Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a charging pile housing and a charging pile. Background Technology

[0002] The rapid development of the electric vehicle industry has increased the demand for charging stations, especially for outdoor charging stations where waterproof sealing and structural stability are crucial. To control costs and improve heat dissipation efficiency, some charging stations adopt a rear-opening design. However, this limits the space at the rear of the casing, preventing the use of traditional cabinet doors and forcing reliance on a removable back panel for internal access and sealing. To ensure casing sealing, a gasket is typically placed between the back panel and the casing mounting frame for waterproof sealing. However, in such designs, the gasket only covers a narrow edge on one side of the back panel mounting frame, forming a line contact or narrow band contact seal. This small contact area leads to pressure concentration at the sealing interface, easily causing localized over-compression, permanent deformation, or accelerated aging of the gasket. Especially with frequent back panel removal, seal failure is more likely, increasing maintenance costs and threatening the long-term operational reliability of the equipment in harsh outdoor environments. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a charging pile shell and charging pile with good sealing performance and high safety and reliability.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide a charging pile housing, comprising:

[0005] The body frame includes at least one receiving cavity and a connecting structure arranged circumferentially along the receiving cavity. The connecting structure includes a first connecting edge, a second connecting edge and a third connecting edge. The first connecting edge and the third connecting edge are arranged opposite to each other. The second connecting edge is disposed between the first connecting edge and the third connecting edge, and both ends of the second connecting edge are respectively connected to the first connecting edge and the third connecting edge.

[0006] A sealing gasket is disposed on the side of the third connecting edge away from the first connecting edge, and the projections of the second connecting edge and the third connecting edge in the horizontal direction are within the projection range of the sealing gasket in the same direction.

[0007] In the above-mentioned charging pile housing, the bottom edges of the first connecting edge and the third connecting edge are located on the same horizontal plane, one end of the second connecting edge is connected to the bottom of the first connecting edge, and the other end is connected to the bottom of the third connecting edge, and the projected area of ​​the sealing gasket in the horizontal direction is equal to the sum of the projected areas of the second connecting edge and the third connecting edge in the same direction.

[0008] In the aforementioned charging pile housing, a rear cover is included. The rear cover is detachably connected to the connecting structure via fasteners and can close the receiving cavity. One side of the sealing gasket abuts against the third connecting edge, and the other side abuts against the inner wall of the rear cover.

[0009] In the aforementioned charging pile housing, the first connecting edge, the second connecting edge, and the third connecting edge cooperate to form a first groove. The rear cover includes a shielding portion and a bent edge. The bent edge is arranged circumferentially along the shielding portion, with one end connected to the shielding portion and the other end extending away from the shielding portion. When the rear cover is installed on the main body frame, the projection of the extended end of the bent edge in the vertical direction is within the projection range of the first groove in the same direction.

[0010] In one of the above-mentioned charging pile housings, a horizontally arranged threaded post is provided on the first connecting edge. The threaded post extends along the connecting direction toward the third connecting edge, and the length of the threaded post is adapted to the width of the first groove.

[0011] In the above-mentioned charging pile housing, both the third connecting edge and the sealing gasket are provided with clearance notches. The clearance notches are arranged coaxially with the threaded post, and the shielding part is provided with a fixing hole coaxial with the threaded post. The fixing hole is recessed in the direction of the connecting structure, and the fastener can pass through the fixing hole and the clearance notch in sequence and then be connected to the threaded post.

[0012] In one of the charging pile housings described above, a second groove is provided on the side of the rear cover away from the receiving cavity, and the second groove is recessed along the outer wall of the rear cover toward the receiving cavity.

[0013] In the aforementioned charging pile housing, a first conductive contact portion is provided on the side of the first connecting edge facing the rear cover, and a second conductive contact portion is provided on the side of the rear cover facing the first connecting edge; when the rear cover is installed on the main body frame, the first conductive contact portion and the second conductive contact portion abut against each other and form an equipotential electrical connection path.

