Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device technology, and in particular to an insulating shell and an electronic controller. Background Technology
[0002] Automobiles often have electronic controllers, which include a housing, a circuit board and several electronic components mounted on the circuit board. The housing includes two shell parts, both of which are insulators. The two shell parts are connected to each other and form a cavity. The circuit board is installed in the cavity.
[0003] In related technologies, the distance between the inner wall of the cavity and the circuit board is small. Static electricity in the vehicle body can enter the housing through the gap between the two shells, which can easily affect the electronic components on the circuit board and cause them to malfunction. Utility Model Content
[0004] Therefore, it is necessary to provide an insulating shell and an electronic controller to address the above problems. The insulating shell can extend the electrostatic creepage path to prevent electrostatic discharge from affecting electronic components on the circuit board, thereby improving the anti-static performance of the electronic controller.
[0005] On the one hand, an insulating shell is provided, comprising:
[0006] The first shell component includes a first substrate and a first connecting portion disposed on the first substrate;
[0007] The second shell assembly includes a second substrate and a second connecting portion disposed on the second substrate. The second substrate is spaced apart from and opposite to the first substrate. The first connecting portion is connected to the second connecting portion. A cavity for accommodating a circuit board is formed between the second substrate and the first substrate.
[0008] The first barrier has a surrounding structure and at least partially protrudes into the cavity. The first barrier is spaced apart on one side of the first connection portion. One end of the first barrier is connected to the first substrate, and the other end extends toward the second substrate and protrudes from the position where the first connection portion and the second connection portion are connected. The interior of the first barrier is used to house the circuit board.
[0009] In one embodiment, a second barrier in a surrounding structure is further included. The second barrier is spaced apart on the side of the first barrier away from the first connection portion. One end of the second barrier is connected to the second substrate, and the other end extends toward the first substrate and partially extends into the interior of the first barrier. There is a gap between the second barrier and the first substrate. The end of the second barrier near the first substrate is used to abut against the circuit board.
[0010] In one embodiment,
[0011] The first shell assembly further includes a plurality of first reinforcing ribs disposed on the opposite side of the first substrate and the second substrate. The first reinforcing ribs protrude from the first substrate, and the plurality of first reinforcing ribs are spaced apart along the first barrier. The opposite ends of the first reinforcing ribs are respectively connected to the first connecting portion and the first barrier.
[0012] And / or, the second shell component further includes a plurality of second reinforcing ribs disposed on the side opposite to the first substrate of the second substrate, the second reinforcing ribs protruding from the second substrate, and the plurality of second reinforcing ribs being spaced apart along the second barrier, the opposite ends of the second reinforcing ribs being connected to the second connecting portion and the second barrier respectively.
[0013] In one embodiment, when the second shell assembly includes a plurality of second reinforcing ribs, the first barrier member is opposite to each of the second reinforcing ribs. The first barrier member includes a barrier body connected to the first substrate and a foolproof protrusion disposed on the end of the barrier body away from the first substrate. The foolproof protrusion protrudes from the barrier body, wherein a portion of the second reinforcing ribs is opposite to the foolproof protrusion, and the remaining portion of the second reinforcing ribs is opposite to the barrier body. The height of the second reinforcing ribs opposite to the foolproof protrusion protruding from the second substrate is less than the height of the second reinforcing ribs directly opposite the barrier body protruding from the second substrate, so that the second reinforcing ribs opposite to the foolproof protrusion can avoid the foolproof protrusion.
[0014] In one embodiment, a connector is further included for connecting the circuit board to the second substrate, the second substrate having a first connection hole, the connector being for passing through the first connection hole and tightening into a hole structure on the circuit board, so that the circuit board abuts against the second barrier.
[0015] In one embodiment, there is a gap between the first barrier and the circuit board.
[0016] In one embodiment, the first connecting portion protrudes from one side of the first substrate near the second substrate, the second connecting portion protrudes from one side of the second substrate near the first substrate, and the height of the first connecting portion protruding from the first substrate is less than the height of the second connecting portion protruding from the second substrate;
[0017] Alternatively, the second connecting portion protrudes from one side of the second substrate near the first substrate, and the first connecting portion is flush with or recessed on the opposite side of the first substrate near the second substrate.
[0018] In one embodiment, a snap-fit assembly is also included, the snap-fit assembly including a snap-fit protrusion and a snap-fit plate that engages with the snap-fit protrusion, one of the snap-fit protrusion and the snap-fit plate being disposed on the first shell body and the other being disposed on the second shell body.
[0019] In one embodiment, a bracket is also included, one end of which is snapped into the first or second shell assembly, and the other end is connected to an external mounting component.
