Description

Technical Field

[0001] The present invention relates to the technical field of vehicle drive controllers, and in particular to a multi-channel motor drive controller for unmanned vehicles. Background Art

[0002] The multi-motor drive controller for autonomous vehicles is a component of the autonomous driving powertrain. Its design must balance efficient drive, heat dissipation management, and safety redundancy. It supports independent control of three-wheel drive or four-wheel drive motors. With the rapid development of autonomous driving technology, vehicle drive systems must meet high precision, high reliability, and dynamic response requirements. Traditional internal combustion engines or single-motor drives struggle to adapt to complex scenarios such as emergency obstacle avoidance and path optimization. Multi-motor drive controllers, by independently controlling multiple in-wheel motors or distributed motors, achieve torque vectoring, redundant fault tolerance, and energy efficiency optimization, becoming a core executive component of intelligent driving.

[0003] When the current multi-channel motor drive controller of an unmanned vehicle is in use, the vehicle will experience vibrations of various frequencies during driving, especially when driving on rugged roads or at high speeds. The existing seismic structure may perform well under low-frequency vibrations, but for high-frequency vibrations, the electronic components inside the controller may still suffer fatigue damage. If the circuit board inside the controller is subjected to high-frequency vibrations for a long time, it may cause the solder joints to loosen and the connecting wires to break, thereby affecting the normal operation of the controller. At the same time, there is a lack of utilization and processing of harmful high-frequency vibrations.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the suspension mechanism and the power supply mechanism, can subject the permanent magnet block and the control circuit board to an upward suspension force, so that a non-rigid connection is formed between the control circuit board and the main controller. Therefore, when the main controller is subjected to high-frequency vibration caused by the operation of the vehicle, the vibration cannot be transmitted through the rigid connection, thereby effectively reducing the deformation of the control circuit board caused by long-term high-frequency vibration, thereby reducing the risk of loose solder joints and broken connecting wires due to stress in electronic components, and helping to maintain stable current and signal transmission of the control circuit board for a long time. At the same time, the lever formed by the connecting rod is used to amplify the vibration, and the piezoelectric ceramic sheet is used to convert the vibration energy into electrical energy, thereby realizing energy recovery and reuse. No additional external power supply is required to power the electromagnetic coil, and harmful high-frequency vibration is fully utilized, reducing energy consumption. In addition, after the control circuit board is suspended, a certain gap is formed between it and the machine casing, which is conducive to air circulation and enhances the heat dissipation effect. 2. The present invention can reduce the impact of external electromagnetic interference on signal transmission on the control circuit board through the sealing mechanism and the limiting mechanism, and also prevent the high-frequency signal on the control circuit board from radiating outward and affecting the electromagnetic coil, thereby ensuring the stability of their mutual operation. At the same time, the upper wrapping sleeve and the lower support sleeve can provide good limiting support for the control circuit board, ensuring that the control circuit board will not be randomly displaced under vibration and impact during vehicle driving, and there will be no direct rigid contact when suspended, thereby ensuring the accuracy and stability of signal transmission on the control circuit board; 3. The present invention uses a conduction mechanism to miniaturize the fan blade seat and integrate it on the control circuit board. It can be set next to the components with large heat generation on the control circuit board to carry out targeted heat dissipation treatment for high-power components, avoiding the problem of uneven cooling caused by concentrated heat dissipation and thus reducing the working efficiency of the control circuit board. At the same time, the fan blade seat can convert the vibration energy of the piezoelectric ceramic piece into electrical energy for utilization, thereby reducing the use of additional external power supply, further reducing dependence on traditional power supply, and reducing energy consumption.