Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a shared hanging charging pile for new energy vehicles. Background Art

[0002] Against the backdrop of global efforts to promote energy conservation, emission reduction, and sustainable development, the new energy vehicle industry is experiencing rapid growth. As essential infrastructure for new energy vehicles, the construction and optimization of charging stations are crucial. With urban space resources becoming increasingly scarce, suspended charging stations are gaining popularity to improve space utilization.

[0003] In the existing technology, the hanging charging piles covered by patent publication number CN118683376B, for example, while addressing the space requirements to some extent, have numerous limitations in practical application. Due to the diverse range of new energy vehicle brands and models, the locations of charging ports vary significantly across different models, with charging ports located in various locations, such as the front, rear, and side of the vehicle. Existing fixed-position hanging charging piles, however, lack the flexibility to adapt to the varying locations of charging ports across various vehicle models. This forces users to precisely position their vehicles to align the charging port with the charging pile when charging. This process requires high parking precision, increasing parking difficulty and time costs. Furthermore, because the charging piles are fixed, users often have to forcefully pull out the long charging cable to connect the charging port to the charging pile when the distance between the charging port and the charging pile is large. This operation not only consumes user energy, but the frequent and forceful pulling of the charging cable can easily damage the cable's internal structure, accelerating its aging and wear. Furthermore, long charging cables are prone to tangling and bending during daily use and management, further increasing the complexity and difficulty of maintenance. This makes charging pile maintenance costs high, and the maintenance work is tedious and time-consuming, seriously affecting the efficiency and user experience of charging piles, making it difficult to meet the diverse charging needs brought about by the rapid development of new energy vehicles. Therefore, it is urgent to develop a shared hanging charging pile for new energy vehicles that can flexibly adapt to the location of charging ports of different models, is convenient for users to operate, and is easy to maintain. Summary of the Invention

[0004] In response to the defects in the existing technology, the present invention provides a shared suspended charging pile for new energy vehicles, which solves the problems of the existing suspended charging piles being fixed in position, resulting in different models of vehicles needing specific parking directions for charging, laborious cable pulling, and the cables being easily worn and difficult to maintain.

[0007] Preferably, the two lateral movement mechanisms each include two connecting frames, two stabilizing slide bars are fixedly arranged between the two connecting frames, a sliding seat is slidingly arranged between the outsides of the two stabilizing slide bars, an oil tank is fixedly arranged inside one of the two connecting frames, an oil pump is fixedly arranged on the upper end of the oil tank, a telescopic oil cylinder is fixedly arranged on the output end of the oil pump, a connecting block is fixedly arranged on the upper end of the sliding seat, and one end of the telescopic oil cylinder is fixedly connected to the connecting block.

[0008] Preferably, the longitudinal movement mechanism includes two stable slide rails, a lower reinforcement frame is fixedly provided at the lower end of the two stable slide rails, and a connecting seat is fixedly provided near both sides between the two stable slide rails.

[0009] Preferably, two first bearing seats are fixedly provided at the upper end of the support base near both sides, a first rotating shaft is fixedly provided between each of the four first bearing seats, and power rollers are fixedly provided at both ends of the two first rotating shafts.

[0010] Preferably, roller grooves are provided inside the support base near the positions of the four power rollers, and the four power rollers respectively pass through the four roller grooves and are rolled on the inner upper ends of the two connecting seats.

[0011] Preferably, the two first rotating shafts are fixedly sleeved with a second bevel gear near one end, the upper end of the support base is fixedly provided with a second bearing seat near the position of the two second bevel gears, a second transmission shaft is fixedly connected between the two second bearing seats, and first bevel gears are fixedly provided at both ends of the second transmission shaft, and the two first bevel gears are respectively meshed with the two second bevel gears, and the meshing directions are opposite.

[0012] Preferably, a driven gear is fixedly provided on the shaft body of the second transmission shaft, a servo motor is fixedly provided on the upper end of the support base near the driven gear, a power gear is fixedly provided on the output end of the servo motor, and the power gear is meshed with the driven gear.

