Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and specifically to a garage wall-mounted electric vehicle charging pile. Background Technology

[0002] Wall-mounted electric vehicle charging stations are devices installed on walls to replenish the power of electric vehicles. Their biggest feature is their compact structure and space-saving design, making them especially suitable for family garages or underground parking lots with limited parking space. The structure of a wall-mounted electric vehicle charging station includes a charging pile body and a mechanical structure. The charging pile body includes a shell, a charging gun, cables, and a cable winding mechanism. The mechanical structure includes a wall-mounting mounting plate and a wall-mounting bracket. The shell is usually fixedly mounted on the wall-mounting mounting plate, which is fixedly connected to the wall-mounting bracket. The wall-mounting bracket is fixed to the wall with wall nails to support the entire structure. The shell houses an electrical module, related call devices, a charging gun, and cables. The cables are electrically connected to an external power source. Power is delivered to the charging gun through the control of the electrical module. After the charging gun is inserted into the electric vehicle, it charges the electric vehicle. However, existing wall-mounted charging stations have some drawbacks, such as: In underground parking garages, gasoline cars or electric vehicles that do not need to be charged will park in charging spaces. These vehicles occupy the charging piles but do not charge. On the contrary, electric vehicles that need to be charged cannot park in the charging spaces. Since wall-mounted charging piles cannot be moved, the location of the charging piles cannot be adapted to the parking positions of electric vehicles, making the charging piles inconvenient to use. Upon searching, we found an invention patent with authorization announcement number CN119037202B, application publication date of 2024.11.29, and patent name "A Mobile Charging Pile with Position Adjustment Function". This patent is a mobile charging pile that can adjust the position of the charging pile according to the position of the electric vehicle, and multiple charging piles can move without interfering with each other. However, this charging pile technology is applied to the roof of a parking lot, rather than installed on a wall. Therefore, there is a lack of wall-mounted charging stations in the existing technology that can be installed on a wall and moved in position.

[0003] Therefore, the present invention provides a garage wall-mounted electric vehicle charging station to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a garage wall-mounted electric vehicle charging pile to solve the problem that the existing wall-mounted charging piles cannot be adapted to the location of the charging vehicle.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A garage wall-mounted electric vehicle charging station includes a mounting frame, a wall-mounted charging station, and a lifter; There are four sets of mounting brackets. Two sets of mounting brackets are fixed side by side on the external wall at the same height. The other two sets of mounting brackets are fixedly connected by connecting brackets and move up and down between the two fixed mounting brackets. The two movable mounting brackets alternately dock with the two fixed mounting brackets. A slide groove is provided between the sides of the two movable mounting brackets and the connecting bracket. A slider moves up and down in the slide groove. The other end of the slider is fixedly connected to the side of the fixed mounting bracket. When the movable mounting bracket moves down to the lowest position, the slider supports the movable mounting bracket. The lifting device moves between a fixed mounting bracket and a movable mounting bracket. A wall-mounted charging pile is fixedly connected to the output end of the lifting device. The output end of the lifting device drives the wall-mounted charging pile to move up and down. A lifting slide is installed between the two fixed mounting brackets. The lifting slide is fixedly connected to the external wall. A two-stage lifting device is installed on the output shaft of the lifting slide. The two-stage lifting device drives the movable mounting bracket to move up and down and the output end of the lifting device to move up and down in stages. Laser sensors are fixedly connected to the two fixed mounting brackets at their respective ends, with the detection end of the laser sensors facing the two-stage lift. A call button is fixedly connected to the external wall. The output ends of the call button and the laser sensors are electrically connected to the external mains control center. The output end of the external mains control center is electrically connected to the input end of the lifting slide. The input end of the wall-mounted charging pile is electrically connected to the output end of the external mains control center. Through the above technical solution, the lifting device can move the wall-mounted charging pile between the fixed installation frame and the movable installation frame, thereby adjusting the position of the wall-mounted charging pile. This allows the wall-mounted charging pile to be moved behind the parking space of the electric vehicle that needs to be charged, making it convenient for the electric vehicle to charge. When the lifting slide is powered on, it drives the two-stage lifting device to perform segmented lifting. In the first stage of lifting, the two-stage lifting device drives the movable mounting frame to move up and down, and guides and limits it through the cooperation of the sliding groove and the slider. When the movable mounting frame moves down to the lowest point, it is supported by the slider, which allows the lifting device and the wall-mounted charging pile to move down together, so that another movable mounting frame is aligned with the fixed mounting frame. That is, the wall-mounted charging pile that is needed moves down, and other movable wall-mounted charging piles move horizontally normally, thus making room for the movement trajectory of other wall-mounted charging piles. In the second stage of lifting, the two-stage lifting device drives the output end of the lifting device to move up and down, thereby driving the wall-mounted charging pile to rise and fall. When other moving wall-mounted charging piles pass over the wall-mounted charging pile that is moving down, the other moving wall-mounted charging piles can move up to avoid collision between the two wall-mounted charging piles. After passing over the wall-mounted charging pile that is moving down laterally, the moving wall-mounted charging pile moves down again to return to its original moving trajectory, thus completing the work of moving up to avoid collision and moving down to return to the original trajectory. Laser sensors on two fixed mounting brackets detect the position signal of the two-stage lift in real time, which in turn detects the position of the wall-mounted charging pile. The caller receives external commands, and both transmit the signals to the external mains control center, which then controls the start, stop, and lifting direction of the lifting slide.

