Description

Technical Field

[0001] The present invention relates to the technical field of light truck battery replacement, and in particular to a light truck battery replacement station and a battery replacement method. Background Art

[0002] Light trucks refer to N2-type trucks with a maximum design gross weight of no more than 4.5 tons in the N-type truck classification. With the development of the times, light trucks have evolved into new energy light trucks, and new energy light trucks need to be replaced with batteries.

[0003] Chinese patent application No. 2023227680376 discloses a new energy light truck intelligent battery swap station, including a battery swap platform, a battery compartment, two visual recognition machines, a stacker and an operating room; wherein: the battery swap platform is used to park vehicles; the battery compartment is used to store and charge battery boxes; the two visual recognition machines respectively identify the body shape of the vehicle and the battery box, and transmit the corresponding data to the operating room; the stacker is used to disassemble and assemble the battery box, which includes a mounting frame, four lifting parts, a battery rack, a Y-axis rail and a locking and unlocking part; the Y-axis rail is laid on the ground and one end of which is located in the battery swap platform, and the mounting frame is moved and installed along the Y-axis rail.

[0004] However, the above-mentioned battery swap stations have the following problems during operation:

[0005] 1. The Y-track of the battery swap station is laid on the ground and one end is located in the battery swap platform. When swapping batteries for light trucks, it is necessary to drive the locking and unlocking parts to move to the bottom of the new energy light truck to lock and unlock the battery. However, the space between the bottom of the light truck and the ground is relatively narrow. If the battery of the light truck is large, it is difficult to lock and unlock the battery.

[0006] 2. The battery swap station is equipped with a battery compartment and a charging room, but the specific internal structure of the battery compartment and the charging room is not recorded in detail, nor is it explained how the batteries are stored and charged in the battery compartment and the charging room. If manual operation is required for storage and charging, the operating efficiency of the battery swap station will be greatly reduced. Summary of the invention

[0026] The beneficial effects of the present invention are:

[0027] (1) The present invention unlocks and removes the battery bolts at the bottom of the light truck through a transport unlocking mechanism, transports the battery to a storage mechanism for charging through a stacking mechanism, transports the fully charged battery on the carrier to the transport unlocking mechanism through the stacking mechanism, and locks the battery at the bottom of the light truck through the transport unlocking mechanism to complete the installation of the battery. The battery replacement of the light truck is completed through automation, which improves the battery replacement efficiency compared to manual operation. By setting a groove in the ground plane, the closing component is driven to open the space at the bottom of the light truck, thereby increasing the unlocking and locking space at the bottom of the light truck, making it easier for the transport unlocking mechanism to remove and install the battery from the light truck.

[0028] (2) The present invention drives the second gear to rotate through the seventh rotating drive member. Since the second gear is meshed with the second rack plate, the third moving plate is driven to move on the seventh guide rail, and the ejection and disassembly assembly is driven to move to the bottom of the light truck. The lifting assembly drives the ejection and disassembly assembly to move upward until the sleeve rod contacts the battery bolts at the bottom of the light truck. The ninth rotating drive member drives the sleeve rod to rotate to unlock and disassemble the battery bolts at the bottom of the light truck; the battery falls on the ejection and disassembly assembly, specifically, on the support rod located on the fourth moving plate.

[0029] (3) The present invention drives the third gear to rotate through the sixth rotating drive member, drives the second moving frame to move on the third guide rail, and drives the batteries on the pallet to move synchronously. The eighth rotating drive member drives the sprocket to rotate, drives the lifting frame to rise or fall, and drives the batteries on the pallet to move synchronously until it moves to the top of the storage rack; the sixth linear drive member drives the pallet to move, places the batteries on the carrier, and stacks and stores the batteries.

[0030] (4) The present invention uses a stacking mechanism to transport the battery to a bearing plate in a fire extinguishing box. The seventh linear drive member drives the bearing plate to move downward until the insulating coolant submerges the battery to cool it down and extinguish the fire. The insulating coolant in the fire extinguishing box is pumped to the top of the third conical block through the first pipe by a water pump. The insulating coolant flows downward along the conical surfaces of the third conical block, the second conical block, and the first conical block. A fan is provided on the top of the cooling box to enhance the flow of air. The insulating coolant is spread evenly on the conical surfaces of the third conical block, the second conical block, and the first conical block and flows downward, thereby accelerating the cooling of the insulating coolant.

[0031] (5) The present invention drives the third conical block to move upward through the tenth linear drive member, and the limit slider slides in the slide groove to drag the second conical block to move upward. There is a gap between the third conical block and the second conical block, and there is a gap between the first conical block and the second conical block. In the process of the insulating coolant flowing downward on the conical surfaces of the third conical block, the second conical block, and the first conical block, the contact time between the insulating coolant and the air is extended, thereby enhancing the cooling of the insulating coolant.

The eighth rotary drive member 410 drives the sprocket 408 to rotate, drives the lifting frame 411 to rise or fall, and drives the batteries on the pallet 418 to move synchronously until they move to the front of the storage rack 501. The sixth linear drive member 417 drives the pallet 418 to move, puts the batteries on the carrier 502, and stacks and stores the batteries.

[0101] Step 5, charging process: the third linear drive member 506 drives the third moving frame 505 to move downward, drives the charging plug 507 to move downward and insert into the charging interface of the battery, and charges the battery on the carrier 502;

[0102] Step 6, locking process: the fully charged battery on the carrier 502 is transported to the transport unlocking mechanism 3 through the stacking mechanism 4, and the transport unlocking mechanism 3 locks the battery at the bottom of the light truck to complete the installation of the battery;

[0103] Step 7, fire fighting process: When the temperature sensor on the storage rack 501 detects that the temperature of the battery is too high or the camera detects that the battery has smoke or sparks, the stacking mechanism 4 moves the battery to the bearing plate 603 in the fire fighting box 601, and the seventh linear drive member 602 drives the bearing plate 603 to move downward until the insulating coolant submerges the battery to cool it down and extinguish the fire;

[0104] Step 8, cooling process: the insulating coolant in the fire fighting box 601 is pumped to the top of the third conical block 608 through the first pipe 610 by a water pump, and the insulating coolant flows downward along the conical surfaces of the third conical block 608, the second conical block 607, and the first conical block 606. A fan is arranged on the top of the cooling box 604 to enhance the flow of air, and the insulating coolant is spread on the conical surfaces of the third conical block 608, the second conical block 607, and the first conical block 606 and flows downward, thereby accelerating the cooling of the insulating coolant;

[0105] Step nine, enhancement process: the tenth linear drive member 609 drives the third conical block 608 to move upward, the limiting slider 611 slides in the sliding groove 600, and drags the second conical block 607 to move upward. There is a gap between the third conical block 608 and the second conical block 607, and there is a gap between the first conical block 606 and the second conical block 607. The insulating coolant is spread on the conical surfaces of the third conical block 608, the second conical block 607, and the first conical block 606. In the process of flowing downward, the contact time between the insulating coolant and the air is extended, thereby enhancing the cooling of the insulating coolant.
