The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 3As shown, an embodiment of the vehicle charging interface structure 10 disclosed herein includes a vehicle charging female connector mounting plate 100, a vehicle charging DC female connector assembly 200, and a vehicle charging female connector fixing bracket 300. The vehicle charging female connector mounting plate 100 has a charging hole 1001. The vehicle charging DC female connector assembly 200 is disposed on the vehicle charging female connector mounting plate 100.

[0030] The car charger female connector fixing bracket 300 is connected to the car charger female connector mounting plate 100. The car charger female connector fixing bracket 300 is sleeved on the car charger DC female connector assembly 200. The car charger female connector fixing bracket 300 has a female connector wire passage hole and a female connector heat dissipation hole 3001. The female connector wire passage hole is connected to the female connector heat dissipation hole 3001 and the charging hole 1001 respectively. The connecting wires of the car charger DC female connector assembly 200 pass through the female connector wire passage hole to be electrically connected to the output terminal of the battery module. The female connector heat dissipation hole 3001 is correspondingly provided with the heat dissipation part of the car charger DC female connector assembly 200. The female connector heat dissipation hole 3001 is used to conduct heat out of the car charger DC female connector assembly 200. The charging terminal of the car charger DC female connector assembly 200 is exposed in the charging hole 1001 to be electrically connected to the charging terminal of the electrical device.

[0031] In this embodiment, when assembling the vehicle charging interface structure 10, the vehicle charging DC female connector assembly 200 must first be installed on the vehicle charging female connector mounting plate 100, ensuring that the vehicle charging DC female connector assembly 200 corresponds to the charging hole 1001 on the vehicle charging female connector mounting plate 100. Then, the vehicle charging female connector fixing bracket 300 is sleeved on the vehicle charging DC female connector assembly 200, and the vehicle charging DC female connector assembly 200 is connected and fixed to the vehicle charging female connector mounting plate 100 by fasteners, so that the vehicle charging female connector mounting plate 100, the vehicle charging DC female connector assembly 200, and the vehicle charging female connector fixing bracket 300 form an integral structure, which facilitates the fixing and disassembly of the vehicle charging interface structure 10. When the device needs charging, its charging end is inserted into the DC charging connector 200 through the charging port 1001, establishing an electrical connection. This allows the energy from the storage battery to be transferred to the device via the DC charging connector 200 and its connecting wires, thus enabling the vehicle charging interface structure 10 to perform its charging function. Furthermore, during operation, the DC charging connector 200 generates heat. To maintain its operating temperature within a safe range, the heat dissipation holes 3001 effectively dissipate the heat to the external environment, preventing overheating and potential injury to operators. On the other hand, the connecting wires of the DC charging connector 200 pass through the wire holes in the mounting bracket 300, preventing the wires from becoming tangled within the bracket and allowing for multiple cable exit methods, thereby improving the applicability of the vehicle charging interface structure 10.

[0032] The aforementioned vehicle charging interface structure 10 integrates the vehicle charging DC female connector assembly 200, the vehicle charging female connector mounting plate 100, and the vehicle charging female connector fixing bracket 300 into a single structure, which improves the assembly and disassembly efficiency and stability of the vehicle charging interface structure 10. Furthermore, the female connector heat dissipation hole 3001 provided in the vehicle charging female connector fixing bracket 300 effectively enhances the heat dissipation efficiency of the vehicle charging DC female connector assembly 200 and reduces the risk of operator injury due to overheating. In addition, because the vehicle charging female connector fixing bracket 300 has a female connector cable passage hole, and the connecting wires of the vehicle charging DC female connector assembly 200 pass through the female connector cable passage hole, the vehicle charging interface structure 10 is compatible with various wiring methods. This allows the connecting wires of the vehicle charging DC female connector assembly 200 to be used with different battery module wiring connection methods, thereby improving the adaptability of the vehicle charging interface structure 10.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the female connector cable passage includes at least one top main cable passage 3002. The top main cable passage 3002 is located on the side of the vehicle charger female connector fixing bracket 300 opposite to the vehicle charger female connector mounting plate 100. The top main cable passage 3002 is used to pass through the positive wire of the vehicle charger DC female connector assembly 200. In this embodiment, after the vehicle charger DC female connector assembly 200 is installed on the vehicle charger female connector mounting plate 100, its positive wire passes through the top main cable passage 3002 and connects to the positive output terminal of the battery module to realize power transmission. This avoids the wire from getting tangled inside the vehicle charger female connector fixing bracket 300, thereby effectively reducing installation difficulties or potential safety hazards caused by wire interference. Furthermore, the design of the top main cable passage 3002 enhances the versatility of the vehicle charging interface structure 10. Furthermore, since the size and position of the positive wires of different battery modules may vary, the flexible wiring method of the top main wire hole 3002 can adapt to the positive wire connection requirements of various battery modules, thereby improving the compatibility and applicability of the entire vehicle charging interface structure 10.