[0006] Preferably, the mounting frame includes an upper limiting frame, a middle sliding frame, and a lower limiting frame. The upper limiting frame, the middle sliding frame, and the lower limiting frame are fixedly connected from top to bottom. The upper limiting frame and the lower limiting frame are symmetrical. The upper edge of the upper limiting frame extends forward, and the lower edge of the lower limiting frame extends forward. A sliding channel is provided inside the middle sliding frame.

[0007] Preferably, the lifting device includes inner support rollers, a support frame, a telescopic rod, a rotating shaft, a second spring, a contact wheel, a fixed shaft, a lifting back plate, and a pile mounting plate. Two inner support rollers are rotatably mounted on the side of the support frame via a rotating shaft. The inner support rollers roll within the middle slide frame. A telescopic rod is rotatably mounted on the side of the support frame via a rotating shaft. The telescopic rod extends and retracts. The other end of the telescopic rod rotatably passes through the fixed shaft. A rotating shaft is rotatably mounted on the side of the support frame. A second spring is fixedly connected to the end of the rotating shaft. The other end of the second spring is fixedly connected to the fixed shaft. One end of the fixed shaft rotatably passes through the contact wheel. The contact wheel rolls on the upper edge of the upper limiting frame or the lower edge of the lower limiting frame. The other end of the fixed shaft is fixedly connected to the side of the lifting back plate. The pile mounting plate is fixedly connected to the side of the lifting back plate. A wall-mounted charging pile is fixedly connected to the pile mounting plate. A motor is fixedly connected inside the support frame. The input end of the motor is electrically connected to the output end of an external mains power control center, and the output end of the motor is fixedly connected to the rotation center of the inner support roller. Through the above technical solution, the extension edge structure of the upper and lower limiting frames achieves mechanical limiting of the contact wheel, fixed shaft, lifting back plate, and pile mounting plate, restricting their highest and lowest movement heights. The inner support roller rolls within the middle slide frame, providing main support force and linear guidance, supporting the up-and-down movement of the contact wheel, fixed shaft, lifting back plate, and pile mounting plate. The motor drives the inner support roller to rotate, which in turn drives the entire lifting device to move laterally. The contact wheel rolls in cooperation with the upper extension edge of the upper limiting frame or the lower extension edge of the lower limiting frame. Combined with the preload of the second spring, it ensures that there is always auxiliary support and limiting after lifting. This ensures that the contact wheel is tightly pressed against the upper extension edge of the upper limiting frame or the lower extension edge of the lower limiting frame for rolling. When the pile mounting plate moves up and down, it drives the wall-mounted charging pile to move up and down, thereby adjusting the height of the wall-mounted charging pile during movement.

[0008] Preferably, the two-stage lifting device includes a limiting rod, a limiting lifting slide, a slide output shaft mounting bracket, and a lifting pin. The slide output shaft mounting bracket is fixedly connected to the output end of the lifting slide. The lifting pin is movably inserted into the slide output shaft mounting bracket. The lifting pin is fixedly connected to the limiting lifting slide. The lower end of the limiting lifting slide is fixedly connected to the upper end of the movable mounting bracket. The limiting lifting slide is located between two limiting rods. The length of the limiting lifting slide is less than the length between the two ends of the limiting rods. The two limiting rods are fixedly connected to the upper and lower ends of the lifting back plate, respectively. The detection end of the laser sensor corresponds to the limiting rod. Through the above technical solution, the mechanical interference between the limiting rod and the limit lifting slide allows for the automatic segmented distribution of the lifting slide's output force. First, the movable mounting frame is driven to lift as a whole, and then the lifting device and the wall-mounted charging pile are driven to lift independently. No additional control mechanism is required. The sliding cooperation between the lifting pin and the slide output shaft mounting frame ensures a smooth transition between the two lifting segments.

