[0002] Electrical device, electric drive assembly system and vehicle

[0003] Technical Field

[0004] The present disclosure relates to an electrical device, which for example is an inverter for a vehicle. The present disclosure further relates to an electric drive assembly system comprising the electrical device, and a vehicle comprising the electric drive assembly system.

[0005] Background Art

[0006] Known electrical devices such as inverters for vehicles comprise a housing and different electrical components arranged in the housing. Electromagnetic isolation is needed between certain different electrical components, e.g. between a low-voltage electrical component and a high-voltage electrical component, to avoid electromagnetic interference between the different electrical components. It is known in the prior art for an electromagnetic interference isolating wall to be provided integrally with a housing, e.g. an electromagnetic interference isolating wall that extends into the housing from a bottom wall or side wall of the housing. The configuration of an integral electromagnetic interference isolating wall increases the complexity of the housing structure, and accordingly has high design and manufacturing costs, while having poor versatility and low cost effectiveness. In addition, in order to ensure the proper installation of electrical components inside the housing, especially when the installation of an electrical component involves horizontal shifting such as shifting parallel to the bottom wall - for example, when an electrical component needs to be installed through a hole in a housing side wall so that a portion of the electrical component is located inside the housing and another portion of the electrical component is located outside the housing - it must be ensured that, while being provided with an integral electromagnetic interference isolating wall, the housing still retains enough installation allowance to allow the shifting of electrical components during iinstallation, so as to ensure that the installation of electrical components is feasible. As a result, the overall size of the housing will be too large, with an excessive amount of idle space created within the housing, making it impossible to realize an electrical device with a compact overall structure. This limits the usability of the electrical device in environments where space is limited.

[0007] Thus, there is a need for a completely new solution to solve at least one of the abovementioned technical problems and achieve other technical effects.

[0008] Summary of the Invention

[0009] According to one aspect, the present disclosure proposes an electrical device. According to an exemplary embodiment, the electrical device comprises:

[0010] a housing, comprising a housing peripheral wall, a bottom wall, and an installation space surrounded by the housing peripheral wall and the bottom wall, the installation space comprising a first accommodating part and a second accommodating part;

[0011] a high-voltage electronic unit and a low-voltage electronic unit, arranged in the first accommodating part;

[0012] an additional electronic unit, at least partly arranged in the second accommodating part;

[0013] an electromagnetic interference isolating support comprising a first portion, the first portion being arranged in the first accommodating part and located between the high-voltage electronic unit and the low-voltage electronic unit so as to isolate the high-voltage electronic unit and the low- voltage electronic unit from each other;

[0014] wherein the electromagnetic interference isolating support further comprises a second portion, the second portion being configured to at least partly surround the additional electronic unit so as to form electromagnetic shielding for the additional electronic unit.

[0015] Thus, in the electrical device proposed in the present disclosure, the electromagnetic interference isolating support not only ensures isolation, in particular electromagnetic interference isolation, between the high-voltageelectronic unit and the low-voltage electronic unit, but also realizes electromagnetic shielding of the additional electronic unit. Thus, in the electrical device proposed in the present disclosure, there is no need to provide various integral electromagnetic interference isolating walls on the housing to realize electromagnetic interference shielding of multiple different electronic units. This simplifies the structure of the housing, and its design and manufacture, thus increasing cost effectiveness. In addition, since the installation space of the housing no longer contains electromagnetic interference isolating walls provided integrally with the housing, the interference presented to the installation of certain electronic units by electromagnetic interference isolating walls is correspondingly eliminated, thus removing the need to reserve installation allowance, ensuring effective utilization of the installation space of the housing, and thus realizing an electrical device which is structurally compact overall. More specifically, the electrical device of the present disclosure allows the electromagnetic interference isolating support to be installed after first installing the electronic units in place in the corresponding accommodating parts of the housing.

[0016] According to different embodiments, the electrical device proposed in the present disclosure may comprise one or more of the following developments.

[0017] According to some embodiments, the additional electronic unit is arranged close to the housing peripheral wall, and has an interface extending through the housing peripheral wall. The electrical device of the present disclosure allows convenient installation, via a compact structure, of the electronic unit extending through the housing peripheral wall, thereby guaranteeing the required properties of the electrical device.

