Description

Technical Field

[0001] This invention relates to the field of motor technology, and more specifically, to a terminal structure, a bus assembly, a motor structure, an electric power steering system, and a vehicle. Background Technology

[0002] Currently, when installing terminals on the busbars in existing motors, the terminals have a relatively simple structure, usually L-shaped plates. After being installed on the busbars and used inside the motor housing, they occupy additional space in the radial direction, increasing the overall size of the motor, resulting in low space utilization, and failing to meet the design requirements for miniaturization. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, an embodiment of the first aspect of the present invention provides a terminal structure.

[0005] A second aspect of the present invention provides a bus assembly.

[0006] An embodiment of the third aspect of the present invention provides a motor structure.

[0007] A fourth aspect of the present invention provides an electric power steering system. An embodiment of the fifth aspect of the present invention provides a vehicle.

[0008] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a terminal structure, including: a first connecting plate and a second connecting plate connected together, with the first connecting plate and the second connecting plate forming an included angle of a first angle; wherein, a notch is provided on the second connecting plate at a position where it is connected to the first connecting plate, and on the end face of the second connecting plate, at least a portion of the projection of the first connecting plate is located within the projection of the second connecting plate.

[0009] The terminal structure provided by an embodiment of the present invention includes a first connecting plate and a second connecting plate formed at a certain angle. A notch is provided at the position where the two connecting plates are connected. Specifically, the notch is provided on the second connecting plate, and the first connecting plate extends outward from the notch. It can be understood that since the first connecting plate extends from the notch, a portion of the structure overlaps with the second connecting plate. That is, the projection of part of the first connecting plate on the end face of the second connecting plate is confined within the second connecting plate, thereby greatly reducing the overall width of the terminal structure, making it easier to improve space utilization, and allowing for better combination forms for specific layout schemes.

[0010] Furthermore, when the terminal structure is installed on the busbar, the width direction of the second connecting plate coincides with the radial direction of the busbar, thereby reducing the occupation of the radial space of the busbar, thus reducing the unnecessary increase in the radial dimension of the motor, which is more conducive to the design concept of motor miniaturization.

[0011] It can be understood that the end face of the second connecting plate is the end face of both ends in the length direction of the second connecting plate. When the second connecting plate is a straight plate, the end face of the second connecting plate is the thickness surface.

[0012] The first angle can be an acute angle, a right angle, or an obtuse angle.

[0013] The above technical solution also includes: a protrusion structure, which is disposed at the end of the second connecting plate away from the first connecting plate, and the protrusion structure protrudes along the thickness direction of the second connecting plate.

[0014] In this technical solution, by providing a protruding structure at the protruding end of the second connecting plate, that is, the end furthest from the first connecting plate, the connection strength between the terminal structure and the connected structure can be effectively increased. It can be understood that the protruding structure increases the contact area, which on the one hand increases the welding area during welding, ensuring sufficient welding, and also has a certain effect of reducing welding resistance. On the other hand, under the action of the protruding structure, when it extends into the connected structure, the protruding structure can play a certain locking role, thereby achieving initial positioning.

[0015] In the above technical solution, the end of the first connecting plate away from the second connecting plate is bent in a direction away from the second connecting plate.

[0016] In this technical solution, by restricting the shape of the first connecting plate to limit the existence of bending sections, the first connecting plate can be used for connection after bending, and the terminal structure as a whole can be normally connected to the structure to be connected, such as the stator structure.

[0017] Specifically, the bending direction of the first connecting plate is outward, that is, away from the second connecting plate, so as to achieve connection with the external structure without affecting the normal structure of the second connecting plate.

[0018] In the above technical solution, the second connecting plate specifically includes a connected straight segment and a misaligned segment, with a notch located in the misaligned segment, and the first connecting plate is connected to the misaligned segment through the notch.

