[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In the claims, specification and the above drawings of the present utility model, the terms "up" and "down" are the same as the up-down direction of the vehicle body, the terms "front" and "rear" are the same as the front-rear direction of the vehicle body, and the terms "left" and "right" are the same as the left-right direction of the vehicle body. The remaining directional words, unless otherwise clearly defined, such as the use of terms such as "length" and "width" to indicate direction or positional relationship are based on the direction and positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, so they cannot be understood as limiting the specific protection scope of the present invention.

[0029] Since the left and right ends of the instrument panel cross beam assembly are connected to the A-pillar respectively, and the connection position of the instrument panel cross beam assembly and the A-pillar has a large drop in the right transition area, there is a problem of insufficient rigidity of the instrument panel cross beam, which causes the instrument panel cross beam to bend and deform during a small overlap side collision of the car. Under the same impact force, the instrument panel cross beam absorbs less impact energy, and the impact energy transmitted to the A-pillar increases, which increases the intrusion of the A-pillar into the car's cab, causing adverse effects on the driving safety of the car. Therefore, the utility model provides a reinforcing structure for the instrument panel cross beam, which solves the above problem by adding a reinforcing plate in the transition area where the instrument panel cross beam assembly and the A-pillar have a large drop.

[0030] Please also read Figures 1 to 5 The instrument panel cross beam reinforcement structure provided by the utility model is now described. The instrument panel cross beam reinforcement structure includes an instrument panel cross beam assembly 1 and a reinforcement plate 2. The instrument panel cross beam assembly 1 includes an instrument panel cross beam body 11 and an A-pillar connecting frame 12 at its end; the reinforcement plate 2 is fixed between the instrument panel cross beam body 11 and the A-pillar connecting frame 12; the reinforcement plate 2 and the instrument panel cross beam body 11 form a closed-loop force transmission channel.

[0031] The instrument panel cross beam reinforcement structure provided by the utility model is provided with a reinforcement plate 2 in the weak area where the instrument panel cross beam assembly 1 is connected to the A-pillar, which can improve the rigidity of this area and improve the deformation resistance of the instrument panel cross beam assembly 1, so as to avoid bending and deformation of the instrument panel cross beam during a small overlap side collision of the vehicle, thereby reducing the adverse effects on the driver and passengers; at the same time, the reinforcement plate 2 is fixedly connected to the instrument panel cross beam body 11 to form a closed-loop force transmission channel. When the vehicle is subjected to a side collision, the formed closed-loop force transmission channel can effectively absorb and disperse the impact energy, thereby effectively reducing the intrusion of the A-pillar into the vehicle's cab and improving the safety factor of the driver and passengers.

[0032] It should be noted that the reinforcement structure provided in the present embodiment in which the reinforcement plate 2 is arranged in the transition area where the dashboard cross beam assembly 1 is connected to the A-pillar, can be arranged only in the area where the right end of the dashboard cross beam assembly 1 is connected to the right A-pillar, or can be arranged in the connection area of ​​the left A-pillar. Of course, the shape of the reinforcement plate 2 can be appropriately adjusted according to the structure of the left and right ends of the dashboard cross beam assembly 1.

[0033] In some embodiments, see Figure 2As shown, the upper and lower edges of the instrument panel cross beam body 11 are respectively provided with a first flange 111 extending to the front of the vehicle body, and the reinforcing plate 2 is supported on the first flange 111 to form a closed-loop force transmission channel, and the shape of the closed-loop force transmission channel is a quadrilateral structure. The closed-loop force transmission channel has the functions of improving the rigidity, force transmission and energy absorption of the instrument panel cross beam assembly 1. When the collision impact energy is transmitted to the instrument panel cross beam body 11, the ability to resist bending deformation can be improved due to the improvement of rigidity, and the impact energy can be mutually reduced along the closed-loop transmission. Therefore, the closed-loop force transmission can effectively attenuate the impact energy and absorb more impact energy, thereby effectively reducing the intrusion of the A-pillar into the vehicle cab and improving the driving safety factor.

