[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0039] Reference below Figure 1-Figure 7 A touch assembly 100 according to an embodiment of the present invention is described.
[0040] like Figure 1 As shown, the touch assembly 100 according to an embodiment of the present invention includes a first substrate 10 and a membrane 20 . The membrane 20 is disposed on one side of the first substrate 10 and is connected to the first substrate 10 .
[0041] The diaphragm 20 includes a membrane body 21 and a lead portion 22, wherein the lead portion 22 is located in the area occupied by the membrane body 21. Specifically, the lead portion 22 can be located in the middle area of the area occupied by the membrane body 21. For example, the lead portion 22 can be located to the left of the area occupied by the membrane body 21, or to the right of the area occupied by the membrane body 21, or in the center of the area occupied by the membrane body 21.
[0042] According to the touch assembly 100 of the present invention, by positioning the lead portion 22 within the area occupied by the membrane body 21, the lead portion 22 is protected, preventing damage during the manufacturing process. Compared to the related art solution in which the lead portion 22 extends from one side of the membrane 20, the present invention positions the lead portion 22 within the area occupied by the membrane 20, aligning the wiring of the membrane 20 relatively centrally and ensuring a relatively uniform resistance value for each key, thereby ensuring a consistent touch effect for each key.
[0043] Therefore, the touch assembly 100 of the present application has a lower manufacturing cost, is less prone to damage, has higher reliability in use, and is more sensitive to touch.
[0044] According to some embodiments of the present invention, the membrane includes a substrate layer and at least two functional layers.
[0045] The substrate layer, serving as a printing carrier, is a thin sheet with a certain degree of structural strength. The substrate layer can be made of resins such as PET (Polyethylene terephthalate), PMMA (Polymethylmethacrylate), PC (Polycarbonate), PVC (Polyvinylchloride), PP (Polypropylene), and acrylic resin.
[0046] Part of the functional layer can be printed on the outer surface of the substrate layer, and the remaining part can be printed on the inner surface of the substrate layer. The functional layer can include a graphic layer, a circuit layer, a uniform light layer, a varnish layer, etc.
[0047] In some embodiments, the film includes a substrate layer, a graphics layer, and a circuit layer. The specific type of graphics on the graphics layer is not limited, and includes, for example, but not limited to, any type of language (e.g., Chinese characters, English letters, French letters, etc.), numbers, color combinations, patterns, and any one or any combination of graphics represented by regions of varying grayscale values. The graphics on the graphics layer can be in color or black and white, without limitation.
[0048] The circuit layer has a printed circuit, so that the circuit layer as a whole presents the form of a flexible circuit.
[0049] It should be noted that there is no limit to the printing method, including but not limited to: spraying, laser printing, brushing, etc. In short, each printed layer printed on the substrate layer itself does not have a film carrier, that is, the circuit layer itself does not have a film carrier, and the graphic layer itself does not have a film carrier. Each printed layer uses the substrate layer as a carrier, and each printed layer is printed layer by layer on the substrate layer to obtain each printed layer.
[0050] The circuit layer and the graphic layer are integrated and printed on the substrate layer, forming a whole. In this way, there is no gap between the circuit layer and the graphic layer as in the related art. In other words, the gap between the two layers in the related art can be absolutely eliminated, and the requirements for graphic display clarity after lighting can be met. In addition, air and water vapor will not penetrate between the circuit layer and the graphic layer. Therefore, it can effectively improve the problem of touch insensitivity and failure caused by moisture on the diaphragm in the related art.
[0051] In other embodiments, the membrane includes a substrate layer, a graphics layer, a circuit layer, and a light-leveling layer. The circuit layer and the graphics layer are both disposed outside the light-leveling layer. When the touch component 100 is turned on, light passes through the touch component 100 from the inside to the outside, first passing through the light-leveling layer, and then through the circuit layer and the graphics layer. As the light passes through the light-leveling layer, the light-leveling layer provides a good light-leveling effect, making the brightness of the touch component 100 more uniform and softer, and making it difficult for the user to see the light source behind the touch component 100.
