Description

Technical Field

[0001] This application relates to the field of charging pile equipment technology, and in particular to a rail-mounted mobile charging pile. Background Technology

[0002] With the increasing popularity of electric vehicles, mobile charging stations with overhead rails have become the preferred solution for parking lot charging facilities due to their advantages such as high space utilization and ability to cover multiple parking spaces.

[0003] However, current overhead charging stations use robotic arms for automatic charging, but the robotic arms have limited working range. If a vehicle exceeds the preset parking range, the robotic arm cannot accurately connect to the charging port, resulting in charging failure. For edge parking spaces or areas not covered by the charging station track, the robotic arm is completely ineffective, and users need to repeatedly adjust the vehicle position. Once the robotic arm system malfunctions (such as sensor abnormality or joint jamming), the entire charging station becomes completely unusable. In addition, the height of traditional charging stations is not adjustable, and the charging station body or suspended cables are easily scratched by vehicles. For vehicles with high charging port positions (such as commercial vehicles), users need to stand on tiptoe to operate. Utility Model Content

[0004] To address the issues of insufficient adaptability and fixed height of robotic arms, this application provides a rail-mounted mobile charging station.

[0005] The technical solution for a rail-mounted mobile charging pile provided in this application is as follows:

[0006] A suspended rail mobile charging pile includes a suspended rail body installed on the top of a parking lot wall. The suspended rail body is slidably connected to a moving wheel. The bottom of the moving wheel is fixedly connected to a housing. The housing is provided with a lifting device assembly for controlling the raising and lowering of the charging pile and reducing collisions. The lifting device assembly is provided with an auxiliary component for selecting automatic and manual charging modes according to actual conditions.

[0007] The lifting assembly includes a charging pile body that is slidably connected to the inside of the housing. A rack that is slidably connected through the inside of the housing and drives the charging pile body to rise and fall is fixedly connected to one side of the surface of the charging pile body.

[0008] The auxiliary component includes a robotic arm that is fixedly connected to the surface of the charging pile body and realizes automatic charging. A charging gun is provided on the surface of the robotic arm at one end away from the charging pile body. A strap with plate-shaped ends is fixedly connected to one side of the surface of the robotic arm and detachably fixes the charging gun.

[0009] By adopting the above technical solution, combined with the lifting device and auxiliary components, seamless switching between automatic and manual charging modes can be achieved, adapting to standardized parking and out-of-range scenarios, improving equipment utilization. The sliding connection structure between the shell and the hanging rail, along with the dynamic height adjustment of the lifting device, avoids collisions with vehicles or walls during movement, extending the equipment's lifespan.

[0010] Preferably, an outer casing is fixedly connected to one side of the surface of the housing and slidably connected to the rack, a round shaft is rotatably connected through the inside of the outer casing, and a gear that meshes with the rack is fixedly connected to the surface of the round shaft.

[0011] By adopting the above technical solution, the rack is used to drive the charging pile body to rise and fall.

[0012] Preferably, a cable reel is fixedly connected to one side of the surface of the charging pile body, and a charging cable wound inside the cable reel and fixed to the charging gun is movably connected inside the cable reel.

[0013] By adopting the above technical solution, the automatic retractable cable reel enables automatic cable winding and unwinding, avoiding the risks of tangling, wear, or tripping, and extending the cable's lifespan.

[0014] Preferably, a fixed base is fixedly connected to one side of the surface of the robotic arm and slidably connected to one end of the strap. A first sliding groove is formed through one side of the surface of the fixed base. A toothed groove is formed on the surface of the first sliding groove. A pressing block is symmetrically slidably connected inside the first sliding groove and the toothed groove.

[0015] By adopting the above technical solution, the pressing block-tooth groove structure allows users to quickly adjust the strap length, improving operational efficiency.

[0016] Preferably, the surface of the strap is symmetrically provided with second grooves that are slidably connected to a pressing block, and a spring is fixedly connected between the inner wall of the second groove and the surface of the pressing block.

[0017] By adopting the above technical solution, the elastic reset design of spring one ensures the strap is secure, prevents the charging gun from accidentally falling off, and enhances safety in public use scenarios.

