Abstract
Description
Technical Field
[0001] The present invention relates to a bracket, in particular to a multifunctional bracket assembly for a new energy electric commercial vehicle, belonging to the technical field of new energy electric commercial vehicles. Background Art
[0002] The frame of new energy electric commercial vehicles is composed of the front section with equal cross-section and the middle and rear section with equal cross-section. For the specific structure, please refer to Figure 8 , the size of the front section of the equal-section frame assembly is slightly less accurate than that of the middle and rear sections. The main reason is that the processing technology of the equal-section frame with a wide front and a narrow rear is difficult, and there are phenomena such as material bending and stress release. Therefore, when the frame is "wide at the front and narrow at the rear", it is not easy to control the accuracy of the front section of the frame. When assembling other parts of the frame, the lack of accuracy will cause offset holes and misplaced holes. The solution is on-site hole expansion and milling, etc., especially the electric drive controller bracket assembly, power battery high-voltage junction box bracket, all-in-one controller bracket, drive motor controller bracket and other devices often encounter such problems during assembly. The traditional way is to add an auxiliary installation process beam to ensure the span size of the longitudinal beam of the frame with a wide front and a narrow rear section. The process beam is removed after the relevant vehicle components are assembled.
[0003] The disadvantage of the existing process beam is that the process beam is easy to use, but there is a bottleneck in the sequence of parts and components during the assembly of the whole vehicle. If there is an obstruction between the process beam and the installation component in the upper and lower positions, it is impossible to assemble according to the original process sequence.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0023] Embodiments of the present invention: Figure 1-Figure 7 As shown, a multifunctional bracket assembly for a new energy electric commercial vehicle includes a main support frame 1, a lower support frame 2 and an upper support frame 3. The lower support frame 2 is fixedly connected to the bottom of the main support frame 1 through a plurality of first steel pipes 4, and the upper support frame 3 is fixedly connected to the top of the main support frame 1 through a plurality of second steel pipes 5. An all-in-one controller assembly 6 and a drive motor controller assembly 7 are both installed on the main support frame 1, and a power battery high-voltage junction box assembly 8 is installed on the upper support frame 3.
[0024] In this embodiment, the lower support frame 2 is fixedly connected to the main support frame 1 through four first steel pipes 4, and the four first steel pipes 4 are respectively welded and fixed to the four corners of the lower support frame 2. The upper support frame 3 is fixedly connected to the main support frame 1 through four second steel pipes 5, and the four second steel pipes 5 are respectively welded and fixed to the four corners of the upper support frame 3.
[0025] Specifically, the main support frame 1 includes a first cross bar 9, a second cross bar 10, a third cross bar 11 and a fourth cross bar 12. Longitudinal beam connecting holes 13 are provided at both ends of the first cross bar 9, the second cross bar 10, the third cross bar 11 and the fourth cross bar 12. The first cross bar 9 is fixedly connected to the second cross bar 10 through two first longitudinal bars 14, the second cross bar 10 is fixedly connected to the third cross bar 11 through two second longitudinal bars 15, and the third cross bar 11 is fixedly connected to the fourth cross bar 12 through two third longitudinal bars 16.
[0026] The present application is fixedly connected to the left longitudinal beam 32 and the right longitudinal beam 31 of the frame by the first cross bar 9, the second cross bar 10, the third cross bar 11 and the fourth cross bar 12 through anti-loosening bolts. The first cross bar 9 is the same length as the second cross bar 10, and the third cross bar 11 is the same length as the fourth cross bar 12. The present application is installed on a front wide and rear narrow frame assembly. The left longitudinal beam 32 and the right longitudinal beam 31 of the frame assembly are both composed of a longitudinal beam front section, a transition section and a longitudinal beam rear section. The distance between the longitudinal beam front section of the left longitudinal beam 32 and the longitudinal beam front section of the right longitudinal beam 31 is greater than the distance between the longitudinal beam rear section of the left longitudinal beam 32 and the longitudinal beam rear section of the right longitudinal beam 31. The first cross bar 9 and the second cross bar 10 are both fixedly connected to the front sections of the left longitudinal beam 32 and the right longitudinal beam 31 , the third cross bar 11 is fixedly connected to the transition sections of the left longitudinal beam 32 and the right longitudinal beam 31 , and the fourth cross bar 12 is fixedly connected to the rear sections of the left longitudinal beam 32 and the right longitudinal beam 31 .