[0019] In this technical solution, the second connecting plate mainly includes two plate segments. One is a straight segment with a protruding structure to facilitate connection with other structures. The straight connection structure is more conducive to the fit. The other is a misaligned segment with a notch at the edge. The first connecting plate is directly connected to the notch of the misaligned segment.

[0020] In the above technical solution, the first connecting plate is a straight plate.

[0021] In this technical solution, the first connecting plate can be a straight plate, and the structure of a straight plate is easier to process.

[0022] The first connecting plate can be a rectangular plate, a circular plate, or even a plate of any shape.

[0023] An embodiment of the second aspect of the present invention provides a bus assembly, comprising: a bus body having a plurality of hook portions for leading out winding wires; a fixing member disposed at one end of the bus body; and at least one terminal structure as described in the first aspect above, disposed on the fixing member, wherein a first connecting plate of the terminal structure is in contact with the fixing member.

[0024] The bus assembly proposed according to the present invention includes a bus body, a fixing member, and a terminal structure. Specifically, the bus body is provided with a plurality of hook portions, which are mainly used to cooperate with the stator winding so that the winding wires of the winding are led outward through the hook portions. In addition, a fixing member is provided at one end of the bus body. Under the action of the fixing member, the terminal structure provided on the fixing member is electrically connected to the structure in contact with the fixing member, specifically the stator, thereby realizing normal electrical connection.

[0025] The number of terminal structures provided on the fastener can be one or more, generally three or six.

[0026] Furthermore, the first connecting plate of the terminal structure is arranged radially.

[0027] Furthermore, since the bus assembly includes any of the above-described terminal structures, it has the beneficial effects of any of the terminal structures in the first aspect, which will not be elaborated further here.

[0028] Furthermore, the busbar itself is ring-shaped, and by setting multiple spaced terminal structures, the circumferential structure of the busbar can be utilized to make more rational use of the limited space and improve space utilization.

[0029] In the above technical solution, the hook part specifically includes: a first hook, which is located on the radial inner side of the busbar body; and a second hook, which is located on the radial outer side of the busbar body.

[0030] In this technical solution, the hook portion includes a first hook and a second hook respectively disposed radially inside and radially outside the busbar. The first hook allows the winding wire to be drawn out radially from the inside of the busbar, and similarly, the second hook allows the winding wire to be drawn out radially from the outside of the busbar. Multiple first and second hooks can be provided on the busbar body, and the specific configuration can be flexibly adjusted according to the actual application scenario.

[0031] The above technical solution also includes: a controller substrate, on which mounting holes are formed, a second connecting plate of the terminal structure passes through the mounting holes, and the protrusion structure of the terminal structure is located inside the mounting holes; wherein, the controller substrate is welded to the second connecting plate.

[0032] In this technical solution, a controller substrate is provided with mounting holes to facilitate the insertion of terminal structures. When inserted, the protrusion structure is located within the mounting holes, which facilitates subsequent soldering operations.

[0033] The above technical solution also includes: a support member disposed on the fixing member, the support member being hollow inside, the second connecting plate of the terminal structure extending outward through the support member, and the protrusion structure of the terminal structure extending outward from the support member.

[0034] In this technical solution, by setting a support on the fixing member, the second connecting plate of the terminal structure will extend outward through the hollow support member. The extended part retains a protruding structure to facilitate welding with the controller substrate and realize normal electrical control.

[0035] An embodiment of the third aspect of the present invention provides a motor structure, including: a rotor structure; a stator structure, coaxially arranged with the rotor structure, wherein any bus assembly of the second aspect is disposed at one end of the stator structure and the bus assembly is electrically connected to the stator structure.

[0036] The motor structure proposed according to the present invention includes a rotor structure and a stator structure arranged coaxially. The rotor structure is disposed inside the stator structure, forming an inner rotor and outer stator motor structure. Under the action of the outer stator structure, a changing magnetic field is generated, thereby driving the rotor structure to rotate. Furthermore, a busbar assembly is disposed at one end of the stator structure and is electrically connected to the stator structure, thereby realizing the control of the stator structure.

