Description

Technical Field

[0001] This application belongs to the field of electromagnetic shielding technology, specifically relating to an electronic device and a vehicle. Background Technology

[0002] Electromagnetic compatibility (EMC) refers to the ability of electronic components to operate normally without interference from other devices in the same electromagnetic environment, while also not interfering with the normal operation of other devices. To meet the EMC performance requirements of electronic equipment, cables typically require electromagnetic shielding.

[0003] In related technologies, one end of the cable located inside the cavity of the electronic device is connected to a shielded connector. The electromagnetic shielding layer of the cable is electrically connected to the electromagnetic shielding structure of the shielded connector, thereby achieving electromagnetic shielding of the cable. This design means the cable can only be used with a shielded connector, resulting in limited flexibility in the design of connectors and related accessories that are electrically connected to the cable in electronic devices. Utility Model Content

[0004] The purpose of this application is to provide an electronic device and vehicle that can solve the problem of poor design flexibility of connectors and related accessories for electrical connections with cables in related technologies.

[0005] In a first aspect, embodiments of this application provide an electronic device, including:

[0006] A housing, wherein the housing is provided with a first metal part, the first metal part being grounded through an external conductor;

[0007] A cable, the first end of which extends into the inner cavity of the housing;

[0008] A first conductive element is electrically connected to the first metal part. The first conductive element includes a first conductive portion, which is disposed along the circumference of the cable and wraps around at least a portion of the electromagnetic shielding layer at the first end of the cable. The first conductive portion is in contact with at least a portion of the electromagnetic shielding layer so that the first conductive element is electrically connected to the electromagnetic shielding layer.

[0009] Secondly, embodiments of this application also provide a vehicle that includes the electronic equipment described above.

[0010] In this embodiment, the housing is provided with a first metal part. The first conductive element is electrically connected to both the electromagnetic shielding layer at the first end of the cable and the first metal part. In actual use, the first metal part is grounded through an external conductor, thereby grounding the electromagnetic shielding layer of the cable and achieving electromagnetic shielding. It is evident that in the solution adopted in this embodiment, there is no correlation between the electromagnetic shielding of the cable and the connector electrically connected to the cable. Thus, the cable can be used not only with shielded connectors but also with other types of connectors besides shielded connectors. This provides greater flexibility in the design of connectors and related accessories electrically connected to the cable, thereby reducing the design difficulty of the electronic device.

[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0041] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0042] Please refer to Figures 1 to 18 As shown, this application provides an electronic device, including a housing 100, a cable 200, and a first conductive element 300. The electronic device is, for example, a controller, and more specifically, an in-vehicle controller.

[0043] The housing 100 is provided with a first metal part 120, which is used for grounding through an external conductor. Here, "grounding" can mean that the external conductor is connected to the earth, or that the first metal part 120 is electrically connected to a reference potential through the external conductor. When electrically connected to the reference potential, the electromagnetic interference experienced by the cable 200 is reduced, thus achieving theoretical "grounding". Furthermore, the first metal part 120 can be part of the housing 100 or an additional component connected to the housing 100. As a specific embodiment, the housing 100 may include, for example, a connected main body 110 and a first metal part 120. The main body 110 has a second opening, and the first metal part 120 covers the second opening and is connected to the main body 110. The external conductor is, for example, the vehicle body, and the first metal part 120 is electrically connected, for example, to a metal part of the vehicle body to achieve grounding. It should also be noted that the first metal part 120 and the external conductor can be directly electrically connected or indirectly electrically connected through other components.

