Description

Technical Field

[0001] This utility model relates to the field of vehicle instrument panel technology, and in particular to an LVDS interface connection structure for vehicle instrument panel. Background Technology

[0002] The vehicle infotainment system is the core human-machine interaction and information display terminal in the car cockpit. Its core function is to present key information such as vehicle operating status, driving assistance data, and multimedia information to the driver in an intuitive and clear manner, while taking into account both the convenience of interaction and driving safety. A vehicle infotainment system LVDS interface connection structure refers to a dedicated connection system based on the LVDS technology standard between the vehicle's main unit and the instrument display screen in the car cockpit, used for the stable transmission of image data and control signals.

[0003] Traditional LVDS interface connection structures for vehicle instrument panels often employ a single snap-fit ​​or plug-in connection structure during use. This structure relies solely on a single snap-fit ​​or frictional force to fix the plug and the housing, resulting in insufficient connection stability and difficulty in resisting vehicle vibration interference. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle infotainment system LVDS interface connection structure to address the shortcomings of existing vehicle infotainment system LVDS interface connection structures in terms of stability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vehicle instrument panel LVDS interface connection structure, including a connection shell;

[0006] A plug is installed inside the connecting shell. A first wire is fixed to one end of the plug, and a second wire is fixed to one end of the connecting shell. A connecting structure is fixed to the outside of the plug. The connecting structure includes fixing blocks fixed to both sides of one end of the plug. A movable groove is provided inside the fixing block. A locking block is fixed to one side of the fixing block. Locking slots are provided on both sides inside the connecting shell. A fixing plate is fixed to the outside of the first wire at one end of the plug. Locking rods are fixed to both sides at the other end of the plug. Protrusions are fixed to the other two sides inside the connecting shell.

[0007] The connecting shell has a protective structure inside.

[0008] Preferably, the plug fits into the interior of the connecting shell, and the output end of the plug is electrically connected to the input end of the connecting shell.

[0009] Preferably, the fixing blocks are symmetrically distributed on both sides of one end of the plug, the two sides of the locking block are set with bevels, and the locking block and the connecting shell form a locking structure through the locking groove.

[0010] With the above structure, the inclined design on both sides of the locking block can guide the locking block to smoothly squeeze the inner wall of the connecting shell and enter the locking slot during use, thereby instantly completing the initial locking of the plug and the connecting shell.

[0011] Preferably, one end of the fixing plate abuts against one end of the connecting shell, and the locking rods are symmetrically distributed on both sides of the other end of the plug.

[0012] With the above structure, when in use, the fixed plate and the connecting shell are in close contact, which can prevent dust and moisture from entering the interface through the gap between the plug and the connecting shell, reducing the corrosion of internal circuits by contaminants.

[0013] Preferably, the locking rod is L-shaped, the bottom end of the locking rod is beveled, and the locking rod and the connecting shell are engaged by protrusions.

[0014] With the above structure, during use, the horizontal section of the "L"-shaped locking rod closely abuts against the protrusion. The reverse blocking force of the protrusion on the locking rod directly restricts the axial displacement of the plug, preventing the plug from coming loose from the connecting shell.

[0015] Preferably, the protective structure includes a substrate disposed inside the connecting shell, a heat-conducting layer disposed on one side of the substrate, a wear-resistant layer disposed on one side of the heat-conducting layer, a first shielding layer disposed on the other side of the substrate, a second shielding layer disposed on one side of the first shielding layer, and an insulating layer disposed on one side of the second shielding layer.

[0016] Preferably, the substrate is permalloy, the thermally conductive layer is thermally conductive silicone grease, and the wear-resistant layer is a ceramic coating.

[0017] With the above structure, thermal grease can quickly transfer heat to the external environment during use, avoiding component damage caused by local overheating and extending the service life of the interface.

[0018] Preferably, the first shielding layer is a copper strip, the second shielding layer is a semiconductor shielding paper, and the insulating layer is a polyimide film.

[0019] With the above structure, the polyimide film has excellent electrical insulation properties during use. It can tightly wrap the internal circuit and metal structure of the interface to form a reliable insulation barrier, effectively isolate components with different potentials, and eliminate the risk of short circuit.

[0020] The LVDS interface connection structure for a vehicle instrument panel provided by this utility model has the following advantages:

[0021] By incorporating a connecting structure, the positive engagement of the fixing block and the slot can limit the tendency of the plug to come out along the axial direction of the connecting shell; while the reverse engagement of the "L"-shaped locking rod and the protrusion can counteract the reverse pulling force on the plug when the vehicle vibrates, thus avoiding malfunctions such as screen flickering and blackout caused by vibration.

[0022] By incorporating a protective structure, the permalloy layer of the substrate targets low-frequency magnetic field interference, while the copper strip of the first shielding layer blocks high-frequency electromagnetic radiation through reflection. The semiconductor shielding paper of the second shielding layer further absorbs residual noise, enabling it to cope with complex interference sources and adapt to the strong electromagnetic environment of vehicles.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 The present invention provides a vehicle instrument panel LVDS interface connection structure, including a connection shell 1.

