[0025] See Figures 1 to 5This utility model provides an automotive instrument cluster with anti-glare protection, including a mounting housing 1 and a front extended sunshade 3. The mounting housing 1 houses the electrical components of the instrument cluster. The front extended sunshade 3 is located at the edge of the front end of the mounting housing 1. A cover mounting bracket 5 is provided at the front end of the front extended sunshade 3. An anti-detachment frame 4 is provided at the connection between the cover mounting bracket 5 and the edge of the front extended sunshade 3. An anti-glare protective cover 6 is provided on the cover mounting bracket 5. A first side sunshade 8 is provided on the left side of the front panel of the mounting housing 1. A first auxiliary limiting cover 9 is provided at the upper right corner of the first side sunshade 8. A second auxiliary limiting cover 10 is provided to the right of the first auxiliary limiting cover 9. The right end of the panel is provided with a second side-mounted sunshade 11. The bottom of the mounting housing 1 is provided with multiple sets of plug-in ears 7. The rear end of the mounting housing 1 is provided with a rear protective shell 2. In this solution, the mounting housing 1 is used as a support and setting device for the instrument cluster. The electrical components for instrument control and display are set inside the mounting housing 1 to achieve the limited installation of each electrical component and connection line. The front edge of the mounting housing 1 is fixed to the installation of the front extension sunshade 3. The housing of the front extension sunshade 3 extends from bottom to top, that is, the top of the housing of the front extension sunshade 3 protrudes from the bottom. The left and right side walls of the front extension sunshade 3 are respectively in a forward-extending posture so as to provide anti-glare protection for the instrument cluster during vehicle driving.

[0026] The front-mounted extended light shield 3, together with the anti-detachment frame 4, establishes a fixed installation on the housing mounting bracket 5, thus limiting the installation of the front-mounted extended light shield 3 on the housing mounting bracket 5. The front-mounted extended light shield 3, through the housing mounting bracket 5, establishes the installation of the anti-glare protective cover 6. The anti-glare protective cover 6 is positioned in front of the instrument cluster and along the housing direction of the front-mounted extended light shield 3, providing anti-glare protection for the instrument cluster. The first side-mounted light shield 8 protrudes from the upper left corner of the housing, effectively protecting the instrument at that location. The outer side is protected against light, and the second side-mounted light shield 11 is protruding at the upper right corner of the housing, which can also effectively protect the outer side of the instrument. The first auxiliary limit cover 9 and the second auxiliary limit cover 10 are protected by the front extended light shield 3 and the two sets of side-mounted light shields, which can effectively prevent the external light from having a negative impact on the display of these two instruments. The frame between the two sets of side-mounted light shields is also protected by the front extended light shield 3 and the two sets of side-mounted light shields, which effectively ensures the normal display of each instrument icon.

[0027] See Figure 2The anti-glare protective cover 6 includes a transparent cover 61. A convex lens 64 is provided at the rear end of the transparent cover 61. An adhesive layer 63 is provided at the connection between the outer edge of the convex lens 64 and the transparent cover 61. A fixed frame 62 is provided at the outer end of the transparent cover 61. The anti-glare protective cover 6 uses the transparent cover 61 as a protective barrier between the instrument cluster and the external environment. The transparent cover 61 serves as the main support structure of the anti-glare protective cover 6. Its structure is a common transparent protective cover. The outer edge of the transparent cover 61 is embedded in the cover mounting frame 5 through the fixed frame 62. The cover mounting frame 5 fixes it to the front end of the front extension glare shield 3. The transparent cover 61 establishes a fixed setting for the convex lens 64 through the adhesive layer 63. When the instrument cluster icons are powered on, they are controlled by a signal to emit light. The light source display effect can be focused by the convex lens 64 to enhance the focusing effect of the instrument icons, making it easier for the driver to observe the instrument display information.

[0028] See Figure 1 At the corner of the mounting housing 1, there is a set of side-mounted snap-fit ​​slots 101. Each set of side-mounted snap-fit ​​slots 101 has a built-in anti-vibration rubber pad. The snap-fit ​​ear 7 cooperates with the side-mounted snap-fit ​​slot 101 to fix the entire side frame of the mounting housing 1. It also cooperates with the snap-fit ​​bracket 21 set on the rear protective housing 2 to fix the entire instrument cluster. The side-mounted snap-fit ​​slots 101 can reduce the negative impact of bumps generated during vehicle driving on the installation of the mounting housing 1 through the anti-vibration rubber pad.

[0029] Moisture-absorbing cotton blocks are fixed at the corners of the inner cavity of the mounting housing 1 to absorb moisture inside the instrument combination and reduce the negative impact of moisture on electrical components.

[0030] The front panel of the transparent cover 61 is provided with an anti-glare coating, and the outer end of the anti-glare coating is provided with an anti-static coating. The anti-glare coating can reduce the light reflection of the transparent cover 61, reduce glare and reflected light interference, improve visual comfort and clarity, protect eyesight, and enhance screen readability. The anti-static coating can reduce the static electricity adsorption of the transparent cover 61 and reduce the accumulation of dust on the transparent cover 61.

