Description

Technical Field

[0001] This utility model relates to the field of touch switch technology, and specifically to a touch switch assembly. Background Technology

[0002] Touch switches are widely used in electrical control systems of modern homes and various places. Touch switches mainly work based on principles such as capacitive sensing and resistive sensing. Capacitive touch switches trigger the circuit by detecting the change in capacitance caused by human touch, and have the characteristics of high sensitivity and fast response speed. Resistive touch switches rely on the change in resistance value when touched to realize circuit conduction.

[0003] However, traditional touch switches often only control a single position. When multiple touch switches are installed on a control panel, due to their relatively dense positions and the lack of effective backlighting, users may accidentally touch the switch because they cannot see the position clearly in dimly lit environments. Utility Model Content

[0004] This invention provides a touch switch assembly that can transmit light through a transparent plate and a surrounding panel, providing touch guidance for users in the dark.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figures 1 to 8This utility model provides a switch assembly for use in dark environments. The switch assembly's structure is improved to provide backlight indication. Specifically, taking the use of the switch assembly in a dark environment as an example, a preferred embodiment of this invention uses a touch switch assembly capable of providing backlight indication in dark environments.

[0031] Please see Figures 1 to 8 This utility model provides a technical solution: a touch switch assembly, which is applied to scenarios where touch switches are used in dark environments.

[0032] A touch switch assembly includes a protective mechanism 2, a backlight mechanism 6, and a touch mechanism 9, wherein:

[0033] The protective mechanism 2 includes a protective shell 201 and multiple positioning grooves 202. The protective shell 201 is detachably connected to the outer wall of the fixed base 101, and the multiple positioning grooves 202 are respectively opened on the outer wall of the protective shell 201.

[0034] The backlight mechanism 6 includes a transparent plate 601, an LED light 604, and a surrounding plate 602. The transparent plate 601 is detachably connected to the inner wall of the protective shell 201. Multiple surrounding plates 602 are fixedly installed on the outer wall of the transparent plate 601 and are inserted into the inner wall of multiple positioning grooves 202. The LED light 604 is fixedly installed in the middle of the outer surface of the transparent plate 601.

[0035] The touch mechanism 9 is located on the inner wall of the enclosure 602.

[0036] In this embodiment, the protective shell 201 is detachably connected to the outer wall of the fixed base 101, mainly serving to protect the internal components and prevent external factors such as dust and moisture from damaging the internal backlight mechanism 6 and touch mechanism 9. This extends the service life of the components and improves their reliability in different environments. Multiple positioning slots 202 are respectively formed on the outer wall of the protective shell 201, cooperating with the enclosure 602 to position and fix the enclosure 602, and also to guide the light distribution. The effect is to ensure the accuracy of the enclosure 602 installation and to ensure that the light from the backlight mechanism 6 is evenly distributed around the touch area, providing better illumination for operation in dark environments. Clear indication: The transparent plate 601 is detachably connected to the inner wall of the protective shell 201. As the main component for light transmission, it can evenly transmit the light emitted by the LED light 604 to the enclosure 602 through the transparent plate 601, so that the light can be effectively distributed around the touch area, providing clear backlight indication for operation in dark environments. The enclosure 602 is fixedly installed on the outer wall of the transparent plate 601 and is inserted into the positioning groove 202. It not only serves to fix the touch mechanism 9, but also evenly distributes the light transmitted from the transparent plate 601 around the touch area, clearly indicating the touch position in dark environments, avoiding accidental touches, and providing installation support for the touch mechanism 9.

[0037] When light enters the transparent plate 601, it undergoes total internal reflection within the transparent plate 601, thus propagating continuously inside the transparent plate 601 until it reaches the surrounding plate 602, where the surrounding plate 602 transmits the light from the transparent plate 601.

[0038] In the above embodiment, as a preferred solution, the fixing mechanism 1 includes a fixing seat 101, a limiting frame 102, and fixing bolts 103. The outer surface of the fixing seat 101 and the outer surface of the limiting frame 102 are fixedly connected. The fixing bolts 103 are threaded through both sides of the outer surface of the fixing seat 101. The fixing seat 101 serves as the basic component for connecting the entire touch switch assembly to the wall, providing a stable support platform for the subsequent installation of other components, ensuring that the entire assembly can be firmly fixed to the wall and will not loosen due to vibration or external force during daily use. The limiting frame 102 is fixedly connected to the fixing seat 101 to limit the installation position of the protective mechanism 2, ensuring the accuracy and stability of the installation of the protective mechanism 2, so that the protective mechanism 2 can be accurately installed in the designated position, avoiding deviation, thereby ensuring the normal operation and neat appearance of the entire assembly. The fixing bolts 103 are threaded through both sides of the outer surface of the fixing seat 101. By tightening the fixing bolts 103, the fixing seat 101 is tightly fixed to the wall, providing a fastening force, so that the entire touch switch assembly is stably installed on the wall, ensuring safety during use.

