[0038] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0040] Reference Figures 1 to 6 and Fig.11 As shown, a dashboard tube beam provided in this embodiment includes: a dashboard cross beam 2, extending in the width direction of the vehicle body; a first mounting rod 11, used to connect the front enclosure, and a first end of the first mounting rod 11 is connected to the dashboard cross beam 2; a second mounting rod 12, used to fix the steering column 4, and a first end of the second mounting rod 12 is connected to the dashboard cross beam 2, and an angle is formed between the first mounting rod 11 and the second mounting rod 12 along the rotation direction of the dashboard cross beam 2; a reinforcing rod 13, a portion of the first mounting rod 11 away from its first end is connected to the first end of the reinforcing rod 13, and a portion of the second mounting rod 12 away from its first end is connected to the second end of the reinforcing rod 13, in the direction in which the dashboard cross beam 2 extends, the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 form a triangle, and it should be understood that the first mounting rod 11 and the second mounting rod 12 both extend toward the front side of the vehicle to form a collision structure on the dashboard cross beam 2 for protecting the driver.

[0041] The first mounting rod 11 and the second mounting rod 12 may be overlapped in the extending direction of the instrument panel cross beam 2, or may be spaced a certain distance apart, as long as the second end of the first mounting rod 11 and the second end of the second mounting rod 12 can be connected by the reinforcing rod 13 to form a stable triangular support structure in the extending direction of the instrument panel cross beam 2 (such as Figure 1 ); it should be noted that the first end of the reinforcing rod 13 can be connected to the second end of the first mounting rod 11, or it can be connected to the middle part of the first mounting rod 11, that is, the part between the first end and the second end of the first mounting rod 11, and the second end of the reinforcing rod 13 can be connected to the second end of the second mounting rod 12, or it can be connected to the middle part of the second mounting rod 12, that is, the part between the first end and the second end of the second mounting rod 12; as long as a stable triangular supporting structure can be formed in the extension direction of the dashboard cross beam 2; specifically, the position of the first mounting rod 11 for connecting the reinforcing rod 13 can be 10-50% of its own position close to its second end.

[0042] The instrument panel tube beam provided in this embodiment forms a stable triangular support structure in the extension direction of the instrument panel cross beam 2 by forming an angle between the first mounting rod 11 and the second mounting rod 12 and connecting the first mounting rod 11 and the second mounting rod 12 by using the reinforcing rod 13. The reinforcing rod 13 connects the first mounting rod 11 and the second mounting rod 12 into an integrated structure in cooperation with the instrument panel cross beam 2. There is no need to perform reinforcement treatment and structural alienation treatment on the first mounting rod 11 and the second mounting rod 12 separately to achieve the purpose of strengthening the instrument panel tube beam. Therefore, the overall strength of the instrument panel tube beam can be enhanced while being lighter, lower in cost and simpler in structure. The instrument panel tube beam can not only withstand the weight of the steering column 4 and the vibration of the steering wheel, but also significantly improve the effect of protecting the driver in ODB (Offset Deformable Barrier, frontal offset collision).

[0043] For example, refer to Figures 1 to 6 and Fig.11As shown, the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 is the same, and the number of the three is at least two; at least two first mounting rods 11 are arranged in the extension direction of the dashboard cross beam 2, and the first end of each first mounting rod 11 is connected to the dashboard cross beam 2, the first ends of at least two reinforcing rods 13 are correspondingly connected to the parts of the at least two first mounting rods 11 away from the first ends thereof, and the parts of the at least two second mounting rods 12 away from the first ends thereof are correspondingly connected to the second ends of the at least two reinforcing rods 13, the first end of each second mounting rod 12 is connected to the dashboard cross beam 2, and the first ends of the at least two second mounting rods 12 are respectively arranged opposite to the first ends of the at least two first mounting rods 11, and the first end and the second end of each reinforcing rod 13 are respectively connected to the first mounting rod 11 and the second mounting rod 12 corresponding thereto, so as to form at least two triangles in the extension direction of the dashboard cross beam 2; it should be understood that the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 can be two or more, such as two, three, four, etc.; Specifically, when the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 is an even number, the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 can be divided into two groups and symmetrically arranged on both sides of the steering column 4 in the width direction of the vehicle body. When the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 is an odd number, after ensuring that at least two first mounting rods 11, two second mounting rods 12 and two reinforcing rods 13 are symmetrically arranged on both sides of the steering column 4 in the width direction of the vehicle body, one or more groups of first mounting rods 11, second mounting rods 12 and reinforcing rods 13 can be additionally arranged at the positions that need to be reinforced, as long as the overall strength of the instrument panel tube beam can be improved and the supporting effect on the steering column 4 can be improved; such an arrangement can not only further improve the overall strength of the entire instrument panel tube beam and improve the safety performance, but also provide more connection points for structures such as the steering column 4 and the head-up display device 3 to increase the safety and stability of the vehicle itself, and can also indirectly improve the NVH performance of the vehicle to avoid amplifying the vibration generated by the steering wheel and the steering column 4.