[0009] Preferably, two fixed mounting brackets are fixedly connected to fixed cable slides. A flip-type cable slide is rotatably connected between the two fixed cable slides via a cable slide positioner. A second sliding bracket is slidably installed between the fixed cable slide and the flip-type cable slide. The cable of the wall-mounted charging pile passes through the second sliding bracket. Two baffles are fixedly connected to the pile mounting plate. The second sliding bracket is located between the two baffles. A second roller rotates inside the second sliding bracket via a pivot. The second roller rolls on the fixed cable slide and the flip-type cable slide. Two push-rotating plates are fixedly connected to the middle of the flip-type cable slide. A connecting plate is fixedly connected to the upper end of the limiting lifting slide. When the connecting plate moves up and down, it pushes the push-rotating plates to rotate the flip-type cable slide. Through the above technical solution, the pile mounting plate drives the baffle to move, and the baffle drives the second sliding bracket to move, so that the second sliding bracket can move together with the wall-mounted charging pile, and the second sliding bracket can carry the cable of the wall-mounted charging pile to follow it. By linking the limit lifting carriage with the connecting plate and the push plate, the automatic flipping and resetting of the flip-type linear carriage is realized without the need for additional power. When the wall-mounted charging pile is lowered, the flip-type cable slide causes the second sliding bracket to flip, so that the upper rails of the flip-type and fixed cable slides are unobstructed. This allows other second sliding brackets to move along the upper rails. The second sliding brackets, in conjunction with the second rollers, move on the flip-type and fixed cable slides, ensuring that the charging pile cables maintain orderly and tangle-free sliding traction during the lifting and lowering process. This prevents cables from sagging, knotting, or interfering with moving parts. The overall structure achieves synchronous linkage between lifting and lowering actions and cable management, improving cable safety and equipment cleanliness during the lifting and lowering process. It is suitable for wall-mounted charging scenarios with frequent lifting and lowering.

[0010] Preferably, the line carriage positioner includes a shaped groove, a top column, a first spring, an inner rotating column, and an outer connecting sleeve. The inner rotating column is fixedly connected to the end of the fixed line carriage, and the rotation of the inner rotating column passes through the outer connecting sleeve. The outer connecting sleeve is fixedly connected to the end of the flip-type line carriage. The outer connecting sleeve is provided with a shaped groove. The two ends of the shaped groove are arc-shaped and the middle of the two ends tapers inward, so that the distance between the two ends of the shaped groove and the center of the inner rotating column is greater than the distance between the middle and the center of the inner rotating column. Two top columns are movably inserted at one end of the inner rotating column located in the shaped groove. A first spring is fixedly connected between the top column and the inner rotating column. The first spring pushes the top column to move against the surface of the shaped groove. Through the above technical solution, by utilizing the contour of the irregular groove, which is large at both ends and small in the middle, in conjunction with the first spring and the top column, the flip-type line carriage can be opened and closed with self-locking position in the vertical state without the need for an additional locking device. When rotating, it needs to overcome the spring force through the contraction section, providing a clear stop and position holding force to prevent accidental flipping due to gravity or vibration. Furthermore, when the inner rotating column drives the top column to rotate by 90°-100°, the first spring can push the top column to rotate the inner rotating column by 180°, that is, a smaller rotation angle is required to complete the complete vertical flip of the flip-type line carriage.

