixing block 2 until the locking block 8 enters the mounting opening 3. Subsequently, the servo motor 13 starts, driving the electric push rod 11 and the locking pin 7 to rotate, causing the locking block 8 to rotate with the locking pin 7 until it aligns with the semi-circular annular groove 5 and locks into the groove 5. At the same time, the electric push rod 11 further applies pressure, causing the bottom of the pressure plate 9 to tightly adhere to the sealing gasket 6. The deformation of the rubber sealing gasket 6 achieves sealing protection of the mounting opening 3, completing the secure locking of the power battery. Through the above design, compared with traditional bolt fastening, this device has a faster fixing speed. Then, during the unlocking operation, the vehicle control device first controls the servo motor 13 to rotate in the opposite direction, causing the locking pin 7 and the locking block 8 to rotate and disengage from the groove 5, aligning the locking block 8 with the rectangular segment of the through hole 4. Then, the electric push rod 11 retracts, pulling the locking pin 7 and locking block 8 upwards along the rectangular through hole 4 via the push rod 10, until the locking block 8 is completely disengaged from the mounting port 3. At this point, the locking constraint of the power battery body 1 is released, allowing for quick disassembly and replacement. Throughout the process, the movement accuracy of the servo motor 13 and the electric push rod 11 is precisely controlled by the in-vehicle control device, ensuring efficient and stable locking and unlocking. Compared to traditional bolt disassembly, this device offers higher disassembly efficiency.
