[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply 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 a limitation on the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0043] Based on this, an embodiment of the present invention provides a sensing sheet, the identification line of which can be used as a cutting mark, so that the user can cut along the identification line to obtain sensing sheets of different sizes, thereby improving the convenience of use.

[0044] like Figure 1 As shown, an embodiment of the present application provides a cuttable sensing sheet, comprising a collecting portion 1, an interface portion 2 and at least one identification line 3; the collecting portion 1 is used to collect signals from a detection component; the interface portion 2 is electrically connected to the collecting portion 1 to transmit signals; at least one identification line 3 is arranged on the surface of the collecting portion 1 to define a cuttable area with the outer contour of the collecting portion 1.

[0045] In the present application, the collecting part 1 is made of a flexible, bendable and cuttable film material. It should be noted that the signal collected by the collecting part 1 can be any one of a pressure signal, a temperature signal, a humidity signal, etc., and the signal is not limited to the only one.

[0046] It is understandable that, since the collection part 1 is provided with the identification line 3, the user can cut the collection part 1 according to the identification line 3 to cut out the required sensing piece size, so that the outer contour of the collection part 1 is close to the contour of the part to be detected, which is more convenient for the installation and positioning of the collection part 1. At the same time, when it is necessary to detect the parts to be detected with different contour sizes, the user only needs to purchase a sensing piece of one specification, find the identification line 3 closest to the outer contour of the part to be detected on the collection part 1, and then cut the collection part 1 along the identification line 3, so that the size of the collection part 1 is roughly consistent with the size of the part to be detected, so that the sensing piece can be applied to the parts to be detected of different sizes, thereby improving the applicable scope of the sensing piece; in addition, in the production process, there is no need to independently set different production routes for the parts to be detected with different contours, which helps to reduce production costs and improve the production efficiency of the sensing piece.

[0047] See also Figure 2Furthermore, the collection part 1 includes at least two identification lines 3. Each identification line 3 corresponds to an outer contour of a different size, and each identification line 3 and the outer contour of the collection part 1 jointly define a cuttable area. In this arrangement, multiple identification lines 3 correspond to multiple sizes of collection parts 1 of different sizes, and multiple collection parts 1 of different sizes are available for users to choose from. The user can cut the collection part 1 according to the corresponding identification line 3 to cut out a collection part 1 of a size similar to that of the object to be detected, which helps to further improve the scope of application of the collection part 1. The present application does not specifically limit how to set the identification line 3 on the collection part 1, as long as the identification line 3 set on the collection part 1 can be easily identified by the user.

[0048] Optionally, the identification line 3 can be formed on the surface of the collection part 1 by electroplating, etching, silk screen printing, printing, etc.

[0049] The above-mentioned method for setting the marking line 3 can make the marking line 3 firmly attached to the collecting part 1, thereby preventing the marking line 3 from being worn due to external factors, making the marking line 3 unrecognizable.

[0050] As an implementation mode, each identification line 3 is arranged on the same side of the collecting portion 1 and is staggered, and each identification line 3 is set to the same color; and / or, each identification line 3 is arranged on the same side of the collecting portion 1 and is staggered, and each identification line 3 is set to the same line shape; that is, when there is no intersection between the identification lines 3 on the same surface of the collecting portion 1, each identification line 3 can be an identification line 3 of the same color and line shape, so that the user will not make cutting errors when cutting to the intersection, and setting each identification line 3 to the same color and line shape is more convenient for processing and manufacturing.

[0051] As another embodiment, the identification lines 3 are arranged on the same side of the collection part 1, and any two crossed identification lines 3 are arranged to have different colors and / or line shapes. That is, when there are crossed identification lines 3 on the same surface of the collection part 1, in order to facilitate the user's distinction, the two crossed identification lines 3 are identification lines 3 of different colors, or the two crossed identification lines 3 are identification lines 3 of different line shapes, or the two crossed identification lines 3 are identification lines 3 of different colors and different line shapes. Such a setting method can effectively distinguish the two crossed identification lines 3, and avoid the phenomenon that the user makes cutting errors when cutting.