[0011] Preferably, the cable of the wall-mounted charging pile passes through the cable holder and is then plugged into the external mains power control center. The cable holder includes a first sliding bracket, a first roller, and a suspension rail. The suspension rail is fixedly connected to the ceiling of the wall and faces the mounting frame. The first sliding bracket is slidably installed along the outer length of the suspension rail. There are no fewer than two first sliding brackets. The first roller rotates through a pivot inside the first sliding bracket and rolls on the suspension rail. The cable of the wall-mounted charging pile is fixedly passed through a row of first sliding brackets. The suspension rail is installed at an angle, with the height of the end of the suspension rail closer to the mounting frame being higher than the height of the end farther from the mounting frame. Through the above technical solution, the inclined suspension rail, together with the first sliding bracket and the first roller, enables the cable to automatically slide and follow the wall-mounted charging pile and be tensioned by gravity, avoiding cable accumulation or tangling. Multiple sets of first sliding brackets evenly support the cable, reducing local bending stress and extending cable life. The first roller has low rolling friction resistance and is sensitive to sliding, ensuring smooth cable retraction and extension. The overall structure does not require additional power or spring tensioning mechanism, and can automatically adjust the cable slack by gravity, improving the reliability and simplicity of cable management for lifting charging piles.

[0012] Preferably, a limiting plate is fixedly connected between the two fixedly installed mounting brackets at their close ends, with the two limiting plates facing downwards and the vertically movable mounting bracket located between the two limiting plates; With the above technical solution, when the movable mounting frame, the lifting device, and the wall-mounted charging pile move up and down under the drive of the two-stage lifting device, their sides are always constrained by two limiting plates, which restrict their displacement in the horizontal direction. At the same time, the downward extension structure of the limiting plates maintains a certain overlap and coverage throughout the entire lifting process of the movable mounting frame, preventing the movable frame from leaving the limiting area.

[0013] The beneficial effects of this invention are as follows: This device allows the lifting device to move the wall-mounted charging pile between a fixed mounting frame and a movable mounting frame, thereby adjusting the position of the wall-mounted charging pile. It can move the wall-mounted charging pile behind the parking space of the electric vehicle that needs to be charged, making it convenient for the electric vehicle to charge. It can also move the lifting device and the wall-mounted charging pile down together, while other wall-mounted charging piles are moved up and then down again, avoiding collisions and interference between two wall-mounted charging piles. It completes the work of avoiding collisions when moving up and returning to the original trajectory when moving down. In summary, this device can move the wall-mounted charging pile behind an unoccupied parking space when the charging spot is occupied by a non-charging vehicle. The location of the wall-mounted charging pile can be adapted to the parking position of the electric vehicle to be charged. The wall-mounted charging pile is more flexible and convenient to use, and will not obstruct the movement of other wall-mounted charging piles. Two adjacent wall-mounted charging piles can be used together. Attached Figure Description

[0030] The following will refer to the attached reference. Figures 1 to 15 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] As attached Figure 1 - Appendix Figure 15 As shown, a garage wall-mounted electric vehicle charging station includes a mounting frame 3, a wall-mounted charging station 4, and a lifter 13. Mounting bracket 3: See attached document Figure 1 and attached Figure 4 There are four sets of mounting brackets 3. Two sets of mounting brackets 3 are fixed to the external wall side by side by existing installation methods such as wall nails or screws. These are the fixed mounting brackets 3. The two fixed mounting brackets 3 are at the same height, so that the two sets of mounting brackets 3 are aligned left and right. See appendix Figure 1 and attached Figure 4 In addition, a connecting frame 5 is fixedly connected between the other two sets of mounting frames 3. The connecting frame 5 and the two sets of mounting frames 3 move up and down between the two sets of fixed mounting frames 3, which is the movable mounting frame 3. The two movable mounting frames 3 alternately dock with the two fixed mounting frames 3. See appendix Figure 9 and attached Figure 10A groove 20 is provided between the sides of the two movable mounting brackets 3 and the connecting bracket 5. A slider 21 slides up and down in the groove 20. The other end of the slider 21 is fixedly connected to the side of the fixed mounting bracket 3, so that when the movable mounting bracket 3 moves down to the lowest position, the slider 21 supports the movable mounting bracket 3. See appendix Figure 1 The mounting frame 3 includes an upper limiting frame 301, a middle slide 302, and a lower limiting frame 303. The upper limiting frame 301, the middle slide 302, and the lower limiting frame 303 are fixedly connected from top to bottom. The upper limiting frame 301 and the lower limiting frame 303 are symmetrical. The upper edge of the upper limiting frame 301 extends forward, and the lower edge of the lower limiting frame 303 extends forward. A sliding channel is provided inside the middle slide 302. See appendix Figure 1-7 The lifting device 13 moves between the fixed mounting bracket 3 and the movable mounting bracket 3. A wall-mounted charging pile 4 is fixedly connected to the output end of the lifting device 13. A lifting slide 1 is installed between the two fixed mounting brackets 3. The lifting slide 1 is fixedly connected to the external wall. A two-stage lifting device is installed on the output shaft of the lifting slide 1. The two-stage lifting device has two lifting actions. In the first lifting action, the two-stage lifting device drives the movable mounting bracket 3 to move up and down. In the second lifting action, the two-stage lifting device drives the output end of the lifting device 13 to move up and down. See appendix Figure 1 and 4 Laser sensors 23 are fixedly connected to the two fixed mounting brackets 3 at their respective ends, with the detection end of the laser sensor 23 facing the two-stage lift. The laser sensor 23 detects the position of the two-stage lift, the lift 13, and the wall-mounted charging pile 4. A call button 22 is fixedly connected to the external wall. The output ends of the call button 22 and the laser sensor 23 are electrically connected to the external power control center. The output end of the external power control center is electrically connected to the input end of the lifting slide 1. The call button 22 and the laser sensor 23 are used to detect the position of the wall-mounted charging pile 4 and make a call. When the wall-mounted charging pile 4 reaches the designated position, the lifting slide 1 is controlled to move the output end of the lift 13 up and down through the two-stage lift, thereby moving the wall-mounted charging pile 4 up and down. The input end of the wall-mounted charging pile 4 is electrically connected to the output end of the external power control center.

