[0002] A head-up display, abbreviated as HUD, is a display device used in automobiles that can project important information onto the front windshield of the automobile, enabling the driver to see important information without having to look down, thereby improving driving safety performance.

[0003] When the existing HUD is in use, in order to facilitate its use, an adjustment mechanism is usually provided to adjust the angle of the reflector, thereby adjusting the height of the projected image of the HUD. However, the existing technology cannot adjust the horizontal position of the projected image of the HUD, so it is impossible to perform multi-angle adjustment according to the driving habits of different drivers.

[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an automotive HUD with an adaptive angle adjustment mechanism.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: An automotive HUD with an adaptive angle adjustment mechanism includes a base. At both ends of the surface of the base, there are vertically arranged support rods. At the bottom ends of the two support rods, there is a first rotating shaft rotatably connected to the surface of the base. Between the two support rods, there is a reflector. On both sides of the reflector, there is a second rotating shaft rotatably connected between the two support rods. It also includes a first adjustment component for controlling the support rods to rotate around the first rotating shaft, and a second adjustment component for controlling the reflector to rotate around the second rotating shaft.

The driving member includes a sliding block slidably connected in the sliding groove. On the side of the sliding block facing the connecting rod, there is a groove. On one side of the connecting rod, there is a driving rod. The driving rod is inserted into and slides in the groove. An electric push cylinder for driving the sliding block is arranged on the surface of the base.

[0009] The present invention is further provided as: A limiting rod is arranged in the sliding groove. The sliding block is provided with a limiting groove for the limiting rod to pass through and slidably connect.

[0010] The present invention is further configured such that: a fixed block is provided on one side of the sliding block extending out of the sliding block, and electric push cylinders are provided on both sides of the base surface where the fixed block is located, and the ends of the electric push cylinders face the fixed block.

[0011] The present invention is further configured such that: a contact rod is provided at the end of the driving rod, and its diameter is smaller than that of the driving rod, and a space for it to slide is left between the end of the contact rod and the inner wall of the groove.

[0012] The present invention is further configured such that: a first spring is sleeved on the contact rod, and both ends of the first spring are respectively connected to the end of the driving rod and the inner wall of the groove.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0025] As shown in the figure, an automotive HUD with an adaptive angle adjustment mechanism includes a base 1. Vertical support rods 2 are provided on both ends of the surface of the base 1. The bottom ends of the two support rods 2 are provided with a first rotating shaft 3 rotatably connected to the surface of the base 1. A reflector 4 is provided between the two support rods 2. Second rotating shafts 5 rotatably connected between the two support rods 2 are provided on both sides of the reflector 4. It further includes a first adjustment component for controlling the rotation of the support rod 2 with the first rotating shaft 3 as the axis, and a second adjustment component for controlling the rotation of the reflector 4 with the second rotating shaft 5 as the axis.

[0026] During the use of the automotive HUD, the first adjustment component can be used to control the rotation of the reflector 4 with the first rotating shaft 3 as the axis, so as to adjust the angular position of the reflector 4 in the vertical direction, and then adjust the height position of the HUD projection screen. When it is necessary to adjust the horizontal position of the HUD projection screen for different drivers or in different usage scenarios, the second adjustment component can be used to drive the two support rods 2 to deflect with the second rotating shaft 5 as the axis, so as to adjust the angular position of the reflector 4 in the horizontal direction, and then adjust the horizontal position of the HUD projection screen, improving the applicable range of the automotive HUD.

[0027] The first adjustment component includes a connecting rod 6. The two ends of the connecting rod 6 are respectively hinged to the two support rods 2. It further includes a driving member for driving the connecting rod 6 to move along its length direction. A connecting block 17 is provided at the bottom of one side of the support rod 2. The first rotating shaft 3 is provided at the bottom of the connecting block 17. The connecting rod 6 is provided on the side of the support rod 2 away from the connecting block 17. By driving the connecting rod 6 to move, the two support rods 2 can be simultaneously driven to deflect towards the same side, so as to drive the reflector 4 to deflect in the horizontal direction.

[0028] A sliding groove is formed in the surface of the base 1 along its length direction. The driving member includes a sliding block 7 slidably connected in the sliding groove. A groove 8 is formed on one side of the sliding block 7 facing the connecting rod 6. One side of the connecting rod 6 is provided with a driving rod 9. The driving rod 9 is inserted into and slides in the groove 8. An electric push cylinder 10 for driving the sliding block 7 is arranged on the surface of the base 1. When the electric cylinder drives the sliding block 7 to slide along the sliding groove, the driving rod 9 and the connecting rod 6 are driven to move simultaneously.

[0029] A limiting rod 11 is arranged in the sliding groove. The sliding block 7 is provided with a limiting groove for the limiting rod 11 to pass through and slidably connect, so as to ensure the stability of the sliding block 7 during operation.

[0030] One side of the sliding block 7 extending out of the sliding block 7 is provided with a fixed block 12. Electric push cylinders 10 are arranged on both sides of the surface of the base 1 where the fixed block 12 is located. The ends of the electric push cylinders 10 face the fixed block 12. The end of the driving rod 9 is provided with an abutting rod 13, whose diameter is smaller than that of the driving rod 9. A space for the abutting rod 13 to slide is left between the end of the abutting rod 13 and the inner wall of the groove 8. A first spring 14 is sleeved on the abutting rod 13. The two ends of the first spring 14 are respectively connected to the end of the driving rod 9 and the inner wall of the groove 8.

[0031] When the ends of the piston rods of the two electric cylinders are both far away from the fixed block 12, the sliding block 7 is in the middle position. Under the action of the elastic force of the first spring 14, the connecting rod 6 is in a position far away from the sliding block 7, so as to ensure that the support rod 2 can maintain the state of not deflecting, so that the reflector 4 can stably be in the initial middle position. When it is necessary to adjust the horizontal position of the projection screen, the piston rod of one of the electric cylinders moves towards the fixed block 12 and pushes the fixed block 12 and the sliding block 7 to slide along the sliding groove, so as to drive the two support rods 2 to deflect towards one side. During the deflection process, the driving rod 9 approaches the inner wall of the groove 8, so that the first spring 14 is compressed.

[0032] A second spring 15 is sleeved between the end inner wall of the sliding groove where the limiting rod 11 is located and the sliding block 7. When the horizontal position of the reflector 4 is adjusted, one of the second springs 15 is compressed. When it is necessary to restore the reflector 4 to the initial middle position, by resetting the two electric cylinders, under the action of the elastic forces of the first spring 14 and the second spring 15, it can be ensured that the sliding block 7 and the connecting rod 6 are reset, and the reflector 4 is in the middle position in the horizontal direction.

[0033] The second driving assembly includes an electric telescopic rod 16. One end of the electric telescopic rod 16 is hinged to one side of the support rod 2, and the other end is hinged to one side of the reflector 4. By the telescopic movement of the electric telescopic rod 16, the reflector 4 is controlled to rotate at a vertical angle, so as to control the position of the HUD projection screen in the vertical direction.

[0034] The specific embodiments are only explanations of the present invention and are not limitations thereof. After reading this specification, those skilled in the art may make modifications to these embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
