[0040] The dashboard crossbeam is an important load-bearing component in the vehicle cabin. The dashboard, controller, steering wheel, etc. are all fixed on it. In addition, the dashboard crossbeam spans the left and right sides of the vehicle body, which has a certain strengthening effect on the entire cab. In the related art, a steel bracket is used to connect the front wall of the vehicle and the dashboard crossbeam. However, for the steel bracket, its weight is large and is not conducive to the endurance of the whole vehicle.

[0041] Based on the above problems, the utility model proposes a bracket 1000 for connecting the front enclosure of a vehicle with a dashboard cross beam 2000, which can improve the endurance of the vehicle. Vehicles include but are not limited to sedans, SUVs, off-road vehicles, pickup trucks or other non-track-borne vehicles driven by power. The vehicle can be a new energy vehicle, including pure electric vehicles, hybrid vehicles, plug-in hybrid vehicles and other vehicles that use on-board power batteries as the main power source or one of the power sources, or it can be a traditional fuel vehicle. Figure 1 , Figure 1 This is a schematic structural diagram of a first viewing angle of a bracket of an embodiment of the first aspect of the utility model, Figure 2 for Figure 1 The schematic diagram of the second viewing angle of the middle bracket, the bracket 1000 of this embodiment is a steel-plastic structure, the steel-plastic structure uses steel as the base material, and plastic is coated on the outside of the base material. For example, the bracket 1000 includes a steel frame and plastic-coated accessories. During manufacturing, the steel frame is set in the mold cavity of the mold, and the plastic melt is injected into the mold cavity so that the plastic melt is coated on the outside of the frame, thereby forming an integrated bracket 1000, so that the bracket 1000 has sufficient strength and is lighter in weight than the steel structure.

[0042] The bracket 1000 includes a main body 100 and a first reinforcing rib 200. The main body 100 defines a first groove 130 and a collapse inducing hole 140. The main body 100 has a first surface 150 and a second surface 160 that are opposite to each other. The first surface 150 and the second surface 160 can be planes, but are not limited thereto. They can also be curved surfaces or formed by multiple planes with a certain angle. The first groove 130 has an opening formed on the first surface 150, and the opening is a first notch 131 (such as Figure 1 The inner wall of the first groove 130 opposite to the first notch 131 is the first inner wall 132. In other words, the first groove 130 has the first inner wall 132, and the first inner wall 132 faces the first notch 131. The collapse induction hole 140 communicates with the second surface 160 and the first inner wall 132 (as shown in FIG. Figure 2 As shown in the figure, the number of the crush inducing holes 140 can be any number such as one, two or three. The crush inducing holes 140 can quickly generate crushing to absorb impact energy and impact force, thereby reducing or delaying the displacement of the rear structure of the crush inducing holes 140 (the portion of the main body 100 located in the crush inducing holes 140 facing the connecting portion 120), which is used to improve the crushing performance of the bracket 1000 and reduce the intrusion damage to the passengers. The first reinforcing rib 200 is arranged in the first groove 130 and is connected to the main body 100, which is used to improve the modal performance of the bracket 1000.

[0043] Specifically, it can be understood that in a vehicle, the vehicle steering wheel is a component of the vehicle steering system and is also a component that is relatively easy for the user to directly perceive vibration. The steering wheel is mounted on the steering column, which is mounted on the dashboard cross beam 2000, and the dashboard cross beam 2000 is fixed to the front wall structure of the vehicle body through the bracket 1000. Therefore, if the dashboard cross beam shakes, it will be directly transmitted to the steering wheel and cause the driver's hand to shake. Based on this, it is necessary to consider not only the modal performance and collapse performance of the bracket 1000 during design, wherein the modal performance is the response characteristics of the automobile structure when subjected to dynamic loads (such as vibration, impact, etc.), which affects the shaking of the steering wheel. The collapse performance refers to the controllable deformation of the material in the collision area when a collision occurs, thereby absorbing the energy generated by the collision to reduce the impact on the passengers, thereby reducing the maximum damage that the passengers may suffer. For the steel-plastic structure, since the elastic modulus of the plastic-steel structure is relatively lower than that of the steel structure, simply opening the collapse induction hole 140 will cause the modal performance of the bracket 1000 to be reduced. Based on this, this embodiment connects the first reinforcing rib 200 while setting the collapse inducing hole 140 on the main body 100. Through the synergistic effect of the collapse inducing hole 140 and the first reinforcing rib 200, the bracket 1000 of this embodiment can meet the modal requirements while meeting the collapse performance. Therefore, compared with the steel structure, the bracket 1000 of the steel-plastic structure of this embodiment has a lighter weight while meeting the use requirements. Therefore, when the bracket 1000 of this embodiment is used to connect the front wall and the dashboard cross beam of the vehicle, the overall weight of the vehicle can be made lighter, thereby improving the endurance of the vehicle.

