Description

Technical Field

[0001] This utility model relates to the field of glass technology, specifically to glass components and carriers having the same. Background Technology

[0002] The anti-pinch function of car door windows is crucial to the safety of drivers and passengers. The core objective of the anti-pinch function is to immediately stop the window from rising and reverse its direction when an obstacle, such as a hand or other object, is detected during the window's ascent, thus preventing injury or damage.

[0003] Existing anti-pinch technology achieves its function by setting capacitive pressure sensors on the inside and outside of the car door glass. The principle is based on the characteristic that the capacitance value changes with the electrode spacing / medium. When a human or object touches the glass and applies pressure, it will squeeze the electrodes of the sensor or change the medium between the electrodes, causing a sudden change in the capacitance value. After the system detects this change, it triggers the glass to stop or reverse.

[0004] However, the core parameter (capacitance value) of capacitive sensors is easily affected by external environmental media, humidity, and temperature. Since car door glass is in an open / semi-open environment with complex environmental variables, it directly leads to poor stability of the anti-pinch function, which in turn causes false triggering or missed triggering. Utility Model Content

[0005] In view of this, the present invention provides a glass component and a carrier having the same, in order to solve the problem of high misjudgment rate of anti-pinch glass in the prior art.

[0006] In a first aspect, the present invention provides a glass assembly, comprising: a glass body, the glass body including opposing first side surfaces and second side surfaces, and an edge surface connecting the first side surface and the second side surface, wherein a groove is provided along at least a portion of the edge surface; and a pressure sensor assembly, the pressure sensor assembly covering at least a portion of the edge surface, the pressure sensor assembly including a resistance detection layer and a connecting layer, wherein at least a portion of the connecting layer is disposed within the groove.

[0007] The glass body includes a first side and a second side, the first side being the inner side of the vehicle and the second side being the outer side of the vehicle. An edge surface connecting the first and second side surfaces is a surface along the thickness direction of the glass body. A groove is provided on at least a portion of the edge surface, providing mounting space for a pressure sensor assembly. At least a portion of the pressure sensor assembly is located within the groove, allowing the pressure sensor assembly to connect with the groove, effectively fixing the pressure sensor assembly and improving its structural stability.

[0008] Another part of the pressure sensor assembly covers at least a portion of the edge surface, such that at least a portion of the pressure sensor assembly is directly located on the surface of the glass body in the thickness direction. This allows the pressure sensor assembly to directly contact an obstacle (human body or object) when the glass body rises to close the window, provided that the obstacle is located in the rising path of the glass body. The force generated by the obstacle acts directly on the pressure sensor assembly, reducing the force transmission path, improving the response speed, and thus enhancing detection accuracy and consistency.

[0009] In one optional embodiment, the glass body has a first edge, a second edge, and a third edge, with the second and third edges located on opposite sides of the first edge. The groove includes a first groove, a second groove, and a third groove. The first groove is disposed on the first edge and covers it. The second groove is disposed on the second edge and covers at least a portion of it. The third groove is disposed on the third edge and covers at least a portion of it. This arrangement ensures that pressure sensor components are installed in all areas where there is a gap between the glass body and the outer frame of the window during the glass body's ascent, covering the entire operating path of the glass body. This avoids detection blind spots, prevents missed triggering in some areas, and further enhances the accuracy and consistency of the detection.

[0010] In one alternative embodiment, the first edge is arc-shaped, the glass body further includes a fourth edge, one end of the second groove is connected to one end of the first groove, the other end of the second groove has a first gap with the fourth edge, and / or; one end of the third groove is connected to the other end of the first groove, the other end of the third groove has a second gap with the fourth edge. The gaps facilitate the routing of wires from the pressure sensor assembly.

[0011] In one optional embodiment, a wire is connected to the resistance detection layer. One end of the wire extends from the first gap between the second groove and the fourth edge, and the other end extends from the second gap between the third groove and the fourth edge. The wire is used to connect to the control module. By leading the wire from the groove to the gap and then passing it close to the glass surface, it does not protrude from the glass edge, ensuring that the wire is not broken or worn when the glass body is raised or lowered.

