Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a ceiling-mounted charging pile with active obstacle avoidance function. Background Technology

[0002] Ceiling-mounted charging stations are an innovative solution for installing charging equipment on the roof of garages or parking lots. This design not only improves safety by reducing the risk of equipment damage and cable tripping, but also integrates highly convenient and intelligent functions, such as automatically lifting and retracting charging cables. Some high-end models even integrate track movement and visual recognition technology, which can automatically locate the vehicle's charging port and complete the docking.

[0003] However, this design still presents certain safety hazards in practical applications: if the installation location is not chosen properly, or if a large vehicle passes by, the charging station may obstruct vehicle passage. If the driver fails to notice in time, it could easily lead to a collision, and in severe cases, even cause equipment damage, electrical leakage, or fire, posing a significant safety risk. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention provides a ceiling-mounted charging pile with active obstacle avoidance function.

[0005] Technical Solution: A ceiling-mounted charging pile with active obstacle avoidance function includes a ceiling panel, on which a multi-stage telescopic rod is fixedly connected. A connecting rod is fixedly connected to the telescopic end of each telescopic rod. A charging box is ball-jointed to the connecting rod. An adapter is slidably connected to the charging box. A charging cable is provided on the adapter. A charging gun is fixedly connected to the charging cable and plugged into the charging box. A monitor is fixedly connected to the connecting rod. Mirror-distributed electric push rods are fixedly connected to the charging box. A fixing block is fixedly connected to the telescopic end of each electric push rod. The fixing block is used to fix the connecting rod to the charging box.

[0006] Preferably, a mirror-distributed stabilizing roller is rotatably connected to the ceiling panel, a torsion spring is provided between the stabilizing roller and the ceiling panel, a connecting belt is wound around the stabilizing roller, the charging box is fixedly connected to a fixing frame, and the connecting belt is fixedly connected to the fixing frame.

[0007] Preferably, an outer sleeve is fixedly connected to the adapter, and a spring is provided between the outer sleeve and the charging box.

[0008] Preferably, the charging box is fixedly connected to a temperature measuring ring, which is provided with an annular sliding groove and a circumferentially arrayed cylindrical sliding groove. The temperature measuring ring is slidably connected to a circumferentially arrayed sliding rod, which is slidably connected to a rotating frame. The rotating frame is provided with a circumferentially arrayed limiting groove, and a limiting rod is slidably connected in the limiting groove. The limiting rod is fixedly connected to a limiting block, which is used to press and limit the outer sleeve. The temperature measuring ring is provided with a circumferentially arrayed temperature measuring block, which is used to push the adjacent sliding rod.

[0009] Preferably, it further includes a winding frame, which is rotatably connected to the fixed frame, and the winding frame is rotatably connected to a circumferentially arrayed distribution of dispersed rods, and the charging cable is wound around the winding frame.

[0010] Preferably, the dispersing rod is provided with evenly distributed protrusions, and a cylinder is rotatably connected to the fixing frame, the cylinder being fixedly connected to the winding frame.

[0011] Preferably, a fixing rod is fixedly connected to the fixing frame, a fixing toothed ring is fixedly connected to the fixing rod, the winding frame is rotatably connected to the fixing toothed ring, and a driving gear is fixedly connected to the dispersing rod, the driving gear meshing with the fixing toothed ring.

[0012] Preferably, a fixed shell is fixedly connected to the fixed frame via a mounting bracket, and a mirror-distributed scraping ring is fixedly connected to the fixed shell. The scraping ring is slidably connected to the charging cable.

[0013] Preferably, the charging gun is fixedly connected to a mounting ring via a mounting rod, and the mounting ring is fixedly connected to a limiting sleeve, which is used to limit the lowest point of the charging cable.

[0014] Preferably, the limiting sleeve is always located on the side of the charging gun away from the ceiling panel.

