[0026] The embodiment of the present application provides a motor controller, as Figures 1 to 2 shown, the motor controller includes:

[0027] A controller housing 100, on one side of which there is a wire splitter socket 110;

[0028] A filter 200, which is arranged in the controller housing 100 and includes a housing component 210 and a connecting copper bar 220, and the connecting copper bar 220 is arranged on the housing component 210;

[0029] The split plug 300 is plugged into the split socket 110 and includes a wire harness 310. The wire harness 310 is connected to the connecting copper bar 220, and the connection point between the wire harness 310 and the connecting copper bar 220 is higher than the split socket 110.

[0030] Wherein, a guiding structure is provided on one side of the housing part 210 close to the split socket 110, and the guiding structure guides the wire harness 310 to the connection point between the wire harness 310 and the connecting copper bar 220.

[0031] As Figure 1 shown, in this embodiment, by way of example, the controller housing 100 serves as an external protection device, which can be set as a cast aluminum part. The controller housing 100 can be cast separately, that is, the motor controller and the motor are separately arranged; it can also be integrally cast with the motor housing, that is, the motor controller and the motor are integrated. Taking the separately cast controller housing 100 as an example in this embodiment, the controller housing 100 in this embodiment can be set as a structure similar to a cuboid shape, and its top can be open to facilitate arranging structures such as the filter 200 in the controller housing 100. The filter 200 can be detachably connected to the controller housing 100 through components such as bolts. The top opening of the controller housing 100 can be sealed by an upper cover, and the upper cover is detachably arranged with the controller housing 100. Of course, in some embodiments, the bottom of the controller housing 100 can also be set as a similar structure and sealed by a lower cover.

[0032] As Figure 1 and Figure 2 shown, the housing part 210 of the filter 200 serves as its support structure, which can specifically be set as an injection molded part, and the connecting copper bar 220 can be integrally arranged with the housing part 210 during the injection molding process of the housing part 210. At the same time, at least part of the connecting copper bar 220 is exposed on the surface of the housing part 210 to facilitate connection with the wire harness 310 of the split plug 300. When connecting, the split plug 300 is plugged into the split socket 110, and the split plug 300 can also be locked and fixed through components such as bolts. At this time, the bolt passes through the split plug 300 and is screwed into the split socket 110. The wire harness 310 can pass through the split socket 110 and extend into the controller housing 100 to be connected to the connecting copper bar 220, and the wire harness 310 can abut against the part of the connecting copper bar 220 exposed on the surface of the housing part 210. Taking the horizontal plane as a reference, the connection point between the wire harness 310 and the connecting copper bar 220 is at a higher position compared to the split socket 110.

[0033] As Figure 1 and Figure 2As shown, based on this, a guiding structure for guiding the wire harness 310 is provided on the housing part 210. The guiding structure is arranged on the side of the housing part 210 close to the branch socket 110. When the wire harness 310 passes through the branch socket 110 and enters the controller housing 100, the wire harness 310 abuts against the side of the housing part 210 close to the branch socket 110. At this time, due to the existence of the guiding structure, the wire harness 310 can extend towards the connection point between the wire harness 310 and the connecting copper bar 220 under the action of the driving force, that is, it moves upward and approaches the connection point between the wire harness 310 and the connecting copper bar 220 during the insertion process. And through the guidance of the guiding structure, the wire harness 310 can be conveniently connected to the connecting copper bar 220 without manual guidance.

[0034] It can be understood that in this application, by arranging the guiding structure on the side of the housing part 210 of the filter 200 close to the branch socket 110, when the branch plug 300 is connected to the branch socket 110, the guiding structure can guide the wire harness 310 of the branch plug 300, so that the wire harness 310 can extend towards the connection point between it and the connecting copper bar 220 without manual guidance. Furthermore, this application can effectively improve the problem that it is difficult to guide and inconvenient to wire the wire harness 310 of the branch socket 110 when connecting to the filter 200.