[0012] In an optional embodiment, the pressure sensor assembly further includes an encapsulation layer comprising: a first encapsulation portion covering an edge surface; and a second encapsulation portion connected to the first encapsulation portion and used for connection with a groove. The first and second encapsulation portions together form a receiving cavity, and the first and second encapsulation portions are perpendicularly disposed in the cross-section of the encapsulation layer. The encapsulation layer protects the internal resistance detection layer and connection layer, preventing the resistance detection layer from being affected by environmental factors such as humidity changes, dust, and rain, thus ensuring the effectiveness of the anti-pinch function.

[0013] In one optional embodiment, the connecting layer includes: a cover portion located within a first encapsulation portion; and an extension portion connected to the cover portion and located within a second encapsulation portion. In the cross-section of the connecting layer, the cover portion and the extension portion are perpendicularly disposed. This arrangement divides the connecting layer into a cover portion and an extension portion according to the structure of the groove. The extension portion serves a fixing function, and the connection between the cover portion and the extension portion provides support for the resistance detection layer.

[0014] In one optional embodiment, the resistance detection layer includes: an electrode layer located within the first encapsulation portion and on the surface of the cover portion, connected to a wire; and a piezoresistive sensitive layer located within the first encapsulation portion and on the surface of the electrode layer, electrically connected to the electrode layer. The piezoresistive sensitive layer senses the pressure exerted by an obstacle on the glass body, causing a change in the conductive path within the piezoresistive sensitive layer, thereby generating a resistance change signal. The electrode layer transmits the resistance change signal (corresponding to the pressure value) to the input terminal of the control module via a wire. When the glass body is in operation, if the control module detects that the pressure value and duration have reached a preset value, the control module drives the lifting motor to reverse, causing the glass body to descend a certain distance, thus achieving anti-pinch protection.

[0015] In one alternative embodiment, the connecting layer is made of PET film, and / or; the encapsulation layer is made of transparent epoxy resin, and / or; the electrode layer is made of ITO film, and / or; and the piezoresistive sensing layer is made of graphene composite material. This enables the pressure sensor assembly to possess ultra-high sensitivity, accurately identify minute pressures, avoid missed detections due to clamping, and maintain light transmittance to ensure aesthetics.

[0016] In one optional embodiment, the glass body includes: an inner glass layer; an outer glass layer, with a PVB layer disposed between the inner and outer glass layers, and a groove disposed at the edge of the PVB layer. This arrangement ensures the sealing of the glass assembly with the external structure and also guarantees the appearance integrity of the glass.

[0017] Secondly, the present invention also provides a carrier, which includes the aforementioned glass assembly.

[0018] Since the vehicle includes glass components and has the same effect as glass components, it will not be described in detail here. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0026] In some related technologies, pressure sensors are usually installed on the window regulator, or on the top of the door trim panel, or inside the sealing strip along the upper edge of the glass. When the glass comes into contact with an obstacle, the obstacle exerts a reaction force on the glass. The pressure value detected by the pressure sensor will quickly exceed the anti-pinch threshold. After the system detects that the threshold has been exceeded, it triggers the glass to stop or reverse.

[0027] However, placing the pressure sensor on the window regulator results in a long force transmission path, leading to prolonged sensing hysteresis. This results in slow response, poor accuracy and consistency, and susceptibility to the condition of the window mechanism. Furthermore, placing the pressure sensor on the top of the door trim panel or within the sealing strip presents drawbacks such as high crosstalk, susceptibility to installation and aging, indirect measurement, and a high risk of false or missed triggering due to environmental factors.

