[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following is for reference. Figures 1-7 A touch component 100 according to an embodiment of the present invention is described.

[0040] like Figure 1 As shown, the touch component 100 according to an embodiment of the present invention includes a first substrate 10 and a diaphragm 20. The diaphragm 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, with the lead portion 22 located within the area occupied by the membrane body 21. Specifically, the lead portion 22 can be located in the central region of the area occupied by the membrane body 21. For example, the lead portion 22 can be located slightly to the left, slightly to the right, or in the center of the area occupied by the membrane body 21.

[0042] According to an embodiment of the present invention, the touch component 100 protects the lead portion 22 by placing it within the area occupied by the membrane body 21, preventing damage to the lead portion 22 during manufacturing. Compared with the related art, where the lead portion 22 extends from one side of the membrane 20, this application places the lead portion 22 within the area occupied by the membrane 20, making the traces of the membrane 20 relatively centered and the resistance value of each button relatively uniform, thereby ensuring the touch effect of each button.

[0043] Therefore, the touch component 100 of this application has a lower manufacturing cost, is less prone to damage, has higher reliability, 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 the printing carrier, is a thin sheet with a certain structural strength. The raw materials for the substrate layer can be resins such as PET (Polyethylene terephthalate), PMMA (Polymethylmethacrylate), PC (Polycarbonate), PVC (Polyvinylchloride), PP (Polypropylene), and acrylic resin.

[0046] A portion of the functional layer can be printed on the outer surface of the substrate layer, while the remainder is printed on the inner surface of the substrate layer. Functional layers may include pattern layers, circuit layers, homogenizing layers, and varnish layers.

[0047] In some embodiments, the diaphragm includes a substrate layer, a pattern layer, and a circuit layer. The specific type of pattern on the pattern layer is not limited, and includes, but is not limited to: any kind of language text (e.g., Chinese characters, English letters, French letters, etc.), numbers, color combinations, patterns, and any combination of patterns presented by regions with different grayscale values. The pattern on the pattern layer can be in color or in black and white, without limitation.

[0048] The circuit layer has printed circuits, giving the entire circuit layer a flexible circuit shape.

[0049] It should be noted that the printing method is not limited, such as including but not limited to: spraying, laser printing, brushing, etc. In short, each printed layer printed on the substrate layer does not have a film carrier itself, 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 is printed layer by layer on the substrate layer to obtain each printed layer.

[0050] By integrating and printing the circuit layer and the graphic layer onto the substrate layer, they are combined into one unit. In this way, there is no gap between the circuit layer and the graphic layer as in related technologies. That is to say, the gap between the two in related technologies can be completely eliminated, which can meet the requirements of graphic display clarity after lighting. In addition, air and moisture 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 in the film in related technologies.

[0051] In other embodiments, the diaphragm includes a substrate layer, a pattern layer, a circuit layer, and a light-diffusing layer. The circuit layer and pattern layer are both disposed outside the light-diffusing layer. When the touch component 100 is illuminated, light passes through the touch component 100 from the inside to the outside, first passing through the light-diffusing layer, then through the circuit layer and the pattern layer. During the passage of light through the light-diffusing layer, the light-diffusing layer provides a good light-diffusing effect, resulting in a more uniform and softer brightness of the touch component 100, 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 when the touch component 100 is lit, the pattern on the pattern layer of the film 20 can be seen from the outside. When the touch component 100 is not lit, the pattern layer and circuit layer are hardly visible from the outside view of the touch component 100 under the action of the first substrate 10. In other words, when it is not lit, the user can hardly see the pattern layer and circuit layer from the outside.

[0053] like Figure 1 As shown, according to some embodiments of the present invention, the membrane body 21 has a first mounting hole 211 in the middle, and the lead wire portion 22 is disposed in the first mounting hole 211. The length direction of the lead wire portion 22 (e.g., Figure 1 One end of the device (in the left-right direction shown) is connected to the edge of the first mounting hole 211, and the other end extends toward the center of the first mounting hole 211.

[0054] Therefore, by placing the lead wire portion 22 inside the first mounting hole 211 of the membrane body 21, that is, placing the lead wire portion 22 in the middle region of the membrane body 21, the external size of the membrane body 21 can be reduced, the manufacturing cost can be reduced, and the lead wire portion 22 can also be protected to prevent damage to the lead wire portion 22 during the manufacturing 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 position of the first mounting hole 211.

[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 can be aligned with the knob position, facilitating the electrical connection between the two.

[0057] In some embodiments, the projection of the second mounting hole 11 onto the diaphragm 20 is located within the first mounting hole 211. For example, the first mounting hole 211 can be a square hole, a rectangular hole, or a round hole, and the second mounting hole 11 can be a round 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 interference between the diaphragm 20 and the knob and ensuring the reliability of the diaphragm 20 and the knob.

