Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an assembled installation device for an electric vehicle EVCC communication controller. Background Art

[0002] Electric vehicles, with their advantages of zero emissions, low noise, and high energy efficiency, are considered a key direction for future automotive industry development. To promote widespread adoption of electric vehicles, a comprehensive charging infrastructure is crucial. Electric vehicle charging control technology plays a central role in this process, particularly the electric vehicle charging controller (EVCC). As a key component for communication between the vehicle and the charging equipment, the EVCC assumes important responsibilities such as controlling the charging process, transmitting charging parameters, and monitoring the charging status. To effectively perform these functions, the EVCC must be connected to other systems within the vehicle via multiple wiring harnesses.

[0003] However, the compact arrangement of various structures and components within the limited space of an electric vehicle poses a challenge to the installation location of the EVCC. Currently, the EVCC is typically placed between two other components, with the majority of wiring harnesses extending from the rear. Those that need to be routed forward must pass through the side or bottom of the controller. This wiring method presents several significant issues: First, the connections are not secure enough and can easily become loose during driving, especially when encountering large bumps; second, the wiring harnesses are arranged disorganized and prone to mutual interference, which not only violates the requirements of a compact design but also poses safety risks. Summary of the Invention

[0004] To address the aforementioned technical issues, the present invention provides an assembled mounting device for an electric vehicle (EVCC) communication controller. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is provided below. This summary is not intended to be a comprehensive review, identify key or important components, or delineate the scope of protection for these embodiments. Its sole purpose is to present some concepts in a simplified form, serving as a prelude to the detailed description that follows.

[0005] The utility model adopts the following technical solutions:

[0009] The top end of the mounting bracket is bent and extended inward to form the first supporting plate perpendicular to the mounting bracket, and screw holes for connecting with the bottom substrate by bolts are provided on the first supporting plate.

[0010] The bottom end of the mounting bracket is bent and extended outward to form the second bearing plate perpendicular to the mounting bracket, and screw holes for connecting with the frame structure are provided on the second bearing plate.

[0017] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0018] like Figure 1-2 As shown, in some illustrative embodiments, an assembled installation device for an electric vehicle EVCC communication controller is provided, which improves the stability and reliability of the charging management system by optimizing the installation method and wiring harness management of the controller. The device mainly includes two parts: a controller housing and an assembly structure.

[0019] The controller housing houses circuit boards and other components, constructed from high-strength, corrosion-resistant materials such as aluminum alloy or reinforced plastic. This protects the internal circuitry from the external environment while reducing overall weight. The controller housing features multiple standardized interfaces for easy connection to other vehicle systems, with a number of spare interfaces reserved. An assembly structure connected to the controller housing facilitates in-vehicle assembly and wiring harness guidance for the communication controller, ensuring it remains positioned or loosened while the vehicle is in motion. This ensures that the wiring harness leading from the controller is routed in an orderly manner to minimize interference.

[0020] The controller housing includes: a bottom substrate 1, an upper shell 2 and a sealing rubber ring 3.

[0021] The bottom substrate 1 is a flat plate structure that can serve as a basic platform to carry and fix the electronic components inside the controller. The upper surface of the bottom substrate 1 is provided with a limiting enclosure 101 for accommodating the PCB board. The limiting enclosure 101 is strip-shaped and encloses an independent space in which the PCB board is fixed by screws. The limiting enclosure 101 can ensure that the PCB board can be accurately positioned during installation, while preventing displacement during transportation and use, and has a certain impact resistance effect. The buckle shell 2 matches the bottom substrate 1 and is tightly combined with the bottom substrate 1 by buckling or screw fixing to form a closed shell.