[0044] The first end of the cable 200 extends into the inner cavity of the housing 100. The first conductive element 300 is electrically connected to the first metal part 120. The first conductive element 300 includes a first conductive portion 310, which is arranged circumferentially along the cable 200 and wraps at least a portion of the electromagnetic shielding layer 210 at the first end of the cable 200. In other words, the first conductive portion 310 can wrap a portion of the circumferential electromagnetic shielding layer 210 or wrap the entire circumferential electromagnetic shielding layer 210. When the entire circumferential electromagnetic shielding layer 210 is wrapped, the first conductive portion 310 can be wound around the electromagnetic shielding layer 210 once or at least two times. Alternatively, for example, the insulation layer 220 on the outer surface of the first end of the cable 200 can be removed, exposing the electromagnetic shielding layer 210 at the first end of the cable 200, and then the first conductive portion 310 can be wrapped around the outside of the electromagnetic shielding layer 210. Furthermore, when the first metal part 120 is part of the housing 100, the first end of the cable 200 may pass through the first metal part 120 to extend into the inner cavity of the housing 100.

[0045] The first conductive part 310 is attached to at least a portion of the electromagnetic shielding layer 210 so that the first conductive element 300 is electrically connected to the electromagnetic shielding layer 210. That is, the first conductive part 310 is in contact with the electromagnetic shielding layer 210, thereby realizing the electrical connection between the first conductive element 300 and the electromagnetic shielding layer 210. Optionally, the first conductive part 310 may be attached to a portion of the circumferential direction of the electromagnetic shielding layer 210, or it may be attached to the entire circumferential direction of the electromagnetic shielding layer 210. The first conductive part 310 may be attached to only a portion of the electromagnetic shielding layer 210, or it may be attached to the entire electromagnetic shielding layer 210.

[0046] In this embodiment, the housing 100 is provided with a first metal part 120. The first conductive element 300 is electrically connected to the electromagnetic shielding layer 210 at the first end of the cable 200 and the first metal part 120. In actual use, the first metal part 120 is grounded through an external conductor, which can ground the electromagnetic shielding layer 210 of the cable 200, thereby achieving electromagnetic shielding of the cable 200. It can be seen that in the solution adopted in this embodiment, there is no correlation between the electromagnetic shielding of the cable 200 and the connector electrically connected to the cable 200. Thus, the cable 200 can be used not only with shielded connectors but also with other types of connectors besides shielded connectors. This provides greater flexibility in the design of connectors and related accessories electrically connected to the cable 200, thereby reducing the design difficulty of the electronic device.

[0047] In another embodiment, reference Figure 3 and Figure 4As shown, the housing 100 is further provided with a second metal part 130, which is located in the inner cavity of the housing 100 and is disposed on the side of the first metal part 120 facing the inner cavity of the housing 100, so as to be electrically connected to the first metal part 120. The electronic device also includes a second conductive member 400, which is located in the inner cavity of the housing 100 and between the first conductive part 310 and the second metal part 130. The second conductive member 400 is in contact with both the first conductive part 310 and the second metal part 130 so as to be electrically connected to the first metal part 120. The second conductive member 400 is, for example, conductive foam, and the second conductive member 400 is, for example, a conductive block.

[0048] In this embodiment, the first conductive element 300 is indirectly electrically connected to the first metal part 120 through the second conductive element 400. In this way, the requirements for the first conductive element 300 are lower. The first conductive element 300 only needs to be electrically connected to the electromagnetic shielding layer 210, which simplifies the structure of the first conductive element 300 and reduces its cost.

[0049] Optionally, the first conductive element 300 may include, for example, only the first conductive portion 310 mentioned above, and refer to Figure 4 As shown, when the first conductive portion 310 is in a flattened state, it has a roughly rectangular sheet-like structure. This shape is relatively regular, which makes the processing of the first conductive component 300 easier. Furthermore, in this case, the number of turns of the first conductive portion 310 around the electromagnetic shielding layer 210 can be adjusted, for example, by adjusting the length of the first conductive portion 310.

[0050] Optionally, the second metal part 130 and the first metal part 120 may be an integral structure, for example, with a portion of the first metal part 120 being folded to form the second metal part 130. This configuration provides a more reliable connection between the first metal part 120 and the second metal part 130, thereby improving the stability of the second metal part 130.