[0035] Specifically, there are two sets of branch sockets 110 and branch plugs 300, and the two sets of branch sockets 110 and branch plugs 300 are arranged adjacent to each other. The guiding structure includes a first guiding structure and a second guiding structure corresponding one-to-one to the two sets of branch sockets 110 and branch plugs 300.

[0036] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the branch sockets 110 and the branch plugs 300 are arranged in groups in one-to-one correspondence. And the branch sockets 110 and the branch plugs 300 can be provided with two sets according to actual needs to meet different functional requirements respectively. The two branch sockets 110 can be arranged on the same side of the controller housing 100 and adjacent to each other. In this embodiment, the two branch sockets 110 are specifically arranged on one side in the length direction of the controller housing 100. The positions of the two branch sockets 110 can be arranged according to actual needs, and they can be arranged at different height positions. Correspondingly, the two branch plugs 300 are also adjacent. On the side of the housing part 210 close to the two branch sockets 110, two guiding structures, namely the first guiding structure and the second guiding structure, are correspondingly arranged to guide the wire harnesses 310 of the two branch plugs 300 respectively.

[0037] It can be understood that in this embodiment, by providing a first guiding structure and a second guiding structure that correspond one-to-one to the two-component wire socket 110 and the wire splitter plug 300, the wire harnesses 310 of the two wire splitter plugs 300 can be effectively guided.

[0038] More specifically, the first guiding structure includes a guiding side plate 400. The guiding side plate 400 is connected to the housing member 210. The guiding side plate 400 has at least one inclined guiding plane 410, and the guiding plane 410 guides the wire harness 310.

[0039] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the first guiding structure can be provided near one side in the width direction of the controller housing 100, and it specifically includes a guiding side plate 400. The guiding side plate 400 can be set as a rectangular plate, and it can be integrally formed with the housing member 210. The guiding plate can be inclined relative to the horizontal plane so that one side of its top forms an inclined guiding plane 410. The lower end of the guiding plate is close to the wire socket 110 and extends to a position lower than the wire socket 110. When the wire splitter plug 300 corresponding to the first guiding structure is plugged into the corresponding wire socket 110, the wire harness 310 of the wire splitter plug 300 can contact the guiding plane 410 under the action of a driving force, and the guiding plane 410 can guide it upward to its connection point with the connecting copper bar 220.

[0040] It can be understood that in this embodiment, the wire harness 310 is guided by the inclined guiding plane 410 of the guiding side plate 400, realizing a reasonable setting of the first guiding structure, and further enabling it to play a role in guiding the wire harness 310.

[0041] More specifically, the filter 200 further includes a magnetic ring. The second guiding structure includes a guiding housing 500 provided outside the magnetic ring. The guiding housing 500 has at least one guiding arc surface 510, and the guiding arc surface 510 guides the wire harness 310.

[0042] As Figure 1 and Figure 2As shown, in this embodiment, by way of example, the second guiding structure may be provided in the middle of the controller housing 100 in the width direction, and specifically may include a guiding housing 500. The guiding housing 500 may be specifically provided as a part of the housing member 210 and is used for arranging the magnetic ring of the filter 200; its shape may be adapted to the shape of the magnetic ring, that is, specifically provided as a flat annular structure. Both sides in the length direction of the guiding housing 500 may be provided as semi-circular arc surfaces, and both sides in the width direction may be provided as flat surfaces; and the guiding arc surface 510 is one of the semi-circular arc surfaces of the guiding housing 500 close to the wire splitter socket 110. When the wire splitter plug 300 corresponding to the second guiding structure is plugged into the corresponding wire splitter socket 110, the wire harness 310 of the wire splitter plug 300 may contact the guiding arc surface 510 under the action of a driving force, specifically may contact the top of the guiding arc surface 510, and the top of the guiding arc surface 510 may guide it upward to its connection with the connecting copper bar 220.

[0043] It can be understood that in this embodiment, the top of the guiding arc surface 510 of the guiding housing 500 is used to guide the wire harness 310, realizing the reasonable setting of the second guiding structure, and further enabling it to play the role of guiding the wire harness 310.