[0034] The first flanges 111 above and below the instrument panel cross beam body 11 form a cavity or a box-like structure after the reinforcing plate 2 is connected to the instrument panel cross beam body 11, which has an energy-absorbing effect, thereby reducing the impact energy invading the cab.

[0035] In some embodiments, see Figures 2 to 5 The upper and lower edges of the reinforcing plate 2 are respectively provided with second flanges 21, and the two second flanges 21 extend toward the front and rear of the vehicle body respectively. The reinforcing plate 2 can improve its own structural rigidity by providing the second flanges 21, thereby improving the rigidity of the instrument panel cross beam assembly 1 and the ability to resist bending deformation in the transition area, thereby preventing the instrument panel cross beam assembly 1 from bending and deforming, which would adversely affect the safety of the occupants in the cab.

[0036] The two second flanges 21 extend forward and backward to form a Z-shaped structure (see Figure 5 ), when transmitting force, it can transfer the impact energy to different directions, thereby dispersing the impact force and protecting the safety of the occupants in the car.

[0037] Optionally, the upper and lower edges of the reinforcing plate 2 can be provided with a second flange 21 extending forward at the same time, or a second flange 21 extending backward at the same time, which has a reinforcing effect on the structure of the reinforcing plate 2 itself, thereby facilitating the improvement of the anti-deformation ability of the instrument panel crossbeam assembly 1 at the weak transition link connected to the A-pillar.

[0038] In some embodiments, see Figure 1 and Figure 4As shown, the reinforcing plate 2 has a fixed base 23 and a local enlarged portion 24, wherein the fixed base 23 is fixed to the instrument panel cross beam body 11, and the local enlarged portion 24 is fixed to the A-pillar connecting frame 12; the width of the local enlarged portion 24 along the vertical direction of the vehicle body is greater than the width of the fixed base 23. Since the A-pillar has a width extending along the vertical direction of the vehicle body, the width of the A-pillar connecting frame 12 in the vertical direction of the vehicle body when matched with the A-pillar is much greater than its length in the left-right direction of the vehicle body. Therefore, in order to increase the matching size with the A-pillar connecting frame 12 in the vertical direction of the vehicle body, the reinforcing plate 2 is designed to adopt the structure of the local enlarged portion 24, thereby improving the firmness of the connection between the reinforcing plate 2 and the A-pillar connecting frame 12.

[0039] The width of the fixing base 23 of the reinforcing plate 2 along the up-down direction of the vehicle body is conformed to the instrument panel cross beam body 11 , thereby improving the reliability of the connection with the instrument panel cross beam body 11 .

[0040] The reinforcing plate 2 has an overall T-shaped structure due to the structural shape of the local enlarged portion 24 and the fixed base 23. In terms of energy absorption and force transmission, it can disperse the impact force and improve the force transmission and energy absorption effects. Structurally, the part that cooperates with the A-pillar connecting frame 12 has a longer matching dimension in the up and down directions to ensure the reliability of the fixation with the A-pillar connecting frame 12; the part that cooperates with the instrument panel cross beam body 11 basically maintains the same width as the instrument panel cross beam body 11 in the up and down directions, and has a longer matching dimension in the length along the left and right directions, so that the firmness of the connection can be ensured while the overall shape of the instrument panel cross beam body 11 will not be affected in the up and down directions.

[0041] In some embodiments, see Figure 1 and Figure 4 As shown, the width of the fixed base 23 along the vertical direction of the vehicle body increases from the instrument panel cross beam body 11 to the A-pillar connecting frame 12. The reinforcing plate 2 can disperse the impact force and improve the effect of force transmission and energy absorption through the gradual change of the cross-sectional shape. Among them, the fixed base 23 of the reinforcing plate 2 is consistent with the width of the instrument panel cross beam body 11 in the vertical direction, avoiding affecting the appearance of the instrument panel cross beam body 11 and avoiding interference with other surrounding components.