[0014] In the above-mentioned charging pile housing, the first conductive contact portion has a protrusion protruding from the surface of the first connecting edge, and the second conductive contact portion has a contact plane adapted to the shape of the protrusion, and the contact plane forms a surface contact with the protrusion.

[0015] The technical solution adopted by this utility model to solve its technical problem is to also provide a charging pile, which includes the above-mentioned charging pile shell.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In this invention, by setting a sealing gasket on the connecting structure of the housing, and ensuring that the projections of the second and third connecting edges along the horizontal direction are within the projection range of the sealing gasket in the same direction, the effective compression area of ​​the sealing gasket is significantly increased. Compared to the traditional line contact sealing method that only covers a single narrow edge, this design effectively increases the contact area of ​​the sealing interface, thereby enhancing the sealing performance and avoiding the problems of excessive compression, permanent deformation, or accelerated aging failure of the sealing gasket caused by local pressure concentration.

[0018] 2. In this invention, one end of the second connecting edge is perpendicularly connected to the bottom of the first connecting edge, and the other end is perpendicularly connected to the bottom of the third connecting edge. Furthermore, the projected area of ​​the sealing gasket in the horizontal direction is equal to the sum of the projected areas of the second and third connecting edges in the same direction. This design ensures uniform stress distribution on the sealing gasket, avoids localized excessive compression and accelerated aging, and further improves long-term sealing reliability.

[0019] 3. In this utility model, a first conductive contact portion is provided on the side of the first connecting edge facing the rear cover, and a second conductive contact portion is provided on the side of the rear cover facing the first connecting edge. When the rear cover is installed on the main frame, the first conductive contact portion and the second conductive contact portion abut against each other, forming an equipotential electrical connection path. This design achieves electrical connection by replacing traditional wires with mechanical structures, which not only saves the space required for grounding wires but also avoids potential hazards such as loosening, corrosion, or breakage of wires. Simultaneously, it effectively reduces contact impedance and improves the stability and safety of the electrical connection. Attached Figure Description

[0032] like Figures 1 to 4 As shown, in this embodiment, a charging pile housing includes:

[0033] The main body frame 100 includes at least one receiving cavity 110 and a connecting structure 200 arranged circumferentially along the receiving cavity 110. The connecting structure 200 includes a first connecting edge 210, a second connecting edge 220 and a third connecting edge 230. The first connecting edge 210 and the third connecting edge 230 are arranged opposite to each other. The second connecting edge 220 is disposed between the first connecting edge 210 and the third connecting edge 230, and both ends of the second connecting edge 220 are respectively connected to the first connecting edge 210 and the third connecting edge 230.

[0034] A sealing gasket 300 is disposed on the side of the third connecting edge 230 opposite to the first connecting edge 210, and the horizontal projections of the second connecting edge 220 and the third connecting edge 230 are within the projection range of the sealing gasket 300 in the same direction. Compared with the traditional line contact sealing method that only covers a single narrow edge, this design effectively increases the contact area of ​​the sealing interface, thereby enhancing the sealing performance and avoiding the problems of excessive compression, permanent deformation, or accelerated aging failure of the sealing gasket 300 due to local pressure concentration.

[0035] like Figures 1 to 4 As shown, in this embodiment, the charging pile housing adopts a split design, including a separately manufactured main frame and a rear cover 400. This design not only facilitates debugging and maintenance during production and assembly, but also improves the maintainability and scalability of the entire system through reasonable modular division. For example, when internal component upgrades or repairs are required, the internal equipment can be easily and quickly accessed simply by removing the rear cover 400, without disassembling the entire housing, greatly saving time and costs.

[0036] Furthermore, the main frame 100 includes multiple receiving cavities 110 for mounting various electronic components of the charging pile. Preferably, there are three receiving cavities 110 arranged in an equilateral triangular structure. This layout not only optimizes the utilization of internal space but also improves the stability of the overall structure.

