[0030] See also Figure 1 to Figure 2As shown, the mounting bracket includes a first bracket 2 and a second bracket 4, the first bracket 2 includes a longitudinal rod 21, the high-voltage auxiliary drive controller 1 is fixed to the longitudinal rod 21, the longitudinal rod 21 surrounds a first cavity 210, the second bracket 4 includes a top plate 41 and a side plate 42 connected to the top plate 41, the top plate 41 is adjacent to the side plate 42, the second bracket 4 is located below the first bracket 2, the top plate 41 is fixed to the first bracket 2, and the side plate 42 is fixed to the frame 3. The mounting bracket of the present application includes a split first bracket 2 and a second bracket 4, which is convenient for processing and molding.

[0031] The longitudinal bars 21 of the first bracket 2 form a first cavity 210 , which can enhance the overall bearing capacity and anti-deformation performance of the first bracket 2 .

[0032] In some embodiments, the first bracket 2 and the second bracket 4 are made of aluminum. Aluminum has a low density and can effectively reduce the weight of the entire mounting bracket, which is beneficial to controlling the quality indicators of the entire vehicle and improving fuel efficiency and power performance. Aluminum has high plasticity and easy processing properties, which is beneficial to realizing complex bracket structure design and improving manufacturing flexibility. Aluminum can be recycled and reprocessed and can be recycled about 20 times, which effectively extends the service life of aluminum and increases economic benefits.

[0033] The first bracket 2 and the second bracket 4 are made of aluminum, including pure aluminum and aluminum alloy.

[0034] In some embodiments, the first bracket 2 and the second bracket 4 may also be made of carbon fiber reinforced composite material.

[0035] In some embodiments, the first mounting plate 31 includes: a main body 311 and a first bending portion 312 and a second bending portion 313 extending from both ends of the main body 311 toward the direction of the first bracket 2. The first bending portion 312 and the second bending portion 313 are arranged opposite to each other. Along the length direction of the main body 311, the first bending portion 312 is located above the second bending portion 313. The second bending portion 313 abuts against the side plate 42 of the second bracket 4 and is fixed to the side plate 42. The first mounting plate 31 is C-shaped as a whole and is open toward the direction of the first bracket 2.

[0036] The second bending portion 313 and the side plate 42 may be fixed by a fourth fixing member (not shown).

[0037] The fourth fixing member may be a bolt or a screw.

[0038] In some embodiments, the second mounting plate 32 has the same shape as the first mounting plate 31, is C-shaped as a whole and is open toward the first bracket 2. The first mounting plate 31 and the second mounting plate 32 are disposed opposite to each other.

[0039] See also Figures 2 to 4As shown, the longitudinal rod 21 includes an upper side wall 211 and a lower side wall 212 that are arranged opposite to each other, and a connecting wall 213 connecting the upper side wall 211 and the lower side wall 212. The upper side wall 211, the lower side wall 212 and the connecting wall 213 enclose a first cavity 210. The high-voltage auxiliary drive controller 1 is fixed to the upper side wall 211, and the top plate 41 is fixed to the lower side wall 212. In this embodiment, the number of connecting walls 213 is 2, and the two connecting walls 213 are arranged opposite to each other. The upper side wall 211, the lower side wall 212 and a pair of connecting walls 213 enclose a first cavity 210, which can effectively resist external loads and improve the deformation resistance of the mounting bracket. The high-voltage auxiliary drive controller 1 is directly fixed on the upper side wall 211 to ensure the stability of the installation.

[0040] In some embodiments, a connecting wall 213 may be used to connect the upper side wall 211 and the lower side wall 212 to form a "U"-shaped semi-open cavity or an "I"-shaped semi-open cavity.

[0041] In some embodiments, the connecting wall 213 and the upper side wall 211 and the lower side wall 212 may be designed to be separated and fixed together, for example, by bolts, snaps, welding or other connection methods.

[0042] The upper side wall 211 is provided with a first hole 2111, and the lower side wall 212 is provided with a second hole 2121. The second hole 2121 is larger than the first hole 2111. The second hole 2121 is used for passing tools, and the first hole 2111 is used for passing a first fixing member. The first fixing member is used to fix the high-voltage auxiliary drive controller 1 to the upper side wall 211. The larger second hole 2121 can facilitate the passage of a sleeve tool to install and disassemble the high-voltage auxiliary drive controller 1. The first fixing member installs the high-voltage auxiliary drive controller 1 on the upper side wall 211, which can ensure that the high-voltage auxiliary drive controller 1 is firmly fixed on the upper side wall 211 to avoid accidental falling off.