[0018] Preferably, a third sliding groove is formed on the surface of the robotic arm, and an irregular sliding rod extending to the bottom of the robotic arm is slidably connected inside the third sliding groove. A spring is fixedly connected between the inner wall of the third sliding groove and the surface of the irregular sliding rod.

[0019] By adopting the above technical solution, the irregular slider is designed to facilitate user pressing.

[0020] Preferably, a limiting block for limiting the position of the charging gun is fixedly connected to the end face of the robotic arm away from the charging pile body.

[0021] By adopting the above technical solution, the irregular sliding rod cooperates with the limiting block to prevent the charging gun from sliding or accidentally falling off, especially ensuring the reliability of the connection during manual charging.

[0022] Preferably, a geared motor is fixedly connected to one side of the surface of the housing, and the output end of the geared motor is fixed to the surface of the round shaft.

[0023] By adopting the above technical solution, the geared motor achieves automatic lifting of the charging pile through gear and rack transmission, adapting to the needs of users of different heights and avoiding the limitations of fixed height design.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By using a robotic arm and a charging gun that is detachably fixed to the robotic arm, fully automated, contactless charging is achieved for users whose parking is within the robotic arm's working range, enhancing convenience and a sense of technology. The charging gun is secured when not in use by a pressing block and an irregular sliding rod, preventing it from falling off or being accidentally damaged. For severely irregular parking (outside the robotic arm's range) or when the charging station itself is far away, the detachable charging gun allows users to manually retrieve it for charging, greatly expanding the actual usable range and avoiding the embarrassment of being unable to charge due to location issues.

[0026] 2. The rack and pinion mechanism driven by a geared motor allows for easy adjustment of the height of the charging station and charging gun, enabling users of different heights to comfortably plug and unplug the charging gun (in manual mode), reducing discomfort from bending over or tiptoeing. When not in use, the charging station can be manually raised by the user to prevent the charging station or dangling charging cable from scraping against the vehicle body when the vehicle is moving (reversing, turning), especially for taller SUVs or trucks. When raised, the charging cable and station are higher off the ground, reducing the possibility of pedestrians or vehicles tripping over the charging cable or hitting the charging station.

[0036] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0037] This application discloses a suspended rail mobile charging pile.

[0038] Reference Figure 1 A mobile charging pile with a suspended rail includes a suspended rail body 1 installed on the top of a parking lot wall. The inner wall of the suspended rail body 1 is fixedly rubbed against the rollers of the moving wheel 2. The bottom end of the moving wheel 2 is fixedly connected to the top of the housing 3 by bolts. The housing 3 is equipped with a lifting device assembly 4, which is used to control the raising and lowering of the charging pile and reduce the collision between the charging pile and the vehicle body or objects. The lifting device assembly 4 is equipped with an auxiliary component 5 on the outside, which is used to select automatic and manual charging modes according to the actual situation.

[0039] After receiving the user's submitted charging request information via internet technology, the charging system officially initiates the charging process. The charging pile moves along the overhead rail 1 to the designated parking space and near the vehicle to be charged. For users whose parking is within the working range of the robotic arm 51, the charging pile's point A camera visually recognizes that there is enough space near the charging port for the robotic arm 51 to extend, releasing its 1st, 2nd, and 3rd axes (three degrees of freedom) sequentially. The NFC card integrated into the charging gun 52 approaches the charging port cover with its built-in NFC module. The vehicle, authorized by the pre-authorized NFC key, opens the charging port cover, and the point B camera on the robotic arm 51 recognizes the charging. The system dynamically adjusts and corrects the three axes to ensure that the charging gun 52 is inserted into the corresponding interface of the charging port. The charging system detects the normal charging current and sends feedback details such as charging current, voltage, and remaining time to the user's mobile app. In cases where parking is severely irregular (outside the range of the robotic arm 51) or the charging pile itself is too far away, the length of the robotic arm 51 is insufficient for charging. The detachable charging gun 52 allows the user to manually remove the gun for charging. The charging pile itself 46 does not occupy ground space and can be expanded to meet the charging needs of different vehicle models. It eliminates the requirement of one charging pile per vehicle and fixed parking space. Fuel vehicles and new energy vehicles do not need fixed parking spaces, saving space and reducing charging costs.

