DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model belong to the scope of protection of the utility model.

[0034] Referring to Figures 1 to 3 The embodiment provides a steering motor controller, which comprises a motor assembly 1, a shell 2, a control board 3, a drive board 4, a connector body 5 and at least one connector assembly 6.

[0035] The motor assembly 1 is located in the shell 2, the control board 3 is located on one side of the motor assembly 1, and the drive board 4 is located on the side, away from the motor assembly 1, of the control board 3 and is electrically connected with the motor assembly 1 and the control board 3 respectively.

[0036] The connector body 5 is arranged on the outer wall of the shell 2, and the connector assembly 6 comprises at least two connectors 61, all the connectors 61 are integrally formed on the connector body 5, one of the at least two connectors 61 is electrically connected with the control board 3, and the other of the at least two connectors 61 is electrically connected with the drive board 4.

[0037] In specific implementation, the drive board 4 is electrically connected with the motor assembly 1 to transmit alternating current. Specifically, the motor assembly 1 is provided with a motor to pin 12, the drive board 4 is provided with a motor pin connector 42, and the motor to pin 12 is plug-connected with the motor pin connector 42, so as to realize the electrical connection between the motor assembly 1 and the drive board 4. In addition, compared with welding connection, plug connection has higher operation efficiency.

[0038] It should be noted that when the motor to pin 12 is plug-connected with the motor pin connector 42, the control board 3 is arranged between the motor assembly 1 and the drive board 4, and therefore the control board 3 is provided with an avoiding through hole corresponding to the motor to pin 12, which can be passed through by the motor to pin 12 to plug-connect with the motor pin connector 42.

[0039] The control board 3 is electrically connected with the driving board 4 to transmit communication signals. Specifically, the control board 3 can be provided with a signal connector 32, and the driving board 4 is provided with a communication connector 43. The signal connector 32 is plug-connected with the communication connector 43 to realize the electrical connection between the control board 3 and the driving board 4. In addition, compared with the welding connection, the plug connection has higher operation efficiency.

[0040] The connector assembly 6 includes at least two connectors 61, and all the connectors 61 are integrally formed on the connector main body 5 to form a complete connector assembly. Compared with the mode that all the connectors 61 need to be separately assembled on the shell 2, in the embodiment, all the connectors 61 are integrated on the connector main body 5, and then the connector main body 5 is assembled on the shell 2. Therefore, all the connectors 61 do not need to be separately assembled with the shell 2, so that the assembly convenience and efficiency can be effectively improved. In addition, the integrated connector assembly can also improve the integration of the whole steering motor controller, which is conducive to realizing the design requirement of high integration.

[0041] For example, all the connectors 61 can be integrally formed on the connector main body 5 in a fisheye needle structure.

[0042] Specifically, the connector main body 5 is arranged on the outer wall of the shell 2. For example, the connector main body 5 can be connected to the outer wall of the shell 2 in a clamping or screwing manner. At this time, the whole connector main body 5 is located outside the shell 2, so that the assembly personnel can conveniently assemble the connector main body 5 on the shell 2, and the problem of occupying the internal space of the shell 2 when the connector main body 5 is assembled inside the shell 2 can be avoided.

[0043] The steering motor controller of the embodiment includes the motor assembly 1, the shell 2, the control board 3, the driving board 4, the connector main body 5, and at least one connector assembly 6. By arranging the motor assembly 1 in the shell 2, the control board 3 is located on one side of the motor assembly 1, the driving board 4 is located on the side of the control board 3 away from the motor assembly 1 and is electrically connected with the motor assembly 1 and the control board 3 respectively, one of the at least two connectors 61 of the connector assembly 6 is connected with the control board 3, and the other of the at least two connectors 61 is connected with the driving board 4, so that signal transmission and torque control can be realized to control the direction of the vehicle.

[0044] At the same time, by integrally forming all the connectors 61 on the connector main body 5, all the connectors 61 can be formed in an integrated structure. Therefore, all the connectors 61 do not need to be separately assembled with the shell 2, so that the assembly convenience and efficiency are improved, and the integrated connector assembly can also improve the integration of the whole steering motor controller.