[0028] In other related technologies, capacitive pressure sensors are placed on the inner and outer sides of the glass. Utilizing the characteristic that capacitance changes with the electrode spacing / medium, when a person or object comes into contact with the glass and applies pressure, it squeezes the sensor electrodes or changes the medium between the electrodes, causing a sudden change in capacitance. The system detects this change and triggers the glass lifting mechanism to stop or reverse. However, this technology has the following drawbacks: In rainy weather, after a car wash, or in high-humidity environments, moisture can adhere to the glass surface. If moisture seeps into the sensor due to sealing issues, it directly alters the dielectric environment between the electrodes, causing an abnormal increase in capacitance. The system might misinterpret this as pressure from an object, triggering the glass to stop / reverse unexpectedly, resulting in a false trigger. Conversely, if moisture evenly covers the sensor, it may mask the capacitance change caused by actual pressure. For example, a light touch with a finger can have a much greater dielectric effect than pressure, leading to a missed trigger.

[0029] There are numerous electromagnetic sources inside a car, such as motors, central control systems, and wireless charging modules. The window regulator motors near the door windows are strong sources of electromagnetic interference. The electrodes of capacitive sensors are essentially tiny capacitors, which are susceptible to stray capacitance induced by external electromagnetic fields. This causes fluctuations in capacitance values, which are difficult to distinguish from capacitance changes caused by pressure, directly leading to false triggering or missed triggering.

[0030] It should be noted that the glass assembly of this application is applied to the side window of a vehicle. Those skilled in the art can also make adaptive modifications to apply it to the sunroof of a vehicle, or other applications.

[0031] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, in one aspect, a glass assembly is provided. For example... Figure 1 As shown, the glass assembly includes a glass body 10 and a pressure sensor assembly 20. The glass body 10 includes opposing first side surfaces 11 and second side surfaces 12, and an edge surface 13 connecting the first side surfaces 11 and second side surfaces 12. A groove 14 is provided along at least a portion of the edge surface 13. The pressure sensor assembly 20 covers at least a portion of the edge surface 13 and includes a resistance detection layer 21 and a connecting layer 22. At least a portion of the connecting layer 22 is disposed within the groove 14.

[0033] In this embodiment, the glass body 10 is used to install on the side window of a vehicle. Those skilled in the art can also install it on the sunroof of a vehicle.

[0034] The glass body 10 includes a first side surface 11 and a second side surface 12, with the first side surface 11 being the inner side of the vehicle and the second side surface 12 being the outer side of the vehicle. An edge surface 13 connecting the first side surface 11 and the second side surface 12 is a surface along the thickness direction of the glass body 10. A groove 14 is provided on at least a portion of the edge surface 13, providing mounting space for the pressure sensor assembly 20. At least a portion of the pressure sensor assembly 20 is located within the groove 14, allowing the pressure sensor assembly 20 to connect with the groove 14, effectively fixing the pressure sensor assembly 20 and improving its structural stability.

[0035] In addition, the inner wall of the groove 14 is roughened to enhance the bonding force between the groove 14 and the pressure sensor assembly 20 and improve the connection stability of the pressure sensor assembly 20.

[0036] Another portion of the pressure sensor assembly 20 covers at least a portion of the edge surface 13, such that at least a portion of the pressure sensor assembly 20 is directly located on the surface of the glass body 10 in the thickness direction. This allows the pressure sensor assembly 20 to directly contact an obstacle (human body or object) in the rising path of the glass body 10 when the glass body 10 is raised to close the window. The force generated by the obstacle acts directly on the pressure sensor assembly 20, reducing the force transmission path, improving the response speed, and thus enhancing detection accuracy and consistency.

[0037] It should be noted that the glass body 10 includes an inner glass layer 101 and an outer glass layer 102, with a PVB layer 103 between the inner glass layer 101 and the outer glass layer 102. A groove 14 is disposed at the edge of the PVB layer 103. The aforementioned edge surface 13 is composed of the edge of the inner glass layer 101, the edge of the outer glass layer 102, and the edge of the PVB layer 103. The groove 14 is disposed at the edge of the PVB layer 103, with part of the pressure sensor assembly 20 located within the groove 14 and the other part located on the edge surface 13. The width direction of the other part of the pressure sensor assembly 20 is arranged along the edges of the inner glass layer 101, the PVB layer 103, and the outer glass layer 102. This arrangement increases the contact area between the glass body 10 in the thickness direction (i.e., the edge surface 13) and the pressure sensor assembly 20, thereby ensuring the detection accuracy of the pressure sensor assembly 20.