[0040] Reference Figure 2 , Figure 3 The lifting assembly 4 includes a charging pile body 46 slidably connected to the interior of the housing 3. The upper surface of the charging pile body 46 is fixed to the lower surface of the rack 43. The top end of the rack 43 penetrates the top of the housing 3 and is slidably connected to the housing 3. The rack 43 is used to drive the charging pile body 46 to rise and fall, realizing the height adjustment of the charging pile body 46. The upper surface of the housing 3 is bolted to the bottom surface of the outer casing 41. The interior of the outer casing 41 is penetrated by the rack 43. The inner wall of the outer casing 41 slides against the outer surface of the rack 43. The interior of the outer casing 41 is penetrated by a round shaft 42. The inner wall of the outer casing 41 is rotatably connected to the round shaft 42. The outer surface of the round shaft 42 is connected to the gear 44. The inner side is fixed, the outer side of the gear 44 meshes with the tooth side of the rack 43, the gap between one side of the charging pile body 46 and the inner wall of the housing 3 is relatively large, the side of the charging pile body 46 with the larger gap is fixed to the mounting end of the winding reel 47, the charging cable 48 is wound inside the winding reel 47, the end of the charging cable 48 located inside the winding reel 47 is electrically connected to the charging pile body 46 for powering the electric vehicle, the end of the charging cable 48 located outside the winding reel 47 is connected to the charging gun 52, the upper surface of the housing 3 is fixed to the mounting end of the geared motor 45, and the output end of the geared motor 45 is fixed to the end of the round shaft 42 located outside the outer box 41.

[0041] Initially, the bottom end of rack 43 meshes with gear 44. Rack 43 is made of 20CrMnTi carburized steel with a hardened surface hardness of HRC58-62. Gear 44 is a powder metallurgy copper-based gear with a solid lubricant (molybdenum disulfide composite coating) impregnated on the meshing surface to ensure minimal wear after 100,000 lifting cycles. When a user needs to charge, a descent request submitted by the user on a mobile app is initiated by reduction motor 45. Reduction motor 45 drives shaft 42 to rotate, which in turn drives gear 44 to rotate. Gear 44 then moves rack 43 downward, causing the charging pile body 46 to descend. The charging pile body 46 is lowered to an ergonomic height (such as waist level). When not in use, the charging pile body 46 is raised by the user to prevent the charging pile body 46 or the hanging charging cable 48 from scraping the vehicle body when the vehicle moves (reversing, turning), especially for taller SUVs or trucks. The charging cable 48 should be a thin cable for slow charging, and the cable length is limited to 6-8 meters. The cable reel 47 is fully internal and the charging cable 48 is in the unfolded state to meet daily needs. The use of the cable reel 47 ensures that the charging cable 48 is usually at its shortest distance when the charging gun 52 is charging. The lowest point of the charging cable 48 is higher than the ground to reduce the friction on the surface of the charging cable 48.

[0042] Reference Figure 4 , Figure 5 The auxiliary component 5 includes a robotic arm 51 fixedly connected to the surface of the charging pile body 46 for automatic charging. A charging gun 52 is movably placed on the upper surface of the robotic arm 51. The charging gun 52 is located at the end of the robotic arm 51 away from the charging pile body 46. The outer side of the robotic arm 51 is fixed to one end of a strap 54. Both ends of the strap 54 are plate-shaped. The plate-shaped ends of the strap 54 are fixed to the surface of the robotic arm 51. The strap 54 is used to fix the charging gun 52 and to remove the charging gun 52 when it is loosened. The side of the robotic arm 51 away from the strap 54 and the fixed end of the robotic arm 51 is fixed to the surface of a fixed base 53. A first groove 55 is provided on one side of the surface of the fixed base 53. The first groove 55 runs through both sides of the fixed base 53. The side of the first groove 55 closest to the robotic arm 51 is... The device is provided with a toothed groove 56, which is composed of multiple grooves arranged in an array. The two ends of the first sliding groove 55 are slidably connected to two pressing blocks 58. The ends of the two pressing blocks 58 near the robotic arm 51 are located inside the toothed groove 56. The size of the groove in the toothed groove 56 is adapted to the end of the pressing block 58 inside the toothed groove 56. When the pressing block 58 is inside the toothed groove 56, the strap 54 is locked. The surface of the end of the strap 54 inside the robotic arm 51 is symmetrically provided with a second sliding groove 57. The second sliding groove 57 penetrates the interior of the strap 54. The two pressing blocks 58 slide against the inner walls of the two second sliding grooves 57 respectively. The ends of the two pressing blocks 58 inside the second sliding grooves 57 are fixed to one end of a spring 59. The other end of the spring 59 is fixed to the inner wall of the second sliding groove 57.

