[0036] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model.

Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

[0037] Reference below Figure 1-Figure 9 A motor 100 according to an embodiment of the present invention is described.
[0038] like Figure 1-Figure 9 As shown, the motor 100 according to the embodiment of the present utility model includes: a motor body 10 , a terminal socket 11 and a connector 14 .
[0039] The motor body 10 is provided with a motor copper busbar 12, the terminal block 11 is installed on the motor body 10 and is provided with at least one slide groove 111, the bottom of the slide groove 111 is provided with an opening 112, the first end 141 of the connecting member 14 is located in the slide groove 111, and the cross-sectional area of the first end 141 is larger than the cross-sectional area of the opening 112, the second end 142 of the connecting member 14 is passed through the opening 112 and is suitable for passing through the motor copper busbar 12, wherein the slide groove 111 and the opening 112 both extend along the first direction, and the connecting member 14 is suitable for moving along the first direction in the slide groove 111.
[0040] Therefore, after the first end 141 of the connecting member 14 is set in the slide groove 111, the connecting member 14 can slide along the first direction in the slide groove 111. In this way, when the motor copper bus 12 is installed after the connecting member 14 is installed on the terminal holder 11, the connecting member 14 can adjust its own position to avoid the problem that the motor copper bus 12 cannot be accurately fixed to the terminal holder 11 due to dimensional tolerance.
[0041] For example, when the terminal socket 11 is set on the motor body 10, the terminal socket 11 can be integrated on the stator assembly 16 to reduce the difficulty of layout, and the bottom of the slide groove 111 set on the terminal socket 11 is provided with an opening 112, and at the same time, the cross-sectional area of the first end 141 of the connecting member 14 is larger than the cross-sectional area of the opening 112, so that after the connecting member 14 is set in the slide groove 111, the opening 112 can limit the first end 141, thereby preventing the connecting member 14 from being separated from the slide groove 111, and the motor copper busbar 12 will be opposite to the terminal socket 11 when it is set on the motor body 10. At this time, the second end 142 of the connecting member 14 is penetrated through the motor copper busbar 12.
[0042] The slide groove 111 may be a waist-shaped groove or a strip-shaped groove, which is not limited here.
[0043] Since the connector 14 can slide in the first direction in the slide slot 111 , it is convenient to adjust the position of the connector 14 to adapt to the dimensional tolerance of the motor copper busbar 12 , thereby enabling the motor copper busbar 12 to be accurately fixed to the wiring seat 11 .
[0044] According to the motor 100 of the embodiment of the utility model, the connector 14 can move in a first direction when it is arranged in the slide groove 111 of the terminal block 11. In this way, when the motor copper busbar 12 has a dimensional tolerance, the position of the connector 14 can be adjusted by sliding the connector 14 so that the connector 14 can be more accurately inserted into the motor copper busbar 12, thereby making it easier to fix the motor copper busbar 12 to the terminal block 11.
[0045] In some embodiments, Figure 1-Figure 5 As shown, the motor 100 further includes: an electric control unit, which is provided with an electric control copper busbar 13 , the motor copper busbar 12 is provided with a clearance opening 121 , and the second end 142 of the connector 14 is passed through the clearance opening 121 to be fixedly matched with the electric control copper busbar 13 .
[0046] Thus, the connecting member 14 can move in the first direction in the slide groove 111, so that the connecting member 14 can adjust its own position when it is inserted into the avoidance opening 121 of the motor copper busbar 12, thereby making it easier to fix the second end 142 of the connecting member 14 with the electric control copper busbar 13, and thus avoiding the unstable connection effect caused by the dimensional tolerance and assembly tolerance of the motor copper busbar 12.
[0047] In some embodiments, Figure 1-Figure 4 As shown, the avoidance opening 121 and the opening 112 are designed to follow the shape.
