Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile for highway service areas. Background Technology

[0002] With the continuous growth in the number of new energy vehicles, highway service area charging infrastructure is facing unprecedented operational pressure. Currently, the widely used fixed charging piles are generally located in ordinary parking areas, lacking effective management and physical isolation measures for dedicated charging spaces. This leads to a serious problem of gasoline-powered vehicles illegally occupying charging spaces. Statistics show that during peak hours, gasoline-powered vehicles occupy as many as 40%-60% of charging spaces, severely impacting the normal charging experience for electric vehicle users.

[0003] Furthermore, existing charging stations are mostly centralized and fixed installations, making it difficult to dynamically adjust their layout according to traffic flow. When faced with tidal traffic flow, this can easily cause localized congestion and traffic path conflicts, leading to a decrease in overall charging efficiency. At the same time, due to the lack of intelligent management methods, current supervision mainly relies on manual inspections and static signage, making it difficult to achieve 24 / 7 monitoring and traceability of violations, resulting in low management efficiency. Summary of the Invention

[0004] To overcome the problems mentioned in the background art, the present invention provides a charging pile for highway service areas.

[0005] The technical solution is as follows: A charging pile for a highway service area includes a cabinet, in which a charging control module is detachably installed. A first cable is provided on the cabinet and is plugged into the charging control module. The first cable is connected to a charging gun. Four equally spaced legs are provided at the bottom of the cabinet, and electric wheels are provided at the bottom of the legs. A guide frame is fixedly connected to the cabinet, and a first fixed frame is fixedly connected to the guide frame. A sliding frame is slidably provided on the guide frame. Both the first fixed frame and the sliding frame are rotatably provided with wheels for guiding the first cable.

[0006] More preferably, the weight of the sliding frame is greater than the weight of the charging gun.

[0007] More preferably, both the first fixed frame and the sliding frame are rotatably equipped with rotating rollers, which are used to squeeze the first cable.

[0008] More preferably, the charging gun is fixedly connected to symmetrically distributed first electric push rods, and each of the symmetrically distributed first electric push rods is electrically connected to the charging control module.

[0009] More preferably, the guide frame is slidably provided with a limit strip, and multiple springs are installed between the limit strip and the guide frame. The sliding frame is equipped with a limit wheel via an electric rotating shaft, and the limit strip is used to compress the limit wheel.

[0010] More preferably, it also includes: a fixed base, which is set on the ground and has a socket inside; a second cable, which is set on the cabinet and has plugs at both ends, one plug of the second cable being electrically connected to the charging control module and the other plug of the second cable being electrically connected to the socket on the fixed base.

[0011] More preferably, it further includes: a second electric push rod, fixedly connected to the cabinet; a sliding shell, slidably disposed on the cabinet, the telescopic end of the second electric push rod being fixedly connected to the sliding shell; a second fixing frame, fixedly connected to the sliding shell, and the second cable being fixedly connected to the second fixing frame.

[0012] More preferably, the fixed base is provided with two swing plates for limiting rotation, and a torsion spring is installed between the swing plates and the fixed base. When the two swing plates contact the fixed base, they are used to wrap the socket on the fixed base. The second fixed frame is fixedly connected to two fixed plates, which are used to press the adjacent swing plates.

[0013] More preferably, it also includes: four limiting posts, all fixed to the fixed base; four elastic telescopic rods, all fixed to the second fixed frame; and two fixing blocks, respectively fixed to the adjacent elastic telescopic rods. The fixing blocks are provided with two blind holes. When the limiting post is inserted into the corresponding blind hole on the adjacent fixing block, the socket on the fixed base is aligned with the corresponding plug on the second cable.

[0014] More preferably, two symmetrically distributed limiting plates are fixed to the lower surface of the fixing block, and the limiting plates are used to guide the movement of the adjacent limiting posts.

