Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, specifically a voltage regulator-controlled touch screen. Background Technology

[0002] A voltage regulator is a device that stabilizes the output voltage. It consists of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies the signal, then drives the servo motor to rotate, changing the position of the carbon brushes in the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. Voltage regulators are generally equipped with a touch screen, which is used to control the voltage regulator.

[0003] In the existing technology, when installing the touch screen of the voltage regulator, there is a gap between the outer wall of the touch screen shell and the inner wall of the voltage regulator mounting slot, resulting in insufficient installation stability. This can easily lead to poor contact of the touch screen. In addition, the touch screen is usually protected by applying a protective film, but the protective film relies on manual alignment and application, and it is easy to shift when replacing it, affecting the protective effect on the touch screen. Utility Model Content

[0004] The purpose of this invention is to provide a touch screen controlled by a voltage regulator to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A voltage regulator-controlled touch screen includes a housing, a frame fixedly mounted on the upper surface of the housing, a touch operation screen mounted inside the frame, a protective layer provided on the upper surface of the touch operation screen, a circuit board fixedly mounted inside the housing, a filling mechanism provided on the outside of the housing, and a back plate fixedly mounted on the bottom surface of the housing.

[0007] The filling mechanism includes a spiral filling pad, the outer wall of which has several movable grooves, and reinforcing blocks are inserted into the grooves. The outer walls of the reinforcing blocks have sloping surfaces near both ends.

[0008] Preferably, a plurality of spring plates are fixedly connected to the inner wall of the movable groove, and one end of each of the spring plates is fixedly connected to the reinforcing block.

[0009] Preferably, the two inner sidewalls of the movable groove are provided with sliding grooves, and a limiting plate is slidably connected inside the sliding groove, and one end of the limiting plate is fixedly connected to the reinforcing block.

[0010] Preferably, the bottom surface of the protective layer is provided with an adhesive layer, and the upper surface of the frame and the four corners near the protective layer are all fixedly installed with limiting corner guards.

[0011] Preferably, each of the inner walls of the limiting corner protectors has an installation groove near its bottom end, and a reinforcing pad is fixedly installed inside the installation groove.

[0012] Preferably, the inner wall of the reinforcing pad has a plurality of grooves, and the plurality of grooves are evenly distributed, and the two outer walls of the protective layer are fixedly connected with pull tabs.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, when installing the touch screen, the U-shaped filling pad follows the outer shell into the voltage regulator mounting part. Together with the spring sheet and reinforcing block, it can make each reinforcing block fit tightly against the inner wall of the voltage regulator mounting part, filling the gap between the outer wall of the outer shell and the inner wall of the voltage regulator mounting part. This makes the outer shell more firmly installed and fixed to the voltage regulator. Subsequently, the elasticity of each spring sheet can also buffer the force when operating the touch screen, avoiding poor contact caused by insufficient stability of the touch screen during subsequent operation.

[0015] 2. In this utility model, when installing the protective layer, the edges and corners of the protective layer are limited by four limiting corner protectors, so that the protective layer can be accurately pasted onto the touch screen. The inner walls of the reinforcing pads installed in the mounting grooves on the four limiting corner protectors are tightly attached to the outer corners of the protective layer. The grooves increase the friction between the reinforcing pads and the outer corners of the protective layer, which can further limit and fix the protective layer, prevent displacement, and realize quick and convenient replacement of the protective layer, thus providing good protection for the touch screen.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A voltage regulator-controlled touchscreen, such as Figures 1-8 As shown, the device includes a housing 17, with a frame 1 fixedly mounted on the upper surface of the housing 17. A touch screen 2 is installed inside the frame 1, and a protective layer 3 is provided on the upper surface of the touch screen 2. A circuit board 6 is fixedly mounted inside the housing 17. The output terminal of the touch screen 2 is electrically connected to the input terminal of the circuit board 6, and the output terminal of the circuit board 6 is electrically connected to the input terminal of the voltage regulator. The voltage regulator can be controlled by the touch screen 2 in conjunction with the circuit board 6. This is existing technology and will not be described in detail. A filling mechanism is provided on the outside of the housing 17, and a back plate 5 is fixedly mounted on the bottom surface of the housing 17. The filling mechanism includes a U-shaped filling pad 4. Several movable slots 7 are opened on the outer wall of the U-shaped filling pad 4. Reinforcing blocks 8 are inserted into the movable slots 7. Sloping surfaces 18 are opened on the outer wall of the reinforcing blocks 8 near both ends. The sloping surfaces 18 can guide the reinforcing blocks 8 to retract smoothly into the movable slots 7 when under pressure, avoiding jamming.

