Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile in a highway service area. Background Art

[0002] With the continuous growth of new energy vehicle ownership, the charging infrastructure in highway service areas is facing unprecedented operating pressure. Currently, the widely used fixed charging piles are generally set up in ordinary parking areas. There is a lack of effective management and physical isolation measures for dedicated charging parking spaces, resulting in a serious phenomenon of fuel vehicles illegally occupying charging parking spaces. According to statistics, during peak hours, the proportion of fuel vehicles occupying charging parking spaces is as high as 40%-60%, seriously affecting the normal charging experience of electric vehicle users.

[0003] In addition, most of the existing charging piles are centralized and fixed, which makes it difficult to dynamically adjust the layout according to traffic flow. When facing tidal vehicle flow, it is easy to cause local congestion and traffic path conflicts, resulting in a decrease in overall charging efficiency. At the same time, due to the lack of intelligent management methods, the current supervision mainly relies on manual inspections and static signs, which makes it difficult to achieve all-weather monitoring and violation tracing, and the management efficiency is low. Summary of the invention

[0015] The beneficial effects of the present invention are as follows: Through the operation of the electric wheels on the outriggers, the cabinet body is controlled to move beside the vehicle to be charged, facilitating the timely charging operation of electric vehicles. At the same time, the cabinet body moves to the idle area, dispersing the pressure of vehicle queuing and avoiding overcrowding in the service area.

[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0019] Example 1: A charging pile in a highway service area, referring to Figures 1 - 3 As shown, it includes a cabinet 1, in which a charging control module 2 is detachably installed. The detachable setting of the charging control module 2 facilitates the rapid maintenance of the charging pile, ensuring the normal operation of the charging pile in the service area. A battery is arranged in the cabinet 1, and a display terminal is arranged on the upper part of the front side of the cabinet 1. The battery and the display terminal are both electrically connected to the charging control module 2. A first cable 3 is arranged on the cabinet 1, and the first cable 3 is plugged with the charging control module 2. The first cable 3 is connected to a charging gun 4; four equally spaced legs 5 are arranged at the bottom of the cabinet 1, and an electric wheel is arranged at the bottom of the legs 5. , the electric wheels on the legs 5 work, so that the cabinet 1 can move freely, so that the cabinet 1 can be moved to the designated position to charge the corresponding vehicle. 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. The guide frame 6 is slidably provided with a sliding frame 9. The first fixed frame 7 and the sliding frame 9 are both rotatably provided with a rotating wheel. 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 rotating wheel on the sliding frame 9, and then passes around the rotating wheel on the first fixed frame 7; the first fixed frame 7 and the sliding frame 9 are both rotatably provided with a rotating roller 10, and the rotating roller 10 is used to squeeze The first cable 3 is pressed to prevent the first cable 3 from derailing on the rotating wheel of the first fixed frame 7 (or the rotating wheel on the sliding frame 9); the charging gun 4 is fixedly connected with two symmetrically distributed first electric push rods 11, and the two first electric push rods 11 are electrically connected to the charging control module 2. When the charging control module 2 detects that the vehicle is fully charged, the charging control module 2 starts to record time. 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 end of the first electric push rod 11 extends to make the charging gun 4 out of contact with the vehicle; the guide frame 6 is slidably provided with The limit strip 12 is provided with evenly distributed triangular notches, and a plurality of springs are installed between the limit strip 12 and the guide frame 6. The sliding frame 9 is provided with a limit wheel 13 through an electric shaft, and the electric shaft is electrically connected to the charging control module 2. When the electric shaft stops working (the electric shaft is in a self-locking state), the limit wheel 13 is in a stationary state relative to the sliding frame 9. The limit wheel 13 is provided with triangular protrusions equidistantly distributed in the circumferential direction, and the triangular protrusions of the limit wheel 13 are located in the corresponding triangular notches on the limit strip 12, so that the sliding frame 9 and the guide frame 6 are in a relatively stationary state.

