Description

Technical Field

[0001] The utility model relates to the technical field of vibration isolation, and more particularly to a vibration isolation device and electronic equipment. Background Art

[0002] PCBs (Printed Circuit Boards) provide electrical connections for electronic components. With a history of over 100 years, they are an indispensable component of modern electronic devices. They provide a method for securing electronic components to a mechanical carrier and connecting them via wires. The primary advantage of using PCBs is that they significantly reduce wiring and assembly errors, improving automation and productivity. PCB design is based on circuit schematics to achieve the functions required by the circuit designer.

[0003] Currently, PCBs are commonly installed by directly fastening them to the housing or other components. In some applications, PCBs are subject to severe shock and vibration loads. For example, the motor controller of an electric drive axle is subject to 300G acceleration and complex vibration conditions caused by bumpy roads. When the motor controller of an electric drive axle is subjected to shock and vibration loads, the internal PCB, which is directly fixed to the motor controller housing, transmits the shock and vibration loads directly to the PCB through the housing. As PCBs integrate an increasing number of components, high shock and vibration loads can damage the components on them, affecting the service life of the electronic device.

[0004] Therefore, how to improve the ability of printed circuit boards to resist impact and vibration loads and extend their service life is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a vibration isolation device to improve the ability of a printed circuit board to resist impact and vibration loads and to increase its service life;

[0006] Another object of the present invention is to provide an electronic device having the above-mentioned vibration isolation device.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A vibration isolation device, comprising:

[0009] A folding beam, the folding beam comprising a folding beam head end, a folding beam tail end, and a folding beam body portion, wherein a first end of the folding beam body portion is connected to the folding beam head end, and surrounds the folding beam head end to the second end of the folding beam body portion and is connected to the folding beam tail end;

[0010] A first mounting portion, connected to the head end of the folding beam, for connecting to one of the vibration-isolating member and the supporting mounting member;

[0011] The second mounting portion is connected to the tail end of the folding beam and is used to be connected to the other of the vibration-isolated component and the supporting mounting component.

[0012] Optionally, in the above-mentioned vibration isolation device, along at least one direction of each direction radiating outward from the head end of the folding beam, there are overlapping parts on the main body of the folding beam, and there are gaps between the overlapping parts.

[0013] Optionally, in the above-mentioned vibration isolation device, the main body of the folding beam includes a plurality of planar plates connected end to end, and the areas of the planar plates gradually increase along the direction radiating outward from the head end of the folding beam.

[0014] Optionally, in the above-mentioned vibration isolation device, the included angle between the two interconnected planar plates of the folding beam main body is 90°.

[0015] Optionally, in the above-mentioned vibration isolation device, the planar plates of the overlapping portion of the folded beam main body are parallel to each other.

[0016] Optionally, in the above-mentioned vibration isolation device, the main body of the folding beam is an arc panel that surrounds in a spiral shape.

[0017] Optionally, in the above-mentioned vibration isolation device, a first mounting plate is provided on the head end of the folding beam, and a second mounting plate is provided on the tail end of the folding beam;

[0018] The first mounting portion is disposed on the first mounting plate, and the second mounting portion is disposed on the second mounting plate.

[0019] Optionally, in the above-mentioned vibration isolation device, the first mounting plate and the second mounting plate are arranged in parallel, and along a direction perpendicular to the first mounting plate and the second mounting plate, one side of the first mounting plate and the second mounting plate is a first side, and the other side is a second side;

[0020] The first mounting portion is located on a first side of the first mounting plate, and the second mounting portion is located on a second side of the second mounting plate.

[0021] Optionally, in the above-mentioned vibration isolation device, the first mounting portion is a screw or a screw sleeve; and / or,

[0022] The second mounting portion is a screw or a threaded sleeve.