[0052] The present application does not specifically limit the color and line shape of the identification line 3. The identification line 3 can be white, yellow, black, red or other colors that are easy for users to identify. The identification line 3 can also be a continuous straight line, dotted line, dotted line or other line shape.

[0053] Please continue reading Figure 1 and Figure 2Furthermore, the smallest identification line 3 among the identification lines 3 divides the acquisition part 1 into a signal transmission area 11 and a cutting area 12. The signal transmission area 11 is connected to the interface part 2 to transmit signals; the signal transmission area 11 is set in the area enclosed by the smallest identification line 3, and the smallest identification line 3 and the outer contour of the acquisition part 1 define the cutting area 12. The remaining identification lines 3 are all set in the cutting area 12.

[0054] In the present application, the sizes of the areas enclosed by different marking lines 3 on the collection part 1 are different. The smallest marking line 3 on the collection part 1 is the marking line with the smallest area enclosed on the collection part 1 .

[0055] It can be understood that the signal transmission area 11 is an area for transmitting signals and is an area that cannot be cut, while the cutting area 12 is an area that can be cut by the user. In the present application, the signal transmission area 11 is separated from the cutting area 12 by the smallest identification line 3 on the collection part 1, and the remaining identification lines 3 are set in the cutting area 12, which can prevent the user from cutting the signal transmission area 11 when cutting the collection part 1 according to the identification lines 3. This arrangement improves the reliability of the sensor sheet when it is used.

[0056] Please combine Figure 2 and Figure 3 Furthermore, the acquisition unit 1 further includes a plurality of sensing units 13 disposed in the signal transmission area 11 and the cutting area 12, and a signal transmission line 14 connecting the sensing unit 13 and the interface unit 2. The identification lines 3 are sequentially spaced in the cutting area 12, and the signal transmission line 14 extends from the signal transmission area 11 to the cutting area 12 to be connected to the sensing units 13.

[0057] It can be understood that the signal generated by the sensing unit 13 can be transmitted to the interface part 2 through the signal transmission line 14, and the interface part 2 can be connected to the external processing device to transmit the signal to the external device. In the present application, the sensing unit 13 can be any one of a temperature sensing unit, a pressure sensing unit, and a humidity sensing unit, which is not specifically limited here.

[0058] Specifically, the interface portion 2 is provided corresponding to the signal transmission area 11 and is provided with a signal transmission interface 21, and each sensing unit 13 is provided with a corresponding signal transmission line 14; one end of each signal transmission line 14 is connected to the sensing unit 13, and the other end passes through the signal transmission area 11 and is connected to the signal transmission interface 21. Of course, multiple sensing units 13 can also share a signal transmission line 14, and the signal transmission line 14 extends from the signal transmission area 11 to the cutting area 12 to connect each sensing unit 13 in sequence.

[0059] It is understandable that when the collection part 1 needs to be cut, the user selects the corresponding identification line 3 in the cutting area 12 according to the size of the object to be detected, and cuts the cutting area 12 along the identification line 3 to cut off the area outside the identification line 3, and retains the area within the identification line 3, so that the outer contour of the collection part 1 after cutting is roughly the same as the size of the object to be detected. Since the signal transmission area 11 is set within the smallest identification line 3, the signal transmission area 11 will not be cut when cutting along any identification line 3, that is, the signal transmission line 14 will not be cut when cutting along any identification line 3.

[0060] Furthermore, when cutting along the marking line 3, since the signal transmission line 14 connecting the interface part 2 and the sensing unit 13 extends from the signal transmission area 11 to the edge of the collection part 1 and is connected to the sensing unit 13, the signal transmission line 14 connecting the sensing unit 13 and the interface part 2 in the marking line 3 will not be cut. At the same time, since the marking lines 3 are sequentially spaced in the cutting area 12, when any marking line 3 is selected for cutting, the signal transmission line 14 connecting the sensing unit 13 and the interface part 2 in the area enclosed by the marking line 3 will not be cut. While ensuring that the complete sensing unit 13 is arranged in the collection part 1 after cutting, it avoids the situation that the sensing unit 13 in the local area of ​​the collection part 1 is disconnected from the interface part 2 after cutting and the signal cannot be collected, further improving the reliability of the sensing sheet.