[0059] In related technologies, the lead portion 22 of the diaphragm 20 is led out from its side, which requires the connection between the mounting base and the first substrate 10 to be disconnected. This makes it impossible to completely seal the mounting base and the first substrate 10, and there is a risk of water leakage.

[0060] like Figure 1 As shown, according to some embodiments of the present invention, the touch component 100 further includes a mounting base (not shown in the figure), the mounting base is located on the side of the diaphragm 20 away from the first substrate 10, the mounting base is connected to the first substrate 10 by 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 related technologies, this application sets the lead wire portion 22 in the first mounting hole 211 of the membrane body 21, that is, sets the lead wire portion 22 in the middle region of the membrane body 21. In this way, it is not necessary to lead the lead wire portion 22 out from the side of the first substrate 10 and the mounting seat. The connection between the mounting seat and the first substrate 10 can be formed into an annular connection portion 12, so that the membrane 20 can be set in the annular connection portion 12, so that the membrane 20 is completely sealed between the mounting seat and the first substrate 10, achieving a seal 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 connection portion 12 is an ultrasonic welding joint. The mounting base and the first substrate 10 can be made of the same material.

[0063] By using ultrasonic welding to connect the mounting base and the first substrate 10 together, the mounting base and the first substrate 10 can melt and fuse together at the positions corresponding to the ultrasonic welding head in a short time, thereby forming a strong welded joint. This helps to ensure welding strength, increases welding speed, and reduces production costs.

[0064] like Figures 2-6 As shown, according to some embodiments of the present invention, the diaphragm 20 is provided with a through hole 231, and the touch assembly 100 further includes a connector 30, which is disposed at the through hole 231. The connector 30 includes an anti-detachment portion 31, which is located on the side of the diaphragm 20 away from the first substrate 10. The projection of the anti-detachment portion 31 on the diaphragm 20 is at least partially located outside the through hole 231.

[0065] In the above technical solution, by setting the anti-detachment part 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 by the connector 30, so that the diaphragm 20 and the first substrate 10 are connected together, which strengthens the diaphragm 20, reduces the probability of damage when the diaphragm 20 is pulled by external force, and ensures the touch effect.

[0066] In some embodiments, the connector 30 and the first substrate 10 are integrally injection molded parts, so that the diaphragm 20 is connected to the first substrate 10. That is, during the injection molding process, the molten material can pass through the through hole 231 from one side of the thickness direction of the diaphragm 20 and then flow to the other side of the thickness direction of the diaphragm 20. 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 into the mold, with the insert corresponding to the through hole 231 of the diaphragm 20, and the insert forming a cavity on the other side of the diaphragm 20 in the thickness direction.

[0068] During injection molding, the molten resin flows to one side of the diaphragm 20 in the thickness direction and can also pass through the through hole 231. Under the guidance of the insert, it flows into the cavity. After the molten resin solidifies, it forms the first substrate 10 and the connector 30. Since the external dimension of the anti-detachment part 31 of the connector 30 is larger than the dimension of the through hole 231, it is equivalent to riveting the diaphragm 20 and the first substrate 10 through the connector 30, thus connecting the diaphragm 20 and the first substrate 10 together and reinforcing the diaphragm 20.

[0069] Compared with the reinforcement method of adding solder pads in related technologies, forming a connector 30 integrally injection molded with the first substrate 10 at the through hole 231 of the diaphragm 20 can eliminate the need for solder pad structure, thereby reducing production costs. On the other hand, the integral injection molding of the connector 30 with the first substrate 10 can simplify the process, improve production efficiency, and ensure the connection stability between the diaphragm 20 and the first substrate 10. This can reinforce the diaphragm 20, reduce the probability of damage when the diaphragm 20 is subjected to external force, and ensure the touch effect.

[0070] The connector 30 and the first substrate 10 are made of the same material. For example, both the connector 30 and the first substrate 10 are 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, the injection molding process can be simplified and the production efficiency can be improved. On the other hand, the structural performance of the connector 30 and the first substrate 10 can be guaranteed, 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 semi-transparent structure or a non-transparent structure to cover a portion of the diaphragm 20. The touch assembly 100 may also include a second substrate, which can be a transparent structure or a semi-transparent structure. For example, the first substrate 10 has a mounting opening, the second substrate is disposed at the mounting opening, and the diaphragm 20 is located on the same side of the thickness direction of the first substrate 10 and the second substrate.