[0013] Working Principle: As the user moves the charging cable toward the vehicle's charging port, the charging cable deflects within the lifting frame. This deflection compresses the support pad in contact with the charging cable. Connected to the back of the support pad is a telescopic rod, which houses a movable block and an internal support spring. When the support pad is compressed, the internal support spring compresses, pushing the movable block to slide within the rod. The movement of the movable block acts on a pressure sensor within the rod. The pressure sensor accurately senses pressure changes and transmits the increased pressure signal to the control system in real time. Based on this signal, the control system calculates and analyzes it and rapidly issues commands to drive the servo motor and oil pump according to predefined control logic. The servo motor and oil pump, respectively, operate the longitudinal and transverse movement mechanisms, driving the charging mechanism to move synchronously in the direction of the charging cable's movement. This allows the charging mechanism to follow the movement of the charging cable as the user pulls it, maintaining a relatively close distance to the cable. This reduces stress and strain on the charging cable, facilitating user operation while effectively protecting the cable and ensuring a safe, stable, and efficient charging process.

[0014] The beneficial effects of the present invention are embodied in:

[0015] 1. The present invention provides a shared hanging charging pile for new energy vehicles, which is internally provided with a lateral moving mechanism, a longitudinal moving mechanism and a flexibly movable charging mechanism. Through this design, the charging pile can accurately and flexibly adjust its position in a two-dimensional plane according to the specific position of the charging port of different new energy vehicles. In actual charging scenarios, users no longer need to painstakingly adjust the parking direction and position of the vehicle to accommodate the fixed position of the charging pile. They only need to start the moving mechanism of the charging pile to conveniently move the charging mechanism directly above the vehicle charging port. This improvement makes the insertion operation of the charging gun easy and simple, greatly saving the user's time and energy, significantly improving the fluency and convenience of the charging process, effectively solving the operational problems brought to users by traditional fixed-position charging piles, and providing users with a more humane and efficient charging experience.

[0016] 2. The present invention provides a shared suspended charging pile for new energy vehicles. During the charging process, when a user holds the charging gun and moves it toward the vehicle's charging port, the charging cable will deflect within the lifting frame. This deflection of the charging cable will squeeze the support pads in different directions. After being squeezed, the support pads further compress the internal support springs and push the movable block to move. This series of actions ultimately acts on the corresponding pressure sensor. The pressure sensor can accurately capture the signal of increasing pressure and quickly feed it back to the control system. Upon receiving the signal, the control system immediately drives the servo motor and oil pump to work together, thereby driving the charging mechanism to move synchronously in the direction of the charging gun. This intelligent follow-up control method effectively prevents the charging cable from being subjected to excessive tension and friction due to strong pulling, fundamentally reducing the probability of damage such as cable surface wear and internal wire breakage, thereby significantly extending the service life of the charging cable and reducing the cost of frequent replacement due to cable damage. It also reduces the frequency and difficulty of maintenance work, thereby improving the overall reliability and stability of the charging pile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0029] like Figure 1-3As shown, an embodiment of the present invention provides a shared suspended charging pile for new energy vehicles, including two lateral moving mechanisms 2, the lower ends of the two lateral moving mechanisms 2 are fixedly provided with longitudinal moving mechanisms 3, and the upper end of the longitudinal moving mechanisms 3 is internally provided with a charging mechanism 1 that is rollingly provided. The charging mechanism 1 includes a support base 102, the upper end of the support base 102 is fixedly provided with an upper cover plate 101, the lower end of the support base 102 is fixedly provided with an electric lifting frame 104, and one side of the electric lifting frame 104 is fixedly provided with an input cable 106, which is connected to the mains power.

[0030] Specifically, in the above-mentioned specific embodiment, the lateral moving mechanism 2, the longitudinal moving mechanism 3 and the charging mechanism 1 constitute the basic structure of the charging pile. The lateral moving mechanism 2 provides the left and right movement function, the longitudinal moving mechanism 3 realizes the front and back movement, and the charging mechanism 1 carries the specific charging functional components. The electric lifting frame 104 can be lifted and lowered in the vertical direction, and its power generally comes from a common lifting drive method such as a motor-driven screw nut mechanism or a hydraulic drive. The input cable 106 introduces electricity from the mains to provide power support for the entire charging system. This multi-level mobile structure design enables the charging mechanism 1 to flexibly adjust its position in the horizontal and longitudinal directions and vertical directions of the two-dimensional plane, greatly improving the applicability of the charging pile and meeting the charging needs of different models and different parking positions. The setting of the electric lifting frame 104 makes it convenient for users to pick up the charging gun 109 at a suitable height, thereby improving the convenience and comfort of use.