[0037] Furthermore, since the motor structure includes any of the aforementioned stator components, it possesses the beneficial effects of any of the stator components in the second aspect, which will not be elaborated further here.

[0038] An embodiment of the fourth aspect of the present invention provides an electric power steering system, including the motor structure of the third aspect embodiment described above. Therefore, the electric power steering system provided by the present invention has all the beneficial effects of the motor provided in any of the above technical solutions.

[0039] Among them, the electric power steering system is an electric power steering system that directly relies on an electric motor to provide auxiliary torque power. Compared with the traditional hydraulic power steering system (i.e., HPS system), the EPS system (i.e., electric power steering system) has many advantages.

[0040] Furthermore, EPS mainly consists of torque sensors, vehicle speed sensors, motors, reduction gears, and electronic control units.

[0041] An embodiment of the fifth aspect of the present invention provides a vehicle, comprising: a vehicle body; any of the motor structures described in the third aspect above, disposed within a housing, or including the electric power steering system described in the fourth aspect above.

[0042] The vehicle proposed according to the present invention includes a vehicle body and a motor structure disposed within the vehicle body. The housing mainly provides certain protection for the motor structure. Since the motor structure is disposed within the vehicle body, it has the beneficial effects of any motor structure in the third aspect embodiment described above, which will not be elaborated further here.

[0043] In vehicles, the motor structure can serve as the main drive structure, i.e., an electric vehicle, or as the drive structure for other equipment inside the vehicle, such as a fan or an electric power steering system.

[0044] Additional aspects and advantages of the invention will become apparent in the following description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0047] To better understand the above-described objectives, features, and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0049] The following reference Figures 1 to 10 Some embodiments of the present invention are described. Example

[0050] like Figure 1 and Figure 2As shown, the terminal structure 100 proposed in this embodiment includes a first connecting plate 102 and a second connecting plate 104 formed at a certain angle. A notch 1042 is provided at the position where the two connecting plates are connected. Specifically, the notch 1042 is provided on the second connecting plate 104, and the first connecting plate 102 extends outward from the notch 1042. It can be understood that since the first connecting plate 102 extends from the notch 1042, a part of the structure overlaps with the second connecting plate 104. That is, the projection of part of the first connecting plate 102 on the end face of the second connecting plate 104 is restricted within the second connecting plate 104, thereby greatly reducing the overall width of the terminal structure 100, making it easier to improve space utilization, and allowing for better combination forms for specific layout schemes.

[0051] Furthermore, when the terminal structure 100 is installed on the busbar, the width direction of the second connecting plate 104 coincides with the radial direction of the busbar, thereby reducing the occupation of the radial space of the busbar, thus reducing the unnecessary increase in the radial dimension of the motor, which is more conducive to the design concept of motor miniaturization.

[0052] It can be understood that the end face of the second connecting plate 104 is the end face of both ends in the length direction of the second connecting plate 104. When the second connecting plate 104 is a straight plate, the end face of the second connecting plate 104 is the thickness surface.

[0053] The first angle can be an acute angle, a right angle, or an obtuse angle. Example

[0054] like Figure 1 As shown, the terminal structure 100 proposed in this embodiment includes a first connecting plate 102 and a second connecting plate 104 formed at a certain angle. A notch 1042 is provided at the position where the two connecting plates are connected. Specifically, the notch 1042 is provided on the second connecting plate 104, and the first connecting plate 102 extends outward from the notch 1042. It can be understood that since the first connecting plate 102 extends from the notch 1042, a part of the structure overlaps with the second connecting plate 104. That is, the projection of part of the first connecting plate 102 on the end face of the second connecting plate 104 is restricted within the second connecting plate 104, thereby greatly reducing the overall width of the terminal structure 100, making it easier to improve space utilization, and allowing for better combination forms for specific layout schemes.