[0023] The vibration isolation device provided by the present invention utilizes a folded beam as the main body of the device. The folded beam main body extends outward from the head end of the folded beam until it connects to the tail end of the folded beam, resulting in a structure that wraps from the center outward. The folded beam as the main body of the vibration isolation device provides the device with high static stiffness, meaning it has the ability to support the isolated component and bear its weight. Furthermore, because the folded beam main body wraps from the center outward, it forms a multi-directional folded beam structure, ensuring low dynamic stiffness in all three spatial directions. This means that when vibrating, the stiffness of the isolated component is low, and the natural frequency of the vibration isolation device is low. When the natural frequency is sufficiently low, vibration isolation can be achieved within a range above the natural frequency. Furthermore, the folded beam has an extremely wide design range. By designing structural parameters such as the beam's cross-sectional shape and length, as well as selecting the beam's material, the design can adapt to the vibration isolation requirements of different isolated components. The present invention can improve the impact and vibration load resistance of isolated components, such as printed circuit boards, and thus increase their service life.

[0039] The core of this utility model is to provide a vibration isolation device to improve the ability of printed circuit boards to resist impact and vibration loads and increase their service life;

[0040] Another core of the present invention is to provide an electronic device having the above-mentioned vibration isolation device.

[0041] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0042] Currently, the printed circuit boards (PCBs) of electronic devices are typically mounted directly on the housing. Some electronic devices are subject to shock and vibration loads in their operating environments. For example, the motor controller of an electric drive axle is exposed to shocks of 300G acceleration and complex vibrations caused by bumpy roads. The housing transmits these shock and vibration loads to the PCB, causing damage and ultimately shortening the lifespan of the electronic device.

[0043] Based on this, the embodiment of the present utility model discloses a vibration isolation device to improve the ability of the printed circuit board to resist impact and vibration loads, thereby increasing the service life of the electronic equipment. Figure 1-Figure 3As shown, the vibration isolation device 100 disclosed in the embodiment of the present invention includes a folding beam 130 , a first mounting portion 110 and a second mounting portion 120 .

[0044] The folding beam 130 includes a folding beam head end 131, a folding beam tail end 132, and a folding beam main body 133. It should be noted that the folding beam head end 131 and the folding beam tail end 132 do not define the order of the manufacturing process. That is, the folding beam head end 131 does not refer to the starting section of the folding beam 130, and the folding beam tail end 132 does not refer to the ending section of the folding beam 130. These names are simply used to distinguish the two ends of the folding beam 130. The folding beam head end 131, the folding beam tail end 132, and the folding beam main body 133 can be designed as an integrated structure.

[0045] The first end of the folding beam main body 133 is connected to the folding beam head end 131. The main body 133 then wraps around the folding beam head end 131 until its second end is connected to the folding beam tail end 132. In other words, the folding beam main body 133 wraps outward from its first end. The number of wraps can be selected based on needs. The shape of the wrap can also be selected based on needs and is not limited to polygonal or curved shapes.

[0046] The first mounting portion 110 is connected to the head end 131 of the folding beam, and is used to connect to one of the vibration-isolating member 200 and the supporting mounting member. The second mounting portion 120 is connected to the tail end 132 of the folding beam, and is used to connect to the other of the vibration-isolating member 200 and the supporting mounting member. For example, the vibration-isolating member 200 can be connected to the first mounting portion 110, and the second mounting portion 120 can be connected to the supporting mounting member. When the vibration isolation device 100 is applied to electronic devices such as motor controllers of electric drive bridges, the vibration-isolating member 200 can be a printed circuit board of the electronic device, and the supporting mounting member can be a shell structure for supporting the printed circuit board. The vibration isolation device 100 disclosed in this embodiment can be arranged between the shell structure and the printed circuit board to improve the printed circuit board's ability to resist impact and vibration loads, thereby increasing the service life of electronic devices such as motor controllers.

[0047] The first mounting portion 110 and the second mounting portion 120 should be designed based on the actual application scenario to facilitate installation. For example, the first mounting portion 110 and the second mounting portion 120 can both be designed as screws, and corresponding fastening holes need to be opened on the vibration isolation member 200 and the supporting mounting member, and then the screws are passed through the fastening holes and fixed with nuts.

[0048] In addition, the first mounting portion 110 and the second mounting portion 120 can also be designed as screw sleeves, and correspondingly, fastening holes need to be opened on the vibration-isolating member 200 and the supporting mounting member, and then the fastener 300 is passed through the fastening hole and locked on the screw sleeve to achieve fastening. It should be noted that one of the first mounting portion 110 and the second mounting portion 120 can also be designed as a screw and the other as a screw sleeve, and the selection should be based on the specific installation environment to facilitate installation. In this embodiment, the first mounting portion 110 and the second mounting portion 120 are both designed as screw sleeves or screws, which can facilitate the rapid assembly and disassembly of the vibration isolation assembly.

