It should be understood that the embodiments described are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0050] This application provides a housing structure 100 of a new automobile charging and distribution system. Figure 1 This is an exploded schematic diagram of a housing structure suitable for a new automobile charging and distribution system provided in an embodiment of the present application; Figure 2A schematic diagram of the structure of the housing of the housing structure for a new type of charging and distribution system for an automobile provided in an embodiment of the present application is shown as follows: Figure 1 and Figure 2 As shown, the housing structure of the novel automotive charging and distribution system includes an upper cover 10 and an outer shell 20. The outer shell 20 defines a receiving cavity 201. The upper cover 10 is mounted on the outer shell 20 and seals the receiving cavity 201. A cooling circulation structure 30 is provided within the outer shell 20. The cooling circulation structure 30 divides the receiving cavity 201 into multiple module installation areas 302 for accommodating power distribution modules.

[0051] In the present application, the cooling circulation structure 30 is formed by protruding from the bottom wall of the shell 20 toward the upper cover 10, and a coolant flow channel is provided in the cooling circulation structure 30; at least part of the power distribution function module is thermally connected to the cooling circulation structure 30.

[0052] In the above technical solution, the cooling circulation structure 30 is disposed within the housing 20, dividing the receiving cavity 201 into multiple module mounting areas 302. The power distribution function modules are fixed within the module mounting areas 302, and the power distribution function modules are connected to the cooling circulation structure 30 for heat conduction. This three-dimensional and simple cooling circulation structure 30 effectively improves the heat dissipation efficiency of the modules within the housing, prevents the modules from overloading due to high temperatures, and helps to extend the service life of the charging and distribution system while reducing production and maintenance costs.

[0053] Please continue reading Figure 1 The upper cover 10 is disposed on the outer shell 20 and connected to the outer shell 20 to form a receiving cavity 201. Specifically, the upper cover 10 has a plurality of fixing holes, and the upper cover 10 and the outer shell 20 can be locked by fixing screws and the receiving cavity 201 can be sealed.

[0054] In the above technical solution, the upper cover 10 and the outer shell 20 are locked together to form a receiving cavity 201. This structure effectively protects the power distribution function module and avoids problems such as displacement, falling off, leakage and short circuit of the power distribution function module.

[0055] Please continue reading Figure 1 、 Figure 2 and Figure 3 The housing 20 is a rectangular shell having a receiving cavity 201. The housing 20 can be processed using a metal die-casting process. The housing 20 can be made of an alloy, such as an aluminum alloy or a titanium alloy. These materials provide the housing 20 with a strong structural strength, thereby improving the durability of the housing 20.

[0056] In the above technical solution, the shell 20 has a simple structure, a mature processing technology, and the material used is not easy to rust and has a certain corrosion resistance.

[0057] The outer shell 20 is provided with a cooling circulation structure 30. The external structure of the cooling circulation structure 30 is a rib extending from the bottom wall of the outer shell 20 toward the upper cover 10 to form a rib parallel to the side wall of the outer shell 20. The cooling circulation structure 30 divides the housing cavity 201 of the outer shell 20 into a plurality of module installation areas 302. The module installation area 302 is composed of a plurality of square rib structures and is used to accommodate the power distribution function module. The cooling circulation structure 30 can be integrally formed with the bottom wall of the outer shell 20 through a metal die-casting process and the outer shell 20. In other embodiments, the cooling circulation structure 30 can also be independently formed and installed in the outer shell 20. In the above technical solution, the cooling circulation structure 30 is in the form of a three-dimensional frame, which is conducive to increasing the contact area with the module and improving the heat dissipation efficiency.