[0020] On the other hand, an electronic controller is also provided, including a circuit board, several electronic components and the aforementioned insulating shell, wherein the electronic components are mounted on the circuit board and the circuit board is mounted in a cavity inside the insulating shell.
[0021] In this type of insulating shell, a first barrier is provided in the cavity. One end of the first barrier is connected to the first substrate, and the other end extends toward the second substrate and protrudes from the position where the first connection part and the second connection part are connected. In this way, when static electricity from outside the insulating shell enters the cavity through the gap between the first connection part and the second connection part, the static electricity must pass through the side of the first barrier part near the first connection part, the side of the first barrier part away from the first substrate, and the side of the first barrier part away from the first connection part before reaching the circuit board. Therefore, the first barrier effectively extends the creepage path of static electricity, preventing external static electricity from affecting the electronic components on the circuit board, thereby protecting the electronic components on the circuit board.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0040] See Figure 1 , Figure 1 This paper shows a schematic diagram of the electronic controller from one angle in some embodiments of this application. Figure 2An exploded view of an electronic controller according to some embodiments is shown. Some embodiments of this application provide an electronic controller used in an automobile, i.e., the electronic controller is installed in an automobile. The electronic controller includes a circuit board 8, several electronic components (not shown), and an insulating housing. The electronic components are all mounted on the circuit board 8, which is installed in a cavity 100 inside the insulating housing.
[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The insulating shell includes a first shell segment 1, a second shell segment 2, and a first barrier element 3, all of which are insulating elements. In this embodiment, the first shell segment 1 is disposed below the second shell segment 2. (See also...) Figure 6 and Figure 7 The first housing component 1 includes a first substrate 11 and a first connecting portion 12 disposed on the first substrate 11, the first connecting portion 12 being disposed around the outer periphery of the first substrate 11. The second housing component 2 includes a second substrate 21 and a second connecting portion 22 disposed on the second substrate 21, the second connecting portion 22 being disposed around the outer periphery of the second substrate 21. The second substrate 21 is spaced apart from and opposite to the first substrate 11. The first connecting portion 12 is connected to the second connecting portion 22. A cavity 100 for accommodating the circuit board 8 is formed between the second substrate 21 and the first substrate 11. The first barrier 3 has a surrounding structure and at least partially protrudes into the cavity 100. The first barrier 3 is spaced apart on one side of the first connecting portion 12. One end of the first barrier 3 is connected to the first substrate 11, and the other end extends toward the second substrate 21 and protrudes from the position where the first connecting portion 12 and the second connecting portion 22 are connected. The interior of the first barrier 3 is used to house the circuit board 8. In this type of insulating shell, a first barrier 3 is provided in the cavity 100. One end of the first barrier 3 is connected to the first substrate 11, and the other end extends toward the second substrate 21 and protrudes from the position where the first connecting part 12 and the second connecting part 22 are connected. In this way, when static electricity from outside the insulating shell enters the cavity 100 through the gap between the first connecting part 12 and the second connecting part 22, the static electricity must travel from the side of the first barrier 3 near the first connecting part 12, through the end of the first barrier 3 away from the first substrate 11, and through the side of the first barrier 3 away from the first connecting part 12 before reaching the circuit board 8. Therefore, the first barrier 3 effectively extends the creepage path of static electricity, preventing external static electricity from affecting the electronic components on the circuit board 8, thereby protecting the electronic components on the circuit board 8.
[0042] In this type of electronic controller, a first barrier 3 is provided inside the cavity 100 of the insulating shell. By blocking the static electricity, the creepage path of the first barrier 3 is effectively extended, preventing the static electricity outside the electronic controller from affecting the electronic components on the circuit board 8, thereby improving the anti-static performance of the electronic controller and making the electronic controller meet industry standards.
[0043] See Figure 4 and Figure 5 To make the internal structure of the insulating shell more compact, the first barrier 3 can be positioned close to the first connecting portion 12, and a portion of the second connecting portion 22 abuts against the side of the first connecting portion 12 facing the cavity 100. A gap exists between the second connecting portion 22 and the first barrier 3 to allow for an assembly gap. The distance between the first barrier 3 and the first connecting portion 12 is the sum of the thickness of the abutting portion of the second connecting portion 22 and the assembly gap between them. The gap between the second connecting portion 22 and the first barrier 3 is 0.2mm-0.3mm, for example, it can be set to 0.2mm, 0.22mm, 0.24mm, 0.26mm, 0.28mm, or 0.3mm. In actual implementation, the thickness of the part of the second connecting part 22 that abuts against the first connecting part 12 can be flexibly adjusted according to the overall size of the insulating shell, thereby flexibly adjusting the distance between the first barrier 3 and the first connecting part 12. The distance between the first barrier 3 and the first connecting part 12 is not specifically limited here.
