Description

Technical Field

[0001] This utility model relates to the technical field of charging piles, and in particular to an insulating structure for a short-circuit-proof, safe charging pile battery soft connection. Background Technology

[0002] With the rapid development of new energy vehicles, the safety of charging piles, as an important supporting facility for new energy vehicles, has received widespread attention. In the charging pile battery system, flexible connections are used to realize the current transmission between batteries or between batteries and other components. Their insulation performance directly affects the safe operation of the entire system. As a core supporting infrastructure for new energy vehicles, the safety performance of charging piles has become a key factor concerning the healthy development of the industry and the safety of users' lives and property. However, due to the long-term exposure of flexible connections to complex working conditions such as high-frequency vibration, drastic changes in temperature and humidity, and strong electric fields, their insulation layer is prone to aging and damage. Therefore, a short-circuit-proof insulation structure for charging pile battery flexible connections is particularly needed.

[0003] However, existing short-circuit protection safety charging pile battery flexible connection insulation structures only use a single insulation layer for wrapping during use. The insulation design has low redundancy and needs to withstand frequent bending, vibration, and temperature changes. The single insulation layer is prone to cracking due to local wear, aging, or stress concentration, leading to insulation performance failure. Most use simple binding or pasting methods and lack dedicated anti-displacement design. Under the vibration generated by equipment operation, external impact, or after long-term use, the insulation layer is prone to relative sliding with the flexible connection, or even completely falling off the installation position. Most do not have dedicated protective components. External dust, moisture, corrosive gases, etc., can easily penetrate into the equipment, adhere to the surface of the insulation layer, and gradually erode the insulation material, leading to a decrease in insulation performance. The heat dissipation structure has poor compatibility with the insulation components, and unreasonable exhaust vent placement can easily lead to excessively high local temperatures, accelerating the aging of insulation materials, further shortening the service life of the equipment, and reducing the safety protection level of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an insulation structure for a short-circuit-proof safe charging pile battery flexible connection, in order to solve the problems mentioned in the background art. Existing short-circuit-proof safe charging pile battery flexible connection insulation structures use only a single insulation layer for wrapping, resulting in low insulation design redundancy. They are subject to frequent bending, vibration, and temperature changes, and the single insulation layer is prone to cracking due to local wear, aging, or stress concentration, leading to insulation performance failure. They often use simple binding or pasting methods, lacking dedicated anti-displacement design. Under vibration generated during equipment operation, external impacts, or after long-term use, the insulation layer is prone to relative sliding with the flexible connection, or even detaching entirely from the installation position. Most lack dedicated protective components, allowing external dust, moisture, corrosive gases, etc., to easily penetrate the equipment, adhere to the insulation layer surface, and gradually erode the insulation material, leading to decreased insulation performance. The heat dissipation structure has poor compatibility with the insulation components, and improper exhaust vent placement can easily lead to excessively high local temperatures, accelerating insulation material aging, further shortening equipment lifespan, and reducing the equipment's safety protection level.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating structure for a short-circuit-proof, safe charging pile battery flexible connection, comprising a charging pile body, a charging cable disposed on the outer side of the charging pile body, a charging head fixedly connected to the end of the charging cable away from the charging pile body, a vent on the outer side of the charging pile body, a shield fixedly installed on the top of the charging pile body, a protective component disposed on the outer side of the charging pile body, a snap-fit ​​groove on the inner side of the charging pile body, an insulating component disposed inside the charging pile body, the insulating component including a mounting base, the mounting base being installed on the inner side of the charging pile body, a snap-fit ​​post fixedly installed on the outer side of the mounting base, a battery flexible connection body disposed on the top of the mounting base, a main insulating layer disposed on the outer side of the battery flexible connection body, an anti-displacement seat fixedly installed on the outer side of the main insulating layer, an elastic spring fixedly installed on the outer side of the anti-displacement seat, a limit post fixedly installed on the outer side of the anti-displacement seat, a fixing seat fixedly installed on the outer side of the elastic spring, a reinforced insulating layer disposed on the outer side of the battery flexible connection body, and an insulating sleeve disposed on the top of the reinforced insulating layer.