[0052] The first substrate 10 can be made of a light-transmitting material so that the pattern on the pattern layer of the membrane 20 can be seen from the outside when the touch component 100 is lit. When the touch component 100 is not lit, due to the action of the first substrate 10, the pattern layer and the circuit layer are almost invisible to the outside field of view of the touch component 100. In other words, when the touch component 100 is not lit, the user can hardly see the pattern layer and the circuit layer from the outside.
[0053] like Figure 1 As shown, according to some embodiments of the present invention, the middle portion of the membrane body 21 has a first mounting hole 211, the lead portion 22 is arranged in the first mounting hole 211, and the length direction of the lead portion 22 (such as Figure 1 One end of the ferrule (in the left-right direction as shown) is connected to the hole edge of the first mounting hole 211 and the other end extends toward the direction close to the center of the first mounting hole 211.
[0054] Therefore, by setting the lead part 22 in the first mounting hole 211 of the membrane body 21, that is, setting the lead part 22 in the middle area of the membrane body 21, the outer dimensions of the membrane body 21 can be reduced, the production cost can be reduced, and the lead part 22 can be protected to prevent the lead part 22 from being damaged during the production process.
[0055] like Figure 1 As shown, according to some embodiments of the present invention, the first substrate 10 has a second mounting hole 11 for mounting a control knob, and the second mounting hole 11 corresponds to the first mounting hole 211 in position.
[0056] Therefore, by aligning the positions of the second mounting hole 11 and the first mounting hole 211 , the lead portion 22 of the diaphragm 20 and the knob can be aligned, thereby facilitating electrical connection between the two.
[0057] In some embodiments, the projection of the second mounting hole 11 on the diaphragm 20 is located inside the first mounting hole 211. For example, the first mounting hole 211 may be a square hole, a rectangular hole, or a circular hole, and the second mounting hole 11 may be a circular hole.
[0058] In the above technical solution, by setting the projection of the second mounting hole 11 on the diaphragm 20 within the first mounting hole 211, the diaphragm 20 can be prevented from blocking the second mounting hole 11, thereby preventing the diaphragm 20 from interfering with the knob and ensuring the reliability of the diaphragm 20 and the knob.
[0059] In the related art, the lead portion 22 of the diaphragm 20 is led out from its side, resulting in the need to disconnect the connection position between the mounting base and the first substrate 10. This makes it impossible to achieve a complete seal between the mounting base and the first substrate 10, posing a risk of water leakage.
[0060] like Figure 1 As shown, according to some embodiments of the present invention, the touch assembly 100 further includes a mounting seat (not shown in the figure), which is located on the side of the diaphragm 20 facing away from the first substrate 10, and the mounting seat is connected to the first substrate 10 via an annular connecting portion 12, and the diaphragm 20 is located in the area enclosed by the annular connecting portion 12.
[0061] Compared with the technical solutions of the related art, the present application arranges the lead portion 22 in the first mounting hole 211 of the membrane body 21, that is, arranges the lead portion 22 in the middle area of the membrane body 21. In this way, there is no need to lead the lead portion 22 out from the first substrate 10 and the side of the mounting seat. The connection portion between the mounting seat and the first substrate 10 can be formed as an annular connection portion 12, so that the diaphragm 20 can be arranged in the annular connection portion 12, so that the diaphragm 20 is completely enclosed between the mounting seat and the first substrate 10, thereby achieving sealing and preventing water from entering the interior of the touch component 100, which is beneficial to improving the reliability of the touch component 100.
[0062] In some embodiments, the mounting base and the first substrate 10 are connected by ultrasonic welding, and the annular connecting portion 12 is an ultrasonic welding joint.
[0063] By using ultrasonic welding to connect the mounting base and the first substrate 10, the positions of the mounting base and the first substrate 10 corresponding to the ultrasonic welding head can be melted and fused together in a short time, thereby forming a firm welding joint, which is conducive to ensuring welding strength, and can also increase welding speed and lower production costs.
