Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screen technology, and in particular to a capacitive touch screen resistant to liquid interference. Background Technology

[0002] Capacitive touchscreen technology works by sensing the electrical current of the human body. It has advantages such as multi-touch, high sensitivity, fast response time, wear resistance, long life and low maintenance cost, and has been widely used in various fields.

[0003] For example, publication number CN203673460U discloses a capacitive touchscreen resistant to liquid interference, comprising a transparent substrate, a water-resistant layer, and a flexible circuit board. The transparent substrate is disposed below the water-resistant layer. An electrode layer for a sensor, or a composite layer consisting of a sensor electrode layer and a driving electrode layer, is deposited on the transparent substrate. The flexible circuit board leads out the electrodes of the sensor electrode layer and the driving electrode layer, or the composite layer, formed by the sensor electrode layer and the driving electrode layer, through a pressing method. This capacitive touchscreen significantly improves its resistance to interference from liquid conductive media, enabling more accurate information input. However, the liquid-resistant capacitive touchscreen in this patent lacks a protective storage structure, making it susceptible to damage when not in use or during transportation, thus affecting its lifespan.

[0004] Therefore, to address the issue that the aforementioned anti-liquidity capacitive touchscreens lack a protective storage structure, making them susceptible to damage when not in use or during transportation, thus affecting their lifespan, an anti-liquidity capacitive touchscreen can be designed. By incorporating a flexible, retractable support and protective structure, the touchscreen can be conveniently placed and transported. Utility Model Content

[0005] To overcome the problem that capacitive touchscreens, which are resistant to liquid interference, lack a protective storage structure, they are easily damaged when not in use or during transportation, thus affecting their lifespan.

[0006] The technical solution of this utility model is as follows: a capacitive touch screen resistant to liquid interference, comprising an outer protective shell, a storage groove on the front side of the outer protective shell, a touch screen body disposed inside the storage groove, a sliding frame disposed outside the touch screen body, limit sliders disposed on the left and right sides of the sliding frame, limit grooves disposed on the left and right sides of the inner side of the storage groove, a drive screw disposed on the rear side of the outer protective shell, a lifting rod disposed outside the drive screw, support plates one disposed at the left and right ends of the lifting rod, and support plate two disposed at the lower end of support plate one.

[0007] Preferably, by controlling the rotation of the drive screw, the lifting rod slides down behind the outer protective shell, causing support plate one and support plate two to rotate and fold to a suitable angle, which facilitates support of the outer protective shell at different tilt angles. By pulling the sliding frame up, the touch screen body is rotated so that its touch surface faces the outer protective shell, and then the sliding frame is pushed down to the inside of the storage slot, so as to realize the storage and protection of the touch screen body and avoid damage when the touch screen is not in use or during transportation.

[0008] Preferably, the left and right sides of the touch screen body are rotatably connected to the sliding frame, and the lower end of the touch screen body abuts against the inner side of the storage slot.

[0009] Preferably, the inner sides of the sliding frame and the storage slot are adapted to each other, the limiting slider is fixedly connected to the lower ends of the left and right sides of the sliding frame, and the limiting slider is slidably connected to the inner side of the limiting groove.

[0010] Preferably, the upper and lower ends of the drive screw and the rear side of the outer protective housing are rotatably connected by a support base, and a knob is fixedly installed at the lower end of the drive screw extending to the lower end of the support base.

[0011] Preferably, the lifting rod and the drive screw are connected by external threads, and the lifting rod and the rear side of the outer protective housing fit together.

[0012] Preferably, the upper end of support plate one is rotatably connected to the end of the lifting rod, and the lower end of support plate one is rotatably connected to the upper end of support plate two.

[0013] Preferably, the lower end of the second support plate and the lower end of the rear side of the outer protective shell are rotatably connected by a connecting seat, and the first support plate and the second support plate are arranged symmetrically from left to right.

[0014] The beneficial effects of this utility model are:

