Description

Technical Field

[0001] This utility model relates to the field of charging cabinet technology, specifically to a roadside intelligent traffic cone automatic locking charging cabinet. Background Technology

[0002] Traffic cones are an essential tool in road maintenance, playing a vital role in guiding traffic flow and ensuring normal road maintenance operations. To reduce labor intensity, improve work efficiency, and enhance safety, numerous intelligent traffic cone technologies and products have emerged. However, the management of intelligent traffic cones, such as charging and storage, still primarily relies on manual labor, which is inconvenient and makes timely deployment difficult.

[0003] Therefore, the automatic locking charging cabinet for intelligent traffic cones on the roadside was proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic locking charging cabinet for roadside intelligent traffic cones that is easy to manage and store, allows for more timely deployment, has a simple control module, and consumes less energy.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an automatic locking and charging cabinet for intelligent traffic cones on the roadside, including a cabinet body. Inside the cabinet body are a trigger switch and a partition near the top panel. A power distribution box, a controller, and an antenna are connected to the partition. A sliding door track is connected to the front panel of the cabinet below the partition. A sliding door track is also connected to the bottom panel of the cabinet near the front panel. Multiple wireless chargers for charging the intelligent traffic cones are connected to the bottom panel along the extension direction of the sliding door track. The front panel of the cabinet body has an entrance and an exit for the intelligent traffic cones to enter and exit on both sides. An entrance door and an exit door are connected to the sliding door track. Electric push rods are connected between the entrance door, the exit door, and the front panel. The controller is electrically connected to the power distribution box, the antenna, the wireless chargers, and the electric push rods. The controller can control the electric push rods by using a dual-channel relay circuit or other methods to control the forward, reverse, and power-off functions of the motor (i.e., to achieve the forward, stop, and reverse functions of the motor, thereby controlling the opening and closing of the entrance and exit doors).

[0007] Preferably, the cabinet is rectangular.

[0008] Preferably, the number of trigger switches is equal to the number of wireless chargers.

[0009] Preferably, the number of wireless chargers is four.

[0010] Preferably, the trigger switch includes an insulating rod and multiple sets of normally open conductive springs connected at equal intervals on the insulating rod. Each set of conductive springs is connected in series with a wireless charger. The conductive springs are electrically connected to the controller. Squeezing the conductive springs can make a set of conductive springs that are close to each other conduct electricity. The insulating rod is fixedly connected to the upper part of the back panel of the cabinet.

[0011] Preferably, a camera is connected to the top panel of the cabinet, positioned directly above the entrance and exit, and electrically connected to the controller. When the controller detects the intelligent traffic cone entering the opening area via the camera, it controls the electric push rod to open the entrance door. After the entrance door opens, the controller sends an entry signal to the intelligent traffic cone via the LoRa network. When the controller detects the intelligent traffic cone entering the cabinet via the camera, it controls the electric push rod to close the entrance door. When the controller receives an outward deployment command, it first controls the electric push rod (and if a door control electromagnet is also provided, unlocks the door control electromagnet first) to open the exit door. After the exit door opens, the controller sends an exit signal to the intelligent traffic cone via the LoRa network. When the controller detects the intelligent traffic cone leaving the closing area via the camera, it controls the electric push rod to lock the exit door.

[0012] Preferably, the roadside intelligent traffic cone automatic locking charging cabinet further includes a solar power supply component, which includes an energy storage battery connected to the partition, a solar panel, and a connecting rod connecting the solar panel and the top plate. The energy storage battery is electrically connected to the controller.

[0013] Preferably, the controller is also electrically connected to a door control electromagnet, which is used for automatic locking and unlocking of the door to enhance security and sealing. When energized, it generates a strong magnetic force to attract the lock seat and firmly lock the door at the closed position. When the power is cut off, it is demagnetized and the door is unlocked. Existing products can be purchased and installed according to conventional settings.

[0014] Preferably, a display screen is connected to the front panel, and the display screen is electrically connected to the controller.

[0015] Preferably, an alarm is connected to the front panel, side panel, or top panel of the cabinet, and the alarm is electrically connected to the controller.

[0016] Preferably, the bottom of the cabinet is connected to a mounting base.

[0017] Preferably, the base plate has guide lines drawn on its surface to guide the movement of the intelligent traffic cones.

[0018] Preferably, the intelligent traffic cone stops moving when it detects that it is charging, and the intelligent traffic cone has a line-following navigation function (using existing line-following navigation technology) and can travel along the guide line.

[0019] Preferably, the intelligent traffic cone has a right-angle turning function.

[0020] Due to the adoption of the above technical solutions, the advantages of this utility model are as follows:

[0021] 1. This utility model eliminates the need for communication and positioning between the intelligent traffic cone and the cabinet after the intelligent traffic cone enters the cabinet. It allows the intelligent traffic cone to follow the guide line drawn on the bottom plate of the cabinet solely based on its own line-following navigation function. Simultaneously, combined with the setting of a trigger switch, the wireless chargers on which the intelligent traffic cones are parked are sequentially powered from inside the cabinet to the entrance as the entering intelligent traffic cones squeeze the trigger switch. This enables the intelligent traffic cones that enter the cabinet sequentially to stop on the corresponding wireless chargers for charging, which not only significantly simplifies the control module of the charging cabinet but also helps reduce the power consumption during real-time control.