[0048] Therefore, the avoidance opening 121 and the opening 112 are designed to conform to the shape so that the connector 14 can also slide relative to the motor copper busbar 12 when sliding in the first direction. In this way, when the connector 14 is fixedly matched with the electric control copper busbar 13, the connector 14 can slide to avoid the problem of inability to accurately fix the electric control copper busbar 13 due to the dimensional tolerance.
[0049] For example, the motor copper bar 12 and the electric control copper bar 13 may both be hard copper bars to reduce the cost of the motor 100 , but the connection between the two hard copper bars may cause the problem of being unable to be assembled due to dimensional tolerance.
[0050] Therefore, in this embodiment, the connecting member 14 can slide in the first direction in the slide groove 111, so that when the connecting member 14 is inserted into the motor copper busbar 12 and then fixedly matched with the electric control copper busbar 13, the relative position of the connecting member 14 and the motor copper busbar 12 can be adjusted by the movement of the connecting member 14 in the first direction to adapt to the dimensional tolerance of the electric control copper busbar 13, thereby avoiding the problem of insufficient connection accuracy caused by the dimensional tolerance of the electric control copper busbar 13.
[0051] In some embodiments, the motor copper bar 12 and the electric control copper bar 13 are both hard copper bars.
[0052] Therefore, the use of hard copper bars for both the motor copper bar 12 and the electric control copper bar 13 can effectively reduce the cost of the motor 100, thereby achieving better economic benefits for the motor 100.
[0053] In some embodiments, Figure 1-Figure 5 As shown, the electric control copper busbar 13 is provided with a card interface 131 , and the card interface 131 is suitable for card-engaging with the second end 142 of the connector 14 .
[0054] For example, the lower end of the card interface 131 is open, so that the electric control copper busbar 13 can be more quickly engaged with the second end 142, thereby improving the assembly efficiency of the motor 100. At the same time, when the electric control copper busbar 13 is connected to the connecting member 14, the connecting member 14 can play a certain guiding role on the electric control copper busbar 13, so that the connecting member 14 can be connected to the electric control copper busbar 13 more easily.
[0055] In other embodiments, after the connecting member 14 is arranged in the slide groove 111, it can also slide along the second direction, and the second direction intersects with the first direction. In this embodiment, the second direction is perpendicular to the first direction. In this way, the adjustment range of the relative position of the connecting member 14 and the motor copper busbar 12 can be increased, thereby making it easier for the connecting member 14 to be engaged with the card interface 131 of the electric control copper busbar 13.
[0056] In some embodiments, Figure 1-Figure 7 As shown, the motor 100 also includes: a nut 15, the connecting member 14 is constructed as a stud, the nut 15 is located on the side of the electric control copper busbar 13 away from the motor copper busbar 12, and the nut 15 is suitable for threaded cooperation with the second end 142 of the stud to make the electric control copper busbar 13 abut against the motor copper busbar 12.
[0057] Therefore, the connecting piece 14 constructed as a stud is matched with the electric control copper busbar 13 and then fastened by the nut 15. In this way, under the action of the nut 15, the electric control copper busbar 13 and the motor copper busbar 12 can be offset against each other to achieve conduction, and the electric control copper busbar 13 and the motor copper busbar 12 fastened by the nut 15 are not easy to separate, so as to enhance the connection stability.
[0058] In some embodiments, Figure 1-Figure 5As shown, the wiring seat 11 is constructed as an arc-shaped structure, and a plurality of slide grooves 111 are provided. The plurality of slide grooves 111 are distributed and spaced apart along the circumference of the arc-shaped structure.
[0059] Therefore, the terminal socket 11 constructed as an arc structure is easier to cooperate with the motor 100, and a plurality of slide grooves 111 are arranged on the terminal socket 11 so that a plurality of connectors 14 can be arranged on the terminal socket 11. In this way, when the motor copper busbar 12 is fixed respectively by a plurality of connectors 14, interference of the connectors 14 can be avoided, and it is helpful to reduce the difficulty of setting the slide grooves.
