[0040] The leaf spring integrated bracket 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] The leaf spring integrated bracket 1 according to an embodiment of the present invention includes a vehicle frame mounting plate 100, a connecting cross plate 200, a first leaf spring arm 300, a second leaf spring arm 400, and an after-treatment assembly mounting plate 500.

[0042] The frame mounting plate 100 extends vertically and is adapted to be mounted on the frame longitudinal beam 10. The connecting cross plate 200 extends horizontally and is connected to the bottom of the frame mounting plate 100. The first leaf spring support arm 300 and the second leaf spring support arm 400 are spaced apart on the connecting cross plate 200, and the first leaf spring support arm 300 and the second leaf spring support arm 400 are respectively located on both sides of the frame mounting plate 100 in the thickness direction. The aftertreatment assembly mounting plate 500 is connected to the frame mounting plate 100 and the connecting cross plate 200. The aftertreatment assembly mounting plate 500 is configured with a straight groove 510 extending along its length direction. Upper mounting portions 520 and lower mounting portions 530 are respectively formed on the upper and lower sides of the straight groove 510. The upper mounting portions 520 and the lower mounting portions 530 are adapted to mount the aftertreatment assembly by passing through fasteners.

[0043] For example, the straight groove 510 can be formed on the opposite sides of the aftertreatment assembly mounting plate 500 in the thickness direction, so that the cross section of the aftertreatment assembly mounting plate 500 is configured in a "work" shape. The straight groove 510 can also be formed on one side of the aftertreatment assembly mounting plate 500 in the thickness direction, so that the cross section of the aftertreatment assembly mounting plate 500 is configured in a "C" shape. The leaf spring integrated support 1 is made of nodular iron and has a high elongation rate. The aftertreatment assembly mounting plate 500 is perpendicular to the frame mounting plate 100, so that the aftertreatment assembly mounting plate 500 extends outward from the frame longitudinal beam 10 to adapt to the installation position of the aftertreatment assembly. The aftertreatment assembly can be mounted on the aftertreatment assembly mounting plate 500 outside the frame longitudinal beam 10.

[0044] According to the leaf spring integrated support 1 of the embodiment of the present invention, the aftertreatment assembly mounting plate 500 is integrally constructed through the leaf spring integrated support 1. The aftertreatment assembly mounting plate 500 is respectively connected to the connecting cross plate 200 and the frame mounting plate 100, and the connection area is large and the structural strength is high. Moreover, the aftertreatment assembly mounting plate 500 makes full use of the space above the connecting cross plate 200, and there is no need to additionally provide a bracket for mounting the aftertreatment assembly, so the integration degree is high.

[0045] Furthermore, by constructing the straight groove 510 on the aftertreatment assembly mounting plate 500, the straight groove 510 can not only reduce the weight of the aftertreatment assembly mounting plate 500, but also form the upper mounting portions 520 and the lower mounting portions 530 on the upper and lower sides of the straight groove 510 respectively, so that the upper mounting portions 520 and the lower mounting portions 530 are spaced apart. The upper mounting portions 520 and the lower mounting portions 530 can adapt to the surface fitting of the aftertreatment assembly. The upper mounting portions 520 and the lower mounting portions 530 can respectively maintain good fitting with the aftertreatment assembly, and the aftertreatment assembly is more firmly assembled through the fasteners on the upper mounting portions 520 and the lower mounting portions 530.

[0046] Therefore, the leaf spring integrated support 1 according to the embodiment of the present invention has the advantages of high integration degree, high degree of light weight, good fitting property, etc.

[0047] In some specific embodiments of the present invention, such as Figure 3 As shown, the frame mounting plate 100 is provided with a plurality of frame mounting holes 11, and one of the frame mounting holes 11 corresponds to the extension path position of the straight groove 510. That is, the extension line of the axis of one of the frame mounting holes 11 is within the straight groove.

[0048] Due to the space limitation of the frame mounting plate 100, in order to prevent the after-treatment assembly mounting plate 500 from affecting the assembly of fasteners in the frame mounting holes 11, by constructing the straight groove 510 on the frame mounting plate 100, the extension line of one of the frame mounting holes 11 can be made to be within the straight groove 510, and the fastener passing through this frame mounting hole 11 can also extend in from the straight groove 510, ensuring the firmness of the installation of the frame mounting plate 100 and the frame longitudinal beam 10.

[0049] In some specific embodiments of the present invention, such as Figure 5 As shown, a plurality of frame mounting holes 11 are arranged in an array on the frame mounting plate 100, and the distances between adjacent frame mounting holes 11 are equal. The distribution of the plurality of frame mounting holes 11 is relatively uniform, and the force is more balanced.

[0050] Furthermore, as Figure 5 As shown, the plurality of frame mounting holes 11 include a first mounting hole 101, a second mounting hole 102, a third mounting hole 103, a fourth mounting hole 104, and a fifth mounting hole 105.

[0051] The connecting lines of the first mounting hole 101, the second mounting hole 102, the third mounting hole 103, the fourth mounting hole 104, and the fifth mounting hole 105 are configured as a right trapezoid, and the fourth mounting hole 104 corresponds to the extension path position of the straight groove 510.

[0052] Among them, the first mounting hole 101 and the second mounting hole 102 are arranged in the first row, and the third mounting hole 103, the fourth mounting hole 104, and the fifth mounting hole 105 are arranged in the second row. The first mounting hole 101 is directly above the fourth mounting hole 104, the second mounting hole 102 is directly above the third mounting hole 103, and the fifth mounting hole 105 and the third mounting hole 103 are respectively on both sides of the fourth mounting hole 104.

