Technical Field

[0001] The present invention belongs to the technical field of permanent magnet synchronous motor control, and in particular relates to a permanent magnet synchronous motor controller. Background Art

[0002] Permanent magnet synchronous motors (PMSMs) are widely used in new energy vehicles, aerospace, and high-end equipment due to their high power density and precise control. However, existing controllers face technical bottlenecks in structural design, cable management, and ease of maintenance.

[0003] When maintaining existing controllers, the controller needs to be completely disassembled, which results in a long maintenance cycle and is prone to damage to precision connectors. In addition, when operating in a limited operating area, the length of the cable at the rear of the controller cannot be shortened or lengthened, which is not conducive to the smooth operation of the controller. Summary of the Invention

The carrier platform is disposed at a designated position, and the pivot module is composed of an assembly plate, a hinge unit, and a clamping unit. One side of the assembly plate is hinged to the front side of the carrier platform via the hinge unit, and the other side of the assembly plate is clamped to the carrier platform via the clamping unit. The controller is locked and arranged on the assembly plate, and the rear side of the controller is in communication with the assembly plate and a storage cavity on the carrier platform.

[0006] The wire management module includes a winding roller and a power unit. The winding roller is hinged in the storage cavity of the supporting platform. A cable is wound on the winding roller. The supporting platform is connected to the controller via the cable. When the assembly piece is rotated open with the hinge unit as the center and the clamping mechanism is released, the hinge unit uses the power unit to drive the winding roller to rotate counterclockwise to lengthen the cable. When the assembly piece is closed via the hinge unit, the hinge unit uses the power unit to drive the winding roller to rotate clockwise to shorten the cable. At the same time, the clamping unit can be bolted and connected when the assembly piece is close to the supporting platform. The winding roller as a whole is in a tapered shape with the size decreasing from the clamping unit to the hinge unit.

[0008] As an optimal technical solution for a permanent magnet synchronous motor controller, the hinge unit includes a supporting base, a static ring, a dynamic ring and a pivot rod. The supporting base is arranged on one side of the outer wall of the tray, and multiple static rings are arranged on the inner side of the supporting base. The multiple static rings are rotatably sleeved on the opposite side of the pivot rod, and multiple dynamic rings are arranged on the surface of the pivot rod, and one side of the multiple dynamic rings is all fixedly connected to the assembly plate.

[0009] As an optimal technical solution for a permanent magnet synchronous motor controller, the card connection unit includes a constraint base, a joystick, an insertion rod and a positioning cavity. The constraint base is arranged on the outer wall of the tray, and a guide groove is arranged on the inner side of the constraint base. The positioning cavity is reserved on the same side of the constraint base. When the assembly piece is rotated until it is close to the tray, the axis of the positioning cavity and the guide groove coincide, and the joystick is arranged on the outer wall of the assembly piece.

[0010] As an optimal technical solution for a permanent magnet synchronous motor controller, a first elastic member is movably connected to the inner side of the guide groove, an insertion rod is movably arranged on the inner side of the guide groove, the first elastic member and the side opposite to the insertion rod are connected to each other, a curved contact portion is arranged on the side of the insertion rod away from the first elastic member, and when the assembly piece is rotated until it is close to the tray, the curved contact portion is embedded in the inner side of the positioning cavity.

[0011] As an optimal technical solution for a permanent magnet synchronous motor controller, a plurality of guide grooves are reserved on the winding roller, and a displacement track is reserved at the cavity mouth of any guide groove on the winding roller. A second elastic member and a limiting slide are movably arranged on the inner side of the displacement track. The two ends of the second elastic member are respectively connected to the wall surface of the guide channel and the inner wall surface of the limiting slide. The peripheral wall of the limiting slide is close to the wall surface of the guide channel, and an adjustment plate is arranged at the outer edge of the limiting slide.

[0012] As an optimal technical solution for a permanent magnet synchronous motor controller, the power unit includes a power roller, a first chainring, a second chainring, a first umbrella disk and a second umbrella disk.

[0013] The beneficial effects of the present invention are:

[0014] 1. The controller of the present invention is arranged on the outer wall of the assembly sheet. One end of the assembly sheet is hinged to the support platform via a hinge unit. When repairing the rear of the controller or embedding cables, the assembly sheet on the outer wall of the support platform and the controller are driven to fold apart counterclockwise, exposing the rear of the controller. The user can then stand in the operating area of ​​the controller to maintain the rear of the controller, making it convenient for the user to maintain the controller.

