Description

Technical Field

[0001] The invention relates to the technical field of smart charging piles on highways, and in particular to a distributed smart self-service charging station and a method for using the same. Background Art

[0002] During the design, construction, and operation of expressways, service areas are typically set up at regular intervals (e.g., 60 kilometers). These service areas include basic facilities such as restaurants, gas stations, and charging stations to ensure the convenience of drivers and passengers. Currently, charging stations are concentrated in service areas. Due to site limitations, the number of charging stations cannot meet the demand for new energy vehicles. Field research and analysis reveals the following reasons:

[0003] 1. Long charging times for single vehicles. For example, taking a currently advanced electric vehicle and a supercharger as an example: if the battery is less than 20% charged, it takes about an hour to charge to 90%, allowing for a range of over 400 kilometers. Using a non-supercharger, a full charge can take around ten hours. Therefore, the longer charging times for electric vehicles compared to gasoline vehicles are a major factor. However, without breakthroughs in current battery technology, this long charging time will persist for a long time.

[0004] 2. Service area footprint: According to highway construction design standards, service areas have strict requirements for their floor space. Currently, a Class A service area covers a total area of ​​50 to 80 mu (approximately 1.5 to 2.5 acres). This requires design requirements for parking and rest areas, buildings, landscaping, and gas stations. Therefore, the area reserved for charging stations is limited. Generally speaking, the number of charging pile parking spaces within a service area will not exceed 20, with most having fewer than 10. While the shortage of charging piles could theoretically be solved by infinitely expanding the service area, this is not feasible in the short term.

[0005] Based on the above embarrassing situation, this technology provides a distributed intelligent self-service charging station on highways. Summary of the Invention

[0006] In order to address the deficiencies of the prior art, the present invention provides a distributed intelligent self-service charging station on a highway and a method of using the same, which is used to solve the problem in the prior art that centralized charging piles in highway service areas cannot meet the charging needs of vehicles.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] The distributed intelligent self-service charging station on the highway is a circular or approximately circular or trapezoidal charging platform extending toward the slope direction formed by local excavation and platform construction on the edge of the original highway, and a circular contour trough is set at the charging platform. The trough is a reinforced concrete structure. It is characterized in that: the self-service charging station includes a mechanical module, an intelligent charging pile and a control cabinet, wherein the mechanical module includes an axle seat, a rotating shaft assembly, a supporting wheel assembly, a drive motor and a rotating platform, and there is a central position of the trough. A boss structure, which is fixedly installed on the shaft seat by secondary pouring of concrete, and a rotating shaft assembly is installed on the shaft seat; the rotating shaft assembly is composed of a main shaft, a large sprocket, and a shaft sleeve, wherein the lower section of the main shaft is inserted into the shaft hole of the shaft seat, the middle section of the main shaft is a pillow block and cooperates with the upper end surface of the shaft seat, the upper section of the main shaft is a sprocket shaft section, and a flat key is used to connect the large sprocket and the sprocket shaft section; the shaft sleeve is sleeved on the upper end of the sprocket shaft section and fixedly connected, and the shaft sleeve is sleeved on the central through-hole of the rotating platform and welded;

[0009] Eight sets of supporting roller assemblies are installed in the ground trough below the rotating platform to support the rotating platform. A driving motor is installed on the rotating platform, wherein the motor shaft of the driving motor is arranged downward, and a small sprocket is installed on the motor shaft, and the small sprocket is connected to the above-mentioned large sprocket through a chain drive;

[0010] Two guardrails are installed on the upper surface of the rotating platform, dividing the space on the rotating platform into three parts: left, middle and right. The left and right sides are car parking areas with parking space lines drawn, and the middle area is where the smart charging pile, control cabinet and drive motor are placed;

[0011] Multiple photoelectric sensors are set at the position where the parking space line is drawn. The photoelectric sensors detect whether the parking space has been completely entered. If one of the photoelectric sensors detects that the line is pressed, the drive motor will not start;

[0012] Two limit switches are installed on the rotating platform, one at the edge of the left and the other at the edge of the parking area. A limit pin or a strong magnetic block used in conjunction with the limit switch is installed in the ground trough away from the emergency lane. The upper surface of the rotating platform is flush with the road surface, and a labyrinth sealing structure is set at the edge where the rotating platform and the ground trough meet, and a drainage channel is set at the lowest point of the ground trough.