[0055] A protruding structure 1044 is provided at the protruding end of the second connecting plate 104, that is, the end away from the first connecting plate 102, which can effectively increase the connection strength between the terminal structure 100 and the connected structure. It can be understood that the protruding structure 1044 increases the contact area. On the one hand, it increases the welding area during welding, ensuring sufficient welding, and also has a certain effect of reducing welding resistance. On the other hand, under the action of the protruding structure 1044, when it extends into the connected structure, the protruding structure 1044 can play a certain locking effect, thereby achieving initial positioning.

[0056] In one specific embodiment, the second connecting plate 104 mainly includes two plate segments. One is a straight segment 1046, on which a protrusion structure 1044 is provided to facilitate connection with other structures. The straight connection structure is more conducive to cooperation. The other is a misaligned segment 1048, on which a notch 1042 is provided at the edge. The first connecting plate 102 is directly connected to the notch 1042 of the misaligned segment 1048.

[0057] Furthermore, when the terminal structure 100 is installed on the busbar, the width direction of the second connecting plate 104 coincides with the radial direction of the busbar, thereby reducing the occupation of the radial space of the busbar, thus reducing the unnecessary increase in the radial dimension of the motor, which is more conducive to the design concept of motor miniaturization.

[0058] It can be understood that the end face of the second connecting plate 104 is the end face of both ends in the length direction of the second connecting plate 104. When the second connecting plate 104 is a straight plate, the end face of the second connecting plate 104 is the thickness surface.

[0059] The first angle can be an acute angle, a right angle, or an obtuse angle.

[0060] For the first connecting plate 102, in a specific embodiment, such as Figure 2 As shown, its shape can be a straight plate.

[0061] In another specific embodiment, such as Figure 1 As shown, its shape is a bent plate. After bending, the first connecting plate 102 can be used for connection. The terminal structure 100 as a whole can be normally connected to the structure to be connected, such as the stator structure.

[0062] Specifically, the bending direction of the first connecting plate 102 is outward, that is, away from the second connecting plate 104, so as to achieve connection with the external structure without affecting the normal structure of the second connecting plate 104. Example

[0063] like Figure 4 , Figure 5 and Figure 6 As shown, the bus assembly 110 proposed in this embodiment includes a bus body 112, a fixing member 116, and a terminal structure. Specifically, the bus body 112 is provided with a plurality of hook portions 114. The hook portions 114 are mainly used to cooperate with the stator winding so that the winding wires of the winding are led outward through the hook portions 114. In addition, a fixing member 116 is provided at one end of the bus body 112. Under the action of the fixing member 116, the terminal structure provided on the fixing member 116 is electrically connected to the structure in contact with the fixing member 116, specifically the stator, thereby realizing normal electrical connection.

[0064] The number of terminal structures provided on the fastener 116 can be one or more, generally three or six.

[0065] Furthermore, the first connecting plate 102 of the terminal structure is arranged radially.

[0066] Furthermore, since the bus assembly 110 includes any of the above-described terminal structures, it has the beneficial effects of any of the terminal structures in the first aspect, which will not be elaborated further here.

[0067] Furthermore, the bus body 112 itself is ring-shaped. By setting multiple spaced terminal structures, the circumferential structure of the bus body 112 can be utilized to make more reasonable use of the limited space and improve space utilization.

[0068] For the hook portion 114, such as Figure 4 As shown, the main components include a first hook 1142 and a second hook 1144 respectively disposed on the radially inner and radially outer sides of the busbar. The first hook 1142 allows the winding to be led outwards from the radially inner side of the busbar, and similarly, the second hook 1144 allows the winding to be led outwards from the radially outer side of the busbar. Multiple first hooks 1142 and second hooks 1144 can be provided on the busbar body 112, and the specific configuration can be flexibly adjusted according to the actual application scenario.

[0069] In a specific embodiment, such as Figure 5 and Figure 6 As shown, the terminal structure 100 for wiring is mainly welded to the controller substrate 118. Specifically, the controller substrate 118 is provided with mounting holes 1182 to facilitate the insertion of the terminal structure. When inserted, the protrusion structure 1044 is located exactly in the mounting hole 1182, thereby facilitating subsequent welding operations.

