Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to an electronic device, powertrain, and vehicle. Background Technology

[0002] Electronic devices house electrical connectors within their insulating housings. Each connector comprises an insulating body and electrical connecting elements (such as pins or conductive tabs) mounted on the insulating body. Depending on the application, electrical connectors can be categorized into high-voltage connectors and low-voltage connectors. High-voltage connectors are used to transmit electrical energy, while low-voltage connectors are used to transmit low-voltage signals.

[0003] To prevent electromagnetic interference, electromagnetic shielding structures are incorporated into electronic devices. In related technologies, the electromagnetic shielding structure of electrical connectors is a metal shield that defines a shielded space housing the electrical connector. One end of the electrical connector extends out of the shielded space and is electrically connected to circuit components within the insulating housing. However, the electromagnetic shielding effect of the metal shield is relatively poor, and the electrical connector is still susceptible to interference, thus affecting its performance. Utility Model Content

[0004] This application provides an electronic device, powertrain, and vehicle to solve the problem of poor electromagnetic shielding effect of electrical connectors.

[0005] In a first aspect, this application provides an electronic device, comprising:

[0006] An insulating housing having a cavity in which circuit components are disposed;

[0007] An electrical connector, comprising an insulating body and at least one electrical connector, wherein the insulating body is connected to the insulating housing, the electrical connector is located within the cavity, one end of the electrical connector is connected to the insulating body, and the other end is used for electrical connection with the circuit components within the cavity;

[0008] An electromagnetic shielding assembly includes a first metal layer, an insulating layer, and a second metal layer. The first metal layer is disposed on at least a portion of the inner surface of the cavity and is used for grounding. The insulating layer is disposed on the outer peripheral surface of at least one of the electrical connectors. The second metal layer is disposed on the outer side of the insulating layer. A conductive portion is provided between the first metal layer and the second metal layer, and the conductive portion electrically connects the first metal layer and the second metal layer.

[0009] In one possible implementation, the conductive portion is a conductive protrusion disposed on one of the first metal layer and the second metal layer, and the conductive protrusion abuts against the other of the first metal layer and the second metal layer.

[0010] In one possible implementation, the conductive portion is a conductive sheet disposed on one of the first metal layer and the second metal layer, and the conductive sheet abuts against the other of the first metal layer and the second metal layer.

[0011] In one possible implementation, the second metal layer has two oppositely disposed connecting sides, one of the two connecting sides having at least one connecting portion, and the other of the two connecting sides having at least one connecting mating portion, the connecting portion being used to connect to the connecting mating portion to connect the second metal layer to the outside of the insulating layer.

[0012] In one possible implementation, one of the connecting portion and the connecting mating portion is a connector head, and the other is a connecting hole, wherein the connector head is inserted into the connecting hole.

[0013] In one possible implementation, the side of the second metal layer facing the insulating layer has a plurality of protrusions;

[0014] And / or, at least one grounding connection is provided on the first metal layer, the grounding connection extending to the outside of the insulating housing and abutting against the outer surface of the insulating housing.

[0015] In one possible implementation, the insulating layer is a heat-shrinkable sleeve fitted over the electrical connector;

[0016] Alternatively, the insulating layer may be a plastic layer formed on the electrical connector.

[0017] In one possible implementation, at least one of the first metal layer and the second metal layer is an aluminum layer, an aluminum alloy layer, or a silver layer.

[0018] Secondly, this application provides a powertrain including an electric motor and a motor controller electrically connected to the electric motor, wherein the motor controller is an electronic device as described above.

[0020] The electronic devices, powertrains, and vehicles provided in this application improve the overall electromagnetic shielding effect of the electronic devices by setting a first metal layer on the inner surface of the cavity. By setting a second metal layer outside the insulating layer of the electrical connectors, the electromagnetic shielding effect of the electrical connectors is specifically improved. Furthermore, the first metal layer is grounded, and the conductive part is electrically connected to the first and second metal layers. This allows the induced charge generated in the second metal layer during the electromagnetic shielding process to be released through the first metal layer, and the induced charge generated in the first metal layer during the electromagnetic shielding process to be directly released. This helps prevent the induced charge from forming an interfering electric field on the first and second metal layers, thereby improving the electromagnetic shielding effect of the electromagnetic shielding assembly.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0042] In existing technologies, electronic devices are typically equipped with electrical connectors. An electrical connector mainly consists of an insulating body and electrical connectors mounted on the insulating body. These electrical connectors can be pins, conductive plates, etc. Depending on the application, electrical connectors can be divided into two categories: high-voltage connectors and low-voltage connectors. High-voltage connectors are primarily responsible for transmitting electrical energy, while low-voltage connectors can be used for transmitting low-voltage signals.