[0051] Furthermore, the first metal part 120 is, for example, part of the housing 100. The first metal part 120 is provided with a through hole. The first end of the cable 200 enters and exits the inner cavity of the housing 100 through the through hole. When the first metal part 120 and the second metal part 130 are in a flattened state, the second metal part 130 overlaps with at least a portion of the through hole. That is, a portion of the first metal part 120 is folded over, forming the second metal part 130 and the through hole. With this arrangement, the forming of the second metal part 130 will not add any additional openings other than the through hole to the first metal part 120, thereby making the first metal part 120 have better strength.

[0052] Of course, in other alternative embodiments, the electronic device may not include the second conductive element 400 and the second metal part 130. In this case, the first conductive element 300 may be directly electrically connected to the first metal part 120, thereby realizing the electrical connection between the two.

[0053] In another embodiment, reference Figures 5 to 7 As shown, the electronic device also includes a fixing member 510, which is, for example, an insulating member. The cable 200 is connected to the first metal part 120 through the fixing member 510. The first conductive member 300 also includes a second conductive part 320. The second conductive part 320 is located on the side of the first metal part 120 away from the inner cavity of the housing 100 and is located between the fixing member 510 and the first metal part 120. The second conductive part 320 is connected to the fixing member 510 and is indirectly fixed to the first metal part 120 through the fixing member 510. The second conductive part 320 is in contact with the first metal part 120 so that the first conductive member 300 is electrically connected to the first metal part 120.

[0054] In practical use, the cable 200 is first connected to the fixing member 510, then the second conductive part 320 is connected to the fixing member 510, and then the fixing member 510 is connected to the first metal part 120. This allows for the simultaneous installation of the fixing member 510, the cable 200, and the second conductive part 320. In other words, with the fixing member 510 connected to the first metal part 120, the second conductive part 320 is simultaneously in contact with the first metal part 120, and the cable 200 is indirectly fixed to the first metal part 120. Therefore, in this embodiment, the installation of the second conductive part 320 and the fixing member 510 can be achieved simultaneously in a single installation, making the assembly of the electronic device more convenient.

[0055] As one specific implementation method, refer to Figure 7 As shown, the first conductive part 310 and the second conductive part 320 are directly connected, and the two are arranged in a roughly T-shape.

[0056] Of course, in other alternative embodiments, there may be no connection between the second conductive part 320 and the fixing member 510. In this case, the second conductive part 320 and the fixing member 510 need to be installed on the first metal part 120 respectively.

[0057] This manual also provides an electromagnetic shielding solution, see reference. Figures 8 to 10As shown, in this scheme, the electronic device includes, for example, a metal part 920 and an intermediate conductive part 910. The metal part 920 is located on the side of the first metal part 120 away from the inner cavity of the housing 100 and is located between the fixing part 510 and the first metal part 120. The metal part 920 is connected to the fixing part 510 and is in contact with the first metal part 120. One end of the intermediate conductive part 910 is electrically connected to the electromagnetic shielding layer 210 of the first end of the cable 200, and the other end of the intermediate conductive part 910 is welded to the metal part 920, thereby realizing the sequential electrical connection of the electromagnetic shielding layer 210, the intermediate conductive part 910, the metal part 920 and the first metal part 120, thereby realizing the electromagnetic shielding of the cable 200. As can be seen, welding is necessary in this solution. However, compared with welding, the solution in this application embodiment where the second conductive part 320 directly contacts the first metal part 120 is simpler to operate and has lower cost. Therefore, the solution in this application embodiment can simplify the manufacturing process of electronic devices and reduce the manufacturing cost of electronic devices.

[0058] It should be noted that the intermediate conductive element 910 can be a structure independent of the electromagnetic shielding layer 210 of the cable 200, or it can be part of the electromagnetic shielding layer 210 of the cable 200. In other words, a part of the electromagnetic shielding layer 210 of the cable 200 can be directly used as the intermediate conductive element 910.