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem that the electronic components inside the controller will be fatigue damaged due to high-frequency vibration, the circuit board inside the controller will be subjected to high-frequency vibration for a long time, which may cause the solder joints to loosen and the connecting wires to break, thereby affecting the normal operation of the controller, and there is a lack of technical problems in the utilization and treatment of harmful high-frequency vibration, such as Figures 1-6 As shown, the following preferred technical solutions are provided: a multi-channel motor drive controller for an unmanned vehicle, comprising a main controller 1 and a power supply mechanism 3 provided at an input end on the front side of a suspension mechanism 2. The suspension mechanism 2 is provided at the middle portion of the inner side of the main controller 1. The main controller 1 comprises a housing 101 provided outside the main controller 1. A fixing ear 102 is fixed to the bottom of the housing 101, and a wiring port 103 is provided on the front side surface of the housing 101. A heat dissipation fin 104 is provided on the upper surface of the housing 101. The lower surface of the lower bonding sheet 307 is bonded to the inner wall surface of the housing 101. The suspension mechanism 2 includes a control circuit board 201 disposed within the main controller 1. An energy storage battery 202 is disposed on one side of the upper surface of the control circuit board 201, and a voltage regulator 203 is disposed on the front side of the energy storage battery 202. A first connecting line 204 is connected below the energy storage battery 202, and an electromagnetic coil 205 is disposed at the output end of the first connecting line 204. A permanent magnet block 206 is disposed on the upper side of the electromagnetic coil 205. The energy storage battery 202 is electrically connected to the voltage regulator 203 via the control circuit board 201, and the energy storage battery 202 is electrically connected to the electromagnetic coil 205 via the first connecting line 204. The control circuit board 201 is magnetically connected to the electromagnetic coil 205 via the permanent magnet 206. The control circuit board 201 is provided with a rectifier circuit, and the voltage regulator 203 is a voltage stabilization circuit. The existing electromagnetic coil 205, in conjunction with the control circuit board 201 provided with a conventional Hall effect sensor and a microcontroller, can generate a mutually repelling magnetic force with the permanent magnet 206 when powered on. The power supply mechanism 3 includes a fixed shell 301 fixed to the surface of the machine housing 101. A piezoelectric ceramic piece 302 is fixedly mounted on one side of the upper portion of the fixed shell 301, and a second connecting line 303 is connected to one side of the piezoelectric ceramic piece 302. A rotating base 304 is fixedly provided at the lower portion of the fixed shell 301, and a connecting rod 305 is rotatably connected to the middle portion of the rotating base 304. An upper bonding piece 306 is provided above one side of the connecting rod 305, and a lower bonding piece 307 is provided below the other side of the connecting rod 305. A support spring 308 is connected to the lower portion of the middle portion of the connecting rod 305. The connecting rod 305 is rotatably connected to the fixed shell 301 through the rotating seat 304, and the connecting rod 305 is elastically connected to the fixed shell 301 through the supporting spring 308. The upper surface of the upper bonding piece 306 is bonded to the lower surface of the piezoelectric ceramic piece 302. The piezoelectric ceramic piece 302 is electrically connected to the energy storage battery 202 through the second connecting line 303. The rotating seat 304 is arranged on the right side of the connecting rod 305, so that the upper bonding piece 306 and the lower bonding piece 307 form a lever using the connecting rod 305 and the rotating seat 304. At the same time, the fixed shell 301 and the piezoelectric ceramic piece 302 can be provided in multiple groups in the main controller 1, and distributed at the corners or edges of the shell 101, near the heat dissipation fins 104, and at vibration nodes on the circuit board, where vibration is relatively strong, to ensure that vibration can be effectively sensed; Through the lower bonding piece 307, when it is bonded to the machine housing 101 and subjected to high-frequency vibration, the vibration can be transmitted to the upper bonding piece 306 by utilizing the connection rod 305, the rotating seat 304 and the supporting spring column 308 to make a corresponding