Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a detection component and a vehicle. Background Art

[0002] With the popularization of vehicles, people have put forward higher requirements for the safety of vehicle operation.

[0003] In the process of conceiving and implementing this application, the applicant found that there are at least the following problems: during the operation of the vehicle, when the vehicle parts become loose, relative displacement may occur in the dynamic environment of the vehicle, which may lead to collisions between different parts. However, the initial loosening of parts is relatively minor and has little impact on the vehicle, and is not easy to detect. From the appearance, the vehicle as a whole is normal. Due to the slight degree of looseness, the displacement between parts is very small, which hardly causes obvious changes in appearance. The gap changes with surrounding parts are also very subtle, which is difficult to detect without careful observation.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention

[0005] In view of the above problems, the present invention provides a detection component and a vehicle, which can accurately determine the degree and position of looseness of vehicle parts and improve the accuracy of detection; in addition, it can realize the self-powered function without the need for an external power supply.

[0006] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0007] In a first aspect, an embodiment of the present invention provides a detection component, which is applied to a vehicle, and the detection component includes:

[0008] A first detection member is disposed in a first area of ​​the vehicle;

[0009] A second detection member is disposed in a second area of ​​the vehicle, the first detection member and the second detection member are disposed opposite to each other, and when the first area of ​​the vehicle and the second area of ​​the vehicle move relative to each other, an electrical signal is generated between the first detection member and the first detection member;

[0010] The induction element is used to receive electrical signals to send out alarm signals.

[0011] The beneficial effects of the present invention are as follows: through the arrangement of the first detection member, the first detection member and the sensing member, the relative movement between different areas of the vehicle can be monitored in real time, and the degree and position of the looseness can be accurately judged through the change of the electrical signal, thereby improving the accuracy of the detection, timely discovering the looseness problem, and performing maintenance and repairs at an early stage to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle; in addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals at the early stage of component loosening; in addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy, and does not require a battery for power supply. When the first detection member and the first detection member contact and collide with each other, a signal can be transmitted, providing a self-powered function for the sensing member, without the need for an external power supply.

[0012] Based on the above technical solution, the present invention can also be improved as follows.

[0013] In some optional embodiments, at least one of the first detection member and the second detection member is a flexible member.

[0014] It is understood by the skilled person in the present application that flexible parts can adapt to the shape and movement characteristics of different areas of the vehicle, especially on complex or irregular surfaces, ensuring that the detection assembly can fit tightly and accurately detect looseness. In addition, flexible parts are usually lighter than rigid parts, which helps to reduce the overall weight of the vehicle, thereby improving fuel efficiency and vehicle performance.

[0015] In some optional embodiments, the first area of ​​the vehicle and the second area of ​​the vehicle are arranged opposite to each other, and there is a first gap between the first area of ​​the vehicle and the second area of ​​the vehicle;

[0016] When the first gap increases or decreases, an electrical signal is generated between the first detection member and the second detection member.

[0017] It can be understood by the technicians of this application that by detecting the change in the first gap, the looseness or tightness of the vehicle component structure can be sensitively sensed, and the electrical signal caused by the gap change can be transmitted to the sensing part in real time, providing instant feedback information, so that the vehicle operator or maintenance personnel can take quick measures, which helps to detect potential problems at an early stage.

[0018] In some optional embodiments, the first detection member includes a first friction layer and a first electrode layer, the first friction layer is disposed on the first region of the vehicle, and the first electrode layer is disposed on the first friction layer;

[0019] The second detection member includes a second friction layer and a second electrode layer, the second friction layer is arranged on the second area of ​​the vehicle, and the second electrode layer is arranged on the second friction layer, wherein the electrical property of the first friction layer is different from the electrical property of the second friction layer;

[0020] When the first area of ​​the vehicle and the second area of ​​the vehicle move relative to each other, the first friction layer and the second friction layer contact or separate from each other, so that an electrical signal is generated between the first electrode layer and the second electrode layer.

[0021] It is understood by the technical personnel of the present application that by utilizing the triboelectric effect, an electrical signal can be generated when two areas move relative to each other. Since the triboelectric effect is very sensitive to contact and separation, the system can detect small relative movements and gap changes, thereby achieving highly sensitive looseness detection. In addition, it also provides a possibility of self-powering, reducing the dependence on external power supply.