[0032] See appendix Figure 1 Appendix Figure 3 and attached Figure 7To prevent the cables on two adjacent wall-mounted charging piles 4 from getting tangled, fixed cable slides 2 are fixedly connected to both mounting brackets 3. A flip-type cable slide 11 is rotatably connected between the two fixed cable slides 2 via a cable slide locator 12. A second sliding bracket 8 is slidably installed between the fixed cable slides 2 and the flip-type cable slide 11. The cables of the wall-mounted charging piles 4 pass through the second sliding bracket 8. Two baffles 9 are fixedly connected to the lifter 13. The second sliding bracket 8 is located between the two baffles 9. A second roller 7 rotates inside the second sliding bracket 8 via a pivot. The second roller 7 rolls on the fixed cable slides 2 and the flip-type cable slide 11. Two push-rotating plates 10 are fixedly connected to the middle of the flip-type cable slide 11. A connecting plate 15 is fixedly connected to the two-stage lifter. When the connecting plate 15 moves up and down, it pushes the push-rotating plates 10 to push the flip-type cable slide 11 to rotate.

[0033] See appendix Figure 4 and attached Figure 5 Limiting plates 14 are fixedly connected between the two fixed mounting brackets 3 at their close ends. The two limiting plates 14 are set downwards, and the mounting brackets 3 that are movably installed vertically are located between the two limiting plates 14.

[0034] As attached Figure 7 Appendix Figure 11 and attached Figure 14 As shown, the lifting device 13 includes inner support rollers 1301, a support frame 1302, a telescopic rod 1303, a rotating shaft 1304, a second spring 1305, a contact wheel 1306, a fixed shaft 1307, a lifting back plate 1308, and a pile mounting plate 1309. Two inner support rollers 1301 are rotatably mounted on the side of the support frame 1302 via a rotating shaft. The inner support rollers 1301 roll within the middle slide 302. A telescopic rod 1303 is rotatably mounted on the side of the support frame 1302 via a rotating shaft. The telescopic rod 1303 extends and retracts. The other extension end of the telescopic rod 1303 rotatably passes through the fixed shaft 1307, rotating on the side of the support frame 1302. A rotating shaft 1304 is fixedly connected to a second spring 1305 at one end. The other end of the second spring 1305 is fixedly connected to a fixed shaft 1307. One end of the fixed shaft 1307 rotates through a contact wheel 1306. The contact wheel 1306 rolls on the upper edge of the upper limit frame 301 or the lower edge of the lower limit frame 303. The other end of the fixed shaft 1307 is fixedly connected to the side of the lifting back plate 1308. The side of the lifting back plate 1308 is fixedly connected to a pile mounting plate 1309. A wall-mounted charging pile 4 is fixedly connected to the pile mounting plate 1309. The lifting slide 1 is controlled to drive the lifting back plate 1308 to move up and down through a two-stage lifting device. The baffle 9 is fixedly connected to the pile mounting plate 1309; A motor 24 is fixedly connected inside the support frame 1302. The input end of the motor 24 is electrically connected to the output end of the external mains control center, and the output end of the motor 24 is fixedly connected to the rotation center of the inner support roller 1301. The working principle of the elevator 13 is as follows: After the external mains power control center controls the motor 24 to work, it drives the inner support roller 1301 to roll inside the middle slide 302 of the mounting frame 3, thereby driving the entire lifting device 13 to move laterally along the middle slide 302. When the device reaches the mounting frame 3, the external mains control center controls the lifting slide 1 to move the lifting back plate 1308 up and down through the two-stage lifting device. The telescopic rod 1303 and the second spring 1305 automatically extend and retract according to the stroke change, and drive the fixed shaft 1307 and the contact wheel 1306 to move, so that the contact wheel 1306 always rolls against the upper edge of the upper limit frame 301 or the lower edge of the lower limit frame 303. During the follow-up process, the fixed shaft 1307 drives the lifting back plate 1308 to move up and down. The lifting back plate 1308 then drives the wall-mounted charging pile 4 to move up and down synchronously through the pile mounting plate 1309.

