Description

Technical Field

[0001] The utility model relates to the technical field of automobile electromagnetic shielding, in particular to a shielding device and electronic equipment. Background Art

[0002] Electronic devices may interfere with other devices or be interfered with by other devices when working. This requires that electronic devices have the ability to resist electromagnetic interference and cannot generate excessive electromagnetic radiation. In this case, electromagnetic compatibility (EMC) shielding has always been a core issue of automotive electronic equipment. However, traditional shielding solutions basically have problems such as poor contact, high probability of failure, and numerous processes.

[0003] For example, with regard to shielding solutions that bring the circuit board and the shell into direct contact to form a shielding space, on the one hand, the circuit board may be easily affected by installation tolerances, welding heat, materials, temperature, etc., causing warping and deformation; on the other hand, due to processing errors, the shell itself cannot be completely flat, so the two often have problems of not being able to contact or having poor contact.

[0004] For another example, based on the first shielding solution mentioned above, multiple metal springs are usually welded on the circuit board to solve the above-mentioned poor contact problem through elastic contact. However, the processing accuracy of the multiple metal springs is difficult to guarantee, and there are certain difficulties in welding positioning. At the same time, since the multiple metal springs are first welded to the circuit board and then the shell is assembled and contacted with the metal springs, it will bring a large cumulative tolerance. Therefore, the metal springs are easily flattened to make the shielding fail.

[0005] In addition, in order to solve the problems existing in the second shielding solution, a metal block (such as an aluminum block) for relieving stress can be arranged between the circuit board and the housing, and then a plurality of metal springs can be fixed on the housing so that the metal block on the circuit board contacts the metal springs on the housing. However, the connection process between the circuit board and the metal block, and between the metal springs and the housing is relatively cumbersome, and the installation is highly complex. Utility Model Content

[0006] The purpose of the utility model is to solve the problems of poor contact, complicated processing and installation process and high precision requirements of existing electromagnetic compatibility shielding structures. The utility model provides a shielding device that can ensure simple processing and installation process and low precision requirements on the basis of good contact and not easy to fail.

[0007] In order to solve the above technical problems, the embodiment of the utility model discloses a shielding device, comprising:

[0008] Shielding body;

[0009] An elastic portion, used for plugging into a circuit board, the elastic portion comprising at least one elastic member, each of the elastic members comprising a first portion and a second portion connected to each other, the first portion and the second portion being used to abut against two sides of the circuit board respectively along a first direction;

[0010] At least a portion of the shielding body facing the circuit board is in elastic contact with a second portion of the at least one elastic member.

[0011] By adopting the above technical solution, firstly, the elastic contact between the shielding body and the elastic part including at least one elastic member can eliminate the adverse effects of the shielding body and / or the circuit board such as lack of contact or poor contact due to manufacturing errors and assembly errors, that is, the shielding device of the embodiment of the present application has a better shielding effect.

[0012] Secondly, the elastic part can be directly plugged into the circuit board. This installation method has low precision requirements, simple installation, and low cost. It can avoid the high-precision and high-difficulty caused by the welding process, which can easily affect the warping and deformation of the circuit board. Moreover, since the elastic part is plugged into the circuit board, compared with the welding process, there will be no large cumulative tolerance when the elastic part contacts the shielding body, which can avoid the elastic part itself from being flattened and failing to a certain extent.

[0013] Specifically, after the elastic member is inserted into the circuit board, the first part and the second part of the elastic member abut against both sides of the circuit board along a first direction (for example, the thickness direction of the circuit board), that is, the first part and the second part abut against both sides of the circuit board in the same direction, which is relatively stable. Therefore, when the shielding body is elastically contacted with the second part later, it can ensure that the entire elastic member is not easily deformed (for example, being flattened), which can greatly reduce the failure probability of the shielding device.

[0014] In summary, the shielding device of the embodiment of the present application not only has a better shielding effect, but also has simple and efficient installation and low cost; at the same time, on the one hand, from the installation of the elastic part (that is, plug-in rather than welding), the cumulative tolerance after assembly with the shielding body is reduced, thereby ensuring the service life of the elastic part; on the other hand, from the abutment between the elastic part and the circuit board, since the first part and the second part abut against the circuit board in the same direction, they are less likely to deform than traditional metal springs, thereby further ensuring the service life of the elastic part.