[0022] In some optional embodiments, the first detection member further includes a first base layer, the first base layer has a first adhesive surface and a second adhesive surface, the first adhesive surface is attached to the surface of the first area of ​​the vehicle, the first friction layer is attached to the second adhesive surface, and the first electrode layer is attached between the first friction layer and the second adhesive surface; and / or,

[0023] The second detection member also includes a second base layer having a third adhesive surface and a fourth adhesive surface, the third adhesive surface is attached to the surface of the second area of ​​the vehicle, the second friction layer is attached to the fourth adhesive surface, and the second electrode layer is attached between the second friction layer and the fourth adhesive surface.

[0024] The technical personnel of the present application can understand that by adding the first base layer and the second base layer, the overall structure of the detection assembly is more stable, and can better resist external vibration and impact, ensuring the reliability of detection. The first base layer and the second base layer provide adhesive surfaces, so that the first detection member and the second detection member can be easily installed on different areas of the vehicle, ensuring the correct positioning and function realization of the friction layer and the electrode layer.

[0025] In some optional embodiments, at least one of the first base layer and the second base layer is an adhesive-backed member.

[0026] It can be understood by the technical personnel of the present application that the design of the adhesive backing allows the detection component to be directly affixed to the designated area of ​​the vehicle without the need for additional fixings or tools, thereby simplifying the installation process and saving time and manpower; the adhesive backing usually has excellent adhesion properties and can be firmly fixed to the vehicle surface, ensuring that the detection component remains stable during the operation of the vehicle and is not easy to fall off.

[0027] In some optional embodiments, one of the materials of the first friction layer and the second friction layer is a high molecular polymer, and the other is a high molecular compound.

[0028] It is understood by the skilled person in the present application that since polymers and polymer compounds have different electrical properties, when they come into contact or separate from each other, a significant triboelectric effect will be generated. This material combination can enhance the generation of electrical signals and improve the sensitivity and accuracy of detection.

[0029] In some optional embodiments, the first friction layer is made of polytetrafluoroethylene; and / or,

[0030] The material of the second friction layer is polyhexamethylene terephthalamide.

[0031] It is understood by those skilled in the art that polytetrafluoroethylene and polyhexamethylene terephthalamide have different electrical properties, and when they are in contact or separated from each other, a significant triboelectric effect will be generated. This material combination can effectively generate an electrical signal for detecting relative movement between vehicle regions.

[0032] In some optional embodiments, the first detection member is a first magnetic member and a Hall chip, and the second detection member is a second magnetic member;

[0033] When the first area of ​​the vehicle and the second area of ​​the vehicle move relative to each other, the Hall chip generates an electrical signal according to the change of the magnetic field between the first magnetic member and the second magnetic member.

[0034] It is understood by the technical personnel of the present application that the Hall effect chip can accurately detect small changes in the magnetic field, and therefore can sensitively sense the relative movement between the first area and the second area of ​​the vehicle. This high sensitivity helps to detect looseness or displacement problems in a timely manner. The Hall effect sensor can quickly respond to changes in the magnetic field and provide real-time electrical signal output, so that the system can immediately feedback changes in the vehicle status.

[0035] In a second aspect, an embodiment of the present invention further provides a vehicle, comprising a vehicle body and the above-mentioned detection component.

[0036] The present invention provides a detection component and a vehicle, the vehicle comprising a vehicle body and the above-mentioned detection component. The detection component is applied to the vehicle, and the detection component comprises: a first detection member, which is arranged in a first area of ​​the vehicle; a second detection member, which is arranged in a second area of ​​the vehicle, the first detection member and the second detection member are arranged relative to each other, and when the first area of ​​the vehicle and the second area of ​​the vehicle move relative to each other, an electric signal is generated between the first detection member and the first detection member; and an induction member, which is used to receive the electric signal to send out an alarm signal.

[0037] By setting up the first detection member, the first detection member and the sensing member, the relative movement between different areas of the vehicle can be monitored in real time. Through the change of the electrical signal, the degree and position of the looseness can be accurately determined, the accuracy of the detection can be improved, and the looseness problem can be discovered in time. Maintenance and repairs can be carried out in the early stages to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle; in addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals in the early stages of component loosening; in addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy, and does not require a battery for power supply. When the first detection member and the first detection member contact and collide with each other, they can transmit signals, providing a self-powered function for the sensing member without the need for an external power supply.

