[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0057] This application provides a motor end cover, please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the exploded structure of the motor end cover. Figure 2 It is a schematic diagram of the three-dimensional structure of the motor end cover.

[0058] The motor end cover includes an end cover body 1, an inductor 2 and a brush 3, and a cavity structure 11 is arranged on the end cover body 1. The inductor 2 is installed on the end cover body 1 and arranged outside the cavity structure 11. The brush 3 is electrically connected to the inductor 2, and is also installed on the end cover body 1 and arranged in the cavity structure 11, so that the inductor 2 and the brush 3 are arranged in layers and isolated from each other. The cavity structure 11 ensures the opening space of the brush 3, and does not interfere with the inductor 2 arranged outside the cavity structure 11 during the assembly and opening process of the brush 3, thereby simplifying the assembly process and improving the assembly efficiency. In the process of assembling the motor end cover to the motor, since the inductor 2 does not interfere with the opening of the brush 3, the operation is relatively simple, and the brush 3 can be opened by a manipulator instead of manually controlling the opening of the brush 3, so that the rotor converter of the motor is installed between the brushes 3, and the electrical connection between the motor end cover and the rotor converter is realized, which simplifies the assembly process and improves the degree of automation.

[0059] For example, see Figure 1 and Figure 2 The end cover body 1 is cylindrical, the cavity structure 11 is opened in the middle area of ​​the end cover body 1, and penetrates the end cover body 1 along the axial direction of the end cover body 1, the inductor 2 is arranged outside the cavity structure 11, and the brush 3 is arranged in the cavity structure 11, and the two are isolated from each other. The brush 3 can be opened and contracted within the range of the cavity structure 11, and in this process, it will not contact the inductor 2 arranged outside the cavity structure 11, and no mutual interference will be formed.

[0060] In some embodiments, see Figure 1 and Figure 2 The motor end cover includes two inductors 2 and two brushes 3. The two inductors are respectively arranged on opposite sides of the cavity structure 11, and each inductor 2 is connected to the corresponding brush 3. The two brushes 3 supply power to the motor rotor so that the motor can operate normally. The inductors 2 electrically connected to the brushes 3 can improve the stability of the motor operation and reduce interference. The two inductors 2 are symmetrically distributed on opposite sides of the cavity structure 11, so that the filter circuit can be more balanced and it is not easy to have an extremely weak point due to asymmetry, which affects the filtering effect.

[0061] For example, see Figure 1 and Figure 2The inductor 2 includes a first inductor 21 and a second inductor 22, and the brush 3 includes a first brush 31 and a second brush 32. The first inductor 21 and the first brush 31 are connected via a connector 4, and the second inductor 22 and the second brush 32 are connected via another connector 4. The connectors 4 used are the same, so that the two connectors 4 and the first brush 31 and the second brush 32 are symmetrically distributed, further improving the filtering effect.

[0062] In addition, by adopting a symmetrical structure and using similar accessories in the symmetrical structure, the investment in parts and molds for the assembly device can be reduced, and the difficulty of installation can also be simplified.

[0063] In some embodiments, see Figure 1 and Figure 2 The end cover body 1 is also provided with two receiving grooves 12, which are used to receive two inductors 2 respectively, and the groove walls 121 of the two receiving grooves 12 surround at least a part of the cavity structure. Each groove wall 121 is located between adjacent inductors 2 and brushes 3.

[0064] That is, the two inductors 2 are respectively arranged in two receiving grooves 12, and the receiving grooves 12 can provide a limiting effect on the inductors 2, thereby improving the installation stability of the inductors 2. And the groove wall located between the adjacent inductors 2 and brushes 3 can separate the adjacent inductors 2 and brushes 3, so that the inductors 2 and brushes 3 do not directly contact each other, thereby reducing the interference between the two. In some embodiments, please refer to Figure 1 and Figure 2 The motor end cover also includes a connector 4, which includes a connecting portion 41 and a bearing portion 42 that are connected to each other. The connecting portion 41 is connected to one end of the inductor 2, and the bearing portion 42 is connected to the brush 3. The inductor 2 and the brush 3 are connected by the connector 4 to fix the brush 3, and the connector 4 can realize the electrical connection between the brush 3 and the inductor 2. There is no need to set up an additional brush braid structure, and there is no need to manually weld the inductor 2 and the brush 3 with the brush braid during the assembly process, which improves the assembly efficiency and facilitates the realization of automated assembly.

[0065] In some embodiments, see Figure 1 and Figure 2 , the end cover body 1 is provided with a limiting groove 16. Among them, the bottom of the connecting part 41 is installed in the limiting groove 16, the top of the connecting part 41 extends out of the limiting groove 16, and the top of the connecting part 41 is provided with a first touch welding terminal 411, and one end of the inductor 2 is connected to the first touch welding terminal 411. By providing the first touch welding terminal 411 on the connecting part 41, it is not necessary to pre-weld the connecting part 4 and the inductor 2 during the assembly process of the motor end cover. The inductor 2 and the connecting part 4 can be directly assembled to the end cover body and then welded by touch welding, which simplifies the assembly steps and facilitates automated installation.

