[0052] On the basis of the above embodiments, variant embodiments of the above embodiments are proposed. Here, it should be noted that for the sake of brief description, only the differences from the above embodiments are described in the variant embodiments.

[0057] The welding surfaces are used to fix the left end of the steering support left mounting bracket and the arc steering support left crossbeam assembly by carbon dioxide shielded welding.

[0058] In practical applications, carbon dioxide shielded welding, also known as carbon dioxide gas shielded arc welding, with carbon dioxide (sometimes a mixed gas of CO2+Ar) as the shielding gas, is mainly used for manual welding. Due to the special influence of the thermal physical properties of carbon dioxide gas, when using a conventional welding power source, it is impossible for the molten metal at the end of the welding wire to form a balanced axial free transition. Usually, short circuit and droplet necking explosion are required, and a very stable welding process can be obtained, reducing spatter to a minimum. Since the shielding gas used is inexpensive, the weld formation is good when using short circuit transition, and a high-quality welded joint without internal defects can be obtained by using a welding wire containing a deoxidizer. Therefore, this welding method has become one of the most important welding methods for ferrous metal materials. Due to the high current density of CO2 gas shielded welding, up to 100-300 A / mm2, the arc heat is concentrated, the melting efficiency of the welding wire is high, the penetration thickness of the base metal is large, the welding speed is fast, and there is no need for slag cleaning after welding, so the efficiency can be significantly improved, saving electric energy. At the same time, due to the low price of CO2 gas and the welding wire, the requirements for production preparation before welding are not high, and the working hours for post-welding cleaning and correction are few, so the cost is low.

[0072] In an optional embodiment of the present invention, the vehicle is configured with a steering column;

[0073] The annular steering support HUD mounting bracket is provided with a steering column mounting point;

[0074] The steering column mounting point is used to mount the steering column.

[0075] In practical applications, the steering column is an element that connects the steering wheel and the steering gear in the steering system. Through the steering column, the driver transmits torque to the steering gear, driving the steering gear to achieve steering. Common steering columns include hydraulic power steering columns, electro-hydraulic power steering columns, and electric power steering columns. Different steering column systems are different, and the steering column is assembled in the vehicle.

[0076] In a specific implementation, the vehicle in the embodiment of the present invention is configured with a steering column 4; the annular steering support HUD mounting bracket 22 is provided with a steering column mounting point 222; the steering column mounting point 222 is used to mount the steering column 4.

[0078] In an optional embodiment of the present invention, the annular steering support HUD mounting bracket 22 is a magnesium alloy die-cast part.

[0079] In practical applications, magnesium alloy is an alloy composed of magnesium and other metals, and is the lightest known structural metal material at present. Its density is only one-fourth of that of steel and two-thirds of that of aluminum. Due to its light weight, high strength, heat resistance, corrosion resistance and other characteristics, magnesium alloy is widely used in the fields of aerospace, electronic communication, medical equipment, etc. In recent years, with the increasing demand for vehicle lightweighting, magnesium alloy has also shown great potential and prospects in the automotive industry. As a lightweight material, magnesium alloy has the advantages of significant weight reduction effect, excellent earthquake resistance and noise reduction, and good die-casting performance. Compared with steel and aluminum alloy, magnesium alloy has a lower density, which is one-fourth of steel and two-thirds of aluminum alloy respectively. Therefore, when maintaining the same volume, automotive parts made of magnesium alloy can achieve a weight reduction of 25%-75%. In addition, magnesium alloy has a low elastic modulus and a high attenuation coefficient, which can effectively absorb and dissipate vibration and noise, improving the comfort and safety of the vehicle. Magnesium alloy also has good die-casting performance, and can manufacture complex shapes and structures, reducing subsequent processing and assembly links, lowering production costs and time. Among them, most of the magnesium alloy parts for vehicles are die-castings, mainly used in parts such as shells and brackets. Die-casting is a process of injecting molten metal material into a mold and rapidly solidifying and forming under high pressure, which has the advantages of high production efficiency, high product precision, and good surface quality.

[0080] In a specific implementation, the annular steering support HUD mounting bracket 22 in the embodiment of the present invention can be a magnesium alloy die-cast part.

[0081] In the embodiment of the present invention, by making the annular steering support HUD mounting bracket a magnesium alloy die-cast part, the installation accuracy for the head-up display is improved, and further the production cost of the part is reduced.

[0082] In an optional embodiment of the present invention, the left mounting bracket of the steering support is a sheet metal stamping and welding part; the right cross tube assembly of the steering support is a sheet metal stamping and welding part.

