Technical Field

[0001] The utility model relates to the technical field of extended-range hybrid vehicles, in particular to a low-temperature radiator combined bracket of an extended-range hybrid vehicle. Background Art

[0002] The function of the automobile radiator is to store water and dissipate heat. For existing extended-range hybrid vehicles, the temperature of the high-temperature coolant differs greatly from that of the low-temperature coolant. Therefore, the existing extended-range hybrid vehicles need to design two cooling systems to cool the high-temperature part and the low-temperature part respectively. Due to the structural and space limitations of existing extended-range hybrid vehicles, the bracket of the low-temperature radiator mostly adopts an integral bracket, which has a relatively complex structure and is heavy and inconvenient to install. The low-temperature radiator needs to dissipate heat during the driving of the vehicle. The heat dissipation effect of the low-temperature radiator of the existing extended-range hybrid vehicles is not good.

[0003] Therefore, the utility model provides a low-temperature radiator assembly bracket for an extended-range hybrid vehicle. Summary of the invention

[0004] The utility model provides a low-temperature radiator combined bracket for a range-extended hybrid vehicle, which solves the problems that the existing low-temperature radiator bracket is mainly an integral bracket, has a relatively complex and heavy structure, is inconvenient to fix and install, and has a poor heat dissipation effect.

[0005] In order to solve the technical problem, the utility model adopts the following technical solution:

[0006] A low-temperature radiator combination bracket for an extended-range hybrid vehicle comprises a mounting bracket, a front transition bracket, and a rear transition bracket. The mounting bracket is a frame structure with a right-angle trapezoidal bottom. A vehicle frame connecting plate, a front transition bracket connecting plate, and a rear transition bracket connecting plate are provided at the upper end of the connection of the frame. The front transition bracket is fixed to the front transition bracket connecting plate by a first bolt, and the rear transition bracket is fixed to the rear transition bracket connecting plate by a first bolt.

[0007] The front transition bracket is lower than the rear transition bracket. When in use, the low-temperature radiator is installed on the front transition bracket and the rear transition bracket, so that the installed low-temperature radiator maintains an angle of 20º-30º with the frame, so that the low-temperature radiator has a certain windward area during vehicle driving.

[0008] Furthermore, a reinforcing plate is welded to the bottom frame of the mounting bracket, and a reinforcing plate is welded to the long side of the bottom frame.

[0009] Furthermore, the front transition bracket and the rear transition bracket are both bent parts, and reinforcing ribs are provided at the bending parts.

[0010] Furthermore, the front transition bracket and the rear transition bracket are both provided with weight-reducing holes.

[0011] Furthermore, the protruding portions of the connecting edges at the front ends of the front transition bracket and the rear transition bracket are provided with mounting holes.

[0012] Furthermore, the connecting plate, the rear end of the front transition bracket, and the rear end of the rear transition bracket are all provided with connecting holes.

[0013] The beneficial effects of the utility model are:

[0014] The bottom of the mounting bracket of the utility model is a right-angled trapezoidal frame structure, and the frame structure can achieve the effect of weight reduction. Two frame connecting plates, a front transition bracket connecting plate, and a rear transition bracket connecting plate are arranged at the vertices of the right-angled trapezoid. The front transition bracket connecting plate and the rear transition bracket connecting plate of the mounting bracket are provided with a front transition bracket and a rear transition bracket. The split arrangement is convenient for installation. The different heights of the front transition bracket and the rear transition bracket facilitate the installation of the low-temperature radiator, so that a certain angle is formed between the mounting bracket and the front transition bracket and the rear transition bracket after installation. The rear end of the front transition bracket is a long plate, which can better and more conveniently install the low-temperature radiator, and ensure that the installed low-temperature radiator maintains an angle of 20º-30º with the frame. The angle allows the low-temperature radiator to better contact the wind during the driving of the vehicle, thereby dissipating heat and achieving a better cooling effect. The utility model has a simple and light structure, a convenient processing process, and convenient layout and installation. BRIEF DESCRIPTION OF THE DRAWINGS