[0070] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

All other embodiments obtained are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0071] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0072] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] It should be noted that in the description of the present invention, the terms "first", "second", and "third" are only used to facilitate the description of different components, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0074] At present, when vehicle parts become loose during vehicle operation, relative displacement may occur in the dynamic environment of vehicle driving, which may lead to collision between different parts. However, the initial loosening of parts is relatively minor and has little impact on the vehicle, and it is not easy to detect. From the appearance, there is no abnormality in the vehicle as a whole. Due to the slight degree of looseness, the displacement between parts is very small, which will hardly cause obvious changes in appearance. The gap changes with surrounding parts are also very subtle, which is difficult to detect without careful observation.

[0075] In order to overcome the defects in the prior art, the present invention provides a detection component and a vehicle, which can monitor the relative movement between different areas of the vehicle in real time through the arrangement of a first detection member, a first detection member and a sensing member, and can accurately judge the degree and position of looseness through the change of electrical signals, thereby improving the accuracy of detection, discovering looseness problems in time, and performing maintenance and repairs at an early stage to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle; in addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals in the early stages of component loosening; in addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy, and does not require a battery for power supply. When the first detection member and the first detection member contact and collide with each other, a signal can be transmitted, providing a self-powered function for the sensing member, without the need for an external power supply.

[0076] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] The content of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the content of the present invention more clearly and in detail.

[0079] like Figures 1 to 6 As shown, the embodiment of the present application provides a detection component 100, which is applied to a vehicle 200. The detection component 100 includes:

[0080] The first detection element 110 is disposed in a first area 211 of the vehicle 200;

[0081] The second detection member 120 is disposed in the second area 212 of the vehicle 200. The first detection member 110 and the second detection member 120 are disposed opposite to each other. When the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 move relative to each other, an electrical signal is generated between the first detection member 110 and the first detection member 110.

[0082] The induction element 130 is used to receive an electrical signal to send out an alarm signal.

[0083] It should be noted that the first area 211 of the vehicle 200 is an area on any structural member of the vehicle 200 , and correspondingly, the first area 211 of the vehicle 200 is another area on any structural member of the vehicle 200 .

[0084] The structural parts are all parts of the vehicle 200 and may be some appearance structural parts of the vehicle 200 .

[0085] It should be noted that the relative movement of the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 may include when the vehicle 200 is driving normally, wherein one of the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 is loose; or when the vehicle 200 is stationary, one of the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 is loose. In other words, as long as either the first area 211 of the vehicle 200 or the second area 212 of the vehicle 200 is loose, it indicates that the two are in relative movement.

[0086] Accordingly, the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 are relatively stationary, which means that no matter the vehicle 200 is driving normally or the vehicle 200 is stationary, the position between the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 will not change.

[0087] In some embodiments, the sensing element 130 may be a sensor.

[0088] It should be noted that in the loosening monitoring of automobile parts, the detection component 100 is installed in a position where the parts may come into contact and collide with other parts when the parts become loose. When the two parts collide or rub, the first detection member 110 and the first detection member 110 will produce a charge change, thereby generating an electrical signal. By monitoring and analyzing these electrical signals, it is possible to monitor in real time whether the parts of the vehicle 200 come into contact and collide during driving, as well as the degree and frequency of the collision.

[0089] It should be noted that the component can be applied to various types of vehicles 200, whether passenger cars, commercial vehicles or special vehicles 200, and has wide applicability.

[0090] Through the above-mentioned settings, that is, through the settings of the first detection member 110, the first detection member 110 and the sensing member 130, the relative movement between different areas of the vehicle 200 can be monitored in real time, and the degree and position of the looseness can be accurately determined through the change of the electrical signal, thereby improving the accuracy of the detection, timely discovering the looseness problem, and performing maintenance and repairs at an early stage to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle 200; in addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals at the early stage of component loosening; in addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy, and does not require a battery for power supply. When the first detection member 110 and the first detection member 110 contact and collide with each other, a signal can be transmitted to provide a self-powered function for the sensing member 130, without the need for an external power supply.

