Description

Technical Field

[0001] The utility model relates to the technical field of light truck battery swapping equipment, in particular to a drag chain lifting avoidance and automatic reset device. Background Art

[0002] At present, with the rapid development of the new energy vehicle industry, the efficiency and safety in the battery swapping process have become the focus of the industry. In this process, as a key link, the battery unlocking and locking device requires the assistance of a lifting mechanism. The lifting mechanism is like the "arm" of the battery swapping operation, accurately performing each task of extracting and installing the battery. However, with the increasingly strict pursuit of space utilization rate by battery swapping equipment, how to achieve efficient and safe operation in a limited space has become a difficult problem.

[0003] The drag chain can accommodate and protect the cable inside, preventing it from being worn or broken during reciprocating motion. In the complex environment of the battery swapping equipment, the application of the drag chain not only effectively extends the service life of the cable but also greatly improves the overall reliability of the equipment. However, in actual applications, it is found that there is often an interference problem between the existing drag chain and the platform. This interference not only affects the smoothness of the battery swapping operation but also may cause unnecessary damage to the equipment.

[0004] Therefore, it is particularly important to develop a drag chain lifting avoidance and automatic reset device. Summary of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a drag chain lifting avoidance and automatic reset device, which effectively solves the interference problem between the drag chain and the platform, thereby significantly improving the overall operation efficiency and safety.

[0006] To solve the above technical problem, one technical solution adopted by the utility model is:

[0007] A drag chain lifting avoidance and automatic reset device includes a platform base, a fixed platform, a lifting platform, a drag chain and a driving mechanism. A support frame is provided at the upper end of the platform base. The fixed platform is arranged at the upper end of the support frame. The lifting platform is located on one side of the fixed platform, and an avoidance cover plate is arranged on one side of the fixed platform close to the lifting platform. A battery unlocking and locking device is installed on the lifting platform. One end of the drag chain is connected to the battery unlocking and locking device, and the other end is connected to the platform base. An S-shaped double bending joint is arranged on the drag chain close to the battery unlocking and locking device, and an S-shaped single bending joint is arranged at one end of the drag chain close to the platform base;

[0008] The driving mechanism drives the lifting platform to move up and down along the height direction of the support frame. The lifting platform includes a high position state and a low position state. When the lifting platform moves to the high position state, the lifting platform and the fixed platform are in the same plane, and the S-shaped double-bending joint bends and pushes the avoidance cover plate to open upward. When the lifting platform moves to the low position state, the S-shaped double-bending joint is straightened, and the avoidance cover plate is reset by the elastic resetting member.

[0009] Furthermore, the driving mechanisms are symmetrically arranged on the platform base. The driving mechanism includes a motor, a reducer, a coupling and a pin-tooth lifting chain, and the pin-tooth lifting chain is also called a rigid chain. The output end of the motor is connected to the reducer, the output end of the reducer is connected to the pin-tooth lifting chain through the coupling, and the output end of the pin-tooth lifting chain is connected to the bottom of the lifting platform.

[0010] Furthermore, the reducer has two output ends, and each is connected to the pin-tooth lifting chain through the coupling.

[0011] Furthermore, a scissor-type lifting mechanism is arranged between the lifting platform and the platform base. The scissor-type lifting mechanism includes scissor arms, sliders and slide rails. The upper end of the platform base and the bottom of the lifting platform are respectively provided with the slide rails, the sliders are slidably connected to the slide rails, one side of the scissor arms is fixedly arranged at the upper and lower ends, and the upper and lower ends of the other side of the scissor arms are respectively hinged to the sliders.

[0012] Furthermore, a first sensor, a second sensor and a third sensor are sequentially arranged on the moving path of the slider, and the slider is correspondingly provided with an induction piece.

[0013] Furthermore, the elastic resetting member is a tension spring, and the two ends of the tension spring are respectively connected to the fixed platform and the avoidance cover plate.

[0014] The beneficial technical effects of the present utility model are as follows:

[0015] First, through the setting of the S-shaped double-bending joint and the S-shaped single-bending joint, the interference problem between the drag chain and the platform is effectively solved. When the lifting platform is in the high position state, the S-shaped double-bending joint bends and pushes the avoidance cover plate to open upward, providing enough space for the drag chain to ensure the smooth operation of the battery unlocking and locking device; when the lifting platform descends to the low position state, the S-shaped double-bending joint returns to the straightened state, and the avoidance cover plate is automatically reset by the tension spring.

[0016] Second, a drive mechanism composed of a motor, a speed reducer, a coupling, and a pin-tooth lifting chain is adopted to achieve precise control of the lifting platform. The drive mechanism is symmetrically arranged on the platform base, making the movement of the lifting platform more stable and reliable. At the same time, the double-output design of the speed reducer is connected to the pin-tooth lifting chain through couplings respectively, further enhancing the load-bearing capacity and stability of the drive mechanism.

[0017] Third, a scissor-type lifting mechanism is also provided between the lifting platform and the platform base. The mechanism includes scissor arms, sliders, and slide rails, making the lifting process of the lifting platform more stable. In addition, the first sensor, the second sensor, and the third sensor arranged on the moving path of the slider provide position feedback for the device, making the entire battery swapping operation process more intelligent and automated.
