Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted equipment technology, and in particular to a vehicle-mounted head-up display and a vehicle. Background Technology

[0002] A head-up display (HUD), also known as a head-up monitor, typically includes at least one reflector. This reflector directs the image light emitted from the HUD's internal image source onto a projection medium, such as a car's windshield or a specially designed screen in the cockpit. This allows the driver or other personnel to see a virtual image of the target object at a specific location after receiving the image light. HUDs can project important driving information, such as speed and navigation, directly in front of the driver, preventing them from looking down at instrument panels or other driver assistance displays and thus increasing driving safety. Currently, HUDs usually include at least one rotating reflector (rotating mirror) that can rotate around an axis to change the imaging position of the virtual image, adapting it to the eye area of ​​different drivers based on their height and posture. However, there is a gap in the rotating structure of the rotating mirror. If the control precision of this gap is insufficient, there may be image jitter caused by excessive gap. The traditional rotating mirror is installed in a ball head or cylindrical shape. The contact surface is generally a hemispherical or hemispherical surface, and the other side is an elastic plane pre-compression. When the vehicle passes through a bumpy road section, the rotating shaft of the rotating mirror will still have elastic jump, and the corresponding image will occasionally jitter. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle head-up display and vehicle, which aims to fix the rotating shaft of the reflector with a rotating mirror bracket, and reduce or eliminate the gap between the rotating shaft and the rotating mirror bracket by adjusting the installation position of the rotating mirror bracket, so as to avoid abnormal noise caused by the gap in the assembly during driving, and solve the problem of excessive assembly gap and difficulty in controlling the precision of the existing reflector structure.

[0004] To achieve the above objectives, this utility model proposes a vehicle head-up display, comprising: a PGU component, a mid-frame, a reflector, and a rotating mirror;

[0005] The PGU component is disposed at the bottom of the middle frame, and the reflector and the rotating mirror are disposed opposite to each other on both sides of the middle frame;

[0006] The reflector is provided with a flat semi-conical rotating shaft at both ends, and the middle frame is provided with adjustable rotating shaft brackets at both ends. The rotating shaft brackets are provided with a flat through hole in the middle that is adapted to the rotating shaft.

[0007] A further technical solution of this utility model is that the vehicle head-up display also includes a motor assembly disposed within the middle frame and engaging with the rotating mirror. The motor assembly is used to drive the rotating mirror to rotate to realize the adjustment of the head-up display gear. The rotation angle is offset from the alignment angle between the rotating mirror and the flat through hole of the rotating mirror bracket.

[0008] A further technical solution of this utility model is that the vehicle head-up display also includes a light shield, which is disposed on the middle frame and is used to eliminate optical stray light.

[0009] A further technical solution of this utility model is that the vehicle head-up display also includes a motherboard assembly, which is disposed at the bottom of the middle frame and electrically connected to the motor assembly and the PGU assembly.

[0010] A further technical solution of this utility model is that the vehicle head-up display also includes a limit switch disposed on the middle frame, and the limit switch is signal connected to the motor assembly.

[0011] A further technical solution of this utility model is that the vehicle head-up display also includes an upper cover assembly disposed above the middle frame.

[0012] To achieve the above objectives, this utility model also proposes a vehicle, which includes the vehicle head-up display as described above.

[0013] The beneficial effects of this utility model of vehicle head-up display and vehicle are:

[0014] Traditional rotating mirror installation methods involve designing the rotating mirror's mounting structure on the mid-frame. Due to the large size of the mid-frame, it is difficult to control the precision of the rotating mirror's mounting position, resulting in a significant installation gap after the rotating mirror is assembled. This invention uses left and right mounting brackets, which have smaller components and are easier to control in terms of precision. Furthermore, the mounting positions of the left and right mounting brackets can be adjusted during installation to minimize or even eliminate the assembly gap, thereby improving the installation precision of the rotating mirror and solving the problem of image jitter caused by insufficient control precision of the rotating structure's gap and excessive gap.

[0031] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] 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.

[0033] This utility model proposes a vehicle head-up display. The technical solution adopted by this utility model is mainly to reduce or eliminate the gap between the rotating shaft and the rotating frame of the mirror by adjusting the installation position of the rotating mirror bracket, so as to avoid abnormal noise caused by the gap during driving. This solves the problem of excessive assembly gap and difficulty in controlling the precision of existing reflectors.

[0034] Specifically, please refer to Figures 1 to 13 The preferred embodiment of the vehicle head-up display of this utility model includes: PGU component 1, middle frame 2, reflector 3 and rotating mirror 4.

[0035] In this embodiment, the middle frame 2 is the main frame of the vehicle head-up display, and the PGU component 1 is disposed at the bottom of the middle frame 2. The PGU component 1 is the imaging unit of the head-up display. The reflector 3 and the rotating mirror 4 are disposed opposite to each other on both sides of the middle frame 2.

[0036] The reflector 3 is provided with a flat semi-conical rotating shaft 5 at both ends, and the middle frame 2 is provided with a rotating shaft 5 bracket at both ends. The middle part of the rotating shaft 5 bracket is provided with a flat through hole that matches the rotating shaft 5.

[0037] The present invention will be described below using the rotating shaft 5 brackets at both ends of the middle frame 2 as examples of the left rotating mirror bracket 6 and the right rotating mirror bracket 7.