[0043] To avoid electromagnetic interference, electronic devices typically incorporate electromagnetic shielding structures. In related technologies, the electromagnetic shielding structure for electrical connectors is a metal shield, with the connector located within the shield and one end extending out and electrically connected to circuit components within an insulating housing. However, this type of metal shield offers poor shielding effectiveness, thus affecting the performance of the electrical connector.

[0044] Based on the above-mentioned technical problems, this application provides an electronic device, a powertrain, and a vehicle. The structure of the electronic device is described below with reference to the accompanying drawings.

[0045] Reference Figure 1 and Figure 2As shown in the illustration, the electronic device in this embodiment includes an insulating housing 100, an electrical connector 200, and an electromagnetic shielding assembly 300. The insulating housing 100 has a cavity 130, within which circuit components are disposed. The electrical connector 200 includes an insulating body 210 and at least one electrical connector 220. The insulating body 210 is connected to the insulating housing 100, and the electrical connector 220 is located within the cavity 130. One end of the electrical connector 220 is connected to the insulating body 210, and the other end is used for electrical connection with the circuit components within the cavity 130.

[0046] The electromagnetic shielding assembly 300 includes a first metal layer 310, an insulating layer 320, and a second metal layer 330. The first metal layer 310 is disposed on at least a portion of the inner surface of the cavity 130 and is used for grounding. The insulating layer 320 is disposed on the outer peripheral surface of at least one electrical connector 220, and the second metal layer 330 is disposed on the outer side of the insulating layer 320. A conductive portion 311 is provided between the first metal layer 310 and the second metal layer 330, and the conductive portion 311 electrically connects the first metal layer 310 and the second metal layer 330.

[0047] In this embodiment of the electronic device, the first metal layer 310 is provided on the inner surface of the cavity 130, which helps to improve the overall electromagnetic shielding effect of the electronic device. The second metal layer 330 is provided outside the insulating layer 320 of the electrical connector 220, which helps to specifically improve the electromagnetic shielding effect of the electrical connector 220. Furthermore, the first metal layer 310 is grounded, and the conductive part 311 is electrically connected to the first metal layer 310 and the second metal layer 330, so that the induced charge generated by the second metal layer 330 during the electromagnetic shielding process is released through the first metal layer 310, and the induced charge generated by the first metal layer 310 during the electromagnetic shielding process is directly released, which helps to prevent the induced charge from forming an interfering electric field on the first metal layer 310 and the second metal layer 330, thereby improving the electromagnetic shielding effect of the electromagnetic shielding assembly.

[0048] The electronic device in this embodiment can be a product with an electrical connector 200. For example, the electronic device can be a controller, including a motor controller, a power controller, a vehicle air conditioning controller, etc. The electrical connector 200 can be a high-voltage connector or a low-voltage connector.

[0049] When the electrical connector 200 is a high-voltage connector, the electrical connector 220 can be in the form of a sheet, such as a copper busbar. When the electrical connector 200 is a low-voltage connector, the electrical connector 220 can be a PIN (Pin Header Pin). Circuit components can be, for example, circuit boards (e.g., PCBs), power chips, functional modules, etc. Other components not mentioned in the electrical connector 200, and their connection relationships with the electrical connector 220, can be found in existing technologies and will not be elaborated upon here.

[0050] In one possible implementation, such as Figure 1 As shown in the illustration, the insulating housing 100 in this embodiment includes a body 110 having a cavity 130 and a cover 120 disposed on the top of the body 110. The top of the cavity 130 is open, and the cover 120 is used to seal the openness. The insulating body 210 of the electrical connector 200 is specifically connected to the cover 120. Of course, the position of the electrical connector 200 can also be adjusted according to usage requirements, and the electrical connector 200 can be connected to the body 110.

