Description

Technical Field

[0001] This application relates to the technical field of electrical components, and more particularly to an electronic device, an electric drive system, and a vehicle. Background Technology

[0002] To save manufacturing costs, there is an increasing trend in vehicles to use insulating shells made of plastic or other materials instead of metal shells for power and electronic control products such as on-board chargers, DC-DC converters, and motor controllers.

[0003] When the metal casing is replaced with an insulating casing such as plastic, the original grounding line inside the casing used for grounding electronic components (such as circuit boards) will no longer be usable, and a new grounding line needs to be designed.

[0004] In related technologies, in order to adapt to changes in housing material, a new grounding mechanism for grounding electronic components has been designed on the insulating housing, but the structure of the grounding mechanism is relatively complex. Utility Model Content

[0005] Based on this, this application provides an electronic device, an electric drive system, and a vehicle to solve the problem of the complex structure of the grounding mechanism in related technologies.

[0006] In a first aspect, embodiments of this application provide an electronic device, comprising:

[0007] An insulating housing having a mounting cavity and a clearance through hole communicating with the mounting cavity;

[0008] An electronic component, disposed within the mounting cavity, has a grounding terminal;

[0009] The connector is movably disposed within the clearance through hole along the first direction, and the connector is opposite to the grounding terminal; one end of the connector is located inside the mounting cavity and makes conductive contact with the grounding terminal, and the other end is located outside the mounting cavity for making conductive contact with the grounding element.

[0010] In some embodiments, the connector is threaded into the clearance through hole.

[0011] In some embodiments, the connector includes:

[0012] The connecting part is threaded into the clearance through hole, with one end located in the mounting cavity and in conductive contact with the grounding terminal.

[0013] The abutment portion is fixedly connected to the other end of the connecting portion, located outside the mounting cavity, and protruding outside the clearance through hole, for conductive contact with the grounding element.

[0014] In some embodiments, the electronic device further includes:

[0015] A shielding shell covers the insulating shell and serves as the grounding element. At least a portion of the shielding shell is located between the abutting portion and the insulating shell. The abutting portion presses against the shielding shell and makes conductive contact with it.

[0016] In some embodiments, the electronic device further includes:

[0017] A sealing ring is fitted over the connecting part and makes sealing contact with both the connecting part and the inner wall of the clearance through hole.

[0018] In some embodiments, the clearance through hole includes a first hole segment and a second hole segment that are connected.

[0019] The connecting part includes a screw section and a smooth section. The screw section is threadedly connected to the first hole section, and the smooth section is located in the second hole section and between the abutting part and the connecting part. The smooth section is connected to the abutting part and the screw section.

[0020] The sealing ring is fitted outside the smooth rod section and is in sealing contact with both the smooth rod section and the inner wall of the second hole section.

[0021] In some embodiments, the electronic device further includes:

[0022] An elastic element is conductively connected to the grounding terminal and located between the connector and the grounding terminal; along the first direction, the elastic element is deformable, and the connector is in conductive contact with the elastic element so that the connector is in conductive contact with the grounding terminal.

[0023] In some embodiments, the insulating housing is a plastic housing.

[0024] Secondly, embodiments of this application provide an electric drive system, including a motor and the electronic device described in the first aspect, wherein the electronic components of the electronic device are electrically connected to the motor.

[0025] Thirdly, embodiments of this application provide a vehicle including the electronic device described in the first aspect or the electric drive system described in the second aspect.

[0026] This application has at least the following beneficial effects:

[0027] Electronic devices bypass connectors by creating clearance through holes in the insulating housing. One end of the connector is located inside the mounting cavity, making conductive contact with the grounding terminal of the electronic device, while the other end is located outside the mounting cavity, making conductive contact with the grounding element. This design allows the electronic device to be directly grounded via the connector. The structure is simple, the grounding path is short, and the grounding impedance is reduced, thus improving the grounding performance of the electronic device. Furthermore, the connector is movably positioned within the clearance through hole along a first direction, and the connector and the grounding terminal are opposite each other along the first direction. This allows the connector to be fixed in multiple different positions along the first direction, providing a degree of freedom. The position of the connector can be adaptively adjusted according to the different positions of the grounding terminal of the electronic device, ensuring conductive contact between the connector and the grounding terminal. This reduces the accuracy requirements for the installation of the electronic device in the first direction and facilitates the manufacturing of the electronic device. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0037] 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 display 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 display.

[0038] In related technologies, in order to adapt to changes in housing material, a new grounding mechanism for grounding electronic components has been designed on the insulating housing, but the structure of the grounding mechanism is relatively complex.

