[0002] With the development of new energy technologies and environmental protection requirements, more and more commercial vehicles (such as trucks, logistics vehicles, freight trucks, etc.) use electric motors to replace conventional gasoline or diesel engines to drive the vehicles. Different from household new energy vehicles, commercial vehicles often adopt the form of battery swapping to solve the range anxiety, so as to quickly replenish electric energy and improve transportation efficiency; However, at present, the structure and functions of battery swapping vehicles are too simple, and the degree of automation is low. It is impossible to automatically detect the battery power inside the vehicle. When the battery power inside the vehicle is exhausted, the staff needs to manually push the battery swapping vehicle to the vicinity of the vehicle to perform the battery swapping operation on the vehicle, which results in low efficiency of the staff using the battery swapping vehicle to swap the battery for the vehicle; To solve the above problems, a battery state detection device and a control method thereof are proposed in this application. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solutions: A battery state detection device includes a base. A lifting component is installed on the top of the base. A lifting plate is connected to the top of the lifting component. A storage battery is fixedly installed on one side of the top of the base where the lifting component is located. One end of the top of the lifting plate is fixedly connected to a fixing plate. Symmetrical first electric telescopic rods are fixedly installed on both sides of the top of the lifting plate. The upper end of the first electric telescopic rod is fixedly connected to a placement plate. A robotic arm is fixedly installed on the side of the lifting plate away from the fixing plate. A clamping component is fixedly connected to the end of the robotic arm away from the lifting plate. A controller is fixedly installed on one side of the fixing plate. A battery state sensor for detecting the battery state is fixedly installed on the top of the fixing plate. A vision sensor for positioning is fixedly installed on one side of the battery state sensor on the top of the fixing plate. A cleaning component for cleaning the battery state sensor and the vision sensor is arranged on the top of the fixing plate.

[0005] Working Principle and Beneficial Effects of the Present Invention: Working principle: When the battery replacement vehicle is in use, the storage battery can supply power to the electronic components on the battery replacement vehicle. All the electronic components on the battery replacement vehicle are electrically connected to the controller. By controlling the operation of the lifting component by the controller, the height of the lifting plate can be adjusted. The height of the placement plate can be further adjusted by the first electric telescopic rod. When the battery power inside the vehicle is low, an electrical signal will be sent to the battery status sensor, and the battery status sensor will send an electrical signal to the controller. The controller can control the movement of the battery replacement vehicle. The battery replacement vehicle can be positioned by the vision sensor, so as to control the battery replacement vehicle to move to the designated position. The controller controls the robotic arm and the clamping component to remove the battery inside the vehicle and place it on the placement plate, and finally controls the robotic arm to install the new battery on the battery replacement vehicle into the vehicle, thus completing the battery replacement. The cleaning component arranged on the fixing plate can regularly clean the battery status sensor and the vision sensor, so as to ensure the normal operation of the device. Beneficial effects

[0006] (1) Through the lifting component arranged between the base and the lifting plate, the height of the lifting plate can be adjusted. The height of the placement plate can be adjusted by the first electric telescopic rod. This enables the battery replacement vehicle to perform battery replacement operations for different vehicle models, thus making the battery replacement vehicle more practical. (2) Through the battery status sensor and the vision sensor arranged on the top of the fixing plate, when the battery power inside the vehicle is low, an electrical signal will be sent to the battery status sensor, and the battery status sensor can send an electrical signal to the controller, thereby controlling the movement of the battery replacement vehicle. The vision sensor can play a good positioning role for the battery replacement vehicle, making the battery replacement vehicle more automated, and thus effectively improving the battery replacement efficiency of the battery replacement vehicle. (3) Through the cleaning component arranged on the top of the fixing plate, the battery status sensor and the vision sensor can be regularly cleaned, which can effectively prevent excessive dust from adhering to the battery status sensor and the vision sensor and affecting the normal operation of the device.

[0007] Preferably, the lifting component includes cross lifting rods connected to the top of the base, and the cross lifting rods are symmetrically arranged on the top of the base. One end of the bottom of the cross lifting rod is slidably and rotatably connected to the base, and the other end is rotatably connected to the base. One end of the top of the cross lifting rod is slidably and rotatably connected to the lifting plate, and the other end is rotatably connected to the lifting plate. A hydraulic rod is rotatably connected between the two groups of cross lifting rods on the top of the base. The upper end of the hydraulic rod is rotatably connected to the lifting plate. The storage battery can supply power to the hydraulic rod, and the controller can control the hydraulic rod to start. After starting the hydraulic rod, the height of the battery replacement vehicle can be adjusted through the cooperation of the cross lifting rods, thus effectively improving the practicality of the battery replacement vehicle.

[0008] Preferably, the clamping assembly includes a fixed box fixedly connected to one end of the robotic arm away from the lifting plate. Symmetrical T-shaped grooves are formed on one side of the fixed box away from the robotic arm. T-shaped blocks are slidably connected to the inside of the T-shaped grooves. One side of the T-shaped block extends out of the T-shaped groove and is fixedly connected to a clamping block. One end of the fixed box is fixedly connected to a driving assembly for synchronously moving the two clamping blocks. After the battery swapping vehicle moves to the designated position, the controller controls the robotic arm to bring the fixed box close to the vehicle's internal battery, and then controls the driving assembly to operate. By the operation of the driving assembly, the two T-shaped blocks can drive the clamping blocks to move simultaneously in the approaching direction, thereby clamping the battery. Then, the battery can be disassembled by controlling the robotic arm. After the battery is disassembled, it is placed on the placement plate. Then, the new battery on the placement plate is clamped and fixed by the clamping assembly. Finally, the battery is installed into the battery installation slot in the vehicle by the robotic arm, and the battery replacement is completed.

