Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive film technology, and in particular to a low-power conductive film suitable for wireless keyboards. Background Technology
[0002] Wireless keyboards, as core devices for human-computer interaction, are widely used in computers, smart terminals, and IoT scenarios. Their core component, the conductive film, is responsible for generating and transmitting keycap trigger signals. With the increasing trend towards miniaturization and thinner designs in wireless devices, the conductive film must simultaneously meet the requirements of low power consumption, high response speed, and long-term reliability within a limited space. Currently, most mainstream conductive films use physical clips or adhesives to fix the keycaps and transmit electrical signals directly through a single conductive layer. This results in problems such as easy loosening of keycap connections and signal attenuation after contact wear, making it difficult to adapt to high-frequency typing and the shock resistance requirements of portable devices. Furthermore, traditional conductive films have higher circuit impedance, leading to increased power consumption, severely limiting the battery life of wireless keyboards and making them incompatible with the low-power specifications of Bluetooth 5.0 and above.
[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Firstly, the keycap connection stability is poor. Traditional keycaps rely on plastic clips or adhesives for fixing, which can easily lead to loosening and detachment due to mechanical fatigue or adhesive aging after prolonged use. This can cause shaking noise during typing and structural damage when the device is dropped. Secondly, the electrical signal transmission efficiency is low. The single conductive layer design lacks signal optimization paths, and insufficient or uneven contact area can easily lead to resistance fluctuations. The trigger signal requires a higher driving voltage to compensate for losses, significantly increasing overall power consumption. Finally, reducing the conductive layer thickness to lower power consumption exacerbates the risk of material fatigue and fracture, while thickening the conductive layer improves durability but increases impedance. The existing structure struggles to balance low power consumption and long lifespan, limiting the performance of wireless keyboards under high-intensity usage scenarios. Utility Model Content

[0038] like Figure 1-6As shown, a keycap 1 is fixedly connected to the outer side of the bottom shell 4, a magnetic block 51 is provided at the bottom of the keycap 1, and a clip 2 is installed on the outer side of the keycap 1.
[0039] It should be explained that the keycap 1 is fixedly connected to the outside of the bottom shell 4. The bottom shell 4 provides a stable mounting position for the keycap 1, allowing the keycap 1 to be positioned stably. A magnetic block 51 is set at the bottom of the keycap 1.

It allows the magnetic block 51 and the keycap 1 to be tightly connected, ensuring that the keycap 1 is stably installed on the keyboard and can perform the input function normally.
[0042] like Figure 1-6 As shown, a transmission layer 58 is fixedly installed on the outside of the connecting column 55, and a magnetic block 51 is installed on one side of the transmission layer 58.

[0048] The principle of using a low-power conductive film suitable for wireless keyboards in this embodiment is as follows:
[0049] First, when the user presses the keycap 1, the magnetic attraction force generated by the magnetic block 51 at the bottom of the keycap 1 helps it to be tightly connected to the internal structure of the keyboard. At the same time, the second ring 56 can further ensure the stable installation of the keycap 1 and ensure that the keycap 1 can perform the input function normally.
[0050] Secondly, during signal transmission, the transmission layer 58 utilizes the conductivity of the carbon powder to carry out the actual transmission of electrical signals, while the conductive layer 57 efficiently guides the current thanks to the excellent conductivity of graphene. The two layers work together to achieve stable and efficient signal transmission. Furthermore, the delivery layer 59 protects the transmission layer 58 while also assisting in signal transmission, ensuring the stability of the signal transmission.
[0051] Finally, the protective shell 3 uses silver paste conductive material, which can not only help to conduct electrical signals, but also provide protection for the internal structure; the bottom shell 4 uses tin oxide fluorine material, which can provide bottom support and protection for the entire structure, so that the entire conductive film structure can play a stable role in the wireless keyboard, while achieving low power consumption operation.
