Technical Field

[0001] This application relates to the field of vehicle charging technology, specifically to a sealing structure, a charging system, and a vehicle. Background Technology

[0002] With the increasing popularity of electric vehicles, the demands for efficiency and intelligence in charging infrastructure are rising. Fast charging connectors and Intelligent Power Distribution Units (IPDUs), as key components of electric vehicle charging systems, are of great significance in their technological development and application. The combined use of fast charging connectors and IPDUs enables efficient charging and intelligent energy management. The fast charging connector is responsible for quickly and safely transmitting external electrical energy to the electric vehicle, while the IPDU is responsible for rationally distributing electrical energy to various loads, ensuring that each device receives the necessary power and improving energy utilization efficiency.

[0003] For known electric vehicles, the intelligent power distribution unit is usually located outside the passenger compartment of the vehicle. The fast charging connector needs to be extended through the vehicle floor to connect to the intelligent power distribution unit outside the passenger compartment, and the mounting holes on the vehicle floor are sealed by a sealing structure set on the wiring harness of the fast charging connector.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0025] It is readily understood that, based on the technical solution of this application, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of this application.

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used for descriptive and distinguishing purposes only and should not be construed as indicating or implying the relative importance of the corresponding components or the order of components or assembly sequence.

[0027] One aspect of this application proposes a sealing structure 100 that enables a seal between the intelligent power distribution unit 300 and the vehicle chassis 400. (Reference) Figure 1 This illustration shows a schematic diagram of a sealing structure 100 according to one embodiment of this application. The sealing structure 100 is configured as annular and can be arranged within an annular groove 302 surrounding the male connector 301 on the intelligent power distribution unit 300. It should be understood that the term "annular" in this application refers to a hollow, closed geometric structure, which can be square, rectangular, circular, etc., and all of these should be included within the concept of "annular" in this application. Figure 1 In the implementation of the invention, the sealing structure 100 is in the shape of a "square ring". Of course, the sealing structure 100 can also be other types of ring shapes, such as rectangular, circular or elliptical shapes, which should also be included in the protection scope of this application.

[0028] In one embodiment of this application, a first sealing element 110 is provided on the upper surface of the sealing structure 100 for sealing in the axial direction of the sealing structure 100, and a second sealing element 120 is provided on the outer periphery of the sealing structure 100 for sealing in the radial direction of the sealing structure 100. Further, the first sealing element 110 is a first sealing ring, and the second sealing element 120 is a second sealing ring. Further, a first annular recess 101 is provided on the upper surface of the sealing structure 100, the first sealing ring is disposed in the first annular recess 101 and at least partially protrudes outward from the first annular recess 101, and a second annular recess 102 is provided on the outer periphery of the sealing structure 100, the second sealing ring is disposed in the second annular recess 102 and at least partially protrudes outward from the second annular recess 102. In this way, the sealing ring can be tightly abutted against its adjacent mounting plane, ensuring a sealing effect.

[0029] In one embodiment of this application, the first sealing ring is interference-fitted with the first annular recess 101, and the second sealing ring is interference-fitted with the second annular recess 102, so that the position between the sealing ring and the recess remains relatively fixed and is not prone to relative slippage during assembly. For example, protrusions (not shown in the figures) or raised points are provided in the first annular recess 101 and the second annular recess 102, and recesses, such as pits, that match the protrusions are provided on the first sealing ring 110 and the second sealing ring 120. This not only facilitates the positioning of the sealing ring and the annular recess during installation, but also helps to fix their position.

[0030] In one embodiment of this application, an annular recess 103 is provided on the sealing structure 100, recessed from the lower surface of the sealing structure 100. This recess 103 is particularly advantageous for saving material and reducing the overall weight of the sealing structure 100 during manufacturing, especially during injection molding. Furthermore, reinforcing ribs (not shown in the figures) are provided in the recess 103 at intervals, which are injection molded integrally with the sealing structure 100, for example, to enhance the overall strength of the sealing structure 100.

[0031] The sealing structure 100 is provided with threaded mounting holes 104 for mounting onto the vehicle body floor 400. When the sealing structure 100 is screwed onto the vehicle body floor 400 with bolts, the first sealing ring gradually comes into contact with, or even is pressed against, the lower surface of the vehicle body floor 400, thereby achieving an effective seal. This sealing effect can also be adjusted using bolts.

[0032] A second aspect of this application provides a charging system 10, which includes a charging connector 200, an intelligent power distribution unit 300, and the aforementioned sealing structure 100, wherein the charging connector 200 is, in particular, a fast charging connector. (Reference) Figure 2 and Figure 3 The diagrams show exploded views of the intelligent power distribution unit 300 and the sealing structure 100, as well as a cross-sectional view of the charging system 10 as a whole. Figure 2 As can be seen, a protruding male connector 301 is mounted on the intelligent power distribution unit 300, and an annular groove 302 is provided on the intelligent power distribution unit 300 around the male connector 301, with the sealing structure 100 arranged in the annular groove 302. A female connector (not shown in the figure) is provided on the charging connector 200 to mate with the male connector 301, and the charging connector 200 is inserted into the male connector 301 on the intelligent power distribution unit 300 through the female connector.

