Description

Technical Field

[0001] The utility model belongs to the technical field of pressure-sensitive key switches, and particularly relates to a pressure-sensitive switch and a main body using the pressure-sensitive switch. Background Art

[0002] In electronic products such as smart towel racks, electronic musical instruments, electric shavers, smart home appliances, and smart access control, the switch buttons used include traditional physical buttons and touch buttons.

[0003] Traditional physical buttons usually require a more complex structure to be waterproof, resulting in a poor overall aesthetics of the switch panel. When there are multiple touch buttons, it is difficult to form an integrated structure on the metal panel, and the waterproof and oil-proof effects are poor, and the temperature and humidity are poor during use.

[0004] The pressure-sensitive button triggers the switch through a pressure sensor. When used on a metal switch panel, it has excellent waterproof, oil-proof, anti-mistouch, simple and beautiful effects. It is very suitable for electronic products such as smart towel racks, electronic musical instruments, electric shavers, smart home appliances, smart access control, etc. Therefore, a pressure-sensitive switch is urgently needed in the prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a pressure-sensitive switch, which has excellent waterproof, oil-proof, anti-accidental-touch, simple and beautiful effects, and is very suitable for electronic products such as smart towel racks, electronic musical instruments, electric shavers, smart home appliances, and smart access control.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The utility model provides a pressure-sensitive switch, comprising: a switch panel, a plurality of pressure-sensitive key modules, the switch panel comprising a plurality of key panels, the plurality of key panels being connected to form an integrated structure, the plurality of pressure-sensitive key modules being arranged one-to-one below the plurality of key panels; the pressure-sensitive key modules comprising a PCB mainboard and a pressure sensor, the PCB mainboard being arranged below the key panel, the pressure sensor being attached to and connected to the PCB mainboard, and the PCB mainboard or the pressure sensor being connected to the key panel.

[0008] In the present application, when the pressure sensor is directly connected to the keypad, pressing the keypad can directly trigger the pressure sensor body to undergo micro-deformation, the pressure sensor body senses its own deformation, and processes it through the pressure sensor chip to trigger the pressure switch; when the pressure sensor is connected to the keypad through the PCB motherboard, the pressure sensor body is triggered to undergo micro-deformation through the PCB motherboard, the pressure sensor body senses its own deformation, and processes it through the pressure sensor chip to trigger the pressure switch. Compared to traditional physical buttons and touch buttons, when the present pressure switch is provided with multiple keypads, its switch panel can be provided as an integrated structure, which has excellent effects such as waterproof, oil-proof, anti-mistouch, simple and beautiful.

[0009] Furthermore, a support column is provided between adjacent key panels, and the support column is connected to the key panels on both sides. In the present application, the upper end of the support column is connected to the key panels on both sides, and the lower end is fixed to the housing or other bottom support of the pressure-sensitive switch, so that both ends of the support column are fixed to achieve the supporting function; the support column can separate the adjacent key panels, and when one of the key panels is pressed, due to the support of the support column, the adjacent key panels will not be slightly deformed, thereby achieving the effect of preventing accidental touches and improving the sensitivity of the pressure-sensitive switch.

[0010] Furthermore, the bottom surface of the key panel is hollowed out at the position corresponding to the pressure-sensitive key module to form a slot, and the pressure-sensitive key module is arranged in the slot. The thickness of the key panel at the slot is thinner than the thickness of the surrounding key panels, which is more prone to deformation, making the pressure-sensitive key module easier to trigger.

[0011] Furthermore, the PCB main board and the key board are fixed by glue. The glue fixation enables direct contact between the PCB main board and the key board. When the user presses the key board, the pressing force can be directly transmitted to the PCB main board through the key board, causing the PCB board to undergo micro-deformation. After the pressure sensor senses the deformation pressure of the PCB main board, it measures the pressure through its own deformation and triggers the pressure switch.

[0012] Furthermore, a conductive force column is provided between the keypad and the PCB mainboard, one end of the conductive force column is connected to the bottom surface of the keypad, and the other end is fixedly connected to the PCB mainboard. When the keypad and the PCB mainboard are not in direct contact, a conductive force column is provided between the two, and the PCB mainboard is fixed to the conductive force column to ensure the fixation of the PCB mainboard. The conductive force column can transmit the pressing force of the keypad to the PCB mainboard, causing the PCB mainboard to undergo micro-deformation. The pressure sensor senses the micro-deformation and triggers the pressure switch.

[0013] Furthermore, a hole is dug on the PCB main board to form a deformation groove, and the pressure sensor is arranged on the side of the deformation groove. The deformation groove can make the PCB main board deform better, thereby improving the pressure sensor.

[0014] The present application also provides a main body to which the above-mentioned pressure-sensitive switch is applied, wherein a mounting position is provided on the main body, and the pressure-sensitive switch is mounted on the mounting position.

[0015] Furthermore, the main body includes one of a smart towel rack, an electronic musical instrument, an electric shaver, a smart home appliance, and a smart access control system.

