As shown in fig. 1 to 4, a mounting frame 100 applied to an electric vehicle according to some embodiments of the present disclosure is provided, and the mounting frame 100 is used to mount a compressor 200 of the electric vehicle on a motor 300 of the electric vehicle. The structure of the mounting frame 100 includes a first bracket 110, a second bracket 120, and a plurality of vibration isolation bushings 130. The first bracket 110 is configured to be fixedly coupled to the motor 300 by a plurality of first fasteners 140. The second bracket 120 is fixedly coupled to the first bracket 110 by a plurality of second fasteners 150 and encloses an installation space for accommodating the compressor 200 with the first bracket 110. The plurality of vibration isolation bushes 130 are fitted into the first bracket 110 and the second bracket 120 with axes parallel, wherein the compressor 200 is configured to be fixedly connected to the first bracket 110 and the second bracket 120 in an installation space by a plurality of third fasteners 160 respectively provided in the plurality of vibration isolation bushes 130.

In some embodiments, when the compressor 200 is mounted on the motor 300 using the mounting frame 100 described above, first, the first bracket 110 is fixed to the motor 300 by the plurality of first fasteners 140; then, the compressor 200 is initially positioned on the first bracket 110, and the compressor 200 is fixedly connected with the first bracket 110 and the second bracket 120 through a plurality of third fasteners 160; the second bracket 120 is then fixedly coupled to the first bracket 110 by a plurality of second fasteners 150.

The mounting frame 100 adopting the embodiment of the present disclosure for mounting the compressor 200 has the following technical advantages:

the compressor 200 is located in the installation space surrounded by the first bracket 110 and the second bracket 120, and the first bracket 110 and the second bracket 120 can protect the compressor 200;

the plurality of vibration isolating bushings 130 are embedded in the first bracket 110 and the second bracket 120, and the vibration isolating structure (e.g., vibration isolating rubber) thereof can attenuate the vibration transmission between the third fastener 160 and the first bracket 110 and the second bracket 120, that is, the vibration transmission between the compressor 200 and the motor 300;

since the plurality of vibration isolating bushings 130 are fitted to the first bracket 110 and the second bracket 120 with axes parallel to each other, the mounting bracket 100 can relatively uniformly bear the weight of the compressor 200 at both sides of the compressor 200, so that the torque output of the compressor 200 is smooth, which is advantageous in reducing the working vibration of the compressor 200.

Therefore, the mounting bracket 100 of the embodiment of the present disclosure is used to mount the compressor 200, so that NVH performance of the electric vehicle can be effectively improved, thereby improving riding comfort of passengers in the vehicle.

The plurality of third fasteners 160 are three sets of first bolt assemblies. The first bracket 110 and the second bracket 120 relatively uniformly bear the weight of the compressor 200 at both sides of the compressor 200, which is advantageous in that the compressor 200 operates smoothly and reliably.

Referring to fig. 1 and 4, in this embodiment, the axes of the three vibration isolation bushes 130 are respectively located approximately at three apexes of an equilateral triangle S, so that the mount 100 is more stable to the support of the compressor 200 based on the stability of the equilateral triangle.

In this way, service and maintenance is facilitated on the plurality of vibration isolator bushings 130 and the plurality of third fasteners 160 therein.

In the disclosed embodiment, the first, second and third fasteners 140, 150, 160 may be screw or bolt assemblies, respectively. The number of the first, second and third fasteners 140, 150 and 160, respectively, is not limited and may be set according to the fastening requirements.

As shown in fig. 1 and 4, in some embodiments, four sets of second bolt assemblies (i.e., the first fasteners 140) are provided, and the first bracket 110 is provided with four first mounting holes 141 corresponding to the four sets of second bolt assemblies. The four first mounting holes 141 may be distributed at regular intervals on the first bracket 110.