[0083] In practical applications, sheet metal stamping technology, also known as sheet metal stamping and welding, is achieved by stamping hot-rolled or cold-rolled steel sheets into the shapes required for manufacturing parts. This technology allows the simultaneous production of a large number of components. Sheet metal stamping is a low-cost manufacturing technology. Its cost is usually lower than other methods because sheet metal stamping does not require dies or tools to create parts. Sheet metal stamping can produce thousands of identical parts at a time, so a large number of products can be effectively manufactured while maintaining quality standards. It is suitable for parts with simple shapes and no large-scale customization, and most of the tools for sheet metal stamping are simple to operate and have a low learning threshold, and can manufacture parts of various shapes and sizes. Therefore, using sheet metal stamping and welding parts as the left mounting bracket 23 of the steering support and the right cross tube assembly 24 of the steering support can effectively improve production efficiency and reduce costs.

[0084] In a specific implementation, the left mounting bracket 23 of the steering support in the embodiment of the present invention can be a sheet metal stamping and welding part; the right cross tube assembly 24 of the steering support can be a sheet metal stamping and welding part.

[0085] In the embodiment of the present invention, by making the left mounting bracket of the steering support a sheet metal stamping and welding part; the right cross tube assembly of the steering support a sheet metal stamping and welding part, the production cost of the installation structure for the head-up display is further reduced.

[0086] In an optional embodiment of the present invention, the right end of the left beam assembly of the arc-shaped steering support is fixed to the right cross tube assembly of the steering support by welding.

[0087] In practical applications, welding is a metal processing technology that melts metal materials through the conduction of heat energy and fuses them with other metal materials. One of the greatest advantages of welding is its ability to improve the stability of connections. Compared with other connection methods, welding can form a larger contact area on the connection surface, thus having better firmness and seismic resistance. Welded connections will not become loose due to heavy loads, vibrations, or temperature changes, effectively enhancing the structural strength and stability of workpieces. In addition, welding can not only improve the stability of connections but also enhance the sealing performance. During the welding process, the molten metal fills the gaps and micro-pores in the connection area, forming a continuous metal connection. This metal connection can prevent the penetration of gases, liquids, and solids, ensuring the normal operation of workpieces. Welded connections have good sealing performance, which can meet some special working environments or equipment that require sealing. At the same time, welding can achieve efficient electrical and thermal conductivity between metals. During the welding process, the metal materials melt and fuse together at high temperatures, forming a continuous metal conductor. This conductor can effectively conduct current and heat, improving the electrical and thermal conductivity of the connection area. Welded connections are widely used in electronic and electrical equipment, the automotive industry, and the energy field, ensuring the normal operation of equipment and efficient energy transmission. Moreover, welded connections have good appearance quality and a certain degree of aesthetics. The welded joints can be made flush with the workpiece surface, and the shapes of the welded joints are diverse, meeting the requirements of different structures and shapes. Welding can also repair and improve the surface of workpieces, improving the surface quality and flatness of metal workpieces and enhancing the overall appearance quality of workpieces. The appearance quality of welded connections is crucial for some products and equipment with high aesthetic requirements. It can be seen that welding, as a metal processing technology, has multiple advantages. Welding can improve the stability and sealing performance of connections, while also enhancing the electrical and thermal conductivity of connections. In addition, welding can also improve the appearance quality and aesthetics of the connection area. These advantages make welding widely used in various industries and an indispensable part of modern engineering fields.

[0088] In a specific implementation, the right end of the arc-shaped steering support left crossbeam assembly 21 in the embodiment of the present invention and the steering support right cross-tube assembly 24 can be fixed by welding.

[0089] In the embodiment of the present invention, by fixing the right end of the arc-shaped steering support left crossbeam assembly and the steering support right cross-tube assembly by welding, the connection stability of the installation structure for the head-up display is further improved.

[0090] To enable those skilled in the art to better understand the embodiments of the present invention, the following uses an example to illustrate the embodiments of the present invention.

[0091] Use a sheet metal stamping part as the arc-shaped steering support left crossbeam assembly 21 to achieve the installation of the head-up display 3. For example, the head-up display 3 can be an AR-HUD head-up display. The annular steering support HUD mounting bracket 22 provides mounting points for the steering column 4 and the head-up display 3. The annular steering support HUD mounting bracket 22 is fixedly connected to the arc-shaped steering support left crossbeam assembly 21 by bolts 26. The arc-shaped steering support left crossbeam assembly 21 is a part of the main beam of the steering support 2. Its left side is fixedly connected to the steering support left mounting bracket 23 by means of carbon dioxide shielded welding, and its right side is fixedly connected to the steering support right cross tube assembly 24 by welding to form a rigid integral structure. This structure is fixed on the white body 1 by bolts to achieve the position fixation of the head-up display 3 inside the vehicle, and further, the vehicle head-up display function can be realized through the cooperation of other systems.