[0064] like Figure 2-Figure 6 As shown, according to some embodiments of the present invention, a through hole 231 is provided on the diaphragm 20, and the touch component 100 further includes a connector 30, which is provided at the through hole 231. The connector 30 includes an anti-slip portion 31, which is located on the side of the diaphragm 20 facing away from the first substrate 10, and the projection of the anti-slip portion 31 on the diaphragm 20 is at least partially located outside the through hole 231.
[0065] In the above technical solution, by arranging the anti-detachment portion 31 on the side of the diaphragm 20 away from the first substrate 10, the diaphragm 20 and the first substrate 10 can be riveted together through the connecting member 30, so that the diaphragm 20 and the first substrate 10 are connected together, thereby reinforcing the diaphragm 20, reducing the chance of damage to the diaphragm 20 when pulled by external force, and ensuring the touch effect.
[0066] In some embodiments, the connector 30 and the first substrate 10 are integrally molded, so that the diaphragm 20 is connected to the first substrate 10. That is, during the injection molding process of the first substrate 10, the molten material can pass through the through-hole 231 from one side of the diaphragm 20 in the thickness direction and then flow to the other side of the diaphragm 20 in the thickness direction. After the molten material solidifies, the first substrate 10 and the connector 30 are formed.
[0067] Specifically, before injection molding, the diaphragm 20 and the insert can be placed in a mold, with the insert corresponding to the through hole 231 of the diaphragm 20 , and the insert and the other side of the diaphragm 20 in the thickness direction forming a cavity.
[0068] During the injection molding process, the molten resin flows to one side of the diaphragm 20 in the thickness direction, and can also pass through the through-hole 231 and flow into the mold cavity under the guidance of the insert. After the molten resin solidifies, it forms the first substrate 10 and the connector 30. Because the outer dimensions of the anti-detachment portion 31 of the connector 30 are larger than the dimensions of the through-hole 231, the diaphragm 20 and the first substrate 10 are riveted together through the connector 30, connecting the diaphragm 20 and the first substrate 10 together and strengthening the diaphragm 20.
[0069] Compared with the reinforcement method of adding welding sheets in the related art, by forming a connector 30 that is integrally injection-molded with the first substrate 10 at the through hole 231 of the diaphragm 20, on the one hand, the welding sheet structure can be eliminated, thereby reducing production costs. On the other hand, the connector 30 is integrally injection-molded with the first substrate 10, which can simplify the process, improve production efficiency, and ensure the connection stability between the diaphragm 20 and the first substrate 10. In this way, the diaphragm 20 can be reinforced, the chance of damage to the diaphragm 20 when pulled by external force can be reduced, and the touch effect can be ensured.
[0070] The connecting member 30 and the first substrate 10 are made of the same material. For example, the connecting member 30 and the first substrate 10 are both made of plastic or resin.
[0071] In the above technical solution, the connector 30 and the first substrate 10 are made of the same material. On the one hand, this can simplify the injection molding process and improve production efficiency. On the other hand, it can ensure the consistency of the structural performance of the connector 30 and the first substrate 10, thereby ensuring the connection stability between the diaphragm 20 and the first substrate 10 and improving the reliability of the touch component 100.
[0072] It should be noted that the first substrate 10 can be a translucent structure or a non-transparent structure to cover a portion of the membrane 20. The touch assembly 100 may also include a second substrate, which can be a transparent structure or a translucent structure. For example, the first substrate 10 has a mounting opening, and the second substrate is disposed at the mounting opening, and the membrane 20 is located on the same side of the first substrate 10 and the second substrate in the thickness direction.
[0073] According to some embodiments of the present invention, the diaphragm 20 includes an ITO film. The ITO film has a low resistivity and can effectively conduct current, meeting the required conductivity requirements. The ITO film also has a high visible light transmittance, ensuring good conductivity while allowing light to pass through efficiently, achieving clear image display and good optical performance.
[0074] In some embodiments, the through hole 231 is provided at a connection position between the lead portion 22 and the film body 21 .
