Description

Technical Field

[0001] This application relates to the field of vehicle parts, specifically an on-board charger and a vehicle. Background Technology

[0002] As a core component of new energy vehicles, the on-board charger's installation and fixing structure needs to be adapted to the installation space of different vehicle models. Once the casing of an on-board charger is developed, the fixing method is often difficult to adjust, making it difficult for the same on-board charger to be universally applicable across different vehicle models and projects. Developing a separate casing mold for each vehicle model would not only significantly increase costs but also extend the development cycle, impacting project efficiency. Achieving flexible adaptability of the on-board charger structure while controlling costs and timelines has become a significant challenge for developers in the industry. Summary of the Invention

[0003] This application provides an on-board charger and a vehicle, enabling users to adapt an on-board charger housing to different vehicle installation requirements.

[0004] The technical solution of this application is as follows: An on-board charger includes: a main housing with a split design and a mounting component; The mounting component is installed on the main housing, and the mounting component is provided with mounting holes for vehicle body connection.

[0005] Preferably, the main housing has a mating surface that matches the mounting component, and the mating surface is flush with or protrudes from the main housing.

[0006] Preferably, the main housing and the mounting component are fixed by welding.

[0007] Preferably, the main housing and the mounting component are fixed by screws.

[0008] This application also provides a vehicle, including a body connecting bracket and the above-mentioned on-board charger, wherein the body connecting bracket is connected to the mounting holes on the mounting component by bolts.

[0009] The beneficial effects of this application are as follows: Based on the different installation requirements of the on-board charger, a suitable mounting component is selected and installed on the on-board charger, and then connected to the vehicle body through the mounting component; thus, the main housing of the on-board charger can meet the needs of multiple projects, reducing the development cost of the main housing.

[0010] Figure 1 This is an assembly diagram of the main housing and mounting components of the on-board charger in an embodiment of this application; Figure 2 This is a schematic diagram of the assembly of the main housing and mounting components of the on-board charger in this embodiment of the application. Detailed Implementation

[0011] Reference Figure 1 and Figure 2 This application provides an on-board charger, including: a main housing 1 with a split design and a mounting component 2; The mounting component 2 is mounted on the main housing 1, and the mounting component 2 is provided with mounting holes 21 for vehicle body connection.

[0012] In this embodiment, the on-board charger is divided into two independent parts. The main housing 1, as an immutable universal structure, is used to encapsulate and protect the core power electronic components, and its design is determined by the inherent physical requirements of the internal electronic components, such as electrical performance, magnetic properties, and thermal performance.

[0013] Mounting component 2, as a variable adaptable structure, is designed based on external, variable vehicle installation environment parameters (such as the position of body panel studs and the spatial contour of the body panel). In this embodiment, mounting component 2 can be configured as any of the following structural forms: mounting leg, mounting angle, and mounting bracket. The shape, size, and thickness of mounting component 2 can be flexibly adjusted according to actual product requirements. For example, the shape of mounting component 2 can be set to... Figure 1 The square shape in the middle.

[0014] By designing the main housing 1 and the mounting component 2 as separate units, the compatibility problem caused by differences in vehicle models in fixed structures is successfully solved. This solution allows the main housing 1 to maintain structural uniformity as a universal functional platform, while the mounting component 2 serves as a customizable interface, achieving mechanical connection with different vehicle body types through its mounting holes 21. This design decouples the on-board charger from the mounting interface, allowing for rapid adaptation to new projects with only the development of a specific mounting component 2 at extremely low cost and time. This effectively avoids the high cost and long development cycle of repeatedly developing a complete housing for different vehicle models while ensuring the advantages of platformization and standardization, achieving a balance between universality and specialization.

[0015] In this embodiment, the main housing 1 and the mounting component 2 can be fixed together by means of screwing or welding. By providing both welding and screwing as fixing methods, the main housing 1 and the mounting component 2 can be designed to select the optimal fixing method according to the needs of different vehicle models, thereby further expanding the applicability of this platform-based solution while ensuring the fundamental reliability of the connection.

[0016] In this embodiment of the application, when the main housing 1 and the mounting part 2 are fixed by welding (e.g., laser welding), refer to Figure 1The main housing 1 has a mating surface 11 that matches the mounting component 2. Since the mating surface 11 is part of the outer surface of the main housing 1, the specific position of the mating surface 11 can be flexibly selected according to actual needs. That is to say, the selection position of the mating surface 11 is not limited to the position specified in the appendix of this application. Figure 1 At the corners and edges. After selecting the specific location of the mating surface 11, weld the mounting part 2 at the corresponding location; for example... Figure 1 As shown, multiple welds 3 are formed at the mating point between the main housing 1 and the mounting component 2.

[0017] In this embodiment, the mating surface 11 is flush with or protrudes from the main housing 1. When the mating surface 11 is flush with the main housing 1, it achieves a smooth fit with the vehicle body sheet metal, forming a stable surface contact and avoiding stress concentration caused by point or line contact. When the mating surface 11 protrudes from the main housing 1, it actively constructs a cantilever or support platform, allowing installation forces (such as bolt preload and vehicle vibration loads) to be directly and efficiently transmitted to the rigid body of the main housing 1 through this reinforced structure. Regardless of whether the mating surface 11 is flush or protruding, it serves as a standardized part, clearly separating the mechanical connection function of the mounting component 2 from the core functions of the main housing 1, such as sealing, heat dissipation, and electromagnetic shielding. This design allows the mounting component 2 to be independently designed and optimized based on a defined benchmark without altering the internal layout and wall thickness of the main housing 1, truly achieving plug-and-play functionality for the mechanical interface module.

[0018] Those skilled in the art can, depending on the requirements, design the mating surface 11 flush with the vehicle body where there is ample installation space to help achieve a compact layout; or design the mating surface 11 to protrude from the vehicle body where it is necessary to avoid surrounding pipelines or sheet metal structures to actively create installation space, ensure the operability of bolt tools and reliable connection with the vehicle body, which provides key structural freedom to adapt to the ever-changing vehicle layout requirements.

[0019] When the main housing 1 and the mounting part 2 are fixed by screws, a threaded hole is provided on the main housing 1. The specific location of the threaded hole can be obtained by machining at a selected position according to actual needs after the main housing 1 is manufactured. Since the threaded hole is machined on the main housing 1 later, the arrangement of the threaded hole can be flexibly selected according to the vehicle model requirements. After the threaded hole is formed, a screw or bolt passes through the mounting part 2 and forms a stable connection with the main housing 1.

[0020] For the mounting part 2 in this application embodiment, the mounting holes 21 arranged thereon can be flexibly adjusted according to the vehicle body assembly requirements; in some cases, different sizes or shapes of mounting parts 2 can also be replaced to match the requirements of different vehicle models.

[0021] This application embodiment also provides a vehicle, including a body connecting bracket and the above-mentioned on-board charger, wherein the body connecting bracket is connected to the mounting holes 21 on the mounting member 2 by bolts.

[0022] In the embodiments of this application, the vehicle may be, but is not limited to, a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), or a new energy vehicle.

[0023] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this application still fall within the scope of this application.
