Description

Technical Field

[0001] This utility model relates to the technical field of access control and security systems for charging piles, and more specifically to an access control and security protection device and system for integrated charging and storage piles. Background Technology

[0002] Integrated energy storage and charging stations have stringent safety requirements and operate in relatively harsh environments. For ease of maintenance, all four side doors of the integrated charging station can be opened manually. However, to ensure safety and prevent accidental opening during normal operation, the main control unit is required to immediately report an access control fault and cut off high-voltage power supply when any side door of the charging station is opened.

[0003] Currently, some access control detection systems on the market use magnetic induction, which not only have complex control logic and can only achieve single-access protection, but also have relatively low reliability. Integrated charging piles require real-time monitoring of the opening and closing status of at least four side doors, while simultaneously minimizing the number of internal wiring harnesses and main control unit pins. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide an access control security protection device and system for integrated storage and charging piles, which solves the problem that some access control detection systems on the market currently use the magnetic induction principle, which not only have complex control logic and can only achieve single access control protection, but also have relatively low reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an access control security protection device and system for integrated storage and charging piles, comprising: a pile body, wherein side doors are provided on all four sides of the pile body and limit switches corresponding to the side doors are provided inside the pile body; a main control unit is provided inside the pile body and is electrically connected to the limit switches via wires; the limit switches include a mounting plate and a fixedly mounted outer shell is provided on the side of the mounting plate; a plug-in post is provided inside the outer shell and a spring post is provided on the surface of the plug-in post; a stop bar is provided on the surface of the outer shell and is slidably connected to the outer shell; a plug-in hole is provided inside the stop bar and a plug-in rod is inserted into the plug-in hole; the stop bar and the spring post are in contact with each other; a connecting plate is provided at the lower part of the stop bar and a moving contact is provided on the side of the connecting plate; a stationary contact is provided inside the outer shell and the stationary contact and the moving contact are corresponding to each other; and two sets of connecting wires are provided at the lower part of the stationary contact.

[0006] In a preferred embodiment of this utility model, one of the connecting lines is connected to the first pin of the main control unit and the other is connected to the second pin of the main control unit.

[0007] In a preferred embodiment of this utility model, the first pin of the main control unit provides a constant high level.

[0008] In a preferred embodiment of this utility model, a sealing ring is provided at the connection between the stop bar and the outer shell.

[0009] In a preferred embodiment of this utility model, the mounting plate has a plurality of sets of mounting holes arranged in a strip-shaped structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model features side doors on all four sides of the pile body, and corresponding limit switches inside the pile body. A main control unit is located inside the pile body and electrically connected to the limit switches via wires. Each limit switch includes a mounting plate with a fixed outer casing on its side. Inside the outer casing is a plug-in post with a spring post on its surface. A stop bar is located on the surface of the outer casing and is slidably connected to it. Inside the stop bar is a plug-in hole into which the plug-in post inserts. The stop bar and the spring post are in contact. A connecting plate is located at the lower part of the stop bar, and a movable... The charging pile has a stationary contact inside the housing, with the stationary contact and the moving contact corresponding to each other. Two sets of connecting wires are set at the bottom of the stationary contact. Limit switches are first installed at each side door of the charging pile. When the door is closed, the door panel presses the stop bar, causing the moving contact to contact the stationary contact. At this time, the two connecting wires are connected. When the door is opened, the moving contact separates from the stationary contact, and the two connecting wires are disconnected. Limit switches are installed on each side door of the charging pile. The output pin of the main control unit is connected to the input wire of any limit switch. Then, the limit switches are connected in series. The output wire of the last limit switch is connected to the input pin of the main control unit to form a closed loop circuit. Finally, one end of the series-connected limit switches is connected to the first pin of the main control unit, and the other end is connected to the second pin of the main control unit. A constant high level is provided on the first pin of the main control unit. When all limit switches are closed, the same high-level signal can be detected on the second pin. When one or more limit switches are open, no high-level signal will be detected on the pin. This enables real-time monitoring of the opening and closing status of multiple side doors of the integrated storage and charging pile. The opening and closing status is determined based on the displacement of the limit switches. The mechanical signal detection is simple and reliable, avoiding the complex magnetic induction detection process. The main control unit indirectly determines whether the door is open or not through high and low level signals. This level signal is easy to detect and reduces the software and hardware development costs. Multiple limit switches are connected in parallel, which can simultaneously detect the opening and closing status of any number of cabinet doors. Attached Figure Description

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.