[0027] By setting the first cross bar 9, the second cross bar 10, the third cross bar 11 and the fourth cross bar 12, the spacing limit of the front section, transition section and rear section of the left longitudinal beam 32 and the right longitudinal beam 31 is achieved, so that the present application plays the role of the process beam in the prior art, so that the holes on the left longitudinal beam 32 and the right longitudinal beam 31 are in accurate positions, thereby facilitating the installation of various devices.
[0028] The first cross bar 9, the second cross bar 10, the third cross bar 11, the fourth cross bar 12, the first longitudinal bar 14, the second longitudinal bar 15 and the third longitudinal bar 16 are preferably made of steel pipes with a rectangular cross section. They are arranged in the same plane and fixedly connected by welding.
[0029] The area surrounded by the first cross bar 9, the second cross bar 10 and the two first longitudinal bars 14 is used to install the all-in-one controller assembly 6. Two mounting holes are respectively provided on the two first longitudinal bars 14. The all-in-one controller assembly 6 is fixedly connected to the two first longitudinal bars 14 by four bolt assemblies in total. The grounding wire of the all-in-one controller assembly 6 is fixedly connected to the left longitudinal beam 32 by a bolt assembly.
[0030] Furthermore, the second cross bar 10 and the third cross bar 11 are also fixedly connected by a first support rod 17, the first support rod 17 is located between the two second longitudinal rods 15, and the first support rod 17 is parallel to the second longitudinal rods 15; the third cross bar 11 and the fourth cross bar 12 are also fixedly connected by a second support rod 18, and the second support rod 18 and the first support rod 17 are arranged on the same straight line.
[0031] Existing new energy electric commercial vehicles are usually equipped with two drive motor controller assemblies 7, so it is necessary to reserve installation positions for the two drive motor controller assemblies, and the area surrounded by the second cross bar 10, the first support bar 17, the second support bar 18, the fourth cross bar 12, the third longitudinal bar 16 on the right side, and the second longitudinal bar 15 on the right side is used to install the two drive motor controller assemblies 7. The first support bar 17, the second support bar 18, the third longitudinal bar 16 on the right side, and the second longitudinal bar 15 on the right side are provided with installation holes.
[0032] The area between the first support rod 17 and the second longitudinal rod 15 on the left is the avoidance area. Similarly, the area between the second support rod 18 and the third longitudinal rod 16 on the left is the avoidance area. By setting the avoidance area, sufficient layout space can be reserved for high-voltage wires.
[0033] Preferably, a harness fixing beam 33 is welded and fixed between the second support rod 18 and the third longitudinal rod 16 on the right side, and two harness fixing brackets 34 are welded to the bottom of the harness fixing beam 33. The two harness fixing brackets 34 are used to fix the harnesses on the two drive motor controller assemblies 7. The lower edges of the two harness fixing brackets 34 have a flange structure, and the strength of the bracket and the flatness of the mounting surface are ensured by the flange structure.
[0034] Furthermore, a first wire harness limiting plate 19 and a second wire harness limiting plate 20 are fixedly provided on the side of the first cross bar 9 away from the second cross bar 10 , and a third wire harness limiting plate 21 is fixedly provided on the side of the second cross bar 10 facing the third cross bar 11 .
[0035] The first wire harness limiting plate 19, the second wire harness limiting plate 20 and the third wire harness limiting plate 21 are all provided with circular holes for the wire harness to pass through, and the four corners of the first wire harness limiting plate 19, the second wire harness limiting plate 20 and the third wire harness limiting plate 21 are all provided with through holes with smaller diameters for the passing of cable ties to fix the wire harnesses.
[0036] The two side edges perpendicular to the first cross bar 9 on the first wire harness limiting plate 19 and the second wire harness limiting plate 20 are folded downward to form flanged portions, and the two side edges perpendicular to the second cross bar 10 on the third wire harness limiting plate 21 are folded upward to form flanged portions. The setting of the flanged portions can effectively improve the structural strength of the first wire harness limiting plate 19, the second wire harness limiting plate 20 and the third wire harness limiting plate 21, and ensure the horizontality of their installation surfaces.
[0037] The provision of the first wire harness limiting plate 19 , the second wire harness limiting plate 20 and the third wire harness limiting plate 21 can make the wire harness more orderly and prevent the wire harness from being messily interwoven.