[0016] Compared with the prior art, the beneficial effects of the utility model are: compared with traditional physical buttons and touch buttons, when the pressure-sensitive switch is provided with multiple key panels, its switch panel can be set to an integrated structure, which has excellent waterproof, oil-proof, anti-mistouch, simple and beautiful effects, and is very suitable for electronic products such as smart towel racks, electronic musical instruments, electric shavers, smart home appliances, and smart access control; at the same time, supporting columns are provided between adjacent key panels, which can separate adjacent key panels. When one of the key panels is pressed, due to the support of the supporting columns, the adjacent key panels will not be slightly deformed, thereby achieving the effect of preventing mistouch and improving the sensitivity of the pressure-sensitive switch.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] To achieve the above purpose, the technical solution of the utility model is as follows:

[0027] See also Figure 1-8 As shown, see Figure 1-2 The present embodiment provides a pressure-sensitive switch 100, comprising: a switch panel 1, and a plurality of pressure-sensitive key modules 2. The switch panel 1 comprises a plurality of key panels 11, and the plurality of key panels 11 are connected to form an integrated structure. The plurality of pressure-sensitive key modules 2 are arranged one-to-one below the plurality of key panels 11; the pressure-sensitive key modules 2 comprise a PCB mainboard 21 and a pressure sensor 22. The PCB mainboard 21 is arranged below the key panel 11, and the pressure sensor 22 is attached to and connected to the PCB mainboard 21, and the PCB mainboard 21 or the pressure sensor 22 is connected to the key panel 11.

[0028] In this embodiment, compared with traditional physical buttons and touch buttons, when the pressure-sensitive switch is provided with multiple buttons, its switch panel 1 can be provided as an integrated structure, which has excellent effects such as waterproof, oil-proof, anti-mistouch, simple and beautiful.

[0029] Furthermore, a support column 3 is provided between adjacent key panels 11, and the support column 3 is connected to the key panels 11 on both sides. In this embodiment, the upper end of the support column 3 is connected to the key panels 11 on both sides, and the lower end is fixed to the housing 5 of the pressure-sensitive switch, so that both ends of the support column 3 are fixed to achieve a supporting effect; the support column 3 can separate the adjacent key panels 11, and when one of the key panels 11 is pressed, due to the support of the support column 3, the adjacent key panels 11 will not be slightly deformed, thereby achieving an effect of preventing accidental touches, and improving the sensitivity of the pressure-sensitive switch.

[0030] Further, see Figure 1 The PCB main board 21 and the key board 11 are fixed by glue. The PCB main board 21 and the key board 11 are directly in contact with each other by glue. When the user presses the key board 11, the pressing force can be directly transmitted to the PCB main board 21 through the key board 11, causing the PCB board to deform slightly. After the pressure sensor 22 senses the deformation pressure of the PCB main board 21, it measures the pressure through its own deformation and triggers the pressure switch.

[0031] Further, see Figure 2 A conductive force column 4 is provided between the key panel 11 and the PCB main board 21, one end of the conductive force column 4 is connected to the bottom surface of the key panel 11, and the other end is fixedly connected to the PCB main board 21. When the key panel 11 and the PCB main board 21 are not in direct contact, a conductive force column 4 is provided between the two, and the PCB main board 21 is fixed to the conductive force column 4 to ensure the fixation of the PCB main board 21. The conductive force column 4 can transmit the pressing force of the key panel 11 to the PCB main board 21, causing the PCB main board 21 to undergo micro-deformation, and the pressure sensor 22 senses the micro-deformation to trigger the pressure switch.

[0032] Further, see Figure 1-2 The bottom surface of the key panel 11 is hollowed out at the position corresponding to the pressure-sensitive key module 2 to form a groove 6, and the pressure-sensitive key module 2 is arranged in the groove 6. The thickness of the key panel 11 at the groove 6 is less than the thickness of the surrounding key panels 11, and it is more prone to deformation, making the pressure-sensitive key module 2 easier to trigger.

[0033] See also Figure 3-7 In this embodiment, the pressure-sensitive key module 2 can be implemented in a variety of ways:

[0034] like Figure 3 In this implementation, the pressure sensor 22 of the pressure-sensitive button module 2 is directly arranged below the PCB main board 21, and the PCB main board 21 is connected to the button board 11. When pressed, the PCB main board 21 triggers the pressure sensor 22 body to undergo a micro-deformation. The pressure sensor 22 body senses its own deformation, which is processed by the chip of the pressure sensor 22 to trigger the pressure switch.

[0035] like Figure 4-6 In these implementations, a hole is dug on the PCB main board 21 to form a deformation groove 23, and the pressure sensor 22 is arranged on the side of the deformation groove 23. The shape, position and arrangement of the deformation groove 23 are diversified, which can make the PCB main board 21 deform better and improve the pressure sensor 22.

[0036] like Figure 7 In this implementation, the pressure sensor 22 of the pressure-sensitive button module 2 is arranged above the PCB main board 21, and the pressure sensor 22 is directly connected to the key board 11 to form a direct-pressure button structure. By pressing the key board 11, the pressure sensor 22 body can be directly triggered to undergo micro-deformation. The pressure sensor 22 body senses its own deformation, which is processed by the chip of the pressure sensor 22 to trigger the pressure switch.

[0037] See also Figure 8This embodiment further provides a main body 200 to which the pressure sensing switch 100 is applied. A mounting position 300 is provided on the main body 200 , and the pressure sensing switch 100 is mounted on the mounting position 300 .

[0038] In this embodiment, the main body 200 can be one of a smart towel rack, an electronic musical instrument, an electric shaver, a smart home appliance, and a smart access control.

[0039] Compared with the prior art, the beneficial effects of the utility model are: compared with traditional physical buttons and touch buttons, when the pressure-sensitive switch is provided with multiple key panels 11, its switch panel 1 can be set as an integrated structure, which has excellent waterproof, oil-proof, anti-mistouch, simple and beautiful effects, and is very suitable for electronic products such as smart towel racks, electronic musical instruments, electric shavers, smart home appliances, and smart access control; at the same time, supporting columns 3 are provided between adjacent key panels 11, which can separate the adjacent key panels 11. When one of the key panels 11 is pressed, due to the support of the supporting columns 3, the adjacent key panels 11 will not be slightly deformed, thereby achieving the effect of preventing mistouch, and can improve the sensitivity of the pressure-sensitive switch.
