[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure.

[0024] For the convenience of description, the drawings of the present disclosure have simplified or omitted components commonly used in the art, such as external connecting lines and other components irrelevant to the description of the present disclosure. These omitted or simplified components do not affect the understanding of the content of the present disclosure by those skilled in the art.

[0025] Figure 1 A structural diagram of a part of a housing of an electrical device is shown.

[0026] As shown in Figure 1 , the electrical device includes a housing 1, which includes a positioning component 11, a positioning component 14, a fixing component 12, a fixing component 13 and a fixing component 15. These positioning components and fixing components are integrally formed with the housing. These positioning components and fixing components are generally columnar and extend vertically upward from the bottom of the housing.

[0027] Figure 2 An exploded diagram of parallel PCB boards of an electrical device is shown.

[0028] like Figure 2 As shown, a first circuit board 2 and a second circuit board 3 are arranged in parallel inside the housing 1 of the electrical device for controlling the power transmission of the electrical device. The first circuit board 2 and the second circuit board 3 are mounted parallel to each other inside the housing 1, with the first circuit board 2 located below the second circuit board 3. Figure 1 The positioning and fixing components shown are used to mount the first circuit board 2 and the second circuit board 3. Specifically, the fixing component 15 is used to fix the second circuit board 3. Positioning components 11 and 14 are used to position the first circuit board 2, and fixing components 12 and 13 are used to fix the first circuit board 2.

[0029] However, these positioning and fixing components are numerous and will occupy the mounting space of the components on the PCB. They may conflict with the components on the PCB, resulting in insufficient space to place the components.

[0030] To solve the above problems, Figure 1 The positioning component 14 and the fixing component 15 shown are combined into a new component (hereinafter referred to as the first positioning component 10), which enables the first circuit board 2 to be positioned and the second circuit board 3 to be fixed at the same time, thereby saving more space for the PCB and simplifying the housing structure of the electrical equipment.

[0031] Figure 3 A schematic diagram of the structure of a first positioning component 10 provided in at least one embodiment of the present disclosure is shown.

[0032] like Figure 3 As shown, the first positioning component 10 is generally cylindrical and includes a first positioning structure 101 connected to the housing 1 and a second positioning structure 102 located on the first positioning structure 101. For example, in one embodiment, the first positioning structure 101 is a frustum structure serving as a base, and the second positioning structure 102 is a cylindrical structure located on the first positioning structure 101. The first positioning structure 101 and the second positioning structure 102 are coaxial, and the diameter of the second positioning structure 102 is smaller than the diameter of the upper surface of the first positioning structure 101. The first positioning structure 101 and the second positioning structure 102 are integrally formed. A first mounting hole 103 is formed on the upper surface of the second positioning structure 102, and the depth of the first mounting hole 103 is related to the size of the mating mounting component.

[0033] It should be noted that, Figure 3 The first positioning component shown is merely an example. The first positioning component can also be other structures. For example, both the first positioning structure and the second positioning structure can be cylindrical structures, as long as they can simultaneously achieve the positioning of the first circuit board and the fixation of the second circuit board. This disclosure does not impose any restrictions on this.

[0034] Figure 4 An assembly view of the first positioning component 10 provided by at least one embodiment of the present disclosure is shown.

[0035] As shown in Figure 4 , the first circuit board 2 is provided with a first positioning hole 21, and the second circuit board 3 is provided with a second mounting hole 31. The second positioning structure 102 of the first positioning component 10 passes through the first positioning hole 21 to position the first circuit board 2, and the structure part near the first positioning hole 21 of the first circuit board 2 abuts on the first positioning structure 101. The first mounting hole 103 opened on the first positioning component 10 and the second mounting hole 31 on the second circuit board 3 match each other to fix the second circuit board 3 on the first positioning component 10 by fasteners. For example, the fasteners can be screws, which are screwed into the first mounting hole 103 and the second mounting hole 31.

[0036] For example, in one embodiment of the present disclosure, the radius of the first positioning hole 21 is 0.1mm-0.2mm larger than the radius of the second positioning structure 102.

[0037] Figure 5 is a structural view of a part of the housing of the electrical equipment provided by at least one embodiment of the present disclosure.

