DETAILED DESCRIPTION

[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] As mentioned in the background technology, in the related technology, the touch panel includes a stacked touch panel, a printed circuit board, a pressure sensor, etc., and the printed circuit board is integrated with touch components such as MCU (Microcontroller Unit, microcontroller module), capacitor components, resistors, boost circuits, etc.

[0049] However, the stacking arrangement of related components in the touch panel will cause the touch panel to be thicker as a whole, thereby affecting the thickness of the electronic device.

[0050] In view of the above problems existing in the prior art, the present invention provides a touch panel, a touch housing assembly and an electronic device. The touch panel includes a touch sensing assembly and a touch component. The touch sensing assembly has an extension portion, which is located on one side of the touch sensing assembly. The touch component is electrically connected to the extension portion, and the touch component is used to be electrically connected to a control module of the electronic device. By installing the touch component on the extension portion, the touch component is avoided from being integrated on the touch sensing assembly, which can effectively reduce the stacking thickness of the touch panel, thereby reducing the thickness of the electronic device.

[0051] The following is an introduction to exemplary application scenarios of the present invention.

[0052] The touch panel provided by the present invention can be applied to electronic devices, such as laptop computers, desktop computers, tablet computers, virtual reality devices, vehicle-mounted front-end devices, fixed terminals or foldable devices, etc. Specifically, the touch panel provided by the present invention has a small stacking thickness, which can further reduce the thickness of the electronic device.

[0053] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0054] Reference Figures 2 to 4 As shown, the touch panel 100 provided in the embodiment of the present application includes a touch sensing component 110 and a touch component 120 .

[0055] The touch sensing assembly 110 has an extension portion 130 , which is located at one side of the touch sensing assembly 110 . The touch control component 120 is electrically connected to the extension portion 130 , and the touch control component 120 is used to be electrically connected to a control module of the electronic device.

[0056] It can be understood that the touch panel 100 provided in the embodiment of the present application can be set in an electronic device, which can be a laptop computer, a desktop computer, a tablet computer, a virtual reality device, a vehicle-mounted front-end, a fixed terminal or a foldable device, etc.

[0057] When the user touches or presses the touch sensing component 110 , the touch sensing component 110 can sense the position and movement of the user's finger and output corresponding touch sensing signals and pressure sensing signals to the touch control element 120 .

[0058] After receiving the touch sensing signal and the pressure sensing signal, the touch control component 120 sends instructions to the control module of the electronic device to enable the electronic device to perform corresponding operations, such as moving a cursor, scrolling a page, or performing a click operation.

[0059] Among them, one side of the touch sensing component 110 extends outward to form an extension portion 130. By installing the touch component 120 on the extension portion 130, the touch component is prevented from being integrated on the touch sensing component 110, which can effectively reduce the stacking thickness of the touch panel 100 and further reduce the thickness of the electronic device.

[0060] For example, for a laptop computer, the touch sensing assembly 110 can be disposed on a C-shell, and the extension portion 130 and the touch component 120 can be disposed in a cavity formed by the C-shell and the D-shell, so as to reduce the thickness of the laptop computer.

[0061] It is understandable that the touch control component 120 may include but is not limited to an MCU (Microcontroller Unit), a capacitor component, a resistor, a boost circuit, etc. The touch control component 120 may be disposed on the extension portion 130 by using SMT technology (Surface Mount Technology).

[0062] Reference Figure 3 As shown, in some embodiments, the touch sensing component 110 includes a touch panel 111 , a touch circuit layer 112 and a pressure sensing layer 113 .

[0063] The touch circuit layer 112 is disposed between the touch panel 111 and the pressure sensing layer 113 . The touch circuit layer 112 is electrically connected to the pressure sensing layer 113 . The extension portion 130 is formed by extending the touch circuit layer 112 outward.

[0064] In the above embodiment, when the user touches or presses the touch panel 111 , the touch circuit layer 112 can sense the position and movement of the user's finger and output a corresponding touch sensing signal to the touch component 120 .

[0065] The pressure sensing layer 113 is disposed on a side of the touch circuit layer 112 away from the touch panel 111 . When a user presses the touch panel 111 , the pressure sensing layer 113 detects the pressing action and outputs a corresponding pressure sensing signal to the touch component 120 through the touch circuit layer 112 .

[0066] After receiving the touch sensing signal and the pressure sensing signal, the touch control component 120 sends instructions to the control module of the electronic device to enable the electronic device to perform corresponding operations, such as moving a cursor, scrolling a page, or performing a click operation.

[0067] By way of example, the pressure sensing layer 113 may include, but is not limited to, a capacitive pressure sensing element, a resistive pressure sensing element, and the like.

[0068] The touch circuit layer 112 may include but is not limited to FPC (Flexible Printed Circuit), PCB (Printed Circuit Board), etc.

[0069] In some embodiments, the extension portion 130 is configured to be bendable relative to the touch circuit layer 112 .