[0039] Specifically, the related technology discloses a blind-plug grounding clip structure for an electrical cabinet chassis, including a plastic chassis shell, a PCB board, a chassis grounding wire interface post, a grounding conductive clip, an elastic assisting spring, and a fastening nut. The PCB board is installed inside the plastic chassis shell and has a PCB board grounding electrode. The chassis grounding wire interface post is installed in a through hole on the plastic chassis shell. The grounding conductive clip and the elastic assisting spring are both located inside the plastic chassis shell, and one end of each is connected to the end of the chassis grounding wire interface post inside the plastic chassis shell. The other end of the grounding conductive clip is in contact with the PCB board grounding electrode. The elastic assisting spring is fitted to the grounding conductive clip. The fastening nut is located on the outside of the plastic chassis shell and is threaded onto the chassis grounding wire interface post. The chassis grounding wire interface post is fixedly connected to the plastic chassis shell by one end of the grounding conductive clip and the elastic assisting spring from the inside and the fastening nut from the outside.

[0040] The blind-plug grounding clip structure includes multiple components for PCB grounding, such as the chassis grounding interface post, grounding conductive clip, elastic assist spring, and fastening nut. The conductive clip and elastic assist spring are riveted to the side of the grounding interface post inside the plastic chassis. This complex structure is difficult to manufacture. The numerous components also lengthen the grounding path on the PCB, increasing grounding impedance and thus reducing the PCB grounding performance.

[0041] In view of this, the inventors designed an electronic device 100, an electric drive system, and a vehicle. The electronic device 100 avoids the connector 130 by opening a clearance through hole 110b in the insulating housing 110. One end of the connector 130 is located inside the mounting cavity 110a and makes conductive contact with the grounding terminal 121 of the electronic component 120, while the other end is located outside the mounting cavity 110a and makes conductive contact with the grounding element. With this design, the electronic component 120 is directly conductively connected to the grounding element through the connector 130, thereby grounding the electronic component 120. Its structure is simple, the grounding path of the electronic component 120 is short, the grounding impedance is reduced, and the grounding performance of the electronic component 120 is improved.

[0042] The electronic device 100, electric drive system and vehicle provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0043] Appendix Figure 1 In the middle, X is the first direction, such as Figure 1 and Figure 2As shown, the electronic device 100 includes an insulating housing 110, an electronic component 120, and a connector 130. The insulating housing 110 has a mounting cavity 110a and a clearance through hole 110b communicating with the mounting cavity 110a. The electronic component 120 is disposed within the mounting cavity 110a and has a grounding terminal 121. Along a first direction, the connector 130 is movably disposed within the clearance through hole 110b, and the connector 130 is opposite to the grounding terminal 121; one end of the connector 130 is located within the mounting cavity 110a and makes conductive contact with the grounding terminal 121, and the other end is located outside the mounting cavity 110a for making conductive contact with a grounding element.

[0044] The insulating housing 110 is made of insulating material, which electrically isolates the internal electronic components 120 from the external environment, preventing current leakage, short circuits, and electric shock accidents. The insulating housing 110 can be made of plastics such as polyamide, polycarbonate, acrylonitrile-butadiene-styrene copolymer, and polyphenylene sulfide; it can also be made of rubber such as silicone rubber and EPDM rubber; or it can be made of ceramic materials such as alumina ceramic and silicon nitride ceramic. The material is diverse and is not limited in this application.

[0045] Electronic device 100 may be an on-board charger, a DC-DC converter, a motor controller, etc., and is not limited in this application. The mounting cavity 110a of the insulating housing 110 is used to accommodate electronic component 120, which may be a circuit board, an IGBT (Insulated Gate Bipolar Transistor) module, a bus capacitor, etc. The specific components placed in the mounting cavity 110a are related to the specific type of electronic device 100, and are not limited in this application, and are known to those skilled in the art. For example, if electronic device 100 is a motor controller, components such as a circuit board, an IGBT module, a three-phase copper busbar assembly, and a bus capacitor may be placed in the mounting cavity 110a. For example, if electronic device 100 is a DC-DC converter, components such as a circuit board, an inductor coil, a control chip, a capacitor, and a transformer may be placed in the mounting cavity 110a.