[0043] The first fixing member may be a bolt or a screw, etc. The first fixing member may pass through the first hole 2111 and then be fixed with a nut, or may be threadedly connected with the upper side wall 211 .

[0044] In some embodiments, the first hole 2111 and the second hole 2121 may also be designed to have the same size, and the first fixing member is fixed with a nut or threadedly connected with the lower side wall 212 after passing through the first hole 2111 and the second hole 2121 .

[0045] In some embodiments, a detachable first fixing member such as an elastic retaining ring or a buckle may be used to replace the traditional bolt connection.

[0046] In some embodiments, a plurality of first holes 2111 and second holes 2121 may be provided on the upper side wall 211 and the lower side wall 212 along the length direction of the longitudinal rod 21 to further improve the installation firmness of the controller.

[0047] In some embodiments, a guide groove or a guide hole is provided around the second hole 2121 to guide the insertion of the sleeve tool, thereby improving the accuracy and efficiency of assembly.

[0048] The lower side wall 212 is provided with a first mounting hole 2122 and a second mounting hole 2123. The line connecting the center of the first mounting hole 2122 and the center of the second mounting hole 2123 is defined as L1. The central axis of the lower side wall 212 is positioned as L2. L1 and L2 are not perpendicular and parallel. The first mounting hole 2122 and the second mounting hole 2123 form a double oblique hole. The design of the double oblique hole reduces the installation space 33 of the longitudinal rod 21 in the length direction. At the same time, the double oblique hole solves the problem of easy loosening of the bolt due to the torsion of the frame 3 when a single hole is used.

[0049] In some embodiments, the first mounting hole 2122 and the second mounting hole 2123 may be disposed along the length direction of the longitudinal rod 21 , or may be disposed along the width direction of the longitudinal rod 21 .

[0050] Optionally, only the first mounting hole 2122 or the second mounting hole 2123 may be provided on the lower side wall 212 , which may also meet the fixing requirements.

[0051] In some embodiments, the first mounting hole 2122 and the second mounting hole 2123 are designed to be in the shape of an ellipse or an elongated hole instead of a traditional round hole, so as to increase the installation tolerance and improve the convenience of assembly.

[0052] See also Figure 5 As shown, the top plate 41 is provided with a third mounting hole 411 and a fourth mounting hole 412, the first mounting hole 2122 and the third mounting hole 411 are used for the second fixing member 44 to pass through, so as to fix the second bracket 4 and the first bracket 2, and the second mounting hole 2123 and the fourth mounting hole 412 are used for the third fixing member 45 to pass through, so as to fix the second bracket 4 and the first bracket 2. The second bracket 4 further includes a pair of connecting plates 43, which are respectively connected to the top plate 41 and the side plate 42 and are arranged opposite to each other, and the connecting plates 43 are triangular in shape.

[0053] In some embodiments, the top plate 41 is perpendicular to the side plate 42 and combined with the triangular connecting plate 43 to form a three-dimensional support. This structural layout can effectively resist external loads and improve the overall anti-deformation ability. At the same time, less material is used, which is conducive to the lightweight installation bracket.

[0054] In some embodiments, the second fixing member 44 and the third fixing member 45 may be bolts or screws.

[0055] In some embodiments, the first bracket 2 and the second bracket 4 as well as the second bracket 4 and the frame 3 may be fixed by welding or snapping.

[0056] See also Figures 6 to 8 As shown, the mounting bracket includes a harness bracket 5 fixed on the connecting wall 213, and the harness bracket 5 is used to fix the vehicle's pipeline 6. The integration and fixation of the pipeline 6 by the harness bracket 5 can prevent the pipeline 6 from shaking or loosening during driving, thereby enhancing the overall stability.

[0057] In some embodiments, a plurality of harness brackets 5 may be disposed on the connecting wall 213 to form an array distribution, which can meet more complex pipeline layout requirements and improve overall adaptability.