[0039] In the above embodiments, as a preferred option, the protective mechanism 2 further includes a sealing gasket 203, which is fixedly connected to the lower part of the outer surface of the protective shell 201. The sealing gasket 203 is fixedly connected to the lower part of the outer surface of the protective shell 201 to enhance the sealing between the protective shell 201 and the wall, further prevent dust and moisture from entering the internal components, improve the protective performance of the components, and better protect the internal electronic components.

[0040] In the above embodiment, as a preferred option, limiting mechanisms 3 are fixedly installed on both sides of the outer surface of the protective shell 201. The limiting mechanism 3 includes a limiting seat 301, two guide holes 302, two main positioning posts 303, two auxiliary positioning posts 304, and four tension springs 305. The two guide holes 302 are respectively opened on both sides of the top of the limiting seat 301. The two main positioning posts 303 are slidably connected to the inner walls of the two guide holes 302. The two main positioning posts 303 are respectively connected to the outer walls of one end of the two auxiliary positioning posts 304 via rotating shafts. The other ends of the two auxiliary positioning posts 304 are fixedly connected to the outer wall of the protective shell 201. One end of each of the four tension springs 305 is fixedly connected to the bottom of the two main positioning posts 303, and the other ends of each of the four tension springs 305 are fixedly connected to the inner bottom walls of the two guide holes 302. The limiting seat 301, as the main support component of the limiting mechanism 3, is fixed on both sides of the outer surface of the protective shell 201, providing additional limiting for other functions. The component provides an installation base. The guide hole 302 is used to guide the movement direction of the main positioning post 303, ensuring the stability and accuracy of the movement of the main positioning post 303. One end of the auxiliary positioning post 304 is connected to the main positioning post 303 via a rotating shaft, and the other end is fixedly connected to the outer wall of the protective shell 201. When the limit seat 301 is pulled down, the connection between the main positioning post 303 and the auxiliary positioning post 304 can be pulled out from the guide hole 302. Then, by means of the rotatability between the main positioning post 303 and the auxiliary positioning post 304, the limit seat 301 can be rotated outward, making it easier to open the protective shell 201 directly upward. The tension spring 305 uses its own elastic force to keep the main positioning post 303 in a certain position. After the main positioning post 303 and the auxiliary positioning post 304 are reset, they are pulled into the guide hole 302, thereby ensuring the connection stability between the limit seat 301 and the protective shell 201 and ensuring sealing.

[0041] In the above embodiment, as a preferred solution, the top and bottom of the limiting frame 102 are provided with fixing grooves 5, and the inner top wall of the protective shell 201 and the inner bottom wall of the limiting seat 301 are fixedly connected with fixing blocks 4. The outer surface of the fixing blocks 4 is inserted into the inner wall of the fixing grooves 5. The fixing blocks 4 are fixed to the inner top wall of the protective shell 201 and the inner bottom wall of the limiting seat 301, and cooperate with the fixing grooves 5 on the limiting frame 102 to further enhance the stability of the installation of the protective shell 201, prevent the protective shell 201 from shaking or displacing during use, improve the overall installation firmness of the protective mechanism 2, and ensure the safety of the internal components.

[0042] In the above embodiments, as a preferred option, the backlight mechanism 6 further includes wire holes 603. Multiple wire holes 603 are respectively opened on the outer surface of the transparent plate 601 and located on the inner wall of the surrounding plate 602. The wire holes 603 are opened on the outer surface of the transparent plate 601 and located on the inner wall of the surrounding plate 602 for the wires 904 to pass through, so as to realize the connection between the circuit board 901 and the external power supply or other devices. The effect is to make the circuit layout more reasonable and ensure the stability and safety of the circuit connection. The LED light 604 is fixedly installed in the middle of the outer surface of the transparent plate 601, serving as the light source of the entire backlight mechanism 6. It emits light and conducts it out through the transparent plate 601 and the surrounding plate 602. The effect is to provide necessary lighting for touch operation in dark environments and improve the accuracy and convenience of operation.

