The switching device includes a first terminal group, comprising a first positive terminal and a first negative terminal, with a first gap space defined between the first positive and first negative terminals. Each of the first positive and first negative terminals has a first fixing hole. The bus capacitor includes a second terminal group, comprising a second positive terminal and a second negative terminal, the second positive terminal being electrically connected to the first positive terminal, and the second negative terminal being electrically connected to the second positive terminal. A second gap space is defined between the second positive and second negative terminals, communicating with the first gap space. Each of the second positive and second negative terminals has a second fixing hole, corresponding one-to-one with the first fixing holes.

The insulating component includes a fixing portion and an insulating portion, the insulating portion being connected to the fixing portion. The fixing portion has a third fixing hole, corresponding to at least one first fixing hole of the first terminal group. The insulating portion is located within the first and second gap spaces. In this case, the fastener in the first fixing hole corresponding to the third fixing hole passes through the third fixing hole.

[0005] Since the insulation components of the aforementioned electrical components are fixed by the same fasteners as the switching devices and bus capacitors, there is no need to add additional fixing structures to install the insulation components on other components (such as the electrical control housing), which saves the installation steps of installing the insulation components on other components and improves the assembly efficiency of the electrical components.

[0006] In one embodiment, there are at least two first terminal groups and at least two second terminal groups, with each first terminal group corresponding to one of the second terminal groups. There are at least two insulating portions, each corresponding to a first gap space and a second gap space, and located within the corresponding first gap space and second gap space.

The insulating member also includes a connecting portion, and there are at least two fixing portions, each located on one side of the first fixing hole along the first direction and connected by the connecting portion.

[0008] In one embodiment, the connecting portion is located on the side of the first terminal group away from the second terminal group along the second direction; or, the connecting portion is located on the side of the second terminal group away from the first terminal group along the second direction.

[0009] In one embodiment, the connecting part is provided with an operating hole, which passes through the connecting part in a second direction and is opposite to the corresponding first fixing hole in the second direction.

[0010] In one embodiment, the connecting portion and the first terminal group are spaced apart along a second direction, and the connecting portion and the second terminal group are also spaced apart along a second direction.

[0011] In one embodiment, the insulating portion protrudes from the side of the fixing portion away from the first terminal group. The insulating member also includes a protective portion, which corresponds one-to-one with the fixing portion and protrudes from the corresponding fixing portion on the side away from the first terminal group. The protective portion and the insulating portion form a groove, which has a notch opposite to the fixing portion. The fastener includes a connecting rod and a positioning head. The connecting rod passes through the first fixing hole and the second fixing hole, and the positioning head corresponding to the fixing portion is located in the groove.

[0012] In one embodiment, the fastener includes a connecting rod and a positioning head. The connecting rod passes through a first fixing hole and a second fixing hole, and a connecting rod in the first fixing hole corresponding to a third fixing hole passes through the third fixing hole. The positioning head abuts against a first terminal group or a second terminal group. The electrical assembly also includes a locking member sleeved on the end of the connecting rod away from the positioning head.

[0013] In one embodiment, the locking member is connected to the side of the second terminal group opposite to the first terminal group; or, the locking member is connected to the side of the first terminal group opposite to the second terminal group.

[0030] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Example Figure 1 This is a schematic diagram of a vehicle 1000 in one embodiment of this application; Figure 2 for Figure 1 A perspective view of the electrical component 100 in the illustrated embodiment.

[0032] See Figure 1 and Figure 2 This embodiment provides a vehicle 1000, including a body 200 and an electric drive assembly. The electric drive assembly is disposed on the body 200 and includes an electrical component 100.

[0033] Optionally, the electric drive assembly includes a motor, an electronic control system, and a transmission system. The electronic control system converts the direct current (DC) discharged from the power battery into alternating current (AC), enabling the motor to operate. The motor converts electrical energy into mechanical energy, which is then transmitted to the wheels via the transmission system, generating driving force to propel the vehicle. The electronic control system includes an electrical component 100, which includes switching devices 10, such as IGBTs (Insulated Gate Bipolar Transistors). The transmission system includes a speed reducer. In use, when DC current passes through the switching devices 10, the direction and frequency of the current flow are changed by switching different combinations of the switching devices 10, thereby outputting alternating current.