[0044] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9The insulating shell also includes a second barrier 4 in a surrounding structure. The second barrier 4 is spaced apart on the side of the first barrier 3 away from the first connecting portion 12. One end of the second barrier 4 is connected to the second substrate 21, and the other end extends toward the first substrate 11 and partially extends into the interior of the first barrier 3. There is a gap between the second barrier 4 and the first substrate 11. The end of the second barrier 4 near the first substrate 11 is used to abut against the circuit board 8. The second barrier 4 is an insulating member. The end of the second barrier 4 away from the second substrate 21 extends into the interior of the first barrier 3. In this way, the first barrier 3 and the second barrier 4 partially overlap in the direction of the first substrate 11 toward the second substrate 21. When static electricity from outside the insulating shell enters the cavity 100, the static electricity bypasses the first barrier 3 and needs to pass through the side of the second barrier 4 near the first barrier 3 before reaching the circuit board 8, thereby further extending the static electricity creep path and improving the antistatic performance. In addition, in this embodiment, the insulating shell and the circuit board 8 are connected to the second shell body 2 by a connector (e.g., a self-tapping screw). The circuit board 8 is abutted against the end of the second barrier 4 near the first substrate 11. The circuit board 8 can be supported and positioned by the second barrier 4, which facilitates the installation of the circuit board 8.
[0045] See Figure 6 and Figure 7 The first shell component 1 also includes a plurality of first reinforcing ribs 13 disposed on the opposite side of the first substrate 11 and the second substrate 21. Each of the first reinforcing ribs 13 protrudes from the first substrate 11, and the plurality of first reinforcing ribs 13 are spaced apart around the first barrier member 3. The opposite ends of each of the first reinforcing ribs 13 are respectively connected to the first connecting portion 12 and the first barrier member 3. (See reference...) Figure 8 and Figure 9 The second shell component 2 also includes a plurality of second reinforcing ribs 23 disposed on the opposite side of the second substrate 21 and the first substrate 11. Each second reinforcing rib 23 protrudes from the second substrate 21 and is spaced around the second barrier member 4. The opposite ends of each second reinforcing rib 23 are connected to the second connecting portion 22 and the second barrier member 4, respectively. In this embodiment, the first substrate 11, the first connecting portion 12, the first reinforcing rib 13, and the first barrier member 3 are all integral structures, as are the second substrate 21, the second connecting portion 22, the second reinforcing member, and the second barrier member 4. Providing reinforcing ribs on the shell component and connecting the opposite ends of the reinforcing ribs to the connecting portion and the barrier member respectively helps prevent deformation of the barrier member during the molding of the shell component. Furthermore, since the insulating shell is installed on the vehicle, the reinforcing ribs strengthen the connection structure between the barrier member and the shell component, preventing the barrier member from breaking due to vehicle vibration.
[0046] Of course, in actual implementation, multiple first reinforcing ribs 13 may be provided only on the first substrate 11, or multiple second reinforcing ribs 23 may be provided only on the second substrate 21 as needed.
[0047] See Figure 4 and Figure 5 When the second shell component 2 includes multiple second reinforcing ribs 23, the first barrier 3 is opposite to each of the second reinforcing ribs 23. The first barrier 3 includes a barrier body 31 connected to the first substrate 11 and a foolproof protrusion 32 disposed on the end of the barrier body 31 away from the first substrate 11. The foolproof protrusion 32 protrudes from the barrier body 31, and a portion of the second reinforcing ribs 23 is opposite to the foolproof protrusion 32, while the remaining portion of the second reinforcing ribs 23 is opposite to the barrier body 31. The height H1 of the reinforcing rib 23 protruding from the second substrate 21 is less than the height H2 of the second reinforcing rib 23 protruding from the second substrate 21 opposite to the barrier body 31, so that the second reinforcing rib 23 can avoid the anti-mistake protrusion 32. With this design, when the first shell part 1 and the second shell part 2 are assembled incorrectly, the second reinforcing rib 23 opposite to the barrier body 31 will form positional interference with the anti-mistake protrusion 32 on the first shell part 1, so as to facilitate the correct assembly of the first shell part 1 and the second shell part 2.