[0043] In the above embodiment, as a preferred solution, positioning holes 7 are provided at the top and bottom of the outer surface of the transparent plate 601, and positioning shafts 8 are fixedly connected at the top and bottom of the outer wall of the limiting frame 102. The inner wall of the positioning hole 7 is engaged with the outer surface of the positioning shaft 8. The positioning holes 7 are provided at the top and bottom of the outer surface of the transparent plate 601 and cooperate with the positioning shafts 8 on the outer wall of the limiting frame 102 to accurately install the transparent plate 601, ensuring the accuracy of the installation position of the transparent plate 601, thereby ensuring the effect of light transmission and distribution. The effect is that the transparent plate 601 can be accurately installed, improving the working efficiency of the backlight mechanism 6.

[0044] In the above embodiments, as a preferred embodiment, the touch mechanism 9 includes a circuit board 901, a first contact 902, a second contact 903, and a wire 904. The circuit board 901 is detachably connected to the inner wall of the enclosure 602. The first contact 902 and the second contact 903 are respectively fixedly installed above and below the outer surface of the circuit board 901. One end of the wire 904 is electrically connected to the bottom of the circuit board 901, and the outer surface of the wire 904 is inserted into the inner wall of the wire hole 603. As the core component of the touch mechanism 9, the circuit board 901 integrates various electronic components for controlling the conduction and disconnection of the circuit and realizing the signal processing of touch operation. The circuit board 901 is configured to transmit signals and enable touch control of electrical devices. The first contact 902 and the second contact 903 are fixedly installed above and below the outer surface of the circuit board 901, respectively. They are used to detect signal changes generated when a human touches the device, such as changes in capacitance or resistance, thereby triggering the circuit and realizing the signal acquisition for touch operation. This provides a basis for subsequent circuit control. One end of the wire 904 is electrically connected to the bottom of the circuit board 901, and the outer surface is inserted into the inner wall of the wire hole 603. This is used to transmit electrical signals and power, connecting the circuit board 901 to external devices or power sources. The effect is to ensure the continuity of the circuit and enable the touch mechanism 9 to work normally.

[0045] In the above embodiments, as a preferred solution, a protective plate 10 is fixedly connected to the outer surface of the protective mechanism 2. The protective plate 10 is fixedly connected to the outer surface of the protective mechanism 2, which further protects the internal structure, prevents external objects from causing collision damage to the component, improves the durability of the component, and extends the service life of the component.

[0046] In this invention, the working steps of the device are as follows:

[0047] 1. First, use the fixing bolts 103 to install the fixing base 101 in a suitable position, and leave the control wire to be connected in the limit frame 102. Then, the worker can insert the appropriate circuit board 901 into the enclosure 602, and pass the wire 904 through the wire hole 603 to connect it to the control wire reserved at the rear, and ensure that the LED light 604 is connected. After the wiring is completed, the transparent plate 601 can be installed and fixed with the positioning shaft 8 and the positioning hole 7. First, pass the positioning shaft 8 through the positioning hole 7, and then slide the transparent plate 601 down to insert the positioning shaft 8 into the smaller position in the positioning hole 7, thus completing the installation of the transparent plate 601.

[0048] 2. Next, pull down the limiting seat 301 to pull out the main positioning post 303 and the auxiliary positioning post 304 from the guide hole 302. Then, the operator can rotate the limiting seat 301 outward to make it easy for the operator to press the bottom of the protective shell 201 against the limiting frame 102. Then, slide it down to insert the fixing block 4 into the fixing groove 5. Then, pull down the limiting seat 301 and align it with the bottom of the limiting frame 102 so that the fixing block 4 can be inserted into the fixing groove 5. At the same time, the tension spring 305 can tighten the protective shell 201 and the limiting seat 301.

[0049] 3. Then, in a dark environment, turn on the LED light 604. The light is transmitted through the transparent plate 601 to the enclosure 602. Then, through the plug-in structure between the enclosure 602 and the positioning groove 202, the light is evenly distributed around the touch area, so that the user can clearly indicate the touch position. The user touches the first contact 902 or the second contact 903 on the circuit board 901 to trigger the circuit, realize the touch control of the electrical equipment, and complete the corresponding switching operation.

[0050] 4. Finally, if the touch mechanism 9 is damaged, since the enclosure 602 installs and fixes the touch mechanism 9 separately, the touch mechanism 9 can be replaced directly without replacing other components such as the light source, thus reducing replacement and maintenance costs. If more in-depth maintenance of the entire component is required, the limit mechanism 3 can be operated to pull the limit seat 301 down, pull out the connection part of the main positioning post 303 and the secondary positioning post 304 from the guide hole 302, rotate the limit seat 301, open the protective shell 201, and inspect and maintain the internal components.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