[0031] See Figure 3The rear protective housing 2 has several air outlets 12 evenly distributed on its top. An air inlet filter 15 is embedded in the center of the rear protective housing 2. The rear protective housing 2 is located at the rear end of the mounting housing 1, and its internal space communicates with the inner cavity of the mounting housing 1. A DC fan is installed at the front end of the air inlet filter 15. During vehicle operation, the DC fan draws air in from the air inlet filter 15, and the air circulates within the rear protective housing 2 and the inner cavity of the mounting housing 1, finally exiting from each air outlet 12. This circulating airflow effectively dissipates heat from the electrical components of the instrument cluster. The system is designed to handle dust accumulation on the air intake filter 15. A lower frame 17 is located below the air intake filter 15. Lifting slots are located on the left and right sides of the rear protective housing 2, corresponding to the lower frame 17. During long-term operation of the instrument cluster, dust accumulates on the air intake filter 15, affecting airflow cooling efficiency. The lower frame 17 provides space for the dust removal brush 16, and the lifting mechanism within the lifting slots controls the lifting of the dust removal brush 16. This controls the dust removal brush 16 to remove dust from the air intake filter 15, ensuring the multiple holes on the air intake filter 15 can function normally.

[0032] See Figure 5 Each set of lifting slots is equipped with a movable frame 26, and each movable frame 26 is equipped with a lifting screw 25. Each lifting screw 25 is equipped with a fixed mounting plate 22 on its top, and each fixed mounting plate 22 is equipped with a micro motor 23. Each lifting screw 25 is equipped with a guide rod 24 on its outer side. A dust removal brush plate 16 is provided between the two sets of movable frames 26. The upper end of the inner cavity of the rear protective shell 2 is used to install the two sets of fixed mounting plates 22. The two sets of fixed mounting plates 22 are used to fix the micro motors 23 and guide rods 24 to their respective micro motors 23 and guide rods 24. The lifting limit control of each movable frame 26 is established in the two sets of lifting slots. The two sets of micro motors 23 start working at the same time, causing the two sets of lifting screws 25 to rotate at the same frequency. The spiral threads at the connection of the two sets of movable frames 26 are respectively aligned with the threads of the two sets of lifting screws 25. That is, the two sets of movable frames 26 move up and down in the same direction along the guide rod 24, driving the dust removal brush plate 16 to remove dust from the air inlet filter 15.

[0033] See Figure 4The rear protective housing 2 has a set of installation limiting cavities 18 at its top outer end. Each installation limiting cavity 18 is equipped with a high-strength telescopic spring 19. Each high-strength telescopic spring 19 has a connecting bracket 20 at its outer end. Each connecting bracket 20 has a plug-in bracket 21 at its rear edge. Each plug-in bracket 21 has multiple sets of positioning screw holes. The installation limiting cavities 18 at the top outer end of the rear protective housing 2 establish a limiting installation for the high-strength telescopic spring 19 and the connecting bracket 20. When the instrument cluster is in the installation state, the high-strength telescopic spring 19 is in the relaxed state, supporting the plug-in bracket 21 to extend into the corresponding installation position. The installation structure is established through the positioning screw holes and connecting bolts. When it is necessary to disconnect the connection of the connecting bracket 20, the connecting bolts are removed, the connection between the plug-in bracket 21 and the installation position is disconnected, the connecting bracket 20 is pushed inward, the high-strength telescopic spring 19 is compressed, and the connection between the rear protective housing 2 and the installation position is disconnected. The connecting bracket 20 is designed as an irregular block structure, which is embedded in the corresponding position to enhance the structural strength of the connection between the instrument cluster and the vehicle.

[0034] An external heat sink 14 is provided above the air intake filter 15. An electrical connector 13 is provided on the left and right sides of the external heat sink 14. The external heat sink 14 establishes a connection with the electrical components, which can directly conduct the heat generated by the electrical components. In conjunction with the circulating airflow, it improves the heat dissipation efficiency of the instrument cluster. The electrical connector 13 establishes the electrical connection between the vehicle and the various electrical components of the instrument cluster, improving its disassembly and assembly efficiency.

[0035] The present invention provides an automotive instrument cluster with anti-glare protection, which establishes a fixed connection with the vehicle through multiple sets of plug ears 7, two sets of side-mounted slots 101 and two sets of plug brackets 21. A front-mounted extended sunshade 3 and two sets of side-mounted sunshades are set inside the instrument cluster for physical glare protection, and a convex lens 64 is used to focus the light on the instrument icons. An anti-glare coating is used to reduce glare and reflected light interference, improve visual comfort and clarity, protect eyesight, and enhance screen readability, thus achieving an anti-glare design for the instrument cluster.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto.
