Description

Technical Field

[0001] This application relates to the field of conductive structure technology of electrical components, specifically to an electronic device, and also to a vehicle. Background Technology

[0002] Electronic devices, such as controllers, often use pins (also known as PINs) to make conductive connections between their circuit boards and power modules. One end of the pin is soldered to the circuit board, and the other end is soldered to the power module.

[0003] However, during vibration testing of automotive controllers, the circuit board modes resonate with the vibration excitation, resulting in excessive circuit board amplitude. This leads to greater stress on the pins, and stress concentration is more likely to occur at the root of the pins encapsulated by the power module. In severe cases, pin breakage and failure may occur, affecting the product qualification rate. Utility Model Content

[0026] The embodiments of this application will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments. It should be understood that, in the actual implementation of any embodiment, changes may occur from one embodiment to another to achieve specific objectives. Furthermore, it is also understood that, although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content of this application, some design, manufacturing, or production modifications based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient content of this application.

[0027] like Figures 1-7 As shown, the electronic device provided in this application embodiment includes a first electrical component 1; a second electrical component 5; multiple pins 4, one end of each pin 4 being electrically connected to the first electrical component 1 and the other end being electrically connected to the second electrical component 5; and a fixing member 3 for fixing at least two of the multiple pins 4, the fixing member having a fixing structure for fixing at least two pins 4.

[0028] In the electronic device provided in this application embodiment, the first electrical component 1 and the second electrical component 5 are electrically connected by multiple pins 4. At least two of the multiple pins 4 are fixed by the fixing structure of the fixing member 3, thereby fixing the at least two pins 4 together and making the at least two pins 4 form a whole. This can improve the overall strength of the at least two pins 4, thereby reducing the stress concentration generated by the pins 4, reducing the risk of pin 4 breakage failure, and improving the product qualification rate of the electronic device.

[0029] In some embodiments, the fixing member 3 is an insulating block, and the fixing structure is a fixing hole formed in the insulating block. The insulating block can be a rubber block, which has a certain hardness and can provide good fixing strength for at least two pins 4. The size of the rubber block is sufficient to cover at least two pins 4, and its position can be adjusted according to the overall layout of the electronic device. Generally, it is placed between the first electrical component 1 and the second electrical component 5, near the end of the pin 4 where stress concentration is more likely to occur. For example, when the first electrical component 1 is a circuit board and the second electrical component 5 is a power device, it is more effective to place the rubber block near the soldering position of the pin 4 to the circuit board or near the root of the pin 4 encased in plastic by the power module. If space does not permit, it can be adjusted appropriately. The rubber block is lightweight and small in size, which adds little to the overall weight of the electronic device, thus achieving the purpose of weight reduction and cost reduction.

[0030] The insulating block can also be a plastic block, with the pins 4 glued to the fixing holes using adhesive. In other embodiments, the insulating block can be injection molded onto at least two pins 4, saving assembly operations.

[0031] The fastener 3 can also be a fastener clip, which can hold at least two pins 4 in place by means of a slot, thereby binding at least two pins 4 together, improving the fastening strength of the pins 4, reducing stress concentration on the pins 4, reducing the risk of pin 4 breakage and failure, and improving the product qualification rate of electronic devices.

[0032] In some embodiments, the fixing hole includes at least two pinholes, and at least two pins 4 are correspondingly inserted into the pinholes. By inserting the pins 4 one-to-one along their length into the pinholes, at least two pins 4 are fixed in the insulating block, which facilitates operation and ensures fixing strength. It is understood that the insulating block may also have only one pinhole, through which all pins 4 are inserted, which can also achieve the goal of fixing at least two pins 4 to the insulating block.

[0033] In some embodiments, at least two pins 4 include at least one bent pin, the bent pin including a first pin segment, an inclined pin segment and a second pin segment connected in sequence, the first pin segment and the second pin segment being arranged parallel to each other, and the inclined pin segment being arranged at an angle relative to the first pin segment; at least two pin holes include bent pin holes that mate with the bent pin, the bent pin holes including a first hole segment for inserting the first pin segment and gap-fitting the first pin segment; and a second hole segment for inserting the inclined pin segment and the second pin segment and positioning them with the inclined pin segment.