[0091] Continue to refer Figures 1 to 6 In some optional embodiments, at least one of the first detection member 110 and the second detection member 120 is a flexible member.

[0092] It is understood by those skilled in the art that the flexible parts can adapt to the shapes and motion characteristics of different areas of the vehicle 200, especially on complex or irregular surfaces, to ensure that the detection assembly 100 can fit tightly and accurately detect looseness. In addition, the flexible parts are generally lighter than rigid parts, which helps to reduce the overall weight of the vehicle 200, thereby improving fuel efficiency and vehicle 200 performance.

[0093] It should be noted that the use of flexible parts makes the installation of the detection component 100 more flexible, able to adapt to the design requirements of different vehicles 200, and simplify the installation process; the flexible parts are not easy to break when impacted by external forces, reducing the potential risk of damage to other components of the vehicle 200 and improving the safety of the overall system.

[0094] Continue to refer Figures 1 to 6 In some optional embodiments, the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 are arranged opposite to each other, and there is a first gap between the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200;

[0095] When the first gap increases or decreases, an electrical signal is generated between the first detecting member 110 and the first detecting member 110 .

[0096] It can be understood by the technical personnel of the present application that by detecting the change in the first gap, the looseness or tightness of the structure of the vehicle 200 components can be sensitively sensed, and the electrical signal caused by the gap change can be transmitted to the sensing element 130 in real time, providing instant feedback information, so that the vehicle 200 operator or maintenance personnel can take quick measures, which helps to detect potential problems at an early stage.

[0097] It should be noted that when the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 are relatively stationary, the first gap remains unchanged; when the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 move relatively, the first gap changes, that is, becomes larger or smaller.

[0098] In some embodiments, the first detection member 110 and the second detection member 120 are arranged opposite to each other with a second gap therebetween, wherein, in order to improve the accuracy of detection, the first detection member 110 may be arranged in the first area 211 of the vehicle 200 and facing the side of the second area 212 of the vehicle 200, and correspondingly, the second detection member 120 may be arranged in the second area 212 of the vehicle 200 and facing the side of the first area 211 of the vehicle 200. The second gap may be smaller than the first gap.

[0099] In other embodiments, considering the actual situation of the vehicle 200, the first detection member 110 and the second detection member 120 may not be arranged opposite to each other, depending on which two parts of the vehicle need to be detected for looseness.

[0100] Continue to refer Figures 1 to 6 In some optional embodiments, the first detection member 110 includes a first friction layer 111 and a first electrode layer 112, the first friction layer 111 is disposed on the first region 211 of the vehicle 200, and the first electrode layer 112 is disposed on the first friction layer 111;

[0101] The second detection member 120 includes a second friction layer 121 and a second electrode layer 122, wherein the second friction layer 121 is disposed on the second region 212 of the vehicle 200, and the second electrode layer 122 is disposed on the second friction layer 121, wherein the electrical properties of the first friction layer 111 and the second friction layer 121 are different;

[0102] When the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 move relative to each other, the first friction layer 111 and the second friction layer 121 contact or separate from each other, so that an electrical signal is generated between the first electrode layer 112 and the second electrode layer 122 .

[0103] It is understood by the technical personnel of the present application that by utilizing the triboelectric effect, an electrical signal can be generated when two areas move relative to each other. Since the triboelectric effect is very sensitive to contact and separation, the system can detect small relative movements and gap changes, thereby achieving highly sensitive looseness detection. In addition, it also provides a possibility of self-powering, reducing the dependence on external power supply.

[0104] It should be noted that since triboelectric materials and electrode materials are generally low in cost, this design can achieve efficient looseness detection at a lower cost.

[0105] In some embodiments, the detection component 100 uses two materials with different triboelectric properties as friction layers, and forms nano friction layers after surface microstructure treatment, namely: a first friction layer 111 and a second friction layer 121. The first friction layer 111 and the second friction layer 121 are cut into long strips to ensure their flatness and uniformity, and to remove impurities and contaminants on the surface.

[0106] Next, a first electrode layer 112 is prepared on one side of the first friction layer 111. The first electrode in the first electrode layer 112 is made of a metal material with excellent conductivity, such as a copper electrode or an aluminum electrode. Next, the first electrode layer 112 is adsorbed on the surface of the first friction layer 111 by vacuum evaporation or sputtering.