[0042] In some embodiments, see Figure 1 and Figure 4 As shown, the reinforcing plate 2 is provided with reinforcing ribs 22 that penetrate the fixed base 23 and the local enlarged portion 24. By providing the reinforcing ribs 22 on the reinforcing plate 2, the structural strength of the reinforcing plate 2 itself is further improved, thereby improving the performance of the reinforcing plate 2 in anti-deformation during collision.

[0043] In some embodiments, see Figure 1 and Figure 4As shown, the width of the reinforcing rib 22 on the local enlarged portion 24 is greater than its width on the fixed base 23. This shape of the reinforcing rib 22 matches the structural shape of the reinforcing plate 2 and also forms a T-shaped structure, which is beneficial to improving the structural rigidity of the reinforcing plate 2 and dispersing the impact force and transmitting the force smoothly.

[0044] Optionally, the reinforcing rib 22 may be a strip-shaped structure extending in the up-down direction or the left-right direction of the vehicle body.

[0045] In combination with the above embodiments, the reinforcing plate 2 provided by the present invention improves the overall strength and rigidity of the dashboard crossbeam assembly 1 by optimizing the structural design such as shape, reinforcing ribs 22 and flanges, thereby enhancing the stability of the vehicle in a collision event.

[0046] In some embodiments, see Figure 1 and Figure 3 As shown, the dashboard cross beam body 11 and the A-pillar connecting frame 12 are both provided with mounting posts 112 protruding backwards, and the reinforcing plate 2 is mounted on the mounting posts 112 by means of fasteners 4. The reinforcing plate 2 and the dashboard cross beam body 11 need to be assembled and fixed together, and the fasteners 4 are used for fixing, which is simple and convenient to assemble, and will not cause welding deformation compared to welding.

[0047] The fastener 4 can be a bolt, a snap or a riveted fastener, preferably a bolt fastener. At this time, the mounting post 112 integrally formed on the instrument panel cross beam assembly 1 can be directly provided with an internal threaded hole, so that a through hole 25 can be drilled on the reinforcing plate 2, and the reinforcing plate 2 is fixed to the mounting post 112 by bolts, which is simple and convenient to install and disassemble, and will not cause stress deformation at the installation position.

[0048] The mounting column 112 has the function of supporting the reinforcing plate 2 and also has the function of increasing the length of the bolt threading, thereby increasing the firmness of the fastening. The shape of the mounting column 112 can be a cylinder, a quadrangular prism, etc.

[0049] The present application provides four mounting posts 112, wherein one is provided on the upper and lower sides of the A-pillar connecting frame 12, and one is provided on the upper and lower sides of the instrument panel cross beam body 11. The center lines of the four mounting posts 112 are connected to form a trapezoidal structure, and the reinforcing plate 2 is firmly fixed to the instrument panel cross beam assembly 1 by bolts.

[0050] Of course, the reinforcing plate 2 can also be welded to the instrument panel crossbeam assembly 1 .

[0051] The utility model also uses high-strength materials to increase the impact resistance and load-bearing capacity of the instrument panel crossbeam assembly 1, wherein the instrument panel crossbeam assembly 1 is made of magnesium alloy, and the reinforcing plate 2 is made of steel. Specifically, for the instrument panel crossbeam assembly, based on lightweight considerations, the material of the instrument panel crossbeam assembly is selected from magnesium alloy AM60B, and the material of the front enclosure connecting bracket 3 is selected from high-strength magnesium alloy AZ91D; based on the purpose of improving the overall rigidity of the instrument panel crossbeam assembly, the material of the reinforcing plate is selected from steel DCO1. Through the selection of materials, the instrument panel crossbeam assembly can not only meet the structural and safety performance requirements, but also reduce weight and save costs. The high-strength instrument panel crossbeam assembly also provides effective protection for the safety of passengers in the cab.

[0052] Explain that AM60B is a deformation of magnesium-manganese alloy. Common grades of magnesium alloys are AM50A, AM30, AM60B, MB3, MB8, MB1, MB2, M2M, ME20M, etc. The most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy.