[0018] According to some embodiments, the second portion comprises a top wall and at least one electromagnetic shielding peripheral wall extending transversely with respect to the top wall, the at least one electromagnetic shielding peripheral wall being configured to at least partly surround the additional electronic unit. Thus, in the electrical device of the present disclosure, the second portion of the electromagnetic interference isolating support can form multi-sided electromagnetic shielding around the additional electronic unit, to ensure thenormal operation and performance of the additional electronic unit. According to some embodiments, the at least one electromagnetic shielding peripheral wall together with at least a portion of the housing peripheral wall form an electromagnetic shielding surrounding structure around 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; this not only allows the additional electronic unit to be shielded from electromagnetic interference in all dimensions while saving material with a reduced number of components, but also further promotes structural compactness of the electrical device.

[0019] According to some embodiments, the electrical device further comprises electrically conductive adhesive provided between the second portion and the housing. The electrically conductive adhesive can improve the effectiveness of electromagnetic interference shielding of the additional electronic unit. Additionally, the electrically conductive adhesive also helps to locate the electromagnetic interference isolating support in relation to the housing.

[0020] According to some embodiments, the housing does not comprise an electromagnetic shielding wall, extending upwards from the bottom wall, for the additional electronic unit. It is thus ensured that the installation space of the housing does not contain a structure that might obstruct the installation of the electronic units.

[0021] According to some embodiments, the additional electronic unit comprises an EMC filter plate, the EMC (Electro Magnetic Compatibility) filter plate being arranged in the second accommodating part. This allows a good electromagnetic interference shielding result to be achieved for the EMC filter plate.

[0022] According to some embodiments, the electromagnetic interference isolating support is a single piece. This allows assembly of the electrical device to be simplified, and thus reduces assembly costs while increasing assembly efficiency.

[0023] According to some embodiments, the low- voltage electronic unit is a control unit, and the high-voltage electronic unit comprises a power component.

[0024] According to some embodiments, the installation space further comprises athird accommodating part, the electrical device comprises an additional high-voltage electronic unit arranged in the third accommodating part, and the electromagnetic interference isolating support is further configured to isolate the third accommodating part and the second accommodating part from each other. This further ensures effective electromagnetic interference isolation between different electronic units, via a compact structure with a reduced number of components.

[0025] According to some embodiments, the electromagnetic interference isolating support further comprises a third portion extending transversely with respect to the first portion, the third portion being arranged between the third accommodating part and the first accommodating part, so as to isolate the third accommodating part and the first accommodating part from each other. This allows effective electromagnetic interference isolation between different electronic units, via a simple structure.

[0026] According to some embodiments, the electrical device is an inverter.

[0027] Another aspect of the present disclosure proposes an electric drive assembly system, which comprises the electrical device according to any one of the embodiments above, and thus has corresponding technical effects and advantages.

[0028] Another aspect of the present disclosure proposes a vehicle, comprising the electric drive assembly system as described above.

[0060] Detailed Description of the Invention

[0061] An electrical device 10, an electric drive assembly system and a vehicle according to embodiments of the present disclosure are described in detail below with reference to the drawings. In order to make the objectives, technical solutions and advantages of the present practical disclosure clearer, the technical solutions in embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure; obviously, the embodiments described are some, not all, of the embodiments of the present disclosure.

[0062] Thus, the detailed description below of embodiments of the present disclosure provided in conjunction with the drawings is not intended to limit the claimed scope of the present disclosure, and merely shows selected embodiments of the present disclosure. All other embodiments obtained by those skilled in the art on the basis of the embodiments in the present disclosure without inventive effort are included in the scope of protection of the present disclosure.

Throughout this description, the terms "comprising", "having", etc. are used herein to specify the existence of the mentioned feature, number, step, operation, element, component or combination thereof, without ruling out the existence or addition of one or more other features, numbers, steps, operations, elements, components or combinations thereof.

[0064] In addition, even though terms including ordinal numbers such as "first" and "second" can be used to describe various components, these components are not restricted by these terms, which are merely used to distinguish one element fromanother. For example, without departing from the scope of the present 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.