[0020] The working process of the charging pile in this embodiment is as follows: After the electric vehicle is parked in the designated parking space of the highway service area, the video monitoring system of the service area will detect the parking position of the vehicle, and then, according to the parking position of the electric vehicle, dispatch the charging pile to move. Among them, the electric wheels on the outriggers 5 work, and the control cabinet 1 is moved to the side of the electric vehicle. Subsequently, the operator pulls the charging gun 4, and the charging gun 4 drives the first cable 3 to move. The movement of the first cable 3 will squeeze the runner on the sliding frame 9, causing the sliding frame 9 to move upward along the guiding frame 6. Then, the sliding frame 9 drives the limiting wheel 13 to move upward through the electric rotating shaft. Since the electric rotating shaft is in a self-locking state, the electric rotating shaft and the limiting wheel 13 cannot rotate. The upward movement of the limiting wheel 13 squeezes the limiting strip 12, and the limiting strip 12 moves to compress 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 of the charging gun 4 is stopped. At this time, under the action of the elastic force of the spring connected to the limiting strip 12, the triangular convex block on the limiting wheel 13 is inserted back into the corresponding triangular notch on the limiting strip 12. Under the limiting cooperation of the triangular convex block 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 guiding frame 6 again, keeping the first cable 3 at the extended length and preventing the first cable 3 from being on the ground during the charging process.

[0021] After the charging is completed, the operator unplug the charging gun 4 (if the charging gun 4 is not unplugged in time, the charging control module 2 starts timing after the charging is completed. When the set time is reached, the charging control module 2 controls the first electric push rod 11 to work, so that the charging gun 4 automatically disengages from the electric vehicle). Subsequently, the charging control module 2 controls the electric rotating shaft to work. Among them, the electric rotating shaft drives the limiting wheel 13 to rotate, and the limiting wheel 13 rotates and moves downward along the limiting strip 12. The limiting wheel 13 drives the sliding frame 9 to move downward through the electric rotating shaft. The downward movement of the sliding frame 9 causes the runner on it to squeeze the first cable 3, so that the first cable 3 and the charging gun 4 return to their initial states. When the electric vehicles at other positions need to be charged subsequently, the control cabinet 1 can be moved to the corresponding position.

[0022] In the service area, some charging piles move to the side of the vehicle for charging operations, and some charging piles are in the charging area. When the power of the charging pile in use is low, it is moved to the charging area for power replenishment, and the charging pile in the charging area is replaced to charge the remaining vehicles.

[0023] Embodiment 2: On the basis of Embodiment 1, refer to Figure 1 、 Figure 4 and Figure 5As shown in the figure, it further includes: a fixed seat 14, which is arranged on the ground. A socket is arranged inside the fixed seat 14, and the socket on the fixed seat 14 is connected to the power grid; a second cable 15, which is arranged on the cabinet 1. Plugs are arranged at both ends of the second cable 15. 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 be electrically connected to the socket on the fixed seat 14, facilitating the operator to select AC charging or DC charging on the charging pile. Multiple fixed seats 14 can be dispersedly arranged in the service area to facilitate charging operations in different areas of the service area.

[0024] The working process of this embodiment follows that of Embodiment 1 and is described in detail as follows: When it is necessary to use the charging pile to charge the vehicle, by controlling the electric wheels on the outriggers 5 to work, the charging pile is moved to a position close to the fixed seat 14. Subsequently, the plug on the second cable 15 is connected to the socket on the fixed seat 14, connecting the charging pile to the power grid. In this state, the charging pile can perform both DC charging and AC charging, increasing the charging mode. At the same time, the power grid replenishes the battery in the charging pile in real time. Subsequently, the vehicle is parked near the fixed seat 14, and the above vehicle charging operation can be repeated. This setting, combined with the movement of the charging pile, facilitates charging operations for vehicles in different positions of the service area. At the same time, this setting can move more charging piles to idle areas during peak periods, reducing vehicle congestion and the waiting time for everyone in line, improving the charging efficiency. At the same time, this setting greatly improves the convenience and practicality of using the charging pile.