[0019] According to another specific embodiment of the present invention, the elastic portion includes a plurality of elastic members, the plurality of elastic members are integrally formed, and the first portions of the plurality of elastic members are spaced apart.

[0035] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0036] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0037] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0038] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0039] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] See also Figure 1 , Figure 1 A traditional electromagnetic compatibility shielding design is shown, such as Figure 1 As shown, a metal spring 2' is added between the housing 1' and the circuit board 3'. Specifically, two metal springs 2' are welded on the circuit board 3'. It can be seen that the two metal springs 2' are in an open shape. When the housing 1' and the circuit board 3' are assembled, the housing 1' and the two metal springs 2' are in elastic contact, thereby effectively solving the technical problem of poor contact between the housing 1' and the circuit board 3'.

[0042] However, firstly, the processing accuracy of the metal dome 2' is difficult to ensure, and the positioning and welding between the metal dome 2' and the circuit board 3' are also difficult to process. Secondly, after the metal dome 2' is welded to the circuit board 3', the whole process of assembling the housing 1' to the circuit board 3' and contacting the metal dome 2' will produce cumulative tolerances. Figure 1 The metal spring piece 2' shown is easily crushed, thus causing the electronic device shielding failure.

[0043] The embodiment of the present application provides a shielding device and also provides an electronic device 100 using the shielding device. The shielding device of the electronic device 100 of the embodiment of the present application can ensure simple processing and installation processes and low precision requirements on the basis of good contact and not easy to fail, thereby effectively enhancing the electromagnetic shielding effect.

[0044] See also Figures 2 to 4 The shielding device of the embodiment of the present application includes a shielding body 1 and an elastic part 2.

[0045] The elastic part 2 is relatively independent and is used to be plugged into the circuit board 3. It can be seen that the elastic part 2 includes seven elastic parts 21, but the embodiment of the present application does not specifically limit the number of elastic parts 21. For example, the elastic part 2 of the embodiment of the present application can also include one, three, four, nine or other numbers of elastic parts 21, which can be selected according to the actual application scenario.

[0046] See also Figure 4 Combined with Figure 3 Each elastic member 21 includes a first portion 211 and a second portion 212 connected to each other. Exemplarily, the first portion 211 and the second portion 212 are connected by a connecting portion (i.e., the first connecting portion 213 and the second connecting portion described below), and the specific connection method will be described below. Figure 4 Combined with Figure 3 The first part 211 and the second part 212 are along the first direction (eg Figure 3 and Figure 4 The first portion 211 abuts against the top surface of the circuit board 3 (ie, the Z direction shown in FIG. 1 ). Figure 4The second portion 212 abuts against the bottom surface of the circuit board 3 (ie Figure 4 (in the direction of Z2).

[0047] See also Figure 4 Combined with Figure 2 , at least a portion of the shielding body 1 facing the circuit board 3 (for example, Figure 2 The edge 11 of the shielding body 1 shown in FIG. 1 is in elastic contact with the second portion 212 of each of the seven elastic members 21.

[0048] See also Figures 9 to 11 For example, during processing, the seven elastic members 21 are integrally formed, but the embodiment of the present application does not limit this. It can be seen that the first portions 211 of the seven elastic members 21 are spaced apart, and the embodiment of the present application does not limit the spacing between the first portions 211, for example, Fig. 9 and Fig.10 Two elastic parts at different spacings are shown respectively, which are all within the scope of protection required by the embodiments of the present application.

[0049] Based on this, see Figures 2 to 4 First, the elastic contact between the shielding body 1 and the elastic part 2 including at least one elastic member 21 can eliminate the adverse effects of the shielding body 1 and / or the circuit board 3 such as lack of contact or poor contact due to manufacturing errors and assembly errors, that is, the shielding device of the embodiment of the present application has a better shielding effect.

