In combination with Figure 4 and Figure 5 shown, in an exemplary embodiment, the bracket 100 is used to connect between the front shock tower package 200 and the vehicle body 300.

[0042] As shown in Figure 4 , the automobile 1000 provided by the present application comprises a vehicle body 300 and a front shock tower package 200, and the front shock tower package 200 is mounted on the vehicle body 300. The automobile 1000 further comprises front wheels 400 connected to the vehicle body 300, and the front shock tower package 200 is used for damping the front wheels 400. Exemplarily, the automobile 1000 comprises two front wheels 400 and two front shock tower packages 200.

[0043] The bracket 100 of the present application comprises a first mounting seat 1, a first supporting rod 2, a sleeve body 3, a second supporting rod 4, and a second mounting seat 5. The first supporting rod 2, the sleeve body 3, and the second supporting rod 4 are connected in sequence and can be coaxially arranged. The first mounting seat 1 is connected to one end of the first supporting rod 2, and the second mounting seat 5 is connected to one end of the second supporting rod 4. With respect to the extension direction of the first supporting rod 2, the first mounting seat 1 and the second mounting seat 5 can each have a certain deflection. The first mounting seat 1 is used to connect the front shock tower package 200, and the second mounting seat 5 is used to connect the vehicle body 300. The bracket 100 has a small size, which can save assembly space.

[0044] The sleeve body 3 is sleeved on the first supporting rod 2 and the second supporting rod 4, so that the size of the sleeve body 3 is greater than that of the first supporting rod 2 and greater than that of the second supporting rod 4. Along a certain radial direction of the first supporting rod 2, the first mounting seat 1 also protrudes from the first supporting rod 2; along a certain radial direction of the second supporting rod 4, the second mounting seat 5 protrudes from the second supporting rod 4. The first mounting seat 1 as a whole and the second mounting seat 5 as a whole can be deflected to different angular positions. By sleeving the sleeve body 3 on the first supporting rod 2 and the second supporting rod 4, the overall performance of the bracket 100 can be improved.

[0045] The front shock tower pack 200 is connected to the vehicle body 300 by the bracket 100, so that the front shock tower pack 200 is reinforced. The bracket 100 of the present application helps to improve the dynamic stiffness of the front shock tower pack 200 and helps to optimize the NVH index of the vehicle 1000.

After the sleeve body 3 is sleeved on the first support rod 2, the first weld 31 can be formed at the step; after the sleeve body 3 is sleeved on the second support rod 4, the second weld 32 can be formed at the step. The sleeve body 3 can be provided with a vent hole to communicate the inside and outside. The sleeve body 3 has high welding strength, which can ensure the connection strength and improve the dynamic stiffness of the front shock tower pack 200.

[0048] Exemplarily, the first support rod 2 can be a hollow rod, and the second support rod 4 can be a hollow rod, which can reduce the weight.

The corresponding sleeve body 3 can be designed after the bracket 100 is simulated or tested. The wall thickness of the sleeve body 3 can be 3mm.

[0050] Reference Figure 1 The outer contour of the cross section of the first support rod 2 is circular, and the structural strength of the first support rod 2 is better; the outer contour of the cross section of the second support rod 4 can also be circular. The first support rod 2 can be a cylindrical rod or a cylinder. The sleeve body 3 can be substantially contoured outside the first support rod 2 and the second support rod 4, for example, the sleeve body 3 is a circular ring sleeve, which is convenient to hold, and then the bracket 100 can be conveniently installed and taken. In some optional embodiments, the cross-sectional shape of the first support rod 2 or the second support rod 4 is other shapes, and then the inner ring shape of one end of the sleeve body 3 corresponding to the first support rod 2 can be fitted to the first support rod 2, and the inner ring shape of one end of the sleeve body 3 corresponding to the second support rod 4 can be fitted to the second support rod 4.

[0054] The second mounting seat 5 can include a second mounting plate 51. The second mounting plate 51 can be provided with a second mounting hole 102, and then another bolt can pass through the second mounting hole 102 to connect the second mounting plate 51 to the vehicle body 300. The second mounting plate 51 is deflected relative to the second support rod 4, and the second mounting plate 51 supports the second support rod 4 while ensuring that it is firmly connected to the vehicle body 300.

[0055] The bracket 100 can have only two mounting holes, and then two bolts can be used to install the bracket 100 to the vehicle body 300 and the front shock absorber tower package 200, which can improve the production rhythm, has no excessive requirement on the process procedure, and the installation process of the bracket 100 is simple. One of the first mounting hole 101 and the second mounting hole 102 is a circular hole, and the other is an oblong hole, which can absorb manufacturing deviations. Exemplarily, the first mounting hole 101 is an oblong hole, which is conducive to adjustment at the front shock absorber tower package 200 and ensures the firm connection of the bracket 100 and the vehicle body 300. Exemplarily, the long axis of the oblong hole is coplanar with the axial direction of the first support rod 2.

In addition, the first mounting plate 11 is substantially flat, which facilitates the compression of the nut. The first flange 12 is substantially cylindrical, which is beneficial to the structural strength of the first mounting seat 1 and facilitates installation.

[0057] The top end of the first flange 12 can be beveled, the bevel is inclined from the first mounting plate 11 to the first support rod 2. The shape of the first flange 12 is beneficial to weight reduction, better exposure of the first mounting hole 101 for facilitating installation and disassembly, and guaranteeing the support of the first mounting plate 11 and the first support rod 2, and the structural strength of the bracket 100.

In addition, the second mounting plate 51 can also be substantially flat, which facilitates the compression of the nut. By providing the second flange 52, the structural strength of the second mounting seat 5 can be improved.

[0059] In combination Figure 3 As shown, the second support rod 4 can be connected to the second mounting plate 51, and then the second flange 52 can not completely surround the second mounting plate 51, but comprise two connection ends 521 spaced from each other.