[0022] 2. By introducing a trigger switch, this utility model simplifies or eliminates the communication and positioning control module for intelligent traffic cones entering the cabinet. With the reduction of functional modules, it helps to reduce the failure rate and improve the reliability and durability of the equipment.

[0023] 3. This utility model can realize the automatic storage and charging of intelligent traffic cones, which helps to reduce the labor intensity and management tasks of personnel.

[0024] 4. This utility model is convenient to set up at certain intervals on the roadside as needed, and is beneficial for remote control to mobilize intelligent traffic cones to the target area for timely deployment.

[0025] 5. After the intelligent traffic cone has completed its task, it can be easily remotely controlled and stored inside this utility model, making management convenient. Attached Figure Description

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] This utility model provides an embodiment of an automatic locking charging cabinet for intelligent roadside traffic cones. See [link / reference]. Figure 1 It includes a rectangular cabinet 10, a camera 2, a solar power supply component 50, a display screen 1, an alarm 4, and a mounting base 30.

[0038] The specific implementation method is described below:

[0039] The cabinet 10 contains a trigger switch 20 and a partition 17 near the top plate 11 of the cabinet 10. A power distribution box 70, a controller 80, and an antenna 90 are connected to the partition 17. A sliding door track 5 is connected to the partition 17 near the front panel 12 of the cabinet 10. A sliding door track 5 is also connected to the bottom plate 13 of the cabinet 10 near the front panel 12. Guide lines (not shown) from the entrance 16 to the exit 15 are drawn on the bottom plate 13. Four wireless chargers 6 are evenly spaced along the sliding door track 5 on the bottom plate 13. Power supplies are located on both sides of the front panel 12 of the cabinet 10. The intelligent traffic cone 40 has an entrance 16 and an exit 15. An entrance door 7 and an exit door 8 are slidably connected to the sliding door track 5. An electric push rod 100 is connected to the front panel 12 via a push rod bracket (e.g., a universal fisheye bearing seat or a U-shaped bracket). Specifically, the tail of the electric push rod 100 is connected to the front panel 12 via a push rod bracket, and the telescopic head of the electric push rod 100 is connected to the entrance door 7 and the exit door 8 via push rod brackets. The controller 80 is connected to the distribution box 70, antenna 90, wireless charger 6, and electric push rod 100 via wires 60. (See also...) Figure 2 , Figure 3 , Figure 4 .

[0040] The number of trigger switches 20 is equal to the number of wireless chargers 6. Each trigger switch 20 includes an insulating rod 21 and multiple sets of normally open conductive spring contacts 22 connected at equal intervals to the insulating rod 21. Each set of conductive spring contacts 22 is connected in series with one wireless charger 6. The conductive spring contacts 22 are connected to the controller 80 via wires 60. When the intelligent traffic cone 40 presses the conductive spring contacts 22, it can make the adjacent set of conductive spring contacts 22 conductive. The insulating rod 21 is fixedly connected to the upper part of the back panel 14 of the cabinet 10. See [reference needed]. Figure 1 , Figure 4 , Figure 5 , Figure 6 .

[0041] The camera 2 is connected to the top plate 11 and is located directly above the entrance 16 and exit 15. The camera 2 is connected to the controller 80 via a wire. See [link / reference needed]. Figure 2 , Figure 3 .

[0042] The solar power supply assembly 50 includes an energy storage battery 51 connected to the partition 17, a solar panel 3, and a connecting rod 52 connecting the solar panel 3 and the top plate 11. The energy storage battery 51 is connected to the controller 80 via a wire 60. See below. Figure 4 .

[0043] The display screen 1 and the alarm 4 are both connected to the front panel 12 and are connected to the controller 80 via wires 60. (See below) Figure 1 , Figure 4.

[0044] The mounting base 30 is welded to the bottom of the cabinet 10, see [reference]. Figure 2 , Figure 3 .

[0045] In this embodiment, the camera 2 is a 3D camera, model: ORBBEC Astra ProPlus (0.6-8m); operating system: Linux; algorithm: using the lightweight YOLOv8n algorithm for traffic cone detection, based on the output 2D boundary frame and confidence level, the depth map is obtained through the 3D camera to calculate the position of the intelligent traffic cone 40, thereby determining whether it has entered the gate area; controller hardware model: Orange Pi AI Pro development board (8T computing power, 16G memory), the controller 80 sends entry and exit signals to the intelligent traffic cone 40 through the LoRa network. When the camera 2 detects that the intelligent traffic cone 40 has entered the gate area, the controller 80 (with an electric door control module, using existing technology) controls the electric push rod 100 to open the entrance door 7. After the entrance door 7 is opened, the controller 80 sends an entry signal to the intelligent traffic cone 40 through the LoRa network. When the camera 2 detects that the intelligent traffic cone 40 has entered the cabinet 10, the controller 80 controls... The electric push rod 100 locks the entrance door 7; when the controller 80 receives the deployment command, it controls the electric push rod 100 to open the exit door 8. After the exit door 8 is opened, the controller 80 sends an exit signal to the intelligent traffic cone 40 through the LoRa network. When the controller 80 senses that the intelligent traffic cone 40 has left the gate area through the camera 2, it controls the electric push rod 100 to lock the exit door 8. When the intelligent traffic cone 40 detects that it is in a charging state, it stops moving. The intelligent traffic cone 40 has a right-angle turning function and a line-following navigation function and can travel along the guide line.