[0038] Furthermore, the pressure sensor assembly 20 includes a resistance detection layer 21 and a connecting layer 22. The resistance detection layer 21 detects changes in resistance with deformation / stress under the pressure of an obstacle, inferring the pressure magnitude by detecting the resistance change. The connecting layer 22 is connected to the resistance detection layer 21, with at least a portion of the connecting layer 22 located within the groove 14 and another portion extending outside the groove 14 and located on the edge surface. The resistance detection layer 21 is located on the surface of the connecting layer 22. The connecting layer 22 provides support and a placement platform for the resistance detection layer 21, allowing it to directly contact the obstacle pressure, further improving the detection speed and accuracy of the resistance detection layer 21.

[0039] Compared to existing capacitive pressure sensors that require precise parallel plates and have high manufacturing costs, this application uses a piezoresistive pressure sensor, which has a simpler structure and lower costs. Furthermore, existing capacitive pressure sensors are affected by environmental factors such as humidity and temperature, as well as electromagnetic radiation. In contrast, the resistive detection layer 21 of this application is only sensitive to pressure, exhibiting strong anti-interference capabilities and more stable pressure detection. In other words, this application comprehensively improves the detection accuracy and consistency of the pressure sensor assembly 20 by selecting the setting location, installation method and type of the pressure sensor, reduces the response time, reduces the false judgment rate of anti-pinch, improves the safety of use, achieves the technical effect of stable glass anti-pinch, and solves the problem of high false judgment rate of anti-pinch glass in the prior art.

[0040] like Figure 2 As shown, the glass body 10 has a first edge 15, a second edge 16, and a third edge 17. The second edge 16 and the third edge 17 are located on both sides of the first edge 15. The first edge 15 is arc-shaped to fit the edge of the window. The second edge 16 and the third edge 17 are arranged parallel to each other, and the length of the second edge 16 is less than the length of the third edge 17. The second edge 16 and the third edge 17 are straight.

[0041] In some embodiments not shown, the shape of the first edge 15 is not limited to this, and may also be straight to fit the shape of the front door triangular window.

[0042] In some embodiments not shown, the second edge 16 and the third edge 17 may also be configured as arcs.

[0043] like Figure 2 , Figure 3 , Figure 4 As shown, the groove 14 includes a first groove 141, a second groove 142, and a third groove 143. The first groove 141 is disposed on the first edge 15 and covers the first edge 15. The second groove 142 is disposed on the second edge 16 and covers at least a portion of the second edge 16. The third groove 143 is disposed on the third edge 17 and covers at least a portion of the third edge 17. Pressure sensor assemblies 20 are disposed within each of the first, second, and third grooves 141 and 142. This arrangement ensures that pressure sensor assemblies 20 are placed in all areas where there is a gap between the glass body 10 and the window frame during the upward movement of the glass body 10, covering the entire running path of the glass body 10. This avoids detection blind spots, prevents missed triggering in some areas, and further enhances the accuracy and consistency of detection.

[0044] Furthermore, the glass body 10 also includes a fourth edge 18, one end of the second groove 142 is connected to one end of the first groove 141, the other end of the second groove 142 has a first gap 181 with the fourth edge 18, and / or; one end of the third groove 143 is connected to the other end of the first groove 141, the other end of the third groove 143 has a second gap 182 with the fourth edge 18. The fourth edge 18 is disposed opposite to the first edge 15, the second groove 142 has a first gap 181 with the fourth edge 18, and the third groove 143 has a second gap 182 with the fourth edge 18. That is to say, there is no groove structure at the first gap 181 corresponding to the second edge 16, that is, there is no pressure sensor assembly 20 at the first gap 181 of the second edge 16, and there is no groove structure at the second gap 182 corresponding to the third edge 17, that is, there is no pressure sensor assembly 20 at the second gap 182 of the third edge 17. The gap setting facilitates the lead-out of the wire of the pressure sensor assembly 20.