[0051] The insulating shell 100 is made of plastic to facilitate the weight reduction of electronic devices. The first metal layer 310 can be disposed on the entire inner surface of the cavity 130 (that is, the inner surfaces of the body 110 and the cover 120). Figure 2 Only the first metal layer 310 disposed in the main body 110 is shown in the diagram. At this time, not only can the first metal layer 310 be protected by the insulating shell 100, but the electromagnetic shielding area of ​​the first metal layer 310 is also larger, and the electromagnetic shielding effect is better.

[0052] In specific implementation, the shape of the first metal layer 310 can be adapted to the shape of the cavity 130. The first metal layer 310 can be made of aluminum, aluminum alloy, or silver. Here, aluminum, aluminum alloy, and silver layers are all readily available and facilitate the adaptation of the first metal layer 310 to the inner surface shape of the cavity 130. Of course, the first metal layer 310 can also be made of other metal materials, as long as the electromagnetic shielding requirements are met. Furthermore, it is also feasible to set the first metal layer 310 only on the body 110 or the cover 120. The specific arrangement can be determined according to the usage requirements.

[0053] In one possible implementation, at least one grounding connection portion 3101 is provided on the first metal layer 310, the grounding connection portion 3101 extending to the outside of the insulating housing 100 and abutting against the outer surface of the insulating housing 100. The provision of the grounding connection portion 3101 here facilitates the grounding of the first metal layer 310.

[0054] As an example of the structure of the grounding connection part 3101, such as Figure 1 As shown, the grounding connection portion 3101 is a flange provided on the first metal layer 310, which extends to the outside of the insulating housing 100 and abuts against the outer surface of the insulating housing 100. Here, a through hole 121 is provided on the insulating housing 100 for the flange to pass through.

[0055] Here, the flange is directly formed by the first metal layer 310 located inside the cover 120, which helps ensure the reliability of the connection between the flange and the first metal layer 310. After passing through the through hole 121 of the insulating housing 100, the flange abuts against the outer surface of the insulating housing 100, which facilitates the connection between the flange and an external grounding body (such as the cylinder body or equipment grounding plane). This ensures that the induced charge on the first metal layer 310 is released to the external grounding body through the flange, thereby avoiding the formation of new electromagnetic interference caused by the accumulation of induced charge and affecting the electromagnetic shielding effect of the first metal layer 310 and the second metal layer 330. Of course, the grounding connection part 3101 can also be grounded in other ways, as long as the usage requirements are met.

[0056] Still refer to Figure 1 As shown, the cover 120 has a plurality of spaced-apart through holes 121, and a plurality of spaced-apart flanges. The flanges pass through the through holes 121 on the cover 120 and abut against the outer surface of the cover 120. When the insulating housing 100 is connected to an external grounding body, such as a cylinder, the flanges are sandwiched between the cover 120 and the cylinder. The cylinder is made of metal, and the flanges abut against the cylinder, so that the first metal layer 310 is electrically connected to the cylinder, achieving the purpose of grounding. This allows the induced charge on the first metal layer 310 to be released to the cylinder through the flanges.

[0057] In one possible implementation, the conductive portion 311 is a conductive protrusion disposed on one of the first metal layer 310 and the second metal layer 330, and the conductive protrusion abuts against the other of the first metal layer 310 and the second metal layer 330. The conductive protrusion here has a simple structure and is easy to process and form.

[0058] The conductive protrusions in this embodiment achieve electrical connection between the first metal layer 310 and the second metal layer 330 through direct contact. During assembly, the electrical connection between the first metal layer 310 and the second metal layer 330 can be completed simply by contacting the metal layer with the conductive protrusions with another metal layer, which helps to improve production efficiency.

[0059] In one possible implementation, such as Figure 2 and Figure 3 As shown, an electrical connector 220 is disposed near one side of the cavity 130, and a conductive protrusion is formed on the first metal layer 310, which protrudes toward the closer electrical connector 220 and abuts against the second metal layer 330 on the electrical connector 220.

[0060] At this time, the second metal layer 330, which is electrically connected to the conductive protrusion, can release the induced charge generated by itself to the first metal layer 310. The first metal layer 310 is grounded. The first metal layer 310 releases the induced charge generated by itself and the induced charge from the second metal layer 330 to the external ground body, which helps to avoid the electric field generated by the induced charge from forming an interference source, thereby helping to ensure the electromagnetic shielding effect of the first metal layer 310 and the second metal layer 330.