[0061] The present application does not specifically limit whether the identification line 3 is closed. The identification line 3 can be an open curve or a straight line, or a closed curve or a straight line.

[0062] Please continue reading Figure 2 As an implementation mode, each identification line 3 is set as an open curve and has a starting end 31 and an ending end 32, the starting end 31 and the ending end 32 are located at the same edge of the collection part 1, and the interface part 2 is connected at the edge between the starting end 31 and the ending end 32; that is, when the collection part 1 and the interface part 2 are arranged in the same plane, the interface part 2 is connected to an edge of the collection part 1, and the identification line 3 is an open curve and has a starting end 31 and an ending end 32, and the starting end 31 and the ending end 32 of the identification line 3 are respectively connected to the above edge and are respectively arranged on both sides of the interface part 2. With such a setting mode, although the identification line 3 is an open curve, the size of the sensing area to be retained can be defined by the identification line 3 and the edge of the collection part 1. At the same time, since the starting end 31 and the ending end 32 of the identification line 3 are respectively arranged on both sides of the interface part 2, the interface part 2 will not be cut when cutting along the identification line 3, which further improves the reliability of the sensing sheet.

[0063] As another implementation, when the collection part 1 and the interface part 2 are arranged on different planes, the identification line 3 can be a closed curve or an open curve, and the interface part 2 is arranged close to the smallest identification line 3 on the collection part 1 .

[0064] The present application does not specifically limit the outer contour of the collection part 1 and the shape of the marking line 3. The outer contour of the collection part 1 can be circular, square, polygonal, elliptical, etc.; the marking line 3 can be circular, square, polygonal, elliptical, etc. The outer contour of the collection part 1 can be similar to the shape of the marking line 3, for example, both are circular; the outer contour of the collection part 1 can also be different from the shape of the marking line 3, for example, the outer contour of the collection part 1 is square, and the marking line 3 is a circular marking line. The collection part 1 can be provided with multiple marking lines 3 of the same type, or multiple marking lines 3 of different types.

[0065] See also Figures 2 to 4 As an implementation mode, each identification line 3 is provided on two opposite surfaces of the collection part 1 and is of the same type, and the identification lines 3 on the two opposite surfaces correspond to each other; each identification line 3 is provided on two opposite surfaces of the collection part 1 and is of the same type, and the identification lines 3 on the two opposite surfaces are staggered; that is, when a plurality of identification lines 3 of the same type are provided on the collection part 1, each identification line 3 is provided in sequence and has different sizes. Each identification line 3 includes a first identification line 33 with the smallest enclosed area and at least one second identification line 34 enclosed by the first identification line 33.

[0066] It can be understood that, since the area enclosed by the first identification line 33 is the smallest, the first identification line 33 is the smallest identification line 3 on the acquisition unit 1. The area defined by the first identification line 33 and the outer contour of the acquisition unit 1 is the cutting area 12, and the signal transmission area 11 is set in the area enclosed by the first identification line 33.

[0067] See also Figure 5 As an embodiment, each identification line 3 is provided on two opposite surfaces of the collection part 1, and the identification lines 3 on the two opposite surfaces are identification lines 3 of different types; that is, when a plurality of identification lines 3 of different types are provided on the collection part 1, the identification lines 3 of different types are sequentially spaced and distributed in the cutting area 12. For example, when a plurality of polygonal identification lines and arc-shaped identification lines are provided on the collection part 1, any polygonal identification line is provided between two arc-shaped identification lines. Furthermore, the arc-shaped identification line provided close to any polygonal identification line has substantially the same contour as the inscribed circle of the polygonal identification line. Such a setting makes the overall arrangement of the identification lines 3 more compact, and more identification lines 3 can be provided on the collection part 1 of the same size for the user to select when cutting, and at the same time, the cutting amount can be reduced during the cutting process.