[0065] In the description of the present invention, it should be understood that an orientation or position relationship indicated by a term such as "up", "down", "left", "right", "inside" or "outside" is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship of usual placement of the disclosed product when in use, or the orientation or position relationship commonly understood by those skilled in the art, and is merely intended to facilitate and simplify the description of the present disclosure, without indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so must not be construed as limiting the present disclosure.

[0066] The present disclosure proposes an electrical device 10. As shown in Figs. 1 - 4 and 8, according to exemplary embodiments, the electrical device 10 comprises a housing 100. As shown in Figs. 1 and 4, the housing 100 may comprise a bottom wall 120 and a housing peripheral wall 110; for example, the housing peripheral wall 110 extends transversely with respect to (i.e. not parallel to, including perpendicular to) the bottom wall 120. The housing 100 comprises an installation space at least partly surrounded by the housing peripheral wall 110 and the bottom wall 120. The installation space may comprise different accommodating parts, and more specifically, comprises at least a first accommodating part 130 and a second accommodating part 140. For example, different electrical components or electronic units may be respectively accommodated in different accommodating parts.

[0067] As shown in Figs. 2 - 3 and 7 - 8, according to exemplary embodiments, the electrical device 10 may comprise different electronic units located in the installation space of the housing 100, and comprises an electromagnetic interference isolating support 500. The electromagnetic interference isolating support 500 may be configured to realize electromagnetic interference isolation between different electronic units, so as to ensure the operating performance of theelectronic units.

[0068] According to an embodiment, as shown in Figs. 2 - 3 and 7 - 8, the electrical device 10 may comprise a high-voltage electronic unit 300 and a low-voltage electronic unit 200, and the electromagnetic interference isolating support 500 may comprise a first portion 510. The first portion 510 is configured to be located between the high-voltage electronic unit 300 and the low-voltage electronic unit 200, so as to isolate the high-voltage electronic unit 300 and the low-voltage electronic unit 200 from each other. According to an exemplary embodiment, the high-voltage electronic unit 300 and the low-voltage electronic unit 200 are both arranged in the first accommodating part 130 of the installation space. More specifically, the first portion 510 of the electromagnetic interference isolating support 500 is also located in the first accommodating part 130. According to an exemplary embodiment, the low- voltage electronic unit 200 is a control unit, for example a circuit board comprising various control elements and circuits. Additionally or alternatively, the high-voltage electronic unit 300 comprises a power component, e.g. various power transistors. According to an exemplary embodiment, as shown in Figs. 7 - 8, within the first accommodating part 130, the high-voltage electronic unit 300 and the low-voltage electronic unit 200 may be stacked in a vertical direction perpendicular to the bottom wall 120, with the first portion 510 of the electromagnetic interference isolating support 500 located between the high-voltage electronic unit 300 and the low-voltage electronic unit 200; more specifically, the high-voltage electronic unit 300 is arranged closer to the bottom wall 120 than the low- voltage electronic unit 200. In some embodiments, the bottom wall 120 of the housing 100 partially defines the first accommodating part 130. According to some embodiments, as shown in Figs. 2 -3 and 7, the electrical device 10 may further comprise an additional electronic unit 400, and the electromagnetic interference isolating support 500 may be further configured to realize electromagnetic interference shielding of the additional electronic unit 400. In some embodiments, the additional electronic unit 400 is at least partly arranged in the second accommodating part 140 of the installation space of the housing 100, and the electromagnetic interference isolating support500 may comprise a second portion 520. The second portion 520 is configured to at least partly surround the additional electronic unit 400 so as to form electromagnetic shielding for the additional electronic unit 400, thereby ensuring that the additional electronic unit 400 will not suffer electromagnetic interference from the other electronic units. In some embodiments, the second portion 520 is at least partly or completely arranged in the second accommodating part 140. In some embodiments, the bottom wall 120 of the housing 100 partially defines the second accommodating part 140.