[0045] In addition, compared with the mode that the connector body 5 is connected in the shell 2, the connector body 5 is arranged on the outer wall of the shell 2, which not only can avoid occupying the internal space of the shell 2, but also is more convenient to realize the assembly operation of the connector body 5 on the shell 2.

[0046] Referring to Figure 1 and Figure 2 In some embodiments, one of the at least two connectors 61 is a signal connector, and the other of the at least two connectors 61 is a power connector. The signal connector is electrically connected with the control board 3, and the power connector is electrically connected with the drive board 4.

[0047] Specifically, the power connector is electrically connected with the drive board 4, and is used to supply power to the drive board 4. For example, in order to save cost, the power connector can be connected with the drive board 4 by welding. The signal connector is mechanically connected with the control board 3, and is used to realize signal transmission. For example, the mechanical connection can be crimping or clamping, etc.

[0048] For example, the signal connector can integrate CAN (Controller Area Network) signals and TAS (TMR Angle Sensors) signals.

[0049] For example, when the connector assembly 6 is arranged as a group, at this time, the motor assembly 1 can be one, and the steering motor controller has one set of control system, so as to realize the design of single-redundancy steering motor controller. When the connector assembly 6 is arranged as two groups, at this time, the corresponding motor assembly 1 can be two or integrate two independent windings on the same motor assembly 1, and the steering motor controller has two independent control systems, thereby realizing the design of double-redundancy steering motor controller.

[0050] In addition, the power of the motor assembly 1 in the embodiment can be set according to actual needs, so that the steering motor controller can adapt to different voltage systems, such as 12V voltage system or 48V voltage system. When adapting to the 48V voltage system, the power of the configured motor assembly 1 is higher, so as to support higher load, so that the steering motor controller with the motor assembly 1 can match the vehicle model with higher requirements for steering response, safety, etc. For example, when adapting to the 48V voltage system, at this time, the steering angle of the whole vehicle can follow the delay of less than 50ms, and when in extreme working conditions, the response speed will be faster, which can reach the delay of less than 30ms, so as to improve the safety and experience of driving.

[0051] Referring to Figure 1 and Figure 2As shown, in some embodiments, at least two connectors 61 are arranged along the length direction of the connector body 5.

[0052] By arranging at least two connectors 61 along the length direction of the connector body 5 (refer to the x direction as shown), the space of the connector body 5 in the length direction can be effectively utilized to arrange the connectors 61, and the adjacent two connectors 61 can be effectively spaced apart to ensure that signal interference does not occur to affect the integrity of the signal. Figure 1

[0053] As shown, in some embodiments, the connector assembly 6 includes at least two groups, and the at least two groups of connector assemblies 6 are arranged along the width direction of the connector body 5. Figure 1 Figure 2 For example, when a design of a dual-redundant steering motor controller needs to be implemented, the connector assembly 6 can be arranged in two groups at this time, and the two groups of connector assemblies 6 can be arranged along the width direction of the connector body 5 (refer to the y direction as shown) to effectively utilize the space of the connector body 5 in the width direction to arrange different connector assemblies 6, and the adjacent two groups of connector assemblies 6 can be effectively spaced apart to ensure that signal interference does not occur to affect the integrity of the signal.

Figure 1 Figure 2 By integrally forming the first housing 21 and the second housing 22, the integration of the steering motor controller can be further improved, and the problem of complicated assembly caused by connecting the first housing 21 and the second housing 22 after being formed respectively can be avoided.

[0056] In addition, by integrally forming the first housing 21 and the second housing 22, the number of parts can be reduced, the cost of the mold will be relatively low, and the EMC (Electro Magnetic Compatibility, electromagnetic compatibility) performance can be improved.

[0057]

The inner cavity of the second shell 22 can be configured to match the outer contour of the control panel 3 for accommodating the control panel 3.