[0045] Meanwhile, since the second edge 16, the third edge 17, and the fourth edge 18 of the glass body 10 are the core stress-bearing areas of the glass body 10, the corners of the glass body 10, namely the areas of the first gap 181 and the second gap 182, are weak in stress. By reserving gaps (without setting grooves at the gaps), the glass body 10 is prevented from being prone to cracking at the grooves due to the friction of the guide rail and the pulling force of the lifter during lifting, thus protecting the safety of the glass body.

[0046] In this embodiment, the fourth edge 18 has an irregular shape. In other embodiments, the fourth edge 18 can be a straight line or an arc.

[0047] Furthermore, a wire 30 is connected to the resistance detection layer 21. One end of the wire 30 extends from the first gap 181 between the second groove 142 and the fourth edge 18, and the other end extends from the second gap 182 between the third groove 143 and the fourth edge 18. The wire 30 is used to connect to the control module. By leading the wire 30 from the groove to the gap and then passing it close to the glass surface, it will not protrude from the glass edge, ensuring that the wire is not broken or worn when the glass body 10 is raised or lowered.

[0048] Specifically, the resistance sensing layer 21 includes an electrode layer 211 and a piezoresistive sensitive layer 212. The piezoresistive sensitive layer 212 is electrically connected to the electrode layer 211. When the glass is squeezed, the resistance value of the piezoresistive sensitive layer 212 changes significantly with the stress. The electrode layer 211 and the piezoresistive sensitive layer 212 are tightly electrically connected, usually through conductive adhesive or direct contact, which can transmit the resistance change signal to the wire 30.

[0049] In this embodiment, the electrode layer 211 is designed as an interdigitated electrode, which has a larger contact area with the piezoresistive sensitive layer 212 and is more uniformly distributed.

[0050] In other embodiments, the electrode layer 211 is designed as a comb-like structure.

[0051] When pressure is applied to different locations on the glass body 10, the resistance change of the piezoresistive sensitive layer 212 can be quickly collected by the nearby electrode layer 211, avoiding local signal loss due to uneven electrode contact. For example, when pressure is applied to different points along the upper edge of the car window glass, this structure ensures that the resistance change at each point can be captured and conducted by the electrode layer 211, ensuring full-area coverage of the anti-pinch function.

[0052] like Figure 1 As shown, the pressure sensor assembly 20 also includes an encapsulation layer 23, which includes a first encapsulation portion 231 and a second encapsulation portion 232. The first encapsulation portion 231 covers the edge surface 13, and the second encapsulation portion 232 is connected to the first encapsulation portion 231. The second encapsulation portion 232 is used to connect with the groove 14. The first encapsulation portion 231 and the second encapsulation portion 232 form a receiving cavity for placing the resistance detection layer 21 and the connecting layer 22. On the cross-section of the encapsulation layer 23, the first encapsulation portion 231 and the second encapsulation portion 232 are arranged perpendicularly, so that the second encapsulation portion 232 fits into the groove 14, improving the structural stability and reliability of the pressure sensor assembly 20. At the same time, the encapsulation layer 23 protects the internal resistance detection layer 21 and the connecting layer 22, preventing the resistance detection layer 21 from being affected by environmental factors such as humidity changes, dust, and rain, which could damage the detection accuracy and further ensure the effectiveness of the anti-pinch function.

[0053] In this embodiment, the groove 14 is rectangular in shape on the cross-section of the glass assembly, and the second encapsulation part 232 is also rectangular. In other embodiments, the shape of the groove 14 and the shape of the second encapsulation part 232 are not limited to this, and can also be circular.