[0046] The clearance through-hole 110b connects to the mounting cavity 110a and serves to avoid the connector 130. One end of the connector 130 extends from outside the mounting cavity 110a into the mounting cavity 110a through the clearance through-hole 110b. Some electronic components 120 within the mounting cavity 110a require grounding. These grounded electronic components 120 have a grounding terminal 121, and the connector 130 is in conductive contact with the grounding terminal 121 of the grounded electronic components 120. The grounding terminal 121 is the port of the electronic component 120 for electrical connection to a ground wire. For example, in some embodiments, a circuit board is disposed within the insulating housing 110, and the circuit board has a grounding terminal 121. The connector 130 is in conductive contact with the grounding terminal 121 of the circuit board. The other end of the connector 130 is located outside the mounting cavity 110a and is used for conductive contact with a grounded element. The grounding element can be a ground wire or an element that is electrically connected to a ground wire, such as a shielding shell 140, etc., and is not limited in this application.

[0047] The connector 130 is movably disposed within the clearance through hole 110b along the first direction. This means that the connector 130 can move along the first direction within the clearance through hole 110b, and can be fixed in that position after moving to a certain position. In other words, the connector 130 can be fixed in multiple different positions along the first direction. With this design, the position of the connector 130 can be adaptively adjusted according to the different positions of the grounding terminal 121, facilitating conductive contact between the connector 130 and the grounding terminal 121.

[0048] There are various ways to achieve the active connection, and this application does not limit them. For example, multiple slots are provided at intervals along the first direction on the inner wall of the clearance through hole 110b, and an elastic protrusion is provided on the outside of the connector 130. When force is applied to the connector 130 along the first direction, the protrusion will deform and disengage from the slot, and the elastic member 160 can then move in the first direction. When the protrusion is located in the slot, the protrusion and the slot are engaged, and the connector 130 is fixed. When the protrusion is engaged in different slots, the connector 130 is located at different positions along the first direction. For example, a rubber ring is fixed to the inner wall of the clearance through hole 110b, and the connector 130 is inserted into the rubber ring. The rubber ring is located between the clearance through hole 110b and the connector 130, and the rubber ring abuts against the connector 130. When no force is applied to the connector 130, the connector 130 is fixed under the action of the friction of the rubber ring. When a certain force is applied to the connector 130 in the first direction, the connector 130 can overcome the friction of the rubber ring and move in the first direction.

[0049] The electronic device 100 avoids the connector 130 by opening a clearance through hole 110b in the insulating housing 110. One end of the connector 130 is located inside the mounting cavity 110a and makes conductive contact with the grounding terminal 121 of the electronic component 120, while the other end is located outside the mounting cavity 110a and makes conductive contact with the grounding element. With this design, the electronic component 120 is directly conductively connected to the grounding element through the connector 130, thereby grounding the electronic component 120. Its structure is simple, the grounding path of the electronic component 120 is short, the grounding impedance is reduced, and the grounding performance of the electronic component 120 is improved. In addition, the connector 130 is movably disposed within the clearance through hole 110b along the first direction, and the connector 130 and the grounding terminal 121 are opposite each other along the first direction, so that the connector 130 can be fixed at multiple different positions along the first direction, with a certain degree of freedom. Thus, the position of the connector 130 can be adaptively adjusted according to the different positions of the grounding terminal 121 of the electronic component 120, ensuring that the connector 130 and the grounding terminal 121 are in conductive contact, reducing the installation accuracy requirements of the electronic component 120 in the first direction, and facilitating the processing and manufacturing of the electronic device 100.

[0050] In some embodiments, the connector 130 is threaded into the clearance through hole 110b.

[0051] The inner wall of the clearance through hole 110b is provided with an internal thread, and the peripheral wall of the connector 130 is provided with an external thread. The external thread and the internal thread are threaded together to achieve threaded connection of the connector 130 into the clearance through hole 110b. It should be noted that the clearance through hole 110b is set along a first direction so that the internal thread also extends along the first direction. This allows the connector 130 to move in the first direction when it rotates within the clearance through hole 110b, thereby achieving: the connector 130 is movably disposed within the clearance through hole 110b along the first direction.

[0052] With this design, the position of the connector 130 in the first direction can be adjusted by rotating the connector 130 clockwise or counterclockwise, making the adjustment of the connector 130 more convenient. Since the connector 130 and the clearance through hole 110b are threadedly engaged, the connector 130 can move steplessly in the first direction, that is, move continuously, making the position of the connector 130 more flexible. This facilitates the conductive contact between the connector 130 and the grounding terminal 121 of the electronic component 120, and further reduces the installation accuracy requirements of the electronic component 120 in the first direction.