[0058] The mounting bracket includes a rivet nut 214 fixed on the connecting wall 213, which is used to fix the wiring harness bracket 5 on the connecting wall 213. The installation of the rivet nut 214 only requires reserving holes on the connecting wall 213, and then squeezing and fixing it with a special tool, without relying on traditional thread matching, thereby improving assembly efficiency; at the same time, the welding process is omitted; furthermore, the rivet nut 214 occupies a small space and is light in weight, which is conducive to optimizing the space layout and weight control of the entire vehicle.

[0059] In some embodiments, the harness bracket 5 can be fixed to the connecting wall 213 by welding or buckling.

[0060] The mounting bracket includes a plurality of rivet nuts 214 , which are arranged in sequence along the length direction of the connecting wall 213 .

[0061] In some embodiments, instead of using the rivet nut 214 , a detachable wiring harness bracket 5 may be used, which cooperates with the connecting wall 213 via buckles, bolts or other connectors.

[0062] See also Figures 2 to 4 and Figures 9 and 10 As shown, the mounting bracket includes at least one pair of longitudinal bars 21 and at least one cross bar 22. The opposite ends of the cross bar 22 are respectively connected to the pair of longitudinal bars 21. The cross bar 22 encloses a second cavity 220. The cross bar 22 is provided with a fixing hole 221 for installing the line clip 7. The line clip 7 is used to fix the pipeline 6 of the vehicle. The cross section of the longitudinal bar 21 is the same as the cross section of the cross bar 22.

[0063] In some implementations, the end of the line card 7 is inserted into the fixing hole 221 to form an interference fit to fix the line card 7 .

[0064] In some embodiments, the first bracket 2 is formed by welding extruded aluminum profiles, and the cross-section shape of the cross bar 22 and the longitudinal bar 21 is the same, and can be processed using the same extrusion die.

[0065] In this embodiment, there are two cross bars 22, which are arranged opposite to each other, and the two ends of the cross bars 22 are respectively connected to the longitudinal bars 21. The combination design of the longitudinal bars 21 and the cross bars 22 forms a relatively strong "well"-shaped skeleton structure, which can effectively withstand various external loads during driving.

[0066] In some embodiments, the pipeline 6 is various lines such as radiator soft / hard pipe, high-voltage auxiliary drive controller 1 DC input line, electric air conditioner compressor line, DC charging socket line, chassis low-voltage wiring harness, etc.

[0067] In some embodiments, the cross bar 22 is designed to be detachable and connected to the longitudinal bar 21 by means of bolts or buckles.

[0068] In some embodiments, a plurality of fixing holes 221 are provided on the crossbar 22 to form an array distribution.

[0069] In some embodiments, a “U”-shaped or “C”-shaped open crossbar 22 design may be directly adopted to replace the original closed cavity structure to introduce the pipeline 6 and arrange it in the crossbar 22 .

[0070] The embodiment of the present application also provides a vehicle, which includes a frame 3, a high-voltage auxiliary drive controller 1 and the above-mentioned mounting bracket. The mounting bracket is installed at the lower rear side of the cab of the vehicle. The frame 3 includes a first mounting plate 31 and a second mounting plate 32 arranged opposite to each other, and the first mounting plate 31 and the second mounting plate 32 enclose an installation space 33. The high-voltage auxiliary drive controller 1 fixed with the first bracket 2 and the second bracket 4 enters the installation space 33 from the bottom of the frame 3, and the plurality of second brackets 4 are respectively fixed to the first mounting plate 31 or the second mounting plate 32.

[0071] In some embodiments, the mounting bracket includes a plurality of second brackets 4 .

[0072] In this embodiment, the number of the second brackets 4 is four, which are respectively disposed at both ends of a pair of longitudinal rods 21 and fixed to the vehicle frame 3, thereby improving the load-bearing capacity and deformation resistance of the entire mounting bracket system.

[0073] The first bracket 2 and the second bracket 4 of the present application are designed to be split, which is convenient for processing and forming; the lightweight design reduces the weight of the overall mounting bracket by 40%, and the aluminum alloy material is recyclable, which is in line with the "dual carbon" strategy and increases economic benefits. At the same time, multiple pipelines 6 are integrated into one and installed on the mounting bracket, which is easy to assemble.