[0058] For further information, please refer to Figure 2 and Figure 4 The cooling circulation structure 30 includes a first cooling water channel 304 and a second cooling water channel 306. Two first cooling water channels 304 are parallel to the sidewalls of the outer shell 20, and a second cooling water channel 306 connects the two first cooling water channels 304. The second cooling water channel 306 is parallel to the end wall of the outer shell 20. The first cooling water channels 304 and the second cooling water channels 306 protrude from the bottom wall of the outer shell 20, and the first cooling water channels 304 and the second cooling water channels 306 have interconnecting coolant flow channels. The provision of the first cooling water channels 304 divides the receiving cavity 201 into at least three module installation areas 302 along the sidewalls of the outer shell 20. The provision of the second cooling water channels 306 further divides the module installation area 302 enclosed by the two first cooling water channels 304, thereby dividing the module installation area 302 into smaller units. This allows for the efficient installation of power distribution modules of varying sizes and improves heat dissipation efficiency. Specifically, the metal die-casting process can be used for processing, and the housing 20 can be die-casted at one time.

[0059] In the above technical solution, the multiple module installation areas 302 are conducive to accommodating multiple modules, thereby improving the heat dissipation efficiency and reducing the risk of module aging and failure due to high temperature overload.

[0060] Furthermore, after the bottom plate 312 is fixed to the bottom of the shell 20, a sealed coolant flow channel is formed inside the cooling circulation structure 30. In order to keep the coolant in the coolant flow channel in a circulating flow channel and improve the heat dissipation efficiency, a liquid outlet pipe 308 and a liquid inlet pipe 310 are opened on the end wall of one side of the shell 20 of the present application. The coolant in the coolant flow channel flows through the first cooling water channel 304 and the second cooling water channel 306 through the liquid inlet pipe 310 and flows out to the outside of the shell structure through the liquid outlet pipe 308, realizing the circulating cooling treatment of the coolant. The power distribution function module installed in the module installation area 302 and the cooling circulation structure 30 exchange heat through mutual heat conduction cooling and heat exchange.

[0061] In the above technical solution, the coolant circulating in the cooling circulation structure 30 transfers the heat of the module to the coolant, and then circulates the heat of the coolant to the vehicle cooling system, thereby accelerating the heat dissipation efficiency of the module. Figure 3 As shown, the bottom wall of the shell 20 is provided with a plurality of fixing parts 202 arranged circumferentially around the accommodating cavity 201. The fixing parts 202 protrude from the bottom of the shell 20. The shape of the fixing parts 202 can adopt a regular shape or an irregular shape. The fixing parts 202 are provided with mounting holes and can be installed with fixing devices, such as fixing bolts, fixing screws and other structures. After the fixing devices are installed, the fixing parts 202 are used to install and fix the power distribution function module. The fixing parts 202 can be die-casted at one time with the shell 20 using a metal die-casting process.

[0062] In the above technical solution, the structure of the fixing member 202 is conducive to quickly fixing the power distribution function module, and can adapt to the size change of the module within a certain range, and has a certain compatibility.

[0063] In some embodiments, the fixing member 202 can be a fixed stud. The fixed stud has a conical shape and an internal mounting screw hole. The inner hole surface can be threaded. The fixed stud is used to install a bolt to secure the power distribution function module. After the power distribution function module is secured, it can be glued to strengthen the fixing strength of the power distribution function module. The fixed stud can be die-casted with the housing 20 using a metal die-casting process to form an integral structure.

[0064] In the above technical solution, the fixing member 202 is a tapered stud. The tapered structure facilitates demolding during the metal die-casting process. The dual fixation of multiple fixing studs and the glue potting process ensures that the module will not shift after being fixed, avoiding circuit problems or digital signal transmission issues caused by module movement after being fixed.

[0065] In order to facilitate the installation and fixation of the power distribution functional module and reduce the movement or offset of the power distribution functional module during the movement of the automobile, the bottom wall of the shell 20 is also provided with a plurality of positioning ribs 204. The positioning ribs 204 are formed by protrusions extending toward the upper cover 10. The cross-sectional shape of the positioning ribs 204 is square, semicircular or irregular. The two ends of the positioning ribs 204 are respectively connected to the side walls of the shell 20 and the side walls of the first cooling water channel 304. The connection method can be a vertical connection, thereby separating the module installation area 302 into the functional module installation area 302. The positioning ribs 204 can be die-casted with the shell 20 at one time using a metal die-casting process.

[0066] In the above technical solution, the positioning rib 204 is in the form of a rib structure, which has the advantages of simple processing technology and low cost.

