[0035] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] Please refer to the following Figure 1-5 A shielding isolation structure 100 according to an embodiment of the present invention is described.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 According to the shielding isolation structure 100 of the embodiment of the present invention, it is used to shield the interference between multiple electrical components 200. The shielding isolation structure 100 includes: a supporting part 10 and multiple shielding parts 20. The number of shielding parts 20 can be two, three, four or five or more.

[0038] Specifically, the shielding portion 20 is connected to the supporting portion 10 and extends along the thickness direction of the supporting portion 10. The plurality of shielding portions 20 extend along the first direction (eg Figure 1 The shielding parts 20 and the supporting parts 10 are arranged at intervals (in the left and right directions as shown), and limiting grooves 30 are defined between adjacent shielding parts 20 and supporting parts 10. The plurality of limiting grooves 30 are suitable for accommodating the electrical components 200.

[0039] For example, Figure 1 、 Figure 2 and Figure 3 As shown, the support portion 10 is plate-shaped and extends in the left-right direction. The lower end of the shielding portion 20 is connected to the support portion 10, and the upper end of the shielding portion 20 extends upward. Multiple shielding portions 20 are arranged at intervals in the left-right direction. Two shielding portions 20 cooperate with one support portion 10 to define a limiting groove 30 with an open top. When the electrical component 200 is placed in the limiting groove 30, it can play a role in isolating the electrical component 200. Preferably, the shielding isolation structure 100 is a sheet metal part or an injection molded part. Sheet metal parts or injection molded parts are easy to obtain, thereby facilitating the processing of the shielding isolation structure 100. The cross-section of the limiting groove 30 can be trapezoidal, square, triangular, or semicircular, which can facilitate the installation of the electrical component 200 in the limiting groove 30.

[0040] The shielding isolation structure 100 of the present invention is provided with a shielding part 20, and the adjacent shielding parts 20 cooperate with the supporting part 10 to form a limiting groove 30. When the electrical component 200 is placed in the limiting groove 30, the shielding part 20 can weaken the interference signal of the adjacent electrical component 200. Even if the signal frequencies transmitted by the adjacent electrical components 200 differ too much, they will not interfere with each other, thereby ensuring the electromagnetic shielding performance of the shielding isolation structure 100, and further ensuring that the electrical components 200 transmit signals normally. At the same time, it can also facilitate the arrangement of the electrical components 200. Moreover, compared with the prior art solution that requires increasing the spacing between adjacent electrical components 200 to reduce the interference between the electrical components 200, the shielding isolation structure 100 of the present application can shield the interference between the adjacent electrical components 200 by placing the adjacent electrical components 200 in the accommodating groove 30, without increasing the distance between the adjacent electrical components 200 to reduce the interference, thereby reducing the distance between multiple electrical components 200, and further reducing the occupied space of the electrical components 200, thereby improving space utilization. In addition, the limiting groove 30 has sufficient heat dissipation space, thereby ensuring the heat dissipation requirements of the electrical component 200 and effectively preventing the electrical component 200 from being damaged by high temperature.

[0041] According to the shielding isolation structure 100 of the embodiment of the present invention, a shielding portion 20 is provided on the supporting portion 10. The shielding portion 20 can reduce the interference of adjacent electrical components 200, thereby ensuring the electromagnetic shielding performance, and further ensuring that the electrical components 200 can transmit signals normally. At the same time, it can also reduce the occupied space of multiple electrical components 200 and improve space utilization.

[0042] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 The shielding portion 20 includes a baffle, one end of the baffle (such as Figure 2 The lower end of the baffle shown in FIG) is connected to the support portion 10 and the other end (as shown Figure 2 The upper end of the baffle shown in FIG) along the thickness direction of the support portion 10 (as shown Figure 2 The baffle plate is provided with a vertical direction (in the vertical direction of the support portion 10 shown in FIG. 1 ) and extends away from the support portion 10. Thus, the baffle plate has a simple structure and is easy to manufacture, thereby facilitating the processing of the shielding portion 20.

[0043] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 4 The shielding portion 20 includes two baffles, and the two baffles are a first baffle 21 and a second baffle 22. One end of the first baffle 21 (such as Figure 2 The lower end of the first baffle 21 shown in FIG) and one end of the second baffle 22 (as shown Figure 2The lower end of the second baffle 22 shown in FIG. 1 is connected to the support portion 10 and extends in the first direction (eg Figure 2 The left and right directions shown in FIG) are arranged at intervals, and the other end of the first baffle 21 (as shown Figure 2 The upper end of the first baffle 21 shown in FIG) and the other end of the second baffle 22 (as shown in FIG). Figure 2 The upper end of the second baffle 22 shown in FIG. 2 is along the thickness direction of the support portion 10 (eg Figure 2 The upper and lower directions of the support portion 10 shown extend away from the support portion 10.