[0037] Furthermore, the main frame 100 also includes a connecting structure 200 arranged circumferentially along the receiving cavity 110 for detachable connection with the rear cover 400. This connecting structure 200 includes multiple connecting edges, specifically a first connecting edge 210, a second connecting edge 220, and a third connecting edge 230. The first connecting edge 210 and the third connecting edge 230 are arranged opposite to each other, and the second connecting edge 220 is located between the first connecting edge 210 and the third connecting edge 230, with its two ends connected to both, forming a closed or semi-closed connecting profile, providing structural support and positioning reference for the installation of the rear cover 400.

[0038] Furthermore, both the first connecting edge 210 and the third connecting edge 230 are arranged vertically, and their bottom edges are located on the same horizontal plane to achieve structural alignment and improve overall assembly accuracy and appearance consistency. One end of the second connecting edge 220 is vertically connected to the bottom of the first connecting edge 210, and the other end is vertically connected to the bottom of the third connecting edge 230. Together, they form a U-shaped structural layout, enhancing the overall rigidity and load-bearing capacity of the connecting structure 200.

[0039] Furthermore, the first connecting edge 210, the second connecting edge 220, and the third connecting edge 230 cooperate to form an upward-facing first groove 240. This design serves two purposes: firstly, it can receive water droplets or condensation that may enter from the bent edge 420 of the rear cover 400 due to external environmental influences, preventing liquid from seeping into the housing along the bent edge 420, thereby improving overall protective performance; secondly, it provides space for the threaded post 211 or fixing hole 411 provided on the connecting structure 200, facilitating a secure connection of the rear cover 400 using fasteners 500 (such as screws or bolts), while preventing the threaded post 211 from protruding from the external contour and affecting the overall appearance and safety.

[0040] In this embodiment, the first connecting edge 210 has a horizontally arranged threaded post 211 on the side facing the rear cover 400. The threaded post 211 extends along the connecting direction toward the third connecting edge 230. The length of the threaded post 211 is adapted to the width of the first groove 240 to ensure that it can be completely accommodated in the first groove 240 during assembly, avoiding protrusion from the outer contour of the housing, thereby improving the compactness and neatness of the overall structure.

[0041] Preferably, the extension length of the threaded post 211 is designed to be slightly less than or equal to the width of the first groove 240, so that after the rear cover 400 is installed, the threaded post 211 is entirely within the space of the first groove 240, without interfering with the compression process of the sealing gasket 300, nor affecting the overall structural flatness and external protective performance. This design not only optimizes space utilization but also effectively prevents thread damage caused by collisions with external foreign objects, improving the product's durability and safety.

[0042] Furthermore, the threaded post 211 is used to mate with the fixing hole 411 on the rear cover 400, and the fastener 500 enables a detachable connection between the body frame 100 and the rear cover 400. Preferably, multiple threaded posts 211 are provided and are evenly distributed along the length direction of the first connecting edge 210 to ensure that the rear cover 400 is subjected to uniform force during the locking process, thereby improving the stability of the connection and the reliability of the seal.

[0043] In this embodiment, both the third connecting edge 230 and the sealing gasket 300 are provided with clearance notches 231. The clearance notches 231 are arranged coaxially with the threaded posts 211 to provide a channel for the fastener 500 to pass through. Preferably, there are multiple clearance notches 231, each corresponding to a threaded post 211, so that each threaded post 211 can be connected to the fastener 500 through the corresponding clearance notch 231.

[0044] Furthermore, the clearance notch 231 is circular, semi-circular, or rectangular. This not only ensures that the fastener 500 can smoothly pass through the sealing gasket 300 and the third connecting edge 230 to engage with the threaded post 211, but also accommodates the recessed fixing hole 411 on the rear cover 400. This allows the inwardly recessed portion of the fixing hole 411 to be accommodated within the clearance notch 231, achieving structural spatial coordination and functional optimization. Specifically, when the fixing hole 411 on the rear cover 400 adopts a countersunk hole or stepped hole design, a local recessed area will be formed on the side facing the main frame 100. To prevent this recessed area from interfering with the third connecting edge 230, the clearance notch 231 on the third connecting edge 230 and the sealing gasket 300 not only provides a passage for the fastener 500 but also provides space for the recessed portion of the countersunk hole structure, thereby achieving a seamless fit and flat connection between the rear cover 400 and the main frame 100.