[0070] In another specific embodiment, such as Figure 3As shown, a support member 120 is provided, specifically on the fixing member 116. The second connecting plate 104 of the terminal structure extends outward through the hollow support member 120. The extended part has a protrusion structure 1044 to facilitate welding with the controller substrate 118 and realize normal electrical control. Example

[0071] like Figure 7 As shown, the motor structure 200 proposed in this embodiment includes a rotor structure 202 and a stator structure 204 coaxially arranged. The rotor structure 202 is disposed inside the stator structure 204, forming a motor structure 200 with an outer stator and an inner rotor. Under the action of the inner stator structure 204, a changing magnetic field is generated, thereby driving the rotor structure 202 to rotate. Furthermore, a busbar assembly is disposed at one end of the stator structure and is electrically connected to the stator structure, thereby realizing the control of the stator structure.

[0072] Furthermore, since the motor structure 200 includes any of the above-described busbar components 110 embodiments, it has the beneficial effects of any of the busbar components 110 in the first aspect, which will not be elaborated here. Example

[0073] like Figure 8 As shown, this embodiment proposes an electric power steering system 400, including a motor structure 200 as in any of the above possible embodiments. Therefore, the electric power steering system 400 provided in this embodiment has all the beneficial effects of the motor structure 200 provided in the above embodiments.

[0074] Among them, the Electric Power Steering (EPS) system is an electric power steering system that directly relies on the motor structure 200 to provide auxiliary torque power. Compared with the traditional hydraulic power steering (HPS) system, the EPS system has a simpler structure and more flexible assembly. It can save energy and protect the environment. Most modern vehicles are equipped with EPS systems.

[0075] The electric power steering system 400 can be implemented in several ways. One such implementation will be described in detail below. Specifically, in one implementation, the EPS system includes an electric power steering system and an auxiliary torque mechanism that generates auxiliary torque. This auxiliary torque assists the steering torque of the electric power steering system generated by the driver's operation of the steering wheel. This auxiliary torque reduces the driver's workload.

[0076] The electric power steering system 400 specifically includes a steering wheel 411, a steering shaft 412, a universal coupling 413, a rotating shaft 414, a rack and pinion mechanism 415, a rack and pinion shaft 416, and wheels 417 for left and right steering.

[0077] The auxiliary torque mechanism specifically includes a steering torque sensor 421, an automotive electronic control unit 422, a motor, and a reduction gear 423. Specifically, the steering torque sensor 421 detects the steering torque of the electric power steering system. The control unit 422 generates a drive signal based on the detection signal from the steering torque sensor 421. The motor generates an auxiliary torque corresponding to the steering torque based on the drive signal. The motor transmits the generated auxiliary torque to the electric power steering system via the reduction gear 423. Example

[0078] like Figure 9 As shown, the vehicle 300 proposed in this embodiment includes a vehicle body 302 and a motor structure 200 disposed within the vehicle body 302. The vehicle body 302 mainly provides a certain protection for the motor structure 200. Since the motor structure 200 is disposed within the vehicle body 302, it has the beneficial effects of any motor structure in the second aspect embodiment described above, which will not be elaborated further here.

[0079] In vehicles, the motor structure can serve as the main drive structure, i.e., an electric vehicle, or as the drive structure for other equipment inside the vehicle, such as a fan.

[0080] Of course, such as Figure 10 As shown, the motor structure 200 can be used to drive the electric power steering system 400 to achieve steering of the vehicle 300.

[0081] According to the terminal structure, bus assembly, motor structure and vehicle provided by the present invention, by limiting the projection of the first connecting plate and the second connecting plate, the space occupied by the entire terminal structure in a specific direction can be reduced, thereby reducing the unnecessary increase in the size of the motor and making it more conducive to the design concept of motor miniaturization.
