Technical Field

[0001] This utility model relates to the field of automotive electronics technology, and in particular to a redundant power supply interface component for vehicle display backlight modules. Background Technology

[0002] With the increasing intelligence of automobiles, in-vehicle display devices have become an indispensable part of modern vehicles. As one of the core components of display devices, the stability and reliability of the power supply system for the in-vehicle display backlight module directly affects the performance of the entire display device. Especially in the face of complex in-vehicle environments, such as high temperatures, vibrations, and limited space, ensuring a stable and efficient power supply for the backlight module has become a significant challenge for designers. Traditional power supply systems often fall short in meeting these challenges, necessitating a more efficient and flexible solution to satisfy the growing demand.

[0003] Currently, the integration between redundant power supply components and the main power supply system is insufficient, which significantly limits the layout flexibility of backlight modules in automotive display devices. Due to the lack of effective modular design and rapid assembly mechanisms, existing devices struggle to meet the diverse installation requirements of display devices in the complex in-vehicle environment. Furthermore, traditional power supply interfaces are mostly fixed or semi-fixed, increasing the difficulty of on-site installation and maintenance. Moreover, they are prone to loosening or poor contact when exposed to vibrations and other adverse factors during vehicle operation, affecting power supply stability. These problems mean that existing power supply solutions cannot fully meet the development needs of automotive display devices.

[0004] Therefore, there is an urgent need for a modular, rapid-assembly redundant power supply interface component for automotive display backlight modules. Utility Model Content

[0006] The technical solution of this utility model is as follows: This utility model provides a redundant power supply interface assembly for a vehicle display backlight module, including a redundant power supply interface, a slide-in electrical connector, and a plug-in power supply module. The slide-in electrical connector is movably mounted on the redundant power supply interface. Several plug-in power supply modules are movably snapped onto the slide-in electrical connector. The plug-in power supply modules are symmetrically provided with locking blocks and slots. Adjacent plug-in power supply modules are movably snapped together. The plug-in power supply modules are provided with several sockets.

[0007] Preferably, it also includes a fixing sleeve, a connecting tube, and a vent tube. The fixing sleeve is symmetrically installed on one side of the slide-in electrical connector, and the connecting tube is installed on the fixing sleeve. The vent tube is symmetrically installed on the redundant power supply interface, and the vent tubes are all connected to the connecting tube.

[0008] Preferably, it also includes a fixing block, a guide plate, and a baffle. The fixing block is symmetrically installed on one side of the redundant power supply interface, the guide plate is rotatably connected to the fixing block, and the baffle is connected to the guide plate.

[0009] Preferably, it also includes a guide, with guides installed on the same plug-in power supply module's sockets.

[0010] Preferably, the plug-in power supply module has several grooves symmetrically arranged on it.

[0011] Preferably, the redundant power supply interface has gripping grooves on both sides.

[0012] The beneficial effects of this utility model are:

[0013] This invention achieves modular, rapid assembly and flexible layout by using a slide-in electrical connector to engage with a redundant power supply interface and by allowing adjacent plug-in power supply modules to be connected in a movable snap-fit ​​manner.

[0014] This invention forms a heat dissipation air duct by connecting the connecting pipe to the ventilation pipes on both sides, and drives the guide plate to rotate and limit the position of the baffle, so as to realize airflow cooling and prevent the connection from loosening, thereby achieving efficient heat dissipation and stable and reliable operation.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1: Redundant power supply interface assembly for vehicle display backlight module, such as Figures 1-3 As shown, the system includes a redundant power supply interface 1, a slide-in electrical connector 2, and a plug-in power supply module 3. The redundant power supply interface 1 serves as the core power input for the entire system. Its front side is connected to the slide-in electrical connector 2 via a movable mounting method. The two are connected by a precision guide rail structure, enabling a quick, stable, and repeatedly detachable electrical connection, facilitating on-site installation, maintenance, and replacement. The redundant power supply interface 1 has symmetrically designed grip grooves on both sides. These grooves are ergonomically designed and have an anti-slip surface, allowing operators to grip the interface securely in confined spaces or while wearing gloves, effectively improving the safety and convenience of the insertion and removal process. The slide-in electrical connector 2... Up to eight plug-in power supply modules 3 can be flexibly connected to the upper panel, enabling flexible expansion of power supply capacity. Each plug-in power supply module 3 has symmetrically distributed card blocks and slot structures, which can not only reliably connect with the slide-in electrical connector 2, but also be assembled in series with adjacent modules through a card-connection method to form a stable modular power supply array with good vibration resistance and anti-loosening performance. The plug-in power supply module 3 integrates nine standardized sockets 4, the layout of which can be modified to support multiple output configurations. Power cables or connectors can be flexibly connected according to the electrical requirements of different backlight modules, making it widely adaptable to various vehicle display power supply scenarios.