[0053] It should be noted that the clearance through hole 110b can be pre-drilled, for example, a clearance through hole 110b with internal threads can be pre-drilled on the insulating housing 110, and the connector 130 can be directly screwed into the clearance through hole 110b; or it can be formed simultaneously when the connector 130 is threaded. For example, if the connector 130 is a self-tapping screw, and the clearance through hole 110b is not pre-drilled on the insulating housing 110, the clearance through hole 110b can be formed simultaneously on the insulating housing 110 during the screwing process.

[0054] In some embodiments, the connector 130 includes a connecting portion 131 and an abutting portion 132. The connecting portion 131 is threaded into the clearance through hole 110b, with one end located within the mounting cavity 110a and in conductive contact with the grounding terminal 121. The abutting portion 132 is fixedly connected to the other end of the connecting portion 131, located outside the mounting cavity 110a, and protruding outside the clearance through hole 110b, for conductive contact with the grounding element.

[0055] The connecting portion 131 is cylindrical with external threads on its peripheral wall for threaded connection with the clearance through hole 110b. The end of the connecting portion 131 furthest from the abutment portion 132 is located within the mounting cavity 110a for conductive contact with the grounding terminal 121. The abutment portion 132 protrudes beyond the clearance through hole 110b, meaning its size is larger than the clearance through hole 110b, preventing it from extending into the clearance through hole 110b. This ensures the abutment portion 132 remains outside the mounting cavity 110a, achieving successful conductive contact with the grounding element. This design also limits the connection portion 131's insertion by the abutment portion 132. When the connection portion 131 extends to the point where the abutment portion 132 contacts the insulating housing 110, it cannot be further inserted, preventing excessive insertion and potential damage to the electronic component 120, thus extending the lifespan of the electronic device 100.

[0056] It should be noted that both the connecting part 131 and the abutting part 132 are conductive to ensure that the electronic component 120 can be grounded through the connector 130.

[0057] In some embodiments, the electronic device 100 further includes a shielding shell 140, which covers the insulating shell 110. The shielding shell 140 is a grounding element. At least a portion of the shielding shell 140 is located between the abutment portion 132 and the insulating shell 110. The abutment portion 132 presses against the shielding shell 140 and makes conductive contact with the shielding shell 140.

[0058] In these embodiments, the shielding shell 140 is grounded, and the abutment portion 132 makes conductive contact with the shielding shell 140, thereby grounding the electronic component 120 that is in conductive contact with the connection portion 131. The shielding shell 140 covers the outer surface of the insulating shell 110, which can reduce or eliminate the influence of external electromagnetic interference on the signal of the electronic component 120 in the mounting cavity 110a, and also reduce or eliminate the interference caused by the signal leakage of the electronic component 120 in the mounting cavity 110a. The material of the shielding shell 140 is varied, and can be a metal such as copper or aluminum, which is not limited in this application. At least a portion of the shielding shell 140 is located between the abutment portion 132 and the insulating shell 110. With this design, after tightening the connector 130, the abutment portion 132 of the connector 130 can press the shielding shell 140 into conductive contact with the shielding shell 140, thereby fixing the shielding shell 140 and facilitating its installation.

[0059] In some embodiments, the electronic device 100 further includes a sealing ring 150, which is sleeved on the outside of the connecting portion 131 and makes sealing contact with both the connecting portion 131 and the inner wall of the clearance through hole 110b.

[0060] The sealing ring 150 seals the gap between the connecting part 131 and the clearance through hole 110b, preventing external moisture and other substances from entering the mounting cavity 110a through the gap between the connecting part 131 and the clearance through hole 110b, which helps to ensure the continuous and stable operation of the electronic components 120 in the mounting cavity 110a.

[0061] In some embodiments, the bypass through hole 110b includes a first hole segment 110b1 and a second hole segment 110b2 that are connected; the connecting part 131 includes a screw segment 1311 and a smooth rod segment 1312, the screw segment 1311 is threadedly connected to the first hole segment 110b1, the smooth rod segment 1312 is located in the second hole segment 110b2 and is located between the abutment part 132 and the connecting part 131, and the smooth rod segment 1312 is connected to the abutment part 132 and the screw segment 1311; the sealing ring 150 is sleeved on the smooth rod segment 1312 and is in sealing contact with both the smooth rod segment 1312 and the inner wall of the second hole segment 110b2.