[0033] In known charging systems, the charging connector typically needs to extend under the vehicle floor 400 to connect to the intelligent power distribution unit. However, because the charging connector is a female connector, its large size results in a large opening in the vehicle floor, affecting the vehicle's structural strength. In this installation method, the sealing structure is usually located on the charging connector's wiring harness, and the connector is further installed into the mounting hole after being connected to the intelligent power distribution unit, making installation difficult and impacting overall assembly efficiency. The charging system 10 of this application eliminates the need for the charging connector 200 to extend under the vehicle floor 400 to connect to the intelligent power distribution unit 300. Instead, the male connector 301 of the intelligent power distribution unit 300 can be directly inserted into the passenger compartment to connect to the charging connector 200. Since the male connector 301 is smaller than the female connector, this reduces the size of the mounting hole 401 in the vehicle floor 400. The sealing structure 100 in the charging system 10 can also be pre-arranged in the intelligent power distribution unit 300. After the charging connector 200 is connected to the intelligent power distribution unit 300, it can be bolted from above the vehicle body floor 400, making assembly simple and convenient.

[0034] After the intelligent power distribution unit 300, the charging connector 200 and the sealing structure 100 are installed on the vehicle body floor 400, the upper surface of the sealing structure 100 is flush with the groove of the annular groove 302, so that the upper surface of the sealing structure 100 can be attached to the lower surface of the vehicle body floor 400.

[0035] In one embodiment of this application, the first sealing element 110 is a first sealing ring, and the second sealing element 120 is configured as a second sealing ring. The outer peripheral surface and the inner peripheral surface of the sealing structure 100 respectively abut against the inner and outer annular inner walls of the annular groove 302, so that the second sealing ring abuts against the outer inner wall of the annular groove 302, making it difficult for moisture and dust outside the passenger compartment to enter the mounting hole 401 of the vehicle floor 400 through the gap between the sealing structure 100 and the intelligent power distribution unit 300.

[0036] A third aspect of this application also proposes a vehicle comprising a chassis 400 and the aforementioned charging system 10. (See again...) Figure 3 A mounting hole 401 is provided on the vehicle body floor 400. The male connector 301 of the intelligent power distribution unit 300 extends from below to above the vehicle body floor 400 through this mounting hole 401. Therefore, the size of the mounting hole 401 is specifically designed to approximate the length and width dimensions of the male connector 301 in the horizontal direction, and is specifically equivalent to that dimension plus the mounting gap. The female connector on the charging connector 200 connects to the male connector 301 above the vehicle body floor 400. The sealing structure 100 is provided below the vehicle body floor 400, and its upper surface is in particular abutting against the lower surface of the vehicle body floor 400.

[0037] In one embodiment of this application, the first sealing element 110 is a first sealing ring, and the second sealing element 120 is a second sealing ring. The first sealing ring abuts against the vehicle body floor 400, and the second sealing ring abuts against the inner wall of the annular groove 302. Thus, the mounting hole 401 is doubly sealed on the underside of the vehicle body floor 400 by the sealing structure 100. This prevents water or dust from entering the mounting hole 401 through the gap between the intelligent power distribution unit 300 and the vehicle body floor 400 in the axial direction, and also prevents water or dust from directly entering the mounting hole 401 through the gap between the sealing structure 100 and the vehicle body floor 400 in the radial direction, achieving effective sealing.

[0038] In one embodiment of this application, a threaded mounting hole 104 is provided on the sealing structure 100, and a through hole matching the threaded mounting hole 104 is provided on the vehicle body floor 400. The sealing structure 100 is fixed to the vehicle body floor 400 by bolts through the threaded mounting hole 104 and the through hole. With this bolt installation method, when the vehicle body floor 400 is connected to the sealing structure 100 located in the annular groove 302 by bolts, the sealing structure 100, especially the first sealing ring, can automatically and gradually conform to the lower surface of the vehicle body floor 400 as the bolts are tightened, ensuring a radial seal.

[0039] One embodiment of this application proposes a charging system that eliminates the need for the charging connector to extend under the vehicle floor to connect with the intelligent power distribution unit. Instead, the male connector of the intelligent power distribution unit can be directly inserted into the passenger compartment to connect with the charging connector, reducing the size of the mounting holes in the vehicle floor and facilitating the assembly of the charging system. The charging system also includes a sealing structure for sealing between the vehicle floor and the intelligent power distribution unit. This structure is simple, easy to install, and can ensure effective sealing of the mounting holes in the vehicle floor from two directions, preventing water or dust from entering the passenger compartment through the mounting holes.

[0040] It should be understood that all the above preferred embodiments are exemplary and not restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the scope of legal protection of this application.