[0024] When configuring a power supply system for an automotive display backlight module, firstly, slide the slide-in electrical connector 2 smoothly along the guide rail of the redundant power supply interface 1 to achieve a stable and reliable electrical connection. The slide-in design is easy to operate, precise in positioning, supports quick assembly and disassembly, and facilitates maintenance and replacement. Subsequently, according to the actual power supply requirements and installation space, select the required number of plug-in power supply modules 3. Through the symmetrically arranged locking blocks and slots on them, the modules are sequentially locked onto the slide-in electrical connector 2. Adjacent modules can also be connected in series laterally through locking blocks and slots. The structure is stable and prevents loosening, forming a modular power supply array. Each plug-in power supply module 3 has multiple sockets 4. The sockets 4 can be flexibly configured into various arrangements according to the power interface layout of different backlight modules, adapting to the power supply requirements of various display modules. This not only improves the system's scalability and compatibility but also greatly enhances the application's flexibility and maintainability, making it suitable for complex and ever-changing automotive electronic environments.

[0025] Example 2: Based on Example 1, such as Figures 4-6 As shown, it also includes a fixing sleeve 5, a connecting pipe 6, a vent pipe 7, a fixing block 8, a guide plate 9, a baffle 10, and a guide component 11. Two fixing sleeves 5 are arranged vertically on the right side of the slide-in electrical connector 2, and the connecting pipe 6 is connected to both fixing sleeves 5. Two vent pipes 7 are arranged on the left side of the redundant power supply interface 1, and the two vent pipes 7 are connected to the connecting pipe 6, forming an efficient heat dissipation channel and constructing a complete airflow path to ensure continuous cooling effect inside the system. Fixing blocks 8 are arranged vertically on the right front side of the redundant power supply interface 1, and guide plates 9 are rotatably connected to the fixing blocks 8. Baffles 10 are connected to the guide plates 9. When the slide-in electrical connector 2 is correctly inserted, the guide plate 9 can be used to rotate the baffle 10 into position, thereby locking the slide-in electrical connector 2 to prevent it from loosening due to vibration or external force, which greatly enhances the connection stability of the system. Each plug-in power supply module 3 has nine sockets 4 connected to a guide 11. The guide 11 has a precise guiding function to ensure that the external power plug can be accurately inserted into the corresponding socket, avoiding electrical faults or damage caused by misinsertion. The plug-in power supply module 3 has two grooves 12 on the top and bottom, providing better gripping points for easy disassembly and maintenance.

[0026] When it is necessary to perform heat dissipation and structural stabilization operations on the power supply system of the vehicle display backlight module, the connecting pipe 6 is connected to the two vent pipes 7 on both sides of the redundant power supply interface 1 to form a through heat dissipation air duct. The external cooling airflow can enter from one end of the vent pipe 7, pass through the connecting pipe 6 and then exit from the other end of the vent pipe 7, effectively cooling the surrounding area of ​​the slide-in electrical connector 2 and the plug-in power supply module 3, achieving continuous heat dissipation and significantly improving the operational stability under high temperature environment. In addition, the guide plate 9 is moved along the fixed block 8 to drive the baffle 10 to rotate synchronously, thereby limiting and locking the insertion port of the slide-in electrical connector 2 to prevent loosening due to vibration or external force, and improving the connection reliability.

[0027] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
