[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] The following is for reference. Figures 1-3 The fastener assembly 10 according to an embodiment of the present application is described. The fastener assembly 10 includes a gasket 11, a fastener 12 and a monitoring device 13.

[0032] The gasket 11 includes a first connecting end and a second connecting end, which are insulated from each other. A fastener 12 passes through the gasket 11 and can optionally be fitted to the gasket 11 to connect the first connecting end and the second connecting end. A monitoring device 13 is connected to both the first and second connecting ends, and the monitoring device 13 is adapted to detect whether the first and second connecting ends are connected to determine whether the fastener 12 and the gasket 11 are fitted together. Specifically, when the first connecting end and the second connecting end are connected, the fastener 12 is fitted to the gasket 11. When the first connecting end and the second connecting end are disconnected, the fastener 12 is separated from the gasket 11.

[0033] Currently, the tightness of engine mount bolts is crucial to the overall safety of a vehicle. Due to the prolonged vibrations and various loads experienced during vehicle operation, bolts are prone to loosening. If this is not detected and warned in time, it can lead to significant safety hazards, potentially causing engine displacement, engine damage and detachment, or even serious accidents such as the detachment of the half-shaft wheels. Existing bolt condition monitoring technologies mainly rely on periodic manual inspections, which are inefficient and prone to oversights, thus failing to effectively address the problem of accurate early warning of bolt loosening.

[0034] In response, this application proposes a fastener assembly 10 that can effectively monitor whether the fastener 12 is loose, thereby ensuring the stability of the engine and the safety of the vehicle.

[0035] like Figure 1 and Figure 2As shown, specifically, the fastener assembly 10 may include a gasket 11, a fastener 12, and a monitoring device 13. The gasket 11 may include a first connecting end and a second connecting end, which may be insulated from each other. It is understood that the first connecting end and the second connecting end cannot be directly connected; however, the connection method described above can be an electrical connection. The fastener 12 can be installed at the engine of the vehicle via the gasket 11. Specifically, the fastener 12 can be installed on the engine mount, and the fastener 12 can selectively abut against the gasket 11, thereby connecting the first connecting end and the second connecting end. Specifically, at least a portion of the fastener 12 can pass through the gasket 11 and connect to the engine mount. During assembly, the fastener 12 can abut against the gasket 11, causing the gasket 11 to adhere to the engine of the vehicle. In some embodiments, the fastener 12 can be a bolt, which is conductive. Therefore, when the fastener 12 abuts against the gasket 11, the fastener 12 can connect to the first connecting end and the second connecting end respectively, thereby enabling the first connecting end and the second connecting end to conduct through the fastener 12.

[0036] The monitoring device 13 can be connected to the first connection end and the second connection end respectively, and the monitoring device 13 can be used to detect whether the first connection end and the second connection end are conductive, and then determine whether the fastener 12 and the gasket 11 are in contact based on whether the first connection end and the second connection end are conductive. Specifically, when the first connection end and the second connection end are conductive, the fastener 12 and the gasket 11 are in contact; when the first connection end and the second connection end are disconnected, the fastener 12 and the gasket 11 are separated. Since the fastener 12 can be a conductive component, when the fastener 12 and the gasket 11 are in contact, they can be connected to the first connection end and the second connection end respectively. Therefore, the monitoring device 13 can further determine whether the fastener 12 and the gasket 11 are in contact by judging the connection relationship between the first connection end and the second connection end, thereby monitoring in real time whether the fastener 12 is loose. Compared with the prior art, the monitoring device 13 and the gasket 11 can more quickly and efficiently monitor whether the fastener 12 is loose, significantly improve the vehicle engine fastener 12 status monitoring capability, and reduce potential safety risks in vehicle operation and long-term maintenance and monitoring costs. In some embodiments, the monitoring device 13 may include structures such as a transistor, a micro-strain sensor, a high-precision vibration sensor, or an acoustic sensor.

[0037] In short, the fastener assembly 10 of this application embodiment has a first connection end and a second connection end that are insulated from each other on the gasket 11. The monitoring device 13 is connected to the first connection end and the second connection end respectively. The monitoring device 13 can determine whether the fastener 12 and the gasket 11 are in contact by detecting whether the first connection end and the second connection end are conductive. By adopting the above method, the tightness of the fastener 12 can be monitored more effectively, ensuring the stability of engine operation and ensuring the safety performance of the vehicle in complex operating environments.

[0038] like Figure 2 As shown, in some embodiments of this application, the gasket 11 may include a first connecting portion 111, a second connecting portion 112, and a third connecting portion 113. A first connecting end may be formed on the first connecting portion 111. One end of the second connecting portion 112 can be connected to the first connecting portion 111, and the other end of the second connecting portion 112 can be connected to the third connecting portion 113. A second connecting end may be formed on the third connecting portion 113. The first connecting end may be located at any position of the first connecting portion 111, and the second connecting end may be located at any position of the third connecting portion 113. The arrangement of the first connecting end and the second connecting end can be based on actual needs and is not limited here.

