Description

Technical Field

[0001] This utility model relates to the field of automotive head-up display technology, specifically an adjustable-angle automotive navigation display screen. Background Technology

[0002] A head-up display (HUD), also known as a head-up display system, is a driver-centric multi-functional instrument panel. Its main function is to project important driving information, such as vehicle speed and navigation, onto the windshield in front of the driver, allowing them to access this information without looking down or turning their head. This design aims to improve driving safety, especially at high speeds or at night, avoiding potential safety risks caused by looking down at the instrument panel.

[0003] In the existing technology, the display screen of the car navigation system is generally fixed in one piece and installed on the car dashboard. When the driver looks at the screen of the car navigation system, the angle of his line of sight is fixed and the angle between the display screen and the driver cannot be changed. This is very inconvenient for the driver and needs to be changed. Utility Model Content

[0024] Figure 3 This is a schematic diagram of the structure of the adjustment component of this utility model. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] refer to Figure 1-3The present invention provides an adjustable-angle car navigation display screen. According to one embodiment, it includes a display screen body 1, an angle adjustment mechanism 2, and a mounting base 3 for mounting the display screen body 1.

[0027] The angle adjustment mechanism 2 includes:

[0028] Adjustment cavity 21, the adjustment cavity 21 is located inside the adjustment housing, the adjustment housing is located between the display screen body 1 and the mounting base 3, and the bottom surface of the adjustment housing is fixedly connected to the mounting base 3;

[0029] A rotating shaft 22 is rotatably disposed within the adjusting cavity 21 via the rotating shaft 22;

[0030] And an adjustment component 23, which is partially disposed in the adjustment cavity and partially located on one side of the rotating shaft, for adjusting the rotation angle of the rotating shaft 22.

[0031] In a further embodiment, the adjustment component 23 includes a rotating block 231, a rack 232, a gear 233, and a rotation limiter 234, and the adjustment component 23 is fixedly connected to the rack 232 laterally.

[0032] In a further embodiment, the adjustment cavity 21 includes an upper adjustment cavity 211 and a lower adjustment cavity 212, the rotating block 231 is rotatably disposed in the lower adjustment cavity 212, and the rack 232 is rotatably disposed in the lower adjustment cavity 212 and fixedly connected to the rotating block 231;

[0033] In a further embodiment, the rack 232 passes through the lower adjustment cavity 212 and is located in the upper adjustment cavity 211, and the rack 232 is meshed with the gear 233 on the rotating shaft 22.

[0034] In a further implementation, such as Figure 3 As shown, the rotating block 231 is arc-shaped, and a positioning element 2311 is rotatably connected to the end face of the rotating block 231 along the arc. A magnet 2341 is provided on the rotating limiting element 234. The magnet 2341 is arc-shaped and has a groove 2342 and a protrusion 2343. The positioning element 2311 is a metal that attracts the magnet 2341. When the rotating block 231 rotates with the arc, and the positioning element 2311 attracts the protrusion 2343, the display screen body 1 is positioned. To achieve a larger angle, it can continue to rotate based on the original position. This is the clockwise rotation of the display screen body 1.

[0035] In a further embodiment, a positioning head 2312 is provided on the outer side of the positioning member 2311. The positioning head 2312 is arc-shaped and has a first end face 23121 that narrows at both ends.
