A light shield

Abstract

The utility model provides a light shield, and the primary mirror is rotatably arranged at the first mounting position of the cover body and is limited to rotate through the limiting piece, and the secondary mirror cover plate is detachably arranged at the second mounting position of the cover body, and the secondary mirror is detachably arranged at the secondary mirror cover plate. Through the light shield disclosed above, since the primary mirror is rotatably arranged at the first mounting position of the cover body, when the head-up display is installed, the primary mirror can be rotated according to the requirement, and when the primary mirror is rotated to the required position, the rotation of the primary mirror is limited through the limiting piece, so that the optical imaging function of the head-up display can be ensured. Moreover, compared with the existing head-up display, since the primary mirror is integrated on the cover body, the light transmission accuracy of the primary mirror and the secondary mirror can be improved, and the imaging effect of the primary mirror and the secondary mirror is not affected by the assembly error.

Description

Technical Field

[0001] This utility model relates to the automotive field, specifically to a sunshade. Background Technology

[0002] A head-up display (HUD) is a device that uses an internal optical imaging system to display vehicle position, speed, road conditions, and other data directly on the windshield within the driver's field of vision. This virtual image is superimposed on the real road surface, creating a fusion of reality and virtuality. Therefore, the application of HUDs allows drivers to avoid looking down at driving information, significantly improving driving safety.

[0003] As an essential component of a head-up display (HUD), the light shield not only ensures the stability and reliability of the HUD's operation but also guarantees good optical imaging capabilities.

[0004] However, since the imaging effect of the head-up display is also closely related to the windshield, and different windshields have different requirements for the angle of light, the optical scheme and installation structure of the head-up display of each car are different, which leads to the increase in the design cost of the head-up display. Therefore, in order to adapt to the head-up displays of different vehicles, a new sunshade is urgently needed. Utility Model Content

[0005] In view of this, the present invention provides a light shield to solve the problem of excessive design costs caused by the need for existing head-up displays to adapt to different vehicles.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A light shield includes: a primary mirror, a secondary mirror, a secondary mirror cover plate, a shield body, and a limiting member;

[0008] The main mirror can be rotatably mounted in the first mounting position of the housing;

[0009] The limiting component is used to restrict the rotation of the primary mirror;

Detailed Implementation

[0038] 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.

[0039] This utility model embodiment provides a light shield, see [link to relevant documentation] Figure 1 and combined Figures 2 to 7 , Figure 1 The diagram shows the structure of a light shield, which includes: a primary mirror 1, a secondary mirror 2, a secondary mirror cover plate 3, a shield body 4, and a limiting member 5.

[0040] The main mirror 1 is rotatably mounted in the first mounting position of the housing 4;

[0041] Limiting component 5 is used to limit the rotation of the primary mirror 1;

[0042] The secondary mirror cover plate 3 is detachably installed at the second mounting position of the cover body 4;

[0043] Secondary mirror 2 can be detachably mounted on secondary mirror cover plate 3.

[0044] It should be noted that in this application, the primary mirror 1 is rotatably mounted in the first mounting position of the housing 4, the secondary mirror cover 3 is detachably mounted in the second mounting position of the housing 4, and the secondary mirror 2 is detachably mounted in the secondary mirror cover 3, which can ensure that light is reflected from the secondary mirror 2 to the primary mirror 1, and then reflected from the primary mirror 1 to the windshield.

[0045] In this embodiment of the invention, the primary mirror 1 is rotatably mounted in the first mounting position of the housing 4, and the rotation of the primary mirror 1 is restricted by the limiting member 5. The secondary mirror cover 3 is detachably mounted in the second mounting position of the housing 4, and the secondary mirror 2 is detachably mounted on the secondary mirror cover 3. With the aforementioned light shield, since the primary mirror 1 is rotatably mounted in the first mounting position of the housing 4, when installing the head-up display, the primary mirror 1 can be rotated as needed. When the primary mirror 1 is rotated to the desired position, the limiting member 5 restricts its rotation, thus ensuring the optical imaging function of the head-up display. Furthermore, compared to existing head-up displays, since the primary mirror 1 is integrated into the housing 4, the light transmission accuracy between the primary mirror 1 and the secondary mirror 2 can be improved, preventing assembly errors from affecting the imaging effect.

[0046] Specifically, the secondary mirror cover plate 3 includes: a support plate 31, a lower limit plate 32, and an upper limit plate 33;

[0047] The lower limit plate 32 is disposed on the lower side of the support plate 31;

[0048] The upper limit plate 33 is set at a first preset angle on the upper side of the support plate 31. The upper limit plate 33 and the lower limit plate 32 cooperate to fix the secondary mirror 2.

[0049] The upper side of the secondary mirror 2 is provided with a bevel at a second preset angle.

[0050] It should be noted that by setting the upper side of the secondary mirror 2 to a second preset angle and setting the upper limit plate 33 to a first preset angle, after the secondary mirror 2 is inserted into the upper limit plate 33 and the lower limit plate 32, the upper limit plate 33 and the lower limit plate 32 can effectively restrict the secondary mirror 2, thereby preventing the secondary mirror 2 from coming out.

