Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a segmented capacitive sensing sensor, a rubber strip, and a vehicle. Background Technology

[0002] Traditional capacitance sensing devices typically use sensors with separate PCB capacitor boards, wires, or metal sheets to collect changes in capacitance. However, in some specialized applications, these sensors often fail to meet the product's design performance requirements.

[0003] For example, in the application scenario of vehicle electric magnetic attraction system, its working principle is to use the human body charge accumulation effect to detect whether a hand is approaching the magnetic attraction edge such as the door panel by sensing the charge change of the capacitance sensor, and then control the start and stop of the electric magnetic attraction system.

[0004] Currently, this use case has the following problems: During the door closing process, when a traditional sensor approaches the metal body of the car, it increases the sensor's charge, causing the algorithm to detect the presence of a living being and resulting in a failed door closing. Similarly, rainwater can cause changes in charge, leading to false triggering and door closing failure. The common characteristic of both scenarios is the unexpected charge changes observed in the sensor.

[0005] Furthermore, with traditional sensors that use solid metal sheets or FPCs (flexible printed circuit boards), when multiple sensors coexist, if one sensor is pressed, another sensor will experience an increase in charge due to the charge conduction effect, which may lead to misjudgment and failure to engage.

[0006] Therefore, it is necessary to invent a sensor that can avoid or reduce accidental touches. Utility Model Content

[0007] In order to overcome the technical problem that traditional sensors in the vehicle electric system engagement system described above are prone to false triggering, leading to failure of electric system engagement, this utility model provides a segmented capacitive sensing sensor, a rubber strip, and a vehicle.

[0008] The technical solution adopted by this utility model to solve its problem is: The segmented capacitive sensing sensor includes at least two sensing segments, each including a first sensing segment and a second sensing segment. Either the first sensing segment or the second sensing segment is provided with a first insulating layer, which is used to prevent the first signal generated by the first sensing segment and the second signal generated by the second sensing segment from interfering with each other.

[0009] As a preferred embodiment, the first sensing segment and the second sensing segment are arranged sequentially along the length direction of the segmented capacitive sensing sensor. The first sensing segment includes a wire and a first insulating layer arranged sequentially from the inside to the outside. The second sensing segment includes a wire, the first insulating layer, a first conductive layer, and a second insulating layer arranged sequentially from the inside to the outside.

[0010] As a preferred embodiment, the sensing segment further includes a third sensing segment. The first sensing segment, the second sensing segment, and the third sensing segment are arranged sequentially along the length direction of the segmented capacitive sensing sensor. The third sensing segment includes a wire, a first insulating layer, a first conductive layer, a second insulating layer, a second conductive layer, and a third insulating layer arranged sequentially from the inside to the outside.

[0011] As a preferred embodiment, the segmented capacitive sensor is a wire-type capacitive sensor, and the sensing segment is a wire segment.

[0012] As a preferred embodiment, the first conductive layer and the second conductive layer are mesh conductors, and the fill rate of the mesh conductor is 10-40%.

[0013] As a preferred embodiment, the first insulating layer and the second insulating layer have the same dielectric constant; or, the first insulating layer and the second insulating layer have different dielectric constants; wherein, the dielectric constants of the first insulating layer and the second insulating layer are both greater than or equal to 2.5.

[0014] Based on the same design concept, this utility model also provides an adhesive strip, in which the segmented capacitive sensing sensor described above is applied, and the adhesive strip and the segmented capacitive sensing sensor are integrated into one piece.

[0015] As a preferred embodiment, the adhesive strip includes an adhesive strip body, an adhesive strip lip extending outward from the outer side of the adhesive strip body, a receiving cavity formed between the adhesive strip lip and the adhesive strip body, and the segmented capacitive sensing sensor is installed in the receiving cavity.

[0016] As a preferred embodiment, the inner side of the adhesive strip body is provided with a plurality of adhesive strip fixing bands extending inward, and the outer side of the adhesive strip body is provided with an adhesive strip buffer portion extending outward, the interior of the adhesive strip buffer portion forming a buffer zone.

[0017] Based on the same design concept, this utility model also provides a vehicle including the above-mentioned rubber strip, the vehicle including a door structure, and the rubber strip being fixedly installed on the door structure.