[0031] like Figure 1-6 As shown, a lifting frame 107 is fixedly provided at the lower end of the electric lifting frame 104, and a protective cable 105 is fixedly connected between the lifting frame 107 and the inside of the electric lifting frame 104, and the protective cable 105 is connected to the input cable 106. A charging cable 103 is fixedly provided at the lower end of the lifting frame 107, and the charging cable 103 is connected to the protective cable 105. A charging gun 109 is fixedly provided at the other end of the charging cable 103, and the charging gun 109 is clamped and set inside the lifting frame 107. A plurality of telescopic rods 121 are fixedly provided at the bottom of the lifting frame 107 near the surrounding position of the charging cable 103, and a support pad 108 is fixedly provided on the opposite side of the plurality of telescopic rods 121, and movable blocks 123 are slidably provided inside the plurality of telescopic rods 121, and internal support springs 122 are fixedly connected between the plurality of movable blocks 123 and the inside of the telescopic rods 121, and pressure sensors 124 are fixedly provided at the ends away from each other inside the plurality of telescopic rods 121;

[0032] Specifically, in the above-mentioned specific embodiment, the electric lifting frame 104 drives the lifting frame 107 to perform lifting and lowering movements, and the protective cable 105 plays a connecting and protective role, ensuring that electric energy is safely transmitted from the input cable 106 to the charging cable 103. The charging cable 103 provides a power transmission channel for the charging gun 109. When the user takes the charging gun 109 and pulls it, the charging cable 103 is offset in the lifting frame 107, squeezing the support pad 108. After the support pad 108 is subjected to force, it pushes the movable block 123 in the telescopic rod 121 to compress the internal support spring 122. The movable block 123 moves to trigger the pressure sensor 124, and the pressure sensor 124 converts the pressure signal into an electrical signal and transmits it to the control system. The provision of the protective cable 105 protects the internal power transmission line and enhances the safety and stability of the system. The sensing system composed of components such as the pressure sensor 124, the telescopic rod 121, and the support pad 108 can sense the direction and degree of force on the charging cable 103 in real time, and provide accurate control signals for the subsequent automatic follow-up movement of the charging mechanism 1, thereby avoiding damage to the charging cable 103 due to excessive pulling, extending the service life of the cable, and reducing the difficulty of the user pulling the cable, thereby improving the convenience of the charging operation.

[0033] Specifically, the present invention uses the Arduino development board as the control module and combines the C / C++ language to write the code to implement this function. The specific implementation is as follows:

[0034] Hardware Connection:

[0035] The four pressure sensors are connected to analog pins A0-A3 of Arduino respectively.

[0036] The servo motor is connected to digital pin 9.

[0037] The relay that controls the oil pump is connected to digital pin 10.

[0038] Code implementation:

[0039]

[0040]

[0041]

[0042]

[0043] Code Description

[0044] Initialization part (setup function): Set up serial port communication for debugging output data, which makes it easy to view information such as pressure sensor values; initialize the input and output modes of the servo motor pins and oil pump control pins, and set the pressure sensor pins to input mode.

[0045] Read the pressure sensor value function (readPressureSensor): Use the analogRead function to read the analog value of the pressure sensor connected to the specified pin.

[0046] The main loop (loop function) continuously reads the values ​​of the four pressure sensors. When the value of a pressure sensor exceeds the set pressureThreshold, the servo motor is controlled to rotate to the corresponding angle (corresponding to different movement directions) according to different sensors (i.e. different directions). At the same time, the oil pump action is controlled (by controlling the relay connected to the oil pump circuit, etc.) to realize the movement of the charging mechanism. After moving for a period of time, the oil pump is stopped and the servo motor is reset. Finally, a short delay is added to avoid frequent operation.

[0047] like Figure 4-5 As shown, two first bearing seats 111 are fixedly provided on the upper end of the support base 102 near both sides, and a first rotating shaft 112 is fixedly provided between each of the four first bearing seats 111. Power rollers 110 are fixedly provided at both ends of the two first rotating shafts 112. Roller grooves 114 are provided inside the support base 102 near the positions of the four power rollers 110. The four power rollers 110 respectively pass through the four roller grooves 114 and are rolled on the inner upper ends of the two connecting seats 303. A second bevel gear 117 is fixedly provided on the two first rotating shafts 112 near one end. The upper end of the support base 102 is near the two second A second bearing seat 113 is fixedly provided at the position of the bevel gear 117, a second transmission shaft 115 is fixedly connected between the two second bearing seats 113, a first bevel gear 116 is fixedly provided at both ends of the second transmission shaft 115, the two first bevel gears 116 are respectively meshed with the two second bevel gears 117, and the meshing directions are opposite, a driven gear 120 is fixedly provided on the shaft body of the second transmission shaft 115, a servo motor 119 is fixedly provided at the upper end of the support base 102 near the position of the driven gear 120, a power gear 118 is fixedly provided at the output end of the servo motor 119, and the power gear 118 is meshed with the driven gear 120;