[0044] In some embodiments, the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 are all two; the instrument panel tube beam further includes at least one transverse tie rod 14, and the two ends of at least one transverse tie rod 14 are respectively connected to the second ends of the two first mounting rods 11, and / or the two ends of at least one transverse tie rod 14 are respectively connected to the second ends of the two second mounting rods 12; wherein, when the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 are all three, four or other numbers greater than two, the two ends of the transverse tie rod 14 can be connected to the second ends of the two adjacent first mounting rods 11, and can also be connected to the two spaced first mounting rods 11, and at the same time, the two ends of the transverse tie rod 14 can be connected to the second ends of the two adjacent second mounting rods 12, and can also be connected to the two spaced first mounting rods 11. The second mounting rod 12 is connected, and the end of the tie rod 14 can be connected to the middle part of the first mounting rod 11 or the middle part of the second mounting rod 12, and the two ends of the tie rod 14 are not limited to being connected to the second end of the first mounting rod 11 and the second end of the second mounting rod 12; it should be understood that the extension direction of the tie rod 14 can be parallel to the extension direction of the dashboard cross beam 2, that is, it extends along the width direction of the vehicle body, thereby connecting multiple triangular fixing frames into an integrated structure, further improving the integrity and stability of the multiple triangular fixing frames, and further providing more connection points for structures such as the steering column 4 and the head-up display device 3, so as to increase the safety and stability of the vehicle itself, and can also indirectly improve the NVH performance of the vehicle and avoid amplifying the vibration generated by the steering wheel and the steering column 4.

[0045] Continue to refer to Figure 2 As shown, the number of the first mounting rod 11, the second mounting rod 12 and the reinforcing rod 13 are all two; the instrument panel tube beam also includes at least one reinforcing rod 15, and the two ends of at least one reinforcing rod 15 are correspondingly connected to the first end and the second end of the two first mounting rods 11. It should be understood that one end of the reinforcing rod 15 is connected to the first end of one of the first mounting rods 11, and the other end of the reinforcing rod 15 is connected to the second end of the other first mounting rod 11, thereby forming an oblique rod structure, forming a tripod support structure between the two first mounting rods 11, and / or the two ends of at least one reinforcing rod 15 are correspondingly connected to the first ends of the two second mounting rods 12. It should be understood that one end of the reinforcement rod 15 is connected to the first end of one of the second mounting rods 12, and the other end of the reinforcement rod 15 is connected to the second end of the other second mounting rod 12, thereby forming an inclined rod structure, and forming a tripod support structure between the two second mounting rods 12; wherein the reinforcement rod 15 can also be connected at one end to the first end of a first mounting rod 11, and the other end to the second end of a second mounting rod 12, so as to cooperate with the reinforcement rod 13, so that the instrument panel tube beam forms a plurality of triangular support structures with different support directions, so as to improve the strength and rigidity of the entire instrument panel tube beam at multiple angles.

[0046] Exemplarily, the two second mounting rods 12 are located between the two first mounting rods 11, and a column mounting portion 121 connected to the steering column 4 is formed on the two second mounting rods 12; the column mounting portion 121 can be a fixed space for fixing the steering column 4, or it can be a fixing plate, a fixing bolt, a fixing point, etc. used by the specific second mounting rod 12 to be connected to the steering column 4; specifically, the two second mounting rods 12 can be in the same extension direction as the steering column 4, and are symmetrically arranged on both sides of the steering column 4 along an axial plane extending in the extension direction of the steering column 4, thereby providing a more stable and reliable support effect for the steering column 4, and the steering column 4 can be stably supported and fixed regardless of whether the steering wheel is turned forward or reversed.

[0047] Continue to refer to Figure 1 and Fig.11 As shown, the first mounting rod 11 extends along the length direction of the vehicle body, and the length of the second mounting rod 12 is smaller than the first mounting rod 11; in the ODB (Offset Deformable Barrier, frontal offset collision) working condition, the first mounting rod 11 can be used to bear the main collision force first, and when the first mounting rod 11 collapses, the force is transmitted to the reinforcing rod 13 and the second mounting rod 12, so that the triangular support structure formed by the first mounting rod 11, the second mounting rod 12, the reinforcing rod 13 and the dashboard cross beam 2 absorbs most of the impact.

