DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

In the first direction, the direction close to the circuit board 200 is the upper direction, and the direction close to the stator 100 is the lower direction. "Up" and "down" correspond to Figure 1 , Figures 5 to 7 The upper and lower directions in the direction of the drawing. In the present disclosure, the directional words "inside" and "outside" refer to the "inside" and "outside" relative to the own contour of the corresponding component. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have sequentiality and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0038] According to a first aspect of the present disclosure, there is provided a motor, Figures 1 to 9 As shown in the figure, the motor includes a stator 100 and a circuit board 200, and the motor also includes a connector 300. The stator 100 is provided with a mounting portion, and the connector 300 has a first end and a second end opposite to each other, the first end is provided with a clamping portion, and the second end is electrically connected to the circuit board 200. The connector 300 is limited to the mounting portion by the clamping portion.

[0039] Through the above technical solution, in the motor provided by the present disclosure, the stator 100 is provided with a mounting portion, and the connector 300 is limited to the mounting portion by the clamping portion, so that the connector 300 can be limited to the stator 100 to achieve a stable connection between the connector 300 and the stator 100. In addition, the second end of the connector 300 is electrically connected to the circuit board 200, so that the connector 300 can achieve an electrical connection between the circuit board 200 and the stator 100 and ensure the reliability of the electrical connection between the circuit board 200 and the stator 100.

[0040] In the motor provided by the present disclosure, the connector 300 and the stator 100 may be connected in any suitable manner. Figure 6 and Figure 7 As shown in , the connector 300 can be installed on the stator 100 through a clamping structure, and the clamping structure can include a clamping slot 120 and a clamping arm 310. One of the clamping portion and the mounting portion can be configured as the clamping arm 310, and the other can be configured as the clamping slot 120. The clamping arm 310 can extend into the clamping slot 120 and be limited in the first direction to the clamping slot 120. In this way, after the connector 300 and the stator 100 are installed, the clamping arm 310 can be limited in the clamping slot 120 along the first direction, that is, the connector 300 can be limited in the stator 100 along the first direction to prevent the connector 300 from escaping from the stator 100 along the first direction, thereby ensuring the connection reliability between the connector 300 and the stator 100.

[0041] In the motor provided in the present disclosure, as an exemplary embodiment, reference is made to Figures 3 to 7As shown in , the mounting portion can be configured as a slot 120, and the clamping arm 310 can be provided on the connector 300. The slot 120 can include a first through slot 121 and a second through slot 122 that are connected. The first through slot 121 and the second through slot 122 can be arranged up and down in the first direction, and a stop surface 123 can be formed between the first through slot 121 and the second through slot 122. The clamping arm 310 can be clamped in the second through slot 122 and used to abut against the stop surface 123. In this way, when the connector 300 is installed in the stator 100, the clamping arm 310 will pass through the first through slot 121 and the second through slot 122 in sequence. After the connector 300 and the stator 100 are installed in place, the clamping arm 310 can be clamped in the second through slot 122 and abut against the stop surface 123. Therefore, the stop surface 123 can prevent the clamping arm 310 from sliding out of the clamping slot 120 along the first direction. That is, the cooperation between the clamping arm 310 and the stop surface 123 can prevent the connecting member 300 from sliding out of the stator 100 along the first direction.

[0042] In the motor provided in the present disclosure, the clamping arm 310 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figures 6 to 8 As shown in , the connector 300 may include a main body 320, the clamping arm 310 may be connected to the main body 320, and a first notch 330 may be formed between the main body 320 and the clamping arm 310 to provide a space for the clamping arm 310 to move toward the main body 320. In this way, when the clamping arm 310 abuts against the slot wall of the first through slot 121, the clamping arm 310 will move toward the main body 320 so that the first notch 330 will be in a squeezed state. Therefore, by providing the first notch 330, it is easy to insert the clamping arm 310 into the slot 120; when the clamping arm 310 is located in the second through slot 122, the clamping arm 310 will move away from the main body 320 under its own elastic action so that the first notch 330 returns to its original shape. At this time, the clamping arm 310 can be located at the stop surface 123 at the upper limit in the first direction.

[0043] As yet another exemplary embodiment, refer to Fig. 9As shown in the figure, the connecting member 300 may include a main body 320 and is provided with a connecting groove 323. The connecting groove 323 may be recessed inward from the end of the main body 320 along the second direction. The clamping arm 310 may be connected to the groove wall of the connecting groove 323 and extend along the first direction. The clamping arm 310 may be elastic and have a first state and a second state. In the first state, the groove wall of the first through groove 121 presses the clamping arm 310 into the connecting groove 323; in the second state, the clamping arm 310 may pop out from the connecting groove 323 and be clamped in the second through groove 122 and is used to abut against the stop surface 123. In this way, in the process of installing the connecting piece 300 on the stator 100, the clamping arm 310 will pass through the first through slot 121 and the second through slot 122 successively. When the clamping arm 310 is located in the first through slot 121, the clamping arm 310 is in the first state to ensure that the clamping arm 310 can be smoothly inserted into the clamping slot 120. When the clamping arm 310 is located in the second through slot 122, the clamping arm 310 is in the second state to ensure that the clamping arm 310 can abut against the stop surface 123 to prevent the clamping arm 310 from slipping out of the clamping slot 120.