[0067] In order to facilitate the installation and fixation of the entire shell structure on the car frame, Figure 2 and Figure 3 As shown, four brackets 208 are provided on the end walls of the housing 20 for mounting and securing the housing structure of the new automotive charging and distribution system. Brackets 208 are rectangular in shape and have mounting holes. Brackets 208 can be die-casted with the housing 20 in one piece using a metal die-casting process. Triangular reinforcing ribs 2082 can be provided at the junction of brackets 208 and the housing 20 to strengthen the connection between the housing 20 and brackets 208.

[0068] In the above technical solution, the four brackets 208 and the triangular reinforcement ribs 2082 can effectively fix the shell structure on the vehicle body structure after the bracket fixing bolts are installed, reducing the risk of the shell structure loosening and falling off on the vehicle body structure.

[0069] Specifically, such as Figure 1 、 Figure 3 and Figure 4 As shown, two grounding terminals 210 are provided on the side and end walls of the housing 20 to ground the housing structure of the new vehicle charging and distribution system to the vehicle body. The grounding terminals 210 have a square, semicircular, or irregular cross-sectional shape and are provided with through-holes. They extend outward perpendicularly from the side and end walls of the housing 20. A primary boss 2102 may be provided at the junction of the grounding terminals 210 and the housing 20 to strengthen the connection between the two terminals. The grounding terminals 210 can be die-cast together with the housing 20 using a metal die-casting process.

[0070] In the above technical solution, the grounding terminal 210 provided on the housing 20 has a simple structure and is integrally formed with the housing 20 , and has the characteristic of high connection strength.

[0071] Specifically, such as Figure 3 and Figure 4 As shown, the sidewall of the housing 20 is provided with a vent valve interface 212 for exhausting gases from the housing of the new automotive charging and distribution system. The vent valve interface 212 is cylindrical and has a through-hole. Three circularly distributed arcuate ribs 2122 are located on the outside of the vent valve interface 212. These arcuate ribs 2122 strengthen the connection between the vent valve and the housing 20. The vent valve interface 212 and the arcuate ribs 2122 extend perpendicularly outward from the sidewall of the housing 20 to form the valve body structure. The intersection of the arcuate ribs 2122 and the vent valve interface 212 with the housing 20 can be chamfered to prevent stress concentration caused by right angles at the junction, which could reduce connection strength. The vent valve interface 212 and the arcuate ribs 2122 can be die-cast together with the housing 20 using a metal die-casting process.

[0072] In the above technical solution, the shape and structure of the ventilation valve interface 212 can effectively ensure the stability of the connection with the ventilation valve.

[0073] Specifically, such as Figure 3 and Figure 4 As shown, an input / output interface 214 is provided on the side wall of the housing 20 for inputting and outputting electrical energy and digital signals for the vehicle's novel charging and distribution system. The input / output interface 214 has an elliptical cross-section and is provided with a through-hole. The input / output interface 214 extends outward perpendicularly from the side wall of the housing 20. The input / output interface 214 can be formed simultaneously with the housing 20 using a metal die-casting process.

[0074] In the above technical solution, the input / output interface 214 has a firm structure and a large port area, and can effectively fix the input / output terminals to prevent them from falling off.

[0075] During the installation of the charging and distribution function module, the module is positioned using the internal positioning ribs 204 of the housing, and then fixed and installed with bolts, supplemented by glue injection to strengthen the fixed module, thereby reducing the constraints of the internal structure of the housing on the components, and enabling the housing to adapt to different models of charging and distribution function module components. At the same time, a coolant flow channel is provided inside the ribs of the housing module installation area 302, which increases the contact area between the charging and distribution function module and the cooling water channel, facilitating rapid heat dissipation. The housing structure of the new automotive charging and distribution system provided in this application can improve heat dissipation efficiency, facilitate the installation of compatible different functional modules, and reduce the overall volume and weight of the housing.

[0076] The present application also provides an automobile, which includes the shell structure of the above-mentioned new automobile charging and distribution system. Installing the above-mentioned shell structure in an automobile, especially an electric car, is conducive to heat management of the charging and distribution system, improving heat dissipation efficiency, and at the same time maximizing the reduction of the weight and volume of the shell structure.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
