DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] like Figure 1 As shown, a specific embodiment of the utility model provides a new energy vehicle motor suspension assembly, which can improve the stability of the vehicle motor installation and has a better seismic isolation effect; it specifically includes a suspension beam 100, and upwardly inclined mounting parts 200 are provided on both sides of the suspension beam 100; the upper end of the suspension beam 100 is provided with a mounting seat 300 arranged symmetrically on the left and right, and a motor frame 400 for mounting the motor is fixed on the upper end of the mounting seat 300, and shock-absorbing pads in contact with the motor mounting position are provided on both sides of the motor frame 400; a lateral support frame 600 is hinged on the inner side of the mounting part 200 of the suspension beam 100, and the end of the lateral support frame 600 can be fixedly connected to the outer side of the motor.

[0021] like Figure 1 As shown, through the above-mentioned arrangement, the motor frame 400 arranged at the upper end of the suspension beam 100 in this embodiment can fix the motor assembly, and the two sides of the motor frame 400 have a shock-absorbing pad structure directly connected to the motor structure, which can buffer and absorb the shock during the operation of the motor, and the motor frame 400 is fixed to the inner side of the suspension beam 100 through the mounting seat 300, and the lateral support frame 600 located on the inner side of the mounting portion 200 further fixes the two sides of the motor. The mounting seat 300 and the lateral support frame 600 constitute a three-point installation, which can effectively improve the stability of the suspension beam 100 to the motor installed on the bracket, as well as the ability to withstand stress and torque; the device can also flexibly adjust the installation position and the size of the motor frame 400 according to the size of the motor, thereby improving the versatility of the suspension beam 100 and achieving higher installation reliability. At the same time, it can solve the problems of vehicle resonance and motor howling caused by poor vibration isolation rate of traditional horizontal suspension, thereby greatly improving the noise level and ride comfort of the vehicle.

[0022] like Figure 1 As shown, when the motor is installed on the suspension beam 100 and then assembled on the vehicle as a whole, a large stress will be generated during the operation of the motor. In this embodiment, a stress opening 110 arranged at intervals and penetrating the suspension beam 100 is provided on the inner side of the suspension beam 100, and a reinforcing rib 700 is provided in the stress opening 110. The stress opening 110 can eliminate the stress generated by the overall structure, and at the same time, the rigidity and strength of the overall structure are ensured under the action of the reinforcing rib 700. In order to improve the protection effect of the motor, a detachable isolation guard plate 800 is provided at the lower end of the suspension beam 100 in this embodiment. The isolation guard plate 800 protects the bottom of the suspension beam 100 to prevent the motor from being damaged.

[0023] As mentioned above, the mounting platform is used to fix the motor frame 400 on the inner side of the suspension beam 100. In this embodiment, connecting flanges 900 are provided at the upper and lower ends of the mounting base. The connecting flanges 900 can ensure the stability of the connection between the motor frame 400 and the suspension beam 100, and at the same time, it is more convenient to remove the motor frame from the suspension beam 100 when replacing the motor frame.

[0024] like Figure 1 As shown, the suspension beam 100 with the motor installed needs to be assembled on the vehicle longitudinal beam for fixing. In this embodiment, a connecting platform 1000 connected to the vehicle longitudinal beam is provided at the upper end of the mounting portion 200, and a seismic isolation pad is provided at the upper end of the connecting platform 1000. After the connecting platform 1000 is fixed to the vehicle longitudinal beam, the entire suspension beam 100 structure is further seismically isolated through the shock-absorbing pad to reduce vibration and noise. At the same time, in this embodiment, multiple stress grooves 210 are also provided on the inner side of the mounting portion 200 to reduce the stress of the suspension beam 100.

[0025] like Figure 1 As shown, the present embodiment further optimizes the structure of the motor frame 400, and a receiving groove 410 for receiving the bottom of the motor is provided at the upper end of the motor frame 400, and motor plates 420 for fixing the motor are provided on both sides of the receiving groove 410. In this way, when the motor is fixed, it is connected to the motor plate 420, and the shock-absorbing pad is arranged on the motor plate 420 for shock absorption, and the present embodiment also provides a heat dissipation groove 430 at the bottom of the receiving groove 410 of the motor frame 400. The heat generated by the motor can be dissipated from the outside of the motor frame 400 as soon as possible, thereby reducing the temperature of the motor corresponding to the motor frame 400 area.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
