[0030] Please refer to Figure 1 , Figure 1It is an exploded structural schematic diagram of an embodiment of the controller provided by the present application. In one aspect of the present application, a controller 100 is provided. The controller 100 includes a circuit board 10, an insulating positioning member 20, and a wire harness 30. Welding holes 11 are provided on the circuit board 10 for the wire harness 30 to pass through and be welded. The insulating positioning member 20 is mounted on the circuit board 10. The insulating positioning member 20 is provided with a guiding hole 21, and the guiding hole 21 is at least partially aligned with the welding hole 11 to ensure that the wire harness 30 passes through the welding hole 11. Along the direction towards the circuit board 10, the aperture of the guiding hole 21 gradually decreases to guide the wire harness 30 to the position of the welding hole 11. The wire harness 30 is inserted into the guiding hole 21 from the direction away from the circuit board 10 and sequentially passes through the guiding hole 21 and the welding hole 11. The controller 100 of the embodiment of the present application can quickly guide the wire harness 30 to the welding hole 11 through the guiding hole 21, improve the assembly efficiency, have accurate positioning, and save working hours.

[0031] Please refer to Figures 2 to 5 , Figure 2 is Figure 1 the assembled structural schematic diagram of the insulating positioning member of Figure 3 is Figure 2 the structural schematic diagram from the bottom view angle of Figure 4 is Figure 2 the structural schematic diagram from the top view angle of Figure 5 is Figure 4 the sectional structural schematic diagram of A-A of Figure 2 As shown, the insulating positioning member 20 can be made of an insulating and high-temperature resistant material, including a main body 22 and a top surface 23 facing the circuit board 10. Combining Figure 3 and Figure 4 it can be seen that the guiding hole 21 is provided on the top surface 23 and penetrates through the main body 22. As Figure 5 shown, the aperture of the guiding hole 21 gradually decreases along the direction towards the circuit board 10, that is, the size of the cross-section of the guiding hole 21 gradually decreases along the direction towards the circuit board 10. When the wire harness 30 is inserted into the guiding hole 21 from the direction away from the circuit board 10, it is guided by the guiding hole 21 to pass through the top surface 23 and then through the welding hole 11. The whole process is fast and has high assembly efficiency, thus saving working hours and reducing costs. Moreover, the wire harness 30 can be quickly guided to the welding hole 11 only through the guiding hole 21, with a simple structure and wide applicability. In a specific embodiment, the shape of the guiding hole 21 can be circular. The circular guiding hole 21 has strong stability and is not easily deformed, which can reduce the resistance when the wire harness 30 passes through and improve the smoothness and assembly rate. Of course, in another specific embodiment, the shape of the guiding hole 21 can also be other polygons to fit the shape of the wire harness 30 and facilitate guiding the wire harness 30 to the position of the welding hole 11.

[0032] Please continue to refer to Figures 6 to 9 , Figure 6 isFigure 1 Schematic diagram of the assembly structure of local components of Figure 7 is Figure 6 Schematic diagram of the enlarged structure of the local part of Figure 8 is Figure 7 Schematic diagram of the structure from a top view of Figure 9 is Figure 7 Schematic diagram of the local structure of . Further, the guiding hole 21 and the welding hole 11 are at least partially aligned. As Figure 8 shown, that is, the aperture of the guiding hole 21 on the top surface 23 is smaller than the aperture of the welding hole 11, so that the inner part of the guiding hole 21 is aligned with the welding hole 11, thereby ensuring that the wire harness 30 accurately passes through the welding hole 11 after passing through the guiding hole 21, improving the positioning accuracy.

[0033] In an embodiment of the present application, as Figure 2 shown, there are multiple guiding holes 21, and the insulating positioning member 20 is provided with a separating portion 24 between every two adjacent guiding holes 21 for improving the insulation safety.

[0034] Specifically, the multiple guiding holes 21 are used to guide multiple wire harnesses 30 to designated positions. The separating portion 24 can be made of an insulating and high-temperature resistant material to play an insulating and isolating role. In a specific embodiment, two guiding holes 21 can be provided to guide the positions of two wire harnesses 30. In another specific embodiment, the number of guiding holes 21 can also be adjusted according to actual needs.

[0035] In an embodiment of the present application, as Figure 1 and Figure 7 shown, the circuit board 10 is further provided with positioning holes 12, and each positioning hole 12 is located between two adjacent welding holes 11. The separating portion 24 is installed in the corresponding positioning hole 12, passes through the positioning hole 12 and extends to be exposed on the side of the circuit board 10 facing away from the insulating positioning member 20. The height of the separating portion 24 exposed outside the circuit board 10 is greater than the length of the wire harness 30 extending out of the welding hole 11, so that the minimum distance between the two wire harnesses 30 is increased, which can play a role in increasing the electrical clearance, thereby improving the insulation safety.