[0018] In summary, compared with the prior art, the segmented capacitive sensing sensor, adhesive strip, and vehicle provided by this utility model have at least the following technical advantages: 1) The segmented capacitive sensing sensor of this invention uses a multi-layer conductor + insulating outer coating as a carrier. Depending on the specific application scenario and requirements, the sensor can be divided into at least two sensing segments. This multi-segment capacitive design determines the presence of living organisms by comparing the capacitance changes of each sensing segment with the calibration value, thus avoiding false triggering due to external factors such as rain. Furthermore, by setting a conductive layer in the form of a mesh conductor, the sensor's sensitivity can be improved, and crosstalk between sensing segments can be avoided, thereby further reducing the occurrence of false triggering.

[0019] 2) The adhesive strip and segmented capacitive sensor are integrated into a single unit, allowing the segmented capacitive sensor to be embedded within the adhesive strip. This results in a more aesthetically pleasing installation and solves the problems associated with traditional copper sheet sensors or PCB designs, such as difficulty in installation and fixation, and inability to meet waterproofing requirements. Furthermore, the segmented capacitive sensor can deform freely after installation, easily conforming to irregularly shaped door edges, eliminating the need to consider issues such as riveting connections between the wiring harness and the sensor, thereby reducing costs such as mold opening fees.

[0021] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] In the technical solution of this utility model, a segmented capacitive sensing sensor is provided. The segmented capacitive sensing sensor includes at least two sensing segments, including a first sensing segment and a second sensing segment. Either the first sensing segment or the second sensing segment is provided with a first insulating layer 12 (preferably, the first insulating layer 12 is provided on the outside of the first sensing segment). The first insulating layer is used to shield or isolate the first signal generated by the first sensing segment and the second signal generated by the second sensing segment so that they do not interfere with each other.

[0025] The following provides a specific embodiment of this segmented capacitive sensing sensor.

[0026] Example 1 In the first embodiment of this utility model, a structural design scheme for a segmented capacitive sensing sensor 1 is provided.

[0027] See Figure 1 As shown in the technical solution of this embodiment, the segmented capacitive sensing sensor 1 of this utility model is composed of multiple sensing segments. Specifically, the segmented capacitive sensing sensor 1 can be divided into at least two sensing segments along its length. The number of sensing segments can be two, three, four, or more, and the specific number is determined according to actual needs and design requirements. In this embodiment, no specific upper limit is set on the number of sensing segments.

[0028] See Figure 1 As shown, the sensing segment includes at least a first sensing segment (i.e., Figure 1 The L1 segment shown) and the second sensing segment (i.e. Figure 1As shown in segment L2), the first sensing segment and the second sensing segment are arranged sequentially along the length of the segmented capacitive sensing sensor. The first sensing segment includes at least a wire 11 and a first insulating layer 12 arranged sequentially from the inside to the outside. The second sensing segment includes at least a wire 11, a first insulating layer 12, a first conductive layer 13, and a second insulating layer 14 arranged sequentially from the inside to the outside. Specifically, for the first sensing segment, the wire 11 serves as the core component for signal detection and acts as the core for transmitting electrical signals. The first insulating layer 12 is an insulating layer used to wrap the wire 11 and isolate it from the external conductive environment. For the second sensing segment, the wire 11 and the first insulating layer 12 are shared inner layer structures with the first sensing segment. The first conductive layer 13 serves as the core component for signal detection in the second sensing segment. The first insulating layer 12 also isolates crosstalk between adjacent sensing segments (i.e., the first and second sensing segments) to ensure that the capacitance change signals of each segment are independent and accurate. The outermost second insulating layer 14 protects the internal structure and has functions such as insulation or wear resistance, or acts as a shielding insulation when a third sensing segment is present.

[0029] Based on the above structural design, the working principle of the segmented capacitive sensing sensor 1 is briefly described below: When the wire 11 is energized, it generates a magnetic field. When a human body approaches the first sensing segment, it affects the capacitance of the first sensing segment, thereby generating a first signal, which is transmitted to the chip. When the first conductive layer 13 is energized, it generates a magnetic field. When a human body approaches the second sensing segment, the first conductive layer 13 generates a second signal, which is transmitted to the chip. Because of the presence of the first insulating layer 12, when a human body approaches the second sensing segment, only the first conductive layer 13 generates the second signal, and the first sensing segment does not generate the first signal incorrectly or interfere with the first signal of the first sensing segment (for example, causing it to have a certain increment, leading to misjudgment, etc.).

[0030] In practical use, the capacitance changes of different sensing segments are collected and compared with preset calibration values ​​to distinguish between "the presence of living organisms" and "external interference such as rainwater and dust." Based on the above multi-segment capacitance design, the presence of living organisms can be determined by comparing the capacitance changes of each sensing segment with the calibration values, thus avoiding false triggering caused by external factors such as rainwater. Furthermore, by setting each insulating layer (with a low dielectric constant), the sensor's sensitivity can be improved, and crosstalk between sensing segments can be avoided, thereby further reducing the occurrence of sensor false triggering.

