Description

Technical Field

[0001] This invention relates to the field of AC charging pile technology, and in particular to a side-maintenance AC charging pile structure. Background Technology

[0002] An AC charging station is a device in an electric vehicle (EV) charging system, primarily used to provide AC power to charge the battery of an electric vehicle. Unlike a DC charging station, an AC charging station converts AC power from the mains into the electrical energy required by the electric vehicle, typically through an onboard charger.

[0003] The prior art publication CN106985686A discloses a novel vertical dual-gun AC charging pile. This technology employs a dual-design lightning protection system, adding a discharge tube to the existing surge protector for double lightning protection. This improves the lightning protection performance and electromagnetic compatibility of the charging pile system, ensuring safe and stable operation and preventing equipment damage and personal injury accidents. Furthermore, it features dual current protection functions: circuit breaker short-circuit protection and overcurrent detection protection circuits. It also includes a grounding detection circuit, which will issue a grounding fault warning when the ground wire is missing or open, maximizing the safety of people and vehicles and ensuring the reliability of the AC charging pile system.

[0004] In the current technology, maintenance personnel need to stand or squat to operate during maintenance. However, the current technology is not convenient to provide maintenance personnel with the technology to operate while sitting. Standing or squatting for a long time can easily lead to physical fatigue. Due to physical discomfort, the maintenance personnel's attention and operating accuracy may decrease, thereby affecting work efficiency and extending the maintenance work time.

[0005] In summary, the existing technology lacks a technology that allows for seated operation when maintaining the side of an AC charging station. Summary of the Invention

[0012] Preferably, a tension plate is fixedly connected to the bottom of the elastic storage bag, and two connecting rod groups are rotatably connected on both sides of the tension plate in a symmetrical structure. The other end of the connecting rod group is rotatably connected to the inner wall of the seatable side plate, and a gear shaft is fixedly connected between the two connecting rod groups on one side.

[0013] Preferably, a transmission rack is meshed on one side of the gear shaft, and a T-shaped slide rod is fixedly connected to one end of the transmission rack. The T-shaped slide rod is slidably engaged with the inner wall of the seatable side plate. A spring is fixedly connected to one side of the T-shaped slide rod, and the other end of the spring is fixedly connected to the inner wall of the seatable side plate. An inclined rod is fixedly connected to the other side of the T-shaped slide rod, and the inclined surface of the inclined rod is slidably in contact with one end of the support frame.

This can effectively protect the equipment from external environmental factors when the charging pile is maintained outdoors, while providing a safer and more comfortable working environment for maintenance personnel. This not only improves maintenance efficiency but also extends the service life of the equipment, enhances user experience, and improves the overall reliability of the equipment.

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The AC charging pile structure shown includes a charging pile shell 1, a component rack 2 slidably fitted inside the charging pile shell 1, transmission rods 3 rotatably connected to the inner walls on both sides of the charging pile shell 1, a seatable side plate 4 rotatably connected to the side opening of the charging pile shell 1, a support frame 5 rotatably connected to the inner wall of one end of the seatable side plate 4, an elastic storage bag 6 fixedly connected to the middle of the seatable side plate 4, a fixing frame 7 fixedly connected to the outer wall of the side of the charging pile shell 1, and a maintenance shielding mechanism 8 rotatably connected to the fixing frame 7.

[0031] like Figure 3As shown, a hydraulic rod 201 is fixedly connected to the inner wall of the bottom end of the component rack 2. One end of the hydraulic rod 201 is fixedly connected to the inner wall of the charging pile housing 1. Slide seats 202 are fixedly connected to both sides of the bottom end of the component rack 2. Two rollers 203 are symmetrically connected to the slide seats 202 and slide in contact with the inner wall of the charging pile housing 1. A transmission guide head 204 is fixedly connected to the inner wall of the slide seats 202. By allowing the component rack 2 to be pushed out of the charging pile housing 1 for maintenance, not only is the maintainability and efficiency of the equipment improved, but the operating experience of maintenance personnel is also enhanced. The overall design improves the durability of the equipment, reduces the frequency of failures, and significantly reduces maintenance costs. Most importantly, it extends the service life of the equipment and increases user satisfaction, contributing to the long-term stable operation of the charging pile. The component rack 2 is moved by the hydraulic rod 201, so that the component rack 2 is moved out of the charging pile shell 1 for easy maintenance. At this time, the transmission guide 204 in the slide 202 at the bottom of the component rack 2 will slide in the transmission groove 301 on the transmission rod 3, which will drive the transmission rod 3 to rotate.

[0032] like Figure 4 As shown, a transmission groove 301 is formed on the outer wall of the transmission rod 3. One end of the transmission groove 301 is spirally arranged, and the other end is straight. The inner wall of the transmission groove 301 is slidably fitted with the outer wall of the transmission guide head 204. A drive wheel 302 is fixedly connected to one end of the transmission rod 3. The transmission rod 3 drives the connected drive wheel 302 to rotate, and then the drive wheel 302 can drive the seatable side plate 4 connected to the driven wheel 401 to rotate and flatten.

[0033] like Figure 5 As shown, driven wheels 401 are fixedly connected to both sides of one end of the seatable side plate 4. The driven wheels 401 are meshed with the driving wheels 302 for transmission. A placement opening 402 is provided through the middle of the seatable side plate 4.