[0075] The lead portion 22 is easily pulled when connecting or disconnecting wires or when the entire device shakes. Since the lead portion 22 is a long strip structure, the connection position between the lead portion 22 and the membrane body 21 is easily damaged by pulling, resulting in poor touch.
[0076] In the above technical solution, a through hole 231 is provided at the connection position between the lead portion 22 and the membrane body 21, and a connector 30 connected to the first substrate 10 is formed at the through hole 231, so that the connection position between the lead portion 22 and the membrane body 21 can be connected to the first substrate 10. In this way, the connection position between the lead portion 22 and the membrane body 21 of the membrane 20 can be reinforced to ensure that when the lead portion 22 is pulled by external force, the connection position between the lead portion 22 and the membrane body 21 and the first substrate 10 will not be peeled off, thereby reducing the chance of damage to the membrane 20 and ensuring the touch effect.
[0077] like Figure 3 and Figure 4 As shown, in some examples, the number of the through holes 231 is at least two, and the at least two through holes 231 are arranged in the width direction of the lead portion 22. For example, the number of the through holes 231 can be two or more.
[0078] In the example where there are two through holes 231 , the two through holes 231 are arranged in the width direction of the lead portion 22 , so that at least two positions of the lead portion 22 arranged in its width direction are connected to the first substrate 10 through two connectors 30 .
[0079] In an example where the number of through holes 231 is two or more, at least two through holes 231 can be arranged in the width direction of the lead portion 22, so that at least two positions of the lead portion 22 arranged in its width direction are connected to the first substrate 10 through two connectors 30, and at least two through holes 231 can be arranged in the length direction of the lead portion 22, so that at least two positions of the lead portion 22 arranged in its length direction are connected to the first substrate 10 through two connectors 30.
[0080] Therefore, by providing at least two through holes 231 in the width direction of the lead portion 22, the lead portion 22 can be connected to the first substrate 10 through two connectors 30 at at least two positions arranged in the width direction thereof, thereby improving the connection reliability between the first substrate 10 and the diaphragm 20, further reducing the probability of damage to the diaphragm 20, and further ensuring the touch effect of the touch component 100.
[0081] The through hole 231 may be a circular hole, and the diameter of the through hole 231 may be 2 mm to 4 mm. For example, the diameter of the through hole 231 may be 2 mm, 3 mm, or 4 mm.
[0082] like Figure 3 and Figure 4 As shown, in some examples, both sides of the lead portion 22 in the width direction have structural reinforcement portions 23 , the structural reinforcement portions 23 are connected to the membrane body 21 and the lead portion 22 , and the through holes 231 are provided in the structural reinforcement portions 23 .
[0083] The provision of the structural reinforcement portion 23 reinforces the connection between the membrane body 21 and the lead portion 22, thereby improving the connection reliability between the membrane body 21 and the lead portion 22, reducing the probability of damage to the membrane 20 when subjected to external forces, and ensuring the touch effect. Furthermore, in addition to the provision of the structural reinforcement portion 23, a through hole 231 is provided in the structural reinforcement portion 23, thereby forming a connector 30 connected to the first substrate 10 at the through hole 231. Furthermore, the structural reinforcement portion 23 can be connected to the first substrate 10, further reducing the probability of damage to the membrane 20.
[0084] In some specific examples, the structural reinforcement portion 23 is located at the angle between the membrane body 21 and the lead portion 22, and one side edge of the structural reinforcement portion 23 forms a circular transition connection with the membrane body 21 and the lead portion 22. In other words, the structural reinforcement portion 23 is generally formed in a triangular shape. By forming a circular transition connection between one side edge of the structural reinforcement portion 23 and the membrane body 21 and the lead portion 22, the connection reliability of the structural reinforcement portion 23, the membrane body 21, and the lead portion 22 can be improved, preventing the membrane 20 from tearing when subjected to external forces, further improving the structural reliability of the membrane 20, and thus improving the reliability of the touch assembly 100.