[0045] Furthermore, the first connecting edge 210, the second connecting edge 220, and the third connecting edge 230 are manufactured using a one-piece molding process, such as sheet metal bending, die casting, or injection molding, and are integrated onto the main frame 100. This design significantly improves the structural strength and rigidity of the connecting area, reduces assembly errors, loose connections, or sealing failure risks caused by the splicing of multiple parts, while simplifying the production process and improving product consistency and manufacturing efficiency.

[0046] In this embodiment, the back cover 400 has a rectangular or T-shaped structure, and its overall shape is adapted to the opening shape of the receiving cavity 110 to ensure that the back cover 400 can achieve good alignment and fit during installation, thereby improving assembly accuracy and sealing performance.

[0047] Furthermore, the rear cover 400 is detachably connected to the connecting structure 200 via fasteners 500, thereby achieving reliable sealing of the receiving cavity 110. Preferably, the rear cover 400 has multiple covers, each corresponding to a different receiving cavity 110, so that each receiving cavity 110 can be independently closed and opened, facilitating independent maintenance or replacement of different functional modules and improving the maintainability and functional expandability of the system.

[0048] Furthermore, each back cover 400 includes a shielding portion 410 and a bent edge 420. The shielding portion 410 serves as the main body of the back cover 400, covering and sealing the receiving cavity 110. The bent edge 420 is arranged circumferentially along the shielding portion 410, with one end vertically connected to the shielding portion 410 and the other end extending horizontally away from the shielding portion 410 and extending above the first groove 240, thereby enhancing the edge strength of the back cover 400. When the back cover 400 is mounted on the body frame 100, the projection of the extended end of the bent edge 420 in the vertical direction falls within the projection range of the first groove 240 in the same direction. This design ensures that the bent edge 420 can be fully embedded within the first groove 240 during installation, without affecting the compression sealing performance of the sealing gasket 300 or exceeding the housing contour to cause uneven appearance or reduced protective performance. In addition, the design of the bent edge 420 and the first groove 240 helps to improve the compactness and aesthetics of the overall structure, while preventing foreign objects or liquids from entering the housing along the edge gaps.

[0049] Furthermore, the shielding part 410 is provided with a fixing hole 411 coaxial with the threaded post 211, for the fastener 500 to pass through, and to achieve a detachable connection with the threaded post 211 on the main body frame 100. Preferably, the fixing hole 411 is a countersunk hole, which has an inward structure on the side facing the connecting structure 200, so that the head of the fastener 500 can be completely embedded in the shielding part 410 after installation, without protruding from the outer surface of the back cover 400, thereby maintaining the flatness of the overall appearance and the compactness of the structure.

[0050] Furthermore, to improve user convenience and installation / removal efficiency, a second groove 430 is provided on the side of the back cover 400 away from the receiving cavity 110. The second groove 430 is recessed along the outer wall of the back cover 400 toward the receiving cavity 110, forming a recessed area that allows the user to hold or apply force, facilitating gripping, prying, or positioning operations during installation and removal.

[0051] Preferably, the opening of the second groove 430 has a rectangular outline and an arc-shaped transition surface inside to conform to the contact shape of human fingers, improve grip comfort and operation safety, and the arc-shaped surface design can also reduce stress concentration and avoid structural damage due to excessive local stress.

[0052] To further enhance the protective performance of the housing, in this embodiment, a sealing gasket 300 is also provided between the rear cover 400 and the main frame 100. Preferably, multiple sealing gaskets 300 are provided, each corresponding to one of the rear covers 400. The outline shape of each sealing gasket 300 is consistent with or adapted to the outline of the corresponding rear cover 400 to ensure full coverage and uniform compression during assembly, thereby improving the overall sealing performance and structural adaptability.