[0050] Secondly, the elastic part 2 can be directly plugged into the circuit board 3. This installation method has low requirements on precision, is simple to install, and has low cost. It can avoid the phenomenon of high precision and high difficulty caused by the welding process, which is easy to affect the warping and deformation of the circuit board 3; moreover, since the elastic part 2 is plugged into the circuit board 3, compared with the welding process, there will be no large cumulative tolerance when the elastic part 2 contacts the shielding body 1, which can avoid the elastic part 2 itself from being flattened and failing to a certain extent.

[0051] Specifically, after the elastic member 21 is plugged into the circuit board 3, the first portion 211 and the second portion 212 of the elastic member 21 are respectively connected along a first direction (for example, a thickness direction of the circuit board 3, such as Figure 2 In the Z direction shown in the figure, the first part 211 and the second part 212 abut against both sides of the circuit board 3, that is, the first part 211 and the second part 212 abut against both sides of the circuit board 3 in the same direction, which is relatively stable. Therefore, when the shielding body 1 and the second part 212 are elastically contacted later, it can ensure that the entire elastic member 21 is not easily deformed (for example, being flattened), which can greatly reduce the failure probability of the shielding device.

[0052] In summary, the shielding device of the embodiment of the present application not only has a better shielding effect, but also has simple and efficient installation and low cost. At the same time, on the one hand, from the installation of the elastic part 2 (that is, plug-in rather than welding), the cumulative tolerance after assembly with the shielding body 1 is reduced, and the service life of the elastic part 2 is guaranteed. On the other hand, from the abutment of the elastic member 21 with the circuit board 3, since the first part 211 and the second part 212 abut against the circuit board 3 in the same direction, compared with the traditional metal spring 2' (such as Figure 1 As shown in the figure, it is less likely to deform, which further ensures the service life of the elastic part 2.

[0053] Therefore, continue to refer to Figures 2 to 4 The electronic device 100 of the embodiment of the present application includes the above-mentioned shielding device, a circuit board 3 and an electronic component 4 (such as a high-frequency component). The electronic component 4 is electrically connected to the circuit board 3, the above-mentioned elastic part 2 of the shielding device is plugged into the circuit board 3, the shielding body 1 of the shielding device is assembled to the circuit board 3, and the shielding body 1 is in elastic contact with the elastic part 2.

[0054] In a possible implementation, the shielding body 1 is a part of a housing of the electronic device 100. Figures 2 to 4 The shielding body 1 shown in the figure is actually a part of the housing of the electronic device 100 (the complete housing is not shown in the figure), that is, the shielding body 1 is a shielding wall built by the housing of the assembled circuit board 3, and the shielding body 1 is arranged around the electronic component 4. For example, when the circuit board 3 is moved along the first direction (such as Figures 2 to 4 When the circuit board 3 is assembled to the housing (in the Z direction shown in FIG), the elastic portion 2 on the shielding body 1 can elastically contact with the shielding body 1, thereby forming a shielding space for accommodating the electronic component 4 to effectively shield it.

[0055] See also Figure 5 Combined with Figures 2 to 4 For example, it can be seen that the circuit board 3 is provided with seven connection slots 30, each of which is used for plugging each elastic member 21 of the elastic part 2. The embodiment of the present application does not specifically limit the number and shape of the connection slots 30. For example, one, three, four, nine, etc. connection slots 30 may be provided on the circuit board 3; the connection slots 30 may be in the form of Figure 5 The rectangle shown may also be a square, an ellipse, a trapezoid, etc. As long as the connecting grooves 30 correspond one-to-one with the elastic members 21 for the elastic members 21 to pass through, they all fall within the protection scope of the embodiments of the present application.

[0056] As can be seen from the foregoing, the elastic member 21 includes a first portion 211 and a second portion 212 . Hereinafter, the specific structure of the elastic portion 2 in the shielding device will be described in detail.

[0057] See also Figures 6 to 8 , Figure 6 A perspective view showing one of the elastic members 21 of the elastic portion as an example; Figure 7 A side view of one of the elastic members of the elastic portion is exemplarily shown; Figure 8 The side view of the connection between one of the elastic members of the elastic part and the circuit board 3 is exemplarily shown.

[0058] In a possible implementation, the elastic member 21 further includes a first connecting portion 213 and a second connecting portion 214 .

