[0038] Reference Figures 1 to 8 As shown, a touch metal sheet 100 according to an embodiment of the present invention includes: a connecting piece 110, a support piece 130, a sensing piece 120, and a pin 140.

[0039] Reference Figure 1As shown, specifically, the length direction of the connecting piece 110 is set along the vertical direction, the width direction of the connecting piece 110 is set along the horizontal direction, and the thickness direction of the connecting piece 110 is set along the front-back direction. That is, both ends of the connecting piece 110 are set along the vertical direction, the length direction of the support piece 130 is set along the vertical direction, and the support piece 130 is arranged at an angle to the connecting piece 110 and is connected to the circumference or side of the connecting piece 110. The lower end of the support piece 130 is flush with the lower end of the connecting piece 110.

[0040] Reference Figure 1 As shown, specifically, the pin 140 is arranged vertically along its length, meaning the upper end of the pin 140 connects to the lower end of the connecting piece 110, while the lower end of the pin 140 is configured to connect to the circuit board 300. The pin 140 is adaptable to the pin spacing of an automatic insertion machine, allowing the automatic insertion machine to assemble the pin 140 of the touch metal piece 100 with the circuit board 300, thus positioning the touch metal piece 100 with the circuit board 300.

[0041] Reference Figure 1 As shown, the support piece 130 and the connecting piece 110 are arranged at an angle and are connected to the circumference or side of the connecting piece 110. The lower ends of both the support piece 130 and the connecting piece 110 can abut against the circuit board 300. By connecting with the connecting piece 110 and abutting against the circuit board 300, the support piece 130 can effectively support the connecting piece 110 and prevent the connecting piece 110 from tipping over relative to the circuit board 300.

[0042] Reference Figure 1 As shown, the sensing element 120 is connected to the upper edge of the support piece 130 or the connecting piece 110. The sensing element 120 is configured to sense the capacitance change caused by human touch, thereby sending a trigger signal to the circuit board 300 and cooperating with the functional components of the peripheral device to realize the touch sensing function.

[0043] Traditional touch-sensing devices typically use touch springs as their elastic element. Touch springs cannot be automatically inserted by AI and can only be inserted manually. In order to position them, a connector needs to be further processed or soldered onto the touch spring. Moreover, the connector can only be formed at the edge of the spring, which reduces assembly efficiency and increases manufacturing costs.

[0044] Reference Figure 1 As shown, compared to a touch spring, the touch metal sheet 100 provided in this embodiment of the present invention can replace the spring as the elastic element of the touch sensing device, which is suitable for automatic insertion of automatic insertion machines, resulting in higher assembly efficiency and lower manufacturing cost compared to the method of further processing on the spring.

[0045] Reference Figure 1As shown, it can be understood that the upper edge of the sensing sheet 120 is connected to the connecting sheet 110 and arranged at an angle to the connecting sheet 110. Specifically, the sensing sheet 120 and the connecting sheet 110 are arranged at a right angle, which can effectively increase the sensing area of ​​the sensing sheet 120. The touch metal sheet 100 can use air as a conductive medium. By increasing the sensing area of ​​the sensing sheet 120, it can sense the capacitance change caused by human touch, and make the sensing of the sensing sheet 120 more accurate and sensitive.

[0046] Reference Figure 1 As shown, both the sensing sheet 120 and the connecting sheet 110 can be thin sheets. The sensing sheet 120 and the connecting sheet 110 can be integrally bent and formed, thereby improving the connection stability between the sensing sheet 120 and the connecting sheet 110, and making the processing and manufacturing cost of the sensing sheet 120 and the connecting sheet 110 lower.

[0047] It should be understood that in some other embodiments, the sensing sheet 120 is connected to the upper edge of the support sheet 130 and is arranged at an angle to the support sheet 130. Specifically, the sensing sheet 120 is arranged at a right angle to the support sheet 130, which can effectively increase the sensing area of ​​the sensing sheet 120. The touch metal sheet 100 can use air as a conductive medium. By increasing the sensing area of ​​the sensing sheet 120, it can sense the capacitance change caused by human touch, and make the sensing of the sensing sheet 120 more accurate and sensitive.

[0048] Both the sensing sheet 120 and the support sheet 130 can be thin sheets. The sensing sheet 120 and the support sheet 130 can be integrally bent and formed, thereby improving the connection stability of the sensing sheet 120 and the support sheet 130 and making the processing and manufacturing cost of the sensing sheet 120 and the support sheet 130 lower.

