Detailed Implementation

[0039] The present invention will be further described below with reference to the specific accompanying drawings and embodiments.

[0040] To enable sliding sensing on flexible carriers, this invention provides a sliding sensing device suitable for flexible carriers. Specifically, the sliding sensing device includes:

[0041] Sliding base 1;

[0042] A touch sensing unit, fabricated on a sliding substrate 1, includes a plurality of touch sensors arranged sequentially, wherein...

[0043] The touch sensor includes a base electrode unit printed on a sliding substrate 1 and a touch electrode unit 7 located above the base electrode unit, wherein the touch electrode unit 7 can approach and contact the base electrode unit after being touched and pressed.

[0044] The base electrode unit includes a base first electrode 6 and a base second electrode 5 that is separate from the base first electrode 6. When the touch electrode unit 7 contacts the base electrode unit, the base first electrode 6 is electrically connected to the base second electrode 5 through the touch electrode unit 7.

[0045] The first electrode 6 of the substrate of all touch sensors is adapted to and connected to the sensing resistor area 4 printed on the sliding substrate 1, and is connected to the first sliding sensing electrode 2 through the sensing resistor area 4.

[0046] The second electrode 5 of the substrate of all touch sensors is connected to the second sliding sensing electrode 3 printed on the sliding substrate 1.

[0047] Figures 1-4 The figure shows an embodiment of a sliding sensing device. As can be seen from the figure, the sliding sensing device includes at least a sliding substrate 1. The sliding substrate 1 includes a TPU (thermoplastic polyurethane elastomer) film or a PI film. That is, the sliding substrate 1 can be made of TPU film or PI film. The sliding sensing device can be assembled on a flexible carrier using the sliding substrate 1.

[0048] To achieve the purpose of sliding sensing, a touch sensing unit should be provided on the sliding base 1. The touch sensing unit should include multiple touch sensors arranged in sequence. Figure 1 and Figure 4 In this system, multiple touch sensors are arranged in a straight line, and the touch sensors can be used to realize the function of a touch switch. Generally, the touch sensors can adopt the same structural form, and different touch sensors are independent of each other. When touching a touch sensor in a different position, the current touch position state can be determined.

[0049] In a specific implementation, the touch sensor may include a base electrode unit and a touch electrode unit 7. The base electrode unit is screen-printed on the sliding substrate 1, and the touch electrode unit 7 is above the base electrode unit. When the touch sensor is touched, the touch electrode unit 7 is pressed. After the touch electrode unit 7 is pressed, the touch electrode unit 7 can move closer to the base electrode unit and make contact with the base electrode unit.

[0050] Figures 1-5 The image shows an embodiment of a base electrode unit, which may include a base first electrode 6 and a base second electrode 5. The base first electrode 6 and the base second electrode 5 are separated from each other. When the touch electrode unit 7 contacts the base electrode unit, specifically when the touch electrode unit 7 contacts the base first electrode 6 and the base second electrode 5, the base first electrode 6 can then be electrically connected to the base second electrode 5 through the touch electrode unit 7. It can be understood that after the base first electrode 6 and the base second electrode 5 are electrically connected, a touch sensing circuit can be formed.

[0051] To enable sensing of different sliding touches, the first electrode 6 of the substrate of all touch sensors should be adapted and connected to the sensing resistor area 4 printed on the sliding substrate 1. Then, it is connected to the first sliding sensing electrode 2 via the sensing resistor area 4. Simultaneously, the second electrode 5 of the substrate of all touch sensors is connected to the second sliding sensing electrode 3 printed on the sliding substrate 1. It should be noted that the first sliding sensing electrode 2 and the second sliding sensing electrode 3 can be connected to an external controller or control device so that the external controller can determine the current touch position state.

[0052] In one embodiment of this utility model, the sensing resistor region 4 includes a carbon wire body, and a carbon wire resistor is formed based on the carbon wire body of the sensing resistor region 4, wherein...

[0053] The carbon wires are arranged in an array on the sliding substrate 1.

[0054] When the sensing resistor region 4 is made of carbon wire, it can be formed on the sliding substrate 1 by screen printing conductive carbon paste, thus creating a carbon wire resistor. The carbon wires are arranged in an array on the sliding substrate 1. Figures 1-4 The illustration shows an embodiment in which carbon wires are arranged in an array on a sliding substrate 1. The first electrode 6 of the substrate of all touch sensors is electrically connected to the carbon wires. Based on the connection position between the touch sensor and the carbon wire, the touch resistance corresponding to different touch sensors after touch can be determined.

[0055] Figure 1 and Figure 4 In the diagram, if the resistance corresponding to the leftmost touch sensor is R, then when sliding from left to right, the resulting touch resistances can be 2R, 3R, 4R, and 5R respectively. Therefore, by recording the changes in resistance values, the direction of finger movement can be determined, thereby enabling the detection of the sliding position. When the touch sensing unit includes other numbers of touch sensors, please refer to the explanation here; examples will not be provided here.

[0056] Depend on Figures 1-4It is known that when the carbon wires are arranged in an array, the sensing resistance area 4 has tensile strength, and the resistance change due to stress deformation is small. The sensing resistance area 4 is located outside the area affected by finger pressing and will not interfere with the detection of touch pressing at adjacent points. In addition, the sliding touch device of this utility model can be connected to an external controller only through the first sliding sensing electrode 2 and the second sliding sensing electrode 3, effectively saving cost and space.

[0057] In one embodiment of this utility model, the touch electrode unit includes a touch substrate 10 and a touch electrode plate 13 disposed on the touch substrate 10, wherein...