[0015] 2. The winding roller of the present invention is arranged at the rear of the controller on the outer wall of the supporting platform. The cable of the rear of the controller is wound on the winding roller. The cable with an adaptive margin is wound through the winding roller. When the controller is rotated and folded, the winding roller can rotate, causing the cable to be lengthened, thereby preventing the cable from being pulled out of the port by external force during the rotation of the controller, causing the controller to be unable to operate smoothly. Several groups of cables at the rear of the controller are layered and wound through the winding roller to avoid interference between the wires and improve safety.

[0016] 3. The winding roller of the present invention is hinged via a power unit and an articulated unit. When the assembly piece and the controller are arranged along with the rotation of the articulated unit, the articulated unit drives the winding roller to rotate via the power unit to achieve the effect of scaling the cable. In the process of the assembly piece and the controller being rotated and folded open via the articulated unit, the articulated unit drives the winding roller to rotate counterclockwise via the power unit to achieve the purpose of lengthening the cable, thereby avoiding the user manually rotating the winding roller counterclockwise to lengthen the cable, and facilitating the user to scale the cable. The controller and the assembly piece are bolted to the supporting platform via the clamping unit to achieve the cable bolting connection on the outer wall of the winding roller, thereby avoiding the exposed section of the cable being lengthened under the action of external traction, causing the cable with an adaptive margin to be wound around the outer wall of the winding roller, thereby avoiding the cable being pulled out of the port at the rear of the controller by external force, causing the controller to fail to operate smoothly.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figures 1-8The present invention is a permanent magnet synchronous motor controller, comprising a carrier 100, a controller 110, a pivot module 120 and a wire management module 130. The carrier 100 is placed at a designated position. The pivot module 120 is composed of an assembly piece 120a, a hinge unit and a clamping unit. One side of the assembly piece 120a is hinged to the front side of the carrier 100 via the hinge unit, and the other side of the assembly piece 120a is clamped to the carrier 100 via the clamping unit. The controller 110 is locked and assembled on the assembly piece 120a. The rear side of the controller 110 is connected to the assembly piece 120a and the storage cavity on the carrier 100. The wire management module 130 comprises a winding roller 130a and a power unit. The winding roller 130a is hinged. Connected to the storage cavity of the carrier 100, a cable 140 is wound around the winding roller 130a. The internal interface of the carrier 100 and the controller 110 is connected via the cable 140. When the assembly piece 120a is rotated open with the hinge unit as the center and the clamping mechanism is released, the hinge unit uses the power unit to drive the winding roller 130a to rotate counterclockwise to extend the cable 140. When the assembly piece 120a is closed via the hinge unit, the hinge unit relies on the power unit to drive the winding roller 130a to rotate clockwise to wind the cable 140. The clamping unit can bolt the assembly piece 120a and the carrier 100 together after the two are aligned. The winding roller 130a is in a tapered shape with its size decreasing from the clamping unit to the hinge unit.

[0031] When laying the cable 140 in the joint area at the rear of the controller 110 and the front side of the carrier 100, the first step is to use the clamping unit to release the constraint of the assembly piece 120a and the carrier 100, and then fold the assembly piece 120a counterclockwise on the front side of the carrier 100 with the hinge unit as the center, and rotate the controller 110 synchronously, so that the controller 110 gradually exposes its rear space. When the assembly piece 120a rotates, the hinge unit and the power unit control the winding roller 130a to rotate, and release the cable 140 at the rear of the controller 110, releasing the winding constraint of the original cable 140, and then winding the cable 140 to be added onto the surface of the winding roller 130a, and retaining the adaptation margin at both ends of the cable 140. , respectively connect the two ends to the ports at the rear of the carrier platform 100 and the controller 110, rotate clockwise to close the assembly piece 120a and the carrier platform 100, and then use the clamping unit to bolt the assembly piece 120a and the carrier platform 100, so that the controller 110 is arranged in the cabinet. When the assembly piece 120a is rotated and arranged, the hinge unit and the power unit drive the winding roller 130a to rotate the plurality of cables 140 at the rear of the controller 110 and wind them equidistantly around the outer wall of the winding roller 130a. When the clamping unit bolts the assembly piece 120a to the carrier platform 100, the hinge unit, the power unit and the winding roller 130a are all bolted to the assembly piece 120a, ensuring that the winding shape of the cables 140 is stable.

