DETAILED DESCRIPTION

[0022] like Figure 1-3 As shown, the utility model provides an integrated high and low voltage accessory mounting bracket for new energy vehicles, comprising: a truss frame 10 and a double tube beam support 20 rigidly connected to the bottom of the truss frame 10, the truss frame 10 is divided into a bottom layer 11 and a top layer 12, for separately mounting high voltage accessories and low voltage accessories; both ends of the double tube beam support 20 are rigidly connected to the vehicle frame 30 respectively.

[0023] Compared with the prior art, the mounting bracket provided by the utility model can integrate the high-pressure accessories and the low-pressure accessories respectively at the double-layer mounting position formed by the truss frame 10. On the truss frame 10 of a certain height, the high-pressure accessories and the low-pressure accessories can also be arranged more compactly. The high-pressure accessories and the low-pressure accessories are arranged on the same truss frame 10. During installation, the whole can be assembled in place at one time, and multiple assembly mounting brackets can be eliminated, thereby realizing the integration of vehicle modules, reducing weight and cost, and improving the loading efficiency of the whole vehicle. The double-tube beam support 20 can improve the torsional resistance of the frame 30.

[0024] It should be noted that the high-voltage accessories include but are not limited to an air-conditioning compressor 43 , an electric water pump 44 and an electric steering oil pump 45 , and the low-voltage accessories include but are not limited to a low-voltage battery module 41 and an all-in-one controller 42 .

[0025] In this embodiment, a support plate 13 is provided on the top of the truss frame 10 , and the support plate 13 is fixedly connected to the low-voltage battery module 41 .

[0026] Specifically, the support plate 13 can be made of steel, aluminum alloy or engineering plastic, and is fixedly connected to the square tube that constitutes the truss frame 10 by bolts, serving as a supporting and mounting platform for the low-voltage battery module 41. The support plate 13 is fixedly connected to the low-voltage battery module 41 by multiple bolts.

[0027] Furthermore, the front and rear ends of the support plate 13 are provided with warped edges 131, and a plurality of mounting holes 132 are opened on the warped edges 131. The sides of the low-voltage battery module 41 are provided with corresponding screw holes, and the fastening bolts pass through the mounting holes 132 to be fixedly connected to the low-voltage battery module 41. With such a configuration, the warped edges 131 can realize the side fixation of the low-voltage battery module 41, which is easier to operate than bottom fixation, and also has a limiting function.

[0028] In this embodiment, the bottom layer 11 and the top layer 12 of the truss frame 10 are both rectangular frames formed by welding and / or bolting square tubes or square bars, and the bottom layer 11 and the top layer 12 are fixed by welding through a plurality of square tube columns. At least two transverse C-shaped support beams 121 are bolted or welded on one side of the support plate 13 on the top layer 12 for mounting the all-in-one controller 42.

[0029] In this embodiment, a plurality of mounting beams 111 are rigidly connected to the bottom layer 11 of the truss frame 10 , and each mounting beam 111 is provided with a plurality of mounting holes 112 for passing fastening bolts to fix the air conditioning compressor 43 and the electric steering oil pump 45 .

[0030] Specifically, the mounting beam 111 is made of square tubes or angle steels, and both ends of a plurality of parallel mounting beams 111 are welded and fixed to the square tubes constituting the truss frame 10, and the mounting beams 111 are only arranged at a position close to one end of the truss frame 10, so that high-pressure accessories such as the air-conditioning compressor 43 and the electric steering oil pump 45 can be arranged more centrally.

[0031] In one embodiment, the end of the bottom layer 11 of the truss frame 10 is rigidly connected to a base 113 , and the base 113 is fastened to the electric water pump 44 by bolts.

[0032] Specifically, the base 113 is made of two steel plates with bent ends, and are respectively welded to the two sides of the square tube placed horizontally at the end of the truss frame 10, so as to reasonably utilize the limited space and set the electric water pump 44 at the end, which is easier to connect with the water pipe and the water pipe is not easy to interfere with other electrical equipment. A plurality of through holes are opened on the base 113, and the electric water pump 44 is placed on the base 113, so that the electric water pump 44 is fixed to the base 113 by bolts and nuts, which is convenient for installation and disassembly.

[0033] In this embodiment, the double-tube beam support 20 includes a lower support 1 21 and a lower support 2 22. The lower support 2 22 is located below the high-pressure accessory, and the middle part of the lower support 2 2 is bent downward. In this way, by designing a reasonable spacing between the lower support 1 21 and the lower support 2 2, as well as a specific fixed position on the vehicle frame 30, compared with a support of a general continuous structure, each accessory can be installed from the bottom of the truss frame 10, and the installation of the double-tube beam support 20 itself is also much easier, which is conducive to improving assembly efficiency and lightweight design. In addition, the end where the high-pressure accessory is usually installed is relatively heavy, and the lower support 2 22 needs to be set below the high-pressure accessory to play a better supporting role, and the sinking bending design of the middle part of the lower support 2 22 ensures the installation space below the high-pressure accessory.

[0034] In one embodiment, the lower support member 21 includes a straight rod 211, two support plates 212 that are dispersedly arranged and rigidly connected to the straight rod 211, two baffles 213 that are respectively connected to the outer sides of the two support plates 212, and two fixing plates 214 that are respectively rigidly connected to the outer sides of the two baffles 213; the two support plates 212 are fixedly connected to the truss frame 10 by bolts, the two baffles 213 are respectively attached to the two sides of the truss frame 10, and the two fixing plates 214 are fixedly connected to the frame 30 by bolts.

[0035] Specifically, the straight rod 211 is made of a hollow steel pipe or a solid steel pipe, the support plate 212 is made of a bent steel plate, and the bottom end of the support plate 212 is attached to the surface of the straight rod 211 and welded and fixed, the two baffles 213 are made of steel plates, the ends of the straight rod 211 pass through the baffles 213 and are welded and fixed, the inner side of the baffle 213 is welded and fixed to the outer end of the support plate 212, and the fixing plate 214 is welded and fixed to the straight rod 211 and the baffles 213. In this way, the connection structure at both ends of the lower support member 21 is ensured to have high mechanical strength.

[0036] In one embodiment, the lower support member 22 includes a bent rod 221, two support plates 222 dispersedly arranged and rigidly connected to the straight rod 211, and two fixed plates 223 rigidly connected to both ends of the bent rod 221; the two support plates 222 are fixedly connected to the truss frame 10 by bolts, and the two fixed plates 223 are fixedly connected to the frame 30 by bolts.

[0037] Specifically, the bending rod 221 is made of a hollow steel pipe or a solid steel pipe, the two support plates 222 are made of bent steel plates, and the two ends of the support plates 222 are attached to the surface of the bending rod 221 and welded and fixed, thereby ensuring the stability of the connection of the support plates 222. The fixing plate 223 is a rectangular steel plate with multiple through holes, and the two ends of the bending rod 221 pass through the fixing plate 223 and the end faces do not exceed.

[0038] The utility model provides a vehicle chassis, including the above-mentioned integrated high and low voltage accessory mounting bracket for new energy vehicles. The mounting bracket can realize the integration of vehicle modules, reduce weight and cost, and improve the vehicle loading efficiency.