[0053] The frame mounting plate 100 is connected to multiple parts of the frame longitudinal beam through a plurality of frame mounting holes 11 by fasteners. By corresponding the fourth mounting hole 104 to the extension path of the straight groove 510, when the leaf spring integrated bracket 1 is installed on the frame longitudinal beam 10 through the fourth mounting hole 104, the fastener can be inserted into the fourth mounting hole 104 along the extension direction of the straight groove 510, and when the fastener is assembled, it can be conveniently inserted into and fastened to the fastener of the fourth mounting hole from the straight groove 510.

[0054] In some specific embodiments of the present invention, such as Figure 5As shown, the frame mounting plate 100 is configured with a ring platform 110 surrounding the frame mounting hole 11. The outer contour of the ring platform 110 is configured as a cylinder and protrudes from the opposite two side surfaces of the frame mounting plate 100.

[0055] By configuring the ring platform 110 surrounding the frame mounting hole 11 on the frame mounting plate 100, fasteners such as bolts can abut against the ring platform 110, improving the connection strength between the frame mounting plate 100 and the frame. And the ring platform 110 has a relatively thick thickness on the radially outer side of the frame mounting hole 11, ensuring the structural strength in the radial direction of the frame mounting hole 11 after the fastener passes through the frame mounting hole 11.

[0056] Furthermore, as Figure 5 shown, on the side of the frame mounting plate 100 facing away from the post-treatment assembly mounting plate, a frame border reinforcing rib 120 connecting adjacent ring platforms 110 is configured.

[0057] Specifically, between the ring platform 110 of the first mounting hole 101 and the ring platform 110 of the second mounting hole 102, between the ring platform 110 of the second mounting hole 102 and the ring platform 110 of the third mounting hole 103, between the ring platform 110 of the third mounting hole 103 and the ring platform 110 of the fourth mounting hole 104, between the ring platform 110 of the fourth mounting hole 104 and the ring platform 110 of the fifth mounting hole 105, and between the ring platform 110 of the fifth mounting hole 105 and the ring platform 110 of the first mounting hole 101, frame border reinforcing ribs 120 are all connected. In addition, below the ring platforms 110 of the third mounting hole 103, the fourth mounting hole 104, and the fifth mounting hole 105, vertical reinforcing ribs 130 extending vertically downward are configured, and the vertical reinforcing ribs 130 extend to connect to the connecting cross plate 200.

[0058] In some specific embodiments of the present invention, as Figure 3 shown, at the connection between the second leaf spring arm 400 and the connecting cross plate 200, an inclined platform 210 extending obliquely is configured. At the bottom of the post-treatment assembly mounting plate 500, a support portion 540 extending obliquely downward is configured. The support portion 540 is connected to the inclined platform 210 and is connected to the second leaf spring arm 400. For example, the top surface of the inclined platform 210 forms an angle of 45° with the horizontal direction. By connecting the inclined platform 210 with the support portion 540, the connection strength of the post-treatment assembly mounting plate 500 can be stabilized, and when the post-treatment assembly mounting plate 500 is subjected to an impact, the inclined platform 210 can provide better support and has higher strength to cope with the impact load condition.

[0059] In some specific embodiments of the present invention, as Figure 2 and Figure 3As shown, the outer contour of the side of the first leaf spring support arm 300 facing the second leaf spring support arm 400 is configured with a first reinforcing frame 310, and the outer contour of the side of the second leaf spring support arm 400 facing the first leaf spring support arm 300 is configured with a second reinforcing frame 410.

[0060] Among them, the thickness of the first reinforcing frame 310 is greater than the thickness of the remaining part of the first leaf spring support arm 300, and the thickness of the second reinforcing frame 410 is greater than the thickness of the remaining part of the second leaf spring support arm 400. The first leaf spring support arm 300 configures the first reinforcing frame 310, and the second leaf spring support arm 400 configures the second reinforcing frame 410, so that the first leaf spring support arm 300 and the second leaf spring support arm 400 form a relatively high strength. And the thickness at the center of the first leaf spring support arm 300 and the center of the second leaf spring support arm 400 is relatively small, which improves the lightweight degree of the leaf spring integrated support 1 on the premise of ensuring the structural strength of the first leaf spring support arm 300 and the second leaf spring support arm 400.

[0061] In some specific embodiments of the present invention, as Figure 2 and Figure 3 shown, the side of the first leaf spring support arm 300 facing the second leaf spring support arm 400 is also configured with a first reinforcing rib 320. The first reinforcing rib 320 is located in the middle of the width direction of the first leaf spring support arm 300 and extends vertically to connect to the connecting cross plate 200. The side of the second leaf spring support arm 400 facing the first leaf spring support arm 300 is also configured with a second reinforcing rib 420. The second reinforcing rib 420 is located in the middle of the width direction of the second leaf spring support arm 400 and extends vertically.

[0062] The first reinforcing rib 320 protrudes from the inner surface of the first leaf spring support arm 300. The first reinforcing rib 320 can be reinforced in the middle of the width direction of the first leaf spring support arm 300. The second reinforcing rib 420 protrudes from the inner surface of the second leaf spring support arm 400. The second reinforcing rib 420 can be reinforced in the middle of the width direction of the second leaf spring support arm 400. And the first reinforcing rib 320 extends to the bottom of the connecting cross plate 200 and extends horizontally along the connecting cross plate 200, so that the first leaf spring support arm 300, the second leaf spring support arm 400 and the connecting cross plate 200 all have relatively high structural strength.