[0038] Furthermore, the lower support frame 2 includes a fifth cross bar 22, a sixth cross bar 23 and three fourth longitudinal bars 24. The fifth cross bar 22 is located directly below the second cross bar 10, and the sixth cross bar 23 is located directly below the third cross bar 11. The fifth cross bar 22 is fixedly connected to the sixth cross bar 23 through the three fourth longitudinal bars 24. A fourth wire harness limiting plate 25 is fixedly provided on the fifth cross bar 22, and the fourth wire harness limiting plate 25 is located directly below the third wire harness limiting plate 21.
[0039] The lower support frame 2 is mainly used to support and fix various wiring harnesses. The fourth wiring harness limiting plate 25 also has a circular hole. The fourth wiring harness limiting plate 25 is arranged directly below the third wiring harness limiting plate 21. The two cooperate to limit the same set of wiring harnesses. The side of the fourth wiring harness limiting plate 25 also has a flange structure.
[0040] Furthermore, the upper support frame 3 includes a seventh cross bar 26, an eighth cross bar 27, a fifth longitudinal bar 28 and a sixth longitudinal bar 29. The seventh cross bar 26 is located directly above the second cross bar 10, and the eighth cross bar 27 is located directly above the fourth cross bar 12. One end of the seventh cross bar 26 is fixedly connected to one end of the eighth cross bar 27 via the fifth longitudinal bar 28, and the other end of the seventh cross bar 26 is fixedly connected to the other end of the eighth cross bar 27 via the sixth longitudinal bar 29.
[0041] The seventh crossbar 26 and the eighth crossbar 27 are both steel pipes with rectangular cross-sections. The fifth longitudinal bar 28 and the sixth longitudinal bar 29 are preferably made of L-shaped bent high-strength steel. The power battery high-voltage junction box assembly 8 is fixed between the fifth longitudinal bar 28 and the sixth longitudinal bar 29 by bolts. The power battery high-voltage junction box assembly 8 is fixed between the fifth longitudinal bar 28 and the sixth longitudinal bar 29 so that the high-voltage wiring harness thereon has a larger layout space, so that the high-voltage wiring harness can be conveniently extended toward the rear of the vehicle to connect with the power battery pack 35 installed on the left longitudinal beam 32 and the right longitudinal beam 31 of the frame.
[0042] Furthermore, a concave mounting plate 30 is fixedly disposed on the fifth longitudinal rod 28, and the bottom edge of the concave mounting plate 30 is fixedly connected to the third longitudinal rod 16 located directly below the fifth longitudinal rod 28. The concave mounting plate 30 is used to fix the charging socket box.
[0043] In the present application, the “concave”-shaped mounting plate 30 is disposed below the upper support frame 3 , so that an ultra-short path connection is achieved between the charging socket box and the power battery high-voltage junction box assembly 8 .
[0044] The present application integrates the process beam, all-in-one controller assembly mounting bracket, drive motor controller assembly mounting bracket and power battery high-voltage junction box assembly mounting bracket in the prior art, reducing the overall occupied space. It not only plays the role of the process beam, but also centrally installs the all-in-one controller assembly 6, the drive motor controller assembly 7 and the power battery high-voltage junction box assembly 8, shortening the length of the wiring harness connection between them and reducing costs.
[0045] When faced with the spatial layout of flat-head electric heavy trucks and long-head electric heavy trucks, other technical solutions in the current industry often lack systematic optimization design, resulting in loose layout of various components, occupying a large amount of unnecessary space, affecting the space utilization and functional expansion of the vehicle. However, this application achieves efficient layout with minimal space occupation through careful design and layout optimization, accurately matches the mainstream development trend of the industry in the future, constructs the most ideal design architecture, provides an excellent example for vehicle system integration, and leads the new direction of industry space layout.
[0046] The present application fixes the power battery high-voltage junction box assembly 8 on the upper support frame 3, so that the high-voltage electrical lines of the power battery high-voltage junction box assembly 8 run smoothly and can extend backward in a straight line without interference to connect with the power battery pack 35.
[0047] Since the present application replaces the traditional process beam, the steps of dismantling the process beam are reduced, and the problem of material waste caused by the process beam in the prior art being unable to be used after being recycled is also solved.
[0048] The present application enables the wiring harness to be effectively fixed by setting the first wiring harness limiting plate 19, the second wiring harness limiting plate 20, the third wiring harness limiting plate 21, the fourth longitudinal rod 24, the fourth wiring harness limiting plate 25 and the wiring harness fixing bracket 34, thereby effectively improving the overall neatness and safety performance.
[0049] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