[0049] It will be understood by those skilled in the art that the folding beam 130 has an extremely wide design range. For example, structural parameters such as the cross-sectional shape (including the cross-sectional shape of the plate body of the folding beam and the surrounding shape of the folding beam), the length of the beam (including the length of the plate body of the folding beam and the total surrounding length of the folding beam 130) can be designed, and there are also many options for the material of the folding beam (such as various types of metals, various types of plastics, etc.). Through structural design and material adjustment, printed circuit boards with different vibration isolation requirements can be adapted.

[0050] The vibration isolation device 100 provided by the present invention uses a folding beam 130 as the main body of the vibration isolation device 100. The folding beam main body 133 of the folding beam 130 starts from the head end of the folding beam and surrounds outward until it is connected to the tail end of the folding beam, so that the folding beam 130 as a whole has a structure that surrounds from the middle to the outside. The present invention uses the folding beam 130 as the main body of the vibration isolation device 100, so that it has a higher static stiffness, that is, it has the ability to support the vibration-isolated part and support the weight of the vibration-isolated part. In addition, because the folding beam main body 133 is a structure that surrounds from the center to the outside, it forms a multi-directional folding beam 130 structure, ensuring that it has low dynamic stiffness in three directions in space, that is, the stiffness of the vibration-isolated part 200 is low during vibration, and the natural frequency of the vibration isolation device 100 is low. When the natural frequency is low enough, vibration isolation can be achieved within a range higher than the natural frequency. Furthermore, the folded beam 130 has an extremely wide design range. By designing structural parameters such as the beam's cross-sectional shape and length, as well as selecting the beam's material, the folded beam 130 can be adapted to the vibration isolation requirements of different vibration-isolating components 200. This invention can improve the shock and vibration resistance of vibration-isolating components 200, such as printed circuit boards, and thus increase their service life.

[0051] like Figure 4 and Figure 5 As shown, in a specific embodiment of the present invention, along at least one direction of each direction radiating outward from the folding beam head end 131 (for example Figure 4 and Figure 5In the X direction and Y direction shown in the figure, there are overlapping parts of the folding beam main body 133, and there are gaps between the overlapping parts. It can be understood by those skilled in the art that the more overlapping parts of the folding beam main body 133, the more layers of circles surrounding the folding beam main body 133. Under the same material and structural conditions, the more layers, the stronger its vibration isolation ability, but its static stiffness will be reduced. Therefore, those skilled in the art should design the layers of circles surrounding the folding beam main body 133 according to the requirements of the application scenario, that is, design the number of overlapping parts of the folding beam main body 133. In addition, there are gaps between the overlapping parts, that is, the overlapping parts of the folding beam main body 133 refer to the multiple plates that will pass through the folding beam main body 133 in sequence in the direction radiating from the middle to the outside, and there are gaps between adjacent plates, so that the plates can deform in the direction of the gap to consume impact and vibration loads.

[0052] It should be noted that Figure 4 and Figure 5 The directions shown are only the directions of the X-axis and Y-axis in the plane coordinate system. Theoretically, when there are overlapping parts in the folding beam main body 133 in the X-axis direction and the Y-axis direction, the area between the X-axis direction and the Y-axis direction is also in the overlapping part.

[0053] Furthermore, the folding beam main body 133 comprises a plurality of planar panels connected end to end. That is, in this embodiment, each panel of the folding beam main body 133 is a planar panel, which is sequentially connected end to end. Because the planar panels, after being connected, gradually wrap around the folding beam head end 131 and outward, the area of ​​the planar panels closer to the folding beam head end 131 decreases, while the area of ​​the planar panels farther from the folding beam head end 131 increases. In other words, the area of ​​the planar panels gradually increases in a direction radiating outward from the folding beam head end 131. This is because the closer to the outer circle, the larger the area covered, necessitating planar panels with larger side lengths.