[0032] In this embodiment, during maintenance of the rear of the controller 110, the assembly piece 120a and the controller 110 are pushed to fold open counterclockwise with the hinge unit as the center, forming a rear operation area of ​​the controller 110 for easy maintenance by the user. A winding roller 130a is arranged at the rear of the controller 110. During the rotational arrangement of the assembly piece 120a and the controller 110 via the hinge unit, the hinge unit drives the winding roller 130a to rotate via the power unit to shorten the cable 140, so that the winding roller 130a automatically recycles the cable 140. The winding roller 130a winds up several groups of cables 140 at the rear of the controller 110 in layers to avoid interference between the cables and improve safety. During the rotational folding of the assembly piece 120a and the controller 110 via the hinge unit, the hinge unit drives the winding roller 130a to rotate via the power unit to lengthen the cables 140 to avoid interference with the opening of the controller 110, and at the same time automatically lengthens the cables 140 via the winding roller 130a.

[0033] When the controller 110 and the assembly piece 120a are bolted together via the clamping unit and the carrier 100, the hinge unit, the power unit, and the winding roller 130a are all locked with the assembly piece 120a. At this time, the cable 140 on the outer wall of the winding roller 130a is bolted together to prevent the cable 140 from being pulled out of the port due to external force.

[0034] The longitudinal cross-sectional area of ​​the winding roller 130a on the side away from the hinge unit is larger than that on the other side, and gradually increases axially from the hinge unit end to the clamping unit end, so that when the cable 140 rotates one circle, the amount of cable 140 stored or released on the outer wall has an axial gradient difference.

[0035] When the assembly piece 120a and the controller 110 are folded open counterclockwise, the cables 140 at the rear of the controller 110 adjacent to the hinge unit extend less, while the cables 140 at the rear of the controller 110 away from the hinge unit extend more. When the cables 140 are reset by rotating the different-diameter winding roller 130a, the stored lengths of several groups of cables 140 automatically match the longitudinal cross-sectional area of ​​the winding roller 130a, so that after the assembly piece 120a and the controller 110 are rotated closed, the cables 140 can be completely reset and fit on the outer wall of the winding roller 130a, thereby achieving precise control of the cables 140 in complex displacement scenarios.

[0036] Reference Figures 1-8In one embodiment, the carrier platform 100 includes a tray 100a and a support block 100b, an assembly piece 120a is arranged on the outer wall of the tray 100a, and a plurality of support blocks 100b are arranged at the rear of the tray 100a. The plurality of support blocks 100b are arranged in the cabinet via a tensioning screw; the tray 100a completely covers the front side of the support block 100b to form a neat facade effect, and when the support block 100b blocks it, a wire cavity is formed between the tray 100a and the cabinet, so that one end of the cable 140 at the rear of the controller 110 passes through the wire cavity and connects to the peripheral system. The hinge unit includes a supporting base 120b, a static ring 120c, a dynamic ring 120d and a pivot. The rotating rod 120e and the supporting base 120b are arranged on one side of the outer wall of the tray 100a, and multiple static rings 120c are arranged on the inner side of the supporting base 120b. The pivot rod 120e is rotatably connected to the side opposite to the multiple static rings 120c. At the same time, multiple dynamic rings 120d are arranged on the surface of the pivot rod 120e, and one side of the multiple dynamic rings 120d are all fixedly connected to the assembly piece 120a; when the assembly piece 120a is rotated counterclockwise to open or clockwise to close, the dynamic ring 120d rotates with the assembly piece 120a during the rotation, and then the pivot rod 120e rotates with the dynamic ring 120d through the supporting base 120b and the static ring 120c as the center.

[0037] Reference Figures 1-8 In one embodiment, the clamping unit includes a constraint base 120f, a lever 120g, an insertion rod 120i, and a positioning cavity 120l. The constraint base 120f is arranged on the outer wall of the tray 100a. A guide groove 120h is arranged on the inner side of the constraint base 120f. The positioning cavity 120l is reserved on the same side of the constraint base 120f. When the assembly piece 120a is rotated to be close to the tray 100a, the axis of the positioning cavity 120l and the guide groove 120h coincide. The lever 120g is arranged On the outer wall of the assembly piece 120a, a first elastic member 120j is movably connected to the inner side of the guide groove 120h. An insertion rod 120i is movably arranged inside the guide groove 120h. The first elastic member 120j and the insertion rod 120i are connected to each other on the side opposite to each other. A curved contact portion 120k is arranged on the side of the insertion rod 120i away from the first elastic member 120j. When the assembly piece 120a is rotated until it is close to the tray 100a, the curved contact portion 120k is embedded in the inner side of the positioning cavity 120l.