[0044] Reference Figure 2 In some embodiments, the main body includes a crushing portion 110 and a connecting portion 120, the crushing portion 110 is used to connect with the front wall, the connecting portion 120 is used to connect with the instrument panel cross beam 2000, and the first groove 130 is formed in the crushing portion 110. Specifically, the first groove 130 is formed in the crushing portion 110, and the crush induction hole 140 is arranged on the first inner wall 132 of the first groove 130, so that the crushing portion 110 is more likely to expand and contract to absorb energy. Since the crushing portion 110 is used to connect with the front wall, the crushing portion 110 is relatively farther away from the instrument panel cross beam 2000 than the connecting portion 120. Therefore, once the vehicle collides, the crushing deformation is farther away from the passenger, thereby improving the safety of the passenger. Further, in some embodiments, the crush induction hole 140 is located on the side of the first groove 130 away from the connecting portion 120, so that the crush induction hole 140 is farther away from the instrument panel cross beam 2000, thereby further making the crushing deformation part away from the passenger, so as to improve the safety of the passenger.

[0045] In some embodiments, the wall thickness of the portion of the body 100 corresponding to the second surface 160 to the first inner wall 132 is L1, and the wall thickness of the rest of the body 100 is L2, L1<L2, that is, the thickness of the front portion of the bracket 1000 is thinner than the thickness of the rear portion, thereby making it easier for the front portion of the bracket 1000 to collapse and absorb energy, so that the part where the vehicle crashes and collapses is far away from the passengers in the vehicle. Figure 2 As shown in the example, the first groove 130 of the main body 100 is further defined with a second groove 170 on one side facing the connecting portion 120, the second groove 170 forms a second notch 171 on the second surface 160, and the inner wall of the second groove 170 opposite to the second notch 171 is a second inner wall 172, and the main body 100 further includes a second reinforcing rib 400, which is arranged in the second groove 170 and connected to the main body 100. The wall thickness between the second surface 160 and the first inner wall 132 is 2.15mm to 2.25mm, and the wall thickness between the second inner wall 172 and the first surface 150 is 2.45mm to 2.55mm, so that the bracket 1000 is more likely to collapse and deform at the first groove 130 when a collision occurs.

[0046] Reference Figure 3 , Figure 3 for Figure 1 Schematic diagram of the third viewing angle of the middle bracket. In some embodiments, the section plane that vertically divides the main body 100 in the first direction (the first direction is the direction from the collapse portion 110 to the connecting portion 120) is used as the reference plane 300. The collapse portion 110 is an asymmetric structure with respect to the reference plane 300. For example, the reference plane divides the main body 100 into a first portion 111 and a second portion 112. The outer contours of the first portion 111 and the second portion 112 are different, or the shape of the portion of the first groove 130 located in the first portion 111 and the portion located in the second portion 112 are different. Figure 2 and Figure 3 As shown in the example, the first groove 130 includes a first groove body 133 and a second groove body 134, the first groove body 133 is symmetrically arranged with respect to the reference plane, the second groove body 134 protrudes from the first groove body 133, and the second groove body 134 is only formed in the first portion 111, or the second groove body 134 is only formed in the second portion 112, thereby making the first groove 130 an asymmetric plane with respect to the reference plane 300. Therefore, when the crushing portion 110 is impacted, the supporting forces provided by the first portion 111 and the second portion 112 are different, thereby making the bracket 1000 easy to twist when impacted, and further making the bracket 1000 collapse and absorb energy when subjected to a smaller impact force, so as to reduce the impact force of the crushing portion 110 transmitted backward to the connecting portion 120, and reduce the impact force on the instrument panel cross beam 2000, thereby reducing the front wall intrusion, and improving the safety of the passengers in the vehicle.

[0047] It should be noted that the first slot body 133 and the second slot body 134 may be separated by the first reinforcing rib 200, or may be directly connected, such as Figure 3 As shown, attached Figure 3 The dotted line between the first slot body 133 and the second slot body 134 cannot be interpreted as an actual contour line, but is only used to more clearly illustrate the first slot body 133 and the second slot body 134 .

