Technical Field

The utility model belongs to the technical field of vehicle components, and particularly relates to a motor wire holder, a motor system and a vehicle.

Background

With the development of society, energy crisis caused by non-renewable energy sources such as fossil energy sources is increasingly highlighted, and environmental pollution caused by burning fossil energy sources also has a bad influence on the global environment of the earth. Automobiles are important consumption sources of fossil energy, and new energy automobiles are becoming popular in order to reduce the use of fossil energy and improve the energy utilization rate. The core power component of the new energy automobile comprises a battery pack and a motor, and connection between the battery pack and the motor is realized through a wire holder arranged on the motor.

The wiring seat mainly comprises a base and a conductive copper column, the base is generally fixed on the motor main body through a threaded connecting piece, the conductive copper column is provided with an inner screw hole, and the end of a high-voltage wiring harness of the motor and the end of a three-phase output wiring harness at the end of a controller are overlapped between the conductive copper column and a bolt cap of the fixing bolt through the cooperation of the conductive copper column and the fixing bolt, so that conductive connection between wiring harnesses is realized. In general, the wire holder is used as a structure for supporting the outgoing wires of the motor, so that the current in the battery pack can reach the motor through the controller to provide power for the operation of the motor, the wiring area between the wire harnesses can be kept stable, and the problem that the motor burns out due to the falling off or the electrical short circuit of the wire harnesses in the operation process of the motor is prevented.

At present, a plurality of conductive copper bars of a motor main body are welded with a hard copper bar, connecting holes corresponding to the fixing bolts are formed in the copper bar, and the conductive copper bars are extruded between the conductive copper bars and the fixing bolts. In consideration of manufacturing and assembly errors between the base and the motor main body, manufacturing deviations and welding angle deviations between the copper bars and the outlet ends of the motor main body, positions of the conductive copper columns and the corresponding ends of the copper bars in the axial direction of the conductive columns are deviated, and due to the fact that the copper bars are rigid members, the probability of non-tight adhesion between the conductive copper columns and the copper bars after assembly is high due to the deviation of the positions, and local overheating phenomenon is easy to occur due to the fact that the conductive contact area is insufficient. In order to solve the problem, the prior art mostly adopts soft copper bars or braided copper wires, and the problem of poor adhesion with the conductive copper column can be improved by virtue of the variable capability of the lead-out structure, but the use cost of the lead-out structure is higher, the size is larger, the requirement on the assembly space is severe, and the design requirements on the light weight and the compactness of the motor are negatively influenced.

In this embodiment, the pushing end 301 always abuts against the first limiting surface 2021, and the first limiting surface 2021 is an inclined surface, so that the guiding terminal 2 extends along the first path along the direction away from the elastic pushing structure 3 under the extrusion action of the pushing end 301. The embodiment provides the pushing acting force perpendicular to the first path, the whole arrangement of the elastic pushing structure 3 can be distributed along the direction perpendicular to the first path, and on the premise of ensuring the pushing effect, the situation that too much space outside the base 1 is occupied is avoided, and the size of the motor wire holder is more compact and small on the first path.

The avoidance groove 102 of the embodiment plays a role in protecting and supporting the elastic pushing structure 3 and the limiting end 202, and prevents interference between the elastic pushing structure 3 and the limiting end 202 and the motor main body after assembly from influencing normal use.

Since the fastener 4 and the fastening hole 203 are mostly in a threaded fit structure, the fastener needs to be screwed during assembly, in order to avoid the conductive terminal 2 rotating due to screwing the fastener 4, in some embodiments, one of the conductive terminal 2 and the guide channel 101 is provided with a circumferential limit protrusion 6, the other of the conductive terminal 2 and the guide channel 101 is provided with a circumferential limit groove 7 corresponding to the circumferential limit protrusion 6, and the circumferential limit protrusion 6 and the circumferential limit groove 7 are slidably fitted along the first path. The sliding fit of the circumferential limiting protrusion 6 and the circumferential limiting groove 7 does not affect the movement of the conductive binding post 2 on the first path, meanwhile, the problem of the rotation of the conductive binding post 2 is avoided, the circumferential displacement of the conductive binding post 2 is not required to be controlled by a human hand during assembly, and the assembly difficulty is further reduced.

The first step surface 110 and the second step surface 120 divide the mounting area of the base 1 and the motor main body and the connection area of the base 1 and the conductive copper bar 5, and form a staggered distribution structure on the first path, so that the interference of the mounting fasteners to the connection of the conductive copper bar 5 and the controller wire harness is avoided.

On the basis of the above embodiment, referring to fig. 1 to 4, a plurality of guide channels 101 distributed along a second path are provided on the second step surface 120, and a lightening hole 121 is provided between two adjacent guide channels 101, so as to reduce the amount of material used for the base 1, and fit the design requirement of light weight; in order to reinforce the region where the lightening hole 121 is located, the structural strength of the whole base 1 is ensured, the lightening hole 121 is spanned with a reinforcing rib 140 along a third path, one end of the reinforcing rib 140 extends from the second step surface 120 to the first step surface 110 (as shown in fig. 3), and the other end extends to the edge of the side of the base 1 facing away from the second step surface 120 (as shown in fig. 4). Wherein the second path is perpendicular to the first path and the third path is perpendicular to the first path and the second path.

More specifically, referring to fig. 1 to 4, a plurality of lightening holes 121 are spaced apart along the third path between two adjacent guide channels 101. The weight reducing holes 121 are arranged in a scattered manner in the embodiment, so that the strength of the base 1 is prevented from being weakened due to the overlarge open area of the single hole.
