In addition, auxiliary brackets 2 are respectively provided on both sides of the main bracket 1, and each auxiliary bracket 2 is provided with a third connecting part 300, and the third connecting part 300 is used to connect with the vehicle body floor.

[0041] At this time, the first connecting part 100 is set on both sides of the upper part of the main bracket 1, the second connecting part 200 is set on the lower part of the main bracket 1, and the third connecting part 300 is set on the two auxiliary brackets 2, so that the first connecting part 100 and the second connecting part 200 are set on both sides of the third connecting part 300, and the third connecting part 300 and the first connecting part 100 and the second connecting part 200 located on either side are located at the three corner points of the triangle, which can form a stable supporting structure, which is beneficial to improve the structural strength and rigidity of the mounting bracket, so that the auxiliary instrument panel frame 3 can be firmly and reliably fixed to the vehicle body floor, and the deformation of the auxiliary instrument panel frame in the vehicle width direction, that is, the vehicle Y direction, can be better controlled, thereby effectively ensuring the modal of the auxiliary instrument panel frame 3.

[0042] Based on the above overall introduction, in detail, as a preferred implementation, continue to refer to Figures 1 to 5 As shown, in this embodiment, the main bracket 1 is in a "U" shape and includes a middle plate 11 and side plates 12 arranged on both sides of the middle plate 11. The side plates 12 on both sides are respectively provided with a first connection portion 100, and the middle plate 11 is provided with a second connection portion 200. The "U"-shaped main bracket 1 can make way for the storage box set on the auxiliary instrument panel, so as to facilitate the connection with the auxiliary instrument panel frame 3. Moreover, the main bracket 1 of the utility model is suitable for the installation of the auxiliary instrument panel frame 3 without a storage box, and is also suitable for the installation of the auxiliary instrument panel frame 3 with a storage box.

[0043] In this embodiment, as a preferred implementation, the first connecting portion 100 on each side panel 12 includes a first connecting hole 120. In specific implementation, each side panel 12 can be connected to the auxiliary instrument panel frame 3 by a connecting piece inserted through the first connecting hole 120.

[0044] The second connection part 200 includes a lower plane disposed on the lower side of the middle plate 11, and the middle plate 11 is welded to the vehicle body floor through the lower plane. At this time, the second connection part 200 is set as the lower plane, and is welded to the vehicle body floor through the lower plane, which is conducive to increasing the contact area between the main bracket 1 and the vehicle body floor. On the one hand, the main bracket 1 can be stably and reliably supported, and on the other hand, multiple welding points can be set to improve the connection reliability between the main bracket 1 and the vehicle body floor.

[0045] See also Figures 3 to 5 As shown, the middle plate 11 and the side plate 12 are connected by a connecting plate 112. Specifically, the middle plate 11 has a first plate 111, and the two ends of the first plate 111 are respectively connected to connecting plates 112, and the connecting plates 112 at the two ends are symmetrically arranged and inclined in the vehicle body height direction, and the connecting plates 112 on the same side are connected to the side plate 12 together.

[0046] It should be noted that the main bracket 1 and the auxiliary bracket 2 of this embodiment are preferably integrally formed, and the structure is relatively simple and easy to process. In addition, it should be noted that in addition to using the connecting plate 112 to connect the middle plate 11 to the side plate 12, it is also possible not to set the connecting plate 112 and directly connect to the side plate 12. This is also possible.

[0047] See also Figure 3 and Figure 4 As shown, in this embodiment, a leakage hole 102 is provided on the middle plate 11, and the setting of the leakage hole 102 can facilitate the discharge of liquid flowing to the middle plate 11. Moreover, a harness through hole 103 is provided on the connecting plate 112 and the middle plate 11, so that the harness can be arranged easily.

[0048] It can be understood here that in addition to being set on both the connecting plate 112 and the middle plate body 11, the wiring harness via 103 can also be set only on the connecting plate 112, or only on the middle plate body 11, or a part of the wiring harness via 103 is set on the connecting plate 112, and the other part is set on the middle plate body 11. The wiring harness via 103 can be specifically set according to the actual layout requirements of the wiring harness.

[0049] In this embodiment, at least one of the side panels 12 and the middle panel 11 is provided with a first flange 101. The provision of the first flange 101 is conducive to improving the structural strength and rigidity of the main support 1, thereby improving the structural strength of the mounting bracket assembly. Preferably, in this embodiment, the first flange 101 is provided on both sides of the side panels 12 and the middle panel 11, so that the structural strength and rigidity of the main support 1 itself can be further improved, and the structural strength of the mounting bracket assembly can be further improved.

[0050] Moreover, a first reinforcing rib 110 is also provided on the middle plate 11, and the first reinforcing rib 110 extends along the width direction of the vehicle. The provision of the first reinforcing rib 110 is also beneficial to improving the structural strength and rigidity of the main bracket 1 itself, and combined with the provision of the first flange 101, the structural strength of the mounting bracket assembly can be further improved, and the mode of the auxiliary instrument panel frame 3 can be further improved.

[0051] Still viewing Figure 3 and Figure 4 In this embodiment, the auxiliary bracket 2 on each side includes an upper plate 201 and a lower plate 202, wherein the upper plate 201 is connected to the side plate 12. The lower plate 202 is bent relative to the upper plate 201 toward a side away from the side plate 12. The third connecting portion 300 includes a side plane provided on one side of the lower plate 202, and the lower plate 202 is welded to the vehicle body floor through the side plane.