[0036] Specifically, the electrical clearance between two adjacent wire harnesses 30 refers to the minimum distance between two adjacent wire harnesses 30. When the separating portion 24 is not provided or the height of the separating portion 24 exposed outside the circuit board 10 is less than the length of the wire harness 30 extending out of the welding hole 11, the electrical clearance is the straight-line distance between the two wire harnesses 30, as Figure 7As shown, taking the cylindrical wire harness 30 as an example, for a straight line passing through the centers of the cross-sections of two wire harnesses 30, a line segment between two circumferences is taken, and the length L of this line segment is the electrical clearance. After the isolation part 24 is provided and the height of the isolation part 24 exposed outside the circuit board 10 is greater than the length of the wire harness 30 protruding from the welding hole 11, since it is necessary to bypass the isolation part 24 made of an insulating and high-temperature resistant material, the minimum distance between the two wire harnesses 30 increases. The minimum distance is the sum of the lengths L1, L2, and L3 of three line segments. That is to say, the length of the electrical clearance is L1 + L2 + L3, which is greater than L, thereby improving the insulation safety.

[0037] In an embodiment of the present application, please combine Figure 8 and Figure 9 . The positive projection of one edge of the welding hole 11 towards the isolation part 24 is a, and the positive projection of the other edge towards the isolation part 24 is b. Along the positive projection direction towards the isolation part 24, the positive projections a and b of the edges of the welding hole 11 are both located on the isolation part 24. That is to say, along the direction parallel to the isolation part 24, the diameter of the welding hole 11 is smaller than the length of the isolation part 24, so that the minimum distance between the two welding holes 11 increases, that is, the electrical clearance increases, thereby improving the insulation safety.

[0038] Specifically, the electrical clearance here refers to the minimum distance between two adjacent welding holes 11. When the isolation part 24 is not provided, the electrical clearance is the straight-line distance D between the edges of two adjacent welding holes 11. After the isolation part 24 is added, since it is necessary to bypass the isolation part 24 made of an insulating and high-temperature resistant material, the minimum distance between the two welding holes 11 increases. As shown in the figure, the minimum distance is the sum of the lengths D1, D2, and D3 of three line segments. That is to say, the length of the electrical clearance is D1 + D2 + D3, which is greater than D, so that the electrical clearance relatively increases, improving the insulation safety.

[0039] In an embodiment of the present application, as Figure 5 shown, along the direction towards the circuit board 10, the guiding hole 21 is in a contracted horn shape or a conical shape.

[0040] Specifically, referring to Figure 1 and Figure 5 , along the direction towards the circuit board 10, the process of the aperture of the guiding hole 21 gradually decreasing is continuous, so that when the wire harness 30 is inserted, the guiding hole 21 can reduce the frictional resistance of its inner wall on the wire harness 30, etc., quickly guide the wire harness 30 to the position of the welding hole 11, improve the assembly efficiency, and save working hours. In a specific embodiment, the process of the aperture of the guiding hole 21 gradually decreasing can be non-linear, so that the guiding hole 21 is in a contracted horn shape. In another specific embodiment, the process of the aperture of the guiding hole 21 gradually decreasing can also be linear, so that the guiding hole 21 is in a contracted conical shape.

[0041] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the insulating positioning member 20 is further provided with an elastic buckle 25, and the circuit board 10 is provided with a fixing hole 13, and the elastic buckle 25 is fixed at the fixing hole 13.

[0042] Specifically, the insulating positioning member 20 has a simple structure and a small volume, and can be fixed on the circuit board 10 through the elastic buckle 25, with wide applicability. The two elastic buckles 25 are respectively located at opposite ends of the top surface 23 of the insulating positioning member 20, and the guiding hole 21 is between the two elastic buckles 25. Correspondingly, the soldering holes 11 are also arranged between the two fixing holes 13. Fixing the elastic buckle 25 at the fixing hole 13 aligns the guiding hole 21 with at least part of the soldering holes 11. In another embodiment, the circuit board 10 and the insulating positioning member 20 can also be fixed by bolts. In other embodiments, the circuit board 10 and the insulating positioning member 20 can also be connected by soldering, etc., which will not be elaborated here.

[0043] In an embodiment of the present application as Figure 2 shown, the elastic buckle 25 includes two fixing members 251 arranged at intervals. The fixing member 251 includes a straightening portion 2511 and a limiting portion 2512, and the limiting portion 2512 is located at one end of the straightening portion 2511; after the straightening portion 2511 and the limiting portion 2512 pass through the fixing hole 13, the limiting portion 2512 abuts against the circuit board 10.

