[0029] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0030] Exemplary embodiments are provided so that the present invention will be exhaustive and will more fully convey the scope to those skilled in the art. Many specific details such as examples of specific components, devices and methods are described to provide a thorough understanding of various embodiments of the present invention. It will be clear to those skilled in the art that specific details need not be employed, and exemplary embodiments may be implemented in many different forms and should not be construed as limiting the scope of the present invention. In some exemplary embodiments, well-known processes, well-known device structures and well-known technologies are not described in detail.

[0031] First, refer to Figures 1 to 3 A touch control device according to a comparative example is described. Figure 1 As shown, the touch device 1 may include a cover 10 and a housing 20 connected to the cover 10. Specifically, the outer peripheral surface of the cover 10 may be formed with an external thread, and the inner peripheral surface of the housing 20 may be formed with an internal thread that matches the external thread, so that the cover 10 may be threadedly connected to the housing 20. The cover 10 may be provided with a touch cover plate 12, and as shown in FIG. Figure 2As specifically shown in the figure, a touch circuit assembly 24 and a touch panel 22 may be accommodated in the housing 20. The touch panel 22 and the touch circuit assembly 24 may be disposed below the touch cover 12. The touch panel 22 and the touch circuit assembly 24 may be configured to generate corresponding control signals according to user instructions input from the touch cover 12. Specifically, the touch cover 12 may be transparent so that the user can clearly observe the touch buttons on the touch panel 22 through the touch cover 12. When the user touches the corresponding touch button position on the touch cover 12 with a finger to input an instruction, the touch panel 22 detects the user's touch position, and then the touch circuit assembly 24 generates corresponding control signals according to the position information detected from the touch panel 22, so that the corresponding control operation can be implemented when the user touches the corresponding button through the touch cover.

[0032] In order to enable the touch device to sensitively respond to the user's touch operation, such as Figure 2 As shown, the touch cover plate 12, the touch panel 22 and the touch circuit assembly 24 can be in close contact with each other. Alternatively, the touch panel 22 can be slightly sunken into the touch cover plate 12 (or the touch panel 22 and the touch cover plate 12 are interference fit). In order to achieve such close contact, as shown in FIG. Figure 2 As shown, a spring 26 may be provided on the side (i.e., the lower side) of the touch circuit assembly 24 opposite to the touch panel 22. The spring 26 may apply elastic force to the touch circuit assembly 24 and the touch panel 22 in a direction toward the touch cover plate 12 to push the touch circuit assembly 24 and the touch panel 22 upward to be in close contact with the touch cover plate 12. The spring 26 may be provided in the groove 25 of the support portion 23.

[0033] However, in the process of threading the cover 10 to the housing 20, the touch cover 12 will rotate on the surface of the touch panel 22 relative to the touch panel 22. Since the touch cover 12 is in close contact with the touch panel 22 under the action of the spring 26, the touch cover 12 is easily scratched by the touch panel 22. Figure 3 The gray area in the figure shows the scratched area of ​​the touch cover plate 12, which corresponds to the area of ​​the entire touch panel 22. Such a scratched touch cover plate 12 not only seriously affects the appearance of the touch device, but also may cause the user to be unable to clearly observe the touch button through the touch cover plate 12, affecting the user's correct operation, which greatly damages the user's experience.

[0034] In order to overcome the above problems, the inventor of the present application proposes an improved touch control device. Figures 4 to 7 A touch control device according to an exemplary embodiment of the present application is described in detail.

[0035] Figure 4 1A according to an exemplary embodiment of the present application is shown. Figure 5 FIG. 1 shows a partial enlarged view of the touch control device 1A. Figure 5 As clearly shown in FIG. 1 , a support member 28 may be disposed between the touch panel 22 and the touch circuit assembly 24 of the touch device 1A, and the area of ​​the support member 28 may be smaller than the area of ​​the touch panel 22. Specifically, the touch panel 22 may include a first area 222 and a second area 224, the first area corresponding to the area where the support member 28 is disposed and the second area corresponding to the area of ​​the touch panel 22 other than the first area. Figure 5 , the second area 224 of the touch panel 22 contacts the touch circuit assembly 24, and the first area 222 of the touch panel 22 is separated from the touch circuit assembly 24 by the support member 28, so that the first area 222 can protrude upward relative to the second area 224. In this case, when the spring 26 pushes the touch panel 22 upward, the first area 222 of the touch panel 22 contacts the touch cover plate 12, and at this time, there is a gap between the second area 224 and the touch cover plate 12 without contact, and the gap corresponds to the thickness of the support member 28. Exemplarily, the thickness of the support member 28 can be less than 1 mm, for example, 0.13 mm.

[0036] In this way, on the one hand, the thickness of the support member 28 is small, so the operational sensitivity of the touch device can still be ensured. On the other hand, since the touch panel contacts the touch cover plate 12 only in the first area 222 rather than the entire touch panel, when the cover 10 is threadedly connected to the housing 20, the area of ​​the touch cover plate 12 that is scratched can be reduced, thereby improving the appearance of the touch device and enhancing the user experience. Moreover, the touch device according to the exemplary embodiment of the present application can achieve the above effect by simply adding a support member between the touch cover plate 12 and the touch circuit assembly 24. This design is very easy to implement, simple in structure and low in cost.

[0037] Reference Figure 6 and Figure 7 Preferably, the support member 28 can be set as a ring member along the outer circumference of the touch panel 22. Figure 7 The gray area shown in represents the scratched area of ​​the touch cover plate 12 in the touch device 1A according to the exemplary embodiment of the present application, and the scratched area corresponds to the first area 222 of the touch panel 22 (i.e., the area where the support member 28 is provided). Since the support member 28 is arranged at the periphery of the touch panel 22, i.e., at the corner where the touch panel 22 and the housing 10 intersect, even if the touch cover plate 12 is slightly scratched at the corner portion, it will not affect the user's manipulation of the touch button of the touch panel, and the scratches at the corner portion are not easily noticed by the user, which further improves the user experience. Exemplarily, the support member 28 can be made of materials such as polyethylene terephthalate (PET), polycarbonate (PC) or adhesive.

[0038] Preferably, the hardness of the material of the touch panel 22 can be less than the hardness of the material of the touch cover 12. For example, the touch panel can be made of polyurethane (TPU). The softer touch panel is not easy to scratch the touch cover, thereby further preventing the touch cover from being scratched. In addition, the touch cover 12 can be hardened, for example, the surface of the touch cover facing the touch panel is UV hardened or additives such as glass fiber fillers or carbon crystal modified materials are added to the raw materials of the touch cover to increase the hardness.

[0039] Preferably, a protective film may be attached to the surface of the touch cover plate 12 facing the touch panel 22, and the protective film may have high wear resistance to prevent the touch cover plate from being scratched by the touch panel 22. And preferably, the surface of the touch panel facing the touch cover plate may be coated with a transparent lubricant, such as a colorless transparent silicone oil-based lubricant, to reduce scratches and wear during the assembly process.

[0040] Preferably, the touch control device of the present invention may be included in a transmitter with a capacitive touch control function. Of course, those skilled in the art should understand that the present invention is not limited thereto, and the touch control device of the present invention may also be applied to various other electronic devices with a touch control function.

[0041] It should also be understood that the present invention is not limited to the specific embodiments described and shown in detail herein, and that various changes may be made to the exemplary embodiments by those skilled in the art without departing from the scope defined by the claims.
