Correspondingly, the physical buttons on traditional devices have been replaced by widely used touch screen technology. Although the operation of the touch screen is more convenient and fast than that of physical buttons, it is very inconvenient for special groups with visual impairments.

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present utility model as detailed in the appended claims.
[0030] With the development of computer technology, traditional industrial or commercial devices such as POS machine terminals have been iterated into intelligent terminal devices. Correspondingly, the physical keys on traditional devices have been replaced by the widely used touch screen technology. The touch screen technology is a new type of human-computer interaction input method. Compared with the traditional keyboard and mouse input methods, the touch screen input is more intuitive. With the cooperation of recognition software, the touch screen can also achieve handwritten input.
[0031] However, although the operation of the touch screen is more convenient and faster than that of physical buttons, it is very inconvenient for special groups with visual impairments. There have been many solutions in the market to achieve operation functions by configuring physical buttons on the touch screen. For example, silicone buttons are used on touch screen devices, and TP contacts made of conductive silicone are used to connect the human capacitance to achieve touch sensing, and then the physical button simulation function is realized. However, in these solutions, the human finger needs to directly touch the conductive silicone button entity (or touch the button through a conductor), and the button function can only be realized when the button is pressed down. That is, only the needs of ordinary physical buttons can be met, and the button needs in other special scenarios cannot be satisfied. For example, operators wearing gloves need to use physical button accessories, etc. In these scenarios, even if the physical button accessories touch the touch screen of the smart device, the physical button operation function cannot be realized.
[0032] An embodiment of the present invention provides a button device, which is applicable to a smart POS device. Specifically, as Figure 1 shown, the button device includes a non-conductive component 100 and a conductive silicone component 200. A plurality of key slots are provided on the surface of the non-conductive component 100; on a part of the conductive silicone plane on the upper surface of the conductive silicone component 200, raised silicone buttons having the same size as the plurality of key slots are provided. Raised silicone contacts are provided at positions corresponding to the raised silicone buttons on the lower surface of the conductive silicone component 200. The height of the raised silicone contacts is less than the height of the key slots. The conductive silicone component 200 is assembled and fixed on the surface of the non-conductive component 100 by a fixture to form an integral body, and the raised silicone contacts are located in the key slots on the surface of the non-conductive component 100.
[0033] As Figure 2 and Figure 3 shown, Figure 2 is a schematic structural diagram of the non-conductive silicone component provided by an embodiment of the present application, Figure 3 is a schematic structural diagram of the conductive component provided by an embodiment of the present application, Figure 1 is a schematic structural diagram of the button device provided by an embodiment of the present application.
[0034] The button device is movably installed on the smart POS device. The smart POS device has a capacitive touch screen. The smart POS device can be a POS terminal. When the user normally uses the smart POS device, the button device can be not installed. When the user uses the button device, the user can perform button operations with a human finger or can also perform button operations through an insulating object.
[0035] As Figure 2 shown, a plurality of key slots 101 are provided on the surface of the non-conductive component 100 in the button device;
[0036] Specifically, the key slot 101 is the same size as the protruding silicone button 201 in the conductive silicone component;
[0037] Specifically, the non-conductive component 100 is formed by injecting silicone material heated and melted by an injection molding machine into a mold and then cooling and solidifying;
[0038] Furthermore, the non-conductive component 100 can be insulating silicone;
[0039] Specifically, as Figure 4 shown, the non-conductive component 100 has a receiving space 102 and a first opening 103, and the key device composed of the non-conductive component 100 can be movably installed on the device with a capacitive touch screen.
[0040] Specifically, the key device is formed by assembling the conductive silicone component 200 on the upper surface of the non-conductive component 100 through a fixture and fixing them into one body, and the protruding silicone contact 202 is located in the key slot 101 on the upper surface of the non-conductive component 100;
[0041] Furthermore, the key device is formed by fixing the conductive silicone component 200 and the non-conductive component 100 together with glue.