[0018] Please see Figure 1-4This utility model provides a technical solution: an access control security protection device and system for integrated storage and charging piles, comprising: a pile body 1, with side doors 2 on all four sides of the pile body 1 and limit switches 3 corresponding to the side doors 2 inside the pile body 1; a main control unit 4 inside the pile body 1, which is electrically connected to the limit switches 3 via wires; the limit switches 3 include a mounting plate 5, and a fixedly mounted outer shell 7 is provided on the side of the mounting plate 5; a plug-in post 10 is provided inside the outer shell 7, and a spring post 11 is provided on the surface of the plug-in post 10; the outer shell... A stop bar 8 is provided on the surface of the housing 7, and the stop bar 8 is slidably connected to the housing 7. The stop bar 8 has a insertion hole 9 inside, and a connecting rod is inserted into the insertion hole 9. The stop bar 8 is in contact with the spring post 11. A connecting plate 13 is provided at the lower part of the stop bar 8, and a moving contact 14 is provided on the side of the connecting plate 13. A stationary contact 15 is provided inside the housing 7, and the stationary contact 15 corresponds to the moving contact 14. Two sets of connecting lines 16 are provided at the lower part of the stationary contact 15. Side doors 2 are provided around the pile body 1, and the inside of the pile body 1 is connected to the side doors 2. Corresponding limit switches 3 are provided. A main control unit 4 is installed inside the pile body 1, and the main control unit 4 is electrically connected to the limit switches 3 via wires. The limit switches 3 include a mounting plate 5, and a fixedly mounted outer shell 7 is provided on the side of the mounting plate 5. A plug-in post 10 is provided inside the outer shell 7, and a spring post 11 is provided on the surface of the plug-in post 10. A stop rod 8 is provided on the surface of the outer shell 7, and the stop rod 8 is slidably connected to the outer shell 7. A plug-in hole 9 is provided inside the stop rod 8, and the plug rod is inserted into the plug-in hole 9. The stop rod 8 and the spring post 11 are in contact with each other. A connecting plate 13 is provided at the bottom, and a moving contact 14 is provided on the side of the connecting plate 13. A stationary contact 15 is provided inside the outer casing 7, and the stationary contact 15 and the moving contact 14 correspond to each other. Two sets of connecting wires 16 are provided at the bottom of the stationary contact 15. First, the limit switch 3 is installed at each side door 2 of the charging pile 1. When the door is closed, the door panel presses the stop bar to make the moving contact 14 contact the stationary contact 15. At this time, the two connecting wires 16 are connected to each other. When the door is opened, the moving contact is separated from the stationary contact. At this time, the two connecting wires 16 are disconnected. Install the limit switch 3 on each side door 2 of the charging pile, and follow the instructions. Figure 4The limit switches 3 are connected in series, with one end connected to the first pin of the main control unit 4 and the other end connected to the second pin of the main control unit 4. A constant high level is provided on the first pin of the main control unit 4. When all limit switches 3 are closed, the same high-level signal can be detected on the second pin. When one or more limit switches 3 are open, no high-level signal will be detected on the pin. This enables real-time monitoring of the opening and closing status of multiple side doors 2 of the integrated storage and charging pile. The opening and closing status is determined based on the displacement of the limit switches 3. The mechanical signal detection is simple and reliable, avoiding the complex magnetic induction detection process. The main control unit 4 indirectly determines whether the door is open or not through high and low level signals. This level signal is easy to detect and reduces the software and hardware development costs. Multiple limit switches 3 are connected in parallel, which can simultaneously detect the opening and closing status of any number of cabinet doors.

[0019] Further improvements, such as Figure 3 , 4 As shown: one of the connecting lines 16 is connected to the first pin of the main control unit 4 and the other is connected to the second pin of the main control unit 4. By connecting the connecting lines 16 to different pins of the main control unit 4 respectively, a clear transmission path for the electrical signal is realized, the circuit connection is simplified, and the accuracy of signal detection is improved.

[0020] Further improvements, such as Figure 4 As shown: The first pin of the main control unit 4 provides a constant high level as a reference signal, which enables the main control unit 4 to accurately determine the opening and closing state of the door by detecting the level change on the second pin, thereby enhancing the stability and reliability of the system.

[0021] Further improvements, such as Figure 3 As shown: A sealing ring 12 is provided at the connection between the stop lever 8 and the outer casing 7. The sealing ring 12 effectively prevents external factors such as dust and moisture from entering the interior of the limit switch 3, thereby improving the durability and adaptability of the limit switch 3 to the working environment and reducing failures caused by environmental factors.

[0022] Further improvements, such as Figure 2 As shown: The mounting plate 5 has several sets of mounting holes 6 inside, and the mounting holes 6 are arranged in a strip structure. The strip structure of the mounting holes 6 provides more installation and adjustment space, making the installation of the limit switch 3 more flexible and convenient.

[0023] Working Principle: A corresponding limit switch 3 is installed at each side door 2 of the integrated charging pile. The limit switch 3 includes components such as a mounting plate 5, a housing 7, a stop lever 8, a spring column 11, a moving contact 14, and a stationary contact 15. By installing the limit switch 3, an independent switch status detection point is provided for each side door 2, ensuring that the switch status of each door can be accurately monitored. When the side door 2 is closed, the door panel presses the stop lever 8, causing the stop lever 8 to slide downwards, thereby driving the moving contact 14 to contact the stationary contact 15. At this time, the two connecting wires 16 below the stationary contact 15 are interconnected, forming a closed circuit. The closing status of the door is detected by mechanical contact, avoiding complex magnetic induction detection and improving the reliability and stability of the detection. At the same time, the closed circuit allows the main control unit 4 to detect a high-level signal, confirming that the door is closed. When the side door 2 is opened, the pressing action of the door panel on the stop lever 8 disappears, and the stop lever 8 slides upwards under the action of the spring column 11, separating the moving contact 14 from the stationary contact 15. At this point, the two connecting wires 16 below the stationary contact 15 are disconnected, breaking the circuit. The door's open state is detected through mechanical separation, avoiding the complexity of magnetic induction detection. The disconnection of the circuit prevents the main control unit 4 from detecting a high-level signal, thus confirming that the door is open. Upon detecting the door is open, the main control unit 4 immediately uploads access control fault information and cuts off the high-voltage power supply, ensuring the safety of the equipment.
