DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figures 1-8 The shown structure is an AC charging pile with side maintenance, including a charging pile shell 1, a component frame 2 is slidingly provided inside the charging pile shell 1, a transmission rod 3 is rotatably connected to the inner walls of both sides of the charging pile shell 1, a sitable side panel 4 is rotatably provided at the side opening of the charging pile shell 1, a support frame 5 is rotatably provided on the inner wall of one end of the sitable side panel 4, an elastic storage bag 6 is fixedly provided in the middle of the sitable side panel 4, a fixing frame 7 is fixedly provided on the outer wall of the side of the charging pile shell 1, and a maintenance shielding mechanism 8 is rotatably provided on the fixing frame 7.

[0021] like Figure 3As shown, a hydraulic rod 201 is fixedly connected to the inner wall of the bottom end of the component frame 2. One end of the hydraulic rod 201 is fixedly connected to the inner wall of the charging pile housing 1. Slides 202 are fixedly connected on both sides of the bottom end of the component frame 2. Two rollers 203 are symmetrically arranged on the slide 202 for rotational connection. The rollers 203 are in sliding 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 202. By allowing the component frame 2 to be pushed out from the charging pile housing 1 for maintenance, not only the maintainability and maintenance efficiency of the equipment are improved, but also the operating experience of the maintenance personnel is improved. The overall design improves the durability of the equipment, reduces the frequency of failures, and significantly reduces maintenance costs. Most importantly, it improves the service life of the equipment and user satisfaction, which contributes to the long-term stable operation of the charging pile. The hydraulic rod 201 is used to drive the component rack 2 to move 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 end 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.

[0022] like Figure 4 As shown, a transmission groove 301 is defined on the outer wall of the transmission rod 3. The transmission groove 301 has a spiral structure at one end and a linear structure at the other end. The inner wall of the transmission groove 301 is slidably engaged with the outer wall of the transmission guide head 204. A driving wheel 302 is fixedly connected to one end of the transmission rod 3. The transmission rod 3 drives the connected driving wheel 302 to rotate, which in turn drives the seatable side panel 4 connected to the driven wheel 401 to rotate and level.

[0023] like Figure 5 As shown, driven wheels 401 are fixedly connected to both sides of one end of the sitting side plate 4, and the driven wheels 401 are meshed with the driving wheel 302 for transmission. A placement opening 402 is opened through the middle of the sitting side plate 4.

[0024] like Figure 6 As shown, an adjustment wheel 501 is fixedly connected to one end of the support frame 5. An adjustment rack 502 is meshed and driven on one side of the adjustment wheel 501. A threaded rod 503 is threadedly connected to one end of the adjustment rack 502. The threaded rod 503 is rotatably connected to the inner wall of the seatable side panel 4. The other end of the threaded rod 503 is fixedly connected to a universal joint 504. The other end of the universal joint 504 extends through the inner wall of the seatable side panel 4 to the outside and is fixedly connected to a transmission wheel 505. An arc-shaped rack 506 is meshed and driven on 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 meshed with it rotates, causing the transmission wheel 505 to rotate, causing the transmission wheel 505 to drive the threaded rod 503 connected to the universal joint 504 to rotate, causing the threaded rod 503 to drive the adjustment rack 502 to move. At this time, the adjustment rack 502 can drive the support frame 5 connected to the adjustment wheel 501 to rotate 90 degrees.

[0025] like Figure 7 As shown, the bottom end of the elastic storage bag 6 is fixedly connected to a stretch plate 601. Two connecting rods 602 are symmetrically connected on both sides of the stretch plate 601 and are rotatably connected. The other ends of the connecting rods 602 are rotatably connected to the inner wall of the seatable side panel 4. A gear shaft 603 is fixedly connected between the two connecting rods 602 on one side. The elastic storage bag 6 is made of rubber material.

[0026] A transmission rack 604 is provided on one side of the gear shaft 603 for meshing transmission. One end of the transmission rack 604 is fixedly connected to a T-shaped slide bar 605. The T-shaped slide bar 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 bar 605. The other end of the spring 606 is fixedly connected to the inner wall of the seatable side plate 4. The other end of the T-shaped slide bar 605 is fixedly connected to an inclined rod 607. The inclined surface of the inclined rod 607 is slidably engaged with one end of the support frame 5. After the support frame 5 rotates, the inclined rod 607 in contact with it is unrestricted. Under the action of the spring 606, the T-shaped slide bar 605 is driven to move, so that the transmission rack 604 on the T-shaped slide bar 605 can drive the gear shaft 603 to rotate. At this time, the gear shaft 603 drives the connected connecting rod assembly 602 to rotate, so that the connecting rod assembly 602 can drive the stretching plate 601 to move downward, stretching the elastic storage bag 6 downward.

[0027] 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 stretching rods 803 are rotatably connected on the rotating frame 801 in a symmetrical structure.

[0028] An elastic barrier curtain 804 is fixedly connected between the two stretching rods 803. One end of the elastic barrier curtain 804 is fixedly connected to the rotating frame 801. A gear 805 is fixedly connected to the end of the stretching rod 803 connected to the rotating frame 801. One side of the gear 805 is meshed with a ring gear 806, which is fixedly connected to the fixed frame 7. The rotating frame 801 is rotated by the motor 802. The ring gear 806 rotates the meshed gear 805, which in turn rotates the connected stretching rods 803. This allows the two stretching rods 803 to stretch and unfold the elastic barrier curtain 804. The elastic barrier curtain 804 is made of rubber.

[0029] Working principle: When the charging pile needs to be maintained, the motor 802 is first used to drive the connected rotating frame 801 to rotate. At this time, under the action of the annular gear plate 806, the meshing gear 805 is rotated, and then the gear 805 drives the connected stretching rod 803 to rotate, so that the two stretching rods 803 can stretch and unfold the connected elastic curtain 804 to block the upper part. When the rotating frame 801 rotates nearly 90 degrees, it stops rotating. At this time, the elastic curtain 804 is in a tilted state, which is convenient for diverting rainwater on rainy days; Then, the hydraulic rod 201 is used to drive the component rack 2 to move, 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 end 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, so that the transmission rod 3 drives the connected driving wheel 302 to rotate, and then the driving wheel 302 can drive the seatable side plate 4 connected to the driven wheel 401 to rotate and level; At the same time, before the seatable side panel 4 is rotated and laid flat, the arc-shaped rack 506 causes the transmission wheel 505 meshing therewith to rotate, 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 adjustment rack 502 to move. At this time, the adjustment rack 502 can drive the support frame 5 connected to the adjustment wheel 501 to rotate 90 degrees. Then, after the seatable side panel 4 is rotated and laid flat, the support frame 5 can support it. At the same time, after the support frame 5 rotates, the inclined rod 607 in contact with it is not restricted. Under the action of the spring 606, the T-shaped slide bar 605 is driven to move, so that the transmission rack 604 on the T-shaped slide bar 605 can drive the gear shaft 603 to rotate. At this time, the gear shaft 603 drives the connected connecting rod group 602 to rotate, so that the connecting rod group 602 can drive the stretching plate 601 to move downward, stretching the elastic storage bag 6 downward; The maintenance personnel can then sit on the seatable side panel 4 and place the maintenance tools and the like into the elastic storage bag 6 for maintenance.