[0039] Furthermore, the first connecting portion 111 and the third connecting portion 113 are made of conductive material, while the second connecting portion 112 is made of insulating material. This ensures that the second connecting portion 112 can insulate the first connecting portion 111 and the third connecting portion 113, and that the first connecting end and the second connecting end can be insulated from each other. The first connecting portion 111, the second connecting portion 112, and the third connecting portion 113 can define a mounting hole 114. The mounting hole 114 can be provided through in the thickness direction, and the fastener 12 can pass through the mounting hole 114. In some embodiments, the inner wall of the mounting hole 114 is insulated from the fastener 12, thereby preventing the first connecting end and the second connecting end from remaining conductive after the fastener 12 is separated from the gasket 11. By adopting the above arrangement, the first connecting end and the second connecting end can be conductive when the first connecting portion 111 and the third connecting portion 113 are in contact with the fastener 12, thereby improving the reliability of the gasket 11.

[0040] In some embodiments of this application, an insulating layer can be provided on one side of the first connecting portion 111 along the thickness direction and on one side of the second connecting portion 112 along the thickness direction. The thickness direction can be the thickness direction of the gasket 11. Specifically, an insulating layer can be provided at the bottom of the first connecting portion 111 and the bottom of the second connecting portion 112. It can be understood that the bottom of the first connecting portion 111 can be the end of the first connecting portion 111 away from the contact point with the fastener 12, and the bottom of the second connecting portion 112 can be the end of the second connecting portion 112 away from the contact point with the fastener 12. By providing an insulating layer, the first connecting portion 111 and the second connecting portion 112 can be prevented from conducting electricity through the connection point with the engine, thereby improving the reliability of the insulating component. For example, the bottom of the first connecting portion 111 and the bottom of the second connecting portion 112 can be provided with a non-conductive paint film or other insulator.

[0041] like Figure 3 As shown, in some embodiments of this application, the monitoring device 13 may include a power supply 131, a detection element 132, and a resistor 133. The power supply 131 can be powered from inside the vehicle. The detection element 132 may have a first interface 1321, a second interface 1322, and a third interface 1323. The first interface 1321 may be connected to one end of the power supply 131, and the third interface 1323 may be connected to the other end of the power supply 131. One end of the resistor 133 may be connected to the power supply 131, and the other end of the resistor 133 may be connected to the second interface 1322. One of the first and second connection ends is connected to the other end of the resistor 133, and the other of the first and second connection ends is connected to the other end of the power supply 131. Regarding the connection, it should be noted that the detection element 132 can be a transistor. Transistors are low in cost and have higher reliability. When the power supply 131 is normally powered on, and the first and second connection terminals are conducting, there is no sufficient voltage difference between the second interface 1322 and the third interface 1323 of the detection element 132, so the detection element 132 remains in the off state. At this time, the detection element 132 is not powered. When the first and second connection terminals are disconnected, a sufficiently large voltage difference is generated between the second interface 1322 and the third interface 1323 of the detection element 132, causing the detection element 132 to enter the saturation region, thereby allowing the current to be guided from the first interface 1321 to the third interface 1323.

[0042] Furthermore, the fastener assembly 10 may also include an alarm element 134, which can be connected between the first interface 1321 and one end of the power supply 131. The alarm element 134 can emit a signal when current flows through it. Optionally, the alarm element 134 can warn the user through light, shadow, sound warning methods or by transmitting a signal to a remote alarm transmission device. Specifically, when the first and second connection ends are connected, the detection element 132 is kept in the off state. At this time, no current flows through the alarm element 134, and the alarm element 134 does not work. When the first and second connection ends are disconnected, a sufficiently large voltage difference is generated between the second interface 1322 and the third interface 1323 of the detection element 132. The detection element 132 allows current to flow from the first interface 1321 to the third interface 1323. At this time, the current flows from the power supply 131 to the alarm element 134, and then from the alarm element 134 to the first interface 1321. The alarm element 134 emits a signal when current flows through it, thereby reminding the user that the fastener 12 is loose.

[0043] In some embodiments of this application, the resistance value of resistor 133 can be R, satisfying the relationship: 5kΩ≤R≤100kΩ. It can be understood that the resistance value of resistor 133 can be any value between 5kΩ and 100kΩ. For example, the resistance value of resistor 133 can be, but is not limited to, 5kΩ, 35kΩ, 65kΩ, 100kΩ, etc. This setting can ensure that when the first connection terminal and the second connection terminal are conducting, there is no sufficient voltage difference between the second interface 1322 and the third interface 1323 of the detection element 132, thereby keeping the detection element 132 in the off state and improving the reliability of the monitoring device 13.
