DETAILED DESCRIPTION

[0021] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] In this document, reference to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. Those skilled in the art will understand that the embodiments described herein can be combined with other embodiments.

[0023] The electric drive assembly and the vehicle provided by the present application will be described in detail below in combination with the embodiments.

[0024] Please refer to Figures 1 to 3 , Figure 1 Fig. 1 is a structural schematic view of an embodiment of an electric drive assembly of the present application; Figure 2 Fig. 2 is a structural schematic view of an embodiment of a wiring harness buckle of the present application; Figure 3is a structural schematic diagram of an embodiment of a shell of the present application. The present application provides an electric drive assembly 100, which comprises a shell 1, a motor (not shown in the figure) and a wire harness buckle 2. The motor is installed in the shell 1. The motor can comprise a stator and a rotor. The wire harness buckle 2 comprises a tie 21 and a fixing seat 22. The tie 21 is connected to the fixing seat 22. The fixing seat 22 is directly or indirectly connected to the shell 1. The tie 21 is used to bundle the wire harness of the electric drive assembly 100.

[0025] Specifically, the wire harness is a conductor used to transmit signals, power and the like in the electric drive assembly 100. The tie 21 is generally in the form of a strip. After the tie 21 bundles the wire harness, the wire harness is not easy to move relative to the tie 21, and thus is not easy to shake in the electric drive assembly 100. After the fixing seat 22 is connected, the position of the wire harness buckle 2 relative to the shell 1 remains stationary. The fixing seat 22 can be directly connected to the shell 1, for example, the shell 1 can be provided with a mounting structure, and the fixing seat 22 is directly connected to the mounting structure. The fixing seat 22 can also be indirectly connected to the shell 1, for example, the fixing seat 22 can be first connected to another structure, and the other structure is then fixed to the shell 1.

[0026] Through the above arrangement, the tie 21 bundles and arranges the wire harness in the electric drive assembly 100, and is fixed to the shell 1 through the fixing seat 22. The wire harness is stably fixed and is not easy to shake in the electric drive assembly 100 to interfere with other structures, thereby enhancing the stability of the electric drive assembly 100.

[0027] In an embodiment, the material of the wire harness buckle 2 is a high molecular polymer material, such as polytetrafluoroethylene (PTFE) and the like. When the working condition of the electric drive assembly 100 is harsh, the common resin material can be easy to become brittle and decompose, resulting in failure of the wire harness buckle 2. In the present embodiment, the material of the wire harness buckle 2 is set to polytetrafluoroethylene, which is beneficial to resist the high oil temperature, vibration and other harsh working conditions in the electric drive assembly 100, so that the electric drive assembly 100 is more stable.

[0028] In an embodiment, the shell 1 comprises an outer end face 11 and a receiving cavity (not shown in the figure). The outer end face 11 can be an end face of the outer surface of the shell 1 perpendicular to the rotor axis. The outer end face 11 can have more wire harnesses. The outer end face 11 is provided with a mounting hole 111. The mounting hole 111 and the motor can be located on opposite sides of the outer end face 11. The motor is installed in the receiving cavity. The fixing seat 22 is fixed to the mounting hole 111. The tie 21 bundles the wire harness at the outer end face 11.

[0029] Through the above arrangement, the wire harness buckle 2 is arranged at the outer end face 11, which can better arrange the more wire harnesses at the outer end face 11 of the electric drive assembly 100, and can arrange the important wire harnesses related to the operation of the motor at the outer end face 11, so that they are not easy to interfere with other structures, which is beneficial to improve the stability of the electric drive assembly 100.

[0030] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of an embodiment of the insulating seat of the present application. In an embodiment, the mounting hole 111 includes a mounting blind hole 1111. The mounting blind hole 1111 is a blind hole that does not penetrate the shell 1. The motor includes a rotor. The outer end surface 11 of the shell 1 corresponding to the area of the rotor is provided with the mounting blind hole 1111. That is, the blind hole is arranged close to the rotor. The wire harness buckle 2 includes a first wire harness buckle 2a2. The first wire harness buckle 2a2 includes a first cable tie 21a and a first fixing seat 22a. The first cable tie 21a is connected to the first fixing seat 22a. The first fixing seat 22a is fixed to the mounting blind hole 1111. In this way, by arranging the mounting blind hole 1111 on the outer end surface 11, compared with arranging a through hole, the first fixing seat 22a can be fixed, and does not need to be in contact with the high working condition environment in the accommodation cavity, which is conducive to improving the service life of the first fixing seat 22a. Moreover, the wire harness of the rotor or its associated structure can be directly fixed by the first wire harness buckle 2a2 close to it, and the possibility of shaking is reduced as much as possible, and the electric drive assembly 100 runs stably.

