Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and in particular to a shock-resistant and buffered mounting structure for vehicle LCD screens. Background Technology

[0002] In-vehicle LCD screens are the core carriers of automotive intelligence, integrating display, touch, and interactive functions. High-definition panels adapt to the complex in-vehicle environment, displaying information such as navigation and vehicle status. Evolving from a single instrument panel to multi-screen designs, they combine practicality and a high-tech feel. Their installation structure uses a frame support method designed to fix the equipment. Through reasonable layout and connection, and support design, stability is ensured. The installation structure of the in-vehicle LCD screen can stabilize the screen in environments with vehicle vibrations, accurately position it to ensure driving safety, and also protect the screen, which is crucial to ensuring its functionality, safety, and lifespan.

[0003] Vibrations, bumps, and even rapid acceleration and deceleration are inevitable during vehicle operation, all of which continuously impact the LCD screen and its internal precision electronic components and wiring. Without shock absorption measures, prolonged vibration can lead to loosening of internal components, poor wiring connections, display malfunctions, or functional failures. In severe cases, it can even cause the screen to detach or become damaged. Simultaneously, screen shaking can interfere with the driver's vision, increasing distraction and affecting driving safety. Therefore, a shock-absorbing mounting structure for in-vehicle LCD screens is proposed to address these issues. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a shock-absorbing mounting structure for vehicle-mounted LCD screens, aiming to improve the problems of vehicle-mounted LCD screens being damaged by vibration and impact due to the lack of shock-absorbing measures, as well as the interference with the driver's vision.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shock-absorbing mounting structure for a vehicle-mounted LCD screen, comprising a mounting base and a vehicle-mounted LCD screen. Multiple mounting brackets are fixedly connected to the top of the mounting base. A support rod is fixedly connected between two mounting brackets on the same side. Two fixing rings are slidably connected to the outer side of the support rod. A spring is fixedly connected between the two fixing rings. A limit block is fixedly connected to the outer side of the fixing ring. A rotating rod is rotatably connected to the outer side of the limit block. A mounting bracket is rotatably connected to the top of the rotating rod. A support plate is fixedly connected between the multiple mounting brackets. Multiple fixing rods are fixedly connected to the bottom of the support plate. A damper is fixedly connected to the bottom of the fixing rod. A spring is fixedly connected to the outer side of the fixing rod. A protective shell is fixedly connected to the bottom of the vehicle-mounted LCD screen. A rotating assembly is provided on the top of the support plate.

[0006] As a further description of the above technical solution: The rotating assembly includes a support frame, a mounting shell is fixedly connected to the top of the support frame, a second toothed plate is fixedly connected inside the mounting shell, a third spring is fixedly connected inside the mounting shell, a first toothed plate is slidably connected inside the mounting shell, a sliding rod is fixedly connected to the outside of the first toothed plate, a pressing plate is fixedly connected to the outside of the sliding rod, and a connecting plate is fixedly connected to the top of the pressing plate.

[0007] As a further description of the above technical solution: The second spring is fixedly connected to the top of the mounting base on the side away from the support rod.

[0008] As a further description of the above technical solution: The first and second locking plates engage, and the slide rod is slidably connected inside the second locking plate.

[0009] As a further description of the above technical solution: The limiting block is slidably connected to the outside of the support rod.

[0012] As a further description of the above technical solution: The support frame is fixedly connected to the top of the support plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, during the driving process of a car, the in-vehicle LCD screen is subjected to dynamic loads due to road bumps and vehicle vibrations. When the vertical impact force is transmitted to the mounting seat through the car body, the mounting seat generates vertical displacement and compresses the second spring, causing it to undergo elastic deformation and store energy. At the same time, the damper dissipates vibration energy through internal fluid viscous resistance. The two work together to form a viscoelastic buffer system, which effectively attenuates high-frequency vibrations and suppresses resonance effects. The horizontal vibration is transmitted to the rotating rod through the second mounting bracket, forcing the limit block to slide along the fixed rod, driving the fixed ring to compress the first spring, forming a two-stage buffer structure, realizing multi-directional vibration isolation, and effectively buffering the multi-directional vibration of the in-vehicle LCD screen, thereby improving its shock resistance stability.

