The embodiments of this application can be implemented in many ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the embodiments of this application are not limited to the specific embodiments disclosed below.
[0056] It is understood that the terms "first," "second," etc., used in this application may be used to describe various technical terms, but should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0060] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application and in its specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0061] Figure 1 A schematic diagram of the structure of a game controller 10 in one embodiment of the related technology is shown; Figure 2 It shows Figure 1 A magnified schematic diagram of the structure at point M; for ease of explanation, only the content related to the relevant technical embodiments is shown.
[0062] Please refer to Figure 1 and Figure 2One embodiment of the related technology provides a game controller 10, on which the patterns of the buttons 11 are fixed patterns printed on the surface. When a user switches from one game to another, the function corresponding to the same button 11 differs in different games due to the different operations and settings within each game. For example, taking button 11 as button "G", in a role-playing game, the function of button "G" is to attack, while in a racing game, the function of button "G" is to brake. Since the pattern on button 11 is a fixed pattern, the pattern on button 11 cannot represent the corresponding function in different games.
[0063] Figure 3 A schematic diagram of the structure of the game controller 20 in a first use state is shown in another embodiment of the related technology; Figure 4 A schematic diagram of the game controller 20 in a second usage state is shown in another embodiment of the related technology; for ease of explanation, only the content related to the embodiments of the related technology is shown.
[0064] Please refer to Figure 3 and Figure 4 In another embodiment of the related technology, a game controller 20 is provided, which includes a first part 20a and a second part 20b. Figure 3 The first usage state shown in the diagram is the state in which the first part 20a and the second part 20b are assembled on the corresponding equipment and operated. Figure 4 The second usage state illustrated is the state in which the first part 20a is used alone and in conjunction with the corresponding device. It can be seen that when switching from the first usage state to the second usage state, the orientation of the button 21 on the first part 20a changes, and at the same time, the function corresponding to the button 21 also changes (for example, the function of the same button 21 changes from confirm to cancel).
[0065] Therefore, because the button patterns are fixed, users cannot directly identify the function of each button when changing the direction in which they hold the game controller or switching games. Users must try each button to understand its function. For example, to use the pre-selection function, the user must first press and hold the button that allows pre-selection. This is extremely inconvenient for users, and the user experience needs improvement.
[0066] Based on this, to improve at least some of the aforementioned problems, embodiments of this application provide a touch input device by improving the button structure, which uses optical projection to display corresponding patterns, thus improving the problems caused by fixed patterns. The touch input device provided by embodiments of this application will be described below with reference to the accompanying drawings and some embodiments.
[0067] Figure 5 A schematic diagram of the structure of a touch input device 100 in one embodiment of this application is shown; for ease of explanation, only the content related to the embodiment of this application is shown.
[0068] In some embodiments, please refer to Figure 5 This application provides a touch input device 100, which includes a display unit 110, an optical component 120, a touch module 130, and a projection layer 140. The display unit 110 displays a pattern (i.e., the first pattern p1 shown in the figure). The optical component 120 is disposed on the display side of the display unit 110. The touch module 130 is disposed on the side of the optical component 120 facing away from the display unit 110. The touch module 130 is configured to be transparent. The projection layer 140 is disposed on the side of the touch module 130 facing the optical component 120. The optical component 120 is configured to image the pattern displayed by the display unit 110 onto the projection layer 140. The pattern imaged on the projection layer 140 is the second pattern p2 shown in the figure. Figure 5 For example, the display unit 110, optical component 120, projection layer 140 and touch module 130 are arranged sequentially along the first direction F1.
[0069] Therefore, by setting up the display unit 110, corresponding patterns can be displayed according to the control of the controller, avoiding the problem that printed patterns are fixed and difficult to change. The corresponding pattern displayed by the display unit 110 can be used to represent the function of the touch input device 100. By setting up the optical component 120 and the projection layer 140, the pattern displayed by the display unit 110 can be imaged onto the projection layer 140 and displayed with the help of the transparent touch module 130. By setting up the touch module 130, it is easy for users to identify whether it is a touch input device 100. In this way, the pattern displayed by the touch input device 100 can be changed, making it easy for users to directly know the function of the touch input device 100, facilitating user operation and improving the user experience.