[0044] More specifically, the second guiding structure further includes guiding helical teeth 600. The guiding helical teeth 600 are provided at the bottom of the guiding housing 500, and the guiding helical teeth 600 guide the wire harness 310 to the top of the guiding arc surface 510.

[0045] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the guiding helical teeth 600 may be integrally formed with the guiding housing 500, may be provided in a shape similar to a triangle, and may be provided at the bottom of the guiding housing 500; the width of the guiding helical teeth 600 increases successively from top to bottom. The guiding helical teeth 600 may be provided in a vertical plane, and along the axial direction of the guiding housing 500, the guiding helical teeth 600 may be spaced apart and provided as several. When the wire splitter plug 300 corresponding to the second guiding structure is plugged into the corresponding wire splitter socket 110, if the wire harness 310 of the wire splitter plug 300 can contact the bottom of the guiding arc surface 510 under the action of a driving force, it may abut against the guiding helical teeth 600, and the guiding helical teeth 600 may redirect it to the top of the guiding arc surface 510 so that the guiding arc surface 510 can further guide the wire harness 310.

[0046] It can be understood that in this embodiment, by providing the guiding helical teeth 600, when the wire harness 310 contacts the bottom of the guiding arc surface 510, the wire harness 310 can be guided by it to contact the top of the guiding arc surface 510, so that the top of the guiding arc surface 510 can further guide it to the connection part with the connecting copper row 220. At the same time, the guiding helical teeth 600 can also play a role similar to that of a reinforcing rib to improve the structural strength of the guiding housing 500.

[0047] Specifically, the connection part between the wire harness 310 and the connecting copper row 220 is arranged at the top of the housing part 210, and the connecting copper row 220 is at least horizontally arranged at the connection part between the wire harness 310 and the connecting copper row 220.

[0048] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the part of the connecting copper row 220 exposed outside the housing part 210 at least includes the top of the housing part 210, and this part is horizontally arranged. When the wire harness 310 is guided by the guiding structure, the wire harness 310 extends upward to the top of the housing part 210 and abuts against the exposed part of the connecting copper row 220. Since this part is horizontally arranged, the connection is more convenient.

[0049] It can be understood that in this embodiment, by reasonably setting the position of the connection part between the wire harness 310 and the connecting copper row 220, it is convenient for the wire harness 310 to be connected to the connecting copper row 220 after being guided by the guiding structure.

[0050] More specifically, the wire harness 310 includes a negative wire harness 311, the connecting copper row 220 includes a negative copper row 221, and the negative wire harness 311 and the negative copper row 221 are connected by a first screwing member 700, and the first screwing member 700 is arranged on the housing part 210.

[0051] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the wire harness 310 may include a negative wire harness 311; correspondingly, the connecting copper row 220 may include a negative copper row 221, and the negative wire harness 311 and the negative copper row 221 are directly connected. When the branch plug 300 is inserted into the branch socket 110, the guiding structure can simultaneously guide the negative wire harness 311 and guide it to the connection part with the negative copper row 221. And the negative wire harness 311 and the negative copper row can be locked and fixed by the first screwing member 700. The first screwing member 700 can pass through the negative wire harness 311 and the negative copper row 221 from top to bottom and be screwed on the housing part 210.

[0052] It can be understood that in this embodiment, the negative copper busbar 221 and the negative wire harness 311 after being guided by the guiding structure are locked and fixed on the housing member 210 through the first screwing member 700, which can conveniently and quickly realize the connection between the negative copper busbar 221 and the negative wire harness 311.

[0053] Specifically, the wire harness 310 further includes a positive wire harness 312, the connecting copper busbar 220 further includes a positive copper busbar 222, and the motor controller further includes a fuse 800. Both ends of the fuse 800 are respectively connected to the positive wire harness 312 and the positive copper busbar 222.

[0054] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the wire harness 310 may further include a positive wire harness 312. Correspondingly, the connecting copper busbar 220 may further include a positive copper busbar 222. The positive wire harness 312 may be electrically connected to the positive copper busbar 222 through the fuse 800 to facilitate the formation of a current loop. Both ends of the fuse 800 are respectively connected to the positive wire harness 312 and the positive copper busbar 222, which is used to improve the circuit safety. When the splice plug 300 is plugged into the splice socket 110, the guiding structure may also guide the positive wire harness 312 at the same time. Different from the negative wire harness 311 and the negative copper busbar 221, when the guiding structure guides the positive wire harness 312, the positive wire harness 312 is guided to the connection point with the fuse 800.

