Description

Technical Field

[0001] The utility model relates to the technical field of head-up display, specifically to a vehicle-mounted head-up display. Background Art

[0002] Head-up display, abbreviated as HUD, also known as the head-up display system, refers to a vehicle driver-centric, blind-operated, multi-function instrument panel. Its function is to project important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see important driving information such as speed and navigation without lowering or turning his head.

[0003] With the advancement of technology, more and more cars are equipped with head-up display function before leaving the factory. However, for some models that do not have this function before leaving the factory, it is necessary to install an in-vehicle head-up display so that the driver can experience this function.

[0004] The existing vehicle-mounted head-up display is installed above the dashboard of the driver's seat through the adhesive backing provided on the base. This will make the position of the installed head-up display unable to be changed, and thus the position where the image is projected onto the front windshield cannot be changed. Unplugging and reinstalling will cause the viscosity of the adhesive backing to decrease, which is not conducive to stability during long-term use and will seriously affect driving safety.

[0005] For this purpose, a vehicle-mounted head-up display is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1: An adhesive backing 2 is installed at the bottom of the base 1, a mounting groove 4 is opened inside the base 1, a first screw rod 5 is installed inside the mounting groove 4, a first slider 3 is sleeved on the outer side of the first screw rod 5, the first slider 3 and the first screw rod 5 are connected by threaded engagement, a first knob 6 is installed on one side of the base 1, the output end of the first knob 6 extends into the mounting groove 4 and is connected to one end of the first screw rod 5, a fixing block 9 is installed at the top of the first slider 3, a hinge key 14 is installed at one end of the top of the fixing block 9, a connecting block 11 is hinged inside the hinge key 14, and a head-up display device 7 is installed at one end of the connecting block 11.

[0022] Specifically, Figure 1 and Figure 2 As shown, since the bottom of the base 1 is provided with an adhesive backing 2, the entire base 1 can be installed above the instrument panel through the adhesive backing 2, so that the entire base 1 can be installed at an approximate position above the instrument panel, and then the first screw rod 5 can be driven to rotate by rotating the first knob 6. Since a first slider 3 is sleeved on the outer side of the first screw rod 5, and the first slider 3 and the first screw rod 5 are connected by threaded engagement, when the first screw rod 5 rotates, the first slider 3 will move along the installation direction of the first screw rod 5. Since the top of the first slider 3 extends out of the installation groove 4, and the top of the first slider 3 is installed with a head-up display device 7 through a fixing block 9, when the first slider 3 moves, it will drive the head-up display device 7 to move synchronously. By adjusting the position of the head-up display device 7, it can be ensured that the picture can be projected onto the front windshield of the car, thereby avoiding the need to disassemble and reinstall the entire device, ensuring the stability of the device after installation, and improving the flexibility of use.

[0023] Embodiment 2: A projection screen 10 is installed on the top of the head-up display device 7, and the area of ​​the projection screen 10 is smaller than the area of ​​the head-up display device 7. A second screw rod 13 is installed inside the fixed block 9, and a second slider 15 is sleeved on the outer side of the second screw rod 13. The second slider 15 is connected to the second screw rod 13 by threaded engagement, and a support rod 8 is hinged to the top of the second slider 15. The top of the second slider 15 extends out of the fixed block 9, and one end of the support rod 8 is hinged to the bottom of the head-up display device 7. A second knob 12 is installed at one end of the fixed block 9, and the output end of the second knob 12 extends into the fixed block 9 and is connected to one end of the second screw rod 13. A support slide rod 16 is installed on both sides of the bottom end of the fixed block 9, and a limiting slide groove 17 is opened on both sides of the top of the base 1, and the bottom ends of the two support slide rods 16 are slidably installed in the limiting slide groove 17.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since a hinge key 14 is installed on one side of the top of the fixing block 9, and the inside of the hinge key 14 is hinged to the connecting block 11, and one end of the connecting block 11 is connected to one side of the head-up display device 7, the head-up display device 7 can rotate around the hinge key 14. Since the bottom of the head-up display device 7 is hinged with a support rod 8, and one end of the support rod 8 is hinged to the top of the second slider 15, and at the same time, the second slider 15 is sleeved on the outside of the second screw rod 13 and is connected to the second screw rod 13 through a threaded engagement, the second slider 15 can be driven to move along the installation direction of the second screw rod 13 by the rotation of the second screw rod 13. When the second slider 1 After the movement occurs, the head-up display device 7 can be driven to rotate by the supporting effect of the support rod 8, so as to adjust the projection angle of the projection screen 10. Since the installation angles of the front windshields of different car models are different, the head-up display can be adapted to different car models by adjusting the projection angle of the head-up display device 7. Since the bottom ends of the support slide bars 16 installed on both sides of the bottom end of the fixing block 9 are slidably installed inside the limiting slide groove 17, when the fixing block 9 slides above the base 1, the bottom ends of the support slide bars 16 will slide along the opening direction of the limiting slide groove 17, so as to ensure the sliding stability of the fixing block 9 and enhance the overall strength of the device.

[0025] Working principle: When in use, the entire device is installed at the approximate position above the dashboard of the driver's seat through the adhesive backing 2 provided at the bottom of the base 1, and then the first knob 6 is rotated to drive the first screw rod 5 to rotate. When the first screw rod 5 rotates, the first slider 3 moves along the installation direction of the first screw rod 5. When the first slider 3 moves, it will drive the head-up display device 7 to move synchronously. By adjusting the position of the head-up display device 7, it can be ensured that the picture can be projected onto the front windshield of the car. Then, the second slider 15 can be driven to move along the installation direction of the second screw rod 13 by rotating the second screw rod 13. When the second slider 15 moves, the head-up display device 7 can be driven to rotate through the supporting effect of the support rod 8, thereby adjusting the projection angle of the projection screen 10. By adjusting the projection angle of the head-up display device 7, the head-up display can be adapted to different models.