[0060] Specifically, by detachably connecting the connector body 5 to the second shell 22, when the connector body 5 is damaged, the connector body 5 can be detached from the second shell 22 for replacement, thereby saving costs. Exemplarily, the connector body 5 can be detachably connected to the second shell 22 by clamping or screwing.

[0061] In addition, the control panel 3 can be fixed in the second shell 22 by crimping and then screwed in the second shell 22 by the fastening connector 31, and the control panel 3 can be mechanically connected to the signal connector of the connector body 5 by crimping.

The connector body 5 is connected to the second shell 22 by a connecting piece 9 penetrating the first connecting hole and the second connecting hole 52.

[0064] That is, the second shell 22 can be fastened to the connector body 5 by the connecting piece 9 penetrating the first connecting hole and the second connecting hole 52. Exemplarily, at least one of the first connecting hole and the second connecting hole 52 can be a threaded hole, and the connecting piece 9 can be a screw or a bolt. Alternatively, the second connecting hole 52 and the second connecting hole can both be light holes, and the connecting piece 9 can be a connecting pin.

[0065] Exemplarily, the first connecting hole and the second connecting hole 52 can be provided in plurality, and the first connecting hole and the second connecting hole 52 correspond one by one, so that the connection stability of the connector body 5 and the second shell 22 can be further improved by cooperation of the plurality of first connecting holes and the plurality of second connecting holes 52.

[0066] Referring to Figure 1As shown, in some embodiments, one end of the second shell 22 protrudes from the first shell 21 along the length direction of the connector body 5, so as to form an accommodation space 24 between the first shell 21 and the second shell 22 for accommodating the connector body 5.

[0067] Specifically, the connector body 5 is arranged on the outer wall of the second shell 22, and in order to make the whole steering motor controller smaller in size and more regular in appearance, the accommodation space 24 can be formed between the second shell 22 and the first shell 21 to accommodate the connector body 5, and at this time the connector body 5 is located in the accommodation space 24 and connected with the second shell 22.

[0068] Referring to Figure 1 As shown, for example, the right end of the second shell 22 can be arranged to protrude from the first shell 21, so that the right end face of the first shell 21 and the bottom end face of the second shell 22 together enclose the accommodation space 24 to accommodate the connector body 5. Alternatively, in other implementations, the left end of the second shell 22 can also be arranged to protrude from the first shell 21, so that the left end face of the first shell 21 and the bottom end face of the second shell 22 together enclose the accommodation space 24.

[0069] Specifically, in the embodiment, the drive board 4 can be located in the second shell 22 or outside the second shell 22. Whether the drive board 4 is located in the second shell 22 or outside the second shell 22, when the connector body 5 is accommodated in the accommodation space 24, at this time the connector body 5 is located on the side of the control board 3 away from the drive board 4, so in order to facilitate the electrical connection of the connector 61 with the control board 3 or the drive board 4, at this time an avoiding hole can be arranged on the second shell 22, so that the connector 61 enters the inner cavity of the second shell 22 through the avoiding hole, and then the corresponding connector 61 is electrically connected with the control board 3 or the drive board 4.

[0070] Referring to Figures 1 to 3 As shown, in some embodiments, the steering motor controller further comprises a cover 8 located on the side of the drive board 4 away from the control board 3. The cover 8 is provided with a first mounting hole 81, the drive board 4 is provided with a second mounting hole 41, and the shell 2 is provided with a third mounting hole 25. The cover 8, the drive board 4 and the shell 2 are connected together through the fastener 7 arranged in the first mounting hole 81, the second mounting hole 41 and the third mounting hole 25.

[0071] Through the fastener 7 arranged in the first mounting hole 81, the second mounting hole 41 and the third mounting hole 25, the shell 2, the drive board 4 and the cover 8 can be directly connected together, so as to simplify the connection operation and improve the assembly efficiency.

Alternatively, the fastener 7 can be a fastening pin, and the first mounting hole 81, the second mounting hole 41 and the third mounting hole 25 can be a through hole.

