Problems solved by technology

[0003] When the automobile motor works for a long time, it will consume too much energy, which will cause the heat of the motor to increase and cause damage to the motor. Most of the existing motors use water cooling to cool down the motor, and the coolant fluidity in the motor is small. As a result, the heat dissipation effect is not good, and the car will shake during driving, which will vibrate with the motor and cause damage to the motor. Therefore, we propose a new type of drive motor for electric vehicles

Embodiment 1

[0034] refer to Figure 1-3 , a new drive motor for electric vehicles, including a protective shell 1 and a motor body 2, the inner side wall of the protective shell 1 is connected with a symmetrically distributed baffle 6, the opposite side of the baffle 6 is connected with a shock-absorbing splint 5, and the protective shell 1 The inner side wall is connected with a piston cylinder 7, the top of the piston cylinder 7 is slidably connected with a piston rod 9, the end of the piston rod 9 away from the piston cylinder 7 is connected with the damping splint 5 through the baffle plate 6, and the piston cylinder 7 is connected on the side wall near the bottom end. There is a water pipe 8, a heat exchange jacket 3 is connected to the outer wall of the motor body 2, the motor body 2 is connected with the damping splint 5 through the heat exchange jacket 3, and the end of the water pipe 8 away from the piston cylinder 7 is communicated with the inner cavity of the heat exchange jacke...

Embodiment 2

[0036] refer to Figure 4, a new driving motor for electric vehicles, which is basically the same as Embodiment 1, the difference is that the stirring assembly includes stirring blades 15, and the stirring blades 15 are connected with the outer wall of the first drive shaft 201 placed inside the heat exchange jacket 3, and the first A drive shaft 201 is placed on the inner outer wall of the protective shell 1 and is connected to the first driving gear 13. The top end of the baffle plate 6 is connected to a support plate 16. The support plate 16 is rotatably connected to a first rotating shaft 17, and the first rotating shaft 17 is away from the support plate. One end of 16 is connected with the first driven gear 14, the first driven gear 14 is meshed with the first driving gear 13, the rotation of the first drive shaft 201 drives the first driving gear 13 connected to it to rotate, and the first driving gear 13 drives The first driven gear 14 meshing with it rotates, and the f...

Embodiment 3

[0038] refer to Figure 5 , a new type of drive motor for electric vehicles, basically the same as Embodiment 2, the difference is that the shock-absorbing pad 4 is connected to the top of the shock-absorbing splint 5, and the shock-absorbing pad 4 is connected to the inner wall of the bottom of the shock-absorbing splint 5. The first spring 501 .

[0039] The first spring 501 is a butterfly spring.

[0040] When the motor body 2 squeezes the shock-absorbing plate 5, the shock-absorbing washer 4 connected to the shock-absorbing plate 5 will sag and squeeze the first spring 501 connected to it. plate 4, so as to give the motor body 2 a buffer force to make it shake slightly, and the butterfly spring makes the buffer of the motor body 2 more stable.

Abstract

The invention discloses a novel drive motor for an electric vehicle, and belongs to the technical field of electric vehicles. The novel drive motor for the electric vehicle comprises a protective caseand a motor body. One end of a piston rod away from a piston cylinder penetrates through a baffle plate to be connected with a damping clamp plate. A heat exchange jacket is connected on the outer wall of the motor body. A stirring component is connected on the outer wall, which is arranged in the heat exchange jacket, of a first drive shaft. A heat dissipation component is connected on one end,which is arranged in the protective case, of the first drive shaft. When the motor body generates heat, the first drive shaft drives the stirring component to stir the coolant inside the heat exchangejacket, the first drive shaft also drives the heat dissipation component connected with the first drive shaft to work to dissipate the heat from the heat exchange jacket and the motor body. When themotor body sloshes, the damping clamp plate gives it a buffering force so that the piston cylinder continuously draws out and discharges the coolant inside the heat exchange jacket to speed up the heat exchange of the coolant so that the cooling and damping efficiency of the motor body can be improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a novel drive motor for electric vehicles. Background technique [0002] According to the requirements of the vehicle demand parameters, combined with the kinematics principles and basic theoretical knowledge of pure electric vehicles, the parameters of the power system are calculated, the mechanical model of the pure electric vehicle is established, the structure, layout and control strategy of the power system are determined, and the power system is proposed. The matching design method strives to maximize the working efficiency of the drive motor while ensuring the speed and torque requirements. [0003] When the car motor works for a long time, the energy consumption of the motor will increase and cause damage to the motor. Most of the existing motors use water cooling to cool the motor, while the coolant in the motor has less fluidity. As a result, the heat dissipa...
