Description

Technical Field

[0001] This utility model relates to the field of touch screens, specifically a flexible touch screen. Background Technology

[0002] In ultra-thin, flexible, transparent CPI touchscreens: CPI (colorless polyimide) material boasts high transparency, ensuring visual clarity and transparency of the touchpad, allowing users to clearly see the screen content. Simultaneously, it possesses excellent flexibility, capable of withstanding a certain degree of bending and folding. This is crucial for ultra-thin, flexible touchpads, enabling them to adapt to devices with various shapes and design requirements, while maintaining normal performance even when bent or folded. Furthermore, CPI material exhibits good heat resistance and chemical stability, maintaining stable performance under different environmental conditions and being less affected by factors such as temperature and humidity. Its role in the touchpad: As a key component of the touchpad, CPI material's high transparency ensures that light can pass through smoothly without affecting the display effect; its excellent flexibility allows the touchpad to be designed in an ultra-thin form and applied to flexible or foldable devices.

[0003] The edges and corners of a flexible CPI touchscreen are often stress concentration points. When a flexible touchscreen is installed in the display screen, its thickness is designed to be uniform with the surface thickness. As a result, the edges and corners of the flexible touchscreen have low impact resistance and are prone to damage, which reduces the lifespan of the flexible touchscreen. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible touch screen to solve the defects mentioned in the background art, such as the thickness of flexible CPI touch screen being uniformly consistent with its surface thickness during design, resulting in low impact resistance at the edges and corners of the flexible touch screen, making it prone to damage and thus reducing the service life of the flexible touch screen.

[0005] To achieve the above objectives, a flexible touch screen is provided, including an outer frame, a touch screen body fixedly disposed inside the outer frame, and a gradient connecting strip wrapped around the outer side of the touch screen body. Meanwhile, a ribbon cable is fixedly disposed at the bottom of the touch screen body. A mounting groove is opened on the surface of the outer frame, and the outer frame is positioned and installed with the mounting strip at the bottom of the device screen through the mounting groove on the surface. A first receiving groove is opened on the left side surface of the outer frame, and the size of the first receiving groove is adapted to the first silicone pad. Meanwhile, the first silicone pad is snapped into the first receiving groove.

[0006] Preferably, the outer frame is rectangular, and all four ends of the outer frame are rounded.

[0007] Preferably, the interior of the outer frame is fixedly connected to the touch screen body by a gradient connecting strip, and the cross-section of the gradient connecting strip is an isosceles trapezoidal structure.

[0008] Preferably, eight sets of mounting slots are evenly opened on the surface of the outer frame, and the mounting slots are adapted to the size of the buffer sheet. At the same time, the buffer sheet is mounted inside the mounting slots, and the depth of the mounting slots is greater than the thickness of the buffer sheet.

[0009] Preferably, the mounting slots and buffer sheets are both arranged in a straight line, and two sets of mounting slots and buffer sheets are provided on each of the four sides of the outer frame.

[0010] Preferably, a second receiving groove is formed on the right side surface of the outer frame, and the second receiving groove is adapted to the size of the second silicone pad, while the second silicone pad is fitted inside the second receiving groove.

[0011] Preferably, the second silicone pad and the first silicone pad are symmetrical about the touch screen body, and both the second silicone pad and the first silicone pad are arranged in a straight line. At the same time, the depth of the second silicone pad is equal to the depth of the second receiving groove, and the depth of the first silicone pad is equal to the depth of the first receiving groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model designs the gradient connecting strip between the touch screen body and the outer frame as an isosceles trapezoid. The gradient connecting strip adopts a gradient thickness design to avoid sudden changes in thickness and reduce stress concentration. The thickness of the touch screen body is less than the thickness of the outer frame. The outer frame is usually the stress concentration point. Increasing the thickness of the outer frame enhances the impact resistance of the outer frame and improves the service life of the touch screen body.

[0014] 2. This utility model provides a first receiving groove and a second receiving groove on both sides of the outer frame, and inserts a first silicone pad and a second silicone pad into the interior of the first receiving groove and the second receiving groove, respectively. The first silicone pad and the second silicone pad form a buffer area for the touch screen body. When the touch screen body is subjected to external force, the first silicone pad and the second silicone pad can absorb energy by deforming, thereby reducing the damage caused by external force to the device.

[0021] Please see Figure 1-5 This utility model provides a flexible touch screen, including an outer frame 1, a touch screen body 6 fixedly disposed inside the outer frame 1, and a gradient connecting strip 2 wrapped around the outer side of the touch screen body 6. At the same time, a ribbon cable 9 is fixedly disposed at the bottom of the touch screen body 6. A mounting groove 4 is opened on the surface of the outer frame 1, and the outer frame 1 is positioned and installed with the mounting strip at the bottom of the device screen through the mounting groove 4 on the surface. A first receiving groove 7 is opened on the left side surface of the outer frame 1, and the size of the first receiving groove 7 is adapted to the first silicone pad 8. The first silicone pad 8 is fitted into the first receiving groove 7.

[0022] As a preferred embodiment, the outer frame 1 is rectangular, and the four ends of the outer frame 1 are all rounded 3.