[0006] Preferably, the charging cable, charging head, and exhaust vent are provided in two identical sets, and the two sets of charging cables, charging heads, and exhaust vents are symmetrically distributed about the vertical center line of the charging pile body.

[0007] Preferably, multiple sets of the snap-fit ​​posts and snap-fit ​​slots are provided, and the multiple sets of snap-fit ​​posts and snap-fit ​​slots are all compatible.

[0008] Preferably, the anti-displacement seat, elastic spring, limiting post and fixing seat are provided in two identical sets, and the two sets of anti-displacement seat, elastic spring, limiting post and fixing seat are symmetrically distributed about the vertical center line of the battery soft connection body.

[0009] Preferably, the fixing base is fixedly connected to the inner wall of the charging pile body, the fixing base has a circular structure, and the fixing base is adapted to the limiting post.

[0010] Preferably, the protective component includes a fixing plate, which is installed on the outside of the charging pile body. A rotating shaft is rotatably installed on the outside of the fixing plate, a rotating plate is fixedly installed on the outside of the rotating shaft, a protective door is fixedly installed on the outside of the rotating plate, a connecting plate is fixedly installed on the outside of the protective door, and a lock seat is fixedly installed on the outside of the charging pile body.

[0011] Preferably, the fixed plate, rotating shaft and rotating plate are provided in two identical sets, and the two sets of fixed plates, rotating shaft and rotating plate are symmetrically distributed about the horizontal center line of the protective door, and the connecting plate and lock seat are compatible.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This short-circuit-proof safety charging pile battery flexible connection insulation structure, through the setting of insulation components and the setting of a double insulation structure of main insulation layer and reinforced insulation layer, forms an all-round protective enclosure for the battery flexible connection body. The main insulation layer is directly attached to the surface of the flexible connection, providing a basic insulation barrier, while the reinforced insulation layer and insulation sleeve further enhance the insulation strength and effectively block the current leakage path. The double insulation design greatly improves the redundancy of insulation performance. Even if local wear or aging occurs during long-term use, it can still maintain a reliable insulation effect, significantly reducing the risk of short circuit due to insulation failure, ensuring the safe operation of the charging pile battery system. The anti-displacement seat is connected to the fixed seat by an elastic spring. The system, in conjunction with the limiting posts, provides elastic restraint to the battery's flexible connection body, buffering positional shifts caused by vibration or external impact. The locking posts precisely engage with the locking slots inside the charging pile body, ensuring the overall stability of the insulation components within the equipment. The anti-displacement mechanism prevents the flexible connection and insulation structure from loosening or shifting due to long-term use or external interference, ensuring the continuity and reliability of insulation protection. Protective components are also included to effectively block the intrusion of external dust, moisture, and foreign objects, reducing the impact of environmental factors on insulation performance and lowering the risk of human-caused damage to the insulation structure. This further enhances the overall safety protection level of the charging pile, ensuring the balance of equipment operation, providing convenience for later maintenance, and reducing installation and maintenance costs.

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.

[0016] Please see Figure 1-4This utility model provides a technical solution: an insulating structure for a short-circuit-proof safe charging pile battery flexible connection, including a charging pile body 1, a charging cable 2 disposed on the outer side of the charging pile body 1, a charging head 3 fixedly connected to the end of the charging cable 2 away from the charging pile body 1, a vent 4 opened on the outer side of the charging pile body 1, a shield 5 fixedly installed on the top of the charging pile body 1, a protective component 6 disposed on the outer side of the charging pile body 1, a snap-fit ​​groove 7 opened on the inner side of the charging pile body 1, and an insulating component 8 disposed inside the charging pile body 1; the insulating component 8 includes a mounting base 801, the mounting base...