[0062] In other words, the abutment portion 132, the smooth rod section 1312, and the screw section 1311 are arranged sequentially along the first direction. The end of the smooth rod section 1312 near the abutment portion 132 is fixedly connected to the abutment portion 132, and the end near the screw section 1311 is fixedly connected to the screw section 1311. Both the screw section 1311 and the smooth rod section 1312 are cylindrical. The outer peripheral wall of the screw section 1311 is provided with external threads, while the outer peripheral wall of the smooth rod section 1312 is not provided with external threads. The inner peripheral wall of the first hole section 110b1 is provided with internal threads, while the inner peripheral wall of the second hole section 110b2 is not provided with internal threads. The screw section 1311 is threaded into the first hole section 110b1. The sealing ring 150 is sleeved on the outside of the smooth rod section 1312 and located inside the second hole section 110b2. The sealing ring 150 is in sealing contact with both the outer peripheral wall of the smooth rod section 1312 and the inner peripheral wall of the second hole section 110b2, sealing the gap between the smooth rod section 1312 and the second hole section 110b2.

[0063] With this design, the connecting part 131 has external threads only on the side away from the abutment part 132, and no external threads on the side close to the abutment part 132. Similarly, the clearance through hole 110b has internal threads only on the side away from the abutment part 132, and no internal threads on the side close to the abutment part 132. The clearance through hole 110b and the connecting part 131, which are in contact with the sealing ring 150, are not threaded. This facilitates the sealing contact between the sealing ring 150 and the connecting part 131 and the clearance through hole 110b, improving the sealing effect of the sealing ring 150 and preventing damage to the sealing ring 150 from the threads, thus extending the service life of the sealing ring 150.

[0064] In some embodiments, the electronic device 100 further includes an elastic element 160, which is electrically connected to the ground terminal 121 and located between the connector 130 and the ground terminal 121. The elastic element 160 is deformable along a first direction, and the connector 130 is in conductive contact with the elastic element 160 so that the connector 130 is in conductive contact with the ground terminal 121.

[0065] The elastic element 160 is elastic; pressing the elastic element 160 deforms it, and releasing it returns it to its original state. The elastic element 160 is conductive. It can be a metal spring, conductive foam, etc., and is not limited in this application. Furthermore, the structures of metal springs, conductive foam, etc., are diverse and known to those skilled in the art, and will not be described in detail here. The elastic element 160 and the grounding terminal 121 can be electrically connected by welding, screws, or other methods. The elastic element 160 is conductively connected to both the grounding terminal 121 and in conductive contact with the connecting element 130, thereby making the connecting element 130 conductively connected to the grounding terminal 121.

[0066] The design of the elastic element 160 allows the grounding terminal 121 of the electronic device 100 to be kept away from the connector 130. The connector 130 presses against the elastic element 160 instead of the grounding terminal 121. The elastic element 160 is elastic, and when the length of the connector 130 extending into the mounting cavity 110a is too long, the connector 130 can deform to avoid the connector 130, thus preventing the connector 130 from extending too far and damaging the electronic device 120. This helps to ensure the long-term stable operation of the electronic device 100. In the embodiment where the connector 130 and the clearance through hole 110b are threadedly connected, after the connector 130 presses against the elastic member 160, the elastic member 160, being elastic, will exert a force on the connector 130 away from the direction of the elastic member 160, causing the external thread of the connector 130 and the internal thread in the clearance through hole 110b to abut axially. This reduces the risk of the connector 130 rotating uncontrollably and moving in the first direction, and helps to keep the connector 130 in an accurate position in the first direction.

[0067] In some embodiments, the connector 130 is in surface contact with the elastic member 160. Surface contact can reduce contact resistance and ensure the grounding performance of the electronic component 120.

[0068] In some embodiments, the insulating housing 110 is a plastic housing.

[0069] The plastic housing can be made of materials such as polyamide, polycarbonate, acrylonitrile-butadiene-styrene copolymer, and polyphenylene sulfide. Plastic housings have a lower density, better meeting the lightweight requirements of vehicle power and electronic control products. Furthermore, plastics have good plasticity and flowability, allowing for the manufacture of housings with various complex shapes through injection molding, blow molding, compression molding, and other molding processes. They can also be integrated with other components, better meeting the compactness and integration requirements of vehicle power and electronic control products.

[0070] like Figure 2 As shown, in some embodiments, a screw hole 132a is provided on the abutment portion 132. The screw hole 132a allows tools such as sockets and screwdrivers to extend into it. When these tools rotate, they abut against the side wall of the screw hole 132a, pushing the connector 130 to rotate together, thus facilitating the user's rotation of the connector 130. The cross-section of the screw hole 132a can be triangular, quadrilateral, pentagonal, elliptical, etc., and is not limited in this application.