[0034] Figure 3 for Figure 2 A top view of the electrical component 100 in the illustrated embodiment; Figure 4 for Figure 2 Exploded view of the insulating member 40, the first terminal group 11, and the second terminal group 21 in the illustrated embodiment; Figure 5 for Figure 2 A partial structural schematic diagram of the electrical component 100 in the illustrated embodiment; Figure 6 for Figure 2 A perspective view of the electrical component 100 in the illustrated embodiment from another viewpoint; Figure 7 for Figure 2 A perspective view of the insulating member 40 in the illustrated embodiment; Figure 8 for Figure 2 A perspective view of the insulating element 40 in the illustrated embodiment from another angle.

[0035] See Figure 2 and Figure 3 The electrical component 100 provided in this embodiment includes a switching device 10, a bus capacitor 20, a fastener 30, and an insulating component 40. For example... Figure 4 and Figure 5 As shown, the switching device 10 includes a first terminal group 11, which includes a first positive terminal 111 and a first negative terminal 112. A first gap space 11a is defined between the first positive terminal 111 and the first negative terminal 112. Each of the first positive terminal 111 and the first negative terminal 112 has a first fixing hole 11b. Figure 4 and Figure 6 As shown, the bus capacitor 20 includes a second terminal group 21, which includes a second positive terminal 211 and a second negative terminal 212. The second positive terminal 211 is electrically connected to the first positive terminal 111, and the second negative terminal 212 is electrically connected to the second positive terminal 211. A second gap space 21a is defined between the second positive terminal 211 and the second negative terminal 212, and the second gap space 21a communicates with the first gap space 11a. Each of the second positive terminal 211 and the second negative terminal 212 has a second fixing hole 21b, which corresponds one-to-one with the first fixing hole 11b. Fasteners 30 correspond one-to-one with the first fixing hole 11b and the second fixing hole 21b, and are inserted through the corresponding first fixing hole 11b and second fixing hole 21b. Figure 7 and Figure 8 As shown, the insulating member 40 includes a fixing part 41 and an insulating part 42. The insulating part 42 is connected to the fixing part 41. The fixing part 41 is provided with a third fixing hole 41a, which corresponds to at least one first fixing hole 11b of the first terminal group 11. The insulating part 42 is located within the first interval space 11a and the second interval space 21a. A fastener 30 corresponding to the first fixing hole 11b passes through the third fixing hole 41a.

[0036] The aforementioned electrical components 100, with fasteners 30 passing through corresponding first fixing holes 11b and second fixing holes 21b, securely connect the first positive terminal 111 and the second positive terminal 211, and securely connect the first negative terminal 112 and the second negative terminal 212, thereby ensuring the reliability of the electrical connection. By providing an insulating member 40, with its insulating portion 42 located within the first and second spacing spaces 11a and 21a, the electrical clearance between the first positive terminal 111 and the first negative terminal 112, and between the second positive terminal 211 and the second negative terminal 212, is increased. This reduces the risk of arcing and short circuits between the first positive terminal 111 and the second negative terminal 212 caused by crosstalk between complex high-voltage systems, foreign objects at the manufacturing end, or condensation in the operating environment, thereby improving the reliability and safety of the vehicle 1000 when powered on. Furthermore, by providing the insulating portion 42, the designed gap between the first positive terminal 111 and the first negative terminal 112 can be reduced, which is beneficial for increasing power density. Optionally, when the insulating portion 42 is disposed within the first spacing space 11a and the second spacing space 21a, since the insulating portion 42 is non-conductive, the first positive terminal 111 and the first negative terminal 112 can contact the insulating portion 42 to improve the overall structural compactness. In other embodiments, the first positive terminal 111 and the first negative terminal 112 may also be spaced apart from the insulating portion 42 to improve insulation performance.

[0037] The insulating component 40 also includes a fixing part 41, which has a third fixing hole 41a. A fastener 30 corresponding to the third fixing hole 41a passes through the third fixing hole 41a, forming a tight connection between the insulating component 40 and the corresponding first positive terminal 111 and / or first negative terminal 112, thereby achieving the installation and fixing of the insulating component 40. Furthermore, since the insulating component 40 shares the same fasteners 30 for fixing the switching device 10 and the bus capacitor 20, there is no need to add an additional fixing structure to install the insulating component 40 onto other components (such as the electrical control housing). This reduces the volume of the insulating component 40, achieving a lightweight structure, reducing material costs, and saving the installation steps of mounting the insulating component 40 onto other components, improving the assembly efficiency of the electrical assembly 100, and ensuring that the installation and fixing of the insulating component 40 is not affected by other components such as the electrical control housing. Therefore, the insulating component 40 can be applied to different electrical controls of the same model of switching device 10. It should be noted that... Figure 1 This is only used to illustrate the position of electrical component 100 relative to vehicle 1000 and does not represent the actual structure of electrical component 100.