[0038] In this embodiment, the left rotating mirror bracket 6 and the right rotating mirror bracket 7 cooperate with the rotating mirror 4 to eliminate gaps and fix the rotating mirror 4 on the middle frame 2. The reflector 3 is an optical imaging unit fixed on the middle frame 2. The rotating mirror 4 is an optical imaging unit, which, together with the left rotating mirror bracket 6 and the right rotating mirror bracket 7, forms a rotating mirror assembly 8 fixed on the middle frame 2 and can rotate around the rotating axis 5 of the rotating mirror 4.

[0039] In this embodiment, the left-turning mirror bracket 6 and the right-turning mirror bracket 7 have semi-conical inner cavities to form the flat through holes. The left-turning mirror bracket 6 and the right-turning mirror bracket 7 have the same structural composition and are symmetrically arranged on both sides of the rotating mirror 4.

[0040] The rotating shafts 5 at both ends of the rotating mirror 4 are assembled with the left rotating mirror bracket 6 and the right rotating mirror bracket 7 in a semi-conical surface contact manner to form a rotating mirror assembly 8. Afterwards, the gap between the rotating shaft 5 of the rotating mirror 4 and the left rotating mirror bracket 6 and the right rotating mirror bracket 7 can be eliminated by adjusting the installation position of the left rotating mirror bracket 6 and the right rotating mirror bracket 7, and then the rotating mirror assembly 8 is fixed on the middle frame 2, so that the rotating mirror 4 can rotate through the flat semi-conical rotating shaft 5.

[0041] Specifically, the rotating shaft 5 of the rotating mirror 4 has a flat semi-conical structure, and the corresponding left rotating mirror bracket 6 and right rotating mirror bracket 7 have flat through holes. After aligning the rotating shaft 5 of the rotating mirror 4 through the flat through holes of the left rotating mirror bracket 6 and right rotating mirror bracket 7, the rotating mirror 4 is rotated at a certain angle to offset the flat through holes of the rotating mirror 4 bracket, thus forming the rotating mirror assembly 8. The left rotating mirror bracket 6 and right rotating mirror bracket 7 are provided with screw through holes. When installing to the middle frame 2, the installation positions of the left rotating mirror bracket 6 and right rotating mirror bracket 7 can be adjusted to reduce or eliminate the gap between the rotating shaft 5 and the left rotating mirror bracket 6 and right rotating mirror bracket 7, and then the left rotating mirror bracket 6 and right rotating mirror bracket 7 are fixed to the middle frame 2 with screws.

[0042] For example, when assembling the rotating mirror assembly 8, the left rotating mirror bracket 6 can be assembled first, and then the right rotating mirror bracket 7 can be moved to the assembly limit position and installed. Since the rotating shaft 5 of the rotating mirror 4 contacts the left rotating mirror bracket 6 and the right rotating mirror bracket 7 with a semi-conical surface, the installation gap between the rotating shaft 5 of the rotating mirror 4 and the rotating mirror 4 bracket can be eliminated to the greatest extent.

[0043] Furthermore, in this embodiment, the vehicle head-up display also includes a motor assembly 9 disposed within the middle frame 2 and meshing with the rotating mirror 4. The motor assembly 9 is arranged at the bottom of the rotating mirror 4 and fixed on the middle frame 2. The motor assembly 9 is used to drive the rotating mirror 4 to rotate to realize the adjustment of the head-up display position. The rotation angle is offset from the alignment angle between the rotating mirror 4 and the flat through hole of the rotating mirror 4 bracket, thereby avoiding jamming between the rotating shaft 5 of the rotating mirror 4 and the flat hole of the rotating mirror 4 bracket when the rotating mirror 4 is rotated.

[0044] Furthermore, in this embodiment, the vehicle head-up display also includes a light shield 10, which is disposed on the middle frame 2 to eliminate optical stray light.

[0045] Furthermore, in this embodiment, the vehicle head-up display also includes a mainboard assembly 11, which is disposed at the bottom of the middle frame 2 and electrically connected to the motor assembly 9 and the PGU assembly 1.

[0046] Furthermore, in this embodiment, the vehicle head-up display also includes a limit switch 12 disposed on the middle frame 2. The limit switch 12 is signal-connected to the motor assembly 9 and serves as a control switch for the head-up display.

[0047] Furthermore, in this embodiment, the vehicle head-up display also includes an upper cover assembly 13 disposed above the middle frame 2, the upper cover assembly 13 being the outer shell of the head-up display.

[0048] In summary, the beneficial effects of this vehicle-mounted head-up display are:

[0049] Traditional rotating mirror installation methods involve designing the rotating mirror's mounting structure on the mid-frame. Due to the large size of the mid-frame, it is difficult to control the precision of the rotating mirror's mounting position, resulting in a significant installation gap after the rotating mirror is assembled. This invention uses left and right mounting brackets, which have smaller components and are easier to control in terms of precision. Furthermore, the mounting positions of the left and right mounting brackets can be adjusted during installation to minimize or even eliminate the assembly gap, thereby improving the installation precision of the rotating mirror and solving the problem of image jitter caused by insufficient control precision of the rotating structure's gap and excessive gap.

[0050] To achieve the above objectives, this utility model also proposes a vehicle, characterized in that the vehicle includes a vehicle head-up display as described in the above embodiments. The structure and working principle of the vehicle head-up display have been described in detail above and will not be repeated here.
