Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically a dual-fixed vehicle-mounted LED display. Background Technology

[0002] Most existing in-vehicle displays are directly fixed to the center console with screws, which is inconvenient to install and remove and has poor stability. When the vehicle is moving or the user touches the screen, the display is prone to shaking, which affects the user experience. Although the traditional magnetic fixing method can be quickly installed and removed, it cannot meet the impact resistance requirements of the in-vehicle environment.

[0003] Therefore, there is a need for an in-vehicle display device that combines quick assembly and disassembly with multi-dimensional stable fixation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dual-fixed vehicle-mounted LED display screen, which solves the problem of stable installation of vehicle-mounted displays and facilitates disassembly and installation through snap-fit ​​and magnetic attraction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-fixed vehicle-mounted LED display screen, comprising a display screen body, a connecting mechanism on the back of the display screen body, a fixing mechanism being snapped onto the connecting mechanism, and the fixing mechanism being connected to the vehicle's central control unit by screws; magnetic attraction mechanisms are provided on both sides of the lower end of the display screen body, the magnetic attraction mechanisms magnetically engaging with the fixing mechanism, and the cooperation between the connecting mechanism and the magnetic attraction mechanism makes the installation of the display screen body more stable.

[0006] Furthermore, the connecting mechanism includes a connecting seat, a limiting plate is provided on the outer side of the lower end of the connecting seat, an insert plate is provided on the inner side of the lower end of the connecting seat, a locking strip is provided on the inner end of the insert plate, and a push plate is connected to the bottom of the insert plate.

[0007] Furthermore, the fixing mechanism includes a fixing base, with limit stops fixed on both sides of the inner end of the fixing base, and a locking block fixed inside the limit stop that slides with the locking strip, and a positioning block provided at the lower end of the locking block.

[0008] Furthermore, the magnetic attraction mechanism includes mounting rings installed on both sides of the display screen body, with connecting seats threaded inside the mounting rings, magnetic blocks provided on the outer side of the connecting seats, and fixing plates on both sides of the fixing seats that magnetically engage with the magnetic blocks.

[0009] Furthermore, the push plate is located below the display screen body. Pushing the push plate inward can deform the insert plate, causing the card strip to detach from the card block and the positioning block.

[0010] Furthermore, the upper end of the fixed base is provided with a support plate, the support plate is inclined, the upper end of the support plate is fixed with a positioning pin, and the upper back of the display screen body is provided with a mounting block that is inserted into the positioning pin.

[0011] Furthermore, a spring plate is provided between the limiting plate and the insert plate, and the end of the spring plate is fixedly connected to the limiting plate.

[0012] This invention provides a dual-fixed vehicle-mounted LED display screen. Compared with the prior art, it has the following advantages:

[0013] This dual-fixed vehicle-mounted LED display screen achieves three-dimensional stability through a dual fixing mechanism of snap-fit ​​and magnetic attraction, effectively suppressing three-dimensional shaking; the inclined support plate and positioning pin form a triangular support structure, enhancing the display screen's pressure resistance; the push plate linkage deformation design enables quick one-handed assembly and disassembly, improving maintenance convenience; the magnetic attraction mechanism adopts a threaded adjustment structure, which can be adapted to fixing plates of different thicknesses; the limit stop and positioning block form a double stop, ensuring the reliability of the snap-fit.

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a dual-fixed vehicle-mounted LED display screen; specifically, it consists of a display screen body 1, which is a known prior art and will not be described in detail here. The existing vehicle-mounted display screen body 1 is placed in the vehicle by temporary fixing. A connecting mechanism is fixed on the back side of the display screen body 1, and a fixing mechanism is matched and snapped onto the connecting mechanism. The fixing mechanism is fastened to the vehicle's central control position by screws. Magnetic attraction mechanisms are provided on both sides of the lower end of the display screen body 1. The magnetic attraction mechanisms are matched and magnetically attracted to the fixing mechanism, which can stabilize both sides of the display screen body 1. The display screen body 1 is stabilized by the magnetic attraction mechanism, so it is stable and does not shake when the surface of the display screen body 1 is pressed.

[0023] The connecting mechanism includes a connecting seat 2, a limiting plate 3 fixed on the lower outer edge of the connecting seat 2, an insert plate 4 fixed on the lower inner edge of the connecting seat 2, and a locking strip 5 fixed on the inner end of the insert plate 4. When the display screen body 1 is installed, the insert plate 4 is inserted from the upper end of the fixing mechanism downwards, and the locking strip 5 on the inner side of the insert plate 4 is matched and locked with the fixing mechanism, so that the display screen body 1 can be installed and fixed.

[0024] The fixing mechanism includes a fixing base 7, with limit stops 8 fixedly connected to both sides of the inner end of the fixing base 7. A locking block 9 is fixed inside the limit stop 8. The locking block 9 and the locking strip 5 are matched and slidably set. A positioning block 10 is fixed at the lower end of the locking block 9. When the locking strip 5 slides past the locking block 9, the lower end of the locking strip 5 abuts against the positioning block 10, thus locking and fixing it. A push plate 18 is fixed at the lower end of the insertion plate 4. The push plate 18 is set below the display body 1. By pushing the push plate 18 inward, the insertion plate 4 can be deformed inward. When the insertion plate 4 is deformed, the locking strip 5 can be separated from the positioning block 10 and the locking block 9. Then, the display body 1 can be pulled out upward.

[0025] The magnetic attraction mechanism includes mounting rings 11 fixed to both sides of the lower end of the display body 1. A connecting seat 12 is threaded into the mounting ring 11. A magnetic block 13 is fixed to the outer end of the connecting seat 12. Fixing plates 15 are fixed on both sides of the fixing seat 7. The fixing plates 15 and the magnetic block 13 are magnetically attracted. This can improve the fixed stability of the display body 1 through the magnetic block 13 and the fixing plate 15. When operating the two sides of the end face of the display body 1, the display body 1 will not shake left and right due to pressing. The connecting seat 12 with threaded connection can facilitate the disassembly of the magnetic block 13.

[0026] An inclined support plate 16 is fixed to the upper end of the fixed base 7, and a positioning pin 17 is fixed to the upper end of the support plate 16. An installation block 14 is fixed to the upper back side of the display screen body 1. The installation block 14 is inserted into the positioning pin 17, and the installation block 14 and the positioning pin 17 further support the stability of the display screen body 1. A spring plate 6 is fixed between the limiting plate 3 and the insertion plate 4. The spring plate 6 facilitates the rebound of the insertion plate 4 and improves the stability of the installation.
