Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, specifically to an adjustable-angle vehicle display. Background Technology

[0002] With the rapid development of intelligent cockpits and in-vehicle entertainment systems, in-vehicle displays have become key components for enhancing the driving and riding experience. Among these, displays designed for rear passengers are often installed behind the headrests of the front seats to play audio-visual content, provide navigation information, or facilitate other interactions, greatly enriching the riding experience during long journeys or daily commutes. To accommodate different passenger heights and seating preferences, and to avoid screen glare, these displays require flexible and reliable multi-dimensional adjustment capabilities, including horizontal extension / retraction, vertical height adjustment, and tilt adjustment.

[0003] Currently, most adjustable vehicle displays on the market use ball joints, universal joints, or simple pivot structures to achieve angle adjustment, and slide rails or telescopic rods to achieve position adjustment. However, these existing technologies still have many shortcomings in practical applications: First, in terms of installation versatility, many products use fixing clips that match the headrest pillars of specific car models, lacking the ability to adapt to pillars with different spacing, resulting in poor product versatility and a cumbersome installation process. Second, in terms of adjustment function and stability, although the common ball joint structure can achieve multi-angle adjustment, it often has the problem of insufficient locking force, which can easily cause angle slippage in the vibration environment of vehicle driving, affecting viewing. Simple pivot structures can usually only achieve single-direction rotation, with limited adjustment dimensions, and cannot meet the needs of multi-angle viewing. Furthermore, in terms of telescopic adjustment mechanisms, many designs use telescopic rods without locking or with simple friction locking, which have the problems of easy slippage after adjustment and inaccurate positioning. Moreover, the adjustment process may require two-hand operation, which is not convenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable-angle vehicle display screen. It solves the problem that many existing products use fixed clips that match the headrest pillars of specific car models, lacking adaptability to pillars with different spacing, resulting in poor product versatility and cumbersome installation. Secondly, regarding adjustment function and stability, while common ball hinge structures can achieve multi-angle adjustment, they often suffer from insufficient locking force, easily causing angle slippage in the vibration environment of a moving vehicle, affecting viewing. Simple pivot structures typically only allow for single-direction rotation, limiting adjustment dimensions and failing to meet the needs of multi-angle viewing. Furthermore, many designs use telescopic adjustment mechanisms with no locking or simple friction locking telescopic rods, which are prone to slippage after adjustment, inaccurate positioning, and may require two-handed operation, resulting in insufficient convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle vehicle display screen, comprising a cylindrical body and a display screen body. The cylindrical body has an open structure at both ends, with movable rods inserted at both ends. One end of each movable rod is exposed outside the cylindrical body and fixedly mounted with a first U-shaped plate. A second U-shaped plate is hinged to the first U-shaped plate, and the first U-shaped plate and the second U-shaped plate are connected by a first bolt. A limiting component is provided between the cylindrical body and the movable rods. A plug cylinder is fixedly mounted on the outer front wall of the cylindrical body, and a plug rod is inserted inside the plug cylinder. A rack is fixedly mounted on the lower wall of the plug rod, and a limiting device is provided on the outer lower wall of the plug cylinder. A connecting plate is fixedly mounted on the rear wall of the display screen body, and a pair of arc-shaped plates are fixedly mounted on the connecting plate. The plug rod is rotatably connected between the arc-shaped plates, and an angle adjustment component is provided between the arc-shaped plates and the plug rod.

[0006] Preferably, the angle adjustment component includes a plurality of limiting holes, and limiting grooves are respectively opened on the two side walls of the insertion rod. Limiting pins are inserted into the limiting holes, and the other end of the limiting pins is inserted into the limiting grooves. The plurality of limiting holes are evenly distributed on the arc plate with the center of the arc plate as the center.

[0007] Preferably, the limiting device includes a box body, which is fixedly installed on the lower outer wall of the insert. The lower and upper walls of the box body and the lower wall of the insert have through holes. A pull rod is inserted into the through holes. The upper end of the pull rod is located inside the insert and is fixedly installed with a toothed key. The toothed key matches a rack. The lower end of the pull rod is exposed outside the box body and is fixedly installed with a pull ring. A limiting plate is fixedly installed on the pull rod. A spring is fixedly installed between the limiting plate and the lower inner wall of the box body. The spring is fitted onto the pull rod.

[0008] Preferably, the longitudinal cross-sectional shape of the key is a right-angled triangle, and the longitudinal cross-sectional shape of the teeth on the rack is a right-angled triangle.

[0009] Preferably, the limiting component includes a sliding groove, which is formed on the front wall of the moving rod. A slider is fixedly installed on the inner front wall of both ends of the cylinder. The moving rod is slidably installed on the slider through the sliding groove. A threaded hole is formed on the front wall of the cylinder, which passes through the slider. A second bolt is screwed into the threaded hole. A pressure plate is rotatably installed at the lower end of the second bolt. The pressure plate is in contact with the sliding groove.

[0010] Preferably, the groove has a dovetail groove cross-section and the slider has a dovetail block cross-section. Beneficial effects

[0011] This invention provides an adjustable-angle vehicle display screen. It features an open-ended cylindrical body with a slidable movable rod inserted within it. The end of the movable rod is connected by a first U-shaped plate, a second U-shaped plate, and a first bolt, forming an openable clamping structure. This design allows the distance between the U-shaped plates on both sides to be flexibly adjusted according to the actual distance between the pillars on both sides of the front seat headrest in different vehicle models, while ensuring a secure clamping. Compared to existing technologies that use fixed clips for specific pillar spacing, this invention significantly improves the product's versatility, adapting to the vast majority of vehicle models and simplifying the installation process. Users do not need to purchase a specific model or perform complex modifications. This utility model clearly separates and organically combines the functions of fixing, horizontal extension, vertical height adjustment, and tilt angle adjustment of the display screen through a modular structure. Horizontal extension (i.e., installation width adjustment) is achieved by sliding the moving rod inside the cylinder and locked by an independent limiting component (the second bolt drives the pressure plate to press the dovetail groove structure) to prevent retraction under vehicle vibration. Vertical height adjustment is achieved by inserting and withdrawing the plug rod inside the plug cylinder, using the meshing of the rack and key for one-way locking, and the spring provides continuous clamping force to effectively prevent the display screen from sliding down due to its own weight or vibration, ensuring stable height maintenance. Tilt angle adjustment is achieved by rotating the plug rod between the arc plates, and fixing it by inserting the limiting pin into the limiting holes and limiting grooves at different positions. Each adjustment dimension is independent of each other and does not interfere with each other, and each has a reliable mechanical locking mechanism to ensure the stability of the display screen in any adjustment state and improve the viewing experience. The adjustment mechanisms of this invention are ergonomically designed and intuitive to operate. During installation, simply pull open the U-shaped plate to clamp the column and tighten the first bolt. To adjust the horizontal width, slide the moving rod to the appropriate position and tighten the second bolt. To adjust the height, simply pull down the pull ring with one hand to separate the gear key from the rack, allowing free pushing and pulling of the insertion rod. After releasing the pull ring, the gear key automatically engages and locks under spring action, achieving fast and precise stepless or geared adjustment. To adjust the angle, pull out the limit pin, rotate the display screen to a comfortable angle, and then insert the limit pin into the corresponding limit hole. The entire process is clear and straightforward, requiring no complex tools, and some operations can be completed with one hand, greatly improving the convenience and user experience of adjustment.