[0043] Under normal conditions, spring 59 is not compressed, and pressing block 58 is located inside the toothed groove 56. When the user parks correctly (within the working range of robotic arm 51), robotic arm 51 achieves fully automated, contactless charging by controlling the cameras at points A and B. The charging gun 52 is securely stored when idle through pressing block 58 and irregular sliding rod 512, preventing it from falling off or being accidentally damaged. In cases where the user parks improperly (beyond the range of robotic arm 51) or the charging pile itself is far away, the user can press both pressing blocks simultaneously. Block 58, the two pressing blocks 58 squeeze the spring 59 and move away from the inside of the tooth groove 56. At this time, the strap 54 is not restricted, allowing the user to manually take out the gun for charging, which greatly expands the actual usable range and avoids the embarrassment of not being able to charge at all due to the position problem. When the user finishes charging, he puts the charging gun 52 back on the top of the robotic arm 51. By pressing the two pressing blocks 58, the user drives the strap 54 to slide down into the inside of the first slide groove 55. When the strap 54 can no longer move, the pressing blocks 58 are released, so that the pressing blocks 58 enter the inside of the tooth groove 56 and lock the strap 54.

[0044] Reference Figure 3 , Figure 6 The robotic arm 51 has a third slide groove 511 inside, which extends through the top of the robotic arm 51, such as... Figure 6 As shown, the inner wall of the third slide groove 511 slides against the top surface of the irregular slide bar 512. The bottom end of the irregular slide bar 512 extends to the bottom surface of the robotic arm 51, which is used to facilitate the user to press the irregular slide bar 512. The bottom of the inner wall of the third slide groove 511 is fixed to the bottom end of the second spring 513. The top end of the second spring 513 is fixed to the bottom of the top end of the irregular slide bar 512. The surface of the robotic arm 51 is fixed to the surface of the limiting block 510. The limiting block 510 is set on the end face of the robotic arm 51 away from the charging pile body 46. The bottom surface of the charging gun 52 is provided with a limiting groove. The top end of the irregular slide bar 512 is located inside the limiting groove, which is used to limit the position of the connection end between the charging gun 52 and the charging cable 48.

[0045] Under normal conditions, spring 513 is in an uncompressed state, limit block 510 is located at the charging front end of charging gun 52, and irregular slide bar 512 is located at the rear end of charging gun 52 to limit the position of both ends of charging gun 52. After the user loosens the strap 54, press the irregular slide bar 512 again to make the irregular slide bar 512 leave the limiting groove of charging gun 52. The irregular slide bar 512 moves and squeezes spring 513 to deform it. An LED guide ring is provided at the handle of charging gun 52: a solid blue light indicates that the gun can be manually removed, and a flashing red light indicates that the lock has not been released. The LED guide ring is controlled by the central processing unit of this application.

[0046] Among them, the geared motor 45, the cable reel 47 and the robotic arm 51 are all existing technologies, and their structural principles will not be described in detail. The geared motor 45 is specifically a self-locking geared motor 45, such as the JGY-370 worm gear geared motor 45. The cable reel 47 can be the DYB-D series automatic telescopic cable reel from Yiyou Hengxin.