[0058] The touch electrode 13 is located above the base electrode unit, and a plate movement cavity 9 is provided between the touch base 10 and the sliding base 1 to allow the touch electrode 13 to reciprocate.

[0059] The touch plate 13 moves within the plate movement cavity 9 and can contact the first electrode 6 and the second electrode 5 of the substrate, so that the first electrode 6 of the substrate is electrically connected to the second electrode 5 of the substrate through the touch plate 13.

[0060] Figure 5 The figure shows one embodiment of a touch electrode unit. As can be seen from the figure, the touch electrode unit may include at least a touch substrate 10 and a touch electrode plate 13. The touch electrode plate 13 should be made of a conductive material, such as a conductive carbon plate. In addition, the first electrode 6 and the second electrode 5 of the substrate are both silver electrodes. Of course, the touch electrode plate 13, the first electrode 6, and the second electrode 5 of the substrate can also be made of other materials. The conductive material used can be determined according to needs, such as being able to meet the requirements of sliding sensing when assembled on a flexible carrier.

[0061] Understandably, when the touch electrode unit is pressed, the touch electrode plate 13 should be able to contact the first electrode 6 and the second electrode 5 of the base. After the touch electrode unit is pressed, the touch electrode plate 13 should be reset to prepare for subsequent presses, that is, the touch electrode plate 13 should have the ability to reciprocate. In order to realize the reciprocating motion of the touch electrode plate 13, a plate movement cavity 9 should be included, in which the touch electrode plate 13 can reciprocate. The touch movement cavity 9 should be located between the touch base 10 and the sliding base 1.

[0062] In one embodiment of this utility model, touch elastic bumps 11 and electrode connectors 12 are provided on the touch substrate 10, wherein...

[0063] The touch elastic bump 11 and the electrode connector 12 protrude from two corresponding surfaces of the touch substrate 10, wherein the electrode connector 12 is located on the side surface of the touch substrate 10 adjacent to the sliding substrate 1.

[0064] The touch plate 13 is assembled on the plate connector 12.

[0065] Figure 5 The figure also shows an embodiment in which touch elastic bumps 11 and substrate connectors 12 are provided on the touch substrate 10. In the figure, the touch elastic bumps 11 and the electrode connectors 12 are directly opposite each other on the touch substrate 10. After the touch elastic bumps 11 are provided on the touch substrate 10, they can provide positioning and indication when touching. Both the touch elastic bumps 11 and the electrode connectors 12 are arc-shaped, so that the height of the touch elastic bumps 10 can be reduced while providing a good touch experience. The height of the touch elastic bumps 11 is generally 0.2 μm. The touch elastic bumps 11 are preferably made of skin-friendly materials, such as PDMS film. Of course, the electrode connectors 12 can also be made of the same material, so the electrode connectors 12 can also be PDMS film.

[0066] Since the electrode connector 12 can be arc-shaped, after the touch electrode 13 is disposed on the electrode connector 12, the touch electrode 13 protrudes from the touch base 10, thereby reducing the movement distance of the touch electrode 13 and improving the reliability of the touch sensor.

[0067] In one embodiment of this utility model, a touch base support unit for supporting the touch base 10 is provided on the sliding base 1, wherein...

[0068] The touch substrate support unit includes a supporting first connecting layer 16, an elastic support layer 15, and a supporting second connecting layer 14, wherein...

[0069] The first connecting layer 16 is supported on the sliding base 1, the elastic support layer 15 is on the first connecting layer 16, and the second connecting layer 14 is on the elastic support layer 15.

[0070] The touch substrate 10 is located on the supporting second connection layer 14;

[0071] The electrode plate movement cavity 9 passes through the first connecting layer 16, the elastic support layer 15, and the second connecting layer 14, so that the first electrode 6 and the second electrode 5 of the substrate are exposed through the electrode plate movement cavity 9.

[0072] As explained above, touching and pressing the touch base 10 causes the touch electrode 13 to move. Generally, after the touch electrode 13 moves, the touch base 10 needs to move synchronously. Therefore, in order to meet the movement requirements of the touch electrode 13, the touch base 10 should be supported by a touch base support unit. Figure 5 An embodiment of the touch substrate unit 10 is shown in the figure.

[0073] In specific implementation, both the first supporting connecting layer 16 and the second supporting connecting layer 14 are double-sided adhesive layers. One side of the first supporting connecting layer 16 is bonded and fixed to the sliding base 1, and the elastic supporting layer 15 can be bonded and fixed to the other side of the first supporting connecting layer 16. Using the same method, the connection between the elastic supporting layer 15 and the second supporting connecting layer 14, as well as the corresponding connection between the touch base 10 and the second supporting connecting layer 14, can be realized.

[0074] Specifically, the elastic support layer 15 should have elastic support capability. The elastic support capability of the elastic support layer 15 can provide the reciprocating motion power of the touch electrode 13. The elastic support layer 15 is a PDMS film layer or a resin layer. Of course, the elastic support layer 15 can also be supported by other materials. The material of the elastic support layer 15 should meet the requirements of sliding touch and providing the reciprocating motion of the touch electrode 13.

[0075] Figure 5 The document also illustrates an embodiment in which a sliding substrate connecting layer 8 is provided on the sliding substrate 1. The sliding substrate connecting layer 8 can be a double-sided adhesive layer, and the sliding substrate 1 can be assembled onto the flexible carrier using the sliding substrate connecting layer 8. Of course, the sliding substrate 1 can also be assembled onto the flexible carrier in other ways, which can be selected as needed, and will not be described in detail here.
