Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to an outdoor electric vehicle charging pile. Background Technology

[0002] Electric vehicle charging stations are charging devices specifically designed for electric vehicles. They are typically installed in fixed locations such as residential areas, shopping malls, and streets. By connecting to the battery interface of the electric vehicle, they convert AC or DC power into power suitable for battery charging.

[0003] For example, an existing Chinese patent (CN212422864U) discloses an outdoor electric vehicle charging station, including a base plate. A second support frame is installed at the top center of the base plate, and first support frames are installed on both sides of the top of the base plate. A crossbar is installed between the first and second support frames. A charging station housing is bolted to the front surface of the second support frame, and a switch is installed on the front surface of the charging station housing. A metal flexible hose is bolted to the bottom of the crossbar, and an insulation board is installed at one end of the metal flexible hose. A heating wire is installed inside the insulation board. This invention uses the insulation board to increase the temperature around the battery, ensuring that the charging station can start normally and charge electric bicycles. The fixing plate avoids the traditional method of fixing the socket with bolts, which can cause the socket to loosen over time. This ensures the stability of the socket on the crossbar and guarantees the safe use of the socket.

[0004] Currently, most mainstream electric vehicle charging stations adopt a centralized, row-style layout, commonly found in open areas such as community carports and commercial parking lots. While this design facilitates unified management, the row-style charging stations are highly dependent on available space, requiring sufficient parking and passage space. In cities with numerous non-standard parking environments, the irregular spatial arrangement directly restricts the feasibility of implementing row-style charging stations, limiting installation to scattered individual charging stations at building corners, which is insufficient to meet the charging needs of multiple users. Therefore, this paper proposes an outdoor electric vehicle charging station. Utility Model Content

[0005] The purpose of this utility model is to provide an outdoor electric vehicle charging station to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor electric vehicle charging station, comprising: a column, a multi-faceted shell fixed to the outer wall of the column, a socket fixed to the outer wall of the multi-faceted shell, an open top of the multi-faceted shell, a top cover on the top of the multi-faceted shell, a base plate at the bottom of the column, supporting rods around the base plate, an isolation column at the top of the supporting rods, a wire hole inside the multi-faceted shell in the middle of the column, and an inspection port on one side of the bottom of the column.

[0007] Furthermore, the column is a hollow square tube, and wire holes are provided around the column inside the polyhedral shell.

[0008] Furthermore, the polyhedral shell is in the shape of a regular octahedron, the base plate is also in the shape of an octahedron, the supporting base rod is fixed to the outer side of the eight corners of the base plate, and a baffle is provided on the top of the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, through the design of a column, a polyhedral shell, and sockets, enables the use of outdoor electric vehicle charging stations. The polyhedral shell is fixed in the middle of the column, and multiple sockets are installed on the outer wall of the shell. Wires are threaded through the column's wiring holes to connect to external power for the sockets.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an outdoor electric vehicle charging station, comprising: a column 1, a polyhedral shell 7 fixed to the outer wall of the middle part of the column 1, and a socket 8 fixed to the outer wall of the polyhedral shell 7. The column 1 is a hollow square tube, and wire-passing holes 13 are provided around the column 1 inside the polyhedral shell 7. The polyhedral shell 7 is fixed to the outer wall of the middle part of the column 1 by welding or bolts. The hollow square tube structure of the column 1 reduces the weight of the column 1 and lowers material costs, while the hollow internal design provides space for wire passing; the polyhedral shell 7 serves as the mounting carrier for the socket 8, and its fixed position allows users to approach the socket from multiple directions, improving ease of use.

[0025] The top of the polyhedral housing 7 is open, and a top cover 12 is provided on the top of the polyhedral housing 7. The socket 8 is fixed to each face of the polyhedral housing 7 by screws; the top cover 12 is connected to the top opening of the polyhedral housing 7 by a snap-fit. The polyhedral structure, like a regular octahedron, allows a single charging pile to support 8 charging positions, reducing the floor space compared to traditional single-row charging piles; the top opening facilitates internal wiring, and the sealed design of the top cover 12 prevents rainwater from seeping in and damaging the socket 8 or the wiring.

[0026] The column 1 has a base plate 10 at its bottom, with supporting base rods 3 around the base plate 10 and an isolation column 4 at the top of the supporting base rods 3. The base plate 10 is welded to the bottom of the column 1; the supporting base rods 3 are fixed to the edge of the base plate 10; and the isolation column 4 is fixed to the top of the supporting base rods 3 with bolts. The base plate 10 and supporting base rods 3 increase the contact area between the column 1 and the ground, enhancing stability; the isolation column 4 forms a physical boundary, dividing the area into 8 independent charging zones, preventing vehicles from being placed haphazardly and occupying other charging spaces, and also preventing vehicles from being too close together and causing scratches.

