Description

Technical Field

[0001] This disclosure relates to an electrical device, such as an inverter for a vehicle. This disclosure also relates to an electric drive assembly system including the electrical device and a vehicle including the electric drive assembly system. Background Technology

[0002] In known electrical devices, such as inverters used in vehicles, there is a housing and various electrical components housed within it. Electromagnetic isolation is required between some of these components, such as between low-voltage and high-voltage components, to prevent electromagnetic interference. Existing technology involves integrally incorporating an electromagnetic interference isolation wall onto the housing, for example, an isolation wall extending from the bottom or side wall of the housing into the interior. However, this integral isolation wall design complicates the housing structure, resulting in higher design and manufacturing costs, poor versatility, and low cost-effectiveness. Furthermore, to ensure the proper installation of electrical components within the housing, especially when the installation involves horizontal displacement, such as displacement parallel to the bottom wall, or when the electrical component needs to be installed through holes in the housing sidewall so that one part of the electrical component is inside the housing and the other part is outside the housing, it is necessary to ensure that the housing, while having an integrated electromagnetic interference isolation wall, still has sufficient installation margin to allow for the installation displacement of the electrical component, thereby ensuring the feasibility of the installation. This would result in an excessively large overall size of the housing, creating too much empty space inside the housing, making it impossible to achieve a compact overall electrical device, which limits the usability of the electrical device in space-constrained environments.

[0003] Therefore, a completely new solution is needed to address at least one of the aforementioned technical problems and bring about other technical benefits. Summary of the Invention

[0004] According to one aspect, this disclosure provides an electrical device. According to an exemplary embodiment, the electrical device includes:

[0005] The housing includes a housing periphery wall and a bottom wall, and an installation space surrounded by the housing periphery wall and the bottom wall, the installation space including a first receiving portion and a second receiving portion;

[0006] A high-voltage electronic unit and a low-voltage electronic unit are disposed in the first receiving portion;

[0007] An additional electronic unit is at least partially disposed in the second receiving portion;

[0008] An electromagnetic interference isolation bracket includes a first part, which is disposed in a first receiving portion and located between the high-voltage electronic unit and the low-voltage electronic unit to isolate the high-voltage electronic unit and the low-voltage electronic unit from each other;

[0009] The electromagnetic interference isolation bracket further includes a second part, which is configured to at least partially surround the additional electronic unit to form electromagnetic shielding for the additional electronic unit.

[0010] In other words, in the electrical device proposed in this disclosure, an electromagnetic interference (EMI) isolation bracket is used to ensure isolation between high-voltage (i.e., high-voltage) electronic units and low-voltage (i.e., low-voltage) electronic units, especially EMI isolation, and to achieve electromagnetic shielding for additional electronic units. Therefore, in the electrical device proposed in this disclosure, it is unnecessary to implement individual integrated EMI isolation walls on the housing to achieve EMI shielding for multiple different electronic units, thereby simplifying the structure, design, and manufacturing of the housing and improving cost-effectiveness. Furthermore, since there are no longer EMI isolation walls integrally formed with the housing in the installation space of the housing, the installation interference of EMI isolation walls on certain electronic units is eliminated, thus eliminating the need for pre-reserved installation allowances and ensuring effective utilization of the housing's installation space, resulting in a compact overall electrical device. More specifically, the electrical device of this disclosure allows the electronic units to be installed in their respective receiving portions of the housing before the EMI isolation bracket is installed.

[0011] According to different embodiments, the electrical device proposed in this disclosure may include one or more of the following further developments.

[0012] According to some embodiments, the additional electronic unit is positioned close to the periphery of the housing and has an interface extending through the periphery of the housing. The electrical device of this disclosure allows for convenient installation of an electronic unit extending through the periphery of the housing in a compact structure, thereby ensuring the required performance of the electrical device.

[0013] According to some embodiments, the second portion includes a top wall and at least one electromagnetic shielding peripheral wall extending transversely to the top wall, the at least one electromagnetic shielding peripheral wall being configured to at least partially surround the additional electronic unit. Thus, in the electrical device of this disclosure, the second portion of the electromagnetic interference isolation bracket can form multifaceted electromagnetic shielding around the additional electronic unit, ensuring the normal operation and performance of the additional electronic unit.

[0014] According to some embodiments, the at least one electromagnetic shielding peripheral wall, together with at least a portion of the housing peripheral wall, forms an electromagnetic shielding enclosure structure surrounding at least a portion of the additional electronic unit. More specifically, the housing peripheral wall can provide a certain degree of electromagnetic shielding for the additional electronic unit, which on the one hand allows for full-dimensional electromagnetic interference shielding of the additional electronic unit with saved materials and reduced components, and on the other hand further promotes the structural compactness of the electrical device.