[0009] Preferably, the cleaning assembly includes a fixed block fixedly connected to one end of the top of the fixed plate. A second electric telescopic rod is fixedly installed on one side of the fixed block. The end of the second electric telescopic rod away from the fixed block is fixedly connected to a water storage box. An inlet is formed on the top of the water storage box. A threaded cover is threadedly connected to the water storage box at the inlet. A micro pump is fixedly installed inside the water storage box. A spray head is fixedly connected to the bottom of the water storage box. The spray head is communicated with the inside of the water storage box, and the output end of the micro pump is fixedly connected to the spray head. A cleaning cotton is fixedly connected to the bottom of the water storage box on one side of the spray head. Cleaning liquid can be added to the inside of the water storage box through the inlet formed on the top of the water storage box. After the cleaning liquid is added, the threaded cover is installed at the inlet of the water storage box. The controller controls the operation of the second electric telescopic rod, which can move the water storage box on the fixed plate. At the same time, controlling the operation of the micro pump can spray the cleaning liquid inside the water storage box through the spray head. In this way, the battery status sensor and the vision sensor can be flushed. At the same time, the dust and water stains on the battery status sensor and the vision sensor can be wiped by the cleaning cotton provided at the bottom of the water storage box, thereby achieving a good cleaning effect on the battery status sensor and the vision sensor. This can effectively prevent excessive dust adhesion on the battery status sensor and the vision sensor from affecting the normal operation of the device.

[0010] Preferably, the driving assembly includes a driving box fixedly connected to one end of the fixed box. A servo motor is fixedly installed inside the driving box. Ventilation holes are formed on both sides of the driving box, and filter nets are fixedly connected to the inner walls of the ventilation holes. The output end of the servo motor is fixedly connected to a bidirectional lead screw. The other end of the bidirectional lead screw extends into the T-shaped groove and is rotatably connected to the inner wall of the T-shaped groove. The bidirectional lead screw passes through two T-shaped blocks, and the bidirectional lead screw and the T-shaped blocks are both threadedly connected. By controlling the servo motor to start through the controller, the bidirectional lead screw can be rotated by the operation of the servo motor. While the bidirectional lead screw rotates, the two T-shaped blocks threadedly connected to it can drive the clamping blocks to move synchronously, thereby realizing the clamping function of the battery, which can further improve the automation degree of the device.

[0011] Preferably, guide blocks are fixedly connected to both sides of the bottom of the water storage box. Guide grooves matching the guide blocks are formed on the top of the fixed plate. When the second electric telescopic rod drives the water storage box to move, through the guide blocks arranged at the bottom of the water storage box and the guide grooves formed at the bottom of the fixed plate, not only can a good supporting effect be exerted on the water storage box, but also a good limiting and guiding effect can be exerted on the water storage box, so that the water storage box has higher stability when moving.

[0012] Preferably, scraping strips are fixedly connected to both sides of the cleaning cotton, and the scraping strips are made of rubber material. Through the scraping strips arranged on both sides of the cleaning cotton, the cleaning liquid on the battery state sensor and the vision sensor can be scraped off, so that the cleaning cotton can achieve a better cleaning effect on the battery state sensor and the vision sensor. Since the texture of the rubber material is relatively soft, the scraping strips made of rubber material can have a good protective effect on the battery state sensor and the vision sensor.

[0013] Preferably, a plurality of balls are rotatably connected to the bottom of each guide block, and the balls are linearly arrayed and evenly distributed on the guide block. During the movement of the water storage box, the guide block will slide inside the guide groove. Through the plurality of balls arranged at the bottom of the guide block, the friction between the guide block and the inner wall of the guide groove can be effectively reduced. In this way, not only can the water storage box move more smoothly, but also the wear generated between the guide block and the fixed plate can be effectively reduced.

[0014] Preferably, rubber pads are fixedly connected to the opposite sides of the two clamping blocks, and anti-slip lines are formed on the rubber pads. Since the texture of the rubber material is relatively soft, through the rubber pads arranged on the opposite sides of the two clamping blocks, the hard contact between the battery and the clamping blocks can be effectively avoided, thereby having a good protective effect on the battery. Through the anti-slip lines formed on the rubber pads, the friction between the battery and the clamping blocks can be effectively reduced, so that the battery can be better fixed after being clamped by the two clamping blocks.

[0015] A control method for a battery state detection device of the present invention. When the battery power inside the vehicle is low, an electrical signal is sent to the battery state sensor on the battery swapping vehicle. Through the battery state sensor, an electrical signal can be sent to the controller. Through the controller, the battery swapping vehicle can be controlled to move. Through the vision sensor, the battery swapping vehicle can be positioned, so as to control the battery swapping vehicle to move to a specified position. The controller controls the robotic arm and the clamping assembly to remove the battery inside the vehicle and place it on the placement board. Finally, the controller controls the robotic arm to install a new battery on the battery swapping vehicle into the vehicle, that is, the battery replacement is completed.