[0092] The annular steering support HUD mounting bracket 22 can be a magnesium alloy die-cast part. Its structure is roughly annular. There are 2 convex table surfaces 221 on the upper half, which provide mounting points for the head-up display 3. The convex table surfaces 221 can be machined by a machine tool to effectively control the accuracy of their mounting surfaces. There are 2 support feet on the lower half, and steering column mounting points 222 can be set on the support feet. The steering column mounting points 222 provide mounting points for the steering column 4. Since the magnesium alloy die-cast part can adapt to different vehicle models and be compatible with the installation of different models of head-up displays 3, the adaptability of this structure is very strong.

[0093] The arc-shaped steering support left crossbeam assembly 21 is a sheet metal stamping and welding part. Its structure is roughly bow-shaped. It is welded to the steering support left mounting bracket 23 on the left side and to the steering support right cross tube assembly 24 on the right side to form an integral body, providing mounting points for the steering column 4 and the AR-HUD head-up display 3. The arc-shaped steering support left crossbeam assembly 21 can be a stamping and welding part, which can achieve bending to different degrees, so its adaptability is stronger.

[0094] The steering support left mounting bracket 23 is a sheet metal stamping and welding part, shaped like an L. There can be 4 bracket mounting points 231 on the left side to provide mounting points for the steering support 2, and a welding surface 232 is designed on the right side of the bracket to provide a welding bearing surface for the arc-shaped steering support left crossbeam assembly 21.

[0095] The steering support right cross tube assembly 24 is a sheet metal stamping and welding part. By welding it to the arc-shaped steering support left crossbeam assembly 21, the steering support 2 forms an integral body.

[0096] The head-up display 3 is a box-shaped injection-molded part, fixed on the annular steering support HUD mounting bracket 22 by 4 cross-recessed head bolts 31, providing an information source for the head-up display technology.

[0097] A sheet metal stamping part can be used as the arc-shaped steering support left crossbeam assembly 21 to provide more space for the layout of the head-up display 3. The annular steering support HUD mounting bracket 22 is formed by die-casting magnesium alloy, which can not only solve complex forming problems, but also meet the space layout of the head-up display 3 and the steering column 4. It has strong structural adaptability, high precision and low cost.

[0098] CO2 shielded arc welding is one of the important welding processes for ferrous metal parts. By generating a large current through the short circuit of the power supply, the deoxidized welding wire between the two parts to be welded melts instantaneously to form a firm joint. Due to the special influence of the thermal physical properties of CO2 gas, a high-quality welded joint without internal defects can be formed, so it is called CO2 shielded arc welding.

[0099] The arc-shaped steering support left crossbeam assembly 21 is composed of a steering support left crossbeam 211, a first steering support left crossbeam reinforcement 212, a second steering support left crossbeam reinforcement 213 and a steering support left crossbeam lower mounting bracket 214. Among them, the first steering support left crossbeam reinforcement 212 and the second steering support left crossbeam reinforcement 213 are welded to the steering support left crossbeam 211 by CO2 shielded arc welding to form a box part with a cavity, which can not only strengthen the crossbeam but also provide two mounting points on the left and right for the annular steering support HUD mounting bracket 22. The steering support left crossbeam lower mounting bracket 214 is welded to the steering support left crossbeam 211 by CO2 shielded arc welding to provide a lower mounting point for the annular steering support HUD mounting bracket 22. The installation and connection of the three points can effectively strengthen the stability of this structure.

[0100] The steering support left mounting bracket 23 is a sheet metal stamping and welding part, and it has 4 bracket mounting points 231 for mounting and fixing with the body-in-white 1. Its welding surface 232 is used for welding the arc-shaped steering support left crossbeam assembly 21 by CO2 shielded arc welding.

[0101] The steering support right cross tube assembly 24 is a sheet metal stamping and welding part assembly, which is a welded assembly structure formed by welding several metal brackets on a steel pipe beam structure through CO2 shielded arc welding. It is welded to the arc-shaped steering support left crossbeam assembly 21 by CO2 shielded arc welding on the left side to form an integral steering support 2 structure.

[0102] This embodiment also proposes a head-up display, and the head-up display is provided with an adapter structure adapted to the above-mentioned mounting structure.

[0103] This embodiment also proposes a vehicle, and the vehicle includes a vehicle body, and the above-mentioned mounting structure is provided on the vehicle body.