[0073] According to some embodiments of the present invention, the diaphragm 20 includes an ITO film. The ITO film has a low resistivity, which can effectively conduct current and meet the required conductivity performance. In addition, the ITO film has a high visible light transmittance, which can allow light to pass through efficiently while ensuring good conductivity, thereby achieving clear image display and good optical performance.

[0074] In some embodiments, a through hole 231 is provided at the connection position between the lead portion 22 and the membrane body 21.

[0075] The lead wire section 22 is easily pulled when connecting or disconnecting wires or when the whole machine shakes. Since the lead wire section 22 is a long strip structure, the connection between the lead wire section 22 and the membrane body 21 is easily damaged by pulling, resulting in poor contact.

[0076] In the above technical solution, by providing a through hole 231 at the connection position between the lead portion 22 and the membrane body 21, and forming a connector 30 at the through hole 231 to connect with the first substrate 10, the connection position between the lead portion 22 and the membrane body 21 can be connected to the first substrate 10. This can reinforce the connection position between the lead portion 22 and the membrane body 21 of the membrane 20, ensuring that the connection position between the lead portion 22 and the membrane body 21 will not be separated from the first substrate 10 when the lead portion 22 is pulled by external force, reducing the probability 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 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 through holes 231 can be two or more.

[0078] In an example where there are two through holes 231, the two through holes 231 are arranged in the width direction of the lead portion 22, such that at least two positions of the lead portion 22 arranged in its width direction are connected to the first substrate 10 by two connectors 30.

[0079] In examples where there are two or more through holes 231, at least two through holes 231 can be arranged in the width direction of the lead portion 22, such that at least two positions of the lead portion 22 arranged in its width direction are connected to the first substrate 10 by two connectors 30. At least two through holes 231 can also be arranged in the length direction of the lead portion 22, such that at least two positions of the lead portion 22 arranged in its length direction are connected to the first substrate 10 by two connectors 30.

[0080] Therefore, by providing at least two through holes 231 in the width direction of the lead portion 22, at least two positions of the lead portion 22 arranged in the width direction can be connected to the first substrate 10 by two connectors 30, 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 thus further ensuring the touch effect of the touch component 100.

[0081] The through hole 231 can be a round hole, and the diameter of the through hole 231 can be 2mm-4mm. For example, the diameter of the through hole 231 can be 2mm, 3mm or 4mm.

[0082] like Figure 3 and Figure 4 As shown, in some examples, the lead portion 22 has structural reinforcement portions 23 on both sides in the width direction. The structural reinforcement portions 23 are connected to the membrane body 21 and the lead portion 22, and through holes 231 are provided in the structural reinforcement portions 23.

[0083] The structural reinforcement 23 strengthens the connection between the membrane body 21 and the lead wire 22, thereby improving the connection reliability and reducing the likelihood of damage to the membrane 20 under external pulling force, ensuring a smooth touch experience. Furthermore, by providing a through hole 231 on the structural reinforcement 23, a connector 30 can be formed at the through hole 231 to connect to the first substrate 10. This further connects the structural reinforcement 23 to the first substrate 10, further reducing the likelihood of damage to the membrane 20.

[0084] In some specific examples, the structural reinforcement 23 is located in the angled region between the membrane body 21 and the lead wire portion 22, and one edge of the structural reinforcement 23 is connected to the membrane body 21 and the lead wire portion 22 by an arc transition. That is, the structural reinforcement 23 is roughly triangular in shape. By connecting one edge of the structural reinforcement 23 to the membrane body 21 and the lead wire portion 22 by an arc transition, the connection reliability between the structural reinforcement 23 and the membrane body 21 and the lead wire portion 22 can be improved, preventing the membrane 20 from tearing when subjected to external force, further improving the structural reliability of the membrane 20, thereby improving the reliability of the touch assembly 100 in use.

[0085] like Figure 7 As shown, according to some embodiments of the present invention, the anti-detachment part 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 the mold, with the insert corresponding to the through hole 231 of the diaphragm 20, and the insert forming a cavity on the other side of the diaphragm 20 in the thickness direction. During injection molding, the molten resin flows to one side of the diaphragm 20 in the thickness direction, and can also pass through the through hole 231, flowing into the cavity under the guidance of the insert. After the molten resin in the cavity solidifies, it forms the inner ring 311, the outer ring 312, and the connecting rib 313 of the anti-detachment part 31, and connects the outer ring 312 and the connecting rib 313 to the diaphragm 20, so that the diaphragm 20 is connected to the first substrate 10.