[0053] The AM60B used in the dashboard cross beam assembly of the present application has high elongation and impact resistance, and is commonly used in components such as steering wheels and seats in automobiles. The dashboard cross beam assembly of the present application is made of this material, which can improve the impact resistance of the dashboard cross beam assembly, thereby improving the bending and deformation resistance of the dashboard cross beam assembly, and then improving the safety protection factor of the driver and passengers.

[0054] According to the properties of magnesium alloy, AM50A can also be used for the dashboard crossbeam assembly. This AM50A also has good elongation and impact resistance, and is used in parts such as steering wheels and seats in automobiles.

[0055] The reinforcing plate is made of DCO1 material. DC01 is a low-carbon steel material, belonging to cold-rolled steel plate, with a tensile strength of 270-410 (σb / MPa); yield strength of 130-260 (σs / MPa); elongation after fracture ≧28 (δ5 / %), and has excellent processing performance and mechanical properties. It has a wide range of applications in industrial production. The following is a detailed introduction to DCO1 in terms of material characteristics, uses and processing technology.

[0056] The material properties of DCO1 are mainly reflected in the following aspects: First, its chemical composition contains a low carbon content, usually below 0.12%, so it has good weldability and cold forming properties; second, DCO1 has a high surface quality, good finish and flatness, and is suitable for coating. Third, it has stable mechanical properties, high tensile strength and elongation, and is suitable for manufacturing various parts and structural parts; finally, DCO1 has good surface coating performance, which can effectively prevent corrosion and oxidation and increase the service life of the material.

[0057] DCO1 has a wide range of uses, mainly including the following aspects: First, it is often used to manufacture automotive parts, such as body panels, door panels, etc., because of its good forming performance and surface quality; secondly, DCO1 is also often used to manufacture household appliances, such as refrigerators, washing machines, etc., because of its good weldability and surface coating performance; thirdly, it is also often used to manufacture building structural parts, such as steel structures, pipelines, etc., because of its good mechanical properties and corrosion resistance; finally, DCO1 is also often used to manufacture metal containers and packaging materials, such as food cans, cosmetic bottles, etc., because of its good processing performance and surface quality.

[0058] Therefore, based on the excellent performance of DCO1, this application selects it to make a reinforcement plate to enhance the energy absorption effect.

[0059] See also Figure 6 As shown, the dashboard crossbeam assembly provided by the utility model is also equipped with a front wall connecting bracket 3, which is made of magnesium alloy AZ91D. Magnesium alloy AZ91D is mainly cast by pressure die, and has the characteristics of high specific strength and much higher corrosion resistance than pure magnesium. It is mainly used for housings of electrical products, small-sized thin or special-shaped brackets, etc. Among them, A represents metal aluminum Al, Z represents metal zinc Zn, 9 represents 9% aluminum content, 1 represents 1% zinc content, and the last D is an identification code.

[0060] The instrument panel crossbeam assembly provided by the utility model adopts three different materials, which can not only meet the structural and safety performance requirements, but also contribute to the lightweight of the entire vehicle and save the production cost.

[0061] Combined with the selection of materials for each component, this application also reflects the safety and lightness of the structure from the perspective of thickness control. Specifically, the thickness of the dashboard crossbeam body and the A-pillar connecting frame is 2.5-4mm; the thickness of the front surround connecting bracket is 3.0mm; and the thickness of the reinforcement plate is 1.5mm.

[0062] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0063] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the above-mentioned instrument panel cross beam reinforcement structure.

[0064] The vehicle provided by the utility model adds a reinforcing plate in the transition area where the instrument panel cross beam assembly is connected to the A-pillar. Through the reinforcement of the reinforcing plate and the construction of the annular force transmission channel, the instrument panel cross beam assembly can effectively absorb impact energy and reduce the impact energy transmitted to the A-pillar, thereby reducing the intrusion of the A-pillar into the car's cab and improving the driving safety performance of the car.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