[0070] In the above embodiment, the touch component 120 is electrically connected to the extension portion 130, and the extension portion 130 is flexible and can be bent relative to the touch circuit layer 112, so that the touch component 120 and the extension portion 130 can adapt to the installation environment inside the housing of the electronic device, thereby improving the compactness and reliability of the electronic device.

[0071] Exemplarily, the extension portion 130 may be a flexible circuit structure, which may include a conductive layer (eg, copper-based), a covering layer, and the like.

[0072] In some specific embodiments, the touch circuit layer 112 may be a flexible circuit board.

[0073] In the above embodiment, the flexible circuit board (FPC) is thinner than the conventional printed circuit board (PCB), which can effectively reduce the overall thickness of the touch panel 100, making it thinner and more compact.

[0074] The substrate of flexible circuit board (FPC) is usually a flexible film material, such as polyimide (PI) and polyester (PET), and the thickness of flexible circuit board (FPC) is usually 0.05mm to 0.2mm. In contrast, the substrate of printed circuit board (PCB) is usually epoxy glass cloth (FR4), and the thickness of flexible circuit board (FPC) is generally 0.2mm to 2mm.

[0075] Preferably, the touch circuit layer 112 may be a double-sided flexible circuit board. The double-sided flexible circuit board has two layers of circuits arranged on the substrate of the flexible circuit board. The double-layer circuit design allows more circuits to be arranged in a limited space, so that the overall structure of the touch panel 100 is more compact.

[0076] The thickness of the flexible circuit board may be 0.12 mm to 0.18 mm. For example, the thickness of the flexible circuit board may be 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm or 0.18 mm, etc., which is not limited to the above examples in the present application.

[0077] In some embodiments, the pressure sensing layer 113 may be a piezoelectric film.

[0078] In the above embodiment, the piezoelectric film can output a pressure sensing signal according to the pressure applied by the user on the touch panel 111, so that the electronic device performs a corresponding operation, such as performing a click operation.

[0079] The piezoelectric film is thinner than conventional pressure sensors, which can effectively reduce the overall thickness of the touch panel 100, making it thinner and more compact.

[0080] In the related art, some touch panels 100 use a mechanical metal dome switch (Domekey), which is composed of a dome metal sheet, conductive glue, and a circuit board. When touching, the user applies pressure, causing the dome metal sheet to bend downward and contact the conductive area on the circuit board, thereby completing the circuit closure and triggering key input. When the metal dome switch is used, it is usually accompanied by a mechanical impact or bending sound.

[0081] Piezo film relies on the piezoelectric effect, whereby the material generates an electrical charge when pressure is applied, triggering operation directly through induction. This works without any mechanical contact or moving parts, so there is no knocking, rebounding or friction, which in turn avoids the generation of noise.

[0082] The thickness of the piezoelectric film may be 0.08 mm to 0.12 mm. For example, the thickness of the piezoelectric film may be 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm or 0.12 mm, etc., which is not limited to the above examples in the present application.

[0083] Reference Figures 2 to 4 As shown, in some embodiments, the touch panel 111 and the touch circuit layer 112 are connected via a first adhesive layer 114 .

[0084] In the above embodiment, the touch panel 111 and the touch circuit layer 112 are fixedly connected via the first adhesive layer 114 , which can ensure the connection reliability between the touch panel 111 and the touch circuit layer 112 and prevent the touch panel 111 and the touch circuit layer 112 from being separated from each other.

[0085] The first adhesive layer 114 may include but is not limited to optically clear adhesive (OCA), pressure-sensitive adhesive (PSA), and the like.

[0086] The thickness of the first adhesive layer 114 may be 0.10 mm to 0.14 mm. For example, the thickness of the first adhesive layer 114 may be 0.10 mm, 0.12 mm, 0.13 mm or 0.14 mm, etc., which is not limited in the present embodiment and is not limited to the above examples.

[0087] Reference Figures 2 to 4 As shown, in some embodiments, a second adhesive layer 115 is disposed on a side of the pressure sensing layer 113 facing away from the touch circuit layer 112 for mounting on a housing of an electronic device.

[0088] In the above embodiment, the second adhesive layer 115 can be used to adhere the touch panel 100 of the embodiment of the present application to the housing of the electronic device.

[0089] For example, for a laptop computer, a mounting groove 220 recessed toward the D shell can be provided on the C shell of the laptop computer, so that the touch panel 100 can be installed in the mounting groove 220 through the second adhesive layer 115. In this way, the touch panel 100 does not need to be provided with a substrate, and the pressure sensing layer 113, the touch circuit layer 112 and the touch panel 111 are sequentially supported by the bottom end of the mounting groove 220, which has a simple structure and can also reduce the overall thickness.

[0090] Among them, in conventional technology, a cutout is usually made on the C-shell, and the touch panel 100 is inserted into the cutout. The cutout on the C-shell will weaken the structural strength of the C-shell to a certain extent. When the touch panel 100 is installed on the cutout, it often has fewer supporting points, especially in the case of asymmetry or uneven force, which easily leads to instability of the touch panel 100. This not only affects the responsiveness of the touch panel 100, but may also cause looseness or positional displacement between the touch panel 100 and the C-shell.

