[0047] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0048] In the prior art, the busbar device usually includes three-phase busbars and a shell supporting the three-phase busbars. Since the lead wires of each phase of the stator winding of the flat wire motor usually extend in the axial direction of the flat wire motor, the busbar usually also includes an axially extending portion. The lead wires of each phase of the stator winding are arranged side by side close to the axially extending portion of the busbar and are welded together to form an electrical connection. In the case of the flat wire motor being used as a drive motor of a vehicle, due to the vibration of the vehicle, there is a risk of the lead wires of the flat wire motor being fractured from the welding of the busbar device, thereby causing the vehicle to run unstably.

[0049] It should be noted that the three-phase lead wires are respectively a V-phase lead wire, a U-phase lead wire and a W-phase lead wire.

[0050] In order to overcome the defects in the prior art, the first mounting member and the second mounting member of the embodiments of the present application are arranged opposite to each other to form a first clamping area, the first clamping area is used to clamp the lead wire to limit the offset of the lead wire relative to the first mounting member or the second mounting member, thereby improving the connection stability of the lead wire, reducing the occurrence of the fracture of the welding between the lead wire and the busbar, and thereby improving the anti-vibration performance of the lead wire.

[0051] It should be noted that in the case of vehicle vibration, the first clamping area clamps the lead-out wire, which can limit the offset amplitude of the lead-out wire relative to the first mounting member or the second mounting member, so as to reduce the occurrence of the swing of the lead-out wire relative to the busbar, thereby reducing the occurrence of fatigue failure of the lead-out wire or the welding position of the lead-out wire and the busbar, thereby reducing the risk of welding fracture of the lead-out wire and the busbar.

[0052] Therefore, the motor provided by the embodiment of the present application can solve the problem of the risk of welding fracture of the lead-out wire of the flat wire winding motor and the unstable operation of the vehicle.

[0119] It should be noted that the buffer 300 has a plurality of different arrangement positions, which will be described in turn.

[0120] In one possible implementation, the buffer 300 is arranged on the hole wall of the through hole 203 towards the side close to the first extension part 101, and the buffer 300 abuts against the lead-out wire 500, and the buffer 300, the lead-out wire 500 and the first extension part 101 are arranged adjacent to each other in the first direction X.

[0121] It can be understood that the arrangement of the buffer 300 can make the lead-out wire 500 and the hole wall of the through hole 203 be connected flexibly, so as to reduce the stress concentration between the lead-out wire 500 and the hole wall of the through hole 203 in the case of limiting the deviation of the lead-out wire 500 in the first direction X, thereby protecting the lead-out wire 500.

[0122] In another possible implementation, the buffer 300 is arranged on the first extension part 101 towards the side close to the lead-out wire 500, and the buffer 300 abuts against the lead-out wire 500, and the lead-out wire 500, the buffer 300 and the first extension part 101 are arranged adjacent to each other in the first direction X.

[0123] It can be understood that the buffer 300 is arranged to enable the flexible connection between the lead-out wire 500 and the first extension 101, so as to reduce the stress concentration between the lead-out wire 500 and the first extension 101 in the case of the displacement of the lead-out wire 500 along the first direction X, thereby protecting the lead-out wire 500.

[0124] In addition, in another possible implementation, two buffers 300 are arranged, one of which is arranged on the hole wall of the through hole 203 towards the side close to the first extension 101, and the other of which is arranged on the first extension 101 towards the side close to the lead-out wire 500, the lead-out wire 500 being located between the two buffers 300 and abutting against the two buffers 300 respectively.

[0125] It can be understood that the buffer 300 is arranged to enable the flexible connection between the lead-out wire 500 and the first extension 101 and the hole wall of the through hole 203, so as to reduce the stress concentration between the lead-out wire 500 and the first extension 101 and the hole wall of the through hole 203 in the case of the displacement of the lead-out wire 500 along the first direction X, thereby protecting the lead-out wire 500.

[0126] It can be understood that the arrangement position of the buffer 300 is not limited and can be selected according to actual use requirements.

[0127] It should be noted that the motor provided in any of the above embodiments can be an alternating current induction motor, a permanent magnet synchronous motor, a flat wire winding motor, or other motors provided on a vehicle, which is not limited herein and can be selected and replaced according to actual use requirements.

[0128] It should be noted that the terms "one embodiment", "an embodiment", "exemplary embodiment", "some embodiments", etc. in the specification mean that the described embodiments can include a specific feature, structure or characteristic, but not necessarily every embodiment. In addition, such phrases do not necessarily refer to the same embodiment. In addition, when a specific feature, structure or characteristic is described in combination with an embodiment, it is within the knowledge of those skilled in the art to realize such feature, structure or characteristic in combination with other embodiments described explicitly or implicitly.

[0129] Generally, the terms should be understood at least partly by the use in the context. For example, at least partly according to the context, the term "one or more" used in the specification can be used to describe any feature, structure or characteristic in the singular sense, or can be used to describe a combination of features, structures or characteristics in the plural sense. Similarly, at least partly according to the context, terms such as "a" or "said" can be understood to convey singular usage or plural usage.

[0130] It should be readily understood that "on," "over," and "above" in the present application should be interpreted in the broadest manner such that "on" means not only "directly on" but also includes the meaning of "on" with intervening features or layers therebetween, and "over" or "above" includes not only the meaning of "over" or "above" but also the meaning of "over" or "above" with no intervening features or layers therebetween (i.e., directly on).

[0131] In addition, spatially relative terms, such as "beneath", "below", "lower", "above", "upper", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. The devices can be otherwise oriented (rotated 90° or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0132] Finally, it should be noted that the above-described embodiments are merely intended for describing and illustrating, not limiting, the technical solutions of the present application; even though the present application has been described in detail with reference to the above-described embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the above-described embodiments, or make equivalent replacements to some or all of the technical features thereof; and such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