[0085] like Figure 7 As shown, according to some embodiments of the present invention, the anti-slip portion 31 includes an inner ring body 311 and an outer ring body 312 , the outer ring body 312 is sleeved on the outside of the inner ring body 311 , and the inner ring body 311 and the outer ring body 312 are connected by a connecting rib 313 .
[0086] Specifically, before injection molding, the diaphragm 20 and the insert can be placed in a mold, with the insert corresponding to the through hole 231 of the diaphragm 20, and forming a cavity with the insert and the other side in the thickness direction of the diaphragm 20. During the injection molding process, the molten resin flows to one side in the thickness direction of the diaphragm 20, and can also pass through the through hole 231 and flow into the cavity under the guidance of the insert. After the molten resin in the cavity solidifies, the inner ring body 311, outer ring body 312 and connecting ribs 313 of the anti-slip portion 31 are formed, and the outer ring body 312 and connecting ribs 313 are connected to the diaphragm 20, so that the diaphragm 20 is connected to the first substrate 10.
[0087] Since the projection of the anti-slip portion 31 on the diaphragm 20 is at least partially located outside the through hole 231, that is, the size of the anti-slip portion 31 is relatively large, shrinkage problems may occur during the injection molding process. In order to prevent shrinkage problems during the injection molding process and ensure the appearance of the anti-slip portion 31, the present application reduces the size of the various structural parts of the anti-slip portion 31 by setting the anti-slip portion 31 to include an inner ring body 311, an outer ring body 312 and a connecting rib 313. This can avoid shrinkage during the injection molding process, thereby ensuring the shape of the anti-slip portion 31, thereby ensuring the connection stability of the diaphragm 20 and the first substrate 10, reducing the probability of damage to the diaphragm 20 when pulled by external force, and ensuring the touch effect.
[0088] like Figure 7 As shown, in some embodiments, there are multiple connecting ribs 313, which are arranged at intervals along the circumference of the inner ring body 311, and a through hole 3131 is provided between two adjacent connecting ribs 313. By providing multiple connecting ribs 313, the connection reliability between the inner ring body 311 and the outer ring body 312 can be ensured, thereby ensuring the structural strength of the anti-detachment portion 31 and preventing deformation of the anti-detachment portion 31.
[0089] like Figure 5 and Figure 6 As shown, in some embodiments, the connecting ribs 313 and the outer ring body 312 are both connected to the diaphragm 20. The diaphragm 20 is not only riveted to the first substrate 10 via the connector 30, but the connecting ribs 313 and the outer ring body 312 of the anti-detachment portion 31 are also connected to the diaphragm 20, so that the anti-detachment portion 31 is connected to the diaphragm 20 at the through hole 231, thereby further improving the connection reliability between the first substrate 10 and the diaphragm 20, significantly reducing the probability of damage to the diaphragm 20, and thus ensuring the touch effect of the touch component 100.
[0090] In some embodiments, the outer diameter of the inner ring body 311 is smaller than the aperture of the through hole 231. This prevents the insert from completely blocking the through hole 231 of the diaphragm 20 during injection molding, ensuring that the molten resin can flow from one side of the diaphragm 20 in the thickness direction, through the through hole 231, to the other side of the diaphragm 20 in the thickness direction, thereby forming the connector 30.
[0091] Specifically, if Figure 7 As shown, the width L1 of the inner ring body 311 and the width L2 of the outer ring body 312 are both 0.5-1.5 mm, the outer diameter D1 of the inner ring body 311 is 2-4 mm, the outer diameter D2 of the outer ring body 312 is 5-7 mm, and the width L3 of the connecting rib 313 is 0.5-1.5 mm.
[0092] For example, the width L1 of the inner ring body 311 and the width L2 of the outer ring body 312 can be 0.5mm, 1mm or 1.5mm, the outer diameter D1 of the inner ring body 311 can be 2mm, 2.8mm, 3mm or 4mm, the outer diameter D2 of the outer ring body 312 can be 5mm, 6mm or 7mm, the width L3 of the connecting rib 313 can be 0.5mm, 0.8mm, 1mm or 1.5mm, and the number of connecting ribs 313 can be 3, 4, etc.
