Electric vehicle power component

This creation relates to the technical field of an electric motor vehicle, and in particular to the power assembly of an electric motor vehicle.

At present, the electric motor car is mainly powered by a motor and transmitted to the wheels through a transmission to drive the vehicle forward. In order to increase the torque of the motor or reduce the speed, the motor is usually combined with the transmission of the reduction gear set. Based on the workload, operating speed, and the need to maintain the motor operating at optimum operating efficiency, the motor and reduction gear set must be properly matched to achieve better operating characteristics. In addition, the motor needs to be paired with a suitable controller (device). The controller (device) is used to detect the output speed of the motor, and the instantaneous transfer control signal controls the rotational speed of the motor.

Traditionally, the motor, the reduction gear set and the controller are independent components or devices, so the total volume of each component or device is large, and the motor vehicle needs to have a large installation space for the components or devices to be smooth. Installation location.

Furthermore, the components or devices need to be connected by wires (wires) for detection and control. However, the separate components and devices form the wires exposed, which in turn causes the wires to significantly interfere with the installation behavior.

The present invention is to solve the shortcomings of the excessive size of the power components of the conventional electric motor vehicle and the obvious exposure of the wire.

The purpose of the present invention is to provide a power assembly for an electric motor vehicle, which has an electric motor, a driven tooth and a control element integrated in the same body, thereby forming a three-machine integrated body to reduce the volume and enabling the wire to be integrated into the body. , reduce interference during installation.

In order to achieve the above object and effect, the power component disclosed in the present invention comprises a body having a base, the base having a partition layer on one side, a side of the partition layer being a first group space, and the other side a second set of space; an electric motor is in the body, the electric motor has a power output shaft, the output shaft is combined with a transmission gear, the transmission gear is located in the first group space; a driven gear Mounted inside the body, the driven gear is axially mounted with a gear shaft, the driven gear is located in the first group space and engages the transmission gear, one end of the gear shaft passes out of the body; and a control component Installed in the second group of matching spaces and electrically connected to the electric motor.

In this way, the electric motor, the transmission gear and the control element are mounted in the body to form a three-machine integrated form, so that the overall volume can be significantly reduced. In addition, the control element is electrically connected to the electric motor, so that the control element and the electric motor are mounted in the same body, and a wire for connecting the control element and the electric motor can be integrated into the body, thereby reducing the The wire interferes with the assembly line of the power assembly.

One end of the output shaft 42 passes through the first shaft hole 32.

The driven gear 50 disclosed in this embodiment is axially mounted with a gear shaft 52. The driven gear 50 is located in the second gear chamber 30 of the first assembly space 24 and engages the transmission gear 44. Further, one end of the gear shaft 52 passes through the second shaft hole 34, so that the gear shaft 52 passes through. The bottom of the base 20, that is, one end of the gear shaft 52 passes out of the body 10.

Referring to Figures 2, 4, and 5, the body 10 disclosed in this embodiment includes a coupling base 60 in addition to the base 20. The joint 60 is assembled on one side of the base 20 and corresponds to the first set of spaces 24. The joint 60 has a consistent perforation 62. One end of the electric motor 40 passes through the through hole 62 of the joint 60. A cover 70 is mounted on the joint 60 and is used to close the through hole 62 such that one end of the electric motor 50 is housed inside the cover 70. In addition, one end of the driven gear 50 can be pivotally disposed on the joint 60.

Referring to Figures 2 and 6, the example also includes a control element 80. The control element 80 is a combination of a circuit board and an electronic component or the like. The control element 80 is mounted on the second assembly space 26 and electrically connected to the electric motor 40. In addition, a cover plate 90 is disposed on one side of the base 20 for closing the second assembly space 26.

Referring to FIG. 7 , since one end of the output shaft 42 of the electric motor 40 passes through the first shaft hole 32 and is located in the second assembly space 26 , a shaft cover 92 may be disposed in the second assembly space 26 . And one end of the output shaft 42 of the electric motor 40 is pivotally mounted on the shaft cover 92. The control element 80 can be located on one side of the shaft cover 92. The two ends of the output shaft 42 can be matched with the bearing 100 mounted in the cover 70 and the bearing 102 mounted in the first shaft hole 32, so that the transmission gear 44 can be stably rotated. Furthermore, the two ends of the gear shaft 52 of the driven gear 50 can be coupled with a bearing 104 mounted in the second hole 34 and a bearing 106 mounted on the coupling seat 60, so that the driven gear 50 is driven by the transmission gear 44. Can produce a stable rotation. Further, one end of the gear shaft 52 passes through the body 10, so that a pulley 110 can be mounted on a portion of the gear shaft 52 that passes through the body 10, thereby transmitting the torque generated by the electric motor 40.

In this embodiment, the electric motor 40, the transmission gear 50, and the control element 80 are mounted in the body 10 to form a three-machine integrated structure, so that the overall volume can be significantly reduced. In addition, the control element 80 is electrically connected to the electric motor 40. Therefore, the control element 80 and the electric motor 40 are mounted in the same body 10, and the wire connecting the control element 80 and the electric motor 40 can be used ( Not shown) is integrated inside the body 10. Since the wire is not exposed, when the electric component is mounted, the interference generated by the wire can be reduced, and the installation of the power component is quicker and more convenient.