[0061] It should be noted that forming conductive bumps on the second metal layer 330 is also feasible. Furthermore, the number of conductive bumps, besides being... Figure 3 In addition to the one shown, two can also be set according to the arrangement requirements within the cavity 130. In this case, the first metal layer 310 is electrically connected to each of the second metal layers 330 through two conductive protrusions.

[0062] In another possible implementation, such as Figure 4 As shown, the conductive part 311 is a conductive sheet, which is disposed on one of the first metal layer 310 and the second metal layer 330, and abuts against the other of the first metal layer 310 and the second metal layer 330. Here, the conductive sheet itself has a certain degree of flexibility and elasticity, which helps to ensure the abutment effect when it abuts against the corresponding metal layer. Even if the gap between the electrical connector 220 and the first metal layer 310 is slightly large, electrical connection can still be achieved through the conductive sheet.

[0063] In practical implementation, for example, the conductive sheet includes a first part and a second part connected together, making the conductive sheet "L"-shaped. The first part is electrically connected to the first metal layer 310, and the second part is electrically connected to the second metal layer 330. In this case, the conductive sheet has a simple structure, is easy to arrange and implement, and has a good electrical connection effect. Of course, the shape and specifications of the conductive sheet can be determined according to the usage requirements.

[0064] In one possible implementation, an exemplary structure of the electrical connector 200 is as follows: Figures 5 to 7 As shown, the insulating body 210 is block-shaped and is detachably connected to the insulating housing 100. For example, multiple through holes are provided around the insulating body 210 at intervals. Bolts pass through the corresponding through holes and are screwed to the cover 120, thereby installing the insulating body 210 on the insulating housing 100.

[0065] Here, the insulating body 210 is detachably connected to the insulating housing 100, facilitating the installation and removal of the electrical connector 200, thereby simplifying its replacement and maintenance. The insulating body 210 is detachably connected to the insulating housing 100 via bolts, offering the advantage of easy installation and removal. Of course, the insulating body 210 can also be connected to the insulating housing 100 using other connection methods, as long as the installation and removal requirements on the insulating housing 100 are met.

[0066] Electrical connector 220 can be Figure 7 The two shown can be added or removed according to usage requirements. Both electrical connectors 220 are long strips and are spaced apart on the insulating body 210.

[0067] In one possible implementation, the insulating layer 320 is a heat-shrinkable sleeve fitted over the electrical connector 220. The heat-shrinkable sleeve has the characteristic of shrinking upon heating. After being fitted over the electrical connector 220, the heat-shrinkable sleeve can be heated to tightly adhere to the outer circumferential surface of the electrical connector 220, achieving a tight fit. This arrangement not only helps ensure the reliability of the insulation between the electrical connector 220 and the second metal layer 330, but also facilitates the arrangement and installation of the electrical connector 220.

[0068] In another possible implementation, the insulating layer 320 is a plastic layer molded onto the electrical connector 220. This plastic layer can be molded onto the electrical connector 220 by means of extrusion, injection molding, etc., so that the insulating layer 320 is tightly connected to the electrical connector 220, which helps to ensure the insulation reliability of the insulating layer 320.

[0069] like Figure 5 and Figure 6 As shown, the insulating layer 320 extends from one end of the electrical connector 220 connected to the insulating body 210 to the other end. To ensure effective electrical connection between the electrical connector 220 and the circuit components, the end of the electrical connector 220 furthest from the insulating body 210 is spaced apart from the insulating layer 320. To ensure effective insulation between the electrical connector 220 and the second metal layer 330, the length of the insulating layer 320 is greater than or equal to the length of the second metal layer 330.

[0070] In this embodiment, the second metal layer 330 in the connected state is as follows: Figure 8 As shown, the second metal layer 330 in the unfolded state is as follows Figure 9 As shown, the second metal layer 330 is sheet-like in its unfolded state. To better wrap around the insulating layer 320, the second metal layer 330 is rolled up around the insulating layer 320, forming three creases on the second metal layer 330 (shown by dashed lines in the figure).

[0071] The second metal layer 330 has two opposing connecting sides 331. One of the connecting sides 331 has at least one connecting portion 3313, and the other connecting side 331 has at least one connecting mating portion 3314. The connecting portion 3313 is used to connect with the connecting mating portion 3314 to connect the second metal layer 330 to the outside of the insulating layer 320. The connection between the connecting portion 3313 and the connecting mating portion 3314 facilitates the placement of the second metal layer 330 outside the insulating layer 320.