[0038] As shown in Figure 5 , the electrical equipment includes a housing 1, which includes a first positioning component 10, a second positioning component 11, a fixing component 12 and a fixing component 13. These positioning components and fixing components are integrally formed with the housing 1. These positioning components and fixing components are generally columnar and vertically extend upward from the bottom of the housing 1. The second positioning component 11 has no change in position and structure compared with the positioning component 11 shown in Figure 1 , the fixing component 12 and the fixing component 13 have no change in position and structure compared with the position and structure shown in Figure 1 , the first positioning component 10 replaces the positioning component 14 and the fixing component 15 shown in Figure 1 , and can simultaneously realize the positioning of the first circuit board 2 and the fixing of the second circuit board 3.

[0039] The second positioning component 11 includes a third positioning structure 111 connected with the housing 1 and a fourth positioning structure 112 located on the third positioning structure 111, and each of the fixing component 12 and the fixing component 13 is provided with a third mounting hole 121.

[0040] It should be noted that the housing of the electrical equipment of the present disclosure can also include other positioning components and fixing components, which are not limited by the present disclosure.

[0041] Figure 6A mounting diagram of parallel PCB boards of an electrical device provided by at least one embodiment of the present disclosure is shown.

[0042] As shown in Figure 6 , the electrical device further comprises a first circuit board 2 and a second circuit board 3 Figure 6 (not shown in the figure), the first positioning component 10 is used to simultaneously position the first circuit board 2 and fix the second circuit board 3, the second positioning component 11 is used to position the first circuit board 2, and the fixing component 12 and the fixing component 13 are used to fix the first circuit board 2.

[0043] As can be seen from Figure 6 , since the first positioning component 10 simultaneously realizes two functions, the number of required components is reduced, more space can be saved for the printed circuit board and the shell structure of the electrical device is simplified.

[0044] As known from the above, the second positioning structure 102 of the first positioning component 10 passes through the first positioning hole 21 of the first circuit board 2, thereby realizing the positioning of the first circuit board 2. As shown in Figure 6 , the first circuit board 2 is further provided with a second positioning hole 22 and a fourth mounting hole 23. The second positioning hole 22 is used to cooperate with the fourth positioning structure 112 of the second positioning component 11, and the fourth mounting hole 23 cooperates with the third mounting hole 121 provided on the fixing component 12 and the fixing component 13, so as to fix the first circuit board 2 by passing fasteners through the fourth mounting hole 23 and the third mounting hole 121. For example, the fastener can be a screw, which is screwed into the fourth mounting hole 23 and the third mounting hole 121.

[0045] For example, in one embodiment of the present disclosure, the second positioning hole 22 is a waist-shaped hole, and the fourth positioning structure 112 passes through the second positioning hole 22 and abuts against the edge of the circular hole on one side of the second positioning hole 22. For example, the fourth positioning structure 112 abuts against the edge of the circular hole of the second positioning hole 22 close to the first positioning component 10.

[0046] For example, in one embodiment of the present disclosure, the distribution positions of the second positioning component 11 and the first positioning component 10 are approximately parallel to the diagonal positions of the first circuit board 2.

[0047] For example, in one embodiment of the present disclosure, the extension line of the center line of the second positioning hole 22 passes through the center of the first positioning hole 21.

[0048] By the first positioning component 10 and the second positioning component 11 provided by the embodiments of the present disclosure, the translation and rotation of the first circuit board 2 in the plane where it is located can be prevented. Figure 6 The assembly structure of the first circuit board 2 shown can prevent the first circuit board 2 from moving in various directions, thereby being able to stably fix the first circuit board 2.

[0049] According to another aspect of the present disclosure, an electric drive system is proposed, comprising an electrical device as described above. It is to be understood that the electric drive system of the present disclosure also has the advantages described above with respect to the electrical device.

[0050] According to another aspect of the present disclosure, a vehicle is proposed, comprising an electrical device and / or an electric drive system as described before. The vehicle can be an Electrified Vehicle, such as a Battery Electric Vehicle (BEV), a Hybrid Electric Vehicle (HEV), a Plug-in Hybrid Electric Vehicle (PHEV), a Range extended EV, a Fuel Cell Electric Vehicle (FCEV). The vehicle can also be a hydrogen energy vehicle. It is to be understood that the vehicle of the present disclosure also has the advantages described above with respect to the electrical device.