[0059] Of course, the metal part 920 can be omitted, and the intermediate conductive part 910 can be directly welded to the first metal part 120 to achieve sequential electrical connection of the electromagnetic shielding layer 210, the intermediate conductive part 910 and the first metal part 120. However, in this case, welding operation is still required. Therefore, compared with this solution, the solution adopted in this application embodiment is also simpler to operate and has a lower cost.

[0060] In a further embodiment, the second conductive part 320 is, for example, bonded to the fastener 510. This arrangement simplifies the connection between the second conductive part 320 and the fastener 510, making the assembly of the electronic device more convenient. Furthermore, this design does not damage the structure of either the second conductive part 320 or the fastener 510, thus extending the service life of both.

[0061] In other alternative embodiments, the second conductive part 320 may also be detachably connected to the fastener 510 by means of bolts or screws.

[0062] In another embodiment, reference Figure 7 and Figure 11As shown, the electronic device also includes a fixing member 510. The cable 200 is connected to the first metal part 120 through the fixing member 510. The first conductive member 300 is located in the inner cavity of the housing 100. The first conductive member 300 also includes a second conductive part 320, which is attached to the side of the first metal part 120 facing the inner cavity of the housing 100, so that the first conductive member 300 is electrically connected to the first metal part 120, and the second conductive part 320 is fixed to the first metal part 120. With this configuration, the first conductive member 300 is located in the inner cavity of the housing 100, so that the first conductive member 300 will not interfere with the housing 100, thereby helping to extend the service life of the first conductive member 300.

[0063] In practical use, first connect the cable 200 to the fixing member 510, then connect the fixing member 510 to the first metal part 120, then attach the second conductive part 320 to the side of the first metal part 120 facing the inner cavity of the housing 100, and connect the second conductive part 320 to the first metal part 120 to complete the installation of the fixing member 510, the cable 200 and the second conductive part 320.

[0064] Optionally, refer to Figure 7 As shown, in this embodiment, the first conductive part 310 and the second conductive part 320 are, for example, directly connected and, for example, are both arranged in a roughly T-shape.

[0065] Optionally, the first conductive part 310 is bonded to the first metal part 120, for example, by conductive adhesive, so that the first conductive member 300 is attached to the first metal part 120, while the second conductive part 320 is fixed to the first metal part 120.

[0066] In one alternative embodiment, when the second conductive part 320 is connected to the fixing member 510, the second conductive part 320 may also be located outside the housing 100, depending on the installation position of the fixing member 510, for example when the fixing member 510 is located outside the housing 100. In this case, the second conductive part 320 may contact the side of the first metal part 120 away from the inner cavity of the housing 100 for electrical connection.

[0067] In another embodiment, the first conductive element 300 is a flexible element. With this configuration, the first conductive element 300 is easy to deform, so that the first conductive part 310 of the first conductive element 300 can be wrapped around the outside of the electromagnetic shielding layer 210 more conveniently. Moreover, since the first conductive element 300 is easy to deform, the shape of the first conductive element 300 can be flexibly adjusted, thereby making the arrangement of the first conductive element 300 more flexible.

[0068] Furthermore, if the first conductive member 300 is a flexible member, the second conductive part 320 may be attached to the fixing member 510, so that there is a large contact area between the second conductive part 320 and the fixing member 510, thereby reducing the deformation of the second conductive part 320.

[0069] In one specific implementation, the first conductive element 300 may be, for example, conductive cloth, metal sheet, conductive rubber, conductive sponge, or conductive double-sided tape. More specifically, the metal sheet may be, for example, copper foil, and the conductive cloth may include, for example, a fiber cloth layer and a metal layer, the metal layer being, for example, a gold layer or a nickel layer. In actual processing, for example, the fiber cloth is used as a substrate, and the metal layer is electroplated onto the fiber cloth to obtain the conductive cloth.

[0070] In other alternative embodiments, the first conductive element 300 may also be a rigid element.

[0071] In another embodiment, there are at least two cables 200 arranged side by side, with each cable 200 corresponding to a first conductive part 310. The electromagnetic shielding layer 210 at the first end of each cable 200 is wrapped by the corresponding first conductive part 310.