[0034] During assembly, the first segment of the bent needle is inserted into the second segment of the bent needle hole; the inclined segment and the second segment of the bent needle are inserted into the second segment of the bent needle hole and positioned with the inclined segment. This arrangement allows for a limiting fit along the length of needle 4 through at least one bent needle and the bent needle hole, thereby improving the fixing strength of needle 4.

[0035] At least two pins 4 may include at least one upright pin; at least two pin holes include upright pin holes that are clearance-fitted with the upright pins; the structure is simple and can save costs.

[0036] In some embodiments, the bent pin further includes a third pin segment connected to the second pin segment, the third pin segment being perpendicular to the second pin segment; wherein the first pin segment is electrically connected to the first electrical component 1, and the third pin segment is electrically connected to the second electrical component 5. Thus, the bent pin is generally L-shaped, facilitating connection between the first electrical component 1 and the second electrical component 5, and saving installation space. The upright pin can also be L-shaped and fixedly installed in conjunction with the bent pin.

[0037] In some embodiments, the multiple pins 4 are divided into three phases, and the fixing member 3 fixes two or three pins 4 of the single-phase pins 4 of the multiple pins 4. By using the fixing member 3 to bind two or three pins of one phase of the multiple pins 4, the pins 4 in each phase are closer together, which facilitates layout. For example, two or three pins of each phase are bound together with a rubber block, and the resonance deformation of the circuit board is changed from being borne by one pin to being borne by two or three pins, which greatly reduces the stress concentration between the pins and the root of the second electrical component 5, such as the power module.

[0038] In some embodiments, the electronic device further includes an intermediate element 2 located between the first electrical element 1 and the second electrical element 5, such as... Figures 1-4 As shown, the intermediate element 2 has multiple through holes for the pins 4 to pass through; there are multiple fixing members 3, which are arranged one by one with the through holes, and at least some of the fixing members 3 are located in the through holes and the gap between them and the hole wall is filled with connecting glue g.

[0039] The fastener 3 can be partially located inside the through hole and partially located outside the through hole; alternatively, it can be entirely located inside the through hole. For example, as shown... Figures 5-7 As shown, all the fasteners 3 are located inside the through holes, which avoids the fasteners 3 occupying extra space, facilitates the layout, and the connection between the fasteners 3 and the intermediate element 2 is relatively stable.

[0040] If space permits, when there is a relatively thick intermediate element 2 between the first electrical component 1 and the second electrical component 5, rubber can be poured into the gap between the through hole of the intermediate element 2 and the fixing member 3, such as a rubber block, to form a connecting adhesive g. This connects the fixing member 3, which has the pin 4, and the intermediate element 2 into an integrated structure with better overall strength, further improving the support strength of the pin 4. In this way, on the one hand, it can provide support for the first electrical component 1, improve the stiffness and modality of the first electrical component 1, and thus reduce the deformation caused by resonance. On the other hand, it can block the influence of the modal deformation of the first electrical component 1 on the pin 4, reduce the root stress of the connection between the pin 4 and the second electrical component 5, and reduce the occurrence of fracture failure.

[0041] Moreover, compared to directly inserting the pin 4 into the through hole, the distance between the pin 4 and the wall of the through hole is smaller; the gap between the fixing member 3 and the wall of the through hole in this embodiment is smaller, making it easier to inject adhesive without it flowing out of the through hole.

[0042] In some embodiments, the through hole includes a straight section 21 and a tapered section 22. The straight section 21 is disposed near the second electrical component 5, and the tapered section 22 tapes from one end near the straight section 21 to the end away from the straight section 21. The straight section 21 allows the fastener 3 to enter, and the end of the tapered section 22 away from the straight section 21 can restrict the fastener 3 from passing through and protrude towards the first electrical component 1.