[0107] Similarly, the second electrode layer 122 can be seen above.

[0108] Figure 7 A theoretical model of a detection component provided in an embodiment of the present application, such as Figure 7 As shown, it should be noted that the electron cloud potential well model can well explain the problem of electron transfer during the operation of the device. When two materials are in contact with each other, when the distance between atoms is less than the normal bonding length in the repulsive region, due to the reduction of the interatomic potential barrier, a strong electron cloud overlap is formed between the two atoms or molecules, which will cause the electrons between the atoms or molecules to transition. Generally speaking, electrons are transferred from one material to another, causing the materials to carry different charges, thereby forming a friction electrification phenomenon. Since the external force of contact and friction induces a strong overlap between the electron clouds, this external force makes it easier for electron transfer between materials to occur.

[0109] Figure 8 A working principle diagram of a detection component provided in an embodiment of the present application, such as Figure 8As shown, it should be noted that the specific working principle of the detection component 100 is: when the first detection member 110 and the second detection member 120 are respectively pasted on the surfaces of two adjacent components. When the first detection member 110 and the second detection member 120 are placed face to face, that is, when the two components do not come into contact or collide, the entire detection component 100 is in a static state, and no potential difference is generated. When one of the components becomes loose and collides and contacts with the adjacent component (i), the first friction layer 111 and the second friction layer 121 will be in close contact. Due to the different attraction and binding abilities of the two materials for electrons, the positive charge will be transferred from the material with stronger electronegativity to the material with weaker electronegativity. In this way, equal amounts of opposite charges will be formed on the two contact surfaces, that is, the surface of one material is positively charged and the surface of the other material is negatively charged.

[0110] During the movement of the car, the loose parts are in a state of constant collision-separation. When the parts are in a separated state (ii), the friction layer they carry begins to separate, and a small air gap is formed in the middle. Due to the effect of electrostatic induction, a potential difference is formed between the first electrode layer 112 and the second electrode layer 122 plated on the back of the first friction layer 111 and the second friction layer 121. At this time, driven by the potential difference, electrons flow from the first electrode layer 112 to the second electrode layer 122 through the load of the two connected electrodes, thereby forming a current. As the separation distance continues to increase, the potential difference between the first electrode layer 112 and the second electrode layer 122 will continue to increase until it reaches a maximum value (iii).

[0111] When the components are in the state of separation to collision again (iiii), the potential difference between the first electrode layer 112 and the second electrode layer 122 will gradually disappear, the electrostatic field formed previously will change, and the electrons that previously flowed to the other electrode through the load will flow back to the original electrode until the first friction layer 111 and the second friction layer 121 completely overlap and return to the initial state. At this time, the induced charges on the first electrode layer 112 and the second electrode layer 122 are all neutralized, and the potential difference is zero.

[0112] Fig. 9 An electrical signal waveform diagram of a detection component provided in an embodiment of the present application, such as Fig. 9 As shown, when two components are in a loose state and the first friction layer 111 and the second friction layer 121 are constantly in a contact and separation state, an alternating current will be generated in the external circuit. Therefore, we can determine whether the components are loose and the degree of looseness by detecting the electrical signal output by the component 100.

[0113] like Fig. 9As shown, when the frequency is constant but the amplitude becomes larger, it means that the contact area between the first friction layer 111 and the second friction layer 121 becomes larger, the amount of transferred charge increases, and the impact between the two components becomes more serious.

[0114] At the same time, the detection component 100 has obvious advantages over traditional detection devices. Once the sensor in the traditional detection device has a problem with the power supply, the sensor will not work. The detection component 100 of the present application can convert mechanical energy into electrical energy to provide energy for its own sensing function, is not limited by the external power supply, ensures that the component can continue to operate, reduces monitoring interruptions caused by sensor energy exhaustion, and improves the reliability and stability of the detection component 100.

[0115] In some embodiments, the sensing element 130 may be a processor. Regarding the workflow between the detection component 100 and the processor, the detection component 100 monitors whether two components collide. When a collision occurs, a corresponding electrical signal is generated. The signal at this time is relatively weak and noisy, so the signal needs to be filtered and processed to make it suitable for subsequent transmission; the processed signal enters the analog-to-digital converter to convert the analog signal into a digital signal; after receiving the digital signal, the processor analyzes, calculates and processes the data and finally makes a decision, such as displaying the data on a display screen.

