Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor controllers, in particular to a new intelligent motor controller. Background Art
[0002] The motor controller is a device that controls the energy transmission between the power supply and the drive motor, and is composed of a control signal interface circuit, a drive motor control circuit, and a drive circuit. That is, it converts the DC power of the power battery into AC power, and controls the target torque and speed sent by the vehicle controller for output. The hardware of the motor controller is usually divided into a control board and a drive board.
[0003] The control board mainly includes the main control chip, CAN network, sampling circuit, resolver circuit and power supply circuit, etc. The existing intelligent motor controller is widely used in electric drive equipment such as electric vehicles. Since there is less space available for installation on electric vehicles, the motor controller has less space when installed. After installation, even if the conventional disassembly procedure is followed, it may be difficult to disassemble due to the deformation of the shell or insufficient reserved space, making it difficult to carry out the maintenance work normally;
[0004] Moreover, during the disassembly process, the motor controller needs to be taken out. During this process, due to the small space, the shell of the motor controller needs to be squeezed hard, which may cause damage to the shell of the motor controller, thereby destroying the internal sealing of the motor controller, making the motor controller easy to be damaged during long-term use of the equipment.
[0005] The shell of the existing motor controller is relatively thin, and the equipment may vibrate or collide during operation. At this time, the motor controller is easily damaged due to poor anti-slip properties, making the motor controller poorly adaptable to complex environments. In addition, the existing motor controller does not have enough space during installation, so the heat dissipation effect is not very good. Heat is easily accumulated at the motor controller, causing circuit board failure. For this reason, we propose a new intelligent motor controller to solve the above problems. Utility Model Content

[0024] See also Figure 1-4The utility model provides an embodiment: an intelligent new motor controller, comprising a mounting box 1, a box cover 2 is mounted on the mounting box 1,
[0025] A motor controller body 3 is installed in the installation box 1, and the motor controller body 3 is fixedly installed on the installation box 1. A line connection hole 4 is provided on the motor controller body 3. A line placement hole 5 is provided on the front side of the box cover 2 and the installation box 1. The position of the line placement hole 5 is opposite to the position of the line connection hole 4. A support rod 6 is fixedly installed in the installation box 1, and the support rod 6 is against the motor controller body 3. The support rods 6 are connected by connecting iron sheets 7.
[0026] A heat dissipation mechanism, which is arranged between the support rods 6 and is used to increase the heat dissipation efficiency of the device;
[0027] The taking mechanism is arranged on the motor controller body 3, and the taking mechanism makes it easy to take out the motor controller body 3. The heat dissipation performance of the device is increased by the heat dissipation mechanism. In addition, the taking mechanism is also arranged to make the disassembly of the motor controller body 3 easier, further increasing the convenience of the device when in use;
[0028] Furthermore, a rubber pad 8 is fixedly installed at the end of the support rod 6, and a trapezoidal block 9 is fixedly installed on the inner wall of the motor controller body 3. The rubber pad 8 fits tightly with the trapezoidal block 9. This structure enables the support rod 6 to exert a smaller unit pressure on the outside of the motor controller body 3 when supporting the motor controller body 3, thereby increasing the stability of the equipment when in use.
[0029] Furthermore, the heat dissipation mechanism includes heat dissipation holes 10, and the heat dissipation holes 10 are arranged in an array on the connecting iron sheet 7. The connecting iron sheet 7 is inserted into the support rod 6. The connecting iron sheet 7 is arranged in an array on the connecting iron sheet 7. The iron column 11 passes through the installation box 1. This structure makes the heat transfer efficiency in the installation box 1 higher, and also makes the support rod 6 more solid.
[0030] Furthermore, screws 12 are inserted at the four corners of the box cover 2, and four groups of fixing blocks 13 are installed between the connecting iron sheet 7 and the mounting box 1. A screw sleeve 14 is arranged in the fixing block 13, and the screw sleeve 14 is connected to the screw 12 through a threaded sleeve. This structure enables the motor controller body 3 to be stably installed in the mounting box 1.
[0031] Furthermore, a grid bar 16 is fixedly installed on the lower side of the box cover 2 and the installation box 1. The lower side of the box cover 2 and the bottom surface of the installation box 1 are not in direct contact with the motor controller body 3. The grid bar 16 fits the upper and lower sides of the motor controller body 3. A rubber ring 15 is arranged in the line placement hole 5. This structure makes the heat dissipation of the equipment better, and also allows the line to be stably placed in the line placement hole 5.
[0032] Furthermore, the taking mechanism includes a rubber block 17, which is fixedly mounted on the left and right sides of the motor controller body 3. The width of the upper end of the rubber block 17 is greater than the width of the lower side. There is an obvious gap between the upper end of the rubber block 17 and the connecting iron sheet 7. This structure makes it easy to take out and install the motor controller body 3, further increasing the convenience of using the device.
[0033] Working principle: When in use, the installation box 1 is fixed in the equipment where the motor controller body 3 is required by welding or bolting, and then the motor controller body 3 is placed in the installation box 1 so that the support rod 6 is against the trapezoidal block 9. Then after the lines are connected, the box cover 2 is closed on the installation box 1, and the box cover 2 is fixed by screwing the screw 12 into the screw sleeve 14. The heat generated by the motor controller body 3 during operation will be adsorbed and dispersed by the iron sheet 7. The same is true for disassembly. When taking out the motor controller body 3, you can hold the rubber block 17 with your fingers to lift out the motor controller body 3. The above is the entire working principle of the utility model.