[0015] According to some embodiments, the electrical device further includes conductive adhesive disposed between the second portion and the housing. The conductive adhesive can improve the electromagnetic interference shielding effect on additional electronic units. Additionally, the conductive adhesive also helps to position the electromagnetic interference isolation bracket relative to the housing.

[0016] According to some embodiments, the housing does not include an electromagnetic shielding wall extending upwards from the bottom wall for attaching electronic units. This ensures that there are no structures in the housing's mounting space that could obstruct the installation of the electronic units.

[0017] According to some embodiments, the additional electronic unit includes an EMC (Electromagnetic Compatibility) filter plate disposed in the second receiving portion. This allows for good electromagnetic interference shielding of the EMC filter plate.

[0018] According to some embodiments, the electromagnetic interference isolation bracket is a single piece. This allows for simplified assembly of electrical devices, thereby reducing assembly costs and improving assembly efficiency.

[0019] According to some embodiments, the low-voltage electronic unit is a control unit, and the high-voltage electronic unit includes power components.

[0020] According to some embodiments, the mounting space further includes a third housing, and the electrical device includes an additional high-voltage electronic unit disposed in the third housing. The electromagnetic interference isolation bracket is also configured to isolate the third housing from the second housing. This further ensures effective electromagnetic interference isolation between different electronic units with a compact structure and a reduced number of components.

[0021] According to some embodiments, the electromagnetic interference isolation bracket further includes a third portion extending laterally to the first portion, the third portion being disposed between the third receiving portion and the first receiving portion to isolate the third receiving portion from the first receiving portion. This allows for effective electromagnetic interference isolation between different electronic units with a simple structure.

[0022] According to some embodiments, the electrical device is an inverter.

[0023] Another aspect of this disclosure proposes an electric drive assembly system that includes the electrical device according to any one of the above embodiments, and thus has corresponding technical effects and advantages.

[0024] Another aspect of this disclosure proposes a vehicle that includes the electric drive assembly system described above. Attached Figure Description

To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

For example, without departing from the scope of this disclosure, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component.

[0060] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the disclosed product is in use, or the orientation or positional relationship commonly understood by those skilled in the art.

Therefore, they should not be construed as limitations on this disclosure.

[0061] This disclosure provides an electrical device 10. For example... Figure 1-4 As shown in Figures 8 and 9, according to an exemplary embodiment, the electrical device 10 includes a housing 100. (As illustrated in Figure 8) Figure 1 and 4 As shown, the housing 100 may include a bottom wall 120 and a housing peripheral wall 110, the housing peripheral wall 110 extending, for example, transversely to (i.e., not parallel to, but including perpendicular to) the bottom wall 120. The housing 100 includes a mounting space at least partially surrounded by the housing peripheral wall 110 and the bottom wall 120, the mounting space may include different receiving portions, more specifically including at least a first receiving portion 130 and a second receiving portion 140. For example, different electrical components or electronic units may be respectively received in different receiving portions.

[0062] like Figure 2-3 As shown in Figures 7-8, according to an exemplary embodiment, the electrical device 10 may include different electronic units located in the mounting space of the housing 100, and includes an electromagnetic interference isolation bracket 500, which may be configured to achieve electromagnetic interference isolation between different electronic units to ensure the operational performance of each electronic unit.

[0063] According to one embodiment, such as Figure 2-3As shown in Figures 7-8, the electrical device 10 may include a high-voltage electronic unit 300 and a low-voltage electronic unit 200. The electromagnetic interference isolation bracket 500 may include a first portion 510 configured to be located between the high-voltage electronic unit 300 and the low-voltage electronic unit 200 to isolate them from each other. According to an exemplary embodiment, both the high-voltage electronic unit 300 and the low-voltage electronic unit 200 are disposed in a first receiving portion 130 of the mounting space. More specifically, the first portion 510 of the electromagnetic interference isolation bracket 500 is also located in the first receiving portion 130. According to an exemplary embodiment, the low-voltage electronic unit 200 is a control unit, such as a circuit board including various control elements and circuits. Additionally or alternatively, the high-voltage electronic unit 300 includes power components, such as various power transistors. According to an exemplary embodiment, as... Figure 7-8 As shown, in the first receiving portion 130, the high-voltage electronic unit 300 and the low-voltage electronic unit 200 can be stacked in a vertical direction relative to the bottom wall 120. The first portion 510 of the electromagnetic interference isolation bracket 500 is located between the high-voltage electronic unit 300 and the low-voltage electronic unit 200, and more specifically, the high-voltage electronic unit 300 is configured to be closer to the bottom wall 120 than the low-voltage electronic unit 200. In some embodiments, the bottom wall 120 of the housing 100 participates in defining the first receiving portion 130. According to some embodiments, such as Figure 2-3 As shown in Figure 7, the electrical device 10 may further include an additional electronic unit 400, and the electromagnetic interference isolation bracket 500 may be configured to shield the additional electronic unit 400 from electromagnetic interference. In some embodiments, the additional electronic unit 400 is at least partially disposed in a second receiving portion 140 of the mounting space of the housing 100, and the electromagnetic interference isolation bracket 500 may include a second portion 520 configured to at least partially surround the additional electronic unit 400 to form electromagnetic shielding for the additional electronic unit 400, thereby ensuring that the additional electronic unit 400 is not subject to electromagnetic interference from other electronic units. In some embodiments, the second portion 520 is at least partially or completely disposed in the second receiving portion 140. In some embodiments, the bottom wall 120 of the housing 100 participates in defining the second receiving portion 140.