[0053] Furthermore, the sealing gasket 300 is disposed on the side of the third connecting edge 230 opposite to the first connecting edge 210, and the projections of the second connecting edge 220 and the third connecting edge 230 in the horizontal direction are within the projection range of the sealing gasket 300 in the same direction. This design significantly increases the effective compressive contact area between the sealing gasket 300 and the connecting structure 200, thereby improving the overall sealing performance.

[0054] Furthermore, the projected area of ​​the sealing gasket 300 in the horizontal direction is equal to the sum of the projected areas of the second connecting edge 220 and the third connecting edge 230 in the same direction. This design ensures that the compression of each area of ​​the sealing gasket 300 tends to be consistent under pressure, avoiding stress concentration, permanent deformation, or accelerated aging failure caused by excessive local compression, thereby improving the service life and long-term sealing reliability of the sealing gasket 300.

[0055] Furthermore, one side of the sealing gasket 300 abuts tightly against the end face of the third connecting edge 230, while the other side is in close contact with the inner wall surface of the rear cover 400, forming a complete sealing interface. During the tightening process of the fastener 500, the sealing gasket 300 is uniformly compressed, filling the gap between the rear cover 400 and the main body frame 100, thereby effectively preventing external dust, moisture, or foreign objects from entering the housing and ensuring the safe operation of the internal electronic components.

[0056] Preferably, the sealing gasket 300 is made of an elastic material, such as silicone rubber, EPDM (ethylene propylene diene monomer rubber) or foamed rubber, which has good compression resilience, weather resistance and anti-aging properties, and is suitable for long-term use in complex outdoor environments.

[0057] In this embodiment, to achieve an equipotential electrical connection between the main body frame 100 and the rear cover 400, and to improve the overall electromagnetic compatibility (EMC) and grounding safety of the housing, a first conductive contact 600 is provided on the side of the first connecting edge 210 facing the rear cover 400, and a second conductive contact 700 is provided on the side of the rear cover 400 facing the first connecting edge 210. When the rear cover 400 is installed on the main body frame 100, the first conductive contact 600 and the second conductive contact 700 abut against each other, forming an equipotential electrical connection path. This design replaces the traditional grounding wire with a mechanical structure to achieve electrical connection, which not only saves internal wiring space but also avoids potential fault risks such as loosening, corrosion, and breakage that may occur in wire connections, significantly improving the reliability and long-term operational stability of the electrical connection. In addition, while improving the electrical connection performance, this design can also effectively reduce contact impedance, preventing electromagnetic interference (EMI) or electrostatic discharge (ESD) problems caused by potential differences, thereby enhancing the housing's adaptability to the external electromagnetic environment and ensuring the normal operation of internal electronic components.

[0058] Furthermore, the first conductive contact 600 has a protrusion 610 extending beyond the surface of the first connecting edge 210. This protrusion 610 can be strip-shaped, arc-shaped, or multi-point distributed. Preferably, the protrusion 610 is a cylindrical metal protrusion with a certain height and contact area to ensure a stable contact interface with the second conductive contact 700. Correspondingly, the second conductive contact 700 has a contact plane 710 adapted to the shape of the protrusion 610, enabling surface contact rather than point or line contact during the installation of the rear cover 400. This surface contact significantly reduces contact resistance, improves conductivity, and enhances the stability and long-term reliability of the electrical connection.

[0059] Preferably, the first conductive contact 600 and the second conductive contact 700 are made of a metallic material with excellent conductivity, such as copper, aluminum, stainless steel, or plated metal parts, to ensure good conductivity and durability. Furthermore, to improve the conductivity stability and corrosion resistance of the contact surfaces, the contact surfaces may be treated with silver plating, nickel plating, or an anti-oxidation coating.

[0060] Based on the above-described embodiments of the charging pile housing, such as Figure 5 As shown, this utility model also provides a charging pile, which includes the aforementioned charging pile housing.