[0035] As attached Figure 4 Appendix Figure 6 and attached Figure 7 As shown, the two-stage lifting device includes a limiting rod 16, a limiting lifting slide 17, a slide output shaft mounting bracket 18, and a lifting pin 19. The slide output shaft mounting bracket 18 is fixedly connected to the output end of the lifting slide 1. The lifting pin 19 moves up and down inside the slide output shaft mounting bracket 18. The lifting pin 19 is fixedly connected to the limiting lifting slide 17. The lower end of the limiting lifting slide 17 is fixedly connected to the upper end of the movable mounting bracket 3. The limiting lifting slide 17 is located between the two limiting rods 16. The length of the limiting lifting slide 17 is less than the length between the two ends of the limiting rods 16. The two limiting rods 16 are fixedly connected to the upper and lower ends of the lifting back plate 1308, respectively. The detection end of the laser sensor 23 corresponds to the limiting rod 16. The lower end of the connecting plate 15 is fixedly connected to the upper end of the limiting lifting slide 17. The working principle of the two-stage lifter is as follows: when the lifting slide 1 is powered on, it drives the slide output shaft mounting bracket 18 to move up and down. First stage of descent: The slide output shaft mounting bracket 18 drives the limit lifting slide 17 to descend synchronously through the lifting pin 19. The limit lifting slide 17 drives the movable mounting bracket 3 to descend until the slider 21 reaches the upper end of the slide groove 20. At this time, the slider 21 supports the movable mounting bracket 3 and no longer moves down. First stage upward movement: The slide output shaft mounting bracket 18 drives the limit lifting slide 17 to move up and down synchronously through the lifting pin 19, and the limit lifting slide 17 then drives the movable mounting bracket 3 to move up. It can be seen that both the first downward movement and the first upward movement drive the movable mounting frame 3 to move, that is, drive the lifting device 13 and the suspended charging pile 4 to move up and down. It is also worth noting that, since the length of the limiting lifting slide 17 is less than the length between the two ends of the limiting rod 16, and the limiting lifting slide 17 is located between the two ends of the limiting rod 16, when the first downward and upward movement is performed as described above, the limiting lifting slide 17 can freely pass between the two ends of the limiting rod 16 without causing the lifting back plate 1308 and the pile mounting plate 1309 of the lifting device 13 to move up and down. When the first stage of upward movement is performed, the second stage of upward movement and the second stage of downward movement will not be performed. Only after the first stage of downward movement is performed will the other lifting devices 13 be moved up and down in the second stage. That is, after the local mounting frame 3, lifting device 13 and suspended charging pile 4 are moved down, the lifting devices 13 from other positions will be moved up and down in the second stage. The second upward movement: Before the other suspended charging piles 4 move onto the movable mounting frame 3, the limiting lifting slide 17 pushes the end of the upper limiting rod 16 upward, so that the limiting rod 16 drives the lifting back plate 1308 to move upward, and the contact wheel 1306 rolls on the upper extension edge of the upper limiting frame 301, and the suspended charging pile 4 moves upward. Second stage downward movement: After the other suspended charging piles 4 leave the movable mounting frame 3, the limiting lifting slide 17 pushes the end of the lower limiting rod 16 downward, so that the limiting rod 16 drives the lifting back plate 1308 to move downward, and the contact wheel 1306 moves from the upper edge of the upper limiting frame 301 to the lower edge of the lower limiting frame 303 to roll, and the suspended charging pile 4 moves downward back to its original position.

