Description

Technical Field

[0001] This application relates to the field of touch screen display technology, and in particular to a touch screen conversion film for electronic screens. Background Technology

[0002] With the development of technology, touchscreen technology is widely used in various electronic devices. However, older equipment is not equipped with touchscreen functionality, and for organizations that need touchscreens, replacing all the old equipment would undoubtedly be a very large office cost.

[0003] To meet the demand for touchscreen upgrades in these older devices, some solutions have emerged on the market, but these primarily involve replacing the entire display module. This approach is not only costly and complex, but also requires customized solutions for different device models, lacking universality. Furthermore, replacing the entire display module results in a waste of resources.

[0004] Therefore, how to add touch screen functionality to older devices in a low-cost, easy-to-operate, and universally applicable way has become an urgent problem to be solved in this field. Utility Model Content

[0005] To improve the convenience of adding touch screen functionality to electronic screens, this application provides a touch screen conversion film for electronic screens.

[0006] The technical solution provided in this application for a touch screen conversion film for electronic screens is as follows:

[0007] A touch screen conversion film for electronic screens includes a transparent touch-sensing layer and a flexible circuit layer located on one side of the touch-sensing layer. A fixing frame is provided between the touch-sensing layer and the flexible circuit layer. A USB interface electrically connected to the flexible circuit layer is provided on the bottom wall of the fixing frame. A connection component for quick installation with the electronic screen is provided on the side wall of the fixing frame facing the electronic screen. The connection component includes flexible magnetic blocks disposed opposite to the fixing frame and the electronic screen, and multiple flexible magnetic blocks are arranged circumferentially along the side wall of the fixing frame facing the electronic screen.

[0008] By adopting the above technical solution, the conversion film can be easily installed on the electronic screen under the magnetic attraction of the soft magnetic block, and data interaction with the electronic device can be achieved through the USB interface, thus realizing the addition of touch screen function. The use of a transparent touch-sensing layer and a flexible circuit layer, combined with a fixed frame design, makes the touch screen conversion film suitable for electronic screens of various sizes and shapes, achieving low-cost and high-efficiency addition of touch screen functionality to older devices.

[0009] Optionally, the fixed frame is further provided with several buffer components on the circumferential side wall facing the electronic screen.

[0010] By adopting the above technical solution, the buffer can be a silicone pad, a micro spring or other elastic material with buffering function. When the touch screen conversion film is attached to the electronic screen, the buffer provides appropriate buffering force, ensuring that the touch screen conversion film and the electronic screen are tightly attached while avoiding damage to the electronic screen due to excessive adhesion.

[0011] Optionally, the connecting assembly further includes clamping members, one of which is provided on each of the two opposite vertical sidewalls of the fixed frame. Each clamping member includes a connecting plate provided on the vertical sidewall of the fixed frame and an L-shaped limiting plate that rotatably engages with the connecting plate. A rotating shaft parallel to the length direction of the connecting plate is provided at the connection between the limiting plate and the connecting plate, and a torsion spring is sleeved on the rotating shaft. When the fixed frame is magnetically installed on the electronic screen, the two oppositely arranged limiting plates clamp and limit the electronic screen between the limiting plate and the fixed frame.

[0012] By adopting the above technical solution, when the user installs the touchscreen conversion film on the electronic screen, they flip the L-shaped limiting plate, and under the elastic action of the torsion spring, the electronic screen is clamped. The clamping component further improves the connection stability between the touchscreen conversion film and the electronic screen.

[0013] Optionally, the fixed frame has insertion slots on the side walls opposite to both sides along the length of the side walls. The cross-section of the insertion slots is wedge-shaped. The connecting plate has an insertion part on the side near the fixed frame. The insertion part and the insertion slot are inserted into each other.

[0014] By adopting the above technical solution, the cooperation between the slot and the connector allows the clamping component to be easily installed and removed on the fixed frame, making it convenient for users to selectively use the clamping component according to actual needs, and also making it convenient to replace the clamping component according to the electronic screen with different signals.

[0015] Optionally, the limiting plate includes a support plate and a clamping plate connected to the side of the support plate away from the connecting plate. The clamping plate is arranged perpendicular to the support plate. Multiple guide rods are distributed along the length of the clamping plate on its side wall facing the support plate. Each guide rod is arranged along the length of the support plate. A limiting groove is formed on the side wall of the support plate corresponding to each guide rod along the length of the guide rod. An end block is provided at the end of each guide rod located in the limiting groove. The end block slides with the corresponding limiting groove. A blocking ring for limiting the end block is coaxially arranged on the side wall of the support plate at the opening of the limiting groove. A spring is sleeved on each guide rod. The spring is located in the limiting groove and abuts against the side wall opposite to the blocking ring and the end block.

[0016] By adopting the above technical solution, the cooperation between the guide rod and the limiting slide groove enables the clamping plate to move within a certain range, and the spring provides clamping force to ensure that the electronic screen is stably clamped, providing appropriate clamping force for electronic screens of different thicknesses and improving the applicability of the clamping component.

[0017] Optionally, a rubber pad is provided on the side wall of the limiting plate facing the electronic screen.

[0018] By adopting the above technical solution, the rubber pad can transform the hard contact between the clamping plate and the electronic screen into a flexible contact, thereby reducing the damage to the electronic screen when the clamping plate clamps the electronic screen and protecting the electronic screen.

[0019] Optionally, the fixed frame and the touch-sensing layer are both made of flexible memory material.

[0020] By adopting the above technical solutions, flexible memory materials enable the conversion film to be applied to curved electronic screens, thereby expanding the applicability of touch screen conversion films.

[0021] Optionally, a strap is provided on one side of the fixing frame, and a hook and loop fastener is provided on the end of the strap away from the fixing frame, and a loop and loop fleece is provided on the end of the strap away from the hook and loop fastener and closer to the fixing frame.

[0022] By adopting the above technical solution, after the touchscreen conversion film is used up, it can be rolled into a cylindrical shape. Then, the straps are wrapped around the cylindrical film, and the hook side of the Velcro is attached to the fleece side, thus securing the film and preventing it from coming loose. Rolling up the film makes it convenient to store or carry, greatly improving space utilization.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Utilizing the magnetic attraction of a soft magnetic block, the conversion film can be easily installed on an electronic screen and interact with the electronic device via a USB interface, thus adding touchscreen functionality. Employing a transparent touch-sensing layer and a flexible circuit layer, along with a fixed frame design, the touchscreen conversion film is suitable for electronic screens of various sizes and shapes, achieving low-cost and high-efficiency addition of touchscreen functionality to older devices.

[0025] 2. The buffer can be made of silicone pads, micro springs or other elastic materials with buffering function. When the touch screen conversion film is attached to the electronic screen, the buffer provides appropriate buffering force to ensure that the touch screen conversion film and the electronic screen are tightly attached while avoiding damage to the electronic screen due to excessive adhesion.

[0026] 3. When the user installs the touchscreen conversion film on the electronic screen, flipping the L-shaped limiting plate and using the elastic force of the torsion spring will clamp the electronic screen. This clamping mechanism further improves the connection stability between the touchscreen conversion film and the electronic screen. Attached Figure Description