[0025] Embodiment 3: On the basis of Embodiment 2, referring to Figures 4 - 6 As shown in the figure, it further includes: two symmetrically distributed second electric push rods 16 (the quantity is the quantity expression in the drawing). Both second electric push rods 16 are electrically connected to the charging control module 2, and both second electric push rods 16 are fixedly connected to the lower part of the cabinet 1; a sliding shell 17, which is slidably arranged inside the lower part of the cabinet 1. The telescopic end of the second electric push rod 16 is fixedly connected to the sliding shell 17; a second fixing frame 18, which is fixedly connected to the upper part of the sliding shell 17, and the second cable 15 is fixedly connected to the second fixing frame 18; two swing plates 19 are rotatably arranged at the upper part of the fixed seat 14 in a limited manner. The swing plates 19 cover the upper surface of the fixed seat 14. A torsion spring is installed between the swing plates 19 and the fixed seat 14, and the torsion spring is always in a twisted 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 in sealing fit with the fixed seat 14, and the three of them hermetically wrap the socket on the fixed seat 14. Two fixing plates 20 are fixedly connected to the second fixing frame 18, and the fixing plates 20 are used to squeeze the adjacent swing plates 19.

[0026] The working process of this embodiment follows that of Embodiment 2 and is described in detail as follows: In the initial state, the telescopic end of the second electric push rod 16 is in a contracted state. After the charging pile is controlled to move to directly above the fixed seat 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 operate. 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 fixing frame 18 and the two fixing plates 20 to move downward together. The fixing plate 20 moves downward to contact and squeeze the adjacent swing plate 19, causing the swing plate 19 to swing to release the shielding of the socket on the fixed seat 14 (the swing plate 19 will finally swing to a vertical state). Subsequently, the second fixing 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 seat 14. At this time, the sliding shell 17 contacts the ground and the second electric push rod 16 stops working, completing the connection of the charging pile to the power grid. The power grid charges the battery in the charging pile. When a vehicle needs to be charged subsequently, the above operation can be repeated.

[0027] Embodiment 4: On the basis of Embodiment 3, as shown in Figures 1 - 6 the fixed seat 14 is fixedly connected with four equally spaced limiting columns 21 (the quantity is the quantity expression in the attached drawing, and the actual quantity can be adjusted according to the actual situation). The upper side of the limiting column 21 is provided with an inclined surface. The second fixing frame 18 is fixedly connected with four equally spaced elastic telescopic rods 22. The lower ends of two adjacent elastic telescopic rods 22 are commonly fixedly connected with a fixing block 23. The fixing block 23 is provided with two blind holes. The diameter of the limiting column 21 is the same as the diameter of the blind holes on the fixing block 23. When the limiting column 21 is inserted into the corresponding blind hole on the adjacent fixing block 23, the socket on the fixed seat 14 is aligned with the corresponding plug on the second cable 15. The lower surface of the fixing block 23 is fixedly connected with two symmetrically distributed limiting plates 24. The distance between two adjacent limiting plates 24 is divided into three sections. The two outer sections are of variable diameter and the middle section is equally spaced. The limiting plates 24 are used to guide the movement of the adjacent limiting columns 21.

[0028] The working process of this embodiment follows that of Embodiment 3 and is described in detail as follows: During the process of the cabinet body 1 moving to directly above the corresponding fixed seat 14, the electric wheels on the support legs 5 work, first making the cabinet body 1 located behind the fixed seat 14 (in the attached Figure 4Taking the middle direction as an example), then control the cabinet body 1 to move forward. The movement of the cabinet body 1 drives the fixed block 23 and the limit plate 24 to move through the connected parts. During the movement of the cabinet body 1, the limit plate 24 contacts the limit post 21. Under the guiding action of the limit plate 24, the cabinet body 1 swings slightly until the cabinet body 1 moves directly above the fixed seat 14 (observed through the existing video detection unit, existing components not shown in the attached drawings). Stop the operation of the electric wheels on the legs 5, then control the telescopic end of the second electric push rod 16 to extend, and then repeat the operations in Embodiment 3. However, during this process, the second fixing frame 18 simultaneously drives the fixed block 23 to move downward through the elastic telescopic rod 22, so that the limit post 21 is inserted into the corresponding blind hole on the adjacent fixed block 23, improving the connection stability between the cabinet body 1 and the fixed seat 14, facilitating the automatic and precise insertion of the plug of the second cable 15 connected to the second fixing frame 18 into the socket of the fixed seat 14. For subsequent charging operations, repeat the operations in Embodiment 1 to form lumps. If the charging pile needs to be moved, perform the above reverse operations.

[0029] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation mode of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, based on the idea of this application, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