[0015] This liquid-resistant capacitive touchscreen uses a control screw to rotate, causing the lifting rod to slide and descend behind the outer protective shell. This causes support plates one and two to rotate and fold to a suitable angle, facilitating support of the outer protective shell at different tilt angles. When not in use or requiring transport, support plates one and two can be flattened using the control screw for easy storage. By pulling the sliding frame upward, the touchscreen body can be rotated so that its touch surface faces the outer protective shell, and then the sliding frame can be pushed down into the storage slot, thus protecting the touchscreen body and preventing damage when it is not in use or during transport.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a capacitive touchscreen resistant to liquid interference, comprising an outer protective shell 1, a storage groove 2 on the front side of the outer protective shell 1, a touchscreen body 3 disposed inside the storage groove 2, a sliding frame 4 disposed outside the touchscreen body 3, limit sliders 5 disposed on the left and right sides of the sliding frame 4, limit grooves 6 disposed on the left and right sides of the inner side of the storage groove 2, a drive screw 7 disposed on the rear side of the outer protective shell 1, a lifting rod 8 disposed outside the drive screw 7, support plates 9 disposed at the left and right ends of the lifting rod 8, and a support plate 10 disposed at the lower end of the support plate 9. By controlling the rotation of the drive screw 7, the lifting rod 8 slides down on the rear side of the outer protective shell 1, causing the support plates 9 and 10 to rotate and fold to a suitable angle, facilitating support of the outer protective shell 1 at different tilt angles. By pulling the sliding frame 4 upward, the touchscreen body 3 is rotated so that its touch surface faces the outer protective shell 1, and then the sliding frame 4 is pushed down to the inner side of the storage groove 2, thereby realizing the storage and protection of the touchscreen body 3.

[0024] Please see Figures 2-5In this embodiment, the left and right sides of the touch screen body 3 are rotatably connected to the sliding frame 4, the lower end of the touch screen body 3 abuts against the inner side of the storage slot 2, the sliding frame 4 and the inner side of the storage slot 2 are mutually adapted, the limiting slider 5 is fixedly connected to the lower ends of the left and right sides of the sliding frame 4, and the limiting slider 5 and the inner side of the limiting groove 6 are slidably connected. The front side of the touch screen body 3 is the touch surface, and the surface of the touch surface is provided with a water-resistant layer. The inner side of the housing is provided with a mechanism that allows the sliding frame 4 to rise by pulling it up. The limiting slider 5 and the limiting groove 6 cooperate to limit and guide the sliding frame 4, causing the touch screen body 3 to detach from the storage slot 2. By rotating the touch screen body 3 so that its touch surface faces the outer protective housing 1, the sliding frame 4 is pushed down to the inner side of the storage slot 2, thereby realizing the storage and protection of the touch screen body 3.

[0025] Please see Figures 1-2 In this embodiment, the upper and lower ends of the drive screw 7 and the rear side of the outer protective shell 1 are rotatably connected by a support base. The lower end of the drive screw 7 extends to the lower end of the support base and is fixedly installed with a knob 71. The lifting rod 8 and the outer side of the drive screw 7 are threadedly connected. The lifting rod 8 and the rear side of the outer protective shell 1 are in close contact with each other. The upper end of the first support plate 9 and the end of the lifting rod 8 are rotatably connected. The lower end of the first support plate 9 and the upper end of the second support plate 10 are rotatably connected. The lower end of the second support plate 10 and the lower end of the rear side of the outer protective shell 1 are rotatably connected by a connecting base. The first support plate 9 and the second support plate 10 are symmetrically arranged. By turning the knob 71, the drive screw 7 is rotated, so that the lifting rod 8 slides down on the rear side of the outer protective shell 1, driving the first support plate 9 and the second support plate 10 to rotate and fold to a suitable angle, so as to facilitate the support of the outer protective shell 1 at different tilt angles. When not in use or when transportation is required, the first support plate 9 and the second support plate 10 can be flattened by controlling the drive screw 7 for easy storage.

[0026] During operation, the drive screw 7 is rotated by turning the knob 71, causing the lifting rod 8 to slide and descend behind the outer protective shell 1. This causes the support plate 1 9 and support plate 2 10 to rotate and fold to a suitable angle, facilitating support of the outer protective shell 1 at different angles. When not in use or for transport, the support plate 1 9 and support plate 2 10 can be flattened by controlling the drive screw 7 for easy storage. By pulling the sliding frame 4 upward, the limiting slider 5 and limiting groove 6 work together to limit and guide the sliding frame 4, causing the touch screen body 3 to detach from the storage slot 2. By rotating the touch screen body 3 so that its touch surface faces the outer protective shell 1, the sliding frame 4 is pushed down to the inside of the storage slot 2, achieving storage and protection for the touch screen body 3.

[0027] Through the above steps, by controlling the rotation of the drive screw 7, the lifting rod 8 slides down behind the outer protective shell 1, driving the support plate 1 9 and the support plate 2 10 to rotate and fold to a suitable angle, so as to provide support for the outer protective shell 1 at different tilt angles. By pulling the sliding frame 4 upward, the touch screen body 3 is rotated so that its touch surface faces the outer protective shell 1. Then, the sliding frame 4 is pushed down to the inside of the storage slot 2, so as to realize the storage and protection of the touch screen body 3. This solves the problem that capacitive touch screens that are resistant to liquid interference lack a protective storage structure, which makes them easy to be damaged when the touch screen is not in use or during transportation, thus affecting the service life of the touch screen.