[0038] Optionally, the first positive terminal 111, the first negative terminal 112, the second positive terminal 211, and the second negative terminal 212 can each be a copper busbar.

[0039] It should be noted that the related technology also provides an electrical component that isolates the first positive terminal and the first negative terminal by applying insulating adhesive, but this is difficult to guarantee consistency and affects production efficiency. The aforementioned electrical component 100 improves production efficiency and consistency by incorporating an insulating element 40.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, there are at least two first terminal groups 11 and at least two second terminal groups 21, with each first terminal group 11 corresponding to one second terminal group 21. There are at least two insulating portions 42, each corresponding to one first interval space 11a and one second interval space 21a, and located within the corresponding first interval space 11a and second interval space 21a. There is at least one fixing portion 41, with each fixing portion 41 corresponding to at least one first terminal group 11. This makes the structure of the insulating member 40 an integral whole, facilitating the overall fixing of the insulating member 40, which is easier than a separate structure for installation and fixing. The insulating portions 42 correspond one-to-one with the first terminal groups 11, ensuring that each first interval space 11a and each second interval space 21a has an insulating portion 42, thus ensuring the reliability of electrical insulation. It should be noted that the connection of at least two fixing portions 41 to each other can refer to a direct connection of at least two fixing portions 41, or an indirect connection of at least two fixing portions 41 through a central portion.

[0041] In some embodiments, there are two fixing portions 41 to reliably fix the insulating member 40 and prevent displacement or rotation. When there are two fixing portions 41 and more than two insulating portions 42, the insulating portions 42 are directly connected to the fixing portions 41 or connected to the central portion between two fixing portions 41. In other embodiments, there may also be three, four, or other numbers of fixing portions 41 to further improve the fixing reliability of the insulating member 40.

[0042] Optionally, such as Figure 4 As shown, there are three first terminal groups 11 and three second terminal groups 21. The three first terminal groups 11 are U, V, and W phases respectively, and the three second terminal groups 21 are U, V, and W phases respectively. The first terminal groups 11 and second terminal groups 21 of the same phase correspond to each other. Optionally, at least two of the U, V, and W phases correspond to the fixing part 41. The fixing part 41 can be connected to the first positive terminal 111 of the corresponding first terminal group 11, or it can be connected to the first negative terminal 112 of the corresponding first terminal group 11.

[0043] In some embodiments, such as Figure 7As shown, the fixing part 41 is provided with a boss 411, and the boss 411 is provided with a third fixing hole 41a, so as to increase the thickness of the fixing part 41 at the third fixing hole 41a, reduce the risk of cracking or deformation of the insulating part 40, and the boss 411 can support a larger tightening torque to prevent the fastener 30 (see Figure 6 Loose.

[0044] In some embodiments, such as Figure 4 and Figure 7 As shown, there are multiple first terminal groups 11 and multiple second terminal groups 21. The multiple first terminal groups 11 are arranged along a first direction A, and the multiple second terminal groups 21 are arranged along the first direction A. The fixing part 41, the first terminal groups 11, and the second terminal groups 21 are arranged along a second direction B, wherein the second direction B intersects with the first direction A. The insulating member 40 also includes a connecting part 43, and there are at least two fixing parts 41, each located in a first fixing hole 11b (see...). Figure 5 Along both sides of the first direction A, and connected by the connecting part 43. This allows at least two adjacent fixing parts 41 to be spaced apart by at least one first fixing hole 11b, thereby reducing the number of fixing parts 41, improving assembly efficiency, and allowing at least two fixing parts 41 to be fixed to different first terminal groups 11 respectively, distributing the force at different fixing parts 41 mounting points, and improving the structural reliability of the electrical assembly 100. Optionally, the second direction B is perpendicular to the first direction A. Optionally, the fixing part 41 can be on the side of the first terminal group 11 away from the second terminal group 21, and the fixing part 41 can also be on the side of the second terminal group 21 away from the first terminal group 11. It should be noted that in this embodiment, "multiple" refers to at least three.

[0045] In some embodiments, such as Figure 3 As shown, the switching device 10 and the bus capacitor 20 are distributed along a third direction C and are respectively fixed on the electrical control housing (not shown). The third direction C is perpendicular to the first direction A and the second direction B, respectively. It should be noted that perpendicularity within 5° or the angle between two adjacent directions between 85° and 95° can be considered perpendicular.

