FIG. 1 is a schematic diagram showing a structure of a game controller 10 in an embodiment of the related art; FIG. 2 shows a schematic view of a partial enlarged structure at M in FIG. 1; for convenience of explanation, only the contents related to the related art embodiment are shown.

Referring to fig. 1 and 2, a related art game controller 10 is provided, wherein a pattern of keys 11 on the game controller 10 is a fixed pattern printed on a surface. After the user switches from one game to another, the functions corresponding to the same key 11 are different in different games due to different operations and settings in different games. For example, taking key 11 as key "G", in a role playing game the function of key "G" is attack and in a racing game the function of key "G" is brake. Since the pattern on the key 11 is a fixed pattern, the pattern on the key 11 cannot characterize the corresponding functions in different games.

Fig. 3 is a schematic diagram showing a structure of game controller 20 in a first use state according to another embodiment of the related art; fig. 4 is a schematic diagram showing a structure of game controller 20 in a second use state according to another embodiment of the related art; for convenience of explanation, only the contents related to the related art embodiment are shown.

Referring to fig. 3 and 4, another embodiment of the related art provides a game controller 20, wherein the game controller 20 includes a first portion 20a and a second portion 20b. The first use state illustrated in fig. 3 is a state in which the first portion 20a and the second portion 20b are assembled on the respective devices to operate. The second use state illustrated in fig. 4 is a state in which the first portion 20a is used alone and is engaged with the corresponding device. It can be seen that when the first usage state is switched to the second usage state, the orientation of the key 21 on the first portion 20a is changed, and at the same time, the function corresponding to the key 21 is also changed (for example, the function of the same key 21 is changed from determination to cancellation).

Therefore, since the pattern on the key is a fixed pattern, the user cannot directly learn the function corresponding to each key when the game controller is held in the hand direction or the game is switched. The user must try to operate before knowing the function corresponding to each key. For example, when using a preselected function, a key capable of being preselected must be pressed first to have the preselected function. As such, it is very inconvenient for users to use, and user experience is also to be improved.

In view of this, in order to improve at least some of the above problems, the embodiments of the present application provide a touch input device that uses optical projection to display a corresponding pattern by improving a key structure, thereby improving the above problems caused by pattern fixation. The touch input device provided in the embodiments of the present application is described below with reference to the accompanying drawings and the descriptions in some embodiments.

Fig. 5 is a schematic structural diagram of a touch input device 100 according to an embodiment of the disclosure; for ease of illustration, only matters relevant to the embodiments of the present application are shown.

In some embodiments, referring to fig. 5, a touch input device 100 is provided, and the touch input device 100 includes a display unit 110, an optical component 120, a touch module 130, and a projection layer 140. The display unit 110 is used to display a pattern (i.e., a first pattern p1 illustrated in the drawing). The optical assembly 120 is disposed on the display side of the display unit 110. The touch module 130 is disposed on a side of the optical assembly 120 facing away from the display unit 110. The touch module 130 is configured as a transparent member. The projection layer 140 is disposed on a side of the touch module 130 facing the optical component 120. The optical assembly 120 is configured to be able to image a 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 illustrated in the figure. Taking fig. 5 as an example, the display unit 110, the optical component 120, the projection layer 140, and the touch module 130 are sequentially arranged along the first direction F1.

Thus, by providing the display unit 110, a corresponding pattern can be displayed according to the control of the controller, the problem that the printed pattern is fixed and difficult to change is avoided, and the corresponding pattern displayed by the display unit 110 can be used for characterizing the corresponding function of the touch input device 100. By providing the optical component 120 and the projection layer 140, the pattern displayed by the display unit 110 can be imaged to the projection layer 140 and displayed by means of the transparent touch module 130. By providing the touch module 130, it is convenient for the user to identify whether the touch input device 100 is the one. In this way, the pattern displayed by the touch input device 100 can be changeable, so that the user can directly know the function corresponding to the touch input device 100, the user can operate conveniently, and the use experience of the user is improved.

In some embodiments, referring to fig. 5, the optical assembly 120 includes a first lens 121 and a second lens 122 disposed at intervals, and a pinhole member 123 disposed between the first lens 121 and the second lens 122. Fig. 5 illustrates a case where the first lens 121, the pinhole member 123, and the second lens 122 are sequentially arranged at intervals in the first direction F1. It is understood that the distances between the first lens 121, the pinhole element 123 and the second lens 122 may be adjusted according to the specific use situation, so long as the optical assembly 120 can image the pattern displayed by the display unit 110 onto the projection layer 140, so that the user can learn the pattern conveniently, which is not particularly limited in the embodiment of the present application. The pinhole member 123 is provided with a pinhole 123a, and the pinhole 123a is transparent, and the part of the pinhole member 123 other than the pinhole 123a is opaque. Alternatively, the color of the portion of the pinhole member 123 other than the pinhole 123a may be set to black.

In this manner, by providing the optical assembly 120 including the first lens 121, the pinhole member 123, and the second lens 122, it is convenient to adjust the process of imaging the pattern in conjunction with the use case.

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 may be the same or different, and may be flexibly selected according to the actual use situation, which is not particularly limited in the embodiment of the present application.

