Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, where the described embodiments are only exemplary implementations of the present application, and not all implementations. Those skilled in the art can combine the embodiments of the present application to obtain other embodiments without inventive faculty, and such embodiments are also within the scope of the present application.
In an electric vehicle, a motor controller is used for converting electric energy stored in a power battery into electric energy required by a driving motor according to instructions such as gears, throttle, brake and the like, so as to control the starting operation of the electric vehicle and the like.
The main loop of the motor controller mainly controls the closing or opening of the contactor to realize the power supply control of the motor. When the main circuit opens the contactor to discharge, the energy stored by the coil needs to be dissipated by the discharge resistor.
At present, the connection modes of components such as a contactor, a discharge resistor and the like in the motor controller lead to low integration level and compact structure of the motor controller.
Based on this, the embodiment of the application provides a contactor so that the structural compactness of the motor controller can be improved when the motor controller is applied to the contactor. In particular implementations, embodiments of the present application provide a contactor that may include: a contactor body and a discharge resistor. The discharging resistor is arranged on the contactor body, and the contactor body is electrically connected with the discharging resistor. That is, in the contactor provided by the present application, the discharge resistor is integrally mounted with the contactor body, and the discharge resistor is included in the contactor. Thus, when the contactor is subsequently applied to the motor controller, the structural compactness of the motor controller can be improved due to the fact that the discharging resistor and the contactor body are integrally arranged.
The embodiment of the application provides a contactor, which can comprise a contactor body and a discharge resistor, wherein the discharge resistor is arranged on the contactor body, and the contactor body is electrically connected with the discharge resistor, namely, circuit connection can be realized between the contactor body and the discharge resistor.
The contactor body may include a contactor core, and the discharge resistor may be electrically connected to the contactor body through an electrical connection between the discharge resistor and the contactor core.
Optionally, the contactor body may also include a housing, i.e., the contactor body may be composed of a contactor core and a housing. According to the above embodiment, the discharge resistor may be mounted to the contactor body. In one possible implementation, the discharge resistor may be mounted inside the housing, i.e. the discharge resistor is mounted inside the contactor body. By the mode, the original contactor body and the discharge resistor need to occupy the space of the motor controller, so that the space of only one contactor body is reduced, and the structural compactness of the motor controller can be improved.
The discharging resistor comprises a first connecting terminal and a second connecting terminal, and the contactor core comprises a third connecting terminal and a fourth connecting terminal. When the discharge resistor is mounted inside the contactor housing, the electrical connection of the discharge resistor with the contactor core may be achieved by one of the first connection terminal and the second connection terminal of the discharge resistor being electrically connectable with one of the third connection terminal and the fourth connection terminal of the contactor core, that is, with a part of the third connection terminal or the fourth connection terminal inside the housing. The remaining other one of the first connection terminal and the second connection terminal of the discharge resistor is led out of the housing for connection of an external device. The connection terminals of the discharging resistor and the connection terminals of the contactor core body can be electrically connected through copper bars or OT terminal wire harnesses and the like.
Referring specifically to fig. 1, fig. 1 is a schematic structural diagram of a contactor according to an embodiment of the present application. The contactor body includes a contactor core including a third connection terminal 101 and a fourth connection terminal 102, and a housing. As can be seen from fig. 1, the housing of the contactor body comprises an axial end face, wherein parts of the third connection terminal 101 and parts of the fourth connection terminal 102 protrude from the axial end face. The discharge resistor includes a first connection terminal and a second connection terminal, one of which 103 is led out of the housing for connection of an external device.
Through the contactor that this application above-mentioned embodiment provided, can install the discharge resistor in the inside of contactor body, when subsequently being applied to motor controller with this contactor, reduced the volume that motor controller internal device occupy, improved motor controller's integrated level and compact structure.
In addition, the embodiment of the application also provides another structure of the contactor, namely another mode of installing the discharge resistor on the contactor body.
As can be seen from the above embodiments, the contactor body may include a contactor core and a housing. In one possible implementation, the discharge resistor may be mounted outside the housing, i.e. the discharge resistor is mounted outside the contactor body, and then the contactor is composed of the discharge resistor and the contactor body. Compared with the prior art, the discharging resistor of the motor controller and the contactor body are two independent devices, redundant space exists between the discharging resistor and the contactor body, and redundant space of the motor controller is occupied. When the discharging resistor is arranged outside the shell, the occupation of redundant space can be reduced, the discharging resistor and the contactor body are arranged into a whole to form a contactor, and when the contactor is applied to the motor controller, the occupation of the internal space of the motor controller can be reduced, and the structural compactness of the motor controller is improved.