[0015] Compared with other existing technologies, the advantages of this invention are as follows: This invention monitors the surrounding environment of the charging box in real time through a monitor, and issues an alarm when an obstacle poses a collision risk to the charging box. If the alarm does not stop the obstacle, the charging box will tilt and rotate when the obstacle comes into contact with it, ensuring the structural safety of the charging box and improving the safety of the device. Through a rapid physical disconnection mechanism between the charging box and the adapter, the connection between the cable and the charging station can be actively severed in the event of a fire, constructing a crucial passive safety barrier, thereby effectively preventing open flames from spreading along the cable to the vehicle and greatly reducing the potential for fire. The "fire spreading to multiple camps" type of secondary disaster risk provides crucial protection for the safety of people and property. By using a dispersing rod to drive the evenly distributed protrusions on it to rotate, the protrusions continuously vibrate the charging cable during the winding process, thereby releasing the internal stress generated during the twisting and winding process, allowing the various parts of the charging cable to "reset" and become loose, making it easier to straighten and store (the same principle applies to the release process of the charging cable, and the vibration applied during the release process can prevent the outer ring of the charging cable from tightening and locking, so that it maintains a relatively loose structure as a whole, achieving smooth release), thereby improving the service life of the charging cable.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 This embodiment discloses a ceiling-mounted charging pile with active obstacle avoidance function to prevent hard collisions between the charging pile and vehicles.

[0020] The specific structure and connection relationships of the charging station are as follows: like Figures 1-3 As shown, the charging station includes a ceiling panel 1. A multi-stage telescopic rod 2 is fixedly connected to the lower side of the ceiling panel 1. A connecting rod 3 is fixedly connected to the telescopic end of the multi-stage telescopic rod 2. The connecting rod 3 consists of a cylindrical rod and a ball. A charging box 4 is ball-connected to the connecting rod 3. The charging box 4 contains a power supply. An adapter 5 is slidably connected to the right side of the charging box 4. A charging cable 51 is installed on the right side of the adapter 5. The two are always electrically connected. The charging box 4 and the adapter 5 are also electrically connected. A charging gun 6, which is plug-in connected to the charging box 4, is fixedly connected to the end of the charging cable 51 away from the adapter 5. A monitor 7 is fixedly connected to the connecting rod 3. The detector 7 is equipped with a visual monitoring module and an alarm module. The charging box 4 is fixedly connected to two electric push rods 8 that are mirror-distributed to the left and right. The telescopic end of the electric push rod 8 is fixedly connected to a fixing block 9. The fixing block 9 is a hard rubber block (any hard material with a certain deformation capacity can be replaced equally). The fixing block 9 is used to fix the connecting rod 3 and the charging box 4. Two stabilizing rollers 101 that are mirror-distributed to the left and right are rotatably connected to the ceiling plate 1. A torsion spring (not shown in the figure) is set between the stabilizing roller 101 and the ceiling plate 1. A connecting belt 102 is wound around the stabilizing roller 101. The charging box 4 is fixedly connected to a fixing frame 103 that is fixedly connected to the connecting belt 102.

[0021] like Figure 2 , Figure 4 and Figure 5 As shown, an outer sleeve 10 is fixedly connected to the outer periphery of the adapter 5. A spring is provided between the outer sleeve 10 and the charging box 4. When the adapter 5 is inserted into the charging box 4, the spring is in a compressed state. A temperature measuring ring 11 is fixedly connected to the right side of the charging box 4. The temperature measuring ring 11 is provided with an annular groove and a circumferentially arrayed cylindrical groove. The temperature measuring ring 11 is slidably connected to a circumferentially arrayed sliding rod 12. Initially, the sliding rod 12 slides in the corresponding cylindrical groove. When the sliding rod 12 slides out of the corresponding cylindrical groove, the sliding rod 12 slides in the annular groove, allowing all the sliding rods 12 to slide together. A rotating frame 13 is connected, and a circumferentially arrayed limiting groove 14 is provided on the rotating frame 13. The limiting groove 14 is an arc-shaped groove, and a limiting rod 15 is slidably connected in the limiting groove 14. A limiting block 16 is fixed to the side of the limiting rod 15 near the axis of the adapter 5. The limiting block 16 is used to press and limit the outer sleeve 10. The side of the limiting block 16 near the outer sleeve 10 is provided with an inclined surface, so that the limiting block 16 can be pressed outward by the outer sleeve 10. A circumferentially arrayed temperature measuring block 17 is provided on the temperature measuring ring 11. The temperature measuring block 17 is made of thermally expanding material, and the temperature can only be triggered when exposed to an open flame. The temperature measuring block 17 is used to push the adjacent sliding rod 12 to the right.