[0069] Thus, in the electrical device 10 proposed in the present disclosure, the electromagnetic interference isolating support 500 not only ensures isolation, in particular electromagnetic interference isolation, between the high-voltage electronic unit 300 and the low-voltage electronic unit 200, but also realizes electromagnetic shielding of the additional electronic unit 400. Thus, in the electrical device 10 proposed in the present disclosure, there is no need to provide various integral electromagnetic interference isolating walls on the housing 100 to realize electromagnetic interference shielding of multiple different electronic units. This simplifies the structure of the housing 100, and its design and manufacture, thus increasing cost effectiveness. In addition, since the installation space of the housing 100 no longer contains electromagnetic interference isolating walls provided integrally with the housing 100, the interference presented to the installation of certain electronic units by electromagnetic interference isolating walls is correspondingly eliminated, thus removing the need to reserve installation allowance, ensuring effective utilization of the installation space of the housing 100, and thus realizing an electrical device 10 which is structurally compact overall. More specifically, the electrical device 10 of the present disclosure allows the electromagnetic interference isolating support 500 to be installed after first installing the electronic units in place in the corresponding accommodating parts of the housing 100.

[0070] According to some embodiments, the housing 100 does not comprise an electromagnetic shielding wall, extending upwards from the bottom wall 120, for the additional electronic unit 400. It is thus ensured that the installation space ofthe housing 100 does not contain a structure that might obstruct the installation of the electronic units.

[0071] According to some embodiments, as shown in Figs. 1 - 2, the additional electronic unit 400 is arranged close to the housing peripheral wall 110, and has an interface 410 extending through the housing peripheral wall 110. As an example, the interface 410 may be used for electrical or signal connection to another electrical component. More specifically, the interface 410 of the additional electronic unit 400 and a remaining portion of the additional electronic unit 400 are connected together, for example, provided integrally or fitted together. Thus, when being installed, the additional electronic unit 400 must pass through an opening in the housing peripheral wall 110; more specifically, the interface 410 thereof extends through the opening in the housing peripheral wall 110 from the inside of the housing 100 to the outside of the housing 100. Thus, the installation of the additional electronic unit 400 involves shifting parallel to the bottom wall 120. As a result of eliminating an electromagnetic interference isolating wall provided integrally with the housing 100, the electrical device 10 of the present disclosure allows the installation space to include sufficient installation allowance to ensure that the additional electronic unit 400 can be shifted horizontally during installation, and thus allows convenient installation, via a compact structure, of the additional electronic unit 400 extending through the housing peripheral wall 110, thereby guaranteeing the required properties of the electrical device 10. According to some embodiments, the additional electronic unit 400 may comprise an EMC filter plate 420, the EMC filter plate 420 being arranged in the second accommodating part 140. This allows a good electromagnetic interference shielding result to be achieved for the EMC filter plate 420.

[0072] According to some embodiments, as shown in Figs. 2 - 3 and 5 - 8, the second portion 520 of the electromagnetic interference isolating support 500 may comprise a top wall 521 and at least one electromagnetic shielding peripheral wall 522 extending transversely with respect to the top wall 521, the at least one electromagnetic shielding peripheral wall 522 being configured to at least partly surround the additional electronic unit 400. In some embodiments, the number ofelectromagnetic shielding peripheral walls 522 may be determined according to the overall profile of the additional electronic unit 400 and the required installation space, so that the electromagnetic shielding peripheral wall 522 can follow the overall profile of the additional electronic unit 400. This further promotes effective utilization of the installation space in the housing 100 while ensuring electromagnetic interference shielding of the additional electronic unit 400, thus making it easier to achieve overall structural compactness of the electrical device 10. Thus, in the electrical device 10 of the present disclosure, the second portion 520 of the electromagnetic interference isolating support 500 can form a multisided electromagnetic shielding structure around the additional electronic unit 400, to ensure the normal operation and performance of the additional electronic unit 400. According to some embodiments, as shown in Figs. 2 - 3 and 5 - 8, the at least one electromagnetic shielding peripheral wall 522 together with at least a portion of the housing peripheral wall 110 form an electromagnetic shielding surrounding structure around at least a portion of the additional electronic unit 400. More specifically, the housing peripheral wall 110 can provide a certain degree of electromagnetic shielding for the additional electronic unit 400; this not only allows the additional electronic unit 400 to be shielded from electromagnetic interference in all dimensions while saving material with a reduced number of components, but also further promotes structural compactness of the electrical device 10. In some examples, a bottom edge of the second portion 520 of the electromagnetic interference isolating support 500 may abut the bottom wall 120 of the housing 100 or abut an installation structure 160 arranged on the bottom wall 120 (as shown in Fig. 4), so that at least a portion of the housing peripheral wall 110, the housing bottom wall 120 and / or at least a portion of the installation structure 160 together with the second portion 520 of the electromagnetic interference isolating support 500 form an electromagnetic shielding surrounding structure that fully encloses the additional electronic unit 400, thus further ensuring effective electromagnetic interference shielding of the additional electronic unit 400.