[0034] like Figure 2As shown, in one embodiment, the car charger DC connector assembly 200 includes a car charger DC conductive cylinder 210 and a car charger DC conductive component 220. The car charger DC conductive cylinder 210 includes a DC conductive negative electrode cylinder 211 and a DC conductive positive electrode cover 212 that are insulated from each other. The car charger DC conductive component 220 includes a main charging terminal 221, a main charging positive electrode wire 222, and a main charging negative electrode wire 223. The positive electrode of the main charging terminal 221 is electrically connected to the DC conductive positive electrode cover 212 through the main charging positive electrode wire 222, and the negative electrode of the main charging terminal 221 is electrically connected to the DC conductive negative electrode cylinder 211 through the main charging negative electrode wire 223. In this embodiment, the car charger DC conductive cylinder 210 serves as the main structure of the connector assembly. Its DC conductive negative electrode cylinder 211 and DC conductive positive electrode cover 212 are isolated from each other by insulating material, ensuring electrical safety between the positive and negative electrodes and effectively preventing short circuits. The DC conductive negative electrode cylinder 211 not only serves as a conductive channel for the negative electrode but also provides mechanical support and positioning for the inserted charging terminal, thereby ensuring stability during the charging process. The positive terminal of the main charging terminal 221 in the car charger's DC conductive component 220 is tightly connected to the DC conductive positive electrode cover 212 via the main charging positive electrode line 222, forming a positive current path from the positive electrode of the battery module to the positive electrode of the electrical device. Simultaneously, the negative terminal of the main charging terminal 221 is connected to the DC conductive negative electrode cylinder 211 via the main charging negative electrode line 223, forming a negative current loop, thus enabling electrical energy to be transferred from the battery module to the electrical device.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the female connector heat dissipation hole 3001 is located on the side of the car charger female connector fixing bracket 300, and the female connector heat dissipation hole 3001 is adjacent to at least one top main cable pass hole 3002. In this embodiment, when the car charger DC female connector assembly 200 establishes an electrical connection with the electrical device and begins charging, a certain amount of heat is generated due to the passage of current and the operation of internal electronic components. If the heat cannot be dissipated in time, the temperature of the car charger DC female connector assembly 200 may rise, thereby affecting its performance and lifespan. Since the female connector heat dissipation hole 3001 is located on the side of the car charger female connector fixing bracket 300, adjacent to at least one top main cable pass hole 3002, and the heat dissipation hole is close to the heat source of the car charger DC female connector assembly 200, an effective heat dissipation channel is formed. Specifically, when the DC connector assembly 200 of the car charger is working, the heat generated is transferred to the car charger connector mounting bracket 300 through heat conduction. At this time, the heat dissipation holes allow air to circulate and use convection to carry the heat of the DC connector assembly 200 of the car charger out of the heat dissipation holes and dissipate it into the external environment, thereby reducing the temperature of the DC connector assembly 200 of the car charger and avoiding damage to the operator caused by high temperature.