[0070] In some embodiments, please continue to refer to Figure 5 The optical component 120 includes a first lens 121 and a second lens 122 spaced apart, and a pinhole 123 located between the first lens 121 and the second lens 122. Figure 5The diagram illustrates the arrangement of the first lens 121, the pinhole component 123, and the second lens 122 along a first direction F1 at intervals. It is understood that the distance between the first lens 121, the pinhole component 123, and the second lens 122 can be adjusted according to specific usage, as long as the optical component 120 can image the pattern displayed by the display unit 110 onto the projection layer 140, making it convenient for the user to see the pattern. This embodiment does not impose specific limitations in this regard. The pinhole component 123 has a pinhole 123a, which allows light to pass through, while the portion of the pinhole component 123 other than the pinhole 123a is opaque. Optionally, the color of the portion of the pinhole component 123 other than the pinhole 123a can be set to black.
[0071] Thus, by providing an optical assembly 120 including a first lens 121, a pinhole 123, and a second lens 122, it is convenient to adjust the imaging pattern process according to the usage situation.
[0072] In some embodiments, the first lens 121 is a plano-convex lens or a Fresnel lens. In other embodiments, the second lens 122 is a plano-convex lens or a Fresnel lens. That is, the type of the first lens 121 and the type of the second lens 122 can be the same or different, and can be flexibly selected according to the actual use. This application embodiment does not impose specific limitations in this regard.
[0073] In some embodiments, the focal length of the first lens 121 is 1 mm to 10 mm. In other embodiments, the focal length of the second lens 122 is 1 mm to 10 mm. That is, the focal length of the first lens 121 and the focal length of the second lens 122 can be the same or different, and can be flexibly selected according to actual use. This application embodiment does not impose specific limitations on this. When the focal length of the first lens 121 is 1 mm to 10 mm and the focal length of the second lens 122 is 1 mm to 10 mm, it can avoid the pattern displayed by the display unit 110 from being unable to be imaged on the projection layer due to the focal length of the first lens 121 being too large or too small. For example, the focal length of the first lens 121 can be 1 mm, 1.5 mm, 3 mm, 5 mm, 8 mm, 10 mm, etc., and the focal length of the second lens 122 can be 1 mm, 2.5 mm, 4 mm, 6 mm, 9 mm, 10 mm, etc.
[0074] In some embodiments, please refer to Figure 5The aperture of the pinhole 123a of the pinhole component 123 is a first size D1, which is 1 mm to 4 mm. For example, the first size D1 can be 1 mm, 1.5 mm, 1.9 mm, 2 mm, 3 mm, 4 mm, etc. In this way, the aperture of the pinhole 123a can be set in conjunction with the first lens 121 and the second lens 122 to reduce the influence of stray light (such as the light generated by the display unit 110) and obtain a pattern with the required resolution.
[0075] In some embodiments, please refer to Figure 5 The touch module 130 includes a cover plate 131 and a touch layer 132 disposed on the side of the cover plate 131 facing the optical component 120, and a projection layer 140 disposed on the side of the touch layer 132 facing away from the cover plate 131. That is, along the first direction F1, the projection layer 140, the touch layer 132, and the cover plate 131 are arranged sequentially. Optionally, the touch layer 132 is configured as an indium tin oxide conductive film, a metal mesh layer, or other transparent conductive layer. In this way, touch functionality can be achieved by setting the relevant structure of the touch module 130.
[0076] In some embodiments, the haze of the projection layer 140 is greater than 75%. This allows the pattern imaged onto the projection layer 140 to have better image quality, while also providing better opacity, making it easier for the user to view through the touch module 130. Optionally, the projection layer 140 can be made of composite PET (polyethylene glycol terephthalate) or PET with a film coating. The appropriate material can be selected according to the desired haze and image quality; this embodiment does not impose specific limitations in this regard.
[0077] In some embodiments, please continue to refer to Figure 5 The touch input device 100 also includes a mounting member 150. The mounting member 150 has a receiving cavity 151 extending along a first direction F1, and a first opening 152 and a second opening 153 opposite to each other along the first direction F1. The first opening 152 and the second opening 153 are respectively connected to the receiving cavity 151. The end of the mounting member 150 with the first opening 152 is mounted to the display side of the display unit 110, the end of the mounting member 150 with the second opening 153 is mounted to the touch module 130, and an optical component 120 is installed within the receiving cavity 151.
[0078] Optionally, the mounting component 150 can be configured as a cylindrical structure to mount the various components within the touch input device 100. The material of the mounting component 150 can be plastic, metal, or wood, depending on the actual application; this embodiment does not impose specific limitations in this regard. Further, the mounting component 150 is configured as a non-transparent component. Optionally, the color of the mounting component 150 can be set to black. This prevents diffuse reflection from occurring inside the mounting component 150, thus avoiding interference with the imaging process of the optical component 120.