[0044] In this way, the first baffle 21 and the second baffle 22 are both connected to the support part 10, thereby ensuring the connection strength of the first baffle 21 and the second baffle 22 and the support part 10, and thus effectively preventing the first baffle 21 and the second baffle 22 from being deformed and damaged. At the same time, the other ends of the first baffle 21 and the second baffle 22 are connected, thereby further ensuring the connection reliability between the first baffle 21 and the second baffle 22, and thus effectively preventing the first baffle 21 and the second baffle 22 from being bent and damaged.

[0045] For example, Figure 2 and Figure 4 As shown, the first baffle 21 extends vertically in the up-down direction, the lower end of the first baffle 21 is connected to the support part 10, the upper end of the second baffle 22 extends upward, the second baffle 22 extends vertically in the up-down direction, the lower end of the second baffle 22 is connected to the support part 10, the upper end of the second baffle 22 extends upward, and the upper end of the first baffle 21 is connected to the upper end of the second baffle 22.

[0046] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 The shielding portion 20 may further include: a connecting section 23, the connecting section 23 along the first direction (such as Figure 2 The two ends of the connecting section 23 in the first direction are respectively connected to the other end of the first baffle 21 (as shown in the left and right directions). Figure 2 The upper end of the first baffle 21 shown in FIG) and the other end of the second baffle 22 (as shown in FIG). Figure 2 The upper end of the second baffle 22 is shown).

[0047] In this way, the connecting section 23 can facilitate the connection between the first baffle 21 and the second baffle 22, thereby reducing the processing difficulty and eliminating the need to consider whether the connection position of the first baffle 21 and the second baffle 22 can be connected. At the same time, the connecting section 23 cooperates with the first baffle 21 and the second baffle 22 to prevent the electrical component 200 from being cut at the connection position of the first baffle 21 and the second baffle 22, thereby effectively protecting the electrical component 200.

[0048] For example, Figure 2 and Figure 4As shown, the connecting section 23 extends horizontally in the left-right direction, the left end of the connecting section 23 is connected to the upper end of the first baffle 21 , and the right end of the connecting section 23 is connected to the upper end of the second baffle 22 .

[0049] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 4 In the direction from the support portion 10 to the connecting section 23, the first baffle 21 extends obliquely toward the second baffle 22, and the second baffle 22 extends obliquely toward the first baffle 11. Thus, the first baffle 21 and the second baffle 22 extend toward each other, which can increase the stability of the first baffle 21 and the second baffle 22, thereby preventing deformation and damage to the first baffle 21 and the second baffle 22. At the same time, the space in the limiting groove 30 can be expanded, thereby facilitating the installation of the electrical component 200.

[0050] For example, Figure 2 and Figure 4 As shown, the first baffle 21 extends obliquely upward from the lower left to the upper right, and the second baffle 22 extends obliquely upward from the lower right to the upper left.

[0051] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The baffle is provided with a first through hole 211, and the first through hole 211 is along the thickness direction of the baffle (such as Figure 2 The first through-hole 211 extends through the baffle (in the left-right direction of the baffle shown). Thus, the first through-hole 211 provided on the baffle does not reduce the insulating effect of the shielding portion 20. This reduces the weight of the shielding isolation structure 100 while ensuring the shielding effect, thereby reducing production costs. Furthermore, heat from the electrical component 200 can be dissipated through the first through-hole 211, thereby improving the heat dissipation efficiency of the shielding isolation structure 100.

[0052] For example, Figure 2 and Figure 4 As shown, the first baffle 21 is provided with a plurality of first through holes 211. Figure 2 The B in the figure is the arrangement area of ​​the first through holes 211. A plurality of first through holes 211 are arranged at intervals along the front-to-back direction of the first baffle 21. The first through holes 211 penetrate the first baffle 21 along the left-to-right direction.

[0053] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 4 , the first height h of the first through hole 211 satisfies: h=λ / 10, wherein the first height h is the distance between the first through hole 211 at both ends of the first through hole 211 in the direction from one end to the other end of the baffle (such as Figure 4The distance between the upper and lower edges of the first through hole 211 is shown, and λ is the wavelength corresponding to the highest frequency of the signal transmitted by the electrical component 200. Thus, the height of the first through hole 211 is adapted to the frequency of the signal transmitted by the electrical component 200, thereby preventing the first through hole 211 from affecting the shielding effect of the shielding isolation structure 100 on the signal of the electrical component 200.

[0054] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The electrical component 200 is a wiring harness, and the depth of the limiting groove 30 is greater than or equal to twice the diameter of the electrical component 200. This facilitates the arrangement of the electrical components 200, thereby improving wiring efficiency. At the same time, the shielding effect of the shielding isolation structure 100 is ensured, effectively preventing electrical components 200 in adjacent limiting grooves 30 from interfering with each other.