[0068] In the present application, each identification line 3 can be set on the same surface of the collection part 1, and each identification line 3 can also be set on two opposite surfaces of the collection part 1. When the identification lines 3 are set on two opposite surfaces of the collection part 1, the identification lines 3 on the two opposite surfaces of the collection part 1 can be the same type of identification lines, or different types of identification lines. The signal transmission area 11 is set in the area enclosed by the smallest identification line 3 on the two opposite surfaces; the smallest identification line 3 on the two opposite surfaces and the outer contour of the collection part 1 define the cutting area 12, and the identification lines 3 on the two opposite surfaces are all set in the cutting area 12. In this way, the user can cut along the identification line 3 on one side of the collection part 1, or cut along the identification line 3 on the other side of the collection part 1. In this way, more identification lines 3 can be set on the collection part 1, which further improves the scope of application of the collection part 1 and helps to improve the convenience during use.

[0069] As an implementation mode, each identification line 3 is provided on two opposite surfaces of the collection part 1 and is of different types, and the identification lines 3 on the two opposite surfaces correspond one to one; that is, when the identification lines 3 on the two opposite surfaces of the collection part 1 are of the same type and the identification lines 3 on the two opposite surfaces correspond one to one. The identification lines 3 of the same size are provided at the same position on the two opposite surfaces, so that no matter which side of the collection part 1 faces the user, the user can quickly locate the identification line 3 to be cut, which is more convenient for the user to use; at the same time, when the identification line 3 on one side of the collection part 1 cannot be identified or is worn away due to external factors, the user can cut the collection part 1 according to the identification line 3 on the other side, which greatly improves the convenience during use.

[0070] See also Figure 6 , each identification line 3 is arranged on two opposite sides of the collection part 1 and is of the same type; the identification lines 3 on the two opposite sides are of different sizes and are staggered; that is, the identification lines 3 on the two opposite sides of the collection part 1 are of the same type, and the sizes of the identification lines 3 on the two opposite sides are different. It can be understood that when it is necessary to set the same type of identification lines with relatively small size changes on the collection part 1, if all the identification lines 3 are arranged on the same side, the spacing between adjacent identification lines 3 will be small, and such a setting method is not convenient for users to identify. However, setting any one of the two identification lines 3 with smaller changes on the other side of the collection part 1 can increase the spacing between two adjacent identification lines 3 on the same side, which is more conducive to user identification.

[0071] See also Figure 7 As an implementation mode, the marking lines 3 on the two opposite sides of the collection part 1 are of different types, so that the user can select the marking lines 3 similar to the type of the part to be detected according to actual needs, further enriching the cuttable types of the collection part 1 and having high practicality.

[0072] See also Figure 8As an implementation method, any marking line 3 on the collection part 1 is also provided with an area mark 15 corresponding thereto, and the area mark 15 is used to feedback the area size of the collection part 1 retained after cutting according to the corresponding marking line 3. In this way, the user can intuitively obtain the size of the area enclosed by each marking line 3 through the area mark 15, and can then more conveniently and accurately select which marking line 3 needs to be cut.

[0073] See also Fig. 9 The second embodiment of the present application provides a sensing sheet, the principle of which is basically the same as that of the above-mentioned sensing sheet, with the only difference being that in this embodiment, the identification line 3 on the collection portion 1 includes a scale line 35 arranged along the edge of the collection portion 1, and a numerical value is marked on the scale line 35, and the numerical value on the scale line 35 is set to increase from one end of the scale line 35 to the other end; or, the numerical value on the scale line 35 is set to increase from the midpoint of the scale line 35 to both ends.

[0074] It can be understood that when the collection part 1 needs to be cut, the corresponding scale can be selected through the scale line 35 to cut the collection part 1 so that the outer contour of the collection part 1 is roughly consistent with the outer contour of the part to be detected. In this way, the collection part 1 that is relatively consistent with the outer contour of the part to be detected can be cut, which increases the application range of the collection part 1; in addition, the outer contour of the part to be detected can be measured through the scale line 35, which helps to reduce the error between the size of the part to be detected and the size of the collection part 1.

[0075] It should be noted that, in this embodiment, the outer contour of the collecting portion 1 is set to be a square as an example for explanation; of course, in other embodiments, the outer contour of the collecting portion 1 can also be set to other shapes.

