[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-5 As shown, the utility model provides a sliding membrane key, including a structural body, which includes a panel layer 1, a silicone layer 2, a circuit layer 4 and a base layer 5 from top to bottom, the silicone layer 2 is provided with a protrusion 3, the protrusion 3 protrudes upward, the panel layer 1 is provided with a circular hole 15, the protrusion 3 extends out of the panel layer 1 through the circular hole 15, the circuit layer 4 is provided with a connecting seat 8, the connecting seat 8 is fixedly connected to the circuit layer 4, an elastic member 9 is provided on the connecting seat 8, a connecting member 6 is fixedly connected to the upper end of the elastic member 9, the connecting member 6 is provided with a pin 7, a metal ball 13 is provided at the end of the pin 7, the circuit layer 4 is also provided with a groove 10, the two poles of the groove 10 are provided with a first contact point 11 and a second contact point 12, and a metal sheet 14 is fixedly connected to the concave surface of the first contact point 11 and the second contact point 12.

[0022] When in use, the user presses down the protrusion 3, driving the connecting member 6 and the pin 7 to move downward, so that the metal ball 13 on the pin 7 enters the first contact point 11 to connect the circuit. The user slides the protrusion 3, so that the metal ball 13 on the pin 7 slides in the groove 10 and enters the second contact point 12 to connect another circuit, so that the button can control the circuit in another way besides long pressing and continuous tapping, thereby reducing the number of button settings while ensuring the completion of the complete input command, making the panel more streamlined and convenient for users to use.

[0023] In which, the outer edge of the protrusion 3 is provided with a highly ductile ring 16, and the ring 16 is a silicone folding ring. The ring 16 is integrally formed with the silicone layer 2, and the lowest points of the first contact point 11 and the second contact point 12 are lower than the lowest point of the groove 10. The protrusion 3 is a bowl-shaped silicone convex bump, and the protrusion 3 is integrally formed with the silicone layer 2, wherein the diameter of the circular hole 15 is consistent with the maximum diameter of the protrusion 3, and the pins 7 are arranged in a circular circle according to the axis of the connecting member 6 and are arranged between the silicone layer 2 and the circuit layer 4. The pins 7 are 4-pin pins 7, and the pins 7 are curved pins 7. The metal sheet 14 is a bowl-shaped metal sheet, and the surface materials of the metal ball 13 and the metal sheet 14 include at least one of beryllium copper, rhodium and ruthenium, and the width of the groove 10 is consistent with the diameter of the metal ball 13.

[0024] When the embodiment of the present application is in use: by setting a highly ductile ring 16, the key is not easily constrained by the lateral shearing force of the protrusion 3 when sliding, and the sliding is easier and smoother. The metal sheet 14 is set as a bowl-shaped metal sheet to increase the contact area between the metal sheet 14 and the metal ball 13, thereby improving the fault tolerance rate.

[0025] When in use, there will be an obvious sense of ups and downs when the key slides from the first contact point 11 to the second contact point 12, which enhances feedback and is used to prompt the user of the current status of the key. The one-piece bowl-shaped silicone convex bump has a long service life and is durable. The bowl-shaped silicone convex bump is effortless to press. The panel layer 1 is fixedly connected to the silicone layer 2, and the protrusion 3 protrudes through the panel layer 1, which is convenient for the user to press directly. The pins 7 are arranged in a circle according to the axis of the connecting part 6, and the pressing force can be distributed to each pin 7. By setting a curved pin 7, the structure of the pin 7 is changed to increase elasticity. When the key slides, the metal ball 13 is just trapped in the groove 10, making the sliding smoother and preventing the metal ball 13 from getting stuck or sliding out of the groove 10 when sliding.

[0026] Beryllium copper, rhodium and ruthenium not only have excellent wear resistance, but also have excellent electrical conductivity, making them excellent in application scenarios where both conditions need to be met.

[0027] Among them, rhodium is one of the platinum metals. Its coating is wear-resistant, has good conductivity, and has high chemical stability and corrosion resistance. Rhodium is widely used in the electronics industry, especially in components that need to withstand high-frequency signals and wear resistance. Ruthenium is a precious metal with excellent electrical properties, such as high conductivity, corrosion resistance, heat resistance, pressure resistance and wear resistance. It can effectively suppress electromagnetic interference and prevent metal surface corrosion.

[0028] The utility model discloses a novel key, which is provided with another mode of controlling the circuit in addition to long pressing and continuous tapping, so as to reduce the setting quantity of keys while ensuring the completion of complete input instructions, make the panel more streamlined, and be convenient for users to use.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