[0022] The working process of the charging pile in this embodiment is as follows: Preparation process: First, install the ceiling panel 1 at the designated position on the top of the garage using bolts. Then, turn on the power in the charging box 4. The preparation work is complete.

[0023] Working process: When charging is required, the user controls the extension end of the multi-stage telescopic rod 2 to extend. The extension end of the multi-stage telescopic rod 2 drives the charging box 4 and its parts to gradually move down through the connecting rod 3. The charging box 4 pulls the connecting belt 102 through the fixing frame 103. The connecting belt 102 drives the stabilizing roller 101 to rotate, and at the same time twists the torsion spring between the stabilizing roller 101 and the ceiling panel 1, thereby providing stable support for the charging box 4 until the charging box 4 moves down to the designated position. The user then unplugs the charging gun 6 from the charging box 4 and pulls the charging cable 51 to the designated length (so that the charging gun 6 can be plugged into the car charging port), and then charging begins.

[0024] Once the car is fully charged, the user unplugs the charging gun 6 from the car's charging port and reconnects it to the charging box 4. The user then manually coils the charging cable 51 and hangs it on the charging box 4 until the charging cable 51 is coiled up and the charging box 4 is returned to its original position using the multi-stage telescopic rod 2. At this point, the device is complete.

[0025] After the device is installed, if an obstacle passes by and is about to collide with the device, the monitor 7 on the connecting rod 3 will first detect the approaching obstacle. When the obstacle gets too close, the monitor 7 will sound an alarm and control the telescopic end of the electric push rod 8 to retract. The telescopic end of the electric push rod 8 will drive the fixing block 9 to retract, thereby causing the fixing block 9 to lose contact with the connecting rod 3 (i.e., lose the fixation between the connecting rod 3 and the charging box 4). If the alarm does not stop the obstacle, when the obstacle comes into contact with the charging box 4, the charging box 4 will tilt and rotate to ensure the structural safety of the charging box 4. After the obstacle moves away, the charging box 4 will reset under the action of gravity. Then the monitor 7 will control the telescopic end of the electric push rod 8 to reset, and the connecting rod 3 and the charging box 4 will be re-fixed, and the work will be completed.

[0026] If the charging box 4 catches fire due to a malfunction during charging, the following steps must be taken to prevent the open flame from spreading to the car along with the charging cable 51 and causing a greater safety hazard: When the charging box 4 catches fire due to a malfunction, the temperature of the charging box 4 and the temperature measuring ring 11 rises rapidly. The abnormal temperature rise causes the temperature measuring block 17 to expand, which pushes the sliding rod 12 to the right, causing the sliding rod 12 to detach from the temperature measuring ring 11. At this time, the temperature measuring ring 11 loses its circumferential restraint on the sliding rod 12. The spring between the outer sleeve 10 and the charging box 4 drives the outer sleeve 10 to move to the right. The outer sleeve 10 squeezes and drives the limiting block 16 to move away from the axis of the outer sleeve 10. The limiting block 16 squeezes the adjacent limiting groove 14 through the limiting rod 15, thereby causing the rotating frame 13 and the sliding rod 12 to rotate together. At this time, the sliding rod 12 slides in the adjacent arc-shaped groove on the temperature measuring ring 11 until the limiting block 16 loses its restraint. The spring between the outer sleeve 10 and the charging box 4 causes the adapter 5 to move to the right and be pulled out of the charging box 4 until the adapter 5 moves to the right side of the rotating frame 13. At this time, the adapter 5 falls down under the action of gravity, thus losing contact with the charging box 4. Through the rapid physical disconnection mechanism, the connection between the cable and the pile can be actively cut off in the event of a fire, thus constructing a key passive safety line. This effectively prevents the open flame from spreading along the cable to the vehicle, greatly reducing the risk of secondary disasters such as "fire spreading to multiple buildings", and providing crucial protection for the safety of personnel and property. After the problem is solved, professionals go to inspect and control the parts on the charging box 4 to reset.

[0027] Example 2 This embodiment discloses a ceiling-mounted charging pile with active obstacle avoidance function, which is a further improvement on the basis of embodiment 1.

