Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a motor output connector, a connection structure, a motor, an electric drive device, and a vehicle. Background Technology

[0002] The motor controller converts high-voltage direct current into alternating current and outputs it to the motor via connectors. Traditional connectors include cable / braided wire harnesses, but these occupy a significant amount of space. With the continuous development of motor technology, the demand for integration is increasing, as are the space requirements for layout. Using copper busbars instead of cable / braided wire harnesses can save space. In existing technology, the motor's output copper busbars and the motor controller's output copper busbars are connected by bolts, but this often results in loose bolts, leading to poor wiring contact. Utility Model Content

[0003] The inventors discovered that due to errors in the manufacturing process, it was difficult to completely align the bolt holes between the two copper busbars during installation, resulting in insecure bolt fixing and consequently poor circuit contact.

[0004] To ensure good wiring contact after installation, this utility model provides a motor output connector, including a conductive component. The conductive component is provided with a mating terminal, and the mating terminal is provided with a first through hole for passing through a bolt and adjusting the bolt position. The first through hole is used for axially mating with a third through hole on the current output terminal of the motor controller.

[0005] Since the position of the bolt relative to the first through hole can be adjusted, it is equivalent to providing more alignment holes for position compensation. When connecting the conductive parts to the output connector of the motor controller with bolts, the bolts can be installed at the position where the first through hole coincides with the bolt hole on the motor controller.

[0006] Furthermore, the first via is a strip-shaped or cross-shaped via.

[0007] The strip-shaped hole allows for adjustment of the bolt position along its length, while the cross-shaped hole allows for adjustment of the bolt position along two mutually perpendicular directions.

[0008] Furthermore, the mating terminal also has pins for connecting motor output wires.

[0009] Adding pins makes it easier to connect to the motor output wires, such as through soldering.

[0010] Furthermore, it also includes an insulating component, which has a terminal block corresponding to each of the mating terminals. The terminal block has a second through hole for inserting a bolt and adjusting the bolt position. The conductive component is mated with the insulating component, and the first through hole and the second through hole are axially connected.

[0011] The insulating component serves as a barrier, preventing other components inside the motor housing from being affected by high-voltage current. After the first and second through holes are axially connected, the bolts can move synchronously within the first and second through holes to adjust their positions.

[0012] Furthermore, the second through hole is a stepped hole, and a nut is provided in the large end hole of the stepped hole. The nut can move in at least one direction within the large end hole.

[0013] Compared to placing the nut outside the second through hole, placing the nut inside the large end hole of the second through hole results in a more compact structure, better integration, and guaranteed insulation performance.

[0014] Furthermore, the large end hole is a rectangular hole, the nut is a square nut, and the two opposite sides of the nut can slide along the two opposite hole walls of the large end hole.

[0015] After the bolt is screwed into the square nut, the position of the bolt can be easily adjusted by sliding the square nut, and the hole wall guides the sliding of the nut.

[0016] Furthermore, the width of the first through hole is smaller than the outer diameter of the nut.

[0017] After the first through hole and the second through hole are connected, the nut can be prevented from falling out of the second through hole because the width of the first through hole is smaller than the outer diameter of the nut.

[0018] Furthermore, the thickness of the nut is less than the depth of the large end hole.

[0019] The thickness of the nut is less than the depth of the large end hole, which allows the nut to move axially within the large end hole, thereby enabling adjustment of the bolt's axial position.

[0020] On the other hand, this utility model also provides a motor, including the above-mentioned motor output connector.

[0021] On the other hand, this utility model also provides a connection structure, including the above-mentioned motor output connector and a motor controller output connector; the motor controller output connector includes a current output terminal, which is connected to the mating terminal of the motor output connector by bolts.

[0022] The connection structure of this utility model ensures reliable bolt positioning and stable circuit connection.

[0023] Furthermore, the current output terminal is provided with a third through hole for passing through the bolt and adjusting its position, the third through hole being axially connected to the first through hole. The bolt position is adjusted using the third through hole, thus expanding the position compensation range.

[0024] Furthermore, the first through hole is used to adjust the bolt position along a first direction, and the third through hole is used to adjust the bolt position along a second direction perpendicular to the first direction. The bolt can be adjusted bidirectionally, expanding the position compensation range.

[0025] Furthermore, the third through hole is an oblong hole. The oblong hole can support adjustment of the bolt position along its length.

[0026] On the other hand, the present invention also provides an electric drive device, including a motor and a motor controller, wherein the motor and the motor controller are connected by the connection structure described above.

[0027] On the other hand, the present invention also provides a vehicle including the above-mentioned electric drive device.

[0028] This invention enables position compensation by adjusting the bolt position through the first through-hole, preventing loose bolt fixing due to misalignment of bolt holes and ensuring the reliability and stability of the circuit connection. Installing a nut in the second through-hole improves integration and insulation performance. The third through-hole further expands the position compensation range. Attached Figure Description

[0036] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Example 1

[0038] This embodiment uses the connection structure between a three-phase motor and a motor controller as an example for illustration.

[0039] In this embodiment, the connection structure includes a motor output connector and a motor controller output connector.

[0040] refer to Figure 1 and Figure 2 As shown, the motor output connector includes a conductive component 1, which has mating terminals. Each mating terminal has a first through hole 101 for passing through a bolt 4 and adjusting its position. In this embodiment, three mating terminals 1.1, 1.2, and 1.3 are provided for the UVW three-phase outputs of the motor, respectively.

[0041] Each mating terminal also has pin 111 for connecting the motor output wires. The added pins facilitate connection to the motor output wires, such as through soldering.

[0042] Since the position of bolt 4 relative to the first through hole 101 can be adjusted, it is equivalent to providing more alignment holes for position compensation. When connecting the conductive part 1 and the output connector of the motor controller with bolt 4, bolt 4 can be installed at the position where the first through hole 101 coincides with the bolt hole on the motor controller.