[0073] According to some embodiments, the electrical device 10 may furthercomprise electrically conductive adhesive provided between the second portion 520 of the electromagnetic interference isolating support 500 and the housing 100, for example, electrically conductive adhesive provided between the bottom edge of the second portion 520 and the bottom wall 120 of the housing 100 or the installation structure 160. The electrically conductive adhesive can improve the effectiveness of electromagnetic interference shielding of the additional electronic unit 400. Additionally, the electrically conductive adhesive also helps to locate the electromagnetic interference isolating support 500 in relation to the housing 100.

[0074] According to some embodiments, as shown in Figs. 5 - 6, the electromagnetic interference isolating support 500 is a single piece. This allows assembly of the electrical device 10 to be simplified, and thus reduces assembly costs while increasing assembly efficiency. More specifically, the electromagnetic interference isolating support 500 is a component that is formed independently of the housing 100, and can be fixed to the housing 100 by fasteners such as screws, for example.

[0075] According to some embodiments, as shown in Figs.2-4 and 8, the installation space of the housing 100 may further comprise a third accommodating part 150, the electrical device 10 may further comprise an additional high-voltage electronic unit 600 arranged in the third accommodating part 150, and the electromagnetic interference isolating support 500 may be further configured to isolate the third accommodating part 150 and the second accommodating part 140 from each other. This further ensures effective electromagnetic interference isolation between different electronic units, via a compact structure with a reduced number of components. According to some embodiments, the additional high-voltage electronic unit 600 comprises a busbar.

[0076] According to some embodiments, as shown in Figs. 2 - 6 and 8, the electromagnetic interference isolating support 500 may comprise a third portion 530 extending transversely with respect to the first portion 510, the third portion 530 being arranged between the third accommodating part 150 and the first accommodating part 130, so as to isolate the third accommodating part 150 and the first accommodating part 130 from each other. This allows effective electromagnetic interference isolation between different electronic units, via asimple structure.

[0077] According to some embodiments, the electromagnetic interference isolating support 500 may be configured to be adapted to an outer profile or overall structure of the electronic units in the installation space of the housing 100. In some embodiments, as shown schematically in Fig. 5, the top wall 521 of the second portion 520 of the electromagnetic interference isolating support 500 may extend parallel to a main extension face of the first portion 510. As an example, the top wall 521 of the second portion 520 and the main extension face of the first portion 510 may be located on the same plane or on mutually staggered planes, so as to make full and effective use of the installation space in 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 isolating support 500 separates the second accommodating part 140 from a remaining portion of the installation space. In some embodiments, the third portion 530 of the electromagnetic interference isolating support 500 extends perpendicular to the main extension face of the first portion 510. According to some embodiments, the third portion 530 of the electromagnetic interference isolating support 500 is configured to separate the first accommodating part 130 and the third accommodating part 150 of the installation space.

[0078] According to some embodiments, as shown in Fig. 1, the housing 100 of the electrical device 10 further comprises a cover 170, the cover 170 being configured to close an opening of the housing 100, and thus closing the installation space of the housing 100.

[0079] According to some embodiments, the electrical device 10 is an inverter.

[0080] Another aspect of the present disclosure proposes an electric drive assembly system, which comprises the electrical device 10 according to any one of the embodiments above, and thus has corresponding technical effects and advantages.

[0081] Another aspect of the present disclosure proposes a vehicle, comprising the electric drive assembly system as described above. The vehicle may be anelectrified vehicle, such as a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), a range extended EV (REV) or a fuel cell electric vehicle (FCEV). The vehicle may also be a hydrogen-powered vehicle.

[0082] Demonstrative embodiments of the electrical device 10, the electric drive assembly system and the vehicle proposed in the present invention have been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that without departing from the concept of the present invention, various modifications and alterations could be made to the specific embodiments above, and various technical features and structures proposed in the present invention could be combined in various ways, without exceeding the scope of protection of the present invention.