An anti-displacement seat 805 is fixedly installed on the outer side of the main insulation layer 804. An elastic spring 806 is fixedly installed on the outer side of the anti-displacement seat 805. A limit post 807 is fixedly installed on the outer side of the anti-displacement seat 805. A fixing seat 808 is fixedly installed on the outer side of the elastic spring 806. A reinforcing insulation layer 808 is located on the outer side of battery flexible connection body 803. 09. An insulating sleeve 810 is provided on the top of the reinforced insulation layer 809. Through the setting of the insulating component 8, the double insulation structure of the main insulation layer 804 and the reinforced insulation layer 809 forms a comprehensive protective enclosure for the battery flexible connection body 803. The main insulation layer 804 is directly attached to the surface of the flexible connection, providing a basic insulation barrier, while the reinforced insulation layer 809 and the insulating sleeve 810 further enhance the insulation strength and effectively block the current leakage path. The double insulation design significantly improves the redundancy of insulation performance. Even if local wear or aging occurs during long-term use, it can still maintain a reliable insulation effect, significantly improving insulation performance. To reduce the risk of short circuits caused by insulation failure and ensure the safe operation of the charging pile battery system, the anti-displacement seat 805 is connected to the fixed seat 808 through the elastic spring 806. Together with the limiting post 807, it forms an elastic limit on the battery soft connection body 803, which can buffer the position displacement caused by vibration or external impact. The locking post 802 precisely engages with the locking groove 7 on the inner side of the charging pile body 1, ensuring the overall installation stability of the insulation component 8 inside the equipment. The anti-displacement mechanism prevents the soft connection and insulation structure from loosening or shifting due to long-term use or external interference, ensuring the continuity and reliability of insulation protection.

[0017] Furthermore, the charging cable 2, charging head 3, and exhaust vent 4 are provided in two identical sets, and the two sets of charging cables 2, charging heads 3, and exhaust vent 4 are symmetrically distributed about the vertical center line of the charging pile body 1. By setting two sets of charging cables 2, charging heads 3, and exhaust vent 4, the needs of two new energy vehicles can be met for simultaneous charging, improving the utilization efficiency of the charging pile, avoiding the queuing problem caused by a single charging interface, making the weight and function distribution on both sides of the charging pile body 1 more balanced, reducing equipment tilting or structural damage caused by excessive load on one side, and the two sets of exhaust vent 4 can dissipate heat from both sides at the same time, accelerating the heat dissipation speed inside the charging pile, avoiding the impact of local high temperature on the performance of key components such as insulation components 8, and extending the service life of the equipment.

[0018] Furthermore, multiple sets of the same snap-fit ​​posts 802 and snap-fit ​​slots 7 are provided, and these multiple sets of snap-fit ​​posts 802 and snap-fit ​​slots 7 are all compatible. By providing multiple sets of snap-fit ​​posts 802 and snap-fit ​​slots 7, the firmness and stability of the connection between the mounting base 801 and the charging pile body 1 can be greatly improved. The installation and disassembly process is more convenient, and no complicated tools are needed. Assembly can be completed simply by snapping, which reduces the difficulty of installation and maintenance. At the same time, it ensures the positional accuracy of the mounting base 801 within the charging pile body 1, providing a reliable foundation for the stable operation of the insulation component 8.

By setting two sets of anti-displacement seats 805, elastic springs 806, limiting posts 807, and fixing seats 808, symmetrical clamping and limiting forces can be formed from both sides of the battery flexible connection body 803, making the constraint force on the flexible connection body more balanced, avoiding deformation or displacement caused by excessive force on one side, and ensuring that the elastic buffering and limiting functions on both sides play a role simultaneously when facing vibrations or impacts in different directions, improving the comprehensiveness and reliability of the anti-displacement effect, further ensuring the relative position stability of the insulation layer and the flexible connection body, and maintaining the continuity of insulation performance.

[0020] Furthermore, the fixed base 808 is fixedly connected to the inner wall of the charging pile body 1. The fixed base 808 has a circular structure and is adapted to the limiting post 807. By setting the fixed base 808 and the charging pile body 1, it is ensured that the entire anti-displacement system will not change position due to external force. It provides reliable support for the anti-displacement seat 805, the elastic spring 806 and the limiting post 807. It can guide the movement of the limiting post 807 and limit its movement within a preset range. It can also disperse the force brought by the limiting post 807 through the annular contact, reduce the local wear of the fixed base 808 and extend the service life of the anti-displacement mechanism.

[0021] Furthermore, the protective component 6 includes a fixing plate 601, which is installed on the outside of the charging pile body 1. A rotating shaft 602 is rotatably installed on the outside of the fixing plate 601. A rotating plate 603 is fixedly installed on the outside of the rotating shaft 602. A protective door 604 is fixedly installed on the outside of the rotating plate 603. A connecting plate 605 is fixedly installed on the outside of the protective door 604. A lock seat 606 is fixedly installed on the outside of the charging pile body 1.