[0055] It can be understood that in this embodiment, by providing the fuse 800 and reasonably setting the installation position of the fuse 800, the safety of the circuit can be improved.

[0056] More specifically, the connection points of the fuse 800 with the positive wire harness 312 and the positive copper busbar 222 are both provided at the top of the housing member 210.

[0057] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, since when the guiding structure guides the positive wire harness 312 and the negative wire harness 311, it makes both the positive wire harness 312 and the negative wire harness 311 extend upward without distinction. Based on this, the fuse 800 can also be provided at the top of the housing member 210. During assembly, the fuse 800 can be first connected to the positive copper busbar 222; and then, when the positive wire harness 312 extends to the top of the housing member 210 under the guiding action of the guiding structure, the fuse 800 can be connected to the positive wire harness 312.

[0058] It can be understood that in this embodiment, by providing the fuse 800 at the top of the housing member 210, it is convenient to connect the fuse 800 with the positive wire harness 312 after being guided by the guiding structure.

[0059] More specifically, the fuse 800 is horizontally arranged, and both ends of the fuse 800 are connected to the positive electrode wire harness 312 and the positive electrode copper row 222 through the second screwing member 900, and the second screwing member 900 is arranged on the housing member 210.

[0060] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the fuse 800 can be horizontally arranged on the top of the housing member 210, and both ends thereof can be locked and fixed to the positive electrode wire harness 312 and the positive electrode copper row 222 through the second screwing member 900 respectively. The second screwing member 900 can pass through the end of the fuse 800 and the positive electrode wire harness 312 or the positive electrode copper row 222 from top to bottom, and is screwed onto the housing member 210.

[0061] It can be understood that in this embodiment, by horizontally arranging the fuse 800 and locking and fixing it to the positive electrode wire harness 312 and the positive electrode copper row 222 through the second screwing member, the fuse 800 can be more conveniently connected to the positive electrode wire harness 312 and the positive electrode copper row 222.

[0062] The implementation principle of a motor controller provided by an embodiment of the present application is as follows:

[0063] During assembly, the two branch plugs 300 are respectively plugged into the two branch sockets 110. When plugging, the wire harness 310 of the branch plug 300 corresponding to the first guiding structure can contact the guiding plane 410 under the action of a driving force, and the guiding plane 410 can guide it upward to its connection point with the connection copper row 220. The wire harness 310 of the branch plug 300 corresponding to the second guiding structure can contact the top of the guiding arc surface 510 under the action of a driving force, and the top of the guiding arc surface 510 can guide it upward to its connection point with the connection copper row 220. At the same time, even if the wire harness 310 contacts the bottom of the guiding arc surface 510, it can abut against the guiding helical teeth 600, and the guiding helical teeth 600 can redirect it to the top of the guiding arc surface 510 so that the guiding arc surface 510 can further guide the wire harness 310. When the wire harness 310 is connected to the connection copper row 220, the negative electrode wire harness 311 and the negative electrode copper row 221 can be directly locked and fixed to the housing member 210 through the first screwing member 700, and at the same time, both ends of the fuse 800 can be locked and fixed to the positive electrode wire harness 312 and the positive electrode copper row 222 through the second screwing member 900 on the housing member 210.

[0064] In the present application, a guiding structure is provided on the side of the housing part 210 of the filter 200 close to the distribution socket 110. When the distribution plug 300 is connected to the distribution socket 110, the guiding structure can guide the wire harness 310 of the distribution plug 300, so that the wire harness 310 can extend to its connection point with the connection bus bar 220 without manual guidance. Furthermore, the present application can effectively improve the problem that it is difficult to guide and inconvenient to wire the wire harness 310 of the distribution socket 110 when it is connected to the filter 200.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