[0072] In one possible implementation, one of the connecting portion 3313 and the connecting mating portion 3314 is a connector head, and the other is a connecting hole, with the connector head inserted into the connecting hole. Here, the second metal layer 330 can be disposed on the electrical connector 220 simply by inserting the connector head into the corresponding connecting hole, eliminating the need for external connection structures and offering the advantage of easy connection, thereby improving assembly efficiency.

[0073] For ease of distinction in description, such as Figure 9 As shown, the connecting side 331 with connectors is referred to as the first connecting side 3311, and the connecting side 331 with connecting holes is referred to as the second connecting side 3312. Two connectors are provided on the first connecting side 3311, and two connecting holes are provided on the second connecting side 3312. After the connectors are inserted into their corresponding connecting holes, the first connecting side 3311 and the second connecting side 3312 are connected.

[0074] For example, the connector can be hooked onto the connection hole by folding it over, resulting in a stable and reliable connection. Furthermore, the connector-to-connection-hole insertion method also facilitates the removal of the second metal layer 330.

[0075] Understandably, the number of connectors and connecting holes can be adjusted according to usage requirements. In addition, besides the connector and connecting hole plug-in connection scheme, the connector 3313 and the connecting mating part 3314 can also be snapped into the connecting hole, as long as the connection requirements between the two connecting sides 331 are met.

[0076] In addition, such as Figure 8 and Figure 9 As shown, a connecting piece 3315 can also be provided between the two second metal layers 330, connecting the two second metal layers 330 together. This improves the molding and assembly efficiency of the second metal layers 330. In the connected state, the connecting piece 3315 specifically abuts against the insulating body 210. Of course, a solution without the connecting piece 3315 is also feasible.

[0077] In one possible implementation, such as Figure 9 and Figure 10 As shown, the second metal layer 330 has a plurality of protrusions 332 on the side facing the insulating layer 320. By providing a plurality of protrusions 332, the friction between the insulating layer 320 and the second metal layer 330 can be increased, thereby improving the reliability of the connection of the second metal layer 330 to the outside of the insulating layer 320.

[0078] In practice, the protrusion 332 can be formed on the second metal layer 330 by stamping. The shape, specifications, and density of the protrusion 332 can be determined according to the application requirements.

[0079] The second metal layer 330 in this embodiment can be made of aluminum, aluminum alloy, or silver. Aluminum, aluminum alloy, and silver layers are all readily available and easy to wrap around the insulating layer 320. Of course, the second metal layer 330 can also be made of other metal materials, as long as they meet the requirements for electromagnetic shielding.

[0080] In this embodiment, the electronic device, through the combination of insulating layer 320 and second metal layer 330, effectively improves the electromagnetic shielding effect on the electrical connector 220. Compared to the traditional metal casing solution, this saves space and eliminates the cost of complex molds, thereby reducing production costs. Furthermore, the use of insulating layer 320 and second metal layer 330 does not require modification of the electrical connector 200's structure, allowing it to be applied to electrical connectors 220 of different specifications, demonstrating good applicability.

[0081] The powertrain provided in this application includes a motor and a motor controller electrically connected to the motor, wherein the motor controller includes the electronic devices in any of the above embodiments.

[0082] In this system, the motor and the motor controller work together. The motor controller controls the operating status of the motor, and the feedback signal from the motor affects the control commands that the motor controller gives to the motor.

[0083] The motor controller includes a power module (the aforementioned circuit components), a control main board, and a drive circuit, all housed within an insulating housing 100. The electrical connector 220 in the motor controller can be electrically connected to the power module to transmit the AC power output from the power module to the motor.

[0084] Here, the cooperation of the first metal layer 310, the second metal layer 330, and the conductive part 311 in the motor controller helps to improve the electromagnetic shielding effect of the motor controller as a whole and its power connector 200, thereby preventing electromagnetic interference from affecting the performance of the motor controller, making the signal transmission between the motor controller and the motor more stable, and thus improving the stability of the powertrain.

[0085] The vehicle provided in this application embodiment includes a vehicle body 110 and the powertrain described above disposed on the vehicle body 110.

[0086] The vehicle here features a powertrain as described above. The motor controller of the powertrain has good electromagnetic interference resistance, which facilitates the motor's response to control commands and thus improves the vehicle's driving comfort.

[0087] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0088] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