vibration response. The upper bonding piece 306 can further transmit the vibration to the piezoelectric ceramic piece 302 bonded thereto. The piezoelectric ceramic piece 302 according to the existing principle can utilize the piezoelectric effect to convert the vibration force, that is, mechanical energy, into electrical energy. Through the conduction of electrical energy by the second connecting line 303, in conjunction with the rectifier circuit provided on the control circuit board 201, the electrical energy can be stored in the energy storage battery 202. Through the action of the voltage stabilizing circuit of the voltage stabilizer head 203, the electrical energy can be applied to the electromagnetic coil 205 to energize it. The magnetic field generated by the current interacts with the permanent magnet block 206, which can cause the permanent magnet block 206 and the control circuit board 201 to be subjected to an upward suspension force, so that a voltage is formed between the control circuit board 201 and the main controller 1. In the state of non-rigid connection, when the main controller 1 is subjected to high-frequency vibration caused by the operation of the vehicle, because there is no direct mechanical rigid connection between the main controller 1 and the control circuit board 201, the vibration cannot be transmitted through the rigid connection, thereby effectively reducing the deformation of the control circuit board 201 caused by long-term high-frequency vibration, thereby reducing the risk of loose solder joints and broken connecting wires due to stress of electronic components, and helping to maintain stable current transmission and signal transmission of the control circuit board 201 for a long time. At the same time, the lever formed by the connecting rod 305 is used to amplify the vibration, and the piezoelectric ceramic piece 302 is used to convert vibration energy into electrical energy, thereby realizing energy recovery and reuse. No additional external power supply is required to power the electromagnetic coil 205, and harmful high-frequency vibrations are fully utilized, reducing energy consumption. After the control circuit board 201 is suspended, a certain gap is formed between it and the machine casing 101, which is conducive to air circulation and enhanced heat dissipation. The model of the piezoelectric ceramic piece 302 can be PZT-5H.

[0021] In order to solve the technical problems of poor stability of the suspension setting of the circuit board in the controller and susceptibility to electromagnetic interference, such as Figure 3 、 Figure 4 as well as Figure 7 and Figure 8 As shown, the following preferred technical solution is provided: a sealing mechanism 4 is provided on the outside of the suspension mechanism 2, and the sealing mechanism 4 includes an upper wrapping sleeve 401 provided on the outside of the permanent magnet block 206, and a bonding layer 402 is provided on the middle part of the upper surface of the upper wrapping sleeve 401, and the upper wrapping sleeve 401 is bonded to the control circuit board 201 through the bonding layer 402; A lower support sleeve 403 is provided below the upper wrapping sleeve 401, and the electromagnetic coil 205 is provided in the lower support sleeve 403. A folding ring 404 is provided in the middle of the outer surface of the lower support sleeve 403. The outer surfaces of the upper wrapping sleeve 401, the lower support sleeve 403 and the folding ring 404 are all provided with a shielding coating 405. The permanent magnet block 206 and the electromagnetic coil 205 can be electromagnetically sealed through the sealing mechanism 4. A limiting mechanism 5 is provided on both sides of the interior of the sealing mechanism 4. The limiting mechanism 5 includes a movable cavity 501. Fixed guide rods 502 are provided above both sides of the movable cavity 501. The fixed guide rods 502 are fixedly connected to the upper wrapping sleeve 401, and a fixed protrusion 503 is fixed to the bottom of the fixed guide rod 502. A limiting groove 504 is provided on the outer side of the fixed guide rod 502. The upper wrapping sleeve 401 is slidably connected to the lower support sleeve 403 through the fixed guide rod 502, the fixed protrusion 503 and the limiting groove 504. The limiting groove 504 is wide at the bottom and narrow at the bottom. At the same time, the inner diameter of the limiting groove 504 is slightly larger than the outer diameter of the fixed guide rod 502 and the fixed protrusion 503; The folding ring 404 is fixedly connected to the lower end surface of the upper wrapping sleeve 401 and the outer surface of the lower support sleeve 403 at the upper and lower parts respectively, so that the joint between the upper wrapping sleeve 401 and the