[0036] like Figure 2 andFigure 3 As shown, in one embodiment, the number of female connector heat dissipation holes 3001 is multiple, and the multiple female connector heat dissipation holes 3001 are arranged around at least one top main cable passage hole 3002. In this embodiment, the multiple heat dissipation holes arranged around at least one top main cable passage hole 3002 enhance the heat dissipation effect of the heat dissipation holes and improve the uniformity of heat dissipation. When the car charger DC female connector assembly 200 establishes an electrical connection with the electrical device and starts charging, a large amount of heat is generated due to the flow of current and the operation of internal electronic components. This heat is first transferred to the car charger female connector fixing bracket 300 by thermal conduction, and then dissipated by means of the female connector heat dissipation holes 3001. At this time, the multiple female connector heat dissipation holes 3001 are arranged around the top main cable passage hole 3002, so that heat can be dissipated from multiple directions simultaneously, and the heat generated by the car charger DC female connector assembly 200 can be dissipated to the external environment more quickly and evenly, further improving the heat dissipation efficiency.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the female connector cable passage further includes at least one first side cable passage 3003, which is connected to the top main cable passage 3002. The first side cable passage 3003 is used to pass through the negative wire of the vehicle charger DC female connector assembly 200 and / or the series-parallel connection wire of the vehicle charger DC female connector assembly 200. In this embodiment, the first side cable passage 3003 is connected to the top main cable passage 3002, providing an additional cable passage for the negative wire or the series-parallel connection wire of the vehicle charger DC female connector assembly 200. After the DC female connector assembly 200 of the vehicle charger is installed on the mounting plate 100 of the vehicle charger, its negative wire can be passed through the first side wire hole 3003, which makes the routing of the negative wire more flexible. The most suitable wiring method can be selected according to the layout and space constraints of the vehicle interior, thus avoiding the wire from getting tangled inside the vehicle charger mounting bracket 300 or inside the vehicle, reducing installation difficulty and potential safety hazards. At the same time, the first side wire hole 3003 can also be used to pass through the series and parallel connection wires of the DC female connector assembly 200 of the vehicle charger. In the on-board charging system, when multiple battery modules or charging interfaces need to be connected in series or in parallel, the series and parallel connection wires can be introduced or led out through the first side wire hole 3003 to meet different power transmission requirements, thereby realizing flexible connection between the on-board charging interface structure 10 and other battery modules or charging interfaces.

[0038] like Figure 2 and Figure 3As shown, in one embodiment, the female connector cable passage further includes at least one second side cable passage 3004. The second side cable passage 3004 is located on the side of the first side cable passage 3003 away from the top main cable passage 3002. The second side cable passage 3004 is used to pass through the negative wire of the car charger DC female connector assembly 200. In this embodiment, the second side cable passage 3004 is located on the side of the first side cable passage 3003 away from the top main cable passage 3002, providing another independent cable passage for the negative wire of the car charger DC female connector assembly 200. During the assembly of the vehicle charging interface structure 10, the negative wire of the vehicle charging DC female connector assembly 200 can be selected to pass through the first side wire hole 3003 or the second side wire hole 3004 according to the wiring requirements and space layout inside the vehicle. This improves the flexibility and adaptability of the wiring of the vehicle charging DC female connector assembly 200, allowing installers to choose the most suitable wire exit method according to the actual situation. This further avoids unnecessary tangling and interference of wires inside the vehicle charging female connector fixing bracket 300 or inside the vehicle, thereby enhancing the reliability and flexibility of the vehicle charging interface structure 10.

[0039] like Figure 2As shown, in one embodiment, the vehicle charging interface structure 10 further includes a dustproof component 400, which includes an elastic connector 410, a dustproof cover 420, and a sealing fastener 430. The vehicle charging female mounting plate 100 also has a cover plate connection through hole 1002. One end of the elastic connector 410 is fixed to the dustproof cover 420, and the other end of the elastic connector 410 passes through the cover plate connection through hole 1002. One end of the sealing fastener 430 is connected to the dustproof cover 420, and the other end of the sealing fastener 430 passes through the charging hole 1001. In this embodiment, when the vehicle charging interface structure 10 is not in use, the dust cover 420 is tightly fitted to the surface of the vehicle charger female mounting plate 100. Simultaneously, the sealing fastener 430 completely covers the charging hole 1001, thus forming an effective dust barrier. This reduces the gap between the dust cover 420 and the area around the charging hole 1001, effectively preventing dust, impurities, and other fine particles from entering the vehicle charger DC female assembly 200 through the charging hole 1001. When the device needs charging, the operator simply moves the dust cover 420, causing it to rotate or shift around the fixing point of the elastic connector 410, exposing the charging hole 1001. The charging terminal of the device can then be inserted into the vehicle charger DC female assembly 200 for charging. After charging is complete, the charging terminal is pulled out of the charging hole 1001, and the operator can move the dust cover 420 again to ensure the sealing fastener 430 tightly covers the charging hole 1001 once more. The coordinated operation of the elastic connector 410, dust cover 420 and sealing fastener 430 improves the dustproof performance of the vehicle charging interface structure 10, effectively extends the service life of the vehicle charging DC female connector assembly 200, and reduces the risk of short circuits, poor contact and other faults caused by dust accumulation.