[0036] As attached Figure 3 and attached Figure 12 As shown, the line carriage positioner 12 includes a shaped groove 1201, a top post 1202, a first spring 1203, an inner rotating post 1204, and an outer connecting sleeve 1205. The inner rotating post 1204 is fixedly connected to the end of the fixed line carriage 2. The rotation of the inner rotating post 1204 passes through the outer connecting sleeve 1205. The outer connecting sleeve 1205 is fixedly connected to the end of the flip-type line carriage 11. The outer connecting sleeve 1205 is provided with a shaped groove 1201. The two ends of the shaped groove 1201 are arc-shaped and the middle of the two ends tapers inward, so that the shaped groove 1201... The distance between the two ends of 201 and the center of the inner rotating column 1201 is greater than the distance between the middle and the center of the inner rotating column 1201. Two top columns 1202 are movably inserted at one end of the inner rotating column 1201 located in the irregular groove 1201. A first spring 1203 is fixedly connected between the top column 1202 and the inner rotating column 1201. The first spring 1203 pushes the top column 1202 to move against the surface of the irregular groove 1201. A ball rolls inside the end of the top column 1202 to reduce the friction between the top column 1202 and the irregular groove 1201. The working principle of the line carriage positioner 12 is as follows: When the flip-type line carriage 11 rotates, it drives the outer connecting sleeve 1205 to rotate around the inner rotating column 1204. The irregular groove 1201 inside the outer connecting sleeve 1205 rotates accordingly. Under the elastic force of the first spring 1203, the two top columns 1202 at the ends of the inner rotating column 1204 always abut against the inner surface of the irregular groove 1201 and move along the groove surface. Since the distance between the arc-shaped ends of the irregular groove 1201 and the center of the inner rotating column is large, and the distance between the middle contraction section and the center of the inner rotating column is small, when the top column 1202 slides through the middle contraction section, it needs to overcome the compression resistance of the first spring 1203, thus generating two obvious stable positions during the rotation process, corresponding to the flip-open position and the closed position when the top column falls into the bottom of the arc-shaped groove at both ends. When the top column is in the middle contraction section, it is in an unstable transition state. After the external force disappears, it will automatically rotate to the nearest stable position, thereby controlling the rotation of the flip-type line carriage 11.

[0037] As attached Figure 1 and attached Figure 2 As shown, the cable of the wall-mounted charging pile 4 passes through the cable holder 6 and is then plugged into the external mains control center to supply power to the wall-mounted charging pile 4. The cable holder 6 includes a first sliding bracket 601, a first roller 602, and a suspension rail 603. The suspension rail 603 is fixedly connected to the ceiling of the wall and faces the mounting frame 3. The first sliding bracket 601 is slidably installed along the outer length of the suspension rail 603. There are at least two first sliding brackets 601. The first roller 602 rotates within the first sliding bracket 601 via a pivot. 2. The cable of the wall-mounted charging pile 4 is fixedly passed through a row of first sliding brackets 601 and rolls on the suspension rail 603. In order for the first sliding brackets 601 to actively move away from the mounting frame 3 when the cable is not pulled, the suspension rail 603 is installed at an angle. The height of the end of the suspension rail 603 closer to the mounting frame 3 is higher than the height of the end away from the mounting frame 3. The horizontal reference line is set as the x-line. The suspension rail 603 is tilted at an angle α relative to the horizontal reference line x-line. When the cable is not pulled, the first sliding bracket 601 slides towards the lower end of the suspension rail 603 by gravity. The working principle of the cable bracket 6 is as follows: when the wall-mounted charging pile 4 is raised, lowered or moved, the cable drives the first sliding bracket 601 to slide along the length of the suspension rail 603. The first roller 602 inside the first sliding bracket 601 rolls on the suspension rail 603 to reduce friction. Since the suspension rail 603 is installed at an angle, the first sliding bracket 601 and the cable will automatically slide to the lower end under the action of gravity, keeping the cable in a slightly taut state.