In some embodiments, the focal length of the first lens 121 is 1 millimeter to 10 millimeters. 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 may be the same or different, and may be flexibly selected according to the actual use situation, which is not particularly limited in the embodiment of the present application. 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 is possible to avoid that the focal lengths of the first lens 121 and the second lens 122 are too large or too small to image the pattern displayed by the display unit 110 on the projection layer. For example, the focal length of the first lens 121 may be 1 mm, 1.5 mm, 3 mm, 5 mm, 8 mm, 10 mm, etc., and the focal length of the second lens 122 may be 1 mm, 2.5 mm, 4 mm, 6 mm, 9 mm, 10 mm, etc.

In some embodiments, please continue to refer to fig. 5, the aperture of the pinhole 123a of the pinhole piece 123 is a first dimension D1, and the first dimension D1 is 1 mm to 4 mm. For example, the first dimension D1 may be 1 millimeter, 1.5 millimeters, 1.9 millimeters, 2 millimeters, 3 millimeters, 4 millimeters, and the like. In this way, the aperture of the pinhole 123a may be set in cooperation with the first lens 121 and the second lens 122, so that the influence of stray light (for example, light generated by the display unit 110) is reduced to obtain a pattern of a desired resolution.

In some embodiments, please continue to refer to fig. 5, the touch module 130 includes a cover 131 and a touch layer 132 disposed on a side of the cover 131 facing the optical component 120, and the projection layer 140 is disposed on a side of the touch layer 132 facing away from the cover 131. That is, along the first direction F1, the projection layer 140, the touch layer 132, and the cover plate 131 are sequentially disposed. Optionally, the touch layer 132 is configured as an indium tin oxide conductive film or a metal mesh layer or other transparent conductive layer. Thus, the touch function can be realized by setting the related structure of the touch module 130.

In some embodiments, the haze of the projection layer 140 is greater than 75%. In this way, the pattern imaged on the projection layer 140 has better image quality, and the projection layer 140 has better shielding property, so that the user can observe through the touch module 130. Alternatively, the projection layer 140 may be made of composite PET (polyethylene glycol terephthalate, polyethylene terephthalate) or PET coated with a film layer. The material may be selected according to the desired fog and imaging quality, and the embodiment of the present application is not particularly limited.

In some embodiments, referring to fig. 5, the touch input device 100 further includes a mounting member 150. The mount 150 has a receiving chamber 151 extending in a first direction F1, and first and second openings 152 and 153 oppositely disposed in the first direction F1. The first opening 152 and the second opening 153 communicate with the receiving chamber 151, respectively. Wherein, the end of the mounting member 150 provided with the first opening 152 is mounted on the display side of the display unit 110, the end of the mounting member 150 provided with the second opening 153 is mounted with the touch module 130, and the optical assembly 120 is mounted in the accommodating cavity 151.

Alternatively, the mounting member 150 may be provided in a cylindrical structure to mount various components within the touch input device 100. The material of the mounting member 150 may be plastic, metal or wood, and may be set according to practical use, which is not particularly limited in the embodiment of the present application. Further, the mount 150 is configured as a non-light transmissive member. Alternatively, the mount 150 may be set to black in color. As such, diffuse reflection may occur inside the surface mount 150 to interfere with the imaging process of the optical assembly 120.

In some embodiments, the optical assembly 120 may be mounted within the receiving cavity 151 of the mount 150 by a snap fit or adhesive. Taking fig. 5 as an example, the optical assembly 120 is mounted in the accommodating cavity 151 of the mounting member 150 by means of a clamping manner. The setting may be performed according to actual use conditions, and this is not particularly limited in the embodiment of the present application.

FIG. 6 shows a schematic diagram of the structure at N in FIG. 5; for ease of illustration, only matters relevant to the embodiments of the present application are shown.

In some embodiments, referring to fig. 6 in combination with fig. 5, a step 154 is further provided at the end of the mounting member 150 having the second opening 153. The touch module 130 and the projection layer 140 can be mounted on the mounting member 150 by the step portion 154. Since the projection layer 140 and the touch layer 132 have a certain thickness, the touch module 130 and the projection layer 140 are conveniently mounted.

In some embodiments, referring to fig. 5, the touch input device 100 further includes an elastic member 160. The mounting member 150 is connected to the display unit 110 by means of an elastic member 160. Optionally, the elastic member 160 is made of silica gel. Therefore, when the user performs touch operation, the user can also experience the touch feeling of pressing, and the use experience of the user is further improved.

In some embodiments, referring to fig. 5, the dimension of the mounting member 150 along the first direction F1 is a second dimension D2, and the second dimension D2 is 5 mm to 25 mm. In other embodiments, referring to fig. 5, the dimension of the mounting member 150 along the second direction F2 is a third dimension D3, the third dimension D3 is 3 mm to 10 mm, and the second direction F2 and the first direction F1 are perpendicular to each other. Alternatively, when the mounting member 150 is a cylindrical structure, the second dimension D2 is a height dimension, and the third dimension D3 is an outer diameter dimension.

By defining the second dimension D2, it is thereby possible to avoid not only the occupation of space due to an excessively large size but also the difficulty of optical imaging due to an excessively small size. By defining the third dimension D3, not only the occupation of space due to an excessively large size but also the difficulty of the pressing operation due to an excessively small size can be avoided.
