Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a steering support assembly and a vehicle. Background Art

[0002] New energy vehicles, with their innovative battery drive technology, have shown significant advantages in environmental protection and energy saving. However, their cruising range is limited by battery capacity and vehicle weight. Therefore, under the condition of a certain battery capacity, reducing the weight of the vehicle has become a key strategy to increase the cruising range of new energy vehicles.

[0003] At present, the automotive steering support system generally adopts steel materials, which is based on its advantages of low cost and stable performance. However, the weight of steel steering support is relatively heavy, which poses a challenge to the weight control of new energy vehicles, thus affecting their range. At the same time, the heavier steering support also brings certain restrictions to the arrangement of parts inside the dashboard, affecting the flexibility and efficiency of the vehicle design. In addition, the welding process of steel steering support limits its ability to adapt to different models. Due to the differences in design and structure of different models, it is difficult for a universal steel steering support to meet the needs of all models, thereby increasing production costs and manufacturing complexity.

[0004] CN218400733U discloses a steering support modular structure, including a steering support body and a steering column, the steering support body is arranged on the top of the steering column, a sheet metal bracket assembly is arranged between the steering support body and the steering column, the sheet metal bracket assembly includes a steering column mounting bracket and a steering support body connecting bracket, and the steering column mounting bracket and the steering support body connecting bracket are fixedly connected. Its purpose is to solve the problem that the integrated magnesium alloy steering support cannot match the installation requirements of the steering column at different positions on the same platform, and the development cycle, development cost and development difficulty have not been effectively improved. However, the crossbeam of the steering support modular structure still uses traditional steel round tubes, which is not only difficult to meet the requirements of lightweight design, but also causes the connection method between the bracket and the cross tube to only use welding technology. Today, with the continuous improvement of automobile intelligence, the installation positions of the central control screen and electrical parts of different models are different. Therefore, the traditional steel cross tube is difficult to meet the installation requirements of the central control screen and electrical parts of different models. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A steering support assembly comprises a crossbeam, wherein the crossbeam comprises a steel portion and a plastic portion, and the steel portion and the plastic portion are integrally formed.

[0008] According to the above technical means, the crossbeam structure is made of steel and plastic parts in one piece.

This solves the problem that the traditional steering support assembly is heavy and difficult to meet the lightweight requirements of automobiles.

[0009] Preferably, at least two groups of first mounting holes are provided near the middle along the length direction of the beam.

[0010] By setting at least two groups of first mounting holes on the crossbeam, the corresponding bracket structure can be assembled according to the peripheral parts of the steering support assembly of different models, which effectively improves the versatility of the steering support assembly, eliminates the need for adapters, and further reduces production costs and development cycles.

In addition, the remaining first mounting holes can also be used for the assembly of central control screens of other models.

[0014] Preferably, at least two groups of second mounting holes are provided near the end along the length direction of the beam.

[0015] By setting at least two groups of second mounting holes on the crossbeam, the corresponding bracket structure can be assembled according to the peripheral parts of the steering support assembly of different models, which effectively improves the versatility of the steering support assembly, eliminates the need for adapters, and further reduces production costs and development cycles.

In addition, the remaining second mounting holes can also be used for the assembly of other types of electrical components.

[0018] Preferably, the cross section of the steel portion of the beam along the width direction is C-shaped.

[0024] Preferably, the plastic parts of the cross beams have different thicknesses.

[0025] By setting the thickness of the plastic part of the crossbeam to be different, the wall thickness of the part that needs to be strengthened is increased, which not only meets the rigidity requirements of the local part, but also effectively achieves the goal of lightweighting.

DETAILED DESCRIPTION

[0041] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated. Example

[0043] like Figures 1 to 6 As shown, a steering support assembly includes a cross beam 1, and the cross beam 1 includes a steel portion 11 and a plastic portion 12, and the steel portion 11 and the plastic portion 12 are integrally formed.

[0044] By using a steel part and a plastic part to form a crossbeam structure in one piece, plastic is lighter than steel, thus effectively achieving the lightweight goal while meeting the strength requirements.

[0045] Among them, the specific setting method of the crossbeam 1 is to use higher-strength steel materials, such as high-strength steel plates, in the main load-bearing area; and use lightweight materials, such as plastics, in the non-main load-bearing area. This can effectively ensure the strength of the crossbeam and the structural and functional integrity of the crossbeam.

[0046] In some embodiments, in order to assemble the corresponding bracket structure according to the peripheral parts of the steering support assembly of different models to improve the versatility of the steering support assembly, at least two groups of first mounting holes 13 are set near the middle along the length direction of the crossbeam 1. Such a design can effectively save the setting of the adapter when assembling the brackets of the peripheral parts in the subsequent process, further reducing the production cost and development cycle.

[0047] In some embodiments, all the first mounting holes 13 are arranged at intervals along the length direction of the beam 1 .

[0048] For example, the crossbeam 1 is assembled and fixed to the first central control screen mounting bracket 2 through one group of first mounting holes 13, and the crossbeam 1 is assembled and fixed to the second central control screen mounting bracket 3 through the remaining group of first mounting holes 13. In this way, the assembly of central control screen brackets of different models is effectively realized, and the platform versatility of the steering support assembly is improved.