[0038] When the assembly piece 120a is closely arranged on the outer wall of the tray 100a, the insertion rod 120i is detachably connected to the assembly piece 120a through the curved contact portion 120k and the positioning cavity 120l. During the process of plugging the wires into the rear of the controller 110, a traction force is applied to the joystick 120g to drive the positioning cavity 120l to move under the control of the assembly piece 120a, so that the hole of the positioning cavity 120l can generate a circumferential constraint on the curved contact portion 120k, causing the curved contact portion 120k to withdraw toward the outside of the positioning cavity 120l. When the curved contact portion 120k withdraws from the positioning cavity 120l as a whole, the circumferential constraint ends, and continuous application of force can drive the assembly piece 120a to rotate without constraint.

[0039] Reference Figures 1-8 In one embodiment, a plurality of guide channels 130c are reserved on the winding roller 130a. A displacement track 130d is reserved at the opening of any guide channel 130c on the winding roller 130a. A second elastic member 130e and a limiting slide 130f are movably arranged on the inner side of the displacement track 130d. The two ends of the second elastic member 130e are respectively connected to the wall surface of the guide channel 130c and the inner wall surface of the limiting slide 130f. The peripheral wall of the limiting slide 130f is closely attached to the wall surface of the guide channel 130c. An adjusting piece 130g is arranged on the outer edge of the limiting slide 130f.

[0040] During the process of inserting the cable 140 on the controller 110, the plug of the cable 140 is embedded in the port at the rear of the controller 110, and then the adjusting piece 130g is pushed toward the inner side of the displacement track 130d, causing the limiting slide 130f to move toward the inner side of the displacement track 130d, so that the cavity of the guide channel 130c is exposed. At this time, the second elastic member 130e is compressed by the limiting slide 130f and a thrust in the opposite direction of compression is generated. Then, the cable 140 is inserted into the guide channel 130c, and then the thrust applied to the adjusting piece 130g is released, causing the second elastic member 130e to push the limiting slide 130f to move horizontally toward the guide channel 130c, so as to achieve the purpose of closing the cavity of the guide channel 130c again through the limiting slide 130f; The guide channel 130c constrains the cable 140 to be arranged therein, and during the rotation of the winding roller 130a, the cable 140 can be shortened and wound on the winding roller 130a; a plurality of guide channels 130c are reserved on the outer wall of the winding roller 130a, and the plurality of guide channels 130c on the outer wall of the winding roller 130a correspond to multiple groups of cables 140. The multiple groups of cables 140 are spatially separated through the guide channels 130c, so that the multiple groups of cables 140 are retracted through the winding roller 130a, and the opening and closing of the guide channel 130c is achieved under the action of the limiting slide 130f and the second elastic member 130e. The cable 140 can be arranged in the guide channel 130c without a plug of the cable 140, so that the cable 140 and the winding roller 130a can be stored without obstacle.

[0041] Reference Figures 1-8 The power unit includes a power roller 130b, a first chainring 130h, a second chainring 130i, a first umbrella disc 130j and a second umbrella disc 130k. The surfaces of the first umbrella disc 130j and the second umbrella disc 130k are arranged with tooth bars. The first chainring 130h is arranged on the outer wall of the pivot rod 120e. The second umbrella disc 130k is arranged at one end of the winding roller 130a. The power roller 130b is hinged in the groove at one end of the tray 100a. The power roller 130b and the pivot rod 120e are arranged so as not to intersect each other. The second chainring 130i and the first umbrella disc 130j are arranged on the power roller 130b. On the outer wall of 30b, the first chainring 130h and the second chainring 130i are engaged and linked, and the first umbrella disc 130j and the second umbrella disc 130k are engaged and linked; when the pivot rod 120e rotates as the assembly piece 120a opens and closes, the first chainring 130h rotates along with the pivot rod 120e, the first chainring 130h engages and drives the second chainring 130i to rotate, and controls the power roller 130b and the first umbrella disc 130j to rotate, and the first umbrella disc 130j engages and drives the second umbrella disc 130k to rotate, and controls the winding roller 130a to rotate, thereby shortening or lengthening the cable 140.