[0049] It should be understood that in some other embodiments, the touch metal sheet 100 does not include the sensing sheet 120, and the upper end of the connecting piece 110 can also be used to sense capacitance changes caused by human touch. (Refer to...) Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the sensing sheet 120 is provided with a light-transmitting hole 121 that runs through the top and bottom. The touch metal sheet 100 can be used in conjunction with the indicator light 400. Both the indicator light 400 and the touch metal sheet 100 are connected to the electronic control board. The indicator light 400 is configured to operate according to the capacitance change sensed by the touch metal sheet 100.

[0050] Reference Figure 1 , Figure 4 and Figure 5As shown, the touch metal piece 100 is used adjacent to the indicator light 400. When the sensing piece 120 senses the capacitance change caused by human touch, it can convert the capacitance change into an electrical signal on the circuit board 300. The circuit board 300 can then control the indicator light 400 to light up, thus forming a touch feedback for the light to illuminate. The light-transmitting hole 121 provided on the sensing piece 120 can be positioned opposite to the lamp head of the indicator light 400 to reduce obstruction of the light emitted by the indicator light 400. That is, the light-transmitting hole 121 allows the light emitted by the indicator light 400 to pass through, thereby providing a better light indication function.

[0051] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that the support piece 130 is connected to the side of the connecting piece 110, and the support piece 130 and the connecting piece 110 are arranged at right angles. By the contact between the lower end of the support piece 130 and the lower end of the connecting piece 110 and the circuit board 300, the positioning and connection of the connecting piece 110 and the circuit board 300 can be made more stable, which helps to avoid the problem of the connecting piece 110 tilting or falling over relative to the circuit board 300.

[0052] Reference Figure 1 , Figure 4 and Figure 5 As shown, the support piece 130 is in the shape of a thin sheet. The support piece 130 and the connecting piece 110 are integrally bent and formed, thereby improving the connection stability between the connecting piece 110 and the support piece 130, and making the processing and manufacturing cost of the connecting piece 110 and the support piece 130 lower.

[0053] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that two support plates 130 are provided, and the two support plates 130 are respectively connected to the two sides of the connecting plate 110. The two support plates 130 are parallel to each other and extend in a direction away from each other.

[0054] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, both support plates 130 are arranged at right angles to the connecting plate 110. One support plate 130 extends forward relative to the connecting plate 110, and its lower end abuts against the circuit board 300, effectively supporting the connecting plate 110 and preventing it from tilting forward. The other support plate 130 extends backward relative to the connecting plate 110, and its lower end abuts against the circuit board 300, effectively supporting the connecting plate 110 and preventing it from tilting backward.

[0055] Reference Figure 1 , Figure 4 and Figure 5 As shown, the touch metal piece 100 can be connected to the connecting piece 110 through two support pieces 130, thereby effectively supporting the connecting piece 110. By attaching the lower ends of the two support pieces 130 and the lower ends of the connecting piece 110 to the circuit board 300, the contact area between the touch metal piece 100 and the circuit board 300 can be increased, thereby improving the connection stability between the touch metal piece 100 and the circuit board 300.

[0056] It should be understood that in some other embodiments, the support piece 130 may be connected to the circumferential surface of the connecting piece 110, and the support piece 130 and the connecting piece 110 may be integrally extruded, thereby improving the connection stability between the support piece 130 and the connecting piece 110.

[0057] Reference Figure 7 It should be understood that in some other embodiments, the support piece 130 and the connecting piece 110 are arranged in parallel, with both ends of the support piece 130 arranged in the vertical direction, while the sensing piece 120 is arranged at right angles to the upper ends of the support piece 130 and the connecting piece 110. The upper end of the support piece 130 is connected to the side of the sensing piece 120 away from the connecting piece 110. Specifically, the support piece 130 is connected to the rear end of the sensing piece 120, while the connecting piece 110 is connected to the front end of the sensing piece 120.