[0093] like Figure 6 As shown, according to some embodiments of the present invention, the connector 30 further includes a connecting column 32 , which is passed through the through hole 231 , one end of the connecting column 32 is connected to the first substrate 10 and the other end is connected to the anti-detachment portion 31 .
[0094] That is to say, the anti-slip portion 31, the connecting column 32 and the first substrate 10 are integrally injection molded. The injection-molded connecting column 32 can connect the anti-slip portion 31 with the first substrate 10, thereby connecting the diaphragm 20 to the first substrate 10, reducing the chance of damage to the diaphragm 20 when pulled by external force, and ensuring the touch effect.
[0095] A specific embodiment of the touch assembly 100 is described below with reference to the accompanying drawings.
[0096] like Figure 1-Figure 7 As shown, the touch assembly 100 includes a first substrate 10 , a membrane 20 , a connector 30 and a mounting seat.
[0097] The first substrate 10 can be a non-transparent structure or a translucent structure. The first substrate 10 is provided with a second mounting hole 11 for mounting the knob.
[0098] The diaphragm 20 includes a membrane body 21 and a lead portion 22. The middle part of the membrane body 21 has a first mounting hole 211, and the lead portion 22 is arranged in the first mounting hole 211. The length direction of the lead portion 22 extends along the length direction of the membrane body 21. One end of the lead portion 22 in the length direction is connected to the membrane body 21, and the other end of the lead portion 22 in the length direction extends toward the center of the first mounting hole 211. Both sides of the lead portion 22 in the width direction have structural reinforcement portions 23 respectively. The shape of the structural reinforcement portion 23 is roughly triangular. The structural reinforcement portion 23 is located in the angle area between the membrane body 21 and the lead portion 22, and the structural reinforcement portion 23 is connected to the membrane body 21 and the lead portion 22 in a circular arc transition, respectively. The structural reinforcement portion 23 is provided with a through hole 231.
[0099] The diaphragm 20 is provided on one side of the first substrate 10 in the thickness direction. The first mounting hole 211 on the diaphragm 20 corresponds to and is connected to the second mounting hole 11 on the first substrate 10 , thereby facilitating electrical connection between the lead portion 22 and the knob.
[0100] The connecting member 30 includes an anti-slip portion 31 and a connecting column 32. The anti-slip portion 31 includes an inner ring body 311, an outer ring body 312 and a plurality of connecting ribs 313. The outer ring body 312 is sleeved on the outside of the inner ring body 311. The plurality of connecting ribs 313 are arranged at intervals in the circumferential direction of the inner ring body 311. The two ends of each connecting rib 313 are respectively connected to the inner ring body 311 and the outer ring body 312. One end of the connecting column 32 is connected to the first substrate 10 and the other end is connected to the inner ring body 311.
[0101] Before injection molding, the diaphragm 20 and the insert can be placed in the mold. The insert is arranged opposite to the through hole 231 on the diaphragm 20 , and a cavity is formed between the insert and the diaphragm 20 .
[0102] During the injection molding process, the molten resin flows to one side of the thickness direction of the diaphragm 20, and can also pass through the through hole 231 and flow into the mold cavity under the guidance of the insert. After the molten resin is solidified, the first substrate 10 and the connector 30 are formed. Since the external size of the anti-detachment part 31 of the connector 30 is larger than the aperture of the through hole 231, it can prevent the diaphragm 20 from detaching from the first substrate 10, and the diaphragm 20 can be connected to the first substrate 10.
[0103] The mounting seat is located on a side of the diaphragm 20 facing away from the first substrate 10. The mounting seat and the first substrate 10 can be connected via an annular connecting portion 12. The diaphragm 20 is located between the mounting seat and the first substrate 10, and the annular connecting portion 12 surrounds the diaphragm 20. This forms a relatively sealed structure for the touch assembly 100, preventing external moisture from entering the touch assembly 100 and ensuring the reliability of the touch assembly 100.