[0060] For example, the motor 100 is a three-phase motor, and three slide grooves 111 are provided on the terminal block 11. In this way, after three connecting pieces 14 are respectively arranged in the three slide grooves 111, they can correspond to three motor copper bars 12 and three electric control copper bars 13, thereby ensuring that the three-phase motor can be used normally. At the same time, the three connecting pieces 14 are all constructed as studs, so that the electric control copper bar 13 and the motor copper bar 12 fastened by the nut 15 can be better connected.
[0061] The terminal block 11 is an integrated terminal block 11 , so that the terminal block 11 is more convenient to cooperate with the motor copper busbar 12 , and the motor copper busbar 12 can also be better fixed on the terminal block 11 .
[0062] In some embodiments, Figure 1-Figure 9 As shown, the terminal block 11 is provided with a guide structure 113 , and the guide structure 113 is matched with the motor copper busbar 12 for guidance.
[0063] Therefore, the guide structure 113 can play a guiding role when the motor copper busbar 12 is assembled on the terminal holder 11, thereby making it easier to connect the motor copper busbar 12 to the terminal holder 11. At the same time, the guide structure 113 can fix the motor copper busbar 12 after assembly.
[0064] For example, the guide structure 113 can be constructed as a guide column or a guide groove. Preferably, in the present embodiment, the guide structure 113 is constructed as a guide column, which can make it more convenient to install the motor copper busbar 12 on the terminal block 11.
[0065] In some embodiments, Figure 1-Figure 9 As shown, the guide structure 113 is located outside the slide groove 111 .
[0066] Therefore, the guide structure 113 will not affect the connecting member 14 in the slide groove 111 , so that the connecting member 14 will not interfere with the guide structure 113 when the slide groove 111 is able to slide.
[0067] According to the motor 100 of the embodiment of the utility model, the motor copper bar 12, the connecting piece 14 and the terminal block 11 are integrated on the stator assembly 16 of the motor 100. Figure 3 The rectangular rail shown in the figure will Figure 6 After the connecting member 14 shown is installed into the rectangular slide rail, the connecting member 14 can be Figure 1 The first direction indicated by the arrow is sliding left and right, and the motor copper bar 12 also exists Figure 4 The avoidance opening 121 shown can slide left and right with the connector 14 without interference. After the stator assembly 16 of the motor 100 is heat-fitted into the motor body 10, the electric control copper bar 13 is assembled from top to bottom. Figure 5 The card interface 131 shown can be card-connected with the connector 14 during the assembly process.
[0068] For example, the motor copper busbar 12 and the electric control copper busbar 13 are both hard copper busbars. During the assembly process, due to the manufacturing tolerances of parts and the process tolerances of the production line, if the motor copper busbar 12 and the electric control copper busbar 13 cannot be installed, the installation position can be adjusted through the connector 14 on the terminal block 11 and the card interface 131 on the electric control copper busbar 13 to achieve successful connection between the motor copper busbar 12 and the electric control copper busbar 13.
[0069] Therefore, the stator assembly 16 of the motor 100 proposed by the utility model integrates the function of the terminal block 11, and there is no need to produce more expensive soft copper bars, which saves material costs for the development of the motor 100. At the same time, the structure supports the adjustment of the position of the connecting piece 14 of the motor copper bar 12 and the electric control copper bar 13 up and down (second direction) and left and right (first direction), which in disguise reduces the dimensional accuracy requirements of the production line assembly process, thereby also reducing the process cost of the production line. In summary, the structure is very economical.
[0070] The utility model also provides a vehicle 1000 .

[0072] According to the vehicle 1000 of the embodiment of the utility model, in the motor 100 thereon, the connector 14 can move in a first direction when it is arranged in the slide groove 111 of the terminal block 11. In this way, when the motor copper busbar 12 has a dimensional tolerance, the position of the connector 14 can be adjusted by sliding the connector 14 so that the connector 14 can be more accurately inserted into the motor copper busbar 12, thereby making it easier to fix the motor copper busbar 12 to the terminal block 11.