[0048] Continue to refer to Figure 6 As shown, Figure 6 The dotted part is the instrument panel tube beam structure in this application, which forms an M-shaped support structure. In the ODB (Offset Deformable Barrier, frontal offset collision) condition, it can play a good supporting effect, and at the same time it can also form a buffer, reduce the probability of driver injury, and improve the safety of the entire vehicle.

[0049] Continue to refer to Figure 4 , Figure 5 and Fig.10As shown, a crush notch 111 is provided on the first mounting rod 11 along the vehicle body height direction; in an ODB (Offset Deformable Barrier, frontal offset collision) condition, the first mounting rod 11 can be used to bear the main collision force first, and while the first mounting rod 11 bears the collision force, the crush notch 111 can be used to make the first mounting rod 11 collapse in its extension direction, thereby utilizing its collapse for energy absorption and buffering; specifically, the crush notches 111 on the two first mounting rods 11 can be arranged on a side away from each other, so that when the first mounting rods 11 collapse and deform, the two first mounting rods 11 are bent toward each other at positions corresponding to the crush notches 111, thereby continuing to form a collision structure that can reduce the impact force on the front side of the driver.

[0050] In some embodiments, the extension direction of the reinforcing rod 13 forms an angle with the length direction of the vehicle body. It should be understood that the reinforcing rod 13 is not located in a plane perpendicular to the length direction of the vehicle body, that is, the extension direction of the reinforcing rod 13 has at least one component parallel to the length direction of the vehicle body; by setting the extension direction of the reinforcing rod 13 in this way, the reinforcing rod 13 itself can directly absorb part of the impact force extending along the length direction of the vehicle body under ODB (Offset Deformable Barrier, frontal offset collision) conditions, thereby further improving the safety of the vehicle under ODB (Offset Deformable Barrier, frontal offset collision) conditions.

[0051] Continue to refer to Figures 1 to 6 As shown, the second end of the first mounting rod 11 is provided with a front enclosure connecting bolt 113, and the second end of the first mounting rod 11 can be connected and fixed to the front enclosure by the front enclosure connecting bolt 113. The second end of the first mounting rod 11 can also be connected and fixed to the front enclosure by welding, bonding, clamping, etc.

[0052] In the second aspect, the present application provides a vehicle, including a front enclosure, a head-up display device 3, a steering column 4 and the instrument panel tube beam as described above; the front enclosure is mounted on the second end of a first mounting rod 11, the first mounting rod 11 is provided with at least one first threaded opening 112, and the head-up display device 3 is threadedly connected to the first threaded opening 112 via a first connecting bolt 5; a column mounting structure is provided between the first end and the second end of the second mounting rod 12, and a portion of the steering column 4 is connected to the column mounting structure.

[0053] Reference Figure 5As shown, the head up display device 3 (Head up Display, HUD) can be installed on the first threaded opening 112 on the first mounting rod 11 by means of the first connecting bolt 5. Specifically, the first mounting rod 11 is also provided with a HUD positioning hole 114 for positioning the head up display device 3. When the head up display device 3 is installed, a preliminary connection between the head up display device 3 and the first mounting rod 11 can be achieved first, so as to prevent the head up display device 3 from being installed at a position deviation or an angle offset.

[0054] The vehicle can utilize the above-mentioned instrument panel tube beam to improve the safety of the entire vehicle under ODB (Offset Deformable Barrier, frontal offset collision) conditions, and can also improve the connection rigidity between the head-up display device 3 and the steering column 4.

[0055] In some embodiments, the dashboard tube beam also includes at least one column fixing block 16 arranged on the dashboard cross beam 2, the column fixing block 16 and the column mounting structure are arranged in the extension direction of the steering column 4, and a portion of the steering column 4 is connected to the column fixing block 16.

[0056] Specifically, refer to Figures 1 to 10 As shown, the second mounting rod 12 and the column fixing block 16 can be extruded aluminum parts, which can further improve the connection strength between the steering column 4 and the instrument panel tube beam, and further improve the support stability and reliability of the instrument panel tube beam to the steering column 4. The first mounting rod 11 and the reinforcing rod 13 can be stamped parts; refer to Fig.11 and Fig.12 As shown, in other embodiments, the first mounting rod 11 , the second mounting rod 12 , the column fixing block 16 and the reinforcing rod 13 may all be stamped parts.