[0116] In some optional embodiments, the first detection member 110 further includes a first base layer 113, the first base layer 113 has a first adhesive surface and a second adhesive surface, the first adhesive surface is attached to the surface of the first area 211 of the vehicle 200, the first friction layer 111 is attached to the second adhesive surface, and the first electrode layer 112 is attached between the first friction layer 111 and the second adhesive surface; and / or,

[0117] The second detection member 120 also includes a second base layer 123, the second base layer 123 has a third adhesive surface and a fourth adhesive surface, the third adhesive surface is attached to the surface of the second area 212 of the vehicle 200, the second friction layer 121 is attached to the fourth adhesive surface, and the second electrode layer 122 is attached between the second friction layer 121 and the fourth adhesive surface.

[0118] It can be understood by the technicians of the present application that by adding the first base layer 113 and the second base layer 123, the overall structure of the detection assembly 100 is more stable, and can better resist external vibration and impact, thereby ensuring the reliability of detection. The first base layer 113 and the second base layer 123 provide adhesive surfaces, so that the first detection member 110 and the second detection member 120 can be conveniently installed on different areas of the vehicle 200, ensuring the correct positioning and function realization of the friction layer and the electrode layer.

[0119] It should be noted that by ensuring stable contact between the friction layer and the electrode layer, the first base layer 113 and the second base layer 123 help improve the accuracy and consistency of the detection signal, thereby more accurately reflecting the relative movement between the areas of the vehicle 200. The component has the advantages of light weight, low cost, and easy production.

[0120] In some embodiments, the design of the first base layer 113 and the second base layer 123 can be adjusted according to the specific structure of the vehicle 200 to adapt to different installation positions and surface characteristics, thereby improving the applicability of the components.

[0121] In some optional embodiments, at least one of the first base layer 113 and the second base layer 123 is an adhesive-backed member.

[0122] It can be understood by the technicians of the present application that the design of the adhesive backing allows the detection component 100 to be directly adhered to the designated area of ​​the vehicle 200 without the need for additional fixing devices or tools, thereby simplifying the installation process and saving time and manpower; the adhesive backing usually has excellent adhesion properties and can be firmly fixed to the surface of the vehicle 200, ensuring that the detection component 100 remains stable during the operation of the vehicle 200 and is not easy to fall off.

[0123] The adhesive backing can adapt to the slight unevenness or curve of the surface of the vehicle 200, so that the detection assembly 100 can be reliably installed under various surface conditions. The adhesive backing is usually light, which helps to reduce the overall weight of the detection assembly 100 and has little impact on the performance of the vehicle 200. The adhesive backing material can be selected to have the characteristics of high temperature resistance, moisture resistance and chemical corrosion resistance to ensure the reliability of the detection assembly 100 under various environmental conditions.

[0124] In addition, it should be noted that the component has a small thickness and can be adhered to the outer surface of the vehicle 200 parts using a 3M adhesive backing layer, and the length can be cut according to the size of the parts, so it can adapt to the complex structure and shape of the vehicle 200.

[0125] In some embodiments, the overall structure of the detection component 100 is cut into a long strip, and the cuttable function is achieved by designing the shape of the first electrode in the first electrode layer 112 and the second electrode in the second electrode layer 122 .

[0126] Exemplarily, the first electrode is an A electrode, and the second electrode is a B electrode.

[0127] Taking the first electrode as electrode A as an example, adjacent metal electrodes are connected by a narrower piece of the same metal material to form a cutting point. Since the entire electrode structure is made of metal material, its conductive properties will not change and it has uniformity and consistency. Therefore, when cutting at the cutting point, the remaining conductive circuit can still maintain a good connection.

[0128] Fig.10 A schematic diagram of the structure of the first base layer in a detection component provided in an embodiment of the present application, such as Fig.10 As shown, a corresponding groove 1131 structure is designed on the side where the first base layer 113 is attached to the component. When cutting according to the groove 1131 structure, the device is cut exactly at the middle part between adjacent electrodes. The device is long and has a soft overall structural material, which can be adapted to components with curved surfaces. During installation, it can also be freely cut according to the size of the component to achieve a flexible and deformable function.