[0049] In some embodiments, in order to assemble the corresponding bracket structure according to the peripheral parts of the steering support assembly of different models to improve the versatility of the steering support assembly, at least two groups of second mounting holes 14 are set near the end along the length direction of the crossbeam 1. Such a design can effectively save the setting of the adapter when assembling the brackets of the peripheral parts in the subsequent process, further reducing the production cost and development cycle.

[0050] In some embodiments, all the second mounting holes 14 are arranged at intervals along the length direction of the beam 1 .

[0051] For example, the cross beam 1 is assembled and fixed to the first electrical component mounting bracket 4 through one group of the second mounting holes 14, and the cross beam 1 is assembled and fixed to the second electrical component mounting bracket 5 through the remaining group of the second mounting holes 14. In this way, the assembly of electrical component brackets of different models is effectively realized, and the platform universality of the steering support assembly is effectively realized.

[0052] The first electrical component 8 is mounted on the first electrical component mounting bracket 4 , and the second electrical component 9 is mounted on the second electrical component mounting bracket 5 .

[0053] In some embodiments, the cross section of the steel portion 11 of the beam 1 along the width direction is C-shaped.

[0054] For example, the steel portion 11 of the cross beam 1 is formed by stamping an ultra-deep-drawn hot-dip galvanized steel plate, and the wall thickness of the steel portion 11 is 1.2 mm to 1.5 mm. The wall thickness of a conventional steel round tube is usually between 1.5 mm and 2.0 mm. Therefore, the steering support assembly in this embodiment is significantly lighter than the conventional steering support assembly, achieving the goal of lightweighting.

[0055] Exemplarily, spare holes for mounting brackets are provided on the crossbeam 1, and bolts or nuts are pre-embedded in all mounting holes on the crossbeam 1 to improve assembly efficiency and assembly accuracy.

[0056] In addition, the steel portion 11 and the plastic portion 12 of the cross beam 1 are integrally injection molded, so that the mounting holes on the cross beam 1 provide flow channels for injection molding, and the mounting holes achieve the effect of weight reduction.

[0057] In some embodiments, the plastic part 12 is wrapped on the outer side of the opening of the steel part 11, so that the C-shaped steel part 11 is embedded in the plastic part 12 as an insert, and the bracket is connected by screwing on the outer side of the opening of the steel part 11, thereby avoiding the problems of large welding deformation and poor precision caused by the welding process of traditional steel steering supports.

[0058] In some embodiments, in order to simultaneously meet local rigidity requirements and lightweight goals, the wall thickness of the plastic portion 12 of the beam 1 is set to be different, so that the wall thickness of the portion that needs to be strengthened can be increased according to actual needs.

[0059] In some embodiments, in order to ensure the overall firmness of the cross beam, the steel portion 11 and the plastic portion 12 are integrally formed using an injection molding process.

[0060] In some embodiments, in order to reduce weight and processing cost at the same time, the plastic part 12 is made of at least one of glass fiber reinforced polypropylene, glass fiber reinforced polyamide and glass fiber reinforced nylon.

[0061] Exemplarily, the material of the plastic part 12 is PP+GF60 (60% glass fiber reinforced polypropylene), PA+GF60 (60% glass fiber reinforced polyamide) or PA+CF (glass fiber reinforced nylon).

[0062] In some embodiments, at least an air conditioner mounting bracket 6 and a HUD mounting bracket 7 are also provided on the crossbeam 1 .

[0063] Exemplarily, the cross beam 1 also has at least a steering column mounting bracket, a PAB mounting bracket and a glove box mounting bracket.

[0064] For example, in order to facilitate disassembly and maintenance, the central control screen mounting bracket, the electrical parts mounting bracket, the air conditioning mounting bracket 6, the HUD mounting bracket 7, the steering column mounting bracket, the PAB mounting bracket and the glove box mounting bracket are all assembled and fixed to the crossbeam 1 by bolts.

[0065] For example, the central control screen mounting bracket, electrical parts mounting bracket, air conditioning mounting bracket 6, HUD mounting bracket 7, steering column mounting bracket, PAB mounting bracket and glove box mounting bracket can be produced using a variety of processes, including but not limited to traditional steel brackets, magnesium alloy die-cast brackets and injection molded brackets, etc., so that brackets of different materials can be selected according to the needs of different vehicle models, further improving the versatility and flexibility of the brackets, thereby reducing the weight and cost of the steering support assembly.

[0066] In some embodiments, a vehicle is also provided, comprising the steering support assembly in any of the above embodiments.

[0067] In summary, the steering support assembly of the utility model adopts a steel part and a plastic part to form a crossbeam structure. Plastic is lighter than steel, thereby effectively achieving the lightweight goal and meeting the strength requirements. It solves the problem that the traditional steering support assembly is heavy and difficult to meet the lightweight requirements of automobiles. It has the advantage of a simple structure and has the value of promotion and application in the field of automobile parts technology.

[0068] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