[0015] The beneficial effects of this invention are as follows: By operating the electric wheels on the outriggers, the cabinet is moved to the side of the vehicle requiring charging, facilitating timely charging of electric vehicles. Simultaneously, the cabinet moves to an empty area, alleviating the pressure of vehicle queues and preventing overcrowding in the service area. Guided by the first fixed frame and sliding frame, the first cable is wound up, keeping it suspended in the air when not charging, preventing it from being run over by vehicles. The operation of the first electric push rod automatically ejects the charging gun, facilitating charging of other electric vehicles. The limiting strip limits the positioning of the limiting wheels, ensuring the sliding frame... In the limiting state, the first cable is kept extended to a specified length to prevent it from contacting the ground during charging. By setting a fixed base, the socket on the fixed base is connected to the adjacent plug on the second cable, connecting the charging pile to the power grid. This increases the charging modes of the charging pile, making it easier for operators to select the appropriate charging mode. At the same time, multiple fixed bases are set in different locations in the service area to ensure the continuity of power supply to the charging pile. By inserting the limiting post into the corresponding blind hole on the adjacent fixed block, the plug on the second cable can be automatically inserted into the socket on the fixed base, simplifying the operation process, reducing the difficulty of use, and improving the convenience of use.

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0024] Example 1: A charging pile in a highway service area, referring to... Figures 1-3 As shown, the system includes a cabinet 1, inside which a charging control module 2 is detachably installed. The detachable design of the charging control module 2 facilitates quick maintenance of the charging station and ensures its normal operation in the service area. A battery is installed inside the cabinet 1, and a display terminal is located on the upper front side of the cabinet 1. Both the battery and the display terminal are electrically connected to the charging control module 2. A first cable 3 is installed on the cabinet 1, which is plugged into the charging control module 2 and connected to a charging gun 4. Four equally spaced support legs 5 are located at the bottom of the cabinet 1, and electric wheels are installed at the bottom of each support leg 5. The electric wheels on the support leg 5 operate, allowing the cabinet 1 to move freely, facilitating charging of the corresponding vehicle after the cabinet 1 is moved to the designated position. A guide frame 6 is fixedly connected to the left side of the cabinet 1, and a first fixed frame 7 is fixedly connected to the upper part of the guide frame 6. A sliding frame 9 is slidably mounted on the guide frame 6. Both the first fixed frame 7 and the sliding frame 9 are rotatably mounted with wheels. The weight of the sliding frame 9 is greater than the weight of the charging gun 4. The first cable 3 first passes around the wheel on the sliding frame 9, and then passes around the wheel on the first fixed frame 7. Both the first fixed frame 7 and the sliding frame 9 are rotatably mounted with rotating rollers 10, which are used for extrusion. The first cable 3 is pressed down to prevent it from derailing from the wheel on the first fixed frame 7 (or the wheel on the sliding frame 9); the charging gun 4 is fixedly connected to two symmetrically distributed first electric push rods 11, both of which are electrically connected to the charging control module 2. When the charging control module 2 detects that the vehicle is fully charged, it starts timing. When the recorded time reaches a specified value, the charging control module 2 controls the two first electric push rods 11 to work, and the telescopic ends of the first electric push rods 11 extend, causing the charging gun 4 to detach from the vehicle; the guide frame 6 is slidably equipped with The limiting strip 12 has evenly distributed triangular notches. Multiple springs are installed between the limiting strip 12 and the guide frame 6. The sliding frame 9 is equipped with a limiting wheel 13 via an electric rotating shaft. The electric rotating shaft is electrically connected to the charging control module 2. When the electric rotating shaft stops working (the electric rotating shaft is in a self-locking state), the limiting wheel 13 is stationary relative to the sliding frame 9. The limiting wheel 13 has circumferentially evenly distributed triangular protrusions. The triangular protrusions of the limiting wheel 13 are located in the corresponding triangular notches on the limiting strip 12, so that the sliding frame 9 and the guide frame 6 are in a relatively stationary state.