[0034] like Figure 6 As shown, an adjusting wheel 501 is fixedly connected to one end of the support frame 5. An adjusting rack 502 is engaged with one side of the adjusting wheel 501. A threaded rod 503 is threadedly connected to one end of the adjusting rack 502. The threaded rod 503 is rotatably connected to the inner wall of the seatable side plate 4. A universal joint 504 is fixedly connected to the other end of the threaded rod 503. The other end of the universal joint 504 extends through the inner wall of the seatable side plate 4 to the outside and is fixedly connected to a transmission wheel 505. An arc-shaped rack 506 is engaged with one side of the transmission wheel 505. The arc-shaped rack 506 is fixedly connected to the inner wall of the charging pile housing 1. Under the action of the arc-shaped rack 506, the transmission wheel 505, which meshes with it, will rotate. This will cause the transmission wheel 505 to drive the threaded rod 503 connected to the universal joint 504 to rotate, and the threaded rod 503 will drive the adjusting rack 502 to move. At this time, the adjusting rack 502 can drive the support frame 5 connected to the adjusting wheel 501 to rotate 90 degrees.

[0035] like Figure 7 As shown, a tension plate 601 is fixedly connected to the bottom of the elastic storage bag 6. Two connecting rod assemblies 602 are rotatably connected on both sides of the tension plate 601 in a symmetrical structure. The other end of the connecting rod assembly 602 is rotatably connected to the inner wall of the seatable side plate 4. A gear shaft 603 is fixedly connected between the two connecting rod assemblies 602 on one side. The elastic storage bag 6 is made of rubber material.

[0036] A transmission rack 604 is meshed on one side of the gear shaft 603. A T-shaped slide rod 605 is fixedly connected to one end of the transmission rack 604. The T-shaped slide rod 605 is slidably engaged with the inner wall of the seatable side plate 4. A spring 606 is fixedly connected to one side of the T-shaped slide rod 605. The other end of the spring 606 is fixedly connected to the inner wall of the seatable side plate 4. An inclined rod 607 is fixedly connected to the other side of the T-shaped slide rod 605. The inclined surface of the inclined rod 607 is in slidable contact with one end of the support frame 5. After the support frame 5 rotates, the inclined rod 607 in contact with it is unrestricted and will drive the T-shaped slide rod 605 to move under the action of the spring 606. This allows the transmission rack 604 on the T-shaped slide rod 605 to drive the gear shaft 603 to rotate. At this time, the gear shaft 603 will drive the connected linkage group 602 to rotate, so that the linkage group 602 can drive the stretching plate 601 to move downward, stretching the elastic storage bag 6 downward.

[0037] like Figure 8 As shown, the maintenance shielding mechanism 8 includes a rotating frame 801, which is rotatably connected to the fixed frame 7. A motor 802 is fixedly connected to one end of the rotating frame 801, and the motor 802 is fixedly connected to the fixed frame 7. Two tension rods 803 are rotatably connected to the rotating frame 801 in a symmetrical structure.

[0038] An elastic curtain 804 is fixedly connected between two tension rods 803. One end of the elastic curtain 804 is fixedly connected to a rotating frame 801. A gear 805 is fixedly connected to the end of the tension rod 803 connected to the rotating frame 801. A ring gear 806 is engaged with one side of the gear 805, and the ring gear 806 is fixedly connected to a fixed frame 7. A motor 802 drives the rotating frame 801 to rotate. Under the action of the ring gear 806, the engaged gear 805 rotates, which in turn drives the tension rods 803 to rotate, allowing the two tension rods 803 to stretch and unfold the elastic curtain 804. The elastic curtain 804 is made of rubber.

[0039] Working principle: When maintenance of the charging pile is required, the motor 802 first drives the connected rotating frame 801 to rotate. At this time, under the action of the ring gear 806, the meshing gear 805 will rotate. Then, the gear 805 will drive the connected tension rod 803 to rotate, so that the two tension rods 803 can stretch and unfold the connected elastic curtain 804 to block the top. When the rotating frame 801 rotates to about 90 degrees, it stops rotating. At this time, the elastic curtain 804 will be in an inclined state, which is convenient for rainwater to be diverted in rainy weather.

[0040] Then, the hydraulic rod 201 is used to move the component rack 2, so that the component rack 2 is moved out of the charging pile housing 1 for easy maintenance. At this time, the transmission guide head 204 in the slide 202 at the bottom of the component rack 2 will slide in the transmission groove 301 on the transmission rod 3. This will drive the transmission rod 3 to rotate, so that the transmission rod 3 drives the connected drive wheel 302 to rotate. Then the drive wheel 302 can drive the seatable side plate 4 connected to the driven wheel 401 to rotate and flatten.

[0041] Meanwhile, before the seatable side plate 4 is rotated and laid flat, the transmission wheel 505 meshing with it will rotate under the action of the arc rack 506, so that the transmission wheel 505 can drive the threaded rod 503 connected to the universal joint 504 to rotate, so that the threaded rod 503 can drive the adjusting rack 502 to move. At this time, the adjusting rack 502 can drive the support frame 5 connected to the adjusting wheel 501 to rotate 90 degrees. Then, after the seatable side plate 4 is rotated and laid flat, the support frame 5 can support it.

[0042] Meanwhile, after the support frame 5 rotates, the inclined rod 607 in contact with it is unrestricted. Under the action of the spring 606, it will drive the T-shaped slide rod 605 to move, so that the transmission rack 604 on the T-shaped slide rod 605 can drive the gear shaft 603 to rotate. At this time, the gear shaft 603 will drive the connected linkage group 602 to rotate, so that the linkage group 602 can drive the stretching plate 601 to move down and stretch the elastic storage bag 6 downward.

[0043] Then, the maintenance personnel can sit on the seatable side panel 4 and place their maintenance tools and other equipment into the elastic storage bag 6 for maintenance.