[0051] It should also be noted that the first preset angle and the second preset angle may be the same or different. Those skilled in the art can choose according to their needs. In this application, the first preset angle and the second preset angle are not specifically limited.

[0052] Specifically, the side of the support plate 31 that contacts the secondary mirror 2 is provided with an adhesive application groove 311.

[0053] It should be noted that by opening an adhesive groove 311 on the side of the support plate 31 that contacts the secondary mirror 2, and then applying adhesive in the adhesive groove 311, the secondary mirror 2 and the secondary mirror cover plate 3 can be further fixed, preventing the secondary mirror 2 from coming off the secondary mirror cover plate 3.

[0054] Specifically, the side of the support plate 31 that contacts the secondary mirror 2 is provided with a support rib 34.

[0055] It should be noted that a support rib 34 is provided on the side of the support plate 31 that contacts the secondary mirror 2, for reference. Figure 2 The support rib 34 constrains the back position of the secondary mirror 2 to prevent the movement of the secondary mirror 2 from affecting the optical imaging effect.

[0056] Furthermore, the light shield also includes a limiting rib 35 disposed between the secondary mirror 2 and the lower limiting plate 32.

[0057] It should be noted that the limiting rib 35 between the secondary mirror 2 and the lower limiting plate 32 can make the secondary mirror 2 more tightly locked between the upper limiting plate 33 and the lower limiting plate 32, which can further prevent the secondary mirror 2 from coming off the secondary mirror cover plate 3.

[0058] Specifically, the secondary mirror cover plate 3 is provided with a first snap-fit ​​structure 36;

[0059] The second mounting position is provided with a second snap-fit ​​structure 41 that snaps into the first snap-fit ​​structure 36.

[0060] It should be noted that by providing a first snap-fit ​​structure 36 on the secondary mirror cover plate 3 and a second snap-fit ​​structure 41 that snaps into the first snap-fit ​​structure 36 at the second mounting position, the secondary mirror cover plate 3 can be installed and removed through the cooperation of the first snap-fit ​​structure 36 and the second snap-fit ​​structure 41.

[0061] Specifically, the secondary mirror cover plate 3 is provided with multiple female fasteners;

[0062] The cover 4 is provided with multiple male buckles that correspond one-to-one with multiple female buckles.

[0063] It should be noted that this application provides multiple female buckles on the secondary mirror cover plate 3 and multiple male buckles on the cover body 4 that correspond one-to-one with the female buckles. During assembly, the male buckles of the cover body 4 are engaged with the female buckles, which enables the installation and removal of the secondary mirror cover plate 3.

[0064] It should also be noted that a female buckle can be provided on the secondary mirror cover plate 3 and a male buckle can be provided on the cover body 4, or a male buckle can be provided on the secondary mirror cover plate 3 and a female buckle can be provided on the cover body 4. Those skilled in the art can choose according to their needs.

[0065] Specifically, the secondary mirror cover 3 is fixed to the stud 43 of the cover body 4 by bolts.

[0066] It should be noted that since the secondary mirror cover plate 3 and the housing 4 are assembled by male and female fasteners, there is a certain gap between the secondary mirror cover plate 3 and the housing 4. This gap will cause abnormal noise when the vehicle is in motion and will affect the imaging effect of the head-up display. In order to solve the above problems, this application fixes the secondary mirror cover plate 3 to the stud 43 of the housing 4 with bolts. This can effectively prevent the secondary mirror cover plate 3 from causing the secondary mirror 2 and the main mirror 1 to shake due to vibration during vehicle movement, further ensuring the optical imaging effect of the head-up display and avoiding abnormal noise caused by shaking.

[0067] Specifically, screw holes 37 are provided on the upper limit plate 33 and lower limit plate 32 of the secondary mirror 2, and studs 43 for bolt connection are provided at the second mounting position of the cover 4.

[0068] Specifically, the primary mirror 1 has rotating shafts 11 at both ends;

[0069] The first mounting position has shaft grooves 42 on both sides that mate with the rotating shaft 11;

[0070] The limiting element 5 is provided in the shaft groove 42.

[0071] It should be noted that by setting rotating shafts 11 at both ends of the main mirror 1, and opening shaft grooves 42 on both sides of the first mounting position to cooperate with the rotating shafts 11, and setting the limiting member 5 in the shaft grooves 42, the main mirror 1 can rotate as needed. After the main mirror 1 is adjusted, the rotating shafts 11 are restricted to rotate by the limiting member 5 to prevent the main mirror 1 from rotating during vehicle movement, thus effectively ensuring the optical imaging function of the head-up display.

[0072] Specifically, the limiting component 5 is a spring clip.

[0073] It should be noted that the limiting member 5 can be a spring sheet with a certain toughness (such as a spring sheet made of spring steel), or other components that can limit the rotation of the rotating shaft 11 (such as a rubber sheet). Those skilled in the art can choose according to their needs. However, this application prefers the limiting member 5 to be a spring sheet.

[0074] It is worth noting that the two ends of the spring sheet in this application are fixed to the two sides of the groove 42 by screws, so that the spring sheet and the groove 42 cooperate to clamp the rotating shaft 11, thereby constraining the rotating shaft 11 radially, so as to restrict the rotating shaft 11 from rotating within the groove 42.

[0075] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