[0025] The working process of the charging pile in this embodiment is as follows:

[0026] When an electric vehicle parks in a designated parking space at a highway service area, the service area's video surveillance system detects the vehicle's location. Based on this location, the system moves the charging station. The electric wheels on the support leg 5 engage, moving the control cabinet 1 next to the electric vehicle. The operator then pulls the charging gun 4, which moves the first cable 3. This movement of the first cable 3 compresses the rotating wheel on the sliding frame 9, causing the sliding frame 9 to move upwards along the guide frame 6. The sliding frame 9 then moves the limit wheel 13 upwards via an electric shaft. Because the electric shaft is in a self-locking state, the electric shaft and the limit wheel 13 cannot rotate, thus limiting the movement. The wheel 13 moves upward and presses against the limiting strip 12. The limiting strip 12 moves and compresses the connected spring. The limiting wheel 13 moves upward along the limiting strip 12. After the charging gun 4 is located at the charging port of the electric vehicle, the pulling on the charging gun 4 stops. At this time, under the elastic force of the spring connected to the limiting strip 12, the triangular protrusion on the limiting wheel 13 is re-inserted into the corresponding triangular notch on the limiting strip 12. Under the limiting cooperation of the triangular protrusion on the limiting wheel 13 and the triangular notch on the limiting strip 12, the sliding frame 9 is in a relatively static state with the guide frame 6 again, so that the first cable 3 maintains its extended length and avoids the first cable 3 being on the ground during the charging process.

[0027] After charging is completed, the operator unplugs the charging gun 4. (If the charging gun 4 is not unplugged in time, the charging control module 2 will start a timer after charging is completed. After the set time is reached, the charging control module 2 will control the first electric push rod 11 to work, so that the charging gun 4 will automatically disengage from the electric vehicle.) Then the charging control module 2 controls the electric rotating shaft to work. The electric rotating shaft drives the limit wheel 13 to rotate. The limit wheel 13 rotates and moves downward along the limit bar 12. The limit wheel 13 drives the sliding frame 9 to move downward through the electric rotating shaft. The sliding frame 9 moves downward so that the upper rotating wheel of the sliding frame 9 squeezes the first cable 3, so that the first cable 3 and the charging gun 4 return to their initial state. When the electric vehicles in other positions need to be charged, the control cabinet 1 can be moved to the corresponding position.

[0028] In the service area, some charging piles are moved next to the vehicles for charging, while others are in the charging area. When the battery of a charging pile in use is low, it is moved to the charging area to replenish its power and replace the charging pile in the charging area to charge other vehicles.

[0029] Example 2: Based on Example 1, referring to... Figure 1 , Figure 4 and Figure 5As shown, it also includes: a fixed base 14, which is set on the ground and has a socket inside, which is connected to the power grid; and a second cable 15, which is set on the cabinet 1. Both ends of the second cable 15 are provided with plugs. The plug at the upper end of the second cable 15 is electrically connected to the charging control module 2, and the plug at the lower end of the second cable 15 is used to electrically connect to the socket on the fixed base 14, so that the operator can select AC charging or DC charging on the charging pile. Multiple fixed bases 14 can be set up in a distributed manner in the service area to facilitate charging operations in different areas of the service area.

[0030] The working process of this embodiment follows that of Embodiment 1, and is described in detail as follows:

[0031] When a vehicle needs to be charged using a charging station, the electric wheels on the outrigger 5 are controlled to move the charging station closer to the fixed base 14. Then, the plug on the second cable 15 is connected to the socket on the fixed base 14, connecting the charging station to the power grid. In this state, the charging station can perform both DC and AC charging, increasing the charging modes. At the same time, the power grid replenishes the battery in the charging station in real time. The vehicle is then parked near the fixed base 14, and the charging operation can be repeated. This setup, combined with the movement of the charging station, facilitates charging operations for vehicles in different locations within the service area. Furthermore, this setup allows more charging stations to be moved to vacant areas during peak hours, reducing traffic congestion and waiting time, thus improving charging efficiency. This setup also significantly enhances the convenience and practicality of using the charging station.

[0032] Example 3: Based on Example 2, referring to... Figures 4-6 As shown, it also includes: two symmetrically distributed second electric push rods 16 (the quantity is as described in the attached figure), both second electric push rods 16 are electrically connected to the charging control module 2, and both second electric push rods 16 are fixed to the lower part of the cabinet 1; a sliding shell 17, which is slidably disposed in the lower part of the cabinet 1, and the telescopic ends of the second electric push rods 16 are fixed to the sliding shell 17; a second fixing frame 18, which is fixed to the upper part of the sliding shell 17, and the second cable 15 is fixed to the second fixing frame 18; two swing plates 19 are rotatably limited on the upper part of the fixing base 14, the swing plates 19 cover the upper surface of the fixing base 14, and a torsion spring is installed between the swing plates 19 and the fixing base 14. The torsion spring is always in a torsional state. In the initial state, the tops of the two swing plates 19 are in contact. At this time, the two swing plates 19 are sealed and fitted with the fixing base 14, and the three seal and wrap the socket on the fixing base 14. The second fixing frame 18 is fixed to two fixing plates 20, and the fixing plates 20 are used to press the adjacent swing plates 19.