[0031] See Figure 1 As shown, in a preferred embodiment, the sensing segment further includes at least a third sensing segment (i.e., Figure 1As shown in segment L3), the first sensing segment, the second sensing segment, and the third sensing segment are arranged sequentially along the length of the segmented capacitive sensing sensor. The third sensing segment includes at least, from the inside out, a wire 11, a first insulating layer 12, a first conductive layer 13, a second insulating layer 14, a second conductive layer 15, and a third insulating layer 16. Specifically, for the third sensing segment, the wire 11, the first insulating layer 12, the first conductive layer 13, and the second insulating layer 14 are shared inner layer structures with the first or second sensing segment; the second conductive layer 15 serves as the core component for signal detection in the third sensing segment; the second insulating layer 14 isolates crosstalk between adjacent sensing segments (i.e., the second and third sensing segments) to ensure that the capacitance change signals of each segment are independent and accurate; the outermost third insulating layer 16 is an insulating layer used to protect the internal structure, and also has insulating or wear-resistant functions, or serves as a shielding insulation when a fourth sensing segment is present.

[0032] Similarly, when the number of sensing segments is N (N is greater than 3), the sensing segments also include at least the fourth sensing segment, ..., the (N-1)th sensing segment, and the Nth sensing segment. The Nth sensing segment is provided with an internal structure shared with the first sensing segment, ... or the (N-1)th sensing segment, as well as the (N-1)th conductive layer and the Nth insulating layer from the inside out. At this time, the Nth insulating layer serves as the outermost covering structure of the sensor.

[0033] Based on the structural design of this embodiment, the following example illustrates one method for implementing capacitance detection (the actual method is not limited to this): 1. Collect the capacitance changes of different sensing segments. For example, when there are 2 sensing segments, collect the capacitance changes of the first and second sensing segments; when there are 3 sensing segments, collect the capacitance changes of the first, second, and third sensing segments.

[0034] 2. If two or fewer sensing segments reach the evaluation threshold, and the sum of the capacitance changes of all sensing segments is less than the calibrated value, then a living organism is determined to be present. The principle is as follows: When a living organism (such as a human body) approaches, it usually only affects a few local sensing segments (for example, if a human hand approaches a certain part of the sensor, only the capacitance changes of two adjacent sensing segments may reach the threshold), and because the size of the living organism is limited, the total impact on the overall capacitance is small and will not exceed the calibrated value.

[0035] 3. If two or more sensing segments reach the evaluation threshold, and the sum of the capacitance changes of all sensing segments exceeds the calibrated value, it is determined to be a false trigger, and there is actually no living organism present. The principle is as follows: interference such as rain and fog has the characteristic of covering a large area (for example, rain wetting the entire sensor will cause multiple adjacent sensing segments to be affected simultaneously). Therefore, the number of triggers is large, and because of the wide coverage, the total capacitance change will significantly exceed the impact of living organisms, exceeding the calibrated value.

[0036] Ultimately, by using the dual conditions of "number of triggers in the sensing segment" and "total capacitance change", the system can distinguish between "biological proximity" and "external interference such as rainwater", thereby reducing the occurrence of sensor false triggering.

[0037] It is worth mentioning that the evaluation threshold mentioned in the above scheme is a preset threshold that the capacitance change of a single sensing segment needs to reach, and the calibration value is a critical value of the sum of the capacitance of biological and interference determined by a large number of experiments.

[0038] In a preferred embodiment, see Figure 1 As shown, the segmented capacitive sensor is preferably configured as a wire-type capacitive sensor, and each sensing segment is a wire segment structure design.

[0039] The wire-type capacitive sensor can be designed as an integrated structure or as a split structure, that is, each sensing segment is designed separately or each layer is designed separately.

[0040] In an optional embodiment, the first conductive layer 13 and the second conductive layer 15 are mesh conductor structures, designed to further reduce signal crosstalk between adjacent sensing segments. The mesh conductor design creates a Faraday cage effect through the conductive network, effectively blocking most interference signals and reducing sensor false triggering. Furthermore, the mesh structure design has a certain degree of tensile and abrasion resistance, capable of withstanding slight pulling and friction during installation or use of the wire-type sensor, protecting the internal insulation layer and wire 11.