[0052] At this time, the auxiliary bracket 2 is formed of an upper plate 201 and a lower plate 202 connected in a bent shape, which is convenient for simultaneous connection with the auxiliary instrument panel frame 3 and the vehicle body floor. The third connecting portion 300 is set as a side plane welded to the vehicle body floor, which not only provides a stable and reliable support for the auxiliary bracket 2 by using the vehicle body floor, but also facilitates the setting of multiple welding points, thereby improving the connection reliability between the auxiliary bracket 2 and the vehicle body floor.

[0053] As a preferred embodiment, corresponding to the above-mentioned first connection part 100, that is, corresponding to the first connection hole 120, in this embodiment, a through hole is also provided on the upper plate body 201, and the upper plate body 201 and the side plate body 12 are connected to the auxiliary instrument panel frame 3 through a connecting piece that passes through the corresponding first connection hole 120 and the through hole. In this case, the upper plate body 201, the side plate body 12 and the auxiliary instrument panel frame 3 are connected together by the same connecting piece, which has a simple structure, is easy to process, and is relatively easy to assemble and disassemble.

[0054] It is worth noting that, in addition to being connected together by the same connecting piece, the upper plate 201, the side plate 12 and the auxiliary instrument panel frame 3 can also be provided with the upper plate 201 welded to the side plate 12, and then connected to the auxiliary instrument panel frame 3 through the side plate 12, thereby realizing the connection of the upper plate 201, the side plate 12 and the auxiliary instrument panel frame 3.

[0055] As a preferred embodiment, in this embodiment, there are multiple first connection holes 120 on each side plate 12, and the multiple first connection holes 120 on the same side plate 12 are arranged at intervals in the longitudinal direction of the vehicle, and the through holes, the connecting members and the first connection holes 120 are arranged in a one-to-one correspondence. At this time, the first connection holes 120, the through holes and the connecting members are arranged in multiples, and the first connection holes 120 on the same side plate 12 are arranged at intervals in the longitudinal direction of the vehicle, which can improve the connection reliability of the upper plate 201, the side plate 12 and the auxiliary instrument panel frame 3.

[0056] Continue to view Figure 3 and Figure 4 As shown, in this embodiment, a second flange 21 is provided on the side of at least one of the upper plate 201 and the lower plate 202. The provision of the second flange 21 can improve the structural strength and rigidity of the auxiliary bracket 2 itself, thereby improving the structural strength of the mounting bracket assembly. Preferably, in this embodiment, a second flange 21 is provided on each side of the upper plate 201 and the lower plate 202, so that the structural strength and rigidity of the auxiliary bracket 2 itself can be further improved, thereby improving the structural strength of the mounting bracket assembly, and further benefiting from improving the modality of the auxiliary instrument panel frame 3.

[0057] In addition, in this embodiment, at least one of the upper plate 201 and the lower plate 202 is also provided with a second reinforcing rib 22, and the second reinforcing rib 22 extends along the height direction of the vehicle. The provision of the second reinforcing rib 22 can also improve the structural strength of the auxiliary bracket 2 and the structural strength of the mounting bracket assembly. At this time, combined with the provision of the second flange 21, the structural strength of the auxiliary bracket 2 and the structural strength of the mounting bracket assembly can be further improved, and further, it is beneficial to improve the modality of the auxiliary instrument panel frame.

[0058] In addition, as a preferred embodiment, in this embodiment, a first positioning portion 104 is also provided on the main bracket 1, and the first positioning portion 104 is used to define the installation position of the main bracket 1 on the vehicle body floor. A second positioning portion 20 is also provided on the auxiliary bracket 2, and the second positioning portion 20 is used to define the installation position of the auxiliary bracket 2 on the vehicle body floor. Among them, the first positioning portion 104 and the second positioning portion 20 preferably adopt a positioning hole structure, which has a simple structure and is conducive to improving assembly efficiency and assembly quality.

[0059] It should be noted that the second connection part 200 and the third connection parts 300 on both sides of this embodiment are preferably connected to the middle channel of the vehicle body floor. At this time, also as a preferred embodiment, in this embodiment, the position of the third connection part 300 in the height direction of the vehicle is lower than the position of the second connection part 200 in the height direction of the vehicle. In this way, a triangular structure is formed between the third connection parts 300 on both sides and the second connection part 200 in the middle. On the one hand, the structural stability of the triangle can be used to better control the deformation of the auxiliary instrument panel in the width direction of the vehicle. On the other hand, it is also convenient to match the structure of the middle channel on the vehicle body floor, thereby utilizing the structural strength of the middle channel to improve the overall strength and rigidity of the mounting bracket assembly.

[0060] The mounting bracket assembly of the present embodiment improves the connection structure with the auxiliary instrument panel frame 3 and the vehicle body floor, so that a triangular support structure is formed between the third connection part 300 on the auxiliary bracket 2 and the first connection part 100 and the second connection part 200 on either side of the main bracket 1. The high strength of the triangle is utilized to improve the structural strength and rigidity of the mounting bracket, thereby enabling the auxiliary instrument panel frame 3 to be firmly and reliably fixed to the vehicle body floor and effectively ensuring the modality of the auxiliary instrument panel frame.