[0058] Reference Figure 1 , Figure 5 and Figure 6 As shown, it can be understood that in this embodiment, the pin 140 includes a first pin 141 and a second pin 142 that are parallel to each other. The upper ends of the first pin 141 and the second pin 142 are both connected to the lower end of the connecting piece 110. The first pin 141 and the second pin 142 can cooperate with the insertion holes on the circuit board 300. Under the insertion action of the automatic insertion machine of the peripheral device, the first pin 141 and the second pin 142 can be inserted into the two insertion holes on the circuit board 300 respectively, thereby realizing the insertion of the pin 140 and the circuit board 300, that is, realizing the assembly of the touch metal piece 100 and the circuit board 300. Compared with the manual insertion method, the touch metal piece 100 can be adapted to the automatic insertion of the automatic insertion machine, which can effectively improve the assembly efficiency.

[0059] Reference Figure 1 , Figure 5 and Figure 6 As shown, specifically, the connecting piece 110, the sensing piece 120, the supporting piece 130, and the pin 140 are all made of metal to ensure that the touch metal piece 100 can sense the capacitance change caused by human touch.

[0060] Reference Figure 1 , Figure 5 and Figure 6As shown, the touch metal sheet 100 also includes a conveyor frame 150, which is connected to the lower end of the pin 140. The conveyor frame 150 can be used to connect with the conveyor tape of an automatic insertion machine. By connecting the conveyor tape to the conveyor frame 150 and cooperating with the conveyor tape, multiple touch metal sheets 100 can be conveyed, thereby simplifying the conveying method of the touch metal sheets 100 and improving the conveying efficiency of the touch metal sheets 100.

[0061] Reference Figure 1 , Figure 5 and Figure 6 As shown, the conveying frame 150 can be rectangular, and two adjacent corners of the conveying frame 150 are fixedly connected to the lower ends of the first support 141 and the second support 142, respectively. Before or after the touch metal piece 100 is inserted into the circuit board 300, the conveying frame 150 can be removed by cutting or other means.

[0062] Reference Figure 2 , Figure 3 and Figure 4 As shown in the figure, a touch button provided by this utility model includes a touch metal sheet 100, a circuit board 300 and a cover plate 200 as shown in any of the above embodiments.

[0063] Reference Figure 1 , Figure 3 and Figure 4 As shown, taking the connecting piece 110 arranged vertically along its length as an example, the circuit board 300 is horizontally positioned, and the pins 140 of the touch metal piece 100 can be inserted into the circuit board 300 to achieve positioning and connection between the touch metal piece 100 and the circuit board 300. A cover plate 200 is placed over the touch metal piece 100 and the circuit board 300, and a sensing piece 120 is adjacent to the cover plate 200. Specifically, the sensing piece 120 and the cover plate 200 are spaced apart, using air as the conductive medium. The cover plate 200 is configured to transmit capacitance changes caused by human touch to the sensing piece 120.

[0064] Reference Figure 1 , Figure 3 and Figure 4As shown, the connecting piece 110 can serve as the main body for connecting the sensing piece 120, the support piece 130, and the pin 140. Both ends of the connecting piece 110 are arranged vertically. The upper end of the pin 140 connects to the connecting piece 110. The pin 140 can be adapted to the pin spacing of an automatic insertion machine, allowing the automatic insertion machine to assemble the pin 140 of the touch metal piece 100 with the circuit board 300, thus positioning the touch metal piece 100 with the circuit board 300. The support piece 130 is arranged at an angle to the connecting piece 110 and connects to the circumference or side of the connecting piece 110. The lower ends of both the support piece 130 and the connecting piece 110 can abut against the circuit board 300. The support piece 130 abuts against the circuit board 300 through its connection with the connecting piece 110 and its abutment against the circuit board 300. The connecting piece 110 can be effectively supported to prevent it from tipping over relative to the circuit board 300. The sensing piece 120 is connected to the upper edge of the connecting piece 110 or the supporting piece 130. The cover plate 200 covers the touch metal piece 100 and the circuit board 300. The cover plate 200 is configured to transmit the capacitance change caused by human touch to the sensing piece 120. The sensing piece 120 is configured to sense the capacitance change caused by human touch and convert it into an electrical signal of the circuit board 300. In conjunction with the functional components of the peripheral device, the touch sensing function is realized. The touch button uses the touch metal piece 100 instead of the spring as the elastic element of the touch feedback device, which is suitable for automatic insertion machines, resulting in higher assembly efficiency and lower manufacturing cost compared to the method of reprocessing on the spring.

