[0024] Example 1

[0025] like Figures 1 to 6 As shown, Figure 1 This is a schematic diagram (top view) of a three-stage guiding device for a battery swapping system provided in an embodiment of this utility model; Figure 2 This is a schematic diagram (front view) of the three-stage guiding device of the battery swapping system provided in this embodiment of the utility model; Figure 3 This is a three-dimensional structural diagram of a three-stage guiding device for a battery swapping system provided in an embodiment of this utility model; Figure 4This is a partial structural schematic diagram of the secondary guide component provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of the three-stage guide vibration damping assembly provided in this embodiment of the utility model; Figure 6 This is a partial structural schematic diagram of the three-stage guiding device of the battery swapping system provided in this embodiment of the utility model.

[0026] In this embodiment, the three-stage guiding device of the battery swapping system includes: a primary guiding component 200, disposed on the main frame 100 of the battery swapping system, for primary guidance of the battery swapping vehicle; the primary guiding component 200 includes multiple guide sliders 210, each guide slider 210 having a guide ramp at its top, and the guide ramps of the multiple guide sliders 210 being arranged facing each other; a secondary guiding component 300, located inside the primary guiding component 200, for secondary guidance of the battery swapping vehicle; the secondary guiding component 300 includes multiple guide posts 310; and a tertiary guiding vibration damping component 400, located within the secondary guiding component. The inner side of component 300 is used for three-level guidance and vibration reduction of the battery swapping vehicle; the three-level guidance and vibration reduction component 400 includes a guide plane 410 and multiple hydraulic dampers 420. Multiple battery docking interfaces 411 are provided in the central area of ​​the guide plane 410, and the battery components of the battery swapping vehicle are snapped together through the multiple battery docking interfaces 411; the multiple hydraulic dampers 420 are evenly spaced between the main frame 100 of the battery swapping system and the guide plane 410, and each hydraulic damper 420 is fitted with a buffer spring 430. Both the hydraulic damper 420 and the buffer spring 430 are used for buffering and vibration reduction.

[0027] In one optional embodiment, multiple guide sliders 210 are symmetrically distributed on the main frame 100 of the battery swapping system, and each guide ramp surface is provided with a wear-resistant coating. Notably, the guide ramps at the top of the multiple guide sliders 210 are arranged facing each other, enabling adaptive adjustment of the initial position deviation of the battery swapping vehicle through coarse guidance. Even if the initial angular deviation is large, it can be quickly corrected, avoiding repeated and time-consuming adjustments and improving battery swapping efficiency. By applying a wear-resistant coating to the guide ramps of the guide sliders 210, wear caused by frequent contact during battery swapping is reduced, extending the service life of components and ensuring long-term stability of the guiding function.

[0028] In one optional embodiment, multiple guide posts 310 are symmetrically distributed in the central area of ​​the main frame 100 of the battery swapping system. During secondary guidance, the guide sleeve of each battery swapping vehicle is correspondingly fitted onto the guide post 310 and can slide relative to the guide post 310. For example, the guide post 310 and the guide sleeve are in clearance fit, which is used to finely adjust the chassis of the battery swapping vehicle by adjusting the level of the guide post 310 and the guide sleeve. That is, the guide sleeve of the battery swapping vehicle slides down the guide post 310 by its own weight, and the horizontal position deviation is adaptively corrected by the clearance fit.

[0029] In an optional implementation, the lower end of each guide post 310 is disposed on a limiting seat 320, which is used to limit the axial travel of the guide sleeve, prevent excessive movement during the battery swapping process, ensure that the fine-tuning process is safe and controllable, and reduce the risk of equipment damage.

[0030] In an optional embodiment, the secondary guide assembly 300 further includes multiple position sensors 330. Each position sensor 330 is disposed near the lower end of a plurality of guide posts 310 and mounted on a corresponding limiting seat 320 for monitoring the position of the battery swapping vehicle. For example, the position sensors 330 can be used to monitor the height or horizontal movement position of the battery swapping vehicle.

[0031] The principle behind this system is to utilize the sliding connection between the guide post 310 and the guide sleeve, along with the limiting seat 320 to restrict the travel, to achieve millimeter-level precise positioning of the battery swapping vehicle chassis or battery pack. This ensures complete alignment between the battery and the vehicle interface, eliminating the risk of misalignment during insertion and removal. Furthermore, multiple position sensors 330 monitor the positional deviation of the battery swapping vehicle in real time and provide feedback data, providing a basis for accurately aligning the battery pack of the vehicle, thus improving the accuracy and safety of the battery swapping process.