[0041] Furthermore, the fill rate of the aforementioned mesh conductor is preferably 10-40%.

[0042] In one optional embodiment, the first insulating layer 12 and the second insulating layer 14 have the same dielectric constant. This simplifies the capacitance calculation model and makes the capacitance variation of the sensing segment more stable (e.g., the external environment has a consistent effect on both sensing layers, facilitating threshold calibration). Alternatively, the first insulating layer 12 and the second insulating layer 14 may have different dielectric constants. This allows for the design of more complex capacitance response curves using the different dielectric properties of the two sensing layers (e.g., the first insulating layer 12 uses a high dielectric constant material to enhance sensitivity to nearby objects, while the second insulating layer 14 uses a low dielectric constant material to reduce interference at long distances), thereby adapting to more refined detection requirements.

[0043] Preferably, the dielectric constant of both the first insulating layer 12 and the second insulating layer 14 is greater than or equal to 2.5. This value is much higher than the dielectric constant of air and the dielectric constant of some common insulating materials. It also has good insulation and weather resistance, can adapt to outdoor humid environments, and meets the structural protection requirements of wire-type sensors.

[0044] Based on the structural design of this scheme, the capacitance C generated by the sensor satisfies the following formula: C = ε0·εr·A / d.

[0045] Where A is the area of ​​the two plates facing each other (in this scheme, the area of ​​the hand and the inner conductor facing each other or overlapping); ε0 is the vacuum permittivity; εr is the relative permittivity (in this scheme, the inner insulating layer); and d is the plate spacing (in this scheme, the thickness of the outermost insulating layer).

[0046] In one optional embodiment, the first and second sensing segments have the same length. This design provides strong structural symmetry, facilitating overall sensor layout and simplifying the manufacturing process. Furthermore, the base capacitance values ​​of each sensing segment are more comparable, making it easier to uniformly calibrate the "evaluation threshold" and "total calibration value." Alternatively, the first and second sensing segments may have different lengths. This design allows for a natural differentiation of capacitance values ​​through length differences (different lengths result in different base capacitances), aiding in the differentiation of signals from different sensing segments and reducing the risk of crosstalk and misjudgment.

[0047] Preferably, the lengths of both the first and second sensing segments are greater than or equal to 5 cm. Living organisms (such as human limbs) typically have a certain size or range of motion. A sensing segment length of 5 cm or more ensures that when an organism approaches, it effectively covers (or at least partially covers) the sensing segment, thereby triggering a identifiable change in capacitance. If the sensing segment is too short, it may result in missed detections where an organism approaches but does not cover the sensing segment.

[0048] Example 2 In the second embodiment of this utility model, a specific structural design scheme is provided regarding how the segmented capacitive sensing sensor 1 is applied to the adhesive strip 2.

[0049] See Figure 2 As shown, in the technical solution of this embodiment, based on the wire structure design of the segmented capacitive sensing sensor 1, the adhesive strip 2 and the segmented capacitive sensing sensor 1 can be designed as an integrated unit. The segmented capacitive sensor can be an integrated structure or a separate structure, i.e., each sensing segment is a separate design or each layer of the structure is a separate design.

[0050] Optionally, in practical applications, the segmented capacitive sensing sensor 1 can be flexibly embedded into the adhesive strip 2 using processes such as die casting. This process allows the segmented capacitive sensing sensor 1 and the adhesive strip 2 to be tightly integrated, forming a stable, one-piece structure. This fundamentally solves the problem of traditional sensors being difficult to fix precisely during installation, and prone to loosening or displacement, greatly improving the convenience and stability of sensor installation.

[0051] Furthermore, thanks to the design where the segmented capacitive sensing sensor 1 is fully embedded within the adhesive strip 2, its sealing performance is significantly enhanced. This solves the technical problem that traditional copper sheet or PCB-designed sensors cannot meet stringent waterproof requirements due to their structural characteristics, effectively coping with complex external environments such as humidity and rain. At the same time, this integrated design eliminates the need for additional installation components, avoiding the problem of exposed parts affecting the overall appearance and significantly improving the overall aesthetics of the adhesive strip 2.

[0052] After installation, based on the wire structure design, the segmented capacitive sensing sensor 1 can undergo free deformation, easily fitting irregular curved surfaces such as door edges. This eliminates the need for complex molds to adapt to special shapes, thus significantly reducing production costs such as mold opening fees. While ensuring the performance, it also achieves effective cost control.

