Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, and in particular to an automatic docking device for charging piles. Background Technology
[0002] With the increasing popularity of new energy vehicles, the ease of use and connection efficiency of charging piles, as core energy replenishment facilities, have become a focus of industry attention. Currently, the mainstream charging pile connection method is still primarily manual: users need to get out of the vehicle, manually pick up the charging gun, align it with the vehicle's charging port, insert it, and start charging; after charging is complete, they also need to manually unplug the charging gun and return it to its original position. This method not only increases the number of steps for users, but also easily leads to inconvenience, especially in inclement weather, and may even pose a risk of electric shock. Furthermore, manual connection relies on the user's skill level; if the insertion angle is incorrect or the force is insufficient, it may cause poor contact between the charging gun and the charging port, leading to problems such as overheating at the contact point and charging interruption, affecting charging efficiency and equipment lifespan.
[0003] To address the drawbacks of manual docking, some fields have attempted to introduce semi-automatic docking devices. However, existing technologies still have significant shortcomings: Firstly, most semi-automatic devices lack effective guiding structures, relying solely on drive components to propel the charging gun linearly. If the vehicle's parking position is slightly off, it cannot accurately align with the charging port, requiring users to repeatedly adjust the vehicle's position, thus failing to truly achieve "automatic docking." Secondly, some devices have rigid docking components, making them susceptible to physical wear and tear on the charging gun or vehicle's charging port if positional deviations occur during docking, increasing equipment maintenance costs. Furthermore, existing devices lack buffer protection during docking; rapid collisions between the charging gun and the charging port may damage internal circuit components, posing a safety hazard.
[0004] In public charging scenarios, manual connection also faces efficiency bottlenecks: during peak hours, when users are queuing, manual plugging and unplugging takes a long time, resulting in low efficiency of single-pile service; at the same time, for unattended charging stations, manual connection cannot meet the requirements of "unmanned operation", which restricts the intelligent development of charging piles.
[0005] To address this, an automatic docking device for charging piles is proposed. Utility Model Content
[0006] The purpose of this invention is to provide an automatic docking device for charging piles, aiming to solve or improve at least one of the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following solution: This utility model provides an automatic docking device for charging piles, comprising:
[0008] A slide rail assembly, which is horizontally mounted on the charging pile body;
[0009] A reciprocating motion drive assembly is mounted on the charging pile body, and a slider is mounted on the output end of the reciprocating motion drive assembly. The slider is slidably connected to the slide rail assembly.
[0010] A docking seat is mounted on the slider, and a charging plate is mounted on the docking seat. The charging plate is connected to the charging pile body via a cable.
[0011] Two guide plates are provided, which are respectively located on both sides of the charging plate and are installed on the end face of the docking seat.
[0012] The included angle between the guide plate and the charging plate is greater than 90°.
[0013] According to the present invention, an automatic docking device for charging piles is provided, wherein the slide rail assembly includes two slide rail bodies, which are installed at intervals on the charging pile body and are arranged laterally; the slider has two slide grooves, which are slidably connected to the two slide rail bodies respectively.

[0018] According to the present invention, an automatic docking device for charging piles is provided, wherein the included angle between the guide plate and the charging plate is 120° to 150°.
[0019] The present invention discloses the following technical effects:
[0020] This invention utilizes the synergistic effect of a reciprocating motion drive component, a slide rail component, and a slider to complete the docking action without manual intervention. The reciprocating motion drive component drives the slider to slide laterally along the slide rail component, causing the docking seat and charging plate to move synchronously. With the guidance of the two guide plates, the vehicle charging component can be automatically pushed into the charging plate to complete the docking, completely replacing the traditional manual plugging and unplugging operation, simplifying the user process. Users can complete the charging docking without getting out of the vehicle, achieving automatic docking and charging, and greatly improving the docking success rate.
[0021] This utility model uses two guide plates located on both sides of the charging plate with an angle greater than 90° to the charging plate to form an outward-expanding guide channel. When there is a slight left or right deviation in the vehicle's parking position, the vehicle's charging component first contacts the inclined surface of the guide plate. The guide plate guides the charging component to gradually correct itself to the front of the charging plate through the guiding force of the inclined surface. Then, in conjunction with the reciprocating motion drive component, the charging plate is pushed to make a slight lateral adjustment, achieving precise docking. This eliminates the need for users to repeatedly adjust the vehicle's parking position and significantly improves the docking success rate.
[0022] The docking seat and charging plate of this utility model are stably connected by a slider and a slide rail assembly. The reciprocating motion drive assembly drives the process smoothly without violent shaking or impact, which can prevent poor contact caused by the charging plate shifting during docking and ensure the safety and stability of the charging process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Reference Figure 1 This utility model provides an automatic docking device for charging piles, comprising:
[0029] A slide rail assembly is horizontally mounted on the charging pile body 1.
[0030] A reciprocating motion drive component is installed on the charging pile body 1. A slider 2 is installed at the output end of the reciprocating motion drive component, and the slider 2 is slidably connected to the slide rail component.