[0038] The working principle of this device is as follows: This device is installed with the attached Figure 13As shown, each of the three movable installation racks 3 is equipped with one wall-mounted charging pile 4. Taking charging position 5 and charging position 8 as examples: The wall-mounted charging station 4 at charging position 5 can be moved to charging positions 3, 4, 5, 6 and 7 for charging. The wall-mounted charging station 4 at charging position 8 can be moved to charging positions 6, 7, 8, 9 and 10 for charging. In other words, charging positions 5 and 8 are permanent charging positions, which are the initial points of wall-mounted charging pile 4, while charging positions 6 and 7 are temporary charging positions. Electric vehicles at these positions can be charged by wall-mounted charging pile 4 at charging positions 5 and 8. When wall-mounted charging pile 4 at charging position 5 is moved to charging position 6, wall-mounted charging pile 4 at charging position 8 cannot be moved to charging position 6. When the vehicle owner is charging, he presses the call button 22. The call button 22 sends a signal to the external mains power control center. The external mains power control center controls the motor 24 to be powered on. The motor 24 drives the inner support roller 1301 to roll in the middle slide 302, which in turn drives the lifter 13 and the wall-mounted charging pile 4 to move laterally until they reach the movable mounting frame 3. At this time, the two ends of the limiting rod 16 are detected by the two laser sensors 23 at the same time, which can stop the motor 24. The external mains power control center controls the lifting slide 1 to be powered on and work. The lifting slide 1 drives the slide output shaft mounting bracket 18, the lifting pin 19 and the limiting lifting slide 17 to move down. The movable mounting bracket 3 moves down and the slider 21 slides relative to each other in the slide groove 20. When the slider 21 reaches the upper end of the slide groove 20, the slider 21 can support the movable mounting bracket 3. Then the upper movable mounting bracket 3 and the lower movable mounting bracket 3 alternately align with the fixed mounting bracket 3. At the same time, the limiting plate 14 restricts the lifting device 13 on the movable mounting bracket 3 and the wall-mounted charging pile 4 from moving and fixes the wall-mounted charging pile 4. At this time, it can be used. The following actions also occur when the mounting bracket 3, the lifting device 13, and the wall-mounted charging pile 4 are lowered: The limiting lifting slide 17 drives the connecting plate 15 to move downward, and the connecting plate 15 pushes the rotating plate 10 to rotate, causing the flip-type line slide 11 to rotate around the line slide positioner 12. The second sliding bracket 8 on the upper end of the flip-type line slide 11 rotates to face downward, while the lower end of the flip-type line slide 11 rotates to face upward, so that the upper end of the fixed line slide 2 and the lower end of the flip-type line slide 11 are flipped to face upward and aligned, so that the other second sliding brackets 8 can slide along the upper end of the fixed line slide 2 and the lower end of the flip-type line slide 11. When other wall-mounted charging piles 4 pass by, for example, when the wall-mounted charging pile 4 at charging position 5 reaches charging position 7, and the wall-mounted charging pile 4 at charging position 8 needs to pass through charging position 7 to reach charging position 6, the first laser sensor 23 detects the limiting rod 16 on the lifter 13. Then the lifting slide 1 drives the slide output shaft mounting bracket 18 to move upward, the slide output shaft mounting bracket 18 drives the limiting rod 16 to move upward, and the limiting rod 16 drives the lifting back plate 1308, the pile mounting plate 1309 and the wall-mounted charging pile 4 to move upward, so that the wall-mounted charging pile 4 is away from the wall-mounted charging pile 4 below, avoiding the two wall-mounted charging piles 4 from colliding together, so that the contact wheel 1306 rolls along the upper edge of the upper limiting frame 301. Until the wall-mounted charging pile 4 leaves the movable mounting frame 3, the second laser sensor 23 detects the limiting rod 16 on the lifter 13, then the lifting slide 1 drives the slide output shaft mounting frame 18 to move down, the slide output shaft mounting frame 18 drives the limiting rod 16 to move down, the limiting rod 16 drives the lifting back plate 1308, the pile mounting plate 1309 and the wall-mounted charging pile 4 to move down, and the contact wheel 1306 returns to the lower edge of the lower limiting frame 303 and rolls along the lower edge of the lower limiting frame 303; After the wall-mounted charging pile 4 at charging position 7 finishes charging, it needs to wait for the wall-mounted charging pile 4 at charging position 6 to finish charging. After the wall-mounted charging pile 4 at charging position 6 returns to charging position 8, the wall-mounted charging pile 4 at charging position 7 will return to position 5. This is to prevent the cables of the two wall-mounted charging piles 4 from getting tangled or knotted.