[0014] 2. In this utility model, when the viewing angle of the display screen needs to be adjusted, pressing the pressing plate drives the sliding rod to move axially, causing the first locking plate to overcome the preload of the third spring and separate from the second locking plate, thus releasing the locked state. At this time, the rotating component enters the free rotation mode, and the user can adjust the pitch angle according to ergonomic requirements. After the angle is determined, the elastic restoring force of the third spring pushes the first locking plate to re-engage, and the angle is locked by utilizing the self-locking characteristic of the involute tooth profile, ensuring a stable display posture in dynamic environments, meeting the driver's need for one-handed blind operation, realizing convenient adjustment and stable locking of the vehicle LCD screen angle, meeting the viewing angle requirements in different usage scenarios, and enhancing operational convenience.

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.

[0018] Reference Figures 1-5This utility model provides an embodiment of a shock-absorbing mounting structure for a vehicle-mounted LCD screen, including a mounting base 1 and a vehicle-mounted LCD screen 22. Multiple mounting brackets 9 are fixedly connected to the top of the mounting base 1. A support rod 2 is fixedly connected between two mounting brackets 9 on the same side. Two fixing rings 3 are slidably connected to the outside of the support rod 2. A spring 5 is fixedly connected between the two fixing rings 3. A limit block 10 is fixedly connected to the outside of the fixing rings 3. A rotating rod 4 is rotatably connected to the outside of the limit block 10. A mounting bracket 12 is rotatably connected to the top of the rotating rod 4. Multiple mounting brackets... A support plate 8 is fixedly connected between the two 12. Multiple fixing rods 11 are fixedly connected to the bottom of the support plate 8. A damper 7 is fixedly connected to the bottom of each fixing rod 11. A spring 6 is fixedly connected to the outside of each fixing rod 11. A protective shell 21 is fixedly connected to the bottom of the vehicle-mounted LCD display 22. A rotating assembly is provided on the top of the support plate 8. The mounting base 1 serves as the basic load-bearing component of the entire structure, used to install the vehicle-mounted LCD display 22 on the vehicle. The vehicle-mounted LCD display 22 is the core object for protection and installation. The mounting bracket 9 stably connects the support rods 2 and the mounting base 1, enhancing... The overall structure is stable. Support rod 2 provides a sliding track for fixed ring 3 and limiting block 10, serving as the supporting skeleton for the lateral buffer structure. Fixed ring 3 converts lateral impact force into the elastic potential energy of springs, achieving lateral buffering. Spring 5 absorbs lateral vibration energy through elastic deformation, mitigating the impact of lateral bumps on the display screen. Limiting block 10 acts as a connector and force transmitter, receiving lateral force transmitted by rotating rod 4. Rotating rod 4 transmits longitudinal and lateral impact forces, dispersing the force on the display screen to the buffer structure. Mounting bracket 12 achieves uniform force distribution and concentration. Support plate 8 serves as a load-bearing and force transfer center. Fixed rod 11 is the connecting hub of the longitudinal buffer structure, transmitting the force on support plate 8 to spring 6 and damper 7. Damper 7 attenuates vibration through damping force, preventing spring resonance and further improving shock resistance, making the buffering more stable. Spring 6 and damper 7 work together to absorb longitudinal vibration energy, enhancing the longitudinal buffering effect. The through holes in protective shell 21 are used for heat dissipation, and data cable connectors are placed inside. The rotating component is used to adjust the angle of the vehicle LCD display screen 22.