[0048] Reference Figure 4 and Figure 5 , Figure 4 for Figure 1 Schematic diagram of the fourth viewing angle of the middle bracket, Figure 5 for Figure 4 In some embodiments, the first reinforcing rib 200 includes a longitudinal rib 210 extending in a first direction and a transverse rib 220 extending in a second direction (eg, Figure 4 The first direction is the direction from the collapsed portion 110 to the connecting portion 120, and the second direction is perpendicular to the first direction. The longitudinal ribs 210 and the transverse ribs 220 are arranged crosswise, and the end of the transverse ribs 220 away from the first inner wall 132 is arranged inclined along the first direction (as shown in FIG. Figure 5 The longitudinal ribs 210 are used to transfer the impact force received by the crushed portion 110 along the first direction, that is, when the crushed portion 110 is impacted, the impact force can be transferred backward to the transverse ribs 220 through the longitudinal ribs 210. Since the transverse ribs 220 are arranged obliquely along the first direction, when the transverse ribs 220 are subjected to external force along the first direction, they are more likely to bend along the first direction to achieve the purpose of crushing energy absorption, thereby reducing the force transmitted to the connecting portion 120 and reducing the deformation of the instrument panel cross beam 2000, thereby reducing the front wall intrusion and improving the safety of the passengers in the vehicle.

[0049] Reference Figure 6 , Figure 6 for Figure 1Schematic diagram of the fifth viewing angle of the middle bracket. In some embodiments, the main body 100 is bent to form a plurality of bending structures 101. The bending structure 101 includes a first bending portion 102 and a second bending portion 103 connected to each other. The angle between the first bending portion 102 and the second bending portion 103 is α, 0<α<180°, that is, there is a certain inclination angle between the first bending portion 102 and the second bending portion 103. Therefore, after the collapse portion 110 is impacted, the force is transmitted to the connecting portion 120 via the collapse portion 110, and the first bending portion 102 and / or the second bending portion 103 will be subjected to a certain bending moment. Specifically, since there is a certain angle between the first bending portion 102 and the second bending portion 103, during the force transmission process, at least one of the first bending portion 102 and the second bending portion 103 is different from the direction of the force. For example, if the first bending portion 102 extends along the first direction, then the second bending portion 103 must have an angle greater than 0 and less than 180° with the first direction, so that the second bending portion 103 is subjected to a bending moment and is more likely to collapse and absorb energy. In other words, if the second bending portion 103 extends along the first direction, then the first bending portion 102 must have an angle greater than 0 and less than 180° with the first direction, so that the first bending portion 102 is subjected to a bending moment and is more likely to collapse and absorb energy. As a result, the bracket 1000 is more likely to collapse and deform at the bending structure 101, thereby reducing the impact force on the collapse portion 110 and transmitting it to the connection portion 120, thereby reducing the front wall intrusion to improve the safety of passengers in the vehicle.

[0050] It should be noted that the attached Figure 6 The fact that the middle body 100 has one bending structure 101 cannot be interpreted as the only limitation of this embodiment. According to requirements, any number of bending structures 101 such as two, three or four may be provided, as long as the bracket 1000 can be more easily collapsed and absorb energy.

[0051] Reference Figure 7 , Figure 7 The schematic diagram of the structure of the instrument panel cross beam assembly of the second embodiment of the utility model, the instrument panel cross beam assembly of the second embodiment of the utility model comprises: the bracket 1000 of the first embodiment. Specifically, the instrument panel cross beam assembly also comprises an instrument panel cross beam 2000, the connecting portion 120 of the bracket 1000 is connected to the instrument panel cross beam 2000, the collapse portion 110 is used to connect with the front enclosure, the bracket 1000 is a steel-plastic structure, the steel-plastic structure uses steel as the base material, the plastic is coated on the outside of the base material, and the bracket satisfies the modal performance requirements and the collapse performance requirements at the same time through the combined action of the collapse inducing hole and the first reinforcing rib. Therefore, for the bracket of the steel-plastic structure, compared with the steel structure bracket, it has a lighter weight while meeting the use requirements. Therefore, when the instrument panel cross beam assembly of this embodiment is used in a vehicle, the overall weight of the vehicle can be made lighter, thereby improving the vehicle's endurance.

[0052] It should be noted that, since this embodiment adopts all the technical features of the first aspect embodiment, this embodiment has all the beneficial effects brought by the first aspect embodiment, which will not be repeated here.

[0053] The vehicle of the third aspect of the present utility model includes but is not limited to a sedan, SUV, off-road vehicle, pickup truck or other non-track-borne vehicle driven by power. The vehicle can be a new energy vehicle, including a pure electric vehicle, a hybrid vehicle, a plug-in hybrid vehicle and other vehicles that use an on-board power battery as the main power source or one of the power sources, or a traditional fuel vehicle. The vehicle includes: the dashboard crossbeam assembly of the second aspect of the embodiment. Specifically, the vehicle also includes a front wall, and the end of the bracket 1000 in the dashboard crossbeam assembly that is away from the dashboard crossbeam 2000 is connected to the front wall, wherein the bracket 1000 is a steel-plastic structure, the steel-plastic structure uses steel as the base material, and the plastic is coated on the outside of the base material, and the bracket meets the modal performance requirements and the collapse performance requirements at the same time through the combined action of the collapse induction hole and the first reinforcement rib.