[0040] like Figure 3 and Figure 2 Figure 2 Figure 3As shown, in one embodiment, the car charger female connector mounting plate 100 includes a bracket fixing post 110 and a mounting cover plate 120. The bracket fixing post 110 is fixed to the end face of the mounting cover plate 120 adjacent to the car charger DC female connector assembly 200. The bracket fixing post 110 has a first threaded through hole 1101, and the car charger female connector fixing bracket 300 has a second threaded through hole 3005. The vehicle charging interface structure 10 also includes threaded fasteners 500, which are respectively inserted into the first threaded through hole 1101 and the second threaded through hole 3005. In this embodiment, because the mounting plate assembly and the fixing assembly are tightly connected, the female connector assembly is firmly fixed inside the mounting plate assembly and the fixing assembly, thereby ensuring that the female connector assembly will not be displaced due to vibration or other external forces during operation, thus ensuring the stability and reliability of the charging interface. Furthermore, traditional solutions typically fix the car charger interface structure directly to a mounting plate by applying glue or welding it directly, making the car charger interface structure non-removable and causing difficulties in disassembly and repair in case of failure. In contrast, the vehicle charging interface structure 10 in this embodiment uses a fixing bracket and fastening screws to lock the various parts together to form an integral component, which is conducive to disassembly and repair, thereby improving the flexibility of the production and maintenance process.

[0041] This application also provides a vehicle power supply, including a vehicle charging interface structure 10 according to any embodiment. In this embodiment, the process of assembling the vehicle charging interface structure 10 requires first installing the vehicle charging DC female connector assembly 200 onto the vehicle charging female connector mounting plate 100, ensuring that the vehicle charging DC female connector assembly 200 corresponds to the charging hole 1001 on the vehicle charging female connector mounting plate 100. Then, the vehicle charging female connector fixing bracket 300 is sleeved on the vehicle charging DC female connector assembly 200, and the vehicle charging DC female connector assembly 200 is connected and fixed to the vehicle charging female connector mounting plate 100 by fasteners, so that the vehicle charging female connector mounting plate 100, the vehicle charging DC female connector assembly 200, and the vehicle charging female connector fixing bracket 300 form an integral structure, thereby facilitating the fixing and disassembly of the vehicle charging interface structure 10. When the device needs charging, its charging end is inserted into the DC charging connector 200 through the charging port 1001, establishing an electrical connection. This allows the energy from the storage battery to be transferred to the device via the DC charging connector 200 and its connecting wires, thus enabling the vehicle charging interface structure 10 to perform its charging function. Furthermore, during operation, the DC charging connector 200 generates heat. To maintain its operating temperature within a safe range, the heat dissipation holes 3001 effectively dissipate the heat to the external environment, preventing overheating and potential injury to operators. Additionally, the connecting wires of the DC charging connector 200 pass through the wire holes in the mounting bracket 300, preventing the wires from becoming tangled within the bracket and allowing for multiple cable exit methods, thereby improving the applicability of the vehicle charging interface structure 10.

[0042] Compared with the prior art, this disclosure has at least the following advantages:

[0043] 1. The aforementioned vehicle charging interface structure 10 integrates the vehicle charging DC female connector assembly 200, the vehicle charging female connector mounting plate 100, and the vehicle charging female connector fixing bracket 300 into a single structure, which improves the assembly and disassembly efficiency and stability of the vehicle charging interface structure 10. Furthermore, the female connector heat dissipation holes 3001 provided in the vehicle charging female connector fixing bracket 300 effectively enhance the heat dissipation efficiency of the vehicle charging DC female connector assembly 200 and reduce the risk of operator injury due to overheating.

[0044] 2. In addition, since the vehicle charger female connector fixing bracket 300 has a female connector wire hole and the connecting wire of the vehicle charger DC female connector assembly 200 passes through the female connector wire hole, the vehicle charging interface structure 10 can be compatible with multiple wiring methods. This allows the connecting wire of the vehicle charger DC female connector assembly 200 to be applicable to the wiring connection methods of different battery modules, thereby improving the adaptability of the vehicle charging interface structure 10.

[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