[0031] The way in which the first fixing seat 22a is fixed to the mounting blind hole 1111 can be clamping, screwing, interference connection, etc., which is not limited here.

[0032] In an embodiment, the electric drive assembly 100 includes a resolver sensor 4. The resolver sensor 4 is used to detect the position of the rotor of the motor. The resolver sensor 4 is mounted on the outer end surface 11 corresponding to the position of the rotor. The resolver sensor 4 is connected with a first wire harness 41. The first wire harness 41 extends along the outer end surface 11. The first wire harness 41 can be connected to a motor controller. The first cable tie 21a bundles the first wire harness 41.

[0033] Through the above arrangement, the resolver sensor 4 can effectively perceive and transmit the position information of the rotor in real time, and facilitate timely adjustment when the rotor deviates. Moreover, the first wire harness 41 is bundled and fixed by the first cable tie 21a, which improves the reliability of the first wire harness 41, so that the position signal of the rotor is not easily lost due to loosening of the first wire harness 41, and the electric drive assembly 100 runs stably.

[0034] In an embodiment, the electric drive assembly 100 further includes an insulating seat 3, and the insulating seat 3 is mounted on the outer end surface 11. The motor includes a stator, and the insulating seat 3 is arranged corresponding to the area where the stator is located. The mounting hole 111 further includes a mounting through hole 1112. The mounting through hole 1112 is arranged on the insulating seat 3. The mounting through hole 1112 penetrates the insulating seat 3. The wire harness buckle 2 further includes a second wire harness buckle 2b. The second wire harness buckle 2b includes a second cable tie 21b and a second fixing seat 22b. The second cable tie 21b is connected to the second fixing seat 22b. The second fixing seat 22b is fixed to the mounting through hole 1112. The second cable tie 21b is used to bundle the wire harness at the insulating seat 3.

[0035] Through the above arrangement, the second wire harness buckle 2b can better organize the more wire harnesses at the insulating seat 3 of the electric drive assembly 100. For example, when the insulating seat 3 is arranged close to the stator, the second wire harness buckle 2b can better organize the wire harnesses of the stator or its associated structure, so that it is not easy to interfere with other structures, which is conducive to improving the stability of the electric drive assembly 100.

[0036] The manner in which the above-mentioned second fixing seat 22b is fixed to the mounting hole 1112 can be clamping, screwing, interference connection, etc., which is not limited here.

[0037] In an embodiment, the electric drive assembly 100 includes a thermal sensor. The thermal sensor can be used to detect the temperature of the stator of the motor. The thermal sensor is arranged in the accommodation cavity. The thermal sensor is connected with a second wire harness (not shown in the figure). The second wire harness at least partially extends to the outer end face 11. The second cable tie 21b binds the second wire harness located at the outer end face 11.

[0038] Through the above arrangement, the thermal sensor can effectively perceive and transmit the position of the stator in real time, which is convenient for timely adjustment when the stator is overheated. And the second wire harness is pulled out to the outer end face 11 and then bound and fixed by the second cable tie 21b, so that the second wire harness buckle 2b does not have to be directly located in the accommodation cavity, which is conducive to improving the service life of the second wire harness buckle 2b, and also improves the reliability of the second wire harness, so that the temperature signal of the stator is not easy to be lost due to the loosening of the second wire harness, and the electric drive assembly 100 runs stably.

[0039] In an embodiment, a gap is formed between the insulating seat 3 and the outer end face 11. That is, the insulating seat 3 is at least partially spaced from the outer end face 11. The shell 1 is provided with an opening 12. The opening 12 communicates the accommodation cavity and the external environment at the outer end face 11. The second wire harness is pulled out from the accommodation cavity to the outer end face 11 through the opening 12 and extends in the gap. That is, the second wire harness is always entirely on the side of the insulating seat 3 facing the outer end face 11. The second fixing seat 22b is fixed to the side of the insulating seat 3 facing the outer end face 11. The second cable tie 21b is located in the gap and binds the second wire harness at the gap.

[0040] Through the above arrangement, the second wire harness and the second wire harness buckle 2b are both located in the gap formed by the insulating seat 3 and the outer end face 11, and the second wire harness is not only fixed by the second wire harness buckle 2b, but also the second wire harness and the second wire harness buckle 2b can both be covered by the insulating seat 3, so that they are more difficult to interfere with other structures, further improving the stability of the electric drive assembly 100.

[0041] In an embodiment, along the direction from the insulating seat 3 to the outer end face 11, the orthographic projection of the mounting hole 1112 at least partially overlaps the opening 12. Thus, the second wire harness pulled out from the opening 12 can be immediately fixed by the second wire harness buckle 2b, and the second wire harness is not easy to interfere with the edge of the insulating seat 3 or the shell 1.