[0059] The first connection portion 213 is arranged along a first direction (eg Figure 6 The first connecting portion 213 includes a first end 2131 (i.e. Figure 6 The second end 2132 (ie Figure 6 The first end 2131 is used to move along Figure 8 The Z1 direction shown passes through the circuit board 3, and the second end 2132 is connected to the second connecting portion 214. The first portion 211 is arranged between the first end 2131 and the second end 2132, and the second portion 212 is arranged at an end of the second connecting portion 214 away from the second end 2132 (i.e. Figure 6 The end indicated by the Z2 direction).

[0060] In a possible implementation manner, the first portion 211 is inclined at an acute angle α relative to the first connecting portion 213, and one end of the first portion 211 (i.e. Figure 7 and Figure 8 The other end of the first part 211 (ie Figure 7 The abutting surface 2111 (indicated by direction b) includes abutting surface 2111, and the abutting surface 2111 is used to abut against the circuit board 3.

[0061] The embodiment of the present application does not limit the acute angle α between the first part 211 and the first connecting part 213. For example, it can be 15°, 22°, 30°, 51°, etc. As long as the abutting surface 2111 of the first part 211 can abut against the inclined angle of the circuit board 3 along the first direction, it falls within the protection scope of the embodiment of the present application.

[0062] See also Figure 6 The first connecting portion 213 is provided with a slot 2130, and the slot 2130 is along the first direction (such as Figure 6 The Z direction shown in FIG. 2 extends along the thickness direction of the first connecting portion 213 (eg, Figure 6 The first connecting portion 213 is penetrated by the slot 2130 (in the X direction shown in FIG). The slot 2130 corresponds to the first portion 211, so that the first portion 211 can be accommodated in the slot 2130.

[0063] See also Figures 6 to 8 In a possible implementation manner, the second portion 212 includes a contact portion 2122 and an abutting portion 2121, wherein the abutting portion 2121 is disposed along the second direction (eg Figure 7 and Figure 8 The abutting portion 2121 is used to abut against the circuit board 3. One end of the abutting portion 2121 (i.e. Figure 7 The Y1 direction in the figure) is connected to one end of the contact portion 2122 (i.e. Figure 7 The other end of the contact portion 2122 (i.e. Figure 7 The contact portion 2122 is connected to the second connection portion 214, and the contact portion 2122 is inclined at an acute angle θ relative to the corresponding second connection portion 214, so as to allow the shielding body 1 to elastically contact (such as Figure 8 shown).

[0064] The embodiment of the present application does not limit the acute angle θ between the contact portion 2122 and the second connecting portion 214, and can be, for example, 15°, 27°, 45°, 51°, etc. As long as the abutting portion 2121 connected to the contact portion 2122 can abut against the circuit board 3 along the first direction, and the contact portion 2122 can provide an inclination angle for contact with the shielding body 1, it falls within the protection scope of the embodiment of the present application.

[0065] In addition, the embodiment of the present application does not limit the sizes of the first portion 211, the second portion 212, the first connecting portion 213 and the second connecting portion 214. For example, Fig. 9 and Fig.10 Two elastic parts of different sizes are shown respectively, but both are within the scope of protection required by the embodiments of the present application.

[0066] See also Figures 2 to 8 Based on the above structural description, further, the first connecting portion 213 of each elastic member 21 in the elastic portion 2 of the embodiment of the present application can pass through the corresponding connecting groove 30 of the circuit board 3. During the insertion process, the first portion 211 is made of elastic material, so the first portion 211 will be squeezed by the inner wall of the connecting groove 30 and move toward the slot 2130 (in this process, Figure 8 The acute angle α shown is reduced) to be accommodated in the slot 2130 (at this time, Figure 8 The acute angle α shown is 0°), and at the same time, the first connecting portion 213 continues to move upward along the first direction (such as Figure 4 Then, the first portion 211 moves away from the slot 2130 (during this process, Figure 8 The acute angle α shown in the figure increases) until the abutting surface 2111 of the first portion 211 abuts against the top surface of the circuit board 3 (ie Figure 4The abutting portion 2121 of the second portion 212 abuts against the bottom surface of the circuit board 3 (ie, Figure 4 (in the direction of Z2).