[0023] In a preferred embodiment, the interior of the outer frame 1 is fixedly connected to the touch screen body 6 by a gradient connecting strip 2, and the cross-section of the gradient connecting strip 2 is an isosceles trapezoidal structure.

[0024] In a preferred embodiment, eight sets of mounting slots 4 are evenly opened on the surface of the outer frame 1, and the mounting slots 4 are adapted to the size of the buffer sheet 5. At the same time, the buffer sheet 5 is mounted inside the mounting slots 4, and the depth of the mounting slots 4 is greater than the thickness of the buffer sheet 5.

[0025] As can be seen from the above, during use, the outer side of the touch screen 6 is fixedly connected to the outer frame 1 via the gradient connecting strip 2. When actually installing on the device display screen, the mounting strip at the bottom of the device screen is fixed inside the multiple sets of mounting slots 4 opened on the surface of the outer frame 1. The mounting strip at the bottom of the device screen and the mounting slots 4 are elastically connected by buffer pieces 5. The buffer pieces 5 are strip structures made of rubber. The mounting slots 4 and the buffer pieces 5 together form a set of connection points between the device screen and the screen. There are eight sets of connection points between the outer frame 1 and the screen, which makes the fixed installation of the outer frame 1 and the screen more stable. At the same time, the setting of the buffer pieces 5 allows the eight sets of buffer pieces 5 to absorb some energy when the device is impacted, reducing the damage to the outer frame 1 and the screen. The four ends of the outer frame 1 are all provided with rounded corners 3. The rounded corners can better disperse stress and reduce the risk of breakage during collision.

[0026] As a preferred embodiment, both the mounting slot 4 and the buffer sheet 5 are arranged in a straight line, and two sets of mounting slots 4 and buffer sheets 5 are provided on each of the four sides of the outer frame 1.

[0027] In a preferred embodiment, a second receiving groove 71 is formed on the right side surface of the outer frame 1, and the second receiving groove 71 is adapted to the size of the second silicone pad 81, while the second silicone pad 81 is fitted inside the second receiving groove 71.

[0028] As can be seen from the above, during use, the gradient connecting strip 2 between the touch screen body 6 and the outer frame 1 is set as an isosceles trapezoid. The gradient connecting strip 2 adopts a gradient thickness design to avoid sudden changes in thickness and reduce stress concentration. The thickness of the touch screen body 6 is less than the thickness of the outer frame 1. The outer frame 1 is usually the stress concentration point. Increasing the thickness of the outer frame 1 enhances its impact resistance. In areas with less stress, such as the touch screen body 6, its thickness can be reduced to reduce overall weight and cost. The outer frame 1 has a first receiving groove 7 and a second receiving groove 71 on both sides, and a first silicone pad 8 and a second silicone pad 81 are inserted into the first receiving groove 7 and the second receiving groove 71, respectively. The first silicone pad 8 and the second silicone pad 81 form a buffer area for the touch screen body 6. When the touch screen body 6 is subjected to external force, the first silicone pad 8 and the second silicone pad 81 can absorb energy by deforming, reducing the damage caused by external force to the device.

[0029] In a preferred embodiment, the second silicone pad 81 and the first silicone pad 8 are symmetrical about the touch screen body 6, and both the second silicone pad 81 and the first silicone pad 8 are arranged in a straight line. At the same time, the depth of the second silicone pad 81 is equal to the depth of the second receiving groove 71, and the depth of the first silicone pad 8 is equal to the depth of the first receiving groove 7.

[0030] Working Principle: During operation, the outer side of the touchscreen body 6 is fixedly connected to the outer frame 1 via a gradient connecting strip 2. During actual installation on the device display screen, the mounting strip at the bottom of the screen is fixed into multiple mounting slots 4 on the surface of the outer frame 1. The mounting strip at the bottom of the screen and the mounting slots 4 are elastically connected by buffer pieces 5. The buffer pieces 5 are strip-shaped structures made of rubber. The mounting slots 4 and buffer pieces 5 together form a set of connection points between the screen and the device. Eight sets of connection points are provided between the outer frame 1 and the screen, making the installation of the outer frame 1 and the screen more stable. Simultaneously, the buffer pieces 5 absorb some energy when the device is impacted, reducing damage to the outer frame 1 and the screen. The four ends of the outer frame 1 are rounded 3, which better disperses stress and reduces the risk of breakage during collisions. The risk is mitigated by the gradient connecting strip 2 between the touchscreen body 6 and the outer frame 1, which is an isosceles trapezoid with a gradient thickness design to avoid sudden changes in thickness and reduce stress concentration. The thickness of the touchscreen body 6 is less than that of the outer frame 1, which is usually a stress concentration point. Increasing the thickness of the outer frame 1 enhances its impact resistance. In areas with less stress, such as the touchscreen body 6, the thickness can be reduced to lighten the overall weight and lower costs. The outer frame 1 has a first receiving groove 7 and a second receiving groove 71 on both sides, and a first silicone pad 8 and a second silicone pad 81 are inserted into the first receiving groove 7 and the second receiving groove 71, respectively. The first silicone pad 8 and the second silicone pad 81 form a buffer area for the touchscreen body 6. When the touchscreen body 6 is subjected to external force, the first silicone pad 8 and the second silicone pad 81 can absorb energy by deforming, thus reducing the damage caused by external force to the device.