[0091] By providing the mounting groove 220 on the C shell and being recessed toward the D shell, the structural strength of the C shell can be enhanced, and after the touch panel 100 is assembled, the overall structure is more stable.

[0092] The second adhesive layer 115 may include but is not limited to optically clear adhesive (OCA), pressure-sensitive adhesive (PSA), and the like.

[0093] The thickness of the second adhesive layer 115 may be 0.10 mm to 0.14 mm. For example, the thickness of the second adhesive layer 115 may be 0.10 mm, 0.12 mm, 0.13 mm or 0.14 mm, etc., which is not limited to the above examples in the present application.

[0094] In some embodiments, the material of the touch panel 111 may include but is not limited to glass and Mylar.

[0095] The thickness of the touch panel 111 may be 0.20 mm to 0.50 mm. For example, the thickness of the touch panel 111 may be 0.20 mm, 0.30 mm, 0.40 mm or 0.50 mm, etc., which is not limited to the above examples in the present application.

[0096] In a specific embodiment, the touch panel 111 can be made of 0.4mm glass material (or 0.25mm polyester material), the first adhesive layer 114 can be made of 0.125mm optically transparent glue (or 0.1mm pressure-sensitive glue), the thickness of the touch circuit layer 112 can be 0.14mm, the thickness of the piezoelectric film can be 0.1mm, and the second adhesive layer 115 can be made of 0.125mm optically transparent glue (or 0.1mm pressure-sensitive glue), so that the thickness of the entire touch panel 100 does not exceed 0.89mm.

[0097] Reference Figures 1 to 5 As shown, the touch housing assembly 200 provided in the present application includes a housing body 210 and the above touch panel 100 , and the touch panel 100 is disposed on the housing body 210 .

[0098] In the above structural setting, since the touch housing assembly 200 adopts the touch panel 100 in the above embodiment, it also has the advantages and benefits brought by the above touch panel 100, that is, the thickness is thinner.

[0099] In some embodiments, reference Figure 5 As shown, the housing body 210 includes a first shell 211 and a second shell 212 .

[0100] The first shell 211 and the second shell 212 are arranged to form a receiving cavity 213 . The receiving cavity 213 is used to install components of the electronic device. The touch panel 100 is disposed on the first shell 211 .

[0101] In the above embodiment, the accommodating cavity 213 formed by the first shell 211 and the second shell 212 can be used to install components of the electronic device, such as a control module, a speaker assembly, etc. The touch panel 100 is disposed on the first shell 211 and can be electrically connected to the control module.

[0102] Reference Figure 1 and Figure 5 As shown, in some embodiments, a mounting groove 220 is disposed on the first housing 211 , and the touch sensing component 110 is disposed in the mounting groove 220 .

[0103] A through hole 230 is defined in the first housing 211 , and the extending portion 130 of the touch panel 100 is disposed in the accommodating cavity 213 via the through hole 230 .

[0104] In the above embodiment, the touch sensing component 110 is installed in the installation groove 220 of the first shell 211, which can ensure the stability of the assembly of the touch sensing component 110 and the first shell 211. In addition, by arranging the extension portion 130 inside the accommodating cavity 213, the internal space of the accommodating cavity 213 can be better utilized to achieve the effect of thinning the touch panel 100 and the housing body 210.

[0105] For example, for a laptop computer, the first housing 211 may be a C housing, and the second housing 212 may be a D housing. A mounting groove 220 recessed toward the D housing may be formed on the C housing by stamping or CNC processing, which may enhance the structural strength of the C housing, and after the touch panel 100 is assembled, the overall structure is more stable. In addition, a through hole 230 is provided on the C housing, so that the extension 130 and the touch component 120 are placed in the cavity formed by the C housing and the D housing.

[0106] Reference Figure 1 and Figure 5 As shown, in some specific embodiments, a mounting cavity 240 is provided on a side of the first shell 211 facing the second shell 212 , the mounting cavity 240 is communicated with the through hole 230 , and the extension portion 130 is disposed in the mounting cavity 240 .

[0107] In the above embodiment, the installation cavity 240 mainly provides an independent installation space for the touch component 120 and the extension portion 130 to avoid interference or collision with other components inside the electronic device (such as batteries, circuit boards, speakers, etc.) to ensure that all components can work normally.

[0108] For example, for a notebook computer, the mounting cavity 240 may be disposed on a side of the C shell facing the D shell.

[0109] Reference Figure 1 and Figure 5 As shown, in some specific embodiments, the mounting groove 220 is opened toward a side away from the second housing 212 .

[0110] In the above embodiment, this can facilitate the installation of the touch sensing component 110 .

[0111] The electronic device provided in the present application includes a device body and the above touch control housing assembly 200 , wherein the device body is disposed on the touch control housing assembly 200 .

[0112] In the above structural setting, since the electronic device adopts the touch housing assembly 200 in the above embodiment, it also has the advantages and benefits brought by the above touch housing assembly 200, which will not be further described here.