[0029] Several spring plates 9 are fixedly connected to the inner wall of the movable groove 7. One end of each spring plate 9 is fixedly connected to the reinforcing block 8. Slide grooves 10 are provided on both inner side walls of the movable groove 7. Limiting plates 11 are slidably connected inside the slide grooves 10, and one end of the limiting plates 11 is fixedly connected to the reinforcing block 8. When the reinforcing block 8 moves, each limiting plate 11 moves along the slide groove 10 with the reinforcing block 8, which can limit the movement trajectory of the reinforcing block 8, so that the reinforcing block 8 can move smoothly into the movable groove 7 when squeezed. Under the action of the spring plate 9, the reinforcing block 8 can be driven to move out of the movable groove 7, so that each reinforcing block 8 is tightly attached to the inner wall of the voltage regulator installation part, filling the gap between the outer wall of the outer shell 17 and the inner wall of the voltage regulator installation part.

[0030] When the touchscreen is installed on the voltage regulator for control, the housing 17 is inserted into the corresponding position on the voltage regulator. During insertion, the U-shaped filling pad 4 follows the housing 17 into the voltage regulator mounting area, and each reinforcing block 8 follows the U-shaped filling pad 4 into the voltage regulator mounting area. The inclined surface on the reinforcing block 8 contacts the inner wall of the voltage regulator mounting area, and under the action of the U-shaped filling pad 4, the inclined surface 18 on the reinforcing block 8 moves along the inner wall of the voltage regulator mounting area, which can squeeze the reinforcing block 8, causing the reinforcing block 8 to move into the movable slot. 7. The internal movement compresses each spring plate 9 until the U-shaped filling pad 4 is inserted into the housing 17. Under the action of the spring plate 9, the reinforcing block 8 can be moved out of the movable groove 7, so that each reinforcing block 8 is tightly attached to the inner wall of the voltage regulator mounting part, filling the gap between the outer wall of the housing 17 and the inner wall of the voltage regulator mounting part. Subsequently, in conjunction with the elasticity of each spring plate 9, it can also buffer the force when operating the touch screen 2, so that the operating screen is more stably installed with the voltage regulator, avoiding poor contact in the future.

[0031] An adhesive layer 16 is provided on the bottom surface of the protective layer 3. Limiting corner protectors 13 are fixedly installed on the upper surface of the frame 1 and near the four corners of the protective layer 3. The inner wall of the limiting corner protector 13 is provided with a mounting groove 14 near the bottom. A reinforcing pad 15 is fixedly installed inside the mounting groove 14. Several grooves 19 are provided on the inner wall of the reinforcing pad 15. The grooves 19 increase the friction between the reinforcing pad 15 and the outer corner of the protective layer 3, which can further limit and fix the protective layer 3. The grooves 19 are evenly distributed. Pull tabs 20 are fixedly connected to both outer walls of the protective layer 3. The protective layer 3 can be easily removed and replaced through the pull tabs 20.

[0032] Specifically, the protective layer 3 can be adhered to the outer wall of the touch screen 2 via the adhesive layer 16. The adhesive layer 16 is a special substrate-free OCA double-sided adhesive with optical transparency, which shields and protects the touch screen 2. The touch screen 2 is made of tempered glass, which can effectively protect the touch screen 2. When the protective layer 3 needs to be replaced, it can be peeled off simply by pulling the tab 20. When installing the protective layer 3, the corners of the protective layer 3 are limited by the four limiting corner protectors 13, so that the protective layer 3 can be accurately attached to the touch screen 2 via the adhesive layer 16. The inner walls of the reinforcing pads 15 installed in the mounting grooves 14 on the four limiting corner protectors 13 are all in close contact with the outer corners of the protective layer 3. The grooves 19 increase the friction between the reinforcing pads 15 and the outer corners of the protective layer 3, which can further limit and fix the protective layer 3, prevent displacement, and realize quick and convenient replacement of the protective layer 3.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
