Technical Field
[0001] The present invention relates to the technical field of battery vehicle charging piles, and in particular to a lifting type battery vehicle charging pile. Background Art
[0002] In today's urban environment, electric vehicles have been widely used as a convenient means of transportation; however, existing electric vehicle charging piles have shown deficiencies in many aspects; taking old residential areas as an example, the space is limited, and some existing charging piles are usually a large device fixed on the ground, occupying a certain space, which makes the originally narrow residential roads narrower, affecting the normal passage of pedestrians. At the same time, when parking vehicles in the residential area, these charging piles may also hinder the parking of vehicles, resulting in parking difficulties; in commercial areas, the flow of people and vehicles is large, and existing charging piles often occupy valuable commercial space, which not only affects the shopping experience of pedestrians, but also may hinder the normal progress of commercial activities. For example, in the parking lot of a shopping mall, fixed charging piles may occupy some parking spaces, resulting in more tense parking spaces; such as in tourist attractions and high-end residential areas, the requirements for landscape are very high. The existing charging piles, due to their fixed form and relatively monotonous appearance, can easily destroy the overall aesthetics. In tourist attractions, these charging piles may be incompatible with the surrounding natural or cultural landscapes, affecting the tourists' tour experience. In high-end residential areas, fixed charging piles may reduce the grade and quality of the community.
[0003] In order to solve the above problems, it is particularly important to design a liftable battery vehicle charging pile. When not in use, the charging pile can be lowered and hidden below the ground, without taking up any space, and will not affect pedestrian traffic, vehicle parking and the overall layout and aesthetics of the community. When needed, the charging pile can be raised to provide charging services for the battery vehicle. Such a design not only meets the needs of battery vehicle charging, but also solves the space and aesthetic problems of existing charging piles.

DETAILED DESCRIPTION
[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0032] like Figure 1-6 As shown, a lifting type battery vehicle charging pile comprises a ground 1, a charging module 4 and ten lifting type pile bodies 3. A groove is excavated on the ground 1 for burying and installing the charging module 4 and the ten lifting type pile bodies 3. A cover plate 2 is installed at the opening of the groove. The charging module 4 is connected to a main transmission cable 8 for connecting the ten lifting type pile bodies 3. The groove is rectangular as a whole, and reinforced concrete is poured on the four walls of the groove for reinforcement. Whether the bottom surface of the groove needs to be treated for water seepage, in real life, the pile body of the battery vehicle charging pile does not exceed More than one meter, that is to say, the height of the lifting pile body 3 generally does not exceed one meter, so it can be determined that the depth of the groove is about one meter, which is not deep, and there is rarely backflow or water seepage. It can be directly compacted and then covered with a layer of gravel to increase the supporting strength. If there is frequent backflow and water seepage on the bottom surface of the groove, it is necessary to dig a deeper hole at one end of the groove for drainage to avoid water accumulation in the groove, which will affect the lifting pile body 3 installed in the groove, the charging module 4 and the main transmission cable 8 to be connected.
[0033] It should be noted that the charging module 4 is the core part of the charging pile, which specifically adopts the charging control box of the 10-way charging pile for battery vehicles in the prior art, which is mainly composed of a charger, a controller, and a power supply. The charger is responsible for converting the input AC power into DC power suitable for charging the battery vehicle. The controller adjusts the charging current, voltage and other parameters according to the charging demand and status of the battery vehicle to ensure the safety and stability of the charging process. The power supply provides power to the charging module 4 to ensure its normal operation.
[0034] The charging module 4 constituted by the charging control box of the above-mentioned 10-way charging pile for electric vehicles has a display screen for displaying information such as the status of the charging pile, charging progress, and charging fees. A QR code for scanning and charging is also provided on one side of the display screen. The end face of the charging module 4 having the display screen and the QR code for scanning and charging is vertically facing upward and fitted on the lower surface of the cover plate 2. An observation window for observing the charging module 4 is provided on the cover plate 2.

When it rains, the rain shield 305 can directly block most of the rain falling vertically from above, preventing the rain from directly pouring on the socket 306. The rain shield 305 is circular, and a number for distinguishing the position and a QR code for scanning and charging are provided on the upper surface of the rain shield 305. A push switch for controlling the push rod 311 in the linear electric cylinder 301 to retract and descend downward is also installed on the upper surface of the rain shield 305. The outer diameter of the rain shield 305 is larger than the outer diameter of the electrical box 304, so that the cross-sectional area of the rain shield 305 is larger than the cross-sectional area of the electrical box 304.

[0049] After receiving the charging signal, the charging module 4 transmits an ascending signal to the lifting pile body 3 to be charged, exposing the socket 306 at the top of the lifting pile body 3, which can meet the user's instant charging needs and improve the convenience of charging.
[0050] 3) Use a battery charger to connect the battery to the socket 306 at the top of the raised lifting pile body 3 for charging;
[0051] If the user is worried about the battery vehicle charger getting wet in the rain, the user can pull out the telescopic plate 307 and the connecting frame 308 and place the battery vehicle charger in the connecting frame 308, which can effectively prevent the battery vehicle charger in the connecting frame 308 from getting wet, ensuring that the user can use the lifting battery vehicle charging pile normally outdoors on rainy days.
[0052] 4) After charging is completed, unplug the battery charger connected to the socket 306, push the telescopic plate 307 and the connecting frame 308 in and retract them, then scan the QR code on the top of the lifting pile body 3 with a mobile phone to issue a descending and retracting command to the linear electric cylinder 301, or press the push switch on the lifting pile body 3 to gradually move the electric box 304, the telescopic plate 307 and the rain shield 305 downward, and press on the second ring 502, the third ring 503, and the fourth ring 504 in turn, until the upper surface of the rain shield 305 is embedded in the inner circle of the first ring 501 and is consistent with the upper surface of the cover plate 2 for sealing.
[0053] According to the present invention, when the ten lifting pile bodies 3 in the lifting battery vehicle charging pile are not in use, the lifting pile bodies 3 are lowered and hidden in the grooves, which can minimize the occupation of ground space. In areas with tight space, such as old residential areas, commercial areas, etc., it can avoid affecting pedestrian traffic, vehicle parking or other activities due to the occupation of the lifting pile bodies 3, and effectively improve the space utilization rate. For some places with high requirements for landscape, such as tourist attractions, high-end residential areas, etc., the hidden lifting pile bodies 3 will not destroy the overall aesthetics, making the environment more tidy and orderly. The number and layout of the lifting pile bodies 3 can be flexibly adjusted according to actual usage. For example, in areas with large traffic, the number of lifting piles can be increased to meet the charging needs of more users. In areas with limited space, the position of the lifting piles can be reasonably planned so that it does not affect other activities and is convenient for users to use.
[0054] When the lifting pile body 3 is lifted vertically, the sealing connector 5, which is coaxially sealed and telescopically connected by the first ring 501, the second ring 502, the third ring 503 and the fourth ring 504 from the outside to the inside, can ensure that the cover plate 2 and the sleeve 303 are always in a sealed state, prevent dust, debris and moisture from entering the groove, protect the charging module 4, the main transmission cable 8, the linear electric cylinder 301, the branch cable 302 and other electrical components in the groove, and extend the service life of the entire lifting battery vehicle charging pile.