[0013] Furthermore, a protective shed and a safety guardrail are added to the outer half as needed. The guardrail is preferably a double-wave guardrail to protect vehicles waiting to be charged. This protective shed has positive significance for high-latitude areas or on rainy days.

[0014] Furthermore, the two parking areas are numbered as parking space number one and parking space number two, wherein only one parking space is a working parking space and one parking space is a spare parking space. For easy identification, the guardrails can be painted in eye-catching colors such as red and yellow.

[0015] Furthermore, the driving motor is directly fixed on the motor base, and the motor base is movably mounted at the motor mounting hole of the rotating platform. The motor mounting hole is an elongated hole, and the length direction of the elongated hole is arranged along the radial direction of the rotating platform. The motor base and the rotating platform are mechanically connected by sliding fit, and a pull bolt assembly is arranged between the two for tightening, and the pull bolt assembly tightens the chain drive.

[0016] Furthermore, the supporting wheel assembly is composed of a supporting wheel, a bearing seat and an embedded part, wherein the embedded part is a steel plate welded part and is fixedly installed in the ground trough by secondary casting. Eight embedded parts are arranged along the circumference of the rotating platform and close to the edge. Two bearing seats are fixedly installed at each embedded part, and a supporting wheel is installed through the two bearing seats through the bearings. The supporting wheel is a conical wheel, which has an upward inclination angle toward the main axis direction, and the top of each supporting wheel cooperates with the annular rail at the bottom of the rotating platform. The annular rail is welded or bolted and directly fixed to the lower surface of the rotating platform. The annular rail is concentrically arranged relative to the rotation center, which can effectively solve the problem when there is local load on one side of the rotating platform.

[0017] Furthermore, a cable channel is reserved at the rotation center of the rotating platform and the main shaft for laying cables. This structure can meet the requirements of cable laying.

[0018] Furthermore, if a cable channel is set up, a cable drag chain can also be used between the rotating platform and the roadbed to protect the cables, meeting the need for free dragging of the rotating platform within a 180° range.

[0019] Furthermore, the rotating platform is composed of three layers of steel plates and ribs supported between the three layers of steel plates, forming a hollow structure, ensuring that it has sufficient rigidity to withstand the load of the vehicle without deformation.

[0020] Furthermore, bolts are provided between the sprocket and the pillow block to provide a safety redundancy design and improve the connection reliability between the Dalian wheel and the main shaft.

[0021] Furthermore, a polytetrafluoroethylene gasket or a stainless steel gasket is placed at the bottom of the shaft hole of the shaft seat, and lubricating grease or graphite powder is appropriately pre-placed to protect the end of the rotating shaft.

[0022] A method for using a self-service charging station utilizes the existing highway network. Along the highway, a self-service charging station is set up every N kilometers along the highway. The charging station is marked on the car navigation map. The driver selects the charging station to enter and drives the vehicle into the parking space of the charging station. Since the parking space is located in the emergency lane, the driver pays attention during the parking process. After the vehicle enters the charging station area, a gate-type emergency lane warning sign M meters behind is automatically erected. When the intelligent control module detects that the vehicle is not parked within the parking space line through the pressure sensor and the photoelectric sensor, the intelligent control module issues a voice warning. The driver should continue to adjust the vehicle posture until the vehicle is correctly parked in the parking space. Then, the intelligent control module controls the drive motor through the chain drive Drive the rotating platform to rotate 180 degrees counterclockwise and move the vehicle to the outer safe area. Then, the emergency lane warning sign is automatically raised and evacuated, and the emergency lane is reopened to traffic. The intelligent control module issues a voice prompt, reminding the driver that he can get off the vehicle to charge. The driver gets off the vehicle and connects the charging gun with the vehicle charging port. The driver can return to the car to rest. After charging is completed, the charging gun is unplugged and the driver returns to the car. The emergency lane warning sign warns the emergency lane, and the intelligent control module controls the rotating platform to rotate 180 degrees clockwise. The vehicle returns to the original route. After stopping steadily, the intelligent control module issues a voice prompt, indicating that the prompt is completed and can depart. The driver drives the vehicle away from the charging station and the emergency lane warning sign is evacuated, completing a charging cycle.