[0042] In an embodiment, the fixing base 22 comprises a main body 23 and a cable tie 21. The main body 23 is provided with a cable tie through hole 231. The main body 23 is provided with a support column 232 on one side. The support column 232 is provided with a groove 2321 along the axis. That is, the support column 232 is provided in a hollow manner. The support column 232 is provided with a plurality of clamps 2322 on the outer peripheral surface thereof and spaced apart along the axial direction of the support column 232. The clamps 2322 can be fir tree-shaped clamps 2322. The clamps 2322 can be elastically deformed. The hardness of the support column 232 is greater than the hardness of the clamps 2322. The support column 232 can be provided with a hardness that is not easy to elastically deform.

[0043] The force required for the clamps 2322 to elastically deform along the insertion direction is less than the force required for the clamps 2322 to elastically deform along the direction opposite to the insertion direction. The insertion direction is the direction in which the clamps 2322 point to the main body 23. When the fixing base 22 is installed along the insertion direction, the clamps 2322 are pressed to elastically deform along the insertion direction, and are fitted to the outer peripheral surface of the support column 232, so that the fixing base 22 can continue to move along the insertion direction. When the fixing base 22 moves along the direction opposite to the insertion direction, the clamps 2322 are not easy to elastically deform along this direction, and the clamps 2322 remain expanded radially along the support column 232 to form a limit, so that the fixing base 22 cannot continue to move along the direction opposite to the insertion direction. That is, the clamps 2322 allow the fixing base 22 to be installed in one direction and locked in the opposite direction.

[0044] The cable tie 21 is provided with a locking portion 211 at one end and a plurality of locking buckles 212 at the other end. The locking buckles 212 can be spaced apart to form a plurality of gears at the other end. The cable tie 21 passes through the cable tie through hole 231, and then the locking buckles 212 are locked to the locking portion 211 to form a ring-shaped fixing cavity. The fixing cavity is used for bundling the wire harness. When the locking buckles 212 are inserted into the locking portion 211, no interference is generated between the locking buckles 212 and the locking portion 211. When the locking buckles 212 move in the direction of pulling out the locking portion 211, the locking buckles 212 interfere with the locking portion 211 and cannot be pulled out. The specific structure of the locking buckles 212 and the locking portion 211 can achieve one-way locking, for example, the specific structure can refer to the structure of the clamps 2322 described above, which is not limited here.

[0045] Through the above arrangement, the relatively hard support column 232 can provide stable support for the clamps 2322, so that the fixing base 22 is not easy to accidentally deform and fall off. In addition, the support column 232 is provided with the groove 2321, so that the wire harness buckle 2 is lighter as a whole, saves materials, and the support column 232 can also be slightly deformed under necessary circumstances, and is not easy to break, which balances the support degree and adaptability.

[0046] Further, the main body 23 further comprises a limiting locking portion 233. The limiting locking portion 233 extends radially along the support column 232, and the distance of the limiting locking portion 233 to the support column 232 gradually decreases along the insertion direction. The limiting locking portion 233 is elastic. That is, when the main body 23 is inserted into the corresponding mounting structure along the insertion direction, the limiting locking portion 233 is pressed along the insertion direction and accumulates elastic potential energy. Then the limiting locking portion 233 tries to recover and applies an elastic force in the opposite direction to the mounting structure, so that the fixed seat 22 is subjected to a force in the opposite direction of the insertion direction, driving the fixed seat 22 to move in this direction. However, the fixed seat 22 is limited by the clamping portion 2322 and cannot be separated from the mounting structure until the elastic force of the limiting locking portion 233 and the limiting force of the clamping portion 2322 are balanced, so that the clamping portion 2322 is tightly abutted on the mounting structure, reducing the gap between the clamping portion 2322 and the mounting structure, and enhancing the sealing and firmness of the fixed seat 22 after installation.

[0047] Through the above arrangement, the fixed seat 22 can be naturally locked in the mounting position by the limiting locking portion 233 after installation, improving the installation firmness and sealing, and being beneficial to enhancing the stability of the electric drive assembly 100.

[0048] Another aspect of the present application provides a vehicle. The vehicle comprises the electric drive assembly 100 in any of the above embodiments. The electric drive assembly 100 in the present embodiment is the electric drive assembly 100 described in the above embodiments, which will not be described again herein. Thus, the wire harness in the electric drive assembly 100 can be well arranged and fixed, and is not easy to interfere and cause abnormal operation of the electric drive assembly 100, and the vehicle has stable use performance.

[0049] The terms "first", "second", "third", etc. in the present application are only for descriptive purpose, and cannot be understood as indicating the number of the technical features. Thus, the features with "first", "second", "third" can explicitly or implicitly include at least one of the features.
