Description

Technical Field

[0001] The utility model relates to the technical field of head-up displays, and in particular to a head-up display base, a head-up display and a vehicle. Background Art

[0002] Head-up display (HUD) technology was originally used in military aircraft to reduce the distraction of pilots' vision when viewing dashboard information. With the development of technology, HUD systems have been widely used in civilian cars to improve driving safety and comfort. Traditional HUD systems usually consist of multiple components, including projection units, reflectors, display screens, control units, etc. These components usually need to be installed separately, which increases the complexity and cost of assembly.

[0003] Traditional HUD bases are usually composed of multiple separate parts, requiring a complex assembly process, which not only increases manufacturing costs, but may also lead to errors during installation. Separate parts may become loose during long-term use, affecting the stability and display quality of the HUD. As the integration of electronic components increases, heat dissipation becomes a challenge, especially in a compact base space. Utility Model Content

[0004] The utility model aims to provide a head-up display base, a head-up display and a vehicle which have simple and stable structure, good installation accuracy and heat dissipation effect.

[0005] A head-up display base includes a cavity structure and a positioning protrusion structure, wherein the positioning protrusion structures are arranged at both ends of the cavity structure, and the cavity structure and the positioning protrusion structure are integrally formed. The cavity structure includes a recessed portion and a mounting portion, a light-through port is provided at the bottom of the recessed portion, and the mounting portion is used to mount a secondary reflector assembly. A side wall of the cavity structure is provided with a plurality of heat dissipation fins, and an mounting groove is provided on the outside of one side wall of the cavity structure, and the mounting groove is used to mount a PCB assembly.

[0006] In the above scheme, the cavity structure and the positioning protrusion structure are formed in one piece, which simplifies the assembly process, thereby improving the stability of the head-up display base. The cavity structure integrates the mounting portion of the secondary reflector assembly and the mounting slot of the PCB assembly, reducing the need for additional components and simplifying the internal layout. A light opening is set at the bottom of the recessed portion of the cavity structure to provide the necessary light channel for the projection unit. The design of the positioning protrusion structure can improve the accuracy and stability of the installation. The multiple heat dissipation fins set on the side wall of the cavity structure take into account the heat dissipation requirements of the internal electronic components, thereby improving the service life of the electronic components inside the cavity.

[0007] Furthermore, the positioning protrusion structure includes a positioning plate connected to the cavity structure, side reinforcing ribs connected to the cavity structure are provided on both sides of the positioning plate, and a middle reinforcing rib connected to the cavity structure is provided in the middle of the positioning plate.

[0008] In the above scheme, the overall stability of the HUD base can be significantly improved by connecting the positioning plate to the cavity structure and setting the side reinforcement ribs and the middle reinforcement ribs. The reinforcement ribs serve as structural supports and can withstand greater mechanical stress, reduce deformation and vibration during use, and thus simplify the assembly process of the head-up display, because the positioning protrusion structure provides a clear installation point and direction, reducing the adjustment and alignment work during assembly.

[0009] Furthermore, the positioning plate is provided with at least two positioning holes.

[0010] In the above scheme, the positioning holes allow the head-up display base to be accurately fixed in the vehicle using bolts or other fasteners, and the head-up display base can be quickly aligned and installed with the vehicle's fixing points, reducing installation time and potential errors, thereby ensuring the head-up display effect.

[0011] Furthermore, a connecting groove is provided at the bottom of the recessed portion, and a plurality of connecting holes are provided on the connecting groove.

[0012] In the above scheme, the connecting groove is used to connect with a projection unit such as a TFT display screen, and bolts or other fasteners are passed through the connecting hole to connect the projection unit and the bottom of the recessed portion, thereby connecting the projection unit and the head-up display base. The design of the connecting groove and the connecting hole enables the projection unit to be accurately aligned with the head-up display base, ensuring the correct position and clarity of the projected image.

[0013] Furthermore, the mounting portion is provided with a plurality of grooves, and a plurality of mounting holes are provided around the plurality of grooves.

[0014] In the above scheme, the design of the grooves and mounting holes enables the secondary mirror assembly to be stably installed in the head-up display base, reducing the displacement or shaking of the mirror caused by vibration during vehicle driving. The design of the grooves and mounting holes simplifies the assembly process of the mirror assembly because they provide clear fixing points and reduce the adjustment work during assembly.

[0015] Furthermore, a plurality of positioning grooves are provided inside a side wall of the cavity structure away from the mounting groove.

[0016] In the above scheme, the positioning groove can reduce the displacement of the secondary reflector in the secondary reflector assembly due to vehicle vibration or rapid change of direction. Since the secondary reflector assembly will adjust the angle according to the projection position, the positioning groove can ensure that the secondary reflector assembly will not have a large offset when adjusting the angle, thereby ensuring the accuracy and display quality of the reflected image.

[0017] Furthermore, the cavity structure and the positioning protrusion structure are injection molded using high-strength plastic material.

[0018] In the above solution, high-strength plastics are usually lighter than metal materials, which helps to reduce the overall weight of the head-up display and has a positive impact on the vehicle's energy efficiency and dynamic performance. Injection molding realizes the integrated design of the head-up display base, reduces the number of assembly parts, and simplifies the assembly process.

[0019] A head-up display comprises a head-up display base as described in any one of the above solutions.

[0020] In the above solution, the design and function of the head-up display base simplifies the assembly process of the head-up display, improves assembly efficiency and reduces assembly costs. The precise projection and stable display effect enhance the driver's experience and make information reading more intuitive and comfortable.

[0021] A vehicle comprises a head-up display as described in the above solution.

[0022] The utility model provides a head-up display base, a head-up display, and a vehicle with a simple and stable structure, good installation accuracy, and a beneficial effect of heat dissipation. The cavity structure and the positioning protrusion structure are integrally formed, which simplifies the assembly process, thereby improving the stability of the head-up display base. The cavity structure integrates the mounting portion of the secondary reflector assembly and the mounting slot of the PCB assembly, reducing the need for additional components and simplifying the internal layout. A light opening is provided at the bottom of the recessed portion of the cavity structure to provide the necessary light channel for the projection unit. The design of the positioning protrusion structure can improve the accuracy and stability of the installation, and the multiple heat dissipation fins provided on the side wall of the cavity structure take into account the heat dissipation requirements of the internal electronic components, thereby improving the service life of the electronic components inside the cavity.