[0072] In an optional embodiment, the electromagnetic shielding layer 210 of at least two cables 200 may also be wrapped by the same first conductive part 310. Compared with the previous scheme in which cables 200 and first conductive parts 310 correspond one-to-one, the scheme adopted in this embodiment involves fewer first conductive parts 310, thereby reducing the processing difficulty of the first conductive part 300. Furthermore, the scheme adopted in this embodiment involves fewer wrapping times when wrapping each cable 200, thus making the assembly of electronic devices more convenient.

[0073] In one optional embodiment, based on the first conductive element 300 being a flexible element, the number of cables 200 is, for example, at least two, with each cable 200 arranged side by side, and the electromagnetic shielding layer 210 of at least two cables 200 being wrapped by the same first conductive part 310, so as to simplify the assembly process of electronic devices while ensuring that the arrangement of the first conductive element 300 is relatively flexible.

[0074] In another embodiment, reference Figure 1 As shown, the electronic device also includes a fixing member 510. A cable 200 passes through and connects to the fixing member 510. The fixing member 510 is located outside the housing 100. The fixing member 510 has a snap-fit ​​portion 520 that passes through and engages with the first metal part 120. This design allows the fixing member 510 to be installed onto the first metal part 120 without the need for tools, making installation of the fixing member 510 more convenient.

[0075] In addition, when the fastener 510 is located outside the housing 100, the second conductive part 320 mentioned above is located outside the housing 100 for example, so as to be connected to the fastener 510.

[0076] In another embodiment, the fastener 510 is detachably connected to the first metal part 120 via a threaded connector. The threaded connection offers better reliability, thereby ensuring a more stable connection between the fastener 510 and the first metal part 120.

[0077] In one alternative embodiment, reference is made to... Figure 17 and Figure 18 As shown, the fixing member 510 is provided with a snap-fit ​​portion 520, and the fixing member 510 is detachably connected to the first metal part 120 via a threaded connector. In this embodiment, the snap-fit ​​portion 520 engages with the first metal part 120, allowing for convenient and quick positioning of the fixing member 510. After the position of the fixing member 510 is determined, the threaded connector connects the fixing member 510 to the first metal part 120, ensuring the connection strength between the fixing member 510 and the first metal part 120.

[0078] In another embodiment, reference Figures 12 to 14 As shown, the electronic device also includes a circuit board 610, an electromagnetic shielding cover 620, a first electrical connector 710, and a second electrical connector 720. The electromagnetic shielding cover 620 is electrically connected to the ground wire of the circuit board 610, and the electromagnetic shielding cover 620 and the circuit board 610 together form an electromagnetic shielding space 630. The first electrical connector 710 is electrically connected to the first end of the cable 200, and the second electrical connector 720 is electrically connected to the circuit board 610. Both the first electrical connector 710 and the second electrical connector 720 are located within the electromagnetic shielding space 630, and are electrically connected. This arrangement, with both the first electrical connector 710 and the second electrical connector 720 located within the electromagnetic shielding space 630, achieves electromagnetic shielding for both connectors, thereby improving the EMC performance of the electronic device.

[0079] Furthermore, a portion of the core wire 230 at the first end of the cable 200 is exposed to facilitate electrical connection with the first electrical connector 710. This exposed portion of the core wire 230 is also located in the electromagnetic shielding space 630 to further improve the EMC performance of the electronic device.

[0080] In other alternative embodiments, the electronic device may also exclude the electromagnetic shielding cover 620.

[0081] In a further embodiment, the electronic device further includes a third conductive element 800, which is made of, for example, conductive foam. The third conductive element 800 is disposed between the electromagnetic shielding cover 620 and the first metal part 120, and both the electromagnetic shielding cover 620 and the first metal part 120 are in contact with the third conductive element 800. In other words, the third conductive element 800 is in contact with and electrically connected to both the electromagnetic shielding cover 620 and the first metal part 120. With this configuration, the third conductive element 800 can electromagnetically shield the gap between the electromagnetic shielding cover 620 and the first metal part 120, thereby improving the EMC performance of the electronic device.