[0048] Specifically, in the above-described specific embodiment, after the servo motor 119 is activated, the power gear 118 at its output end rotates, and through meshing transmission with the driven gear 120, drives the second transmission shaft 115 to rotate. The first bevel gears 116 at both ends of the second transmission shaft 115 rotate accordingly. Due to the meshing relationship between the first bevel gear 116 and the second bevel gear 117, the second bevel gear 117 drives the first rotating shaft 112 to rotate. The power rollers 110 at both ends of the first rotating shaft 112 roll on the upper end of the connecting seat 303, thereby enabling the charging mechanism 1 to move on the longitudinal moving mechanism 3. The first bearing seat 111 and the second bearing seat 113 provide support and rotation bases for the first rotating shaft 112 and the second transmission shaft 115, respectively, ensuring the stable operation of the shaft system. This structural design that drives the power rollers 110 through gear transmission and shaft system rotation has high transmission efficiency and a stable transmission ratio, and can accurately control the movement speed and position of the charging mechanism 1. The servo motor 119 serves as a power source and can achieve precise speed and steering control to meet the movement requirements of the charging mechanism 1 in different scenarios, so that the charging mechanism 1 can move to the target position quickly and accurately, thereby improving the efficiency and accuracy of the charging operation.

[0049] like Figure 7 As shown, the two transverse movement mechanisms 2 each include two connecting frames 206, two stabilizing slide bars 205 are fixedly arranged between the two connecting frames 206, a sliding seat 204 is slidably arranged between the outsides of the two stabilizing slide bars 205, an oil tank is fixedly arranged inside one of the two connecting frames 206, an oil pump 201 is fixedly arranged on the upper end of the oil tank, a telescopic oil cylinder 202 is fixedly arranged on the output end of the oil pump 201, a connecting block 203 is fixedly arranged on the upper end of the sliding seat 204, and one end of the telescopic oil cylinder 202 is fixedly connected to the connecting block 203;

[0050] Specifically, in the above-mentioned specific embodiment, the oil pump 201 draws hydraulic oil from the oil tank, and drives the telescopic cylinder 202 to extend and retract by controlling the flow rate and pressure of the hydraulic oil. The extension and retraction of the telescopic cylinder 202 drives the connecting block 203 to move, and the connecting block 203 is connected to the sliding seat 204, so that the sliding seat 204 can slide smoothly on the stabilizing slide bar 205. The stabilizing slide bar 205 plays a guiding and supporting role, ensuring the linear motion accuracy of the sliding seat 204. The hydraulically driven lateral moving mechanism 2 has the advantages of large driving force, smooth movement, and a wide speed regulation range. It can easily drive the longitudinal moving mechanism 3 and the charging mechanism 1 to move in a large range in the lateral direction to meet the needs of vehicles with different parking distances and positions. At the same time, the stability and reliability of the hydraulic system are high, which can ensure the stable operation of the lateral movement function of the charging pile during long-term use.

[0051] like Figure 8As shown, the longitudinal movement mechanism 3 includes two stable slide rails 301, the lower ends of the two stable slide rails 301 are fixedly provided with lower reinforcement frames 302, and the connection seats 303 are fixedly provided near both sides between the two stable slide rails 301;

[0052] Specifically, in the above-mentioned specific embodiment, the stabilizing slide rail 301 provides a guide track for the movement of the charging mechanism 1 in the longitudinal direction, and its high-precision processing and installation ensure the straightness and smoothness of the movement of the charging mechanism 1. The lower reinforcement frame 302 enhances the structural strength and stability of the longitudinal moving mechanism 3, enabling it to withstand the weight of the charging mechanism 1 and various forces during the movement. The connecting seat 303 is used to install and fix related components, such as cooperating with the power roller 110 to achieve rolling connection, etc. The setting of the stabilizing slide rail 301 makes the charging mechanism 1 more precise and smooth during longitudinal movement, reducing shaking and deviation during movement. The lower reinforcement frame 302 improves the overall rigidity and anti-deformation ability of the longitudinal moving mechanism 3, extends the service life of the longitudinal moving mechanism 3, and ensures the long-term stable operation of the charging pile. The connecting seat 303 provides a reliable foundation for the installation and connection of components of the entire longitudinal moving mechanism 3, ensuring the coordinated work between the various components.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