[0066] In some embodiments, see Figure 4 The bearing part 42 is connected to one side of the connecting part 41. The bearing part 42 is an elastic arm structure and extends into the cavity structure 11. The brush 3 is installed on the bearing part 42. In order to ensure the effective electrical connection between the brush 3 and the rotor converter of the motor, a certain pre-tightening force is required between the multiple brushes 3 so that the brush 3 can be attached to the surface of the rotor converter. And in the process of installing the rotor converter to the motor end cover, the brush 3 needs to be opened. By setting the bearing part 42 as an elastic arm structure, the brush 3 can be controlled to open during the assembly of the rotor converter. After the rotor converter is assembled, the elastic arm structure can provide a restoring force to make the brush 3 stick to the surface of the rotor converter.

[0067] In some embodiments, see Figure 4 The bearing part 42 is provided with a mounting hole 421, and the brush 3 is mounted on the bearing part 42 through the mounting hole 421, and then the brush 3 is fixed on the connecting member 4, and the installation process is simple. The brush 3 arranged on the bearing part 42 is electrically connected to the inductor 2 through the bearing part 42 and the connecting part 41.

[0068] In some embodiments, see Figure 4-Figure 5 The motor end cover also includes two conductive members 5. The conductive members 5 are partially enclosed in the end cover body 1, and the two conductive members 5 are arranged at intervals. Among them, the conductive member 5 is provided with a power terminal 511 and a second touch welding terminal 512, and the power terminal 511 and the second touch welding terminal 512 are respectively arranged on opposite sides of the end cover body 1. The other end of the inductor 2 is connected to the second touch welding terminal 512, and the power terminal 511 is configured to be electrically connected to an external power source.

[0069] The first conductive member 51 and the second conductive member 52 are partially covered in the end cover body 1, and the first conductive member 51 and the second conductive member 52 are spaced apart. That is, part of the first conductive member 51 and the second conductive member 52 are covered in the end cover body 1, and part of the first conductive member 51 and the second conductive member 52 are exposed outside the end cover body 1, and the first conductive member 51 and the second conductive member 52 do not contact each other.

[0070] For example, see Figure 4-Figure 6 The conductive member 5 includes a first conductive member 51 and a second conductive member 52 . The structures of the first conductive member 51 and the second conductive member 52 may be the same and are symmetrically distributed on the end cover body 1 .

[0071] The other end of the inductor 2 is connected to the second touch welding terminal 512. Through the second touch welding terminal 512, the other end of the inductor 2 can be connected to the conductive member 5 by touch welding. The power supply terminals 511 on the two conductive members 5 are configured to be connected to an external power supply.

[0072] Exemplarily, one end of the first inductor 21 is connected to the first brush 31 through the connector 4, and the other end is connected through the second soldering terminal 512 on the first conductive member 51; one end of the second inductor 22 is connected to the second brush 32 through the connector 4, and the other end is connected through the second soldering terminal 512 on the second conductive member 52; the power supply terminals 511 on the first conductive member 51 and the second conductive member 52 can be connected to the input and output ends of an external power supply, respectively, thereby forming a current loop of the first conductive member 5 → first inductor 21 → first brush 31 → rotor converter → rotor → second brush 32 → second inductor 22 → second conductive member 52, thereby achieving the purpose of powering the motor rotor.

[0073] In some embodiments, see Figure 3 , Figure 4 and Figure 7 , the first butt-welding terminal 411 and the second butt-welding terminal 512 are respectively provided with a first groove 4111 and a second groove 5121. The first welding portion 221 and the second welding portion 222 are respectively provided at opposite ends of each inductor 2. Among them, the first welding portion 221 is configured to be embedded in the first groove 4111, and the second welding portion 222 is configured to be embedded in the second groove 5121. By providing the first groove 4111 and the second groove 5121, it is convenient to position, install and fix the first inductor 21 and the second inductor 22 during the assembly process, prevent the inductor 2 from shifting when being butt-welded with the connecting member 4, the first conductive member 51, and the second conductive member 52, and ensure stability during the butt-welding process.

[0074] For example, see Figure 7 The first welding portion 221 and the second welding portion 222 are both hook structures, which can be hung in the first groove 4111 and the second groove 5121 to improve the stability during the butt welding process.