[0043] like Figure 7 As shown, the straight cylindrical section 21 of the through hole has a larger opening, while the tapered section 22 has a smaller opening. During assembly, the fastener 3 enters the through hole through the opening of the straight cylindrical section 21. The straight cylindrical section 21 has a larger cross-section than the tapered section 22, facilitating the installation of the fastener 3. Simultaneously, the tapered section 22 provides unilateral restraint for the fastener 3, preventing it from protruding through the opening of the tapered section 22, thus facilitating proper installation and reducing glue leakage during glue injection, facilitating the filling of the connecting glue g. Furthermore, the protruding design of the tapered section 22 increases the filling volume of the connecting glue g, improving the connection strength between the intermediate element 2 and the fastener 3, thereby enhancing the stability of the pin 4. In some embodiments, the intermediate element 2 is a copper busbar coated with plastic or a heat sink 6. When the first electrical component 1 is a circuit board and the second electrical component 5 is a power module, the intermediate element 2 is located between the power module and the circuit board. The intermediate element 2 can be a heat sink 6, such as an aluminum plate. The intermediate element 2 can also be a copper busbar coated with plastic to insulate the copper busbar, which enables communication connections between various components of the controller. The fastener 3 can be a rubber block.

[0044] By injecting adhesive to fix the rubber block to the aluminum plate or copper busbar plastic-coated part, on the one hand, it provides support for the circuit board and provides circuit board modes; on the other hand, it blocks the pulling of the circuit board mode deformation on pin 4, further reducing the stress concentration at the root of pin 4 which is plastic-coated by the power module, and reducing the risk of pin 4 breakage.

[0045] In some embodiments, the first electrical component 1 and the second electrical component 5 are arranged in parallel, with one end of the multiple pins 4 electrically connected to the first electrical component 1 perpendicular to the first electrical component 1, and the other end electrically connected to the second electrical component 5 parallel to the first electrical component 1. For example... Figure 5 As shown, the first electrical component 1 and the second electrical component 5 are arranged parallel to each other vertically, with the pin 4 bent, forming an L-shape to facilitate the connection of the pin 4 to the two electrical components. It is understood that, depending on the actual application, the first electrical component 1 and the second electrical component 5 can also be arranged at an angle or vertically.

[0046] In some embodiments, in a direction perpendicular to the first electrical element 1, the pin 4 includes at least one of a straight segment, a bent segment, and an arc segment. For example, as Figure 8 As shown, the portion of pin 4 perpendicular to the first electrical component 1 includes an arc segment and a straight segment. The arc segment allows pin 4 to undergo slight deformation, creating an assembly allowance and reducing stress concentration. For example, as... Figure 6 As shown, the portion of pin 4 on the left side perpendicular to the first electrical component 1 includes a straight segment, resulting in a simple structure and ease of manufacturing. For example, as... Figure 6 As shown, the portion of the pin 4 on the right side perpendicular to the first electrical component 1 includes a straight section and a bent section, which can improve the strength of the pin 4 and facilitate the installation and positioning of the pin 4.

[0047] In some embodiments, the electronic device is a controller; the first electrical component 1 is a circuit board; and the second electrical component 5 is a power module, such as... Figure 5 and Figure 8 As shown, pin 4 is connected to the power module at the end (i.e., the root) and the power module is plastically encased in plastic. The controller can be a controller for a transmission or a controller for other structures such as a motor.

[0048] The power module can be an IGBT (Insulated Gate Bipolar Transistor) module or a TPAK (Power Semiconductor Device) module, and it is usually soldered to the circuit board with pins to achieve communication.

[0049] The controller PIN structure design disclosed in this embodiment changes the deformation of the circuit board from one PIN to at least two PINs, which greatly reduces the stress concentration at the root of the PIN encapsulated by the power module and reduces the risk of PIN breakage failure.

[0050] Optionally, the power module can be attached to a heat sink 6 inside the controller housing. The heat sink 6 can be a water-cooled plate or a metal plate. The heat sink 6 is used to dissipate heat from the power device, ensuring the reliability of the power device's operation. The power module can also be attached to a support plate inside the controller housing.