[0055] For example, Figure 1 and Figure 2 As shown, the depth of the limiting groove 30 can be 2 times, 3 times, 4 times, 5 times, 6 times or 7 times or more of the diameter of the electrical component 200.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, the width of the limiting groove 30 is designed according to the diameter and number of the electrical components 200 , so that the shielding isolation structure 100 can be adapted to a variety of electrical components 200 .

[0057] Furthermore, if Figure 1 As shown, when the electrical component 200 is disposed in the limiting groove 30 , it is fixed using wire clips, cable ties, adhesive tape, and other measures, thereby effectively preventing the electrical component 200 from shaking in the limiting groove 30 .

[0058] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 The support portion 10 includes a plurality of support plate segments 11, that is, the support portion 10 may include two, three or four or more support plate segments 11, and the plurality of support plate segments 11 and the plurality of shielding portions 20 are arranged along a first direction (such as Figure 2 Thus, the plurality of support plate segments 11 and the plurality of shielding portions 20 cooperate to form a plurality of limiting grooves 30, thereby accommodating a plurality of electrical components 200, thereby meeting the arrangement requirements of the plurality of electrical components 200.

[0059] For example, Figure 2 and Figure 3As shown, the support portion 10 includes four support plate segments 11 and the shielding portion 20 includes three. The four support plate segments 11 and the three shielding portions 20 are alternately arranged along the left-right direction, and adjacent support plate segments 11 are connected to the shielding portion 20 .

[0060] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 5 The support portion 10 is provided with a second through hole 111, and the second through hole 111 is along the thickness direction of the support portion 10 (such as Figure 2 The second through hole 111 extends through the support portion 10 (in the vertical direction of the support portion 10 shown). This further reduces the weight of the shielding isolation structure 100, thereby lowering production costs and facilitating assembly and transportation. Furthermore, heat from the electrical component 200 can be dissipated through the second through hole 111, further improving the heat dissipation efficiency of the shielding isolation structure 100.

[0061] For example, Figure 1 and Figure 2 As shown, each support plate segment 11 is provided with a plurality of second through holes 111. Figure 2 A in the figure is the arrangement area of ​​the second through holes 111. The second through holes 111 penetrate the support plate segment 11 in the up-down direction. A plurality of second through holes 111 are arranged at intervals in the front-to-back direction of the support plate segment 11.

[0062] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 The support portion 10 and the shielding portion 20 are formed as an integral part. Thus, the strength of the shielding isolation structure 100 can be ensured, thereby effectively preventing the shielding isolation structure 100 from being damaged.

[0063] Furthermore, if Figure 1 and Figure 2 As shown, the support portion 10 and the shielding portion 20 are metal. As such, metal components can provide electrostatic shielding. Therefore, using the support portion 10 and the shielding portion 20 as metal components can ensure the signal shielding effect of the shielding isolation structure 100 while also ensuring the strength of the shielding isolation structure 100. Preferably, the shielding isolation structure 100 is integrally die-cast, which can ensure the strength of the shielding isolation structure 100 and improve the processing efficiency of the shielding isolation structure 100.

[0064] According to the electrical equipment of the second embodiment of the present utility model, Figure 1 , including an electrical component 200 and the shielding isolation structure 100 of the first aspect of this embodiment, the electrical component 200 is accommodated in the limiting groove 30. For example, Figure 1 As shown, there are two electrical components 200 , and the two electrical components 200 are respectively disposed in two corresponding limiting grooves 30 .

[0065] According to the electrical equipment of the embodiment of the present invention, by setting the shielding isolation structure 100 of the above-mentioned first embodiment, a shielding part 20 is set on the supporting part 10. The shielding part 20 can reduce the interference of adjacent electrical components 200, thereby ensuring the electromagnetic shielding performance, and further ensuring that the electrical components 200 transmit signals normally. At the same time, it can also reduce the space occupied by the electrical components 200 and improve space utilization.

[0066] According to some embodiments of the present invention, referring to Figure 1 The electrical device further comprises a metal housing, and the shielding isolation structure 100 is electrically connected to the metal housing. Thus, a short circuit between the electrical component 200 and the shielding isolation structure 100 can be prevented, thereby ensuring safe use.

[0067] Furthermore, if Figure 1 As shown, the electrical device further includes a ground wire, which is electrically connected to the shielding isolation structure 100. This prevents short circuits between the electrical component 200 and the shielding isolation structure 100, thereby ensuring safe use.

[0068] According to the vehicle of the third embodiment of the present utility model, Figure 1 , including the electrical equipment of the second aspect of this embodiment.

[0069] According to the vehicle of the embodiment of the present utility model, by setting the electrical equipment of the above-mentioned second embodiment, the shielding isolation structure 100 of the above-mentioned first embodiment is set on the electrical equipment, and the shielding part 20 is set on the support part 10.