[0023] Furthermore, the intelligent control module includes a variety of sensors and a PLC controller. The sensors are used to sense whether the vehicle is parked in a parking space and to sense the rotation angle of the rotating platform.

[0024] The beneficial effects of the present invention are:

[0025] Distributed intelligent self-service charging stations on highways. The distribution means that the centralized charging columns are evenly distributed along the highway. For example, an intelligent self-service charging station is set up every 5 kilometers. Vehicles traveling on the highway can choose to stop at the nearest intelligent self-service charging station for charging as needed, and warning facilities are configured as needed to ensure the safety of parking and charging. The distributed charging stations are mobile and flexible.

[0026] The establishment of this self-service charging station does not occupy the site of the service area. It is only necessary to carry out electrification transformation of the part along the highway. The transformation process only requires semi-closed construction of the local emergency lane, which does not affect normal traffic and has low transformation costs.

[0027] The electrical equipment of the self-service charging station in this technology can be installed by factory assembly and on-site assembly and installation, which has high construction efficiency.

[0028] During the charging process of this technology, vehicles and personnel are moved to the outside of the guardrail to ensure safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Distributed intelligent self-service charging stations on highways replace the existing centralized setup with a distributed layout. Charging stations are located at regularly spaced locations along the highway curbs, for example, every 3-5 kilometers. Construction requires only partial excavation of the curb. During this excavation, the highway can be partially closed off, ensuring no traffic interruption. To speed construction, the charging stations are integrated using prefabricated modules. Individual modules are preassembled into several separate modules in the factory. On-site construction requires only the formation of the trench and foundation, followed by prefabricated installation. The structure and principles of this integrated prefabricated module are described in detail below. Specific embodiment 1

[0055] refer to Figures 1 to 10 The series of figures shown reproduce the implementation process of this embodiment.

[0056] The self-service charging station includes a mechanical module 100, a charging pile module 200, and an intelligent control module 300. The mechanical module 100 is used to transfer the vehicle from the emergency lane to the outside of the guardrail to put it in a safe state, and has a 180-degree rotation action.

[0057] The charging pile module 200 is used to charge new energy vehicles. It can be matched with any smart charging pile currently on the market and installed on a rotating platform for charging.

[0058] The intelligent control module 300 includes a variety of sensors and PLC controllers. The sensors are used to sense whether the vehicle is parked in the parking space, and automatically set up an electric warning sign behind the emergency lane after parking to prevent subsequent vehicles from entering by mistake, as well as sense the rotation angle of the rotating platform. Specifically, the intelligent control module controls the mechanical module to rotate 180 degrees counterclockwise, moving the vehicle from the emergency lane to the outside of the curb, so that it is in a safe state. The charging gun in the intelligent charging module is then docked with the charging port of the new energy vehicle for charging. After charging is completed, the charging gun is removed and returned to its original position. Then, the intelligent control module controls the mechanical module to rotate 180 degrees clockwise, moving the vehicle to the emergency lane. The vehicle starts and leaves, completing a charging cycle.

[0059] Mechanical module 100 is installed in a trough using a trough-type installation method. Before installing the mechanical module, civil engineering construction is required. Specifically, a charging platform 400 is formed by partial excavation and platform construction along the existing roadside, extending toward the slope. This charging platform provides space for mechanical equipment and charging facilities. The trough 410 has a circular profile and, based on the installation requirements of the mechanical module, has multiple steps for installing the mechanical module. The trough is preferably cast from reinforced concrete to provide sufficient installation strength.