[0046] In this utility model, the limiting of the entrance door 7 and the exit door 8 can be selected by an electric push rod 100 with a limiting function, or a mechanical limit switch (travel switch) can be used. A baffle is installed at the fully open and closed positions of the door. When the door moves to the position, the baffle presses down the limit switch and cuts off the motor power.

[0047] In this invention, the intelligent traffic cone 40 stops moving when it detects a charging state by: the "charging state" pin of the lithium battery charging chip changes with the charging state (charging in / fully charged), and the controller of the intelligent traffic cone 40 can send a command to control the intelligent traffic cone 40 to stop moving by detecting the state of the pin.

[0048] When this utility model is applied, it can be fixedly installed on the side of the highway at intervals by the mounting base 30, with the front panel 12 facing the center of the road, according to actual needs.

[0049] The charging process of this utility model for storing intelligent traffic cones 40 is as follows:

[0050] S1. The intelligent traffic cone 40 enters the recognition area of ​​the cabinet 10. The controller 80 controls the electric push rod 100 to retract, opening the entrance door 7. (See below) Figure 3 ;

[0051] S2. After the entrance door 7 is opened, the controller 80 of the cabinet 10 sends an entry command to the intelligent traffic cone 40, and the intelligent traffic cone 40 enters the cabinet 10.

[0052] S3. The first intelligent traffic cone 40 moves along the guide line to the innermost charging position (above the wireless charger 6). At this point, because the cone 41 presses against the conductive spring 22, the circuit of the innermost wireless charger 6 is connected, while the other conductive springs 22 are in an open circuit state because they are not pressed. It then begins charging and stops moving. The remaining intelligent traffic cones 40 also move along the guide line within the cabinet 10 until, according to their order of entry, they stop at the charging positions (above the magnetic resonance coil of the wireless charger 6) from the inside towards the entrance 16 and begin charging. See [link to relevant documentation]. Figure 1 (To better illustrate the charging status of the intelligent traffic cone 40, the exit gate 8 is shown as open.)

[0053] The working process of this utility model for automatically locking and opening / closing the door is as follows:

[0054] S1, Standby state: The door is in the closed position (the door control electromagnet is energized, generating magnetic force to firmly hold and lock the door, and the electric push rod 100 is in the extended state and self-locking when the power is off).

[0055] S2, Door opening trigger: Antenna 90 (such as radar, button) detects a valid signal and sends it to controller 80.

[0056] S3, Unlock: The controller 80 first sends a signal to the door control electromagnet driver to cut off the power supply to the door control electromagnet. When the electromagnetic force disappears, the door (entrance door 7) is unlocked.

[0057] S4. Door opening motion: After a short delay (to ensure full unlocking), the controller 80 starts the electric push rod driver, the push rod retracts, and pulls the door (entrance door 7) along the sliding door track 5 in the opening direction.

[0058] S5, Door opening limit: When the entrance door 7 reaches the fully open position, the "fully open limit switch" is triggered, or the controller determines the position through timing / encoder, and the controller 80 controls the push rod motor to stop.

[0059] S6. Door Opening Retention: The entrance door 7 remains in the fully open position until the intelligent traffic cone 40 enters.

[0060] S7. Closing motion: When the holding time ends, the controller 80 starts the electric push rod 100 in the reverse direction. The push rod extends and pushes the entrance door 7 to move in the closing direction.

[0061] S8. Door closing buffer and locking:

[0062] S9. When the entrance door 7 is close to closing, the infrared anti-pinch sensor is triggered (selectable as needed). If there is an obstacle, the door will stop or reverse.

[0063] S10, entrance door 7 reaches the fully closed position, triggering the "fully closed limit switch".

[0064] S11, Controller 80 stops the push rod motor.

[0065] S12, the controller 80 sends a signal to the gate control electromagnet driver to energize the gate control electromagnet, causing the electromagnet to engage and complete the locking process.

[0066] The aforementioned door system includes the entrance door 7 and the exit door 8. When the intelligent traffic cone 40 receives an exit deployment command, the controller 80 controls the exit door 8 to open until the intelligent traffic cone 40 is fully exiting the cabinet, and then executes the closing and locking process of the exit door 8. This is existing technology and will not be described in detail. When no door control electromagnet is installed, the electric push rod 100 with a "self-locking function" is preferred. The controller 80 can directly control the electric push rod 100 to open and close the door system through the included electric door control module.

[0067] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