[0028] The structure, connection relationship and working process of the charging pile in Example 1 will not be described again. The working principle of the following structure will be explained in detail.

[0029] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes a winding frame 19, which consists of two mirror-distributed circular rings and several circumferentially arrayed arc-shaped plates. The winding frame 19 is rotatably connected to the fixed frame 103. Circumferentially arrayed dispersing rods 20 are rotatably connected to the winding frame 19. The circumferentially arrayed dispersing rods 20 and the circumferentially arrayed arc-shaped plates of the winding frame 19 are staggered. The charging cable 51 is wound around the winding frame 19, and the dispersing rods 20 are provided with evenly distributed... The protrusion 21 has a cylinder 22 rotatably connected to the fixing frame 103 and fixed to the winding frame 19. A fixing rod 23 is fixed to the fixing frame 103. A fixing toothed ring 24 is fixed to the right end of the fixing rod 23. The winding frame 19 is rotatably connected to the fixing toothed ring 24. A drive gear 25 that meshes with the fixing toothed ring 24 is fixed to the right end of the dispersing rod 20. An external power source is provided on the fixing frame 103 near the cylinder 22 to drive the cylinder 22 to rotate (not shown in the figure).

[0030] like Figure 2 , Figure 8 and Figure 9 As shown, a fixed housing 26 is fixedly connected to the fixed frame 103 via a mounting bracket. Two scraping rings 27, which are distributed in a mirror image, are fixedly connected to the fixed housing 26. The scraping rings 27 are made of elastic material and are slidably connected to the charging cable 51. They are used to clean impurities and foreign objects from the surface of the charging cable 51. An mounting ring 28 is fixedly connected to the lower side of the charging gun 6 via a mounting rod. A limiting sleeve 29 is fixedly connected to the mounting ring 28. The limiting sleeve 29 is used to limit the lowest point of the charging cable 51. The limiting sleeve 29 is always located on the lower side of the charging gun 6.

[0031] The working process of the charging pile in this embodiment is as follows: During the process of releasing the charging cable 51, the user drives the cylinder 22 to rotate using external power. The cylinder 22 drives the winding frame 19 and its parts to rotate together. During the rotation, the winding frame 19 gradually releases the charging cable 51 wound on it until the length of the charging cable 51 is sufficient (so that the charging gun 6 can be plugged into the car charging port). Then the cylinder 22 stops rotating and charging begins. At this time, under the restriction of the mounting ring 28, the lowest point of the charging cable 51 must be lower than the interface between the charging gun 6 and the car to prevent water from leaking from the roof or flowing along the charging cable 51 to the interface during the humid season in the south, thus ensuring charging safety.

[0032] After the car is fully charged, the user controls the retractable end of the multi-stage telescopic rod 2 to retract. Simultaneously, the user controls external power to drive the cylinder 22 to rotate in the opposite direction. The cylinder 22 drives the winding frame 19 and its components to rotate in the same direction. As the winding frame 19 continues to rotate in the opposite direction, it gradually re-gathers the charging cable 51. During the winding process, the winding frame 19 drives all the dispersing rods 20 to rotate circumferentially. The dispersing rods 20 drive the drive gear 25 on them to rotate circumferentially. During the rotation, the drive gear 25 meshes with the fixed gear ring 24 and drives the dispersing rods 20 to rotate. The dispersing rods 20 drive the evenly distributed protrusions 21 on them to rotate. During the rotation, the protrusions 21 continuously rotate the charging cable being wound. The cable 51 vibrates, thereby releasing the internal stress generated during the twisting and coiling process, allowing each part of the charging cable 51 to "reset" and become loose, making it easier to straighten and coil (the same applies to the release process of the charging cable 51, and the vibration applied during the release process can prevent the outer ring of the charging cable 5 from tightening and locking, keeping it in a relatively loose structure and achieving smooth release), thus improving the service life of the charging cable 5. During the coiling process of the charging cable 5, the two scraping rings 27 work together to clean the debris attached to the cable, preventing the debris on the cable surface from affecting the cable after coiling (such as hard debris damaging the charging cable 5 under pressure).

[0033] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