[0064] That is, in the electrical device 10 proposed in this disclosure, by setting up an electromagnetic interference isolation bracket 500, isolation between the high-voltage (i.e., high-voltage) electronic unit 300 and the low-voltage (i.e., low-voltage) electronic unit 200 is ensured, especially electromagnetic interference isolation, and electromagnetic shielding of the additional electronic unit 400 is achieved on the other hand. Therefore, in the electrical device 10 proposed in this disclosure, it is not necessary to implement individual integrated electromagnetic interference isolation walls on the housing 100 to achieve electromagnetic interference shielding for multiple different electronic units, thereby simplifying the structure, design, and manufacturing of the housing 100 and improving cost-effectiveness. Furthermore, since there are no longer electromagnetic interference isolation walls integrally formed with the housing 100 in the installation space of the housing 100, the installation interference of electromagnetic interference isolation walls on certain electronic units is correspondingly eliminated, thus eliminating the need to reserve installation slack and ensuring effective utilization of the installation space of the housing 100, thereby achieving a compact overall structure for the electrical device 10. More specifically, the electrical device 10 of this disclosure allows the electronic units to be installed in their respective receiving portions of the housing 100 before the electromagnetic interference isolation bracket 500 is installed.

[0065] According to some embodiments, the housing 100 does not include an electromagnetic shielding wall extending upward from the bottom wall 120 for attaching the electronic unit 400. This ensures that there are no structures in the mounting space of the housing 100 that could obstruct the installation of the electronic unit.

[0066] According to some embodiments, such as Figure 1-2 As shown, the additional electronic unit 400 is positioned close to the housing peripheral wall 110 and has an interface 410 extending through the housing peripheral wall 110. Exemplarily, the interface 410 can be used for electrical or signal connection with other electrical components. More specifically, the interface 410 of the additional electronic unit 400 is connected to the rest of the additional electronic unit 400, for example, integrally mounted or assembled together. Therefore, the additional electronic unit 400 needs to be installed through an opening in the housing peripheral wall 110, more specifically, its interface 410 extends from inside the housing 100 through the opening in the housing peripheral wall 110 to the outside of the housing 100. Thus, the installation of the additional electronic unit 400 involves a displacement parallel to the bottom wall 120. The electrical device 10 of this disclosure allows sufficient installation margin in the installation space to ensure horizontal installation displacement of the additional electronic unit 400 by eliminating an electromagnetic interference isolation wall integrally mounted with the housing 100. This allows for convenient installation of the additional electronic unit 400 extending through the housing peripheral wall 110 in a compact structure, thereby ensuring the desired performance of the electrical device 10. According to some embodiments, the additional electronic unit 400 may include an EMC filter plate 420 disposed in the second receiving portion 140. This allows for good electromagnetic interference shielding of the EMC filter plate 420.

[0067] According to some embodiments, such as Figure 2-3 As shown in Figures 5-8, the second portion 520 of the electromagnetic interference isolation bracket 500 may include a top wall 521 and at least one electromagnetic shielding peripheral wall 522 extending transversely to the top wall 521, the at least one electromagnetic shielding peripheral wall 522 being configured to at least partially surround the additional electronic unit 400. In some embodiments, the number of electromagnetic shielding peripheral walls 522 may be determined based on the overall profile of the additional electronic unit 400 and the required installation space, such that the electromagnetic shielding peripheral walls 522 can follow the overall profile of the additional electronic unit 400, thereby ensuring electromagnetic interference shielding of the additional electronic unit 400 while further promoting the effective utilization of the installation space within the housing 100, thereby further contributing to the overall structural compactness of the electrical device 10. Thus, in the electrical device 10 of this disclosure, the second portion 520 of the electromagnetic interference isolation bracket 500 can form a multifaceted electromagnetic shielding structure around the additional electronic unit 400, ensuring the normal operation and performance of the additional electronic unit 400. According to some embodiments, such as Figure 2-3 As shown in Figures 5-8, the at least one electromagnetic shielding peripheral wall 522, together with at least a portion of the housing peripheral wall 110, forms an electromagnetic shielding enclosure structure surrounding at least a portion of the additional electronic unit 400. More specifically, the housing peripheral wall 110 can provide a certain electromagnetic shielding effect for the additional electronic unit 400. This allows for full-dimensional electromagnetic interference shielding of the additional electronic unit 400 with saved materials and reduced components, and further promotes the structural compactness of the electrical device 10. In some examples, the bottom edge of the second portion 520 of the electromagnetic interference isolation bracket 500 can abut against the bottom wall 120 of the housing 100 or against the mounting structure 160 (e.g., ...) provided on the bottom wall 120. Figure 4 As shown), at least a portion of the housing peripheral wall 110, the housing bottom wall 120 and / or at least a portion of the mounting structure 160 together with the second portion 520 of the electromagnetic interference isolation bracket 500 form an electromagnetic shielding enclosure structure that fully surrounds the additional electronic unit 400, thereby further ensuring effective electromagnetic interference shielding of the additional electronic unit 400.