[0054] like Figure 1 As shown, the connecting layer 22 includes a cover portion 221 and an extension portion 222. The cover portion 221 is located within the first encapsulation portion 231, and the extension portion 222 is connected to the cover portion 221. The extension portion 222 is located within the second encapsulation portion 232. In the cross-section of the connecting layer 22, the cover portion 221 and the extension portion 222 are arranged perpendicularly. This arrangement allows the connecting layer 22 to be divided into the cover portion 221 and the extension portion 222 according to the structure of the groove 14. The extension portion 222 serves a fixing function, and the cover portion 221 is connected to the extension portion 222 to provide support for the resistance detection layer 21.

[0055] In this embodiment, the connecting layer 22 is a flexible substrate, which can be easily adjusted to different shapes to fit the structure of the groove.

[0056] In one embodiment, the resistance sensing layer 21 includes an electrode layer 211 and a piezoresistive sensing layer 212. The electrode layer 211 is located within the first encapsulation portion 231 and on the surface of the cover portion 221, and is connected to the wire 30. The piezoresistive sensing layer 212 is located within the first encapsulation portion 231 and on the surface of the electrode layer 211, and is electrically connected to the electrode layer 211.

[0057] The piezoresistive sensitive layer 212 is used to sense the pressure exerted by the obstacle on the glass body 10, which causes changes in the conductive path inside the piezoresistive sensitive layer 212, thereby generating a resistance change signal. Specifically, the greater the pressure, the worse the conductivity of the conductive path, and the resistance value of the entire sensitive layer will increase significantly.

[0058] The electrode layer 211 is electrically connected to the piezoresistive sensitive layer 212. The electrode layer 211 is used to transmit the resistance change signal (corresponding to the pressure value) to the input terminal of the control module through the wire 30. When the glass body 10 is running, the control module detects that the pressure value and duration have reached the preset value. The control module then drives the lifting motor to reverse, so that the glass body 10 drops a certain distance to achieve anti-pinch protection.

[0059] The connecting layer 22 is made of PET film, which has good flexibility and light transmittance.

[0060] The encapsulation layer 23 is made of transparent epoxy resin, which provides protection, light transmission and stable adhesion, making it suitable for complex environments such as automotive applications.

[0061] The electrode layer 211 is made of ITO thin film, which has high conductivity, high light transmittance and flexible adaptability.

[0062] The piezoresistive sensitive layer 212 is made of graphene composite material and has ultra-high sensitivity, which can accurately identify minute pressure and avoid missed detection by anti-pinch technology.

[0063] like Figure 1 As shown, the glass body 10 includes an inner glass layer 101 and an outer glass layer 102. A PVB layer 103 is provided between the inner glass layer 101 and the outer glass layer 102, and a groove 14 is provided at the edge of the PVB layer 103. The inner glass layer 101 and the outer glass layer 102 have the same thickness, and the thickness of the PVB layer 103 is less than the thickness of the inner glass layer 101 and the outer glass layer 102.

[0064] It should be noted that the edges of composite glass typically need to be assembled with the window frame and sealing strips. If grooves are cut into the glass layers, the flatness of the glass edges will be compromised, preventing the sealing strips from adhering tightly, leading to water and air leaks, or interference with the frame assembly. However, the PVB layer 103 is located between the two glass layers, and the grooves along its edges are not exposed on the outer surface of the glass. This ensures that the assembly and sealing between the glass and the external structure are not affected, and the appearance integrity of the glass is not compromised. Furthermore, the groove design along the edges of the PVB layer 103 utilizes the material properties of the PVB layer, specifically its flexibility, to absorb deformation differences, preventing gaps or damage at the groove edges due to thermal expansion and contraction, thus ensuring the installation stability of the wire 30 and the resistance detection layer 21. Additionally, the sealing properties of the PVB layer 103 isolate moisture and impurities, preventing short circuits and failure of the resistance detection layer 21 due to moisture, extending the sensor's lifespan.

[0065] The glass assembly integration process of this application includes the following steps: Step 1: Laser-cut an annular groove 14 at a preset position on the PVB layer 103, and process the roughness of the inner wall of the groove 14.
