Description

Technical Field

[0001] The present application relates to the field of motor installation, and more specifically, to a motor bracket and a new energy vehicle. Background Art

[0002] The motor and reducer are arranged on the frame, and the structure is a mid-mounted rear-wheel drive. The distance between the frames on both sides is far. In this case, there are two traditional layout methods. One of them is to directly make the suspension on the frame, fix the motor to the suspension through a longer bracket, and then fix it to the frame through the suspension. This method will cause the motor to be suspended in the air, and the requirements for the bracket will be very high.

[0003] After the motor is installed on the frame, since the existing frame structure lacks a heat dissipation structure for the motor, it is easy for the motor to accumulate heat generated by its operation when it works for a long time. The heat cannot be dissipated in time, which will affect the service life of the motor. For this reason, we propose a motor bracket and a new energy vehicle. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a motor bracket and a new energy vehicle, aiming to improve the problem of the lack of heat dissipation structure in the existing vehicle frame.

[0006] In a specific embodiment, the bottom bracket includes a first U-shaped frame and a second U-shaped frame, both ends of the first U-shaped frame and the second U-shaped frame are connected to the frame, and the lower cover is connected to the first U-shaped frame and the second U-shaped frame.

[0007] In a specific implementation manner, two first connecting frames are installed on the first U-shaped frame, two supporting legs are installed on the motor body, and the two supporting legs are respectively connected to the two first connecting frames with bolts.

[0009] In a specific embodiment, the heat dissipation assembly includes a top plate bolted to the top of the frame, a frame plate is connected through the top plate, a heat dissipation fan is installed in the frame plate, and the upper cover is fixedly installed on the bottom of the top plate and is connected to the frame plate.

[0010] In a specific embodiment, the lower cover body and the upper cover body are both arranged in a semi-circular shape, and are provided with gas flow grooves inside, so that air can flow inside the lower cover body and the upper cover body.

[0011] In a specific embodiment, the lower cover body and the upper cover body are closed to form an annular cover, which is sleeved on the motor and has a gap between the annular cover and the outer wall of the motor body.

[0012] In a second aspect, the present application further provides a new energy vehicle, comprising

[0013] The motor bracket mentioned above.

[0014] The beneficial effects of the present application are as follows: a bottom bracket is installed on the vehicle frame, a motor body is installed on the bottom bracket, a lower cover is installed on the bottom bracket, a heat dissipation assembly is installed on the top of the vehicle body, an upper cover is installed on the bottom of the heat dissipation assembly, and the upper cover can be sleeved on the motor after the upper cover and the lower cover are closed. At the same time, there is a gap between the upper cover and the outer wall of the motor body, so that when the heat dissipation assembly is working, air is transported to the upper cover and the inside of the lower cover, so that the air flows outward along the above-mentioned gap, so that the airflow flows on the outer wall of the motor to achieve a good heat dissipation effect.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1-6 The present application provides a motor bracket, including a frame 10, a detachable bottom bracket 20 is installed on the frame 10, a detachable motor body 30 is installed on the top of the bottom bracket 20, and a lower cover 40 located below the motor body 30 is also installed on the top of the bottom bracket 20, a heat dissipation component 50 is detachably connected to the top of the frame 10, and an upper cover 60 closed with the lower cover 40 is installed at the bottom of the heat dissipation component 50. Specifically, the upper cover 60 and the lower cover 40 will be covered on the motor body 30 after closing, and there is a gap between the upper cover 60 and the outer wall of the motor body 30, so that the heat dissipation component 50 blows air into the upper cover 60 and the lower cover 40, so that the air in the upper cover 60 and the lower cover 40 flows quickly, so that the air is blown out from the gap, so that the air flows through the outer wall of the motor body 30, so as to achieve the purpose of heat dissipation of the motor body 30.

[0025] See also Figure 4 The bottom bracket 20 includes a first U-shaped frame 210 and a second U-shaped frame 220. Both ends of the first U-shaped frame 210 and the second U-shaped frame 220 are connected to the frame 10. The lower cover 40 is connected to the first U-shaped frame 210 and the second U-shaped frame 220. When set, the first U-shaped frame 210 and the second U-shaped frame 220 are connected to the frame 10 through a bolt structure, and the lower cover 40 is fixedly connected to the first U-shaped frame 210 and the second U-shaped frame 220.

[0026] See also Figure 3 and 4Two first connecting frames 230 are installed on the first U-shaped frame 210, and two supporting legs 310 are installed on the motor body 30. The two supporting legs 310 are respectively bolted to the two first connecting frames 230. In the specific setting, the supporting legs 310 are bolted to the first connecting frames 230, so that the supporting legs 310 can be separated from the first connecting frames 230, which is convenient for disassembly and assembly of the motor body 30.

[0027] See also Figure 3 and 4 Two second connecting frames 240 are installed on the second U-shaped frame 220, and a third U-shaped frame 320 is installed at the bottom of the motor body 30. The two ends of the third U-shaped frame 320 are respectively bolted to the two second connecting frames 240. Similarly, the third U-shaped frame 320 is screwed to the second connecting frame 240 to facilitate disassembly and assembly of the motor body 30.

[0028] See also Figure 4 The heat dissipation assembly 50 includes a top plate 510 bolted to the top of the frame 10, a frame plate 520 is connected through the top plate 510, a heat dissipation fan 530 is installed in the frame plate 520, and the upper cover body 60 is fixedly installed on the bottom of the top plate 510 and is connected to the frame plate 520. It should be noted that the specific installation structure of the heat dissipation fan 530 is the existing technology. When the heat dissipation fan 530 is working, the air in the frame plate 520 will flow quickly, thereby making the air in the upper cover body 60 and the lower cover body 40 flow quickly, and further making the air blow out through the gap and flow through the outer wall of the motor body 30 to achieve the purpose of heat dissipation of the motor body 30.

[0029] See also Figure 3 The lower cover body 40 and the upper cover body 60 are both semi-circular in shape, and are provided with gas flow grooves therein to allow air to flow in the lower cover body 40 and the upper cover body 60. When the lower cover body 40 and the upper cover body 60 are closed, an annular cover is formed, which is sleeved on the motor body 30, and there is a gap between the annular cover and the outer wall of the motor body 30. In the specific setting, there is a gap between the annular cover and the outer wall of the motor body 30, and the gap is annular in shape, so that air is blown out from the gap and flows in a direction perpendicular to the gap, thereby allowing the air to flow through the surface of the motor body 30 to take away the heat on the outer wall of the motor body 30.

[0031] The motor bracket mentioned above.

[0032] When the motor bracket and the new energy vehicle are in operation: the motor body 30 is installed on the bottom bracket 20, and the top plate 510 is installed on the frame 10, so that the upper cover 60 and the lower cover 40 are closed and sleeved on the motor body 30. When the motor body 30 is working, the heat dissipation fan 530 will be started at the same time, and the heat dissipation fan 530 makes the air in the frame plate 520 flow into the upper cover 60 and the lower cover 40, so that the air is blown out from the gap between the upper cover 60 and the lower cover 40 and the outer wall of the motor body 30, so that the air quickly flows through the outer wall of the motor body 30, thereby achieving the purpose of heat dissipation of the motor body 30.

[0033] It should be noted that the specific models and specifications of the frame 10, the motor body 30 and the cooling fan 530 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