[0031] Reference Figures 1-4As shown, a plug 2 is installed inside the connecting shell 1, and the plug 2 fits into the interior of the connecting shell 1. The output end of the plug 2 is electrically connected to the input end of the connecting shell 1. A first wiring 3 is fixed to one end of the plug 2, and a second wiring 4 is fixed to one end of the connecting shell 1. A connecting structure 5 is fixed to the outside of the plug 2. The connecting structure 5 includes fixing blocks 501 fixed to both sides of one end of the plug 2. The fixing blocks 501 have movable grooves 502 inside, and a locking block 503 is fixed to one side of the fixing blocks 501. Locking grooves 504 are provided on both sides of the interior of the connecting shell 1. A locking block 504 is fixed to the outside of the first wiring 3 at one end of the plug 2. The fixed plate 505 and the plug 2 are both fixed with locking rods 506 on both sides of the other end. The connecting shell 1 is fixed with protrusions 507 on both sides of the other side. The fixing blocks 501 are symmetrically distributed on both sides of one end of the plug 2. The locking blocks 503 are set with bevels on both sides. The locking blocks 503 and the connecting shell 1 form a locking structure through the locking grooves 504. One end of the fixed plate 505 abuts against one end of the connecting shell 1. The locking rods 506 are symmetrically distributed on both sides of the other end of the plug 2. The locking rods 506 are set in an "L" shape. The bottom end of the locking rods 506 is set with bevels. The locking rods 506 and the connecting shell 1 form a locking structure through the protrusions 507.

[0032] Insert the plug 2 into the interior of the connecting shell 1. The locking block 503 on one side of the fixing block 501 has a beveled design on both sides, and the movable groove 502 inside the fixing block 501 provides deformation space for the locking block 503, ensuring that the locking action can be completed smoothly. When inserted, it can smoothly squeeze the inner wall of the connecting shell 1. When the locking block 503 moves to the position of the slot 504, the locking block 503 elastically resets and locks into the slot 504, realizing the initial fixation of one end of the plug 2 to the connecting shell 1. At the same time, the "L"-shaped locking rods 506 on both sides of the other end of the plug 2 approach the protrusions 507 on the corresponding side inside the connecting shell 1 during the insertion of the plug 2. Because the bottom of the locking rod 506 is beveled, when it is inserted, the beveled surface contacts the protrusion 507 and generates a guiding effect, causing the locking rod 506 to deform slightly. When the plug 2 is fully inserted, the locking rod 506 and the protrusion 507 form a reverse engagement, further restricting the axial movement of the plug 2. After the plug 2 is fully inserted, one end of the fixing plate 505 is in close contact with the end of the connecting shell 1, thereby enhancing the fit between the plug and the connecting shell and ensuring the connection stability of the interface under vehicle vibration environment.

[0033] Reference Figure 5As shown, a protective structure 6 is provided inside the connecting shell 1. The protective structure 6 includes a substrate 601 disposed inside the connecting shell 1, a heat-conducting layer 602 disposed on one side of the substrate 601, a wear-resistant layer 603 disposed on one side of the heat-conducting layer 602, a first shielding layer 604 disposed on the other side of the substrate 601, a second shielding layer 605 disposed on one side of the first shielding layer 604, and an insulating layer 606 disposed on one side of the second shielding layer 605. The substrate 601 is permalloy, the heat-conducting layer 602 is thermally conductive silicone grease, the wear-resistant layer 603 is a ceramic coating, the first shielding layer 604 is a copper strip, the second shielding layer 605 is a semiconductor shielding paper, and the insulating layer 606 is a polyimide film.

[0034] The substrate 601 is made of permalloy, which utilizes its high magnetic permeability to effectively shield the LVDS signal from external magnetic fields. Simultaneously, the first shielding layer 604, made of copper strip, blocks electromagnetic radiation through metal shielding, while the second shielding layer 605, made of semiconductor shielding paper, further absorbs noise signals. This dual shielding design significantly reduces the impact of the complex electromagnetic environment in the vehicle on the LVDS signal, preventing signal distortion and abnormal instrument panel display. The thermally conductive layer 602, made of thermally conductive silicone grease, quickly conducts the heat generated between the plug 2 and the connecting shell 1 during signal transmission, dissipating it to the outside through the connecting shell 1 to prevent localized overheating and damage to the interface components. The wear-resistant layer 603 outside the thermally conductive layer 602 is a ceramic coating, enhancing the wear resistance of the protective structure surface, reducing component wear caused by plug insertion / removal or vehicle vibration, and extending the interface's lifespan. The insulating layer 606, made of polyimide film, effectively isolates the internal circuitry of the interface from the external metal structure through its high-temperature resistance and aging resistance, preventing leakage or short-circuit risks, while also adapting to high and low temperature environments in the vehicle, ensuring the electrical safety of the interface.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