[0054] In the direction radiating from the middle to the outside, the closer to the outside, the longer the side length of each planar plate of the overlapping part of the folded beam main body 133, that is, the larger the area. The difference in the side lengths of two adjacent planar plates in the overlapping part is related to the gap between the planar plates, that is, if the side length difference is designed to be larger, a larger gap between the planar plates can be obtained; conversely, if the side length difference is designed to be smaller, a smaller gap between the planar plates can be obtained. Those skilled in the art can design the gap between the above-mentioned planar plates according to the application scenario of the vibration isolation component 200, that is, design the difference in the side lengths of two adjacent planar plates in the overlapping part.

[0055] Furthermore, the angle between the two interconnected planar plates of the folded beam main body 133 is 90°, that is, the two interconnected planar plates are perpendicular to each other. It should be noted that when the angle between the planar plates is designed to be 90°, five planar plates can form an overlapping area.

[0056] Those skilled in the art will appreciate that when the angle between the two interconnected planar plates of the folded beam main body 133 is less than 90°, the shape enclosed by the folded beam main body 133 can be triangular, so that four planar plates can form a single overlapping region. When the angle between the two interconnected planar plates of the folded beam main body 133 is greater than 90°, the shape enclosed by the folded beam main body 133 can be polygonal (with five or more sides), depending on the specific angle. Thus, six planar plates (taking the pentagonal shape enclosed by the folded beam main body 133 as an example) can form a single overlapping region.

[0057] The angle between the two interconnected planar plates of the folding beam main body 133 will affect the static stiffness and the ability to resist impact and vibration loads of the vibration isolation device 100. The more sides the polygon enclosed by the folding beam main body 133 has, the better its ability to resist impact and vibration loads, but the static stiffness is relatively weaker; on the contrary, the fewer sides the polygon enclosed by the folding beam main body 133 has, the weaker its ability to resist impact and vibration loads, but the static stiffness is relatively strong. Those skilled in the art can design the angle between the two planar plates based on the application scenario of the vibration isolation component 200.

[0058] It should be noted that the angles between any two interconnected planar plates can be designed to be equal or unequal. For example, the folding beam main body 133 can be arranged in a diamond structure, that is, the angles between the two interconnected planar plates can be of two types, one is an obtuse angle and the other is an acute angle.

[0059] In a specific embodiment of the present invention, the planar plates of the overlapping portion of the folded beam main body 133 are parallel to each other. Those skilled in the art may also design the planar plates of the overlapping portion to be non-parallel as needed. That is, the planar plates of the overlapping portion may be arranged at equal or unequal intervals.

[0060] In another embodiment of the present invention, the folding beam main body 133 can also be designed as a curved panel that winds into a spiral shape. Specifically, the folding beam main body 133 has a curved surface structure that winds into a spiral shape. Specifically, the choice of a flat panel structure or a curved panel structure can be determined based on the installation space requirements.

[0061] like Figure 3-Figure 5As shown, in order to facilitate the installation of the first mounting portion 110 and the second mounting portion 120 , in this embodiment, a first mounting plate 134 is provided on the head end 131 of the folding beam, and a second mounting plate 135 is provided on the tail end 132 of the folding beam.

[0062] The first mounting portion 110 is provided on the first mounting plate 134, and the second mounting portion 120 is provided on the second mounting plate 135. Since the first mounting portion 110 and the second mounting portion 120 need to extend in a certain direction to facilitate connection with the vibration-isolating member 200 and the supporting mounting member, if the first mounting portion 110 and the second mounting portion 120 are directly fixed on the folding beam head end 131 and the folding beam tail end 132, they will be constrained by the plate surface of the folding beam head end 131 and the folding beam tail end 132. For example, if the extension direction of the first mounting portion 110 and the second mounting portion 120 is required to be parallel to the plate surface of the folding beam head end 131 and the folding beam tail end 132, it will be difficult for the first mounting portion 110 and the second mounting portion 120 to be fixed on the folding beam head end 131 and the folding beam tail end 132. Based on this, in this embodiment, a first mounting plate 134 and a second mounting plate 135 are additionally added. The first mounting plate 134 and the second mounting plate 135 can facilitate fixing the first mounting portion 110 and the second mounting portion 120 in a set direction.