[0031] The docking seat 3 is mounted on the slider 2. The charging plate 6 is mounted on the docking seat 3. The charging plate 6 is connected to the charging pile body 1 via a cable.
[0032] Guide plate 4, there are two guide plates 4, which are located on both sides of the charging plate 6, and both guide plates 4 are installed on the end face of the docking seat 3.
[0033] The included angle between the guide plate 4 and the charging plate 6 is greater than 90°.
[0034] With this configuration, the present invention can complete the docking action without manual intervention through the synergistic effect of the reciprocating motion drive component, the slide rail component and the slider 2. The reciprocating motion drive component drives the slider 2 to slide laterally along the slide rail component, which drives the docking seat 3 and the charging plate 6 to move synchronously. With the guiding effect of the two guide plates 4, the vehicle charging component can be automatically pushed into the charging plate 6 to complete the docking, completely replacing the traditional manual plugging and unplugging operation, simplifying the user process. Users can complete the charging docking without getting out of the vehicle, realizing automatic docking and charging, and greatly improving the docking success rate.
[0035] This utility model uses two guide plates 4 located on both sides of the charging plate 6 with an angle greater than 90° to the charging plate 6 to form an outward-expanding guide channel. When there is a slight left or right deviation in the vehicle's parking position, the vehicle's charging component first contacts the inclined surface of the guide plate 4. The guide plate 4 guides the charging component to gradually correct itself to the front of the charging plate 6 through the guiding force of the inclined surface. Then, in conjunction with the reciprocating motion drive component, the charging plate is pushed to make a slight lateral adjustment, achieving precise docking. This eliminates the need for the user to repeatedly adjust the vehicle's parking position, significantly improving the docking success rate.
[0036] In this invention, the docking seat 3 and the charging plate 6 are stably connected to the slide rail assembly via the slider 2. The reciprocating motion drive assembly drives smoothly without violent shaking or impact, which can prevent poor contact caused by the charging plate shifting during docking and ensure the safety and stability of the charging process.
[0037] Further optimization of the design involves a slide rail assembly comprising two slide rail bodies 5, which are spaced apart and mounted on the charging pile body 1, arranged laterally. The slider 2 has two grooves, which are slidably connected to the two slide rail bodies 5. During the lateral movement and docking phase, when the reciprocating motion drive component moves the slider 2, the dual-rail structure effectively prevents tilting or displacement of the slider 2 due to uneven force on one side. Compared to a single-rail design, the two slide rail bodies 5 balance the force on the slider 2 from both sides, preventing the slider 2 from rotating around the slide rail during sliding and ensuring stable lateral movement. Simultaneously, the tight fit between the grooves and the slide rail bodies 5 reduces sliding gaps, preventing the slider 2 from shifting left and right during movement. This ensures that the docking seat 3, charging plate 6, and guide plate 4 connected to the slider 2 can move precisely along a preset path, providing a stable foundation for subsequent guidance, correction, and precise docking, reducing the risk of docking deviation caused by slider offset.
[0038] The scheme is further optimized. The reciprocating motion drive component includes an electric actuator and a control system. Both the electric actuator and the control system are installed on the charging pile body 1. The charging plate 6, the electric actuator, and the charging pile body 1 are all electrically connected to the control system. The telescopic end of the electric actuator is fixedly connected to the slider 2. The control system adopts a microcontroller or PLC.
[0039] In the initial preparation phase, after receiving the vehicle arrival signal, the control system first checks the circuit connectivity of the charging plate 6 and the position of the vehicle charging component. Once confirmed, it sends a start command to the electric push rod. During the lateral movement and docking phase, the telescopic end of the electric push rod drives the slider 2 to move smoothly along the slide rail body 5. The control system can adjust the telescopic speed of the electric push rod to control the movement rate of the slider 2, reducing its speed when approaching the vehicle charging component to avoid rapid collisions. In the guidance and correction phase, the control system fine-tunes the telescopic amount of the electric push rod based on the contact feedback between the vehicle charging component and the guide plate 4, causing the slider 2 to move slightly, assisting the guide plate 4 in correcting the charging component. After docking is complete, the control system detects a stable contact signal between the charging plate 6 and the vehicle charging component, immediately stopping the electric push rod and locking its telescopic end to prevent slider 2 from shifting. After charging is complete, the control system sends a reset command to the electric push rod, causing its telescopic end to retract in the opposite direction, returning slider 2 to its initial position. The entire process requires no manual intervention; the control system achieves intelligent control throughout the entire process, improving docking efficiency and accuracy.
[0040] To further optimize the design, a flexible pad is installed on the end face of the guide plate 4 near the charging plate 6; the material is an insulating material with good elasticity (such as silicone or rubber).
[0041] The design was further optimized so that the two guide plates 4 and the docking seat 3 were integrally formed.
[0042] The design was further optimized by using a stainless steel guide plate for guide plate 4.
[0043] The design was further optimized so that the angle between the guide plate 4 and the charging plate 6 is 120° to 150°.
