Description

Technical Field

[0001] The utility model belongs to the technical field of motor heat dissipation, and in particular relates to a new energy vehicle motor with a heat dissipation function. Background Art

[0002] New energy vehicle motors are mainly divided into three types: DC motors, asynchronous motors, and permanent magnet synchronous motors. They are one of the three major components of new energy vehicles.

[0003] When the motor is used for a long time, it will generate a lot of heat. If it cannot be discharged in time, the internal temperature of the motor will rise, and finally the service life of the motor will be affected. The motor of new energy vehicles is directly installed on the wheel drive rod, so that when the motor is moving, the wind generated by driving can be used to cool the motor. However, when the car is driving, the wind is mostly concentrated in the front and bottom of the motor, resulting in uneven heat dissipation of the motor, which affects its service life. Therefore, in order to dissipate heat evenly, an additional air-cooled or liquid-cooled radiator is set for auxiliary heat dissipation. However, this heat dissipation method requires additional consumption of automobile energy and may cause the overall structure of the motor to be too large, thereby affecting its structural stability and resulting in certain limitations in its installation position.

[0004] Therefore, how to provide a new energy vehicle motor with heat dissipation function is a problem that technical personnel in this field need to solve urgently. Utility Model Content

[0005] The purpose of the utility model is to provide a new energy automobile motor with a heat dissipation function, aiming to solve the problems mentioned in the background technology.

[0006] The utility model is implemented as follows: a new energy automobile motor with heat dissipation function, comprising:

[0007] Mounting plate;

[0008] A motor body, wherein the motor body is fixedly mounted on the bottom of the mounting plate;

[0009] A front cover and a rear cover, wherein the front cover and the rear cover are symmetrically arranged at the front and rear ends of the motor body;

[0010] A heat dissipation structure, which is arranged on the front side of the front end cover and in the motor body to cool the motor body;

[0011] The heat dissipation structure includes a frame, a spiral groove and a spiral plate. The frame is fixedly installed on the edge of the front side of the motor body. The spiral groove is opened in the inner wall of the edge of the motor body and connected to the outside world. The spiral plate is fixedly installed on the front side of the front end cover to guide the wind.

[0012] Preferably, the rear end of the motor body is also provided with a plug-in structure, which includes an insert block and a spring. A lifting groove is provided at the top of the rear end of the motor body, and a slot is provided at the top of the rear end cover. The insert block is movably arranged in the lifting groove and the front end cover, and the spring is fixedly installed on the top of the front end of the insert block and fixedly connected to the top of the lifting groove.

[0013] Preferably, a rotor is disposed inside the motor body, and a front end of the rotor passes through a middle portion of the front end cover.

[0014] Preferably, the diameters of the front cover and the rear cover are the same as the inner diameter of the motor body.

[0015] Preferably, the guiding direction of the spiral plate is the position of the front end of the spiral groove.

[0016] Compared with the prior art, the beneficial effect of the utility model is that when in use, by setting up the heat dissipation structure, when the car is driving, the wind generated by the oncoming wind will be guided by the heat dissipation structure, concentrated through the inner wall of the motor body, and exchanged with the heat generated inside, so that the heat of the motor body can be reduced, and because of the use of natural wind sources, the consumption of additional energy is avoided.

[0033] In the embodiment of the utility model, when in use, the motor body 2 is mounted on the drive shaft with the mounting plate 1, and then as the vehicle moves, the wind is guided by the heat dissipation structure, the motor body 2 will contact the wind, and then the wind will hit the front side of the motor body 2, and then the wind will be concentrated into the spiral groove 3 under the guidance of the spiral plate 5, and then the wind will move in a spiral in the inner wall of the motor body 2. Then the heat is discharged from the rear end of the motor body 2, and finally the heat in the motor body 2 is evenly reduced, and the consumption of extra energy is avoided; by setting the frame 4, the wind will not run out from the edge of the front side of the motor body 2, so that the wind can be concentrated into the spiral groove 3 under the guidance of the spiral plate 5, so that the heat in the motor body 2 is guided out;

[0034] By setting up the heat dissipation structure, when the car is driving, the wind generated by the oncoming wind will be guided by the heat dissipation structure, concentrated through the inner wall of the motor body 2, and exchanged with the heat generated inside it, so that the heat of the motor body 2 can be reduced, and because the natural wind source is used, the consumption of additional energy is avoided.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment of the utility model, the rear end of the motor body 2 is also provided with a plug-in structure, the plug-in structure includes an insert block 10 and a spring 11, a lifting groove 9 is opened at the top of the rear end of the motor body 2, a slot 12 is opened at the top of the rear end cover 6, the insert block 10 is movably arranged in the lifting groove 9 and the front end cover 8, and the spring 11 is fixedly installed at the top of the front end of the insert block 10 and fixedly connected to the top of the lifting groove 9.

[0036] In the embodiment of the utility model, when the motor body 2 needs to be opened for maintenance during use, the insert block 10 is pulled upward so that the lower end of the insert block 10 is removed from the slot 12 at the top of the rear end cover 6, so that the rear end cover 6 can be taken out;

[0037] By providing the plug-in structure, it is convenient to inspect and maintain the internal structure of the motor body 2.

[0038] like Figure 2 As shown, as a preferred embodiment of the utility model, a rotor 7 is disposed inside the motor body 2 , and the front end of the rotor 7 passes through the middle of the front end cover 8 .

[0039] In the embodiment of the utility model, when in use, a rotor 7 is provided inside the motor body 2, and the front end of the rotor 7 penetrates the middle part of the front end cover 8, so as to facilitate driving the corresponding structure to rotate.

[0040] like Figure 2As shown, as a preferred embodiment of the present invention, the diameters of the front cover 8 and the rear cover 6 are the same as the inner diameter of the motor body 2 .

[0041] In the embodiment of the utility model, when in use, the installation of the front end cover 8 and the rear end cover 6 is facilitated by making the diameter value of the front end cover 8 and the rear end cover 6 the same as the inner diameter value of the motor body 2 .

When in use, the motor body 2 is mounted on the drive shaft using the mounting plate 1, and then the rotor 7 is started, thereby driving the drive shaft to rotate, so that the automobile moves;

[0045] When the car is moving, the motor body 2 will contact the wind, and then the wind will hit the front side of the motor body 2. Then, due to the presence of the frame 4, the wind will not escape from the edge of the front side of the motor body 2. Then, under the guidance of the spiral plate 5, the wind will be concentrated and enter the spiral groove 3.

[0046] When the wind enters the spiral groove 3, the wind moves in a spiral in the inner wall of the motor body 2. Thus, the wind indirectly contacts the heat at the upper and lower ends of the motor body 2, thereby generating heat exchange, and then is discharged from the rear end of the motor body 2, ultimately reducing the heat in the motor body 2 evenly and avoiding the consumption of extra energy;

[0047] When the motor body 2 needs to be opened for maintenance, the insert block 10 is pulled upward so that the lower end of the insert block 10 is removed from the slot 12 at the top of the rear end cover 6, so that the rear end cover 6 can be taken out, so that the internal structure of the motor body 2 can be inspected and maintained.