[0032] In an optional embodiment, the central region of the guide plane 410 is provided with multiple battery docking interfaces 411 for connecting the battery pack of the battery swapping vehicle. A pressure sensor (not shown) is provided at the bottom of the guide plane 410 to monitor the contact pressure between the battery pack of the battery swapping vehicle and the battery docking interface 411. The guide plane 410 is used to engage the battery pack, precisely control the battery insertion and removal path, ensure the stability and alignment of the battery during insertion or removal, and reduce operational errors. The pressure sensor monitors the contact pressure between the battery pack and the battery docking interface 411, providing real-time feedback on the connection status to ensure the reliability and safety of the interface connection. For example, when the position sensor 330 detects that the sliding sleeve has bottomed out and the pressure sensor reaches a threshold, the docking is considered complete.

[0033] In one alternative embodiment, multiple hydraulic shock absorbers 420 and multiple buffer springs 430 jointly support the guide plane 410 and are used to jointly absorb the impact when the battery pack of the battery swapping vehicle separates from or connects to the battery docking interface 411. Through the coordinated work of the evenly spaced hydraulic shock absorbers 420 and buffer springs 430, the impact force when the battery pack separates from or connects to the battery docking interface 411 is absorbed, buffered and damped, and the electrical components are prevented from being damaged by rigid impact.

[0034] In an optional embodiment, the three-level guidance device of the battery swapping system further includes a battery swapping controller 500, which is disposed on the main frame 100 of the battery swapping system and electrically connected to the position sensor 330, the battery docking interface 411 and the pressure sensor, respectively, and is communicatively connected to the management system of the battery swapping station to monitor the working status of the battery swapping vehicle and its battery components.

[0035] The working principle of the three-stage guiding device of the battery swapping system of this utility model is as follows:

[0036] In actual battery swapping operations, when a battery swapping vehicle enters the battery swapping station, it first contacts the primary guide component 200. The guide slider 210 guides the battery swapping vehicle to the preset battery swapping position. Even if there is a certain deviation in the angle at which the battery swapping vehicle enters, it can be adaptively adjusted by the guidance of the guide ramp.

[0037] The guide posts 310 of the secondary guide assembly 300 are symmetrically distributed on the main frame 100 of the battery swapping system. The primary guide assembly 200 provides initial positioning, and the guide posts 310, in conjunction with the guide sleeves, make fine adjustments to the position of the battery swapping vehicle chassis or battery components. The position sensor 330 monitors the position deviation of the battery swapping vehicle in real time to ensure that the battery swapping vehicle is accurately aligned with the battery replacement area.

[0038] The three-stage guide vibration damping assembly 400 ensures that the battery assembly and the battery docking interface 411 are aligned. The battery assembly is tightly held in place by the battery docking interface 411 of the guide plane 410, and the insertion and removal path of the battery assembly is precisely controlled. At the same time, the hydraulic damper 420 and the buffer spring 430 work together to buffer the impact force when the battery assembly and the battery swapping vehicle are joined or separated. For example, when the battery assembly is inserted into the interface of the battery swapping vehicle, the three-stage guide vibration damping assembly 400 can absorb the impact force of the battery being pushed, ensuring the smoothness and safety of the entire battery swapping process, and improving the battery swapping efficiency and equipment lifespan.

[0039] The battery swapping controller 500 monitors the operating status of the battery swapping vehicles and their battery components, providing accurate data for battery swapping decisions and ensuring that the batteries operate safely and efficiently. It also communicates with the management system of the battery swapping station and the control system of the battery swapping vehicles, enabling seamless integration between the vehicles and the system. This achieves unmanned and automated battery swapping operations, improving efficiency and accuracy. The controller 500 also records and statistically analyzes various data during the swapping process, such as the number of swaps. Analysis of this data allows for optimization of the swapping process, rational scheduling of equipment maintenance, and provides data support for optimized battery design and operational management, ultimately improving overall operational efficiency and economic benefits.

[0040] It is worth noting that, compared with the existing battery swapping system's guidance and vibration reduction technologies, this utility model achieves precise guidance and vibration reduction through a three-level progressive coordination of guidance and vibration reduction, utilizing the battery swapping controller 500. This effectively solves the problems existing in the current battery swapping system in terms of guidance accuracy, vibration reduction effect, and battery swapping efficiency, such as improving the docking accuracy between the battery and the vehicle and reducing vibration and impact during the battery swapping process.

[0041] This utility model's three-stage guiding device for battery swapping significantly improves battery swapping efficiency and safety through the progressive synergy of three-stage guidance and vibration damping. The first-stage coarse guidance adapts to initial vehicle position deviations through a fault-tolerant design, avoiding time-consuming repeated adjustments; the second-stage guidance's millimeter-level precise positioning ensures perfect alignment between the battery and the vehicle interface, eliminating the risk of misalignment during insertion and removal; the third-stage vibration damping unit absorbs the impact force from interface separation through a composite buffering mechanism, preventing damage to electrical components.