[0022] A rubber strip slot 102 is provided on the inner side of the top of the limiting enclosure 101, and a pressing ridge 201 is provided at the position corresponding to the rubber strip slot 102 on the upper buckle shell 2. The function of the pressing ridge 201 is to cooperate with the rubber strip slot 102 during assembly of the shell to achieve the pressing of the sealing rubber ring 3. The sealing rubber ring 3 is provided in the rubber strip slot 102, that is, at the junction of the bottom substrate 1 and the upper buckle shell 2. After the bottom substrate 1 and the upper buckle shell 2 are connected as one, the pressing ridge 201 is embedded in the rubber strip slot 102, and the pressing ridge 201 is pressed on the sealing rubber ring 3, so that the sealing rubber ring 3 can be tightly filled in the gap between the two shells, thereby achieving a sealing effect. Through the design of the pressing ridge 201 and the rubber strip slot 102, the sealing rubber ring 3 can be firmly pressed at the junction of the shell, effectively preventing moisture, dust and other foreign matter from entering the interior of the shell, and protecting the internal electronic components. Moreover, the above design makes the controller housing assembly process simpler and more efficient. At the same time, the cooperation between the pressed protrusion 201 and the rubber strip slot 102 increases the stability of the controller housing connection and reduces the risk of housing separation due to vibration or impact.

[0023] The bottom of the buckle housing 2 is equipped with a horizontal pressure plate 202 extending outward. This plate 202 provides an additional fixing point, enhancing the overall stability of the housing. A notch is provided in the plate 202, and four mounting holes 103 are provided in the bottom base plate 1 corresponding to the notch to facilitate assembly of the controller into the vehicle interior.

[0024] The assembly structure includes: a wire harness clamp 4, two groups of mounting brackets 5 and positioning coils 6 arranged between each group of mounting brackets 5. Each group has two mounting brackets 5. Therefore, there are a total of four mounting brackets 5 and two positioning coils 6, and the two mounting brackets 5 in each group are located on both sides of the controller housing.

[0025] The wiring harness clamp 4 is located at the rear of the controller housing, specifically behind the base plate 1. Specifically, it comprises two clamping plates 401 and a rubber pad 402 positioned on the facing sides of the two clamping plates 401. The rubber pad 402 has several arcuate grooves formed in it, and the two clamping plates 401 are connected by bolts. The rubber pad 402 protects the wiring harness from damage during clamping, and the arcuate grooves accommodate wiring harnesses of varying sizes and shapes. The two clamping plates 401 are bolted together to ensure stable and convenient clamping.

[0026] The wire harness leading out of the rear interface of the controller housing is clamped and secured with a wire harness clamp 4. When the wire harness only needs to be routed to the rear of the controller, it can be directly secured with the wire harness clamp 4. When the wire harness needs to pass through the bottom of the controller and be routed to the front of the controller, it is first secured with the wire harness clamp 4, then passed through the positioning coil 6 at the bottom of the controller, and finally routed to the front.

[0027] A first support plate 7 is disposed on the inner side of the top end of the mounting bracket 5 (the inner side refers to the side facing the controller housing). This support plate 7 is used to connect to the base substrate 1. Specifically, the top end of the mounting bracket 5 bends inward to form the first support plate 7, which is perpendicular to the mounting bracket 5. The first support plate 7 is provided with screw holes for bolting to the base substrate 1. The screw holes in the first support plate 7 allow the mounting bracket 5 to be securely connected to the base substrate 1 via bolts, ensuring the stability of the entire assembly structure within the controller housing.

[0028] A second support plate 8 is disposed outside the bottom end of the mounting bracket 5. This support plate 8 is used to connect to other vehicle structures. Specifically, the bottom end of the mounting bracket 5 bends and extends outward to form a second support plate 8 perpendicular to the mounting bracket 5. This second support plate 8 is provided with screw holes for bolting to the vehicle frame. These screw holes allow the mounting bracket 5 to be securely connected to the vehicle frame via bolts, ensuring the stability of the entire assembly within the vehicle.

[0029] A fixing plate 9 is also provided at the bottom end of the mounting bracket 5, and the end of the positioning coil 6 is connected to the fixing plate 9 via a cantilever beam 10. The present application appropriately elevates the position of the controller through two sets of mounting brackets 5, creating a reasonable gap between the controller and the structure below without affecting the structure above it. The present application adaptively sets the positioning coil 6 in the gap, and at the same time combines it with the wiring harness clamp 4 to achieve the assembly of the controller and the front and rear guidance of the wiring harness, ensuring that the wiring harness is neatly laid along the predetermined path, reducing interference with each other and with other structures, and without taking up additional space in the vehicle.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