[0068] According to some embodiments, the electrical device 10 may further include conductive adhesive disposed between the second portion 520 of the electromagnetic interference isolation bracket 500 and the housing 100, for example, conductive adhesive disposed between the bottom edge of the second portion 520 and the bottom wall 120 or mounting structure 160 of the housing 100. The conductive adhesive can improve the electromagnetic interference shielding effect on the additional electronic unit 400. Additionally, the conductive adhesive also helps to position the electromagnetic interference isolation bracket 500 relative to the housing 100.

[0069] According to some embodiments, such as Figure 5-6As shown, the electromagnetic interference isolation bracket 500 is a single piece. This allows for simplified assembly of the electrical device 10, thereby reducing assembly costs and improving assembly efficiency. More specifically, the electromagnetic interference isolation bracket 500 is a component formed independently of the housing 100, which can be fixed to the housing 100, for example, by fasteners such as screws.

[0070] According to some embodiments, such as Figure 2-4 As shown in Figure 8, the mounting space of the housing 100 may further include a third receiving portion 150, and the electrical device 10 may further include an additional high-voltage electronic unit 600 disposed in the third receiving portion 150. The electromagnetic interference isolation bracket 500 may also be configured to isolate the third receiving portion 150 from the second receiving portion 140. This further ensures effective electromagnetic interference isolation between different electronic units with a compact structure and a reduced number of components. According to some embodiments, the additional high-voltage electronic unit 600 includes a busbar.

[0071] According to some embodiments, such as Figure 2-6 As shown in Figure 8, the electromagnetic interference isolation bracket 500 may include a third portion 530 extending laterally to the first portion 510. The third portion 530 is disposed between the third receiving portion 150 and the first receiving portion 130 to isolate the third receiving portion 150 from the first receiving portion 130. This allows for effective electromagnetic interference isolation between different electronic units with a simple structure.

[0072] According to some embodiments, the electromagnetic interference isolation bracket 500 can be configured to adapt to the outer contour or overall structure of the various electronic units within the mounting space of the housing 100. In some embodiments, such as Figure 5 Schematably, the top wall 521 of the second portion 520 of the electromagnetic interference isolation bracket 500 may extend parallel to the main extension surface of the first portion 510. Exemplarily, the top wall 521 of the second portion 520 may be located in the same plane as the main extension surface of the first portion 510 or in planes that intersect each other to fully utilize the mounting space within the housing 100. In some embodiments, the electromagnetic shielding peripheral wall 522 of the second portion 520 extends perpendicular to the top wall 521. According to some embodiments, the peripheral wall 522 of the second portion 520 of the electromagnetic interference isolation bracket 500 separates the second receiving portion 140 from the remainder of the mounting space. In some embodiments, the third portion 530 of the electromagnetic interference isolation bracket 500 extends perpendicular to the main extension surface of the first portion 510. According to some embodiments, the third portion 530 of the electromagnetic interference isolation bracket 500 is configured to separate the first receiving portion 130 and the third receiving portion 150 of the mounting space.

[0073] According to some embodiments, such as Figure 1As shown, the housing 100 of the electrical device 10 also includes a cover 170, which is configured to close the opening of the housing 100 and thus close the mounting space of the housing 100.

[0074] According to some embodiments, the electrical device 10 is an inverter.

[0075] Another aspect of this disclosure proposes an electric drive assembly system that includes the electrical device 10 according to any one of the above embodiments, and thus has corresponding technical effects and advantages.

[0076] Another aspect of this disclosure proposes a vehicle comprising the electric drive powertrain system described above. The vehicle may 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 electric vehicle (REV), or a fuel cell electric vehicle (FCEV). The vehicle may also be a hydrogen fuel cell vehicle.

[0077] The exemplary embodiments of the electrical device 10, electric drive assembly system and vehicle proposed in this invention have been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention without exceeding the protection scope of this invention.