[0129] In some optional embodiments, one of the materials of the first friction layer 111 and the second friction layer 121 is a high molecular polymer, and the other is a high molecular compound.

[0130] It is understood by the skilled person in the present application that since polymers and polymer compounds have different electrical properties, when they come into contact or separate from each other, a significant triboelectric effect will be generated. This material combination can enhance the generation of electrical signals and improve the sensitivity and accuracy of detection.

[0131] It should be noted that high molecular polymers and high molecular compounds generally have good mechanical properties and chemical stability, and can maintain stable performance under different environmental conditions, thereby ensuring the long-term reliability of the detection component 100. High molecular materials are generally light, which helps to reduce the overall weight of the detection component 100, thereby having less impact on the performance of the vehicle 200.

[0132] Polymers are large molecular compounds composed of repeating units. They are formed by many monomer molecules connected by polymerization. During the polymerization process, double bonds or other active groups in the monomer molecules are opened to form new chemical bonds, thus connecting the monomers together to form a polymer chain. Polymerization reactions can be carried out by different chemical methods, such as addition polymerization, condensation polymerization, and ring polymerization.

[0133] In some optional embodiments, the first friction layer 111 is made of polytetrafluoroethylene; and / or,

[0134] The material of the second friction layer 121 is polyhexamethylene terephthalamide.

[0135] It is understood by those skilled in the art that polytetrafluoroethylene and polyhexamethylene terephthalamide have different electrical properties, and when they are in contact or separated from each other, a significant triboelectric effect will be generated. This material combination can effectively generate an electrical signal for detecting relative movement between regions of the vehicle 200.

[0136] It should be noted that the first friction layer 111 is formed by subjecting the film made of polytetrafluoroethylene to surface microstructure treatment, and the first electrode A in the first electrode layer 112 is adsorbed on the surface of the first friction layer 111 by vacuum evaporation or sputtering; finally, the first electrode layer 112 and the first friction layer 111 are attached to the first base layer 113 to form the first detection member 110. Since both sides of the first base layer 113 are sticky, one side is bonded to the first electrode layer 112, and the other side is bonded to the outer surface of the component.

[0137] The second friction layer 121 is formed by treating the surface microstructure of a film made of poly(hexamethylene terephthalamide), and the second electrode B in the second electrode layer 122 is adsorbed on the surface of the second friction layer 121 by vacuum evaporation or sputtering. Finally, the second electrode layer 122 and the second friction layer 121 are attached to the second base layer 123 to form the second detection element 120. Since both sides of the second base layer 123 are sticky, one side is bonded to the second electrode layer 122, and the other side is bonded to the outer surface of the component.

[0138] Then, the first detection member 110 and the second detection member 120 are respectively bonded to the positions where the two components are prone to collision.

[0139] Fig.11 A schematic diagram of the structure of another detection component provided in an embodiment of the present application, such as Figure 2 , Fig.11 As shown, in some optional embodiments, the first detection member 110 is a first magnetic member 1101 and a Hall chip 1102, and the second detection member 120 is a second magnetic member 1201;

[0140] When the first area 211 of the vehicle 200 and the second area 212 of the vehicle 200 move relative to each other, the Hall chip 1102 generates an electrical signal according to the change of the magnetic field between the first magnetic member 1101 and the second magnetic member 1201 .

[0141] It is understood by the technicians of the present application that the Hall chip 1102 can accurately detect small changes in the magnetic field, and thus can sensitively sense the relative movement between the first area 211 and the second area 212 of the vehicle 200. This high sensitivity helps to find looseness or displacement problems in a timely manner. The Hall effect sensor can quickly respond to changes in the magnetic field and provide real-time electrical signal output, so that the system can immediately feedback changes in the state of the vehicle 200.

[0142] It should be noted that the Hall chip 1102 is a semiconductor magnetoelectric device that works using the Hall effect. The Hall effect refers to the phenomenon that when current passes through a conductor in a magnetic field, a potential difference is generated on both sides of the conductor. The Hall chip 1102 uses this effect to detect changes in the magnetic field and converts it into an electrical signal output. In terms of position detection, the Hall chip 1102 can be used to detect the position and movement of an object.