[0044] In which, the clamping arm 310 may include an arm body 311, the arm body 311 may extend obliquely and have a first end and a second end relative to each other in a first direction, the first end may be fixedly connected to the groove wall of the connecting groove 323, and the second end may be provided with a second notch 3111. In the first state, the second end may contact the groove wall of the first through groove 121 and undergo elastic deformation; in the second state, at least part of the second end may protrude from the connecting groove 323. In this way, when the clamping arm 310 is located in the first through groove 121, the clamping arm 310 is in a first state, and the second end of the clamping arm 310 will move toward the second notch 3111 under the pressure of the groove wall of the first through groove 121, so that the second notch 3111 becomes smaller, which is conducive to inserting the clamping arm 310 into the clamping groove 120; when the clamping arm 310 is located in the second through groove 122, the clamping arm 310 is in a second state, and the second end of the clamping arm 310 will restore its original shape and protrude from the connecting groove 323, so as to ensure that the clamping arm 310 can abut against the stop surface 123 to prevent the clamping arm 310 from slipping out of the clamping groove 120.

[0045] In this embodiment, in order to protect the clamping arm 310, refer to Fig. 9In the embodiment, the clamping arm 310 may further include a protective block 312, which may be connected to the arm body 311 and protrude toward the main body 320 along the second direction, so as to abut against the main body 320. It should be noted that "protruding toward the main body 320" means that the protective block 312 is arranged on the side of the arm body 311 facing the main body 320, and when the arm body 311 is squeezed, the protective block 312 is used to abut against the groove wall of the connecting groove 323. In this way, when the arm body 311 moves toward the connecting groove 323 along the second direction, the protective block 312 can abut against the main body 320, so as to prevent the arm body 311 from being broken due to excessive displacement along the second direction.

[0046] In the motor provided in the present disclosure, as an exemplary embodiment, reference is made to Figures 6 to 9 As shown in , the card slot 120 can be constructed in a T-shape and formed with two symmetrically arranged stop surfaces 123, the number of the clamping arms 310 can be two, and the two clamping arms 310 can be symmetrically arranged on both sides of the connecting member 300 along the second direction, and are respectively used to abut against the two stop surfaces 123 in a one-to-one correspondence. Among them, the symmetrical arrangement of the clamping arms 310 and the provision of the two stop surfaces 123 can make the forces on both sides of the connecting member 300 balanced, prevent the connecting member 300 from shifting during the installation of the stator 100, and contribute to the overall structural stability. In other embodiments, the card slot 120 can also be constructed in an L-shape, that is, the second through slot 122 can be provided only on one side, and the number of the clamping arms 310 can be set to one, so that the clamping connection between the card slot 120 and the clamping arms 310 can also be achieved, and the present disclosure does not make specific restrictions on this.

[0047] In the motor provided in the present disclosure, in order to facilitate the installation of the connecting member 300, as an exemplary embodiment, reference is made to Figure 8 and Fig. 9 As shown in , the first end portion may be provided with a guide portion 340 , and the guide portion 340 is used to guide the connector 300 to be inserted into the card slot 120 .

[0048] The cross section of the guide portion 340 in the second direction can be gradually enlarged from the first end portion inwardly along the first direction. That is, the guide portion 340 can be designed as a trapezoidal structure with a size gradually increasing from the first end portion toward the main body portion 320, so that the connector 300 can be easily inserted into the slot 120, and the operation is convenient. Figure 7 As shown in , the first end portion may not be provided with the guide portion 340, which can save the arrangement space of the card slot 120 in the first direction, and the present disclosure does not make any specific restrictions on this.

[0049] In the motor provided by the present disclosure, the electrical connection between the connector 300 and the stator 100 can be achieved in any suitable manner. As an exemplary embodiment, the stator 100 can be wound with a coil 110, the first end can be electrically connected to the coil 110, and the second end can be plugged into the circuit board 200 to be electrically connected to the circuit board 200. In this way, the coil 110 and the circuit board 200 can be electrically connected through the connector 300.

[0050] In the motor provided in the present disclosure, the electrical connection between the connector 300 and the coil 110 can be achieved in any suitable manner. As an exemplary embodiment, refer to Figure 8 and Fig. 9 As shown in , the connector 300 may be provided with a wire insertion slot 360, which may be recessed inward from the first end along the first direction, and the wire insertion slot 360 may be formed with a cutting area and a receiving area along the first direction, the cutting area may be arranged near the notch of the wire insertion slot 360 and used to pierce the insulation layer of the coil 110 located in the wire insertion slot 360, and the receiving area is used to accommodate the coil 110 and be electrically connected to the coil 110. In this way, during the process of installing the connector 300 to the stator 100, the coil 110 will first pass through the cutting area, wherein the cutting area may be set to a blade shape so that the cutting area pierces the insulation layer of the coil 110, so that the conductor inside the coil 110 is exposed. After that, the coil 110 will enter the receiving area, so that the conductor inside the coil 110 can contact the receiving area to achieve electrical connection between the coil 110 and the connector 300.