[0027] A wiring hole 13 is provided in the middle of the column 1 inside the polyhedral shell 7, and an inspection port 9 is provided on one side of the bottom of the column 1. The wiring hole 13 is a hole drilled in the side wall of the column 1 and communicates with the internal hollow channel; the inspection port 9 is a cut opening in the side wall of the column 1 and is covered with an inspection door. The wiring hole 13 allows the power line to be concealed from inside the column to the polyhedral shell 7, avoiding aging or human damage to the exposed line; the inspection port 9 facilitates regular maintenance of the internal line or controller and reduces the difficulty of maintenance.

[0028] The polyhedral shell 7 is octahedral in shape, as is the base plate 10. Support rods 3 are fixed to the outer sides of the eight corners of the base plate 10, and a baffle 2 is provided on the top of the base plate 10. The base plate 10 and the polyhedral shell 7 are synchronously fixed to the column 1 with bolts, and the support rods 3 are welded to the eight corners of the base plate 10. The octahedral structure matches the number of sockets, ensuring that each face corresponds to one charging position; the octahedral design of the base plate 10 disperses the stress at the bottom of the column, forming a stable support in conjunction with the support rods 3. The baffle 2 surrounds the bottom of the column 1 to prevent vehicles from directly impacting the column 1.

[0029] The top of the cover 12 is equipped with an upper flange, the inner wall of which fits against the outer wall of the column 1. The upper flange is a ring structure, fitted onto the top outer wall of the column 1 and fixed with sealant. The fitting design between the upper flange and the column 1 forms a double seal, preventing rainwater from seeping into the interior of the polyhedral housing 7 from the top, protecting the socket 8 and wiring; at the same time, the cover 12 is removable, facilitating future upgrades to the socket or repair of internal components.

[0030] There are eight sockets 8, which are fixed to the eight faces of the polyhedral housing 7. Each socket 8 is fixed to the corresponding face of the polyhedral housing 7 by an independent screw, and the wiring is led out from the wire hole 13 and branched. The eight sockets enable "one pile for multiple charging", which can meet the charging needs of eight electric vehicles at the same time during peak hours; the polyhedral layout makes the charging positions radially distributed, allowing for flexible vehicle parking angles and reducing queuing time.

[0031] An inspection door is hinged to the outside of the inspection port 9, and a cover is provided at the top of the column 1. The inspection door is connected to the edge of the inspection port 9 by a hinge; the cover is made of rubber or plastic and is inserted into the opening at the top of the column 1.

[0032] A photovoltaic module housing 5 is fixed to the top outer wall of the column 1. A support strip 11 is provided on the bottom outer wall of the photovoltaic module housing 5. A photovoltaic panel 6 is mounted on top of the support strip 11. Multiple photovoltaic panels 6 are arranged circumferentially and evenly on the outside of the column 1. The photovoltaic module housing 5 is used to install photovoltaic modules, which include at least a controller and an inverter. The photovoltaic module housing 5 is fixed to the top of the column 1 by bolts; the support strip 11 is welded to the bottom outer wall of the housing 5; the photovoltaic panels 6 are fixed to the top of the support strip 11 by bolts. The photovoltaic module housing 5 protects the internal controller, inverter, and other components; the support strip 11 supports the photovoltaic panels 6, forming an air circulation channel to reduce the impact of high temperatures on power generation efficiency; the circumferentially arranged photovoltaic panels 6 maximize the use of sunlight from all around the column. The controller and inverter are fixed inside the photovoltaic module housing 5 by rails or screws, and their wiring is connected to the photovoltaic panels 6 and the mains power system. The controller enables maximum power point tracking of the photovoltaic panel 6, and the inverter converts DC power to AC power to supply socket 8 or connect it to the grid. The dual power supply mode of photovoltaic modules and mains power reduces operating costs, while the shading function of the photovoltaic panel 6 reduces the surface temperature of the charging pile and extends the equipment life.

[0033] This utility model, through the design of a column, a polyhedral shell, and sockets, enables the use of outdoor electric vehicle charging stations. A polyhedral shell 7 is fixed in the middle of the column 1, and multiple sockets 8 are installed on the outer wall of the polyhedral shell 7. Wires are threaded through the wire hole 13 of the column 1 to connect to external power supply for the sockets 8. The top of the polyhedral shell 7 is sealed and protected by the top cover 12. The bottom support rod 3 and isolation column 4 isolate and divide the bottom area, allowing for the division of areas with the same number of faces of the polyhedral shell 7 on the outer side of the column 1. This facilitates simultaneous charging of electric vehicles using their respective sockets 8 within their designated areas. For rows of charging stations, this design reduces the footprint while allowing multiple charging positions to be set on a single column 1, making it convenient for users.

[0034] By installing photovoltaic panels 6 and photovoltaic modules on the column 1, the photovoltaic panels 6 can provide outdoor rain and sun protection, while the power generation of the photovoltaic panels 6 can improve the economic efficiency of the charging pile.

[0035] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