[0075] In some embodiments, see Figure 1 , Figure 2 and Figure 8 The motor end cover also includes a filter assembly 6. A first slot 13 is provided on the end cover body 1. The filter assembly 6 is clamped in the first slot 13. Figure 4-Figure 6 The two conductive members 5 are also provided with power supply terminals 513 , which extend into the first card slot 13 , and the filter assembly is electrically connected to the power supply terminal 513 .

[0076] That is to say, the filter assembly 6 can be clamped in the first clamping slot 13 on the end cover body 1 in a clamping manner, thereby improving the assembly efficiency of the filter assembly 6. Since the power supply terminal 513 extends into the first clamping slot 13, when the filter assembly 6 is clamped in the first clamping slot 13, the filter assembly 6 can be electrically connected to the power supply terminal 513 on the first conductive member 51 and the second conductive member 52, and then the filter assembly 6 is powered by the first conductive member 51 and the second conductive member 52.

[0077] In some embodiments, see Fig.10 The filter assembly 6 includes a circuit board 62 and a filter chip 61, and the filter chip 61 is integrated in the circuit board 62. The circuit board 62 is provided with a first power connection terminal 621 and a second power connection terminal 622, and the first power connection terminal 621 and the second power connection terminal 622 are electrically connected to the power supply terminals 513 on the first conductive member 51 and the second conductive member 52 respectively.

[0078] In the related art, pin-type electronic components are usually used to suppress EMC (Electro Magnetic Compatibility), and manual soldering is required during the assembly process, which reduces the assembly efficiency. The filter assembly 6 used in the embodiment of the present application includes a circuit board 62 and a filter chip 61 integrated on the circuit board 62, and a first power connection terminal 621 and a second power connection terminal 622 are provided on the circuit board 62. When the filter assembly 6 is clamped in the first card slot 13, the first power connection terminal 621 and the second power connection terminal 622 are respectively in contact with the power supply terminals 513 on the first conductive member 51 and the second conductive member 52, so that electrical connection can be achieved without manual soldering, thereby improving the assembly efficiency.

[0079] For example, see Fig.10 The filter assembly 6 includes a circuit board 62 and a filter chip 61 integrated on the circuit board 62. The filter chip can be a surface mount EMC component with a small overall size and convenient assembly. In addition, other chips, such as surface mount signal components, can also be integrated on the circuit board 62.

[0080] In some embodiments, see Figure 1 , Figure 2 and Figure 8 The motor end cover also includes a grounding component 7. A second slot 14 is provided on the top of the end cover body 1. The grounding component 7 is clamped in the second slot 14. Fig.10 A grounding terminal 623 is provided on the circuit board 62, one end of the grounding component 7 is configured to be electrically connected to the grounding terminal 623, and the other end is configured to be grounded. The grounding component 7 can ensure the stable operation of the filter component 6. In the embodiment of the present application, the grounding component 7 is also connected to the end cover body 1 in the form of a snap connection, thereby improving the assembly efficiency and facilitating the realization of automated installation.

[0081] In some embodiments, see Fig. 9 The grounding assembly 7 includes a plug-in portion 71, a bending portion 72 and a grounding portion 73 connected in sequence, and the plug-in portion 71 and the grounding portion 73 are arranged opposite to each other. A avoidance groove 17 is also arranged on the top of the end cover body 1. Among them, the plug-in portion 71 is plugged into the second card slot 14 and contacts the grounding end 623, the bending portion 72 is located in the avoidance groove 17, and the grounding portion 73 is attached to the side of the end cover body 1, and the grounding portion 73 is configured to be grounded.

[0082] For example, see Figure 8 and Fig. 9 The second card slot 14 is adjacent to the first card slot 13, and a connecting slot 15 is provided between the second card slot 14 and the first card slot 13. The grounding component 7 can be a "U"-shaped structure. The plug-in portion 71 and the grounding portion 73 are connected by a bending portion 72. The plug-in portion 71 can be plugged into the second card slot 14. A contact is provided thereon, which protrudes toward the direction of the first card slot 13 and contacts the grounding terminal 623 on the circuit board 62 to achieve electrical connection with the grounding terminal 623. The grounding portion 73 is located outside the second card slot 14 to facilitate grounding. In order to facilitate the connection between the grounding component 7 and the second card slot 14, the plug-in portion 71 can be set as a "Christmas tree" structure, that is, the plug-in portion 71 includes a plurality of sawtooth structures, and the width of each sawtooth structure decreases successively along the direction close to the end, so as to facilitate the insertion of the plug-in portion 71 into the second card slot 14 and improve the stability of the connection.

[0083] In some embodiments, see Figure 2 The motor end cover also includes a damping member 8, which is attached to the bearing portion 42 and disposed between the bearing portion 42 and the inner wall of the cavity structure 11. Since the bearing portion 42 in the embodiment of the present application is a spring arm structure, vibration will be generated during the operation of the motor, and the damping member can be provided to achieve an anti-vibration effect.