[0082] In other alternative embodiments, the electronic device may also exclude the third conductive element 800.

[0083] In a further embodiment, the number of cables 200 is at least two, and the number of first electrical connectors 710 and second electrical connectors 720 is also at least two. Each first electrical connector 710 is electrically connected to a corresponding cable 200, and the first electrical connectors 710 and second electrical connectors 720 correspond one-to-one. Each first electrical connector 710 is also electrically connected to a corresponding second electrical connector 720, and at least two first electrical connectors 710 and at least two second electrical connectors 720 are disposed in the same electromagnetic shielding space 630. This arrangement reduces the number of electromagnetic shielding covers 620, thereby saving costs. Furthermore, with the reduction in the number of electromagnetic shielding covers 620, the electronic device is smaller in size, and the manufacturing difficulty of the electronic device is lower. Moreover, due to the reduction in the number of electromagnetic shielding covers 620, the housing 100 can accommodate more first electrical connectors 710 and second electrical connectors 720, thereby enabling the electronic device to receive more signals. For example, each second electrical connector 720 can transmit more video signals to the circuit board 610 of the electronic device.

[0084] In other optional embodiments, the first electrical connector 710 and the second electrical connector 720 may each have a one-to-one correspondence with the electromagnetic shielding space 630, with each first electrical connector 710 and each second electrical connector 720 disposed in the corresponding electromagnetic shielding space 630. In this case, the number of electromagnetic shielding covers 620 is at least two, and each electromagnetic shielding cover 620 corresponds one-to-one with the first electrical connector 710 and the second electrical connector 720. Furthermore, the number of cables 200 is not limited to at least two, but may be one; the number of first electrical connectors 710 and second electrical connectors 720 is not limited to at least two, but may each be one. The specific number of cables 200, first electrical connectors 710, and second electrical connectors 720 is determined according to actual needs.

[0085] In a further embodiment, the electromagnetic shielding cover 620 and the circuit board 610 together form a first opening, which faces the first metal part 120 and allows the first electrical connector 710 to enter and exit the electromagnetic shielding space 630. This arrangement eliminates the need for additional processing of inlets and outlets for the first electrical connector 710 to enter and exit the electromagnetic shielding space 630, thus facilitating the manufacturing of the electronic device. Furthermore, the large area of ​​the first opening ensures smoother entry and exit of the first electrical connector 710.

[0086] Optionally, the third conductive element 800 mentioned above may be arranged circumferentially around the first opening, for example, referencing Figure 16 As shown, in this case, the third conductive element 800 is, for example, roughly U-shaped. With this arrangement, electromagnetic shielding is achieved between the circumference of the first opening and the gap between the first metal part 120, thereby improving the EMC performance of the electronic device. Alternatively, the third conductive element 800 can be disposed between a portion of the circumference of the first opening and the first metal part 120. In this case, the third conductive element 800 is, for example, disposed only along the circumference of the electromagnetic shielding cover 620, and referenced... Figure 12 As shown, in this case, the third conductive element 800 is, for example, roughly inverted U-shaped.

[0087] In other alternative embodiments, the electromagnetic shielding cover 620 may include, for example, a first side plate disposed toward the first metal part 120, and a first side wall provided with a disassembly port, which allows the first electrical connector 710 to enter and exit the electromagnetic shielding space 630, and the shape of the disassembly port may be adapted to, for example, the shape of the first electrical connector 710.

[0088] This application also provides a vehicle that includes the electronic equipment described above. Optionally, the vehicle is, for example, an automobile, and the electronic equipment is, for example, disposed on the vehicle body. In this case, as described above, the external conductor is, for example, the vehicle body, and the first metal part 120 of the electronic equipment is electrically connected to, for example, a metal part of the vehicle body to achieve grounding.

[0089] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