With this structure, the discharge resistor and the contactor core can be electrically connected in such a manner that the discharge resistor includes the first connection terminal and the second connection terminal, and the contactor core includes the third connection terminal and the fourth connection terminal. One of the first connection terminal and the second connection terminal of the discharge resistor is electrically connected with one of the third connection terminal and the fourth connection terminal of the contactor core.
In the above embodiments, the connection manner of the discharge resistor and the contactor core and the mounting manner of the contactor body are described when the contactor body includes one contactor core, and in one possible implementation, the contactor body may include a first contactor core and a second contactor core. That is, the contactor body may include two contactor cores. Based on this, the discharge resistor and the contactor core may be connected by one end of the discharge resistor being connected to one end of the first contactor core and the other end of the discharge resistor being connected to one end of the second contactor core.
For example, when the discharge resistor includes a first connection terminal and a second connection terminal, the first contactor core includes a third connection terminal and a fourth connection terminal, the second contactor core includes a fifth connection terminal and a sixth connection terminal, one of the first connection terminal and the second connection terminal may be controlled to be electrically connected to one of the third connection terminal and the fourth connection terminal, and the other of the first connection terminal and the second connection terminal may be controlled to be electrically connected to one of the fifth connection terminal and the sixth connection terminal.
According to the above embodiment, the contactor body further includes a housing. Alternatively, when the discharge resistor is electrically connected to the two contactor cores, the discharge resistor may be mounted inside the housing at this time. Through this kind of mounting means, contactor body and discharge resistor all need occupy motor controller's space originally, and the present discharge resistor is installed in the inside of contactor body, reduces to only needing the space that occupies a contactor body, can improve motor controller's compact structure.
Based on the above embodiments, the present application further provides a motor controller.
The motor controller may include a power source, a main drive, and a contactor, and the power source may be used to provide power to the main circuit, i.e., to power the motor operation. The main drive can be used for controlling the on-off of the contactor, so that the on-off of the main loop is controlled. Wherein, the contactor includes: the contactor comprises a contactor body and a discharge resistor, wherein the discharge resistor is arranged on the contactor body, and the contactor body is electrically connected with the discharge resistor.
Specifically, the contactor body includes a housing and a contactor core, and the discharge resistor is electrically connected to the contactor core. The contactor in the motor controller is based on the contactor provided in the embodiment, and the space occupied by the motor controller can be reduced by installing the discharging resistor on the contactor body, so that the structural compactness of the motor controller is improved.
The following will specifically describe the motor controller in conjunction with a schematic circuit diagram. Referring to fig. 2, fig. 2 is a schematic circuit diagram of a motor controller according to an embodiment of the present application.
Optionally, in order to introduce the working principle of the motor controller, the contactor in the motor controller is split into a contactor body and a discharge resistor for introduction. The circuit includes a power source 201, a contactor core 202, a discharge resistor 203, a main drive 204, and a motor 205.
The main driver 204 can control whether current passes through the coil of the contactor core 202, so as to realize on-off control of the contactor core 202. When current passes through the coil in the contactor core 202, the coil generates electromagnetic attraction to drive the contactor core 202, so that the normally open contact of the contactor core 202 is attracted, and the contactor core 202 is closed; when no current passes through the coil, the electromagnetic attraction force disappears, the normally open contact of the contactor core 202 is reset under the action of the spring, and the contactor core 202 is restored to the open state.
When the contactor core 202 is closed, the main circuit is closed, and the power supply 201 can provide an output voltage for the main drive 204. At this time, the main drive 204 may process the output voltage of the power supply 201 according to the voltage required by the motor 205. After the motor 205 stops operating, since the main drive 204 includes components such as a capacitor, and the capacitor stores electric energy, the capacitor discharges at this time, and the discharging resistor 203 consumes the electric energy released by the capacitor in the main drive 204, so as to prevent the motor 205 from being damaged.

That is, the contactor may be divided into a first contactor core 304, a second contactor core 305, and a discharge resistor 306 connected in a circuit. One end of the discharge resistor 306 is connected to one end of the first contactor core 304, and the other end of the discharge resistor 306 is connected to one end of the second contactor core 305.
