[0028] Embodiment 1

[0029] Referring to Figures 1 - 2 , a tower package strengthening structure provided by the present utility model is shown. This tower package strengthening structure can effectively solve the problem of weakened structural strength caused by sudden angle change in the large corner position of the tower package and improve the dynamic stiffness of the upper mounting point of the suspension. Without changing the overall dimensions of the vehicle frame, multiple strengthening structures are used to enhance the strength of the large corner of the tower package and the dynamic stiffness of the upper mounting point of the suspension, avoiding the generation of excessive noise by the engine during vehicle operation.

[0030] As Figure 1As shown in the figure, a tower package strengthening structure provided by an embodiment of the present utility model includes a first strengthening member 1 and a second strengthening member 2 installed on a tower package body 7. A suspension upper mounting point 4 is provided on the tower package body 7, and the suspension upper mounting point 4 is located between the first strengthening member 1 and the second strengthening member 2. The first strengthening member 1 and the second strengthening member 2 form an eight-shaped strengthening beam on both sides of the suspension upper mounting point 4. A first longitudinal beam 5 and a second longitudinal beam 6 of a vehicle are provided on both sides of the tower package body 7. The first end of the first strengthening member 1 and the first end of the second strengthening member 2 are both connected to the first longitudinal beam 5, and the second end of the first strengthening member 1 and the second end of the second strengthening member 2 are both connected to the second longitudinal beam 6; the first strengthening member 1 and the second strengthening member 2 are fixed between the first longitudinal beam 5 and the second longitudinal beam 6, and the suspension upper mounting point 4 is arranged between the first strengthening member 1, the second strengthening member 2, the first longitudinal beam 5 and the second longitudinal beam 6. Through the connection between the first strengthening member 1, the second strengthening member 2, the first longitudinal beam 5 and the second longitudinal beam 6, a closed annular structure is jointly formed around the suspension upper mounting point 4, thereby realizing the enhancement of the local stiffness of the suspension upper mounting point 4.

[0031] In one embodiment, the tower package body 7 includes a first side wall and a second side wall, and there is a bending angle between the first side wall and the second side wall. The first strengthening member 1 and the second strengthening member 2 are arranged on the side with a larger bending angle of the tower package body 7, that is, the first strengthening member 1 and the second strengthening member 2 are arranged on the outside of the tower package body 7 without occupying the internal layout space.

[0032] Correspondingly, as Figure 2 shown, both the first strengthening member 1 and the second strengthening section 2 include a first bending section 11, a strengthening section 12 and a second bending section 13. The first bending section 11 and the second bending section 13 are connected to both ends of the strengthening section 12. The first bending section 11 and the second bending section 13 are arranged in a vertical sheet-like structure, so that the first bending section 11 and the second bending section 13 can be attached to the sides of the first longitudinal beam 5 and the second longitudinal beam 6. The first bending section 11 and the second bending section 13 are respectively fixed to the sides of the first longitudinal beam 5 and the second longitudinal beam 6 by means of planar lapping, improving the stiffness of the joint.

[0033] Specifically, in order to realize the mutual cooperation between the connection structures, the first longitudinal beam 5 includes an inner plate, and the outer plate of the second longitudinal beam 6 is not shown in the figure. The first bending section 11 of the first strengthening member 1 and the second strengthening member 2 is connected to the inner plate of the first longitudinal beam 5, and the second bending section 13 of the first strengthening member 1 and the second strengthening member 2 is connected to the outer plate of the second longitudinal beam 6. In order to improve the strength of the inner plate of the first longitudinal beam 5 and the outer plate of the second longitudinal beam 6 itself, the first strengthening member 1 and the second strengthening member 2 are connected to the inner plate of the first longitudinal beam 5 and the outer plate of the second longitudinal beam 6 by spot welding.

[0034] As Figure 2As shown, the reinforcement section 12 includes a first reinforcement body 12-1 and a first flange structure 12-2. The first flange structure 12-2 is located on both sides of the first reinforcement body 12-1 and is used to be connected to the tower package body 7. There is a gap between the first reinforcement body 12-1 and the first flange structure 12-2 and the tower package 7. As a preferred embodiment, the reinforcement section 12 is a "J"-shaped structure. The first reinforcement body 12-1 is located on the side of the first flange structure 12-2 away from the tower package body 7. The first flange structure 12-2 is arranged on both sides of the first reinforcement body 12-1. A cavity is formed between the first reinforcement body 12-1 and the first flange structure 12-2 and the tower package body 7, so that the reinforcement section has higher stability and support. At the same time, the first reinforcement member 1 and the second reinforcement member 2 have the same structure, providing support for the suspension upper mounting point 4 from both sides at the same time, and providing sufficient rigidity and strength for the suspension upper mounting point 4.