[0019] The rotating assembly includes a support frame 13, with a mounting shell 14 fixedly connected to the top of the support frame 13. A second locking plate 17 is fixedly connected inside the mounting shell 14, as is a third spring 15. A first locking plate 16 is slidably connected inside the mounting shell 14, and a sliding rod 18 is fixedly connected to the outer side of the first locking plate 16. A pressing plate 19 is fixedly connected to the outer side of the sliding rod 18, and a connecting plate 20 is fixedly connected to the top of the pressing plate 19. The support frame 13 serves as a connecting bridge between the rotating assembly and the lower buffer structure. The mounting shell 14 provides a closed installation space for the rotating assembly, ensuring orderly cooperation of all components. The toothed plate 17 restricts rotation through the engagement of its toothed structure, ensuring stable fixation after angle adjustment. The spring 15 pushes the toothed plate 16 to engage with the toothed plate 17 through elastic deformation, thus fixing the angle. The toothed plate 16 controls the locking and unlocking of the rotating component through engagement and disengagement, thus fixing and releasing the angle adjustment. The slide rod 18 transmits the force of the pressing plate 19, causing the toothed plate 16 to slide and engage and disengage. The pressing plate 19 is the operating component for angle adjustment, allowing users to control the locking state of the rotating component. The connecting plate 20 enables the rotation operation to directly change the angle of the display screen.

[0020] The side of spring 6 furthest from support rod 2 is fixedly connected to the top of mounting base 1. By being fixed to the top of mounting base 1, it deforms and effectively absorbs vibration energy.

[0021] The first toothed plate 16 and the second toothed plate 17 engage, and the slide rod 18 is slidably connected inside the second toothed plate 17. The engagement can lock the rotating component, ensuring that the angle of the vehicle LCD screen 22 is fixed. The slide rod 18 is used to guide the movement of the first toothed plate 16, ensuring stable engagement and disengagement actions and realizing the angle adjustment function.

[0022] The limiting block 10 is slidably connected to the outside of the support rod 2, so that lateral vibration is compressed by the fixed ring 3 to achieve lateral buffering.

[0023] The connecting plate 20 is fixedly connected to the bottom of the protective shell 21. The connecting plate 20 enables the operation of the rotating component to be directly transmitted to the vehicle LCD screen 22, ensuring that the screen rotates synchronously when the angle is adjusted, thus ensuring the accuracy of the adjustment.

[0024] The side of spring 3 15 closest to slide rod 18 is fixedly connected to the outside of toothed plate 16. By being fixed to the outside of toothed plate 16, spring 3 15 can push toothed plate 16 to complete actions such as resetting.

[0025] The support frame 13 is fixedly connected to the top of the support plate 8. The support frame 13 ensures that the rotating component is stably installed above the buffer structure, thus ensuring the stability of the overall structure when the angle is adjusted.

[0026] Working principle: During vehicle operation, the in-vehicle LCD screen 22 is subjected to dynamic loads due to road bumps and vehicle vibrations. When the vertical impact force is transmitted to the mounting base 1 through the vehicle body, the mounting base 1 generates vertical displacement and compresses the second spring 6, causing it to undergo elastic deformation and store energy. At the same time, the damper 7 dissipates vibration energy through internal fluid viscous resistance. The two work together to form a viscoelastic buffer system, effectively attenuating high-frequency vibrations and suppressing resonance effects. The horizontal vibration is transmitted to the rotating rod 4 through the mounting bracket 12, forcing the limit block 10 to slide along the support rod 2, driving the fixing ring 3 to compress the first spring 5, forming a two-stage buffer structure to achieve multi-directional vibration isolation.

[0027] When the viewing angle of the vehicle LCD screen 22 needs to be adjusted, press the press plate 19 to drive the slide bar 18 to move axially, so that the first locking plate 16 overcomes the preload of the third spring 15 and separates from the second locking plate 17, releasing the locked state. At this time, the rotating component enters the free rotation mode, and the user can adjust the pitch angle according to the ergonomic requirements. After the angle is determined, the elastic restoring force of the third spring 15 pushes the first locking plate 16 to re-engage, and the angle is locked by utilizing the self-locking characteristics of the involute tooth profile, ensuring a stable display posture in dynamic environments and meeting the driver's need for one-handed blind operation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