[0063] It should be noted that the first mounting plate 134 , the second mounting plate 135 , the folding beam head end 131 , the folding beam tail end 132 and the folding beam main body 133 can be designed as an integrated structure.

[0064] Taking the folding beam main body 133 as a planar plate, for example, if it is desired that the first mounting portion 110 and the second mounting portion 120 extend parallel to the planar plate, a first mounting plate 134 can be provided on the folding beam head end 131, and a second mounting plate 135 can be provided on the folding beam tail end 132. The first mounting plate 134 is perpendicular to the folding beam head end 131, and the second mounting plate 135 is perpendicular to the folding beam tail end 132. The first mounting portion 110 is fixed to the first mounting plate 134, and its extension direction is perpendicular to the first mounting plate 134. The second mounting portion 120 is fixed to the second mounting plate 135, and its extension direction is perpendicular to the second mounting plate 135. In this way, the extension directions of the first mounting portion 110 and the second mounting portion 120 are parallel to the planar plate of the folding beam head end 131, the folding beam tail end 132, and the folding beam main body 133.

[0065] Furthermore, since the folding beam head end 131 and the folding beam tail end 132 are also planar plates, and both are perpendicular to the planar plate of the folding beam main body 133 to which they are connected, in a spatial coordinate system, it can be understood that the first mounting plate 134, the folding beam head end 131, and the planar plate connected to the folding beam head end 131 are perpendicular to each other, so that the planes on which the three are located are parallel to the XYZ axes of the spatial coordinate system; correspondingly, the second mounting plate 135, the folding beam tail end 132, and the planar plate connected to the folding beam tail end 132 are perpendicular to each other, so that the planes on which the three are located are parallel to the XYZ axes of the spatial coordinate system.

[0066] It should be noted that the plane where the three are located should be the surface with the largest area of ​​the planar plate. Taking the planar plate as a rectangular plate as an example, the rectangular plate has three dimensions of length, width and height. The areas of its three mutually perpendicular surfaces are length multiplied by width, length multiplied by height, and width multiplied by height respectively. The three surfaces with the largest areas are the planes where the three mentioned above are located. The vibration isolation device disclosed in this embodiment forms a folded beam structure in three directions, further enhancing the vibration isolation capability in the three directions.

[0067] In a specific embodiment of the present invention, the first mounting plate 134 and the second mounting plate 135 are arranged in parallel, and in a direction perpendicular to the first mounting plate 134 and the second mounting plate 135, in order to distinguish the orientation, one side of the first mounting plate 134 and the second mounting plate 135 is defined as the first side, and the other side is defined as the second side. Figure 3 Taking viewing angles as an example, the upper and lower sides of the first and second mounting plates 134, 135 can be distinguished. Of course, in other embodiments, the left and right sides of the first and second mounting plates 134, 135 can also be distinguished based on the orientation of the plates. In this embodiment, to clarify the extending direction of the first mounting portion 110, the same directions of the first and second mounting plates 134, 135 are given the same name (e.g., first side and second side).

[0068] The first mounting portion 110 is located on a first side of the first mounting plate 134, and the second mounting portion 120 is located on a second side of the second mounting plate 135. That is, the first mounting portion 110 and the second mounting portion 120 extend in opposite directions to facilitate the installation of the vibration isolation device 100 between the vibration-isolated component 200 and the supporting mounting component.

[0069] The present invention also discloses an electronic device comprising a vibration-isolated component 200, a supporting mounting component, and a vibration isolation device 100. The vibration-isolated component 200 may be a printed circuit board or other component of the electronic device requiring vibration isolation.

[0070] The support mounting member can be a housing of an electronic device or another substrate inside the housing. The vibration isolation device 100 is the vibration isolation device 100 disclosed in the above embodiment, wherein one of the first mounting portion 110 and the second mounting portion 120 is connected to a printed circuit board, and the other is connected to the support mounting member.

[0071] Since the electronic device provided by the present invention includes the above-mentioned vibration isolation device 100 , it has all the technical effects of the above-mentioned vibration isolation device 100 , which will not be described in detail herein.