[0035] It should be noted that the first flange structure 12-2 is fixed to the first side outer wall and the second side outer wall of the tower package 7 respectively, and the connection between the first side wall and the second side wall of the tower package body 7 is the large corner of the tower package body 7. The large corner cross-section suddenly changes, causing structural weakening. Specifically, the first flange structure 12-2 is spot welded on the outer surface of the tower package body 7, wherein the first flange structure 12-2 on the left side is welded on the horizontal plane of the tower package body 7, and the first flange structure 12-2 on the right side is welded on the plane extending downward from the tower package body 7. The cavity between the first flange structures 12-2 surrounds the large corner angle mutation position of the tower package body 7, so that the structural weakness caused by the large corner cross-section mutation of the tower package body 7 is set in the cavity reinforcement structure, thereby improving the structural stiffness of the structural mutation position.

[0036] In one embodiment, referring to Figure 1, the tower package strengthening structure further includes a third strengthening member 3. The third strengthening member 3 includes a third strengthening body 31 and third flanging structures 32 located on both sides of the third strengthening body 31. The third flanging structures 32 are connected to the tower package 7, and there is a gap between the third strengthening body 31 and the tower package 7. As a preference, the third strengthening member 3 is arranged as a "ji" - shaped strengthening structure. The third flanging structures 32 are arranged around the third strengthening body 31. A cavity is formed between the third strengthening body 31, the third flanging structures 32 and the tower package body 7, and a cavity is formed between the third strengthening member 3 and the tower package body 7. Its stiffness is much higher than that of the flat plate strengthening structure, making the strengthening section have higher stability and support. It should be noted that both ends of the third strengthening body 31 are respectively connected to the first strengthening member 1 and the second strengthening member 2. The traditional upper mounting point 4 of the suspension is fixed on a thin plate. In this embodiment, a strengthening beam jointly composed of the first strengthening member 1, the second strengthening member 2 and the third strengthening member 3 is arranged around the upper mounting point 4 of the suspension. The strengthening beam and the first longitudinal beam 5 and the second longitudinal beam 6 jointly form a plurality of closed ring - shaped structures. The upper mounting point 4 of the suspension is arranged in the closed ring - shaped structure, further enhancing the local stiffness of the upper mounting point 4 of the suspension.

[0037] Specifically, the right end of the third flanging structure 32 abuts against the first flanging structure 12 - 2 on the left side of the first strengthening member 1, and the left end of the third flanging structure 32 abuts against the first flanging structure 12 - 2 on the right side of the second strengthening member 2, avoiding the generation of gaps when the third strengthening member 3 is connected to the first strengthening member 1 and the second strengthening member 2.

[0038] In this embodiment, the orthographic projection of the third strengthening member 3 on the tower package body 7 does not overlap with the upper mounting point 4 of the suspension, which is convenient for setting bolts at the upper mounting point 4 of the suspension.

[0039] A tower package body strengthening structure provided by the present utility model spot - welds a first strengthening plate 1 and a second strengthening plate 2 between the first longitudinal beam 5 and the second longitudinal beam 6, and arranges an eight - shaped double strengthening plate on the tower package body 7. In addition, the strengthening plate will cross the structural weakness at the large corner of the tower package body 7, solving the problem of structural weakening caused by sudden cross - section change. In addition, a third strengthening member 3 is welded between the first strengthening plate 1 and the second strengthening plate 2. The three strengthening plates form a plurality of closed ring - shaped structures to enhance the upper mounting point 4 of the suspension, greatly improving the dynamic stiffness of the upper mounting point 4 of the suspension. In addition, the strengthening plates are all installed on the outer side of the tower package body 7, without occupying the internal layout space, and there is no need to adjust the frame size. And the connection of the strengthening members and the connection between the strengthening members and the tower package body 7 are all carried out by spot - welding process, with simple process and high feasibility.