[0073] Exemplarily, the first mounting hole 81, the second mounting hole 41 and the third mounting hole 25 can be provided in plurality, and the plurality of first mounting holes 81 are arranged in a circumferential direction of the upper cover 8, and the second mounting hole 41 and the third mounting hole 25 are arranged correspondingly to the first mounting hole 81, and a fastener 7 is arranged in the corresponding first mounting hole 81, the second mounting hole 41 and the third mounting hole 25 to further improve the connection stability between the upper cover 8, the driving plate 4 and the housing 2.

[0074] Referring to Figures 1 to 3 Exemplarily, the fastener 7 is integrally formed with a sealing member 71, and when the fastener 7 is arranged in the first mounting hole 81, the sealing member 71 is pressed between the first mounting hole 81 and the fastener 7.

[0075] That is, by integrally forming the sealing member 71 on the fastener 7, when the fastener 7 is arranged in the first mounting hole 81, the sealing member 71 is pressed between the first mounting hole 81 and the fastener 7 to seal the gap between the first mounting hole 81 and the fastener 7.

[0076] Exemplarily, the sealing member 71 can be a rubber sealing ring or a silica gel sealing ring. The sealing member 71 can be directly formed on the outer periphery of the fastener 7 by a thermoplastic process.

[0077] In addition, by integrally forming the sealing member 71 on the fastener 7, the fastener 7 can also have a sealing function when used for connection and fixation. Compared with the mode of separately arranging a sealing structure for sealing, the fastener 7 with the integrated sealing member 71 of the present embodiment has higher integration and occupies less space, so as to be suitable for a vehicle model with small arrangement space of a steering system.

[0078] Exemplarily, the second housing 22 can be provided with an opening 23 away from the first housing 21, so as to accommodate the motor in the first housing 21 and accommodate the control plate 3 in the second housing 22. After assembly, the upper cover 8 can be arranged at the opening 23 to close the opening 23 to prevent foreign matters from entering, and the driving plate 4 can be located outside the second housing 22 and clamped between the upper cover 8 and the housing 2.

[0079] Referring to Figure 3As shown, in some embodiments, the side of the upper cover 8 away from the motor assembly 1 is provided with a recessed groove 83, which is correspondingly arranged and communicated with the first mounting hole 81. When the fastener 7 is arranged in the first mounting hole 81, the end of the fastener 7 away from the motor assembly 1 is below the groove of the recessed groove 83, so as to avoid the problem that the fastener 7 protrudes from the groove of the recessed groove 83 and easily causes safety hazards.

[0081] That is, the receiving groove 82 is arranged on the lower side of the upper cover 8 to place the drive board 4, so as to effectively reduce the size of the entire steering motor controller in the height direction (referring to Figure 1 the z direction), which is beneficial to realize miniaturization design.

[0082] In some embodiments, the heat-conducting glue is arranged between the shell 2 and the drive board 4, and the shell 2 and the drive board 4 are in heat-conducting contact through the heat-conducting glue, so as to quickly conduct the heat generated by the devices such as the motor assembly 1 in the shell 2 to the outside through the heat-conducting glue.

[0083] For example, the heat-conducting glue is arranged in the region of the upper cover 8 corresponding to the drive board 4, so as to quickly transfer the heat inside the steering motor controller to the upper cover 8 through the heat-conducting glue and then conduct to the outside, so as to realize rapid heat dissipation.

[0084] For example, the sealing glue is arranged between the upper cover 8 and the shell 2, so as to realize the sealing cooperation between the two.

[0085] Referring to Figure 2 As shown, in some embodiments, at least one drainage groove 51 is arranged on the outer wall of the connector body 5, and the drainage groove 51 extends along the circumference of the connector body 5.

[0086] When the external rain or water falls on the connector body 5, the rain or water can be quickly conducted to the outside through the drainage groove 51, so as to waterproof the connector assembly 6 on the connector body 5.

[0087] For example, the two drainage grooves 51 can be arranged at intervals along the length direction of the steering motor controller (referring to Figure 1 the x direction), so that when the amount of external rain or water is large, the rain or water can be discharged from different drainage grooves 51, so as to ensure the waterproof effect.