[0044] Specifically, when installing the insulating positioning member 20, the two fixing members 251 can be squeezed so that the two fixing members 251 approach each other and pass through the fixing hole 13, and then released, so that the fixing members 251 are reset and fixed at the fixing hole 13. One end of the straightening portion 2511 is arranged on the top surface 23, and the other end is connected to the fixing limiting portion 2512. After the straightening portion 2511 passes through the fixing hole 13, the limiting portion 2512 abuts against the circuit board 10, so that the insulating positioning member 20 is installed and fixed on the circuit board 10. Refer to Figure 7 , the limiting portion 2512 includes an inclined surface 2513 and a vertical surface 2514. During installation, the inclined surface 2513 can enable the limiting portion 2512 to pass through the fixing hole 13 smoothly. After passing through the fixing hole 13, the vertical surface 2514 can press against the circuit board 10 to limit the limiting portion 2512 from detaching from the fixing hole 13, so that the limiting portion 2512 is fixed. That is to say, first squeeze the straightening portion 2511 to make the limiting portion 2512 pass through the fixing hole 13, and then release the straightening portion 2511 to make the straightening portion 2511 reset. The limiting portion 2512 can abut against the surface of the circuit board 10 outside the edge of the fixing hole 13, thereby realizing the installation and fixing of the insulating positioning member 20.

[0045] Please continue to refer to Figure 1 , Figure 6 and Figure 7, in an embodiment of the present application, a clearance 40 is provided between the opposite side surfaces of the insulating positioning member 20 and the circuit board 10 to reduce the influence of the high temperature during the welding of the wire harness 30 on the positioning insulating member.

[0046] Specifically, the wire harness 30 passes through the welding hole 11 and is fixedly connected to the circuit board 10 by welding. The insulating positioning member 20 is also disposed on the circuit board 10 and is relatively close to the welding hole 11. If the insulating positioning member 20 is directly attached to the circuit board 10, even if the insulating positioning member 20 is made of a high-temperature resistant material, the high temperature generated during welding may affect the structure of the insulating positioning member 20, such as melting the guiding hole 21 or deforming the guiding hole 21. Therefore, the clearance 40 can reduce the influence of the high temperature on the insulating positioning member 20. As Figure 9 shown, the height H of the clearance 40 is the distance between the top surface 23 and the bottom surface of the circuit board 10. The height H can be greater than 1 mm, such as 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc., to further improve or avoid the influence of the high temperature during welding on the guiding hole 21 and the top surface 23.

[0047] In an embodiment of the present application, in combination with Figure 2 and Figure 7 , a recessed area 231 is provided on the top surface 23 of the insulating positioning member 20 facing the circuit board 10, and the guiding hole 21 is disposed in the recessed area 231. The recessed area 231 and the bottom surface 14 of the circuit board 10 facing the insulating positioning member 20 form the clearance 40.

[0048] Specifically, the top surface 23 is provided with a recessed area 231, and the clearance 40 is formed by the recessed area 231 and the bottom surface 14 of the circuit board 10, thereby reducing the influence of the high temperature of the welding of the wire harness 30 on the guiding hole 21 located in the recessed area 231. It can be understood that the elastic buckle 25 is disposed on the protruding area 232 of the top surface 23, forming a stepped surface with the recessed area 231. Along the direction towards the circuit board 10, the height of the recessed area 231 is less than the height of the protruding area 232, so that when connecting and fixing, even if the protruding area 232 abuts against the bottom surface 14 of the circuit board 10, the recessed area 231 can still form the clearance 40 with the bottom surface 14 of the circuit board 10. Further, along the direction towards the circuit board 10, the difference between the height of the recessed area 231 and the height of the protruding area 232 can be greater than 1 mm, so that the clearance 40 is greater than 1 mm.

[0049] In an embodiment of the present application, as Figure 1As shown, the controller 100 further includes a connector 50 and a box body 60. The wire harness 30 is disposed on the connector 50. The box body 60 is used to accommodate electronic devices such as the connector 50 and the circuit board 10 to provide a protection function. Different from the prior art, the assembly sequence of the controller 100 in the embodiment of the present application is to first install the connector 50 with the wire harness 30 on the box body 60, then install the positioning insulating member on the circuit board 10, and finally install the circuit board 10 with the welding holes 11 passing through the wire harness 30 on the box body 60 to complete the assembly. The whole process is fast and simple. The irregular wire harness 30 can be quickly guided to the specified position through the insulating positioning member 20, improving the assembly efficiency and saving working hours.

[0050] On the other hand, the present application also provides a vehicle, which includes the above-mentioned controller 100. Specifically, since the vehicle includes the controller 100 described in the above embodiment, it also has the beneficial effects of the above-mentioned controller 100, which will not be elaborated here.

[0051] It should be noted that terms such as "horizontal" and "vertical" do not mean that the components are absolutely horizontal or vertical, but can be slightly inclined; terms such as "parallel" and "perpendicular" do not mean that the fittings are absolutely parallel or perpendicular to each other, but can form a certain angular deviation. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In addition, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the products of the present application are usually placed during use. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present application.

[0052] It can be understood that the meaning of "a plurality of" in this text is at least two, such as two, three, etc., unless there are specific restrictive descriptions. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices. The term "and / or" merely describes the associated relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship.

[0053] The above description is only the implementation manner of this application, and does not limit the patent scope of this application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of this application.