[0079] In some embodiments, the optical component 120 can be mounted within the receiving cavity 151 of the mounting member 150 by means of a snap-fit or adhesive method. Figure 5 For example, the illustration shows the optical component 120 being installed in the receiving cavity 151 of the mounting member 150 via a snap-fit method. The configuration can be adjusted according to actual usage, and this embodiment does not impose specific limitations on it.
[0080] Figure 6 It shows Figure 5 A schematic diagram of the structure at point N; for ease of explanation, only the content related to the embodiments of this application is shown.
[0081] In some embodiments, please refer to Figure 6 and in conjunction with reference Figure 5 A stepped portion 154 is also provided at one end of the mounting member 150 where the second opening 153 is located. The touch module 130 and the projection layer 140 can be mounted on the mounting member 150 via the stepped portion 154. Since the projection layer 140 and the touch layer 132 have a certain thickness, it is convenient to install the touch module 130 and the projection layer 140.
[0082] In some embodiments, please continue to refer to Figure 5 The touch input device 100 also includes a spring element 160. The mounting member 150 is connected to the display unit 110 via the spring element 160. Optionally, the spring element 160 is made of silicone. This allows the user to experience the tactile sensation of pressing while performing touch operations, further enhancing the user experience.
[0083] In some embodiments, please continue to refer to Figure 5 The mounting member 150 has a second dimension D2 along the first direction F1, and the second dimension D2 is 5 mm to 25 mm. In other embodiments, please refer to... Figure 5 The dimension of the mounting part 150 along the second direction F2 is the third dimension D3, which is 3 mm to 10 mm. The second direction F2 is perpendicular to the first direction F1. Optionally, when the mounting part 150 is a cylindrical structure, the second dimension D2 is the height dimension and the third dimension D3 is the outer diameter dimension.
[0084] Therefore, by limiting the second size D2, we can avoid both excessive size that would take up too much space and insufficient size that would hinder optical imaging. Similarly, by limiting the third size D3, we can avoid both excessive size that would take up too much space and insufficient size that would hinder pressing operations.
[0085] Based on the same inventive concept, this application also provides a touch device, including a controller and a touch input device 100 as described in any of the above embodiments. The display unit 110 is capable of displaying a corresponding pattern in response to the control of the controller. Optionally, the controller may be an MCU (Microcontroller Unit). It is understood that a related program can be set in the controller to make the display unit 110 display the corresponding pattern, and the number of touch input devices 100 can be set according to actual usage. Since this touch device includes the touch input device 100 as described in any of the above embodiments, it has the advantages mentioned above, which will not be repeated here.
[0086] Based on the same inventive concept, this application also provides an electronic device including the touch device in any of the above embodiments. Since the touch device includes the touch device in any of the above embodiments, and the touch device includes the touch input device 100 in any of the above embodiments, it has the advantages mentioned above, which will not be repeated here.
[0087] It should be understood that the touch input device 100 provided in the above embodiments can be applied to fields such as mobile terminals, bionic electronics, electronic skin, wearable devices, in-vehicle devices, Internet of Things devices, and artificial intelligence devices. The aforementioned electronic devices can be mobile terminals, tablets, PDAs, iPods, smartwatches, laptops, televisions, monitors, etc. In some embodiments, the electronic device can be a game controller.
[0088] The above applications are merely a few examples of applications exemplified in this embodiment. It should be understood that the applications of the touch input device 100 are not limited to the few fields exemplified above.
[0089] In summary, this embodiment of the application, by setting up a display unit 110, can display corresponding patterns according to the control of the controller. By setting up an optical component 120 and a projection layer 140, the pattern displayed by the display unit 110 can be imaged onto the projection layer 140 and displayed using a transparent touch module 130. By setting up a touch module 130, it is easy for users to identify whether it is a touch input device 100. In this way, the pattern displayed by the touch input device 100 can be variable, making it easy for users to directly understand the function corresponding to the touch input device 100. At the same time, through the related coordination of the dimensions of the first lens 121, the second lens 122, the pinhole component 123, and the mounting component 150, a better resolution image display can be obtained. In addition, since the mounting component 150 is connected to the display unit 110 through an elastic component 160, the touch input device 100 provided in this embodiment of the application has both touch function and pressing function. Therefore, the touch input device 100 provided in this application embodiment facilitates user operation and improves the user experience through the cooperation of various components.
[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
