However, this varnish is easily damaged during assembly and disassembly, or when components are exposed to harsh operating environments, leading to a decrease in the insulation performance of the system. Therefore, there is a need for an insulation device with more stable insulation performance that is less prone to damage. Utility Model Content

[0049] It should also be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0050] See Figure 1 The figure is a schematic diagram of a bolt insulating washer provided in an embodiment of this application. The fixing bolt uses the bolt insulating washer to fix the object to be fixed to the fixing bracket.
[0051] like Figure 1 As shown, the bolt insulating pad provided in this embodiment includes: a first washer 100 and a second washer 200;
[0052] The first washer 100 is provided with a first through hole 101, the radius of which matches the radius of the bolt shank 302. The first washer 100 includes a bottom layer 102 and a middle layer 103 connected together. The first through hole 101 penetrates the bottom layer 102 and the middle layer 103. The second washer 200 is provided with a second through hole 201.
[0053] like Figure 2 As shown, the first washer 100 is used to be disposed between the object to be fixed 500 and the fixing bracket 400. The fixing hole 401 of the fixing bracket 400 is fitted onto the middle layer 103, and the external shape of the middle layer 103 matches the shape of the fixing hole 401 of the fixing bracket 400. The second washer 200 is used to be disposed between the bolt head 301 and the fixing bracket 400.
[0054] It should be noted that the bolt insulating gasket provided in this embodiment is made of insulating material, which enables insulation between the fixing bracket and the object to be fixed. In practical applications, the bolt insulating gasket can also be made of insulating material with high temperature resistance, corrosion resistance, and high mechanical strength to ensure mechanical strength between the object to be fixed and the fixing bracket. Figure 2As shown, the first washer 100 is used to prevent the fixing bracket 400 from directly contacting the bolt 300 and the object to be fixed 500, ensuring insulation between the object to be fixed 500 and the fixing bracket 400. The bolt 300 is fixed to the object to be fixed 500, meaning there is no insulating device between the bolt 300 and the object to be fixed 500. The second washer 200 is used to prevent the bolt 300 from contacting the fixing bracket 400, thereby ensuring insulation between the bolt 300 and the fixing bracket 400.
[0055] Therefore, the bolt insulating pad provided in this embodiment has relatively stable insulation performance, is not easily damaged during disassembly and assembly, and is not easily affected by exposure to harsh usage environments, thus making the insulation performance between the fixing bracket and the object to be fixed more stable and less prone to damage. Moreover, the bolt insulating pad in this embodiment can maintain a certain insulation distance between the fixing bracket and the object to be fixed, further improving the insulation stability between the fixing bracket and the object to be fixed.
[0056] In one possible implementation, the radius of the second through hole 201 in this embodiment can match the radius of the screw 302 of the bolt 300. It should be noted that when the radius of the second through hole 201 matches the radius of the screw 302 of the bolt 300, the second washer 200 can be directly fitted onto the end of the screw near the bolt head. The bolt head 301 of the bolt 300 presses against the second washer 200, and the screw 302 of the bolt 300 passes through the second through hole 201 and the first through hole 101 to be fixed to the object to be fixed.
[0057] As another possible implementation, such as Figure 3 and Figure 4 As shown, the first gasket 100 also includes a top layer 104, with the top layer 104, middle layer 103, and bottom layer 102 connected sequentially. A first through hole 101 passes through the top layer 104, middle layer 103, and bottom layer 102 sequentially. The external shape of the top layer 104 matches the shape of the second through hole 201. A fixing bracket 400 is disposed on the bottom layer 102, with its fixing hole fitted onto the middle layer 103. The second gasket 200 is fitted onto the top layer 104. It should be noted that fitting the second gasket 200 onto the top layer 104 simplifies the assembly of the bolt insulating gasket of this application and improves its mechanical stability.
[0058] The sum of the height of the fixing hole on the fixing bracket and the thickness of the second washer 200 is the same as the sum of the height of the top layer 104 and the height of the middle layer 103. Therefore, the upper surface of the top layer 104 and the upper surface of the second washer 200 are on the same horizontal plane. The bolt head 301 of the bolt 300 presses against the top layer 104 and the second washer 200, and the bolt shank 302 of the bolt 300 passes through the first through hole 101 and is fixed to the object to be fixed. The axial height of the middle layer 103 is less than or equal to the height of the fixing hole on the fixing bracket.
[0059] In this embodiment, the cross-sections of the bottom layer 102, the middle layer 103, and the top layer 104 of the first gasket 100 can all be circular or other shapes, and this embodiment does not limit them. Furthermore, the cross-sectional areas of the bottom layer 102, the middle layer 103, and the top layer 104 of the first gasket 100 decrease sequentially.
[0060] The bolt insulating pads provided in this application embodiment can be applied to fuel cell vehicles. When the bolt insulating pads in this application embodiment are applied to fuel cell vehicles, the object to be fixed can be a fuel cell stack. One end of the fixing bracket is connected to the fuel cell stack via the insulating bolt pads, and the other end of the fixing bracket is connected to the battery system of the fuel cell vehicle. In practical applications, the other end of the fixing bracket can be connected to the battery system of the fuel cell vehicle via bolts. The fixing bracket can be an "L"-shaped bracket, which is not limited in this application embodiment.
[0061] In summary, the bolt insulating pad provided in this embodiment has relatively stable insulation performance, is not easily damaged during assembly and disassembly, and is not easily affected by exposure to harsh operating environments, thus making the insulation performance between the fixing bracket and the object to be fixed more stable and less prone to damage. Furthermore, the bottom layer of the first washer in this embodiment maintains a certain insulating distance between the fixing bracket and the object to be fixed, further improving the insulation stability between them. In this embodiment, the second washer is fitted onto the top layer of the first washer, making the assembly of the bolt insulating pad simpler and providing better mechanical stability.
[0062] Based on the bolt insulating pad provided in the above embodiments, this application also provides an object fixing device.
[0063] like Figure 5 As shown, the object fixing device provided in this application embodiment includes a fixing bolt 300, a fixing bracket 400 and a bolt insulating washer. The fixing bolt 300 fixes the object to be fixed on the fixing bracket 400 through the bolt insulating washer. The bolt insulating washer includes: a first washer 100 and a second washer 200.
[0064] The first washer 100 is provided with a first through hole 101, the radius of which matches the radius of the bolt shank 302. The first washer 100 includes a bottom layer 102 and a middle layer 103. The second washer 200 is provided with a second through hole 201.
[0065] The first washer 100 is used to be placed between the object to be fixed 500 and the fixing bracket 400. The fixing hole 401 of the fixing bracket 400 is fitted onto the middle layer 103, and the external shape of the middle layer 103 matches the shape of the fixing hole 401 of the fixing bracket 400. The second washer 200 is used to be placed between the bolt head 301 and the fixing bracket 400.