[0043] Preferably, the first through hole 101 is a strip-shaped hole or a cross-shaped hole. The strip-shaped hole can support the adjustment of the position of the bolt 4 along its length, and the cross-shaped hole can support the adjustment of the position of the bolt 4 along two mutually perpendicular directions.

[0044] refer to Figure 2 As shown, in this embodiment, the first through hole 101 is an oblong hole in a strip hole. The length direction of the oblong hole is along the transverse direction.

[0045] The motor output connector also includes an insulating component 2, which has a terminal block corresponding to each of the mating terminals. The terminal block has a second through hole for inserting the bolt 4 and adjusting the position of the bolt 4. The conductive component 1 is mated with the insulating component 2 (and can be fixed by hot riveting after mating), and the first through hole 101 is axially connected to the second through hole.

[0046] The insulating component 2 serves as an isolation and protection mechanism, preventing other components inside the motor housing from being affected by high-voltage current. After the first through hole 101 and the second through hole are axially connected, the bolt 4 can move synchronously in the first through hole 101 and the second through hole to adjust its position.

[0047] refer to Figure 5 and Figure 6 As shown, the motor controller output connector 3 includes a current output terminal, which is connected to the mating terminal of the motor output connector via a bolt 4. In this embodiment, three current output terminals 3.1, 3.2, and 3.3 are respectively provided for the three-phase outputs of the motor (UVW).

[0048] Preferably, the current output terminal is provided with a third through hole 301 for passing through the bolt 4 and adjusting the position of the bolt 4, and the third through hole 301 is axially connected to the first through hole 101. The position of the bolt 4 is adjusted by using the third through hole 301, thereby expanding the position compensation range.

[0049] Preferably, the first through hole 101 is used to adjust the position of the bolt 4 along a first direction (lateral), and the third through hole 301 is used to adjust the position of the bolt 4 along a second direction (longitudinal) perpendicular to the first direction.

[0050] Preferably, the third through hole 301 is an oblong hole. The oblong hole can support the adjustment of the position of the bolt 4 along its length.

[0051] During installation, first solder the three-phase output wires of the motor (UVW) to the mating terminals 1.1, 1.2 and 1.3 respectively. After soldering, the conductive component 1 is fixed inside the motor housing. Then, insert the current output terminal of the motor controller output connector 3 into the motor housing. Insert bolts 4 sequentially into the third through hole 301 of the current output terminal, the first through hole 101 of the mating terminal, and the second through hole of the insulating component 2. Adjust the position of bolts 4 in the first through hole 101 and the second through hole, and / or the third through hole 301, so that the third through hole 301 is axially mated with the first through hole 101 and the second through hole, and the axis of bolts 4 is parallel or coincident with the axis of the third through hole 301, the first through hole 101, and the second through hole. Then, tighten bolts 4 by using the nut (which can be made of insulating material, such as a plastic nut) on the outside of the second through hole, thus completing the fixing of the current output terminals 3.1, 3.2, and 3.3 to the mating terminals 1.1, 1.2, and 1.3, respectively.

[0052] Example 2

[0053] refer to Figure 3 and Figure 4As shown, the difference between this embodiment and embodiment 1 is that the second through hole 201 on the insulating component 2 is a stepped hole, and a nut 2.1 is provided in the large end hole of the stepped hole. The nut 2.1 can move in at least one direction in the large end hole.

[0054] Compared to placing the nut 2.1 outside the second through hole 201, placing the nut 2.1 inside the large end hole of the second through hole 201 results in a more compact structure, better integration, and guaranteed insulation performance.

[0055] Preferably, the large end hole is a rectangular hole, and the nut 2.1 is a square nut 2.1, with the two opposite sides of the nut 2.1 capable of sliding along the two opposite hole walls of the large end hole. After the bolt 4 is screwed into the square nut 2.1, the position of the bolt 4 can be easily adjusted by sliding the square nut 2.1, and the hole wall guides the sliding of the nut 2.1.

[0056] Preferably, the width of the first through hole 101 is smaller than the outer diameter of the nut 2.1. After the first through hole 101 and the second through hole 201 are connected, the nut 2.1 can be prevented from falling out of the second through hole 201 because the width of the first through hole 101 is smaller than the outer diameter of the nut 2.1.

[0057] Preferably, the thickness of the nut 2.1 is less than the depth of the large end hole. This allows the nut 2.1 to move axially within the large end hole, thereby enabling adjustment of the axial position of the bolt 4.

[0058] This embodiment can simultaneously adjust the position of bolt 4 in the horizontal, vertical and axial directions to achieve position compensation.

[0059] Example 3

[0060] The difference between this embodiment and embodiment 2 is that it has 4 docking terminals, three of which are used to connect the three-phase output lines (UVW) of the motor, and the remaining one is used to connect the neutral point output line of the motor.

[0061] It should be noted that for motors with a neutral point output line, the motor controller output connector 3 can be equipped with 4 current output terminals at the same time, or only 3 current output terminals can be set, and an independent connector can be added with a separate current output terminal on the connector.

[0062] In addition, for single-phase motors, only two mating terminals need to be set on the motor output connector, and correspondingly, only two current output terminals need to be set on the motor controller output connector 3, which are used to connect the positive and negative poles respectively.

[0063] When the motor output connector has only one mating terminal, it can be used to connect only the neutral line of the motor.

[0064] Example 4

[0065] This embodiment provides an electric drive device, including a motor and a motor controller, wherein the motor and the motor controller are connected by any of the connection structures described in embodiments 1 to 3.

[0066] This embodiment also provides a vehicle, including the electric drive device of this embodiment.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