[0060] The mechanical module 100 includes an axle seat 110, a rotating shaft assembly 120, a supporting wheel assembly 130, a driving motor 140 and a rotating platform 150. Among them, there is a slightly protruding boss structure 411 at the central position of the ground trough 410. The boss structure is a reinforced concrete structure, and an axle seat 110 is fixedly installed on the boss structure by pouring concrete twice. The axle seat 110 is a three-dimensional structure composed of a base plate 111, a rib plate 112, a cylinder 113 and a support plate 114. The axle seat 110 has a vertically arranged shaft hole for installing a rotating shaft. Specifically, the base plate is circular and arranged horizontally. The cylinder 113 is welded to the upper side of the base plate, and a circular support plate 114 is welded and fixed to the upper edge of the cylinder. The support plate is circular and welded to the cylinder. There are multiple ribs arranged vertically. The middle and lower parts of the ribs are welded to the support plate, cylinder and bottom plate respectively, and the three are formed into a whole by welding. The space between the ribs is filled with concrete. After welding, a firm axle seat is formed and firmly fixed in the concrete.

[0061] Furthermore, a polytetrafluoroethylene gasket or a stainless steel gasket 115 is placed at the bottom of the shaft hole of the shaft seat 110, and lubricating grease or graphite powder is appropriately pre-placed to protect the end of the rotating shaft.

[0062] The rotating shaft assembly 120 is mainly composed of a main shaft 121, a large sprocket 122, and a shaft sleeve 123, wherein the lower section of the main shaft 121 is a thick section, which is inserted into the above-mentioned shaft hole, the middle section of the main shaft is a pillow block, which falls on the above-mentioned support plate to form an end face fit, and the upper section of the main shaft is a sprocket shaft section, that is, the large sprocket is put on the sprocket shaft section from top to bottom, and a flat key connection 124 is used between the sprocket and the sprocket shaft section.

[0063] Furthermore, bolts are provided between the sprocket and the pillow block to provide a safety redundancy design and improve the connection reliability between the Dalian wheel and the main shaft.

[0064] The shaft sleeve 123 is sleeved on the upper end of the sprocket shaft segment, and the two are fastened together using fastening bolts. At the same time, the shaft sleeve 123 is sleeved on the central through-hole of the rotating platform 150, and the two are welded together. In other words, after welding, the outer side of the shaft sleeve is welded to the rotating platform.

[0065] Therefore, the rotating platform has the ability to rotate relative to the main shaft.

[0066] Furthermore, a cable channel 600 is reserved at the rotation center of the rotating platform and the main shaft for laying cables. This structure can meet the requirements of cable laying.

[0067] Furthermore, if a cable channel is set up, a cable drag chain can also be used between the rotating platform and the roadbed to protect the cables, meeting the need for free dragging of the rotating platform within a 180° range.

[0068] The rotating platform 150 is composed of three layers of steel plates and ribs supported between the three layers of steel plates, forming a hollow structure to ensure that it has sufficient rigidity to withstand the load of the vehicle without deformation.

[0069] Eight sets of supporting roller assemblies 130 are installed in the ground trough below the rotating platform 150. The eight supporting roller assemblies support the rotating platform. Specifically, each supporting roller assembly is composed of a supporting roller 131, a bearing seat 132 and an embedded part 133. The embedded part 133 is a steel plate welded part and is fixedly installed in the ground trough 410 by secondary casting. The eight embedded parts are arranged along the circumference of the rotating platform and close to the edge. The layout method is referenced. Figure 1. Two bearing seats are fixedly installed at each embedded part by bolts, and a supporting wheel 131 is installed through the two bearing seats through the bearings. The supporting wheel 131 is a conical wheel, which has a slightly upward tilt angle toward the main axis, and the top of each supporting wheel cooperates with the annular rail 151 at the bottom of the rotating platform. The annular rail 151 is directly fixed to the lower surface of the rotating platform by welding or bolts. The annular rail is concentrically arranged relative to the center of rotation, which can effectively solve the problem of no overloading when there is a local load on one side of the rotating platform. In this embodiment, the eight supporting wheels are arranged obliquely upward and have an angle of about 10 degrees with the horizontal plane. According to the force decomposition analysis, the eight supporting wheels have an outward-acting centering force on the upper annular rail, so that a reasonable lifting force and centripetal force are maintained between the supporting wheel and the annular rail.