[0033] The working process of this embodiment follows that of embodiment 2, and is described in detail as follows:

[0034] In the initial state, the telescopic end of the second electric push rod 16 is in the retracted state. After the charging pile is moved to directly above the fixed base 14, the power connection operation is selected through the display terminal. The charging control module 2 causes the two second electric push rods 16 to work. The telescopic end of the second electric push rod 16 drives the sliding shell 17 to move downward. The sliding shell 17 drives the second fixed frame 18 and the two fixed plates 20 to move downward together. The fixed plate 20 moves downward to contact and press the adjacent swing plate 19, causing the swing plate 19 to swing and release the obstruction of the socket on the fixed base 14 (the swing plate 19 will eventually swing to a vertical state). Then the second fixed frame 18 continues to drive the second cable 15 to move downward, so that the plug of the second cable 15 is inserted into the socket of the corresponding fixed base 14. At this time, the sliding shell 17 contacts the ground, and the second electric push rod 16 stops working, completing the connection between the charging pile and the power grid. The power grid charges the battery in the charging pile. When a vehicle needs to be charged later, the above operation can be repeated.

[0035] Example 4: Based on Example 3, referring to... Figures 1-6 As shown, four equally spaced limiting posts 21 are fixed to the fixed base 14 (this number is the quantity shown in the attached figure, and the actual number can be adjusted according to the actual situation). The upper side of the limiting posts 21 is provided with an inclined surface. Four equally spaced elastic telescopic rods 22 are fixed to the second fixed frame 18. The lower ends of two adjacent elastic telescopic rods 22 are fixed to a fixed block 23. The fixed block 23 is provided with two blind holes. The diameter of the limiting post 21 is the same as the diameter of the blind hole on the fixed block 23. When the limiting post 21 is inserted into the corresponding blind hole on the adjacent fixed block 23, the socket on the fixed base 14 is aligned with the corresponding plug on the second cable 15. Two symmetrically distributed limiting plates 24 are fixed to the lower surface of the fixed block 23. The distance between two adjacent limiting plates 24 is divided into three segments, of which the two outer segments are set with varying diameters, and the middle segment is set with equal distances. The limiting plates 24 are used to guide the movement of adjacent limiting posts 21.

[0036] The working process of this embodiment follows that of embodiment 3, and is described in detail as follows:

[0037] As the cabinet 1 moves to directly above the corresponding fixed base 14, the electric wheels on the support legs 5 operate, first positioning the cabinet 1 behind the fixed base 14 (towards the attached...). Figure 4Taking the central direction as an example), the cabinet 1 is then controlled to move forward. The movement of the cabinet 1 drives the fixed block 23 and the limiting plate 24 to move through the connected parts. During the movement of the cabinet 1, the limiting plate 24 contacts the limiting post 21. Due to the guiding effect of the limiting plate 24, the cabinet 1 swings slightly until the cabinet 1 moves directly above the fixed seat 14 (observed by the existing video detection unit, existing parts, not shown in the attached figure). The operation of the electric wheel on the support leg 5 is stopped. Then, the telescopic end of the second electric push rod 16 is extended. The operation in embodiment 3 is repeated. However, during this process, the second fixed frame 18 simultaneously drives the fixed block 23 to move down through the elastic telescopic rod 22, so that the limiting post 21 is inserted into the corresponding blind hole on the adjacent fixed block 23, which improves the connection stability between the cabinet 1 and the fixed seat 14. This facilitates the automatic and accurate insertion of the plug of the second cable 15 connected to the second fixed frame 18 into the socket of the fixed seat 14. The subsequent charging operation repeats the operation in embodiment 1. If the charging pile needs to be moved, the above reverse operation can be performed.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