[0087] Since the projection of the anti-detachment part 31 onto the diaphragm 20 is at least partially located outside the through hole 231, meaning the size of the anti-detachment part 31 is relatively large, shrinkage may occur during injection molding. To prevent shrinkage during injection molding and ensure the appearance of the anti-detachment part 31, this application reduces the size of each part of the anti-detachment part 31 by configuring the anti-detachment part 31 to include an inner ring 311, an outer ring 312, and a connecting rib 313. This avoids shrinkage during injection molding, thereby ensuring the shape of the anti-detachment part 31, ensuring the connection stability between the diaphragm 20 and the first substrate 10, reducing the probability of damage to the diaphragm 20 when subjected to 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 circumferentially at intervals in the inner ring body 311, and there is a through hole 3131 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 part 31 and preventing deformation of the anti-detachment part 31.

[0089] like Figure 5 and Figure 6 As shown, in some embodiments, the connecting rib 313 and the outer ring 312 are both connected to the diaphragm 20. The diaphragm 20 is not only riveted to the first substrate 10 by the connector 30, but the connecting rib 313 and the outer ring 312 of the anti-detachment part 31 are also connected to the diaphragm 20, so that the anti-detachment part 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, greatly 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 311 is smaller than the diameter of the through hole 231. In this way, during injection molding, the insert will not completely block the through hole 231 of the diaphragm 20, 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, such as Figure 7 As shown, the width L1 of the inner ring 311 and the width L2 of the outer ring 312 are both 0.5-1.5mm, the outer diameter D1 of the inner ring 311 is 2-4mm, the outer diameter D2 of the outer ring 312 is 5-7mm, and the width L3 of the connecting rib 313 is 0.5-1.5mm.

[0092] For example, the width L1 of the inner ring 311 and the width L2 of the outer ring 312 can be 0.5mm, 1mm or 1.5mm, the outer diameter D1 of the inner ring 311 can be 2mm, 2.8mm, 3mm or 4mm, the outer diameter D2 of the outer ring 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 post 32, which passes through the through hole 231. One end of the connecting post 32 is connected to the first substrate 10 and the other end is connected to the anti-detachment part 31.

[0094] In other words, the anti-detachment part 31, the connecting post 32 and the first substrate 10 are integrally injection molded. The injection-molded connecting post 32 can connect the anti-detachment part 31 and the first substrate 10 together, thereby connecting the diaphragm 20 to the first substrate 10, reducing the probability of damage to the diaphragm 20 when it is pulled by external force, and ensuring the touch effect.

[0095] A specific embodiment of the touch component 100 is described below with reference to the accompanying drawings.

[0096] like Figures 1-7 As shown, the touch component 100 includes a first substrate 10, a diaphragm 20, a connector 30, and a mounting base.

[0097] The first substrate 10 can be either opaque or semi-transparent. The first substrate 10 has a second mounting hole 11 for mounting a knob.

[0098] The diaphragm 20 includes a membrane body 21 and a lead wire portion 22. The membrane body 21 has a first mounting hole 211 in the middle. The lead wire portion 22 is disposed in the first mounting hole 211. The length direction of the lead wire portion 22 extends along the length direction of the membrane body 21. One end of the lead wire portion 22 in the length direction is connected to the membrane body 21. The other end of the lead wire portion 22 in the length direction extends towards the center of the first mounting hole 211. The two sides of the lead wire portion 22 in the width direction have structural reinforcement portions 23. The shape of the structural reinforcement portion 23 is approximately triangular. The structural reinforcement portion 23 is located in the angle region between the membrane body 21 and the lead wire portion 22. The structural reinforcement portion 23 is connected to the membrane body 21 and the lead wire portion 22 by a circular arc transition. The structural reinforcement portion 23 is provided with a through hole 231.

[0099] The diaphragm 20 is disposed on one side of the first substrate 10 in the thickness direction. The first mounting hole 211 on the diaphragm 20 corresponds to and communicates with the second mounting hole 11 on the first substrate 10, thereby facilitating the electrical connection between the lead wire 22 and the knob.

[0100] The connector 30 includes an anti-detachment part 31 and a connecting post 32. The anti-detachment part 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 circumferentially at intervals in 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 post 32 is connected to the first substrate 10 and the other end is connected to the inner ring body 311.

[0101] Before injection molding, a diaphragm 20 and an insert can be placed inside the mold. The insert is positioned 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 diaphragm 20 in the thickness direction and can also pass through the through hole 231. Under the guidance of the insert, it flows into the cavity. After the molten resin solidifies, it forms the first substrate 10 and the connector 30. 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 connect the diaphragm 20 to the first substrate 10.

[0103] The mounting base is located on the side of the diaphragm 20 away from the first substrate 10. The mounting base and the first substrate 10 can be connected by the annular connecting part 12. The diaphragm 20 is located between the mounting base and the first substrate 10 and the annular connecting part 12 surrounds the diaphragm 20, thus forming 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.
