Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping technology, and in particular to an automatic lifting and battery installation structure for heavy-duty trucks. Background Technology

[0002] The heavy-duty truck frame is the core support structure of a heavy-duty truck, equivalent to the vehicle's "skeleton." It is mainly used to carry cargo, power system, chassis components, and body, while ensuring the vehicle's strength, rigidity, and stability under various working conditions. Battery installation in the heavy-duty truck frame is a key link in new energy heavy-duty trucks (such as pure electric and hybrid models). Electric heavy-duty trucks and electric loaders can reduce a large amount of crude oil consumption and reduce pollutant emissions. The existing battery installation methods for heavy-duty truck frames mostly rely on traditional manual lifting of the truck frame (such as using jacks) to raise the frame to a suitable height, and then installing the battery in the pre-reserved position on the frame. This method is highly dependent on manual operation and has hidden dangers such as insufficient lifting force, unstable support, and misoperation, which affect the efficiency of battery installation, thereby affecting the processing progress of the equipment and increasing human resource investment. Therefore, we need to upgrade and modify the existing technology to overcome its problems and shortcomings. Summary of the Invention

Two sets of wheel parking V-shaped seats 37 are symmetrically arranged. The two sets of wheel parking V-shaped seats 37 are inclined at a certain angle. Anti-slip grooves are provided on the wheel parking V-shaped seats 37. By setting the wheel parking V-shaped seats 37, the wheels to be placed can be limited and supported, ensuring... To ensure the safety and stability of the vehicle's wheels when parked, a rack 56 is installed below the gear 57. The gear 57 and rack 56 mesh with each other, increasing the connectivity and intimacy between the devices, making it easier for users to control and use the devices, and providing convenience for users. An electric rotary table 611 is installed on the fixed rod frame 61. The electric rotary table 611 is fixedly connected to the telescopic fork 62, which can rotate and adjust the device according to usage needs, increasing the practicality and flexibility of the device, and providing convenience for users. Multiple unlocking guns 65 are provided. The unlocking guns 65 are located below the camera 64. By setting the unlocking guns 65, the battery can be unlocked, providing convenience for users.

[0023] The operating principle and process of this invention are as follows: First, the AGV drives the vehicle frame to the designated location. Then, the heavy-duty electric cylinder 26 and chain 261 are controlled to lift the fixed frame 28. As the fixed frame 28 is lifted, it slides on the sliding rod 27. Simultaneously, the lifting of the fixed frame 28 causes the wheel parking V-shaped seat 37 to rise together until it reaches the appropriate height. Then, the heavy-duty electric cylinder 45 and chain 46 are controlled to lift the fixed frame 48. As the fixed frame 48 is lifted, it slides on the sliding rod 27. 47 slides upwards, and at the same time, when the fixed frame 48 is lifted, it drives the wheel suspension 49 to rise until the wheel suspension 49 is raised to a suitable height. Then, the travel motor 55 is controlled to run, and the travel motor 55 drives the gear 57 to rotate. When the gear 57 rotates, it meshes with the gear 57. During the meshing process, it drives the connecting frame 54 and the slide 53 to move on the track 52. When the connecting frame 54 moves, it drives the RGV unlocking system 6 to move. After moving to a suitable position, the telescopic fork 62 is controlled to run. The telescopic fork 62 carries the RGV to the vehicle. At the bottom of the frame, the camera 64 on the RGV is controlled to operate. The camera 64 determines the position of the battery. Once the position is determined, the battery is assembled or unlocked by the unlocking gun 65. This enables automatic lifting and battery installation (i.e., automated battery swapping technology) for heavy-duty vehicles such as heavy trucks, shortening the battery swapping cycle, significantly improving battery swapping efficiency, reducing operating time costs, lowering labor costs and operational risks, centralizing battery maintenance, and extending the service life of the device. When the device needs to adjust the spacing according to the wheels during use, the servo motor 32 is controlled to operate. The servo motor 32 drives the bidirectional lead screw 33 to operate. The bidirectional lead screw 33 drives the connecting seat 36 to move horizontally on the bidirectional lead screw 33. When the connecting seat 36 moves, it drives the wheel parking V-shaped seat 37 to move until the wheel parking V-shaped seat 37 moves to the appropriate spacing. This allows for spacing adjustment of the device's lifting frame according to the wheels, making it compatible with multiple vehicle models, improving equipment versatility, reducing the risk of off-center loading, improving lifting stability, reducing tire and wheel hub damage, and meeting diverse needs.