[0051] In the present disclosure, the clamping arm 310 can be deformed by being squeezed by the groove wall of the first through groove 121, so that the wire insertion groove 360 ​​shrinks in the second direction to pierce the insulation layer of the coil 110 located in the wire insertion groove 360. In this way, when the connector 300 is installed on the installation portion, the wire insertion groove 360 ​​will shrink synchronously so that the cutting area pierces the insulation layer of the coil 110, thereby ensuring the reliability of the electrical connection between the coil 110 and the connector 300.

[0052] In the present disclosure, the wire insertion slot 360 can be constructed in any suitable manner. As an exemplary embodiment, the width of the notch of the wire insertion slot 360 in the second direction can be gradually reduced from the first end along the first direction inward. Among them, the notch width of the wire insertion slot 360 is greater than the diameter of the coil 110, so that it is easy for the coil 110 to enter the wire insertion slot 360. When the coil 110 enters the wire insertion slot 360, the coil 110 will move along the first direction close to the accommodating area. During this process, the cutting area will first contact the insulating layer of the coil 110 and then pierce the insulating layer. In this embodiment, the width of the notch of the wire insertion slot 360 in the second direction can be gradually reduced from the first end along the first direction inward, that is, the wire insertion slot 360 can be constructed in a trumpet shape.

[0053] In another exemplary embodiment, the width of the notch of the cutting zone in the second direction can be gradually reduced from the first end along the first direction inward, that is, the cutting zone can be constructed in a trumpet shape, and the notch of the accommodating zone can be constructed in a circular shape, so as to avoid the contact dead angle, which is conducive to the electrical connection between the accommodating zone and the coil 110. In another exemplary embodiment, the width of the notch of the cutting zone in the second direction can be gradually reduced from the first end along the first direction inward, and then remain unchanged along the first direction inward, that is, the cutting zone can be constructed in a funnel shape, and the notch of the accommodating zone can be constructed in a circular shape. In other embodiments, the plug-in slot 360 can also be constructed in other suitable ways, and the present disclosure does not specifically limit this.

[0054] In the motor provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 8 and Fig. 9 As shown in , the connector 300 may include a main body 320 and a positioning protrusion 350. The positioning protrusion 350 may protrude from the main body 320 along the second direction and is used to abut against the notch of the slot 120. In this way, the positioning protrusion 350 can abut against the top of the slot 120. On this basis, since the clamping arm 310 can be limited to the slot 120 along the first direction, the positioning protrusion 350 cooperates with the clamping arm 310 so that the connector 300 can be stably installed on the stator 100.

[0055] In the motor provided in the present disclosure, in order to facilitate the connection between the circuit board 200 and the connecting member 300, as an exemplary embodiment, reference is made to Figure 8 and Fig. 9 As shown in , the circuit board 200 may be provided with a through hole, and the second end may include a plug-in section 321 and a guide section 322, the cross-section of the plug-in section 321 may be adapted to the shape of the through hole, and the cross-sectional size of the guide section 322 may gradually decrease in a direction away from the plug-in section 321.

[0056] In this way, the guide section 322 has a first end face and a second cross section along the first direction, the size of the first cross section is equal to the size of the plug section 321 (i.e., the size of the through hole), and the size of the second cross section is smaller than the size of the first cross section, that is, the size of the second cross section is smaller than the size of the through hole, and the above arrangement can facilitate the second end to be inserted into the through hole of the circuit board 200. In addition, since the cross section of the plug section 321 is adapted to the shape of the through hole, the shaking between the circuit board 200 and the connector 300 can be avoided, thereby ensuring that a stable electrical connection can be achieved between the circuit board 200 and the connector 300. On this basis, soldering can be performed between the circuit board 200 and the connector 300 to prevent vibration from affecting the connection between the circuit board 200 and the connector 300.

[0057] According to a second aspect of the present disclosure, an electrical device is provided, the electrical device comprising the above-mentioned motor.

[0058] According to a third aspect of the present disclosure, a vehicle is provided, which includes the above-mentioned motor or electrical equipment.

[0059] Before using the motor provided by the present disclosure, the connector 300 needs to be installed in the stator 100. During the installation process, the clamping arm 310 will first abut against the slot wall of the first through slot 121 and undergo elastic deformation, and then the clamping arm 310 will enter the second through slot 122 and restore the elastic deformation. At this time, the clamping arm 310 will abut against the stop surface 123 along the first direction. During the above installation process, the coil 110 will first pass through the cutting area and pierce the insulation layer of the coil 110 by the cutting area, and then enter the accommodating area to achieve electrical connection between the coil 110 and the connector 300. After the connector 300 and the stator 100 are installed, the circuit board 200 can be installed on the second end of the connector 300 to achieve electrical connection between the connector 300 and the circuit board 200.