[0042] As Figure 3 shown, on the partial conductive silicone surface on the upper surface of the conductive silicone component 200 in the key device 100, there are protruding silicone buttons 201 of the same size as the multiple key slots 101. At the position corresponding to the protruding silicone buttons 201 on the lower surface of the conductive silicone component 200, there are protruding silicone contacts 202, and the height of the protruding silicone contacts 202 is less than the height of the key slots 101;
[0043] In this embodiment, the area of the conductive silicone surface needs to be large enough. On a part of the plane, there are protruding silicone buttons 201 of the same size as the multiple key slots. On a part of the plane 203, when the shape of the protruding silicone button changes, it drives the shape of the plane to change, thereby generating a capacitance effect so that its capacitance effect can be sensed by the capacitive touch screen;
[0044] Specifically, the conductive silicone component 200 is formed by injecting silicone material heated and melted by an injection molding machine into a mold and then cooling and solidifying, and silk-screen printing is performed on the surface of the protruding silicone button for easy user identification;
[0045] Specifically, specific buttons in the protruding silicone buttons 201 have protruding symbol structures, enabling blind people to identify them by touch and identify the positions of other buttons through the button arrangement relationship;
[0046] Specifically, as Figure 5As shown, the raised silicone button 201 of the conductive silicone component further includes a keycap 300. The keycap 300 can be made of non-conductive material or conductive material. When the keycap 300 is pressed and deformed, the keycap 300 drives the raised silicone button 201 to make the raised silicone contact 202 contact the capacitive touch screen 501. Silk printing can also be performed on the keycap 300 for easy user identification.
[0047] In this embodiment, the area of the conductive silicone surface is large enough. A part of the plane can be driven by the raised silicone button 201 so that the plane shape changes to generate a capacitance effect. Therefore, even when a non-insulator contacts the raised silicone button 201, the capacitive touch screen 501 can still be induced. Subsequently, the keycap 300 on the raised silicone button 201 can be made of non-conductive material.
[0048] The present invention also provides an intelligent POS device, such as Figure 6 shown, the intelligent POS device includes:
[0049] A touch display device 500, including a capacitive touch screen 501;
[0050] A button device 100, which is the button device 100 provided by the present invention, and the button device 100 is movably installed on the touch display device 500.
[0051] In this embodiment, after the button device 100 is installed on the intelligent POS device, as Figure 7 shown, when the raised silicone button 201 is not pressed, no position in the conductive silicone component 200 contacts the capacitive touch screen 501 in the touch display device 500, and the conductive silicone plane 203 of the conductive silicone component 200 is far from the capacitive touch screen 501 in the intelligent POS device, so that the capacitive touch screen 501 cannot sense the button. As Figure 8 shown, when the raised silicone button 201 in the conductive silicone component 200 is pressed, the raised silicone contact 202 corresponding to the raised silicone button is capacitively coupled with the capacitive touch screen 501 to establish an electric field connection, and the equivalent capacitance formed by the entire conductive silicone plane is connected to the capacitive touch screen 501. The conductive silicone plane of the conductive silicone component 200 contacts the capacitive touch screen 501 in the intelligent POS device at the pressing point, and the capacitive touch screen 501 in the intelligent POS device senses the touch, thereby realizing the physical button function.
[0052] Through the solution provided in this embodiment, the user can operate the touch display device 500 through the button device 100 to implement the physical button function on the intelligent terminal device with a touch screen. Through this solution, it is not necessary to rely on human capacitance, and physical button operations can be achieved even by touching with an insulating object or when the user wears insulating gloves, etc., without affecting the function at all. In addition, the structure of this solution is simple, the cost is low, the button device is made of silica gel and is not easily damaged, and it can be movably installed on the intelligent terminal device to work, which is convenient for disassembly and assembly.
[0053] It should be noted that in this utility model, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or order; the term "plurality" means two or more, unless otherwise clearly defined. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after. Terms such as "installation", "connection", "connection", and "fixation" should all be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0054] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to this utility model.
[0055] The above is only the specific implementation manner of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model can easily think of changes or substitutions, which should all be covered by the protection scope of this utility model. Therefore, equivalent changes made according to the claims of this utility model still fall within the scope covered by this utility model.