[0143] The Hall chip 1102 is a sensor chip based on the Hall effect principle, which can be used to measure the strength and direction of the magnetic field. It consists of a Hall element, a signal conditioning circuit and a digital output interface.

[0144] The Hall effect is a potential difference phenomenon generated by a magnetic field, and the magnetic field signal can be converted into an electrical signal through a Hall element. The Hall element in the Hall chip 1102 is usually made of semiconductor materials, such as silicon, gallium, etc. When the magnetic field is perpendicular to the surface of the Hall element, the magnetic field will deflect the electrons, thereby separating the positive and negative charges and forming a potential difference. The signal conditioning circuit can amplify, filter and stabilize this potential difference, and finally output a stable voltage signal.

[0145] Exemplarily, the first area 211 of the vehicle 200 becomes loose, the first magnetic part 1101, the second magnetic part 1201 and the Hall chip 1102 are in a triangular relative position relationship, and the magnetic field generated by the first magnetic part 1101 changes with the movement of the first area 211 of the vehicle 200 under the influence of the second magnetic part 1201. The Hall chip 1102 generates an electrical signal according to the change in the magnetic field generated by the first magnetic part 1101, and the electrical signal is used to indicate the position change of the first area 211 of the vehicle 200.

[0146] The specific working principle of the Hall sensor device of this embodiment is: when the first area 211 of the vehicle 200 moves from the first position to the second position, the magnetic resistance of the working magnetic circuit where the Hall chip 1102 is located is significantly increased or decreased, that is, the magnetic lines of force passing through the Hall chip 1102 are significantly reduced or increased, and the Hall chip 1102 can detect the position change of the first area 211 of the vehicle 200 through the change of the magnetic field strength.

[0147] Furthermore, the shapes of the first magnetic member 1101 and the second magnetic member 1201 include but are not limited to a cuboid, a cube, a cylinder or a regular n-gonal three-dimensional structure, wherein n≥5.

[0148] Furthermore, the second magnetic member 1201 is a magnetic conductor or a magnet to adapt to different magnetic field change requirements.

[0149] Further, when the second magnetic member 1201 is a magnetic conductor, the S pole of the first magnetic member 1101 is close to the second magnetic member 1201. When the second magnetic member 1201 is a magnet, the end of the magnet close to the Hall chip 1102 is the N pole, and the end away from the Hall chip 1102 is the S pole.

[0150] The detection component provided in the embodiment of the present application includes: a first detection member, which is arranged in a first area of ​​the vehicle; a second detection member, which is arranged in a second area of ​​the vehicle, the first detection member and the second detection member are arranged relative to each other, and when the first area of ​​the vehicle and the second area of ​​the vehicle move relative to each other, an electrical signal is generated between the first detection member and the first detection member; and a sensing member, which is used to receive the electrical signal to issue an alarm signal.

[0151] By setting up the first detection member, the first detection member and the sensing member, the relative movement between different areas of the vehicle can be monitored in real time. Through the change of the electrical signal, the degree and position of the looseness can be accurately determined, the accuracy of the detection can be improved, and the looseness problem can be discovered in time. Maintenance and repairs can be carried out in the early stages to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle; in addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals in the early stages of component loosening; in addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy, and does not require a battery for power supply. When the first detection member and the first detection member contact and collide with each other, they can transmit signals, providing a self-powered function for the sensing member without the need for an external power supply.

[0155] The vehicle provided in the embodiment of the present application can monitor the relative movement between different areas of the vehicle in real time through the arrangement of the first detection member, the first detection member and the sensing member. The degree and position of the looseness can be accurately determined through the change of the electrical signal, thereby improving the accuracy of the detection, timely discovering the looseness problem, and performing maintenance and repairs at an early stage to prevent potential safety hazards, thereby reducing the maintenance and repair costs of the vehicle. In addition, the component can have a high sensitivity to tiny vibrations and displacements, and can detect abnormal signals in the early stages of component loosening. In addition, the component has a self-powered function, which can convert the mechanical energy of vibration into electrical energy without the need for a battery for power supply. When the first detection member and the first detection member contact and collide with each other, a signal can be transmitted, thereby providing a self-powered function for the sensing member without the need for an external power supply.