[0070] The driving motor 140 is installed on the above-mentioned rotating platform. For specific installation methods, refer to Figure 3 , Figure 3 In the embodiment, the motor shaft of the driving motor is set downward, and a small sprocket 141 is installed on the motor shaft. The small sprocket 141 and the above-mentioned large sprocket 122 are connected by a chain transmission 142. The tensioning structure of the chain is as follows: the above-mentioned driving motor 140 is directly fixed on the motor base 143, and the motor base is movably placed on the motor mounting hole 152 of the rotating platform 150. The motor mounting hole is a long hole, and the length direction of the long hole is set along the radial direction of the rotating platform. The motor base 143 and the rotating platform 150 are mechanically connected by sliding fit, and a tension bolt assembly 144 is set between the two for tensioning. The chain transmission is tightened by the tension of the tension bolt assembly. The driving motor drives the rotating platform to rotate along the main axis, and cooperates with the support of eight sets of roller assemblies to ensure smooth operation under vehicle load and prevent jamming.

[0071] Two guardrails 153 are provided on the upper surface of the rotating platform 150. The two guardrails are arranged parallel to each other. Preferably, the guardrails are upright columns and double-wave guardrail structures, which are the same as the guardrail structures on both sides of the highway. The space on the rotating platform is divided into three parts: left, middle and right. The left and right sides are car parking areas, and lines are drawn in the areas, which are car parking spaces. For easy identification, the guardrails 153 can be painted in eye-catching colors such as red and yellow for easy identification. The area between the two guardrails is the equipment placement area, in which electrical equipment such as smart charging piles 210 and control cabinets 310 are placed. And optimally, the installation position of the above-mentioned drive motor also falls within this area. By installing the equipment, this area forms an equipment area.

[0072] Furthermore, the two parking areas are numbered as parking space No. 1 and parking space No. 2, wherein only one parking space is a working parking space and one parking space is a spare parking space.

[0073] Each parking space is marked with a prominent reflective paint line. Multiple photoelectric sensors 320 are located at the markings to detect whether a vehicle has fully entered the space. If any of the sensors detects a vehicle crossing the line, the drive motor will not start. This configuration prevents vehicles from partially entering the parking space.

[0074] The rotating platform is equipped with two limit switches 330, one in each of the left and right zones. Specifically, they are installed on the outermost sides of the two zones. A stop pin or strong magnet, used in conjunction with the limit switches, is installed in the floor trough, away from the emergency lane. If the limit switch is a mechanical switch, the rotating platform automatically stops when it contacts the stop pin. If the limit switch is a magnetic switch, the rotating platform automatically stops when it senses the strong magnet.

[0075] After installation, the upper surface of the rotating platform is flush with the road surface of the highway emergency lane, and the edge of the rotating platform and the groove are treated with waterproof and dustproof treatment. Figure 4 Specifically, a U-shaped groove is provided at the edge of the groove, and an N-shaped channel steel is welded to the edge of the rotating platform. The two are interlocked to form a labyrinth seal structure 154. Water accumulated in the U-shaped groove is drained out through a drainage hose, preventing a large amount of rainwater from entering the trough. A drainage channel is also provided at the lowest point of the trough to drain a small amount of rainwater that enters the trough into a roadside ditch. This design can effectively prevent water from accumulating in the trough.

[0076] Furthermore, a protective shed 500 and a safety guardrail are added to the outer half as needed. The guardrail is preferably a double-wave guardrail to protect vehicles waiting to be charged. This protective shed has positive significance for high-latitude areas or on rainy days.

[0077] A method for using a self-service charging station. This technology utilizes the existing highway network. Along the highway, the self-service charging station is set up every N kilometers along the highway, and protective sheds are installed according to the latitude.