lower support sleeve 403 can be sealed. At the same time, when the permanent magnet block 206 is suspended upward and the upper wrapping sleeve 401 moves upward, the folding ring 404 can make corresponding expansion deformation according to the upward movement, so as to adapt to the displacement of the upper wrapping sleeve 401 and always ensure the sealing of the joint. The shielding coating 405, which can be a graphene coating, can make the sealed upper wrapping sleeve 401 and the lower support sleeve 403 play a certain electromagnetic shielding role on the internal permanent magnet block 206 and the electromagnetic coil 205, reducing The influence of external electromagnetic interference on the signal transmission on the control circuit board 201 is also prevented, and the high-frequency signal on the control circuit board 201 is prevented from radiating outward and affecting the electromagnetic coil 205. By fixing the guide rod 502 and the fixed protrusion 503 in the upper and lower limit movement in the limit groove 504, when the control circuit board 201 is not suspended, the upper wrapping sleeve 401 and the lower support sleeve 403 can provide good limit support for the control circuit board 201, ensuring that the control circuit board 201 will not be randomly displaced due to vibration and impact during vehicle driving, and there will be no direct rigid contact when suspended, thereby ensuring the accuracy and stability of the signal transmission of the control circuit board 201.

[0022] In order to solve the technical problems of not being able to reduce temperature in a targeted manner and relying too much on traditional power supply for cooling, such as Figure 3 、 Figure 4 as well as Figure 9 and Figure 10As shown, the following preferred technical solution is provided: a conduction mechanism 6 for heat dissipation is provided in the middle of the surface of the suspension mechanism 2, and the conduction mechanism 6 includes a fixing seat 601 fixed to the surface of the control circuit board 201, a support pad 602 is provided in the upper middle of the fixing seat 601, and a fan seat 603 is fixed in the upper middle of the support pad 602, a power motor 604 is installed in the rear middle of the fan seat 603, and an air outlet 605 is provided in the middle of the front surface of the fan seat 603, electrical contacts 606 are provided on both sides of the bottom surface of the fixing seat 601, and a plug guide rod 607 is provided in the lower middle of the fixing seat 601, and a plug seat 608 is provided directly below the plug guide rod 607; The power motor 604 is electrically connected to the control circuit board 201 through the fixing seat 601 and the electrical contact 606, and the power motor 604 is electrically connected to the main controller 1 through the plug-in guide rod 607 and the plug-in seat 608. The support pad 602 is made of rubber. The electrical contact 606 is electrically connected to the energy storage battery 202 on the control circuit board 201. The fan blade seat 603 is provided with a fan blade that is rotatably connected to the power motor 604. The electric energy converted from vibration can be utilized through the conduction mechanism 6 to directly dissipate heat from the control circuit board 201. By plugging the guide rod 607, when the vehicle is running slowly and the control circuit board 201 is not subjected to high-frequency vibration and is not suspended, the plugging guide rod 607 is plugged and electrically connected with the socket 608. At this time, the power motor 604 is powered by the circuit of the main controller 1 through the socket 608 to drive the fan blades in the fan blade seat 603 to rotate, thereby dissipating the heat of the components. When the control circuit board 201 is subjected to high-frequency vibration and is suspended, the plugging guide rod 607 is separated from the socket 608, and the power motor 604 is powered by the energy storage battery 202 connected to the electrical contact 606. The fan blades are driven to rotate and dissipate heat. At the same time, the fan blade seat 603 is miniaturized and integrated on the control circuit board 201, and can be set next to the components with large heat generation on the control circuit board 201 to carry out targeted heat dissipation treatment for high-power components, avoiding the problem of concentrated heat dissipation causing uneven cooling and reducing the working efficiency of the control circuit board 201. At the same time, the fan blade seat 603 can convert the vibration energy of the piezoelectric ceramic piece 302 into electrical energy for utilization, thereby reducing the use of additional external power supply, further reducing dependence on traditional power supply, and reducing energy consumption.