[0076] Optionally, the scale lines 35 are arranged in two groups, and the two groups of scale lines 35 are arranged on two adjacent sides of the collection part 1. In this arrangement, the length of the collection part 1 to be retained can be selected through one group of scale lines 35 to cut one side of the collection part 1, and the width of the collection part 1 to be retained can be selected through the other group of scale lines 35 to cut the other side of the collection part 1, so that the outer contour of the collection part 1 is roughly consistent with the outer contour of the part to be detected.

[0077] See also Fig.10 The third embodiment of the present application provides a cuttable thin film pressure sensing sheet. The structure, cutting principle and beneficial effects of the thin film pressure sensing sheet are basically the same as those of the above-mentioned sensing sheet, and will not be described in detail here. The difference is that in the thin film pressure sensing sheet, the sensing unit 13 is set as a unit that can generate an electrical signal change after being pressurized.

[0078] See also Figures 10 to 13Specifically, the collection part 1 is composed of a stacked sensing material layer 17 and an electrode layer 16. The signal transmission line 14 is arranged on the electrode layer 16 and includes a plurality of first electrode lines 161 and a second electrode line 162. Each first electrode line 161 intersects with a plurality of second electrode lines 162 to form a detection point 163. Each detection point 163 forms a sensing unit 13 with the corresponding sensing material layer 17. When the collection part 1 is pressed, the contact area between the sensing material layer 17 and the detection point 163 will change, thereby generating a change in the electrical parameter. The first electrode line 161 and the second electrode line 162 are both electrically connected to the interface part 2. When the surface of the sensing material layer 17 is pressed, each first electrode line 161 receives the excitation signal in turn, and each second electrode line 162 simultaneously obtains the electrical parameter information of each sensing unit 13 on the same first electrode line 161 and transmits it to the interface part 2.

[0079] In this embodiment, the arrangement of the first electrode lines 161 and the second electrode lines 162 on the collection part 1 is the same as the arrangement of the signal transmission line 14 on the collection part 1 in the above embodiment. As an implementation mode, each first electrode line 161 is composed of a first conductive line 1611 and a first sensing line 1612 that are connected; each second electrode line 162 is composed of a second conductive line 1621 and a second sensing line 1622 that are connected, and any first sensing line 1612 intersects with different second sensing lines 1622 to form detection points 163 at different positions of the first sensing line 1612. Since a plurality of first electrode lines 161 and second electrode lines 162 are distributed on the collection part 1, a plurality of sensing units 13 can be formed on the collection part 1.

[0080] In this embodiment, each first sensing line 1612 is distributed in sequence at intervals in the cutting area 12 and the signal transmission area 11, and each first conductive wire 1611 extends from the signal transmission area 11 to the cutting area 12 to be connected to each corresponding first sensing line 1612; each second sensing line 1622 is distributed in sequence at intervals in the cutting area 12 and the signal transmission area 11, and each second conductive wire 1621 extends from the signal transmission area 11 to the cutting area 12 to be connected to each corresponding second sensing line 1622.

[0081] It is understandable that when the collection part 1 needs to be cut, the user selects the corresponding identification line 3 in the cutting area 12 according to the size of the object to be detected, and cuts the cutting area 12 along the identification line 3 to cut off the area outside the identification line 3, and retains the area within the identification line 3, so that the outer contour of the collection part 1 after cutting is roughly the same as the size of the object to be detected. Since the signal transmission area 11 is set within the smallest identification line 3, the signal transmission area 11 will not be cut when cutting along any identification line 3, that is, the signal transmission line 14 will not be cut when cutting along any identification line 3.

[0082] Furthermore, when cutting along the identification line 3, since the first wire 1611 and the second wire 1621 extend from the signal transmission area 11 to the cutting area 12, after the cutting is completed, the first wire 1611 and the second wire 1621 connecting the sensing unit 13 on the collection part 1 and the interface part 2 will not be cut. While ensuring that a complete sensing unit 13 is arranged in the collection part 1 after the cutting, it avoids the situation where the sensing unit 13 in a local area of ​​the collection part 1 is disconnected from the interface part 2 after the cutting, thereby preventing the signal from being collected. This further improves the reliability of the thin film pressure sensing sheet.

[0083] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