[0053] See Figure 2 As shown, in a preferred embodiment, the adhesive strip 2 includes an adhesive strip body 21, an adhesive strip lip 22 extending outward from the outer side of the adhesive strip body 21, and a receiving cavity formed between the adhesive strip lip 22 and the adhesive strip body 21. The segmented capacitive sensing sensor 1 is installed in the receiving cavity.

[0054] In this preferred embodiment, the lip 22 extending from the outer side of the adhesive strip body 21, together with the adhesive strip body 21, forms a receiving cavity, providing installation space for the segmented capacitive sensing sensor 1. The lip 22 itself possesses a certain degree of sealing, effectively preventing external dust, moisture, oil, and other impurities from entering the receiving cavity. This avoids performance degradation or malfunction of the segmented capacitive sensing sensor 1 due to contaminant corrosion, significantly improving the sensor's anti-interference capability and lifespan. Furthermore, when the adhesive strip 2 is subjected to external forces such as compression or vibration, the receiving cavity formed by the lip 22 and the adhesive strip body 21 can absorb the impact force through its own elastic deformation, preventing the sensor from shaking or shifting within the cavity. This ensures the sensor remains in the preset working position, guaranteeing the stability and accuracy of the sensing signal and reducing detection errors caused by unstable installation. In addition, the presence of the receiving cavity provides a certain buffer space for the segmented capacitive sensing sensor 1. When the rubber strip 2 is compressed and deformed, the cavity can adjust its shape to provide a buffer for the sensor, preventing the sensor from being damaged due to excessive force, ensuring its structural integrity and performance stability during long-term use, and indirectly reducing the product's maintenance costs.

[0055] See Figure 2 As shown, in another preferred embodiment, a plurality of adhesive strip fixing bands 23 are provided on the inner side of the adhesive strip body 21, and an adhesive strip buffer portion 24 is provided on the outer side of the adhesive strip body 21, with a buffer zone 25 formed inside the adhesive strip buffer portion 24.

[0056] In this preferred embodiment, the rubber strip fixing buckle 23 on the inner side of the rubber strip body 21 can form multi-point engagement with the structure of the installation part (such as the edge of the door). By increasing the contact friction and mechanical locking effect, it effectively prevents the rubber strip 2 from slipping or falling off during long-term use. Even under dynamic working conditions such as vibration and impact, the fixing buckle can firmly grasp the installation surface, ensuring that the rubber strip 2 always maintains the preset installation position and shape, providing a reliable guarantee for the stability of the overall structure.

[0057] Meanwhile, the rubber strip buffer portion 24 extending from the outer side of the rubber strip body 21 and the buffer zone 25 formed inside it have buffering and adaptation functions. Specifically, the rubber strip buffer portion 24 can absorb external impact forces through its own elastic deformation. When the rubber strip 2 is subjected to external forces such as compression or collision, the buffer portion can gradually release energy through compression deformation, preventing the external force from being directly transmitted to the rubber strip body 21 and the segmented capacitive sensing sensor 1 inside, thus providing good shock absorption protection. Furthermore, the presence of the buffer zone 25 allows the rubber strip 2 to better adapt to dimensional errors and irregular structures in the installation environment. By compensating for gaps through its own deformation, it ensures a tight fit between the rubber strip 2 and the mating parts, enhancing sealing performance and preventing wear and abnormal noise caused by hard contact.

[0058] Example 3 In the third embodiment of this utility model, a structural design scheme is provided regarding how the segmented capacitive sensing sensor 1 and the adhesive strip 2 are applied to a vehicle.

[0059] See Figure 1 As shown, in the technical solution of this embodiment, the vehicle includes a door structure, and the adhesive strip 2 of the above embodiment is fixedly installed on the door structure.

[0060] Specifically, the rubber strip 2 can be installed on the edge of the door structure using a multi-point interlocking method via the rubber strip fixing buckle 23. Vehicles generate continuous vibrations during operation, and the opening and closing of the door also brings impact forces. The rubber strip fixing buckle 23, by enhancing contact friction and mechanical locking, firmly fixes the rubber strip 2 to the door, effectively preventing it from slipping or falling off due to vibration and impact, thus providing reliable support for the stable operation of the door structure.

[0061] It is worth mentioning that the means of transportation in this utility model include, but are not limited to, land vehicles, water vehicles, and air vehicles.

[0062] More specifically, land transportation includes, but is not limited to, cars, SUVs, sports cars, buses, subways, light rail, and trains; water transportation includes, but is not limited to, passenger ships, cruise ships, ferries, and speedboats; and air transportation includes, but is not limited to, cable cars running on rails.

[0063] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