[0042] Reference Figures 1-8The controller 110 has a high-voltage auxiliary power supply that takes power from the DC bus and a low-voltage auxiliary power supply that takes power from an external low-voltage power supply, and also includes modules such as a control system, a drive circuit, and a hardware protection circuit; the power supply for the drive circuit comes from both the high-voltage auxiliary power supply and the low-voltage auxiliary power supply, the high-voltage auxiliary power supply supplies power to the drive through the power supply circuit, and the low-voltage auxiliary power supply also supplies power to the drive circuit through the power supply circuit; the power supply for the hardware protection circuit comes from both the high-voltage auxiliary power supply and the low-voltage auxiliary power supply, the high-voltage auxiliary power supply supplies power to the hardware protection circuit through the power supply circuit, and the low-voltage auxiliary power supply also supplies power to the hardware protection circuit through the power supply circuit; the power supply for the control system comes from both the high-voltage auxiliary power supply and the low-voltage auxiliary power supply, there is a power supply circuit between the high-voltage auxiliary power supply and the control system, and there is a power supply circuit between the low-voltage auxiliary power supply and the control system; the hardware protection circuit and There is a protection signal link between the drive circuits, and a protection priority circuit inside the drive circuit ensures that the protection signal is received and the protection action is performed while ignoring the PWM signal sent by the control system; to reduce costs, the low-voltage auxiliary power supply outputs a low-side drive power supply and does not output a high-side drive power supply; the low-voltage auxiliary power supply only provides the power required for active short-circuit protection when the high-voltage auxiliary power supply fails, so the power is relatively small, and the drive power output by the low-voltage auxiliary power supply is less than 30% of the high-voltage auxiliary power supply; the hardware protection circuit has a comparator circuit that compares the bus voltage with the set value. When the voltage is higher than the set value, the comparator is activated; the hardware protection circuit has a latch circuit. After the comparator is activated, the fault signal can be maintained and maintained until the power is turned off; the hardware protection circuit has a power supply voltage undervoltage detection circuit. When the power supply is undervoltage, no fault protection signal is output.

[0043] The specific implementation method is as follows: during the process of installing and removing the cable 140 at the rear of the controller 110, a traction force is first applied to the assembly piece 120a via the joystick 120g, driving the positioning cavity 120l to move under the control of the assembly piece 120a, so that the hole of the positioning cavity 120l generates a circumferential constraint on the curved contact portion 120k, causing the curved contact portion 120k to withdraw toward the outside of the positioning cavity 120l. When the curved contact portion 120k is completely withdrawn from the positioning cavity 120l, the circumferential constraint ends, and continuous application of traction can drive the assembly piece 120a to rotate without constraint. When the assembly piece 120 When the lever a is folded counterclockwise to form a right angle, the rear portion of the controller 110 is exposed to the left through the storage cavity of the assembly piece 120a. The dynamic ring 120d rotates as the assembly piece 120a rotates, causing the pivot rod 120e to rotate through the dynamic ring 120d with the supporting base 120b and the static ring 120c as the rotation center. Then, the first chainring 130h rotates along with the pivot rod 120e. The first chainring 130h engages and drives the second chainring 130i to rotate, controlling the power roller 130b and the first umbrella plate 130j to rotate. The first umbrella plate 130j engages and drives the second umbrella plate 130k to rotate. The controller 110 is moved to control the winding roller 130a to rotate, driving the winding roller 130a to execute the cable 140 lengthening action. The rear part of the controller 110 is exposed as the assembly piece 120a is folded open. The user can maintain the controller 110 or arrange the cable 140 in the operation area exposed by the tray 100a and the controller 110. Then, the adjustment piece 130g is pushed toward the inner side of the displacement track 130d, causing the limiting slide 130f to move toward the inner side of the displacement track 130d, exposing the cavity of the guide channel 130c. At this time, the second elastic member 130e is compressed by the limiting slide 130f and appears. The thrust in the opposite direction of the compression then inserts the cable 140 into the guide channel 130c. The thrust applied to the adjustment plate 130g is then released, causing the second elastic member 130e to push the limiting slide 130f to move horizontally toward the guide channel 130c. This closes the opening of the guide channel 130c again via the limiting slide 130f, causing the guide channel 130c to constrain and arrange the cable 140 therein. Subsequently, the two ends of the cable 140 are respectively embedded in the corresponding ports on the outer wall of the tray 100a and the rear of the controller 110, thereby completing the arrangement of the cable 140.Clockwise rotation of assembly piece 120a causes it to rest against the outer wall of tray 100a again. Dynamic ring 120d also rotates clockwise as assembly piece 120a rotates clockwise, causing pivot rod 120e to rotate clockwise along with dynamic ring 120d. This then causes first chainring 130h to rotate clockwise along with pivot rod 120e. The first chainring 130h engages with the second chainring 130i, causing the power roller 130b and first umbrella plate 130j to rotate counterclockwise. The first umbrella plate 130j engages with the second umbrella plate 130k, causing the winding roller 130a to rotate clockwise, thereby retrieving the cable 140 embedded in the guide channel 130c.