[0047] The entire charging system function is implemented through the following circuit connection and startup process: After the user submits a charging request via a mobile APP, the command is transmitted to the charging pile main controller (such as a microcontroller or PLC) via a wireless communication module (Wi-Fi / 4G); the main controller verifies the command and coordinates each subsystem: first, it triggers the hanging rail moving motor drive circuit, and controls the charging pile to accurately position itself along the track to the target parking space through encoder feedback; the A-point camera identifies the charging port space through the image processing unit, and the main controller sequentially activates the servo motor drive circuit of the three-axis robotic arm 51, releasing axes 1, 2, and 3 to the preset position; the charging gun 52 NFC module communicates with the NFC module built into the vehicle charging port cover, and the vehicle authorization system opens the cover after verifying the pre-authorized key; the B-point camera adjusts the charging port through dynamic visual recognition. The robotic arm 51 is positioned correctly, and the main controller uses closed-loop control of the three-axis motor to insert the charging gun 52 into the interface. The charging system detects the charging status through current / voltage sensors and feeds it back to the user's APP via the communication module. If the parking is not standardized or the distance is too far, the user can manually remove the gun by triggering the adjustment module of the strap 54 (pressing block 58, toothed groove 56 structure) and the motor drive circuit of the cable reel 47 to automatically unwind the cable. The lifting function is controlled by the drive circuit of the geared motor 45 to drive the shaft 42, gear 44 and rack 43. Limit switches and encoders provide position feedback. The main controller triggers the motor to rotate forward and backward according to the APP command or timer program to realize the automatic lifting of the charging pile. The power management module supplies power to each subsystem and integrates overload protection, short circuit protection and emergency stop circuit to ensure the safe operation of the system.

[0048] It should be noted that the calculation formula for spring 59 and spring 513 is: F = kx, where F is the external force on the spring, in N, k is the spring constant, in N / m, and x is the deformation of the spring, in m. This formula is used to calculate the elastic force of the alloy spring so that it can be used in this device.

[0049] The implementation principle of a rail-mounted mobile charging pile according to this application embodiment is as follows: The rail-mounted mobile charging pile body 46 is equipped with a three-axis robotic arm 51. When the user parks properly, the charging pile body 46 can be directly charged through the robotic arm 51. When the user parks improperly or the charging pile body 46 is far away, the charging gun 52 fixed on the robotic arm 51 can be disassembled. By manually pressing the pressing block 58, the pressing block 58 leaves the inside of the tooth groove 56, allowing one end of the strap 54 to slide and loosen the strap 54. Then, the user presses the irregular sliding rod 512 to make it leave the limiting groove of the charging gun 52, without limiting the charging gun 52, and manually pulls the charging gun 52 to charge the electric vehicle. The cable of the charging gun 52... By using the automatic retractable reel 47 to rewind the cable, and through the use of the robotic arm 51 and the charging gun 52 detachably fixed to the robotic arm 51, fully automated, contactless charging is achieved for users whose parking is within the working range of the robotic arm 51, enhancing convenience and a sense of technology. The charging gun 52 is secured when not in use by the pressing block 58 and the irregular sliding rod 512, preventing it from falling off or being accidentally damaged. For severely irregular parking (beyond the range of the robotic arm 51) or when the charging station itself is far away, the detachable charging gun 52 allows users to manually retrieve the gun for charging, greatly expanding the actual usable range and avoiding the embarrassment of being unable to charge due to location issues.

[0050] When a user needs to charge, the user submits a descent request on the mobile app, and the geared motor 45 drives the rack 43 to raise and lower, making it easy to adjust the height of the charging pile body 46 and the charging gun 52. Users of different heights can comfortably plug and unplug the charging gun 52 (in manual mode), reducing the discomfort of bending over or tiptoeing. When not in use, the charging pile body 46 can be manually raised by the user to prevent the charging pile body 46 or the hanging charging cable 48 from scraping the vehicle body when the vehicle is moving (reversing, turning), especially for taller SUVs or trucks. After being raised, the charging cable 48 and the charging pile body are higher off the ground, reducing the possibility of pedestrians or vehicles tripping over the charging cable 48 or hitting the charging pile body 46.

[0051] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