[0022] Furthermore, two identical sets of fixing plates 601, rotating shafts 602, and rotating plates 603 are provided, and the two sets of fixing plates 601, rotating shafts 602, and rotating plates 603 are symmetrically distributed about the horizontal center line of the protective door 604. The connecting plate 605 and the lock seat 606 are compatible. By setting two sets of fixing plates 601, rotating shafts 602, and rotating plates 603, the stability and smoothness of the rotation process of the protective door 604 can be enhanced, making the force on the protective door 604 more balanced when opening or closing, avoiding jamming or tilting caused by force on one side, extending the service life of the protective component 6, ensuring that the protective door 604 can fit tightly against the charging pile body 1 after being closed and locked, improving the sealing performance of the protection, and further enhancing the protection effect on the internal components.

[0023] Working principle: First, the operator fixes one end of each of the two charging cables 2 to the preset interface on the outside of the charging pile body 1, ensuring a firm connection and good electrical performance. Then, the charging head 3 is fixedly connected to the other end of the charging cable 2, completing the wiring assembly. Next, two sets of exhaust vents 4 are symmetrically opened on the outside of the charging pile body 1, ensuring that the position of the exhaust vents 4 matches the internal heat dissipation requirements. Finally, the shield 5 is fixed to the top of the charging pile body 1 by bolts or welding, ensuring that it can effectively block rain, dust, and other debris. The battery flexible connection body 803 is pre-treated by tightly wrapping the main insulation layer 804 around the outside of the battery flexible connection body 803, which can be reinforced with insulating adhesive. Fit; then, a reinforcing insulation layer 809 is fitted over the outside of the main insulation layer 804, and an insulating sleeve 810 is installed on top of the reinforcing insulation layer 809 to ensure that the double insulation structure completely covers the flexible connection body. Next, the anti-displacement seat 805 is fixedly installed on the outside of the main insulation layer 804. One end of the elastic spring 806 is connected to the anti-displacement seat 805, and the other end is connected to the fixing seat 808. Simultaneously, the limiting post 807 is aligned with the annular structure of the fixing seat 808 and inserted into the appropriate position. The multiple sets of snap-fit ​​posts 802 on the outside of the mounting seat 801 are aligned with the snap-fit ​​groove 7 on the inside of the charging pile body 1. The mounting seat 801 is fixed inside the charging pile body 1 by snap-fit, ensuring that the mounting seat 801 is accurately and stably positioned. If loosening occurs, the mating depth between the snap-fit ​​post 802 and the snap-fit ​​groove 7 can be adjusted appropriately, or an insulating gasket can be added to enhance stability. Place the battery flexible connection body 803, which is wrapped with the insulating layer and equipped with the anti-displacement mechanism, on top of the mounting base 801 and adjust its position to be centered. Then, fix the fixing base 808 to the inner wall of the charging pile body 1 with bolts, ensuring that the annular structure of the fixing base 808 is adapted to the limiting post 807. At this time, the elastic spring 806 is in a slightly compressed state, and the elastic force makes the anti-displacement base 805 tightly fit the main insulating layer 804, realizing the elastic limitation of the battery flexible connection body 803. First, install the two sets of fixing plates 601 symmetrically at the preset positions on the outside of the charging pile body 1. Ensure that its horizontal centerline is aligned with the horizontal centerline of the protective door 604. Then, rotatably install the rotating shaft 602 on the outside of the fixed plate 601, and then fix the rotating plate 603 on the rotating shaft 602. Next, fix the protective door 604 to the rotating plate 603 to ensure that the protective door 604 can rotate flexibly around the rotating shaft 602. Finally, install the connecting plate 605 on the outside of the protective door 604 and fix the lock seat 606 at the corresponding position on the charging pile body 1 so that the connecting plate 605 and the lock seat 606 are compatible, and complete the assembly of the protective component 6. Check whether the opening and closing of the protective door 604 is smooth and whether it fits tightly against the charging pile body 1 after locking. If any problems are found, adjust the relevant components in time until they meet the design requirements.