[0078] Charging stations are marked on the car's navigation map. The driver selects the charging station they want to enter and drives into the parking space at the charging station. Since the parking space is located within the emergency lane, the driver must observe carefully while parking. Once the vehicle enters the charging station area, a gate-type emergency lane warning sign 700 automatically erects 150 meters behind the vehicle. This so-called gate-type emergency lane warning sign is a modified version of an existing gate at an existing highway toll station. The sign is fixed to the gate's crossbar to create a warning effect and block the emergency lane, preventing oncoming vehicles from entering the area. When the intelligent control module 300 detects that the vehicle is not parked within the marked parking space through pressure sensors and photoelectric sensors, it issues a voice warning, prompting the driver to continue adjusting the vehicle's posture until the vehicle is properly parked. The intelligent control module 300 then controls the drive motor to rotate the rotating platform 180 degrees counterclockwise via a chain drive, moving the vehicle to a safe outer area. The emergency lane warning sign then automatically raises and moves away, and the intelligent control module 300 issues a voice prompt, telling the driver to exit the vehicle to charge. The driver then disengages the charging cord and connects the charging port to the vehicle, returning to the vehicle to rest. Once charging is complete, the driver unplugs the charging cord, returns to the vehicle, and selects the "End" button on the mobile app. The emergency lane warning sign then signals the emergency lane, and the intelligent control module 300 controls the rotating platform to rotate 180 degrees clockwise, returning the vehicle along its original route. Once the vehicle comes to a complete stop, the intelligent control module 300 issues a voice prompt, announcing the completion and the vehicle's departure. The driver then leaves the charging station, and the emergency lane warning sign moves away, completing a charging cycle.

[0079] The cables in this technology are laid nearby and can be powered by municipal or urban and rural national power grids, which has the advantage of saving investment. Specific embodiment 2

[0081] refer to Figure 11 This embodiment differs from the first embodiment in that the charging station is positioned further outboard than in the first embodiment, specifically, completely outside the guardrail. This design advantage is that it does not occupy the emergency lane, making it particularly convenient for parking vehicles waiting to be charged. Specifically, a circular or approximately circular, or trapezoidal or approximately trapezoidal charging station is formed by partially excavating and constructing the platform along the existing highway, extending toward the slope.

[0082] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention.

6. A method for using a self-service charging station. Utilizing the existing highway network, self-service charging stations are set up every N kilometers along the highway. The charging stations are marked on the car navigation map. The driver selects the charging station to enter and drives the vehicle into the parking space at the charging station. Since the parking space is located in the emergency lane, the driver should pay attention during the parking process. After the vehicle enters the charging station area, a gate-type emergency lane warning sign is automatically erected M meters behind the vehicle. When the intelligent control module detects that the vehicle is not parked within the parking space line through the pressure sensor and the photoelectric sensor, the intelligent control module issues a voice warning. The driver should continue to adjust the vehicle posture until the vehicle is correctly parked in the parking space. Then, the intelligent control module controls the drive motor to drive the rotating The rotating platform rotates 180 degrees counterclockwise to move the vehicle to the outer safe area. Then, the gate-type emergency lane warning sign automatically raises and evacuates, and the emergency lane resumes traffic. The intelligent control module issues a voice prompt to remind the driver to get off the vehicle for charging. The driver gets off the vehicle and connects the charging gun with the vehicle's charging port. The driver can return to the car to rest. After charging is completed, the charging gun is unplugged and the driver returns to the car. The gate-type emergency lane warning sign warns the emergency lane. The intelligent control module controls the rotating platform to rotate 180 degrees clockwise and the vehicle returns to the original route. After stopping steadily, the intelligent control module issues a voice prompt to indicate that the prompt is complete and can depart. The driver drives the vehicle out of the charging station and the gate-type emergency lane warning sign is evacuated, completing a charging cycle.

7. The method for using a self-service charging station according to claim 6, characterized in that: The intelligent control module includes a variety of sensors and a PLC controller.