[0065] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that the touch button also includes an indicator light 400 connected to the circuit board 300, a light-transmitting hole 121 on the sensing sheet 120, a touch metal sheet 100 adjacent to the indicator light 400, the sensing sheet 120 being located above the indicator light 400 and spaced apart from the cover plate 200, and the light-transmitting hole 121 being opposite to the indicator light 400.

[0066] Reference Figure 1 , Figure 4 and Figure 5As shown, the touch metal piece 100 is used adjacent to the indicator light 400. When the sensing piece 120 senses the capacitance change caused by human touch, it can convert the capacitance change into an electrical signal on the circuit board 300. The circuit board 300 can then control the indicator light 400 to light up, thus forming a touch feedback for the light to illuminate. The light-transmitting hole 121 on the sensing piece 120 can be positioned opposite to the lamp head of the indicator light 400 to reduce obstruction of the light emitted by the indicator light 400. Furthermore, the upper end of the sensing piece 120 is spaced apart from the cover plate 200, which can effectively reduce the obstruction of the light emitted by the sensing piece 120 to the light emitted by the indicator light 400. This allows the light emitted by the indicator light 400 to pass through the light-transmitting hole 121 and the gap between the sensing piece 120 and the cover plate 200, thereby providing better light indication.

[0067] Reference Figure 8 As shown, it should be understood that in some other embodiments, the touch metal piece 100 is connected to two or more indicator lights 400. The touch metal piece 100 is disposed between the corresponding two or more indicator lights 400. When the touch metal piece 100 senses the capacitance change caused by human touch, it can convert the capacitance change into an electrical signal of the circuit board 300. The circuit board 300 can control the corresponding two or more indicator lights 400 to light up, thereby forming touch feedback that illuminates two or more indicator lights 400. That is, the touch metal piece 100 can be used in scenarios with two or more indicator lights 400.

[0068] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the internal size of the light-transmitting hole 121 is larger than the external size of the indicator light 400, so that the upper end of the indicator light 400 can be inserted into the light-transmitting hole 121, thereby avoiding the problem of the sensing sheet 120 obstructing the installation height of the indicator light 400. In addition, the larger internal size of the light-transmitting hole 121 helps to reduce the obstruction of the sensing sheet 120 on the optical fiber emitting of the indicator light 400. That is, the light-transmitting hole 121 allows the light emitted by the indicator light 400 to pass through, thereby playing a better light indication role.

[0069] It should be understood that in some other embodiments, the touch button includes a buzzer, and the touch metal sheet 100 is used adjacent to the buzzer. When the sensing sheet 120 senses the capacitance change caused by human touch, it can convert the capacitance change into an electrical signal of the circuit board 300. The circuit board 300 can control the operation of the buzzer, thereby forming a touch feedback that emits a sound after touch.

[0070] It should be understood that in some other embodiments, the touch button includes a vibration motor, and the touch metal sheet 100 is used adjacent to the vibration motor. When the sensing sheet 120 senses the capacitance change caused by human touch, it can convert the capacitance change into an electrical signal of the circuit board 300. The circuit board 300 can control the operation of the vibration motor to form a touch feedback of vibration after touch.

[0071] Reference Figure 1 , Figure 5 and Figure 6 As shown, it can be understood that in this embodiment, a sleeve 220 is connected to one end of the cover plate 200 facing the circuit board 300. The sleeve 220 has a receiving groove 221 with an opening facing the touch metal piece 100. The touch metal piece 100 and the indicator light 400 are both embedded in the receiving groove 221. The end of the sleeve 220 away from the cover plate 200 abuts against the circuit board 300.

[0072] Reference Figure 1 , Figure 5 and Figure 6 As shown, the cover plate 200, through the contact between the sleeve 220 and the circuit board 300, can fix the distance between the cover plate 200 and the circuit board 300, thereby reducing the risk of damage to the components located between the cover plate 200 and the circuit board 300 due to pressure on the cover plate 200. Furthermore, both the touch metal piece 100 and the indicator light 400 are embedded in the receiving groove 221, and the sleeve 220 can circumferentially restrict the light of the indicator light 400, thereby making the light of the indicator light 400 more concentrated and the indicating effect of the indicator light 400 more obvious.

[0073] Reference Figure 1 , Figure 5 and Figure 6 As shown, specifically, the cover plate 200 has a touch sensing area 210 on the surface facing away from the sleeve 220.