[0046] In some embodiments, such as Figure 7 As shown, along the first direction A, a connecting portion 43 is provided between any two adjacent fixing portions 41, making the distribution of fixing portions 41 and insulating portions 42 more reasonable and improving the structural strength of the insulating member 40. In this embodiment, there are three fixing portions 41 and two insulating portions 42. Furthermore, due to the asymmetrical structure of the insulating member 40, production error prevention can be achieved.

[0047] In some embodiments, such as Figure 5As shown, the connecting portion 43 is located on the side of the first terminal group 11 away from the second terminal group 21 along the second direction B, so as to reduce the size of the insulating member 40 along the third direction C, making the insulating member 40 suitable for a smaller installation space. In other embodiments, the connecting portion 43 is located on the side of the second terminal group 21 away from the first terminal group 11 along the second direction B (not shown).

[0048] In some embodiments, such as Figure 5 and Figure 7 As shown, the connecting part 43 is provided with an operating hole 43a. The operating hole 43a passes through the connecting part 43 along the second direction B, and the operating hole 43a is opposite to the corresponding first fixing hole 11b along the second direction B. The tightening tool used to tighten the fastener 30 can move in and out of the operating hole 43a, thereby tightening the fastener 30 at the first fixing hole 11b corresponding to the connecting part 43, which facilitates the operation of tightening the fastener 30.

[0049] In some embodiments, the connecting portion 43 is spaced apart from the first terminal group 11 along the second direction B, and the connecting portion 43 is spaced apart from the second terminal group 21 along the second direction B, so as to reserve operating space for tightening the fastener 30.

[0050] In some embodiments, such as Figure 5 and Figure 7 As shown, the insulating portion 42 protrudes from the fixing portion 41 on the side away from the first terminal group 11. The insulating member 40 also includes a protective portion 44, which corresponds one-to-one with the fixing portion 41 and protrudes from the corresponding fixing portion 41 on the side away from the first terminal group 11. The protective portion 44 and the insulating portion 42 form a groove 40a, which has a slot 40b opposite to the fixing portion 41. Figure 6 As shown, the fastener 30 includes a connecting rod 31 and a positioning head 32. The connecting rod 31 passes through the first fixing hole 11b and the second fixing hole 21b, and the positioning head 32, corresponding to the fixing part 41, is located in the groove 40a. Thus, by providing the protective part 44, the structural stability of the insulating component 40 is improved, and the groove 40a is formed by the protective part 44 and the insulating part 42, providing operating space for the tightening tool to prevent accidental contact with surrounding live parts. Optionally, the connecting rod 31 can be a screw, and the positioning head 32 can be a bolt head. The insulating part 42 and the protective part 44 extend along the second direction B towards the side away from the first terminal group 11 to form the groove 40a, and the groove opening 40b is opposite to the fixing part 41 along the second direction B.

[0051] Figure 9 for Figure 2 Side view of the insulating member 40 in the illustrated embodiment.

[0052] In some embodiments, combined with Figure 5 and Figure 9As shown, one end of the connecting part 43 along the first direction A is connected to one end of the insulating part 42 along the second direction B away from the second terminal group 21, and the other end of the connecting part 43 along the first direction A is connected to the side of the protective part 44 along the second direction B away from the second terminal group 21, so as to increase the gap between the connecting part 43 and the first terminal group 11 along the second direction B, which facilitates the operation of tightening the fastener 30.

[0053] Figure 10 for Figure 1 A partial structural schematic diagram of the electrical component 100 in the illustrated embodiment from another perspective.

[0054] In some embodiments, combined with Figure 5 and Figure 10 As shown, the fastener 30 includes a connecting rod 31 and a positioning head 32. The connecting rod 31 passes through the first fixing hole 11b and the second fixing hole 21b, and the connecting rod 31 in the first fixing hole 11b corresponding to the third fixing hole 41a passes through the third fixing hole 41a. The positioning head 32 abuts against the first terminal group 11 or the second terminal group 21. The electrical assembly 100 also includes a locking member 50 (such as a nut), which is sleeved on the end of the connecting rod 31 away from the positioning head 32 to improve the connection reliability of the first terminal group 11 and the second terminal group 21.

[0055] In some embodiments, such as Figure 10 As shown, the locking member 50 is connected to the side of the second terminal group 21 opposite to the first terminal group 11, so that when installing the fastener 30, it can be inserted and tightened only from the side of the first terminal group 11 away from the second terminal group 21, improving assembly efficiency. Optionally, the connection method between the locking member 50 and the second terminal group 21 includes, but is not limited to, welding connection / adhesive connection. In some other embodiments, the locking member 50 is connected to the side of the first terminal group 11 opposite to the second terminal group 21 (not shown).

[0056] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