[0048] In some embodiments, see Figure 2 The insulating shell also includes a connector for connecting the circuit board 8 to the second substrate 21. In this example, the connector is a self-tapping screw (not shown in the figure). The second substrate 21 is provided with a first connecting hole (not shown in the figure). The connector is used to pass through the first connecting hole and tighten into the hole structure on the circuit board 8 so that the circuit board 8 abuts against the second barrier 4. Specifically, the circuit board 8 is provided with a second connecting hole 7. The connector passes through the first connecting hole and tightens into the second connecting hole 7 so that the circuit board 8 abuts against the second barrier 4. In this way, when installing the circuit board 8, the second barrier 4 can provide support and positioning for the circuit board 8, which helps to reduce the difficulty of installing the circuit board 8.
[0049] See Figure 4 and Figure 5 The first barrier 3 has a gap with the circuit board 8, so that the first barrier 3 does not directly contact the circuit board 8, which is beneficial to further extend the static electricity creep path.
[0050] The insulating shell in some embodiments, see [link / reference]. Figure 4 and Figure 5The first connecting portion 12 protrudes from the side of the first substrate 11 near the second substrate 21, and the second connecting portion 22 protrudes from the side of the second substrate 21 near the first substrate 11. The height of the first connecting portion 12 protruding from the first substrate 11 is less than the height of the second connecting portion 22 protruding from the second substrate 21. When the first shell part 1 is located on the lower side of the second shell part 2, the first connecting portion 12 is positioned as close as possible to the bottom of the insulating shell as possible. In this way, when the height of the first barrier 3 protruding from the first substrate 11 remains unchanged, that is, when the overall height of the first barrier 3 remains unchanged, it is beneficial to increase the height difference between the position where the first connecting portion 12 and the second connecting portion 22 are connected and the end of the first barrier 3 away from the first substrate 11, thereby making the electrostatic creepage path longer.
[0051] In other embodiments of the insulating shell, when the height of the first barrier 3 protruding from the first substrate 11 remains unchanged, that is, when the overall height of the first barrier 3 remains unchanged, in order to increase the height difference between the position where the first connecting portion 12 and the second connecting portion 22 are connected and the end of the first barrier 3 away from the first substrate 11, the second connecting portion 22 may protrude from the side of the second substrate 21 near the first substrate 11, and the first connecting portion 12 may be flush with or recessed on the side of the first substrate 11 opposite to the second substrate 21.
[0052] In some embodiments, see Figure 1 , Figure 2 and Figure 6 The insulating shell also includes a snap-fit assembly 5, which includes a snap-fit protrusion 51 and a snap-fit plate 52 that engages with the snap-fit protrusion 51. One of the snap-fit protrusion 51 and the snap-fit plate 52 is disposed on the first shell segment 1, and the other is disposed on the second shell segment 2. In this embodiment, the snap-fit plate 52 is disposed on the first base plate 11 of the first shell segment 1, and the snap-fit protrusion 51 is disposed on the second connecting portion 22 of the second shell segment 2. The snap-fit plate 52 has snap-fit holes 521. When the first shell segment 1 and the second shell segment 2 are connected in place, the snap-fit protrusion 51 engages with the snap-fit holes 521 on the snap-fit plate 52, thereby locking the relative positions of the first shell segment 1 and the second shell segment 2. Multiple snap-fit assemblies 5 are provided, spaced apart, so that the first shell segment 1 and the second shell segment 2 can be locked in multiple parts.
[0053] In some embodiments, see Figure 1 and Figure 2The insulating shell also includes a bracket 6, which is used to mount the insulating shell onto the mounting component. In this embodiment, there are two brackets 6, spaced apart, and the insulating shell is mounted onto the mounting component via the two brackets 6. Specifically, one end of the bracket 6 is engaged with either the first shell component 1 or the second shell component 2, and the other end is connected to the external mounting component. The bracket 6 provides support for the entire insulating shell. In this embodiment, the end of the bracket 6 furthest from the mounting component is engaged with the second shell component 2.
[0054] In this embodiment, the second shell segment 2 further includes a snap-fit portion 24, which is disposed on the side of the second connecting portion 22 opposite to the cavity 100. The snap-fit portion 24 is used for snapping the bracket 6 in place. By snapping the bracket 6 into the snap-fit portion 24, it is easier for the bracket 6 to be assembled onto the mounting component. Of course, in other embodiments, the snap-fit portion 24 can also be disposed on the first shell segment 1.
[0055] In actual implementation, the number of snap-fit parts 24 can be set to multiple, with multiple snap-fit parts 24 arranged around the periphery of the second connecting part 22, and the two adjacent snap-fit parts 24 are spaced apart. By setting multiple snap-fit parts 24, the two brackets 6 can be snapped onto any two snap-fit parts 24 according to the location of the mounting parts in the car, which is beneficial for the insulating shell to adapt to the interior space of the car.
[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
